Description

Technical Field

[0001] The invention relates to the technical field of printing, in particular to a screen printing machine for printing with a protective structure. Background Art

[0002] Printing is a technology that transfers ink from originals such as text, pictures, photos, anti-counterfeiting, etc. to the surface of paper, fabric, plastic, leather and other materials through processes such as plate making, inking, and pressurization, in order to batch reproduce the content of the originals.

[0003] The screen printing machine works on the basic principle that the mesh holes of the screen printing plate are permeable to ink, while the mesh holes of the non-image and text parts are not permeable to ink. Specifically, when printing, ink is poured into one end of the screen printing plate, and then a certain pressure is applied to the screen printing plate through a scraper, so that the ink leaks from the mesh holes of the image and text part to the substrate under the pressure of the scraper, thereby realizing the reproduction and printing of the image and text.

[0022] The present invention provides a screen printer for printing with a protective structure, which has the following beneficial effects:

[0023] The screen printing machine with a protective structure for printing has a height adjustment component and a support component. When the height of the printing machine needs to be adjusted, the first reduction motor is started, and the conveying component is driven to move up and down through the bidirectional screw, two moving blocks, the first U-shaped block, the support column, the second U-shaped block and the U-shaped plate. The height of the conveying component can be adjusted according to the height of the user, so that users of different heights can load materials and the convenience of using the device is improved. The two support components improve the stability when adjusting the height.

[0024] The screen printing machine with a protective structure for printing has a height adjustment component and a moving component. When the printing machine needs to be moved, the first reduction motor is started, and the conveying component is driven to move downward through the bidirectional screw, the moving block, the first U-shaped block, the support column, the second U-shaped block and the U-shaped plate. When the U-shaped plate contacts the cushion block, the bottom plate is driven to move upward, and at the same time, four universal wheels pass through corresponding rectangular holes on the bottom plate and contact the ground. The screen printing machine can be moved through the four universal wheels, thereby improving the convenience of moving the printing machine.

[0025] The screen printing machine with a protective structure for printing has a conveying component and a vacuum pump component. When the printing machine is used, when an object moves to the bottom of the screen, the vacuum pump body is started, and at the same time, the second solenoid valve is opened to adsorb the object through the second telescopic hose, the connecting pipe and the large adsorption plate, so that when the object is printed, the object will not be displaced due to contact with the screen, thereby improving the accuracy of printing.

[0026] The screen printer with a protective structure for printing uses a limiting component. When the printer is used, the position of the sliding block in the installation frame is adjusted according to the size of the object and the printing position. Then, two butterfly screws are used to pass through the rectangular groove on the top of the installation frame and the screw holes on the sliding block to fix the position of the sliding block. When loading, the object is placed on the top of the conveyor belt, and the diagonal of the object is made to correspond to the angle formed by the installation frame and the limiting rod, so that the accuracy during printing can be improved.

[0027] The screen printing machine for printing with a protective structure uses a printing machine through a blanking component to carry out blanking. When the printed object reaches directly below the blanking component, the third reduction motor starts to drive the printing component and the blanking component. When the small adsorption plate approaches the object, the first electromagnetic valve is opened, and the object is adsorbed by the first telescopic hose, the vent pipe, the five-way pipe, the installation hose, the vent pipe, the connecting pipe and the small adsorption plate. When the fourth reduction motor is started, the second threaded rod, the large bevel gear, the first small bevel gear, the second small bevel gear and the third threaded rod drive the T-block, the fixed frame, the connecting pipe, the small adsorption plate, the five-way pipe, the installation hose and the vent pipe to move. The second slider drives the support plate and the electric push rod to move to the leftmost end, and the small adsorption plate drives the object to move to the leftmost end. Then the first electromagnetic valve is closed, and the object falls. When the second slider drives the support plate and the electric push rod to move to the rightmost end, the small adsorption plate is reset and moves to the rightmost end at the same time, so that the material can be automatically blanked, thereby improving the convenience of blanking.

