Description

Technical Field

[0001] The utility model relates to the field of filter screen production and processing, in particular to a blade-type creasing device for raw materials used in processing filter screens. Background Art

[0002] In the filter screen manufacturing industry, filter paper is a key material, and its processing process is crucial for the quality and performance of the final product. In subsequent applications, such as components of air purifiers or liquid filters, filter paper often needs to be manually cut into small pieces of specific sizes or shapes. To facilitate this manual cutting process, a series of creases are pre-formed in the filter paper during production. These creases not only serve as physical markers to guide users to tear the filter paper along a specific path but also enhance the structural strength of the filter paper during cutting, reducing irregularities and breakage rates during the tearing process.

[0003] In existing filter paper creasing processing equipment, a common method is to adopt blade-type technology. This technology controls the up-and-down movement of the blade in the vertical direction, so that a series of parallel stripes are left on the surface of the filter paper by the edge of the blade, thereby forming creases. During operation, the filter paper is smoothly conveyed under the blade, and the blade moves rapidly up and down along a preset trajectory, contacts the filter paper, and leaves clear crease marks.

[0004] When the blade contacts the filter paper, the filter paper bends and shrinks from both ends towards the turning point. One side of the filter paper is the feeding roller for feeding, and the other side is in a relaxed state. The part leaving the workbench droops, and its own weight generates a pulling force on the filter paper on the workbench, which may pull the filter paper, thus causing an error in the crease spacing. Moreover, for filter papers of different sizes, the narrower filter paper may slide left and right, affecting the quality of the creases. Content of the Utility Model

[0005] In order to overcome the disadvantage that the crease quality cannot be guaranteed, the utility model provides a blade-type accurate creasing device for raw materials used in processing filter screens.

The creasing assembly controls the up-and-down movement of the blade to perform indentation processing on the filter paper. It also includes a frame assembly, a motor, gears, a chain, a first roller, an up-and-down adjustment assembly, and a left-and-right adjustment assembly. The motor is installed on the left side of the top of the lathe. The frame assembly is installed on the left and right sides of the top of the lathe and is divided into front and rear groups.

An up-and-down adjustment assembly for adjusting the vertical gap between the first rollers is arranged on the frame assembly, and a left-and-right adjustment assembly for restricting the passing width of the filter paper is arranged on the lathe.

[0007] Optionally, the frame assembly includes an upper frame, a lower frame, and a connecting block. A plurality of lower frames are connected to the left and right sides of the lathe. A connecting block is connected to one end of the lower frame close to the creasing assembly. The upper frame is rotatably connected to the connecting block. First rollers are arranged between the upper frames, and first rollers are rotatably connected between the lower frames. The chain is located inside the lower frame.

The first rollers on the upper frame are all rotatably connected to the slider. The first screw is threadedly connected to the slider and is rotatably connected to the upper frame. A pulley is fixedly connected to the first screw, and first screws are arranged on the front and rear sides of the slider at both ends of the first roller. The belt is sleeved on the pulleys in sequence, and the four first screws are connected by the belt.

[0009] Optionally, the left-and-right adjustment assembly includes a limiting plate, a limiting rod, and a second screw. The two ends of the limiting rod are fixedly connected to the bottom of the lower frame. The second screw is rotatably connected to the middle of the bottom of the lower frame. The limiting plate is slidably connected to the limiting rod, and the limiting plate is threadedly connected to the second screw.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following describes the embodiments of the present utility model with reference to the accompanying drawings.

