Description

Technical Field

[0001] The present invention relates to the field of heat-sealing devices, and specifically to a heat-sealing device for packaging bags. Background Art

[0002] Thermal compression sealing is a technique of heating the material at the sealing part in a certain way to make it reach the viscous flow state and then applying pressure to make it stick and seal. A heat-sealing device for packaging bags is a device used to seal packaging bags, mainly used to seal the opening part of the packaging bag by heating and pressing to prevent the contents from leaking. Such devices are widely used in industries such as food, medicine, and daily chemicals. Usually, the packaging bag to be sealed is placed in the working area at the heat-sealing position; a heat-sealing cutter is used. The heat-sealing cutter is a commonly used accessory on a sealing machine, which melts plastic bags or composite films together by heating to achieve a sealing effect; the opening part of the packaging bag is sealed by heating and pressing, and parameters such as the temperature, pressure, and time of heat-sealing are controlled to complete the heat-sealing work. In traditional heat-sealing work, the operator needs to manually place the packaging bag on the hot air device and then complete the heat-sealing work, resulting in low work efficiency.

[0003] On this basis, through a search on the patent network, Chinese Patent Publication No. CN219545260U discloses a heat-sealing device for packaging bags, including a base and a housing. A displacement device is provided on the inner wall of the housing. The displacement device includes a support plate, and the upper end of the support plate is fixedly connected to the housing. The upper hot air sealing head slides on the surface of the packaging bag for heat-sealing. By using the upper hot air sealing head to slide and heat-seal at the sealing position of the packaging bag, the sealing of the packaging bag can be adjusted in time, so that there will be no wrinkles on the surface of the packaging bag, improving the packaging appearance and increasing the sales volume.

When directly using the heat-sealing cutter to seal the packaging bag, it is easy for the position of the bag to shift or even collapse, affecting the sealing work of the device on the packaging bag and reducing the use efficiency of the equipment.

[0005] In view of the above problems, a heat-sealing device and method for packaging bags are proposed. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. For a packaging bag heat-sealing device provided by the present invention, before using the device, first adjust the distance between the two heat-sealing cutters according to the thickness of the packaging bag. The heat-sealing cutters can be driven to expand and contract by controlling the telescopic movement of the automatic telescopic rod, and adjust the distance position of the two heat-sealing cutters according to the actual working needs. The present invention can place a group of sealed packaging bags on each support component. First, place the packaging bag filled with materials between the two limiting components, turn on the second motor, and the second motor starts the first roller to rotate forward or backward. Then, the two sliding cavity rods can move closer to or away from each other, and then the two limiting long plates make a distance adjustment on the placing table until the bottom of the packaging bag is limited and fixed by the two limiting components to prevent it from collapsing;

[0022] 2. After positioning the packaging bag, it is necessary to convey the packaging bag to the heat-sealing assembly, which relies on the driving component of the workbench. The operator turns on the first motor, and the concave moving block slides along the long connecting rod until the limited packaging bag is conveyed to the heat-sealing assembly. The user can simultaneously turn on two sets of second hydraulic cylinders, and the second hydraulic cylinders drive the exhaust blocks to extend. The two exhaust blocks approach the packaging bag at the same time and moderately press the bag, and the gas in the packaging bag is discharged by the two exhaust blocks.

[0023] 3. And the operator can control the telescopic movement of the two sets of first hydraulic cylinders to lift the placement table, thereby adjusting the height of the packaging bag, which is convenient for the user to adjust the sealing position of the packaging bag to the height corresponding to the position of the heat-sealing cutter.

[0024] 4. Subsequently, two sets of heat-sealing cutters are used to perform heat-sealing pressure on the sealing part of the packaging bag, and the heat-sealing assembly closes the through-hole of the packaging bag. The packaging bag continues to slide horizontally along the concave moving block in the direction close to the ventilation assembly. This setting realizes the function of the device to limit the packaging bag throughout the packaging process through the combined use of the workbench and the support assembly, improves the packaging effect, and avoids the situation of material outflow caused by the collapse of the bag. Moreover, the device can automatically perform the function of conveying the packaging bag, and the heat-sealing operation is automated and fast, which improves the working efficiency of the device.

[0025] 5. The sealed packaging bag continues to move horizontally by the transmission assembly of the workbench. When the first support assembly enters the lower end of the support groove block, the second conductive sheet on one side of the concave moving block contacts multiple first conductive sheets. At this time, the multiple first conductive sheets controlling the third motor and the second conductive sheet of the power supply assembly controlling the motor will form a closed circuit. At this time, the third motor can be powered on and its working mode can be turned on. Multiple fan blade components rotate and blow air, and the blown air blows towards the packaging bag through multiple through-holes. Ventilation is carried out at the heat-sealing position, which can blow and dissipate heat from the packaging position of the packaging bag, quickly shape the packaging position of the packaging bag, and at the same time avoid the surface temperature of the packaging bag being too hot to affect the operator's handling.

