Description

Technical Field

[0001] This utility model belongs to the technical field of glass breaking devices, specifically relating to a broken and recycled rear windshield device for automobiles. Background Technology

[0002] With the continuous increase in car ownership, the number of scrapped cars is also increasing, and the recycling and reuse of scrapped cars has become a consensus. Among them, car glass is divided into front windshield and rear windshield. The front windshield is made of two layers of glass with a tough PVB (polyvinyl butyral) film sandwiched in between, while the rear windshield is usually tempered glass. Because the front windshield and rear windshield have different designs, they need to be processed separately during recycling.

[0003] For the rear windshield, in order to facilitate transportation, it needs to be broken into small particles. Currently, glass breaking devices mainly rely on physical impact to break the glass, resulting in a large variation in the size of the broken glass particles. Utility Model Content

[0004] Based on the problems mentioned in the background art above, this utility model provides a vehicle rear windshield breakage and recycling device to solve the problem of large differences in the size of glass particles broken by current glass breaking devices.

[0005] The technical solution adopted in this utility model is as follows:

[0023] like Figures 1-2 As shown, a vehicle rear windshield breakage and recycling device includes:

[0024] The box body 101 has a support frame 102 at the bottom, which supports the entire device. The box body 101 also has a discharge port 103 at the bottom, which facilitates the discharge of glass particles.

[0025] The inclined feeding component includes a feeding hopper 201, which is inclinedly arranged on one side of the top of the box 101. The lower end of the feeding hopper 201 is located inside the box 101 and is provided with a hook 204. Multiple through slots 203 are provided at intervals on the lower end of the feeding hopper 201. The higher end of the feeding hopper 201 is located outside the box 101 and is provided with a baffle 202. In use, the worker feeds the rear windshield along the higher end of the feeding hopper 201, causing the rear windshield to slide along the inclined wall of the feeding hopper 201, so that the rear windshield slides to the lower end of the feeding hopper 201 and one side of it abuts against the hook 204, so that the rear windshield is kept on the top of the through slots 203 of the feeding hopper 201.

[0026] A crushing component is installed inside the housing 101 at the lower end of the inclined feed component. The crushing component includes an assembly shaft 301, which rotatably rotates inside the housing 101. A stepper motor 302 is mounted on the outer wall of the housing 101 via a mounting base 303. The drive shaft of the stepper motor 302 is connected to one end of the assembly shaft 301. The stepper motor 302 is a 1.8° stepper motor, model NEMA 17. (42BYGH-401A) The assembly shaft 301 is equipped with a striking wheel 304, and ten rows of striking rods 305 are arranged in an array on the striking wheel 304. A through groove 306 is provided between each striking rod 305 in each row. Each striking rod 305 has a pointed tip 307 at its end. Each striking rod 305 corresponds to the position of the corresponding through groove 203. Each branch rod at the bottom of the feeding hopper 201 corresponds to the position of the corresponding through groove 206. By arranging ten rows of striking rods 305 in an array on the striking wheel 304, when the 1.8° stepper motor drives the striking wheel 304 to rotate intermittently at a rotation angle of 36°, each row of striking rods 305 can rotate to the through groove 203 of the feeding hopper 201 and can pass down through the through groove 203.

[0027] The stepper motor 302's drive shaft rotates intermittently at a 36° rotation angle. The controller (STM32 microcontroller) sends a series of 20 pulse signals to the stepper motor 302's driver (Leica DM556 driver). Upon receiving each pulse, the driver energizes the motor windings in a pre-defined sequence, causing the motor rotor to rotate precisely 1.8°. Twenty consecutive pulses drive the rotor to rotate a cumulative 36°. After sending all 20 pulses, the controller stops sending new pulses. At this point, the driver maintains its maximum rotation angle. In the next step, when the winding is energized, due to the characteristics of the stepper motor 302, even when it is stopped, as long as the winding is energized, the stepper motor 302 can generate holding torque (self-locking force) to firmly lock the rotor at the current position (i.e., at an integer multiple of 36°), resisting certain external disturbances and preventing it from rotating freely. When the controller sends the next signal to the driver, after the driver receives the next start signal, it drives the rotor of the stepper motor 302 to rotate 36°, thus ultimately achieving intermittent rotary motion with a rotation angle of 36°.

[0028] When the rear windshield is placed on top of the through slot 203 of the feeding hopper 201, the stepper motor 302 drives the striking wheel 304 to perform intermittent reverse rotation at a rotation angle of 36°. As each striking rod 305 in the corresponding row on the striking wheel 304 passes down through the through slot 203, the pointed tip 307 at the end of each striking rod 305 in the row can strike the edge of the rear windshield placed on top of the through slot 203 of the feeding hopper 201, thereby causing the rear windshield on top of the through slot 203 to be broken, thus performing the initial breakage of the rear windshield.

[0029] An inclined guide plate 401 is provided on the inner inclined wall of the box body 101, and an inclined guide plate 402 is provided on the inner wall of the box body 101 above the extrusion cylinder 504. When the rear windshield is initially broken by the impact, the fragments of the initially broken rear windshield can fall onto the inclined guide plate 401, and then be guided onto the inclined guide plate 402, and finally be guided along the inclined guide plate 402 to fall into the inlet of the crushing component.

[0030] The crushing component is arranged above the discharge port 103. The crushing component includes a mounting shaft 501, which is rotatably arranged above the discharge port 103. A motor 502 is arranged on the outer wall of the housing 101 through the assembly base 503. The drive shaft of the motor 502 is connected to one end of the mounting shaft 501. An extrusion cylinder 504 is arranged on the mounting shaft 501. Multiple inclined convex rollers 505 are arranged in an array on the peripheral side wall of the extrusion cylinder 504. An extrusion seat 506 is arranged on one side of the discharge port 103. Multiple convex rollers 507 are arranged in an array on the arc-shaped wall of the extrusion seat 506.

[0031] When the initially broken rear windshield fragments are guided along the inclined guide plate 402 and fall into the upper part between the extrusion seat 506 and the extrusion cylinder 504, the extrusion cylinder 504 is driven to rotate in the reverse direction by the motor 502. During the reverse rotation of the extrusion cylinder 504, the inclined convex roller 505 on the extrusion cylinder 504 can push the glass fragments into the gap area between the extrusion cylinder 504 and the extrusion seat 506. During the process of the glass fragments being fed into the gap area between the extrusion cylinder 504 and the extrusion seat 506, the glass fragments entering the gap area can be further crushed and refined under the extrusion action of the inclined convex roller 505 and the convex roller 507, so that the rear windshield fragments are crushed into particles of similar size and finally discharged from the discharge port 103.

[0032] The present invention has been described in detail above. The specific embodiments are provided only to help understand the method and core idea of ​​the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
