Description

Technical Field

[0001] This application relates to the field of rice noodle production equipment, and more particularly to a weighing and portioning device for extruded grain products. Background Technology

[0002] Grain products include vermicelli, rice noodles, etc. As the rice vermicelli industry develops, it is gradually shifting from large-scale distribution packaging to small-quantity packaging. For continuous production lines of rice and flour grain products formed by extruders, product line fluctuations are a difficult problem to solve due to the many production factors that affect extrusion stability. The fluctuation characteristics are the main difficulty for accurate measurement in weighing and portioning.

[0003] Chinese patent CN218959982U discloses an automated rice noodle production line that uses a fixed-length cutting method. However, due to the uneven density of the extruded product, the fixed-length cutting method will lead to weight deviation. If the product is cut into portions by weight, the cumulative error caused by the different speeds of the extrusion outlets will result in uneven lengths, affecting the product shape.

The portioning cutter has multiple blades arranged in parallel to cut the entire grain product into multiple strands. The flattening roller is located above the receiving end of the first conveyor line, and the grain product passes through the gap between the flattening roller and the receiving end. The comb is located above the first conveyor line and is used to comb the grain product that has been cut into multiple strands.

[0007] Preferably, in a predetermined direction, a suspended section is provided between the discharge end of the first conveyor line and the second conveyor line, and a monitoring mechanism is provided in the suspended section to monitor the cumulative error of the grain products.

[0008] Preferably, the monitoring mechanism includes a swing conveyor line and a third photoelectric sensor; one end of the swing conveyor line is connected to the discharge end of the first conveyor line, and the second end of the swing conveyor line can swing up and down; a third photoelectric sensor is provided on the lower side of the feed end of the second conveyor line, and the third photoelectric sensor is used to monitor the sagging height of the grain products caused by the cumulative error of the grain products in the suspended section.

[0009] Preferably, the monitoring mechanism includes a swing conveyor line, an elastic connector, and a fourth photoelectric sensor; the first end of the swing conveyor line is hinged to the discharge end of the first conveyor line, and the second end of the swing conveyor line is connected to the receiving end of the second conveyor line through the elastic connector; the grain products on the first conveyor line are conveyed to the second conveyor line via the swing conveyor line; the fourth photoelectric sensor is set on the horizontal side of the swing conveyor line and is used to monitor the swing amplitude of the swing conveyor line caused by the cumulative error of the grain products.

[0010] Preferably, the monitoring mechanism includes a lifting conveyor line, a support frame, a weighing module, and a lifting component connected sequentially along the height direction. The grain products on the first conveyor line are conveyed to the second conveyor line via the lifting conveyor line, and the lifting component is used to drive the lifting conveyor line, the support frame, and the weighing module to move in the height direction.

[0011] Preferably, a second cutter and a second telescopic member are provided above the first conveyor line. The second telescopic member is connected to the second cutter and is used to drive the second cutter to cut the grain products on the first conveyor line. The second telescopic member is electrically connected to the monitoring mechanism.

[0012] Preferably, the clamping assembly includes a movable plate, a soft roller, and a third telescopic member; one end of the movable plate is hinged to the discharge end of the second conveyor line, and a channel for the grain products to pass through is formed between the soft roller and the surface of the movable plate; the third telescopic member is hinged to the discharge end of the second conveyor line and the movable plate respectively, and is used to push the movable plate closer to the soft roller and away from the soft roller.

[0013] Preferably, along a predetermined direction, the first cutter is disposed on the rear side of the soft roller, and the first cutter is connected to the first telescopic member. The first telescopic member drives the first cutter to move toward the movable plate and cut the grain product.

