Description

Technical Field

[0001] The invention relates to the technical field of automatic zipper threading equipment, and in particular to a zipper threading machine capable of automatically threading a slider on a zipper. Background Art

[0002] The pull head refers to the zipper head used on the zipper, and the automatic zipper threading machine refers to the equipment that installs the pull head on one section of the zipper to produce the finished zipper. In the process of processing the finished zipper by the automatic zipper threading machine, the material is first loaded through the rolled zipper, that is, the zipper is a long section that has not been cut; the zipper here refers to the semi-finished product that has not yet been installed with the pull head; at the same time, the pull head is loaded, such as loading through a vibration plate (feeding plate), and finally after the pull head is installed on the zipper, according to the needs of products such as clothes, bags, etc., the section where the pull head is installed is cut off to obtain the finished zipper, which can be used on products such as clothes, bags, etc.; the zipper described here includes cloth tapes on both sides and meshing teeth on both sides in the middle; and the pull head may be worn with one or two (double pull heads). Such equipment generally includes zipper dotting devices, zipper installation devices, etc. In order to adapt to the subsequent products that will be installed with zippers, for example, zippers are used on bags, and the bags will be marked at different positions at the opening where the zippers are installed. Because the length of the zipper installation position is long, there are several marking positions, so several more positions on the zipper are also required to be marked. As for the dot printing device, an electric heating structure is generally used for marking, which has the following problems: 1. The mark is obtained by heating, so the mark itself is large and the dot printing position is not clear; 2. Because the mark itself is large, the position is not accurate, which does not correspond to the comparison of subsequent products using zippers. As for the zipper installation device, the slider installation device needs to meet the following requirements: Because a small number of sliders in a batch of sliders have errors, the designed mold is required to be 100% consistent with the shape of the same batch of sliders and the mold. If the mold is not matched well, the slider moves during the installation process, resulting in defects after the slider is installed on the zipper, and a high rate of misalignment. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention aims to provide an automatic zipper threading machine.

[0004] The technical solution is: an automatic zipper threading machine, including a frame, a mounting plate arranged in the frame, and also including a loading tray, a pull head outlet device, a pull head delivery device, a pull head installation device, which are installed on the upper surface of the installation plate in sequence according to the sequence of working processes, and a clamping device, a dot printing device and a chain cutting and splitting device which are located in the process after the pull head installation device and are installed on the upper surface of the installation plate; the pull head from the loading tray is transmitted to the pull head outlet device, and then reaches the pull head delivery device and the pull head installation device in sequence, and then the pull head is transmitted to the chain cutting and splitting device by the pull head installation device. At this time, the clamping device drives the front end of the zipper wound on the material tray to pass through the dot printing device and the chain cutting and splitting device in sequence. When passing through the chain cutting and splitting device, the pull head is installed on the zipper and the chain cutting and splitting device cuts off the front end of the zipper and the section where the pull head is put on according to the set length.

[0005] Technical effect: The zipper threading machine of the present invention needs to load the zipper and the slider separately. The slider from the loading tray is transmitted to the slider outlet device, and then is accurately transmitted to the mold of the slider feeding device (that is, the clamping head assembly for fixing the slider) by the slider feeding device, and then the slider is accurately transmitted to the mold of the slider installation device by the slider feeding device, and then the slider is transmitted to the chain cutting and chain splitting device by the slider installation device; at this time, the clamping device drives the zipper wound on the material tray to be loaded, and the front end of the zipper passes through the dot printing device and the chain cutting and chain splitting device in turn. When passing through the chain cutting and chain splitting device, the slider is installed on the zipper and the chain cutting and chain splitting device cuts off the front end of the zipper and the section where the slider is put on according to the set length. The dot printing device used in the zipper threading machine has the following advantages: ultrasonic dot printing is used for marking. After the two dot printing pressure heads contact the ultrasonic dot printing welding head, the edges of the cloth tapes on both sides of the zipper passing between the two are marked with a mark, and the mark is a narrow line, which can accurately correspond to the mark on the product used on the zipper; therefore, the mark made by the dot printing device of the present invention is accurately positioned, which is convenient for the subsequent use of the zipper; the slider installation device meets the design requirements and has the following advantages: 1. The mold uses the average value of the copied numbers of multiple sliders of the same number (same specification) to make the slider mold, so that the slider mold can adapt to the sliders with errors in the same specification of sliders, and can reduce the mismatch between the slider and the mold; 2. The use of the above-mentioned slider mold is more accurate, the slider and the mold have a good fit, and the slider movement is avoided, which is conducive to reducing the misalignment rate of the finished product.

