Description

Technical Field

[0001] This invention relates to the field of food testing technology, specifically to an automatic sampling structure for rapid food testing. Background Technology

[0002] New Year's steamed buns are a traditional folk craft and a specialty food of Huozhou City, Shanxi Province. They represent the hopes and blessings of the people of Huozhou and embody the wisdom and talent of the people of Shanxi. They are one of the folk art forms with northern characteristics and are also an important part of Huozhou's intangible cultural heritage. They are known as "a delicacy on the tip of the tongue" and "a delicacy on the fingertips".

[0003] To test the quality of whole New Year's buns, it is necessary to take samples for testing. However, when sampling New Year's buns, because they are embedded with other ingredients such as red dates and raisins, the embedding is not very tight. It is easy to pick up buns with separated ingredients during sampling, which makes the sampling test results unrepresentative. Moreover, during the sampling process, New Year's bun fragments may stick to the sampler, which may cause sampling interference and cross-contamination when sampling the next New Year's bun or food.

[0004] Therefore, based on the above problems, we have invented an automatic sampling structure for rapid food testing. Summary of the Invention

[0020] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an automatic sampling structure for rapid food detection.

[0021] like Figures 1-9As shown, an automatic sampling structure for rapid food testing includes a main L-shaped support plate 1, a robotic arm 2 mounted on the main L-shaped support plate 1, a gripping mechanism 3 for gripping steamed buns on the robotic arm 2, two T-shaped mounting plates 4 fixed to the upper end of the main L-shaped support plate 1, two placement rollers 5 installed between the two T-shaped mounting plates 4, and the two placement rollers 5 connected by a conveyor belt, a secondary L-shaped support plate 6 mounted outside the main L-shaped support plate 1, a base plate 7 and an elastic plate 8 above the secondary L-shaped support plate 6, and an elastic plate 8. The elastic plate 8 is slidably connected to the base plate 7. Two transfer rollers 9 are provided on both sides of the base plate 7. The four transfer rollers 9 are located on both sides of the base plate 7. The two transfer rollers 9 on the same side are connected by a conveyor belt. The transfer rollers 9 are rotatably installed with the main L-shaped support plate 1. The base plate 7 is fixedly installed with the main L-shaped support plate 1. A pushing mechanism 11 for pushing the steamed buns is provided between the main L-shaped support plate 1 and the secondary L-shaped support plate 6. An elastic element 10 for buffering the elastic plate 8 is provided between the base plate 7 and the elastic plate 8.

[0022] To prevent crumbs from sticking to the sampler during the handling of New Year's buns, a gripping mechanism 3 is provided. The gripping mechanism 3 includes a mounting plate 12 mounted to the robotic arm 2. Two horizontal plates 13 are mounted on the mounting plate 12, and two rotating shafts 14 are rotatably mounted between the two horizontal plates 13. Drive gears 16 are coaxially mounted on the outside of each of the two rotating shafts 14, meshing with each other. Clamping arms 17 are fixed to the outside of each of the two rotating shafts 14. A drive motor 15 is mounted on the horizontal plates 13, and the drive shaft of the drive motor 15 rotates through the horizontal plates 13 and is coaxially mounted with the rotating shafts 14. Clamping plates 18 are mounted on each of the two clamping arms 17, and a cleaning mechanism 21 for cleaning the clamping plates 18 is provided between the two clamping arms 17. It should be noted that the cleaning mechanism 21 includes… A vertical plate 55 is fixed to two horizontal plates 13. The vertical plate 55 has a slot 23. A threaded rod 24 is rotatably installed in the slot 23. A threaded block 25 is threaded on the outside of the threaded rod 24. The threaded block 25 is slidably connected to the slot 23.

A connecting plate 19 is fixed to one end of the rotating plate 22. Adsorption plates 20 are fixed to both ends of the connecting plate 19. The two adsorption plates 20 are matched with two clamping plates 18 respectively. A negative pressure suction cup 28 is installed on the adsorption plate 20. The negative pressure suction cup 28 is connected to an external negative pressure device.

[0023] Through the above technical features: the cleaning motor 26 drives the threaded rod 24 to rotate, the threaded rod 24 drives the threaded block 25 to move, the threaded block 25 drives the rotating plate 22 to rotate through the deflection plate 27, the rotating plate 22 drives the adsorption plate 20 to rotate through the connecting plate 19, and the adsorption plate 20 drives the negative pressure suction cup 28 to move.

The sampling effect of the New Year's buns is better, and there is no risk of sampling interference and cross-contamination.

