Description

Technical Field

[0001] The present invention relates to the technical field of cloth printing, and in particular to a high-efficiency, green and environmentally friendly printing process. Background Art

[0002] Green and environmentally friendly printing is a printing method that uses environmentally friendly materials to print on the surface of products. The printing process produces less pollution, and the printed products are easy to recycle and reuse after being discarded. It is a printing method that can be naturally degraded and has little impact on the ecological environment. In the process of double-sided printing on fabrics, two sets of printing rollers and printing plates are generally required for printing. Each printing roller is arranged on a different side of the fabric to roll and dip the ink to print the pattern.

[0003] For example, the authorization announcement number "CN211251726U" is named a double-sided printing mechanism for composite fiber textile fabrics. This printing mechanism is a commonly used printing method. By arranging printing plates and printing rollers at different positions on the fabric, the ink pattern on the printing roller is transferred to the surface of the fabric as the fabric passes through the two printing plates and the printing roller in sequence.

[0004] However, in actual use, this type of printing mechanism lacks a structure for tensioning the fabric, so an additional tensioning mechanism is required to tension the fabric. This is to keep the conveyed fabric in a taut state to prevent blank printing areas from appearing in the wrinkled areas of the loose fabric during printing. In addition, the two printing rollers are far apart, and each printing roller requires a separate ink tank for oil supply. Each ink tank also needs to be refilled with ink through a pipeline later, which increases the overall cost of the printing machine.

[0005] In view of this, it is necessary to design a fabric printing device that can concentrate printing rollers at different positions on an ink tank for oil supply, and can combine the two process flows of double-sided printing of fabrics and tensioning of fabrics, so as to achieve high-efficiency double-sided printing of fabrics.

[0024] Beneficial effects of the present invention:

[0025] 1. An arc-shaped support block is arranged on the outside of the cloth, and a support plate is slidably connected to the inside of the arc-shaped support block. The top surface of the support plate is slidably connected to a movable block, and the inner side of the movable block is rotatably connected to a torsion roller. The movable block is fixed by winding and fixing it with a traction rope and a winding wheel. The two movable blocks are arranged in the middle of the arc-shaped support block under the traction of the traction rope, so that the two torsion rollers on the two movable blocks clamp the cloth in a twisted state. When the cloth is transmitted between a printing roller and a printing plate, the printing roller rotates to transfer the ink pattern to one side of the cloth. After the cloth passes through the two torsion rollers, the cloth is twisted so that the printed side of the cloth is transferred to a position away from the other printing roller. When the cloth passes through the printing roller, the printing roller can print on the unprinted area on the cloth, thereby realizing printing patterns on both sides of the cloth at the same time. The electromagnet inside the block is powered off, so that the two movable blocks are no longer in a fixed state. At this time, the two movable blocks are fixed together by the traction spring, and the two motors rotate at the same time to drive the winding wheel to rotate the winding rope, so that the two movable blocks move straightly in the directions away from each other, so that the distance between the two torsion rollers becomes larger, which makes it easier for the torsion rollers to adapt to the materials of different fabrics and flexibly adjust the degree of torsion tension of the fabric. When the two movable blocks are in contact with each other, the fabric between the two torsion rollers is in a maximum torsion tension state. When the two movable blocks gradually move in the directions away from each other, the degree of torsion tension of the fabric gradually decreases, so that the torsion tension of the fabric can be flexibly adjusted, and the fabric can also be tensioned in the process of twisting the fabric, so as to combine the double-sided printing of the fabric after twisting with the tension of the fabric, which is conducive to improving the efficiency of double-sided printing of the fabric.

[0026] 2. Make the two movable blocks fit together so that the twisting rollers on the two movable blocks can fully twist the fabric (refer to the instructions Figure 6 ), at this time, the motor at the left end of the arc support block rotates to rewind the traction rope, and the motor at the right end of the arc support block rotates to release the traction rope, so that the support plate can carry the two movable blocks and the two twisting rollers to rotate toward the left end of the arc support block in an arc trajectory, wherein the center of the arc support block is arranged at the center position of the cloth, and at this time the cloth on the top of the twisting roller is twisted again, so as to tension the cloth transmitted above the twisting roller, thereby achieving the effect of adjusting the tension of the cloth above the twisting roller; conversely, the motor at the right end of the arc support block rotates to rewind the traction rope, and the motor at the left end of the arc support block rotates to release the traction rope, so that the support plate can carry the two movable blocks and the two twisting rollers to rotate toward the right end of the arc support block in an arc trajectory, and at this time the cloth at the bottom of the twisting roller is twisted again, so as to tension the cloth transmitted below the twisting roller, thereby achieving the effect of adjusting the tension of the cloth below the twisting roller;

[0027] 3. By rotating and connecting the two printing rollers to the open end of the ink tank, one ink tank can provide ink to the two printing rollers at the same time. The two rollers inside the ink tank rotate and drive the sponge belt on the transmission belt. The sponge belt can transfer the ink inside the ink tank to the outside of the printing roller. In addition, the right shaft rod three is rotatably connected inside the transmission belt, and the right multiple paddles two are fixed on the outside of the shaft rod three. The right shaft rod two is rotatably connected between the two transmission belts, and the right multiple paddles one is fixed on the outside of the shaft rod two. In the process of conveying ink with the transmission belt, the transmission belt can rotate with the paddles one and two to stir the ink, so that the different components of the ink can be fully mixed, thereby improving the quality of ink printing, and combining the transfer of ink with the stirring of ink, which is beneficial to improving the ink processing efficiency during the printing process.
