[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figure 1 As shown, a cutting device for composite fiber cloth, such as Figures 1 to 5 As shown, the present invention provides a cutting device for composite fiber cloth, comprising:

[0034] A cutting platform 1, used for supporting the fiber cloth;

[0035] A material roller 2 is arranged at the front end of the cutting platform 1, and a plurality of material rollers 2 are provided, and the plurality of material rollers 2 are parallel to each other;

[0036] The cutting blade 3 is slidably arranged above the cutting platform 1 through a blade drive electric rail 4 located behind the material roller 2. The cutting blade 3 reciprocates along the blade drive electric rail 4 to cut the multi-layer fiber cloth on the cutting platform 1 below.

[0037] The pressure roller 5 is rotatably arranged above the cutting platform 1, and is in clearance fit with the cutting platform 1. The pressure roller 5 makes the multi-layer fiber cloth released by multiple material rollers 2 fit together by squeezing. The pressure roller 5 is arranged in front and behind the cutter head driving electric rail 4.

[0038] Specifically, after the multiple material rollers 2 are aligned, the multiple layers of fiber cloth pulled out from the multiple material rollers 2 pass through the front pressure roller 5, the cutting blade 3 and the rear pressure roller 5 in turn. The front and rear pressure rollers 5 press the multiple layers of fiber cloth together so that the multiple layers of fiber cloth are close to each other by friction, so as to avoid misalignment between the multiple layers of fiber cloth when the cutting blade 3 is cutting, resulting in uneven cuts.

[0039] To facilitate the assembly and disassembly of the material roller 2, the cutter head driving rail 4 and the pressure roller 5 with the cutting platform 1, brackets 6 are provided on both sides of the cutting platform 1, and the material roller 2, the cutter head driving rail 4 and the two ends of the pressure roller 5 are provided on the brackets 6 on both sides.

[0040] In addition, the pressing roller 5 is rotatably arranged on the bracket 6 through the sliding bearing 7, and the bracket 6 is vertically provided with a vertical groove 8 for the sliding bearing 7 to slide. The bracket 6 is provided with a lifting mechanism 9 connected to the outer side of the sliding bearing 7, that is, the sliding bearing 7 is driven to rise and fall through the lifting mechanism 9, so that the pressing roller 5 presses and releases the multi-layer fiber cloth. It is convenient for the multi-layer fiber cloth to pass under the pressing roller 5, and it is convenient to adjust the height and pressing force of the pressing roller 5 according to the number and type of fiber cloth.

[0041] In order to prevent the multi-layer fiber cloth from shifting when the cutting knife 3 moves back and forth left and right for cutting, both ends of the pressure roller 5 are provided with anti-deflection rings 10. The difference between the inner diameter and the outer diameter of the anti-deflection ring 10 is adapted to the thickness of the multi-layer fiber cloth after being pressed and fitted by the pressure roller 5. The spacing between the anti-deflection rings 10 at both ends is adapted to the width of the fiber cloth to prevent the multi-layer fiber cloth from shifting when being cut, so as to prevent uneven cuts caused by lateral deviation of the multi-layer fiber cloth during the cutting process, and even cause the cutting knife 3 to get stuck.

[0042] In addition, the pressure roller 5 includes a front roller 501 located in front of the cutter head driving electric rail 4 and a rear roller 502 located behind the cutter head driving electric rail 4. The outer periphery of the stop ring 10 on the front roller 501 has a ring-shaped cutting edge 11, and the stop ring 10 with the cutting edge 11 is fixedly connected to the front roller 501 in the circumferential direction.

[0043] After the front roller 501 presses the multi-layer fiber cloth, as the multi-layer fiber cloth is conveyed, the front roller 501 will drive the stop ring 10 to rotate, and because the stop ring 10 is in close contact with the side of the multi-layer fiber cloth, the stop ring 10 with a cutting blade 11 on the side can rotate to cut off the burrs of the multi-layer limiting cloth, thereby reducing the subsequent burr removal process, thereby achieving the purpose of improving production efficiency and reducing equipment costs.

