Description

Technical Field

[0001] The invention relates to the technical field of double-layer filter paper processing, and more specifically to a double-layer filter paper composite winding machine for processing and manufacturing vehicle filters. Background Art

[0002] At present, the filter paper (filter element) material of the oil (or fuel) filter used in the vehicle engine lubrication system is a composite paper that is folded in half. One side (half) of the large paper is flat paper, and the other side (the other half) is pleated paper. When the two are folded in half and then rolled up, wrinkles are likely to occur, and a certain gap is likely to appear in the middle, which may cause "filter short circuit" (i.e. poor filtering effect) and affect the filtering quality of the filter.

[0003] As shown in the patent document with publication number CN205651756U, the double-layer overlapping composite filter paper material produced in the device appears very flat, with no wrinkles on the surface and no gaps in the middle, which effectively avoids the "filter short circuit" phenomenon and significantly improves the filter quality and service life of the filter;

[0004] However, in a humid environment, the filter paper will become damp, resulting in the inability to better composite and connect the double-layer filter paper, and the paper scraps and impurities on the double-layer filter paper will also affect the composite of the two. The above-mentioned patent document cannot preheat the double-layer filter paper to remove moisture and dust before composite. In the composite of the double-layer filter paper, it is impossible to ensure the firmness of the composite by first wetting and pressing and then gluing. Therefore, the production quality of the double-layer filter paper is improved from two perspectives before and during the composite of the double-layer filter paper. Summary of the invention

The output end of the glue spraying head is arranged toward the lower layer of filter paper, and the glue spraying heads are connected by connecting hoses.

[0016] The method for manufacturing a vehicle filter by a double-layer filter paper composite winding machine includes the following two stages:

[0017] Pretreatment stage: hot air is delivered to the U-shaped tube, and the upper filter paper and the side wall to be laminated with the lower filter paper are blown and dehumidified through the two output ends of the U-shaped tube; part of the air is delivered to the limit tube, and the air bag is controlled to be continuously and intermittently filled to complete the gentle vibration of the double-layer filter paper, and the double-layer filter paper is thoroughly cleaned in coordination with the wind speed;

[0018] Composite filter paper stage: first wet and press the double-layer filter paper, then glue them together, and then dry and roll up the composite double-layer filter paper.

[0019] Technical effects and advantages of the present invention:

[0020] 1. In the present invention, the hot air blower collects hot air through a hot air collecting hood and conveys it through a blowing pipe into a U-shaped pipe, and outputs it through two output ends of the U-shaped pipe to blow dust on the side walls of the upper filter paper and the lower filter paper to be laminated, so as to avoid impurities inside them affecting the lamination quality and subsequent filtration efficiency during lamination. Moreover, hot air is blown onto the filter paper for preheating, and the preheated filter paper layers are laminated more tightly, reducing the phenomenon of filter element deformation caused by humid air. Part of the air is conveyed into the limiting pipe to intermittently fill the airbag, and the double-layer filter paper is gently vibrated by continuously filling the airbag. Combined with the wind speed blown out by the U-shaped pipe, thorough dust blowing treatment is carried out on the double-layer filter paper.

[0021] 2. In the present invention, first, the atomization area of the atomizing nozzle is controlled to correspond to the lamination area in the upper pressing roller, that is, after the atomizing nozzle sprays water, the upper pressing roller presses the double-layer filter paper in the wet area. Then, the gluing area in the upper glue pressing roller corresponds to the position of the glue spraying head, that is, after the glue spraying head sprays glue on the lower filter paper, the double-layer filter paper is glued through the cooperation of the upper glue pressing roller and the first resisting roller. First, the upper filter paper and the lower filter paper are fully pressed in a wet way to avoid separation of the filter paper after pressing, and then combined with the connection of glue to ensure the firmness of the double-layer filter paper lamination, that is, through the dual methods of wet pressing and glue adhesion to ensure the quality of the double-layer filter paper lamination.

