DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0021] Please see Figures 1 to 6A feeding device 10 for a roller painting line includes a hopper 20, a turning frame 30, a walking mechanism 40, a clamping mechanism 50, a limiting rail 60, and a control module 70. The lower end of the hopper 20 is connected to the upper end of the turning frame 30, and the lower end of the turning frame 30 is connected to the support seat 304. The walking mechanism 40 is located on both sides of the lower end of the turning frame 30, and the clamping mechanism 50 is located on the inner side of the walking mechanism 40. The upper ends of the walking mechanism 40 and the clamping mechanism 50 are connected to the turning frame 30. The walking mechanism 40 and the clamping mechanism 50 are arranged on the limiting rail 60. The control module 70 is electrically connected to the turning frame 30, the walking mechanism 40, and the clamping mechanism 50. The turning frame 30 includes a front vertical support frame 30. 1. Rear vertical support frame 302, flip cylinder 303, support seat 304, shock absorber 305, the upper end of the front vertical support frame 301 is hinged to the hopper 20, the upper end of the rear vertical support frame 302 is overlapped with the hopper 20, the flip cylinder 303 is located between the front vertical support frame 301 and the rear vertical support frame 302, the upper end of the flip cylinder 303 is hinged to the hopper 20, the lower end of the flip cylinder 303 is hinged to the support seat 304, the support seat 304 is fixedly connected to the upper ends of the front vertical support frame 301 and the rear vertical support frame 302, the front end of the support seat 304 is also fixedly connected to the shock absorber 305, and the support seat 304 is also connected to the upper ends of the walking mechanism 40 and the clamping mechanism 50.

[0022] The hopper 20 of the present invention is used to hold rollers to be painted. When the hopper 20 is in a horizontal state and is located next to the roller silo, the sprocket claw of the roller silo rotates to roll the roller into the hopper 20. In order to enable the hopper 20 to adapt to rollers of different diameters, the cross-section of the hopper 20 is arc-shaped. At the same time, in order to prevent the rollers from being damaged by the impact of the ground when the hopper 20 is turned downward, the hopper 20 is provided with an end face clamping plate at the end of one side of the front vertical support frame 301, and the end face clamping plate is provided with a slot hole to facilitate the rotation shaft of the roller to pass through.

[0023] The turning frame 30 of the present invention is used to turn the hopper 20 from a horizontal state to a vertical state, so that the rollers in the hopper 20 change from a horizontal state to a vertical state, which is convenient for the conveyor chain hanger to hang. When the hopper 20 changes from a horizontal state to a vertical state, the hopper 20 touches the shock absorber 305, and the shock absorber 305 can reduce noise and prevent the hopper 20 from deforming.

[0024] In a preferred embodiment, the main body of the turning frame 30 is welded from square tubes with a side length of 80 mm. The front vertical support frame 301 and the rear vertical support frame 302 are also connected by a cross bar to strengthen the load.

[0025] The walking mechanism 40 of the present invention is used to drive the turning frame 30 and the hopper 20 on the turning frame 30 to move to a predetermined position.

[0026] The clamping mechanism 50 of the present invention is used to ensure the stability of the turning frame 30 during the turning process.

[0027] The control module 70 of the present invention is used to control the automatic operation of the roller spraying line feeding device 10. Specifically, the control module 70 controls the turning of the turning frame 30, and directly controls the turning cylinder 303. Of course, the turning cylinder 303 can also be replaced with an electric push rod.

[0028] Since the rollers are heavy, the hopper 20 will be subjected to a large impact force when it is transferred from the roller silo to the hopper 20. At the same time, the strength of the hopper 20 itself is also relatively high, otherwise the rollers will be deformed.

[0029] Therefore, in a preferred embodiment, the hopper 20 includes a flexible inner lining layer 201, a rigid bottom lining layer 202, an outer covering layer 203, and a reinforcing plate 204. The outer surface of the flexible inner lining layer 201 is bonded to the inner surface of the rigid bottom lining layer 202, and the outer surface of the rigid bottom lining layer 202 is bonded to the inner surface of the outer covering layer 203. The flexible inner lining layer 201, the rigid bottom lining layer 202, and the outer covering layer 203 are fixed by countersunk bolts, and the reinforcing plate 204 is arranged on the outside of the outer covering layer 203.

[0030] The flexible inner lining 201 plays a role of buffering. In a preferred embodiment, the flexible inner lining 201 is made of rubber. The rigid bottom lining 202 and the outer covering layer 203 are made of steel plates of different thicknesses. The reinforcing plate 204 is made of angle steel and is located on both sides of the outer covering layer 203.

[0031] The overturning frame 30 itself has a heavy load-bearing capacity and needs to be accurately moved to a predetermined position. Therefore, a track needs to be laid under the overturning frame 30 .

[0032] In a preferred embodiment, the limiting rail 60 includes a walking rail 601 and an I-shaped rail 602. The walking rail 601 and the I-shaped rail 602 are arranged in parallel. The I-shaped rail 602 is located on the inner side of the walking rail 601. The upper end of the walking rail 601 overlaps with the walking mechanism 40, and the side of the I-shaped rail 602 is engaged with the clamping mechanism 50.

[0033] In a preferred embodiment, the running track 601 is in a T-shape. The width of the upper portion of the running track 601 is the same as the width of the groove of the running wheel 402, so that the running wheel 402 can be stuck on the running track 601 and roll stably.

