Description

Technical Field

[0001] This utility model belongs to the technical field of zipper production and processing equipment, specifically relating to a fully automatic nylon zipper double top stop machine. Background Technology

[0002] A zipper consists of two fabric strips (left and right strips), with sequentially spaced teeth installed on the inner edges of each strip, and a top stop at the same end of both strips. During zipper manufacturing, the two strips form a zipper belt structure, both strips equipped with teeth that mesh with each other. The zipper belt itself is composed of sequentially spaced zipper units, with gaps between adjacent units (the gaps represent the areas without teeth). The zipper belt is ultimately cut by a cutting spindle to form individual zippers.

[0003] It should be noted that in existing technologies, automated equipment is generally used to install the zipper chain stop. However, in existing automated stop installation equipment, the stop stamping assembly may not properly press the fabric tape on both sides of the stop area during installation. This results in inaccurate positioning, causing the zipper stop to twist or skew, leading to poor and inconsistent product quality. Furthermore, existing stop installation equipment often uses hydraulic drive for stop installation, resulting in relatively low transmission efficiency and accuracy. Utility Model Content

[0021] Beneficial effects:

[0022] This utility model discloses a fully automatic nylon zipper double top stop machine. The zipper enters the chain belt positioning component through the chain belt feeding device, flattens the zipper tape, and transports the zipper to the stop position. The feeding component transports the required top stop material on both sides of the zipper. The top stop stamping component compresses the top stop material on both sides to complete the top stop operation. Finally, the completed zipper sample is transported to the designated position by the chain belt traction component. The top stop stamping component has a high-precision screw drive mechanism, which can accurately move the zipper to the stop position and reduce positional deviation. In addition, the large support plate in the top stop stamping component presses the tape on both sides of the top stop position, which ensures accurate pressing position and prevents the top stop of the zipper from twisting or skewing, thus resulting in high and stable product quality.

Detailed Implementation

[0038] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0039] The technical solution of this utility model will be described in detail below with specific embodiments.

[0040] refer to Figure 1-13 The present invention relates to a fully automatic nylon zipper double top stop machine, comprising a chain belt feeding device 2, a chain belt positioning component 3, a top stop punching component 4, a feeding component 5, a chain belt traction component 6 for pulling the chain belt, and a sensing mechanism 7 arranged sequentially along the chain belt conveying direction.

[0041] The upper stop stamping assembly 4 includes: a frame 411, a drive motor 413 mounted on the frame 411, a screw transmission mechanism 414 connected to the drive motor 413, a sliding assembly 415 mounted on the screw transmission mechanism 414, a large support plate 416 movably connected to one side of the sliding assembly 415, and a pressure belt lifting assembly 417 mounted on one side of the large support plate 416. The upper stop stamping assembly 4 is used to stamp and form an upper stop. The sliding assembly 415 includes an upper sliding component 418 and a lower cutting component 419. The upper sliding component 418 can drive the large support plate 416 to move synchronously and can move in a staggered manner with the large support plate 416. The lower cutting component 419 is connected to the large support plate 416 and moves synchronously.

[0042] The chain positioning component 3 is located below the belt pressing and lifting component 417. The chain positioning component 3 is used to cooperate with the sliding component 415 to form an upper stop on the inner side of the chain.

[0043] The feeding assembly 5 is disposed on both sides of the chain belt, and the feeding assembly 5 is used to transport the upper stop material 8 to the lower part of the sliding assembly 415.

[0044] Specifically, a frame 411 is installed on the electrical cabinet 1. A motor mounting base 412 is provided on the upper end of the frame 411. A drive motor 413 is provided on the upper end of the motor mounting base 412. A protective cover 4110 is provided on the lower end of the motor mounting base 412. The protective cover 4110 is detachably connected to the frame 411 and has a dustproof function, which reduces the contamination of the upper stop pressing assembly 4 by dust. In use, the pressing belt lifting assembly 417 presses the outer area of ​​the zipper tape, driving... The motor 413 drives the lead screw transmission mechanism 414 to drive the sliding component 415 to achieve two stages of movement. The first stage of movement is that the sliding component 415 drives the large support plate 416 to move synchronously, that is, the sliding component 415 drives the large support plate 416 to press the inner area of ​​the zipper tape. The second stage of movement is that the upper sliding component 418 moves in a staggered manner with the large support plate 416, while the lower cutting component 419 always remains connected to the large support plate 416 and moves synchronously. That is, the sliding component 415 cooperates with the chain positioning component 3 to complete the stopping work.