[0022] 3. The present invention ensures the production quality of the filter element from two perspectives before and during the lamination of the double-layer filter paper. That is, before lamination, the bonding surface of the double-layer filter paper is blown with dust through a U-shaped pipe, and the filter paper is preheated with hot air to reduce the problem of filter element deformation caused by humid air. During lamination, first, the upper filter paper and the lower filter paper are fully pressed in a wet way, and then combined with the connection of glue to ensure the firmness of the double-layer filter paper lamination. Therefore, from the two perspectives of before and during, the production quality of the double-layer filter paper is jointly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1-Figure 8 As shown, in the prior art, in the case of humid environments such as the return of the south wind, the filter paper may be damp, resulting in the inability to better composite the double-layer filter paper, and the paper scraps and impurities above the double-layer filter paper will also affect the composite of the two. This problem can be solved by the following solution;

[0034] In this embodiment, a double-layer filter paper composite paper winding machine for manufacturing a vehicle filter comprises a frame 1 and a drying tool 2 installed in the middle thereof, a lower unwinding roller 3 and an upper unwinding roller 4 for conveying filter paper are respectively arranged on one side of the frame 1 from bottom to top, a winding roller 5 for winding the double-layer filter paper is arranged on the other side of the frame 1, and a filter paper pretreatment component 7 for dust removal of the double-layer filter paper is arranged between the lower unwinding roller 3 and the upper unwinding roller 4;

[0035] It should be noted that the drying tool 2 is a device in the prior art that has the function of drying the double-layer filter paper after gluing and pressing. It is a device in the prior art and will not be described in detail here. It is only necessary to have the drying function for the double-layer filter paper.

[0036] The filter paper pretreatment assembly 7 includes a hot air collection hood 71 arranged above the drying tool 2, a fan 72 is arranged on the top of the hot air collection hood 71, and the input end of the fan 72 is connected to the hot air collection hood 71, and the output end of the fan 72 is provided with a blowing pipe 73, and the output end of the blowing pipe 73 passes through the frame 1 and is connected to a U-shaped pipe 74, and the two output ends of the U-shaped pipe 74 are respectively arranged toward the bottom of the upper filter paper and the top of the lower filter paper, and a connecting pipe 75 is arranged in the middle of the U-shaped pipe 74, and a vibrating member 76 is arranged at the output end of the connecting pipe 75;

[0037] The drying device continues to work, and the fan 72 conveys the hot air through the hot air collecting cover 71 and the blowing pipe 73 to the U-shaped tube 74, and outputs it through the two output ends of the U-shaped tube 74, and performs dust blowing treatment on the side walls of the upper filter paper and the lower filter paper to be compounded, so as to prevent the impurities inside the two from affecting the compounding quality and subsequent filtration efficiency when the two are compounded, and the filter paper is preheated by blowing hot air, so that the preheated filter paper layer is more tightly attached, and the deformation of the filter element caused by humid air is reduced;

[0038] The vibrating member 76 includes a limiting tube 761 connected to the output end of the connecting tube 75. Two groups of blocking plates 763 are slidingly arranged inside the limiting tube 761. The two groups of blocking plates 763 are connected by tension springs. Both ends of the limiting tube 761 are sealed with air bags 765. The air bags 765 and the blocking plates 763 are connected by a pull rope 764. An air vent 762 is provided at the connection between the limiting tube 761 and the blocking plates 763.

[0039] In this embodiment, part of the air is transported to the interior of the limiting tube 761. As the air pressure inside the limiting tube 761 increases, the airbag 765 is continuously filled. Therefore, the airbag 765 pulls the blocking plate 763 outward through the pull rope 764. When the blocking plate 763 does not block the air leakage port 762, the gas is quickly released through the air leakage port 762. The two blocking plates 763 are quickly reset by the tension of the tension spring. The airbag 765 is continuously filled in a cycle. The double-layer filter paper is gently vibrated by the continuous filling of the airbag 765. In combination with the wind speed blown out by the U-shaped tube 74, the double-layer filter paper is thoroughly blown away.

[0040] Example 2: Please refer to Figure 1-Figure 5 As shown, the problem that it is difficult to ensure the firmness of the double-layer filter paper composite by only using glue can be solved by the following solution;

[0041] The input end of the drying tool 2 is provided with a double-layer filter paper composite assembly 6 for compounding two layers of filter paper; the double-layer filter paper composite assembly 6 includes an upper glue pressing roller 62 and an upper pressing roller 63 which are rotatably arranged above the frame 1, and the upper glue pressing roller 62 is located on one side of the drying tool 2, and a first resisting roller 61 for supporting and pressing the lower layer of filter paper is arranged directly below the upper glue pressing roller 62, and a second resisting roller 64 for supporting and pressing the lower layer of filter paper is arranged directly below the upper pressing roller 63, the first resisting roller 61 is connected to the frame 1, and both sides of the second resisting roller 64 are connected to the frame 1 through electric push rods 69;

