Problems solved by technology
[0005] The present invention can solve the problem of poor gluing effect, uneven smearing, and easy occurrence of missing coating when gluing the existing woven cloth, and when the woven cloth after gluing is compounded with kraft paper, the kraft paper is not preheated. It leads to problems such as unstable bonding between kraft paper and woven cloth, and prone to falling off.

Embodiment Construction
[0038] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0039] Such as Figure 1 to Figure 6 As shown, a woven bag includes a woven layer 11, an adhesive layer 12, and an inner lining layer 13. The lower end of the woven layer 11 is provided with an adhesive layer 12, and the lower end of the adhesive layer 12 is provided with an inner lining layer 13. The lining layer 13 and the braided layer 11 are connected by an adhesive layer 12.
[0040] In this woven bag production process, in addition to the commonly used circular looms and printing machines, it also involves the above-mentioned special gluing machine for woven bags. The special gluing machine for woven bags includes a bottom plate 2, a gluing device 3, and a bonding machine. In the device 4, a gluing device 3 is installed on the left side of the upp...

The invention relates to a woven bag and a preparation process thereof. The woven bag comprises a woven layer, a bonded layer and an inner lining layer. The invention also provides a glue coating machine for the woven bag, and the glue coating machine comprises a bottom plate, a glue coating device and a bonding device, wherein the glue coating device is installed on the left of the upper end of the bottom plate, the bonding device is installed on the right of the upper end of the bottom plate, and the bonding device is arranged on the right of the glue coating device. The following problems can be solved that when a woven bag in the prior art is coated with glue, a poor gluing effect, uneven coating and easy leakage of coating are generated, and when coated woven fabric is compounded withkraft paper, unstable bonding of the kraft paper with the woven fabric and easy falling off are caused because the kraft paper is not pre-heated; and a good glue coating effect is achieved, materialscraping can be performed by using a glue spreader on the inner end of material discharging holes, and meanwhile the advantage that the phenomenon of blockage caused by solidification of glue liquid can be avoided is achieved through the functions of heating and stirring.
Description
Technical field [0001] The invention relates to the field of woven bags, in particular to a woven bag and a preparation process thereof. Background technique [0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging products. The raw materials are generally polyethylene, polypropylene and other chemical plastic materials. Plastic woven bags are composed of polypropylene bags and polyethylene bags according to the main materials; according to the sewing method, they are divided into seamed bottom bags and seamed bottom bags. At present, woven bags are widely used as packaging materials for fertilizers and chemical products. Since the development of woven bags, the products have developed rapidly, and a series of products with various varieties and complete specifications and sizes have been formed. [0003] At present, the existing woven bags usually have the following defects in the production and processing process: 1. When gluing the woven c...
