Thermoplastic film cutting device for adhesive tape packaging

Abstract

The invention relates to a thermoplastic film cutting device for adhesive tape packaging. The thermoplastic film cutting device comprises a hot air cutter. Fixing plates are arranged on the two sides of the hot air cutter correspondingly and provided with a plurality of stand columns arranged below the fixing plates. The stand columns are provided with sliding blocks capable of sliding. A spring is arranged between each stand column and the corresponding sliding block. Each sliding block is provided with a first connecting rod and a second connecting rod which are parallel to each other, wherein one end of the first connecting rod and one end of the second connecting rod are hinged to the sliding block, the first connecting rod is provided with a vertical rod located between the hot air cutter and the sliding block, the two ends of the vertical rod are hinged to the other end of the first connecting rod and the other end of the second connecting rod, and the vertical rod is provided with an oblique rod arranged below the vertical rod. The multiple oblique rods arranged on the same side of the hot air cutter are connected through a pressing plate located below the oblique rods. Torsion springs are arranged at the hinged parts of the first connecting rods and the sliding blocks, and the sliding blocks are provided with limiting blocks. The hot air cutter is provided with a plurality of stirring rods corresponding to the sliding blocks. The second connecting rods are provided with stop rods arranged below the stirring rods. The thermoplastic film cutting device is ingenious in structure, the cutting process is stable and continuous, and cut thermoplastic film notches are tidy.

Description

technical field [0001] The invention relates to the technical field of tape packaging equipment, in particular to a thermoplastic film cutting device for tape packaging. Background technique [0002] In the tape packaging process, it is usually necessary to pack individual tape rolls first, and then pack a certain number of multiple tape rolls; the current tape packaging process has basically been automated, so when performing roll packaging, Multiple tape rolls are sent to the packaging table by the conveying equipment and stacked, and then the thermoplastic film is wound; because the thermoplastic film is mostly made of rolls of raw materials, in order to make the packaging process easier to achieve, two rolls of thermoplastic film are usually Introduce into the packaging equipment from the upper and lower sides respectively and connect the ends of the introduction. When the bundle is pushed to this position, the upper and lower parts of the thermoplastic film wrap the bun...

Problems solved by technology

[0003] Although this method has been widely used in the industry, there are still some defects. In general, in order to make the thermoplastic film as flat as possible during cutting and ensure the neat cutting position, it is usually necessary to customize or modify the hot air knife, that is, Install flat plates on both sides of the hot air outlet, so that when the hot air knife moves down, the two sides of the incision of the thermoplastic film can be pressed against the packaging table by the flat plate, so that the thermoplastic film can be aligned smoothly; however, because the work of the hot air knife mainly depends on high temperature Airflow, for the sake of safety, the knife holder material is made of metal, and the plates installed on both sides are also made of metal, so as to avoid deformation or potential safety hazard caused by poor heat resistance of the material; Good heat resistance, but due to its excellent thermal conductivity, after a period of use, after heat transfer, the temperature of the knife holder of the hot air knife and the plates installed on both sides rises rapidly, and the thermoplastic film is cut When the flat plate is pressed on the thermoplastic film or is close to the thermoplastic film, the thermoplastic film will be thermally deformed, which not only affects the neatness of the incision position, but also affects the aesthetics of the thermoplastic tape packaging, thus affecting the overall quality of the product. Quality and Sales Positioning

[0004] At present, this problem can only be solved by replacing the hot air knives. Therefore, in continuous production operations, it is necessary to prepare multiple hot air knives as spare parts, which increases the equipment cost, and the replacement of the hot air knives is relatively cumbersome. After the replacement, the air duct must be replaced again. Connect and ensure that it is well sealed, which requires higher requirements for operators
