DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The utility model aims to provide a large and small head type magnetic steel vibration sorting device to solve the problems existing in the prior art, realize the automation of the feeding process of the large and small head magnetic steel in a specific state, and save manual labor.
[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0026] like Figure 1-Figure 5As shown, this embodiment provides a vibration sorting device for large and small head type magnetic steels, including a vibration plate 1, a first sorting module, a second sorting module and a third sorting module. A conveying track is arranged in the vibration plate 1, and the lower end of the conveying track is located on the inner bottom surface of the vibration plate 1, and the upper end of the conveying track spirally extends upward. The first sorting module, the second sorting module and the third sorting module are all installed on the conveying track and arranged in sequence along the length direction of the conveying track, and then the large and small head type magnetic steels 5 in various states are screened in sequence through the three processes of the first sorting module, the second sorting module and the third sorting module. The first sorting module can make the large and small head type magnetic steels 5 in the prone state pass through, while the large and small head type magnetic steels 5 in the upright state fall into the vibration plate 1 and are re-transmitted, so that the large and small head type magnetic steels that reach the second sorting module are The head-type magnets 5 are all in an inverted state, and the second sorting module can flip the inverted large and small head-type magnets 5 into an upright state, thereby making the large and small head-type magnets 5 entering the third sorting module all in an upright state, and the third sorting module can make the large and small head-type magnets 5 with small heads facing downward pass and be discharged, while the large and small head-type magnets 5 with large heads facing downward fall into the vibration disk 1 and are re-transmitted, thereby making the large and small head-type magnets 5 sorted by the third sorting module all in an upright state with the small heads facing downward, completing the precise adjustment of the large and small head-type magnets 5, thereby meeting the requirements for correct polar magnetization of the large and small head-type magnets 5 in batches, and at the same time, automated operation can greatly save manual labor and greatly improve production efficiency. This method is simple and effective, easy to popularize, and at the same time meets the needs of mass production.
[0027] Specifically, the conveying track is an L-shaped track, and the angle between the upper bottom surface of the L-shaped track and the horizontal plane is an acute angle, so that the upper bottom surface of the L-shaped track is inclined, which can stably support the large and small head magnets 5 and prevent them from falling through the L-shaped track during vibration, affecting the sorting efficiency.
[0028] The angle between the bottom surface of the L-shaped track and the horizontal plane is 20°-40°, which allows the large and small head magnets 5 to vibrate forward on the conveying track without turning over and falling. Those skilled in the art can make adaptive changes to the above specific parameters according to actual needs.
[0029] The present embodiment also includes a first feeding track 21, a second feeding track 31 and a third feeding track 33 which are sequentially arranged and connected along the extension direction of the conveying track. The first feeding track 21 is connected to the upper end of the conveying track. The conveying track is used to convey the large and small head type magnetic steel 5 to the first feeding track 21 under the vibration action of the vibration disk 1 for subsequent sorting process. The first sorting module is installed on the first feeding track 21, and the first feeding track 21 is used to convey the large and small head type magnetic steel 5 in a prostrate state sorted by the first sorting module to the second sorting module under the vibration action of the vibration disk 1, and the large and small head type magnetic steel 5 in an upright state falls into the vibration disk 1. The second sorting module is installed on the second feeding track 31, and the second feeding track 31 is used to convey the large and small head type magnetic steel 5 to the second sorting module under the vibration action of the vibration disk 1. At the selection module, the second sorting module can flip the large and small head type magnetic steel 5 in the inverted state, and transfer the flipped large and small head type magnetic steel 5 to the third feeding track 33. After the flipping is completed, the large and small head type magnetic steel 5 in the upright state with the small head facing downward can smoothly enter the third feeding track 33, so as to be sorted by the subsequent third sorting module. As for the large and small head type magnetic steel 5 in the upright state with the large head facing downward, and the large and small head type magnetic steel 5 that is still in the inverted state after flipping, they cannot be hung on the third feeding track 33 and fall into the vibration disk 1, so that the large and small head type magnetic steel 5 entering the third feeding track 33 are all in the upright state with the small head facing downward. The third feeding track 33 is used to sort and transfer the large and small head type magnetic steel 5 to the discharge port under the vibration of the vibration disk 1, and the third sorting module is installed at the end of the third feeding track 33. The first feeding track 21 and the first sorting module form a first sorting area 2 , the second feeding track 31 , the second sorting module and the third feeding track 33 form a second sorting area 3 , and the third sorting module forms a third sorting area 4 .
