Description

Technical Field

[0001] This utility model relates to the field of roller coating, specifically to an automatic roller coating equipment. Background Technology

[0002] The conductive rollers used in existing copiers and laser printers, such as charging rollers and developing rollers, are coated with a layer of conductive coating. In daily life, there are usually three methods for applying this conductive coating: spraying, roller coating, and dip coating. Roller coating and dip coating both have uneven coating film. Spraying is usually chosen for spraying operations.

[0003] Most existing spraying methods involve workers holding a spray gun and uniformly spraying the outer wall of the roller. To prevent cracking caused by excessive thickness in a single spray, multiple thin spraying layers are usually used. This effectively avoids pinholes or cracks caused by excessive thickness in a single spray. However, when dealing with larger rollers, multiple thin spraying layers can seriously affect the overall spraying efficiency and reduce the workload of workers. In addition, spraying large rollers takes a long time, and the spray liquid inside may separate if left to stand for a long time, which will seriously affect the subsequent spraying effect.

[0004] In summary, when dealing with the spraying of large-sized rollers, manual operation will seriously affect the overall spraying efficiency and reduce the workload of the workers. Furthermore, the internal spraying liquid may separate into layers if left to stand for a long time, which will seriously affect the subsequent spraying effect. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an automatic roller spraying device to solve the technical problems that manual operation will seriously affect the overall spraying efficiency, reduce the workload of workers, and prevent the internal spraying liquid from separating when left to stand for a long time, which will seriously affect the subsequent spraying effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic roller coating device, comprising a worktable and a frame, a drive assembly being provided on the top of the frame, a nozzle cooperating with the drive assembly being slidably disposed on the inner wall of the frame in the vertical direction, a placement groove being provided on the top of the worktable within the frame, wherein a placement plate is rotatably disposed within the placement groove, a coating cylinder being disposed within the worktable, wherein a corrugated pipe is connected between the coating cylinder and the nozzle, and a stirring assembly is rotatably disposed within the coating cylinder.

[0007] By adopting the above technical solution, the stepper motor drives the nozzle to slide up and down reciprocally on the inner wall of the frame, while the transmission component drives the roller on the placement plate to rotate. This process realizes automated rotary spraying. The spraying cylinder is equipped with a stirring component that works with the stepper motor. During the spraying process, the stirring component stirs and agitates the spray liquid in the spraying cylinder, effectively preventing the spray liquid in the spraying cylinder from separating during the spraying process and improving the subsequent spraying effect.

[0008] The present invention is further configured such that a reciprocating lead screw is rotatably disposed within the frame, and a lead screw sleeve is slidably disposed on the outer wall of the reciprocating lead screw, wherein one side of the lead screw sleeve is connected to the nozzle.

[0009] Preferably, the reciprocating lead screw is driven to rotate rapidly by the stepper motor. During this process, the lead screw sleeve slides back and forth on the outer wall of the reciprocating lead screw, thereby driving the spray head to move and spray on the inner wall of the frame.

[0010] The present invention is further configured such that the driving component is a stepper motor, which is used to drive the reciprocating lead screw at the output end to rotate.

[0011] Preferably, the stepper motor drives the reciprocating screw to rotate at different speeds, thereby adjusting the spray nozzle to slide and spray at different speeds within the frame. This facilitates the selection of different spraying speeds based on different rollers, improving the overall practicality of the device.

[0012] The present invention is further configured such that the bottom end of the reciprocating lead screw is connected to a transmission mechanism, and the other end of the transmission mechanism is connected to the stirring assembly.

[0013] Preferably, during the rotation of the reciprocating screw by the stepper motor, the stirring component inside the spraying cylinder is driven to rotate by the transmission mechanism, thereby achieving the stirring and mixing of the spraying liquid inside during the spraying process.

[0014] The present invention is further configured such that the stirring assembly includes a stirring rod and a stirring blade, one end of the stirring rod is connected to a transmission mechanism, and is located on the outer wall of the stirring rod and connected to the stirring blade.