[0026] Embodiment: A blade-type creasing device for processing raw materials for filter meshes, as Figures 1-7As shown in the figure, it includes a lathe 1. The lathe 1 includes a support frame, a workbench and a creasing assembly. The creasing assembly controls the up and down movement of the blade to perform indentation processing on the filter paper. It also includes a frame assembly 2, a motor 3, a gear 4, a chain 5, a first over-roller 6, an up and down adjustment assembly and a left and right adjustment assembly. The motor 3 is installed on the left side at the top of the lathe 1. The frame assembly 2 is installed on the left and right sides at the top of the lathe 1 and is divided into front and rear groups. Eight first over-rollers 6 are rotatably connected between the frame assemblies 2 of the same group, and the first over-rollers 6 are divided into upper and lower layers. The left end of the first over-roller 6 is connected to a gear 4. A chain 5 is arranged inside the frame assembly 2, and the chain 5 meshes with the four gears 4 on the first over-rollers 6 connected to the frame assembly 2 of the same group. The output shaft of the motor 3 is also connected to a gear 4, and the gear 4 connected to the motor 3 meshes with the chain 5. An up and down adjustment assembly for adjusting the vertical gap between the first over-rollers 6 is arranged on the frame assembly 2, and a left and right adjustment assembly for restricting the passing width of the filter paper is arranged on the lathe 1.

[0027] As Figure 3 , Figure 4 and Figure 6 shown, the frame assembly 2 includes an upper frame 201, a lower frame 202 and a connecting block 203. Four lower frames 202 are connected to the left and right sides of the lathe 1. A connecting block 203 is connected to one end of each lower frame 202 close to the creasing assembly. The upper frame 201 is rotatably connected to the connecting block 203. Four first over-rollers 6 are arranged between the upper frames 201, and four first over-rollers 6 are rotatably connected between the lower frames 202. The chain 5 is located inside the lower frame 202, and the rear frame assembly 2 is used to convey the filter paper forward.

[0028] As Figure 3 , Figure 4 and Figure 7 shown, the up and down adjustment assembly includes a first screw 7, a slider 8, a pulley 9 and a belt 10. A slider 8 is slidably connected to the middle of the upper frame 201. The first over-rollers 6 on the upper frame 201 are all rotatably connected to the slider 8. The first screw 7 is threadedly connected to the slider 8 and is rotatably connected to the upper frame 201. A pulley 9 is fixedly connected to the first screw 7, and first screws 7 are arranged on the front and rear sides of the sliders 8 at both ends of the first over-roller 6. The belt 10 is sleeved on the pulleys 9 in sequence, and the four first screws 7 are connected by the belt 10. A nut for convenient screwing is arranged on one of the first screws 7.

[0029] As Figure 2 , Figure 3 and Figure 5 shown, the left and right adjustment assembly includes a limit plate 11, a limit rod 12 and a second screw 13. The two ends of the limit rod 12 are fixedly connected to the bottom of the lower frame 202. The second screw 13 is rotatably connected to the middle of the bottom of the lower frame 202. The limit plate 11 is slidably connected to the limit rod 12, and the limit plate 11 is threadedly connected to the second screw 13.

[0030] The staff member opens the frame assembly 2. After one end of the filter paper passes through the frame assembly 2, it is wound around the winding device. Subsequently, the lathe 1 and the motor 3 are started. The blade of the creasing assembly in the lathe 1 moves up and down to perform indentation processing on the passing filter paper. Thus, after the filter paper passes through, a series of creases are left. The motor 3 drives the chain 5 to rotate through the gear 4 connected to it, and then drives other first rollers 6 equipped with gears 4, so that all the first rollers 6 at the bottom rotate, conveying the filter paper forward. And according to the thickness of the filter paper, the staff member adjusts the height of the upper first roller 6 through the up-and-down adjustment assembly. According to the width of the filter paper, the passing width of the filter paper is restricted through the left-and-right adjustment assembly, so that during the creasing process of the filter paper, the uniformity and accuracy of the creases can be ensured;

[0031] Regarding the opening and closing process of the frame assembly 2, it should be added that: The staff member flips up the upper frame 201, and the upper frame 201 rotates around the connecting piece and separates from the lower frame 202. Since the frame assembly 2 is adjacent to the creasing assembly, when lifting the upper frame 201, a position far from the creasing assembly is selected. After the filter paper passes through the frame assembly 2 at the rear end, it immediately contacts the first roller 6 connected to the front-end frame assembly 2, and the distance in the middle is short. Thus, relying on the hardness of the filter paper, it can support itself to pass through the two first rollers 6. The staff member pulls out the filter paper from the front end, and then puts down the upper frame 201;

