Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric production technology, specifically to an automatic nonwoven fabric slitting device and its processing technology. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth, is a type of fabric formed without spinning or weaving. It is made of oriented or randomly arranged fibers bonded together by mechanical, thermal, or chemical methods. Due to its advantages such as short production process, high output, low cost, and excellent performance (e.g., breathability, waterproofing, flexibility, and non-toxicity), it is widely used in many fields, including medical and health care (e.g., masks, protective clothing, disinfectant wipes), home decoration (e.g., wallpaper, tablecloths), agricultural coverings, filter materials, automotive interiors, and packaging materials.

[0003] In the complete production process of nonwoven fabrics, the master rolls produced by processes such as meltblown and spunbond are usually very wide (up to several meters), while downstream end customers require rolls or sheets of specific widths and lengths. Therefore, the slitting process has become an indispensable and crucial link in the post-processing of nonwoven fabrics. The purpose of slitting is to precisely cut the wide master rolls into multiple smaller rolls of uniform width and length according to customer needs through actions such as cutting and rewinding, in order to meet the requirements of subsequent deep processing, packaging, and use.

[0004] Nonwoven fabric slitting equipment is mainly used to roll up and slit wide nonwoven fabric rolls to meet different product specifications and requirements. Such equipment plays a key role in the nonwoven fabric production line and directly affects product quality and production efficiency.

[0005] In the prior art, there is a Chinese patent with the announcement number CN220641974U entitled "A High-Efficiency Slitting Device for Nonwoven Fabric Winding". The patent discloses a high-efficiency slitting device for nonwoven fabric winding, including a slitting machine. A threaded rod is rotatably connected to the right side of the front end of the slitting machine. A first motor is fixedly connected to the middle of the front end of the slitting machine. The left end of the threaded rod is fixedly connected to the drive end of the first motor. A crossbar is threadedly connected to the outer wall of the threaded rod and passes through the left and right sides. The upper and lower ends of the crossbar are slidably connected to the inner wall of the right side of the slitting machine and pass through the rear side. Two sets of first-stage electric push rods are fixedly connected to the top of the crossbar. A lower traction block is fixedly connected to the top of each of the first-stage electric push rods at opposite ends.

[0006] For example, Chinese patent application CN113697578A, entitled "An Automatic Nonwoven Fabric Slitting Device," discloses an automatic nonwoven fabric slitting device comprising: a worktable with a mounting groove in the center; a transmission assembly mounted on both sides of the worktable; a cutting assembly fixedly mounted in the center of the sub-worktable; and a pressing assembly slidably disposed on both sides of the worktable. The pressing assembly includes a moving frame, a telescopic cylinder, a fixed frame, a rotating shaft, a rotating plate, a stop plate, and a pressure plate. Two moving frames slide symmetrically on both sides of the worktable via a sliding assembly. The telescopic cylinder is fixedly mounted on the horizontal end of the upper side of the moving frame. The middle of the horizontal end of the fixed frame is fixedly connected to the driving end of the telescopic cylinder. The rotating shaft is rotatably connected between the fixed frames. The rotating plate is fixedly connected to the rotating shaft. The stop plate is vertically rotatably connected to the bottom end of the rotating plate. Existing technologies, including the aforementioned patent, can improve the cutting efficiency of nonwoven fabrics to a certain extent and meet work requirements.

[0007] However, the following shortcomings still exist: As is well known, after nonwoven fabric is wound up, it is usually cut using a cutting blade. In the existing technology, the machine needs to be stopped for cutting after the nonwoven fabric is wound up. That is, after the winding roller stops rotating, an additional power source is needed to drive the cutting mechanism for cutting. At this time, the power source driving the winding roller is in a stationary state. There is a time difference between the two, resulting in low equipment utilization efficiency and certain shortcomings. Summary of the Invention

[0008] The purpose of this invention is to provide an automatic nonwoven fabric slitting device and its processing technology to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an automatic nonwoven fabric slitting device, comprising a frame and a base mounted on the bottom of the frame, wherein a carrying roller for receiving nonwoven fabric is rotatably connected to the frame, and a take-up roller is also provided on the side of the frame away from the carrying roller, and a motor for driving the take-up roller to rotate is provided on the frame; a cutting component is vertically slidably connected to the frame, and a cutting table is fixedly connected to the frame, the cutting component is connected to the frame through an adjustment mechanism, and the motor drive shaft and the adjustment mechanism are connected by a one-way transmission mechanism; first station: when the motor drive shaft rotates forward, it drives the take-up roller to perform a take-up operation on the nonwoven fabric; second station: when the motor drive shaft rotates in reverse, the one-way transmission mechanism drives the adjustment mechanism to unlock the cutting component, and the cutting component performs a cut operation on the taken-up nonwoven fabric.

