Description

Technical Field

[0001] The invention relates to a cleaning device, in particular to a screen printing plate ink cleaning device. Background Art

[0002] The optical glass used in digital products will be printed with logos on the glass through the silk screen process during processing. After the ink is poured on the silk screen screen, the ink is scraped through the scraper and transferred to the glass surface through the silk screen mesh. Since the ink printed on the glass has a time limit, the time limit of the ink obtained by different raw material ratios is also different. Therefore, the ink cannot be used after the fixed time limit has exceeded, and the corresponding silk screen screen needs to be replaced. The ink remaining on the silk screen screen needs to be cleaned to avoid the residual ink and the new ink mixing together and affecting the use next time.

[0003] When cleaning the ink on the silk screen, as the ink decreases with use, some of the remaining ink will dry and form a membrane when not in use. The ink will adhere firmly to the mesh of the silk screen, and a brush cannot be used for cleaning, because using a brush to clean will easily move the warp and weft threads of the woven silk screen, causing the aperture of the mesh to change, thus increasing the difficulty of cleaning. Summary of the invention

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0028] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] The present invention specifically discloses a screen printing plate ink cleaning device, such as Figure 1-Figure 9As shown, it includes: a support frame 11, which is a rectangular container with an open top, and a support angle plate 12 is symmetrically fixedly installed around the support frame 11. The top of the support angle plate 12 has a downward groove, and the four top corners of the screen printing screen 200 are correspondingly placed in the groove, so as to set up the screen printing screen 200 that needs to be cleaned. Linear guide rails 13 are fixedly installed on both sides of the support frame 11, and a moving block 14 is driven and installed on the linear guide rail 13. The moving block 14 is driven by the linear guide rail 13 to achieve transverse movement, and a guide frame 15 is fixedly installed on the moving block 14. The two moving blocks 14 are connected to the first spray mechanism. At this time, after the silk screen screen 200 to be cleaned is placed on the support corner plate 12, the first spray mechanism is fitted with the bottom of the silk screen screen 200. After the first spray mechanism starts spraying, the linear guide 13 drives the moving block 14 to move with the first spray mechanism, so as to gradually spray the bottom of the silk screen screen 200, and the ink remaining at the bottom will fall down after spraying. A pulley block 21 is slidably mounted on the guide frame 15, and the pulley block 21 can slide in the up and down directions on the guide frame 15. A mounting plate 23 is fixedly connected to the pulley block 21. Both sides of the trapezoidal cover 34 are connected to the mounting plate 23, so that the trapezoidal cover 34 is erected above the first spray mechanism. Steam nozzles 35 are evenly installed in the trapezoidal cover 34. After the air pipe 36 is connected to the steam nozzle 35, steam enters through the air pipe 36 and is then sprayed out from the steam nozzle 35. The opening of the trapezoidal cover 34 faces the silk screen screen 200 below, so that the sprayed steam will rush to the surface of the silk screen screen 200.

[0030] When in use, the trapezoidal cover 34 is pulled upward, and then the screen printing screen 200 is placed on the support corner plate 12 so that it is between the trapezoidal cover 34 and the first spray mechanism. The first spray mechanism and the trapezoidal cover 34 move along the surface of the screen printing screen 200 following the movement of the moving block 14. The steam nozzle 35 above the screen printing screen 200 sprays steam downward, and the ink attached to the mesh will fall off by itself under the flushing of the hot steam. At the same time, the first spray mechanism at the bottom of the screen printing screen 200 sprays from bottom to top, so that the ink penetrating from the top to the bottom can be flushed and dispersed. At this time, the ink will not adhere to the mesh and will eventually fall off from the screen printing screen 200. At this point, the stubborn ink attached to the screen printing screen 200 can be effectively and simply cleaned. When the main attached difficult-to-clean ink is cleaned, the screen printing screen 200 is sent to the immersion tank for rinsing and then taken out and put into production again.

[0031] Among them, the hot steam sprayed by the steam nozzle 35 in the trapezoidal cover 34 will only gather in the trapezoidal cover 34 under the constraint of the trapezoidal cover 34, and spray out from the outlet in a fixed direction. The formed steam flow will not be lost, so the temperature in the steam will not drop rapidly, and more heat can be transferred to the attached ink and silk screen plate 200. The heated ink helps the ink to detach from the mesh.

[0032] according to Figure 2 and Figure 8 As shown, the first spray mechanism includes: a mounting box 31 connected to the moving block 14, the box opening of the mounting box 31 can be attached to the surface of the screen printing screen 200, the tube 32 is connected to the inside of the mounting box 31 from the outside, and a plurality of spray heads 33 are evenly spaced in the mounting box 31 and connected to the tube 32. When in use, the box opening of the mounting box 31 is attached to the surface of the screen printing screen 200, the spray head 33 sprays the screen printing screen 200, and under the constraint of the mounting box 31, the water flow sprayed by the spray head 33 is constrained within the box opening range, so that the spray water flow is more concentrated and will not splash around, and it can also save water for cleaning. After being sprayed, the ink falls downward and finally falls into the mounting box 31. The bottom of the mounting box 31 is provided with a discharge port to allow waste liquid to be discharged.

