Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing equipment technology, and in particular to a mixing device for coatings. Background Technology
[0002] Paint mixing is a crucial step in paint production and application. Its purpose is to uniformly mix the various components of the paint to achieve the desired viscosity and texture for easy application. In existing technologies, paint mixing typically involves a motor driving a mixing element to rotate, causing the paint particles to move and collide, thereby achieving mixing.
[0003] Chinese Patent CN115970534B discloses a stirring device and method for preparing fire-retardant coatings. The stirring device includes a stirring cylinder and a rotation drive. The stirring cylinder contains a scraper, a first stirring element, and a second stirring element. A cleaning blade is provided on a sliding component, and both the first and second stirring elements have comb teeth. The device drives the scraper, first stirring element, and second stirring element to rotate within the stirring cylinder to mix the coating. By driving the first and second stirring elements to rotate in opposite directions, they scrape off coating adhering to each other's comb teeth. Simultaneously, the device also removes coating adhering to the scraper by sliding the cleaning blade on its surface.
[0004] However, the above patent still has the following problems: as the stirring time increases, the coating will become thicker and thicker, which will hinder the shearing force of the stirring component and lead to a decrease in stirring efficiency. Utility Model Content

[0012] Beneficial effects

[0022] Example
[0023] like Figures 1-4As shown, this utility model provides a stirring device for coatings, including a housing 1 and a stirring shaft 2 disposed within the housing 1. The device is characterized by: a drive motor 201 fixedly connected to the top of the housing 1; the output shaft of the drive motor 201 fixedly connected to the stirring shaft 2; multiple connecting shafts 202 disposed on the outer peripheral wall of the stirring shaft 2; each connecting shaft 202 being provided with a stirring blade 203; a protective sleeve 204 fixedly connected to the bottom of the stirring shaft 2; and a rotating assembly disposed inside the protective sleeve 204, the rotating assembly including a rotating electric motor fixedly disposed within the protective sleeve 204. Machine 206, a drive shaft 207 is fixedly connected to the output shaft of the rotary motor 206, the drive shaft 207 is inserted into the stirring shaft 2, a plurality of first bevel gears 208 are fixedly connected to the drive shaft 207, and a second bevel gear 209 is snapped to the end of the connecting shaft 202, the second bevel gear 209 meshes with the first bevel gear 208, a bidirectional electric telescopic rod 210 is also fixedly connected to the inner peripheral wall of the protective sleeve 204, a connecting plate 211 is fixedly connected to both sides of the bidirectional electric telescopic rod 210, and a clamping plate 212 is fixedly connected to the connecting plate 211.
[0024] Specifically: the drive motor 201 drives the stirring shaft 2 and the stirring blade 203 to rotate, thereby achieving the stirring effect on the coating, and the stirring shaft 2 and the protective sleeve 204 rotate synchronously;
[0025] When it is necessary to change the angle of the stirring blade 203, the bidirectional electric telescopic rod 210 controls the two clamping plates 212 to move away from the output shaft of the rotary motor 206, thereby releasing the restriction on the output shaft of the rotary motor 206. The rotary motor 206 drives the transmission shaft 207 to rotate. The transmission shaft 207 drives multiple connecting shafts 202 and the stirring blade 203 to rotate through the meshing effect of the first bevel gear 208 and the second bevel gear 209, thereby changing the angle of the stirring blade 203. When the stirring blade 203 rotates to the specified angle, the rotary motor 206 stops, and the two clamping plates 212 limit the output shaft of the rotary motor 206, thereby restricting the rotation of the transmission shaft 207 and stabilizing the angle of the connecting shaft 202 and the stirring blade 203.
[0026] It is understandable that when stirring begins, the angle between the stirring blade 203 and the horizontal direction is at its maximum, preferably 60°. At this time, the stirring shaft 2 drives the stirring blade 203 to rotate at high speed, and the larger pushing surface can improve the stirring effect. As the coating concentration increases, the angle between the stirring blade 203 and the horizontal direction is reduced, the liquid cutting force of the stirring blade 203 is increased, and the stirring effect is improved. That is, the angle of the stirring blade 203 is adjusted in time according to the coating concentration to adapt to the change of coating concentration and achieve a highly efficient stirring effect.
[0027] The top of the shell 1 is provided with a feed pipe 101, and the paint enters along the feed pipe 101. The bottom of the shell 1 is provided with a discharge pipe 102, and the stirred paint is discharged from the discharge pipe 102.
[0028] The clamping plate 212 has multiple grooves 213, and the output shaft of the rotary motor 206 has multiple protrusions 205. The clamping force of the clamping plate 212 on the output shaft of the rotary motor 206 is enhanced by the arrangement of the grooves 213 and the protrusions 205.
[0029] The working principle of this utility model is as follows: the drive motor 201 drives the stirring shaft 2 and the stirring blade 203 to rotate, thereby achieving the stirring effect on the coating. The stirring shaft 2 and the protective sleeve 204 rotate synchronously.
[0030] When it is necessary to change the angle of the stirring blade 203, the bidirectional electric telescopic rod 210 controls the two clamping plates 212 to move away from the output shaft of the rotary motor 206, thereby releasing the restriction on the output shaft of the rotary motor 206. The rotary motor 206 drives the transmission shaft 207 to rotate. Through the meshing effect of the first bevel gear 208 and the second bevel gear 209, the transmission shaft 207 drives multiple connecting shafts 202 and the stirring blade 203 to rotate, thereby changing the angle of the stirring blade 203. When the stirring blade 203 rotates to the specified angle, the rotary motor 206 stops, and the two clamping plates 212 limit the output shaft of the rotary motor 206, thereby restricting the rotation of the transmission shaft 207 and stabilizing the angle of the connecting shaft 202 and the stirring blade 203.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[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.
