Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of woven bag processing equipment, and specifically discloses a wire drawing device for processing plastic woven bags. Background Technology
[0002] Woven bags are packaging bags made primarily of plastic raw materials such as polypropylene (PP) or polyethylene (PE), which are extruded and stretched into flat filaments and then woven together. Because their texture resembles snakeskin, they are commonly known as "snakeskin bags." They are characterized by high strength, weather resistance, and low cost. The main production process involves using plastic raw materials to extrude film, cut, and unidirectionally stretch them into flat filaments, which are then woven together to obtain the product.
[0003] Chinese patent CN221797764U discloses a wire-drawing device for processing plastic woven bags, including a base plate and a box. The upper surface of the base plate is fixedly connected to the lower surface of the box. The output shaft of the first motor passes through a second vertical plate and is fixedly connected to a second roller via a reducer. The upper surface of the base plate is provided with a wire-drawing adjustment structure. The inner wall of the box is provided with a cooling structure for processing plastic woven bags. Through the cooperation of the cooling structure and water pipes, a third motor is started, driving the first bevel gear to rotate. The rotation of the first bevel gear drives the rotation of the second bevel gear, and simultaneously drives the cylinder to rotate inside the second outer shell. The device moves and drives the third bevel gear to rotate, which in turn drives the threaded rod to rotate inside the second housing. This causes the water pipe to move and cool the plastic woven bag filaments, preventing them from shaking, damaging them, and wasting resources. However, the device lacks a filament drying function, causing water droplets to fall onto the bottom plate or ground during the winding process using the second roller. This makes it difficult to maintain a clean working environment. Therefore, to solve this problem, this invention proposes a filament drawing device for processing plastic woven bags. Utility Model Content
[0004] The present invention aims to provide a wire drawing device for processing plastic woven bags, which has a wire drawing and drying function, and can prevent residual water droplets on the wire from falling to the ground, thus ensuring a clean working environment for wire drawing.
[0005] This utility model is achieved through the following technical solution:
[0006] A drawing device for processing plastic woven bags includes a base and a cooling and drying mechanism. The cooling and drying mechanism is located above the base, and a tensioning and winding mechanism is located on one side of the cooling and drying mechanism. The cooling and drying mechanism includes a housing, and a partition is connected inside the housing. The two sides of the partition are a cooling chamber and a drying chamber, respectively. A top plate and a support are respectively located above the cooling chamber and the drying chamber. Two connecting pipes are symmetrically connected to the top inner side of the support, and a hot air fan is connected above the connecting pipes. The tensioning and winding mechanism includes a U-shaped frame, and a first telescopic rod is connected to the lower middle part of the U-shaped frame. A vertical plate is located on the side of the first telescopic rod away from the housing, and a winding shaft is rotatably connected to the upper end of the vertical plate. A second telescopic rod is connected to the lower part of the side of the vertical plate away from the winding shaft.
[0007] As a further feature of the above solution, limiting grooves are provided at both ends of the upper part of the box and at the upper end of the partition to facilitate the wire drawing through the box for sequential cooling and drying. Drain pipes are connected to the lower end of one side of the cooling chamber and the drying chamber to facilitate the drainage of water from the cooling chamber and the drying chamber. A water inlet pipe is connected to the upper end of one side of the cooling chamber to facilitate the injection of cold water into the cooling chamber. Guide rollers are rotatably connected to both sides of the inner wall of the cooling chamber to ensure that the wire drawing is immersed in the cold water in the cooling chamber.
[0008] As a further feature of the above solution, both sides of the top plate and the support are detachably connected to both sides of the housing, facilitating the disassembly and assembly of the top plate, the support and their connecting components, providing space for the wire to pass through the cooling chamber and the drying chamber. Both ends of the connecting pipe are connected to the support, and the side of the connecting pipe away from the hot air blower is connected to multiple air outlet pipes arranged in a linear array, which helps to evenly blow hot air onto the wire. The hot air blower is connected to the support, facilitating the installation and maintenance of the hot air blower.
