Description

Technical Field

[0001] This utility model relates to the field of plastic crushing and screening technology, specifically to a high-efficiency crushing and screening device for automotive plastic parts. Background Technology

[0002] In the recycling of automotive plastic parts, efficient crushing and screening are crucial steps. Traditional equipment suffers from incomplete crushing, low screening accuracy, and material mixing, especially for multi-material composite parts such as bumpers and dashboards, where tough plastics can become entangled in the blades and hard plastics can be unevenly crushed. With the increasing lightweighting of automobiles and the growing use of plastics, the demand for recycling has surged, creating an urgent need for integrated equipment that combines multi-stage crushing, precise screening, and impurity separation to improve recycling efficiency and material utilization.

[0003] Utility model patent CN221736768U discloses a plastic crushing device with a screening structure, including a cylinder and a mounting plate. The cylinder is fixedly mounted to the top of the mounting plate via mounting angles. A screening mechanism is provided in the lower half of the inner cavity of the cylinder. The screening mechanism includes fixed plates that are bolted to the perimeter of the inner cavity of the cylinder. Springs are bolted to the top of each fixed plate, and screen plates are bolted to the top of each spring. A vibrating motor is fixedly mounted at the center of the bottom of the screen plate. A lifting mechanism is provided at the top of the cylinder. The screen plates automatically screen plastic fragments of different sizes, facilitating subsequent classification and processing. The vibrating motor causes the screen plates to shake, thereby improving screening efficiency and preventing screen plate clogging, which helps ensure the continuity of plastic crushing and screening processing.

[0004] Although the plastic crushing device with a screening structure can easily improve screening efficiency by shaking the screen plate and effectively avoid screen plate clogging, the device still has the following problems in actual use: relying solely on the rotation of the crusher results in poor crushing effect for some larger or harder plastic parts, and with only one screen plate, the screening accuracy is low. Therefore, we propose a high-efficiency crushing and screening device for automotive plastic parts. Utility Model Content

[0005] In view of the shortcomings of the existing technology, such as poor crushing effect and low screening accuracy, it is desirable to provide a high-efficiency crushing and screening device for automotive plastic parts.

Two extrusion rollers are horizontally and rotatably mounted in opposite directions within the crushing chamber. Several multi-layered extrusion blades are fixedly mounted on the outer walls of the extrusion rollers. A cutting roller is rotatably engaged with the crushing chamber below the center between the two extrusion rollers. Several multi-layered cutting blades are fixedly mounted on the outer walls of the cutting roller. Several inclined screens are arranged sequentially in a Z-shape from top to bottom inside the screening chamber.

The extrusion block is offset from the extrusion blade on the same side of the extrusion roller. The extrusion blades on the two extrusion rollers are offset, and the extrusion blades on the outer sidewalls of the two extrusion rollers that are close to each other are offset and locked together. The two inner sidewalls of the cutting chamber opposite to the cutting blade are fixedly connected with blades.

[0011] In both of these settings, the crushing motor drives two crushing gears to achieve synchronous rotation in opposite directions.

[0012] According to the technical solution provided in the embodiments of this application, the top surface of the screening box is provided with a feed pipe that communicates with the bottom end of the cutting cavity. The feed pipe is located above the higher end of the highest screen. The mesh size of the screens decreases from top to bottom. The screening box is slidably engaged with a chip collection drawer near the bottom end below the lowest screen.

[0013] In this setup, multiple layers of screens are used to grade and screen the plastics, and a waste collection drawer is used to collect the waste.

[0015] In this setting, a return spring is used to provide elastic support for the screen.

[0016] According to the technical solution provided in the embodiments of this application, the distance between the outer wall of the actuating shaft and the corresponding bottom surface of the screen is less than the width of the actuating plate, and the number of actuating plates fixedly installed on each actuating shaft is at least two and they are distributed in a ring at equal intervals;

[0018] According to the technical solution provided in the embodiments of this application, the actuating shafts located at the top and bottom ends all penetrate the same side wall of the screening box and are coaxially connected to actuating wheels. The remaining actuating shafts all penetrate the same side wall of the screening box and are coaxially connected to second double-groove transmission wheels. The actuating wheels and adjacent second double-groove transmission wheels, as well as two adjacent second double-groove transmission wheels, are connected by actuating transmission belts, and adjacent actuating transmission belts do not contact each other.

