Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, specifically to an adjustable cutting mechanism for a nonwoven fabric slitting machine. Background Technology

[0002] The main function of a nonwoven fabric slitting machine is to cut wide rolls of material into various narrow rolls suitable for production needs. Specifically, during the production process, the nonwoven fabric slitting machine performs operations such as edge trimming and slitting on wide materials according to different requirements.

[0003] Application No. CN201821593489.8 discloses a nonwoven fabric slitting machine, including a slitting frame. Bending rods are fixedly connected to both sides of the slitting frame. A cylinder is fixedly connected to the upper end of each bending rod, and a push block is fixedly connected to the output end of the cylinder. A limiting mechanism corresponding to the push block is connected between the slitting frame and the bending rods. A crossbar is fixedly connected to the push block, and a disc is rotatably connected to the end of the crossbar away from the push block. A locking mechanism corresponding to the disc is provided on the push block. A slitting roller contacts the two discs, and multiple cutting rings are provided on the slitting roller. The cutting rings are connected to the slitting roller through a fastening mechanism. This utility model has a compact structure and is easy to operate. The distance between the two cutting blades can be adjusted according to the required slitting width, improving the overall applicability of the slitting machine. Furthermore, the distance between the cutting blades and the cutting roller can be adjusted to prevent loosening during nonwoven fabric cutting, thus avoiding affecting the cutting accuracy.

[0004] Although the distance between the two cutting blades can be adjusted according to the required slitting width in the aforementioned document, the adjustment requires manual adjustment and measurement with a ruler. This method of measuring each blade with a ruler wastes a lot of time and reduces work efficiency. To address the above problems, the inventor proposed an adjustable cutting blade mechanism for a nonwoven fabric slitting machine. Utility Model Content

[0005] In order to solve the problem of low efficiency when adjusting the cutting mechanism, the purpose of this utility model is to provide an adjustable cutting mechanism for a nonwoven fabric slitting machine.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: an adjustable cutting mechanism for a nonwoven fabric slitting machine, comprising a slitting machine body and a cutting mechanism body, wherein the slitting machine body includes a base plate, the cutting mechanism body is located above the base plate, an unwinding mechanism and a winding mechanism are respectively installed on both sides of the top surface of the base plate, a fixed plate is fixedly provided on the top surface of the base plate, a first limiting roller is rotatably connected between the fixed plates, a first support plate is fixedly provided on the top surface of the fixed plate, a second limiting roller is rotatably connected between the first support plates, a second support plate is fixedly provided on the top surface of the base plate, and a third limiting roller is rotatably connected between the second support plates;

[0007] The cutting mechanism body includes a mounting frame, an L-shaped plate fixedly installed inside the mounting frame, a second motor installed inside the L-shaped plate, a lead screw fixedly installed at the output end of the second motor, a cutting body slidably installed inside the mounting frame, and multiple sets of cutting bodies, one set of which has a threaded tube fixedly installed inside the cutting body, the lead screw thread passing through the outer surface of the threaded tube, a second guide rod rotatably installed on the top surface of each set of cutting bodies, and the second guide rods are hinged to each other, a first guide rod is hinged on the top surface of the L-shaped plate, one of the second guide rods is hinged to the first guide rod, a sliding rod is fixedly installed inside the mounting frame, and fixing ears are fixedly installed on both sides of each set of cutting bodies, the fixing ears slidingly sleeved on the outer surface of the sliding rod. First, the non-woven fabric roll to be slit is installed in the unwinding mechanism, then one end is manually pulled up and passed through the bottom end of the first limiting roller, then through the top end of the second limiting roller, and then through the bearing roller and the cutting body in the support frame, then through the bottom end of the third limiting roller, and then fixed in the winding mechanism;

[0008] Next, by turning on the second motor, the lead screw is rotated, which causes the threaded tube inside the cutter body away from the second motor to be threaded onto the outer surface of the lead screw and move away from the second motor. At the same time, the second guide rods set on the top surface of each cutter body can be hinged to each other and rotate. Thus, when the cutter body away from the second motor moves, each cutter body moves, and the distance moved between each cutter body is the same. Therefore, it is not necessary to measure the distance between every two cutter bodies during adjustment.

