Description

Technical Field

[0001] This utility model relates to the technical field of fabric processing equipment, specifically a lint removal device for fabric processing. Background Technology

[0002] During the fabric weaving and finishing processes, surface lint residue directly affects the quality of the finished product. Current mainstream lint removal devices use a fixed-gap design for their cleaning rollers, which cannot adapt to the uneven texture of the fabric surface. This is especially true for high-density fabrics such as twill and satin weaves, where the coverage area is fixed and small, resulting in cleaning blind spots.

[0003] Furthermore, existing brush bristles generally use materials with uniform hardness. Hard bristles are prone to snagging and breaking yarns, while soft bristles are difficult to penetrate the gaps between fibers. The shed lint is repeatedly adhered due to electrostatic adsorption and airflow swirl, and is easily re-adsorbed onto the surface of the fabric.

[0004] Therefore, there is a need for a lint removal device for fabric processing that can solve the problems existing in the prior art. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a lint removal device for fabric processing, which solves the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a lint removal device for fabric processing, characterized in that: it includes a cleaning chamber, a cleaning cavity is provided inside the cleaning chamber, and inlet and outlet ports are provided on both ends of the cleaning chamber. A first guide shaft, a second guide shaft, and a third guide shaft are rotatably connected in sequence inside the cleaning cavity. Guide rollers are fixedly sleeved on the outer circumference of the first guide shaft, the second guide shaft, and the third guide shaft. A lint loosening component and a lint suction device are provided between the first guide shaft and the second guide shaft. An electrostatic elimination mechanism is provided between the second guide shaft and the third guide shaft. The lint loosening component includes a first lint loosening unit and a second lint loosening unit with identical structures, and the first lint loosening unit and the second lint loosening unit are arranged in opposite directions.

[0009] Preferably, the first loosening unit includes two first sliders and four fifth drive shafts. The two sides of the cleaning chamber are provided with first sliding grooves. The first sliders are slidably connected to the first sliding grooves. Two fourth cleaning shafts are rotatably connected to the first sliders. Cleaning rollers and two adjusting collars are fixedly sleeved on the outer circular surfaces of the two fourth cleaning shafts. The fifth drive shafts are rotatably connected to one side wall of the cleaning chamber. The fifth drive shafts are disposed at both ends of the first sliding grooves. Drive blocks are fixedly connected to the outer circular surfaces of the fifth drive shafts.

[0010] Preferably, the two adjusting collars are fixedly sleeved on both ends of the fourth cleaning shaft near the first slider. The outer surfaces of the adjusting collars and the driving block are provided with gear teeth, and the gear teeth of the adjusting collars and the gear teeth of the driving block are adapted to each other.

[0011] Preferably, when the driving block on one side of the first sliding groove rotates to the point where the long chord of the outer circular surface of the driving block contacts the outer circular surface of the adjusting collar, the driving block on the other side of the first sliding groove rotates to the point where the short chord of the outer circular surface of the driving block contacts the outer circular surface of the adjusting collar.

[0012] Preferably, the rotation direction of the drive blocks on both sides of the first sliding groove is opposite to the fabric conveying direction.

[0013] Preferably, the outer circumference of the cleaning roller is provided with bristles arranged in a fishbone shape, and the hardness of the bristles gradually decreases along the spine towards both sides at an oblique angle.

[0014] (III) Beneficial Effects

[0015] This utility model provides a lint removal device for fabric processing. It has the following beneficial effects:

[0016] 1. This solution uses a spacing adjustment mechanism consisting of an elliptical drive block, an adjusting collar, and a sliding component to make the cleaning roller slide back and forth along the fabric transport direction while rotating and combing the lint. This achieves the purpose of periodically and dynamically adjusting the contact spacing between the cleaning roller and the fabric, significantly improving the uniformity and coverage of lint loosening.

[0017] 2. This solution adopts a herringbone gradient bristle design (hardness decreases from the spine to the sides), so that the bristles provide strong fluffing effect on the hard main body, while the flexible branches reduce fabric damage, thereby achieving the goal of balancing efficient fluffing and protecting the integrity of the fabric surface.

[0018] 3. This solution integrates the lint loosening component, lint suction device, and static elimination mechanism along the transmission path, enabling the fabric to complete a three-stage coordinated cleaning process: lint loosening → lint suction and removal → antistatic treatment. This achieves the goal of thoroughly removing free lint and preventing its secondary adsorption. Attached Figure Description

[0024] This utility model provides a lint removal device for fabric processing, such as... Figure 1-4 As shown, it includes a cleaning chamber 11, a cleaning cavity 12, an inlet / outlet 13, a first guide shaft 14, a second guide shaft 15, a third guide shaft 16, a guide roller 17, a lint suction device 18, an electrostatic elimination mechanism 19, a first sliding groove 20, a first slider 21, a fourth cleaning shaft 22, a cleaning roller 23, an adjusting collar 24, a fifth drive shaft 25, and a drive block 26.

