Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and more specifically, to a screening machine for processing raw materials of traditional Chinese medicine decoction pieces. Background Technology

[0002] As an important form of clinical medicine in traditional Chinese medicine, the quality of prepared herbal pieces directly affects the efficacy of prescriptions. Before processing the raw materials for prepared herbal pieces, it is necessary to remove impurities such as mud and ash from the surface of the raw materials. At this time, a drum-type sieve machine is often used to remove impurities attached to the surface of the raw materials to ensure the accuracy of subsequent processing and preparation and the stability of the efficacy.

[0003] Currently, most drum-type medicine screening machines on the market use a fixed screen structure. After prolonged use, impurities easily accumulate on the screen surface, affecting screening efficiency. This requires operators to disassemble, clean, or replace the screen. However, existing drum screens mostly use bolt fixing or welding processes, resulting in low modularity and poor disassembly and assembly efficiency. Disassembly and assembly require removing a large number of fasteners or cutting welded parts, relying on specialized tools. Each disassembly requires a significant amount of time to loosen the bolts one by one, greatly affecting the screen replacement efficiency. In addition, the inside of the medicine screening machine is a closed cavity with a narrow gap between the screen and the cylinder wall, making it difficult for operators to operate in the confined internal space and severely limiting their range of motion. Therefore, improvements are needed. Utility Model Content

A pull rod is fixedly installed on the back of the ring, and the outer surface of the pull rod is slidably connected to the interior of an arc-shaped groove. A moving rod is movably fitted on the front of the ring, and a moving block is movably fitted on the other end of the moving rod. A slider and an insert rod are fixedly installed on the outer surface of the moving block. A limit block is slidably connected to the outer surface of the slider, and the outer surface of the limit block is fixedly connected to the interior of the fixed box. A fixing ring is movably fitted on the outer surface of the insert rod, and a positioning ring is movably fitted on the outer surface of the fixing ring. The back of the positioning ring is fixedly connected to the interior of the fixed box. A sieve barrel is fixedly installed on the front of the fixing ring, and a positioning block is movably fitted into the interior of the front of the sieve barrel. The positioning block is fixedly connected to the interior of the fixed box.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This sieve machine for processing raw materials of traditional Chinese medicine decoction pieces eliminates the traditional bolt fastening and welding methods due to the design of the disassembly and assembly mechanism. The operator can disassemble and assemble the sieve barrel by moving the pull rod along the inside of the arc groove. This completely solves the problem of inconvenient operation caused by the small internal space of traditional sieve machines. The time for a single disassembly and assembly is shortened to less than a few minutes, which improves the operating efficiency, greatly reduces the labor intensity, and significantly reduces the equipment downtime for maintenance. In addition, the feature of the sieve barrel being independently detachable allows the mud, ash, dregs and other impurities attached to the screen surface to be fully exposed, which is convenient for the operator to clean quickly and effectively avoid the problem of reduced screening efficiency due to the accumulation of impurities.

[0020] 2. This screening machine for processing raw materials of traditional Chinese medicine decoction pieces features a stirring blade design that efficiently agitates the raw materials, allowing impurities attached to them to be quickly separated. Due to the cylinder design, when the cylinder operates, it drives the entire fixed box to move via the third hinge block. The fixed box then rotates around the hinge point between the first and second hinge blocks, causing it to tilt. At this point, the raw materials inside the screening barrel slide out under gravity, achieving automatic feeding and facilitating daily use by operators. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1 to 8 As shown, this utility model provides a screening machine for processing raw materials of traditional Chinese medicine decoction pieces, comprising:

[0032] The fixed box 1 has an arc-shaped groove 2 on its back and a collection box 14 at the bottom inside the fixed box 1.

[0033] The disassembly and assembly mechanism is located inside the fixed box 1;

[0034] The disassembly and assembly mechanism includes a ring 3, the outer surface of which is movably connected to the interior of the fixed box 1. A pull rod 4 is fixedly installed on the back of the ring 3, and the outer surface of the pull rod 4 is slidably connected to the interior of the arc groove 2. A moving rod 5 is movably connected to the front of the ring 3, and a moving block 6 is movably connected to the other end of the moving rod 5. A slider 7 and an insert rod 9 are fixedly installed on the outer surface of the moving block 6. A limit block 8 is slidably connected to the outer surface of the slider 7, and the outer surface of the limit block 8 is fixedly connected to the interior of the fixed box 1. A fixing ring 10 is movably connected to the outer surface of the insert rod 9, and a positioning ring 11 is movably connected to the outer surface of the fixing ring 10. The back of the positioning ring 11 is fixedly connected to the interior of the fixed box 1. A screen barrel 12 is fixedly installed on the front of the fixing ring 10, and a positioning block 13 is movably connected to the interior of the front of the screen barrel 12. The positioning block 13 is fixedly connected to the interior of the fixed box 1.