[0009] Then, manually slide the moving lever so that the pointer and scale line work together to adjust the distance between the cutter body on one side of the slide plate and the baffle, making it the same as the distance between the two adjacent cutter bodies. Then, turn on the first motor, so that the threaded rod rotates inside the horizontal plate and the threaded block drives the mounting frame to slide, so that the baffle can fit against one side of the nonwoven fabric. Then, the cutter body can cut the nonwoven fabric to the required width of slits. By turning on the cylinder, the horizontal plate mounting frame moves downward and inserts into the nonwoven fabric. Then, the nonwoven fabric is automatically cut into slits during unwinding and rewinding.

[0010] Preferably, a sliding plate is fixedly provided on one side of one of the sets of cutter bodies, a moving rod is slidably provided in the sliding plate, a baffle is fixedly provided on the bottom surface of the moving rod, a fixing ring is fixedly provided on the top end of the moving rod, a pointer is fixedly provided on the outer surface of the fixing ring, a scale line is fixedly provided on the top surface of the sliding plate, a groove is provided in the sliding plate, and a sliding ring is fixedly fitted on the outer surface of the moving rod, and the sliding ring is slidably provided in the groove.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figure 1-7As shown, this utility model provides an adjustable cutting mechanism for a nonwoven fabric slitting machine, including a slitting machine body 1 and a cutting mechanism body 4. The slitting machine body 1 includes a base plate 11, and the cutting mechanism body 4 is located above the base plate 11. An unwinding mechanism 2 and a winding mechanism 21 are respectively installed on both sides of the top surface of the base plate 11. A fixing plate 12 is fixedly provided on the top surface of the base plate 11, and a first limiting roller 13 is rotatably connected between the fixing plates 12. A first support plate 14 is fixedly provided on the top surface of the fixing plates 12, and a second limiting roller 15 is rotatably connected between the first support plates 14. A second support roller 15 is fixedly provided on the top surface of the base plate 11. A third limiting roller 17 is rotatably connected between plate 16 and the second support plate 16. The non-woven fabric roll to be slit is installed in the unwinding mechanism 2, and then one end is manually pulled up and passed through the bottom end of the first limiting roller 13, then through the top end of the second limiting roller 15, and then through the bearing roller and cutter body 46 in the support frame 3, and then through the bottom end of the third limiting roller 17, and then fixed in the winding mechanism 21. (Both the unwinding mechanism 2 and the winding mechanism 21 are composed of a drive motor, a rotating shaft, a detachable frame, and an unwinding roller. When started, they cause the non-woven fabric to be wound and unwound.)

[0026] The cutting mechanism body 4 includes a mounting frame 401. An L-shaped plate 44 is fixedly installed inside the mounting frame 401. A second motor 41 is installed inside the L-shaped plate 44. A lead screw 42 is fixedly installed at the output end of the second motor 41. A cutting body 46 is slidably installed inside the mounting frame 401. There are multiple sets of cutting bodies 46. A threaded tube 461 is fixedly installed inside one set of cutting bodies 46. The lead screw 42 is threaded through the outer surface of the threaded tube 461. A second guide rod 48 is rotatably installed on the top surface of each set of cutting bodies 46, and the second guide rods 48 are hinged to each other. A first guide rod 45 is hinged to the top surface of the L-shaped plate 44. One of the second guide rods 48 is hinged to the first guide rod 45. A sliding rod 43 is fixedly installed inside the mounting frame 401. The two sides of the multiple sets of cutting bodies 46 are connected to each other. Each side is fixed with a fixing ear 47, which is slidably sleeved on the outer surface of the slide rod 43. By turning on the second motor 41, the lead screw 42 is rotated, which causes the threaded tube 461 in the cutter body 46 away from the second motor 41 to be threaded onto the outer surface of the lead screw 42 and move away from the second motor 41. At the same time, the second guide rod 48 provided on the top surface of each cutter body 46 can be hinged and rotated with each other. Thus, when the cutter body 46 on the side away from the second motor 41 moves, it drives each cutter body 46 to move, and the distance moved between each cutter body 46 is the same. Therefore, the distance between every two cutter bodies 46 does not need to be measured during adjustment, which reduces a lot of time and improves the efficiency of nonwoven fabric slitting.

