[0002] The developer roller is an important component in the printing device. The developer roller can provide toner to the surface of the photosensitive drum, thereby converting the electrostatic latent image on the surface of the photosensitive drum into a visible image.

[0003] In the production process of the developing roller, in order to enhance the bonding force between the metal core shaft and the conductive rubber outer layer, it is necessary to coat the surface of the core shaft with glue before assembling the core shaft and the conductive rubber layer, and the developing roller needs to be preheated before coating with glue, so as to facilitate the processing efficiency in the subsequent coating process. However, in the process of preheating the developing roller during transportation, the existing device usually requires an adapter to install the chain for transmitting the developing roller, but the transmission chain is prone to loosening and jumping when meshing with the gears, and is therefore prone to the risk of being out of gear meshing.

[0026] refer to Figures 1 to 4 The setting of the first cross bar and the first cross column 2 can better facilitate the stable assembly of the overall device, thereby improving the bearing capacity of the overall device and improving the stability of the overall device. The setting of the cross plate 4 and the second cross column 5 can better facilitate the installation of the transmission device and the clamping device, and can improve the stability of the overall device.

[0027] The side surfaces of the two groups of supporting legs 1 that are close to each other are fixedly connected with a third horizontal column 7, and the lower end of each supporting leg 1 is fixedly connected with a supporting foot 8. By setting the third horizontal column 7, the stability of the overall device can be better improved, thereby preventing the overall device from shaking when preheating the developing roller and affecting the transportation of the developing roller. The setting of the supporting foot 8 can better facilitate the placement and movement of the overall device, and can greatly improve the friction and contact force between the overall device and the ground, thereby greatly improving the stability of the overall device.

[0029] The output end of each electric push rod 10 passes through the fixed frame 9 on the same side and is fixedly connected to a clamping plate 11, and the clamping plate 11 is made of flexible material.

By setting a dual-output shaft motor 604, the dual-output shaft motor 604 can operate intermittently, so that the developing roller in the preheating area can be uniformly preheated, and the subsequent gluing process can be intermittently operated for the taking time of the developing roller.

[0033] The upper surfaces of the two left second horizontal columns 5 are fixedly connected with a mounting plate 6012, and the left side of the mounting plate 6012 is fixedly connected with a connecting plate 6013, and the upper surface of the connecting plate 6013 is fixedly connected to the bottom surface of the dual-output shaft motor 604. By setting the mounting plate 6012, the connecting plate 6013 can be easily installed and fixed, and the dual-output shaft motor 604 can be fixed by the connecting plate 6013, thereby preventing the dual-output shaft motor 604 from rotating and shaking during operation, greatly improving the transmission effect of the dual-output shaft motor 604 on the transmission components, and greatly improving the work of the overall device on the transmission of the developing roller.

[0034] Example 2

[0035] like Figure 1 to Figure 4As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a fixing plate 605 is fixedly connected to one side of the two second horizontal columns 5 on the left side that are close to each other, and a hydraulic cylinder 606 is installed on the bottom surface of the fixing plate 605, and the bottom surfaces of the two second horizontal columns 5 on the left side are fixedly connected to guide plates 607, and the outer surfaces of the guide plates 607 are provided with guide grooves 608, and the inner walls of the two guide grooves 608 are provided with slidable adjustment rods 609, and the outer surfaces of the adjustment rods 609 are hinged to the output ends of the hydraulic cylinders 606, and the outer surfaces of the adjustment rods 609 are rotatably connected to two second gears 6010, and two chains 6011 are provided on the upper part of the supporting leg 1, and the chains 6011 are meshed with the first gear 603 and the second gear 6010.

[0036] In this embodiment, reference Figures 1 to 4 When adjusting the tightness between the chain 6011 and the first gear 603 and the second gear 6010, by starting the hydraulic cylinder 606, the output end of the hydraulic cylinder 606 drives the adjusting rod 609 and the two second gears 6010 to descend under the limiting action of the guide groove 608, so as to adjust the tightness of the chain 6011, thereby avoiding the chain 6011 from jumping when the first gear 603 rotates, and avoiding affecting the transportation of the developing roller.

[0037] Two telescopic sleeves 6014 are fixedly connected to the bottom surface of the fixed plate 605, and the lower end of the telescopic sleeve 6014 is hinged to the outer surface of the adjusting rod 609.

[0039] Working principle: When preheating and transporting the developing roller, firstly, the developing roller storage component is placed on the chain 6011, and the developing roller storage and transportation component is stably placed and pushed by the placement block 12 and the push plate 13. After placement, the electric push rod 10 is started, and the output end of the electric push rod 10 pushes the placement block 12 to clamp the developing roller storage and transportation component, thereby adjusting the horizontal position of the developing roller storage and transportation component. At this time, the dual-output shaft motor 604 is started, and the two output shafts of the dual-output shaft motor 604 drive the first gear 603 to rotate through the rotating rod 602, so that the first gear 603 drives the chain 6011 to transmit, and then it can The developing roller storage and transportation component is transported by chain 6011, and the developing roller is transported to the preheating area for preheating. After the preheating is completed, the developing roller can be transported to the subsequent gluing process for gluing. When the chain 6011 is easily loosened after installation and jumps when the first gear 603 rotates, the hydraulic cylinder 606 is started, and the output end of the hydraulic cylinder 606 drives the adjusting rod 609 and the two second gears 6010 to descend under the limiting action of the guide groove 608, so that the tightness of the chain 6011 can be adjusted, thereby avoiding the chain 6011 from jumping when the first gear 603 rotates, and avoiding affecting the transportation of the developing roller.