[0015] Preferably, during the rotation of the transmission mechanism, the stirring rod drives the stirring blade to stir and agitate inside the spraying cylinder, ensuring that the spraying liquid is fully mixed after a long period of spraying.

[0016] The present invention is further configured such that one end of the stirring rod is connected to a transmission mechanism, and the other end of the stirring rod is connected to the placement plate.

[0017] Preferably, under the action of the transmission mechanism, the stirring rod will also drive the placement plate in the placement trough to rotate, thereby facilitating the all-round spraying of the rollers on the placement plate.

[0018] The present invention is further configured such that the transmission mechanism includes a driving disc, a transmission belt and a driven disc, the driving disc and the driven disc are connected by the transmission belt, one end of the reciprocating screw is connected to the driving disc, and one end of its driven disc is connected to the stirring rod, and the diameter of the driving disc in the transmission mechanism is smaller than the diameter of its driven disc.

[0019] Preferably, during the rotation of the reciprocating screw via the stepper motor, the driving disc at the bottom will rotate. Under the action of the transmission belt, the driven disc will drive the stirring rod to rotate. Since the diameter of the driving disc in the transmission mechanism is smaller than the diameter of its driven disc, when the reciprocating screw drives the driving disc to rotate rapidly, its driven disc will drive the stirring rod to rotate slowly, ensuring that the rollers on the placement plate are in a stable state.

[0020] The present invention is further provided that a curing component is provided on the top of the workbench on one side of the placement plate, and the curing component is detachable.

[0021] Preferably, the curing component facilitates the curing process of the roller body after one side has been sprayed, enabling a multi-layer thin spraying method during the spraying process, which improves the spraying effect on the roller body itself.

[0022] The present invention is further configured such that the inner wall of the frame is provided with a sliding groove for the lead screw sleeve to slide, and the outer wall of the frame is provided with a slot for the bellows to slide.

[0023] Preferably, the groove helps to prevent the lead screw sleeve from rotating along with the reciprocating lead screw during the sliding process, further improving the stability of the lead screw sleeve driving the nozzle to slide within the frame. The groove design also ensures that the bellows can slide stably up and down.

[0024] In summary, the present invention has the following main advantages: This invention features a stepper motor installed at the top of the frame. The stepper motor drives the spray head to slide up and down on the inner wall of the frame. At the same time, the transmission component drives the roller on the placement plate to rotate. This process achieves automated rotary spraying. In conjunction with the curing component on one side, it completes multi-layer thin spraying. When dealing with large rollers, it saves a lot of manpower and resources and improves the overall spraying efficiency. This invention features a spraying cylinder installed inside the workbench, with a stirring component rotatably mounted inside the spraying cylinder in conjunction with a stepper motor. During the spraying process, the stirring component agitates and stirs the spraying liquid inside the spraying cylinder, effectively preventing the spray liquid from separating during the spraying process and improving the subsequent spraying effect.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] Example 1: Please refer to Figures 1-5An automatic roller coating device is shown, comprising a workbench 1, a frame 2, a mixing assembly, a transmission mechanism 13, and a coating mechanism. A stepper motor 5 is installed on the top of the frame 2, and a placement groove 4 is opened inside the frame 2 on the top of the workbench 1. A placement plate 3 is rotatably installed in the placement groove 4. The operator places the roller to be coated on the top of the placement plate 3 and then starts the stepper motor 5 on the top of the frame 2. A reciprocating screw 9 is rotatably installed inside the frame 2, and a screw sleeve 8 is slidably installed on the outer wall of the reciprocating screw 9. One side of the screw sleeve 8 is connected to the nozzle 6. Under the action of the stepper motor 5, the reciprocating screw 9 is driven to rotate rapidly. During this process, the screw sleeve 8 will slide back and forth on the outer wall of the reciprocating screw 9. A coating cylinder 15 is installed inside the workbench 1, and a corrugated pipe 12 is connected between the coating cylinder 15 and the nozzle 6. Under the action of the corrugated pipe 12, the nozzle 6 moves and performs coating work on the inner wall of the frame 2. Furthermore, a transmission mechanism 13 is connected to the bottom end of the reciprocating screw 9, and a stirring component is connected to the other end of the transmission mechanism 13. During the rotation of the reciprocating screw 9 by the stepper motor 5, the stirring component inside the spraying cylinder 15 will be rotated by the action of the transmission mechanism 13, thereby achieving the mixing of the spraying liquid inside during the spraying process, preventing the spraying liquid from separating, and improving the subsequent spraying effect. At the same time, the other end of the stirring component is connected to the placement plate 3. Under the action of the transmission mechanism 13, the stirring component will also drive the placement plate 3 in the placement tank 4 to rotate, thereby facilitating the all-round spraying of the roller on the placement plate 3. Furthermore, a curing component 10 is provided on the top of the workbench 1 on one side of the placement plate 3. The curing component 10 is detachable. Under the action of the curing component 10, it is convenient to cure the roller after spraying on one side, realizing the multi-layer thin spraying method during the spraying process, which improves the spraying effect of the roller itself.

