[0041] As one technical optimization scheme of the present application, an opening is formed in one side outer wall of the primary crushing box 3, and a sealing plate 10 is rotatably installed inside the opening. A third driving device is pre-provided on the one side outer wall of the primary crushing box 3, and an output end of the third driving device is connected with a rotating part at one end of the sealing plate 10, so as to drive the sealing plate 10 to rotate and adjust inside the opening.

After the rotating frame 6 is counterclockwise downward rotated by a certain angle, the right end of the rotating frame 6 abuts against the top end of the guide plate 16, so that the impurities falling on the bottom surface of the rotating frame 6 can slide to the top of the guide plate 16, and then be guided by the guide plate 16 to be discharged outward through the discharge outlets 8 and temporarily stored in the inside of the collecting box 7, so as to achieve the effect of automatically cleaning and removing the filtered impurities.

[0043] As one technical optimization scheme of the present application, two third sliding grooves 11 are formed in the one side outer wall of the fixed frame 2, and a third sliding block 13 is installed in each of the third sliding grooves 11. The two third sliding blocks 13 are jointly installed with a moving plate 5 at the end away from the third sliding grooves 11, and the second crushing box 4 is placed on the top of the moving plate 5. A third linear motor is pre-provided in each of the third sliding grooves 11, and the two third linear motors can drive the two third sliding blocks 13 to move up and down in the corresponding third sliding grooves 11, so as to drive the moving plate 5 and the second crushing box 4 placed on the top of the moving plate 5 to move up and down below the primary crushing box 3.

[0044] In the embodiment, the cable material object to be crushed is a polyvinyl chloride cable skin which is processed to have the same length in advance, so as to avoid that the length of the cable material is too long or too short, and the crushing quality cannot meet the expectation.

[0045] In the present application, when a user uses the device, if the user wants to use the device to crush the cable material object, the user can Figure 1 、 Figure 4 and Figure 7As shown, the cable material to be crushed is placed on the top of the rotating frame 6 and on the top of the two filter plates 14. First, the two second sliders 23 are controlled to move back and forth in the corresponding second sliding grooves 22, thereby driving the two filter plates 14 to move back and forth inside the rotating frame 6 for adjustment, so that the cable material placed on the top of the two filter plates 14 is synchronously subjected to small amplitude shaking. Since the cable material has the same length and large volume, it cannot fall downward from the inside of the rotating frame 6 during the small amplitude shaking, but the impurities such as stones mixed inside can fall upward from the filter grooves inside the two filter plates 14 to the inner bottom surface of the rotating frame 6 for temporary storage, thereby achieving the effect of pre-filtering and removing the impurities such as stones inside the cable material to be crushed, and avoiding the problem of such impurities entering the inside of the primary crushing box 3 together to damage the crushing mechanism.

[0046] After the impurities such as stones mixed inside the cable material are filtered and removed, the two filter plates 14 are controlled to rotate upward together, as shown in Figure 4 which drives the two filter plates 14 to move the cable material temporarily stored on the top thereof toward the center position and simultaneously clamps and fixes the cable material. Then, the two third sliders 13 are controlled to move upward in the corresponding third sliding grooves 11, thereby driving the moving plate 5 and the secondary crushing box 4 to move upward together. When the distance between the top end of the secondary crushing box 4 and the primary crushing box 3 is adjusted to the minimum state, the second driving motor 21 is controlled to drive the rotating frame 6 to slowly rotate clockwise downward on the top of the primary crushing box 3 to the state of abutting against the top of the guide plate 16, so that the impurities such as stones temporarily stored on the inner bottom surface of the rotating frame 6 slide down to the top of the guide plate 16 and are discharged outward through the discharge port 8 to the inside of the collection box 7 for automatic collection, thereby achieving the effect of automatically cleaning and removing the filtered impurities.

