Description

Technical Field

[0001] The utility model relates to the technical field of disk brushes, in particular to a disk brush structure. Background Technique

[0002] The main functions of the disk brush are as follows: the abrasive wire brush has the functions of grinding, finishing, polishing, and deburring; it is widely used in various industries, such as before the processing of cold-rolled plates and galvanized and tin-plated sheets and the post-treatment of the metal surface, and removing burrs and chamfers after machining. Since a single group of disk brushes is difficult to achieve a comprehensive cleaning effect, generally multiple groups of disk brushes are assembled for use. However, in the actual use process, multiple groups of disk brushes are generally driven by a transmission belt. This transmission method has a weak load-bearing capacity, a large wear on the transmission belt, and a short service life. In addition, the cleaning direction of the existing disk brushes is relatively single. When rotating, it can only clean the area within its own rotation radius, and there may be some corners that cannot be cleaned. For this reason, we propose a disk brush structure to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a disk brush structure to solve the problems of the existing transmission belt drive method with weak load-bearing capacity, large wear, and the relatively single cleaning direction and incomplete cleaning of the existing disk brushes as mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a disk brush structure, including a mounting disk, on which a gearbox is fixedly installed.

[0005] A main shaft is fixedly installed on the gearbox. A transmission shaft is rotatably installed in the main shaft. The transmission shaft is connected to the output shaft of the motor. Four groups of disk brushes are rotatably installed in an array on the lower side of the mounting disk. A main transmission gear, an idler gear, and an output shaft gear are rotatably installed in the mounting disk. The main transmission gear, the idler gear, and the output shaft gear are meshed with each other. The center of the output shaft gear is connected to the center position of the disk brush.

[0006] Preferably, a revolution transmission sprocket is fixedly installed at the lower end of the main shaft. There are two groups of revolution transmission sprockets with an obvious distance between them.

[0007] Preferably, the main transmission gear is fixedly installed at the lower end of the transmission shaft. Two groups of idler gears are meshed with the main transmission gear. Another group of idler gears is meshed with the idler gears. Four groups of idler gears are all meshed with the output shaft gear.

[0008] Preferably, the distances between the four groups of output shaft gears are equal, and the angles between the four groups of output shaft gears are all ninety degrees.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model replaces the belt drive with a gear drive, which enables the equipment to have a greater load-bearing capacity and a longer service life, thereby reducing the usage cost of the equipment. The four groups of disk brushes rotate forward and backward instead of rotating in the same direction before, resulting in a better grinding effect. Moreover, the structural volume of the equipment is reduced, the structure is concentrated and effective, saving materials and electricity. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0017] Please refer to Figures 1-4 , an embodiment provided by the present utility model: A disk brush structure includes a mounting disc 1, and a gear box 2 is fixedly installed on the mounting disc 1.

[0018] A main shaft 3 is fixedly installed on the gearbox 2. A transmission shaft 4 is rotatably installed inside the main shaft 3. The transmission shaft 4 is connected to the output shaft of the motor. Four sets of disk brushes 5 are rotatably installed in an array on the lower side of the mounting disk 1. A main transmission gear 7, an idle gear 8 and a power output shaft gear 9 are rotatably installed inside the mounting disk 1. The main transmission gear 7, the idle gear 8 and the power output shaft gear 9 are meshed with each other. The center of the power output shaft gear 9 is connected to the center position of the disk brush 5. The transmission of this equipment by gears instead of a transmission belt makes the bearing capacity of the equipment stronger and the service life longer. In addition, a planetary transmission sprocket 6 is provided so that the equipment can rotate self - rotatably, and cooperate with the rotation of the disk brush 5 to achieve a large - area effect, increasing the functionality of the equipment during use;

[0019] Further, a planetary transmission sprocket 6 is fixedly installed at the lower end of the main shaft 3. There are two sets of planetary transmission sprockets 6 and there is an obvious distance between them. This structure enables the equipment to drive the disk brush 5 to revolve, increasing the functionality of the equipment during use.

[0020] Further, the main transmission gear 7 is fixedly installed at the lower end of the transmission shaft 4. Two sets of idle gears 8 are meshed with the main transmission gear 7. Another set of idle gear 8 is meshed with the two sets of idle gears 8. Four sets of idle gears 8 are all meshed with the power output shaft gear 9. This structure enables the disk brush 5 to rotate self - rotatably driven by the transmission shaft 4. Cooperating with the fact that the disk brush 5 itself can revolve, it realizes a large area and relatively comprehensive work of the disk brush 5.

[0021] Further, the distances between the four sets of power output shaft gears 9 are equal, and the angles between the four sets of power output shaft gears 9 are all ninety degrees. This structure enables the installation of the disk brush 5 to be regular, optimizes the structure of the equipment, and increases the stability of the equipment during use.

[0022] Working principle: The planetary transmission sprocket 6 is driven to rotate by a chain. The planetary transmission sprocket 6 drives the main shaft 3 and the mounting disk 1 to rotate to form a revolution. The transmission shaft 4 transmits the power of the motor to the main transmission gear 7 inside the gearbox 2. The main transmission gear 7 drives the idle gear 8 to rotate. The idle gear 8 drives the power output shaft gear 9. The power output shaft gear 9 drives the disk brush 5 at its end to form a self - rotation. There are four sets of disk brushes 5 in total, two of which rotate forward, and the other two rotate in reverse by virtue of the different numbers of idle gears 8. The entire mounting disk 1 revolves, and the four sets of disk brushes 5 rotate forward and backward self - rotatably to polish the product, with a better effect. The above is all the working principles of this utility model.

[0023] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
