Description

Technical Field

[0001] This invention relates to powder conveying technology, and more particularly to a benzoic acid powder conveying device for use in production workshops. Background Technology

[0002] Tranexamic acid is a hemostatic drug, with tranexamic acid as its main component. Its hemostatic mechanism works by preventing the normal function of a blood clot-dissolving enzyme (fibrinolytic enzyme), thus protecting the blood clot at the wound site from being destroyed.

[0003] Due to its chemical properties, tranexamic acid needs to be stored in a sealed container to avoid light and humidity. Therefore, tranexamic acid powder needs to be dried during production. However, the dried powder is also susceptible to clumping due to moisture in the air during transportation and packaging. Thus, it needs to be protected again during transportation and packaging to prevent it from being affected by external air moisture before packaging, which would shorten its shelf life.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] like Figures 1 to 18As shown, this invention relates to a tranexamic acid powder conveying device for a production workshop, comprising a workbench 1, a drying chamber 2, a conveyor belt 3, an adjusting assembly 4, and a supporting assembly 5. The drying chamber 2 is mounted on the workbench 1 via the supporting assembly 5, which adjusts the height between the drying chamber 2 and the supporting assembly 5 to accommodate the conveyor belt 3. The adjusting assembly 4 is mounted on the drying chamber 2 and passes through it, allowing an adjusting rod 6 to extend onto the conveyor belt 3 to disperse the tranexamic acid powder on the conveyor belt 3. Since the position of the adjusting rod 6 can rotate with the rotating component 7, the rotating component 7 can be rotated according to different needs, keeping the adjusting rod 6 rotating with it. Alternatively, an adjusting plate 8 can drive a movable component 9 and the adjusting rod 6 to rotate on the rotating component 7, causing the adjusting rod 6 to rotate and hinge within the through hole 10, moving it to different positions on the conveyor belt 3.

[0020] When pressure is required to limit the corresponding movement of the arc surface 11 and the arc groove 12, the rotating component 7 and the adjusting plate 8 can be rotated simultaneously. This allows the rotating component 7 and the adjusting plate 8 to rotate independently, or the adjusting plate 8 and the rotating component 7 to rotate together. The workbench 1 has multiple support legs 13 at its lower end. The drying chamber 2 is set on the workbench 1. The drying chamber 2 has a central conveying area 14 and an airflow cavity 15 inside. The upper end of the drying chamber 2 has symmetrically arranged connecting pipes 16, which are used to connect to the drying equipment. The drying equipment can generate dry and warm airflow, which enters the drying chamber 2 through the connecting pipes 16. The dry and warm airflow fills the drying chamber 2, causing the drying chamber 2 to heat up, and the temperature in the central conveying area 14 of the drying chamber 2 also rises accordingly.

[0021] Meanwhile, since the connecting pipe 16 is located at the top of the drying chamber 2, the conveyor belt 3 is positioned at the bottom of the conveying area 14 in the middle of the drying chamber 2. This ensures that the upper part of the conveying area 14 can be heated. The gas entering from the connecting pipe 16 will first heat the upper part of the conveying area 14, so it is necessary to maintain some space between the conveyor belt 3 and the upper part of the conveying area 14. This space helps to prevent a large temperature from directly affecting the tranexamic acid powder, and also allows for a large amount of space at the top of the conveyor belt 3, enabling the tranexamic acid powder accumulated on the conveyor belt 3 to form a cone-shaped accumulation.

[0022] Since tranexamic acid powder is stacked in a cone shape, an adjusting rod 6 is needed to disperse the tranexamic acid powder at different positions, thereby keeping the powder dispersed. This ensures that the cone-shaped tranexamic acid powder accumulated from the discharge point can be pushed apart and will not continue to maintain its cone shape. This ensures that the powder inside the drying chamber 2 is dried together when passing through the drying chamber 2, effectively improving the moisture-proof performance of the tranexamic acid powder during the transfer process.