[0032] Regarding the adjustment process of the up-and-down adjustment assembly, it should be added that: Since the frame assembly 2 at the rear end needs to provide stable conveying capacity, and the frame assembly 2 at the front end, during the folding process, due to the movement of the filter paper, needs to move backward a certain distance. Thus, the up-and-down adjustment assembly is only located on the frame assembly 2 at the rear end. When it is necessary to adjust the distance between the upper and lower parts of the first rollers 6, turn the first screw 7. The first screw 7 drives the pulley 9 to rotate, and after being transmitted through the belt 10, all the first screws 7 at the rear end rotate in the same direction. Since the first screws 7 are respectively connected to the upper frame 201 and the slider 8, the up-and-down position of the slider 8 can be controlled, thereby adjusting the height of the first roller 6 connected to the slider 8, so that the filter paper can be clamped, ensuring that the filter paper at the rear end can remain stable when the creasing assembly works, and thus ensuring the uniformity of the crease spacing;

[0033] Regarding the adjustment process of the left-and-right adjustment assembly, it should be added that: When the width of the filter paper is small, turn the second screw 13. The right end of the second screw 13 is connected with a nut, which is convenient for turning the second screw 13. The rotating second screw 13 drives the limiting plate 11 to move towards the middle. The limiting plate 11 moves parallel along the limiting rod 12, thereby shortening the effective distance of the first roller 6, making it difficult for the filter paper to move left and right or bend, ensuring that the filter paper can remain parallel when passing through, and thus ensuring the quality of the creases.

[0034] Such as Figure 4 AndFigure 6 As shown in the figure, it further includes a pin 14 and a torsion spring 17. The pin 14 is slidably connected to one end of the upper frame 201 away from the crease assembly and is in interference fit with the lower frame 202. The torsion spring 17 is sleeved on the connecting block 203, with one end connected to the upper frame 201 and the other end connected to the connecting block 203.

[0035] The pin 14 can stabilize the states of the upper frame 201 and the lower frame 202, and can also reduce the production quality of the upper frame 201 and the lower frame 202. When opening the upper frame 201, the pin 14 is pulled out. Under the action of the torsion of the torsion spring 17, the upper frame 201 naturally opens at a certain angle, which is convenient for the staff to reach into the space between the first over rollers 6 on the upper and lower layers. Since the pin 14 is in interference fit with the lower frame 202, the frictional force between the pin 14 and the lower frame 202 is greater than the elastic force of the torsion spring 17. Therefore, after the pin 14 is inserted, the upper frame 201 cannot rotate and unfold.

[0036] As Figure 1 and Figure 2 shown in the figure, it further includes a dust-proof net 15. The dust-proof net 15 is connected to the top of the upper frame 201 and covers all the first over rollers 6.

[0037] The dust-proof net 15 can keep the first over rollers 6 clean for a long time, so as to ensure that when transporting the filter paper, the frictional force of the first over rollers 6 on the filter paper can be guaranteed and the surface of the filter paper will not be damaged.

[0038] As Figure 3 and Figure 5 shown in the figure, it further includes a second over roller 16. The second over roller 16 is vertically and rotatably connected to the inside of the limit plate 11 and is located on the side where the limit plate 11 contacts the filter paper.

[0039] When the filter paper passes through the limit plate 11, it contacts the second over roller 16, changing the sliding friction to rolling friction, thereby reducing the damage to the edge of the filter paper.

[0040] As Figure 1 and Figure 2 shown in the figure, it further includes a telescopic support rod 18. The telescopic support rod 18 is slidably connected to the front and rear ends of the lathe 1 and is used to extend the working length of the filter paper.

[0041] Pull out the telescopic support rod 18 to both sides. The filter paper bends at the telescopic support rod 18 and is at the same height as the first over roller 6, which can reduce the tension on the first over rollers 6 at both ends and contribute to the stable transportation of the first over roller 6.

[0042] The above are only the 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 shall be included within the protection scope of the present invention.
