Description

Technical Field

[0001] The present invention relates to the technical field of polyvinyl chloride cable material recycling, and specifically relates to a crushing device for the reuse of polyvinyl chloride cable materials. Background Art

[0002] Polyvinyl chloride cable material is a plastic material with polyvinyl chloride resin as the main body, and is mixed with various additives such as stabilizers, plasticizers, lubricants and fillers. It is mainly used for the insulation and protection layers of wires and cables. A large amount of waste will be generated during the use of polyvinyl chloride cable materials. By recycling and reusing the polyvinyl chloride cable materials from waste wires and cables, the landfill and incineration of plastic waste can be effectively reduced, thus reducing the pressure on the environment; and the recycled polyvinyl chloride cable materials can be reprocessed into new products, such as wires and cables, plastic pipes, etc. This not only reduces the demand for raw materials, but also creates economic value.

[0003] In the prior art for the recycling and reusing of polyvinyl chloride cable materials, most of them rely on relevant crushing devices to crush and process the recycled cable materials. After crushing them into a smaller volume state, it is convenient for subsequent melting and pelletizing processing; during the crushing process of the cable materials, due to the relatively complex working environment around the crushing device, some stones and other impurities will be doped inside the cable materials. If the cable materials are directly put into the crushing device for crushing treatment, these stones and other impurities will damage the crushing mechanism inside the crushing device, thereby reducing the service life of the crushing device and being unfavorable for the long-term use of the crushing device, making the crushing device unable to meet people's usage requirements. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a crushing device for the reuse of polyvinyl chloride cable materials.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions: A crushing device for the reuse of polyvinyl chloride cable materials, including a base and a primary crushing box. A fixing frame is installed on the top of the base, the primary crushing box is installed on the top of the fixing frame, a crushing mechanism is arranged inside the primary crushing box, a rotating frame is arranged on the top of the primary crushing box, driving mechanisms for driving the rotation and movement of the rotating frame are arranged on the outer walls of both sides of the primary crushing box, and a filtering mechanism for pre-removing stone impurities in the cable materials is arranged inside the rotating frame. The filtering mechanism includes two filter plates arranged inside the rotating frame, and there are gaps between both filter plates and the inner bottom surface of the rotating frame.

[0006] Optionally, the crushing mechanism includes two crushing rollers, both of which are rotatably installed inside the primary crushing box through rotating shafts provided at both ends. On one outer wall of the primary crushing box, two first driving motors are preset, and the output ends of the two first driving motors are respectively connected to the corresponding rotating shafts.

[0007] Optionally, the driving mechanism includes first sliding grooves opened on the outer walls on both sides of the primary crushing box. Inside both first sliding grooves, first sliders are installed. At one end of both first sliders away from the first sliding grooves, moving blocks are installed. At one end of both moving blocks away from the first sliders, rotating blocks are rotatably installed.

[0008] Optionally, at the top of both rotating blocks, a housing is connected through a first electric telescopic rod. A rotating frame is rotatably installed between the two housings. Inside one of the housings, a second driving motor is installed, and the output end of the second driving motor is connected to the rotating frame.

[0009] Optionally, second sliding grooves are opened on both inner walls of the rotating frame. Inside both second sliding grooves, second sliders are installed. At one end of both filter plates close to each other, they are rotatably connected to the two second sliders.

[0010] Optionally, two second electric telescopic rods are installed inside both filter plates. The telescopic ends of the two second electric telescopic rods are jointly installed with a mounting plate. On the outer walls on both sides of the two mounting plates away from each other, a cleaning brush and a blowing head are respectively installed.

[0011] Optionally, a plurality of air outlets are opened inside the blowing head. On the outer walls on both sides of the two mounting plates away from each other, two protection plates for shielding and protecting the cleaning brush and the air outlets are rotatably installed.

[0012] Optionally, an opening is opened on one outer wall of the primary crushing box, and a sealing plate is rotatably installed inside the opening.

[0013] Optionally, a plurality of discharge ports for discharging stone impurities are opened on the other outer wall of the primary crushing box. A guiding plate is installed on the inner wall of the primary crushing box close to the discharge port. A collection box is slidably installed on the outer wall of the primary crushing box close to the discharge port.

[0014] Optionally, two third sliding grooves are opened on one outer wall of the fixed frame. Inside both third sliding grooves, third sliders are installed. At one end of both third sliders away from the third sliding grooves, they are jointly installed with a moving plate, and a secondary crushing box is placed on the top of the moving plate.

