Description

Technical Field

[0001] This application relates to the field of printing technology, and particularly to a plate cleaning machine. Background Art

[0002] A printing plate is a carrier for transferring a color former or colorant (such as ink, etc.) to a printing substrate for reproducing graphics and texts.

[0003] During the use of a printing plate, some ink will adhere to it. For the convenience of the next printing, these printing plates with adhered ink need to be cleaned to avoid affecting the printing quality of the next printing.

[0004] Currently, most of the cleaning methods for these printing plates with adhered ink are manual cleaning. The cleaning workers use tools such as brushes to rub on the surface of the printing plate. The cleaning efficiency is low. After cleaning, manual drying and other operations are also required. Moreover, the cleaning intensity is not easy to control. At difficult-to-clean positions, the cleaning workers will inevitably increase the cleaning intensity, which is very likely to cause damage to the printing structure on the printing plate, resulting in the scrapping of the entire printing plate.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Apparently, the described embodiments are some, rather than all, of the embodiments of the present application.

[0048] Figure 1 A perspective view of a plate cleaning machine provided by an embodiment of this application. Figure 2 A cross-sectional view of a plate cleaning machine provided by an embodiment of this application. Figure 3 is Figure 2 A partial enlarged view of part A in Figure 4 A perspective view of a frame used in a plate cleaning machine provided by an embodiment of this application.

[0049] An embodiment of this application provides a plate cleaning machine, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, including a frame 100, a cleaning tank 150, a water tank 200, a conveying assembly 250, a cleaning assembly 350, a spray pipe 500, and a drying assembly 550. Among them, the frame 100 is a structure for installing and supporting other components, the cleaning tank 150 is a place for cleaning the plate, the water tank 200 contains water (or cleaning agent), the conveying assembly 250 is used to convey the plate, the spray pipe 500 is used to spray the water (or cleaning agent) in the water tank 200 onto the plate, the cleaning assembly 350 is used to clean the plate, and the drying assembly 550 is used to dry the cleaned plate.

[0050] As Figure 2 and Figure 4 shown, the cleaning tank 150 is arranged on the frame 100. The cleaning tank 150 is generally arranged in the upper middle part of the frame 100 for the convenience of placing the water tank 200. The cleaning tank 150 is a trough member with an open upper end, generally having a cuboid structure and can be welded by steel plates.

[0051] The water tank 200 is arranged on the frame 100. The water tank 200 is located below the cleaning tank 150 and is connected to the cleaning tank 150 through a pipe. The water tank 200 contains water (or cleaning agent), which can be appropriately replaced according to the type of ink on the plate to facilitate the cleaning of the ink.

[0052] As Figure 2 shown, the conveying assembly 250 is disposed on the frame 100 and above the cleaning tank 150. The conveying assembly 250 conveys the printing plate in the first direction, causing the printing plate to move in the first direction.

[0053] As Figure 2 and Figure 3 shown, the cleaning assembly 350 includes a brush roller 360 and a brush plate 370 for cleaning the conveyed printing plate. The brush roller 360 and the brush plate 370 rub the upper surface of the printing plate to clean off the ink.

[0054] As Figure 3 shown, the spray pipe 500 is disposed above the brush roller 360 and the brush plate 370 and sprays downward. The spray pipe 500 is communicated with the water tank 200 through a delivery pump. The delivery pump pumps the water (or cleaning agent) in the water tank 200 into the spray pipe 500 and sprays it out from the spray pipe 500 onto the printing plate, cooperating with the cleaning assembly 350 to complete the cleaning of the printing plate.

[0055] As Figure 2 shown, the drying assembly 550 is disposed on the frame 100 and in front of the conveying assembly 250 in the first direction. That is to say, the printing plate reaches the drying assembly 550 after coming out of the conveying assembly 250, thereby drying the cleaned printing plate.

[0056] After the installation of each component is completed, structures such as shields and guard plates can be provided around the frame 100. The frame 100 generally forms a box structure, which can prevent the staff from contacting the moving components and improve the safety of the equipment.

[0057] In addition, an emergency stop button can be provided on the frame 100. When an emergency occurs, the staff can press the emergency stop button to stop the entire equipment.

