Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3This utility model provides a technical solution: a pallet stacking machine, including a frame 1. A sprocket drive assembly 3 is installed on the inner walls of both sides of the frame 1. The sprocket drive assembly 3 includes a driven sprocket 31 and a drive sprocket 32, rotatably connected to the inner walls of the frame 1 and distributed vertically. The driven sprocket 31 is rotatably connected to the side wall of the frame 1 via a bearing seat, and the drive sprocket 32 ​​is rotatably connected to the bottom frame 2 of the frame 1 via a bearing seat. The drive sprocket 32 ​​and the driven sprocket 31 are connected by a chain. A toothed assembly 4 is connected to the chain. The operation of the chain controls the vertical movement of the toothed assembly 4. The toothed assembly 4 is used to clamp a pallet 6 and can drive the clamped pallet 6 to move vertically. A bottom support assembly 5 is fixed on the outer walls of both sides of the frame 1. The bottom support assembly 5 includes a bottom support fixing seat 51 fixed to the outer surface of the frame 1. The bottom support fixing seat 51 is bolted to the outer surface of the frame 1. A guide rail 52 and a cylinder mounting base 56 are bolted to the fixed base 51. The cylinder mounting base 56 is located on one side of the guide rail 52. A bottom-supporting cylinder 57 is fixed on the side of the cylinder mounting base 56. A guide block 53 slides on the guide rail 52. A support rod base 54 is fixed on the guide block 53. A support rod 55 is connected between the support rod bases 54 on both sides of the frame 1. The support rod base 54 is connected to the output end side of the bottom-supporting cylinder 57. When the bottom-supporting cylinder 57 extends, the support rods 55 on both sides move inward to support the stacked pallets 6. The unstacked pallets 6 are placed on the support rods 55 to ensure that the conveyor line below the support rods 55 is unobstructed, allowing other pallets 6 of different specifications to be discharged from the stacking machine. When the target pallet 6 enters the stacking machine, the support rods 55 move outward. The toothed assembly 4 lowers the target pallet 6 to the top of the newly entered target pallet 6 to complete the stacking.

[0022] like Figure 4 As shown, a groove 541 is provided on the side of the support rod base 54, and a concave ring is provided on the output end of the bottom support cylinder 57. The two sides of the groove 541 are embedded in the concave ring, connecting the output end of the bottom support cylinder 57 to the support rod base 54, which facilitates the connection between the bottom support cylinder 57 and the support rod base 54 and enhances the connection strength between the bottom support cylinder 57 and the support rod base 54.

[0023] like Figure 5 and 6As shown, the tooth assembly 4 includes a tooth base plate 43 and a tooth frame 42. The tooth frame 42 is bolted or directly welded to the tooth base plate 43. Slide rails 46 are bolted to both ends of the lower surface of the tooth base plate 43. A slider 47 slides on the slide rails 46. The lower end of the slider 47 is connected to a tooth 48. A cylinder connector 44 is connected to the upper surface of the tooth 48. A tooth cylinder 45 is fixed on the tooth base plate 43. The output end of the tooth cylinder 45 is connected to the cylinder connector 44. By extending or retracting the output end of the tooth cylinder 45, the cylinder connector 44 is extended or retracted, which in turn extends or retracts the tooth 48. The tooth 48 extends and inserts into the hollow groove on the side of the tray 6 to complete the clamping of the tray 6.

[0024] The upper end of the tooth frame 42 is connected to a top plate 41. The upper end of the top plate 41 and the lower end of the tooth base plate 43 are both connected to chain connecting rollers 49. The upper end of the chain connecting roller 49 has a connecting hole on the vertical axial surface. One end of the chain is inserted into the connecting hole, and the two ends of the pin at the end of the chain connect the chain connecting roller 49 and the chain through chain plates, so that the up and down movement of the chain drives the tooth assembly 4 to rise and fall.

[0025] A linear bearing 410 is also connected to the gear base plate 43. Two guide rods 33 are fixed on the inner wall of the frame 1. The two guide rods 33 are located on both sides of the chain. The linear bearing 410 is sleeved on the guide rods 33. The guide rods 33 guide the vertical movement of the linear bearing 410, and further guide the lifting and lowering of the gear assembly 4.

[0026] The lower part of the frame 1 is connected to the bottom frame 2. The lower end of the bottom frame 2 is connected to the output shaft 9 through the bearing seat. The drive sprocket 32 ​​is sleeved on both ends of the output shaft 9. The lower end of the bottom frame 2 is also fixed with the output motor 8. The middle part of the output shaft 9 is also fixed with the sprocket. The output motor 8 is connected to the sprocket on the output shaft 9 through a chain. The output motor 8 controls the rotation of the output shaft 9, so that the output shaft 9 drives the drive sprocket 32 ​​to rotate, which in turn makes the chain run, providing power for the up and down movement of the gear assembly 4.

[0027] The side of the tooth-inserting frame 42 is connected to a sensing bracket 71, and the side of the frame 1 is connected to multiple vertically distributed photoelectric sensors 7. The vertical movement of the tooth-inserting assembly 4 drives the sensing bracket 71 to move vertically into different photoelectric sensors 7. Based on the response of different photoelectric sensors 7, the position of the tooth-inserting assembly 4 and the tray clamping height can be determined.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
