[0039] Connecting blocks 8 are installed on both sides of the lifting platform 5, the connecting blocks 8 are threadedly connected with the support threaded columns 4, and the connecting blocks 8 are slidably connected with the inner wall of the mounting groove 3. When the two support threaded columns 4 rotate, they will drive the two connecting blocks 8 to move upward. By setting the two support threaded columns 4, the supporting ability of the lifting platform 5 is greatly enhanced.

[0040] The rotating mechanism includes a load - bearing platform 9 and a load - bearing groove 10. The load - bearing groove 10 is opened at the bottom of the gantry 2, the bottom of the load - bearing platform 9 is located inside the load - bearing groove 10, and the load - bearing platform 9 is movably connected with the load - bearing groove 10. A toothed ring 11 is installed on the surface of the load - bearing platform 9, a rotating motor 12 is installed on one side of the base 1, a gear 13 is installed at the output end of the rotating motor 12, and the said gear 13 meshes with the toothed ring 11.

[0041] A load - bearing plate 14 is fixed on the load - bearing platform 9, a tray 15 is placed on the load - bearing plate 14, and a limiting mechanism is arranged on the tray 15.

[0042] 19. First clamping blocks 17 are fixed on both sides of the tray 15, a clamping groove 19 is opened on the first clamping block 17, and the baffle

[0043] 16. A second clamping block 18 is fixed at the bottom of the baffle 16, and the baffle 16 is installed on the clamping groove 19 through the first clamping block 17.

[0044] An L-shaped plate 20 is fixed under the lifting platform 5, and a placement groove 21 is opened on the surface of the L-shaped plate 20. A push plate 22 is slidably arranged inside the placement groove 21. A top column 23 is fixed on one side of the push plate 22.

At this time, the staff member toggles 22 to drive the top column 23 to move so that the top column 23 is disengaged from the baffle 16. At this time, the baffle 16 can be easily removed by holding the handle 26.

[0046] The winding mechanism includes a pre-stretching winding device 27 and a support rod 28 fixed at intervals on one side of the lifting platform 5. The pre-stretching winding device 27 includes a pre-stretching film frame and a winding film. Since they are all prior arts, they are not described in detail here. The surface of the support rod 28 is provided with a slide groove 29. The two sides of the pre-stretching winding device 27 are respectively connected to the two slide grooves 29 for sliding. Two first vertical plates 30 are fixed at intervals on the surface of the lifting platform 5. A rotating shaft 31 is provided between the two first vertical plates 30 through a bearing. An I-shaped winding A wire drum 32, a pull rope 33 is provided on the I-shaped wire drum 32, a limit shaft 34 is fixed between the two support rods 28, two limit plates 35 are fixed on the limit shaft 34 at intervals, a lifting ring 36 is installed on the top of the pre-stretching winder 27, one end of the pull rope 33 is fixed on the lifting ring 36, and the pull rope 33 is located between the two limit plates 35. When the height of the stacked goods increases, the second drive motor 45 can be turned on to move the pre-stretching winder 27 downward, and when the height of the stacked goods decreases, the pre-stretching winder 27 can be moved upward.

[0047] One end of the rotating shaft 31 passes through the first vertical plate 30 and is installed with a worm gear 37. Two second vertical plates 38 are arranged at intervals on one side of the worm gear 37. The second vertical plates 38 are fixed to the surface of the lifting platform 5, and a worm 39 is movably arranged between the two second vertical plates 38 through a bearing. The worm 39 and the worm gear 37 are meshed with each other. Since the worm 39 and the worm gear 37 have a self-locking function, when the first driving motor 40 stops rotating, the pre-stretching winder 27 stops in place.

