As an improvement of the invention, the upper end face of the rack is provided with a guide rail wheel track, and the prefabricated bag bin is in sliding connection with the guide rail wheel track through a guide rail wheel at the bottom of the prefabricated bag bin.
As an improvement of the invention, the prefabricated bag bin is also connected with a power mechanism, and the power mechanism can drive the prefabricated bag bin to slide on the track of the guide rail wheel.
As an improvement of the invention, the power mechanism comprises a servo motor and a synchronous belt, the synchronous belt is connected with the bottom of the prefabricated bag bin, and one end of the synchronous belt is connected with the servo motor.
As an improvement of the invention, the other end of the synchronous belt is connected with a horizontal sliding block, the horizontal sliding block is connected on the rack in a sliding manner through a guide rail, and the horizontal sliding block can slide on the upper end of the rack in a straight line manner.
As a modification of the invention, the number of the prefabricated bag bins is two.
As an improvement of the invention, the bag opening mechanism comprises a bag opening cylinder and a bag opening plate, the bag opening cylinder is fixed on the packaging frame, and the bag opening plate is connected with a piston of the bag opening cylinder.
Has the advantages that:
the invention can carry out prefabricated bag packaging and film packaging on the same set of equipment, has simple and reasonable structure, and effectively overcomes the defect that the traditional packaging machine can only meet one packaging type, thereby greatly reducing the production cost and meeting the diversity requirements of the market.

Detailed Description
Embodiments of the present invention are further described below with reference to the accompanying drawings.
The first embodiment is as follows:
as shown in fig. 1 to 3, the universal pre-bag and sheet film packaging machine in the present embodiment includes a frame 1, a sealing mechanism, and a packaging mechanism; the packaging mechanism comprises a packaging frame 2 fixed on the rack 1, a feeding port base plate 3 for guiding materials into the packaging frame 2 is arranged at the front end of the packaging frame 2, a bag suction head 5 is arranged at the upper end of the packaging frame 2 through a driving device 4, and a bag opening mechanism 6 and a material supporting chain roller group 7 are further arranged in the packaging frame 2.
In this embodiment, two prefabricated bag bins 8 are arranged between the packaging mechanisms of the frame 1, a guide rail wheel track 9 is arranged on the upper end face of the frame 1, the prefabricated bag bins 8 are slidably connected with the guide rail wheel track 9 through guide rail wheels at the bottoms of the prefabricated bag bins 8, the prefabricated bag bins 8 are further connected with a power mechanism 10, and the power mechanism 10 can drive the prefabricated bag bins 8 to slide on the guide rail wheel track 9; the power mechanism 10 comprises a servo motor 101 and a synchronous belt 102, the synchronous belt 102 is connected with the bottom of the bag pre-making bin 8, one end of the synchronous belt 102 is connected with the servo motor 101, the other end of the synchronous belt 102 is connected with a horizontal sliding block 103, the horizontal sliding block 103 is connected to the rack 1 in a sliding mode through a guide rail, the horizontal sliding block 103 can slide linearly on the upper end of the rack 1, and in the transmission process, the horizontal sliding block 103 plays a role in improving transmission stability and accuracy; the bag opening mechanism 6 comprises a bag opening cylinder and a bag opening plate, the bag opening cylinder is fixed on the packaging frame 2, and the bag opening plate is connected with a piston of the bag opening cylinder.
In the embodiment, when the invention works, the prefabricated bags are placed on the prefabricated bag bins 8, one prefabricated bag bin 8 is moved to the lower end of the packaging mechanism through the power mechanism 10, the material supporting chain rollers 7 comprise driving rollers, in the initial state, the driving roller moves the material supporting frame to a vertical surface so as to make room for taking and opening the bag, the driving device 4 controls the suction bag suction head 5 to move downwards to suck the upper surface of the uppermost bag of the prefabricated bag bin 8, then the driving device 4 controls the suction bag suction head 5 to move upwards, so that the prefabricated bag sucked by the upper end is automatically opened under the action of self gravity, at the moment, the bag opening cylinder of the bag opening mechanism 6 inserts the bag opening plate into the opened bag to play a bag opening role, meanwhile, the material supporting frame of the material supporting chain roller group 7 moves to a position between the sucked bag and the bag on the prefabricated bag bin 8, and the functions of separation and material supporting are achieved; then the material is pushed into the expanded prefabricated bag by external equipment through the feeding port base plate 3, and then is continuously pushed out of the sealing mechanism to be sealed, so that one-time packaging is completed. When the bag on the prefabricated bag bin 8 at the lower end of the packaging mechanism is used up, the power mechanism 10 controls the other prefabricated bag bin 8 filled with the bag to move to the lower end of the packaging mechanism, the prefabricated bag bin 8 without the bag is moved out of the packaging mechanism, and the prefabricated bag bin 8 is manually fed.
Example two:
as shown in fig. 4, in the present embodiment, an existing film bag former assembly is provided between the frame 1 and the packaging mechanism, instead of the prefabricated bag magazine 8. The material is pushed into the film bag-shaped former assembly by external equipment through the feeding port base plate 3, and film packaging is completed.
