Description

Technical Field

[0001] This utility model relates to a three-in-one machine for nylon zippers, and more specifically to a three-in-one machine for closing the tail of nylon zippers. Background Technology

[0002] A zipper consists of two zipper straps, a slider, and corresponding teeth on the zipper straps. Depending on the application, the top and bottom ends of the zipper straps can be equipped with top and bottom stops. Zippers are also classified by material, including metal zippers, nylon zippers, and resin zippers.

[0003] In related technologies, the production process of nylon zippers includes cutting, threading, and stopping. However, in existing equipment, each process is basically carried out separately by different machines, which is cumbersome and has low production efficiency.

[0004] Therefore, the existing technology includes a patent with patent number 201910768326.1, entitled "Nylon Zipper Three-in-One Machine," which uses a cutting device, a threading device, and a closing device to cut, thread, and weld the zipper tape. However, this device cuts the zipper tape and then uses a clamping device to hold the cut tape before threading and welding it. Since some nylon zippers require a closing process, the above method cannot close the cut end of the zipper tape due to the subsequent welding process. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a three-in-one machine for closing the end of a nylon zipper.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a three-in-one machine for closing the tail of a nylon zipper, comprising a frame and a feeding device, a cutting device, a threading device, a tail-closing device, and a discharging device arranged sequentially on the frame. The zipper tape is fed in by the feeding device, then cut by the cutting device, then threaded through the threading device, and finally assembled with the tail-closing device. The machine is then discharged through the discharging device. The machine is characterized by further including a turning device, which is arranged between the cutting device and the threading device to turn the zipper tape cut by the cutting device and feed it into the threading device for threading. Then, the end of the zipper tape is fed into the tail-closing device for tail-closing processing.

[0007] As a further improvement of this utility model, the rotating head device includes a rotating head base, a rotating head rod, and two zipper tape clamps. The rotating head base is fixedly installed on the frame, and the middle part of the rotating head rod is rotatably installed on the rotating head base. The two ends of the rotating head rod are respectively close to the cutting device and the threading device. The two zipper tape clamps are respectively installed at the two ends of the rotating head rod to receive the zipper tape after clamping it, and then switch the relative zipper tape clamps to the cutting device and the threading device by rotating the rotating head rod.

[0008] As a further improvement of this utility model, the zipper belt clamp includes a lower rotating plate and an upper rotating plate, as well as a connecting plate. The lower rotating plate and the upper rotating plate are spaced apart from each other, forming a clamping space between them for inserting the zipper belt. Both the lower rotating plate and the upper rotating plate are mounted on the connecting plate and are installed on the end of the rotating rod through the connecting plate.

[0009] As a further improvement of this utility model, a number of connecting columns are fixed on the plate surface of one side of the connecting upright plate. The ends of the connecting columns facing away from the connecting upright plate pass through the upper pressure plate of the rotating head and are fixed on the lower pressure plate of the rotating head. An elastic compression rod is fixed on the side of the lower pressure plate of the rotating head facing the upper pressure plate of the rotating head.

A positioning cylinder is fixed on the cylinder connecting block. The cylinder body of the positioning cylinder is fixedly installed on the cylinder connecting block. The push rod passes through the rotating head pressure plate and extends into the clamping space to position the zipper tape in the clamping space.

[0011] As a further improvement of this utility model, the rotating head device also includes a hook mechanism, which includes a lifting cylinder, a push hook cylinder, and a hook needle. The cylinder body of the lifting cylinder is fixed at one end of the frame near the rotating head rod. The cylinder body of the push hook cylinder is fixedly installed on the push rod of the lifting cylinder so as to be driven up and down by the lifting cylinder. The hook needle is fixedly installed on the push rod of the push hook cylinder. A hook groove is provided at one end of the upper and lower pressure plates of the rotating head. The hook groove clamping space is connected so that the hook needle can penetrate into the hook groove and hook the zipper tape in the clamping space.

[0012] As a further improvement of this utility model, the tail-closing device includes a monofilament feeding mechanism, an ultrasonic tooth-melting mechanism, and a discharge mechanism. The monofilament feeding mechanism is used to output nylon monofilaments to the ultrasonic tooth-melting mechanism. The ultrasonic tooth-melting mechanism receives the end of the zipper tape after threading, and after molding and closing the end of the zipper tape, it is sent out through the discharge mechanism.

[0013] As a further improvement of this utility model, the monofilament feeding mechanism includes a monofilament spool, a wire feeding assembly, and a cutting assembly. The monofilament spool is rotatably arranged on the side of the ultrasonic tooth melting mechanism. The wire feeding assembly and the cutting assembly are arranged sequentially below the monofilament spool. After the nylon wire is pulled out from the monofilament spool, it passes downward through the wire feeding assembly and is fed into the cutting assembly. After being cut by the cutting assembly, it is fed into the ultrasonic tooth melting mechanism.

