Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to an anti-tangle guide wheel device for cable production. Background Technology

[0002] A cable is an electrical wire made of one or more mutually insulated conductors and an outer insulating protective layer, used to transmit electrical energy or signals. It features good insulation, high conductivity, high mechanical strength, and corrosion resistance, and is widely used in power, communication, and construction industries. During production, cables need to be wound onto a reel.

[0003] Currently, when cables are wound up, a reciprocating translation mechanism drives a guide wheel device to guide the cable, so that the cable can be wound evenly on the drum layer by layer to prevent tangling. However, the tension of the cable is unstable during the winding process, which can easily cause the cable to become loose and scattered after winding, thus affecting the winding effect. Utility Model Content

[0004] The purpose of this invention is to provide an anti-tangle guide wheel device for cable production, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] An anti-tangle guide wheel device for cable production includes a U-shaped frame. A lower guide wheel is rotatably mounted inside the lower part of the U-shaped frame via a first rotating shaft, with both ends of the first rotating shaft extending to the outside of the U-shaped frame. A U-shaped block is mounted inside the upper part of the U-shaped frame via a lifting mechanism, and an upper guide wheel is rotatably mounted inside the U-shaped block via a second rotating shaft. Annular push blocks are mounted on the outer surfaces of both ends of the first rotating shaft via a translation mechanism, and annular friction blocks are mounted on the outer surfaces of the annular push blocks via an elastic connection mechanism.

[0007] As can be seen, by using the lifting mechanism to drive the upper guide wheel to descend, the cable is clamped between the upper and lower guide wheels. Then, the translation mechanism and the elastic connection mechanism drive the annular friction block to press against the outer surface of the U-shaped frame, thereby increasing the resistance when the first rotating shaft rotates and adjusting the resistance. Therefore, during the cable winding process, the cable can be kept in a taut state, so that it can be tightly wound on the drum, avoiding looseness and improving the winding effect.

[0008] Furthermore, the lifting mechanism includes a first screw rotatably mounted on the upper surface of the U-shaped block, the upper end of the first screw penetrating to the upper side of the U-shaped frame and threadedly connected thereto. Guide posts are connected to both sides of the upper surface of the U-shaped block, and the upper ends of the guide posts slide through to the upper side of the U-shaped frame.

[0009] Furthermore, the translation mechanism includes a cross groove formed inside the first rotating shaft, a cross block installed inside the cross groove, and all four ends of the cross block connected to the inner wall of the annular push block. A second screw is rotatably installed inside the cross groove, the second screw passing through the interior of the cross block and threadedly connected to it.

[0010] Furthermore, the elastic connection mechanism includes a telescopic rod installed on the outer surface of the annular push block, the end of the telescopic rod being connected to the annular friction block, and a spring being sleeved on the outer surface of the telescopic rod, with both ends of the spring abutting against the annular push block and the annular friction block respectively.

[0011] Furthermore, the end of the second screw extends to the outside of the first rotating shaft and is fitted with a torsion block. A bolt is installed inside the torsion block, and the end of the first rotating shaft has a ring array of multiple screw holes that are compatible with the bolts.

[0012] Furthermore, both the lower and upper guide wheels have silicone pads on their curved guide surfaces, and the outer surface of the silicone pads has anti-slip textures.

[0013] Furthermore, there are four sets of elastic connection mechanisms, and the four sets of elastic connection mechanisms are distributed in a ring array.

[0014] Furthermore, a knob is installed on the top of the first screw, and the outer surface of the knob is provided with anti-slip protrusions.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model uses a lifting mechanism to drive the upper guide wheel to descend, clamping the cable between the upper and lower guide wheels. Then, a translation mechanism and an elastic connection mechanism are used to drive the annular friction block to press against the outer surface of the U-shaped frame, thereby increasing the resistance when the first rotating shaft rotates. The resistance can be adjusted, thus ensuring that the cable is in a taut state during the cable winding process, allowing it to be tightly wound on the drum, avoiding looseness and improving the winding effect.

[0017] 2. By screwing the bolt into the corresponding screw hole, the angle of the second screw can be locked, preventing the second screw from loosening due to prolonged rotation of the first shaft and causing a change in the resistance of the first shaft. This ensures the consistency of cable tension and further improves the winding effect. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides an anti-tangle guide wheel device for cable production, including a U-shaped frame 100. A lower guide wheel 102 is rotatably mounted inside the lower part of the U-shaped frame 100 via a first rotating shaft 101, with both ends of the first rotating shaft 101 extending to the outer side of the U-shaped frame 100. A U-shaped block 103 is mounted inside the upper part of the U-shaped frame 100 via a lifting mechanism 200. An upper guide wheel 105 is rotatably mounted inside the U-shaped block 103 via a second rotating shaft 104. Annular push blocks 106 are mounted on the outer surfaces of both ends of the first rotating shaft 101 via a translation mechanism 300. Annular friction blocks 107 are mounted on the outer surfaces of the annular push blocks 106 via an elastic connecting mechanism 400.

