Description

Technical Field

[0001] The invention relates to the technical field of tray loading machines, and in particular to a tray lifting mechanism of an automatic tray loading machine. Background Art

[0002] In the industrial production process, the tray loading machine is a key equipment for automatically handling tray materials, and is widely used in production lines that require trays to be placed and arranged in an orderly manner. Its main function is to arrange the trays accurately and neatly through mechanized lifting and positioning, reducing the complexity and labor intensity of manual operations, and improving production efficiency and product consistency.

[0003] At present, the loading machines on the market mostly use multiple drive sources to cooperate with each other to achieve complex action combinations such as lifting, moving, and positioning. However, in actual use, the coordinated operation between different drive components is often not convenient enough. This inconvenience is mainly reflected in the poor synchronization between the drive systems, complex debugging, and limited control accuracy, which affects the response speed and work efficiency of the equipment.

[0004] In view of the above problems, we have introduced a plate lifting mechanism for an automatic plate loading machine. Summary of the invention

[0005] The invention discloses a tray lifting mechanism of an automatic tray loading machine, aiming to solve the technical problems in the background technology.

[0008] The lifting device includes a bracket and a plate shell, wherein two brackets are provided and are symmetrically arranged, the inside of the bracket is symmetrically rotatably connected to two rotating shafts, the outer sides of the rotating shafts are symmetrically fixedly connected to two first connecting plates, a connecting shaft is fixedly connected between the two first connecting plates, the outer sides of the connecting shafts are symmetrically rotatably connected to two second connecting plates, one side of the plate shell is symmetrically fixedly connected to two reinforcing columns, the second connecting plates are fixedly connected to the corresponding reinforcing columns, and the outer side of the plate shell is equidistantly fixedly connected to storage plates.

[0009] When the rotating shaft rotates, it can drive the connecting shaft to swing. When the connecting shaft swings, it can drive the second connecting plate to move, and then drive the reinforcement column and the plate shell to move through the second connecting plate. Through the repeated swinging of the rotating shaft, the repeated movement of the plate shell can be realized. When the plate shell moves outward, it can clamp the disk body, and when the disk body rises, the plate shell moves inward to avoid the position.

The moving frame is arranged between the two fourth connecting plates, and the fourth connecting plates are rotatably connected to the corresponding moving frames. The outer side of the moving frame is symmetrically fixedly connected to a lifting tooth plate.

[0011] When the mobile frame is moving and the rotating shaft is swinging, it can also drive the third connecting plate to swing, and when the third connecting plate rotates, it can drive the fourth connecting plate to rotate, so that the mobile frame can be reinforced to ensure that the mobile frame can move stably.

[0014] In a preferred solution, the fixed plate is configured as an L-shaped structure, a vertical guide rail is provided on one side of the fixed plate, a vertical sliding plate is connected to the vertical guide rail, and the vertical sliding plate is arranged between two reinforcement columns, wherein a lifting plate is fixedly connected to the vertical sliding plate located below, an upper contact roller is rotatably connected to the lifting plate, and the upper contact roller is rollingly connected to the cam.

[0015] When the cam rotates, it will also move up and down with the upper contact roller, so that the lifting plate can be driven to move up and down, and then the vertical moving plate can be driven to move up and down through the lifting plate.

[0018] In a preferred solution, the fixed plate is connected to an inclined guide rail on one side away from the vertical guide rail, the inclined guide rail is connected to an inclined plate, the inclined plate is fixedly connected to a connecting lug, and the second pull rod is rotatably connected to the connecting lug via a fisheye bearing.

[0019] During the swinging process, the rotating plate can drive the second pull rod to move, and during the movement process, the second pull rod can drive the inclined displacement plate to move through the connecting lug.

[0021] The second connecting rod can drive the moving frame to move forward and backward, and the position of the inclined slot will change during the lifting process of the vertical moving plate, so that the two reinforcement columns can be driven to move forward and backward through the fixed shaft and the inclined slot. Since it is an inclined slot, the reinforcement column will move forward and backward horizontally;

[0022] The moving frame contacts the vertical slot in the inclined plate through the latch pin, so that when the moving frame is moving, it can avoid position through the vertical slot, thereby enhancing the stability of the moving frame during movement.

[0023] In a preferred solution, a tension spring is connected between the lifting plate and the rotating plate.

[0024] The rotating plate and the lifting plate can be quickly reset by means of a tension spring.

[0025] In a preferred solution, a drive motor is mounted on the reducer, and an output end of the drive motor extends to an input end of the reducer.

[0026] Through such verticality, the drive motor can provide rotational power to the reducer.

[0027] The tray lifting mechanism of the automatic tray loading machine provided by the present invention has the following advantages:

[0028] When the present invention is started, the first pull rod moves up and down through the rotation of the cam, thereby driving the installation plate and the mobile frame to move up and down. At the same time, the cam also moves the inclined plate along the inclined guide rail through the rotating plate and the second pull rod. In addition, the lifting plate is also lifted and lowered under the action of the cam, driving the vertical plate to move, so that the reinforcement column moves horizontally. In this process, the mobile frame slides in the vertical groove of the inclined plate through the latch to ensure stability. These movements cause the plate shell to drive the storage plate to swing horizontally, and at the same time the lifting gear plate is lifted and lowered and swung, so that the upper plate operation can be smoothly performed. Through these actions, fast and efficient upper plate operation can be achieved, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] In this embodiment, by such vertical movement, the drive motor 233 can provide rotational power for the reducer 213 .

[0066] Working principle: When the automatic loading machine is started, the driving motor 233 first provides power to the reducer 213, driving the reducer 213 to drive the cam 214 to rotate. As the cam 214 rotates, the first pull rod 215 moves up and down, and this action drives the mounting plate 235, so that the mobile frame 211 generates a lifting movement. At the same time, the rotation of the cam 214 also drives the rotating plate 216 connected thereto to swing. The swing of the rotating plate 216 is transmitted to the inclined plate 224 through the second pull rod 218, so that it moves along the inclined guide rail 223. At the same time, the cam 214 cooperates with the rotation of the upper contact roller 222 to push the lifting plate 221 up and down, which in turn drives the vertical plate 230 to perform lifting and lowering movements on the vertical guide rail 220. The lifting and lowering of the vertical plate 230 causes the fixed shaft 232 in the internal inclined groove 231 to slide, thereby guiding the reinforcement column 27 to move horizontally forward and backward. During the whole process, the movable frame 211 slides in the vertical groove 229 of the inclined plate 224 through the pin 234. Through such operation, the plate shell 26 can drive the storage plate 28 to swing horizontally, and the lifting tooth plate 212 can be raised and lowered, and can swing during the lifting and lowering process, so that the lifting tooth plate 212 can drive the plate body to be put on the plate, and the storage plate 28 will avoid the position when it is put on the plate.

The replacement may be a replacement of a part of the structure, device, method step, or a complete technical solution. Any equivalent replacement or change according to the technical solution and the inventive concept of the present invention shall be covered within the protection scope of the present invention.
