Gluing device for valve bag production

Abstract

The invention relates to the technical field of valve bag production equipment, in particular to a gluing device for valve bag production, which comprises a support, one end of the support is provided with a discharging roller, the other end of the support is provided with a traction roller, a gluing assembly is arranged between the discharging roller and the traction roller, the gluing assembly comprises a gluing nozzle, and the outside of the gluing nozzle is connected with a storage box. A booster pump is arranged between the material storage box and the gluing nozzle, a pressing roller is arranged on the side, facing the traction roller, of the gluing nozzle, a cleaning scraper is arranged on one side of the pressing roller, materials are transmitted through the discharging roller and the collecting roller on the support, the gluing nozzle is installed in the middle of the support and located above the materials to be glued, the upper surfaces of the materials are coated with glue, and therefore the glue can be sprayed on the upper surfaces of the materials. According to the glue coating device, the glue on the surface of a material is prevented from slipping off after being coated, and the glue is pressed by the compression roller after being coated, so that the adhesion degree of the glue and the surface of the material is increased while the glue is uniformly distributed on the surface of the material, and the production yield of a product is further improved.

Description

technical field [0001] The invention relates to the technical field of valve bag production equipment, in particular to a gluing device for valve bag production. Background technique [0002] Valve bag, commonly known as sticky bottom bag, is an internationally popular packaging bag. It feeds from the top or bottom valve port. It adopts special filling equipment. After filling the material, it is packed into a cube. The stacking is neat and beautiful. It is used to pack food powder, chemical powder, fertilizer, synthetic materials, explosives, food, salt, minerals and other powdery or granular solid materials and flexible items. Compared with traditional woven bag protection, it has good sealing performance and is convenient for stacking. Advantages such as transportation and transportation, the valve bag is used in the production process to press the multi-layer composite structure with mechanical energy. Glue is used to bond and fix the two sides that fit together, and fin...

[0002]Valve bag, commonly known as paste bottom bag, is an international popular packaging bag, feeding from the top or bottom valve port, using special filling equipment, filling materials and then packing into Square body, neatly stacked and beautiful, belongs to the environmental protection bag, mainly used for packing food powder, chemical powder, fertilizer, synthetic materials, explosives, grain, salt, minerals and other powdery or granular solid materials and flexible items. In the traditional woven bag protection, it has the advantages of good sealing, convenient stacking and transportation. In the production process of the valve bag, the multi-layer composite structure is mechanically pressed together, and glue is needed between the two sides of the joint. Carry out bonding and fixing, and finally turn over and shape. The existing valve bag gluing equipment mostly uses concave coating rollers for gluing operations. The rotation of the gluing roller with continuous thread grooves on the instant noodles is applied after the glue is adhered to the surface and the material with gluing is attached. This method can only pass the material from the upper part of the gluing roller ( That is, the glue is applied on the lower surface of the material), when the thickness of the glue is large, it will cause the glue to slip on the lower surface of the material during the transmission of the material, and when the glue is seriously slipped, it will cause the glue coating on the surface of the material to be incomplete. Uniformity, not reaching the thickness required for production, thereby reducing the sound ray efficiency and yield of the product, while the open-type storage box is not sufficiently sealed during operation, and there is a risk of impurities entering, resulting in impurities adhering to the glue Roll on and then fight on the surface of the material or puncture the material, affecting the product yield
