[0060] Reference is made below to Figures 1 - 15 describe the analyzer 100 according to an embodiment of the present invention.

[0061] The analyzer 100 according to an embodiment of the present invention, as Figure 1 and Figure 2 shown, the analyzer 100 includes: a feeding unit 1, a receiving unit 2, a transmission unit 3, and an identification unit 4. The transmission unit 3 includes: a support frame 31, a driving shaft 32, a driven shaft 33, a transmission belt 34, and a driving member 35. The driving shaft 32 and the driven shaft 33 are arranged on the support frame 31 at intervals along the conveying direction X of the transmission unit 3. The transmission belt 34 is fitted on the driving shaft 32 and the driven shaft 33. A part of the transmission belt 34 is located below the feeding unit 1 to receive the material 200, and another part of the transmission belt 34 extends to the receiving unit 2 to send out the material 200. At least a part of the upper surface of the transmission belt 34 constitutes a conveying channel 3a for containing the material 200. The identification unit 4 is arranged on the material conveying route from the feeding unit 1 to the receiving unit 2.

[0062] The material 200 enters from the feeding unit 1, the transmission unit 3 drives the material 200, after being identified by the identification unit 4, the material 200 is sent to the receiving unit 2 and sent out from the analyzer 100.

[0063] In the related art, analyzers are basically used for analyzing imperfect grains of grains such as rice to evaluate and improve the processing and sorting quality of the front-end equipment of the production line. Most of these analyzers use channels to convey materials and identify them one by one, with low identification and analysis efficiency and many restrictions on the material form.

[0064] The analyzer 100 according to the embodiment of the present invention adopts a transmission unit 3 with a transmission belt 34 to convey the material 200 through the transmission belt 34, so that the analyzer 100 can be used to analyze more types of materials 200, and the analyzer 100 can be applied to a wider range of fields.

[0065] The transmission unit 3 includes a support frame 31. The driving shaft 32, the driven shaft 33 and the driving member 35 are all installed on the support frame 31. The driving shaft 32 and the driven shaft 33 are rotatably arranged on the support frame 31, and the transmission belt 34 is engaged with the driving shaft 32 and the driven shaft 33. The driving member 35 is connected to the driving shaft 32, and the driving member 35 drives the driving shaft 32 to rotate actively. The transmission belt 34 engaged with the driving shaft 32 and the driven shaft 33 moves under the action of friction, and also drives the driven shaft 33 to rotate passively, so that the transmission belt 34 moves smoothly.

[0066] At least part of the transmission belt 34 is located below the feeding unit 1, and the material 200 can fall onto the transmission belt 34 from the feeding unit 1 under the action of gravity. At least part of the transmission belt 34 extends to the receiving unit 2 to convey the material 200 to the receiving unit 2. The part of the transmission belt 34 from receiving the material 200 to conveying the material 200 constitutes a conveying channel 3a, that is, a part of the upper surface of the transmission belt 34 constitutes a conveying channel 3a for containing the material 200.

[0067] The identification unit 4 is arranged on the material conveying route from the feeding unit 1 to the receiving unit 2. The material conveying route refers to the complete movement route of the material 200 from the feeding unit 1 to the receiving unit 2, including the movement route of the material 200 on the transmission belt 34 and the movement route of the material 200 in the air under the action of gravity. Thus, the identification unit 4 can detect the material 200 falling onto the transmission belt 34 and can also detect the material 200 located in the air, and can detect the material 200 without dead angles of 360 degrees to realize the quality of the material 200 such as shape and size, or the content of impurities, so as to meet various detection requirements, so that the analyzer 100 can be used to analyze more types of materials 200, and the analyzer 100 can be applied to a wider range of fields.

[0068] According to the analyzer 100 of the embodiments of the present invention, by adopting the transmission unit 3 with the conveyor belt 34, the material 200 is conveyed by the conveyor belt 34. The conveyor belt 34 can not only carry grains such as rice, but also carry various materials 200 such as nuts, fruits and vegetables, Chinese herbal medicines, plastic sheets, etc.; and the setting of the recognition unit 4 can detect the material 200 from multiple angles, which can meet the detection requirements of various materials 200, so that the analyzer 100 can be used to analyze more types of materials 200, and the analyzer 100 can be applied to a wider range of fields.

