Description

Technical Field

[0001] The utility model relates to the technical field of gravure printing, in particular to a device for removing bubbles of gravure printing ink. Background Art

[0002] The traditional gravure printing machine is an ink immersion gravure printing machine, which includes a gravure printing roller and a back roller. The gravure printing roller is immersed in an ink tank containing ink, and a back roller is arranged above the gravure printing roller. As the gravure printing roller rotates, the ink in the ink tank is brought up and printed on the surface of the substrate.

[0003] However, this kind of ink immersion gravure printing machine is prone to stirring the ink in the ink tank and generating bubbles during the rotation of the gravure printing roller. The bubbles are mixed in the ink and adhere to the surface of the gravure printing roller. They are easy to enter the mesh holes on the surface of the gravure printing roller, causing insufficient or uneven ink application on the mesh holes, resulting in differences in printing color, which seriously affects the printing quality. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a device for removing bubbles from gravure printing ink. By means of a sleeve-positioning rod, an inner ring-connecting rod, and an outer ring-connecting rod combined structure, a user can use rollers of different diameters to contact the sleeve during operation. The outer side wall of the roller will press the sleeve structure in a vertical direction. Since the inner ring and the outer ring are sleeved on both sides of the positioning rod, when the inner rod moves inward, the spring structure in the positioning frame can be stretched by the connecting rods on the upper and lower sides to play a buffering role. The spring offsets the pressure from the sleeve through its own deformation, thereby maintaining the sleeve in close contact with the side wall of the roller. By setting a spring on the inner side of the outer frame There are multiple groups of extrusion components. When the internal roller is rotating, four groups of extrusion components can cover half of the area of ​​the roller, thereby improving the actual use effect of removing bubbles, meeting the requirements of on-site use, and improving the printing effect. Through the set roller-extrusion component structure, the user can fix rollers of different sizes in the outer frame in actual operation, and contact the side wall of the roller through the outer driving device. During the rotation of the roller, the roller is tangent to the positioning rod, so that the roller drives the sleeve to rotate, and squeezes out the bubbles in the ink between the roller and the sleeve, as well as the bubbles attached to the surface of the roller, so that the ink is evenly filled in the mesh holes on the surface of the roller, avoiding printing color differences and ensuring printing quality.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a device for removing bubbles from gravure printing ink, comprising an outer frame, a roller is arranged inside the outer frame, an extrusion assembly is arranged on the inner wall of the outer frame, the extrusion assembly comprises a positioning frame fixed to the inner wall of the outer frame, a sleeve arranged on the inner side of the positioning frame, a positioning rod sleeved in the sleeve, an inner ring and an outer ring arranged on one side of the positioning rod, a group of inner rings and outer rings are arranged on both sides of the positioning rod, the inner rings on both sides and the outer rings on both sides are connected and fixed by connecting rods, a spring is arranged in the positioning frame, and the two ends of the spring are respectively fixedly connected to the inner walls of the two groups of connecting rods.

[0006] As a preferred technical solution of the utility model, the sleeve is a hollow rod structure, and the positioning rod is guided in the sleeve, and anti-slip rings are fixed on both sides of the positioning rod.

[0007] As a preferred technical solution of the utility model, both ends of each group of connecting rods are fixed on the outer side wall of the inner ring, and both the inner ring and the outer ring are hollow circular ring structures.

[0008] As a preferred technical solution of the utility model, the connecting rods of the two groups of inner rings are placed at the top end of the positioning frame, and the connecting rods of the two groups of outer rings are placed at the bottom end of the positioning frame.

[0009] As a preferred technical solution of the utility model, the outer side wall of the sleeve is in contact with the outer side wall of the roller shaft, and the inner ring and the outer ring on both sides of the sleeve are placed on both sides of the roller shaft.

[0010] As a preferred technical solution of the utility model, four groups of extrusion components are symmetrically arranged on the inner side wall of the outer frame.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] 1. In this device, through the roller-extrusion assembly structure, the user can fix rollers of different sizes in the outer frame in actual operation, and contact the side wall of the roller through the outer driving device. During the rotation of the roller, the roller is tangent to the positioning rod, so that the roller drives the sleeve to rotate, and squeezes out the bubbles in the ink between the roller and the sleeve, as well as the bubbles attached to the surface of the roller, so that the ink is evenly filled in the mesh on the surface of the roller, avoiding the difference in printing color and ensuring the printing quality.
