Technical Field

[0001] The present invention relates to the technical field of flipping mechanisms, and specifically to a double-sided flipping mechanism. Background Art

[0002] Metallurgical silicon, also known as metal silicon, is produced by drying and smelting silicon mud. Specifically, wet silicon mud is placed in a special oven for drying and then transferred to an intermediate frequency furnace for smelting and impurity removal. Silicon mud is a low-temperature antioxidant, commonly soft, with a delicate feel, light weight, porous structure, and strong water absorption. After drying, the exposed silicon is extremely prone to generating dust in the air, and the metallurgical silicon obtained by smelting in an intermediate frequency furnace has the characteristics of being hard and brittle. Given the different characteristics of silicon materials at different stages of the metallurgical silicon production process, there are still many problems to be solved in processes such as drying, transportation, smelting, and crushing.

[0003] In the stage of silicon material unloading, it is necessary to unload and bag the dried silicon material. The prior art "CN 110182587 A" discloses "a low-temperature antioxidant material conveying integrated device". The tray containing the dried material slides above the flipping and unloading section through the feeding platform, cross roller table, and conveying section. The ejector rod of the cylinder extends to press down the four corners of the tray, and then the flipping guide rail is driven to flip by the flipping motor, and the material is poured into the receiving hopper. The flipping mechanism flips and resets the tray containing the material once, and then flips and resets the next tray. For the same tray, the rotation mechanism needs to rotate 360° to complete one unloading, resulting in low unloading efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a double-sided flipping mechanism to solve the problem of low unloading efficiency mentioned above.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A double-sided flipping mechanism includes a housing, a bracket, a flipping motor, a rotating shaft, a coupling, and a rotating base plate.

A hole adapted to the rotating shaft is opened in the center of the side plate, and the rotating shaft passes through the hole. One end of the rotating shaft is connected to a coupling, and the other end of the coupling is connected to the flipping motor. Mounting strips are fixedly connected to both sides of the rotating base plate, and the mounting strips are welded to the rotating shaft.

[0006] Preferably, support frames extending forward and backward are fixedly connected to the bottom of the bracket, and a plurality of cylinders for supporting the tray are fixedly connected to the support frames, and the cylinders correspond to the four corners of the tray.

[0007] Preferably, the piston rods of the cylinders are vertically upward, and buffer sponges are wrapped around the tops of the cylinders.

[0008] Preferably, conveying roller paths with transport trays are provided at both ends of the support frame, and a limiting device is provided on the roller paths to limit the position of the trays.

[0013] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0014] Please refer toFigures 1-9 In the embodiment of the present invention, a double-sided flipping mechanism includes a housing 1, a bracket 2, a flipping motor 3, a rotating shaft 4, a coupling 5, and a rotating bottom plate 7. A bracket 2 is arranged inside the housing 1. Side plates 21 are arranged at both ends of the bracket 2. A hole adapted to the rotating shaft 4 is opened in the center of the side plate 21. The rotating shaft 4 passes through the hole. One end of the rotating shaft 4 is connected to a coupling 5, and the other end of the coupling 5 is connected to the flipping motor 3. Installation strips 71 are fixedly connected to both sides of the rotating bottom plate 7, and the installation strips 71 are welded to the rotating shaft 4. The rotating bottom plate 7 is driven by the installation strips 71 welded to the rotating shaft 4 and can rotate following the motor.

[0015] Furthermore, support frames 22 extending out are fixedly connected to the front and rear of the bottom of the bracket 2. A plurality of cylinders 8 for supporting the tray 6 are fixedly connected to the support frames 22. The cylinders 8 correspond to the four corners of the tray 6. A limiting device is arranged on the conveying roller path 9, which can ensure that the position of the tray 6 reaching the rotating bottom plate 7 is fixed.

[0016] Furthermore, the piston rods of the cylinders 8 are vertically upward, and buffer sponges are wrapped around the tops of the cylinders 8. Wrapping buffer sponges around the tops of the cylinders 8 can play a role in shock absorption during the telescopic process of the cylinders 8 and extend the service life.

[0017] Furthermore, referring to Figure 6 , an electromagnet 72 for adsorbing the tray 6 is embedded in the middle of the rotating bottom plate 7, and a wire routing duct 73 is reserved inside the rotating bottom plate 7. The electromagnet 72 can control magnetism by controlling power on and off, and can avoid the tray 6 from falling off during the unloading process. Referring to Figure 7 , the width of the rotating bottom plate 7 is narrower than the width of the tray 6 because a part of the tray 6 needs to contact the conveying roller path 9 and is conveyed by the conveying roller path 9.

