Description

Technical Field

[0001] The utility model belongs to the technical field of screen printing, specifically a corner window ink suction knife. Background Technique

[0002] A corner window usually refers to a triangular sealed window located between the front door of a vehicle and the A-pillar and on the rear door.

[0003] Corner window printing is one of the key steps in the production process. Usually, an appropriate amount of ink is poured at one end of the screen printing plate, and a spreading ink plate is used to apply a certain pressure on the screen printing plate and move it towards the other end, so that the ink is distributed in the mesh holes of the pattern part. Then, the corner window is placed on the printing table, and the spreading ink plate is again used to apply pressure and move on the screen printing plate, so that the ink is extruded through the mesh holes of the graphic part onto the surface of the corner window, thus completing the corner window printing work.

[0004] For the production of some models of corner windows, full printing is required, and there should be no white edges after printing. When making the screen plate, it is larger than the pattern area. After printing, the ink at the edge cannot be transferred in time, resulting in the accumulation of ink at the edge of the printed product, which is likely to cause the problem that the ink overflows at the edge of the pattern and pollutes the non-printed area.

[0005] Therefore, the utility model provides a corner window ink suction knife. Content of the Utility Model

Specific embodiments

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Such as Figures 1 to 4As shown in the figure, the corner window ink suction knife of the embodiment of the present utility model includes a screen printing machine 8; a hydraulic cylinder 81 is installed in the middle of the screen printing machine 8; the output end of the hydraulic cylinder 81 is fixedly connected with a cross beam 82; an ink spreading knife 83 is installed at the bottom of the cross beam 82; two fixing plates 1 are fixedly connected to the end of the cross beam 82; an ink suction knife body 11 is installed in the middle of the fixing plate 1; a fixing frame 12 is fixedly connected to the top of the ink suction knife body 11; the fixing plate 1 is arranged in the middle of the fixing frame 12; a locking rod 13 is rotatably connected to the top of the fixing frame 12; a pressing plate 14 is rotatably connected to the end of the locking rod 13; an ink suction port 15 is opened at the end of the ink suction knife body 11; two ink suction pipes 16 are fixedly connected to the side wall of the ink suction knife body 11; during operation, the two ink suction knife bodies 11 are placed from one end of the fixing plate 1 through the fixing frame 12, so that the fixing plate 1 passes through the middle of the fixing frame 12, and the locking rod 13 is screwed to move downward on the top of the fixing frame 12. During the rotation of the locking rod 13, the ink suction knife body 11 is fixed in the middle of the fixing plate 1 through the pressing plate 14. When printing the corner window, the ink spreading knife 83 is installed at the bottom of the cross beam 82, one end of the ink suction pipe 16 is connected to a vacuum pipe, the screen printing machine 8 is powered on and started, the hydraulic cylinder 81 is controlled to make the output end move downward, and the ink suction knife body 11 runs simultaneously with the ink spreading knife 83. The ink spreading knife 83 and the end of the ink suction knife body 11 are attached to and move along the screen printing plate. The ink spreading knife 83 scrapes the ink from the surface of the printing plate, and at the same time as the ink spreading knife 83 scrapes the ink, the excess ink around the pattern is sucked away by vacuum, so as to achieve the purpose of transferring the ink. The ink suction knife body 11 can effectively suck away the ink at the edge of the printing screen pattern, effectively suck out the excess ink around the pattern area of the screen, can effectively reduce the operation of stopping the machine to wipe the excess ink during the printing process, thereby effectively improving the printing work efficiency, effectively reducing the accumulation of ink on the glass during the ink printing process, effectively reducing the overflow of ink at the pattern edge caused by the accumulation of ink on the glass and polluting the non-printing area, can effectively maintain the clarity of the printed pattern and the neatness of the edge, and effectively reduce the phenomenon of printing blurring or ghosting caused by ink accumulation.

[0026] As Figures 1 to 4As shown, a connecting plate 2 is fixedly connected to the side wall of the ink suction knife body 11; a sliding rod 21 is slidably connected to the middle of the connecting plate 2; a first spring 22 is fixedly connected to the end of the sliding rod 21; the first spring 22 is arranged outside the sliding rod 21; a buffer plate 23 is fixedly connected to the end of the sliding rod 21; during operation, when the cross beam 82 moves downward, first, it contacts the screen plate through the buffer plate 23. When the ink suction knife body 11 and the ink spreading knife 83 move downward continuously at the same time, when under pressure, the sliding rod 21 slides upward in the middle of the connecting plate 2, and the impact force when the ink spreading knife 83 and the ink suction knife body 11 contact the screen plate is absorbed through the buffer plate 23. When the printing is over, the sliding rod 21 is reset by the elastic stretching of the first spring 22. The cooperation of the sliding rod 21 and the first spring 22 can effectively reduce the direct impact of the ink suction knife body 11 on the screen plate, effectively reduce the wear and scratches of the ink suction knife body 11 and the screen plate caused by the direct impact, can effectively improve the service life of the screen plate and the ink suction knife body 11, and can effectively reduce the problem that the screen plate is deformed due to long-term impact force, and effectively maintain the accuracy and stability of the screen plate.

