Technical field:

The invention relates to a rotary screen printing machine, in particular to a color paste stirring device for a rotary screen printing machine.

Background technique:

The rotary screen printing machine is a major equipment for textile printing. It mainly uses the rotary screen to perform pure rolling on the fabric, and then prints the color paste on the textile through scraping or magnetic rod device, and forms certain patterns and colors. , thus completing the entire printing process.

For some special patterns, because the pattern area on the same cylinder varies greatly, the dyeing amount of the color paste is different for different pattern areas, and the flow velocity of the color paste at the junction of the pattern in the cylinder is not consistent. The storage capacity of the color paste in the length direction of the cylinder will be uneven, and the color printed on the fabric will easily form uneven color stripes at the junction of the pattern, which is commonly called "white stripes". The existing color paste stirring device has a complex structure, and it is not easy to stir the color paste evenly through the movement of the stirring rod alone, resulting in low printing quality, so it is necessary to improve it.

In view of the above-mentioned defects, the designer actively researches and innovates, in order to create a new type of rotary screen printing machine color paste mixing device, so that it has more industrial value.

As a preference of the above scheme, the agitating devices of the two adjacent cylinders are connected to the same rotating screw through corresponding transmission shafts.

As a preference of the above scheme, the bevel gears connected to the drive shafts of two adjacent cylinders are arranged on both sides of one end of the same rotating screw.

As a preference of the above solution, the stirring screw is a horizontal rod extending into the cylinder.

As a preference of the above scheme, the stirring screw rod and the transmission shaft connected thereto are arranged vertically.

As a preference of the above solution, the transmission shaft and the rotating screw rod connected thereto are arranged vertically.

As a preference of the above solution, the motor is connected to a controller.

By means of the above scheme, the present invention has at least the following advantages: the color paste stirring device of the rotary screen printing machine provided by the present invention, because the stirring device composed of the stirring screw rod and the moving block is arranged in the rotary screen, the power device provides power, through The connecting device transmits power to the stirring device, the stirring screw continuously rotates and drives the moving block to move back and forth, and the color paste is stirred by double actions, so that the color paste is more uniform in the circular screen; the device has a compact structure and can effectively ensure the color paste stirring Uniform, improve printing quality.

The above description is only an overview of the technical solutions of the present invention. In order to understand the technical means of the present invention more clearly and implement them according to the contents of the description, the preferred embodiments of the present invention and accompanying drawings are described in detail below.

Description of drawings:
