Circular screen printer adjusting mechanism adopting magnetic bar printing mechanism

Abstract

The invention discloses a circular screen printer adjusting mechanism adopting a magnetic bar printing mechanism. The circular screen printer adjusting mechanism comprises a rack, support plates are fixed on two side plates below the rack, a magnetic table is fixed on the back of a top plate of the rack, driving motors are fixed on the support plates, output shafts of the driving motors are inserted into holes in the support plates and are fixed with vertical adjusting rods via couplers, and the lower ends of the vertical adjusting rods and the couplers are arranged in the holes. The vertical adjusting rods are inserted into adjusting sleeves, the adjusting sleeves are inserted into through holes of the top plate of the rack, the top ends of the vertical adjusting rods extend out of the adjusting sleeves, the top ends of the vertical adjusting rods are connected with connectors in a threaded manner, and two ends of a nickel screen roller are hinged with the connectors correspondingly. The nickel screen roller can be adjusted up and down so as to be pressed against cloth for printing. Meanwhile, paste discharge amount and speed of a pulp delivery roller can be controlled, and printing effect is ensured.

Description

Technical field: [0001] The invention relates to the technical field of textile equipment, in particular to an adjustment mechanism of a rotary screen printing machine using a magnetic bar scraping mechanism. Background technique: [0002] Rotary screen printing is a printing method that uses a scraper to print the color paste in the rotary screen onto the fabric under pressure. [0003] The printing roller of the existing rotary screen printing machine is generally a nickel mesh roller, the two ends of which are hinged on the bracket, and the nickel mesh roller is pressed against the cloth, and the color paste is squeezed by the scraper in the nickel mesh roller, so that The color paste is printed on the fabric through the nickel mesh roller, and when the thickness of the fabric is different, for example, when the thickness of the fabric becomes thinner, the nickel mesh roller will not completely press against the fabric, thus affecting the printing of the fabric Effect. ...

Problems solved by technology

[0003] The printing roller of the existing rotary screen printing machine is generally a nickel mesh roller, the two ends of which are hinged on the bracket, and the nickel mesh roller is pressed against the cloth, and the color paste is squeezed by the scraper in the nickel mesh roller, so that The color paste is printed on the fabric through the nickel mesh roller, and when the thickness of the fabric is different, for example, when the thickness of the fabric becomes thinner, the nickel mesh roller will not completely press against the fabric, thus affecting the printing of the fabric Effect

[0004] Moreover, there is another way for the rotary screen printing machine to use magnetic rods for extrusion, and the pulp delivery roller is in the nickel mesh roller. The rotation of the magnetic bar and the nickel mesh roller presses the color paste on the cloth through the nickel mesh. There is a gap between the bottom end of the guide plate and the nickel mesh, which makes it easy for part of the slurry to leak from the left side of the magnetic bar. The extrusion of the rod and the leakage directly through the nickel mesh will affect the printing effect. Moreover, the amount and speed of the existing slurry delivery roller can only be controlled by the slurry delivery device connected with the slurry delivery roller. Other methods are Unable to control, single control method, limited control effect
