Cutting device for impregnated paper production

Abstract

The application relates to a cutting device for impregnated paper production and belongs to the technical field of impregnated paper cutting. The cutting device comprises a workbench and a cutting machine installed on the workbench. The side of the workbench is additionally provided with a feeding deviation prevention mechanism. The feeding deviation prevention mechanism comprises a rack, a negative pressure box, a negative pressure fan, a transmission net, a driven shaft, a driving shaft and a speed reduction stepping motor. The negative pressure box is horizontally fixed in the rack. The driven shaft and the driving shaft are rotationally connected in the rack. The feeding deviation prevention mechanism is used in cooperation with a deviation rectifying machine in a production line. An additional deviation rectifying machine does not need to be additionally installed in front of the cutting machine. The impregnated paper is adsorbed on the transmission net by negative pressure and moves forward with the transmission net. In the movement process, the impregnated paper cannot be deviated due to the existence of the negative pressure, so that the subsequent cutting machine can cut accurately. The feeding deviation prevention mechanism does not need to be frequently maintained, so that the production cost is greatly saved and the cutting efficiency is improved.

Description

Technical Field

[0001] This application relates to the technical field of impregnated paper cutting, and in particular to a cutting device for impregnated paper production. Background Technology

[0002] Impregnated paper is a composite material made from non-woven wood pulp, PE, and plant fibers, impregnated with melamine glue or phenolic resin. It is characterized by high absorbency, good resistance to dissolution, and low particle detachment rate, and is mainly used as a decorative layer in cabinets, wardrobes, laminate flooring, and building formwork.

[0003] During the production process, impregnated paper needs to be cut according to production requirements. Although the cutting equipment used in the existing technology has a correction machine installed in the production line, in order to ensure accurate cutting, a separate correction machine needs to be set up in front of the cutting machine.

[0004] Because the distance between the web guiding machine and the cutting machine is short, the web guiding machine needs to have high precision and requires meticulous maintenance to maintain its efficiency. Maintenance will affect the cutting work. Therefore, in order to save production costs and improve cutting efficiency, it is urgent to improve the existing cutting equipment. Utility Model Content

[0005] The purpose of this application is to provide a cutting device for impregnated paper production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a cutting device for impregnated paper production, which adopts the following technical solution: A cutting device for impregnated paper production includes a workbench and a cutting machine mounted on the workbench. A feeding anti-deviation mechanism is also provided on the side of the workbench. The feeding anti-deviation mechanism includes a frame, a negative pressure box, a negative pressure fan, a transmission mesh, a driven shaft, a drive shaft, and a reduction stepper motor. The negative pressure box is horizontally fixed inside the frame. The driven shaft and the drive shaft are rotatably connected inside the frame, and are respectively located on both sides of the negative pressure box. The transmission mesh is sleeved on the surfaces of the driven shaft and the drive shaft. The reduction stepper motor is fixed inside the frame and is used to drive the drive shaft to rotate. A plurality of air inlets are evenly distributed on the top surface of the negative pressure box, and the bottom side of the negative pressure box is connected to the negative pressure fan.

[0007] The cutting machine includes a frame and a set of conveying rollers and a cutting assembly installed in the frame. The cutting assembly is located next to the set of conveying rollers and includes a hydraulic cylinder and a cutter.

[0008] Preferably, the frame is also symmetrically provided with baffles, the baffles are adjustablely installed on the frame, the side of the baffle is fixed with a screw, the frame is provided with a protrusion corresponding to the position of the screw, the screw passes through the protrusion, and the screw is connected with a limit nut at the position on both sides of the protrusion.

[0009] By adopting the above technical solution, the baffles on both sides can limit the movement of the impregnated paper. When the negative pressure fan stops working, the impregnated paper can be pushed to be centered between the two baffles; thereafter, when the negative pressure fan is working, the impregnated paper can always be conveyed in the center. At the same time, adjusting the position of the limiting nut can adjust the distance between the two baffles to accommodate impregnated paper of different widths.

[0010] The surface of the negative pressure box is coated with a smooth layer.

[0011] Preferably, in order to ensure stable rotation of the transmission network, both the driven shaft and the driving shaft are provided with an anti-slip layer.

