DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0040] See also Figures 1-12 , the utility model provides a technical solution of an electromagnetic rotating material stopper. Example 1

[0041] like Figure 1-Figure 7 As shown, an electromagnetic rotary material stopper comprises:

[0042] A rotating seat 1, wherein a rotating hole 2 is provided in the rotating seat 1;

[0043] The rotating shaft 3 passes through the rotating hole 2 and is rotatably connected to the rotating hole 2. The rotating shaft 3 includes a driving end 4 and a driven end 5. The driving end 4 and the driven end 5 are respectively located on both sides of the rotating base 1;

[0044] A blocking rod 6, one end of which is fixedly connected to the driven end 5;

[0045] Permanent magnet 7, which is fixed to driving end 4. The permanent magnet is radially magnetized at both ends. The permanent magnet 7 includes an N pole 8 and an S pole 9.

[0046] The electromagnetic drive component includes an electromagnetic drive member and a stator. The stator includes a first half ring 10 and a second half ring 11. The first half ring 10 and the second half ring 11 are arranged on the outside of the permanent magnet 7. The electromagnetic drive member is used to change the magnetism of the first half ring 10 and the second half ring 11.

[0047] When the electromagnetic drive is energized in the forward direction, the magnetism of the first half ring 10 changes to the north pole, and the magnetism of the second half ring 11 changes to the south pole. This causes the first half ring 10 to attract the south pole 9 of the permanent magnet 7, while the second half ring 11 attracts the north pole 8 of the permanent magnet 7. When the electromagnetic drive is energized in the reverse direction, the magnetism of the first half ring 10 changes to the south pole, and the magnetism of the second half ring 11 changes to the north pole. This causes the first half ring 10 to attract the north pole 8 of the permanent magnet 7, while the second half ring 11 attracts the south pole of the permanent magnet 7. This drives the rotating shaft 3 to rotate 90°, thereby driving the retaining rod 6 to rotate 90°. Simply by changing the direction of the current flowing through the electromagnetic drive, the retaining rod 6 can be driven to rotate 90° back and forth, and the rotational state of the rotating shaft after its initial state can be detected. Compared to existing drive systems using a drive motor and reducer, this system is much more cost-effective.

[0048] like Figure 2 and Figure 3 As shown, the stator also includes a first iron core 12 and a second iron core 13. The first iron core 12 and the second iron core 13 are made of soft magnetic material. The first iron core 12 and the second iron core 13 are arranged in parallel. The first iron core 12 and the second iron core 13 are fixed on the rotating seat 1. A first connecting block 14 is fixed on the first iron core 12, and a second connecting block 15 is fixed on the second iron core 13. The first connecting block 14 and the second connecting block 15 are fixed together. The first half ring 10 is fixed at one end of the first iron core 12, and the second half ring 11 is fixed at one end of the second iron core 13. The electromagnetic driving component is configured as a driving coil 16, and the driving coil 16 is sleeved on the first connecting block 14 and the second connecting block 15.

[0049] Current can be supplied to the driving coil 16 . Changing the direction of the current supplied to the driving coil 16 can change the polarity of the first half ring 10 and the second half ring 11 , thereby changing the reciprocating 90° rotation of the blocking rod 6 .

[0050] like Figure 3 As shown, the first half ring 10, the first iron core 12 and the first connecting block 14 are integrally formed, the second half ring 11, the second iron core 13 and the second connecting block 15 are integrally formed, the first iron core 12 and the first connecting block 14 are provided with a first through hole 17, the second iron core 13 and the second connecting block 15 are provided with a second internal threaded hole, and the first through hole 17 is penetrated by a first connecting bolt 18 threadedly connected to the second internal threaded hole.

[0051] The first connecting block 14 is inserted into one side of the coil, and the second connecting block 15 is inserted into the other side of the coil, and then the first connecting block 14 and the second connecting block 15 are fixed together using a first connecting bolt 18 .

