Description

Technical Field

[0001] The invention relates to the technical field of sealing test, in particular to a sealing safety detection device for prefabricated meat packaging. Background Art

[0002] The safety test of the sealing of pre-prepared meat packaging can ensure food quality, extend shelf life, prevent contamination, and protect the health and safety of consumers. The sealing of the package determines the degree to which the contents of the package are independent of the external environment. If the sealing of the package is poor, the gas content or composition inside the package is prone to change, such as gas penetration into the package or the gas filled inside the package is lost, which will cause the contents to become moldy, agglomerated, bulging, and other quality problems, thus affecting the overall quality of the food. Therefore, it is necessary to use a detection device to test its sealing.

[0003] The prior art uses a device for testing the sealing safety of prefabricated meat packaging to determine whether the package is leaking by placing the prefabricated meat product package in water and observing whether bubbles appear. However, this solution requires manual visual observation, which results in large errors, and it is difficult to efficiently detect and discover tiny leaks. On the other hand, detection by immersion can only be used for a small number of packaging materials, and the overall detection efficiency is low. Once a leaky prefabricated meat package is detected, the water used for detection will directly penetrate into the interior, making it impossible to repackage the food inside, ultimately resulting in waste.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7The present invention provides the following technical solutions: a prefabricated meat packaging sealing safety detection device, comprising a detection device body, the detection device body comprising a detection channel 1, a detection mechanism 5 and a vacuum mechanism 4, the bottom of the detection channel 1 is welded with a bottom plate 3, the top of the detection channel 1 is provided with a delivery port 2, one end of the bottom plate 3 is integrally formed with a front end plate 19, the surface of the front end plate 19 is screwed with a motor 18, the output end of the motor 18 is plugged with a screw rod 17, the detection mechanism 5 is embedded in the interior of the detection channel 1, and the bottom of the detection mechanism 5 A threaded sleeve 29 is provided in the middle position, and the screw rod 17 passes through the inside of the threaded sleeve 29. The other end of the bottom plate 3 is integrally formed with a rear end plate 16. A top closing component 6 is inserted into one end of the detection channel 1, and the top closing component 6 is inserted into the upper area of ​​the rear end plate 16. The end of the vacuum mechanism 4 is connected with a plug-in pipe 35, and the plug-in pipe 35 passes downward from the top of the detection channel 1, and the end of the plug-in pipe 35 is used to be embedded in the inside of the detection mechanism 5. A side closing component 7 is embedded in one side of the inside of the detection channel 1. The prefabricated meat packaging sealing safety detection device is used to detect the sealing state of the prefabricated meat packaging product.

[0029] When the present invention is used, the theoretical value of the air pressure in a non-leaking state is first measured. The theoretical value is obtained by measuring in advance. The specific process is as follows: a packaging bag that has been determined to have qualified sealing properties is placed in the detection chamber 24, the connecting chamber 30 and the vacuum chamber 31 are vacuumed, the plug-in pipe 35 is pulled out, and the air in the detection chamber 24 enters the connecting chamber 30 and the vacuum chamber 31. At this time, the value measured by the air pressure monitoring module 28 is "the theoretical value detected if the packaging bag is not leaking." If the air pressure value obtained by subsequent measurement of each packaging bag is greater than the theoretical value, it means that the packaging bag has a leak. In subsequent batch measurement, the prefabricated meat packaging products are transported to the position of the delivery port 2 one by one through the front-end conveying equipment, and the prefabricated meat packaging products are placed in the delivery port 2 through an automated robotic arm or manually, so that the prefabricated meat packaging products pass through the feed port 22 and fall into the detection chamber 24 inside the detection box 21. Then the motor 18 at the bottom can be started, and the motor 18 cooperates with the screw rod 17 and the threaded sleeve 29 to drive the entire detection mechanism 5 to move along the detection channel 1 until it moves to the vacuum mechanism 4. After the bottom is reached, the vacuum pump 36 on the top is started to evacuate the vacuum chamber 31 at the bottom of the detection box 21 and the interior of the connecting chamber 30, and the current air pressure data is obtained through the air pressure monitoring module 28, and then the plug-in pipe 35 is taken out. In this state, the detection box 21 as a whole is still in a sealed state, and in the subsequent process of pushing the detection box 21 toward the end by the motor 18, the air pressure change inside the detection box 21 during this period of time is obtained through the pressure monitoring module, and according to the obtained data, it is determined whether the prefabricated meat packaging product placed therein has leaked, and the specific extent of the leakage. After the plug-in pipe 35 is pulled out, if the packaging bag to be tested is in a sealed state, only a fixed amount of air in the detection chamber 24 can flow into the connecting chamber 30 and the vacuum chamber 31. The volume of this part of air is fixed. At this time, the air pressure value measured is equal to the theoretical value. If the packaging bag leaks, in addition to the fixed amount of air in the detection chamber 24 flowing out, the air in the leaked packaging bag will also escape into the connecting chamber 30 and the vacuum chamber 31. Therefore, the air pressure value measured in this state will be greater than the theoretical value measured when there is no leakage, and it can be determined that the packaging bag is in a leaking state at this time.

