Description

Technical Field

[0001] The invention relates to the technical field of jujube meat detection, and more specifically, to a device for detecting foreign matter in jujube meat. Background Art

[0002] Jujube meat is a nutritious food that can be eaten as a common food or used as a Chinese medicinal material. It has many functions and effects that are beneficial to human health. However, it is worth noting that during the growth and processing of jujube plants, they may be invaded by borers. At the same time, in order to improve the eating experience, removing the jujube pits has become a necessary processing step. Therefore, the use of advanced testing equipment to accurately identify and remove foreign matter in jujube meat, including borer residues and jujube pits, has become a key link in ensuring the quality and safety of jujube meat.

[0003] Among the current detection technologies, X-ray cameras are widely used to detect foreign matter in jujube pulp. However, the traditional method tends to perform batch detection and classification of jujube pulp. Although this method is easy to operate, it is easy to cause misjudgment and mistakenly classify jujube pulp with good quality as foreign matter, resulting in inaccurate detection. On the other hand, if the strategy of carefully detecting jujube pulp one by one is adopted, although it can improve accuracy to a certain extent, it will inevitably sacrifice detection efficiency and prolong the time of the entire detection process.

[0034] Example 1: Please refer to Figure 1-11 Structural schematic diagram, the present invention provides the following technical solutions:

[0035] A device for detecting foreign matter in jujube flesh comprises a frame 1, wherein the frame 1 comprises two horizontal bars 101 above, legs 102 placed on the ground are arranged below the horizontal bars 101, and a shell 2 is arranged above the horizontal bars 101.

[0036] Two conveying mechanisms 3 for transporting jujube meat are arranged in parallel between the two cross-frame rods 101, one conveying mechanism 3 is located at the feeding port, and the other conveying mechanism 3 is located at the discharging port. The conveying mechanism 3 includes two conveying shafts 301 rotatably arranged between the cross-frame rods 101, a conveyor belt 302 is wound between the two conveying shafts 301, and the cross-frame rods 101 are higher than the surface of the conveyor belt 302, one cross-frame rod 101 is connected to the rotating shaft of the transmission electric cylinder 303, and the transmission electric cylinder 303 is fixed on the side of the cross-frame rod 101; specifically, the transmission electric cylinder 303 provides power to drive a conveying shaft 301 to rotate, and the conveying shaft 301 drives the conveyor belt 302 to rotate, and the jujube meat is placed on the conveyor belt 302, and the conveyor belt 302 transports the jujube meat, and the cross-frame rod 101 is higher than the surface of the conveyor belt 302 to prevent the jujube meat from moving to the outside of the conveying mechanism 3.

[0037] An X-ray machine 4 for detecting foreign matter in jujube meat is provided under the top cover of the shell 2. A hydraulic cylinder 5 is also provided under the top cover of the shell 2. A middle shift plate 6 is provided at the end of the telescopic shaft of the hydraulic cylinder 5, and two sliding columns 7 are provided on both sides of the lower surface of the middle shift plate 6. The sliding columns 7 on both sides are respectively slidably provided on two cross-frame rods 101. Smooth blocks 8 are slidably provided on the middle shift plate 6 and located just above the inner sides of the two cross-frame rods 101. A guide plate 9 for guiding the jujube meat is rotatably provided at the lower end of the smooth block 8, so the outward end edge of the guide plate 9 is flush with the inner side of the cross-frame rod 101, and the two guide plates 9 are symmetrically arranged obliquely, and the direction of the guide plate 9 A flat plate 10 having the same height as the guide plate 9 is rotatably provided at the inner end edge, an L-shaped side column 11 is provided at the center of the flat plate 10, and the upper end of the L-shaped side column 11 is slidably provided on the middle shift plate 6, a short connecting rod 12 is rotatably provided on the upper end surface of the L-shaped side column 11, a double-end rod 13 is rotatably provided at the end of the short connecting rod 12, a smooth rod 14 is provided above the middle of the double-end rod 13, a smooth seat 15 is slidably sleeved on the smooth rod 14, a push rod 16 is fixedly provided at the end of the smooth seat 15, a frame seat 18 is provided between the two long side surfaces inside the outer shell 2, a hydraulic cylinder 17 is provided above the frame seat 18, and the telescopic shaft of the hydraulic cylinder 17 is connected to the middle of the push rod 16.

[0038] Specifically, when the jujube meat needs to be inspected one by one, the telescopic shaft of the hydraulic cylinder 1 5 is extended to drive the middle shift plate 6 to slide to the lower position, even if the guide plate 9 is three millimeters away from the conveyor belt 302, and the hydraulic cylinder 2 17 is started. The power is transmitted through the push rod 16, the smooth seat 15, the smooth rod 14 and the short connecting rod 12 to make the two L-side columns 11 slide on the middle shift plate 6, thereby adjusting the distance between the two flat plates 10 so that the distance between the two flat plates 10 is slightly larger than the diameter of the jujube meat. When the jujube meat on the conveyor belt 302 passes through the two guide plates 9, the guide plates 9 guide the jujube meat, so that the jujube meat enters between the two flat plates 10 and is arranged in a queue, and the X-ray machine 4 inspects the jujube meat one by one.

