Description

Technical Field

[0001] This utility model relates to the field of yarn processing technology, specifically a pre-wetting device for vortex spinning. Background Technology

[0002] In vortex spinning, the yarn formed from fibrous materials such as flax after spinning needs to maintain a certain moisture content during the subsequent twisting process to improve the yarn's flexibility and processing quality. Traditional pre-wetting methods often use direct water spraying, but this can lead to uneven moisture distribution on the yarn surface and over-wetting, resulting in poor pre-wetting effectiveness. Utility Model Content

[0003] The purpose of this invention is to provide a pre-wetting device for vortex spinning, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: the pre-wetting device for vortex spinning includes a water storage tank: The water storage tank has several through slots that penetrate the water storage tank, and the upper part of the water storage tank has a top slot that communicates with the through slots. The water storage tank is equipped with a main water pipe, and a number of branch water pipes are installed on the main water pipe. The number of branch water pipes is the same as the number of through channels. A water storage tank is installed on the branch water pipes, and the two ends of the water storage tank are provided with slots. A water pump is installed on the outside of the water storage tank. The water pump has an inlet port and an outlet port. The inlet port and outlet port of the water pump are connected to the water storage tank and the main water pipe respectively through pipes. A C-shaped mounting cylinder is rotatably connected to a through groove on one side of the water storage tank. Two C-shaped ring plates are provided on the mounting cylinder. The side wall of the water storage tank is located between the two ring plates. A C-shaped elastic pad is provided on the mounting cylinder and between the water storage tank and the ring plates. A sponge block is provided inside the mounting cylinder, and a guide groove is provided on the sponge block.

[0005] Preferably, the opening of the guide groove is V-shaped.

[0006] Preferably, a stepped groove is provided on the inner side of the ring plate at one end of the mounting cylinder. The stepped groove includes an inner groove and an outer groove. The sponge block abuts against the inner groove, and the inner diameter of the outer groove is smaller than the diameter of the sponge block.

[0007] Preferably, a diversion plate is provided inside the water storage tank and directly above the water distribution pipe.

[0008] Preferably, through holes are provided on both sides of the upper surface of the diverter plate.

[0009] The beneficial effects of this utility model are: By setting up a water storage tank and a water pump to supply water at low pressure, the linen yarn is allowed to fully contact the overflow water in the water storage tank, improving the uniformity of pre-wetting. At the same time, by setting up a wetted sponge block, excess water on the linen yarn can be scraped off to prevent over-wetting. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] Example 1: The yarn processed by the pre-wetting device is flax yarn 1. After the flax raw material is processed by vortex spinning, flax yarn 1 is formed. When the flax yarn 1 is twisted in the subsequent process, it needs to have a certain amount of moisture. Therefore, the pre-wetting device is needed to pre-wet the flax yarn 1.

[0018] like Figure 1-5As shown, when pre-wetting the flax yarn 1, the flax yarn 1 is first pulled from the top groove 4 of the water tank 2 into the through groove 3 of the water tank 2, and then the flax yarn 1 is guided through the guide groove 14 into the sponge block 13. The function of the sponge block 13 is to wipe off excess water from the surface of the flax yarn 1, but it does not need to absorb a lot of water from the flax yarn 1. Therefore, the sponge block 13 needs to be soaked with water first. After the flax yarn 1 passes through the sponge block 13, the outermost ring plate 11 rotates the mounting cylinder 10 and the inner sponge block 13 by about 180°, thereby preventing the flax yarn 1 from jumping out from the top groove 4. The two ends of the water tank 2 are respectively equipped with yarn guides. The flax yarn 1 passes through the yarn guides at both ends and the water tank 2 at the same time. The yarn guides can fix the position of the flax yarn 1 when passing through the water tank 2, which is convenient for subsequent pre-wetting treatment.

[0019] After the flax yarn 1 is laid out, it is in a moderately stretched state. When twisting the flax yarn 1, it will be pulled to move. Before the flax yarn 1 moves, the water pump 9 needs to be started in advance. When the water pump 9 is started, it can transport the water stored in the water storage tank 2 to each branch water pipe 6 through the pipes and the main water pipe 5. The water pressure delivered by the water pump 9 is relatively low, so the water flowing out of the branch water pipe 6 does not spray straight upward, but overflows into the water storage tank 7. When the water in the water storage tank 7 flows back into the water storage tank 2 from the slots 8 at both ends of the water storage tank 7, the liquid level in the water storage tank 7 is about 2-3 mm higher than the lowest point of the slot 8. The linen yarn 1 passing through the water storage tank 7 is located about 1-2 mm above the lowest point of the tank opening 8. Therefore, the linen yarn 1 can be covered by the overflowing water in the water storage tank 7. The water storage tank 7 can increase the contact time between the linen yarn 1 and the water, and improve the pre-wetting effect of the linen yarn 1. After the linen yarn 1 is pre-wetted by the water in the water storage tank 7, it passes through the sponge block 13. The sponge block 13 can scrape off the excess water attached to the linen yarn 1. At the same time, since the sponge block 13 itself is already wet, it will only scrape off the excess water attached to the linen yarn 1 and will not take away the moisture inside the linen yarn 1, thus reducing the moisture loss of the linen yarn 1.

[0020] When in use, the sponge block 13 is not compressed, and the friction between the sponge block 13 and the linen yarn 1 is low. Therefore, when the linen yarn 1 passes through the sponge block 13, it will not cause serious wear to the sponge block 13. At the same time, the sponge block 13 can be made of wear-resistant materials, such as wear-resistant polyurethane.

[0021] The elastic pad 12 is made of rubber or silicone and is located between the water tank 2 and the ring plate 11. The elastic pad 12 is in a compressed state to increase the friction between the ring plate 11 and the water tank 2, thereby increasing the rotational resistance of the mounting cylinder 10 in the through groove 3. This means that the mounting cylinder 10 will only rotate significantly when the operator actively drives it to rotate through the ring plate 11. Vibrations during equipment use will not cause significant changes in the position of the mounting cylinder 10.

[0022] Example 2: like Figure 4 As shown, the upper end of the guide groove 14 is set in a V shape to facilitate the flax yarn 1 to enter the guide groove 14 and enter the center position of the sponge block 13.

[0023] Example 3: like Figure 4 As shown, since the inner diameter of the outer groove 15 is smaller than the diameter of the sponge block 13, when the excess water on the flax yarn 1 is continuously scraped off by the sponge block 13, the water in the sponge block 13 can flow into the water storage tank 2 on its own, instead of flowing to the outside of the water storage tank 2, which is beneficial to protecting the working environment.

[0024] Example 4: like Figure 3 , 5 As shown, the diversion plate 16 is used to block the water in the water distribution pipe 6 to prevent it from spraying directly upwards, ensuring that the water can stably enter the water storage tank 7 from the water distribution pipe 6.

[0025] Example 5: like Figure 3 As shown, the through hole 17 on the diversion plate 16 allows the water flowing out of the water pipe 6 to be transferred to the middle of the water storage tank 7 relatively quickly, avoiding the situation where the water in the water storage tank 7 is low in the middle and high on both sides, and ensuring that the flax yarn 1 can be effectively immersed in the water.
