[0023] The following will further describe the technical solution of the utility model in conjunction with the drawings of the embodiments of the utility model, and the utility model is not limited to the following specific implementation methods. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0024] like Figures 1 to 7 As shown, a solid stack lifting device includes: a base plate 100, a motor 200, a lifting frame assembly, a first transmission gear box 300, two first transmission shafts 400, two second transmission gear boxes 500, two second transmission shafts 600 and four lifting screw rods 700; the motor 200 is arranged on the base plate 100, and the output shaft of the motor 200 is connected to the first transmission gear box 300 through a rotating shaft, one end of the first transmission gear box 300 is connected to one of the first transmission shafts 400, and the other end is connected to another of the first transmission shafts 400, and one end of each of the first transmission shafts 400 away from the first transmission gear box 300 is connected to one of the second transmission gear boxes 500; each of the second transmission gear boxes 500 is connected to one of the second transmission shafts 600, and both ends of each of the second transmission shafts 600 are respectively connected to one of the lifting screw rods 700; the four lifting screw rods 700 are used to drive the lifting frame assembly.

[0025] Specifically, four fixing seats 110 are arranged on the base plate 100, and one end of each of the lifting screw rods 700 is rotatably arranged in one of the fixing seats 110. The lifting frame assembly includes a base frame 810 and a plurality of support frames 820, and the plurality of support frames 820 are equidistantly arranged on the base frame 810. Further, a replacement part 821 is arranged on one of the support frames 820, and the replacement part 821 is used to connect with an external stacking plate. Further, the replacement part 821 can be replaced according to the size of different stacking plates, that is, the width is adapted to the stacking plate, so as to facilitate connection with the stacking plate.

[0026] In the above embodiment, the first transmission gearbox 300 includes a first housing 310, a first gear 320 and two second gears 330, the first gear 320 and the two second gears 330 are both located in the first housing 310, the end of the rotating shaft away from the motor 200 is connected to the first gear 320, one end of each first transmission shaft 400 is connected to a second gear 330, and the first gear 320 is meshed with the two second gears 330. Each second transmission gearbox 500 includes a second housing 510, a third gear 520 and a fourth gear 530, the third gear 520 and the fourth gear 530 are both located in the second housing 510, the end of the first transmission shaft 400 away from the second gear 330 is connected to the third gear 520, the fourth gear 530 is arranged on the second transmission shaft 600, and the third gear 520 is meshed with the fourth gear 530. Two fixing plates 900 are disposed on the base frame 810, each fixing plate 900 has two through holes 910, and each fixing plate 900 has two nuts 920, that is, the nuts 920 are fixedly disposed on the fixing plates 900. Each lifting screw rod 700 passes through a through hole 910 and is slidably connected to a nut 920.

[0027] That is to say, this real stack lifting device is used in conjunction with the stack conveyor line. Since the stack conveyor line uses rollers for conveying and the stretch film machine is located at the end of the stack conveyor line, when the products and stack boards are transported to the position where the stretch film machine works, the stack conveyor line stops running. Therefore, the entire real stack lifting device is set below the position where the stretch film machine works, that is, below the stack conveyor line.

[0028] When the product and the stacking plate are moved to the film winding position, the motor 200 is started, and the output shaft of the motor 200 rotates to drive the rotating shaft to rotate, thereby rotating the first gear 320, and the rotation of the first gear 320 drives the two second gears 330 to rotate, so that the two first transmission shafts 400 also rotate. At this time, the rotation directions of the two first transmission shafts 400 are opposite. Further, due to the rotation of the two first transmission shafts 400, the two third gears 520 also rotate, and then drive the two fourth gears 530 to rotate, that is, as the fourth gear 530 rotates, the second transmission shaft 600 fixedly connected thereto also rotates. It is worth mentioning that the rotation of a second transmission shaft 600 will drive the two lifting screws 700 to rotate, and since the rotation directions of the two first transmission shafts 400 are opposite, the rotation directions of the two second transmission shafts 600 are also opposite. In order to ensure that the four lifting screws 700 can rotate at the same time to drive the four nuts 920 to rise or fall, the four lifting screws 700 can only be set on the side of the two second transmission shafts 600 close to the motor 200, that is, the two lifting screws 700 connected to a second transmission shaft 600 are both located on the side of the second transmission shaft 600 close to the motor 200. In other words, in this way, the four nuts 920 can be raised or lowered at the same time by directly driving with a motor 200.

[0029] Therefore, the two fixed plates 900 are raised by the four nuts 920, so that the entire base frame 810 drives several support frames 820 to move upward, so that the support frames 820 abut and support the entire stack plate, so that the stack plate and the product rise to the position where the winding film machine is wound, and then the product and the stack plate are wound together by starting the winding film machine. Since several support frames 820 are set, each support frame 820 passes through the stack conveyor line to rise or fall, that is, each support frame 820 moves through the gap between the two rollers. Therefore, in this way, the stack plate and the product can be wound at the same time, ensuring that there will be no deviation between the product and the stack plate. After the film is wound, the output shaft of the motor 200 is reversed, and the four lifting screw rods 700 rotate to make the four nuts 920 move downward, thereby driving several support frames 820 to move downward, and finally not abutting the stack plate, and the stack plate falls to the stack conveyor line, and then directly transported by using a forklift.

[0030] In summary, the above-mentioned implementation modes are not limitative implementation modes of the present invention, and any modification or equivalent deformation made by technicians in this field on the basis of the essential content of the present invention is within the technical scope of the present invention.
