Description

Technical Field

[0001] This utility model relates to the field of food contact material testing technology, and in particular to a multi-environment simulation pretreatment test machine for food contact materials. Background Technology

[0002] Currently, microplastic and nanoplastic pollution has become a research focus as emerging pollutants. Food contact materials, due to the widespread use of plastics, are a significant source of microplastics and nanoplastics in food, entering the human body through ingestion and posing a serious threat to health. Studies have shown that temperature, steam, external mechanical force, and photoaging are the main causes of wear and peeling of food contact materials, leading to the generation of microplastics and nanoplastics. In existing technologies, the pretreatment schemes for detecting microplastics and nanoplastics in food contact materials typically examine the effects of solvent properties, temperature, mechanical force, steam, and light aging test conditions on the leaching of microplastics and nanoplastics based on the sample material characteristics. Then, different separation and enrichment methods are adopted according to particle size, followed by concentration, separation, and relevant detection and analysis. In practice, this requires multiple changes to sample containers, experimental equipment, and experimental conditions, resulting in cumbersome operation procedures and low efficiency. Therefore, there is an urgent need for a pretreatment testing machine that can integrate various environmental conditions that food contact materials may encounter during food storage, transportation, and use to solve the above problems and facilitate further safety assessments of these food contact materials. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a multi-environment simulation pretreatment testing machine for food contact materials. This machine can examine the effect of a single environmental condition on the leaching of microplastics and nanoplastics in food contact materials, and can also simultaneously simulate the combined effects of multiple environmental conditions, providing convenience for further safety assessment of the food contact material.

[0004] The food contact material multi-environment simulation pretreatment test machine according to an embodiment of the present invention includes a frame, a vibration device, a loading box, a hot air generator, a steam generator, and a gripping robot.

[0005] The frame is provided with a first test chamber, a second test chamber, and a third test chamber, arranged sequentially from top to bottom and interconnected. The third test chamber is used to contain solvent. A vibration device is mounted on the frame, and a loading box is used to contain the sample. The vibration device is used to drive the loading box to vibrate so that the inner wall of the loading box collides with the sample. A hot air generator is mounted on the frame to generate hot air flowing in the first test chamber. A steam generator is mounted on the frame to generate steam flowing in the second test chamber. A gripping robot is mounted on the frame to grip the sample in the loading box and drive the sample to move sequentially into the first, second, and third test chambers.

[0006] It has at least the following beneficial effects:

[0007] When researchers need to perform multi-environment simulation pretreatment on samples, the sample to be tested can be placed in the loading box. The vibration device is then activated, causing the loading box to vibrate. The inner wall of the loading box continuously collides with the sample, simulating the external mechanical forces experienced by food contact materials during storage or transportation. This induces the initial leaching of microplastics and nanoplastics under the influence of mechanical forces. After the mechanical force simulation is complete, the gripping robot is activated to precisely grasp the sample that has undergone preliminary vibration treatment in the loading box. Since the first, second, and third test chambers on the frame are arranged sequentially from top to bottom and interconnected, a smooth channel is provided for the gripping robot to move the sample. The gripping robot can directly move the sample from top to bottom into the first test chamber. Subsequently, the hot air generator starts working, continuously circulating hot air within the first test chamber. The sample is subjected to the hot air in the first test chamber, simulating the use of food contact materials in high-temperature environments. At this point, the influence of temperature on the leaching of microplastics and nanoplastics in the sample is demonstrated. After the hot air environment simulation in the first test chamber is completed, the gripping robot continues to move the sample downwards, allowing the sample to enter the second test chamber from the first test chamber. Next, the steam generator is activated, filling the second test chamber with flowing steam. The sample is subjected to the effects of the steam environment, simulating the use of food contact materials in a steam environment. The influence of steam on the leaching of microplastics and nanoplastics is thus revealed.

