Description

Technical Field

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

[0002] In food testing, the firmness of fruits is typically tested. The degree of firmness in different fruits has a significant impact on their taste, and for some fruits, the degree of firmness determines their ripeness, thus allowing for the estimation of their harvest time. Currently, when using firmness testing devices to measure the firmness of fruits, workers usually need to hold the fruit with their hands until the testing head is inserted, which is cumbersome, time-consuming, and labor-intensive. To address these issues, existing technologies have proposed solutions.

[0003] For example, Chinese Patent Publication No. CN219265993U discloses a device for testing the hardness of food, including a base plate and a hardness tester. A support rod, an electric telescopic rod, and a worktable are fixedly connected to the upper end of the base plate. A sliding seat is slidably connected to the circumferential surface of the support rod. The hardness tester is fixedly installed at the front end of the sliding seat. A detection head is fixedly connected to the lower end of the hardness tester. One end of each of the two racks is fixedly connected to two clamping plates. A bearing frame is fixedly connected to the lower end of the worktable. A rotating shaft is rotatably connected inside the bearing frame and rotatably connected to the worktable. A gear is fixedly connected to the circumferential surface of the rotating shaft, and the gear meshes with the racks. This invention, through the action of the clamping plates, ensures that the fruit whose hardness needs to be tested is stably positioned at the upper end of the worktable, thus saving the worker's physical strength, eliminating the need for the worker to hold the fruit continuously, and ensuring more accurate hardness testing of the fruit.

[0004] However, when using this device, because different fruits have different shapes, the two clamping plates in the device have a small contact area with the fruit when clamping a spherical fruit, making it difficult to hold the spherical fruit stably. During testing, the fruit is easily deflected by force, affecting the accuracy of the test. At the same time, the fixed position of the worktable makes it inconvenient to place the fruit and take out the fruit after testing.

[0005] Therefore, it is necessary to provide a device for detecting the hardness of food to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a food hardness testing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: A food hardness testing device includes a base plate, a vertical rod fixed to the top side of the base plate, a sliding block slidably connected to the side of the vertical rod, a hardness tester fixed to the end of the sliding block facing the center of the base plate, a testing head provided at the bottom end of the hardness tester, an electric telescopic rod fixed to the top side of the base plate, the output end of the electric telescopic rod fixed to the sliding block, a placement plate provided above the base plate, a sliding groove arranged along the length of the base plate fixed to the top side of the base plate, a bottom slider that slides and is adapted to the sliding groove fixed to the bottom end of the placement plate, a positioning component for positioning the placement plate, and a clamping component for multi-point clamping of fruit provided at the top of the placement plate.

[0008] As a further embodiment of this utility model, the clamping assembly includes an annular seat fixed to the top side of the placement plate. The annular seat has a cavity inside. A first connecting cylinder communicating with the cavity is fixed on the inner side wall of the annular seat. Multiple first connecting cylinders are provided and arranged in an annular pattern. A connecting rod is inserted into the first connecting cylinder. A first piston plate that fits tightly against the inner side wall of the first connecting cylinder is fixed to one end of the connecting rod inside the first connecting cylinder. A clamping plate is fixed to one end of the connecting rod outside the first connecting cylinder.

[0009] As a further embodiment of this utility model, a second connecting cylinder communicating with the cavity is fixed on the outer wall of the annular seat. A threaded rod is internally threaded to one end of the second connecting cylinder away from the annular seat. A second piston plate that fits tightly against the inner wall of the second connecting cylinder is fixed to one end of the threaded rod located inside the second connecting cylinder.

[0010] As a further embodiment of this utility model, an end plate is fixed on one end of the threaded rod located outside the second connecting cylinder, and a rubber sleeve is fitted onto the surface of the end plate.

[0011] As a further embodiment of this utility model, the positioning component includes a protruding plate fixed to one end of the placement plate, a pin slidably inserted into the protruding plate, and a socket for fitting the pin is opened on the top side of the base plate.

[0012] As a further embodiment of this utility model, a rubber pad is attached and fixed to the side of the clamping plate away from the connecting rod, and the area of ​​the rubber pad is equal to the area of ​​the side of the clamping plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The clamping components hold the fruit at multiple points, which helps to distribute the pressure evenly. This allows for the clamping and fixing of fruits of different shapes while improving the stability of the fruit clamping. Compared to other methods, it has better clamping stability and a wider range of clamping applications.

