Fully-automatic method for horizontally injecting hot melt adhesive and adhesive-injecting machine thereof

Abstract

The invention discloses a fully-automatic method for horizontally injecting a hot melt adhesive and an adhesive-injecting machine thereof. The fully-automatic method for horizontally injecting the hot melt adhesive comprises the following steps of horizontally placing a product, driving the product to rotate by a servo motor, injecting the adhesive to the product in the vertical direction, cooling the hot melt adhesive on the surface of the product by low-temperature compressed air, after adhesive injection is finished, while horizontally conveying the product, keeping rotating the product, and cooling the hot melt adhesive on the surface of the product again by cold air. The adhesive-injecting machine comprises a rotary feeding mechanism, a servo driving rotating mechanism, an adhesive injection cooling mechanism, a rotary conveying mechanism and a cold air blowing mechanism. The problems of adhesive dripping, adhesive breaking and adhesive accumulation of the product are effectively solved, meanwhile, unmanned operation can be realized, the requirement on fully-automatic online production of different products is met, the processing cost is reduced, and the production efficiency is improved. Furthermore, the adhesive-injecting machine has the functions of production data acquisition, data storage and the like, so that the management and control of a production enterprise on a production and processing process are facilitated.

Description

technical field [0001] The invention relates to a glue injection method, in particular to a fully automatic horizontal glue injection method for hot melt glue and a glue injection machine. Background technique [0002] Filters are widely used in the automobile manufacturing industry, mainly including air filters and oil filters, which are used to filter impurities in the air or oil. Filters are wearing parts and need to be replaced periodically. At present, in order to improve the performance and service life of the filter and the stability of the air and oil distribution of the filter in the vehicle system, domestic and foreign automotive filter manufacturers have implemented the method of injecting the filter into the origami interval of the filter paper after the filter is formed. The processing technology of fixed folding distance hot melt adhesive. [0003] In the prior art, there are mainly two processing methods for filter glue injection. One is to place the filter ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there are mainly two processing methods for filter glue injection. One is to place the filter vertically, the drive device drives the vertical rotation, and the glue injection system injects glue horizontally. Because the hot melt glue is in a melting state, Glue dripping, glue breaking, and glue accumulation are the most serious problems for products injected in this way, and the quality of the fixed folding distance of the filter is difficult to guarantee; the other is to place the filter horizontally, and the drive device drives the vertical direction to rotate , the glue injection system injects glue vertically, and after the glue injection is finished, it is transported horizontally by the conveyor line. Although this method is better than the previous one, there are still problems of glue dripping, glue breaking, and accumulation of glue after molding, and the filter cannot be guaranteed. quality of folding distance

In addition, the existing hot melt glue injection machines can only meet the production needs of a single product. For different types of glue injection products, corresponding specific glue injection machines are required, which increases the corresponding cost for the production of enterprises.

[0004] Generally speaking, the current processing of filter glue injection mainly has the problems of glue dripping, glue breaking, uneven glue injection, low production efficiency (12 pieces / minute), and the products after glue injection still cannot reach the filter fixed The purpose of the folding distance, and a glue injection machine can only meet the glue injection needs of a single product
