Description

Technical Field

[0001] The invention relates to the technical field of screen printing machines, in particular to an ink scraper device for a screen printing machine. Background Art

[0002] During printing, a screen printer places the substrate on the printing platform. Printing is performed based on the principle that the mesh holes in the image area of the screen printing plate allow ink to pass through, while the mesh holes in the non-image area do not. Ink is poured onto one end of the screen printing plate, and a squeegee applies pressure to the inked portion of the screen while moving toward the other end. As the squeegee moves, the ink is squeezed through the mesh holes in the image area onto the substrate.

[0003] For example, an automatic temperature control transformer with announcement number CN216733457U can adjust the angle of the scraper through the rotating component, thereby adjusting the scraping angle of the printing, avoiding the need to replace tools with different angles, and improving the convenience of use; at the same time, the cleaning component has the function of cleaning the scraper, which can effectively remove the material on the surface of the scraper, making cleaning and maintenance convenient. When the ink scraper is scraping ink, a certain amount of ink will adhere to the scraper. If the ink is not cleaned in time, the ink will adhere to the scraper after condensation, affecting the accuracy of the subsequent use of the scraper, and the condensation of the ink will increase the difficulty of cleaning. If the ink is cleaned directly, although the scraper can be cleaned, it will not be easy to remove. Cleaning: During the cleaning process of the scraper, the scraper needs to be stopped, which will take up printing time, make continuous processing impossible, and have low work efficiency. In addition, the scraper is prone to causing ink dripping during the cleaning process. If the scraper is cleaned during the reset movement, although the scraper does not need to scrape and squeeze the ink during the reset movement, it can save a certain amount of use time. However, the ink is prone to dripping during the reset movement of the scraper. If the ink drips during the reset movement of the scraper, it is inconvenient to place the printed carrier subsequently, which will affect the printing quality of the subsequent printed carrier. If the scraper is not cleaned during the reset movement, the ink attached to the scraper may still drip, and there are certain defects in use.

[0004] Therefore we propose an ink scraper device for a screen printing machine, in order to solve the above problems. Summary of the Invention

[0028] By adopting the above technical solution, the movement of the push plate can drive the adjustment plate to rotate.

[0029] Compared with the prior art, the present invention has the following beneficial effects: the ink scraper device for a screen printing machine can automatically clean the scraper body after the scraper body is reset after use, so that the two scraper bodies can be used intermittently, reducing the wear of the two scraper bodies and prolonging the service life. In addition, the scraper body can avoid ink dripping during the cleaning process to avoid affecting subsequent printing work, and can avoid stopping the machine for cleaning, facilitating continuous printing work and improving practicality.

