Description

Technical Field

[0001] The present invention relates to the technical field of aluminum tube cleaning, and particularly relates to a precision aluminum tube cleaning device for a photosensitive drum. Background Art

[0002] The precision aluminum tube used in a photosensitive drum is a core component of the photosensitive drum in printers and copiers, and is usually referred to as the "photosensitive drum cylinder" or "photosensitive drum aluminum tube". As a substrate, it bears the photosensitive material coating and generates charge image signals through photoelectric conversion. During the processing, the aluminum tube needs to be cleaned to ensure that the surface is dust-free, free of oil stains and oxides, so as to meet the requirements of subsequent coating or coating processes.

[0003] A patent document with the publication number CN202860934U discloses an aluminum tube cleaning device, which includes a water tank. An inlet pipe is provided above the water tank. Multiple horizontal support rods are respectively and fixedly installed at the bottom of the water tank. Multiple vertical support rods are respectively fixed between the multiple horizontal support rods. The multiple horizontal support rods and vertical support rods form a grid-shaped support. There is a gap between the multiple horizontal support rods and vertical support rods and the bottom surface of the water tank. Multiple air pipes are respectively and fixedly installed at the bottom of the water tank. The multiple air pipes respectively pass through below the multiple horizontal support rods and vertical support rods, and multiple air holes are respectively provided on the pipe walls of each air pipe. The multiple horizontal support rods and vertical support rods installed at the bottom of the water tank form a grid-shaped support, and the air pipes pass through below it to generate bubbles, and the aluminum tube is assisted to be cleaned through the bubbles.

[0004] The above-mentioned prior art uses the air bubbles generated by the air pipes during cleaning to assist in cleaning, and its principle is similar to that of an ultrasonic bubbler. The bubbler drives the bubbling tube to eject high-pressure bubbles through compressed air, and combines with the ultrasonic cavitation effect to jointly generate shock waves, which can peel off the oil stains, oxide layers and particulate matters on the surface of the aluminum tube. Therefore, the ultrasonic bubbler can be used for aluminum tube cleaning, especially suitable for removing pollutants such as grease and polishing residues on the surface and inside of precision aluminum tubes.

[0005] However, there are still the following problems in this solution. Both the prior art and the ultrasonic bubbler use bubbles to assist in cleaning the aluminum tube. After the bubbles are generated, they will move upward, but during the process, the bubbles cannot fully contact the side surface of the aluminum tube. Especially for the inside of the aluminum tube, because the port of the aluminum tube is small, only a small amount of bubbles can enter, which affects the cleaning effect of the aluminum tube. Summary of the Invention

[0006] The present invention provides a precision aluminum tube cleaning device for a photosensitive drum, aiming to solve the problem that when the bubbles rise, they cannot fully contact the side surface of the aluminum tube, and the number of bubbles entering the inside of the aluminum tube is small, which affects the cleaning effect of the aluminum tube in the related art.

[0007] The precision aluminum tube cleaning device for a photosensitive drum of the present invention includes a cleaning pool and a placement frame for placing the tube body. A rotating assembly, a driving assembly, and a limiting assembly are provided on the placement frame.

[0008] The rotating assembly includes: a first collar rotatably assembled on the placement frame, and a second collar rotatably assembled within the first collar. The axis of the first collar is arranged horizontally, and the axis of the second collar is arranged perpendicular to the axis of the first collar.

[0009] The driving assembly is connected to the first collar and the second collar to drive them to rotate respectively.

[0010] The second collar is slidably sleeved outside the tube body, and the limiting assembly is arranged on the second collar to cooperate with the tube body to fix the tube body within the second collar.

[0011] An air pipe is provided at the bottom of the cleaning pool. The air pipe is located at the bottom of the tube body, and air holes corresponding to the center of the first collar are opened on the air pipe.

[0012] Air bubbles are ejected upward from the air holes. When the second collar is fixed at both ends of the tube body, the second collar and the first collar rotate reciprocally simultaneously. If the second collar is located at the upper end of the tube body, the lower end of the tube body rotates, and the air bubbles contact the side surface of the tube body; if the second collar is located at the lower end of the tube body, the upper end of the tube body rotates, and the air bubbles enter the interior of the tube body and contact its inner wall.