[0015] The beneficial effects of the present invention are: 1. In this invention, before crushing the cable material, the cable material can be placed on top of two filter plates and gently shaken to pre-filter and remove impurities such as stones doped inside the cable material, preventing such impurities from entering the inside of the primary crushing box together, damaging the crushing mechanism, and reducing the service life of the primary crushing box. This is beneficial for the long-term use of the primary crushing box.

[0016] 2. In this invention, after filtering and removing impurities such as stones doped inside the cable material, control the second drive motor to drive the rotating frame to slowly rotate clockwise downward on top of the primary crushing box until it abuts against the top of the guiding plate, so that the stones and other impurities temporarily stored on the inner bottom surface of the rotating frame slide down onto the top of the guiding plate and are discharged out through the discharge port into the inside of the collection box for automatic collection, achieving the effect of automatically cleaning and removing the filtered impurities.

[0017] 3. In this invention, after the stones and other impurities on the inner bottom surface of the rotating frame are discharged out, continue to control the rotating frame to rotate clockwise, and drive the two filter plates originally located on top of the rotating frame to completely rotate into the inside of the primary crushing box. Control the two filter plates to rotate and reset in the direction away from each other, so that the clamped and fixed cable material can slide out to the central position inside the primary crushing box, facilitating the rapid crushing process by the two crushing rollers; and the rotating frame located on top of the primary crushing box can then block the top opening of the primary crushing box to prevent the cable material being crushed from splashing out through the top opening of the primary crushing box.

[0018] 4. In this invention, if the cable material becomes blocked inside the primary crushing box, to prevent the blockage from getting worse and quickly handle the blockage situation, at this time, control the sealing plate to rotate downward to open, and then control the rotating frame to drive the cleaning brush at one end of the other filter plate to rotate into the inside of the primary crushing box. With the help of the two first sliders moving in the corresponding first chutes in the direction close to the sealing plate, the cleaning brush can automatically push and clean the blocked cable material outward, facilitating the rapid handling of the cable material blockage situation. Moreover, with the mutual cooperation between the cleaning brush and other components, it can also avoid the manual cleaning method, improve the safety during the handling of the cable material blockage situation, and thus improve the overall applicability of the device.

[0024] As a technical optimization scheme of the present invention, the pulverizing mechanism includes two pulverizing rollers 15. Both pulverizing rollers 15 are rotatably installed inside the primary pulverizing box 3 through the rotating shafts arranged at both ends. Two first driving motors are preset on the outer wall of one side of the primary pulverizing box 3, and the output ends of the two first driving motors are respectively connected to the corresponding rotating shafts. The two first driving motors drive the two pulverizing rollers 15 to rotate in opposite directions inside the primary pulverizing box 3 to perform a primary pulverizing treatment on the cable materials entering the inside of the primary pulverizing box 3.

[0025] As a technical optimization scheme of the present invention, the driving mechanism includes first sliding grooves 9 opened on the outer walls on both sides of the primary pulverizing box 3. First sliding blocks 12 are installed inside both first sliding grooves 9. Moving blocks 17 are installed at the ends of both first sliding blocks 12 away from the first sliding grooves 9.

The two first linear motors can drive the two first sliding blocks 12 to move back and forth inside the corresponding first sliding grooves 9, thereby driving the corresponding moving blocks 17 to move back and forth and adjust on the outer walls on both sides of the primary pulverizing box 3. Third driving motors are preset inside both moving blocks 17, and the output ends of the two third driving motors are respectively connected to the rotating parts of the two rotating blocks 18, so as to drive the two rotating blocks 18 to perform rotational adjustment.

[0026] As a technical optimization solution of the present invention, the tops of the two rotating blocks 18 are both connected to a housing 20 through a first electric telescopic rod 19. The rotating frame 6 is rotatably installed between the two housings 20. A second driving motor 21 is installed inside one of the housings 20, and the output end of the second driving motor 21 is connected to the rotating frame 6. The telescopic ends of the two first electric telescopic rods 19 can drive the housing 20, the second driving motor 21, and the rotating frame 6 to move up and down for adjustment; the second driving motor 21 can drive the rotating frame 6 to rotate between the two housings 20 for adjustment.

[0027] As a technical optimization solution of the present invention, second sliding grooves 22 are provided on the inner walls of both sides of the rotating frame 6. Second sliding blocks 23 are installed inside the two second sliding grooves 22. The closer ends of the two filter plates 14 are rotatably connected to the two second sliding blocks 23. Second linear motors are preset inside the two second sliding grooves 22. The two second linear motors can drive the two second sliding blocks 23 to move back and forth inside the corresponding second sliding grooves 22, and then drive the two filter plates 14 to move back and forth inside the rotating frame 6 for adjustment; and two first driving devices are preset inside one of the second sliding blocks 23, and the output ends of the two first driving devices are respectively connected to the rotating parts at one end of the two filter plates 14, so as to be able to drive the two filter plates 14 to rotate between the two second sliding blocks 23 for adjustment.