[0024] To automatically identify intact New Year's buns, a pushing mechanism 11 is provided. The pushing mechanism 11 includes an L-shaped mounting plate 46 installed above the secondary L-shaped support plate 6. Both ends of the L-shaped mounting plate 46 are fixed to the main L-shaped support plate 1 and the secondary L-shaped support plate 6, respectively. A lifting shaft 56 is provided between the L-shaped mounting plate 46 and the secondary L-shaped support plate 6. A sleeve 50 is slidably fitted onto the lifting shaft 56. Both ends of the sleeve 50 are rotatably connected to the secondary L-shaped support plate 6 and the L-shaped mounting plate 46, respectively. A telescopic motor 51 is fixed to the lower end of the secondary L-shaped support plate 6. The telescopic shaft of the telescopic motor 51 passes through the secondary L-shaped support plate 6 and is rotatably mounted to the lifting shaft 56. The upper end of the lifting shaft 56 passes through the L-shaped mounting plate 46. A turntable 43 is provided above the mounting plate 46. A toothed ring 45 is provided outside the lifting shaft 56. The toothed ring 45 is fixed to the turntable 43 by multiple L-shaped connecting shafts 44. A switching gear 48 is fixed at the upper end of the lifting shaft 56. Multiple limiting rods 49 are fixed on the turntable 43. The multiple limiting rods 49 are matched with the switching gear 48. An internal gear 47 is rotatably mounted on the L-shaped mounting plate 46. The internal gear 47 is meshed with the toothed ring 45. The internal gear 47 is matched with the switching gear 48. A transmission shaft 33 is rotatably passed through the main L-shaped support plate 1. Both ends of one of the placement rollers 5 rotatably pass through the T-shaped mounting plate 4 and are respectively connected to the two transmission shafts 33 through the first bevel gear set 34.

[0025] In this invention, the first bevel gear set 34 includes a first bevel gear 35 and a second bevel gear 36 that mesh with each other. The first bevel gear 35 is coaxially mounted with the drive shaft 33, and the second bevel gear 36 is coaxially mounted with the placement roller 5. One end of each of the two transfer rollers 9 rotatably passes through the main L-shaped support plate 1 and is respectively connected to the two drive shafts 33 via the second bevel gear set 37. Notably, the second bevel gear set 37 includes a third bevel gear 38 and a fourth bevel gear 39 that mesh with each other. The third bevel gear 38 is coaxially mounted with the drive shaft 33, and the fourth bevel gear 39 is coaxially mounted with the transfer rollers 9. The drive shaft 33 is connected to the sleeve 50 via... The transmission mechanism 52 is used for transmission connection. It should be noted that the transmission mechanism 52 includes a first pulley 53 and a second pulley 54. The first pulley 53 is coaxially mounted with the transmission shaft 33, and the second pulley 54 is coaxially mounted with the sleeve 50. The first pulley 53 and the second pulley 54 are connected by a synchronous belt. The upper end of the turntable 43 is fixed with a deflector shaft 42. The upper end of the deflector shaft 42 rotates through the base plate 7 and is mounted with a deflector plate 41. The inner wall of the main L-shaped support plate 1 is fixed with a drive plate 32. The lower end of the drive plate 32 is mounted with a transmission motor 40. The drive shaft of the transmission motor 40 rotates through the drive plate 32 and is coaxially mounted with the transmission shaft 33.

[0026] In this invention, the elastic element 10 includes a buffer groove 29 disposed between the base plate 7 and the elastic plate 8. Two contact plates 31 are provided in the buffer groove 29. The two contact plates 31 are fixed to the upper and lower inner sidewalls of the buffer groove 29 respectively. A buffer spring 30 is installed in the buffer groove 29. The two ends of the buffer spring 30 are fixed to the upper and lower inner sidewalls of the buffer groove 29 respectively. Both contact plates 31 are electrically connected to the telescopic motor 51.

