A third connecting block is fixed to the left end of the air suction box. Two third guide rods slide on the third connecting block. The right ends of the two third guide rods are welded to the cleaning block. The cleaning block is in a rectangular block structure, and the bottom end surface of the cleaning block contacts the top end surface of the air suction box.

[0008] Further, the left ends of the two third guide rods are welded to the force-bearing block. The force-bearing block is in a rectangular block structure. A spring is sleeved on each of the two third guide rods. The left ends of the two springs contact the force-bearing block, and the right ends of the two springs contact the third connecting block. The two springs are used for the leftward reset of the cleaning block.

[0009] Further, after the air suction box moves leftward following the second connecting block, the left end surface of the force-bearing block contacts a mounting block on the left side; a collection box in a rectangular box structure is fixed to the right end surface of the air suction box, and the collection box is aligned with the cleaning block.

[0010] Further, two protrusions are welded to the front end surface of the air suction box. The two protrusions are both in a semi-cylindrical structure; a contact arm is welded to the front end surface of the force-bearing block. The contact arm is aligned with the protrusion. When the contact arm contacts the protrusion, the cleaning block moves above the collection box.

[0011] Further, a filtering assembly is installed on the left first connecting block. The filtering assembly is composed of a filtering box, a fan, an air inlet pipe, an exhaust pipe, an exhaust head, a partition board and an air outlet pipe.

[0015] Compared with the prior art, the present invention has the following beneficial effects: Flexible adjustment of the air intake position: When adjusting the position of the air intake box, drive the two first electric cylinders to expand and contract. The first connecting block will slide on the first guide rod, thereby driving the air intake box to adjust its front and back positions. Drive the motor to rotate reciprocally. Under the action of the threaded rod, the second connecting block will slide on the second guide rod to realize the left and right adjustment of the air intake box. Through the flexible adjustment of the air intake box in the front, back, left, and right directions, the air intake range of the air intake box is effectively expanded, and the impurities on the color-spun yarn fibers can be more comprehensively removed, improving the impurity removal effect and work efficiency. Compared with the traditional air intake device with a fixed position, it can cover a larger working area and adapt to the requirements of different working scenarios.

[0016] Automatic cleaning of sundries: When the air intake box moves leftward following the second connecting block and the left end face of the force-bearing block contacts the left mounting block, when continuing to drive the second connecting block to move leftward, under the blockage of the left mounting block, the cleaning block moves rightward against the elastic force of the spring. During this process, the cleaning block can push the fluff and other sundries on the top surface of the air intake box to the collection box on the right, realizing the function of automatically collecting sundries, eliminating the need for manual repeated cleaning of the sundries on the top of the air intake box, saving labor and time costs. In addition, when continuing to drive the second connecting block to move leftward until the contact arm contacts the protrusion, the air intake box will vibrate, and this vibration is transmitted to the cleaning block, which can shake the sundries attached to the cleaning block into the collection box, further ensuring the thoroughness of cleaning, keeping the top of the air intake box clean, and preventing the accumulation of sundries from affecting the air intake effect.

[0017] Efficient gas filtration: During impurity removal, start the fan, and the air intake box starts to intake air. The gas containing impurities enters the filter box through the intake pipe. Since the exhaust heads are installed on the outer wall of the exhaust pipe in a linear array, the gas is discharged through multiple exhaust heads, increasing the contact area between the gas and the filtering liquid in the filter box and improving the purification effect. At the same time, the partition in the filter box is located above the exhaust heads, and circular holes are opened on the partition. When the gas moves upward, the partition will block the gas, reducing its upward speed and dividing the gas into multiple small bubbles, further enhancing the contact effect between the gas and the filtering liquid, making the purification of the gas more thorough and efficient, effectively removing the impurities in the gas, ensuring the cleanliness of the discharged gas, meeting the environmental protection requirements, and reducing the pollution to the working environment and the atmosphere.

By adjusting the front, back, left and right of the air suction box 208, the air suction range of the air suction box 208 can be expanded, and the cleaning effect of impurities on the colored-spun yarn fibers is improved; when installing this device on the textile equipment, the distance between the two fixed seats 1 can be adjusted according to the width of the installation position.

[0025] Among them, the first guide rod 201, the first connecting block 202, the first electric cylinder 203, the second electric cylinder 204, the installation block 205, the second guide rod 206, the second connecting block 207, the air suction box 208, the motor 209 and the threaded rod 210 together constitute the adjustment assembly 2; a cleaning assembly 3 is installed on the air suction box 208, and the cleaning assembly 3, the third connecting block 301, the third guide rod 302, the cleaning block 303, the force receiving block 304, the spring 305, the collection box 306, the protrusion 307 and the contact arm 308 are composed.

[0026] A third connecting block 301 is fixed on the left end of the air suction box 208, two third guide rods 202 slide on the third connecting block 301, the right ends of the two third guide rods 302 are welded to the cleaning block 303, the cleaning block 303 is a rectangular block structure, and the bottom end face of the cleaning block 303 contacts the top end face of the air suction box 208.

[0027] Wherein, the left ends of the two third guide rods 302 are both welded to the force-bearing block 304. The force-bearing block 304 is a rectangular block structure. A spring 305 is sleeved on each of the two third guide rods 302. The left ends of the two springs 305 are both in contact with the force-bearing block 304, and the right ends of the two springs 305 are both in contact with the third connecting block 301. The two springs 305 are used for the leftward reset of the cleaning block 303.