[0028] As a technical optimization solution of the present invention, two second electric telescopic rods 26 are installed inside the two filter plates 14. An installation plate 24 is jointly installed at the telescopic ends of the two second electric telescopic rods 26. A cleaning brush 29 and a blowing head 27 are respectively installed on the outer walls of the two installation plates 24 away from each other. During the telescopic process of the telescopic ends of the two second electric telescopic rods 26, the corresponding installation plate 24 can be driven to move for adjustment; the blowing head 27 can be connected to a preset blowing device outside through a pipeline, so that the wind generated by the preset blowing device outside can be discharged outward through the blowing head 27.

[0029] As a technical optimization solution of the present invention, a plurality of air outlets 28 are provided inside the blowing head 27. Two protection plates 25 for shielding and protecting the cleaning brush 29 and the air outlets 28 are rotatably installed on the outer walls of the two installation plates 24 away from each other. The wind entering the inside of the blowing head 27 can be discharged outward through the plurality of air outlets 28 provided; two second driving devices are preset on the outer walls of the two installation plates 24 away from each other, and the output ends of the two second driving devices are respectively connected to the rotating parts at one end of the two protection plates 25, so as to be able to drive the two protection plates 25 to rotate on the outer wall of the installation plate 24 for adjustment.

[0030] As a technical optimization solution of the present invention, an opening is formed on the outer wall of one side of the primary crushing box 3, and a sealing plate 10 is rotatably installed inside the opening. A third driving device is preset on the outer wall of one side of the primary crushing box 3, and the output end of the third driving device is connected to the rotating part of one end of the sealing plate 10, so as to drive the sealing plate 10 to rotate and adjust inside the opening.

[0031] As a technical optimization solution of the present invention, a plurality of discharge ports 8 for discharging stone impurities are formed on the outer wall of the other side of the primary crushing box 3. A guiding plate 16 is installed on the inner wall of the primary crushing box 3 near the discharge port 8, and a collection box 7 is slidably installed on the outer wall of the primary crushing box 3 near the discharge port 8. After the rotating frame 6 rotates clockwise downward by a certain angle, the right end of the rotating frame 6 abuts against the top of the guiding plate 16, so that the impurities falling on the inner bottom surface of the rotating frame 6 can slide to the top of the guiding plate 16, and are discharged out through the discharge port 8 along the guidance of the guiding plate 16 and temporarily stored and collected inside the collection box 7, so as to achieve the effect of automatically cleaning and removing the filtered impurities.

[0032] As a technical optimization solution of the present invention, two third chutes 11 are formed on the outer wall of one side of the fixing frame 2, and third sliders 13 are installed inside both third chutes 11. The ends of the two third sliders 13 far away from the third chutes 11 are jointly installed with a moving plate 5, and a secondary crushing box 4 is placed on the top of the moving plate 5. Third linear motors are preset inside both third chutes 11, and the two third linear motors can drive the two third sliders 13 to move up and down inside the corresponding third chutes 11, and then drive the moving plate 5 and the secondary crushing box 4 placed on its top to move up and down and adjust below the primary crushing box 3.

[0033] In this embodiment, the cable material object to be crushed is pre-processed into polyvinyl chloride cable skins with the same length, so as to avoid the length of the cable material being too long or too short, resulting in the crushing quality not meeting the expectations.

[0034] In the present invention, when the user uses the device, such as Figure 1 、 Figure 4 and Figure 7As shown in the figure, the cable material to be crushed is placed on the top of the rotating frame 6 and on top of the two filter plates 14. First, by controlling the two second sliders 23 to move back and forth inside the corresponding second sliding grooves 22, the two filter plates 14 can be driven 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 can be synchronously shaken slightly. Since the cable materials have the same length and a large volume, they cannot fall downward from the inside of the rotating frame 6 during the process of driving them to shake slightly, but it can ensure that the stones and other impurities doped inside can fall upward from the filter grooves inside the two filter plates 14 onto the inner bottom surface of the rotating frame 6 for temporary storage treatment, achieving the effect of pre-filtering and removing the stones and other impurities inside the cable material to be crushed, and avoiding the problem that such impurities enter the inside of the primary crushing box 3 together and cause damage to the crushing mechanism.

