Wire stripping device

Abstract

This invention discloses a wire stripping device, comprising: a base; a wire fixing body disposed on one side of the base, with the wire fixed to the wire fixing body in a lateral posture and one end exposed outwards; and a stripping structure disposed on the other side of the base, which moves closer to or further away from the wire fixing body via a displacement component. The stripping structure includes a seat, a cylinder component, an intermediate body, a pair of mirror-image support arms, and a pair of mirror-image curved connecting rods disposed on the seat. The ends of the two curved connecting rods are respectively provided with a first cutter and a second cutter that can approach each other and partially overlap, and the first and second cutters have opposing V-shaped cutting grooves. This invention, through the mirror-symmetrical support arms combined with the curved connecting rod mechanism, ensures synchronous movement of the two cutters. When the V-shaped cutting grooves of the two cutters overlap, they form a complete circular cutting surface, completing the insulation layer circumferential cutting in one operation. This avoids the problem of traditional single-blade methods requiring wire rotation or multiple cuts, thus improving stripping efficiency.

Description

Technical Field

[0001] This utility model relates to the field of wire recycling technology, specifically, it demonstrates a wire stripping device. Background Technology

[0002] Wires and cables refer to materials used for power, electrical and related transmission purposes. There is no strict boundary between "wires" and "cables". Generally, products with fewer cores, smaller diameter and simpler structure are called wires, and those without insulation are called bare wires. Others are called cables. Conductors with larger cross-sectional areas (greater than 6 square millimeters) are called large cables, and those with smaller cross-sectional areas (less than or equal to 6 square millimeters) are called small wires or building wires.

[0003] Wires and cables consist of one or more insulated conductors, and each of them may have a sheath, a general protective layer and an outer sheath. Cables may also have additional uninsulated conductors.

[0004] Discarded wires and cables usually need to be recycled because the wire cores of the cables have great recycling value. During recycling, the wires and cables need to be stripped. Traditional stripping equipment uses stripping knives, but the stripping effect is generally poor and the stripping efficiency is low. Utility Model Content

[0005] The purpose of this invention is to provide a wire stripping device that is semi-automatic, saving time and effort.

[0006] The technical solution is as follows:

[0007] A wire stripping device, comprising:

[0008] abutment;

[0009] A wire fixing body is located on one side of the base, and the wire is fixed to the wire fixing body in a horizontal position with one end exposed outward.

[0010] The stripping structure is located on the other side of the base and is moved closer to or further away from the wire fixing body via a displacement component; wherein,

[0011] The peeling structure includes a base, a cylinder, an intermediate body, a pair of mirror-image support arms, and a pair of mirror-image curved connecting rods mounted on the base. The telescopic end of the cylinder is connected to the intermediate body to drive the intermediate body to move relative to the base. One end of the support arm is hinged to the intermediate body, and the other end is hinged to one end of the curved connecting rod. The middle bend of the curved connecting rod is hinged to the base through a hinge shaft, so that the curved connecting rod can rotate around the hinge point as the axis. The ends of the two curved connecting rods are respectively provided with a first tool and a second tool that can approach each other and partially overlap, and the first tool and the second tool have V-shaped cutting grooves that are opposite to each other.

[0012] In addition, the above embodiments of this utility model may also have the following additional technical features:

[0013] According to one embodiment of this utility model, the ends of the two bent connecting rods are respectively provided with a connecting block. A recessed semi-circular groove is formed in the middle of the end of the connecting block, and the center of the semi-circular groove is on the same straight line as the center of the V-shaped knife groove. When the two connecting blocks are joined together, their upper semi-circular grooves can be assembled into a complete circular hole, thereby wrapping the cut-off outer sheath and facilitating the separation of the outer sheath from the wire core.

[0014] According to one embodiment of this utility model, a stop shaft is provided on the base to block the movement of the intermediate body. This limits the stroke of the intermediate body, precisely controls the pushing distance of the cylinder component, and thus controls the rotation angle of the crankshaft, ensuring that the cutting depth of the tool only damages the outer sheath without damaging the wire core.

[0015] According to one embodiment of this utility model, the intermediate body is slidably connected to the base body via a first slider rail assembly. This not only prevents the intermediate body from shifting and maintains the synchronization accuracy of the two tools, but also reduces the frictional resistance of the reciprocating motion of the intermediate body, ensuring that the thrust of the cylinder is efficiently transmitted to the crank connecting rod.

[0016] According to one embodiment of this utility model, a side plate is provided on the base. The stripping structure is slidably disposed on one side of the side plate via a second slider rail assembly. The displacement assembly is disposed on the other side of the side plate and is used to drive the stripping structure to move relative to the side plate. After the outer sheath is cut, the stripping structure needs to be moved to drag the outer sheath off the wire core.