[0015] The weighing and portioning device of this application has at least the following beneficial effects: In this application, long, continuous grain products sequentially pass through a first conveyor line, a second conveyor line, a clamping assembly, and are conveyed along a predetermined direction on a third conveyor line. When the weight of the grain products on the third conveyor line approaches a set weight value, the speed of the second conveyor line slows down. Simultaneously, the first photoelectric sensor of the photoelectric monitoring group monitors the length of the grain products on the third conveyor line. Once the length of the grain products reaches the target, the clamping assembly clamps the grain products, and the third conveyor line stops conveying. At this point, the weighing process switches from dynamic to static. If the difference between the weight of the grain products on the third conveyor line and the set weight value is within the allowable error range, the first cutter cuts the grain products. The cut section of grain product is conveyed forward along the third conveyor line to the target position. If it is not within the allowable range, the clamping component releases the grain product, and then the third conveyor line continues to convey the grain product forward to replenish its weight. After replenishment, the grain product is clamped and cut again. If the second photoelectric sensor generates a sensing signal during replenishment, it indicates that this section of grain product is too long and underweight. After the clamping component clamps the grain product, the first cutter cuts the grain product. The unqualified grain product section located on the third conveyor line is conveyed backward by the third conveyor line to the rework hopper. Compared with manual weighing or fixed-length cutting, this application can take into account both weight and length control, resulting in higher production efficiency. Attached Figure Description

[0017] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0018] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0019] Example 1: like Figure 1 As shown, this embodiment discloses a weighing and portioning device for extruded grain products. This device is generally located at the rear end of the grain product extrusion nozzle and is used to weigh and portion the grain product L. In this embodiment, extruded grain products refer to grain products obtained by extruding grain materials using an extruder, such as rice noodles, vermicelli, etc.

[0020] like Figure 1 As shown, the weighing and portioning equipment includes a first conveyor line 100, a second conveyor line 200, and a third conveyor line 300 arranged sequentially along a predetermined direction. The weighing and portioning equipment for extruded grain products also includes a clamping assembly 400 and a first cutter 500 arranged between the second conveyor line 200 and the third conveyor line 300, a weighing assembly 600 arranged on the third conveyor line 300, and a photoelectric monitoring group 700 arranged above the third conveyor line 300. The conveyor lines are used to drive the grain product L to move in a predetermined direction. The predetermined direction can be understood as the direction of movement of the grain product L or the direction in which the grain product L is pulled. In this embodiment, the left and right horizontal directions are configured as the predetermined direction.

[0021] like Figure 1 As shown, the left end of the first conveyor line 100 is configured as a receiving end, which corresponds to the external extruder 1100. The extruder 1100 extrudes the grain product material from the grain product extrusion port. The extruded grain product material falls onto the receiving end of the first conveyor line 100 and is then conveyed outward by the first conveyor line 100, the second conveyor line 200, and the third conveyor line 300. The extruder 1100 for extruded grain product material is existing technology and will not be described in detail here.

[0022] like Figure 1As shown in the preferred embodiment, the weighing and portioning device for extruded grain products further includes an upper limit member 110, a lower limit member 120, a portioning cutter 130, a flattening roller 140, and a comb 150 arranged sequentially along a predetermined direction. The upper limit member 110 and the lower limit member 120 are used to limit the height of the grain product material extruded from the grain product extrusion port, so that the grain product material falls smoothly onto the first conveyor line 100. The portioning cutter 130 is used to cut a whole piece of grain product L into multiple parallel strands of grain product L. The flattening roller 140 is used to flatten the divided grain product L. The comb 150 is used to comb the flattened grain product L, that is, to sort the material. The specific positional relationship is as follows: like Figure 1 As shown, the upper limit member 110 is disposed on the outside of the first conveyor line 100 along a predetermined direction. The grain product L from the grain product extrusion port passes through the upper limit member 110, and the height of the grain product L is limited by the upper limit member 110. Furthermore, the upper limit member 110 is rotatably provided with an upper limit roller, and the grain product L is disposed on the lower side of the upper limit roller, and the height of the grain product L is limited by the upper limit roller.

[0023] like Figure 1 As shown, the lower limit member 120 is located at the upper end of the left side of the first conveyor line 100. The grain product L, which passes through the upper limit member 110, contacts and slides over the outer periphery of the lower limit member 120. The lower limit member 120 limits the drop height of the grain product L. Furthermore, the lower limit member 120 includes a rolling lower limit roller. The grain product L contacts and slides relative to the upper circumferential portion of the lower limit roller. In this embodiment, through the cooperation of the upper limit member 110 and the lower limit member 120, the height of the grain product material extruded from the grain product extrusion port is limited to a predetermined height, which is slightly higher than the height of the first conveyor line 100, for example, 5cm-20cm higher. By limiting the connection height between the grain product L and the first conveyor line 100, the grain product L can smoothly transition onto the first conveyor line 100.

