Technical Field

[0001] This invention relates to the field of wire stripping machine technology, specifically to a cable stripping knife holder structure with adjustable tension for easy cleaning. Background Technology

[0002] The wire stripper mainly consists of two structural parts: the blade holder structure and the wire take-up and undo mechanism. It also includes an electrical control system to control the operation of the blade holder mechanism and the wire take-up and undo mechanism.

[0003] Traditional blade holders have a single-blade movement with a large stroke. Due to the different wire materials, some wires have a shielding layer made of metal mesh. Traditional blade holders do not have a tension adjustment mechanism, and the clamping force of the two blades is fixed. This makes it easy to damage the shielding layer when the blade hits it, and the debris generated from stripping the wire cannot be automatically cleaned up.

[0004] Therefore, there is an urgent need to design a cable stripper holder structure with adjustable tension and easy cleaning to solve the above problems. Summary of the Invention

The active component is linked to the two tool holders through the relative motion component, and the active component is linked to the cleaning roller through the transmission component. The active component consists of a spindle and a motor. The motor is fixed inside the housing, and the output end of the motor is connected to the spindle via a coupling. The relative motion component consists of a linkage component and a drive gear. The drive gear is sleeved on the spindle. There are two linkage components, which are respectively mounted on two tool holders. The transmission assembly consists of a support frame, a connecting shaft, a synchronizing element, a driving bevel gear, and a driven bevel gear. One end of the support frame is fixed to the blade holder adjacent to the cleaning roller, and the other end of the support frame is rotatably connected to the driving bevel gear via a rotating shaft. The synchronizing element consists of two synchronous pulleys and a synchronous belt. One synchronous pulley is fixed to the main shaft, and the other synchronous pulley is coaxially connected to the driving bevel gear. The two ends of the synchronous belt are respectively sleeved on the two synchronous pulleys. The driven bevel gear is fixed to the end of the connecting shaft, and the driven bevel gear meshes with the driving bevel gear. The connecting shaft passes through the housing and is slidably connected to the housing.

[0007] Preferably, the linkage assembly includes a slide rod, a fixed tooth, a movable tooth, a torsion spring, and a limiting block. The two slide rods are respectively fixedly connected to two tool holders. Fixed teeth are evenly distributed at one end of the slide rod, and movable teeth are evenly distributed at the other end of the slide rod. The fixed teeth and movable teeth are equidistantly arranged. The movable teeth are rotatably connected to the slide rod via a rotating shaft. The torsion spring is coaxially connected to the movable teeth. The two ends of the torsion spring are respectively fixedly connected to the movable teeth and the slide rod. The fixed teeth are located on the side of the movable teeth away from the fixed teeth. The limiting block is distributed adjacent to the movable teeth and is fixedly connected to the slide rod. The fixed teeth mesh with the drive gear.

[0011] (1) By cooperating with the active component and the relative motion component to drive the two tool holders to move relative to each other, the single-tool transmission process is changed to a double-tool process, which shortens the process time of tool retraction and release and improves the efficiency of tool retraction and release.

[0012] (2) By installing one of the blades on the connecting rod, when the blade is subjected to resistance greater than the spring force, the connecting rod will retract into the cylinder, which avoids the blade from scratching the shielding layer due to excessive force when it hits the shielding layer. Furthermore, by rotating the screw, the top plate can be pushed to compress the spring, increasing the amount of spring force applied to the connecting rod, thereby controlling the force of retracting and releasing the blade.