DETAILED DESCRIPTION

[0064] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0065] like Figure 1-Figure 5bAs shown, an embodiment of the present invention provides an automatic zipper threading machine, comprising a frame 1, a mounting plate 101 arranged in the frame, and further comprising a loading plate 2, a pull-out device 3, a pull-out feeding device 4, a pull-out installation device, and a clamping device 5, a dotting device 6, and a chain cutting and splitting device 7 which are located in a process after the pull-out installation device and are installed on the upper surface of the mounting plate 101; the zipper threading machine operates according to the following process: the pull-out device from the loading plate 2 is transmitted to the pull-out device 3, and the pull-out feeding device 4 is installed on the upper surface of the mounting plate 101 in sequence according to the process sequence. The slider device 3, and then reaches the slider feeding device 4 and the slider installing device in turn, and then the slider installing device transmits the slider 10 to the chain cutting and chain splitting device 7. At this time, the front end of the zipper 11 of the feeding material passes through the dot printing device 6 to reach the chain cutting and chain splitting device 7, and then the front end of the zipper 11 is driven by the clamping device 5 to pass through the chain cutting and chain splitting device 7. In the process of passing through the chain cutting and chain splitting device 7, the slider 10 is installed on the zipper 11 and the chain cutting and chain splitting device cuts off the front end of the zipper and the section where the slider is put on according to the set length. Here, the clamping device 5, the dot-marking device 6 and the chain cutting and splitting device 7 operate simultaneously, that is, the clamping device 5 clamps the front end of the zipper 11 and then pulls the zipper forward. The dot-marking device 6 is based on design requirements. For example, the cut zipper is used on clothes, and there are several marks (marks) at the position where the zipper is installed on the clothes. In order to correspond the marks on the clothes when the finished zipper is installed on the clothes, several marks are also marked on the zipper. The slider installation device transmits the slider to the mold of the chain cutting and splitting device 7, and the slider 10 is installed on the zipper 11 at this position. The clamping device 5 continues to drag the zipper 11 forward. When the length of the front section of the zipper reaches the length of a single finished zipper, the chain cutting and splitting device 7 cuts off the front section of the long zipper to obtain a single finished zipper with a slider. Here, the zipper is usually loaded by winding a long section of the zipper on a material tray, and then the front end of the long section of the zipper is introduced into the dot printing device 6, and then the front end of the zipper is transmitted to the chain cutting and separating device 7 through the dot printing device.

[0066] This embodiment is explained by taking the installation of two sliders on the zipper as an example, so the loading tray 2 and the slider outlet device 3 are both two sets and the two sets are the same, that is, the two sets of loading trays 2 are exactly the same, and the two sets of slider outlet devices 3 are also the same; the slider installation device includes a first slider installation device 8 and a second slider installation device 9; the two sets of identical loading trays 2 respectively supply sliders 10 to the two sets of identical slider outlet devices 3, and in order to stably transmit the sliders, a material channel 201 for batch sliders to pass through is provided between the loading tray 2 and the slider outlet device 3; one set of the slider outlet device 3 transmits the slider to the slider device 4, and then the slider device 4 is supplied to the first slider outlet device 8, and the slider outlet device 8 is supplied to the second slider outlet device 9; A pull-head installation device 8 transmits the pull-head, and then the first pull-head installation device 8 transmits the received pull-head to the chain cutting and chain splitting device 7; another set of pull-out pull-head device 3 transmits the pull-head 10 to the second pull-head installation device 9, and the second pull-head installation device 9 transmits the pull-head to the chain cutting and chain splitting device 7; that is, the second pull-head installation device 9 here is directly connected with the pull-out pull-head device 3, and sends the pull-head to the chain cutting and chain splitting device 7 after receiving it, so the second pull-head installation device 9 has the functions of sending and installing the pull-head; a linear guide rail 102 is provided on the frame 1, and a transverse slider is provided on the linear guide rail, and the clamping device 5 is connected to the transverse slider. The linear guide rail 102 of this embodiment is a commercially available standard part, and a motor is provided on the linear guide rail, which can drive the transverse slider to move back and forth after the motor is started.

During the retreat process, the gap between the two rollers 503d respectively provided on the two clamping finger fixing seats 503b first reaches the two first protrusions 708a of the cutting guide block 708, that is, the two rollers 503d are respectively aligned with the first protrusions 708a. 8a are in contact, the two rollers are squeezed by the cutting guide block 708 and move to both sides, thereby driving the two clamping finger fixing seats 503b and the two clamping fingers 503c to move to both sides (i.e., stretching the two clamping fingers), and the two rollers 503d continue to move and pass through the front plane 708b and the second protrusion 708c in sequence. In this process, the two clamping fingers 503c clamp the cloth tapes on both sides of the pulling teeth and move to both sides, thereby driving the front ends of the meshing teeth to be separated (i.e., the tooth separation process); the two clamping fingers 503c drive the zipper to continue to move with the clamping bracket 501. In this process, the slider 10 clamped in the double-pull front upper mold 704e and the double-pull rear upper mold 704f is installed on the zipper; then the two clamping fingers 503c The zipper 11 is clamped and continues to move while the slider 10 installed on the zipper and located in the double-pull front upper mold 704e and the double-pull rear upper mold 704f remains stationary, that is, the zipper moves relative to the two sliders. Therefore, in this process, the slider 10 located in the double-pull rear upper mold 704f closes the separated teeth on both sides (equivalent to closing the teeth of the zipper by pulling the zipper), and at this time, the slider 10 located in the double-pull front upper mold 704e continues to separate the closed teeth (equivalent to opening the teeth of the zipper by pulling the zipper). When the two sliders 10 reach the appropriate positions of the zipper 11, the two sliders are separated from the double-pull front upper mold 704e and the double-pull rear upper mold 704f respectively. At this time, only the teeth between the two sliders 10 are separated, and the teeth at other positions are in a meshing state.After the two rollers 503d leave the second protrusion 708c, the two material clamping finger fixing seats 503b are pushed back to their original positions under the action of the material clamping reset spring 504; when the zipper moves forward to a set length, the cutting cylinder 702b is started, driving the cutting cylinder connector 702c, the upper knife fixing seat 703a and the lower cutting knife 703b to move downward, and the longitudinal tooth punching plate 7032b is combined with the tooth punching notch 7032c to punch the teeth of the zipper; the upper edge A of the square lower notch 7031b is combined with the edge B between the two lower sliders 7034c on the lower fixed cutting knife 703c to cut the zipper tape, and a finished zipper with a slider installed is obtained. ;
