Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] Example 1: like Figure 1 , Figure 2 , Figure 3 , Figure 4 Figure 5 Figure 12As shown, a zipper forming device with detection function includes a workbench 10, a first support frame 13 is provided above the workbench 10, and a sliding plate 14 is slidably arranged inside the first support frame 13. A long hole 11 is provided below the sliding plate 14 and above the worktable 10. A lower mold 12 is slidably disposed inside the long hole 11. An upper mold 15 is provided above the lower mold 12 and above the lower end of the sliding plate 14. The lower mold 12 and the upper mold 15 cooperate to form the injection cavity of the zipper teeth. An injection molding machine is provided on the upper end of the sliding plate 14. The discharge port of the injection molding machine is connected to the injection cavity of the upper mold 15. A plurality of first push cylinders are provided on the upper end of the first support frame 13. The output ends of the first push cylinders all pass through the first support frame 13 and are fixedly connected to the upper end of the sliding plate 14. A fourth support frame 54 is provided below the lower mold 12 and below the worktable 10. A second push cylinder is provided on the lower end of the fourth support frame 54. The output end of the second push cylinder passes through the fourth support frame 54 and is fixedly connected to the lower end of the lower mold 12.

[0021] A third support frame 47 is provided on one side of the first support frame 13 on the side wall of the workbench 10. A first discharge roller 48 is rotatably arranged inside the third support frame 47. A second discharge roller 49 is rotatably arranged on the inner side wall of the third support frame 47 above the first discharge roller 48. A first motor is provided on one side of the first discharge roller 48 to drive its rotation. When the zipper is injection molded, the meshing rotation of the first discharge roller 48 and the second discharge roller 49 firstly forms a horizontal pull on the zipper strip required for injection molding. After the strip of the zipper to be injection molded is moved between the lower mold 12 and the upper mold 15, multiple first... The output ends of the push cylinder and multiple second push cylinders respectively drive the lower mold 12 and the upper mold 15 to move vertically and engage with each other, clamping and fixing the zipper strip and forming an injection cavity. Then, the injection molding machine is started, and the injection molding machine injects into the injection cavity between the lower mold 12 and the upper mold 15, so that the injection-molded zipper teeth adhere to the zipper strip. Then, the first push cylinder and the second push cylinder are started again to drive the lower mold 12 and the upper mold 15 to separate, disengaging from the clamping of the molded zipper. Then, the first motor drives the first discharge roller 48 to rotate, and the second discharge roller 49 and the clamping rotation of the first discharge roller 48 on the zipper strip form the unloading of the zipper after production.

[0022] In the above process, cooling pipes are provided inside both the lower mold 12 and the upper mold 15, and a cooling water tank, a water-cooled circulating water pump, and a water-cooled circulating water pipe are also provided below the worktable 10 to perform water-cooled circulating cooling treatment inside the lower mold 12 and the upper mold 15, thereby forming cooling after the injection molded zipper is formed, so that the zipper is not easily deformed after demolding.

[0023] Anti-slip strips 16 are provided on one side of the injection groove of the lower mold 12. Multiple anti-slip particles 17 are provided above the upper mold 15 on the lower end face of each anti-slip strip 16. When the zipper teeth are fixed by injection molding, the anti-slip strips 16 and the anti-slip particles 17 of the upper mold 15 are relatively displaced by the lower mold to form a compression. The anti-slip strips 16 and anti-slip particles 17 will fix the zipper strip and prevent it from shifting during injection molding, which would cause the adhesion between the zipper teeth and the zipper strip to become skewed.

