Common air covering machines generally include an original yarn frame, a spandex feeding device, a drafting feeding device (main traction roller), a wire guide, an air covering device, a main traction device, a winding device (winding roller, traverse groove drum) and an oiling device. During the working process, the spandex yarn is sent out through the spandex feeding device with a certain drafting multiple, and then reaches the drafting feeding device through the wire guide. At the same time, the cotton nylon or polyester on the movable original yarn frame above the frame also enters the drafting feeding device through the wire guide. Subsequently, the spandex enters the air covering device through the spandex yarn monitor and cotton nylon for network covering, enters the main traction roller, and then enters the high-speed winding device through the wire guide wheel and the oiling device, and is wound up through the traverse groove drum to realize the winding and collection of the covered yarn.

[0004] In the prior art, the tension auxiliary device of the coated wire machine usually places the coated wire into a wire groove connected to the top of the adjusting rod, and then manually adjusts the height of the adjusting rod to adjust the tension of the coated wire, and finally inserts the positioning pin into the limit groove to limit the height of the adjusting rod. However, this method requires full monitoring of the coated wire machine during its use, which greatly increases the workload of the workers and makes it easy for the workers to fail to adjust the tension of the coated wire machine in time due to fatigue, thereby affecting the quality of the finished product.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides a technical solution: a tension auxiliary device for a coated wire machine, including a base 1, an adjusting component 2 is fixedly connected to the top of the base 1, a plurality of guide frames 3 are fixedly connected to the top of the base 1 located on the right side of the adjusting component 2, a detection component 4 is fixedly connected to the top of the base 1 located between two guide frames 3, and a limiting component 6 is arranged in the guide frame 3.

[0026] By changing the distance between the two limiting rings 62 in the limiting component 6, the coated wire can be limited according to the radius of the coated wire. When the tension of the coated wire changes, the coated wire will exert pressure on the extrusion wheel in the detection component 4. In conjunction with the extrusion frame 44, the slide rail 43 and the return spring 46, the pressure between the support rod 45 and the pressure sensor 42 can be changed according to the change in tension. When the pressure sensor 42 detects that the pressure is higher or lower than the preset value, it will transmit a signal to the controller 41. The controller 41 will automatically adjust the tension of the coated wire by adjusting the electric push rod 21 and the adjustment frame 22 in the adjustment component 2.

[0027] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides a technical solution: the adjustment component 2 includes an electric push rod 21 fixedly connected to the top of the base 1, the telescopic end of the electric push rod 21 is fixedly connected to the adjustment frame 22, and the adjustment wheel is rotatably connected in the adjustment frame 22. When the pressure sensor 42 detects that the pressure is higher or lower than the preset value, it will transmit a signal to the controller 41, and the controller 41 will start the electric push rod 21, and the electric push rod 21 will drive the adjustment wheel in the adjustment frame 22 to rise and fall, so as to automatically adjust the tension of the coated wire.

[0028] The detection assembly 4 includes a controller 41 fixedly connected to the base 1. The base 1 is located between the two guide frames 3 and is fixedly connected to a pressure sensor 42. The top of the base 1 is located at the front and rear ends of the pressure sensor 42 and is fixedly connected to a slide rail 43. An extrusion frame 44 is slidably connected in the slide rail 43. An extrusion wheel is rotatably connected in the extrusion frame 44. A push rod 45 is fixedly connected to the bottom of the extrusion frame 44. A reset spring 46 is fixedly connected to the bottom of the slide rail 43. The reset spring 46 is fixedly connected to the extrusion frame 44. When the tension of the coated wire changes, the coated wire will apply pressure to the extrusion wheel and push the extrusion frame 44 to move up and down along the slide rail 43 and squeeze the reset spring 46, which in turn drives the push rod 45 to rise and fall, so that the distance between the push rod 45 and the pressure sensor 42 can be adjusted in real time according to the change of tension, thereby changing the size of the pressure between the push rod 45 and the pressure sensor 42. The pressure sensor 42 will monitor the size of the pressure of the push rod 45 in real time.

[0029] A damping rod 47 is arranged in the return spring 46, and the damping rod 47 is fixedly connected to the extrusion frame 44. By arranging the damping rod 47, the extrusion frame 44 can be prevented from rebounding.

[0030] An inspection door 5 is hinged at the front end of the base 1, and a handle groove is provided at the front end of the inspection door 5. The inspection door 5 is provided to facilitate inspection of the controller 41 arranged in the base 1.

[0031] The limiting assembly 6 includes a support rod 61 rotatably connected to the guide frame 3, two limiting rings 62 are slidably connected to the surface of the support rod 61, and limiting holes are provided on the surface of the support rod 61 and the surface of the limiting ring 62, and the limiting bolts are threadedly connected in the limiting holes. First, the coated wire is placed between the two limiting rings 62 located on the surface of the support rod 61, and then the two limiting rings 62 are moved in a direction away from the coated wire according to the radius of the coated wire. After the two limiting rings 62 are moved to a suitable position, the limiting bolts are screwed into the limiting holes to limit the coated wire, thereby preventing the coated wire from deviating during the conveying process.

[0032] The radius of the limiting ring 62 is greater than the radius of the support rod 61, and a scale 7 is fixedly connected to the surface of the support rod 61. The scale 7 is provided to facilitate rapid adjustment of the position of the limiting ring 62 according to the radius of the coated wire.

[0033] The bottom end of the base 1 is fixedly connected with an anti-skid pad 8, and the bottom end of the anti-skid pad 8 is fixedly connected with an anti-skid pattern. The anti-skid pad 8 can increase the friction between the device and the placement surface, thereby improving the stability of the device when placed.

[0034] Specific implementation method: first, place the coated wire between the two limiting rings 62 located on the surface of the support rod 61, and then move the two limiting rings 62 in the direction away from the coated wire according to the radius of the coated wire. After the two limiting rings 62 move to a suitable position, screw the limiting bolts into the limiting holes to limit the coated wire, thereby preventing the coated wire from deviating during the transportation process. Then, pass the coated wire through the top of the adjusting wheel connected in the adjusting frame 22, the bottom of the guide wheels connected in the two guide frames 3, and the top of the extrusion wheel connected in the extrusion frame 44. When the tension of the coated wire changes, the coated wire will exert pressure on the extrusion wheel and push the extrusion wheel to move. The pressure frame 44 moves up and down along the slide rail 43 and squeezes the reset spring 46, which in turn drives the push rod 45 to rise and fall, so that the distance between the push rod 45 and the pressure sensor 42 can be adjusted in real time according to the change of tension, thereby changing the pressure between the push rod 45 and the pressure sensor 42. The pressure sensor 42 will monitor the pressure of the push rod 45 in real time. When the pressure sensor 42 detects that the pressure is higher or lower than the preset value, it will transmit a signal to the controller 41. The controller 41 will start the electric push rod 21, and the electric push rod 21 will drive the adjustment wheel in the adjustment frame 22 to rise and fall, thereby automatically adjusting the tension of the coated wire.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
