Description

Technical Field

[0001] This utility model belongs to the field of UV masterbatch processing technology, and more specifically, it relates to a mixing device for UV masterbatch anti-ultraviolet processing. Background Technology

[0002] UV masterbatch anti-ultraviolet processing is a key production process that scientifically mixes various raw materials to give plastic products the ability to resist ultraviolet rays. In order to ensure that the UV masterbatch has stable and efficient anti-ultraviolet performance and ensure that the UV absorbers, light stabilizers and other additives are evenly dispersed, a mixing device is required.

[0003] However, traditional mixing devices typically employ a single stirring method with a fixed mixing tank position. This can easily lead to dead zones during the stirring process, resulting in uneven mixing of raw materials. Consequently, some UV masterbatches may lack sufficient UV resistance, affecting the final UV resistance effect of the UV masterbatches and shortening the product's lifespan. Utility Model Content

[0005] The purpose and effect of this utility model's mixing device for UV masterbatch anti-ultraviolet processing are achieved by the following specific technical means:

[0006] A mixing device for UV masterbatch anti-ultraviolet processing includes a support base and a rotating rod. Multiple sets of support rods are mounted on the support base, and each support rod has a first bearing. Both ends of the rotating rod pass through the first bearings, and the rotating rod is rotatably connected to the support rods. A driving unit is located above the support base and is connected to one end of the rotating rod. Multiple mixing components are also located above the support base. Each mixing component includes a mixing tank and a cover plate, which are connected to form a stirring chamber. A stirring element is disposed within the stirring chamber.

[0007] According to a preferred embodiment, multiple sets of mounting frames are provided at both ends of the rotating rod. The multiple sets of mounting frames at the same end are arranged in a circle, and the multiple sets of mounting frames at both ends are symmetrically distributed. The mixing tank is respectively inserted into two sets of symmetrical mounting frames at both ends. Multiple sets of mounting holes are provided on both the mounting frames and the mixing tank, and mounting bolts are inserted into the mounting holes.

[0008] According to a preferred embodiment, a plurality of electric cylinders are provided above the support base. The electric cylinders are located below the mounting frame. A support block is provided at the shaft end of the electric cylinder. An arc-shaped groove is provided on the top of the support block. The arc of the arc-shaped groove is consistent with the arc of the mounting frame. The support block is in contact with the mounting frame.

[0009] According to a preferred embodiment, the stirring component includes a stirring rod, and both the mixing tank and the inner side of the cover plate are provided with mounting sleeves. A second bearing is provided inside the mounting sleeve, and both ends of the stirring rod are respectively inserted into the second bearing. A motor is provided on one side of the cover plate, and the motor shaft is connected to one end of the stirring rod. The stirring rod is provided with multiple sets of stirring blades, and the distances between the multiple sets of stirring blades and the inner wall of the mixing tank are not consistent, and they are arranged at different heights.

[0010] According to a preferred embodiment, a motor cover is provided on one side of the cover plate, and the motor cover is connected to the cover plate to form a motor cavity, and the motor is located in the motor cavity; multiple sets of heat-conducting plates are provided on the motor cover, and an infrared temperature sensor is provided on one set of the support rods, with the infrared temperature sensor facing the motor cover of one set of the mixing components.

[0011] According to a preferred embodiment, a plurality of air outlet pipes are provided above the support base, the air outlet pipes are installed on the support base, and the air outlet pipes are provided with air outlets facing upwards; a fan is installed on the support base, and the fan is connected to the plurality of air outlet pipes through connecting pipes.

[0012] According to a preferred embodiment, a plurality of mounting blocks are provided on one side of one of the support rods, and mounting slots are provided on the mounting blocks.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This device, through the arrangement of a rotating rod and multiple sets of mounting frames, places the mixing tank at both ends within symmetrically distributed and circumferentially arranged mounting frames. When the drive unit rotates the rotating rod, the mixing tank rotates accordingly, changing its position. Simultaneously, multiple sets of staggered stirring blades on the stirring rod, driven by a motor, work in conjunction with the rotation of the mixing tank to form a multi-dimensional stirring method. This structural design breaks away from the traditional single stirring mode, eliminates dead zones in the stirring, and allows various raw materials such as UV absorbers and light stabilizers to be fully and uniformly mixed within the stirring chamber. This improves the mixing quality of the UV masterbatch and ensures the stability of its UV resistance performance.

