[0002] A heat sealer is a device that heats and closes (into a tubular shape) the packaging film of a product to achieve a sealed state. Existing heat sealers usually have two film roll installation positions, and the two film rolls alternate to achieve continuous film supply, that is, when one film roll is used up, the other film roll takes over the previous film roll to continue supplying film. When installing film rolls at the existing film roll installation positions of heat sealers, it is usually done manually, with low efficiency. Summary of the Invention

The technical solutions are as follows: The present invention proposes an automatic film loading machine, which is characterized by comprising a film storage device and a film loading device; The film storage device includes a film storage tray for placing film rolls. A film picking rod and a first film clamping mechanism are arranged on one side of the film storage tray. The film extending from the film roll passes through the film picking rod on one side and is clamped by the first film clamping mechanism; The film loading device includes a film loading bracket, on which a film hanging cross shaft, a film supporting bracket and a second film clamping mechanism are arranged. A pushing tube capable of axially moving is sleeved on the film hanging cross shaft. The film loading bracket is connected to a driving mechanism to drive the film loading bracket to move horizontally along the guide rail direction, vertically along the vertical direction of the rotating column, and rotate around the axis of the rotating column, so as to realize the horizontal, vertical movement and rotation of the film hanging cross shaft, the film supporting bracket and the second film clamping mechanism; The film roll placed on the film storage tray is concentric with the film hanging cross shaft, so that the film hanging cross shaft can be inserted into the film roll core when moving horizontally. When the film hanging cross shaft is inserted into the film roll core, the film supporting bracket extends under the film on the film picking rod. At the same time, the first film clamping mechanism releases the film, and the second film clamping mechanism clamps the film released by the first film clamping mechanism.

[0004] As a preference of the above technical solution, the driving mechanism includes a fixed sliding frame, on which a slide rail is arranged. A slide table is arranged on the slide rail. A rack is arranged on one side of the slide rail. A driving motor reducer is arranged on the slide table. A gear is arranged on the output shaft of the driving motor reducer. The gear is in transmission engagement with the rack to drive the slide table to move horizontally along the rack. A hollow turntable is arranged on the slide table. The hollow turntable is connected to the rotating column to drive the rotating column to rotate. An electric cylinder is fixed on one side of the rotating column. The electric cylinder is connected to a lifting support, and the lifting support is connected to the film loading bracket.

[0007] Preferably, as the above technical solution, the film clamping mechanism includes a film clamping bracket which has a groove, and a film clamping cylinder is arranged on one side of the groove so that when the film penetrates into the groove, the film clamping cylinder presses tightly against the film.

[0008] Preferably, as the above technical solution, there are two groups of the film storage device and the upper film device, and the two groups are used alternately.

[0009] The automatic film loading method of the automatic film loading machine includes the following steps: 1) Set the film extending from the film roll to be clamped by the first film clamping mechanism after passing through a film picking rod on one side; 2) Set the film hanging horizontal shaft to move horizontally and insert into the film roll core. When the film hanging horizontal shaft is inserted into the film roll core, the film supporting bracket penetrates under the film on the film picking rod, and at the same time, the first film clamping mechanism releases the film and the second film clamping mechanism clamps the film released by the first film clamping mechanism; 3) Set the driving mechanism to drive the film hanging horizontal shaft, the film supporting bracket, and the second film clamping mechanism to move upward to lift the film roll. At this time, the film supporting bracket supports the film on the film picking rod and the second film clamping mechanism clamps the film released by the first film clamping mechanism; 4) Set the driving mechanism to drive the film hanging horizontal shaft, the film supporting bracket, and the second film clamping mechanism to move horizontally a preset distance and then rotate to align the axis of the film roll with the film roll shaft on the heat sealer.

Then the driving mechanism drives the above components to move upward to lift the film roll, and at the same time, the film supporting bracket supports the film on the film picking rod. The driving mechanism drives the above components to move horizontally a preset distance and then rotate to align the axis of the film roll with the film roll shaft on the heat sealer. Further move horizontally closer to the heat sealer, and then the pushing pipe pushes the film roll to push the film roll onto the film roll shaft of the heat sealer. At this time, the second film clamping mechanism releases the clamped film. The above mechanism can realize the automatic film loading of the film roll and effectively improve the film loading efficiency. Brief Description of the Drawings