[0039] When it is necessary to inspect the jujube meat in batches, the telescopic shaft of the hydraulic cylinder 5 is retracted to drive the middle shift plate 6 to slide to the upper position. The middle shift plate 6 moves the guide plate 9 and the flat plate 10 away from the conveyor belt 302, so the guide plate 9 and the flat plate 10 no longer have any effect on the jujube meat on the conveyor belt 302. The jujube meat is inspected in batches through the bottom of the X-ray machine 4. During this process, the L side column 11, the short connecting rod 12, the double-end rod 13 and the smooth rod 14 rise synchronously with the middle shift plate 6, and the smooth rod 14 slides in the smooth seat 15.

[0040] A translation rod 19 is fixedly provided at both ends of the push rod 16, and a translation slide 20 is slidably sleeved on the translation rod 19. The translation slide 20 is fixedly provided on the inner long side surface of the shell 2. A long connecting rod 21 twice the length of the short connecting rod 12 is rotatably provided at the end of the translation rod 19, and a baffle 22 for blocking overlapping jujube meat is rotatably provided at the lower end of the long connecting rod 21. Slide grooves 23 are vertically provided on the two long side surfaces inside the shell 2, and the two sides of the baffle 22 are slidably provided in the two slide grooves 23 respectively.

[0041] Taking into account that when the X-ray machine 4 detects the jujube flesh, due to the reason of image overlap, the overlapping of the jujube flesh will affect the detection accuracy and cause detection errors. Specifically, the hydraulic cylinder 17 is started to adjust the distance between the two flat plates 10. The telescopic shaft of the hydraulic cylinder 17 drives the push rod 16 to move. The push rod 16 drives the translation rod 19 to slide in the translation slide 20, and then transmits power through the long connecting rod 21 to drive the baffle 22 to slide up and down in the slide groove 23, thereby adjusting the distance from the baffle 22 to the surface of the conveyor belt 302. Since the length of the long connecting rod 21 is twice the length of the short connecting rod 12, the angle between the long connecting rod 21 and the baffle 22 is ensured. It is equal to the angle between the sliding directions of the short connecting rod 12 and the L side column 11, that is, the sliding speed of the baffle 22 can be twice the sliding speed of the flat plate 10. Therefore, the distance between the two flat plates 10 is always equal to the distance from the bottom of the baffle 22 to the conveyor belt 302. Therefore, after adjusting the distance between the two flat plates 10 according to the diameter of the jujube meat in this batch, the distance from the baffle 22 to the conveyor belt 302 can be adjusted conveniently and quickly. When the jujube meat on the conveyor belt 302 passes through the baffle 22, the baffle 22 will block the jujube meat overlapping on the top to the conveyor belt 302, so that all the jujube meat is spread flat on the conveyor belt 302, thereby improving the accuracy of the jujube meat detection by the X-ray machine 4.

[0042] Two top flat triangular plates 24 are symmetrically arranged between the two horizontal bars 101 and between the two conveyor belts 302, and the upper plane of the top flat triangular plates 24 is flush with the upper plane of the conveyor belt 302. The top flat triangular plates 24 can allow the jujube meat to pass smoothly through the gap between the two 3. A partition plate 25 for blocking the jujube meat is slidably arranged between the two top flat triangular plates 24. A cross beam 26 is arranged between the two horizontal bars 101, and an electric cylinder 27 is arranged below the cross beam 26. The telescopic shaft of the electric cylinder 27 is connected to the partition plate 25.

[0043] Considering the need to screen out the jujube meat with foreign matter, it is necessary to separate the batch of jujube meat into jujube meat piles, and then check and screen the jujube meat piles with foreign matter and the jujube meat piles without foreign matter, so as to improve the detection efficiency. Specifically, when the electric cylinder 27 is extended and contracted, the partition plate 25 is driven to extend above the two conveyor belts 302, so the partition plate 25 blocks the jujube meat above the conveyor belt 302 at the inlet from advancing, and the conveyor belt 302 at the outlet continues to transport the isolated jujube meat piles to the bottom of the X-ray machine 4 for detection, thereby achieving the purpose of separating the jujube meat into jujube meat piles for detection. If the separated jujube meat is found to have foreign matter, all the jujube meat in this pile can be removed. The flat plate 10 is provided with a long notch 1001 for inserting the partition plate 25. When the middle shift plate 6 and the flat plate 10 are in the lower position, the long notch 1001 makes room for the rise of the partition plate 25.

