Description
Technical Field
[0001] This utility model relates to the technical field of nonwoven fabric processing equipment, and specifically discloses a cutting device for nonwoven fabric processing. Background Technology
[0002] Nonwoven fabric, also known as non-woven cloth, is a fibrous product formed by directly bonding fibers through physical or chemical methods. It has properties such as breathability, moisture resistance, and biodegradability. Its raw materials are mainly polypropylene, polyester, and viscose fiber. It is used in medical and health, daily necessities, industrial agriculture, and environmental protection fields. In the production process of nonwoven fabric, cutting equipment is usually used to cut the nonwoven fabric into the required size for further processing and use.
[0003] Chinese patent CN221589047U discloses a nonwoven fabric fixed-length cutting device, which relates to the field of cutting device technology. It includes an operating table, a square plate is provided above the operating table, a sliding channel is opened inside the square plate, and a slide seat is slidably provided at both ends of the sliding channel. A cylinder is fixedly connected to the bottom of the slide seat, a slide rod is slidably connected to the bottom of the cylinder, and a U-shaped frame is fixedly connected to the bottom of the slide rod. This nonwoven fabric fixed-length cutting device controls the extension end of the first electric push rod to extend, causing the slide rod to drive the U-shaped frame to slide downwards, and the pressure roller to adhere to the nonwoven fabric. Then, the motor is started, and the motor rotation drives the threaded rod to rotate, causing the two slide blocks to move in opposite directions, and then the pressure roller to roll on the nonwoven fabric, smoothing the nonwoven fabric. Then, the extension end of the first electric push rod is controlled to continue to extend, and the pressure roller presses down on the nonwoven fabric, positioning the nonwoven fabric from both sides of the cutting part to ensure the stability of the nonwoven fabric during the cutting process. However, the above device cannot restrict the position of nonwoven fabrics of different widths during use, which can easily cause the nonwoven fabric to be misaligned and shifted during the movement of the nonwoven fabric towards the limiting strip, affecting the cutting quality and wasting nonwoven fabric. In addition, debris and dust on the nonwoven fabric can easily fall into the second slide groove, affecting the movement of the second slider below the limiting strip, which is quite inconvenient. Therefore, in order to solve the above problems, this utility model proposes a cutting device for nonwoven fabric processing. Utility Model Content
[0004] The present invention aims to provide a cutting device for nonwoven fabric processing, which can restrict the position of the nonwoven fabric from both sides, prevent the nonwoven fabric from shifting during movement, ensure the quality of nonwoven fabric cutting, reduce nonwoven fabric waste, prevent debris or dust from blocking the second limiting hole, and ensure the smooth movement of the abutment plate and clamping block.
[0005] This utility model is achieved through the following technical solution:
[0006] A cutting device for nonwoven fabric processing includes a worktable and a controller. The controller is located on one side of the worktable, and scale plates are located on both sides of the worktable. A cutting mechanism is located above the worktable, and a limiting mechanism is located on one side of the cutting mechanism. The cutting mechanism includes a support, and a cutter is located on the inner side of the support. A first electric telescopic rod is connected to the upper center of the cutter, and a protective plate is located below the cutter. A second electric telescopic rod is connected to the middle of one side of the protective plate. A pressure roller is located on the side of the support away from the limiting mechanism, and a support base is rotatably connected to both ends of the pressure roller. The limiting mechanism includes two side plates, and a lead screw is rotatably connected to the middle of the side plates that are far apart from each other. A stop plate is located on the side plate away from the support, and clamping blocks are located at both ends of the stop plate.
[0007] As a further feature of the above solution, two first guide rods are symmetrically connected above the cutter. Both first guide rods pass through the top of the bracket and are slidably connected to the bracket, which can further restrict the movement direction of the cutter. Two second guide rods are symmetrically connected on the side of the protective plate near the second electric telescopic rod. Both second guide rods pass through the side of the bracket and are slidably connected to the bracket, which can further restrict the movement direction of the protective plate, reduce the downward pulling force exerted by the protective plate on the telescopic end of the second electric telescopic rod, and extend the service life of the second electric telescopic rod.
