Description

Technical Field

[0001] This utility model relates to the field of zipper manufacturing technology, and in particular to a double-zipper feeder device. 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.

[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. Utility Model Content

[0006] The purpose of this invention is to provide a double-pull-head feeding device to solve the problem that existing double-pull-head devices cannot effectively transport materials and affect work efficiency.

[0007] To achieve its purpose, this utility model adopts the following technical solution:

[0008] A dual-pull-head feeding device includes a frame and a pull-head conveying device mounted on the frame. The pull-head conveying device has a pull-head transfer seat and a pull-head conveying channel with one end connected to the pull-head transfer seat and the other end connected to the pull-head vibration output plate, and is arranged at a downward inclination. Two pull-head transfer seats and two pull-head conveying channels are provided respectively. The pull-head transfer seat has an inclined plate that is inclined at the same angle as the pull-head conveying channel and extends in the front-back direction. The inclined plate has a receiving groove at the output end of the pull-head conveying channel for the pull-head to slide into. The inclined plate has a groove width adjustment device that can adjust the groove width according to the size of the pull-head. A translation drive device that controls the front-back translation of the inclined plate is installed on the frame. The translation drive device and the inclined plate are equipped with an angle switching device that can drive the inclined plate to rotate to a straight state as the inclined plate is translated.

[0009] The inclined plate has a connecting part and an adjusting part, both of which are plate structures. The connecting part and the adjusting part are arranged opposite to each other in the front-back 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 groove that runs vertically through and allows the pull head to be placed on top and the pull tab to extend downward. The two grooves form the aforementioned receiving groove, and the adjusting part is hinged to the connecting part in such a way that the relative distance between the two grooves can be adjusted laterally in the front-back direction.

[0010] The adjusting part is provided with a hinged rotating block on the side facing the connecting part, and the hinged rotating block is positioned away from the receiving groove. The rear side of the hinged rotating block is recessed with a hinged rotating groove. The front end of the connecting part is provided with a hinged protrusion at the position corresponding to the hinged rotating groove. The hinged protrusion extends into the hinged rotating groove. The top surface of the hinged rotating block is recessed with a first hinged rotating hole that extends vertically. The connecting part and the hinged protrusion are recessed with a plurality of second hinged rotating holes at the positions corresponding to the first hinged rotating holes, which can be aligned one-to-one with the first hinged rotating holes. Each second hinged rotating hole extends vertically and is spaced apart in the front-back direction. The adjusting part is hinged to the connecting part by hinge bolts that pass through the first hinged rotating hole and one of the second hinged rotating holes in sequence. The hinged rotating block, the first hinged rotating hole and the second hinged rotating hole are the aforementioned groove width adjusting device.

[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 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 surfaces extend in the front-back direction, and the inclined surfaces are inclined upwards away from the flat surfaces. The sliding section is located within the range of the inclined surfaces.

[0016] 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.

[0017] This novel double-pull-head feeding device, in application, adjusts the width of the receiving groove to correspond to the width of the pull head to be processed via a groove width adjustment device. The pull head is then tilted out of the conveying channel and fed into the receiving groove of the inclined plate. A translation drive device is activated, and through an angle switching device, the inclined plate swings to a straight state, continuing to convey the pull head forward in a straight manner, thus delivering it straight out. Compared with existing technologies, the inclined plate can tilt to receive the pull head and output it straight, ensuring the pull head is in a straight state during feeding, avoiding head clipping, and improving production efficiency. Furthermore, the groove width adjustment device allows for adjustment of the receiving groove width, enabling the inclined plate to accept pull heads of different sizes. Attached Figure Description

[0022] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.

[0023] A double-head feeder device, such as Figures 1-4As shown, the device includes a frame and a pull head conveying device mounted on the frame. The pull head conveying device has a pull head transfer seat and a pull head conveying channel 100, one end of which is connected to the pull head transfer seat and the other end of which is connected to the pull head vibration output plate and is arranged at a downward inclination. Two pull head transfer seats and two pull head conveying channels 100 are respectively provided. Specifically, a feeding plate 1 is attached below the output end of the pull head vibration output plate. The feeding plate 1 is arranged at a downward inclination away from the pull head vibration output plate. The top surface of the feeding plate 1 is recessed to allow several pull heads to tilt in an orderly manner. The feeding channel is inclined and runs vertically through the entire channel with open 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 method of stacking zipper heads on the zipper head conveying channel 100 and having the zipper tabs extend out from below the zipper head conveying channel 100 and outputting the zipper heads in an inclined and orderly manner is a known technology. The working principle of this zipper head vibrating output disc is the same as that of the discharge vibrating disc in the zipper threading device of application number 2023219603876, and will not be elaborated here.

