Description

Technical Field

[0001] This utility model relates to the field of mixing technology, specifically to a material mixing device for processing pain relief spray. Background Technology

[0002] As a type of external spray widely used to relieve various types of pain, the core production process of pain relief sprays cannot be separated from the efficient dissolution and mixing of powdered or granular drugs with solvents. These drug ingredients (such as granules of Chinese herbal extracts, powders of chemical analgesics, etc.) are the key to ensuring the analgesic effect of the spray. Precise mixing is required to achieve uniform dispersion of the active ingredients in the solution. For example, the invention patent with application number 201610418747.8, a traditional Chinese medicine spray for reducing swelling and relieving pain in orthopedics and its preparation method, clearly discloses that its production process requires the use of a large amount of pulverized traditional Chinese medicine powder and granular drugs. These materials need to be fully mixed with a specific solvent to exert their medicinal effects. However, existing conventional mixing equipment generally has unavoidable technical pain points when handling the mixing and dissolving of such granular and powdery drugs: affected by the "tea paradox principle", that is, in the rotating flow solution, the granular drugs will gradually settle and gather in the central area of ​​the bottom surface of the mixing equipment under the combined action of centrifugal force and fluid viscosity, and cannot be fully circulated with the solution. This phenomenon directly leads to obvious density stratification of the solution within the mixing equipment. The bottom layer, due to the accumulation of a large number of incompletely dissolved drug particles, has a significantly higher density than the upper layer. This not only greatly reduces the contact area between the drug particles and the solvent, significantly decreasing the dissolution rate, but also causes uneven distribution of the active ingredients, resulting in low overall mixing efficiency. This poor mixing effect prolongs the production cycle, increases energy costs, and may affect the efficacy stability and safety of the final spray product. It also brings many inconveniences to the process control and quality control of production operators, making it difficult to meet the demand for large-scale, high-quality production of pain relief sprays.

[0005] Optionally, a drive motor with a drive shaft extending into the mixing tank is fixedly installed at the top of the mixing tank, an active stirring tank is slidably connected to the top of the driven stirring tank, the top of the active stirring tank is fixedly connected to the rotating shaft at the bottom of the drive motor, and a second tension spring is fixedly connected to the upper surface of the driven stirring tank, the top of the second tension spring being fixedly connected to the inner top surface of the active stirring tank.

[0006] Optionally, a pressure baffle is fixedly connected to the top of the inner wall of the mixing tank, and a pressure rod with one end able to abut against the lower surface of the pressure baffle is fixedly connected to the top of the outer peripheral surface of the driven stirring tank.

[0007] Optionally, a first auxiliary mounting plate is fixedly connected to the top of the inner circumferential surface of the auxiliary riser, and a plurality of first springs are fixedly connected to the upper surface of the first auxiliary mounting plate. The end of the first spring away from the first auxiliary mounting plate is fixedly connected to the inner top surface of the auxiliary riser.

[0008] Optionally, the auxiliary rising cylinder has multiple second connecting ports in the middle.

[0009] Optionally, the unidirectional flow component includes a second auxiliary mounting plate fixedly connected to the bottom of the inner circumferential surface of the driven stirring tank, and the lower surface of the second auxiliary mounting plate is provided with a plurality of second liquid inlets. An auxiliary support plate is fixedly connected to the bottom of the inner circumferential surface of the driven stirring tank, and the upper surface of the auxiliary support plate is provided with a baffle that can be pushed open by the solution.

[0010] Optionally, the upper surface of the auxiliary support plate is provided with a slot adapted to the baffle, and the center of the lower surface of the auxiliary support plate is provided with a first communication port communicating with the slot.

