[0021] like Figure 1 and Figure 3As shown, an automatic lifting mechanism of a packaging machine includes: a base plate 100, a base plate waist-shaped groove 200, a motor 300, a bevel gear 400, a transmission rod 500, a screw rod 600, a slider 700, a lifting plate 800 and a guide structure 900. The base plate waist-shaped groove 200 is symmetrically arranged in the middle of the base plate 100, the motor 300 is arranged at the bottom of the base plate 100, the shaft end of the motor 300 passes through the base plate 100, the shaft end of the motor 300, the transmission rod 500 and the screw rod 600 are provided with bevel gear 400, the motor 300 and the transmission rod 500 are connected by the bevel gear 400, the transmission rod 500 and the screw rod 600 are connected by the bevel gear 400, the screw rod 600 is symmetrically fixed on both sides of the base plate 100, the slider 700 is arranged on the screw rod 600, the slider 700 is connected to the lifting plate 800, the bottom of the lifting plate 800 is connected to the guide structure 900, and the guide structure 900 is arranged in the base plate waist-shaped groove 200;

[0022] like Figure 4 As shown, the guide structure 900 includes: a rolling bearing 910, a movable plate 920, a plane bearing 930 and a stud bolt 940, the rolling bearing 910 and the plane bearing 930 are connected to the movable plate 920, the rolling bearing 910 is connected to the waist-shaped groove 200 of the substrate, and the plane bearing 930 is connected to the lifting plate 800 through the stud bolt 940.

[0023] like Figure 2 As shown, the bevel gear 400 includes: a first bevel gear 410, a second bevel gear 420, a third bevel gear 430 and a fourth bevel gear 440, the first bevel gear 410 is connected to the shaft end of the motor 300, the second bevel gear 420 is arranged at both ends of the transmission rod 500, the third bevel gear 430 is arranged on the transmission rod 500, the third bevel gear 430 is arranged behind the second bevel gear 420, the fourth bevel gear 440 is connected to the top end of the screw rod 600, the first bevel gear 410 is connected to the second bevel gear 420, and the third bevel gear 430 is connected to the fourth bevel gear 440.

[0024] The principle of the utility model is: the motor 300 drives the transmission rod 500 to perform horizontal rotation through the cooperation of the first bevel gear 410 and the second bevel gear 420. The bottom of the screw rod 600 on both sides is equipped with the fourth bevel gear 440 and the third bevel gear 430 of the transmission rod 500, so that the screw rod 600 is transmitted, so that the slider 700 located on the screw rod 600 moves up and down. The lifting plate 800 and the slider 700 are fixed by side bolts. The guidance of the lifting plate 800 is realized by the substrate waist groove 200 on the substrate 100 to achieve up and down movement. The lifting plate 800 is close to the substrate 100, and is fixed by the plane bearing 930 between the moving plate 920 and the lifting plate 800 to move up and down in a fitting manner. Two plane bearings are installed at both ends of the moving plate and the lifting plate, and the plane bearing on the moving plate is close to the inner side of the substrate, and the plane bearing on the lifting plate is close to the outer side of the substrate. The lifting plate and the moving plate are connected by bearings and stud bolts. The two rolling bearings 910 on the moving plate 920 are rotated and guided up and down in the waist-shaped groove 200 of the substrate.

[0025] The utility model optimizes the traditional guide shaft structure and achieves both compact structure and stable transmission by adding a guide structure 900.

[0026] On the one hand, the structure of the guide shaft occupies a large volume and is installed on the outside of the whole, while the guide structure 900 of the utility model is in close contact with the lifting plate 800 and is located below the base plate. The principle is to realize a new transmission linkage by opening a waist-shaped groove 200 in the base plate. The utilization rate of space is improved by the new connection relationship. On the other hand, the utility model effectively improves the offset problem during the lifting process. The problem occurs because the traditional guide shaft is unevenly stressed during the transmission process, and the phenomenon manifested is various offsets. If you want to correct and solve the offset phenomenon during the movement process, you must avoid the offset problem.

[0027] Therefore, the utility model first needs to limit the position, and the transmission of the entire guide structure 900 is limited in the waist-shaped groove 200 of the substrate, and can only be lifted and lowered forward and backward. Secondly, to make longitudinal corrections, a rolling bearing 910 is used for guiding movement. The rolling bearing 910 slides directly in the waist-shaped groove 200 of the substrate, transmits the motion trajectory to the moving plate 920, and then transmits it to the lifting plate 800, thereby preventing left and right deviation. Finally, a plane bearing 930 is used in conjunction with a stud bolt 940 to directly establish a transmission relationship with the lifting plate 800, thereby preventing forward and backward shaking.

[0028] Compared with the traditional technology, the utility model uses a combination of a waist-shaped groove of the base plate and a guide structure, which, on the one hand, replaces the traditional guide shaft to make the entire structure more compact and reduce the occupied space; on the other hand, through the limit, the moving plate will not be offset during the lifting process.

[0029] The specific implementation modes of the present invention are described above, but the present invention is not limited thereto. The present invention can also have various changes without departing from the purpose of the present invention.
