Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] Example 1: As Figures 1-3 As shown, a color-fixing structure for a roll printing machine includes a base 1. A gantry frame 2 is fixedly connected to the top of the base 1. Limiting grooves 6 and 7 are respectively opened on the left and right sides of the outer wall of the gantry frame 2. A fixing plate 3 is fixedly connected to the left side of the outer wall of the gantry frame 2. An electric push rod 4 is fixedly connected to the front end of the top of the fixing plate 3. A fixing block 5 is fixedly connected to the rear end of the electric push rod 4. A support rod 8 is fixedly connected to the right side of the fixing block 5. The left end of the support rod 8 passes through the limiting groove 6 and is slidably connected to its inner wall. The right end of the support rod 8 passes through the limiting groove 7 and is slidably connected to its inner wall. A fixing clamp 9 is fixedly connected to the left end of the support rod 8. A shaft 10 is rotatably connected to the bottom end of the fixing clamp 9. The left side of the shaft 10 is connected to the base through a transmission assembly 11. The base 1 is connected to the shaft 10. A locking block 12 is fixedly connected to the right side of the shaft 10. The locking block 12 is connected to the roller brush 14 through the locking groove 13. A sliding rod 18 is fixedly connected to the top right side of the fixed clamping plate 9. A thread 20 is opened on the right side of the sliding rod 18. An adjusting block 21 is threaded to the right side of the thread 20. A spring 22 is installed on the outside of the sliding rod 18. A movable clamping plate 15 is fixedly connected to the right side of the spring 22. A through hole 19 is opened on the top left side of the movable clamping plate 15. The through hole 19 is slidably connected to the outside of the sliding rod 18. A through groove 16 is opened on the middle left side of the movable clamping plate 15. The through groove 16 is slidably connected to the support rod 8. The movable clamping plate 15 is connected to the roller brush 14 through a locking block 2 17. A spray seat 23 is installed on the middle front side of the support rod 8.

[0032] Specifically, the electric push rod 4 is fixed to the gantry 2 through the fixing plate 3, and the fixed block 5 is pushed to move the supporting rod 8, so as to flexibly adjust the position of the roller brush 14, facilitate the fixing operation of the printed matter at different positions, and greatly improve the flexibility and applicability of the fixing. In the transmission assembly 11, the gear 1101 is fixed on the left side of the shaft rod 10, and the rack 1102 is fixed on the left end of the top of the base 1, and the two are meshed with each other. When the supporting rod 8 moves under the push of the electric push rod 4, the shaft rod 10 moves along with it, and due to the meshing relationship between the gear 1101 and the rack 1102, the shaft rod 10 rotates while moving horizontally, and in turn drives the roller brush 14 to roll and move horizontally. The rolling and translating movement of the roller brush 14 can more evenly apply the fixing agent to the surface of the printed matter, effectively avoiding the problem of uneven application of the fixing agent, and significantly improving the quality and effect of the fixing.

[0033] The clamping block one 12 is connected with the roller brush 14 through the clamping groove 13, and the clamping block two 17 is connected with the roller brush 14, which together ensures the firmness of the installation of the roller brush 14, prevents the roller brush 14 from loosening or falling off during the fixing operation, and ensures the smooth progress of the fixing work. The slide rod 18, the spring 22, the adjusting block 21, the through hole 19 and the through groove 16 cooperate with each other, and by rotating the adjusting block 21, the position of the adjusting block 21 on the slide rod 18 can be adjusted through the threaded connection relationship between the tooth 20 and the slide rod 18, and then the spring 22 is compressed or relaxed. The expansion and contraction of the spring 22 drives the movable clamping plate 15 to slide along the slide rod 18 and the supporting rod 8, so that the distance between the fixed clamping plate 9 and the movable clamping plate 15 can be flexibly adjusted according to the actual size of the roller brush 14, and good adaptation to different specifications of the roller brush 14 is realized, and the compatibility of the fixing structure to various roller brushes 14 is improved. During the printing process, the roller brush 14 will be worn, deformed or blocked due to frequent contact with the printing material and the fixing agent, which will affect the fixing effect. The quick detachable design in the structure can quickly remove the roller brush 14 from the equipment, and timely clean, repair or replace it, so as to ensure that the roller brush 14 is always in good working condition, and then ensure the stability of the fixing quality.