[0024] Furthermore, such as Figure 1 and Figure 6 As shown, a conveyor belt 18 is provided on one side of the first support frame 13 at the upper end face of the workbench 10. A fixed cover 19 is fixedly provided on the side wall of the first support frame 13 above the conveyor belt 18. A cutting roller 20 is rotatably provided inside the fixed cover 19 above the conveyor belt 18. The annular blade on the cutting roller 20 rotates and abuts against the conveying end face of the conveyor belt 18. A support plate 35 is provided below the cutting roller 20 inside the conveyor belt 18. The support plate 35 provides support for the transmission end face of the conveyor belt 18, facilitating the cutting roller 20 to cut the injection molding waste between the zipper teeth on the upper end face of the conveyor belt 18. The position of the annular blade of the cutting roller 20 is exactly between the two rows of zipper teeth after injection molding. A second motor is provided on one side of the cutting roller 20 at the side wall of the fixed cover 19 to drive the cutting roller 20 to rotate. The second motor drives the cutting roller 20 to rotate and cooperate with the conveying end face of the conveyor belt 18 to cut the zipper teeth that have moved to the upper end face of the conveyor belt 18.

[0025] Furthermore, such as Figure 3 and Figure 6 As shown, multiple elastic pressure plates 21 are uniformly arranged in a ring inside the cutting roller 20. During the rotation of the cutting roller 20, the multiple elastic pressure plates 21 rotate with the cutting roller 20. When the elastic pressure plate 21 rotates to the upper end face of the conveyor belt 18, it will form an elastic downward pressure to fix the injection molding waste connected between the chain teeth, thereby ensuring the stable cutting of the waste by the subsequent cutting roller 20. A discharge port 34 is provided on one side of the conveyor belt 18 at the upper end face of the worktable 10. When the waste is cut off, the elastic pressure plate 21 rotates with the cutting roller 20, gets rid of the indirect compression with the conveying end face of the conveyor belt 18 and restores its elastic deformation, thereby forming a downward pressure on the waste generated by the cutting, so that the waste can be discharged smoothly from the discharge port 34.

[0026] Furthermore, such as Figure 3 and Figure 6As shown, each elastic pressure plate 21 has a limiting rod 22 on one side inside the cutting roller 20. The limiting rod 22 limits the elastic deformation of the elastic pressure plate 21, so that the elastic pressure plate 21 and the conveying end face of the conveyor belt 18 have greater elastic downward pressure on the connecting waste between the chain teeth, thereby making the cutting roller 20 cut the waste more stably and producing fewer burrs.

[0027] Furthermore, such as Figure 6 and Figure 7 As shown, detection turntables 23 are fixedly installed on both sides of the cutting roller 20. The diameter of the detection turntables 23 is slightly smaller than the maximum diameter of the cutting roller 20, thereby ensuring that the annular cutting blade of the cutting roller 20 cuts the excess waste of the chain teeth. Multiple grooves 24 are evenly distributed in a double-ring shape on the outer surface of the detection turntables 23. The arc-shaped rotation distance between two adjacent grooves 24 is equal to the distance between two adjacent chain teeth. A pressing slider 25 is slidably installed inside each groove 24. The distance between two grooves 24 is set to ensure that each pressing slider 25 can detect each chain tooth continuously when it rotates with the detection turntable 23. A pressure sensor 26 is installed on one side of the inner bottom surface of the groove 24. The output end of each pressure sensor 26 is elastically abutting against one side wall of the pressing slider 25. The output end of the pressure sensor 26 is elastically set. The chain teeth are detected by the magnitude of the squeezing force of the pressing slider 25, and at the same time, it can also form elastic support on one side of the pressing slider 25.

