[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0025] The utility model aims to provide a wire pay-off rack for wiring electric blankets, wherein the wire reel can be rotated under the drive of a second motor, and the wire reel is driven and controlled by the first motor and the second motor through monitoring the first slider and the second slider.

[0026] The utility model discloses a wire pay-off frame for wiring electric blanket, comprising a base 1, a first support shell 2, a guide assembly, a rotating assembly and a wire pay-off assembly, such as Figure 1 , Figure 2 , Figure 3 shown.

[0027] The base 1 is used to support the guide assembly, the rotating assembly, and the pay-off assembly. A movable universal wheel with a brake (not shown in the figure) can be provided on the base 1 so that the pay-off frame can be moved as needed.

[0028] The rotating assembly is used to drive the wire, and the rotating assembly includes a first motor, two rotating shafts and two driving wheels 3; the two rotating shafts are arranged on the first supporting shell 2, and are respectively connected to the first motor arranged in the first supporting shell 8 through connecting pieces; the connecting pieces can be existing ones. A detachable driving wheel 3 is arranged on the rotating shaft; the distance between the two driving wheels 3 is smaller than the diameter of the wire, so that the first motor drives the driving wheel 3 to rotate, and the two driving wheels 3 move with the wire, such as Figure 1 The first motor is arranged in the first supporting shell 2.

[0029] The guide assembly is used for guiding, and comprises a first vertical guide part and a second vertical guide part, and the rotating assembly is located between the first guide part and the second guide part.

[0030] The first guide part includes a first guide rod 4 with a first slider 6, one end of the first guide rod 4 is arranged on the base 1, and the other end is arranged on the first support shell 2; the second guide part includes a second guide rod 5 with a second slider 7, one end of the second guide rod 5 is arranged on the base 1, and the other end is arranged on the first support shell 2; a cylinder is sleeved on the top of the second guide rod 5; preferably, the cylinder is provided with a stop screw hole corresponding to the second guide rod, and the stop nut is screwed on the stop screw hole and abuts against the cylinder to achieve the purpose of fixing and adjusting the position of the cylinder. The base 1 is also provided with a first photoelectric switch 10, such as Figure 3 As shown, in the initial state, the first slider 6 is located at the bottom end of the first guide rod 4, corresponding to the first photoelectric switch 10. When the first slider 6 moves, the first photoelectric switch 10 can sense it and control the first motor electrically connected thereto.

[0031] The first slider is provided with a first rotating wheel, the second slider is provided with a second rotating wheel, and the cylinder can be provided with a plurality of third rotating wheels. The first supporting shell, the first guide rod, and the second guide rod are all provided with a guide wheel 13 or a guide ring.

[0032] The wire-releasing assembly is used to carry the wire reel, and the wire-releasing assembly includes a second supporting shell 8, a second motor, and a rotating shaft 9. Figure 2 As shown. The second support shell 8 is arranged on the base 1, and the second motor is arranged on the second support shell 8. Preferably, the second motor is located in the second support shell 8, so that the second support shell 8 serves the purpose of protecting the second motor. The rotating shaft 9 is arranged on the second support shell 8 through the connecting seat, and the rotating shaft of the second motor is connected to the rotating shaft 9, thereby driving the rotating shaft 9 to rotate; a wire reel with electric wires is sleeved on the rotating shaft 9. A thread is arranged on the rotating shaft 9. After the wire reel is sleeved, the clamping ring is screwed on to ensure that the wire reel does not come out of the rotating shaft. The second photoelectric switch 11 is arranged on the base 1. In the initial state, the second slider 7 is located at the bottom, corresponding to the second photoelectric switch 11, and the second photoelectric switch 11 is electrically connected to the second motor. When the second photoelectric switch 11 detects the movement of the second slider, it controls the second motor to start.

[0033] A vertically arranged displacement sensor 12 is also provided on the first supporting shell 2, and the movable end of the displacement sensor 12 is connected to the second slider 7. The displacement sensor 12 can regulate the second motor by detecting the upward movement distance of the second slider 7. The displacement sensor 12 is electrically connected to the second motor.

[0034] The specific use process is as follows: first, put the matching wire reel on the rotating shaft 9 and fix it with a clamping ring. Then, the wire first passes through the guide ring (guide wheel 13) of the second guide rod 5, bypasses a third rotating wheel of the cylinder, then bypasses the second rotating wheel, then bypasses another third rotating wheel of the cylinder, passes between the two driving wheels 3, bypasses the first rotating wheel, and finally passes through the guide wheel 13 (guide ring) of the first guide rod 4 and enters the electric blanket wiring device;

[0035] When the electric blanket wiring device is wiring, the wire will drive the first slider 6 to rise. When the first photoelectric switch 10 detects it, the first motor controls the two driving wheels 3 to pull the wire a set distance. Driven by this, the second slider 7 rises. After the second photoelectric switch 11 detects it, it controls the second motor to rotate. The rotation speed and frequency of the second motor can be dynamically adjusted according to the distance of the second slider detected by the displacement sensor 12 (this is not the invention of the present utility model and is also the prior art, so it will not be described in detail).

[0036] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
