Description

Technical Field

[0001] This utility model relates to the field of threading machine reel technology, specifically a reel structure with anti-reverse function. Background Technology

[0002] In modern building installation projects, it is necessary to thread pipes. In addition to manual threading, threading machines can be used to automatically thread the pipes to improve threading efficiency. Usually, as the guide wheel sends the wire out or pulls it back, the spool rotates around its central axis, thus ensuring that the wire can be smoothly led out or retrieved from the spool.

[0003] Utility model application number 202020104799.X discloses a wire reel structure, comprising an upper wire reel and a lower wire reel that are spliced ​​and fixed together, and also includes a wire inlet tube. The lower wire reel has a wire inlet concentrically located at its bottom, and the upper wire reel has a guide post at its center. The upper and lower sides of the guide post are connected to a rotating fixed shaft via bearings, and the opening of the wire inlet tube is eccentrically located at the edge of the guide post.

[0004] In the aforementioned patent documents, the coil does not have an anti-reverse mechanism. When the lead wire is fed out or retracted too quickly, the coil will rotate rapidly. When the machine stops, the coil will continue to rotate at a certain angle due to inertia, maintaining its original motion pattern. Later, due to the compression of the lead wire, it will reverse at a certain angle. During this process, the lead wire is easily squeezed out of the coil, thus affecting the normal use of the machine. Therefore, a coil structure with an anti-reverse function is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a reel structure with anti-reverse function to solve the problem that when the lead wire is fed out or retracted too quickly, the reel will rotate rapidly. When the machine stops, the reel will continue to rotate at a certain angle due to inertia, and then reverse at a certain angle due to the compression of the lead wire. During this process, the lead wire is easily squeezed out of the reel, thus affecting the normal use of the machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A reel structure with anti-reverse function includes a lower reel and an upper reel. The upper reel is positioned on top of the lower reel, and a rubber pad is fixedly mounted on the top of the lower reel. The bottom of the upper reel is installed with the lower reel and the rubber pad. The bottom of the upper reel is threadedly fitted with a mounting stud. A fixed shaft is slidably mounted inside the upper reel. A lower shaft sleeve is installed between the bottom of the upper reel and the inner side of the fixed shaft. An upper shaft sleeve is installed between the top of the upper reel and the inner side of the fixed shaft. A shaft block is fixedly mounted on the top of the fixed shaft. A buffer spring is installed inside a groove on the top of the upper reel, and a ball is mounted on the top of the buffer spring. The top of the upper reel, the top of the fixed shaft, and the top of the upper shaft sleeve are in contact with the bottom of a resistance plate. A hexagonal fastener is provided on the top of the resistance plate.

[0008] Preferably, the bottom of the resistance plate is provided with a plurality of recessed holes, and the top of the sphere is installed in the recessed holes provided at the bottom of the resistance plate.

[0009] Preferably, the vertical central axes of the lower reel, fixed shaft, lower bushing, and upper bushing are arranged to coincide.

[0010] Preferably, the inner wall of the lower wire reel is symmetrically and fixedly provided with a number of lower ribs, and the inner wall of the upper wire reel is symmetrically and fixedly provided with a number of upper ribs.

[0011] Preferably, the hexagonal fastener is internally threaded to the outer side of the shaft block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, a buffer spring is installed inside the groove at the top of the upper reel, and a ball is installed at the top of the buffer spring. The top of the upper reel, the top of the fixed shaft, the top of the upper bushing, and the bottom of the resistance plate are in contact. The hexagonal fastener is threaded to the outer side of the shaft block. When the lead wire is fed out or retracted too quickly, the ball continuously squeezes against the bottom recess and bottom plane of the resistance plate as the upper and lower reels rotate, thereby generating resistance to the upper and lower reels and preventing them from reversing. When the machine stops, the reels will quickly stop rotating. During this process, the lead wire is not easily squeezed out of the reel, maintaining the normal operation of the machine.
