[0050] The present invention will be further described below with reference to the accompanying drawings.

[0051] In recent years, to ensure the safety, stability, and reliability of rail transportation, investment in railway construction has increased. Construction projects such as double-tracking, station renovations, and electrification have increased annually. Since railway construction projects are often conducted outdoors, canteens are set up along the construction lines to support logistics. To enrich the dining experience, canteens prepare pickled vegetables and sauerkraut. The production of pickled vegetables and pickles produces nitrites. Long-term, high-volume consumption of these products can be harmful to the human body and increase the risk of illness. Therefore, to ensure the food safety of railway workers, railway canteens are required to test their processed pickled vegetables for nitrite.

[0052] The existing detection methods are: first, staff members take samples, mark them, and then bring them back to the testing room for testing; but the operation process of bringing samples back to the testing room may contaminate the samples, which will hinder subsequent processing; second, staff members carry detection containers, colorimetric cards, purified water and detection reagents, mix the samples, purified water and detection reagents inside the detection containers on site, and detect them by comparing colors using colorimetric cards; however, when conducting random inspections on site, since there are many samples to be inspected and the detection containers cannot be mixed if they are not clean, staff members need to carry more containers, which brings inconvenience to the work, and the samples and solutions used in the inspection are not easy to handle.

[0053] Example 1

[0054] like Figure 1 、 Figure 2As shown, in order to solve the above technical problems, an embodiment of the present invention provides a food testing device, including a support platform 10, a traction assembly 20, a detection bag assembly 30 and an opening assembly 40; the traction assembly 20 includes a traction drive part 210 and a traction main shaft 220 arranged at intervals in the length direction of the support platform 10, and the traction main shaft 220 is rotatably set on the support platform 10; the detection bag assembly 30 includes a plurality of detection bags 310 connected in sequence, one end of the detection bag assembly 30 is set on the traction main shaft 220 and the other end is set on the traction drive part 210, the detection bag assembly 30 is wound around the traction main shaft 220 and moves under the action of the traction assembly 20; the opening assembly 40 is set on the support platform 10 and is located between the traction drive part 210 and the traction main shaft 220; the opening assembly 40 is constructed to be able to open the detection bag 310 moved to the opening assembly 40 to add the sample to be tested into the detection bag 310.

[0055] As can be seen from the above, by providing the test bag assembly 30 as a test container to hold the samples to be tested, different samples to be tested are placed in different test bags 310 for testing. This eliminates the need for workers to carry test containers or clean them. Workers can simply switch to a new test bag 310 after each test. This not only improves work efficiency but also avoids contamination caused by mixing and using unclean test containers. Sample testing can also be completed on-site without the need to bring the samples back to the testing room for testing, further avoiding sample contamination. The traction drive unit 210 drives the test assembly to move, causing the test bag 310 wrapped around the traction spindle 220 to leave the traction spindle 220 and move the test bag 310 to the opening assembly 40. The opening assembly 40 automatically opens the test bag 310, eliminating the need for workers to manually open the test bag 310, further improving work efficiency. After the test is completed, the test bag 310 is wrapped around the traction drive unit 210.

In addition, the first support plate 130, the second support plate 140 and the vertical plate 120 may be connected in a manner including, but not limited to, a detachable connection.

[0057] It should also be noted that the test bag 310 is a plastic test bag 310, which includes a main body 3101 and an extension portion 3102. The opening component 40 is inserted into the extension portion 3102, and the bottom of the extension portion 3102 is connected to the top of the main body 3101, and the extension portion 3102 is connected to the main body 3101. The two adjacent test bags 310 are connected through the extension portion 3102, and the extension portions 3102 between the two adjacent test bags 310 are connected to avoid structural interference between the test bag assembly 30 and the opening component 40 during movement, and a channel is reserved for the opening component 40; the bottom of the main body 3101 is closed and the top is open, but due to the adhesion between the plastic film bag surfaces of the main body 3101, the opening of the main body 3101 is at least partially adhered together, and the plastic film bag surfaces of the main body 3101 need to be separated by the opening component 40, thereby opening the opening and preparing for the addition of the sample to be tested. In addition, the detection bag 310 can be a transparent plastic bag to facilitate observation of the color of the solution during the detection process.

[0058] It should also be noted that the samples to be tested are pickled foods, for example, the samples to be tested are pickled kimchi and sauerkraut.

[0059] It should also be noted that if Figure 1 As shown, the length direction is parallel to the X direction, and the width direction is parallel to the Y direction.