[0023] The conveyor belt 3 is positioned between the workbench 1 and the drying chamber 2. The conveyor belt 3 passes through the conveying area 14, and the temperature provided by the drying chamber 2 keeps the tranexamic acid powder on the conveyor belt 3 warm and moisture-proof. The bottom of the conveying area 14 is provided with an arc-shaped surface 17 that cooperates with the conveyor belt 3, keeping the conveyor belt 3 in contact with the arc-shaped surface 17, so that the upper half 18 of the conveyor belt 3 is in an arc shape, which facilitates the tranexamic acid powder to move towards the middle of the conveyor belt 3.

[0024] As is known from existing technology, the conveyor belt 3 is generally in the shape of a circular racetrack. When in use, the conveyor belt 3 is maintained with an upper half 18 and a lower half 19, with both ends supported by a transmission roller in the middle, and a motor drive can be installed on one of the transmission rollers.

[0025] The lower end of the drying chamber 2 is provided with symmetrically arranged exhaust pipes 20. The exhaust pipes 20 are used to discharge the gas inside the drying chamber 2. The discharged gas can act on the lower half 19 of the conveyor belt 3. The discharged gas preheats or maintains the temperature of the lower half 19 of the conveyor belt 3, thereby avoiding the temperature drop of the lower half 19 of the conveyor belt 3 due to weather conditions or the length of the conveyor belt 3. This allows the aminobenzoic acid powder on the conveyor belt 3 to maintain the corresponding temperature for a longer period of time, saving time and reducing energy consumption, thus improving the conveying efficiency of aminobenzoic acid powder.

[0026] The lower end of the drying oven 2 is provided with symmetrical slide rails 21 on both sides. A through area 22 is formed in the middle of the slide rail 21, and elastic plates 23 are formed on both sides of the slide rail 21. The lower end of the elastic plate 23 is provided with a horizontal section 24 and a vertical section 25 extending into the through area 22. The first limiting end 26 and the second limiting end 27 are placed on the vertical section 25.

[0027] When the elastic plate 23 is subjected to external force, it can deform. Therefore, when installing the support member 28, the side plate 29 of the support member 28 can be rotated 90° first. The width between the side plates 29 is less than the width between the transverse sections 24, keeping the side plates 29 of the entire support member 28 parallel to the direction of the slide rail 21. After the slide rail 21 is placed on the support member 28, the support member 28 is rotated. During the rotation, the support member 28 can push the elastic plate 23. After the side plates 29 on the support member 28 are perpendicular to the direction of the slide rail 21, the first limiting end 26 and the second limiting end 27 are placed in different vertical sections 25, and the contact surface 30 supports the slide rail 21, thus ensuring the position of the drying chamber 2. Finally, the bearing member 31 and the pressure member 32 can be rotated to ensure that the drying chamber 2 is in a horizontal state, keeping the position of the drying chamber 2 horizontal.

[0028] The adjusting component 4 is installed on the drying chamber 2. The adjusting component 4 has multiple locations. The drying chamber 2 has through holes 10 that cooperate with the adjusting component 4. The through holes 10 are used for the adjusting rod 6 to rotate in the through holes, so that the adjusting rod 6 can stay in the area between the middle and the edge of the conveyor belt 3. In conjunction with the multiple adjusting rods 6, the aminobenzoic acid powder on the conveyor belt 3 is dispersed to keep it evenly heated and dried.

[0029] The adjustment assembly 4 includes a rotating component 7, an adjustment plate 8, an adjustment rod 6, an adjustment component 33, and symmetrically arranged movable components 9. The rotating component 7 passes through the adjustment plate 8 and is installed on the drying oven 2. The adjustment plate 8 is restricted to the middle position of the rotating component 7 by the movable component 9. The movable component 9 is located at both ends of the rotating component 7 and its lower end is inserted into the adjustment plate 8. The adjustment component 33 is hinged to the upper end of the movable component 9 by the hinge rod 34 and is located at the upper end of the rotating component 7.

[0030] The rotating component 7 consists of a support plate 35, a rod 36, and symmetrically arranged elastic arms 37. The support plate 35 is located at the upper end of the rod 36. A first compression gap 38 is formed between the elastic arms 37. The lower end of the elastic arm 37 is provided with a guide buckle 39. The drying oven 2 is provided with an insertion hole 40 that matches the diameter of the elastic arm 37.

