Description

Technical Field

[0001] The present invention relates to the technical field of turnover mechanisms, in particular to a double-sided turnover mechanism. Background Art

[0002] Industrial silicon, also known as metallic silicon, is produced by drying and smelting silicon mud. Specifically, wet silicon mud is dried in a special oven and then transferred to an intermediate frequency furnace for smelting and impurity removal. Silica mud is a low-temperature antioxidant, typically soft, delicate, lightweight, porous, and highly absorbent. Dried silicon easily generates dust when exposed to air, while industrial silicon smelted in an intermediate frequency furnace is hard and brittle. Given the varying properties of silicon materials at different stages of the industrial silicon production process, many challenges remain to be addressed in the drying, transportation, smelting, and crushing processes.

[0003] During the silicon material unloading stage, the dried silicon material needs to be unloaded and bagged. 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 unloading section via a loading platform, a cross roller, and a conveying section. The cylinder's ejector rod extends out of the four corners of the tray, and then the flip motor drives the flip guide rail to flip, and then dump the material into the receiving hopper. The flip mechanism flips the tray containing the material once and then resets it, and then flips the next tray and resets it. For the same tray, the unloading rotation mechanism rotates 360 degrees to complete one unloading, resulting in low unloading efficiency. Summary of the Invention

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

[0005] To achieve the above object, the present invention provides the following technical solutions:

The bracket is arranged inside the shell, and side plates are arranged at both ends of the bracket. A hole is opened in the center of the side plate to match the rotating shaft. The rotating shaft passes through the hole. One end of the rotating shaft is connected to the 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.

[0007] Preferably, the bottom of the bracket is fixedly connected to a protruding support frame at the front and rear ends, and a plurality of cylinders for supporting the tray are fixedly connected to the support frame, and the cylinders are located corresponding to the four corners of the tray.

[0008] Preferably, the cylinder piston rod is vertically upward, and the top of the cylinder is wrapped with a buffer sponge.

[0009] Preferably, conveyor rollers for transporting pallets are provided at both ends of the support frame, and a limiting device is provided on the rollers to limit the position of the pallet.

[0010] Preferably, an electromagnet for adsorbing the tray is embedded in the middle of the rotating base plate, and a wiring conduit is reserved inside the rotating base plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 9 In an 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 base plate 7. The bracket 2 is disposed within the housing 1. Side plates 21 are disposed at both ends of the bracket 2. A hole is formed in the center of the side plates 21 to accommodate the rotating shaft 4. The rotating shaft 4 passes through the hole. One end of the rotating shaft 4 is connected to the coupling 5, and the other end of the coupling 5 is connected to the flipping motor 3. Mounting bars 71 are fixedly connected to both sides of the rotating base plate 7, and the mounting bars 71 are welded to the rotating shaft 4. The rotating base plate 7 is driven by the mounting bars 71 welded to the rotating shaft 4 and can rotate with the motor.

[0025] Furthermore, the bottom of the bracket 2 is fixedly connected to an extended support frame 22 at the front and rear, and a plurality of cylinders 8 for supporting the pallet 6 are fixedly connected to the support frame 22. The cylinders 8 correspond to the four corners of the pallet 6, and a limiting device is provided on the conveying roller 9 to ensure that the pallet 6 is fixed in position when it reaches the rotating base plate 7.

[0026] Furthermore, the piston rod of the cylinder 8 is vertically upward, and the top of the cylinder 8 is wrapped with a cushioning sponge. The cushioning sponge is wrapped on the top of the cylinder 8, which can play a shock-absorbing role during the expansion and contraction of the cylinder 8 and extend the service life.

[0027] Further, refer to Figure 6 The rotating bottom plate 7 is embedded with an electromagnet 72 for adsorbing the tray 6, and a wiring conduit 73 is reserved inside the rotating bottom plate 7. The electromagnet 72 can control the magnetism by controlling the on and off power to prevent the tray 6 from falling off during the unloading process. Figure 7 The width of the rotating base plate 7 is narrower than the width of the tray 6 because part of the tray 6 is in contact with the conveying roller 9 and is conveyed by the conveying roller 9.