[0030] 1. The movable frame is set on the screen printing machine. The movable frame can move back and forth so that the scraper body can scrape the ink. When the scraper body needs to be reset after moving, the rotating plate is rotated a quarter of a turn between the two adjustment plates. During the rotation of the rotating plate, the two sets of L-shaped frames below rotate in a circle. After the subsequent movable frame moves and resets, the rotating plate is continued to rotate a quarter of a turn. At this time, when the L-shaped frame rotates to the top, it can abut against the mounting seat. Then the rotating plate continues to rotate the roller on the bottom surface of the mounting seat. Since the bottom edge of the mounting seat is parallel to the mounting frame, the L-shaped frame can move downward during the circular rotation, which can drive the connecting plate and the movable seat to move. After the movable seat moves, it can be pushed to move by the sliding connection between the column and the movable groove on the movable seat. When the movable plate is moved away from the mounting bracket, the elastic coefficient of the elastic spring will not be too small to prevent the movable plate from moving accidentally. After the positioning rod moves, it can be disengaged from the positioning slot on the mounting bracket, so that the mounting bracket loses its limit. When the lower mounting bracket rotates to the upper side, the mounting bracket loses its limit and drives the scraper body downward under the action of gravity, so that the mounting bracket slides in the connecting slot. After the scraper body moves downward, the two rubber scrapers can scrape the two ends of the scraper body, and the torsion spring on the support bracket is in a stretched state, so that the two rubber scrapers are always in contact with the scraper body. Ink can be gathered on the top of the rubber scraper during the cleaning process of the rubber scraper. After the cleaning is completed, the rubber scraper is tilted. The ink that has been cleaned can enter the temporary storage box, and then the movable frame is reset and moved. The ink attached to the scraper body that has just been used can be automatically cleaned and ink dripping can be avoided. Before the movable frame is reset, the rotating plate is rotated a quarter of a turn. At this time, the scraper body that has just been used has not been cleaned yet, but the scraper body is in a horizontal state and the ink will not drip easily. The scraper body used last time is rotated a quarter of a turn, and the ink remaining in the temporary storage box last time will not drip easily. After the movable frame is reset, the rotating plate is further rotated a quarter of a turn, so that the scraper body used last time is rotated to the bottom, and the scraper body moves under the action of gravity, so that the mounting frame moves down in the connecting groove. After the mounting frame moves, the positioning rod is aligned with the positioning groove, and the positioning rod is moved under the action of the telescopic spring. Insert the positioning slot to position the mounting bracket. At this time, the scraper body after cleaning can be used to scrape and squeeze ink, and the scraper body that has just been used is cleaned on the top. The ink cleaned on the two rubber scrapers can slowly flow into the temporary storage box above during this printing process, so that the scraper body can be automatically cleaned after it is reset and moved after use. When the scraper body is used to scrape ink again, the ink temporarily stored in the temporary storage box can flow back to the tip of the scraper body, and the temporarily stored ink can be reused. The two scraper bodies are rotated and used intermittently, and the two scraper bodies are not straight up and down. After the tip of the scraper body is cleaned, the cleaned ink can be temporarily stored, so that when the scraper body is not scraping and squeezing ink,It can prevent the cleaned ink from flowing to the tip of the scraper body under the action of gravity, and can prevent the tip of the scraper body from adhering to ink when scraping ink again. If there is ink adhering to the tip of the scraper body when scraping ink, the ink adhering to the tip will affect the uniformity of the scraping and squeezing printing during the initial scraping and squeezing work, thereby improving the work quality. It can enable the two scraper bodies to be used intermittently, reducing the wear of the two scraper bodies and extending the service life. In addition, the scraper body can prevent ink from dripping during the cleaning process, thereby avoiding affecting the subsequent printing work, avoiding stopping for cleaning, facilitating continuous printing work, and improving practicality.

[0031] 2. When the scraper body needs to be replaced, unscrew the two sets of positioning bolts so that the baffle can lose its limit, and then the baffle can be rotated so that the positioning plate no longer abuts the scraper body, and the scraper body can be pulled out horizontally to separate the mounting strip from the mounting slot, and the scraper body can be disassembled. When installing the scraper body, insert the mounting strip into the mounting slot, and then rotate the baffle to position the scraper body, and then screw in the positioning bolts to position the baffle to complete the installation of the scraper body, thereby facilitating the disassembly and assembly of the scraper body and the replacement of the scraper body, thereby improving practicality.

[0032] 3. When it is necessary to control the rotation of the rotating plate, the driving motor can drive the rotating rod to rotate, so that the rotating plate rotates. When the scraper body is in use, when printing different types of printing carriers, the hydraulic push rod can be started to drive the push plate to move, and then the worm can be driven to rotate by the engagement of the tooth plate and the rotating gear. The worm can drive the worm wheel to rotate, and then the rotating shaft can be driven to rotate, so that the adjustment plate is rotated, so that the inclination angle of the scraper body can be adjusted, which is convenient for fine-tuning the angle of the scraper body, and an inclination sensor can be set on the adjustment plate to improve the adjustment accuracy, thereby facilitating the adjustment of the angle of the scraper body and improving the applicability of printing.

[0049] A rotating shaft 105 is rotatably connected to the lower side of the two fixed plates 104 on the adjacent side, and a rotating frame 106 is fixedly installed on the adjacent end of the two rotating shafts 105. An adjustment plate 107 is fixedly installed on the adjacent end of the two rotating frames 106. At the same time, a rotating rod 108 is rotatably connected to the lower side between the two adjustment plates 107, and the adjacent ends of the two rotating rods 108 are fixedly connected to the rotating plate 109. The rotating plate 109 has symmetrical connecting grooves 110 formed inside.

[0050] One side of the two sets of rubber scrapers 206 abuts against the two scraper bodies 202 respectively, and a temporary storage box 208 is fixedly installed on one side of the rubber scrapers 206. Two sets of sliding grooves 209 are symmetrically opened on one side of the two connecting grooves 110 inside the rotating plate 109. At the same time, the sliding grooves 209 are slidably connected to the inner part of the limit rods 2091, and the two sets of limit rods 2091 are fixedly connected to the two mounting frames 201 respectively.