[0069] In some embodiments of the present invention, as Figure 2 shown, the transmission unit 3 further includes: a baffle 36, the baffle 36 is arranged along the conveying direction X of the transmission unit 3, and the baffle 36 is located above the upper surface of the conveyor belt 34; the baffle 36 is arranged in pairs, and the two baffles 36 in the same pair are arranged at intervals along the width direction of the conveyor belt 34, and the part of the upper surface of the conveyor belt 34 between the two baffles 36 in the same pair constitutes a conveying channel 3a.

[0070] The baffle 36 extends along the conveying direction X of the transmission unit 3, and the paired baffles 36 are arranged at intervals along the direction perpendicular to the transmission direction of the transmission unit 3 and are arranged at intervals along the width direction of the conveyor belt 34. The part of the upper surface of the conveyor belt 34 defined between the baffles 36 constitutes a conveying channel 3a. By setting the baffle 36, the conveying path range of the material 200 can be limited, the situation that the material 200 escapes from the conveyor belt 34 during the transmission process can be improved, and the working reliability of the transmission unit 3 can be enhanced.

[0071] For materials 200 of different sizes, the same or different baffles 36 can be selected to define different ranges of conveying channels 3a to meet the conveying requirements of various materials 200, so that the analyzer 100 can be used to analyze more types of materials 200, and the analyzer 100 can be applied to a wider range of fields.

[0072] It should be noted that the baffle 36 can be a pair, that is, two baffles 36 are arranged along the width direction of the conveyor belt 34; or, the baffle 36 can also be multiple pairs. Optionally, multiple pairs of baffles 36 can be arranged in sequence along the transmission direction of the transmission unit 3, so that multiple pairs of baffles 36 jointly define an entire conveying channel 3a; alternatively, multiple pairs of baffles 36 are arranged at intervals along the width direction of the conveyor belt 34, so that multiple pairs of baffles 36 can define multiple parallel conveying channels 3a.

[0073] In some embodiments of the present invention, as Figure 2 shown, the baffle 36 is inclined relative to the upper surface of the conveyor belt 34.

[0074] In some embodiments of the present invention, as Figure 2As shown, the transmission unit 3 further includes: a first support rod 37 , one end of which is detachably connected to the support frame 31 , and a baffle 36 is installed on the other end of the first support rod 37 .

[0075] The first support rod 37 supports the baffle 36 , which can improve the arrangement stability and structural reliability of the baffle 36 , improve the displacement or damage of the baffle 36 under the impact of the material 200 , and improve the working stability of the baffle 36 .

[0076] In some embodiments of the present invention, Figure 2 As shown, each baffle 36 is correspondingly provided with a plurality of first support rods 37 , and the first support rods 37 are arranged at intervals along the transmission direction X of the transmission unit 3 , thereby improving the structural stability of the baffle 36 at multiple locations along the length direction.

[0077] In some embodiments of the present invention, one end of the first support rod 37 is screwed and fixed to the support frame 31, and the other end of the first support rod 37 is screwed and fixed to the baffle 36, which not only improves the connection stability but also facilitates disassembly and assembly.

[0078] In some embodiments of the present invention, Figures 2 - 4 As shown, the support frame 31 includes: a support plate 311 , which is arranged along the transmission direction X of the transmission unit 3 , and the transmission belt 34 is an annular belt, and the upper half of the transmission belt 34 is located above the support plate 311 .

[0079] The pallet 311 is extended along the transmission direction X of the transmission unit 3. The transmission belt 34 is an annular belt. The movement of the transmission belt 34 is along the ring. The pallet 311 supports the upper half of the transmission belt 34. The transmission belt 34 is supported by the pallet 311 when moving, so that the material 200 can be transported on the upper surface of the transmission belt 34 with stability.

