A device for adjusting the magnetic force of a printing magnetic table by adjusting the screw and the cylinder element

Abstract

The invention discloses a device for adjusting the magnetic force of a printing magnetic table in cooperation with an adjusting screw and a cylinder element, which comprises a cylinder element installed at the bottom of a magnetic table support body and a rocker arm pivotally connected to the magnetic table support body; the bottom of the rocker arm The end is connected with the central axis of the cylinder element through double clevis, and the top of the rocker arm is connected with the magnetic table. The magnetic adjustment device also includes a gear set installed on the outer wall of the side beam, a transmission rod connected with the driving gear in the gear set, and an adjusting screw connected with the driven gear in the gear set; one end of the adjusting screw is screwed on the driven gear In the threaded hole, the other end is connected to the bottom end of the double clevis through an anti-wear device. Through the above-mentioned technical solution, a small adjustment force applied to the transmission rod from the outside can drive the adjustment screw to retreat or advance through the gear set, and the anti-wear device can transmit the power to the rocker arm without contacting the adjustment screw with the double clevis. Then the central axis is stretched or retracted to accurately and effectively adjust the magnetic force of the magnetic table.

Description

Technical field: [0001] The invention relates to the technical field of rotary screen printing machines, in particular to a device for adjusting the magnetic force of a printing magnetic table by adjusting the cooperation of a screw rod and a cylinder element. Background technique: [0002] The scraping device of the rotary screen printing machine is divided into two types: blade scraping and magnetic bar scraping. Blade scraping is to apply pressure through the elasticity of the stainless steel blade itself. The characteristic of printing is that the scraping lines are relatively clear, but the variety and width of fabrics are limited, and it is not suitable for thick and wide fabrics. Magnetic rod scraping printing is to put a steel rod in the rotary screen, and a row of magnets are arranged under the fabric. The steel rod is attracted by the magnet to exert pressure on the color paste to complete the printing. The line definition of magnetic bar scraping printing is slig...