[0024] like Figure 1 and Figure 2 As shown, the slitting cutter 130 is used to cut the thin-sheet grain product L into parallel multi-strand strips. The slitting cutter 130 includes multiple blades, which are arranged side by side at intervals in the horizontal width direction of the first conveyor line 100, with the blades facing the incoming grain product L, and the cutting edge of the blades facing the grain product L to slit it.

[0025] like Figure 1As shown, the flattening roller 140 is disposed above the receiving end of the first conveyor line 100. There is a gap between the circumferential surface of the flattening roller 140 and the upper surface of the first conveyor line 100 in the height direction. The divided grain product L passes through the gap in a predetermined direction. The rotating flattening roller 140 flattens the grain product L when it passes through the gap.

[0026] like Figure 1 As shown, the comb 150 is located behind the flattening roller 140. The flattened multi-strand material passes through the gap in the middle of the comb 150, so that the comb 150 combs the multi-strand material, and the combed grain product L is conveyed forward.

[0027] like Figure 1 As shown, the clamping assembly 400 is disposed between the second conveyor line 200 and the third conveyor line 300, wherein the second conveyor line 200 is higher than the third conveyor line 300, and the clamping assembly 400 is located between the second conveyor line 200 and the third conveyor line 300 along the height direction.

[0028] like Figure 1 As shown, the clamping assembly 400 can be configured as an existing cylinder finger or the structure described in this embodiment. In this embodiment, the clamping assembly 400 includes a movable plate 410, a soft roller 420, and a third telescopic member 430.

[0029] like Figure 1 As shown, one end of the movable plate 410 is hinged to the discharge end of the second conveyor line 200. Specifically, the movable plate 410 is hinged to the second frame 210 below the discharge end. After the hinge is completed, the movable plate 410 can swing around the horizontal direction to change the angle. The material extending forward from the discharge end of the second conveyor line 200 naturally falls onto the plate surface of the movable plate 410. When the movable plate 410 changes its angle, it can drive the grain product L on the movable plate 410 to swing.

[0030] like Figure 1 As shown, the soft roller 420 is rotatably mounted on one side of the movable plate 410. The grain product L passes between the movable plate 410 and the soft roller 420. If it is necessary to clamp the grain product L, the grain product L on the surface of the movable plate 410 moves toward the soft roller 420 under the drive of the third telescopic member 430. The grain product L located between the movable plate 410 and the soft roller 420 is clamped between the movable plate 410 and the soft roller 420.

[0031] like Figure 1As shown, the fixed end of the third telescopic member 430 is hinged to the discharge end of the second conveyor line 200. Specifically, the third telescopic member 430 is hinged to the second frame 210 below the discharge end. The telescopic end of the third telescopic member 430 is hinged to the back side of the movable plate 410. When the third telescopic member 430 extends, it can drive the movable plate 410 to rotate toward the soft roller 420 and thus clamp the grain product L. Conversely, when the third telescopic member 430 retracts, the movable plate 410 moves away from the soft roller 420 and thus releases the grain product L. In this embodiment, the third telescopic member 430 is configured as a linear drive component such as an electric push rod or a telescopic cylinder.

[0032] like Figure 1 As shown, the weighing component 600 is disposed on the third conveyor line 300 and is used to weigh the grain product L on the third conveyor line 300. In the prior art, a weighing mechanism is set on the conveyor line, which is the prior art. In this embodiment, preferably, the weighing component 600 includes a weighing sensor 610 and a torque sensor 620. The third conveyor line 300 is a belt conveyor line. The weighing sensor 610 is disposed on the lower surface of the belt of the third conveyor line 300. The grain product L is conveyed forward from the upper surface of the belt. The weighing sensor 610 located on the lower surface of the belt weighs the grain product L on the upper surface of the belt. The torque sensor 620 is disposed on the belt of the third conveyor line 300 and is used to detect the tension of the belt of the third conveyor line 300. In this embodiment, the accurate weighing result is obtained by measuring static data by the weighing sensor 610 and combining it with the tension data. For example, the tension data is converted according to the conversion formula to obtain the deviation weight. The deviation weight is added to the static weighing result to obtain the weighing result. In addition, the weighing component 600 in this embodiment can be a weighing mechanism used on a belt conveyor in the prior art, or the third conveyor line 300 can be configured as an existing conveyor line with weighing function, both of which are feasible.