[0014] As a further improvement of this utility model, the yarn feeding assembly includes upper and lower cylinders, a clamping cylinder, and a yarn feeding seat.

A yarn feeding plate is fixed on one side of the yarn feeding seat. The yarn feeding plate has a channel for nylon yarn to pass through. The cylinder body of the clamping cylinder is fixed on the yarn feeding seat. The side of the yarn feeding plate facing the clamping cylinder has a clamping hole communicating with the channel. The push rod of the clamping cylinder can extend into the clamping hole to position or release the nylon yarn in the channel.

[0015] As a further improvement of this utility model, the ultrasonic tooth melting mechanism includes an upper tooth melting mold and a lower tooth melting mold, as well as a pressing assembly. The upper tooth melting mold is vertically movable and positioned above the lower tooth melting mold, forming a tooth melting space between them for the end of the zipper tape to be inserted. The pressing assembly is installed near the tooth melting space to press down the zipper tape with the end already inserted.

[0016] The beneficial effect of this utility model is that, through the setting of the rotating head device, the zipper tape cut by the cutting device can be effectively rotated. Then, through the action of the subsequent translational clamp, the end of the zipper tape can be sent into the closing device, thus achieving the closing operation of the zipper tape simply and effectively. Compared with the existing technology, it can perform the closing process much better. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0026] Reference Figures 1 to 8 As shown in this embodiment, a three-in-one nylon zipper closing device includes a frame 1 and a feeding device 2, a cutting device 3, a threading device 4, a closing device 5, and a discharging device 6 arranged sequentially on the frame 1. The zipper tape is fed in by the feeding device 2, then cut by the cutting device 3, then threaded through the threading device 4, and finally assembled with the closing device 5. The zipper tape is then discharged through the discharging device 6. The key feature is that it also includes a rotating device 7, which is positioned between the cutting device 3 and the threading device 4 to cut the zipper tape. After the zipper tape is cut, it is rotated and fed into the threading device 4 for threading. Then, the end of the zipper tape is fed into the closing device 5 to close the zipper tape. In this way, the rotating device 7 can effectively realize the rotation operation of the cut zipper tape. Compared with the method in the prior art, the closing device 5 can effectively realize the closing of the zipper tape. In this embodiment, after the zipper tape is cut by the cutting device, it is mainly transported by the existing translational clamp, so it will not be described in detail in this embodiment.

[0027] As an improved specific implementation, the rotating head device 7 includes a rotating head base 71, a rotating head rod 72, and two zipper tape clamps 73. The rotating head base 71 is fixedly installed on the frame 1. The middle part of the rotating head rod 72 is rotatably installed on the rotating head base 71. The two ends of the rotating head rod 72 are respectively close to the cutting device 3 and the threading device 4. The two zipper tape clamps 73 are respectively installed at the two ends of the rotating head rod 72 to receive the zipper tape and then switch the zipper tape clamps 73 relative to the cutting device 3 and the threading device 4 by rotating the rotating head rod 72. By setting the zipper tape clamps 73, the cut zipper tape can be effectively clamped and then the zipper tape can be driven to rotate. The design of two zipper tape clamps 73 can realize that while the zipper tape clamp 73 facing the cutting device 3 receives the cut zipper tape, it can also transfer the zipper tape originally clamped at the other end to the threading device 4 for threading by moving the clamp, thus greatly increasing the rotating head efficiency.

[0028] As an improved specific implementation, the zipper tape clamp 73 includes a rotating head lower pressure plate 731, a rotating head upper pressure plate 732, and a connecting upright plate 733. The rotating head lower pressure plate 731 and the rotating head upper pressure plate 732 are spaced apart from each other, forming a clamping space for inserting the zipper tape. The rotating head lower pressure plate 731 and the rotating head upper pressure plate 732 are both mounted on the connecting upright plate 733. The connecting upright plate 733 is installed on the end of the rotating head rod 72. Through the arrangement of the rotating head lower pressure plate 731 and the rotating head upper pressure plate 732, a clamping space for inserting the zipper tape can be effectively formed, thereby simply and effectively achieving the effect of clamping the zipper tape.