[0062] As can be seen from the above, by providing the test bag assembly 30 as a test container to hold the samples to be tested, different samples to be tested are placed in different test bags 310 for testing. This eliminates the need for workers to carry test containers or clean them. Workers can simply switch to a new test bag 310 after each test. This not only improves work efficiency but also avoids contamination caused by mixing and using unclean test containers. Sample testing can also be completed on-site without the need to bring the samples back to the testing room for testing, further avoiding sample contamination. The traction drive unit 210 drives the test assembly to move, causing the test bag 310 wrapped around the traction spindle 220 to leave the traction spindle 220 and move the test bag 310 to the opening assembly 40. The opening assembly 40 automatically opens the test bag 310, eliminating the need for workers to manually open the test bag 310, further improving work efficiency. After the test is completed, the test bag 310 is wrapped around the traction drive unit 210.

[0063] It should be noted that the support platform 10 includes a base plate 110, a vertical plate 120, a first support plate 130, and a second support plate 140. The vertical plate 120 is disposed on the base plate 110, and the first support plate 130 and the second support plate 140 are disposed on the vertical plate 120, with the first support plate 130 and the second support plate 140 being spaced apart in the height direction. In addition, the first support plate 130, the second support plate 140 and the vertical plate 120 may be connected in a manner including, but not limited to, a detachable connection.

[0064] It should also be noted that the test bag 310 is a plastic test bag 310, which includes a main body 3101 and an extension portion 3102. The opening component 40 is inserted into the extension portion 3102, and the bottom of the extension portion 3102 is connected to the top of the main body 3101, and the extension portion 3102 is connected to the main body 3101. The two adjacent test bags 310 are connected through the extension portion 3102, and the extension portions 3102 between the two adjacent test bags 310 are connected to avoid structural interference between the test bag assembly 30 and the opening component 40 during movement, and a channel is reserved for the opening component 40; the bottom of the main body 3101 is closed and the top is open, but due to the adhesion between the plastic film bag surfaces of the main body 3101, the opening of the main body 3101 is at least partially adhered together, and the plastic film bag surfaces of the main body 3101 need to be separated by the opening component 40, thereby opening the opening and preparing for the addition of the sample to be tested. In addition, the detection bag 310 can be a transparent plastic bag to facilitate observation of the color of the solution during the detection process.

[0065] It should also be noted that the samples to be tested are pickled foods, for example, the samples to be tested are pickled kimchi and sauerkraut.

[0066] It should also be noted that if Figure 1As shown, the length direction is parallel to the X direction, and the width direction is parallel to the Y direction.

[0067] like Figure 1 As shown, in some embodiments, the detection bag assembly 30 includes a colorimetric card 320 respectively disposed on each detection bag 310 .

[0068] By setting the colorimetric card 320 on the test bag 310, it is convenient for the staff to directly compare the color of the solution in the test bag 310 with the color of the colorimetric card 320 during the test process, thereby determining the nitrite content of the solution and realizing the detection of the nitrite content of the sample to be tested.

[0069] It should be noted that the color of the color chart 320 gradually becomes darker from left to right.

[0070] like Figure 1 As shown, in some embodiments, the traction drive unit 210 includes a traction motor 2101 and a drive spindle 2102; the traction motor 2101 is arranged on the support platform 10; the drive spindle 2102 is arranged on the rotating shaft of the traction motor 2101; wherein, one end of the detection bag assembly 30 is arranged on the drive spindle 2102.

[0071] The traction motor 2101 drives the driving main shaft 2102 to rotate, thereby rolling up one end of the detection bag assembly 30, so that the detection bag assembly 30 passes through the opening assembly 40, and the automatic switching of the detection bag 310 is achieved.

[0072] It should be noted that the traction motor 2101 is arranged on the first support plate 130, and the driving shaft 2102 is located between the first support plate 130 and the second support plate 140; the two ends of the traction shaft 220 are rotatably arranged on the first support plate 130 and the second support plate 140 through rolling bearings.

[0073] like Figure 2 As shown, in some embodiments, the opening component 40 also includes an opening support plate 410, an opening support shaft 420, two bending components 430 and an opening drive 440; the opening support plate 410 is arranged on the support platform 10 and is arranged at intervals along the length direction; the two ends of the opening support shaft 420 are respectively arranged on the opening support plate 410; the two bending components 430 are rotatably arranged on the opening support shaft 420, and the two bending components 430 are arranged at intervals along the opening support shaft 420; the opening drive 440 is arranged on the support platform 10, the opening drive 440 is connected to the two bending components 430, and the opening drive 440 is constructed to drive the two bending components 430 to rotate in opposite directions to open the detection bag 310.