[0080] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 As shown, the support plate 311 includes: a straight plate section 3111 and two curved sections 3112 . The two curved sections 3112 are connected to both ends of the straight plate section 3111 . Each curved section 3112 is bent downward at a section away from the straight plate section 3111 .

[0081] The upper part of the transmission belt 34 is supported by the supporting plate 311 , and the rotating part of the transmission belt 34 is supported by the curved section 3112 to generate a bend, which can improve the movement stability of the transmission belt 34 .

[0082] In some embodiments of the present invention, the curved section 3112 is configured as an arc, which can reduce the friction between the support plate 311 and the transmission belt 34 and improve the movement smoothness of the transmission belt 34 .

[0083] In some embodiments of the present invention, the pallet 311 is configured as a stainless-steel part, which can improve the wear resistance of the pallet 311, reduce the friction between the pallet 311 and the conveyor belt 34, improve the smooth movement of the conveyor belt 34, and stably convey the material 200. Burrs are removed before bending the pallet 311 to form the bent section 3112, and the bent section 3112 and the straight section 3111 are polished to further reduce frictional damage and have good sound insulation effect.

[0084] In some embodiments of the present invention, as Figure 2 and Figure 3 shown, the support frame 31 includes: two support rods 312 spaced apart along the width direction of the conveyor belt 34, each support rod 312 being arranged along the conveying direction X of the conveying unit 3; a connecting rod 313, the connecting rod 313 being connected between the two support rods 312; a pair of mounting shafts 314, the mounting shafts 314 being mounted on the two support rods 312; both ends of the driving shaft 32 and both ends of the driven shaft 33 are mounted on the mounting shafts 314 through bearings 3141.

[0085] The support frame 31 includes the support rods 312 on both sides and the connecting rod 313 connecting the support rods 312 on both sides. The mounting shaft 314 extends along the width direction of the conveyor belt 34, and the mounting shaft 314 is fixedly connected to the two support rods 312. A mounting shaft 314 is provided corresponding to the driving shaft 32, and a mounting shaft 314 is provided corresponding to the driven shaft 33. The mounting shafts 314 are directly fixed on the support rods 312, thereby defining the positions of the driving shaft 32 and the driven shaft 33 that cooperate with the mounting shaft 314 and improving the structural accuracy.

[0086] Both ends of the driving shaft 32 are mounted on the corresponding mounting shafts 314 through bearings 3141, and both ends of the driven shaft 33 are mounted on the corresponding mounting shafts 314 through bearings 3141, so that the driving shaft 32 and the driven shaft 33 can rotate relative to the support rods 312.

[0087] In some embodiments of the present invention, the driving shaft 32 and the driven shaft 33 are connected to the mounting shaft 314 through built-in bearings. The built-in bearings save space, have high coaxiality and good service life.

[0088] In some embodiments of the present invention, the support frame 31 includes: a pallet 311, the pallet 311 being arranged along the conveying direction X of the conveying unit 3, the pallet 311 being arranged on the connecting rod 313, the connecting rod 313 playing a supporting role for the pallet 311, the conveyor belt 34 being an endless belt, and the upper half of the conveyor belt 34 being located above the pallet 311. Under the combined action of the support rods 312, the connecting rod 313 and the pallet 311, the conveyor belt 34 is stably supported and moves stably along the loop.

[0089] In some embodiments of the present invention, as Figure 2 and Figure 3As shown, an installation groove 3123 is provided on the support rod 312. The opening 31231 of the installation groove is arranged upward, and the installation shaft 314 is assembled in the installation groove 3123 through the opening 31231. The transmission unit 3 further includes: a pressing block 38, which is detachably installed on the support frame 31 and seals the opening.

[0090] It should be noted that the opening 31231 of the installation groove is arranged upward. The opening 31231 of the installation groove can be opened vertically upward, or can be inclined upward at a certain angle to the vertical direction.

