[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention aims to solve the problems that only the height of the printing roller can be adjusted, the ink on the printing roller cannot be adjusted and controlled, resulting in the ink on the printing roller not being evenly spread during printing, causing unclear printing, and at the same time, there is no way to handle the excess ink on the printing roller, thus generating waste ink, causing waste of ink, increasing production costs, and polluting the environment. It provides an adjustable bracket for printing and packaging as shown in Figures 1-3 Figure 16, which includes a bottom plate 1. Two servo electric cylinders 11 are fixedly connected to the top surface of the bottom plate 1. An electric push rod 12 is arranged on the top of the servo electric cylinder 11. The top end of the electric push rod 12 is fixedly connected to a gantry frame 13. A printing roller 21 and a cotton roller 23 are arranged on the inner wall of the gantry frame 13. The outer surface of the cotton roller 23 is in movable contact with the printing roller 21, and the cotton roller 23 can be elastically deformed. By setting the servo electric cylinder 11 and the electric push rod 12, the height of the gantry frame 13 can be adjusted according to the size of the package. During adjustment, the servo electric cylinder 11 drives the electric push rod 12 to move up and down, and the electric push rod 12 drives the gantry frame 13 at the top to move. The movement of the gantry frame 13 makes the internal printing roller 21 and cotton roller 23 move. When the printing roller 21 contacts the package, the adjustment is completed. It has good applicability and is convenient for printing packages of different sizes. A printing plate for printing is installed on the outer circumference of the printing roller 21, and the printing plate is used to transfer ink to the analog image carrier on the package. This is a mature technology in the prior art and is not shown in the drawings. The setting of the cotton roller 23 can absorb the excess ink, thereby controlling the ink flow. During printing, the printing roller 21 prints on the package. During the printing process, the cotton roller 23 evenly spreads the ink on the printing roller 21, so that the ink is evenly distributed on the printing plate, which helps to achieve a clear and consistent printing effect.

[0025] Furthermore, a material collecting box 24 is fixedly installed on the inner wall of the gantry 13 near one side of the cotton roller 23. A part of the cotton roller 23 is located inside the material collecting box 24. The lower side of the side plate of the material collecting box 24 is close to the printing roller 21. A pressing plate 25 is fixedly connected to the inner wall of the lower side of the side plate of the material collecting box 24. The top end of the pressing plate 25 is in movable contact with the outer surface of the cotton roller 23. During the rotation of the cotton roller 23, the excess ink is collected into the material collecting box 24, and the pressing plate 25 squeezes the cotton roller 23 to make the ink inside it flow out. Due to the elastic deformation structure of the cotton roller 23, after the ink inside it is squeezed out, the cotton roller 23 returns to its original state. The ink juice collected in the material collecting box 24 can be reused, reducing the generation of waste ink juice, avoiding the waste of ink juice, reducing the production cost, and reducing the environmental pollution.

[0026] In the present utility model, a motor 4 is fixedly connected to one side of the outer wall of the gantry 13. There are two transmission wheels 41 arranged on one side of the outer wall of the gantry 13. The transmission wheels 41 are respectively sleeved on the ends of the first rotating rod 2 and the second rotating rod 22. The transmission wheels 41 are connected by a transmission belt 42. The rotating shaft of the motor 4 is fixedly connected to the end of the first rotating rod 2. During use, a device for moving the package (such as a conveyor or other devices, which are not limited here) is usually arranged on the bottom plate 1, which is a mature technology in the prior art and is not shown in the figure. When the motor 4 is turned on, the motor 4 rotates to drive the first rotating rod 2 to rotate. The first rotating rod 2 rotates to drive one transmission wheel 41 to rotate. One transmission wheel 41 drives the other transmission wheel 41 to rotate through the transmission of the transmission belt 42, achieving the effect of synchronous rotation of the second rotating rod 22.

[0027] Furthermore, a first rotating rod 2 and a second rotating rod 22 are rotatably arranged inside the gantry 13. A printing roller 21 is fixedly connected to the outer surface of the first rotating rod 2. A cotton roller 23 is fixedly connected to the outer surface of the second rotating rod 22. During the rotation of the first rotating rod 2 and the second rotating rod 22, the printing roller 21 and the cotton roller 23 on them also rotate, and the cotton roller 23 adsorbs the ink on the printing roller 21.

[0028] It should be noted that the cross-sectional diameter of the cotton roller 23 is smaller than that of the printing roller 21, and the cotton roller 23 is located above the printing roller 21. The bottom surface of the material collecting box 24 is higher than the bottom of the printing roller 21. Both the cotton roller 23 and the material collecting box 24 are located above the bottom of the printing roller 21. When the printing roller 21 prints the package, the cotton roller 23 and the material collecting box 24 will not affect the printing roller 21, ensuring the normal operation of the printing work.

[0029] In the present utility model, a plurality of through holes 27 are formed through the bottom of the extrusion plate 25, and a filter plate 26 is fixedly connected to the bottom of the inner wall of the material receiving box 24; after the ink is extruded through the through holes 27, the ink flows down along both sides of the through holes 27, and the ink on the side wall of the through holes 27 and the material receiving box 24 flows downward through the extrusion plate 25, and after being filtered by the filter plate 26, it is reused, thereby realizing the reuse of resources.

[0030] It should be noted that a circulation pump 3 is fixedly connected to the bottom of the outer wall of the material receiving box 24. The circulation pump 3 is communicated with a feeding pipe 31. A sprinkling frame 32 is fixedly connected to the top of the inner wall of the gantry frame 13. The top surface of the sprinkling frame 32 is communicated with the end of the feeding pipe 31. The sprinkling frame 32 is located directly above the printing roller 21; the circulation pump 3 conveys the filtered ink inside the material receiving box 24 to the feeding pipe 31, and through the feeding pipe 31 to the inside of the sprinkling frame 32. There are inkjet nozzles on the sprinkling frame 32, and the sprinkling frame 32 sprays the filtered ink onto the printing roller 21 for reuse.
