Description

Technical Field

[0001] This utility model relates to the technical field of zipper processing equipment, specifically to a zipper feeder device. Background Technology

[0002] A zipper consists of components such as a fabric tape, teeth, a zipper pull, a top stop, a bottom stop, a tube and socket, a pull tab, and a zipper nose. The fabric tape serves as the base to support the teeth, which open and close by interlocking. The zipper pull controls the closing of the teeth by sliding, the top and bottom stops prevent the zipper pull from falling off, the tube and socket are used to close the open zipper, the pull tab provides convenient operation, and the zipper nose connects the zipper pull and the pull tab.

[0003] A zipper pull attaching machine is an automated assembly device that automatically installs zipper pulls onto zipper tape. For example, patent document CN212877989U discloses a zipper pull attaching machine, which includes a frame, a zipper pull traction device, a zipper splitting device, a zipper pull conveying device, and a zipper pull positioning device. The zipper pull conveying device supplies the zipper pull to the zipper pull positioning device, which then pushes and positions the zipper pull to a designated location (on the zipper's travel path).

[0004] Automotive zippers are special zippers designed for the automotive environment, requiring higher standards in durability, strength, environmental adaptability, and safety. Their zipper pulls are also larger than standard zipper pulls. Currently, there is no specific, stable, and feasible solution for feeding concealed zipper pulls into automotive zippers using existing zipper threading machines. Utility Model Content

[0005] The purpose of this invention is to provide a zipper feeder device to achieve stable feeding of automotive concealed zipper feeders.

[0006] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0007] A puller head feeding device includes a puller head chute, which is equipped with a puller head limiting mechanism and a feeding push plate. The feeding push plate is mounted on a feeding rod, which is rotatably connected to a feeding travel plate via a rotating shaft. The feeding travel plate is equipped with a feeding power device for driving the feeding travel plate along the puller head chute. The feeding rod is equipped with a guide rod, which is equipped with a guide pressure plate. The guide pressure plate has a downward guiding part and a translational guiding part. When the feed head traveling plate drives the guide rod to move along the downward guide section, the feed head rod rotates on the feed head traveling plate along the rotating rod shaft, causing the head end of the feed head push plate to extend into the zipper slide groove. When the feed head traveling plate drives the guide rod to move along the translation guide section, the feed head push plate pushes the zipper head in the zipper slide groove, causing the zipper head to pass through the zipper head limiting mechanism. The feed head rod is provided with a feed head rod reset mechanism, which is used to reset the feed head rod by rotating it along the rotating rod shaft, causing the feed head push plate to disengage from the zipper slide groove.

[0008] The slider limiting mechanism includes a slider limiting block located within a slider limiting block hole and sliding reciprocally along the hole. The slider limiting block is equipped with a limit block return spring, which allows the slider limiting block to extend into the slider slide groove. A feed plate pushes the slider head to slide within the slider slide groove, pressing against the slider limiting block. The slider limiting block retracts into the slider limiting block hole, and after passing the slider limiting block, the slider head slides out of the slider slide groove. Once the slider limiting block is freed from the slider head's pressure, the limit block return spring causes the slider limiting block to automatically protrude out of the inner wall of the slider slide groove. The slider limiting block limits the slider head within the slider slide groove, preventing the slider head from detaching from the slide groove unnecessarily.

[0009] The limiting block hole of the slider is set on the side wall of the slider slide groove.

[0010] The feeder plate is equipped with a feeder guide rail, and the feeder plate reciprocates along the feeder guide rail.

[0011] The feed rod is equipped with a rotating rod, and the rotating rod and the feed push plate are located on the same side of the feed rod. The rotating rod shaft is located on the rotating rod, and the rotating rod rotates on the feed travel plate with the rotating rod shaft as the axis.

[0012] The feed rod reset mechanism is a tension spring, which is disposed between the feed rod and the feed travel plate, and the rotating rod is located between the tension spring and the feed push plate.

[0013] The feed rod is located on the back of the pull head slide groove, and the back of the pull head slide groove is provided with a pull head pushing hole. The feed push plate pushes the pull head in the pull head slide groove within the pull head pushing hole.

[0014] The zipper push hole is equipped with a zipper guide strip, which guides the zipper to continue sliding along the zipper slide groove.

[0015] The feed head push plate is provided with a left push pin and a right push pin at its head end. The left push pin is used to push the left side of the pull head, and the right push pin is used to push the right side of the pull head.

[0016] The vibratory feeder feeds the zipper heads into the zipper head groove in an orderly fashion, arranging them sequentially within the groove. A zipper head limiting block abuts against the front of the zipper head at the end, preventing it from falling out of the groove. The feeder power unit drives the feeder travel plate along the feeder guide rail, and the feeder rod travels along the zipper head groove. When the guide rod reaches the downward pressure guide, the guide presses against it, causing the feeder rod to rotate along the rotating shaft on the zipper travel plate, allowing the feeder pusher plate to extend into the zipper head groove and engage between two adjacent zipper heads. As the guide rod continues to move to the translation guide, the feeder pusher plate pushes the zipper head into the zipper head groove, and the zipper head slides out of the groove after passing the zipper head limiting block. When the feeder travel plate resets, the guide rod, freed from the downward pressure guide, is rotated back to its original position along the rotating shaft by a tension spring, causing the feeder pusher plate to disengage from the zipper groove.

