Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of wire processing, and particularly relates to a feeding device for a wire cutting machine. BACKGROUND

[0002] The wire is a wire for conducting current, and the wire needs to be conveyed during the wire processing process, so that the wire can be wound on a reel. The existing wire feeding device has a relatively complex structure and low wire feeding efficiency. Moreover, the size of the wire feeding channel of the existing wire feeding device cannot be adjusted, so it can usually only convey one specification and size of wire, and has a single function, which cannot meet the production requirements. Patent No. CN218968456U, a wire feeding device for wire processing, uses manual rotation of the support screw to control the gap size between the auxiliary wheel and the wire feeding wheel, so that wires of different sizes can pass through and be fed. However, manual operation is prone to errors, and the wire feeding seat cannot always be kept in a horizontal position when the support screw is rotating, so the gap size between the auxiliary wheel and the wire feeding wheel is inconsistent, which may cause the wire to be fed unevenly, affecting the wire feeding effect. SUMMARY

[0003] In view of the above defects or shortcomings in the prior art, it is desirable to provide a feeding device for a wire cutting machine.

[0004] According to the technical scheme provided by the embodiments of the present application, a feeding device for a wire cutting machine includes a box body and a wire feeding plate fixedly installed on the end face of the box body. A plurality of driving wire feeding wheels arranged in a straight line and rotating relative to the wire feeding plate through a transmission motor are fixedly arranged on the wire feeding plate. A lifting type driven wire feeding wheel is arranged above each of the plurality of driving wire feeding wheels. A rotating cam rod is arranged below the wheel shaft of the lifting type driven wire feeding wheel. The rotating cam rod is rotated by a rotating motor fixed in the box body. When the rotating cam rod rotates, it can drive the plurality of lifting type driven wire feeding wheels to move up and down on the wire feeding plate, so as to adjust the distance between the lifting type driven wire feeding wheel and the driving wire feeding wheel.

[0005] Further, the rotating cam rod includes a shaft and a rod-shaped cam fixedly sleeved on the shaft. The rotating motor is fixedly connected to the shaft. The lifting of the lifting type driven wire feeding wheel is realized by the arc-shaped protrusions on the rod-shaped cam.

[0006] Further, a vertical sliding hole is arranged on the wire feeding plate. The wheel shaft of the lifting type driven wire feeding wheel is slidingly connected to the inner end face of the sliding hole through a protruding block. One end of the wheel shaft of the lifting type driven wire feeding wheel is slidingly connected to a partition plate in the box body after passing through the sliding hole, so as to realize the stable lifting of the lifting type driven wire feeding wheel.

[0007] Further, the plurality of rotating cam rods are arranged in a straight line, and the rod-shaped cams on the plurality of rotating cam rods abut different parts of the wheel shaft of the lifting secondary conveying line wheel, so as to balance the lifting of the wheel shaft of the lifting secondary conveying line wheel.

[0008] Further, the plurality of driving conveying line wheels are connected through the belt pulley, so as to realize synchronous and same direction rotation of the plurality of driving conveying line wheels.

[0009] Further, the driving conveying line wheel and the lifting secondary conveying line wheel are both provided with anti-skid protrusions, so as to increase the friction between the conveyed electric wire and the conveying line wheel, and facilitate the conveying.

[0010] In summary, the beneficial effects of the present application are as follows: the device of the present application utilizes the abutment of the rod-shaped cam and the lifting secondary conveying line wheel, and when the rod-shaped cam rotates, it can simultaneously drive the rotation of the plurality of lifting secondary conveying line wheels, ensure the synchronous lifting of the plurality of lifting secondary conveying line wheels, make the gap between the driving conveying line wheel and the lifting secondary conveying line wheel consistent, and ensure the conveying effect of electric wires of different sizes; meanwhile, the abutment of the plurality of rod-shaped cams and the wheel shaft of the lifting secondary conveying line wheel prevents the imbalance of the lifting secondary conveying line wheel caused by point transmission when the lifting secondary conveying line wheel is lifted, and affects the lifting secondary conveying line wheel.

Figure 1

[0019] As shown in the figure, the rear end part of the wheel shaft of the lifting type driven thread feeding wheel 4 is slidingly connected with the partition plate arranged in the box body 1 through the vertically arranged sliding hole 21 of the thread feeding plate 2, and the wheel shaft of the lifting type driven thread feeding wheel 4 is slidingly connected with the side end face of the sliding hole 21, and the connection mode is that a sliding block is fixedly arranged on the wheel shaft of the lifting type driven thread feeding wheel 4, and the sliding block slides in the sliding groove of the side end face of the sliding hole 21; similarly, the rear end part of the wheel shaft of the lifting type driven thread feeding wheel 4 is slidingly connected with the partition plate in the box body 1 in the same way as above. Figure 1 Figure 2

[0020] As shown in the figure, the rotating cam rods 5 are arranged in the inner cavity of the box body 1 and the thread feeding plate 2 below the wheel shaft of the lifting type driven thread feeding wheel 4, two rotating cam rods 5 arranged in a longitudinal horizontal straight line abut against two point parts of the rear end part of the wheel shaft of the lifting type driven thread feeding wheel 4, and the two rotating cam rods 5 are fixedly connected with the rotating motor 6 through gears, and the rotating motor 6 is fixedly arranged in the box body 1, so that the two rotating cam rods 5 are synchronously rotated by the starting of the rotating motor 6.

[0022] ​​​​Before use, the distance between the lifting secondary wire feeding wheel 4 and the primary wire feeding wheel 3 directly below it is adjusted according to the diameter of the wire to be fed, the rotary motor 6 is started, the rotating cam rod 5 is rotated, and because the rod-shaped cam 52 on the rotating cam rod 5 is in abutment with the wheel shaft of the lifting secondary wire feeding wheel 4, when the rod-shaped cam 52 rotates, the protrusions on the rod-shaped cam 52 are in abutment with the wheel shaft of the lifting secondary wire feeding wheel 4, the wheel shaft of the lifting secondary wire feeding wheel 4 can be lifted to the position farthest from the primary wire feeding wheel 3, and the arc-shaped protrusions on the rod-shaped cam 52 can adjust the distance between the wheel shaft of the lifting secondary wire feeding wheel 4 and the center line of the rotating cam rod 5 when the rotating cam rod 5 rotates, thereby achieving the lifting of the lifting secondary wire feeding wheel 4.
