Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and more specifically, to a sample mixing device for food testing. Background Technology

[0002] Sample mixing devices for food testing are key equipment in modern food testing processes. They are primarily used to ensure the uniform mixing of samples with different components, thereby improving the representativeness and accuracy of test results. With the diversification of food types and processing techniques, sample mixing device technology has continuously evolved, employing advanced mechanical, airflow, and vibration mixing technologies to enable different types of food samples (such as solids, liquids, and powders) to achieve an ideal homogeneous state in a short time. These devices are typically equipped with intelligent control systems that automatically adjust mixing parameters based on sample characteristics, ensuring the accuracy of the mixing effect.

[0003] While some existing mixing devices employ mechanical shaking, most of these devices achieve mixing by shaking in one direction. Since some food samples contain solid particles, shaking in one direction alone cannot fully mix these samples. Insufficiently mixed samples may affect subsequent testing. Therefore, we propose a sample mixing device for food testing. Utility Model Content

[0004] The purpose of this invention is to provide a sample mixing device for food testing, in order to solve the problem that some food samples contain solid particles, and these samples cannot be fully mixed by shaking in one direction. Insufficiently mixed samples may affect subsequent testing.

[0005] To achieve the above objectives, a sample mixing device for food testing is provided, including a base, a vertical plate fixedly connected to one side of the upper surface of the base, a sample mixing container installed on the lower surface of the top of the vertical plate, a reserved groove provided on the upper surface of the base below the vertical plate, and a shaking component provided on both the reserved groove and the upper surface of the base.

[0006] As a further improvement to this technical solution, the shaking assembly includes a drive motor installed on the bottom surface inside the reserved slot, a rotating rod installed on the output end of the drive motor, a first bevel gear fixedly connected to the bottom outer wall of the rotating rod, and two first protrusions fixedly connected to the upper end of the rotating rod above the first bevel gear.

[0007] As a further improvement to this technical solution, a second bevel gear is meshed with one side of the first bevel gear, and a connecting rod is fixedly connected to the center of the second bevel gear. The connecting rod passes through the vertical plate and extends to the outside of the vertical plate. Two second protrusions are fixedly connected to the connecting rod, and a bearing is fixedly connected to the end of the connecting rod located on the outside of the vertical plate.

[0008] As a further improvement to this technical solution, a first spring is installed on the top surface of the sample mixing barrel, and the top end of the first spring is connected to the upright plate. A second spring is installed on the side of the sample mixing barrel near the inner side of the upright plate, and the second spring is connected to the inner side of the upright plate.

[0009] As a further improvement to this technical solution, the bottom and side surfaces of the sample mixing tank are fixedly connected to an L-shaped plate. The bottom surface of the L-shaped plate abuts against two second protrusions, and the outer surface of the L-shaped plate abuts against two first protrusions. The outer surfaces of both ends of the L-shaped plate are provided with soft pads.

[0010] As a further improvement to this technical solution, a feed inlet is inserted through the front side of the sample mixing tank, and the feed inlet is inclined. A sealing cap is provided on the top of the feed inlet, and a handle is provided on the sealing cap.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this food testing sample mixing device, the shaking component is designed and used. Driven by a motor, the first protrusion on the rotating rod shakes the food testing sample in the sample mixing tank horizontally, while the second protrusion on the connecting rod shakes the sample vertically. The mechanical shaking in two different directions makes the various solid and liquid samples more thoroughly and evenly mixed, improving the mixing effect and reducing the impact on subsequent testing.

[0022] Example 1

[0023] Please see Figures 1-4 As shown, the purpose of this embodiment is to provide a sample mixing device for food testing, including a base 1, a vertical plate 11 fixedly connected to one side of the upper surface of the base 1, a sample mixing tank 3 installed on the lower surface of the top of the vertical plate 11, a reserved groove 12 opened on the upper surface of the base 1 below the vertical plate 11, and a shaking component 2 provided on both the reserved groove 12 and the upper surface of the base 1. The reserved groove 12 provides an installation environment for the device and improves the rationality of the structure.

[0024] In addition, a second bevel gear 25 is meshed with one side of the first bevel gear 22. A connecting rod 27 is fixedly connected to the center of the second bevel gear 25. The connecting rod 27 passes through the vertical plate 11 and extends to the outside of the vertical plate 11. Two second protrusions 26 are fixedly connected to the connecting rod 27. A bearing 28 is fixedly connected to the end of the connecting rod 27 located on the outside of the vertical plate 11. By setting the bearing 28, the connecting rod 27 can rotate on the vertical plate 11 and remain stable, ensuring the normal realization of rotation.

[0025] Furthermore, an L-shaped plate 32 is fixedly connected to the bottom and sides of the sample mixing container 3. The bottom surface of the L-shaped plate 32 abuts against two second protrusions 26, and the outer surface of the L-shaped plate 32 abuts against two first protrusions 24. A soft pad 33 is provided on the outer surface of both ends of the L-shaped plate 32. This arrangement allows the convex portions of the first protrusions 24 and second protrusions 26 to contact the L-shaped plate 32. This results in corresponding shaking; by setting up the soft pad 33, the L-shaped plate 32 may collide with the rigid parts, reducing the wear at the end of the L-shaped plate 32 and extending the service life of the L-shaped plate 32; the front side of the sample mixing tank 3 is provided with a feed inlet 35, which is inclined, and the top of the feed inlet 35 is covered with a sealing cover 36, which is provided with a handle. The handle makes it convenient for users to use and enhances the practicality of the device; by setting up the sealing cover 36, the sample is prevented from spilling when the sample mixing tank 3 shakes.

[0026] The working principle of this solution is as follows: The user can first open the sealing cover 36 by pulling the handle diagonally upwards, and then introduce the sample for testing into the sample mixing tank 3 through the feed port 35. After that, the sealing cover 36 is closed again on the feed port 35. The drive motor 21 is started, and the output end of the drive motor 21 rotates, which drives the rotating rod 23 to rotate. The rotating rod 23 drives the first bevel gear 22 to rotate, and the first bevel gear 22 simultaneously drives the first protrusion 24 to rotate. The first protrusion 24 contacts the outer wall of the side of the L-shaped plate 32. Due to its convex part, it generates a horizontal squeezing force on the side of the vertical plate 11. The sample mixing tank 3 is thus driven by the L-shaped plate 32 to move in the same direction. The second spring 34 connected to the sample mixing tank 3 is compressed at this time. When the first protrusion 24 rotates to another part and contacts the outer side of the L-shaped plate 32 again, the sample mixing tank 3 deforms due to its own elasticity. The reset generates elastic force, pushing the pulled sample mixing barrel 3 back to its original position, i.e., pushing it in the opposite direction to the upright plate 11. This back-and-forth movement generates horizontal swaying. The first bevel gear 22 rotates, driving the meshing second bevel gear 25 to rotate. The second bevel gear 25 drives the connecting rod 27 at the center to rotate, which in turn drives the second protrusion 26 fixedly connected to it to rotate. When the second protrusion 26 contacts the L-shaped plate 32 through its convex part, it will push up the L-shaped plate 32. The L-shaped plate 32 will push the sample mixing barrel 3 upward, and the first spring 31 connected to the top surface of the sample mixing barrel 3 will be compressed. When the non-convex part of the second protrusion 26 abuts against the bottom surface of the L-shaped plate 32 again, the sample mixing barrel 3 will move downward briefly under gravity. This process repeats, generating vertical swaying. The horizontal and vertical swaying ensures that the sample is fully mixed.
