[0029] See Figures 1 to 2An embodiment of a preform elevator, the elevator in this embodiment includes a base frame 1, a vertical lifting device, a hopper 3, and a lifting motor 5. The vertical lifting device is provided with a semi-enclosed shell. The semi-enclosed shell includes Z-shaped left and right side plates 21, 22 and a protective cover 28 mounted on the base frame 1. The left and right side plates 21, 22 are assembled to form an inner cavity. The inner cavity includes first and second horizontal sections 23, 24, first and second redirecting sections 25, 26 and a vertical section 27. The protective cover 28 is connected to the left and right side plates 21, 22 of the vertical section 27 at the rear side of the inner cavity. A conveyor belt 4 is provided in the inner cavity. The conveyor belt is a detachable multi-plate 41 connected to the conveyor. Spoon-shaped baffles 42 perpendicular to the surface of the flat plate 41 are provided at intervals on the belt 4. A tensioning device 43 is provided at the bottom of the conveyor belt 4 near the connection between the first horizontal section 23 and the first redirecting section 25, and a first redirecting wheel 44 is provided near the connection between the first horizontal section 23 and the vertical section 27. A second redirecting wheel 45 is provided at the top of the conveyor belt 4 near the connection between the second horizontal section 24 and the vertical section 27, and a third redirecting wheel 46 is provided near the connection between the second horizontal section 24 and the second redirecting section 26. The conveyor belt 4 is electrically connected to the lifting motor 5; the hopper 3 is fixed on the left and right side plates near the first redirecting section 25 and the conveyor belt passes through the feed port of the hopper 3.

[0030] The elevator of this embodiment is designed with a conveyor belt 4 composed of multiple detachably connected flat plates 41 in a semi-enclosed shell, and scoop-shaped baffles 42 are provided at intervals on the conveyor belt 4. The conveyor belt 4 passes through the hopper 3 and scoops up the bottle preforms in the hopper 3 during the transmission process for lifting and conveying. On the one hand, by reasonably setting the intervals between the scoop-shaped baffles 42, it is possible to ensure that the items on the conveyor belt maintain a certain arrangement and sequence, thereby improving transportation efficiency, and it can also flexibly cope with the transmission of bottle preforms with different outer diameters, thereby improving versatility. On the other hand, when a flat plate 41 or a scoop-shaped baffle 42 is damaged, it can be easily replaced without replacing the entire conveyor belt 4, thereby reducing operating costs.

[0031] In this embodiment, see Figure 3 The left and right side plates 21 and 22 are respectively divided into corresponding lower plates 211, middle plates 212, and upper plates 213. The lower plate 211 and the middle plate 212 are connected by a first connecting plate 210, and the middle plate 212 and the upper plate 213 are connected by a second connecting plate 220. This facilitates assembly when the lifting device is higher, and the semi-enclosed shell is more stable after assembly.

[0032] In this embodiment, the surface of the plate 41 is a mesh structure to increase friction. Figure 4 、 Figure 5, every 2 flat plates 41, a spoon-shaped baffle 42 is arranged in the middle of the third flat plate 41, and the interval of the spoon-shaped baffle 42 is properly arranged, so that the manufacturing and installation costs can be effectively reduced under the premise of ensuring the function implementation, and more moving and arranging spaces are provided for the articles under the premise of ensuring the safety.

[0033] Preferably, the spoon-shaped baffle 42 is integrally formed with the flat plate 41, so as to reduce the assembly components, facilitate the assembly and avoid shaking during the transmission of the bottle embryo. The length of each flat plate 41 is 800 mm, the width is 302 mm, the vertical distance between the outer side of the spoon-shaped end of the spoon-shaped baffle 42 and the flat plate 41 is 76 mm, and the distance between the left and right of the spoon-shaped baffle 42 and the edge of the flat plate 41 is 25-30 mm. In this way, the distance between the spoon-shaped baffle 42 and the edge of the flat plate 41 is controlled, so that the articles placed on the flat plate 41 can be effectively prevented from sliding from the side during the transportation process, and the articles can be stably conveyed.

[0034] The connecting structure is arranged on the opposite sides of the flat plate 41, and in a specific embodiment, the connecting structure comprises a pin hole 411, and the two flat plates 41 are connected through a pin shaft 412. After the two flat plates 41 are connected, the back surface forms a protruding tooth, and the protruding tooth is engaged with the transmission teeth of the first, second and third redirecting wheels 44, 45 and 46 and the tensioning device 43. In this way, the flat plate can improve the connection stability and facilitate the transmission, and can be flexibly redirected after the transmission belt is formed.

[0035] Specifically, the chain track 47 is arranged between the third redirecting wheel 46 and the second redirecting wheel 45, and the tensioning device 43 is a fixed adjustable chain wheel. Therefore, the transmission belt at the first horizontal section and the second horizontal section will not be depressed due to the gravity of the bottle embryo, the bottle embryo material will not be blocked, and the transmission of the bottle embryo will be affected, because of the support of the chain track 47 and the tensioning of the tensioning device 43.

[0036] Preferably, the flat plate 41, the spoon-shaped baffle 42 and the chain track 47 are made of PE material.

[0037] In a specific arrangement, the second horizontal section 23 and the second redirecting section 25 are connected, and the connecting place can correspond to the hopper of the external bottle embryo sorting machine 6. The lifted bottle embryo falls into the hopper of the bottle embryo sorting machine from this place. It should be noted that this place can also correspond to the feeding place of other external conveying devices.

[0038] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the application patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
