[0042] The present invention proposes a shaping mechanism, which is applied to an online detection system. Specifically, Figure 1As shown, the online detection system includes a feeding system and a detector distributed along the upstream and downstream. The feeding system includes a frame 100, a hopper 700, a conveyor belt and a shaping mechanism. The hopper 700 is installed on the frame 100 to feed the object to be detected. The conveyor belt is located below the hopper 700 and is used to transport the object to be detected. The shaping mechanism is installed on the frame 100 and is located downstream of the hopper 700. The object to be detected is fed from the hopper 700 and then unloaded onto the conveyor belt. The conveyor belt transports the object to be detected downstream. The object to be detected first passes through the shaping mechanism and is shaped into a certain shape for detection by the detector, thereby ensuring the accuracy of the detection result. Among them, the shaping mechanism can be applied to the coal mining industry or the salt mining industry to shape coal powder or salt powder. The detector includes one or more of a moisture detector, an element detector for detecting ash or sulfur content, and a calorific value detector. The detector can use an XRF (X Ray Fluorescence, X-ray fluorescence spectrometry) detector. 、 NIRS (Near Infrared Spectrum Instrument) and so on.

[0043] In one embodiment of the present invention, Figures 1 to 4 As shown, the shaping mechanism includes a pressure roller 200 rotatably disposed on the frame 100 and a driving device 300 drivingly connected to the pressure roller 200, the pressure roller 200 is located above the conveyor belt, and a rolling surface 210 is formed on the outer periphery of the pressure roller 200, and the linear speed of the rolling surface 210 and the adjacent side of the conveyor belt are the same.

[0044] In the technical solution of the present invention, the rolling surface 210 is a circumferential surface, and the rotation direction of the pressure roller 200 is opposite to that of the conveyor belt, so that the linear speeds of the rolling surface 210 and the conveyor belt on adjacent sides have the same direction, and the driving device 300 can be a motor or a cylinder, and the rotation speed of the pressure roller 200 is controlled by the driving device 300, so that the magnitude of the linear speed of the rolling surface 210 is equal to the magnitude of the linear speed of the conveyor belt. In this way, when the rolling surface 210 flattens the object to be detected, the position where the rolling surface 210 contacts the object to be detected can maintain the same linear speed as the object to be detected, so that the linear speeds of the upper and lower surfaces of the object to be detected are equal, and the object to be detected will not be dragged by the rolling surface 210 in the conveying direction, which is conducive to avoiding cracks on the outer surface of the object to be detected, thereby improving the flatness after shaping, so as to ensure the accuracy of the detector in detecting the object to be detected.

[0045] It can be understood that the difference between the linear velocity of the rolling surface 210 and the linear velocity of the conveyor belt satisfies the allowable error range, and it can be considered that the linear velocity of the rolling surface 210 is equal to the linear velocity of the conveyor belt. That is, the directions of the linear velocities of the two may not be exactly the same, and the magnitudes do not need to be completely equal. The linear velocities of the two are close, which can also meet the flatness requirements of shaping.

[0046] Further, in this embodiment, the shaping mechanism includes a plurality of the pressing rollers 200, and the plurality of the pressing rollers 200 are spaced apart along the conveying direction of the conveyor belt, and in the conveying direction, the height difference between the rolling surface 210 of each of the pressing rollers 200 and the conveyor belt gradually decreases. Wherein, a plurality refers to more than two. In this embodiment, the rolling surface 210 of the pressing roller 200 located further downstream is set lower and closer to the conveyor belt, so that the object to be detected can be rolled step by step, which is conducive to improving the flatness after shaping. It can be understood that since the rolling surface 210 has a certain linear speed, the contact time between the rolling surface 210 of a single pressing roller 200 and the object to be detected is limited. If a single pressing roller 200 is set, in order to ensure the flattening effect, the speed of the conveyor belt needs to be slow enough, resulting in the detection efficiency being affected. In this embodiment, by setting a plurality of pressing rollers 200, multi-stage rolling is achieved, which can ensure the flatness of the object to be detected while improving the transmission speed of the conveyor belt, thereby ensuring the detection accuracy and detection efficiency at the same time. The height difference between two adjacent pressing rollers 200 is preferably less than 10 mm, so that the height of the object to be detected will not exceed the flattening amount that can be achieved by a single pressing roller 200, which is conducive to ensuring the flatness of the object to be detected.