[0008] As a further feature of the above solution, a third guide rod is connected to the lower center of each of the two support seats. A spring is sleeved on the outer side of the third guide rod, and the upper end of the spring is connected to the support seat. This allows the pressure roller to squeeze the non-woven fabric and the worktable under the action of gravity. When the user pulls the non-woven fabric, an upward pulling force is applied to the non-woven fabric, causing the pressure roller to move upward and stretch the spring, thereby smoothly pulling the non-woven fabric from under the pressure roller. The lower end of the spring is connected to a connecting plate, and the third guide rod passes through the interior of the connecting plate and is slidably connected to the connecting plate, which can limit the position of the spring and the support seat. The connecting plate is connected to the worktable, making it convenient to disassemble and assemble the connecting plate and its connecting components.
[0009] As a further feature of the above solution, the workbench has a cutter hole inside that corresponds to the position of the cutter, ensuring that the cutter cuts through the non-woven fabric and avoiding conflict between the cutter and the workbench. A first limiting hole is provided on one side of the cutter hole, and a first sliding rod is provided in the lower center of the side plate. The first sliding rod passes through the interior of the first limiting hole and is slidably connected to the first limiting hole, which can restrict the movement direction of the side plate. A first limiting ring is detachably connected to the outside of the first sliding rod to prevent the first sliding rod from being pulled out of the first limiting hole. A mounting seat is threaded to the outside of the lead screw to provide support for the lead screw and facilitate the movement of the side plate during the rotation of the lead screw.
[0010] As a further feature of the above scheme, a second limiting hole is provided on one side of each of the two scale plates, and a second sliding rod is provided at both ends of the lower part of the abutment. The second sliding rod passes through the interior of the second limiting hole and is slidably connected to the second limiting hole, which can restrict the movement direction of the abutment. A second limiting ring is detachably connected to the outside of the second sliding rod, which can prevent the second sliding rod from separating from the second limiting rod during movement.
[0011] As a further feature of the above solution, a clamping groove is provided on one side of the clamping block, and the two side walls of the clamping groove are in contact with the two sides of the second sliding rod, which can restrict the position of the abutment and the second sliding rod after the abutment stops moving, so that the abutment remains upright.
[0012] The clamping block in this invention is made of elastic materials such as silicone and latex. The first and second electric telescopic rods are both connected to the controller via power lines and signal lines. The driving devices for both electric telescopic rods are known and conventional in the art, and therefore are not shown in the accompanying drawings. The zero mark of the scale plate is aligned with the blade of the cutter.
[0013] The present invention has the following beneficial effects during use:
[0014] The combination of the protective plate and the second electric telescopic rod in the cutting mechanism can push the protective plate under the cutter after the cutter has finished cutting, preventing the user from touching the cutter while reaching under it to pull the non-woven fabric, thus ensuring the user's safety.
[0015] The combination of pressure roller, support base, spring and third guide rod allows the nonwoven fabric to be squeezed against the worktable by the weight of the pressure roller itself during the nonwoven fabric cutting process. This fixes the nonwoven fabric located on the side away from the cutter plate. When the user pulls the nonwoven fabric, an upward pulling force is applied to the nonwoven fabric, which drives the pressure roller to move upward and stretch the spring, thus smoothly pulling the nonwoven fabric from below the pressure roller to the side of the cutter plate.
[0016] The combination of the two side plates and the lead screw in the limiting mechanism can restrict the position of the nonwoven fabric from both sides, preventing the nonwoven fabric from shifting during the pulling process. The combination of the abutment plate and the two clamping blocks can fix the abutment plate after the position of the abutment plate is adjusted, keeping the abutment plate in a vertical state. The use of the first limiting hole and the second limiting hole can prevent debris from accumulating in the two limiting holes, making it convenient for users to clean the two limiting holes.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-9 This application will be described in detail with reference to the embodiments.
