Embodiment Construction

[0020] The details and working principles of the implementation modes and examples of the present invention will be described below with reference to the accompanying drawings. This kind of sealing mechanism includes a sealing and cutting device and a conveying device. A sealing and cooling device is provided in front of the sealing and cutting device. The working positions of the sealing and cutting device and the sealing and cooling device are respectively a sealing and cutting station and a sealing and cooling station; Device is prior art, comprises the sealing cutter 2 that lifts up and down and the following knife 18 that cooperates with sealing cutter, and described sealing cooling device includes upper cooling plate 8; The cooling of the sealing position of bag body on described upper cooling plate can be Air-cooling or water-cooling is used. For thin bags, the effect of air-cooling is better, that is, the upper cooling plate 8 is provided with blowing holes 9, and the b...

Abstract

The invention discloses a sealing mechanism which comprises a sealing and cutting device and a conveying device. The sealing mechanism is characterized in that a seal cooling device is arranged in front of the sealing and cutting device, and the seal cooling device comprises an upper cooling plate; the conveying device comprises an upper conveyor belt and a lower conveyor belt, the upper conveyorbelt and the lower conveyor belt are arranged in front of the sealing and cutting device, and the upper cooling plate is arranged on a conveying path of the upper conveyor belt. The upper cooling plate cools a sealed part, so that the sealing part of a bag body is cooled quickly and kept level. A cooled sealing line is not adhered to the bag body, so that the bag body is prevented from being damaged during use, and therefore, the quality of the bag body is improved. The upper cooling plate is arranged on the conveying path of the upper conveyor belt, so that conveyance of the bag body is not affected and the cooling effect is also achieved.

Description

technical field [0001] The invention relates to an improved invention of a sealing mechanism, in particular to a bottom sealing mechanism or a side sealing mechanism of a plastic bag. Background technique [0002] Wrinkles will occur after bottom sealing or side sealing of the plastic bag body, and the finished bags after bottom sealing or side sealing are stacked directly, because the sealing line is still hot, the sealing line of the upper and lower bag bodies will stick during stacking, wait until When in use, the bag body is separated, and the adhesive part of the bag body is easily torn. Contents of the invention [0003] In view of the technical problems in the background technology, the technical problem to be solved by the present invention is to provide a sealing mechanism, which can make the sealing line smooth, improve the quality of the bag body, and avoid the bag body from sticking. [0004] In order to solve the above-mentioned technical problems, the presen...
