Technical Field
[0001] This utility model relates to the field of roller brush manufacturing technology, and in particular to a device for correcting the roundness of roller brushes. Background Technology
[0002] A roller brush, also known as a roller, is a tool specifically designed for rolling paint over large areas. During the manufacturing process, the roller brush first needs to be bristled. The bristles on the roller brush after bristling are not uniform and need to be trimmed to ensure that the roller brush can maintain its round shape after long-term use and avoid deformation that affects the painting effect.
[0003] Existing roller brush roundness correction devices are not convenient for collecting the cut bristles when trimming the bristles on the roller brush. Because the cut bristles are small, they scatter on the bottom surface during the trimming process, making them difficult to clean and collect. Therefore, a roller brush roundness correction device is designed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to solve the problems existing in the background art mentioned above, and to propose a device for correcting the roundness of a roller brush.
[0005] The technical problem to be solved by this utility model is to provide a device for correcting the roundness of a roller brush, thereby solving the problem that existing roller brush roundness correction devices are not convenient for cleaning and collecting the cut brush bristles.
[0006] This utility model provides a device for correcting the roundness of a roller brush, including a funnel box, a first motor, and a roller brush mounting rod.

[0023] Example:
[0024] like Figures 1-4 As shown, an embodiment of this utility model provides a device for correcting the roundness of a roller brush, including a funnel box 1, a first motor 2, and a roller brush mounting rod 3. The first motor 2 is mounted on the left side of the upper surface of the funnel box 1 via a mounting block. The roller brush mounting rod 3 is fixedly installed at the output end of the first motor 2. A cutting component is fixedly installed on the outer side of the upper surface of the funnel box 1.
[0025] With the funnel box 1 in place, when the roundness of the roller brush is corrected, the roller brush is fixedly installed on the roller brush mounting rod 3. The first motor drives the roller brush mounting rod 3 and the roller brush to rotate. The cutting component cuts the bristles on the surface of the roller brush, thereby achieving the effect of roundness correction of the roller brush. The cut bristles fall down through the funnel box 1. The bristles can be easily collected by attaching a collection bag to the bottom of the funnel box 1.
[0026] In this embodiment, the cutting assembly includes a mounting plate 4, a guide rod 5, a rectangular frame 6, a lead screw 7, a first cutting blade 8, a second cutting blade 9, and a second motor 10. The guide rod 5 is provided through both the left and right sides of the mounting plate 4. The rectangular frame 6 is fixedly provided at the inner end of the guide rod 5. The lead screw 7 is threadedly connected to the center of the mounting plate 4, and the end of the lead screw 7 is rotatably provided at the bottom of the rectangular frame 6 through a bearing. The first cutting blade 8 is fixedly provided at the bottom inner side of the rectangular frame 6. The second cutting blade 9 is provided above the first cutting blade 8. The guide rod 901 is fixedly provided at both the left and right ends of the second cutting blade 9, and the guide rod 901 passes through the left and right side surfaces of the rectangular frame 6. The second motor 10 is fixedly provided at the center of the upper surface of the rectangular frame 6. An eccentric wheel 1001 is fixedly provided at the output end of the second motor 10. Two impact bars 902 are provided at the center of the upper surface of the second cutting blade 9.
[0027] In this embodiment, the horizontal height of the upper surface of the first cutting blade 8 is equal to the horizontal height of the axis of the roller brush mounting rod 3, which makes it convenient to determine the trimming length of the bristles on the roller brush by adjusting the distance between the first cutting blade 8 and the second cutting blade 9 and the roller brush mounting rod 3.
[0028] In this embodiment, the inner ends of both the first cutting blade 8 and the second cutting blade 9 are serrated, and the bottom surface of the second cutting blade 9 is attached to the upper surface of the first cutting blade 8, which facilitates the first cutting blade 8 to work with the second cutting blade 9 to trim the bristles on the roller brush.
[0029] In this embodiment, the eccentric wheel 1001 extends between the two impact bars 902, and the distance between the two impact bars 902 is equal to the length of the eccentric wheel 1001. When the eccentric wheel 1001 rotates, it will impact the two impact bars 902, which makes it convenient for the eccentric wheel 1001 to drive the second cutting blade 9 to move left and right, so that the second cutting blade 9 can work with the first cutting blade 8 to trim the bristles on the roller brush.
[0030] After the roller brush with the required roundness is fixedly installed on the roller brush mounting rod 3 by setting the cutting component, the lead screw 7 is rotated according to the required bristle length on the roller brush. The lead screw 7 drives the rectangular frame 6 to move in and out. The rectangular frame 6 drives the distance between the first cutting blade 8 and the roller brush mounting rod 3. After the first cutting blade 8 and the second cutting blade 9 reach the predetermined position, the first motor 2 and the second motor 10 are turned on. The first motor 2 drives the roller brush mounting rod 3 and the roller brush to rotate, and the second motor 10 drives the eccentric wheel 1001 to rotate. The eccentric wheel 1001 hits the two impact bars 902, causing the second cutting blade 9 to move left and right. When the bristles are at the serrations at the inner ends of the first cutting blade 8 and the second cutting blade 9, the left and right movement of the second cutting blade 9, in conjunction with the first cutting blade 8, can cut the bristles, resulting in a good cutting effect.
[0031] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