[0018] Furthermore, referring to Figure 8 、 Figure 9 , conveying roller paths 9 for transporting the tray 6 are arranged at both ends of the support frame 22. The conveying roller paths 9 play a role in connecting each process in the production process, ensuring the continuity and stability of the production line. A channel is opened in the housing 1 at the position where the conveying roller path 9 passes, and flexible PVC strip doors are arranged at the entrances and exits of the channel.

[0019] The working principle of the present invention is: Taking the perspective of looking down at the equipment as the standard, the position of the conveying roller path 9 is distinguished. The conveying roller path 9 located above is the upper conveying roller path 9, and the conveying roller path 9 located below is the lower conveying roller path 9. Referring to Figure 3 , it is set that the upper plate surface of the rotating bottom plate 7 at this time is the A surface, and the lower plate surface is the B surface. The A surface faces upward and the B surface faces downward. At this time, the silicon material in the tray 6 on the B surface has been unloaded, and the A surface is the tray 6 filled with silicon material transported by the conveying roller path 9.

[0020] The tray 6 loaded with silicon material is transferred from the previous process to the unloading section here. The A-side tray 6 to be unloaded is adsorbed by the electromagnet 72 on the rotating bottom plate 7, and the silicon material in the tray 6 is not magnetic, so it will not be adsorbed to cause material residue. The shell 1 arranged outside the double-sided reversal mechanism can prevent the silicon material from flying out of the station and being lost during the rotation process. The conveying roller 9 can convey the tray 6 to the specified position. There is a rotating roller on the front side of the conveying roller 9, which can transport the tray 6 from the roller to the rotating bottom plate 7. The conveying roller 9 is provided with a limiting device to ensure that the tray 6 can be transported to the specified position one by one. The limiting device is relatively conventional and will not be described in detail here. refer to Figure 1 , the conveyor roller 9 rotates the tray 6 containing silicon materials to the bottom plate 7. At this time, the electromagnet 72 is energized, and the A surface of the rotating bottom plate 7 adsorbs the tray 6 containing silicon materials. The flip motor 3 is started, and the rotating bottom plate 7 rotates 180° through the rotating shaft 4. The silicon materials in the tray 6 containing silicon materials are dumped out by gravity, and the unloading work is completed. The cylinder 8 fixed on the upper side of the support frame 22 extends and supports the four corners of the tray 6 to prevent the tray 6 from falling off during the unloading process. Figure 2 After the flipping and unloading is completed, the rotating bottom plate 7 and the trays 6 on the A and B sides that are sucked are transferred to the upper conveying roller 9, and at this time, the B side of the rotating bottom plate 7 faces upward and the A side faces downward. The conveying roller 9 conveys the tray 6 on the B side of the rotating bottom plate 7 that is already free of silicon material to the next process, and then the conveying roller 9 conveys the next tray 6 full of silicon material waiting in line on the conveying roller 9 to the B side of the rotating bottom plate 7 of the flipping mechanism; After the above actions are completed, the electromagnet 72 is energized, and the rotating bottom plate 7 absorbs the empty tray 6 on the A side of the column that has been unloaded and the tray 6 full of silicon materials conveyed by the upper conveyor roller 9 on the B side, and the flip motor 3 is started, the rotating shaft 4 is driven, and the rotating bottom plate 7 rotates -180° and flips from the upper conveyor roller 9 to the lower conveyor roller 9. Figure 3 At this time, the B side of the rotating bottom plate 7 returns to the downward position, the A side faces upward, and the silicon material in the tray 6 on the B side is unloaded, and the cylinder 8 fixed on the lower support frame 22 also performs the specified action synchronously. The empty tray 6 on the A side of the rotating bottom plate 7 is transported to the next process via the lower conveyor roller 9, and at the same time, the lower conveyor roller 9 transports the next tray 6 full of silicon material to the A side of the rotating bottom plate 7 and fixes it to perform the next action. In this way, the empty tray 6 is transported and the tray 6 full of silicon material is turned over and unloaded.

[0021] refer to Figure 4 The silicon material unloaded from the tray is collected by the bottom hopper, transported to a high place by a conveyor belt, packed into bags, and sent to the smelting workshop for smelting.

[0022] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent substitutions or changes should be covered by the protection scope of the present invention.
