DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1: Please refer to Figures 1 to 4 The present embodiment provides a plastic wire drawing machine for making fishing nets, including a wire drawing machine 1. A cooling trough 3 is provided at the end of a machine head 2 of the wire drawing machine 1. Plastic particles are put into the feed port of the wire drawing machine 1, melted and heated, and extruded by a screw in the wire drawing machine 1. They reach the machine head 2 and are drawn into a plurality of wires, which fall into the cooling trough 3. Cooling water is poured into the cooling trough 3, and the wires are cooled and shaped.

[0023] In this embodiment, a left cover 4 and a right cover 5 are respectively provided on both sides of the outer wall of the middle part of the machine head 2. The left cover 4 and the right cover 5 are fixed to each other to form an outer cover. A closed chamber is formed between the inner wall of the outer cover and the inner wall of the machine head 2. The left cover 4 is located on the side close to the wire drawing machine 1, and the right cover 5 is located on the side away from the wire drawing machine 1. The design of the outer cover enables the chamber to collect heat dissipated by the machine head 2.

[0024] In this embodiment, an air inlet pipe 7 is formed in the middle of the left cover 4, and an air outlet pipe 8 is formed in the middle of the right cover 5. An integrated fan 9 is fixed to the inner wall of the air inlet pipe 7. The end of the air outlet pipe 8 is connected to a diverter cover 10. The side of the diverter cover 10 close to the air outlet pipe 8 is circular, and the side of the diverter cover 10 away from the air outlet pipe 8 is rectangular. The overall volume of the diverter cover 10 gradually increases from the side close to the air outlet pipe 8 to the side away from the air outlet pipe 8. Four air guide hoses 11 are fixed at equal intervals on the side of the diverter cover 10 away from the air outlet pipe 8, and the end of the air guide hose 11 away from the diverter cover 10 is connected to an air guide cover 12.

[0025] In this embodiment, the integrated fan 9 works to allow outside air to enter the chamber, and the hot air in the chamber is discharged from the air outlet pipe 8 to the diverter cover 10, and then reaches the four air guide hoses 11 and is discharged from the four air guide covers 12.

[0026] In this embodiment, the inner wall of the cooling trough 3 is connected to two first guide rollers 16 which rotate in sequence from the side close to the wire drawing machine 1 to the side away from the wire drawing machine 1, and a plurality of air guide covers 12 are located between the two first guide rollers 16. A group of second guide rollers 17 are rotatably installed on the top surface of the cooling trough 3, and the second guide rollers 17 are located on the side of the air guide cover 12 away from the wire drawing machine 1.

[0027] In this embodiment, the drawn silk thread passes around the two first guide rollers 16 in turn, and then is transmitted vertically upward to reach the second guide roller 17. This group of second guide rollers 17 is distributed in two layers, and each layer of second guide rollers 17 is arranged at equal intervals along the length direction of the cooling trough 3. When the silk thread reaches the second guide roller 17, it reciprocates up and down in a wave-like manner, passes around all the second guide rollers 17 in turn, and finally extends out of the periphery of the cooling trough 3. The wind guide cover 12 is directly facing the group of second guide rollers 17, so that the hot air blown out is blown to the outside of the silk thread that reciprocates around the second guide rollers 17, accelerating the evaporation of moisture on the outer wall of the silk thread. The provision of the second guide roller 17 extends the path of the silk thread flowing above the cooling trough 3, so that the silk thread has enough time to drain in the cooling trough 3. Combined with hot air drying, the probability of cooling water being carried out by the silk thread and falling on the ground and other production and processing equipment is greatly avoided, saving cooling water, avoiding the pollution of the production environment by cooling water, and damage to subsequent silk thread processing equipment.

[0028] In this embodiment, a guide rod 13 is fixed to the side of the top surface of the cooling groove 3 facing away from the wire drawing machine 1, and a sliding sleeve 14 is fixed to the bottom of the air guide cover 12. The sliding sleeve 14 is slidably connected to the outer wall of the guide rod 13. The cross-section of the guide rod 13 is rectangular, and a bolt 15 is threadedly connected to the side wall of the sliding sleeve 14 through a threaded hole, and the end of the bolt 15 is in contact with the outer wall of the guide rod 13.

[0029] In this embodiment, the air guide hood 12 is supported by the guide rod 13 and the sliding sleeve 14, so that the air guide hood 12 can face the silk thread, and the spacing of the air guide hood 12 can be adjusted according to the amount of wire drawing by the machine head 2 to ensure that hot air can always be blown evenly. The bolt 15 can be turned for adjustment. After the adjustment is complete, the bolt 15 can be turned again to press against the outer wall of the guide rod 13 to position the air guide hood 12.

[0030] For example 2, please refer to Figure 5 This embodiment provides a further technical solution based on the first embodiment. The fixing component includes a friction washer 6 fixed to one end of the sliding sleeve 14. The inner wall of the friction washer 6 abuts against the outer wall of the guide rod 13. Compared with the first embodiment, this technology can not only position the air guide cover 12, but also reduce the adjustment steps of the air guide cover 12. When adjusting the position of the air guide cover 12, the sliding sleeve 14 can be directly slid. After the sliding sleeve 14 stops, the friction washer 6 is used to limit the position of the sliding sleeve 14.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
