TECHNICAL FIELD
[0001] The utility model relates to a novel wine bottle inner wall drawing equipment technical field, concretely relates to a glass bottle bottom inner wall arc drawing device. BACKGROUND
[0002] In recent years, in order to meet consumer demand, various glass bottle designs emerge in endlessly. Usually, patterns or graphics are drawn on the outer surface of the bottle body, so that the bottle body has both practicality and artistry. In order to improve the artistry of the bottle body, a glass bottle is launched, which presents patterns through the bottle wall and the liquid in the bottle. This kind of glass bottle needs to draw patterns on the inner wall of the bottle bottom, and the drawing difficulty is relatively large, and the quality of drawing has a great influence on the texture of the glass bottle. Although the existing machine has higher drawing efficiency compared with manual drawing, the precision of the machine in coating the paint on the surface of the bottle body is difficult to control, and usually a template with graphic holes is covered on the bottle body drawing surface to assist graphic drawing, however, the template has poor adhesion with the bottle body, and the paint coated on the surface of the bottle body is easy to flow down along the gap between the sleeve body and the bottle body, so that halo occurs in the area around the hole, which affects the graphic drawing precision.
[0003] In the patent of a novel wine bottle inner wall drawing equipment of our company, by setting the supporting sleeve, the inner bottle body is sleeved outside the supporting sleeve, the flexible outer sleeve body expands under the inflation action of the inflation gap, and is tightly attached to the inner wall of the inner bottle body, so as to reduce the gap between the supporting sleeve and the bottle body, effectively avoid the liquid flowing along the bottle wall surface at the hole during the spraying on the inner wall of the inner bottle body, and cause halo at the drawing edge. However, after the drawing is finished, the gas in the inflation gap is extracted through the air hole by the air inlet and outlet adjusting device, since the air hole is arranged on one side of the flexible outer sleeve body, the gas cannot be extracted synchronously, so the flexible outer sleeve body cannot be synchronously attached to the inner sleeve body, and part of the flexible outer sleeve body is still attached to the inner wall of the bottle bottom groove, which easily causes secondary damage to the pattern formed by the flexible outer sleeve body on the inner wall of the bottle bottom groove during discharging.