[0044] Among them, the trimming blade 11 is a single-sided blade, and the inclined surface of the trimming blade 11 is located on the outside of the stop ring 10 away from the center of the front roller 501. On the one hand, the stop ring 10 with a flat surface on the inner side can be tightly attached to the side of each layer of fiber cloth. On the other hand, the trimming blade 11 has an inclined surface only on the outer side, so that the cut burrs can be pushed to the outside by the trimming blade 11, avoiding the multi-layer limiting parts carrying the cut burrs, thereby facilitating the appearance of the fiber cloth product.

[0045] Furthermore, when it is necessary to cut off the redundant side edges of the multi-layer fiber cloth according to the customized size requirements, the spacing between the stop rings 10 at both ends of the front roller 501 is adjusted, and then the lifting mechanism 9 drives the front roller 501 to descend until the cutting blade 11 of the stop ring 10 cuts the multi-layer fiber cloth. At this time, the front roller 501 also presses the multi-layer fiber cloth. Thereafter, as the multi-layer fiber cloth is conveyed, the cutting blade 11 will continue to cut the redundant side edges of the multi-layer fiber cloth passing by.

[0046] Among them, the side surfaces at both ends of the front roller 501 are axially provided with sliding grooves 15, and a plurality of sliding grooves 15 are evenly spaced around the circumference of the front roller 501. The inner circumference of the deflection prevention ring 10 is provided with a plurality of strip-shaped sliders 16 that slide with the sliding grooves 15, thereby realizing the circumferential fixation and axial sliding connection between the deflection prevention ring 10 and the front roller 501.

[0047] In addition, the strip slider 16 protrudes from the end of the stop ring 10, and the stop ring 10 and the front roller 501 are fixed by a stop ring fixing screw 17 set on the strip slider 16. A plurality of threaded holes 18 for the stop ring fixing screw 17 to be screwed in are arranged at intervals on the wall of the slide groove 15.

[0048] Since the front roller 501 does not press the multi-layer fiber cloth when the trimming blade 11 first cuts the multi-layer fiber cloth, in order to reduce the difficulty of the trimming blade 11 when cutting the multi-layer fiber cloth for the first time and the cutting accuracy, a pre-pressing plate 12 is arranged in front of the front roller 501 and located above the cutting platform 1. The two ends of the pre-pressing plate 12 are arranged on the two side brackets 6. The multi-layer fiber cloth released by multiple material rollers 2 passes through the gap between the pre-pressing plate 12 and the cutting platform 1 to make the multi-layer fiber cloth close to each other. At this time, the pre-pressing plate 12 does not press the multi-layer fiber cloth so that the multi-layer fiber cloth can be transported normally.

[0049] Furthermore, in order to prevent the multi-layer fiber cloth from deviating in front of the trimming blade 11, which would reduce the trimming accuracy of the multi-layer fiber cloth and even cause the fiber cloth to be scrapped, trimming anti-deviation rollers 13 supported on the cutting platform 1 are provided at both ends of the pre-pressing plate 12.

[0050] In addition, both ends of the pre-pressing plate 12 are slidably sleeved with adjustment sleeves 21, and the adjustment sleeve 21 and the pre-pressing plate 12 are fixed to the pre-pressing plate 12 by anti-deflection roller fixing bolts 19. A slide rail 14 is arranged on the cutting platform 1 and below the pre-pressing plate 12. The bottom of the edge cutting anti-deflection roller 13 is rotatably arranged on the slider of the slide rail 14, so as to guide the edge cutting anti-deflection roller 13, and the top of the edge cutting anti-deflection roller 13 is rotatably arranged on the adjustment sleeve 21, so as to facilitate the movement of the adjustment sleeve 21 to adjust the position of the edge cutting anti-deflection roller 13.

[0051] In addition, a conveyor belt 20 is embedded on the cutting platform 1 and below the front roller 501 and the rear roller 502 . The conveyor belt 20 clamps and conveys the multi-layer fiber cloth by cooperating with the front roller 501 and the rear roller 502 .

[0052] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