[0091] The installation shaft 314 is assembled in the installation groove 3123 through the opening, and the installation shaft 314 can only leave the groove in the direction of the opening 31231 of the installation groove. The direction of the opening 31231 of the installation groove, that is, the direction from the opening to the bottom of the installation groove 3123 on the installation groove 3123 is the installation direction Y of the installation groove. The opening 31231 of the installation groove is arranged upward, while the pulling force of the transmission belt 34 is along the horizontal direction. Therefore, the opening of the installation groove 3123 can improve the layout stability of the installation shaft 314 and reduce the occurrence of the installation shaft 314 disengaging from the installation groove 3123.

[0092] The installation shaft 314 is assembled in the installation groove 3123 through the opening, and the installation shaft 314 is locked in the installation groove 3123 by the pressing block 38, which can improve the installation stability between the installation shaft 314 and the support rod 312. Exemplarily, the pressing block 38 is detachably installed on the support rods 312 on both sides by bolts, which is convenient for disassembly, installation and cleaning.

[0093] In some embodiments of the present invention, as Figure 2 shown, the support rod 312 is configured as a square tube, and the installation groove 3123 is opened on the square tube, which can reduce the crosstalk of the installation shaft 314 relative to the support rod 312.

[0094] In some embodiments of the present invention, as Figure 4 shown, the direction from the opening to the bottom of the installation groove 3123 on the installation groove 3123 is the installation direction Y of the installation groove; on at least one installation groove 3123, the included angle a between its installation direction Y and the transmission direction X of the transmission unit 3 is an acute angle, and the direction from the opening to the bottom of the groove is consistent with the tension direction of the transmission belt 34.

[0095] After the installation shaft 314 is installed in the installation groove 3123, the pulling force of the transmission belt 34 is along the horizontal direction. Since the included angle a between the installation direction Y of the installation groove and the transmission direction X of the transmission unit 3 is an acute angle, the installation shaft 314 receives an obliquely inward pressure after being inserted into the installation groove 3123, thereby preventing the installation shaft 314 from disengaging from the installation groove 3123.

[0096] In some embodiments of the present invention, as Figure 2As shown, the support rod 312 includes: a main rod 3121 and an extension rod 3122. The extension rod 3122 is adjustably mounted on the main rod 3121 along the extension direction of the main rod 3121. One of the driving shaft 32 and the driven shaft 33 is mounted on the main rod 3121, and the other is mounted on the extension rod 3122.

[0097] By providing the extension rod 3122, the size of the support rod 312 can be increased, and then the size of the transmission belt 34 in the conveying direction X of the transmission unit 3 can be adjusted to meet the conveying requirements of various materials 200, so that the analyzer 100 can be used to analyze more types of materials 200, and the analyzer 100 can be applied to a wider range of fields.

[0098] In some embodiments of the present invention, as Figure 2 shown, a pulley 351 is provided on the driving shaft 32 inside the support rods 312 on both sides. The pulley 351 is connected to the driving member 35 through a transmission structure such as a belt, and the driving member 35 thus drives the driving shaft 32 to rotate, facilitating the disassembly and assembly of the driving shaft 32 and the frame 5.

[0102] The analyzer 100 according to the embodiments of the present invention can not only select the type of the identification unit 4 according to the analysis needs, but also select the arrangement position of the identification unit 4 according to the needs.

[0103] In some embodiments of the present invention, as Figure 1 and Figure 11 shown, the identification unit 4 includes a first identification component 41. The first identification component 41 is provided above the conveying channel 3a to identify the material 200 by means of the background provided by the transmission belt 34.

[0104] Optionally, the first identification component 41 can be one or more of an ultraviolet identification component, an infrared identification component, and a hyperspectral identification component.

[0105] In some embodiments of the present invention, as Figure 1 、 Figure 11 and Figure 12As shown, the recognition unit 4 includes a second recognition component 42. The second recognition component 42 is correspondingly arranged along the throwing path S from the transmission unit 3 to the material receiving unit 2. At the position where the material is thrown by the conveyor belt 34, a visible light can be set to perform multi-angle full-coverage detection and recognition of the material 200.

