Description

An inflation volume detection device Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to an inflation volume detection device. Background Technology

[0002] In the food processing industry, in order to ensure the quality of puffed foods (such as French fries and potato chips), gas needs to be filled into the puffed food packaging bags to ensure that the puffed foods are not crushed during processing and transportation. After the packaging bags are sealed, the inflation status of the packaging bags needs to be tested to prevent over-inflated or under-inflated packaging bags from entering the market.

[0003] Currently, when testing the inflation volume of a packaging bag, it is necessary to manually open the cover on top of the testing tank, then manually place the packaging bag into the liquid, and infer the inflation volume by observing the change in the liquid level before and after placement. After the test is completed, the cover is manually opened again, and the packaging bag is manually removed. During the testing process, the placement and removal of the packaging bag, as well as the opening and closing of the cover, all need to be performed separately. Furthermore, when removing the bag, it is necessary to put one's hand into the tank, making the process of removing the packaging bag inconvenient. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an inflation volume detection device for detecting the inflation volume of puffed food packaging bags, so as to solve the problem that the existing devices are inconvenient to remove the packaging bags from the liquid.

[0005] This utility model provides an inflation volume detection device, comprising:

Two sets of guide rods are symmetrically arranged at the bottom of the cover plate. The guide rods slide vertically through the first mounting ring, and the bottom of the guide rods is fixedly connected to the placement basket. The opening of the placement basket faces upward and is used to place the packaging bag to be tested.

[0010] The pressing component is located directly above the placement basket and is used to press down on the packaging bag inside the placement basket;

[0011] A laser rangefinder sensor is installed inside the second opening to detect the liquid level of the auxiliary liquid in the second water tank.

[0012] Furthermore, a second mounting ring is fixedly provided at the bottom of the guide rod. The second mounting ring is arranged in a horizontal direction, and the basket is fixedly arranged in the inner ring of the second mounting ring.

[0013] Furthermore, a plurality of rubber limiting blocks are evenly arranged on the top of the second mounting ring along its circumference.

[0014] Furthermore, the pressing assembly includes a sliding rod, a spring, and a pressing plate.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0031] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Please refer to Figures 1 to 4. An embodiment of this utility model provides an inflation volume detection device, including a first water tank 1, a second water tank 2, a lifting assembly 3, a pressing assembly 4, and a laser rangefinder sensor 5; wherein,

[0033] The first water tank 1 has a first opening on its top, and a first mounting ring 11 is fixedly installed at the first opening;

[0034] The second water tank 2 has a second opening at its top and its bottom is connected to the bottom of the first water tank 1;

[0035] The auxiliary liquid is contained in the first water tank 1 and the second water tank 2; specifically, the auxiliary liquid can be mineral oil.

[0036] The lifting assembly 3 includes a cover plate 31, guide rods 32, and a placement basket 33. The cover plate 31 is located directly above the first opening. Two sets of guide rods 32 are symmetrically arranged at the bottom of the cover plate 31. The guide rods slide vertically through the first mounting ring 11, and the bottom of the guide rods 32 is fixedly connected to the placement basket 33. The opening of the placement basket 33 faces upward and is used to place the packaging bag to be tested. Specifically, the placement basket 33 is provided with several water-permeable meshes so that the auxiliary liquid can flow into the placement basket 33, thereby immersing the packaging bag in the auxiliary liquid.

[0037] The pressing component 4 is located directly above the mesh basket 33 and is used to press down on the packaging bags inside the mesh basket 33.

[0038] The laser rangefinder 5 is installed inside the second opening and is used to detect the liquid level of the auxiliary liquid in the second water tank 2.

[0039] In this embodiment, the size of the first opening is larger than the size of the placement basket 33, so that the placement basket 33 can slide up and down within the first opening, thereby realizing the actions of putting in and taking out the packaging bag.

[0040] The first water tank 1 and the second water tank 2 of this application are connected to form a communicating vessel. When detecting the inflation volume of puffed food packaging bags, the initial liquid level in the second water tank 2 is first detected by the laser range sensor 5. Then, the cover plate 31 is pulled up and the packaging bag is placed in the placement basket 33. Subsequently, the packaging bag is pressed and limited by the pressing component 4, and then the cover plate 31 is pushed down. When the bottom surface of the cover plate 31 is in contact with the top surface of the first mounting ring 11, the packaging bag is completely immersed in the auxiliary liquid. Utilizing the principle of communicating vessels, the liquid levels in both the first water tank 1 and the second water tank 2 rise. At this time, the liquid level in the second water tank 2 is detected again by the laser range sensor 5. The inflation volume in the packaging bag is calculated by inferring the change in liquid level, thereby realizing the detection of the inflation volume in the packaging bag and preventing products that do not meet the inflation specifications from entering the market.

