Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pharmaceutical screening technology, and in particular relates to a screening machine with an anti-clogging structure. Background Technology
[0002] Pharmaceutical raw material screening machines are specialized screening equipment used in pharmaceutical production. They can accurately classify pharmaceutical raw materials by particle size, ensuring the quality and consistency of the raw materials. These machines are typically characterized by high precision, high efficiency, ease of operation and maintenance, and can handle materials with different physical properties, such as dry powder, wet powder, and granules.
[0003] However, the above-mentioned device still has the following problems during implementation:
[0004] Existing technology makes the feed pipe of pharmaceutical raw material screening machine the most prone to clogging. When the feeding speed is too fast or the material is too wet or viscous, blockage may occur at the feed inlet. Therefore, a screening machine with an anti-clogging structure is proposed to solve the above problems. Utility Model Content
[0005] In view of the problems existing in the prior art, this utility model provides a screening machine with an anti-clogging structure, which has the advantage of anti-clogging and can overcome the above problems or at least partially solve the problem that the feed pipe of the pharmaceutical raw material screening machine is the most easily clogged area. When the feeding speed is too fast or the material is too wet or viscous, blockage may occur at the feed inlet.
[0006] This utility model is implemented as follows: a screening machine with an anti-clogging structure includes a drum screening device, a feeding pipe and an expansion pipe. The top of the drum screening device is fixedly connected to the bottom of the feeding pipe, and the top of the feeding pipe is fixedly connected to the bottom of the expansion pipe.
[0007] A fixing ring is fixedly connected to the surface of the feeding tube, and a hexagonal shell is fitted on the surface of the feeding tube. L-shaped rods are fixedly connected to the front and rear sides of the hexagonal shell, and the opposite sides of the two L-shaped rods are fixedly connected to the feeding tube.
[0008] The top of the feeding tube is equipped with a rotating component, and the inner cavity of the hexagonal shell is equipped with a striking component, and the number of striking components is six.
[0009] In a preferred embodiment of this invention, the rotating assembly includes a connecting plate. The bottom of the connecting plate is fixedly connected to the feed pipe, and a servo motor is fixedly connected to the top of the connecting plate. A gear is fixedly connected to the output end of the servo motor, and a gear ring is movably connected to the top of the fixed ring. The left side of the gear meshes with the gear ring. By setting the rotating assembly, when it is necessary to drive the gear ring to rotate, the servo motor is turned on to drive the gear at the output end to rotate. The rotation of the gear will drive the gear ring to rotate on the top of the fixed ring.
[0010] In a preferred embodiment of this invention, the top of the fixed ring is provided with a sliding groove, and a sliding ring is slidably connected to the inner cavity of the sliding groove. The top of the sliding ring is fixedly connected to the gear ring. By setting the sliding groove and the sliding ring, the sliding ring and the sliding groove can control the rotation position of the gear ring when it rotates, and can also reduce the friction between it and the fixed ring, so that no sound is generated when the gear rotates.
[0011] In a preferred embodiment of this invention, a matching plate is fixedly connected to the top of the toothed ring, and the matching plate matches the surface of the feed pipe and the expansion pipe. A dredging rod is fixedly connected to the right side of the matching plate, and there are multiple dredging rods. By setting the matching plate and the dredging rods, since the matching plate can match the surface of the expansion pipe and the fixed ring, the rotating matching plate can drive the dredging rods to completely dredge the feed pipe.
[0012] As a preferred embodiment of this utility model, a trapezoidal block is fixedly connected to the left side of the matching plate, and an extrusion block that works in conjunction with the trapezoidal block is movably connected to the surface of the feeding tube. There are six extrusion blocks. By setting the trapezoidal block and the extrusion block, the matching plate can drive the trapezoidal block to extrude the extrusion block when it rotates. The resulting extrusion force will prevent the extrusion block from contacting the feeding tube, while the extrusion block can strike the feeding tube.