[0106] Optionally, the second recognition component 42 can be one or more of a visible light recognition component and a transmission recognition component.

[0107] In some embodiments of the present invention, the analyzer 100 detects a large amount of information and requires a large number of detection stations. Then, the detection stations can be further increased by increasing the travel path of the material 200.

[0108] Exemplarily, for example, a channel or a conveyor belt 34 is arranged at the position of the discharge port below the material receiving unit 2 to enable the material 200 to continue to travel along the specified path, and other recognition units 4 are further added on multiple paths as needed; or, for another example, two conveyor belts 34 are used, and the visible light recognition component for recognizing the thrown object is arranged at the end of the first and / or the second conveyor belt 34. Thus, different material 200 conveying methods can be constructed through the repeated combination of multiple components such as the conveyor belt 34, the channel, and the material receiving unit 2, and multiple different detection positions can be set as needed.

[0109] In some specific embodiments of the present invention, when the analyzer 100 is used for plastic detection and needs to detect aging films, materials, light transmittance, colors, etc., a UV detection component and an infrared (hyperspectral) monitoring component can be arranged above the transmission channel 3a of the conveyor belt 34 to detect the aging film and the material respectively; a visible light detection is arranged at the throwing position of the conveyor belt 34 and a background roller is set to detect the light transmittance of the material, and then a visible light detection component is added to detect information such as the color of the material 200 thrown in the air, thereby completing the recognition and analysis of the material quality data.

[0110] As Figure 11 shown, two single-view optical path layouts can be arranged, which can be compatible with visible, infrared, and ultraviolet. In plastic sorting, ultraviolet and infrared are arranged for material sorting. In plastic sorting, multiple viewpoints can be arranged to detect color and transparency respectively.

[0111] Three viewing mirrors can be arranged in the upper and lower sorting boxes respectively. The front and rear positions, left and right positions, and angles are all different, and the material 200 can be detected without dead angles. The material 200 lamp is fixed with countersunk head screws to improve the positioning accuracy.

[0112] In some specific embodiments of the present invention, when the analyzer 100 is used for detecting nuts, Chinese herbal medicines, fruits and vegetables, etc., the conveyor belt 34 can be set only for material 200 transmission, and no recognition unit 4 is arranged above the transmission channel 3a, and then a visible light detection component is arranged at the throwing position of the material 200.

[0113] It should be noted that two cameras can be respectively arranged on the upper and lower sides of the position where the material 200 passes through the visible light detection component, and the two cameras are staggered in the horizontal direction, so as to complete the 360-degree panoramic detection of the surface of the material 200.

[0114] In some embodiments of the present invention, as Figure 5 shown, the recognition unit 4 further includes: a light-shielding plate 43 arranged on at least one side of the throwing route S, and a light-passing hole 431 is provided on the light-shielding plate 43, and the light-passing hole 431 is used for passing the light path required by the second recognition component 42.

[0115] By setting the light-shielding plate 43 and arranging the light-passing hole 431 on the light-shielding plate 43 to control the passing path of light in space, one light-shielding plate 43 can process multiple light paths, saving space and being convenient for installation; and multiple passing holes can be arranged on the light-shielding plate 43, and the opening size can be made arbitrarily, so as to adapt to different application scenarios.

[0116] In some embodiments of the present invention, as Figure 6 and Figure 7 shown, the analyzer 100 further includes: a frame 5, the frame 5 is the main body of the analyzer 100, and the feeding unit 1, the receiving unit 2, the transmission unit 3, and the recognition unit 4 are all integrally installed on the frame 5.

[0117] In some embodiments of the present invention, as Figures 6 - 8 shown, the analyzer 100 further includes other components installed on the frame 5 to enhance the functionality of the analyzer 100.

[0118] Optionally, a printer 51 is installed on the frame 5, and the test results can be printed.

[0119] Optionally, an electric dust cleaning device 52 is installed on the frame 5 to adapt to the condition of no air source.

