Description

Technical Field

[0001] The invention belongs to the field of cable auxiliary installation equipment, and in particular relates to a cable winding device. Background Art

[0002] During the cable winding process, if there is uneven arrangement, such as overlapping and winding of cables, the cable layers will be squeezed against each other, causing cable damage or uneven winding. In order to solve this problem, the cable winding device in the prior art has added a guide limit unit, which prevents the cable from being wound up during winding through the cooperation of the guide roller and the mounting block, and the use of the limit ear, thereby improving the neatness of the winding.

[0003] However, the existing winding adjustment devices all have the problem that the adjustment speed cannot match the cable winding speed. When the roller adjustment speed is faster than the cable winding speed, large gaps will appear between the cables, and they cannot be tightly wound; when the roller adjustment speed is too slow, the cables squeeze each other and overlap, which is a wire overlap defect. Summary of the invention

[0004] The purpose of the present invention is to overcome the above problems existing in the prior art and provide a cable winding device.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] A cable winding device, characterized by comprising:

[0007] A support seat, on which a magnetic ring is fixed;

[0008] a roller, the roller being rotatably connected to the support seat; and

[0009] Abutment members, several of which are slidably arranged in the mounting grooves on the peripheral side of the roller, and the abutment members move toward the axis of the roller after being pressed by the cable; a magnetic block is arranged at the end of the abutment member, and the magnetic block can be magnetically adsorbed with the magnetic ring.

[0010] Optionally, the support seat includes an axle seat, a support shaft is fixedly provided on the axle seat, and a support groove connected to the support shaft is formed on the roller.

[0011] Optionally, the magnetic block is connected to a contact switch; and the contact switch is arranged on the abutment member.

[0012] Optionally, the contact switch is arranged in a direction where the abutment member is away from the magnetic ring.

[0013] Optionally, the contact switch includes:

[0014] A switch sheet, wherein the switch sheet is slidably connected to the abutment member;

[0015] A switch slot, used for accommodating a switch sheet;

[0016] A switch moving piece and a switch fixed piece are provided between the switch slot and the switch piece; when the contact member is pressed by the cable, the switch moving piece is in electrical contact with the switch fixed piece.

[0017] Optionally, the magnetic block is rotatably disposed at the end of the abutment member.

[0018] Optionally, an abutment groove is formed at the end of the abutment member; a metal sheet that can be magnetically attracted to the magnetic block is fixed in the abutment groove, a rotating member is rotatably arranged in the abutment groove, and the magnetic block is fixed on the rotating member.

[0019] Optionally, the rotating member is connected to the abutment groove via a torsion spring.

[0020] The beneficial effects of the present invention are:

[0021] 1. Through the magnetic adsorption between the magnetic block and the magnetic ring, and the setting of the contact switch, the present application can automatically adjust the roller position according to the cable winding speed. This automatic adjustment mechanism ensures the tightness and uniformity of the cable winding. Since the roller position can be automatically adjusted according to the cable winding speed, manual intervention is reduced and the winding efficiency is improved.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0032] like Figure 1 The cable winding device shown in the figure comprises a support seat 1 and a roller 11 that rotates along the circumference of the support seat 1. The roller 11 is a circular cylinder; the two bottom surfaces of the roller 11 are respectively fixed with baffles 12 to prevent the cable from falling off. The support seat 1 comprises two symmetrically arranged shaft seats 13, the opposite inner sides of the two shaft seats 13 are respectively fixed with support shafts 14, and the two vertical surfaces of the roller 11 are respectively provided with support grooves 15 that can be connected to the support shaft 14. The axis of the roller 11 is provided with a through hole 16.

[0033] The end surface of one of the support shafts 14 is provided with a cylindrical magnetic ring 17, which is a permanent magnet. The magnetic ring 17 is slidably disposed in the through hole 16 along the axial direction of the roller 11. When the cable is wound, the roller 11 and the support shaft 14 maintain a relative rotation state; at the same time, the roller 11 moves along the axial direction of the support shaft 14 toward one end of the shaft seat 13, so that two adjacent turns of the cable wound on the roller 11 do not overlap each other.

[0034] A strip-shaped installation groove 18 is provided in the slide groove of the roller 11; the installation groove 18 penetrates the peripheral side wall of the roller 11 in the radial direction of the roller 11, and the extension direction of the installation groove 18 is arranged along the axial direction of the roller 11. A plurality of abutments 19 are evenly distributed in the installation groove 18 along the axial direction of the roller 11, and the abutments 19 are slidably arranged in the installation groove 18 along the radial direction of the roller 11. Preferably, two adjacent abutments 19 are arranged to fit each other, and the length of the abutments 19 along the axial direction of the roller 11 is equivalent to the diameter of the cable, so that when the cable is wound around the side of the support seat 1, a single abutment 19 can be pressed to move toward the axial center direction of the roller 11. A dovetail block is arranged in the installation groove 18 to prevent the abutment 19 from falling off.