[0045] In this embodiment, as Figure 4As shown, the upper sliding assembly 415 includes: a nut seat 4151 that moves in conjunction with the lead screw 4141 in the lead screw transmission mechanism 414; a connecting slide 4152 mounted on the nut seat 4151; a slider support 4153 connected to the outside of the connecting slide 4152; a spring base 4158 connected to one side of the connecting slide 4152; and a sliding plate 4159 connected to the other side of the connecting slide 4152. A first chamber 4154 is formed between the connecting slide 4152 and the slider support 4153, and a first spring 4155 is disposed in the first chamber 4154. One end of the first spring 4155 abuts against the spring base 4158, and the other end of the first spring 4155 is provided with a telescopic slider 4156. A pulley 4157 is provided on the outer side of the telescopic slider 4156. The slide plate 4159 is provided with a through hole 41590 for the telescopic slider 4156 to pass through. The slider support 4153 and the connecting slide 4152 are used to limit and support the telescopic slider 4156. The telescopic slider 4156 can move horizontally on the connecting slide 4152 so that one end of the telescopic slider 4156 can enter or leave the through hole 41590.

[0046] Specifically, during the first stage of movement, the first spring 4155 does not undergo significant elastic change. During the second stage of movement, the first spring 4155 undergoes significant elastic change, i.e., the area of ​​the telescopic slider 4156 extending into the first chamber 4154 increases. The end of the connecting slide block 4152 is provided with a groove (not shown in the figure) that abuts against the telescopic slider 4156 to prevent the telescopic slider 4156 from shifting. The slider support 4153 supports the telescopic slider 4156.

[0047] In this embodiment, as Figure 5 and Figure 6 As shown, the large tray 416 has a second chamber 4161 and a third chamber 4162. The third chamber 4162 is equipped with a second spring 4163. The telescopic slider 4156 passes through the through hole 41590 and abuts against the second chamber 4161. The slide plate 4159 is equipped with a first slider 41591. The first slider 41591 is installed in the third chamber 4162 and abuts against the second spring 4163. The sliding assembly 415 drives the large tray 416 to press against the area near the inside of the zipper tape. Figure 4-6As shown, the sliding component 415 achieves the zipper-stopping process in two stages. In the first stage, the telescopic slider 4156 abuts against the second chamber 4161, causing the large support plate 416 to move downward. At this time, the first slider 41591 and the second spring 4163 do not produce significant deformation. When the telescopic slider 4156 compresses the first spring 4155 and leaves the second chamber 4161, the slide plate 4159 and the large support plate 416 disengage. Since the telescopic slider 4156 disengages from the second chamber 4161, the large support plate 416 and the lower cutting component 419 remain stationary. The first slider 41591 compresses the second spring 4163, producing significant deformation. The slide plate 4159 continues to move downward under the drive of the screw transmission mechanism 414, completing the second stage of movement and achieving the zipper-stopping function.

[0048] In this embodiment, the bottom of the sliding plate 4159 is provided with a first protrusion 41593 and a telescopic rod 41592 that cooperates with the lower cutting component 419. The first protrusion 41593 is used to limit the stroke of the telescopic rod 41592. The lower cutting component 419 is provided with a telescopic channel 41594 for the telescopic rod 41592 to pass through, and the bottom of the lower cutting component 419 is provided with an opening groove 41595. Figure 7 and Figure 8 As shown, in the first phase of movement, the lower cutting component 419 moves to the point where it just abuts against the lower die base 321, thus cutting off the upper stop material 8, which remains in the telescopic channel 41594. In the second phase of movement, the telescopic rod 41592 continues to move downward, compressing the upper stop material 8 remaining in the telescopic channel 41594, until the lower die 3212 moves. The telescopic rod 41592 and the lower die 3212 cooperate to complete the upper stop of the zipper. The travel distance of the telescopic rod 41592 to the lower die 3212 is the same as the travel distance from the first protrusion 41593 to the lower cutting component 419.

