[0016] Please refer to Figures 1-4, the utility model provides a technical solution: an automatic control lifting structure for a printer heavy-duty trolley, including a rear backboard 6, characterized in that a front backboard 3 is arranged on the front surface of the rear backboard 6, air struts 4 are arranged on both sides of the front surface of the front backboard 3, and the bottom end of the air strut 4 is connected to the rear backboard 6. The air strut 4 can assist in lifting the load trolley. A lead screw nut seat 5 is arranged at the top end of the front backboard 3, a limit block 7 is arranged on the right side of the front surface of the rear backboard 6, and the front end of the limit block 7 is connected to the front backboard 3. A lifting stepper motor 2 is arranged at the top end of the lead screw nut seat 5, and the back of the lifting stepper motor 2 is connected to the top end of the rear backboard 6. Support components are arranged on both sides of the front backboard 3, and multiple groups of through grooves are formed on the front surface of the front backboard 3.

[0017] The support component includes a housing 8 fixedly arranged at the outer top end of the front backboard 3. The housing 8 is used to support a rotating rod 9. The rotating rod 9 is rotatably arranged at the center of the housing 8. A pull rope 10 is wound around the outer wall of the rotating rod 9. When the pull rope 10 is wound around the outer wall of the rotating rod 9, it can provide a supporting force for the front of the angle iron 16. A spring 11 is fixedly arranged inside the rotating rod 9. A top block 12 is fitted on the front surface of the spring 11. A top plate 13 is fixedly arranged on the front surface of the top block 12. A limiting strip is processed at the fitting position of the top plate 13 and the rotating rod 9. A caliper 14 is fixedly arranged on the outer wall of the top plate 13 and the inner wall of the housing 8. After the calipers 14 are engaged, they can clamp the rotating rod 9. A push rod 15 is fixedly arranged on the front surface of the top plate 13. The angle iron 16 is detachably arranged at the bottom ends of both sides of the front backboard 3 through bolts, and the outer wall of the angle iron 16 is connected to the other end of the pull rope 10. The caliper 14 on the inner wall of the housing 8 is engaged and connected to the caliper 14 on the outer wall of the top plate 13. A through hole is formed on the outer wall of the housing 8. The pull rope 10 is made of steel cable, and a cavity is formed inside the rotating rod 9.

[0018] Working principle: When the automatic lifting structure of the printer's heavy-duty trolley starts to be used, the user first installs the angle iron 16 on both sides of the front back panel 3 through bolts. Then the user installs the print head at the top of the angle iron 16. After installation, the user pushes the push rod 15 inward. When pushing, it moves inward simultaneously through the top plate 13 and separates the meshing part of the caliper 14. Then it moves inward through the top plate 13 and squeezes the spring 11 through the top block 12. Then when the caliper 14 is completely separated, the user rotates the push rod 15, and then drives the top plate 13 and the rotating rod 9 to rotate simultaneously through the push rod 15. When the rotating rod 9 rotates, it can wind the pulling rope 10 until the pulling rope 10 is wound to a taut state. At this time, the user pulls the push rod 15 forward, and the top block 12 and the top plate 13 are pushed forward simultaneously by the reaction force of the spring 11, and then drives the caliper 14 to engage to limit the top plate 13. When the top plate 13 is limited and cannot rotate, the rotating rod 9 is indirectly calipered by the limiting strip, so that the pulling rope 10 can always be kept in a taut state. By the tension of the pulling rope 10, a supporting force can be effectively provided at the front end of the angle iron 16. When the front back panel 3 moves up and down, the front back panel 3 can be provided with the force for moving up and down through the cooperation of the lifting stepper motor 2, the lead screw nut seat 5 and the air strut 4. Then when the front back panel 3 moves up and down, the limiting block 7 can perform the limiting work.
