JB-145AS Servo Motor Controlled Automatic Stop Cylinder Screen-Printing Machine

Short Description:


Product Detail

It is a new type of intelligent screen printing machine independently developed and designed by our company with completely independent intellectual property rights. It has three invention patents and five utility model patents. The speed of full-size printing can be up to 3000 pieces / hour under the requirement of ensuring the quality of printing products. It is the best choice for paper and plastic packaging, ceramic and cellophane, textile transfer, metal signs, plastic film switches, electronic and electrical components and other industries.

The machine abandons the traditional single power source belt drive shaft, gearbox and chain mode, uses multiple servo motors to drive feeder, conveying, roller and mesh frame respectively, ensures the synchronization of several functional units through automatic control, not only eliminates a large number of mechanical transmission parts, but also greatly improves the rigidity of printing machinery, and reduces the errors caused by mechanical transmission device Poor, improve the printing quality and mechanical efficiency, improve the automation level of the production process, improve the working conditions of the environment.

Features:

1. Paper feeding feeder: offset Feeder head, higher speed, reliability and stability.

It has strong adaptability to the thickness of printed parts, and ensures smooth paper feeding at high speed; 

The paper feeder can choose by itself and switch single sheet or laminated paper by one button. 

2. Paper feeding table:

The stainless steel paper feeding table can effectively prevent the back of substrate from being scratched, and reduce the static friction between the table and substrate; 

With vacuum adsorption at the bottom of the table, with the structure of pushing paper and pressing paper on the table, to ensure the smooth transportation of various materials; 

When a single sheet of paper is fed, the conveyor belt slows down at the right time to ensure that the substrate is stable and in place at high speed. 

3. Pneumatic side gauge: 

The downward suction vacuum side pull gauge will not cause white and dirty paper and text marks. 

One body variable push gauge type, one key switch, start and control push gauge pull gauge conversion. 

Push pull positioning is accurate, positioning stroke is long, positioning speed is fast, and adjustment is convenient. The photoelectric detection system can monitor the position of printed parts in real time and reduce the rate of printing waste. 

4. Shaftless system: traditional single power source of main drive with multiple drive modes 

Using synchronous drive technology, the transmission shaft, gearbox and other mechanical devices are removed, and multiple servo motors are used to follow the virtual electronic spindle. A large number of mechanical transmission parts have been eliminated.

Noise reduction: the traditional main shaft and gearbox are discarded, the moving parts are reduced, the mechanical structure is simplified, and the components generating mechanical vibration are reduced, so the noise is greatly reduced in the operation process..

5. Heavy pneumatic scraping system: comprehensive application of electrical, pneumatic, hydraulic technology, automatic control of scraping action;

Start and end points can be set independently. 

The whole process pressure is balanced and stable.

After grinding the scraper or replacing it with a new one, press one key to set and restore the previous printing pressure position.

It completely eliminates the disadvantages of cam mechanical control of squeegee action and ensures that the ink layer and clarity of the image are stable under any printing volume and printing speed. 

6. Screen separation function: 

The screen is separated by electric control to expose the whole conveying table and roller, so as to facilitate the registration of printing parts and the adjustment of feeding materials; at the same time, the cleaning of roller and screen is safer and faster.

7. Electric screen fine-tuning system, remote electric screen three-axis adjustment, direct input adjustment stroke, one step adjustment in place, convenient and practical. 

8. Automatic oiling and lubricating system can reduce chain pulling and noise, and ensure operation accuracy and stability. 

Brief characteristic

Automatic take-off set of screen press and semi-automatic screen printing press are used together, the finished products are caught up and taken out from the printing plate by manipulator and suction mouth, and delivery to next process(drying、solidifying or collecting).It can not only save the manpower, but also improve the using efficiency of the semi-automatic machine. It is fit for screen printing with soft materials, such as paper.
