Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a material mixing device for laboratory use. Background Technology

[0002] In many fields of modern scientific research, such as chemistry, materials science, and biomedicine, there are higher requirements for the mixing of materials. It is necessary to uniformly mix a variety of raw materials with different properties to ensure that the materials have the expected performance.

[0003] In early laboratory research, manual mixing of materials was a common practice. Researchers typically used simple tools such as glass rods and stirring rods to mix materials in containers such as beakers. However, this method had many drawbacks. The uniformity of the mixture was poor, and the mixing effect of different batches could vary greatly, which seriously affected the repeatability and reliability of the experimental results. On the other hand, manual operation was inefficient, and for some experiments that required mixing large quantities of materials, it consumed a lot of researchers' time and energy.

[0004] While some simple mechanical mixing devices improve mixing efficiency and uniformity to a certain extent compared to manual mixing, these early mechanical mixing devices have relatively limited functions and can usually only perform simple stirring operations. They cannot meet the diverse requirements of complex experiments for the mixing process and are prone to problems such as material agglomeration and insufficient mixing, which leads to a significant increase in mixing time and reduced experimental efficiency. Furthermore, the opening and closing of the lid is not convenient enough and cannot effectively secure mixing containers of various sizes, so its applicability needs to be improved. In view of this, we propose a material mixing device for laboratory use. Utility Model Content

[0005] The purpose of this invention is to provide a laboratory material mixing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A laboratory material mixing device includes a base, a bracket fixedly mounted on the upper surface of the base's bottom end, a mixing container placed on the top of the base, and a mixing component disposed on the top of the base. The mixing component includes:

[0008] A U-shaped frame is fixedly installed on the outer wall of the top of the support. An asynchronous motor is fixedly installed on the top of the U-shaped frame. A threaded rod is fixedly installed on the bottom output end of the asynchronous motor. The threaded rod is rotatably installed on the U-shaped frame. A T-shaped plate is threaded onto one end of the threaded rod.

[0009] A slide rail is fixedly installed on the bracket, a slider is fixedly installed on the outer wall of the T-shaped plate, the slider is slidably installed on the slide rail, and a bucket lid is fixedly installed at the bottom of the other end of the T-shaped plate;

[0010] An asynchronous motor is fixedly installed on the outer wall of the T-shaped plate. A stirring shaft is fixedly installed at the bottom output end of the asynchronous motor. The stirring shaft passes through the T-shaped plate. A stirring paddle is fixedly installed at the bottom end of the stirring shaft. A heater is fixedly installed on the top of the bucket lid. A heating roller is provided at the bottom end of the heater.

[0011] Preferably, there are two sets of sliders and slide rails, and both sets of sliders and slide rails are symmetrically arranged at both ends of the T-shaped plate with the vertical center line of the T-shaped plate as the axis of symmetry, so that the movement of the T-shaped plate is more stable.

[0012] Preferably, the stirring paddle is provided in multiple sets, and the multiple sets of stirring paddles are arranged in an equally spaced circular array with the center of the circular cross-section of the stirring shaft as the array center, so as to achieve better mixing effect.

[0013] Preferably, the movement trajectory of the stirring paddle does not intersect with that of the heating roller to prevent motion interference.

[0014] Preferably, the base is provided with a fixing component, the fixing component includes a fixing block, the fixing block is fixedly installed on the top of the base, and a threaded post is installed inside the fixing block.

[0015] Preferably, a rotating handle is fixedly installed at one end of the threaded column, and a rubber plate is fixedly installed at the other end of the threaded column, with the rubber plate slidingly conforming to the arc-shaped outer wall of the mixing tank.

[0016] Preferably, multiple sets of the fixing block, threaded column, rotating handle, and rubber plate are provided, which can better clamp and fix the mixing barrel with a wider range of outer diameters, thereby improving the applicability of the device body.

[0017] Compared with the prior art, the present invention provides a laboratory material mixing device, which has the following advantages:

[0018] 1. This laboratory material mixing device, in order to better mix laboratory materials, is equipped with mixing components. After multiple materials are placed inside the mixing tank, the asynchronous motor on the U-shaped frame is first started, causing the threaded rod to rotate. This allows the T-shaped plate to move the tank lid downwards, sealing the top of the mixing tank. At the same time, the slider slides on the slide rail. The asynchronous motor is started in both directions, causing the stirring shaft to drive the stirring paddle to rotate alternately in both directions for mixing. This avoids the material vortex caused by single axial rotation. Simultaneously, the heater is started, and together with the heating roller, the materials are heated, thus achieving better mixing of laboratory materials.

[0019] 2. In order to improve the applicability of the material mixing device in this laboratory, a fixing component is set up. When the mixing barrel is placed on the base, the screw thread is rotated inside the fixing block by rotating the handle, so that the rubber plate is close to the arc-shaped outer wall of the mixing barrel. This allows for better clamping and fixing of mixing barrels with a wider range of outer diameters, thereby improving the applicability of the device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0027] Please see Figure 1 - Figure 4This utility model provides a technical solution:

[0028] A laboratory material mixing device includes a base 1, a support 2 fixedly installed on the upper surface of the bottom end of the base 1, a mixing tank 3 placed on the top of the base 1, and laboratory materials to be mixed inside the mixing tank 3.

