Therefore, they are widely used in dust-free operations in electronics, medical, food processing and other industries.

[0003] Screen printing equipment is a device used in screen printing process, mainly used for pattern printing of various flat materials. In the production process of PU gloves, screen printing equipment can be used to print various anti-slip screens, anti-slip patterns or logos on the surface of gloves.

[0004] However, the screen plates of current screen printing equipment are often clogged during use because ink, solvents and impurities accumulated in the pores of the screen plates during the printing process, affecting the printing effect. It is necessary to manually stop the machine and wipe it with a cloth moistened with alcohol. In addition, due to the material and structure of the screen plate, manual cleaning of the screen plate is not only time-consuming and laborious, but may not completely remove the blockage and may even damage the screen plate. At the same time, during the screen printing process, due to the action of the ink scraper and the scraper, some paint will flow out from both sides. This part of the paint cannot be reused due to its long-term retention on the surface of the screen plate or needs to be manually recovered and added with additives before it can be reused.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 8 The present invention provides a technical solution for a printing device for a PU glove anti-slip screen:

[0036] A printing device for a PU glove anti-slip screen, comprising:

[0037] The screen printing machine 1 has a vertical and horizontal linear drive structure and a corresponding control module;

[0038] The printing mechanism 2 is equipped with four pneumatic cylinders, and the back plate is fixed to the driving seat of the linear module of the screen printing machine 1 by bolts;

[0039] The scraper structure 3 is fixed to the connecting pipe at the output end of the printing mechanism 2 through a frame and a screw, and has multiple connecting channels inside, which are connected to the cylinder of the printing mechanism 2 through pipelines, and can be used to blow holes, wipe with alcohol, and air dry the screen plate in a pneumatic manner;

[0040] The scraper blade structure 3 includes a mounting member 301. The mounting member 301 is conical in shape. A frame for sleeve installation is integrally provided on its upper surface in a symmetrical manner. A screw hole is provided at the center of the upper surface of the frame, and is threadedly connected to a screw handle for fixing through the screw hole. A groove is provided inside the cone of the mounting member 301. The mounting member 301 is in a claw shape as a whole, and is fixedly connected to the scraper blade body 302 through the groove and bolts.

[0041] A main air passage 3021 is provided at the lower part of the scraper body 302, and the middle part of the main air passage 3021 extends upward along the plate path of the scraper body 302 and penetrates the scraper body 302. A connection interface is integrally provided at the upper end of the main air passage 3021 on the upper surface of the scraper body 302, and is fixedly connected with the air pipe 304 through the connection interface. The other end of the air pipe 304 is connected with the air inlet end of the cylinder on the same side of the printing mechanism 2, and a one-way pressure relief valve is provided at the connection position. The interior of the scraper body 302 is opened above the main air passage 3021. A secondary air duct 3022 having a radius smaller than that of the main air duct 3021 is provided, and the secondary air duct 3022 is connected to the main air duct 3021 via a number of connecting air ducts 3023. The connecting air ducts 3023 are distributed in an axial linear array along the main air duct 3021, and the array distance is two-thirds of the length of the main air duct 3021. After the upper end of the connecting air duct 3023 passes through the secondary air duct 3022, it continues to extend upward along the plate body of the scraper main body 302 by one length, and then turns to pass through the plate surface on one side of the scraper main body 302, and a high-pressure jet head 3025 is installed at the through port.

[0042] During operation, the screen printing machine 1 will supply air to the cylinder of the printing mechanism 2, and the cylinder will push the scraper structure 3 to press against the surface of the screen plate and pull it to the opposite side. At the same time, the screen printing machine 1 will further pressurize the cylinder. Due to the increase in pressure, the opening pressure of the pressure relief valve at the end of the air pipe 304 is broken. At this time, the gas inside the cylinder will enter the air pipe 304 and enter the main air channel 3021 inside the scraper body 302 through the air pipe 304. With the continuous input of gas, the main air channel 3021 will be quickly filled with gas and enter the secondary air channel 3022 through the connecting air channel 3023. A part of the gas entering the auxiliary air channel 3022 will continue to flow along the connecting air channel 3023, and will be pressurized by the high-pressure jet head 3025 and then sprayed onto the surface of the screen plate, so as to blow the scraped paint to give it a certain flow state; when cleaning the screen plate, the screen printing machine 1 will continue to pressurize the cylinder on the original basis, and the pressure relief valve will be in a continuously open state, and the gas will be pressurized by the high-pressure jet head 3025 along the above-mentioned path and then sprayed onto the surface of the screen plate, blowing holes in the screen plate during the movement, and preliminarily opening the blocked holes in the screen plate.

[0043] To summarize, by configuring the scraper body 302, the air pipe 304, the main air channel 3021, the auxiliary air channel 3022, the connecting air channel 3023 and the high-pressure jet head 3025, it is possible to cooperate with the screen printing machine 1 and the printing mechanism 2, and utilize the method of pressurization and re-pressurization to stably input gas into the main air channel 3021 through the air pipe 304, and guide the input gas to a specified path so that it is pressurized and sprayed onto the surface of the screen. By utilizing the air impact effect, not only can the scraped paint be mixed and homogenized, the flow state can be maintained, and its long-term adhesion to the screen surface can be avoided, thereby increasing the printing effect, but also the punching operation of sealing the mesh holes of the screen can be realized.

