Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, in particular to a continuous automatic stripping device for cable production. Background Art

[0002] The stripping device of prior art generally cuts the insulation sheath of cable by cutting knife, and then uses the cable core and the insulation sheath to be rolled up respectively, thereby separating the cable core and the insulation sheath of cable. However, when cutting the insulation sheath, the cutting track on the insulation sheath is straight line, and the cross section of the insulation sheath is still a complete circle, that is, the insulation sheath is still relatively tightly wrapped on the surface of cable core, which makes it difficult to separate the insulation sheath from the cable core. When the cable core and the insulation sheath are rolled up by the winding device, the insulation sheath may pull the cable core, causing the cable core to bend. After the cable core is bent, the cutting depth of the cutter on the cable core cannot be guaranteed, and the rolling up of the cable core is affected. In addition, the insulation sheath may be broken due to excessive pulling force, especially the insulation sheath with thinner thickness. Summary of the Invention

[0017] Furthermore, a plurality of spiral grooves are provided on the periphery of the separation roller.

[0018] Furthermore, the pivot is provided with a skin-lifting assembly, which includes a sliding ring slidably mounted on an end of the pivot away from the cutting assembly, the sliding ring being key-connected with the periphery of the pivot, a pawl being fixed to the periphery of the sliding ring, and a lateral spacing dimension between the pawl's most distal end from the pivot axis and the pivot being greater than the outer diameter of the cable;

[0026] In the present invention, the end of the insulating sheath separated from the cable core is inserted into the gap between the opposite surfaces of the two synchronous belts, and then the two synchronous belts rotate synchronously in opposite directions, thereby biting the end of the insulating sheath into the gap, and then the insulating sheath is wound up by an external winding device, so that the insulating sheath can be pressed and straightened when it is wound up, so that the insulating sheath is as unfolded as possible.

[0044] like Figures 1 to 9 As shown, an embodiment of the present invention provides a continuous automatic stripping device for cable production, including a machine base 2, a positioning seat 6 is connected to the outer wall of one side of the machine base 2 by screws, and a lifting cylinder 5 is vertically installed on both sides of the bottom of the positioning seat 6, and the cylinder rod of the lifting cylinder 5 penetrates the positioning seat 6 and slides freely. The ends of the cylinder rod of the lifting cylinder 5 are respectively fixed with ear blocks, and the two ear blocks are jointly fixed with a cutter mounting seat 7. The cutter mounting seat 7 can be integrally formed with the ear blocks. The cutter mounting seat 7 is located on the upper side of the positioning seat 6, and an arc groove is provided between the opposite surfaces of the cutter mounting seat 7 and the positioning seat 6. When the opposite surfaces of the cutter mounting seat 7 and the positioning seat 6 are against each other, the two arc grooves form a positioning hole 11 in the form of a through hole, and the positioning The aperture of the hole 11 matches the outer diameter of the cable, so that the cable (unstripped) can freely pass through the positioning hole 11. A through-hole-shaped cutter mounting opening is provided on the top of the cutter mounting seat 7. A cutter mounting frame is screwed to the cutter mounting seat 7, and a cutter 12 is installed on the cutter mounting frame. The cutter 12 is located in the cutter mounting opening. The blade of the cutter 12 is arc-shaped and penetrates into the arc-shaped groove of the cutter mounting seat 7. In this way, when the cable passes through the positioning hole 11, the blade of the cutter 12 can produce a cutting effect on the insulating sheath of the cable. In addition, the length of the cutter blade 12 extending into the arc-shaped groove is consistent with the wall thickness of the insulating sheath, so that when the cutter 12 cuts the cable insulation, it will not damage the cable core of the cable.

