Description

Technical Field

[0001] The invention relates to the technical field of plate transportation in a coating line, and in particular to a conveying device for a plate coating line. Background Art

[0002] The plate coating production line is an automated production line used for coating plates. The production line is usually composed of multiple parts, including pre-treatment equipment, powder spraying system, paint spraying equipment, oven, heat source system, electronic control system and hanging conveyor chain, etc. In these processing processes, conveying equipment is required to continuously transport the plate materials, so a conveying equipment for the plate coating line is needed.

[0003] The following problems are likely to occur during the conveying of plates: The initial process usually requires manual loading. When multiple plates need to be loaded manually at the same time, it is difficult to ensure that the positions of the plates are completely aligned. When there is a tilt or deviation between the positions, the materials are prone to blockage or accumulation during the transportation process. During the loading process of a large number of plates, it is easy for them to have different sizes. Transporting plates of different sizes will lead to instability during the transportation process, and the plates are easily damaged. The thickness and size differences between some plates are small, making it difficult to quickly identify them during the loading process. At different process stages of the coating production line, the plate may need to temporarily stop and wait. If the material is continuously loaded, it will cause chaos in production. If the corresponding device is stopped, the plate is prone to tilt and offset due to inertia, and some processing is not completed, which is easy to cause incomplete processing and reduce processing accuracy. During the long-term transportation process, the long-term contact between the plate and the conveying device can easily wear the equipment and affect the accuracy and operation. It can also easily cause equipment failure or affect the coating quality, thereby reducing the service life of the equipment. Summary of the invention

There are multiple conveying shafts 28, and the conveying shafts 28 are connected by transmission belts. Gear 27 is welded on both ends of one of the conveying shafts 28. The mutual meshing between gear 27 and gear 1 22 can ensure the continuous rotation of the conveying shaft 28. Guide rollers are installed on the bottom side of the conveying shaft 28, and the guide rollers are also connected between the inner walls of the recovery rack. The positions of the rack plate and the guide rollers correspond to each other to facilitate the removal of plates that do not meet the thickness. Outer baffles 37 are symmetrically installed on both sides of the circulation rack 3, and a partition rack is fixed on the top surface of the circulation rack 3. The feeding roller 38 is connected between the circulation rack 3 and the partition rack, and the return roller 33 is connected between the circulation rack 3 and the outer baffle 37. , two groups of electric translation wheels 31 are symmetrically arranged, and the directions of the two groups of electric translation wheels 31 are opposite, a plurality of sprocket wheels are arranged between the inner walls of the partition frame, one end of the feed roller 38 is fixed on the sprocket wheel, the outer side of the sprocket wheel is connected to the conveying chain 35, which can drive a plurality of feed rollers 38 to rotate at the same time, and a motor 2 36 is also installed at one end of the partition frame to control the movement of the conveying chain 35, a bevel gear group 39 is connected between the return roller 33 and the feed roller 38, and the bevel gear group 39 is three bevel gears of vertical transmission, and the return roller 33 and the feed roller 38 are respectively connected to two parallel bevel gears to act on the synchronous reverse movement of the two, and the baffle frame 32 is installed on the circulation On the discharge end side of the rack 3, the baffle rack 32 includes a baffle bar, a connecting rod, a bottom shell and a supporting magnetic rod 322. The connecting rod is rotatably connected between the inner walls of the circulation rack 3. A plurality of baffle bars are arranged and installed on the connecting rod to block the plate.

[0021] Working principle: stack the plates and place them in the device frame 1, rotate the extrusion rotating rod 111, the conical pressure block 113 will continuously squeeze the outer push plate 112 outward, so that the plates can be directly aligned and transported out from the discharge port smoothly. During the transportation, the detection block 19 will measure the thickness of each plate. At this time, the push plate motor is controlled to rotate at a uniform speed, which will drive the push plate belt 12 to rotate. Under the movement of the push plate belt 12, the push block 13 will move to the guide frame 17 and push the plate on the bottom side out of the device frame 1. The pushed plate will move directly to the conveyor belt 21 through the frame plate. Driven by motor 1 26, the plate will be transported to the circulation frame 3. At the same time, start motor 2 36. Driven by the conveyor chain 35, the feeding roller 38 will transport the material forward at a uniform speed until it moves out of the circulation frame 3 and enters the next process. When the roller 38 moves, the return roller 33 will reverse at the same time. When the next process needs to stop and wait, the electromagnetic block 321 will lose power and the supporting magnetic rod 322 will pop up under the action of the spring, and the baffle frame 32 will move upward, thereby blocking the material at the discharge end of the circulation frame 3. After blocking, the cylinder baffle 34 will extend to block the subsequent plates. At the same time, the electric translation wheel 31 will start to translate the material on the feeding roller 38 to both sides, and then the plate is returned through the return roller 33 and the electric translation wheel 31 on the other side, forming a circular movement effect. The material on the rear side can control the equipment to stop loading. When transportation needs to be resumed, the baffle frame 32 will be reset. After the first piece of material is transported out, the cylinder baffle 34 will retract. When all the plates are moved to the feeding roller 38, the electric translation wheel 31 also stops rotating.

[0023] Working principle: When the plate is loaded, if the detection block 19 measures that the thickness of the material does not meet the standard, the external instrument of the equipment will have a prompt, and then turn the fixing screw 166.

[0025] Working principle: With the continuous rotation of the conveyor belt 21, the cleaning brush roller 29 will be driven to continuously clean and wipe the conveyor belt 21. After a long period of wiping, the positioning screws can be loosened to clean it. If the wiping force is insufficient, the distance between the cleaning brush roller 29 and the conveyor belt 21 can be adjusted to improve the cleaning effect by changing the pressure. When the feed roller 38 is to be cleaned, the control motor three 43 is rotated, and the take-up roller 42 will reel in the pull rope 44. Driven by the pull rope 44, the lower rack 45 will move to one side. Under the connection of the transmission gear, the upper gear will slide to the other side along the limit slide bar 47. During the sliding process, the wiping frame 48 will wipe the feed roller 38. When the lower rack 45 moves, the return spring 46 will be stretched. After the one-way wiping is completed, the control motor three 43 starts to reverse. Under the rebound of the return spring 46, the lower rack 45 will return to its original position, indirectly restoring the wiping frame 48. Repeated operations can achieve the effect of cyclic wiping.
