Description

Technical Field

[0001] The utility model relates to the field of silicon oil paper processing, and particularly relates to a paper cutting device. Background Technique

[0002] Silicon oil paper is an indispensable raw material in the packaging industry. Due to the oil-proof property of silicon oil paper, it is generally used for food industry packaging.

[0003] In the prior art, when a general paper cutting device cuts silicon oil paper, the rotation of the feeding roller drives the movement of the silicon oil paper for feeding, and then the cutting edge presses down to cut the silicon oil paper. However, during the process of the cutting edge pressing down, since the cutting edge will squeeze and pull the silicon oil paper when cutting it, it is easy to cause the silicon oil paper to be torn during the cutting process, resulting in a reduction in the quality of paper cutting. At the same time, during the feeding process, since the feeding of the silicon oil paper is driven by the friction force when the feeding roller rotates, and due to the oil-proof property of the silicon oil paper, the friction force between the surface of the feeding roller and the silicon oil paper is small, which is likely to cause the silicon oil paper to slip and displace during the conveying process, thereby leading to a decrease in the accuracy of cutting the silicon oil paper and also reducing the quality of the finished product. For this reason, a paper cutting device is proposed to solve the above problems. Content of the Utility Model

[0031] Refer to Figure 1 , Figure 3 , the feeding mechanism further includes a support frame 11 for playing a stabilizing role, the support frame 11 is fixedly installed on the top of the base 1, a pressure roller 12 is arranged inside the support frame 11, and the silicone paper is pressed tightly on the top surface of the electric conveying roller 10 through the downward pressure of the pressure roller 12 to increase the friction between the paper and the surface of the electric conveying roller 10, thereby improving the stability of feeding and avoiding the silicone paper from slipping due to insufficient friction. The feeding mechanism further includes a slider 13, a sliding groove 14 is opened on the inner wall of the support frame 11, the slider 13 is slidably installed on the inner wall of the sliding groove 14, the sliding direction of the slider 13 is up and down, the number of sliders 13 is set to two groups, and the front and rear sides of the pressure roller 12 are rotatably installed on one side where the two groups of sliders 13 are close to each other.

[0032] Refer to Figure 3, the feeding mechanism further includes a second spring 15. The second spring 15 is fixedly installed on the top of the slider 13. The top of the second spring 15 is fixedly connected to a moving block 16. The second spring 15 applies a downward elastic force to the slider 13. The moving block 16 is slidably installed on the inner wall of the chute 14. The sliding direction of the moving block 16 is up and down. The feeding mechanism further includes a vertically arranged threaded rod 17. The threaded rod 17 passes through and is threadedly installed on the inner wall of the support frame 11. When the threaded rod 17 rotates, it will also linearly displace up and down under the action of the thread. The bottom of the threaded rod 17 contacts the top of the moving block 16.

[0033] Working principle: When in use, pass the silicon oil paper under the cutting edge 6 and then feed it between the electric conveying roller 10 and the pressing roller 12. Start the power supply of the electric conveying roller 10 to make the electric conveying roller 10 rotate and drive the silicon oil paper to move. Then start the power supply of the electric cylinder 4. The electric cylinder 4 works to drive the cutting device body 5 to displace downward. Before the cutting device body 5 displaces downward and contacts the silicon oil paper, the pressing block 8 will first contact the silicon oil paper. The pressing block 8 presses the silicon oil paper on the ground of the base 1 and applies a pre-tightening force to prevent the silicon oil paper from being torn when the cutting edge 6 cuts the silicon oil paper. At the same time, when the pressing block 8 moves downward, it will receive the reaction forces from the base 1 and the silicon oil paper, causing the pressing block 8 to displace upward relative to the cutting device body 5 against the elastic force of the first spring 9, and then the pressing block 8 completely enters the interior of the cutting device body 5. Therefore, the contact between the pressing block 8 and the silicon oil paper will not hinder the displacement of the cutting device body 5. The displacement of the cutting device body 5 drives the cutting edge 6 to displace downward and completes the cutting and segmentation work of the silicon oil paper.

[0034] On the basis of the above work, by rotating the threaded rod 17, the rotation of the threaded rod 17 drives the moving block 16 to displace downward, and then the moving block 16 displaces downward and compresses the second spring 15, so that the length of the second spring 15 is compressed, thereby increasing the downward pressure of the second spring 15 on the slider 13 and the pressing roller 12. According to the processing characteristics of the silicon oil paper, the downward pressure of the pressing roller 12 on the silicon oil paper is adjusted accordingly to ensure that the silicon oil paper does not slip during transportation and is not torn due to excessive pulling force, improving the control accuracy and the quality of the processed products.
