Description

Technical Field

[0001] This invention relates to the field of testing device technology, specifically to a quality testing device for beef sauce products. Background Technology

[0002] The beef sauce product quality testing device is an automated quality screening system for unbottled beef sauce produced after production. It mainly consists of four modules: automatic feeding, sensory testing, physicochemical testing, and microbial early warning. It precisely transports sauce samples via an insulated conveyor belt. Then, using an automatic sampling needle and a rapid detection chip, it measures the salt, moisture, and oil content. Simultaneously, an ATP fluorescence detector screens for microbial contamination risks. Finally, based on the summarized test results, a diversion valve sends qualified sauce to the bottling stage, while unqualified sauce is discharged into a waste bin. The entire process requires no manual contact and can complete single-sample testing within three minutes, ensuring both testing accuracy and efficiency while enabling data traceability, thereby controlling the quality of the beef sauce product.

[0003] However, the existing beef sauce testing equipment has a cumbersome testing process, making it difficult to quickly and efficiently test beef sauce. This not only prolongs the product testing time but also affects the production schedule, ultimately leading to a decrease in processing efficiency. Summary of the Invention

[0009] Furthermore, the sampling assembly includes two support plates fixedly connected to the top of the conveyor belt.

The driving component includes an electric push rod fixedly connected to the back of the corresponding support plate. The output end of the electric push rod passes through the corresponding support plate. The output end of the electric push rod is fixedly connected to the sliding plate. The output end of the electric push rod is slidably connected to the corresponding support plate.

[0010] Furthermore, the positioning component includes a sampling box disposed on the top of the conveyor belt. Two rectangular plates are fixedly connected to the top of the conveyor belt. Two sliding rods are fixedly connected to the side of the two rectangular plates that are close to each other. Two positioning plates are slidably connected to the outer walls of the two sliding rods. The side of the two positioning plates that are close to each other is in contact with the sampling box.

[0011] Furthermore, the drive assembly includes a bidirectional screw rotatably connected to two rectangular plates, the outer wall of the bidirectional screw being threadedly connected to two positioning plates, two knobs being fixedly connected to the outer wall of the bidirectional screw, and the bidirectional screw passing through the two positioning plates.

[0012] Furthermore, the lifting assembly includes a base plate disposed at the bottom of the conveyor belt. Several universal casters with brakes are rotatably connected to the bottom of the base plate. A U-shaped frame is fixedly connected to the top of the base plate. A self-locking motor is fixedly connected to the U-shaped frame. The output shaft of the self-locking motor is fixedly connected to a rotating shaft via a coupling. The rotating shaft passes through the U-shaped frame. A connecting rod is fixedly connected to the outer wall of the rotating shaft.

[0013] Furthermore, the limiting component includes a limiting rotating rod fixedly connected to the outer wall of the rotating shaft, and an insert rod is slidably connected to the limiting rotating rod.

[0014] Furthermore, the balancing assembly includes several sleeves fixedly connected to the top of the base plate, each sleeve having a slidably connected balance bar, the top ends of each balance bar being fixedly connected to the conveyor belt, and four sleeves and four balance bars are provided.

[0015] The present invention has the following beneficial effects:

[0016] 1. This invention, through the setting of a detection unit, after the sampling box is positioned, starts the conveyor belt to transport it directly below the two automatic sampling needles. Then the conveyor belt is turned off, and then electric push rod one is started. Guided by two slide rods two, it drives the sliding plate to move the automatic sampling needle into the sampling box to complete the sampling of beef sauce. After sampling, electric push rod one and slide rod two are reset. Then electric push rod two is started. Guided by two slide rods one, it drives the sliding plate to move the automatic sampling needle synchronously above the test strip and ATP fluorescence detector. After it is in position, electric push rod one and slide rod two are started again to move the sampling needle closer to the detection component. The sampled liquid is dripped into the test strip and the test tube of the ATP fluorescence detector respectively. The test strip can quickly and qualitatively detect the salt, moisture and oil content of the beef sauce. The fluorescence intensity of the ATP fluorescence detector is positively correlated with the number of bacteria in the sample. If the fluorescence value corresponds to more than 1000 bacteria per gram of beef sauce, it is determined that the risk of microbial contamination is high and bottling is prohibited. This setting can realize the rapid and synchronous detection of key quality indicators of beef sauce, improving efficiency and accuracy.

