By controlling the distance between the limit plate and the wire receiving rod, the wire can be wound more neatly and more tightly.

[0004] The disadvantage of the above disclosed solution is that during the wire winding process, the No. 2 cylinder needs to be started again to control the distance between the limit plate and the wire supporting rod, which increases the operation steps, has a low degree of automation, and reduces work efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide an improved inverted wire drawing machine. When the weight of the steel wire is used to drive the bearing plate to move downward, the bearing plate drives the two limit plates to gradually move toward each other, thereby limiting the wound steel wire, which can effectively solve the problems in the background technology.

The two electric telescopic rods pass through the corresponding L-shaped fixing frames and are fixedly connected to the L-shaped fixing frames. The electric telescopic rods pass through the frame and are fixedly provided with a U-shaped frame, and a wire crimping wheel is rotatably provided inside the U-shaped frame.

[0008] Furthermore, a third motor is fixedly arranged on the base, and second rotating shafts are rotatably arranged on both sides of the base, the second rotating shaft passes through the base and rollers are fixedly sleeved at both ends, a guide rail is arranged on the outer periphery of the base, the rollers are placed on the guide rails, and a belt is sleeved on the output shaft of the third motor and the corresponding second rotating shaft.

[0009] Furthermore, a reducer is fixedly arranged on the top of the frame, the input end of the reducer is connected to the output shaft of the first motor, and the output end of the reducer passes through the frame and is fixedly connected to the wire drawing drum.

[0010] Furthermore, a wire drawing powder box is arranged on the frame.

[0011] Furthermore, a control panel is provided on the frame.

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

[0013] Since the fixed plate is rotatably provided with a gear, the gear is meshed with the first rack and the second rack respectively, and a sliding rod is fixedly provided at the bottom of the bearing plate, the bottom of the sliding rod passes through the rotating frame and is slidably connected with the rotating frame, and a spring is sleeved on the sliding rod. Therefore, when the weight of the steel wire on the bearing plate gradually increases, the bearing plate gradually pushes the sliding rod to move downward and gradually compresses the spring, and the bearing plate drives the gear to move downward. Since the gear is meshed with the first rack, the gear rotates when it moves downward, and the rotation of the gear drives the two second racks to move at the same time, and the two second racks drive the two limit plates to gradually move toward each other. When the two limit plates contact the steel wire, the limit plates are blocked by the steel wire and no longer move, so that the bearing plate no longer slides downward. By limiting the wound steel wire by the two limit plates, the steel wire can be wound more neatly and more tightly, and the neatness of the steel wire winding can be improved. Thus, the weight of the steel wire is used to drive the bearing plate to move downward, and the bearing plate moves downward to drive the two limit plates to gradually move toward each other, so that the two limit plates limit the wound steel wire, saving operation steps, high automation, and improving work efficiency.

And the first rack 17 is located between the two second racks 18, so that the first rack 17 does not hinder the vertical or horizontal movement of the two first racks 18.

[0024] A sliding rod 19 is fixedly provided at the bottom of the supporting plate 13, and the bottom of the sliding rod 19 passes through the rotating frame 21 and is slidably connected to the rotating frame 21.

[0027] The working principle of the improved inverted wire drawing machine provided by the utility model is as follows:

[0028] When in use, the electric telescopic rod 7 is started to extend, and the U-shaped frame 6 is pushed to move by the electric telescopic rod 7, and the U-shaped frame 6 drives the wire pressing wheel 5 to approach the wire drawing drum 4, and the gap between the wire pressing wheel 5 and the wire drawing drum 4 is adjusted to be the same as the diameter of the steel wire, so that the steel wire can pass normally. The first motor 2 is started, and the output shaft of the first motor 2 drives the wire drawing drum 4 to rotate through the reducer 3, so that the steel wire passes through the gap between the wire pressing wheel 5 and the wire drawing drum 4 in turn. At the same time, the second motor 23 is started, and the second motor 23 drives the rotating frame 21 to rotate, and the rotating frame 21 drives the bearing plate 13 to rotate, and the bearing plate 13 drives the wire winding frame 11 to rotate, so that after the wire drawing drum 4 and the wire pressing wheel 5 cooperate to draw the steel wire, the steel wire falls on the bearing plate 13, and the steel wire is wound around the wire winding frame 11 from bottom to top.

[0029] When the weight of the steel wire on the bearing plate 13 gradually increases, the bearing plate 13 gradually pushes the sliding rod 19 to move downward and gradually compresses the spring 20. At the same time, the bearing plate 13 drives the gear 16 to move downward. Since the gear 16 is meshed with the first rack 17, the gear 16 rotates when it moves downward. The rotation of the gear 16 drives the two second racks 18 to move at the same time. The two second racks 18 drive the two limiting plates 12 to gradually move toward each other. When the two limiting plates 12 contact the steel wire, the limiting plates 12 are blocked by the steel wire and no longer move, so that the bearing plate 13 no longer slides downward. By limiting the wound steel wire with the two limiting plates 12, the steel wire can be wound more neatly and more tightly, and the neatness of the steel wire winding can be improved.

[0030] After the steel wire is wound, the first motor 2 and the second motor 23 are turned off, and the third motor 24 is turned on. The third motor 24 drives the roller 27 to roll on the guide rail 28 through the belt 25, so that the supporting plate 13 is away from the frame 1, which is convenient for taking out the wound steel wire. After the steel wire is taken out, the restoring force of the spring 20 pushes the supporting plate 13 upward to reset.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