[0033] according to Figure 6 and Figure 7 As shown, it also includes: a thermal insulation sleeve 41 wrapped around the air pipe 36. Since steam passes through the air pipe 36, the thermal insulation sleeve 41 can wrap the exposed air pipe 36 to avoid burns caused by the air pipe 36.

[0034] according to Figure 4 and Figure 5 As shown, it also includes: a second spray mechanism 61 having the same structure as the first spray mechanism, the second spray mechanism 61 is installed on the mounting plate 23, and the mounting plate 23 and the pulley block 21 are connected by a rotating middle piece 51, so that the mounting plate 23 can be rotated by the rotating middle piece 51. Specifically, when in use, after the steam nozzle passes along the surface of the screen printing screen 200, the mounting plate 23 can be rotated, so that the second spray mechanism 61 can face the screen printing screen 200 below after the mounting plate 23 rotates half a circle, and then the upper surface of the screen printing screen 200 is sprayed and cleaned by the second spray mechanism 61, so as to dilute and mix the large pieces of ink remaining on the screen printing screen 200 to prevent the ink from adhering to the conjunctiva again.

[0035] according to Figure 5 and Fig. 9As shown, the rotating middle piece 51 includes: a rotating shaft 511 divided into two sections that can rotate with each other, and the two sections of the rotating shaft 511 that can rotate with each other are respectively installed with a fixed block 512, one of the fixed blocks 512 is symmetrically provided with through holes, a spring 513 is placed in the through hole, a top ball 514 is placed in the through hole, the top ball 514 is kept in a pop-up state by the spring 513, a cover plate 515 is installed on the fixed block 512 to prevent the top ball 514 from popping out from the through hole, and a matching groove 516 matching the top ball 514 is opened on the fixed block 512 on the other side opposite to the top ball 514. Specifically, under normal conditions, the top bead 514 is pressed against the fitting groove 516 by the spring 513, so as to prevent the two fixed blocks 512 from rotating easily. Due to the existence of the top bead 514 and the fitting groove 516, when the mounting plate 23 is rotated, the top bead 514 is disengaged from the fitting groove 516, and after rotating half a circle, the top bead 514 can be re-engaged in the fitting groove 516. At this time, the trapezoidal hood 34 and the second spray mechanism 61 just exchange the upper and lower positions.

[0036] according to Figure 5 and Fig. 9 As shown, it also includes: a slider 517 is slidably connected to one of the fixed blocks 512, and a slot 518 is opened on the other fixed block 512 at a position corresponding to the slider 517, allowing the slider 517 to enter. After the slider 517 slides into the slot 518, the two fixed blocks 512 are stuck to each other by the slider 517 and cannot rotate. When it is necessary to rotate, it is only necessary to push the slider 517 out of the slot 518. Therefore, in use, in order to prevent the mounting plate 23 from deflecting by itself, the fixed block 512 can be locked by the slider 517.

[0037] according to Figure 8 As shown, it also includes: a partition plate 72 fixedly arranged on a side wall of one side of the interior of the installation box 31, with a gap left between the partition plate 72 and the side wall, so as to form an independent cavity inside the installation box 31, and an exhaust duct 71 is installed on the outside of the installation box 31, and the exhaust duct 71 is connected to the independent cavity. After the box mouth of the installation box 31 is attached to the silk screen stencil 200, the cavity mouth of the independent cavity is also attached to the silk screen stencil 200, and after the attachment, it is sucked outward through the exhaust duct 71. At this time, in conjunction with the spraying of the spray head 33, the ink after spraying will enter the independent cavity under the suction of the exhaust duct 71, and be discharged from the exhaust duct 71, so that the large blocks of ink adhering or hanging on the surface are peeled off from the silk screen stencil 200 by suction and collected.

[0038] according to Figure 8As shown, it also includes: rotating a rotating rod 73 arranged at the end of the cavity mouth of the independent cavity. When the independent cavity moves together with the installation box 31, the rotating rod 73 is attached to the surface of the silk screen stencil 200 and rotates accordingly. The purpose of setting the rotating rod 73 is that during the independent cavity following the movement, the straight edge of the end is pressed against the silk screen stencil 200 to scrape away the ink adhered to the silk screen stencil 200, and the ink is piled up together, so that it cannot enter the independent cavity. Therefore, after the rotating rod 73 is rotatably installed at the end of the independent cavity, the rotating rotating rod 73 will not scrape away the ink during the movement of the independent cavity, and the ink can enter the independent cavity.

[0039] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
