[0012] A limiting mechanism is located at the bottom of the placement plate;

[0013] The feeding mechanism is located on the top side inside the C-shaped frame and is used to feed the thermos cups.

[0014] Furthermore, the limiting mechanism includes multiple stop posts disposed at the bottom of the placement plate, and each of the multiple stop posts is rotatably connected to a baffle plate at its bottom.

[0022] 1. This solution involves activating two hydraulic cylinders, which in turn move two arc-shaped clamping plates closer together to secure the thermos. Once secured, two motors are activated simultaneously, and their output shafts rotate the two arc-shaped clamping plates, causing the thermos to flip and stand upright. Then, two push rod motors are activated to place the upright thermos into the groove, where it is stopped by a stop post to prevent it from falling.

[0023] 2. This solution involves starting motor three, which rotates the positioning block, push rod, connecting block, fixing block, and their internal components, causing the two clamping plates to engage with the two slots. Then, starting motor three again reverses the rotation of the positioning block, push rod, connecting block, fixing block, and their internal components, allowing the two baffles to open and the thermos cup to fall into the recycling bin.

[0024] 3. This solution uses the positioning block to continuously compress the spring plate, causing the spring plate to move the rack, which in turn drives the gear to rotate. Through this linkage, the two transmission plates pull the two moving boxes into the connecting block, causing the locking block to disengage from the slot. The baffle can then rebound through the spring to return to its original position.

[0025] This invention enables automatic loading and unloading of thermos cups, eliminating the need for manual loading and unloading and greatly improving work efficiency. Attached Figure Description

[0047] The implementation principle of the automatic loading and unloading inner wall sandblasting device for thermos cups in this application embodiment is as follows: When in use, the thermos cup first falls onto the arc-shaped clamping plate 14 through the outlet. Then, by starting two motors, the output shafts of the two motors simultaneously drive the two rotating shafts 5 and the two partitions 4 to rotate, which can block the thermos cup from continuing to be loaded.

[0048] Then, start the two hydraulic cylinders 2. The two hydraulic cylinders 2 can drive the two arc-shaped clamping plates 14 to move closer to each other, thus fixing the thermos cup. After fixing, start the two motors 2 at the same time. The output shafts of the two motors 2 drive the two arc-shaped clamping plates 14 to rotate, thus flipping the thermos cup and making it upright. Then, start the two push rod motors 2 12, which can place the upright thermos cup in the groove 19 and limit it with the stop post 20 to prevent the thermos cup from falling.

[0049] Then start the motor 16. The motor 16 drives the groove 19 to rotate, so that the thermos cup is directly above the sandblasting pipe 9. Then start the push rod motor 7. The output shaft of the push rod motor 7 drives the sandblasting box 6, the sandblasting recovery box 8, the sandblasting pipe 9, the C-shaped fixing frame 10, the clamping plate 11 and the hydraulic cylinder 1 to move upward. Then, by simultaneously starting the two hydraulic cylinders 1, the output ends of the two hydraulic cylinders 1 simultaneously push the two clamping plates 11 closer to each other, so that the two clamping plates 11 can fix the thermos cup. Then, sandblasting can be performed through the sandblasting pipe 9.

[0050] After sandblasting, the electric motor 16 rotates the thermos cup to directly above the recycling bin 25. Then, the electric motor 3 is started, which drives the positioning block 27, push rod, connecting block 30, fixing block 28, and the internal components of the positioning block 27, fixing block 28, and connecting block 30 to rotate, causing the two clamping plates 11 to respectively engage with the two slots 24. Then, the electric motor 3 is started again, causing the positioning block 27, push rod, connecting block 30, fixing block 28, and the internal components of the positioning block 27, fixing block 28, and connecting block 30 to reverse. Then, the two baffles 21 can be pulled to open them, allowing the thermos cup to fall into the recycling bin 25. During the pulling process, the positioning block 27 continuously compresses the spring plate 29, causing the spring plate 29 to drive the rack 31 to move, which in turn drives the gear 32 to rotate. Wheel 1 32 drives shaft 33 to rotate, shaft 33 drives bevel gear 1 34 to rotate, bevel gear 1 34 drives bevel gear 2 35 to rotate, bevel gear 2 35 drives telescopic rod 36 to rotate, telescopic rod 36 drives shaft 4 37 to rotate, shaft 4 37 drives connecting column 38 to rotate, which in turn causes shaft 4 37, connecting column 38 and telescopic rod 36 to rotate, causing bevel gear 3 39 to drive bevel gear 40 to rotate, bevel gear 40 to drive rotating column 2 to rotate, rotating column 2 to drive gear 2 41 to rotate, gear 2 41 to rotate, which in turn causes rack 2 42 to move downward, and through the two transmission plates 15, the two moving boxes 44 can be pulled into the connecting block 30, causing the locking block 46 to disengage from the slot 24, and the baffle 21 can be rebounded by spring 1 23 to return to its original position, and the above operation can be continued.