[0026] In use, the U-shaped frame 100 is installed on the reciprocating moving mechanism. Then, the cable is passed between the lower guide wheel 102 and the upper guide wheel 105 and connected to the drum. Then, the lifting mechanism 200 is used to drive the upper guide wheel 105 to descend, so that the cable is clamped between the upper guide wheel 105 and the lower guide wheel 102, reducing the possibility of the cable slipping between the upper guide wheel 105 and the lower guide wheel 102.

[0027] Then, through the combined action of the translation mechanism 300 and the elastic connection mechanism 400, the annular friction block 107 is driven to abut against the outer surface of the U-shaped frame 100. Therefore, when the first rotating shaft 101 rotates, it will be subject to friction between the annular friction block 107 and the U-shaped frame 100, thereby increasing the resistance of the first rotating shaft 101. Only when the cable is subjected to a certain tension can the first rotating shaft 101 be driven to rotate, thus ensuring that the cable is in a taut state, so that it can be tightly wound on the drum, avoiding looseness and scrambling, and improving the winding effect.

[0028] Furthermore, by adjusting the force applied by the annular pusher 106 to the annular friction block 107, the magnitude of the resistance can also be adjusted, providing high flexibility.

[0029] Preferably, the lifting mechanism 200 includes a first screw 201 rotatably mounted on the upper surface of the U-shaped block 103, the upper end of the first screw 201 extending through to the upper side of the U-shaped frame 100 and threadedly connected thereto. Guide posts 202 are connected to both sides of the upper surface of the U-shaped block 103, and the upper ends of the guide posts 202 slide through to the upper side of the U-shaped frame 100.

[0030] Because the U-shaped block 103 is limited by the two guide posts 202, it can only move in the vertical direction. Therefore, when the first screw 201 is rotated, the U-shaped block 103 can be driven to move vertically up and down under the action of the threaded connection.

[0031] Preferably, the translation mechanism 300 includes a cross groove 301 formed inside the first rotating shaft 101. A cross block 302 is installed inside the cross groove 301, and all four ends of the cross block 302 are connected to the inner wall of the annular push block 106. A second screw 303 is rotatably installed inside the cross groove 301, and the second screw 303 passes through the interior of the cross block 302 and is threadedly connected to it.

[0032] Since the inner wall of the cross groove 301 limits the cross block 302, when the second screw 303 is turned, the cross block 302 can be moved along the length of the second screw 303, and the annular push block 106 can be moved.

[0033] Preferably, the elastic connection mechanism 400 includes a telescopic rod 401 installed on the outer surface of the annular push block 106. The end of the telescopic rod 401 is connected to the annular friction block 107. A spring 402 is sleeved on the outer surface of the telescopic rod 401. The two ends of the spring 402 abut against the annular push block 106 and the annular friction block 107, respectively.

[0034] When the annular push block 106 approaches the annular friction block 107, it causes the telescopic rod 401 and the spring 402 to contract synchronously. When the spring 402 contracts, it increases the elastic force applied to the annular friction block 107. When the first rotating shaft 101 rotates, it drives the annular friction block 107 to rotate through the annular push block 106 and the telescopic rod 401. Due to the relative friction between the annular friction block 107 and the U-shaped frame 100, the resistance when the first rotating shaft 101 rotates is increased. Furthermore, the closer the annular push block 106 is to the annular friction block 107, the greater the contraction of the spring 402, which in turn increases the resistance when the first rotating shaft 101 rotates, thus achieving the purpose of adjustment.

[0035] Preferably, the end of the second screw 303 extends to the outside of the first rotating shaft 101 and is fitted with a torsion block 500. A bolt 501 is installed inside the torsion block 500. The end of the first rotating shaft 101 is provided with a plurality of screw holes 502 in an annular array that are adapted to the bolts 501.

[0036] By screwing the bolt 501 into the corresponding screw hole 502, the angle of the second screw 303 can be locked, preventing the second screw 303 from loosening due to prolonged rotation of the first shaft 101 and causing a change in the resistance of the first shaft 101. This ensures the consistency of cable tension and further improves the winding effect.

[0037] Preferably, both the lower guide wheel 102 and the upper guide wheel 105 have silicone pads on their arc-shaped guide surfaces, and the outer surface of the silicone pads has anti-slip textures.

[0038] The use of silicone pads and anti-slip textures further increases the friction between the cable and the upper guide wheel 105 and the lower guide wheel 102, preventing the cable from slipping between them and ensuring the cable tension.

[0039] Preferably, four sets of elastic connection mechanisms 400 are provided, and the four sets of elastic connection mechanisms 400 are distributed in a circular array.

[0040] By setting up four sets of elastic connection mechanisms 400, the connection between the annular friction block 107 and the annular push block 106 is made more solid and stable, and the contact surface between the annular friction block 107 and the U-shaped frame 100 is subjected to more uniform force, thus avoiding local wear.

[0041] Preferably, a knob is installed on the top of the first screw 201, and the outer surface of the knob is provided with anti-slip protrusions.

[0042] The knob and anti-slip protrusions make it easy to turn the first screw 201 to drive the upper guide wheel 105 down, and reduce the chance of slipping, ensuring that the upper guide wheel 105 clamps the cable.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
