Description

Technical Field

[0001] This utility model relates to the field of food testing equipment technology, specifically a sample fixing station for detecting the moisture content of food. Background Technology

[0002] Moisture content in food is a key indicator for measuring food quality, stability, and safety. Food moisture is the sum of free and bound water in food, and its content directly affects the freshness, shelf life, and processing performance of food.

[0003] However, existing technologies still have many shortcomings in practical applications. For example, in food production, it is necessary to analyze the stability of the production process by comparing the moisture data of different batches of samples. If the fixed platform is not convenient for batch testing, different batches of samples will show differences in testing at different times and by different operators, resulting in more unqualified products. At the same time, if the fixed platform is not convenient for clamping and positioning, the sample is prone to displacement during the testing process. Samples that are not effectively clamped will fall off directly during the testing process, affecting the detection of food moisture content and thus having low practicality.

[0004] To address the aforementioned problems, the inventors have proposed a sample fixing stage for detecting the moisture content of food. Utility Model Content

[0005] To address the problems of inconvenience in batch testing of food moisture content and inconvenience in clamping and positioning food samples, the purpose of this utility model is to provide a sample fixing stage for food moisture content testing.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a sample fixing stage for food moisture content detection, comprising a table surface, a plurality of clamping components evenly distributed are fixedly connected to the center of the top surface of the table surface, and sliding components are fixedly connected to both sides of the top surface of the table surface. The sliding components include two symmetrically distributed fixing plates, the bottom surfaces of the fixing plates are fixedly connected to the table surface, and the top surfaces of the fixing plates are provided with through grooves. A lead screw is rotatably connected to the inner walls of both sides of one of the through grooves. A first motor is fixedly connected to the upper part of one side of one of the fixing plates, and the output end of the first motor extends into the fixing plate and is fixedly connected to the lead screw. A first guide rod is fixedly connected to the inner walls of both sides of the other through groove. A bracket is slidably connected to the inner walls of the two through grooves. A control panel is fixedly connected to the top surface of the bracket, and a detection component is fixedly connected to the bottom surface of the bracket.

[0007] As a preferred technical solution of this application, the clamping assembly includes a housing, with bidirectional threaded rods rotatably connected to the middle of the inner walls on both sides of the housing, a second motor fixedly connected to one side of the housing, the output end of the second motor extending into the housing and fixedly connected to the bidirectional threaded rods, two second guide rods symmetrically fixedly connected to the inner walls on both sides of the housing, two sliding plates slidably connected inside the housing, the sliding plates being threadedly engaged with the bidirectional threaded rods, the sliding plates being movably engaged with the second guide rods, a connecting plate fixedly connected to the top surface of the sliding plates, and symmetrically provided grooves on the top surface of the housing for use with the connecting plate, and a clamping frame fixedly connected to the top surface of the connecting plate.

[0008] The above technical solution involves placing the sample to be tested between the clamping frames of the clamping assembly, starting the second motor, and transmitting power from its output end to the connected bidirectional threaded rod. This causes the bidirectional threaded rod to rotate between the inner walls of both sides of the housing. Since the two sliding plates are threaded onto the opposite thread directions engraved on the outer surface of the bidirectional threaded rod, and the sliding plates are movably connected to the second guide rod, the rotation of the bidirectional threaded rod will cause the two sliding plates to move relative to each other along the second guide rod. The limiting blocks at both ends of the sliding plates will slide along the limiting grooves on both sides of the housing, playing a limiting and guiding role to prevent the sliding plates from deviating during sliding. The connecting plate drives the clamping frames to move synchronously until the two clamping frames are tightly fitted to the sample surface, which can effectively and stably clamp and position the food sample.

[0009] As a preferred technical solution of this application, the bottom surface of the platform is fixedly connected with a plurality of support legs arranged in a rectangular array.

[0010] The above technical solution ensures the stability of the entire device, further guaranteeing the stability of the testing process.

[0011] As a preferred technical solution of this application, one side of the bracket is threadedly connected to the lead screw, and the other side of the bracket is movably connected to the first guide rod.

[0012] With the above technical solution, when the lead screw rotates, it will drive the bracket to slide smoothly along the through groove and the first guide rod.

[0013] As a preferred technical solution of this application, the lower part of the bracket is in contact with the inner wall of the through groove.

[0014] With the above technical solution, the support will be more stable when sliding.

[0015] As a preferred technical solution of this application, both ends of the slide are fixedly connected to limit blocks, and the two sides of the shell are provided with limit grooves for use with the limit blocks.

[0016] With the above technical solution, the limiting blocks at both ends of the skateboard will slide along the limiting grooves on both sides of the shell, playing a limiting and guiding role and preventing the skateboard from deviating when sliding.

[0017] As a preferred technical solution of this application, the two slide plates are respectively threaded onto the opposite thread directions engraved on the outer surface of the bidirectional threaded rod.

[0018] With the above technical solution, when the bidirectional threaded rod rotates, it will drive the two slide plates to move relative to each other along the second guide rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model can achieve the purpose of effectively detecting the moisture content of food samples in batches by rotating the lead screw, which will drive the bracket to slide smoothly along the through groove and the first guide rod. The detection component fixedly connected to the bottom of the bracket will move synchronously with the bracket.

