[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figures 1-6, an embodiment provided by the present utility model: a cutting device for plastic sheet processing, including a frame body 1, a clamping table 2 is fixedly connected to the top of the frame body 1, two clamping plates 10 are slidably connected inside the clamping table 2, a mounting plate 7 is fixedly connected to the inner bottom wall of the clamping table 2, a cylinder 1 4 is fixedly connected to one side of the mounting plate 7, the output end of the cylinder 1 4 is fixedly connected to a connecting plate 5, the top of the connecting plate 5 is fixedly connected to the bottom of one of the clamping plates 10, a rotating shaft 6 is rotatably connected to the middle side of the inner bottom wall of the frame body 1, a turntable 3 is fixedly connected to the top of the rotating shaft 6, a connecting rod 8 is arranged between the turntable 3 and the clamping plate 10, two sliding rods 9 are fixedly connected inside the clamping table 2, a lead screw 12 is threadedly connected to the upper side inside the clamping plate 10, a pressing plate 11 is fixedly connected to the bottom of the lead screw 12, a linear module 13 is fixedly connected to the top of the frame body 1, a cylinder 2 14 is arranged at the bottom of the linear module 13, the output end of the cylinder 2 14 is fixedly connected to a cutting machine 28, a bottom plate 15 is fixedly connected to the outside of the frame body 1, a waste box 16 is fixedly connected to the top of the bottom plate 15, a dust suction fan 17 is fixedly connected inside the waste box 16, a filter screen 19 is slidably connected to the middle side inside the frame body 1, a dust suction pipe 26 is fixedly connected inside the waste box 16, one end of the dust suction pipe 26 is fixedly connected to a dust suction head 27, a drawer 18 is slidably connected to the lower side inside the waste box 16, and a fixing component is arranged outside the waste box 16, and the fixing component is used for installing and disassembling the filter screen 19.

[0034] Specifically, during the operation, first place the plastic sheet on the clamping table 2. Subsequently, drive the cylinder 1 4 to start, driving the connecting plate 5 to move. This action causes the connecting plate 5 to further push the clamping plate 10, making it slide along the outside of the sliding rod 9. At the same time, the connecting rod 8 is also rotating, driving the rotation of the turntable 3 and the rotating shaft 6. This rotation acts on the other connecting rod 8, causing the clamping plate 10 to slide along the other sliding rod 9, thereby realizing the lateral clamping of the plastic sheet. Then, by rotating the lead screw 12, the pressing plate 11 moves downward to realize the longitudinal clamping of the plastic sheet. This design allows the device to adapt to plastic plates of different lengths and thicknesses, ensuring wide applicability. Once the clamping is completed, the cutting machine 28 is controlled to move left and right through the linear module 13, and the driving cylinder 2 14 adjusts the vertical cutting distance between the cutting machine 28 and the plastic plate to accurately complete the cutting operation. When dealing with waste chips, start the dust suction fan 17, and the waste chips are sucked into the dust suction pipe 26 through the dust suction head 27 and finally enter the inside of the waste box 16. Under the action of the filter screen 19, the waste chips are blocked and fall into the drawer 18, effectively collecting and managing the generated waste.

[0035] Refer to Figure 5 and Figure 6The fixed component includes a thin shell 24, one side of which is fixedly connected to the outside of the waste box 16, a thin shell 23 is fixedly connected to the top of the thin shell 24, a plug rod 25 is slidably connected inside the thin shell 24, one side of the plug rod 25 is fixedly connected to a baffle 20, the other side of the plug rod 25 is sleeved with a spring 22, and a blocking rod 21 is set on the top of the baffle 20.

[0036] Specifically, in order to clean the filter 19, the operation of pulling the plug rod 25 is first performed. This operation will cause the baffle 20 to move outward, and the spring 22 will be compressed, thereby releasing the blocking rod 21, so that it slides from the inside of the thin shell 23 into the thin shell 1 24. This design cleverly prevents the plug rod 25 from being inserted into the filter 19 again due to the elastic force of the spring 22 after the hand is released. Next, the filter 19 can be easily removed for cleaning. When the filter 19 needs to be reinstalled, the blocking rod 21 is first pulled upward. At this time, under the elastic force of the spring 22, the baffle 20 and the plug rod 25 will move inward until both are firmly penetrated through the waste box 16 and plugged into the inside of the filter 19. At this point, the whole process is completed, and the filter 19 is safely and effectively installed back to its original position.

