Description

Technical Field

[0001] This utility model relates to the field of zipper manufacturing technology, and in particular to a double-zipper head zipper splicing machine. Background Technology

[0002] A traditional double-zipper zipper includes a zipper belt and two zipper heads mounted on the zipper belt for opening and closing the zipper belt. One end of the zipper belt has a pin and the other end has a top stop. The zipper head has a zipper head body, a cap, and a pull tab. The zipper head body has a zipper passage for the zipper belt to pass through. The two ends of the zipper passage are the zipper opening end and the zipper closing end, respectively. The end of the zipper passage with the larger opening is the open end, and the end with the smaller opening is the closed end. The pull tab is connected to the cap, and the end of the pull tab facing away from the cap has a pull tab opening. During the manufacturing process of this type of double-zipper zipper, workers need to separate the two strips of a zipper from a roll of zipper tape, then insert the two zippers into one strip through a notch at one end of the fabric. After insertion, the worker pulls the two zippers to the pins on the strip, and the pins on the other strip are inserted into the two zippers. Finally, the worker pulls the two zippers upwards a certain distance before installing the next set of zippers. However, this manual zipper installation method is inefficient.

[0003] Therefore, double zipper head threading machines that automatically install two zipper heads onto the zipper belt have appeared on the market, such as the double zipper head threading machine with application number 2019224572443, which includes a frame; a zipper belt conveyor mounted on the frame; a support device movably mounted on the frame for opening the zipper belt; and an upper mold body and a lower mold body mounted on the frame for forming a guide channel when the mold is closed. The lower mold body includes a first lower mold body and a second lower mold body movably mounted on the frame. The first lower mold body is provided with a first guide groove and a first zipper head clamping groove communicating with the first guide groove in sequence along the direction of zipper belt conveying. The first guide groove is trumpet-shaped, and its width is along the zipper belt conveyor belt. The conveyor belt direction narrows, and the first guide groove includes a tooth inlet and a tooth outlet. When a zipper head is placed in the first zipper head clamping groove, the tooth outlet corresponds to the zipper head's inlet. The second lower mold body is sequentially provided with a second zipper head clamping groove and a second guide groove communicating with the second zipper head clamping groove along the conveyor belt direction. The first zipper head clamping groove and the second zipper head clamping groove are symmetrically arranged. A first zipper head conveying device mounted on the frame is used to feed zipper heads one by one into the first zipper head clamping groove. A second zipper head conveying device mounted on the frame is used to feed zipper heads one by one into the second zipper head clamping groove. In application, the first zipper head conveying device conveys the first zipper head into the first zipper head clamping groove, while the second zipper head conveying device conveys the second zipper head into the second zipper head clamping groove. After the zipper head conveying is completed, the first zipper head conveying device and the second zipper head conveying device return to their original positions. The first zipper head and the second zipper head's engaging section (the end of the zipper that engages) are symmetrically positioned close to each other. At this time, the tooth exit section of the first guide groove is aligned with the inlet section of the first zipper head. Then, the first lower mold body and the second lower mold body approach each other under the drive of the cylinder and rise to close with the upper mold body. The support device opens the zipper tape, changing the zipper tape from an engaged state to a separated state. The zipper tape conveyor drives the zipper tape forward. The zipper teeth of the separated zipper tape enter the first guide groove through the tooth inlet section, then enter the inlet section of the first zipper head through the tooth exit section, and finally complete the first zipper head insertion through the engaging section of the first zipper head, while the zipper tape engages again. Because the engaging portions (the ends of the zipper that engage) of the first and second zipper heads are symmetrically positioned close to each other, the zipper tape immediately enters the engaging portion of the second zipper head after engagement. Then, after passing through the inlet portion of the second zipper head and the second guide groove, the zipper tape separates again, completing the insertion of both zipper heads in one operation. When the zipper heads are inserted, the two zipper heads are symmetrically distributed on the zipper tape with their tails facing each other, and the middle portion of the zipper tape is engaged.

