Description

Technical Field

[0001] The utility model relates to the field of glue leveling mechanism for foaming in bag production, and more specifically to a glue leveling mechanism for foaming in bag production. Background Art

[0002] When producing bags, it is necessary to attach a foam coating to the surface of the leather fabric. The foam coating is a process in which a foaming agent is added to a high-concentration finishing liquid, and then a foaming device is used to mix it with air to form a certain mass of foam, and then the foam is evenly applied to the surface of the fabric through a foam applicator. A foam adhesive layer is applied to the surface of the fabric, and the coating layer is used to produce flame retardant and anti-fouling properties, and the fabric has a unique style, feel and appearance, good air permeability and low cost;

[0003] Before coating, it is necessary to foam the adhesive first. After foaming, the adhesive is filled with a large number of bubbles. Then, the adhesive is coated on the fabric by a coating machine. When using an existing coating machine for coating, the adhesive is usually poured into the liquid inlet of the coating machine, and then squeezed by the roller of the coating machine to squeeze the adhesive evenly on the fabric. However, in this working process, the adhesive reaches the roller from the same position and is squeezed to be dispersed. During the dispersion process, a large number of bubbles will run out or break, and it is difficult to ensure the retention rate of the bubbles. Therefore, a structure is needed to evenly disperse the adhesive to various places before the adhesive enters the roller to improve the preservation rate of the bubbles.

[0004] In the prior art, such as the authorization announcement number CN218360426U, the utility model provides a bubble adhesive coating and leveling mechanism, which is used in the field of textile production. The main points of the technical solution are: comprising: a shell, a liquid inlet opened on the upper part of the shell for adding adhesive, and a liquid outlet opened on the lower part of the shell for spraying the adhesive to the coating part of the coating machine; a protrusion is provided on an inner wall of the shell near the liquid outlet, and a liquid leveling port is formed between the protrusion and the remaining inner wall of the shell so that the adhesive can flow out evenly; a liquid storage tank for storing adhesive is formed between the protrusion and the inner wall of the shell away from the liquid outlet, and when the adhesive in the liquid storage tank accumulates more than the protrusion, it flows from the liquid leveling port to the liquid outlet; the technical effect is: the adhesive can be dispersed in advance before coating, the bubble breakage during the coating process when the roller squeezes the adhesive is reduced, and the bubble preservation rate is improved;

[0005] In the above-mentioned patent, when applying the glue, it is directly introduced into the roller surface, and its uniformity is poor. The thickness of the glue is uneven when applying, resulting in uneven bonding of the cloth. Utility Model Content