[0047] After the impurities such as stones on the inner bottom surface of the rotating frame 6 are discharged outward, the rotating frame 6 can continue to rotate clockwise, thereby driving the two filter plates 14 originally located on the top of the rotating frame 6 to rotate completely into the inside of the primary crushing box 3. At this time, the two filter plates 14 are controlled to rotate away from each other to reset, so that the clamped and fixed cable material can be discharged to the center position inside the primary crushing box 3, thereby facilitating the rapid crushing of the cable material by the two crushing rollers 15. The rotating frame 6 located on the top of the primary crushing box 3 can conveniently seal the top opening of the primary crushing box 3, thereby avoiding the cable material being crushed from spattering out of the top opening of the primary crushing box 3.

[0048] After the cable material is subjected to primary crushing by the two crushing rollers 15, the cable material can be discharged downward from the bottom of the primary crushing box 3 to the inside of the secondary crushing box 4, so as to be subjected to more refined crushing by the related crushing equipment arranged inside the secondary crushing box 4, thereby facilitating the subsequent reprocessing and production of the cable material.

[0049] After the two crushing rollers 15 continuously crush the cable material for a period of time, the internal temperature of the two crushing rollers 15 rises. In order to avoid the temperature of the two crushing rollers 15 being too high, causing the cable material to melt and adhere to the surface of the crushing roller 15 during the crushing process of the cable material, the two crushing rollers 15 can be stopped after the crushing of the cable material in the first crushing box 3 is completed. Then, the two filter plates 14 are controlled to rotate upward together to an inclined state inside the rotating frame 6, and the rotating frame 6 itself is controlled to rotate 90 degrees clockwise downward at the top of the first crushing box 3, so that it is in a vertical state at this time, and the blowing head 27 arranged at one end of one of the filter plates 14 is rotated to the inside of the first crushing box 3. The two corresponding protection plates 25 are controlled to rotate away from each other to open, thereby unblocking the multiple air outlets 28. After the external pre-set blowing equipment is started, the multiple air outlets 28 can blow air towards the two crushing rollers 15 for air cooling and heat dissipation treatment. With the back and forth movement of the two first sliding blocks 12 in the corresponding first sliding grooves 9, the multiple air outlets 28 can more comprehensively cool and heat the two crushing rollers 15, improve the heat dissipation efficiency of the two crushing rollers 15, and quickly reduce the temperature of the two crushing rollers 15. The two crushing rollers 15 can continue to be used in the subsequent crushing process of the cable material. Moreover, during the cooling and heat dissipation process of the multiple air outlets 28 on the two crushing rollers 15, the multiple air outlets 28 can also move and adjust inside the first crushing box 3 by the extension and retraction of the two first electric telescopic rods 19, so that the multiple air outlets 28 can also blow and discharge the cable material adhering to the inner wall of the first crushing box 3 downward to the inside of the second crushing box 4 below, indirectly having the effect of automatically cleaning the first crushing box 3.

[0050] When the cable material enters the inside of the first crushing box 3 and is crushed by the two crushing rollers 15, the crushing rollers 15 are worn out after a long time of use, or the cable material is mixed with other hard materials, so that the cable material is blocked between the two crushing rollers 15. In order to avoid the situation from getting worse and to quickly handle the blocking situation, the sealing plate 10 can be controlled to rotate downward to open, and then the rotating frame 6 is controlled to rotate counterclockwise downward by 90 degrees, driving the cleaning brush 29 at one end of the other filter plate 14 to rotate to the inside of the first crushing box 3 and above the two crushing rollers 15. After the two corresponding protection plates 25 are controlled to rotate away from each other, the corresponding two second electric telescopic rods 26 are controlled to extend at the same time, driving the cleaning brush 29 to move downward to the blocked position. By moving the two first sliding blocks 12 in the corresponding first sliding grooves 9 toward the sealing plate 10, the cleaning brush 29 can automatically push the blocked cable material outward for cleaning, which facilitates quick processing of the cable material blocking situation. Moreover, by cooperating with other components, the cleaning brush 29 can also avoid manual cleaning, improve safety during processing of the cable material blocking situation, and further improve the overall applicability of the device.

