Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection equipment, and in particular relates to a bulk X-ray foreign matter detection machine. BACKGROUND

[0002] The X-ray foreign matter detection machine, also known as an X-ray foreign matter detection machine, detects metal foreign matter mixed in products and non-metal foreign matter with high density through the generation of X-rays by the equipment and the penetration ability of X-rays. In addition, the X-ray foreign matter detection machine can also be applied to product missing detection, damaged packaging detection, and weight detection in multiple processes.

[0003] At present, a new type of X-ray foreign matter detection device is disclosed in Chinese patent CN216052222U, which comprises a shell, an X-ray machine and a conveying device are arranged in the shell, and the conveying device is fixed on the inner side of the shell through a fixing table. The conveying device comprises a conveying support, a driving device and a conveying belt arranged on the conveying support. After the material to be detected falls on the conveying belt, it can be conveyed forward to the position below the X-ray machine, so that normal foreign matter detection can be performed.

[0004] When detecting foreign matter in bulk snacks or food, small particles of dust or impurities are easily mixed in the conveying process of the front-end process due to the small volume and large number of bulk food. After the bulk food enters the conveying belt, dust or impurities will adhere to the conveying belt, and cleaning needs to be performed frequently to ensure the cleanliness of the conveying belt and thus ensure the cleanliness of the food. However, the cleaning of the conveying belt is inconvenient, and the tensioning roller for fixing the conveying belt needs to be disassembled, and the conveying belt needs to be taken out and cleaned. After cleaning, the conveying belt needs to be reinstalled and the conveying stability needs to be debugged. The whole cleaning process is complicated and needs to be improved. SUMMARY

[0005] Therefore, the present application provides a bulk X-ray foreign matter detection machine which can facilitate the disassembly and cleaning of the conveying mechanism to ensure the cleanliness of the bulk food during conveying.

[0006] The bulk X-ray foreign matter detection machine provided by the present application adopts the following technical scheme:

[0007] A bulk X-ray foreign matter detection machine comprises:

[0008] a shell assembly;

[0009] an X-ray detector arranged inside the shell assembly;

[0010] a support mechanism, the support mechanism is provided with two groups, and the two groups of support mechanisms are arranged inside the shell assembly together;

[0011] The support mechanism comprises a base frame and an inner plate, the base frame is provided with an inner groove, and the inner plate is matched with the inner groove in shape; the inner plate is fixedly arranged in the inner groove, and a moving area is formed between the inner plate and the inner wall of the inner groove;

[0012] The conveying mechanism comprises a plurality of conveying frames, two connecting columns are fixedly arranged on the side surface of each conveying frame, each connecting column is inserted into the moving area and freely moves in the moving area; two adjacent connecting columns between adjacent conveying frames are connected through a hinge; and each conveying frame is provided with a detachable receiving box.

[0013] The partition plate mechanism is fixedly arranged above the base frame, and the partition plate mechanism divides a plurality of conveying channels;

[0014] The driving mechanism is used for driving each conveying frame to move forward;

[0015] The removing mechanism is arranged at the rear end of the conveying mechanism, and the removing mechanism comprises a plurality of removing units, the number of the removing units is matched with the conveying channels; each removing unit comprises a receiving plate rotatably arranged in a shell assembly and a pneumatic component used for driving the receiving plate to rotate, the fixed end of the pneumatic component is hingedly connected to the shell assembly, and the movable end of the pneumatic component is hingedly connected to the receiving plate;

[0016] The discharging conveying device is arranged at the rear end of the conveying mechanism, and the receiving plate is normally inclined downward to the discharging conveying device;

[0017] The falling box is arranged between the two base frames, and when the pneumatic component acts, the receiving plate is inclined downward to the falling box.

[0018] When the bulk food enters the shell assembly and falls on each receiving box of the conveying mechanism, the conveying frame moves forward under the driving of the driving mechanism, so that the bulk food moves forward along each conveying channel; when the bulk food moves to the position below the X-ray detector, the foreign matter is detected, the detection result can be fed back to the removing mechanism for quality control; when metal foreign matter is found on a conveying drive, the corresponding pneumatic component is controlled to act to force the receiving plate to turn to the position inclined downward to the falling box, and the bulk food on the conveying channel can fall on the receiving plate and smoothly enter the falling box, thereby smoothly collecting the bulk food containing foreign matter.

