Description

Technical Field

[0001] The present invention relates to a cleaning device, and more particularly to an ink cleaning device for a silk screen printing plate. Background Art

[0002] When processing optical glass used in digital products, markings are printed on the glass through a silk screen printing process. After the ink is poured on the silk screen printing plate, the ink is scraped by a squeegee, and the ink passes through the silk screen holes and is transferred to the glass surface. Since the ink printed on the glass has a shelf life, and the shelf life of inks obtained with different raw material ratios is also different, the ink cannot be used continuously after exceeding the fixed shelf life. Accordingly, the corresponding silk screen printing plate also needs to be replaced. Among them, the ink remaining on the silk screen printing plate needs to be cleaned up to avoid the residual ink mixing with the new ink during the next use and affecting the use.

[0003] When cleaning the ink on the silk screen printing plate, as the ink decreases with use, some of the remaining ink will dry and form a film without being used, and the ink will firmly adhere to the mesh holes of the silk screen. A brush cannot be used during cleaning because using a brush to clean easily causes the warp and weft threads of the woven silk screen to move, resulting in a change in the aperture of the mesh holes. Therefore, the cleaning difficulty will increase during cleaning. Summary of the Invention

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. Additionally, it should be noted that, for the sake of description, only the parts related to the present application rather than all the structures are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "mounted", "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 a connection that can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0030] The present invention specifically discloses a silk - screen printing plate ink cleaning device, as Figures 1 - 9As shown in the figure, it includes: a support frame 11, which is a rectangular container with an open top. On the inner periphery of the support frame 11, object-supporting angle plates 12 are symmetrically and fixedly installed. A downward groove is formed at the top of the object-supporting angle plate 12. The four top corners of the silk screen printing plate 200 are correspondingly placed in the grooves, thereby lifting the silk screen printing plate 200 to be cleaned. On both sides inside the support frame 11, linear guide rails 13 are fixedly installed. A moving block 14 is drivingly installed on the linear guide rails 13. The moving block 14 realizes lateral movement through the drive of the linear guide rails 13. A guiding frame 15 is fixedly installed on the moving block 14. The two moving blocks 14 are jointly connected to the first spraying mechanism. At this time, after the silk screen printing plate 200 to be cleaned is placed on the object-supporting angle plate 12, the first spraying mechanism is attached to the bottom of the silk screen printing plate 200. After the first spraying mechanism starts spraying, the linear guide rails 13 drive the moving block 14 to drive the first spraying mechanism to move, thereby gradually spraying the bottom of the silk screen printing plate 200, and the residual ink at the bottom will fall downward after spraying. A pulley block 21 is slidably installed on the guiding frame 15. The pulley block 21 can slide in the up and down directions on the guiding 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, thereby erecting the trapezoidal cover 34 above the first spraying mechanism. Steam nozzles 35 are evenly installed at intervals in the trapezoidal cover 34. After the air pipe 36 is communicated with the steam nozzles 35, steam enters through the air pipe 36 and then sprays out from the steam nozzles 35. The trapezoidal cover 34 is opened towards the silk screen printing plate 200 below, so that the sprayed steam will rush onto the surface of the silk screen printing plate 200.

[0031] During use, the trapezoidal cover 34 is pulled upward, and then the silk screen printing plate 200 is placed on the object-supporting angle plate 12 so that it is between the trapezoidal cover 34 and the first spraying mechanism. The first spraying mechanism and the trapezoidal cover 34 move along the surface of the silk screen printing plate 200 following the movement of the moving block 14. The steam nozzles 35 above the silk screen printing plate 200 spray steam downward. The ink adhering to the mesh holes will fall off automatically under the scouring of the hot steam. At the same time, in cooperation with the first spraying mechanism at the bottom of the silk screen printing plate 200 spraying from bottom to top, the ink infiltrating from top to bottom can be scoured and dispersed. At this time, the ink will not adhere to the mesh holes and will finally separate from the silk screen printing plate 200. Thus, the stubborn ink adhering to the silk screen printing plate 200 can be effectively and simply cleaned. After the mainly difficult-to-clean ink is cleaned, the silk screen printing plate 200 is sent into the soaking pool for rinsing and then taken out and can be put into production use again.

[0032] Among them, the hot steam ejected by the steam nozzle 35 inside the trapezoidal cover 34 will be gathered only in the trapezoidal cover 34 under the constraint of the trapezoidal cover 34 and ejected from the outlet in a fixed direction. The formed steam flow will not disperse and be lost, so that the temperature in the steam will not rapidly decrease, and more heat can be transferred to the attached ink and the screen printing stencil 200. After heating, the ink helps the ink to break away from the mesh holes.