[0052] The following is another way of stator. Figure 6 and Figure 7 The first iron core 12 is integrally formed with the first half ring 10, the second iron core 13 is integrally formed with the second half ring 11, and the first connecting block 14 and the second connecting block 15 are integrally formed. The first iron core 12 is provided with a first bolt hole 36, through which a first fixing bolt 37 threadedly connected to the first connecting block 14 is passed. The second iron core 13 is provided with a second bolt hole 38, through which a second fixing bolt 39 threadedly connected to the second connecting block 15 is passed.

[0053] The driving coil 16 is first put on the first connecting block 14 and the second connecting block 15, and then the first connecting block 14 is fixed to the first iron core 12 with the first fixing bolt 37, and the second connection is fixed to the second iron core 13 with the second fixing bolt 39. Then the first iron core 12 and the second iron core 13 are fixed to the rotating seat 1. The installation is very convenient.

[0054] like Figure 1 As shown, the rotating base 1 is provided with a mounting slot 19, which is connected to the rotating hole 2. A sensing element 20 is fixed to the rotating shaft 3 and located within the mounting slot 19. A first sensor 21 is fixed to each side of the mounting slot 19, and the first sensor 21 is configured as a proximity switch. When the retaining rod 6 rotates to one side, the sensing element 20 approaches one of the first sensors 21, which receives an electrical signal. When the retaining rod 6 rotates 90°, the sensing element 20 approaches the other first sensor 21, which also receives an electrical signal. Other logistics and transportation devices can perform corresponding actions based on the electrical signals.

[0055] like Figure 3 As shown, the material stopper further includes a coil skeleton 22 . The coil skeleton 22 is sleeved on the first connecting block 14 and the second connecting block 15 , and the driving coil 16 is sleeved on the coil skeleton 22 .

[0056] like Figure 1 and Figure 5 As shown, the material blocking rod 6 includes a circular portion 23 and a rod body 24, one end of the rod body 24 is fixedly connected to the circular portion 23, a first limiting portion 25 is provided at the connection between the rod body 24 and the circular portion 23, and a second limiting protrusion 26 is provided on the circular portion 23, and a limiting protrusion 35 is fixed on the rotating seat 1 facing away from the permanent magnet 7, and the limiting protrusion 35 is arranged between the first limiting portion 25 and the second limiting protrusion 26.

[0057] When the blocking rod 6 rotates, the first limiting portion 25 and the second limiting protrusion 26 can play a limiting role to prevent the blocking rod 6 from rotating excessively.

[0058] like Figure 2 and Figure 3 As shown, the material stopper further includes a C-shaped protective sleeve 33 , in which a baffle 34 is fixed. The driving coil 16 is located on the inner side of the baffle 34 in the C-shaped protective sleeve 33 , and the C-shaped protective sleeve 33 can achieve a protective effect. Example 2

[0059] like Figures 8-12 As shown, the difference between this embodiment and the first embodiment lies in the different structure of the stator. The stator further includes an outer frame 27, with a first inner connecting block 28 and a second inner connecting block 29 fixed to opposite sides of the inner wall of the outer frame 27. The first half ring 10 is fixed to the first inner connecting block 28, and the second half ring 11 is fixed to the second inner connecting block 29. The electromagnetic drive component is configured as an induction coil 40, which is wound around the first and second inner connecting blocks 28 and 29. As in the embodiment, current can be passed through the induction coil 40. Changing the direction of the current passed through the induction coil 40 can change the polarity of the first half ring 10 and the second half ring 11, thereby changing the reciprocating 90° rotation of the material blocking rod 6.

[0060] like Figure 8 As shown, a sensing piece 30 is fixed to one end of the rotating shaft 3 extending from the outer frame 27, and a second sensor 31 is fixed to the side of the outer frame 27 facing away from the rotating base 1. The second sensor 31 is provided with a sensing slot 32 for the sensing piece 30 to pass through. When the sensing piece 30 is inserted into the sensing slot 32, an induced electrical signal can be obtained, thereby determining the position of the material blocking rod 6.
