The shaft is firmly fixed on the bracket, and the entire device is fixed to the ground or equipment through the bracket. When replacing or cleaning the wire pulley, the entire device needs to be disassembled. This integral structure is quite troublesome and laborious to disassemble and assemble. Among them, the wire surface of the wire pulley adopts a full circumferential surface structure, the contact surface between the wire and the wire pulley is large, the friction force is large, and the wear on the wire increases accordingly. Especially for some brittle material yarns, the wire is easy to get hairy and affect the yarn quality. For wet-wound dipped yarn, the full circumferential surface structure makes it easy for the wire to stick to the wire pulley. Summary of the invention

[0006] The object of the present invention is to provide an easily detachable low-friction conductor wire device to solve the problems of the existing conductor wire devices being inconvenient to use and disassemble and being easy to cause wear to the wire.

[0007] In order to solve the above problems, the present invention discloses an easily detachable low-friction wire device, comprising a bracket and a wire wheel assembly, wherein the wire wheel assembly is mounted on the bracket, the wire wheel assembly comprises a wire wheel, a mounting shaft and a bearing, the wire wheel is mounted on the mounting shaft through the bearing, the mounting shaft is fixed to the bracket, a mounting notch is provided on the bracket, the mounting shaft is arranged in the mounting notch, the mounting shaft is fixed in the mounting notch by a set screw, and a plurality of arc-shaped protrusions are evenly distributed on the wire wheel.

[0008] As a further improvement of the above technical solution:

[0009] The installation shaft is a stepped shaft that is larger in the middle and smaller at both ends, a shaft shoulder is provided in the middle portion, one side of the bearing is close to the shaft shoulder, and a retaining ring is provided on the other side.

[0010] The guide wheel is provided with a mounting groove, the upper part of the bearing is installed in the mounting groove, and a right dust cover is provided on the right side of the guide wheel, and one end of the right dust cover is in contact with the bearing.

[0011] A left dust cover is arranged on the left side of the guide wheel.

[0012] A felt ring is arranged between the left dust cover, the right dust cover and the mounting shaft.

[0013] The bracket is provided with connecting bolts.

[0014] The present invention also discloses a method for using an easily detachable low-friction conductor device, comprising the following steps:

[0015] S1. Assembly of the guide wheel assembly: insert the bearing from the right end of the mounting shaft until the left end of the bearing inner ring is close to the shoulder of the mounting shaft and tightly fits in the middle section of the mounting shaft. The right end of the bearing inner ring is blocked by a retaining ring to prevent axial movement. Insert the guide wheel from the left end of the bearing until the end face of the step inner hole is close to the left end of the bearing outer ring and is tightly fitted on the bearing. The right end of the bearing outer ring is tightened with the right dust cover; put the left dust cover and the right dust cover on the symmetrical ends of the mounting shaft, adjust the installation position, and fix them on the guide wheel with connecting screws; before installing the dust cover, install felt rings in the trapezoidal grooves of the left dust cover and the right dust cover, so that the left dust cover and the right dust cover are sealed and connected to the mounting shaft.

[0016] S2. Insert the installed wire wheel assembly into the installation notches of the two vertical plates of the bracket, and fine-tune its position in the inverted U-shaped arch groove of the bracket to the left and right to make the gaps between the left and right dust covers and the vertical plates uniform, and then tighten the left and right set screws to tighten the installation shaft into the installation notch.

[0017] S3. Insert the wire from one side of the bracket and pull it out from the other side. Under the action of the wire tension T, the wire wheel rotates counterclockwise. It is always subject to downward and tangential forces, so that the installation shaft is always in a downward sliding trend in the installation notch and will not leave the installation notch due to loosening of the set screw;

The easily detachable structural design makes assembly and disassembly convenient and quick, saves time and effort, can greatly reduce the labor intensity of workers, and improve work efficiency; the conductor wheel has a circular arc gear-type appearance structure with a novel design. When passing the wire, the wire only contacts the top circular arc surface. Compared with the whole cylindrical surface structure, the contact area between the wire and the conductor wheel can be greatly reduced, the friction wear on the wire can be reduced, and the winding quality of the product is greatly improved. The same side of the two vertical plates of the bracket cleverly adopts a notch inclined upward design, so that the installation shaft is always in a sliding and falling trend in the inclined groove under the action of the combined force, which greatly improves the safety of use. The axial concave arc section design of the conductor wheel limits the movement of the wire and makes it difficult to run out from the bottom of the concave arc. The problems of inconvenient use, inconvenient disassembly, and easy wear on the wire of the existing conductor device are solved. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 5 As shown, the easily removable low-friction wire guide device of this embodiment includes a bracket 1 and a wire guide wheel assembly. The wire guide wheel assembly is installed on the bracket 1. The wire guide wheel assembly includes a wire guide wheel 2, a mounting shaft 6 and a bearing 8. The wire guide wheel 2 is installed on the mounting shaft 6 through the bearing 8. The mounting shaft 6 is fixed on the bracket 1. The bracket 1 is an arched part with a convex edge around the upper mounting surface. The upper mounting surface is a steel plate. There are 4 bolt mounting holes symmetrically distributed around the convex edge. A connecting bolt 12 is arranged on the bolt mounting hole. The two vertical plates are rectangular. The two vertical plates have an inclined groove with an upward opening on the same side. There is a small horizontal straight line segment above and below the shaft mounting position at the bottom of the inclined groove, and the closed side is a semicircular arc tangent to the straight line segment, which is defined as a mounting notch 11. After the mounting shaft 6 is installed, it contacts the slot hole on three sides. There is a threaded hole perpendicular to the straight line segment at the shaft mounting position at the bottom of the inclined groove, and a set screw 7 is installed therein. The axis of the screw hole is colinear with the diameter of the semicircular arc, so that the shaft is tightened more securely. The installation shaft 6 is a stepped shaft, and the shoulder of the largest shaft diameter acts as a limiter when the bearing 8 is installed. The larger shaft section on the right side of the shoulder is the installation location of the bearing 8, and the outer edge processing size accuracy and surface roughness requirements are high. There is a tool withdrawal groove on the installation shaft 6, which is the installation location of the retaining ring 9. The larger shaft sections on both sides are the installation locations of the left and right dust covers. The small shaft at the end is the shaft section installed with the bracket 1, and is also the tightening location of the set screw 7.

