Description

Technical Field

[0001] This utility model belongs to the technical field of take-up devices, specifically relating to a take-up device for a cable processing stranding machine. Background Technology

[0002] In the cable manufacturing process, the stranding process is a crucial step in twisting multiple conductor cores together at a certain pitch to form a stranded cable. After stranding is completed, the cable must immediately enter the winding stage, where a special spool is used to wind and collect the cable for subsequent processes such as insulation extrusion, sheath forming, inspection, and packaging.

[0003] In existing technologies, when winding twisted cables, the method often involves fixing the spool to the shaft of a winding machine, which then drives the spool to rotate. Specifically, the spool's shaft hole must first be fitted onto the shaft so that one side of the spool contacts the clamp on the outside of the shaft. Then, a manually adjustable clamp is pushed until it contacts the other side of the spool. The clamp on the outside of the shaft, in conjunction with the reel clamp, clamps the spool, allowing it to rotate with the shaft. However, this method is overly cumbersome and affects the efficiency of both the installation before winding and the disassembly after winding. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a take-up device for a cable processing stranding machine. By setting up an internal support mechanism that can be quickly adjusted using a bidirectional threaded rod and achieves efficient vibration resistance and anti-loosening function through a spring friction enhancement design, it enables quick installation, firm tightening, and convenient disassembly of the winding drum. It has the advantages of simple structure, stable adjustment, strong clamping force, and no damage to the drum body, and can be applied to winding drums with different inner diameter shaft holes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a take-up device for a cable processing stranding machine, comprising a base, a bracket on the top of the base, a main rotating shaft passing through and mounted on the two sides of the bracket via bearings, a motor mounted on one side of the bracket, the output end of the motor connected to one end of the main rotating shaft, the other end of the main rotating shaft connected to a mounting cylinder, a limiting plate fixedly mounted on the outer side of one end of the mounting cylinder, a first guide groove passing through the inner and outer sides of the mounting cylinder, a second guide groove passing through the two sides of the limiting plate, a bidirectional threaded rod rotatably mounted on the inner side of the mounting cylinder, an adjusting rotating shaft connected to one end of the bidirectional threaded rod, a first threaded transmission sleeve and a second threaded transmission sleeve respectively threadedly connected to the outer sides of two oppositely oriented threads on the bidirectional threaded rod, a first bearing seat provided on the outer side of both the first and second threaded transmission sleeves, the first bearing seat rotatably connected to one end of a rotating arm, the other end of the rotating arm rotatably connected to a second bearing seat, and an inner support strip fixedly connected to the outer side of the second bearing seat.

[0006] The beneficial effects of this utility model are as follows: This device has an internal support mechanism that enables rapid adjustment using a bidirectional threaded rod and achieves efficient anti-vibration and anti-loosening functions through a spring friction enhancement design. It enables rapid installation, firm tightening, and convenient disassembly of the winding drum. It has the advantages of simple structure, stable adjustment, strong clamping force, and no damage to the drum body. It is also suitable for winding drums with different inner diameter shaft holes, and is especially suitable for efficient winding operations in the winding stage of cable processing stranding machine.

[0007] To ensure the stability of the support between the inner shaft holes of the cable reel:

[0008] As a further improvement to the above technical solution: the number of the first guide groove, the second guide groove, the first bearing seat, the rotating arm, the second bearing seat, and the inner support strip support are all four sets.

[0009] The beneficial effect of this improvement is that by setting up four sets of internal support strips, the stability of the support between the inner shaft holes of the winding drum is ensured.

[0010] To ensure that the first threaded drive sleeve, the second threaded drive sleeve, and the rotating arm all remain in a stable state:

[0011] As a further improvement to the above technical solution: one end of the inner support strip is inserted into the second guide groove and slidably connected thereto, and the rotating arm passes through the first guide groove from the inside of the mounting cylinder to the outside of the mounting cylinder.

