Description

Technical Field

[0001] This utility model relates to the technical field of wire and cable recycling and processing equipment, specifically to a double-roller wire and cable chipper. Background Technology

[0002] A double-roller cable shaving machine is a specialized machine used in the wire and cable industry for precise cutting of the cable sheath (insulation layer or sheath layer). Through the coordinated operation of two rollers and a sharp cutting blade, it shaves the cable sheath into thin sheets of a specific thickness, and is widely used in material testing, production processing, and quality control.

[0003] Chinese patent CN219627249U discloses a double-roller wire and cable chipper, including a support frame. A pad is fixedly mounted on the bottom end of the support frame, and two electric push rods are fixedly mounted on the bottom surface of the support frame. A top plate is fixedly mounted on the bottom end of the two electric push rods, and a first cutter is fixedly mounted on one side of the bottom surface of the top plate. The bottom end of the push rods can reciprocate by extending or shortening, driving the top plate to move, and simultaneously driving the first and second cutters to move. Before use, the position of the second cutter needs to be adjusted according to the diameter of the wire or cable. This is achieved through an adjustment mechanism, moving the second cutter, originally located on the left, closer to the first cutter. The slider on the second cutter can move inside a groove. Through the cooperation of the first and second cutters, their special shape design allows them to fit together, limiting the movement of the wire or cable on both sides. This provides high flexibility, simple operation, and convenient use.

[0004] When using the twin-roller cable chipper in the relevant technology, the cable is subjected to the lateral force of the cutter during chipping, which makes the cable prone to lateral displacement or angular rotation. This results in the cable chipping arc deviation and uneven chipping, leading to a high scrap rate after chipping, wasting cable raw materials and increasing production costs. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a double-roller wire and cable chipper, which solves the technical problem that when the cable is chipped, it is subjected to the lateral force of the cutter, which makes the cable prone to lateral displacement or angular rotation, resulting in the cable chipping arc deviation and uneven chipping. This leads to a high scrap rate of the chipped cable, waste of cable raw materials, and increased production costs.

[0006] According to one aspect, at least one embodiment of the present invention provides a double-roller wire and cable chipper, comprising: a chipper body, a base mounted on the top of the chipper body, a positioning component mounted on the side of the base, a cleaning component mounted on the back of the chipper body, and a control panel mounted on the front of the chipper body; The positioning component includes a mounting slot, in which a servo motor is installed.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-3 As shown, it illustrates a double-roller wire and cable chipper according to an embodiment of the present invention. The chipper body 1 has a base 4 installed on the top of the chipper body 1, a positioning component 2 installed on the side of the base 4, a cleaning component 3 installed on the back of the chipper body 1, and a control panel 5 installed on the front of the chipper body 1. The positioning component 2 includes a mounting groove 21, inside which a servo motor 22 is installed. A bidirectional screw 23 is fixed to the output end of the servo motor 22. Sliding blocks 24 are threaded to both sides of the bidirectional screw 23. A positioning plate 25 is fixed to one side of the top of the sliding block 24. A rotating shaft 26 is fixed to the top of the positioning plate 25. Torsion springs 27 are sleeved on both sides of the rotating shaft 26. A limit block 28 is rotatably connected to the rotating shaft 26. The limit block 28 is used to vertically position the cable to prevent the cable from moving upward when it is clamped before entering the roller. The torsion springs 27 are used to reset the rotation of the limit block 28, so that the limit block 28 can position cables with larger diameters, increasing the flexibility of the positioning plate 25.

[0024] In some examples, the side of the limiting block 28 is provided with a groove, and the grooves of the limiting blocks 28 on both sides of the bidirectional screw 23 are staggered. The staggered arrangement of the grooves on both sides of the limiting block 28 ensures that when positioning a cable with a small diameter, the limiting blocks 28 on both sides will not collide during the staggered process.

[0025] In some examples, the positioning plate 25 has a groove 29, and a protective layer 210 is installed on the surface of the positioning plate 25. The groove 29 facilitates the clamping plate 213 to pass through the positioning plate 25 to clamp the cable. The protective layer 210 is made of polyurethane, and the surface of the protective layer 210 is provided with grooves to facilitate the sliding of the cable.