[0004] To facilitate the transport of zipper heads, they typically fall at an angle into the first and second zipper head conveying devices via a conveyor channel on the zipper head vibration output plate. Simultaneously, to facilitate the horizontal transport of the zipper heads into the lower mold body, the first and second zipper head conveying devices must be parallel to the lower mold body. This necessitates that the first and second zipper head conveying devices be set parallel during zipper head transport. However, since the angle between the first and second zipper head conveying devices is fixed, the zipper head can easily get stuck in these devices when falling at an angle, preventing effective transport and impacting work efficiency. Furthermore, the zipper heads are inverted and embedded in the first and second zipper head conveying devices. This means that the first and second zipper head conveying devices can only accommodate zipper heads of a single size. If different zipper heads are to be threaded, the entire first and second zipper head conveying devices need to be replaced, which is quite cumbersome. Moreover, when the zipper head is threaded onto the zipper tape, it is embedded in the first and second zipper clamping grooves. If different zipper heads need to be threaded, the entire lower mold body needs to be replaced. The first and second pull tab fixing devices are also installed on the lower mold body, making disassembly quite troublesome. As a result, the overall device cannot accommodate zipper heads of different sizes.

[0005] In view of this, the inventors of this case conducted in-depth research on the problem, which led to the creation of this case. Summary of the Invention

[0006] The purpose of this invention is to provide a double-zipper chain splicing machine to solve the problems of existing double-zipper chain splicing machines, such as the inability to effectively transport zipper heads, affecting work efficiency, and the inability to use zipper heads of different sizes for threading.

The upper end of the swing rod has an extension part that can extend into the zipper tab. The second column is provided with a swing translation device that controls the swing of the swing rod and drives the swing rod to move up and down.

[0010] The inclined plate has a connecting part and an adjusting part, both of which are plate structures and are arranged opposite each other in the front-rear direction. The adjusting part is located on the front side of the connecting part, and the connecting part is connected to the angle switching device. One end face of the pull head conveying channel facing the same side of the connecting part and the adjusting part is recessed with a through groove that allows the pull head to be placed on top and the pull tab to extend downwards. The two grooves form the aforementioned receiving groove. A hinged rotating block protrudes from the side of the adjusting part facing the connecting part and away from the receiving groove. A hinged rotating groove is recessed on the rear side of the hinged rotating block. The front end of the connecting part extends into the hinge rotation groove. The top surface of the hinge rotation block is recessed with a first hinge rotation hole that runs vertically through the top and bottom. The connecting part is recessed with several second hinge rotation holes that can be aligned one-to-one with the first hinge rotation hole at the position corresponding to the first hinge rotation hole. Each second hinge rotation hole runs vertically through the top and bottom and is spaced apart along the front and back direction. The adjusting part is hinged to the connecting part by hinge bolts that pass through the first hinge rotation hole and the second hinge rotation hole in sequence. The hinge rotation block, the first hinge rotation hole and the second hinge rotation hole are the groove width adjusting device mentioned above.

[0011] The top surface of the connecting part and the top surface of the adjusting part are provided with telescopic springs whose two ends are respectively connected to the connecting part and the adjusting part, and the telescopic springs extend in the front-back direction.

[0012] A feeding plate is provided between the vibrating output disc of the pull head and the inclined plate. The feeding plate is inclined downward toward the receiving groove. The inclined plate and the feeding plate are inclined in the same direction. The top surface of the feeding plate is recessed at the position corresponding to the receiving groove to provide a feeding channel for several pull heads to output in an orderly inclined manner. The feeding channel runs through the top and bottom and is open at both ends. The feeding channel is connected to the receiving groove. The feeding channel is the aforementioned pull head conveying channel. On the two inner side walls opposite to each other of the feeding channel, there are protruding guide strips that are set along the extension direction of the feeding plate and extend into the chain passage of the pull head. On the two inner side walls opposite to each other of the front and rear of the receiving groove, there are protruding alignment blocks that correspond one-to-one with the two guide strips and can extend into the chain passage of the pull head.

