[0002] After yarn is extruded from the extruder, it needs to be quickly cooled. Currently, fans are typically used to blow cold air toward the yarn to achieve this cooling effect. However, this cooling area is large, and the cold energy dissipates quickly, resulting in insignificant cooling of the introduced cold energy and a high temperature in the area, which affects the cooling effect on the yarn. Utility Model Content

The lower end of the top plate is lifted and lowered with an air guide plate, and the air guide plate and the upper end of the cold air chamber form a cooling channel to reduce the cooling area and improve the cooling effect.

[0006] As a further solution of the utility model:

[0007] The cold air plate is provided with a straight blowing hole in the middle to blow directly on the passing yarn. Side air blocks are installed obliquely and symmetrically on both sides of the cold air plate. The side air blocks are provided with side blowing holes connected to the cold air chamber to cool the yarn and blow the cold air toward the side of the extruder.

[0008] As a further solution of the utility model:

[0009] The side of the air guide plate facing the extruder is provided with an arc-shaped portion, and the arc-shaped portion is provided with corresponding grooves corresponding to the yarn to direct the cold air to the lower end of the cold air chamber.

Guide rods are positioned around the air deflector, sliding through sleeves around the top plate to limit the air deflector's position. The pneumatic cylinder controls the movement of the air deflector, increasing the cooling channel size as the yarn emerges, facilitating yarn passage, and adjusting the cooling channel's volume to enhance cooling efficiency.

[0016] Compared with existing technologies, the present invention offers the following advantages: a cooling mechanism mounted on a stand on one side of the extruder utilizes an evaporator to dissipate cold energy, which is then applied to the yarn via a cold air plate to rapidly cool the yarn. The air guide plate and cold air chamber form a cooling channel, narrowing the cooling area, preventing cold energy from escaping, lowering the temperature in the local area, and improving the cooling effect. Cold air is guided by the air guide plate to the lower end of the cold air chamber and re-inhaled by the fan, achieving cold energy recycling, improving cold energy utilization efficiency, and reducing cold energy dissipation.

DETAILED DESCRIPTION

[0022] In order to make the technical means for realizing the present invention, the creative features, the objectives and the effects thereof easier to understand, the present invention is further described below with reference to specific illustrations.

[0023] like Figures 1 to 4 As shown,

[0024] This embodiment provides a yarn extrusion cooling mechanism, comprising an extruder 1, a stand disposed on one side of the extruder 1, and a cooling mechanism mounted on the stand. The stand comprises a bottom plate 11 and side plates 12 disposed on both sides of the bottom. The cooling mechanism comprises a cold air chamber 2 mounted on the side plates 12 and a refrigeration device disposed at the outer end of the bottom plate 11 and connected to the cold air chamber 2. Top plates 13 are further disposed on top of the side plates 12 on both sides.

[0025] The cold air chamber 2 is provided with several groups of cold air plates 21 corresponding to the extruder 1 to cool the extruded yarn through the cold air plates 21. The lower end of the top plate 13 is lifted and installed with an air guide plate 22. The air guide plate 22 and the upper end of the cold air chamber 2 form a cooling channel to reduce the cooling area and improve the cooling effect.

[0026] In this embodiment, a direct blowing hole 23 is provided in the middle part of the cold air plate 21 to blow directly on the passing yarn. Side wind blocks 24 are installed obliquely and symmetrically on both sides of the cold air plate 21. The side wind blocks 24 are provided with side blowing holes 25 connected to the cold air chamber 2 to cool the yarn and blow the cold air toward the side of the extruder 1.

[0027] In this embodiment, an arc-shaped portion 26 is provided on the side of the air guide plate 22 facing the extruder 1, and a corresponding groove 27 is opened in the arc-shaped portion 26 corresponding to the yarn to direct the cold air to the lower end of the cold air chamber 2. An air inlet assembly is provided at the lower end of the cold air chamber 2 to realize the recycling of cold energy, reduce the temperature around the yarn, improve the cooling effect, and reduce energy consumption.

[0028] In this embodiment, an evaporation tube 28 is coiled in the cold air chamber 2, and the evaporation tube 28 is connected to a cooling mechanism through a pipeline. The cooling mechanism includes a compressor 14 and a condenser installed at the lower end of the base plate 11 to perform circulating refrigeration.

[0029] The air intake assembly is distributed and installed at the bottom of the cold air chamber 2. The air intake assembly includes an air inlet fan 3 and a filter box 31 arranged outside the air inlet fan 3. A filter plate 32 is inserted and installed on the filter box 31 to filter the introduced gas.

[0030] In this embodiment, a cylinder 29 is mounted on the top plate 13 to control the elevation of the air guide plate 22. Guide rods 20 are provided around the air guide plate 22. The guide rods 20 slide through sleeves around the top plate 13 to limit the position of the air guide plate 22. The cylinder 29 controls the elevation of the air guide plate 22 to increase the cooling channel size as the yarn emerges, facilitating yarn passage, and facilitating adjustment of the cooling channel volume to enhance cooling efficiency.

[0031] The working principle of the present invention is as follows: the cylinder 29 adjusts the air guide plate 22 to rise to increase the distance between the air guide plate 22 and the cold air chamber 2, so that personnel can easily pass the extruded yarn through the cooling channel, and then lowers the air guide plate 22 to narrow the cooling area. The fan guides the cold energy emitted by the evaporation tube 28 through the cold air plate 21, and the cold air guided by the straight blowing hole 23 on the cold air plate 21 directly cools the yarn, and the side blowing hole 25 cools the yarn laterally and pushes the cold air to flow to one side of the extruder 1 to cool the front end of the yarn. Finally, it is introduced into the bottom of the cold air chamber 2 through the air guide plate 22, and the air inlet component re-sucks the cold air into the cold air chamber 2 to improve the cold energy utilization efficiency and reduce the escape of cold energy.
