[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the scope of protection of the present invention. Obviously, the embodiments described in the present invention are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] The wire wheel feed mechanism of the present invention is arranged on one side of the small copper wire drawing machine 1, which is located in the wire drawing feed direction of the small copper wire drawing machine 1. Figure 1 Arrow shown.

[0026] Example 1: The specific structure of the utility model is as follows:

[0027] Please refer to the attached Figure 1 The utility model provides a wire wheel feeding mechanism with an adjustable wire feeding angle, comprising a plurality of wire feeding holes 2 distributed on one side of a small copper wire drawing machine 1, a support plate 5 vertically and horizontally installed on the side, a slider 8, a bracket 4 and a wire wheel 3.

[0028] The plurality of wire inlet holes 2 are distributed linearly and horizontally, such as Figure 1 As shown, the wire feed holes 2 extend linearly through the other side of the small copper wire drawing machine 1, with multiple wire feed holes 2 distributed equidistantly and linearly. Preferably, each wire feed hole 2 is a circular hole, and the metal wire passes around the underside of the wire pulley 3 and into the wire feed hole 2. The diameters of the wire feed holes 2 are not uniform, or some of the wire feed holes 2 are uniform in size.

[0029] The upper surface of the support plate 5 is provided with an inverted "T"-shaped chute 6 that runs through both ends. The inverted "T"-shaped chute 6 is open at the top, and positioning holes 7 are distributed in a linear array along the plate surfaces on both sides of the upper opening of the support plate 5. The positioning holes 7 are connected to the inverted "T"-shaped chute 6; the lower groove body of the inverted "T"-shaped chute 6 has inclined side surfaces on both sides, and the inclined side surfaces form an acute angle with the bottom surface of the inverted "T"-shaped chute 6. The two ends of the slider 8 are inclined to form inclined surfaces 11, and the two inclined surfaces 11 can respectively cooperate with the two inclined sides of the inverted "T"-shaped chute 6. The slider 8 is provided with the inclined surface 11 to facilitate the sliding of the slider 8 and avoid getting stuck in the inverted "T"-shaped chute 6.

[0030] The slider 8 is slidably connected to the inverted "T"-shaped slide groove 6. The upper plate surface of the slider 8 is provided with two insertion holes 10. The moving paths of the two insertion holes 10 pass through the positioning holes 7 distributed in two linear arrays respectively.

[0031] The bracket 4 is fixed on the slider 8 and extends from the upper opening of the support plate 5 to a position close to the wire inlet hole 2. The lower end of the bracket 4 is welded to the slider 8, and the upper end is provided with a U-shaped structural frame.

[0032] The guide pulley 3 is rotatably mounted on the upper end of the bracket 4. Specifically, a bearing is fixed to the inner ring of the guide pulley 3, and the bearing is rotatably mounted to the U-shaped structure by screwing a bolt and nut. The guide pulley 3 rotates as the wire is fed. A circle of inner grooves is formed along the circumference of the guide pulley 3.

[0033] The wire wheel feeding mechanism also includes a positioning rod 9, which can be inserted into the positioning hole 7 and the insertion hole 10 and can keep a part of the rod body in the insertion hole 10 and a part of the rod body in the positioning hole 7. The positioning rod 9 positions the decorative slider 8, thereby positioning the wire wheel 3.

[0034] As described above, the guide wheel 3 , the bracket 4 and the slider 8 form an integral structure that can be taken out of and put into the inverted “T”-shaped slide groove 6 .

[0035] Example 2:

[0036] The following is the processing process of the wire pulley feeding mechanism of the utility model:

[0037] Step 1: prepare a steel plate, dig a groove on one side of the steel plate to form the inverted "T"-shaped slide groove 6, and set the two sides of the lower groove body of the inverted "T"-shaped slide groove 6 into side slopes, which form an acute angle with the bottom surface of the inverted "T"-shaped slide groove 6.

[0038] Step 2: Punch holes at equal intervals on the plate surface on both sides of the upper opening of the steel plate to form the positioning holes 7. The processed steel plate is vertically welded to the side of the small copper wire drawing machine 1 and is located a distance below the wire feed hole 2.

[0039] Step three, make the slider 8, which matches the inverted "T"-shaped slide groove 6. It can move easily along the inverted "T"-shaped slide groove 6 and the socket 10 on the slider 8 can pass through the positioning hole 7 when moving. The sizes of the socket 10 and the positioning hole 7 match.

[0040] Step 4: Make a guide wheel bracket assembly, which includes: a bracket 4 and a wire wheel 3 vertically welded to the upper surface of the slider 8. The upper end of the bracket 4 is a U-shaped structure frame. The inner ring of the wire wheel 3 is fixed with a bearing, and the bearing is rotatably installed on the U-shaped structure frame by screws and bolts. Above, the bracket 4, wire wheel 3 and slider 8 form a whole.

[0041] Step 5. When the smallest incoming wire size is selected, move the slider 8 to the position of the positioning hole 7 corresponding to the smallest incoming wire hole 2, insert the lower part of the positioning rod 9 into the positioning hole 7 and enter the socket 10. The positioning rod 9 limits the slider 8 and the slider 8 cannot move.

[0042] Step 6: The copper wire passes through the wire pulley 3 and enters the wire entry hole 2, the wire drawing equipment is started, and the wire drawing action begins.

[0043] In summary, by improving the slider 8, the support plate 5, and the inverted "T"-shaped chute 6, the wire pulley feeding mechanism can be realized, regardless of the size and position of the wire feeder, by moving the slider 8 in the inverted "T"-shaped chute 6, stopping at the appropriate wire feeder hole 2 position, and then inserting the positioning rod 9 into the positioning hole 7 and the jack 10 to achieve positioning. The utility model selects different wire feeder holes 2 according to the single wires of different sizes to be drawn, and only one wire pulley is needed to achieve this, without the need for multiple wire pulleys to adjust the angle. First, it reduces the frequency of wire pulley purchases and saves costs. In the past, each wire feeder hole had to be equipped with a corresponding wire pulley. Now, a wire pulley can be moved to switch between wire feeder holes 2 of different apertures. Second, it reduces maintenance costs. In the past, if one of the multiple wire pulley groups broke, all of them had to be disassembled for maintenance, which was costly and time-consuming, reducing production efficiency. Now, a single wire pulley can be easily replaced, which can quickly meet production requirements. Third, the entire structure of the wire pulley feeding mechanism is simple, applicable, beautiful and neat, and highly reliable.

[0044] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
