In this utility model, the cutter achieves the effect of flattening the high-elasticity rigid cotton low-melting-point fibers by compression, and also adsorbs metal residues within the high-elasticity rigid cotton low-melting-point fibers, preventing excessive wear of the cutter, and improving the dryness of the high-elasticity rigid cotton low-melting-point fibers, thereby enhancing the working efficiency of the cutter. However, in the existing technology, metal residues are separated from chemical fibers by magnetic adsorption. After long-term operation, a large amount of metal will be generated on the magnetic adsorption component, which will affect the subsequent metal separation effect.

[0004] Therefore, a cutting device for fiber processing is needed to ensure effective metal separation. Utility Model Content

[0005] The technical problem to be solved by this utility model is: to overcome the shortcomings of the prior art and provide a cutting device for fiber processing that ensures the metal separation effect.

The two rotating rollers are distributed along the fiber conveying direction and are rotatably connected to the worktable. The conveyor belt is connected through the two rotating rollers, one of which is connected to a drive system to achieve the rotation of the rotating roller. The two ends of the conveyor belt are connected to form a closed loop structure. The magnet is located within the closed loop structure. The magnet and the collection box are both fixedly connected to the worktable. The collection box is located below the conveyor belt and has an opening at the top. The collection box is biased towards the side of the magnet closer to the heating roller.

[0008] Preferably, a push rod is movably mounted on the collection box. The push rod is arranged horizontally and is perpendicular to the direction of fiber conveying. Both ends of the push rod are connected to a moving unit, which drives the push rod to move back and forth along the direction of fiber conveying. A push block is provided at the bottom of the push rod, and the push block is located inside the collection box.

[0009] Preferably, multiple push blocks are provided, and the multiple push blocks are distributed at intervals along the length direction of the push rod.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] This utility model discloses a cutting device for fiber processing. It uses the attraction of a magnetic block to concentrate metal onto a conveyor belt, and then the movement of the conveyor belt causes the metal to fall into a collection box. This avoids excessive metal accumulation on the magnetic components and ensures effective metal separation. Secondly, the reciprocating movement of a pusher block within the collection box ensures that the metal is evenly distributed within the box, preventing it from becoming too concentrated and overflowing. Furthermore, the intermittent impact of an elastic sheet against a fixed block causes the collection box to vibrate, which further facilitates the even distribution of metal within the box.

[0032] like Figure 1-8As shown, a fiber processing cutting device in this embodiment includes a worktable 1, on which a conveying system 2 is provided to realize the linear conveying of chemical fibers. A heating roller 3 and a cutting mechanism 4 are provided on the worktable 1. The heating roller 3 and the cutting mechanism 4 are distributed along the chemical fiber conveying direction. The heating roller 3 is used to heat the chemical fibers and a heating wire is provided inside the heating roller 3. The cutting mechanism 4 is used to perform the cutting action of the chemical fibers. A separation mechanism 5 is provided on the worktable 1. The separation mechanism 5 is located on the side of the heating roller 3 away from the cutting mechanism 4.

[0033] The cutting mechanism 4 includes a blade holder 41 and a blade body 42. The blade holder 41 is fixedly mounted on the workbench 1. A lifting cylinder 43 is mounted on the blade holder 41 and connected to the blade body 42. The lifting cylinder 43 drives the blade body 42 to rise and fall. A guide tube 44 is fixedly mounted on the blade holder 41. A guide rod 45 is coaxially mounted on the guide tube 44 and fixedly mounted on the blade body 42. When the chemical fiber is transported to the area below the blade body 42, the lifting cylinder 43 drives the blade body 42 to descend, causing the blade body 42 to cut the chemical fiber. The descent of the blade body 42 drives the guide rod 45 to descend synchronously on the guide tube 44. Through the cooperation of the guide rod 45 and the guide tube 44, the blade body 42 is guided during its rise and fall. After the chemical fiber is cut, the lifting cylinder 43 drives the blade body 42 to rise and reset.

