Product Description

Pneumatic turntable flat screen printer
Structural composition
1. Pneumatic turntable workbench:
• Turntable body: Made of sturdy and durable metal materials, such as stainless steel or aluminum alloy, with good rigidity and stability, ensuring that there will be no deformation when frequently rotating and carrying substrates. The turntable is carefully divided into multiple stations, including loading station, printing station, drying station (if equipped with drying function), unloading station, etc. The layout of each station is reasonable, which is convenient for orderly carrying out different production links.

• Pneumatic drive device: The turntable is driven to achieve intermittent rotation through a pneumatic system composed of cylinders, air pipes, solenoid valves, etc. The air source provides stable compressed air, which is transmitted through the air pipe. The solenoid valve accurately controls the direction and on-off of the air flow, so that the cylinder drives the turntable to rotate according to the set rhythm, and can accurately control the rotation angle to ensure accurate alignment of each station, which facilitates the smooth progress of subsequent operations.

• Metal pin block positioning structure: Metal pin blocks are set on each station of the turntable. These pin blocks are precisely matched with the corresponding positioning holes and positioning grooves on the substrate or the fixture for placing the substrate, which can firmly lock the position of the substrate. Even if the substrate is irregular in shape or small in size, it can remain motionless during the printing process to ensure the accuracy of the position of the printed pattern.

2. Pneumatic screen up and down device:

• Cylinder assembly: The core component is the cylinder, which can provide sufficient and stable power to drive the screen to move up and down in the vertical direction. At the same time, it is equipped with high-precision guide mechanisms, such as guide rods, linear bearings, etc., to ensure that the screen maintains a linear motion state during the up and down movement, and prevent skew, jamming, etc. that affect printing.

• Connectors and adjustment components: The screen and the cylinder are reliably connected through special connectors to ensure the coordinated movement of the two. It is also equipped with an adjustment device, which can easily fine-tune the initial height, up and down travel range of the screen to adapt to substrates of different thicknesses and different printing process requirements, and flexibly control the distance between the screen and the substrate.

3. Control system:

• Based on a simple single-chip microcomputer operation panel, the operator can easily control the rotation speed and pause time of the pneumatic turntable, adjust the height and speed of the pneumatic screen, and set the number of printings, the pressure of the squeegee (by adjusting the relevant mechanical structure), etc.

Working principle

    First, the operator places the substrate to be printed on the loading station of the pneumatic turntable workbench, and accurately fixes the substrate with the help of the metal pin block positioning structure. Subsequently, the pneumatic screen upper and lower device controls the screen to descend, contact the substrate to start printing, and the squeegee moves on the screen printing plate according to the set pressure and direction, squeezing the ink from the graphic part of the printing plate onto the substrate to complete one printing, and the ink return plate simultaneously scrapes the excess ink back to the corresponding position on the printing plate. After printing is completed, the turntable continues to rotate and sends the substrate to the next station (such as the drying station for ink drying, or directly to the unloading station). This cycle continues until the substrate completes all processes and is taken out from the unloading station. The whole process can be repeated continuously to achieve continuous batch production.

Features and advantages

1. High positioning accuracy: The combination of metal pin block positioning and precise station switching of the pneumatic turntable can ensure that the substrate is in the correct position at all links, greatly improving the positioning accuracy of the printed pattern on the substrate, making the printed pattern clear and accurate, especially suitable for product printing with strict requirements on the pattern position, such as electronic product panels, signboards, etc.

2. Easy to operate: The pneumatic drive mode is relatively simple and intuitive to operate. The turntable rotation and the screen up and down can be realized by adjusting the relevant pneumatic parameters through the control system. There is no need for complex mechanical transmission debugging, which reduces the professional skills requirements for operators. At the same time, it is also convenient for daily maintenance and maintenance of the equipment, reducing the probability of equipment failure.

3. Good equipment stability: Pneumatic components themselves have the characteristics of simple structure, reliable action, strong anti-interference ability, etc. Under the reasonable pneumatic system design, the overall operation of the equipment is stable and can work continuously for a long time, reducing production interruptions caused by equipment failures, helping to improve production efficiency and ensure the smooth completion of production plans.

4. Cost-effectiveness advantage: Compared with some printing equipment that use complex and expensive drive methods such as high-precision electric servo systems, the pneumatically driven screen printing machine is usually lower in equipment procurement costs, and the maintenance and replacement costs of pneumatic components are relatively small. It is more suitable for small and medium-sized enterprises or production scenarios that are more sensitive to costs. Under the premise of ensuring a certain printing quality, it can effectively control production costs.

5. Wide applicability: It can adapt to the printing needs of various materials (such as plastics, metals, glass, etc.) and flat substrates of different sizes and shapes. It has strong versatility and can be used in advertising, gift packaging, electronic accessories and other industries.