[0008] After the steam environment simulation is completed, the gripping robot continues to move the sample downwards, allowing it to enter the third test chamber from the second. Since the third test chamber contains solvent (commonly a food-grade styrofoam), the sample will come into contact with the solvent upon entering, simulating the usage scenario of food contact materials in contact with solvents. The influence of solvent properties on the leaching of microplastics and nanoplastics is also included in the simulation. After the solvent environment simulation is completed, the gripping robot moves upwards with the sample and sequentially extracts it from the third, second, and first test chambers. Finally, the gripping robot places the sample back into the loading box for the experimenter to retrieve, completing the multi-environment simulation pretreatment of the sample. This multi-environment simulation pretreatment test machine for food contact materials integrates multiple environmental conditions such as temperature, steam, mechanical force, and solvents, enabling simultaneous simulation of the comprehensive effects of food contact materials in various usage scenarios. It solves the problems of cumbersome operation and low efficiency caused by examining a single condition separately in existing technologies, more closely resembling the actual usage of food contact materials. This helps to more comprehensively evaluate the safety of food contact materials and provides more reliable pretreated samples for subsequent testing and analysis.

[0009] According to the food contact material multi-environment simulation pretreatment test machine of this utility model embodiment, the vibration device is a vibration conveyor. The vibration conveyor is located behind the first test chamber. The vibration conveyor is used to transport the loading box from back to front and drive the loading box to vibrate, so that the gripping robot can grip the sample in the loading box at the front end of the vibration conveyor.

[0010] The food contact material multi-environment simulation pretreatment test machine according to an embodiment of the present utility model further includes a cover, which is disposed on the frame, and the vibrating conveyor, the hot air generator, the steam generator, the gripping manipulator, the first test chamber, the second test chamber and the third test chamber are all disposed inside the cover.

[0011] According to the food contact material multi-environment simulation pretreatment test machine of this utility model embodiment, the cover is provided with upper and lower feeding ports, which are correspondingly arranged with the rear end of the vibrating conveyor, and the upper and lower feeding ports are used for the material box to pass through.

[0012] According to the food contact material multi-environment simulation pretreatment test machine of this utility model embodiment, the cover is provided with an observation window.

[0013] According to an embodiment of the present invention, a multi-environment simulation pretreatment test machine for food contact materials further includes multiple xenon arc lamps, all of which are disposed inside the housing and on the top wall of the housing. The xenon arc lamps are used to simulate aging under natural light irradiation.

[0014] The food contact material multi-environment simulation pretreatment test machine according to an embodiment of the present invention further includes multiple ultraviolet lamps, all of which are disposed inside the housing and on the top wall of the housing. The ultraviolet lamps are used to simulate ultraviolet light irradiation aging.

[0015] The food contact material multi-environment simulation pretreatment test machine according to an embodiment of the present invention further includes a heating device, which is disposed in the third test chamber and is used to heat the solvent in the third test chamber.

[0016] According to the food contact material multi-environment simulation pretreatment test machine of the present invention, the filling box is made of metal or glass.

[0027] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] refer to Figure 1 and Figure 2 This utility model discloses a multi-environment simulation pretreatment test machine for food contact materials, including a frame 100, a vibration device 200, a loading box 210, a hot air generator (not shown in the figure), a steam generator (not shown in the figure), and a gripping robot 300.

[0031] The frame 100 is provided with a first test chamber 110, a second test chamber 120, and a third test chamber 130, which are arranged sequentially from top to bottom and are interconnected. The third test chamber 130 is used to contain solvent. A vibration device 200 is provided on the frame 100, and a loading box 210 is used to contain the sample. The vibration device 200 is used to drive the loading box 210 to vibrate, thereby causing the loading box to vibrate. The inner wall of chamber 210 collides with the sample; a hot air generator is mounted on frame 100 to generate hot air flowing in the first test chamber 110; a steam generator is mounted on frame 100 to generate steam flowing in the second test chamber 120; a gripping robot 300 is mounted on frame 100 to grip the sample in chamber 210 and drive the sample sequentially into the first test chamber 110, the second test chamber 120, and the third test chamber 130. It should be noted that in this embodiment of the invention, the sample refers to food contact material.