[0017] 2. By setting up a positioning part, when in use, the processed beef sauce sample is first collected through the sampling box and placed on the conveyor belt. Then, the knob on the outer wall of the bidirectional screw is rotated. The bidirectional screw will be guided by two slide bars and drive the two positioning plates on them to move closer or further apart, thereby achieving the positioning of the sampling box. This setting can ensure that the sampling box remains stable during the transportation and sampling process and avoid the impact of displacement on the detection accuracy.

[0018] 3. This invention, by setting up a lifting unit, allows for height adjustment based on operator height or site requirements. A self-locking motor can be activated, driving connecting rod one to rotate via a rotating shaft. Since connecting rod one is hinged to connecting rod two, and the other end of connecting rod two is hinged to the U-shaped frame two at the bottom of the conveyor belt, rotation of connecting rod one, through the transmission between connecting rod two and the U-shaped frame two, raises and lowers the conveyor belt to a suitable height. After height adjustment, inserting rods into the corresponding insertion holes of the limiting rotating rod on the outer wall of the rotating shaft and the U-shaped frame one, achieves mechanical limiting of the rotating shaft, preventing accidental rotation that could cause conveyor belt displacement, and reducing the load on the self-locking motor. Furthermore, during conveyor belt lifting, multiple balance bars at the bottom slide synchronously along multiple sleeves on the top of the base plate, ensuring lifting stability. This design allows for flexible height adjustment to suit different scenarios and personnel needs, while ensuring safe and stable adjustment.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1 - Figure 8 As shown, the present invention is a quality testing device for beef sauce products, including a conveyor belt 1, and further including: a testing unit 2, which is disposed at the top of the conveyor belt 1; a positioning unit 3, which is disposed at the top of the conveyor belt 1; and a lifting unit 4, which is disposed at the bottom of the conveyor belt 1.

[0033] The detection unit 2 includes a detection component 21, which is disposed on top of the conveyor belt 1; and a sampling component 22, which is mounted on top of the detection component 21.The detection assembly 21 includes a detection platform 211 fixedly connected to the top of the conveyor belt 1. A pull-out frame 212 is fixedly connected to the top of the detection platform 211. A test strip 213 is slidably connected inside the pull-out frame 212. An ATP fluorescence detector 214 is fixedly connected to the top of the detection platform 211. A test tube 215 is slidably connected to the top of the ATP fluorescence detector 214. The test strip 213 and the ATP fluorescence detector 214 are symmetrically distributed on both sides of the detection platform 211. The sampling assembly 22 includes two support plates 221 fixedly connected to the top of the conveyor belt 1. Two slide rods 222 are fixedly connected to the side of the two support plates 221 that are close to each other. A sliding plate 223 is slidably connected to the outer wall of the two slide rods 222. Two sliding rods 224 are connected to the upper sliding plate 225, and two automatic sampling needles 226 are mounted on the sliding plate 225. An electric push rod 227 is fixedly connected to the top of the slide plate 223. The output end of the electric push rod 227 is fixedly connected to the sliding plate 225. A driving component is mounted on the corresponding support plate 221. The two automatic sampling needles 226 are respectively adapted to the test strip 213 and the ATP fluorescence detector 214. The driving component includes an electric push rod 228 fixedly connected to the back of the corresponding support plate 221. The output end of the electric push rod 228 passes through the corresponding support plate 221 and is fixedly connected to the slide plate 223. The output end of rod 228 is slidably connected to the corresponding support plate 221. By setting the detection unit 2, after the sampling box 311 is positioned, the conveyor belt 1 is started to transport the sampling box 311 directly below the two automatic sampling needles 226. Then, the conveyor belt 1 is turned off, and the electric push rod 227 is started. Guided by the two slide rods 224, it drives the sliding plate 225 to insert the two automatic sampling needles 226 into the sampling box 311 to complete the beef sauce sampling. After sampling, the electric push rod 227 resets in conjunction with the slide rods 224. Then, the electric push rod 228 is started, guided by the two slide rods 222, which drives the sliding plate 223 to move the two automatic sampling needles 226 synchronously to the test strip 213 and the ATP fluorescence. Directly above the detector 214, after being moved into position, the electric push rod 227 is activated again in conjunction with the slide rod 224, causing the automatic sampling needle 226 to approach the detection component. The sampled liquid is then dripped into the test strip 213 and the test tube 215 of the ATP fluorescence detector 214, respectively. The test strip 213 can quickly and qualitatively detect the salt, moisture, and fat content in the beef sauce. The fluorescence intensity of the ATP fluorescence detector 214 is positively correlated with the number of bacteria in the sample. When the fluorescence value exceeds the set standard, such as >1000 bacteria per gram of beef sauce, the sample is deemed to have a high risk of microbial contamination and bottling is prohibited. This setting enables rapid and simultaneous detection of key quality indicators of beef sauce, improving detection efficiency and accuracy.

