Description

Technical Field

[0001] The utility model belongs to the technical field of cable peeling equipment, in particular to a cable peeling equipment for recycling. Background Art

[0002] Scrap cables are a kind of waste containing metal materials. They can be recycled by peeling. How to peel the scrap cables is an important link in the recycling process of scrap cables. First of all, the scrap cables need to be disassembled to separate the outer insulation layer and the inner conductor layer for further processing. Usually, a stripping machine can be used to strip the cables. The stripping machine is a professional equipment for stripping scrap cables. It can quickly and efficiently cut off the outer insulation layer of the cable. The stripping machine removes the outer insulation layer by rotating and cutting the blade, exposing the internal metal conductor. After the scrap cables are peeled, the internal metal conductor can be recycled.

[0003] However, the reason why the waste cable can move on the blade is that it can move normally through the action of the upper and lower cutting wheels that are coaxial and concentric with the blade. Because the friction generated by the blade and the waste cable is not enough to drive the movement of the waste cable, the waste cable must be clamped by the grooves on the cutting wheels at the upper and lower ends, thereby generating greater friction to drive the movement of the cable.

[0004] However, in order to completely cut the outer skin of the waste cable, the outer diameter of the blade must be larger than the outer diameter of the cutting wheel. This results in the waste cable first contacting the blade during cutting, and a notch is cut in the waste cable before it can contact the cutting wheel. Before the waste cable can be normally acted upon by the cutting wheel, it is not assisted by a relatively effective external mechanical force. For some thicker waste cables, a greater force is required to cut the insulating material of the outer skin, so the waste cable cannot be quickly fed into the cutting wheel. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 8 As shown, the embodiment of the utility model provides a cable recycling peeling device, including a stand 1, the top longitudinal beam and the upper surface of the side beam of the stand 1 are respectively fixedly connected with a positioning mechanism 2, a movable shaft 3 is rotatably sleeved in the positioning mechanism 2, a cutting wheel 4 is fixedly sleeved at one end of the movable shaft 3, and a gear 5 is fixedly sleeved at the other end of the movable shaft 3, a shaft sleeve 6 is fixedly connected to the lower surface of the cross beam and the side beam corresponding to the positioning mechanism 2, a fixed shaft 7 is rotatably sleeved inside the shaft sleeve 6, and another cutting wheel 4 is fixedly sleeved at one end of the fixed shaft 7, The other end of the fixed shaft 7 is fixedly sleeved with a gear 2 9, one side of the platform 1 is fixedly connected with a workbench 10, a motor 11 is fixedly installed in the middle of the longitudinal beam inside the platform 1, and a gear 3 12 is fixedly sleeved on the output end of the motor 11, and a chain tightening mechanism 13 is fixedly connected to the crossbeam between the longitudinal beam at the top of the platform 1 and the side beam on the other side, and a gear 4 14 is rotatably sleeved on the chain tightening mechanism 13, and a chain 8 is transmission-connected to the outer teeth of the gear 4 14, and the chain groove of the chain 8 is meshed with the outer edges of the gear 1 5, the gear 2 9, and the gear 3 12;

[0028] The cutting wheel 4 includes an internal gear 41, a blade 42 is fixedly connected to the middle of the internal gear 41, outer wheels 43 are added on both sides of the internal gear 41, clamping springs 44 are added on the outer sides of the outer wheels 43 on both sides, and retaining rings 45 are added on both sides of the clamping springs 44. The outer retaining ring 45 is fixedly sleeved on the shaft, and the inner retaining ring 45 is movably sleeved on the shaft. The two cutting wheels 4 are respectively located on the movable shaft 3 and different shafts. The upper and lower cutting wheels 4 are located on the same vertical line, and the upper and lower blades 42 are located on the same plane.

[0029] The beneficial effects of the above technical solution are: a blade 42 fixedly connected to the middle part of the internal gear 41, outer wheels 43 added on both sides of the internal gear 41, clamping springs 44 added on the outside of the outer wheels 43 on both sides, and retaining rings 45 added on both sides of the clamping springs 44. The outer retaining ring 45 is fixedly sleeved on the shaft, and the inner retaining ring 45 is movably sleeved on the shaft. When a cable needs to enter, the cable can contact the outer wheel 43 before contacting the blade 42. At the same time, the clamping springs 44 on both sides tighten the outer wheel, which will cause the outer wheel and the cable to generate greater friction, and the cable is sent into the blade 42 by applying external force to the cable through the outer wheel.