[0013] The effect is that when placing the tube body, insert the tube body into the second collar, then place the upper end of the tube body within the second collar, and then fix the tube body within the second collar through the limiting assembly. Then, the driving assembly drives the first collar and the second collar to rotate synchronously. The first collar and the second collar rotate reciprocally in different directions, thereby driving the lower end of the tube body to rotate, and the tube body is in an inclined state during rotation. At the same time, the gas in the air pipe is ejected through the air holes to form air bubbles. The air bubbles rise in the cleaning liquid. When the air bubbles rise, they contact the inclined and rotating tube body, enabling the tube body to be in full contact with the air bubbles. At this time, the outer side of the tube body is cleaned. Then, move the tube body so that the second collar cooperates with the lower end of the tube body. The driving assembly drives the tube body to rotate again. At this time, the tube body is also in an inclined state, and the lower end of the tube body corresponds to the air holes. The air bubbles enter the tube body. As the tube body rotates, the contact area between the air bubbles and the inner wall of the tube body is increased. By the second collar cooperating with the upper and lower ends of the tube body respectively, the cleaning of the outer side and the inner wall of the tube body is improved, and the cleaning effect of the tube body is enhanced.

[0014] Preferably, the driving assembly includes: a first pusher, a first push rod, and a first gear. The first pusher is arranged on the placement frame. The first push rod is slidably assembled on the placement frame. The output end of the first pusher is connected to the first push rod. The first gear is coaxially connected to the rotating shaft of the first collar. A first tooth groove meshing with the first gear is opened on the first push rod.

[0015] The effect is that the push piece drives the push rod to move back and forth, the push rod drives the gear to rotate through the tooth groove, and the rotation of the gear drives the sleeve ring to rotate back and forth.

[0016] Preferably, a mounting rod is provided on the placement frame, and the driving assembly also includes: a push piece 2, a push rod 2, and a gear 2. The push piece 2 is provided on the mounting rod, the push rod 2 is slidably assembled on the mounting rod, the gear 2 is coaxially connected to the rotating shaft of the ring 2, and the push rod 2 is provided with a tooth groove 2 that meshes with the gear 2.

[0017] The effect is that push piece 2 drives push rod 2 to move back and forth, push rod 2 drives gear 2 to rotate through tooth groove 2, the rotation of gear 2 drives sleeve ring 2 to rotate back and forth, and then drives sleeve ring 2 to rotate back and forth in sleeve ring 1, so as to drive the end of the tube body to make a circular motion.

[0018] Preferably, the mounting rod is connected to the side of the first sleeve ring, a mounting plate is provided on the placement frame, the end of the mounting rod cooperates with the mounting plate, and the mounting rod is rotatably arranged around the rotating shaft of the first sleeve ring on the mounting plate.

[0019] The effect is that the mounting rod is rotatably assembled on the mounting plate, and when the collar rotates, the mounting rod rotates on the mounting plate with the collar, that is, the push piece 2, the push rod 2 and the tooth groove 2 are all driven to rotate with the collar, so that when the collar rotates, the push piece 2, the push rod 2 and the tooth groove 2 are in a stationary state relative to the collar, so that when the collar rotates, the push piece 2 drives the collar 2 to rotate inside the collar.

[0020] Preferably, the limit assembly includes: a push piece three, a push rod three, a push rod, a sleeve, and an elastic piece. The push piece three is arranged on the mounting rod. The push rod three is slidably assembled on the mounting rod. The output end of the push piece three is connected to the push rod three. The push rod is slidably arranged on the mounting rod toward the direction of the tube body. The sleeve is arranged on the side of the push rod close to the tube body. The elastic piece is connected to the push rod and the mounting rod. The elastic piece is used to drive the push rod away from the tube body. A top inclined surface is provided on the push rod three, and the top inclined surface cooperates with an end of the push rod away from the tube body. The push rod three moves through the top inclined surface to drive the push rod to move close to the tube body, so that the sleeve abuts against the tube body to fix the tube body in the ring two.

