The guide rod is arranged along one side of the limiting frame. When in use, one end of the frame rear column body is pressed against the second inner ring, and the electric telescopic rod is opened so that the guide slider drives the first outer ring The first outer ring moves so that the first inner ring abuts against the other end of the rear column body of the frame, thereby fixing the position of the rear column body of the frame, and when the first inner ring moves, the L-shaped connecting rod can be embedded in the inner side of the L-shaped connecting sleeve. After the spray head moves to spray the rear column body of the frame, the L-shaped connecting sleeve and the L-shaped connecting rod are rotated to rotate the second inner ring and the first inner ring.

When the sequential spraying operation of the rear column body 1 of the frame is carried out, when paint gathers on the bottom positioning plate 14, it can be discharged externally to avoid the accumulation of paint on the positioning plate affecting the normal spraying operation of the rear column body 1 of the frame.

[0024] It should be further explained that the operating system includes a central tube frame 15, the inner gear ring 12 is fixedly connected to the central tube frame 15 through a plurality of umbrella support rods, the central tube frame 15 is fixedly connected to the main frame 2, and two mounting ports are provided on the central tube frame 15, and an air guide shell 16 and a spray shell 17 are respectively installed in the two mounting ports, a plurality of jet ports 18 are arranged on the air guide shell 16, and a plurality of nozzles 19 are arranged on the spray shell 17, and the plurality of nozzles 19 are all equipped with air inlets, and the plurality of air inlets are gradually lowered downward from the inside to the outside of the spray shell 17, and the plurality of air inlets are arranged downwardly. The central cylinder frame 15 is provided with a piping system, which includes a hot air guide pipe 34, a paint guide pipe 35 and a compressed air guide pipe 36.

[0025] The servo motor 4 in this embodiment is a conventional device purchased on the market and known to those skilled in the art. It is necessary to select or customize the corresponding model according to actual needs. In this patent, we only use it and do not improve its structure and function. For the technicians in this field, the setting method, installation method and electrical connection method only need to be debugged according to the requirements of its instruction manual, and will not be described in detail here.

[0026] In summary, the working process of the forklift frame rear column spraying equipment is as follows: when in use, first place the forklift frame rear column spraying equipment at the desired location, and connect the servo motor 4 to the control circuit according to its supporting instructions, and then connect the hot air guide pipe 34, the paint guide pipe 35 and the compressed air guide pipe 36 to the external hot air supply equipment, the paint supply equipment and the compressed air supply equipment through three quick-connect pipes 45 to form a connection, so that the air jet 18 can spray dry hot air, the nozzle 19 can spray mist paint, and the air inlet can spray clean compressed air. In the actual operation process, first start the servo motor 4, and the servo motor 4 works to realize the slow rotation drive of the rotating shell 3 relative to the main frame 2. When the multiple step operating ports 5 on the rotating shell 3 sequentially rotate through the limit protection frame 46, they will rotate to the limit protection frame. The top frame 8 in the stepped working opening 5 in the guard frame 46 is lifted. The process of lifting the top frame 8 is that the operator first holds the lifting ring 40 and pulls the sliding frame 9 in the direction close to the limit protection frame 46 relative to the top frame 8, so that the relative meshing action between the gear frame 11 connected to the sliding frame 9 and the internal gear ring 12 is invalidated, and then maintains the invalid state, and lifts the structure composed of the lifting frame 7, the top frame 8 and the bottom frame 13 as a whole through the lifting ring 40. During the lifting process, the lifting frame 7 is gradually raised. When it is not convenient to lift it through the lifting ring 40, the height of the lifting frame 7 can be assisted by the force-applying hand groove 44 on the lifting frame 7. When the lifting frame 7 is raised to an appropriate height, the rear column body 1 of the frame that needs to be painted is placed in the area between the bottom positioning plate 14 and the top positioning plate 22 in the lifting frame 7.

[0027] Furthermore, in order to facilitate the centering and alignment of the rear column body 1 of the frame relative to the bottom positioning plate 14, the top end of the bottom positioning plate 14 is a concave conical groove structure, and before the rear column body 1 of the frame is placed between the bottom positioning plate 14 and the top positioning plate 22, it is necessary to push the cross bar 43 upward relative to the lifting base frame 7. Under the transmission action of the auxiliary lifting bent cylinder 41 and the sliding bent rod 42, the height of the lifting rod 20 relative to the sliding frame 9 is lifted, prompting the rotating rod 21 and the top positioning plate 22 to form a height increase, that is, the relative height between the top positioning plate 22 and the bottom positioning plate 14 is increased to facilitate the insertion of the rear column body 1 of the frame. After the insertion is completed, the cross bar 43 pushed relative to the lifting base frame 7 is released. Under the action of the tension spring 24, the top positioning plate 22 is lowered relative to the bottom positioning plate 14. In this way, the limiting of the rear column body 1 of the frame placed between the top positioning plate 22 and the bottom positioning plate 14 can be achieved, and then the lifting base frame 7 is controlled to be relatively As for the step working opening 5 falling down, until the gear frame 11 re-forms the relative meshing effect with the inner gear ring 12, when the gear frame 11 is about to re-form the relative meshing with the inner gear ring 12, it is still necessary to first pull the sliding frame 9 close to the limit protection frame 46 to realize the gear frame 11 to move away from the inner gear ring 12. Then, when the gear frame 11 and the inner gear ring 12 reach the same meshing height, the push on the sliding frame 9 is released, and under the action of the elastic spring 10, the gear frame 11 can be approached to the inner gear ring 12, and then the relative meshing effect is formed, thereby completing the installation of a single frame rear column body 1 into the partition chamber 6. Along with the operation of the servo motor 4, the rotating shell 3 moves slowly, and the aforementioned operating steps are repeated in sequence to realize the sequential installation of multiple frame rear column bodies 1 into the rotating shell 3. Since the movement of the rotating shell 3 is relatively slow, it does not affect the loading operation of the frame rear column body 1.

[0028] Furthermore, the rear column body 1 of the frame installed in the rotating shell 3 will be driven to rotate under the relative meshing action between the inner gear ring 12 and the gear frame 11, so that multiple rear column bodies 1 of the frame can be synchronously rotated relative to the rotating shell 3 and can also rotate in the rotating shell 3. The fitting surfaces of multiple compartments 6 and the central cylinder frame 15 are provided with strip openings. When the strip openings coincide with the air jets 18, dry air will enter the compartment 6 to dry the rear column body 1 in the compartment 6. When the strip openings coincide with the spray nozzles 19, atomized paint will enter the compartment 6 to spray the rear column body 1 in the compartment 6, and the paint sprayed into the compartment 6 due to gravity. It will fall under the action of its own gravity, so the air inlet matched with the nozzle 19 will form an auxiliary blowing close to the falling paint relative to the frame rear pillar body 1 through compressed air to improve the effective utilization rate of the paint, and along with the continuous rotation of the rotating shell 3, the frame rear pillar body 1 forms a self-rotation in the corresponding partition chamber 6 to achieve full coverage of the circumferential painting and full coverage of drying of the frame rear pillar body 1, and the operation sequence of the frame rear pillar body 1 should be the sequence of spraying first and then drying. When the dried frame rear pillar body 1 is transferred into the limiting protection frame 46 again, the frame rear pillar body 1 that has been sprayed can be taken out, and the frame rear pillar body 1 that needs to be sprayed can be loaded again at the corresponding position where it was taken out.
