Description

Technical Field

[0001] The present application relates to the technical field of detection equipment, and in particular to a bulk material X-ray foreign body detector. Background Art

[0002] X-ray foreign body detectors, also known as X-ray foreign body detectors, generate X-rays and use their penetrating power to detect metallic foreign matter and denser non-metallic foreign matter mixed in products. X-ray foreign body detectors can also be used in multiple processes such as product missing detection, damaged packaging detection, and weight detection.

[0003] The Chinese patent application with the publication number CN216052222U discloses a novel X-ray foreign body detection device, which includes a shell, an X-ray machine and a conveying device arranged inside the shell, and the conveying device is fixed to the inner side of the shell by a fixed platform; wherein the conveying device includes a conveying bracket and a driving device and a conveyor belt arranged on the conveying bracket. After the material to be inspected falls on the conveyor belt, it can be transported forward along the conveyor belt to the bottom of the X-ray machine, so that foreign body detection can be carried out normally.

[0004] When inspecting for foreign objects in bulk snacks or foods, due to their small size and large quantity, small particles of dust or impurities are easily mixed in during the conveying process at the front end. Once the bulk food enters the conveyor belt, dust or impurities will adhere to the belt, necessitating frequent cleaning to ensure the cleanliness of the belt and, in turn, the sanitation of the food. However, the conveyor belt setup is inconvenient to clean. The tensioning rollers securing the conveyor belt must be removed, and the belt must be removed and cleaned. After cleaning, the conveyor belt must be reinstalled and tested for smoothness. The entire cleaning process is cumbersome and complex, and needs improvement. Summary of the Invention

[0005] Based on this, the present application provides a bulk material X-ray foreign body detection machine, which can facilitate the disassembly and cleaning of the conveying mechanism to ensure cleanliness and hygiene during the transportation of bulk food.

[0006] The present application provides a bulk material X-ray foreign body detection machine that adopts the following technical solutions: A bulk material X-ray foreign body detection machine, comprising: Housing assembly; An X-ray detector is disposed inside the housing assembly; The bracket mechanism is provided with two groups, and the two groups of bracket mechanisms are jointly arranged inside the housing assembly; Among them, the bracket mechanism includes a basic frame and an inner plate. The basic frame is provided with an inner groove, and the inner plate is adapted to the inner groove in shape. The inner plate is fixedly mounted inside the inner groove, and a movable area is formed between the inner plate and the inner wall of the inner groove. The conveying mechanism includes multiple conveying racks. Two connecting columns are fixed to the sides of the conveying racks. Each connecting column is inserted into the moving area and moves freely within the moving area. Two adjacent connecting columns arranged on adjacent conveying racks are connected by hinges. Each conveying rack is equipped with a detachable material receiving box. The partition mechanism is fixedly mounted above the base frame and separates multiple conveying zones; A driving mechanism, which is used to drive each conveying rack to move forward; The reject mechanism is arranged at the rear end of the conveying mechanism; the reject mechanism includes multiple groups of reject units, and the number of reject units matches the number of conveying zones; each reject unit includes a material receiving plate rotatably arranged inside the housing assembly and a pneumatic component for driving the material receiving plate to rotate, the fixed end of the pneumatic component is hinged to the housing assembly, and the movable end of the pneumatic component is hinged to the material receiving plate; The discharging conveying device is arranged at the rear end of the conveying mechanism, and the receiving plate is normally inclined downward toward the discharging conveying device; The blanking box is arranged between the two basic frames. When the pneumatic component is activated, the receiving plate tilts downward toward the blanking box.

[0007] By adopting the above-mentioned technical solution, when the bulk material X-ray foreign body detector of the present application is in use, the bulk food enters the shell assembly and falls on the various receiving boxes of the conveying mechanism, and the conveyor frame moves forward under the drive mechanism, which can enable the bulk food to move forward along the various conveying areas; when the bulk food moves to the bottom of the X-ray detector, foreign body detection is performed, and the detection results can be fed back to the rejection mechanism for quality control. When metal foreign matter is found on a certain conveying drive, the corresponding pneumatic component is controlled to force the receiving plate to flip to a position tilted downward toward the blanking box. The bulk food on the conveying area can fall on the receiving plate and smoothly enter the blanking box, thereby smoothly collecting the bulk food containing foreign matter.

