Description

Technical Field

[0001] This utility model relates to the field of thermosetting powder coating technology, specifically to a thermosetting powder coating production mixing mechanism. Background Technology

[0002] Thermosetting powder coatings are widely used in modern industry, and the mixing process is crucial in their production. The uniformity of the mixing directly affects the quality and performance of the coating, and thus the quality of the final product.

[0003] Currently, common mixing mechanisms for thermosetting powder coatings typically employ a stirring method within a drum. The specific operation involves placing various coating raw materials into the drum, where mixing is achieved through the operation of a stirring device. However, this traditional mixing mechanism has significant drawbacks. After mixing, the material inside the drum needs to be emptied and discharged, usually by pouring or using a bottom discharge pipe. For example, CN221752969U discloses a mixing mechanism for thermosetting powder coatings, but this material discharge process is time-consuming, severely impacting production efficiency. During the material cleaning process, the next round of mixing cannot proceed; it must wait until cleaning is complete and all material has been discharged before the next mixing operation can begin, resulting in shortened effective operating time and low overall production efficiency.

[0004] With the increasing demands for efficiency and capacity in industrial production, there is an urgent need to develop a new type of mixing mechanism to solve the problem of low material discharge efficiency and improve the production efficiency of thermosetting powder coatings. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a mixing mechanism for thermosetting powder coating production, which solves the problem of low material discharge efficiency and improves the production efficiency of thermosetting powder coatings.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a thermosetting powder coating production mixing mechanism, comprising an outer cylinder with an opening at the top and a drive motor installed at the bottom. A detachable inner cylinder is installed inside the outer cylinder, and a connecting shaft is rotatably mounted in the middle of the inner cylinder. A stirring blade is mounted on the connecting shaft, and the bottom of the connecting shaft penetrates the bottom wall of the inner cylinder. A first connector is mounted on the connecting shaft, and a second connector is mounted on the rotating end of the drive motor. The first and second connectors are matched and connected by a plug-in method. When the first and second connectors are plugged together, the drive motor drives the second connector to rotate, which synchronously drives the stirring blade on the connecting shaft to rotate.

[0009] Furthermore, a protruding positioning block is provided on the inner wall of the bottom of the outer cylinder, and several positioning grooves matching the positioning block are opened on the outer wall of the bottom of the outer cylinder. The positioning block is inserted into the positioning groove to prevent the inner cylinder from rotating inside the outer cylinder.

[0010] Furthermore, a cover is installed at the opening of the inner cylinder.

[0011] Furthermore, a handle is installed on the inner cylinder.

[0012] Furthermore, the handle is hinged to the inner cylinder, and the handle can be flipped at multiple angles.

[0013] Furthermore, a support frame is provided on the outside of the outer cylinder.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a mixing mechanism for the production of thermosetting powder coatings, which has the following beneficial effects:

[0016] This thermosetting powder coating production mixing mechanism features a detachable inner cylinder installed inside an outer cylinder. The connecting shaft is connected to a drive motor via connectors one and two. Therefore, during operation, multiple replaceable inner cylinders can be used. While mixing in the current inner cylinder, workers can simultaneously add and prepare materials in other inner cylinders. After mixing, the inner cylinder filled with the mixed coating can be quickly removed and emptied. A new inner cylinder with prepared materials can then be inserted to begin a new round of mixing. No cleaning or refilling is required. The removal of the inner cylinder and the installation of a new one can be completed in a very short time, significantly reducing the connection time between mixing processes and greatly improving production efficiency.

[0024] 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.

