Technical Field

[0001] The utility model relates to the technical field of flattening rollers, and particularly relates to a brush flattening roller. Background Art

[0002] During the processing of films and papers, due to easy wrinkling, the rejection rate is relatively high. Therefore, it is usually necessary to be guided by a flattening roller. The flattening rollers mainly include left and right thread flattening rollers, bow-shaped flattening rollers, edge flattening rollers, and drum-shaped flattening rollers.

[0003] The flattening effect of the current flattening rollers is not good, and it cannot better eliminate wrinkles, so the effect of reducing the rejection rate is not obvious. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a brush flattening roller.

[0005] An embodiment of the utility model provides a brush flattening roller, including: a flattening roller body and a brush assembly arranged on the flattening roller body;

[0006] The brush assembly includes a plurality of first brushes and a plurality of second brushes. The plurality of first brushes and the plurality of second brushes are evenly arranged on the outer side of the flattening roller body. The plurality of first brushes gradually incline and extend towards the left end of the flattening roller body in the direction from the root to the end of the first brush, and the plurality of second brushes gradually incline and extend towards the right end of the flattening roller body in the direction from the root to the end of the second brush.

[0007] In some alternative embodiments, the flattening roller body is divided into a left half section and a right half section. The plurality of first brushes are arranged on the left half section, and the plurality of second brushes are arranged on the right half section.

[0008] In some alternative embodiments, the first brush has a first inclination angle relative to the axis of the flattening roller body, and the first inclination angle gradually decreases in the direction close to the left end of the flattening roller body.

[0009] In some alternative embodiments, the second brush has a second inclination angle relative to the axis of the flattening roller body, and the second inclination angle gradually decreases in the direction close to the right end of the flattening roller body.

[0010] In some alternative embodiments, rotating mounting structures are respectively arranged at the left and right ends of both ends of the flattening roller body.

[0011] In some alternative embodiments, the rotational mounting structure includes a rotating shaft and a bearing. The bearing is disposed at the end of the flattening roller body, and the rotating shaft passes through the bearing. The rotational mounting structure can adopt a non-powered rotation design with low rotational resistance, enabling it to rotate easily and smoothly. It is conducive to driving the rotation of the flattening roller body by the force of guiding the film or paper.

[0012] In some alternative embodiments, the flattening roller body includes an outer sleeve, a lining, and two connecting flanges. The outer sleeve is sleeved outside the lining. A plurality of the first brushes and a plurality of the second brushes are evenly arranged outside the outer sleeve. The bearing is correspondingly disposed at the end of the lining and is located inside the outer sleeve. The connecting flanges are respectively disposed at both ends of the outer sleeve and limit the bearing inside the outer sleeve.

[0013] In some alternative embodiments, the bearing is a ball bearing.

[0014] In some alternative embodiments, the rotating shaft includes a rotating portion and a mounting portion connected to each other. The rotating portion is connected to the bearing. A limiting step is formed between the rotating portion and the mounting portion, and the limiting step abuts against the end of the flattening roller body.

[0015] Compared with the prior art, the brush flattening roller of the present utility model presses the film or paper with soft brushes, and the brushes are at a certain inclination angle. When the brushes press on the film or paper, the elastic force after the brushes bend can horizontally push the wrinkles of the film or paper, thereby achieving the effect of eliminating wrinkles. Moreover, the first brush and the second brush cooperate to brush from the center of the film or paper to the left and right sides, which can effectively flatten the overall film or paper, thus extremely effectively reducing the rejection rate.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Please refer to Figure 1 As shown in the figure, an embodiment of the present invention provides a brush flattening roller, including: a flattening roller body 10 and a brush assembly 20 provided on the flattening roller body 10.

[0024] Please refer to Figure 2 As shown in the figure, the brush assembly 20 includes a plurality of first brushes 21 and a plurality of second brushes 22. The plurality of first brushes 21 and the plurality of second brushes 22 are evenly arranged on the outer side of the flattening roller body 10. The plurality of first brushes 21 gradually incline and extend towards the left end of the flattening roller body 10 in the direction from the root to the end of the first brush 21, and the plurality of second brushes 22 gradually incline and extend towards the right end of the flattening roller body 10 in the direction from the root to the end of the second brush 22. By pressing the soft fiber tufts of the first brush 21 and the second brush 22 against the film or paper, the elastic force after the fiber tufts are bent when pressing on the film or paper can press the film or paper tightly, avoiding wrinkles on the film or paper. Moreover, the first brush 21 and the second brush 22 adopt a certain inclination angle, and the inclined fiber tufts can push the wrinkles horizontally, thereby achieving the effect of eliminating wrinkles.

