Description

Technical Field

[0001] This utility model belongs to the field of nonwoven fabric technology, specifically a waste recycling device for nonwoven fabric production. Background Technology

[0002] Nonwoven fabric, also known as non-woven textile, is a fabric made by bonding, fusing, or needle-punching textile fibers or filaments without traditional spinning and weaving processes. It is lightweight, breathable, low-cost, and easily biodegradable, and its functions can be adjusted according to needs. Nonwoven fabric production workshops generate some waste during the production process, which needs to be crushed and recycled. This requires the use of nonwoven fabric waste recycling equipment in the production workshop.

[0003] In existing technologies, non-woven fabric waste may develop wrinkles during the accumulation process. As a result, when the waste is crushed, the wrinkled parts are folded together, causing uneven crushing of particles and incomplete crushing.

[0004] Therefore, this utility model provides a waste recycling device for nonwoven fabric production. Utility Model Content

[0005] In order to overcome the shortcomings of existing technologies and solve the problem that non-woven fabric waste may form wrinkles during the accumulation process, resulting in uneven and incomplete crushing of the crushed particles due to the folded parts being folded together during the crushing process.

A crushing roller is fixedly connected to the first rotating rod, and the crushing roller is located inside the chassis. The chassis is provided with a power assembly that drives the pair of first rotating rods to rotate. The flattening assembly includes a second rotating rod connected to a fixed frame via an adjustment component. A rotating roller is fixedly connected to the second rotating rod, and a pair of spiral rubber rings are fixedly connected to the rotating roller and are arranged opposite to each other.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 4 As shown in the figure, a waste recycling device for nonwoven fabric production according to an embodiment of the present invention includes a chassis 1, which serves as the main frame of the device and has an overall rectangular structure. A feed hole 2 is provided on the side wall of the chassis 1, and a fixing frame 25 is fixedly connected to the side wall of the chassis 1, located below the feed hole 2. The overall structure is "U". A recycling mechanism is provided on the chassis 1, which includes: a crushing component, including a pair of first rotating rods 3 rotatably connected between opposite side walls of the chassis 1, with the two ends of the first rotating rods 3 passing through both sides of the chassis 1 respectively. A crushing roller 4 is fixedly connected to the first rotating rod 3 and is located inside the chassis 1. A power component is provided on the chassis 1 to drive the pair of first rotating rods 3 to rotate; a flattening component, including a second rotating rod 5 connected to the fixing frame 25 through an adjustment component, a rotating roller 6 fixedly connected to the second rotating rod 5, and a pair of spiral rubber rings 7 fixedly connected to the rotating roller 6 and arranged opposite to each other; a linkage component is provided on the first rotating rod 3 to drive the second rotating rod 5 to rotate; and a wind pressure component is provided on the top of the chassis 1 for pushing nonwoven fabric.

[0018] The power assembly includes a first gear 8 fixedly connected to one end of the first rotating rod 3 located on the outside of the housing 1. A pair of first gears 8 are meshed with each other. A motor 9 is fixedly connected to the side wall of the housing 1 via an L-shaped rod. The core power source of the equipment is the servo motor 9. The rotation speed of the first rotating rod 3 can be adjusted by controlling the speed of the motor 9, thereby controlling the crushing efficiency of the crushing roller 4 and the flattening speed of the flattening assembly. The output end of the motor 9 is driven and connected to one end of the first rotating rod 3.

[0019] The adjustment assembly includes sliding slots 10 on both sides of the fixed frame 25, with sliding blocks 11 slidably connected in the sliding slots 10. The second rotating rod 5 is rotatably connected to a pair of sliding blocks 11. First fixed blocks 12 are fixedly connected to both sides of the fixed frame 25. Electric push rods 13 are fixedly connected to the top of the first fixed blocks 12. The telescopic end of the electric push rods 13 is fixedly connected to a second fixed block 14. The second fixed block 14 is fixedly connected to the side wall of the sliding block 11.

[0020] The linkage assembly includes a pair of first bevel gears 15 fixedly connected to the first rotating rod 3, a pair of first L-shaped blocks 16 rotatably connected to the first rotating rod 3, and a telescopic rod 17 rotatably connected to the first L-shaped blocks 16 through a first rotating hole. The telescopic rod 17 is composed of a sleeve rod and a sliding rod, and can only extend and retract, but cannot rotate. A second bevel gear 18 is fixedly connected to the base end of the telescopic rod 17, and the first bevel gears 15 and the second bevel gears 18 are meshed and connected.

