[0025] The 180-degree rotating mechanism of the sagger of the scheme is suitable for moving the sagger containing battery powder materials to a specified position, clamping it, and rotating the sagger to pour out the materials. First, the sagger containing battery powder materials is moved to the discharge end of the positioning component 2, and the sagger is moved along the guide plate 12 toward the middle direction of the rotating mounting plate 1 by the roller 21. After the sagger is moved to the specified position; the two clamping units 31 of the clamping component 3 are simultaneously moved toward the middle direction of the rotating mounting plate 1, so that the two clamping units 31 clamp the sagger located at the specified position; and then the rotating component 4 drives the rotating mounting plate 1 to move along the arc groove 51, so that the sagger rotates according to the trajectory of the arc groove 51 to pour out the materials in the sagger.

[0028] In this embodiment, Figure 2 As shown, two interlocking wheels 24 are arranged on the same side of the plurality of rollers 21, and the interlocking wheels 24 of two adjacent rollers 21 are interlocked through a connecting chain 25; a driving wheel 23 is arranged on the side of one roller 21 away from the interlocking wheel 24, and is connected to the driving member of the positioning component 2 through the driving wheel 23 to drive the plurality of rollers 21 to rotate.

[0029] Specifically, two interlocking wheels 24 are set at the left ends of the multiple rollers 21, and the two interlocking wheels 24 at the left end of each roller 21 are located on the outside of the left rotating mounting plate 1. The interlocking wheel 24 of the previous roller 21 is connected to the interlocking wheel 24 of the next roller 21 through a connecting chain 25, so as to realize the transmission of the multiple rollers 21; a driving wheel 23 is set at the right end of the roller 21 located on the front side, which is located on the outside of the right rotating mounting plate 1, and a driving member of the adjusting component 2 is set and connected to the driving wheel 23, so as to drive the driving wheel 23 to rotate through the driving member, so as to drive the roller 21 to be transmitted.

[0032] In this embodiment, Figure 2 As shown, a roller 22 is arranged between two adjacent rollers 21 , and a ceramic roller is sleeved on the rollers 21 .

[0033] Specifically, the plurality of rollers 21 and rollers 22 are arranged at intervals, the frontmost side is the roller 21, the positioning component 2 includes five rollers 21 and four rollers 22, the rollers 21 are ceramic rollers, and the positioning component 2 works by the motor of the driving member driving the driving wheel 23 of the roller 21 at the front side, while the roller 21 rotates, the linkage wheel 24 of the roller 21 at the rear side is driven to rotate through the connecting chain 25, so that the linkage wheels 24 of each roller 21 are driven by the connecting chain 25. The wheel 24 rotates to transmit the multiple rollers 21 of the positioning component 2; thereby, the sagger containing the battery powder material runs on the rollers 21, and the rollers 21 drive the sagger to move backward along the guide plate 12. When the sagger moves to the middle position of the rotating mounting plate 1, the blocker 26 blocks the sagger. At this time, the two clamping units 31 of the clamping component 3 move toward the middle direction of the rotating mounting plate 1 at the same time, so that the two clamping units 31 clamp the sagger at the specified position.

[0034] In this embodiment, Figure 3 As shown, the clamping unit 31 includes a driving cylinder 32, a clamping linkage plate 33, a clamping block 1 34 and a clamping block 2 35.

The working end of the driving cylinder 32 is connected to the clamping linkage plate 33 located between the rotating mounting plate 1 and the rotating connecting plate 5. A guide member 36 is respectively arranged on the opposite sides of the clamping linkage plate 33. The two guide members 36 pass through the rotating mounting plate 1 and are respectively connected to the clamping block 1 34 and the clamping block 2 35, so that the driving cylinder 32 drives the clamping block 1 34 and the clamping block 2 35 to move along the guide member 36.

[0035] Specifically, the driving cylinder 32 and the clamping linkage plate 33 are located on the outer side of the rotating mounting plate 1, the clamping block 1 34 and the clamping block 2 35 are arranged opposite to each other and are located on the inner side of the rotating mounting plate 1, two guide columns are respectively arranged on the front and rear sides of the clamping linkage plate 33, and a guide bearing seat is arranged at the position of the rotating mounting plate 1 corresponding to the guide column, and the guide column passes through the corresponding guide bearing seat and is respectively connected to the clamping block 1 34 and the clamping block 2 35, so that the driving cylinder 32 drives the clamping block 1 34 and the clamping block 2 35 to move left and right at the same time.

[0036] In this embodiment, Figure 3 As shown, a clamping opening is provided on one side of the clamping block 1 34 close to the clamping block 2 35, and the clamping opening is provided along the height direction of the side wall of the sagger. A guide wheel group 13 is provided along the length direction of the guide plate 12 away from the side of the rotating mounting plate 1.

Clamping openings are arranged on opposite sides of the clamping block 1 34 and the clamping block 2 35. When the sagger filled with battery powder material runs on the roller 21, the roller 21 drives the sagger to move backward along the guide wheel group 13 on the two guide plates 12. When it moves to the middle position of the rotating mounting plate 1, the sagger is blocked by the blocker 26, and then the driving cylinder 32 of the clamping unit 31 located on the outside of the left rotating mounting plate 1 drives the two clamping blocks to move to the right, and at the same time, the driving cylinder 32 of the clamping unit 31 located on the outside of the right rotating mounting plate 1 drives the two clamping blocks to move to the left. The four clamping blocks of the two clamping units 31 move toward the middle direction of the rotating mounting plate 1 at the same time, and contact the four sides of the sagger through the clamping opening to clamp the sagger, so that the sagger is clamped stably and is not easy to fall off in subsequent work.

[0041] Specifically, two circular rotating mounting plates 1 are arranged opposite to each other and connected by a plurality of struts 11.