[0030] An embodiment discloses a cutting device for nonwoven fabric processing, including a workbench 1 and a controller 2. The controller 2 is provided on one side of the workbench 1, and scale plates 14 are provided on both sides of the workbench 1. A cutting mechanism 3 is provided above the workbench 1, and a limiting mechanism 4 is provided on one side of the cutting mechanism 3. The cutting mechanism 3 includes a bracket 31, and a cutter 32 is provided on the inner side of the bracket 31. A first electric telescopic rod 33 is connected to the upper center of the cutter 32, and a protective plate 34 is provided below the cutter 32. A second electric telescopic rod 35 is connected to the middle of one side of the protective plate 34. A pressure roller 36 is provided on the side of the bracket 31 away from the limiting mechanism 4. Both ends of the pressure roller 36 are rotatably connected to support seats 37. The limiting mechanism 4 includes two side plates 41, and a lead screw 42 is rotatably connected to the middle of the side of the two side plates 41 away from each other. A stop plate 44 is provided on the side of the side plate 41 away from the bracket 31, and clamping blocks 45 are provided at both ends of the stop plate 44.
[0031] like Figure 1 , Figure 3 and Figure 4 As shown, two first guide rods 321 are symmetrically connected above the cutter 32. Both first guide rods 321 pass through the top of the bracket 31 and are slidably connected to the bracket 31, which can further restrict the movement direction of the cutter 32. Two second guide rods 341 are symmetrically connected on the side of the protective plate 34 near the second electric telescopic rod 35. Both second guide rods 341 pass through the side of the bracket 31 and are slidably connected to the bracket 31, which can further restrict the movement direction of the protective plate 34, reduce the downward pulling force exerted by the protective plate 34 on the telescopic end of the second electric telescopic rod 35, and extend the service life of the second electric telescopic rod 35.
[0032] like Figure 1 and Figure 5As shown, a third guide rod 371 is connected to the lower center of each of the two support seats 37. A spring 38 is sleeved on the outer side of the third guide rod 371. The upper end of the spring 38 is connected to the support seat 37, which allows the pressure roller 36 to squeeze the non-woven fabric and the worktable 1 under the action of gravity. When the user pulls the non-woven fabric, an upward pulling force is applied to the non-woven fabric, which drives the pressure roller 36 to move upward and stretch the spring 38, thereby smoothly pulling the non-woven fabric from under the pressure roller 36. The lower end of the spring 38 is connected to a connecting plate 39. The third guide rod 371 passes through the interior of the connecting plate 39 and is slidably connected to the connecting plate 39, which can limit the position of the spring 38 and the support seat 37. The connecting plate 39 is connected to the worktable 1, which facilitates the disassembly and assembly of the connecting plate 39 and its connecting parts.
[0033] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the workbench 1 has a cutter hole 11 inside that corresponds to the position of the cutter 32, which ensures that the cutter 32 can cut through the non-woven fabric and avoids conflict between the cutter 32 and the workbench 1. A first limiting hole 12 is provided on one side of the cutter hole 11. A first sliding rod 411 is provided in the lower center of the side plate 41. The first sliding rod 411 passes through the inside of the first limiting hole 12 and is slidably connected to the first limiting hole 12, which can limit the movement direction of the side plate 41. A first limiting ring 412 is detachably connected to the outside of the first sliding rod 411, which can prevent the first sliding rod 411 from being pulled out of the first limiting hole 12. A mounting base 43 is threadedly connected to the outside of the lead screw 42, which can provide support for the lead screw 42 and facilitate the movement of the side plate 41 during the rotation of the lead screw 42.
[0034] like Figure 1 , Figure 2 and Figure 8 As shown, each of the two scale plates 14 has a second limiting hole 13 on one side, and each of the two lower ends of the abutment plate 44 has a second sliding rod 441. The second sliding rod 441 passes through the interior of the second limiting hole 13 and is slidably connected to the second limiting hole 13, which can restrict the movement direction of the abutment plate 44. A second limiting ring 442 is detachably connected to the outside of the second sliding rod 441, which can prevent the second sliding rod 441 from separating from the second limiting rod during movement.
