Description
Technical Field
[0001] This utility model relates to the field of food testing, specifically a food bag sealing device for food testing. Background Technology
[0002] Food safety testing involves detecting harmful substances in food according to national standards, primarily targeting harmful and toxic indicators such as heavy metals and aflatoxin. An important aspect of food science and engineering is the introduction and application of chemical unit operations, which has led to the development of food engineering unit operations. This promotes the development of the food industry towards large-scale, continuous, and automated processes. After food testing is completed, the food bags need to be sealed.
[0003] Currently, food bags are typically sealed by hand or heat-sealing adhesive, which is a rather cumbersome process. The varying heights and contents of food bags result in different sealing positions at the opening, and the bags are not easily secured when filled with food, making them prone to tipping over and spilling, leading to contamination or waste. This affects the convenience and practicality of sealing food bags. Therefore, a food bag sealing device for food testing needs to be designed to solve these problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1
[0023] Please refer to Figure 1-5 As shown, this utility model provides a food bag sealing device for food testing, including a support frame 1, a sliding through hole 2 at the top of the support frame 1, a driving component slidably connected inside the sliding through hole 2, a sealing component for sealing the food bag installed at the bottom of the driving component, and a support component for supporting the food bag installed at the top of the support frame 1.
[0024] Furthermore, the sliding through hole 2 can provide a sliding path for the driving component, which can drive the sealing component to move laterally. After the sealing component clamps the opening of the food bag and moves, it heat-seales the food bag. The support component can support and clamp the food bag containing food upwards to prevent the food bag from tilting or falling off and causing spillage and waste.
[0025] Specifically, the driving component includes a sliding block 3 that is slidably connected to the inside of the sliding through hole 2. A driving frame 4 is fixedly connected to the bottom of the sliding block 3. A cylinder 5 is installed at one end of the support frame 1. A push rod 6 extends from one end of the cylinder 5. A sliding hole 23 is opened at the top of the support frame 1 on the other side of the sliding through hole 2. A limit block 24 is fixedly connected to one end of the mounting frame 10 near the top. The limit block 24 is slidably connected to the sliding hole 23. The other end of the push rod 6 is fixedly connected to the sliding block 3.
[0026] Among them, the air cylinder 5 can drive the sliding block 3 to slide in the sliding through hole 2 through the push rod 6. The cross-section of the sliding block 3 is in the shape of a Chinese character 'Wang'. The sliding block 3 is embedded in the sliding through hole 2 to slide, so that the driving frame 4 at the bottom of the sliding block 3 can move horizontally. The limiting block 24 can support and limit the driving frame 4, prevent the driving frame 4 from shifting, increase the stability of the horizontal movement of the driving frame 4, and improve the convenience of the driving frame 4 to seal the opening of the food bag.
[0027] More specifically, the sealing member includes a bidirectional screw rod 7 penetrating through the inner side of the driving frame 4. A motor 8 is installed at one end of the driving frame 4 and at one end of the bidirectional screw rod 7. Two driving blocks 9 are sleeved outside the bidirectional screw rod 7. A mounting frame 10 is fixedly connected to the bottom of the driving block 9. A heat conduction strip 11 penetrates through one side of one mounting frame 10. A plurality of uniformly arranged fixing rods 12 are fixedly connected to the inner side of the other mounting frame 10. A pressing bag wheel 13 is sleeved outside the fixing rod 12. The pressing bag wheel 13 is rotatably connected to the fixing rod 12. The heat conduction strip 11 and the mounting frame 10 are installed by a plurality of bolts.
[0028] It should be added that the motor 8 can drive the bidirectional screw rod 7 to rotate. The bidirectional screw rod 7 drives the mounting frames 10 at the bottoms of the two driving blocks 9 to approach or move away from each other. The cross-section of the heat conduction strip 11 is triangular, and the cross-section of the pressing bag wheel 13 is concave triangular. The heat conduction strip 11 presses and closes the opening of the food bag while performing hot-melt adhesion near the pressing bag wheel 13. The driving frame 4 can drive the two mounting frames 10 to move horizontally. When the food bag moves, it drives the pressing bag wheel 13 to rotate outside the fixing rod 12.
[0029] Furthermore, the supporting member includes two guiding rods 14 fixedly connected to the inside of the supporting frame 1. A first spring 16 for supporting the sliding plate 15 is sleeved outside the guiding rods 14 at the bottom of the supporting frame 1. A baffle 17 is fixedly connected to the top of the sliding plate 15 and near one side. A fixing plate 18 is fixedly connected to the sliding plate 15 and near the other side. A pull rod 19 penetrates through one side of the fixing plate 18. A clamping plate 20 is fixedly connected to one end of the pull rod 19. Second springs 21 are sleeved at both ends of the pull rod 19. An anti-detachment plate 22 is fixedly connected to the guiding rod 14 near the middle. The guiding rod 14 penetrates through the sliding plate 15 and is slidably connected to it. Both ends of the first spring 16 are fixedly connected to the supporting frame 1 and the sliding plate 15 respectively.
[0030] Specifically, the sliding plate 15 is pressed down as needed, and the first spring 16 on the outside of the guide rod 14 can support the sliding plate 15 upward. The anti-detachment plate 22 on the outside of the guide rod 14 can limit the sliding plate 15 to prevent it from moving too high. The sliding plate 15 can support food bags of different heights and capacities upward. The pull rod 19 has a U-shaped cross section, and the second spring 21 on the outside of the pull rod 19 can squeeze the clamping plate 20. The clamping plate 20 and the baffle 17 can clamp and fix the food bag. The middle part of the clamping plate 20 and the baffle 17 is arc-shaped to prevent the clamping plate 20 and the baffle 17 from getting too close to the food bag and causing the food to break, spill or fall.
[0031] Working principle: First, place the food bag on the sliding plate 15, then slowly release the pull rod 19. At this time, the second spring 21 squeezes and pushes the clamping plate 20. The clamping plate 20 and the baffle 17 clamp and fix the food bag. Then, adjust the height of the sliding plate 15 according to the sealing position. Then, start the cylinder 5 and the motor 8, and simultaneously heat the heat-conducting strip 11. The motor 8 drives the bidirectional lead screw 7 to rotate. At this time, the bidirectional lead screw 7 drives the mounting brackets 10 at the bottom of the two driving blocks 9 to move closer to each other. At the same time, the heat-conducting strip 11 moves close to the pressure wheel 13 to squeeze and close the opening of the food bag. At the same time, the heat-conducting strip 11 heat-seals the opening of the food bag. Meanwhile, the cylinder 5 drives the sliding block 3 to slide in the sliding through hole 2 through the push rod 6. At the same time, the sliding block 3 drives the two mounting brackets 10 to move laterally through the driving bracket 4.
