Description

Vertical rail automatic conveying device for transfer printing machine

The invention relates to a printing and dyeing machine in a textile machine, in particular to a vertical rail automatic conveying device of a transfer printing machine. According to the process requirements of transfer printing (especially cold transfer printing), during the transfer printing process, the fabric needs to be slack, flat, tension-free, latitudinal and latitudinal into the transfer area when entering the transfer area. In the area, the warp and weft density and the width of the fabric must reach the specified specifications and dimensions, so as to ensure that the fabric is not deformed and the dye distribution is uniform after being printed. Background technique

Transfer printing technology is a new type of printing method. Its main feature is energy saving and environmental protection. The process is to print the dye on the transfer paper according to the designed pattern, and then use physical (pressurization, heating) or chemical. The method of adding an auxiliary agent transfers the dye pattern on the transfer paper to the printed fabric. The early transfer printing was carried out by hot-press transfer printing (ie, thermal transfer printing). Using the physical properties of the dye sublimation, the transfer paper was combined with the fabric to heat the dye, and the heated dye sublimated into the surface or inside of the fabric. Transfer printing. Thermal transfer printing can only be printed on chemical fiber fabrics with disperse dyes. The dye varieties and fabric varieties are greatly limited, especially for reactive dyes with better vividness. In recent years, with the successful development of new dyes and new auxiliaries, reactive dye transfer printing for cellulose fibers such as cotton and hemp has been carried out by means of room temperature pressurization, and after cold transfer or steaming. The color has a strong stereoscopic effect, high dye transfer rate, less water for washing, and reduces pollutant emissions, achieving the purpose of environmentally friendly printing. There are usually two types of fabric transport methods for these two printing methods: one is known as guide roller transport or direct conveyance of rolling mill, such as the fabric transport in the Chinese patent ZL200720072965.7 "Roller transfer device of cold transfer printing machine" In this way, the method of conveying directly from the rolling roller is used. The fabric tension and width in the cloth method are difficult to control, especially the knitted fabrics which are very sensitive to tension are prone to curling and weft shrinkage and warp stretching; the other is the horizontal rail chain conveying device. For example, the Chinese patent ZL200820055536.3 "automatic conveying device for transfer printing machine" uses the horizontal rail conveying device. The advantage of this conveying method is that the width of the fabric is not free when it is in the conveying process. The shortcoming of the stable defect is that the horizontal rail arrangement has a large area. Due to the structural limitation, the fabric cannot enter the transfer area in the shortest time and the shortest route after the needle is removed, thereby causing the fabric to be twice after the needle is removed. Elongation and secondary crimping. The direct effect of the above two modes of transfer on the quality of transfer printing is that the fabric is skewed after printing, the weft arc, the left and right color unevenness of the fabric, the flower shape deformation, the width dimension and the gram weight instability. Summary of the invention

The cloth feeder before the feeding is used for storing the fabric output from the rolling unit, and the feeding speed of the left and right sides of the fabric is controlled during the overfeeding of the upper needle to correct the unevenness of the weft yarn in the fabric feeding process. Due to the particularity of the cold transfer printing, the perpendicularity (ie, the weft) of the weft yarn and the warp yarn should be kept within a certain range when the fabric enters the transfer area, otherwise the flower pattern of the transferred fabric will be severe after washing and wefting. Deformation, defective products. The device can control the occurrence of fabric skew from the beginning of the cloth, thereby improving the printing quality.

The fabric supporting device is configured to support the middle of the fabric during the conveying process with a topping belt and a rope-like cloth belt, thereby reducing the sagging of the fabric due to its own weight. After the fabric is rolled by the rolling device, the surface contains about 55-65% of the treatment liquid, and the middle portion of the fabric will sag seriously during the flat feeding of the vertical guide rail, and the treatment liquid in the fabric will also sag with the sag of the fabric. The uneven distribution on the surface of the fabric, the transfer rate of the dye will be greatly different when the transfer printing is carried out, resulting in a more serious chromatic aberration.

The above-mentioned active needle removing device peels off the fabric fixed to the needle plate by the actively rotating needle removing roller and the needle removing roller, which is different from the passive needle removing wheel device in the printing and dyeing machine. Due to the wet fabric stretched by the rolling liquid, especially the high-elastic or light-knit fabric, the needle pull-out force is greatly deviated after the end of the tentering, and the pull-out tension has a greater influence on the fabric tension, and the smaller The de-needle tension is sufficient to cause a large ridge of the fabric, thereby causing deformation of the fabric print pattern after washing.

The active needle removing device further comprises a pair of interacting active decoupling rollers, the lower active decoupling roller is a steel roller which is coated with a matte material, and the active decoupling roller is a metal roller, and the fabric is removed during the decoupling process. Pressing on the roller reduces the area of influence of the decoupling tension and reduces the generation of the weft arc.

The active feed device actively transports the unbroken fabric to the transfer area. Because the fabric is unevenly distributed in the left, middle, and right directions during the stretching process, the shrinkage does not match after the needle is removed. This inconsistency will cause weaving.

The production of the weft arc. The active feed device can effectively alleviate this problem. The active feed device consists of an active feed roller and its driving motor and reducer, wherein the active feed roller is a steel roller that is coated with matte material.
