Description

Technical Field

[0001] This utility model relates to the field of wire and cable production technology, and in particular to a cable outer layer stripping device. Background Technology

[0002] During cable production, numerous processes are involved, and defects may occur in the outer layer. Discarding the entire cable would be a significant waste of resources. Therefore, if only the outer layer of a cable is defective, the outer layer is separated from the inner core, and the inner core is recycled for rework.

[0003] Publication No. CN 211958585 U discloses a novel cable stripping device. The device uses an adjustable component to flexibly adjust the clamping block, facilitating the adjustment of the distance between two semi-circular through slots to accommodate cables of different sizes. However, this design does not provide proper cable guidance. The cable vibrates during its movement relative to the stripping device, causing the cable core to come into contact with the stripping blade, resulting in damage to the core and making it unrecoverable.

[0004] Therefore, a cable outer layer stripping device is proposed to solve the technical problem that existing equipment fails to guide the cable during the stripping process, resulting in damage to the cable core, so as to ensure that the cable is properly treated. Utility Model Content

[0026] The technical solution was explained in detail. In the existing solution, the cable was not properly guided, causing it to vibrate during movement relative to the stripping equipment. This resulted in the cable core coming into contact with the stripping blade, damaging the core and making it unrecoverable. For example... Figure 1 As shown, this utility model provides a cable outer layer stripping device, comprising: Base 1; The conductor ring 2 is located at one end of the base 1 and is used to guide the movement of the cable 100; The sheath-piercing assembly 3 is set on the base 1 and located on the discharge side of the wire ring 2. It is coaxially arranged with the wire ring 2 and is used to pierce the outer sheath 110 of the cable 100 from two opposite directions. The wire stripping assembly 4 is mounted on the base 1, located on the discharge side of the stripping assembly 3, and coaxially mounted with the wire ring 2. It is used to strip the outer sheath 110 and inner core 120 of the cable 100 after it has been punctured by the stripping assembly 3.

[0027] A wire ring 2 is provided before the stripping assembly 3. The guide ring 2 guides the cable 100 into the stripping assembly 3, which can reduce the vibration of the cable 100 during the movement, ensure that the stripping assembly 3 will only puncture the outer sheath 110 of the cable 100, ensure the integrity of the inner core 120 of the cable, and improve the yield of the inner core 120 after the cable 100 is stripped.

[0028] like Figure 1 and Figure 2 As shown, in order to prevent the cable 100 from shaking during movement, the conductor ring 2 forms a guide cavity 201, which is coaxially arranged with the cable 100 and conforms to the contour of the cable 100. The stripping assembly 4 is provided with a separation cavity 401, which is coaxially arranged with the cable 100 and conforms to the contour of the inner core 120 of the cable 100.

[0029] The wire ring 2 and the stripping assembly 4 form a guide cavity 201 and a separation cavity 401 arranged coaxially. The guide cavity 201 and the separation cavity 401 are adapted to the outer contour of the cable 100 and the outer contour of the inner core 120, so that the cable 100 will not shake when it moves around the stripping assembly 3, so as to achieve the purpose of the stripping assembly 3 only piercing the outer sheath.

[0030] like Figure 2 As shown, in order to effectively separate the outer sheath 110 and the inner core 120, the wire stripping assembly 4 includes: A stripping ring 41 is disposed at the end of the base 1 away from the conductor ring 2 and is coaxially disposed with the conductor ring 2. The stripping ring 41 is hollow inside and forms a separation cavity 401. At least two separation components 42 are rotatably mounted on the base 1 and symmetrically distributed on both sides of the stripping ring 41 along the radial extension direction of the cable 100 to guide the movement of the outer sheath 110.

[0031] After the outer sheath 110 of the cable 100 is pierced by the stripping component 3, the inner core 120 enters the separation cavity 401 formed by the stripping ring 41. Under the action of the stripping ring 41, the outer sheath 120 is separated from the inner core 120, and the outer sheath 120 will be guided by at least two separation components 42 to separate the movement of the outer sheath 120 and the inner core 120, so as to avoid the outer sheath 120 from getting tangled on the inner core 120.

[0032] like Figure 1 and Figure 2 As shown, in order to reduce the resistance of the outer skin 110 during movement, at least two separation components 42 each include: The first separating wheel 421 and the second separating wheel 422 are rotatably mounted on the base 1 and are spaced apart along the direction of movement of the cable 100, and the gap is adapted to the contour of the stripped outer sheath 110.

[0033] Specifically, there are two separation components 42. The gap formed in each separation component 42 is adapted to the contour of the peeled outer skin 110. Under the action of the skin-breaking component 3, the outer skin 110 is divided into two semi-circular rings. Correspondingly, the first separation wheel 421 has an arc-shaped concave surface, and the second separation wheel 422 has an arc-shaped protrusion, thereby forming a semi-circular gap, so that the outer skin 110 can simultaneously conform to the two first separation wheels 421 and the second separation wheel 422 for movement.

[0034] like Figure 1 As shown, the sheath-piercing assembly 3 pierces the outer sheath 110 from both the top and bottom sides of the cable 100. The sheath-piercing assembly 3 includes: The first sheath-piercing component 31 is disposed on the base 1 and located on the discharge side of the wire ring 2, for piercing the outer sheath 110 from one side of the cable 100; The second skin-piercing component 32 is disposed on the base 1 and located on the discharge side of the first skin-piercing component 31, and is used to pierce the outer skin 110 from the side opposite to the first skin-piercing component 31.

[0035] The first piercing component 31 and the second piercing component 32 are spaced apart on the base 1 and pierce the outer sheath 110 in different areas. In this way, the contact between the inner core 120 and the first piercing component 31 or the second piercing component 32 caused by the vibration of the cable 100 can be reduced.

