[0002] An air filter is an accessory that uses filter paper to filter impurities or gases; it is commonly used in automobile engines. Since the filtration efficiency of an air filter can be improved by replacing the filter paper after a certain period of use, it is usually necessary to bend one side of the filter paper to make it easier for maintenance personnel to remove the filter paper to be replaced.
[0003] Currently, after filter paper is cut, it is usually folded manually to create a crease on one side. However, this production method is not only time-consuming and labor-intensive, but also limits the efficiency of filter paper production. Setting up a separate device for filter paper folding would increase production costs, thus increasing the burden on enterprises.
[0004] Therefore, a new device is urgently needed. Utility Model Content

The feeding component 1 is connected to the frame 2 and is used to hold the roll of filter paper. The filter paper is pulled out from the feeding component 1 under traction. The base 3 is detachably fixed to the frame 2, and the feeding component 1 is in front of the base 3 when viewed along the direction of filter paper movement. The guide component is located on the base 3 and is used to guide the movement of the filter paper; that is, during the movement of the filter paper, the guide component provides stability assistance. The fixed shaft 4 is located on the base 3, the crease seat 5 is detachably fixed to the fixed shaft 4, and the crease knife 6 is located on the crease seat 5. The crease knife 6 has a blade head that cuts across the conveying filter paper, leaving a mark on the filter paper without tearing it. This leaves a crease on the filter paper when it enters the filter, which facilitates the replacement of the filter paper in the filter. The filter paper feeding mechanism with crease function provided by this utility model can replace the manual intervention in the filter paper crease process, and also replace the need to set up additional crease equipment, which not only saves production costs, but also effectively improves production efficiency.
[0043] Furthermore, such as Figures 1-6 As shown in the figure, this embodiment proposes that the crease seat 5 is provided with a mounting hole and a connecting hole. The mounting hole is connected to the connecting hole, the fixed shaft 4 is inserted into the connecting hole, and a first bolt 7 is threaded into the mounting hole. The end of the first bolt 7 abuts against the outer edge of the fixed shaft 4.
[0044] In this embodiment, to facilitate the installation and removal of the crease holder 5 and to adjust the angle of the crease cutter 6 (the angle between the blade and the horizontal plane), a connecting hole is made on the crease holder 5, and the fixing shaft 4 passes through the connecting hole. Then, a mounting hole is made on the end face of the crease holder 5, which connects to the connecting hole. The mounting hole is a threaded hole, while the connecting hole is a smooth hole. A first bolt 7 is provided in the mounting hole, and the end of the first bolt 7 abuts against the fixing shaft 4, thereby fixing the crease holder 5 to the fixing shaft 4. In addition, when the first bolt 7 is loosened, the crease holder 5 can be rotated, thereby adjusting the angle of the crease cutter 6.
[0045] Furthermore, such as Figures 1-6 As shown in the figure, this embodiment proposes that the crease seat 5 is also provided with a receiving groove, the crease knife 6 is connected in the receiving groove and the knife head protrudes outside the receiving groove.
[0046] In this embodiment, to prevent the crease cutter 6 from scratching personnel during replacement or maintenance, a receiving groove is provided on the crease seat 5, and the crease cutter 6 is placed in the receiving groove. It can be fixed by snap-fitting, embedding, or adhesive bonding.
[0047] Furthermore, such as Figures 1-6 As shown in the figure, this embodiment proposes that the crease seat 5 has a first adjustment hole and a locking hole on its side. The first adjustment hole passes through the receiving groove and both sides of the crease seat 5, and the locking hole is connected to the receiving groove. The crease knife 6 has a second adjustment hole, which passes through the crease knife 6. An adjustment shaft 9 is connected to both the first adjustment hole and the second adjustment hole. A second bolt 8 is threaded into the locking hole.
[0048] In this embodiment, to further improve the ease of disassembly and installation of the crease cutter 6, a first adjustment hole and a locking hole are provided on the side of the crease seat 5. The first adjustment hole passes through the crease seat 5 and the receiving groove, while the locking hole only connects to the receiving groove. The first adjustment hole is a smooth hole, and the locking hole is a threaded hole. A second adjustment hole is provided on the crease cutter 6. An adjustment shaft 9 is inserted into the first and second adjustment holes, and the axis of the adjustment shaft 9 is parallel to the axis of the fixed shaft 4. A second bolt 8 is inserted into the locking hole, allowing the crease cutter 6 to be detachably connected to the receiving groove. In addition, the cutter head angle can be finely adjusted through the cooperation of the first adjustment hole, the second adjustment hole, and the adjustment shaft 9.
[0049] Furthermore, such as Figures 1-6 As shown, in this embodiment, the base 3 is concave, and the guide assembly, fixing shaft 4, crease seat 5 and crease knife 6 are all located in the concave part of the base 3.
[0050] In this embodiment, in order to avoid interference from external structures and to prevent the crease knife 6 from scratching other components, the base 3 is concave, and the guide assembly, fixing shaft 4, crease seat 5 and crease knife 6 are all located in the recess of the base 3.
[0051] Furthermore, such as Figures 1-6 As shown, this embodiment proposes a guiding component including:
[0052] The first guide roller 10 is set in the recess of the base 3;
[0053] The second guide roller 11 is set in the recess of the base 3;
[0054] The third guide roller 12 is set in the recess of the base 3;
[0055] The axes of the first guide roller 10, the second guide roller 11, and the third guide roller 12 are all parallel and perpendicular to the direction of movement of the filter paper.
[0056] The plane formed by the axes of the second guide roller 11 and the third guide roller 12 is parallel to the horizontal plane.
[0057] The projection of the crease cutter 6's blade tip onto the base 3 lies between the projections of the second guide roller 11 and the third guide roller 12.
[0058] In this embodiment, to ensure high stability of the filter paper during crease formation, the guiding assembly includes a first guide roller 10, a second guide roller 11, and a third guide roller 12, all disposed in the recess of the base 3. The filter paper passes over the first guide roller 10 and then under the second guide roller 11 and the third guide roller 12. At this time, the second guide roller 11 and the third guide roller 12 provide some guidance to the portion of the filter paper to be creased, and this portion of the filter paper is placed horizontally. The creasing blade, in conjunction with the base 3, cuts the filter paper, leaving scratches. Since the projection of the creasing blade on the base 3 is located between the projections of the second guide roller 11 and the third guide roller 12, the stability during the creasing process is greatly improved.
[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
