Description

Technical Field

[0001] This utility model relates to the field of electric vehicle instrument manufacturing technology, and in particular to a waste shell crushing device for electric vehicle instrument manufacturing. Background Technology

[0002] With the booming development of the electric vehicle industry, electric vehicle instrument panels, as an important component of vehicles, are being produced on an ever-expanding scale. During the production process, a large number of waste shells are generated. If these waste shells are not properly disposed of, they will not only occupy a lot of space but also cause environmental pollution. Crushing these waste shells to achieve resource recycling and reuse has become an urgent problem for electric vehicle instrument panel manufacturers. This has prompted the research and development and application of waste shell crushing devices for electric vehicle instrument panel production.

[0003] Currently, some existing electric vehicle instrument panel waste shell crushing devices on the market have significant shortcomings in the screening process. Some devices use fixed screen plates for screening, during which debris easily accumulates and clogs the screen holes. As the screening time increases, the clogging of the screen holes becomes more and more serious, resulting in a significant decrease in screening efficiency. This is because the debris generated during the crushing process varies in size and shape, and some smaller debris is easily stuck in the screen holes. Furthermore, there is a lack of an effective cleaning mechanism. When the screen holes are clogged, qualified debris cannot pass through the screen plate smoothly, requiring frequent manual cleaning of the screen plate. This not only increases labor costs but also requires frequent machine shutdowns, leading to reduced production efficiency and affecting the economic benefits of enterprises. In response to this technical problem, this application proposes a waste shell crushing device for electric vehicle instrument production. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waste casing crushing device for electric vehicle instrument production. The device uses a motor to drive an eccentric wheel to rotate, which, in conjunction with a spring, causes the screen plate to shake. During the screening process, the shaking of the screen plate can promptly shake off the debris stuck in the screen holes. When the handle is released, the torsion spring will drive the baffle to quickly return to its original position, closing the opening at the top of the device casing. During the crushing process, the baffle can effectively block debris that may be splashed out during crushing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A waste casing crushing device for electric vehicle instrument production includes a device housing. A fixed shaft is rotatably connected to the top side of the inner wall of the device housing. A baffle is fixedly connected to the outer wall of the fixed shaft. A handle is fixedly connected to the top of the baffle. A fixing plate is connected to the outer wall of the fixed shaft via a torsion spring. A noise reduction assembly is provided on the inner wall of the device housing. A crushing roller one is rotatably connected to the inner wall of the device housing. A crushing roller two is connected to the outer wall of the crushing roller one via a linkage assembly. A screen plate is slidably connected to the inner wall of the device housing. A support frame is fixedly connected to the front end of the device housing. A motor two is mounted on the top of the support frame via a fixed frame. An eccentric wheel is fixedly connected to the drive end of the motor two. The inner wall of the support frame is connected to the screen plate via the eccentric wheel, and the rear end of the support frame is connected to the screen plate via a spring.

[0007] Furthermore, the linkage assembly includes a timing belt located on the outer wall of the first crushing roller. The first crushing roller is connected to the first gear via the timing belt. The right end of the first gear is meshed with a second gear, which is fixedly connected to the outer wall of the second crushing roller.

[0008] Furthermore, a motor is mounted on the front end of the device housing via a fixing frame, and the drive end of the motor is connected to the crushing roller.

[0009] Furthermore, the noise reduction assembly includes a fixing plate located on the inner wall of the device housing, a rubber pad fixedly connected to the top of the fixing plate, and the rubber pad being disposed at the bottom of the baffle.

[0010] Furthermore, one end of the torsion spring is connected to the front end of the device housing, and the other end of the device housing is connected to the rear end of the fixing plate.

[0011] Furthermore, one end of the spring is connected to the rear end of the support frame, and the other end of the spring is connected to the front end of the sieve plate.

[0012] Furthermore, a guide plate is fixedly connected to the inner wall of the device housing.

[0013] Furthermore, the inner wall of the device housing is fixedly connected with a ramp.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the device drives the eccentric wheel to rotate through the second motor, which, together with the spring, causes the screen plate to shake. During the screening process, the shaking of the screen plate can promptly shake off the debris stuck in the screen holes, preventing debris from accumulating and clogging the screen holes, ensuring the continuous and efficient screening operation, eliminating the need for frequent machine stops to clean the screen plate, and improving production efficiency.

[0016] 2. In this utility model, after the waste shell is put in, the handle is released and the torsion spring will drive the baffle to return to its position quickly, closing the opening at the top of the device shell. During the crushing process, the baffle can effectively block the debris that may be splashed out during crushing, preventing the debris from flying out of the device and causing injury to the operator, thus ensuring the personal safety of the operator.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3An embodiment of this utility model provides a waste shell crushing device for electric vehicle instrument production, including a device shell 1, a fixed shaft 13 rotatably connected to the top side of the inner wall of the device shell 1, a baffle 14 fixedly connected to the outer wall of the fixed shaft 13, a handle 17 fixedly connected to the top of the baffle 14, a fixed plate 16 connected to the outer wall of the fixed shaft 13 by a torsion spring 15, a fixed plate 19 and a rubber pad 20 provided on the inner wall of the device shell 1, a crushing roller 2 rotatably connected to the inner wall of the device shell 1, a crushing roller 6 connected to the outer wall of the crushing roller 2 by a synchronous belt 3, a gear 4 and a gear 5, a screen plate 11 slidably connected to the inner wall of the device shell 1, a support frame 8 fixedly connected to the front end of the device shell 1, a motor 9 mounted on the top of the support frame 8 by a fixed frame, an eccentric wheel 10 fixedly connected to the drive end of the motor 9, the inner wall of the support frame 8 connected to the screen plate 11 by the eccentric wheel 10, and the rear end of the support frame 8 connected to the screen plate 11 by a spring 21;

[0026] Specifically, the operator holds handle 17 and rotates baffle 14 around fixed shaft 13. After baffle 14 rotates and opens, the operator puts the discarded electric vehicle instrument casing to be crushed into the top opening of device housing 1. After the disposal is completed, the operator releases handle 17. At this time, torsion spring 15 comes into play. One end of torsion spring 15 is connected to the front end of device housing 1, and the other end is connected to the rear end of fixed plate 16. Under the torsion of torsion spring 15, baffle 14 will rotate around fixed shaft 13 and return to its initial position, closing device housing 1. The top opening effectively blocks debris that may fly out during crushing, preventing it from injuring operators and ensuring their safety. An eccentric wheel 10 is installed at the drive end of motor 29. Motor 29 drives the eccentric wheel 10 to rotate. During rotation, the eccentric structure of the eccentric wheel 10 continuously changes the force exerted on the screen plate 11. Simultaneously, the spring 21 connected to the rear end of the support frame 8 is connected to the front end of the screen plate 11. Under the combined action of the eccentric wheel 10 and the spring 21, the screen plate 11 vibrates. This vibration effectively prevents debris from clogging the screen holes and shakes off any unqualified debris remaining on the screen plate 11, allowing it to exit from the left outlet of the device housing 1 for subsequent secondary crushing.

[0027] Reference Figure 2 , Figure 4 and Figure 5The synchronous belt 3 is located on the outer wall of the crushing roller 2. The crushing roller 2 is connected to the gear 4 through the synchronous belt 3. The right end of the gear 4 is meshed with the gear 5. The gear 5 is fixedly connected to the outer wall of the crushing roller 6. The front end of the device housing 1 is equipped with the motor 7 through the fixing frame. The drive end of the motor 7 is connected to the crushing roller 2. The fixing plate 19 is located on the inner wall of the device housing 1. The top end of the fixing plate 19 is fixedly connected to the rubber pad 20. The rubber pad 20 is set at the bottom end of the baffle 14. One end of the torsion spring 15 is connected to the front end of the device housing 1, and the other end of the device housing 1 is connected to the rear end of the fixing plate 16. One end of the spring 21 is connected to the rear end of the support frame 8, and the other end of the spring 21 is connected to the front end of the screen plate 11. The inner wall of the device housing 1 is fixedly connected to the guide plate 18 and the inner wall of the device housing 1 is fixedly connected to the ramp 12.

[0028] Specifically, the drive shaft of motor 7 is closely connected to crushing roller 2. After motor 7 is powered on, the power generated is transmitted to crushing roller 2 through the drive shaft, causing it to rotate. The outer wall of crushing roller 2 is surrounded by synchronous belt 3. When crushing roller 2 rotates, synchronous belt 3 moves synchronously. The other end of synchronous belt 3 is connected to gear 4. Driven by synchronous belt 3, gear 4 also begins to rotate synchronously. Since gear 4 and gear 5 are meshed, when gear 4 rotates, its teeth push gear 5 to rotate. Gear 5 is firmly fixed to the outer wall of crushing roller 6, so the rotation of gear 5 will drive crushing roller 6 to rotate together. Due to the characteristics of gear transmission, the rotation direction of crushing roller 6 is opposite to that of crushing roller 2, thus enabling the crushing of waste shells. The waste shells fed into the device slide down along guide plate 18 under the guidance of guide plate 18 and finally fall accurately. At the center position of crushing roller 12 and crushing roller 26, the crushed debris falls downward onto screen plate 11. Screen plate 11 has screen holes of a specific size. Qualified debris that meets the size requirements can pass through the screen holes and fall onto the slope 12 below. The inclined design of slope 12 allows qualified debris to slide down along slope 12 and finally be discharged from the right outlet of the device shell 1. Unqualified debris that is too large and does not meet the requirements will remain on screen plate 11. Fixing plate 19 is fixed to the inner wall of device shell 1. It plays a limiting role for baffle 14, ensuring that baffle 14 remains parallel to guide plate 18 after returning to its position, making the feeding and crushing process of waste shell more stable. At the same time, the rubber pad 20 fixed at the top of fixing plate 19 is located below the bottom of baffle 14. When baffle 14 returns to its position and contacts fixing plate 19, rubber pad 20 can effectively reduce the noise generated when the two collide, reducing the noise of the equipment during operation.

[0029] Working principle: First, start motor 7 to drive crushing roller 2 to rotate. Under the action of synchronous belt 3, it drives gear 4 to rotate synchronously. Then, because gear 4 and gear 5 are meshed, gear 5 drives crushing roller 6 to rotate in the opposite direction to crushing roller 2. Then, turn baffle 14 by handle 17 to put the waste shell to be crushed into the outer shell 1 of the device. Then, release handle 17. Under the action of torsion spring 15, baffle 14 will return to its original position. The put-in waste shell will fall into the crusher under the guidance of guide plate 18. At the center of crushing roller 1 2 and crushing roller 2 6, the waste shell is crushed. After the waste shell is crushed, it falls onto screen plate 11 for screening. Qualified fragments will pass through screen plate 11 and fall onto slope 12, and be discharged from the right outlet. Qualified fragments will remain on screen plate 11. At this time, motor 2 9 is started, which drives eccentric wheel 10 to rotate, thereby causing screen plate 11 to shake, thus preventing fragments from clogging screen plate 11, and shaking unqualified fragments to the left outlet for discharge, which is convenient for secondary crushing of unqualified fragments.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