[0030] The outer retaining ring 45 is fixedly sleeved on the shaft, and the outer retaining ring 45 can be used as a fixed support point. The inner retaining ring 45 is movably sleeved on the shaft, and the inner retaining ring 45 can be used as a movable support point. When the inner retaining ring is squeezed by the outer wheel 43, the inner retaining ring 45 transmits the force to the clamping spring 44. The clamping spring 44 is compressed and generates elastic potential energy, which is transmitted to both sides. Since the outer retaining ring 45 is a fixed support point, it will not be displaced, so that all the elastic potential energy is transmitted to the inner retaining ring 45, so that the outer wheels 43 on both sides are clamped inward.

[0031] In this embodiment, the outer wheel 43 includes a wheel body 431, and the outer dimensions of the wheel body 431 are a stepped circular wheel. An outer tooth groove 432 is opened on the outer wall of the wheel body 431, and a circular groove is opened on the stepped top of the wheel body 431. The diameter of the circular groove of the wheel body 431 is equal to the diameter of the inner edge of the inner gear 41. An inner tooth groove 433 is opened inside the circular groove of the wheel body 431, and all the outer edges of the inner tooth groove 433 are meshed with all the outer edges of the inner gear 41.

[0032] The beneficial effects of the above technical solution are: the outer wheel 43 is designed with a stepped structure. When a cable enters the equipment, it will first contact the inclined surface of the outer wheel 43. The external tooth groove 432 opened on the inclined surface of the wheel body 431 can increase the contact area with the cable surface and increase the friction with the cable. The internal tooth groove 433 opened on the inner wall of the circular groove inside the wheel body 431 cooperates with the tooth groove of the internal gear 41 to prevent the outer wheel 43 from being unevenly stressed on the upper and lower sides during operation, thereby causing asymmetry, resulting in the cable surface being unable to run along the prescribed route.

[0033] In this embodiment, the positioning mechanism 2 includes a frame 21, and the upper and lower ends of both sides of the frame 21 are fixedly connected with sliding rods 22. The outer wall of the sliding rod 22 is movably sleeved with a support spring 23. The outer wall of the sliding rod 22 on both sides is slidably sleeved with a sliding shaft sleeve 24. The top of the support spring 23 supports the sliding shaft sleeve 24. A screw rod 25 is assembled in the middle of the frame at the top of the frame 21. The outer thread of the screw rod 25 cooperates with the thread on the frame 21. The top of the screw rod 25 is fixedly connected with a turntable 26, and the bottom of the screw rod 25 supports the sliding shaft sleeve 24.

[0034] The beneficial effects of the above technical solution are: the movable shaft 3 is rotated and sleeved in the positioning mechanism 2, and the cutting wheel 4 is fixedly sleeved at one end of the movable shaft 3, so that the cutting wheel 4 can be adjusted up and down. When cables of different sizes need to be processed, a reasonable distance can be adjusted according to the diameter of the cable to be processed, which can prevent the cable from being unable to enter the equipment due to its large size, so that the equipment can adapt to processing cables of different sizes.

[0035] In this embodiment, the sliding sleeve 24 includes a base 241, which is a rectangular parallelepiped with a semi-cylindrical middle portion of the upper layer removed. A cover plate 242 is fixedly mounted on the upper surface of the base 241. The middle portion of the cover plate 242 is bent into a semicircular arc, and the radius of the arc is the same as the semi-cylindrical groove on the base 241. The two surround a complete set of holes, and a limiting hole 243 is provided in the middle of the contact points on both sides of the base 241 and the cover plate 242.

[0036] The beneficial effect of the above technical solution is: by assembling the base 241 and the cover plate 242, it is convenient for the later maintenance and replacement of the movable shaft 3. The sleeve hole formed by the two can flexibly sleeve the movable shaft 3 without affecting the normal operation of the movable shaft. The two limit holes 243 are opened on both sides of the sliding sleeve 24, which can cooperate with the sliding rod 22 to move up and down. The position is fixed and will not be offset, which can ensure the normal operation of the equipment.

[0037] In this embodiment, the workbench 10 includes a bracket 101, and two brackets 101 are fixedly connected to the legs of the platform 1 located on one side of the cutting wheel 4. The top of the bracket 101 is fixedly connected to a platform 102. A square hole is reserved in the middle of the platform 102, and the cutting wheel 4 is inserted into the square hole. The upper surface of the platform 102 is located on the side of the feed port and is fixedly connected to two baffle rods 103. The surface of the baffle rods 103 is smooth. The baffle rods 103 are arranged side by side and parallel to the side of the platform. There is a width distance between the two baffle rods 103 that can pass the cable.

