A digital printing machine pressing roller device for convenient adjustment of extrusion spacing

Abstract

The invention discloses a pressing roller device for a digital printing machine which is convenient for adjusting the extrusion spacing, comprising a bearing platform, a first motor, a limit mechanism, a second motor, an electric water inlet valve and an electric water outlet valve. The bottom of the bearing platform is connected to the groove, the front side of the bearing platform is fixed with a hot air blower, the air supply channel is fixed on the right side wall of the groove, and the right side of the hot air blower is provided with a second set of The inner top of the moving frame is slidably connected with a slider, and the right side of the digital printing machine is provided with an electric heating plate. The digital printing machine press roller device, which is convenient to adjust the extrusion spacing, after the cloth is placed, the ash sticking cylinder moves down, which is convenient to adjust the distance between the ash sticking cylinder and the bearing platform according to the thickness of the cloth, until the ash sticking cylinder is close to the cloth. When the cloth moves to the right, the sticking cylinder rotates counterclockwise, which is convenient for flattening the cloth, and can stick the dust on the upper surface of the cloth to ensure the cleanliness of the upper surface of the cloth.

Description

technical field [0001] The invention relates to the related technical field of digital printing machines, in particular to a pressing roller device of a digital printing machine which can conveniently adjust the extrusion spacing. Background technique [0002] At present, the printing machines in the prior art are mainly divided into: thermal transfer printing machines, digital printing machines (universal printers) flat screen printing machines, rotary screen printing machines, table printing machines, etc. Digital printing machines are an industry of large-format printers For example, the plotter is similar in the field of CAD. Its ink characteristics are water-based dispersion ink, which is printed on the transfer paper and then transferred to the cloth through high temperature. It is mainly used in the printing and dyeing of clothing fabrics. First, the textile material is flattened by the pressing roller, which is convenient for printing processing. The pressing roller ...

Problems solved by technology

[0003] The object of the present invention is to provide a digital printing machine nip roller device that is convenient to adjust the extrusion distance, to solve the problem that the existing digital printing machine nip roller device proposed in the above background technology is inconvenient according to the cloth before the cloth is printed. Adjust the distance between the nip roller and the upper surface of the bearing table, and the function of the nip roller is relatively simple, which is inconvenient to stick and remove the dust on the surface of the cloth, and at the same time it is difficult to automatically roll up the processed cloth