[0013] (3) By assembling a cleaning roller on the blade holder and cooperating with the drive assembly and transmission assembly to drive the cleaning roller to rotate, the debris generated during stripping is cleaned. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-8 An embodiment of the present invention provides a cable stripper holder structure with adjustable tension for easy cleaning, comprising a housing (1), on which two blade holders (2) are movably mounted, the two blade holders (2) being distributed opposite to each other, and each blade holder (2) being equipped with a blade (5). The first blade (5) is fixedly connected to the blade holder (2) by screws, and the other blade (5) is equipped with a tension adjustment mechanism (6) and connected to the blade holder (2) through the tension adjustment mechanism (6). The tension adjustment mechanism (6) includes a cylinder (61), on which a connecting block is fixedly fixed on the upper surface and fixedly connected to the blade holder (2) through the connecting block. One end of the cylinder (61) is telescopically connected to a connecting rod (62), and the other end of the cylinder (61) is threadedly connected to a connecting rod (62). A screw (65) is rotatably connected to a top plate (64) at one end inside the cylinder (61). A spring (63) abuts against the end of the top plate (64) near the connecting rod (62). The end of the spring (63) away from the top plate (64) abuts against the connecting rod (62). The end of the connecting rod (62) away from the spring (63) is fixedly connected to one of the blades (5). Thus, when the resistance of the blade (5) mounted on the connecting rod (62) is greater than the elastic force of the spring (63), the connecting rod (62) will retract into the cylinder (61). By rotating the screw (65) to push the top plate (64) to extend and retract within the cylinder (61), the squeezing force on the spring (63) can be adjusted, thereby adjusting the squeezing force of the spring (63) on the connecting rod (62) and controlling the retraction resistance of the blade (5).

[0018] It is worth mentioning that a handwheel is fixed on the screw (65), which makes it convenient for the user to hold and control the rotation of the screw (65).

[0019] Considering the need to clean the stripped wire, a cleaning roller (7) is mounted on one of the cutter holders (2) adjacent to the tension adjustment mechanism (6).

[0020] Furthermore, the housing (1) is equipped with a drive mechanism for the drive tool holder (2) and the cleaning roller (7). The drive mechanism consists of an active component, a relative motion component and a transmission component. The active component is connected to the two tool holders (2) through the relative motion component, and the active component is connected to the cleaning roller (7) through the transmission component. By driving the relative motion component and the transmission component through the drive component, the movement of the tool holder (2) and the cleaning roller (7) can be controlled.

[0021] Furthermore, such as Figure 3 and Figure 6 As shown, the active component consists of a spindle (10) and a motor (19). The motor (19) is fixed inside the housing (1). The output end of the motor (19) is connected to the spindle (10) via a coupling. The motor (19) can drive the spindle (10) to rotate.

[0022] Furthermore, such as Figure 3 and Figure 7As shown, in order to ensure that the drive assembly no longer acts on the relative motion component after driving the relative motion component into position, but only acts on the transmission component, the relative motion component is composed of a linkage component (3) and a drive gear (11). The drive gear (11) is sleeved on the spindle (10). There are two linkage components (3), which are respectively installed on two tool holders (2). The linkage component (3) includes a slide rod (31), a fixed gear (32), and a movable gear (33). The slide rods (31) are fixedly connected to the two tool holders (2), and the slide rods (32) are equipped with a movable tooth (33), a torsion spring (34), and a limiting block (35). The two slide rods (31) are fixedly connected to the two tool holders (2). Fixed teeth (32) are evenly distributed at one end of the slide rods (31), and movable teeth (33) are evenly distributed at the other end of the slide rods (31). The fixed teeth (32) and movable teeth (33) are equidistantly arranged. The movable teeth (33) are rotatably connected to the slide rods (31) through a rotating shaft. The torsion spring (34) is coaxial with the movable teeth (33). The torsion spring (34) is fixedly connected to the movable tooth (33) and the slide rod (31) at both ends, respectively. The fixed tooth (32) is located on the side of the movable tooth (33) away from the fixed tooth (32). The limiting block (35) is distributed adjacent to the movable tooth (33) and is fixedly connected to the slide rod (31). The fixed tooth (32) meshes with the driving gear (11). When the driving gear (11) rotates clockwise, it pushes the fixed tooth (32) until the driving gear... (11) When engaged with the movable tooth (33), the two blades (5) are just in the closed state. At this time, the motor (19) does not stop working, and the drive gear (11) continues to rotate, which pushes the movable tooth (33) to rotate counterclockwise, but does not act on the slide bar (31), so it does not act on the relative motion component, but only acts on the transmission component. When the drive gear (11) changes to rotating counterclockwise, since the movable tooth (33) is limited by the limit block (35), it does not affect the back motion of the linkage component (3).

[0023] It is worth mentioning that the above description is based on the instruction manual attached. Figure 3 Based on the linkage component (3) on the right side, the linkage component (3) on the left side is exactly opposite to the direction of motion described above.

