Scraper device

Abstract

The invention discloses a scraper device which comprises a drum (1) and scraper blades (2), wherein at least two knife slits are uniformly and symmetrically arranged on the circumference of the drum (1), the scraper blades (2) are arranged in the knife slits, and distance adjustors (3) are arranged in the knife slits and used for adjusting the distance from the tip of each scraper blade to the drum surface. The scraper device solves the problems in the prior art that the scraper is deformed during welding, the scraper which is welded with only one blade is biased, the welded scraper is deformed during the machining process and the knife is polished after being worn and a new knife is welded; and enables the blades to be changed only by dismounting the screws. The process and the structure are more reasonable, the operation is more convenient, and the manufacturing cost is reduced.

Description

[0001] technical field [0002] The invention relates to a scraper used for cutting and stripping film on a rubber scraper of a rubber mixing machine, in particular to a scraper device. [0003] Background technique [0004] The scraper device is used for cutting and stripping the rubber material by the scraping plate on the rubber mixing machine, such as figure 1 and figure 2 As shown, the original scraper structure uses a welded structure. The deformation caused by welding and the weight caused by asymmetry make the blade constantly swing during the process of cutting and stripping the rubber, resulting in instability of the cut film; in manufacturing, the welding seam Large length, asymmetric distribution, resulting in uneven thermal stress, poor welding stability, resulting in a large deformation, this deformation in the further mechanical processing, the uneven stress is continuously released, resulting in deformation while processing; in use In terms of cost and co...

[0004] The scraper device is used for cutting and stripping the rubber material by the scraping plate on the rubber mixing machine, such as figure 1 and figure 2 As shown, the original scraper structure uses a welded structure. The deformation caused by welding and the weight caused by asymmetry make the blade constantly swing during the process of cutting and stripping the rubber, resulting in instability of the cut film; in manufacturing, the welding seam Large length, asymmetric distribution, resulting in uneven thermal stress, poor welding stability, resulting in a large deformation, this deformation in the further mechanical processing, the uneven stress is continuously released, resulting in deformation while processing; in use In terms of cost and cost, if the original scraper device is used, the blade needs to be polished and re-welded after the tool is worn out, and problems such as deformation will reappear, and it is troublesome to disassemble and replace, and the manufacturing cost is high