[0019] According to the technical solution provided in the embodiments of this application, a toggle motor is fixedly installed on the outside of one side wall of the screening box, and the output shaft of the toggle motor and one of the toggle shafts are coaxially connected.

[0020] In both of these settings, a toggle motor drives several toggle plates to rotate synchronously.

[0037] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] Please see Figures 1-7 A high-efficiency crushing and screening device for automotive plastic parts includes a crushing box 1 and a screening box 2 that are interconnected vertically. Two horizontally rotatable extrusion rollers 11 are mounted inside the crushing box 1. Several multi-layered extrusion blades 111 are fixedly mounted on the outer wall of each extrusion roller 11. A cutting roller 12 is rotatably engaged below the center between the two extrusion rollers 11 in the crushing box 1. Several multi-layered cutting blades 121 are fixedly mounted on the outer wall of the cutting roller 12. Inside the screening box 2, several inclined screens 24 are arranged in a Z-shape from top to bottom. Support boxes 23 are installed at the bottom of both ends of each screen 24 on the two opposite inner walls of the screening box 2. The screening box 2 also contains... There is a toggle assembly 3, which includes several toggle shafts 31, the same number as the screens 24, located below the middle of the corresponding screens 24. Several toggle plates 32 are fixedly installed on the outer wall of the toggle shafts 31. The two opposite side walls of the screening box 2 are each equipped with a discharge pipe 22 at the lower end of the corresponding screen 24. The discharge pipe 22 at the highest point is connected to a circulation assembly 4. The circulation assembly 4 includes a housing 41 and a transmission shaft 42 that is vertically rotatably inserted into the housing 41. Spiral blades 43 are fixedly sleeved on the outside of the transmission shaft 42. The top of the side wall of the housing 41 near the crushing box 1 is connected to a guide groove 45 that slopes downward and extends to the top of the crushing box 1.

[0040] In this embodiment, as Figure 2As shown, the inside of the crushing chamber 1 is divided into an extrusion chamber 17 and a cutting chamber 18 from top to bottom. Extrusion blocks 171 are fixedly connected to the two inner side walls of the extrusion chamber 17 opposite to the extrusion blades 111. The thickness of the extrusion blocks 171 is equal to the distance between two adjacent extrusion blades 111 on the same extrusion roller 11. The extrusion blocks 171 and the extrusion blades 111 on the same side of the extrusion roller 11 are staggered. The extrusion blades 111 on the two extrusion rollers 11 are staggered, and the extrusion blades 111 on the outer side walls of the two extrusion rollers 11 are staggered and engaged with each other. The extrusion blades 111 cooperate with the extrusion blocks 171, and the extrusion effect is enhanced by another staggered extrusion blade 111. Blades 181 are fixedly connected to the two inner side walls of the cutting chamber 18 opposite to the cutting blades 121. The thickness of the blades 181 is equal to the distance between two adjacent layers of cutting blades 121. They cooperate with the cutting blades 121, and the cutting accuracy is improved by the gap between the cutting blades 121 and the blades 181.

[0041] Furthermore, such as Figure 3 As shown, the two extrusion rollers 11 are connected to the side wall of the crushing box 1 at the same side roller end and are coaxially connected to crushing gears 13. The two crushing gears 13 mesh with each other, so that the two crushing gears 13 can rotate synchronously in opposite directions.

[0042] Furthermore, such as Figure 3 As shown, a crushing motor 14 is fixedly installed on the outside of one side wall of the crushing box 1. The output shaft of the crushing motor 14 is coaxially connected to the cutting roller 12. One of the crushing gears 13 and the output shaft of the crushing motor 14 are coaxially connected to a transmission gear 15. The two transmission gears 15 are connected by a transmission chain 16 to facilitate driving the two crushing gears 13 to rotate and provide power to the extrusion roller 11.

[0043] It is important to note that, such as Figure 1 and Figure 4 As shown, the top surface of the screening box 2 is provided with a feed pipe 21 that communicates with the bottom end of the cutting cavity 18. The feed pipe 21 is located above the higher end of the highest screen 24. The mesh size of several screens 24 decreases from top to bottom, and the plastic is graded and screened to ensure the screening accuracy. Near the bottom of the screening box 2, below the lowest screen 24, there is a slidable chip drawer 25 for collecting waste chips after the plastic is crushed and cut.