[0047] Optionally, the driving device can be connected to different pressing rollers through different transmission components, or multiple pressing rollers can be connected through transmission components, and the driving device is connected to one of the pressing rollers. The transmission components can be gears, belts, chains, etc. In this way, multiple pressing rollers can be driven to rotate simultaneously through one driving device, realizing linkage between multiple pressing rollers and avoiding accumulation of objects to be detected due to a single pressing roller.

[0048] Furthermore, in this embodiment, if Figure 4As shown, the pressure roller 200 also has two limiting surfaces 220 respectively connected to the two ends of the rolling surface 210, and the limiting surfaces 220 extend outwardly from the rolling surface 210 in the circumferential direction, and the distance between the two limiting surfaces 220 is greater than or equal to the width of the rolling surface 210. Among them, the outer periphery of the limiting surface 220 is set close to the conveyor belt, and there can be a certain matching gap between the two, or it can be a contact match. In this embodiment, the height of the object to be detected will be limited by the distance between the rolling surface 210 and the conveyor belt, and the width of the object to be detected will be limited by the distance between the two limiting surfaces 220. Under the action of the pressure roller 200, the object to be detected can fill the space jointly constructed by the rolling surface 210, the two limiting surfaces 220 and the conveyor belt to form a regular shape to prevent the object to be detected from extending outward. Of course, in other embodiments, it can also be that baffles are set on both sides of the conveyor belt, and the width of the rolling surface 210 is adapted to the width setting of the conveyor belt, and the baffles are used to prevent the object to be detected from extending outward.

[0049] Furthermore, in this embodiment, if Figure 4 As shown, the limiting surface 220 is set as a conical surface. That is, the projection of the limiting surface 220 in the axial direction of the pressure roller 200 is in a circular ring shape, and the two limiting surfaces 220 are gradually expanded in the direction away from each other. In this way, the limiting surface 220 is in a curved surface shape, and the contact area with the object to be detected is small, and it is not easy to affect the flatness of the object to be detected. Of course, in other embodiments, the limiting surface 220 can also be set to a plane shape, that is, the distance between the two limiting planes of the pressure roller 200 in the axial direction is equal everywhere.

[0050] In particular, between the multiple rollers 200, the width of the rolling surface 210 is equal, and the inclination angle of the limiting surface 220 is also equal, so that the height of the space formed between the multiple rollers 200 and the conveyor belt gradually decreases along the conveying direction, and the width remains roughly unchanged. In this way, the object to be detected can be gradually compacted after multiple levels of rolling, and the flatness of the surface is not easily damaged, which is conducive to ensuring the accuracy of the detection result. It should be noted that for the roller 200 whose rolling surface 210 is closer to the conveyor belt, the outer diameter of the limiting surface 220 can be adaptively reduced, so that the distance between the outer periphery of the limiting surface 220 and the conveyor belt remains unchanged, and does not interfere with the conveyor belt.

[0051] In one embodiment, the shaping mechanism further includes a rough shaping member disposed upstream of the pressing roller 200, and the rough shaping member is used to shape the material on the conveyor belt into a material pile suitable for rolling by the pressing roller 200. In this way, the rough shaping member can be used to perform preliminary shaping on the object to be inspected, so as to facilitate rolling by the pressing roller 200, which is beneficial to ensure the flatness of the object to be inspected after rolling.

[0052] In one embodiment, if Figure 2As shown, the rough shaping member includes two width-limiting baffles 400, which are respectively arranged corresponding to the two sides of the conveyor belt. At least on the side close to the pressure roller 200, the distance between the two width-limiting baffles 400 is smaller than the distance between the two limiting surfaces 220 of the pressure roller 200. It can be understood that a guide channel 410 is formed between the two width-limiting baffles 400, and the object to be detected will be transported to the downstream pressure roller 200 through the guide channel 410. The distance between the two width-limiting baffles 400 on the side close to the pressure roller 200 is smaller than the distance between the two limiting surfaces 220, that is, the width of the outlet of the guide channel 410 is smaller than the width between the two limiting surfaces 220. In this way, the object to be detected that reaches the pressure roller 200 can be completely accommodated in the space constructed by the pressure roller 200 and the conveyor belt, and the space also has a margin for the object to be detected that rolls down after rolling, which is conducive to ensuring the rolling effect of the pressure roller 200 on the object to be detected. In this embodiment, the width of the object to be inspected is preliminarily shaped by two width-limiting baffles 400 so that the width of the object to be inspected is suitable for rolling by the pressing roller 200, thereby ensuring the flatness of the object to be inspected after rolling.