[0013] In a preferred embodiment of this invention, the striking assembly includes a stroke rod, a connecting ring, and a spring. The stroke rod is movably connected to the inner cavity of the hexagonal shell. The side of the stroke rod near the extrusion block penetrates the hexagonal shell and is fixedly connected to the extrusion block. The connecting ring is fixedly connected to the surface of the stroke rod. The spring is sleeved on the surface of the stroke rod, and the side of the spring near the connecting ring is fixedly connected to the connecting ring. By setting the striking assembly, when the extrusion block separates from the trapezoidal block, the spring undergoes elastic deformation, which drives the stroke rod back to its original position. The movement of the stroke rod causes the extrusion block to strike the feed pipe, and the vibration force of the extrusion block when striking can also play a role in unblocking.
[0014] As a preferred embodiment of this utility model, a stroke tube is sleeved on the surface of the stroke rod. The side of the stroke tube closest to the inner wall of the hexagonal shell is fixedly connected to the inner wall of the hexagonal shell. By setting the stroke tube, when the extrusion block drives the stroke rod and the connecting ring to move, the stroke tube can control the movement position of the stroke rod, so that the stroke rod will not move randomly when it moves.
[0015] This invention utilizes a combination of an expanding tube, a fixing ring, a hexagonal shell, an L-shaped rod, a rotating assembly, and a striking assembly. The movement of the stroke rod causes the extrusion block to strike the feed pipe, continuously feeding the raw pharmaceutical materials into the expanding tube. This prevents the raw pharmaceutical materials from clogging the feed pipe, while the vibration force from the extrusion block also helps to clear the blockage. This solves the problem that the feed pipe of the pharmaceutical raw material screening machine is the most prone to clogging, especially when the feeding speed is too fast or the material is too wet or viscous, which may cause blockage at the feed inlet.

[0021] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0023] like Figures 1 to 4As shown in the figure, the present invention provides a screening machine with an anti-clogging structure, including a drum screening device 1, a feeding pipe 2 and an expanding pipe 3. The top of the drum screening device 1 is fixedly connected to the bottom of the feeding pipe 2, and the top of the feeding pipe 2 is fixedly connected to the bottom of the expanding pipe 3.
[0024] A fixing ring 4 is fixedly connected to the surface of the feeding tube 2. A hexagonal shell 5 is sleeved on the surface of the feeding tube 2. L-shaped rods 6 are fixedly connected to the front and rear sides of the hexagonal shell 5. The opposite sides of the two L-shaped rods 6 are fixedly connected to the feeding tube 2.
[0025] The top of the feed tube 2 is equipped with a rotating component 7, and the inner cavity of the hexagonal shell 5 is equipped with a striking component 8, and the number of striking components 8 is six.
[0026] refer to Figure 2 The rotating assembly 7 includes a connecting plate 71, the bottom of which is fixedly connected to the feed tube 2, a servo motor 72 is fixedly connected to the top of the connecting plate 71, a gear 73 is fixedly connected to the output end of the servo motor 72, and a gear ring 74 is movably connected to the top of the fixed ring 4. The left side of the gear 73 is meshed with the gear ring 74.
[0027] The above solution is adopted: by setting the rotating component 7, when it is necessary to drive the gear ring 74 to rotate, the servo motor 72 is turned on to drive the gear 73 at the output end to rotate. The rotation of the gear 73 will drive the gear ring 74 to rotate on the top of the fixed ring 4.
[0028] refer to Figure 4 The top of the fixed ring 4 is provided with a sliding groove 9, and the inner cavity of the sliding groove 9 is slidably connected to a sliding ring 10. The top of the sliding ring 10 is fixedly connected to the toothed ring 74.
[0029] By adopting the above solution: by setting the sliding groove 9 and the sliding ring 10, when the gear ring 74 rotates, the sliding ring 10 and the sliding groove 9 can control the rotation position of the gear ring 74, and can reduce the friction between it and the fixed ring 4, so that the gear 73 will not produce noise when it rotates.
[0030] refer to Figure 3 The top of the toothed ring 74 is fixedly connected to a matching plate 11, and the matching plate 11 matches the surface of the feed pipe 2 and the expansion pipe 3. The right side of the matching plate 11 is fixedly connected to a dredging rod 12, and there are multiple dredging rods 12.
[0031] The above solution is adopted: by setting the matching plate 11 and the unblocking rod 12, since the matching plate 11 can match the surface of the expanding pipe 3 and the fixing ring 4, the rotating matching plate 11 can drive the unblocking rod 12 to completely unblock the inside of the discharge pipe 2.
