Description

Technical Field

[0001] This application relates to the field of printer manufacturing, and in particular to a surface treatment device for conductive rubber rollers used in printers. Background Technology

[0002] Conductive rubber rollers are an important component in printers, commonly used in laser printers and digital copiers. Their main function is to provide a uniform charge to the surface of the photosensitive drum so that an electrostatic latent image can be formed during the printing process. Conductive rubber rollers are usually composed of a metal core and conductive rubber covering the metal core.

[0003] An existing Chinese patent (publication number: CN212638805U) mentions a charging roller surface treatment device, which includes a cleaning tank, a plurality of support rods on the cleaning tank, a lifting frame suspended from the support rods, a cleaning roller assembly on the lifting frame, a conveyor chain on the cleaning tank perpendicular to the cleaning roller assembly, a clamping component on the conveyor chain, and a section of the conveyor chain passing between the lifting frame and the bottom wall of the cleaning tank, which has the effect of efficiently and automatically cleaning impurities on the surface of the charging roller.

[0004] However, in actual operation, when using the clamping assembly to clamp and fix the rubber rollers and then tilting them, the operator needs to place the rubber rollers one by one between the top rod and the clamping head, and then clean the rubber rollers. Although cleaning the rubber rollers is convenient, fixing and removing the rubber rollers one by one each time is quite troublesome. Utility Model Content

[0005] The purpose of this application is to solve the problem mentioned in the background art that the processing personnel need to place the rubber rollers one by one between the top rod and the clamping head, and then clean the rubber rollers. Although the process of cleaning the rubber rollers is convenient, it is still quite troublesome to fix and remove the rubber rollers one by one each time. This application provides a surface treatment device for conductive rubber rollers for printers.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A surface treatment device for conductive rubber rollers for printers includes a spray cleaning chamber, a drying chamber on one side of the spray cleaning chamber, a support frame on the spray cleaning chamber and the drying chamber, the support frame passing through the spray cleaning chamber and the drying chamber, a quick loading mechanism on the support frame, and a unloading mechanism at one end of the support frame.

[0008] By adopting the above technical solution, several rubber rollers are placed in the quick-feeding mechanism on the support frame. Then, the quick-feeding mechanism drives the rubber rollers to move sequentially on the support frame, allowing several rubber rollers to pass through the spray tilting chamber and the drying chamber in turn. The unloading mechanism collects the rubber rollers that have been processed, and then the processing personnel transfer the rubber rollers away. This reduces the trouble of cleaning personnel having to place and fix the rubber rollers one by one, and at the same time, it provides a buffer for the unloading operation time of the processing personnel, reducing the possibility of the rubber rollers falling due to untimely unloading.

[0009] Furthermore, the quick feeding mechanism includes a feeding hopper disposed on one side of the support frame. The feeding hopper is inclined, and two symmetrical support legs are fixed on one side of the feeding hopper. The side of the feeding hopper away from the support legs is located above the support frame. A conveying assembly is disposed between the feeding hopper and the support frame.

[0010] By adopting the above technical solution, several rubber rollers are placed into the feeding hopper, and then the rubber rollers in the feeding hopper fall into the conveying component in sequence. The conveying component drives the rubber rollers through the spray cleaning chamber and the drying chamber in sequence, which can facilitate the feeding of rubber rollers, reduce the trouble of handling personnel to place and fix the rubber rollers one by one, and improve the efficiency of rubber roller processing.

[0011] Furthermore, the conveying assembly includes two support rollers symmetrically rotatably connected to the support frame. Each of the two support rollers has two symmetrical gears fixed on it. A conveying chain is connected between the gears on the two support rollers. A drive motor is fixed on the support frame. The output end of the drive motor passes through the support frame and is fixedly connected to one of the support rollers.

[0012] By adopting the above technical solution, the drive motor drives the support roller, the support roller drives the gear, and the gear drives the conveyor chain to move in the direction of the spray tilting chamber and the drying chamber, thereby making it convenient for the conveyor chain to drive the rubber roller.

[0013] Furthermore, several evenly distributed conveyor blocks are fixed on the conveyor chain.