[0013] The frame is vertically mounted with a vertical plate extending in the left-right direction. Two inclined mounting plates are installed on the vertical plate, facing each other and forming a horn structure that gradually expands from top to bottom. The inclined plate lies horizontally between the feeding plate and the mounting plate in the front-back direction. On the opposite side of the two mounting plates, there is a hinge block that can slide on the mounting plate in the front-back direction via the aforementioned translation drive device. A guide angle block is connected to the mounting plate and is located outside the side of the hinge block facing away from the mounting plate. The two hinge blocks are located between the two guide angle blocks, and the rear side of the guide angle block is recessed with an inclined groove that slopes downward and leads to the bottom surface of the guide angle block. A rotating block is hinged to the hinge block, one end of which is connected to the rear side of the inclined plate, and the other end can slide down along the inclined groove to the bottom surface of the guide angle block, thereby driving the inclined plate to be horizontally positioned. The hinge block, the guide angle block, and the rotating block constitute the aforementioned angle switching device.

[0014] The rotating block has a sliding section, a hinge section, and a connecting section in sequence. The sliding section has a cylindrical structure, and its axis is perpendicular to the mounting plate. The arc surface of the sliding section abuts against the bottom of the inclined sliding groove. The top surface of the hinge block is recessed with a hinge groove into which the hinge section extends. Both the hinge block and the hinge section are recessed with hinge holes that extend through in the front-back direction. A hinge shaft is horizontally arranged in the hinge hole. The connecting section is connected to the rear side of the inclined plate.

[0015] The guide angle block has locking blocks protruding on both sides, which are respectively locked to the top surface of the mounting plate and the bottom surface of the feeding plate. The bottom surface of the guide angle block has a flat surface and an inclined surface. The two inclined surfaces are located between the two flat surfaces. The flat surface extends in the front-back direction, and the inclined surface is inclined upwards away from the flat surface. The sliding section is within the range of the inclined surface.

[0016] A sliding plate is erected on the front side of the vertical plate. The sliding plate is installed on the front side of the vertical plate by means of a lifting and translating device, which can move up and down. Two first columns are erected on the front side of the sliding plate by means of a horizontal translating device, which can slide relative to each other left and right. The lifting and translating device and the horizontal translating device constitute the above-mentioned translation and lifting structure. The first column and the second column are both erected. The two second columns are located between the two first columns, and the lower end of the second column is locked together with the first column. The first column and the second column are spaced apart to the left and right to form a swing gap. The top surface of the first column is recessed with a swing groove that runs through left and right and allows the swing rod to be hinged in it. The swing translating device has a translating cylinder. The translating cylinder is erected on the lower end of the first column. The output end of the translating cylinder extends into the swing gap and is connected to the lower end of the swing rod. The upper end of the swing rod extends into the swing gap range.

[0017] The placement block has a locking part and a placement part. The locking part and the first column are provided with an adjustable mounting structure that allows the locking part to move left and right and to be locked on the first column. The placement part is located on the top surface of the locking part and extends into the swing distance range. The top surface of the placement part is provided with a top block that abuts against the open end face of the zipper head. The side of the placement part facing the second column is recessed with a first groove for placing one end of the cap inside. The top surface of the second column is recessed with a zipper head groove for placing the closed end of the zipper head body. The bottom of the zipper head groove is flush with the top surface of the placement part. The bottom of the zipper head groove is recessed with a second groove for embedding the other end of the cap inside. The second groove and the first groove are arranged opposite each other on the left and right. The zipper head groove and the second groove constitute the aforementioned placement groove.

