[0013] A method for using a roll-type thermal self-adhesive label printing machine with an ink roller that automatically detaches when the machine is stopped. S1: Automatically separate the ink roller body from the printing roller, and clean the ink on the ink roller body to prevent it from drying and forming a crust or dirt. When the printing press is suspended, the first servo motor drives the threaded rod to rotate, and the upper end of the threaded rod is connected to the inner side of the upper end of the outer shell frame. The rotation of the threaded rod drives the inner threaded block connected to the outer spiral to move. The inner threaded block drives the metal sliding limit shell, the ink box, the linear spring, the rectangular sliding block and the ink roller body to move at the same time through the second servo motor. The inner threaded block on the left end is slidably connected to the internal sliding rod. When the ink roller body moves ten centimeters, the ink roller body is away from the printing roller, and the second servo motor drives the metal sliding limit shell to rotate one hundred and eighty degrees. The metal sliding limit shell drives the ink box and the ink roller body to rotate one hundred and eighty degrees with the second servo motor main shaft as the axis. At this time, the ink box faces down and the ink roller body faces up. When the upper end of the ink roller body fits with the bottom end of the conveyor belt, the ink The roller body mobilizes the rotationally connected rectangular limit slider to move, and the rectangular limit slider squeezes the linear spring. Under the elastic force of the linear spring, it plays a role of supporting the rectangular limit slider and the ink roller body. At the same time, under the elastic force of the linear spring, it can ensure that the ink roller body is closely fitted with the bottom end of the conveyor belt. At this time, the first servo motor is stopped and the stepper motor is started. The stepper motor drives the inner hollow column roller to rotate, and the inner hollow column roller drives the first gear to rotate. The inner hollow column roller is connected to the inner side of the outer shell frame to improve the stability of the inner hollow column roller during rotation. The rotation of the first gear drives the second gear meshing on the outside to rotate. The second gear drives the conveying roller to rotate. The conveying roller is connected to the inner side of the outer shell frame. The conveying roller drives the conveyor belt to rotate. The conveyor belt drives the auxiliary sleeve roller fitted on the inside to rotate. A polyvinyl alcohol water-absorbing layer is fixed on the outside of the conveyor belt. When the conveyor belt rotates, the ink on the outside of the ink roller body can be absorbed. S2: When cleaning the ink on the outside of the conveyor belt, the water pump pumps water from the water tank, and the water enters the outer shell frame from the water pump. The inner side of the outer shell frame fits with the outer side of the inner hollow column roller through the sealing ring. The water enters the water inlet channel from the outer shell frame, enters the humidification port from the water inlet channel, and is sprayed to the cotton strip from the humidification port. At this time, the cotton strip is in a wet state. According to the above principle, the stepper motor is started to drive the inner hollow column roller to rotate. The rotation of the inner hollow column roller causes the cotton strip fixed on the outside to rotate. Under the action of centrifugal force, the cotton strip contacts the outer side of the conveyor belt, and the cleaned water falls into the inside of the waterproof board and flows out from the outflow port. At the same time, the hot air blower is started, and the hot air blower blows hot air into the hot air outlet slot opened in the blow box, and blows it to the outside of the conveyor belt from the rear end of the hot air outlet slot. S3: When printing the thermal self-adhesive label on the outside of the winding roller and the passive drum, to prevent the thermal self-adhesive label from being skewed and causing the printing quality to be handed over, the winding roller is driven to rotate by an external driving device, and the winding roller rewinds the thermal self-adhesive label. The thermal self-adhesive label is sleeved on the outside of the passive drum, and the passive drum rotates under the tension of the thermal self-adhesive label, and the thermal self-adhesive label passes between the printing roller and the auxiliary roller. The ink roller body inks the printing roller, and the thermal self-adhesive label is printed through the printing roller. The inner side of the passive drum rotates and is connected to the outer side of the fixed column arm. When the passive drum rotates, the triangular block continuously slides out of the triangular slot and fits in other triangular slots. In this process, the spring continuously accumulates elastic force. Under the torsion of the spring, it can be ensured that the passive drum has a certain torque when it rotates, so that the thermal self-adhesive label can be controlled to always remain in a tensioned state.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the first servo motor, threaded rod, ink roller body, printing roller and rectangular limit slider are set, and the device controls the first servo motor to start through the controller. The first servo motor drives the threaded rod to rotate, so as to realize the automatic separation of the ink roller body and the printing roller, and prevent the ink from drying and forming a hard crust or dirt on the surface of the ink roller. This automatic separation mechanism reduces manual intervention, improves the convenience of operation and the automation of the machine, and the second servo motor drives the metal limit slide shell to rotate 180 degrees, so that the ink box faces down and the ink roller body faces up. The ink roller body continues to move upward and fits with the bottom of the conveyor belt. The rectangular limit slider squeezes the linear spring, and uses the elastic force of the linear spring to ensure that the ink roller body is closely fitted with the bottom of the conveyor belt. The stepper motor is started to drive the inner hollow column roller to rotate, and the inner hollow column roller drives the first gear to rotate. The polyvinyl alcohol water absorption layer on the outside of the conveyor belt absorbs the ink on the outside of the ink roller body and cleans it. This step not only cleans the ink roller, but also prevents the