[0042] A water spray rack 65 is provided on the side of the upper pressing roller 63 away from the upper glue pressing roller 62, and the water spray rack 65 is connected to the frame 1, and a water spray pipe 66 is provided below the water spray rack 65, and a plurality of atomizing nozzles 67 are provided at the output end of the water spray pipe 66, and a water supply pipe 68 is provided at the input end of the water spray pipe 66, and glue is supplied to the glue spray head 611 through an external water supply tool; it should be supplemented here that: the glue pressing area in the upper glue pressing roller 62 corresponds to the position of the glue spray head 611, that is, after the glue spray head 611 is glued to the lower filter paper, the upper glue pressing roller 62 and the first resisting roller 61 cooperate to complete the gluing of the double-layer filter paper; and the glue pressing area and the glue spray head 611 in the upper glue pressing roller 62 are both installed by bolts and can be adjusted, thereby changing their positions, thereby improving the flexibility of equipment use;

[0043] The atomizing area of ​​the atomizing nozzle 67 is controlled to correspond to the position of the pressing area in the upper pressing roller 63, that is, after the atomizing nozzle 67 sprays water, the upper pressing roller 63 presses the double-layer filter paper in the slippery area; therefore, in this embodiment, the upper filter paper and the lower filter paper are fully pressed together by a wet method to avoid separation of the filter paper after pressing, and then the connection is combined with glue to ensure the firmness of the double-layer filter paper composite, that is, the quality of the double-layer filter paper composite is ensured by the dual methods of wet pressing and glue bonding;

[0044] A glue spraying rod 610 is also provided above the frame 1, and the glue spraying rod 610 is located in the middle of the double-layer filter paper. Two glue spraying heads 611 are connected to the glue spraying rod 610 by bolts. The output end of the glue spraying head 611 is arranged toward the filter paper of the lower layer. The glue spraying heads 611 are connected by a connecting hose 612, and the glue spraying heads 611 are supplied with glue by an external glue supply tool.

[0045] In the present invention, it can be seen from the combination of Example 1 and Example 2 that the production quality of the filter element is ensured from two perspectives: before and during the compounding of the double-layer filter paper, the dust is blown off the bonding surface of the double-layer filter paper through the U-shaped tube 74 before the compounding, and the filter paper is preheated by hot air to reduce the deformation of the filter element caused by humid air. During the compounding, the upper filter paper and the lower filter paper are fully pressed together in a wet manner, and then connected with glue to ensure the firmness of the double-layer filter paper compounding. Therefore, from the two perspectives, the production quality of the double-layer filter paper is improved together;

[0046] Working principle:

[0047] Step 1, pretreatment: the drying device keeps working, and the fan 72 conveys the hot air through the hot air collecting cover 71 and the blowing pipe 73 to the U-shaped tube 74, and outputs it through the two output ends of the U-shaped tube 74, and performs dust blowing treatment on the side walls of the upper filter paper and the lower filter paper to be compounded, so as to prevent the impurities inside from affecting the compounding quality and subsequent filtration efficiency when the two are compounded, and the filter paper is preheated by blowing hot air, so that the preheated filter paper layer is more closely attached, and the deformation of the filter element caused by humid air is reduced;

[0048] Part of the air is transported to the inside of the limit tube 761. As the air pressure inside the limit tube 761 increases, the airbag 765 is continuously filled. Therefore, the airbag 765 pulls the blocking plate 763 outward through the pull rope 764. When the blocking plate 763 does not block the air leakage port 762, the gas is quickly released through the air leakage port 762. The two blocking plates 763 are quickly reset by the tension of the tension spring. The airbag 765 is continuously filled in a cycle. The double-layer filter paper is gently vibrated by the continuous filling of the airbag 765. With the wind speed blown out by the U-shaped tube 74, the double-layer filter paper is thoroughly blown away.

[0049] Step 2: Compound:

[0050] First pressing: the atomizing area of ​​the atomizing nozzle 67 is controlled to correspond to the position of the pressing area in the upper pressing roller 63, that is, after the atomizing nozzle 67 sprays water, the upper pressing roller 63 presses the double-layer filter paper in the slippery area;

[0051] Post-gluing: The glue pressing area in the upper glue pressing roller 62 corresponds to the position of the glue spraying head 611, that is, after the glue spraying head 611 sprays glue on the lower filter paper, the upper glue pressing roller 62 cooperates with the first resisting roller 61 to complete the gluing of the double-layer filter paper; first, the upper filter paper and the lower filter paper are fully pressed together in a wet manner to avoid separation of the filter paper after pressing, and then the connection is carried out with glue to ensure the firmness of the double-layer filter paper composite, that is, the quality of the double-layer filter paper composite is ensured by the dual methods of wet pressing and glue bonding;

[0052] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