[0031] A first spring 41 is provided at the lower end of the rod 36. The first spring 41 is sleeved on the elastic arm 37. When the rotating part 7 is inserted into the insertion hole 40, the lower end of the first spring 41 is kept on the drying box 2 and the first spring 41 is compressed. At this time, the first spring 41 is in a state that cannot be compressed or is slightly compressed, thereby ensuring that the rotating part 7 cannot be pushed down further. The rod 36 and the elastic arm 37 form two blocking surfaces 42, and the upper end of the first spring 41 contacts the blocking surface 42.

[0032] During installation, the rotating component 7 can be simply inserted by aligning the guide buckle 39 on the elastic arm 37 with the insertion hole 40. The guide buckle 39 has a guide arc surface 43 and a retaining surface 44. The retaining surface 44 contacts the upper inner wall of the cavity 15, and in conjunction with the elastic force of the first spring 41, the rotating component 7 is kept from easily rotating.

[0033] When the rotating component 7 is not inserted into the insertion hole 40, the lower end of the first spring 41 is held on the retaining surface 44, which supports the first spring 41, preventing it from detaching from the rotating component 7. During installation, the elastic arm 37 is guided by the guiding arc surface 43, causing it to move towards the first compression gap 38, thus allowing the guide buckle 39 to pass through the insertion hole 40 and enter the cavity 15. This causes the guide buckle 39 to also move towards the center. However, since the diameter of the first spring 41 is larger than the diameter of the insertion hole 40, the first spring 41 will not be placed inside the insertion hole 40. Instead, it will be placed on the surface of the drying oven 2, where the drying oven 2 supports the rotation and compresses the first spring 41. Therefore, the rotating component 7 requires force to rotate; without external force or with a small force, it cannot maintain its rotation.

[0034] When the adjusting plate 8 and the rotating part 7 need to rotate together, a limiting protrusion can be provided in the positioning hole 45, and a limiting recess can be provided on the rod body 36 of the rotating part 7, so that the adjusting plate 8 can slide up and down on the rod body 36, but the adjusting plate 8 cannot be kept to rotate alone.

[0035] Alternatively, extensions can be provided at both ends of the second spring 46, which are then inserted into the support plate 35 and the adjusting plate 8, respectively. This allows the adjusting rod 6 to rotate slightly when blocked by the tranexamic acid powder, thereby resetting via the second spring 46 and maintaining the adjusting rod 6 in a slightly oscillating state, which better disperses the tranexamic acid powder. The friction between the holding surface 44 and the upper inner wall of the cavity 15 is greater than the oscillation resistance experienced by the adjusting rod 6, thus preventing the rotating component 7 from rotating.

[0036] The movable component 9 is provided with a plate 47, a bent plate 48, and a hinge plate 49. The bent plate 48 is placed on the support plate 35, and the hinge plate 49 is provided with a hinge hole 50 that mates with the hinge rod 34. Symmetrically arranged elastic extensions 51 are formed at the lower end of the plate 47, and a second compression gap 52 is formed between the elastic extensions 51. The elastic extensions 51 are provided with a notch 53 and a guide slope 54.

[0037] The adjusting plate 8 is provided with a positioning hole 45 that mates with the rod 36, a fixing hole 55 that mates with the adjusting rod 6, and an insertion groove 56 that mates with the movable part 9. The insertion groove 56 is provided with a guide slope 57 that mates with the guide slope 54. A second spring 46 is sleeved on the rod 36. The upper end of the second spring 46 contacts the support plate 35, and the lower end is placed on the adjusting rod 6.

[0038] During installation, the movable part 9 is inserted into the insertion slot 56 by the cooperation of the guide ramp 57 and the guide ramp 54. The length of the insertion slot 56 matches the distance between the vertical surface 58 in the notch 53, so the insertion slot 56 and the notch 53 cooperate to keep the adjusting plate 8 on the movable part 9, and the position can be moved up and down with the movable part 9.

