Abstract
Description
Technical Field
[0001] This utility model belongs to the field of printing technology, and in particular relates to a pre-press plate washing device. Background Technology
[0002] Prepress plate cleaning is mainly used to clean printing plates before printing to remove dirt, old ink, and other impurities, ensuring printing quality and results. It is one of the key pieces of equipment in the prepress process, playing a crucial role in improving the clarity and color reproduction of printed materials. The equipment achieves rapid and efficient cleaning of printing plates through automated means such as high-pressure water jets and brushing mechanisms.
[0003] The plate washing device uses water flow to clean the printing plate. The water flow after cleaning the printing plate will contain impurities, which will affect the reuse of water. The wastewater after cleaning the printing plate needs to be filtered before it can be used. Therefore, filter plates are set up to filter the wastewater. However, after long-term use, a large amount of dirt and impurities will gradually accumulate, causing the filter pores to become blocked, thereby reducing the filtration efficiency. Therefore, we propose a pre-press plate washing device. Utility Model Content
[0004] The purpose of this invention is to provide a pre-press plate washing device. By setting up a filter assembly, the filter plate allows the water used to clean the surface of the printing plate to be reused. The convenient disassembly and installation of the filter plate allows for quick cleaning and replacement of the filter plate, thereby reducing the impact of filter plate replacement on the working efficiency of the equipment. This solves the problem that after long-term use, a large amount of dirt and impurities will gradually accumulate, causing the filter pores to become clogged and thus reducing the filtration efficiency.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a pre-press plate washing device, including an operating table. A tray is fixedly connected to the left side of the operating table, a motor is fixedly connected to the front of the operating table, a cover plate is rotatably connected to the top of the operating table, a roller is fixedly connected to the output end of the motor, and the front and back of the roller are rotatably connected to the inner wall of the operating table. A water spray pipe is provided on the right side of the roller. The water sprayed from the water spray pipe impacts the surface of the roller, which can effectively clean the stains remaining on the surface of the roller.
[0007] The operating table is equipped with a filtration assembly, which includes a fixed box fixedly connected to the inner wall of the bottom of the operating table. A filter plate is slidably connected to the inner wall of the fixed box. Two rods are fixedly connected to the side wall of the filter plate. A gear is provided on the side of the fixed box away from the filter plate. A knob is fixedly connected to the side of the gear away from the fixed box. Racks are meshed on the left and right sides of the gear. Limit blocks are fixedly connected to the ends of the two racks that are far apart from each other. Limit holes are opened on the sides of the two rods that are far apart from each other. The outer surfaces of the two gears are inserted into the inner walls of the limit holes. After cleaning, the filter plate is inserted into the fixed box to fix it in place. The filter plate allows the water used to clean the stains on the printing plate surface to be reused. The convenient disassembly and installation of the filter plate allows for quick cleaning and replacement of the filter plate, thereby reducing the impact of filter plate replacement on the working efficiency of the equipment.
[0008] Furthermore, two L-shaped grooves are provided on the side of the fixed box away from the filter plate. The two racks are slidably connected to the inner wall of the L-shaped grooves on the side of the fixed box through connecting blocks. A limiting shaft is fixedly connected to the side of the gears near the fixed box. The outer surface of the limiting shaft is rotatably connected to the inner wall of the fixed box. The racks can move without disengaging from the surface of the fixed box through the connecting blocks.
[0009] Furthermore, a water tank is placed on the bottom inner wall of the operating table, and a water inlet pipe is fixedly connected to the front of the water tank. The side wall of the water tank is connected to the bottom of the fixed box through the water inlet pipe. The filtered water is recycled back into the water tank through the water inlet pipe and can be reused.
[0010] Furthermore, a water outlet pipe is fixedly connected to the back of the water tank, and the side wall of the water tank is connected to the end of the spray pipe away from the motor through the water outlet pipe. Several cleaning cylinders are provided on the right side of the spray pipe. The front and back of the cleaning cylinders are rotatably connected to the inner wall of the operating table. The printing plate after being cleaned by the roller is transported to the bottom of the cleaning cylinder, and after being wiped by the cleaning cylinder, it is finally moved to the outside.
