A kraft bag bonding device

Abstract

The invention relates to the technical field of paper bag gluing, in particular to a cattlehide bag bonding device. The cattlehide bag bonding device comprises a conveying mechanism, a glue containing vessel, a gluing wheel, a roller and a stepping motor. The conveying mechanism comprises conveying belts and transmission wheels, and fine holes are formed in the conveying belts. The conveying mechanism is internally provided with a negative pressure mechanism fixed to a rack, and paper slips are adsorbed to the outer surfaces of the conveying belts through the negative pressure mechanism. A guiding wheel is arranged above a second conveying mechanism and comprises a left circumferential wall and a right circumferential wall, and the right circumferential wall of the guiding wheel is detachably connected with a cotton material. The guiding wheel is provided with a cavity, the cavity is internally provided with a proximity transducer and a controller used for controlling the motion state of the first conveying belt, and the proximity transducer, the controller and the stepping motor are connected in series. The glue containing vessel is fixedly connected to the rack, and the gluing wheel is connected into the glue containing vessel in a rolling manner. The roller is in rolling connection to the rack and is located above the first conveying belt. The cattlehide bag bonding device can be used for accurately bonding a seam of a cattlehide bag, and meanwhile dripping glue can be absorbed.

Description

technical field [0001] The invention relates to the technical field of paper bag gluing, in particular to a kraft bag bonding device. Background technique [0002] Kraft bag is a packaging container made of composite materials or pure kraft paper. It has the characteristics of non-toxic, odorless, pollution-free, low-carbon environmental protection and high strength resistance. It is one of the most popular environmentally friendly packaging bags in the world. In the production process of traditional kraft bags, glue is usually attached to the paper strips manually, and then the paper strips are pasted on the seams of the kraft bags. This manual sticking is inefficient and time-consuming and labor-intensive. In order to solve this problem, there is now a line-type gluing device. This gluing device sprays glue onto the paper strips first, and then transfers the paper strips to the seam of the kraft bag for bonding. But this device has the following defects: 1. During the tr...

Problems solved by technology

But this device has the following defects: 1. During the transmission process of the paper strip coated with glue, the glue will drip onto the conveyor belt along the paper strip, and the kraft bag will be pasted on the surface of the conveyor belt, thus causing the kraft bag to be difficult to unload , if external force is used, the kraft bag will be damaged; 2. When the paper strip is sent to the seam, there will be inaccurate seams, which will affect the quality of the kraft bag
