Description
Technical Field
The application relates to the field of thermoplastic film production and processing equipment, in particular to a thermoplastic film rolling mechanism with a flattening function.
Background
Thermoplastic films are used for the marketing and transportation of various products, the primary function of which is to stabilize, cover and protect the product. The thermoplastic film has high puncture resistance, good shrinkage and certain shrinkage stress. The thermoplastic film has wide application, can not generate holes in the thermoplastic film in the shrinkage process of the thermoplastic film, and is convenient to use.
The production process of the thermoplastic film comprises the steps of formulation, mixing, granulating, extruding thick films, air cooling, boiling water heating in a hot water bath, transverse blowing-up in a shaping cylinder, bubble quenching by a film clamping roller and rolling into the thermoplastic film. In the process of winding into the thermoplastic film, the tension of the thermoplastic film is unstable, and when the thermoplastic film is wound on a material collecting tray, the thermoplastic film is easy to form folds, so that the surface of the thermoplastic film wound on the material collecting tray is uneven, and the quality of the thermoplastic film is affected.
Disclosure of Invention
The application aims to provide a thermoplastic film rolling mechanism with a flattening function, which can smooth wrinkles when a thermoplastic film is wound.
The thermoplastic film winding mechanism with the flattening function comprises a support, a motor is mounted on the support, a receiving tray is mounted on an output shaft of the motor, a flattening supporting block is arranged below the receiving tray, an arc-shaped groove matched with the outer edge of the receiving tray and used for flattening a thermoplastic film is formed in the top end of the flattening supporting block, a pressure spring is connected to the lower end of the flattening supporting block, the pressure spring is connected to the lower end of the support, a scale is fixed on the support, adjacent flattening supporting blocks of the scale are arranged, zero scale marks of the scale are located on the top end of the scale, and the lowest part of the outer edge of the receiving tray is flush with the zero scale marks of the scale when the thermoplastic film is not wound.
The operating principle and the beneficial effect of this scheme are, when coiling thermoplastic film on receiving the charging tray, the motor drives and receives the charging tray and rotate, thermoplastic film is received the charging tray and is rotated the in-process and is coiled on receiving the charging tray, make the thermoplastic film thickness on the charging tray increase gradually, the thermoplastic film thickness increases the back and applies pressure for flattening supporting the piece, make flattening supporting piece downwardly moving and compress the pressure spring, represent the thickness that thermoplastic film was coiled through the scale value that the lowest end corresponds of thermoplastic film reel, quantitatively coil thermoplastic film, avoid thermoplastic film to coil too much and make the product overweight inconvenient transportation.
When the thermoplastic film is wound on the material receiving disc for a circle, each layer of thermoplastic film is stroked by the arc-shaped groove of the flattening supporting block due to clearance fit between the arc-shaped groove of the flattening supporting block and the bottom end of the material receiving disc, and the flattening supporting block butts the thermoplastic film for stroking, so that the thermoplastic film is prevented from forming folds when being wound, and the quality of the thermoplastic film is prevented from being influenced.
Further, a soft film is arranged on the arc surface of the arc-shaped groove.
When the arc-shaped groove spreads the thermoplastic film on the material collecting disc, the soft film is stuck on the surface of the thermoplastic film, and the spreading block is not in direct contact with the thermoplastic film, so that the thermoplastic film is prevented from being spread by the spreading block during rolling, and the quality of the thermoplastic film after rolling is ensured.
Further, a plurality of strip-shaped convex columns are arranged on the soft film and are parallel to the central shaft of the material receiving disc.
In the process that the thermoplastic film is wound on the material receiving disc, the material receiving disc rotates to enable the plurality of protruding columns to smooth the winding of the thermoplastic film in sequence, the plurality of protruding columns can smooth the thermoplastic film for a plurality of times, wrinkles are avoided when the thermoplastic film is wound on the material receiving disc, and the quality of the thermoplastic film after being wound is guaranteed.
Further, an air bag which can be pressed by the pressure spring is arranged at the lower end of the pressure spring, and a hose which blows out air from the soft film is connected to the air bag.
In the process of winding the thermoplastic film on the material receiving disc, the thickness of the thermoplastic film on the material receiving disc is gradually increased, because the arc-shaped groove of the flattening abutting block is in clearance fit with the material receiving disc, the thermoplastic film downwards presses the flattening abutting block, the pressure spring transfers the received pressure to the air bag, the pressure extrudes air in the air bag from the hose to the soft film, and the soft film and the thermoplastic film are prevented from being stuck together when the thermoplastic film is flattened.
Further, a through hole capable of blowing air to the material collecting disc is formed in the soft film, an air passage communicated with the through hole is formed in the flattening supporting block, and the soft tube is communicated with the air passage.
In the process of downwards extruding the air bag by the pressure spring, air is extruded between the soft film and the thermoplastic film from the air bag, so that the soft film is prevented from being attached to the thermoplastic film, and the flattening supporting block is not prevented from moving downwards.
Further, the bottom of the arc-shaped groove and the zero scale line of the scale are positioned on the same horizontal line.
When the flattening block is pressed against and moves downwards due to the increase of the thickness of the thermoplastic film, the thickness of the coiled thermoplastic film can be intuitively known from the scale value on the scale, and errors caused by manual measurement are reduced.