[0008] When the bulk material X-ray foreign body inspection machine is shut down, the receiving box can be removed from the conveyor rack to easily clean the surface of the receiving box. After cleaning, each receiving box can be quickly reinstalled on each conveyor rack, thereby quickly completing the entire cleaning operation and ensuring cleanliness and hygiene during subsequent bulk food transportation.

[0009] Optionally, the conveying frame is provided with two plug-in slots, and two plug-in posts are fixed at the bottom of the material receiving box, and the two plug-in posts are respectively matched and plugged into the two plug-in slots; a plurality of movable wing plates are rotatably embedded at one end of the plug-in post away from the material receiving box, and a first torsion spring is provided at the rotating connection between each movable wing plate and the plug-in post, and the first torsion spring is used to force the movable wing plate to be normally exposed on the outer peripheral surface of the plug-in post.

[0010] By adopting the above-mentioned technical solution, the plug-in post of the material receiving box is inserted into the plug-in slot of the conveying rack, and the movable wing plate can retract inward after abutting against the inner wall of the plug-in slot, thereby allowing the plug-in post to smoothly enter the plug-in slot, so as to realize the rapid installation of the material receiving box; after the material receiving box is installed on the conveying rack, the plug-in post passes through the plug-in slot, and the movable wing plate can be reset to be exposed on the outer peripheral surface of the plug-in post under the torsional force of the first torsion spring, thereby limiting the situation where the plug-in post directly disengages from the plug-in slot, thereby ensuring the smooth operation of the conveying mechanism.

[0011] Optionally, the moving area includes a straight line segment, a first arc segment, an oblique line segment, and a second arc segment connected in sequence, and an end of the second arc segment is connected to the straight line segment; The distance between the movable wing plate and the bottom of the material receiving box is greater than the thickness of the conveying frame. When the conveying frame is located in the straight section, the movable wing plate and the conveying frame are spaced apart from each other; when the conveying frame is located in the oblique section, the movable wing plate is pressed against the conveying frame under the action of gravity. At this time, the material receiving box and the conveying frame are spaced apart from each other.

[0012] By adopting the above-mentioned technical solution, each conveying rack can circulate within the moving area along the paths of the straight line segment, the first arc segment, the oblique line segment and the second arc segment; by making the distance from the movable wing plate to the bottom of the receiving box greater than the thickness of the conveying rack, when the conveying rack moves to the oblique line segment, the receiving box can move downward for a certain distance under the action of its own gravity. At this time, the receiving box forms a falling shaking effect, which is conducive to discharging large particles of foreign matter in the receiving box and improving the cleanliness of the receiving box.

[0013] Optionally, a guide portion is provided on one side of the movable wing near the receiving box, and a guide portion is provided on the inner peripheral edge of the connecting groove near the movable wing. When the receiving box moves away from the conveying rack, the guide portion can press against the guide portion and force each movable wing to retract inward.

[0014] By adopting the above technical solution, through the cooperation of the guiding part and the guide part, the operator can directly apply force to the receiving box to conveniently pull the receiving box out from the conveying rack, thereby further improving the convenience of the disassembly and assembly operation of the receiving box.

[0015] Optionally, an unlocking mechanism is provided between the two inner plates, and the unlocking mechanism includes two hollow ring sleeves connected to each other, and a sliding block is fixedly connected to the side of each hollow ring sleeve, and each inner plate is provided with a sliding slot, and the sliding block is slidably installed in the sliding slot; the sliding block is normally abutted against the top wall of the sliding slot through the magnetic suction component; the inner diameter size of the hollow ring sleeve is adapted to the outer diameter size of the plug-in column, the hollow ring sleeve is located above the oblique line segment, and the hollow ring sleeve is always arranged directly opposite to the plug-in column of a material receiving box.