[0030] The upper bottom surfaces of the first feeding track 21 , the second feeding track 31 and the third feeding track 33 all have acute angles with the horizontal plane, thereby ensuring stable support and transportation of the large and small head type magnetic steels 5 .
[0031] The first sorting module is a first sorting rod 22, one end of which is fixed on the inner wall of the first feeding track 21, and the other end of the first sorting rod 22 extends in the direction of movement of the large and small head magnets 5 and the direction of the central axis of the vibration disk 1, and the distance between the first sorting rod 22 and the inner bottom surface of the first feeding track 21 is greater than the maximum diameter of the large and small head magnets 5, and less than the height of the large and small head magnets 5. Therefore, when the large and small head magnets 5 pass through the first sorting rod 22, as each large and small head magnet 5 moves, the large and small head magnets 5 in an upright state are knocked down by the first sorting rod 22 and fall into the vibration disk 1, while the large and small head magnets 5 in a prone state will not contact the first sorting rod 22, and thus smoothly enter the second feeding track 31.
[0032] The second feeding track 31 extends to the outer wall of the inner ring of the vibration disk 1; the second sorting module is the second sorting plate 32, and the second sorting plate 32 includes a transverse plate and a longitudinal plate. The upper end of the longitudinal plate is connected to the end of the second feeding track 31 and transitions smoothly, and the lower end of the longitudinal plate is fixedly connected to one end of the transverse plate. When the large and small head type magnetic steels 5 in the inverted state fall onto the transverse plate through the second feeding track 31, they will flip over due to the action of gravity and then turn into an upright state. The other end of the transverse plate extends to the bottom of the third feeding track 33 to transport the large and small head type magnetic steels 5 in the upright state to the third feeding track 33.
[0033] The third feeding track 33 is fixed on the outer wall of the inner ring of the vibration plate 1, and the distance between the upper end surface of the third feeding track 33 and the upper end surface of the transverse plate is equal to the height of the small head of the large and small head type magnetic steel 5 (in the actual processing process, the specific value can be adaptively slightly changed according to the processing needs), and then when the large and small head type magnetic steel 5 is transmitted to the third feeding track 33, the lower edge of the large head of the large and small head type magnetic steel 5 with the small head facing downward can just hang on the third feeding track 33, and move toward the discharge port under the action of the third feeding track 33, and the distance between the upper end surface of the third feeding track 33 and the upper end surface of the transverse plate is equal to the height of the small head of the large and small head type magnetic steel 5. The height of the big head of the large and small head magnet 5 is smaller than that of the big head of the large and small head magnet 5, and when the large and small head magnet 5 with the big head facing downward and the large and small head magnet 5 in a lying state are transmitted to the third feeding track 33, the third feeding track 33 contacts the outer wall of the big head of the large and small head magnet 5. At the same time, since the width of the transverse plate is greater than the diameter of the small head of the large and small head magnet 5, and is less than or equal to the diameter of the big head of the large and small head magnet 5, the transverse plate can no longer support the large and small head magnet 5 with the big head facing downward, so that the large and small head magnet 5 with the big head facing downward falls into the vibration disk 1, and all the large and small head magnets 5 remaining on the third feeding track 33 have their small heads facing downward.
[0034] The third sorting module includes a third sorting block 41 and a guide block 42. The third sorting block 41 is provided with a feeding hole. The guide block 42 is installed above the third sorting block 41 and is located on the side of the feeding hole close to the third feeding track 33. The lower end of the third sorting block 41 is connected to one end of a discharge pipe 43, and the other end of the discharge pipe 43 extends to the outside. The large and small head type magnetic steels 5 on the third feeding track 33 can slide downward through the material hole and the discharge pipe 43 to enter the magnetizer. The large and small head type magnetic steels 5 entering the discharge pipe 43 are all arranged in an orderly and directional manner, and all enter the discharge pipe 43 with the small head facing downward and the large head facing upward, so that the large and small head type magnetic steels 5 can be neatly and accurately transported to the magnetization process, ensuring the consistency and correctness of the polarity of the large and small head type magnetic steels 5 in the magnetization process.
[0035] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
