Embodiment Construction
[0020] The embodiment of printer charging roller automatic detection machine of the present invention: as Figure 1-4 As shown, it includes a frame 1 and a detection mechanism installed on the frame 1, a feeding mechanism, a discharging mechanism and a sorting mechanism.
[0021] The detection mechanism includes a detection base 18 slidingly assembled on the frame 1 along the front and rear direction of the frame 1. A detection push cylinder 2 is installed on the front of the detection base 18. Hinged so that under the action of the detection push cylinder 2, the detection base 18 is driven to move back and forth along the front and rear directions of the frame 1. The left and right ends of the detection base 18 are respectively fixed with detection compression cylinders 4, and the ends of the piston rods of the two detection compression cylinders 4 are fixed with detection compression brackets 5, and the left and right ends of the detection compression brackets 5 are respecti...

The invention discloses an automatic detecting machine for a charging roller of a printer. The automatic detecting machine comprises a frame, a detecting mechanism and a loading mechanism, wherein the detecting mechanism and the loading mechanism are mounted on the frame; the detecting mechanism comprises a detecting base and a first driving device which drives the detecting base to move; a detecting pressing bracket and a second driving device which drives the detecting pressing bracket to move are arranged on the detecting base; U-shaped slots are correspondingly arranged on two supporting plates of the detecting pressing bracket; a high-voltage detecting conductive roller is rotatably assembled on the frame and above the detecting pressing bracket; the loading mechanism comprises a loading assembling embedded block and a third driving device which drives the loading assembling embedded block to rotate; a loading groove is arranged above the loading assembling embedded block; the loading groove is provided with a discharging port; the charging roller of the printer can horizontally slide from the discharging port; the loading assembling embedded block is provided with an arc surface in sliding clearance fit with the discharging port; and a receiving groove is arranged on the arc surface. When the automatic detecting machine is applied to a production line, the processes from loading to detecting are full-automatically completed, so that the labor intensity of workers is reduced and the working efficiency is increased.
Description
technical field [0001] The invention relates to a device for automatically detecting the resistance of a charging roller on a printer charging roller production line. Background technique [0002] The printer charging roller is composed of a metal core and an elastic rubber coated on the metal core. It is a part that charges the photoconductive drum of the printer. The quality of the electrostatic latent image on the surface of the photoconductive drum is an important factor that affects the quality of the printed product. The quality of the electrostatic latent image The quality of the photoconductor drum is also related to the level and uniformity of the potential on the surface of the photoconductor, that is, it has an important relationship with the quality of the charge. Therefore, when charging the photoconductor drum, the charge on the surface of the photoconductor drum should be evenly distributed and reach the required surface potential. This requires that the resis...