[0021] The effect is that the push piece three drives the push rod three to move, and the movement of the push rod three drives the top inclined surface to cooperate with the push rod, drives the push rod and the ferrule to move close to the tube body, and after the ferrule abuts against the tube body, the tube body is fixed in the ring two.

[0022] Preferably, an intermediate frame is provided at the bottom of the cleaning tank, and the intermediate frame is located between the air pipe and the tube body. A frame is provided outside the cleaning tank, and a hoisting assembly is provided on the frame. The hoisting assembly is connected to the placement frame to drive the placement frame to move up and down in the cleaning tank. After the limiting assembly releases the restriction on the upper end of the tube body, the intermediate frame supports the lower end of the tube body, and the second ring moves to the bottom of the tube body with the placement frame.

[0023] The effect is that after the outer side of the pipe body is cleaned, the hoisting assembly drives the placing frame to move downward. After the lower end of the pipe body abuts against the middle frame, the movement stops, and the pipe body is supported by the middle frame. Then, the limiting assembly releases the restriction on the upper end of the pipe body, and the placing frame is moved downward to drive the second collar to move to the bottom of the pipe body. Then, the lower end of the pipe body is fixed by the limiting assembly to achieve the fixation of the lower end of the pipe body.

[0024] Preferably, the middle frame includes a fixed frame and a movable frame. The fixed frame is fixedly connected to the cleaning pool. The movable frame slides in the fixed frame along the diagonal direction of the fixed frame. The movable frame includes a plurality of rod bodies that intersect and are vertically arranged. A fourth pusher is provided on the fixed frame, and the output end of the fourth pusher is connected to the movable frame. After the second collar moves to the lower end of the pipe body, the fourth pusher drives the movable frame to move, so that the gap between the rod bodies corresponds to the lower end of the pipe body, and the support for the pipe body is released.

[0025] The effect is that after the second collar is fixed to the lower end of the pipe body, the fourth pusher drives the movable frame to move along the diagonal direction of the fixed frame, so that the gap of the movable frame moves to correspond to the pipe body. At this time, the support for the pipe body is removed, and the phenomenon that the movable frame interferes with the rotation of the pipe body is reduced.

[0026] Preferably, multiple groups of the first collars are arranged along the length direction of the first push rod. Each group consists of multiple first collars arranged perpendicular to the first push rod. The rotating shafts of two adjacent first collars in each group are connected to each other. A first gear and a first tooth groove are respectively provided with multiple ones corresponding to multiple groups of the first collars. When the first push rod moves, it drives multiple groups of the first collars to rotate synchronously.

[0027] The effect is that the first pusher drives the first push rod to move, and at the same time drives multiple groups of the first collars to rotate, thereby driving multiple pipe bodies to rotate along with the first collars.

[0028] Preferably, multiple mounting rods are provided corresponding to multiple groups of the first collars. The mounting rods are arranged along the arrangement direction of multiple first collars in each group. A second tooth groove and a second gear are respectively provided with multiple ones corresponding to multiple first collars, and the second gears are respectively connected to the corresponding second collars. When the second push rod moves, it drives multiple second collars to rotate synchronously through the second tooth groove.

[0029] The effect is that the second pusher drives the second push rod to move. The second push rod drives multiple second collars to rotate simultaneously through the second tooth groove and the second gear, and cooperates with the first collar, thereby driving multiple pipe bodies to rotate simultaneously.

[0030] Preferably, an extension part is provided on the second collar. The extension part extends to the outside of the first collar, and a relief groove is formed on the extension part. The clamping sleeve is arranged in the relief groove to cooperate with the pipe body.

[0031] The effect is that the clamping sleeve cooperates with the pipe body through the relief groove, and the phenomenon that the first collar interferes with the movement of the clamping sleeve is reduced.

[0032] Beneficial effects:

[0033] The present invention provides a first collar and a second collar, and the second collar is sleeved on the upper and lower ends of the pipe body respectively. When the second collar is engaged with the upper end of the pipe body, the reciprocating rotation of the first collar and the second collar drives the lower end of the pipe body to rotate. When the second collar is engaged with the lower end of the pipe body, the reciprocating rotation of the first collar and the second collar drives the upper end of the pipe body to rotate. At the same time, the pipe body is in an inclined state during rotation, so that the bubbles can fully contact the inner and outer sides of the pipe body. And when the upper end of the pipe body rotates, the lower end of the pipe body corresponds to the air holes, so that the bubbles can directly enter the pipe body, and the rotation of the pipe body enables the bubbles to fully contact the inner wall of the pipe body, thereby improving the cleaning effect on the pipe body.