[0018] The swing arm has an upper hook, a hinge, and a mounting part from top to bottom. The hinge is vertically installed in the swing groove. The upper hook extends into the swing distance, and the top surface of the upper hook is inclined downwards towards the second column. The upper hook is the aforementioned extension part. The mounting part is connected to the translation cylinder. The hinge has an upper moving groove and a lower moving groove that extend through the front-back direction and extend in the up-down direction. The bottom of the upper moving groove is recessed towards the second column with an inclined groove that slopes downwards. The lower moving groove is located below the upper moving groove. Both the upper and lower moving grooves have a connecting shaft that lies horizontally through the first column.

[0019] This novel double-pull-head chain splicing machine, in application, adjusts the width of the receiving slot corresponding to the pull head using a slot width adjustment device. The second column is installed so that the placement slot corresponds to the width of the pull head. The distance between the placement block and the placement slot is adjusted left and right to accommodate the length of the pull head. The pull head conveying channel tilts to output the pull head into the receiving slot of the inclined plate. The translation drive device is activated, and through an angle switching device, the inclined plate is conveyed straight forward until the receiving slot corresponds to the placement slot above the pull head seat. At this point, the pull tab is vertically positioned between the first and second columns. The swing translation device is activated, the swing arm swings, and the upper end of the swing arm hooks the pull tab's opening. The two second columns drive the pull head to move away from the inclined plate, causing the pull head to slide from the receiving slot to the placement slot and placement block. The swing arm pulls down the pull tab, limiting the pull head to the placement slot and placement block. The two second columns move relative to each other, bringing the closed ends of the two pull heads closer together. At this point, the two zipper belts are conveyed to the right, the two belts are spread apart, the two second uprights move horizontally and upward, so that the two zipper heads are positioned between the two belts, and the fabric end notches of the two belts correspond to the chain passage range of the left zipper head. The belt on the rear side moves forward, and the two belts move to the right together. The belt on the rear side enters the rear end of the chain passage of the two zipper heads from left to right through the fabric end notches. The two belts continue to move to the right, so that the two zipper heads are positioned at the pins of the rear belt. The belt on the front side moves to the right and aligns the pins of the front belt with the upper right front end of the chain passage of the right zipper head. Then the belt on the front side moves to the left, so that the pins of the front belt are inserted into the two zipper heads from right to left. The two zipper heads are pulled to the right a certain distance, so that the two belts partially close together, thus completing the installation of one set of zipper belts corresponding to the two zipper heads. After installing several sets of zippers in sequence, they are wound up. Compared with existing technologies, the inclined plate can tilt to receive the slider and horizontally deliver it into the placement slot of the slider holder, enabling the slider to be effectively and straightly conveyed. Furthermore, the slot width adjustment device can adjust the width of the receiving slot accordingly, allowing the inclined plate to receive sliders of different sizes. The placement slot and placement block also enable the slider holder to receive sliders of different sizes, making the entire device more versatile. Moreover, the slider holder only needs to replace the second column to adapt to the processing of sliders of different sizes, making the operation relatively simple. Attached Figure Description

[0027] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.

[0028] A double-head chain splicing machine, such as Figures 1-7 As shown, the device includes a frame 1, a slider holder mounted on the frame for independently placing two sliders, and a slider conveyor for transferring sliders to the slider holder. The slider holder has two slider seats 2 arranged horizontally side by side, with the sliders placed upside down and the slider tabs standing vertically downwards. The slider conveyor has a slider transfer seat and a slider conveying channel 100, one end of which is connected to the slider transfer seat and the other end of which is connected to the slider vibration output disc and is inclined downwards. There are two slider transfer seats and two slider conveying channels 100 respectively. Specifically, the frame has a plate body, and a feeding plate 11 mounted on the plate body is supported below the output end of the slider vibration output disc. The feeding plate 11 is inclined downwards away from the slider vibration output disc, and the top surface of the feeding plate 11 is recessed. There is a feeding channel for the orderly inclined output of several zipper heads. The feeding channel runs vertically through the entire channel and is open at both ends. The extension direction of the feeding channel is consistent with the inclination direction of the feeding plate. The feeding channel is the aforementioned zipper head conveying channel 100. The plate is also equipped with a zipper belt conveying device and a support knife device for opening the zipper belt. The specific structure of the zipper head vibration output disc, which stacks the zipper heads in the zipper head conveying channel 100, with the zipper tabs extending out from below the zipper head conveying channel 100 and outputting the zipper heads in an orderly inclined manner, as well as the zipper belt conveying device and the support knife device for opening the zipper belt, are all technologies known to those skilled in the art. The working principle of this zipper head vibration output disc is the same as that of the discharge vibration disc in the zipper head threading device of application number 2023219603876, and will not be elaborated here.

