The controller is also electrically connected to the driving part of the transmission channel 1 for controlling the transmission channel 1 and the cart temporary storage mechanism 24 to start according to the received first signal, so as to transfer the powder container 12 located on the transmission channel 1 to the transfer cart 2. The position sensor 22 is also used for sending a second signal to the controller when sensing that the transfer cart 2 is aligned with the storage shelf 3. The controller is also electrically connected to the driving part of the storage shelf 3 for controlling the storage shelf 3 and the cart temporary storage mechanism 24 to start according to the received second signal, so as to transfer the powder container 12 located on the cart temporary storage mechanism 24 to the storage shelf 3.

[0041] like Figure 1 , 3 As shown in Figure 4, the powder container temporary storage device also includes a track, which is connected to the transmission channel 1. Specifically, in this embodiment, the setting direction of the track is perpendicular to the setting direction of the transmission channel 1, and the transmission channel 1 is provided with two sections, and the two sections of the transmission channel 1 are respectively arranged on both sides of the track (the three are arranged in a T shape), and their transmission directions are all towards the direction of the track.

[0042] In this embodiment, the powder container temporary storage device is provided with a transfer station, a storage station and a maintenance station. The transfer station is located at the front end of the transmission channel 1 and is used to place the powder container 12. The storage station is distributed along both sides of the track and is located on one side of the transmission channel 1. The storage shelf 3 is arranged at the storage station; the maintenance station is located at the end of the track and is used to repair the transfer trolley 2 when it fails.

[0043] Specifically, the transmission channel 1 includes a first roller unit, and the first roller unit includes a plurality of second rollers arranged in parallel.

[0044] In this embodiment, a first rack is provided on the track, and the first rack extends along the length direction of the track. The storage shelf 3 is arranged parallel to the transmission channel 1, and a plurality of storage shelves 3 are provided, and the plurality of storage shelves 3 are distributed on one side or both sides of the track. The trolley driving mechanism 21 includes a first driving gear 211, a first motor 214, and a first motor bracket 213. The first driving gear 211 is installed at the bottom of the trolley bracket 25 and meshes with the first rack on the track. The first motor bracket 213 is installed on the trolley bracket 25. The first motor 214 is fixedly installed on the first motor bracket 213, and the output end of the first motor 214 is connected to the first driving gear 211, which is used to drive the first driving gear 211 to rotate, thereby driving the transfer trolley 2 to move along the length direction of the track.

[0045] Specifically, the position sensor 22 uses an encoder, and a gear is connected to the lower end of the encoder. The gear is meshed with the first rack on the track. When the trolley moves, the gear will rotate, and then the encoder will rotate, thereby realizing the detection of the position of the trolley.

[0046] like Figure 4 As shown, the trolley driving mechanism 21 also includes a first unlocking hand wheel 215 and a first fixed bracket 212. The first fixed bracket 212 is fixedly mounted on the trolley bracket 25. The first fixed bracket 212 includes two vertically arranged blocks.

The first motor bracket 213 is provided with a threaded hole. The bottom end of the first unlocking hand wheel 215 is a threaded structure. The first unlocking hand wheel 215 is threadedly connected to the first motor bracket 213. Since the first motor 214 has a power-off self-locking function, when a power-off condition occurs, the first unlocking hand wheel 215 rotates to drive the first motor bracket 213 to rise and fall along the first slide groove, so that the first driving gear 211 is disengaged or engaged with the first rack, and then the transfer trolley 2 can be dragged by external force.

The driving unit is arranged on the slide 236. The driving unit includes a second driving gear 237. The second motor 238 drives the cam 233 to rotate, and the convex part of the cam 233 pushes the slide 236 to slide on the fixed slide rail 235, so that the second driving gear 237 is engaged with the third roller unit 325, and then the second driving gear 237 drives the third roller unit 325 to rotate.

[0048] In this embodiment, the driving unit also includes a fourth motor 239 and a reducer. The fourth motor 239 is arranged on the slide 236. The reducer includes a dual-output reducer and two L-type reducers. The dual-output reducer is installed at the output end of the fourth motor 239, and the two L-type reducers are respectively installed on the output ends of the dual-output reducer. There are two second drive gears 237, and the two second drive gears 237 are respectively installed at the output ends of the two L-type reducers. When one of the second drive gears 237 is engaged with the third roller unit 325 on the storage shelf 3 on one side, the fourth motor 239 drives the second drive gear 237 to rotate, thereby driving the third roller unit 325 to rotate.

