[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] like Figures 1 to 7As shown, the adjustable pay-off rack device of the present invention includes: a ground rail 1, a mobile frame 2, and a pay-off shaft assembly 3; the mobile frame 2 is L-shaped or T-shaped, a pair of pay-off shaft assemblies 3 are fixedly mounted on the side of the mobile frame 2, and the mobile frame 2 has two rows of mounting holes so that the pay-off shaft assembly 3 can be adjusted up and down; at the same time, the bottom of the mobile frame 2 is slidably connected to the ground rail 1 and can move along the axial direction of the pay-off shaft on the pay-off shaft assembly 3.

[0030] Specifically, if Figure 3 As shown, the floor rail 1 is fixed to the installation ground by two floor rail side plates 11 through dowel holes. Four open bearing seats 13 are slidably inserted from both ends of the support rail linear bearings 12 through internal bearings. The floor rail side plates 11 and the two support rail linear bearings 12 are locked at both ends by screws. The open bearing seats 13 can slide on the support rail linear bearings 12 to drive the mobile frame 2 to move on the support rail linear bearings 12. The open bearing seats 13 are fixed to the frame connecting block 21 by fixing screws, allowing the mobile frame 2 to slide on the support rail linear bearings 12 following the open bearing seats 13.

[0031] like Figure 4 As shown, the mobile frame 2 is L-shaped or T-shaped, and is welded together by a frame connecting block 21, two cold-bent hollow square steel bars 24, two foot support plates 25, and two adjustable notched cold-bent hollow square steel bars 26, forming the main frame system. Four bearing-fixing side plates 23 and two brake fixing brackets 22 are fixed to the adjustable notched cold-bent hollow square steel bars 26 via screws through four corner threaded holes. The adjustable notched cold-bent hollow square steel bars 26 are provided with two rows of mounting holes. The bearing-fixing side plates 23 and the brake fixing brackets 22 can be selectively mounted on the adjustable notched cold-bent hollow square steel bars 26 to adjust the vertical position of the pay-off shaft assembly 3.

[0032] like Figure 5 As shown, the pay-off shaft assembly 3 is composed of a pneumatic butterfly brake 31, a brake disc 32, a connecting ring 33, a square seat bearing 34, a conical seat 35, a conical locking nut 37, and a pay-off shaft 36; the pneumatic butterfly brake 31 is connected to the brake fixing frame 22 by a perforated screw, and is clamped to the brake disc 32 by an internal pneumatic brake pad to achieve the braking purpose; the brake disc 32 is fixed to the pay-off shaft 36 through a transition of the connecting ring 33, and is fixed to the movable frame 2 by two square seat bearings 34 through the bearing fixing side plate 23.

[0033] like Figure 6 、 Figure 7 As shown, the internal bearing 341 with the square seat bearing 34 achieves the effect of rotation with the pay-off shaft 36; the conical seat 35 and the conical locking nut 37 are fixed to the square slot 361 of the pay-off shaft 36 through the locating pin to achieve a circumferential fixing effect.

[0034] The working principle and working process of the adjustable pay-off stand device of the present invention are briefly described below.

[0035] 1. Adjustable notch There are notches on the cold-bent hollow square steel that can be adjusted up and down to fix the shaft. The installation height and number of shafts can be adjusted according to the product winding specifications, size, quantity, etc., thereby solving the problem of fixed pay-off equipment that cannot be adjusted in height and multiple wires can be wound together.

[0036] 2. During the operation of current fixed pay-off equipment, the entire winding structure is in a fixed state, and angle deviations can occur during the pay-off process, leading to inconsistent winding tension, poor winding uniformity, and operator fatigue. The adjustable pay-off equipment uses rail-mounted linear bearings with open bearing seats fixed to the frame, allowing the frame structure to slide on the rails. During the pay-off process, the pay-off position is automatically adjusted according to the wire output direction, ensuring that the pay-off angle and winding angle are always 90 degrees perpendicular, avoiding uneven tension caused by angle deviations.

[0037] The utility model discloses an adjustable pay-off stand device which changes a fixed pay-off mode and changes a pay-off mechanism from a fixed type to an adjustable type. The movable range is adjustable from 0 to 800 mm according to actual use conditions.

[0038] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
