Description

Technical Field

[0001] This utility model relates to the field of printing plate cleaning technology, and in particular to a cleaning device for screen printing plates of a screen printing machine. Background Technology

[0002] A screen printing machine is a type of printing machine that uses a screen printing plate for printing. According to the printing method, it can be divided into flat screen printing, curved screen printing, rotary screen printing, etc. The screen printing plate will be contaminated with a lot of ink and impurities during use, and usually a cleaning device is used to clean the screen printing plate.

[0003] However, traditional screen printing machines mostly use a single-sided cleaning method, which cannot clean both sides of the printing plate. This results in serious ink residue inside the mesh and at the edges. At the same time, the large amount of wastewater generated during the cleaning process contains pollutants such as ink and solvents. Existing treatment methods are mostly simple sedimentation or primary filtration, which makes it difficult to achieve effective recycling of water resources. This not only wastes resources but also puts pressure on the environment. Therefore, a screen printing plate cleaning device for screen printing machines is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cleaning device for screen printing plates in a screen printing machine, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cleaning device for screen printing plates of a screen printing machine includes a housing. A motor is fixedly installed on one side of the housing. The output end of the motor rotatably passes through the housing and is fixedly connected to a first lead screw. A circular hole is opened on one side of the housing, and a second lead screw is installed in the circular hole. One end of the second lead screw is rotatably connected to the inner wall of one side of the housing. Two sets of guide rods are installed inside the housing, with two guide rods in each set. The two sets of guide rods are located on both sides of the first and second lead screws, respectively. Each set of guide rods is threaded with a slider on the outer side of both the first and second lead screws. A cleaning component is installed on the opposite side of the two sliders. A transmission component is installed between the first and second lead screws. A water tank is fixedly installed on the inner wall of the bottom side of the housing. A filter plate is installed in the water tank, and an agitation component is installed below the filter plate.

[0007] Preferably, the cleaning assembly includes two sliders with flow dividers fixedly connected to their opposite faces, and multiple nozzles provided on the opposite faces of the two flow dividers. A water pump is fixedly installed on one side of the housing, and an extraction pipe is fixedly installed on the bottom side of the water pump. The other end of the extraction pipe passes through the housing and extends into the water tank.

[0008] Preferably, a delivery pipe is fixedly installed on the top side of the water pump, the other end of the delivery pipe extends into the housing, and flexible hoses are fixedly connected to both sides of the delivery pipe. Both flexible hoses are connected to the delivery pipe, and the other ends of the two flexible hoses are fixedly connected to one side of the two distribution boxes and are evenly distributed and connected to each other.

[0009] Preferably, the transmission assembly includes a first lead screw and a second lead screw, the other ends of which are respectively fixedly sleeved with a first synchronous pulley and a second synchronous pulley, and the first synchronous pulley and the second synchronous pulley share the same first synchronous belt.

[0010] Preferably, the agitation assembly includes a circular hole on one side of the housing and the water tank, with the same rotating rod installed in both holes. One end of the rotating rod is rotatably connected to the inner wall of one side of the water tank, and the other end of the rotating rod and the other end of the first lead screw are respectively fixedly sleeved with a fourth synchronous pulley and a third synchronous pulley. The fourth synchronous pulley and the third synchronous pulley share the same second synchronous belt. Multiple agitation plates are fixedly connected to the outside of the rotating rod. A through hole is opened on one side of the housing, and an input pipe is fixedly installed in the through hole. The other end of the input pipe extends into the water tank.

[0011] Preferably, two fixing plates are fixedly installed on the top side of the housing, and the two fixing plates are located on the outside of the two sets of guide rods and the first lead screw and the second lead screw, respectively.

[0012] Preferably, electric push rods are fixedly connected to the opposite sides of the two fixed plates, the output ends of the two electric push rods pass through the fixed plates and are fixedly connected to clamps, and protective pads are fixedly connected to the opposite sides of the two clamps.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. A transmission assembly consisting of a motor, a first lead screw, a second lead screw, a first synchronous pulley, a second synchronous pulley, and a first synchronous belt drives the slider and the flow divider box to reciprocate between the fixed plates. The nozzles on the flow divider box can spray water from both sides to clean the printing plate. Compared with traditional single-sided cleaning, this method allows the ink on both sides of the printing plate to be washed away at the same time, solving the problem that the traditional method cannot take care of both sides, resulting in ink residue in the mesh and corners. This greatly improves cleaning efficiency and reduces cleaning time and labor costs.

