Description

Technical Field

[0001] This utility model relates to the field of woven bag processing technology, and specifically to a wire drawing device for woven bag processing with positioning function. Background Technology

[0002] The filament drawing device for woven bag processing is one of the core equipment in woven bag production. It is mainly used to process plastic raw materials (such as polypropylene and polyethylene granules) into flat or round filaments required for weaving. Its performance directly affects the key indicators such as the strength and toughness of woven bags.

[0003] Chinese utility model patent CN220946657U discloses a drawing mechanism for processing polypropylene woven bags, including a frame (1) and a take-up roller (2). The mechanism is characterized by: a drawing and heat dissipation mechanism on the outside of the frame (1); the drawing and heat dissipation mechanism includes a mounting bracket (3) fixedly installed on the right side of the frame (1), a drive motor (4) fixedly installed on the outside of the mounting bracket (3), a first connecting piece (5) fixedly connected to the output shaft of the drive motor (4), a second connecting piece (6) rotatably connected to the inside of the mounting bracket (3), and the left side of the take-up roller (2)... Connecting columns (7) are fixedly connected to the right sides. The outer surfaces of the first connecting piece (5), the second connecting piece (6) and the connecting column (7) are all provided with threaded holes (8) of the same size. The threaded holes (8) are connected to positioning bolts (9) by internal threads. The top of the frame (1) is fixedly connected to a heat sink (10). A heat sink fan (11) is fixedly installed on the top of the heat sink (10). However, the heat sink fan of the prior art only delivers air from the top, and the airflow is difficult to cover multiple layers of flat wire. In the prior art, the flat wire is in high-speed movement during operation and may deviate from the guide path due to vibration, resulting in uneven arrangement when winding. Utility Model Content

[0004] The purpose of this invention is to provide a wire drawing device for woven bag processing with positioning function, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a woven bag drawing device with positioning function, comprising a base plate, a ventilation hood fixedly connected to the top of the base plate, fans being matrix-mounted on the top of the base plate and the top of the inner wall of the ventilation hood, a plurality of placement slots being equidistantly opened on opposite sides of the inner wall of the ventilation hood, a lead screw being rotatably connected to the bottom of the inner wall of the placement slot, one end of the lead screw passing sequentially through a ball nut set on a slider and the top of the ventilation hood, and extending to the outside of the ventilation hood and fixedly connected to the output end of a first motor, the sliders being in pairs as a group, each group of sliders being connected on opposite sides by a limiting rod, and limiting posts being matrix-fixedly connected to the surface of the limiting rod.

[0006] Preferably, support plates are fixedly connected to both sides of the top of the base plate, and the opposite side of the support plates is connected by a rotating shaft. Limiting posts are fixedly connected to the surface of the rotating shaft in a matrix pattern. One end of the rotating shaft passes through the support plate and extends to its outside to be fixedly connected to the output end of the second motor.

[0007] Preferably, the ventilation hood has several ventilation slots at equal intervals on both sides, and the ventilation slots and placement slots are alternately distributed on the base plate.

[0008] Preferably, the fan mounted on the top of the base plate and the fan mounted on the top of the inner wall of the ventilation hood are symmetrically distributed about the center of the ventilation hood.

[0009] Preferably, the ventilation hood is distributed parallel to the support plate on the top of the base plate.

[0010] Preferably, the lead screw is threadedly connected to the ball nut.

[0011] The beneficial effects of this utility model are as follows: heat dissipation treatment is carried out on both the upper and lower sides of the flat wire at the same time to avoid material performance deviation caused by local overheating. During the high-speed operation of the flat wire, it is ensured that it runs stably along the guide path, the winding and arrangement accuracy is greatly improved, and the scrap rate caused by uneven arrangement is reduced.

[0012] To achieve simultaneous heat dissipation on both the top and bottom sides of the flat wire:

[0013] Further configuration: fans are installed in a matrix on the top of the base plate and the top of the inner wall of the ventilation hood, and several ventilation slots are equally spaced on both sides of the ventilation hood.

[0014] By adopting the above technical solution, the fans installed on the top of the base plate and the top of the inner wall of the ventilation hood are activated, and heat dissipation is carried out on the upper and lower sides of the flat wire.

[0015] To ensure stable operation along the guide path during high-speed operation:

[0016] Further configuration: The surface matrix of the limiting rod is fixedly connected to the limiting post.

[0017] By adopting the above technical solution, the flat wire can always be located in the middle of the two limiting posts, reducing the scrap rate caused by misalignment.

[0018] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Fans 10 are installed in a matrix on the top of the base plate 1 and the top of the inner wall of the ventilation hood 2. Several placement slots 3 are equally spaced on opposite sides of the inner wall of the ventilation hood 2. A lead screw 4 is rotatably connected to the bottom of the inner wall of the placement slot 3.

[0026] Support plates 101 are fixedly connected to the top of the base plate 1 on both sides. The opposite side of the support plates 101 is connected by a rotating shaft 102. Limiting posts 9 are fixedly connected to the surface of the rotating shaft 102 in a matrix manner. One end of the rotating shaft 102 passes through the support plate 101 and extends to its outside to be fixedly connected to the output end of the second motor 103.

[0027] Several ventilation slots 11 are provided at equal intervals on both sides of the ventilation hood 2, and the ventilation slots 11 and the placement slots 3 are alternately distributed on the base plate 1.

[0033] The working process of this woven bag processing wire drawing device with positioning function is as follows:

[0034] First, the second motor 103 is started, which drives the rotating shaft 102 to rotate, thereby drawing the heated and softened woven bag processing material into flat filaments, which are then wound onto the surface of the rotating shaft 102. During the drawing process, the fan 10 is started to dissipate heat from the flat filaments. The flat filaments are restricted between the two limiting posts 9 to prevent sticking. When drawing, the first motor 7 drives the lead screw 4 to rotate. The lead screw 4 and the ball nut 6 cooperate with each other to drive the limiting rod 8 up and down through the slider 5, thereby adjusting the surface tension of the flat filaments and preventing breakage.
