[0002] When a screen printing machine is used to print on a substrate, the ink is transferred to the substrate through the mesh holes through the extrusion of the scraper, forming the same image and text as the original. The screen printing equipment is simple and easy to operate. Printing and plate making are simple and low-cost, and the adaptability is strong. Screen printing is a commonly used printing process, which is characterized by the ability to print many types of materials.

[0056] As a technical optimization scheme of the present invention, the film arrangement conveyor 2 has a conveyor frame 202, and a plurality of conveyor rollers 2022 are rotatably installed on the top of the conveyor frame 202 through bearings. A protective cover 2026 is arranged at the front position of the top of the film arrangement conveyor 2, and a reduction motor 2021 is arranged at the upper position inside the conveyor frame 202, and the driving shaft of the reduction motor 2021 is connected to the conveyor rollers 2022 through a transmission chain. A lifting cylinder 2025 is arranged at the rear position inside the conveyor frame 202, and a belt transmission shuttle assembly 2023 is arranged at the top of the push rod of the lifting cylinder 2025.

[0057] The belt transfer shuttle assembly 2023 is provided to facilitate the arrangement and reception of the plates delivered by the narrow sheet printing machine 1, and the servo reduction motor 2024 is provided to facilitate the control of the moving step distance of each sheet placement.

[0058] As a technical optimization solution of the present invention, the two transmission frames and the transmission shuttle are in the same straight line, and the transmission shuttle assembly 2023 does not contact the transmission roller 2022. After the push rod of the lifting cylinder 2025 is retracted to the limit, the top surface of the transmission shuttle assembly 2023 does not exceed the transmission roller 2022.

[0059] The belt transmission shuttle assembly 2023 can be raised and lowered as a whole by the lifting cylinder 2025, so that it can be adjusted according to needs to facilitate material connection and sheet transfer.

[0060] As a technical optimization scheme of the present invention, the drying machine box 3 has a zone one dryer 3031 and a zone two dryer 3031. A conveyor mesh belt is installed at a lower position inside the drying machine box 3 through a rotating roller, and a drying reduction motor is installed at one side of the rear end of the drying machine box 3, and the driving shaft of the drying reduction motor is connected to the conveyor mesh belt through a transmission chain group, and the height of the conveyor mesh belt matches the height of the transmission roller 2022. An axial flow fan, an exhaust fan and an exhaust valve matching the zone one dryer 3031 and the zone two dryer 3032 are installed at the top of the drying machine box 3. A fresh air compensation device is installed at the bottom of the drying machine box 3, and a filter assembly is provided at the air inlet of the fresh air compensation device. A cooling fan is provided at the top of the air cooler 4, and the air cooling zone of the air cooler 4 is two meters.

[0061] The axial flow fan is provided to draw air into the drying machine box 3, and the inhaled air is heated by the first zone dryer 3031 and the second zone dryer 3032, so that the entire drying machine box 3 is filled with hot air, which is convenient for drying and curing the printed pattern on the sheet. The cooling fan at room temperature draws in cold air from the air cooler 4 and sprays it on the surface of the dried sheet, which is convenient for quickly reducing the temperature of the sheet to room temperature.

[0062] When the present invention is in use, the sheet is manually placed on the table of the table component 601 so that it is located above the first vacuum suction cup 5015 on the shuttle in the transmission component 501. At the same time, because the narrow sheet printer 1 is provided with a foot switch that matches the cylinder 3 5016, the foot switch 1 can be stepped on after placement to make the cylinder 3 5016 in the transmission component 501 actuated, thereby lifting the shuttle in the transmission component 501 and making it rise vertically under the limit of the linear bearing 3 5014. At this time, the vacuum suction cup 5015 on the shuttle is simultaneously actuated, so that the vacuum suction cup 5015 can contact the placed sheet during the rising process and suck the sheet, so as to lift the sheet on the table.

[0063] After the cylinder 3 5016 is extended to the right position, a signal is sent out. Since the shuttle mounting plate 5013 is mounted on the linear guide rail 5012 through the slider, and the shuttle top extension cylinder 5017 is connected to the shuttle mounting plate 5013 through the shuttle connecting plate 5018, the activity mode of the shuttle top extension cylinder 5017 can be controlled to drive the two shuttles in the transmission component 501 to move backward along the linear guide rail 5012. When the slider moves to the limit distance and the shuttle top extension cylinder 5017 is retracted to the limit, the vacuum suction cup 5015 can stop suctioning and release the plate. Then, the cylinder 3 5016 is retracted to drive the two shuttles in the transmission component 501 to descend, so that the sheet is placed on the table in the table component 601 again. After the sheet is placed, the linear guide rail 5012 can be driven forward again by the shuttle top extension cylinder 5017 to reset.

[0064] At the same time, the six slide cylinders 6013 in the table component 601 move and extend at the same time to position the sheet. After the sheet is positioned, the table suction cup 6012 moves to adsorb the sheet on the table. Then the above steps are repeated, so that the cylinder 3 5016 drives the vacuum suction cup 5015 to extend. After the vacuum suction cup 5015 extends and adsorbs the sheet, the table suction cup 6012 is controlled to stop suction. Then, the shuttle top extension cylinder 5017 drives the two shuttles on the shuttle mounting plate 5013 to move forward along the linear guide rail 5012 again. The transmission of the sheet is the action process of the shuttle of the transmission component 501 repeatedly rising and falling and moving.