[0051] Inside the rotating plate 109, positioning rods 211 are slidably connected to both sides of the two mounting frames 201, and two sets of movable plates 210 are fixedly installed on the ends of the two sets of positioning rods 211 away from the mounting frames 201, and telescopic springs 212 are sleeved on one side of the outside of the two sets of positioning rods 211. At the same time, the two ends of the telescopic springs 212 are fixedly connected to the rotating plate 109 and the movable plate 210 respectively. In addition, positioning grooves 213 are symmetrically opened on both sides of the two mounting frames 201, and the positioning rods 211 are plugged into the positioning grooves 213. A ball bearing 214 is hinged on the end of the positioning rods 211 away from the movable plate 210.

[0052] The movable plate 210 is symmetrically mounted on both sides of the two positioning rods 211 with movable seats 215, and the rotating plate 109 is fixedly mounted on one side of the two movable seats 215 with a limit frame 217, and the inner portion of the limit frame 217 is slidably connected to a connecting plate 218, while one end of the connecting plate 218 is fixedly mounted with a U-shaped frame 219, and the inner side of the U-shaped frame 219 is fixedly mounted with a column 220, and a movable groove 216 is opened through one side of the movable seat 215, and the column 220 is slidably connected to the movable groove 216;

[0053] An L-shaped frame 221 is fixedly installed on one side of the U-shaped frame 219, and a fixing seat 222 is fixedly installed on the end of the L-shaped frame 221 away from the U-shaped frame 219, and a roller 223 is rotatably connected inside the fixing seat 222. At the same time, mounting seats 224 are symmetrically installed above the side where the two adjustment plates 107 are close to each other, and the two rollers 223 above are in contact with the mounting seats 224.

[0054] Example 1: Figure 1-Figure 7As shown, the movable frame 1 is arranged on the screen printing machine, and the movable frame 1 can move back and forth so that the scraper body 202 scrapes and squeezes the ink. When the scraper body 202 needs to be reset after moving, the rotating plate 109 rotates a quarter of a turn between the two adjustment plates 107. During the rotation of the rotating plate 109, the two groups of L-shaped frames 221 below rotate in a circle. After the subsequent movable frame 1 moves and resets, the rotating plate 109 continues to rotate a quarter of a turn. At this time, when the L-shaped frame 221 rotates to the top, it can abut against the mounting seat 224. Then the rotating plate 109 continues to rotate the roller 223 to rotate on the bottom surface of the mounting seat 224. Since the bottom edge of the mounting seat 224 is parallel to the mounting frame 201, the L-shaped frame 221 can move downward during the circular rotation. The movable seat 215 can be pushed to move by the sliding connection between the column 220 and the movable groove 216 on the movable seat 215, thereby pushing the movable plate 210 away from the mounting bracket 201. After the movable plate 210 moves, the telescopic spring 212 can be stretched and the positioning rod 211 can be driven to move. The elastic coefficient of the telescopic spring 212 is not too small to prevent the movable plate 210 from moving accidentally. After the positioning rod 211 moves, it can be disengaged from the positioning groove 213 on the mounting bracket 201, so that the mounting bracket 201 loses its limit. When the lower mounting bracket 201 rotates to the upper side, the mounting bracket 201 loses its limit and drives the scraper body 202 to move downward under the action of gravity, so that The mounting frame 201 slides in the connecting groove 110, and after the scraper body 202 moves down, the two rubber scrapers 206 can scrape the two sides of the scraper body 202, and the torsion spring 207 on the supporting frame 205 is in a stretched state, so that the two rubber scrapers 206 are always in contact with the scraper body 202. During the cleaning process of the rubber scraper 206, the ink can be gathered on the top of the rubber scraper 206. After the cleaning is completed, the rubber scraper 206 is tilted so that the cleaned ink can enter the temporary storage box 208, and then the movable frame 1 is reset and moved. The ink attached to the scraper body 202 that has just been used can be automatically cleaned and ink dripping can be avoided. Before the movable frame 1 is reset, the rotating plate 109 rotates a quarter of a turn. At this time, the scraper body 202 that has just been used 02 has not been cleaned yet, but the scraper body 202 is in a horizontal state and the ink will not drip easily. The scraper body 202 used last time rotates a quarter of a turn, and the ink remaining in the temporary storage box 208 last time will not drip easily. After that, the movable frame 1 is reset to make the rotating plate 109 continue to rotate a quarter of a turn, so that the scraper body 202 used last time rotates to the bottom, and the scraper body 202 moves under the action of gravity, so that the mounting frame 201 moves down in the connecting groove 110. After the mounting frame 201 moves, the positioning rod 211 is aligned with the positioning groove 213. Under the action of the telescopic spring 212, the positioning rod 211 is inserted into the positioning groove 213 to position the mounting frame 201. At this time, the cleaned scraper body 202 can be used to scrape and squeeze ink.The scraper body 202 that has just been used is cleaned at the top, and the ink cleaned on the two rubber scrapers 206 can slowly flow into the upper temporary storage box 208 during this printing process, so that the scraper body 202 can be automatically cleaned after it is reset and moved after use. When the scraper body 202 is used to scrape ink again, the ink temporarily stored in the temporary storage box 208 can flow back to the tip of the scraper body 202, and the temporarily stored ink can be reused. The two scraper bodies 202 are rotated and used intermittently. The two scraper bodies 202 are not straight up and down. After the tip of the scraper body 202 is cleaned, the cleaned ink can be temporarily stored, so that the scraper When the main body 202 is not scraping ink, it can prevent the cleaned ink from flowing to the tip of the scraper body 202 under the action of gravity. It can also prevent the tip of the scraper body 202 from adhering to the ink when the scraper body 202 is scraping ink again. If there is ink adhering to the tip of the scraper body 202 when scraping ink, the ink adhering to the tip will affect the uniformity of the scraping and squeezing printing during the initial scraping and squeezing work, thereby improving the work quality. It can enable the two scraper bodies 202 to be used intermittently, reducing the wear of the two scraper bodies 202 and extending the service life. In addition, the scraper body 202 can prevent ink from dripping during the cleaning process to avoid affecting subsequent printing work, avoiding stopping for cleaning, facilitating continuous printing work, and improving practicality.

