Description

Technical Field

[0001] The utility model belongs to the technical field related to the improvement of nylon zipper thread removing equipment, and specifically relates to a nylon zipper automatic thread removing machine which is not easy to break during the thread removing process, has high thread removing effect and lower cost. Background Art

[0002] First, let me briefly introduce the nylon zipper 1. Figure 1 , comprising a chain 2 and cloth tapes 3 arranged on both sides of the chain 2; the cloth tapes 3 and the chain 2 are sewn together by silk threads, commonly, there are three silk threads on one side, 1 upper thread and 2 lower threads; there are also two silk threads on one side, one upper thread and one lower thread; three silk threads on one side are stronger than two silk threads on one side; usually, the upper thread is on the chain 2, and the lower thread is on the cloth tape 3.

[0003] With the development of the times, people are more and more pursuing novelty in clothing, and zippers, as an important auxiliary material of clothing, are also changing with each passing day. Nylon zippers are also designed with different-colored teeth, different-colored threads and other patterns, and there are more and more styles of nylon zippers. In order to improve the efficiency of removing nylon zippers, an automatic nylon zipper removing machine is needed.

[0004] The patent with Chinese Patent No. CN117144584A discloses an automatic thread removing machine for nylon zippers. The upper thread removing buffer device is horizontally arranged on the upper surface of the machine frame; the lower thread buffer device is vertically arranged inside the machine frame; two sets of upper thread removing buffer devices are provided, with a first connecting rod in the middle. The side end of the first connecting rod is threadedly connected to the machine frame, and a thread passing slider is connected to the surface of the first connecting rod in an inserted manner. A thread removing start induction switch is provided at the side end of the upper thread removing buffer device. The thread removing start induction switch and the thread removing stop induction switch are symmetrically distributed. The side ends of the thread removing start induction switch and the thread removing stop induction switch are connected to the machine frame through fasteners. This is the upper thread removing buffer device for nylon zippers. Under normal thread removing conditions, the tape output motor runs normally. As the zipper moves forward, when the slider touches the start induction switch, the thread removing motor starts to run. Since the speed of the thread removing motor is much greater than that of the tape output motor, when the thread passing slider touches the stop induction switch, the thread removing motor stops running. The sewing thread is guided into the collecting wire tube through the wire guiding wheel, and the reciprocating work is completed to automatically remove the upper thread; it should be noted that two sets of upper thread removing buffer devices are provided. Therefore, the problem of uneven tightness and length of the two upper threads is solved, and full-automatic thread removing is achieved. At the same time, each thread is provided with a thread break stop induction switch, and the main machine stops running when a thread breaks; in the lower thread buffer device, four thread passing sliders are symmetrically distributed. The four thread passing sliders are connected to a second thread passing slider in a vertically sliding manner. The side end of the second thread passing slider is connected to the machine frame through a rotating shaft and a fixed block; a start induction switch and a stop induction switch are provided at the side end of the lower thread buffer device. The start induction switch and the stop induction switch are symmetrically distributed and are connected to the machine frame through fasteners; this lower thread buffer device interacts with the upper thread removing buffer device. Under normal thread removing conditions, when the upper thread removing buffer device completes the upper thread removing work and the second thread passing slider touches the start induction switch, the thread removing motor starts to run. Since the speed of the thread removing motor is much greater than that of the tape output motor, during the upper thread removing buffer process, the second thread passing slider moves upward. When the thread passing slider touches the stop induction switch, the thread removing motor stops running. The sewing thread is guided into the collecting wire tube through the wire guiding wheel, and the reciprocating work is completed to finish the full-automatic thread removing work; four sets of lower thread buffer devices are provided. Therefore, the problem of uneven tightness and length of the four lower threads is solved. At the same time, each thread is provided with a thread break stop induction switch, and the main machine stops running when a thread breaks.

[0005] Since the four thread passing sliders in the lower thread buffer device are connected to the second thread passing slider in a vertically sliding manner, during operation, the lower thread has to pull the thread passing slider, so the lower thread must be able to bear the weight of the thread passing slider, which easily causes the lower thread to break, thus interrupting the thread removing work; in addition, the thread removing efficiency is relatively low. If the thread removing speed is forcibly increased, the frequency of lower thread breakage will increase significantly; moreover, the structure is complex and the manufacturing cost is high.

[0006] To this end, we have developed an automatic nylon zipper thread removal machine that is not prone to thread breakage during the thread removal process, has a high thread removal effect, and lower costs. Summary of the Invention

When the thread passing slider corresponds to the thread removal stop induction switch, the thread removal stop induction switch controls the corresponding collecting device to stop winding the thread.

