Tension-adjustable drying device for packaging film processing

Abstract

The invention relates to the technical field of packaging film drying, and discloses a tension-adjustable drying device for packaging film processing. The device comprises a drying box, first bearingblocks are arranged on the left side wall and right side wall of the drying box, a winding roller is rotationally connected to the first bearing block on the left side, a second bearing block is arranged at the top of the drying box, a second driving motor is fixedly connected to the upper portion of the second bearing block, an output shaft of the second driving motor is fixedly connected with adriving disc, the front side of the driving disc is rotationally connected with the upper end of a second supporting rod, and the lower end of the second supporting rod is rotationally connected withthe middle of the upper surface of a second sliding block. According to the tension-adjustable drying device for packaging film processing, a first tension roller and a second tension roller are arranged in the drying box, so that packaging film can be expanded in the drying box; and the second tension roller is driven to continuously move through the second driving motor, and the tension of the packaging film is continuously adjusted, so that local heating deformation of the packaging film is avoided.

Description

technical field [0001] The invention relates to the technical field of packaging film drying, in particular to a tension-adjustable drying device for packaging film processing. Background technique [0002] The packaging film is mainly composed of several different grades of resin mixed and extruded. It is puncture-resistant, super-strength and high-performance. It wraps the goods stacked on the pallet to make the package more stable and tidy, and has a super waterproof effect. It is widely used in foreign trade export, paper making, hardware, plastic chemical industry, building materials, food and medicine industries. [0003] Plastic composite packaging film is a packaging film made of multi-layer films through printing and compounding processes. It is mainly used for the outer packaging of some medium-sized machinery. After the production is completed, it will be rewound and stored by a reel. Moisture will occur due to problems such as sealing and environment. For some s...

[0003] Plastic composite packaging film is a packaging film made of multi-layer films through printing and compounding processes. It is mainly used for the outer packaging of some medium-sized machinery. After the production is completed, it will be rewound and stored by a reel. Moisture will occur due to problems such as sealing and environment. For some special mechanical equipment, the damp plastic composite packaging film needs to be dried before use. However, due to the large number of layers of packaging film, traditional drying devices are not suitable The effect of drying inside the packaging film is not very good, and it takes more time and human resources

[0004] Chinese patent (notification number: CN209639445U) discloses a drying box for processing polylactic acid-starch-PVA composite degradable packaging film, including a drying box, a packaging film and a winding roller. A set of guide rollers, with drying rollers symmetrically distributed between each adjacent group of guide rollers, the two ends of the drying rollers are movably connected to the inner wall of the drying box through a connecting shaft, and the drying rollers are hollow , and the drying roller is provided with a number of uniform and strip-shaped drying holes, the drying roller located between the drying holes is provided with adsorption cotton, and the drying box is provided with a motor on one side, so The output end of the motor is connected to the connecting shaft through the inner wall of the drying box, and the adjacent connecting shafts are connected by a chain. trachea, the air intake pipe is provided with an air inlet pipe that matches the drying roller, and the air inlet pipe communicates with the drying roller through the air inlet pipe, and the upper end of the drying box is provided with an exhaust port, but the packaging of the device The tension of the film cannot be adjusted freely, resulting in mediocre drying effect, so the device needs to be improved