[0057] Example 2: Figure 7 and Figure 8As shown, when the scraper body 202 needs to be replaced, the two sets of positioning bolts 305 are unscrewed so that the baffle 302 can lose its limit, and then the baffle 302 can be rotated so that the positioning plate 303 no longer abuts the scraper body 202, and the scraper body 202 can be pulled out horizontally to separate the mounting strip 204 from the mounting groove 203, and the scraper body 202 can be disassembled. When installing the scraper body 202, the mounting strip 204 is inserted into the mounting groove 203, and then the baffle 302 is rotated to position the scraper body 202, and then the positioning bolts 305 are screwed in to position the baffle 302, completing the installation of the scraper body 202, thereby facilitating the disassembly and assembly of the scraper body 202, and facilitating the replacement of the scraper body 202, thereby improving practicality.

At the same time, a support block 403 is symmetrically mounted on one side of the left fixed plate 104 above the worm gear 402. A worm 404 is rotatably connected between the two support blocks 403, and the worm 404 is meshed with the worm gear 402.

[0060] A hydraulic push rod 406 is fixedly installed on the front of the left fixed plate 104, and a push plate 407 is fixedly installed on the movable end of the hydraulic push rod 406, and one end of the worm 404 passes through a side support block 403 and is fixedly installed with a rotating gear 405, and at the same time, a tooth plate 408 is fixedly installed on one side of the push plate 407, and the rotating gear 405 is meshed with the tooth plate 408, and a guide rod 409 is fixedly installed on the bottom of the push plate 407, and a guide frame 410 is slid on the outer side of the guide rod 409, and the guide frame 410 is fixedly connected to the fixed plate 104.

[0061] Example 3: Figure 1 and Figure 9As shown, when it is necessary to control the rotation of the rotating plate 109, the driving motor 401 can drive the rotating rod 108 to rotate, so that the rotating plate 109 rotates. When the scraper body 202 is in use, when printing different types of printing carriers, the hydraulic push rod 406 can be started to drive the push plate 407 to move, and then the tooth plate 408 can be engaged with the rotating gear 405 to drive the worm 404 to rotate. The worm 404 can drive the worm wheel 402 to rotate, and then drive the rotating shaft 105 to rotate, so that the adjustment plate 107 rotates, so that the inclination angle of the scraper body 202 can be adjusted, which is convenient for fine-tuning the angle of the scraper body 202, and an inclination sensor can be set on the adjustment plate 107 to improve the adjustment accuracy, thereby facilitating the adjustment of the angle of the scraper body 202 and improving the applicability of printing.