[0012] Preferably, in order to receive the cut impregnated paper, a discharge conveyor is also provided on the side of the frame.

[0013] In summary, this application includes at least one of the following beneficial technical effects: The cutting device for impregnated paper production is equipped with a feeding anti-deviation mechanism, which works in conjunction with the deviation correction machine in the production line, eliminating the need for a separate deviation correction machine before the cutting machine. The impregnated paper is adsorbed onto the transmission mesh using negative pressure and moves forward with it. During this movement, the negative pressure prevents the impregnated paper from shifting position, thus ensuring accurate cutting by the subsequent cutting machine. The feeding anti-deviation mechanism requires minimal maintenance, significantly reducing production costs and improving cutting efficiency. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0018] This application discloses a cutting device for impregnated paper production, referring to... Figure 1-2 The device includes a workbench 1 and a cutting machine 2 mounted on the workbench 1. The cutting machine 2 includes a frame and a conveyor roller assembly 21 and a cutting assembly 22 mounted in the frame. The cutting assembly 22 is located next to the conveyor roller assembly 21 and includes a hydraulic cylinder and a cutter.

[0019] The side of the workbench 1 is also equipped with a feeding anti-deviation mechanism 3. The feeding anti-deviation mechanism 3 includes a frame 31, a negative pressure box 32, a negative pressure fan 33, a transmission mesh 34, a driven shaft 35, a drive shaft 36, and a reduction stepper motor 37. The negative pressure box 32 is horizontally fixed inside the frame 31. The driven shaft 35 and the drive shaft 36 are rotatably connected inside the frame 31, and the driven shaft 35 and the drive shaft 36 are respectively set on both sides of the negative pressure box 32. The transmission mesh 34 is sleeved on the surface of the driven shaft 35 and the drive shaft 36. The surfaces of the driven shaft 35 and the drive shaft 36 are both provided with an anti-slip layer. The reduction stepper motor 37 is fixed inside the frame 31 and is used to drive the drive shaft 36 to rotate. Several air inlets 321 are evenly arranged on the top surface of the negative pressure box 32. The bottom side of the negative pressure box 32 is connected to the negative pressure fan 33. The surface of the negative pressure box 32 is coated with a smooth layer.

[0020] During operation, the speed of the decelerated stepper motor 37 is synchronized with the speed of the conveying roller group 21 to facilitate material feeding.

[0021] Reference Figure 2 The frame 31 is also symmetrically provided with baffles 4. The baffles 4 are adjustablely installed on the frame 31. The side of the baffles 4 is fixed with screws 41. The frame 31 is provided with protrusions 311 corresponding to the position of the screws 41. The screws 41 pass through the protrusions 311, and limit nuts 42 are connected to the positions of the screws 41 on both sides of the protrusions 311.

[0022] By setting baffles 4 on both sides, the impregnated paper can be limited. When the negative pressure fan 33 stops working, it can push the impregnated paper to be centered between the two baffles 4; thereafter, when the negative pressure fan 33 is working, the impregnated paper can always be conveyed in the center. At the same time, adjusting the position of the limiting nut 42 can adjust the distance between the two baffles 4 to accommodate impregnated paper of different widths.

[0023] Reference Figure 1 In order to receive the cut impregnated paper, a discharge conveyor 5 is also provided on the side of the frame 31.

[0024] The implementation principle of a cutting device for impregnated paper production according to an embodiment of this application is as follows: By setting up a feeding anti-deviation mechanism 3, which works in conjunction with the deviation correction machine in the production line, there is no need to install a separate deviation correction machine before the cutting machine 2. When the feeding anti-deviation mechanism 3 is in use, the negative pressure fan 33 operates, drawing air through the negative pressure box 32 to create a negative pressure state on the surface of the transmission mesh 34. At this time, the impregnated paper is firmly adsorbed onto the transmission mesh 34 and moves forward with it. During this movement, due to the presence of negative pressure, the impregnated paper will not shift its position, thus ensuring accurate cutting by the subsequent cutting machine 2. The feeding anti-deviation mechanism 3 requires minimal maintenance, greatly saving production costs and improving cutting efficiency.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
