DETAILED DESCRIPTION

[0024] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.

[0025] Example 1

[0026] A food packaging bag heat sealing device, such as Figure 1-Figure 3 and Figure 5-Figure 7 As shown, it includes a control console 1, an inflation component 2, a heat sealing component 3, a cooling component 4, a conveying component 5, a fixing block 6, a pressing frame 7, a first elastic member 8, a fixing rod 9, an extrusion block 10 and a fixing plate 11. The right front part of the control console 1 is provided with an inflation component 2, the middle right front part of the control console 1 is provided with a heat sealing component 3, the heat sealing component 3 is located on the left side of the inflation component 2, and is used to heat seal the food packaging bag. The middle left front part of the control console 1 is provided with a cooling component 4, and the middle part of the control console 1 is provided with a conveying component 5. A fixed block 6 is fixedly connected to the upper right part of the front side of the console 1, and a pressing frame 7 is slidably connected to the middle part of the fixed block 6. The pressing frame 7 is used to limit the heat-sealed part of the packaging bag. A first elastic member 8 is wrapped around the upper part of the pressing frame 7, and the two ends of the first elastic member 8 are respectively connected to the fixed block 6 and the pressing frame 7. A fixing rod 9 is fixedly connected to the left side of the upper part of the pressing frame 7, and an extrusion block 10 is slidably connected to the left part of the fixed block 6. A fixed plate 11 is fixedly connected to the right part of the front side of the console 1, and the fixed plate 11 is used to limit the bottom of the heat-sealed part of the food packaging bag.

[0027] like Figure 5 As shown, the inflation component 2 includes an air pipe 201, which is arranged on the inflation component 2 and is used to inflate and evacuate the packaging bag to make the bag opening flat.

[0028] like Figure 2 and Figure 7 As shown, a handle is also included. The top of the extrusion block 10 is fixedly connected with a handle to facilitate manual pushing of the extrusion block 10.

[0029] Before the packaging bag is manually fed into the heat sealing machine, wrinkles may appear at the heat-sealed part of the packaging bag, which needs to be manually smoothed, which is troublesome. In order to solve the above problem, the present device can be used to heat-seal the packaging bag. First, the operating data of the inflation component 2, the heat sealing component 3, the cooling component 4 and the conveying component 5 are manually adjusted on the control console 1. The extrusion block 10 is manually pushed to move to the right, the extrusion fixing rod 9 is moved upward and drives the pressing frame 7 to move upward. At this time, the first elastic member 8 will be stretched. Then the packaging bag is manually held and the bag mouth of the packaging bag is moved backward to between the extrusion block 10 and the fixing plate 11, and the bag mouth of the packaging bag is wrapped around the air pipe 201 of the inflation component 2. Then the extrusion block 10 is manually pushed to reset, and then the first elastic member 8 is reset, driving the pressing frame 7 and the fixing rod 9 to reset, thereby limiting the heat-sealed part of the packaging bag, and manually controlling the inflation component 2 is used for evacuation, so that the air pipe 201 completely absorbs the air in the packaging bag, thereby making the heat-sealed part of the packaging bag flat, and then the inflation component 2 is controlled to inflate, so that the air pipe 201 fills the packaging bag with gas, and then the inflation component 2 is manually closed, and the packaging bag is manually moved to the left to enter the heat-sealing component 3. During the movement to the left, the air pipe 201 rotates and breaks away from the state of being wrapped by the packaging bag. After the heat-sealing component 3 completes the heat sealing, the packaging bag is manually released to make it contact with the conveying component 5. The packaging bag continues to move to the left, and the heat-sealed part of the packaging bag moves into the gap between the cooling component 4. While the packaging bag continues to move to the left, the heat-sealed part of the packaging bag will be cooled by the cooling component 4. The packaging bag continues to move to the left and breaks away from the contact with the cooling component 4. Then the packaging bag is manually collected and placed, thereby realizing the heat sealing of the packaging bag and ensuring that the heat-sealed part of the packaging bag is in a flat state before heat sealing.

[0030] Example 2

[0031] On the basis of Example 1, Figure 1 and Figure 4 As shown, it also includes a first cylinder 12, a first magnetic strip 13, a limiting frame 14, a second magnetic strip 15 and a second elastic member 16. The first cylinder 12 is fixedly connected to the front right side of the console 1, and the first magnetic strip 13 is fixedly connected to the left end of the first cylinder 12. The limiting frame 14 is fixedly connected to the compression frame 7, and the lower end of the limiting frame 14 is slidably connected to the second magnetic strip 15. The limiting frame 14 is used to limit the second magnetic strip 15. The first magnetic strip 13 cooperates with the second magnetic strip 15 to achieve compression and sealing of the packaging bag. The second elastic member 16 is wrapped around the right part of the second magnetic strip 15, and both ends of the second elastic member 16 are respectively connected to the second magnetic strip 15 and the limiting frame 14.

[0032] like Figure 3As shown, the first magnetic strip 13 and the second magnetic strip 15 are rubber magnets. The first magnetic strip 13 and the second magnetic strip 15 can be moved horizontally and vertically and separated better under the condition of mutual attraction.

[0033] When the heat-sealed part of the packaging tape is manually sent into the gap of the heat-sealing component 3, the bag mouth is prone to leak too much gas. When the pressing frame 7 is reset, the limiting frame 14 can be driven to move downward, and then the second magnetic strip 15 moves downward to contact the packaging bag. The second magnetic strip 15 and the first magnetic strip 13 attract each other. Due to the mutual attraction between the first magnetic strip 13 and the second magnetic strip 15, the heat-sealed part of the packaging bag is pressed. The first cylinder 12 is manually controlled to drive the first magnetic strip 13 to move and move with the second magnetic strip 15, and drive the pressed packaging bag to move. At the same time, the second elastic member 16 will be stretched. After the heat-sealed part of the packaging bag is sent into the heat-sealing component 3 for heat sealing, the bottom of the packaging bag contacts the conveying component 5, thereby reducing gas leakage. When the heat-sealing of the packaging bag is completed, the cylinder is manually controlled to drive the first magnetic strip 13 to reset. At this time, the second elastic member 16 is reset to reset the second magnetic strip 15.

[0034] It also includes a connecting frame 17, a second cylinder 18, a lower pressure plate 19 and a monitoring device 20. The connecting frame 17 is fixedly connected to the left part of the conveying component 5, the second cylinder 18 is fixedly connected to the top of the connecting frame 17, the lower pressure plate 19 is fixedly connected to the bottom of the second cylinder 18, and the monitoring device 20 is fixedly connected to the right side of the second cylinder 18. The monitoring device 20 monitors whether the food packaging bag passes by and controls the second cylinder 18 at the same time.

[0035] like Figure 4 As shown, the connecting frame 17 is made of polycarbonate, which has better impact resistance and is more suitable for some light load applications.

[0036] The packaging bag after heat sealing needs to be pressed manually to prevent air leakage caused by poor heat sealing quality of the packaging bag. When the packaging bag separates from the cooling component 4 and continues to move to the left, the monitoring device 20 senses the passing of the packaging bag and controls the second cylinder 18 to start. The telescopic rod of the second cylinder 18 moves downward and drives the lower pressure plate 19 to move to squeeze the packaging bag, thereby realizing the extrusion detection of the quality of the packaging bag after heat sealing, preventing the sale of leaking packaging bags from affecting the quality of food.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