[0025] Please see Figure 1-6 This utility model discloses a thermosetting powder coating production mixing mechanism, including an outer cylinder 1, a support frame 2 on the outside of the outer cylinder 1, an opening at the top of the outer cylinder 1, a drive motor 3 installed at the bottom of the outer cylinder 1, a detachable inner cylinder 4 installed inside the outer cylinder 1, a connecting shaft 5 rotatably installed in the middle of the inner cylinder 4, a stirring blade 6 on the connecting shaft 5, the bottom of the connecting shaft 5 penetrating the bottom wall of the inner cylinder 4, a first connector 7 on the connecting shaft 5, and a second connector 8 on the rotating end of the drive motor 3. The first connector 7 and the second connector 8 are matched with each other and connected by a plug-in method. When the first connector 7 and the second connector 8 are plugged together, the drive motor 3 drives the second connector 8 to rotate, which synchronously drives the stirring blade 6 on the connecting shaft 5 to rotate.

[0026] The first connector 7 on the connecting shaft 5 adopts a polygonal slot structure, while the second connector 8 at the rotating end of the drive motor 3 is designed as a regular polygonal insert. When the insert is inserted into the slot, the two fit tightly together and can achieve synchronous rotation.

[0027] The polygonal design increases the contact area between the insert and the slot during rotation, resulting in more uniform and stable torque transmission. This ensures that the mixing blade 6 can stably and efficiently mix the coating. Conversely, the design can also be reversed: the connector 7 on the connecting shaft 5 can be a regular polygonal insert, while the connector 8 at the rotating end of the drive motor 3 can be a polygonal slot. This reverse arrangement also achieves a tight fit and synchronous rotation, providing reliable assurance for the stable operation of the mixing mechanism and meeting the needs of different production scenarios and equipment installation.

[0028] A protruding positioning block 10 is provided on the inner wall of the bottom of the outer cylinder 1, and several positioning grooves 9 that match the positioning block 10 are provided on the outer wall of the bottom of the outer cylinder 1. The positioning block 10 is inserted into the positioning groove 9 to prevent the inner cylinder 4 from rotating inside the outer cylinder 1. The reverse design is also possible.

[0029] Alternatively, the outer wall of the inner cylinder 4 can be designed as a polygon, and a matching polygon can be provided on the inner wall of the outer cylinder 1. When the inner cylinder 4 is placed inside the outer cylinder 1, the polygonal fitting structure can effectively prevent the inner cylinder 4 from rotating inside the outer cylinder 1 during the mixing process.

[0030] A cover 12 is installed at the opening of the inner cylinder 4 to prevent paint from spilling out of the opening of the inner cylinder 4. A handle 11 is installed on the inner cylinder 4 to facilitate the worker to lift the inner cylinder out of the outer cylinder. The handle 11 is hinged to the inner cylinder 4 and can be rotated at multiple angles to facilitate the worker to pour out the paint in the inner cylinder.

[0031] In summary, this thermosetting powder coating production mixing mechanism, during use, requires the various raw materials needed for the thermosetting powder coating to be accurately prepared in advance according to the formula in multiple inner cylinders 4. The inner cylinder 4 with the prepared coating is carefully placed into the outer cylinder 1, ensuring that the inner cylinder 4 is properly installed and will not rotate during the mixing process. The connecting part 7 on the connecting shaft 5 is aligned with the connecting part 8 on the rotating end of the drive motor 3 and inserted to ensure a tight connection, guaranteeing that the drive motor 3 can effectively drive the connecting shaft 5 to rotate. The power supply to the drive motor 3 is then turned on, and the drive motor 3 is started. After the drive motor 3 starts running, its rotating end drives the connecting part 8 to rotate, which in turn synchronously drives the connecting shaft 5 and the stirring blade 6 on the connecting shaft 5 to rotate at high speed. The stirring blade 6 thoroughly mixes the coating in the inner cylinder 4. During the mixing process, the speed of the drive motor and the mixing time can be controlled according to the characteristics of the coating and the mixing requirements. After the mixing operation of the inner cylinder 4 is completed, the mixed inner cylinder 4 is taken out from the outer cylinder 1. Then, the next inner cylinder 4 containing the coating to be mixed is put into the outer cylinder 1 for mixing. Then, the mixed inner cylinder 4 is poured out, and a new round of mixing can be started immediately, realizing continuous production and improving processing efficiency.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