[0016] By adopting the above-mentioned technical solution, when the conveying rack moves to the oblique section and faces the hollow ring sleeve, by forcing the hollow ring sleeve to move downward along the sliding groove, the two hollow ring sleeves can be correspondingly arranged on the outer peripheral sides of the two plug-in columns, and the hollow ring sleeves can be against each movable wing plate and force the movable wing plate to retract inward, further improving the convenience of the operator in disassembling and assembling the receiving box.

[0017] Optionally, one side of the material receiving box is open, and a movable baffle is rotatably installed on the open side of the material receiving box, and a second torsion spring is provided at the rotation connection between the movable baffle and the material receiving box, and the second torsion spring is used to force the movable baffle to normally block the open side of the material receiving box; A fixed rod column is fixed between the two inner plates and is located outside the first arc segment. When the conveyor frame moves to the first arc segment, the movable baffle abuts against the fixed rod column and flips toward the direction close to the rejection mechanism.

[0018] By adopting the above-mentioned technical solution, when the receiving box moves in the straight section, the movable baffle can normally press against the open side of the receiving box under the torsional force of the second torsion spring, thereby smoothly driving the bulk food to be transported forward; when the conveying rack moves to the first arc section, the receiving box is in an inclined state. At this time, the movable baffle will be blocked by the fixed rod column and flipped in the direction close to the rejection mechanism, so that the bulk food can fall smoothly onto the receiving plate along the movable baffle, reducing the occurrence of bulk food accidentally falling out of the conveying mechanism.

[0019] Optionally, the partition mechanism includes a plurality of partition plates arranged at intervals and fixed to each other, and when the material receiving box is located in a straight section, each partition plate is in contact with the material receiving box; a plurality of first notches are provided on the side of the material receiving box, and a plurality of second notches are provided on the movable baffle, and each second notch is normally arranged opposite to each first notch; when the material receiving box is located in a straight section, each partition plate is respectively correspondingly passed through the first notch and the second notch opposite to each other, and a conveying grid area for storing bulk food is formed between every two adjacent partition plates and the material receiving box.

[0020] By adopting the above-mentioned technical solution, the partition mechanism forms multiple conveying areas through the partition plate. At the same time, the setting of the top frame of the receiving box and the movable baffle can form multiple conveying grids on the surface of each receiving box. When bulk food falls into the receiving box, it can be stored in the conveying grid, and each conveying grid can be conveyed to the bottom of the X-ray detector for foreign body detection; if a metal foreign body is detected, the bulk food in the corresponding conveying grid can be dropped into the drop box through the rejection mechanism. The amount of bulk food contained in a conveying grid is relatively small, which can effectively reduce the amount of qualified bulk food that is mistakenly rejected and reduce waste.

[0021] Optionally, the driving mechanism includes a fixed plate frame, a toggle plate, a vertical guide rod and a transverse guide rod, the fixed plate frame is fixed between the two inner plates, and the transverse guide rod is fixedly mounted above the fixed plate frame; A sleeve portion is provided at the bottom end of the vertical guide rod, and the vertical guide rod is slidably sleeved on the horizontal guide rod through the sleeve portion; an extension portion is provided on the side of the toggle plate, and the extension portion is provided with a through groove for the vertical guide rod to match and pass through, and a limit piece is provided on the end of the vertical guide rod away from the sleeve portion for preventing the extension portion from being separated; The side of the extension part is connected to a power component for driving the toggle plate to circulate; a plurality of toggle blocks are provided on the top of the toggle plate, and when the toggle plate moves upward along the vertical guide rod, the toggle blocks enter the outside of the conveying rack; when the toggle plate moves forward along the horizontal guide rod, the toggle blocks can drive the conveying rack to move forward.