The positioning assembly 31 includes a sampling box 311 disposed on the top of the conveyor belt 1. Two rectangular plates 312 are fixedly connected to the top of the conveyor belt 1. Two sliding rods 313 are fixedly connected to the sides of the two rectangular plates 312 that are close to each other. Two positioning plates 314 are slidably connected to the outer walls of the two sliding rods 313. The sides of the two positioning plates 314 that are close to each other are in contact with the sampling box 311. The driving assembly 32 includes a bidirectional screw 321 rotatably connected to the two rectangular plates 312. The outer wall of the double-sided screw 321 is threadedly connected to two positioning plates 314. Two knobs 322 are fixedly connected to the outer wall of the double-sided screw 321. The double-sided screw 321 passes through the two positioning plates 314. By setting the positioning part 3, when in use, the processed beef sauce sample is first collected through the sampling box 311 and placed on the conveyor belt 1. Then, the knobs 322 on the outer wall of the double-sided screw 321 are rotated. The double-sided screw 321 will be guided by the two sliding rods 313 and drive the two positioning plates 314 on it to move closer or further away from each other to achieve the positioning of the sampling box 311. Through this setting, it can be ensured that the sampling box 311 remains stable during the conveying and sampling process, and avoid displacement affecting the detection accuracy.

[0035] The lifting unit 4 includes a lifting assembly 41, which is disposed at the bottom of the conveyor belt 1; a limiting assembly 42, which is disposed on the lifting assembly 41; and a balancing assembly 43, which is disposed at the bottom of the conveyor belt 1. The lifting assembly 41 includes a base plate 411 disposed at the bottom of the conveyor belt 1. Several universal casters 412 with brakes are rotatably connected to the bottom of the base plate 411. A U-shaped frame 413 is fixedly connected to the top of the base plate 411. A self-locking motor 414 is fixedly connected to the U-shaped frame 413. The output shaft of the self-locking motor 414 is fixedly connected to a rotating shaft 415 through a coupling. The rotating shaft 415 passes through the U-shaped frame 413. A connecting rod 4 is fixedly connected to the outer wall of the rotating shaft 415. 16. Connecting rod 416 is hinged to connecting rod 417 at the end away from the rotating shaft 415. U-shaped frame 418 is fixedly connected to the bottom of conveyor belt 1. Connecting rod 417 is hinged to U-shaped frame 418 at the end away from connecting rod 416. The outer wall of rotating shaft 415 is rotatably connected to U-shaped frame 413. Limiting assembly 42 includes limiting rotating rod 421 fixedly connected to the outer wall of rotating shaft 415. Inserting rod 422 is slidably connected to limiting rotating rod 421. Several inserting rod holes 423 are opened on the left side of U-shaped frame 413. The right end of inserting rod 422 extends into the corresponding inserting rod hole 423. Balancing assembly 43 includes several sleeves 431 fixedly connected to the top of base plate 411. Several sleeves 431 Each sleeve 431 is slidably connected with a balance bar 432. The top ends of several balance bars 432 are fixedly connected to the conveyor belt 1. There are four sleeves 431 and four balance bars 432. By setting up a lifting part 4, if the height of the device needs to be adjusted according to the height of the operator or the needs of the site during use, the self-locking motor 414 can be started. The self-locking motor 414 will drive the connecting rod 1 416 to rotate through the rotating shaft 415. Since the connecting rod 1 416 is hinged to the connecting rod 2 417, and the other end of the connecting rod 2 417 is hinged to the U-shaped frame 2 418 at the bottom of the conveyor belt 1, the conveyor belt can be driven by the transmission action of the connecting rod 2 417 and the U-shaped frame 2 418 during the rotation of the connecting rod 1 416. 1. After the height is adjusted to a suitable height, the insertion rod 422 can be inserted into the corresponding insertion rod hole 423 on the outer wall limiting rod 421 of the rotating shaft 415 and the U-shaped frame 413 to achieve mechanical limiting of the rotating shaft 415, preventing accidental rotation that could cause displacement of the conveyor belt 1. This also reduces the load pressure on the self-locking motor 414. In addition, during the lifting process of the conveyor belt 1, the multiple balance rods 432 at its bottom will also slide synchronously along the multiple sleeves 431 at the top of the base plate 411, thereby ensuring the stability of the conveyor belt 1 during the lifting process. Through this setting, the height of the device can be flexibly adjusted to suit different usage scenarios and operator needs, while ensuring the safety and stability of the adjustment process.

