In the process of moving products or raw materials on the conveyor belt, it can adversely affect the base of the composite belt. Gradual pollution leads to problems. To prevent this, many designs use a scraper for the conveyor. It allows you to effectively clean the tape from raw materials or products. Thus, preventing individual particles from entering the mechanism. Increases its reliability and minimizes the need for unscheduled maintenance.
What are scrapers
As a rule, the working surface of the conveyor has a certain strength. If you apply too much physical force, the tape will wear out quickly and be critically damaged. Quality scrapers must have certain technical characteristics, implemented by the structure of the material:
- The correct physical dimensions for a particular type of conveyor.
- The scraper for primary, rough cleaning can be made of steel.
- Products for additional, fine cleaning are made of relatively soft polymers.
- The presence of an additional steel insert is required to combat wear.
- Products must perform their functions at any speed of the belt.
The main technical function of the scraper is to prevent loose raw materials from entering between the belt and the drive drum. In this case, the abrasive will lead to rapid wear of the flexible part of the conveyor. After installing the element, it must be properly adjusted so that it performs its work as accurately as possible on the conveyor equipment.
Features of modern scrapers
Manufacturers can make scrapers from different materials. Each has its advantages and disadvantages. But, as practice has shown, the best in terms of quality of work and wear resistance is a special rubber. It has a minimal negative effect on the composite main conveyor belt. Other benefits of rubber include the following factors:
- predictable flexibility over a wide range of operations
- it is possible to additionally fix the metal bar;
- the rubber component remains flexible in the summer heat and in the winter cold;
- as it wears, its position relative to the conveyor can be adjusted;
- will never allow an emergency stop of the conveyor belt;
- relatively inexpensive when replacing worn parts.
The scraper plays an important role in the normal operation of technological equipment. The Noria brand to buy will be the right decision, as the part minimizes the loss of raw materials during its movement by the tape. Guarantees preservation of the mechanism in a working condition. Does not require frequent adjustments and replacement due to wear.