[0053] Furthermore, in this embodiment, the distance between the two width-limiting baffles 400 gradually decreases in the direction close to the pressure roller 200. That is, in the transmission direction of the conveyor belt, the guide channel 410 is gradually contracted, and the width of the object to be detected can be gradually reduced, and the object to be detected will not fly or affect the transmission of the conveyor belt due to the sharp reduction in width. Of course, in other embodiments, it is also possible that in the transmission direction, the distance between the two limit baffles first gradually decreases and then remains unchanged.

[0054] In one embodiment, if Figure 2 and Figure 3As shown, the rough shaping member includes a height-limiting scraper 500, and the height difference between the height-limiting scraper 500 and the conveyor belt is greater than the height difference between the rolling surface 210 and the conveyor belt. It can be understood that the height-limiting scraper 500 needs to be set higher than the rolling surface 210 so that the height of the object to be detected reaching the pressing roller 200 is higher than the height of the rolling surface 210, and then the pressing roller 200 can play a flattening role. However, the installation position of the height-limiting scraper 500 cannot be too high, and it should be ensured that the excess height of the object to be detected reaching the pressing roller 200 compared to the rolling surface 210 does not exceed the bearing capacity of the pressing roller 200. Otherwise, the flattening effect of the pressing roller 200 will be affected. In this embodiment, the height of the object to be detected is preliminarily shaped by the height-limiting scraper 500, so that the height of the object to be detected is suitable for rolling by the pressing roller 200, thereby ensuring the flatness of the object to be detected after rolling. In addition, when the height-limiting scraper 500 and the width-limiting baffle 400 are used in combination, the height-limiting scraper 500 should be installed close to the outlet of the guiding channel 410 to prevent the object to be detected from bulging too much due to the gradual narrowing of the guiding channel 410, which affects the conveyance of the object to be detected. Moreover, the width of the height-limiting scraper 500 can be adapted to the width of the guiding channel 410, so that the object to be detected after preliminary shaping maintains a relatively flat height.

[0055] Further, in this embodiment, the height-limiting scraper 500 is liftably installed on the frame 100. In this way, the height of the object to be detected can be adjusted by driving the height-limiting baffle to move up and down relative to the frame 100. For example, when the conveyor belt conveys objects to be detected with different particle sizes, the amount by which the objects to be detected can be compressed is different, and the height of the height-limiting scraper 500 can be adaptively adjusted to ensure the flattening effect of the pressing roller 200.

[0056] In other embodiments, the rough shaping member includes a diversion scraper and a shaping scraper distributed along the upstream and downstream. The cross-sections of both are in the shape of "冂", and either of them can separately limit the width and height of the object to be detected. Among them, in the conveying direction of the conveyor belt, the width of the diversion scraper is evenly distributed, the shaping scraper is in a gradually shrinking shape with the width gradually decreasing, the width of the diversion scraper is greater than or equal to the width at the inlet of the shaping scraper, and the height of the diversion scraper is greater than the height at the inlet of the shaping scraper. To prevent the object to be detected from accumulating at the junction of the two, a baffle is provided on the upper side of the shaping scraper, which inclines towards the diversion scraper and extends upward. The width at the outlet of the shaping scraper is smaller than the distance between the two limiting surfaces of the pressing roller, and the height is greater than the height of the rolling surface. The rough shaping member arranged in this way can also preliminarily shape the object to be detected so that the object to be detected is suitable for rolling by the pressing roller.

[0057] Furthermore, in this embodiment, the height-limiting scraper 500 extends in the height direction of the frame 100, and is provided with a material stopper 510 at the upper end thereof, which is convexly disposed away from the pressing roller 200. When the height-limiting scraper 500 scrapes off the object to be detected, the object to be detected will be blocked by the material stopper 510 and will not fall to the downstream side, but will fall to the upstream side (i.e., the direction of the incoming material), so that the preliminary shaping effect on the object to be detected can be ensured.

