DETAILED DESCRIPTION

[0058] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0059] Example 1:

[0060] In this embodiment, in order to solve the problem of slow efficiency in manual armored cable stripping, the utility model provides a stripping device that can be used for armored cable stripping. Of course, the stripping device can also be used for other types of cables and is not limited to armored cables.

[0061] like Figure 1-Figure 3 As shown, specifically, in this embodiment, the wire stripping device includes a housing 1 and a positioning module 2, a cross-cutting module 3, and a ring-cutting module 4 sequentially arranged in the housing 1; wherein:

[0062] The positioning module 2 is used to feed the cable to be stripped into the cross-cutting module 3 in a guided conveying manner. It should be noted that the guided conveying manner referred to here refers to guiding the cable to be stripped in the conveying direction so that it is aligned with the tangent position of the cross-cutting module 3 when entering the cross-cutting module 3, thereby axially cutting the outer protective sheath of the cable to be stripped.

[0063] The cross-cutting module 3 is used to perform axial cross-cutting of the outer protective sheath of the delivered cable to be stripped;

[0064] The circular cutting module 4 is used to perform radial circular cutting on the cable to be stripped that has completed axial cross-cutting.

[0065] The wire stripping device provided by the present invention locates the position of the cable to be stripped by means of a positioning module, thereby realizing guided transportation to ensure that the cable to be stripped is aligned with the cross-cutting module; the cross-cutting module is set to perform axial cutting of the protective layer of the cable, and then the circular cutting module is used to perform circumferential cutting on the protective layer that has been axially cut, so that the protective layer can be completely stripped off, realizing automatic wire stripping and solving the problem of low efficiency of manual wire stripping.

[0066] In order to realize automatic wire stripping, this embodiment further includes a power supply module 5 electrically connected to the cross-cutting module 3 and the ring-cutting module 4.

[0067] The power module 5 is used to supply power to the cross-cutting module 3 and the ring-cutting module 4, thereby realizing electrically controlled wire stripping.

[0068] The power module 5 may be an aluminum battery pack.

[0069] Example 2:

[0070] In this embodiment, the specific structure of the positioning module 2 is specifically limited.

[0071] like Figure 7 As shown, the positioning module 2 includes a first fixing plate 21, a second fixing plate 22, an upper pressing wheel 23, a lower pressing wheel 24, and a guide column 25; wherein:

[0072] The first fixing plate 21 and the second fixing plate 22 are both plate-shaped structures;

[0073] The first fixing plate 21 is fixed to the housing 1 and fixedly connected to one end of the guide post 25; by fixing the first fixing plate 21 to the housing 1, the position of one end of the guide post 25 can be fixed;

[0074] The second fixing plate 22 is disposed at the other end of the guide post 25;

[0075] Of course, in order to achieve a more stable supporting effect, in this embodiment, the number of guide pillars 25 is four, which are respectively provided at the four corners of the second fixing plate 22;

[0076] The upper pressing wheel 23 and the lower pressing wheel 24 are respectively fixed on the second fixed plate 22 and the first fixed plate 21 to form a wire portion therebetween; the cable to be stripped is fed into the cross-cutting module 3 through the wire portion; in order to ensure the smooth insertion of the cable to be stripped, there are two upper pressing wheels 23 and two lower pressing wheels 24, which are arranged in a one-to-one correspondence.

[0077] The above structure realizes the guided input of the cable to be stripped, ensuring that the cable to be stripped can face the cross-cutting module 3 to perform cross-cutting of the outer protective sheath, and ensuring that the cross-cutting depth on both sides is consistent.

[0078] Example 3:

[0079] In order to improve the applicability of the device so that cables with different wire diameters can be stripped, in this embodiment, the positioning module 2 also includes a first adjustment component arranged between the second fixed plate 22 and the end of the guide column 25, and the first adjustment component is used to provide a delivery pre-tightening force for the cable to be stripped.

[0080] like Figure 7 As shown, specifically, the first adjustment assembly includes an adjustment hole, a fastening bolt 26 and a first elastic member; wherein:

[0081] An adjustment hole is formed on the second fixing plate 22. To facilitate smooth axial movement of the second fixing plate 22 along the guide post 25, the diameter of the adjustment hole is slightly larger than the diameter of the guide post 25, so that the guide post 25 can be movably inserted into the adjustment hole, and the second fixing plate 22 can move axially relative to the guide post 25.