[0029] The zipper feeder has an inclined plate 3 that extends along the front-rear direction at the same inclination angle as the zipper feeder channel 100. The inclined plate 3 has a receiving groove 200 at the output end of the zipper feeder channel 100 for the zipper head to slide into. The inclined plate 3 is equipped with a groove width adjustment device that can adjust the width of the receiving groove 200 according to the size of the zipper head. Specifically, the inclined plate 3 is in the same inclination direction as the feeding plate 11. The inclined plate 3 has a connecting part 31 and an adjusting part 32, both of which are plate-shaped. The structure includes a connecting part 31 and an adjusting part 32 arranged opposite each other in the front-rear direction. The adjusting part 32 is located on the front side of the connecting part 31. One end face of the pull head conveying channel 100 facing the same side of the connecting part 31 and the adjusting part 32 is recessed with a groove that extends vertically through the pull head and allows the pull tab to be placed on top and extended downward. The two grooves form the receiving groove 200, that is, the opening of the receiving groove 200 on the left side faces left and the opening of the receiving groove on the right side faces right. The adjusting part 32 is designed to allow the relative distance between the two grooves to be adjusted laterally in the front-rear direction. The adjusting part 32 is hinged to the connecting part 31. Specifically, a hinged rotating block 321 protrudes from the side of the adjusting part 32 facing the connecting part and away from the receiving groove. Specifically, the right front end of the adjusting part 32 on the left side protrudes from the right front end, and the left front end of the adjusting part 32 on the right side protrudes from the left front end. A hinged rotating groove is recessed on the rear side of the hinged rotating block 321. A hinged protrusion protrudes from the front end of the connecting part 31 at the position corresponding to the hinged rotating groove. The hinged protrusion extends into the hinged rotating groove. The top surface is recessed with a first hinged rotating hole that extends vertically. The connecting part 31, corresponding to the position of the first hinged rotating hole, has several second hinged rotating holes that can be aligned one-to-one with the first hinged rotating hole. Each second hinged rotating hole extends vertically and is spaced apart along the front-to-back direction. The adjusting part 32 is hinged to the connecting part 31 by hinge bolts 322 that pass through the first hinged rotating hole and one of the second hinged rotating holes in sequence. The first hinged rotating hole, the second hinged rotating hole, and the hinge bolts 322 constitute the aforementioned groove width adjusting device. Preferably, guide strips are protruding from the two opposing inner sidewalls of the feeding channel, extending along the extension direction of the feeding plate 11 and into the chain passage of the pull head. Alignment blocks 323 are protruding from the two opposing inner sidewalls of the receiving groove 200, corresponding one-to-one with the two guide strips and extending into the chain passage of the pull head. In application, the distance between the adjusting part 32 and the connecting part 31 is adjusted so that the width of the receiving groove is adapted to the width of the pull head. The hinge bolt 322 is screwed into the first hinge rotating hole and the second hinge rotating hole respectively, so that the pull head output from the pull head conveying channel 100 can fall into the receiving groove in a straight line, and the alignment block 323 extends into the chain passage so that the pull head can be conveyed in a straight line.

