Description

Technical Field

[0001] This invention relates to the field of food testing technology, and in particular to an online automatic sampling machine for food testing with a sealing function. Background Technology

[0002] With the rapid development of the food industry and the increasing emphasis on food safety, quality monitoring during food production has become crucial. Online sampling and testing is a vital step in ensuring that each batch of products meets safety standards. Compared to traditional manual sampling methods, online automated sampling machines can perform standardized operations according to preset times or frequencies, which not only improves sampling efficiency but also effectively avoids random errors and cross-contamination risks associated with manual operation.

[0003] Current technologies for online detection of solid or particulate materials on food conveyor belts typically involve manually or using simple mechanical devices to extract samples, temporarily collecting them in open containers, and then manually transferring them to a separate packaging station for sealing. This approach has two significant drawbacks. First, the sampling and packaging actions are severely separated in both physical space and time, causing the samples to be exposed to the workshop environment for extended periods during the transfer process. This makes them highly susceptible to secondary contamination by microorganisms or dust, severely affecting the accuracy of the test results. Second, existing equipment generally lacks the design capability to highly integrate automatic sampling with automatic film supply and heat sealing functions, resulting in large equipment footprints, low automation levels, and difficulty in achieving truly unmanned, closed-loop operation on the side of a compact production line.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to achieve a physical closed loop between the sampling path and the packaging station by directly fixing the filling tube to the bottom surface of the rotating block and cooperating with the internally rotating collection tube for direct gravity unloading in the reset state. This principle utilizes a cylinder-driven electric heating plate to instantly fused and seal below the filling tube outlet, completely sealing the material exposure path through a tight mechanical connection. This achieves in-situ anti-contamination during sampling and packaging, thus overcoming the shortcomings of existing technologies where prolonged exposure to the workshop environment during transfer easily leads to secondary contamination by microorganisms or dust, severely affecting the accuracy of test results.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an online automatic sampling machine for food testing with sealing function, comprising a transport frame and a rotating block, wherein the rotating block is fixedly installed on one side surface of the transport frame, a rotating groove is provided on one side surface of the rotating block, a deflection rod is rotatably installed on the inner wall of the rotating block, a connecting block is fixedly installed on the outer surface of the deflection rod, a positioning tube is fixedly installed on one side surface of the connecting block, a collection tube is rotatably installed on the inner wall of the positioning tube, a collection port is opened on the outer surface of the collection tube, a rotary motor is fixedly installed on one side surface of the positioning tube, and a limit block is fixedly installed on the outer surface of the positioning tube;

[0011] Furthermore, there are several universal rods, which are arranged in a circular array and equidistantly distributed on the inner wall of the setting block. The universal rods are connected end to end to form a closed loop. Each universal rod has a rubber wheel distributed on its outer surface. The stepper motor is connected to the universal rod through the track shaft and drive track. The rubber wheel is in contact with the outer surface of the filling tube.

[0012] Furthermore, there are two cylinders, which are equidistantly distributed on the bottom surface of the mounting block. Each cylinder has an electric heating plate corresponding to its extended end, and the two electric heating plates are in contact with each other.

[0013] Furthermore, the transport assembly includes a rotating shaft rotatably mounted on one side surface of the inner wall of the transport frame, a drive shaft rotatably mounted on one side surface of the inner wall of the transport frame, a drive wheel provided on the outer surface of the drive shaft, a transport track rotatably connected to the outer surface of the rotating shaft, and a drive motor fixedly mounted on one side surface of the transport frame.

[0014] Furthermore, there are several rotating shafts, which are arranged in a linear array and equidistantly distributed on the inner wall of the transport frame.

Therefore, they should not be construed as limitations on this invention.

[0030] like Figures 1-10As shown, an online automatic sampling machine for food testing with sealing function includes a transport frame 1 and a rotating block 101 fixedly installed on one side surface of the transport frame 1;

[0031] A rotating groove 102 is provided on one side surface of the rotating block 101, and a deflection rod 103 is rotatably installed on its inner wall. A connecting block 104 is fixedly installed on the outer surface of the deflection rod 103. The rotation of the deflection rod 103 can drive the positioning tube 105 to rotate and flip through the connecting block 104.

[0032] The positioning tube 105 is fixedly installed on one side surface of the connecting block 104, and a collection tube 106 with a collection port 107 on the outer surface is rotatably installed on its inner wall. Two limiting blocks 109 for limiting are evenly distributed on the outer surface of the positioning tube 105.

[0033] A rotary motor 108 is fixedly installed on one side surface of the positioning tube 105. The output end of the rotary motor 108 is fixedly connected to one end of the collection tube 106 to drive the collection tube 106 to rotate inside the positioning tube 105 to achieve sample shoveling and sealing.

[0034] In this embodiment of the invention, the rotary motor 108 installed on the side of the positioning tube 105 is started, and its output end drives the collection tube 106, which is rotated inside the positioning tube 105, to rotate, so that the collection port 107 on the outer surface of the collection tube 106 is like a spoon scooped into the material flow to collect the sample. Then the rotary motor 108 rotates in the opposite direction to drive the collection tube 106 to reset and close the collection port 107 to lock the sample.

