[0013] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments. However, the specific embodiments and examples described below are only for illustrative purposes and are not limitations to the present utility model.

[0014] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the Figure 1 directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0015] In the description of the present application, terms such as "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0016] To solve the above technical problems, as Figures 1 - 3 shown, the present utility model designs a blister turnover pallet unstacking device, which includes a frame 1. A horizontal transmission mechanism 2, a lifting mechanism 3, and a flipping and supporting mechanism 4 are arranged on the frame 1. The horizontal transmission mechanism 2 includes two symmetrically arranged transmission chains 21 on the left and right. The lifting mechanism 3 is arranged in the middle of the frame 1. The lifting mechanism 3 is provided with a lifting plate 31 that can move up and down. The flipping and supporting mechanism 4 includes two symmetrically arranged and rotatable pallet plates 41. The lifting plate 31 is used to support the pallet and can place the lowermost pallet on the transmission chain 21 of the horizontal transmission mechanism 2 after descending. The pallet plate 41 of the flipping and supporting mechanism 4 is used to insert into the second pallet slot from the bottom up to prevent it from falling before the lifting plate 31 descends. Therefore, after the lowermost pallet plate 41 is sent away by the transmission chain 21, the lifting plate 31 of the lifting mechanism 3 can rise, and the pallet plate 41 of the flipping and supporting mechanism 4 disengages to place the pallet on the lifting plate 31. By repeating the cycle, the separation and conveying of each pallet are realized. Through the coordinated work of the horizontal transmission mechanism 2, the lifting mechanism 3, and the flipping and supporting mechanism 4, the automatic unstacking of the pallets is achieved, reducing the need for manual operation and improving the operation efficiency.

[0017] The flipping and supporting mechanism 4 further includes a cross bar 42, side plates 43, a linear cylinder 44, a rotating shaft 45, and a driving rod 46. The two side plates 43 are symmetrically arranged on the left and right of the frame 1. The two ends of the cross bar 42 are fixedly connected to the side plates 43. The cylinder body of the linear cylinder 44 is hinged to the hinge seat on the cross bar 42. The piston rod of the linear cylinder 44 is connected to the driving rod 46. The rotating shaft 45 is arranged outside the side plate 43 through a shaft seat. The driving rod 46 is connected to the rotating shaft 45 and can drive it to rotate. The pallet plate 41 is fixedly connected to the rotating shaft 45. The pallet plate 41 is L-shaped. By providing a stable support point during the flipping process, the flipping and supporting mechanism 4 ensures that the pallet remains stable during the flipping and moving processes, reducing the risk of the pallet tilting or collapsing. The design of the flipping and supporting mechanism 4 usually has a certain degree of flexibility and can adapt to pallets of different sizes and shapes. The automatic flipping and supporting mechanism 4 reduces the chance of direct contact between the operator and heavy objects, reduces the risk of work-related injuries, and improves the safety of the workplace.

[0018] Furthermore, the flipping support mechanism 4 further includes a positioning rod 47. The support plate 41 is provided with a positioning hole adapted to the positioning rod 47. When the support plate 41 rotates to the supporting state, the positioning rod 47 is inserted into the positioning hole of the support plate 41. With the design of the positioning rod 47 and the positioning hole, the flipping support mechanism 4 can ensure the accuracy of the tray when it is flipped to the specified position, guaranteeing the stable operation of the equipment.

[0019] Furthermore, the horizontal transmission mechanism 2 further includes a driving shaft 22, a driving motor 23, and a transmission chain 24. The driving motor 23 is arranged in the middle of the frame 1. The output shaft of the driving motor 23 is connected to the driving shaft 22 through the transmission chain 24. Both ends of the driving shaft 22 are connected to the sprockets of the transmission chain 21. By connecting the output shaft of the driving motor 23 to the driving shaft 22 and using the transmission chain 24 as an intermediary, the stability and efficiency of power transmission can be ensured, energy loss can be reduced. As a mature transmission method, it has high reliability and reduces the downtime caused by transmission system failures.

[0020] Furthermore, the lifting mechanism 3 further includes a lifting cylinder 32, a support plate 33, and a guide rod 44. Two longitudinal rods are arranged in the middle of the frame 1. The support plate 33 is fixed above the longitudinal rods. The lifting cylinder 32 is installed below the support plate 33. The piston rod of the lifting cylinder 32 faces upward and is fixedly connected to the lifting plate 31. A guide sleeve is respectively arranged at the four corners of the support plate 33. The top end of the guide rod 44 is fixedly connected to the lifting plate 31. The guide rod 44 is slidably matched with the guide sleeve. The use of the lifting cylinder 32 provides stable lifting power, ensures the smoothness of the tray during lifting, realizes precise control of the position of the lifting plate 31, improves the accuracy of tray placement. With the use of the guide sleeve and the guide rod 44, the safety during lifting is ensured, preventing the accidental slipping of the lifting plate 31, and at the same time providing good guiding performance, ensuring the linear movement of the lifting plate 31 during lifting.

[0021] Furthermore, a limit railing 5 is also arranged on the frame 1. The limit railing 5 is used to limit the stacked tray group. The setting of the limit railing can prevent the stacked trays in storage from collapsing and skewing, guaranteeing the stability of the storage state.
