Description

Technical Field

[0001] The invention relates to the technical field of waste recycling, in particular to a cable insulation material waste crushing device which is convenient for recycling. Background Art

[0002] Insulating materials are the foundation and guarantee for the development of electrical products, and play a particularly important role in the development of motors and the electrical industry. The development and progress of insulating materials depends on the development of polymer materials and directly restricts and affects the development and progress of electrical products. Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which consist of one or more insulating cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] When recycling cables, the insulating material wrapped around them needs to be stripped off, leaving the inner core or metal wire to be recycled for secondary use. The shape, size and length of the stripped insulating sheath are uneven, which brings great inconvenience to the subsequent recycling process. The waste insulating material needs to be crushed into particles of fixed size for subsequent recycling. The hardness of the waste insulating material is relatively high, which will cause great damage to the cutter when directly crushed. At the same time, the crushing effect is poor, and it is difficult to get the ideal size. Therefore, we designed a cable insulating material waste crushing equipment that is easy to recycle.

[0022] An auxiliary mechanism is arranged in the box and at the rear side of the strip cutting roller.

[0023] Through the above technical scheme, the present application can heat and extrude the waste insulating material into a fixed thickness, which is convenient for subsequent cutting into strips, blocks and recycling.

[0024] Preferably, the auxiliary mechanism includes: a second transmission roller, a second gear, a second sharp tooth, a second chain, a positioning spike and a strip-shaped perforation. The number of the second transmission rollers is two and they are distributed up and down on the rear side of the strip cutting roller, and the two ends of the second transmission roller are movably connected to the inner wall of the box body through bearing four.

[0031] Through the above technical solution, the double-hole air pump of the present application performs air cooling on the waste insulating material between the front baffle and the rear baffle to prevent subsequent adhesion.

[0032] Preferably, the heating assembly includes: a heating plate, a limit groove, an insertion rod and a compression spring, the heating plate is arranged in the feed port, and the front and rear inner walls of the feed port are provided with limit grooves, the insertion rod is inserted in the limit groove, and the end of the insertion rod away from the limit groove is fixedly connected to the corresponding heating plate, the outer side of the insertion rod is movably sleeved with a compression spring, and the two ends of the compression spring are respectively fixedly connected to the inner wall of the feed port and the heating plate.

[0034] Preferably, a side of the heating plate away from the feed port and an outer side of the extrusion roller are both fixedly connected with an anti-sticking oil film, and the anti-sticking oil film is a high temperature resistant release film.

[0035] Through the above technical solution, the present application can avoid the phenomenon of insulation material waste sticking together during heating and extrusion.

[0036] Preferably, an auxiliary groove is opened on the front side of the rear baffle, and the auxiliary groove is symmetrically designed with the cutting hole. The top of the front baffle and the rear baffle are adapted to the extrusion roller. A limiting plate is fixedly connected between the left and right inner walls of the box body and between the two extrusion rollers, and the shape of the limiting plate is adapted to the extrusion roller.

[0037] Through the above technical scheme, when the cutting knife of the present application is cutting, its rear end is located in the auxiliary groove, ensuring that the extruded waste insulating material can be completely cut off to prevent the phenomenon of uncut off. At the same time, through the design of the limiting plate, the inserted waste insulating material can be limited to prevent the phenomenon of deviation.

[0069] An auxiliary mechanism 8 is provided in the box body 1 and at the rear side of the strip cutting roller 71 .

[0070] Through the above technical scheme, the present application can heat and extrude the waste insulating material into a fixed thickness, which is convenient for subsequent cutting into strips, blocks and recycling. The simultaneous cutting into strips and blocks can prevent adhesion during crushing, while enhancing the crushing effect and protecting the service life of the equipment.

[0071] The auxiliary mechanism 8 includes: a second transmission roller 81, a second gear 82, a second sharp tooth 83, a second chain 84, a positioning spike 85 and a strip-shaped perforation 86. There are two second transmission rollers 81, which are distributed up and down on the rear side of the strip cutting roller 71, and the two ends of the second transmission roller 81 are movably connected to the inner wall of the box body 1 through bearing 4. The outer sides of the two ends of the second transmission roller 81 are fixedly sleeved with the second gear 82 and meshed with the driving wheel 73. The outer sides of the two ends of the second transmission roller 81 are also fixedly connected with the second sharp teeth 83, and the outer sides of the second sharp teeth 83 located at the upper and lower positions are movably connected with the second chain 84. The outer side of the second transmission roller 81 is fixedly connected with the positioning spike 85, and the rear baffle 6 is provided with a strip-shaped perforation 86, and the positioning spike 85 passes through the strip-shaped perforation 86.

[0072] Through the above technical solution, the positioning spike 85 of the present application is inserted into the extruded waste insulating material through the strip-shaped perforation 86. On the one hand, it can limit the waste insulating material to ensure good stability when cutting into strips and blocks. On the other hand, the positioning spike 85 can slowly drive the waste insulating material to be transmitted downward when rotating, thereby ensuring the stability of the equipment operation.