[0032] Understandably, when researchers need to perform multi-environment simulation pretreatment on samples, they can first place the sample to be tested into the loading box 210. At this time, the vibration device 200 is activated, driving the loading box 210 to vibrate. The inner wall of the loading box 210 will continuously collide with the sample, thereby simulating the external mechanical force exerted on food contact materials during storage or transportation, allowing the sample to initially show a tendency to leach microplastics and nanoplastics under the influence of mechanical force. After the mechanical force simulation is completed, the gripping robot 300 is activated to accurately grip the sample that has undergone preliminary vibration treatment in the loading box 210. Since the first test chamber 110, the second test chamber 120, and the third test chamber 130 on the frame 100 are arranged sequentially from top to bottom and are interconnected, this provides a smooth channel for the gripping robot 300 to move the sample. The gripping robot 300 directly moves the sample from top to bottom into the first test chamber 110. Then, the hot air generator activates, continuously circulating hot air within the first test chamber 110. The sample is subjected to the hot air within the first test chamber 110, simulating the use of food contact materials in a high-temperature environment. At this point, the influence of temperature on the leaching of microplastics and nanoplastics in the sample is demonstrated. After the hot air environment simulation in the first test chamber 110 is completed, the gripping robot 300 continues to move the sample downwards, allowing it to enter the second test chamber 120. Next, the steam generator activates, filling the second test chamber 120 with flowing steam. The sample is subjected to the steam environment, simulating the use of food contact materials in a steam environment. The influence of steam on the leaching of microplastics and nanoplastics is then revealed.

[0033] After the steam environment simulation is completed, the gripping robot 300 continues to move downwards with the sample, allowing it to enter the third test chamber 130 from the second test chamber 120. Since the third test chamber 130 contains solvent (commonly used food simulation liquid), the sample will come into contact with the solvent upon entering, simulating the usage scenario of food contact materials in contact with solvents. The influence of solvent properties on the leaching of microplastics and nanoplastics is also included in the simulation. After the solvent environment simulation is completed, the gripping robot 300 moves upwards with the sample and sequentially extracts it from the third test chamber 130, the second test chamber 120, and the first test chamber 110. Finally, the gripping robot 300 places the sample back into the loading box 210 for the experimenter to retrieve, thus completing the multi-environment simulation pretreatment of the sample. This multi-environment simulation pretreatment test machine for food contact materials integrates various environmental conditions such as temperature, steam, mechanical force, and solvents. It can examine the effect of a single environmental condition on the leaching of microplastics and nanoplastics in food contact materials, and can also simulate the combined effect of multiple environmental conditions at the same time. It solves the problems of cumbersome and inefficient existing operating procedures, and is closer to actual use conditions, providing convenience for further safety assessment of the food contact material.

[0034] In this embodiment of the invention, the filling box 210 is made of metal or glass. It is understood that using metal or glass for the filling box 210 avoids the generation of microplastics and nanoplastics due to vibration and collision, preventing interference with the detection of sample leachates. This ensures that microplastics and nanoplastics in the experiment originate only from food contact material samples, improving the accuracy of pretreatment and subsequent testing, and providing a reliable data basis for assessing material safety.

[0035] refer to Figure 1 The vibration device 200 is a vibrating conveyor, located behind the first test chamber 110. The vibrating conveyor transports the loading box 210 from back to front and drives the loading box 210 to vibrate, enabling the gripping robot 300 to grasp the sample inside the loading box 210 at the front end of the vibrating conveyor. In this embodiment of the invention, the vibrating conveyor is a common device that uses the directional force generated by vibration to transport materials. It can simultaneously perform conveying and vibration operations. Its main components include a vibrator, a conveying trough, a spring assembly, and a support frame. The vibrator, as a power source, generates periodic vibration force through the rotation of an internal eccentric block, directly driving the conveying trough to vibrate. One end of the spring assembly is connected to the conveying trough, and the other end is fixed to the frame 100. The spring assembly supports the conveying trough and also buffers vibration impact through its own elastic deformation, ensuring stable vibration transmission. The loading box 210 is set in the conveying trough of the vibrating conveyor. The conveying trough vibrates regularly under the action of vibration force and spring assembly, and drives the loading box 210 to be smoothly conveyed from back to front. This makes the inner wall of the vibrating loading box 210 continuously collide with the sample. When the loading box 210 reaches the front end, it can be accurately grasped by the gripping robot 300.