[0035] After filtering and removing the stones and other impurities doped inside the cable material, the two filter plates 14 can be controlled to rotate upward together. As Figure 4 shown in the figure, the two filter plates 14 can be driven to move the cable material temporarily stored on their tops towards the center position, and can clamp and fix the cable material at the same time. Then, the two third sliders 13 can be controlled to move upward inside the corresponding third sliding grooves 11, driving the moving plate 5 and the secondary crushing box 4 to move upward together until the distance between the top end of the secondary crushing box 4 and the primary crushing box 3 is adjusted to the minimum state. Then, control the second driving motor 21 to drive the rotating frame 6 to slowly rotate clockwise downward on the top of the primary crushing box 3 until it abuts against the top of the guiding plate 16, so that the stones and other impurities temporarily stored on the inner bottom surface of the rotating frame 6 slide down onto the top of the guiding plate 16 and are discharged outward through the discharge port 8 into the inside of the collection box 7 for automatic collection, achieving the effect of automatically cleaning and removing the filtered impurities.

[0036] After the stones and other impurities on the inner bottom surface of the rotating frame 6 are discharged outward, the rotating frame 6 can be continuously controlled to rotate clockwise, and the two filter plates 14 originally located on the top of the rotating frame 6 can be driven to completely rotate into the inside of the primary crushing box 3. At this time, the two filter plates 14 can be controlled to rotate and reset in the direction away from each other, so that the clamped and fixed cable material can be discharged to the center position inside the primary crushing box 3, facilitating the two crushing rollers 15 to quickly crush it; and the rotating frame 6 located on the top of the primary crushing box 3 can block the top opening of the primary crushing box 3, preventing the cable material being crushed from splashing out from the top opening of the primary crushing box 3.

[0037] After the two crushing rollers 15 perform a primary crushing treatment on the cable material, the cable material can be discharged downward from the bottom of the primary crushing box 3 into the inside of the secondary crushing box 4. With the help of the relevant crushing equipment arranged inside the secondary crushing box 4, the cable material can be crushed more finely, facilitating the subsequent reprocessing and production of the cable material.

[0038] After the two crushing rollers 15 have been crushing the cable material for a period of time, the internal temperature of the two crushing rollers 15 rises. In order to prevent the temperature of the two crushing rollers 15 from being too high, which may cause the cable material to melt and adhere to the surface of the crushing rollers 15 during the crushing process, the two crushing rollers 15 can be controlled to stop working after the two crushing rollers 15 have finished crushing the cable material inside the primary crushing box 3. Then, the two filter plates 14 are controlled to rotate upward to an inclined state inside the rotating frame 6. The rotating frame 6 itself is controlled to rotate downward 90 degrees clockwise at the top of the primary crushing box 3 so that it is in a vertical state at this time, and the air blowing head 27 provided at one end of one of the filter plates 14 is driven to rotate to the inside of the primary crushing box 3. The two corresponding protective plates 25 are controlled to rotate and open in opposite directions. After the blockage of the multiple air outlets 28 is released, the external preset air blowing device is controlled to start. The multiple air outlets 28 can discharge wind toward the two crushing rollers 15, perform air-cooling and heat dissipation treatment on the two crushing rollers 15, and move back and forth in the corresponding first slide grooves 9 with the help of the two first sliding blocks 12, so as to drive the multiple air outlets 28 to perform more comprehensive heat dissipation and temperature reduction treatment on the two crushing rollers 15, improve the heat dissipation efficiency of the two crushing rollers 15, so that the temperature of the two crushing rollers 15 is quickly reduced, and continue to be put into the subsequent crushing processing of the cable material; and in the process of cooling and dissipating the two crushing rollers 15, the multiple air outlets 28 can also drive the multiple air outlets 28 to move and adjust inside the first crushing box 3 with the help of the extension and contraction of the extension ends of the two first electric telescopic rods 19, so that the multiple air outlets 28 can also blow the cable material attached to the inner wall of the first crushing box 3 downward and discharge it to the interior of the second crushing box 4 below, indirectly having an automatic cleaning effect on the first crushing box 3.