[0049] In this embodiment, the shelf driving mechanism 23 further includes a second unlocking hand wheel 231 and a second fixed bracket 234. The second fixed bracket 234 is fixedly mounted on the trolley bracket 25. The second fixed bracket 234 includes two vertically arranged pieces. The two second fixed brackets 234 are arranged opposite to each other and are both provided with a second slide groove. The second motor bracket 232 is slidably arranged in the second slide groove. The second motor bracket 232 is provided with a threaded hole. The bottom end of the second unlocking hand wheel 231 is a threaded structure. The second unlocking hand wheel 231 is threadedly connected with the second motor bracket 232. Since the second motor 238 has a power-off self-locking function, when a power-off condition occurs, the second unlocking hand wheel 231 rotates and drives the second motor bracket 232 to rise and fall along the second slide groove, so that the cam 233 is disengaged from or engaged with the slide 236.

[0050] like Figure 6 As shown, the shelf driving mechanism 23 also includes a spring 2310. Two springs 2310 are symmetrically arranged. The two springs 2310 are arranged at both ends of the slide 236.

The trolley block 2423 is a claw-type structure, which is arranged at the bottom of the second roller unit 245, and the two ends of the trolley block 2423 are on both sides of the second roller unit 245, which are used to limit the powder container 12. The first dial block 2421 is respectively connected to the slide 236, the first trigger component 2424, and the second trigger component 2422. The second trigger component 2422 is used to control the opening and closing of the trolley block 2423. A groove is respectively arranged at both ends of the first dial block 2421. When the slide 236 drives the first dial block 2421 to move in one direction, the groove on the first dial block 2421 and the second trigger component The storage shelf 3 also includes a shelf stopper 321, which is arranged at the entrance end of the storage shelf 3. The shelf stopper 321 always remains in a vertical state in a free state, which is used to prevent the powder container 12 located on the storage shelf 3 from falling. The first trigger component 2424 is used to control the opening and closing of the shelf stopper 321. The movement of the first shift block 2421 also triggers the first trigger component 2424, so that the first trigger component 2424 extends and contacts the shelf stopper 321, thereby causing the shelf stopper 321 to fall to open, thereby connecting the second roller unit 245 and the third roller unit 325, so that the powder container 12 located on the second roller unit 245 enters the third roller unit 325.

[0054] like Fig. 9 , 10 As shown, the storage shelf 3 also includes a shelf bracket 31, a second bracket 323, and a second roller gear set 322. The second bracket 323 is installed on the shelf bracket 31, and the third roller unit 325 is installed on the second bracket 323. The third roller unit 325 includes a plurality of third rollers arranged in parallel. The second roller gear set 322 includes a plurality of second gears meshed in sequence, and a second gear is coaxially connected to a third roller. When the shelf driving mechanism 23 contacts the storage shelf 3, the second driving gear 237 of the driving unit meshes with the second roller gear set 322 to drive the second roller gear set 322 to rotate, thereby driving the third roller unit 325 to rotate.

[0055] Optionally, a limit block 324 is provided at one end of the storage shelf 3 away from the shelf stopper 321 , and the limit block 324 can limit the powder container 12 from excessive displacement and falling from the storage shelf 3 .

[0056] like Fig.11 As shown, the powder container temporary storage device also includes a maintenance mechanism 4. The maintenance station is located at the end of the track. The maintenance mechanism 4 is located on the maintenance station. The maintenance mechanism 4 includes a drum 41, a wire rope 42, a tensioning component 47, and a second shift block 46. The drum 41 is mounted on the track, one end of the wire rope 42 is wound around the drum 41, and the other end of the wire rope 42 is wound around the tensioning component 47. The tensioning component 47 is used to adjust the tension of the wire rope 42. The second shift block 46 is fixed on the wire rope 42 and is connected to the transfer trolley 2 when it fails, so as to transport the transfer trolley 2 to the maintenance station under the traction of the wire rope 42.

[0057] Specifically, the maintenance mechanism 4 also includes a third bracket 45, a guide rail 44, and a second rack 43. The third bracket 45 includes two, and the two third brackets 45 are arranged opposite to each other. The guide rail 44 is arranged between the two third brackets 45 and is close to one of the third brackets 45. The second rack 43 is arranged above the other third bracket 45 and is laid along the direction of the third bracket 45. When the transfer trolley 2 fails, the first unlocking handwheel 215 and the second unlocking handwheel 231 will respectively drive the first motor bracket 213 and the second motor bracket 232 to slide upward along the first fixed bracket 212 and the second fixed bracket 234 to unlock, thereby causing the first driving size and the cam 233 to rise. Therefore, in the process of the wire rope 42 pulling the transfer trolley 2 to the maintenance station, one end of the transfer trolley 2 is slid on the guide rail 44, and the first driving gear 211 at the other end is engaged with the second rack 43.

[0058] like Figure 2 As shown, the powder container temporary storage device further includes a weighing mechanism 11 , which is disposed on the transmission channel 1 and is used to weigh the powder container 12 .

[0059] The working process of the powder container temporary storage device in this embodiment is as follows:
