[0002] Food packaging bags are plastic or paper products used to package and protect food. They not only protect food from contamination but also extend the shelf life. Food packaging bag edge sealing is used to seal the packaging bag, so that the entire packaging bag can be sealed, which is convenient for later food packaging and storage.

[0003] Edge sealing equipment is mostly composed of a machine body, a driving mechanism and a hot pressing mechanism. When producing food packaging bags, the machine body needs to be installed on the production line, the packaging bags to be sealed are passed through the machine body, and the driving mechanism is used to drive the hot pressing mechanism to contact the packaging bags. The heat generated by the hot pressing mechanism is used to make the edges of the packaging bags stick together, thus completing the edge sealing of the packaging bags.

[0004] In the current existing technology, most traditional edge sealing equipment is only suitable for packaging bags of specific types or sizes and lacks flexibility. When changing the type of packaging bags, it is not convenient for workers to quickly adjust the edge sealing structure, which affects the edge sealing efficiency of food packaging bag production and reduces the practicability and use efficiency of the equipment.

[0005] Therefore, in view of the above problems, a food packaging bag edge sealing device is proposed. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specific examples are given below.

[0026] See also Figure 1 - Figure 4 The utility model provides a food packaging bag edge sealing device, including a workbench 1 and an edge sealing mechanism 3. A positioning groove 2 is provided on one side of the top of the workbench 1. Multiple positioning blocks 4 are fixedly connected to both sides of the edge sealing mechanism 3. A hydraulic push rod 5 is fixedly connected to the middle of each positioning block 4, and one end of each hydraulic push rod 5 is fixedly connected to the workbench 1. The edge sealing mechanism 3 moves up and down on the top of the workbench 1 through multiple hydraulic push rods 5. A second sealing position 8 and a first motor 9 are provided on one side of the bottom of the edge sealing mechanism 3. Two sliders 14 are arranged inside the second sealing position 8 and the first motor 9. A bidirectional threaded rod 12 is threadedly connected to the middle of each of the two sliders 14, and both ends of each bidirectional threaded rod 12 are rotatably connected to the inner wall of the edge sealing mechanism 3. A first motor 9 is fixedly connected to one side of the edge sealing mechanism 3, and one end of the output shaft of the first motor 9 is fixedly connected to one end of a bidirectional threaded rod 12. A second motor 10 is fixedly connected to the other side of the edge sealing mechanism 3, and the output shaft of the second motor 10 is fixedly connected to one end of another bidirectional threaded rod 12. The inner wall of each slider 14 is fixedly connected with a plurality of electric push rods 16, and one end of each of the plurality of electric push rods 16 is fixedly connected with a heat sealing plate 18. Each heat sealing plate 18 moves up and down inside the second sealing position 8 and the first motor 9 through the plurality of electric push rods 16. A heating component 19 is fixedly connected inside each heat sealing plate 18.

[0027] During operation, the food packaging bag to be edge-sealed is placed inside the positioning groove 2, and the heating component 19 is connected to the internal circuit of the edge-sealing mechanism 3. The edge-sealing mechanism 3 is used to control the heating component 19 to work, and the heat-sealing plate 18 can be heated. Then, the hydraulic push rod 5 is used to push the positioning block 4 to drive the edge-sealing mechanism 3 to move downward on the top of the workbench 1, so that the edge-sealing mechanism 3 falls and drives the heat-sealing plate 18 to fall. Then, multiple electric push rods 16 are used to simultaneously push the heat-sealing plate 18 to contact the edge of the food packaging bag. The heat of the heat-sealing plate 18 is used to make the edges of the packaging bag bonded together. And the edge-sealing mechanism 3 can control the operation of the electric push rods 16 individually or simultaneously, so that when edge-sealing, it can be ensured that the unsealed side of the packaging bag will not contact the heat-sealing plate 18. It can meet the sealing requirements of food packaging bag production, and then complete the edge-sealing work of the food packaging bag. When the type or size of the packaging bag changes, the output shaft of the first motor 9 is used to drive the bidirectional threaded rod 12 to rotate, so that the two sliders 14 slide inside the first sealing position 7. The output shaft of the second motor 10 is then used to drive the bidirectional threaded rod 12 to rotate, so that the other two sliders 14 slide inside the second sealing position 8. Then, the position adjustment of the heat sealing plate 18 can be completed. With the above method, the staff can quickly adjust the position of the heat sealing plate 18, thereby improving the edge sealing efficiency of food packaging bag production and improving the practicality and use efficiency of the equipment.

