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 formula food, is a formula food designed for people with restricted food intake, digestion 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 crucial to test the powder state during production. The automatic detection and conveying device for FSMP can accurately convey the FSMP powder to the detection area, improving the detection efficiency, ensuring the stable quality of FSMP during the production process, and providing 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 charging 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 charging 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 feeding and sampling and testing 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, this 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, thereby seriously affecting 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 food to meet the actual needs of the existing technology for testing powder, where powder is difficult to be discharged due to surface tension, resulting in low detection efficiency and affecting the accuracy of detection results.

Grooves are provided on both sides of the inner wall of the fixed seat, and one end of the protruding rod is in contact with the groove.

[0016] Beneficial effects of the present invention:

[0017] 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, when the connecting rod rises, the roller will rotate by the action of the spiral groove. 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.

[0018] When the turntable of this 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 return spring at the bottom of the card 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. The other end of the pull rope is connected to the coil spring inside the second connecting cylinder, so when the winding roller rotates, the coil spring will move, and the other end of the winding roller is connected to the ratchet disk, so the ratchet disk will rotate. Since the winding roller rotates, the ratchet disk rotates forward when the coil 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 drive the test tube to shake. When the turntable rotates 180 degrees, it is necessary to pull the pull rod 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, since there is no external force restriction, 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.

[0019] In this automatic detection and conveying device for special medical food, since the inner part of the limiting sleeve 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, thereby allowing the powder entering the interior of the test tube to dissolve quickly. Through this structural design, the detection test tube is automatically shaken without manual shaking, thereby greatly improving the detection efficiency.

[0020] When the automatic detection and conveying device for special medical food rotates the rotating rod through the handwheel at the upper end of the rotating rod, an obvious resistance will be generated every 180 degrees of rotation, which makes it convenient for the user to rotate it to a specific angle, 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.

[0034] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0036] 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 fixing seat 9 is fixedly connected to the middle part of the upper end surface of the base 1, and a rotating rod 5 is connected to the internal engagement and rotation of the fixing seat 9, one side of the upper end of the bracket 2 is fixedly connected to a connecting seat 21, and the upper end of the connecting seat 21 is rotatably connected to a roller 44, a buffer spring 23 is fixedly connected to one side 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 member for rotating the roller 44. The rotation causes the ball head 22 to strike the storage tank 3 to vibrate the control component, the base 1 is internally engaged and rotatably connected to the first drive rod 26, the internal 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, and one side of the lower end of the first drive rod 26 is connected to the second drive rod 29 through a bevel gear set, and a placement rack 8 is fixedly connected to one side of the middle of the upper end surface of the base 1, and 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, and 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 The fourth driving rod 33 on the base 1, 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 provided between the second driving rod 29 and the third driving rod 31. 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, thereby causing it 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, and provide accurate results for subsequent testing. Accurate sample, secondly, the device includes a detection test tube 35 and a shaking component. The detection test tube 35 is used to hold the special medical food powder sample taken out from the storage tank 3, and the shaking component is driven by the fourth drive rod 33, the third drive rod 31 and the power storage component to rotate the detection test tube 35, thereby shaking the powder sample in the test tube. This shaking operation can fully mix the powder sample and make the test result more accurate. In addition, the power storage component can store the force generated when the turntable 4 transports the metering cylinder 7 and release it at the appropriate time, drive the third drive rod 31 to rotate, and drive the shaking component to work. This design not only improves the energy utilization efficiency, but also makes the operation of the entire device more stable and efficient.

[0037] 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 on the side close to 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 respectively fixedly connected to both 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 one hundred and eighty 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. As the card plate 16 moves upward, it drives the connecting rod 17 to rise. 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 accurate samples for subsequent testing.

[0038] 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, the inner rotation of the first connecting cylinder 30 is connected to a winding roller 43, the outer wall of the winding roller 43 is spirally wound with a pull rope 39, one end of the pull rope 39 passes through the fixing plate 37 and is fixedly connected to the coil spring 38, 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 assembly 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 internally clamped with a ratchet 42. 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 card plate 16. The function of the first drive rod 26 is to slide and engage with the first drive rod 26. When the turntable 4 rotates, the first drive rod 26 rotates synchronously through the action of the spline shaft 18. The rotation of the first drive rod 26 can drive the winding roller 43 inside the first connecting cylinder 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 cylinder 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, so the ratchet teeth 42 will not be used to drive the connecting ring 41 to rotate. If it does not rotate, the third driving rod 31 will not be driven to rotate, so the shaking assembly will not drive 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 driving 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 driving rod 31 to rotate through the action of the internal ratchet teeth 42. The rotation of the third driving rod 31 can drive the shaking assembly to work.

[0039] 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. The limiting sleeve 34 is used to maintain the rotation stability of the detection test tube 35, and the fourth driving rod 33 is coaxial with the ball seat 36 when 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 tube 35 is automatically shaken without manual shaking, thereby greatly improving the detection efficiency.

[0040] 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. 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. The lower end of the quantitative cylinder 7 contacts the upper end surface of the discharge disk 6. One side of the lower end of the quantitative cylinder 7 is rotatably connected to the rotating plate 13. The middle part of the upper end surface of the rotating plate 13 is fixedly connected to the telescopic spring 14. The upper end of the telescopic spring 14 is fixedly connected to the inner wall of the quantitative cylinder 7. The lower end surface of the discharge disk 6 is fixedly connected to the side away from the bracket 2 with a conical cylinder 11. 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, after the metering cylinder 7 on one side is filled with the special medical food powder, the rotating rod 5 is rotated. After the rotating rod 5 rotates one hundred and eighty degrees, the metering 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 metering cylinder 7 is rotated by the action of the telescopic spring 14. The dust inside the metering 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.

[0041] 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 a connecting spring 28 on both sides. The connecting spring 28 is fixedly connected to a protruding rod 24 at one end away from the rotating rod 5. A groove 27 is provided on both sides of the inner wall of the fixed seat 9. One end of the protruding rod 24 contacts the groove 27. The protruding rod 24 is connected to the lower end of the rotating rod 5 through the connecting spring 28. The protruding rod 24 is engaged in the groove 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, which makes it convenient for the user to rotate to a specific angle, 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.
