The shaft seat 2 is arranged on the base 1, and the number of the shaft seats 2 is 2, which are respectively arranged at both ends of the long side direction of the base 1, maintaining a symmetrical arrangement in order to ensure the structural stability of the entire pay-off frame, Furthermore, it is convenient to erect the support shaft 4 on the two shaft seats 2 in the later stage, and the line connecting the corresponding positions of the two shaft seats 2 is parallel to the long side of the base 1, so that the support shaft 4 can be set to a larger length, so as to facilitate simultaneous A plurality of pay-off reels 3 are sequentially threaded on the support shaft 4 in series to realize the effect of simultaneous pay-off of multiple wire coils and improve the pay-off efficiency. The pay-off reel 3 is threaded on the support shaft 4 through the central hole 311. With the process of paying off, the relative rotation between the central hole 311 and the support shaft 4 can be formed, and the relative position between the support shaft 4 and the shaft seat 2 can also be realized. Rotation, the two positions here can be rotated, which ensures that the wire coil can rotate around the center point smoothly during the pay-off process, avoiding the phenomenon of jamming, and meeting the needs of smooth pay-off.

The two ends of the slotted hole 312 on the circular wire reel 31 are arranged as semicircles, mainly for the position that the stud 32 needs to be adjusted, so as to facilitate the realization of two extreme positions of the stud 32 in the slotted hole 312, ensuring When the stud 32 is at the extreme position, it does not interfere with the two ends of the slotted hole 312 , which affects the adjustment of the position of the stud 32 of the pay-off reel 3 . At the same time, the slotted hole 312 can also be replaced by more than 3 rows of holes 313, and the corresponding positions are arranged at the corresponding positions of the two pay-off reels 3, so that the holes 313 can be made corresponding to the common specifications of several wire coils that are frequently used in daily life. The position on the pay-off reel 3 is set, and when the stud 32 is locked later, the positioning and locking of the hole 313 can be more conveniently performed corresponding to wire holes of different diameters. The hole is preferably designed as a circle, for the smooth implementation of the threading of the stud 32 in the later stage. When in use, change the position of the stud 32 in the long slot hole 312 corresponding to the size of the central hole of the wire roll, and move the three studs 32 evenly arranged in the circumferential direction to the maximum diameter of the central hole of the wire, and pass through the stud. The screw threads at both ends of 32 cooperate with the nuts to lock the stud 32 at the largest distance from the center of the pay-off reel 3, thereby realizing strong support for the wire coil and ensuring that the wire coil can tightly embrace the stud 32 , to maintain the relative position stability between the two, so that in the later stage of the pay-off process, the wire coil can be smoothly paid off, and the wires are prevented from forming misaligned winding in the pay-off reel 3, which affects the pay-off speed and affects the Wire quality is adversely affected. During the use of the pay-off rack, the support shaft 4 needs to pass through multiple pay-off reels 3, and then the multiple pay-off reels 3 are strung together in a horizontal string, in order to enable the support shaft 4 to pass through multiple pay-off reels in turn conveniently 3’s center hole 311, the size of the center hole 311 needs to be designed to be larger than the diameter of the support shaft 4, so that the pay-off reel 3 can easily pass through the support shaft 4 of the shaft seat 2, and at the same time achieve a circular wire reel The central hole 311 of 3 can rotate around the support shaft 4 smoothly, so as to cooperate with the smooth unwinding operation of the wire coil, reduce the difficulty of workers' work, and improve work efficiency.

Preferably, a central bushing 33 is further included, and the central bushing 33 is rotatably matched with the support shaft 4 . In order to avoid the formation of dry friction between the central hole 311 on the circular wire reel 31 and the support shaft 4 and thus affect the service life of the circular wire reel 31, a central shaft sleeve 33 can be added, one end of the central shaft sleeve 33 and a circular wire reel 31 is fixedly connected, and the other end is locked by a stud 32, and the two circular wire reels 31 are in contact with the circular wire reels 31 on the other side. The setting of the central shaft sleeve 33 can not only avoid the dry friction between the central hole 311 and the support shaft 4, but also preliminarily position the central hole of the wire coil during the introduction of the wire coil, so as to facilitate the position when the stud 32 is inserted later. The adjustment is convenient for the fixed operation of the wire coil, which can effectively improve the work efficiency.

Preferably, the shaft seat 2 includes a movable shaft cover 21 .

When the movable shaft cover 21 is stuck with the shaft seat 2, that is, in the closed state, it is ensured that the support shaft 4 can be stably located inside the shaft seat 2, so as not to be caused by The excessive strength of the wire during unwinding causes the support shaft 4 to slip off from the shaft seat 2, or the sliding of the support shaft 4 due to the uneven road surface when moving the whole pay-off frame body. The shaft seat 2 is in the form of an upper opening, and the bottom is a semicircular concave structure, which facilitates the positional coordination between the shaft seat 2 and the support shaft 4, and ensures that the support shaft 4 can rotate smoothly in the concave structure, so as to Reduce the frictional resistance generated when the support shaft 4 and the shaft seat 2 rotate relative to each other, and speed up the rotation speed of the support shaft 4 in the concave structure of the shaft seat 2, so as to increase the pay-off speed and speed up the work efficiency of the operators.

Preferably, the one or more pay-off reels 3 are two or more pay-off reels 3 connected in series, and the support shaft 4 is rotatably matched with the central hole 311 or the central shaft sleeve 33 . The number of pay-off reels 3 is set in combination with on-site usage conditions. The pay-off rack can realize the function of using multiple pay-off reels 3 at the same time, and can realize the requirements of different speeds of multiple pay-off reels 3. Through the pay-off reel The central hole 311 on the 3 or the central shaft sleeve 33 and the support shaft 4 form a rotation fit, and each pay-off reel 3 can adopt different pay-off speeds to ensure smooth pay-off process, fast pay-off speed and high efficiency.

Preferably, a spacer 22 is arranged between the pay-off reels 3 . A plurality of pay-off reels 3 arranged in series on the support shaft 4 are spaced by bushings 22 to ensure that there is enough space between two adjacent pay-off reels 3 to avoid relative positional interference when they rotate. Cause the collision of pay-off reel 3, unsmooth pay-off, influence pay-off speed. The setting of spacer cover 22 then can avoid the mutual interference that produces when a plurality of pay-off reels 3 rotate, guarantees that no collision occurs between the pay-off reels 3 and the studs 32, and realizes the independent rotation of each pay-off reel 3, to adapt to the need for more In the case of separate pay-off at different pay-off speeds.

Preferably, the base 1 is a trolley. The base 1 can be set in a fixed form or in a movable form. It is designed to be movable in order to facilitate the movement of the entire pay-off frame, adjust the position and angle of the pay-off frame for different pay-off points, ensure smooth pay-off and increase pay-off speed.