[0058] Compared with the prior art, the printing plate cleaning machine realizes the conveyance of the printing plate through the conveying assembly 250. During the conveyance process, the water (or cleaning agent) in the water tank 200 is sprayed onto the printing plate through the spray pipe 500, and the brush roller 360 and the brush plate 370 of the cleaning assembly 350 clean the printing plate. During the cleaning process, the cleaned water (or cleaning agent) enters the cleaning tank 150 and finally flows into the water tank 200 for cyclic cleaning. The cleaned printing plate continues to be conveyed forward, and the drying assembly 550 dries the cleaned printing plate. Through the above structure, the cleaning of the printing plate is realized, avoiding the manual cleaning method, reducing the possibility of damage to the printing plate, and drying after cleaning, avoiding manual drying and improving the cleaning efficiency.

[0059] It should be noted that taking water as the cleaning liquid as an example, the water in the water tank 200 is sprayed out from the spray pipe 500 through a delivery pump to clean the printing plate, then enters the cleaning tank 150, and finally returns to the water tank 200, and can continue to circulate for cleaning. After cleaning for a period of time, the overall concentration of the liquid in the water tank 200 becomes larger, the water becomes dirty, the cleaning effect on the printing plate decreases, the ink with a larger density settles at the bottom, and the water floats on the upper part. Therefore, a clean water container can be additionally provided to hold clean water, which is also sprayed onto the printing plate through a delivery pump and the spray pipe 500. Thus, on the one hand, the printing plate can be rinsed with clean water, and on the other hand, the rinsed water enters the water tank 200, increasing the liquid in the water tank 200. At this time, the ink at the bottom of the water tank 200 can be discharged into a sewage container, thereby reducing the overall concentration of the liquid in the water tank 200 and making the water cleaner. By circulating in this way, it is convenient to clean the printing plate thoroughly. When the cleaning agent is placed in the water tank 200, clean cleaning agent should be placed in the clean water container.

[0060] Figure 5 It is a perspective view of a conveying assembly used in a printing plate cleaning machine provided by an embodiment of the present application.

[0061] In some embodiments, as Figure 3 、 Figure 4 and Figure 5 shown, the conveying assembly 250 includes a mounting plate 260, a driving motor 270, a main transmission shaft 280, a plurality of first conveying rollers 290 and a plurality of second conveying rollers 300. The number of mounting plates 260 is two. The two mounting plates 260 can be mounted on two opposite tank walls of the cleaning tank 150 (it can also be understood that the mounting plates 260 extend upward from two opposite tank walls of the cleaning tank 150) or mounted on the frame 100, as long as the conveying assembly 250 can be generally located above the cleaning tank 150, so that the printing plate is located above the cleaning tank 150 during conveying.

[0062] As [[ID=|17]] Figure 3 、 Figure 4 and Figure 5 shown, the driving motor 270 is mounted on the mounting plate 260. The main transmission shaft 280 is in transmission connection with the driving motor 270. The main transmission shaft 280 extends in a first direction. When the main transmission shaft 280 is installed, it can be installed on the cleaning tank 150, close to the tank wall of the cleaning tank 150. A plurality of worm gears 281 are provided on the main transmission shaft 280. The plurality of worm gears 281 are arranged at intervals along the axial direction of the main transmission shaft 280. The number of worm gears 281 is equal to the number of the first conveying rollers 290 and is arranged in one-to-one correspondence.

[0063] As Figure 5As shown, during installation, the drive motor 270 and the main transmission shaft 280 are located on both sides of the mounting plate 260. The drive motor 270 is installed on the mounting plate 260 through the motor bracket and the output shaft extends in the first direction. Then, a transmission connection is achieved with the main transmission shaft 280 through a synchronous belt passing through the mounting plate 260, so that the main transmission shaft 280 also extends in the first direction. One end of the main transmission shaft 280 is transmission-connected to the drive motor 270, and the other end is rotatably connected to the tank wall of the cleaning tank 150.

[0064] In addition, the driving motor 270 can also be installed on the frame 10 as long as it can be stably installed, and this is not limited here.

