Description

Technical Field

[0001] This utility model relates to the field of roller brush grinding equipment, and in particular to a grinding equipment for roller brush processing and production. Background Technology

[0002] Roller brushes are cleaning tools or equipment widely used in industrial and home environments. They work by rotating the brush bristles via a brush shaft, using the friction between the bristles and the surface of the object to effectively remove dust, stains, rust, and other impurities, thus achieving the cleaning purpose. They are suitable for various cleaning needs such as mechanical parts, floors, and equipment surfaces, and are an important tool for improving cleaning efficiency and quality.

[0003] In the manufacturing process, the connection and fixation of bristles to the brush shaft typically employs two main methods: winding or embedding. However, regardless of the chosen fixing process, strict requirements are placed on the surface treatment of the brush shaft. The brush shaft surface must be highly flat, without any unevenness; simultaneously, it must be free of stains and other impurities. This is because the condition of the brush shaft surface directly affects the fixing effect of the bristles. If the brush shaft surface is uneven or contains impurities, the bristles may not be firmly fixed to the brush shaft, thus affecting the overall performance and service life of the roller brush. Therefore, grinding the brush shaft is an essential step in the roller brush production process. Grinding effectively removes any impurities that may be adhering to the brush shaft surface, providing an ideal surface condition for subsequent bristle fixing and ensuring the production quality of the roller brush.

[0004] While existing brush shaft grinding equipment can perform grinding, it also has certain problems. First, it is difficult to adapt to different specifications of roller brushes, limiting its applicability; second, it lacks a dust prevention and removal structure, resulting in dust flying everywhere, threatening personnel health and polluting the environment; and third, the installation of the brush shaft to be ground is inconvenient, affecting grinding efficiency. Therefore, it is necessary to improve and optimize the existing equipment. Utility Model Content

The second three-jaw chuck 19 is opposite to the first three-jaw chuck 12 and their center points are aligned.

[0025] The difference between the first fixing device 4 and the second fixing device 5 is that the fixing base plate 9 in the first fixing device 4 is fixed to the table body 1, the front wall of the fixing base plate 9 in the second fixing device 5 is fixed to the drive plate 20, and the lower sides of the fixing base plate 9 in the second fixing device 5 are fixed to the pulley frame 21, the pulley frame 21 is rotatably connected to the pulley 22, and the upper sides of the table body 1 are provided with pulley grooves 23 that are adapted to the pulley 22.

[0026] The driving device 3 is used to drive the first fixed device 4 to move back and forth. It includes a guide plate 24, a driving rod 25, a driving gear 26, and a third electric push rod 27. The front end of the driving rod 25 is fixed to the driving plate 20, and the rear end moves through the guide plate 24 fixed above the table body 1.

There are two first electric push rods 8, located on both sides of the table body 1, and their telescopic ends are fixedly connected to the lower end of the first support plate 33 respectively. There are two guide rods 7, located on both sides of the table body 1, and their upper ends move through the second support plate 34 respectively.

[0029] The dust cover is made of transparent plastic.

[0030] A dust suction port 35 is provided above the table body 1, between the first fixing device 4 and the second fixing device 5. The lower end of the dust suction port 35 is connected to the vacuum cleaner 36 through a pipe. The vacuum cleaner 36 is located in the box 37 below the table body 1. The front end of the box 37 is connected to the box door 38.

[0031] The principle of this utility model is as follows: In the production process of roller brushes, this utility model provides a grinding device for roller brush production to meet the grinding requirements of roller brushes of different specifications. First, the first fixing device 4 is used to clamp the brush shaft 40 to be polished, and the second fixing device 5 is used to clamp the polishing roller brush 39. The movable slide plate 13 and the second three-jaw chuck 19 in the first fixing device 4 and the second fixing device 5, combined with the drive device 3, drive the second fixing device 5 to move back and forth. Specifically, the third electric push rod 27 pushes the gear frame 30, causing the drive gear 26 to rotate. Since the drive gear 26 meshes with the first rack 28 and the second rack 29, it drives the drive rod 25 to move back and forth, thereby causing the second fixing device 5 to slide in the pulley groove 23 via the pulley 22. This allows for flexible adjustment of the distance between the two fixing devices, so that the polishing roller brush 39 can contact the brush shaft 40 to be polished, thus achieving the polishing work. This solves the problem that existing grinding equipment is difficult to adapt to different specifications of roller brushes and has a limited range of applications. In actual polishing, the drive motor 42 in the first fixing device 4 drives the brush shaft 40 to be polished in the opposite direction to the rotation of the polishing roller brush 39 driven by the drive motor 42 in the second fixing device 5, thus achieving the polishing work. During the grinding process, the dust removal device 2 plays an important role. The dust cover 6 is located above the first fixing device 4 and the second fixing device 5, effectively preventing dust from flying around. Simultaneously, a suction port 35 is provided above the table body 1, between the first fixing device 4 and the second fixing device 5. The lower end of the suction port 35 is connected to a vacuum cleaner 36 via a pipe. The vacuum cleaner 36 is located inside a box 37 under the table body 1. During polishing, the vacuum cleaner 36 can promptly remove dust through the suction port 35, reducing the threat of dust to personnel health and environmental pollution, overcoming the shortcomings of existing equipment lacking a dust-proof and dust-removing structure. Furthermore, the dust cover 6 is a transparent plastic structure, so it does not affect the worker's real-time monitoring of the polishing progress. In addition, both the first fixing device 4 and the second fixing device 5 use a three-jaw chuck to fix the brush shaft, making operation simple and quick. When loading and unloading are required, the second electric push rod 16 pushes the slide plate 13, causing the second three-jaw chuck 19 to move, facilitating the installation and removal of the brush shaft and polishing roller brush 39, improving grinding efficiency, and addressing the problem of inconvenient installation of the brush shaft to be ground in existing equipment. Through the above design, this utility model achieves effective grinding of roller brushes of different specifications, while ensuring a clean grinding environment and convenient operation.

[0032] In addition, since this utility model is a polishing device, dust or impurities will be scattered in the pulley groove 23 and slide groove 15 during the polishing process. Therefore, in actual use, it is necessary to regularly use a vacuum cleaner to clean the entire device in order to maintain the normal use of the entire device.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