[0012] The beneficial effects of this improvement are as follows: by sliding and limiting one end of the inner support strip through the second guide groove, the first threaded transmission sleeve, the second threaded transmission sleeve, and the rotating arm can all maintain a stable state. The first threaded transmission sleeve and the second threaded transmission sleeve will not rotate with the rotation of the bidirectional threaded rod, nor will they wobble. The first guide groove provides a channel for the passage and rotation of the rotating arm.

[0013] To rotate the bidirectional threaded rod:

[0014] As a further improvement to the above technical solution: a sealing plate is fixedly provided at one end of the mounting cylinder, one end of the adjusting shaft passes through the sealing plate and is connected to the damping bearing seat, and a rotating handle is rotatably installed on the inner side of the damping bearing seat.

[0015] When the double-threaded rod does not need to be rotated, the handle is rotated to a horizontal position through its rotational relationship with the damping bearing seat. The damping force of the damping bearing seat keeps it in this position so as not to obstruct the installation and removal of the winding drum. When the double-threaded rod needs to be rotated, it can be rotated to a perpendicular position with the double-threaded rod through the damping bearing seat, and then the double-threaded rod can be rotated by turning the handle.

[0016] To increase the friction between the user's hand and the handle when turning it:

[0017] As a further improvement to the above technical solution: a rubber sleeve is provided on the outer side of the rotating handle, the rubber sleeve is composed of two rubber pieces, and the rotating handle is bonded and fixed to the two rubber pieces.

[0018] The beneficial effects of this improvement are: the rubber sleeve can increase the friction between the user's hand and the handle when turning the handle, and improve the comfort of contact.

[0019] To improve the stability of the internal support mechanism:

[0020] As a further improvement to the above technical solution: two sets of springs are sleeved on the outer side of the bidirectional threaded rod, and the two sets of springs are respectively located between the first threaded transmission sleeve and the inner wall of the left end of the mounting cylinder and between the second threaded transmission sleeve and the sealing plate.

[0021] The beneficial effects of this improvement are as follows: the spring applies pressure to the first and second threaded transmission sleeves through its own elastic force, which enhances the axial friction between the two sets of threaded pairs, namely the bidirectional threaded rod and the first and second threaded transmission sleeves, thereby effectively improving the locking stability between the transmission sleeve and the bidirectional threaded rod and ensuring that the inner support mechanism does not loosen or deviate unexpectedly during operation.

[0022] To prevent the spool from slipping during the winding process:

[0023] As a further improvement to the above technical solution: a rubber pad is bonded to the outer side of the inner support strip.

[0024] The beneficial effects of this improvement are as follows: the rubber pad increases the friction between the inner support strip and the winding drum shaft hole when the inner support strip tightens the winding drum shaft hole, thereby improving the tightening effect and preventing the winding drum from slipping during the winding process.

[0025] As a further improvement to the above technical solution: a winding drum is sleeved on the outer side of the mounting cylinder.

[0026] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0034] like Figure 1-5As shown, a take-up device for a cable processing stranding machine includes a base 1, a bracket 2 on the top of the base 1, a main rotating shaft 3 passing through and mounted on the two sides of the bracket 2 via bearings, a motor 4 mounted on one side of the bracket 2, the output end of the motor 4 connected to one end of the main rotating shaft 3, and the other end of the main rotating shaft 3 connected to a mounting cylinder 5. A limiting plate 6 is fixedly provided on the outer side of one end of the mounting cylinder 5, a first guide groove 8 passing through the inner and outer sides of the mounting cylinder 5, and a second guide groove 9 passing through the two sides of the limiting plate 6. A bidirectional threaded rod 10 is rotatably mounted on the inner side of the device. One end of the bidirectional threaded rod 10 is connected to an adjusting shaft 11. The two oppositely oriented threads on the bidirectional threaded rod 10 are respectively threaded to a first threaded transmission sleeve 14 and a second threaded transmission sleeve 15. The outer sides of the first threaded transmission sleeve 14 and the second threaded transmission sleeve 15 are each provided with a first bearing seat 16. The first bearing seat 16 is rotatably connected to one end of a rotating arm 17. The other end of the rotating arm 17 is rotatably connected to a second bearing seat 18. An inner support strip 19 is fixedly connected to the outer side of the second bearing seat 18.

