Description

Technical Field

[0001] This utility model relates to the field of fabric printing and dyeing technology, and in particular to a high-efficiency fabric spreading device for fabric printing and dyeing. Background Technology

[0002] Fabric dyeing and finishing, also known as dyeing and finishing, is a processing method that includes pretreatment, dyeing, printing, finishing, washing, etc. It involves immersing the fabric in a dye bath, where the dye diffuses and fixes onto the fibers through the relative movement of the dye and the fibers.

[0003] Because undyed fabrics are mostly stored in rolls for easy storage and transportation, they need to be unrolled before printing and dyeing. This requires a fabric unrolling machine. The working process of the fabric unrolling machine is roughly to pull out one end of the fabric and use a power device to continuously feed the fabric, thereby continuously unrolling the fabric from the roll.

[0004] Most fabric spreading machines only have the function of spreading out the fabric. During the spreading process, the fabric may bend at an angle, causing the spread fabric to flip or fold, which will affect subsequent processes such as printing that require the fabric to remain flat. Utility Model Content

[0005] To overcome the problem that most fabric spreading machines only have the function of spreading the fabric, the fabric may bend at an angle during the spreading process, causing the spread fabric to flip or fold, which will affect subsequent processes such as printing that require the fabric to be kept flat.

[0006] The technical solution of this utility model is as follows: a high-efficiency fabric spreading device for printing and dyeing, including a spreading frame, spreading rollers and a drive assembly. Spreading rollers are provided on the inner side of the spreading frame and are arranged obliquely. Tensioning seats for tensioning the fabric are provided on both sides of the spreading frame. A fabric roll is provided on one side of a set of tensioning seats. A conveying roller is provided on the inner side of the tensioning seat. A tensioning roller is provided above the tensioning seat. A first motor for driving the conveying roller to rotate is provided on one side of a set of tensioning seats. A third motor for driving the spreading roller to rotate is provided above the spreading frame. A drive assembly is provided at the output end of the third motor. A second motor for driving the spreading frame to move is provided on one side of the spreading frame.

[0007] Preferably, a lifting frame is provided above the tensioning seat, an electric telescopic rod is provided between the lifting frame and the tensioning seat, and a second guide rod is slidably connected at the four corners of the lifting frame.

[0008] Preferably, a spring is provided between the supports at both ends of the tension roller and the lifting frame, and a first guide rod is provided on the inner side of the spring, which is slidably connected to the lifting frame.

[0009] Preferably, the bottom of the flattening frame is provided with a base, and a linear guide rail is provided at the connection between the base and the flattening frame. The output end of the second motor is provided with a threaded screw, and the two ends of the threaded screw have opposite thread directions and are threadedly connected to the flattening frame.

[0010] Preferably, the drive assembly includes pulleys and gears, with gears provided at one end of each of the two sets of flattening rollers, pulleys provided on one side of one set of gears and at the output end of the third motor, and a first transmission belt provided between the two sets of pulleys.

[0011] Preferably, the flattening roller is provided with mounting brackets at both ends and a second drive belt at both ends.

[0012] Preferably, the flattening rollers are arranged in two layers, and the linear velocity of the flattening rollers along the fabric conveying direction is the same as the speed at which the fabric is conveyed.

[0013] The beneficial effects of this utility model are:

[0014] By setting up slanted flattening rollers, the linear speed of the flattening rollers along the fabric conveying direction is consistent with the speed at which the fabric is conveyed during flattening. This causes the flattening rollers to generate an outward pulling force on the edges of the fabric, flattening the folds of the fabric and preventing the fabric from folding during the unfolding process, which would affect the printing and dyeing process.
