[0020] like Figures 1-6 As shown, an embodiment of this utility model provides a plastic wire drawing machine equipped with a cooling component, comprising: The plastic drawing machine body 10 has a body 101, and a plurality of drawing rollers 103 for plastic drawing are provided on one side of the body 101. Furthermore, the plastic drawing machine body 10 has a base 102, which is fixedly installed on the bottom of the machine body 101; The plastic drawing machine body 10 also has a geared motor 104, which is fixedly installed on the base 102. The output shaft of the geared motor 104 is installed on the machine body 101 and is located inside the machine body 101. The output shaft of the geared motor 104 can drive the rotation of multiple drawing roller shafts 103. Multiple wire drawing rollers 103 and a geared motor 104 are connected by belt drive (not shown in the figure); A cooling assembly is mounted on the body 10 of the plastic drawing machine; The cooling components include: The reciprocating motion mechanism 20 is disposed above the plurality of wire drawing rollers 103 and can completely cover the plurality of wire drawing rollers 103; The jet structure 30 has a gas generating part and a jet part. The gas generating part is mounted on the body 101, and the jet part is mounted on the reciprocating motion mechanism 20. The gas generating part and the jet part are flexibly connected. The jetting portion of the jetting structure 30 is positioned toward the plurality of drawing rollers 103; The jetting part of the jetting structure 30 can reciprocate synchronously with the reciprocating motion mechanism 20, and during the reciprocating motion, it continuously jets and cools the plastic filaments on multiple drawing rollers 103, thereby shortening the cooling time of the plastic filaments.

[0021] In this embodiment, the base 102 on the plastic drawing machine body 10 supports the machine body 101. The reduction motor 104 and multiple drawing roller shafts 103 on the plastic drawing machine body 10 are driven by belts (not shown in the figure) to make the multiple drawing roller shafts 103 rotate synchronously to draw plastic into filaments. During plastic drawing, the cooling component is used to cool the plastic filaments. Specifically: The cooling assembly includes a reciprocating motion mechanism 20 and an air jet structure 30. Since the reciprocating motion mechanism 20 fully covers multiple drawing rollers 103, and the plastic filament is wound on multiple drawing rollers 103, after the reciprocating motion mechanism 20 and the air jet structure 30 cooperate with each other, the air jet part on the air jet structure 30 can cool the plastic filament wound on the multiple drawing rollers 103 by reciprocating motion, so as to shorten the cooling time of the plastic filament and improve the cooling effect of the plastic filament.

[0022] In this embodiment, to improve the performance of the plastic filaments and give them antistatic and anti-aging properties, conductive fillers (such as carbon black and metal fibers) and anti-aging components (such as UV absorbers and antioxidants) can be added to the plastic raw materials during the filament drawing process to achieve antistatic and anti-aging functions. Specifically: Antistatic properties Conductive fillers (such as carbon black and metal fibers): uniformly dispersed in plastic raw materials to reduce surface resistivity to 10. 8 -10 9 Ω effectively prevents static electricity buildup and shields against electromagnetic interference. Anti-aging properties Anti-aging components (such as UV absorbers and antioxidants) can inhibit photo-oxidative aging, improve the weather resistance of plastic raw materials, and extend the service life of products. Plastic raw material processing equipment with antistatic and anti-aging properties: A twin-screw extruder (not shown in the diagram) is used for preparing plastic raw materials. Mixing is achieved using a twin-screw extruder to ensure good compatibility between the conductive filler, anti-aging components, and plastic raw materials. Example

[0023] like Figures 1-6 As shown, improvements are made based on Example 1: Furthermore, the reciprocating motion mechanism 20 includes a main body, a driving part, and a sliding part. The driving part is mounted on the main body, the sliding part is mounted on the driving part, and the sliding part can reciprocate linearly on the main body. The jet component of the jet structure 30 is mounted on the sliding component of the reciprocating motion mechanism 20.