[0044] As an embodiment of the present invention, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, an air push airway 3024 is opened inside the scraper body 302 between the connecting airways 3023, and the air push airway 3024 is composed of several downward branches and a horizontal airway, wherein the lower end of the branch airway is interconnected with the auxiliary airway 3022, and the two ends of the horizontal channel are slidingly limited by a sleeve spring to have an air rod 3026, and one end of the air rod 3026 pointing to the front and rear sides of the scraper body 302 is movably connected to the push back plate 3027 through a connecting piece, and the end of the rotating shaft of the connecting piece is provided with a torsion spring for deflecting the push back plate 3027, and the push back plate 3027 has a trapezoidal main plate and a sub-plate that can be hidden by a spring connection.

[0045] During operation, the gas entering the auxiliary air channel 3022 will simultaneously enter the interior of the air push air channel 3024, and diffuse from the middle position to both ends, and finally push against the end of the air rod 3026, so that the air rod 3026 is pushed to slide along the air push air channel 3024, and the spring sleeved on the surface of the air push air channel 3024 is compressed during the sliding process, until the air rod 3026 pushes the push back plate 3027 to slide out from the interior of the ink scraper body 302, and then the push back plate 3027 will rotate under the action of the connecting piece and the torsion spring, and then the auxiliary plate inside the push back plate 3027 will be moved out from the interior of the push back plate 3027. Figures 2 to 4 Then, the push-back plate 3027 will push back the paint flowing to both sides from both sides under the traction of the scraper body 302, so as to maximize the utilization of the paint.

[0046] In summary, through the arrangement of the scraper body 302, the air push air channel 3024, the high-pressure jet head 3025, the air rod 3026 and the push back plate 3027, the air pressure can be utilized to transform the push back plate 3027 from a hidden state to a removed state, and form a wide-mouthed hugging posture, so that during the mobile printing process, the paint on both sides of the scraper can be pushed back to avoid the accumulation of paint on the surface of the screen plate, thereby avoiding the waste of paint, reducing the workload of recycling, and maximizing the utilization of paint.

[0047] As an embodiment of the present invention, Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, a groove body as long as the main air channel 3021 is provided on the outward side of the scraper body 302, and a web 303 is movably provided inside the groove body, a groove body is provided on the surface of the web 303, and a slightly protruding mop 3031 is fixedly provided inside the groove body, an alcohol liquid channel 3037 as long as the mop 3031 is provided below the web 303, and the alcohol liquid channel 3037 is provided with a plurality of branch holes extending upward along the plate body at equal intervals in the radial direction, and the upper ends of the branch holes are connected to the groove body where the mop 3031 is located, and the web 303 is integrally provided with a special-shaped connecting arm below the two side surfaces adjacent to the mop 3031, wherein the end of the connecting arm close to the printing mechanism 2 is fixed to the butterfly hole rotating tube 3034, and the alcohol liquid channel 3037 and the butterfly hole rotating tube 303 are provided inside the connecting arm. 4 is connected with the ink scraper body 302, a circular plate is fixed to the end of the connecting arm far away from the printing mechanism 2, and a torsion spring 3036 is connected to the plate surface of the circular plate, and the circular plate and the torsion spring 3036 are rotationally limited to one side of the ink scraper body 302, a butterfly hole rotating tube 3034 is rotatably arranged in the main air channel 3021 through a bearing arranged on the opposite side of the torsion spring 3036, a butterfly plate is fixedly arranged at one end of the butterfly hole rotating tube 3034 close to the center of the mop 3031, and is movably connected to the screw rod 3035 through the butterfly plate, a piston is fixedly arranged at one end of the screw rod 3035, and is slidably arranged in the main air channel 3021 through the piston, the main air channel 3021 stores alcohol in the space isolated by the piston of the screw rod 3035, and the surface of the ink scraper body 302 is provided with an interface for replenishing liquid in this area.

[0048] During operation, the gas inside the main air channel 3021 will push the screw rod 3035 to slide along the inner wall of the main air channel 3021, and during the movement of the screw rod 3035, it will not only push the alcohol into the butterfly hole rotating tube 3034, and then enter the alcohol liquid channel 3037 from the butterfly hole rotating tube 3034, and then enter the space where the mop 3031 is located along the alcohol liquid channel 3037 to wet the mop 3031, but the screw rod 3035 will also drive the butterfly hole rotating tube 3034 to rotate through the butterfly hole plate, thereby driving the web 303 to rotate, so that the web 303 is rotated 90 degrees and attached to the surface of the screen plate, and under the traction of the printing mechanism 2, the surface of the screen plate is wiped and cleaned.

