Description

Technical Field

[0001] This utility model relates to the field of foaming machine technology, specifically to a foam removal device and a foaming machine for use in foaming machines. Background Technology

[0002] A foaming machine, also known as a foam generator, is a device that produces foam by dissolving a foaming agent in an aqueous solution of a certain concentration. After use, foam residue accumulates inside the foaming machine. To ensure its normal operation, cleaning agent needs to be injected into the machine and cleaned using a foam removal device. However, existing foam removal devices have certain drawbacks. Announcement No. CN217514403U discloses a polyurethane foaming machine, comprising a polyurethane foaming machine body, a top cover movably mounted on the upper surface of the polyurethane foaming machine body, a resistance wire installed in the inner cavity of the polyurethane foaming machine body, and a rotating rod movably sleeved on the inner wall of the top cover, located inside the polyurethane foaming machine body. This utility model, through the cooperation between the polyurethane foaming machine body, a stirring device, and a rubber scraper, utilizes the rotation of the rubber scraper to scrape off material adhering to the inner wall of the polyurethane foaming machine body, achieving an anti-sticking effect on the inner wall of the polyurethane foaming machine body. This effectively solves the problem of material sticking to the inner wall of the polyurethane foaming machine body during stirring. The use of a rubber scraper for cleaning avoids material waste caused by difficulty in falling off the inner wall of the polyurethane foaming machine body, and the timely scraping off of material improves material utilization.

[0003] In the aforementioned document, when the rubber scraper is not in use, the servo motor needs to be started to drive the fixed rod and connecting rod to stir and mix the foaming raw material and foaming additive. At this time, the rubber scraper and the polyurethane foaming machine body will rub against each other, causing unnecessary wear. Based on this, a foam removal device and a foaming machine for foaming machines are proposed to solve the above problems. Utility Model Content

The servo geared motor b703 is started by the servo controller to drive the vertical shaft 704 to rotate. The vertical shaft 704 drives the spur gear 705 to rotate. The spur gear 705 pushes the two sets of meshing toothed plates 706 on the outside to slide, thereby driving the support arm 702 to slide. This causes the rubber scraper 803 to abut against or move away from the inner wall of the foaming machine body 1, thereby reducing wear.
