Description

Technical Field

[0001] This utility model belongs to the technical field of zipper processing equipment, specifically relating to a double-push chain conveyor mechanism. Background Technology

[0002] A zipper feeder is an automated device used to attach the zipper pull to a zipper, typically integrating feeder and cutting processes. For example, patent document CN109393661B discloses a zipper feeder that includes a feeding mechanism, a chain separating mechanism, a feeder mechanism, a cutting mechanism, a drag chain manipulator, and a conveyor belt assembly. The feeding mechanism includes a chain feeder and a zipper pull feeder. These components are sequentially arranged on a frame along the conveyor direction of the chain. The chain feeder includes a guide wheel on the frame, a base on the frame, a chain slide on the base, and a pressing mechanism on the chain slide. The chain belt slide is slidably mounted on the base, and the sliding direction of the chain belt slide is parallel to the conveying direction of the chain belt to the threading mechanism. The chain belt feeding mechanism also includes a horizontal drive mechanism fixedly mounted on the base for driving the chain belt slide to reciprocate. The pressing mechanism includes a cover plate fixed on the chain belt slide, with a belt conveying gap reserved between the cover plate and the chain belt slide. The belt conveying gap should allow the chain belt to slide freely. The pressing mechanism also includes a pressing telescopic cylinder mounted on the cover plate. The telescopic end of the pressing telescopic cylinder is vertically mounted and points towards the base. The telescopic end of the pressing telescopic cylinder passes through the cover plate and can move freely up and down relative to the cover plate. A pressing block is fixedly mounted on the telescopic end of the pressing telescopic cylinder. The chain belt slide is located at the position farthest from the threading mechanism. The pressing mechanism keeps the chain belt and the chain belt slide relatively fixed. The horizontal telescopic cylinder drives the chain belt to slide towards the threading mechanism until the horizontal drive mechanism reaches the closest position to the threading mechanism, thereby conveying the chain belt to the threading mechanism.

[0003] Automotive zippers are special zippers designed for the automotive environment, requiring higher standards in durability, strength, environmental adaptability, and safety. Automotive zippers have narrower and stiffer chains, and their zipper pulls are larger than standard zipper pulls. When using zipper pull insertion equipment, the chain needs to be inserted into the zipper pull from one side. However, existing zipper pull insertion equipment has the following problems:

[0004] 1. The head end of the chain needs to extend out of the chain pushing mechanism in one go, and the extension distance needs to cross the head-passing mechanism; otherwise, the drag chain robot cannot pull the chain forward from the other side of the head-passing mechanism.

[0005] 2. Although the chain pushing mechanism can reach the closest position to the threading mechanism, there is still a gap between them. This inevitably requires extending the distance of the chain extension and increasing the difficulty of the chain threading into the pull head.

[0006] 3. Although automotive zipper chains are narrow and stiff, they lack rigidity. Longer chains are prone to arching and deforming during the insertion of the zipper pull, affecting the insertion process and potentially causing equipment downtime.

[0007] 4. The chain extends a long distance, and the chain head is prone to deformation and displacement, making it impossible for the chain to pass through the pull tab. Utility Model Content

[0008] To solve the above problems, this utility model provides a double-push chain conveyor mechanism, which can prevent the chain from arching and deforming, and can effectively push the end of the chain into the zipper head, realizing the automatic threading of automotive zippers.

[0009] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0010] A double-push chain conveyor mechanism includes a chain guide plate, a chain guide groove on the chain guide plate, a chain guide cover plate on the chain guide groove, a feed wheel hole on the chain guide cover plate, a feed wheel on the feed wheel hole, and a rotating power device connected to the feed wheel. The rotating power device drives the feed wheel to rotate, and the feed wheel pushes the zipper along the chain guide groove. A pressure rod is provided in the chain guide groove, and a pressure rod is provided with a pressure power device. The pressure power device drives the pressure rod to press the zipper in the chain guide groove. The chain guide plate is provided with a guide rail and a traveling power device, and the traveling power device is used to drive the chain guide plate to travel along the guide rail.

[0011] The zipper is located in the guide groove. The pressing power device drives the pressing rod to press the zipper onto the guide plate. Then, the traveling power device drives the guide plate to move along the guide rail, pulling the zipper to the zipper head (the zipper head is positioned by the zipper head insertion mechanism or other zipper head positioning mechanism), or sending the end of the guide groove to the zipper head. The pressing rod returns to its original position away from the guide plate, allowing the zipper to move within the guide groove. The rotating power device drives the feed wheel to rotate, and the feed wheel pushes the zipper to move within the guide groove, allowing the zipper to pass through the zipper head.