[0011] Furthermore, a support assembly is provided on the side of the cover plate near the motor. The support assembly includes a rotating rod rotatably connected to the inner wall of the operating table. A sliding groove is provided on the side of the cover plate near the rotating rod. A slider is slidably connected to the inner wall of the sliding groove. The end of the slider near the rotating rod is rotatably connected to the end of the rotating rod near the cover plate. As the cover plate rotates, the cover plate drives the rotating rod to rotate synchronously through the slider, and the rotating rod provides effective support for the cover plate.
[0012] Furthermore, a screw is fixedly connected to the side of the slider away from the slide groove, and a nut is threaded onto the outer surface of the screw. When the slider moves to the top of the slide groove, the nut on the surface of the screw is rotated clockwise to fix the slider to the inner wall of the slide groove. At this time, the operator can inspect the inside of the operating table and fix the cover plate to prevent the inspection cover from closing accidentally or falling off.
[0013] This utility model has the following beneficial effects:
[0014] This invention features a filter assembly. Specifically, rotating the knob clockwise drives the gear to rotate, which in turn moves the racks on both sides. The limiting blocks at the ends of the racks disengage from the insert rod, allowing the filter plate to be removed from the fixed box. After cleaning, the filter plate is reinserted into the fixed box to secure it. The filter plate allows the water used to clean the printing plate surface to be reused, and the convenient disassembly and installation of the filter plate enables quick cleaning and replacement, thereby reducing the impact of filter plate replacement on equipment efficiency.
[0015] This utility model features a support assembly. Specifically, when the cover is opened, it rotates, causing a slider to drive a rotating rod to rotate synchronously. As the cover rotates, the slider slides along the inner wall of the groove. When the slider reaches the top of the groove, the nut on the screw surface is rotated clockwise to fix the slider to the inner wall of the groove. At this point, the operator can inspect the inside of the workbench and secure the cover, thus preventing the maintenance cover from accidentally closing or falling off, thereby avoiding injury to maintenance personnel. The maintenance cover can be easily opened and secured without complicated steps or tools.
[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Limit holes are opened on the sides of the two insert rods 203 that are away from each other. The outer surfaces of the two gears 205 are aligned with the inner surfaces of the limit holes. The filter assembly 2 is installed in a wall-mounted manner. Specifically, rotating the knob 206 clockwise drives the gear 205 to rotate. As the gear 205 rotates, it drives the racks 207 on both sides to move. The limiting blocks 208 at the ends of the racks 207 on both sides disengage from the inside of the insert rod 203. At this time, the filter plate 201 can be taken out from the inside of the fixed box 202. After cleaning, the filter plate 201 is inserted back into the fixed box 202 to fix it in place. The filter plate 201 allows the water used to clean the stains on the printing plate surface to be reused. The convenient disassembly and installation of the filter plate 201 allows for quick cleaning and replacement of the filter plate 201, thereby reducing the impact of replacing the filter plate 201 on the working efficiency of the equipment.
[0029] Two L-shaped grooves are provided on the side of the fixed box 202 away from the filter plate 201. The two racks 207 are slidably connected to the inner wall of the L-shaped grooves through connecting blocks on the side of the fixed box 202. The gear 205 is fixedly connected to the side of the fixed box 202 with a limiting shaft 204. The outer surface of the limiting shaft 204 is rotatably connected to the inner wall of the fixed box 202.
[0030] A water tank 105 is placed on the bottom inner wall of the operating table 1. A water inlet pipe 302 is fixedly connected to the front of the water tank 105. The side wall of the water tank 105 is connected to the bottom of the fixed box 202 through the water inlet pipe 302.
