[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a cutting device for processing non-woven bags. (Refer to...) Figure 1-5A cutting device for processing non-woven bags includes a workbench 1, a support frame 2 installed on the right side of the end face of the workbench 1, a hydraulic cylinder 3 installed on the inner end face of the support frame 2, a disassembly and assembly structure 4 provided on the end face of the hydraulic cylinder 3, a cutting blade 5 installed on the disassembly and assembly structure 4, and a protective structure 6 installed on the workbench 1. The disassembly and assembly structure 4 includes a fixed shell 41. A first U-shaped frame 42 and a T-shaped plate 43 slidably connected to the inner cavity of the fixed shell 41 are symmetrically mounted on the end face of the fixed shell 41. The first U-shaped frame 42 is slidably connected to a limit rod 44 through a connecting hole. A ring 45 is installed on the outer wall of the limit rod 44. A sleeve 46 is rotatably connected to the outside of the ring 45. A return spring 47 is installed on the sleeve 46 and located on the outer wall of the limit rod 44. A rotating rod 48 is installed at the upper end of the limit rod 44. A vertical plate 49 is installed on the end face of the first U-shaped frame 42. Through the design of the disassembly and assembly structure 4, the function of quickly replacing the worn cutting blade 5 is realized, which solves the problem that most cutting blades of existing non-woven bag processing cutting devices are fixedly mounted on the device, and the blades are easy to wear after long-term use, making it inconvenient to replace the worn blades. This improves the cutting blade replacement efficiency.

[0019] Reference Figure 1 and Figure 5 A guide frame 7 is installed on the inner cavity end face of the support frame 2, and a slide rod 8 is symmetrically installed on the end face of the fixed shell 41. The driving end of the hydraulic cylinder 3 passes through the guide frame 7, and the guide frame 7 is slidably connected to the outer wall of the slide rod 8 through the connecting hole. A second U-shaped frame 9 is installed on the end face of the worktable 1, and a cylinder 10 is installed on the end face of the second U-shaped frame 9. A pressure plate 11 is provided on the driving end of the cylinder 10 and located in the inner cavity of the second U-shaped frame 9. A support leg 12 is installed at the bottom of the worktable 1 and located at the corner. A cutting groove 101 is opened on the worktable 1. The non-woven bag is inserted into the second U-shaped frame 9, cylinder 10 and pressure plate 11 through the second U-shaped frame 9 from the bottom of the pressure plate 11. The cylinder 10 is activated to extend downwards and the pressure plate 11 is moved down to fix the non-woven bag. This can prevent the non-woven bag from moving during the cutting process and causing the cutting to deviate, thus making the cutting device more effective. Reference Figures 1-4 The upper end of the cutting blade 5 is connected to the bottom of the T-shaped plate 43, the end face of the fixed shell 41 is connected to the drive end of the hydraulic cylinder 3, the inner end face of the first U-shaped frame 42 is connected to the upper end of the return spring 47, and the inner wall of the sleeve 46 is slidably connected to the outer wall of the limiting rod 44; a fixed insertion hole 431 adapted to the limiting rod 44 is provided on the T-shaped plate 43, and the lower end of the limiting rod 44 passes through the fixed shell 41 and is connected to the fixed insertion hole 431; a slot 491 is provided on the vertical plate 49, and the slot 491 is adapted to the rotating rod 48; With the slot 491, when the rotating rod 48 moves up and rotates, the outer wall of the rotating rod 48 is placed in the slot 491, thereby fixing the rotating rod 48 and allowing the rotating rod 48 to move out of the fixed insertion hole 431 with the limiting rod 44, thus facilitating the replacement of the T-shaped plate 43 and the cutting blade 5. Reference Figure 1 and Figure 5 The protective structure 6 includes a fixed frame 61, a servo motor 62 installed at the bottom center of the fixed frame 61, a screw 63 provided at the drive end of the servo motor 62, a lifting plate 64 connected to the screw 63 by a thread, guardrails 65 symmetrically installed on the front and rear side walls of the lifting plate 64, and sliders 66 installed on the side walls of the guardrails 65; the bottom of the worktable 1 is rotatably connected to the upper end of the screw 63 through a connecting hole, the fixed frame 61 is provided with a sliding groove 611 that is slidably connected to the slider 66, and a through groove 102 is provided on the worktable 1 corresponding to the guardrails 65; Working principle: When replacing the worn cutting blade 5, the operator drives the rotating rod 48 upwards, which in turn moves the limiting rod 44 upwards. Simultaneously, the rotating rod 48 rotates the limiting rod 44, which in turn moves the ring 45 upwards and rotates inside the sleeve 46. The sleeve 46 moves upwards and compresses the return spring 47, causing the outer wall of the rotating rod 48 to rotate to the end face of the vertical plate 49 and be placed in the slot 491. At this time, the lower end of the limiting rod 44 moves out of the fixed insertion hole 431. Then, the cutting blade 5 is driven forward or backward, or backward. The cutting blade 5, along with the T-shaped plate 43, moves out of the fixed housing 41. A new cutting blade 5 and T-shaped plate 43 are then replaced. The cutting blade 5 drives the T-shaped plate 43 from the front or rear of the fixed housing 41. Slide in and align the two sets of fixed insertion holes 431 with the lower ends of the two sets of limiting rods 44. Then drive the rotating rod 48 to move out of the slot 491. Then rotate and move the rotating rod 48 away from the end face of the vertical plate 49. Then release the rotating rod 48. Under the reset action of the reset spring 47, the reset spring 47 pushes the sleeve 46 to move in the opposite direction. The sleeve 46 drives the lower end of the limiting rod 44 into the fixed insertion hole 431 through the ring 45 and locks the T-shaped plate 43. This realizes the function of quick replacement of the cutting knife 5. It solves the problem that most of the cutting knives of the existing non-woven bag processing cutting devices are fixedly installed on the device. After long-term use, the knives are easy to wear and it is inconvenient to replace the worn knives. This improves the cutting knife replacement efficiency. When the non-woven bag is fixed on the workbench 1, the servo motor 62 is started to rotate forward. The servo motor 62 drives the screw 63 to rotate, and the screw 63 drives the lifting plate 64 to move upward. With the two sets of sliders 66 sliding in the slide groove 611, the lifting plate 64, along with the two sets of guardrails 65, moves upward from the through groove 102 until the end face of the lifting plate 64 is in contact with the bottom of the workbench 1. The two sets of guardrails 65 extend to the front and rear sides of the cutting blade 5, isolating the hydraulic cylinder 3 between the front and rear sets of guardrails 65. Then, the hydraulic cylinder 3 is started to move downward, and the cutting blade 5 cuts the non-woven bag. This can prevent the worker from accidentally touching the cutting blade during the cutting operation, thus protecting the worker. This solves the problem that existing non-woven bag processing cutting devices lack protective devices, and if the worker accidentally touches the cutting blade, it will cause injury to the worker's body. This ensures that the physical and mental health of the workers is not harmed, and makes the cutting device more effective.