[0027] Through the above technical features: the drive motor 40 drives the drive shaft 33 to rotate, the drive shaft 33 drives the placement roller 5 to rotate, the placement roller 5 drives the conveyor belt on it to rotate, and at the same time, the drive shaft 33 drives the transfer roller 9 to rotate, the transfer roller 9 drives the conveyor belt on it to rotate, so that the two conveyor belts on both sides of the bottom plate 7 drive in opposite directions. The New Year's bun sampled by the gripping mechanism 3 is placed on the conveyor belt on the placement roller 5, and the conveyor belt transports it to the elastic plate 8. If the ingredients embedded in the New Year's bun fall off, the New Year's bun is incomplete. At this time, the weight of the New Year's bun itself is insufficient, pressing the elastic plate 8 to move down, but not enough to make the two contact plates 31 abut against each other. At this time, the drive shaft 33 drives the sleeve 50 to rotate, the sleeve 50 drives the lifting shaft 56 to rotate, the lifting shaft 56 drives the switching gear 48 to rotate, the switching gear 48 drives the turntable 43 to rotate through the limit rod 49, the turntable 43 drives the actuating plate 41 to rotate through the actuating shaft 42, and the actuating plate 41 can then move the New Year's bun on the elastic plate 8 to a certain position. The steamed buns are conveyed on the side conveyor belt. If the buns are intact, their weight is within acceptable limits. The pressing elastic plate 8 moves down, causing the two contact plates 31 to come into contact. At this time, the power to the drive motor 15 is turned on, and the drive motor 15 drives the lifting shaft 56 to rise and fall. The lifting shaft 56 drives the switching gear 48 to rise and fall until the switching gear 48 meshes with the internal gear 47. At this time, the transmission shaft 33 drives the sleeve 50 to rotate. The sleeve 50 drives the switching gear 48 to rotate through the lifting shaft 56. The switching gear 48 drives the internal gear 47 to rotate. When wheel 47 rotates, internal gear 47 drives gear ring 45 to rotate in the opposite direction. Gear ring 45 drives turntable 43 to rotate in the opposite direction through L-shaped connecting shaft 44. Turntable 43 drives actuating shaft 42 to drive actuating plate 41 to rotate in the opposite direction. Actuating plate 41 can then move the New Year's buns on elastic plate 8 to the conveyor belt on the other side for transport. This allows for the classification and sampling of New Year's buns based on their integrity, avoiding the occurrence of incomplete New Year's buns during sampling and testing. The results of New Year's bun sampling and testing are more accurate and representative.

[0028] Working principle: (1) Cleaning the sampler: The cleaning motor 26 drives the threaded rod 24 to rotate, the threaded rod 24 drives the threaded block 25 to move, the threaded block 25 drives the rotating plate 22 to rotate through the deflection plate 27, the rotating plate 22 drives the adsorption plate 20 to rotate through the connecting plate 19, the adsorption plate 20 drives the negative pressure suction cup 28 to move, and the negative pressure suction cup 28 can clean the surface of the clamping plate 18 when it moves, so as to avoid the New Year's bread fragments adhering to the surface of the clamping plate 18 after sampling the New Year's bread, thus achieving a better sampling effect for the New Year's bread and avoiding the risk of sampling interference and cross-contamination. (2) Classification of sampled New Year's buns: The drive motor 40 drives the drive shaft 33 to rotate, the drive shaft 33 drives the placement roller 5 to rotate, and the placement roller 5 drives the conveyor belt on it. At the same time, the drive shaft 33 drives the transfer roller 9 to rotate, and the transfer roller 9 drives the conveyor belt on it, so that the two conveyor belts on both sides of the bottom plate 7 drive in opposite directions. The New Year's buns sampled by the gripping mechanism 3 are placed on the conveyor belt on the placement roller 5, and the conveyor belt transports them to the elastic plate 8. If the New Year's buns are... If the embedded ingredients fall off, the New Year's bun will be incomplete. At this time, the weight of the bun itself is insufficient to press down the elastic plate 8, but it is not enough to make the two contact plates 31 come into contact. At this time, the transmission shaft 33 drives the sleeve 50 to rotate, the sleeve 50 drives the lifting shaft 56 to rotate, the lifting shaft 56 drives the switching gear 48 to rotate, the switching gear 48 drives the turntable 43 to rotate through the limit rod 49, and the turntable 43 drives the actuating plate 41 to rotate through the actuating shaft 42. The actuating plate 41 can then move the New Year's bun on the elastic plate 8 to... The steamed buns are conveyed on one side of the conveyor belt. If the buns are intact, their weight is within acceptable limits. The pressing elastic plate 8 moves down, causing the two contact plates 31 to come into contact. At this time, the power to the drive motor 15 is turned on, and the drive motor 15 drives the lifting shaft 56 to rise and fall. The lifting shaft 56 drives the switching gear 48 to rise and fall until the switching gear 48 meshes with the inner gear 47. At this time, the transmission shaft 33 drives the sleeve 50 to rotate. The sleeve 50 drives the switching gear 48 to rotate through the lifting shaft 56. The switching gear 48 drives the inner gear 47 to rotate. When gear 47 rotates, the internal gear 47 drives the gear ring 45 to rotate in the opposite direction. The gear ring 45 drives the turntable 43 to rotate in the opposite direction through the L-shaped connecting shaft 44. The turntable 43 drives the actuating shaft 42 to drive the actuating plate 41 to rotate in the opposite direction. The actuating plate 41 can then move the New Year's buns on the elastic plate 8 to the conveyor belt on the other side for transport. This allows for the classification and sampling of New Year's buns based on their integrity, avoiding the occurrence of incomplete New Year's buns during sampling and testing. The results of the sampling and testing of New Year's buns are more accurate and representative.
