Bag smoothing assembly of packaging machine suitable for inner and outer separation type packaging bags

Abstract

The invention discloses a bag smoothing assembly of a packaging machine suitable for inner and outer separation type packaging bags. The bag smoothing assembly comprises a bracket, wherein a lifting assembly is arranged above the bracket, an elastic bag smoothing mechanism is connected below the bracket through a tension adjusting assembly, a telescopic connecting mechanism is also arranged in thebracket, an exhaust pipe is arranged above the telescopic connecting mechanism and at the top of the bracket, a bag opening combination plate is arranged below the telescopic connecting mechanism, and the bag opening combination plate and the elastic bag smoothing mechanism jointly open bag openings. The bag smoothing assembly has the beneficial effects that the action range of a frame can be adjusted through the elastic bag smoothing mechanism, and the bag smoothing assembly is conveniently suitable for different types of packaging bags; a spring pressing plate and the bag opening combination plate can jointly open inner bag openings and can jointly straighten the inner bag openings upwards; and the lifting assembly comprises a pulley lifting mechanism and an air cylinder lifting mechanism, stable up-down movement of the bracket is achieved, and the packaging bags are prevented from being damaged due to overlarge acting force when the air cylinder lifting mechanism is started and stopped instantly.

Description

technical field [0001] The invention belongs to the technical field of automatic packaging of packaging bags, and in particular relates to a bag smoothing assembly of a packaging machine that is suitable for separating the inside and outside of the packaging bag. Background technique [0002] In recent years, industries such as feed and food have experienced unprecedented high-speed growth. However, with the rising costs of raw materials, logistics, marketing, and manpower, domestic and foreign requirements for energy conservation and environmental protection have increased, and industrial grouping, scale, and internationalization With the acceleration of the process, enterprises in industries such as feed and food are facing the challenges of cost control and product upgrading. [0003] In modern industry, automation in the production process has become a prominent theme, and the level of automation in all walks of life is getting higher and higher. Food, etc., most produc...

Problems solved by technology

[0003] In modern industry, automation in the production process has become a prominent theme, and the level of automation in all walks of life is getting higher and higher. Food, etc., most production lines cannot solve the packaging of inner and outer separation

After the material is put into the inner bag, the opening of the inner bag needs to be manually smoothed, and then the inner bag is manually tied, and then the outer bag is sewn with the outer bag folding and sewing equipment. The labor intensity of the workers is high, the rate of work-related accidents is high, and the efficiency is low. , increasing production and management costs in industries such as feed and food