[0033] like Figure 1 As shown, the photoelectric monitoring group 700 includes a first photoelectric sensor 710 and a second photoelectric sensor 720. The first photoelectric sensor 710 and the second photoelectric sensor 720 are arranged at a predetermined interval above the third conveyor line 300. The position of the first photoelectric sensor 710 is configured to be close to one side of the second conveyor line 200. The monitoring direction of the first photoelectric sensor 710 and the second photoelectric sensor 720 is configured to be vertically downward. When the first photoelectric sensor 710 detects the end of the grain product L, it indicates that the length of the grain product L on the third conveyor line 300 has reached the required length. When the second photoelectric sensor 720 detects the end of the grain product L, it indicates that the length of the grain product L on the third conveyor line 300 has reached an unacceptable length. At this time, it is necessary to cut off the grain product L and reverse the grain product L on the third conveyor line 300 to the rework hopper 1200.

[0034] In this embodiment, the interval between the first photoelectric sensor 710 and the second photoelectric sensor 720 is the control threshold for the cutting length deviation of the grain product L. The position and interval between the first photoelectric sensor 710 and the second photoelectric sensor 720 can be adjusted according to actual needs to control the cutting position of the grain product L.

[0035] like Figure 3 As shown in the preferred embodiment, the weighing and portioning equipment for extruded grain products further includes a monitoring mechanism. In a predetermined direction, a suspended section 100a is provided between the discharge end of the first conveyor line 100 and the second conveyor line 200. The monitoring mechanism is located within the suspended section 100a and is used to monitor the cumulative error of the grain product L caused by the fluctuation characteristics of the material.

[0036] like Figure 3 As shown, in a predetermined direction, the discharge end of the first conveyor line 100 and the feed end of the second conveyor line 200 are spaced apart, so that a suspended section 100a is formed between the discharge end of the first conveyor line 100 and the feed end of the second conveyor line 200. The distance between the discharge end of the first conveyor line 100 and the feed end of the second conveyor line 200 (i.e., the length of the suspended section 100a) is designed according to actual needs. In this embodiment, it is preferably 15cm to 50cm, such as 20cm, 25cm, 30cm, etc.

[0037] like Figure 3 As shown, the monitoring mechanism includes a swing conveyor line 810 and a third photoelectric sensor 820. The left end of the swing conveyor line 810 is hinged to the discharge end of the first conveyor line 100, specifically to the first frame below the discharge end of the first conveyor line 100. The right end of the swing conveyor line 810 can swing up and down. When the swing conveyor line 810 swings upward to be flush with the feed end of the second conveyor line 200, the swing conveyor line 810 is in a bridging position, and the grain product material can be conveyed forward through the first conveyor line 100, the swing conveyor line 810, and the second conveyor line 200. Here, the swing conveyor line 810 refers to an existing swing conveyor.

[0038] like Figure 3 As shown, the third photoelectric sensor 820 is mounted on the second frame 210 below the second conveyor line 200. The third photoelectric sensor 820 and the right end of the swing conveyor line 810 are located on the same side. The third photoelectric sensor 820 is used to detect the height of the grain product L hanging freely in the suspended section 100a. Specifically, the third photoelectric sensor 820 is mounted on the second frame 210 below the second conveyor line 200, and the monitoring direction of the third photoelectric sensor 820 is configured to be horizontal, that is, a predetermined direction. The height position of the third photoelectric sensor 820 is selected according to actual needs. In this embodiment, the height difference between the third photoelectric sensor 820 and the upper surface of the first conveyor line 100 is preferably 5cm to 15cm, for example, 5cm to 8cm.