[0039] The adjusting component 33 consists of a handle 59 and a rotating end 60. The rotating end 60 is hinged to the hinge plate 49 via a hinge rod 34. The rotating end 60 is provided with a first pressure surface 61, a second pressure surface 62, and a pressure arc surface 11. The support plate 35 is provided with an arc-shaped groove 12 that mates with the pressure arc surface 11. The distance between the first pressure surface 61 and the hinge rod 34 is H1, the distance between the second pressure surface 62 and the hinge rod 34 is H2, and the distance between the pressure arc surface 11 and the hinge rod 34 is H3, where H1 < H2 < H3. When the pressure arc surface 11 is placed on the support plate 35, it can maintain the engagement and limiting of the pressure arc surface 11 and the arc-shaped groove 12.

[0040] Since the first spring 41 cannot be further compressed, the rotating member 7 will not move downwards and will remain stationary. Therefore, when the adjusting member 33 is rotated around the hinge rod 34, and because the distances between the first pressure surface 61, the second pressure surface 62, and the pressure arc surface 11 and the hinge rod 34 are different, the adjusting member 33 will remain acting on the support plate 35 when the adjusting member 33 is rotated. The hinge rod 34 will pull the movable member 9 and the adjusting plate 8 upwards and compress the second spring 46.

[0041] Depending on the position of the adjusting rod 6 on the conveyor belt 3, the first pressure surface 61, the second pressure surface 62, or the pressure arc surface 11 can be kept on the support plate 35. Since the upper part 18 of the conveyor belt 3 is arc-shaped, a height difference will occur between the middle and the edge of the conveyor belt 3. Therefore, when it is necessary to change the position of the adjusting rod 6, the adjusting component 33 needs to be rotated to keep the adjusting component 33 moving the position of the movable component 9, the adjusting plate 8, and the adjusting rod 6, so as to avoid direct contact between the adjusting rod 6 and the conveyor belt 3.

[0042] In addition, the lower end of the adjusting rod 6 can be set with different shapes to adapt to the spreading of aminotranexamic acid powder.

[0043] like Figure 18 As shown, the adjusting member 33 rotates around the hinge rod 34, that is, it rotates in the direction of F1. Since the position of the rotating member 7 is not fixed, the movable member 9 and the adjusting plate 8 are kept moving in the direction of F2.

[0044] Support assembly 5 is used to support drying chamber 2 and to adjust the height of the conveying area between drying chamber 2 and workbench 1. Support assembly 5 includes a fixing member 63, a support member 28, a limiting plate 64, a bearing member 31, and a pressure applying member 32. The support member 28, limiting plate 64, bearing member 31, and pressure applying member 32 are all mounted on the fixing member 63. The limiting plate 64 is located in the middle of the support member 28, and the pressure applying member 32 is located on the limiting plate 64. Rotating the pressure applying member 32 maintains the distance between the pressure applying member 32 and the bearing member 31, while rotating the bearing member 31 adjusts the height of the support member 28.

[0045] The fixing member 63 consists of a fixing seat 65 and a threaded rod 66. The fixing seat 65 is connected to the worktable 1. The bearing member 31 and the pressure member 32 are provided with a threaded hole 67 that mates with the threaded rod 66. The bearing member 31 and the pressure member 32 can be nuts. The limiting plate 64 is provided with a first mounting hole 68 that mates with the threaded rod 66.

[0046] The support member 28 consists of a base plate 69 and symmetrically arranged side plates 29, forming a receiving area 70 between the side plates 29 to accommodate the limiting plate 64 and the pressure member 32. The side plates 29 are provided with limiting holes 71 that mate with the limiting plate 64, and the height of the limiting holes 71 is greater than the thickness of the limiting plate 64. The base plate 69 is provided with a second mounting hole 72 that mates with the threaded rod 66.

[0047] The upper end of the side plate 29 is provided with a support portion 73, one end of which forms a first limiting end 26 and the other end forms a second limiting end 27. The support portion 73 is provided with a contact surface 30. The lower end of the second limiting end 27 is provided with a clearance opening 74 for avoiding the vertical section 25 and the horizontal section 24.

[0048] When adjusting the height of the drying oven 2, it is only necessary to change the position of the bearing member 31. When fixing the position of the support member 28, it is only necessary to rotate the pressure member 32 in conjunction with the bearing member 31, so that the limiting plate 64 acts on the support member 28, and the distance between the bearing member 31 and the pressure member 32 is tightened.

[0049] Of course, the drying oven 2 can also be slidably installed on the support 28 via the slide rail 21 during installation.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