[0011] (III) Beneficial Effects This utility model provides a material mixing device for processing pain relief spray, which has the following beneficial effects: 1. The material mixing equipment for processing the pain relief spray, through the coordinated arrangement of the driven stirring tank, auxiliary rising tank, auxiliary rising cylinder, extrusion grinding tank, first auxiliary mounting plate and first spring, can realize dynamic adjustment of the stirring position and efficient grinding of particulate materials, shorten the particle dissolution time and improve the mixing efficiency. The drive motor drives the active stirring tank to rotate, which in turn drives the driven stirring tank to rotate synchronously. The stirring rod on its outer surface initially stirs the solution in the mixing tank. At the same time, the downward pressing rod on the outer periphery of the driven stirring tank moves down along the inclined arc surface of the downward pressing baffle, driving the driven stirring tank to move down synchronously to adjust the distribution of the stirring rods and enhance the uniformity of stirring. The driven stirring tank drives the auxiliary rising cylinder and extrusion grinding tank to complete the "downward movement + rotation" action through the auxiliary rising tank. When the extrusion grinding tank contacts the bottom surface of the mixing tank, it gathers the particles at the bottom of the tank and grinds them, effectively shortening the dissolution time and improving the overall mixing efficiency.

[0012] 2. The material mixing equipment used for processing this pain relief spray, through the linkage of a unidirectional flow component, an auxiliary rising tank, an auxiliary rising cylinder, a squeezing and grinding tank, and a first spring, can form an up-and-down convection circulation of the solution in the mixing tank, ensuring consistent solution density and improving mixing uniformity. When the squeezing and grinding tank contacts the bottom of the tank, the driven stirring tank moves down to squeeze the internal solution. Initially, it flows back through the second connecting port. After the second connecting port is blocked, the solution enters the unidirectional flow component through the second inlet, pushes open the baffle, and flows into the top of the solution from the first outlet, forming convection. After the lowering rod disengages from the lowering baffle, the driven stirring tank and the auxiliary rising cylinder reset under the action of the second tension spring and the first spring. The second connecting port reopens to draw in the solution from the bottom of the tank, preparing for the next cycle, ultimately ensuring consistent solution density throughout and improving mixing uniformity and efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figures 1 to 4 This utility model provides a technical solution: a material mixing device for processing analgesic sprays, including a mixing tank 1, wherein the mixing tank 1 has a feed opening at the top and a discharge pipe at the bottom, and a switch valve is installed on the discharge pipe. A driven stirring tank 2, which can move up and down and rotate, is installed inside the mixing tank 1. The driven stirring tank 2 has a rectangular barrel structure, and its specific shape can be referred to... Figure 4 An auxiliary rising tank 4 is fixedly connected to the bottom of the driven stirring tank 2. An auxiliary rising cylinder 5 that can move up and down is provided inside the auxiliary rising cylinder 4. An extrusion grinding tank 6 that can squeeze the solution into the driven stirring tank 2 is fixedly connected to the bottom of the auxiliary rising cylinder 5. The extrusion grinding tank 6 is made of medical rubber material, which can meet the usage requirements of medical-related scenarios. The outer surface of the extrusion grinding tank 6 can abut against the bottom surface of the mixing tank 1. A one-way flow component is provided at the bottom of the inner circumference of the driven stirring tank 2.

[0017] Please see Figures 2 to 3 A drive motor with a drive shaft extending into the mixing tank 1 is fixedly installed at the top of the mixing tank 1. An active stirring tank 15 is slidably connected to the top of the driven stirring tank 2. The top of the active stirring tank 15 is fixedly connected to the rotating shaft at the bottom of the drive motor. A second tension spring 18 is fixedly connected to the upper surface of the driven stirring tank 2. The top of the second tension spring 18 is fixedly connected to the inner top surface of the active stirring tank 15. Therefore, when the drive motor is in operation, its bottom drive shaft will drive the active stirring tank 15 to rotate stably and synchronously. The active stirring tank 15 then drives the driven stirring tank 2 to rotate synchronously. Since there are multiple stirring rods distributed on the outer surface of the driven stirring tank 2, this rotation action can efficiently stir the solution in the mixing tank 1.

[0018] Please see Figures 2 to 3 A pressure baffle 17 is fixedly connected to the top of the inner wall of the mixing tank 1, and a pressure rod 16 with one end able to abut against the lower surface of the pressure baffle 17 is fixedly connected to the top of the outer periphery of the driven stirring tank 2. The lower surface of the pressure baffle 17 is inclined arc-shaped. When the driven stirring tank 2 rotates, the pressure rod 16 rotates synchronously with it. During the rotation, the end of the pressure rod 16 away from the driven stirring tank 2 will abut against the lower surface of the pressure baffle 17 and move downward along the inclined arc-shaped surface, thereby driving the driven stirring tank 2 to move downward synchronously. The downward movement of the driven stirring tank 2 can dynamically adjust the distribution position of the stirring rod in the mixing tank 1, effectively enhancing the mixing effect of the stirring rod on the solution in the tank.

