Description

Technical Field

[0001] The utility model belongs to the technical field of cloth spreading equipment, and in particular relates to a high-efficiency cloth spreading machine. Background Art

[0002] A cloth spreading machine is a machine that uses a mechanical method to flatten and cut rolled cloth. It is widely used in the modern clothing industry. When using the cloth spreading machine, the entire roll of cloth is pulled out to an appropriate length and laid flat before cutting it. It can be cut into various standard sizes of cloth as needed. A base on which the cloth is placed is provided on the table of the cloth spreading machine, and the base can be moved on the table to carry out the cloth spreading work.

By arranging center roller pressure rods 404 on both sides of the center roller 402, the cloth is input from one side of the center roller 402 and output from the other side of the center roller 402. The center roller pressure rods 404 press the cloth against the center roller 402 at the input side and the output side respectively. At the same time, the center roller pressure rods 404 can also rotate, so that when the center roller 402 rotates, it can drive the cloth to move toward the cutting mechanism 5, thereby reducing the slippage between the cloth and the center roller 402, effectively preventing the center roller 402 from idling, and improving the guiding effect of the main roller 4 on the cloth; at the same time, an anti-inward roll roller 405 is also arranged on the side of the center roller 402 close to the cutting mechanism 5 (i.e., the output side). After the cloth is output from between the center roller 402 and the center roller pressure rod 404 on the output side, it is guided by the anti-inward roll roller 405 and then output, thereby effectively preventing the cloth from being wound around the center roller 402.

When in use, as the height of the cloth rises, the tool guide rail 52 and the guide plate 54 rise along the lifting guide rail 42, so that the distance between the cutting tool 51 and the top layer of cloth remains fixed, so that when the cloth is cut, the cutting tool 51 will not cause damage to the bottom layer of cloth due to changes in the thickness of the cloth stack.

[0044] In this embodiment, if Figure 2 and Figure 3 As shown, both sides of the cloth placing plate 1 can be slidably mounted with a first mounting plate 31, a lifting rail 42 is mounted on the first mounting plate 31, a slidable first slider 43 is arranged on the lifting rail 42, a second mounting plate 41 is arranged on the first slider 43, and the main roller 4, the tool guide rail 52 and the two ends of the guide plate 54 are mounted on the second mounting plate 41. According to the thickness of the cloth, after each layer of cloth is laid flat, the first slider 43 rises to a corresponding height along the lifting rail 42, thereby ensuring that the cutting tool 51 always maintains a constant distance from the top layer of cloth.

[0045] In this embodiment, the second mounting plate 41 is mounted on the first sliding block 43 .

[0046] In this embodiment, if Figure 6 As shown, a positioning rod 55 is also installed between the two second mounting plates 41 , and a plurality of elastic sheets 56 are installed in parallel on the positioning rod 55 .

Both the first spreading curved pipe 32 and the second spreading curved pipe 36 are arc-shaped pipes, and the two ends of the arc-shaped pipes are rotatably mounted on the first mounting plate 31. When the arc-shaped pipes rotate, the cloth will be spread from the middle to both sides, which can effectively avoid the generation of wrinkles. The pressing roller 33 is arranged above the straight tube 34, and the pressing roller 33 and the straight tube 34 are arranged adjacent to each other. The material head passes between the pressing roller 33 and the straight tube 34 from above the first bent tube 32. The pressing roller 33 presses the fabric tightly on the straight tube 34.