[0120] In some embodiments of the present invention, as Figure 6 and Figure 7 shown, the analyzer 100 further includes at least one of a viewing window 6 and a display 7, the display 7 is electrically connected to the recognition unit 4, and the viewing window 6 and the display 7 are installed on the frame 5.

[0121] By setting the viewing window 6, the inside of the analyzer 100 can be directly observed, which is convenient for discovering damage inside the analyzer 100 or timely discovering working mistakes of the analyzer 100; by setting the display 7, the recognition results of the analyzer 100 can be intuitively displayed.

[0122] In some embodiments of the present invention, as Figure 1 and Figure 11As shown, the feeding unit 1 includes: a feeding hopper 11 and at least one stage of vibrating feeder 12. The vibrating feeder 12 is arranged between the feeding hopper 11 and the conveyor belt 34.

[0123] The material 200 is fed into the feeding hopper 11, and the vibrating feeder 12 sends the material 200 onto the conveyor belt 34. By arranging the vibrating feeder 12, the material 200 can fall onto the conveyor belt 34 more evenly, which is more conducive to identification.

[0124] In some embodiments of the present invention, as Figure 1 shown, the feeding unit 1 includes a feeding hopper 11 and a vibrating feeder 12. By arranging the vibrating feeder 12, the material 200 can fall onto the belt more evenly, which is more conducive to identification.

[0125] In other embodiments of the present invention, the feeding unit 1 includes two feeding hoppers 11 and two vibrating feeders 12. The feeding hoppers 11 and the vibrating feeders 12 are arranged in one-to-one correspondence. After the material 200 enters one feeding hopper 11, it falls onto the first-stage vibrating feeder 12. Then, after the material 200 enters the next hopper, it falls onto the second-stage vibrating feeder 12 and finally onto the conveyor belt 34. Arranging two stages of vibrating feeders 12 can make the material 200 fall onto the belt more evenly, which is more conducive to identification.

[0126] In some embodiments of the present invention, the feeding hopper 11 has a structure that is wider at the top and narrower at the bottom, saving space; the feeding hopper 11 has a weighing function and can determine the total weight of the test material 200.

[0127] In some embodiments of the present invention, as Figure 1 and Figure 12 shown, the feeding unit 1 further includes: an acceleration guide plate 13. One end of the acceleration guide plate 13 is arranged corresponding to the outlet of the vibrating feeder 12, and the other end extends above the conveyor belt 34. The acceleration guide plate 13 is an arc-shaped plate to guide the material 200.

[0128] By arranging the acceleration guide plate 13, the material 200 can be quickly accelerated over a short distance, matching the speed of the conveyor belt 34 and reaching relative rest as soon as possible, improving the conveying reliability of the material 200.

[0129] In some specific embodiments of the present invention, the speed of the conveyor belt 34 can reach 1.5 m / s.

[0130] In some embodiments of the present invention, as Figure 1 and Figure 9 shown, the analyzer 100 further includes at least one of a metal detection device 9 and a rejection device 8. The metal detection device 9 and the rejection device 8 are arranged at the receiving unit 2.

[0131] By setting up the metal detection device 9, the metal content in the material 200 can be detected, or whether metal impurities are doped in the material 200 can be detected; by setting up the rejection device 8, the impurities can be removed before the receiving unit 2.

[0132] In some embodiments of the present invention, as Figure 10 shown, the rejection device 8 includes an air rejection device 81. The structure of the air rejection device 81 is simple and compact, and the control is simple, which is suitable for rapid layout in a small space.

[0133] The air rejection device 81 is provided with a nozzle 811. The on-off of the gas is controlled by an electromagnetic valve to supply gas to the nozzle 811. The nozzle 811 forms a fan-shaped jet area to block the advancement of the material 200 to achieve a classification effect. Compared with a spray valve, the control is simple and the volume is smaller. Compared with a flap, the structure is simple and less is carried out.

