Description

Technical Field

[0001] The present application relates to the technical field of low-pressure casting, and in particular to a low-pressure casting mold for forming a flywheel. Background Art

[0002] A flywheel is a disc-shaped part with a large moment of inertia, usually arranged at the rear end of the rotating shaft of the machine. When producing a flywheel, low-pressure casting is usually adopted. It is a method of filling the mold cavity with liquid metal under pressure to form a casting. Since the pressure used is relatively low, it is called low-pressure casting.

[0003] During use of the existing low-pressure casting equipment for flywheel casting, after the flywheel is formed, it is in a state of being embedded in the mold cavity. It is troublesome for the staff to take it out, which affects the subsequent casting work. In addition, in some cases, multiple flywheels are cast continuously and the cast flywheels are uniformly transported. The formed flywheels may be placed in a relatively messy state around the equipment, which is not convenient for subsequent transportation. In addition, usually, after the flywheel is formed, the staff is required to check the casting quality of the flywheel. By observing the appearance of the flywheel, the surface defects of the flywheel can be discovered and dealt with in time to ensure that the product quality meets the requirements. The messily placed flywheels are not conducive to the staff to check their appearance quality, and confusion may occur. In addition, when the appearance quality of a flywheel is checked every time it is formed, the whole process is relatively cumbersome, which affects the inspection efficiency.

[0004] In response to the above technical problems, the patent number CN211101532U discloses a low-pressure casting equipment for flywheel casting, including a base, an insulation furnace and a workbench, a crucible is fixed in the insulation furnace, a furnace cover is sealed on the top of the insulation furnace, a liquid riser that penetrates into the crucible is fixed at the center of the furnace cover, a lower mold is arranged at the middle position of the upper surface of the workbench, a cavity connected to the top of the liquid riser is arranged in the lower mold, a protective cover fixed on the outer cover of the lower mold is arranged, the output end of the cylinder is connected to a lower pressure plate through a piston rod, an upper mold symmetrical to the lower mold is arranged at the bottom of the lower pressure plate, and a cooling fan is installed on the rear wall of the protective cover. This patent can make the upper mold and the lower mold in a relatively sealed environment, reduce the inconvenience of cleaning caused by the mold being exposed to the air for a long time and attached to dust, and can cool the mold to accelerate the solidification and molding speed of the casting.

[0005] However, the above technical solution has the following defects:

[0006] (1) After the flywheel is formed, it is embedded in the mold cavity. It is troublesome for the staff to take it out, which affects the subsequent casting work. In some cases, multiple flywheels are cast continuously and the cast flywheels are transported uniformly. The formed flywheel may be placed around the equipment in a messy state, which is not convenient for subsequent transportation. In addition, usually, after the flywheel is formed, the staff needs to check the casting quality of the flywheel. By observing the appearance of the flywheel, the surface defects of the flywheel can be discovered and dealt with in time to ensure that the product quality meets the requirements. The messy placement of the flywheel is not conducive to the staff to check its appearance quality, which may cause confusion. In addition, when the appearance quality of each flywheel is checked after it is formed, the whole process is cumbersome, which affects the inspection efficiency. Summary of the invention

[0019] Compared with the prior art, the beneficial effects of this application are:

[0020] (1) When the molten metal in the molding cavity is cooled and solidified, the mold 2 is driven to rise. At this time, the extension and retraction of the electric push rod 2 can be used to drive the connecting plate to move horizontally, so that the demolding rod moves to the left to eject the molded flywheel, thereby eliminating the need to manually remove the molded flywheel from the molding cavity, which is more convenient.