[0010] Furthermore, the cutting assembly includes a cutting blade that is vertically slidably connected to the frame, a connecting block that is fixedly connected to the cutting blade, and multiple cutting springs that are provided between the cutting blade and the frame.

[0011] Furthermore, the adjustment mechanism includes a sliding rod slidably connected to the frame, a locking block fixedly connected to the sliding rod, and a locking groove adapted to the locking block on the connecting block, wherein the locking block and the locking groove are engaged; it also includes a rotating rod rotatably connected to the frame, the rotating rod being connected to the sliding rod through a transmission unit.

[0012] Furthermore, an extrusion section is vertically slidably connected to the frame, and the extrusion section is connected to the rotating rod for transmission. During the stroke of the sliding rod driving the locking block to slide out of the locking groove to unlock the cutting knife, the extrusion section moves downward to extrude and fix the non-woven fabric that has been rolled up.

[0013] Furthermore, the extrusion section includes an extrusion plate, an extrusion frame is fixedly connected to the extrusion plate, a second rack is fixedly connected to the extrusion frame, and a second gear is provided on the rotating rod, the second gear meshing with the second rack; an extension block is fixedly connected to the second rack, and a positioning spring is provided between the extension block and the extrusion, the elastic force of the positioning spring driving the extrusion section to retract into the frame.

[0014] Furthermore, the transmission unit includes a first rack, a first gear is mounted on the rotating rod, the first gear meshes with the first rack, and a sliding groove is provided on the first rack. The sliding rod is slidably connected to the first rack through the sliding groove, and a buffer spring is also provided between the sliding rod and the sliding groove.

[0015] Furthermore, the locking block and the frame are provided with a first elastic element, and a second elastic element is also provided between the first rack and the frame.

[0016] Furthermore, a linkage rod is also provided on the rotating rod, the one-way transmission mechanism is provided between the linkage rod and the rotating rod, and a synchronizing element is provided between the linkage rod and the motor drive shaft.

[0017] Furthermore, the one-way transmission component includes a wedge-shaped insert that is slidably connected to the rotating rod, a compression spring is provided between the wedge-shaped insert and the rotating rod, and a slot is provided on the linkage rod, the elastic force of the compression spring driving the wedge-shaped insert to engage in the slot.

[0018] A nonwoven fabric processing technology, including the aforementioned automatic nonwoven fabric slitting device, specifically includes the following steps: S1: Install the non-woven fabric to be cut between the carrying roller and the winding roller, in preparation for the winding and cutting operation; S2: When the motor starts and the motor drive shaft rotates forward, it drives the take-up roller to rotate and take up the non-woven fabric. S3: After the winding operation is completed, the motor stops rotating, and the winding roller stops winding at this time; S4: The motor starts again. At this moment, the motor drive shaft reverses and drives the adjustment mechanism to slide out of the cutting assembly where there is a working time difference between the two through the synchronizing component and the one-way transmission component. S5: After the adjustment mechanism slides out of the cutting assembly, the elastic force of the cutting spring causes the cutting blade to slide downwards and cut the wound non-woven fabric. S6: After slitting, the motor stops rotating again, and the rewinding roller can be removed from the frame.

[0019] Compared with existing technologies, the beneficial effects of this invention are as follows: This automatic nonwoven fabric slitting device and its processing technology, through the cooperation between the frame, support roller, cutting component, motor, and one-way transmission mechanism, uses the forward rotation of the motor to drive the winding and the reverse rotation to drive the cutting component to unlock, eliminating the need to stop the machine to switch processes. This solves the problem in traditional technologies where the machine must be stopped after winding before cutting can begin, significantly improving production efficiency. Simultaneously, the one-way transmission mechanism uses the forward and reverse rotation of the motor for winding and cutting respectively, eliminating the need for a separate drive device for cutting, avoiding the use of an additional power source, and reducing equipment costs and energy consumption. Furthermore, the cutting action is automatically triggered after winding, requiring no manual intervention, enhancing the continuity of equipment operation, reducing idling and waiting time, and significantly improving equipment utilization.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-13This invention provides a technical solution: an automatic nonwoven fabric slitting device, including a frame 1 and a base 2 installed on the bottom of the frame 1. A carrying roller 3 for holding nonwoven fabric 5 is rotatably connected to the frame 1, and a winding roller 4 is also provided on the side of the frame 1 away from the carrying roller 3. A device for driving the winding roller 4 to rotate is provided on the frame 1. A cutting component 7 is vertically slidably connected to the frame 1, and a cutting table 6 is fixedly connected to the frame 1. The cutting component 7 is connected to the frame 1 through an adjustment mechanism 9, and the drive shaft of a motor 8 is connected to the adjustment mechanism 9 through a one-way transmission mechanism 13. First station: when the drive shaft of the motor 8 rotates forward, it drives the winding roller 4 to wind up the nonwoven fabric 5. Second station: when the drive shaft of the motor 8 rotates in reverse, it drives the adjustment mechanism 9 through the one-way transmission mechanism 13 to unlock the cutting component 7, and the cutting component 7 cuts the wound nonwoven fabric 5.

