Abstract
Description
Technical Field
[0001] This utility model relates to the field of blister box production technology, specifically to a cleaning mechanism of a shearing device for blister box production. Background Technology
[0002] Vacuum forming is a plastic processing technique. The main principle is to heat a flat, rigid plastic sheet until it softens, then use a vacuum to adhere it to the surface of a mold, where it cools and solidifies. Vacuum-formed boxes are typically made using this process. Subsequent processing may require edge trimming or slitting, which generates plastic debris. If this debris is not cleaned properly, it can cause wear and tear on the equipment or affect the quality of the finished product.
[0003] Existing devices typically use a fan to collect debris using the negative pressure it generates. However, during operation, filters are usually installed inside the device to intercept debris and prevent it from damaging the fan. This leads to some debris clogging the filter, accumulating over time, which reduces the fan's suction power, making it difficult to collect debris effectively and thus affecting the cleaning result. Utility Model Content

Detailed Implementation
[0026] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.
[0027] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.
[0028] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0029] Example 1
[0030] Combined with appendix Figures 1 to 3 As shown, a cleaning mechanism for a shearing device used in blister box production includes a shearing table 1, a support 2 on the shearing table 1, a lifting plate 4 connected to the support 2 via a cylinder 3, a blade 5 connected to the lifting plate 4, a collection box 6 located below the shearing table 1, a drain hole 7 directly below the blade 5 on the shearing table 1, a suction pipe 8 connected to the top of the collection box 6 communicating with the drain hole 7, fans 9 on both side walls of the collection box 6, a waste box 10 pulled out inside the collection box 6, sliding holes 11 on both left and right side walls of the waste box 10, symmetrical sliding grooves 12 within the sliding holes 11, a mounting bracket 14 connected between two sliding grooves 12 via multiple springs 13, a filter screen 15 connected to the mounting bracket 14, and the filter screen 15 fixedly connected to the mounting bracket 14 by bolts. When cutting the blister box, the cylinder 3 drives the cutter 5 to descend and cut the blister box. At this time, the fan 9 creates a negative pressure environment, and the debris is sucked into the waste box 10 through the drain hole 7 for subsequent cleaning.
[0031] Under the action of the fan 9, debris is collected into the waste box 10. Some debris adheres to the filter screen 15, causing the filter screen 15 to become clogged, affecting the suction power of the fan 9. Figures 4 to 6 As shown, the slide groove 12 is equipped with a striking component that cooperates with the spring 13. There are four sets of striking components, with one set of striking components in each slide groove 12. The striking component includes a cam 16. The slide groove 12 is equipped with a motor 17. The cam 16 is connected to the output end of the motor 17. The motors 17 on the same side have the same rotation speed. When the longer end of the cam 16 rotates to the side close to the mounting bracket 14, it collides with the mounting bracket 14. There are three springs 13 in one slide groove 12, and the springs 13 are evenly arranged in the slide groove 12. The even arrangement of the springs 13 makes the mounting bracket 14 more evenly stressed.
[0032] During the debris removal process, the motor 17 drives the cam 16 to rotate, continuously impacting the mounting bracket 14. This, in conjunction with the spring 13, causes the filter screen 15 to vibrate periodically, thereby removing debris from the filter screen 15 and causing it to fall into the waste box 10. This ensures the filter screen 15 remains unobstructed and maintains the suction of the fan 9, thus ensuring the effective debris removal.
[0033] To further ensure effective debris removal, combined with the attached Figure 1 As shown, a cover 18 is connected to the lifting plate 4. Springs 19 are connected to the four corners of the upper surface of the cover 18, and the other end of the springs 19 is connected to the lifting plate 4. The cover 18 forms a relatively closed space to prevent debris from drifting into the air and to make the debris be sucked into the waste box 10. The springs 19 allow the cover 18 to adjust its position flexibly when the lifting plate 4 moves, ensuring that the cover 18 always fits the working surface.
[0034] Example 2
[0035] Based on Example 1, and in conjunction with Appendix Figure 3 and Figure 7 As shown, the center of the lifting plate 4 is connected to the mounting head 20 via a connecting rod. The mounting head 20 is located inside the cover 18, and the connecting rod is slidably connected to the cover 18. The cutter 5 is provided with a connecting screw 21 that is threadedly connected to the mounting head 20. The threaded connection between the cutter 5 and the mounting head 20 makes it convenient to replace the cutter 5.
[0036] Fan 9 may generate significant noise during operation, affecting the comfort of the working environment. (In conjunction with the attached...) Figure 1 As shown, a soundproof cover 22 is provided on the outside of the fan 9 on the collection box 6. The soundproof cover 22 has several ventilation holes 23. The design of the soundproof cover 22 effectively reduces noise during operation and reduces noise pollution.
[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
