Description

Technical Field

[0001] The present invention relates to the technical field of detection and conveying devices, and in particular to an automatic detection and conveying device for special medical food. Background Art

[0002] FSMP, whose full name is FSMP, is a formula food specially designed for people with restricted food intake, digestive and absorption disorders, metabolic disorders or specific disease states. During the production process, FSMP usually exists in powder form, and its quality is directly related to the patient's health and treatment effect. In order to ensure the safety and effectiveness of FSMP, it is very important to detect the powder state during production. The automatic detection and conveying device for FSMP can accurately convey the FSMP powder to the detection area, which improves the detection efficiency, ensures the stable quality of FSMP during the production process, and provides patients with safer and more reliable nutritional support.

[0003] In the prior art, a Chinese patent document with publication number CN218877640U proposes a powder coating loading and transmission device, including a roller conveyor, a feeding mechanism, a loading box limiting device, a weighing device, an electric control box, and a box pushing device; the roller conveyor is divided into a first conveyor belt and a second conveyor belt; the loading box limiting device includes two limiting rods and a connecting rod; the box pushing device includes a first cylinder and a box pushing plate. Although the application has a simple structure and can automatically complete quantitative feeding, it can also reduce powder dust during the loading and sampling detection process according to the particularity of coating powder packaging, reduce the amount of powder floating in the air, and improve production and packaging safety. However, the technology is consistent with the traditional method in that due to the inherent surface tension of the powder, if there is no external force intervention, it is very easy to form adhesion on the inner wall of the storage tank, resulting in difficulty in feeding. This adhesion phenomenon not only hinders the normal falling of the powder, but also makes quantitative transmission impossible, which in turn has a serious impact on the accuracy of powder detection and may cause a series of quality control problems.

[0004] Furthermore, we disclose an automatic detection and conveying device for special medical foods to meet the actual needs of the existing technology for detecting powders, where powders are difficult to be discharged due to surface tension, resulting in low detection efficiency and affecting the accuracy of detection results.

[0015] Preferably, the inner lower end of the rotating rod is located in a fixed seat and both sides thereof are fixedly connected with connecting springs, one end of the connecting spring away from the rotating rod is fixedly connected with a convex rod, and grooves are provided on both sides of the inner wall of the fixed seat, and one end of the convex rod is in contact with the groove.

[0016] Beneficial effects of the present invention: When the turntable of the automatic detection and conveying device for special medical food rotates 180 degrees so that the metering cylinder is placed at the lower end of the storage tank, the pull rod pulls the card plate upward, and the card plate drives the connecting rod to rise while moving upward. Since one end of the connecting rod is slidably connected to the inside of the spiral groove on the roller, the roller will rotate by itself through the action of the spiral groove when the connecting rod rises. When the roller rotates, it can drive the buffer spring and the ball head to rotate. After rotating to a certain angle, the ball head will collide with the storage tank, causing the storage tank to vibrate. This design can effectively prevent the special medical food powder from being unable to be discharged in the storage tank due to surface tension, ensure the fluidity and uniformity of the powder, thereby ensuring that the metering cylinder can be filled with powder and quantitative transmission can be ensured, providing accurate samples for subsequent detection and improving detection efficiency.

[0017] When the turntable of the automatic detection and conveying device for special medical food needs to rotate to convey materials, the lower end of the spline shaft inside the rotating rod is slidably engaged with the first driving rod through the action of the reset spring at the bottom of the clamping plate. When the turntable rotates, the first driving rod rotates synchronously through the action of the spline shaft. The rotation of the first driving rod can drive the winding roller inside the first connecting cylinder to rotate, so that the pull rope is wound around the surface of the winding roller, and the other end of the pull rope is connected to the winding spring inside the second connecting cylinder. Therefore, when the winding roller rotates, the winding spring will move. The other end of the winding roller is connected to a ratchet disk, so the ratchet disk will rotate. Since the winding roller rotates, the ratchet disk rotates forward when the winding spring moves. The ratchet will not be used to drive the connecting ring to rotate, and the connecting ring will not drive the third driving rod to rotate if it does not rotate. Therefore, the shaking assembly will not cause the test tube to shake. When the turntable rotates 180 degrees, the pull rod needs to be pulled to knock the storage tank, so the spline shaft can be driven to rise through the clamping plate. When the lower end of the spline shaft is disengaged from the sliding engagement with the first driving rod, there is no external force restriction, so the coil spring will move in the opposite direction compared with before, driving the winding roller to rotate in the opposite direction compared with before. At this time, the ratchet disk reverses and can drive the third driving rod to rotate through the action of the internal ratchet. The rotation of the third driving rod can drive the shaking assembly to work.

