Embodiment 1

[0040] see Figure 1-2 , an automatic cloth spreading device for screen printing, comprising a printing platform 1 and a quantitative feeder 2, the printing platform 1 is provided with a spreading mechanism 3, a flatness measuring mechanism 4, a longitudinal flattening mechanism 5, a horizontal flattening mechanism 6 and Controller; printing platform 1 is used to provide a flat surface for printing, quantitative feeder 2 is used to intermittently release a fixed length of cloth; spreading mechanism 3 can be disassembled from printing platform 1, and spreading mechanism 3 is used for the first feeding Pull the cloth at the same time, and spread the cloth on the flat surface; the flatness measuring mechanism 4 can slide along the direction of the cloth on the printing platform 1, and the flatness measuring mechanism 4 includes a scanner and a positioner, and the scanner is used to scan the cloth , to identify the flatness of the cloth, the locator is used to locate and calculate...

Embodiment 2

[0063] Further, please refer to figure 1 , the spreading mechanism 3 includes a spreading slide 31 and some movable clips 32, and some movable clips 32 are installed on the lower surface of the spreading slide 31, and the movable clips 32 can slide on the lower surface of the spreading slide 31, and several movable clips 32 are used for common When the cloth is clamped, the spreading slide 31 together with a plurality of movable folders 32 can move along the direction of cloth travel.

[0064] Therefore, the cloth can be evenly clamped by the plurality of movable clamps 32 , and the cloth can be spread relatively smoothly on the upper surface of the printing platform 1 through the sliding of the spreading slide 31 , reducing the workload of subsequent leveling.

Embodiment 3

[0066] Further, please refer to Figure 3-4 , The raw material support 21 also includes a plurality of positioning shafts 212, the distance between the positioning shafts 212 and the central installation roller shaft 211 can be adjusted, and the plurality of positioning shafts 212 are used to prevent the cloth from getting loose from the raw material support 21 together.

[0067] Thereby make through the adjustment of the distance of the positioning shaft 212, the cloth roll is relatively fixed on the raw material support 21, prevent the spontaneous expansion of the cloth roll, and affect the judgment of the quantitative feeder 2 on the output of the cloth.

Abstract

The invention relates to the technical field of textile printing, and discloses an automatic cloth spreading device for screen printing and a cloth spreading method thereof, including a printing platform and a quantitative feeder, and the printing platform is provided with a spreading mechanism, a flatness measuring mechanism, a longitudinal Flattening mechanism, horizontal flattening mechanism and controller. The invention detects the flatness of the cloth spread in the printing area through the flatness measuring mechanism, and then expands the cloth between them along the conveying direction through the front-end fixed roller and the rear-end flattening roller of the longitudinal flattening mechanism in order to achieve the accuracy of the unevenness area. The purpose of longitudinal flattening; then through a number of flattening rollers of the horizontal flattening mechanism, the flattening bar moves along the direction perpendicular to the direction of travel of the cloth to expand the cloth, so as to achieve the purpose of longitudinally flattening the uneven area of ​​the cloth, and then Each uneven area is leveled in turn to ensure the flatness of the printing area and avoid printing deviation from affecting the printing quality.

Description

technical field [0001] The invention relates to the technical field of textile printing, in particular to an automatic cloth spreading device for screen printing and a cloth spreading method thereof. Background technique [0002] Printing machine is one of the important equipment in the textile industry, among which screen printing is the most widely used. When performing screen printing, although the printing is realized through the cooperation of scraper and screen, but before that, it is more critical to lay the fabric on the printing plate, whether the fabric is laid smoothly and whether the timing of laying is consistent with the printing. Operation and cooperation are very important. Therefore, in the process of screen printing, the laying process of fabric is also very critical. [0003] However, in the prior art, the cloth is usually leveled by manual or mechanical rolling. For manual work, it is difficult to observe small wrinkles manually, and due to manual limita...
