[0022] Specifically, the cross-section of the wax block 8 is set to be diamond-shaped, and a groove 801 matching the retaining spring 9 is opened on the side wall of the wax block 8; a mounting portion 701 is set on the top of the wax shaft 7, and the mounting portion 701 is cut off a portion on each side of the cylindrical wax shaft 7 so that a plane appears in the vertical direction, and the retaining spring 9 is clamped in the groove 801 on the outside of the wax block 8, and will not touch the retaining spring 9 when the yarn contacts the wax block 8. The clamping parts at both ends of the retaining spring 9 pass through the wax block 8 and are clamped on both sides of the mounting portion 701, thereby fixing the wax block 8 to the wax shaft 7; the retaining spring is used to fix the wax block, which is convenient for disassembly and replacement of the wax block.

[0023] When in use, the first motor 3 is started, and the first motor 3 drives the second gear 6 to rotate. The rotation of the second gear 6 drives the two first gears 4 to rotate, thereby driving the two wax shafts 7 and the wax block 8 to rotate. The linear speed of the wax block 8 at the contact point with the yarn is set to be opposite to the speed direction of the yarn to ensure relative movement between the two so that the yarn can be effectively waxed.

[0024] like Figure 4As shown, the reciprocating lifting mechanism includes a mounting plate 10, the upper and lower ends of the mounting plate 10 are connected to the inner wall of the driving box 1, a slide groove 1001 is opened on the upper part of the mounting plate 10, a slider 11 is slidably connected in the slide groove 1001, the top surface of the slider 11 is connected to the push rod 17, the front of the slider 11 is connected to a cross bar 12, the two ends of the cross bar 12 are movably connected to a connecting rod 16, the front of the mounting plate 10 and near the bottom are rotatably connected to a third gear 13 and a fourth gear 14, the third gear 13 and the fourth gear 14 are meshed, the front of the third gear 13 and the fourth gear 14 are both connected to a connecting column 15, and the bottom end of the connecting rod 16 is movably connected to the connecting column 15; specifically, the cross section of the slider 11 is set to an I-shape to prevent the slider 11 from detaching from the slide groove 1001.

[0025] When in use, the third gear 13 and the fourth gear 14 rotate in opposite directions. When the fourth gear 14 rotates clockwise, the third gear 13 rotates counterclockwise, and the two connecting posts 15 rotate synchronously with the third gear 13 and the fourth gear 14 respectively. Figure 4 Starting from the position shown, when the two connecting columns 15 rotate upward, the two connecting rods 16 push the cross bar 12 upward, thereby driving the slider 11 to slide upward along the slide groove 1001, and the push rod 17 pushes the lifting box 2 upward, and the lifting box 2 rises; after the two connecting columns 15 rotate upward to the highest point, they begin to rotate downward, and the two connecting rods 16 pull the cross bar 12 downward, thereby driving the slider 11 to slide downward along the slide groove 1001, and the push rod 17 pulls the lifting box 2 downward, and the lifting box 2 descends; the lifting box 2 is driven to reciprocate up and down by the third gear 13 and the fourth gear 14; during the reciprocating lifting process of the lifting box 2, the wax block is driven to reciprocate and lift, so that the surface of the wax block 8 can contact the yarn, thereby improving the uniformity of the wear of the wax block 8 and avoiding the waste of the wax block 8 caused by uneven wear of the wax block 8. At the same time, the wax block 8 that moves up and down can move up and down to wax the surface of the yarn, thereby improving the uniformity of the wax on the yarn and ensuring the lubricity of the surface of the yarn.

[0026] like Figure 5 , 6 As shown, the driving assembly includes a second motor 18, which is mounted behind the mounting plate 10 on the right side, and the output shaft of the second motor 18 is connected to the central shaft of the fourth gear 14 on the right side, and a driving wheel 19 is also mounted on the output shaft of the second motor 18, and a driven wheel 20 is mounted on the central shaft of the fourth gear 14 on the left side, and the driving wheel 19 and the driven wheel 20 are connected by a synchronous belt 21. When in use, the second motor 18 is started, and the second motor 18 drives the driving wheel 19 to rotate, and the driving wheel 19 drives the driven wheel 20 to rotate through the synchronous belt 21, thereby driving the two reciprocating lifting mechanisms to move synchronously, so that the two push rods 17 push the lifting box 2 to rise and fall.

[0027] The working process of the utility model is as follows:

[0028] First, the yarn is wound in an S shape on two wax blocks 8, and then the first motor 3 is started to drive the two wax blocks 8 to rotate. The linear speed of the wax block 8 at the contact point with the yarn is opposite to the speed direction of the yarn to ensure relative movement between the two so that the yarn is effectively waxed; in this process, the second motor 18 is started, and the second motor drives the two reciprocating lifting mechanisms to move synchronously, so that the two push rods 17 push the lifting box 2 to move up and down, thereby driving the wax block 8 to move up and down, so that the surface of the wax block 8 can contact the yarn, thereby improving the uniformity of the wear of the wax block 8. At the same time, the wax block 8 that moves up and down can move up and down to wax the surface of the yarn, thereby improving the uniformity of the waxing on the yarn and ensuring the lubricity of the yarn surface.
