Description

Technical Field

[0001] The utility model relates to the technical field of wire-laying equipment, in particular to a wire-laying device of an enameling machine. Background Art

[0002] The pay-off device of the enameled wire is a key component of the enameling machine. Its function is to pay out the raw wire from the spool and finally make the insulated enameled wire through a series of processes such as annealing and painting. The pay-off device of the enameling machine plays a vital role in the production process. It not only affects the production efficiency, but also is directly related to the quality of the product.

[0003] However, in the current pay-off devices of most enameling machines, an I-shaped pay-off wheel is usually directly mounted on the ground or on the optical axis at the lower end of the frame, and the bottom surface of the pay-off wheel is directly in contact with the ground or the frame, and the raw material line is pulled to be output. However, due to the poor fixing effect of the pay-off wheel, during the pulling process of the raw material line, the pay-off wheel jumps on the optical axis, and even the pay-off wheel rotates unsmoothly. After the raw material line is pulled out, it is easy to scrape on the edge of the pay-off wheel, which causes the pay-off wheel to get stuck, and the raw material line is scratched or broken, which interrupts production and reduces production efficiency. Utility Model Content

[0004] In order to overcome the defects of the prior art, the utility model provides a wire pay-off device for an enameling machine, aiming to solve the above-mentioned problems.

[0005] The utility model adopts the following technical solution to solve the technical problem: a wire-paying device of an enameling machine, comprising a wire-paying frame, a plurality of wire-paying units being installed at the lower end of the wire-paying frame, the plurality of wire-paying units each comprising a fixed shaft fixedly installed at the lower end of the wire-paying frame, a conical table being installed at the lower outer wall of the fixed shaft via a bearing, a limiting assembly being detachably installed at the upper part of the fixed shaft, a wire-paying wheel being clamped between the conical table and the limiting assembly, a guide assembly rotatable around the fixed shaft being provided at the upper end of the limiting assembly, the diameter of the rotating surface of the guide assembly being larger than the diameter of the wire-paying wheel.

[0006] The beneficial effect of the utility model is that the pay-off wheel is prevented from jumping by clamping it between the conical table and the limit assembly. When the raw material line is pulled out, the pay-off wheel can be pulled to rotate, thereby driving the conical table to rotate synchronously around the fixed axis 4, thereby improving the rotation smoothness of the pay-off wheel and preventing the wheel from getting stuck and causing the line to break. At the same time, the guide assembly can guide the raw material line to the outside of the pay-off wheel for traction, preventing the raw material line from contacting the edge of the pay-off wheel and causing scratches, thereby reducing the phenomenon of production interruptions and reducing production efficiency.

[0007] Furthermore, the limiting assembly includes a limiting plate, a threaded section is provided on the upper outer wall of the fixed shaft, the limiting plate is threadedly connected to the threaded section, and a plurality of circumferentially distributed rollers are installed on the lower end surface of the limiting plate, and the rollers abut against the upper surface of the pay-off wheel.

[0008] After adopting the above-mentioned further structure, the limit plate can be easily removed from the fixed shaft to facilitate replacement of the pay-off wheel. Moreover, after the pay-off wheel is clamped between the conical table and the limit plate, the pay-off wheel and the limit plate are connected by rollers to prevent the limit plate from jamming the pay-off wheel.

[0009] Furthermore, the guide assembly includes a curved arm located at the upper end of the limiting plate, one end of the curved arm is sleeved on the threaded segment, and the other end is equipped with a guide ring. The curved arm and the limiting plate are slidingly arranged and the curved arm can rotate around a fixed axis. A pressure cover is provided at the upper end of the curved arm, and the pressure cover is threadedly connected to the threaded segment.

[0010] After adopting the above-mentioned further structure, one end of the curved arm close to the guide ring extends to the outside of the pay-off wheel, so that the raw material line passes through the guide ring. During the traction and output process of the raw material line, since the guide ring can be rotated to adjust the position, the height position of the raw material line can be adaptively adjusted, so that the raw material line will not contact the pay-off wheel and be scratched.

[0011] Furthermore, the upper end surface of the limiting plate is provided with balls distributed in a circumference, and the lower end surface of the crank arm is in contact with the balls.

