[0001] This utility model relates to the field of filter cotton cutting technology for capsule filters, specifically to a non-woven filter cotton cutting device. Background Technology
[0002] Non-woven filter cotton, a key material in air purification, effectively intercepts airborne particulate matter due to its unique fibrous mesh structure, and is widely used in various scenarios such as air conditioning pre-filters, paint spray booths, and fan handling units. In the field of capsule filters, non-woven filter cotton has become one of the core filter materials due to its excellent filtration performance, cost advantage, and processability. Capsule filters, with their small footprint, easy replacement, and high filtration efficiency, are widely used in fluid filtration in industries such as biopharmaceuticals, food and beverage, and electronics semiconductors. The cutting precision and quality of the filter cotton directly affect the sealing performance, filtration efficiency, and service life of capsule filters.
[0003] However, current nonwoven filter cotton cutting devices require two separate cuts to cut the nonwoven filter cotton suitable for capsule filters, which reduces cutting efficiency and makes the finished product mixed with waste, making recycling difficult. Utility Model Content
[0004] The present invention aims to solve the problems mentioned in the background art by providing a non-woven filter cotton cutting device.
[0005] The specific technical solution is as follows:
[0006] A nonwoven filter cotton cutting device includes: a cutting table, a feeding roller at one end of the cutting table, two connecting plates fixedly installed at the other end of the cutting table, and a rotating shaft rotatably installed on one side of each of the two connecting plates. A first rotating roller and a second rotating roller are rotatably connected to one end of each of the two rotating shafts. A fixing frame is fixedly installed on the upper surface of the cutting table, and a hydraulic cylinder is provided at one end of the upper surface of the inner wall of the fixing frame. The extension end of the hydraulic cylinder is connected to a nonwoven filter cotton cutting assembly.
[0007] In a preferred embodiment of this utility model, the other ends of the first rotating roller and the second rotating roller respectively pass through the connecting plate on the other side, and a motor is provided on one side of the connecting plate. A first gear and a second gear are installed on the outer surface of the insertion end of the first rotating roller and the second rotating roller. The first gear and the second gear are meshed and connected. The output shaft of the motor is connected to one side of the insertion end of the second rotating roller. The first rotating roller is located above the second rotating roller. A feeding slant box is provided between the cutting table and the first rotating roller, and a slope is provided inside the feeding slant box.
[0008] As a preferred embodiment of the present invention, the nonwoven filter cotton cutting assembly includes a blade mounting frame, which is located at the upper end of the cutting table, and the extension end of the hydraulic cylinder is connected to one end of the upper surface of the blade mounting frame.
[0009] As a preferred embodiment of this utility model, guide rods are fixedly connected to both ends of the upper surface of the tool mounting frame, and the other end of the guide rod passes through one end of the fixed frame surface.
[0010] As a preferred embodiment of this utility model, one end of the upper surface of the inner wall of the tool mounting frame is provided with a mounting groove, a mounting plate is inserted into the mounting groove, a circular cylinder is fixedly mounted on the lower surface of the mounting plate, one end of the tool mounting frame and the mounting plate are respectively provided with threaded holes, and the threaded hole at one end of the tool mounting frame extends through into the mounting groove, a circular cylinder is fixedly mounted on one end of the lower surface of the mounting plate, a positioning bolt is threaded into the threaded hole, a circular ring cutter is provided on the outer edge of the lower surface of the circular cylinder, and a wavy circular cutter is provided on the inner edge of the lower surface of the circular cylinder.
[0011] As a preferred embodiment of this utility model, a groove is provided at the center of the upper surface of the inner wall of the cylindrical tube, a damper is installed on the upper surface of the inner wall of the groove, a spring is connected to the lower surface of the damper, a positioning rod is connected to the other end of the spring, and a rubber head is installed on the lower surface of the positioning rod.