[0021] A pair of second L-shaped blocks 19 are fixedly connected to the second rotating rod 5. The second L-shaped blocks 19 are rotatably connected to the telescopic end of the telescopic rod 17 through the second rotating hole. A third bevel gear 20 is fixedly connected to the telescopic end of the telescopic rod 17. A fourth bevel gear 21 is fixedly connected to the second rotating rod 5. The third bevel gear and the fourth bevel gear 21 are meshed and connected.

[0022] During operation, the relatively set spiral rubber rings 7 can flatten and unfold the wrinkled waste, avoiding the waste from overlapping and causing the crushing roller 4 to "bite" or produce large pieces of uncrushed waste after crushing. At the same time, the spiral rubber rings 7 are made of soft material and will not damage the non-woven fabric fibers, ensuring that the crushed waste still retains good recycling value. This solves the problem in the existing technology that non-woven fabric waste may form wrinkles during the accumulation process, which causes uneven crushing particles and incomplete crushing due to the wrinkled parts being folded together during the crushing process.

[0023] The air pressure assembly includes a fan 22 fixed to the top of the housing 1 by a pair of support rods. The fan 22 is fixed between opposite side walls of the housing 1. The output end of the fan 22 is connected to a rectangular air nozzle 23. Inclined plates 24 are fixed to opposite side walls of the housing 1. The pair of inclined plates 24 are inclined toward the center of the pair of crushing rollers 4.

[0024] During operation, the blower 22 and the rectangular nozzle 23 work together with the inclined plate 24 to form directional air pressure, which can provide a stable downward thrust for thin non-woven fabric waste, preventing the waste from "floating" or getting stuck between the feed hole 2 and the crushing roller 4 during the conveying process. It can guide the airflow along the conveying direction, further assisting the waste to move forward and reducing the conveying jamming rate.

[0025] Working principle: For non-woven fabric waste of different thicknesses, the flattening height is adjusted by adjusting the component: The electric push rod 13 is activated, and its telescopic end drives the second fixed block 14 to move up and down, thereby pulling the sliding block 11 to slide in the sliding groove 10 of the fixed frame 25; the sliding block 11 drives the second rotating rod 5 and the outer rotating roller 6 to rise and fall synchronously until the distance between the rotating roller 6 and the subsequent conveying path is suitable for the thickness of the waste material, avoiding excessive tightness that damages the waste material or excessive looseness that prevents flattening. The operator feeds the non-woven fabric waste through the feed hole 2 on the side wall of the machine box 1. At this time, the power component is activated: the motor 9 drives one of the first rotating rods 3 to rotate through the output end. Since the outer sides of both first rotating rods 3 are fixed with meshing first gears 8, one first rotating rod 3 will drive the other first rotating rod 3 to rotate in the opposite direction (forming opposing rotation) through gear transmission. While the first rotating rod 3 is rotating, the flattening component is driven to work through the linkage component: the first rotating rod 3 The first bevel gear 15 on the telescopic rod 17 meshes with the second bevel gear 18 at the base of the telescopic rod 17, converting the horizontal rotational force into the longitudinal rotation of the telescopic rod 17. The telescopic end of the telescopic rod 17 meshes with the fourth bevel gear 21 on the second rotating rod 5 through the third bevel gear 20, further driving the second rotating rod 5 and the rotating roller 6 to rotate. A pair of oppositely arranged spiral rubber rings 7 on the outer layer of the rotating roller 6 will "pull" the fed waste material to both sides during the rotation process, so as to flatten the waste material and avoid the waste material wrinkles causing incomplete subsequent crushing. The flattened waste material continues to be conveyed into the machine box 1. At this time, the wind pressure component is activated: the fan 22 at the top of the machine box 1 sends high-pressure airflow into the rectangular air nozzle 23 through the output end. The air nozzle blows air downwards, which, together with the inclined plate 24 fixed to the inner side wall of the machine box 1 (guiding the airflow direction), forms a downward wind pressure thrust to ensure that the waste material is stably attached to the conveying path and avoids conveying jams due to the waste material being too light or airflow disturbance. After the waste enters the machine casing 1, it is crushed by a pair of counter-rotating crushing rollers 4 (fixed to the first rotating rod 3). Since the crushing rollers 4 rotate synchronously with the first rotating rod 3 and the two crushing rollers 4 rotate in opposite directions, they will generate shearing and squeezing action on the waste, crushing the flattened waste into uniform small pieces, thus completing the pre-treatment and recycling of the waste (the crushed pieces can be used for subsequent regeneration processing).