[0039] like Figure 3 As shown, in this preferred embodiment, the weighing and portioning device for extruded grain products further includes a second cutter 900 and a second telescopic member 910. The second cutter 900 is positioned directly above the first conveyor line 100 and behind the comb 150 along a predetermined direction. The telescopic end of the second telescopic member 910 is connected to the second cutter 900, and the second cutter 900 is moved vertically by the second telescopic member 910, thereby cutting the grain product L on the first conveyor line 100. The second telescopic member 910 is configured as a conventional electric push rod, telescopic cylinder, etc. The second telescopic member 910 is electrically connected to the monitoring mechanism, specifically to the third photoelectric sensor 820 of the monitoring mechanism.

[0040] like Figure 4 As shown, the weighing and portioning equipment for extruded grain products in this embodiment also includes a control unit 1000. The control unit 1000 is electrically connected to the first conveyor line 100, the second conveyor line 200, the third conveyor line 300 and the swing conveyor line 810 respectively, and is used to control the forward and reverse conveying of the four conveyor lines. The control unit 1000 is also electrically connected to the first photoelectric sensor 710, the second photoelectric sensor 720, the third photoelectric sensor 820, the first telescopic member 510, the second telescopic member 910, the third telescopic member 430, the weighing sensor 610 and the torque sensor 620.

[0041] The working principle of this embodiment is as follows: like Figure 3 As shown, the right end of the swing conveyor line 810 swings upward until it is flush with the second conveyor line 200. Then, the control unit 1000 sends signals to the first conveyor line 100, the second conveyor line 200, the third conveyor line 300, and the swing conveyor line 810. The four conveyor lines transport the grain product L in a predetermined direction. When the grain product L moves onto the third conveyor line 300, the control unit 1000 controls the right end of the swing conveyor line 810 to swing downward until it is close to a vertical state. like Figure 3As shown, the weighing sensor 610 measures the weight of the grain product L on the third conveyor line 300 in real time. When the weight of the grain product L approaches the set weight value, for example, when it reaches 80% of the set weight value, the control unit 1000 sends a signal to the second conveyor line 200, and the second conveyor line 200 reduces its speed, for example, to 10% to 20% of the normal speed. When the end of the grain product L slowly moves on the third conveyor line 300 to below the first photoelectric sensor 710, the first photoelectric sensor 710 generates a signal. The control unit 1000 receives the signal and sends a signal to the third telescopic member 430. The third telescopic member 430 drives the movable plate 410 to move toward the soft roller 420 and clamp the grain product L. At the same time, the control unit 1000 sends a signal to the third conveyor line 300, and the third conveyor line 300 stops conveying. The grain product L changes from dynamic weighing to static weighing. The control unit 1000 acquires the weighing data from the weighing sensor 610 and the tension data from the torque sensor 620. The weighing data and the tension data are combined and converted to obtain the final weight of the grain product L. If the weight of the grain product L is within the error range from the set weight value, the control unit 1000 sends a signal to the first telescopic member 510, and the first cutter 500 cuts the grain product L. The control unit 1000 then sends signals to the first telescopic member 510, the third telescopic member 430 and the third conveyor line 300 respectively, so that the first cutter 500 retracts, the movable plate 410 releases the grain product L, and the third conveyor line 300 conveys the cut grain product L forward to the predetermined position. If the weight of the grain product L is not within the error range of the set weight value, the control unit 1000 sends a signal to the third telescopic member 430 and the third conveyor line 300, so that the movable plate 410 releases the grain product L, and the third conveyor line 300 drives the grain product L to continue to move forward and automatically and accurately replenish the weight according to the program conversion result. If the second photoelectric sensor 720 generates a signal during the weight replenishment process, it indicates that the maximum allowable length has been exceeded and the weight cannot be replenished. At this time, the control unit 1000 sends signals to the third telescopic component 430, the third conveyor line 300, and the first telescopic component 510, so that after the grain product L is clamped, the first cutter 500 cuts the grain product L. The control unit 1000 then sends a signal to the third conveyor line 300, and the third conveyor line 300 reverses the conveying process, thereby conveying the oversized and underweight grain product L in reverse to the rework hopper 1200.

[0042] According to the process described above, the conveyed grain product L is cut into segments in sequence. During the process, the monitoring agency monitors the cumulative error of the grain product L and indirectly controls the operation of the second cutter 900 as needed.