[0030] The frame is equipped with a translation drive device that controls the forward and backward movement of the tilting plate 3. The translation drive device and the tilting plate 3 are equipped with an angle switching device that, as the tilting plate 3 moves, can rotate the tilting plate 3 to a straight position. The connecting part 31 of the tilting plate 3 is connected to the angle switching device. Specifically, a vertical plate 12 extending in the left-right direction is erected on the plate body. Two upwardly inclined mounting plates 121 are mounted on the vertical plate 12, facing each other left and right, forming a horn structure that gradually expands from top to bottom. The tilting plate 3 lies horizontally between the feeding plate 11 and the mounting plates 121 in the front-back direction, and the tilting plate 3 is perpendicular to the mounting plates 121. The mounting plates 121 are configured such that a hinge block 41, which can slide in the front-back direction via the aforementioned translation drive device, is provided on one side facing away from each other. Specifically, the translation drive device includes a translation drive cylinder 13, which extends in the front-back direction on one side of the mounting plates 121, with its output end facing forward. The hinge block 41 is stacked on the top surface of the translation drive cylinder 13. A slide bar extending in the front-back direction is provided on the mounting plate 121 at a position corresponding to the hinge block 41. A slider is slidably engaged with the hinge block 41 at a position corresponding to the slide bar. The front side of the hinge block 41 is locked with a connecting plate 411 connected to the output end of the translation drive cylinder 13. In application, the translation drive cylinder 13 is activated, and the hinge block 41 moves back and forth along the slide bar.

[0031] A guide angle block 42 is connected to the mounting plate 121. The guide angle block 42 is located outside the hinge block 41 on the side facing away from the mounting plate 121. The two hinge blocks 41 are located between the two guide angle blocks 42. The rear side of the guide angle block 42 is recessed with an inclined groove 300 that is inclined downward and leads to the bottom surface of the guide angle block 42. That is, the bottom surface of the guide angle block 42 has a flat surface 421 and an inclined surface 422. The two inclined surfaces 422 are located between the two flat surfaces 421. The flat surface 421 extends in the front-back direction. The inclined surface 422 is inclined upward away from the flat surface 421. The two inclined surfaces form a horn structure that gradually expands from top to bottom. The two sides of the guide angle block 42 are provided with a first locking block 423 and a second locking block 424 that are respectively locked to the top surface of the mounting plate 121 and the bottom surface of the feeding plate 11.

[0032] The hinge block 41 is hinged to a rotating block 43, one end of which is connected to the rear side of the inclined plate 3, and the other end of which can slide down along the inclined slide groove 300 to the bottom surface of the guide angle block 42, thereby driving the inclined plate 3 to be set horizontally. That is, the rotating block 43 has a sliding section 431, a hinge section 432 and a connecting section 433 in sequence. The sliding section 431 has a cylindrical structure, and the axis of the sliding section 431 is perpendicular to the mounting plate 121. The sliding section 431 is located on the inclined surface 4. Within the range of 22, the arc surface of the sliding section 431 abuts against the bottom of the inclined slide groove 300. The top surface of the hinge block 41 is recessed with a hinge groove into which the hinge section 432 extends. Both the hinge block 41 and the hinge section 432 are recessed with hinge holes that extend through in the front-rear direction. A hinge shaft is horizontally arranged in the hinge hole. The connecting section 433 is connected to the rear side of the inclined plate 3. The hinge block 41, the guide angle block 42, and the rotating block 43 constitute the above-mentioned angle switching device. In application, the translation drive cylinder 13 is driven, the hinge block moves forward, and drives the rotating block 43 and the inclined plate 3 to move forward. The sliding section 431 of the rotating block 43 slides down along the inclined slide groove to the bottom surface of the guide angle block 42. The sliding section 431 continues to slide forward along the inclined surface. When the sliding section 431 slides to the inclined surface 422, the inclined plate swings from the inclined upward to a straight state, so that the inclined plate 3 continues to move straight forward to the top of the pull head seat 2. Furthermore, the first locking block 423 and the second locking block 424 enable the guide angle block 42 to more stably guide the rotating block 43 when it is subjected to the force of the sliding section 431.