[0036] like Figure 3 As shown, the first piercing component 31 pierces the outer sheath 110 from above the cable 100. The first piercing component 31 includes: The first fixing frame 311 is vertically set on the base 1 and located on the discharge side of the guide ring 2; The first skin-breaking component 312 is located at the end of the first fixing frame 311 away from the base 1, and one end is inserted into the outer skin 110; The first receiving wheel 313 is rotatably mounted on the first fixed frame 311, located directly below the first sheathing piece 312, and is used to receive the cable 100.

[0037] Specifically, the first sheathing component 312 is configured as a sheathing needle. The cable 100 passes through the first receiving wheel 313. The sheathing needle is located above the cable 100, and its tip pierces the outer sheath 110. When the cable 100 moves relative to the base 1, one side of the outer sheath 110 of the cable 100 will be cut by the sheathing needle, thereby completing one sheathing process of the cable 100.

[0038] like Figure 3 As shown, in order to ensure proper peeling 110, the position of the first peeling component 312 relative to the first fixing frame 311 is adjustable.

[0039] Specifically, the piercing needle is mounted on the first fixing bracket 311 via a locking clamp. The locking clamp forms an adjustable cavity in the vertical direction, which conforms to the outer contour of the piercing needle. A bolt is provided on the locking clamp to adjust the size of the cavity, thereby loosening or fixing the piercing needle. When it is necessary to adjust the height of the piercing needle, the bolt is loosened to adjust the height of the piercing needle relative to the base 1, and then the bolt is tightened to fix the piercing needle.

[0040] like Figure 4 and Figure 5 As shown, the second piercing component 32 pierces the outer sheath 110 from below the cable 100. The second piercing component 32 includes: The second fixing frame 321 is vertically mounted on the base 1 and located on the discharge side of the first skin-breaking component 31; The second receiving wheel 322 is disposed at the end of the second fixing frame 321 away from the base 1, and is used to hold the cable 100 from the direction opposite to the first receiving wheel 313; The second leather-breaking component 323 is mounted on the second fixing frame 321 and located directly below the receiving wheel 322, with one end piercing into the outer skin 110.

[0041] Specifically, the second puncturing component 323 is configured as a puncturing wheel. Under the clamping of the second receiving wheel 322 and the puncturing wheel, the cable 100 will be punctured again when passing through the puncturing wheel, thus completing the secondary puncture of the cable 100. Furthermore, the puncturing needle and the puncturing wheel are set in different positions, which can effectively prevent damage to the inner core 120.

[0042] like Figure 5 As shown, in order to effectively guide the movement of the cable 100, both the first receiving wheel 313 and the second receiving wheel 322 are provided with annular grooves 301, which are adapted to the contour of the cable 100.

[0043] Both the first receiving wheel 313 and the second receiving wheel 322 are provided with annular grooves 301. The annular grooves 301 can effectively limit the cable 100 from deviating in its own radial direction, ensuring that the piercing needle and the piercing wheel can stably pierce the outer sheath.

[0044] like Figure 4 As shown, to ensure effective secondary skin breaking by the second skin breaking component 32, the second skin breaking component 32 further includes: An elastic member 324 is disposed between the second receiving wheel 322 and the second fixing frame 321 to elastically support the second receiving wheel 322 against the cable 100.

[0045] Specifically, the elastic component 324 includes a spring 3241 and a connecting rod 3242. The connecting rod 3242 has a vertical end and a horizontal end that are orthogonally connected to each other. A through hole is provided on the fixing frame 321. The vertical end of the connecting rod 3242 passes through the through hole and the spring 3241 from the top of the fixing frame 321 and is connected to the second receiving wheel 322. The horizontal end of the connecting rod 3242 is located above the through hole. When the cable 100 is located between the second receiving wheel 322 and the puncturing wheel, the spring 3241 is in a compressed state, and the spring 3241 makes the second receiving wheel 322 elastically resist the cable 100.

[0046] More specifically, after the cable 100 is initially damaged by the first sheath-breaking component 312, if the first sheath-breaking component 312 only slightly scratches the outer sheath 110 and the outer sheath 110 is not completely detached, the second receiving wheel 322, under its own weight and the elastic support of the spring 3241, can stably cut open the outer sheath 110; if the first sheath-breaking component 312 deeply scratches the outer sheath 110, the outer sheath 110 may completely rupture. When the cable 100 is located in the second... When the sheath is broken at position 32, the inner core 120 of the cable 100 contacts the second receiving wheel 322, while the outer sheath 120 of the cable 100 contacts the second sheath breaking component 323. Under the elastic push of the spring 3241, it can still be ensured that there is an elastic resistance between the outer sheath 120 of the cable 100 and the second sheath breaking component 323, ensuring that the second sheath breaking component 323 effectively breaks the outer sheath 120, thereby ensuring that the outer sheath 120 is stably separated under the action of the subsequent stripping ring 41.

[0047] The working principle of this cable outer layer stripping device is as follows: the conductor ring 2 and the stripping assembly 4 form a coaxially arranged guide cavity 201 and separation cavity 401, and the guide cavity 201 and separation cavity 401 are adapted to the outer contour of the cable 100 and the outer contour of the inner core 120, so that the cable 100 will not shake when it moves around the stripping assembly 3. In addition, the first stripping component 31 and the second stripping component 32 are arranged at intervals on the base 1, and the outer sheath 110 is pierced in sections. In this way, the contact between the inner core 120 and the first stripping component 31 and the second stripping component 32 caused by the shaking of the cable 100 can also be reduced.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