[0043] In this embodiment, the working principle of the monitoring mechanism is as follows: After running for a period of time, due to the material characteristics, some of the grain products L in the suspended section 100a are in a natural hanging state. When the grain product L hangs down to correspond with the third photoelectric sensor 820, the third photoelectric sensor 820 generates a signal. After receiving the signal, the control unit 1000 sends a signal to the second telescopic member 910 so that the second cutter 900 cuts the grain product L on the first conveyor line 100. Due to gravity, the cut-off portion of the grain product L falls from below the suspended section 100a into the rework hopper 1200. Then, the control unit 1000 controls the right end of the swing conveyor line 810 to swing upward, bridging within the suspended section 100a (e.g., ...). Figure 5 As shown), the grain product L on the first conveyor line 100 continues to be conveyed to the third conveyor line 300 via the forward swing conveyor line 810 and the second conveyor line 200. Then the control unit 1000 controls the right end of the swing conveyor line 810 to swing downward. This embodiment of monitoring the cumulative error of grain product L is mainly applicable to grain product materials that have already undergone shaped processing. The self-weight of the designed cumulative error will not stretch or deform the material. This material only needs to be overlapped by the swing conveyor line 810 at the beginning. After the material is transported to the second conveyor line 200 at the rear end, the swing conveyor line 810 opens downwards, and the material hangs down naturally. All cumulative errors will be manifested by natural hanging due to their own weight in the suspended section 100a. The front and rear conveyor lines of the suspended section 100a only need to process the material evenly. When the cumulative error reaches the set value, the material in the front section is cut off and collected as rework material. At this time, the conveyor line is no longer continuous. Then the swing conveyor line 810 swings upwards to the bridging position and re-transports the material to the second conveyor line 200 at the rear end. The whole process does not require manual intervention and has high work efficiency.

[0044] Example 2 like Figure 6 As shown, the monitoring mechanism in this second embodiment is different from that in the first embodiment. The monitoring mechanism in this second embodiment is mainly used for cumulative errors caused by product line fluctuations, and for cases where grain products have not undergone shaping processing in the previous process.

[0045] like Figure 6 As shown, the monitoring mechanism in this second embodiment includes a swing conveyor line 810, an elastic connector 830, and a fourth photoelectric sensor 840, as detailed below: The left end of the oscillating conveyor 810 is hinged to the discharge end of the first conveyor 100, specifically to the first frame below the discharge end of the first conveyor 100. The oscillating conveyor 810 can freely rotate up and down around the hinged position with the first frame without any other constraints. The right end of the oscillating conveyor 810 is connected to the feed end of the second conveyor 200 through an elastic connector 830. The elastic connector 830 is configured as a spring, with one end connected to the right end of the oscillating conveyor 810 and the other end connected to the feed end of the second conveyor 200. The first conveyor 100, the oscillating conveyor 810, and the second conveyor 200 work together to convey the grain product L forward.

[0046] like Figure 6 As shown, the fourth photoelectric sensor 840 is mounted on the second frame 210 below the second conveyor line 200. The fourth photoelectric sensor 840 is located on the same side as the right end of the swing conveyor line 810 and is used to detect the swing amplitude of the right end of the swing conveyor line 810. Specifically, the fourth photoelectric sensor 840 is mounted on the second frame 210 below the second conveyor line 200, and the monitoring direction of the fourth photoelectric sensor 840 is configured to be horizontal, i.e., a predetermined direction. The height of the fourth photoelectric sensor 840 is selected according to actual needs. In this embodiment, the height difference between the fourth photoelectric sensor 840 and the upper surface of the first conveyor line 100 is preferably 5cm to 15cm, for example, 5cm to 8cm.

[0047] like Figure 7 As shown, the control unit 1000 is electrically connected to the first conveyor line 100, the second conveyor line 200, the third conveyor line 300 and the swing conveyor line 810 respectively, and is used to control the forward and reverse conveying of the four conveyor lines. The control unit 1000 is also electrically connected to the first photoelectric sensor 710, the second photoelectric sensor 720, the fourth photoelectric sensor 840, the first telescopic member 510, the second telescopic member 910, the third telescopic member 430, the weighing sensor 610 and the torque sensor 620.

