[0003] When the roll film is wound, it often causes the roll film to relax during the transmission process due to the inconsistency of the two processes before and after, resulting in overlapping and wrinkling of the roll film, which affects the production quality of the roll film. The existing roll film The tensioning device is relatively simple, and can only drive the tensioning roller to jack up or squeeze down to adjust the tension force, resulting in a mediocre tensioning effect, which cannot meet the needs of production, and there is no film feeding device and The film output device affects the flatness of the roll film

The invention discloses a tensioning device for coiled type film winding. The tensioning device for coiled type film winding comprises a worktable, supporting feet are arranged at the bottom of the worktable, and a first winding device, a first tensioning device, a second tensioning device, a third tensioning device and a second winding device are fixed to the worktable in sequence. According to the tensioning device for coiled type film winding, the first tensioning device jacks a coil type film upward, the second tensioning device extrudes the coil type film downward, and the tension force of the coil type film can be conveniently and quickly adjusted; and meanwhile, the third tensioning device is arranged before film discharging, compared with the first tensioning device and the secondtensioning device, a third cylinder in the third tensioning device drives a third tensioning roller to obliquely move upward, the speed of the vertical displacement of the third tensioning roller is slow, the tension force can be adjusted slightly before film discharging, and a ideal effect is achieved. The first winding device and the second winding device are arranged, film feeding and discharging are arranged in front of the tensioning devices to ensure the consistency before tensioning and the smoothness of the film after tensioning, and the production quality is improved.
Description
technical field [0001] The invention relates to a tensioning device, in particular to a tensioning device for roll film winding. Background technique [0002] Rolled membrane, also known as wound membrane element, also known as spiral wound membrane element. It was first developed in the mid-1960s by Gulf General Atomics of the United States under the funding of the Bureau of Salt Water for the application of seawater desalination. It is another type of flat membrane. [0003] When the roll film is wound, it often causes the roll film to relax during the transmission process due to the inconsistency of the two processes before and after, resulting in overlapping and wrinkling of the roll film, which affects the production quality of the roll film. The existing roll film The tensioning device is relatively simple, and can only drive the tensioning roller to jack up or squeeze down to adjust the tension force, resulting in a mediocre tensioning effect, which cannot meet the ...