[0035] This device features an internal support mechanism that allows for rapid adjustment using a bidirectional threaded rod and achieves efficient vibration resistance and anti-loosening function through a spring friction enhancement design. It enables quick installation, secure tightening, and convenient disassembly of the winding drum. It boasts advantages such as simple structure, stable adjustment, strong clamping force, and no damage to the drum body. It is also suitable for winding drums with different inner diameter shaft holes, and is particularly suitable for efficient winding operations in the winding stage of cable processing stranding machines.

[0036] The number of the first guide groove 8, the second guide groove 9, the first bearing seat 16, the rotating arm 17, the second bearing seat 18, and the inner support strip 19 are all four sets.

[0037] The four sets of internal support strips 19 ensure the stability of the support between the inner shaft holes of the winding drum.

[0038] One end of the inner support strip 19 is inserted into the second guide groove 9 and slidably connected thereto. The rotating arm 17 passes through the first guide groove 8 from the inside of the mounting cylinder 5 to the outside of the mounting cylinder 5.

[0039] By sliding and limiting one end of the inner support strip 19 through the second guide groove 9, the first threaded transmission sleeve 14, the second threaded transmission sleeve 15, and the rotating arm can all maintain a stable state. The first threaded transmission sleeve 14 and the second threaded transmission sleeve 15 will not rotate with the rotation of the bidirectional threaded rod 10, nor will they shake. The first guide groove 8 provides a channel for the passage and rotation of the rotating arm 17.

[0040] One end of the mounting cylinder 5 is fixedly provided with a sealing plate 7, and one end of the adjusting shaft 11 passes through the sealing plate 7 and is connected to the damping bearing seat 12. A rotating handle 13 is rotatably installed on the inner side of the damping bearing seat 12.

[0041] When the double-threaded rod 10 does not need to be rotated, the handle 13 is rotated to a horizontal position through its rotational relationship with the damping bearing seat 12. The damping force of the damping bearing seat 12 keeps it in this position so as not to obstruct the installation and removal of the winding drum. When the double-threaded rod 10 needs to be rotated, it can be rotated to a perpendicular position with the double-threaded rod 10 through the damping bearing seat 12, and then the double-threaded rod 10 can be rotated by turning the handle 13.

[0042] A rubber sleeve 22 is fitted on the outer side of the rotating handle 13. The rubber sleeve 22 is composed of two rubber pieces, upper and lower. The rotating handle 13 is bonded and fixed to the upper and lower rubber pieces.

[0043] The rubber sleeve 22 increases the friction between the user's hand and the handle 13 when the user turns the handle 13, and improves the comfort of contact.

[0044] Two sets of springs 20 are sleeved on the outer side of the bidirectional threaded rod 10. The two sets of springs 20 are located between the first threaded transmission sleeve 14 and the inner wall of the left end of the mounting cylinder 5, and between the second threaded transmission sleeve 15 and the sealing plate 7, respectively.

[0045] The spring 20 applies pressure to the first threaded transmission sleeve 14 and the second threaded transmission sleeve 15 through its own elastic force, thereby enhancing the axial friction between the two sets of threaded pairs, namely the bidirectional threaded rod 10 and the first threaded transmission sleeve 14 and the second threaded transmission sleeve 15. This effectively improves the locking stability between the transmission sleeve and the bidirectional threaded rod 10, ensuring that the inner support mechanism does not loosen or deviate unexpectedly during operation.

[0046] A rubber pad 23 is bonded to the outer side of the inner support strip 19.

[0047] The rubber pad 23 increases the friction between the inner support strip 19 and the shaft hole of the winding drum 21 when the inner support strip 19 tightens the shaft hole of the winding drum 21, thereby improving the tightening effect and preventing the winding drum 21 from slipping during the winding process.

[0048] The outer side of the mounting cylinder 5 is fitted with a winding drum 21.