[0015] 2. The motor cover and heat-conducting plate on one side of the cover plate, together with the infrared temperature sensor on the support rod, can monitor the motor temperature in real time and dissipate heat in a timely manner through the heat-conducting plate. This effectively prevents the motor from overheating due to prolonged operation, which could affect its performance and lifespan, and ensures the continuous and stable operation of the mixing process. The electric cylinder and support block above the support base provide stable support when the mixing tank is working. The matching design of the arc groove and the mounting frame enhances the overall structural stability of the device. The combination of the air outlet duct and the fan can ventilate and dissipate heat during the mixing process, improving the working environment. The installation of electromagnets, limit plates, and magnetic plates facilitates precise limiting and control of the rotating rod, ensuring the reliability and safety of the device operation, extending the service life of the equipment, and reducing maintenance costs.

Detailed Implementation

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0023] Example:

[0024] like Figures 1 to 4 As shown, this utility model provides a mixing device for UV masterbatch anti-ultraviolet processing, including a support base 11 and a rotating rod 21, which cooperate to form the basic structure of the device. The support base 11 serves as the load-bearing foundation of the entire device, and multiple sets of support rods 12 are arranged on it, which play a supporting and positioning role. Each support rod 12 is provided with a first bearing, and both ends of the rotating rod 21 are respectively inserted into the first bearing, so that the rotating rod 21 can be rotatably connected to the support rod 12. This connection method provides flexible movement space for the rotation of the rotating rod 21, ensuring that the rotating rod 21 can rotate freely within a certain range. A drive unit is arranged on the support base 11, which is connected to one end of the rotating rod 21. The power generated by the drive unit can be transmitted to the rotating rod 21, driving the rotating rod 21 to rotate, thereby providing the necessary power source for the entire mixing process. Multiple mixing components are also arranged on the support base 11, including a mixing tank 31 and a cover plate 32, which are connected to form a stirring chamber, which is the main place for raw material mixing. The stirring components inside the mixing chamber are responsible for mixing the various raw materials entering the chamber. Through a specific movement pattern, the stirring components thoroughly mix the raw materials such as ultraviolet absorbers and light stabilizers, resulting in the final UV masterbatch having excellent UV resistance properties.

[0025] The rotating rod 21 plays a crucial role in the transmission and connection of the mixing device, with multiple sets of mounting frames 22 at both ends. The mounting frames 22 at the same end are arranged in a circular pattern, allowing the rotating rod 21 to transmit power more evenly to the mounting frames 22 during rotation. The symmetrical distribution of the mounting frames 22 at both ends ensures balance during rotation, preventing instability caused by uneven force. The mixing tank 31 is threaded through two sets of symmetrical mounting frames 22 at both ends, connecting the mixing tank 31 to the rotating rod 21. When the rotating rod 21 rotates, it drives the mixing tank 31 to rotate as well, changing its position in space and allowing the raw materials inside the mixing tank 31 to be stirred at different angles, effectively reducing dead zones in the mixing process. Both the mounting frame 22 and the mixing tank 31 have multiple sets of mounting holes, with mounting bolts inserted into the mounting holes. This connection method facilitates the installation and disassembly of the mixing tank 31, makes it easy to clean and maintain the mixing tank 31 after the mixing work is completed, and also makes it easy to replace the mixing tank 31 of different specifications according to different mixing needs.

[0026] Multiple sets of electric cylinders 13, located above the support base 11 and below the mounting frame 22, primarily support the mounting frame 22 and the mixing tank 31. Support blocks 14 at the shaft ends of the electric cylinders 13 can rise and fall with the extension and retraction of the electric cylinders 13. The top of the support block 14 has an arc-shaped groove whose curvature matches that of the mounting frame 22. When the mounting frame 22 rotates, the arc-shaped groove of the support block 14 remains in contact with the mounting frame 22, providing support without excessively restricting the rotation of the mounting frame 22, ensuring smooth rotation of the mounting frame 22 and the mixing tank 31 by the rotating rod 21. During operation of the mixing device, the electric cylinders 13 can adjust the height of the support blocks 14 according to actual needs, thereby fine-tuning the position of the mixing tank 31. This ensures the mixing tank 31 remains stable during rotation and mixing, preventing positional shifts from affecting the mixing effect, reducing wear caused by shaking, and extending the device's service life.