[0035] When the operator moves the pull rod 4 along the inside of the arc groove 2, the ring 3 will rotate under the action of the pull rod 4. At this time, the ring 3 will drive the four moving blocks 6 through the four moving rods 5. The four moving blocks 6 will then drive the four sets of sliders 7 to move outward along the inside of the four sets of limit blocks 8. At the same time, the four insert rods 9 will move outward under the action of the four moving blocks 6. Subsequently, the four insert rods 9 will disengage from the fixed ring 10 during the movement. At this time, the operator can hold the handle on the screen barrel 12 and pull the screen barrel 12 out of the fixed box 1, thus completing the disassembly of the screen barrel 12. When the operator needs to install the screen barrel 12, the operator first places the screen barrel 12 into the fixed box 1. During this process, the operator needs to align the inside of the circular groove on the front of the screen barrel 12 with the positioning block 13. Due to the design of the positioning block 13, it will play a good positioning role for the screen barrel 12. When the operator fully inserts the screen barrel 12 into the fixed box 1, the outer surface of the positioning block 13 will fit into the inside of the circular groove of the screen barrel 12. At this time, the operator drives the pull rod 4 to move in the opposite direction along the inside of the arc groove 2. At this time, the four insertion rods 9 will move inward and insert into the inside of the fixing ring 10, thereby completing the fixing of the screen barrel 12.

[0036] Among them, a fixing block 15 is fixedly installed on the left side of the back of the fixing box 1, and a lever 16 is connected to the inside of the fixing block 15.

[0037] Because the paddle 16 is slidably connected to the inside of the fixed block 15, the paddle 16 can move left and right along the inside of the fixed block 15.

[0038] Among them, a round rod 17 is fixedly installed on the right side of the lever 16, and the outer surface of the round rod 17 is movably connected to the inside of the pull rod 4.

[0039] Due to the design of the round rod 17, when the round rod 17 is inserted into the pull rod 4, it will lock the movement of the pull rod 4. When the operator moves the lever 16, the lever 16 will drive the round rod 17 to move to the left. At this time, the round rod 17 will release its contact with the inside of the pull rod 4 during the movement, thereby releasing the locking effect on the pull rod 4.

[0040] A spring 18 is fixedly installed on the left side of the paddle 16, and the left end of the spring 18 is fixedly connected to the inside of the fixing block 15.

[0041] When the paddle 16 moves to the left, it will compress the spring 18. Due to the elastic force of the spring 18, the movement of the paddle 16 will be effectively reset.

[0042] Among them, a movable door 19 is hinged to the right side of the front of the fixed box 1, and a fixed shaft 20 is fixedly installed on the left side of the front of the fixed box 1. A rotating block 21 is movably sleeved on the outer surface of the fixed shaft 20.

[0043] When the operator pulls the movable door 19, it will rotate around the hinge point with the fixed box 1. When the outer surface of the movable door 19 is in contact with the front of the screen barrel 12 during rotation, the movable door 19 will keep the inside of the screen barrel 12 closed. At this time, the operator will turn the rotating block 21, which will make the outer surface of the rotating block 21 contact the outer surface of the movable door 19. The rotating block 21 will then block the movement of the movable door 19, thereby keeping the inside of the screen barrel 12 closed.

[0044] Among them, a fixed frame 22 is fixedly installed on the back of the fixed box 1, a motor 23 is fixedly installed on the back of the fixed frame 22, a long shaft 24 is fixedly sleeved on the output shaft of the motor 23, and a stirring blade 25 is fixedly sleeved on the outer surface of the long shaft 24.

[0045] When the motor 23 is running, the long shaft 24 will drive the stirring blade 25 to rotate. At this time, the stirring blade 25 will turn over the raw material inside the screen barrel 12, so that the impurities attached to the raw material will be quickly separated from the raw material. Then, these impurities will fall through the screen holes of the screen barrel 12 into the collection box 14 for collection.

[0046] The first hinge block 30 is fixedly installed on the front side of the bottom end of the fixed box 1, and the second hinge block 31 is hinged inside the first hinge block 30.

[0047] Since the first hinge block 30 and the second hinge block 31 are hinged together, the entire fixed box 1 can rotate around the hinge point of the first hinge block 30 and the second hinge block 31. At this time, the entire fixed box 1 will become tilted during rotation, so that the raw material after the impurity removal and screening can automatically slide out of the inside of the screen barrel 12.

[0048] The bottom end of the second hinge block 31 is fixedly mounted with a fixing plate 32, and the bottom end of the fixing plate 32 is fixedly mounted with a base frame 33.

[0049] Due to the design of the fixing plate 32 and the base frame 33, the equipment as a whole will be well supported, so that the equipment can be placed stably on the ground.

[0050] The base frame 33 is provided with a square plate 34, and a cylinder 35 is hinged to the top of the square plate 34.