[0021] (2) By utilizing the tooth overlap separation placement mechanism, the molded flywheel ejected by the demoulding rod can be sleeved on the positioning rod, and the adjacent flywheels fit together, thereby realizing the unified arrangement and placement of multiple molded flywheels, which is relatively neat and convenient for the subsequent unified transportation of the flywheels. At the same time, the neatly arranged flywheels are also easy for the staff to check their appearance quality, and defective flywheels can be discovered and handled in time. Moreover, compared with the method of conducting a quality inspection on each flywheel after it is molded, this unified inspection is easy to observe and compare, thereby improving the inspection efficiency. Moreover, whenever a flywheel slides onto the positioning rod, the extrusion rod is driven to slide from left to right on the slide rod 3, and the spacer is squeezed, so that the end of the spacer is close to the flywheel until it is aligned with the flywheel. The surface of one side of the flywheel fits together. As the number of flywheels on the positioning rod increases, the extrusion rod also squeezes more spacers, so that multiple flywheels can be separated by spacers, and the flywheels will not fit each other. When a sufficient number of flywheels are mounted on the positioning rod, the positioning rod is kept horizontal, and then the extrusion rod is driven to reset to the left again to move the spacer away from the flywheel. At this time, the appearance quality of multiple flywheels can be inspected again, which can avoid the situation of blind spots in inspection caused by mutual covering between flywheels, thereby improving the comprehensiveness of appearance quality inspection. In addition, after the flywheel is mounted on the positioning rod, the embedding rod is driven to descend and contact with the flywheel. When the embedding rod contacts the flywheel, it squeezes the teeth of the flywheel until it is embedded in The grooves between adjacent teeth, when the embedded rod is embedded into the grooves between adjacent teeth of each flywheel, the teeth of multiple flywheels are aligned, so that it is convenient for inspectors to find a unified reference standard, which is not easy to cause visual fatigue and improves the accuracy of inspection. Moreover, when the teeth of multiple flywheels are aligned, the embedded rod is driven to extend from the groove of the flywheel, and then the multiple adjustment blocks are driven to move radially at the same time until all the positioning rods are in contact with the inner ring of the flywheel, so that the flywheel is positioned. At this time, the concave plate is driven to rotate, so that multiple flywheels can rotate at the same time, and the teeth at various positions of the flywheel are turned towards the inspector, which makes it easier for the inspector to observe all the teeth without moving the line of sight significantly, which is more convenient and Moreover, when it is necessary to remove the flywheel on the positioning rod, the mounting plate is driven to rotate ninety degrees clockwise, and then the threaded block and the slider are driven to slide up and down at the same time according to the number of flywheels that need to be removed at one time, and then the partition is inserted into the gap between adjacent flywheels. At this time, the positioning rod is driven away from the flywheel, and the flywheel loses its positioning and will fall downward. The flywheel below the partition will fall into the collection container, while the flywheel above the partition will be intercepted by the partition, thereby realizing the staged falling of the flywheel, and the falling amount of the flywheel at one time can be controlled according to actual needs, thereby avoiding the situation where all flywheels fall into the collection container at one time, causing difficulty for the staff to transport due to the heavy weight of the collection container, thereby improving the transportation efficiency.

[0039] As an improvement, Figure 1-Figure 12 As shown, the preferred embodiments of the present application are:

[0040] A low-pressure casting mold for forming a flywheel, comprising a workbench 1, characterized in that a mold 3 is fixedly connected to the right side of the upper end surface of the workbench 1, a mold 2 4 is slidably connected to the left end surface of the mold 3, both sides of the mold 3 are plugged and slidably connected with demoulding rods 37, and the mold 1 3, the mold 2 4, and the demoulding rod 37 cooperate with each other to form a complete molding cavity, a crucible 5 is arranged on the right side of the upper end surface of the workbench 1, and the upper end of the crucible 5 is connected to the inner cavity of the mold 3 through a connecting pipe 6, an air compressor 38 is arranged on one side of the bottom of the mold 3, and the air outlet end of the air compressor 38 is connected to one side of the crucible 5, and a tooth overlap type separation placement mechanism is also arranged on one side of the upper end surface of the workbench 1 to assist staff in checking the appearance quality of the molded flywheel;

[0041] The tooth overlap type separation placement mechanism includes a mounting frame 2 which is slidably connected to one side of the upper end surface of the workbench 1, a mounting plate 19 is rotatably provided on the upper end of the mounting frame 2, a concave plate 26 is rotatably provided on the middle part of the right end surface of the mounting plate 19, a groove plate 25 is fixedly connected to the right end of the concave plate 26, a plurality of adjustment blocks 40 are slidably connected to the groove plate 25, a positioning rod 21 is fixedly connected to the right end of the adjustment block 40, connecting rods 22 are fixedly connected to the front and rear sides of the mounting plate 19, and a plurality of spacer blocks 23 are inserted and slidably connected to the connecting rod 22.

[0042] like Figure 4 , Figure 5 , Figure 6 As shown, in this embodiment, one side of the upper end surface of the mold 1 3 is fixedly connected to an electric push rod 3 41 , and the piston end of the electric push rod 3 41 is fixedly connected to one side of the upper end of the mold 2 4 .

