Description

Technical Field

[0001] The invention relates to the technical field of air filter paper origami, and in particular to an air filter paper origami device. Background Art

[0002] Air filter paper, also known as air filter paper, is a semi-permeable paper barrier placed perpendicular to a liquid or air flow. It is used to separate fine solid particles from gases. Made from softwood, hardwood, fiber crops, or mineral fibers, it is ultimately placed in the filter. Before being placed in the filter, it undergoes a folding process, often using a roller folding machine. The filter paper is first guided and conveyed, then rolled by scoring rollers, and finally reeled.

[0039] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0040] like Figures 1 to 9 As shown, this embodiment proposes an air filter paper folding device, including

[0041] Frame 1, with workbench 2,

[0042] The marking roller pair 3 is rotatably arranged on the frame 1, and the marking roller pair 3 has a marking gap 4.

[0043] A gluing member 5 is provided on the frame 1 , a gluing gap 6 is formed between the gluing member 5 and the workbench 2 , and a gluing bonding area 7 is formed between the workbench 2 , the scoring roller 3 and the gluing member 5 .

[0044] The limiting plate 8 is movably set on the workbench 2 and is located in the gluing and bonding area 7. The puncturing gap 4 and the gluing gap 6 are both used for passing filter paper, and the gluing member 5 and the puncturing roller 3 are arranged in sequence along the filter paper conveying direction.

[0045] Furthermore, the glue coating gap 6 is located below the puncture gap 4, and further includes

[0046] Three conveying rollers 9 are rotatably arranged on the frame 1 , and the filter paper is used to contact the three conveying rollers 9 in sequence and pass through the puncture gap 4 .

[0047] In this embodiment, in order to solve the problem that the filter paper produced by the folding machine has low strength, this scheme is designed to bond a new filter paper to the filter paper that has completed the folding operation by applying glue, and pressing the pressing rollers on the frame 1 by rotating them, thereby completing the operation of improving the strength; this scheme uses a rotating scoring roller 3 to make a filter paper that has been transported through three conveying rollers 9 in sequence pass through the scoring gap 4, and under the driving action of the rotating squeezing of the scoring roller 3, the folding operation of the filter paper is realized, and because the glue coating member 5 and the scoring roller 3 that apply glue to the filter paper transported from the other side are pressed together, the filter paper is folded. 3 are arranged in sequence along the conveying direction of the filter paper, so that the filter paper that has completed the folding operation gradually approaches and adheres to the other filter paper conveyed along the workbench 2 under the action of its own gravity and the action of the conveying roller 9, and completes the bonding operation in the gluing and bonding area 7. The gluing member 5 applies glue to the other filter paper in the gluing gap 6, and usually three layers of glue are applied, one for sealing and the other two for bonding, which greatly improves the bonding effect. At the same time, a limit plate 8 is movably provided on the workbench 2 to limit the filter paper when the pressing roller acts to prevent it from running off.

[0048] Furthermore, the rotation axis of the conveying roller 9 , the rotation axis of the puncturing roller 3 , and the moving direction of the limit plate 8 are parallel to each other, and the filter paper conveying direction is perpendicular to the rotation axis of the puncturing roller 3 .

[0049] In this embodiment, in order to ensure the overall stable operation, the rotation axis of the conveying roller 9, the rotation axis of the puncturing roller 3 and the moving direction of the limit plate 8 are set to be parallel to each other, and the filter paper conveying direction is perpendicular to the rotation axis of the puncturing roller 3.

[0050] Furthermore, it also includes

[0051] An arc-shaped guide plate 10 is provided on the frame 1 , located in the glue-coating and bonding area 7 and on one side of the puncture gap 4 . The arc-shaped guide plate 10 is used to receive the filter paper.

[0052] In this embodiment, an arc-shaped guide plate 10 is installed on one side of the puncture slit 4 to guide the filter paper after the folding operation, prevent wind or other influencing factors from affecting the filter paper, and ensure stable transportation.

[0053] Furthermore, it also includes two correcting components 11, both of which are arranged on the frame 1, one of which is located in the gluing and bonding area 7 and below the puncture roller 3, and the other is located on the side of the gluing part 5 away from the puncture roller 3. The correcting component 11 includes

[0054] The frame 22 is provided on the frame 1.

