[0035] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0036] like Figures 1-6 As shown, a large-lift arm automatic coating production line includes a frame 1, a lifting drive mechanism 2, a trough body 3, a roller 4, a lifting large-lift arm 5, a transverse trolley 6, a material trolley 7, a positioning cylinder 8, an electric cabinet 9 and a limit mechanism 10.

[0037] A plurality of adjusting feet 101 are provided at intervals on the bottom of the rack 1 , and the rack 1 is adjusted by the adjusting feet 101 .

[0038] There are multiple trough bodies 3, and multiple trough bodies 3 are arranged in the frame 1. The trough bodies 3 are used to place rollers 4. The lifting arm 5 is arranged in the frame 1, and each trough body 3 has a work station. The lifting arm 5 is arranged above the trough body 3. A lifting drive mechanism 2 is arranged on the top of the frame 1, and the lifting arm 5 is driven to rise and fall by the lifting drive mechanism 2. Two lifting drive mechanisms 2 can be provided, and the two lifting drive mechanisms 2 are symmetrically arranged. A guide rail 501 is arranged on the inside of the lifting arm 5, and a transverse trolley 6 is arranged in the lifting arm 5. Rollers 601 are arranged on both sides of the transverse trolley 6. The rollers 601 are arranged in the guide rail 501, so that the trolley can move along the guide rail 501. A bracket 602 is arranged on the top of the transverse trolley 6. The bracket 602 is connected to the cylinder 11. The other end of the cylinder 11 is fixedly connected to the frame 1, and the transverse trolley 6 is driven to move by the cylinder 11. A plurality of second lifting ears 603 are provided at the bottom of the transverse moving trolley 6 , and the first lifting ears 401 of the drum 4 are driven to move by the second lifting ears 603 , thereby driving the drum 4 to move.

[0039] The frame 1 can be made of Q235 H steel profile, and the adjustment foot 101 can be made of M24-150 galvanized steel. An electric cabinet 9 is provided on one side of the frame 1, and power is supplied through the electric cabinet 9.

[0040] The lifting drive mechanism 2 includes a motor 201, a reducer 202, a rotating shaft 203, a rotating frame 204, a cloth belt 205 and a connecting rod 206. The motor 201 is arranged on the frame 1, and the output shaft of the motor 201 is connected to the input shaft of the reducer 202. The output shaft of the reducer 202 is connected to the rotating shaft 203. A rotating frame 204 is arranged on the rotating shaft 203. A cloth belt 205 is wrapped around the rotating frame 204. One end of the cloth belt 205 is fixedly connected to the rotating frame 204, and the other end of the cloth belt 205 is fixedly connected to the connecting rod 206. The connecting rod 206 is fixedly connected to the lifting arm 5.

[0041] The motor 201 drives the rotating shaft 203 to rotate through the reducer 202, and the rotating shaft 203 drives the rotating frame 204 to rotate. The rotating frame 204 winds or loosens the cloth belt 205, thereby driving the lifting arm 5 to rise or fall. The lifting and lowering of the lifting arm 5 is controlled by the forward and reverse rotation of the motor 201.

[0042] The drum 4 is provided with an openable cover, which is opened when loading and closed after loading is completed.

[0043] One end of the frame 1 is the loading area, and the other end of the frame 1 is the unloading area. The frame 1 is provided with positioning cylinders 8 on both sides of the loading area and the unloading area. The material trolley 7 can be placed in the loading area and the unloading area of ​​the frame 1. The material trolley 7 is used to place the roller 4. A mounting plate is provided on the material trolley 7, and a through hole is provided on the mounting plate. One end of the positioning cylinder 8 can be extended into the through hole to lock the material trolley 7.

[0044] The limiting mechanism 10 includes a limiting column 1001, a connecting frame 1002, and a limiting wheel 1003. The limiting column 1001 is fixed to the frame 1, the connecting frame 1002 is fixed to the lifting arm 5, and there are multiple limiting wheels 1003, which can be three. The multiple limiting wheels 1003 are arranged in different directions of the limiting column 1001 for limiting. When the lifting arm 5 moves, the lifting arm 5 drives the limiting wheel 1003 to move along the limiting column 1001 through the connecting frame 1002, thereby limiting the lifting arm 5 and preventing the lifting arm from shaking too much during movement.

[0045] During specific use, a roller 4 is placed on the material trolley 7, the cover of the roller 4 is opened to load the material, and the cover of the roller 4 is closed after loading. The material trolley 7 is pushed to the loading area of ​​the frame 1, and then the material trolley 7 is locked by the positioning cylinder 8. The lifting drive mechanism 2 drives the lifting arm 5 to descend to the lowest point, and the lifting arm 5 drives the transverse trolley 6 to descend, and the cylinder 11 drives the transverse trolley 6 to move along the guide rail 501 of the lifting arm 5, so that the second lifting ear 603 of the transverse trolley 6 is completely under the first lifting ear 401 of the roller 4, and the lifting drive mechanism 2 drives the lifting arm 5 to rise, and the lifting arm 5 drives the transverse trolley 6 to move. The trolley 6 rises, and the transverse trolley 6 drives the roller 4 upward via the first and second lifting eyes 401 and 603. After the roller 4 is raised to its proper position and the bottom of the roller 4 is higher than the top of the tank 3, the cylinder 11 is activated, driving the transverse trolley 6, which in turn drives the roller 4. After the roller 4 moves to the next station, the lifting drive mechanism 2 drives the lifting arm 5 downward, dropping the roller 4 into the tank 3. The cylinder 11 drives the transverse trolley 6 until the second lifting eye 603 of the transverse trolley 6 is clear of the first lifting eye 401 of the roller 4. The lifting drive mechanism 2 drives the lifting arm 5 upward, and the cylinder 11 drives the transverse trolley 6 back to its initial position. The above operation is repeated until there is a roller 4 in each station of the tank 3. In the next repetition, a material trolley 7 is locked in the unloading area of ​​the frame 1 via the positioning cylinder 8. The roller 4 in the last tank 3 falls back onto the material trolley 7 in the unloading area. The material trolley 7 is removed to complete the feeding process.

[0046] The machine utilizes a large lifting arm structure, with a central cylinder 11 driving the traverse trolley 6 for stepping motion. The lifting drive mechanism 2 drives the lifting arm 5 for lifting motion. Multiple material trolleys 7 and rollers 4 are used to transfer loading and unloading offline, without affecting the production line cycle, thereby improving efficiency and production capacity.
