Description

Technical Field

[0001] This invention relates to the field of cable slicing device technology, specifically to a cable slicing device with a differential speed adjustment mechanism. Background Technology

[0002] Wires are widely used in industry, such as industrial electrical equipment and electronic products. Currently, many wires require the outer sheath to be stripped before wiring to expose the conductors at both ends.

[0003] Chinese patent literature discloses a fully automatic large-square-meter cable cutting and stripping machine, including a rotary cutting mechanism. The rotary cutting mechanism includes a base, a hollow mounting shaft, a rotating sleeve, a rotary cutting blade mounting plate, a dial plate, a first dial wheel, a second dial wheel, and a rotary cutting blade, as well as a cutting blade infeed drive mechanism. The cutting blade infeed drive mechanism drives the first dial wheel and the second dial wheel to rotate synchronously or differentially. The cutting blade infeed drive mechanism includes a motor assembly, a first active synchronous wheel, a second active synchronous wheel, a sliding plate, a servo power mechanism, a passive synchronous wheel, a first guide wheel, and a second guide wheel. The motor assembly is mounted on the base; the first and second active synchronous pulleys are sleeved on the rotating shaft of the motor assembly; the base has a second sliding groove, and the sliding plate is disposed in the second sliding groove. The servo power mechanism drives the sliding plate to slide along the second sliding groove. Two passive synchronous pulleys are rotatably connected to the sliding plate. Two first guide pulleys are disposed on one side of the second sliding groove, and two second guide pulleys are disposed on the other side of the second sliding groove. A first synchronous belt is wrapped around the outside of the first active synchronous pulley, the two passive synchronous pulleys, and the first actuating pulley. The two first guide pulleys and the two second guide pulleys limit the outside of the first synchronous belt. A second synchronous belt is wrapped around the second active synchronous pulley and the second actuating pulley. The servo power mechanism drives the sliding plate to slide. When the sliding plate slides, the two passive synchronous pulleys pull the first synchronous belt to increase or decrease the transmission speed, thereby achieving differential speed. Adjustment requires repeatedly adjusting the position of the sliding plate to achieve differential or same-speed rotation, which is cumbersome. Frequent pulling of the synchronous belt will also aggravate the wear of the synchronous belt. Summary of the Invention

[0028] Please see Figure 1-9 An embodiment of the present invention provides a cable slicing device with a differential speed adjustment mechanism, comprising a support base 1, an outer support tube 7 horizontally rotatably mounted on the top of the support base 1 via bearings, a feed mechanism 2 mounted on the front end face of the outer support tube 7, and a second pulley mechanism 5 for driving the outer support tube 7 to rotate. The top of the support base 1 is provided with an active rotating shaft 3 for driving the second pulley mechanism 5 to rotate and a rotation drive mechanism 4 for driving the active rotating shaft 3 to rotate. The active rotating shaft 3 is mounted directly below the outer support tube 7 via bearings. The rotation drive mechanism 4 specifically includes a driven wheel fixed on the active rotating shaft 3, an active wheel mounted on one side of the driven wheel, a synchronous belt connecting the active wheel and the driven wheel, and a motor for driving the active wheel to rotate.

[0029] refer to Figure 6 The second pulley mechanism 5 includes a second driven wheel 501 fixed on the outer support tube 7, a second drive wheel 502 fixed on the active rotating shaft 3, and a second synchronous belt 503 connecting the second driven wheel 501 and the second drive wheel 502. A guide wheel for adjusting tension is provided on one side of the second synchronous belt 503. The active rotating shaft 3 drives the outer support tube 7 to rotate through the second pulley mechanism 5.

[0030] refer to Figure 6The inner support tube 8 is movably inserted into the outer support tube 7 to support the cable. A fixed bracket 9 is installed at the end of the outer support tube 7 away from the feed mechanism 2, and the fixed bracket 9 is provided with bolts to fix the inner support tube 8, so as to facilitate the replacement of inner support tubes 8 of different sizes according to different cable diameters.

