Description

Technical Field

[0001] The invention relates to the field of manufacturing filter paper for filter element, and in particular to a paper stacking type automatic paper press for filter paper. Background Art

[0002] The function of the fuel filter is to filter out harmful particles and water in the engine fuel gas system to protect the oil pump nozzle, cylinder liner, piston ring, etc., reduce wear and avoid clogging, remove solid debris such as iron oxide and dust contained in the fuel, prevent clogging of the fuel system, reduce mechanical wear, ensure stable operation of the engine, and improve reliability. Even if the diesel is clean after precipitation and filtration before being added to the diesel engine tank, it will still be contaminated by factors such as refueling tools, refueling environment, and unclean tank opening during refueling. In addition, during the operation of the diesel engine, the impurities deposited in the fuel system and the suspended dust in the air will also contaminate the diesel. Therefore, the diesel filter on the vehicle is indispensable, not to mention that the diesel is not necessarily really clean before being added to the tank. There are three types of fuel filters: diesel filters, gasoline filters, and natural gas filters.

[0003] The filters currently widely used in fuel engines have low filtering accuracy and large oil flow resistance. The fuel contains a large amount of impurities. During use, the filters are often blocked, causing the filters to not work properly, and then the fuel cannot enter the fuel engine, causing the fuel engine to fail to operate.

[0004] The main filtering component in the filter is the filter element. The filter paper in the existing filter element is folded and arranged in a ring shape outside the center tube of the filter element. The folding is to increase the filtering area, but the filtering area of ​​this type of filter paper is still small. A stacked filter paper has appeared on the market, that is, the cross-section of the filter paper is set to match the inner diameter of the two end covers and then stacked and sleeved on the center tube in sequence to form a stacked filter element. Each piece of filter paper in this filter element is provided with a filtering hole. After stacking, it is ensured that the fuel can flow through normally, but impurities will be retained between adjacent filter papers.

[0005] However, in the prior art, the production method for this type of filter paper is to use a stamping device to first stamp the shape of the entire stack of filter paper, then stamp the filter holes and then stamp the center hole, or stamp the center hole while stamping the filter holes or stamp the filter holes while stamping the center hole. This step-by-step molding method not only has a complicated process but also requires a large investment in equipment and has low processing efficiency. Summary of the invention

[0006] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art.

[0007] Provides automatic paper press for stacking filter paper.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a paper stacking type automatic paper press for filter paper, comprising a frame, characterized in that: the frame is provided with archways set up relatively to each other, at least one group of paper feed traction roller group, forming traction roller group and at least one group of paper discharge traction roller group are arranged between the two archways, the paper feed traction roller group comprises a paper feed traction active roller and a paper feed traction passive roller, the forming traction roller group comprises a forming traction active roller and a forming traction passive roller, the paper discharge traction roller group comprises a paper discharge traction active roller and a paper discharge traction passive roller, and a paper passing gap for filter paper to pass through is formed between the paper feed traction active roller and the paper feed traction passive roller, between the forming traction active roller and the forming traction passive roller, and between the paper discharge traction active roller and the paper discharge traction passive roller, a driving mechanism is arranged below the frame, one end of the paper feed traction active roller, the forming traction active roller and the material discharge traction active roller all pass through the archway and are synchronously driven by the driving mechanism through a synchronization mechanism, and a molding structure that can simultaneously mold the filter paper shape, the filter paper center hole and the filter paper filter hole is arranged on the molding traction active roller.

[0009] By adopting the above technical scheme, the paper can be fed in by placing the filter paper roll on the unwinding rack and then one end of the roll passes through the paper feed traction roller group and enters the paper press. The paper feed traction active roller and the paper feed traction passive roller in the paper feed traction roller group are distributed up and down, the forming traction active roller and the forming traction passive roller in the forming traction roller group are distributed up and down, and the paper outlet traction active roller and the paper outlet traction passive roller in the paper outlet traction roller group are distributed up and down. A gap is formed between each group for the filter paper to pass through. The driving mechanism drives the paper feed traction active roller, the forming traction active roller, and the paper outlet traction active roller to rotate simultaneously through the synchronization mechanism. When the filter paper passes through, one side of the filter paper is moved between the paper feed traction active roller, the forming traction active roller, and the paper outlet traction active roller. The other side of the roller moves forward under the traction of the paper feeding traction passive roller, the forming traction passive roller, and the paper discharging traction passive roller to rotate. When the filter paper passes through the forming traction roller group, since the forming traction active roller is provided with a forming structure that can simultaneously form the filter paper shape, the filter paper center hole and the filter paper filter hole, the filter paper will be rolled out of the filter paper shape and the filter paper center hole and the filter paper filter hole under the action of the forming structure. Of course, the forming structures can also be set separately, and only the forming structure for forming the filter paper shape is set on the forming traction active roller, and the forming structure for forming the filter paper center hole and the filter paper filter hole is set on the forming traction passive roller. This method is only different from the present scheme in terms of arrangement and combination.

[0010] The above-mentioned automatic paper pressing machine for stacking filter paper of the filter can be further configured as follows: the molding structure includes at least one group of first embossings that are arranged at both ends of the molding traction active roller or one end thereof and are connected end to end in a ring shape and are consistent with the shape of one side of the filter paper to be molded; the other end of the molding traction active roller opposite to the first embossing is provided with a second embossing that is consistent with the shape of the other side of the filter paper to be molded; a center hole embossing in the shape of a hollow triangle is provided between the first embossing and the second embossing; the first embossing and the second embossing are provided with a first filter hole embossing, a second filter hole embossing and a third filter hole embossing that are distributed in a triangular shape in the circumferential direction of the center hole embossing; and crease embossings that are relatively arranged are provided on both sides of the center hole embossing.