[0034] Example 2: as Figure 1 , Figure 3 and Figure 4As shown, the gantry 2 top left and right ends are provided with mounting slot 24, mounting slot 24 inner wall front side is provided with screw hole 25, mounting slot 24 inner wall rear side is provided with sliding slot 29, sliding slot 29 inside is slidably connected with sliding seat 30, the left and right ends of the rear side of the sliding seat 30 are slidably connected with the positioning bolt 31, the rear end of the positioning bolt 31 penetrates the sliding seat 30, the middle end of the positioning bolt 31 is connected with the storage tank 27 through the mounting assembly 26, the front end of the positioning bolt 31 is threadedly connected with the inner wall of the screw hole 25, the transmission assembly 11 includes a gear 1101 and a rack 1102, the gear 1101 is fixedly connected to the left side of the shaft 10, the rack 1102 is fixedly connected to the top left end of the base 1, the gear 1101 is engaged with the rack 1102, the mounting assembly 26 includes a mounting block 2601, the mounting block 2601 is fixedly connected to the bottom center of the storage tank 27, the rear side of the mounting block 2601 is provided with a mounting hole 2602, the inner wall of the mounting hole 2602 is slidably connected with the outer side of the positioning bolt 31, the top of the storage tank 27 is provided with a feed inlet 28, the left and right sides of the spray seat 23 are provided with a hose 32, the top end of the hose 32 is connected with the storage tank 27, the clamping block two 17 is rotatably connected to the bottom end of the left side of the movable clamping plate 15, the movable clamping plate 15 and the clamping block one 12 are both square, the shape of the sliding seat 30 is trapezoidal.

[0035] Specifically, the rear end of the positioning bolt 31 penetrates the sliding seat 30 and is connected with the storage tank 27 through the mounting assembly 26, which not only realizes the reliable connection of the storage tank 27 and the gantry 2, but also enables quick and convenient disassembly when the storage tank 27 needs to be replaced or maintained. When the inside of the storage tank 27 needs to be cleaned, the residual fixing agent, impurities, etc. are removed, or the storage tank 27 itself is overhauled or damaged parts are replaced, it can be conveniently taken off from the gantry, operated in a more suitable environment, improves the maintenance efficiency and reduces the maintenance difficulty. At the same time, when printing some special materials or patterns, different types of roller brushes 14 or storage tanks 27 may need to be replaced. The detachable design enables such adjustment to be quickly completed without the need for large-scale modification of the entire equipment, enhancing the adaptability of the equipment to diversified production needs and providing convenience for the functional upgrade of the equipment. Moreover, two storage tanks 27 can simultaneously store different types of fixing agents. When one fixing agent cannot meet the printing needs during the printing process, without stopping to wait for the replacement of the fixing agent, the other storage tank 27 can be quickly switched to continue the fixing operation, reducing the downtime caused by the replacement of the fixing agent and greatly improving the production efficiency of the printing machine, which is particularly suitable for printing tasks with high requirements for production continuity.

[0036] In the mounting assembly 26, the mounting block 2601 is fixed at the bottom center of the storage tank 27, and the mounting hole 2602 is slidably connected with the outer side of the positioning bolt 31, further ensuring the accuracy and firmness of the installation of the storage tank 27, effectively avoiding displacement or loosening of the storage tank 27 during use, and ensuring the stability of the color fixing agent supply. The feed inlet 28 at the top of the storage tank 27 facilitates the operator to add corresponding color fixing agents into the two storage tanks 27, respectively, and the operation is simple. The design of the square movable clamping plate 15 and the clamping block 12 makes the installation and disassembly of the roller brush 14 more convenient, and during the working process, the square structure can better transmit torque, ensure the stable rotation of the roller brush 14, avoid the rotation deviation or jamming phenomenon caused by unreasonable structure, and improve the reliability and stability of the working of the roller brush 14.

[0037] Working principle: when working, the electric push rod 4 is fixed on the gantry 2 through the fixed plate 3, drives the fixed block 5 to drive the supporting rod 8 to slide in the limiting groove one 6 and the limiting groove two 7, so that the shaft rod 10 moves horizontally and rotates under the action of the transmission assembly 11, drives the roller brush 14 to roll and move horizontally to uniformly apply the color fixing agent; the roller brush 14 is installed between the fixed clamping plate 9 and the movable clamping plate 15 through the clamping block one 12 and the clamping block two 17, and the spacing can be adjusted by the adjusting block 21 to adapt to different specifications of the roller brush 14; the two storage tanks 27 at the top of the gantry 2 are installed through the mounting groove 24, the sliding seat 30, the positioning bolt 31 and the mounting assembly 26, respectively, the color fixing agent in the storage tank 27 is conveyed to the spray seat 23 through the hose 32 and sprayed on the printed matter, and then the roller brush 14 applies it; when one kind of color fixing agent does not meet the demand, the storage tank 27 can be quickly switched, and the storage tank 27 and the roller brush 14 can be quickly disassembled for maintenance and replacement, the whole structure works cooperatively to realize efficient and stable color fixing operation.