[0035] Reference Figures 1-10 Specifically, the rotating component includes two limiting grooves 2 symmetrically opened on both sides of the inner wall of the rotating groove 102, and the inner walls of the two limiting grooves 2 respectively slide in contact with the outer surface of the corresponding limiting block 109.

[0036] Electric telescopic rods 201 are rotatably mounted on both sides of the inner wall of the rotating block 101. A deflection block 206 is rotatably mounted at the end of each electric telescopic rod 201, and the two deflection blocks 206 are fixedly connected to the two ends of the deflection rod 103 respectively. The extension and retraction of the electric telescopic rod 201 can drive the deflection block 206 and the deflection rod 103 to perform deflection actions.

[0037] A leak-proof plate 202 is fixedly installed on one side surface of the rotating block 101, and a filling pipe 203 is fixedly installed on the bottom surface of the rotating block 101.

[0038] The inner wall of the rotating groove 102 is provided with a threaded groove 204. The inner wall of the threaded groove 204 is threadedly connected to a limit ring 205. By adjusting the position of the limit ring 205 in the threaded groove 204, the downward movement of the packaging film on the outside of the filling tube 203 can be controlled by damping.

[0039] In this embodiment of the invention, when it is necessary to sample the food on the production line, the electric telescopic rods 201 installed on both sides of the inner wall of the rotating block 101 are simultaneously activated and retracted. The extended end of the electric telescopic rod 201 pulls the deflection block 206, which is rotatably connected to its end, downward. The movement of the deflection block 206 forces the deflection rod 103, which passes laterally through the rotating block 101, to rotate around its own axis. As the deflection rod 103 rotates, the connecting block 104 fixedly installed on it drives the positioning tube 105 and the limiting block 109 installed on the outside of the positioning tube 105 and inserted into the limiting groove 2 on one side of the inner wall of the rotating groove 102 to move together. This causes the positioning tube 105, under the physical guidance and constraint of the trajectory of the limiting groove 2, to gradually deflect 90 degrees downward from the initial high vertical waiting state to the horizontal state, and finally to approach the food flow on the surface of the transport conveyor belt 403.

[0040] Reference Figures 1-10 Specifically, the sealing assembly includes a setting block 3, whose inner wall is equidistantly mounted with several universal rods 301 that are connected end to end to form a closed loop;

[0041] Each universal rod 301 has a rubber wheel 302 fixedly installed on its outer surface, and the rubber wheel 302 is in active contact with the outer surface of the filling tube 203 to drive the packaging film to move downward through friction.

[0042] A stepper motor 304 is mounted on the outer surface of the set block 3. A track shaft 305 is mounted on the output end of the stepper motor 304. The stepper motor 304 forms a transmission connection with the universal rod 301 through the track shaft 305 and the drive track 303 that is connected to the outer surface of the universal rod 301, so as to drive the entire universal rod closed-loop array to rotate.

[0043] Two cylinders 306 are equidistantly installed on the bottom surface of the block 3. Each cylinder 306 has an electric heating plate 307 installed at its extended end. The two electric heating plates 307 are in contact with each other. The cylinders 306 drive the two sets of electric heating plates 307 to move closer to each other to achieve the sealing of the sample.

[0044] In this embodiment of the invention, the automatic film feeding and packaging action is performed immediately afterward. The stepper motor 304 installed on the outside of the setting block 3 is started, and the track shaft 305 installed at the output end and the drive track 303 drive the entire ring array of universal rods 301 on the inner wall of the setting block 3 to rotate. This array is composed of several universal rods 301 that are connected end to end by ball shafts to form a closed loop and surround the filling tube 203. The inner side of the rubber wheel 302 on each universal rod 301 is pressed tightly against the surface of the packaging film at the bottom of the filling tube 203. As the entire closed loop of universal rods 301 revolves around the filling tube 203, the rubber wheel 302 grips the outer surface of the packaging film by friction, overcoming the damping force applied by the limiting ring 205 installed in the threaded groove 204 on the bottom inner wall of the rotating block 101, and accurately pulls the outermost packaging film down along the filling tube 203 by a predetermined bag length distance, forming a new packaging space for the next sampling.

[0045] The transport assembly includes a rotating shaft 4, which is rotatably mounted on one side of the inner wall of the transport frame 1. A drive shaft 401 is rotatably mounted on one side of the inner wall of the transport frame 1. A drive wheel 402 is provided on the outer side of the drive shaft 401. A transport track 403 is rotatably connected to the outer side of the rotating shaft 4. A drive motor 404 is fixedly mounted on one side of the transport frame 1.

[0046] There are several rotating shafts 4, which are arranged in a linear array and are equidistantly distributed on the inner wall of the transport frame 1. There are several driving wheels 402, which are arranged in a linear array and are equidistantly distributed on the outer surface of the driving shaft 401. The outer surface of the driving wheel 402 is in rotational contact with the inner wall of the transport track 403. The output end of the drive motor 404 is fixedly connected to one end of the driving shaft 401.