[0012] This utility model has the following beneficial effects:
[0013] 1. The nonwoven filter cotton cutting device provided by this utility model, through the design of a first rotating roller, a second rotating roller, and a nonwoven filter cotton cutting component, pre-wraps the nonwoven filter cotton on the feeding roller to facilitate the normal supply of cutting material. Then, the first and second rotating rollers at the other end of the cutting table pull the filter cotton to be cut. The hydraulic cylinder drives the nonwoven filter cotton cutting component to descend and align for cutting, adapting it to the shape of the capsule filter, thus improving cutting efficiency. The motor drives the second rotating roller to rotate, causing the first gear installed on the periphery of the first rotating roller to drive the second gear installed on the periphery of the second rotating roller to rotate together, pulling and conveying the cut filter cotton to one end. Since the cut filter cotton adapted to the shape of the capsule filter is still together with the whole filter cotton, it can fall into the feeding inclined box between the cutting table and the first rotating roller during the pulling process, thus improving collection efficiency.
[0014] 2. The non-woven filter cotton cutting device provided by this utility model, through the design of a blade frame, a circular blade, a wavy ring blade, and a rubber head, allows the filter cotton to be lowered by a hydraulic cylinder when it is moved to the lower end of the blade frame. During the descent, the guide rod installed on the upper surface of the blade frame can improve its downward cutting stability. Then, the rubber head contacts the filter cotton in the area to be cut beforehand. After the spring is compressed, it rebounds, fixing the cutting area with the rubber head so that the cut filter cotton can be collected later. Then, the circular blade cuts the circular shape to fit the capsule filter, and the wavy ring blade cuts the wavy edge or guide groove inside. The composite cutting is completed in a single punch, ensuring that the cutting edge is flat and the shape meets the usage requirements, improving the cutting quality. The finished product is separated from the raw material, but is still temporarily fixed by the rubber head. After the cutting is completed, the hydraulic cylinder drives the lifting and lowering. Then, when the first and second rotating rollers pull the filter cotton, the finished filter cotton falls into the lower feeding slant box by gravity. The remaining waste material is removed by the first and second rotating rollers. Attached Figure Description

[0028] Example 1
[0029] The nonwoven filter cotton cutting device provided in this embodiment, such as Figures 1-4As shown, it includes: a cutting table 1, a feeding roller 101 at one end of the cutting table 1, and two connecting plates 201 fixedly installed at the other end of the cutting table 1. A rotating shaft 202 is rotatably installed on one side of one of the two connecting plates 201. A first rotating roller 2 and a second rotating roller 203 are rotatably connected to one end of each of the two rotating shafts 202. A fixing frame 3 is fixedly installed on the upper surface of the cutting table 1. A hydraulic cylinder 302 is provided at one end of the upper surface of the inner wall of the fixing frame 3. The extension end of the hydraulic cylinder 302 is connected to a non-woven filter cotton cutting assembly 4. The other ends of the first rotating roller 2 and the second rotating roller 203 respectively pass through the connecting plate 201 on the other side, and a motor 204 is provided on one side of the connecting plate 201. A first gear 205 and a second gear 206 are installed on the outer surface of the insertion end of the first rotating roller 2 and the second rotating roller 203. The first gear 205 and the second gear 206 are meshed and connected. The output shaft of the motor 204 is connected to one side of the insertion end of the second rotating roller 203. The first rotating roller 2 is located above the second rotating roller 203. A feeding slant box 102 is provided between the cutting table 1 and the first rotating roller 2, and a slope is provided inside the feeding slant box 102.
[0030] Through the design of the first rotating roller 2, the second rotating roller 203, and the nonwoven filter cotton cutting assembly 4, the nonwoven filter cotton is first wound around the feeding roller 101 to facilitate the normal supply of cutting material. Then, the first rotating roller 2 and the second rotating roller 203 at the other end of the cutting table 1 pull the filter cotton to be cut. The hydraulic cylinder 302 drives the nonwoven filter cotton cutting assembly 4 to descend and align for cutting, adapting it to the shape of the capsule filter, thus improving cutting efficiency. The motor 204 drives the second rotating roller 203 to rotate, causing the first gear 205 installed on the periphery of the first rotating roller 2 to drive the second gear 206 installed on the periphery of the second rotating roller 203 to rotate together, pulling and conveying the cut filter cotton to one end. Since the cut filter cotton adapted to the shape of the capsule filter is still together with the whole filter cotton, it can fall into the feeding inclined box 102 between the cutting table 1 and the first rotating roller 2 during the pulling process, thus improving collection efficiency.