[0027] As Figures 2 to 6 As shown, a slide rail 3 is fixedly connected to the side wall of the ink suction knife body 11; the slide rail 3 is L-shaped; a slider 31 is slidably connected inside the slide rail 3; the end of the slider 31 is hinged to the slider 31; a support rod 32 is detachably installed at the end of the slider 31; during operation, after the ink suction knife body 11 sucks away the excess ink, the support rod 32 slides downward at one end of the slide rail 3 through the slider 31. A torsion spring is provided at the connection between the support rod 32 and the slider 31. When the support rod 32 slides downward from the side wall of the fixing plate 1, the support rod 32 without pressure rotates through the torsion spring, so that the thread brush 33 rotates to the position corresponding to the ink suction port 15 at the bottom of the ink suction knife body 11. Slide the support rod 32 horizontally inside the slide rail 3, and clean the position of the ink suction port 15 at the bottom of the ink suction knife body 11 through the thread brush 33. The thread brush 33 can effectively remove the ink residues attached to the position of the ink suction port 15, can clean the ink residues in time, effectively reduce the hardening of the ink residues accumulated at the bottom of the ink suction knife body 11 for a long time to form hard blocks, can effectively reduce the pollution of the screen plate or the printed matter during the subsequent printing process, and reduce the friction generated by the ink curing on the screen plate and the wear generated by the friction between the ink suction knife body 11 and the screen plate.

[0028] As Figures 2 to 6As shown, an elastic rod 4 is fixedly connected to the middle of the support rod 32; a magnetic block 41 is fixedly connected to the end of the elastic rod 4; a magnetic strip 42 is fixedly connected to the side wall of the ink absorbing knife body 11; the magnetic block 41 and the magnetic strip 42 attract each other when approaching; during operation, when the support rod 32 moves downward and rotates through the torsion spring, the magnetic block 41 and the magnetic strip 42 approach and attract each other, so that the support rod 32 maintains a stable position. When the support rod 32 slides, the magnetic block 41 slides in the middle of the magnetic strip 42 along with the support rod 32. When the screw brush 33 cleans the ink absorption port 15, during the process of sliding the support rod 32 back to its original position through the slider 31, when the support rod 32 is under the pressure of the side wall of the ink absorbing knife body 11, the support rod 32 rotates, so that the support rod 32 fits the side wall of the ink absorbing knife body 11. The attraction between the magnetic block 41 and the magnetic strip 42 when approaching can effectively increase the stability of the support rod 32 during the cleaning process of the screw brush 33, can effectively make the bristles of the screw brush 33 fully contact with the position of the ink absorption port 15 during the cleaning process, effectively improve the cleaning efficiency of the screw brush 33, and can effectively reduce the deviation generated during the cleaning process.

[0029] As Figures 2 to 4 shown, a scraping strip 5 is installed at the bottom of the buffer plate 23; the scraping strip 5 is fixedly connected to the bottom of the buffer plate 23; during operation, the sliding rod 21 is rotated inside the connecting plate 2, and the angle of the scraping strip 5 is adjusted through the sliding rod 21. When the ink absorbing knife body 11 moves downward, the bottom of the scraping strip 5 contacts the mesh plate. When the ink absorbing knife body 11 moves, the ink at the edge is scraped to the position of the ink absorption port 15 through the inclined angle of the scraping strip 5. By rotating the scraping strip 5 to change its angle, the ink at the edge of the ink can be scraped and guided to the position of the ink absorption port 15, so that the excess ink can be completely sucked in, effectively reducing the waste caused by ink residue. The ink at the printing edge can be scraped off in time and guided to the position of the ink absorption port 15, thereby effectively improving the efficiency of ink recycling.

[0030] As Figure 5 and Figure 6As shown, a first fixing block 6 is fixedly connected to the side wall of the support rod 32; a second spring 61 is fixedly connected to the side wall of the support rod 32; the end of the second spring 61 is fixedly connected to a second fixing block 62; the second fixing block 62 is arranged opposite to the first fixing block 6; during operation, when the thread brush 33 has been used for a long time, first press one end of the thread brush 33 towards the position of the second spring 61 to cause elastic contraction of the second spring 61. At this time, one end of the thread brush 33 disengages from the middle of the first fixing block 6, and then take out the other end of the thread brush 33 from the middle of the second fixing block 62. When installing a new thread brush 33, first place one end of the thread brush 33 in the middle of the second fixing block 62, then press the second spring 61 to make it contract, align the other end of the thread brush 33 with the position of the first fixing block 6, and when released, the first fixing block 6 and the second fixing block 62 fix the thread brush 33 through the elastic reset of the second spring 61, thereby disassembling and assembling the thread brush 33. Through the second spring 61, the thread brush 33 can be quickly installed. During the long-term use of the thread brush 33, wear is likely to occur. Quick installation and disassembly of the thread brush 33 can effectively reduce the replacement time, thereby effectively improving the overall work efficiency and reducing the need to disassemble the whole when the thread brush 33 needs to be replaced, thus reducing the replacement efficiency and cost of the thread brush 33.

