Detailed implementation manners

[0028] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] As Figure 1 and Figure 2 shown, a lightweight and high-strength warp knitting fabric cutting device includes: a frame 1, a side frame 2 is connected to the first end of the frame 1, and an unwinding frame 3 is arranged on the top of the side frame 2. An unwinding roller 4 is detachably arranged on the unwinding frame 3, and the unwinding roller 4 is used for unwinding the fabric to be cut.

[0030] Specifically, as Figure 3 shown, the unwinding frame 3 includes a lower placing seat 31 and an upper placing seat 32. One end of the upper placing seat 32 is hinged to the lower placing seat 31, and the other end is detachably connected to the lower placing seat 31 through a screw 33. The unwinding roller 4 is rotatably arranged between the upper placing seat 32 and the lower placing seat 31. During use, the screw 33 can be rotated to open the upper placing seat 32 for installing and disassembling the winding roller 4.

[0031] The first support 5, the second support 6, the third support 7 and the fourth support 8 are sequentially arranged on the top of the frame 1 from the first end to the second end.

[0032] As Figure 4As shown, a first guide roller 9 is provided on a first support 5. The first guide roller 9 includes an upper roller 91 and a lower roller 92 arranged vertically. Both ends of the upper roller 91 are connected with guide sliders 93, and the guide sliders 93 are slidably arranged in sliding guide grooves 94 opened on the first support 5. A guide lead screw 95 is arranged in the sliding guide grooves 94. The guide lead screw 95 is in threaded cooperation with the guide sliders 93, and its top end extends above the first support 5 and is provided with an adjusting part at the top end. By means of the adjusting part, the guide lead screw 95 can be driven to rotate, driving the guide sliders 93 to lift in the sliding guide grooves 94, thereby driving the upper roller 91 to approach or move away from the lower roller 92 to clamp the fabric. Among them, the position of the lower roller 92 is fixed and cannot be lifted or lowered.

[0033] A second guide roller 10 is provided on a second support 6 to guide the fabric.

[0034] A tension support 11 is arranged between the first support 5 and the second support 6 on the frame 1, and a tension roller 12 is arranged on the tension support 11 to adjust the fabric tension.

[0035] As Figure 5 shown, a sliding groove 13 is opened on the tension support 11. An upper slider 14 and a lower slider 15 are slidably arranged in the sliding groove 13. The upper slider 14 is located above the lower slider 15, and the end of the tension roller 12 is connected with the lower slider 15. A spring 16 is arranged between the upper slider 14 and the lower slider 15, and both ends of the spring 16 are respectively connected with the upper and lower sliders.

[0036] A first lead screw 17 is arranged in the sliding groove 13. The first lead screw 17 is in threaded cooperation connection with the upper slider 14, and its bottom end extends below the tension support 11 and is provided with a rotating handle 18 at the bottom end. The center of the lower slider 15 is provided with an opening, and the first lead screw 17 is inserted into the opening and does not contact the lower slider 15.

[0037] By rotating the rotating handle 18, the first lead screw 17 can be driven to rotate. The first lead screw 17 drives the upper slider 14 to lift, changing the distance between the upper and lower sliders, adjusting the compression amount of the spring 16, and thus changing the fabric tension. The spring 16 can keep the fabric tension constant and avoid problems such as wrinkling and loosening caused by tension imbalance.

[0038] As Figure 6 shown, an upper feeding roller 19 and a lower feeding roller 20 are provided on a third support 7. Both ends of the upper feeding roller 19 are connected to a sliding block 21, and the sliding block 21 is slidably arranged in a sliding groove 22 opened on the third support 7. A second lead screw 23 is arranged in the sliding groove 22. The top end of the second lead screw 23 extends above the third support 7 and is provided with an adjusting part at the top end. By means of the adjusting part, the second lead screw 23 can be driven to rotate. The rotation of the second lead screw 23 can drive the sliding block 21 to lift, thereby changing the distance between the upper and lower feeding rollers to adapt to fabrics of different thicknesses.

[0039] The lower feeding roller 20 is driven by a driving motor 24 arranged on the frame 1. Specifically, one end of the lower feeding roller 20 extends outside the third support 7, and a first transmission wheel 28 is arranged at the end. The output end of the driving motor 24 is provided with a second transmission wheel 29. The first transmission wheel 28 and the second transmission wheel 29 are connected by belt drive.

[0040] As Figure 7 shown, a cutting knife 25 is arranged on the fourth support 8, and the cutting knife 25 is driven by a cylinder 26 arranged at the top of the fourth support 8 to move up and down for cutting. A cutting knife table 27 is arranged below the cutting knife 25, and a cutting knife groove 30 corresponding to the cutting knife 25 is arranged on the cutting knife table 27.

[0041] On one side of the cutting knife table 27 away from the third support 7, a discharge plate 34 inclined downward is arranged, so that the cut fabric automatically falls under the action of its gravity. A receiving box 35 is arranged below the discharge plate 34 for collecting the cut fabric.

[0042] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field according to the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