[0014] By adopting the above technical solution, the two ends of the rubber roller fall into the gap between adjacent conveyor blocks on the conveyor chain, thereby enabling the conveyor blocks to restrict the rubber roller and facilitate the movement of the rubber roller.

[0015] Furthermore, two symmetrical conveying guide plates are fixed on the support frame. The conveying guide plates correspond to the conveying blocks. The conveying guide plates are provided with feeding ports corresponding to the feeding hoppers. The feeding hoppers are fixedly connected to the conveying guide plates.

[0016] By adopting the above technical solution, the conveyor guide plate restricts both ends of the rubber roller, thereby reducing the possibility of the rubber roller falling off between adjacent conveyor blocks.

[0017] Furthermore, the end of the conveying guide plate away from the hopper is arc-shaped.

[0018] By adopting the above technical solution, under the constraint of the arc shape at the end, when the adjacent conveyor blocks are completely facing downwards, the rubber roller falls from between the adjacent conveyor blocks, thereby making it easy for the rubber roller to move out from between the adjacent conveyor blocks.

[0019] Furthermore, the feeding mechanism includes two symmetrical feeding frames located at the end of the feeding frame away from the feeding hopper. Each of the two feeding frames has a feeding groove. The two feeding frames are wavy. A baffle plate is fixed between the two feeding frames. The baffle plate is located at the end of the feeding frame away from the support frame. Each of the two feeding frames has a material receiving port.

[0020] By adopting the above technical solution, the rubber roller falls from between the conveyor blocks into the unloading frame. Then, under its own weight and the inclination of the unloading frame, the rubber roller moves along the unloading grooves opened on the two unloading frames. Then the unloading frame moves to the position of the baffle plate, which can buffer the unloading operation time of the processing personnel and reduce the possibility of the rubber roller falling due to untimely unloading.

[0021] Furthermore, a cushioning rubber pad is fixed to the barrier plate.

[0022] By adopting the above technical solution, the unloading rack moves to the position of the baffle plate, and at the same time, the rubber roller hits the buffer rubber pad on the baffle plate, thereby reducing the possibility of the rubber roller hitting the baffle plate.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. This application involves placing several rubber rollers into a feeding hopper, with both ends of the rubber rollers abutting against the hopper. The inclined surface in the feeding hopper causes the rubber rollers to move towards the discharge port on the hopper. The two ends of the rubber rollers fall from the feeding port of the conveyor guide plate and enter the gap between adjacent conveyor blocks of the conveyor chain. The drive motor is started, which drives the support roller, which in turn drives the gear, which in turn drives the conveyor chain. The two conveyor chains move synchronously, causing the conveyor blocks to move. The conveyor blocks then move the rubber rollers into the spray tilting chamber and the drying chamber. After one rubber roller is moved, the next rubber roller continues to move from the feeding hopper to the gap between the adjacent conveyor blocks, and then moves the rubber roller. When the conveyor blocks on the conveyor chain move the rubber rollers, the conveyor guide plate restricts the two ends of the rubber rollers, reducing the possibility of the rubber rollers falling off between adjacent conveyor blocks. This achieves the purpose of facilitating the feeding of rubber rollers, reducing the trouble of handling personnel placing and fixing each rubber roller individually, and improving the efficiency of rubber roller processing.

[0025] 2. In this application, after the rubber rollers are cleaned, they fall from between the conveyor blocks into the unloading frame under the drive of the conveyor blocks and the guidance of the conveyor guide plate. Then, under the action of their own weight and the inclination of the unloading frame, the rubber rollers move along the unloading grooves opened on the two unloading frames. Then, the unloading frame moves to the position of the baffle plate, and at the same time, the rubber rollers hit the buffer rubber pads on the baffle plate. Then, the processing personnel use the material removal port on the unloading frame to remove the rubber rollers. This achieves the purpose of buffering the unloading operation time of the processing personnel and reducing the possibility of the rubber rollers falling due to untimely unloading.

