Description

Technical Field

[0001] The invention relates to the field of cable manufacturing, and in particular to a cable stripping device. Background Art

[0002] At present, during the production of special cables, production errors may occur in the insulation process, and unstable raw materials may cause the finished product to be unqualified, but the internal cable is not damaged and can continue to be used. To reduce losses, the outer skin can be peeled off and continued to be used.

[0003] At present, the means of handling discarded cables are to extract the inner cable, or to cut the outer skin longitudinally to remove the inner cable; the direct extraction method can remove the inner cable without damaging the inner cable, but when encountering a long cable, extraction becomes very laborious. Although it is possible to perform segmented circular cutting, the circular cutting process is more complicated and the investment cost will be greater; although longitudinal cutting of the outer skin for extraction can adapt to cables of various lengths, it may damage the inner cable during cutting, making the originally intact internal cable become unqualified, and the existing cutting machines rarely have automatic stripping devices. After cutting the outer skin, some cables with harder outer skins still need to be manually removed from the outer cable, so it is necessary to design a device that can automatically strip the outer skin and separate the internal cable from the outer skin. Summary of the invention

[0004] One of the purposes of the present invention is to solve the problem in the prior art that unqualified cables cannot be effectively disassembled and recycled, resulting in waste of resources.

[0005] One of the purposes of the present invention is to provide a method for stripping a substandard cable.

[0006] To achieve one of the above purposes, the present invention adopts the following scheme: a wire stripping device, characterized in that it includes: a support part, an adjustment part, a cutting part, a mold part, a driving part, and a control part.

[0007] The support part is an inverted T-shaped frame, a mounting plate is arranged above the frame, and the mounting plate is provided with mounting holes and mounting grooves.

[0008] The adjustment part is composed of two guide wheels, which are arranged on the mounting plate. The upper guide wheel cooperates with the lower guide wheel. The upper guide wheel and the lower guide wheel are provided with adjustment knobs to adjust the position.

[0009] The cutting part is arranged on the mounting plate, and is located on the right side of the adjusting part. The cutting part is composed of a saw blade and a cable guide wheel. The saw blade is arranged above the cable guide wheel. The cable guide wheel is provided with an adjusting knob to adjust the position. The slider is arranged between the cable guide wheel and the mounting plate. The slider is installed in the slide groove of the mounting plate. A sliding rod is also arranged under the slider. A guide ring is also arranged on the sliding rod. The guide ring is fixedly connected to the lower end of the mounting plate.

[0010] The mold part is arranged on the right side of the cutting part, and the mold part comprises a mold, a mold fixing block, and a protective cover; the mold is arranged between the saw blade and the cable guide wheel; the mold fixing block is arranged on the mounting plate, and the mold is installed below the mold fixing block.

[0011] The driving part is a motor, and the motor is connected to the saw blade in a power connection.

[0012] A control part is provided on the frame, and controls the driving part.

[0013] To achieve the second objective, the present invention adopts the following technical solution: a cable stripping method, comprising the following steps:

[0014] Adjust the upper guide wheel, lower guide wheel and guide wheel to a gap suitable for the cable to enter, pass the cable between the upper guide wheel and the lower guide wheel, and the cable reaches the wire pulley.

[0015] The control part controls the motor, the motor drives the saw blade, the saw blade cuts the outer skin of the cable, the cable continues to move, the outer skin contacts the mold, and the internal cable continues to move.

[0016] The notch of the outer skin contacts the mold, and the mold stretches the outer skin to a position larger than the diameter of the internal cable. The outer skin and the internal cable sag due to gravity and are separated. The separated outer skin and internal cable are recycled.

[0017] The mold also includes a replaceable part. The mold uses molds with different mold opening sizes according to different wire diameters. The original mold is removed by removing the screws of the mold mounting hole, and the mold that matches the wire diameter is replaced and then fixed with screws.

[0018] The present invention utilizes a saw blade to cut the outer skin of the discarded cable, and a mold enters the gap between the outer skin and the internal cable, so that the mold stretches the cut of the outer skin. The width of the mold gradually changes so that the mold can stretch the outer skin to exceed the diameter of the internal cable. After reaching the maximum stretching distance, the outer skin has been separated from the internal cable, and the outer skin automatically droops and separates due to gravity. Subsequent transportation can enable continuous cutting and peeling, thereby realizing the recycling of unqualified cables and effectively solving the problem of waste of resources caused by the inconvenience of disassembling and recycling unqualified cables.