[0049] In summary, by configuring the ink scraper body 302, the main airway 3021, the web 303, the mop 3031, the butterfly hole rotating tube 3034, the screw rod 3035, the torsion spring 3036 and the alcohol liquid channel 3037, the air pressure can be used to not only realize the rotation drive of the screw rod 3035 on the butterfly hole rotating tube 3034, so that it drives the web 303 to move out of the groove on the surface of the ink scraper body 302 and attach it to the surface of the screen plate, but also to transfer alcohol through the end of the butterfly hole rotating tube 3034. The butterfly hole is pushed into the alcohol liquid channel 3037, and the mop 3031 is wetted, so that the screen printing machine 1 and the printing mechanism 2 can be cooperated to wipe and clean the screen plate, and the treatment effect of blocking the mesh holes on the surface of the screen plate is further enhanced to avoid the blockage of the mesh holes on the surface of the screen plate. At the same time, compared with manual cleaning, the evenly-moving and wiping cleaning method will not have uneven force application, and will not cause damage to the screen plate while ensuring the cleaning effect and efficiency.

[0050] Working principle: When working, firstly, alcohol is added to the space where the butterfly hole rotating tube 3034 and the screw rod 3035 are located through the interface for replenishing liquid, and then the screen printing machine 1 can be controlled to drive the printing mechanism 2 to perform printing operations normally. During operation, the screen printing machine 1 will supply air to the cylinder of the printing mechanism 2, and the cylinder will push the scraper structure 3 to press against the surface of the screen plate and pull it to the opposite side. At the same time, the screen printing machine 1 will further pressurize the cylinder (at this time, the amount of pressure relief and exhaust required by the pressure relief valve exceeds the load range of the pressure relief valve, but due to the friction between the torsion spring 3036 and the screw rod 3035, the screw rod 3035 will not slide at this time). Due to the increase in pressure, the opening pressure of the pressure relief valve at the end of the air pipe 304 is broken through. At this time, the gas inside the cylinder will enter the air pipe 304, and enter the main air channel 3021 inside the scraper body 302 through the air pipe 304. As the gas continues to be input, the main air channel 3 021 will be quickly filled with gas and enter the secondary airway 3022 through the connecting airway 3023. A part of the gas entering the secondary airway 3022 will continue to flow along the connecting airway 3023 and be pressurized by the high-pressure jet head 3025 and then sprayed onto the surface of the screen plate to blow the scraped paint to give it a certain flow state. The gas entering the secondary airway 3022 will simultaneously enter the interior of the air-pushing airway 3024 and diffuse from the middle position to both ends, and finally push on the end of the gas rod 3026 to push the gas rod 3026 to slide along the air-pushing airway 3024 and compress the spring sleeved on the surface of the air-pushing airway 3024 during the sliding process until the gas rod 3026 pushes the push-back plate 3027 to slide out from the inside of the ink scraper body 302, and then the push-back plate 3027 will rotate under the action of the connecting piece and the torsion spring, and then the secondary plate inside the push-back plate 3027 will be moved out from the inside of the push-back plate 3027 as shown in FIG. Figures 2 to 4, and then the push-back plate 3027 will push back the paint flowing to both sides from both sides under the traction of the ink scraper body 302, so as to maximize the utilization of the paint; and when cleaning is needed, first remove the paint on the surface of the screen plate, and then control the screen printing machine 1 to drive the printing mechanism 2 to perform the printing operation normally, and the screen printing machine 1 will continue to pressurize the cylinder on the original basis (at this time, the amount of pressure relief and exhaust required by the pressure relief valve is greater than the amount of pressure relief and exhaust when the screen printing machine 1 is in the working state), the pressure relief valve is in a continuously open state, and the gas will be pressurized and sprayed on the surface of the screen plate through the high-pressure jet head 3025 along the above path, and the screen plate will be blown holes during the movement, and the blocked holes of the screen plate will be preliminarily opened. At the same time, the gas inside the main airway 3021 will push the screw rod 3035 to slide along the inner wall of the main airway 3021, and during the movement of the screw rod 3035, it will not only Alcohol is pushed into the butterfly hole rotating tube 3034, and then enters the alcohol liquid channel 3037 through the butterfly hole rotating tube 3034, and then enters the space where the mop 3031 is located along the alcohol liquid channel 3037 to wet the mop 3031, and the screw rod 3035 will also drive the butterfly hole rotating tube 3034 to rotate through the butterfly hole plate, thereby driving the web 303 to rotate, so that the web 303 is rotated 90 degrees and attached to the surface of the screen plate, and under the traction of the printing mechanism 2, the surface of the screen plate is wiped and cleaned. After cleaning, the continuous air supply operation of the cylinder can be released, and then the cylinder will drive the scraper structure 3 to move upward. At the same time, the web 303 will be rotated and reset to the groove on the surface of the scraper body 302 under the action of the torsion spring 3036, and the screw rod 3035 will be reset to the initial position along the main air channel 3021 under the reverse drive of the butterfly hole rotating tube 3034, and then the screen printing operation can be performed.

[0051] It should be noted that in order to prevent the added ink from being too dry, the device has adjusted the blowing parameters such as temperature, speed and distance by technicians according to the type of ink used and printing conditions, which can ensure that the ink obtains appropriate drying time and environment and does not cause the ink to be too dry and affect the printing effect.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