[0028] Further, refer to Figure 8 、 Figure 9 Conveyor rollers 9 for transporting pallets 6 are provided at both ends of the support frame 22. The conveyor rollers 9 connect the various processes in the production process, ensuring the continuity and stability of the production line. A passage is provided in the housing 1 where the conveyor rollers 9 pass, and flexible PVC strip doors are provided at the entrance and exit of the passage.

[0029] The working principle of the present invention is:

[0030] Based on the angle of looking down at the equipment, the position of the conveyor roller 9 is distinguished. The one located above is the upper conveyor roller 9, and the one located below is the lower conveyor roller 9. Figure 3 At this time, the upper surface of the rotating bottom plate 7 is set as surface A, and the lower surface is set as surface B, with surface A facing up and surface B facing down. At this time, the silicon material in the tray 6 on surface B has been unloaded, and surface A is the tray 6 full of silicon material conveyed by the conveyor roller 9.

[0031] 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 attracted by the electromagnet 72 on the rotating base plate 7. The silicon material in the tray 6 is not magnetic and therefore will not be attracted, resulting in residual material. The shell 1 arranged outside the double-sided reversal mechanism can prevent the silicon material from flying out of the work station and being lost during the rotation process. The conveyor roller 9 can convey the tray 6 to the designated position. There is a rotating roller on the front side of the conveyor roller 9, which can transport the tray 6 from the roller to the rotating base plate 7. The conveyor roller 9 is provided with a limiting device to ensure that the tray 6 can be transported to the designated position one by one. The limiting device is relatively conventional and will not be described in detail here.

[0032] refer to Figure 1 The conveyor roller 9 rotates the tray 6 containing silicon material onto the rotating base plate 7. At this time, the electromagnet 72 is energized, and the A surface of the rotating base plate 7 attracts the tray 6 containing silicon material. The flip motor 3 is started, and the rotating base plate 7 rotates 180 degrees through the rotating shaft 4. The silicon material in the tray 6 containing silicon material is dumped out under the action of gravity, completing the unloading work. 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 base plate 7 and the trays 6 on the A and B sides that were sucked are transferred to the upper conveyor roller 9, with the B side of the rotating base plate 7 facing up and the A side facing down. The conveyor roller 9 transports the tray 6 on the B side of the rotating base plate 7, which is already empty of silicon material, to the next process step. Then, the conveyor roller 9 transports the next tray 6 full of silicon material waiting in line on the conveyor roller 9 to the B side of the rotating base plate 7 of this flipping mechanism.

[0033] After completing the above actions, the electromagnet 72 is energized, and the rotating bottom plate 7 absorbs the empty tray 6 that has been unloaded on the A side of the column and the tray 6 filled with silicon material that has been conveyed from the upper conveyor roller 9 on the B side. The flip motor 3 is started, and the rotating shaft 4 is driven, and the rotating bottom plate 7 rotates -180 degrees and flips from the upper conveyor roller 9 to the lower conveyor roller 9. Figure 3At this point, side B of the rotating base plate 7 returns to its downward position, side A faces upward, and the silicon material in the tray 6 on side B is unloaded. The cylinder 8, fixed to the lower support frame 22, also performs its prescribed action simultaneously. The empty tray 6 on side A of the rotating base plate 7 is transported to the next process step via the lower conveyor roller 9. Simultaneously, the lower conveyor roller 9 transports the next tray 6 filled with silicon material to the A side of the rotating base plate 7, where it is fixed for the next step. This reciprocating process of transporting empty trays 6 and flipping and unloading trays 6 filled with silicon material is repeated.

[0034] 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, bagged, and sent to the smelting workshop for smelting.

[0035] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