[0031] Example 2
[0032] The nonwoven filter cotton cutting device provided in this embodiment, such as Figures 3-4As shown, the non-woven filter cotton cutting assembly 4 includes a blade mounting frame 401, which is located at the upper end of the cutting table 1. The extension end of the hydraulic cylinder 302 is connected to one end of the upper surface of the blade mounting frame 401. Guide rods 301 are fixedly connected to both ends of the upper surface of the blade mounting frame 401, and the other end of the guide rods 301 passes through one end of the surface of the fixed frame 3. A mounting groove 402 is provided at one end of the upper surface of the inner wall of the tool holder 401. A mounting plate 405 is inserted into the mounting groove 402. A cylindrical cylinder 404 is fixedly installed on the lower surface of the mounting plate 405. Threaded holes are provided at one end of both the tool holder 401 and the mounting plate 405, with the threaded hole at one end of the tool holder 401 extending into the mounting groove 402. A positioning bolt 403 is threaded into the threaded hole at one end of the lower surface of the mounting plate 405. A circular ring cutter 406 is provided on the outer edge of the lower surface of the cylindrical cylinder 404, and a wavy circular cutter 407 is provided on the inner edge of the lower surface of the cylindrical cylinder 404. A groove is provided at the center of the upper surface of the inner wall of the cylindrical cylinder 404. A damper 408 is installed on the upper surface of the inner wall of the groove. A spring 409 is connected to the lower surface of the damper 408. A positioning rod 410 is connected to the other end of the spring 409, and a rubber head 411 is installed on the lower surface of the positioning rod 410.
[0033] Through the design of the blade mounting frame 401, the circular blade 406, the wavy circular blade 407, and the rubber head 411, when the filter cotton is moved to the lower end of the blade mounting frame 401, it is driven to descend by the hydraulic cylinder 302. During the descent, the guide rod 301 installed on the upper surface of the blade mounting frame 401 can improve its downward cutting stability. Then, the rubber head 411 contacts the filter cotton in the area to be cut, and the spring 409 is compressed and then rebounds, fixing the rubber head 411 in the cutting area so that the cut filter cotton can be collected later. Then, the circular blade 406 cuts the adapter bag. The filter has a circular shape, and the wavy ring cutter 407 cuts the wavy edge or guide groove inside. The composite cutting is completed in a single stamping, which ensures that the cut edge is flat and the shape meets the usage requirements, thus improving the cutting quality. The finished product has been separated from the raw material, but is still temporarily fixed by the rubber head 411. After the cutting is completed, the hydraulic cylinder 302 drives the lifting. Then, when the first rotating roller 2 and the second rotating roller 203 pull the filter cotton, the finished filter cotton falls into the lower feeding inclined box 102 by gravity. The remaining waste material is removed by the first rotating roller 2 and the second rotating roller 203.
[0034] In summary, the nonwoven filter cotton cutting device provided in this embodiment has the following advantages: during cutting, the circular cutter 406 and the wavy circular cutter 407 cut simultaneously, forming the outer circle and functional structure in one step, solving the efficiency problem of step-by-step cutting, and facilitating the collection of finished products and waste materials, avoiding mixing, and improving the ease of recycling.
[0035] In use, when cutting non-woven filter cotton, it is first wound around the feeding roller 101 to facilitate the normal supply of material for cutting. Then, the filter cotton to be cut is pulled by the first rotating roller 2 and the second rotating roller 203 at the other end of the cutting table 1. The hydraulic cylinder 302 drives the blade frame 401 to descend. During the descent, the guide rod 301 installed on the upper surface of the blade frame 401 can improve its downward cutting stability. Then, the rubber head 411 contacts the filter cotton in the area to be cut. After the spring 409 is compressed, it rebounds, fixing the rubber head 411 in the cutting area so that the cut filter cotton can be collected later. After collection, the circular shape of the filter is cut by the circular cutter 406 to fit the bladder filter. The wavy ring cutter 407 cuts the wavy edge or guide groove inside. The composite cutting is completed in a single stamping, ensuring that the cut edge is flat and the shape meets the usage requirements, thus improving the cutting quality. The finished product has been separated from the raw material, but is still temporarily fixed by the rubber head 411. After the cutting is completed, the hydraulic cylinder 302 drives the lifting. Then, when the first rotating roller 2 and the second rotating roller 203 pull the filter cotton, the finished filter cotton falls into the lower feeding inclined box 102 by gravity. The remaining waste material is removed by the first rotating roller 2 and the second rotating roller 203.
[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
