Description

Technical Field

[0001] This utility model relates to the technical field of filter paper processing, specifically to a double-crease filter paper folding machine. Background Technology

[0002] Currently, the main raw material in the manufacturing process of air filters for automotive engines is special creasing and folding filter paper. The function of this filter element is to filter and purify the engine intake air before it enters the engine, preventing particulate matter from being drawn into the engine, reducing carbon deposits left over from combustion, and extending the engine's lifespan. In the filter element manufacturing process, the special filter paper needs to be pressed into a concave-convex shape and creasing and folded using a rolling mill. After folding, the concave-convex contact between the paper sheets mainly controls the gaps between the folded sheets, indirectly controlling the filter area and the product's appearance.

[0003] Chinese Patent CN210733445U discloses a filter paper creasing and folding device for a filter element. Its key technical features include two fixed plates, with a first creasing roller, a second creasing roller, and a positioning roller positioned between them. The first and second creasing rollers are arranged vertically and driven by gear meshing. The first creasing roller can move vertically. The first and second creasing rollers are tangent to each other and each has an annular concave surface, an annular convex surface, and creasing knives. Multiple annular concave surfaces and multiple annular convex surfaces are spaced apart along the axial direction of their respective creasing rollers. Multiple creasing knives are evenly distributed along the circumference of their respective creasing rollers and extend axially. Each creasing knife on the second creasing roller includes two trapezoidal corrugated creasing knife bodies, with their crests corresponding and forming an olive-shaped space, and their troughs corresponding and fitting together.

[0004] In the above scheme, by passing the filter paper between the first and second creasing rollers and then creasing the filter paper with the creasing knife on them, the following disadvantages occur: the filter paper cannot be pressed tightly before creasing, which will result in wrinkles or looseness, making the surface of the filter paper not flat enough when it enters the creasing area. Utility Model Content

[0005] The purpose of this invention is to provide a double-crease filter paper folding machine to solve the problem that the filter paper cannot be pressed tightly before creasing, which will result in wrinkles or looseness, making the surface of the filter paper not flat enough when it enters the creasing area.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a double-crease filter paper folding machine, including an upper creasing roller, which is rotatably disposed inside a mounting frame. A lower creasing roller is rotatably disposed inside the mounting frame. A first drive motor is provided at the right end of the upper creasing roller. A second drive motor is fixed to the right side of the outer wall of the mounting frame. The output shaft of the second drive motor passes through the mounting frame and is fixedly connected to the right end of the lower creasing roller. Several creasing knives are fixed to the outer walls of both the upper and lower creasing rollers. A lower pressure roller is rotatably disposed inside the mounting frame. Movable holes are respectively opened on the left and right sides of the outer wall of the mounting frame. Movable seats are movably disposed inside the two movable holes. An upper pressure roller is rotatably disposed between the two movable seats.

[0007] Preferably, a first electric push rod is detachably installed inside each of the two movable holes, and one end of the telescopic rod of each of the two first electric push rods is fixedly connected to the top surface of the two movable seats.

[0008] Preferably, the inner walls of the two movable holes are provided with sliding grooves on the front and rear sides, and the two movable seats are fixed with sliders on the front and rear sides, and the two sliders are slidably disposed in the two sliding grooves.

[0009] Preferably, the top surface of the mounting bracket is provided with a plurality of threaded grooves, and the top surfaces of the two first electric push rods are respectively fixed with mounting plates. The top surfaces of the two mounting plates are respectively provided with two threaded holes, and bolts are threadedly connected to the two threaded holes. The threaded ends of the bolts are threadedly connected to the inside of the threaded grooves.

[0010] Preferably, the outer wall of the mounting bracket has connection holes on the left and right sides respectively, and mounting seats are movably disposed inside the two connection holes. The upper indentation roller is rotatably disposed between the two mounting seats. The first drive motor is fixed on the right side of the right mounting seat. The output shaft of the first drive motor passes through the mounting seat and is fixedly connected to the right end of the upper indentation roller. Second electric push rods are fixed inside the two connection holes respectively, and one end of the telescopic rods of the two second electric push rods is fixedly connected to the top surface of the two mounting seats respectively.

[0011] Preferably, the mounting frame is rotatably provided with a positioning roller inside, and two positioning rings are fixed to the outer wall of the positioning roller.

[0012] Compared with existing technologies, the double-crease filter paper folding machine that adopts the above technical solution has the following beneficial effects:

[0013] 1. In use, the coordinated use of the upper indentation roller, mounting frame, lower indentation roller, first drive motor, second drive motor, indentation knife, lower pressure roller, moving seat and upper pressure roller facilitates double indentation treatment of filter paper, and at the same time can press the filter paper tightly to prevent wrinkles or looseness, ensuring that the surface of the filter paper is flat when entering the indentation area, thus improving the indentation quality of the filter paper;

[0014] Second, during use, activating the first electric push rod causes the movable seat to rise and fall, which in turn drives the upper pressure roller to adjust its height, thereby adjusting the distance between the upper and lower pressure rollers. This allows for the pressing of filter paper of different thicknesses, improving the flexibility and practicality of the device. The cooperation between the slide groove and the slider helps to limit the movement of the movable seat, ensuring that it will not deviate or shake during lifting and lowering, thus improving the stability of the movable seat during lifting and lowering.