[0057] The use method of the present invention: The screen printer for printing with a protective structure, when in use, has the following working process:

[0058] like Figures 1 to 12As shown, firstly, the screen printing machine is moved to the place of use by four universal wheels 305, and then the first reduction motor 104 is started, and the bottom plate 101 is driven to move downward by the bidirectional screw 105, two moving blocks 106, the first U-shaped block 107, the support column 108, the second U-shaped block 109 and the U-shaped plate 1010. When the bottom plate 101 contacts the ground, the conveying assembly 5 is driven to move upward. When the conveying assembly 5 is adjusted to a suitable height, the first reduction motor 104 is stopped, and then the position of the limit rod 603 is adjusted. After adjusting to a suitable position, two butterfly screws are passed through the rectangular groove on the top of the installation frame 601, and the position of the sliding block 602 is fixed through the screw holes on the sliding block 602. Then, the printing to be performed is performed. The object is placed on the top of the conveyor belt 506, and the diagonal angle of the object corresponds to the angle formed by the installation frame 601 and the limit rod 603, then the second reduction motor 507 is started, and the second reduction motor 507 drives the conveyor belt 506 to rotate through the second connecting rod 503 and the second conveying roller 505 to convey the object from right to left. The object passes through the bottom of the L-shaped frame 7, and the distance sensor at the bottom of the inner wall of the L-shaped frame 7 senses it. When the object moves to the bottom of the screen, the vacuum pump body 402 is started, and the second solenoid valve 405 is opened to absorb the object through the second telescopic hose 407, the connecting pipe 509 and the large suction plate 508. Then the third reduction motor 803 is started, and the first threaded rod 804, the first sliding rod 805 and the second solenoid valve 405 are opened. The block 805 and the fixed plate 806 drive the printing assembly 9 and the blanking assembly 10 to move downward. When the printing assembly 9 is located at the top of the object, the third reduction motor 803 is stopped, and then the fourth reduction motor 903 and the two electric push rods 908 are started. The fourth reduction motor 903 is started, and the support plate 907 and the electric push rod 908 are driven to move to the left through the second threaded rod 904 and the second slider 906.

Then the third reduction motor 803 is started to drive the printing assembly 9 and the blanking assembly 10 to move upward, and then the second solenoid valve 405 is closed, and the second reduction motor 507 is started, so that the conveyor belt 506 drives the object to move. According to the same raw material, Printing is continuously performed. When the next printing is performed, the printed object reaches the bottom of the blanking assembly 10. When printing is performed, the third reduction motor 803 is started to drive the printing assembly 9 and the blanking assembly 10 to move downward. When the small adsorption plate 1009 approaches the object, the first solenoid valve 404 is opened, and the object is adsorbed by the first telescopic hose 406, the vent pipe 10012, the five-way pipe 10010, the installation hose 10011, the vent pipe 10012, the connecting pipe 1008 and the small adsorption plate 1009. When the fourth reduction motor 903 is started, the third threaded rod 1003 is driven to rotate by the second threaded rod 904, the large bevel gear 905, the first small bevel gear 808 and the second small bevel gear 1004.The third threaded rod 1003 rotates through the third slider 1005 to drive the T-block 1006, the fixed frame 1007, the connecting pipe 1008, the small suction plate 1009, the five-way pipe 10010, the installation hose 10011 and the vent pipe 10012 to move, the second slider 906 drives the support plate 907 and the electric push rod 908 to move to the far left, and the small suction plate 1009 drives the object to move to the far left, then closes the first solenoid valve 404, and the object falls. When the second slider 906 drives the support plate 907 and the electric push rod 908 to move to the far right, the small suction plate 1009 resets and moves to the far right at the same time, and the two protective gratings 11 installed on the conveying frame 501 are opened. When the user approaches the moving adjustment component 8, the printing component 9 and the unloading component 10 from the front, the protective grating 11 senses and stops the motor and the electric push rod 908 on the printing press.
