Description

Coating and picture integrated printing equipment

Technical Field

The utility model belongs to the technical field of digital printing, and particularly relates to coating and picture integrated printing equipment.

Background

The coating on the digital printing cloth is very important, and mainly comprises the following aspects of enhancing ink adsorption and permeation, enabling the ink to be uniformly attached, controlling permeation depth, ensuring printing to be clear and complete and not to be feathered, improving color expression, reducing color, improving saturation and expanding color gamut, enabling printing effect to be more vivid, protecting the printing cloth, having the functions of water resistance, moisture resistance, ultraviolet resistance and wear resistance, prolonging service life, improving physical properties, enhancing flexibility, enabling the printing cloth to be convenient to fold and install, improving flatness, providing good foundation for printing, and guaranteeing printing quality.

But not all print cloths are coated. Commercial printing cloth commonly used for digital printing, such as spray painting cloth, photo cloth and the like, has a coating, however, some simple printing cloth which is used for temporary display and has low requirement on printing effect, or natural fiber cloth such as pure cotton cloth and the like can have no coating when being used for printing, and a user is required to decide whether to coat the cloth or not according to the requirement.

However, in practical application, there is a contradiction between batch and cost in coating the cloth. If the cloth produced by the cloth factory is not coated, and a part of users only need a small batch of coated cloth, the supply and demand are mismatched, which brings a lot of trouble to the users. They may face a cumbersome process of additionally searching for coating processing services, which not only consumes time and effort, but also greatly increases the cost due to small batch processing, making the simple requirement troublesome.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1, the utility model is a coating and picture integrated printing device, which comprises a cloth scroll 11, a first cleaning adhesive roller set 12, a second cleaning adhesive roller set 14, a hot knife 9, a first cloth pressing roller 15, a cloth feeding roller 16, a printing trolley 17, a color box 5, a cloth outlet roller 2, a second cloth pressing roller 1 and a plurality of passing rollers which are sequentially arranged.

The uncoated cloth roll 10 is mounted on a cloth roll 11, the cloth roll 11 is driven by an ac servo motor, and the motor drives the cloth roll 11 to rotate through a gear reducer. The ac servomotor is operated in a torque mode, and the winding diameter of the cloth roll is detected by means of a sensor 13 arranged beside the cloth roll shaft 11, so that precise tension control during cloth unwinding is realized.

The uncoated spray painting cloth 23 passes through the first cleaning adhesive roller set 12 and the second cleaning adhesive roller set 14, and the two sets of adhesive rollers can remove broken short fibers on the spray painting cloth 23, so that the color development effect of the subsequent printing picture is prevented from being influenced by the fibers. Then, at the first passing roller 8, the hot knives 9 distributed at the left and right ends are used for cutting out the wrinkled and uneven parts of the cloth edge, and the hot knives 9 at the two ends are controlled to lift by the hot knife shaft 7, as shown in fig. 2.

The inkjet cloth 23 treated as described above reaches the cloth roller 16 through the second and third passing rollers 6 and 24. The cloth feeding roller 16 is driven by an alternating current servo motor through a speed reducer, and meanwhile, the first cloth pressing roller 15 applies proper pressure to the spray painting cloth 23 on the cloth feeding roller 16, so that accuracy of the spray painting cloth in the stepping direction in the printing process is ensured.

The coating of the spray painting cloth passing through the cloth roller 16 and the picture printing work are both born by the print trolley 17. As shown in fig. 3, the print carriage 17 is provided with a frame print nozzle group 17A for frame printing and a coating print nozzle group 17B for inkjet printing, which are arranged up and down respectively, and the lower coating print nozzle group 17B can print the inkjet before the frame print nozzle group 17A, and the up and down collaborative operation is performed to complete the inkjet from coating to frame integrated printing process.

Since the print carriage 17 is obliquely disposed, the coating printing stage 18 is also obliquely disposed below the coating printing nozzle group 17B, and the screen printing stage 20 is also obliquely disposed below the screen printing nozzle group 17A.

Coating printing works by depending on a coating printing platform 18, and a coating electric heating plate 19 is arranged below the coating printing platform 18. During the coating printing process, the coating electric heating plate 19 will heat and dry the printed coating. The step can quickly evaporate the water or the solvent in the coating, so that the coating is quickly solidified, thereby avoiding the problems of halation, fading and the like during the printing of the subsequent picture and ensuring the printing quality of the subsequent picture.

The screen printing platform 20 used for screen printing is provided with an ink-sucking device. In the picture printing process, the spray head sprays ink at high speed, so that the phenomenon of flying ink can be generated, and the flying ink drop can be timely pumped away by the ink pumping device, so that the flying ink is prevented from falling on a picture being printed, and the picture printing is ensured to be kept clear.

As shown in fig. 4, the print carriage of the present utility model may also take another form. The screen printing jet group 17A and the coat printing jet group 17B are respectively arranged on two print carriages. The present utility model is not limited to any configuration of the print carriage, as long as the process of printing the coating and then printing the picture is followed on the uncoated cloth.

The printed inkjet cloth 23 sequentially passes through the fourth roller 21 and the fifth roller 22 to enter the color development tank 5. In the color development box 5, the spray painting cloth develops color under a high-temperature environment, so that the color of the picture is fully developed and stabilized. And then, the spray painting cloth after the color development treatment passes through the sixth passing roller 4 and the seventh passing roller 3, finally reaches the cloth outlet roller 2 and the second cloth pressing roller 1, and the whole printing process is finished so far, and the finished cloth is output.

Based on the above description, the printing flow of the apparatus is shown in fig. 5. Regardless of the layout mode adopted by the device, the printing mode is completely consistent with the flow shown in fig. 5, and the whole steps from cloth roll cleaning, hot knife cutting, coating printing and drying, picture printing, color development and cloth discharge are covered.