[0049] In this embodiment, the frame 411 is provided with a first upright plate 4111 adapted to the sliding assembly 415. The first upright plate 4111 is provided with a guide block 4112, and the pulley 4157 can abut against the guide block 4112. The first upright plate 4111 is provided with a telescopic spring seat 4113, and the bottom of the first upright plate 4111 is provided with a base plate 4114. The base plate 4114 is provided with a telescopic seat 4115, and one end of the telescopic seat 4115 abuts against the telescopic spring seat 4113 through a third spring 4116.

[0050] In this embodiment, the other end of the telescopic seat 4115 is provided with a second protrusion 4117 and a protrusion 4118 that cooperates with the opening groove 41595. The second protrusion 4117 is used to cooperate with the lower cutting component 419 to cut the upper stop material 8. Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, during the first stage of the stop movement, the pulley 4157 abuts against the first upright plate 4111, and the telescopic slider 4156 abuts against the second chamber 4161, driving the large support plate 416 downwards. When the pulley 4157 gradually abuts against the guide block 4112, the telescopic slider 4156 compresses the second spring 4163, which is the second stage of the stop movement of the sliding assembly 415. Preferably, the protrusion 4118 is provided with an inclined surface that cooperates with the opening groove 41595. During the second stage of the movement, the lower cutting component 419 and the telescopic seat 4115 gradually abut against each other, effectively reducing the possibility of direct wear between their surfaces. Furthermore, the side end of the lower cutting component 419 cooperates with the opening end of the opening groove 41595 on the second protrusion 4117 to cut the upper stop material 8.

[0051] In this embodiment, the chain positioning component 3 includes a positioning mechanism 31 and a chain splitting mechanism 32 arranged sequentially along the direction from the inlet to the outlet;

[0052] The positioning mechanism 31 includes a zipper plate 311 with a transport zipper. The lower end of the zipper plate 311 is provided with a positioning fixing seat 314. The bottom of the positioning fixing seat 314 is provided with a positioning drive device 315. The piston rod extension of the positioning drive device 315 is provided with a positioning slider seat 316. The positioning slider seat 316 is provided with a groove 317. The outside of the positioning slider seat 316 is provided with a T-shaped push rod 318 connected by a fourth spring 3161. The protruding part of the T-shaped push rod 318 is embedded in the groove 317. The groove 317 is provided with a positioning hook 319 along the zipper output direction. The positioning hook 319 can pass through the zipper plate 311 to separate the zipper to be top-stopped from the zipper with bottom-stopped. The positioning hook 319 is used to position the top-stopped position.

[0053] The chain splitting mechanism 32 includes a lower die base 321 that cooperates with the chain guide plate 311. The lower die base 321 has a positioning groove 320 on one side that is adapted to the positioning hook 319. The lower end of the lower die base 321 is provided with a chain splitting drive device 3211. The lower die base 321 is provided with a splitting tail needle 322 for inserting into the gap between the last pair of chain teeth to separate the chain. The splitting tail needle 322 is driven and connected to the chain splitting drive device 3211. The upper end of the lower die base 321 is detachably provided with a lower concave die 3212, which cooperates with the telescopic rod 41592.

