The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 2 to 4, the present invention provides a paper inserting apparatus, including a frame 100 and a stator clamping mechanism 200, wherein the stator clamping mechanism 200 includes a clamping plate 210 and a plurality of first stator connecting members 220, the clamping plate 210 is mounted on the frame 100, the clamping plate 210 has a clamping space 211 for accommodating a group circular stator 20, at least one side of the clamping space 211 is open, so that insulating paper can enter and exit the clamping space 211 through the open, the first stator connecting members 220 are used for detachably connecting with block stators 10 of the group circular stator 20, the plurality of stator connecting members are circumferentially spaced apart from each other along the clamping space 211, and the first stator connecting members 220 are slidably mounted on the clamping plate 210 along a radial direction of the clamping space 211.

Wherein, circle of group stator 20 packs into clamping space 211 after, first stator connecting piece 220 is connected with blocking stator 10, and drive blocking stator 10 along clamping space 211 radially towards keeping away from the center slip of clamping space 211, then the paper inserting gap increase between the adjacent blocking stator 10, be convenient for insulating paper inserts in the paper inserting gap, treat that insulating paper installs after target in place, blocking stator 10 slides towards the center that is close to clamping space 211 along clamping space 211 radially, make whole circle of group stator 20 compact structure, the technical problem of defective products has been solved to current paper inserting operation easy appearance, thereby circle of group stator 20's rate has been improved.

Optionally, an opening is formed below the clamping space 211, and the insulation paper enters the clamping space 211 through the opening and is inserted into the paper insertion gap between the adjacent segmented stators 10.

In some embodiments, referring to fig. 4, the stator clamping mechanism 200 further includes a clamping limiting member 230 movably mounted on the clamping plate 210, and the clamping limiting member 230 has a limiting surface 231 corresponding to the first stator connecting member 220. That is, the number of the position-limiting surfaces 231 is the same as the number of the first stator-connecting members 220, and the positions thereof correspond to each other.

In an embodiment, the limiting surface 231 abuts against the first stator connecting element 220 to drive the first stator connecting element 220 to slide along the radial direction of the clamping space 211.

For example, each first stator connecting element 220 corresponds to two limiting surfaces 231. Optionally, when the clamping limiting member 230 moves along the first direction, one of the limiting surfaces 231 may push the first stator connecting member 220 to slide outward along the radial direction of the clamping space 211 by abutting against the first stator connecting member 220. When the clamping limiting member 230 moves along the second direction, the other limiting surface 231 can abut against the first stator connecting member 220, so as to push the first stator connecting member 220 to slide inward along the radial direction of the clamping space 211. That is, the first stator connecting element 220 is located between the two limiting surfaces 231, so that the first stator connecting element 220 can be pushed to reciprocate along the radial direction of the clamping space 211.

For another example, the number of the limiting surfaces 231 is one, the limiting surfaces 231 can push the first stator connecting piece 220 to slide inward along the radial direction of the clamping space 211 by abutting against the first stator connecting piece 220, and the other force application structure applies a force to the first stator connecting piece 220 to slide outward along the radial direction of the clamping space 211, so that the first stator connecting piece 220 makes a reciprocating motion along the radial direction of the clamping space 211 under the combined action of the clamping limiting piece 230 and the force application structure.

For example, referring to fig. 5 and 6, the stator clamping mechanism 200 further includes an elastic member 240 mounted to the clamping plate 210, the elastic member 240 being used to apply a force to the first stator coupler 220 away from the center of the clamping space 211. When the limiting surface 231 is withdrawn outward in the radial direction of the clamping space 211, the first stator connecting element 220 slides outward in the radial direction of the clamping space 211 under the pushing of the elastic element 240. When the limiting surface 231 advances inward along the radial direction of the clamping space 211, the first stator connecting element 220 overcomes the elastic force applied by the elastic element 240 and slides inward along the radial direction of the clamping space 211 under the pushing of the limiting surface 231.

Optionally, the elastic member 240 is a spring.

In another embodiment, the limiting surface 231 is connected to the first stator connecting element 220 to drive the first stator connecting element 220 to slide along the radial direction of the clamping space 211, so that the clamping limiting element 230 reciprocates along the radial direction of the clamping space 211 to drive the first stator connecting element 220 to reciprocate along the radial direction of the clamping space 211.

In one embodiment, referring to fig. 3 and 4, the clamping limiter 230 is rotatably mounted on the clamping plate 210, and the limiting surface 231 has a first position and a second position, wherein the first position is spaced from the center of the clamping space 211 by a radial distance different from the second position, which is spaced from the center of the clamping space 211 by a radial distance.

Assuming that the radial distance between the first position and the center of the clamping space 211 is greater than the radial distance between the second position and the center of the clamping space 211, when the clamping limiting member 230 rotates to make the first position of the limiting surface 231 contact with the first stator connecting member 220, the first stator connecting member 220 slides outward along the radial direction of the clamping space 211. When the clamping limiting member 230 rotates to make the second position of the limiting surface 231 contact with the first stator connecting member 220, the first stator connecting member 220 slides inward along the radial direction of the clamping space 211.

Optionally, the limiting surface 231 is an arc surface.

Specifically, the coupling force of the second stator connector 340 with the block stator 10 is smaller than that of the first stator connector 220 with the block stator 10.

For example, the second stator connector 340 includes a second magnet, and the attraction force of the second magnet is smaller than that of the first magnet, so that the segmented stator 10 is attracted to the first magnet by being separated from the second magnet.

For another example, the first stator connector 220 is fixed to the segmented stator 10 by clamping. When the fixed cylinder 330 descends into the clamping space 211, the first stator connecting piece 220 is fixedly clamped with the block stator 10; when the fixed cylinder 330 leaves the clamping space 211 through the opening, the coupling force of the first stator connector 220 with the block stator 10 is greater than the coupling force of the second stator connector 340 with the block stator 10, and then the second stator connector 340 is separated from the block stator 10 and moves upward along with the fixed cylinder 330.
