Abstract
Description
Technical Field
[0001] The utility model relates to a needle roller, in particular to a needle roller with a protective function. Background Art
[0002] When it comes to the use of needle rollers, there are indeed some safety hazards and practical difficulties that cannot be ignored. First of all, the design of the needle roller makes it inevitable that the needle tip is exposed when in use, which undoubtedly increases the danger during operation. Imagine that those sharp needle tips are like small swords. Once improper operation or negligence, accidents may occur, such as scratching the skin, piercing clothes, etc., and in severe cases, it may even cause more serious harm to the human body.
[0003] Secondly, the needles of the needle roller are usually arranged very densely. Although this design improves its working efficiency to a certain extent, it also brings a tricky problem, that is, it is difficult to clean up the debris. Since the gap between the needles is extremely small, it is difficult to completely remove the debris once it enters. These debris may be fine fibers, dust, or other particles that are not easy to detect. They will not only affect the normal operation of the needle roller, but also have an adverse effect on the product quality. What's worse, if the debris accumulates too much, it may also damage the needle roller itself and shorten its service life. Utility Model Content

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0023] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.
[0024] This embodiment mainly describes the structure of the needle roller, which is as follows: a needle roller with a protective function, such as Figure 1-Figure 4 As shown, it includes a needle roller 1, a mounting frame 2, a protective cover 4, a fixing screw 5 and a brush 7. The mounting frame 2 and the protective cover 4 form a hollow cylindrical structure. A handle 14 is fixedly connected to the side of the mounting frame 2 to facilitate the staff to move the device. The mounting frame 2 and the protective cover 4 are fixed at the connection using a fixing screw 5. A through groove is provided at the bottom of the protective cover 4 to provide a working space for the needle roller. The needle roller 1 is rotatably connected between the mounting frames 2. A bearing 3 is provided at the connection between the needle roller 1 and the mounting frame 2. A symmetrical fixing plate 6 is provided in the protective cover 4. The brush 7 is connected to the fixing plate 6 by a clamping method, and the brush 7 can frictionally contact the needle roller 1.
[0025] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a clamping block 8 and a rotating rod 9. The clamping block 8 is fixedly connected to the end of the fixed plate 6. The rotating rod 9 is slidably connected to the brush 7. A torsion spring 10 is provided at the connection between the rotating rod 9 and the brush 7. The torsion spring 10 provides elastic force for the rotating rod 9 to rotate and reset. A clamping rod is vertically provided at the end of the rotating rod 9, and the clamping rod can be embedded in the clamping block 8 to fix the brush 7.
[0026] like Figure 4 As shown, an anti-skid pad 12 is disposed at the end of the rotating rod 9 to facilitate the staff to rotate the rotating rod 9.
[0027] like Figure 4 As shown, a transparent observation window 11 is provided on the protective cover 4 to facilitate the staff to immediately observe the internal situation of the protective cover 4. An illuminating lamp 13 is provided on the inner side of the protective cover 4, and the illuminating lamp 13 points to the needle roller 1.
[0028] Working principle: the needle roller 1 is rotatably connected in the mounting frame 2, the upper part of the protective cover 4 is closed but has an observation window 11, and a through groove is provided at the bottom of the protective cover 4 for piercing. During the rotation of the needle roller 1, the brush 7 continuously brushes the surface of the needle roller 1 to remove the debris between the needles of the needle roller 1. As an optimization, a gap is provided in the brush 7 for the passage of the needles of the needle roller 1. By rotating the rotating rod 9, the clamping rod at its end can be detached from the clamping block 8, and then the staff can take the brush 7 out of the fixed plate 6 to clean or replace the brush 7.