[0031] A water outlet pipe 301 is fixedly connected to the back of the water tank 105. The side wall of the water tank 105 is connected to the end of the spray pipe 106 away from the motor 102 through the water outlet pipe 301. Several cleaning cylinders 303 are provided on the right side of the spray pipe 106. The front and back of the several cleaning cylinders 303 are rotatably connected to the inner wall of the operating table 1.
[0032] A support assembly 4 is provided on the side of the cover plate 103 near the motor 102. The support assembly 4 includes a rotating rod 401 that is rotatably connected to the inner wall of the operating table 1.

[0034] A screw 403 is fixedly connected to the side of the slider 402 away from the slide groove 405. A nut 404 is threaded onto the outer surface of the screw 403. By setting the support component 4, specifically by opening the cover plate 103, as the cover plate 103 rotates, the cover plate 103 drives the rotating rod 401 to rotate synchronously through the slider 402. As the rotation angle of the cover plate 103 changes, the slider 402 slides on the inner wall of the slide groove 405. When the slider 402 moves to the top of the slide groove 405, the nut 404 on the surface of the screw 403 is rotated clockwise to fix the slider 402 to the inner wall of the slide groove 405. At this time, the operator can inspect the inside of the operating table 1 and fix the cover plate 103 to prevent the maintenance cover from closing accidentally or falling off, thereby avoiding injury to the maintenance personnel. The maintenance cover can be easily opened and fixed without complicated steps or tools.
[0035] A specific application of this embodiment is as follows: The printing plate is placed from the tray 101 into the operating table 1. The printing plate passes through the bottom of the roller 104 and falls onto the roller surface. The roller rotates under system control, driving the printing plate. The water cleaning solution inside the water tank 105 is delivered to the water outlet pipe 301 by a booster pump, and finally enters the water spray pipe 106 and is sprayed onto the surface of the roller 104 through the nozzle. The motor 102 is started to drive the roller 104 to rotate. As the roller 104 rotates, the surface stains of the printing plate are cleaned. The cleaned stains enter the surface of the filter plate 201 at the bottom of the operating table 1 with the water flow. The water passing through the filter plate 201 enters the fixed box 202 and finally flows into the water tank 105 through the water inlet pipe 302, forming a cycle. After working for a long time, the filter plate 201 rotates clockwise. The knob 206 drives the gear 20 5. As gear 205 rotates, it drives the racks 207 on both sides to move. The limiting blocks 208 at the ends of the racks 207 on both sides disengage from the inside of the insert rod 203. At this time, the filter plate 201 can be taken out from the inside of the fixed box 202. After cleaning, the filter plate 201 is inserted back into the inside of the fixed box 202. The filter plate 201 moves to the inner wall of the fixed box 202 and fits against it. At this time, turn the knob 206 counterclockwise. Through gear 205, the limiting blocks 208 on both sides move closer to each other. The limiting blocks 208 move into the limiting holes opened in the insert rod 203 and fix the filter plate 201. The filter plate 201 allows the water after cleaning the stains on the printing plate surface to be reused. The convenient disassembly and installation of the filter plate 201 can quickly clean and replace the filter plate 201, thereby reducing the impact of replacing the filter plate 201 on the working efficiency of the equipment.
[0036] After being cleaned by roller 104, the printing plate is transported to the bottom of cleaning cylinder 303. After being wiped by cleaning cylinder 303, it is finally moved to the outside. When it is necessary to inspect the inside of the operating table 1, the cover plate 103 is opened. As the cover plate 103 rotates, the cover plate 103 drives the rotating rod 401 to rotate synchronously through the slider 402. As the rotation angle of the cover plate 103 changes, the slider 402 slides on the inner wall of the slide groove 405. When the slider 402 moves to the top of the slide groove 405, the nut 404 on the surface of the screw 403 is rotated clockwise to fix the slider 402 to the inner wall of the slide groove 405. At this time, the staff can inspect the inside of the operating table 1. The cover plate 103 is fixed to prevent the inspection cover from closing accidentally or falling off, thereby avoiding injury to the maintenance personnel. The inspection cover can be opened and fixed easily without complicated steps or tools.