[0011] By adopting the above technical scheme, multiple groups of first embossings and multiple groups of second embossings can be set according to the different lengths of the forming traction active rollers. For example, when two groups of filter papers are to be formed at one time, two groups of first embossings can be set, and the second embossings can be set between the two groups of first embossings. For more than two groups, it is sufficient to set them according to the ratio of the first embossing to the second embossing of 2:1. The shape of the filter paper is pressed out by the first embossing and the second embossing, and the center hole is pressed out by the hollow triangle center hole embossing for the penetration of the center tube. Three filter holes are pressed out by the first filter hole embossing, the second filter hole embossing and the third filter hole embossing distributed in a triangle, and then creases are pressed out by the crease embossing set on both sides of the center hole. The raw material of the filter paper is not cut after passing through the forming traction roller group, but can be folded along the creases pressed out by the crease embossing, and the filter paper can be stacked along the creases according to the length of the filter element. The whole filter paper is not cut, the processing efficiency is higher, and the filter element production is faster and more convenient.

[0012] The above-mentioned automatic paper pressing machine for stacking filter paper can be further configured as follows: the first embossing, the second embossing, the center hole embossing, the first filter hole embossing, the second filter hole embossing, and the third filter hole embossing are all in the shape of an acute-angled triangle at the other end of the traction active roller connected to the forming part, and the crease embossing is in the shape of an obtuse-angled triangle at the other end of the traction active roller connected to the forming part.

[0013] By adopting the above technical scheme, the other end of the traction active roller where the first embossing, the second embossing, the center hole embossing, the first filter hole embossing, the second filter hole embossing and the third filter hole embossing are relatively connected to form an acute triangle shape. The edge of the acute triangle is sharp, and the filter paper can be directly cut into a shape consistent with the first embossing, the second embossing, the center hole embossing, the first filter hole embossing, the second filter hole embossing and the third filter hole embossing. The other end of the traction active roller where the crease embossing is relatively connected to form a blunt-angled triangle shape. Since the crease embossing does not need to be cut, it is set to an obtuse triangle shape to prevent the filter paper from being cut.

[0014] The above-mentioned automatic paper pressing machine for folding filter paper can be further configured as follows: the plane where the other end of the fold embossing is relatively connected to the forming traction active roller is located is lower than the plane where the other end of the first embossing, the second embossing, the center hole embossing, the first filter hole embossing, the second filter hole embossing, and the third filter hole embossing are relatively connected to the forming traction active roller.

[0015] By adopting the above technical scheme, such an arrangement not only ensures the cutting effect of the first embossing, the second embossing, the center hole embossing, the first filter hole embossing, the second filter hole embossing and the third filter hole embossing, but also ensures the crease effect of the crease embossing.

[0016] The above-mentioned paper stacking automatic paper press for filter paper can be further configured as follows: the driving mechanism is a motor, a mounting seat is provided under the frame, a gear box is provided on the mounting seat, a first transmission shaft is provided on the gear box, the motor is provided at one end of the gear box and drives the first transmission shaft to rotate through the gear, and the synchronization mechanism includes a second transmission shaft arranged at the other end of the frame opposite to the archway, the second transmission shaft is installed on the frame through a relatively arranged mounting plate and a second synchronous wheel is arranged at one end, a first synchronous wheel is provided on the first transmission shaft and is in the same plane as the second synchronous wheel, and the first synchronous wheel and the second synchronous wheel are synchronously driven by a synchronous belt, the frame is provided with a transmission box at the synchronous belt, a transmission mounting seat is provided in the transmission box, and passive shafts with the same number as the paper feeding traction roller group, the forming traction roller group and the discharging traction roller group are distributed on the transmission mounting seat at intervals, and one end of the passive shaft The transmission box passes through the transmission box and is provided with a first synchronous gear. One end of the paper feed traction active roller, the forming traction active roller and the material discharging traction active roller passes through the archway and is provided with a second synchronous gear meshing with the first synchronous gear. The second transmission shaft is provided with a first synchronous sprocket between the two mounting plates. The driven shaft near the paper feed traction active roller is provided with a second synchronous sprocket at the plane where the first synchronous sprocket is located, and the driven shaft near the forming traction active roller is provided with a third synchronous sprocket at the plane where the first synchronous sprocket is located. The first synchronous sprocket, the second synchronous sprocket and the third synchronous sprocket are synchronously driven by the first chain. The third synchronous sprocket is a double-row sprocket. A fourth synchronous sprocket is provided on the driven shaft near the paper discharging traction active roller. The fourth synchronous sprocket and the other row of teeth of the third synchronous sprocket connected to the first chain are in the same plane, and the fourth synchronous sprocket and the third synchronous sprocket are synchronously driven by the second chain.

[0017] By adopting the above technical solution, the synchronous rotation among the paper feeding traction active roller, the forming traction active roller and the paper discharging traction active roller is achieved through the motor, the transmission box, the gear box, the synchronous wheel and the synchronous sprocket.

[0018] The beneficial effects of the present invention are: simplifying the processing method of the stacked paper filter element and increasing the processing efficiency, thereby greatly reducing the investment in processing equipment.