[0065] Generally, unless otherwise specified, the drive motor 270 is a right-hand motor, which is a common type on the market.

[0066] like Figure 3 and Figure 5 As shown, multiple first conveying rollers 290 are arranged at intervals along the first direction and extend along the second direction. The first conveying rollers 290 are rotatably arranged relative to the mounting plate 260. The second direction is perpendicular to the first direction. Each first conveying roller 290 is provided with a worm gear at one end close to the main transmission shaft 280. The worm gear cooperates with the worm 281. When the main transmission shaft 280 rotates, the worm gear can be driven to rotate by the worm 281, thereby driving the first conveying roller 290 to rotate.

[0067] like Figure 3 and Figure 5 As shown, a plurality of second conveyor rollers 300 are spaced apart along the first direction and extend along the second direction. The number of second conveyor rollers 300 is equal to the number of first conveyor rollers 290. The second conveyor rollers 300 are rotatably mounted relative to the mounting plate 260, and the plurality of second conveyor rollers 300 are disposed one-to-one above the first conveyor rollers 290. When a printing plate enters from one end of the conveyor assembly 250, the first conveyor rollers 290 are positioned below the printing plate and act as active rollers, driving the printing plate in the first direction. The second conveyor rollers 300 are positioned above the printing plate and act as driven rollers, rotating with the printing plate.

[0068] The above structure realizes the conveyance of the printing plate, and each first conveying roller 290 is driven by the same main transmission shaft 280, and the rotation speed of each first conveying roller 290 is equal, so the conveyance is smooth.

[0069] In order to accommodate printing plates of different thicknesses, in some embodiments, as Figure 3 and Figure 5As shown in the figure, a lifting limit groove 310 is provided on the mounting plate 260. The lifting limit groove 310 is vertically arranged, and the notch of the lifting limit groove 310 faces another mounting plate 260. A first lifting block 311 is arranged in the lifting limit groove 310. The side wall of the first lifting block 311 along the first direction abuts against the groove wall of the lifting limit groove 310, so that it can move in the vertical direction to achieve lifting. The second conveying roller 300 is rotationally connected to the first lifting block 311. Through the above structure, the gap between the first conveying roller 290 and the second conveying roller 300 is adjustable, so as to adapt to printing plates of different thicknesses.

[0070] During production, the first conveying roller 290 can be made into a rubber roller, and the second conveying roller 300 can be made into a foaming roller. The rubber roller will not damage the printing plate when it contacts the printing plate. The foaming roller is easy to absorb water and ink on the printing plate, and has a good cleaning effect.

[0071] In some embodiments, as Figure 3 and Figure 5 shown, a second lifting block 312 and a spring 313 are further arranged in the lifting limit groove 310. The side wall of the second lifting block 312 along the first direction abuts against the groove wall of the lifting limit groove 310, so as to achieve vertical movement and realize lifting. A pressure roller 314 is rotationally connected to the second lifting block 312. The pressure roller 314 abuts above the second conveying roller 300. The upper end of the spring 313 is fixed on the lifting limit groove 310, and the lower end of the spring 313 is connected to the second lifting block 312. The second conveying roller 300 is extruded by the gravity of the pressure roller 314 and the elastic force of the spring 313, so as to increase the friction between the second conveying roller 300 and the printing plate and avoid slipping.

[0072] In some embodiments, as Figure 3 and Figure 4 shown, the cleaning assembly 350 includes a first cleaning motor 380, a second cleaning motor 390, a brush roller 360, a brush plate 370 and two support plates 400. The first cleaning motor 380 is used to drive the brush roller 360 to move, and the second cleaning motor 390 is used to drive the brush plate 370 to move.

[0073] As Figure 3 and Figure 4As shown, the first cleaning motor 380 is installed on the mounting plate 260. The first cleaning motor 380 is drivingly connected to the brush roller 360 to drive the brush roller 360 to rotate around an axis extending in the second direction. A support plate 400 is provided below the brush roller 360 for supporting the printing plate. That is to say, the printing plate is between the brush roller 360 and the support plate 400, and the brush roller 360 is above the printing plate. Its rotation direction should be the same as that of the second conveying roller 300, that is, opposite to the rotation direction of the first conveying roller 290. The first conveying roller 290 is driven by the drive motor 270. That is to say, the rotation direction of the first cleaning motor 380 should be opposite to the rotation direction of the drive motor 270, that is, left-handed rotation.

