A motor device for driving the suspension rod 31 to rotate is provided inside the drive box 3, which is used to rotate and adjust the angle of the aluminum material after hoisting.

[0022] A hook 41 is provided on the lower side of the suspension rod 31 for hoisting the aluminum material. A spring tube 4 is installed on the lower end surface of the suspension rod 31. The hook 41 is installed at the lower end of the spring tube 4. A wire reel 5 is provided inside the drive box 3. A pull rope 51 is wound around the surface of the wire reel 5. The lower end of the pull rope 51 is connected to the upper surface of the hook 41. The cooperation of the wire reel 5 and the pull rope 51 is used to adjust the compression strength of the spring tube 4. A pressure sensor 6 is provided at the lower end of the spring tube 4. A motor module 32 for driving the wire reel 5 to rotate is installed inside the drive box 3. The pressure sensor 6 is electrically connected to the motor module 32.

[0023] The loading box 7 is located below the hoisting bracket 1. An opening is provided on the surface of the loading box 7 on one side along the conveying direction of the conveying chain 11. After the aluminum material is hoisted, it is lifted out of the loading box 7 through the opening. Two guide plates 71 are provided on the upper surface of the loading box 7. A notch is provided between the two guide plates 71. The notch is adapted to the hook 41. The two guide plates 71 are slidably installed along the width direction of the upper surface of the loading box 7. According to the hoisting points on the surface of the aluminum material, the positions of the guide plates 71 can be adjusted, so as to guide the hook 41.

[0024] A guide groove 72 is provided on the lower surface of the guide plate 71. The guide groove 72 corresponds to the notch. One end of the guide groove 72 close to the loading belt 9 is inclined obliquely upward, which is convenient for guiding the hook 41 to the position of the hoisting point on the surface of the aluminum material, and is beneficial to improving the hoisting accuracy of the hook 41.

[0025] The feeding belt 8 is horizontally installed inside the loading box 7 and is used for horizontally feeding and conveying the aluminum material. Partition plates 81 are provided on the surface of the feeding belt 8 for placing the aluminum material and at the same time facilitating the pushing of the aluminum material onto the surface of the push plate 91; the loading belt 9 is vertically installed inside the loading box 7 and corresponds to the position of the opening on the surface of the loading box 7, and is used for upwardly conveying a single aluminum material, which is convenient for the hook 41 to hoist the aluminum material. The loading belt 9 is located on one side of the feeding belt 8 in the feeding direction. A push plate 91 is provided on the surface of the loading belt 9 for pushing the aluminum material to move.

[0026] There are two groups of feeding belts 8, and a gap is left between the two groups of feeding belts 8. The loading belt 9 is located between the gaps at one end of the two groups of feeding belts 8 in the feeding direction, which is convenient for conveying the aluminum material from the surface of the feeding belt 8 to the push plate 91 on the surface of the loading belt 9.

[0027] The lower half of the feeding tape 9 near the feeding side of the feeding belt 8 is vertically distributed, and the upper half is inclined obliquely upward along the feeding direction of the feeding belt 8 to prevent the aluminum material from falling backward. An auxiliary baffle 73 is provided inside the feeding box 7. The auxiliary baffle 73 is located above one end of the feeding belt 8 in the feeding direction. An arc-shaped surface is provided on one side of the auxiliary baffle 73 close to the inclined surface of the feeding tape 9 to facilitate the aluminum material to incline onto the surface of the feeding tape 9.

[0028] Working principle of the hoisting system: When batch painting of aluminum materials is required, first place the aluminum materials to be painted on the surface of the feeding belt 8 inside the feeding box 7, with the liftable side of the aluminum material facing away from the feeding tape 9. The feeding belt 8 can be used to convey the aluminum materials to the position of the feeding tape 9. When the feeding tape 9 rotates, when the push plate 91 on the surface of the feeding tape 9 moves to the position of one end of the feeding belt 8 in the feeding direction, the aluminum materials are conveyed to the surface of the push plate 91 under the conveying action of the feeding belt 8. As the feeding tape 9 rotates, the push plate 91 pushes the aluminum materials upward.

[0029] When the aluminum materials move upward, under the action of the auxiliary baffle 73, the aluminum materials incline along the upper half surface of the feeding tape 9 and continue to move upward until the lifting points on the surface of the aluminum materials move to the upper port position of the guide groove 72.

[0030] Through relevant drive control, the conveyor chain 11 moves. The conveyor chain 11 drives the mounting seat 2 to move together. The mounting seat 2 drives the spring tube 4 and the hook 41 to move together through the drive box 3 and the suspension rod 31. When the hook 41 does not hook the aluminum material, the spring tube 4 is in an uncompressed state at this time. When the hook 41 moves to the position of the feeding box 7, under the action of the two guide plates 71, the hook 41 will enter the guide groove 72 and move in the guide groove 72. Under the action of the guide groove 72, the hook 41 finally moves out from the upper port of the guide groove 72 and hooks the aluminum material.

[0031] After the hook 41 hooks the aluminum material and takes the aluminum material away from the feeding box 7, at this time, the pressure sensor 6 senses the change in the elastic force of the spring tube 4 and transmits the signal to the motor module 32. The motor module 32 starts and drives the winding drum 5 to rotate. The winding drum 5 winds up the pulling rope 51. The pulling rope 51 drives the hook 41 to move upward, and uses the upper surface of the hook 41 to compress the spring tube 4, so that the spring tube 4 is in a compressed state. At this time, the compression elastic force of the spring tube 4 increases, and the spring tube 4 tends to be in a straight tube shape, so as to avoid the shaking of the aluminum material. As the conveyor chain 11 moves, the hook 41 will drive the aluminum material to move to the painting area to paint the aluminum material.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