[0019] When the bulk X-ray foreign matter detection machine is stopped, the receiving box can be easily removed from the conveying frame, the surface of the receiving box can be easily cleaned, and each cleaned receiving box can be quickly reinstalled on each conveying frame, thereby quickly completing the entire cleaning operation and ensuring the cleanliness of the subsequent bulk food conveying.

[0020] Optionally, the conveyor frame is provided with two insertion slots, and two insertion posts are fixed at the bottom of the receiving box. The two insertion posts are respectively matched and inserted into the two insertion slots. Multiple movable wing plates are rotatably embedded at the end of the insertion post away from the receiving box. Each movable wing plate is provided with a first torsion spring at the rotatable connection between it and the insertion post. The first torsion spring is used to force the movable wing plate to be normally exposed on the outer circumference of the insertion post.

[0021] By adopting the above technical solution, the insert pin of the receiving box is inserted into the insertion slot of the conveyor frame. After the movable wing plate abuts against the inner wall of the insertion slot, it can retract inward, thereby allowing the insert pin to smoothly enter the insertion slot, so as to achieve rapid installation of the receiving box. After the receiving box is installed on the conveyor frame, the insert pin passes through the insertion slot. Under the torsion of the first torsion spring, the movable wing plate can be reset to be exposed on the outer circumference of the insert pin, thereby preventing the insert pin from directly disengaging from the insertion slot, so as to ensure the smooth operation of the conveying mechanism.

[0022] Optionally, the movable area includes a straight line segment, a first arc segment, an oblique line segment, and a second arc segment connected in sequence, with the end of the second arc segment connected to the straight line segment;

[0023] The distance between the movable wing plate and the bottom of the receiving box is greater than the thickness of the conveyor frame. When the conveyor frame is on a straight section, the movable wing plate and the conveyor frame are spaced apart. When the conveyor frame is on an inclined section, the movable wing plate abuts against the conveyor frame under the action of gravity, and at this time the receiving box and the conveyor frame are spaced apart.

[0024] By adopting the above technical solution, each conveyor can circulate within the moving area along the path of the straight section, the first arc section, the oblique section, and the second arc section. By making the distance between the movable wing plate and the bottom of the receiving box greater than the thickness of the conveyor, when the conveyor moves to the oblique section, the receiving box can move downward a certain distance under its own gravity. At this time, the receiving box forms a falling and shaking effect, which is conducive to discharging large particles of foreign matter in the receiving box and improving the cleanliness of the receiving box.

[0025] Optionally, the movable wing plate is provided with a guide on the side near the receiving box, and the insertion slot is provided with a guide on the inner peripheral edge of the movable wing plate. When the receiving box moves away from the conveyor frame, the guide can abut against the guide and force each movable wing plate to retract inward.

[0026] By adopting the above technical solution, and through the cooperation of the guide and the directing parts, the operator can easily pull the receiving box out of the conveyor frame by directly applying force to the receiving box, further improving the convenience of the receiving box disassembly and assembly operation.

[0027] Optionally, an unlocking mechanism is provided between the two inner plates. The unlocking mechanism includes two hollow rings connected to each other. A sliding block is fixedly connected to the side of each hollow ring. Each inner plate has a sliding slot. The sliding block is slidably installed in the sliding slot. The sliding block is normally abutted against the top wall of the sliding slot by a magnetic component. The inner diameter of the hollow ring is adapted to the outer diameter of the plug-in post. The hollow ring is located above the inclined segment and is always directly opposite the plug-in post of a receiving box.

[0028] By adopting the above technical solution, when the conveyor frame moves to the inclined section and is directly opposite the hollow ring sleeve, the hollow ring sleeve is forced to move downward along the sliding groove. The two hollow ring sleeves can be correspondingly fitted onto the outer periphery of the two plug-in columns, and the hollow ring sleeves can abut against each movable wing plate and force the movable wing plate to retract inward, further improving the convenience of the operator to disassemble and assemble the receiving box.

[0029] Optionally, one side of the receiving box is open, and a movable baffle is rotatably installed on the open side of the receiving box. A second torsion spring is provided at the rotatable connection between the movable baffle and the receiving box. The second torsion spring is used to force the movable baffle to normally seal the open side of the receiving box.

[0030] A fixed rod is fixed between the two inner plates, and the fixed rod is located outside the first arc segment; when the conveyor moves to the first arc segment, the movable baffle abuts against the fixed rod and flips towards the rejection mechanism.

