Description

Technical Field

[0001] The utility model belongs to the technical field of food packaging detection, in particular to a pressure detection device for food packaging production. Background Art

[0002] In food packaging production, pressure testing is a critical quality control step to ensure that the packaging materials and sealing process effectively protect the food, preventing leakage, contamination, or product spoilage. Pressure testing effectively safeguards the sealing, pressure resistance, and overall quality of food packaging, thereby ensuring food freshness and safety.

[0003] The pressure testing method for food packaging mainly applies vertical pressure to the packaging to simulate the stacking situation, so as to test whether the food packaging structure will be deformed or damaged under pressure. At present, there are some pressure testing equipment on the market. For example, a pressure testing machine for food packaging safety testing is disclosed on the China Patent Network, and its announcement number is CN212168220U. This pressure testing machine can be used for pressure testing of food packaging production, but there are some defects and deficiencies that need to be improved: (1) Due to structural design reasons, some existing pressure testing equipment can only perform pressure testing on a single package of the same batch. Each time a package is tested, it needs to be replaced with the next one, which is very cumbersome, thereby reducing the efficiency of the entire testing work; (2) When performing pressure testing on the package, some existing pressure testing equipment often only sets a sensor at the top position of the package, so that the sensor can only capture the pressure change at the top of the package, and it is difficult to capture the pressure change from multiple angles, thereby reducing the accuracy of pressure testing; (3) Some existing pressure testing equipment lacks effective moisture-proof measures, so that the ambient humidity is too high when performing pressure testing on food packaging, which not only affects the performance of the packaging material, but also interferes with the accuracy and reliability of the pressure testing equipment. Therefore, in order to solve the above problems, the pressure detection device for food packaging production provided by the present invention is of great significance. Utility Model Content

[0004] The utility model provides a pressure testing device for food packaging production. A pressing mechanism can apply vertical pressure to a food package, so as to assess the food package's ability to withstand pressure during transportation or storage by monitoring pressure changes and deformation of the food package. Multiple testing slots can simultaneously accommodate multiple food packages from the same batch, thereby enabling batch pressure testing of multiple food packages from the same batch without the need to frequently replace the next package after each test. This not only greatly improves the efficiency of the entire pressure testing process but also effectively reduces the workload of testers. A first pressure sensor, a second pressure sensor, and a third pressure sensor can respectively capture pressure changes at the top, bottom, front, and rear sides of each food package during pressure testing, thereby achieving multi-point testing of the food package and greatly improving the accuracy of pressure testing. A desiccant can be placed in a drying rack. The desiccant can fully absorb moisture within each testing slot and around the pressure testing device through the drying holes and moisture absorption port, thereby achieving a drying and moisture-proofing effect. This effectively prevents excessive humidity during pressure testing from affecting the performance of the food packaging material and interfering with the accuracy and reliability of the pressure testing equipment. The above-mentioned problems in the prior art are solved.

[0032] See also Figure 1-7 As shown, the utility model is a pressure detection device for food packaging production, comprising a support plate 1, a plurality of support legs 2 being fixedly connected to the bottom of the support plate 1, and a detection frame 3 and a fixed frame 4 being fixedly connected to the top of the support plate 1, respectively. The fixed frame 4 is located at the rear side of the detection frame 3, and its side surface is L-shaped, and a top pressing mechanism is provided on the fixed frame 4, a drying frame 5 is fixedly connected to the top inner wall of the detection frame 3, and a groove 6 is provided on the top of the detection frame 3, and the groove 6 is rectangular, and a plurality of drying holes 7 are provided at the bottom of the groove, a detection platform 8 is installed on the top of the detection frame 3, a second pressure sensor 9 is installed on the bottom of the detection platform 8, and a plurality of detection slots 10 are provided on the top of the detection platform 8, each detection slot 10 can be placed in the same batch of food packages to be detected, and a positioning mechanism is provided on the front and rear sides of the detection frame 3;

[0033] The pressing mechanism includes a first electric telescopic rod 11, which is mounted on the top of the fixed frame 4. The bottom end of the output shaft of the first electric telescopic rod 11 is fixedly connected to a first pressure sensor 12, and the bottom of the first pressure sensor 12 is fixedly connected to a pressing plate 13. By driving the first electric telescopic rod 11, the first pressure sensor 12 and the pressing plate 13 can be driven to move up and down. When the pressing plate 13 contacts the food packages in each detection slot 10, vertical pressure can be applied to each food package. At this time, by monitoring the pressure change and the deformation of the food package, the system can evaluate the ability of the food package to withstand pressure during transportation or storage. If the food package does not show structural damage or deformation during the test, its pressure resistance is determined to be qualified. During the pressure test, the first pressure sensor 12 and the second pressure sensor 9 can respectively capture the pressure changes at the top and bottom of each food package.