[0022] By adopting the above-mentioned technical solution, the present application controls the operation of the power assembly, which drives the toggle plate to gradually move upward along the vertical guide rod, allowing the toggle block to enter the outside of the conveyor rack. When the toggle plate moves upward to the limit position, as the power assembly continues to operate, the vertical guide rod can move laterally along the transverse guide rod, at which point the toggle block can push the conveyor rack forward, thereby causing each conveyor rack to move forward together by a specific distance. Then, after the vertical guide rod moves laterally to the limit position, as the power assembly continues to operate, the toggle plate gradually moves downward along the vertical guide rod, allowing the toggle block to smoothly detach from the conveyor rack. After the toggle plate moves downward to the limit position, as the power assembly continues to operate, the vertical guide rod can return along the transverse guide rod, thereby causing the toggle block to move below another conveyor rack. Based on this, intermittent movement of the conveyor rack can be achieved. When the conveyor rack moves to the oblique line segment, the bulk food in the conveyor grid has sufficient time to fall onto the receiving plate and be collected in the drop box.

[0023] Optionally, the power assembly includes a driving motor fixedly mounted on a fixed plate frame and a rotating seat fixedly connected to an output end of the driving motor, wherein the rotating seat is provided with a through movable socket; The side of the extension part is rotatably connected to a movable column, the outer diameter of the movable column is adapted to the inner diameter of the movable socket; the movable column is movably inserted into the movable socket, and a return spring is provided between the movable column and the rotating seat, and the return spring is sleeved on the movable column.

[0024] By adopting the above-mentioned technical solution, the setting of the return spring enables an elastic connection between the rotating seat and the movable column. When the driving motor is running, the rotating seat can drive the movable column to rotate circumferentially, thereby forcing the toggle plate to move cyclically along the rectangular path to realize intermittent movement of the conveying rack.

[0025] Optionally, a working window is provided on the side of the shell assembly, and the working window is opposite to the conveying mechanism; the working window is installed with a detachable sealing plate.

[0026] By adopting the above-mentioned technical solution, the sealing plate is normally installed on the working window, which can keep the interior of the shell assembly in a closed state and reduce the occurrence of radiation leakage to the outside; when the connecting box needs to be disassembled and cleaned, the connecting box can be easily disassembled and replaced by removing the sealing plate.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The connection between the plug-in column and the plug-in slot allows the material receiving box to be easily removed from the conveyor rack, and the surface of the material receiving box can be easily cleaned. After cleaning, each material receiving box can be quickly reinstalled on each conveyor rack, thereby quickly completing the entire cleaning operation and ensuring clean and hygienic transportation of subsequent bulk food. 2. By setting up an unlocking mechanism, when the conveyor frame moves to the oblique line segment and faces the hollow ring, the hollow ring is forced to move downward along the sliding groove, and the two hollow rings can enter the outer circumference of the two plug-in columns respectively. The hollow rings can also abut against each movable wing and force the movable wing to retract inward, further improving the convenience of the operator to disassemble and assemble the receiving box; 3. By setting up transverse guide rods and vertical guide rods, when the drive motor is running, the rotating seat can drive the movable column to rotate circumferentially, thereby forcing the toggle plate to move laterally along the transverse guide rods and vertically along the vertical guide rods, thereby making the toggle plate move cyclically along the rectangular path to realize intermittent movement of the conveyor rack.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1 -Attached Figure 12 This application is described in further detail.

[0031] The embodiment of the present application discloses a bulk material X-ray foreign body detection machine.

[0032] Reference Figure 1A bulk material X-ray foreign body detector includes a shell assembly 1, which includes a main shell 11 fixedly mounted on a ground foundation and a control box 12 fixed on the top of the main shell 11. A display screen 13 is installed on the side of the control box 12, and a control module for controlling the operation of each component is fixed inside the control box 12; an operation window is opened on the side of the main shell 11, and a sealing plate 14 is provided on the inside of the operation window. The sealing plate 14 is detachably fixed to the main shell 11 by fasteners and seals the operation window.