[0134] In some embodiments of the present invention, as Figures 13 - 15 shown, the recognition unit 4 includes: an infrared light source device 46 and an ultraviolet lamp device 47. An air return port 53 is formed on the frame 5. The infrared light source device 46 and the ultraviolet lamp device 47 are respectively provided with an infrared heat dissipation fan 461 and an ultraviolet heat dissipation device 471 to accelerate heat dissipation. The arrowed lines in the figure represent the air flow direction to improve the working stability of the recognition unit 4.

[0135] The structure and working process of the material distributor according to two specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0136] Embodiment 1, the analyzer 100 is used for plastic detection. The feeding unit 1 includes two feeding hoppers 11 and two vibrating feeders 12. Arranging two-stage vibrating feeders 12 can make the material 200 fall on the belt more evenly, which is more conducive to recognition. An acceleration guide plate 13 is arranged below the secondary vibrating feeder 12, so that the material 200 can be quickly accelerated in a short distance to match the speed of the conveyor belt 34. The conveyor belt 34 is selected to be high-speed and small-sized. The speed of the conveyor belt 34 can reach 1.5 m / s. The diameter of the driving shaft 32 of the conveyor belt 34 is 30 mm. The conveyor belt 34 is selected as a black belt, which is conducive to composite spectrum recognition.

[0137] Plastics need to be detected for aging sheets, materials, light transmittance, color, etc. An ultraviolet detection component is arranged above the conveying channel 3a of the conveyor belt 34 to detect the aging sheet respectively, and an infrared recognition component or a hyperspectral recognition component is arranged to detect the material 200 of the material.

[0138] A visible light recognition component is set at the throwing position of the conveyor belt 34, and a background roller and a light source 44 are set to detect information such as the color of the material 200 thrown into the air. The background roller is white, which is conducive to recognition. The roller is as close as possible to the material 200 and close to the transmission to reduce shadows. The light source 44 is close to the optical axis of the camera, and the included angle between the light source 44 and the visible light recognition component is as small as possible to reduce shadows. A transmission recognition component is set at the throwing position of the conveyor belt 34, and a background light source 45 is set in cooperation to detect the light transmittance of the material.

[0139] A light-shielding plate 43 is also set at the throwing position of the conveyor belt 34 to block stray light. The visible light recognition component, the light source 44 and the background light source 45 are set on the upper side of the throwing position of the conveyor belt 34, and the transmission recognition component is set on the lower side of the throwing position of the conveyor belt 34 and is directly opposite to the background light source 45. There are two light-shielding plates 43, which are respectively arranged on the upper and lower sides of the throwing position of the conveyor belt 34. The light-shielding plate 43 located on the upper side separates the visible light recognition component, the light source 44 and the background light source 45 from the throwing position of the conveyor belt 34; the light-shielding plate 43 located on the lower side is arranged between the throwing position of the conveyor belt 34 and the transmission recognition component.

[0140] The light passing holes 431 on the light-shielding plate 43 located on the upper side include an irradiation grating through which the light of the light source 44 can pass, and a background grating through which the light of the background light source 45 can pass; the light passing holes 431 on the light-shielding plate 43 located on the lower side include a background grating through which the light of the background light source 45 can pass.

[0141] The irradiation light emitted by the light source 44 irradiates the throwing position of the conveyor belt 34 through the irradiation grating, and after being reflected by the material 200, it irradiates the visible light recognition component through the irradiation grating. The visible light recognition component collects clear image information of the material 200. The irradiation grating can control the passing path of light in space. It can not only make the irradiation light stably irradiate the visible light recognition component, but also block interfering stray light, process the optical path, reduce other stray light other than the irradiation light from entering the visible light recognition component, and improve the accuracy of the image information collected by the visible light recognition component. In this way, only one light-shielding plate 43 needs to be set to process most optical paths, saving space and facilitating installation.

