Description

Technical Field

[0001] This invention relates to the field of textile recycling technology, specifically to a pretreatment device for scraps of waste textiles. Background Technology

[0002] Patent publication number CN115319823B discloses a textile waste scrap fabric recycling and crushing machine, including a base plate, a crushing mechanism installed on the top of the base plate, a pushing mechanism installed on the top of the crushing mechanism, and a shielding mechanism installed on the outside of the crushing mechanism. The crushing mechanism includes a processing box 3, a support frame, a first electric push rod, an upper shearing blade, a tray, a discharge hopper, a lower shearing blade, and a column. The fabric is placed on the tray. When the fabric on the top of the tray moves between the upper and lower shearing blades, the upper and lower shearing blades can perform multiple shearing and crushing operations on the fabric with the cooperation of the first electric push rod. Since the upper and lower shearing blades do not rotate, jamming during the crushing process is avoided. With the cooperation of the pushing mechanism, the arc plate can push the fabric between the upper and lower shearing blades, while the flat push plate can push the crushed fabric into the discharge hopper.

[0003] Existing technologies often use water rinsing to remove dust from waste textiles. However, dust that is tightly attached to the fibers or has penetrated them is difficult to remove directly with water, resulting in poor cleaning effect. After processing, waste textiles will form piles of varying thickness on the conveyor belt, making it difficult for hot air to penetrate and causing uneven drying, which in turn affects the drying effect and efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a pretreatment device for waste textile scraps.

[0005] The technical problem solved by this invention is: 1. Dust that is tightly attached to or has penetrated into the fibers of waste textiles is difficult to clean;

[0006] 2. Waste textiles of varying thicknesses stacked on the conveyor belt cannot be heated evenly, affecting the drying effect and efficiency.

[0007] This invention can be achieved through the following technical solution: a dust cover is fixedly installed on the front side of the mounting frame; a processing box is fixedly installed on the top of the mounting frame near the dust cover; a conveyor belt is installed between the dust cover and the top of the processing box; a beating mesh plate that moves up and down is provided inside the dust cover; a crushing component is provided at the bottom of the inner cavity of the processing box; a spraying component is provided near the crushing component above the inner cavity of the processing box; support plates are fixedly installed on the top of the mounting frame at positions corresponding to the bottom sides of the processing box; two opposing push plates are slidably installed between the two support plates; a brush is fixedly installed at the bottom of the push plate; a conveyor belt is provided on the mounting frame near the brush below; and a heating plate is fixedly installed on the rear side of the top of the mounting frame.

[0008] A further technical improvement of the present invention is that the structure that causes the beating mesh plate to move up and down includes a fixed plate fixedly installed inside the dust cover, a sliding plate slidably installed through the fixed plate, a beating mesh plate fixedly installed at the bottom of the sliding plate, several springs fixedly installed between the beating mesh plate and the fixed plate, a sliding groove opened at the top of the sliding plate, and a U-shaped rod rotatably installed through the dust cover and slidably connected through the sliding groove. The U-shaped rod and the conveyor belt are driven by a pulley.

[0009] Furthermore, dustproof tassels are fixedly installed on both sides of the bottom of the dust cover top plate, and the bottom of the dustproof tassels is attached to the top of the conveyor belt. A vacuum cleaner is fixedly installed at the bottom of the dust cover.

[0010] Furthermore, the crushing assembly includes two opposing crushing rollers rotatably mounted inside the processing chamber, and several serrations are fixedly installed on both sides of the inner wall of the processing chamber at positions corresponding to the crushing rollers.

[0011] Furthermore, the structure that causes the two push plates to move toward each other includes a slide plate 2 that is slidably connected through both sides of the dust cover, a connecting plate 2 that is fixedly installed at the bottom of each of the two slide plates 2, and two mutually symmetrical push-pull plates 3 that are rotatably installed at the bottom of the connecting plate 2. The ends of the two push-pull plates 3 that are away from the connecting plate 2 are respectively rotatably connected to the top of the two push plates 2.

[0012] Furthermore, the structure that causes the slide plate 2 to move up and down includes a pair of rotating plates that are rotatably mounted on both sides of the mounting frame near the processing box. One of the rotating plates is driven by a pulley to the rotating shaft of the crushing roller. A push-pull plate 2 is rotatably mounted on the end of the rotating plate away from the rotating shaft. The end of the push-pull plate 2 away from the rotating plate is rotatably connected to one side of the connecting plate 2. A connecting plate 3 is rotatably mounted on each pair of push-pull plates 2.

[0013] Furthermore, the spraying assembly includes a drain ring pipe fixedly installed at the top of the inner cavity of the treatment tank, with several nozzles fixedly connected to the outer peripheral wall of the drain ring pipe. A water storage tank is fixedly installed on one side of the treatment tank, and a one-way inlet valve is fixedly connected between the water storage tank and the drain ring pipe to facilitate the unidirectional flow of liquid from the water storage tank to the drain ring pipe. Several piston cylinders connected to the drain ring pipe are fixedly installed on the other side of the treatment tank. A piston rod is slidably installed through the side of each piston cylinder away from the drain ring pipe. A connecting plate is fixedly installed at the end of each piston rod away from the piston cylinder. Push-pull plates are rotatably installed on both sides of the connecting plate. The ends of the two push-pull plates away from the connecting plate are rotatably connected to the tops of two sliding plates.

