Detailed Implementation

[0017] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0018] like Figure 1 , Figure 2 As shown in the figure, a small stacking device provided by this utility model includes a base 1 and a stacking frame 2 above it. The stacking frame 2 includes two annular guide rails 21 and a connecting frame 22 connecting the two annular guide rails 21. The base 1 is provided with a support and guide assembly and a power component. The support and guide assembly is used to support the annular guide rails 21 and provide guidance for their rotation. The power component is used to drive the stacking frame 2 to rotate. A pressing mechanism is provided between the two annular guide rails 21 to press and fix the product stack 00. A conveying mechanism is provided inside the two annular guide rails 21 and the connecting frame 22 to convey the stacked product stack 00 out.

[0019] As a preferred structure, the support and guide assembly includes four sets of support seats 3 located at the four corners of the base 1. Each set of support seats 3 has a guide wheel 4 on its top that can abut against the outer wall of the annular guide rail 21. The support seats 3 at both ends of the base 1 are connected to the drive shaft 5 and driven shaft 6 of the power component in pairs. In actual manufacturing, the two ends of the drive shaft 5 and driven shaft 6 are respectively rotatably engaged with the support seats through bearings. The two annular guide rails can be placed on the four guide wheels, providing support and guidance for the annular guide rails during rotation.

[0020] In specific embodiments of this utility model, such as Figure 1 , 2 As shown, the power components include a reversing motor 7, a reducer 8, a drive shaft 5, a driven shaft 6, a reversing sprocket 9, and a reversing chain 10. The reversing motor 7 is located on the outside of the base 1 and is connected to the drive shaft 5 through the reducer 8. The drive shaft 5 and the driven shaft 6 are positioned opposite each other at both ends of the base 1. There are four reversing sprockets 9, which are respectively located at the lower part of four sets of support seats 3. The two ends of the drive shaft 5 and the driven shaft 6 pass through two support seats 3 at both ends of the base 1 and are connected to the reversing sprockets 9. The guide wheel 4 is located above the reversing sprockets 9. There are two reversing chains 10, which are respectively wound around the slots of the annular guide rails 21 on both sides and mesh with the reversing sprockets 9 on the support seats 3 at the four corners of the base 1. In specific manufacturing, recessed anti-slip textures can be machined on the arc-shaped bottom surface of the groove of the arc-shaped guide rail to increase the friction between it and the tilting chain without interfering with the cooperation with the guide wheels. The tilting motor adopts a servo motor, and the reciprocating rotation of the tilting frame is achieved by the forward and reverse rotation of the tilting motor. In application, the tilting motor drives the drive shaft and the tilting sprockets at both ends to rotate. The tilting sprockets at both ends then drive the tilting sprockets and driven shaft on the other side to rotate through the tilting chain, thereby realizing the rotation of the two circular guide rails on the four guide wheels.

[0021] Further optimize the above structure, such as Figure 3 , 5As shown, the annular guide rail 21 has protruding eaves on both sides of the slot for limiting the rotation chain 10; one side of the annular guide rail 21 has a protruding arc-shaped limiting plate 20 on its inner edge, and the edge of the support base 3 has a limit switch (not shown in the figure) for sensing the arc-shaped limiting plate 20. The limit switch can be linked with the rotation motor 7. When the arc-shaped limiting plate rotates to the limit switch, the rotation motor automatically stops, realizing precise control of the rotation angle.

[0022] In specific embodiments of this utility model, such as Figure 1 , 4 As shown in Figure 5, the connecting frame 22 includes T-shaped support beams 221 disposed on the upper and lower parts of the annular guide rail 21 and upper and lower crossbeams 222 disposed between the two annular guide rails 21. The two ends of the crossbeams 222 are respectively connected to the T-shaped support beams 221. A support frame for connecting to the conveying mechanism is provided between the T-shaped support beams 221 of the two annular guide rails 21. The pressing mechanism includes two parallel cylinders 13. The cylinder body of the cylinder 13 is disposed on one side crossbeam 222. The piston rod of the cylinder 13 is used to press the product stack 00 between the two rows of rollers 12. The central axis of the cylinder 13 is perpendicular to the central axis of the roller 12. A pressure plate can be installed at the bottom of the piston rod of the cylinder. Two cylinders are sufficient to press and fix the product stack on the rollers.

[0023] In the specific production process, such as Figure 3 , 4 As shown, the support frame includes two parallel support plates 11, with both ends of the support plates 11 extending to the outer side of the annular guide rail 21. Multiple parallel rollers 12 are arranged in rows along the side edges of the two support plates 11. The product stack 00 can be placed between the two rows of rollers 12. A top plate 19 for limiting the position of the product stack 00 is provided opposite to each other in the middle of the two support plates 11. The rollers 12 are driven by a conveying mechanism. The top plate is connected to the support plates by bolts, and the position of the top plate relative to the product stack can be adjusted by the bolts to limit the position of the product stack.

[0024] In specific embodiments of this utility model, such as Figure 2 , 3As shown, the conveying mechanism includes a conveying motor 14, a drive sprocket 15, a conveying chain, and several conveying sprockets 16. The conveying motor 14 is located in the middle of a support plate 11 on one side. The output shaft of the conveying motor 14 is coaxially fixed with the drive sprocket 15. Several conveying sprockets 16 are correspondingly arranged at one end of two rows of rollers. The other end of the rollers is rotatably engaged with the support plate on the other side. The drive sprocket 15 and the conveying sprockets 16 are connected by the conveying chain. The conveying chain includes one drive chain 17 and two driven chains 18. The drive sprocket 15 is connected to the conveying sprockets 16 at one end of the two rows of rollers 12 through the drive chain 17. Two conveying sprockets 16 are arranged side by side at one end of each roller 12 for connection to the drive chain 17 and the driven chains 18. The rollers 12 at the ends of the two rows are connected to the conveying sprockets 16 at the ends of the remaining rollers 12 through two driven chains 18. In practical applications, the drive sprocket can be driven by the conveyor motor to rotate, and then the drive chain can drive the conveyor sprockets at the ends of the two rows of rollers to rotate. The product stacks can be conveyed out. A transfer car can be placed at the discharge end of the support plate to facilitate receiving the output product stacks.

[0025] Further optimize the above solution, such as Figure 6 As shown, adjustable legs 23 are provided at each of the four corners of the base 1. The bottom of the base 1 is connected to the adjustable legs 23 via adjusting bolts 24 for adjusting the height of the base 1. The sides of the base 1 are connected to the adjustable legs 23 via fastening bolts 25. The bottom of the base has threaded holes that mate with the adjusting bolts, and the sides of the adjustable legs have elongated holes. The fastening bolts can move up and down within these elongated holes. This structure allows adjustment of the position of the adjustable legs relative to the base, facilitating the adjustment of the equipment's level.

[0026] In summary, this invention has the advantages of simple and compact structure, high degree of mechanization, and safety and reliability. The product stack is pre-placed on rollers within the flipping frame, and a cylinder is activated to press and fix it in place. Then, the flipping motor is started to rotate the entire flipping frame. When the arc-shaped limit plate on the annular guide rail reaches the limit switch, the flipping motor stops. Subsequently, the conveyor motor is started to transport the flipped product stack out. This invention enables automatic flipping of product stacks without human assistance, ensuring the safety of workers, improving flipping efficiency, reducing the labor intensity of workers, and facilitating widespread application.