[0033] The pull head placement seat also has a translational lifting structure that drives the two pull head seats 2 to rise and fall synchronously and move relative to each other. Specifically, a sliding plate 121 is erected on the front side of the vertical plate 12. The sliding plate 121 is installed on the front side of the vertical plate 12 in a way that allows it to move up and down via a lifting and translational device. That is, the front side of the vertical plate 12 is provided with two first slide rails 122 that extend vertically and are spaced apart horizontally. The rear side of the sliding plate 121 is slidably fitted with a first sliding block at the position corresponding to the first slide rails 122. The lifting and translational device has a first drive cylinder 14, which is erected on the bottom surface of the plate body with its output end facing upwards. The two pull-head seats 2 are connected to the sliding plate 121. They are vertically mounted on the front side of the sliding plate 121 via a horizontal translation device, allowing for relative left-right sliding. Specifically, the front side of the sliding plate 121 has a second slide rail 1211 extending in the left-right direction. The rear sides of the two pull-head seats 2 are slidably fitted with second sliding blocks corresponding to the second slide rail. The horizontal translation device has two second drive cylinders 15 arranged opposite each other and extending in the left-right direction on the plate. The output end of each second drive cylinder 15 faces and is connected to the second sliding block on the same side. The lifting and horizontal translation device constitutes the aforementioned translation and lifting structure. In application, the first drive cylinder 14 is activated, causing the sliding plate 121 to move up and down in cooperation with the first slide rail and the first sliding block. The second drive cylinder 15 is activated, causing the two pull-head seats 2 to move relative left-right or opposite to each other in cooperation with the second slide rail and the second sliding block.

[0034] The zipper head base 2 is located below the front side of the inclined plate 3.

If zipper heads of different sizes are processed, the second column 22 is replaced so that the zipper head groove 700 on the second column 22 matches the width of the zipper head, and the second groove matches the size of the cap. Then, the distance between the placement block 5 and the second column 22 is adjusted by adjusting the installation structure so that the open end of the zipper head can be stacked on the placement part 52, so that the zipper head seat 2 is not limited to a single zipper head size.

[0036] A vertically mounted swing rod 6 is hinged inside the first column 21, with its upper end capable of swinging towards the second column 22 and extending between the first and second columns 21. The upper end of the swing rod 6 has an insertion portion that can extend into a pull tab. The second column 22 is provided with a swing translation device for controlling the swing of the swing rod 6. Specifically, the top surface of the first column 21 is recessed with a swing groove that extends through the left and right sides and allows the swing rod 6 to be hinged within it. The swing translation device has a translation cylinder 211, which is vertically mounted on the lower end of the first column 21. The output end of the translation cylinder 211 extends into the swing distance 500 and connects to the lower end of the swing rod 6. The upper end of the swing rod 6 extends into the swing distance 500. That is, the swing rod 6 has an upper hook portion 61, a hinge portion 62, and a mounting portion 63 from top to bottom. The hinge part 62 is vertically installed in the swing groove, and the upper hook part 61 extends into the swing distance. The top surface of the upper hook part 61 is inclined downwards away from the second column 22. The upper hook part 61 is the aforementioned extension part. The mounting part 63 is connected to the output end of the translation cylinder 211. The hinge part 62 is provided with an upper moving groove 800 and a lower moving groove 900 that extend through in the front-back direction and in the vertical direction. The bottom of the upper moving groove 800 is recessed in the direction of the second column 22 and is inclined downwards. The lower moving groove 900 is located below the upper moving groove 800. The vertical length of the upper moving groove 800 is less than the vertical length of the lower moving groove 900. The upper moving groove 800 and the lower moving groove 900 are provided with an upper connecting shaft 212 and a lower connecting shaft 213 that lie horizontally through the first column 21. In the initial state, the output end of the translation cylinder 211 moves downward, the upper connecting shaft 212 is in the bottom of the inclined groove, and the lower connecting shaft 213 is in the bottom of the lower moving groove 900. At this time, the upper hook 61 moves away from the second column 22, causing part of the upper hook 61 to enter the swing groove range. The pull piece falls into the swing distance 500. The translation cylinder 211 is activated, and the output end of the translation cylinder 211 moves upward, causing the upper connecting shaft 212 to slide out of the inclined groove and move upward into the upper moving groove 800. The upper connecting shaft 212 moves upward in the upper moving groove 800 to the top of the upper moving groove 800, and the lower connecting shaft 213 moves upward in the lower moving groove 900 to the top of the lower moving groove 900. The upper hook 61 then enters the swing distance 500 and hooks into the pull opening of the pull piece. The output end of the translation cylinder moves downward, and the upper connecting shaft moves in the upper moving groove 800 to pull the pull piece downward, thus applying force to the pull head.

