Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a sampling and testing device for fruit canning production. Background Technology

[0002] Fruit canning is a type of food made in a sealable container using sheet metal, glass, plastic, cardboard, or a combination of these materials. It contains fruit that has undergone specific treatment to achieve commercial sterility and can be kept at room temperature for an extended period without spoiling.

[0003] Patent CN112403081A discloses a sampling and testing auxiliary device for canned fruit. The sample is poured into a separation chamber, where the liquid enters the lower part of the chamber through a leak, while the solids remain on a baffle. A motor drives a stirring shaft to rotate, cutting the magnetic lines of force generated by a magnet and energizing a coil. The energized coil attracts an iron block to the right, causing a circular track to rotate. This rotation moves a pressing component, which in turn rotates and opens a switch. The pressing component pushes a pressing plate to compress an air bladder, which in turn pushes a piston plate upwards. The piston plate then forces a push rod against the left side of the baffle. The solids on the baffle then enter the mixing chamber as the baffle tilts to the right, achieving the separation of solids and liquids in the sample and sending the solids into the mixing chamber for further stirring.

[0004] The aforementioned sampling and testing device directly opens the fruit cans and performs solid-liquid separation to test the food safety and quality of the contents. The main cause of spoilage inside the fruit cans is loosening of the can lid, allowing external air to enter. Therefore, there is a gap between the can body and the lid of a spoiled fruit can. The device opens each sampled fruit can and tests it through a separate chamber. Therefore, all fruit cans, regardless of spoilage status, must be opened for testing. Unspoiled fruit cans, due to contact with the water-sprayed testing chamber, cannot be repackaged and sold, resulting in food waste. Furthermore, the structure requires opening all the lids of the sampled cans, leading to slow testing speed and affecting the normal production time of the fruit cans. Utility Model Content

[0005] In view of the need to further improve the detection efficiency of the sampling and testing device used in the production of canned fruit, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a sampling and testing device for fruit canning production, comprising a placement plate, wherein a plurality of mounting holes are arranged in an array on the placement plate, and a partition frame is disposed outside the plurality of mounting holes;

[0007] It also includes a water tank, with a tank cover hinged to the upper end of the water tank, pull rods on both sides of the tank cover near the water tank, and fixed plates at both ends of the bottom of the water tank. A connecting rod is provided on one side of the fixed plate, and the middle area of ​​the connecting rod is hinged to one side of the fixed plate. One end of the connecting rod is hinged to the other end of the pull rod, and the other end of the connecting rod is hinged to one end of the placement plate.

[0008] As a preferred embodiment of the sampling and testing device for fruit canning production described in this utility model, the placement plate is provided with several through holes, and the four side walls of the partition frame are provided with water inlet holes.

[0009] In a preferred embodiment of the sampling and testing device for fruit canning production described in this utility model, a bend is provided at the hinge joint between the connecting rod and the fixed plate.

[0010] As a preferred embodiment of the sampling and testing device for fruit canning production described in this utility model, a balance bar is hinged to the side of the fixing plate near the connecting rod, and the other end of the balance bar is hinged to the side of the placement plate that is hinged to the connecting rod.

[0011] As a preferred embodiment of the sampling and testing device for fruit canning production described in this utility model, the lid of the can has grooves on both sides of the side near the water tank, and a support rod is hinged in the groove.

[0012] As a preferred embodiment of the sampling and testing device for fruit canning production described in this utility model, the water tank has sliding grooves on both sides of its upper end, and an installation groove is provided in the sliding groove on the side near the lid of the tank. A spring is provided in the installation groove, and a slider is connected to the other end of the spring. The slider is slidably installed in the sliding groove.

[0013] The beneficial effects of this utility model are:

[0014] By pulling the lid, the lever acts as a connecting rod. The bend at the hinge of the connecting rod and the fixed plate causes the connecting rod to extend or retract the placement plate. Under the limit of the balance bar, the placement plate remains horizontal. After the canned fruit in the mounting holes of the placement plate is submerged in the water in the tank, observe whether small bubbles rise from all the canned fruit. If so, it indicates that there is a gap between the lid and the can, and air has entered the can, causing the canned fruit to spoil. At this point, sample sampling and testing can be completed quickly. This testing method can quickly identify whether the canned fruit has spoiled, while also preserving the unspoiled canned fruit intact, avoiding waste. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Reference Figure 1-3 This is the first embodiment of the present invention, which provides a sampling and testing device for fruit canning production. The sampling and testing device for fruit canning production includes a placement plate 1, which has a plurality of through holes. A water inlet hole is provided on the four side walls of the partition frame 12. A plurality of mounting holes 11 are arranged in an array on the placement plate 1. A partition frame 12 is provided on the outside of the plurality of mounting holes 11. The partition frame isolates adjacent fruit cans to avoid mutual interference between adjacent fruit cans during the testing process.