[0082] The end of the guide post 25 passes through the housing 1 and is screwed to the fastening bolt 26; this structure allows the other end of the guide post 25 to be fixed in position;

[0083] Since the second fixing plate 22 can move axially relative to the guide post 25, in order to ensure the pre-tightening force when the cable to be stripped is transported, in this embodiment, a first elastic member is sleeved on the guide post 25; the two ends of the first elastic member are respectively in contact with the second fixing plate 22 and the inner wall of the housing 1;

[0084] The second fixing plate 22 is pushed by the first elastic member. When the diameter of the cable to be stripped changes, the second fixing plate 22 can be pushed open. However, the elastic force of the first elastic member continuously provides a conveying pre-tightening force to ensure that the position of the conveying cable is stable and fixed.

[0085] In this embodiment, the first elastic member can be a first spring 27 . Of course, it can also be made of other elastic materials.

[0086] Example 4:

[0087] In order to further ensure the cable positioning effect and guiding accuracy, in this embodiment, a cable clamping groove 28 is provided on the opposite side of the upper pressing wheel 23 and the lower pressing wheel 24.

[0088] Specifically, the wire clamping groove 28 is an arc-shaped groove, and the depth should not be greater than the diameter of the cable to be stripped.

[0089] Example 5:

[0090] In this embodiment, the structure of the cross-cutting module 3 is specifically defined.

[0091] like Figure 1-Figure 4As shown, specifically, the cross-cutting module 3 includes an upper cross-cutting unit 31 and a lower cross-cutting unit 32 with identical structures; the upper cross-cutting unit 31 and the lower cross-cutting unit 32 are arranged opposite to each other to cross-cut the two sides of the cable to be stripped respectively.

[0092] Considering that the structures of the two cross-cutting units are exactly the same, the following structural description will take one side as an example.

[0093] In this embodiment, the upper cross-cutting unit 31 can be fixed to the housing 1, and the lower cross-cutting unit 32 is also fixed to the housing 1. The position of the two cross-cutting units is not adjustable, thereby adapting to a single specification of wire to be stripped. The cross-cutting module 3 of the above structure matches the positioning module 2 of Example 2, and both are only suitable for a single specification of wire to be stripped.

[0094] Example 6:

[0095] However, to expand the device's applicability, the positioning module 2 is improved in Example 3. A first adjustment component allows for adjustment of the conductor size within the positioning module 2, thereby accommodating the positioning and insertion of cables of varying sizes. Furthermore, to ensure that the cross-cutting module is also adaptable to a wide range of cable sizes, this embodiment also incorporates structural improvements to the cross-cutting module 3. Specifically, the cross-cutting module 3 includes a second adjustment component and a second elastic member. The second adjustment component adjusts the distance between the upper cross-cutting unit 31 and the lower cross-cutting unit 32, thereby adjusting the cross-cutting width and accommodating cross-cutting of cables of varying diameters. The second elastic member provides a cross-cutting preload between the upper cross-cutting unit 31 and the lower cross-cutting unit 32, ensuring that the two cross-cutting modules remain aligned with each other and are not susceptible to outward movement.

[0096] Specifically, the upper cross-cutting unit 31 is movably arranged on the housing 1 through the second adjustment component; the lower cross-cutting unit 32 is fixed on the housing 1; the second elastic member is respectively connected to the upper cross-cutting unit 31 and the lower cross-cutting unit 32 to provide cross-cutting pre-tightening force.

[0097] It should be noted here that the second elastic member can be made of the second spring 37. Of course, the second elastic member can also be made of other elastic materials.

[0098] Example 7:

[0099] like Figure 10 As shown, in this embodiment, the second adjustment component includes a rotating shaft 33, a buckle and an adjustment hole; wherein:

[0100] The adjustment holes are provided on the housing 1 and are located at the top and bottom of the rotating shaft 33;

[0101] The rotating shaft 33 is fixedly connected to the cross-cutting module 3, and both ends are rotatably inserted into the adjustment holes;

[0102] The buckle is detachably connected to the rotating shaft 33 , and can lock or release the position of the rotating shaft 33 .