[0048] The working principle of the monitoring mechanism in Example 2 is as follows: like Figure 8As shown, due to the cumulative error caused by material fluctuations, a small amount of grain product L accumulates on the oscillating conveyor line 810. The weight of the accumulation stretches the elastic connector 830. As the weight of the accumulation increases, the right end of the oscillating conveyor line 810 gradually swings downward. When the right end of the oscillating conveyor line 810 corresponds to the fourth photoelectric sensor 840 and the fourth photoelectric sensor 840 generates a signal, the control unit 1000 receives the signal from the fourth photoelectric sensor 840 and controls the second extension to drive the second cutter 900 to move downward, cutting the grain product L on the first conveyor line 100. The cut section of grain product L is transported to the rework hopper 1200 under the action of gravity and the oscillating conveyor line 810. After the cut section of grain product enters the rework hopper 1200, the oscillating conveyor line 810 swings upward again to the initial position under the reset action of the elastic connector 830. The grain product L on the first conveyor line 100 continues to be transported forward along the first conveyor line 100, the oscillating conveyor line 810, and the second conveyor line 200.

[0049] The monitoring mechanism in this embodiment is mainly used for grain products that have not undergone formal processing. The cumulative error causes the weight to gradually increase, and the downward swing of the swing conveyor 810 also gradually increases. The method of judging the cumulative error is different from that of materials that fall naturally, that is, it is done through the cooperation of the elastic connector 830 and the fourth photoelectric sensor 840.

[0050] Example 3 like Figure 9 As shown, the monitoring mechanism in this embodiment three is different from that in embodiment one. The monitoring mechanism in this embodiment three is mainly used for cumulative errors caused by product line fluctuations, and for cases where grain products have not undergone shaping processing in the previous process.

[0051] The monitoring mechanism in this embodiment includes a lifting conveyor line 850, a support frame 860, a weighing module 870, and a lifting assembly 880. The lifting conveyor line 850 is located within the suspended section 100a. The support frame 860 is connected to the lifting conveyor line 850. The lower end of the support frame 860 is connected to the weighing module 870. The weighing module 870 is located at the upper end of the lifting assembly 880. The lifting assembly 880 can be an existing proportional adjustment telescopic mechanism or other existing telescopic components.

[0052] The first conveyor line 100, the lifting conveyor line 850, and the second conveyor line 200 work together to transport the grain product L forward.

[0053] like Figure 10As shown, the control unit 1000 is electrically connected to the first conveyor line 100, the second conveyor line 200, the third conveyor line 300, and the lifting conveyor line 850, respectively, and is used to control the forward and reverse conveying of the four conveyor lines. The control unit 1000 is also electrically connected to the first photoelectric sensor 710, the second photoelectric sensor 720, the first telescopic component 510, the second telescopic component 910, the third telescopic component 430, the weighing sensor 610, the torque sensor 620, the weighing module 870, and the lifting assembly 880.

[0054] The working principle of the monitoring agency in Example 3 is as follows: like Figure 11 As shown, due to the cumulative error caused by material fluctuations, a small amount of grain product L accumulates on the lifting conveyor line 850. The weighing module 870 weighs the grain product L on the lifting conveyor line 850. The control unit 1000 receives the weight data from the weighing module 870. When the weight data reaches the set threshold, the control unit 1000 controls the second extension to drive the second cutter 900 to move downward, cutting the grain product L on the first conveyor line 100. The lifting component 880 actively or passively drives the lifting conveyor line 850 to descend. After descending, the control unit 1000 controls the lifting conveyor line 850 to transport the cut section of grain product L to the rework hopper 1200. Then, the lifting component 880 actively or passively drives the lifting conveyor line 850 to rise to the initial height. The grain product L on the first conveyor line 100 continues to be transported forward along the first conveyor line 100, the lifting conveyor line 850, and the second conveyor line 200.

[0055] The monitoring mechanism in this embodiment is mainly used for grain products that have not undergone standardized processing. The cumulative error causes the weight to gradually increase. The weighing module 870 weighs the grain products L piled on the lifting conveyor line 850 in real time. Once the weight reaches the standard, the second cutter 900 is triggered to cut off the cumulative error segment. The whole process does not require manual intervention and is highly efficient.

[0056] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