[0025] Specifically, the automatic nonwoven fabric slitting device includes a frame 1 and a base 2 mounted on the bottom of the frame 1. The base 2 has an anti-slip pad on its bottom to improve the stability of the slitting device during operation. A carrying roller 3 for holding the nonwoven fabric 5 is rotatably connected to the frame 1, and a take-up roller 4 is also located on the side of the frame 1 away from the carrying roller 3. A motor 8 is mounted on the frame 1 to drive the take-up roller 4 to rotate, and the take-up roller 4 winds up the nonwoven fabric 5 as it rotates. Specifically, a cutting assembly 7 is vertically slidably connected to the frame 1, and a cutting table 6 is fixedly connected to the frame 1. The cutting assembly 7 slides downwards and cooperates with the cutting table 6 to cut the nonwoven fabric 5. The cutting assembly 7 is connected to the frame 1 via an adjustment mechanism 9, and the drive shaft of the motor 8 is connected to the adjustment mechanism 9 via a one-way transmission mechanism 13. In actual use, the motor 8 has two different working positions: forward and reverse rotation. Specifically, at the first station: when the drive shaft of the motor 8 rotates forward, it drives the take-up roller 4 to take up the non-woven fabric 5. At this station, the take-up roller 4 can rotate normally to take up the non-woven fabric 5. At this time, the cutting component 7 will not move downward and will not cut the non-woven fabric 5 that is being taken up, thus avoiding motion interference.

[0026] Second station: When the drive shaft of motor 8 reverses, the adjustment mechanism 9 is driven by the one-way transmission mechanism 13 to unlock the cutting component 7. The cutting component 7 then cuts the wound non-woven fabric 5. At this station, the winding roller 4 has completed the winding of the non-woven fabric 5. At this time, the motor shaft reverses and the adjustment mechanism 9 is driven by the one-way transmission mechanism 13 to unlock the cutting component 7. The unlocked cutting component 7 then cuts the non-woven fabric 5 to meet the work requirements.

[0027] Therefore, in this invention, the forward rotation of motor 8 drives the winding process, and the reverse rotation drives the unwinding of the cutting component 7, eliminating the need to stop the machine to switch processes. This solves the problem in traditional technology where the machine must be stopped after winding before cutting can begin, significantly improving production efficiency. Simultaneously, the unidirectional transmission mechanism 13 uses the forward and reverse rotation of motor 8 for winding and cutting respectively, eliminating the need for a separate drive device for cutting, avoiding the use of an additional power source, and reducing equipment costs and energy consumption. Furthermore, the cutting action is automatically triggered after winding is completed, requiring no manual intervention, enhancing the continuity of equipment operation, reducing idling and waiting time, and significantly improving equipment utilization.

[0028] In the embodiments provided by the present invention, the cutting assembly 7 includes a cutting blade 71 that is vertically slidably connected to the frame 1. A connecting block 72 is fixedly connected to the cutting blade 71, and a plurality of cutting springs 73 are provided between the cutting blade 71 and the frame 1. When there is no external force, the elastic force of the cutting springs 73 drives the cutting blade 71 to move downward rapidly, cutting the wound non-woven fabric 5 to meet the work requirements. No separate drive source is required, which reduces costs and energy consumption.

[0029] In the embodiments provided by the present invention, the adjustment mechanism 9 includes a sliding rod 91 slidably connected to the frame 1, a locking block 92 fixedly connected to the sliding rod 91, and a locking groove 99 adapted to the locking block 92 on the connecting block 72, the locking block 92 engaging with the locking groove 99; it also includes a rotating rod 97 rotatably connected to the frame 1, the rotating rod 97 being connected to the sliding rod 91 via a transmission unit. During use, the rotating rod 97 drives the sliding rod 91 to slide through the transmission unit, so that the sliding rod 91 drives the locking block 92 to slide out from the locking groove 99 where there is a working time difference between the two, and the elastic force of the cutting spring 73 drives the cutting blade 71 to move downward rapidly, cutting the wound non-woven fabric 5 to meet the work requirements without the need for a separate drive source control.

[0030] In the embodiment provided by the present invention, a pressing part 10 is vertically slidably connected to the frame 1, and the pressing part 10 is transmittedly connected to the rotating rod 97; during the stroke in which the sliding rod 91 drives the locking block 92 to slide out from the locking groove 99 and unlock the cutting blade 71, the pressing part 10 moves downward to press and fix the already wound non-woven fabric 5. By using the unlocking stroke to drive the pressing part 10, no additional power is required, saving energy and reducing costs while preventing the non-woven fabric 5 from scattering after winding, further improving the stability of the non-woven fabric 5 during cutting.