[0019] Please see Figures 2 to 4 The top of the inner circumferential surface of the auxiliary rising cylinder 5 is fixedly connected to a first auxiliary mounting plate 7. Multiple first springs 8 are fixedly connected to the upper surface of the first auxiliary mounting plate 7. The end of the first spring 8 away from the first auxiliary mounting plate 7 is fixedly connected to the inner top surface of the auxiliary rising cylinder 4. Multiple second communication ports 19 are opened in the middle of the auxiliary rising cylinder 5. Therefore, when the driven stirring tank 2 moves downward, the auxiliary rising tank 4 drives the auxiliary rising cylinder 5 to move downward synchronously. At the same time, the rotation of the driven stirring tank 2 also drives the auxiliary rising cylinder 5 to operate synchronously. Under the superposition of the dual actions of "moving downward + rotating", the auxiliary rising cylinder 5 further drives the extrusion grinding tank 6 to complete synchronous movement and rotation. When the extrusion grinding tank 6 contacts the bottom surface of the mixing tank 1, based on the principle of the tea paradox (in a rotating fluid, particles are subjected to the combined action of centrifugal force and viscous force, and will gather towards the center of the container), it can quickly gather the particle material at the center of the bottom of the tank; then, through the shear grinding effect (the mechanical force squeezes and shears the particles, destroying the particle structure), the material is ground, effectively shortening the dissolution time of the particles in the solution, and ultimately significantly improving the overall mixing efficiency.

[0020] Please see Figures 2 to 4 The unidirectional flow component includes a second auxiliary mounting plate 11 fixedly connected to the bottom of the inner circumferential surface of the driven stirring tank 2, and the lower surface of the second auxiliary mounting plate 11 is provided with a plurality of second liquid inlets 14. An auxiliary support plate 9 is fixedly connected to the bottom of the inner circumferential surface of the driven stirring tank 2, and the upper surface of the auxiliary support plate 9 is provided with a baffle 10 that can be pushed open by the solution. The upper part of the driven stirring tank 2 is provided with a plurality of first liquid outlets 3. The driven stirring tank 2 can be connected to the auxiliary rising tank 4 through the second liquid inlets 14, and the driven stirring tank 2 can be connected to the mixing tank 1 through the first liquid outlets 3. In addition, the auxiliary rising cylinder 5 can be connected to the mixing tank 1 through the second connecting port 19.