[0031] By adopting the above technical solution, when the receiving box moves in a straight section, the movable baffle can normally abut against the open side of the receiving box under the torsion of the second torsion spring, thus smoothly driving the bulk food forward; when the conveyor frame 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 towards the rejection mechanism, so that the bulk food can fall smoothly onto the receiving plate along the movable baffle, reducing the occurrence of the bulk food accidentally falling out of the conveying mechanism.

[0032] Optionally, the partition mechanism includes multiple partitions arranged at intervals and fixed to each other. When the receiving box is located on a straight section, each partition abuts against the receiving box. The side of the receiving box is provided with multiple first notches, and the movable baffle is provided with multiple second notches. Each second notch and each first notch are normally aligned. When the receiving box is located on a straight section, each partition is respectively inserted through the corresponding first and second notches. A conveying grid area for storing bulk food is formed between each pair of adjacent partitions and the receiving box.

[0033] By adopting the above technical solution, the partition mechanism forms multiple conveying zones by dividing the spacers. At the same time, the top frame of the receiving box and the movable baffle enable multiple conveying grids to be formed 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 X-ray detector for foreign object detection. If a metal foreign object is detected, the bulk food in the corresponding conveying grid can be removed by the rejection mechanism and fall into the dropping box. The number of bulk foods contained in a single conveying grid is small, which can effectively reduce the number of qualified bulk foods that are mistakenly rejected and reduce waste.

[0034] Optionally, the drive mechanism includes a fixed plate frame, a toggle plate, a vertical guide rod, and a horizontal guide rod. The fixed plate frame is fixed between two inner plates, and the horizontal guide rod is fixedly mounted above the fixed plate frame.

[0035] The bottom end of the vertical guide rod is provided with a sleeve, through which the vertical guide rod is slidably sleeved onto the horizontal guide rod; the side of the actuating plate is provided with an extension, which is provided with a through groove for the vertical guide rod to pass through, and the end of the vertical guide rod away from the sleeve is provided with a limiting member to prevent the extension from disengaging.

[0036] The side of the extension is connected to a power assembly for driving the toggle plate to cycle; the top of the toggle plate is provided with multiple toggle blocks. When the toggle plate moves upward along the vertical guide rod, the toggle blocks enter the outside of the conveyor frame; when the toggle plate moves forward along the horizontal guide rod, the toggle blocks can drive the conveyor frame to move forward.

[0037] By adopting the above technical solution, this application controls the operation of the power component. The power component drives the actuating plate to gradually move upward along the vertical guide rod, enabling the actuating block to enter the outer side of the conveyor frame. When the actuating plate moves upward to its limit position, as the power component continues to operate, the vertical guide rod can move laterally along the horizontal guide rod. At this time, the actuating block can push the conveyor frame forward, thereby causing all conveyor frames to move forward a specific distance together. Then, after the vertical guide rod moves laterally to its limit position, as the power component continues to operate, the actuating plate gradually moves downward along the vertical guide rod, allowing the actuating block to smoothly detach from the conveyor frame. After the actuating plate moves downward to its limit position, as the power component continues to operate, the vertical guide rod can reset and retract along the horizontal guide rod, thereby causing the actuating block to move to the bottom of another conveyor frame. Based on this, intermittent movement of the conveyor frame can be achieved. When the conveyor frame moves to the inclined section, the bulk food in the conveyor area can have sufficient time to fall onto the receiving plate and be collected in the dropping box.

[0038] Optionally, the power assembly includes a drive motor fixedly mounted on a fixed plate frame and a rotary seat fixedly connected to the output end of the drive motor, the rotary seat having a through movable insertion hole;

[0039] The side of the extension is rotatably connected to a movable column, the outer diameter of which is matched with the inner diameter of the movable insertion hole; the movable column is movably inserted into the movable insertion hole, and a return spring is provided between the movable column and the rotating seat, with the return spring sleeved on the movable column.

[0040] By adopting the above technical solution, the reset spring enables an elastic connection between the rotating seat and the movable column. When the drive motor is running, the rotating seat can drive the movable column to rotate circumferentially, thereby forcing the actuating plate to move cyclically along a rectangular path to achieve intermittent movement of the conveyor frame.

[0041] Optionally, the housing assembly has a working window on its side, which faces the conveying mechanism; the working window is fitted with a removable sealing plate.