[0012] The chain cover plate is provided with a belt pressing hole, and the belt pressing rod is located at the belt pressing hole.

[0013] The pressure bar is connected to the pressure seat via a pressure bar shaft, and the pressure power device drives the pressure bar to rotate on the pressure seat along the pressure bar shaft. The pressure power device drives the pressure bar to rotate on the pressure seat, causing the pressure bar to press the zipper in the guide groove.

[0014] The pressure bar is rotatably connected to the pressure power device via a chain.

[0015] The feed roller is equipped with a chain feed tooth. The feed roller drives the chain feed tooth to rotate, and the chain feed tooth pushes the chain teeth to make the zipper move along the guide groove.

[0016] The belt feeder includes a first belt feeder and a second belt feeder, and the chain feeder teeth are disposed between the first belt feeder and the second belt feeder.

[0017] The rotational power device is mounted on the feed roller plate, the feed roller plate is provided with a shaft hole through which the feed roller shaft passes, the feed roller shaft is located in the shaft hole, the feed roller is mounted on the feed roller shaft, and the power device drives the feed roller to rotate through the feed roller shaft.

[0018] The feed roller plate is rotatably connected to the feed support plate via the feed roller plate shaft. The feed roller plate is connected to a feed roller displacement power device. The feed roller displacement power device drives the feed roller plate to rotate along the feed roller plate shaft, so that the feed roller presses the zipper onto the chain plate.

[0019] The zipper cover plate is provided with a zipper toothless section positioning mechanism, which includes a positioning hook. The positioning hook is connected to a sensing rod, and the sensing rod is rotatably connected to the positioning hook seat through a sensing rod shaft. The sensing rod is provided with a sensor, which is used to detect the rotation of the sensing rod. The zipper cover plate is provided with a positioning hook hole, and the head end of the positioning hook is located in the positioning hook hole and presses against the zipper in the guide groove.

[0020] The sensing rod is equipped with an elastic component, which causes the head of the positioning hook to press against the zipper.

[0021] This invention first pushes the zipper to the zipper head by the displacement of the chain plate, and then pushes the zipper to continue moving forward a second time by the feed wheel, so as to push the zipper into the zipper head. This not only effectively avoids the problem of the chain arching and deformation, but also effectively pushes the zipper into the zipper head, realizing the automatic threading of automotive zippers.

[0030] like Figure 1-7 As shown, the zipper feed device includes a frame 1, on which a double-push chain conveyor mechanism and a feed mechanism 2 are mounted. The feed mechanism 2 is used to clamp and position the zipper feed, and the double-push chain conveyor mechanism is used to push the zipper onto the feed mechanism 2. It should be noted that how the feed mechanism 3 clamps and positions the zipper feed is existing technology, and its specific structure and principle will not be elaborated here.

[0031] The double-push chain conveyor mechanism includes a chain plate 31. A guide rail mechanism is provided at the bottom of the chain plate 31. The guide rail mechanism includes a guide rail 32 and a slider 33. The guide rail 32 is located at the bottom of the chain plate 31, and the slider 33 is located on a slider seat 11. The slider seat 11 is located on the frame 1. The chain plate 31 is provided with a traveling power device 34. The traveling power device is a cylinder (or other similar power device). The cylinder drives the chain plate 31 to move to the right along the guide rail mechanism.

[0032] A chain guide groove 42 is provided on the chain guide plate 31, and the chain guide groove 42 is set along the left and right direction of the chain guide plate 31. A chain guide cover plate 41 is provided on the chain guide groove 42. The chain guide cover plate 41 is provided with a chain pressing hole 43 and a strip hole 44. The strip hole 44 is set along the chain guide groove 42 and is composed of a feed wheel hole and a positioning hook hole. The positioning hook hole is located between the feed wheel hole and the chain pressing hole 43, that is, the positioning hook is located between the pressure rod 51 and the feed wheel 5. Of course, a chain guide groove 42 can also be provided on the chain guide plate.

[0033] The head end of the pressure rod 51 is located inside the pressure chain hole 43. The pressure rod 51 is connected to the pressure seat 53 via the pressure rod shaft 52. The tail end of the pressure rod 51 is rotatably connected to the chain buckle 54. The chain buckle 54 is rotatably connected to the connecting block 55. The connecting block 55 is connected to the pressure power device 56, which is a cylinder (or other similar power device). The pressure power device 56 is mounted on the chain guide plate 31. The pressure power device 56 drives the pressure plate 51 to rotate on the pressure seat 53 around the pressure rod shaft 52, so that the head end of the pressure rod 51 presses against the zipper in the guide chain groove 42. Alternatively, the pressure rod 51 can be directly connected to the pressure power device 56, which drives the pressure rod downward to press against the zipper in the guide chain groove 42.