[0048] A first drive motor 40 is installed on the lifting platform 5, and the output end of the first drive motor 40 is connected to the worm 39 through a coupling. The tops of the two supporting threaded columns 4 both penetrate the gantry 2 and are installed with a first bevel gear 41. A stand 42 is fixed on the top of the gantry 2, and a transmission shaft 43 is inserted on the stand 42. Two second bevel gears 44 are installed on the transmission shaft 43 at intervals, and the two second bevel gears 44 are respectively meshed with the two first bevel gears 41. A second drive motor 45 is installed on one side of the gantry 2, and the second drive motor 45 is connected to the transmission shaft 43 through a coupling. Turning on the second drive motor 45 can make the two supporting threaded columns 4 rotate at the same time, driving the lifting platform 5 to move downward, and compacting the goods through the cylinder 6 on the lifting platform 5. While greatly reducing the footprint of the equipment, the present invention also ensures the supporting capacity through the two threaded columns 4, and can withstand the reaction force of the cylinder 6 when compacting the goods.

[0049] Working principle of the present invention: When the wrapping machine is used, a person skilled in the art can first insert the bottom of the baffle 16 into the card slot 19 in the loading area, and then stack the nylon bags packed with talcum powder on the tray 15. Under the action of the two baffles 16, the staff can be prevented from stacking the nylon bags at an excessive tilt, which will affect the cylinder 6 to flatten them later;

[0050] When the goods are stacked, the staff can use a forklift to transport the pallet 15 to the load-bearing plate 14. At this time, since the goods will be squeezed to both sides, it is difficult to take out the baffle 22 by manpower alone. Therefore, the staff can turn on the second drive motor 45 to drive the transmission shaft 43 to rotate. Driven by the transmission shaft 43, the two second bevel gears 44 rotate at the same time, driving the two first bevel gears 41 to rotate synchronously, so that the lifting platform 5 will move up and down along the mounting groove 3. When the lifting platform 5 moves down, the L-shaped plate 20 also moves down. When the top column 23 on the L-shaped plate 20 contacts the arc surface on the baffle 16, the top column 23 will shrink and drive the push plate 22 to move until the top column 23 enters the inside of the positioning hole 25. The top column 23 can be reset under the action of the reset spring 24, and the second drive motor 45 is turned on to drive the lifting platform 5 to move upward, so that the top column 23 drives the baffle 16 to move upward until the second block 18 at the bottom of the baffle 16 Disengage from the card slot 19, and then the staff member turns 22 to drive the top column 23 to move so that the top column 23 is separated from the baffle 16, and then the baffle 16 can be easily removed;

[0051] When it is necessary to press down the goods, start the second drive motor 45 to drive the lifting platform 5 to move above the goods. At this time, open the air cylinder 6 to drive the pressing plate 7 to move, and then the goods can be pressed, which is convenient for winding and transporting. When the goods are pressed, start the air cylinder 6 to reset the pressing plate 7. At this time, open the rotating motor 12. Under the action of the gear 13 and the toothed ring 11, the goods rotate, and the film on the pre-stretching winder 27 winds the goods. During the winding process, when the second drive motor 45 starts to reset the lifting platform 5, it also drives the pre-stretching winder 27 to move upward, so as to complete the all-round winding of the goods. There is no need for an additional lifting device to lift the pre-stretching winder 27. After the winding is completed, the operator cuts the winding film with tools, and then the forklift can take away the goods.

[0052] Since the stacking heights of different batches of goods on the pallet 15 are different, those skilled in the art can pre-adjust the distance between the pre-stretching winder 27 and the lifting platform 5 according to the stacking height of different batches of goods, so that while the pressing plate 7 can press the goods, the bottom of the pre-stretching winder 27 is flush with the bottom of the pallet 15, ensuring that the film can wind around the goods all-round. The specific operation is to open the first drive motor 40. Under the transmission of the worm gear 37 and the worm 39, the I-shaped winding disc 32 rotates, driving the pulling rope 33 to move, and then the pre-stretching winder 27 moves vertically along the chute 29.

[0053] The circuits and controls involved in the present invention are all prior arts and will not be elaborated here.

[0054] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present invention.