[0103] When it is necessary to adjust the distance between the upper cross-cutting unit 31 and the lower cross-cutting unit 32 to adapt to cables to be stripped of different specifications, the buckle can be removed from the rotating shaft 33, and then the rotating shaft 33 can be rotated. By adjusting the angle of the rotating shaft 33, the angle adjustment of the upper cross-cutting unit 31 can be achieved, and the distance between the upper cross-cutting unit 31 and the lower cross-cutting unit 32 can be adjusted. It has a large stripping range and can strip cables of various wire diameters.

[0104] In this embodiment, the crosscutting module 3 includes a crosscutting drive source, a transmission mechanism 35, and a milling cutter assembly 36; wherein:

[0105] The cross-cutting drive source is connected to the milling cutter assembly 36 through the transmission mechanism 35, and can drive the milling cutter assembly 36 to rotate in the horizontal direction, thereby achieving axial cross-cutting of the outer protective sheath of the cable to be stripped.

[0106] In this embodiment, the cross-cutting drive source can be a motor 34. Of course, the cross-cutting drive source can also be other components that can drive the milling cutter assembly 36 to rotate, which is not specifically limited here.

[0107] The transmission mechanism 35 includes a driving gear 351, a belt 352, and a driven gear 353; the driving gear 351 is fixed to the output shaft of the motor 34, the driven gear 353 is fixed to the main shaft 363, and the two ends of the belt 352 are respectively sleeved on the driving gear 351 and the driven gear 353.

[0108] like Figure 5 and Figure 6 As shown, in this embodiment, the milling cutter assembly 36 includes a limiting ring 361, a milling cutter 362, and a spindle 363; wherein:

[0109] The main shaft 363 is connected to the transmission mechanism 35 and can rotate under the drive of the transmission mechanism 35;

[0110] The milling cutter 362 is fixed on the spindle 363;

[0111] There are two limiting rings 361, which are fixed on the main shaft 363 on both sides of the milling cutter 362 respectively;

[0112] A gap is left between the circumferential surface of the limiting ring 361 and the end surface of the milling cutter 362 .

[0113] It should be noted here that the interval is the stripping depth of the cable to be stripped.

[0114] In order to improve the application range of the wire stripping device and to adjust the wire stripping depth, in this embodiment, Figure 9As shown, the limiting ring 361 includes an inner ring 3611 and an outer ring 3612 that is detachably arranged on the outside of the inner ring 3611 .

[0115] Furthermore, the inner ring 3611 is an integrated structure. The inner ring 3611 located on one side of the milling cutter 362 is fixed to the main shaft 363 through at least one bearing 364, and the milling cutter 362 is fixed on the main shaft 363. One end of the inner ring 3611 located on the other side of the milling cutter 362 is fixed to the main shaft 363 through a gasket 365, a fastening nut 366, a nut ring 367 and a large bearing 368, and the other end is fixed to the other end of the main shaft 363 through a bearing 364.

[0116] Considering that the outer sheath of the cable to be stripped is in contact with the retaining ring 361 when it enters the cross-cutting module 3, adjusting the diameter of the retaining ring 361 also adjusts the cross-cutting depth. To achieve different stripping depths, in this embodiment, at least one outer ring 3612 is provided, each with different specifications. Outer rings 3612 of different specifications can be installed based on the actual diameter of the cable to be stripped.

[0117] In order to facilitate the replacement of the outer ring 3612, in this embodiment, the outer ring 3612 is a split structure, which is composed of two semicircular outer rings. Each semicircular outer ring is tightened on the inner ring 3611 by bolts, thereby achieving the replacement and fixation of the outer ring 3612.

[0118] Example 8:

[0119] In this embodiment, the structure of the ring cutting module is specifically defined.

[0120] like Figure 8 As shown, specifically, the circular cutting module 4 includes a rotating knife cylinder 41 and a rotating knife 42; wherein:

[0121] The rotary knife drum 41 is a cylindrical structure and is rotatably arranged on the housing 1; and the inner cavity of the rotary knife drum 41 faces the middle position of the two cross-cutting units, that is, the output position of the cables to be stripped.

