Description

Technical Field

[0001] This utility model relates to the field of coating production technology, specifically a quantitative proportioning device for the production of liquid epoxy coatings. Background Technology

[0002] Waterborne epoxy resins can be divided into anionic and cationic resins. Anionic resins are used in anodic electrodeposition coatings, while cationic resins are used in cathodic electrodeposition coatings. The main characteristic of waterborne epoxy resins is their excellent anti-corrosion performance. In addition to automotive coatings, they are also used in medical devices, electrical appliances, and light industrial products. Coatings are usually made by mixing various raw materials. To ensure the quality of coatings, the amount and ratio of various raw materials used in the coating process must be strictly controlled in order to produce high-quality coatings.

[0003] A search revealed, for example, a utility model patent with Chinese publication number CN220003866U, which discloses a quantitative mixing device for paint manufacturing. This device, through the cooperation of a material cylinder and a conveying pipe, allows raw materials to fall in small amounts from the conveying pipe, ensuring the effect of dispersing the raw materials. Through the cooperation of a motor, a material box, a rotating plate, a pusher plate, and a drain hole, the motor's operation allows the rotating plate to disperse the falling raw materials. During the dispersion process, the raw materials mix together, while the pusher plate pushes the raw materials, allowing them to fall downwards through the drain hole, preventing the raw materials from accumulating. The stirring rod then mixes them evenly, ensuring the quality of the produced paint.

[0004] However, this device only uses a single stirring rod during mixing, resulting in a mediocre mixing effect. Therefore, a quantitative proportioning device for the production of liquid epoxy coatings was proposed to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a quantitative proportioning device for the production of liquid epoxy coatings, which has advantages such as facilitating improved coating mixing effects and solving the problem of mediocre mixing effects when using comparative proportioning devices.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a quantitative proportioning device for the production of liquid epoxy coatings, comprising a raw material tank, two mixing tanks installed on the top of the raw material tank, a feed pipe fixedly installed on the bottom of the mixing tank, a bottom plate provided at the bottom of the raw material tank, and a stirring mechanism provided on the raw material tank;

[0009] The stirring mechanism includes a turbine. The turbine is fixedly sleeved on the outside of the raw material tank. Two mounting plates are fixedly installed on the top of the bottom plate. A worm gear is rotatably connected between the two mounting plates. A first motor is fixedly installed on the side wall of one of the mounting plates. A first housing is fixedly installed on the top of the raw material tank. A second motor is fixedly installed on the front side of the first housing.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] 1. This quantitative proportioning device for the production of liquid epoxy coatings, by setting up a stirring mechanism, can rotate the raw material tank itself through the cooperation of a turbine and a worm gear, or drive two gears to rotate by controlling a second motor, causing the gears to drive two stirring rods to shake.

Detailed Implementation

[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 1-4 A quantitative proportioning device for producing liquid epoxy coatings in this embodiment includes a raw material tank 1, two mixing tanks 2 are installed on the top of the raw material tank 1, a feed pipe 3 is fixedly installed on the bottom of the mixing tank 2, a bottom plate 4 is provided at the bottom of the raw material tank 1, and a stirring mechanism 5 is provided on the raw material tank 1.

[0026] Specifically, the stirring mechanism 5 includes a turbine 501. The turbine 501 is fixedly sleeved on the outside of the raw material tank 1. Two mounting plates 502 are fixedly installed on the top of the base plate 4. A worm gear 503 is rotatably connected between the two mounting plates 502. A first motor 504 is fixedly installed on the side wall of one of the mounting plates 502. A first housing 505 is fixedly installed on the top of the raw material tank 1. A second motor 506 is fixedly installed on the front side of the first housing 505. A rotating rod 507 is rotatably connected inside the first housing 505. A gear 508 is installed on the outside of the rotating rod 507. A connecting shaft 509 is fixedly installed on the outside of the gear 508. The connecting shaft 509 rotates externally. A connecting plate 510 is connected, and a stirring rod 511 is fixedly installed on the outside of the connecting plate 510. The ends of the two connecting plates 510 away from the connecting shaft 509 are rotatably connected to a rotating shaft 512. By setting the stirring mechanism 5, when mixing the mixture inside the raw material tank 1, the raw material tank 1 can rotate by the cooperation of the turbine 501 and the worm gear 503, or the second motor 506 can be controlled to drive the two gears 508 to mesh and rotate, so that the gears 508 drive the two stirring rods 511 to shake. The two stirring rods 511 alternately stir in a circular motion inside the raw material tank 1, and the internal and external mixing can achieve a better stirring effect.

[0027] Furthermore, as the two gears 508 rotate, the connecting shaft 509 will also change continuously. The connecting shaft 509 drives the connecting plate 510 to move, and the two connecting plates 510 will open and close and move up and down. The stirring rod 511 will move accordingly to stir and mix.

[0028] Specifically, the first housing 505 is connected to the interior of the second housing 6 through an opening. A groove is provided on the rear inner wall of the second housing 6, and a slider is slidably connected inside the groove. When the connecting plate 510 moves, it will push the slider to move up and down in the groove.

[0029] Specifically, the output shaft of the first motor 504 is fixedly connected to the worm gear 503, the turbine 501 is meshed with the worm gear 503, and a control valve is installed on the feed pipe 3. The control valve is an electronic control valve and is connected to an external PLC controller.

[0030] When implementing this procedure, please follow these steps:

[0031] 1) First, place the required amount of raw materials into the mixing tank 2. Then, control the valve to feed the raw materials from the mixing tank 2 in a fixed quantity. The raw materials fall into the raw material tank 1 for mixing.

[0032] 2) Then control the first motor 504 to drive the worm gear 503 to rotate, thereby driving the raw material tank 1 to rotate on the bottom plate 4;

[0033] 3) Finally, control the second motor 506 to drive the two gears 508 to mesh and rotate, so that the gears 508 drive the two stirring rods 511 to shake. The two stirring rods 511 alternately stir in circles inside the raw material tank 1, and mix and stir the inside and outside.

[0034] In summary, this quantitative proportioning device for liquid epoxy coating production, by setting up a stirring mechanism 5, can achieve better mixing results when mixing the mixture inside the raw material tank 1. This is possible through the cooperation of the turbine 501 and the worm gear 503, which rotates the raw material tank 1 itself, or by controlling the second motor 506 to drive the two gears 508 to mesh and rotate. The gears 508 drive the two stirring rods 511 to shake, and the two stirring rods 511 alternately stir in a circular motion inside the raw material tank 1. This combination of internal and external mixing achieves better mixing results and solves the problem that the proportioning device only uses a single stirring rod, resulting in a mediocre mixing effect.

[0035] Furthermore, this quantitative mixing device for the production of liquid epoxy coatings, by setting up two mixing tanks 2, allows the quantitative raw materials to be mixed to be placed into the mixing tanks 2, and the raw materials in the mixing tanks 2 are quantitatively fed out by controlling the valve.
