Technical Field
[0001] This utility model relates to the field of nonwoven fabric production technology, specifically to a nonwoven fabric production slitting machine that facilitates tool replacement. Background Technology
[0002] After production, nonwoven fabrics need to be slit, usually using a slitting machine. Currently used slitting machines mostly have fixed slitting blades. When cutting multiple layers of nonwoven fabric at once, the blades become dull and damaged due to prolonged direct contact with the fabric, hindering the cutting process. Therefore, designing a nonwoven fabric slitting machine that allows for easy blade replacement is crucial. For example:
[0003] This invention, authorized by announcement number CN221587546U, describes a nonwoven fabric slitting machine. It addresses the problem of existing nonwoven fabric slitting machines, which are devices specifically designed for cutting nonwoven fabrics. These machines use mechanical blades or cutting devices to cut the fabric to a fixed size. Typically, the cut nonwoven fabric is directly stacked in front of the slit without auxiliary stacking devices. This leads to uneven edges on multiple stacks, time-consuming manual alignment, and uneven surfaces during stacking, causing deformation if not properly compressed. Furthermore, existing nonwoven fabric slitting machines lack a mechanism for neatly collecting the cut material. This invention addresses this issue by incorporating a limiting device. Pulling the limiting block to the left moves it along the surface of the stabilizing block. The force generated by this movement causes the spring to elastically deform. The spring's restoring force then engages the limiting block within the limiting groove, thus restricting the position of the receiving box.
[0004] Based on existing solutions and actual production and processing applications, existing nonwoven fabric slitting machines have the following shortcomings, such as:
[0005] While existing nonwoven fabric slitting machines can neatly collect the slitting material, the slitting blades are mostly fixed, and the blades are in direct contact with the nonwoven fabric for a long time, which will cause the blades to become dull and damaged, which is not conducive to the cutting work. Therefore, this utility model provides a nonwoven fabric slitting machine that is easy to replace the blades to solve the above-mentioned problems. Utility Model Content
[0006] The purpose of this utility model is to provide a nonwoven fabric production slitting machine that facilitates blade replacement, in order to solve the problem mentioned in the background art that although the existing nonwoven fabric production slitting machines can neatly collect the slitting materials, the slitting blades are mostly fixedly connected, and the blades are in direct contact with the nonwoven fabric for a long time, which will cause the blades to become damaged and dull, which is not conducive to the cutting work.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a non-woven fabric production slitting machine that facilitates blade replacement, comprising a load-bearing plate, a slitting groove being provided inside the load-bearing plate, a slitting blade being provided above the load-bearing plate, and a connecting rod being provided outside the slitting blade;

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.
[0029] Please see Figure 1-6 This utility model provides a technical solution: a non-woven fabric production slitting machine that facilitates blade replacement, including a load-bearing plate 1, a slitting groove 2, a slitting blade 3, a connecting rod 4, a support base 5, a storage rack 6, a base plate 7, a self-locking wheel 8, a support column 9, a top plate 10, an electric telescopic rod 11, a protective cover 12, a control room 13, 14, a drive rod 15, a drive block 16, a connecting seat 17, a mounting frame 18, a limiting rod 19, a limiting block 20, a protective frame 21, a non-woven fabric body 22, a positioning frame 23, a positioning bolt 24, and a protective door 25.
