[0025] The following is a detailed description of the specific settings and functions of this embodiment. An unwinding device and a rewinding device are respectively arranged on both sides of the printing device. During the process of the threaded knitted fabric being arranged from the unwinding device to the rewinding device, the surface of the fabric passes through the printing device. The threaded knitted fabric extends from the guide roller 2 at one end to the top surface of the base 1, and passes through the lower surface of the printing roller 4 and the storage plate 5 one by one until the threaded knitted fabric is guided to the guide roller 2 at the other end, and finally recovered to the rewinding device. The surface of the printing roller 4 is provided with the pattern required for printing. The threaded knitted fabric passes through each printing When the printing roller 4 is used, the corresponding pattern will be printed on the printing roller 4. At the same time, a storage plate 5 is arranged behind the printing roller 4. A flexible and fluffy sponge sheet is arranged inside the storage plate 5 to absorb a sufficient amount of liquid. The storage plate 5 is suspended above the threaded knitted fabric. After the printing roller 4 prints and dyes the threaded knitted fabric, the upper surface of the storage plate 5 is squeezed periodically to add a certain amount of water to the threaded knitted fabric, so that the fuel on the printing roller 4 can fully penetrate the fabric, thereby making the printed pattern deeper and avoiding problems such as uneven coloring due to drying of the fabric.

[0026] Embodiment 2

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, rubber pads 8 are fixedly connected at the four corners of the bottom surface of the base 1. Cams 14 are fixedly connected to both ends of the printing roller 4 and penetrate the side walls of the fixed frame 3. The outer wall of the cam 14 is coated with lubricant. Ear plates 7 are fixedly connected to both ends of the lifting frame 6, and the bottom end of the ear plate 7 is fixedly connected to the first sliding column 9. The outer wall of the first sliding column 9 is slidably connected to the first sliding seat 10, and the first sliding seat 10 is fixedly connected to the outer wall of the base 1. A limiting circular plate 12 is fixedly connected to the bottom end of the first sliding column 9, and a spring 11 is fixedly connected between the limiting circular plate 12 and the first sliding seat 10.

[0028] The effect achieved by the entire embodiment is that the printing roller 4 is arranged on the threaded knitted fabric, and the printing roller 4 itself is rotated by the movement of the fabric, so that the pattern on the printing roller 4 is completely printed on the upper surface of the threaded knitted fabric. The printing roller 4 can also be driven to rotate by an external driving motor. It is only necessary to synchronize the rotation speed of the printing roller 4 with the movement speed of the threaded knitted fabric to ensure the integrity of the fabric coloring. An extrusion seat 16 is correspondingly arranged above each storage plate 5, and the extrusion seat 16 is connected to a lifting frame 6, wherein the edges of both sides of the lifting frame 6 are connected to the lower When the printing roller 4 rotates, the cam 14 on the outside will also be driven to rotate, and the cam 14 will drive the upper lifting frame 6 to move up and down periodically. When the lifting frame 6 moves to the lower limit position, the squeezing seat 16 is squeezed and contacted with the sponge on the storage plate 5, so as to squeeze out the liquid in the storage plate 5, so as to ensure that the fabric that needs to be printed is soaked again after the fabric rotates one circle, thereby improving the quality of the printed pattern of the fabric. When the lifting frame 6 moves to the upper limit position, the squeezing seat 16 is separated from the storage plate 5 to control the flow rate of the liquid squeezed by the storage plate 5.

[0029] The use method and working principle of the device: First, unwinding equipment and winding equipment are respectively arranged on both sides of the printing device, and the threaded knitted fabric extends from the guide roller 2 at one end to the top surface of the base 1, and passes through the lower surface of the printing roller 4 and the storage plate 5 one by one;

[0030] Then, the threaded knitted fabric drives the upper printing roller 4 to rotate during the movement on the base 1, so that the printing roller 4 prints the surface pattern on the upper layer of the fabric, and at the same time, the printing roller 4 drives the outer cam 14 to rotate, and the cam 14 drives the upper lifting frame 6 to move up and down periodically. When the lifting frame 6 moves to the lower limit position, the extrusion seat 16 is squeezed and contacted with the sponge on the storage plate 5, so as to squeeze out the liquid in the storage plate 5;

[0031] Finally, the threaded knitted fabric is guided to the guide roller 2 at the other end. Before being recycled to the winding device, a dryer is set to dry the threaded knitted fabric. Finally, it is recycled to the winding device to complete the printing process of the threaded knitted fabric.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