[0028] After the zipper is injection molded and demolded, the first motor drives the first discharge roller 48 to rotate, creating a horizontal pull on the molded zipper. At the same time, the second motor drives the cutting roller 20 and the detection turntable 23 to rotate. The cutting roller 20 removes waste material between the zipper teeth, and the detection turntable 23 drives multiple pressing sliders 25 to rotate. The rotation speed of the cutting roller 20 and the detection turntable 23 is the same as the horizontal movement speed of the zipper. At the same time, the conveying speed of the conveyor end face of the conveyor belt 18 is also the same as the horizontal movement speed of the zipper, so that each zipper tooth is pressed against its adjacent pressing slider 25. Since the outer surface of each detection turntable 23 is equipped with two annular pressing sliders 25, the multiple pressing sliders 25 near the cutting roller 20 form a squeezing detection on the meshing part of the chain teeth, and the other annular multiple pressing sliders 25 form a squeezing detection on the part where the chain teeth are bonded to the zipper strip. If a missing tooth is detected at the meshing part of the chain teeth, it indicates that the injection flow channel of the chain tooth mold is blocked and needs to be cleaned in time. If a missing tooth is detected at the part where the chain teeth are bonded to the strip, it indicates that the injection pressure is too low, so that the injection cannot fill the injection cavity and the injection pressure needs to be adjusted.

[0029] Furthermore, such as Figure 7 and Figure 8As shown, a fixed turntable 27 is fixedly installed on one side of each detection turntable 23. An annular groove 28 is provided on one side wall of each fixed turntable 27. A sliding groove 29 is provided on one side of each pressing slider 25 on the inner circular surface of the annular groove 28. A pressing strip 30 is slidably installed inside each sliding groove 29. A first spring 31 is connected between each pressing strip 30 and the annular groove 28. Multiple anti-slip protrusions 32 are provided at one end of each pressing strip 30. The fixed turntable 27 drives the multiple pressing strips 30 to follow the cutting roller 20. As the zipper rotates, multiple pressing strips 30, under the elastic tension of the first spring 31 and in conjunction with the conveying end face of the conveyor belt 18, press down and fix the zipper strip on one side of the chain teeth. Furthermore, the multiple anti-slip protrusions 32 provided at one end of each pressing strip 30 make the pressing and fixing of the zipper strip by the pressing strip 30 more secure. This effectively avoids the problem of the zipper on both sides of the cutting roller 20 moving inward due to the downward pressure generated when the cutting roller 20 cuts off the chain tooth waste, thereby ensuring the stability and accuracy of the chain tooth detection by the multiple pressing sliders 25.

[0030] It should be noted that each fixed turntable 27 is provided with a conductive slip ring 33 on one side. The conductive slip ring 33 is a common conductive slip ring, which can ensure that multiple pressure sensors 26 rotate while providing power and signal transmission to multiple pressure sensors 26.

[0031] Example 2: Based on Example 1, further examples are made, such as... Figure 3 and Figure 9 As shown, a fixed frame 36 is provided on one side of the cutting roller 20. Multiple rotating rollers 37 are rotatably arranged inside the fixed frame 36, forming a bottom support for the zipper. A sliding frame 39 is slidably arranged above the multiple rotating rollers 37. Multiple polishing discs 40 are rotatably arranged on the lower end face of the sliding frame 39. A third motor is provided above each polishing disc 40 on the upper end face of the sliding frame 39 to drive the polishing disc 40 to rotate. The third motor drives the polishing disc 40 to rotate, which, together with the multiple rotating rollers 37, forms a polishing and grinding effect on the zipper teeth, thus polishing the burrs generated when the zipper tooth waste is cut off. A second support frame 38 is fixedly arranged above the fixed frame 36 on the outside of the sliding frame 39, and the second support frame 38 is slidably connected to the sliding frame 39.

[0032] Furthermore, such as Figure 9 and Figure 10As shown, a sliding rod 41 is provided on the upper end face of the sliding frame 39. The sliding rod 41 is slidably connected to the second support frame 38. A damping ring 44 is provided at the sliding connection between the second support frame 38 and the sliding rod 41. A second spring 55 is provided on the outside of the sliding rod 41 between the second support frame 38 and the sliding frame 39. A rotating support frame 42 is fixedly provided on the upper end face of the workbench 10 between the fixed frame 36 and the conveyor belt 18. A lever 43 is rotatably provided inside the rotating support frame 42. One end of the lever 43 is rotatably connected to the top of the sliding rod 41, and the other end of the lever 43 is elastically abutting against multiple elastic pressure plates 21.