[0044] The ends of the two horizontal beams 101 are both horizontally provided with horizontal side plates 28, and a dividing plate 29 for batch screening of foreign matter in jujube pulp is rotatably provided between the two horizontal side plates 28. A rocker arm 30 is fixedly provided at the end of the rotating shaft of the dividing plate 29, and a rotating connecting rod 31 is rotatably provided at the end of the rocker arm 30. A hydraulic cylinder 32 is provided on the side surface of one of the horizontal beams 101, and the telescopic shaft of the hydraulic cylinder 32 is hinged to the end of the rotating connecting rod 31.

[0045] Specifically, when the X-ray machine 4 detects that there is no foreign matter in the jujube meat, the telescopic shaft of the hydraulic cylinder three 32 is in a retracted state, and power is transmitted through the rotating connecting rod 31, so that the side of the dividing plate one 29 close to the dividing plate two 34 is higher than the side away from the dividing plate two 34, so that the intact jujube meat slides off from the side of the dividing plate one 29 away from the dividing plate two 34; when the X-ray machine 4 detects that there is foreign matter in the jujube meat, the telescopic shaft of the hydraulic cylinder three 32 is in an extended state, so that the side of the dividing plate one 29 close to the dividing plate two 34 is lower than the side away from the dividing plate two 34, so the jujube meat with foreign matter slides off from the side of the dividing plate one 29 close to the dividing plate two 34.

[0046] The ends of the two horizontal bars 101 are also vertically provided with vertical side plates 33, and a dividing plate 2 34 for screening foreign objects in the jujube pulp one by one is rotatably provided between the two vertical side plates 33. A gear 35 is provided on the rotating shaft of the dividing plate 2 34, and the gear 35 is meshed with a rack 36. The rack 36 is fixed to one end of a long sliding rod 37, and the middle part of the long sliding rod 37 is slidably provided on the side of the horizontal bar 101. The other end of the long sliding rod 37 is rotatably provided with a side connecting rod 38, and the end of the side connecting rod 38 is rotatably provided with an extension rod 39, which passes through the horizontal bar 101 and is connected to a sliding column 7.

[0047] Considering that when foreign matter is detected in the jujube meat, the jujube meat pile detected in batches and the jujube meat detected individually both slide down from the side of the dividing plate 1 29 close to the dividing plate 2 34, it is necessary to classify the two again; when the jujube meat pile is detected, the middle shift plate 6 is in the upper position, so the sliding column 7 drives the extension rod 39 to be in the upper position as well, and the power is transmitted through the side connecting rod 38, the long sliding rod 37 and the rack 36, so that the rack 36 rotates counterclockwise to the limit position, even if the dividing plate 2 34 is in a vertical state, the jujube meat pile with foreign matter falls from the dividing plate 1 29. When the jujube meat is inspected one by one, the middle shift plate 6 is in the lower position, and the rack 36 is rotated clockwise to the limit position according to the above principle, even if the side of the dividing plate 234 away from the dividing plate 29 is lower than the side close to the dividing plate 29, and the dividing plate 234 and the dividing plate 23 are coplanar, the single pile of jujube meat with foreign matter passes through the dividing plate 29 and then slides from the side of the dividing plate 234 away from the dividing plate 29, thereby achieving the purpose of screening out the single jujube meat with foreign matter.

[0048] The working principle of the detection device for foreign matter in jujube flesh provided by the present invention is as follows:

[0049] According to the size of the jujube meat to be tested in batches, the hydraulic cylinder 17 is started, and the power is transmitted through the push rod 16, the smooth seat 15, the smooth rod 14 and the short connecting rod 12, so that the two L side columns 11 slide on the middle shift plate 6, thereby adjusting the distance between the two flat plates 10, so that the distance between the two flat plates 10 is slightly larger than the diameter of the jujube meat. At the same time, the push rod 16 drives the translation rod 19 to slide in the translation slide seat 20, and then transmits power through the long connecting rod 21 to drive the baffle 22 to slide in the slide groove 23, thereby adjusting the distance between the baffle 22 and the surface of the conveyor belt 302. The distance from the baffle 22 to the surface of the conveyor belt 302 is equal to the distance between the two flat plates 10; the hydraulic cylinder 15 is started to drive the middle shift plate 6 to slide to the upper position, and the middle shift plate 6 brings the guide plate 9 and the flat plate 10 away from the conveyor belt 302, so the guide plate 9 and the flat plate 10 have no effect on the jujube meat on the conveyor belt 302; at the same time, the middle shift plate 6 causes the sliding column 7 to drive the extension rod 39 to be in the upper position, and the power is transmitted through the side connecting rod 38, the long sliding rod 37 and the rack 36, so that the rack 36 rotates counterclockwise to the extreme position, even if the dividing plate 2 34 is in a vertical state.