The first gear 43 and the tooth groove 421 are correspondingly provided with multiple ones corresponding to the multiple groups of first collars 31, that is, the first push rod 42 is simultaneously engaged with multiple first gears 43. A pipe body 01 is placed in each first collar 31. When the first pusher 41 drives the first push rod 42 to move, the multiple groups of first collars 31 are synchronously driven to rotate through the multiple tooth grooves 421 and the first gears 43, and then multiple pipe bodies 01 are simultaneously driven to rotate with the first collars 31.

[0067] Refer to Figure 3 , Figure 4 , Figure 10, there are multiple sets of mounting rods 7 corresponding to multiple sets of first sleeves 31, and the mounting rods 7 are arranged along the arrangement direction of multiple first sleeves 31 in each set. A second sleeve 32 is arranged in each first sleeve 31. There are multiple second tooth grooves 451 and second gears 46 corresponding to the multiple first sleeves 31. The multiple second gears 46 are connected to the corresponding second sleeves 32. When the second pusher 44 drives the second push rod 45 to move, it further drives the multiple second sleeves 32 to rotate. At the same time, under the action of the first sleeve 31, the tube body 01 is driven to rotate simultaneously, so as to realize the simultaneous cleaning of multiple tube bodies 01.

[0068] Refer to Figure 2 , Figure 8 , an intermediate frame 8 is arranged at the bottom of the cleaning tank 21. The intermediate frame 8 is arranged above the air pipe 23 and below the tube body 01, that is, the intermediate frame 8 is located between the air pipe 23 and the tube body 01.

[0069] When the second sleeve 32 cooperates with the upper end of the tube body 01, the lower end of the tube body 01 is arranged at an interval from the intermediate frame 8, reducing the phenomenon that the intermediate frame 8 interferes with the rotation of the lower end of the tube body 01. When the second sleeve 32 needs to cooperate with the lower end of the tube body 01, the first sleeve 31 and the second sleeve 32 stop rotating, so that the tube body 01 is in a vertical state. Then the hoisting assembly 6 drives the placement frame 22 to move downward, so that the lower end of the tube body 01 moves to the position of the intermediate frame 8, and the intermediate frame 8 supports the tube body 01. At this time, the clamping sleeve 54 is separated from the tube body 01. Although the clamping sleeve 54 is separated from the tube body 01, the tube body 01 is still located in the second sleeve 32. Then the hoisting assembly 6 drives the placement frame 22 to move downward, and the second sleeve 32 moves with the placement frame 22 until the second sleeve 32 moves to the bottom of the tube body 01. Then the clamping sleeve 54 is moved again to fix the tube body 01, so that the second sleeve 32 is fixed at the lower end of the tube body 01.

[0070] Refer to Figure 8 , the intermediate frame 8 includes a fixed frame 81 and a movable frame 82. The fixed frame 81 is fixedly connected to the cleaning tank 21. The movable frame 82 is slidably assembled on the fixed frame 81, and the movable frame 82 is slidably arranged on the fixed frame 81 along the diagonal direction of the fixed frame 81. The movable frame 82 includes multiple rod bodies 821, and the multiple rod bodies 821 intersect and are perpendicularly arranged. A fourth pusher 9 is arranged on the fixed frame 81. The fourth pusher 9 is set as a cylinder, and the output end of the fourth pusher 9 is connected to the movable frame 82.