[0015] 2. After the test is completed, the locking of the placement plate is released by the positioning component. Pulling the placement plate causes the bottom slider to slide in the groove. The movement of the placement plate is limited and guided by the cooperation of the groove and the bottom slider. This allows the placement plate to be pulled out from directly below the hardness tester, making it easier to remove the tested fruit and place the next fruit for testing. This makes it easier to place the fruit and facilitates the testing process. Attached Figure Description

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Please see Figure 1-5This utility model provides a food hardness testing device, including a base plate 3, a vertical rod 6 fixed to the top side of the base plate 3, a sliding block 7 slidably connected to the side of the vertical rod 6, a hardness tester 8 fixed to the end of the sliding block 7 facing the center of the base plate 3, a testing head 9 provided at the bottom end of the hardness tester 8, an electric telescopic rod 5 fixed to the top side of the base plate 3, the output end of the electric telescopic rod 5 fixed to the sliding block 7, a placement plate 4 provided above the base plate 3, a sliding groove 10 arranged along the length direction of the base plate 3 fixed to the top side of the base plate 3, a bottom slider 11 slidably adapted to the sliding groove 10 fixed to the bottom end of the placement plate 4, a positioning component 2 for positioning the placement plate 4, and a clamping component 1 for multi-point clamping of fruit provided at the top of the placement plate 4; during testing, the fruit is placed on the top side of the placement plate 4 and located inside the clamping component 1, and the fruit is clamped at multiple points by the clamping component 1. The clamping mechanism helps to evenly distribute pressure, thus securing fruits of different shapes while improving the stability of the clamping. Compared to other clamping methods, it offers better clamping stability and a wider range of applications, allowing the fruit to be stably positioned on the placement plate 4. Next, the electric telescopic rod 5 is activated. The output end of the electric telescopic rod 5 drives the sliding block 7 downwards, which in turn drives the hardness tester 8 downwards, allowing the testing head 9 at the bottom of the hardness tester 8 to be inserted into the fruit for hardness testing. After testing, the positioning component 2 releases the lock on the placement plate 4, and the placement plate 4 is pulled. The placement plate 4 drives the bottom slider 11 to slide within the slide groove 10. The cooperation between the slide groove 10 and the bottom slider 11 limits and guides the movement of the placement plate 4, allowing it to be pulled out from directly below the hardness tester 8. This facilitates the removal of the tested fruit and the placement of the next fruit for testing, making fruit placement and testing more convenient.

[0026] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the clamping assembly 1 includes an annular seat 101 fixed to the top side of the placement plate 4. The annular seat 101 has a cavity 102 inside. A first connecting cylinder 103 communicating with the cavity 102 is fixed to the inner wall of the annular seat 101. Multiple first connecting cylinders 103 are arranged in a ring. A connecting rod 105 is inserted into each first connecting cylinder 103. One end of the connecting rod 105 located inside the first connecting cylinder 103 is fixed with a connecting rod 105. A first piston plate 104 fits tightly against the inner wall of the connecting sleeve 103. A clamping plate 106 is fixed to one end of the connecting rod 105 located outside the first connecting sleeve 103. A second connecting sleeve 108 communicating with the cavity 102 is fixed to the outer wall of the annular seat 101. A threaded rod 109 is internally threaded to one end of the second connecting sleeve 108 away from the annular seat 101. A second piston plate 110, which fits tightly against the inner wall of the second connecting sleeve 108, is fixed to one end of the threaded rod 109 located inside the second connecting sleeve 108. In practice, the fruit is placed on the top side of the placement plate 4 and inside the annular seat 101. The cavity 102 and the first connecting cylinder 103 are filled with liquids that can flow between them. The liquid can be water or hydraulic oil. By rotating the threaded rod 109, the threaded rod 109 drives the second piston plate 110 to move inside the second connecting cylinder 108. The second piston plate 110 squeezes the liquid in the second connecting cylinder 108 into the cavity 102. This hydraulically pushes multiple first piston plates 104 to move inside multiple first connecting cylinders 103, which in turn pushes multiple connecting rods 105 and clamping plates 106 to move closer to the center of the annular seat 101. The fruit is then clamped at multiple points by the multiple clamping plates 106, so that the fruit can be stably placed on the placement plate 4. Multi-point clamping helps to evenly distribute pressure, thereby clamping and fixing fruits of different shapes while improving the stability of the fruit clamping. Compared with other methods, it has better clamping stability and a wider clamping range.