[0074] By setting up a bending component 430 and inserting the bending component 430 into the detection bag 310, the opening driving member 440 drives the two bending components 430 to rotate in opposite directions, so that the distance between the two bending components 430 increases, thereby separating the plastic film bag surface that is adhered to the detection bag 310, and opening the main body 3101; the whole process is simple and convenient.

[0075] It should be noted that the opening support plate 410 is arranged at the bottom of the first support plate 130, and the two bending components 430 have the same structure. One of the bending components 430 is symmetrical front to back about the opening support axis 420 and can overlap with the other bending component 430 after being translated along the length direction.

[0076] like Figure 2 As shown, in some embodiments, the bending assembly 430 includes a bending plate 4301 and a bending plate 4301, the upper part of the bending plate 4301 is rotatably set on the opening support shaft 420, the lower part of the bending plate 4301 is provided with a bending angle, and the lower end of the bending plate 4301 is inserted into the detection bag assembly 30; the connecting plate 4302 is obliquely arranged at the upper end of the bending plate 4301; wherein the telescopic rod of the opening driving member 440 is movably connected to the end of the connecting plate 4302 away from the bending plate.

[0077] By rotatably arranging the bending plate 4301 on the opening support shaft 420, the bending plate 4301 rotates around the opening support shaft 420 as the axis, and the telescopic rod of the opening driving member 440 is extended and retracted to provide power for the rotation of the bending plate 4301. The telescopic rod of the opening driving member 440 drives the connecting plate 4302 to move, and the bending plate 4301 rotates accordingly. The rotation directions of the two bending plates 4301 are opposite, thereby opening the detection bag 310.

[0078] It should be noted that the bending angle is greater than 90° and less than 180°; the bending plate 4301 includes a first bending section and a second bending section, the first bending section has a first bending surface and a second bending surface that are relatively arranged, the second bending section is arranged on the first bending surface, the bending angle is located between the first bending section and the second bending section, and the connecting plate 4302 is arranged on the second bending surface; in addition, the lower end of the second bending section is always located in the extension portion 3102 to facilitate the opening of the detection bag 310.

[0079] It should also be noted that the opening drive member 440 includes but is not limited to an electric push rod; Figure 3As shown, the opening assembly 40 also includes a drive block 4401, which is connected to the telescopic rod of the electric push rod. The bottom of the drive block 4401 is provided with two slots spaced apart in the length direction and extending in the width direction. A slider is provided in each slot, which is slidably connected to the slot. The end of the connecting plate 4302, away from the bending plate, is hinged to the bottom of the slider. The telescopic rod of the electric push rod moves the drive block 4401 in the height direction, and the slider moves along the slot. The two sliders move in opposite directions, driving the connecting plate 4302 to rotate, and the bending plate 4301 rotates accordingly. The two bending plates 4301 rotate in opposite directions, thereby changing the distance between the two bending plates 4301 and opening the inspection bag 310.

[0080] like Figure 1 As shown, in some embodiments, the traction assembly 20 also includes a pressure wheel portion 230 located on both sides of the opening assembly 40, and the pressure wheel portion 230 includes two pressure wheels 2301 rotatably arranged on the support platform 10, and the two pressure wheels 2301 are arranged at intervals along the width direction of the support platform 10; wherein, the detection bag 310 is passed through the two pressure wheels 2301.

[0081] The pressure wheel 230 is provided to pull the detection bag assembly 30 , so that the detection bag 310 can move smoothly under the action of the traction drive unit 210 and prevent the detection bag 310 from falling too much downward under the action of gravity of the sample to be detected.

[0082] It should be noted that the pressing wheel 2301 is rotatably disposed on the first support plate 130 .

[0083] like Figure 1 As shown, in some embodiments, the food testing device also includes an injection pump 50 and an injection tube 60; the injection pump 50 is arranged on the support platform 10, and the inlet of the injection pump 50 is connected to the water tank; the injection tube 60 is connected to the outlet of the injection pump 50 to inject water into the detection bag 310.

[0084] An injection pump 50 is provided to extract a fixed amount of water from the water tank and inject the water into the detection bag 310 through the injection pipe 60, so that the nitrite contained in the sample to be detected is dissolved, thereby facilitating the detection.

[0085] It should be noted that the injection pump 50 is arranged on the first support plate 130, and pure water is set in the water tank; the injection pump 50 includes but is not limited to a micro-dosing pump, and its specific structure and working principle are all existing technologies, which will not be repeated in this application.

[0086] like Figure 1As shown, in some embodiments, the food testing device further includes a waste collection assembly 70 disposed on the support platform 10 , the waste collection assembly 70 being located below the opening assembly 40 , and the waste collection assembly 70 being configured to be able to classify and collect the samples to be tested in the testing bag 310 .

