Description

Technical Field

[0001] The invention relates to the technical field of filter paper forming, and in particular to a filter paper forming device for a bypass machine. Background Art

[0002] Bypass filters are generally used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the engine oil to protect the engine.

[0003] The filter is equipped with filter paper. There is a kind of stacked filter paper on the market. The cross section of the filter paper is set to match the inner diameter of the two end covers and then stacked in sequence on the center tube to form a stacked filter element. Each piece of filter paper in this filter element has a filter hole. After stacking, it ensures that the fuel can flow through normally, but impurities will be retained between adjacent filter papers.

[0004] However, in the prior art, the production method for the above-mentioned filter paper is to first punch out the outer shape of the entire stack of filter paper through a stamping device, then punch out the filter holes and then punch out the center hole, or punch out the center hole while punching the filter holes or punch out the filter holes while punching the center hole. This step-by-step forming method is not only complicated and requires a large investment in equipment, but also has low processing efficiency, and the filter paper cannot be divided into several parts to produce different sizes.

[0041] 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.

[0042] like Figures 1 to 5 As shown, this embodiment provides a bypass filter paper forming device, comprising:

[0043] Frame 1, set on the ground;

[0044] A forming roller 2 is rotatably mounted on the frame 1, wherein both ends of the forming roller 2 each have a closed first embossing along its circumference, and a plurality of center hole embossings, a plurality of filter hole embossings, and a plurality of crease embossings are circumferentially arranged between the two first embossings;

[0045] a first pressing roller 3, rotatably mounted on the frame 1 and positioned above the forming roller 2, with a gap between the first pressing roller 3 and the forming roller 2;

[0046] A first conveyor belt 4 is provided on the frame 1 for circular conveying, and the forming roller 2 is located at the input end of the first conveyor belt 4;

[0047] The negative pressure adsorber 5 is provided on the frame 1 and located above the first conveyor belt 4, and is used for sucking away the filter paper embossed with the center hole and the filter hole.

[0048] In this embodiment, in order to solve the problem of low efficiency in filter paper processing and molding in related technologies, a molding roller 2 is used to press and mold the filter paper. The shapes of the first embossing, center hole embossing, filter hole embossing and crease embossing on the molding roller 2 can be independently designed according to actual needs, and then combined with a negative pressure adsorber 5, it can not only meet the needs of cutting the center hole and filter hole, but also meet the needs of folding along the crease, and the molding efficiency is more efficient.

[0049] The specific working principle is that the whole filter paper can be sent to the first pressing roller 3 and the forming roller 2 by a conveyor belt. The filter paper passes through the gap between the two rollers and is pressed and cut, and then continues to be conveyed forward by the first conveyor belt 4. When the filter paper is carried through the negative pressure adsorber 5, the excess filter paper pressed out can be adsorbed away. The filter paper raw material can be arranged with a pressing roller to limit it to prevent it from being sucked away. In this way, the filter paper can be formed.

[0050] Furthermore,

[0051] A traction limiting roller is rotatably arranged on the frame 1 and is located above the first conveyor belt 4. The traction limiting roller has a negative pressure hole;

[0052] A second conveyor belt 7 is obliquely arranged on the frame 1 and located above the first conveyor belt 4;

[0053] a first guide plate 8, obliquely arranged on the frame 1, with one end located above the first conveyor belt 4 and below the traction limiting roller, and the other end located at the input end of the second conveyor belt 7;

[0054] Two second guide plates 9 are both provided on the frame 1 and are respectively located on both sides of the first guide plate 8. The second guide plate 9 has a blocking portion 10. The blocking portion 10 is located below the traction limiting roller and has a gap with the first conveyor belt 4.

[0055] The forming roller 2 also has closed cutting embossing.

[0056] In this embodiment, in order to produce filter paper with a limited wide band, the entire filter paper needs to be divided into several strips. Therefore, cutting embossing is also designed on the forming roller 2 to press out dividing lines on the filter paper to facilitate the division of the filter paper.