[0027] It also includes a water tank 2. The inner wall of the water tank 2 is provided with an electric heating element on the side near the tank cover 21. The electric heating element is activated by electrical energy, so that the electric heating element starts to heat up. The heat is conducted from the electric heating element to the water molecules in contact, so that the water in the water tank 2 is heated. The tank cover 21 is hinged to the upper end of the water tank 2. An observation plate is provided in the middle area of ​​the tank cover 21. The observation plate is made of transparent acrylic sheet. Pull rods 22 are hinged to both sides of the side of the tank cover 21 near the water tank 2. Fixing plates 23 are fixedly installed at both ends of the bottom of the water tank 2. A connecting rod 24 is provided on one side of the fixing plate 23, and the middle area of ​​the connecting rod 24 is hinged to one side of the fixing plate 23. A bend is provided at the hinge point of the connecting rod 24 and the fixing plate 23. One end of the connecting rod 24 is hinged to the other end of the pull rod 22, and the other end of the connecting rod 24 is hinged to one end of the placement plate 1.

[0028] A balance bar 25 is hinged to the side of the fixed plate 23 near the connecting rod 24. The other end of the balance bar 25 is hinged to the side of the placement plate 1 that is hinged to the connecting rod 24. The balance bar 25 and the pull rod 22 are always in a horizontal and parallel state. Under the limit of the balance bar 25, the placement plate 1 is kept in a horizontal state during the displacement process, which improves the stability of the fruit cans placed in the mounting holes 11 opened in the placement plate 1 and prevents the fruit cans from falling off during the inspection process.

[0029] During use, firstly, an appropriate amount of water is injected into the water tank 2. At this time, the end of the lid 21 that is away from the water tank 2 is separated from the water tank 2. Then, the water monster can to be tested is snapped into several mounting holes 11. Then, the lid 21 is pulled. At this time, the lid 21 rotates around the hinge point with the water tank 2. Then, the end of the pull rod 22 that is away from the lid 21 will push the connecting rod 24, so that the connecting rod 24 rotates around the hinge point with the fixed plate 23. This causes the connecting rod 24 to drive the placement plate 1 to retract into the water tank 2. At the same time, the balance rod 25 moves synchronously with the connecting rod 24 to limit the placement plate 1, so that the placement plate 1 can always remain horizontal during the movement.

[0030] At this point, the placement plate 1 will immerse several cans of fruit in the water. The water will be heated by an electric heating element. When the water is heated to a suitable temperature, observe whether there are continuous small bubbles rising in the water to determine the airtightness of the canned fruit and whether the contents have deteriorated.

[0031] Example 2

[0032] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0033] The tank cover 21 has grooves on both sides of the side closest to the water tank 2. A support rod 211 is hinged in the groove. When the tank cover 21 is opened, the support rod 211 hangs down under the action of gravity.

[0034] The upper end of the water tank 2 has sliding grooves on both sides. The side of the sliding groove near the tank cover has an installation groove. A spring 26 is installed in the installation groove. The other end of the spring 26 is connected to a slider 27. The upper surface of the slider 27 has several slots. When the tank cover 21 is away from the water tank 1, one end of the support rod 211 will be engaged in the slot and support the tank cover under the action of the support rod. The slider 27 is slidably installed in the sliding groove. A sliding rod is fixedly installed at the end of the slider 27 away from the spring 26. The sliding rod is slidably installed in the sliding groove. A beam is provided at the other end of the sliding rod.

[0035] During use, when the fruit can is inserted into the mounting hole 11, the support rod 211 is inserted into the slot on the surface of the slider 27. Then, the beam is pulled to make the slider 27 slide in the slot. Then the spring 26 is deformed and stretched. As the slider 27 moves, the support rod 211 will be retracted into the groove.

[0036] At this time, the cover 21 is closed with the water tank 2, and then the beam rod is released. Under the action of the spring 26, the slider 27 will return to its original position.

[0037] The remaining structure is the same as that in Example 1.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
