[0029] like Figures 1 to 5 The figure shows a low-cost blanking device provided by the present invention. In this embodiment, it includes two first-level paddle rotating mechanisms 3, two second-level paddle rotating mechanisms 4, a middle partition 2, and a blanking outer frame 1 made of sheet metal. The blanking outer frame 1 is composed of two side sheet metal panels, a back sheet metal panel, and a middle front cover sheet metal panel. The upper end of the blanking outer frame is the feed port, and the lower end is the discharge port. Compared with aluminum frames, the manufacturing cost is greatly reduced.

[0030] like Figure 3 As shown, the middle partition plate 2 is arranged at intervals in the blanking outer frame 1 to divide the blanking outer frame 1 into two blanking channels 5 with equal spaces, and the first-level paddle rotating mechanism 3 and the second-level paddle rotating mechanism 4 are respectively located in the upper and lower parts of each blanking channel 5; the blanking channel 5 is provided with a debris discharge port 6 between the first-level paddle rotating mechanism 3 and the second-level paddle rotating mechanism 4, that is, the blanking channel 5 is arranged from top to bottom as the first-level paddle rotating mechanism 3, the debris discharge port 6 and the second-level paddle rotating mechanism 4. When the material of the previous process is determined to be unqualified material after detection, the first-level paddle rotating mechanism 3 will rotate the paddle 343 to allow the material to be introduced into the debris discharge port 6. When the material of the previous process is determined to be qualified material after detection, the first-level paddle rotating mechanism 3 will rotate the paddle 343 to allow the material to be introduced into the paddle 343 of the second-level paddle rotating mechanism 4. Finally, the second-level paddle rotating mechanism 4 rotates the paddle 343 to allow the qualified material to be introduced into the storage hopper.

[0031] Specifically, the first-level paddle rotating mechanism 3 and the second-level paddle rotating mechanism 4 both include a driving mechanism 341, a driving shaft 342 and a paddle 343. The driving mechanism 341 and the driving shaft 342 are driven and connected, and the end of the paddle 343 close to the outside of the blanking outer frame 1 is connected to the driving shaft 342 through a fastener 344; in the second-level paddle rotating mechanism 4 of this embodiment, the paddle 343 is a single-leaf paddle, and rotates left and right around the driving shaft 342; in the first-level paddle rotating mechanism 3 of this embodiment, the paddle 343 is a three-leaf paddle, and rotates left and right around the driving shaft 342, and each lower The width of the material channel 5 matches the diameter of the three-leaf paddle, and the debris discharge opening 6 is located below the three-leaf paddle. The width of the debris discharge opening 6 matches the radius of the three-leaf paddle, that is, each row of debris discharge openings 6 only occupies half the width of each material discharge channel 5; and the debris discharge openings 6 of the two material discharge channels 5 are both arranged close to the middle partition 2, that is, relative to the material discharge outer frame 1, the two rows of debris discharge openings 6 are centered; the inner side of the material discharge outer frame 1 is matched with an extended rejection channel 7 at the end of the two rows of debris discharge openings 6, that is, the width of the rejection channel 7 is half of the material discharge outer frame 1, which saves and optimizes space while meeting the material discharge requirements;

[0032] During specific operation, when the material of the previous process is determined to be unqualified material after detection, the signal is transmitted to the first-level paddle rotating mechanism 3, and the driving mechanism 341 drives the driving shaft 342 to rotate, driving the three-leaf paddle to rotate toward the impurity discharge port 6. At this time, the three-leaf paddle and the impurity discharge port 6 form an impurity discharge channel, and the material enters the rejection channel 7 along the impurity discharge channel to complete impurity discharge; when the material of the previous process is determined to be qualified material after detection, the three-leaf paddle rotates to the other side of the impurity discharge port 6, and the three-leaf paddle and the other side of the impurity discharge port 6 form a material transfer channel, and the material falls along the material transfer channel to the one-leaf paddle of the second-level paddle rotating mechanism 4. At the same time, after the second-level paddle rotating mechanism 4 receives the signal, the driving mechanism 341 drives the driving shaft 342 to rotate, driving the one-leaf paddle to rotate and pour the material into the storage hopper of the line body to complete the discharge;

[0033] In addition, if Figures 1 to 3 As shown, an upper transparent front cover plate 11 and a lower transparent front cover plate 12 are respectively provided on the outer side of the blanking outer frame 1 at the first-level paddle rotating mechanism 3 and the second-level paddle rotating mechanism 4, and the blanking outer frame 1 is detachably connected to the upper transparent front cover plate 11 and the lower transparent front cover plate 12 respectively. When the paddle 343 needs to be replaced, the upper transparent front cover plate 11 or the lower transparent front cover plate 12 is removed from the outer side of the blanking outer frame 1, and the paddle 343 and the fastener 344 connected to the drive shaft 342 are loosened, and the paddle 343 can be taken out, which is very convenient, reduces the disassembly time, and reduces the maintenance cost.