[0073] The distance between the two first transmission rollers 74 is greater than the distance between the two second transmission rollers 81 , the second transmission roller 81 located on the top is flush with the bottom of the strip-shaped through-holes 86 , and the strip-cutting holes 711 and the strip-shaped through-holes 86 are staggered.

[0074] Through the above technical scheme, the present application drives the toggle block 713 through the L-shaped block 714 when the first transmission roller 74 rotates, that is, the slitting knife 712 performs slitting, while the second transmission roller 81 drives the positioning spikes 85 for transmission and limiting. The two do not affect each other, and one of the positioning spikes 85 rotates and separates from the insulating material waste after the slitting knife 72 performs slitting, ensuring that it does not affect the slitting action while playing a limiting role in stability. After the first chain 77 moves a certain distance, the L-shaped block 714 separates from the toggle block 713. At this time, the slider 79, the connecting rod 710 and the slitting knife 712 are moved downward and reset by gravity to perform the next slitting process.

[0075] The cutting blades 72 are distributed in a ring shape with the axis of the strip cutting roller 71 as the center, and the angle between the cutting blades 72 and the strip cutting roller 71 is sixty degrees, and the second motor 715 rotates clockwise.

[0076] Through the above technical scheme, the cutting knife 72 of the present application is aligned with the insulating material waste after cutting between the baffle plate 5 and the rear baffle plate 6, so that the cutting knife 72 can just contact between the front baffle plate 5 and the rear baffle plate 6 to perform flush cutting. When the second motor 715 rotates, it drives the first transmission roller 74 and the second transmission roller 81 to reverse, respectively performing the cutting and limiting actions of the positioning spikes 85.

[0077] A double-hole air pump 9 is fixedly installed on the right wall of the box body 1 and corresponds to the position of the front baffle 5. Air inlet holes 10 are opened on the right sides of the front baffle 5 and the rear baffle 6. The air outlet end of the double-hole air pump 9 passes through the box body 1 and is connected with the air inlet hole 10. Air outlet holes 11 are opened on the rear side of the front baffle 5 and the front side of the rear baffle 6, and the air outlet holes 11 are connected with the air inlet hole 10.

[0078] Through the above technical solution, the double-hole air pump 9 of the present application performs air cooling on the waste insulating material between the front baffle 5 and the rear baffle 6 to prevent subsequent adhesion.

[0079] The heating component a includes: a heating plate a1, a limiting groove a2, an insertion rod a3 and a compression spring a4. The heating plate a1 is arranged in the feed port 2.

The outer side of the insertion rod a3 is movably sleeved with a compression spring a4, and the two ends of the compression spring a4 are respectively fixedly connected to the inner wall of the feed port 2 and the heating plate a1.

[0080] Through the above technical solution, the two heating plates a1 of the present application heat the insulating material waste in close contact with the waste material, heating it until it softens, thereby enhancing the convenience of subsequent extrusion and cutting into strips and blocks.

[0081] The side of the heating plate a1 away from the feed port 2 and the outer side of the squeezing roller 3 are both fixedly connected with an anti-sticking oil film 12, and the anti-sticking oil film 12 is a PET high temperature resistant release film.

[0082] Through the above technical solution, the present application can avoid the phenomenon of insulation material waste sticking together during heating and extrusion.

[0083] An auxiliary groove 13 is provided on the front of the rear baffle 6, and the auxiliary groove 13 is symmetrically designed with the cutting hole 711. The top of the front baffle 5 and the rear baffle 6 are adapted to the extrusion roller 3. A limiting plate 14 is fixedly connected between the left and right inner walls of the box body 1 and between the two extrusion rollers 3, and the shape of the limiting plate 14 is adapted to the extrusion roller 3.

[0084] Through the above technical solution, when the cutting knife 712 of the present application is cutting, its rear end is located in the auxiliary groove 13, ensuring that the extruded waste insulating material can be completely cut off to prevent the phenomenon of not being cut off. At the same time, through the design of the limiting plate 14, the inserted waste insulating material can be limited to prevent the phenomenon of deviation.

[0085] When the cable insulation material waste shredding equipment that is easy to recycle is working, the stripped insulation material waste is put into the space between the two heating plates a1 through the feed port 2 and heated, and then inserted downward between the two squeezing rollers 3. At this time, the insulation material waste is easily squeezed into a fixed thickness and enters between the front baffle 5 and the rear baffle 6. The double-hole air pump 9 cools it through the air outlet 11. The second motor 715 rotates to drive the slitting roller 71 to drive the first transmission roller 74 to rotate. The first chain 77 moves to drive the L-shaped block 714 to move and contact the toggle block 713 to drive the connecting rod 710 and The slitting knife 712 moves to cut the extruded insulating material waste into strips. After the first chain 77 moves a certain distance, the L-shaped block 714 disengages from the toggle block 713. At this time, the slider 79, the connecting rod 710 and the slitting knife 712 are reset to perform the next slitting action. At the same time, the slitting roller 71 rotates while driving the second transmission roller 81 to rotate. The positioning spikes 85 penetrate into the insulating material waste to limit and transfer it. The cut insulating material waste is moved out from between the front baffle 5 and the rear baffle 6 and cut into blocks by the rotating slitting knife 72 to ensure that it is finally broken into fixed particles.