[0017] This invention uses a slider limiting mechanism and a feed pusher plate to push out the sliders one by one from the slider groove, making it easier for downstream devices to receive the sliders and improving the stability of the slider feeding. This invention is not only applicable to the automated feeding of automotive concealed sliders, but also to other sliders. Attached Figure Description

[0024] like Figure 1-5 As shown, a zipper feeder includes a zipper slide 51. A zipper limiting mechanism is provided on the side wall of the zipper slide 51. The zipper limiting mechanism includes a zipper limiting block 92, which is located in a zipper limiting block hole 91 and slides back and forth along the zipper limiting block hole 91. The zipper limiting block hole 91 is provided on the side wall of the zipper slide 51. The head end of the zipper limiting block 92 is arc-shaped and protrudes from the inner wall of the zipper slide 51. A limit block return spring is provided at the tail end 92 of the zipper limiting block. The limit block return spring is used to push the zipper limiting block 92 to slide along the zipper limiting block hole 91, so that the head end of the zipper limiting block hole 91 protrudes from the inner wall of the zipper slide 51. When the slider of the slider slide 51 is subjected to force and passes through the slider limiting block 92, the slider presses against the slider limiting block 92, and the slider limiting block 92 retracts into the slider limiting block hole 91. After the slider passes through the slider limiting block 92, it slides out of the slider slide 51. After the slider limiting block 92 is freed from the pressure of the slider, the limiting block return spring causes the slider limiting block 92 to automatically protrude out of the inner wall of the slider slide 51, blocking the next slider in the slider slide 51.

[0025] A pull head push hole 71 is provided on the back of the pull head slide 51. A pull head guide strip 72 is provided in the pull head push hole 71. The pull head guide strip 72 guides the pull head to continue sliding along the pull head slide 51. The pull head push hole 71 is used for the feed push plate 52 to extend into the pull head slide 51 and push the pull head forward. The head end of the feed push plate 52 is provided with a left push pin and a right push pin. The left push pin is used to extend into the left side of the guide strip 73 to push the left side of the pull head, and the right push pin is used to extend into the right side of the guide strip 73 to push the right side of the pull head.

[0026] The feed push plate 52 is located on one side of the feed rod 53. On the same side of the feed push plate 52, the feed rod 53 is provided with a rotating rod 54. The rotating rod 54 is rotatably connected to the feed travel plate 56 through the rotating rod shaft 55. The rotating rod 54 rotates on the feed travel plate 56 with the rotating rod shaft 55 as the axis, so that the head end of the feed push plate 52 can enter / disengage from the pull head slide groove.

[0027] The feed advance plate 56 is equipped with a feed guide rail 561 and a feed power device 562. The feed guide rail 56 and the pull head slide 51 are arranged in parallel. The feed advance plate 56 slides back and forth along the feed guide rail 561. The feed power device 562 is a cylinder (or other similar power device). When the feed power device 562 drives the feed advance plate 56 to slide back and forth along the feed guide rail 561, the feed push plate 52 and the feed rod 53 reciprocate along the pull head slide 61. A feed rod reset mechanism is provided between the feed rod 53 and the feed advance plate 56. The feed rod reset mechanism is a tension spring (or other similar elastic mechanism). The rotating rod 54 is located between the feed push plate 52 and the tension spring. The tension spring causes the feed push plate to disengage from the pull head slide 61.

[0028] To drive the feed rod 52 to rotate along the rotating shaft 55, causing the feed pusher plate to automatically extend into the pull head groove, a guide rod 58 is provided on one side of the feed rod 53. The guide rod 58 is equipped with a guide pressure plate 59, which has a downward pressure guide portion 591 and a translational guide portion 592. The feed power unit 562 drives the feed travel plate 56 to move the guide rod 58 along the downward pressure guide portion 591. The downward pressure guide portion 591 presses against the guide rod 58, causing the feed rod 53 to rotate along the rotating shaft 55, causing the head end of the feed pusher plate 52 to extend into the pull head pushing hole 71, thus feeding the head... When the head end of the push plate 52 is engaged between adjacent pull heads, the left push pin is located on the left side of the guide bar 73 and the right push pin is located on the right side of the guide bar 73; when the feed head power device 562 drives the feed head traveling plate 56 to move the guide rod 58 along the translation guide part 592, the feed head push plate 52 pushes the pull head to slide in the pull head slide groove 51, and the pull head slides down from the pull head slide groove through the pull head limiting block 91; when the feed head traveling plate 55 is reset, the tension spring causes the feed head rod 53 to rotate and reset around the rotating rod shaft 55, so that the head end of the feed head push plate 52 disengages from the pull head slide groove 51.

[0029] 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.
