Description

Technical Field

[0002] In many industries such as packaging, advertising, and electronics, PS sheet film has become a key material with its lightweight, transparency, good rigidity and easy processing properties. In actual production and application, in order to meet the diverse needs of different scenarios, PS sheet film needs to be cut. A PS sheet film cutting machine is required for the cutting process.

[0003] The existing patent document CN221136133U discloses a PS sheet film cutting machine. The utility model includes a support mechanism, a cutting mechanism for cutting the side edges of the passing PS sheet, and auxiliary mechanisms for flattening the PS sheet on both sides of the cutting mechanism.

[0004] However, due to the poor limit adjustment capability of the existing patent technology with authorization announcement number CN221136133U, it is not convenient to limit and cut films of different sizes according to cutting needs, as well as to limit and fix them in place during actual use. This affects the convenience of cutting limit adjustment and makes it difficult to limit and stabilize the cut film. As a result, manual collection and sorting of the cut film is still required after cutting, which affects the processing efficiency. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This PS sheet / film cutting machine, through its carefully designed cutting limiting mechanism, greatly enhances the ability to limit and adjust films of different cutting sizes. The servo motor drives the adjusting screw to rotate, causing the limiting screw block to move on the adjusting screw, which in turn moves the support rod and the limiting plate. The size to be cut is adjusted through the limiting plate, and the cut film is easily positioned and placed through the limiting plate, reducing the amount of manual handling work and improving processing efficiency.

[0018] 2. This PS sheet / film cutting machine further enhances the accuracy of limit adjustment by setting scale lines. When adjusting the position of the limit plate, the operator can intuitively understand the movement distance of the limit plate through the scale lines, so as to more accurately adjust the limit plate to the required position and ensure the accuracy of the cutting size.

[0019] 3. This PS sheet / film cutting machine uses an infrared laser displacement sensor to monitor the position of the PS sheet / film on the limiting plate in real time and feeds the data back to the PLC controller. This facilitates the determination of the cutting size accuracy and thus the control of the hydraulic cylinder. Under the control of the PLC controller, the hydraulic cylinder can precisely control the descent speed and force of the cutting blade, ensuring a smooth and efficient cutting process.

[0027] The cutting limiting mechanism 4 includes a servo motor 401. The servo motor 401 is fixedly installed on one side of the cutting table 1. An adjusting screw 402 is fixedly installed on the output shaft end of the servo motor 401. The adjusting screw 402 is located inside the cutting table 1. A support mounting block 403 is fixedly installed on the inner wall of one side of the cutting table 1. The side of the adjusting screw 402 away from the servo motor 401 is rotatably connected to the side of the support mounting block 403. A limiting screw block 404 is threadedly connected to the outer end of the adjusting screw 402. A connecting guide rod 405 is fixedly installed on the side of the cutting table 1 away from the adjusting screw 402. A connecting slider 406 is movably mounted on the outer end of the connecting guide rod 405. A support rod 407 is fixedly mounted on the top of the limiting screw block 404 and the connecting slider 406. The support rod 407 extends through the limiting through groove 3 to the top of the cutting table 1. A limiting plate 408 is fixedly mounted on the side of the support rod 407 near the supporting gantry frame 2. When the servo motor 401 is started, the adjusting screw 402 is rotated, causing the limiting screw block 404 to move linearly on the adjusting screw 402, which in turn moves the support rod 407 and the limiting plate 408, and at the same time moves the connecting slider 406 on the connecting guide rod 405.

[0028] A PLC controller 5 is fixedly installed on one side of the supporting gantry frame 2. The PLC controller 5 is electrically connected to the servo motor 401. A scale line 6 is fixedly installed on the top of the cutting table 1. A hydraulic cylinder 7 is fixedly installed on the top of the supporting gantry frame 2. The hydraulic cylinder 7 is electrically connected to the PLC controller 5. A movable push rod 8 is fixedly installed at the output end of the hydraulic cylinder 7. The movable push rod 8 extends to the bottom end of the supporting gantry frame 2. A support plate 9 is fixedly installed at the bottom end of the movable push rod 8. A cutting blade 10 is fixedly installed at the bottom end of the support plate 9. Support grooves 11 are opened on the two adjacent sides of the supporting gantry frame 2. Support slide rods 12 are fixedly installed on both sides of the support plate 9. The support slide rods 12 are movably connected inside the support grooves 11. A cutting seat 13 is fixedly installed at the top of the cutting table 1, located in the middle of the supporting gantry frame 2. A limit plate is also fixedly installed. A mounting plate 14 is fixedly installed on the side of the gantry frame 2 near the 408. An infrared laser displacement sensor 15 is fixedly installed at the bottom of the mounting plate 14. The infrared laser displacement sensor 15 is electrically connected to the PLC controller 5. Several support columns 16 are evenly fixedly installed at the bottom of the cutting table 1. A load-bearing reinforced base plate 17 is fixedly installed at the bottom of the cutting table 1. Several support feet 18 are evenly fixedly installed at the bottom of the load-bearing reinforced base plate 17. The infrared laser displacement sensor 15 monitors the position of one end of the film from the limiting plate 408. When the film is detected to be close to the limiting plate 408, the infrared laser displacement sensor 15 transmits the data to the PLC controller 5. The PLC controller 5 starts the hydraulic cylinder 7 to adjust the height of the movable push rod 8, so that it pushes the support plate 9 and the cutting blade 10 down.

[0029] Working Principle: When film cutting is required, the PS sheet film cutting machine is first stably placed in the desired position using the support feet 18. An external power supply is connected to power the equipment. According to the cutting requirements, the servo motor 401 is started to rotate the adjusting screw 402, causing the limit screw 404 to move linearly on the adjusting screw 402. This moves the support rod 407 and the limit plate 408, simultaneously moving the connecting slider 406 on the connecting guide rod 405. As the limit plate 408 moves, the size of the film to be cut is determined by the scale line 6. After adjustment, the film roll is transferred to the cutting table 1 via the conveyor roller. One end of the film is then... The film is transmitted to one side of the limiting plate 408. The infrared laser displacement sensor 15 monitors the position of one end of the film from the limiting plate 408. When the film is detected to be close to the limiting plate 408, the infrared laser displacement sensor 15 transmits the data to the PLC controller 5. The infrared laser displacement sensor 15 is an OPTEXCD33-30NA PLC model. The controller 5 starts the hydraulic cylinder 7 to adjust the height of the movable push rod 8, which pushes the support plate 9 and the cutting blade 10 down. Through the cooperation of the cutting blade 10 and the cutting seat 13, the film is cut. The limiting plate 408 limits and places the cut film, eliminating the need for manual handling.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