[0034] Further, if Figures 1 to 3As shown, the blanking outer frame 1 is detachably connected to the upper transparent front cover 11 through an upper connecting member 13. In this embodiment, the upper connecting member 13 is L-shaped, and one side of the upper connecting member 13 is connected to the side wall of the blanking outer frame 1 by screws, and the other side of the upper connecting member 13 is connected to the upper transparent front cover 11 by screws. The screw connection is convenient for disassembly.

[0035] Further, if Figures 1 to 3 As shown, the lower halves of the left and right side walls of the blanking outer frame 1 are provided with side guide plates 14. The outer sides of the side guide plates 14 are detachably connected to the lower transparent front cover plate 12 through a lower connecting member 15. The lower connecting member 15 can be a straight plate or an L-shaped plate. In this embodiment, the lower connecting member 15 is a straight plate and is welded to the outer side of the side guide plate 14. The lower transparent front cover plate 12 is connected to the lower connecting member 15 by screws. The screw connection is convenient for disassembly.

[0036] Further, if Figure 3 As shown, the upper halves of the left and right side walls of the blanking outer frame 1 and the upper half of the middle partition 2 are each provided with an inclined surface 121. The inclined surface 121 matches the rotation path of the paddle 343 in the first-stage paddle rotating mechanism 3. When cleaning, two adjacent leaves of the three-leaf paddle of the first-stage paddle rotating mechanism 3 form a sealed impurity discharge channel with the inclined surface 121 of the middle partition 2 and the side wall of the impurity discharge port 6, respectively, to ensure that unqualified materials enter the impurity discharge channel. When qualified materials enter, two adjacent leaves of the three-leaf paddle of the first-stage paddle rotating mechanism 3 form a sealed material transfer channel with the upper halves of the side walls of the blanking outer frame 1 and the side walls of the impurity discharge port 6, respectively, to ensure that qualified materials enter the second-stage paddle rotating mechanism 4.

[0037] Further, if Figure 3 As shown, the lower half of the middle partition 2 is provided with a middle guide plate 21, and the side guide plates 14 and the middle guide plates 21 are matched with the rotation path of the paddle 343 of the secondary paddle rotating mechanism 4. When qualified materials enter the secondary paddle rotating mechanism 4, under the drive of the driving mechanism 341, one leaf paddle of the secondary paddle rotating mechanism 4 rotates to a vertical state, so that the material falls downward along the one leaf paddle into the storage hopper; in addition, the side guide plates 14 and the middle guide plates 21 both have a guiding function, so that the qualified materials are smoothly introduced onto the one leaf paddle and smoothly fall into the storage hopper through the discharge port.

[0038] Furthermore, the two rejection channels 7 are of integrated design, that is, the two rejection channels 7 share a partition plate, which saves manufacturing costs.

[0039] Furthermore, a frame-type photoelectric 16 for sensing material speed is provided at the feed port of the unloading outer frame 1. The frame-type photoelectric 16 can detect the speed at which the material enters the feed port. In the early debugging stage, the frame-type photoelectric 16 continuously detects the speed at which multiple materials enter the feed port, thereby obtaining a standard speed range. If in the later operation stage, the frame-type photoelectric 16 detects that the speed at which the material enters the feed port does not meet the standard speed range, it will convey the signal to the first-level paddle rotating mechanism 3, and the first-level paddle rotating mechanism 3 will remove impurities. If the frame-type photoelectric 16 detects that the speed at which the material enters the feed port is within the standard speed range, the first-level paddle rotating mechanism 3 will guide the material into the second-level paddle rotating mechanism 4, and the second-level paddle rotating mechanism 4 will lower the material into the storage hopper.

[0040] To sum up, in the present invention, the middle partition 2 is arranged at intervals in the blanking outer frame 1 to divide the blanking outer frame 1 into two blanking channels 5, and the first-level paddle rotating mechanism 3 and the second-level paddle rotating mechanism 4 are respectively located in the upper and lower parts of the blanking channel 5, and the middle part of the blanking channel 5 is provided with a debris discharge port 6 that matches the radius of the paddle 343 of the first-level paddle rotating mechanism 3, and the two rows of debris ports 6 are arranged close to the middle partition 2; the ends of the two rows of debris ports 6 are matched with extended rejection channels 7, that is, the setting of the rejection channel 7 saves and optimizes space while meeting the requirements of material discharge, and the blanking outer frame 1 is made of sheet metal, which greatly reduces the production cost; in addition, the outer side of the blanking outer frame 1 is detachably connected to the upper transparent front cover 11 and the lower transparent front cover 12 at the first-level paddle rotating mechanism 3 and the second-level paddle rotating mechanism 4, that is, the paddle 343 can be replaced by removing the upper transparent front cover 11 or the lower transparent front cover 12, thereby reducing maintenance costs.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