[0055] Two deflection correcting frames 12, both of which are arranged on the frame 22 via a first elastic member 23, wherein the first elastic member 23 provides a force for the deflection correcting frames 12 to move away from the frame 22.

[0056] The correction roller 13 is rotatably arranged on the correction frame 12. A correction gap 14 is formed between the two correction rollers 13. The correction gap 14 is used to pass the filter paper. The correction roller 13 has an adjustment cavity 15 and a plurality of arc-shaped correction openings 16. The plurality of arc-shaped correction openings 16 are connected to the adjustment cavity 15.

[0057] The arc-shaped correcting member 17 is arranged in the adjustment inner cavity 15 and moves radially along the correcting roller 13. After moving, the arc-shaped correcting member 17 extends into or out of the arc-shaped correcting opening 16. Several arc-shaped correcting members 17 are used to form a spiral correcting part.

[0058] In this embodiment, since this solution bonds two strands of filter paper together, in order to ensure that the two strands are bonded more accurately and without affecting the folding operation of one strand of filter paper, two correction components 11 are provided, one of which is located below the puncturing roller 3 to correct the folded filter paper, and the other is located on the side of the glue coating part 5 away from the puncturing roller 3 to correct the position before gluing, so that the filter paper produced in the glue coating and bonding area 7 will have good quality.

[0059] The essence of deviation correction is actually the transition from deviation to correct position. This solution adopts two deviation correction frames 12 symmetrically arranged on the frame 22, on which deviation correction rollers 13 are rotatably arranged, so that the filter paper passes through the deviation correction gap 14 formed between the two deviation correction rollers 13. The force provided by the first elastic member 23 makes the two deviation correction rollers 13 firmly abut against the filter paper and can also provide a certain conveying effect for it. When normal work does not require deviation correction, the arc-shaped deviation correction member 17 is controlled to extend into the arc-shaped deviation correction port 16 to ensure that the deviation correction rollers 13 are smooth rollers. The two groups of smooth rollers rotate and stably convey the filter paper in the correct position. Paper, and when correction is needed, the arc-shaped correction member 17 is controlled to extend out of the arc-shaped correction mouth 16, so that several arc-shaped correction members 17 can form a complete set of spiral correction parts, which then replace the correction roller 13 to abut against the filter paper. The first elastic member 23 receives a compression force, so that the two correction rollers 13 move away from each other, and the spiral correction part rotates to correct the position of the filter paper. The arc-shaped correction mouths 16 of the two sets of correction rollers 13 can be designed to be the same or opposite, corresponding to different usage conditions. When correcting the deviation, it is not necessary to extend both sets of arc-shaped correction members 17 out of the arc-shaped correction mouth 16. Extending one group can complete the correction operation.

[0060] Furthermore, the correction component 11 also includes

[0061] The adjusting member 18 is arranged on the correcting roller 13 so as to move along the axial direction of the correcting roller 13. One end of the adjusting member 18 is located in the adjusting inner cavity 15.

[0062] The abutment member 19 is provided at the bottom of the arc-shaped deviation-correcting member 17.

[0063] The second elastic member 20 has one end connected to the inner wall of the correcting roller 13 and the other end connected to the abutment member 19. The second elastic member 20 provides a force to move the abutment member 19 away from the inner wall of the correcting roller 13. The adjusting member 18 abuts or cancels the abutment member 19 after moving.

[0064] Furthermore, the abutment member 19 has a guiding inclined surface 21 .

[0065] In this embodiment, in order to facilitate the control of the arc-shaped correcting member 17 to extend out of the arc-shaped correcting mouth 16, the adjusting member 18 is moved to the adjusting cavity 15 set inside the correcting roller 13. After the movement, it will abut against the abutting member 19 at the bottom of the arc-shaped abutting member 19, and under the action of the guide slope 21, it slowly compresses the second elastic member 20 to achieve the purpose of extending the arc-shaped correcting member 17. To extend into the arc-shaped correcting mouth 16, it only needs to pull out the adjusting member 18, that is, to break away from the abutting state between the adjusting member 18 and the abutting member 19.

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