[0030] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The stirring assembly includes a stirring rod 14 and a stirring blade 16. One end of the stirring rod 14 is connected to the transmission mechanism 13, and the stirring blade 16 is located on the outer wall of the stirring rod 14. During the rotation of the transmission mechanism 13, the stirring rod 14 will drive the stirring blade 16 to stir and agitate inside the spraying cylinder 15, ensuring that the spraying liquid is fully mixed after a long period of spraying.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 3The inner wall of the frame 2 is provided with a groove 7 for the lead screw sleeve 8 to slide, and a slot 11 is provided on the outer wall of the frame 2 for the bellows 12 to slide. The groove 7 helps to prevent the lead screw sleeve 8 from rotating with the reciprocating lead screw 9 during the sliding process, which further improves the stability of the lead screw sleeve 8 driving the nozzle 6 to slide in the frame 2. The slot 11 ensures that the bellows 12 can slide up and down stably.

[0032] Example 2: Please refer to Figure 4 The automatic roller coating equipment shown has an overall structure similar to that of Embodiment 1. The transmission mechanism 13 includes a drive disc, a transmission belt, and a driven disc. The drive disc is connected to one end of the reciprocating screw 9, and the driven disc is connected to one end of the stirring rod 14. When the reciprocating screw 9 rotates through the stepper motor 5, it drives the drive disc at the bottom to rotate. Under the action of the transmission belt, the driven disc drives the stirring rod 14 to rotate. Since the diameter of the drive disc in the transmission mechanism 13 is smaller than the diameter of its driven disc, when the reciprocating screw 9 drives the drive disc to rotate rapidly, its driven disc drives the stirring rod 14 to rotate slowly, ensuring that the roller on the placement plate 3 is in a stable state.

[0033] In practical operation, this invention works as follows: The roller to be sprayed is placed on top of the placement plate 3. Then, the stepper motor 5 on the frame 2 is started. Under the action of the stepper motor 5, the reciprocating screw 9 at the output end rotates. At this time, the nozzle 6 slides up and down within the frame 2. Under the action of the transmission mechanism 13, the placement plate 3 rotates, causing the roller itself to rotate along with the placement plate 3 during the sliding of the nozzle 6. Simultaneously, the curing component 10 on one side completes a multi-layer thin-spray coating. This method saves a significant amount of manpower and resources when dealing with large rollers and improves overall spraying efficiency. Furthermore, during the spraying process, the transmission mechanism 13 drives the stirring component inside the spraying cylinder 15 to rotate. This prevents layering within the spraying cylinder 15 during spraying, improving the subsequent spraying effect.