[0024] In this embodiment, the main body of the reciprocating motion mechanism 20 is used to support the sliding part and the driving part. When the driving part of the reciprocating motion mechanism 20 is working, the sliding part can move linearly on the main body. Since the jetting part of the jetting structure 30 is installed on the sliding part of the reciprocating motion mechanism 20, when the sliding part of the reciprocating motion mechanism 20 moves linearly, the jetting part of the jetting structure 30 can move synchronously with the sliding part of the reciprocating motion mechanism 20. When the jetting part of the jetting structure 30 moves, the ejected airflow can blow onto the plastic filaments on the multiple drawing rollers 103 and cool them.

[0025] Furthermore, the main body of the reciprocating motion mechanism 20 includes an inverted U-shaped base 201 and two fixed side plates 202, which are respectively fixedly installed at the openings at both ends of the inverted U-shaped base 201. The sliding part of the reciprocating motion mechanism 20 includes a linear slider 203 and a ball guide sleeve 204. The linear slider 203 is slidably installed in the inner cavity of the inverted U-shaped base 201, and the ball guide sleeve 204 is embedded in the linear slider 203. The driving part of the reciprocating motion mechanism 20 includes a reciprocating lead screw 205 and a drive motor 206. The reciprocating lead screw 205 is threaded in the ball guide sleeve 204. The drive motor 206 is fixedly installed on the outer wall of one of the fixed side plates 202. The output shaft of the drive motor 206 passes through the outer wall of the fixed side plate 202 and extends into the inner cavity of the inverted U-shaped base 201. One end of the reciprocating screw 205 is rotatably mounted on a fixed side plate 202 on the side away from the drive motor 206, and the other end is fixedly connected to the output shaft of the drive motor 206. The balls inside the ball guide sleeve 204 mesh with the thread groove of the reciprocating screw 205.

[0026] In this embodiment, when the drive motor 206 is working, it can drive the reciprocating screw 205 through its output shaft and make the reciprocating screw 205 rotate in the inner cavity of the inverted U-shaped base 201. When the reciprocating screw 205 rotates, through cooperation with the ball guide sleeve 204, the linear slider 203 can reciprocate in the inner cavity of the inverted U-shaped base 201.

[0027] Furthermore, two L-shaped brackets 40 are provided between the inverted U-shaped base 201 and the body 101, and the two L-shaped brackets 40 are arranged symmetrically. One side wall of each of the two L-shaped brackets 40 is fixedly connected to the side wall of the inverted U-shaped base 201, and the other side wall of each of the two L-shaped brackets 40 is fixedly connected to the top of the body 101.

[0028] In this embodiment, two L-shaped brackets 40 are used to support and fix the reciprocating motion mechanism 20.

[0029] Furthermore, the gas generating part of the jet structure 30 includes a fan 301, which is fixedly mounted on the top of the body 101. The air outlet of the blower 301 is connected to an air delivery hose 302; The jetting part of the jetting structure 30 includes a gas nozzle 303, which is fixedly mounted on the bottom of the linear slider 203. The free end of the gas delivery hose 302 is connected to the gas nozzle 303.

[0030] In this embodiment, the airflow generated by the fan 301 during operation can be delivered through its jet nozzle to the gas nozzle 303 via the air delivery hose 302, and then ejected through the gas nozzle 303.

[0031] Furthermore, the gas nozzle 303 is hollow inside, and several jet micro-holes 304 are opened at the bottom; In order to optimize the connection between the air supply hose 302 and the gas nozzle 303, in this embodiment, more specifically, the gas nozzle 303 has an air inlet 305 on the side wall facing the fan 301, and the inner cavity of the air inlet 305 is connected to the inner cavity of the gas nozzle 303. The free end of the air supply hose 302 is inserted into the air inlet 305.