[0030] Specific examples Figure 1 , Figure 3 and Figure 4 As shown, firstly, the self-locking wheel 8 connected to the lower end of the base plate 7 is placed on a horizontal surface, with the bottom end of the self-locking wheel 8 contacting the upper end of the horizontal surface. The upper end of the base plate 7 is connected to the support base 5, and the upper end of the support base 5 is connected to the lower end of the load-bearing plate 1. The support base 5 has an inclined structure and is symmetrically arranged about the center line of the load-bearing plate 1. A storage rack 6 is provided inside the support base 5, which evenly divides the space between the support base 5, the load-bearing plate 1, and the base plate 7. A protective door 25 is provided at the front end of the support base 5. When the protective door 25 is opened, miscellaneous items can be stored in the evenly divided space of the storage rack 6. The interior of the load-bearing plate 1 has equally spaced cutting grooves 2. Place the nonwoven fabric body 22 at the end, select two sets of positioning frames 23, and place them directly above the load-bearing plate 1 after the inner ends of the two sets of positioning frames 23 are in contact. Press the positioning frames 23, at which time the bottom end of the positioning frame 23 contacts the upper end of the load-bearing plate 1. Pull the positioning frames 23 outward, so that the inner end of the positioning frame 23 and the upper end of the nonwoven fabric body 22 are in friction. The positioning frame 23 and the nonwoven fabric body 22 are slidably connected. When the positioning frame 23 moves to the appropriate position, screw the positioning bolt 24 at the connection between the positioning frame 23 and the load-bearing plate 1. The positioning bolt 24 fastens the positioning frame 23 to the load-bearing plate 1. At this time, the nonwoven fabric body 22 is laid flat and positioned on the load-bearing plate 1, which facilitates the flat laying and positioning function of the nonwoven fabric production slitting machine for nonwoven fabric.
[0031] Specific examples Figure 1 , Figure 3 and Figure 6As shown, the protective frame 21 is placed horizontally. After aligning the edge of the protective frame 21 with the left and right inner walls of the mounting frame 18, it is pushed. Friction occurs between the outer wall of the protective frame 21 and the inner wall of the mounting frame 18, causing the mounting frame 18 and the protective frame 21 to slide together until the upper surface of the protective frame 21 is in complete contact with the mounting frame 18. At this point, a limiting rod 19 is vertically inserted through the connection between the mounting frame 18 and the protective frame 21, and limiting blocks 20 are screwed onto the threaded structures at both ends of the limiting rod 19, causing the limiting blocks 20 to tighten inwards. The mounting frame 18 and... The connection gap between the protective frames 21 is shortened, and the mounting frame 18 is fastened to the protective frame 21. A connecting rod 4 is provided on the inner side of the protective frame 21, and the connecting rod 4 is arranged in a left-right correspondence with the slitting blade 3. The slitting blade 3 is arranged in a vertical correspondence with the slitting groove 2 opened inside the load-bearing plate 1. When replacing the slitting blade 3, the limiting block 20 is unscrewed, and the limiting rod 19 is pulled out from the inside of the mounting frame 18 and the protective frame 21. The mounting frame 18 and the protective frame 21 are in a locked state, which facilitates the quick replacement of the blades of the nonwoven fabric production slitting machine.
[0032] Specific examples Figure 1 , Figure 2 and Figure 5 As shown, a support column 9 is provided at the upper end of the load-bearing plate 1, and the upper end of the support column 9 supports the top plate 10. The electric telescopic rod 11 at the lower end of the top plate 10 is opened, causing the entire structure at the lower end to move. The slitting blade 3 gradually approaches the non-woven fabric body 22. When the slitting blade 3 passes through the non-woven fabric body 22 and penetrates into the slitting groove 2, the electric telescopic rod 11 is closed. Then, the control motor 14 is turned on. The control motor 14 is located inside the control room 13, which is equipped with the rear end of the protective cover 12. After the control motor 14 is powered on, it drives... The drive rod 15 connected to the front end rotates. The drive rod 15 has a threaded structure on its outside and passes through the inside of the drive block 16. The drive block 16 moves under the drive of the drive rod 15. The top of the drive block 16 is slidably connected to the protective cover 12. The drive block 16 drives the connecting seat 17 connected below and its whole to move forward. The slitting blade 3 cuts the nonwoven fabric body 22, which makes it easy for the nonwoven fabric production slitting machine to realize the function of equidistant slitting of nonwoven fabric. This is the usage method of the nonwoven fabric production slitting machine that is easy to replace the blade.