[0017] Based on the above technical solution, a passage opening is provided on the side plate. The displacement assembly includes a push-pull cylinder component disposed on the side plate. The telescopic end of the push-pull cylinder component is connected to the peeling structure via an adapter block, which can move within the passage opening. The displacement assembly has a simple structural design and can continuously push and pull the peeling structure relative to the side plate via the adapter block, adapting to continuous operation requirements.

[0018] According to one embodiment of this utility model, the wire fixing body includes a base, a wire platform, a clamping block, and a clamping cylinder disposed on the base. The clamping block is movably embedded in the middle of one side of the wire platform, and a wire resting portion is provided on each side of one side of the wire platform located outside the clamping block. The telescopic end of the clamping cylinder is connected to the clamping block to drive the clamping block closer to or further away from the inner wall of the wire platform. The wire is placed on the wire resting portions on both sides, and the clamping block presses the wire tightly from the middle, making the clamping action quick and convenient.

[0019] Based on the above technical solution, anti-slip ridges are provided on both sides of the inner wall of the clamping block. The anti-slip ridges increase friction and prevent the wire from being pulled off during stripping.

[0020] Furthermore, a receiving groove extending along its length is provided in the middle of the inner sidewall of the clamping block, and the receiving groove passes through the anti-slip ridges. This prevents the wire from sliding up and down during stripping.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. The V-shaped grooves of the dual blades form a complete circular cutting surface when they overlap, completing the circumferential cutting of the insulation layer in one go. This avoids the problem of traditional single-blade cutting, which requires rotating the wire or making multiple cuts, and significantly improves the peeling efficiency.

[0023] 2. The V-shaped blade groove design can be adapted to wires of different diameters. The cutting depth of the blade is controlled by a cylinder to avoid damaging the internal wire core.

[0024] 3. The mirror-symmetrical support arm combined with the crank linkage mechanism ensures synchronous movement of the two blades, uniform distribution of cutting force, and improves peeling accuracy and consistency. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] This utility model embodiment proposes a wire stripping device, which is mainly used to strip waste wires to recover the wire core. The structural design includes a base 1, a wire fixing body 2, and a stripping structure 3.

[0034] See Figure 1 As shown, the wire fixing body 2 is set on one side of the base 1, and the wire can be fixed on the wire fixing body 2 in a lateral posture, with one end of the wire exposed outward; the stripping structure 3 is set on the other side of the base 1, facing the wire fixing body 2 from left to right, and the stripping structure 3 can move closer to or further away from the wire fixing body 2 through a displacement component 4 (shown on the back of the diagram).

[0035] The peeling structure 3 includes a base 31, a cylinder component 32, an intermediate body 33, a pair of mirror-image support arms 34, and a pair of mirror-image curved connecting rods 35 mounted on the base 31. The peeling structure 3 is highly symmetrical, with the two support arms 34 being vertically symmetrical and the two curved connecting rods 35 being vertically symmetrical.

[0036] In practice:

[0037] The cylinder 32 is fixed to the base 31 in a lateral position, while the intermediate body 33 is slidably mounted on the base 31 via a first slider rail assembly 11. The telescopic end of the cylinder 32 is connected to the intermediate body 33, enabling the intermediate body 33 to perform linear reciprocating motion relative to the base 31. One end of the support arm 34 is hinged to the intermediate body 33, while the other end of the support arm 34 is hinged to one end of the crank-shaped connecting rod 35. The middle crank of the crank-shaped connecting rod 35 is hinged to the base via a hinge shaft 36. On 31, this allows the crank link 35 to rotate clockwise or counterclockwise around its central hinge point. In other words, when the cylinder 32 drives the intermediate body 33 to move left and right, the support arm 34 will also drive the crank link 35 to rotate accordingly, thereby achieving the clamping and separation of the two crank links 35. It should also be noted that the front length of the crank link 35 is longer than its rear length, as a force-saving lever design, to improve the flexibility when the ends of the two crank links approach each other.

[0038] The two bent connecting rods 35 are respectively equipped with a first cutter 37 and a second cutter 38 at their ends. When the ends of the two bent connecting rods 35 approach each other, the first cutter 37 and the second cutter 38 will also approach each other and partially overlap, thus achieving the cutting action. It should be noted that the first cutter 37 and the second cutter 38 have V-shaped grooves 371 that are opposite to each other. The tip of the V-shaped groove 371 is designed as a semi-circular shape. Thus, after the wire is sandwiched between the two V-shaped grooves 371, as the first cutter 37 and the second cutter 38 gradually overlap, the wire is finally squeezed into the tip of the V-shaped groove 371. Finally, the upper and lower V-shaped grooves achieve the cutting action of the wire sheath. That is, the V-shaped grooves of the two cutters form a complete circular cutting surface when they overlap, completing the circumferential cutting of the insulation layer in one go.