[0009] As a further feature of the above solution, two limiting rollers are rotatably connected to the inner ends of the U-shaped frame, which can limit the position of the wire drawing and facilitate the extension and retraction of the first telescopic rod to drive the U-shaped frame, the limiting rollers, and the wire drawing to move up and down, thereby tensioning the wire drawing. A limiting hole is provided at one end of the base near the upright plate, and a sliding rod is connected to the lower part of the upright plate. The sliding rod passes through the interior of the limiting hole and is slidably connected to the limiting hole, which can limit the movement direction of the upright plate and its connecting parts. A limiting ring is detachably connected to the outer side of the sliding rod to prevent the sliding rod from being pulled out of the limiting hole.
[0010] As a further feature of the above solution, one end of the take-up shaft is connected to a motor, which can drive the take-up shaft to rotate. The outer side of the second telescopic rod is connected to the base, which facilitates the installation and maintenance of the second telescopic rod.

[0012] The winding shaft involved in this utility model includes, but is not limited to, an air shaft.
[0013] The present invention has the following beneficial effects during use:
[0014] The use of guide rollers in the cooling chamber of the cooling and drying mechanism can limit the position of the wire drawing in the cooling chamber and ensure that the wire drawing is immersed in the cold water in the cooling chamber. The top plate and bracket are detachably connected to the box body, which makes it convenient for users to pass the wire drawing through the cooling chamber and the drying chamber in sequence. The use of two hot air blowers and connecting pipes can inject high-temperature airflow into the drying chamber to dry the wire drawing.
[0015] The combination of the first telescopic rod and the two limiting rollers can adjust the distance between the limiting rollers and the base by extending and retracting the first telescopic rod, thereby adjusting the distance between the high or low point of the wire drawing located between the two limiting rollers and the base, and tightening the wire drawing. The combination of the second telescopic rod and the slide rod can drive the upright plate and the winding shaft to move back and forth during the winding process, so that the wire drawing is evenly wound on the sleeve sleeved on the outside of the winding shaft, ensuring the quality of winding.

The lower ends of one side of the cooling chamber 212 and the drying chamber 213 are connected to drain pipes 215 to facilitate the drainage of water from the cooling chamber 212 and the drying chamber 213. The upper end of one side of the cooling chamber 212 is connected to a water inlet pipe 216 to facilitate the injection of cold water into the cooling chamber 212. The inner walls of the cooling chamber 212 are rotatably connected to guide rollers 22 to ensure that the wire drawing is immersed in the cold water in the cooling chamber 212.
[0028] like Figure 1 , Figure 2 and Figure 5 As shown, the top plate 23 and the bracket 24 are detachably connected to the two sides of the housing 21, respectively, which facilitates the disassembly and assembly of the top plate 23, the bracket 24 and their connecting parts, and provides space for the wire to pass through the cooling chamber 212 and the drying chamber 213. Both ends of the connecting pipe 25 are connected to the bracket 24. The side of the connecting pipe 25 away from the hot air blower 26 is connected to a plurality of air outlet pipes 251 arranged in a linear array, which helps the hot air to be blown evenly onto the wire. The hot air blower 26 is connected to the bracket 24, which facilitates the installation and maintenance of the hot air blower 26.
[0029] like Figure 1 , Figure 2 and Figure 6 As shown, two limiting rollers 32 are rotatably connected to the inner ends of the U-shaped frame 31, which can limit the position of the wire drawing and facilitate the extension and retraction of the first telescopic rod 33 to drive the U-shaped frame 31, the limiting rollers 32 and the wire drawing to move up and down, thereby tightening the wire drawing. The base 1 is provided with a limiting hole 11 at one end near the upright plate 34. A sliding rod 341 is connected to the lower part of the upright plate 34.
