After the product is loaded into the packaging container, in order to seal and preserve the product, maintain the product quality, and avoid product loss, it is necessary to seal the packaging container. The heat sealing process is as follows: heating to melt the plastic film so as to form a sealed joint surface at the sealing position; compacting and cooling the heated plastic film with the packaging material. After retrieval, Chinese Patent CN219487905U discloses a heat seal bag heat seal clamping assembly, including a base, a main control box, and a first support frame. A main control box is fixedly installed on the top of the base, a first support frame is fixedly connected to the top of the base, a control panel connected to the input end of the main control box is fixedly installed on the top of the first support frame, a first side plate is fixedly connected to the top of the base, a cross plate is fixedly installed on one side of the first side plate, a support column is slidably installed through the inside of the cross plate, a second support frame is fixedly installed on the top of the support column, a second side plate is fixedly connected to the top of the second support frame, a transmission track is rotatably connected between the second side plates through a gear, a servo motor is fixedly installed at the front end of the second side plate, a heat seal main body is fixedly installed at the front end of the first support frame, a first electric telescopic rod is fixedly installed inside the heat seal main body, one end of the first electric telescopic rod is fixedly connected to a preheating block, a third electric telescopic rod is fixedly installed inside the heat seal main body, and one end of the third electric telescopic rod is fixedly connected to a heat seal block.

[0003] The deficiencies of the above patent are as follows: First, after the heat sealing treatment of the bag is completed, the cooling fan blows air through the wire mesh to cool down the heat seal bag, with many operation steps and low heat seal cooling efficiency; second, after heat sealing and then cooling, because the sealing temperature is high, it is easy to cause the sealing to be wrinkled and uneven, affecting the sealing effect. After heat sealing and then cooling, without pressing or flattening, it causes the sealing to shrink further, the sealing is more wrinkled and uneven, and there may be no sealing at a certain part of the sealing, resulting in poor sealing effect; third, in the above patent, the sealing needs to be preheated by the preheating block of the first electric telescopic rod, extruded by the pressing plate of the second electric telescopic rod, and finally hot pressed by the hot air block of the third electric telescopic rod. The hot pressing process is complex, with many electric telescopic rods used, high usage cost, and the whole process is cumbersome, the operation is complex, greatly prolonging the hot pressing time and reducing the sealing efficiency; fourth, after the heat seal bag is hot pressed, the high temperature may cause the bag mouth of the heat seal bag to adhere to the hot pressing block, which requires manual cleaning, reducing the sealing efficiency; fifth, the above patent can only heat seal one heat seal bag at a time, with low heat seal efficiency.

[0090] Six embodiments are given above, which can be set according to requirements. The difference between Embodiment 1 and Embodiment 2 lies in whether a groove 5 is provided on the heat dissipation support member 1. The heat dissipation support member 1 includes a heat dissipation part and a support part fixedly connected. The support part is in the shape of a side plate. A groove 5 is provided on one side of the support part to facilitate the installation and support of the heating member 2. Heat dissipation holes are provided on the other side of the support part, and the heat dissipation holes are provided on the heat dissipation part to form a heat dissipation channel 4, that is, the heat dissipation channel 4 and the heating member 2 are separated by the support part. The support part can be made relatively thin and can support the heating member 2. The support part is heat-conductive, which enables the wind to directly dissipate heat from the heating member 2 and the heat-sealed mouth after passing through the heat dissipation channel 4, with fast heat dissipation speed and high efficiency.

[0091] In Embodiment 1 and Embodiment 2, the existing insulating material, such as plastic, is selected for the heat dissipation support member 1 to avoid interference with the heating member 2. In Embodiments 3 - 6, the heat dissipation support member 1 can be made of insulating material or metal material, such as aluminum material. The heat dissipation support member 1 and the heating member 2 are separated by an insulating heat-conducting sheet 6 or an insulating heat-conducting coating to protect the heating member 2 and also facilitate the replacement of the heating member 2. An anti-sticking sheet 7 or an anti-sticking coating can be provided on the other side of the heating member 2 to prevent the seal of the heat-sealed bag from adhering to the heating member 2 during use, further extending the service life of the heating member 2 and reducing the heat-sealing cost.

[0092] Before use, the hot pressing device 9 with rapid cooling is installed on the frame 8 of the sealing machine. The heat dissipation support member 8 is connected to the frame 8 through a driving member 11 and is driven by the driving member 11. The hot pressing device 9 with rapid cooling is arranged corresponding to the pressing plate 10. The heating member 2 is fixedly connected to the support part of the heat dissipation support member 1 to form a heating and extrusion end face. The support part supports the heating member to heat and extrude the seal. The pressing plate 10 is a pressing surface that cooperates with the heating and extrusion end face. The pressing plate 10 can also be driven by a driving member. The driving member is such as a driving cylinder, and the driving cylinder can be a pneumatic cylinder, an electric cylinder or a hydraulic cylinder, which can be set according to requirements. A control system can be provided on the frame 8. The control system is such as a PLC control system. The driving member 11, the heating member 2 and the blowing driver 3 are controlled through the control system to realize automatic hot pressing. An elastic plate 17, such as rubber, which is elastic, can be provided on the pressing plate 10 to ensure reliable extrusion. A reliable pressing mechanism 12 is also provided on the pressing plate 10. Guided by a guide rod 14 and pressed by a pressing spring 15, the pressing plate 10 is tightly and reliably pressed against the heating member 2. When the pressing frame 13 is relatively long, the pressing frame 15 and the frame 8 can be guided and slid through a slideway and a slide rail to better complete the heat-sealing operation.

[0093] During use, the heat-sealing bag can be placed between the conveyor belt, or the robot, or manually placed between the heating component 2 and the pressing plate 10. The control system drives the driving component 11, and the heating and extrusion end face approaches and presses the sealing part of the heat-sealing bag to be heat-sealed with the pressing surface. The control system starts the heating component 2, and the heating component 2 is powered on to generate instant high temperature for heating. After a certain period of time, the control system starts the blowing driver 3. The blowing driver 3 is a fan, and the air blows from the heat dissipation channel 4 from top to bottom, directly cooling the heating component 2 and the sealing part of the heat-sealing bag. After a certain period of time, the blowing driver 3 and the heating component 2 are turned off, and the driving component 11 drives the heating and extrusion end face and the pressing surface to separate, completing the hot pressing of the heat-sealing bag.

[0094] The utility model can cool down while hot pressing, realize sealing through hot pressing, and cool down while hot pressing, which can make the seal flat and without wrinkles. The operation is simple, the steps are few, the heat-sealing efficiency is high, the use cost is low, and the sealing efficiency is improved. Moreover, by setting the insulating heat-conducting sheet 6 or the insulating heat-conducting coating, the utility model can not only protect the heating component 2, but also isolate the heat dissipation support component 1 and the heating component 2, further extending the service life of the sealing machine. The utility model also sets the anti-sticking sheet 7 or the anti-sticking coating on the heating component 2, which can prevent the seal from adhering to the heating component 2 after heat-sealing, protecting the heating component 2 while improving the heat-sealing efficiency. In addition, multiple hot pressing devices 9 with rapid cooling can be arranged on one side of the frame 8 of the utility model, and the pressing plate 10 cooperating with them is arranged opposite to the hot pressing devices 9 with rapid cooling, and multiple plastic-sealed bags can be heat-sealed at one time, with high efficiency.

[0095] Due to the adoption of the above structure, the utility model has the advantages of ingenious structure, fast heat dissipation speed during sealing, high efficiency, flat seal, reliable seal pressing, and low use cost.