[0044] Specifically, when the existing low-pressure casting equipment for flywheel casting is used, after the flywheel is formed, it is in a state of being embedded in the mold cavity. It is troublesome for the staff to take it out, which affects the subsequent casting work.

[0045] Therefore, in order to solve the above problems, when the present embodiment is used, the molten metal liquid is added into the crucible 5, and then the electric push rod three 41 is used to drive the mold two 4 to descend, and at this time, the left end face of the demolding rod 37 is flush with the end face of one side of the inner cavity of the mold one 3. At this time, the mold one 3, the mold two 4, and the demolding rod 37 form a complete molding cavity, and then the air compressor 38 is used to inject compressed air into the crucible 5. After the metal liquid in the crucible 5 is subjected to pressure, it enters the molding cavity through the connecting pipe 6, and then the metal liquid in the molding cavity is cooled. The cooling means for the metal liquid is the existing technology and will not be described in detail. The metal liquid in the molding cavity is solidified and formed after cooling, and then the electric push rod three 41 is used again to drive the mold two 4 to rise. At this time, the extension and contraction of the electric push rod two 39 can be used to drive the connecting plate 31 to move horizontally, so that the demolding rod 37 moves to the left to eject the molded flywheel, thereby eliminating the process of manually removing the molded flywheel from the molding cavity, which is more convenient.

[0046] like Figure 1-Figure 3 , Figure 7-Figure 12 As shown, in this embodiment, a threaded rod 9 is threadedly connected to one side of the lower end of the mounting frame 2, and both ends of the threaded rod 9 are rotatably set on the workbench 1.

[0047] The front and rear sides of the mounting frame 2 are respectively slidably connected with a threaded block 16 and a slider 11, the left end face of the threaded block 16 is fixedly connected with an electric push rod 17, the piston end of the electric push rod 17 is fixedly connected with an adjusting plate 12, the left end face of the slider 11 is fixedly connected with a slide rod 10, the slide rod 10 is slidably connected to one end of the adjusting plate 12, one side of the threaded block 16 is threadedly connected with a threaded rod 2 15, both ends of the threaded rod 2 15 are rotatably set on the mounting frame 2, one side of the upper end of the mounting frame 2 is fixedly connected with a motor 3 14, the output end of the motor 3 14 is fixedly connected to the end of the threaded rod 2 15, and the right end face of the adjusting plate 12 is fixedly connected with a partition 13.

[0048] A turntable 34 is rotatably arranged in the middle of the left side of the groove disk 25, and a plurality of connecting rods 33 are rotatably arranged on the right end face of the turntable 34. One end of the connecting rod 33 is rotatably connected to one side of the adjustment block 40. A motor 6 32 is fixedly connected to the middle of the left end face of the groove disk 25, and the output end of the motor 6 32 is fixedly connected to the middle of the turntable 34.

[0049] A spring 24 is fixedly connected to one side of the spacer 23 , and the other end of the spring 24 is fixedly connected to the connecting rod 22 .

[0050] A slide rod 3 36 is fixedly connected to one side of the left end surface of the mounting disk 19, and the slide rod 3 36 is slidably connected to the extrusion rod 18. A threaded rod 4 35 is threadedly connected to one side of the extrusion rod 18. One end of the threaded rod 4 35 is rotatably set on the mounting disk 19. A motor 7 42 is fixedly connected to one side of the left end surface of the mounting disk 19, and the output end of the motor 7 42 is fixedly connected to one end of the threaded rod 4 35.

[0051] A motor 4 27 is fixedly connected to the middle of the left end surface of the mounting plate 19 , and an output end of the motor 4 27 is fixedly connected to the concave plate 26 .

[0052] A slide rod 2 30 is fixedly connected to one side of the left end surface of the mounting disk 19, and the slide rod 20 is slidably connected to the embedded rod 20. The left end of the embedded rod 20 is threadedly connected to a threaded rod 3 29, and the lower end of the threaded rod 3 29 is rotatably set on the mounting disk 19. A motor 5 28 is fixedly connected to one side of the left end surface of the mounting disk 19, and the output end of the motor 5 28 is fixedly connected to one end of the threaded rod 3 29.