[0042] By adopting the above technical solution, the sealing plate is normally installed on the work window, which can keep the inside of the housing assembly in a sealed state and reduce the occurrence of radiation leakage to the outside. When it is necessary to disassemble and clean the receiving box, the receiving box can be easily disassembled and replaced by removing the sealing plate.

[0043] In summary, this application includes at least one of the following beneficial technical effects:

[0044] 1. Through the cooperation of the plug and the slot, the receiving box can be easily removed from the conveyor frame, and the surface of the receiving box can be easily cleaned. After cleaning, each receiving box can be quickly reinstalled on the conveyor frame, thus quickly completing the entire cleaning operation and ensuring cleanliness and hygiene during subsequent bulk food transportation.

[0045] 2. By setting an unlocking mechanism, when the conveyor frame moves to the inclined section and is directly opposite the hollow ring sleeve, the hollow ring sleeve is forced to move downward along the sliding slot. The two hollow ring sleeves can enter the outer periphery of the two plug-in columns, and the hollow ring sleeves can abut against each movable wing plate and force the movable wing plate to retract inward, further improving the convenience of the operator to disassemble and assemble the receiving box.

[0046] 3. By setting horizontal and vertical guide rods, when the drive motor is running, the rotating seat can drive the movable column to rotate circumferentially, thereby forcing the actuating plate to move laterally along the horizontal guide rod and vertically along the vertical guide rod, so that the actuating plate moves cyclically along a rectangular path to achieve intermittent movement of the conveyor frame.

[0062] The following is in conjunction with the appendix Figure 1 - Appendix Figure 12 This application will be described in further detail.

[0063] This application discloses a bulk material X-ray foreign object detection machine.

[0064] Reference Figure 1 A bulk material X-ray foreign object detection machine includes a housing assembly 1. The housing assembly 1 includes a main housing 11 fixedly mounted on a ground foundation and a control box 12 fixed to the top of the main housing 11. A display screen 13 is installed on the side of the control box 12, and a control module for controlling the operation of various components is fixed inside the control box 12. A working window is opened on the side of the main housing 11, and a sealing plate 14 is provided on the inner side of the working window. The sealing plate 14 is detachably fixed to the main housing 11 by fasteners and seals the working window.

[0065] Reference Figure 2 The housing assembly 1 contains a support mechanism 2, a conveying mechanism 3, a driving mechanism 4, and a rejection mechanism 5. Two sets of support mechanisms 2 are provided, spaced apart and fixed to the inner bottom wall of the main housing 11. A working window is positioned opposite the conveying mechanism 3 and the support mechanism 2. The support mechanism 2 includes a base frame 21 and an inner plate 22. The base frame 21 is fixed to the main housing 11, and an inner groove is formed through its side. The inner plate 22 has the same shape as the inner groove and is located inside the inner groove. Multiple connecting blocks 23 are fixed between the inner plate 22 and the base frame 21, ensuring that the inner plate 22 is fixedly mounted inside the inner groove.

[0066] Reference Figure 3 The inner plate 22 and the inner wall of the inner groove are spaced apart and form a moving area 24. The moving area 24 in this 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 loop path with the beginning and end connected. It should be noted that in this embodiment, the straight line segment 241 is located above the oblique line segment 243.

[0067] Reference Figure 4 The conveying mechanism 3 includes multiple conveyor frames 31. Connecting posts 311 are fixed to two opposite sides along the length of each conveyor frame 31, with two connecting posts 311 on each side. (See also...) Figure 2 Each connecting post 311 is inserted inside the moving area 24, and the connecting post 311 can move freely along the path of the moving area 24; two adjacent connecting posts 311 located on adjacent conveyor frames 31 are connected by hinges (not shown in the figure), thereby enabling the common movement of each conveyor frame 31. It should be noted that the hinges connecting two adjacent connecting posts 311 are in a slightly slack state, allowing the connecting post 311 to pass smoothly through the first arc segment 242 and the second arc segment 244.

[0068] Back Figure 4 Each conveyor frame 31 is equipped with a detachable receiving box 32. Specifically, two insertion slots 312 are opened through the surface of the conveyor frame 31, and the two insertion slots 312 are respectively located on the two sides of the length direction of the conveyor frame 31. Two insertion posts 321 are fixed at the bottom of the receiving box 32. The outer diameter of the insertion post 321 is equal to the inner diameter of the insertion slot 312, and the two insertion posts 321 can be matched and inserted into the two insertion slots 312 respectively.

