DETAILED DESCRIPTION

[0029] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0030] Figures 1 to 8 An embodiment of the present utility model is as follows: Figures 1 to 3 As shown, a fully automatic wrapping packaging machine is used for wrapping goods, including a column 1, a film feeding mechanism 2, and a pallet 3. The column 1 is provided with a lifting mechanism, and the pallet 3 is provided with a rotating mechanism. The goods are placed on the pallet 3, and the packaging film is installed on the lifting mechanism of the column 1. The packaging machine also includes a film control mechanism 5, which is arranged on the top edge of the pallet 3.

[0031] The lifting mechanism in the column 1 includes a motor, a synchronous belt, and a synchronous pulley. A synchronous pulley is respectively arranged at the top and the bottom of the column 1. The synchronous pulley is installed on a rotating shaft. The rotating shaft is installed on the column 1 through a bearing seat. The synchronous belt connects the two synchronous pulleys, and the rotating shaft of one of the synchronous pulleys is connected to the motor.

[0032] The packaging machine further comprises a base plate 4, which is a plane frame, and the columns 1 and the tray 3 are mounted on the base plate 4. By providing the base plate 4, a unified installation reference is set for the columns 1 and the tray 3, which facilitates on-site installation.

[0033] like Figure 4 As shown, the film control mechanism 5 includes a cylinder 51, a connecting rod 52, and a film control rod 53. The cylinder body of the cylinder 51 is installed on the tray 3 through a rotating shaft. The connecting rod 52 is V-shaped, and the middle part of the connecting rod 52 is installed on the tray 3 through a rotating shaft. One end of the connecting rod 52 is hinged to the telescopic rod of the cylinder 51, and the other end is connected to the film control rod 53.

[0034] like Figure 5 , Figure 6As shown, the film control rod 53 includes a barrel 532, the barrel 532 is cylindrical, and a circle of suction cups 533 and pointed columns 534 are radially spaced on the surface of the barrel 532, and the suction cups 533 and pointed columns 534 are arranged in parallel for multiple circles; when the opening of the suction cup 533 is not subjected to pressure, the opening of the suction cup 533 is higher than the top surface of the pointed column 534, and after the opening of the suction cup 533 is deformed by pressure, the opening of the suction cup 533 is lower than the top surface of the pointed column 534. The film control rod 53 also includes a rod handle 531, one end of the rod handle 531 is connected to the barrel 532, and the other end is connected to the connecting rod 52, and the diameter of the rod handle 531 is smaller than the diameter of the barrel 532. The rod handle 531 is more convenient to replace, and the length is more convenient to increase or decrease. By setting the rod handle 531, the station position of the barrel 532 in the vertical state can be conveniently controlled.

[0035] A pallet is arranged at the bottom of the goods, and when the telescopic rod of the cylinder 1 51 is retracted, the film control rod 53 is horizontal and located below the side of the pallet; when the telescopic rod of the cylinder 1 51 is extended, the film control rod 53 is vertical and located above the side of the pallet. The packaging film is only wrapped around the goods but not the pallet.

[0036] The film control rod 53 is located at a corner of the pallet. The packaging film has a larger contact area with the film control rod 53 at the corner of the pallet. By arranging the film control rod 53 at a corner of the pallet, it is more convenient to control the feeding and breaking of the packaging film.

[0037] like Figure 7 , Figure 8 The tray 3 includes a turntable 31, a motor 32, a driving gear 33, a driven gear 34, a rotating shaft 35, and a bearing seat 36. The motor 32 is fixed on the base plate 4. The output shaft of the motor 32 is connected to the driving gear 33. The driven gear 34 is fixed to the bottom center of the turntable 31. The bottom center of the driven gear 34 is connected to the rotating shaft 35 through a flange. The rotating shaft 35 is installed in the bearing seat 36. The bearing seat 36 is installed on the base plate 4. The driven gear 34 is meshed with the driving gear 33. Through the gear transmission method, the motor 32 and the bearing seat 36 are both installed on the base plate 4, making the tray 3 compact in structure. The tray 3 can be assembled and debugged in the workshop without on-site installation and debugging, which facilitates the on-site installation of the equipment. The tray 3 also includes a universal bearing 37, which is installed on the base plate 4. The spherical ball of the universal bearing 37 fits the bottom surface of the turntable 31. A plurality of universal bearings 37 are evenly arranged around the center of the turntable 31. A slewing bearing is arranged between the rotating shaft 35 and the bearing seat 36. The slewing bearing is composed of inner and outer rings and rolling elements. It is a large bearing capable of bearing a comprehensive load and can simultaneously bear large axial and radial loads and overturning moments. The universal bearing 37 can improve the load-bearing capacity of the turntable 31.

[0038] Working principle: the extension and retraction of the telescopic rod of the cylinder 51 can drive the connecting rod 52 to rotate, thereby driving the film control rod 53 to move between the lower side and the upper side of the cargo. When the telescopic rod of the cylinder 51 is retracted, the film control rod 53 is horizontally located below the side of the cargo. When the telescopic rod of the cylinder 51 is extended, the film control rod 53 is vertically located above the side of the cargo.

[0039] By radially arranging a circle of suction cups 533 and pointed posts 534 on the surface of the cylinder 532, the automatic film feeding and film cutting of the packaging film can be realized: after the equipment is installed, one end of the packaging film is manually wrapped around the cylinder 532; when packaging goods, the telescopic rod of the cylinder 1 51 is extended, and the film control rod 53 is vertically located above the side of the goods. When the tray 3 rotates one circle, the lifting mechanism on the column 1 quickly rises to the top, and the packaging film is wrapped around the goods and adheres to the goods; the telescopic rod of the control cylinder 1 51 is retracted, and the film control rod 53 falls to a horizontal state, and the packaging film is detached from the film control rod 53. Continue to complete the wrapping packaging of the goods. After the goods are packaged, the telescopic rod of the control cylinder 1 51 is extended, and the film control rod 53 rotates to a vertical state. When the control tray 3 rotates one circle, the lifting mechanism on the column 1 quickly drops to the bottom, and the packaging film wraps around the film control rod 53, and the suction cup 533 absorbs the packaging film, and the packaging film is attached to the cylinder 532. At this time, the goods are removed, and the packaging film exerts a pulling force on the film control rod 53, pressing down the opening of the suction cup 533, so that the pointed column 534 is higher than the opening of the suction cup 533, and the top of the pointed column 534 pierces the packaging film, completing the cutting of the packaging film, and the packaging film is separated from the goods, and the packaging film is still adsorbed on the suction cup 533. The wrapping packaging machine has a simple structure, and can realize automatic film feeding and film cutting of the packaging film, thereby improving production efficiency with minimal cost.

[0040] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