[0027] like Figure 2 , Figure 3 As shown, the mixing component includes a stirring rod 33. Both the mixing tank 31 and the cover plate 32 have mounting sleeves on their inner sides. A second bearing inside the mounting sleeve provides rotational support for the stirring rod 33. Both ends of the stirring rod 33 pass through the second bearings, allowing it to rotate freely within the mixing chamber formed by the mixing tank 31 and the cover plate 32. A motor 34 on one side of the cover plate 32 is connected to one end of the stirring rod 33 via its shaft. The motor 34 acts as a power source, transmitting power to the stirring rod 33 to drive it to rotate within the mixing chamber. Multiple sets of stirring blades 35 on the stirring rod 33 are components that directly act on the raw materials for mixing. The distances between these stirring blades 35 and the inner wall of the mixing tank 31 are not uniform, and they are set at different heights. This arrangement allows the stirring blades 35 at different heights to stir the raw materials at different positions in the mixing tank 31 when the stirring rod 33 rotates, thereby expanding the stirring coverage and allowing various raw materials such as ultraviolet absorbers and light stabilizers to be more fully mixed in the mixing chamber. This effectively reduces the mixing blind zone and improves the mixing quality of UV masterbatch.

[0028] The motor cover 36 on one side of the cover plate 32 is connected to the cover plate 32 to form a motor cavity. The motor 34 is placed inside the motor cavity. The motor cover 36 protects the motor 34 and prevents external debris from entering and affecting its operation. Multiple sets of heat-conducting plates 37 on the motor cover 36 can conduct away the heat generated by the motor 34 during operation, reducing the temperature of the motor 34. An infrared temperature sensor installed on one of the support rods 12 faces the motor cover 36 of one of the mixing components, enabling real-time monitoring of the temperature of the motor cover 36 and thus the temperature of the motor 34. If the motor 34 overheats, timely measures can be taken to ensure its normal operation and prevent the mixing process from being affected by motor 34 malfunction.

[0029] Multiple sets of air outlet pipes 41 are mounted on the support base 11, with the air outlets on the air outlet pipes 41 facing upwards. A fan 42 mounted on the support base 11 is connected to the multiple sets of air outlet pipes 41 via connecting pipes. When the fan 42 is working, it delivers air through the connecting pipes to the air outlet pipes 41 and blows it out from the air outlets. This blown air ventilates the mixing process, removing heat generated during mixing, lowering the temperature inside the mixing chamber, and preventing changes in the properties of the raw materials due to excessive temperature. Furthermore, ventilation improves the working environment, reducing the accumulation of odors and dust generated during mixing in the working area, providing a relatively good working environment for operators.

[0030] like Figure 4 As shown, multiple mounting blocks 15 on one side of one set of support rods 12 provide basic bearing and fixing points for the entire limiting structure. The mounting grooves 16 on these blocks allow the electromagnet 17 above the support base 11 to be stably installed, preventing it from easily shaking or shifting during device operation. The limiting plate 18 and magnetic suction plate 19 on the rotating rod 21 are key components for limiting and slowing down the rotating rod 21 in conjunction with the electromagnet 17. The magnetic suction plate 19 is located between the limiting plate 18 and the electromagnet 17, maintaining a certain gap to prevent wear on the electromagnet 17. When the mixing device is working, the electromagnet 17 is not energized and does not generate magnetism. At this time, the magnetic suction plate 19 maintains a gap with the electromagnet 17, and the limiting plate 18 is not subject to additional obstruction. This allows the rotating rod 21 to rotate freely under the drive of the drive unit without interference from the electromagnet 17, thereby smoothly driving the mixing tank 31 to complete the mixing work and ensuring that the raw materials are fully mixed in the mixing chamber. When mixing is complete and the rotating rod 21 needs to be stopped, the multiple mixing components mounted above it have a certain weight, causing the rod 21 to have inertia and be difficult to stop immediately. At this point, multiple electromagnets 17 come into play, generating magnetism one by one in a pre-set sequence. The first electromagnet 17 to generate magnetism attracts the magnetic plate 19, applying a reverse force to the rotating rod 21 and slowing its rotation. As other electromagnets 17 generate magnetism in sequence, an increasingly larger reverse force continuously acts on the rotating rod 21, gradually weakening its inertia and eventually causing it to stop slowly. This prevents the rotating rod 21 from over-rotating due to inertia, which could affect subsequent operation and maintenance of the mixing components, and also reduces the risk of damage to the equipment caused by sudden stops and starts.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