[0053] Specifically, in the process of using the existing low-pressure casting equipment for flywheel casting, in some cases, multiple flywheels will be cast continuously, and the cast flywheels will be transferred uniformly. The formed flywheels may be placed in a relatively messy state around the equipment, which is not convenient for subsequent transfer work. In addition, usually, after the flywheel is formed, the staff is required to check the casting quality of the flywheel. By observing the appearance of the flywheel, the surface defects of the flywheel can be discovered and dealt with in time to ensure that the product quality meets the requirements. The messily placed flywheels are not conducive to the staff to check their appearance quality, and confusion may occur. In addition, when the method of checking the appearance quality of each flywheel is adopted, the whole process is relatively cumbersome, which affects the inspection efficiency.

[0054] Therefore, in order to solve the above problem, when the present embodiment is in use, when the flywheel is about to be ejected from the mold cavity by the demolding rod 37, the motor 28 is used to drive the threaded rod 19 to rotate, so that the mounting frame 2 moves to the right, and the plurality of positioning rods 21 are aligned with the inner hole of the flywheel. When the flywheel is separated from the mold 3, it will be sleeved on the positioning rod 21, and then the motor 17 drives the mounting plate 19 to rotate, so that the plurality of positioning rods 21 can be tilted, and the flywheel will slide down to the right end surface of the groove plate 25 under the action of gravity, and then the above operation is repeated, so that the plurality of formed flywheels can be sleeved on the positioning rod 21, and the adjacent flywheels can be aligned with each other. They fit each other well. When multiple flywheels need to be removed, it is only necessary to place a collection container on the positioning rod 21, and then drive the positioning rod 21 to tilt so that the flywheel can slide into the collection container through the positioning rod 21, thereby realizing the unified arrangement and placement of multiple formed flywheels, which is relatively neat and convenient for the subsequent unified transportation of the flywheels. At the same time, the neatly arranged flywheels are also easy for the staff to check their appearance quality, and defective flywheels can be discovered in time. Moreover, compared with the method of conducting quality inspection on each flywheel after it is formed, this unified inspection is easy to observe and compare, thereby improving the inspection efficiency.

[0055] Since the flywheel is fitted onto the positioning rod 21, the fitting surface of the flywheel will be covered, and it is difficult for the staff to observe the appearance quality of this position, resulting in a blind spot for inspection. In order to avoid this situation, every time a flywheel slides onto the positioning rod 21, the motor 7 42 drives the threaded rod 4 35 to rotate, so that the extrusion rod 18 slides from left to right on the slide rod 3 36. When the end of the extrusion rod 18 contacts the spacer 23, the spacer 23 is squeezed, so that the end of the spacer 23 is close to the flywheel until it fits with the surface of one side of the flywheel, and then the above operation is repeated. As the number of flywheels on the positioning rod 21 increases, the squeezing rod 18 also squeezes more spacers 23, and the spacers 23 can be used to separate multiple flywheels, so that the flywheels will not fit each other. When the number of flywheels mounted on the positioning rod 21 reaches a sufficient number, the positioning rod 21 is kept horizontal, and then the squeezing rod 18 is driven to reset to the left again, so that the spacers 23 can be moved away from the flywheels. At this time, the appearance quality of multiple flywheels can be inspected again, which can avoid the situation of blind spots in inspection due to mutual covering of flywheels, thereby improving the comprehensiveness of appearance quality inspection.

[0056] Furthermore, when the staff observes the teeth on the surface of the flywheel, since there are a large number of teeth and they are arranged around the flywheel, the staff needs to move their sight lines to a large extent to observe all the teeth, which is rather troublesome. Furthermore, the teeth of the flywheel mounted on the positioning rod 21 may be in an unaligned state. When the flywheel teeth are not aligned, the inspector's visual attention needs to be frequently switched between different flywheels and teeth in an attempt to find a unified reference standard. This frequent switching can easily cause visual fatigue, thereby affecting the accuracy of the inspection. Therefore, in order to avoid the above situation, after the flywheel is mounted on the positioning rod 21, the motor five 28 can be used to drive the threaded rod three 29 to rotate, so that the embedded rod 20 descends and contacts the flywheel. When the embedded rod 20 contacts the flywheel, it squeezes the teeth of the flywheel until it is embedded into the adjacent teeth. When the embedded rod 20 is embedded in the groove between the adjacent teeth of each flywheel, the teeth of multiple flywheels are aligned, which makes it easy for inspectors to find a unified reference standard, is not easy to cause visual fatigue, and improves the accuracy of inspection. Moreover, when the teeth of multiple flywheels are aligned, the embedded rod 20 is driven to extend from the groove of the flywheel, and then the motor six 32 is used to drive the turntable 34 to rotate, so that the multiple adjustment blocks 40 can be moved radially at the same time under the rotation of the multiple connecting rods 33, until all the positioning rods 21 are in contact with the inner ring of the flywheel, so that the flywheel is positioned. At this time, the motor four 27 is used to drive the concave plate 26 to rotate, so that the multiple flywheels can rotate at the same time, and the teeth at each position of the flywheel are turned towards the inspector, which makes it convenient for the inspector to observe all the teeth without moving the line of sight significantly.

