[0012] The utility model is beneficial in that:
[0013] 1. The express bag packaging machine is provided with a fan (7) and a flattening device.

Therefore, the fan (7) can be used to blow out an opening in the packaging bag, and the flattening device is inserted into the packaging bag to flatten it, and then heat sealing is performed, which can ensure that the heat sealing portion is flat.
[0014] 2. In traditional express packaging machines, the feeding roller will have a certain travel error during the feeding and returning process.

Through the photoelectric sensor and system control, it can be ensured that each packaging bag has the same length after each heat seal tearing and separation. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] The flat-pull heat-sealing mechanism of an express bag packaging machine comprises a feed roller, a frame (3), a control plane (1), a heat-sealing strip (4), a fan (7) and a flattening device, wherein the feed roller is arranged in the frame (3), the express bag is conveyed by the feed roller, the control plane (1) is arranged at the front end of the frame (3), the heat-sealing strip (4) is arranged between the feed roller and the control plane (1), an upper mounting plate (6) and a lower mounting plate (5) are arranged on the frame (3) at the front end of the feed roller, the upper mounting plate (6) and the lower mounting plate are the outlets for the feed roller to convey the express bag, the fan (7) is arranged on the upper mounting plate (6), and the flattening device is arranged on the lower mounting plate (5). The flattening device comprises a draw hook (9) and a drive motor (11), the draw hook (9) is connected to the drive motor (11), and the drive motor (11) drives the draw hook (9) to rotate. The surface of the lower mounting plate (5) is provided with a first sliding groove (12) and a second sliding groove (13), the first sliding groove (12) is located above the second sliding groove (13), and the main shaft of the driving motor (11) passes through the first sliding groove (12) and is connected to the hook (9).

A transverse conveyor belt (2) is also provided below the operating platform and the feeding roller.
[0022] The actual usage is as follows:
[0023] The material roll is conveyed along with the feeding roller, and is conveyed through the photoelectric sensor. The conveying time is calculated based on the triggering time, so that the packaging bag maintains a certain tearing and separation length. Some packaging bags with static electricity are difficult to open naturally. The fan (7) set on the upper mounting plate (6) blows air to open the packaging bag. After opening, the flattening devices on both sides are started, and the draw hook (9) rotates to tighten the packaging bag to both sides, and then the hot air strip is squeezed to complete the heat sealing. After the heat sealing is completed, the feeding roller moves in the opposite direction for a certain distance to separate the heat-sealed packaging bag from the material. The separation photoelectric sensor is no longer blocked by the material, and the above steps are repeated.
[0024] Among them, the transmission of the feeding roller, the triggering conditions of the photoelectric sensor, etc., the control plane (1) controls and sets the control system, and finally determines the heat sealing process of packaging bags of different sizes.
[0025] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
