4results about How to "Effective tension" patented technology

This invention relates to the field of textile processing technology, specifically to an easily adjustable dyeing and rolling machine, comprising a dyeing vat body and two tensioning parts. The two tensioning parts are respectively located on the outside of the inlet and the outside of the outlet of the dyeing vat body. Each tensioning part includes a drive roller assembly, a tensioning seat, and an adjusting part. A connecting seat is provided on the outside of the dyeing vat body, and the tensioning seat is slidably connected to the connecting seat. The tensioning seat is located between the drive roller assembly and the dyeing vat body. The adjusting part is connected to the side of the tensioning seat adjacent to the drive roller assembly. The fabric is tensioned by the two tensioning parts, facilitating efficient dyeing of the fabric inside the dyeing vat body. The efficient tensioning of the fabric by the adjusting part also facilitates adjustment of the fabric's folds, wrinkles, etc., ensuring efficient dyeing and rolling of the fabric and improving the dyeing and rolling effect.

The utility model discloses a composite device for film layer relates to composite device technical field, including the bottom plate, install two first support board on the bottom plate, two first support board between the common rotation installation has two membrane roll, install second support board on the bottom plate of membrane roll one side, and the opposite face of second support board all is equipped with the sliding slot, and the inside sliding of two sliding slots is installed with two sliding blocks, install the mounting plate on second support board, and the bottom plate below the lower end of mounting plate and mounting plate all are installed with first electric push rod, and the opposite end of two first electric push rod is connected with sliding block respectively, and the common installation has first tensioning adjusting roller between two sliding blocks of same level. The utility model discloses through the control two first electric push rod respectively drive two sliding blocks to move relatively, and two tensioning adjusting rollers are in different positions under the drive of sliding block, and it is convenient to two different thin films of two different materials to be in suitable tension, and it is convenient to carry out the composite operation, effectively avoids the wrinkle of thin film.

This invention discloses a tension control device for conveying plastic film in packaging bag processing, relating to the field of plastic film conveying technology. The second tension control structure of this invention includes a power conveying control unit, which is present in addition to the first tension control structure. The first tension control structure includes a first base frame, a first lower conveying roller unit, and a first upper pressure roller unit. The first lower conveying roller unit includes an angle adjustment mounting box, an angle adjustment lower roller frame, an angle adjustment upper roller frame, a lower roller assembly, and an upper roller assembly. The second tension control structure includes a second base frame, a second lower conveying roller unit, and a second upper pressure roller unit. This invention uses the first tension control structure to adjust the traction force when the plastic film is pulled, while the second tension control structure can provide both conveying speed and pulling force, thereby achieving tension control and solving the problems of low tension control accuracy and inability to adjust tension in a timely manner when the conveying speed changes in existing methods.

This utility model relates to the field of garment processing technology and discloses a flattening device for handling wrinkles in garment fabrics. It solves the problem that existing garment fabric printing devices cannot effectively flatten the fabric before printing, causing wrinkles to affect the printing effect and reduce printing quality. The device includes a worktable, with a support frame fixedly installed on one side of the top of the worktable. Support legs are fixedly installed at both ends of the bottom of the worktable. A pneumatic push rod is fixedly installed on the top of the support frame. The transmission end of the pneumatic push rod passes downward through the support frame and is fixedly installed with a connector. Insert rods are fixedly installed on both sides of the connector via connecting strips. Insertion holes are opened on both sides of the top of the support frame, and two insert rods are slidably installed inside the two insertion holes. A printing machine is fixedly installed at the bottom of the connector. This garment fabric printing device can effectively flatten the fabric before printing, avoiding wrinkles from affecting the printing effect, thereby improving printing quality.