[0031] As Figures 1 to 3 shown, a connecting pipe 7 is rotatably connected to the end of the ink suction pipe 16; a thread groove 71 is formed inside the connecting pipe 7; during operation, when the ink suction pipe 16 is connected to the vacuum pipeline, align one end of the connecting pipe 7 with one end of the vacuum pipeline, and twist the connecting pipe 7 to connect and fix it to the vacuum pipeline through the thread groove 71. At the same time, the connecting pipe 7 rotates at one end of the ink suction pipe 16. Through the connecting pipe 7, the ink suction pipe 16 can be quickly separated from the vacuum pipeline, enabling thorough cleaning and maintenance of the inside of the ink suction pipe 16 and the vacuum pipeline after long-term use, effectively reducing the problem of residual accumulation on the surface caused by the long-term passage of ink through the middle of the ink suction pipe 16, and effectively keeping the ink suction pipe 16 unobstructed during long-term use.

[0032] During operation, place the two ink suction knife bodies 11 through the fixing frame 12 from one end of the fixing plate 1, so that the fixing plate 1 passes through the middle of the fixing frame 12. Turn the locking rod 13 to move it downward on the top of the fixing frame 12. During the rotation of the locking rod 13, the ink suction knife body 11 is fixed in the middle of the fixing plate 1 through the pressing plate 14. When printing the corner window, install the ink spreading knife 83 at the bottom of the cross beam 82, connect one end of the ink suction pipe 16 to the vacuum pipe, power on the screen printing machine 8 and turn it on. Control the hydraulic cylinder 81 to make the output end move downward. The ink suction knife body 11 operates simultaneously with the ink spreading knife 83. The ink spreading knife 83 and the end of the ink suction knife body 11 are attached to and move along the screen printing plate. The ink spreading knife 83 scrapes the ink from the surface of the printing plate, and while the ink spreading knife 83 scrapes the ink, the excess ink around the pattern is sucked away by vacuum, thereby achieving the purpose of ink transfer. When the cross beam 82 moves downward, first, it contacts the screen plate through the buffer plate 23. When the ink suction knife body 11 continues to move downward simultaneously with the ink spreading knife 83, when under pressure, the sliding rod 21 slides upward in the middle of the connecting plate 2, and the buffer plate 23 absorbs the impact force when the ink spreading knife 83 and the ink suction knife body 11 contact the screen plate. When printing is completed, the sliding rod 21 is reset by the elastic stretching of the first spring 22. After the excess ink is sucked away by the ink suction knife body 11, slide the support rod 32 downward through the slider 31 at one end of the slide rail 3. A torsion spring is provided at the connection between the support rod 32 and the slider 31. When the support rod 32 slides downward from the side wall of the fixing plate 1, the support rod 32 without pressure rotates through the torsion spring, so that the thread brush 33 rotates to the position corresponding to the ink suction port 15 at the bottom of the ink suction knife body 11. Slide the support rod 32 horizontally inside the slide rail 3, and clean the position of the ink suction port 15 at the bottom of the ink suction knife body 11 through the thread brush 33. When the support rod 32 moves downward and rotates through the torsion spring, the magnetic block 41 and the magnetic strip 42 approach and attract each other, so that the support rod 32 maintains a stable position. When the support rod 32 slides, the magnetic block 41 slides in the middle of the magnetic strip 42 along with the support rod 32. When the thread brush 33 finishes cleaning the ink suction port 15, during the process of sliding the support rod 32 back to its original position through the slider 31, when the support rod 32 is under the pressure of the side wall of the ink suction knife body 11, the support rod 32 rotates, so that the support rod 32 fits the side wall of the ink suction knife body 11. Rotate the sliding rod 21 inside the connecting plate 2, and adjust the angle of the scraping strip 5 through the sliding rod 21. When the ink suction knife body 11 moves downward, the bottom of the scraping strip 5 contacts the screen plate. When the ink suction knife body 11 moves, the ink at the edge is scraped to the position of the ink suction port 15 through the inclined angle of the scraping strip 5. When the thread brush 33 has been used for a long time, first press one end of the thread brush 33 towards the position of the second spring 61, so that the second spring 61 undergoes elastic contraction. At this time, one end of the thread brush 33 disengages from the middle of the first fixing block 6, and then take out the other end of the thread brush 33 from the middle of the second fixing block 62. When installing a new thread brush 33, first place one end of the thread brush 33 in the middle of the second fixing block 62, and then press the second spring 61 to make it contract.Position the other end of the screw brush 33 corresponding to the first fixed block 6. When released, the first fixed block 6 and the second fixed block 62 fix the screw brush 33 through the elastic reset of the second spring 61, so as to disassemble and assemble the screw brush 33. When the ink suction tube 16 is connected to the vacuum pipeline, position one end of the connecting tube 7 corresponding to one end of the vacuum pipeline, and twist the connecting tube 7 to connect and fix it to the vacuum pipeline through the thread groove 71. At the same time, the connecting tube 7 rotates at one end of the ink suction tube 16.,