[0024] Furthermore, such as Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, in order for the motor (19) to drive the bidirectional motion component and at the same time drive the cleaning roller (7) to rotate, a transmission component is designed. The transmission component consists of a support frame (4), a connecting shaft (9), a synchronizing element (12), a driving bevel gear (13), and a driven bevel gear (14). One end of the support frame (4) is fixed on the knife holder (2) adjacent to the cleaning roller (7), and the other end of the support frame (4) is rotatably connected to the driving bevel gear (13) through a rotating shaft. The synchronizing element (12) consists of two synchronous pulleys and a synchronous belt. One synchronous pulley is fixed on the main shaft (10), and the other synchronous pulley is coaxially connected to the driving bevel gear (13). The two ends of the synchronous belt are respectively sleeved on the two synchronous pulleys. The driven bevel gear (14) is fixed to the end of the connecting shaft (9), and the driven bevel gear (14) is connected to the main shaft (10). The moving bevel gear (13) meshes, and the connecting shaft (9) passes through the housing (1) and is slidably connected to the housing (1), so that the connecting shaft (9) can move up and down with the blade holder (2). A bearing sleeve (8) is fixed on the blade holder (2) adjacent to the cleaning roller (7). The connecting shaft (9) is rotatably connected to the bearing sleeve (8) through the bearing. The cleaning roller (7) is composed of a support roller and bristles evenly distributed on the support roller. The end of the connecting shaft (9) away from the driven bevel gear (14) is fixedly connected to the end of the support roller. The bristles are parallel to the blade (5). The first synchronous pulley is driven to rotate through the main shaft (10), so that the other synchronous pulley moves synchronously through the synchronous belt, thereby driving the active bevel gear (13) to drive the driven bevel gear (14) to rotate, so that the connecting shaft (9) drives the cleaning roller (7) to rotate to clean the wire.

[0025] Furthermore, such as Figure 3 and Figure 5 As shown, considering the tensioning problem of the synchronous belt when the active bevel gear (13) and support frame (4) rise and fall with the tool holder (2), a tensioning mechanism is installed in the housing (1). The tensioning mechanism consists of a tensioning wheel (15), a wheel frame (16), a guide rod (17), and a tension spring (18). The tensioning wheel (15) is rotatably connected to the wheel frame (16) through a rotating shaft. The synchronous belt passes between the tensioning wheel (15) and the wheel frame (16). The tension spring (18) One end of the spring (18) is fixed to the inner wall of the housing (1), and the other end of the spring (18) is fixed to the wheel frame (16). One end of the guide rod (17) is fixed to the inner wall of the housing (1), and the other end of the guide rod (17) passes through the wheel frame (16) and is slidably connected to the wheel frame (16). When the synchronous belt pulley moves, the synchronous belt is always pulled by the tensioning wheel (15), and the tension is provided by the spring (18). This ensures that the synchronous belt is always in a taut state.

[0026] Working principle: When in use, power on the equipment and feed the wire through the external winding and unwinding device. The wire passes between the two blades (5). The motor (19) drives the main shaft (10) to rotate, so that the main shaft (10) drives the two linkage components (3) to move towards each other through the drive gear (11). This causes the two blade holders (2) to clamp the wire together with the two blades (5). When the wire passes between the two blades (5), it can be cut by the blades (5) to perform wire stripping.

[0027] During the wire pulling process, the motor (19) drives the main shaft (10) to rotate continuously. The main shaft (10) drives the active bevel gear (13) to rotate through the synchronizing component (12), which in turn drives the driven bevel gear (14) to drive the cleaning roller (7) to roll and clean the surface of the wire through the connecting shaft (9).

[0028] When cutting some shielded wires, the resistance encountered by the blade (5) when it comes into contact with the shielding layer will increase. Once the resistance is greater than the elastic force of the spring (63), the connecting rod (62) will retract towards the cylinder (61), which will loosen the clamping force of the two blades (5) and ensure that the blade (5) can only peel off the rubber layer on the surface of the wire, thus avoiding the blade (5) from scratching the shielding layer due to excessive force when it comes into contact with the shielding layer.

[0029] By rotating the screw (65), the top plate (64) can be pushed to compress the spring (63), increasing the elastic force applied by the spring (63) to the connecting rod (62), which can control the retraction and release force of the blade (5), and is suitable for the actual working needs of different wires.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