[0069] Reference Figure 5 Multiple movable wing plates 322 are rotatably embedded at the end of the insertion post 321 away from the receiving box 32. All movable wing plates 322 are equidistantly arranged around the central axis of the insertion post 321. The rotatable connection between the movable wing plate 322 and the insertion post 321 is located at the bottom of the movable wing plate 322, and each movable wing plate 322 is provided with a first torsion spring at the rotatable connection between it and the insertion post 321. The first torsion spring can always generate a torsion force acting on the movable wing plate 322 and force the movable wing plate 322 to be normally exposed on the outer peripheral surface of the insertion post 321. The arrangement of the movable wing plates 322 can prevent the insertion post 321 from retracting or disengaging from the insertion slot 312 after it passes through the insertion slot 312.

[0070] A guide portion 323 is provided on the side of the movable wing plate 322 near the receiving box 32, and at the same time, refer to Figure 6The insertion slot 312 is provided with a guide part 313 near the inner peripheral edge of the movable wing plate 322. When it is necessary to remove the receiving box 32, force is applied to the receiving box 32 to move it away from the conveyor frame 31. The guide part 323 can abut against the guide part 313 and force each movable wing plate 322 to retract inward, thereby improving the convenience of the disassembly and assembly of the receiving box 32.

[0071] Back Figure 6 In this embodiment, the distance between the movable wing plate 322 and the bottom of the receiving box 32 is greater than the thickness of the conveyor frame 31; at the same time, referring to Figure 2 When the conveyor frame 31 is located on the straight section 241, the receiving box 32 can be located above the conveyor frame 31. Under its own weight, the receiving box 32 abuts against the conveyor frame 31. At this time, the movable wing plate 322 is spaced apart from the bottom surface of the conveyor frame 31. When the conveyor frame 31 moves to the inclined section 243, the receiving box 32 is located below the conveyor frame 31. At this time, the receiving box 32 moves downward under its own weight, which allows the movable wing plate 322 to abut against the conveyor frame 31, thereby making the receiving box 32 and the conveyor frame 31 spaced apart from each other.

[0072] Reference Figure 7 An unlocking mechanism 6 is provided between the two inner plate parts 22. The unlocking mechanism 6 includes two hollow ring sleeves 61, which are connected to each other by a connecting rod 62. A sliding block 63 is fixedly connected to the side of each hollow ring sleeve 61 away from the other hollow ring sleeve 61. Each inner plate part 22 has a sliding slot 221. The sliding block 63 is slidably installed inside the sliding slot 221, and the moving direction of the sliding block 63 is perpendicular to the inclined line segment 243. A magnetic attraction component is provided between the sliding block 63 and the inner top wall of the sliding slot 221. The magnetic attraction component includes two magnets, which are respectively embedded in the side of the sliding block 63 and the inner wall of the sliding slot 221. The magnetic poles of the two magnets are opposite, so that the sliding block 63 can be normally attracted to the inner top wall of the sliding slot 221. At this time, when the conveyor frame 31 moves in the moving area 24, the insertion post 321 will not interfere with the hollow ring sleeve 61.

[0073] Simultaneously refer to Figure 6The inner diameter of the hollow ring 61 is equal to the outer diameter of the plug-in post 321. The hollow ring 61 is located above the inclined segment 243, and the two hollow rings 61 are always directly opposite the two plug-in posts 321 of a receiving box 32. When the conveyor frame 31 moves to the inclined segment 243 and is directly opposite the hollow ring 61, the hollow ring 61 is forced to move downward along the sliding groove 221. The two hollow rings 61 can enter the outer periphery of the two plug-in posts 321. The hollow rings 61 abut against each movable wing plate 322 and force the movable wing plate 322 to retract inward. At this time, the operator can more easily pull the receiving box 32 out of the conveyor frame 31, further improving the convenience of the operator to disassemble and assemble the receiving box 32.

[0074] Back Figure 7 The drive mechanism 4 is configured to drive each conveyor frame 31 to move together, thereby forcing each receiving box 32 to move together. (See reference...) Figure 8 In this embodiment, the driving mechanism 4 includes a fixed plate frame 41, a toggle plate 42, a vertical guide rod 43, and a horizontal guide rod 44. The fixed plate frame 41 is fixed between two inner plates 22, and two support plates are fixed to the top of the fixed plate frame 41. The horizontal guide rod 44 is fixedly connected between the two support plates, thereby being fixedly mounted above the fixed plate frame 41. The axial direction of the horizontal guide rod 44 is the same as the horizontal direction.

