Description

Technical Field

[0001] The present invention relates to the technical field of sealing detection devices, and in particular to a sealing detection device for moon cake packaging bags. Background Art

[0002] As the food industry's requirements for food safety and quality control become more and more stringent, the importance of packaging sealing testing for mooncakes, a food widely consumed during the traditional Chinese festival Mid-Autumn Festival, has become increasingly prominent. Mid-Autumn Festival is not only a day for family reunion, but also a wonderful time to give gifts to relatives and friends, and mooncakes are an indispensable part of this festival culture. However, if there is a problem with the sealing of the mooncake packaging, then whether it is given to relatives and friends or enjoyed at home, the beautiful meaning of the festival may be lost due to quality problems. Once the packaging sealing is unqualified, microorganisms, moisture and other pollutants in the outside air may invade, causing the mooncakes to deteriorate or be contaminated prematurely. For example, mold may grow and multiply in a short period of time, making the mooncakes that should be sweet and delicious difficult to eat, and even produce toxins, which are harmful to human health. In addition, oil oxidation may also cause mooncakes to lose their original flavor and affect the taste.

[0003] Most of the existing mooncake packaging sealing detection methods rely on manual inspection or relatively basic negative pressure or positive pressure tests. Although manual inspection is intuitive, there are subjective judgment errors, high labor intensity and low efficiency; and although traditional negative pressure or positive pressure tests can preliminarily verify whether the package is leaking, due to equipment and technical limitations, the detection accuracy is often not high enough, and it is impossible to fully cover small leakage points, which is prone to missed detection. These methods are obviously incapable of meeting the needs of mass production and cannot meet the needs of the modern food industry for fast and accurate detection. Summary of the invention

[0004] In order to overcome the shortcomings of low efficiency and low precision of the existing packaging bag sealing detection technology, the purpose of the present invention is to provide a high-efficiency and high-precision mooncake packaging bag sealing detection device.

DETAILED DESCRIPTION

[0025] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] Embodiment: A moon cake packaging bag sealing detection device, such as Figure 1-Figure 8 As shown, it includes a bracket 1, a mounting plate 2, a fixed plate 201, an electric slide rail 3, a cylinder 4, a pressure plate 5, a movable plate 6, a first screw 7 and an inflation mechanism. The mounting plate 2 is fixedly connected to the top of the bracket 1, and the fixed plates 201 are fixedly connected to the front and rear sides of the bottom of the mounting plate 2. The electric slide rail 3 is fixedly connected inside the mounting plate 2. A through hole for the packaging bag to fall out is opened on the slider 301 of the electric slide rail 3. The cylinder 4 is fixedly connected to the slider 301 of the electric slide rail 3. The pressure plate 5 is fixedly connected to the piston rod of the cylinder 4. The movable plate 6 is slidably connected to the through hole of the slider 301 of the electric slide rail 3. The first screw 7 is threadedly connected to the slider 301. The movable plate 6 is rotatably connected to the first screw 7, and the inflation mechanism is connected to the movable plate 6.

[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the inflation mechanism includes an air cushion 14, a bellows 15, a sliding rod 16 and a connecting plate 17. The air cushion 14 is fixedly connected to the left side of the movable plate 6, the bellows 15 is fixedly connected to the right side of the movable plate 6, the sliding rod 16 is fixedly connected to the right side of the movable plate 6, the connecting plate 17 is slidingly connected to the right side of the sliding rod 16, the bellows 15 is located between the movable plate 6 and the connecting plate 17, the sliding rod 16 is located inside the bellows 15, and the bellows 15 is connected to the air cushion 14.

[0028] When testing the sealing of the mooncake packaging bag, the mooncake packaging bag is placed on the slider 301, and the mooncake packaging bag is located between the pressing plate 5 and the movable plate 6. The pressing plate 5 is then driven by the cylinder 4 to move closer to the mooncake packaging bag, and the pressing plate 5 reaches the maximum extension distance, so that the mooncake packaging bag is squeezed. The packaging bag that is not tightly sealed will leak when being squeezed. The slider 301 drives the cylinder 4 to slide rightward, so that the mooncake packaging bag moves to the right, and the inflation mechanism continuously inflates the air cushion 14, so that the pressure between the pressing plate 5 and the movable plate 6 increases. In the process of the mooncake packaging bag moving to the right, the packaging bag that is not tightly sealed continues to leak, causing its volume to decrease, so that the packaging bag that is not tightly sealed is separated from between the pressing plate 5 and the movable plate 6, and then falls out of the through hole of the slider 301. The sealed packaging bag can be moved to the right to the specified position, and then the cylinder 4 drives the pressure plate 5 to move in the opposite direction away from the sealed packaging bag, so that the sealed packaging bag is separated from the pressure plate 5 and the movable plate 6, and then falls from the through hole of the slider 301 to the specified position, so that the poorly sealed packaging bags and the sealed packaging bags can be distinguished, and they can be dropped in categories for easy collection, thereby improving the working efficiency of the detection device. After the packaging bag is separated from the pressure plate 5 and the movable plate 6, the slider 301 drives the cylinder 4 and the movable plate 6 to reset, and the distance between the movable plate 6 and the pressure plate 5 can be reduced by rotating the first screw 7, so that the detection device can perform sealing detection on different moon cakes, thereby improving the applicability of the detection device.