[0015] 2. The filter plate installed in the water tank can intercept particulate ink and other impurities during the return of cleaning wastewater, achieving preliminary filtration and recycling of water resources. At the same time, the agitation assembly, composed of the first lead screw, the third synchronous pulley, the fourth synchronous pulley, the second synchronous belt, the rotating rod, and the agitator plate, can fully mix the purification agent with the water source when adding the purification agent, thus purifying the water quality. This effectively solves the problem of simple wastewater treatment and difficulty in recycling water resources in traditional cleaning devices, reducing resource waste, alleviating environmental pressure, and ensuring the continuous operation of cleaning.

[0021] 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.

[0022] Reference Figure 1-4A cleaning device for screen printing plates of a screen printing machine includes a housing 1. A motor 4 is fixedly installed on one side of the housing 1. The output end of the motor 4 rotatably passes through the housing 1 and is fixedly connected to a first lead screw 5. A circular hole is opened on one side of the housing 1, and a second lead screw 7 is installed in the circular hole. One end of the second lead screw 7 is rotatably connected to the inner wall of one side of the housing 1. Two sets of guide rods 10 are installed inside the housing 1, with two guide rods in each set. The two sets of guide rods 10 are located on both sides of the first lead screw 5 and the second lead screw 7, respectively. Each set of guide rods 10 is threadedly connected to the outer side of the first lead screw 5 and the second lead screw 7, respectively, with a slider 11. Cleaning components are provided on the opposite sides of the two sliders 11. A transmission component is provided between the first lead screw 5 and the second lead screw 7. A water tank 2 is fixedly installed on the inner wall of the bottom side of the housing 1. A filter plate 3 is installed in the water tank 2, and an agitation component is provided below the filter plate 3. The transmission component includes the first lead screw 5 and the second lead screw 7. The other end of the second lead screw 7 is fixedly sleeved with the first synchronous pulley 6 and the second synchronous pulley 8 respectively. The first synchronous pulley 6 and the second synchronous pulley 8 share the same first synchronous belt 9. With the motor 4 installed, the motor 4 is started during the water spraying process, which drives the first lead screw 5 to rotate. Since the first synchronous pulley 6 and the second synchronous pulley 8 fixedly sleeved on the outside of the first lead screw 5 share the same first synchronous belt 9, the second synchronous pulley 8 will synchronously drive the second lead screw 7 connected to it to rotate under the meshing transmission of the first synchronous belt 9. This causes the slider 11, which is threadedly sleeved on the outside of both the first lead screw 5 and the second lead screw 7, to drive the diversion box 12 to move back and forth between the two fixed plates 18. During the movement of the diversion box 12, the water sprayed by the two sets of nozzles 13 will wash away the ink attached to both sides of the printing plate. Compared with the traditional single-sided cleaning method, double-sided cleaning can greatly improve the cleaning speed of the printing plate.

[0023] Specifically, the cleaning assembly includes two sliders 11, each with a diversion box 12 fixedly connected to its opposite surface. Multiple nozzles 13 are provided on the opposite surfaces of the two diversion boxes 12. A water pump 14 is fixedly installed on one side of the housing 1. An extraction pipe 15 is fixedly installed on the bottom side of the water pump 14, with the other end of the extraction pipe 15 penetrating the housing 1 and extending into the water tank 2. A delivery pipe 16 is fixedly installed on the top side of the water pump 14, with the other end of the delivery pipe 16 extending into the housing 1. Flexible hoses are fixedly connected to both sides of the delivery pipe 16. 17. Both hoses 17 are connected to the delivery pipe 16. The other ends of the two hoses 17 are fixedly connected to one side of the two distribution boxes 12 and are evenly connected to the distribution boxes 12. A water pump 14 is provided. After the printing plate is clamped securely, the water pump 14 is started to drive the extraction pipe 15 to draw water from the water tank 2. The water is delivered to the two hoses 17 through the delivery pipe 16 and then sprayed out through multiple nozzles 13 provided on one side of the two distribution boxes 12, thereby realizing double-sided cleaning of the printing plate.

