Paper cutter classification, characteristics and brand

A small paper cutter

Small paper cutters are divided into thick-layer paper cutters and small office paper cutters

(A), thick layer paper cutter

Thick paper cutters are also called manual cutters from the drive method, desktop cutters from the placement position, and so on. This type of paper cutter is mainly suitable for trimming paper before stapling a small number of documents. This paper cutter is widely used in office or finance, photo studios, and digital printing shops.

Thick-layer paper cutter features:

1) The maximum cut size is generally about 430mm;

2) Small, easy to use and does not take up too much space;

3) The cutting accuracy of the cutting object is not high;

4) Cheap and economical.

Thick chopper brand: Li Qiao, Ronghua, Simi, Asia Pacific, etc.

(II) Small Office Paper Cutter

The small-sized office paper cutter has a relatively complex structure and is mainly composed of a main body, a worktable, a paper pressing mechanism, a paper pushing mechanism, and a cutting mechanism. This type of paper cutter is mainly suitable for paper neatly before stapling a large number of documents. This paper cutting machine is widely used in modern digital printing, high-end office, library, national public service, and small and medium-sized printing.

From the push paper mechanism and even the cutting mechanism drive method is divided into manual paper cutting machine (pure mechanical structure), electric paper cutting machine;

The paper press mechanism is divided into mechanical press and hydraulic press.

From the size display mode and the positioning of the pusher, the printer is divided into a digital cutter and a program-controlled cutter. (The pure mechanical structure cutter is equipped with a steel ruler on the surface of the table, and the control and digital display of the pusher Like a paper machine). The main difference between the digital cutting machine and the program-controlled paper cutting machine is the control of the paper pushing mechanism. The program controlled paper cutting machine not only greatly improves the efficiency, but also effectively reduces the labor intensity of the operator.

The high-end small office paper cutter is not only reflected in the stability of the cutting accuracy and performance, but also has multiple protections in terms of security, which is embodied in the differential protection of hands and photoelectric protection.

Small Office Cutter Features:

1) The cutting width is generally between 430mm-800mm;

2) Small, easy to use and does not take up too much space;

3) Can cut a large number of crops;

4) The cutting precision of the cutting object is high;

5) The price ranges from a few thousand to more than ten thousand yuan depending on the size and configuration of the cutting format.

Second, flat sheet cutter

The flat sheet cutter is a kind of cutting machine and has a wide range of applications. It can be used to cut paper, leather, plastic, paperboard and other materials. The paper cutting machine is mainly composed of a host (also called a gantry), a worktable, a paper pushing mechanism, a paper pressing mechanism, a cutting mechanism and the like. The paper-pushing mechanism is used to push the paper positioning and make the following rules. The paper-pressing mechanism presses the well-positioned paper to ensure that the original positioning accuracy is not damaged during the cutting process. The cutting mechanism is used to cut the paper and the side baffle is used. Side baffle, workbench plays a supporting role.

Printing, packaging, bookbinding, etc. The production of finished products from the opening to the printing and the cutting of the bound woolen books require cutting by the cutting machine, so the cutting machine is an important equipment for postpress processing. Zhang Zhang Cutter is widely used in printing, binding, packaging, paper products processing plants.

(A), Zhang Zhang Cutter cutting process:

1) The position of the pusher is determined according to the size of the paper being cut;

2) Place the paper that has been twisted against the front surface of the pusher and the side fences for paper positioning;

3) The paper press first presses down the paper, and then the knife cuts again to cut the paper;

4) After the cutting is completed, the cutter first leaves the stack and returns, and then the platen rises again.

(b) Classification of flat sheet cutters

1) Flat sheet cutters are divided into electric cutters by means of the driving mechanism of the pusher mechanism. (The pusher can only be realized by manually pressing the button or operating the corresponding mechanism by controlling the motor or the mechanical actuator. Positioning), Programmable Cutter (Automatic Positioning of the Pusher by Program Control System, Positioning Method of Electric Cutter, and Intelligent Digital Cutter Between Two Methods) The control system automatically locates roughly and then manually adjusts to achieve accurate positioning);

2) The program-controlled paper cutter is divided into three methods: stepper motor control, frequency conversion speed control, and AC servo control.

