[0002] Cloth needs to be sized and cut, which is one of the most basic and key links in the production and manufacturing of the textile industry such as garments and home textiles. Sizing and cutting is to ensure the size accuracy, specification uniformity and quality qualification of the final product, so as to realize high-efficiency, low-cost and large-batch industrial production. For garments, the length, sleeve length, chest circumference and waist circumference must be accurate. If the size of the cutting piece is not accurate, the clothes sewn may be asymmetric, with sleeves of different lengths, which cannot be worn or seriously affects the appearance. Manual cutting is extremely low in efficiency and cannot meet the needs of modern mass production. Cloth is one of the main costs of textiles. Through accurate sizing and cutting, cloth can be used to the maximum extent, waste can be reduced, raw materials can be saved, and costs can be reduced.

[0023] Please refer to Figures 1-9 As shown in the drawings, the present application is a cloth cutting device convenient for cutting to size, which comprises a bottom plate 1, an arched frame 3 fixedly installed in the middle of the bottom plate 1, a turning rod 31 with a cross-shaped groove on the outer wall rotatably installed in the middle of the arched frame 3, a plurality of moving sleeves 32 equally spaced and slidably clamped on the turning rod 31, a cutting knife 33 fixedly installed on the outer side of the middle of the moving sleeve 32, an external frame 34 rotatably connected to the two sides of the moving sleeve 32 and arranged above the cutting knife 33, a size setting assembly arranged above the turning rod 31 to control the distance between the plurality of cutting knives 33 to meet different cutting requirements, a conveying part arranged on one side of the arched frame 3 to pay off the rolled cloth, and a material collecting assembly arranged on the side of the arched frame 3 away from the conveying part to wind the cut cloth segments; The cloth on the conveying part is cut through the cutting knives 33, so that multiple groups of cutting knives 33 can cut the cloth in sections, and the size of the cloth cut between every two adjacent cutting knives 33 is consistent. The multiple moving sleeves 32 can move at equal intervals outside the rotating rod 31 through the setting of the sizing assembly, so that the spacing of the cutting knives 33 outside the multiple moving sleeves 32 can be adjusted to meet the different size requirements of the cloth cutting. The motor is turned on to drive the rotating rod 31 to rotate, and the multiple moving sleeves 32 are driven to rotate when the rotating rod 31 rotates, and the cutting knives 33 are synchronously driven to rotate when the moving sleeves 32 rotate, so that the cutting operation of the cloth is realized. The conveying part and the material collecting assembly cooperate to feed and convey the cloth during the cutting of the cutting knives 33, and simultaneously perform the winding operation on the multiple sections of the cloth, so that the wound cloth after the cutting is uniformly taken after the cutting is completed.

It should be noted that the middle outer frame 34 will not drive the cutting knives 33 to slide because the pressing force on both sides of the inclined plates 35 is consistent when the inclined plates 35 on both sides of the middle outer frame 34 are pressed by the pressing wheel 364. The number of cutting knives 33 in the present application is five, and the number of sliding pieces 371 on the guide rod 37 can be increased or decreased according to actual use requirements, and the number of cutting knives 33 can also be increased or decreased accordingly. When the lifting frame 361 moves up, the pressing wheel 364 on the mounting piece 363 cancels the pressing on the inclined plates 35, the spring loses the traction of the sliding piece 371 on the outer frame 34 at this time, and the multiple sliding pieces 371 are reset at this time.

[0027] The limiting assembly comprises a side piece one 61 slidably connected with a cross groove opened outside the material receiving rod 51, one side of the side piece one 61 is provided with a limiting cylinder 622 slidably connected with the material receiving rod 51, the limiting cylinder 622 is externally provided with a side piece two 62, the side piece two 62 is rotatably installed with an external ring 621 outside, one side of the external ring 621 away from the side piece one 61 is provided with an extension frame fixedly connected with the external frame 34, the extension frame is slidably installed with a pull rod 623 fixedly connected with the external ring 621, and the pull rod 623 is externally sleeved with a spring; When disassembling the roll cylinder 52, first, the material collecting frame 5 is disassembled on the arch-shaped frame 3, then the roll cylinder 52 is clamped between the side piece one 61 and the side piece two 62, then the material collecting rod 51 is sleeved from the middle part of the side piece one 61, the roll cylinder 52 and the side piece two 62, then the material collecting frame 5 is assembled on the arch-shaped frame 3, and the installation of the roll cylinder 52 is completed by clamping the side of the material collecting rod 51 through the rotating part. Conversely, when the winding of the cloth on the roll cylinder 52 is completed, the material collecting frame 5 is disassembled on the arch-shaped frame 3, then it is moved out from the middle part of the side piece one 61, the roll cylinder 52 and the side piece two 62, then the roll cylinder 52 with the cloth wound outside is taken out from between the side piece one 61 and the side piece two 62. By pulling the pull rod 623, the outer ring 621 is moved, and the side piece two 62 is moved synchronously, so that the roll cylinder 52 is taken out from between the side piece one 61 and the side piece two 62 to create space. The side piece one 61 is connected with the corresponding outer frame 34, so that the distance between the side piece one 61 and the side piece two 62 is always consistent with the distance between the adjacent two cutting knives 33. This not only ensures that the distance between the side piece one 61 and the side piece two 62 is consistent with the width of the cut cloth, but also ensures that the side piece one 61 and the side piece two 62 limit the side of the cloth when the roll cylinder 52 driven by the material collecting rod 51 winds the cloth, avoiding the shift of the cut cloth during winding, and improving the winding quality of the cloth.

[0028] The rotating part includes a rotating piece 53 rotationally connected with the material collecting frame 5. A moving rod 54 is slidably installed in the middle part of the rotating piece 53.

By pulling the moving rod 54 on the rotating piece 53, the rectangular block 542 at one end of the moving rod 54 is moved. When the rectangular block 542 is moved into the rectangular opening 521 at the end of the material collecting rod 51, the connection between the material collecting rod 51 and the rotating part is completed. When the material collecting rod 51 rotates to drive the roll cylinder 52 to rotate to wind the cut cloth, the motor is turned on to drive the sprocket set to rotate. When the sprocket set rotates, the rotating piece 53 rotates in the material collecting frame 5. When the rotating piece 53 rotates, the clamping strip 541 drives the moving rod 54 to rotate in the clamping groove 531. When the moving rod 54 rotates, the rectangular block 542 rotates. When the rectangular block 542 rotates, the material collecting rod 51 rotates, and finally the roll cylinder 52 winds the cloth.

One end of the shaft 47 is fixedly connected with the output end of the motor 46. Two corresponding cams 48 are fixedly installed on the shaft 47. The cam 48 is located above the circular arc plate 45. When one end of the cloth roll on the conveying part is pulled to the lower side of the cutting knife 33, the motor 46 is started to drive the shaft 47 to rotate. The shaft 47 drives the cams 48 on both sides to rotate synchronously. The cams 48 on both sides extrude the circular arc plate 45 intermittently during rotation. The circular arc plate 45 drives the inner frame 44 to slide downward in the rectangular groove 43 after being extruded. At this time, the plurality of slitting seats 4 and the connecting frames 42 synchronously follow the inner frame 44 to move downward, thereby giving space for the cloth to pass through the cutting knife 33.