[0012] After adopting the above further structure, the crank arm can rotate under the action of the ball, preventing the crank arm from being stuck.

[0013] Furthermore, a limiting ring is disposed on the lower end surface of the pressure cover, and a limiting groove corresponding to the limiting ring is disposed on the upper end surface of the curved arm, and the height of the limiting ring is greater than the depth of the limiting groove.

[0014] After adopting the above-mentioned further structure, the position of the crank arm can be limited by the pressure cover. Specifically, after the pressure cover is tightened on the fixed shaft, the limit ring abuts against the bottom wall of the limit groove. At this time, there is a gap between the remaining lower end surface of the pressure cover and the crank arm. During the upward traction of the raw material line, the limit ring is used to prevent the crank arm from jumping up and down too much, and the contact area between the limit ring and the limit groove is relatively smaller, thereby reducing the friction force generated by the crank arm and the pressure cover when the crank arm rotates. Moreover, the limit ring can also achieve radial limitation at the same time to prevent friction on the threads on the fixed shaft 4 during the rotation of the crank arm.

[0015] Furthermore, two adjacent pay-off units are arranged alternately with each other, and a guide module installed on the pay-off frame is arranged above each of the plurality of pay-off units.

[0016] After adopting the above further structure, the raw material line that emerges from the traction can be guided to the desired output direction through the guiding module.

[0017] Furthermore, the guide module includes a fixed frame installed on the wire pay-off frame, a guide wheel is installed on the fixed frame, a connecting sleeve is provided on one side of the fixed frame, a connecting column is passed through the connecting sleeve, a fastening bolt is threadedly connected to the side of the connecting sleeve, and a guide ring is installed at the lower end of the connecting column.

[0018] After adopting the above-mentioned further structure, the raw material line first passes through the guide assembly, and then passes through the guide ring and the guide wheel. The guide ring can adjust the height by loosening the fastening bolts, thereby adjusting the output inclination of the raw material line. The raw material line can further reduce the contact with the pay-off wheel during transportation, thereby reducing the scratching of the raw material line. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

When the raw material line is pulled out, the pay-off wheel 6 can be pulled to rotate, thereby driving the conical table 5 to rotate synchronously around the fixed axis 4, thereby improving the rotation smoothness of the pay-off wheel 6 and preventing the wheel from getting stuck and causing the line to break. At the same time, the guide assembly can guide the raw material line to the outside of the pay-off wheel for pulling, thereby preventing the raw material line from contacting the edge of the pay-off wheel 6 and causing scratches, thereby reducing the phenomenon of production interruptions and reducing production efficiency.

[0027] It is worth mentioning that the inner wall of the pay-off wheel 6 can also be connected to the middle part of the fixed shaft 4 through a bearing, making the structure more compact.

[0028] See also Figure 2 and Figure 3 As shown, the limiting assembly of this embodiment includes a limiting plate 8, a threaded section 7 is provided on the upper outer wall of the fixed shaft 4, the limiting plate 8 is threadedly connected to the threaded section 7, and a plurality of rollers 9 distributed in a circumference are installed on the lower end surface of the limiting plate 8, and the rollers 9 abut against the upper surface of the pay-off wheel 6; the limiting plate 8 can be easily removed from the fixed shaft 4 to facilitate the replacement of the pay-off wheel 6, and after the pay-off wheel 6 is clamped between the conical table 5 and the limiting plate 8, the pay-off wheel 6 and the limiting plate 8 are rollingly connected through the rollers 9 to prevent the limiting plate 8 from jamming the pay-off wheel 6.

[0029] The guide assembly of this embodiment includes a curved arm 10 located at the upper end of the limit plate 8, one end of the curved arm 10 is sleeved on the threaded segment 7, and the other end is equipped with a guide ring 11.

The upper end of the curved arm 10 is provided with a pressure cover 13, and the pressure cover 13 is threadedly connected to the threaded segment 7; one end of the curved arm 10 close to the guide ring 11 extends to the outside of the pay-off wheel 6, so that the raw material line passes through the guide ring 11.
