Description
Technical Field
[0001] This utility model relates to the field of glass spray paint mixing technology, specifically to a convenient glass spray paint mixing device. Background Technology
[0002] Glass is an amorphous inorganic non-metallic material, generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, with the addition of small amounts of auxiliary materials. In glass processing, various colored glass paints are evenly sprayed onto the glass surface and then dried at high temperature to obtain painted glass of the desired color. Before using the glass paint, a color-mixing process is required, which necessitates the use of specialized pigment mixing equipment. The existing technology has the following problems:
[0003] When painting glass, the paint may settle in the paint bucket for an extended period, leading to sedimentation. Traditional mechanical agitators cannot effectively separate the paint into layers, resulting in insufficient mixing and poor mixing quality. Furthermore, existing paint mixing devices typically use rollers at the bottom for movement, but the small contact area between the rollers and the ground during mixing causes the mixing bucket to shake, further affecting the mixing effect.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0015] 1. This utility model provides a convenient glass spray paint mixing device, which employs a mixing tank, a fixed support ring, a U-shaped frame plate, an annular sleeve, a scraping mechanism, a driving mechanism, and a mixing mechanism in coordination. By controlling the driving mechanism to rotate the scraping mechanism and the mixing mechanism respectively, the mixing mechanism can stir the glass paint in the mixing tank in layers, while the scraping mechanism scrapes the glass paint off the inner wall of the mixing tank to prevent adhesion. This solves the problem that when glass paint is left in the paint tank for a long time, sediment will form. Traditional mechanical stirring cannot stir in layers, resulting in insufficient stirring and poor stirring effect. This device achieves the beneficial effect of ensuring sufficient stirring of glass paint and improving the stirring effect.
[0016] 2. This utility model provides a convenient glass paint mixing device. It employs a combination of a fixed support ring, a lifting mechanism, and a guide rail. When mixing glass paint, the lifting mechanism moves the bottom casters upwards, bringing the bottom of the mixing drum into contact with the ground. This increases the contact area and ensures mixing stability. This solves the problem that existing paint mixing devices typically use rollers at the bottom for movement, but the small contact area between the rollers and the ground during mixing causes the mixing drum to wobble, affecting the mixing effect. The new device achieves the beneficial effect of using the casters for lifting and lowering, facilitating the movement of the device while ensuring mixing stability. Attached Figure Description

The slider 87 slides along the guide rail 9, which has the effect of limiting the movement trajectory of the arc plate 83.
[0030] The working principle of this portable glass spray paint mixing device will be explained in detail below.
[0031] like Figure 1-5 As shown, when using this mixing device to mix glass paint, firstly, the mixing tank 1 is moved to the spraying position using the casters 86. Then, the connecting wires in the control panel 10 are connected to an external power source to provide power to stepper motor 61 and stepper motor 81. Then, the control panel 10 is operated to start stepper motor 81. The output shaft of stepper motor 81 drives the lead screw 82 to rotate, causing the moving block 84 to move the arc plate 83 upward. This causes the slider 87 on the inner wall of the arc plate 83 to slide upward along the inside of the guide rail 9, thereby detaching the casters 86 from the ground. This causes the bottom of the mixing tank 1 to contact and adhere to the ground, increasing the contact area with the ground and ensuring the stability of the mixing. Subsequently, the control panel 10 is operated to start stepper motor 61. 61. The output shaft of stepper motor 61 drives gear 63 to rotate via rotating rod 62, causing the gear 63 to rotate. The gear 63 drives the annular plate 51 and driven gear 73 to rotate. Driven gear 73 drives connecting rod 71 to rotate, causing stirring blades 75, 76 and 77 installed on connecting rod 71 to stir the glass paint in the mixing tank 1 in layers, so that the glass paint is fully and evenly stirred. At the same time, the outer wall of the annular plate 51 slides along the inside of the annular groove 401 via annular slider 53, causing scraper 56 on mounting plate 55 to scrape off the glass paint adhering to the inner wall of mixing tank 1, preventing adhesion. After stirring is completed, the glass paint in mixing tank 1 can be discharged by opening discharge valve 12.
[0032] The specific types and structures of the stepper motor 61, stepper motor 81, and discharge valve 12 used are all existing products. The specific circuit connection structure and control relationship between the control panel 10 and the stepper motor 61 and stepper motor 81 are also existing technologies, and will not be elaborated on here.
[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