[0031] refer to Figure 2-6 The feed mechanism 2 includes a mounting plate 201, a cutter body 202, a drive plate 203, a slider 204, a first pulley mechanism 205, and a panel 206. In this embodiment, both the mounting plate 201 and the drive plate 203 are circular plate structures. The mounting plate 201 is fixed to the front end face of the outer support tube 7, allowing the mounting plate 201 to rotate synchronously with the outer support tube 7. Several cutter bodies 202 are slidably disposed on the front end face of the mounting plate 201 via sliders 204. In this embodiment, the number of cutter bodies 202 is four. The drive plate 203 is coaxially sleeved on the outer support tube 7 at the rear end face of the mounting plate 201, and the drive plate 203 and the outer support tube 7 are rotatably connected by bearings. The drive plate 203 is provided with several arc-shaped grooves 2031 corresponding one-to-one with the sliders 204. The arc-shaped grooves 2031 are all from near the... The drive disk 203 has an arc-shaped structure with a gradually increasing radius from the center to the outer circumference. The mounting disk 201 has several grooves 2011 that correspond one-to-one with the cutter body 202, allowing the cutter body 202 to slide along the radial direction of the mounting disk 201. Each slider 204 is equipped with a connector, which passes through the groove 2011 and is rotatably disposed inside the arc-shaped groove 2031. When the connector slides inside the arc-shaped groove 2031, its distance from the center of the drive disk 203 can be adjusted, thereby synchronously adjusting the position of each slider 204 and the cutter body 202 from the center, realizing the cutting and retraction. The panel 206 is fixed on the front end face of the mounting disk 201 and is used to block and limit the cutting body 202. The first pulley mechanism 205 is used to drive the drive disk 203 to rotate, realizing the cutting and retraction.

[0032] refer to Figure 6 The first pulley mechanism 205 is installed at one end of the active rotating shaft 3 via the differential adjustment mechanism 6. The differential adjustment mechanism 6 is used to drive the first pulley mechanism 205 to rotate synchronously or differentially with the active rotating shaft 3. When the first pulley mechanism 205 rotates synchronously with the active rotating shaft 3, the outer support tube 7 rotates synchronously with the drive disk 203. When the first pulley mechanism 205 rotates differentially with the active rotating shaft 3, the outer support tube 7 and the drive disk 203 rotate at different speeds. When the speeds are different, the connecting piece on the slider 204 slides inside the arc groove 2031, causing the slider 204 and the cutter body 202 to slide back and forth along the length direction of the groove 2011. When each slider 204 moves towards the center synchronously, the cutting tool is advanced. When each slider 204 moves outward circumferentially, the cutting tool is retracted.

