The working principle of the conductive roller is based on the change in contact resistance between the roller and the conductive material to achieve signal transmission. When the object moves, the roller rotates, and at the same time, it also drives the movement of the conductive material, causing the contact resistance value between the roller and the conductive material to change.

A placement groove 202 is opened on the top inner wall of the mounting seat 201, and traction springs 204 are arranged at the bottom of the inner wall of the top four corners of the mounting seat 201. A pressure plate 206 is arranged on the top of the four traction springs 204, and fixing bolts 207 are arranged between the top four corners of the pressure plate 206 and the top four corners of the inner wall of the mounting seat 201. The brush can be installed and fixed through the placement groove 202, and the pressure plate 206 can press the brush under the elastic force of the traction spring 204. The fixing bolts 207 can reinforce the pressure plate 206 so that the brush can remain stable inside the placement groove 202.

[0029] In order to conveniently install the conductive ring 104 and keep it stable on the outside of the cathode roller 101, as shown in FIG. Figure 2 and Figure 3 As shown, the roller body 1 includes a cathode roller 101, and connecting rods 102 are fixedly installed on the outer sides of both ends of the cathode roller 101. A fixing hole 103 is opened on the inner wall of the connecting rod 102 on the side away from the cathode roller 101, and a conductive ring 104 is movably sleeved on the outer side of the connecting rod 102. A fastening pin 105 is threadedly inserted on the inner wall of the fixing hole 103, and the screw head part of the fastening pin 105 is in contact with the conductive ring 104. The diameter of the screw head part of the fastening pin 105 is larger than the diameter of the connecting rod 102, and the diameter of the screw head part of the fastening pin 105 is smaller than the diameter of the conductive ring 104. The conductive ring 104 is sleeved on the outer side of the connecting rod 102 so that it can be fixed to the outer side of the cathode roller 101. The conductive ring 104 can be reinforced by the threaded connection between the fastening pin 105 and the fixing hole 103, and the conductive ring 104 can be prevented from detaching from the outer side of the connecting rod 102.

[0030] In order to make the installation mechanism 2 convenient for installing brushes of different sizes, Figure 2 and Figure 4As shown, the outer walls of the two ends of the cathode roller 101 close to the connecting rod 102 are rotatably connected to the inner wall at the bottom of the mounting seat 201, and the inner walls of the four corners of the top of the mounting seat 201 are provided with movable grooves 203. The bottoms of the inner walls of the four movable grooves 203 are respectively fixedly connected to four traction springs 204, and sliders 205 are fixedly installed at both ends of the outer walls on both sides of the pressure plate 206. The bottoms of the four sliders 205 are respectively fixedly connected to the four traction springs 204, and the outer walls of the four sliders 205 are respectively movably connected to the inner walls of the four movable grooves 203. The tops of the inner walls at the four corners of the top of the mounting seat 201 are respectively threadedly connected to the outer walls of four fixing bolts 207, and the bottoms of the four fixing bolts 207 penetrate the inner walls of the tops of adjacent movable grooves 203 and are in contact with the tops of adjacent sliders 205. The movable groove 203 can limit the movement of the slider 205, so that the pressure plate 206 can be easily moved on the inner side of the top of the mounting seat 201, so that the mounting mechanism 2 can install brushes of different sizes.

[0031] In order to install the brush stably, Figure 2 and Figure 4 As shown, the front vertical section of the placement groove 202 is set to a U-shaped structure, and the diameter of the arc surface at the bottom of the pressure plate 206 is the same as the diameter of the bottom of the placement groove 202. The brush can be installed and fixed through the placement groove 202 and the pressure plate 206.

After the conductive ring 104 is sleeved, the threaded connection between the fastening pin 105 and the fixing hole 103 can be used to reinforce and limit the conductive ring 104, so that the conductive ring 104 can be prevented from being separated from the outer side of the connecting rod 102. At the same time, the brush is inserted into the placement groove 202 at the top of the mounting seat 201, and the chicken pressure plate 206 generates an upward thrust, so that it moves upward along the inner wall of the four movable grooves 203 through the slider 205, thereby making the four traction springs 204 Extending upward, when the brush is placed inside the placement slot 202, the pressure plate 206 can press and fix the top of the brush under the elastic force of the traction spring 204, and then use the fixing bolt 207 to penetrate the top inner wall of the movable slot 203 and abut against the top of the adjacent slider 205, so that the pressure plate 206 can stably press the brush, thereby keeping the brush stable on the inner wall of the placement slot 202, and then the setting of the brush can reduce the wear of the conductive ring 104, thereby extending the service life of the roller body 1. This embodiment specifically solves the problem in the prior art that the conductive roller cannot conveniently install brushes of different sizes during use, which affects the service life of the conductive roller.