[0051] At the same time, after the two crushing rollers 15 are used for a period of time, some cable material will inevitably adhere to the surface of the two crushing rollers 15. The above-mentioned steps for processing the cable material blocking in the first crushing box 3 can be repeated, so that the cleaning brush 29 moves in the first crushing box 3, and cooperates with the slow rotation of the two crushing rollers 15 to automatically brush and clean the cable material adhering to the surface of the two crushing rollers 15, thereby improving the applicability of the cleaning brush 29. After the cleaning brush 29 cleans the cable material on the surface of the two crushing rollers 15, the rotating frame 6 can be controlled to rotate to drive the air blowing head 27 to rotate to the inside of the first crushing box 3 to blow and clean the cleaned cable material, thereby improving the efficiency of cleaning the cleaned cable material and facilitating the subsequent crushing work of the two crushing rollers 15 on the cable material.

[0052] If the two crushing rollers 15 in the first crushing box 3 need to be disassembled and repaired, in order to facilitate the removal of the disassembled crushing rollers 15 from the inside of the first crushing box 3, the extension ends of the two first electric telescopic rods 19 can be controlled to extend upward at the same time to push the rotating frame 6 and other components to move upward to a suitable height on the top of the first crushing box 3. Then, the two rotating blocks 18 drive the first electric telescopic rods 19 and the rotating frame 6 and other components to rotate counterclockwise downward by 90 degrees, driving the rotating frame 6 and other components to rotate to the right side of the first crushing box 3, so that the workers can conveniently disassemble the two crushing rollers 15 from the top opening of the first crushing box 3, avoiding the disassembly of the two crushing rollers 15 being hindered by the rotating frame 6 and other components.

[0053] After the control rotating frame 6 and other components are rotated to the right side of the primary crushing box 3, the secondary crushing box 4 can be removed from the top of the moving plate 5, and then... Figure 10 As shown, the two rotating blocks 18 are controlled to continue rotating downwards, causing the rotating frame 6 and other components to rotate to the bottom of the primary crushing chamber 3. Then, the telescopic ends of the two first electric telescopic rods 19 are controlled to continue extending downwards, providing space for the rotation adjustment of the rotating frame 6. Next, the rotating frame 6 is controlled to rotate 180 degrees between the two housings 20, causing the two filter plates 14 and other components to rotate to near the bottom of the primary crushing chamber 3. Then, the two filter plates 14 are controlled to rotate upwards together into an inclined state, so that the two protective plates 25 at the top of the two filter plates 14 are located at the bottom of the two crushing rollers 15. As the telescopic ends of the two first electric telescopic rods 19 retract, The protective plates 25 at the top of the two filter plates 14 abut against the crushing rollers 15, and the extension ends of the two first electric telescopic rods 19 are controlled to retract. With the help of the protective plates 25 and other components that abut against the two crushing rollers 15, the two crushing rollers 15 are pushed upward inside the first-stage crushing box 3 until they move to a suitable height. Then, the sealing plate 10 is controlled to rotate downward and open, so that the staff can take out the two crushing rollers 15 from the other side of the first-stage crushing box 3. This facilitates the removal and maintenance of the two crushing rollers 15 and further improves the applicability of the drive mechanism, rotating frame 6 and two filter plates 14.

[0054] After the device is used, the secondary crushing box 4 will be removed from the top of the moving plate 5. At this time, the two third sliders 13 can be controlled to move upward inside the corresponding third slide groove 11, which will drive the moving plate 5 to seal the bottom opening of the primary crushing box 3. Meanwhile, the rotating frame 6 can seal the top opening of the primary crushing box 3, ensuring that the relevant components inside the primary crushing box 3 will not be adversely affected by other external factors when not in use, thus improving the protection effect of the primary crushing box 3 when not in use.