[0018] Since the interior of the limiting sleeve of the automatic detection and conveying device for special medical food contacts the lower end of the detection test tube, and the middle part of the test tube is mounted on the ball seat on the placement rack, the fourth driving rod drives the detection test tube to rotate along the middle part of the ball seat, so that the powder entering the test tube is quickly dissolved. Through this structural design, the detection test tube is automatically shaken without manual shaking, thereby greatly improving the detection efficiency.

[0019] When the automatic detection and conveying device for special medical food rotates the rotating rod through the hand wheel at the upper end of the rotating rod, an obvious resistance will be generated every 180 degrees of rotation, so that the user can rotate it to a specific angle conveniently, so that the metering cylinder can be accurately placed at the lower end of the storage tank for feeding or at the upper end of the conical cylinder for discharging.

[0025] like Figures 1 to 10As shown, an automatic detection and conveying device for special medical food comprises a base 1 and a bracket 2 installed on one side of the middle part of the upper end surface of the base 1, one side of the upper end surface of the bracket 2 is fixedly connected to a storage tank 3 for storing special medical food powder, a fixed seat 9 is fixedly connected to the middle part of the upper end surface of the base 1, and a rotating rod 5 is rotatably connected to the inside of the fixed seat 9, a connecting seat 21 is fixedly connected to one side of the upper end of the bracket 2, and a roller 44 is rotatably connected to the upper end of the connecting seat 21, a buffer spring 23 is fixedly connected to one side of the upper end of the outer wall of the roller 44, and a ball head 22 is fixedly connected to the end of the buffer spring 23 away from the roller 44, and a spline shaft 18 is slidably connected to the inside of the rotating rod 5, and the upper end of the spline shaft 18 passes through the rotating rod 5 and is provided with a roller 44. The control component rotates so that the ball head 22 knocks the storage tank 3 to make it vibrate. The base 1 is internally engaged and rotatably connected with a first drive rod 26. The upper end of the first drive rod 26 is provided with a spline hole 25. The lower end of the spline shaft 18 is slidably engaged and connected in the spline hole 25. One side of the lower end of the first drive rod 26 is connected to a second drive rod 29 through a bevel gear set. A placement rack 8 is fixedly connected to one side of the middle part of the upper end surface of the base 1. A ball seat 36 is provided at one end of the placement rack 8. A detection test tube 35 for detecting special medical food powder is penetrated and sleeved in the inner middle part of the ball seat 36. A shaking component for rotating the detection test tube 35 is provided at the lower end of the detection test tube 35. The shaking component includes a locking and rotatably connected to A fourth driving rod 33 on the base 1, one side of the lower end of the fourth driving rod 33 is connected to the third driving rod 31 through a bevel gear set, and a power storage component is arranged between the second driving rod 29 and the third driving rod 31, and the power storage component is used to store the force generated by the rotation of the second driving rod 29 and drive the shaking component to work. The device includes a storage tank 3 for storing special medical food powder. Through the design of the rotating rod 5, the spline shaft 18 and the control component, the ball head 22 on the roller 44 can knock the storage tank 3 to make it vibrate. This design can effectively prevent the special medical food powder from being unable to be discharged in the storage tank 3 due to surface tension, ensure the fluidity and uniformity of the powder, and provide accurate results for subsequent detection. The device can obtain the correct sample. Secondly, the device includes a test tube 35 and a shaking assembly. The test tube 35 is used to hold the special medical food powder sample taken out from the storage tank 3, and the shaking assembly is driven by the fourth driving rod 33, the third driving rod 31 and the power storage assembly to rotate the test tube 35, thereby shaking the powder sample in the test tube. This shaking operation can fully mix the powder sample to make the test result more accurate. In addition, the power storage assembly can store the force generated when the turntable 4 transports the quantitative cylinder 7 and release it at an appropriate time, drive the third driving rod 31 to rotate, and drive the shaking assembly to work. This design not only improves the energy utilization efficiency, but also makes the operation of the entire device more stable and efficient.

