Embodiment Construction

[0019] The self-setting device of the heat-shrinkable film blowing machine includes a frame, and setting rollers 1 installed side by side on the frame. There are at least five setting rollers 1, and the second one from left to right is a driven roller 1.2. The rest are driving rollers 1.1, 1.3, 1.4..., driving rollers 1.1, 1.3, 1.4... are driven by gears meshed with motors, and the shaping roller 1 includes a roller body 1.1.1 and two side sealing end plates 1.1.2 , the end plates 1.1.2 on both sides are respectively provided with a water inlet hole 1.1.5 and a water outlet hole 1.1.6, which communicate with the spiral groove 1.1.4 provided inside the roller body 1.1.1 to form a spiral flow channel. The water inlet 1.1.5 and the water outlet 1.1.6 are connected to the shaft head 1.1.3 with a central hole, and the shaft head 1.1.3 is connected to the rotary joint and the hose.

[0020] The shaping roller 1 is the roller body 1.1.1 is Q235 steel plate, the surface is plated with...

Abstract

The invention discloses a self-shaping device of a film blowing machine set of thermal shrinkage films and relates to a plastic processing machine. The self-shaping device comprises a rack and shaping rollers which are mounted on the rack and arranged in parallel; at least five shaping rollers are arranged; the second shaping roller counting from left to right is a driven roller; other shaping rollers are driving rollers; gears are arranged on the driving rollers and meshed with a motor, so that the driving rollers are driven by the motor; spiral grooves are formed in roller bodies of the shaping rollers; water inlet holes and water outlet holes are formed in the sealed ends; the inner parts of the water inlet holes and the water outlet holes are communicated with a spiral runner which is formed by the spiral grooves; the outer parts of the water inlet holes and the water outlet holes are connected with rotary joints and flexible pipes. The blown thermal shrinkage films subjected to on-line shaping are low in natural shrinkage and high in shrinkage starting temperature; in particular, the blown thermal shrinkage films have the balanced shrinkage performance and do not need to be shaped by a drying chamber again, so that the blown thermal shrinkage films can be cut and subsequently can be subjected to printing and the like or directly used.

Description

technical field [0001] The invention belongs to plastic processing machinery, in particular to a self-setting device of a heat-shrinkable film blowing unit. Background technique [0002] As a kind of functional film, heat shrinkable film not only has the protection and packaging functions of general plastic films, but also relies on its heat shrinkage function to realize product skin packaging, highlight the characteristics and image of packaged products, and can be used through design, printing Colorful patterns further enrich the packaging and publicity effects. Therefore, it is widely used in the packaging fields of convenience food, beverages, daily necessities, electronic appliances and some industrial products. [0003] According to the production method, the heat shrinkable film is divided into two types: flat film and cylindrical film. The flat film is processed by casting or calendering, and then drawing the film to shape it. The tube film adopts the blown film pr...