[0087] By providing the waste collection assembly 70 , the samples and solutions to be tested in the testing bag 310 are classified and collected for processing, thereby avoiding environmental pollution and solving the problem of convenient processing of the samples and solutions to be tested after testing.

[0088] like Figure 1 As shown, in some embodiments, the waste collection assembly 70 includes a water trough 710 and a collecting knife 720; the water trough 710 is arranged on the support platform 10, the water trough 710 is located below the opening assembly 40, and a water outlet is provided at the bottom of the water trough 710; the collecting knife 720 is arranged in the water trough 710 and is located on the side of the water trough 710 close to the traction drive unit 210; wherein, on a plane perpendicular to the height direction, the projection of the collecting knife 720 overlaps with the projection of the water outlet.

[0089] When the traction assembly 20 drives the detection bag assembly 30 to move and one of the detection bags 310 moves to the opening assembly 40, the detection bag 310 is located in the water receiving trough 710; when the detection is completed, the traction assembly 20 drives the detection bag assembly 30 to move in the direction of the traction drive part 210, and the detection bag 310 in the water receiving trough 710 and the collecting knife 720 move relative to each other, and the collecting knife 720 pierces the detection bag 310, and the samples and solutions to be tested in the detection bag 310 flow into the water receiving trough 710. At the same time, the projection of the collecting knife 720 overlaps with the projection of the water outlet, limiting the position between the collecting knife 720 and the water outlet, so that after the detection bag 310 is pierced by the collecting knife 720, the samples and solutions to be tested in the detection bag 310 can be quickly discharged through the water outlet.

[0090] It should be noted that the shape of the collecting blade 720 can be triangular; in addition, the water receiving trough 710 is provided on the second support plate 140 .

[0091] It should also be noted that the waste collection assembly 70 also includes a funnel 760 arranged at the water outlet, which plays the role of converging and diverting water.

[0092] like Figure 1 As shown, in some embodiments, the waste collection assembly 70 also includes a limiting ring 730, a collecting cylinder 740 and a filter cylinder 750; the limiting ring 730 is arranged on the support platform 10 and is located below the water outlet; the collecting cylinder 740 is arranged in the limiting ring 730; and the filter cylinder 750 is arranged in the collecting cylinder 740.

[0093] After the sample and solution flowing out of the water outlet are filtered by the filter cartridge 750, the sample is isolated in the filter cartridge 750, and the solution flows into the collection cartridge 740, thereby achieving the classification and collection of the sample and solution. In addition, the collection cartridge 740 is limited by the limit ring 730 to prevent the collection cartridge 740 from shifting.

[0094] It should be noted that the limiting ring 730 is arranged on the bottom plate 110, and the limiting ring 730 matches the shape of the collecting cylinder 740; a plurality of filter holes are provided on the filter cylinder 750, and there is a distance between the bottom of the filter cylinder 750 and the bottom of the collecting cylinder 740.

[0095] The working process of the food detection device provided by the utility model is specifically as follows:

[0096] The traction motor 2101 is started, driving the main shaft 2102 to rotate and reel the detection bag assembly 30, and the detection bag 310 on the traction main shaft 220 leaves the traction main shaft 220; when one of the detection bags 310 moves below the opening assembly 40 and is located in the water receiving tank 710, the opening drive member 440 is started, and the opening drive member 440 drives the connecting plate 4302 to move. The connecting plate 4302 drives the bending plate 4301 to rotate about the opening support shaft 420, and the two bending plates 4301 rotate in opposite directions, and the distance between the two bending plates 4301 increases, thereby opening the detection bag 310;

[0097] The staff puts the sample to be tested into the test bag 310, starts the injection pump 50 to inject water into the test bag 310, and then adds the nitrite detection reagent into the test bag 310. After standing for ten minutes, the staff observes the color of the solution in the test bag 310 and compares it with the color card 320 on the test bag 310. The color card 320 with a color close to the solution corresponds to the nitrite content in the solution, thereby obtaining the nitrite content of the sample to be tested;

[0098] After the test is completed, the traction motor 2101 is started to drive the main shaft 2102 to rotate and reel the test bag assembly 30. Relative movement occurs between the test bag 310 in the water receiving trough 710 and the collecting knife 720. The collecting knife 720 pierces the test bag 310, and the solution in the test bag 310 and the sample to be tested flow into the water outlet of the water receiving trough 710, and flow into the collecting tube 740 under the guidance of the funnel 760. The sample to be tested is isolated in the filter tube 750, and the solution flows into the collecting tube 740.

[0099] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