[0039] After the outer sheath of the wire is cut, the displacement component 4 drives the entire stripping structure 3 to move away from the wire fixing body 2, thereby pulling the cut outer sheath off the wire core and stripping the wire. The above process is then repeated.

[0040] See Figure 2 As shown, to avoid accidentally cutting the wire core during the stripping process, the overlapping movements of the first cutter 37 and the second cutter 38 need to be restricted. In this embodiment, the ends of the two bend-shaped connecting rods 35 are respectively provided with docking blocks 39. After the ends of the two bend-shaped connecting rods 35 approach each other, the two docking blocks 39 can abut against each other from top to bottom. A recessed semi-circular clamping groove 391 is formed in the middle of the end of the docking block 39, and the center of the semi-circular clamping groove 391 is on the same straight line as the center of the V-shaped cutter groove 371. After the two docking blocks 39 are combined, the semi-circular clamping grooves 391 on them can be assembled into a complete shape. The combined circular hole can clamp the outer sheath of the wire. When the semi-circular clamping groove 391 contacts the outer sheath of the wire, the V-shaped cutting groove 371 on the first cutter 37 / second cutter 38 also completes the cutting action of the outer sheath, thereby preventing the cutting edge from cutting further into the wire. After the outer sheath of the wire is cut off, the displacement component 4 drives the entire stripping structure 3 to move away from the wire fixing body. At this time, the semi-circular clamping groove 391 on the two connecting blocks 39 clamps the cut outer sheath to separate it from the wire core, and finally completes the stripping action.

[0041] See Figure 1 As shown, a stop shaft 6 is provided on the base 31 to block the forward movement of the intermediate body 33. The stop shaft 6 limits the maximum stroke of the intermediate body 33, precisely controls the pushing distance of the cylinder component, thereby controlling the rotation angle of the crank linkage, and ensuring that the cutting depth of the tool only damages the outer sheath without damaging the wire core.

[0042] See Figure 1 and Figure 3As shown, a side plate 5 is provided on the base 1 along its length. The seat of the stripping structure 3 is slidably set on one side of the side plate 5 via a second slider rail assembly 51, while the displacement assembly 4 is set on the other opposite side of the side plate 5 to drive the stripping structure 3 to move linearly relative to the side plate 5. When the stripping structure is close to the wire fixing body, it is convenient for the double cutter to "bite" the wire. When the stripping structure is far away from the wire fixing body, it is convenient for the double cutter to drag the cut outer sheath off the wire core.

[0043] A passageway 52 is provided on the side plate 5. The displacement assembly 4 includes a push-pull cylinder 41 mounted on the side plate 5. The telescopic end of the push-pull cylinder 41 is connected to the seat 31 of the peeling structure 3 via a transition block 42. The transition block 42 can move within the passageway 52. ​​The displacement assembly has a simple structural design and can continuously push and pull the peeling structure relative to the side plate via the transition block to reciprocate, adapting to continuous operation requirements.

[0044] Example 2

[0045] Based on the technical solution of Embodiment 1 above, this utility model embodiment improves the design of the wire fixing body.

[0046] See Figure 4 and Figure 5 As shown, the wire fixing body 2 includes a base 21, and a wire platform 22, a clamping block 24, and a clamping cylinder 25 disposed on the base 21. The clamping block 24 is movably embedded in the middle of one side of the wire platform 22, and a wire resting part 23 is provided on each side of the wire platform 22 outside the clamping block 24. The telescopic end of the clamping cylinder 25 is connected to the clamping block 24 to drive the clamping block 24 to move closer to or further away from the inner wall of the wire platform 22. The wire will be placed horizontally on the wire resting parts 23 on both sides, with one end of the wire exposed to one side of the wire platform towards the stripping structure 3. The clamping block 24 can press the wire from the middle. The clamping action is quick and convenient, realizing the rapid clamping of the wire.

[0047] To prevent the wire from slipping during subsequent stripping operations, anti-slip ridges 241 are provided on both sides of the inner wall of the clamping block 24, arranged in a sawtooth pattern. The anti-slip ridges increase the contact friction between the wire and the clamping block, preventing the wire from being pulled off during stripping.

[0048] Furthermore, the inner sidewall of the clamping block 24 is provided with a receiving channel 242 extending along its length. The receiving channel 242 passes through the anti-slip ridge group 241. When the clamping block approaches the inner wall of the wire platform, the wire placed on the wire rest can be just inserted into the receiving channel to prevent the wire from sliding up and down during stripping.

[0049] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