[0041] After the test is completed, manually lift the cover plate 31 upwards. During the process of lifting the cover plate 31, the mesh basket 33 will also be lifted up, making it easy to directly remove the packaging bag. The cover plate 31 is opened and the packaging bag is removed at the same time in one lifting action, without the operator having to put their hands into the liquid to take it out, which improves the convenience of the packaging bag removal process.

[0042] In a preferred embodiment, as shown in Figures 2 and 3, a second mounting ring 34 is fixedly provided at the bottom of the guide rod 32. The second mounting ring 34 is arranged in a horizontal direction, and the basket 33 is fixedly arranged in the inner ring of the second mounting ring 34.

[0043] In this embodiment, the second mounting ring 34 provides an installation base for the placement of the wire mesh basket 33, and the placement of the wire mesh basket 33 and the second mounting ring 34 are fixedly connected by welding.

[0044] In a preferred embodiment, as shown in Figures 3 and 4, a plurality of rubber limiting blocks 35 are uniformly arranged on the top of the second mounting ring 34 along its circumference.

[0045] In this embodiment, the rubber limiting block 35 serves as a limiting element to prevent the second mounting ring 34 from colliding hard with the bottom surface of the first mounting ring 11 during the upward lifting of the cover plate 31.

[0046] In a preferred embodiment, as shown in Figures 3 and 4, the pressing assembly 4 includes a slide rod 41, a spring 42, and a pressing plate 43. The pressing plate 43 is located directly above the basket 33, and two sets of slide rods 41 are symmetrically arranged on the top of the pressing plate 43. The slide rods 41 slide vertically through the cover plate 31. The spring 42 is sleeved on the outside of the slide rods 41, and one end of the spring 42 is fixedly connected to the bottom of the cover plate 31, and the other end is fixedly connected to the top of the pressing plate 43.

[0047] In this embodiment, before placing the packaging bag to be tested into the placement basket 33, the pressing plate 43 is manually pushed upwards to move it upwards and compress the spring 42. Then, the packaging bag is placed into the placement basket 33. After that, the pressing plate 43 is released, and under the elastic action of the spring 42, it moves downwards and presses against the top surface of the packaging bag, thereby fixing the packaging bag. When the placement basket 33 is placed into the auxiliary liquid, the packaging bag can be completely submerged in the auxiliary liquid, avoiding the packaging bag from floating in the auxiliary liquid and causing detection errors.

[0048] In a preferred embodiment, as shown in FIG3, a limiting plate 44 is fixedly provided on the top of the slide bar 42.

[0049] In this embodiment, the limiting plate 44 serves to limit the movement and prevent the slide rod 42 from detaching from the cover plate 31.

[0050] In a preferred embodiment, as shown in FIG3, a lifting handle 36 is fixedly provided on the top of the cover plate 31. Specifically, the lifting handle 36 facilitates the lifting or lowering of the cover plate 31.

[0051] In a preferred embodiment, the system further includes a controller and an operation screen, both of which are electrically connected to the controller.

[0052] In this embodiment, the controller can analyze and calculate the liquid level value detected by the laser rangefinder 5, convert the liquid level difference into the inflation value of the packaging bag, and the detected liquid level value and inflation value are displayed on the operation screen, so that the operator can intuitively judge whether the inflation value of the tested packaging bag is qualified.

[0053] The control panel also has an execution button. When no packaging bag is placed in the basket 33, the bottom surface of the cover plate 31 is attached to the top surface of the first mounting ring 11. At this time, pressing the execution button will cause the laser range sensor 5 to detect the initial liquid level in the second water tank 2. When a packaging bag is placed in the basket 33, the bottom surface of the cover plate 31 is attached to the top surface of the first mounting ring 11 again. At this time, pressing the execution button will cause the laser range sensor 5 to detect the detection liquid level in the second water tank 2. The controller analyzes and calculates the initial liquid level value and the detected liquid level value, and converts the liquid level difference into the inflation volume of the packaging bag. The detected liquid level value and inflation value are displayed on the control panel, which makes it easy for the operator to intuitively judge whether the inflation value of the tested packaging bag is qualified.

[0054] Before each package bag is tested, the initial liquid level in the second water tank 2 needs to be checked, and then the test liquid level after the package bag is placed in is checked, and the cycle is repeated.