[0122] The rotary knives 42 are evenly arranged along the circumference of the rotating knife cylinder 41 .

[0123] When the knife cylinder 41 is rotated, the rotary knife 42 therein can be used to perform radial circular cutting on the outer protective sheath of the cable to be stripped.

[0124] When the above structure is adopted, the protective sheath of the cable can be cut by manually rotating the rotary knife drum 41 .

[0125] Of course, in order to further achieve the automatic tangent effect, in this embodiment, a rotation drive source can also be set in the circular cutting module 4, and the rotation drive source is connected to the rotating knife cylinder 41 in a transmission manner. The rotation drive source can be used to drive the rotating knife cylinder 41, thereby achieving automatic circular cutting.

[0126] The rotation driving source may also be made of a motor, and the rotation of the rotary knife cylinder 41 may be electrically driven through a transmission structure.

[0127] The wire stripping device of the utility model has a small size, a simple structure, is easy to carry, realizes the miniaturized design of the wire stripping device, is more convenient to use, and solves the problem of bulky wire stripping of large equipment.

[0128] Furthermore, in order to achieve automatic control, the wire stripping device of the present invention also includes a single chip microcomputer, which is electrically connected to the power module 5, the cross-cutting module 3 and the ring-cutting module 4, and the motor is controlled by the single chip microcomputer to strip the cable.

[0129] The wire stripping device of the utility model is controlled by a single chip microcomputer, thereby solving the problem of high cost caused by using a PLC.

[0130] Directions:

[0131] When the wire stripping device of the present invention strips the armored cable, the stripping process is as follows:

[0132] First, the upper cross-cutting unit 31 in the cross-cutting module 3 adopts a rocker design, with the rotation axis 33 as the rotation axis. According to the wire diameter of the armored cable, the upper cross-cutting unit 31 is rotated around the rotation axis 33 to adapt to different cable diameters. After the adjustment is completed;

[0133] The armored cable is fed into the positioning module 2 at a certain speed. The upper pressing wheel 23 on the second fixing plate 22 is stretched by the armored cable, and the upper pressing wheel 23 drives the second fixing plate 22 upward. The guide pillar 25 is compressed by the second fixing plate 22, and the armored cable is thus tightly pressed by the positioning module 2. At this time, the axial feeding action of the armored cable is completed manually.

[0134] Turn on the power module 5 switch, the power is turned on, and the motor 34 starts to work. The motor 34 drives the driving gear 351 to rotate, and then drives the driven gear 353 to rotate through the belt 352. The driven gear 353 is connected to the main shaft 363, thereby driving the milling cutter 362 to directly cut the cable protective layer horizontally. One side of the milling cutter 362 is close to the limit ring 361, and the other side is fastened by the fastening nut 366, so that it rotates synchronously with the main shaft 363.

[0135] When the armored cable enters the cross-cutting module 3 through the positioning module 2, the relatively arranged cross-cutting units are tightly fitted on the armored cable under the action of the second spring, and the high-speed rotating milling cutter 362 mills off the protective layer of the armored cable.

[0136] Since the cross-cutting module includes two units that are arranged opposite to each other, the protective layers on both sides of the armored cable can be cross-cut simultaneously; the lower cross-cutting unit 32 is fixed on the casing 1, and the upper cross-cutting unit 31 can rotate. It adopts a rocker design and can rotate with a rotating shaft 33. The rotating shaft 33 is rotated manually. When it is rotated to the appropriate position, the rocker rotating shaft 33 is fixed with a limit buckle, thereby achieving position locking of the upper cross-cutting unit 31.

[0137] When the armored cable moves to the ring cutting module 4, the rotary knife cylinder 41 is rotated to drive the rotary knife 42 to ring cut the protective layer of the armored cable.

[0138] When the stripping depth needs to be adjusted, the limit ring consists of an inner ring and an outer ring. The outer ring can be replaced and fixed to the inner ring by two screws. The stripping depth can be adjusted by changing the diameter of the outer ring.