[0046] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0048] Embodiment 1:

[0049] The embodiment of the present application provides a cable stripping device, characterized in that it includes: a support part, an adjustment part, a cutting part, a mold part, a driving part, and a control part;

[0050] Specifically, if Figure 1 The figure shows the front layout of the cable stripping device.

[0051] like Figure 2 The figure shows a top view of the cable stripping device, in which the shaft of the motor is connected to the saw blade, and the motor is mounted on the back of the mounting plate and controlled by the control part.

[0052] like Figure 3 The figure shows a left view of the cable stripping device. The upper and lower adjustment knobs adjust the vertical positions of the upper and lower guide wheels to accommodate cables of different thicknesses.

[0053] like Figure 4 The figure shows a schematic diagram of the mounting plate area of ​​the cable stripping device. The unqualified cable passes between the upper guide wheel and the lower guide wheel. The upper guide wheel and the lower guide wheel are adjusted to appropriate positions so that the cable can be stably transmitted from the middle to the cutting part; the cable guide wheel adjusts its position according to the wire diameter of the cable to ensure that the saw blade will not cut the internal cable during cutting; the mold is installed on the mold fixing block on the mounting plate, and the upper surface of the mold is as close to the bottom cutting position of the saw blade as possible while ensuring normal operation.

[0054] like Figure 5As shown, it is a three-dimensional diagram of the mold. The top of the mold is a plane with two through holes on it. It is fixed to the mold mounting block by screws passing through the through holes. The smallest front end of the mold is the mold opening, which becomes larger as it goes back, presenting a cone-like shape.

[0055] Embodiment 2:

[0056] like Figure 6 As shown, this is the main view of the mold. The front end of the mold presents an inversely proportional curve from front to back, so that the mold at the slightly front end can be fully inserted into the outer skin, and the outer skin can be completely stretched out at a later point. Because the outer skin and the internal cable have different softness levels, the outer skin sags more after the mold is stretched, thereby achieving a separation effect; the back half of the mold presents an inverted trapezoid.

[0057] like Figure 7 As shown, it is a top view of the mold, with a mold groove at the bottom. When peeling, the internal cable passes through the mold groove. The mold groove gradually expands from the front end to the rear end, which can reduce the scratches between the mold and the cable. The front end of the mold from bottom to top is shuttle-shaped, and the thinnest edge formed by the mold groove can be more easily inserted into the gap between the outer skin and the internal cable. The curve of the middle part is relatively gentle, which can allow the mold to fully enter the outer skin.

[0058] like Fig.10 As shown, it is the grinding part, which is located between the adjusting part and the cutting part, and is composed of a guide rail and a grinding wheel. The guide rail is fixedly connected to the slider, and the cross-section of the guide rail is the same shape and height as the cross-section of the cable guide wheel. The rotating shaft of the grinding wheel is connected to the rotating shaft of the motor through a conveyor belt. The grinding wheel is responsible for grinding a plane on the top of the outer skin of the unqualified cable to prevent it from bouncing off due to the arc and material of the outer skin when the saw blade is cutting. After grinding, the upper plane can make the saw blade better exert force and directly cut the outer skin.

[0059] The remaining features are the same as those of the first embodiment.

[0060] Embodiment three:

[0061] like Figure 8 , 9 As shown, a cable stripping method comprises the following steps:

[0062] Adjust the upper guide wheel, lower guide wheel and guide wheel to a gap suitable for the cable to enter, pass the cable between the upper guide wheel and the lower guide wheel, and the cable reaches the wire pulley.

[0063] The control part controls the motor, the motor drives the saw blade, the saw blade cuts the outer skin of the cable, the cable continues to move, the outer skin contacts the mold, and the internal cable continues to move.

[0064] The notch of the outer skin is in contact with the mold, and the mold stretches the outer skin to a position larger than the diameter of the internal cable. The outer skin and the internal cable sag due to gravity and are separated. The separated outer skin and internal cable are recycled.

[0065] The mold also includes a replaceable part. The mold uses molds with different mold opening sizes according to different wire diameters. The original mold is removed by removing the screws of the mold mounting hole, and the mold that matches the wire diameter is replaced and then fixed with screws.

[0066] like Fig.10 , 11 As shown, the cable comes out from between the upper guide wheel and the lower guide wheel and enters the guide rail. The cable on the guide rail is ground by the grinding wheel above, so that a segment plane is formed at the upper end of the outer skin. Then the cable enters the cutting part and reaches the cable guide wheel. The saw blade cuts the plane at the upper end of the outer skin.

[0067] Although the above describes the illustrative specific embodiments of the present invention so that those skilled in the art can understand the present invention, the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, all inventions and creations using the concepts of the present invention are protected.