ink from drying through the polyvinyl alcohol water absorption layer, ensuring the printing performance of the ink roller and the quality of re-printing; 2. In the present invention, by means of the water pump, outer shell frame, water inlet channel, humidification port and hot air blower, the device starts the water pump to pump water from the water tank, and water enters the outer shell frame from the water pump, and then enters the humidification port from the water inlet channel, and is sprayed onto the cotton strips to wet the cotton strips. The stepper motor is started to drive the inner hollow column roller to rotate, and the cotton strips contact the outer side of the conveyor belt under the action of centrifugal force to clean the ink on the outer side of the conveyor belt. This step effectively cleans the ink on the outer side of the ink roller through the wetting of water and the action of centrifugal force to keep the ink roller clean. The hot air blower is started to blow hot air into the hot air outlet slot provided in the blow box, and blows hot air from the rear end of the hot air outlet slot to the outside of the conveyor belt to quickly dry the polyvinyl alcohol water-absorbing layer on the outside of the conveyor belt. This drying step ensures that the ink roller can quickly return to a dry state after cleaning, and reduces the re-contamination or drying of the ink caused by moisture. 3. In the present invention, the passive rotating drum, the fixed column arm, the triangular block and the spring groove are arranged, and the winding roller is driven to rotate by an external driving device, and the winding roller winds up the thermal self-adhesive label. The thermal self-adhesive label is sleeved on the outside of the passive rotating drum, and the inner side of the passive rotating drum is connected to the outer side of the fixed column arm by rotation. The triangular block continuously slides out of the triangular groove and fits inside other triangular grooves. The clockwork spring accumulates elastic force to ensure that the passive rotating drum has a certain torque when rotating. This control mechanism ensures that the thermal self-adhesive label always remains in a tensioned state during the printing process, prevents the label from being skewed, and thus improves the printing quality and accuracy.

The first gear 56 rotates to drive the outer gear The second gear 41 rotates, and the second gear 41 drives the conveying roller 42 to rotate. The conveying roller 42 is rotatably connected to the inner side of the outer shell frame 21 to ensure the stability of the conveying roller 42 when it rotates. The conveying roller 42 drives the conveying belt 43 to rotate, and the conveying belt 43 drives the auxiliary sleeve roller 44 attached to the inner side to rotate. A polyvinyl alcohol water-absorbing layer is fixed on the outer side of the conveying belt 43. When the conveying belt 43 rotates, it can absorb the ink on the outer side of the ink roller body 79 and clean the ink roller body 79 at the same time, so as to prevent the ink on the outer side of the ink roller body 79 from drying and forming a hard crust or dirt, thereby ensuring that the printing performance of the ink roller body 79 is not affected and improving the quality of reprinting; When cleaning the ink on the outside of the conveyor belt 43, the water pump 23 is started, and the water pump 23 pumps water from the water tank 22. The water enters the outer shell frame 21 from the water pump 23. The inner side of the outer shell frame 21 is fitted with the outer side of the inner hollow column roller 52 through a sealing ring, which plays a role in sealing the outer shell frame 21 and the inner hollow column roller 52 to prevent water from overflowing to the outside. The water enters the water inlet channel 53 from the outer shell frame 21, and enters the humidification port 54 from the water inlet channel 53, and is sprayed to the cotton strip 55 from the humidification port 54. At this time, the cotton strip 55 is in a wet state. According to the above principle, the stepper motor 51 is started to drive the inner hollow column roller 52 to rotate, and the inner hollow column roller 52 rotates and is fixedly connected to the outside. The cotton strip 55 rotates, and under the action of centrifugal force, the cotton strip 55 contacts the outer side of the conveyor belt 43, and the cotton strip 55 is used to clean the ink on the outer side of the conveyor belt 43. The cleaned water falls into the interior of the waterproof plate 24 and flows out from the outflow port 25. The waterproof plate 24 can prevent the cleaned water from entering the lower part of the outer shell frame 21 and affecting other devices. At the same time, the hot air blower 34 is started, and the hot air blower 34 blows hot air into the hot air outlet slot 33 provided in the blowing box 32, and blows hot air from the rear end of the hot air outlet slot 33 to the outer side of the conveyor belt 43, thereby quickly drying the polyvinyl alcohol water absorption layer on the outer side of the conveyor belt 43, so as to facilitate the cleaning of the ink roller body 79 at this time. When printing the thermal self-adhesive label on the outside of the winding roller 1 and the passive drum 61, in order to prevent the thermal self-adhesive label from being skewed and causing the printing quality to be changed, the winding roller 1 is driven to rotate by an external driving device, and the winding roller 1 rewinds the thermal self-adhesive label. The thermal self-adhesive label is sleeved on the outside of the passive drum 61. Under the action of the tension of the thermal self-adhesive label, the passive drum 61 rotates, and the thermal self-adhesive label passes between the printing roller 27 and the auxiliary roller 28. The ink roller body 79 inks the printing roller 27, and the thermal self-adhesive label is printed through the printing roller 27. The inner side of the passive drum 61 is rotatably connected to the outer side of the fixed column arm 64, which plays a role in limiting the rotation of the passive drum 61. When the passive drum 61 rotates, the triangular block 66 continuously slides out of the triangular slot 63 and fits into other triangular slots 63. During this process, the spring 65 continuously accumulates elastic force. Under the torsion of the spring 65, it can be ensured that the passive drum 61 has a certain torsion when rotating, so that the thermal self-adhesive label can be controlled to always remain in a tensioned state, thereby ensuring the quality of the printing roller 27 when printing the thermal self-adhesive label.