[0065] When the sheet is transferred to the printing position, the second printing foot switch can be stepped on to make the second cylinder 4012 extend downward. Because the scraper assembly 3011 and the ink return knife assembly 3012 are installed on the printing head mounting plate 2012 of the printing arm assembly 201 through the printing head support in the printing head assembly 301, and the printing arm assembly 201 is installed on the printing arm connecting support 4013, when the second cylinder 4012 is extended, it will drive the printing arm assembly 201 to move downward along the guide slide column 4016 in the screen lifting frame assembly 401 until the second cylinder 4012 is extended. After reaching the position, a signal is sent to retract the cylinder 1 3014 matching the scraper assembly 3011 in the printing head component 301, thereby putting down the scraper assembly 3011. After the cylinder 1 3014 is actuated, a signal is sent again to actuate the rodless cylinder 2011 in the printing arm component 201, thereby driving the printing head component 301 to move leftward along the guide shaft 2015. At the same time, when the rodless cylinder 2011 is actuated, the off-screen cylinder 1017 in the screen clamping component 101 can be controlled to extend slowly, thereby slowly lifting the screen plate component to a suitable height.

[0066] After that, after the rodless cylinder 2011 drives the printing head component 301 to move to the left and detects the limit signal, the cylinder 2 4012 is controlled to retract, thereby driving the printing arm component 201 to be lifted together with the printing head component 301, until the cylinder 2 4012 is extended into place, the cylinder 1 3014 matched with the ink return knife assembly 3012 is retracted, thereby putting down the ink return knife assembly 3012, and then the rodless cylinder 2011 of the printing arm component 201 is actuated, thereby driving the printing head component 301 to move to the left together, and driving the ink return knife assembly 3012 to move to the left for resetting, and at the same time, after the rodless cylinder 2011 is moved, the off-grid cylinder 1017 is controlled to retract, and the screen plate is put down again, and then after the printing head component 301 is reset, the cylinder 1 3014 matched with the ink return knife assembly 3012 can be controlled to move, thereby lifting the ink return knife assembly 3012 again for the next use, thereby completing the printing process;

[0067] When printing is completed, the above-mentioned sheet material transporting action can be repeated, and the two transport shuttles on the transport component 501 can be driven by the shuttle top extension cylinder 5017 to move backward along the linear guide rail 5012 to transport the printed screen to the sheet conveyor 2;

[0068] At the same time, during the screen transmission, the push rod of the lifting cylinder 2025 in the sheet conveyor 2 can be controlled in advance to push out in place to wait for the shuttle on the narrow sheet printing machine 1 to send the sheet. When the two sets of shuttles on the narrow sheet printing machine 1 extend, the sheets are placed on the two sets of belts in the belt transmission shuttle assembly 2023 of the sheet conveyor 2, and the photoelectric detection device detects the sheet release signal, the servo reduction motor 2024 is controlled to operate. Because the driving shaft of the servo reduction motor 2024 is connected to the pulley of the belt transmission shuttle assembly 2023 through the transmission shaft, the belt on the belt transmission shuttle assembly 2023 can be rotated by the servo reduction motor 2024 to drive the pulley to rotate, thereby driving the sheet placed thereon to move;

[0069] And through the above steps, the moving step distance of each sheet placement can be controlled by adjusting the number of rotations of the servo reduction motor 2024. When the sheet on the belt transmission shuttle assembly 2023 is placed enough and the photoelectric detection device at the left end detects the sheet, a signal is sent to control the lifting cylinder 2025 to retract, because the belt transmission shuttle assembly 2023 is installed in the gap of the transmission roller 2022;

[0070] Therefore, when the belt transmission shuttle assembly 2023 moves downward, the sheet can be placed on the transmission roller 2022. After that, when the lifting cylinder 2025 is retracted to its position and the belt transmission shuttle assembly 2023 is no longer in contact with the sheet, the reduction motor 2021 can be controlled to move. Since the driving shaft of the reduction motor 2021 is connected to the transmission roller 2022 by chain transmission, the driving shaft of the reduction motor 2021 can be rotated to drive the transmission roller 2022 to rotate, so that the sheet moves to the next station under the force of the rotation of the transmission roller 2022.

[0071] Because a conveyor mesh belt matching the transmission roller 2022 is installed in the drying machine box 3 through a rotating roller, and a drying reduction conveying motor matching the conveyor mesh belt is installed on the drying machine box 3, and the driving shaft of the drying reduction motor is connected to the rotating roller of the conveyor mesh belt through a chain drive, the conveyor mesh belt can be driven by the driving shaft of the drying conveying motor to rotate, so that the sheets sent from the sheet conveyor 2 can be transmitted to the first zone dryer 3031 and the second zone dryer 3032. Because an axial flow fan is installed on the top of the box body of the drying machine box 3, it plays a role in bringing wind into the drying machine box 3, and the inhaled wind is heated by the first zone dryer 3031 and the second zone dryer 3032, so that the entire drying machine box 3 can be filled with hot air;

[0072] Therefore, when the sheet passes through the drying box 3, the sheet is heated quickly, and after the sheet passes through the first zone drying machine 3031 and the second zone drying machine 3032, the printed pattern is dried and solidified in a short time. At the same time, before heating, the temperature in the first zone drying machine 3031 and the second zone drying machine 3032 can be independently controlled so as to be set according to the ink solidification temperature;

[0073] After the sheet is dried in the drying box 3, it is transmitted to the inside of the air cooler 4 along with the conveyor belt. The cooling fan at the air cooler 4 draws in cold air at room temperature and sprays it on the surface of the dried sheet, so that the temperature of the sheet can be quickly reduced to room temperature.
