Description

Technical Field

[0001] This invention relates to the field of recycling equipment technology, specifically to a recycling equipment for automotive plastic parts. Background Technology

[0002] With the rapid development of the automotive industry, the recycling and processing of waste automotive plastic parts is of great significance for resource recycling and environmental protection. As a core step in the recycling process, the stability and efficiency of the crushing equipment directly affect the quality of subsequent processing and economic benefits.

[0003] Existing automotive plastic parts crushing equipment mostly uses direct feeding followed by rotating crushing rollers for crushing. However, due to the irregular shape and elasticity of plastic parts, the material is prone to jumping or shifting during crushing, leading to uneven crushing, reduced efficiency, and even roller jamming. Furthermore, the feeding methods are often single-pour or simple continuous feeding, lacking intermittent control, which can easily cause blockages in the feed pipes or excessive instantaneous loads, affecting the continuous operation of the equipment. In addition, modules such as feed adjustment, pressing and fixing, and debris conveying often require their own independent power sources, resulting in complex equipment structure, high manufacturing costs, and high energy consumption. To address these technical problems, this application proposes a recycling and processing device for automotive plastic parts. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a recycling and processing device for automotive plastic parts, which solves the problems of material jumping during crushing, uneven feeding, and high energy consumption.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a recycling and processing device for automotive plastic parts, comprising: The grinding chamber has two pressure plates rotatably connected to its top side, and multiple grinding rollers rotatably connected to its inner wall. Adjacent grinding rollers are connected by a gear set. A guide plate is fixedly connected to the inner wall of the grinding chamber, and an auger is installed on the bottom side of the grinding chamber. The T-shaped support frame is fixedly connected to the rear side of the crushing chamber. A baffle is connected to the top side of the T-shaped support frame through an elastic component. A feed pipe is provided at the top of the baffle. A slider two is slidably connected to the middle of the rear side of the crushing chamber. The middle of the slider two is connected to the bottom side of the baffle through a tension component. A reduction gear is rotatably connected to the rear side of the crushing chamber. The outer circumference of the reduction gear is connected to one of the crushing rollers on the bottom side through a transmission assembly. The other crushing roller on the bottom side is connected to the drive shaft of the auger through a connector. A connecting shaft is rotatably connected to the outer wall of the crushing roller. The top end of the connecting shaft is rotatably connected to the bottom outer wall of the second slider. The top outer wall of the second slider is connected to the outer wall of the pressure plate through a connecting rod assembly.

[0006] Preferably, the gear set includes a transmission gear fixedly connected to the front end of the crushing roller, and two adjacent transmission gears are meshed together. A motor is mounted on the front side of the crushing chamber via a fixing frame, and the drive end of the motor is fixedly connected to the outer wall of one of the transmission gears.

[0007] Preferably, the elastic component includes a slide rod fixedly connected to the top side of the T-shaped support frame, the bottom end of the baffle is sleeved on the outer wall of the slide rod, a spring is sleeved on the bottom outer wall of the slide rod, and the two ends of the spring abut against the bottom side of the baffle and the top side of the T-shaped support frame, respectively.

[0008] Preferably, the tensioning assembly includes a guide wheel rotatably connected to the bottom end of the T-shaped support frame, the bottom side of the baffle and the middle end of the second slider are connected by an elastic pull rope, the elastic pull rope is disposed on the outer wall of the guide wheel, and the elastic pull rope passes through the middle end of the T-shaped support frame.

[0009] Preferably, the transmission assembly includes a drive gear fixedly connected to the rear end of one of the crushing rollers on the bottom side, and the outer periphery of the reduction gear and the drive gear are meshed together.

[0010] Preferably, the connector includes a pulley fixedly connected to the rear end of another crushing roller and the rear end of the auger drive shaft on the bottom side, and the two pulleys are connected by a drive belt.

[0011] Preferably, the connecting rod assembly includes a slider one slidably connected to the rear top of the crushing chamber, a support shaft rotatably connected to the top of the slider one, the top of the support shaft rotatably connected to the outer wall of the pressure plate, and a pull shaft rotatably connected to the top of the slider two, the top of the pull shaft rotatably connected to the outer wall of the slider one.

[0012] A method for recycling automotive plastic parts includes the following steps: Step 1: Start the motor to make multiple crushing rollers rotate synchronously and drive the auger to operate; Step 2: Add the automotive plastic parts through the feeding pipe. During the rotation of the crushing roller, the linkage pressure plate flips to press the incoming parts, while the linkage baffle moves to adjust the feeding amount. Step 3: The automotive plastic parts that are pressed and fixed by the pressure plate are crushed by multiple synchronously rotating crushing rollers; Step 4: The crushed plastic fragments are guided to the bottom of the crushing chamber by the guide plate on the inner wall of the crushing chamber; Step 5: The synchronously operating auger transports the plastic scraps to the subsequent processing stage to complete the recycling process.

[0013] Preferably, in step two, the baffle slides along the slide bar under the traction of the elastic rope and compresses or stretches the spring to change the opening of the feed pipe.

[0014] Preferably, in step one, the motor drives multiple crushing rollers to rotate via a gear set, and one of the crushing rollers transmits power via a reduction gear, while the other crushing roller transmits power to the drive shaft of the auger via a belt drive.

