Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, and specifically relates to a mixing device for the production of liquid polymer materials. Background Art

[0002] Liquid polymers refer to high molecular compounds that are in a liquid state under standard atmospheric pressure. Through their unique physical and chemical properties, liquid polymers play an important role in modern manufacturing and engineering, promoting the development of technologies such as rapid prototyping, high-performance material development, and customized production. Liquid polymers can be classified into oligomers, linear polymers, and network polymers according to their morphology. According to their properties, they can be further classified into thermosetting liquid polymers and thermoplastic liquid polymers.

[0003] For example, Chinese Patent (CN202120001550.0) discloses a mixing device for the production of two-component liquid polymer materials, including a mixing container. Support legs are fixedly installed at the bottom of the mixing container. Input pipes are fixedly connected to both sides of the mixing container, and the input pipes communicate with the interior of the mixing container. A first valve is provided in the middle of the input pipe. An output pipe is fixedly connected to the bottom of the mixing container, and a second valve is provided on the output pipe. A rotating shaft is rotatably installed inside the mixing container. In the mixing device for the production of two-component liquid polymer materials of the present utility model, the first electric push rod and the second electric push rod can drive the limiting plate to move up or down, so as to adapt to different capacities. The limiting plate is close to the liquid level of the materials inside the mixing container and plays a limiting role on the materials during the stirring and mixing process, avoiding large-span splashing, facilitating subsequent cleaning, and bringing better application prospects.

[0004] In the above solution, the stirring blades are fixed in the mixing tank, which results in the inability to take out the stirring blades. When it is necessary to change the type of stirring blades or perform maintenance, it may be necessary to replace the entire mixing tank or carry out complex disassembly operations, increasing the cost and time of maintenance and operation. The fact that the stirring blades are fixed inside the mixing tank means that they cannot be easily taken out for cleaning and maintenance. This may lead to incomplete cleaning or the inability to effectively handle the residues inside the mixing tank, affecting the hygiene and production quality of the next use. To solve the above problems, a mixing device for the production of liquid polymer materials is proposed herein. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The following preferred embodiments are only examples, and those skilled in the art can think of other obvious variations.

[0020] Refer to Figures 1 - 3As shown in the figure, a mixing device for the production of liquid polymer materials includes a bottom plate 1. At the rear side of the upper surface of the bottom plate 1, a column 2 is fixedly connected. At the upper end of the front side of the column 2, two support plates 3 are fixedly connected. At the middle part of the front side of the column 2, a fixed plate 5 is fixedly connected. Between the lower parts of the two support plates 3 and the fixed plate 5, guide rods 7 are fixedly connected. Above the fixed plate 5, an installation disc 6 is arranged. The installation disc 6 is slidably connected to the surface of the guide rods 7. Above the two support plates 3, an installation frame 4 is fixedly connected. Above the installation frame 4, a lifting motor 8 is fixedly installed. The output end of the lifting motor 8 is fixedly connected to a first threaded rod 9. The surface of the first threaded rod 9 is threadedly connected to a threaded sleeve 10. The threaded sleeve 10 is fixedly connected to the inside of the installation disc 6. Below the installation disc 6, a stirring assembly 12 is arranged. The design of the stirring assembly 12 takes into account the requirements of easy maintenance and cleaning, facilitating the cleaning and disinfection work after stirring to ensure the hygienic quality of the next production. At the lower end of the front side of the column 2, a clamping assembly 11 is arranged. Due to the design of the clamping assembly 11 having a certain adjustment range, it can adapt to material containers of different sizes and shapes, enhancing the versatility and flexibility of the mixing device.