[0024] Specifically, the agitation assembly includes a circular hole on one side of both the housing 1 and the water tank 2. A rotating rod 20 is installed in both holes. One end of the rotating rod 20 is rotatably connected to the inner wall of one side of the water tank 2. The other end of the rotating rod 20 and the other end of the first lead screw 5 are respectively fixedly sleeved with a fourth synchronous pulley 21 and a third synchronous pulley 19. The fourth synchronous pulley 21 and the third synchronous pulley 19 share the same second synchronous belt 22. Multiple agitator plates 23 are fixedly connected to the outside of the rotating rod 20. A through hole is opened on one side of the housing 1, and an input pipe is fixedly installed in the through hole. 24. The other end of the input pipe 24 extends into the water tank 2, and the third synchronous pulley 19 is fixedly sleeved to the other end of the first screw 5. The third synchronous pulley 19 and the fourth synchronous pulley 21 share the same second synchronous belt 22. Therefore, under the meshing transmission of the second synchronous belt 22, the fourth synchronous pulley 21 will drive the rotating rod 20 connected to it to rotate synchronously, thereby causing the multiple stirring plates 23 fixedly connected to the outside of the rotating rod 20 to stir in the water tank 2, so as to fully mix the water source with the agent, so as to ensure that the water source subsequently extracted can avoid turbidity.

[0025] Specifically, two fixing plates 18 are fixedly installed on the top side of the housing 1. The two fixing plates 18 are located on the outside of the two sets of guide rods 10 and the first lead screw 5 and the second lead screw 7, respectively. Electric push rods 25 are fixedly connected to the opposite sides of the two fixing plates 18. The output ends of the two electric push rods 25 pass through the fixing plates 18 and are fixedly connected to clamping plates 26. Protective pads are fixedly connected to the opposite sides of the two clamping plates 26. By setting two clamping plates 26, when it is necessary to clamp the printing plate, the printing plate to be cleaned is placed between the two clamping plates 26. Then, the electric push rods 25 are started simultaneously to drive the two clamping plates 26 to move closer to each other, thereby completing the clamping of the printing plate. After the printing plate is firmly clamped, the rinsing process can begin. The distance between the two clamping plates 26 can be adjusted by the electric push rods 25, so that printing plates of different sizes can be clamped, thereby greatly improving the applicability of this cleaning device.

[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0027] In use: When cleaning printing plates, place the printing plate to be cleaned between two clamping plates 26, and simultaneously start the electric push rod 25 to drive the two clamping plates 26 to move towards each other, thereby achieving a stable clamping of the printing plate. After the printing plate is fixed, start the water pump 14 to draw water from the water tank 2 through the extraction pipe 15. The water source is distributed to two hoses 17 through the delivery pipe 16, and then evenly sprayed out by multiple nozzles 13 on the sides of the two distribution boxes 12. In order to ensure that both sides of the printing plate are thoroughly cleaned, start the motor 4 to drive the first lead screw 5 to rotate. Since the first synchronous wheel 6 and the second synchronous wheel 8, which are fixedly sleeved on the outside of the first lead screw 5, are connected through the first synchronous belt 9, the second synchronous wheel 8 will drive the second lead screw 7 to rotate synchronously under the meshing transmission action of the synchronous belt. At this time, the slider 11, which is threadedly sleeved on the outside of the first lead screw 5 and the second lead screw 7, will drive the distribution box 12 to reciprocate between the two fixed plates 18. The linear motion allows the water jets from the two sets of nozzles 13 to thoroughly wash the ink adhering to both sides of the printing plate, achieving efficient cleaning. The wastewater after cleaning flows back to the water tank 2, where the filter plate 3 effectively intercepts particulate ink and other impurities, allowing the filtered water to flow back into the water tank 2 for recycling. When the water in the water tank 2 becomes turbid, a purifying agent can be added to the water tank 2 through the inlet pipe 24. At this time, when the motor 4 rotates, the third synchronous wheel 19, which is fixedly sleeved at the other end of the first lead screw 5, will drive the fourth synchronous wheel 21 to rotate through the second synchronous belt 22, thereby causing the rotating rod 20 connected to it to start rotating. The multiple agitator plates 23 fixedly connected to the outside of the rotating rod 20 will then agitate the water flow in the water tank 2, promoting thorough mixing of the agent and the water, quickly completing water purification, ensuring the cleanliness of the subsequent cleaning water, and maintaining the continuity and efficiency of the cleaning operation.
