Description

[0002] Spraying machine equipment is used to spray surface structures such as coatings on the surface of products. Currently, the processing efficiency is generally low. The reasons are as follows: on the one hand, it is necessary to spray all surfaces of the product; on the other hand, after spraying, it is also necessary to remove the excess liquid completely. Due to these two factors, the current traditional method is to spray single products. In order to improve the processing efficiency, it is necessary to spray multiple products simultaneously.

[0044] The drying structure 600 includes: an oven 610 and a conveyor belt 620, and the conveyor belt 620 is arranged inside the oven 610.

[0045] The process of the present invention is as follows: The feeding structure transports the product to be processed from the stacking table, and at the end, the feeding manipulator 200 puts the material into the material distribution device 300. Then the material distribution device 300 sends the product into the spraying structure. With the annular module 410 as the center, the product is sprayed during the transmission process, and then flipped to remove the excess coating solution by gravity. Finally, after scraping the solution on the surface clean by the air knife machine 470, the product is sent into the conveyor belt 620 by the transfer manipulator 500 to start baking.

[0046] Among them, the feeding structure 100, the feeding manipulator 200, the transfer manipulator 500, and the drying structure 600 are all existing equipment, and their structures and principles will not be elaborated here. Therefore, the innovation points of the present invention are reflected in the material distribution device 300 and the spraying structure 400. The spraying structure can process multiple products simultaneously in a production line manner, and at the same time, the fixed gripper 430 cooperates with the track drop of the circular module 410 to achieve flipping, so that the solution can be removed within a single plane. In order to achieve the above functions, it is necessary to be equipped with a material distribution device 300 with fast and sufficient feeding capacity.

[0047] The material distribution base 310 in the material distribution device 300 is used to fix other structures and provide sufficient height to cooperate with other workstations. The placement rack 320 is used to stack products. The limit posts 322 are respectively fixed at the four corners of the material stacking plate 321 to fix the products by means of limitation. In this embodiment, there are two groups of placement racks 320, which can greatly improve the overall feeding efficiency. However, such a narrow space may cause collisions and conflicts between structures. Therefore, during the design process of the placement rack 320, it is movable. Therefore, the placement rack 320 is connected to the material distribution transmission system 330 through the placement rack connecting shaft 323. The function of the material distribution transmission system 330 is to drive the placement rack 320 to move, so as to achieve cyclic feeding. The principle is that the rotating fixing plate 331 is used as a fulcrum, and at the same time, an external motor drives the rotating fixing plate 331 to rotate through a shaft. The other end of the rotating fixing plate 331 is connected to the rotating moving fixing plate 332 through a shaft. The rotating moving fixing plate 332 moves on the material distribution transmission slide rail 333, and at the same time, the transmission shaft moves along the moving groove 335. The shape of the moving groove 335 is designed to meet the moving track of the transmission shaft to prevent it from colliding with other structures. Such a structure can enable the two placement racks 320 to share the feeding position without collision, thereby improving the feeding efficiency.

[0048] After that, the inner bottom of the downward-facing product is sucked by the suction cup structure 350. Then, the feeding system 340 uses motors to move the first clamping plate 343 and the second clamping plate 344 on the corresponding feeding tracks 342 respectively, and then opens the feeding port 341 so that the two groups of products can be sucked out from the port. After that, the suction cup structure 350 reverses the product through the rotating shaft 351, then disconnects the suction cup, so that the suction cup falls on the pushing track of the pushing structure 360, and then the product is pushed into the fixed gripper 430 staying at the outlet by the cylinder.

[0049] The adjusting screw 434 of the fixed gripper adjusts the gap between the limit rod 435 and the gripper bracket 431 according to the thickness of the product, so as to cooperate with the fixing part 432 to complete the clamping and fixing after the product is pushed into the gap. Subsequently, the fixed gripper 430 is driven by the annular module 410 to operate in a circular motion through the drive chain 420. During this process, the transmission connecting rod 436 also moves on the annular guide rail 440. The barrel 450 pumps out the spraying material through the feeding pump 481 and conveys it to the spraying trough 482 through a pipeline. The front end of the spraying trough 482 is provided with spraying holes 483. After being pumped out, the spraying material is sprayed out through the spraying holes 483, forming a downward waterfall structure on the buffer flat plate 484. The spraying material flows vertically downward like a waterfall and then is poured on the product to complete the coating.

[0050] Subsequently, the product is fixed by the fixed gripper 430 and moves in a circle on the annular module 410. During this process, it moves on the upper track 441. When it reaches the lower track 442, the height difference between the upper and lower slopes causes the transmission connecting rod 436 to be fixed in the track, and due to gravity, it rotates, causing the fixed gripper 430 to flip. Then the product on the fixed gripper 430 also completes a 180° flip, and then the excess coating can be poured out by flipping. The excess coating will flow into the material distribution trough 460, and the air knife machine 470 will scrape off the excess coating.

[0051] After the coating is completed, the product is transferred to the conveyor belt 620 through the transfer manipulator 500, and then sent into the oven 610 through the conveyor belt 620 to complete drying, and finally discharged.

[0052] Compared with the traditional technology, the present invention greatly improves the efficiency of feeding the product into the spraying station by reforming the material distribution station; realizes high-speed spraying by improving the spraying structure; at the same time, quickly drains the solution by automatic flipping.

[0053] The specific embodiments of the present invention have been described above, but the present invention is not limited thereto. As long as it does not deviate from the purpose of the present invention, the present invention can have various changes.