[0074] As Figure 3 and Figure 4 shown, the second cleaning motor 390 is installed on the mounting plate 260. The second cleaning motor 390 is drivingly connected to the brush plate 370 to drive the brush plate 370 to reciprocally swing along the second direction. Another support plate 400 is provided below the brush plate 370 for supporting the printing plate. That is to say, the printing plate is located between the brush plate 370 and the support plate 400, and the brush plate 370 reciprocally rubs and cleans the upper surface of the printing plate.

[0075] Figure 6 It is a three-dimensional installation view of the brush roller used in a printing plate cleaning machine provided by an embodiment of the present application.

[0076] Specifically, in some embodiments, as Figure 5 and Figure 6 shown, the cleaning assembly 350 further includes a first alignment fixing sleeve 410, a first transmission shaft 420, a first swing wheel 430 and a first rolling bearing 440. The first alignment fixing sleeve 410 is fixed to the mounting plate 260. The first transmission shaft 420 extends in the second direction and is slidably connected within the first alignment fixing sleeve 410. The brush roller 360 is coaxially fixed to the first transmission shaft 420 and moves together with the first transmission shaft 420.

[0077] For the convenience of installation, in actual implementation, both ends of the first transmission shaft 420 can be first installed on two supporting shafts. One end of the supporting shaft is slidably connected within the first alignment fixing sleeve 410, and the supporting shaft at the other end is rotatably connected to the mounting plate 260.

[0078] The first swing wheel 430 is meshed and driven with the first cleaning motor 380 through a gear. The first swing wheel 430 extends in the second direction. The first swing wheel 430 is provided with a first swing slideway 431. The first swing slideway 431 surrounds the axis of the first swing wheel 430 for one week. The surrounding path of the first swing slideway 431 forms a first planar ring and the angle between the first planar ring and the axis of the first swing wheel 430 is an acute angle. That is to say, the first swing slideway 431 is an inclined trough shape.

[0079] As shown Figure 5 in FIG. 2, the first rolling bearing 440 is fixed to the mounting plate 260 through the first support plate, and the first rolling bearing 440 is slidably disposed in the first swing slideway 431.

[0080] When the first cleaning motor 380 is started, it drives the first swing wheel 430 to rotate. The first rolling bearing 440 slides in the first swing slideway 431. Since the position of the first rolling bearing 440 does not change, the first swing wheel 430 can perform reciprocating movement in the second direction while rotating, thereby driving the brush roller 360 to reciprocate in the second direction while rotating, so as to clean the printing plate, and the effect is very good.

[0081] Figure 7 FIG. 10 is a perspective view of the installation of the brush plate used in a printing plate cleaning machine provided by an embodiment of the present application.

[0082] In some embodiments, as shown Figure 5 in FIGS. 12 and 13, the cleaning assembly 350 further includes a second centering fixing sleeve 450, a second transmission shaft 460, a second swing wheel 470 and a second rolling bearing 480. The second centering fixing sleeve 450 is fixed to the mounting plate 260, and the second transmission shaft 460 extends in the second direction and is slidably connected to the second centering fixing sleeve 450. Figure 7 For the convenience of installation, in actual implementation, both ends of the second transmission shaft 460 can be first installed on two supporting shafts. One end of the supporting shaft is slidably connected to the second centering fixing sleeve 450, and the other end of the supporting shaft is rotatably connected to the mounting plate 260.

[0083] As shown in FIG. 14, the brush plate 370 is provided with a fixing block 371 and two limiting sleeves 372. The fixing block 371 is provided with a through hole, and the second transmission shaft 460 is rotatably connected to the through hole. The two limiting sleeves 372 are sleeved on the second transmission shaft 460 and are located on both sides of the fixing block 371. The limiting sleeve 372 and the second transmission shaft 460 are fixed by a shaft pin, so that the second transmission shaft 460 can rotate relative to the brush plate 370, and at the same time, the second transmission shaft 460 is relatively fixed to the brush plate 370 in the second direction through the two limiting sleeves 372.