[0035] like Figure 1 and Figure 9 As shown, a clamping groove 451 is provided on one side of the clamping block 45. Both sides of the clamping groove 451 are in contact with the sides of the second sliding rod 441, which can restrict the position of the abutment 44 and the second sliding rod 441 after the abutment 44 stops moving, so that the abutment 44 remains upright.
[0036] The nonwoven fabric cutting device disclosed in this embodiment, before use, adjusts the abutment plate 44 to a suitable position according to the cutting requirements of the nonwoven fabric and with reference to the scale on the scale plate 14, so that the second slide rod 441 slides in the second limiting hole 13. After adjustment, the two clamping blocks 45 are respectively inserted into the two second limiting holes 13, so that the clamping grooves 451 squeeze the second slide rod 441 from both sides, clamping the second slide rod 441, and the second limiting hole 13 squeezes the clamping blocks 45, so that the elastic clamping blocks 45 reversibly generate... The deformation, through the friction of the clamping block 45 and the second limiting hole 13, restricts the position of the clamping block 45 and the abutment plate 44. After the non-woven fabric to be cut passes under the pressure roller 36, it is pulled to one side of the abutment plate 44, so that one end of the non-woven fabric abuts against the side of the abutment plate 44 near the support 31. The two screws 42 are rotated in sequence, causing the first sliding rod 411 under the side plate 41 to slide in the first limiting hole 12. The position of the side plate 41 is adjusted so that the two side plates 41 move closer to the two sides of the non-woven fabric. When the side plate 41 is about to contact the non-woven fabric, the screws 42 are stopped from rotating.
[0037] Tools of a certain weight, such as scissors and rulers, are placed on the non-woven fabric on one side of the backing plate 44. In conjunction with the pressure roller 36, the non-woven fabric is pressed tightly from both sides of the cutter 32. The controller 2 controls the second electric telescopic rod 35 to retract, removing the protective plate 34 from under the cutter 32. The controller 2 then controls the first electric telescopic rod 33 to extend, pushing the cutter 32 towards the non-woven fabric to cut it. After cutting, the first electric telescopic rod 33 is retracted, resetting the cutter 32. The second electric telescopic rod 35 is extended, pushing the protective plate 34 under the cutter 32. The tools are removed from the non-woven fabric, and the non-woven fabric is removed from the worktable 1. The non-woven fabric end located to the left of the cutter 32 is pulled to release the non-woven fabric. An upward pulling force is applied to the head, causing the pressure roller 36 to move upward a certain distance, stretching the spring 38 so that the non-woven fabric can be smoothly pulled from below the pressure roller 36 to one side of the backing plate 44. When the non-woven fabric stops being pulled, the pressure roller 36 squeezes the non-woven fabric and the worktable 1 by its own weight, thereby fixing the non-woven fabric on the side of the cutter 32 away from the backing plate 44. The tool is then placed on the non-woven fabric on the side of the backing plate 44 again, and the controller 2 is used to control the extension and retraction of the first electric telescopic rod 33 and the second electric telescopic rod 35 to cut the non-woven fabric. After a period of time, the debris or dust attached to the first limiting hole 12, the two lead screws 42 and the second limiting hole 13 are cleaned to ensure that the lead screw 42, the first slider and the second slider can be used normally.
[0038] The components of the nonwoven fabric processing cutting device disclosed in this utility model, including the worktable 1, controller 2, scale plate 14, bracket 31, cutter 32, first guide rod 321, first electric telescopic rod 33, protective plate 34, second guide rod 341, second electric telescopic rod 35, pressure roller 36, support seat 37, third guide rod 371, spring 38, side plate 41, lead screw 42, mounting seat 43, abutment plate 44, second slide rod 441, and clamping block 45, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