[0033] After the zipper is formed and demolded, the zipper is horizontally discharged by the rotation of the first discharge roller 48 and the coordination of the second discharge roller 49. The zipper, which has already had its waste material removed, moves horizontally between multiple rotating rollers 37 and the polishing disc 40. At this time, the cutting roller 20 drives multiple elastic pressure plates 21 to rotate. During the rotation, the multiple elastic pressure plates 21 will provide upward elastic support to one end of the lever 43. Through the lever structure between the lever 43 and the rotating support frame 42, the other end of the lever 43 will press down on the sliding rod 41. The sliding rod 41 drives the sliding frame 39 and the polishing disc 40 to move vertically downward, so that the multiple polishing discs 40 polish the zipper teeth. Moreover, the damping ring 44 is used to polish the sliding rod. Under the sliding damping force of the moving rod 41, the sliding rod 41 will drive the sliding frame 39 and other components to form a stable downward pressure for polishing the zipper during the above process. It will not shake up and down due to the elastic tension of the second spring 55. When the zipper is being injection molded, the zipper as a whole is in a stationary state. The multiple elastic pressure plates 21 are in a stationary state along with the cutting roller 20. When there is no upward lifting operation of the lever 43 by the multiple elastic pressure plates 21, the elastic tension of the second spring 55 itself will form an upward elastic pull on the sliding frame 39 and other components, thereby causing the multiple polishing discs 40 to disengage from the zipper, thus avoiding damage to the zipper due to prolonged polishing.

[0034] Example 3: Based on Example 2, further examples are made, such as... Figure 9 As shown, a through hole 45 is provided below the multiple rotating rollers 37 on the inner bottom surface of the fixed frame 36. A vacuum cleaner 46 is provided below the through hole 45 inside the worktable 10. The input end of the vacuum cleaner 46 is connected to the through hole 45. The vacuum cleaner 46 is a common vacuum cleaner, which is the existing technology. The vacuum cleaner 46 can absorb and store the debris generated by grinding and polishing the chain teeth through the through hole 45.

[0035] Example 4: Based on embodiments one to three, further embodiments are made, such as... Figure 3 and Figure 11As shown, a fan 51 is provided on the upper end face of the fixed cover 19. An air guide shroud 50 is fixedly installed above the cutting roller 20 inside the fixed cover 19. The air guide shroud 50 and the fixed cover 19 form a cooling cavity. The output end of the fan 51 is connected to the cooling cavity. Multiple cooling pipes 52 are provided below the output end of the fan 51 inside the fixed cover 19. The fan 51 is a common fan, which is existing technology. The fan 51 blows air into the cooling cavity formed by the air guide shroud 50 and the fixed cover 19. The cooling is then cooled by the cooling pipes 52 inside the cooling cavity. The air inside the cavity is cooled, so that the air blown out from the lower end of the cooling cavity is cold air, which further cools the zipper before it enters between the cutting roller 20 and the conveyor belt 18. A guide plate 53 is provided at the lower end of the fixed cover 19. The guide plate 53 guides part of the air blown out of the cooling cavity, so that part of the air blows towards the cutting roller 20 and multiple elastic pressure plates 21, which cools down the multiple elastic pressure plates 21 and keeps the multiple elastic pressure plates 21 at a low temperature, thereby ensuring their elastic tension.

[0036] Finally, it should be noted that the zipper forming device with detection function of this invention needs to protect the various mechanical structures and related motion logic in this solution. Therefore, it does not elaborate on the various sensors, detectors and driving components required for the actual operation of the various mechanical structures. However, for those skilled in the art, various control systems and electrical connection methods, including various electrical components and driving components, can be completed using conventional technical means. As long as the beneficial effects or the specific actions during the above-mentioned work can be achieved, they can be implemented. This solution does not impose too many restrictions.