[0036] In this embodiment of the invention, the hot air generating device includes a hot air generating mechanism and a first suction mechanism. The air outlet of the hot air generating mechanism and the suction end of the first suction mechanism are respectively disposed on two opposite inner sidewalls of the first test chamber 110. The hot air generating mechanism is used to blow hot air into the first test chamber 110, and the first suction mechanism is used to draw gas from the first test chamber 110, so that hot air flows within the first test chamber 110. It is understood that the air outlet of the hot air generating mechanism and the suction end of the first suction mechanism are respectively disposed on the opposite front and rear inner sidewalls of the first test chamber 110. With the cooperation of the hot air generating mechanism and the first suction mechanism, directional hot air flow can be formed within the first test chamber 110, making the sample within the first test chamber 110 more evenly heated, the simulation effect closer to reality, and thus improving the reliability of the pretreatment. In this embodiment of the invention, the hot air generating mechanism includes a resistance wire heater, a fan, and an air outlet duct. The air inlet of the air outlet duct is connected to the output end of the fan, and the air outlet of the air outlet duct is located on the inner wall of the first test chamber 110. The resistance wire heater is used to heat the air, and the fan blows the hot air into the first test chamber 110 through the air outlet duct. The first suction mechanism includes a first suction pump, a first suction duct, and a first filter. The air inlet of the first suction duct is located on the inner wall of the first test chamber 110, and the air outlet of the first suction duct is connected to the first suction pump. The first filter is installed at the air inlet of the first suction duct. The first suction pump draws gas from the first test chamber 110 through the first suction duct, thereby cooperating with the hot air generating mechanism to form a hot air circulation. Both the hot air generating mechanism and the first suction mechanism are common mechanisms in the field of airflow dynamics, and will not be described further here.

[0037] In this embodiment of the invention, the steam generating device includes a steam generating mechanism and a second suction mechanism. The outlet of the steam generating mechanism and the suction end of the second suction mechanism are respectively located on two opposing inner sidewalls of the second test chamber 120. The steam generating mechanism is used to deliver steam into the second test chamber 120, and the second suction mechanism is used to suction the gas in the second test chamber 120, so that steam flows within the second test chamber 120. It is understood that the outlet of the steam generating mechanism and the suction end of the second suction mechanism are respectively located on the opposing front and rear inner sidewalls of the second test chamber 120. With the cooperation of the steam generating mechanism and the second suction mechanism, directional steam flow can be formed within the second test chamber 120, which can efficiently simulate the usage scenario of the sample in a steam environment, ensuring that the sample is in uniform and sufficient contact with the steam, and improving the consistency and reliability of the steam treatment effect. The steam generating mechanism consists of a steam generator, a steam booster pump, and a steam pipeline. The outlet of the steam pipeline is located on the inner wall of the second test chamber 120, and the inlet of the steam pipeline is connected to the steam generator. The steam generator produces steam by heating water, and the steam booster pump pressurizes the steam and sends it into the second test chamber 120 through the steam pipeline. The second suction mechanism includes a second suction pump, a second suction pipeline, and a second filter. The inlet of the second suction pipeline is located on the inner wall of the second test chamber 120, and the outlet of the second suction pipeline is connected to the second suction pump. The second filter is installed at the inlet of the second suction pipeline. The second suction pump draws gas from the second test chamber 120 through the second suction pipeline, thus cooperating with the steam generating mechanism to form a steam cycle. Both the steam generating mechanism and the second suction mechanism are common in the field of pneumatic power, and will not be described further here.

[0038] In this embodiment of the invention, the multi-environment simulation pretreatment testing machine for food contact materials further includes a heating device 400, which is disposed within the third test chamber 130. The heating device 400 is used to heat the solvent within the third test chamber 130. It is understood that the heating device 400 can heat the solvent within the third test chamber 130 to simulate the usage scenario of samples contacting high-temperature solvents, and to examine the effect of temperature on the leaching of microplastics and nanoplastics. The heating device 400 further enriches the environmental simulation conditions to better reflect the combined effects of multiple factors in actual use, improving the comprehensiveness and accuracy of the pretreatment, thereby facilitating a more precise assessment of the safety of food contact materials. In this embodiment of the invention, the heating temperature and heating time of the heating device 400 are precisely adjustable. The heating device 400 is a common resistance wire heating device 400, which will not be further described here.

[0039] refer to Figure 1The gripping robot 300 includes a clamping and rotating mechanism and a multi-axis drive mechanism. The multi-axis drive mechanism is mounted on the frame 100, and its output end is connected to the clamping and rotating mechanism. The multi-axis drive mechanism drives the clamping and rotating mechanism to move in the forward and backward and up and down directions. The clamping and rotating mechanism clamps the sample and drives it to rotate. It can be understood that the multi-axis drive mechanism can drive the clamping and rotating mechanism to move in the forward and backward and up and down directions. First, the multi-axis drive mechanism moves the clamping and rotating mechanism to the loading box 210, enabling the clamping and rotating mechanism to clamp the sample inside the loading box 210. After the clamping and rotating mechanism holds the sample, the multi-axis drive mechanism then drives the clamping and rotating mechanism and the sample held by it to move sequentially into the first test chamber 110, the second test chamber 120, and the third test chamber 130. After the sample has remained in the first test chamber 110, the second test chamber 120, and the third test chamber 130 for a predetermined time, the multi-axis drive mechanism drives the clamping and rotating mechanism and the sample held by it to move to the next step. During the time the sample remains in the first test chamber 110, the second test chamber 120, and the third test chamber 130, the clamping and rotating mechanism can drive the sample to rotate, ensuring that all parts of the sample can be evenly contacted by hot air, steam, and solvent, improving the comprehensiveness and accuracy of the simulation, and thus ensuring the pretreatment effect.