[0028] Wherein, after the suction box 208 moves leftward following the second connecting block 207, the left end face of the force-bearing block 304 contacts with the left mounting block 205; a collecting box 306 in the shape of a rectangular box is fixed to the right end face of the suction box 208. The collecting box 306 is aligned with the cleaning block 303. During use, after the suction box 208 moves leftward following the second connecting block 207, the left end face of the force-bearing block 304 contacts with the left mounting block 205. At this time, when the second connecting block 207 is continuously driven to move leftward, under the blocking action of the left mounting block 205, the cleaning block 303 moves rightward. During the process of the cleaning block 303 moving rightward, fluff and other sundries on the top face of the suction box 208 can be pushed rightward until they are pushed to the collecting box 306. At this time, the sundries will fall into the collecting box 306 for collection, and there is no need to manually clean the sundries on the top of the suction box 208 repeatedly.

[0029] Wherein, two protrusions 307 are welded to the front end face of the suction box 208. The two protrusions 307 are both semi-cylindrical structures; a contact arm 308 is welded to the front end face of the force-bearing block 304. The contact arm 308 is aligned with the protrusion 307. When the contact arm 308 contacts with the protrusion 307, the cleaning block 303 moves to above the collecting box 306. During use, when the second connecting block 207 is continuously driven to move leftward, at this time, under the action of the contact arm 308 and the protrusion 307, the suction box 208 can be vibrated. When the vibration is transmitted to the cleaning block 303, the sundries on the cleaning block 303 can be shaken into the collecting box 306.

[0030] Among them, a filtering component 4 is installed on the leftmost first connecting block 202. The filtering component 4 is composed of a filtering box 401, a blower 402, an air inlet pipe 403, an exhaust pipe 404, an exhaust head 405, a partition plate 406 and an air outlet pipe 407. A filtering box 401 is fixed to the left end face of the leftmost first connecting block 202. The filtering box 401 is filled with a filtering liquid. A blower 402 is fixed to the top end face of the filtering box 401. An air inlet pipe 403 is connected to the air inlet end of the blower 402. The air inlet pipe 403 is connected to the air suction box 208. An exhaust pipe 404 is connected to the air outlet end of the blower 402. The exhaust end of the exhaust pipe 404 is immersed in the liquid inside the filtering box 401. During impurity removal, the blower 402 is started. At this time, air suction starts at the air suction box 208. The gas absorbed at the air suction box 208 is discharged into the filtering box 401, and filtration is achieved through the liquid inside the filtering box 401.

[0031] Among them, the exhaust pipe 404 is a cylindrical tubular structure. A number of exhaust heads 405 are installed on the outer wall of the exhaust pipe 404 in a linear array. The exhaust heads 405 are communicated with the exhaust pipe 404. During use, when the gas containing impurities is discharged through a number of exhaust heads 405, the contact effect between the gas and the filtering liquid can be improved, and thus the purification effect on the gas is improved.

[0032] Among them, a partition plate 406 is horizontally arranged inside the filtering box 401. The partition plate 406 is a rectangular plate-like structure. Circular holes are arranged in a rectangular array on the partition plate 406. The partition plate 406 is located above the exhaust heads 405. When the gas containing impurities is discharged through the exhaust heads 405 and contacts the liquid for purification, and then the gas moves upward. At this time, blocked by the partition plate 406, the upward movement speed of the gas can be reduced, and through the circular holes on the partition plate 406, the gas can be divided into multiple small bubbles, improving the contact effect between the gas and the filtering liquid, and thus improving the purification effect of the gas.

[0033] Embodiment Two: On the basis of Embodiment One, it further includes: An air outlet pipe 407 is welded to the top of the filtering box 401. The air outlet pipe 407 is communicated with the inside of the filtering box 401. The air outlet pipe 407 is a bent pipe structure. During use, the purified gas will be discharged through the air outlet pipe 407. And because the air outlet pipe 407 is a bent pipe structure, when not in use, the probability of dust entering the inside of the filtering box 401 through the air outlet pipe 407 can be reduced.

[0034] The specific usage method and function of this embodiment: During impurity removal, the fan 402 is started. At this time, suction begins at the suction box 208. The gas absorbed at the suction box 208 is discharged into the filter box 401 through the exhaust head 405 and contacts the liquid in the filter box 401 for filtration and purification. Then the gas moves upward. At this time, blocked by the partition plate 406, the upward movement speed of the gas can be reduced. And through the circular holes on the partition plate 406, the gas can be divided into multiple small bubbles. Finally, the small bubbles emerge from the water surface and burst. After bursting, the gas is discharged through the air outlet pipe 407. When adjusting the position of the suction box 208, driving the two first electric cylinders 203 to expand and contract can adjust the front and rear positions of the suction box 208. Driving the motor 209 to rotate reciprocally can, under the drive of the threaded rod 210, achieve the left and right adjustment of the suction box 208. Through the front, rear, left, and right adjustment of the suction box 208; at the same time, when the suction box 208 moves leftward following the second connecting block 207, the left end face of the force-receiving block 304 contacts one of the left mounting blocks 205. At this time, continuing to drive the second connecting block 207 to move leftward, blocked by one of the left mounting blocks 205, the cleaning block 303 moves rightward. During the process of the cleaning block 303 moving rightward, sundries such as fluff on the top surface of the suction box 208 can be pushed rightward until it is pushed to the collection box 306. Continuing to drive the second connecting block 207 to move leftward, at this time, under the action of the contact arm 308 and the protrusion 307, vibration of the suction box 208 can be achieved. When the vibration is transmitted to the cleaning block 303, the sundries on the cleaning block 303 can be shaken off into the collection box 306.