[0021] 2. When the bidirectional threaded rod rotates, it drives two sliding plates to move relative to each other along the second guide rod. The limiting blocks at both ends of the sliding plates slide along the limiting grooves on both sides of the shell, which plays a limiting and guiding role and prevents the sliding plates from deviating when sliding. The connecting plate drives the clamping frame to move synchronously until the two clamping frames are tightly attached to the sample surface, thereby achieving the purpose of effectively and stably clamping and positioning the food sample.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Figure 1-4 As shown, this utility model provides a sample fixing stage for food moisture content detection, including a table surface 1, a plurality of support legs 4 arranged in a rectangular array fixedly connected to the bottom surface of the table surface 1, a plurality of clamping components 3 arranged at equal intervals fixedly connected to the center of the top surface of the table surface 1, and sliding components 2 fixedly connected to both sides of the top surface of the table surface 1.

[0030] The sliding assembly 2 includes two symmetrically distributed fixed plates 21. The bottom surface of the fixed plates 21 is fixedly connected to the platform 1. The top surface of the fixed plates 21 is provided with a through groove 22. A lead screw 23 is rotatably connected to the inner walls on both sides of one of the through grooves 22. A first motor 24 is fixedly connected to the upper part of one side of one of the fixed plates 21. The output end of the first motor 24 extends into the fixed plate 21 and is fixedly connected to the lead screw 23. A first guide rod 25 is fixedly connected to the inner walls on both sides of the other through groove 22. A bracket 26 is slidably connected to the inner walls of the two through grooves 22. One side of the bracket 26 is threadedly connected to the lead screw 23, and the other side of the bracket 26 is movably connected to the first guide rod 25. The lower part of the bracket 26 is in contact with the inner wall of the through groove 22. A control panel 27 is fixedly connected to the top surface of the bracket 26, and a detection assembly 28 is fixedly connected to the bottom surface of the bracket 26.

[0031] When the lead screw 23 rotates, it will drive the bracket 26 to slide smoothly along the through groove 22 and the first guide rod 25. The detection component 28, which is fixedly connected to the bottom surface of the bracket 26, will move synchronously with the bracket 26.

[0032] The clamping assembly 3 includes a housing 31. A bidirectional threaded rod 32 is rotatably connected to the middle of the inner walls on both sides of the housing 31. A second motor 33 is fixedly connected to one side of the housing 31. The output end of the second motor 33 extends into the housing 31 and is fixedly connected to the bidirectional threaded rod 32. Two second guide rods 34 are symmetrically fixedly connected to the inner walls on both sides of the housing 31. Two sliding plates 35 are slidably connected inside the housing 31. The sliding plates 35 are threadedly engaged with the bidirectional threaded rod 32. The sliding plates 35 are movably engaged with the second guide rods 34. The two sliding plates 35 are respectively threadedly engaged with the opposite thread directions engraved on the outer surface of the bidirectional threaded rod 32. Limiting blocks 36 are fixedly connected to both ends of the sliding plates 35. Limiting grooves 37 that cooperate with the limiting blocks 36 are opened on both sides of the housing 31. A connecting plate 38 is fixedly connected to the top surface of the sliding plates 35. A sliding groove 39 that cooperates with the connecting plate 38 is symmetrically opened on the top surface of the housing 31. A clamping frame 30 is fixedly connected to the top surface of the connecting plate 38.

[0033] When the bidirectional threaded rod 32 rotates, it will drive the two slide plates 35 to move relative to each other along the second guide rod 34. The connecting plate 38 drives the clamping frame 30 to move synchronously until the two clamping frames 30 are in close contact with the sample surface.

[0034] The working principle of a sample fixing stage for food moisture content detection according to an embodiment of this application is as follows: When it is necessary to detect the moisture content of a food sample, the sample to be tested is first placed between the clamping frames 30 of the clamping assembly 3. The second motor 33 is started, and its output end transmits power to the bidirectional threaded rod 32 connected to it, causing the bidirectional threaded rod 32 to rotate between the inner walls of the two sides of the housing 31. Since the two sliding plates 35 are respectively threaded onto the opposite thread directions engraved on the outer surface of the bidirectional threaded rod 32, and the sliding plates 35 are movably connected to the second guide rod 34, when the bidirectional threaded rod 32 rotates, it will drive the two sliding plates 35 to move relative to each other along the second guide rod 34. The limiting blocks 36 at both ends of the sliding plates 35 will slide along the limiting grooves 37 on both sides of the housing 31, playing a limiting and guiding role to prevent the sliding plates 35 from deviating when sliding. The connecting plate 38 drives the clamping frames 30 to move synchronously until the two clamping frames 30 are tightly attached to the sample surface, thereby achieving the purpose of effectively and stably clamping and positioning the food sample.

[0035] Once the sample is fixed, the first motor 24 is started, and its output end transmits power to the lead screw 23 connected to it, causing the lead screw 23 to rotate inside the through groove 22 of one of the fixed plates 21. Since one side of the bracket 26 is threadedly connected to the lead screw 23 and the other side is movably connected to the first guide rod 25 in another through groove 22, and the lower part of the bracket 26 is in contact with the inner wall of the through groove 22, when the lead screw 23 rotates, it will drive the bracket 26 to slide smoothly along the through groove 22 and the first guide rod 25. The detection component 28 fixedly connected to the bottom surface of the bracket 26 will move synchronously with the bracket 26, thereby achieving the purpose of effectively detecting the moisture content of food samples in batches.

[0036] The support legs 4 on the bottom of the table 1 ensure the stability of the entire device and further guarantee the stability of the testing process.
