Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a feeding device for a powder spraying production line. Background Technology

[0002] Powder coating is a coating process that uses corona discharge to adhere powder coatings to workpieces. After powder coating, the workpiece undergoes hot melting and curing processes to form a coating film on the workpiece surface. In order to improve production efficiency, a feeding device is needed to feed the workpieces during the production process. However, there are still some problems with the existing feeding devices.

[0003] Existing patent applications, such as Chinese Patent Application No. CN201921311548.2, describe a brake pad powder coating line with an automatic feeding mechanism, relating to the field of powder coating line technology. The line includes a worktable, a rotating lifting seat, a cylinder, a conveyor belt, a powder coating device, a drive motor, a collection tank, and an adsorption device. The top of the worktable is fixedly connected to the bottom of the rotating lifting seat, and a cylinder is fixedly installed at the bottom of the rotating lifting seat. A conveyor belt is fixedly installed on the top of the worktable, and the outer wall of the conveyor belt engages with the inner wall of the collection tank. The outer wall of the powder coating device is fixedly connected to the outer wall of the rotating lifting seat. A drive motor is fixedly installed at the bottom of the worktable, and an adsorption device is fixedly installed at the bottom of the cylinder. However, the feeding structure of this existing powder coating production line is difficult to maintain stable feeding during use. When the workpiece is conveyed above the conveyor belt, manual feeding is required, and it is difficult to change the direction, making reliable and stable feeding difficult to achieve.

[0004] Therefore, we propose a feeding device for a powder coating production line to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding device for a powder spraying production line, so as to solve the problem mentioned in the background art that the feeding structure of the existing powder spraying feeding line is difficult to change direction and difficult to achieve stable and reliable feeding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for a powder coating production line, comprising a support frame:

[0007] A first transmission belt is fixed to the upper left side of the support frame, and a second transmission belt is fixed to the upper right side of the support frame. A first guide plate is provided at the upper end of the first transmission belt, and a second guide plate is provided on the side of the first guide plate. A limiting plate is provided on the right side of the second guide plate.

[0008] Electric slides are fixed to the upper ends of both sides of the first transmission belt, and sliders are connected to the upper ends of the electric slides. A movable frame is fixed to the upper end of the sliders. A movable plate is provided in the middle of the movable frame, and a diverter is fixed to the lower end of the movable plate. A guide pipe is connected to the lower end of the diverter, and a suction cup is connected to the lower end of the guide pipe.

[0009] A sealing tube is fixed to the upper end of the movable plate, and a piston is installed inside the sealing tube.

[0010] Preferably, the upper ends of the first and second transmission belts are flush, and the first and second transmission belts are distributed in an "L" shape.

[0011] By adopting the above technical solution, the workpiece transfer direction can be changed through the flush design of the first and second transmission belts and the transfer structure.

[0012] Preferably, the first guide plates are symmetrically distributed on the front and rear sides of the first transmission belt, and the first guide plates are fixed to the side of the first transmission belt. Positioning plates are fixed on the upper part of the two sets of first guide plates, and the upper part of the second guide plate is fixed to the positioning plate. The right side ends of the first guide plates and the second guide plates are both fixed to the limiting plate.

[0013] By adopting the above technical solution, through the cooperation between the first guide plate and the second guide plate, the workpiece can move into the gap between adjacent parts during the conveying process, and the movement of the workpiece can be further restricted by the limiting plate.

[0014] Preferably, the second guide vane has an "A" shaped structure and is distributed in an equidistant array.

[0015] By adopting the above technical solution, the second guide plate with an A-shaped design facilitates the movement of the workpiece within the adjacent gaps.

[0016] Preferably, the slider is slidably connected to the electric slide table, and the right side of the electric slide table extends to the upper end of the second transmission belt. The guide tube and the suction cup are distributed in an equidistant array. The upper ends of both sides of the movable frame are fixed with first electric push rods, and the lower ends of the first electric push rods are fixed to the movable plate.

[0017] By adopting the above technical solution, the electric slide can drive the movable plate to rise and fall, and the movable frame can drive the guide tube, suction cup and diverter tube to rise and fall, so that the suction cup can contact the workpiece and then adsorb it. At the same time, the cooperation of the electric slide and the slider can move the position of the suction cup.

[0018] Preferably, the sealing tube is slidably connected to the piston, the front end of the sealing tube is connected to a guide tube, and the lower end of the guide tube is connected to the diverter tube. A second electric push rod is fixed to the rear side of the sealing tube, and the front end of the second electric push rod is fixed to the piston.

[0019] By adopting the above technical solution, through the cooperation of the piston and the sealing tube, when the second electric push rod extends or retracts, it can drive the piston and the inside of the sealing tube to move. When the piston moves, it can draw the air inside the diversion tube, the guide tube and the suction cup into the sealing tube, so that the inside of the suction cup is in a negative pressure state, thereby achieving adsorption of the workpiece.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the powder spraying production line uses a feeding device;

[0021] 1. By setting up multiple sets of transmission belt structures and cooperating with the transfer structure, it is possible to realize the conveying of workpieces in the transfer direction, and with the help of the limiting structure, it is possible to position and transfer the workpieces, keep the workpieces conveyed at equal distances, ensure stable feeding, and improve the quality of subsequent powder spraying operations.

[0022] 2. By setting up a piston in conjunction with a second electric push rod structure, the suction cup can be controlled to be in a negative pressure state. After the suction cup comes into contact with the workpiece, it can adsorb the workpiece and transfer the workpiece when the electric slide table drives the slider to move. It can change the feeding direction of the workpiece and maintain the workpiece feeding at a constant distance and speed. Attached Figure Description