[0045] A support 8 is also connected to the outer wall of the machine base 2 by screws, and a cable through-hole 13 is provided on the outer wall on both sides of the axial direction of the support 8 corresponding to the positioning hole 11. The positioning hole 11 is coaxial with the cable through-hole 13, and the outer diameter of the cable is adapted to the aperture size of the cable through-hole 13. The support 8 is horizontally rotatably connected with a pivot 17 on both sides through a bearing, and a separation roller 9 is coaxially fixed to the periphery of the pivot 17. The periphery of the separation roller 9 is provided with a plurality of spiral grooves in an array along its own axial direction. Two motor seats are installed on the outer wall of the support 8, and a servo motor 10 is installed on the motor seat. The motor shafts of the two servo motors 10 are respectively connected to the end portions of the two pivots 17 through couplings. The two servo motors 10 drive the pivot 17 to rotate synchronously in opposite directions, thereby enabling the two separation rollers 9 to rotate synchronously in opposite directions. The other two separation rollers 9 are respectively located on both sides of the radial direction of the cable through-hole 13, and the two separation rollers 9 rotate synchronously in opposite directions, forming a clamping space between the two, and the lateral spacing dimension of the clamping space is not greater than the outer diameter dimension of the cable.

[0046] In addition, the axis of the cable through-hole 13 is located below the axis of the separation roller 9, and a bracket 14 is screwed to the outer wall of the support 8 adjacent to the positioning seat 6. The bracket 14 is located below the support 8. In addition, the outer wall of the bracket 14 is rotatably connected to a swing rod 16, and the swing rod 16 is rotatably connected to an extrusion wheel 19. The extrusion wheel 19 is located below the clamping space. When the cable passes through a cable through-hole 13 adjacent to the positioning seat 6 to between the two separation rollers 9, the swing rod 16 swings upward, thereby causing the periphery of the extrusion wheel 19 to squeeze the cable, so that the cable is stuck between the two separation rollers 9. During the operation, the two separation rollers 9 produce an extrusion effect on the insulating sheath of the cable, and then the separation rollers 9 rotate synchronously in opposite directions, so that the insulating sheath of the cable is peeled off radially outward from the cutting position as the origin. In addition, the lower end of the bracket 14 is rotatably connected to a movable hinge seat 21, and a tightening cylinder 15 is installed on the outer wall of the movable hinge seat 21. The tightening cylinder 15 drives the connection block 20, and the connection block 20 is hinged to the swing rod 16. The cylinder rod of the tightening cylinder 15 drives the connection block 20 to move up and down, thereby driving the swing rod 16 to rotate up and down along the hinge with the bracket 14.

[0047] The pivot 17 is slidably fitted with a sliding ring 18 at one end away from the positioning seat 6, and the sliding ring 18 is key-connected to the periphery of the pivot 17. A pusher claw 25 is fixed to the periphery of the sliding ring 18. The lateral spacing between the pusher claw 25 and the pivot 17 at the farthest end from the axis of the pivot 17 is greater than the outer diameter of the cable. A fixing ring 22 is detachably connected to the outer wall of the support 8. A protrusion 27 is fixed to the end face of the fixing ring 22 facing the sliding ring 18. The surface of the protrusion 27 smoothly transitions to the end face of the fixing ring 22. A mounting pin 24 is vertically fixed to the end face of the sliding ring 18 facing the fixing ring 22. A ball 26 is rotatably embedded at the end of the mounting pin 24. The ball 26 cooperates with the protrusion 27 and the fixing ring 22. A return spring is wrapped around the periphery of the pivot 17. 23. The two ends of the return spring 23 in the elastic direction elastically press against the sliding ring 18 and the end surface of the separation roller 9 respectively. The return spring 23 generates an elastic pressing force on the sliding ring 18, so that the sliding ring 18 has a tendency to move in the direction away from the separation roller 9, and then when the pivot 17 rotates, the ball 26 can alternately roll on the end surface of the fixed ring 22 and the surface of the protrusion 27. When the ball 26 rolls from the end surface of the fixed ring 22 to the surface of the protrusion 27, it will generate an extrusion force on the sliding ring 18, thereby driving the sliding ring 18 to move in the direction of the separation roller 9. Conversely, when the ball 26 rolls from the surface of the protrusion 27 to the end surface of the fixed ring 22, the elastic potential energy of the return spring 23 is released, thereby driving the sliding ring 18 to move in the direction away from the separation roller 9.