[0014] Furthermore, an extrusion roller is rotatably mounted on the front side of the mounting frame near the heating plate, and the bottom of the outer peripheral wall of the extrusion roller is in contact with the top of the second conveyor belt.

[0015] Furthermore, both conveyor belts are made of stainless steel to prevent rusting caused by prolonged contact with water, which could contaminate the scraps of waste textiles.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This application first uses a reciprocating beating screen to beat the scraps of waste textiles to remove the dust attached to them, and then conveys them to the crushing roller for crushing. At the same time, clean water is rinsed on the scraps undergoing the crushing process through a drainage ring pipe to clean them, thereby improving the cleaning effect.

[0018] 2. In this application, the scraps of waste textiles are crushed and washed in the processing box and fall to the front side of the top of the conveyor belt. Then, two opposing push plates drive the brush to flatten the scraps piled up here, and then convey them to the heating plate for drying, which improves the uniformity of drying and improves the drying efficiency.

[0019] 3. This application uses a conveyor belt to push the flattened scrap material fragments to the bottom of the extrusion roller, thereby squeezing out excess moisture from the scrap material and reducing the burden of subsequent heating and drying. Attached Figure Description

[0028] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0029] Please see Figure 1-3 As shown, this embodiment provides a pretreatment device for waste textile scraps, including a mounting frame 1. A dust cover 2 is fixedly installed on the front side of the mounting frame 1. A processing box 3 that runs vertically through the top of the mounting frame 1 is fixedly installed near the dust cover 2. A conveyor belt 4 is installed between the top of the dust cover 2 and the top of the processing box 3. Dust-proof tassels 5 are fixedly installed on both sides of the bottom of the top plate of the dust cover 2. The bottom of the dust-proof tassels 5 is in contact with the top of the conveyor belt 4. A fixing plate 6 is fixedly installed on the inside of the dust cover 2. A sliding plate 7 is slidably installed through the fixing plate 6. A beating net plate 8 is fixedly installed at the bottom of the sliding plate 7. Several springs 9 are fixedly installed between the beating net plate 8 and the fixing plate 6. A sliding groove 10 is opened at the top of the sliding plate 7. A U-shaped rod 11 that is rotatably installed through the dust cover 2 and slidably connected to the sliding groove 10 is rotatably installed through the dust cover 2. The U-shaped rod 11 is driven by a pulley to the conveyor belt 4. A vacuum cleaner 12 is fixedly installed at the bottom of the dust cover 2.

[0030] When the conveyor belt 4 is conveying, it drives the U-shaped rod 11 to rotate synchronously via the pulley. The rotating U-shaped rod 11 drives the slide plate 7 to move up and down vertically. At this time, the outer peripheral wall of the U-shaped rod 11 slides back and forth in the slide groove 10 to correct the positional relationship between the U-shaped rod 11 and the slide plate 7. When the slide plate 7 drives the striking mesh plate 8 to move upward, the striking mesh plate 8 will compress several springs 9 towards the fixed plate 6, so that the springs 9 are in a state of tension. When the slide plate 7 moves upward... When the 7-driven beating screen plate 8 moves downward, the tension of several springs 9 is released, and they press down on the beating screen plate 8, causing the beating screen plate 8 to pound on the top of the conveyor screen plate 1. When the beating screen plate 8 beats the waste scraps on the conveyor screen plate 1, the dust attached to the surface of the waste scraps falls off. The dust kicked off from the waste scraps is confined in the inner cavity of the dust cover 2 by the dust cover 2 and the dust tassel 5. Then, by starting the vacuum cleaner 12, the dust is sucked out from inside the dust cover 2.

[0031] Please see Figure 1-2 and Figure 4 As shown, two opposing crushing rollers 13 are rotatably installed inside the processing box 3. A drive motor is provided on the processing box 3 to drive the crushing rollers 13. Several saw teeth 14 are fixedly installed on both sides of the inner wall of the processing box 3 at positions corresponding to the crushing rollers 13. A second conveyor belt 15, made of stainless steel, is installed inside the mounting frame 1. A drain ring pipe 16 is fixedly installed above the crushing rollers 13 on the inner side of the processing box 3. Several nozzles with spray surfaces pointing towards the crushing rollers 13 are fixedly connected to the outer periphery of the drain ring pipe 16. A water storage tank 17 is fixedly installed on one side of the processing box 3. A water inlet pipe is fixedly connected to the water storage tank 17. When the water in the water storage tank 17 is used up, clean water can be poured into the water storage tank 17 through the water inlet pipe. The water storage tank 17 and the drain ring pipe 16 are connected... A one-way inlet valve is fixedly connected between the 6 tanks to facilitate the unidirectional flow of liquid from the water storage tank 17 to the drain ring pipe 16. Several piston cylinders 18 connected to the drain ring pipe 16 are fixedly installed on the other side of the treatment tank 3. A piston rod 19 is slidably installed on the side of the piston cylinders 18 away from the drain ring pipe 16. A connecting plate 20 is fixedly installed on the end of the piston rod 19 away from the piston cylinder 18. Slide plates 21 are slidably installed on both sides of the treatment tank 3. The mounting frame 1 is equipped with a transmission mechanism 22 that causes the two slide plates 21 to move up and down synchronously when the crushing roller 13 rotates. Push-pull plates 23 are rotatably installed on the top of the two slide plates 21. The ends of the two push-pull plates 23 away from the slide plates 21 are rotatably connected to the two sides of the connecting plate 20 respectively.