[0027] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth noting that the positioning component 2 includes a protruding plate 201 fixed to one end of the placement plate 4. A pin 202 is slidably inserted into the protruding plate 201. A socket 203 that matches the pin 202 is opened on the top side of the base plate 3. In specific operation, during testing, the placement plate 4 is locked by inserting the pin 202 into the socket 203 to prevent the placement plate 4 from shifting. After the test is completed, the placement plate 4 is unlocked by pulling the pin 202 out of the socket 203, which makes it easy to pull out the placement plate 4 and take out the tested fruit and place the next fruit to be tested.

[0028] This solution has the following working process: During testing, the pin 202 is inserted into the socket 203 to lock the placement plate 4, preventing it from shifting. The fruit is placed on the top side of the placement plate 4 and inside the annular seat 101. By rotating the threaded rod 109, the threaded rod 109 drives the second piston plate 110 to move inside the second connecting cylinder 108. This forces the liquid inside the second connecting cylinder 108 into the cavity 102 through the second piston plate 110. This hydraulically pushes multiple first piston plates 104 to move within multiple first connecting cylinders 103, thereby pushing multiple connecting rods 105 and clamping plates 106 to move closer to the center of the annular seat 101. This, in turn, causes the multiple clamping plates 106 to move. The fruit is clamped at multiple points to ensure it is stably positioned on the placement plate 4. The electric telescopic rod 5 is then activated, causing the sliding block 7 to move downwards via its output end. This, in turn, moves the hardness tester 8 downwards, allowing the testing head 9 at the bottom of the hardness tester 8 to be inserted into the fruit for hardness testing. After the test is completed, the pin 202 is pulled out of the insertion hole 203 to release the lock on the placement plate 4. Pulling the placement plate 4 causes the bottom slider 11 to slide within the groove 10. The cooperation between the groove 10 and the bottom slider 11 limits and guides the movement of the placement plate 4, making it easy to pull out the plate and remove the tested fruit for easy placement of the next fruit to be tested.

[0029] Further as Figure 4 As shown, it is worth noting that a rubber pad 107 is attached and fixed to the side of the clamping plate 106 away from the connecting rod 105. The area of ​​the rubber pad 107 is equal to the area of ​​the side of the clamping plate 106. In actual operation, the rubber pad 107 effectively increases the friction of the clamping plate 106 in clamping the fruit, thereby further improving the stability of the fruit clamping and fixing.

[0030] Further as Figure 2 and Figure 3 As shown, it is worth noting that an end plate 111 is fixed on one end of the threaded rod 109 located outside the second connecting cylinder 108, and a rubber sleeve is fitted on the surface of the end plate 111. In actual operation, the threaded rod 109 can be easily rotated by the end plate 111, which facilitates operation. The rubber sleeve increases the friction of rotating the end plate 111 and prevents slippage.

[0031] In summary: The clamping assembly 1 clamps the fruit at multiple points, which helps to evenly distribute pressure, thus fixing fruits of different shapes while improving the stability of the fruit clamping. Compared to other methods, it has better clamping stability and a wider clamping range. After the test is completed, the positioning assembly 2 releases the lock of the placement plate 4, and the placement plate 4 is pulled. The placement plate 4 drives the bottom slider 11 to slide in the slide groove 10. The cooperation between the slide groove 10 and the bottom slider 11 limits and guides the movement of the placement plate 4, so that the placement plate 4 can be pulled out from directly below the hardness tester 8, making it easier to remove the tested fruit and place the next fruit for testing. It is more convenient to place the fruit and facilitate testing. The end plate 111 makes it easy to rotate the threaded rod 109, which is convenient to operate. The rubber sleeve increases the friction of rotating the end plate 111 to prevent slippage. The rubber pad 107 effectively increases the friction of the clamping plate 106 on the fruit, further improving the stability of the fruit clamping.

[0032] The hardness tester 8 can be purchased from the market. The hardness tester 8 is equipped with a power supply. This is a mature technology in the field and has been fully disclosed. Therefore, it will not be repeated in the specification.