[0033] Reference Figure 2 The housing assembly 1 is internally provided with a support mechanism 2, a conveying mechanism 3, a driving mechanism 4, and a rejecting mechanism 5. There are two sets of support mechanisms 2, which are spaced apart and fixed to the inner bottom wall of the main housing 11. A work window is provided opposite the conveying mechanism 3 and the support mechanisms 2. The support mechanism 2 comprises a base frame 21 and an inner panel 22. The base frame 21 is fixed to the main housing 11, and an inner groove is formed through the side of the base frame 21. The inner panel 22 has the same shape as the inner groove and is located inside the inner groove. A plurality of connecting blocks 23 are fixed between the inner panel 22 and the base frame 21. The arrangement of the connecting blocks 23 secures the inner panel 22 to the inner groove.

[0034] Reference Figure 3 The inner plate 22 and the inner wall of the inner groove are spaced apart from each other and form a moving area 24. The moving area 24 in the present application includes a straight line segment 241, a first arc segment 242, an oblique line segment 243 and a second arc segment 244 connected in sequence. The end of the second arc segment 244 is connected to the straight line segment 241, thereby forming a circular path connected end to end. It should be noted that, in this embodiment, the straight line segment 241 will be located above the oblique line segment 243.

[0035] Reference Figure 4 The conveying mechanism 3 includes a plurality of conveying racks 31, and the two opposite sides of the conveying rack 31 in the length direction are respectively fixed with connecting posts 311, and the number of connecting posts 311 on one side is two; at the same time, refer to Figure 2 Each connecting post 311 is inserted into the movable region 24 and is able to move freely along the path of the movable region 24. Two adjacent connecting posts 311 located on adjacent conveyor racks 31 are connected by a hinge (not shown), thereby enabling the conveyor racks 31 to move together. It should be noted that the hinge connecting the two adjacent connecting posts 311 is slightly relaxed, allowing the connecting posts 311 to smoothly pass through the first arc segment 242 and the second arc segment 244.

[0036] Back to Figure 4Each conveyor rack 31 is provided with a detachable material receiving box 32. Specifically, two plug-in slots 312 are provided on the surface of the conveyor rack 31.

All movable flaps 322 are equidistantly arranged around the central axis of the plug post 321. The rotational connection between the movable flaps 322 and the plug post 321 is located at the bottom of the movable flaps 322. Each of the movable flaps 322 and the plug post 321 is provided with a first torsion spring at the rotational connection. The first torsion spring can always generate a torsional force acting on the movable flaps 322 and force the movable flaps 322 to normally be exposed on the outer circumference of the plug post 321. The provision of the movable flaps 322 can prevent the plug post 321 from retreating or disengaging from the plug slot 312 after the plug post 321 passes through the plug slot 312.

[0038] The movable wing plate 322 is provided with a guide portion 323 on one side close to the receiving box 32. Figure 6 The guide portion 313 is provided on the inner peripheral edge of the insertion groove 312 near the movable wing plate 322; when the material receiving box 32 needs to be removed, the material receiving box 32 is moved away from the conveying rack 31 by applying force to the material receiving box 32, and the guide portion 323 can contact the guide portion 313 and force each movable wing plate 322 to retract inward, thereby improving the convenience of the disassembly and assembly of the material receiving box 32.

[0039] Back to Figure 6 In this embodiment, the distance between the movable wing 322 and the bottom of the receiving box 32 is greater than the thickness of the conveying rack 31; Figure 2 When the conveyor rack 31 is located in the straight section 241, the material receiving box 32 can be located above the conveyor rack 31, and the material receiving box 32 is pressed against the conveyor rack 31 under the action of its own gravity. At this time, the movable wing plate 322 is spaced apart from the bottom surface of the conveyor rack 31; and when the conveyor rack 31 moves to the oblique section 243, the material receiving box 32 is located below the conveyor rack 31. At this time, the material receiving box 32 moves downward under the action of its own gravity, enabling the movable wing plate 322 to press against the conveyor rack 31, thereby making the material receiving box 32 and the conveyor rack 31 spaced apart.