[0037] Reference Figures 1-6 The inside of the clamping plate 10 is slidably connected to the outside of the sliding rod 9, one end of the connecting rod 8 is rotatably connected to the bottom of the clamping plate 10, and the other end of the connecting rod 8 is rotatably connected to the outer edge of the turntable 3. One side of the dust collector 27 is fixedly connected to the lower inner part of the frame 1, one end of the spring 22 is fixedly connected to one side of the baffle 20, and the other end of the spring 22 is fixedly connected to the inner wall of the thin shell 24. The outside of the baffle 20 is slidably connected to the inside of the thin shell 24. The plug-in rod 25 penetrates the waste box 16 and is plugged into the filter 19. The upper side of the blocking rod 21 is slidably connected to the inside of the thin shell 23, and the lower side of the blocking rod 21 is slidably connected to the inside of the thin shell 24.

[0038] Specifically, the design of the clamping plate 10 enables it to slide outside the sliding rod 9. In this way, under the action of the driving cylinder 1-4, the movement of the clamping plate 10 can be realized, and then the lateral clamping of the plastic sheet can be achieved. One end of the connecting rod 8 is rotatably connected to the bottom of the clamping plate 10, and the other end is rotatably connected to the outer edge of the turntable 3, ensuring that the movement of the clamping plate 10 is synchronized with the rotation of the turntable 3, thus realizing the stable clamping of the plastic sheet. The dust suction head 27 is fixed to the lower part inside the frame body 1 and is used to directly contact and suck the waste chips generated during the plastic cutting process. Its design ensures the efficient collection of waste chips, reduces environmental pollution, and improves the safety of operation. The two ends of the spring 22 are respectively fixed to one side of the baffle 20 and the inner wall of the thin shell 1-24, providing a restoring force for the baffle 20, so that after the user's operation, the baffle 20 can automatically reset to maintain the working state of the system. The sliding connection design of the baffle 20 inside the thin shell 1-24 enables it to move outwards during the user's operation, facilitating the disassembly and assembly of the filter screen 19, and automatically resetting under the action of the spring 22, ensuring the continuity and stability of the system. The insertion rod 25 runs through the entire system and is inserted into the filter screen 19 to form a closed channel, which is used to take out the filter screen 19 during cleaning and also serves the function of keeping the filter screen 19 firmly installed in the waste chip box 16. The up-and-down sliding connection design of the blocking rod 21, on the one hand, ensures that the baffle 20 and the insertion rod 25 can move smoothly during the user's operation, and on the other hand, also ensures that these components can automatically reset under the action of the spring 22 to maintain the normal operation state of the system.

[0039] Working principle: When in use, first place the plastic sheet on the clamping table 2. At this time, the driving cylinder 1-4 drives the connecting plate 5 to move, and then one of them drives the clamping plate 10 to slide outside the sliding rod 9. At the same time, one of the connecting rods 8 rotates, causing the turntable 3 and the rotating shaft 6 to rotate, and then the other connecting rod 8 also rotates synchronously, pulling the other clamping plate 10 to slide outside the other sliding rod 9 to laterally clamp the plastic sheet. At this time, rotate the screw rod 12 to drive the pressing plate 11 to move downwards to achieve the longitudinal clamping of the plastic sheet. Plastic sheets of different lengths and thicknesses can be clamped. After clamping, at this time, control the cutting machine 28 to move left and right through the linear module 13, and the driving cylinder 2-14 controls the vertical cutting distance between the cutting machine 28 and the plastic sheet. After cutting, the cutting work is carried out;

[0040] When waste chips are generated, the dust suction fan 17 is driven at this time, and then the waste chips are sucked into the interior of the waste chip box 16 through the dust suction head 27 and the dust suction pipe 26. Blocked by the filter screen 19, they enter the interior of the drawer 18. When it is necessary to disassemble the filter screen 19 for cleaning, the insertion rod 25 is pulled. This action will drive the baffle 20 to move outwards, and at the same time the spring 22 will be compressed, and the blocking rod 21 will slide from the interior of the thin shell two 23 into the thin shell one 24. This design prevents the insertion rod 25 from re-entering the filter screen 19 under the elastic force of the spring 22 after the hand is released. At this time, the filter screen 19 can be taken away. When it is necessary to install the filter screen 19, only the blocking rod 21 needs to be pulled upwards at this time. At this time, under the elastic force of the spring 22, the baffle 20 and the insertion rod 25 will move inwards until they firmly penetrate the waste chip box 16 and are inserted into the interior of the filter screen 19, and the installation is completed at this time.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