[0047] Specific usage process: Before the online automatic sampling machine for food testing with sealing function of the present invention is put into operation, the operator first needs to complete the film loading work, that is, to put the pre-made long cylindrical plastic packaging film on the outer surface of the filling tube 203, and fold and wrinkle it during the loading, and put it on the outer surface of the vertically downward filling tube 203 fixedly installed on the bottom surface of the rotating block 101, forming a tight film stack. Then, the operator needs to rotate the limiting ring 205 into the threaded groove 204 opened in the inner wall of the rotating groove 102, and adjust the limiting ring 205 downward until it presses down on the film stack on the filling tube 203, so that it applies appropriate pressure to the top of the film stack. In this way, the damping force generated by the limiting ring 205 pressing the film stack is used to ensure that when the rubber wheel 302 pulls the film, only the outermost film is pulled down, thus effectively preventing the entire stack of films from slipping down at the same time due to excessive gravity or tension.

[0048] After the preparation work is completed, the machine is started. The drive motor 404 installed on one side of the inner wall of the transport frame 1 starts to work. When the drive motor 404 starts, it drives the drive shaft 401 installed at the output end to rotate. The rotation of the drive shaft 401 drives several drive wheels 402, which are fixedly connected to its outer surface and are arranged in a linear array, to rotate synchronously. The outer surface of the drive wheel 402 rotates and contacts the inner wall of the transport track 403. Through friction, the transport track 403 and the auxiliary rotating shaft 4 are driven to run smoothly, thereby carrying the food material to be tested forward continuously.

[0049] When food samples need to be taken from the production line, the electric telescopic rods 201 installed on both sides of the inner wall of the rotating block 101 retract synchronously. The extended end of the electric telescopic rod 201 pulls the deflection block 206, which is rotatably connected to its end, downward. The movement of the deflection block 206 forces the deflection rod 103, which passes laterally through the rotating block 101, to rotate around its own axis. As the deflection rod 103 rotates, the connecting block 104 fixedly installed on it drives the positioning tube 105 and the limiting block 109 installed on the outside of the positioning tube 105 and inserted into the limiting groove 2 on one side of the inner wall of the rotating groove 102 to move together. The movement causes the positioning tube 105, under the physical guidance and constraint of the trajectory of the limiting groove 2, to gradually deflect 90 degrees downward from the initial high vertical waiting state to the horizontal state, and finally approach the food flow on the surface of the transport belt 403. At this time, the rotary motor 108 installed on the side of the positioning tube 105 starts, and its output end drives the collection tube 106, which is rotated and installed inside the positioning tube 105, to rotate, so that the collection port 107 on the outer surface of the collection tube 106 scoops into the material flow like a spoon to collect the sample. Then the rotary motor 108 rotates in the opposite direction to drive the collection tube 106 to reset and close the collection port 107 to lock the sample.

[0050] Subsequently, the electric telescopic rod 201 extends, pushing the deflection block 206 back in the opposite direction, causing the deflection rod 103 to rotate in the opposite direction. This causes the positioning tube 105 to deflect upward and return to its initial vertical position via the connecting block 104. At this time, the outlet at the bottom of the positioning tube 105 is aligned with the upper inlet of the filling tube 203 below. The leak-proof plate 202 fixed on one side of the rotating block 101 plays a role in preventing material spillage during this process. The rotary motor 108 starts again to drive the collection tube 106 to rotate and open the collection port 107, allowing the internal sample to fall into the filling tube 203 under gravity and pass through the filling tube 203, finally falling into the bottom of the packaging film pre-fitted at the bottom of the filling tube 203.

[0051] Next, the automatic film feeding and sealing process begins. The stepper motor 304, mounted on the outside of the setting block 3, starts, driving the circular array of universal joints 301 on the inner wall of the setting block 3 to rotate via the track shaft 305 and drive track 303 mounted on the output end. This array consists of several universal joints 301 connected end-to-end by ball shafts to form a closed loop around the filling tube 203. The inner side of the rubber wheel 302 on each universal joint 301 presses tightly against the packaging film surface at the lowest end of the filling tube 203. As the closed loop of the universal joints 301 revolves around the filling tube 203, the rubber wheel 302 grips the outer surface of the packaging film using friction, overcoming the resistance of the rotating block 101 mounted above. The damping force applied by the limiting ring 205 in the threaded groove 204 on the bottom end precisely pulls the outermost packaging film down along the filling tube 203 by a predetermined bag length, creating a new packaging space for the next sampling. Subsequently, the two cylinders 306 installed on both sides below the discharge port of the filling tube 203 on the bottom surface of the setting block 3 act simultaneously. The extended ends of the cylinders 306 push the electric heating plates 307 connected to them closer together and clamp the upper opening of the just pulled-down film bag. The two electric heating plates 307 make contact with each other and melt and seal the plastic film through instantaneous high temperature heating, thereby completing an automated production and packaging process for an independent and sealed food testing sample.

[0052] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