[0044] The side of the extension portion 421 is connected to a power component for driving the toggle plate 42 to cyclically move; specifically, the power component includes a drive motor 45 and a rotating seat 46, the drive motor 45 is fixedly mounted on the fixed plate frame 41, and the rotating seat 46 is fixedly connected to the output end of the drive motor 45; the rotating seat 46 in this embodiment is located above the middle section of the transverse guide rod 44, and a through movable socket 461 is opened on one side of the rotating seat 46.

[0045] The side of the extension part 421 is rotatably connected to a movable column part 47, and the outer diameter of the movable column part 47 is adapted to the inner diameter of the movable socket 461; the movable column part 47 is movably inserted into the movable socket 461, and a return spring 48 is sleeved on the outer peripheral side of the movable column part 47, one end of the return spring 48 rests on the rotation connection between the movable column part 47 and the extension part 421, and the other end rests on the rotating seat 46; the return spring 48 can always generate an elastic force acting on the movable column part 47, thereby making the movable column part 47 always have a tendency to move away from the rotating seat 46.

[0046] Reference Figure 8 、 Figure 9 It can be understood that when the drive motor 45 is running and the output shaft of the drive motor 45 rotates circumferentially, it can drive the extension portion 421 to move upward along the vertical guide rod 43. This is the first movement path. After the extension portion 421 moves upward to the limit position, the vertical guide rod 43 can be forced to move along the transverse guide rod 44. This is the second movement path. Then, after the vertical guide rod 43 moves laterally to the limit position, the extension portion 421 can move downward along the vertical guide rod 43. This is the third movement path. After the extension portion 421 moves downward to the limit position, the vertical guide rod 43 is forced to retract along the transverse guide rod 44. This is the fourth movement path. After the first, second, third, and fourth movement paths, the extension portion 421 returns to its initial position, completing a movement cycle.

[0047] The top of the toggle plate 42 is provided with a plurality of toggle blocks 422, Figure 10In this embodiment, each group of shift blocks 422 contains two shift blocks 422. When the drive motor 45 is running and the extension 421 traverses the first movement path, adjacent shift blocks 422 can enter between the movable baffle 324 and the conveyor rack 31. Then, through the second movement path, the shift blocks 422 can drive all conveyor racks 31 forward, thereby causing each receiving box 32 to move sequentially below the X-ray detector for foreign object detection. It should be noted that during the time period when the extension 421 traverses the third and fourth movement paths, the receiving box 32 located in the first arc segment 242 can maintain its tilted state.

[0048] Back to Figure 4 The cross-section of the material receiving box 32 is concave, and one side of the material receiving box 32 is open; a movable baffle 324 is rotatably installed on the open side of the material receiving box 32, and a second torsion spring is provided between the movable baffle 324 and the rotating part of the material receiving box 32, and the second torsion spring can always generate a torsion force acting on the movable baffle 324, thereby forcing the movable baffle 324 to normally block the open side of the material receiving box 32, so that a storage area 325 for storing bulk food is formed between the material receiving box 32 and the movable baffle 324; here, the bottom of the movable baffle 324 has a load-bearing portion 3241 extending to the bottom of the conveying rack 31.

[0049] Also refer to Figure 1 In this embodiment, the length of the main shell 11 is greater than the length of the control box 12. The control box 12 is located in the middle position of the top of the main shell 11, so that both sides of the main shell 11 in the length direction can be exposed to the control box 12; a feed port 111 is partially opened on the top surface of the exposed part of the main shell 11, and a feed cabin 15 is fixedly mounted inside the feed port 111. The feed cabin 15 is located above the straight section 241 and is arranged opposite to a receiving box 32; bulk snacks processed in the front-end process can enter the feed cabin 15 and fall smoothly into the storage area 325.

[0050] Back to Figure 2 、 Figure 3 When the conveyor frame 31 moves from the straight segment 241 to the first arc segment 242 under the drive of the driving mechanism 4, the receiving box 32 will gradually turn over to an inclined state; it should be noted here that when the receiving box 32 is located in the first arc segment 242, the movable baffle 324 will be located on the side of the receiving box 32 away from the feed chamber 15. Figure 7 A fixed rod column 222 is fixed between the two inner plates 22, and the fixed rod column 222 is located outside the first arc segment 242; Figure 11When the receiving box 32 is located at the first arc segment 242, the load-bearing portion 3241 of the movable baffle 324 can be against the fixed rod column 222, thereby causing the movable baffle 324 to flip in the direction away from the feed chamber 15, so that the bulk snacks in the storage area 325 can fall to the next workstation along the movable baffle 324.

