Description

Technical Field

[0001] The utility model relates to the technical field of white blank fabric production, in particular to a cutting and winding device for low-stretch white blank fabric. Background Technique

[0002] Blank fabric refers to the fabric made by spinning and weaving relevant fibers without dyeing and finishing. Blank fabric can be divided into rough blank and finished blank. The rough blank refers to the blank fabric directly taken off the loom without bleaching and dyeing treatment, while the finished blank refers to the blank fabric after bleaching and dyeing treatment. Low-stretch blank fabric refers to the fabric used for denim, work clothes, etc., generally with low stretchability.

[0003] After the fabric is produced, due to the requirements of processes and transportation, it needs to be cut and wound. However, at present, when cutting and winding the blank fabric on the market, most of them first transfer the fabric to the cutting machine after it is made, and then manually wind it after the cutting machine cuts the fabric as needed. However, this operation method not only has low work efficiency, but also causes the fabric to stack during winding, reducing the winding quality. Moreover, it is not convenient to fix the fabric during the cutting process, making it difficult to ensure the tension on the blank fabric during cutting and winding, resulting in uneven cutting of the blank fabric during cutting and reducing the cutting quality.

The cloth feeding roller 35, the cloth guiding roller 4 and the cloth winding roller 6 rotate synchronously through the transmission of the first pulley 31, the second pulley 33, the third pulley 34 and the belt 32.

[0031] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a rotating rod 91 is rotatably connected in the middle of the fixing frame 7. A rocker 92 is fixed on the end side of the rotating rod 91. Screw rods 93 are symmetrically sleeved on the outside of the rotating rod 91. A slider 94 is threadedly sleeved on the outside of the screw rod 93. A connecting rod 95 is hinged at the bottom of the slider 94. A connecting block 96 is hinged at the end side of the connecting rod 95. A connecting plate 97 is fixed at the bottom of the connecting block 96. A first spring 98 is fixed at the bottom of the connecting plate 97. The first spring 98 is fixedly connected with the pressing plate 9. Due to the elastic performance of the first spring 98, the pressing plate 9 always fits on the surface of the white blank fabric 5 when cutting the fabric, avoiding the white blank fabric 5 from wrinkling and stacking during cutting, thereby affecting the cutting effect.

[0032] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a support block 1001 is fixed on the side wall of the fixing frame 7. A second motor 1002 is fixed on the end side of the support block 1001. The output end of the second motor 1002 is fixedly connected with a lead screw 1003. A sliding block 1004 is threadedly sleeved on the outside of the lead screw 1003. The sliding block 1004 is fixedly connected with the self-driven cutting knife 10.

[0033] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a support frame 61 is fixed to the side wall of the base 1, an installation block 1101 is fixed to the side wall of the support frame 61, a sliding rod 1102 is slidably connected inside the installation block 1101, a slot 1103 is formed in the side wall of the sliding rod 1102, a support block 1104 is fixed to the end of the installation block 1101, a second spring 1105 is fixed to the end side of the support block 1104, a sliding rod 1106 is slidably embedded inside the support block 1104, a control rod 1107 is fixed to the end of the sliding rod 1106, an insertion block 1108 is fixed to the end of the sliding rod 1106, the insertion block 1108 is inserted into the slot 1103, the second spring 1105 is sleeved on the sliding rod 1102, the second spring 1105 is fixedly connected to the control rod 1107, and the insertion block 1108 is embedded into the slot 1103 to limit it, so as to prevent the sliding rod 1102 from sliding and thus affecting the stable use of the limiting plate 11. The specific model specifications of the first motor 3, the second motor 1002 and the self-driven cutting tool 10 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated.

[0034] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, during operation, the processed white blank fabric 5 is passed through between the cloth feeding roller 35 and the cloth guiding roller 4 and adhered to the outside of the cloth winding roller 6. Manually pull the control rod 1107 outwards to drive the sliding rod 1106 to slide outwards within the support block 1104 and stretch the spring, so that the insertion block 1108 at the end of the sliding rod 1106 disengages from the slot 1103 of the sliding rod 1102. Subsequently, move the sliding rod 1102 to slide horizontally within the mounting block 1101, thereby driving the limit plate 11 to slide along both sides of the cloth winding roller 6 and then fit against both ends of the white blank fabric 5 to limit it, so that the white blank fabric 5 will not be wound and stacked during winding, improving the winding quality; Start the first motor 3 to drive the cloth guiding roller 4 to rotate, and the first pulley 31 at its end will rotate immediately and drive the belt 32 to transmit power, so that the cloth feeding roller 35 at the end of the first pulley 31 and the cloth winding roller 6 at the end of the third pulley 34 rotate simultaneously to convey and wind the white blank fabric 5; After winding to the required thickness, it is necessary to cut the white blank fabric 5. During cutting, manually rotate the rocker 92 to drive the rotating rod 91 to rotate. When the rotating rod 91 rotates, the screw rod 93 outside it will rotate immediately, and the slider 94 sleeved on its external thread will slide horizontally immediately and drive the connecting rod 95 at the bottom to rotate. The connecting plate 97 installed at the bottom of the connecting rod 95 through the connecting block 96 will slide downwards immediately to drive the pressing plate 9 to fit against the surface of the white blank fabric 5, so that the white blank fabric 5 is stably pressed between the pressing plate 9 and the rotating roller 8. Start the second motor 1002 to drive the lead screw 1003 to rotate. When the lead screw 1003 rotates, the sliding block 1004 sleeved on its external thread will drive the self-driven cutting knife 10 at the bottom to slide horizontally along the surface of the white blank fabric 5 to cut the white blank fabric 5, so that the white blank fabric 5 can be tightened and cut, avoiding the slack of the blank fabric during cutting and thus affecting the cutting effect, making the cloth cutting uniform and improving the cutting quality.