[0034] In a preferred embodiment, the walking mechanism 40 includes a driving motor 401, a walking wheel 402, and a walking bracket 403. The rotating shaft of the driving motor 401 is connected to the rotating shaft of the walking wheel 402 to drive the walking wheel 402 to rotate. Both ends of the rotating shaft of the walking wheel 402 are mounted on the walking bracket 403, the bottom of the walking wheel 402 overlaps the walking track 601, the upper end of the walking bracket 403 is fixedly connected to the flip frame 30, and the driving motor 401 is electrically connected to the controller 704 module.

[0035] In a preferred embodiment, the clamping mechanism 50 includes a shell 501, an electromagnet 502, a connecting plate 503, a telescopic rod 504, a pad 505, and a clamping wheel 506. The shell 501 is fixedly connected to the flip frame 30, the electromagnet 502 and the connecting plate 503 are located in the shell 501, the connecting plate 503 is located below the electromagnet 502, the upper end of the telescopic rod 504 is fixedly connected to the connecting plate 503, the lower end of the telescopic rod 504 passes through the bottom of the flip frame 30 and is connected to the upper end of the pad 505, the side of the pad 505 is connected to the rotating shaft sleeve of the clamping wheel 506, and the clamping wheel 506 is located in the square groove of the I-shaped track 602.

[0036] When the electromagnet 502 is powered on, the connecting plate 503 is attracted by the electromagnet 502 due to magnetic force, driving the telescopic rod 504 to move upward, so that the clamping wheel 506 is in close contact with the clamping track, ensuring that the flip frame 30 is fixed. When the electromagnet 502 is powered off, under the action of gravity, the connecting plate 503 is disconnected from the electromagnet 502, and the clamping wheel 506 is released. In order to reduce the noise caused by friction and impact, in a preferred embodiment, a rubber ring is provided on the outer surface of the clamping wheel 506, and a spring is provided on the telescopic rod 504.

[0037] In a preferred embodiment, the shock absorber 305 includes a buffer gasket 3051, a buffer rod 3052, and a buffer spring 3053. The buffer gasket 3051 is fixedly connected to the buffer rod 3052, the buffer rod 3052 is horizontally arranged, the buffer spring 3053 is sleeved and connected to the buffer rod 3052, and the buffer rod 3052 is also sleeved and connected to the flip frame 30.

[0038] In a preferred embodiment, the control module 70 includes a proximity switch 701, a first pressure sensor 702, a second pressure sensor 703, and a controller 704. The proximity switch 701 is arranged next to the limit track 60 to detect the position of the flip frame 30. The first pressure sensor 702 is arranged on the shock absorber 305. The second pressure sensor 703 is arranged at the upper end of the rear vertical support frame 302. The proximity switch 701, the first pressure sensor 702, the second pressure sensor 703 and the controller 704 are electrically connected to transmit signals to the controller 704. The controller 704 is also electrically connected to the flip cylinder 303, the drive motor 401, and the electromagnet 502 to control the operation of the flip cylinder 303, the drive motor 401, and the electromagnet 502.

[0039] The first pressure sensor 702 may be disposed on the buffer pad 3051 or at the end of the buffer rod 3052 . In this case, when the buffer rod 3052 hits the flip frame 30 , the first pressure sensor 702 detects a pressure signal.

[0040] When the feeding device 10 on the roller spray painting line moves to a predetermined position, the proximity switch 701 is triggered, and the proximity switch 701 transmits a signal to the controller 704. The controller 704 controls the driving motor 401 of the walking mechanism 40 to stop working. At the same time, the controller 704 controls the electromagnet 502 to be energized, so that the clamping wheel 506 is close to the I-shaped track 602, so that the feeding device 10 on the roller spray painting line stops moving. Then the controller 704 controls the turning cylinder 303 to extend, so that the hopper 20 turns over. When the hopper 20 turns over to a vertical position, it indicates that it has turned over in place. In this process, the worker quickly hangs the roller on the conveyor belt of the spray painting line. At this time, the hopper 20 also happens to touch the shock absorber 305. After the first pressure sensor 702 senses the pressure, it transmits the pressure signal to the controller 704. The controller 704 controls the flip cylinder 303 to contract, so that the hopper 20 changes from a vertical state to a horizontal state. When the hopper 20 touches the second pressure sensor 703, it means that the hopper 20 has been reset. The second pressure sensor 703 transmits the pressure information to the controller 704. The controller 704 controller 704 cuts off the power to the electromagnet 502, so that the clamping wheel 506 moves downward and leaves the I-shaped track 602. At the same time, the controller 704 starts the drive motor 401 to move in the reverse direction to the roller silo. Then the controller 704 controls the driving motor 401 to stop working, and controls the clamping mechanism 50 to make the clamping wheel 506 close to the I-shaped track 602. As the roller is placed on the hopper 20, the pressure on the rear vertical support frame 302 increases, and the second pressure sensor 703 transmits the pressure information to the controller 704. The controller 704 starts the driving motor 401 to make the walking wheel 402 move in the opposite direction. At the same time, the electromagnet 502 is controlled to be powered off, so that the clamping wheel 506 releases the I-shaped track 602. This process repeats.

[0041] During the whole process, workers only need to hang the rollers on the conveyor chain hanger without moving them, which significantly reduces the labor intensity of workers and significantly improves safety. The roller feeding cycle of the spray painting production line feeding device is controlled within 12 seconds, and the daily output can reach 2,000 pieces (8 hours), greatly improving production efficiency.

[0042] What is disclosed above is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