[0034] The positioning mechanism includes a bracket 14, the side of the bracket 14 is L-shaped, and its bottom end is fixedly connected to the front end and rear end of the detection frame 3, and a second electric telescopic rod 15 is installed on one side of the bracket 14, and the end of the output shaft of the second electric telescopic rod 15 is fixedly connected to the third pressure sensor 16, and the third pressure sensor 16 is fixedly connected to the positioning plate 17. By driving the second electric telescopic rod 15, the third pressure sensor 16 can be driven to move together with the positioning plate 17.

The pressure changes on the front and rear sides of each food package can be captured respectively by the third pressure sensor 16.

[0035] Among them, the top pressure plate 13 is located directly above the detection table 8, and a layer of buffer pad 18 is provided on its bottom surface. The buffer pad 18 is made of elastic materials such as rubber and is fixed by glue or other means. When the top pressure plate 13 contacts each food package, the buffer pad 18 can play a buffering and protective role to avoid direct contact between the top of the food package and the top pressure plate 13 to cause collision and wear.

[0036] Among them, a number of anti-slip pads 19 are provided on the side wall surface of the positioning plate 17. The anti-slip pads 19 are long strips and are equidistantly linearly distributed along the length direction of the positioning plate 17. The surface of the anti-slip pads 19 is engraved with herringbone anti-slip grooves. The anti-slip pads 19 are made of elastic materials such as rubber and are fixed by glue or other means. When the positioning plate 17 contacts each food package, the anti-slip grooves on the surface of the anti-slip pads 19 can increase the friction between the food package and the positioning plate 17 to play an anti-slip role, thereby further improving the clamping and fixing effect of the positioning plate 17.

[0037] Among them, the inner walls on both sides of the detection frame 3 are fixedly connected with reinforcement blocks 20. The reinforcement blocks 20 are triangular, and their tops are fixedly connected to the top inner walls of the detection frame 3. The reinforcement blocks 20 can support and reinforce the detection frame 3 to improve the structural strength of the detection frame 3, thereby preventing it from deforming after being subjected to stress for a long time.

[0038] Among them, the detection grooves 10 are rectangular and are equidistantly linearly distributed along the length direction of the detection platform 8, and the length and width of each detection groove 10 are correspondingly equal. Multiple food packages of the same batch can be placed at the same time through multiple detection grooves 10. When performing pressure testing, the top pressure plate 13 can contact the food packages in each detection groove 10 at the same time, so that batch pressure testing can be performed on multiple food packages of the same batch at the same time without frequently replacing the next one after each testing. This not only greatly improves the efficiency of the entire pressure testing work, but also effectively reduces the workload of the testing personnel.

[0039] Among them, the drying holes 7 are equidistantly distributed linearly along the length direction of the groove 6, and each drying hole 7 is connected to the drying rack 5. A pair of moisture absorption ports 21 are opened at the bottom of each detection groove 10. The moisture absorption ports 21 are rectangular and symmetrically distributed. A desiccant can be placed in the drying rack 5. The desiccant can fully absorb moisture in each detection groove 10 and around the pressure detection device through each drying hole 7 and the moisture absorption port 21, so as to play a role in drying and moisture-proofing, thereby effectively preventing the ambient humidity from being too high during pressure detection, thereby affecting the performance of the food packaging material and disturbing the accuracy and reliability of the pressure detection equipment.

[0040] Among them, a number of positioning cylinders 22 are fixedly connected to the top of the detection frame 3, and a number of positioning columns 23 are fixedly connected to the bottom of the detection table 8. The number of positioning columns 23 and the positioning cylinders 22 are the same, the diameters are equal, and the center of each positioning column 23 corresponds one-to-one to the center of each positioning cylinder 22. When the detection table 8 is placed on the top of the detection frame 3, each positioning column 23 can be aligned and inserted into the corresponding positioning cylinder 22. At this time, the detection table 8 can be fixed by the mutual cooperation between the positioning columns 23 and the positioning cylinders 22. By pulling out the positioning columns 23, the detection table 8 can be removed from the detection frame 3 so that the detection table 8 can be maintained or replaced.

When the top pressure plate 13 contacts the food packages in the respective detection slots 10, vertical pressure can be applied to each food package. At this time, by monitoring the pressure changes and the deformation of the food packages, the system can evaluate the ability of the food packages to withstand pressure during transportation or storage. If the food packages do not show any structural damage or deformation during the test, it is determined that their pressure resistance is qualified. When performing pressure detection, the first pressure sensor 12 is used to detect the food packages. , the second pressure sensor 9, and the third pressure sensor 16 can respectively capture the pressure changes on the top, bottom, front and back sides of each food package to realize multi-point detection of food packages, thereby greatly improving the accuracy of pressure detection.
