DETAILED DESCRIPTION

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 to 5 shown, a copper wire drawing device for silver-plated wire production includes a housing 2 and a base 1 connected in sequence from top to bottom; a plurality of drawing rollers 3 are movably installed on the front surface of the housing 2, and a drawing die 4 is provided between every two mutually cooperating drawing rollers 3;

[0022] The base 1 is provided with an inner cavity, and an opening leading to the inner cavity is provided on the upper end surface of the base 1;

[0023] A filter plate 7 is provided in the middle of the inner cavity, and a plurality of filter holes are provided on the filter plate 7; a left rotating shaft 6 is provided at the left end of the filter plate 7 and is hinged to the inner cavity through the left rotating shaft 6; inclined plates 5 inclined towards the filter plate 7 are fixedly installed on both the left and right sides of the inner cavity;

[0024] A right rotating shaft 9 is also rotatably connected in the inner cavity. The right rotating shaft 9 is provided below the right end of the filter plate 7, and an elliptical block 10 is sleeved on the outer periphery of the right rotating shaft 9. The elliptical block 10 abuts against the bottom of the filter plate 7, causing the filter plate 7 to incline from left to right;

[0025] A power motor 8 is fixedly installed on the front side wall of the base 1. The output shaft of the power motor 8 penetrates the front side wall of the base 1 and extends into the inner cavity to be connected to the right rotating shaft 9;

[0026] A left drawer 11 and a right drawer 13 adjacent to each other are embedded in the front side wall of the base 1, and the left drawer 11 and the right drawer 13 extend into the inner cavity; and the left drawer 11 is provided directly below the filter plate 7.

[0027] When drawing copper wire, the copper powder generated will slide along the upper surface of the inclined plate 5 together with the coolant onto the upper surface of the filter plate 7. The coolant will fall into the interior of the left drawer 11 through the filter plate 7. The operator starts the power motor 8, causing the right rotating shaft 9 to drive the elliptical block 10 to rotate. Thus, the elliptical block 10 can squeeze and push the filter plate 7 to rotate around the left rotating shaft 6. As the elliptical block 10 continuously rotates, the filter plate 7 will rotate, enabling the copper powder on the upper surface of the filter plate 7 to slide along the upper surface of the filter plate 7 into the interior of the right drawer 13.

[0028] Further, a fixing block 14 is fixedly installed in the inner cavity. The fixing block 14 is located below the filter plate 7. The upper end surface of the fixing block 14 is fixedly connected to a first spring 15, and the upper end of the first spring 15 is fixedly connected to the lower surface of the filter plate 7. When the elliptical block 10 rotates and drives the filter plate 7 to rotate relative to the left rotating shaft 6, the first spring 15 will be stretched to generate elastic deformation, generating an elastic force for restoring deformation and driving the filter plate 7 to reset.

[0029] A baffle 16 extending in the left-right direction is fixedly connected to the upper side of the base 1, and the left and right ends of the baffle 16 are fixedly connected to the inner wall of the housing 2. By providing the baffle 16, the baffle 16 can play a role in blocking to prevent the coolant from splashing to the outside.

[0030] An impurity removal mechanism is fixedly installed on the left side wall of the housing 2. The impurity removal mechanism includes:

[0031] Two side plates 17 are arranged on the left side wall of the housing 2 at a left-right interval. Vertical hollow parts are provided in the middle of the side plates 17 and are connected to vertically arranged connecting rods 18.

[0032] Two sliders 19 are respectively slidably connected to the middle parts of the corresponding connecting rods 18. The opposite surfaces of the two sliders 19 are fixedly connected to cleaning blocks 20 for removing copper wire impurities. The two cleaning blocks 20 are in contact with each other, and through holes for the copper wire to pass through are provided in the middle parts of the mutually contacting cleaning blocks.

[0033] Two moving plates 22 are respectively arranged above and below the two sliders 19, and the moving plates 22 are both slidably connected to the connecting rods 18.

[0034] Two second springs 21 are respectively fixedly connected between the corresponding moving plates 22 and sliders 19; and

[0035] A driving mechanism is connected to the two moving plates 22 and drives the two moving plates 22 to move up and down.

[0036] The driving mechanism is a driving motor 24 arranged on the left side wall of the housing 2;

[0037] A rotating shaft 25 is fixedly connected to the output shaft of the driving motor 24, and the rotating shaft 25 is rotatably connected to the left side wall of the housing 2;

[0038] Moreover, a rotating rod 26 is fixedly sleeved on the outer surface of the rotating shaft 25, and hinge rods 27 are hinged to both the upper and lower ends of the rotating rod 26; the other ends of the two hinge rods 27 are respectively hinged to the corresponding connecting plates 23. It should be noted that the two side plates 17 have the same size; when the driving motor 24 operates, the rotating shaft 25 can drive the rotating rod 26 to rotate, thereby enabling the hinge rods 27 to pull the two connecting plates 23 to move towards each other, so as to drive the cleaning block 20 to perform reciprocating up and down movement to scrape the impurities on the copper wire.

[0039] Furthermore, a vertically arranged partition plate 12 is fixedly connected to the lower side of the inner cavity, and the partition plate 12 is arranged between the left drawer 11 and the right drawer 13. The arrangement of the partition plate 12 can prevent the left drawer 11 and the right drawer 13 from colliding during access.

[0040] The working principle and usage process of the present utility model:

[0041] After an operator passes the copper wire to be drawn through the gaps between the wire drawing rollers 3, the wire drawing die 4, and the two cleaning blocks 20, it passes out through the right side of the housing 2, and then the wire drawing process is carried out on the copper wire through the starting device; when the copper wire passes between the two cleaning blocks 20, the driving motor 24 causes the rotating shaft 25 to drive the rotating rod 26 to rotate, enabling the hinge rods 27 to drive the two connecting plates 23 to move towards each other, and then the connecting plates 23 drive the two moving plates 22 to move towards each other; then, the acting force generated by the second spring 21 is used to push the two cleaning blocks 20 to rub on the outer surface of the copper wire to clean the impurities on the outer surface of the copper wire, avoiding the impurities on the outer surface of the copper wire from affecting the quality of copper wire drawing;

[0042] At the same time, the power motor 8 drives the right rotating shaft 9 to rotate, thereby driving the elliptical block 10 to rotate, enabling the elliptical block 10 to continuously squeeze and push the filter plate 7 to rotate by a certain angle relative to the left rotating shaft 6. The rotation of the filter plate 7 will stretch the first spring 15, and the deformation of the first spring 15 generates a restoring force to pull the filter plate 7 back to its original position. This process of rotation and reset will be continuously repeated as the elliptical block 10 rotates, causing the filter plate 7 to shake up and down, and finally making the filter plate 7 produce an effect similar to vibration;

[0043] The coolant and the copper powder generated during the wire drawing process will fall on the upper surface of the inclined plate 5 and slide down along the upper surface of the inclined plate 5 to the upper surface of the filter plate 7. The 'vibrating' filter plate 7 allows the coolant to fall into the left drawer 11 through the filter holes, and the copper powder will gradually slide down along the upper surface of the filter plate 7 into the interior of the right drawer 13. The entire process realizes the automatic separation of the copper powder and the coolant, enabling both the copper powder and the coolant to be recycled.

[0044] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
