[0002] In the sofa fabric manufacturing industry, printing is a key process for giving fabrics beautiful patterns and rich colors. Currently, most common sofa fabric printing equipment uses printing rollers for printing operations.

[0003] In existing technologies, during the printing process, the printing rollers are exposed to the external environment for a long time, making them highly susceptible to corrosion from environmental factors such as dust and moisture. This leads to wear and corrosion on the surface of the printing rollers, which not only affects the service life of the printing rollers but also causes quality problems such as blurry patterns and color differences in the printed patterns. Furthermore, during the printing process, the organic solvents in the pigments volatilize and produce harmful gases. If these gases are not treated in time, they will accumulate in the working environment, posing a threat to the health of the operators and potentially causing safety hazards. Utility Model Content

[0023] like Figures 1 to 5 As shown, a sofa fabric printing device includes: a workbench 1, a plurality of printing rollers 2 installed on the top surface of the workbench 1, a plurality of support plates 21 fixedly connected to the bottom surface of the workbench 1, the support plates 21 having a rectangular cross-section, trapezoidal plates 3 fixedly connected to the top surface of the workbench 1 at the front and rear sides of the printing rollers 2, two movable frames 4 movably connected between two adjacent trapezoidal plates 3, and the same top plate 5 fixedly connected between the two movable frames 4 with the same front and rear cross-section.

[0024] In this embodiment, during the operation of the printing equipment, the printing roller 2 is protected by the trapezoidal plate 3, the movable frame 4, and the combined top plate 5, thereby reducing the impact of the external environment on the printing roller 2 and improving its protective performance.

[0025] In this embodiment, the movable frame 4 is inclined on the side near the trapezoidal plate 3 and a slider 18 is fixedly connected near the bottom. Slide grooves 19 are provided on both the left and right side walls of the trapezoidal plate 3. The slider 18 is movably connected to the slide grooves 19, which allows the movable frame 4 and the trapezoidal plate 3 to move stably.

[0026] In this embodiment, a filter screen 20 is fixedly connected inside the movable frame 4. The filter screen 20 is trapezoidal and can filter the gas entering the printing roller 2, reduce the impact on the printing roller 2, and improve protection.

[0027] In this embodiment, an adjustment component 6 is provided on two adjacent movable frames 4. The adjustment component 6 includes a side plate 10. The side plate 10 is fixedly connected to each movable frame 4. The same horizontal plate 11 is movably connected to two adjacent side plates 10. A vertical plate 12 is fixedly connected to the center of the bottom surface of the horizontal plate 11. Two positioning rods 13 are movably connected to the vertical plate 12. A circular plate 14 is fixedly connected to the end of the positioning rod 13 away from the worktable 1. A spring 15 is sleeved on the positioning rod 13. The two ends of the spring 15 are fixedly connected to the circular plate 14 and the vertical plate 12, respectively. Several positioning holes are opened on the front and rear side walls of the worktable 1. One of the positioning rods 13 is inserted into the positioning hole.

[0028] In this embodiment, by pulling the handle 16, the handle 16 drives the circular plate 14 to move. The circular plate 14 drives the positioning rod 13 to be pulled out from the positioning hole and stretches the spring 15. Then, an upward force is applied to the handle 15, causing the vertical plate 12 and the horizontal plate 11 to move upward. At this time, the slider 18 on the movable frame 4 moves in the groove 19 on the trapezoidal plate 3, causing the movable frame 4 to move along the side wall of the trapezoidal plate 3. The movable frame 4 drives the top plate 5 to separate. When the top plate 5 moves to the specified height, the lower positioning rod 13 is inserted into the positioning hole on the side wall of the worktable 1 to achieve the positioning of the top plate 5. At this time, the operator can install the specified printing roller 2 on the worktable 1 according to the actual printing needs. After the printing roller 2 is installed, the handle 16 is pulled to pull the positioning rod 13 out from the positioning hole and cause the top plate 5 to move down to merge together. Then, the upper positioning rod 13 is inserted into the positioning hole to lock the vertical plate 12. This can achieve convenient installation of the printing roller 2 and stable protection.

[0029] In this embodiment, a handle 16 is fixedly connected to the side wall of the circular plate 14 away from the positioning rod 13, which facilitates the adjustment of the movable frame 4.

[0030] In this embodiment, limiting plates 17 are fixedly connected to both the left and right sides of the horizontal plate 11. The limiting plates 17 are rectangular and their length and width are both greater than the cross-sectional length and width of the horizontal plate 11, which can limit the movement of the movable frame 4 and improve the stability of the equipment.

[0031] In this embodiment, several vertical pipes 7 are evenly distributed and fixedly connected on each top plate 5. The top ends of the several vertical pipes 7 are fixedly connected to the same horizontal pipe 8. One end of the horizontal pipe 8 is fixedly connected to an air extractor 9, and the air extractor 9 is fixedly connected to the top plate 5.

[0032] In this embodiment, when the printing roller 2 is printing sofa fabric, the exhaust port of the vacuum pump 9 is connected to an external air purification device, and the vacuum pump 9 is started by an external power source. This allows the harmful gases generated by the volatilization of organic solvent pigments during the printing process to be extracted through the vertical pipe 7 and the horizontal pipe 8. The harmful gases are then transported to the air purification device for purification treatment by the vacuum pump 9, thereby reducing the impact on the production environment and operators.

[0033] Implementation Plan: In use, the operator first pulls the handle 16, causing the handle 16 to move the circular plate 14. The circular plate 14 then pulls the positioning rod 13 out of the positioning hole, stretching the spring 15. An upward force is then applied to the handle 15, causing both the vertical plate 12 and the horizontal plate 11 to move upwards. At this time, the slider 18 on the movable frame 4 moves within the groove 19 on the trapezoidal plate 3, causing the movable frame 4 to move along the side wall of the trapezoidal plate 3. The movable frame 4 causes the top plate 5 to separate. When the top plate 5 reaches the designated height, the lower positioning rod 13 is inserted into the positioning hole on the side wall of the worktable 1 to position the top plate 5. At this point, the operator can install the designated printing roller 2 on the worktable 1 according to the actual printing needs. After the printing roller 2 is installed, the handle 16 is pulled... Handle 16 causes the positioning rod 13 to be pulled out of the positioning hole, and the top plate 5 to move down and merge together. Then, the upper positioning rod 13 is inserted into the positioning hole to lock the vertical plate 12. At this time, the printing roller 2 is protected by the trapezoidal plate 3, the movable frame 4 and the top plate 5, reducing the impact of the external environment on the printing roller 2 and improving its protection. When the printing roller 2 is printing sofa fabric, the exhaust port of the air extractor 9 is connected to the external air purification equipment and the air extractor 9 is started by the external power supply. The harmful gases generated by the volatilization of organic solvent pigments during the printing process are extracted through the vertical pipe 7 and the horizontal pipe 8 and transported to the air purification equipment for purification treatment by the air extractor 9, reducing the impact on the production environment and operators.