[0034] The belt feeder includes a first belt feeder 51 and a second belt feeder 52. A belt feeder gear 5 is provided between the first belt feeder 51 and the second belt feeder 52. On both sides of the belt feeder gear 5, the first belt feeder 51 and the second belt feeder 52 are respectively provided with belt feeder guide grooves. The feeding gear 5, the first feeding wheel 51, and the second feeding wheel 52 are each provided with three connecting positioning pin holes. Positioning pins 53 are provided in the positioning pin holes. Positioning pins 53 connect the first feeding wheel 51 and the feeding gear 5 to the second feeding wheel 52. The second feeding wheel 53 is connected to the feeding wheel shaft 61. The feeding wheel plate 62 is connected to the rotating power device 63, which is a motor (or servo motor or other similar power device). The rotating power device 63 is set on the feeding wheel plate 62. The feeding wheel plate 62 is provided with a shaft hole through which the feeding wheel shaft 61 passes. The feeding wheel shaft 61 is located in the shaft hole. The rotating power device 63 and the feeding wheel are respectively located on both sides of the feeding wheel plate 62. The rotating power device 63 drives the feeding wheel shaft 61 to rotate. The feeding wheel shaft 61 drives the feeding wheel to rotate. The feeding gear 5 pushes the chain teeth 91, so that the zipper moves along the guide groove 42.

[0035] The feed roller plate 62 is rotatably connected to the feed support plate 72 via the feed roller plate shaft 71. The feed support plate 72 is connected to the frame 1. The feed roller plate 62 is connected to a feed roller displacement power mechanism, which is a cylinder 74 (or other similar power device). The cylinder 74 drives the feed roller plate 62 to rotate on the feed support plate 72 around the feed roller plate shaft 71, thereby driving the feed gear 5 to press the zipper in the guide groove. Specifically, the tail end of the cylinder 74 is rotatably connected to the feed support plate 72 via the support plate shaft 73. The piston rod of the cylinder 74 is connected to the feed roller plate connecting block 75, and the feed roller plate connecting block 75 is rotatably connected to the feed roller plate 62 via the feed roller plate shaft 76.

[0036] Zipper 9 is located in the guide groove 42. The pressing power device 56 drives the pressing rod 51 to press the zipper 9 in the guide groove 42. The traveling power device 34 drives the chain plate 31 to move to the right along the guide rail, pushing the zipper 9 to the zipper head of the threading mechanism 3. The pressing power device 56 drives the pressing rod 51 to release the zipper. The rotating power device 63 drives the feeding gear 5 to rotate. The feeding gear 5 pushes the chain teeth 91, and the zipper 9 continues to move to the right along the guide groove 42, and the zipper is threaded into the zipper head.

[0037] The zipper toothless section positioning mechanism includes a positioning hook 81, which presses against the zipper in the guide groove 42 through a positioning hook hole. The positioning hook 81 is connected to a sensing rod 82, which is rotatably connected to a positioning hook seat 84 via a sensing rod shaft 83. The sensing rod 82 rotates on the positioning hook seat 84 about the sensing rod shaft 83. The sensing rod 82 is equipped with a spring (or other similar elastic component), which presses the head of the positioning hook 81 against the zipper in the guide groove 42. The sensing rod 82 is equipped with a sensor 85, which detects the rotation of the sensing rod 82. The head of the positioning hook 81 presses against the zipper teeth. When the toothless section 92 of the zipper belt travels to the positioning hook 81, the positioning hook 81 lacks the support of the zipper teeth 91. The sensing rod 82 rotates on the positioning hook seat 82 with the sensing rod pivot 83 as the axis. The sensor 85 detects the rotation of the sensing rod 82 to position the toothless section 92 of the zipper.

[0038] Of course, the positions of the zipper toothless section positioning mechanism, the pressure rod, and the feed roller are not limited to those used in this embodiment, and their order can be adjusted according to the available space in the equipment. Alternatively, the zipper toothless section positioning mechanism may not be located on the zipper cover plate 41; it only needs to be able to position the toothless end of the zipper. Similarly, the pressure rod 51 may not be located on the zipper cover plate; it only needs to be able to fix the zipper belt to the zipper cover plate.

[0039] The above embodiments do not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
