[0002] The textile industry is an ancient and ever-evolving industry. With the advancement of the Industrial Revolution, the jet loom came into being. Based on traditional textile machinery, the jet loom uses high-speed jet airflow to pull the weft yarn through the warp yarn to realize the weaving process. Compared with traditional shuttle looms, this method significantly improves the weaving speed.

[0003] In the prior art, the Chinese utility model patent with authorization announcement number "CN211311744U" is specifically "a yarn inlet protection device for a jet-jet textile machine". Its specific embodiment describes that "a mounting base is installed at the yarn inlet of the jet-jet textile machine. A control plate and a telescopic cylinder are provided on the mounting base. A lower wheel frame plate is provided at the upper end of the telescopic cylinder. A first roller and a second roller are provided on the surface of the lower wheel frame plate. The yarn is accurately entered into the interior of the yarn inlet through the two rollers to prevent the yarn from rubbing against the inner wall of the yarn inlet during the transmission process."

[0004] However, there are various impurities in the textile workshop environment, such as dust and fiber debris. During the yarn feeding process, these impurities can mix into the yarn or adhere to the yarn surface, which may cause quality problems such as spots and lumps in the fabric during the weaving process.

[0022] Example 1

[0023] Please see Figures 1 to 2 This utility model provides a technical solution: an inlet protection device for a jet textile machine, including a base plate 1, three sets of first rollers 2 and second rollers 21 are provided on the surface of the base plate 1, support plates 3 are fixedly connected to both sides of the surface of the base plate 1, limit plates 11 are slidably connected to the surface of the support plates 3, a cleaning brush 6 is rotatably connected between the two limit plates 11, a connecting plate 13 is fixedly connected to the surface of the limit plates 11, a collection frame 7 is provided between the two connecting plates 13, and a toothed plate 18 is fixedly connected inside the collection frame 7;

[0024] A cleaning brush 6 is provided at the front end of the first roller 2 and the second roller 21 to clean impurities on the surface of the yarn and improve the quality of the textile production. Through the cooperation between the manual screw 9 and the limiting plate 11, the cleaning brush 6 can adapt to yarns of different thicknesses, improving the adaptability of the cleaning device. A collection frame 7 is provided at the bottom of the cleaning brush 6 to collect the impurities brushed off. A fine toothed plate 18 is provided inside the collection frame 7 to block the impurities on the cleaning brush 6, improving the collection effect and cleaning efficiency of the collection frame 7.

[0025] Example 2

[0026] Please see Figures 1 to 4Based on Embodiment 1, in order to clean the yarn passing between the first roller 2 and the second roller 21, a sliding groove 4 is provided on the surface of the support plate 3. The sliding groove 4 is a cross-shaped long groove. The limiting plate 11 is slidably connected in the sliding groove 4. Sliding blocks 12 are fixedly connected to both ends of the limiting plate 11. The sliding blocks 12 can ensure that the limiting plate 11 can only move along the surface of the sliding groove 4. The sliding blocks 12 are attached to the surface of the sliding groove 4. A motor 5 is fixedly connected to the surface of one limiting plate 11, and a manual lead screw 9 is rotatably connected to the surface of the limiting plate 11.

[0027] The surface of the manual lead screw 9 is provided with a threaded part, which is matched and connected with the threaded hole provided on the surface of the support plate 3. One end of the manual lead screw 9 extends to the top surface of the support plate 3 and is fixedly connected to the handwheel 8. The manual lead screw 9 can adjust the height of the limiting plate 11 and the cleaning brush 6, thereby ensuring close contact with the yarn and improving the cleaning effect. The surface of the other limiting plate 11 is provided with an auxiliary rod 10, and the two ends of the auxiliary rod 10 are fixedly connected to the surface of the sliding groove 4. The auxiliary rod 10 can provide support and guidance for the limiting plate 11 during the sliding process. The two limiting plates 11 are rotatably connected with a shaft 20. One end of the shaft 20 passes through the surface of one limiting plate 11 and is connected to the output end of the motor 5.

[0028] Example 3

[0029] Please see Figures 1 to 5 Based on Embodiment 2, in order to collect dust and impurities, a round rod 15 is fixedly connected to the surface of the connecting plate 13. A rubber groove is formed on the surface of the round rod 15. A rubber block 16 is fixedly connected to the surface of the rubber groove. A stop block 17 is fixedly connected to the surface of the rubber block 16. The stop block 17 has a square block structure and a bevel at one end. By setting the round rod 15 and the stop block 17, the fixing plate 14 is limited and fixed, so that the collection frame 7 can be quickly installed and fixed. The collection frame 7 can be adjusted in position along with the cleaning brush 6. The bevel at one end of the stop block 17 plays a guiding role. The bevel makes it easier for the stop block 17 to slide into the corresponding position of the fixing plate 14, which is convenient for the operator to perform installation operations and improves the assembly efficiency of the equipment.

[0030] Fixed plates 14 are fixedly connected to both ends of the collection frame 7. The surface of the fixed plate 14 has a round hole 19. The round rod 15 passes through the round hole 19 and presses the stop block 17 against the surface of the fixed plate 14. The toothed plate 18 is set on one side of the surface of the collection frame 7. The surface of the toothed plate 18 has a plurality of square holes arranged in an array. The toothed plate 18 can comb the surface of the cleaning brush 6, comb off the fiber debris on the surface of the cleaning brush 6 and leave it in the collection frame 7.

[0031] In actual use, first turn the handwheel 8, which drives the manual screw 9 to rotate. The manual screw 9 drives the limiting plate 11 to move along the surface of the sliding groove 4. Adjust the limiting plate 11 to the corresponding height according to the relative height between the first roller 2 and the second roller 21. Start the motor 5, which drives the shaft 20 to rotate, thereby rotating the cleaning brush 6. The cleaning brush 6 cleans the yarn that is about to pass through the first roller 2 and the second roller 21.

[0032] When the collection box 7 needs to be fixed, place the collection box 7 at the lower end of the cleaning brush 6, align the round hole 19 on the surface of the fixing plate 14 with the round rod 15 and move it upward. One end of the inclined surface of the stop block 17 is squeezed and shrinks into the rubber groove. At this time, the rubber block 16 changes from the original state to the compressed state. When the stop block 17 passes through the round hole 19, the rubber block 16 loses the pressure and rebounds from the compressed state to the original state, pressing the stop block 17 against the surface of the fixing plate 14.

[0033] When the cleaning brush 6 rotates to sweep away impurities, the impurities are thrown towards the collection frame 7 under the action of centrifugal force and airflow. The toothed plate 18 inside the collection frame 7 has multiple square holes, which can effectively block and collect the swept impurities, prevent impurities and fiber debris from flying again, thereby achieving effective collection and cleaning of impurities generated during the yarn feeding process and keeping the feeding area clean.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