[0057] When it is necessary to remove the flywheel on the positioning rod 21, since the flywheel slides along the positioning rod 21, all the flywheels will fall together. When all the flywheels fall into the collection container, the weight of the entire collection container may be large, and it is not easy for the staff to lift it, which will cause transportation difficulties. Therefore, in order to avoid this problem, after the flywheel is positioned by the positioning rod 21, the motor 17 is used to drive the mounting plate 19 to rotate ninety degrees clockwise, and then according to the number of flywheels that need to be removed at one time, the motor 3 14 is started to drive the threaded rod 2 15 to rotate, so that the threaded block 16 and the slider 11 slide up and down at the same time. , and then use the electric push rod 17 to drive the partition 13 to move, so that the partition 13 is inserted into the gap between adjacent flywheels. At this time, drive the positioning rod 21 away from the flywheel, the flywheel loses its positioning, and will fall downward. The flywheel below the partition 13 will fall into the collection container, and the flywheel above the partition 13 will be intercepted by the partition 13, thereby realizing the staged falling of the flywheel, and the falling amount of the flywheel at one time can be controlled according to actual needs, avoiding the situation where all flywheels fall into the collection container at one time, causing difficulty for the staff to transport due to the heavy weight of the collection container, thereby improving the transportation efficiency.

[0058] The working principle of the present application is as follows: molten metal liquid is added into the crucible 5, and then the electric push rod 3 41 is used to drive the mold 2 4 to descend, and at this time, the left end face of the demoulding rod 37 is flush with the end face of one side of the inner cavity of the mold 1 3. At this time, the mold 1 3, the mold 2 4, and the demoulding rod 37 form a complete molding cavity, and then the air compressor 38 is used to inject compressed air into the crucible 5. After the metal liquid in the crucible 5 is pressurized, it enters the molding cavity through the connecting pipe 6, and then the metal liquid in the molding cavity is cooled. The cooling means for the molten metal is the existing technology and will not be described in detail. The molten metal in the molding cavity is solidified after cooling, and then the electric push rod 3 41 is used again to drive the mold 2 4 to rise. At this time, the extension of the electric push rod 2 39 can be used to drive the connecting plate 31 to move horizontally, so that the demoulding rod 37 moves to the left to eject the molded flywheel, thereby eliminating the need for manual removal of the molded flywheel from the molding cavity. It is more convenient. When the flywheel is about to be ejected from the mold cavity by the demoulding rod 37, the motor 2 8 is used to drive the threaded rod 1 9 rotates to make the mounting frame 2 move to the right, and the plurality of positioning rods 21 are aligned with the inner hole of the flywheel. When the flywheel is separated from the mold 3, it will be sleeved on the positioning rod 21, and then the motor 7 drives the mounting plate 19 to rotate, so that the plurality of positioning rods 21 can be tilted, and the flywheel will slide down to the right end surface of the groove plate 25 under the action of gravity, and then repeat the above operation, so that the plurality of molded flywheels can be sleeved on the positioning rod 21, and the adjacent flywheels can fit each other. When it is necessary to remove the plurality of flywheels, it is only necessary to place a collection container on the positioning rod 21, and then drive the positioning rod 21 to tilt, so that the flywheel slides into the collection container through the positioning rod 21, thereby realizing the unified arrangement and placement of the plurality of molded flywheels, which is relatively neat and convenient for the subsequent unified transportation of the flywheels. At the same time, the neatly arranged flywheels are also easy for the staff to check their appearance quality, and the defective flywheels can be found in time. Moreover, compared with the method of quality inspection for each flywheel formed, this unified inspection is easy to observe and compare, and the inspection efficiency is improved.Since the flywheels are fitted together after being sleeved on the positioning rod 21, the fitting surface of the flywheel will be covered, making it difficult for the staff to observe the appearance quality of this position, resulting in a blind spot for inspection. In order to avoid this situation, whenever a flywheel slides onto the positioning rod 21, the motor 7 42 drives the threaded rod 4 35 to rotate, so that the