[0026] Further, such as Figure 4As shown, the control component includes a card plate 16 fixedly connected to the upper end of the spline shaft 18, and the middle part of the upper end of the card plate 16 is rotatably connected to the pull rod 15, and the outer wall of the pull rod 15 is fixedly connected to the side of the roller 44. The outer wall of the roller 44 near the connecting rod 17 is provided with a spiral groove 20, and the end of the connecting rod 17 away from the pull rod 15 is slidably connected to the inside of the spiral groove 20. The control component also includes two return springs 19, which are fixedly connected to the two sides of the lower end surface of the card plate 16, and the lower ends of the two return springs 19 are fixedly connected to the rotating rod 5. When the turntable 4 rotates 180 degrees so that the metering cylinder 7 is placed at the lower end of the storage tank 3, the card plate 16 is pulled upward by the pull rod 15. The card plate 16 drives the connecting rod 17 to rise while moving upward. Since one end of the connecting rod 17 is slidably connected to the inside of the spiral groove 20 on the roller 44, when the connecting rod 17 rises, the roller 44 will rotate due to the action of the spiral groove 20. When the roller 44 rotates, it can drive the buffer spring 23 and the ball head 22 to rotate. After rotating to a certain angle, the ball head 22 will collide with the storage tank 3, causing the storage tank 3 to vibrate. This design can effectively prevent the special medical food powder from being unable to be discharged in the storage tank 3 due to surface tension, ensure the fluidity and uniformity of the powder, thereby ensuring that the metering cylinder 7 can be filled with powder, ensuring that quantitative transmission can be achieved, and providing an accurate sample for subsequent testing.

[0027] Further, such as Figures 8 to 10As shown, the power storage assembly includes a first connecting cylinder 30 and a second connecting cylinder 32, the first connecting cylinder 30 and the second connecting cylinder 32 are fixedly connected to the lower end surface of the base 1 through a connecting plate, a fixing plate 37 is fixedly connected between the first connecting cylinder 30 and the second connecting cylinder 32, a coil spring 38 is fixedly connected to the inner center of the second connecting cylinder 32, a winding roller 43 is rotatably connected to the inside of the first connecting cylinder 30, a pull rope 39 is spirally wound on the outer wall of the winding roller 43, one end of the pull rope 39 passes through the fixing plate 37 and is fixedly connected to the coil spring 38, and the end of the pull rope 39 away from the coil spring 38 is fixedly connected to the winding roller 43, and one end of the second driving rod 29 extends into the interior of the first connecting cylinder 30 and is connected to the winding roller 4 3 is fixedly connected, the power storage component also includes a ratchet disc 40 fixedly connected to the side of the winding roller 43 away from the second driving rod 29, the ratchet disc 40 is clamped with a ratchet 42 inside, the lower end of the ratchet 42 is rotatably connected to a connecting ring 41 through a connecting shaft, the outer side of the end surface of the connecting ring 41 close to the winding roller 43 is fixedly connected to a limit spring 45 through a connecting shaft, the upper end of the limit spring 45 is fixedly connected to the lower end surface of the ratchet 42, one end of the third driving rod 31 extends into the interior of the first connecting cylinder 30 and is fixedly connected to the end surface of the connecting ring 41 away from the winding roller 43. When the turntable 4 needs to rotate to convey materials, the lower end of the spline shaft 18 inside the rotating rod 5 is reset by the bottom return spring 19 of the clamping plate 16. The function is to slide and engage with the first driving rod 26. When the turntable 4 rotates, the first driving rod 26 rotates synchronously through the action of the spline shaft 18. The rotation of the first driving rod 26 can drive the winding roller 43 inside the first connecting tube 30 to rotate, so that the pull rope 39 is wound around the surface of the winding roller 43. The other end of the pull rope 39 is connected to the coil spring 38 inside the second connecting tube 32. Therefore, when the winding roller 43 rotates, the coil spring 38 will move. The other end of the winding roller 43 is connected to the ratchet disk 40, so the ratchet disk 40 will rotate. Since the winding roller 43 rotates, the ratchet disk 40 rotates forward when the coil spring 38 moves, the ratchet disk 40 will not use the ratchet teeth 42 to drive the connecting ring 41 to rotate. If it does not rotate, the third drive rod 31 will not be driven to rotate, so the shaking assembly will not cause the test tube 35 to shake. After the turntable 4 rotates one hundred and eighty degrees, since it is necessary to pull the pull rod 15 to knock the storage tank 3, the spline shaft 18 can be driven to rise through the clamping plate 16. When the lower end of the spline shaft 18 is disengaged from the sliding engagement with the first drive rod 26, since there is no external force restriction, the coil spring 38 will move in the opposite direction compared with before, driving the winding roller 43 to rotate in the opposite direction compared with before. At this time, the ratchet disk 40 reverses and can drive the third drive rod 31 to rotate through the action of the internal ratchet teeth 42. The rotation of the third drive rod 31 can drive the shaking assembly to work.