[0032] refer to Figure 3 and Figure 4A trapezoidal block 13 is fixedly connected to the left side of the matching plate 11, and an extrusion block 14 that cooperates with the trapezoidal block 13 is movably connected to the surface of the feed pipe 2, and there are six extrusion blocks 14.
[0033] The above scheme is adopted: by setting trapezoidal block 13 and extrusion block 14, when the mating plate 11 rotates, it can drive trapezoidal block 13 to extrude extrusion block 14. The extrusion force generated will cause extrusion block 14 to not contact with the feed pipe 2, while extrusion block 14 can knock on feed pipe 2.
[0034] refer to Figure 3 The striking assembly 8 includes a stroke rod 81, a connecting ring 82, and a spring 83. The stroke rod 81 is movably connected to the inner cavity of the hexagonal shell 5. The side of the stroke rod 81 near the extrusion block 14 passes through the hexagonal shell 5 and is fixedly connected to the extrusion block 14. The connecting ring 82 is fixedly connected to the surface of the stroke rod 81. The spring 83 is sleeved on the surface of the stroke rod 81. The side of the spring 83 near the connecting ring 82 is fixedly connected to the connecting ring 82.
[0035] The above solution is adopted: by setting the striking component 8, when the extrusion block 14 is separated from the trapezoidal block 13, the spring 83 undergoes elastic deformation, which will drive the stroke rod 81 back to its original position. The movement of the stroke rod 81 will drive the extrusion block 14 to strike the feed pipe 2, and the vibration force when the extrusion block 14 strikes can also play a role in unblocking.
[0036] refer to Figure 3 The surface of the stroke rod 81 is fitted with a stroke tube 15, and the side of the stroke tube 15 near the inner wall of the hexagonal shell 5 is fixedly connected to the inner wall of the hexagonal shell 5.
[0037] The above solution is adopted: by setting the stroke tube 15, when the extrusion block 14 drives the stroke rod 81 and the connecting ring 82 to move, the stroke tube 15 can control the movement position of the stroke rod 81, so that the stroke rod 81 will not move randomly when it moves.
[0038] The working principle of this utility model:
[0039] In use, the servo motor 72 is turned on to drive the gear 73 at the output end to rotate. The rotation of the gear 73 will drive the gear ring 74 to rotate on the top of the fixed ring 4. When the gear ring 74 rotates, it will drive the anastomosis plate 11 to rotate around the surface of the feed tube 2 and the expansion tube 3. When the anastomosis plate 11 rotates, it will drive the unblocking rod 12 to rotate inside the feed tube 2. When the anastomosis plate 11 rotates, it will drive the trapezoidal block 13 to squeeze the extrusion block 14. When the extrusion block 14 is squeezed, it will drive the stroke rod 81 to move inside the stroke tube 15. At this time, the connecting ring 82 will squeeze the spring 83. When the extrusion block 14 is separated from the trapezoidal block 13, the spring 83 will undergo elastic deformation and drive the stroke rod 81 back to its original position. The movement of the stroke rod 81 will drive the extrusion block 14 to strike the feed tube 2, and then the raw materials of medicine will be continuously placed into the expansion tube 3. In this way, the unblocking rod 12 can prevent the raw materials of medicine from being blocked in the feed tube 2, and the vibration force of the extrusion block 14 when it strikes can also play a role in unblocking.
[0040] In summary, this screening machine with an anti-clogging structure, through the coordinated use of the expanding pipe 3, fixing ring 4, hexagonal shell 5, L-shaped rod 6, rotating assembly 7, and striking assembly 8, allows the stroke rod 81 to move and drive the extrusion block 14 to strike the feed pipe 2, thereby continuously placing the raw pharmaceutical materials into the expanding pipe 3. In this way, the unblocking rod 12 can prevent the raw pharmaceutical materials from clogging in the feed pipe 2, and the vibration force of the extrusion block 14 when striking can also play a role in unblocking. This solves the problem that the feed pipe of the pharmaceutical raw material screening machine is the most prone to clogging, and when the feeding speed is too fast or the material is too wet or viscous, blockage may occur at the feed inlet.