[0039] During the process of the cable material being crushed by the two crushing rollers 15 when it enters the interior of the first-stage crushing box 3, due to wear of the crushing rollers 15 after long-term use, or due to other relatively hard rigid materials being doped in the cable material, the cable material becomes blocked between the two crushing rollers 15. To avoid the aggravation of the blockage and quickly handle the blocked situation, at this time, the sealing plate 10 can be controlled to rotate downward to open, and then the rotating frame 6 is controlled to rotate downward counterclockwise by 90 degrees, driving the cleaning brush 29 at one end of the other filter plate 14 to rotate into the interior of the first-stage crushing box 3 and above the two crushing rollers 15. After controlling the two corresponding protection plates 25 to rotate and open in the direction away from each other, the telescopic ends of the two corresponding second electric telescopic rods 26 are controlled to extend together, driving the cleaning brush 29 to move downward to the blocked part. By means of the two first sliders 12 moving in the corresponding first sliding grooves 9 in the direction close to the sealing plate 10, the cleaning brush 29 can automatically push and clean the blocked cable material outward, facilitating the quick handling of the cable material blockage situation. Moreover, with the mutual cooperation between the cleaning brush 29 and other components, it is also possible to avoid the manual cleaning method, improve the safety during the handling of the cable material blockage situation, and thus improve the overall applicability of the device.

[0040] Meanwhile, after the two crushing rollers 15 are used for a period of time, it is inevitable that some cable material will adhere to their surfaces. The above steps for handling the blockage of the cable material inside the first-stage crushing box 3 can be repeated, enabling the cleaning brush 29 to move inside the first-stage crushing box 3. By cooperating with the slow rotation of the two crushing rollers 15, the partial cable material adhering to the surfaces of the two crushing rollers 15 can be automatically brushed and cleaned, improving the applicability of the cleaning brush 29 itself. After the cleaning brush 29 cleans the cable material on the surfaces of the two crushing rollers 15, the rotating frame 6 can also be controlled to rotate and adjust, driving the blowing head 27 to rotate into the interior of the first-stage crushing box 3 to blow and clean the cleaned cable material, improving the cleaning and removal efficiency of the cleaned cable material, which is conducive to the subsequent continuous crushing work of the two crushing rollers 15 on the cable material.

[0041] If it is necessary to disassemble and overhaul the two crushing rollers 15 inside the first-stage crushing box 3, in order to facilitate the removal of the disassembled crushing rollers 15 from the interior of the first-stage crushing box 3, at this time, the telescopic ends of the two first electric telescopic rods 19 can be controlled to extend upward together, pushing the rotating frame 6 and other components to move upward to an appropriate height at the top of the first-stage crushing box 3. Then, the two rotating blocks 18 are controlled to drive the two first electric telescopic rods 19, the rotating frame 6 and other components to rotate clockwise downward by 90 degrees together, driving the rotating frame 6 and other components to rotate to the right side of the first-stage crushing box 3, enabling the staff to conveniently disassemble the two crushing rollers 15 from the top opening part of the first-stage crushing box 3 and avoiding the rotating frame 6 and other components from obstructing the disassembly of the two crushing rollers 15. After controlling the rotation of components such as the rotation frame 6 until they reach 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 as Figure 10 shown, control the two rotating blocks 18 to continue rotating downward, driving components such as the rotation frame 6 to rotate to the bottom of the primary crushing box 3. Then, control the telescopic ends of the two first electric telescopic rods 19 to continue extending downward to provide space for the rotational adjustment of the rotation frame 6. Next, control the rotation frame 6 to perform a 180-degree rotational adjustment between the two housings 20, driving components such as the two filter plates 14 to rotate close to the bottom end of the primary crushing box 3. Then, control the two filter plates 14 to rotate upward together into an inclined state, so that at this time, the two protection plates 25 at the tops of the two filter plates 14 are both located at the bottom of the two crushing rollers 15. As the telescopic ends of the two first electric telescopic rods 19 contract, drive the protection plates 25 at the tops of the two filter plates 14 to abut against the crushing rollers 15, and continue to control the telescopic ends of the two first electric telescopic rods 19 to contract. Then, with the help of components such as the protection plates 25 abutting against the two crushing rollers 15, the two disassembled crushing rollers 15 can be assisted to move upward inside the primary crushing box 3 until the two crushing rollers 15 move upward to an appropriate height. Then, control the sealing plate 10 to rotate downward to open, and the staff can take out the two crushing rollers 15 outward on the other side of the primary crushing box 3, so as to achieve the effect of facilitating the removal and maintenance of the two crushing rollers 15, and further improve the applicability of components such as the drive mechanism, the rotation frame 6, and the two filter plates 14.

[0042] After the device is used, the secondary crushing box 4 will be removed from the top of the moving plate 5. At this time, control the two third sliders 13 to move upward inside the corresponding third chutes 11, driving the moving plate 5 to block the bottom opening of the primary crushing box 3, and the rotation frame 6 can block 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, and improving the protection effect of the primary crushing box 3 when not in use.
