[0001] The utility model relates to the technical field of zipper production equipment, and specifically, it is a pull head feeding mechanism. Background Art

[0002] A zipper includes two zipper tapes, a pull head, and corresponding teeth on the zipper tapes.

[0003] During the feeding process of the pull head vibrating bowl, the pull heads will enter the feeding track in sequence to achieve feeding. However, there are a large number of pull heads in the vibrating bowl, and the pull heads that have not entered the feeding track will continue to rotate in the vibrating bowl, and it may take a long time to enter the feeding track, which easily causes wear and paint loss of these pull heads and fails to meet the appearance quality requirements of the pull heads.

[0004] To solve the above problems, in the prior art, the Chinese invention patent application with the publication number CN108720187A discloses a pull head feeding mechanism of a zipper machine, which includes a frame. A feeding component is further provided on the frame. The feeding component includes a first mounting bracket, a feeding cylinder, and a power source. The first mounting bracket is fixedly installed on the frame. The feeding cylinder is installed at the upper end of the first mounting bracket and is connected to a power source that drives it to rotate. One end of the feeding cylinder is open and is arranged obliquely with the opening facing upward. The open end of the feeding cylinder is located above the vibrating bowl, and a spiral track is formed on the inner wall of the feeding cylinder. Its power source motor is directly connected to the feeding cylinder. This connection method has a simple structure and high efficiency, but there are also the following problems. For example, any imbalance of the motor or uneven load will be directly transmitted to the other party, resulting in vibration problems of the entire equipment, affecting the equipment life and working efficiency. In addition, in order to ensure the alignment of the motor shaft and the load shaft, very precise installation is required. Otherwise, the misalignment problem will cause additional wear and failures.

The feeding cylinder and the power source are mounted on the mounting bracket, and the power source drives the feeding cylinder to rotate through a belt drive structure. The belt drive structure includes a driving wheel, two driven wheels, and a belt cooperatively connected between the driving wheel and the two driven wheels. Among them, the driving wheel is connected to the power source, and the two driven wheels are respectively mounted on two rotating shafts. An inductor for sensing the amount of materials in the vibrating disk is mounted on the mounting bracket.

[0009] As a further solution of the present utility model, one end of the feeding cylinder is open and is arranged in an inclined manner with the opening facing upwards, and a spiral track is formed on the inner wall of the feeding cylinder.

[0010] As a further solution of the present utility model, both of the rotating shafts are rotatably mounted on the mounting bracket, and a support roller is provided at each end of each rotating shaft. The feeding cylinder is supported on the four support rollers, and the outer circle of the feeding cylinder is tangent to the four support rollers.

[0015] As a further solution of the present utility model, a tensioning wheel is provided on the mounting bracket, and the tensioning wheel abuts against the outer side of the belt.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] Due to the above structural design, that is, the power source drives the feeding cylinder through the belt drive structure.

[0030] Embodiment:

[0031] Such as Figure 1and Figure 2 As shown in Figure 2 , a pull head feeding mechanism of the present application includes a mounting bracket 100, a feeding cylinder 200, and a power source 300. The feeding cylinder 200 and the power source 300 are mounted on the mounting bracket 100. The power source 300 drives the feeding cylinder 200 to rotate through a belt drive structure 400. Specifically, in implementation, the mounting bracket 100 at least includes an inclined mounting plate. The power source 300 is a stepper motor and is located on the side with a lower horizontal height of the mounting plate, while the belt drive structure 400 is located on the side with a higher horizontal height of the mounting plate. Through the above structural design, the stepper motor drives the feeding cylinder 200 to rotate through the belt drive structure 400. Since the belt drive has a certain elasticity, it can absorb the impact and vibration generated during startup and operation, reduce the influence on the motor and the feeding cylinder, and extend the service life; and the belt drive allows a certain degree of shaft alignment error, making the installation and debugging process relatively simple.

[0032] Specifically, the belt drive structure 400 includes a driving wheel 401, two driven wheels 402, and a belt 403 cooperatively connected between the driving wheel 401 and the two driven wheels 402. Among them, the motor shaft of the stepper motor passes through the mounting bracket 100 and is connected to the driving wheel 401, and the two driven wheels 402 are respectively mounted on two rotating shafts 101; the two rotating shafts 101 are rotatably mounted on the mounting bracket 100 through bearings, and a support roller 102 is provided at each end of each rotating shaft 101. The feeding cylinder 200 is supported on the four support rollers 102, and the outer circle of the feeding cylinder 200 is tangent to the four support rollers 102.

[0033] Specifically, one end of the feeding cylinder 200 is open and is arranged in an inclined manner with the opening facing upward, and a spiral track 201 is formed on the inner wall of the feeding cylinder 200.

[0035] Specifically, a guide hopper 202 is provided below the opening of the feeding cylinder 200.

[0036] Specifically, a baffle plate 203 mounted on the mounting bracket 100 is provided between the guide hopper 202 and the mounting bracket 100 to prevent the material from falling from the opening of the feeding cylinder 200 onto the belt drive structure 400, causing harm to the belt drive structure 400 and affecting the normal operation of the present application.

[0037] Specifically, an inductor 500 for sensing the amount of materials in the vibrating bowl is installed on the mounting bracket 100. The inductor 500 is installed on a mounting rod 501, and the mounting rod 501 is installed on the side plate of the mounting bracket 100. The side plate is located on one side of the mounting plate. When the inductor 500 senses that there is not enough material in the vibrating bowl located under the feeding hopper 202, the stepping motor drives the feeding cylinder 200 to rotate. Under the action of the spiral track 201, the materials are sent out and fall on the vibrating bowl.

[0038] As a preferred embodiment of this embodiment, a tension pulley 104 is provided on the mounting bracket 100. The tension pulley 104 is located below the opening of the feeding cylinder 200 and is rotatably installed on the mounting bracket 100.