[0029] When the slider 301 moves to the right, the bellows 15 is compressed while moving along the sliding rod 16, so that the air therein enters the air cushion 14. After the air cushion 14 is inflated, it squeezes the packaging bag, so that the packaging bag can be further tested for air leakage. In the process of the slider 301 sliding to the right, the air pressure in the air cushion 14 gradually increases, and the sliding rod 16 gradually extends to the right. When the slider 301 is reset, the bellows 15 moves in the opposite direction along the sliding rod 16 and returns to its original state, so that the air in the air cushion 14 re-enters the bellows 15. The air cushion 14 returns to its original state, and the inflation mechanism can further squeeze the packaging bag, thereby ensuring that the packaging bag can be completely squeezed, further adapting to packaging bags of different sizes, and being able to improve the working efficiency and accuracy of the detection device, reduce the occurrence of missed detection, and after reducing the distance between the movable plate 6 and the pressure plate 5, the bellows 15 is stretched.

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, it also includes a first blanking frame 8, a second blanking frame 9, a sliding frame 10, a fixed frame 11 and a baffle 101. The sliding frame 10 and the first blanking frame 8 are connected between the fixed plates 201 on the front and rear sides. The second blanking frame 9 is connected to the bottom of the sliding frame 10. The fixed frame 11 is connected to the sliding frame 10. The connecting plate 17 is connected to the fixed frame 11. The baffle 101 is fixedly connected to the left and right sides of the sliding frame 10, and the left side of the baffle 101 is lower than the right side. When the slider 301 moves to the right, the loosely sealed packaging bags will fall out of the first blanking frame 8, and the fully sealed packaging bags will fall out of the second blanking frame 9. The sliding frame 10 is moved to adjust the distance between the second blanking frame 9 and the first blanking frame 8, so that the packaging bags of different sizes and with complete seals can accurately fall into the second blanking frame 9, avoiding the mixing of loosely sealed packaging bags and fully sealed packaging bags. The baffle 101 can prevent the fully sealed packaging bags from falling on the right side of the second blanking frame 9, and can also prevent the loosely sealed packaging bags from falling into the second blanking frame 9 from the left side.

[0031] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, it also includes a trigger block 12, a button 13, a connecting block 18 and a second screw 19. The movable plate 6 is fixedly connected with the trigger block 12, and the fixed frame 11 is fixedly connected with the button 13 for controlling the extension and retraction of the cylinder 4. The trigger block 12 and the button 13 are in the same straight line, and the button 13 is electrically connected to the cylinder 4. The rear side of the sliding frame 10 is fixedly connected with the connecting block 18, and the second screw 19 is threadedly connected to the connecting block 18. The second screw 19 is contact-connected with the mounting plate 2. When the slider 301 moves to the right, the trigger block 12 on the movable plate 6 will squeeze the trigger button 13, so that the cylinder 4 drives the pressure plate 5 away from the movable plate 6, thereby loosening the sealed packaging bag and making the packaging bag fall into the second unloading frame 9, thereby improving the automation level of the detection device. When the packaging bag is tested for sealing, after the position of the sliding frame 10 is adjusted, the second screw 19 is rotated to make it close to the rear side of the mounting plate 2, so that the sliding frame 10 can be fixed to ensure that the trigger block 12 and the button 13 can be in normal contact.

[0032] like Figure 2 , Figure 3 and Figure 6As shown, it also includes a visual detector 401. The visual detector 401 is installed on both the upper and lower sides of the right part of the cylinder 4. The pressing plate 5 is provided with a through hole for the visual detector 401 to pass through. The cylinder 4 is provided with a controller, and the visual detector 401 is electrically connected to the controller. When the packaging bag is placed between the pressing plate 5 and the movable plate 6, the visual detector 401 first detects the sealing part of the packaging bag. When it is detected that the sealing part is obviously not tightly sealed, the slider 301 drives the packaging bag with a loose seal to move above the first unloading frame 8, and then the cylinder 4 is controlled by the controller to move the pressing plate 5 away from the packaging bag with a loose seal, so that the packaging bag with a loose seal falls into the first unloading basket. The packaging bag that is not detected by the visual detector 401 and is obviously not tightly sealed moves to the right for subsequent detection steps, which can speed up the detection speed of the detection device and further improve the work efficiency.

[0033] like Figure 1 , Figure 2 and Figure 8 As shown, it also includes a belt conveyor 20, a fixed frame 21, a guide plate 22 and an elastic member 23. The belt conveyor 20 is installed on the mounting plate 2. The fixed frames 21 are fixedly connected to the left and right sides of the mounting plate 2. The fixed frames 21 are both located below the belt conveyor 20. The guide plates 22 are slidably connected to the sides of the left and right fixed frames 21 that are close to each other. The upper side of the guide plate 22 is inclined, and the left side of the top of the guide plate 22 is lower than the right side of the top. Two elastic members 23 are fixedly connected between the guide plate 22 and the fixed frame 21. The elastic force of the elastic member 23 is less than the gravity of the packaging bag, and the elastic member 23 is configured as a coil spring. The packaging bag is conveyed by the belt conveyor 20. When the packaging bag falls from the belt conveyor 20 between the left and right fixed frames 21, the belt conveyor 20 stops working until the slider 301 is reset. The packaging bag will squeeze the guide plate 22, so that the left and right guide plates 22 are separated from each other, and the elastic member 23 is compressed. When the packaging bag falls between the pressure plate 5 and the movable plate 6, the elastic member 23 returns to its original state to reset the guide plate 22. The guide plate 22 can transform the moon cake from a horizontal placement state to a vertical placement state, ensuring that the moon cake is in a vertical state when placed between the pressure plate 5 and the movable plate 6, further improving the working efficiency and detection accuracy of the detection device.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