[0044] Furthermore, such as Figure 5 As shown, a support column 232 is slidably inserted into the top side wall of the support box 23. A top plate 231, which is fixedly connected to the bottom surface of the screen 24, is fixedly connected to the top of the support column 232. A sliding plate 233, which is slidably engaged in the support box 23, is fixedly connected to the bottom end of the support column 232. The bottom end of the sliding plate 233 and the bottom inner side wall of the support box 23 are elastically connected by a return spring 234 to form an elastic support. This, together with the actuation component 3, increases the vibration amplitude of the screen 24 and improves the screening efficiency.

[0045] In this embodiment, as Figure 4 As shown, the distance between the outer wall of the actuating shaft 31 and the bottom surface of the corresponding screen 24 is less than the width of the actuating plate 32, ensuring that the actuating plate 32 can contact the screen 24 to achieve vibration screening of the screen 24. The number of actuating plates 32 fixedly installed on each actuating shaft 31 is at least two and they are distributed in a ring at equal intervals, so that the actuating plates 32 actuate the screen 24 at a fixed frequency.

[0046] Furthermore, such as Figure 6 As shown, the actuating shafts 31 located at both the top and bottom ends all penetrate the same side wall of the screening box 2 and are coaxially connected to actuating wheels 33. The remaining actuating shafts 31 all penetrate the same side wall of the screening box 2 and are coaxially connected to second double-groove transmission wheels 34. The actuating wheels 33 and adjacent second double-groove transmission wheels 34, as well as two adjacent second double-groove transmission wheels 34, are all connected by actuating transmission belts 35. Adjacent actuating transmission belts 35 do not contact each other. The actuating wheels 33 and second double-groove transmission wheels 34 are connected by actuating transmission belts 35 to achieve synchronous rotation of each actuating shaft 31.

[0047] Furthermore, such as Figure 6 As shown, a toggle motor 36 is fixedly installed on the outer side wall of the screening box 2. The output shaft of the toggle motor 36 is coaxially connected to one of the toggle shafts 31, providing power for the synchronous rotation of each toggle shaft 31.

[0048] It is worth mentioning that, such as Figure 1 and Figure 7 As shown, a transmission motor 44 is fixedly installed on the outer wall of one end of the top and bottom of the housing 41. The output shaft of the transmission motor 44 and the transmission shaft 42 are coaxially connected. The transmission motor 44 drives the transmission shaft 42. The spiral blades 43 transport the plastic coarse material to the guide groove 45. The horizontal height of the top of the housing 41 is greater than the horizontal height of the top of the crushing box 1. The lower end of the guide groove 45 is located directly above the opening of the extrusion chamber 17, completing the coarse material circulation.

[0049] Finally, it should be noted that the crushing motor 14, the actuating motor 36, the transmission motor 44, and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0050] Working Principle: In this embodiment, the high-efficiency crushing and screening device for automotive plastic parts first enters the extrusion chamber 17 of the crushing box 1. It is crushed by the cooperation of two extrusion rollers 11 with staggered extrusion blades 111 and extrusion blocks 171. The crushed plastic falls into the cutting chamber 18, where it is further cut and crushed by the cooperation of the cutting rollers 12 with cutting blades 121 and blades 181. The crushed plastic then enters the screening box 2 through the feed pipe 21. The plastic is sieved on several layers of screens 24 with a letter-shaped distribution and a mesh size decreasing from top to bottom. During the sieving process, the actuating shaft 31 of the actuating component 3 drives the actuating plate 32 to move the screen 24. At the same time, the return spring 234 in the support box 23 works with the support column 232 to make the screen 24 vibrate, which promotes the sieving of plastic. Plastics of different particle sizes are discharged from the discharge pipe 22 at the lower end of the corresponding screen 24. The plastic with the largest particle size is transported to the guide groove 45 through the spiral blade 43 of the circulation component 4 and returned to the top of the crushing box 1 for secondary crushing. The plastic debris generated by crushing falls into the debris collection drawer 25 for collection, realizing efficient crushing and grading of plastic parts.

[0051] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
