CN201881538U - Combined foam stabilizing ring for plastic film production - Google Patents

Abstract

The utility model discloses a combined foam stabilizing ring for plastic film production, which consists of a circular connecting plate (1) and middle-layer foam stabilizing roll support blocks (2), wherein the middle-layer foam stabilizing roll support blocks (2) are vertically fixed at the inner side of the circular connecting plate (1) with equal distances; and a middle-layer foam stabilizing roll (5) is fixed between neighboring middle-layer foam stabilizing roll support blocks (2). The combined foam stabilizing ring for plastic film production is characterized in that an upper-layer foam stabilizing roll (4) and a lower-layer foam stabilizing roll (6) are fixed on the inner side of the circular connecting plate (1) through lengthened support blocks (3); the upper-layer foam stabilizing roll and the lower layer foam stabilizing roll (4 and 6) are staggered with the middle-layer foam stabilizing rolls (5) on the vertical direction; and the layer surfaces of the upper-layer foam stabilizing roll, the middle-layer foam stabilizing rolls and the lower-layer foam stabilizing roll (4, 5 and 6) are mutually parallel. The combined foam stabilizing ring for plastic film production stabilizes foams by staggering the three layers of foam stabilizing rolls, so that clearance does not exist in stabilizing the foams and the foams are stabilized into round shapes without break angles, therefore, the foam stabilizing effect is greatly improved, and the production quality of films can be improved.

Description

Plastic sheeting production is surely steeped ring with combined type

Technical field

The utility model relates to the improvement that a kind of plastic sheeting is extruded steady bubble ring in the operation, and specifically a kind of plastic sheeting production is surely steeped ring with combined type.

Background technology

Steady bubble ring is to be applied to the vitals that plastic sheeting is extruded, and is enclosed within the outside of film bubble, and the operation that film is steeped plays stabilization.Present employed steady bubble ring, by annular connecting plate, back-up block, connecting axle, surely steep roller and constitute, steady bubble roller is established one deck, establish the 5-8 root in one deck and surely steep roller, the connecting axle of every steady bubble roller is fixed on the inboard of annular connecting plate by corresponding back-up block, makes it become the polygon that is arranged in the aspect.The deficiency that the steady bubble ring of this single layer structure exists is: because every steady bubble roller is straight roller, be arranged in the aspect, be in polygonal shape on the outer periphery of film bubble, the head of its adjacent steady bubble roller, tail joint form knuckle, the film bubble also forms knuckle at this knuckle place, so the stablizing effect to the film bubble is undesirable, particularly in the production process of high-grade bottom blowing type packaging film, individual layer surely steeps ring makes the product of producing not reach standard-required.

Summary of the invention

The purpose of this utility model is to provide a kind of film is steeped to carry out three layers of staggered steady bubble, and the plastic sheeting production that can avoid film to bubble out existing knuckle, raising steady bubble effect and performance is surely steeped ring with combined type.

For reaching above purpose, the technical scheme that the utility model adopted is: this plastic sheeting production is surely steeped ring with combined type, surely steeping the roller back-up block by annular connecting plate and middle level constitutes, it is equidistant that the roller back-up block is surely steeped in the middle level, be vertically fixed on the inboard of annular connecting plate, adjacent middle level surely steep between the roller back-up block fixing on the middle level surely steep roller, it is characterized in that in the inboard of annular connecting plate fixing by the lengthening back-up block on the upper strata surely steep roller and roller surely steeps in lower floor, on, lower floor surely steeps roller and middle level and surely steeps roller and be staggered in vertical direction, on, in, the place aspect that roller surely steeps in lower floor is parallel to each other, make the film bubble stabilize to circle, no knuckle is to improve steady bubble effect.The utility model is also implemented by following measure: surely steep in the roller at the upper, middle and lower layer, establish the 5-8 root for every layer and surely steep roller, equidistantly be arranged in the aspect, the connecting axle that every of roller steady bubble roller is surely steeped in the middle level all is fixed on corresponding middle level and surely steeps on the roller back-up block, and surely steep the roller back-up block by corresponding middle level and be fixed on the annular connecting plate, the connecting axle of the steady bubble roller of upper and lower alignment all is fixed on the same lengthening back-up block in the steady bubble of upper and lower layer roller, and lengthening back-up block and middle level are surely steeped the roller back-up block and be spaced.

The beneficial effects of the utility model are: surely steep ring with the individual layer of present use and compare, by three layers of staggered steady bubble, make steady bubble not have the gap, the film bubble is stablized circular, no knuckle, thus steady bubble effect is increased substantially, can improve the quality of production of film.

The specific embodiment

Make the utility model with reference to accompanying drawing 1,2.This plastic sheeting production is surely steeped ring with combined type, surely steeping roller back-up block 2 by annular connecting plate 1 and middle level constitutes, the inboard that roller back-up block 2 is equidistant, be vertically fixed on annular connecting plate 1 is surely steeped in the middle level, adjacent middle level surely steep between the roller back-up block 2 fixing on the middle level surely steep roller 5, it is characterized in that in the inboard of annular connecting plate 1 fixing by lengthening back-up block 3 on the upper strata surely steep roller 4 and roller 6 surely steeps in lower floor, upper and lower layer steady bubble roller 4,6 and middle level are surely steeped roller 5 and are staggered in vertical direction, and the place aspect that the upper, middle and lower layer surely steeps roller 4,5,6 is parallel to each other.Surely steep in the roller 4,5,6 at the upper, middle and lower layer, establish the 5-8 root for every layer and surely steep roller, equidistantly be arranged in the aspect, the connecting axle 7 that every of roller 5 steady bubble roller is surely steeped in the middle level all is fixed on corresponding middle level and surely steeps on the roller back-up block 2, and surely steep roller back-up block 2 by corresponding middle level and be fixed on the annular connecting plate 1, the connecting axle 8,8 of the steady bubble roller of upper and lower alignment in the steady bubble of upper and lower layer roller 4,6 ' be separately fixed at the upper and lower end of same lengthening back-up block 3, lengthening back-up block 3 surely steeps roller back-up block 2 with the middle level and is spaced.