[0084] As shown Figure 7 in FIG. 15, the second swing wheel 470 is in meshing transmission with the second cleaning motor 390 through a gear. The second swing wheel 470 is provided with a second swing slideway 471. The second swing slideway 471 surrounds the axis of the second swing wheel 470 for one week. The surrounding path of the second swing slideway 471 forms a second plane ring, and the angle between the second plane ring and the axis of the second swing wheel 470 is an acute angle. That is to say, the second swing slideway 471 is an inclined groove shape.

[0085] The second rolling bearing 480 is slidably disposed in the second swing slideway 471. When the second cleaning motor 390 is started, it drives the second swing wheel 470 to rotate. The second rolling bearing 480 slides in the second swing slideway 471. Since the position of the second rolling bearing 480 does not change, the second swing wheel 470 can perform reciprocating movement in the second direction while rotating, and then drive the second transmission shaft 460 to reciprocate in the second direction while rotating, so as to drive the brush plate 370 to reciprocate in the second direction while rotating, and further clean the printing plate, and the cleaning effect is better.

[0086] As shownFigure 5 and Figure 7 As shown in Figure 7 , the second rolling bearing 480 is fixed to the mounting plate 260 through the second support plate, and the second rolling bearing 480 is slidably disposed within the second swing slideway 471.

[0087] When the second cleaning motor 390 is started, it drives the second swing wheel 470 to rotate. The second rolling bearing 480 slides within the second swing slide. Since the position of the second rolling bearing 480 does not change, the first swing wheel 430 can reciprocate in the second direction while rotating, thereby driving the brush plate 370 to reciprocate in the second direction and perform reciprocating friction cleaning on the printing plate, with a very good effect.

[0088] Through the above brush roller 360 and brush plate 370, rolling friction cleaning of the printing plate in the first direction and reciprocating friction cleaning in the second direction can be achieved, improving the cleaning effect of the printing plate and avoiding problems such as cleaning dead spots.

[0089] In some embodiments, as Figure 2 shown, the drying assembly 550 includes a drying duct 560 and a gas source. The drying duct 560 is in communication with the gas source, and an air outlet nozzle is provided on the drying duct 560. The printing plate conveyed from the conveying assembly 250 has been cleaned, and more or less some water droplets will adhere to its upper surface. The gas blown out through the drying duct 560 is used to dry the printing plate.

[0090] In some embodiments, as Figure 1 and Figure 2 shown, the printing plate cleaning machine further includes a feeding assembly 600. The feeding assembly 600 is disposed behind the cleaning tank 150 in the first direction (i.e., Figure 2 the right side in

[0091] ). A conveyor belt 610 is provided on the feeding assembly 600. The transmission shaft passes through the side wall of the cleaning tank 150 in the first direction. One end of the transmission shaft close to the feeding assembly 600 is in transmission connection with the transmission shaft of the conveyor belt 610 through a speed reducer. During use, the printing plate to be cleaned is laid flat on the conveyor belt 610. When the transmission shaft rotates, it drives the transmission shaft of the conveyor belt 610 to rotate, thereby driving the printing plate to move towards the conveying assembly 250 (i.e., move in the a direction), achieving a very good feeding effect without the need for manual holding of the printing plate. Additionally, a guiding structure can be provided at one end of the feeding assembly 600 close to the conveying assembly 250 to facilitate feeding more conveniently. Figure 1 and Figure 2As shown, the plate cleaning machine further includes a receiving bag 650. The receiving bag 650 is arranged on the frame 100 and is located in front of the drying assembly 550 along the first direction. The receiving bag 650 is V-shaped. The plate that has been dried continues to move forward along the first direction, reaches the receiving bag 650, and is collected in the receiving bag 650. Generally, the receiving bag 650 is lower than the drying assembly 550, and an inclined guiding structure can also be arranged between the two to facilitate the plate to enter the receiving bag 650.