[0029] In one embodiment of this utility model, a mixing component 4 is provided at the top of the base 1. The mixing component 4 includes a U-shaped frame 41. The U-shaped frame 41 is fixedly installed on the outer wall of the top of the support 2. An asynchronous motor 42 is fixedly installed on the top of the U-shaped frame 41. A threaded rod 43 is fixedly installed at the bottom output end of the asynchronous motor 42. The threaded rod 43 is rotatably installed on the U-shaped frame 41. One end of a T-shaped plate 44 is threadedly installed on the threaded rod 43. A slide rail 45 is fixedly installed on the support 2. A slider 46 is fixedly installed on the outer wall of the T-shaped plate 44. The slider 46 is slidably installed on the slide rail 45. In addition, there are two sets of sliders 46 and slide rails 45, and both sets of sliders 46 and slide rails 45 are symmetrically arranged on both sides of the T-shaped plate 44 with the vertical center line of the T-shaped plate 44 as the axis of symmetry. The T-shaped plate 44 is fixedly mounted at one end, making its movement more stable. A bucket lid 47 is fixedly mounted at the bottom of the other end of the T-shaped plate 44. An asynchronous motor 48 is fixedly mounted on the outer wall of the T-shaped plate 44. A stirring shaft 49 is fixedly mounted at the bottom output end of the asynchronous motor 48. The stirring shaft 49 passes through the T-shaped plate 44. A stirring paddle 410 is fixedly mounted at the bottom end of the stirring shaft 49. In addition, there are three sets of stirring paddles 410, and the three sets of stirring paddles 410 are arranged in an equally spaced circular array with the center of the circular cross section of the stirring shaft 49 as the array center, which makes the mixing effect better. A heater 411 is fixedly mounted on the top of the bucket lid 47. A heating roller 412 is set at the bottom end of the heater 411. In addition, the movement trajectory of the stirring paddle 410 does not intersect with the heating roller 412 to prevent motion interference.

[0030] In this embodiment, the operator first pours various laboratory materials that need to be mixed into the mixing tank 3. The mixing tank 3 serves as a container for mixing materials, providing space for subsequent mixing operations. After the materials are added, the asynchronous motor 42 on the U-shaped frame 41 is started, which drives the threaded rod 43 to rotate. During the rotation of the threaded rod 43, since one end of the T-shaped plate 44 is threaded onto the threaded rod 43, according to the principle of thread transmission, the T-shaped plate 44 will move up and down along the axial direction of the threaded rod 43. During this process, when the T-shaped plate 44 moves downward, the lid 47 also moves downward until the lid 47 seals the top of the mixing tank 3, preventing materials from overflowing during the mixing process. At the same time, the slider 46 slides on the slide rail 45. The movement of the T-shaped plate 44 ensures its stability during the up-and-down motion, making its movement smoother. After the lid 47 is sealed, the asynchronous motor 48 is started in both directions, and the stirring shaft 49 rotates accordingly, causing the stirring paddle 410 to rotate and fully mix the material. Since the asynchronous motor 48 starts in both directions alternately, the stirring shaft 49 drives the stirring paddle 410 to rotate in both directions alternately, which can effectively avoid the material vortex caused by single axial rotation, resulting in an unsatisfactory mixing effect. While the stirring paddle 410 is mixing the material, the heater 411 is started, and its internal heating element converts electrical energy into heat energy. The heat generated by the heater 411 is transferred to the heating roller 412, which heats the material in the mixing barrel 3.

[0031] In one embodiment of this utility model, a fixing component 5 is provided on the base 1. The fixing component 5 includes a fixing block 51. The fixing block 51 is fixedly installed on the top of the base 1. A threaded post 52 is threadedly installed inside the fixing block 51. In addition, a rotating handle 53 is fixedly installed at one end of the threaded post 52, and a rubber plate 54 is fixedly installed at the other end of the threaded post 52. The rubber plate 54 slides against the arc-shaped outer wall of the mixing barrel 3. In addition, there are four sets of fixing blocks 51, threaded posts 52, rotating handles 53 and rubber plates 54, which are respectively located at the four corners of the top of the base 1, so as to better clamp and fix mixing barrels 3 with more outer diameters, thereby improving the applicability of the device body.

[0032] In this embodiment, the operator holds the handle 53 and rotates it. According to the principle of thread transmission, when the handle 53 rotates, the threaded post 52 begins to rotate inside the fixed block 51. Due to the threaded engagement between the threaded post 52 and the fixed block 51, the threaded post 52 will move along its axial direction. As the threaded post 52 moves, the rubber plate 54 also moves closer to the mixing tank 3, so that it can fit tightly against more mixing tanks 3 with different outer diameters, thereby stably clamping and fixing the mixing tank 3 and improving the applicability of the device body to mixing tanks 3 of different specifications.

[0033] All electrical components appearing in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the asynchronous motor 42, the asynchronous motor 48, and the heater 411. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts, and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