[0030] In this embodiment, the detection mechanism 5 includes a detection box 21, a feed port 22 and a discharge port 23. The interior of the detection box 21 is divided into a detection chamber 24, a connecting groove 34, a connecting chamber 30 and a vacuum chamber 31. A hole is provided between the connecting groove 34 and the connecting chamber 30. The connecting groove 34 and the detection chamber 24 are separated by a top partition 25. A top through hole 26 is provided on the surface of the top partition 25. The connecting chamber 30 and the vacuum chamber 31 are separated by a bottom partition 32. A bottom through hole 33 is provided on the surface of the bottom partition 32. A plug-in hole 27 is provided on the top of the detection box 21. A feed port 22 is provided on the top of the detection chamber 24. A discharge port 23 is provided on the side of the detection chamber 24. The top of the feed port 22 fits with the top closing component 6 or the top of the inner wall of the detection channel 1. The side of the discharge port 23 fits with the side closing component 7. An air pressure monitoring module 28 is screwed onto the inner wall of the connecting chamber 30, the threaded sleeve 29 is integrally formed at the bottom of the vacuum chamber 31, the bottom of the detection box 21 is pressed against the surface of the bottom plate 3, and the end of the screw rod 17 is embedded in the surface of the rear end plate 16 through a bearing.

[0031] The detection mechanism 5 is controlled by the motor 18 at the bottom to perform linear reciprocating motion along the detection channel 1, and the prefabricated meat packaging product to be tested can be directly placed from one end during the movement, and can continue to move after vacuuming, and complete the detection purpose during the movement. The overall degree of automation is high, and it can judge whether there is a leakage or the specific degree of leakage through the value or change of air pressure, so that more detailed sealing data can be obtained.

[0032] Specifically, after the prefabricated meat packaged product is placed into the detection chamber 24, the air in the connecting chamber 30 is evacuated with the help of the vacuum mechanism 4. At this time, the air in the vacuum chamber 31 can be synchronously evacuated through the bottom partition 32 and the bottom through hole 33. At this time, the connecting chamber 30 and the vacuum chamber 31 are blocked by the plug-in pipe 35 themselves, so as to maintain the vacuum state until the vacuum pipe is pulled out of the detection box 21. At this time, the air in the detection chamber 24 and the air in the connecting groove 34 will enter the vacuum chamber at the bottom and be detected by the air pressure monitoring module 28. If the placed prefabricated meat packaged product has a leakage problem, it will cause The air inside the prefabricated meat packaging product also enters the connecting chamber 30 synchronously with the airflow inside the detection chamber 24, which will cause the air pressure recovery value of the connecting chamber 30 to be greater than the theoretical value. At this time, it can be determined that the detected prefabricated meat packaging product has a leakage problem. At the same time, if the leakage speed of the prefabricated meat packaging product is slow, then in the subsequent monitoring process of the air pressure monitoring module 28, the air inside the prefabricated meat packaging product will be slowly discharged to interfere with the air pressure inside the connecting chamber 30 at the bottom. Therefore, the air pressure monitoring module 28 can monitor that the air pressure is in a state of continuous recovery, and judge the degree of slow leakage of the prefabricated meat packaging product from the recovery speed.

[0033] In this embodiment, the vacuum pumping mechanism 4 includes a vacuum pump 36 and a plug-in pipe 35, one end of the vacuum pump 36 is plugged with an air extraction pipe 37, the surface of the detection channel 1 is screwed with an electric lifting rod 39, the top of the electric lifting rod 39 is screwed with a lifting plate 38, and the bottom middle of the lifting plate 38 is integrally formed with a plug-in pipe 35. The end of the air extraction pipe 37 is embedded in the surface of the lifting plate 38 and communicates with the inside of the plug-in pipe 35. The end of the surface of the plug-in pipe 35 is provided with an air extraction hole 40, and the plug-in pipe 35 passes through the top of the detection channel 1, the plug-in hole 27, and the inside of the connecting groove 34 in sequence and is then embedded in the connecting chamber 30. The sealing state of the prefabricated meat packaging is judged by the change in air pressure. Even if an unsealed prefabricated meat product is encountered, it can still be recycled and repackaged for use after detection, which will not pollute the internal meat products, avoid waste, and do not need to contact with soaking water, thereby avoiding the subsequent step of drying the surface of the prefabricated meat packaging bag, simplifying the subsequent processing flow.