extrusion rod 18 slides from left to right on the slide rod 3 36. When the end of the extrusion rod 18 contacts the spacer 23, the spacer 23 will be squeezed, so that the end of the spacer 23 is close to the flywheel until it fits with the surface of one side of the flywheel, and then the above operation is repeated. As the number of flywheels on the positioning rod 21 increases, the extrusion rod 18 also squeezes more spacers 23, so that multiple spacers 23 can be placed together using the spacers 23. The flywheels are separated, and there will be no situation where the flywheels fit each other. When the number of flywheels sleeved on the positioning rod 21 reaches a sufficient number, the positioning rod 21 is kept horizontal, and then the extrusion rod 18 is driven to reset to the left again, so that the spacer 23 can be kept away from the flywheel. At this time, the appearance quality of multiple flywheels can be inspected again, which can avoid the situation of blind spots in inspection caused by mutual covering between flywheels, thereby improving the comprehensiveness of appearance quality inspection; and when the staff observes the teeth on the surface of the flywheel, due to the large number of teeth and the arrangement of the teeth around the flywheel, the staff needs to move their sight more significantly to observe all the teeth, which is more troublesome, and the sleeve on the positioning rod 21 The teeth of the flywheel may be in a misaligned state. When the teeth of the flywheel are not aligned, the visual attention of the inspector needs to switch frequently between different flywheels and teeth in an attempt to find a unified reference standard. This frequent switching can easily cause visual fatigue, thereby affecting the accuracy of the inspection. Therefore, in order to avoid the above situation, after the flywheel is mounted on the positioning rod 21, the motor five 28 can be used to drive the threaded rod three 29 to rotate, so that the embedded rod 20 descends and contacts the flywheel. When the embedded rod 20 contacts the flywheel, it squeezes the teeth of the flywheel until it is embedded in the groove between the adjacent teeth. When the embedded rod 20 is embedded in the groove between the adjacent teeth of each flywheel, the teeth of multiple flywheels are aligned. This makes it easier for inspectors to find a unified reference standard, does not easily cause visual fatigue, and improves the accuracy of inspection. Moreover, when the teeth of multiple flywheels are aligned, the embedded rod 20 is driven to extend from the groove of the flywheel, and then the motor 6 32 is used to drive the turntable 34 to rotate, so that the multiple adjustment blocks 40 can be moved radially at the same time under the rotation of the multiple connecting rods 33, until all the positioning rods 21 are in contact with the inner ring of the flywheel, so that the flywheel is positioned. At this time, the motor 4 27 is used to drive the concave plate 26 to rotate, so that the multiple flywheels can be rotated at the same time, and the teeth at various positions of the flywheel are turned toward the inspector, which makes it easier for the inspector to observe all the teeth without moving the line of sight significantly.When it is necessary to remove the flywheel on the positioning rod 21, since the flywheel slides along the positioning rod 21, all the flywheels will fall together. When all the flywheels fall into the collection container, the weight of the entire collection container may be large, and it is not easy for the staff to lift it, which will cause transportation difficulties. Therefore, in order to avoid this problem, after the flywheel is positioned by the positioning rod 21, the motor 17 is used to drive the mounting plate 19 to rotate ninety degrees clockwise, and then according to the number of flywheels that need to be removed at one time, the motor 3 14 is started to drive the threaded rod 2 15 to rotate, so that the threaded block 16 and the slider 11 slide up and down at the same time. , and then use the electric push rod 17 to drive the partition 13 to move, so that the partition 13 is inserted into the gap between adjacent flywheels. At this time, the positioning rod 21 is driven away from the flywheel, and the flywheel loses its position and falls downward. The flywheel below the partition 13 will fall into the collection container, and the flywheel above the partition 13 will be intercepted by the partition 13, thereby realizing the stepwise falling of the flywheel, and the falling amount of the flywheel at one time can be controlled according to actual needs, avoiding the situation where all flywheels fall into the collection container at one time, which makes it difficult for the staff to transport them due to the heavy weight of the collection container, thereby improving the transportation efficiency. ;