[0024] The zipper feeder has an inclined plate 2 that extends along the front-rear direction at the same inclination angle as the zipper feed channel 100. The inclined plate 2 has a receiving groove 200 at the output end of the zipper feed channel 100 for the zipper to slide into. The inclined plate 2 has a groove width adjustment device that can adjust the width of the receiving groove 200 according to the size of the zipper. Specifically, the inclined plate 2 is in the same inclination direction as the feeding plate 1. The inclined plate 2 has a connecting part 21 and an adjusting part 22, both of which are plate structures. The connecting part 21 and the adjusting part 22 are arranged opposite each other in the front-rear direction. The adjusting part 22 is located on the front side of the connecting part 21. One end face of the pull head conveying channel 100 facing the same side of the connecting part 21 and the adjusting part 22 is recessed with a groove that runs vertically through the connecting part 21 and allows the pull head to be placed on top and the pull tab to extend 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 22 is arranged with the connecting part 21 in such a way that the relative distance between the two grooves can be adjusted laterally in the front-rear direction. The parts are hinged together, meaning that the adjusting part 22 has a hinged rotating block 221 protruding from the side facing the connecting part 21 and away from the receiving groove. Specifically, the right front end of the adjusting part 22 on the left side has a hinged rotating block 221, and the left front end of the adjusting part 22 on the right side has a hinged rotating block 221. A hinged rotating groove extending through the left and right directions is recessed on the rear side of the hinged rotating block 221. A hinged protrusion protrudes from the front end of the connecting part 21 at the position corresponding to the hinged rotating groove, and the hinged protrusion extends into the hinged rotating groove. The hinged rotating block 221... The top surface is recessed with a first hinged rotating hole that extends vertically. The connecting part 21 and the hinged protrusion are recessed with several second hinged rotating holes at positions corresponding to the first hinged rotating hole. These second hinged rotating holes extend vertically and are spaced apart along the front-to-back direction. The adjusting part 22 is hinged to the connecting part 21 by hinge bolts 222 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 bolt 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 1 and into the chain passage of the pull head. Alignment blocks 223 are protruding from the two opposing inner sidewalls of the receiving groove 200, corresponding to the two guide strips and extending into the chain passage of the pull head. In application, the distance between the adjusting part 22 and the connecting part 21 is adjusted so that the width of the receiving groove is adapted to the width of the pull head. The hinge bolt 222 is screwed into the first hinge rotation hole and the second hinge rotation hole respectively, so that the pull head output from the pull head conveying channel 100 can be aligned and fall into the receiving groove. The alignment block 223 extends into the chain passage so that the pull head can be conveyed in the correct position and the pull head is not easy to deviate.

[0025] The frame is equipped with a translation drive device that controls the forward and backward movement of the tilting plate 2. The translation drive device and the tilting plate 2 are equipped with an angle switching device that, as the tilting plate 2 moves, can rotate the tilting plate 2 to a straight position. The connecting part 21 of the tilting plate 2 is connected to the angle switching device. Specifically, the frame has a vertical plate (not shown in the figure) extending in the left-right direction. Two upwardly inclined mounting plates 3 are mounted on the vertical plate, facing each other and forming a horn structure that gradually expands from top to bottom. The tilting plate 2 lies horizontally between the feeding plate 1 and the mounting plates 3 in the front-back direction, and the tilting plate 2 is perpendicular to the mounting plates 3. The mounting plates 3 are arranged in a straight line, with a hinge block 41 on one side facing away from each other. This hinge block 41 can slide in the front-back direction via the aforementioned translation drive device. Specifically, the translation drive device includes a translation drive cylinder 31, which extends in the front-back direction on one side of the two mounting plates 3. The output end of the translation drive cylinder 31 faces forward. The hinge block 41 is stacked on the top surface of the translation drive cylinder 31. A slide bar extending in the front-back direction is provided on the mounting plate 3 at the position corresponding to the hinge block 41. A slider is slidably engaged with the hinge block 41 at the position corresponding to the slide bar. The front side of the hinge block 41 is locked with a connecting plate connected to the output end of the translation drive cylinder 31. In application, the translation drive cylinder 31 is activated, and the hinge block 41 moves back and forth along the slide bar.

[0026] The mounting plate 3 is connected to a guide angle block 42. The guide angle block 42 is located on the side of the hinge block 41 facing away from the mounting plate 3. 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 facing 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 3 and the bottom surface of the feeding plate 1.

[0027] 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 2, 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 2 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 set perpendicular to the mounting plate 3. The sliding section 431 is located on the inclined surface 42. Within the range of 2, 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 2. The hinge block 41, the guide angle block 42, and the rotating block 43 constitute the above-mentioned angle switching device. In application, the driving translation drive cylinder 31 is driven, the hinge block moves forward, and drives the rotating block 43 and the inclined plate 2 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. When the sliding section 431 slides to the inclined surface 422, the inclined plate swings from an inclined position to a straight position, so that the inclined plate 2 continues to be conveyed forward in a straight position. 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.

[0028] This novel double-pull-head feeding device, in application, adjusts the width of the receiving groove to correspond to the width of the pull head to be processed using a groove width adjustment device. The pull head conveying channel 100 tilts and outputs the pull head into the receiving groove of the inclined plate 2. 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 groove to the inclined surface 422 of the bottom surface of the guide angle block 42. The inclined plate 2 swings to a straight state and continues to convey the pull head forward in a straight manner, thus delivering the pull head straight out. Compared with the prior art, the inclined plate can tilt to receive the pull head and deliver it straight into the lower mold body, enabling the pull head to be conveyed effectively and straight, avoiding pull head jamming, and improving production efficiency. Furthermore, the groove width adjustment device can adjust the width of the receiving groove accordingly, allowing the inclined plate to receive pull heads of different sizes.

[0029] The advantage of this invention is that the top surface of the connecting part 21 and the top surface of the adjusting part 22 are provided with telescopic springs 5, whose two ends are respectively connected to the connecting part 21 and the adjusting part 22. The telescopic springs 5 ​​extend in the front-back direction. In application, when the pull head enters the receiving groove, under the action of the telescopic springs 5, 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 2.