[0033] According to Figure 2 and Figure 8 As shown, the first spraying mechanism includes: an installation box 31 connected to the moving block 14. The box opening part of the installation box 31 can be attached to the surface of the screen printing stencil 200. A pipe 32 is connected from the outside to the inside of the installation box 31. A plurality of spray heads 33 are evenly spaced in the installation box 31 and communicated with the pipe 32. During use, the box opening part of the installation box 31 is attached to the surface of the screen printing stencil 200, and the spray heads 33 spray water towards the screen printing stencil 200. Under the constraint of the installation box 31, the water flow ejected by the spray heads 33 is constrained within the range of the box opening, so that the spraying water flow is more concentrated and will not splash around. At the same time, it can also save cleaning water. After being sprayed, the ink drops downward and finally falls into the installation box 31. The bottom of the installation box 31 is provided with a discharge port for allowing waste liquid to be discharged.

[0034] According to Figure 6 and Figure 7 As shown, it further includes: a heat insulation sleeve 41 wrapped around the air pipe 36. Since the steam passes through the air pipe 36, the exposed air pipe 36 can be wrapped by the heat insulation sleeve 41 to avoid being scalded by the air pipe 36.

[0035] According to Figure 4 and Figure 5 As shown, it further includes: a second spraying mechanism 61 having the same structure as the first spraying mechanism. The second spraying mechanism 61 is installed on the mounting plate 23. At this time, the mounting plate 23 and the pulley block 21 are connected by a rotating intermediate member 51, so as to realize the rotation of the mounting plate 23 through the rotating intermediate member 51. Specifically, during use, after the steam nozzle passes over the surface of the screen printing stencil 200 once, the mounting plate 23 can be rotated so that the second spraying mechanism 61 can face the lower screen printing stencil 200 after rotating half a circle through the mounting plate 23. Subsequently, the upper surface of the screen printing stencil 200 is sprayed and cleaned by the second spraying mechanism 61, so as to dilute and mix the large pieces of ink remaining on the screen printing stencil 200 to prevent the ink from adhering and forming a film again.

[0036] According to Figure 5 and Figure 9As shown, the rotating intermediate member 51 includes: a rotating shaft 511 divided into two sections that can rotate relative to each other. Fixed blocks 512 are respectively installed on the two rotatable parts of the rotating shaft 511. Through holes are symmetrically formed in one of the fixed blocks 512. A spring 513 is placed in the through hole, and a top bead 514 is placed in the through port. The top bead 514 is kept in a popped state by the spring 513. A cover plate 515 is installed on the fixed block 512 to prevent the top bead 514 from popping out of the through hole. A fitting groove 516 matching the top bead 514 is formed in the fixed block 512 on the other side opposite to the side where the top bead 514 is provided. Specifically, in the normal state, the top bead 514 abuts against the fitting groove 516 through the spring 513, so as to keep 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 disengages from the fitting groove 516, and after rotating half a turn, the top bead 514 can be reinserted into the fitting groove 516. At this time, the trapezoidal cover 34 and the second spraying mechanism 61 just exchange their upper and lower positions.

[0037] According to Figure 5 and Figure 9 As shown, it further includes: a slider 517 is slidably connected to one of the fixed blocks 512, and a card slot 518 allowing the slider 517 to enter is formed at a position on the other fixed block 512 corresponding to the slider 517. After the slider 517 slides into the card slot 518, the two fixed blocks 512 are stuck to each other by the slider 517 and thus cannot rotate. When rotation is required, only the slider 517 needs to be pushed to disengage from the card 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.

[0038] According to Figure 8 As shown, it further includes: a partition plate 72 fixedly arranged on one side wall inside the mounting box 31. There is a gap between the partition plate 72 and the side wall, so as to form an independent cavity inside the mounting box 31. An air extraction conduit 71 is installed outside the mounting box 31, and the air extraction conduit 71 communicates with the independent cavity. After the box opening of the mounting box 31 is attached to the silk screen printing plate 200, the cavity opening of the independent cavity is also attached to the silk screen printing plate 200 together. After attachment, suction is performed outward through the air extraction conduit 71. At this time, in cooperation with the spraying of the spray head 33, the sprayed ink will enter the independent cavity under the suction of the air extraction conduit 71 and be discharged from the air extraction conduit 71, so as to strip and collect the large ink blocks adhering to or hanging on the surface from the silk screen printing plate 200 by suction.

[0039] According to Figure 8As shown in the figure, it further includes a rotating rod 73 rotatably arranged at the end of the cavity opening of the independent cavity. When the independent cavity moves together with the mounting box 31, the rotating rod 73 rotates following the surface of the silk screen printing plate 200. The purpose of setting the rotating rod 73 is that during the movement of the independent cavity, the straight edge at the end will scrape away the ink adhered to the silk screen printing plate 200 when it abuts against the silk screen printing plate 200, and cause these inks to accumulate together, so that they cannot enter the independent cavity. Therefore, after the rotating rod 73 is rotatably installed at the end of the independent cavity, the rotating rod 73 will not scrape away the ink during the movement of the independent cavity, and the ink can enter the independent cavity.

[0040] The above-described embodiments only represent the preferred embodiments of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements and substitutions can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