[0025] In some alternative embodiments, the flattening roller body 10 is divided into a left half section and a right half section. A plurality of first brushes 21 are arranged on the left half section, and a plurality of second brushes 22 are arranged on the right half section. The first brush 21 and the second brush 22 cooperate to brush the film or paper from the center to both sides, and can effectively flatten the overall film or paper from the middle to both sides. When the flattening roller body 10 rotates, the first brush 21 and the second brush 22 continuously brush the overall film or paper, which can well eliminate wrinkles, thereby extremely effectively reducing the rejection rate.

[0026] In some alternative embodiments, the first brush 21 has a first inclination angle relative to the axis of the flattening roller body 10, and the first inclination angle gradually decreases in the direction approaching the left end of the flattening roller body 10, which is conducive to the first brush 21 continuously brushing the wrinkles in the middle of the film or paper towards the left side of the film or paper. Of course, the first brush 21 near the middle position of the flattening roller body 10 can also adopt the design with the gradually decreasing first inclination angle as described above, while the first inclination angle of the first brush 21 near the left end of the flattening roller body 10 remains unchanged, so as to prevent the first brush 21 near the end from not contacting the film or paper.

[0027] In some alternative embodiments, the second brush 22 has a second inclination angle relative to the axis of the flattening roller body 10, and the second inclination angle gradually decreases in the direction approaching the right end of the flattening roller body 10, which is conducive to the second brush 22 continuously brushing the wrinkles in the middle of the film or paper towards the right side of the film or paper. Of course, the second brush 22 near the middle position of the flattening roller body 10 can also adopt the design with the gradually decreasing second inclination angle as described above, while the second inclination angle of the second brush 22 near the right end of the flattening roller body 10 remains unchanged, so as to prevent the second brush 22 near the end from not contacting the film or paper.

[0028] In some alternative embodiments, rotating mounting structures 11 are respectively arranged at the left and right ends of both ends of the flattening roller body 10, facilitating the rotating mounting of the flattening roller body 10 at a suitable position.

[0029] Please refer to Figure 3 , in some alternative embodiments, the rotating mounting structure 11 includes a rotating shaft 12 and a bearing 13. The bearing 13 is arranged at the end of the flattening roller body 10, and the rotating shaft 12 passes through the bearing 13. The bearing 13 effectively reduces the friction force. When the flattening roller body 10 rotates freely without power, when the film or paper drives the flattening roller body 10 to rotate as it passes through the flattening roller body 10, it can effectively drive the flattening roller body 10 to rotate and reduce the risk of jamming.

[0030] In some alternative embodiments, the bearing 13 is a ball bearing 13. The ball bearing 13 is conducive to further reducing the friction and improving the smoothness and stability of the flattening roller body 10 during rotation. Of course, according to actual design requirements, the bearing 13 can also adopt other suitable bearings 13, and is not limited to ball bearings 13.

[0031] To facilitate the installation of the bearing 13, in some alternative embodiments, the flattening roller body 10 includes an outer sleeve 14, an inner lining 15, and two connecting flanges 16. The outer sleeve 14 is sleeved on the outside of the inner lining 15. A plurality of first brushes 21 and a plurality of second brushes 22 are arranged evenly on the outside of the outer sleeve 14. The bearing 13 is correspondingly arranged at the end of the inner lining 15 and is located inside the outer sleeve 14. The connecting flanges 16 are respectively arranged at both ends of the outer sleeve 14 and limit the bearing 13 inside the outer sleeve 14. The connecting flange 16 can be directly threadedly engaged with the inner lining 15 through threaded members. The connecting flange 16 can also be connected to the bearing 13 through threaded members, and the threaded members can pass through the bearing 13 and be threadedly engaged with the inner lining 15. Of course, the bearing 13 can also adopt other suitable installation methods, which is not limited to this example.

[0032] Please refer to Figure 4 , in some alternative embodiments, the rotating shaft 12 includes a rotating part 121 and a mounting part 122 that are connected to each other. A limiting step is formed between the rotating part 121 and the mounting part 122. The rotating part 121 is connected to the bearing 13. The limiting step can limit the position of the rotating shaft 12 by abutting against the end of the bearing 13, improving the stability of the rotating shaft 12. This design also facilitates the mutual fixation of the mounting part 122 and other fixed positions.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
