[0024] Example
[0025] This utility model provides a waste recycling device for the production of sealing rings, see reference. Figs. 1-2 As shown, the device includes a crushing and screening box 1. A feed hopper 2, connected to the inner cavity of the crushing and screening box 1, is located on one side of the top end face of the box. Two opposing first crushing rollers 3 are rotatably arranged inside the crushing and screening box 1 and located below the feed hopper 2. A first guide plate 6 is located below the first crushing rollers 3. Two opposing second crushing rollers 14 are rotatably arranged inside the crushing and screening box 1 on one side of the bottom of the first guide plate 6. The arrangement of the second crushing rollers 14 improves the crushing effect on the sealing ring waste. A second guide plate 15 is located at the bottom of the second crushing rollers 14. A striking mechanism is provided above both the second guide plate 15 and the first guide plate 6. A conveying box 4 is located on one side of the crushing and screening box 1, located near the feed hopper 2. A discharge chute 13 is provided between the conveying box 4 and the crushing and screening box 1, allowing the crushing and screening box 1 and the conveying box 4 to communicate.
[0026] One end of the first guide plate 6 is fixed to the inner wall of the crushing and screening box 1, and the other end of the first guide plate 6 extends downward at an angle to the top of the two second crushing rollers 14. The inclined setting of the first guide plate 6 facilitates the precise conveying of the waste material after being crushed by the first crushing roller 3 to the two second crushing rollers 14 for secondary crushing.
[0027] One end of the second guide plate 15 is fixed to the inner wall of the crushing and screening box 1, and the other end of the second guide plate 15 extends downward to the discharge chute 13. The inclined setting of the second guide plate 15 facilitates the conveying of waste materials that do not meet the discharge requirements to the conveying box 4.
[0028] Both the first guide plate 6 and the second guide plate 15 are provided with multiple filter holes 16, which can be used to screen the waste material after crushing.
[0029] The impact mechanism includes a drive motor 7 mounted on the outer wall of the crushing and screening box 1. The output end of the drive motor 7 extends into the inner cavity of the crushing and screening box 1 and is rotatably connected to a connecting shaft 8. The connecting shaft 8 is provided with an impact plate 10 that contacts the first guide plate 6 or the second guide plate 15. The impact plate 10 is made of rubber to avoid damage to the first guide plate 6 or the second guide plate 15.
[0030] In use, the drive motor 7 drives the connecting shaft 8 to rotate the striking plate 10, thereby striking the first guide plate 6 or the second guide plate 15 to make the first guide plate 6 or the second guide plate 15 vibrate, so as to prevent large particles of waste from clogging the filter holes 16 and affecting the screening of small particles of waste.
[0031] The conveying box 4 is equipped with a conveying motor 5 on its top end face. The output end of the conveying motor 5 extends to the inside of the conveying box 4 and is equipped with a rotating shaft 11. The rotating shaft 11 is equipped with a spiral conveying blade 12. Through the arrangement of the spiral conveying blade 12 and the rotating shaft 11, waste materials that do not meet the discharge requirements can be conveyed to the crushing and screening box 1. The top side of the conveying box 4 is equipped with a conveying pipe 9 located above the feed hopper 2. Through the arrangement of the conveying pipe 9, waste materials that do not meet the discharge requirements can be conveyed to the feed hopper 2.
[0032] The working principle of this utility model is as follows:
[0033] In operation, the waste sealing rings are first fed into the feed hopper 2. The waste then falls between the two first crushing rollers 3. The two first crushing rollers 3 rotate to crush the waste, breaking it into granular waste. The granular waste, after being crushed by the first crushing rollers 3, falls onto the first guide plate 6. The drive motor 7 is started, driving the connecting shaft 8 to rotate the striking plate 10, which then strikes the first guide plate 6, causing it to vibrate. This prevents large particles of waste from clogging the filter holes 16 on the first guide plate 6, affecting the screening of small particles. Fine particles of waste fall through the filter holes 16 on the first guide plate 6 and the second guide plate 15 to the bottom of the crushing and screening box 1. Simultaneously, large particles of waste slide down the inclined angle of the first guide plate 6 between the two second crushing rollers 14 for secondary crushing. The large particles of waste... The material falls onto the second guide plate 15 after secondary crushing. The drive motor 7 is started, which drives the connecting shaft 8 to rotate the striking plate 10, thereby striking the second guide plate 15 to generate vibration. This prevents large particles of waste from clogging the filter holes 16 on the second guide plate 15 and affecting the screening of small particles. Fine particles of waste fall through the filter holes 16 on the second guide plate 15 to the bottom of the crushing and screening box 1. At the same time, waste that does not meet the discharge standard is conveyed along the second guide plate 15 to the conveying box 4. The spiral conveying blades 12 convey the waste that does not meet the discharge standard back to the feed hopper 2 for repeated crushing. This utility model can perform multiple crushing processes on the sealing ring waste, ensuring that the size of the crushed sealing ring waste meets the discharge standard, greatly improving the recycling efficiency of sealing ring waste and reducing its applicability.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0035] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
