Inverted-V-shaped clamping plate device of film blowing machine

Abstract

The invention relates to an inverted-V-shaped clamping plate device of a film blowing machine. The device comprises an inverted-V-shaped plate formed by two supporting plates with connected ends. The connected position of the ends of the two supporting plates is provided with a transverse rod capable of being movably connected with the connected position. The transverse rod is provided with a traction roller used for traction of a film. A plurality of guide rollers for sliding of the film are embedded into the middles of the supporting plates and can freely slide through guide roller shafts arranged on the supporting plates. The two disconnected ends of the supporting plates are provided with sliding rolling wheels. The inclined angle of the inverted-V-shaped plate is adjusted through sliding of the sliding rolling wheels. Due to the fact that the guide rollers are in rolling friction with the contact face of a film product, friction acting force on the film is small, damage to the film is reduced, accordingly, the film product quality is improved, the roller distance is enlarged, friction coefficients are greatly reduced, the heat dissipation space is enlarged, the cost is reduced, and installation and maintenance are more convenient.

Description

technical field [0001] The invention relates to a plastic film blowing machine, in particular to a herringbone splint device for a film blowing machine. Background technique [0002] In the actual production of the plastic film blowing unit, the film is under the action of the herringbone board, and the force is complicated. There are differences in the performance of different materials and different process formulas. The folding quality of the film is related to the shape of the herringbone board and the working surface. The quality is related, the smaller the angle between the two gables, the better the surface quality of the film, therefore, reducing the frictional resistance of the gables on the film is the key to ensure the quality of the film. [0003] The plastic film blowing unit is mainly composed of extruder, mold, traction device, secondary traction speed control device, and coiler. The traction device is composed of pinch roller, transmission part, herringbone p...

Problems solved by technology

However, most of the herringbone boards in the prior art are fixed and shaped devices. For different film blowing machines, different herringbone splints are required, which is not conducive to product optimization and maximum effect. In addition, the design of wooden boards is used. The surface of the slats is rough, the heat dissipation performance is poor, and the friction coefficient with the film is large. The additives precipitated by the film are easy to accumulate on the surface of the plate, causing scratches on the surface of the film and affecting the quality of the film.
