[0002] A printing machine is a machine for printing words and images. Modern printing machines generally consist of mechanisms such as plate loading, inking, impression, and paper feeding. Its working principle is: first, the words and images to be printed are made into printing plates and installed on the printing machine, and then ink is applied to the areas with words and images on the printing plate by manual or the printing machine, and then directly or indirectly transferred to paper or other printing substrates, so as to reproduce the same printed matter as the printing plate. A four-color printing machine specifically refers to a printing machine that uses four kinds of inks, namely black, medium blue, brown, and green, to achieve the lithographic printing method for map reproduction.
[0003] However, the existing four-color printing machines do not have the function of quickly replacing the material barrel. When actually replacing the material barrel, the user needs to install the material barrel above the equipment, which is often time-consuming and laborious, causing inconvenience in use. Moreover, the existing four-color printing machines do not have the function of stirring the material barrel, and there may be phenomena such as pigment solidification or unevenness. Therefore, a material barrel replacement mechanism for a four-color printing machine is urgently needed to solve the above problems. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model: A four-color printing press material bucket replacement mechanism, including a four-color printing press body 1, a replacement structure 2, a stirring structure 3 and a material bucket 4. The replacement structure 2 includes a fixed seat 21. Four support legs 22 are fixedly connected to the bottom of the fixed seat 21. The fixed seat 21 is slidably connected to a limiting plate 26. A material bucket 4 is installed on the top of the fixed seat 21. The stirring structure 3 includes a bracket 31. The bracket 31 is fixedly connected to the top of the fixed seat 21. Two electric push rods 32 are fixedly connected to the top of the bracket 31. The bottom of the two electric push rods 32 is fixedly connected to a sealing cover 33. The front end of the sealing cover 33 is fixedly connected to a discharge pipe 34. The top of the discharge pipe 34 is fixedly connected to a second feed pipe 13. The top end of the second feed pipe 13 is fixedly connected to a water pump 12. The top of the water pump 12 is fixedly connected to a first feed pipe 11. The top end of the first feed pipe 11 is fixedly connected to the four-color printing press body 1.
[0023] Furthermore, the replacement structure 2 includes two handles 23. Threaded rods 24 are fixedly connected to the sides of the handles 23 close to the fixed seat 21. The threaded rods 24 are threadedly connected to the left and right ends of the fixed seat 21 respectively.
[0024] Further, one side of the threaded rod 24 close to the fixed seat 21 is fixedly connected with an insertion rod 25. The left and right ends of the fixed seat 21 are both slidably connected with the insertion rod 25. Rotate the handle 23 to drive the threaded rod 24 to rotate. The threaded rod 24 drives the insertion rod 25 to move outward, so that the insertion rod 25 is no longer inserted into the slider 27, and thus the insertion rod 25 no longer fixes the slider 27.
[0025] Further, both the left and right sides of the limiting plate 26 are fixedly connected with sliders 27, and the sliders 27 are slidably connected with the fixed seat 21.
[0026] Further, the front side of the limiting plate 26 is fixedly connected with a handle 28. The slider 27 is slidably connected with the insertion rod 25. Pull the handle 28 to drive the limiting plate 26 to move forward and pull out the limiting plate 26.
[0027] Further, the top of the sealing cover 33 is fixedly connected with a motor 35, and the drive shaft of the motor 35 is fixedly connected with a stirring rod 36.
[0028] Further, the stirring rod 36 is rotatably connected with the sealing cover 33. Four stirring blades 37 are fixedly connected to the outer wall of the bottom of the stirring rod 36. Turn on the motor 35 to drive the stirring rod 36 of the motor 35 to rotate. The stirring rod 36 drives the stirring blades 37 to rotate, and the stirring blades 37 stir the pigment in the material bucket 4.
[0029] Working principle:
[0030] During use, turn on the water pump 12. The water pump 12 pumps out the pigment in the material bucket 4 through the second feed pipe 13 and the discharge pipe 34, and conveys it to the four-color printing machine body 1 through the first feed pipe 11. Turn on the motor 35 to drive the stirring rod 36 of the motor 35 to rotate. The stirring rod 36 drives the stirring blades 37 to rotate, and the stirring blades 37 stir the pigment in the material bucket 4. The pigment can be stirred by the motor 35, the stirring rod 36 and the stirring blades 37, so that the pigment is more uniform, and the pigment in the material bucket 4 can be prevented from solidifying. When the pigment in the material bucket 4 is used up and needs to be replaced, rotate the handle 23 to drive the threaded rod 24 to rotate. The threaded rod 24 drives the insertion rod 25 to move outward, so that the insertion rod 25 is no longer inserted into the slider 27, and thus the insertion rod 25 no longer fixes the slider 27. Pull the handle 28 to drive the limiting plate 26 to move forward and pull out the limiting plate 26. Turn on the electric push rod 32 to drive the sealing cover 33 to move upward, so that the sealing cover 33 no longer fixes the material bucket 4, and the material bucket 4 can be replaced. The material bucket 4 can be installed and disassembled without tools through the replacement structure 2 and the electric push rod 32, which is convenient for quickly replacing the material bucket 4 and convenient for use.
