Product Description

1. Structural features

• Automatic feeding system: This part is the key to realize automated production. It usually includes silos, conveyor belts and positioning devices. The silos are used to store a large number of plastic hoses and rubber hoses, and their capacity can be designed according to production needs. The conveyor belt transports the hoses from the silo to the printing station in an orderly manner, and the speed of the conveyor belt can be adjusted to match the printing speed. The positioning device can accurately position the hose at the starting position of printing to ensure that the printing position of each hose is accurate and consistent.

• Printing system:

• Screen printing part: A high-precision screen printing head is used, and the tension and mesh of the screen can be adjusted according to the printing requirements of plastic hoses such as seam hoses. The pattern or text on the screen is made by processes such as photosensitive plate making, which can accurately control the amount of ink penetration, thereby achieving high-quality monochrome printing.

• UV curing system: It is mainly composed of UV lamps and reflective covers. UV lamps can emit ultraviolet rays of a specific wavelength to provide energy for ink curing. The reflective cover focuses the UV light and evenly irradiates it on the printed hose to accelerate the curing of the ink. Compared with the traditional drying method, this UV curing method has the advantages of fast curing speed and strong ink adhesion.

• Body frame and transmission system: The body frame is generally made of solid metal materials to provide stable support for the entire machine. The transmission system includes motors, belts, gears and other components, which are responsible for driving the automatic feeding conveyor belt, the up and down movement and left and right movement of the printing head, etc., to ensure the coordinated operation of various components.

2. Working principle

• The automatic feeding system transports the plastic hose from the silo to the printing station and positions it. The screen printing head descends and squeezes the ink through the mesh of the screen plate onto the surface of the plastic hose to form a pattern or text. After printing, the printing head rises, the UV curing system starts, and the ultraviolet light emitted by the UV lamp irradiates the printed ink, so that the ink cures quickly. The cured plastic hose is sent out of the printing press by the conveyor belt to complete the entire printing process.

3. Scope of application

• Mainly suitable for monochrome printing of various plastic hoses, especially seam hoses. Seam hoses need to be printed with brand logos, product instructions, instructions for use and other information on the surface. This printer is also suitable for other similar plastic hoses, such as single-color printing of cosmetic hoses, pharmaceutical hoses, etc., which can effectively improve the recognition and aesthetics of the product.

4. Operation process

• Preparation: Put the plastic hose into the silo of the automatic feeding system, check whether the screen is installed correctly, whether the ink is sufficient, and whether the UV curing system is working properly. Pour an appropriate amount of ink on the screen, start the machine, and let the ink be evenly distributed on the screen.

• Parameter setting: According to the size, material and printing requirements of the plastic hose, set the speed of automatic feeding, the height of the print head and the printing pressure, the time and intensity of UV curing and other parameters.

• Printing operation: Start the printing process and observe the operation of the automatic feeding system and the printing system. Check whether the printed pattern or text is clear and complete, and adjust the parameters in time if there is any problem. At the same time, pay attention to the UV curing effect to ensure that the ink is completely cured.

• Finish the work: When all plastic hoses are printed, turn off the machine. Clean the screen and print head, and store the remaining ink properly. Perform daily maintenance on the machine, such as cleaning the body and checking the transmission parts.

Summary︰
Plastic hollow containers are widely used in product packaging such as: medicine, cosmetics, detergents, lubricating oil, beverages, daily necessities, and chemical containers. They are generally made of PP, PE PET, PC and other materials by blow molding. More and more large-scale factories use automatic screen printing machines to print their products. Since this kind of screen printing machine is connected like a long queue, it is vividly called a silk screen printing dragon.
Screen printing dragon is the first automatic screen printing machine to enter the market, and it also occupies the largest share in the market. Now it is also the most standardized automatic screen printing machine. Its main structure is:
1) Feeding conveyor belt: It is a conveyor belt. The operator can place the product to be printed on the conveyor belt. The conveyor belt can automatically transfer the plastic bottle to the feeding position, and the feeding nozzle of the machine will suck the bottle To the transfer table of the screen printing machine. Some users will request to customize the automatic feeding chute, and the bottles can be put into the feeding chute, and the bottles will be automatically arranged into the feeding conveyor belt.
2) Pre-press device: The pre-press device includes orientation adjustment of plastic bottles and product surface treatment, such as flame treatment, plasma treatment, coating of PP oxidant, etc.
3) Printing system: The printing system of the automatic screen printing machine is similar to the printing device of the semi-automatic screen printing machine, but it has more functions. In order to improve the printing efficiency and precision, more and more movements of the screen printing device are controlled by servo motors, pneumatic components More and more international famous brands are used for electronic and electronic components, and the main parts of the machine are also processed with high-strength steel instead of aluminum profiles. The wear resistance and service life of steel materials are much better than aluminum profiles.
4) UV drying system and UVLED drying system: For continuous high-speed screen printing, an important option to ensure that the screen is not blocked is to use UV ink, which will basically not dry to the screen surface and affect printing unless it is irradiated by ultraviolet rays.
5) Unloading system: If you do not arrange the printed products, you only need one unloading conveyor belt, but if you need to arrange the printed products, the machine will be equipped with a manipulator and placed regularly on the conveyor belt.
Now more and more users choose automatic multi-color container screen printing machine, which actually integrates three processes of flame treatment, silk screen printing and curing, which not only greatly reduces the labor intensity of the operator, but also greatly improves the printing quality of the product. Factories that are accustomed to semi-automatic screen printing machines have also begun to upgrade and purchase brand new screen printing machines to expand production capacity.