[0026] 6. After the blowing is completed, the packaging bag needs to continue to move the support assembly forward by the transmission assembly of the workbench until the concave moving block moves out of the support groove block. At this time, the first conductive sheet and the second conductive sheet move away from each other. When the first conductive sheet and the second conductive sheet are completely out of contact, the third motor can be powered off to turn off the disinfection mode. This operation saves electricity by using the device. Subsequently, the operator can remove the heat-sealed packaging bag from the support assembly, and the ventilation assembly is conducive to saving electricity and improving the overall applicable range of the device.

[0049] In summary, the working principle of the present invention: A heat-sealing device for packaging bags proposed by the present invention. Before using the device, first adjust the distance between the two groups of heat-sealing cutters 41 according to the thickness of the packaging bag. The heat-sealing cutters 41 can be driven to expand and contract by controlling the expansion and contraction of the automatic telescopic rod 42. Adjust the distance position of the two groups of heat-sealing cutters 41 according to the actual working needs. The present invention can place a group of sealed packaging bags on each support component 3. First, place the packaging bag filled with materials between the two limiting components 37. Start the second motor 371. The second motor 371 drives the first roller 372 to rotate forward or backward. Due to the connection of the long rod 373, the two first rollers 372 rotate simultaneously. Due to the transmission effect of the belt 374, the two second rollers 375 and the second lead screw 376 can rotate forward or backward. Then, the two sliding cavity rods 377 can move closer to or away from each other. Then, the two limiting long plates 378 adjust the distance on the placement table 33 until the bottom of the packaging bag is limited and fixed by the two limiting components 37 to prevent it from collapsing; after positioning the packaging bag, it is necessary to transfer the packaging bag to the heat-sealing component 4. It depends on the driving component of the workbench 1. The operator starts the first motor 13. The first motor 13 rotates to drive the first lead screw 14 to rotate. The first lead screw 14 drives the concave moving block 31 to move horizontally towards the heat-sealing component 4. The concave moving block 31 slides along the long connecting rod 12. The concave moving block 31 drives the placement table 33 and the packaging bag to be sealed to move until the limited packaging bag is transferred to the heat-sealing component 4. The user can simultaneously start the two second hydraulic cylinders 35. The second hydraulic cylinders 35 drive the exhaust blocks 36 to extend. The two exhaust blocks 36 approach the packaging bag simultaneously and moderately press the bag to discharge the gas in the packaging bag by the two exhaust blocks 36; and the operator can control the expansion and contraction of the two first hydraulic cylinders 32 to lift the placement table 33, thereby adjusting the height of the packaging bag to facilitate the user to adjust the sealing position of the packaging bag to the height corresponding to the heat-sealing cutter 41; subsequently, the two heat-sealing cutters 41 are used to perform heat-sealing pressure on the sealing position of the packaging bag. The heat-sealing component 4 closes the through hole of the packaging bag. The packaging bag continues to slide horizontally towards the ventilation component 2 by relying on the concave moving block 31. This setting realizes the function of the device to limit the packaging bag throughout the packaging process through the cooperation of the workbench 1 and the support component 3, improves the packaging effect, avoids the situation of material outflow caused by the collapse of the bag, and the device can automatically perform the function of transporting the packaging bag. The heat-sealing operation is automated and fast, improving the working efficiency of the device;

[0050] The packaged packaging bag continues to move horizontally by means of the transmission component of the workbench 1. When the support component 3 enters the lower end of the support groove block 21, the second conductive sheet 6 on one side of the concave moving block 31 comes into contact with multiple groups of first conductive sheets 5. At this time, the multiple groups of first conductive sheets 5 of the control third motor 24 and the second conductive sheet 6 of the power supply component 22 of the control motor form a closed circuit. At this time, the third motor 24 can be powered on and its working mode can be activated immediately. The third motor 24 drives the long rotating rod 25 to rotate. The long rotating rod 25 drives the second bevel gear 28, the first bevel gear 27 and the fan component 26 to rotate. Then, multiple groups of fan components 26 rotate and blow air. The blown air blows towards the packaging bag through multiple through holes 231. Ventilation is carried out at the heat-sealing position, and the packaging position of the packaging bag can be blown and cooled, so that the packaging position of the packaging bag is quickly shaped. At the same time, it is avoided that the surface temperature of the packaging bag is too hot to affect the operation of the operator. After the blowing is completed, the packaging bag needs to continue to move the support component 3 forward by means of the transmission component of the workbench 1 until the concave moving block 31 moves out of the support groove block 21. At this time, the first conductive sheet 5 and the second conductive sheet 6 move away from each other. When the first conductive sheet 5 and the second conductive sheet 6 are completely out of contact, the third motor 24 can be powered off to turn off the disinfection mode. This operation saves electricity by using the device. Subsequently, the operator can remove the heat-sealed packaging bag from the support component 3. This setting uses the ventilation component 2 to blow and cool the just heat-sealed packaging bag, so that the packaging position of the packaging bag is quickly shaped. At the same time, it is avoided that the surface temperature of the packaging bag is too hot to affect the operation of the operator. And the ventilation component 2 is conducive to saving electricity and improving the overall application range of the equipment.
