The processing and cutting device plays a crucial role in its production process. It is responsible for cutting the raw plastic material according to the predetermined size, shape and other requirements to obtain plastic cap products that meet the specifications. It is a key link in the entire production process.

[0003] In the existing high-temperature biodegradable plastic cap processing and cutting technology, common cutting devices generally consist of basic components such as processing platform, cutting tool and drive device. For example, some traditional cutting devices use fixed cutting tools, which are driven by a power source such as a motor to rotate at high speed and cut the plastic cap material placed on the processing platform.

[0004] The existing technology has the following drawbacks: In terms of tool replacement and maintenance, the traditional method of disassembling and fixing bolts with tools is cumbersome and time-consuming. In addition, during frequent disassembly and installation, workers need to operate at close range, and their bodies can easily enter the processing area. If the device is accidentally activated, it poses a safety hazard and reduces the safety of maintenance operations. Therefore, a high-temperature resistant biodegradable plastic cap processing and cutting device is proposed to solve the above problems. Summary of the Invention

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3This utility model provides an embodiment of a high-temperature resistant biodegradable plastic cap processing and cutting device, including a processing table 1. A support guide rail 2 is provided at the top of the processing table 1. The support guide rail 2 mainly supports and connects a connecting plate 4. A hydraulic rod 3 is provided through the inner wall of the support guide rail 2. The hydraulic rod 3 is an actuator that uses liquid pressure energy to achieve linear reciprocating motion; this is existing technology and will not be described in detail here. The movable end of the hydraulic rod 3 is fixedly connected to the connecting plate 4. A cutter plate 5 is detachably installed on the inner wall of the connecting plate 4. The cutter plate 5 mainly supports and connects multiple annular cutting blades 6. An annular cutting blade 6 is provided at the bottom end of the cutter plate 5. The cutting blade 6 cuts the high-temperature degradable plastic cap by rotating it, which is a conventional technology and will not be described in detail here. The inner wall of the connecting plate 4 is equipped with a limit mechanism. The right inner wall of the connecting plate 4 is elastically connected to a moving block 10 by a positioning spring 9. The moving block 10 is rectangular and matches the side groove of the tool plate 5. The moving block 10 can block the side groove of the tool plate 5 so that it cannot be moved out of the entire connecting plate 4. The top of the tool plate 5 is fixedly connected to a T-shaped block 11. The T-shaped block 11 can ensure that the tool plate 5 will not detach from the connecting plate 4 during use. The side wall of the tool plate 5 is provided with an insertion hole 12. The outer wall of the processing table 1 is provided with a protective mechanism.

[0020] The limiting mechanism includes a pull rod 8, which is slidably connected to the inner wall of the connecting plate 4. The connecting plate 4 has a corresponding slot for the pull rod 8, which allows the pull rod 8 to move along the slot. The inner side wall of the pull rod 8 is elastically connected to the connecting plate 4 through a return spring 7.

[0021] Reference Figure 1 and Figure 5 The protective mechanism includes a protective frame 16, which is slidably connected to the outer wall of the processing table 1. A contact rod 15 contacts the bottom end of the protective frame 16, and the contact rod 15 can press against the bottom end of the protective frame 16, causing the protective frame 16 to move vertically. A hinge plate 14 is fixedly connected to the bottom end of the contact rod 15, and a pressing rod 13 contacts the top end of the hinge plate 14. The hinge plate 14 is rotatably connected to the outer wall of the processing table 1. Figure 5 It can be seen that the outer wall of the processing table 1 has a raised round tube, which allows the hinge plate 14 to rotate along the raised round tube. The extrusion rod 13 is fixedly connected to the outer wall of the connecting plate 4. When the connecting plate 4 moves, it will move the extrusion rod 13 synchronously to complete the subsequent extrusion process.

[0022] Reference Figures 2-4The inner sidewall of the pull rod 8 is fixedly connected to one end of the return spring 7. When the pull rod 8 moves to the right, it stretches the return spring 7. During reset, the elastic force of the return spring 7 carries the pull rod 8 back to its original position. The other end of the return spring 7 is fixedly connected to the sidewall of the connecting plate 4. The pull rod 8 passes through and slides on the inner wall of the moving block 10. The left end of the pull rod 8 has a protruding part, which can be moved to the right sidewall of the moving block 10 to press it and cause the moving block 10 to move. The right inner wall of the connecting plate 4 is fixedly connected to one end of the positioning spring 9. When the moving block 10 moves to the right, it compresses the positioning spring 9. During reset, the elastic force of the positioning spring 9 carries the moving block 10 back to its original position. The other end is fixedly connected to the side wall of the moving block 10. The moving block 10 is slidably connected to the inner wall of the connecting plate 4. The connecting plate 4 has a slot to allow the moving block 10 to move laterally along the slot. The T-shaped block 11 is inserted into the inner wall of the support rail 2. The support rail 2 has a corresponding slot to allow the T-shaped block 11 to be inserted. The connecting plate 4 is slidably connected to the outer wall of the support rail 2. The outer wall of the moving block 10 is in contact with the side wall of the tool plate 5. The pull rod 8 is inserted into the inner wall of the insertion hole 12. The insertion hole 12 is divided into a front end and a rear end. The rear end insertion hole 12 is where the moving tool plate 5 and the pull rod 8 are not inserted. The front end insertion hole 12 is where the tool plate 5 is inserted into the pull rod 8 after it moves.

[0023] Working principle: When replacing the annular cutting blade 6 on the tool plate 5, simply pull the lever 8 to the right and stretch the return spring 7, disengaging the left end of the lever 8 from the inner wall of the rear insertion hole 12. This allows the entire tool plate 5 to be moved backward, facilitating the replacement of the annular cutting blade 6. Once the lever 8 aligns with the front insertion hole 12, release the lever 8. The reverse force of the return spring 7 will then push the lever 8 back into place, allowing it to re-insert into the inner wall of the front insertion hole 12. After the annular cutting blade 6 is properly maintained, the tool plate 5 can be reset according to the above steps. Figure 1 The initial state is sufficient. When it is necessary to replace the entire tool plate 5, simply pull the lever 8 to the right and stretch the return spring 7. Then, continue to move the lever 8 to the right until the protruding part of the left end of the lever 8 contacts the inner wall of the right end of the moving block 10. Use the protruding part of the left end of the lever 8 to squeeze the moving block 10 to the right and compress the positioning spring 9. At this time, the moving block 10 and the right end slot of the tool plate 5 will disengage, allowing the entire tool plate 5 to detach from the connecting plate 4. During installation, you can follow these steps.

[0024] When protection is applied during processing, as the hydraulic rod 3 drives the connecting plate 4 to move downward, the pressing rod 13 on its outer wall moves downward simultaneously, pressing one end of the hinge plate 14. As the hinge plate 14 rotates around the protruding round tube on the outer wall of the processing table 1, the contact rod 15 at the other end is lifted upward. The contact rod 15 pushes the protective frame 16 to slide upward along the outer wall of the processing table 1, eventually closing the cutting area and forming a protective barrier to prevent cutting debris from flying or being accidentally touched by the operator. After cutting, the protective frame 16 slides downward under its own gravity, causing the contact rod 15 to move downward, the hinge plate 14 returns to its initial angle, and the protective frame 16 no longer obstructs the working area.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