[0036] The ATP fluorescence detector 214 is a rapid detection device based on ATP biofluorescence technology. It uses luciferase to catalyze the reaction of ATP contained in microorganisms in beef sauce to produce fluorescence, and then detects the fluorescence intensity in RLU units to indirectly determine the degree of microbial contamination in the sauce. It is suitable for microbial screening at the production site of unbottled beef sauce. Recommended model: CAI-ATP-0701T, which can store 80,000 data points and is suitable for batch testing scenarios.

[0037] Self-locking motor 414: These are special motors that are equipped with worm gears and other structures. The core function is to automatically lock the output shaft after power failure through mechanical or circuit design. This prevents the load from moving on its own and does not require an additional braking device. Recommended model: 24V voltage PGM.W050 series, with a self-locking force of over 80kg and no slippage even after 24 hours of stationary operation.

[0038] It should be noted that the control of the conveyor belt 1, ATP fluorescence detector 214, automatic sampling needle 226, electric push rod one 227, electric push rod two 228 and self-locking motor 414 in this application can all be achieved by using the program set in the control panel and inputting relevant parameters as needed for automated control. The setting of this control method can be realized by existing technologies, such as PLC.

[0039] In use, the processed beef sauce sample is first collected through the sampling box 311 and placed on the conveyor belt 1. Then, the knob 322 on the outer wall of the bidirectional screw 321 is rotated. The bidirectional screw 321, guided by the two slide bars 313, drives the two positioning plates 314 on it to move closer or further apart to position the sampling box 311. This setting ensures that the sampling box 311 remains stable during conveying and sampling, avoiding displacement that could affect the detection accuracy. After the sampling box 311 is positioned, the conveyor belt 1 is started to transport the sampling box 311 directly below the two automatic sampling needles 226. Then, the conveyor belt 1 is turned off, and the electric push rod 227 is started. Guided by the two slide bars 224, it drives the sliding plate 225 to move the two automatic sampling needles. The needle 226 is inserted into the sampling box 311 to complete the sampling of the beef sauce. After sampling, the electric push rod 227 and the slide rod 224 are reset. Then, the electric push rod 228 is activated, which, guided by the two slide rods 222, drives the slide plate 223 to move the two automatic sampling needles 226 synchronously to directly above the test strip 213 and the ATP fluorescence detector 214. After they are in position, the electric push rod 227 and the slide rod 224 are activated again to bring the automatic sampling needles 226 closer to the detection components, and the sampled liquid is dripped into the test tubes 215 of the test strip 213 and the ATP fluorescence detector 214, respectively. The test strip 213 can quickly and qualitatively detect the salt, water and fat content in the beef sauce, while the ATP fluorescence detector 214... The fluorescence intensity is positively correlated with the number of bacteria in the sample. When the fluorescence value exceeds the set standard, such as >1000 bacteria per gram of beef sauce, the sample is deemed to have a high risk of microbial contamination and bottling is prohibited. This setting enables rapid and simultaneous detection of key quality indicators of beef sauce, improving detection efficiency and accuracy. If the device height needs to be adjusted according to the operator's height or on-site requirements during use, the self-locking motor 414 can be activated. The self-locking motor 414 will drive the connecting rod 416 to rotate through the rotating shaft 415. Since the connecting rod 416 is hinged to the connecting rod 417, and the other end of the connecting rod 417 is hinged to the U-shaped frame 418 at the bottom of the conveyor belt 1, during the rotation of the connecting rod 416, the connecting rod 417 and the U-shaped frame can be connected. The transmission action of the second 418 drives the conveyor belt 1 to rise and fall to a suitable height. After the height adjustment is completed, the insertion rod 422 can be inserted into the corresponding insertion rod hole 423 on the outer wall limiting rotating rod 421 of the rotating shaft 415 and the U-shaped frame 413 to achieve mechanical limiting of the rotating shaft 415, preventing it from rotating accidentally and causing the conveyor belt 1 to shift. At the same time, it can also reduce the load pressure on the self-locking motor 414. In addition, during the lifting and lowering process of the conveyor belt 1, the multiple balance rods 432 at the bottom of the conveyor belt 1 will also slide synchronously along the multiple sleeves 431 at the top of the base plate 411, thereby ensuring the stability of the conveyor belt 1 during the lifting and lowering process. Through this setting, the height of the device can be flexibly adjusted to adapt to different usage scenarios and operator needs, and the safety and stability of the adjustment process can be guaranteed.
