The application is simple to operate, and the limit sleeve and the positioning block can improve the limiting effect of the connecting shaft inside the support ring to avoid the deviation caused by the rotation of the wire roller during the pay-off process. The limit sleeve and the positioning block can be disassembled to facilitate the placement and removal of the wire roller; the application has a reasonable structure, the fixed rod and the connecting plate can support the bottom of the support plate to ensure the stable placement and use of the bottom of the pay-off frame, and the first clamping plate and the second clamping plate can brake the wire roller to shorten the length of the cable released by the wire roller due to inertial rotation.

[0004] However, although a pay-off stand in the above technology can play a guiding role through the support plate on the bottom end, since the two sets of clamping plates are fixed on the support plate and the position is fixed, it can only have a good guiding effect on wire rollers of the same specification and size, making the adaptability poor; therefore, a pay-off stand guide wheel is proposed to address the above problem. Utility Model Content

[0024] When working, a pay-off stand in the above technology can play a guiding role through the support plate on the bottom end, but because the two sets of clamping plates are fixed on the support plate and the position is fixed, it can only have a good guiding effect on the wire rollers of the same specification and size, making the adaptability poor. The structural design of the guide mechanism realizes the function of facilitating the guidance of the pay-off drum 20. When the pay-off drum 20 is placed on the fixed rod 21 and rotated, the left and right sides of the pay-off drum 20 keep in contact with the guide wheel body 24, so as to limit the range of left and right movement of the pay-off drum 20 on the pay-off stand body 1, and avoid the pay-off drum 20 on the pay-off stand body 1, so as to guide the pay-off reel 20, and the first fixing plate 23 and the second fixing plate 25 are also fixed with a fixing block 26 for connecting with the plug post 28. When a larger-sized pay-off reel 20 is placed, the connecting rod 31 moves on the long block 32 and stretches the second spring 33 to adapt to the larger-sized pay-off reel 20, while also ensuring that the guide wheel body 24 can keep in contact with the pay-off reel 20, wherein the bottom ends of the first fixing plate 23 and the second fixing plate 25 are rotatably connected together, so as to facilitate the first fixing plate 23 and the second fixing plate 25 to be sleeved and installed on the fixing rod 21.

[0025] Furthermore, a receiving groove 30 is formed on the connecting rod 31, and the size of the receiving groove 30 is adapted to the first spring 29 so as to receive the first spring 29, and the connecting rod 31 is in contact with the plug post 28;

[0026] During operation, through the structural design of the first spring 29 and the receiving groove 30, when inserting the column 28 into the slot 27, it is only necessary to pull the column 28 outward to pull out the first spring 29 inside the receiving groove 30, and the column 28 can be inserted into the slot 27 by bending the first spring 29, so as to facilitate the connection between the column 28 and the fixed block 26. Similarly, it is also convenient to release the connection between the column 28 and the fixed block 26. The first spring 29 is stored in the receiving groove 30. By pulling the first spring 29 out of the receiving groove 30, the column 28 can be connected to the fixed block 26 or the connection between the column 28 and the fixed block 26 can be released through the deformation of the first spring 29.

[0027] Furthermore, a gasket 40 is glued and fixed on the inner wall of the slot 27, and the gasket 40 is made of rubber;

[0028] When working, the gasket 40 is made of rubber material and is used to increase the friction between the inner wall of the slot 27 and the plug post 28 to facilitate the connection between the plug post 28 and the fixing block 26. At the same time, when the connection between the plug post 28 and the fixing block 26 is released, the gasket 40 can also play a buffering role to avoid greater wear.

[0029] Furthermore, a slider 34 is welded and fixed on the inner wall of the first fixing plate 23 and the second fixing plate 25. The slider 34 is slidably connected inside the slide groove 35. The size of the slide groove 35 is slightly larger than the slider 34 to ensure that the slider 34 can be inserted into the slide groove 35. The slide groove 35 is provided on the fixing rod 21.

[0030] During operation, the slider 34 slides in the slide groove 35 to limit the movement of the first fixing plate 23 and the second fixing plate 25 on the fixing rod 21 , ensuring that the first fixing plate 23 and the second fixing plate 25 can only move horizontally along the direction of the fixing rod 21 .

[0031] Furthermore, a mounting groove 37 is provided on the second fixing plate 25, a mounting block 36 is inserted inside the mounting groove 37, both the mounting block 36 and the mounting groove 37 are designed in an arc shape, a pull rod 39 is inserted on the mounting block 36, a third spring 38 is sleeved on the pull rod 39, and the bottom end of the third spring 38 is fixed to the second fixing plate 25 by welding;

[0032] During operation, since the first fixing plate 23 and the second fixing plate 25 are rotatably connected, when the first fixing plate 23 and the second fixing plate 25 are spliced ​​together, the mounting block 36 fixed on the first fixing plate 23 will be inserted into the mounting groove 37, and then the first fixing plate 23 and the second fixing plate 25 can be connected together by fixing them through the pull rod 39. Similarly, the pull rod 39 can be released from the fixation of the mounting block 36 by the pull rod 39 only by pulling it upwards.

[0033] Furthermore, six groups of guide wheel bodies 24 are provided, and the six groups of guide wheel bodies 24 are circumferentially distributed on the first fixing plate 23 and the second fixing plate 25;

[0034] During operation, three groups of guide wheel bodies 24 are respectively provided on the first fixed plate 23 and the second fixed plate 25. The guide wheel bodies 24 keep in contact with the pay-off drum 20. The six groups of guide wheel bodies 24 are designed to be distributed in a circular shape. During the rotation of the pay-off drum 20, the first fixed plate 23 and the second fixed plate 25 can remain stable without causing large shaking.

[0035] Working principle: A wire pay-off stand in the prior art can play a guiding role through the support plate on the bottom, but because the two sets of clamping plates are fixed on the support plate and the position is fixed, it can only have a good guiding effect on the wire rollers of the same specification and size, making the adaptability poor. A wire pay-off stand guide wheel in this case realizes the function of facilitating the guidance of the wire pay-off drum 20 through the structural design of the guide mechanism. When the wire pay-off drum 20 is placed on the fixed rod 21 and rotated, the left and right sides of the wire pay-off drum 20 keep in contact with the guide wheel body 24, so as to limit the range of left and right movement of the wire pay-off drum 20 on the wire pay-off stand body 1, and avoid the wire pay-off drum 20 from moving left and right on the wire pay-off stand body 1. 0 is offset on the pay-off frame body 1 to guide the pay-off reel 20, and the first fixing plate 23 and the second fixing plate 25 are also fixed with a fixing block 26 for connecting with the plug post 28. When a larger-sized pay-off reel 20 is placed, the connecting rod 31 moves on the long block 32 and stretches the second spring 33 to adapt to the larger-sized pay-off reel 20, while also ensuring that the guide wheel body 24 can maintain contact with the pay-off reel 20, wherein the bottom ends of the first fixing plate 23 and the second fixing plate 25 are rotatably connected together to facilitate the first fixing plate 23 and the second fixing plate 25 to be sleeved and installed on the fixing rod 21.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