[0010] Preferably, a thread breakage judge is correspondingly arranged for each thread removal buffer device; the thread passing through the corresponding thread passing slider passes through the corresponding thread breakage judge and then is connected to the corresponding collecting device; when the thread breakage judge detects a thread breakage, the control box controls the circuit of the whole machine to stop running.

[0025] The roller guiding assembly 20, the tape output motor 50, and the empty running device 60 are borrowed from the Chinese prior application CN117144584A, and will not be elaborated here.

[0026] In this embodiment, the thread collecting device 401 is arranged on a bracket (not marked) on the upper surface of the frame 10, that is, the height of the thread collecting device 401 is higher than the upper surface of the frame 10; such a setting facilitates the collection of threads and is beneficial to the high-speed collection of threads.

[0027] The threads respectively pass through a thread removing buffer device 90 and then are connected to the corresponding thread collecting devices 401 to achieve collection; the bottom threads also respectively pass through a thread removing buffer device 90 and then are connected to the corresponding bottom thread collecting devices 402 to achieve collection; the thread removing buffer devices 90 are respectively arranged on the frame 10; the guide rods 902 on the thread removing buffer devices 90 are arranged at an acute angle; there may be a height difference between different thread removing buffer devices 90 according to the actual situation.

[0028] The thread removal buffer device 90 comprises a support block 901; the support block 901 comprises two vertical plates (not marked), and the vertical plates are connected by a bottom plate (not marked); a guide rod 902 is arranged between the two vertical plates (not marked) of the support block 901; a wire-passing slider 903 is sleeved on the guide rod 902; the wire-passing slider 903 is used for threading, and when the length of the wire passing through the wire-passing slider 903 changes, the wire-passing slider 903 will slide along the guide rod 902 to achieve automatic adjustment and facilitate the collection of the wire; a limit block 906 is arranged on the guide rod 902 to prevent the wire-passing slider 903 from passing, and the limit block 906 is connected to the thread removal start sensing switch 906. 05 corresponding to the setting, when the line-passing slider 903 contacts the limit block 906, the line-removing start sensing switch 905 controls the corresponding collecting device to start winding up; a line-removing stop sensing switch 904 is provided along the movement direction of the line-passing slider 903 away from the limit block 906, when the line-passing slider 903 corresponds to the line-removing stop sensing switch 904, the line-removing stop sensing switch 904 controls the corresponding collecting device to stop winding up, and due to the inclined setting of the guide rod 902, the line-passing slider 903 will slide down along the guide rod 902 until it contacts the limit block 906, and the line-removing start sensing switch 905 controls the corresponding collecting device to start winding up again; and the operation is repeated.

[0029] Each wire removal buffer device 90 is correspondingly provided with a wire breakage judgement 907; the wire passes through the corresponding wire passing slider 903, and then passes through the corresponding wire breakage judgement 907, and then is connected to the collection device; when the wire breakage judgement 907 finds that the wire is broken, the control electrical box 70 controls the circuit of the whole machine to stop running. After the wire breakage problem is solved, the control electrical box 70 is turned on to resume the circuit of the whole machine and resume wire collection.

[0030] In this embodiment, the disconnection determiner 907 is disposed on the support block 901 , but may also be disposed on a different side from the support block 901 , such as on the frame 10 .

[0031] In this embodiment, the bottom plate of the thread removal buffer device 90 corresponding to the bottom line collecting device 402 can be set into a V shape to facilitate the installation of its bottom plate, so as to reduce the contact surface with the frame 10 and facilitate welding.

[0032] In this embodiment, one end of the thread removing buffer device 90 corresponding to the upper thread collecting device 401 is fixed to the frame 10 by screws.

[0033] During operation, first manually remove the thread ends and thread the corresponding threads as required, then start the motor 50 with the belt, and the roller guiding assembly 20 will start to convey the nylon zipper 1. First, collect the upper thread, and then collect the lower thread. The chain 2 will fall inside the frame 10 due to its own weight, and the tape 3 will be pulled out by the tape-out motor. When the length of the thread passing through the thread-passing slider 903 changes, the thread-passing slider 903 will slide along the guide rod 902 to achieve automatic adjustment, facilitating the collection of the thread. When the thread-passing slider 903 contacts the limit block 906, the thread-removing start induction switch 905 controls the corresponding collection device to start winding the thread. A thread-removing stop induction switch 904 is arranged along the movement direction of the thread-passing slider 903 away from the limit block 906. When the thread-passing slider 903 corresponds to the thread-removing stop induction switch 904, the thread-removing stop induction switch 904 controls the corresponding collection device to stop winding the thread. Since the guide rod 902 is inclined, the thread-passing slider 903 will slide down along the guide rod 902 until it contacts the limit block 906, and the thread-removing start induction switch 905 controls the corresponding collection device to start winding the thread again; and so on for repeated operation.