[0038] The beneficial effect of the above technical solution is as follows: before the cable is sent into the equipment, the cable is passed through the baffle 103 on the workbench 10, so that the cable path of the first section entering the equipment can be fixed, preventing the cable that has entered the equipment from being deviated, causing equipment failure and inability to operate continuously. The surface of the baffle 103 is smooth, and the friction generated with the cable will be reduced, which is beneficial to guiding the movement direction of the cable end.

[0039] In this embodiment, the chain tightening mechanism 13 includes an axle fork 131, and an extension rod 132 is rotatably sleeved in the middle part of the axle fork 131. The upper surface of one end of the extension rod 132 is fixedly connected with a rod fork 133, and the inside of the rod fork 133 is rotatably sleeved with a cylinder 134, and the other end of the cylinder 134 is rotatably sleeved with a fixed rod 135, one end of the fixed rod 135 is fixedly connected to the inner side of the side beam of the platform 1, and one side of the lower end of the extension rod 132 is fixedly connected with a rotating shaft 136.

[0040] The beneficial effect of the above technical solution is: if the distance of the cutting wheel 4 needs to be reduced, the sliding sleeve 24 needs to be lowered, and the movable shaft 3 moves downward accordingly, and the cooperation between the chain 8 and other gears will be loosened. At this time, the external pressure of the cylinder 134 on the chain tightening mechanism 13 is reduced, and the internal rod will extend, thereby achieving the effect of tightening the chain 8.

[0041] In this embodiment, gear one 5, gear three 12, and gear four 14 are transmission connected to the inner side of chain 8, and the rotation direction of gear one 5 and gear four 14 is the same as that of gear three 12. Gear two 9 is transmission connected to the outer side of chain 8, and the rotation direction of gear two 9 is opposite to that of gear three 12.

[0042] The beneficial effects of the above technical solution are: the rotation directions of gear 1 5 and gear 2 9 are opposite, so the effect of the two gears rolling the cable inward can be achieved, and the movement of the four gears is driven by only one motor 11, which simplifies the equipment, facilitates subsequent maintenance, and saves energy costs.

[0043] Working principle and usage process:

[0044] First, adjust the positioning mechanism 2 according to the size of the cable to be processed, and adjust the rise or fall of the screw rod 25 by rotating the turntable 26. The bottom of the screw rod 25 presses against the sliding sleeve 24, and the bottom of the sliding sleeve 24 is supported by the support spring 23, so that the height of the sliding sleeve 24 can be adjusted, thereby adjusting the distance between the two cutting wheels 4. Then, when the sliding sleeve 24 is lowered, the movable shaft 3 moves down accordingly, and the cooperation between the chain 8 and other gears will be loosened. At this time, the external pressure of the cylinder 134 on the chain tightening mechanism 13 is reduced, and the internal rod will extend, thereby achieving the effect of tightening the chain 8. At this time, the starting motor 11 drives gear 1 5, gear 3 12, and gear 4 14 through the chain 8, and at the same time drives gear 2 9 in the reverse direction. Gear 1 5 drives the movable shaft 3 to rotate, the movable shaft 3 drives the cutting wheel 4 to rotate, and gear 2 9 drives the fixed shaft 7 Rotate, the fixed shaft 7 drives the other cutting wheel 4 to rotate, which can form the effect of the two cutting wheels 4 rotating inward, and the cable is sent into the front of the equipment. Now the cable is passed through the baffle 103 on the workbench 10, which can fix the cable path of the previous section entering the equipment, and prevent the cable that has entered the equipment from being deviated, resulting in equipment failure and inability to operate continuously. Due to the designed step structure of the outer wheel 43, when a cable enters the equipment, it will first contact the inclined surface of the outer wheel 43, and the outer tooth groove 432 on the outer wheel 43 increases the friction with the cable. At the same time, the clamping springs 44 on both sides tighten the outer wheel 43, which will cause the outer wheel 43 and the cable to generate a larger friction force, so that the outer wheel 43 will first work on the cable, and the cable will first be sent into the blade 42, and then contact the inner gear 41, thereby completing the work of cutting the cable sheath.
