The cold air blower in this patent blows cold air to the sealing area through a duct and a gooseneck tube to cool the sealing area and make the seal solidify quickly to prevent the seal from bursting. However, it also has the following defects: the packaging bag in this patent needs to be manually placed into the sealing device, and only one bag can be sealed at a time, which leads to the need to improve the processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a fully automatic film sealing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic film sealing device, comprising a material conveyor belt and a fixed box. The fixed box is provided with two metal conveyor belts that drive each other on one side near the material conveyor belt. One end of the film is conveyed between the two metal conveyor belts. Each of the two metal conveyor belts is provided with a relatively movable pressure block. Each pressure block is provided with an electric heating component. A guide component is provided above the material conveyor belt. The guide component includes a U-shaped plate. Both sides of the bottom end of the U-shaped plate are fixedly connected with blocking strips. A push plate is movably arranged between the two blocking strips.

[0006] In a preferred embodiment, the material conveyor belt is mounted on a conveyor frame, a bracket is fixedly connected to one side of the conveyor frame, an electric push rod is fixedly connected to the top of the bracket, the telescopic end of the bottom of the electric push rod is fixedly connected to the top of the U-shaped plate, and the U-shaped opening of the U-shaped plate is oriented downwards.

[0007] In a preferred embodiment, an auxiliary frame is fixedly connected to the end of the U-shaped plate away from the fixed box, and the auxiliary frame is positioned above the two blocking strips; The auxiliary frame is rotatably connected to a lead screw, and a moving block is threaded onto the outer side of the lead screw. The push plate is fixedly connected to the bottom end of the moving block.

[0008] In a preferred embodiment, a servo motor is fixedly connected to one end of the auxiliary frame, and the drive shaft of the servo motor is fixedly connected to one end of the lead screw.

[0009] In one preferred embodiment, a plurality of rotating drums are rotatably connected to one side of the fixed box, and two metal conveyor belts are drivenly connected to the corresponding rotating drums. The two metal conveyor belts are distributed vertically, and the opposite sides of the two metal conveyor belts are in contact with each other.

[0010] In a preferred embodiment, each of the two metal conveyor belts is provided with a fixing plate, which is fixed in a fixing box. A cylinder is fixedly connected to one side of each of the two fixing plates. The opposite side of each of the two cylinders is fixedly connected to a corresponding pressure block, and the pressure block is located inside the corresponding metal conveyor belt. One end of each of the two metal conveyor belts is provided with a belt-removing belt, and the gap between the two belt-removing belts corresponds to the gap between the two metal conveyor belts.

[0011] In a preferred embodiment, a cooling fan is fixedly connected inside the fixed box. The cooling fan is positioned between the belt conveyor and the metal conveyor belt, and the air outlet of the cooling fan faces the conveyor frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This fully automatic film sealing device uses a guide assembly consisting of an electric push rod, a blocking bar, a lead screw, a push plate, and a servo motor. After the infrared sensor detects the packaging bag, the electric push rod drives the blocking bar to descend and initially limit the packaging bag. The friction of the material conveyor belt is used to automatically correct the packaging bag. Then, the servo motor drives the lead screw to push the push plate to accurately push the packaging bag between the metal conveyor belts. This effectively avoids the problem of skewed sealing caused by packaging bag deviation, ensures that the sealing position of all packaging bags is consistent, and improves the aesthetics and standardization of the finished packaging.

[0013] This fully automatic film sealing device uses a cylinder to drive the pressure block to achieve pressing, and the pressure output is stable, which can ensure uniform force at the sealing point. The electric heating component is equipped with a ceramic insulating heat-conducting layer on the outside, which can achieve efficient heat transfer and avoid the risk of leakage.

[0014] This fully automatic film sealing device achieves fully automated control of the entire process of packaging bag detection, positioning, pushing, sealing, cooling and discharging through infrared sensors and PLC controllers. It requires no manual operation, which not only reduces labor input and lowers labor costs in the production process, but also avoids the impact of human operation errors on sealing quality. At the same time, the fully automated operation increases the number of seals per unit time, significantly improving production efficiency, and is suitable for mass packaging production scenarios.

[0015] This fully automatic film sealing device has a cooling fan installed between the metal conveyor belt and the belt-off belt. This fan can instantly cool the sealed packaging bags, accelerate film curing, and prevent deformation of the high-temperature sealed area due to contact during subsequent transportation, thus further ensuring sealing quality. At the same time, rapid cooling shortens the curing time after sealing, allowing the packaging bags to quickly enter the subsequent collection process, improving production continuity and reducing waiting time between processes.

In this embodiment, a lead screw 8 is rotatably connected to the auxiliary frame 9 via a bearing seat. A moving block 10 is threadedly fitted to the outside of the lead screw 8. A push plate 11 is welded to the bottom of the moving block 10. The push plate 11 is slidably disposed between two blocking bars 7. A servo motor 12 is fixedly connected to one end of the auxiliary frame 9 via bolts. The drive shaft of the servo motor 12 is fixedly connected to one end of the lead screw 8 via a coupling.

[0022] Multiple rotating drums are rotatably connected to one side of the fixed box 2. Two metal conveyor belts 14 are driven and connected to the corresponding rotating drums. The two metal conveyor belts 14 are distributed vertically, and the two metal conveyor belts 14 are in contact with each other on opposite sides.

[0023] Please see Figure 3 and Figure 4 Multiple rotating drums are divided into upper and lower groups. Each group of rotating drums is connected to a metal conveyor belt 14. The two metal conveyor belts 14 are distributed opposite each other, and their opposite sides are attached to each other to form a conveying channel for clamping the sealing end of the packaging bag.

[0024] In this embodiment, the infrared sensor, electric push rod 4, and servo motor 12 are all electrically connected through a controller. The controller adopts a PLC control system, which can realize the coordinated operation of each mechanism. This is a publicly available technical means. The specific electrical connection method (circuit layout) and control method will not be described in detail here. When the infrared sensor detects the packaging bag passing by, it transmits a signal to the controller. The controller controls the electric push rod 4 to start, driving the guide component 5 to descend and position the packaging bag.

[0025] Please see Figure 4 Each of the two metal conveyor belts 14 has a fixing plate 17 inside, which is fixed in the fixing box 2.

[0028] Working principle: The packaging bag to be sealed is placed on the material conveyor belt 1. The infrared sensor at the bottom of the bracket 3 can detect the material passing by. Then, the electric push rod 4 drives the two blocking bars 7 to descend and block the passing packaging bag, placing it between the two blocking bars 7. As the material conveyor belt 1 continues to move, the friction force can make the packaging bag contact one side of the blocking bar 7, making the packaging bag position upright. Then, the servo motor 12 is started, causing the push plate 11 to move the packaging bag towards the fixed box 2, so that one end of the packaging bag can be guided between the two metal conveyor belts 14.

[0029] As the packaging bag enters between the two metal conveyor belts 14, it moves with the relative rotation of the metal conveyor belts 14. When it reaches the position of the pressing block 15, the two cylinders 16 and the electric heating rod are activated, which drives the two heated pressing blocks 15 to move relative to each other and act on the metal conveyor belt 14. The heat and pressure are transferred to the edge of the packaging bag through the metal conveyor belt 14 to complete the automatic sealing work. Then it is cooled by the cooling fan 13 and then carried out by the belt 18.