[0032] In this embodiment, after the airflow enters the gas nozzle 303, since the gas nozzle 303 has a number of air jet micro-holes 304, the airflow in the gas nozzle 303 can be sprayed outward in a mist form under the action of the number of air jet micro-holes 304, so as to expand the coverage range of its airflow and thereby improve the cooling range of the plastic filament.

[0033] It should be noted that the model of the geared motor 104 on the plastic drawing machine body 10 is not specifically limited, nor are the models of the drive motor 206 in the reciprocating motion mechanism 20 and the fan 301 in the jet structure 30. They can all be freely purchased from the market.

[0034] Work steps: like Figures 1-6 As shown, the base 102 on the plastic drawing machine body 10 supports the machine body 101. The reduction motor 104 and multiple drawing roller shafts 103 on the plastic drawing machine body 10 are driven by belts (not shown in the figure) to make the multiple drawing roller shafts 103 rotate synchronously to draw plastic into filaments. During plastic drawing, the cooling component is used to cool the plastic filaments. Specifically: The cooling assembly includes a reciprocating motion mechanism 20 and an air jet structure 30. Since the reciprocating motion mechanism 20 fully covers multiple drawing rollers 103, and the plastic filament is wound on multiple drawing rollers 103, after the reciprocating motion mechanism 20 and the air jet structure 30 cooperate with each other, the air jet part on the air jet structure 30 can cool the plastic filament wound on the multiple drawing rollers 103 by reciprocating motion, so as to shorten the cooling time of the plastic filament and improve the cooling effect of the plastic filament.

[0035] Specifically: The main body of the reciprocating motion mechanism 20 is used to support the sliding part and the driving part. When the driving part of the reciprocating motion mechanism 20 is working, the sliding part can move linearly on the main body. Since the jet part of the jet structure 30 is installed on the sliding part of the reciprocating motion mechanism 20, when the sliding part of the reciprocating motion mechanism 20 moves linearly, the jet part of the jet structure 30 can move synchronously with the sliding part of the reciprocating motion mechanism 20. When the jet part of the jet structure 30 moves, the airflow can blow onto the plastic filaments on the multiple drawing rollers 103 and cool them. When the drive motor 206 is working, it can drive the reciprocating screw 205 through its output shaft and make the reciprocating screw 205 rotate in the inner cavity of the inverted U-shaped base 201. When the reciprocating screw 205 rotates, it can make the linear slider 203 reciprocate in the inner cavity of the inverted U-shaped base 201 through cooperation with the ball guide sleeve 204. When the fan 301 is working, the airflow generated can be delivered through its jet nozzle to the gas nozzle 303 via the air delivery hose 302, and then ejected through the gas nozzle 303. After the airflow enters the gas nozzle 303, because the gas nozzle 303 has several air jet micro-holes 304, the airflow inside the gas nozzle 303 can be sprayed outward in a mist form under the action of the several air jet micro-holes 304, so as to expand the coverage range of its airflow and thus improve the cooling range of the plastic filament.

[0036] In summary: This equipment can improve cooling efficiency: the reciprocating motion mechanism 20 drives the jet part of the jet structure 30 to reciprocate, and the plastic filament is continuously cooled by jets, which can effectively shorten the cooling time of the plastic filament, improve cooling efficiency, and speed up the production process. This equipment can improve cooling uniformity: during the reciprocating motion of the jet section of the jet structure 30, the sprayed mist airflow covers a wider range, which can ensure that the plastic filaments on multiple drawing rollers 103 are fully cooled, avoiding the problem of uneven cooling caused by fixed-position blowing, and improving the quality of the plastic filaments. The equipment has a simple and reasonable structure: it adopts a reciprocating motion mechanism 20 composed of a reciprocating screw 205, a drive motor 206, etc., and a jetting structure 30 including a fan 301 and a gas nozzle 303. The overall structure is simple, easy to install and maintain, and reduces the production and operating costs of the equipment.

[0037] It should be noted that the different embodiments described above can be combined, substituted, and used in combination with each other.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