[0026] In some examples, a support block 211 is fixed to the top of the sliding block 24 away from the positioning plate 25, and an electric push rod 212 is installed on the side of the support block 211 close to the positioning plate 25. A clamping plate 213 is fixed to the other end of the electric push rod 212. The outer side of the clamping plate 213 is set to be arc-shaped to facilitate better stable clamping of the cable surface. In some examples, the top of the base 4 has a rotating groove 216, and the bidirectional screw 23 is rotatably connected in the rotating groove 216. A support plate 214 is fixed at the center of the rotating groove 216, and a positioning sensor 215 is installed on the top of the support plate 214. The positioning sensor 215 is an FPES-L951 sensor used for positioning the cable.

[0027] For example, such as Figure 3 As shown, the cable is first placed on the base 4 and positioned on top of the support plate 214, allowing the positioning sensor 215 to sense the cable. Then, the control panel 5 controls the servo motor 22 to drive the bidirectional screw 23 to rotate, allowing the sliding blocks 24 on both sides of the bidirectional screw 23 to move and clamp synchronously. When the positioning plate 25 positions the cable, the top of the cable abuts against the surface of the limiting block 28. When the cable diameter is large, the limiting block 28 rotates on the rotating shaft 26 via the torsion spring 27, thus allowing the positioning plate 25 and the limiting block 28 to position the cable more stably. Then, the control panel 5 controls the electric push rod 212 to push the clamping plate 213, causing the clamping plate 213 to pass through the positioning plate 25 and clamp the cable. When the cable is placed on the roller, the roller drives the cable to move towards the cutter, allowing the cable to slide through the protective layer 210 on the surface of the positioning plate 25, thus keeping the cable in a stable position during the chipping process.

[0028] like Figures 4-5 As shown, it illustrates a double-roller wire and cable chipper in another embodiment of the present invention. The cleaning component 3 includes a collection box 31, a negative pressure box 32 is installed on the side of the collection box 31, a suction pump 33 is threadedly installed on the other end of the negative pressure box 32, suction pipes 34 are installed on both sides of the collection box 31, and a suction port 35 is opened on the inner side of the chipper body 1.

[0029] In some examples, a partition plate 39 is fixed inside the collection box 31, an inclined plate 38 is installed on the top of the partition plate 39, a rotating shaft 310 is rotatably connected to the side of the partition plate 39, and a movable plate 311 is fixed on the rotating shaft 310. The inclined plate 38 facilitates the collection of debris and other materials sucked in, and places the debris to hang on the inner wall of the collection box 31. The partition plate 39 divides the inside of the collection box 31 into two spaces. The space at the top is used to collect and compress debris and other materials, and the space at the bottom is used to clean and remove the compressed debris. The movable plate 311 and the rotating shaft 310 are both controlled by the control panel 5, so that the compressed debris can be transported to the bottom space of the collection box 31. In some examples, a cylinder 36 is fixed to the top of the collection box 31, and a compression plate 37 is fixed to the bottom of the cylinder 36. The bottom of the compression plate 37 is provided with a groove to facilitate the squeezing and compression of the accumulated debris, thereby saving space inside the collection box 31 and accommodating more debris.

[0030] For example, such as Figure 5 As shown, when the cutting device at the top of the chipper body 1 chips the cable, the resulting debris remains on the base 4. Then, the suction pump 33 on the side of the negative pressure box 32 is controlled by the control panel 5, so that the negative pressure box 32 forms a negative pressure suction state to the inside of the collection box 31. The debris on the surface of the platform of the base 4 is sucked through the suction port 35 at the other end of the suction pipe 34, so that the debris enters the collection box 31 for collection. The debris slides down the inclined plate 38 to the surface of the movable plate 311. Then, the cylinder 36 is controlled by the control panel 5 to push the compression plate 37 to compress the debris, so that the debris gathers and is compressed into blocks. Then, the rotating shaft 310 is controlled by the control panel 5 to rotate, so that the rotating shaft 310 drives the movable plate 311 to rotate downward, so that the debris blocks fall to the bottom of the collection box 31. The operator can then periodically open the cover plate on the back of the collection box 31 and clean the debris blocks.
