Description

Technical Field

[0001] The utility model belongs to the technical field of non-woven fabric production, and particularly relates to a non-woven fabric cutting device. Background Technique

[0002] Non-woven fabric is also called non-woven material, non-woven fabric, or non-woven cloth. It is made of fibers arranged in a directional or random manner through friction, interlocking, adhesion, or a combination of these methods, with the essence being "non-woven". Non-woven fabric exists in the form of fibers in the cloth, while the woven cloth exists in the form of yarns in the cloth. This is also a main feature that differentiates non-woven fabric from other fabrics. No individual thread ends can be pulled out from non-woven fabric;

[0003] After the production of non-woven fabric is completed, it is necessary to cut the non-woven fabric according to the required size of the object by a cutting device to facilitate subsequent processing of the non-woven fabric.

[0004] However, when the cutting device cuts the non-woven fabric, the cutting equipment can only cut the non-woven fabric after it is laid flat. However, since the cutting device cannot tighten the non-woven fabric, the size of the non-woven fabric after cutting is prone to deviation, and it is necessary to manually cut the non-woven fabric a second time, resulting in the inability to accurately control the cutting size during the cutting of the non-woven fabric. Summary of the Utility Model

[0015] Advantageous Effects

[0016] The technical solution provided by the present utility model has the following advantageous effects compared with the prior art:

[0017] By means of the non-woven fabric stretching structure provided in the present utility model, one end of the non-woven fabric is fixed by the non-woven fabric stretching structure, then the non-woven fabric stretching structure moves to one side to stretch the non-woven fabric, and then the pressing plate and the fitting plate fix the non-woven fabric. The outward movement of the non-woven fabric stretching structure can straighten the non-woven fabric, which is convenient for subsequent cutting of the non-woven fabric and avoids deviation in the size of the non-woven fabric after cutting due to wrinkles in the non-woven fabric;

[0029] Referring to Figures 1-4 , a non-woven fabric cutting device shown includes a mounting plate 1, transmission lead screws 5 are arranged on both sides of the mounting plate 1, sliding grooves 4 are formed on both sides of the mounting plate 1, and a non-woven fabric stretching structure 6 is arranged between the two transmission lead screws 5;

[0030] The non-woven fabric stretching structure 6 includes a moving frame 601 and a second electric telescopic rod 606. An auxiliary plate 604 is arranged on one side of the moving frame 601. Slide holes 605 are formed on both sides of the top of the moving frame 601. The second electric telescopic rod 606 is arranged in the middle of the top of the mounting plate 1. The output end of the second electric telescopic rod 606 is provided with a lifting frame 607. The lifting frame 607 is slidably connected to the inner wall of the slide hole 605. One end of the lifting frame 607 is provided with a clamping plate 608. Auxiliary strips 609 are arranged on both sides of the bottom of the clamping plate 608. The clamping plate 608 is arranged directly above the auxiliary plate 604.

[0031] Further, in the above technical solution, a bracket 2 is arranged at the bottom of one end of the mounting plate 1. A belt feeding device 3 is arranged between the mounting plate 1 and the bracket 2. A blanking groove 7 is formed in the middle of the mounting plate 1. The blanking groove 7 is arranged directly below the belt feeding device 3. The cut non-woven fabric contacts the conveyor belt in the belt feeding device 3 through the blanking groove 7. The motor drives the belt pulley to rotate, and the belt pulley drives the conveyor belt to move forward, so that the conveyor belt drives the non-woven fabric to move, realizing the discharging of the cut non-woven fabric.

[0032] Further, in the above technical solution, connection blocks 602 are arranged at both ends of the moving frame 601. The connection blocks 602 are slidably connected to the sliding grooves 4. A matching hole 603 is formed inside the connection blocks 602. The matching hole 603 cooperates with the transmission lead screw 5. The motor is started, and the motor drives the transmission lead screw 5 to rotate. The transmission lead screw 5 drives the connection block 602 to slide inside the sliding groove 4 through the matching hole 603, so that the connection block 602 drives the moving frame 601 to move to stretch the non-woven fabric.

[0033] Further, in the above technical solution, on both sides of the outer wall of the mounting plate 1, there are first electric telescopic rods 8. The output end of the first electric telescopic rod 8 is provided with an adjustment frame 9. One end of the adjustment frame 9 is provided with a pressing plate 10. Right below the pressing plate 10, there is a fitting plate 11. Both ends of the fitting plate 11 are connected to both sides of the inner wall of the mounting plate 1. When the first electric telescopic rod 8 is started, the first electric telescopic rod 8 drives the adjustment frame 9 to move downward, and the adjustment frame 9 drives the pressing plate 10 to move downward. Then, the pressing plate 10 and the fitting plate 11 cooperate to clamp the non-woven fabric between the pressing plate 10 and the fitting plate 11.

[0034] Further, in the above technical solution, at the bottom of the inner wall of the mounting plate 1, there is a placing strip 12. Right above the placing strip 12, there is a cutting blade 13. The cutting blade 13 is slidably connected to the mounting plate 1. Both ends of the cutting blade 13 are provided with electric telescopic rods, and the electric telescopic rods are connected to the inner wall of the mounting plate 1. When it is necessary to cut the non-woven fabric, the electric telescopic rods are started, and the electric telescopic rods drive the cutting blade 13 to move downward. Then, the cutting blade 13 cuts the non-woven fabric.

[0035] The working principle of this utility model:

[0036] Refer to the attached drawings of the specification Figures 1-4 First, when it is necessary to cut the non-woven fabric through the cutting device, the non-woven fabric is passed through the pressing plate 10, the fitting plate 11, the cutting blade 13, and the placing strip 12. Then, the second electric telescopic rod 606 is started, and the second electric telescopic rod 606 drives the lifting frame 607 to move downward. The lifting frame 607 drives the clamping plate 608 to move downward, so that the clamping plate 608 drives the auxiliary strip 609 and the auxiliary plate 604 to clamp one end of the non-woven fabric.

[0037] Then, the motor is started. The motor drives the transmission lead screw 5 to rotate. The transmission lead screw 5 drives the connecting block 602 to slide on the inner wall of the chute 4 through the mating hole 603, and the connecting block 602 drives the moving frame 601 to move outward, so that the moving frame 601 drives the non-woven fabric to be stretched. Then, the first electric telescopic rod 8 is started, and the first electric telescopic rod 8 drives the adjustment frame 9 to move downward. The adjustment frame 9 drives the pressing plate 10 to clamp the non-woven fabric between the pressing plate 10 and the fitting plate 11. At the same time, the non-woven fabric stretching structure 6 continues to move outward to tighten the non-woven fabric. After that, the electric telescopic rod is started, and the electric telescopic rod drives the cutting blade 13 to move downward to cut the non-woven fabric.

[0038] After that, the second electric telescopic rod 606 drives the auxiliary strip 609 to reset, so that the auxiliary strip 609 and the auxiliary plate 604 release one end of the non-woven fabric, and the non-woven fabric falls onto the top of the feeding device 3. The feeding device 3 discharges the cut non-woven fabric.