[0049] The working principle and usage process of this utility model are as follows: After the cable stranding is completed, when the device drives the winding drum to wind up the stranded cable, the operator first places the shaft hole of the winding drum onto the outside of the mounting drum 5, and makes one end abut against the limiting plate 6 to form a preliminary positioning. Then, in order to further achieve the internal support and fixation of the winding drum, the double-threaded rod 10 can be rotated by the handle 13. When the double-threaded rod 10 does not need to be rotated, the handle 13 can be rotated to a horizontal state through the rotational relationship between it and the damping bearing seat 12, so that it does not hinder the installation and disassembly of the winding drum. When the double-threaded rod 10 needs to be rotated, it can be rotated to a perpendicular state with the double-threaded rod 10 through the damping bearing seat 12. The bidirectional threaded rod 10 can be rotated by turning the handle 13. The bidirectional threaded rod 10 has two threads in opposite directions, which are threadedly connected to the first threaded transmission sleeve 14 and the second threaded transmission sleeve 15, respectively. When the bidirectional threaded rod 10 rotates, the first threaded transmission sleeve 14 and the second threaded transmission sleeve 15 move towards each other under the drive, and each drives the first bearing seat 16 connected to its outer side to move towards each other. As the first bearing seats 16 on the left and right sides approach each other, the rotating arm 17 also rotates and unfolds outward. The other end of the rotating arm 17 is hinged to the second bearing seat 18. The inner support strip 19 fixedly connected to the outer side of the second bearing seat 18 moves outward under the drive of the rotating arm 17, gradually moving away from the mounting cylinder. 5. During this process, one end of the inner support strip 19 maintains a sliding connection with the second guide groove 9. Through the sliding connection and limiting of one end of the inner support strip 19 by the second guide groove 9, the first threaded transmission sleeve 14, the second threaded transmission sleeve 15, and the rotating arm can all maintain a stable state. The first threaded transmission sleeve 14 and the second threaded transmission sleeve 15 will not rotate with the rotation of the bidirectional threaded rod 10, nor will they wobble. The rotating arm 17 drives the inner support strip 19 to move outward through the second bearing seat 18, so that it fits tightly against the inner wall of the winding drum, and the friction is enhanced by the rubber pad 23. When the winding begins, the motor 4 drives the main shaft 3 to rotate, which can drive the mounting drum 5 along with the winding drum. The inner support bar 19 supports the rotating drum to wind up the cable after stranding. During the operation of the device, in order to prevent the first threaded transmission sleeve 14 and the second threaded transmission sleeve 15 from moving away from each other under high-frequency rotation or vibration, thereby causing the inner support structure to loosen, springs 20 are provided between the first threaded transmission sleeve 14 and the inner wall of the left end of the mounting cylinder 5, and between the second threaded transmission sleeve 15 and the sealing plate 7. The springs 20 are used to enhance the axial friction between the two sets of threaded pairs, namely the bidirectional threaded rod 10 and the first threaded transmission sleeve 14 and the second threaded transmission sleeve 15, thereby effectively improving the locking stability between the transmission sleeve and the bidirectional threaded rod 10, and ensuring that the inner support mechanism does not loosen or deviate unexpectedly during operation.After completing the winding operation of a spool, the double-threaded rod 10 is rotated in the opposite direction using the handle 13 to retract the inner support strip 19 towards the mounting cylinder 5, thus releasing the fixation on the spool 21. The handle 13 is then rotated back to a horizontal position to remove the spool 21, achieving quick installation and removal. In summary, this device, through its inner support mechanism that allows for rapid adjustment using the double-threaded rod and achieves efficient vibration resistance and anti-loosening function through spring friction enhancement design, enables rapid installation, secure tightening, and convenient disassembly of the spool. It boasts advantages such as simple structure, stable adjustment, strong clamping force, and no damage to the cylinder body. It is also suitable for spools with different inner diameter shaft holes, and is particularly suitable for efficient winding operations in the cable processing stranding machine process.
