Description

Technical Field

[0001] The utility model relates to the technical field of tape casting machines, in particular to a side material recovery mechanism for tape casting machines. Background Art

[0002] Casting machine refers to special equipment for making cast film. High-precision electronic ceramic casting machine uses alumina as the main raw material for ceramic casting. First, the crushed powder is mixed with binder, plasticizer, dispersant and solvent to make a slurry with a certain viscosity. The slurry flows down from the hopper and is scraped and pressed by a scraper to a certain thickness on a special base belt. After drying and curing, it is peeled off from the top to become a film of green tape. Then, according to the size and shape of the finished product, the green tape is punched, laminated and processed to make a finished blank to be sintered. It has the advantages of low cost, high quality, non-toxicity and simple production process. In the existing production process, a large amount of waste edge materials are often generated, and the accumulation of waste materials is not convenient for collection.

[0003] In response to the above problem, a Chinese patent announcement with announcement number CN213201934U discloses a winding film casting machine with a side material recovery mechanism, and its technical key points are: including a casting machine equipment body, a box body, a translation assembly and a winding assembly. The support plate is slidably connected to a moving part, and the moving part is screwed to the screw rod. A telescopic part is arranged between the two semi-cylinders, and the movable end of the telescopic part is hinged to one end of the connecting rod.

[0004] In actual operation, it was found that the above scheme still has at least the following defects: the device is not convenient for simultaneously winding up the two waste edges generated by cutting the film, which easily causes the waste edges to pull the uncut film on the cast-film machine toward the middle, causing the film to twist and deform. For this reason, we propose a cast-film machine edge material recovery mechanism to solve the above problem. Utility Model Content