[0058] In one embodiment, if Figures 1 to 4 As shown, the shaping mechanism further includes a cleaning member 600, which is fixedly mounted on the frame 100 and arranged corresponding to the rolling surface 210, and is used to clean the object to be detected on the rolling surface 210. In this way, when the object to be detected is stained on the rolling surface 210, the cleaning member 600 can be used to clean the object to be detected, and the surface of the rolling surface 210 is kept flat, thereby ensuring the flatness of the object to be detected after rolling.

[0059] Furthermore, the cleaning member 600 is disposed near the upstream side of the rolling surface 210. In this way, the objects to be detected stained on the rolling surface 210 will fall upstream of the roller 200 after being cleaned, and will be rolled again by the rolling surface 210 without affecting the flatness of the objects to be detected that have been shaped downstream of the roller 200. Of course, in other embodiments, the cleaning member 600 may also be provided with a collection device to collect the objects to be detected cleaned by the cleaning member 600, so that the cleaning member 600 may also be disposed near the downstream side of the rolling surface 210.

[0060] Optionally, the cleaning piece 600 may abut against the rolling surface 210 or may be at a certain distance from the rolling surface 210 to ensure that the cleaning piece 600 can clean away large particles of the object to be detected that may affect the flatness after shaping.

[0061] Optionally, the cleaning member 600 may be as wide as the rolling surface 210 to ensure the cleaning effect of the cleaning member 600 on the object to be inspected.

[0062] Optionally, the cleaning member 600 may be a brush, a sponge or a felt, among which a brush has a better cleaning effect and has less resistance to the pressure roller 200 .

[0063] The present invention also proposes a feeding system, which includes the aforementioned shaping mechanism. The specific structure of the shaping mechanism refers to the above-mentioned embodiment. This feeding system adopts all the technical solutions of all the above-mentioned embodiments, and therefore has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0064] Specifically, Figure 1As shown, the feeding system includes a frame 100, a hopper 700, a conveyor belt and a shaping mechanism. The hopper 700 is installed on the frame 100 for feeding the object to be detected. The conveyor belt is located below the hopper 700 for transporting the object to be detected. The shaping mechanism is installed on the frame 100 and is located downstream of the hopper 700. The object to be detected is fed from the hopper 700 and then unloaded onto the conveyor belt. The conveyor belt transports the object to be detected downstream. The object to be detected first passes through the shaping mechanism and is shaped into a certain shape for detection by the detector, thereby ensuring the accuracy of the detection result.

[0065] Furthermore, the hopper 700 is provided with a lower cover (not shown), which can be opened and closed to cover the discharge port of the hopper 700. In this way, when loading materials at the beginning, the lower cover can be closed first, so that the objects to be detected are accumulated in the hopper 700. When a certain amount of the objects to be detected are accumulated, the lower cover is opened to discharge the materials. With the uniform movement of the conveyor belt, the uniform discharge amount can be ensured, so that the objects to be detected are evenly distributed on the conveyor belt.

[0066] Furthermore, if Figure 1 As shown, a vibration motor 800 is installed on the outside of the hopper 700. In this way, by turning on the vibration motor 800, the wall of the hopper 700 is driven to vibrate, so as to promote the object to be detected to fall downward in the hopper 700, and avoid the object to be detected from being stuck in the hopper 700, which affects the loading of the object to be detected on the conveyor belt. Specifically, the hopper 700 can be set as a three-section structure, which is a large-diameter section, a tapered section and a small-diameter section from top to bottom. The width of the small-diameter section is adapted to the width at the entrance of the guide channel 410. The large-diameter section is convenient for feeding the object to be detected in the hopper 700, and the tapered section is to gradually guide the object to be detected from the large-diameter section to the small-diameter section. Among them, in order to ensure the falling efficiency of the object to be detected, the vibration motor 800 can be installed on the outside of the tapered section.

[0067] Furthermore, if Figure 1 As shown, the frame is a box-type structure, and the conveyor belt is accommodated in the frame. In this way, the frame can shield the conveyor belt, and the objects to be detected on the conveyor belt are not easily disturbed by the outside world. The airflow can be blocked to avoid dust. When the hopper 700 is unloading, the objects to be detected can be prevented from flying outward due to the shielding of the frame.

[0068] The present invention also proposes an online detection system, which includes the aforementioned feeding system. The online detection system also adopts all the technical solutions of all the above-mentioned embodiments, and therefore has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0069] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