[0015] Working principle: After the motor starts, its drive end drives the transmission gear fixedly connected to it to rotate. Because the transmission gears at the front ends of two adjacent crushing rollers mesh with each other, multiple crushing rollers rotate synchronously. The drive gear at the rear end of one of the bottom crushing rollers meshes with the outer circumference of the reduction gear, driving the reduction gear to rotate. Simultaneously, the pulley at the rear end of the other bottom crushing roller drives the drive shaft of the auger to rotate via the transmission belt, causing the auger to run synchronously. When the crushing rollers rotate, the connecting shaft on their outer wall drives slider two to slide up and down in the middle of the rear side of the crushing chamber. The pull shaft at the top of slider two pulls slider one to slide at the top of the rear side of the crushing chamber. The support shaft at the top of slider one drives the two pressure plates on the top side of the crushing chamber to rotate, achieving pressing and limiting of the feed. The middle end of the slider is pulled by an elastic rope that moves the baffle. The elastic rope slides on the outer wall of the guide wheel, and the baffle slides up and down on the outer wall of the slide bar, compressing or stretching the spring. This allows the feeding pipe to be opened when both pressure plates are fully open, allowing automotive plastic parts to be fed into the top of the crushing chamber. When the two pressure plates begin to squeeze the automotive plastic parts, the feeding pipe is closed, ensuring uniform and controllable feeding at the feeding pipe. After entering the crushing chamber through the feeding pipe, the automotive plastic parts are pressed and fixed by the up-and-down rotating pressure plates, and then crushed by multiple synchronously rotating crushing rollers. The crushed plastic fragments are guided to the bottom of the crushing chamber by the guide plate on the inner wall of the crushing chamber, and then transported to the subsequent processing stage by a synchronously operating auger, completing the entire recycling process.

[0016] This invention provides a recycling and processing device for automotive plastic parts. It has the following beneficial effects: 1. This invention achieves automatic pressing and fixing of automotive plastic parts entering the crushing chamber by periodically flipping the pressure plate through the connecting shaft, slider two, and connecting rod assembly when the crushing roller rotates. This effectively prevents the parts from jumping or shifting during the crushing process, significantly improves the crushing stability and efficiency, and reduces the risk of crushing roller jamming.

[0017] 2. This invention utilizes the reciprocating motion of slider two to automatically adjust the opening of the feeding pipe by pulling the baffle along the slide rod via an elastic rope and spring, thereby achieving intermittent uniform feeding and avoiding blockage or uneven crushing caused by excessive feeding at one time, thus improving the continuity and reliability of equipment operation.

[0018] 3. This invention uses two motors to simultaneously drive multiple crushing rollers, pressure plate linkage mechanism and auger through gear set, reduction gear and belt drive. It can realize the integrated operation of feeding adjustment, pressing crushing and chip conveying without the need for an additional power source. The structure is compact and the linkage is efficient, which reduces the equipment manufacturing cost and operating energy consumption. Attached Figure Description

[0025] A method for recycling automotive plastic parts includes the following steps: Step 1: Start the motor 4 to make multiple crushing rollers 19 rotate synchronously and drive the auger 2 to run. In Step 1, the motor 4 drives multiple crushing rollers 19 to rotate through the gear set. One crushing roller 19 transmits power through the reduction gear 9, and the other crushing roller 19 transmits power to the drive shaft of the auger 2 through the belt drive. Step 2: Add the automotive plastic parts through the feed pipe 6. During the rotation of the crushing roller 19, the linkage pressure plate 5 flips to press the incoming parts. At the same time, the linkage baffle 7 moves to adjust the feed amount. In step 2, the baffle 7 slides along the slide bar 8 under the traction of the elastic pull rope 21 and compresses or stretches the spring 13 to change the opening size of the feed pipe 6. Step 3: The automotive plastic parts that are pressed and fixed by the pressure plate 5 are crushed by multiple synchronously rotating crushing rollers 19; Step 4: The crushed plastic fragments are guided to the bottom side of the crushing chamber 1 by the guide plate 23 on the inner wall of the crushing chamber 1; Step 5: The synchronously operating auger 2 transports the plastic scraps to the subsequent processing stage to complete the recycling process; Specifically, in step one, the drive end of motor 4 drives a transmission gear 3 to rotate. Through the meshing of adjacent transmission gears 3, all crushing rollers 19 rotate inward synchronously. At the same time, the drive gear 20 at the rear end of one of the bottom crushing rollers 19 drives the reduction gear 9 to rotate. The reduction gear 9 drives the slider 17 to move up and down reciprocally through the connecting shaft 18. The pulley 10 at the rear end of the other bottom crushing roller 19 drives the pulley 10 on the drive shaft of the auger 2 through the transmission belt 11, so that the auger 2 operates synchronously. In step two, when slider 17 moves up and down, the elastic rope 21 pulls the baffle 7 to slide along the slide bar 8. When slider 17 moves upward, the elastic rope 21 relaxes, the spring 13 pushes the baffle 7 to move upward, and the opening of the feed pipe 6 increases. When slider 17 moves upward... During the downward movement, the elastic rope 21 is tensioned, overcoming the elastic force of the spring 13 to pull the baffle 7 downward, reducing the opening of the feed pipe 6, thereby achieving intermittent uniform feeding. At the same time, the second slider 17 drives the pressure plate 5 to periodically flip downward through the pull shaft 16 and the first slider 15, pressing and fixing the plastic parts entering the top side of the crushing chamber 1 between the crushing rollers 19. In the third step, multiple crushing rollers 19 rotate synchronously to crush the pressed and fixed plastic parts. In the fourth step, the crushed plastic fragments fall under the action of gravity and are collected by the inclined guide plate 23 to the feed port of the auger 2 on the bottom side of the crushing chamber 1. In the fifth step, the auger 2 operates continuously, conveying the plastic fragments to subsequent cleaning, drying or granulation processes, completing the recycling of automotive plastic parts.
