Description

Technical Field

[0001] This utility model relates to the field of optical conductors, specifically to an OPC edge washing device. Background Technology

[0002] An OPC drum is a photoelectric conversion device, where OPC stands for Organic Photoconductor. An OPC drum is made by coating the outer surface of a vertically placed conductive aluminum cylinder with OPC material. During the coating process, OPC material accumulates at the bottom of the drum's outer surface, resulting in a thicker layer of OPC material, which affects print quality. Therefore, it is necessary to remove this thick layer of OPC material. Currently, this is typically done manually by wiping the bottom of the drum's outer surface with a scouring pad. However, manual wiping is slow, inefficient, and can easily damage the drum. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides an OPC edge cleaning device, comprising: a clamp gripping the top of a vertically placed OPC drum; a rotary motor positioned above the clamp and driving the clamp to rotate; a cotton strip unwound from an unwinding reel, first crossing the OPC drum and abutting against the bottom edge of the outer circumference of the OPC drum, and then being wound up by a take-up reel; and a spray head near the cotton strip for spraying cleaning fluid onto the cotton strip; wherein the cotton strip unwound from the unwinding reel passes the spray head before passing the OPC drum.

[0004] Preferably, the unwinding reel is located to the left of the OPC drum, and the unwinding reel is equipped with an unwinding motor that drives it to rotate to unwind the cotton strip.

[0005] Preferably, the take-up reel is located to the right of the OPC drum, and the take-up reel is equipped with a take-up motor that drives it to rotate to take up the cotton strip.

[0006] Preferably, it also includes a pair of tension adjustment wheels located on the left and right sides of the OPC drum, which convey the cotton belt and press the cotton belt tightly onto the outer circumferential surface of the OPC drum.

[0007] Preferably, it also includes a liquid collection tank located directly below the OPC drum.

[0008] Preferably, it also includes: a storage tank connected to the spray head via a supply pipe, and a supply valve provided on the supply pipe.

[0009] Preferably, the liquid supply pipe is vertically positioned, the liquid storage tank is located at the top of the liquid supply pipe, and the spray head is located at the bottom of the liquid supply pipe.

[0010] Preferably, the spray head is located to the left of the OPC drum and directly above the collection tank.

[0011] Preferably, the liquid supply valve is a flow valve.

[0012] The advantages and beneficial effects of this utility model are as follows: It provides an OPC edge cleaning device, which can use cotton cloth strips to clean off the thicker OPC material at the bottom of the outer periphery of the vertically placed OPC drum, and can improve cleaning efficiency and improve the yield of OPC drums.

[0013] The unwind reel continuously unwinds the cotton cloth tape, and the take-up reel continuously winds it up. The cotton cloth tape unwound from the unwind reel first passes through the spray nozzle and then through the OPC drum. The spray nozzle sprays cleaning fluid onto the cotton cloth tape along the way, causing the cotton cloth tape to carry the cleaning fluid. When the cotton cloth tape carrying the cleaning fluid passes through the OPC drum, it can rub and clean the OPC material at the bottom of the outer peripheral surface of the OPC drum. Through the friction and cleaning of a section of cotton cloth tape, the thicker OPC material at the bottom of the outer peripheral surface of the OPC drum can be removed.

[0014] Since the collection tank is located directly below the OPC drum and the spray head, the excess cleaning fluid sprayed by the spray head (i.e. the cleaning fluid that is not sprayed onto the cotton cloth belt) and the cleaning fluid that falls off when rubbing and cleaning the bottom of the OPC material on the outer periphery of the OPC drum can all drip into the collection tank for subsequent waste liquid recycling.

[0015] The used cotton strips wound up on the reel can also be recycled later. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the present invention. Detailed Implementation

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] The specific technical solution of this utility model is as follows:

[0019] like Figure 1As shown, this utility model provides an OPC edge cleaning device for cleaning OPC material with a thicker bottom edge on the outer periphery of a vertically placed OPC drum 8. The device includes: a clamp 11 that grips the top of the vertically placed OPC drum 8; a rotary motor 12 positioned above the clamp 11 and driving its rotation; an unwinding reel 2 located on the left side of the OPC drum 8; and a rewinding reel 3 located on the right side of the OPC drum 8. The material is unwound from the unwinding reel 2, first passing over the OPC drum 8 and abutting against the bottom edge of the outer periphery of the OPC drum 8, and then being rewound. The cotton cloth belt 4 wound by the disc 3, a pair of tension adjustment wheels 51 and 52 respectively located on the left and right sides of the OPC drum 8 to convey the cotton cloth belt 4 and press the cotton cloth belt 4 onto the outer circumference of the OPC drum 8, a spray head 61 located on the left side of the OPC drum 8 near the cotton cloth belt 4 and used to spray cleaning fluid onto the cotton cloth belt 4, a storage tank 63 connected to the spray head 61 through a supply pipe 62, a supply valve 64 located on the supply pipe 62, and a collection tank 7 located directly below the OPC drum 8 and the spray head 61;

[0020] The unwinding reel 2 is equipped with an unwinding motor 21 that drives its rotation to unwind the cotton fabric strip 4;

[0021] The take-up reel 3 is equipped with a take-up motor 31 that drives its rotation to take up the cotton strip 4;

[0022] The liquid supply pipe 62 is vertically positioned, the liquid storage tank 63 is located at the top of the liquid supply pipe 62, and the liquid spray head 61 is located at the bottom of the liquid supply pipe 62; the liquid supply valve 64 is a flow valve.

[0023] The working principle of this OPC edge-washing device includes:

[0024] The clamp 11 grips the top of the vertical OPC drum 8 that needs to be processed (the OPC material at the bottom of the outer periphery of the OPC drum 8 is thicker), and then the cotton cloth strip 4 on the unwinding reel 2 passes over the left tension adjusting wheel 51, the bottom of the outer periphery of the OPC drum 8, and the right tension adjusting wheel 52 in sequence, and is then wound up by the take-up reel 3. At this time, a pair of tension adjusting wheels 51 and 52 press the cotton cloth strip 4 tightly on the outer periphery of the OPC drum 8, and the spray head 61 is located directly above the cotton cloth strip 4.

[0025] Then, the liquid supply valve 64 is opened and the unwinding motor 21, the winding motor 31, and the rotary motor 12 are started; the unwinding motor 21 drives the unwinding reel 2 to continuously unwind the cotton fabric strip 4, and the winding motor 31 drives the winding reel 3 to continuously wind the cotton fabric strip 4. The cotton fabric strip 4 unwound from the unwinding reel 2 first passes through the spray nozzle 61 and then through the OPC drum 8; the liquid storage tank 63 supplies cleaning fluid (the liquid storage tank 63 contains cleaning fluid for cleaning OPC materials) to the spray nozzle 61 through the liquid supply pipe 62. The spray nozzle 61 sprays the cleaning fluid onto the cotton fabric strip 4, so that the cotton fabric strip 4 carries the cleaning fluid; the rotary motor 12 drives the OPC drum 8 to rotate around the vertical axis (with... The body allows the rotation direction of the OPC drum 8 to be opposite to the conveying direction of the cotton cloth belt 4; when the cotton cloth belt 4 carrying the cleaning fluid passes through the OPC drum 8, it can rub and clean the OPC material at the bottom of the outer peripheral surface of the OPC drum 8. Through the friction cleaning of a section of the cotton cloth belt 4, the thicker OPC material at the bottom of the outer peripheral surface of the OPC drum 8 can be cleaned away; (specifically, the appropriate width of the cotton cloth belt 4 can be selected according to the vertical width of the thicker OPC material at the bottom of the outer peripheral surface of the OPC drum 8, so that the cotton cloth belt 4 can cover the vertical width of the thicker OPC material, thereby cleaning away the thicker OPC material;)

[0026] Since the collection tank 7 is located directly below the OPC drum 8 and the spray head 61, the excess cleaning fluid sprayed by the spray head 61 (i.e. the cleaning fluid that is not sprayed onto the cotton cloth belt 4) and the cleaning fluid that falls off when rubbing and cleaning the OPC material at the bottom of the outer peripheral surface of the OPC drum 8 can all drip into the collection tank 7 for subsequent waste liquid recycling.

[0027] The used cotton strip 4 wound on the winding reel 3 can also be recycled later.

[0028] As can be seen from the above, the OPC edge cleaning device of this utility model can use cotton cloth strip 4 to clean the thicker OPC material at the bottom of the outer periphery of the vertical OPC drum 8, and can improve the cleaning efficiency and improve the yield of OPC drum 8.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