[0050] A large amount of jujube meat is placed on the conveyor belt 302 of the conveying mechanism 3 at the feeding port at the same time. When the conveyor belt 302 drives the jujube meat to pass through the partition plate 25, the telescopic shaft of the electric cylinder 27 drives the partition plate 25 to rise periodically, so as to separate the large amount of jujube meat into multiple batches of jujube meat piles. The conveyor belt 302 at the feeding port carries the jujube meat piles through the baffle 22. The baffle 22 blocks the jujube meat overlapping on the top onto the conveyor belt 302, so that all the jujube meat is spread flat on the conveyor belt 302. When the jujube meat is inspected by the X-ray machine 4, the accuracy of the X-ray machine 4 in inspecting the jujube meat can be improved. When the X-ray machine 4 detects that there is no foreign matter in the jujube meat pile, the telescopic shaft of the hydraulic cylinder three 32 is in a contracted state, and the power is transmitted through the rotating connecting rod 31, so that the side of the dividing plate one 29 close to the dividing plate two 34 is higher than the side away from the dividing plate two 34, so that the intact jujube meat slides from the side of the dividing plate one 29 away from the dividing plate two 34; when the X-ray machine 4 detects that there is foreign matter in the jujube meat, the telescopic shaft of the hydraulic cylinder three 32 is in an extended state, so that the side of the dividing plate one 29 close to the dividing plate two 34 is lower than the side away from the dividing plate two 34, so the jujube meat pile with foreign matter slides from the dividing plate one 29 and the dividing plate two 34. Therefore, a large amount of jujube meat can be efficiently divided into jujube meat piles and then quickly detected and screened. In the jujube meat pile with foreign matter, there are still intact single jujube meats, so the jujube meat pile with foreign matter needs to be detected and screened again.

[0051] Start hydraulic cylinder 5 to drive the middle shift plate 6 to slide to the lower position, even if the guide plate 9 is three millimeters away from the conveyor belt 302. At the same time, through the same principle, the rack 36 is rotated clockwise to the extreme position, even if the side of the dividing plate 2 34 away from the dividing plate 1 29 is lower than the side close to the dividing plate 1 29, and the dividing plate 2 34 and the dividing plate 1 29 are coplanar.

[0052] The jujube meat pile containing foreign matter is placed again on the conveyor belt 302 of the conveying mechanism 3 at the feed inlet. When the jujube meat on the conveyor belt 302 passes through the two guide plates 9, the guide plates 9 guide the jujube meat, so that the jujube meat enters between the two flat plates 10 and is arranged in a team. The periodically rising partition plate 25 isolates the jujube meat pile into a single state, so the jujube meat enters the X-ray machine 4 one by one for detection; when it is detected that there is no foreign matter in a single jujube meat, the telescopic shaft of the hydraulic cylinder three 32 is still in a contracted state, and the same principle as above is used, so the intact single jujube meat still slides from the side of the dividing plate one 29 away from the dividing plate two 34; when it is detected that there is no foreign matter in a single jujube meat, the telescopic shaft of the hydraulic cylinder three 32 is still in an extended state, and the same principle as above is used, the single jujube meat pile with foreign matter passes through the dividing plate one 29 and then slides from the side of the dividing plate two 34 away from the dividing plate one 29, thereby completing the final detection and screening of the jujube meat.

[0053] Embodiment 2: Based on the specific embodiment 1, the difference of this embodiment is that:

[0054] A motor 40 is provided above the top cover of the outer shell 2 and between the X-ray machine 4 and the hydraulic cylinder 5. The rotating shaft of the motor 40 passes through the top cover of the outer shell 2. A fan 41 for air-drying the jujube flesh is provided below the top cover of the outer shell 2 and directly below the motor 40. The rotating shaft of the motor 40 is connected to the center of the impeller of the fan 41. A heating lamp 42 for heating and drying the jujube flesh is provided below the top cover of the outer shell 2 and on both sides of the fan 41. Concealed air holes 43 for ventilation are provided on the sides of the outer shell 2. The rays of the X-ray machine 4 are irradiated to the outside without passing through the controller 44.

[0055] Considering that moisture will absorb X-rays and cause the clarity and contrast of the image to decrease, when there is moisture on the surface of the jujube flesh, before the jujube flesh enters under the X-ray machine 4, the motor 40 is started to drive the fan 41 to rotate to air-dry the jujube flesh, and the heating lamp 42 is started to increase the temperature, thereby accelerating the drying effect of the jujube flesh.

[0056] A controller 44 for operation control is provided above the top cover of the housing 2, and the controller 44 operates and controls the device.

[0057] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