[0075] Reference Figure 9 The bottom end of the vertical guide rod 43 is provided with an integrally formed sleeve part 431. The vertical guide rod 43 is slidably sleeved on the horizontal guide rod 44 through the sleeve part 431, so that it can move along the axial direction of the horizontal guide rod 44. The side of the actuating plate 42 is provided with an extension part 421. The extension part 421 has a vertical through groove. The vertical guide rod 43 is matched and passes through the through groove. The end of the vertical guide rod 43 away from the sleeve part 431 is fixed with a limiting member 432. The outer diameter of the limiting member 432 is larger than the inner diameter of the through groove, which is used to prevent the extension part 421 from directly detaching from the vertical guide rod 43.

[0076] The side of the extension 421 is connected to a power assembly for driving the toggle plate 42 to rotate cyclically; specifically, the power assembly 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. In this embodiment, the rotating seat 46 is located above the middle section of the transverse guide rod 44, and a through movable insertion hole 461 is provided on one side of the rotating seat 46.

[0077] The side of the extension 421 is rotatably connected to a movable column 47, the outer diameter of which is matched with the inner diameter of the movable insertion hole 461. The movable column 47 is movably inserted into the movable insertion hole 461, and a return spring 48 is sleeved on the outer periphery of the movable column 47. One end of the return spring 48 abuts against the rotatable connection between the movable column 47 and the extension 421, and the other end abuts against the rotating seat 46. The return spring 48 can always generate an elastic force acting on the movable column 47, thereby making the movable column 47 always tend to move away from the rotating seat 46.

[0078] Reference Figure 8 , Figure 9 Understandably, when the drive motor 45 operates and its output shaft rotates circumferentially, it drives the extension 421 to move upward along the vertical guide rod 43, which is the first movement path. After the extension 421 moves upward to its limit position, the vertical guide rod 43 is subjected to force and moves along the horizontal guide rod 44, which is the second movement path. Then, after the vertical guide rod 43 moves laterally to its limit position, the extension 421 can move downward along the vertical guide rod 43, which is the third movement path. After the extension 421 moves downward to its limit position, the vertical guide rod 43 is subjected to force and retracts along the horizontal guide rod 44, which is the fourth movement path. After passing through the first, second, third, and fourth movement paths, the extension 421 returns to its initial position, thus completing one action cycle.

[0079] The top of the toggle plate 42 is provided with multiple sets of toggle blocks 422, see reference. Figure 10 In this embodiment, each set of levers 422 contains two levers 422. When the drive motor 45 operates and the extension 421 passes through the first moving path, adjacent levers 422 can enter between the movable baffle 324 and the conveyor frame 31. Then, after passing through the second moving path, the levers 422 can drive all the conveyor frames 31 to move forward, thereby causing each receiving box 32 to move sequentially to below the X-ray detector for foreign object detection. It should be noted that during the time period when the extension 421 passes through the third and fourth moving paths, the receiving box 32 located in the first arc segment 242 can maintain an inclined state.

[0080] Back Figure 4The receiving box 32 has a concave cross-sectional shape, and one side of the receiving box 32 is open. A movable baffle 324 is rotatably installed on the open side of the receiving box 32. A second torsion spring is provided between the movable baffle 324 and the rotating part of the receiving box 32. The second torsion spring can always generate a torsion force acting on the movable baffle 324, thereby forcing the movable baffle 324 to normally seal the open side of the receiving box 32, so that the receiving box 32 and the movable baffle 324 together form a storage area 325 for storing bulk food. Here, the bottom of the movable baffle 324 has a load-bearing part 3241 extending to the bottom of the conveyor frame 31.

[0081] Simultaneously refer to Figure 1 In this embodiment, the length of the main housing 11 is greater than the length of the control box 12. The control box 12 is located at the middle of the top of the main housing 11, so that the two sides of the main housing 11 in the length direction can be exposed to the control box 12. A feeding port 111 is partially opened on the top surface of the exposed part of the main housing 11, and a feeding chamber 15 is fixedly mounted in the feeding port 111. The feeding chamber 15 is located above the straight section 241 and is directly opposite a receiving box 32. The bulk snacks processed in the front-end process can enter the feeding chamber 15 and fall smoothly into the storage area 325.

