Problems solved by technology

[0002] At present, many bag film packaging machines in China do not have longitudinal seal preheating devices. When thick bag film is used or the packaging machine runs at a relatively fast speed, the longitudinal seal marks are prone to damage, unevenness or loose sealing, which reduces the packaging capacity. The qualified rate of production caused a lot of unnecessary waste

Abstract

The invention discloses a vertical sealing preheating device. The vertical sealing preheating device is characterized by comprising a fixing plate, an opening and closing mechanism and a heating mechanism, wherein the opening and closing mechanism is mounted on the fixing plate and used for opening and closing a heating mechanism, and the heating mechanism is mounted at the lower end of the opening and closing mechanism and used for preheating bag films. The heating mechanism can be opened and closed through the opening and closing mechanism. Bag films of a packing machine can be preheated through the heating mechanism. The vertical sealing preheating device is simple and compact in structure and is mounted on the bag film packing machine. By adopting the vertical sealing preheating device, the bag films can be preheated before vertical sealing, so that vertical sealing marks are smoother and more attractive, and the qualified rate of packing production is increased.

Description

technical field [0001] The invention discloses a longitudinal sealing preheating device, which belongs to the field of packaging machinery. Background technique [0002] At present, many bag film packaging machines in China do not have longitudinal seal preheating devices. When thick bag film is used or the packaging machine runs at a relatively fast speed, the longitudinal seal marks are prone to damage, unevenness or loose sealing, which reduces the packaging capacity. The qualified rate of production caused a lot of unnecessary waste. Contents of the invention [0003] The purpose of the present invention is to provide a longitudinal sealing preheating device, which can preheat the bag film before longitudinal sealing, make the longitudinal sealing marks more smooth and beautiful, and improve the qualified rate of packaging production. [0004] The technical solution of the present invention is: a longitudinal sealing preheating device, which is characterized in that i...