[0062] Working principle: When using the ink scraper device for screen printing machine, first, according to Figures 1-9As shown, the movable frame 1 is arranged on the screen printing machine, and the movable frame 1 can move back and forth so that the scraper body 202 scrapes and squeezes the ink. When the scraper body 202 needs to be reset after moving, the rotating plate 109 rotates a quarter of a turn between the two adjustment plates 107. During the rotation of the rotating plate 109, the two groups of L-shaped frames 221 below rotate in a circle. After the subsequent movable frame 1 moves and resets, the rotating plate 109 continues to rotate a quarter of a turn. At this time, when the L-shaped frame 221 rotates to the top, it can abut against the mounting seat 224. Then the rotating plate 109 continues to rotate the roller 223 to rotate on the bottom surface of the mounting seat 224. Since the bottom edge of the mounting seat 224 is parallel to the mounting frame 201, the L-shaped frame 221 can move downward during the circular rotation. The movable seat 215 can be pushed to move by the sliding connection between the column 220 and the movable groove 216 on the movable seat 215, thereby pushing the movable plate 210 away from the mounting bracket 201. After the movable plate 210 moves, the telescopic spring 212 can be stretched and the positioning rod 211 can be driven to move. The elastic coefficient of the telescopic spring 212 is not too small to prevent the movable plate 210 from moving accidentally. After the positioning rod 211 moves, it can be disengaged from the positioning groove 213 on the mounting bracket 201, so that the mounting bracket 201 loses its limit. When the lower mounting bracket 201 rotates to the upper side, the mounting bracket 201 loses its limit and drives the scraper body 202 to move downward under the action of gravity, so that The mounting frame 201 slides in the connecting groove 110, and after the scraper body 202 moves down, the two rubber scrapers 206 can scrape the two sides of the scraper body 202, and the torsion spring 207 on the supporting frame 205 is in a stretched state, so that the two rubber scrapers 206 are always in contact with the scraper body 202. During the cleaning process of the rubber scraper 206, the ink can be gathered on the top of the rubber scraper 206. After the cleaning is completed, the rubber scraper 206 is tilted so that the cleaned ink can enter the temporary storage box 208, and then the movable frame 1 is reset and moved. The ink attached to the scraper body 202 that has just been used can be automatically cleaned and ink dripping can be avoided. Before the movable frame 1 is reset, the rotating plate 109 rotates a quarter of a turn. At this time, the scraper body 202 that has just been used 02 has not been cleaned yet, but the scraper body 202 is in a horizontal state and the ink will not drip easily. The scraper body 202 used last time rotates a quarter of a turn, and the ink remaining in the temporary storage box 208 last time will not drip easily. After that, the movable frame 1 is reset to make the rotating plate 109 continue to rotate a quarter of a turn, so that the scraper body 202 used last time rotates to the bottom, and the scraper body 202 moves under the action of gravity, so that the mounting frame 201 moves down in the connecting groove 110. After the mounting frame 201 moves, the positioning rod 211 is aligned with the positioning groove 213. Under the action of the telescopic spring 212, the positioning rod 211 is inserted into the positioning groove 213 to position the mounting frame 201. At this time, the cleaned scraper body 202 can be used to scrape and squeeze ink.The scraper body 202 that has just been used is cleaned at the top, and the ink cleaned on the two rubber scrapers 206 can slowly flow into the temporary storage box 208 at the top during the current printing process;

[0063] When the scraper body 202 needs to be replaced, the two sets of positioning bolts 305 are unscrewed so that the baffle 302 can lose its limit, and then the baffle 302 can be rotated so that the positioning plate 303 no longer abuts the scraper body 202, and the scraper body 202 can be pulled out horizontally to separate the mounting strip 204 from the mounting slot 203, so that the scraper body 202 can be disassembled. When the scraper body 202 is installed, the mounting strip 204 is inserted into the mounting slot 203, and then the baffle 302 is rotated to position the scraper body 202, and then the positioning bolts 305 are screwed in to position the baffle 302, and the installation of the scraper body 202 is completed. When it is necessary to control the rotation of the rotating plate 109, the driving The motor 401 can drive the rotating rod 108 to rotate, so that the rotating plate 109 rotates. When the scraper body 202 is in use, when printing different types of printing carriers, the hydraulic push rod 406 can be started to drive the push plate 407 to move, and then the tooth plate 408 can be engaged with the rotating gear 405 to drive the worm 404 to rotate. The worm 404 can drive the worm wheel 402 to rotate, and then drive the rotating shaft 105 to rotate, so that the adjustment plate 107 rotates, so that the inclination angle of the scraper body 202 can be adjusted, which is convenient for fine-tuning the angle of the scraper body 202, and an inclination sensor can be set on the adjustment plate 107 to improve the adjustment accuracy.