[0031] In the embodiments provided by the present invention, the extrusion section 10 includes an extrusion plate 101, an extrusion frame 102 fixedly connected to the extrusion plate 101, a second rack 103 fixedly connected to the extrusion frame 102, and a second gear 104 provided on the rotating rod 97, the second gear 104 meshing with the second rack 103; an extension block 105 fixedly connected to the second rack 103, and a positioning spring 106 provided between the extension block 105 and the extrusion, the elastic force of the positioning spring 106 driving the extrusion section 10 to retract into the frame 1. Specifically, during use, when the rotating rod 97 rotates, the extrusion frame 102 slides downward through the cooperation of the second gear 104 and the second rack 103, so that the extrusion plate 101 moves downward to extrude the wound non-woven fabric 5, preventing the non-woven fabric 5 from scattering after cutting.

[0032] In the embodiments provided by the present invention, the transmission unit includes a first rack 94, a first gear 98 mounted on a rotating rod 97, the first gear 98 meshing with the first rack 94, and a sliding groove provided on the first rack 94. A sliding rod 91 is slidably connected to the first rack 94 through the sliding groove, and a buffer spring 96 is also provided between the sliding rod 91 and the sliding groove. A first elastic element 93 is provided between the locking block 92 and the frame 1, and a second elastic element 95 is also provided between the first rack 94 and the frame 1. More specifically, when the rotating rod 97 rotates, it drives the first gear 98 to rotate, which in turn drives the first rack 94 to slide horizontally, thereby causing the first rack 94 to slide on the frame 1. At this moment, the first rack 94 and the sliding rod 91 gradually separate. During this process, the second gear 104 and the second rack 103 work together to drive the extrusion frame 102 to slide downwards, so that the extrusion plate 101 moves downwards to extrude the rolled-up nonwoven fabric 5, preventing the nonwoven fabric 5 from scattering after cutting. After the first rack 94 slides to the limit position of the groove, it will drive the sliding rod 91 to slide, so that the sliding rod 91 drives the locking block to slide away from the locking groove 99, unlocking the cutting blade 71. At this time, the cutting spring 73 drives the cutting blade 71 to move downwards to cut the rolled-up nonwoven fabric 5, preventing the nonwoven fabric 5 from scattering after cutting.

[0033] In the embodiments provided by the present invention, a plurality of guide rollers 14 are rotatably connected to the frame 1 to serve as guides.

[0034] In the embodiments provided by the present invention, a linkage rod 12 is also provided on the rotating rod 97. The linkage rod 12 serves as an intermediate transition shaft, shortening the transmission chain and facilitating the arrangement of a one-way mechanism. The one-way transmission mechanism 13 is arranged between the linkage rod 12 and the rotating rod 97, and a synchronizing element 11 is provided between the linkage rod 12 and the drive shaft of the motor 8. The synchronizing element 11 (such as a chain / belt) enables long-distance synchronous transmission, adapting to the layout of large equipment. The one-way transmission element includes a wedge-shaped insert 131 slidably connected to the rotating rod 97. A compression spring 132 is provided between the wedge-shaped insert 131 and the rotating rod 97. A slot 133 is provided on the linkage rod 12, and the elastic force of the compression spring 132 drives the wedge-shaped insert 131 to engage in the slot 133.

[0035] The present invention also provides a nonwoven fabric processing technology, including the above-mentioned automatic nonwoven fabric slitting device, specifically including the following steps: S1: Install the non-woven fabric 5 that needs to be cut between the carrying roller 3 and the winding roller 4, in preparation for the winding and cutting operation; S2: Motor 8 starts. When the drive shaft of motor 8 rotates forward, it drives the take-up roller 4 to rotate and perform take-up operation on the non-woven fabric 5. S3: After the winding operation is completed, motor 8 stops rotating, and at this moment, winding roller 4 stops winding; S4: Motor 8 starts again. At this moment, the drive shaft of motor 8 reverses and drives the adjustment mechanism 9 to slide out of the cutting assembly 7, which has a working time difference between the two, through the synchronizing component 11 and the one-way transmission component. S5: After the adjustment mechanism slides out of the cutting assembly 7, the elastic force of the cutting spring 73 causes the cutting blade 71 to slide downwards to cut the wound non-woven fabric 5. S6: After slitting, the motor 8 stops rotating again, and the wound-up roller 4 can be removed from the frame 1.

[0036] It should be noted that all electrical equipment involved in this application can be powered by batteries or external power sources, and this application is equipped with a control system for controlling the operation of the entire equipment.