[0057] After the filter paper passes through the negative pressure adsorber 5, it will pass through the traction limiting roller under the conveying action of the first conveyor belt 4. On the one hand, the traction limiting roller can absorb the head end of the filter paper upward through the negative pressure hole, so that it is slightly tilted upward. On the other hand, it can also limit the filter paper to prevent it from tilting upward too much. After the head end of the filter paper is tilted, the middle part will be placed on the first guide plate 8, and the other two parts will continue to fall on the first conveyor belt 4 and follow the transportation due to the obstruction of the blocking parts 10 of the two second guide plates 9. That is, there is a cutting line left by the cutting embossing between the middle part and the other two parts. Since the directions of the middle part and the other two parts are different, the filter paper can be cut along the cutting line by the first guide plate 8 and the second guide plate 9, and then divided into multiple strips according to the preset width.

[0058] In addition, one end of the first guide plate 8 is close to the upper surface of the first conveyor belt 4, which is conducive to the middle part of the filter paper entering the first guide plate 8, and the other end is close to the input end of the second conveyor belt 7, which is conducive to the smooth transition of the filter paper to the second conveyor belt 7.

[0059] Furthermore, the inclination angle of the first guide plate 8 is consistent with the inclination angle of the second conveyor belt 7 .

[0060] In this embodiment, the above design can make the filter paper transition smoothly to the second conveyor belt 7, avoiding accidental deviation.

[0061] Furthermore,

[0062] The connecting column 11 , the first guide plate 8 is split and consists of two guide parts 12 , the connecting column 11 is arranged on one of the guide parts 12 , and the other guide part 12 has a blind hole 13 , and the connecting column 11 is slidably arranged in the blind hole 13 .

[0063] In this embodiment, in order to adapt to different preset widths of filter paper, the first guide plate 8 is designed to be retractable, that is, the first guide plate 8 is split, and the two guide parts 12 can be moved closer or farther away to adjust the overall width of the first guide plate 8.

[0064] Furthermore, the inner wall of the blind hole 13 has a continuous arc-shaped concave surface 14 , and the connecting column 11 has a continuous arc-shaped protrusion 15 . The connecting column 11 is located in the blind hole 13 , and the protrusion 15 is stuck on the concave surface 14 .

[0065] In this embodiment, the spacing between the two guide portions 12 is adjusted in such a way that the protrusion 15 on the connecting column 11 is stuck in the concave surface 14 of the blind hole 13. The protrusion 15 and the concave surface 14 are continuous, and the two are not stuck. The protrusion 15 can be designed to have a certain elastic deformation. When a certain force is applied, the connecting column 11 can be pulled to adjust the spacing, or the connecting column 11 can be directly rotated to disengage the protrusion 15 from the concave surface 14, and then the spacing can be freely adjusted. After completion, the connecting column 11 is rotated in the opposite direction to stick the protrusion 15 into the concave surface 14 again.

[0066] Furthermore,

[0067] A first storage tank 16 is provided on the frame 1 and is located at the output end of the first conveyor belt 4;

[0068] A second storage slot 17 is provided on the frame 1 and is located on one side of the first storage slot 16;

[0069] The third storage slot 18 is provided on the frame 1 , above the first storage slot 16 and the second storage slot 17 , and at the output end of the second conveyor belt 7 .

[0070] In this embodiment, a first storage tank 16, a second storage tank 17 and a third storage tank 18 are subsequently installed to store the separated filter papers.

[0071] Furthermore,

[0072] The lifting block 19 is lifted and arranged on the frame 1 , and the first pressing roller 3 is arranged on the frame 1 through the lifting block 19 .

[0073] In this embodiment, a lifting block 19 is further designed to make the height of the first pressing roller 3 adjustable, thereby adjusting the paper feeding gap between the first pressing roller 3 and the forming roller 2 .

[0074] Furthermore,

[0075] The traction roller 20 is rotatably disposed on the frame 1 and is located at the output end of the second conveyor belt 7 .

[0076] In this embodiment, a traction roller 20 is further arranged at the output end of the second conveyor belt 7 to traction and guide the filter paper to prevent it from deviating.

[0077] 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.