[0034] Specifically, by starting the electric lifting rod 39, the lifting plate 38 can be driven to move downward, and then the plug-in pipe 35 at the bottom can be driven to be embedded in the plug-in hole 27, and then pass through the connecting groove 34 into the connecting chamber 30, and the air inside the connecting chamber 30 and the vacuum chamber 31 is extracted. During the whole process, the air inside the detection box 21 is blocked by the plug-in pipe 35 and remains in a closed state until the plug-in pipe 35 is pulled out. Since the plug-in pipe 35 is still stuck in the top shell of the detection channel 1, and the top of the detection box 21 is still in contact with the top of the inner wall of the detection channel 1, the internal aperture of the detection box 21 can still be controlled to remain in a relatively closed state, and only the air inside the connecting groove 34 and the detection chamber 24 can enter the connecting chamber 30 and the vacuum chamber 31, while the outside air cannot enter.

[0035] In this embodiment, the top closing assembly 6 includes a top closing plate 8 and a first baffle 9, the first baffle 9 is integrally formed at the bottom of one end of the top closing plate 8, and a first spring rod 10 is welded to the rear end of the first baffle 9. The surface of the top closing plate 8 is embedded in the top of the inner wall of the detection channel 1, the first spring rod 10 passes through the surface of the rear end plate 16, the side of the detection box 21 is against the inner side of the first baffle 9, and the cross-section of the top closing plate 8 and the first baffle 9 connected is an "L"-shaped structure. The side closing assembly 7 includes a side closing plate 12 and a second baffle 13, a translation channel 20 is opened on the side of the detection channel 1, the side closing plate 12 and the second baffle 13 are embedded in the translation channel 20, and a second spring rod 14 is welded to the side of the second baffle 13, and telescopic sleeves 11 are welded at both ends of the detection channel 1, and the first spring rod 10 and the second spring rod 14 are embedded in the telescopic sleeve 11. The surfaces of the top closing plate 8 and the side closing plate 12 are both mounted with sealing pads 15, and the cross section where the side closing plate 12 and the second baffle plate 13 are connected is a "T"-shaped structure. In the process of controlling the detection mechanism 5 to move along the detection channel 1 for detection, the top closing component 6 and the side closing component 7 can be used to ensure that the surface of the detection mechanism 5 provides efficient sealing in the moving state, and no heavy friction with the external structure occurs, thereby reducing the wear problem, extending the service life, and reducing the wear degree of the entire detection device during the moving detection process.

[0036] Specifically, when the detection mechanism 5 is driven to move by starting the motor 18, refer to Figure 1 and Figure 2After the detection box 21 is pushed from the bottom of the vacuum mechanism 4 toward the left end, the top of the detection box 21 will be transferred from leaning against the top of the inner wall of the detection channel 1 to leaning against the top closing plate 8 area, and then the side of the detection box 21 will contact the inner side of the first baffle 9, and the entire top closing plate 8 can be pushed toward the left synchronously. In this process, whether the detection box 21 leans against the top of the inner wall of the detection channel 1 or the top closing plate 8, it can ensure that the feed port 22 is partially closed to prevent external air from entering, and the side closing component 7 is always applied by the second spring rod 14. The thrust ensures that the second baffle 13 and the side closing plate 12 are always synchronized with the detection box 21 Move until the detection box 21 moves out of the position of the detection channel 1. At this time, the second spring rod 14 reaches a relaxed state, so the discharge port 23 moves out of the coverage of the side closing plate 12, and the prefabricated meat packaging products inside can be directly dropped outward along the inclined plate. When the motor 18 is started again to pull and reset the detection box 21, the top closing component 6 can be pushed by the first spring rod 10 to ensure that the top closing component 6 is reset synchronously with the detection box 21. In most positions during the entire moving process, the discharge port 23 and the feed port 22 of the detection box 21 always remain relatively still with the sealing gaskets 15 on the surfaces of the side closing plates 12 and the top closing plate 8, thereby reducing the wear problem of the sealing gaskets 15.