The stepping motor control and frequency conversion speed control methods can reach ±0.1mm on the positioning accuracy of the paper cutter pusher, and the speed can reach 8-14 meters/minute (The specific accuracy and speed can be achieved by the manufacturer. The difference between the control system and the selected electrical components will be quite different. However, the stepping motor control mode is more harsh when starting up, and it is not favored by users of many cutter manufacturers and cutters.

The AC servo control method has a great breakthrough in the accuracy and speed of the paper feeder pusher compared to the frequency conversion speed control. The positioning accuracy can reach ±0.025-±0.015mm, and the pushing speed can reach 16-20. The meter/minute (accuracy and speed achieved by the manufacturer will vary greatly depending on the control system and the selected electrical components used by the manufacturer).

3) From the operating interface (operation mode) of the program-controlled paper cutter, it is divided into three modes: touch-sensitive, touch screen, key and touch screen.

The program-controlled paper cutter that was operated by the key mode appeared at the earliest time, which doubled the efficiency of the digital paper cutter, improved the work efficiency for many users, created more wealth, and was greatly favored by customers, but after the new technology came out This method is inconsistent with the touch screen operation mode in terms of intuitive and simple operation. The touch screen operation method can easily realize functions such as division, equidistant, loop size, use of a calculator, and calculation result input program, etc., and the operation is simple and intuitive (a key operation mode requires a combination of several keys when performing some functions. Can be achieved, many customers because the operator can not find replacement instructions, consult the manufacturer after using the method); on the screen has a direct display of the detection status of various operating links on the machine, for the elimination of common faults to provide a great convenience This saves both time and money for the customer and manufacturer of the paper cutting machine.

The dual mode of buttons and touch screens can be used in combination to meet the old habits of some operators. At the same time, there is more than one input method, and the durability is relatively improved, but the touch screen operation mode is designed by the interface of the paper cutter manufacturer. The operation menu is reasonable and the selected screen quality is stable and reliable. Its significance is not very great.

4) It is divided into mechanical pressure paper and hydraulic pressure paper from the driving mode of the paper press mechanism;

The hydraulic pressure paper way can more accurately ensure the equal length tolerance precision after cutting the cutting material (commonly known as the upper and lower knife precision), especially when the cutting density is larger, the difference is especially obvious. Therefore, with the emergence of hydraulic pressure paper cutters, mechanical paper presses are no longer used by customers who require high cutting accuracy. Both the platen mechanism and the clutch of the cutting mechanism are hydraulically driven and are also called full hydraulic or dual hydraulic cutters. The full hydraulic or double hydraulic paper cutter has a greater cutting force, and has a distinct advantage when the cutting density is higher, the clutch is not easy to slip, and the clutch clearance is not frequently adjusted.

5) From the size display mode and the positioning of the paper feeder, it is divided into a digital paper cutting machine and a program-controlled paper cutting machine. (The mechanical structure of the paper cutting machine is generally equipped with a steel ruler, and controls the number of paper feeders. The same as the paper cutter.

6) From the flat sheet cutter width width (maximum cutting width) is divided into split paper machine (also called semi-open paper cutter), full-cut paper cutter (full sheet cutter) And so on, there have been a lot of articles mentioned, the author will not repeat them. The high-end flat sheet cutter is not only reflected in the precision of cutting, the stability of performance and the selection of materials, components and control systems, but also has multiple protections in terms of safety, which is embodied in the differential protection of both hands and photoelectric protection. , electronic knife locks and so on.

(C), Zhang Zhang Cutter features:

1) The cutting width is generally between 920mm-2200mm;

2) Involving comprehensive control of machinery, electrical appliances and hydraulics;

3) Can cut a large number of crops;

4) The cutting accuracy of the cutting object is high;

5) Prices range from a few tens of thousands to hundreds of thousands of yuan depending on the size and configuration of the cutting format.