[0028] Further, such as Figure 7As shown, the shaking assembly also includes a limiting sleeve 34 fixedly connected to one side of the upper end of the fourth driving rod 33, and the lower end of the detection test tube 35 is sleeved inside the limiting sleeve 34, and the limiting sleeve 34 is used to maintain the rotation stability of the detection test tube 35. The fourth driving rod 33 is coaxial with the ball seat 36 when it is parallel to the base 1. When the fourth driving rod 33 on the shaking assembly is driven to rotate by the third driving rod 31, the fourth driving rod 33 can rotate with the limiting sleeve 34. Since the interior of the limiting sleeve 34 contacts the lower end of the detection test tube 35, and the middle part of the test tube is sleeved on the ball seat 36 on the placement rack 8, the fourth driving rod 33 will drive the detection test tube 35 to rotate along the middle part of the ball seat 36, so that the powder entering the test tube is quickly dissolved. Through this structural design, the detection test tube 35 is automatically shaken without manual shaking, thereby greatly improving the detection efficiency.

[0029] Further, such as Figures 1 to 3 As shown, the upper end of the outer wall of the rotating rod 5 is fixedly connected to the rotating disk 4 through a cross, the radius of the rotating disk 4 is equal to the distance from the center of the rotating rod 5 to the center of the discharge port at the lower end of the storage tank 3, and both ends of the rotating disk 4 are fixedly connected to the quantitative cylinder 7. The upper end of the base 1 is fixedly connected to the discharge disk 6 coaxial with the rotating disk 4 through a connecting plate, and the lower end of the quantitative cylinder 7 is in contact with the upper end surface of the discharge disk 6. A rotating plate 13 is rotatably connected to one side of the lower end of the quantitative cylinder 7. A telescopic spring 14 is fixedly connected to the middle part of the upper end surface of the rotating plate 13. The upper end of the telescopic spring 14 is fixedly connected to the inner wall of the quantitative cylinder 7. A conical cylinder 11 is fixedly connected to the side of the lower end surface of the discharge disk 6 away from the bracket 2. A rounded corner 10 is provided on one side of the inner wall of the conical cylinder 11, and a telescopic cylinder 12 is fixedly connected to the lower end of the conical cylinder 11. When the conveying device is in use, when one side of the quantitative cylinder 7 is filled with the special medical food powder, the rotating rod 5 is rotated. After the rotating rod 5 rotates 180 degrees, the quantitative cylinder 7 filled with the special medical food powder will move to the upper end of the conical cylinder 11, and the rotating plate 13 at the lower end of the quantitative cylinder 7 is rotated by the action of the telescopic spring 14. The dust inside the quantitative cylinder 7 is discharged into the conical cylinder 11 through the rectangular groove, and finally falls into the inside of the detection test tube 35 through the telescopic cylinder 12. The setting of the telescopic cylinder 12 makes it difficult for the dust to float and diffuse in the air during the falling process.

[0030] Further, such as Figure 5As shown, the inner lower end of the rotating rod 5 is located in the fixed seat 9 and is fixedly connected to connecting springs 28 on both sides. The end of the connecting spring 28 away from the rotating rod 5 is fixedly connected to a convex rod 24. Grooves 27 are provided on both sides of the inner wall of the fixed seat 9. One end of the convex rod 24 contacts the groove 27. The convex rods 24 are connected to the lower ends of the rotating rod 5 through the connecting springs 28. The convex rods 24 are engaged in the grooves 27, so that when the conveying device is in use, when the rotating rod 5 is rotated, an obvious resistance will be generated every one hundred and eighty degrees of rotation, so that the user can rotate to a specific angle conveniently, so that the metering cylinder 7 can be accurately placed at the lower end of the storage tank 3 for feeding or at the upper end of the conical cylinder 11 for discharging.