[0032] After the waste scraps are conveyed to the dust cover 2 by the conveyor belt 4, the waste scraps are crushed by two opposing rotating crushing rollers 13 and several saw teeth 14 inside the dust cover 2. The crushed waste scraps fall to the top of the conveyor belt 15 at the bottom of the dust cover 2. At the same time, the sliding plate 21, which moves up and down, drives the connecting plate 20 to push and pull several piston rods 19 towards the piston cylinder 18 through the push-pull plate 23. When the piston rods 19 are pulled out of the piston cylinders 18, the piston cylinders 18 will suck the liquid in the water tank 17 into the drain pipe. When the piston rods 19 are pushed into the piston cylinders 18, the liquid in the drain pipe will be squeezed onto the crushing rollers 13 through several nozzles to clean the waste scraps being crushed by the crushing rollers 13.

[0033] The transmission mechanism 22 includes a connecting plate 221 fixedly installed on the bottom of two sliding plates 21. A pair of rotating plates 222 are rotatably installed on both sides of the mounting frame 1. One of the rotating plates 222 is connected to the rotating shaft of one of the crushing rollers 13 by a belt drive. A push-pull plate 223 is rotatably installed on the end of the rotating plate 222 away from the rotating shaft. The end of the push-pull plate 223 away from the rotating plate 222 is rotatably connected to one side of the connecting plate 221. A connecting plate 3 224 is rotatably installed between each pair of push-pull plates 223.

[0034] When the shredding roller 13 drives one of the rotating plates 222 to rotate via the pulley, the rotating plate 222 will drive the push-pull plate 223 to push and pull the connecting plate 221 up and down. The push-pull plate 223 will then drive the other push-pull plate 223 to move synchronously via the connecting plate 3 224, thereby causing the two push-pull plates 223 to push and pull the two connecting plates 221 synchronously, so that the two sliding plates 21 move up and down synchronously.

[0035] Support plates 24 are fixedly installed on both sides of the top of the mounting frame 1 near the processing box 3. Two mutually symmetrical push plates 25 are slidably installed between the two support plates 24. Brushes 26 are fixedly installed on the bottom of the two push plates 25. Two mutually symmetrical push-pull plates 27 are rotatably installed on the bottom of the two connecting plates 221. The ends of the two push-pull plates 27 away from the connecting plate 1 20 are rotatably connected to the top of the two push plates 25. When the connecting plate 221 moves upward, it will drive the two push plates 25 to move closer to each other through the two mutually symmetrical push-pull plates 27, and vice versa.

[0036] Please see Figure 1-2As shown, a squeezing roller 28 is rotatably mounted on the mounting frame 1 near the rear side of the two push plates 25. The bottom of the outer peripheral wall of the squeezing roller 28 is in contact with the top of the conveyor belt 15. A heating plate 29 is fixedly mounted on the mounting frame 1 near the rear side of the squeezing roller 28. A heater is installed on the mounting frame 1 to heat the heating plate 29. The squeezing roller 28 is used to squeeze the waste scrap material conveyed to the bottom of the conveyor belt 15 to squeeze out the moisture in the waste scrap material. Then, the waste scrap material is conveyed to the bottom of the heating plate 29 by the conveyor belt 15 to dry it.

[0037] In use, the waste scraps to be processed are first placed in the front conveying area of ​​the conveyor belt 4. The conveyor belt 4 then transports the waste scraps into the processing box 3. During this process, the beating mesh plate 8 beats the waste scraps transported into the dust cover 2 to remove internal dust. The dust is then sucked out of the dust cover 2 by the vacuum cleaner 12. After the beaten waste scraps are transported into the processing box 3, two opposing crushing rollers 13, in conjunction with several saw teeth 14 on the inner wall of the processing box 3, crush the scraps. During this process, the drain ring pipe 16 continuously sprays clean water onto the crushed waste scraps to further clean them. The remaining dust in the material is cleaned, and the cleaned and crushed waste scraps fall to the front conveying area of ​​the second conveyor belt 15. At this time, two opposing push plates 25 drive the brushes 26 at their bottoms to push the crushed waste scraps piled up here to the top of the second conveyor belt 15. Then, the flattened waste scraps are conveyed to the rear of the waste scrap box by the second conveyor belt 15. When the waste scraps pass through the extrusion rollers 28, they are squeezed by the extrusion rollers 28 to squeeze out the water inside. Then, they are dried by the heating plate 29 to complete the processing of the waste scraps. Finally, the processed waste scraps are conveyed to the designated location by the second conveyor belt 15.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