[0082] Back Figure 2 , Figure 3 When the conveyor frame 31 moves from the straight section 241 to the first arc section 242 under the drive of the drive mechanism 4, the receiving box 32 will gradually flip to an inclined state. It should be noted that when the receiving box 32 is located in the first arc section 242, the movable baffle 324 will be located on the side of the receiving box 32 away from the feeding chamber 15. (Refer to...) Figure 7 A fixed support column 222 is fixedly mounted between the two inner plates 22, and the fixed support column 222 is located on the outside of the first arc segment 242; at the same time, refer to Figure 11 When the receiving box 32 is located in the first arc segment 242, the load-bearing part 3241 of the movable baffle 324 can abut against the fixed rod column 222, thereby causing the movable baffle 324 to flip away from the feeding chamber 15, so that the bulk snacks in the storage area 325 can fall along the movable baffle 324 to the next station.

[0083] Back Figure 2 The top of the two base frames 21 is fixedly supported by a partition mechanism 7. The partition mechanism 7 includes multiple partition plates 71 arranged at intervals. All partition plates 71 are connected and fixed by a shaft member 72, thereby connecting and fixing each partition plate 71 to each other. A conveying channel 73 is formed between adjacent partition plates 71 that are spaced apart from each other.

[0084] Additionally, refer to Figure 4The movable baffle 324 has multiple second notches 3242, and the receiving box 32 has multiple first notches 326 on its side. The number of first notches 326 and the number of second notches 3242 are equal to the number of partition plates 71. Each first notch 326 and each second notch 3242 is normally positioned opposite each other. (See also...) Figure 12 When the receiving box 32 moves to the straight section 241, the partition plate 71 abuts against the inner surface of the receiving box 32, and each partition plate 71 can be respectively inserted into the first notch 326 and the second notch 3242 facing each other. At this time, a conveying grid area 74 for storing bulk food is formed between each pair of adjacent partition plates 71 and the receiving box 32.

[0085] Back Figure 2 It should also be noted that each partition plate 71 is hinged to a hinge plate 75 on the side closest to the first arc segment 242. Under its own weight, the hinge plate 75 normally rests against the receiving box 32 of the first arc segment 242. Due to the free rotation setting of the hinge plate 75, the hinge plate 75 can rotate to avoid the receiving box 32 when it moves, reducing the possibility of interference between the receiving box 32 and the partition mechanism 7.

[0086] The X-ray detector is fixed inside the control box 12, with the detector head facing downwards and directly opposite one of the receiving boxes 32. The X-ray detector is configured to detect bulk food in each conveying compartment 74 on the receiving box 32, detect bulk food containing metal foreign objects, and then remove the bulk food in the conveying compartment 74 by signal control of the rejection mechanism 5 to ensure food safety.

[0087] The rejection mechanism 5 is located outside the second arc segment 244. The rejection mechanism 5 includes multiple rejection units, and the number of rejection units is equal to the number of conveying channels 73. Each rejection unit includes a support plate 51 and a pneumatic component 52. The support plate 51 is rotatably mounted on the side of two base frames 21. In this embodiment, the pneumatic component 52 is a cylinder. The fixed end of the pneumatic component 52 is hinged to the inner bottom wall of the main housing 11, and the movable end of the pneumatic component 52 is hinged to the support plate 51.

[0088] Simultaneously refer to Figure 1 The main housing 11 has an outlet 112 on the side away from the inlet 111. An outlet conveyor 8 is installed at the outlet 112. The outlet conveyor 8 is located at the rear end of the conveying mechanism 3, and the receiving plate 51 is normally inclined downward toward the outlet conveyor 8. In normal use, the top of the receiving plate 51 is tilted directly opposite the receiving box 32 located on the first arc segment 242 to receive bulk snacks falling from the movable baffle 324.

[0089] In addition, a drop box 53 is provided between the two base frames 21, and the drop box 53 is located below the first arc segment 242. If a certain conveying grid 74 is detected by the X-ray detector to contain a metal foreign object, the corresponding pneumatic component 52 can be activated and force the receiving plate 51 to flip, so that the receiving plate 51 can be flipped to tilt downward toward the drop box 53. At this time, the bulk snacks in the conveying grid 74 containing the metal foreign object can fall into the drop box 53 after falling onto the receiving plate 51 for collection, so as to facilitate the collection and cleaning of defective products.

[0090] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
