Abstract
The utility model discloses a flattening roller of a blow molding machine. The flattening roller comprises a roller shaft and a straight roller which is movably connected to the roller shaft, wherein the surface of the straight roller is provided with a plurality of holes. The flattening roller with holes on the surface is adopted, so that harmful friction force between the roller and a film is reduced, materials are saved, and cost is reduced.
Description
Technical field
The utility model relates to a kind of nip rolls, especially relates to a kind of nip rolls that is used for blow moulding machine.
Background technology
Existing plastic products nowadays are widely used in every field by people, and like packaging for foodstuff, fertilizer packaging, booth thermal insulation etc., blow moulding machine and annex thereof are exactly the machine of producing the polybag of various models; The nip rolls that wherein is used on the blow moulding machine is an important composition, and its function is exactly to let the smooth moulding of polybag of processing, and the nip rolls that present people use on blow moulding machine adopts roller mostly; Surfacing; To different types of film, the roll bending degree that requires during flattening is different, and adaptability is bad; And the frictional force between roller and the film is bigger, is unfavorable for guaranteeing the integrity degree of film.
Summary of the invention
The purpose of the utility model just provides a kind of blow moulding machine nip rolls that reduces the harmful frictional force between straight roller and the film.
The technical scheme that the utility model adopts is: a kind of nip rolls of blow moulding machine, and it comprises roll shaft, is movably connected in the straight roller on the roll shaft, and it is characterized in that has plurality of holes on the surface of straight roller.
Above-mentioned roll shaft is solid steel pipe.Above-mentioned straight roller is a plastic roller.
The beneficial effect of the utility model is to adopt the surface to have the nip rolls of hole, reduces the harmful frictional force between roller and the film, and has saved material, and cost is minimized.
Description of drawings
Fig. 1 is the utility model sketch map.
The specific embodiment
As shown in Figure 1; A kind of nip rolls of blow moulding machine, it comprises roll shaft 3, is movably connected in the straight roller 1 on the roll shaft 3, on the surface of straight roller 1 plurality of holes 2 is arranged; Roll shaft 3 can be solid steel pipe or other corrosion-resistant material, and said straight roller 1 can be plastics or other resilient material.The film that blows out when blow moulding machine is during through above-mentioned nip rolls, because the contact area between film and the roller diminishes, harmful frictional force also just reduces thereupon.
Claims (3)
1. the nip rolls of a blow moulding machine is characterized in that it comprises roll shaft (3), is movably connected in the straight roller (1) on the roll shaft (3), has plurality of holes (2) on the surface of said straight roller (1).
2. the nip rolls of a kind of blow moulding machine as claimed in claim 1 is characterized in that described roll shaft (3) is solid steel pipe.
3. according to claim 1 or claim 2 a kind of nip rolls of blow moulding machine is characterized in that said straight roller (1) is a plastic roller.