[0021] Preferably, the clamping assembly 11 includes an installation housing 1101. The rear side surface of the installation housing 1101 is fixedly connected to the front side surface of the column 2. At the middle position inside the installation housing 1101, a bidirectional motor 1102 is fixedly installed. The output ends on both sides of the bidirectional motor 1102 are fixedly connected to second threaded rods 1103. By driving the two second threaded rods 1103 by the bidirectional motor 1102, the two threaded blocks 1104 can move towards the center or away from each other simultaneously, realizing fast and precise clamping and releasing actions, improving work efficiency and operation convenience. Adopting a threaded connection method makes the clamping rod 1105 move more smoothly during the movement, avoiding the risk of insecure clamping or damage to the material container caused by sliding or shaking.

[0022] Specifically, the surfaces of the two second threaded rods 1103 are both threadedly connected to threaded blocks 1104. The front ends of the two threaded blocks 1104 are fixedly connected to clamping rods 1105. The inner sides of the ends of the two clamping rods 1105 are fixedly connected to rubber blocks 1106. The rubber blocks 1106 provide a good buffering effect, not only effectively preventing the rigid impact on the material container during clamping, but also increasing the friction during the clamping process, improving the stability and safety of clamping.

[0023] Specifically, the stirring assembly 12 includes a stirring motor 1201, which is fixedly installed at the rear side of the upper surface of the mounting plate 6. The output end of the stirring motor 1201 penetrates through the upper top plate of the mounting plate 6 and is fixedly connected with a first belt pulley 1202 inside the mounting plate 6. The stable connection between the stirring assembly 12, the mounting plate 6, and the rotating sleeve 1203 ensures the stability and reliability of the stirring rod 1204 during the stirring process. This structural design can withstand a large stirring force and extend the service life of the equipment.

[0024] Specifically, the stirring assembly 12 further includes a rotating sleeve 1203, which is fixedly connected to the front side of the mounting plate 6. A stirring rod 1204 is rotatably connected inside the rotating sleeve 1203.

[0025] Preferably, the upper end of the stirring rod 1204 is fixedly connected with a second belt pulley 1205. The second belt pulley 1205 is drivingly connected with the first belt pulley 1202 through a transmission belt 1207. The stirring motor 1201 drives the stirring rod 1204 to rotate through the transmission belt 1207 between the first belt pulley 1202 and the second belt pulley 1205. This belt drive method has the advantages of stable transmission, low noise, and high transmission efficiency, which can ensure the stirring effect while reducing energy consumption and noise pollution.

[0026] Specifically, the lower end of the stirring rod 1204 is fixedly connected with a stirring frame 1206. A plurality of stirring blades are fixedly connected to the surface of the stirring frame 1206. The stirring frame 1206 and the stirring blades on its surface are reasonably designed, which can fully stir the liquid polymer material, ensure the uniform mixing of the material, and improve the product quality. At the same time, the design of the stirring frame 1206 also helps to prevent the material from splashing during the stirring process and keep the working environment clean.

[0027] Working principle: When in use, first place the stirring barrel on the upper surface of the bottom plate 1. Then, the bidirectional motor 1102 drives the second threaded rods 1103 on both sides to rotate. Through the threaded cooperation with the threaded blocks 1104, the clamping rods 1105 on both sides move relatively, so that the rubber blocks 1106 clamp the stirring barrel. Then, the lifting motor 8 drives the first threaded rod 9 to rotate. Through the threaded sleeve 10, the mounting plate 6 moves along the length direction of the guide rod 7, and then drives the stirring frame 1206 in the stirring assembly 12 to enter the inside of the stirring barrel. After that, the output end of the stirring motor 1201 drives the first belt pulley 1202 to rotate, drives the second belt pulley 1205 to rotate through the transmission belt 1207, and the second belt pulley 1205 drives the stirring rod 1204 to rotate, so that the stirring frame 1206 rotates to stir and mix the raw materials inside the stirring barrel. After the stirring is completed, the output end of the lifting motor 8 reverses, and then drives the mounting plate 6 to move upward through the first threaded rod 9 and the threaded sleeve 10 to take out the stirring frame 1206.

[0028] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present utility model.