[0048] The outer wall of the machine base 2 is rotatably connected to a synchronous pulley 1 through a rotating shaft. There are two synchronous pulleys 1 in each group and they are jointly covered with a synchronous belt 4. The two groups of synchronous pulleys 1 are arranged from top to bottom, and there is a gap between the opposite surfaces of the two synchronous pulleys 1. Two tensioning synchronous pulleys 3 are rotatably connected to the outer wall of the machine base 2. The two tensioning synchronous pulleys 3 are respectively located between the two synchronous belts 4 and are used in conjunction with the synchronous belt 4. At least one motor and gear box are installed inside the machine base 2 to drive the two groups of synchronous pulleys 1 and the tensioning synchronous pulley 3 to rotate, and to make the two synchronous belts 4 rotate synchronously in opposite directions. This is a common method used by those skilled in the art and will not be described here.

[0049] The working principle of this embodiment is as follows:

[0050] Since the cable core and insulating sheath of the cable need to be wound up separately through two winding devices (the cable core winding device and the sheath winding device), in the initial stage of stripping, the cable core and insulating sheath need to be separated manually and wound up on the two winding devices respectively. In this way, the device can be used for continuous stripping operations, which does not affect the implementation effect of this embodiment.

[0051] In the initial stage, the lifting cylinder 5 is first started, and the cylinder rod of the lifting cylinder 5 is extended to drive the cutter mounting seat 7 to move upward, so that the cutter mounting seat 7 and the positioning seat 6 are separated, and then the cable end is placed in the arc groove of the positioning seat 6, and then the lifting cylinder 5 is started again, and the cylinder rod of the lifting cylinder 5 is shortened to drive the cutter mounting seat 7 to move downward, so that the opposite surfaces of the cutter mounting seat 7 and the positioning seat 6 are against each other, and then the blade of the cutter 12 cuts the insulating sheath of the cable end, and then the cable is manually pushed to make the cable end pass through the positioning hole 11. During the passing process, the cutter 12 cuts the cable The insulating sheath at the end is cut open, and an incision is formed on the upper outer wall of the insulating sheath of the cable. The incision is straight. Then the cut end of the cable is pulled and inserted into the cable opening 13. Then, a tool is used to separate the cable core and the insulating sheath. The insulating sheath passes through the gap between the two synchronous belts 4. The synchronous pulley 1 is started, so that the synchronous belt 4 has a biting effect on the insulating sheath. The end of the cable core then passes through another cable opening 13 and is wound on the cable core winding device. When the insulating sheath passes through between the synchronous belts 4, it is wound on the sheath winding device. The above completes the initial stage of work during the continuous cable stripping operation.

[0052] Continuous stripping operation stage: start the pressing cylinder 15, and the cylinder rod of the pressing cylinder 15 is extended to drive the connecting block 20 to move upward, and drive the swing rod 16 to swing upward, so that the upper side of the periphery of the extrusion wheel 19 squeezes the insulating outer sheath of the cable, so that the lowermost outer wall of the periphery of the cable outer sheath is squeezed by the extrusion wheel 19 and drives the cable to move upward slightly until the cable is squeezed by the two separation rollers 9.

[0053] The external cable core winding device and the outer sheath winding device are started and the cable core and the insulating sheath are wound, so that the cable is pulled and moved. During the movement, the blade of the cutter 12 continuously cuts the insulating sheath of the cable, so that a linear incision is formed on the upper side of the peripheral edge of the insulating sheath. The two separating rollers 9 are started synchronously and rotate in opposite directions synchronously. Figure 5 The separating roller 9 on the left rotates clockwise, and the separating roller 9 on the right rotates counterclockwise, so that the two separating rollers 9 produce a downward stripping force on the insulating sheaths on both sides of the incision. At the same time, due to the squeezing of the insulating sheath by the extrusion wheel 19, the cable will not move downward when the insulating sheath is stripped by the separating roller 9. This causes relative movement between the insulating sheath and the cable core, and then the insulating sheath is squeezed and rubbed by the separating roller 9 and stripped downward. At this time, the insulating sheath may not be completely stripped off by the separating roller 9 and is still stuck on the cable core, but the incision is enlarged.

[0054] The cam 18 is then pulled away from the cable core by the spring 25 and the spring 26 is pulled away from the cable core by the spring 27. The cam 18 is pulled away from the cable core by the spring 27 and the spring 26 is pulled away from the cable core by the spring 27.

[0055] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. While specific details are described in detail in the preferred embodiments to provide a thorough understanding of the present invention, those skilled in the art will be able to fully understand the present invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