[0029] As an improved specific implementation, a plurality of connecting posts 734 are fixed on one side of the connecting plate 733. The ends of the connecting posts 734 facing away from the connecting plate 733 pass through the upper pressure plate 732 of the rotating head and are fixed on the lower pressure plate 731 of the rotating head. An elastic compression rod 735 is fixed on the side of the lower pressure plate 731 facing the upper pressure plate 732 of the rotating head. A compression cap 736 is coaxially fixed at the end of the elastic compression rod 735. A compression spring is provided between the compression cap 736 and the upper pressure plate 732 of the rotating head. By setting the connecting posts 734, the lower pressure plate 731 and the upper pressure plate 732 of the rotating head can be effectively fixed and installed on the connecting plate 733. At the same time, by setting the connecting posts 734 and the elastic compression rod 735, the elastic and retractable connection between the upper pressure plate 732 and the lower pressure plate 731 of the rotating head can be effectively realized, so that the clamping space formed between the two is a retractable and adjustable structure.

[0030] As an improved specific implementation, a cylinder connecting block 737 is fixed on the side of the rotating head pressure plate 732 facing away from the rotating head lower pressure plate 731. A positioning cylinder 738 is fixed on the cylinder connecting block 737. The cylinder body of the positioning cylinder 738 is fixedly installed on the cylinder connecting block 737. The push rod passes through the rotating head pressure plate 732 and extends into the clamping space to position the zipper tape in the clamping space. By setting the cylinder connecting block 737, a connection space for the positioning cylinder 738 can be effectively provided. By setting the positioning cylinder 738, the positioning of the zipper tape in the clamping space can be effectively realized, increasing the firmness of the zipper tape clamp 73 in clamping the zipper tape.

[0031] As an improved embodiment, the rotating head device 7 further includes a hook mechanism 74, which includes a lifting cylinder 741, a push hook cylinder 742, and a hook 743. The cylinder body of the lifting cylinder 741 is fixed to one end of the frame 1 near the rotating head rod 72. The cylinder body of the push hook cylinder 742 is fixedly mounted on the push rod of the lifting cylinder 741, so as to be driven by the lifting cylinder 741 to move up and down. The hook 743 is fixedly mounted on the push rod. On the push rod of the hook cylinder 742, one end of the rotating head pressure plate 732 and the rotating head lower pressure plate 731 is provided with a hook groove. The hook groove clamping space is connected so that the hook needle 743 can penetrate into the hook groove and hook the zipper tape in the clamping space. By setting up the lifting cylinder 741, the push hook cylinder 742 and the hook needle 743, the zipper tape can be gradually sent into the clamping space by the hook needle 743 hooking or releasing the zipper tape in cooperation with the positioning cylinder 738.

[0032] As an improved specific implementation, the cutting device 3 includes a cutting base 31, a conveyor belt mechanism 32, and a cutting mechanism 33. The cutting base 31 is installed below the feeding device 2, the conveyor belt mechanism 32 is installed on the upper side of the cutting base 31, and the cutting mechanism 33 is installed on the lower side of the cutting base 31. The conveyor belt mechanism 32 receives the zipper belt conveyed by the feeding device 2, and then guides the belt through the cutting base 31 before cutting it through the cutting mechanism 33. With the above-mentioned arrangement of the cutting base 31, conveyor belt mechanism 32, and cutting mechanism 33, the zipper belt output by the feeding device 2 can be effectively received and then cut by the cutting mechanism 33. In this embodiment, the zipper belt clamp 73 is located below the cutting mechanism 33. Therefore, the zipper belt first enters the clamping space between the upper pressure plate 732 and the lower pressure plate 731 of the rotating head through the action of the hook 743, and then the zipper belt is cut by the action of the cutting mechanism 33.

[0033] As an improved specific implementation, the tape cutting mechanism 33 includes a cutter assembly 331 and a positioning assembly 332. The cutter assembly 331 and the positioning assembly 332 are installed on the lower side of the cutting base 31. When cutting the tape, the positioning assembly 332 positions the zipper tape, and then the cutter assembly 331 cuts the zipper tape. By setting the positioning assembly 332 and the cutter assembly 331, the effect of positioning and cutting the zipper tape can be effectively achieved.

[0034] As an improved specific implementation, the cutter assembly 331 includes a cutter cylinder 3311, a cutter 3312, and a cutter plate 3313.

[0035] As an improved specific implementation, the positioning component 332 includes a knurled drive wheel 3321, a rubber-coated pressure wheel 3322, and a pressure cylinder 3323. The knurled drive wheel 3321 and the rubber-coated pressure wheel 3322 are rotatably mounted on the left and right sides of the through hole, respectively. The cylinder body of the pressure cylinder 3323 is fixedly mounted on the lower side of the cutting base 31. The rubber-coated pressure wheel 3322 is mounted on the push rod of the pressure cylinder 3323 and is driven by the pressure cylinder 3323 to cooperate with the knurled drive wheel 3321 to clamp or release the zipper tape passing through the through hole. With the above structure, the zipper tape can be clamped by the cooperation of the mutually rolling rubber-coated pressure wheel 332 and the knurled drive wheel 3321, which effectively positions the zipper tape and facilitates the cutting component 331 to cut the zipper tape.