[0071] Initially, the intersection of the rod body 821 corresponds to the lower end of the pipe body 01 to support the bottom of the pipe body 01. After the second collar 32 is fitted with the bottom of the pipe body 01, the fourth pusher 9 drives the movable frame 82 to move diagonally along the fixed frame 81, so that the gap between the rod bodies 821 corresponds to the lower end of the pipe body 01, releasing the support for the pipe body 01. At the same time, it is convenient for the first collar 31 and the second collar 32 to drive the pipe body 01 to rotate, so as to reduce the phenomenon that the movable frame 82 interferes with the rotation of the pipe body 01. In addition, when the first collar 31 clamps the upper end of the pipe body 01, the intersection of the rod bodies 821 corresponds to the lower end of the pipe body 01, and the intersection point of the rod bodies 821 corresponds to the air hole 231, so that the ejected bubbles rise through the intersection. When the bubbles pass through the intersection of the rod bodies 821, the bubbles disperse to form several small bubbles, further increasing the contact area between the bubbles and the pipe body 01.

[0072] Refer to Figure 2 、 Figure 11 As shown in FIGS. 6 and 7, the hoisting assembly 6 includes: a slide rail 61, a sliding frame 62, a power member 63, and a suspension rod 64. The slide rail 61 is arranged on the top of the frame 1. The sliding frame 62 is slidably assembled on the slide rail 61. The power member 63 is set as a cylinder, and the output end of the cylinder is connected to the suspension rod 64. The suspension rod 64 is arranged in the vertical direction. A lifting ring 222 is arranged on the side surface of the placement frame 22, and a hook is arranged at the lower end of the suspension rod 64. The hook cooperates with the lifting ring 222 to hoist the placement frame 22, and the placement frame 22 can be driven to move up and down by the power member 63.

[0073] Refer to Figure 2 In addition, a plurality of cleaning pools 21 are arranged in an array to clean the pipe body 01 in multiple processes. The sliding frame 62 moves on the slide rail 61, driving the placement frame 22 to move to each cleaning pool 21 in turn to clean the pipe body 01. In addition, the slide rail 61 is arranged in a closed loop, so that the sliding frame 62 can drive the placement frame 22 to reciprocate between a plurality of cleaning pools 21, so as to remove the cleaned pipe body 01 and replace it with a new pipe body 01 for cleaning.

[0074] The implementation principle of the present invention is as follows: The first collar 31 and the second collar 32 are provided. The first collar 31 rotates on the placement frame 22, and the second collar 32 is rotatably assembled in the first collar 31. The pipe body 01 is located in the second collar 32, and then the pipe body 01 is fixed in the second collar 32 by the clamping sleeve 54 cooperating with the side surface of the pipe body 01;

[0075] In the initial state, the ferrule 54 abuts against the upper side surface of the pipe body 01 to fit the second collar 32 with the upper end of the pipe body 01. Then the first collar 31 and the second collar 32 rotate, mainly for cleaning the outer side of the pipe body 01. After the outer side is cleaned, the pipe body 01 stops rotating, and the placement frame 22 moves downward, so that the lower end of the pipe body 01 is placed on the movable frame 82. Then the ferrule 54 moves away from the pipe body 01. The placement frame 22 continues to move, driving the second collar 32 to move to the lower end of the pipe body 01. Then the ferrule 54 moves again to abut against the side surface of the pipe body 01, fixing the second collar 32 at the lower end of the pipe body 01. At this time, the inner wall of the pipe body 01 is mainly cleaned.

[0076] When the upper or lower end of the pipe body 01 rotates, the pipe body 01 is in an inclined state while rotating.

[0077] When the second collar 32 is fitted with the upper end of the pipe body 01, the first collar 31 and the second collar 32 rotate synchronously and reciprocally, driving the lower end of the pipe body 01 to rotate around the air hole 231, so that when the bubbles rise, they can fully contact the side surface of the pipe body 01. When the second collar 32 is fitted with the lower end of the pipe body 01, the lower end of the pipe body 01 approaches the air hole 231 and is aligned with the air hole 231. The bubbles ejected through the air hole 231 enter the pipe body 01 through the bottom of the pipe body 01. At this time, the first collar 31 and the second collar 32 rotate reciprocally, driving the upper end of the pipe body 01 to rotate. After the bubbles enter the pipe body 01, the pipe body 01 rotates, enabling the bubbles to contact all parts of the inner wall of the pipe body 01, improving the cleaning effect on the inside of the pipe body 01.

[0078] In addition, no matter whether the upper or lower end of the pipe body 01 rotates, its end rotates in the horizontal plane, making the contact between the bubbles and all parts of the pipe body 01 more uniform.

[0079] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
