Description

Technical Field

[0001] This utility model relates to a bidirectional countercurrent stirring mechanism for polymer coatings. Background Technology

[0002] Polymer coatings, as a widely used material in industrial fields, require efficient and uniform stirring during production to ensure optimal viscosity, dispersibility, and stability. Traditional polymer coating stirring mechanisms typically employ a unidirectional stirring design, relying on a single-shaft impeller rotating and mixing materials within a tank. While simple, this structure has several shortcomings in practical applications. For example, unidirectional stirring cannot create effective countercurrent mixing, leading to uneven distribution of coating components and affecting product quality. Furthermore, the stirring components are fixedly connected to the tank, requiring disassembly of the entire device for maintenance and cleaning, which is time-consuming, labor-intensive, and significantly prolongs downtime, reducing production efficiency. Therefore, this invention proposes a bidirectional countercurrent stirring mechanism for polymer coatings to address these problems. Utility Model Content

[0009] As an improvement to the above technical solution, the bottom end of the supporting circular plate is provided with two sets of stirring rods, and the two sets of stirring rods are respectively connected to two sets of driven gears. The rotation of the driven gears drives the stirring rods to rotate. An installation plate is provided between the two sets of stirring rods, and the stirring rods are rotatably mounted on the installation plate.

[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. 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. Example

[0016] like Figure 1-11 As shown, this embodiment proposes a bidirectional countercurrent stirring mechanism for polymer coatings, including a stirring tank 10, with feeding pipes 11 communicating with the inner cavity on both sides of the stirring tank 10, and a stirring annular plate 12 on the stirring tank 10. A supporting circular plate 20 is provided on the stirring annular plate 12, a stirring assembly 40 is provided on the supporting circular plate 20, a stirring annular sleeve 14 is provided on the stirring annular plate 12, and a supporting annular plate 21 is provided on the supporting circular plate 20. The supporting annular plate 21 and the stirring annular sleeve 14 cooperate with each other so that the stirring assembly 40 extends into the inner cavity of the stirring tank 10.

[0017] In this embodiment, when stirring the polymer coating during production, the supporting ring plate 21 is aligned with the stirring ring sleeve 14, and the stirring assembly 40 extends into the inner cavity of the stirring tank 10 through the cooperation between the supporting ring plate 21 and the stirring ring sleeve 14. Then, the material is introduced into the inner cavity of the stirring tank 10 through the feed pipe 11, and then the stirring assembly 40 stirs the material. When the stirring assembly 40 needs maintenance, the supporting ring plate 21 is pulled out from the stirring ring sleeve 14, thereby pulling the stirring assembly 40 out of the stirring tank 10, completing the separation process of the stirring tank 10 and the stirring assembly 40, and then the stirring assembly 40 can be maintained. Through the cooperative design of the supporting annular plate 21 and the stirring annular sleeve 14, the stirring assembly 40 and the stirring tank 10 can be quickly separated and assembled. This structure significantly improves the ease of maintenance of the equipment: when it is necessary to clean, repair or replace the stirring assembly 40, the stirring assembly 40 can be moved out of the inner cavity of the stirring tank 10 simply by pulling out the supporting annular plate 21, which greatly shortens the downtime for maintenance and reduces the intensity of manual operation.

[0018] Specifically, the inner wall of the stirring annular sleeve 14 is provided with an internal threaded wall 13, and the outer wall of the supporting annular plate 21 is provided with an external threaded wall 22. The inner threaded wall 13 is adapted to the outer threaded wall 22, and the outer threaded wall 22 is threadedly engaged with the inner threaded wall 13, so that the supporting annular plate 21 is placed in the stirring annular sleeve 14.

[0019] In this embodiment, the supporting annular plate 21 can be reliably screwed into and positioned in the stirring annular sleeve 14 through the threaded engagement of the inner threaded wall 13 and the outer threaded wall 22, thereby achieving a detachable connection between the stirring assembly 40 and the stirring tank 10. This connection method facilitates the installation, disassembly, and maintenance of the stirring assembly 40.

[0020] Specifically, a sealing annular groove 23 is provided at the bottom end of the supporting circular plate 20, and a sealing gasket is provided in the sealing annular groove 23; The supporting annular plate 21 is placed in the stirring annular sleeve 14, so that the sealing gasket contacts the stirring annular plate 12 for sealing.

[0021] In this embodiment, when the supporting annular plate 21 is fully screwed into the stirring annular sleeve 14 through threaded engagement, the sealing annular groove 23 at the bottom of the supporting circular plate 20 and its internal sealing gasket tightly adhere to the upper surface of the stirring annular plate 12 under axial pressure, forming a continuous and uniform annular sealing interface. This effectively blocks the communication channel between the inner cavity of the stirring tank 10 and the external environment, preventing leakage or splashing of the polymer coating due to pressure or vibration during the stirring process.

[0022] Specifically, a support plate 30 is provided on the support circular plate 20, and a reinforcing plate 31 is provided at both ends of the support plate 30. The two sets of reinforcing plates 31 are respectively connected to the support circular plate 20. The stirring assembly 40 is mounted on the support plate 30.

[0023] In this embodiment, the support plate 30 facilitates the rotation of the support circular plate 20.

[0024] Specifically, the stirring assembly 40 includes a driving gear 45, and two sets of driven gears 44 are arranged on both sides of the driving gear 45, the driven gears 44 meshing with the driving gear 45; The two sets of driven gears 44 are symmetrically arranged, and the driving gear 45 and driven gears 44 are rotatably mounted on the support circular plate 20.

[0025] Specifically, the bottom end of the supporting circular plate 20 is provided with two sets of stirring rods 41, and the two sets of stirring rods 41 are respectively connected to two sets of driven gears 44. The rotation of the driven gears 44 drives the stirring rods 41 to rotate. An installation plate 50 is provided between the two sets of stirring rods 41. The stirring rods 41 are rotatably mounted on the installation plate 50, and a stirring guide plate 42 is provided on the stirring rods 41.

[0026] In this embodiment, when the raw materials of the polymer coating are stirred, the drive gear 45 rotates, thereby driving the two sets of driven gears 44 to rotate, which in turn drives the two sets of stirring rods 41 to rotate, so that the stirring plate 42 rotates in the stirring tank 10 to stir the raw materials.

[0027] Specifically, the stirring plate 42 is provided with two sets of stirring sleeves 421, and the two sets of stirring sleeves 421 are fixedly sleeved on the outer wall of the stirring rod 41; Two sets of stirring plates 42 are staggered in the inner cavity of the stirring tank 10. A drive motor 43 is provided on the support plate 30, and the drive motor 43 is connected to the drive gear 45.

[0028] In this embodiment, the drive motor 43 can easily drive the drive gear 45 to rotate. Of course, since the two stirring plates 42 are staggered, they do not need to interact during the rotation of the two stirring plates 42, so as to improve the stability of stirring.

[0029] Specifically, the mixing tank 10 is provided with a reinforcing plate 15, and the reinforcing plate 15 is provided with reinforcing holes 16; The mounting plate 50 is provided with a mounting rod 51, which is matched with the reinforcing hole 16. The stirring assembly 40 extends into the inner cavity of the stirring tank 10, so that the mounting rod 51 extends into the reinforcing hole 16.

[0030] In this embodiment, by extending the mounting rod 51 into the reinforcing hole 16, the stability of the mounting plate 50 can be effectively improved, thereby improving the overall stability of the stirring assembly 40 during the stirring process.

[0031] 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.
