Problems solved by technology

The defect of the current above-mentioned structure is that the ink is pumped from the ink pump to the ink tank by means of the ink delivery tube. However, due to the large pumping volume of the existing ink, the ink volume at the outlet of the ink delivery tube is large. In turn, the ink enters the ink tank with a relatively large initial velocity, and finally produces air bubbles
In addition, when the inking roller rotates at high speed in the ink, a large number of air bubbles will also be generated
The above-mentioned bubbles are attached to the inking roller, and even the doctor blade cannot completely remove them, and the improper operation of the doctor blade will also cause scratches to the inking roller; if the bubbles accumulate for a long time, the printed product will produce patterns, causing A lot of printed matter is scrapped

Embodiment Construction

[0028] For ease of understanding, the specific structure and working method of the present invention are described as follows in conjunction with the accompanying drawings:

[0029] When the inking roller b works, it is actually as figure 1 Only part of the roller is shown below the ink level. When the inking roller b rotates and inks, first figure 1 The right side of the roller surface enters the ink, and this entry side is the ink inlet side of the ink roller b; similarly, when the ink roller b continues to rotate, the roller surface below the ink liquid surface will continue to move and bring out the ink , and then cooperate with the embossing roller at the main machine of the extruder to realize the ink coating function on the film die surface. And the tank wall of the side of the ink tank a that is relatively close to the dancer roller 10 is actually the tank wall where the ink separation assembly 30 is placed, that is, figure 1 The right tank wall shown is the side wh...

Abstract

The invention belongs to the field of film printing equipment, and particularly relates to a bubble isolating device for an extrusion machine ink groove. The bubble isolating device at least comprisesa floating roller floating on ink liquid surface in a groove cavity of the ink groove; the floating roller is arranged on the ink inlet side of an ink feeding roller; the axial direction of the floating roller is parallel to the axial direction of the ink feeding roller; the roller face of the floating roller abuts against the roller face of the ink feeding roller; the abutting face, relative tothe roller face of the floating roller, of the ink feeding roller forms a matching face of matched with a to-be-printed film; and the roller length of the floating roller is greater than or equal to the film width of the to-be-printed film. Bubbles in the ink groove can be effectively isolated, and thus the extrusion yield of the film is ensured.

Description

technical field [0001] The invention belongs to the field of film printing equipment, and in particular relates to a bubble isolation device for an ink tank of an extruder. Background technique [0002] Extrusion compounding machine is a laminating composite device that can complete the extrusion and compounding of multi-layer composite materials in one process. It is widely used in various flexible packaging industries such as paper, cloth, BOPP film, liquid milk filling, and pharmaceutical packaging. . The extrusion machine needs to go through the ink coating process when extruding the film that needs to be colored. In actual operation, insert the ink fountain cart with the inking roller into the socket reserved on the extruder, and rely on the inking roller to form a roller surface fit with the embossing roller on the extruder host. Afterwards, the film to be colored is pasted and passed through the gap between the above two rollers. During the advancing process of the ...