[0032] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0033] This application discloses a surface treatment device for conductive rubber rollers used in printers.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A surface treatment device for conductive rubber rollers for printers includes a spray cleaning chamber 1, a drying chamber 2 is provided on one side of the spray cleaning chamber 1, a support frame 3 is provided on the spray tilting chamber and the drying chamber 2, the support frame 3 passes through the spray cleaning chamber 1 and the drying chamber 2, a quick feeding mechanism 4 is provided on the support frame 3, and a discharging mechanism 5 is provided at one end of the support frame 3.

[0035] When performing surface treatment on conductive rubber rollers, several rubber rollers are first placed into the quick-feeding mechanism 4 on the support frame 3. Then, the quick-feeding mechanism 4 drives the rubber rollers to move sequentially on the support frame 3, allowing the rubber rollers to pass through the spray tilting chamber and drying chamber 2 in turn to complete the cleaning of the rubber roller surface. Then, the quick-feeding mechanism 4 continues to drive the rubber rollers to move, allowing the rubber rollers to fall from the quick-feeding mechanism 4 into the unloading mechanism 5. The unloading mechanism 5 collects the treated rubber rollers, and then the processing personnel transfer the rubber rollers away. By placing several rubber rollers together on the quick-feeding mechanism 4 and then letting the quick-feeding mechanism 4 drive the rubber rollers to move sequentially and fall into the unloading mechanism 5, the trouble of cleaning personnel having to place and fix the rubber rollers one by one can be reduced. At the same time, it can buffer the unloading operation time of the processing personnel and reduce the possibility of the rubber rollers falling due to untimely unloading.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The quick feeding mechanism 4 includes a feeding hopper 41 set on one side of the support frame 3. The feeding hopper 41 is set at an inclination. Two symmetrical support legs 42 are fixed on one side of the feeding hopper 41. The side of the feeding hopper 41 away from the support legs 42 is located above the support frame. A conveying assembly 43 is set between the feeding hopper 41 and the support frame 3.

[0037] In addition, the conveying assembly 43 includes two support rollers 431 symmetrically rotatably connected to the support frame 3. Two symmetrical gears 432 are fixed on each of the two support rollers 431. A conveying chain 433 is connected between the gears 432 on the two support rollers 431. A drive motor is fixed on the support frame 3. The output end of the drive motor passes through the support frame 3 and is fixedly connected to one of the support rollers 431.

[0038] Furthermore, several evenly distributed conveyor blocks 434 are fixed on the conveyor chain 433.

[0039] Furthermore, two symmetrical conveying guide plates 435 are fixed on the support frame 3. The conveying guide plates 435 correspond to the conveying blocks 434. The conveying guide plates 435 are provided with feeding ports corresponding to the feeding hoppers 41. The feeding hoppers 41 are fixedly connected to the conveying guide plates 435.

[0040] When feeding conductive rubber rollers, several rubber rollers are placed in the feeding hopper 41, with both ends of the rubber rollers abutting against the inside of the feeding hopper 41. The inclined surface in the feeding hopper 41 causes the rubber rollers to move towards the discharge port on the feeding hopper 41. The two ends of the rubber rollers fall from the feeding port of the conveyor guide plate 435 and enter the gap between the adjacent conveyor blocks 434 of the conveyor chain 433. The drive motor is started, and the drive motor drives the support roller 431. The support roller 431 drives the gear 432, and the gear 432 drives the conveyor chain 433 to move. The two conveyor chains 433 move synchronously, driving the conveyor blocks 434 to move. The conveyor blocks 434 drive the rubber rollers to move into the spray inclined chamber and the drying chamber 2. After the previous rubber roller is... After the first rubber roller moves away, the next rubber roller continues to move from the hopper 41 to the gap between the adjacent conveyor blocks 434. Then, it moves along the conveyor blocks 434 on the conveyor chain 433. When the conveyor blocks 434 move the rubber roller, the conveyor guide plate 435 restricts both ends of the rubber roller to reduce the possibility of the rubber roller falling off between the adjacent conveyor blocks 434. By placing several rubber rollers into the hopper 41, and then letting the rubber rollers fall into the gap between the moving adjacent conveyor blocks 434 in sequence, the rubber rollers pass through the spray cleaning chamber 1 and the drying chamber 2 in sequence. This makes it easier to load the rubber rollers, reduces the trouble of having to place and fix each rubber roller individually, and improves the efficiency of rubber roller processing.

