Technical Field

[0001] The utility model relates to the technical field of zipper production, in particular to a zipper belt knitting machine with a wire break alarm mechanism. Background Art

[0002] Zipper tape is a kind of daily necessity that people often use in their lives. Zipper tape can be seen on clothing and bags. Conventional zipper tape is usually composed of chain teeth, cloth tape, slider, etc. When weaving zipper tape, a zipper tape weaving machine is needed. It is an automated machine that can efficiently weave the fabric part of the zipper tape, including the opening and fixed part of the zipper. This machine can improve production efficiency and ensure product quality consistency when manufacturing zipper tapes. The working principle of the zipper tape weaving machine is usually to control the machine to weave through a pre-set program, and produce the shape and size of the zipper tape fabric according to the design requirements.

[0003] When the existing zipper tape weaving machine is in use, the silk thread used to weave the zipper tape is released from the wire roller. Since the silk thread wound on the wire roller will be used up and the wire will break during the zipper tape weaving process, if the silk thread is not processed in time, the weaving work of the zipper tape will be interrupted, and the conveyed chain teeth cannot be fixed on the zipper tape and will fall on the machine. For this reason, we propose a zipper tape weaving machine with a wire breakage alarm mechanism. Utility Model Content

[0004] The purpose of the utility model is to provide a zipper tape weaving machine with a wire breakage alarm mechanism to solve the problem raised in the above-mentioned background technology that wire breakage may occur during the zipper tape weaving process. If the silk thread is not processed in time, the weaving work of the zipper tape will be interrupted, and the conveyed chain teeth cannot be fixed on the zipper tape and will fall on the machine.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a zipper tape knitting machine with a wire break alarm mechanism, comprising:

[0006] A braiding machine body, wherein a symmetrically arranged crossbar is fixed to the outer wall of the wire inlet side of the braiding machine body, and vertical bars are fixed to the edge sides of the surface of the crossbar, and parallel wire roller support plates and an upper limit plate located above the wire roller support plates are installed between the side walls of the vertical bars;

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model sets a detection component. When the main body of the knitting machine is working, the silk thread being pulled and transported is in a straight state. At this time, the limit bar can be pushed to the side away from the limit frame under the action of the silk thread tension. When the wire breaks or the silk thread is used up, the limit bar without silk thread restriction is reset and rotated under the action of the torsion spring, so that the limit bar applies pressure to the spring by pushing the arc bar. As the compression degree of the spring increases, the limit sliding piece will squeeze the push switch, causing the push switch to be disconnected, thereby disconnecting the power supply of the knitting machine main body, preventing the knitting machine main body from being in a working state when the wire is missing or broken, and prompting the workers to deal with the cause of the shutdown as soon as possible.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] See also Figure 1-Figure 3 A zipper tape knitting machine with a wire break alarm mechanism shown in the figure includes a knitting machine body 1, a symmetrically arranged cross bar 3 is fixed to the outer wall of the wire inlet side of the knitting machine body 1, and vertical bars 4 are fixed to the edge sides of the surface of the cross bar 3, and parallel wire roller support plates 5 and an upper limit plate 8 located above the wire roller support plate 5 are installed between the side walls of the vertical bars 4, a plurality of notches for replacing and placing wire rollers are fixed on the side wall of the upper limit plate 8, and detection components 9 equal to the number of notches are installed between the side wall of the upper limit plate 8 and the side wall of the wire roller support plate 5, and a push switch 10 connected to the power supply of the knitting machine body 1 is arranged inside the detection component 9, and an audible and visual alarm 2 is installed on the surface of the knitting machine body 1.

[0024] The number of detection components 9 is equal to that of notches, so as to detect each strand of silk thread pulled by the knitting machine body 1. The push-type switch 10 is a common switch type, which controls the power supply of the knitting machine body 1 to be disconnected when pressed. Several push-type switches 10 and the circuit of the knitting machine body 1 are in series structure.

[0025] Furthermore, the detection component 9 includes an extension bar 91 symmetrically arranged and fixed to the side wall of the line roller support sheet 5 and the side wall of the upper limit plate 8, wherein the side wall of the extension bar 91 on one side is fixed with an inner bar 92, and the end of the inner bar 92 is rotatably penetrated with a rotating column 93, and the bottom of the upper inner bar 92 is configured with a columnar groove, and a torsion spring 94 is arranged in the columnar groove and is located outside the rotating column 93, and the ends of the rotating column 93 are fixed with a turning connection bar 95, and the ends of the turning connection bar 95 are fixed with a limiting bar 96, and the upper extension bar 91 on the other side is fixed with a turning connection bar 95. A vertical block 97 is fixed to the bottom surface of the side wall of the long strip 91, and a limit frame 98 is installed on the outer wall of the vertical block 97. A spring 99 is arranged in the limit frame 98, and the end of the spring 99 abuts against the limit sliding piece 100. A through rod 101 passing through the limit frame 98 is fixed to the side wall of the limit sliding piece 100, and an arc strip 102 is fixed to the end of the through rod. The push switch 10 is arranged inside the limit frame 98, and the push switch 10 is located on the inner side of the spring 99. The internal structure of the limit frame 98 is provided with a rectangular slide groove adapted to the limit sliding piece 100.

[0026] The silk thread is in a straight state under normal traction. Under the action of the silk thread, the limit strip 96 can be controlled to deviate to one side so that the limit strip 96 does not contact the arc strip 102. At this time, the push switch 10 is in the on state, and the knitting machine body 1 works normally. When the silk thread on the wire roller is used up or the wire breaks during the knitting process, the limit strip 96 at the corresponding position loses the effect of the silk thread and is reset under the action of the torsion spring 94, causing the limit strip 96 to push the limit sliding piece 100 to move inside the limit frame 98 through the arc strip 102 and the penetration rod 101, and push the push switch 10 after squeezing the spring 99, causing the power of the knitting machine body 1 to be disconnected.

[0027] Furthermore, a driving motor 6 is installed on the bottom of the wire roller support plate 5, and a limited rotating seat 7 is rotatably arranged on the surface of the wire roller support plate 5. The bottom of the limited rotating seat 7 is transmission-connected to the output shaft of the driving motor 6, and the surface of the limited rotating seat 7 is constructed with a limiting groove for plugging in the bottom rotating shaft of the wire roller.

[0028] The output shaft of the driving motor 6 can drive the position-limiting rotating seat 7 to rotate, so that the wire roller inserted between the surface of the position-limiting rotating seat 7 and the notch rotates.

[0029] The present invention is a zipper tape knitting machine with a wire break alarm mechanism. The driving motor 6 drives the wire roller on the limit rotating seat 7 to rotate at a uniform speed. Under the action of the knitting needle and the wire roller, the silk thread is in a straight state and is continuously transported. At this time, under the action of the silk thread, the limit strip 96 is blocked by the silk thread and deviates to one side. The limit strip 96 does not contact the arc strip 102. At this time, the push-type switch 10 is in the on state, and the knitting machine body 1 works normally. When the silk thread on the wire roller is used up or the wire breakage occurs during the knitting process, the limit strip 96 at the corresponding position loses the wire function and is reset under the action of the torsion spring 94, causing the limit strip 96 to push the limit sliding piece 100 to move inside the limit frame 98 through the arc strip 102 and the penetration rod 101, and push the push-type switch 10 after squeezing the spring 99, causing the power of the knitting machine body 1 to be disconnected, and then the wire roller at the position where the wire breakage or insufficient silk thread occurs is promptly processed.
