Title:
CUTTING DEVICE FOR POLYMER FILM PRODUCTION
Document Type and Number:
WIPO Patent Application WO/2021/092909
Kind Code:
A1
Abstract:
A cutting device for polymer film production comprises a support frame (1). A top end of the support frame (1) supports a top plate (2). A telescopic cylinder (3) is fixedly mounted on an upper surface of the top plate (2). An output end of the telescopic cylinder (3) is connected to a transmission rod (4). The transmission rod (4) passes through the interior of the top plate (2). An end of the transmission rod (4) is connected to a connecting seat (5). Outer surfaces of two sides of the connecting seat (5) are each connected to a guide seat (6). A guide rail (7) is fixedly mounted on an inner side of the support frame (1). The guide rail (7) is provided in the guide seat (6). A lower surface of the connecting seat (5) is connected to a cutter (8). A cushioning mechanism (9) is connected at a lower surface of the connecting seat (5) close to an outer side of the cutter (8). The cushioning mechanism (9) consists of a connecting column (901), a cushioning column (902), a position-limiting block (903), a cushioning spring (904), and a cushion (905). The cutting device for polymer film production performs cushioning when the cutting device performs cutting, and enables the cutting device to be laterally fixed.
