Description

Technical Field

[0001] This utility model relates to the field of nylon recycled material processing technology, and more specifically to a crushing device for nylon recycled material processing. Background Technology

[0002] With increasing environmental awareness, the disposal of plastic waste has become a global concern. Nylon, as a common engineering plastic, can cause serious environmental pollution if large quantities of waste nylon products are not treated properly. Crushing equipment can break waste nylon products into smaller particles or flakes, which facilitates subsequent transportation, storage and processing, reducing the volume of waste and environmental pollution.

[0003] When existing crushing equipment for nylon recycling processes crushes materials, the materials tend to accumulate at the crushing inlet. Due to the lack of an effective guidance and dispersion mechanism, they often gather together and block the outlet, making it difficult for subsequent materials to pass through smoothly. This situation not only affects the normal operation of the equipment but also greatly reduces the crushing efficiency.

[0004] Furthermore, many of these devices on the market do not have a dedicated screening component. This means that once the material has been initially crushed, additional steps are required to remove impurities or non-compliant parts. Without built-in screens or other forms of filtration, operators have to manually separate these substandard materials, which undoubtedly increases labor intensity and may affect the consistency of the final product quality.

[0005] Therefore, in order to solve the above problems, this application provides a crushing device for processing recycled nylon. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a crushing device for processing recycled nylon to solve the problems existing in the background art.

[0008] Preferably, the housing assembly includes a main housing, a material drop frame, a fixing plate, and support feet, wherein the material drop frame is fixedly installed at the bottom of the main housing, the fixing plate is fixedly installed on the front and rear sides of the bottom of the main housing, and the support feet are fixedly installed in pairs on the bottom sides of the fixing plate.

[0009] Preferably, the crushing assembly includes a crushing box, a feeding hopper, a crushing roller, and a first motor. The crushing box is fixedly installed on the main housing, the feeding hopper is fixedly installed on the crushing box, the first motor is fixedly installed on the front side of the crushing box, the crushing roller is disposed inside the crushing box, and the two ends of the crushing roller are rotatably engaged with the crushing box. The drive shaft of the first motor moves through the crushing box and is fixedly sleeved on the crushing roller. When material is fed into the feeding hopper, the drive shaft of the first motor drives the crushing roller to rotate, and the material is crushed and brought into the left cavity of the crushing box by the recessed toothed blade design on the crushing roller.

[0010] Preferably, the transmission assembly includes a pusher box, a second motor, a first gear, a second gear, a rotating roller, a first transmission gear, a transmission belt, and a second transmission gear.

The second gear is fixedly sleeved on the rotating roller. The two ends of the rotating roller movably pass through the pusher box and are fixedly sleeved on the first transmission gear. The second transmission gear is located to the left of the first transmission gear and rotatably engaged with the side wall of the pusher box. The transmission belt meshes and wraps between the first and second transmission gears. At this time, the drive shaft of the second motor drives the first gear, and through the meshing action between the first and second gears, drives the second gear and the rotating roller fixedly sleeved on the second gear, thereby driving the first transmission gear to rotate. Subsequently, under the action of the transmission belt, the second transmission gear is driven to rotate.

[0011] Preferably, the pushing assembly includes a push block, a limiting block, a fixing block, a first hinge, a second hinge, and a third hinge. The push block is slidably connected to a material feeding box on both sides. The limiting block is fixedly installed on the material feeding box and positioned directly above the push block. The fixing block is fixedly installed on the right side of the push block. The first hinge is fixedly installed on the side wall of the fixing block. One end of the second hinge is hinged to the first hinge, and the other end is hinged to the third hinge. The end of the third hinge furthest from the second hinge is fixedly sleeved onto the extension end of the second transmission gear. At this time, the third hinge rotates around the main shaft of the second transmission gear under the action of the transmission assembly, driving the second hinge, which is engaged at its left end, to rotate. The first hinge is also driven by the second hinge. Through the limiting relationship of the sliding connection between the push block and the material feeding box, the first hinge drives the push block and the limiting block to perform a reciprocating retraction action.

[0012] Preferably, the screening assembly includes a vibrating motor, a transmission rod, a positioning block, a spring, a first screen plate, a second screen plate, and a limiting rod. The vibrating motor is fixedly installed on the inner wall of the top of the main housing. The output end of the vibrating motor is fixedly sleeved with the transmission rod.

The positioning block is set on the upper and lower sides of the first screen plate and the second screen plate respectively and is fixedly sleeved with the transmission rod. The spring is movably sleeved with the transmission rod and is set between the first screen plate, the second screen plate and the corresponding positioning block. The left end of the first screen plate and the second screen plate is rotatably sleeved with the limiting rod. The two ends of the limiting rod are rotatably locked onto the inner wall of the main housing. At this time, the vibration shaft of the vibrating motor drives the transmission rod and the first screen plate and the second screen plate movably sleeved on the transmission rod to vibrate. The spring plays a certain degree of buffering role while limiting their movement. At this time, large particles are retained on the first screen plate and discharged through the right end outlet under the action of vibration and gravity. The remaining smaller particles fall above the second screen plate and are discharged through the outlet on the lower right side.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] When the device crushes the material, the transmission component drives the pushing component, which pushes the material to the side closer to the crushing roller. This design greatly improves the crushing efficiency and avoids the problem of clogging the crushing port. At the same time, the crushed material falls to the screening component and is screened and separated by the vibrating motor and various screen plates before being discharged. This design facilitates the subsequent processing of the material. Attached Figure Description

[0027] The working principle of this utility model is as follows: When using the device, material is fed into the feed hopper 202. At this time, the transmission shaft of the first motor 204 drives the crushing roller 203 to rotate. The material is crushed by the recessed toothed blades on the crushing roller 203 and brought into the left cavity of the crushing box 201. The crushed material then falls into the main housing 101. During the crushing process, the transmission shaft of the second motor 302 drives the first gear 303. Through the meshing between the first gear 303 and the second gear 304, the second gear 304 and the rotating roller 305 fixedly sleeved on the second gear 304 are driven to rotate.

The third hinge 406 rotates around the main shaft of the second transmission gear 308 under the action of the second transmission gear 308, and drives the second hinge 405, which is locked at its left end, to rotate. The first hinge 404 is also driven by the second hinge 405. At this time, through the limiting relationship of the sliding connection between the push block 401 and the push box 301, the first hinge 404 drives the push block 401 and the limiting block 402 to reciprocate and retract. At this time, the material falling into the crushing box 201 is pushed to the side close to the crushing roller 203 by the push block 401. After the crushed material falls into the main housing 101, it is located above the first screen plate 505. At this time, the vibration motor 501 vibration shaft drives the transmission rod 502 and the first screen plate 505 and the second screen plate 506 movably sleeved on the transmission rod 502 to vibrate. The spring 504 plays a certain degree of buffering role while limiting it. At this time, large particles are retained on the first screen plate 505 and discharged through the right end outlet under the action of vibration and gravity. The remaining smaller particles fall into the second screen plate 506 and are discharged through the outlet on the lower right side.
