Glue paper sealing machine for carton

Abstract

The invention relates to the technical field of carton processing and discloses a glue paper sealing machine for a carton. The glue paper sealing machine comprises a delivery mechanism, wherein two parallel pressing plates are arranged above the delivery mechanism; a gap is kept between the two pressing plates; a glue tank and a hook rod in rotational connection with a scroll are arranged above the gap; a first guide roller, a second guide roller and a third guide roller are arranged at one side of the hook rod; the glue tank is located between the second guide roller and the third guide roller; a glue applying roller located below paper is in rotational connection with the interior of the glue tank; a cutter is arranged at one side of the third guide roller; a pushing mechanism which pushes the cutter to move up and down is arranged on the upper surfaces of the pressing plates; a fixed plate is vertically arranged at one side of the cutter; a movable plate is hinged to the fixed plate; a paper slip passes through a gap between the fixed plate and the movable plate; and the outer side of the movable plate is connected to the cutter through a connecting rod. According to the glue paper sealing machine, glue is adhered onto one side of the paper slip, and the paper slip is delivered smoothly; and meanwhile, during cutting of the paper slip, a free end of the paper slip is prevented from drawing back.

Description

technical field [0001] The invention relates to the technical field of carton processing, in particular to a carton glue paper sealing machine. Background technique [0002] Carton is one of the most commonly used goods storage tools. According to different materials, it is divided into corrugated cartons, single-layer cardboard boxes, etc. As an indispensable part of modern logistics, cartons bear the importance of packaging, product protection, and aesthetics. After the carton is scrapped, it can also be used as a raw material for papermaking, recycled and remade into paper, which is in line with the modern concept of environmental protection. When the carton is filled with items, the side wings at the bottom of the carton should be sealed. After the carton is filled with items, the side wings at the top of the carton should be sealed. The traditional way to seal the carton is to use plastic tape to adhere to the carton. Because the plastic tape has Strong adhesion, it i...

Problems solved by technology

But there are the following problems in the above scheme: 1, the bottom of the paper strip pressure roller passes through and is completely soaked in the glue tank, so that the two sides of the paper strip all can be adhered with glue, and when the paper strip with glue on both sides passes through the guide roller , the paper strip will stick to the guide roller, making the transmission of the paper strip not smooth

2. When the paper strip adheres to the top of the carton and seals the top side of the carton, after the paper strip is cut with scissors, the free end of the paper strip is likely to retract, so that the paper strip is separated from the guide roller. When using paper strips to seal the carton for the first time, it is necessary to redirect the paper strips, which is troublesome to operate
