Description

Technical Field

[0001] This utility model relates to the field of guide wheel technology, specifically a guide wheel mechanism for drawbows. Background Technology

[0002] The wire bundler is a key component in a wire bundling machine. With the continuous development of cable technology, the wire bundler now uses guide wheels instead of ceramic eyelets, changing from sliding friction to rolling friction, which greatly reduces friction and extends service life.

[0003] In response, Chinese patent application number CN202223330254.9 discloses a guide wheel mechanism for a drawbow, including a mounting base and guide wheels. The guide wheels are spaced apart and mounted above the mounting base. An adjustment component is mounted on the upper surface of the mounting base, and vertical plates are symmetrically mounted on the upper surface of the adjustment component. The vertical plates are connected to the output end of the adjustment component. A guide component is mounted on the inner wall of the vertical plates, and the guide wheels are correspondingly mounted between the two vertical plates. This utility model uses the guide component to guide the rotation of the guide wheels, ensuring stability during rotation, reducing friction, and extending the service life of the guide wheels. Simultaneously, the adjustment component mounted on the mounting base allows for quick adjustment of the distance between the two vertical plates, enabling installation of guide wheels of different sizes. This provides a wide range of adaptability, eliminates the need to change the mounting base, reduces overall installation costs, facilitates assembly and debugging, and offers flexibility.

[0004] The guide wheel can be quickly installed with two sets of vertical plates that can move in opposite directions. However, in the actual production process, the friction between the wire and the guide wheel only exists on the groove surface of the guide wheel. Since the guide wheel is a one-piece structure, it needs to be replaced as a whole when replacing it. Moreover, multiple guide wheels on the same bow need to be replaced together, which increases the replacement cost and is not conducive to improving the economic benefits of the enterprise.

[0005] Therefore, in order to solve the above problems, a guide wheel mechanism for drawbows is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a guide wheel mechanism for a drawbow, in order to solve the problem mentioned in the background art that the guide wheel in the prior art can be quickly installed with guide wheels of different sizes by setting two sets of vertical plates that can move in opposite directions. However, in the actual production process, the friction between the wire and the guide wheel only exists on the groove surface of the guide wheel. Since the guide wheel is a one-piece structure, it is necessary to replace the entire guide wheel when replacing it, and multiple guide wheels on the same drawbow need to be replaced together, which increases the replacement cost and is not conducive to improving the economic benefits of enterprises.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a guide wheel mechanism for a drawbow, comprising: a mounting plate, wherein vertical plates are mounted on both ends of the top surface of the mounting plate; A rotating structure is installed on the vertical plate. The rotating structure includes a rotating shaft, which is movably mounted on the upper inner side of the vertical plate via bearings. A rectangular block is integrally formed in the middle of the rotating shaft. Two sets of discs are integrally formed on both sides of the middle of the rotating shaft. Cross-shaped through grooves are integrally formed on both sides of the middle of the rotating shaft. Two sets of guide wheel blocks are sleeved on the outer side of the middle of the rotating shaft. A rectangular groove is opened in the middle of the inner sidewall of the guide wheel block. A through hole is opened on the outer surface of the guide wheel block. A screw is inserted into the inner side of the through hole. A nut is threaded to the outer side of the end of the screw.

[0008] Preferably, the mounting plate is equipped with a partition structure, the partition structure including a fixing block, the fixing block being fixedly installed in the middle of the top surface of the mounting plate, and the top surface of the fixing block having an arc groove.

[0009] Preferably, the disc is located inside the vertical plate, the guide wheel block is located between the two sets of discs, and the rectangular groove is engaged on the outside of the rectangular block.

[0010] Preferably, the two sets of guide wheel blocks are fitted together, and the through hole communicates with the interior of the cross through groove.

[0011] Preferably, the screw passes through the cross groove and the through holes on the two sets of guide wheel blocks, and the nut is engaged inside the through hole.

[0012] Preferably, the fixing block is located on the lower side of the guide wheel block, and the arc groove is adapted to the outer wall of the guide wheel block.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by setting a detachable guide wheel block on the outside of the rotating shaft, the guide wheel block contacts the wire material, and when the guide wheel block wears out, the guide wheel block can be replaced separately without replacing the rotating shaft, which reduces the operating cost of the mechanism and makes the mechanism more practical.

[0014] 1. This utility model features a rotating structure. During installation, two sets of guide wheel blocks are placed on either side of the center of the rotating shaft. The guide wheel blocks are secured to the outside of the rectangular block via rectangular slots, aligning the two sets of guide wheel blocks. At this point, the through hole communicates with the interior of the cross slot. A nut is inserted into the through hole, and the screw is rotated. The screw connects threadedly to the nut, thus fixing the two sets of guide wheel blocks together, facilitating convenient installation. When the surface of the guide wheel blocks wears, the screw is rotated in the opposite direction, allowing it to be removed from the through hole, releasing the fixation between the two sets of guide wheel blocks. This allows the two sets of guide wheel blocks to be removed from the rotating shaft for individual replacement, while the rotating shaft and disc can continue to be used, reducing replacement costs and improving the practicality of the mechanism.

[0015] 2. This utility model has a partition structure, with the guide wheel block located on the upper side of the fixed block. In use, the guide wheel block, in conjunction with the arc groove, can guide the wire. The fixed block can prevent the wire from contacting the mounting plate and causing wear, thus keeping the wire intact. Attached Figure Description