[0037] In this novel double-pull-head chain splicing machine, the width of the receiving slot corresponding to the pull head is adjusted by the slot width adjustment device. The second column is installed so that the placement slot corresponds to the width of the pull head. The distance between the placement block and the placement slot is adjusted left and right to accommodate the length of the pull head. The pull head conveying channel 100 tilts and outputs the pull head into the receiving slot of the inclined plate 3. The translation drive device is activated, and the rotating block 43 moves forward. The sliding section 431 of the rotating block 43 slides down along the inclined chute to the inclined surface 422 of the bottom of the guide angle block 42, so that the inclined plate 3 is conveyed straight forward until the receiving slot corresponds to the top of the pull head seat. At this time, the pull piece is vertically positioned within the swing distance. The swing translation device is activated, and the swing rod 6 swings. The upper hook 61 of the swing rod hooks the pull opening of the pull piece. The horizontal translation device is activated, driving the two second columns 22 to move away from the inclined plate, causing the pull head to slide from the receiving slot to the placement slot and the placement block. The swing rod pulls down the pull piece, limiting the pull head in the placement slot and the placement block. On the placement block, the two second columns 22 move relative to each other, bringing the closed ends of the two zipper heads closer together. At this time, the two belts of the zipper tape are conveyed to the right, and the spreading device spreads the two belts apart. The two second columns move horizontally and upward, so that the two zipper heads are positioned between the two belts, and the fabric end notches of the two belts correspond to the chain passage range of the left zipper head. The belt on the rear side moves forward, and the two belts move to the right together. The belt on the rear side enters the rear end of the chain passage of the two zipper heads from left to right. The two belts continue to move to the right, so that the two zipper heads are positioned at the pins of the rear belts. The belt on the front side moves to the right, so that the pins of the front belts correspond to the upper right front end of the chain passage of the right zipper head. Then, the belt on the front side moves to the left, so that the pins of the front belts are inserted into the two zipper heads from right to left. The two zipper heads are pulled to the right a certain distance, so that the two belts are partially closed, thus realizing the installation of one set of zipper heads for the zipper tape. After installing several sets of zippers in sequence, they are wound up. Compared with existing technologies, the inclined plate can tilt to receive the slider and deliver it straight to the slider holder's placement slot, ensuring the slider is effectively and straightly transported to the slider holder, avoiding slider clipping and improving production efficiency. Furthermore, the slot width adjustment device can adjust the width of the receiving slot, allowing the inclined plate to receive sliders of different sizes. The placement slot and placement block also enable the slider holder to receive sliders of different sizes, making the entire device more versatile. Moreover, the slider holder only needs to replace the second column to adapt to the processing of sliders of different sizes, making disassembly relatively simple.

[0038] The advantage of this invention is that the top surface of the connecting part 31 and the top surface of the adjusting part 32 are provided with telescopic springs 311, whose two ends are respectively connected to the connecting part 31 and the adjusting part 32. The telescopic springs 311 extend in the front-back direction. In application, when the pull head enters the receiving groove, under the action of the telescopic springs 311, the pull head is limited in the receiving groove with a certain tension, making the pull head less susceptible to scratches from the inclined plate.