[0041] Reference Figure 2 and Figure 3 The end of the conveyor guide plate 435 away from the feeding hopper 41 is arc-shaped.

[0042] When the conveyor chain 433 moves the cleaned rubber roller to the end of the conveyor guide plate 435, under the constraint of the arc shape of the end, when the adjacent conveyor blocks 434 are completely facing downwards, the rubber roller falls from between the adjacent conveyor blocks 434. By setting one end of the conveyor guide plate 435 to be arc-shaped, it is easy to move the rubber roller out from between the adjacent conveyor blocks 434.

[0043] Reference Figure 1 , Figure 2 and Figure 4 The feeding mechanism 5 includes two symmetrical feeding racks 51 located at the end of the feeding rack 51 away from the feeding hopper 41. Each feeding rack 51 has a feeding groove. The two feeding racks 51 are wavy. A baffle plate 53 is fixed between the two feeding racks 51. The baffle plate 53 is located at the end of the feeding rack 51 away from the support frame 3. Each feeding rack 51 has a material receiving port 52.

[0044] In addition, a buffer rubber pad 54 is fixed on the baffle plate 53.

[0045] After the rubber rollers are cleaned, driven by the conveyor block 434 and guided by the conveyor guide plate 435, the rubber rollers fall from between the conveyor blocks 434 into the unloading rack 51. Then, under the action of their own weight and the inclination of the unloading rack 51, the rubber rollers move along the unloading grooves opened on the two unloading racks 51. Then the unloading rack 51 moves to the position of the baffle plate 53, and at the same time, the rubber rollers hit the buffer rubber pads 54 on the baffle plate 53. Then, the processing personnel use the material removal port 52 on the unloading rack 51 to remove the rubber rollers. By allowing the cleaned rubber rollers to move along the unloading rack 51, the rubber rollers can be temporarily stopped on the unloading rack 51, thereby buffering the unloading operation time of the processing personnel and reducing the possibility of the rubber rollers falling due to untimely unloading.

[0046] Working principle: During the surface treatment of conductive rubber rollers, several rubber rollers are placed in the feeding hopper 41, with both ends of the rubber rollers abutting against the inside of the feeding hopper 41. The inclined surface in the feeding hopper 41 causes the rubber rollers to move towards the discharge port on the feeding hopper 41. The two ends of the rubber rollers fall from the feeding port of the conveyor guide plate 435 and enter the gap between the adjacent conveyor blocks 434 of the conveyor chain 433. The drive motor is started, which drives the support roller 431. The support roller 431 drives the gear 432, which drives the conveyor chain 433 to move. The two conveyor chains 433 move synchronously, driving the conveyor blocks 434 to move. The conveyor blocks 434 drive the rubber rollers to move into the spray inclined chamber and the drying chamber 2. After the previous rubber roller is moved away, the next rubber roller continues to move from the feeding hopper 41. The rubber roller moves into the gap between the adjacent conveyor blocks 434 and then moves. When the conveyor blocks 434 on the conveyor chain 433 move the rubber roller, the conveyor guide plate 435 restricts both ends of the rubber roller to reduce the possibility of the rubber roller falling off between the adjacent conveyor blocks 434. After the rubber rollers are cleaned, under the drive of the conveyor blocks 434 and the guidance of the conveyor guide plate 435, the rubber roller falls from between the conveyor blocks 434 into the unloading rack 51. Then, under its own weight and the inclination of the unloading rack 51, the rubber roller moves along the unloading grooves opened on the two unloading racks 51. Then the unloading rack 51 moves to the position of the baffle plate 53. At the same time, the rubber roller hits the buffer rubber pad 54 on the baffle plate 53. Then the processing personnel use the material removal port 52 on the unloading rack 51 to remove the rubber roller.