[0021] Please see Figures 1 to 4 The upper surface of the auxiliary support plate 9 is provided with a slot that is compatible with the baffle 10. The center of the lower surface of the auxiliary support plate 9 is provided with a first communication port 13 that communicates with the slot. The center of the upper surface of the second auxiliary mounting plate 11 is fixedly connected to a first tension spring 12. The end of the first tension spring 12 away from the second auxiliary mounting plate 11 passes through the first communication port 13 and is fixedly connected to the baffle 10. When the extrusion grinding barrel 6 does not contact the bottom surface of the mixing tank 1, the auxiliary rising barrel 4, the auxiliary rising cylinder 5 and the extrusion grinding barrel 6 will be filled with the solution at the bottom of the mixing tank 1 through the second connecting port 19. As the driven stirring barrel 2 moves down and drives the extrusion grinding barrel 6 to contact the bottom surface of the mixing tank 1, the extrusion grinding barrel 6 rotates and grinds the particle material. At the same time, the continuous downward movement of the driven stirring barrel 2 will squeeze the solution inside the auxiliary rising barrel 4, the auxiliary rising cylinder 5 and the extrusion grinding barrel 6. At this time, the solution inside the auxiliary rising barrel 4, the auxiliary rising cylinder 5 and the extrusion grinding barrel 6 will first flow back into the mixing tank 1 through the second connecting port 19. When the bottom end of the auxiliary riser 5 touches the bottom surface of the mixing tank 1 through the extrusion grinding barrel 6, the auxiliary riser 5 will drive the first auxiliary mounting plate 7 to move into the auxiliary riser 4. The second connecting port 19 will be gradually blocked by the auxiliary riser 4. When the second connecting port 19 is completely blocked, the auxiliary riser 5 will continue to move. The solution inside the auxiliary riser 4, the auxiliary riser 5 and the extrusion grinding barrel 6 will enter between the auxiliary support plate 9 and the second auxiliary mounting plate 11 through the second liquid inlet 14. Then, it will overcome the tension of the first tension spring 12 to push open the baffle 10 and finally flow into the top of the solution in the mixing tank 1 from the first liquid outlet 3. This process creates convective mixing between the bottom and top solutions in mixing tank 1, ultimately resulting in a uniform density throughout the solution and significantly improving overall mixing efficiency. At the same time, when the pressure rod 16 disengages from the pressure baffle 17, the driven stirring tank 2 is pulled upward and reset by the pulling force of the second tension spring 18. At the same time, the first spring 8 pushes the first auxiliary mounting plate 7, causing the auxiliary rising cylinder 5 to reset synchronously. As the auxiliary rising cylinder 5 resets, the second connecting port 19 reopens, and the solution at the bottom of the mixing tank 1 immediately re-enters the auxiliary rising cylinder 4, the auxiliary rising cylinder 5, and the extrusion grinding tank 6, preparing for the next cycle.

[0022] In summary, when the material mixing equipment for processing the pain relief spray is in use, after the drive motor is started, its bottom drive shaft will drive the active stirring tank 15 to rotate synchronously, which in turn drives the driven stirring tank 2 to rotate synchronously. Multiple stirring rods on the outer surface of the driven stirring tank 2 will stir the solution in the mixing tank 1. During the rotation of the driven stirring tank 2, the pressing rod 16 on the top of the outer peripheral surface of the driven stirring tank 2 will abut against the lower surface of the pressing baffle 17 on the top of the inner wall of the mixing tank 1, and move downward along its inclined arc surface, driving the driven stirring tank 2 to move downward synchronously. When the driven stirring tank 2 moves down, it will drive the auxiliary rising tank 5 to move down synchronously through the auxiliary rising tank 4 fixedly connected to the bottom. At the same time, the rotation of the driven stirring tank 2 will drive the auxiliary rising tank 5 to rotate, thereby driving the extrusion grinding tank 6 at the bottom of the auxiliary rising tank 5 to move and rotate synchronously. When the extrusion grinding tank 6 contacts the bottom surface of the mixing tank 1, it will grind the granular material gathered in the center of the bottom surface of the mixing tank 1, accelerating the dissolution of the granules. Meanwhile, the driven stirring tank 2 continues to move downward, which will squeeze the solution in the auxiliary rising tank 4, the auxiliary rising cylinder 5 and the squeezing grinding tank 6. Initially, the solution flows back into the mixing tank 1 through the second connecting port 19. After the auxiliary rising cylinder 5 touches the bottom surface of the mixing tank 1 through the squeezing grinding tank 6, the auxiliary rising cylinder 5 drives the first auxiliary mounting plate 7 to move upward. The second connecting port 19 is blocked by the auxiliary rising tank 4, and the solution enters between the auxiliary support plate 9 and the second auxiliary mounting plate 11 through the second liquid inlet 14. It overcomes the tension of the first tension spring 12 and pushes open the baffle 10, flowing into the top of the solution in the mixing tank 1 from the first liquid outlet 3, realizing the convection mixing of the upper and lower solutions in the tank. When the pressure rod 16 disengages from the pressure baffle 17, the second tension spring 18 pulls the driven stirring tank 2 upward to reset, the first spring 8 pushes the first auxiliary mounting plate 7 to drive the auxiliary rising cylinder 5 to reset synchronously, the second connecting port 19 reopens, and the solution at the bottom of the mixing tank 1 re-enters the auxiliary rising cylinder 4, the auxiliary rising cylinder 5 and the extrusion grinding tank 6 to prepare for the next mixing cycle.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