[0025] like Figure 1-4 As shown, a cleaning chamber 12 is provided inside the cleaning chamber 11. Inlet and outlet ports 13 are provided on both ends of the cleaning chamber 11. A first guide shaft 14, a second guide shaft 15, and a third guide shaft 16 are rotatably connected in sequence inside the cleaning chamber 12. Guide rollers 17 are fixedly sleeved on the outer circular surfaces of the first guide shaft 14, the second guide shaft 15, and the third guide shaft 16. A fluffing component and a fluff suction device 18 are provided between the first guide shaft 14 and the second guide shaft 15. An electrostatic elimination mechanism 19 is provided between the second guide shaft 15 and the third guide shaft 16. The fluff suction device 18 and the electrostatic elimination mechanism 19 are existing technologies. The fluffing component includes a first fluffing unit and a second fluffing unit with the same structure, and the first fluffing unit and the second fluffing unit are arranged in opposite directions.

[0026] The first loosening unit includes two first sliders 21 and four fifth drive shafts 25. The fifth drive shafts 25 are externally connected to a drive power source. The two sides of the cleaning chamber 12 are provided with first sliding grooves 20. The first sliders 21 are slidably connected to the first sliding grooves 20. Two fourth cleaning shafts 22 are rotatably connected to the first sliders 21. Cleaning rollers 23 and two adjusting collars 24 are fixedly sleeved on the outer circular surfaces of the two fourth cleaning shafts 22. The fifth drive shafts 25 are rotatably connected to one side wall of the cleaning chamber 12. The fifth drive shafts 25 are located at both ends of the first sliding grooves 20. Drive blocks 26 are fixedly connected to the outer circular surfaces of the fifth drive shafts 25. The cross-section of the drive blocks 26 is elliptical.

[0027] Two adjusting collars 24 are fixedly sleeved on the two ends of the fourth cleaning shaft 22 near the first slider 21. The outer circular surfaces of the adjusting collars 24 and the driving block 26 are provided with gear teeth. The gear teeth of the adjusting collars 24 and the gear teeth of the driving block 26 are matched. The rotation direction of the driving blocks 26 on both sides of the first sliding groove 20 is opposite to the fabric transmission direction.

[0028] When the driving block 26 on one side of the first sliding groove 20 rotates to the point where the long chord of the outer circular surface of the driving block 26 contacts the outer circular surface of the adjusting collar 24, the driving block 26 on the other side of the first sliding groove 20 rotates to the point where the short chord of the outer circular surface of the driving block 26 contacts the outer circular surface of the adjusting collar 24.

[0029] The outer surface of the cleaning roller 23 is provided with fishbone-shaped bristles, and the hardness of the bristles gradually decreases along the spine towards both sides.

[0030] When this solution cleans lint from the fabric, the fabric is first fed into the inlet / outlet 13 near the first guide shaft 14, passes between the two first guide shafts 14 and between the two sets of cleaning rollers 23, and then passes through the two lint suction devices 18, the two second guide shafts 15, the two static elimination mechanisms 19 and the two third guide shafts 16 in sequence before being discharged from the inlet / outlet 13 on the other side.

[0031] Then, the lint suction device 18, the static electricity elimination mechanism 19, and the fifth drive shaft 25 are activated. The fifth drive shaft 25 drives the drive block 26 to rotate. The drive block 26 drives the fourth cleaning shaft 22 to rotate through the adjusting collar 24. The fourth cleaning shaft 22 drives the cleaning roller 23 to comb and loosen the lint. Since the drive block 26 is elliptical, when the drive block 26 rotates, it pushes the adjusting collar 24 to make the first slider 21 slide back and forth along the first sliding groove 20, thereby periodically changing the distance between the cleaning roller 23 and the fabric, intermittently increasing the contact area between the cleaning roller 23 and the fabric, and improving the uniformity of loosening and combing the lint.

[0032] Finally, the lint suction device 18 provides air pressure to suck up the loosened lint on the fabric, and the static elimination mechanism 19 performs antistatic treatment on the fabric to prevent fine lint from re-adsorbing onto the fabric.

[0033] 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.