[0027] A sliding plate 5 is fixedly mounted on one side of one of the cutter bodies 46. A moving rod 52 is slidably mounted inside the sliding plate 5. A baffle 56 is fixedly mounted on the bottom surface of the moving rod 52. A fixing ring 54 is fixedly mounted on the top of the moving rod 52. A pointer 55 is fixedly mounted on the outer surface of the fixing ring 54. A scale line 51 is fixedly mounted on the top surface of the sliding plate 5. A groove 501 is opened inside the sliding plate 5. A sliding ring 53 is fixedly mounted on the outer surface of the moving rod 52. The sliding ring 53 is slidably mounted in the groove 501. A threaded block 35 is fixedly mounted on the top surface of the mounting bracket 401. The threaded block 35 is slidably mounted inside the horizontal plate 32. A first motor 33 is mounted on one side of the horizontal plate 32. A threaded rod 34 is fixedly mounted on the output end of the first motor 33. The threaded block 35 is threadedly mounted on the outer surface of the threaded rod 34.

[0028] By adopting the above technical solution, after the distance between the cutter bodies 46 is adjusted, the distance between the cutter body 46 and the baffle 56 on one side of the slide plate 5 can be adjusted by manually sliding the moving rod 52 so that the pointer 55 and the scale line 51 cooperate with each other and become the same as the distance between the two adjacent cutter bodies 46. Then, the first motor 33 is turned on, so that the threaded rod 34 rotates in the horizontal plate 32 and the threaded block 35 drives the mounting bracket 401 to slide, so that the baffle 56 can fit against one side of the non-woven fabric, and then the cutter body 46 can cut the non-woven fabric to the required width of slitting.

[0029] A support frame 3 is fixedly provided on the top surface of the base plate 11. A cylinder 31 is installed on the top surface of the support frame 3. A horizontal plate 32 is fixedly provided at the output end of the cylinder 31. The mounting bracket 401 slides on the bottom surface of the horizontal plate 32.

[0030] By adopting the above technical solution, the cylinder 31 is opened, thereby causing the horizontal plate 32 mounting bracket 401 to move downward and insert into the non-woven fabric, so that the non-woven fabric is automatically cut into strips during unwinding and rewinding.

[0031] Working principle: First, the non-woven fabric roll that needs to be slit is installed in the unwinding mechanism 2. Then, one end is manually pulled up and passed through the bottom end of the first limiting roller 13, then through the top end of the second limiting roller 15, and then through the space between the bearing roller and the cutter body 46 in the support frame 3. Finally, it passes through the bottom end of the third limiting roller 17 and is then fixed in the winding mechanism 21.

[0032] Next, by turning on the second motor 41, the lead screw 42 is rotated, which causes the threaded tube 461 inside the cutter body 46 away from the second motor 41 to be threaded onto the outer surface of the lead screw 42 and move away from the second motor 41. At the same time, the second guide rods 48 provided on the top surface of each cutter body 46 can be hinged to each other and rotate. Thus, when the cutter body 46 on the side away from the second motor 41 moves, each cutter body 46 moves, and the distance that each cutter body 46 moves is the same. Therefore, it is not necessary to measure the distance between every two cutter bodies 46 during adjustment.

[0033] Then, manually slide the moving rod 52 so that the pointer 55 and the scale line 51 cooperate with each other, causing the distance between the cutter body 46 on one side of the slide plate 5 and the baffle 56 to be adjustable and the same as the distance between two adjacent cutter bodies 46. Then, turn on the first motor 33, so that the threaded rod 34 rotates in the horizontal plate 32 and causes the threaded block 35 to drive the mounting frame 401 to slide, so that the baffle 56 can fit against one side of the nonwoven fabric. Then, the cutter body 46 can cut the nonwoven fabric to the required width of slitting. By turning on the cylinder 31, the mounting frame 401 of the horizontal plate 32 moves downward and inserts into the nonwoven fabric. Then, the nonwoven fabric is automatically cut into slitting during unwinding and rewinding.

[0034] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