[0035] The end of the abutment 19 facing the axis of the roller 11 is rotatably provided with a magnetic block 2, which is an electromagnet. A switch slot 21 is provided on the side wall of the abutment 19, and a switch sheet 22 is provided in the switch slot 21 to slide along the axial direction of the roller 11. A switch movable sheet and a switch fixed sheet are provided between the switch slot 21 and the switch sheet 22, and the switch movable sheet and the switch fixed sheet are electrically connected to the power supply and the magnetic block 2 respectively. When the switch sheet 22 is received in the switch slot 21, the switch movable sheet is electrically separated from the switch fixed sheet, otherwise the switch movable sheet is in contact with the switch fixed sheet. A compression spring is fixed in the switch slot 21, and the compression spring is fixedly connected to the switch sheet 22, and is used to push the switch sheet 22 to return to the outside of the switch slot 21.

[0036] In one embodiment, the switch slot 21 is provided on the side wall of the abutment member 19 facing away from the magnetic ring 17. After the abutment member 191 is pressed downward by the cable, the adjacent abutment member 192 on the side of the abutment member 191 facing the magnetic ring 17 is located at the same height as the abutment member 191, and the adjacent abutment member 193 on the side of the abutment member 191 facing away from the magnetic ring 17 is not pressed and remains in place. After the abutment member 191 is pressed, the switch piece 22 on the side facing away from the magnetic ring 17 is separated from the adjacent abutment member 193, and extends out of the switch slot 21 under the action of the reset spring, so that the switch movable piece contacts the switch fixed piece; at the same time, the adjacent abutment member 192 on the side of the abutment member 191 facing the magnetic ring 17 is received in the switch slot 21 due to the pressing action of the abutment member 191, and the switch movable piece is separated from the switch fixed piece. The magnetic block 2 of the abutment 191 is energized, and the magnetic block 2 of the abutment 192 is de-energized; since the abutment 193 does not move, the switch piece 22 in the abutment 193 is still pressed by the abutment 194 on the side of the abutment 193 away from the magnetic ring 17 and is retracted into the switch slot 21, and the magnetic block 2 of the abutment 193 is de-energized. The top corner of the switch piece 22 is chamfered.

[0037] After the magnetic block 2 of the abutment 19 is energized, the roller 11 moves toward the magnetic ring 17 due to the magnetic attraction between the magnetic block 2 and the magnetic ring 17. Specifically, by setting the position of the abutment 19 on the roller 11, after the cable contacts the abutment 19, the cable can be wound on the adjacent winding track during the roller 11 moving along its own axial direction.

[0038] In order to avoid interference of the magnetic block 2 facing the magnetic ring 17 with the movement of the roller 11 during the movement of the roller 11, the magnetic block 2 and the abutment member 19 are in a rotational connection relationship. Specifically, an abutment groove 23 is provided at the end of the abutment member 19 facing the axis of the roller 11, and a rotating member 24 is rotatably arranged in the abutment groove 23; the longitudinal section of the rotating member 24 is fan-shaped, and the abutment groove 23 is a fan-shaped groove, and the central angle of the abutment groove 23 is greater than the central angle of the rotating member 24, so that the rotating member 24 can rotate freely in the abutment groove 23. The magnetic block 2 is fixed on the plane of the rotating member 24 facing the magnetic ring 17. The inner wall of the abutment groove 23 facing the magnetic ring 17 is arranged along the height direction of the abutment groove 23, and a metal sheet is fixed on the side wall of the abutment groove 23 facing the magnetic ring 17. When the magnet block 2 is powered on, the magnet block 2 rotates toward the magnetic ring 17 by adsorbing the metal sheet, and the lower edge of the side wall of the rotating member 24 toward the magnetic ring 17 extends out of the abutment groove 23, and generates an adsorption effect with the magnetic ring 17. The rotating member 24 is coaxially provided with a torsion spring on the connecting shaft of the abutment groove 23, which is used to drive the rotating member 24 to reset in a direction away from the magnetic ring 17; when the magnet block 2 is powered off, the rotating member 24 is reset under the action of the torsion spring, so that the rotating member 24 is retracted into the abutment groove 23.

[0039] In one embodiment, the central angle of the abutting groove 23 is 120°, and the central angle of the rotating member 24 is 75°.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