[0034] The separation mechanism 5 includes a conveyor belt 51, a magnet block 52, a collection box 53, and two rotating rollers 54. The two rotating rollers 54 are distributed along the fiber conveying direction and are rotatably connected to the worktable 1. The conveyor belt 51 is connected through the two rotating rollers 54, and one of the rotating rollers 54 is connected to the drive system. The drive system enables the rotating roller 54 to rotate. The two ends of the conveyor belt 51 are connected to form a closed loop structure. The magnet block 52 is located inside the closed loop structure. The magnet block 52 and the collection box 53 are both fixedly connected to the worktable 1. The collection box 53 is located below the conveyor belt 51 and has an opening at the top. The collection box 53 is biased towards the side of the magnet block 52 that is closer to the heating roller 3.

[0035] During operation, when the chemical fiber on the conveying system 2 moves to the area below the magnet 52, the magnet 52 generates an adsorption force on the metal residue, causing the metal residue to adhere to the lower outer surface of the conveyor belt 51. Here, the metal residue mainly consists of iron, cobalt, and nickel. At the same time, the drive system rotates the rotating roller 54, which in turn drives the conveyor belt 51 to rotate. The rotation of the conveyor belt 51 causes the metal adsorbed on the conveyor belt 51 to move towards the infeed roller. When the metal moves between the magnet 52 and the heating roller 3, the adsorption force of the magnet 52 on the metal decreases, and the metal falls into the collection box 53 due to its own weight, thus achieving metal collection. This avoids the problem of too much metal being generated on the magnetic adsorption component, which would affect the metal separation effect.

[0036] Of course, in order to improve the reliability of conveying metal by the conveyor belt 51, the outer surface of the conveyor belt 51 is provided with anti-slip texture, which increases the friction between the metal and the conveyor belt 51.

[0037] A push rod 55 is movably mounted on the collection box 53. The push rod 55 is horizontally arranged and perpendicular to the fiber conveying direction. Both ends of the push rod 55 are connected to a moving unit 56. The moving unit 56 drives the push rod 55 to move back and forth along the fiber conveying direction. Multiple push blocks 57 are provided at the bottom of the push rod 55. The push blocks 57 are spaced apart along the length of the push rod 55. Each push block 57 is located inside the collection box 53. When metal falls into the collection box 53, the moving unit 56 drives the push rod 55 to move back and forth, which in turn drives the push blocks 57 to move back and forth. The push blocks 57 push the metal in the collection box 53, so that the metal is evenly distributed in the collection box 53, preventing the metal from being too concentrated and overflowing from the collection box 53.

[0038] The moving unit 56 includes a lead screw 561, which is parallel to the direction of fiber conveying. One end of the lead screw 561 is rotatably connected to the worktable 1, and the other end of the lead screw 561 is driven to a motor 562. A slider 563 is threaded onto the lead screw 561, and the slider 563 is fixedly connected to a push rod 55. The motor 562 drives the lead screw 561 to reciprocate, thereby causing the slider 563 to reciprocate on the lead screw 561 and driving the push rod 55 to reciprocate synchronously.

[0039] The collection box 53 is provided with multiple fixing blocks 58, which are spaced apart along the fiber conveying direction. The push rod 55 is provided with an elastic piece 59, which is inserted between two fixing blocks 58. The thickness of the elastic piece 59 is less than the distance between two adjacent fixing blocks 58. During the reciprocating movement of the push rod 55, the elastic piece intermittently impacts the fixing blocks 58. Because the elastic piece 59 is elastic, it can avoid jamming. The impact of the elastic piece 59 causes the collection box 53 to vibrate, which facilitates the further uniform distribution of metal in the collection box 53.

[0040] In summary, the metal is concentrated on the conveyor belt 51 by the attraction of the magnetic block 52, and then falls into the collection box 53 by the movement of the conveyor belt 51. This avoids the accumulation of too much metal on the magnetic components and ensures the metal separation effect. Secondly, the reciprocating movement of the push block 57 in the collection box 53 makes the metal evenly distributed in the collection box 53, preventing the metal from being too concentrated and overflowing from the collection box 53. In addition, the intermittent impact of the elastic sheet 59 on the fixed block 58 causes the collection box 53 to vibrate, which facilitates the further even distribution of the metal in the collection box 53.

[0041] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
