[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figure 1-3 The shown pressing device for a bag making machine includes a pillar 1 and a fixed plate 2, a conveying mechanism 3 is rotatably connected between the two fixed plates 2, the conveying mechanism includes a rotating roller and a conveyor belt, which drives the plastic bags to move, a support frame is fixedly connected to the upper side of the fixed plate 2 and an electric push rod 4 is fixedly connected to the bottom side of the support frame, a pressing plate 5 is fixedly connected to the bottom end of the electric push rod 4, the electric push rod 4 drives the pressing plate 5 to move up and down and press the plastic bags, the pressing plate 5 is connected to an external power supply 6 through a wire, the external power supply 6 is used to supply heat to the pressing plate 5, the external power supply 6 is fixedly connected to the support frame, a first groove 7 is opened on the support frame, and support plates 8 are fixedly connected to the support frame on both sides of the first groove 7, one of the support plates 8 is fixedly connected to a driving motor and a screw 9 is fixedly connected to the output end of the driving motor, a scraper 10 is threadedly connected to the screw 9, the driving motor drives the screw 9 to rotate and causes the scraper 10 to move back and forth.

[0018] The support frame is fixedly connected to a display 12, which is connected to an infrared sensor 11 via a wire. The infrared sensor 11 is fixedly connected to two sides of the scraper 10 that are far away from each other. By setting the infrared sensor 11, it is possible to monitor whether the scraper 10 is adhered to material.

[0019] The support plate 8 is in contact with the ball 13 , and the ball 13 is rotatably embedded in the infrared sensor 11 . The arrangement of the ball 13 reduces the friction between the infrared sensor 11 and the support plate 8 when the infrared sensor 11 moves.

[0020] Among them, the scraper 10 corresponds to the cleaning plate 14, the cleaning plate 14 is fixedly connected to one side of the rotating rod 15, the rotating rod 15 is rotatably connected to the support plate 8, and the support plate 8 is an L-shaped structure.

[0022] Working principle: when the plastic bag moves to the bottom side of the pressing plate 5 on the conveying mechanism 3, the pressing plate 5 maintains heat under the state of the external power supply 6. At this time, the electric push rod 4 drives the pressing plate 5 to move downward and contact the plastic bag for pressing. Then, after the pressing is completed, the bottom side of the pressing plate 5 contacts the upper side of the first groove 7, and the driving motor is started to drive the screw 9 to rotate, and the scraper 10 moves on the bottom side of the pressing plate 5, and cleans the pressing plate 5. At the same time, the infrared sensor 11 is used to monitor the state of the scraper 10. When it is detected that there is material stuck on the scraper 10, the scraper 10 is moved to contact the cleaning plate 14, and the cleaning plate 14 is rotated under force. The contact point between the cleaning plate 14 and the scraper 10 gradually moves upward and removes the plastic stuck on the scraper 10.
