Technical Field
[0001] This utility model relates to the field of gauze rolls, and in particular to an automatic gauze roll feeding and flexible unwinding composite device. Background Technology
[0002] In the existing technology, after the gauze roll is produced by the loom, it needs to be cleaned, degreased, and bleached through a bleaching process. Before bleaching, the gauze roll needs to be unwound and rewound on the rolling machine to rewound the gauze roll into a gauze roll that is suitable for the specifications required for bleaching, so as to facilitate the subsequent bleaching process.
[0003] The feeding of gauze rolls is usually done manually. Because gauze rolls are relatively large and heavy, the labor intensity for workers is quite high during handling. If the gauze rolls are long and have a large diameter, multiple people may be needed to handle and feed them, resulting in low efficiency and high labor intensity. Regarding unwinding, traditional equipment has a limited unwinding function, only capable of processing one type of gauze roll. To accommodate multiple lengths or both full-width and split-width rolls, multiple machines are needed. Furthermore, the development of an automatic feeding and unwinding composite device for gauze rolls is still in its infancy in China. Based on these pain points, an automatic feeding and flexible unwinding composite device for gauze rolls is proposed. Utility Model Content

The platform rises to the designated position under the pneumatic lifting device. The operator then pushes the gauze roll into the gap between the two unwinding rollers. After the gauze roll is threaded along the preset path, the unwinding start button is pressed. The floating pressure roller descends to elastically compress the gauze roll, ensuring it is compressed without being crushed, thus preventing difficulty in unwinding. The two unwinding rollers begin to rotate in the same direction under the drive of the geared motor. The unwinding roller rotates the fabric roll through friction to achieve unwinding. When the fabric roll is about to be completely unwound, the tail yarn of the fabric roll is placed on the platform of the hot melt sewing head device, and the head yarn of the next fabric roll is also placed on the platform. Press the hot melt sewing head start button, and the cylinder drives the sewing head device to descend. The hot melt sewing head device contacts the fabric and heats it to sew them together. After sewing is completed, the pneumatic lifting mechanism drives the sewing head device to rise back to its original position. The start button is pressed manually to start the next cycle.

Detailed Implementation
[0026] This application provides an automatic feeding and flexible unwinding composite device for gauze rolls, solving the problem that in the prior art, gauze roll feeding is often done manually. Because gauze rolls are relatively large and heavy, the labor intensity for workers during handling is high. If the gauze rolls are long and have a large diameter, multiple people may be needed to handle and feed them, resulting in low efficiency and high labor intensity.

Fixing the hot-melt seam head 504 and the gauze platform 505; fixing bracket 501 is fixed to the transmission box 6; the gauze platform 505 is set on the fixing bracket 501; fixing the hot-melt seam head 504 is embedded in the gauze platform 505; the third cylinder 502 is installed on the fixing bracket 501, and its piston rod is connected to the lifting hot-melt seam head 503 and corresponds vertically to the fixing hot-melt seam head 504; the transmission box 6 includes a box 601, a reduction motor 602, a drive sprocket 603, a driven sprocket 604, a tensioning wheel 605 and two sets of unwinding rollers 606; the reduction motor 602 is installed on the box 601; the two sets of unwinding rollers 606 are arranged in parallel, one of which is connected to the driven sprocket 604; the drive sprocket 603 is installed on the output shaft of the reduction motor 602;The chain wraps around the drive sprocket 603, the driven sprocket 604, and the tensioner 605.
[0030] The axial spacing of the partition 202 is adjustable, and its number can be increased or decreased according to the number of gauze rolls.
[0031] In the elastic pressure roller assembly 406, the pressure spring 4063 is symmetrically arranged in the up-down movement direction of the pressure roller 4064, so that the pressure roller 4064 forms a floating pressing structure.
[0032] In the length adjustment device 3, rotating the handwheel 304 drives the lead screw 303 to rotate, which in turn drives the two side baffles 302 to move synchronously towards or away from each other to adapt to gauze rolls of different lengths.
[0033] The unwinding roller 606 drives the yarn roll to rotate and unwind through the friction of the roller surface, and the yarn roll is constrained in the following three-dimensional directions: left and right direction: limited by partition 202 or baffle 302; front and back direction: clamped and limited by two sets of unwinding rollers 606; height direction: floating and pressing and limited by elastic pressure roller 4064.
[0034] When the automatic sewing device 5 is working, the third cylinder 502 drives the lifting heat-melting sewing head 503 to press down, pressing the tail yarn and head yarn of the adjacent gauze roll together on the fixed heat-melting sewing head 504 for heating and welding.

[0037] The hydraulic trolley pushes the gauze roll to be processed to the platform 103. The operator pushes the gauze roll onto the platform 103 and moves the pneumatic control valve handle to the start position. The platform 103 rises to the designated position under the drive of the pneumatic lifting device. At this time, the operator pushes the gauze roll into the gap between the two unwinding rollers 606.
[0038] After the yarn roll is threaded along the preset threading route, pressing the unwinding start button causes the floating pressure roller 4064 to descend and elastically press the yarn roll, ensuring it is pressed firmly but not so tightly as to make unwinding difficult. The two unwinding rollers 606 begin to rotate in the same direction under the drive of the geared motor 602. The unwinding rollers 606 rotate the yarn roll through friction, thus achieving unwinding.
[0039] When the gauze roll is about to unwind completely, place the tail yarn of the gauze roll on the platform of the heat-sealing device, and at the same time place the head yarn of the next gauze roll on the platform as well. Press the heat-sealing start button, and the cylinder drives the sewing device to descend. The heat-sealing device contacts the gauze and heats it to sew them together. After sewing is completed, the pneumatic lifting mechanism drives the sewing device to rise back to its original position. Manually press the start button to start the next cycle.
