Semiautomatic silk screen printer for PP package box sheet

Screen printing machine is a representative printing equipment in stencil printing machine. It is good used for the PP hollow corrugated sheet for package box.Its printing plate is a criss-crossing, warp and latitude wire mesh woven from materials such as silk. A variety of screen printing machines, such as planes, curved surfaces, forming, printing and dyeing, printed circuits and new types of rotary printing, have been produced. Among them, the new rotary screen printing machine has a relatively high speed and productivity. It is characterized in that the screen is mounted on the drum and the ink is poured into the drum. The drum rotates while the machine is working, and the squeegee prints the pattern quickly onto the print.
In addition to the silk material, nylon wire, copper wire, steel wire or stainless steel wire can be used. The principle of stencil printing for screen printer applications originated from ancient stencil printing. The stencil printing has various forms such as stencil printing, stencil printing and screen printing.
Screen printing was originally hand-operated, with only one plate, one screen and one plate. In the 1950s, screen printing was mechanized and automated. The drum screen printing machine has a large amount of ink when printing. It is suitable for printing thick printed ink. It can be printed on various paper, glass, wood, metal, ceramic, plastic or cloth. It can be used in a variety of inks, including conductive. Metallic ink


Performance advantage

1) oblique arm structure.

2) the lifting and lifting of the printing arm -- it adopts the frequency conversion system and the connected reducer, and the speed is adjustable.

3) drag of the printing knife -- variable frequency drag system drives the printing tool holder and synchronous belt drive.

4) separate adjustment and control of printing/ink return speed, convenient travel adjustment.

5) stainless steel bond printing platform, decorated with fine adsorption holes for less than 30 minutes 1.0~1.5, strong vacuum automatic adsorption.

6) the horizontal and vertical direction of the printing platform is set with accurate adjustment, and the multi-color matching is accurate.

7) pneumatic disconnecting device, effectively preventing large area of printing paper and printing pattern paste.

8) 2 sets /4 cylinders ensure the balance and stability of printing and ink return pressure, and the ink scraper and ink return knife automatically switch.

9) the Angle of scraping and ink return can be adjusted, and the operation is flexible and convenient.

Screen printing machine main structure
Transmission: motor, electromagnetic clutch, reducer, speed governing mechanism.
Plate printing device: The screen printing plate must be fixed on the printing plate device in the screen printing machine, and in the printing process, the uncovering type lifting or horizontal lifting is realized. Mainly: plate holder, plate landing mechanism, plate adjustment mechanism, lifting net compensation mechanism.
Printing device: squeegee and ink return are the main actions to achieve silk screen printing. The squeegee system and ink return system are usually installed on the squeegee carriage. In the reciprocating motion, the squeegee and the ink return plate are alternately moved up and down. Achieve the ink scraping and ink returning action.
1 printing reciprocating stroke realization, generally adopts the following mechanisms: crank linkage mechanism, crank slider mechanism, chain sprocket mechanism, cylindrical plug magnetic cylinder.
2 Guide mechanism generally adopts the following forms: roller groove rail, double guide shaft, guide shaft and slider.
3 scraping, ink return plate transposition mechanism often uses the following form:
Step slot lifting block plus lever transposition mechanism, cam lifting mechanism plus lever transposition mechanism, two cylinder reverse action or single cylinder plus lever mechanism, cam-swing bar mechanism pulling wire and lever mechanism, chain hanging point change makes two plates In the swinging step position, when a scraper is used instead of two scrapers, an ink jump action is required, and the ink jump action is performed by a specific mechanism.
The support device is the printing platform: it is used to fix the substrate.
1 should have a print positioning device.
2 platform height and level adjustment device.
Pairing mechanism: The position of the platform when moving against the plate is generally achieved by mechanical threading, and should have reliable locking device and shifting guide (dovetail groove or guide key, etc.).
Drying device: infrared electric heating tube hot air drying or ultraviolet curing drying device.
Electrical control device: work cycle control, scraper position control, air pressure control.

Screen printing machine works
1 The work cycle program of the flat screen printing machine is a flat screen type monochrome semi-automatic hand screen printing machine. Its working cycle is: feeding piece → positioning → falling plate → reducing the ink board, Raise back to the ink board → Scrape stroke → Raise the squeegee → Return to the ink board → Lift the plate → Return the ink stroke → Unposition → Receive.
In the continuous cycle action, as long as the function can be realized, the time occupied by each action should be as short as possible to shorten the synchronization of each work cycle and improve work efficiency.
3 embossed lines. During the printing process, the squeegee presses the ink and the screen plate to form a line of contact between the screen plate and the substrate, called the nip. This line is at the edge of the squeegee, and numerous embossed lines form the printed surface. Achieving an ideal embossing line is difficult because the printing stroke is a dynamic process.
3 screen printing machine works. Taking the commonly used hand-screen screen printing machine as an example, the working principle of the screen printing machine can be described as follows: the transmission mechanism transmits power, and the squeegee plate squeezes the ink and the screen printing plate during the movement to make the screen The printing plate and the substrate form an embossing line. Since the screen has the tensions N1 and N2, the force F2 is generated on the squeegee plate, and the resilience makes the screen printing plate not contact with the substrate except the embossing line. Under the action of the pressing force F1 of the squeegee, it is leaked from the moving nip to the substrate through the mesh.
During the printing process, the screen printing plate and the squeegee plate are moved relative to each other, and the squeezing force F1 and the resilience force F2 are also synchronously moved. Under the action of the resilience force, the screen is timely returned to contact with the substrate, so as to avoid The blot is dirty. That is, the screen is constantly in the process of deformation and rebound during the printing process.
After the squeegee finishes unidirectional printing, it is separated from the substrate together with the screen printing plate, and at the same time, returning ink is returned, that is, a printing cycle is completed. The distance between the top of the substrate and the opposite side of the screen printing plate after ink return is called the same plate spacing or mesh distance, and should generally be 2 to 5 mm. When hand-printed, the manipulation and proficiency of the operator directly affects the formation of the embossed line. In practice, silk screen workers have accumulated a lot of valuable experience, which can be summarized as six points, that is, to ensure linearity, uniformity, equiangularity, pressure equalization, centering and vertical edge in the movement of the squeegee. That is to say, when printing, the squeegee should be straight forward and cannot be shaken left and right; it cannot be slow before and after fast, slow or slow before and after; the tilt angle to the ink plate should remain unchanged, pay special attention to overcome the tilt angle Increasingly common problems; the printing pressure should be kept uniform; keep the distance between the squeegee and the inside of the frame equal; the ink plate is perpendicular to the frame
