Description

Technical Field

[0001] This utility model relates to the field of carbon-coated aluminum foil production technology, specifically to a high-cleanliness carbon-coated aluminum foil printing roller surface cleaning device. Background Technology

[0002] During the production of carbon-coated aluminum foil, a large number of contaminants adhere to the surface of the printing roller. These contaminants mainly come from process residues and environmental factors, such as lubricating oil and hydraulic oil from the mechanical transmission parts of the equipment, or residues from the demolding process before coating, forming an oil film that affects the adhesion of the carbon coating layer, or incompletely cured carbon paste, conductive adhesive, or carbon slag formed by overflow at the coating edge, which accumulates in the grooves of the printing roller. If the printing roller is not cleaned in time, these contaminants will cause a decrease in the wettability of the carbon coating paste, forming defects such as pinholes and fisheyes, which will affect the coating thickness.

[0003] Referring to the patent document: Patent Publication No. CN213734136U, Patent Publication Date 2021-07-21, a printing roller surface cleaning device is disclosed. The key technical points include a box body and a box cover that are interlocked. A rotating assembly is provided inside the box body, and a cleaning assembly is connected to the lower side of the box cover. The rotating assembly includes support shafts rotatably connected to the left and right inner walls of the box body. Adjustment shafts are slidably positioned and connected to opposite sides of the two support shafts. The opposite sides of the two adjustment shafts are fixed to a three-jaw chuck. A rotary motor is connected to the right end of the right support shaft, and the motor body is fixed to the box body. The cleaning assembly includes multiple nozzles connected to the lower side of the box body. The nozzles are connected to a water guide component inside the box body, and a water inlet pipe is connected to the water guide component. The water inlet pipe extends upwards through the box body, and a drain pipe is connected to the bottom of one side of the box body. This device allows the printing roller to rotate during cleaning, resulting in a more thorough cleaning and less residue buildup.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] As a transfer tool in the production of carbon-coated aluminum foil, printing rollers accumulate carbon powder residue, oil stains, and micron-sized particulate contaminants on their surface during long-term use. Traditional cleaning methods mainly involve manual wiping or soaking and rinsing. However, manual wiping is only suitable for situations with a small amount of surface contaminants and is not suitable for cleaning large quantities of printing rollers. Existing equipment for soaking and rinsing is mostly separate and does not integrate the two processes. This requires transferring the printing rollers to a spray station for further cleaning after soaking, resulting in a large workload, slow efficiency, and a risk of cross-contamination during the transfer process.

[0006] Therefore, this utility model provides a high-cleanliness carbon-coated aluminum foil surface cleaning device for printing rollers. Utility Model Content

[0007] To address the problems of traditional printing roller cleaning methods, such as manual scrubbing being unsuitable for large-scale printing roller cleaning, and the separation of soaking and spraying processes leading to cross-contamination and low efficiency, the purpose of this utility model is to provide a high-cleanliness printing roller surface cleaning device using carbon-coated aluminum foil.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-cleanliness printing roller surface cleaning device for carbon-coated aluminum foil, comprising a cleaning box, wherein the upper part of the cleaning box is provided with a cleaning mechanism for cleaning the surface of the printing roller coated with carbon-coated aluminum foil, the cleaning mechanism comprising:

[0009] The conveying assembly includes two slide rails fixedly installed at the bottom of the cleaning box. A slider is slidably mounted on one side of each slide rail. A screw is provided in the middle of each slide rail. The middle of each slider is threaded onto the upper part of the screw. A moving rail is slidably passed through one side of each slider. A moving block is fixedly installed at the top of each moving rail. Hooks can be detachably installed on opposite sides of each moving block. Two symmetrically distributed drive slots are opened at the top of the cleaning box. The middle of each moving block is slidably mounted inside the drive slot. A drive assembly is provided on one side of one of the screws.

[0010] The cleaning assembly, located in the middle of the cleaning box, is used to soak and rinse the printing rollers.

[0011] Preferably, the cleaning assembly includes a fixed cover fixedly installed on the upper part of the cleaning box, a set of spray pipes fixedly installed at corresponding positions of the fixed cover and the cleaning box, and a set of ultrasonic plates fixedly installed on the lower inner surface of the cleaning box.

[0012] Preferably, the drive assembly includes a servo motor fixedly mounted on one side of the cleaning box, one end of one screw fixedly mounted on the drive end of the servo motor, and the two screws are connected by a transmission belt.

[0013] Preferably, each of the two slide rails has a groove in the middle, both screws are rotatably installed in the middle of the groove, and both sliders are slidably locked inside the groove.

[0014] Preferably, both hooks are connected to each other via a locking block and a moving block, and the inner groove surfaces of both hooks are covered with a medical-grade silicone anti-slip pad.

[0015] Preferably, a drain pipe is fixedly installed on one side of the lower part of the cleaning box, and two symmetrically distributed baffles are fixedly installed on the upper part of the cleaning box.

[0016] Beneficial effects

[0017] This invention provides a high-cleanliness cleaning device for the surface of printing rollers coated with carbon aluminum foil. Compared with the prior art, it has the following advantages:

[0018] 1. When the screw is driven to rotate by the servo motor, the moving block moves from the horizontal to the inclined section along the drive groove, driving the printing roller to be immersed in the cleaning solution at a uniform speed to complete the soaking and cleaning. Then, it rises along the other inclined section to the horizontal section on the unloading side to receive spray rinsing. Thus, the printing roller completes the dual processes of softening and peeling off oil stains and rinsing off residual impurities in a single transmission process, avoiding the time loss of manual intervention and improving the cleaning efficiency of the printing roller.