[0028] Further, such as Figure 2 and Figure 5 As shown, a return spring 6 is fixedly connected to one side of the bottom of each positioning block 4, each return spring 6 is sleeved on the outside of the hydraulic push rod 5, and the other end of each return spring 6 is fixedly connected to the workbench 1. A second spring 17 is sleeved on the outer wall of each electric push rod 16, and one end of each second spring 17 is fixedly connected to the heat-sealed plate 18.

[0029] During operation, the contraction or extension of the hydraulic push rod 5 can drive the edge sealing mechanism 3 and the positioning block 4 to move, and the elastic force of the return spring 6 can improve the anti-seismic effect of the structure, reduce energy loss, and increase the service life of the hydraulic push rod 5. When the electric push rod 16 is used to push the heat sealing plate 18 to fall, the elastic force of the second spring 17 is used to allow the heat sealing plate 18 to have a certain activity space, so as to prevent the heat sealing plate 18 from pressing the packaging bag too tightly when the edge sealing mechanism 3 falls, causing the packaging bag to rupture, thereby improving the edge sealing efficiency of the packaging bag.

[0030] Further, such as Figure 3 and Figure 4As shown, a plurality of rubber pressure plates 11 are fixedly connected to one side of the bottom of the edge sealing mechanism 3, two rubber pressure plates 11 are symmetrically arranged on both sides of the first sealing position 7, and the other two rubber pressure plates 11 are symmetrically arranged on both sides of the second sealing position 8, and each rubber pressure plate 11 is fitted with the inner wall of the positioning groove 2 through the edge sealing mechanism 3. A limiting ring 13 is fixedly connected to the middle of each bidirectional threaded rod 12, and each limiting ring 13 is arranged between two sliders 14. Sliding rods 15 are slidably connected to the inner walls of both ends of each two sliders 14, and both ends of the two sliding rods 15 are fixedly connected to the inner wall of the first sealing position 7, and both ends of the other two sliding rods 15 are fixedly connected to the inner wall of the second sealing position 8, and the middle of each sliding rod 15 is also fixedly connected to the limiting ring 13.

[0031] During operation, the edge sealing mechanism 3 is driven to fall by contraction of the multiple hydraulic push rods 5, so that the multiple rubber pressure plates 11 are attached to both sides of the packaging bag. The rubber pressure plates 11 can be used to press the two ends of the packaging bag to prevent the packaging bag from being misplaced or folded during edge sealing, thereby improving the edge sealing effect of the packaging bag. The rubber pressure plates 11 can also be used to prevent the heat sealing plate 18 from directly contacting the packaging bag at the first time, thereby reducing the possibility of damage to the packaging bag. When adjusting the position of the heat sealing plate 18, the setting of the limit ring 13 can prevent the collision between the two sliders 14. The slide bar 15 can then be used to prevent the slider 14 from being misplaced during movement, thereby ensuring the stability of the heat sealing plate 18 and improving the service life and practicality of the equipment.

[0032] Working principle: By placing the food packaging bag to be edge-sealed inside the positioning groove 2, connecting the heating component 19 with the internal circuit of the edge-sealing mechanism 3, and controlling the heating component 19 to work by the edge-sealing mechanism 3, the heat-sealing plate 18 can be heated. Then, the positioning block 4 can be pushed by the hydraulic push rod 5 to drive the edge-sealing mechanism 3 to move downward on the top of the workbench 1. The rubber pressing plate 11 can be used to press the two ends of the packaging bag. Then, multiple electric push rods 16 are used to simultaneously push the heat-sealing plate 18 to contact the edge of the food packaging bag, and the heat of the heat-sealing plate 18 is used to make the edges of the packaging bag bonded together. The edge-sealing mechanism 3 can control the operation of the electric push rods 16 individually or simultaneously, so that when edge-sealing, it can be ensured that the unsealed side of the packaging bag will not contact the heat-sealing plate 18, thereby completing the edge-sealing work of the food packaging bag. When the type or size of the packaging bag changes, the output shaft of the first motor 9 is used to drive the bidirectional threaded rod 12 to rotate, so that the two sliders 14 slide inside the first sealing position 7, and then the output shaft of the second motor 10 is used to drive the bidirectional threaded rod 12 to rotate, so that the other two sliders 14 slide inside the second sealing position 8. The setting of the limit ring 13 can prevent the collision between the two sliders 14. The slide rod 15 can prevent the slider 14 from being misplaced during the movement process. Then the position adjustment of the heat sealing plate 18 can be completed.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
