Problems solved by technology

However, in the process of the gear pump conveying the color paste, it is difficult to accurately control the output of the color paste, that is, when the gear pump stops, the color paste remaining in the delivery pipe can continue to flow out under the action of inertia

Abstract

The invention discloses a slurry pump assembly of a fully automatic rotary screen printing machine, which comprises a gear pump, a feed pipeline connected with the gear pump inlet, and a discharge pipeline connected with the gear pump outlet. The discharge pipe is provided with a shut-off device, which includes a rotating shaft pivotally connected in the discharge pipe and perpendicular to the centerline of the discharge pipe, a cut-off plate fixed on the shaft, and a driving mechanism installed on the outer wall of the discharge pipe. In actual operation, a pressure sensor is installed on the cutoff plate. When the gear pump operates and the pressure in the discharge pipeline rises, the pressure sensor senses, and the driving mechanism drives the cutoff plate to rotate 90 degrees accurately to realize the opening of the discharge pipeline; The gear pump is closed, and the driving mechanism drives the cutoff plate to rotate another 90 degrees to realize the sealing of the discharge pipeline, and then accurately control the output of the color paste.

Description

Technical field: [0001] The invention relates to the technical field of textile machinery, in particular to a fully automatic rotary screen printing machine slurry pump assembly. Background technique: [0002] The gear pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gear to deliver or pressurize the liquid. Two closed spaces are composed of two gears, the pump body and the front and rear covers. When the gears rotate, the volume of the space on the side where the gears are disengaged increases from small to large, forming a vacuum to suck the liquid, and the volume of the space on the side where the gears mesh changes from large to large. Small, and the liquid is squeezed into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of two gears. The pressure at the outlet of the gear pump depends entirely on the resistance at the outlet of the pump. ...