[0033] reference Figure 6-9The differential adjustment mechanism 6 includes an adjusting rod 601, a lead screw seat 602, a driven rotating shaft 603, an adjusting block 604, a linear drive mechanism 605, and a guide mechanism 606. The driving rotating shaft 3 is a hollow cylindrical structure with both ends open. The driven rotating shaft 603 is coaxially rotatably mounted at one end of the driving rotating shaft 3 near the second pulley mechanism 5. One end of the driven rotating shaft 603 extends to the outside of the driving rotating shaft 3. Specifically, the driven rotating shaft 603 is rotatably inserted into one end of the driving rotating shaft 3 via a bearing. The driven rotating shaft 603 can rotate relative to the driving rotating shaft 3. The driven rotating shaft 603 is used to drive the first pulley mechanism 205 to rotate. The first pulley mechanism 205 includes a first driven wheel 2051 coaxially fixed to the rear end face of the drive disc 203, a first driving wheel 2052 fixed to the driven rotating shaft 603, and a first synchronous belt 2053 connecting the first driven wheel 2051 and the first driving wheel 2052. A guide wheel for adjusting tension is provided on one side of the first synchronous belt 2053. By adjusting the driven rotating shaft 603... The rotational speed of the first pulley mechanism 205 can be adjusted by adjusting the rotational speed of the drive rotating shaft 3. The lead screw seat 602 is fixedly installed at the end of the drive rotating shaft 3 away from the driven rotating shaft 603. One end of the adjusting rod 601 is provided with a threaded section 6011 that matches the lead screw seat 602, and the other end of the adjusting rod 601 is provided with a drive section 6012. A connecting shaft hole 6031 that matches the drive section 6012 is provided through the center of the driven rotating shaft 603. In this embodiment, the connecting shaft hole 6031 is an oblong hole, but it can also be adjusted as needed. To configure it to other shapes, the drive section 6012 is inserted into the connecting shaft hole 6031 to drive the driven rotating shaft 603 and the adjusting rod 601 to rotate synchronously. One end of the adjusting rod 601 extends through the lead screw seat 602 to the outside of the driving rotating shaft 3 and is rotatably connected to the adjusting block 604 via a bearing. When one end of the adjusting rod 601 is in a limited position, the adjusting rod 601 and the lead screw seat 602 can rotate synchronously. The linear drive mechanism 605 is used to drive the adjusting block 604 to slide back and forth along the axial direction of the driven rotating shaft 603.The linear drive mechanism 605 includes a lead screw mounted parallel to the active rotation axis 3 and a drive mechanism for rotating the lead screw. The drive mechanism specifically includes a drive motor mounted on the top of the support base 1 via a support plate, a drive wheel mounted on the drive motor shaft, a driven wheel mounted on one side of the drive wheel, and a synchronous belt connecting the drive wheel and the driven wheel. An adjusting block 604 is connected to the lead screw via a nut and is used to drive the adjusting block 604 to slide back and forth along the length of the lead screw. Simultaneously, when the position of the adjusting rod 601 does not need to be adjusted, one end of the adjusting rod 601 can be limited to prevent it from sliding axially under the rotation of the lead screw seat 602. The linear drive mechanism 605 can also be configured as a cylinder, hydraulic telescopic rod, or other structures. The bottom end of the adjusting block 604 is provided with a guide mechanism 606 to limit its back-and-forth sliding along the axial direction of the active rotation axis 3. The guide mechanism 606 is a guide rail mounted on the top of the support base 1 parallel to the lead screw. The bottom end of the adjusting block 604 is slidably connected to the guide rail, improving the stability of the adjusting block 604's movement.

[0034] Working principle: During operation, one end of the cable is inserted into the inner support tube 8. At the start of operation, the rotary drive mechanism 4 drives the active rotary shaft 3 to rotate. The lead screw seat 602 is fixed to one end of the active rotary shaft 3, so the lead screw seat 602 rotates synchronously with the active rotary shaft 3. Due to the threaded engagement between the threaded section 6011 and the lead screw seat 602, the linear drive mechanism 605 limits one end of the adjusting rod 601, thereby causing the adjusting rod 601 to rotate synchronously with the lead screw seat 602. The drive section 6012 is always inserted into the driven rotary shaft 603. Inside the central connecting shaft hole 6031, the adjusting rod 601 drives the driven rotating shaft 603 to rotate synchronously with the driving rotating shaft 3. The first driving wheel 2052 is fixed on the driven rotating shaft 603, and the second driving wheel 502 is fixed on the driving rotating shaft 3, thereby causing the driving disc 203 to rotate synchronously with the outer support tube 7. During differential adjustment, the linear drive mechanism 605 and the adjusting block 604 push the adjusting rod 601 to slide back and forth along the length direction of the driving rotating shaft 3. The driving section 6012 always slides inside the connecting shaft hole 6031. The adjusting rod 601 is no longer rotated synchronously with the lead screw seat 602, and its rotational speed changes accordingly. This causes a change in the rotational speed between the driven rotating shaft 603 and the driving rotating shaft 3, achieving differential rotation between the drive disk 203 and the mounting disk 201. When the rotational speeds of the mounting disk 201 and the drive disk 203 are different, the connecting piece on the slider 204 slides inside the arc-shaped groove 2031, causing the slider 204 and the cutter body 202 to slide back and forth along the length of the groove 2011. When all sliders 204 synchronously move towards the center... When the cable is inserted into the inner support tube 8, the active rotating shaft 3 drives each cutter body 202 to rotate and perform rotary cutting, cutting the outer sheath of the cable into a ring-shaped slit. When each cutter body 202 slides outward in circumference in sync, the cable is retracted. When the cable is inserted into the inner support tube 8, the position of the cutter 601 only needs to be adjusted once. When it needs to rotate at the same speed again, the movement can be stopped. There is no need to reset the cutter 601. The operation is convenient and quick.

[0035] 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.
