Description

Technical Field

[0001] The utility model relates to the technical field of spinning production equipment, and particularly relates to a spinning device for recycled non-woven fabrics. Background Art

[0002] In the manufacturing process of non-woven fabrics, it is necessary to blow air to multiple continuous filaments melt-spun from a spinning nozzle. However, while blowing cold air, the molten spinning may be cooled and solidified, resulting in nozzle blockage.

[0003] For a non-woven fabric spinning device with the Chinese patent publication number CN117535808A and the name of a non-woven fabric spinning device, the cooling and solidified nozzle is conducted by setting a thimble. However, this method may damage the internal roughness of the nozzle, resulting in poor spinning quality in subsequent spinning. At the same time, the thimble may also solidify in the nozzle, causing equipment losses.

[0004] Based on this, in order to ensure the normal use of the nozzle and keep the nozzle unblocked when the equipment is not working, this design proposes a spinning device for recycled non-woven fabrics. Content of the Utility Model

[0012] 1. In the present utility model, by providing a coil and a spinning cavity, when the device stops working, the molten spinning will solidify due to the temperature drop, and the spinning remaining at the nozzle will clog the nozzle. Therefore, when the device stops working, air is introduced through the air pipe to utilize the air flow to extrude the remaining molten spinning. At the same time, the coil approaches the nozzle to work and heats the nozzle to ensure the molten spinning state inside the nozzle, facilitating the gas to blow out the remaining spinning.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following further clearly and completely describes the present utility model in conjunction with the accompanying drawings of the specification, but the protection scope of the present utility model is not limited thereto.

[0018] According to Figure 1 As shown, a spinning device for recycled non-woven fabric includes: a base 1, a spinning device 2, a support frame 3, a moving block 4, and a coil 5. The structure of the base 1 is a rectangular structure. Among them, the spinning device 2 is installed on the upper surface of the base 1, the support frame 3 is installed on the left side of the spinning device 2, the spinning device 2 and the support frame 3 are on the same straight line, the moving block 4 is arranged inside the front end of the support frame 3, the coil 5 is installed under the moving block 4, and the moving block 4 is controlled by a control chip.

[0019] According to Figure 2As shown, specifically, the spinning device 2 includes: a feed pipe 21, a material storage chamber 22, a nozzle chamber 23, a support rod 24, a nozzle 25, a material storage rack 26, a nozzle 27, and a ventilation pipe 28. The structure of the material storage rack 26 is an "L" shape. One end of the material storage rack 26 is fixed on the base 1, and the other end is connected to the nozzle 27. The left side of the material storage rack 26 is connected to the feed pipe 21. A material storage chamber 22 is arranged on the upper part of the material storage rack 26. The right end of the material storage chamber 22 is connected to the nozzle 27. A support rod 24 is fixed below the nozzle 27. A nozzle chamber 23 is arranged inside the nozzle 27. The structure of the nozzle 27 is a cylindrical structure. A nozzle 25 is installed on the right side of the nozzle 27. The nozzles 25 are evenly distributed on the nozzle 27. A ventilation pipe 28 is connected to the upper part of the nozzle 27.

[0020] According to Figure 3 As shown, specifically, the structure of the nozzle 25 is a long tube structure. The nozzle 25 includes: a nozzle tube 251, a wide chamber section 252, a narrow chamber section 253, and an arc-shaped nozzle opening 254. The outside of the nozzle 25 is the nozzle tube 251. A chamber section is arranged inside the nozzle 25. The chamber section on the left side of the nozzle 25 is the wide chamber section 252. The right side of the wide chamber section 252 is the narrow chamber section 253. The right side of the narrow chamber section 253 is the arc-shaped nozzle opening 254. The inside of the nozzle 25 becomes narrower from wide, which can accelerate the flow rate of the molten spinning filament, thereby ensuring the production rate of the spinning filament. At the same time, the design of the arc-shaped nozzle opening 254 can ensure the smoothness of the spun filament and prevent it from sticking to the right end face of the nozzle 25, further preventing the blockage of the nozzle 25.

[0021] Specifically, the inside of the nozzle tube 251 gradually becomes narrower from wide.

[0022] Specifically, the inner surface of the nozzle tube 251 is smooth.

[0023] Working principle:

[0024] A regenerated non-woven fabric spinning device includes: a base 1, a spinning device 2, a support frame 3, a moving block 4, and a coil 5. When working, the molten spinning filament will be transported to the material storage chamber 22 through the feed pipe 21. After the pressure in the material storage chamber 22 increases, the molten spinning filament will pass through the nozzle chamber 23 and be ejected through the nozzle 25 to carry out spinning. After the work is completed, the device will stop working. At this time, the molten spinning filament will remain in the device. At this time, ventilation is continued in the device through the ventilation pipe 28 to extrude the spinning filament. At the same time, by moving the coil 5, the coil 5 is sleeved on the nozzle 25 to heat the nozzle 25 and heat the solidified spinning filament back to the molten state. With the cooperation of the ventilation pipe 28 and the coil 5, the residual spinning filament is extruded to prevent the nozzle 25 from being blocked due to solidification after cooling, ensuring the smoothness of the next use, and at the same time protecting the nozzle 25 and prolonging the service life of the nozzle 25.
