Technical Field

[0001] This utility model relates to the field of rubber blanket cleaning technology, specifically to a rubber blanket cleaning device. Background Technology

[0002] The blanket is a core component of printing equipment such as offset printing machines and flexographic printing machines. Its surface cleanliness directly affects the printing quality. During use, ink, paper dust, dampening solution crystals and other contaminants will remain on the surface of the blanket, which needs to be cleaned.

[0003] A Chinese patent application with application number 202423160772.X discloses a rubber blanket cleaning device, comprising: a housing, a drive assembly for rotating the rubber blanket, and a limiting assembly for defining the cleaning position of the rubber blanket. The limiting assembly includes a mounting plate, a second motor fixedly mounted on the mounting plate, a mounting block fixedly mounted on the side of the second motor, a bidirectional screw fixedly mounted on the output end of the second motor, a drive block threadedly connected to the bidirectional screw, a clamping plate fixedly mounted on the bottom of the drive block, and a cleaner for cleaning the surface of the rubber blanket. This utility model provides a rubber blanket cleaning device that uses the second motor to drive the bidirectional screw to rotate, thereby causing the drive block and clamping plate to move relatively away from or closer to each other. The clamping plate holds and fixes the rubber blanket, keeping its position centered and facilitating the even spraying of cleaning fluid onto the rubber blanket.

[0004] However, the above-mentioned device can only clean one side of the rubber blanket in one cleaning process, resulting in low cleaning efficiency.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a cleaning device for rubber blankets that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: A rubber blanket cleaning device includes a cleaning frame, a conveying mechanism disposed within the cleaning frame, and a spraying mechanism for cleaning the rubber blanket.

[0008] Furthermore, the diversion pipe is connected to a return pump, which is connected to the liquid outlet of the cleaning frame via the return pipe.

[0009] Furthermore, a filter box is provided on the return pipe, and a filter element is installed inside the filter box.

[0010] Furthermore, the filter element is configured as a double layer, with the first layer being a nylon filter element and the second layer being a polytetrafluoroethylene filter element.

[0011] Furthermore, a guide groove is fixedly installed on the cleaning frame, and a moving block is slidably connected inside the guide groove, with a brush fixedly connected to the moving block.

[0012] Furthermore, a guide rod is fixedly installed at one end of the guide groove, and an elastic element is sleeved on the guide rod, with one end of the moving block in sliding contact with the guide rod.

[0013] Furthermore, a groove is provided at one end of the moving block, the depth of which gradually decreases, and the groove slides in contact with the push block. The push block is connected to the conveying mechanism through a connecting plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention relates to a rubber blanket cleaning device. During the cleaning process, the conveying mechanism drives the rubber blanket to move within the cleaning frame.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0019] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0020] like Figures 1 to 5 As shown, the rubber blanket cleaning device of this utility model includes: a cleaning frame 100, a conveying mechanism 200, and a spraying mechanism 300; the spraying mechanism 300 is used to spray cleaning liquid to clean the rubber blanket, the conveying mechanism 200 is used to drive the conveyor belt to move, and the cleaning frame 100 is used to collect the cleaning liquid. That is to say, the conveying mechanism 200 drives the rubber blanket to move within the cleaning frame 100, and the spraying mechanism 300 sprays cleaning liquid to clean the rubber blanket during its movement.

[0021] The cleaning frame 100 includes an lifting section 101 and a liquid collection section 102. The rubber blanket first enters the cleaning frame 100 from the feeding section, and then enters the liquid collection section 102 for cleaning under the drive of the conveying mechanism 200. After cleaning, the rubber blanket continues to move forward and then enters the lifting section 101 for water spraying. A movable fan can also be installed in the lifting section 101 for preliminary air drying of the rubber blanket, which can effectively reduce the subsequent drying time and improve efficiency. This is existing technology and will not be described in detail here.

[0022] Meanwhile, a liquid outlet is provided on the liquid collection section 102. The liquid collection section 102 is used to collect the cleaning liquid sprayed by the spraying mechanism 300. The bottom of the liquid collection section 102 has a certain inclination, which makes it easy for the cleaning liquid to converge to a lower position.

[0023] The conveying mechanism 200 is disposed inside the cleaning frame 100 and is used to move the rubber cloth for cleaning and lifting. Specifically, it includes a conveying motor 201 fixedly installed on the side wall of the cleaning frame 100, several transmission shafts rotatably connected to the side wall of the cleaning frame 100, transmission gears fixedly installed on the conveying shafts, a chain 202 meshing with the gears, and a conveying rod 203 fixedly connected to the chain 202.

[0024] The conveying motor 201 is fixedly connected to one of the drive shafts via a coupling. By driving the drive shaft, the transmission gear rotates, thereby moving the chain 202 and the conveying rod 203 to convey the rubber blanket. Since the rubber blanket is relatively heavy, chain drive can effectively ensure the stability and reliability of the conveying process.

[0025] It should be noted that several guide gears are also provided on the side wall of the cleaning frame 100. The guide gears are meshed with the chain 202. The guide gears ensure that the chain 202 maintains a stable trajectory during movement and avoids deviation.