[0032] There are several arc-shaped protrusions 21 evenly distributed on the wire wheel 2, which can be considered as a gear-type appearance structure. The contact area between the wire and the wire wheel 2 is reduced, the wear of the wire wheel 2 on the wire is reduced, and the winding quality and product qualification rate of the product are improved. For wet winding of dipped yarn, the top of the arc-shaped protrusion structure can also play the role of scraping glue. The axial section of the wire wheel 2 is a concave arc, so that the wire is not easy to run out from the bottom of the concave arc. A mounting groove is provided in the wire wheel 2, and the upper part of the bearing 8 is installed in the mounting groove. A right dust cover 5 is provided on the right side of the wire wheel 2, and one end of the right dust cover 5 abuts against the bearing 8. A left dust cover 4 is provided on the left side of the wire wheel 2. A felt ring 10 is provided between the left dust cover 4 and the right dust cover 5 and the mounting shaft 6. A connecting bolt 12 is provided on the bracket 1. The whole is fixed in the mounting position by the connecting bolt 12. Three threaded holes are evenly processed on the end faces of both sides of the wire wheel 2 for the installation of the left and right dust covers. Its inner hole is a stepped hole, and the bearing 8 is installed from the right end of the larger inner hole, and the left end face of the outer ring is closely positioned against the step surface of the inner hole.

[0033] The installation shaft 6 is a stepped shaft with a large middle and small ends. A shaft shoulder is provided in the middle part. One side of the bearing 8 is close to the shaft shoulder, and a retaining ring 9 is provided on the other side. During assembly, the bearing 8 is inserted from right to left and tightly fitted in the middle section of the installation shaft 6. The left end face of the inner ring of the bearing 8 is close to the shaft shoulder of the shaft, and the right end face of the inner ring of the bearing 8 is blocked by the retaining ring 9 to prevent axial movement. The guide wheel 2 is inserted from left to right until the step end face of the inner hole is close to the left end of the outer ring of the bearing 8 and is tightly fitted on the outer ring of the bearing 8. The right end face of the outer ring of the bearing 8 is supported by the annular shaft end of the right dust cover 5 at the same time. Then the left and right dust covers are fixed to the two ends of the guide wheel 2 with three connecting screws 3 respectively. Two flexible felt rings 10 are squeezed into the trapezoidal grooves of the left dust cover 4 and the right dust cover 5 respectively, wrapping the outer edge of the installation shaft 6, effectively preventing dust, liquid, etc. from entering the bearing. The assembled and debugged wire wheel assembly is installed into the inverted U-shaped arch groove between the two vertical plates of the bracket 1. At the same time, the small shafts at both ends of the installation shaft 6 are installed into the inclined grooves of the vertical plates and slide into the bottom. Then, the installation shaft 6 is tightened with two set screws 7 to fix the installation shaft 6 and the bracket 1 as a whole.

[0034] The left dust cover 4 is a stepped circular cover-shaped part. There are three countersunk screw holes evenly distributed on the circular end surface of the cover-shaped large shaft. The screws 3 pass through the holes to fix it on the wire wheel 2. The chamfered end surface of the outer edge of the small ring shaft is convenient for installation into the wire wheel hole. The outer edge of the ring shaft cooperates with the inner hole of the wire wheel 2 to play a guiding role. The diameter of the small ring shaft of the right dust cover 5 is slightly larger than that of the left dust cover 4. The end surface of the small ring presses against the outer ring of the right end of the bearing 8 to play a positioning role. There is a large circular hole and a trapezoidal slot hole for installing a felt ring 10 in the middle. The felt ring 10 can prevent dust and liquid from entering the bearing.

[0035] This embodiment also discloses a method for using an easily detachable low-friction wire device, comprising the following steps:

[0036] S1. Assembling the guide wheel assembly: insert the bearing 8 from the right end of the mounting shaft 6 until the left end of the inner ring of the bearing 8 is close to the shoulder of the mounting shaft 6 and is tightly sleeved in the middle section of the mounting shaft 6. The right end of the inner ring of the bearing 8 is blocked by a retaining ring 9 to prevent axial movement. The guide wheel 2 is inserted from the left end of the bearing 8 until the end face of the inner hole of the step is close to the center of the left end of the outer ring of the bearing 8 and is tightly sleeved on the bearing 8. The right end of the outer ring of the bearing 8 is tightened by the right dust cover 5; install the felt ring 10 in the trapezoidal grooves of the left dust cover 4 and the right dust cover 5, so that the left dust cover 4 and the right dust cover 5 are sealed and connected with the mounting shaft 6, effectively preventing dust, liquid, etc. from entering the bearing 8; sleeve the left dust cover 4 and the right dust cover 5 on the symmetrical ends of the mounting shaft 6, adjust the installation position, and fix them on the guide wheel 2 with the connecting screws 3; in the assembled guide wheel assembly, the inner ring of the bearing 8 has no relative movement with the mounting shaft 6, and the outer ring of the bearing 8 is connected with the guide wheel 2 and the dust cover as a whole. Gently move the outer edge of the wire wheel, and the wire wheel can rotate freely around the installation axis 6.