[0036] As an improved specific implementation, the tail-closing device 5 includes a monofilament feeding mechanism 51, an ultrasonic tooth-melting mechanism 52, and a discharge mechanism 53. The monofilament feeding mechanism 51 is used to output nylon monofilaments to the ultrasonic tooth-melting mechanism 52. The ultrasonic tooth-melting mechanism 52 receives the end of the zipper tape after threading, and after molding the end of the zipper tape, it is sent out through the discharge mechanism 53. By setting up the monofilament feeding mechanism 51, the ultrasonic tooth-melting mechanism 52, and the discharge mechanism 53, the tail-closing and discharge of the zipper tape after threading can be effectively achieved.

[0037] As an improved specific implementation, the monofilament feeding mechanism 51 includes a monofilament spool 511, a wire feeding assembly 513, and a cutting assembly 512. The monofilament spool 511 is rotatably disposed on the side of the ultrasonic tooth melting mechanism 52. The wire feeding assembly 513 and the cutting assembly 512 are sequentially disposed below the monofilament spool 511. After the nylon wire is pulled out from the monofilament spool 511, it passes downward through the wire feeding assembly 513 and is fed into the cutting assembly 512. After being cut by the cutting assembly 512, it is fed into the ultrasonic tooth melting mechanism 52. Through the above-mentioned arrangement of the monofilament spool 511, the wire feeding assembly 513, and the cutting assembly 512, the nylon wire can be effectively fed out and cut before being fed into the ultrasonic tooth melting mechanism 52.

[0038] As an improved specific implementation, the yarn feeding assembly 513 includes upper and lower cylinders 5131, a clamping cylinder 5132, and a yarn feeding seat 5133. The yarn feeding seat 5133 is slidably disposed below the monofilament spool 511. The upper and lower cylinders 5131 are installed near the monofilament spool 511. The yarn feeding seat 5133 is mounted on the push rod of the upper and lower cylinders 5131 and is driven to move up and down by the upper and lower cylinders 5131. A yarn feeding plate 5134 is fixed to one side of the yarn feeding seat 5133. The yarn feeding plate 5134 has a channel for nylon yarn to pass through. The cylinder body of the clamping cylinder (5132) is fixed to the yarn feeding seat 5133. The side of the yarn feeding plate 5134 facing the clamping cylinder 5132 has a clamping hole communicating with the channel. The push rod of the clamping cylinder 5132 can extend into the clamping hole to position or release the nylon thread in the channel. With the above structure, the clamping cylinder 5132 and the upper and lower cylinders 5131 can work together to achieve a quantitative nylon thread feeding effect. Specifically, firstly, the upper and lower cylinders 5131 drive the thread feeding seat 5133 to rise. At this time, the nylon thread slides in the channel. The movement of the nylon thread and the thread feeding seat 5133 is independent of each other. Then, the push rod of the clamping cylinder 5132 extends into the clamping hole and clamps the nylon thread through the side wall of the channel. Then, the upper and lower cylinders 5131 drive the thread feeding seat 5133 to descend. At this time, the thread feeding seat 5133 will descend with the nylon thread. This cycle is repeated to achieve a quantitative nylon thread feeding effect.

[0039] As an improved specific implementation, the ultrasonic tooth-melting mechanism 52 includes an upper tooth-melting mold 521, a lower tooth-melting mold 522, and a pressure belt assembly 523.

The pressure belt assembly 523 is installed near the tooth-melting space to press down the zipper tape with the end already inserted. By setting up the upper tooth-melting mold 521 and the lower tooth-melting mold 522, the tooth-melting space can be used to close the tail of the zipper tape with tooth-melting. By setting up the pressure belt assembly 523, the zipper tape can be effectively pressed and positioned during the tooth-melting process, making the closing process of the zipper tape more stable and reliable.

The lower support plate 5234 is installed on one side of the lower mold 522 of the melting teeth and is opposite to the upper pressing plate 5233. There is a channel between the upper pressing plate 5233 and the lower support plate 5234 for the zipper tape to pass through. The upper pressing plate 5233 is driven by the upper pressing belt cylinder 5232 to lower and press down on the zipper tape or to rise and release the zipper tape. With the above structure, the effect of pressing down or releasing the zipper tape can be effectively achieved. The overall structure is simple and easy to implement.

[0041] As an improved specific implementation, the upper pressure belt base 5231 is provided with a lifting slide bar that can be raised and lowered.
