Description

Technical Field

[0001] The invention belongs to the field of fabric printing, and in particular relates to a fabric printing flower height control system. Background Art

[0002] Fabric printing is one of the important means of textile processing. Through the process of forming patterns on fabrics by printing methods, a variety of printing methods can be achieved, such as direct paint printing, silk printing, knitted underwear printing, etc. These printing methods not only enrich the visual effects of fabrics, but also provide consumers with a variety of choices; The printed pattern is repeated on the surface of the fabric to ensure the continuity of the fabric quality. The control of the pattern height (circumference) is an important data that reflects the shape preservation and reproduction of the pattern. Due to the physical limitations of the traditional flat screen or rotary screen printing, the height circumference of each pattern is usually 640mm, 920mm and 1080mm. The control method generally adopted is to manually measure and compare the pattern height data printed on the edge of the cloth during the subsequent finishing process, and then feed it back to the operator of the finalizing machine. The operator of the machine adjusts the overfeed data to achieve the control of the pattern height; However, the existing technology has the following shortcomings: the traditional control method has the disadvantages of time lag, low control accuracy, high labor intensity, etc., especially with the popularization of digital printing technology in recent years, more and more digital printing unique patterns such as gradient flowers, rendering flowers, non-geometric patterns, long length flowers, etc., are difficult to measure and control by hand, which increases the time and difficulty of measurement and reduces work efficiency; and in some extreme examples, the circumference of the high-end needs to reach more than 1500mm or even close to 2000mm due to different styles, which cannot be measured manually at any time.

An eccentric column 542 is fixed on the rotating disk 541, and a swing block 543 is slidably matched on the eccentric column 542. As the rotating disk 541 drives the eccentric column 542 to rotate, the swing block 543 is driven to swing left and right with the help of the limited sliding between the swing block 543 and the eccentric column 542. A positioning column is provided on the swing block 543 for positioning, and the positioning column is rotated with the positioning column.

With the help of the protruding tube 64, the fabric can be shaken during feeding and conveying, thereby shaking off dust on the surface of the fabric, thereby preventing dust from affecting the finished printing effect.

[0035] Based on the above embodiment, the specific working principle is as follows: The textile fabric is automatically conveyed and fed through the conveying mechanism. At the same time, the main shaft 62 and the fixed plate 63 on the shaking mechanism 6 are driven to rotate through the control box 2. The raised tubes 64 located at both ends of the fixed plate 63 can alternately contact with the bottom of the fabric during rotation, thereby producing a slight impact on the fabric, thereby causing the surface of the fabric to shake, and the dust adhered to the surface of the fabric can be shaken off, so as to avoid the adhesion of dust and affect the printing effect of the fabric during printing. The installation position of the raised tube 64 on the clamping groove 631 can be adjusted by pushing the raised tube 64, thereby adjusting the distance between the raised tube 64 and the fabric and the vibration amplitude; Then, as the textile fabric is transported, it will contact the flattening mechanism 4 on the machine body 1, and the arc-shaped structure at the bottom of the pressing plate 42 will contact the textile fabric. With the help of the conveying movement of the fabric, the fabric can be flattened and adjusted to prevent wrinkles on the fabric, thereby improving the yield and effect of printing.

As the turntable 541 rotates, the eccentric column 542 is driven to rotate together, and the limiting sliding between the swing block 543 and the eccentric column 542 drives the swing block 543 to swing left and right when the turntable 541 rotates, and drives the gear ring 545 to rotate half a circle through gear meshing. As the gear ring 545 rotates, the bottom box 51 connected thereto is driven to swing together, and the multiple fans 512 in the bottom box 51 are driven by the control box 2 to generate upward wind force, and the wind force will become hot air after passing through the heating tube 511, so as to dry the printed fabric, so as to avoid the printing being incomplete due to the printing being not completely dried just after the processing, thereby affecting the quality.