[0051] Since the base frame 33 is hinged to the square plate 34, the cylinder 35 can rotate around the hinge point between the base frame 33 and the square plate 34.

[0052] The cylinder 35 has a third hinge block 36 hinged to its top end, and the top end of the third hinge block 36 is fixedly connected to the bottom end of the fixed box 1.

[0053] When the cylinder 35 is running, it will push the fixed box 1 through the third hinge block 36, so that the fixed box 1 rotates around the hinge point of the first hinge block 30 and the second hinge block 31.

[0054] Working principle and usage process of this utility model:

[0055] When the operator needs to screen the raw materials to remove impurities, the operator first pours the raw materials into the screen barrel 12. Then, the operator pulls the handle on the movable door 19, causing the movable door 19 to rotate around the hinge point with the fixed box 1. Subsequently, the outer surface of the movable door 19 will contact the front of the screen barrel 12 during rotation, at which point the movable door 19 will close the interior of the screen barrel 12. Then, the operator turns the rotating block 21, causing the rotating block 21 to rotate around the fixed shaft 20. Subsequently, the outer surface of the rotating block 21 will contact the movable door 19 during rotation, at which point the rotating block 21 will lock the movable door 19. Next, the operator starts the motor 23, at which point the long shaft 24 will drive the stirring blade 25 to rotate. When the stirring blade 25 rotates, it will turn the raw materials inside the screen barrel 12. During this process, the impurities attached to the surface of the raw materials will fall off the raw materials through continuous movement and friction. Subsequently, these impurities will fall through the screen holes on the screen barrel 12 into the collection box 14 for collection.

[0056] After the impurities on the raw materials are cleaned, the operator turns off the motor 23. At this time, the operator starts the cylinder 35. The top of the cylinder 35 will squeeze and push the third hinge block 36, causing the third hinge block 36 to drive the entire fixed box 1 to rotate around the hinge point of the first hinge block 30 and the second hinge block 31. During this process, the cylinder 35 will swing around the hinge point with the square plate 34. At the same time, the entire fixed box 1 will become tilted during rotation. Then, the operator will turn the rotating block 21 to lock the movable door 19. Then, the operator will pull the movable door 19 to make the movable door 19 disengage from the obstruction inside the screen barrel 12. Since the entire fixed box 1 is in a tilted state, the raw materials inside the screen barrel 12 will move out of the screen barrel 12 under the action of gravity, thus realizing the function of automatic feeding of raw materials after screening and dust removal.

[0057] When the operator needs to disassemble or assemble the screen barrel 12, the operator first moves the lever 16, causing it to move to the left along the inside of the fixed block 15. At this time, the spring 18 will be compressed, and simultaneously the lever 16 will drive the round rod 17 to move to the left. Subsequently, the outer surface of the round rod 17 will release its contact with the pull rod 4 during the movement, thus releasing the locking effect of the round rod 17 on the pull rod 4. Immediately afterwards, the operator holds the pull rod 4 and drives it to move along the inside of the arc groove 2. At this time, the ring 3 will rotate under the action of the pull rod 4. During this process... The circular ring 3 will simultaneously drive the four moving rods 5 to move, causing the four moving rods 5 to pull the four moving blocks 6 respectively. Due to the design of the limiting block 8, the movement of the slider 7 will be limited. At this time, the four moving blocks 6 will drive the four sets of sliders 7 to move outward along the inside of the four sets of limiting blocks 8. At the same time, the four insert rods 9 will move outward under the drive of the four moving blocks 6. Subsequently, the outer surface of the four insert rods 9 will release the sleeve relationship with the fixed ring 10 during the outward movement, thereby releasing the locking effect on the entire fixed ring 10. At this time, the operator can hold the screen barrel 12. Two handles allow the screen barrel 12 to be pulled out entirely from the fixed box 1, thus completing the disassembly of the screen barrel 12. When the operator needs to install the screen barrel 12, the operator inserts the screen barrel 12 entirely into the fixed box 1 from the front. During this process, the operator needs to align the inside of the circular groove on the front of the screen barrel 12 with the positioning block 13, ensuring that the positioning block 13 is located inside the circular groove on the front of the screen barrel 12 when the screen barrel 12 is fully inserted into the fixed box 1. Due to the design of the positioning block 13, it will provide good positioning for the screen barrel 12. After the operator inserts the screen barrel 12 into the fixed box 1, the operator moves the lever 16 again and drives the pull rod 4 to move in the opposite direction. At this time, the four insert rods 9 will move inward and insert into the fixed ring 10. At this time, the operator releases the lever 16. Due to the elastic force of the spring 18, the spring 18 will drive the round rod 17 to return to the right through the lever 16, so that the round rod 17 is inserted into the pull rod 4. At this time, the movement of the entire pull rod 4 will be locked, so as to achieve the effect of fixing the screen barrel 12 as a whole, thereby realizing the function of conveniently assembling and disassembling the screen barrel 12.