[0051] Back to Figure 2 A partition mechanism 7 is fixedly mounted on the top of the two basic frames 21. The partition mechanism 7 includes a plurality of partition plates 71 arranged at intervals from each other. An axial rod 72 is commonly connected and fixed between all the partition plates 71, thereby connecting and fixing each partition plate 71 to each other; a conveying area 73 is formed between adjacent partition plates 71 spaced apart from each other.

[0052] In addition, refer to Figure 4 The movable baffle 324 is provided with a plurality of second notches 3242, and the side of the receiving box 32 is provided with a plurality of first notches 326. The number of the first notches 326 and the number of the second notches 3242 are equal to the number of the partition plate 71. Each first notch 326 and each second notch 3242 are arranged opposite to each other under normal conditions. Figure 12 When the receiving box 32 moves to the straight section 241, the partition plates 71 abut against the inner surface of the receiving box 32, and each partition plate 71 can be respectively correspondingly inserted into the first notch 326 and the second notch 3242 that are opposite to each other. At this time, a conveying grid 74 for storing bulk food is formed between every two adjacent partition plates 71 and the receiving box 32.

[0053] Back to Figure 2 It should also be noted that each partition plate 71 is hinged with a hinge plate 75 on one side close to the first arc segment 242. The hinge plate 75 normally rests against the material receiving box 32 of the first arc segment 242 under the action of its own gravity, and due to the free rotation setting of the hinge plate 75, the hinge plate 75 can rotate to avoid when the material receiving box 32 moves, thereby reducing the possibility of interference between the material receiving box 32 and the partition mechanism 7.

[0054] The X-ray detector is fixed inside the control box 12, and the detection head of the X-ray detector is facing downward, directly facing one of the receiving boxes 32; the setting of the X-ray detector can detect the bulk food in each conveying grid 74 on the receiving box 32, test out the bulk food containing metal foreign matter, and then control the rejection mechanism 5 to reject the bulk food in the conveying grid 74 through signals to ensure food safety.

[0055] The rejection mechanism 5 is arranged on the outside of the second arc segment 244. The rejection mechanism 5 includes multiple groups of rejection units, and the number of rejection units is set to be equal to the number of conveying zone channels 73; wherein, the rejection unit includes a material receiving plate 51 and a pneumatic component 52, and the material receiving plate 51 is rotatably mounted on the sides of the two basic frames 21; the pneumatic component 52 in this embodiment is a cylinder, and the fixed end of the pneumatic component 52 is hinged to the inner bottom wall of the main shell 11, and the movable end of the pneumatic component 52 is hinged to the material receiving plate 51.

[0056] Also refer to Figure 1 A discharge port 112 is formed on a side of the main housing 11, away from the feed port 111. The discharge port 112 is equipped with a discharge conveyor 8, which is located at the rear end of the conveying mechanism 3. The receiving plate 51 is normally tilted downward toward the discharge conveyor 8. During normal use, the top of the receiving plate 51 is tilted toward the receiving box 32 located on the first arc segment 242, catching the bulk snacks dropped from the movable baffle 324.

[0057] In addition, a blanking box 53 is provided between the two basic frames 21, and the blanking box 53 is located below the first arc segment 242; if a certain conveying grid area 74 is detected to contain metal foreign matter by the X-ray detector, the corresponding pneumatic component 52 can be activated and force the receiving plate 51 to flip over, so that the receiving plate 51 can flip over to tilt downward toward the blanking box 53; at this time, the bulk snacks in the conveying grid area 74 containing metal foreign matter fall on the receiving plate 51 and can fall into the blanking box 53 for collection, so as to facilitate the collection and cleaning of unqualified products.