[0142] The background light emitted by the background light source 45 passes through the background grating to the ejection position of the transmission belt 34, and continues to pass through the background grating on another shading plate 43 to the transmission identification component, and the transmission identification component can capture the background light. The background grating can control the path of light passing through the space, not only allowing the background light to stably irradiate the transmission identification component, but also blocking the irradiation light emitted by the light source 44 from irradiating the transmission identification component, and other stray light from irradiating the transmission identification component, processing the light path, reducing other stray light other than the background light from entering the transmission identification component, and improving the accuracy of the image information collected by the transmission identification component. In this way, only two shading plates 43 are needed to process most light paths, saving space and facilitating installation.

[0143] It is worth noting that one or more of the background grating and the illumination grating can be combined to allow different light to pass through together. One shading plate 43 can process most light paths, saving space and facilitating installation; and multiple gratings can be arranged on the shading plate 43, and the opening size can be made at will, so as to adapt to different application scenarios. It is also worth noting that the shading plate 43 also has a light absorbing effect on the light blocking area, which not only prevents light from passing through, but also prevents light from reflecting to the visible light recognition component, thereby reducing stray light.

[0144] The shading plate 43 may also be multi-layered. There may still be some stray light in the optical path system. By providing multiple shading plates 43, interference with the camera can be further eliminated, thereby further improving the accuracy of the image information collected by the camera.

[0145] Embodiment 2, as Figure 1 As shown, the analyzer 100 is used to detect nuts, Chinese herbal medicines, fruits and vegetables, etc. The transmission belt 34 is selected to be a textured belt, which can improve the stability of the material 200 transmission.

[0146] A high-definition camera is arranged above the transmission channel 3a of the transmission belt 34 to select the shape and color of the material 200; an infrared recognition component or a high-spectrum recognition component is arranged to detect the material of the material 200.

[0147] Then, a visible light detection component and a transmission recognition component are set at the throwing position of the material 200. The four-way cameras of the visible light detection component and the transmission recognition component detect one place, and there is no blind spot recognition. Multiple light sources 44 are set to make the surface brightness of the material 200 uniform, and a background light source 45 is set to facilitate recognition, and the background color can be changed according to the type of material 200.

[0148] A light shielding plate 43 is also provided at the throwing position of the transmission belt 34 to block stray light.

[0149] There are multiple visible light recognition components, transmission recognition components, light sources 44, and background light sources 45, and they are arranged on both the upper and lower sides of the throwing position of the conveyor belt 34. There are two light-shielding plates 43, which are respectively arranged on the upper and lower sides of the throwing position of the conveyor belt 34. The light-shielding plates 43 on the upper and lower sides separate the visible light recognition components, transmission recognition components, light sources 44, background light sources 45 from the throwing position of the conveyor belt 34.

[0150] The light-passing holes 431 on the light-shielding plate 43 include an irradiation grating through which the light of the light source 44 can pass, and a background grating through which the light of the background light source 45 can pass.

[0151] The irradiation light emitted by the light source 44 irradiates the throwing position of the conveyor belt 34 through the irradiation grating, and after being reflected by the material 200, it irradiates the visible light recognition component through the irradiation grating. The visible light recognition component collects clear image information of the material 200. The irradiation grating can control the passing path of light in space. It can not only make the irradiation light stably irradiate the visible light recognition component, but also block interfering stray light, process the optical path, reduce other stray light other than the irradiation light from entering the visible light recognition component, and improve the accuracy of the image information collected by the visible light recognition component. In this way, only one light-shielding plate 43 needs to be set to process most of the optical paths, saving space and facilitating installation.

[0152] The background light emitted by the background light source 45 irradiates the throwing position of the conveyor belt 34 through the background grating, and then continues to irradiate the transmission recognition component through the background grating on another light-shielding plate 43. The transmission recognition component can capture the background light. The background grating can control the passing path of light in space. It can not only make the background light stably irradiate the transmission recognition component, but also block the irradiation light emitted by the light source 44 from irradiating the transmission recognition component, as well as other stray light from irradiating the transmission recognition component, process the optical path, reduce other stray light other than the background light from entering the transmission recognition component, and improve the accuracy of the image information collected by the transmission recognition component. In this way, only two light-shielding plates 43 need to be set to process most of the optical paths, saving space and facilitating installation.
