[0009] As a further solution of the present invention, the workstation switching assembly includes a turntable, which is provided with four material lifting troughs, one of which is located directly above the lifting assembly, and the mounting assembly is installed above one of the material lifting troughs and connected to the turntable.

[0013] A method for using a multi-station automatic packaging and stacking device, the method comprising the following steps: The goods to be packed and stacked are placed on the automatic conveying mechanism on the baler, and the automatic conveying mechanism moves the goods to the bottom of the bow frame. The baler is controlled to automatically pack the goods. The packed goods are sent into the stacking frame by the automatic conveying mechanism, and the next goods to be packed are sent to the bottom of the bow frame, so that the goods are in contact with the top material plate, and the multiple limit columns on the top material plate can guide and limit the goods. The electric hydraulic rod is controlled to extend to drive the top material plate to move upward, and the top material plate drives the goods to move upward and contact with the top material plate. The bottoms of the two supporting blocks below are in contact. Since the bottoms of the supporting blocks are designed to be inclined, the two supporting blocks will drive the shaft sleeves to rotate relative to each other outside the connecting shaft after being compressed. When the goods are completely placed above the two supporting blocks, the shaft sleeves and the supporting blocks are driven back by the force of the torsion springs, so that the limit grooves on the supporting blocks are in contact with the stop rods, thereby playing a role in supporting and limiting the supporting blocks, so that the two supporting blocks are in a horizontal state, and the bottoms of the goods are in contact with the supporting grooves on the supporting blocks, so that the two supporting blocks can support the goods, and the stacking of a single cargo can be completed; Secondly, the electric hydraulic rod contracts and drives the top material plate to move down, so that the top of the top material plate and the top of the automatic conveying mechanism are in a horizontal state. After completing the packaging of the next cargo, the automatic conveying mechanism moves the packaged cargo to the top material plate again, and the electric hydraulic rod extends to drive the top material plate and the cargo to move up, so that the cargo on the current top material plate contacts the cargo above. As the cargo at the bottom continues to move up, the cargo above is pressed and squeezes the two supporting blocks above it. Similarly, the cargo on the current top material plate is sent to the two supporting blocks at the bottom. Such reciprocating operation can realize the purpose of automatic packaging and stacking of batch cargo, so that the cargo can be stacked in the stacking rack. After the stacking rack is full of goods, the servo motor is controlled to work, and the servo motor drives the driven gear to rotate through the active gear, and the driven gear drives the turntable to rotate through the fixed shaft. Since the stacking rack is installed on the turntable, the stacking racks are installed on the turntable at the positions corresponding to the ejecting slots. The turntable will drive the stacking rack to rotate ninety degrees, so that another ejecting slot on the turntable is located directly above the ejecting plate, and the empty stacking rack can be moved to the loading position of the automatic conveying mechanism. When the current stacking rack is full of goods, the next stacking rack is switched, and the packaging and stacking of goods can be carried out continuously.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can automatically pack goods by controlling the operation of the packing machine. After packing, the goods are sent into the stacking rack by the automatic conveying mechanism. The electric hydraulic rod is extended to drive the top material plate to move upward, and the top material plate drives the goods to move upward and contact with the bottoms of the two lowest supporting blocks. Because the bottoms of the supporting blocks are inclined, the two supporting blocks will drive the shaft sleeves to rotate relative to each other outside the connecting shaft after being compressed. When the goods are completely placed above the two supporting blocks, the shaft sleeves and the supporting blocks are driven to return to their positions by the force of the torsion springs, so that the limit grooves on the supporting blocks contact with the baffle rods, thereby playing a role in supporting and limiting the supporting blocks, so that the two supporting blocks are in a horizontal state, and the bottoms of the goods contact with the supporting grooves on the supporting blocks, so that the two supporting blocks can support the goods, and the packing is completed. For the stacking of a single cargo, adjust the top plate and the top of the automatic conveying mechanism to be in a horizontal state, and the automatic conveying mechanism moves the packaged cargo to the top plate again. The electric hydraulic rod extends to drive the top plate and the cargo to move upward, so that the cargo currently on the top plate contacts the cargo above. As the cargo at the bottom continues to move upward, the cargo above is compressed and squeezes the two supporting blocks above it. Similarly, the cargo currently on the top plate is sent to the two supporting blocks at the bottom. Such reciprocating operation can achieve the purpose of automatic packaging and stacking of batch cargo. In addition, the stacking stroke will not be interfered with by the stacking position of the cargo during the stacking process. It is only necessary to control the extension and retraction of the electric hydraulic rod. The automatic packaging and stacking equipment with an integrated design is easy to operate and reduces the cost of use, greatly improving the packaging and stacking efficiency.

[0015] 2. The present invention stacks goods in the stacking rack through the ejection plate. After the stacking rack is full of goods, the servo motor is controlled to work, and the servo motor drives the driven gear to rotate through the driving gear, and the driven gear drives the turntable to rotate through the fixed shaft. Since the stacking rack is installed on the turntable, the stacking racks are installed on the positions of the turntable corresponding to the ejection slots. The turntable will drive the stacking rack to rotate ninety degrees, so that another ejection slot on the turntable is located directly above the ejection plate, and the empty stacking rack can be moved to the loading position of the automatic conveying mechanism. When the current stacking rack is full of goods, the next stacking station is switched, so that the packaging and stacking of goods can be carried out continuously, further improving the stacking efficiency of the goods.

As the cargo at the bottom continues to move upward, the cargo above is compressed and squeezes the two supporting blocks 121 above it. Similarly, the cargo currently on the top material plate 142 is sent to the two supporting blocks 121 at the bottom. Such reciprocating operation can realize the purpose of automatic packaging and stacking of batch cargo, so that the cargo can be stacked in the stacking rack 801. After the stacking rack 801 is full of goods, the servo motor 907 is controlled to work, and the servo motor 907 drives the driven gear 905 to rotate through the driving gear 906, and the driven gear 905 drives the turntable 901 to rotate through the fixed shaft 904.

Since the stacking rack (801) is installed on the turntable (901), the stacking racks (801) are installed at positions corresponding to the top material slots (902) on the turntable (901). The turntable (901) drives the stacking rack (801) to rotate ninety degrees, so that another top material slot (902) on the turntable (901) is located directly above the top material plate (142). The empty stacking rack (801) can be moved to the loading position of the automatic conveying mechanism (4). When the current stacking rack (801) is full of goods, the next stacking rack (801) is switched, and the packaging and stacking of goods can be carried out continuously.
