Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a rotating bottle scraping device. Background Technology

[0002] The excipients inside the rotating bottle are easily oxidized and have a certain viscosity. Traditionally, they need to be scraped manually with a stainless steel spatula, which is inefficient and costly.

[0003] Utility model patent application CN115672904A discloses a device for scraping off excipients from thin-walled rotating bottles. It uses a rotation control mechanism to adjust the direction of the scraper mechanism and a scraper control mechanism to control the scraper's scraping action, enabling automatic scraping. However, certain defects were found during use, as follows:

[0004] 1. The rotary control mechanism is connected to the bushing via gear transmission, while the scraper control mechanism is driven by belt and lead screw. The structure is complex, the stability is low, and it is not easy to maintain.

[0005] 2. The gear fixed to the lower end of the scraper holder and the rack fixed to the upper end of the control shaft are exposed. When scraping auxiliary materials, the auxiliary materials can easily enter the connecting seat through the gaps on the connecting seat, which will contaminate the gear fixed to the lower end of the scraper holder and the rack fixed to the upper end of the control shaft. After accumulating to a certain amount, it will cause blockage, affect the use, and be difficult to clean. Utility Model Content
