Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric slitting technology, and in particular to a nonwoven fabric production slitting machine with adjustable blade distance. Background Technology

[0002] After production, nonwoven fabrics are typically quite wide and require a slitting machine to cut them into smaller rolls. A nonwoven fabric slitting machine is used to cut wide nonwoven fabrics into multiple narrow strips. Depending on different production needs, it performs edge trimming, slitting, and other processing on the wide strips to meet the requirements of nonwoven fabric slitting.

[0003] Currently, when using nonwoven fabric production slitting machines, the distance between the slitting blades needs to be adjusted according to the width to be slit.

[0004] A publicly available technical solution, CN221940927U, discloses a nonwoven fabric slitting machine, including a frame and a movable block. The frame is movably connected to a mounting frame, which is U-shaped. The mounting frame is connected to a first fixed square rod, a second fixed square rod, and a positioning rod. The movable block is slidably connected to the positioning rod and has a sliding groove. The movable block is slidably connected to the first fixed square rod through the sliding groove. The movable block is threadedly connected to a threaded rod, which is rotatably connected to a clamping plate. The clamping plate abuts against the side wall of the sliding groove. The movable block is connected to a first connecting plate, and the second fixed square rod is slidably connected to a second connecting plate. The first and second connecting plates are jointly connected to slitting blades. The spacing between adjacent sets of slitting blades can be adjusted, thus enabling the processing of nonwoven fabrics of different widths according to actual conditions. The overall structure is simple, greatly improving the flexibility and practicality of the device.

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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 3A nonwoven fabric production slitting machine with adjustable blade distance includes a device base plate 1, a feeding roller 2 for placing nonwoven fabric is installed on the top left side of the device base plate 1, and a support frame 4 fixed to the top middle of the device base plate 1 is provided on one side of the feeding roller 2. A winding roller 3 for winding nonwoven fabric is installed on the top right side of the device base plate 1, and a slitting assembly 7 is provided at the bottom of the support frame 4.

[0028] The slitting assembly 7 includes multiple connecting rods 703 connected end to end by pins. The end of each connecting rod 703 is rotatably connected to an end rotating rod 705, and a middle rotating rod 704 is rotatably connected at the connection point of two sets of connecting rods 703. The bottom of the middle rotating rod 704 is connected to a second guide slider 707 via a bearing, and a slitting blade 701 is fixed to the bottom of the second guide slider 707.

[0029] The top of the end rotating rod 705 is connected to the first guide slider 706 via a bearing, and the inside of the first guide slider 706 is connected to the bidirectional lead screw 708 via a threaded sleeve. One end of the bidirectional lead screw 708 is fixed to the power output end of the lead screw motor 702. Multiple connecting rods 703 form a scissor structure, and a lifting component 6 is provided on the outside of the cutting component 7.

[0030] By adopting the above technical solution, the nonwoven fabric roll is placed on the feeding roller 2. After the nonwoven fabric is unrolled, it is cut by the slitting component 7 and wound onto the winding roller 3 for winding. When it is necessary to adjust the spacing between the slitting blades 701, the lead screw motor 702 can be started. The power output end of the lead screw motor 702 drives the bidirectional lead screw 708 to rotate. Under the action of the first guide slider 706 on the surface of the bidirectional lead screw 708, the position of the end rotating rod 705 can be adjusted. When the end rotating rod 705 slides, it can drive the scissor mechanism composed of the connecting rod 703 to stretch, thereby driving the middle rotating rod 704 to adjust its position. At this time, the distance between the second guide sliders 707 on the middle rotating rod 704 changes, thereby adjusting the spacing between the slitting blades 701. Through the slitting component 7, under the action of the scissor mechanism composed of the connecting rod 703, the distance between the middle rotating rods 704 can be adjusted when the connecting rod 703 is stretched, thereby adjusting the spacing between the slitting blades 701, making the adjustment more convenient and faster.

[0033] By adopting the above technical solution, the slitting assembly 7 can be height adjusted under the action of the lifting assembly 6. The lifting cylinder 601 is activated, which drives the lifting plate 602 to move up and down, thereby causing the lifting plate 602 to slide inside the lifting slide groove 603. Before adjusting the spacing of the slitting blades 701, the slitting assembly 7 can be moved downward so that the slitting blades 701 are inserted into the corresponding support groove 501. Then, the slitting blades 701 drive the support groove 501 to slide on the top of the support base plate 502. The support groove 501 has a certain depth. The position of the cutting edge of the slitting blade 701 can be adjusted by adjusting the depth of the slitting blades 701 inserted into the support groove 501. The height of the slitting blades 701 can be adjusted by the lifting assembly 6.

[0034] Working principle: The non-woven fabric roll is placed on the feeding roller 2. After the non-woven fabric is unrolled, it is slit by the slitting component 7 and wound onto the winding roller 3 for winding. The slitting component 7 can be height adjusted under the action of the lifting component 6. The lifting cylinder 601 is activated, which drives the lifting plate 602 to move up and down, thereby causing the lifting plate 602 to slide inside the lifting groove 603. Before adjusting the spacing of the slitting blades 701, the slitting component 7 can be moved downward so that the slitting blades 701 are inserted into the corresponding support groove 501. Then, the slitting blades 701 drive the support groove 501 to slide on the top of the support base plate 502. 1. It has a certain depth, and the cutting edge position of the slitting blade 701 can be adjusted by adjusting the depth of the insertion of the slitting blade 701 into the support groove 501. The power output end of the lead screw motor 702 drives the bidirectional lead screw 708 to rotate. Under the action of the first guide slider 706 on the surface of the bidirectional lead screw 708, the position of the end rotating rod 705 can be adjusted. When the end rotating rod 705 slides, it can drive the scissor mechanism composed of the connecting rod 703 to be stretched, thereby driving the middle rotating rod 704 to adjust its position. At this time, the distance between the second guide sliders 707 on the middle rotating rod 704 changes, thereby adjusting the spacing between the slitting blades 701.