[0054] like Figure 10 and Figure 11 As shown, the pressure plate 312 is used to press the zipper tape output by the zipper tape feeding device 2. The position of the pressure plate 312 can be adjusted by the cooperation between the pin (not shown in the figure) on the pressure plate 312 and the slide groove (not shown in the figure) on the pressure plate adjusting seat 313. When the zipper to be stopped reaches the stop position, the positioning drive device 315 first pushes the positioning slider seat 316 to move upward so that the positioning hook 319 passes through the zipper. Then, the T-shaped push rod 318 pushes the positioning hook 319 to move along the positioning groove 320. At this time, the conveyor belt stops conveying, and the positioning hook 319 abuts against the zipper to be stopped. The lower stop of the adjacent zipper, i.e., the area from the upper stop position of the zipper to be top-stopped to the lower stop position of the adjacent zipper, separates the zipper to be top-stopped from the zipper with its lower stop already set. The positioning hook also serves to position the zipper to be top-stopped at the designated location. The chain-splitting drive device 3211 pushes the splitting pin 322 through the chain and inserts it into the gap between the last pair of chain teeth to separate the chain. After the sliding component 415 moves the large support plate 416 to the upper surface of the lower mold base 321, the telescopic rod 41592 continues its downward compression movement, cooperating with the lower die 3212 to complete the top-stopping of the zipper. Preferably, the hook and hook body of the positioning hook 319, and the lower die 3212 and lower mold base 321 are all detachably connected for easy maintenance and repair.

[0055] In this embodiment, as Figure 9As shown, the pressing belt lifting assembly 417 includes a pressing head 4171 and a pressing rod 4172. The pressing rod 4172 connected to the pressing head 4171 abuts against the large support plate 416. The pressing rod 4172 extends away from the large support plate 416 and is provided with a pressing belt connector 4173. The pressing belt connector 4173 is equipped with a pressing belt drive device 4174. The pressing belt lifting assembly 417 is used to press the area near the outer side of the zipper tape. Preferably, the pressing head 4171 is hollow. The outer side of the pressing head 4171 is used to press the zipper tape, while the hollow part allows the telescopic rod 41592 and the lower cutting component 419 to extend in and complete the top stop operation. This ensures accurate pressing position and prevents the top stop of the zipper from twisting or skewing, thereby resulting in high and stable product quality.

[0056] In this embodiment, as Figure 1 , Figure 2 and Figure 11 As shown, the sensing mechanism 7 includes a first sensing mechanism 71, a second sensing mechanism 72, and a sensing plate 73; the lower mold base 321 is provided with the first sensing mechanism 71 along the tape exit, and the first sensing mechanism 71 is used to control the positioning hook 319 and the tail needle 322; the second sensing mechanism 72 is disposed on the pressure rod 4172 and located above the zipper tape, and the second sensing mechanism 72 is used to control the pressure lifting assembly 417; the nut seat 4151 is provided with a sensing plate 73, and the sensing plate 73 is used to limit the stroke of the lead screw 4141. During the zipper conveying process, when the first sensing mechanism 71 senses the zipper pull, the conveyor belt speed slows down, and the positioning drive device 315 drives the positioning hook 319 to move. When the positioning hook 319 contacts the bottom stop of the zipper to be stopped, the conveyor belt pauses conveying, and the dividing tail needle 322 moves upward. At the same time as the dividing tail needle 322 moves upward, the second sensing mechanism 72 controls the belt pressing and lifting assembly 417 to press down the zipper tape, and the lead screw 4141 drives the sliding assembly 415 to move downward according to the preset stroke of the sensing plate 73 to stop the zipper. After the zipper is stopped, the positioning hook 319 first resets, and then the belt pressing and lifting assembly 417 and the lead screw 4141 reset, and the conveyor belt continues to run, repeating the above steps.

[0057] In this embodiment, as Figure 7 , Figure 8 and Figure 12As shown, the feeding assembly 5 includes an outer cutter 51, a wire feeding mechanism 52, and a feeding drive device 53 arranged sequentially along the outward extension direction. The upper stop material 8 passes through the wire feeding mechanism 52 in sequence and abuts against the protrusion 4118. The wire feeding mechanism 52 includes a wire feeding base 521 mounted on the frame 411. The wire feeding base 521 is arranged sequentially along the outward extension direction with a guide seat 5211, a wire feeding limit seat 5212, a feeding mold 5213, and a feeding limit mold 5214. During the feeding process, the feeding drive device 53 drives the feeding mold 5213 and the feeding limit mold 5214 to reciprocate and convey the upper stop material 8 to abut against the protrusion 4118.
