Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As Figure 1-3, a kind of cooling device for BOPP film production of the present utility model, comprise cylinder type hollow roll body 1 and two bracing frames 2, described hollow roll body 1 two ends support respectively by bracing frame 2, two bracing frames 2 are equipped with water delivery assembly, described water delivery assembly comprises water-supply-pipe 3 and swivel joint 4, and described swivel joint 4 is single direction rotation joint 4.
The two ends of described hollow roll body 1 are provided with reservoir 1-2, and described hollow roll body 1 two ends are connected with the swivel joint 4 on two bracing frames 2 respectively by rotating shaft 5, and described rotating shaft 5 one end is communicated with reservoir 1-2, and rotating shaft 5 other end is communicated with water-supply-pipe 3; Be provided with in described hollow roll body 1 along the axially extended through hole 1-1 of roll body, through hole 1-1 is uniform along roll body circumference.Described through hole 1-1 is communicated with the reservoir 1-2 at described hollow roll body 1 two ends.
Each bracing frame 2 is equipped with a mounting groove 6, tension force Control Component is provided with in described mounting groove 6, described tension force Control Component comprises rise assembly and lowers assembly, described rise assembly comprises upper holder block 7 and the first groups of springs 8, described downward assembly comprises lower lock block 9 and the second groups of springs 10, described upper holder block 7 and lower lock block 9 all has semicircular indentations 11, upper holder block 7 and lower lock block 9 position relatively and after split the breach of upper holder block 7 and the breach of lower lock block 9 form the circumferential notch identical with rotating shaft 5 size, described rotating shaft 5 is located in described circumferential notch, first groups of springs 8 one end is against upper holder block 7, first groups of springs 8 other end is against the upper bottom portion 6-1 of mounting groove 6, second groups of springs 10 one end is against lower lock block 9, second groups of springs 10 other end is against the lower bottom part 6-2 of mounting groove 6.
