The invention discloses a forced water-cooled plastic extruding film compounding unit, relates to the technical field of compounding units, and aims to solve the problems of poor cooling effect of the film by the cooling roll of the existing compounding unit and poor deviation correction effect in the film conveying process. The lower end of the broadcasting machine is equipped with an adjustment base, the top of the inside of the adjustment base is provided with a first sliding block, the rear end of the broadcasting machine is provided with a deviation correction device, and the upper end of the deviation correction device is provided with a second sliding block, The upper end of the second sliding block is fixedly provided with a support frame, and a deviation correction roller is installed in rotation between the support frames, a compound machine is installed at the rear end of the deviation correction device, and a cooling roller is installed at the rear end of the compound machine , the inside of the cooling roller is provided with a number of partitions arranged in sequence, and a cooling cavity is formed between the partitions, and a water diversion plate is arranged at the middle position of the cooling cavity, and the cooling cavity is divided by the water diversion plate into Inlet chamber and return chamber.
Description
technical field [0001] The invention relates to the technical field of composite unit, in particular to a forced water-cooled plastic extrusion film composite unit. Background technology [0002] After being plasticized by the screw, the plastic particles are extruded in a linear form from the die mouth of the flat die. After stretching, they are attached to the surface of flexible substrates such as paper, film, non-woven fabric and woven fabric. After cooling and shaping, they can form a composite material with both the barrier and heat sealing of the plastic film layer, the strength, toughness and functional characteristics of the substrate. [0003] However, there are some problems in the use of the existing composite unit: first, the cooling roller can not realize the rapid and effective cooling of the composite film; second, the film is prone to offset in the process of film conveying, and the transmission structure of the commonly used deviation correction device is relati...