[0015] Thirdly, during use, the use of threaded grooves, mounting plates, threaded holes, and bolts facilitates the disassembly and assembly of the first electric push rod, moving seat, and upper pressure roller, making maintenance or replacement convenient. The distance between the upper and lower pressure rollers can be adjusted, allowing for pressure creasing of filter paper of different thicknesses, improving the flexibility and practicality of the device. It effectively prevents filter paper misalignment during transport, ensuring accurate entry into subsequent folding processes. Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the double-creased filter paper folding machine includes an upper creasing roller 1, which is rotatably mounted inside a mounting frame 2. A lower creasing roller 3 is rotatably mounted inside the mounting frame 2. A first drive motor 4 is provided at the right end of the upper creasing roller 1. A second drive motor 5 is fixed to the right side of the outer wall of the mounting frame 2. The output shaft of the second drive motor 5 passes through the mounting frame 2 and is fixedly connected to the right end of the lower creasing roller 3. Several creasing knives 6 are fixed to the outer walls of both the upper creasing roller 1 and the lower creasing roller 3. A lower pressure roller 7 is rotatably mounted inside the mounting frame 2. Movable holes 8 are opened on the left and right sides of the outer wall of the mounting frame 2. Movable seats 9 are movably mounted inside the two movable holes 8. An upper pressure roller 10 is rotatably mounted between the two movable seats 9.

[0023] In operation, the operator first passes the filter paper from the unwinding device (not shown in the diagram) through the gap between the lower pressure roller 7 and the upper pressure roller 10. This presses the filter paper firmly, preventing wrinkles or looseness and ensuring a smooth surface. Next, the paper passes between the upper creasing roller 1 and the lower creasing roller 3. The operator then activates the first drive motor 4 and the second drive motor 5, causing the upper and lower creasing rollers 1 and 3 to rotate in opposite directions, conveying the front of the mounting frame 2. Simultaneously, the creasing knives 6 on the upper and lower creasing rollers 1 and 3 respectively creasing the top and bottom surfaces of the filter paper, achieving a double creasing effect. The coordinated use of the upper creasing roller 1, mounting frame 2, lower creasing roller 3, first drive motor 4, second drive motor 5, creasing knives 6, lower pressure roller 7, moving seat 9, and upper pressure roller 10 facilitates double creasing of the filter paper, ensuring it is pressed firmly to prevent wrinkles or looseness and guaranteeing a smooth surface upon entering the creasing area, thus improving the creasing quality of the filter paper.

[0024] like Figures 1-4 As shown, the two movable holes 8 are respectively provided with a first electric push rod 11, and one end of the telescopic rod of the two first electric push rods 11 is fixedly connected to the top surface of the two movable seats 9.

[0025] In use, by activating the first electric push rod 11, the movable seat 9 is raised and lowered, which in turn drives the upper pressure roller 10 to adjust its height, thereby adjusting the distance between the upper pressure roller 10 and the lower pressure roller 7. This allows for the pressing of filter paper of different thicknesses, improving the flexibility and practicality of the device.

[0026] like Figures 1-4As shown, the inner walls of the two movable holes 8 are provided with sliding grooves 12 on the front and rear sides respectively. The two movable seats 9 are fixed with sliders 13 on the front and rear sides respectively. The two sliders 13 are slidably arranged in the two sliding grooves 12 respectively. The top surface of the mounting bracket 2 is provided with several threaded grooves 14. The top surfaces of the two first electric push rods 11 are respectively fixed with mounting plates 15. The top surfaces of the two mounting plates 15 are respectively provided with two threaded holes 16. The two threaded holes 16 are respectively threaded with bolts 17. The threaded end of the bolt 17 is threadedly connected to the inside of the threaded groove 14.

[0027] During use, the cooperation of the slide groove 12 and the slider 13 helps to limit the movement of the moving seat 9, ensuring that it will not deviate or shake during lifting and lowering, thus improving the stability of the moving seat 9 during lifting and lowering. The cooperation of the threaded groove 14, the mounting plate 15, the threaded hole 16 and the bolt 17 facilitates the disassembly and assembly of the first electric push rod 11, the moving seat 9 and the upper pressure roller 10 by the operators, making it convenient for maintenance or replacement.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the outer wall of the mounting frame 2 has connection holes 18 on the left and right sides respectively. The two connection holes 18 are respectively movably provided with mounting seats 19. The upper indentation roller 1 is rotatably disposed between the two mounting seats 19. The first drive motor 4 is fixed on the right side of the right mounting seat 19. The output shaft of the first drive motor 4 passes through the mounting seat 19 and is fixedly connected to the right end of the upper indentation roller 1. The two connection holes 18 are respectively fixed with second electric push rods 20. One end of the telescopic rod of the two second electric push rods 20 is fixedly connected to the top surface of the two mounting seats 19 respectively. The mounting frame 2 is rotatably provided with a positioning roller 21. The outer wall of the positioning roller 21 is fixed with two positioning rings 22.

[0029] In use, activating the second electric push rod 20 allows the mounting base 19 to be raised and lowered, thereby moving the upper creasing roller 1 up and down. This adjusts the distance between the upper creasing roller 1 and the lower creasing roller 3, enabling creasing of filter paper of different thicknesses and improving the flexibility and practicality of the device. After the filter paper is creasing by the upper creasing roller 1 and the lower creasing roller 3, it is conveyed towards the front of the mounting frame 2 onto the positioning roller 21. At this time, the positioning ring 22 limits the left and right sides of the filter paper, effectively preventing the filter paper from shifting during conveying and ensuring that the filter paper accurately enters the subsequent folding process.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