[0026] However, traditional cleaning devices can only clean one side of the rubber blanket in one cleaning process, resulting in low cleaning efficiency. Therefore, the spraying mechanism 300 in this application adopts double-sided spraying, that is, it can spray cleaning liquid on both sides of the rubber blanket at the same time in one cleaning process, which can effectively improve the cleaning efficiency.

[0027] Specifically, the spraying mechanism 300 includes a lower spraying component and an upper spraying component; the upper spraying component is located above the rubber blanket, and the lower spraying component is located below the rubber blanket; during the cleaning process, the conveying mechanism 200 drives the rubber blanket to move within the cleaning frame 100, and the upper and lower spraying components work simultaneously to spray cleaning liquid onto the upper and lower surfaces of the rubber blanket respectively, achieving simultaneous cleaning of both sides, which greatly improves the cleaning effect and cleaning efficiency.

[0028] The lower spray assembly includes a spray pipe 301 and nozzles. The spray pipe 301 is fixedly connected to the side wall of the cleaning frame 100, and the nozzles are fixedly installed on the spray pipe 301. The liquid inlet end of the spray pipe 301 is connected to a cleaning liquid delivery pipe through a pump body 303, and the spray pipe 301 is arranged in a mesh pattern. The nozzles are evenly distributed on the spray pipe 301. After the cleaning liquid enters from the spray pipe 301, it is sprayed onto the rubber blanket through the nozzles, thereby cleaning the lower surface of the rubber blanket in all directions.

[0029] The upper spray assembly includes a diversion pipe 304, several branch pipes 305 fixedly connected to the diversion pipe 304, and nozzles 306 fixedly installed on the branch pipes 305. The diversion pipe 304 is fixedly connected to the cleaning frame 100 and is connected to an inlet pipe 307. Several branch pipes 305 are arranged parallel to the traveling direction of the rubber blanket, and several nozzles 306 are installed on each branch pipe 305. After entering from the diversion pipe 304, the cleaning liquid is distributed to each branch pipe 305, and then sprayed onto the rubber blanket through the nozzles 306 to clean the upper surface of the rubber blanket.

[0030] In another embodiment, the inlet pipe 307 is connected to a return pump 308, which is connected to the outlet of the cleaning frame 100 via a return pipe 309. The cleaning liquid sprayed by the lower spray assembly drips into the cleaning frame 100 and collects, and is then transported to the upper spray assembly for recycling under the action of the return pump 308. This realizes the recycling of the cleaning liquid during the cleaning process, effectively reducing the waste of cleaning liquid and improving the utilization rate of cleaning liquid.

[0031] However, the reflux liquid contains impurities washed off the rubber blanket. During the reflux process, the reflux liquid needs to be filtered to prevent blockage. Therefore, a filter box 310 is installed on the reflux pipe 309. The filter box 310 contains a filter element, which can filter the reflux liquid before it enters the reflux pump 308.

[0032] It should be added that the filter element is set as a double-layer filter element, which has a better filtration effect. The first layer is a nylon filter element, which can remove ink residue or fiber impurities with a diameter of 10-30μm in the reflux liquid; the second layer can be a polytetrafluoroethylene filter element, which can remove tiny particles with a diameter of 5-10μm. After two filtrations, impurities in the reflux liquid can be effectively removed.

[0033] It should also be noted that the filter element and the filter box 310 are connected by a sliding connection, specifically a drawer type, which makes it convenient to take out the filter element for cleaning or replacement. This is existing technology and will not be described in detail here.

[0034] In another embodiment, a brush is also provided, which is arranged along the width of the rubber blanket. The brush can scrub the rubber blanket during the cleaning process, resulting in better cleaning. Several brushes are arranged parallel to the direction of movement of the rubber blanket, so that the rubber blanket can be repeatedly scrubbed, which can further improve the cleaning effect.

[0035] It should be further explained that the brush is fixedly connected to a moving block 313, and a guide groove 314 is fixedly installed on the cleaning frame 100. The moving block 313 slides in contact with the guide groove 314. The moving block 313 can drive the brush to move back and forth along the guide groove 314 to brush the surface of the rubber blanket.

[0036] Specifically, a slide rod 312 is provided at one end of the guide groove 314, and an elastic element 311 is sleeved on the slide rod 312. The elastic element 311 is a spring, and the moving block 313 is slidably connected to the slide rod 312.

[0037] The other end of the movable block 313 is provided with a sliding groove 3131, the depth of which gradually decreases. Several push blocks 500 are fixedly installed on the chain 202 via a connecting plate 400. During the movement of the chain 202, the push blocks 500 will move along the sliding groove 3131. Due to the different depths of the sliding groove 3131, the push blocks 500 will push the movable block 313 to slide along the guide groove 314 during the movement. During this process, the spring is first compressed. When the push block 500 is disengaged from the movable block 313, the movable block 313 will reset under the force of the spring. This cycle is repeated to realize the reciprocating movement of the movable block 313 and the brush to clean the rubber blanket.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
