Abstract
Description
Technical Field
[0001] This utility model belongs to the field of plastic sealing zipper technology, specifically relating to a plastic sealing zipper pressing device with detection and rewinding functions. Background Technology
[0002] Plastic sealing zippers (also known as self-locking zippers, snap fasteners, etc.) are widely used in the field of flexible packaging, such as plastic sealing bags for food, daily necessities, and industrial products. Their basic structure usually includes two sets of interlocking plastic chain straps (i.e., male and female straps). In modern production processes, these two sets of chain straps are usually produced by separate extrusion molds. Before final bag making or sales, the separate male and female straps need to be pressed together into a one-piece (one-piece) finished plastic sealing zipper roll using special equipment so that it can be directly applied to bag making machines. The current equipment generally lacks continuous online quality inspection of the zipper belt, making it impossible to detect and remove impurities in a timely manner. These impurities seriously affect the zipper's sliding performance, sealing performance, and final packaging safety. Currently, it mainly relies on inefficient post-production sampling inspection. To address this issue, we have designed a plastic sealing zipper pressing device with detection and rewinding functions to provide an alternative technical solution. Utility Model Content

[0013] 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.
[0014] Reference Figure 1-6 A zipper pressing device with detection and rewinding functions includes a frame 1, two tension adjusting frames 2 are arranged inside the frame 1, and a tension adjusting mechanism is arranged inside the tension adjusting frame 2. A first guide wheel 3 and a second guide wheel 4 are arranged on one side of the frame 1, the second guide wheel 4 is located at one end of the first guide wheel 3, a pressing mechanism for zipper pressing is arranged at one end of the frame 1, and a zipper detection component is also arranged at one end of one side of the frame 1. The tension adjustment mechanism includes a first drive motor 24. The first drive motor 24 is bolted to the other side of the equipment frame 1. A transverse rotating plate 23 is fixed to the output end of the first drive motor 24. A plurality of second adjusting wheels 22 are provided on one side of the transverse rotating plate 23. A plurality of first adjusting wheels 21 are provided inside the tension adjustment frame 2. By passing the zipper sequentially through the outer sides of the first adjusting wheels 21 and the second adjusting wheels 22, the transverse rotating plate 23 can be rotated by the operation of the first drive motor 24. The rotation of the transverse rotating plate 23 causes the second adjusting wheels 22 to rotate with the transverse rotating plate 23, so that the tension of the zipper can be adjusted. Here, the operation of the first drive motor 24 enables the transverse rotating plate 23 to rotate, thereby changing the zipper stroke between the second adjusting wheel 22 and the first adjusting wheel 21, and thus adjusting the tension of the zipper. The pressing mechanism includes a first pressing roller 5, which is located near the equipment frame 1 and rotatably connected to the equipment frame 1. A second pressing roller 6 is provided on the top of the first pressing roller 5, and a vertical hydraulic cylinder 7 is provided on the top of the second pressing roller 6. The vertical hydraulic cylinder 7 is located near the equipment frame 1 and fixedly connected to the equipment frame 1. The second pressing roller 6 has a longitudinal rotating rod 8 fixed inside. The output end of the vertical hydraulic cylinder 7 is fixedly connected to the longitudinal rotating rod 8. Through the operation of the vertical hydraulic cylinder 7, the second pressing roller 6 can be vertically lifted and lowered at the top of the second guide wheel 4, thereby enabling the pressing of zippers of different thicknesses and improving the applicability of the device. Here, the first guide wheel 3 and the second guide wheel 4 allow two interlocking zippers to enter the top of the first pressing roller 5 through the first guide wheel 3 and the second guide wheel 4. The vertical hydraulic cylinder 7 operates to make the longitudinal rotating rod 8 move vertically up and down, thereby pressing the two zippers together. The detection component includes an LED flat panel light 10, which is fixedly connected to the equipment frame 1 on one side. A laser detector 11 is installed on the top of the LED flat panel light 10. Both ends of the LED flat panel light 10 are equipped with third guide wheels 9, which are rotatably connected to the equipment frame 1 on one side. When the plastic zipper passes through the bottom outside of the third guide wheels 9, the laser detector 11 emits a focused laser beam to irradiate the particles on the surface of the plastic zipper and analyzes whether the surface of the plastic zipper is contaminated with impurities based on information such as the intensity and angle of the light. The LED flat panel light 10 serves as a backlight source, mainly used to provide uniform background illumination. When inspecting the plastic zipper, the LED light passes through the plastic zipper to help observe dust, impurities, or defects inside or on the surface. The uniform illumination of the LED flat panel light 10 can enhance the contrast, making the laser-detected signal clearer and effectively reducing the interference of ambient light. On the other side of the equipment frame 1, a second drive motor 13 is bolted. The output end of the second drive motor 13 is fixedly connected to the take-up roller 12. Through the operation of the second drive motor 13, the take-up roller 12 can rotate, thereby enabling the zipper to be wound up. Here, the laser detector 11 emits a focused laser beam to irradiate the particles on the surface of the plastic-sealed zipper, and analyzes whether the surface of the plastic-sealed zipper is contaminated with impurities based on information such as the intensity and angle of the light. The LED flat panel light 10 serves as a backlight source and is mainly used to provide uniform background lighting. Through the operation of the second drive motor 13, the winding roller 12 can rotate, thereby enabling the zipper to be wound up and stored.
[0015] The LED flat panel light 10 and the laser detector 11 can identify impurities in the plastic-sealed zipper tape, effectively preventing defective products from flowing into subsequent processes, significantly improving the reliability of finished product quality and packaging safety. After the zipper is inspected, the winding roller 12 is directly set to realize continuous winding after the zipper is pressed, eliminating the need for a separate winding process and equipment, simplifying the process, and reducing the footprint, equipment investment and manual intervention.
[0016] Working principle: Through the first guide wheel 3 and the second guide wheel 4, two interlocking zippers enter the top of the first pressing roller 5. Through the operation of the vertical hydraulic cylinder 7, the longitudinal rotating rod 8 is raised and lowered vertically, thereby pressing the two zippers together. The laser detector 11 emits a focused laser beam to irradiate the particles on the surface of the plastic-sealed zipper, and analyzes whether the surface of the plastic-sealed zipper is contaminated with impurities based on information such as the intensity and angle of the light. The LED flat panel light 10 serves as a backlight source and is mainly used to provide uniform background lighting. The operation of the second drive motor 13 enables the winding roller 12 to rotate, thereby enabling the zipper to be wound up and stored.