[0019] 2. This application can generate a high-frequency cavitation effect when the printing roller is immersed in the cleaning solution using an ultrasonic plate. The instantaneous high pressure of the bursting bubbles breaks and peels off the micron-sized oil particles on the surface of the printing roller. At the same time, the impurities and residual cleaning solution on the printing roller are cleaned by the spray pipe. With the help of the fixed cover, the water mist is guided and collected to avoid the cleaning solution splashing and polluting the surrounding environment. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4This utility model provides a technical solution: a high-cleanliness printing roller surface cleaning device for carbon-coated aluminum foil, including a cleaning box 1, and a cleaning mechanism 2 provided on the upper part of the cleaning box 1 for cleaning the surface of the printing roller coated with carbon-coated aluminum foil. The cleaning mechanism 2 includes:

[0027] The conveying assembly 21 includes two slide rails 211 fixedly installed at the lower part of the cleaning box 1. A slider 213 is slidably mounted on one side of each slide rail 211. A screw 212 is provided in the middle of each slide rail 211. The middle of each slider 213 is threaded onto the upper part of the screw 212. A movable rail 214 slidably passes through one side of each slider 213. A movable block 217 is fixedly installed at the top of each movable rail 214. Rotation of the screw 217 on the movable rail 214 drives the slider 213 to move along the slide rail 211, thus moving the movable rail 214 and... The moving blocks 217 move synchronously. Hooks 218 can be detachably installed on opposite sides of the two moving blocks 217. Two symmetrically distributed drive slots 216 are opened on the upper part of the cleaning box 1. The middle of the two moving blocks 217 are slidably locked inside the drive slots 216. The drive slots 216 are zigzag-shaped, and the upper two ends and the middle are horizontal track slots. The track slots connecting the two ends and the middle are inclined. The angle between the inclined section and the horizontal section is 30°. The shorter section of the upper horizontal track slot is the feeding side. A drive assembly is provided on one side of one of the screws 212.

[0028] The cleaning component 22 is located in the middle of the cleaning box 1 and is used to soak and rinse the printing roller.

[0029] The cleaning assembly 22 includes a fixed cover 221 fixedly installed on the upper part of the cleaning box 1. The fixed cover 221 is made of stainless steel 304 and can be used to spray water mist from the spray pipe 222 located at the lower part of the cleaning box 1 to the upper part. A set of spray pipes 222 are fixedly installed at the corresponding positions of the fixed cover 221 and the cleaning box 1. A set of ultrasonic plates 223 are fixedly installed on the lower inner surface of the cleaning box 1. The ultrasonic plates 223 have a power of 500W and a working frequency of 40kHz and are evenly distributed at the bottom of the cleaning box.

[0030] The drive assembly includes a servo motor 215 fixedly mounted on one side of the cleaning box 1. One end of a screw 212 is fixedly mounted on the drive end of the servo motor 215. The two screws 212 are connected by a transmission belt. The servo motor 215 is a three-phase AC synchronous motor of model 1FT7105-5AC71-1NA4. Driven by the servo motor 215, one screw 212 can be rotated. Driven by the transmission belt, both screws 212 can be rotated. A tension adjustment mechanism is provided in the middle of the transmission belt.

[0031] Both slide rails 211 have a groove 2121 in the middle. Both screws 212 are rotatably installed in the middle of the groove 2121. Both sliders 213 are slidably locked inside the groove 2121. Both ends of the screws 212 are installed in the middle of the groove 2121 through deep groove ball bearings. At the same time, the groove 2121 can limit the sliders 213, so that they can move stably along the slide rail 211.

[0032] Both hooks 218 are connected to each other via locking blocks and moving blocks 217. The inner groove surfaces of both hooks 218 are covered with medical silicone anti-slip pads. The locking blocks are spring-loaded, allowing for quick replacement of the hooks 218 to accommodate rollers of different diameters.

[0033] A drain pipe 11 is fixedly installed on one side of the lower part of the cleaning box 1. Two symmetrically distributed baffles 219 are fixedly installed on the upper part of the cleaning box 1. The drain pipe 11 has a diameter of 50mm and is used to drain the liquid in the cleaning box 1. The baffles 219 are used to assist the operator in disassembling and installing the printing roller and to prevent the printing roller from falling into the cleaning box 1.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, when cleaning the printing roller, both ends of the roller are placed on hooks 218. The servo motor 215 drives the screw 212 to rotate, causing the slider 213 to move along the slide rail 211. This causes the moving rail 214 and the moving block 217 to move synchronously. Since the moving block 217 is engaged in its drive groove 216, it moves along the drive groove 216 during operation, allowing it to move downwards through the inclined track groove until it reaches the middle horizontal section. At this point, the printing roller is at its lowest point. The cleaning tank 1 contains printing roller cleaning fluid, ensuring the roller is completely immersed in the cleaning fluid after reaching the lowest point. Then, the ultrasonic plate 223 is activated. Ultrasonic vibration cleans oil stains and other impurities on the printing roller. Under the continuous conveying of the screw 212, the moving block 217 moves along the drive groove 216 to the inclined track groove on the other side. Under the limit of the moving rail 214, it moves obliquely upward until it reaches the straight section. At this time, it can be connected to the spray pipe 222 through the external conveying pipe to spray clean water to clean the printing roller until the printing roller leaves the bottom of the fixed cover 221, at which point the spraying operation stops, thus completing the cleaning task. The operator can then unload it. At this time, the reverse drive of the servo motor 215 resets the hook 218, which moves to the other side of the cleaning box 1. This cycle is repeated to clean the printing roller.