[0040] refer to Figure 1 The multi-environment simulation pretreatment test machine for food contact materials also includes a housing 500, which is mounted on the frame 100. The vibrating conveyor, hot air generator, steam generator, gripping robot 300, first test chamber 110, second test chamber 120, and third test chamber 130 are all housed within the housing 500. It is understood that by enclosing the vibrating conveyor, hot air generator, steam generator, gripping robot 300, first test chamber 110, second test chamber 120, and third test chamber 130 within the housing 500, interference from the external environment on the internal test conditions can be reduced, ensuring the stability of temperature, steam, and other environmental simulations. (Reference) Figure 1 The housing 500 is equipped with an observation window 530. Understandably, the observation window 530 allows the experimenter to directly observe the operating status of components such as the vibrating conveyor, various test chambers, and gripping robot 300 inside the housing 500, as well as the condition of the samples during the multi-environment simulation process, without opening the housing 500. This facilitates timely monitoring of the test progress and allows for rapid troubleshooting when abnormalities are detected, thus improving the ease of use of the multi-environment simulation pretreatment test machine for food contact materials.

[0041] refer to Figure 1The housing 500 is provided with loading and unloading ports 540, which are correspondingly positioned at the rear end of the vibrating conveyor. The loading and unloading ports 540 are used for the material container 210 to pass through. Understandably, when pretreatment for multi-environment simulation of the sample is required, the experimenter can place the sample into the material container 210 and place it through the loading and unloading ports 540 on the housing 500 onto the rear end of the vibrating conveyor. The vibrating conveyor then drives the material container 210 from back to front, causing it to vibrate. When the material container 210 moves to the front end of the vibrating conveyor, the conveyor stops, allowing the gripping robot 300 to grasp the sample inside the material container 210. After completing the multi-environment simulation of the sample, the gripping robot 300 places the sample back into the material container 210 at the rear end of the vibrating conveyor, and then the vibrating conveyor transports the material container 210 from front to back. When the loading box 210 moves to the rear end of the vibrating conveyor, the vibrating conveyor stops conveying, and the experimenter can then remove the loading box 210 from the rear end of the vibrating conveyor through the loading / unloading port 540, allowing the experimenter to remove the sample from the loading box 210 that has undergone multi-environment simulation. In this embodiment of the invention, a cover door is hinged to the housing 500. The cover door can open the loading / unloading port 540 to allow the experimenter to load and unload samples, and the cover door can close the loading / unloading port 540 to reduce the interference of the external environment on the internal test conditions.

[0042] refer to Figure 1 The multi-environment simulation pretreatment test chamber for food contact materials also includes multiple xenon arc lamps 510 and multiple ultraviolet lamps 520. The xenon arc lamps 510 are all located inside a housing 500 and on the top wall of the housing 500. Similarly, the ultraviolet lamps 520 are also located inside the housing 500 and on the top wall of the housing 500. Understandably, the multiple xenon arc lamps on the top wall inside the housing 500 provide sufficient illumination to simulate the effects of natural light on food contact materials; that is, the xenon arc lamps 510 are used to simulate natural light aging. The multiple ultraviolet lamps 520 can simulate ultraviolet irradiation environments to examine the effect of ultraviolet light on the dissolution of microplastics and nanoplastics in the materials; that is, the ultraviolet lamps 520 are used to simulate ultraviolet light aging. The xenon arc lamp and ultraviolet lamp 520 add a dimension to environmental simulation, enabling the food contact material multi-environment simulation pretreatment test machine to integrate various environmental conditions such as temperature, steam, mechanical force, solvent, and light aging, in order to more comprehensively simulate actual use scenarios, thereby improving the integrity of pretreatment and the accuracy of evaluation.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
