[0002] When clothing is being produced, it is usually necessary to cut the fabric into corresponding sizes in order to facilitate subsequent centralized processing. For example, in the fabric processing of medical clothing, the inventor first transfers the fabric to a large-diameter winding device through a conveying device and a tensioning device, and winds it into a roll of corresponding thickness through the winding device. Then, the fabric is cut by a cutting tool and pulled onto a carrier for stacking and stacking for subsequent processing. However, when cutting the fabric, it is necessary to ensure the flatness of the fabric. If the flatness of the fabric is not enough at this time, the size and shape of the fabric after cutting will be different, which will cause the quality of the fabric after cutting to be insufficient in subsequent sewing and other processing, thereby increasing the production cost.

[0024] See also Figure 1-5 The utility model discloses a cloth cutting device, including a winding device and a platform 1 arranged on one side of the winding device, a moving device is installed on the platform 1, and the moving device can move along the X, Y and Z axis directions of the platform 1. A processing mechanism 5 is installed at the moving end of the moving device, and the processing mechanism 5 is used to pull the cloth.

[0025] In one embodiment, the processing mechanism 5 includes a clamping device for clamping the cloth and a leveling roller 7 installed at the bottom of the clamping device. Positioning devices are provided at both ends of the platform 1, and the positioning devices are used to position the two ends of the cloth on the platform 1. A stacking device may be provided on the platform 1, and the stacking device includes a plurality of stacking rollers 10 rotatably installed at both ends of the platform 1 and distributed up and down. At the same time, the stacking rollers 10 are detachably arranged on the platform 1, and the cloth passes around the stacking rollers 10 located at both ends of the platform 1 in an S shape, so that the cloth is stacked in an S shape.

[0026] In a specific implementation, when it is necessary to pull the cloth, the clamping device is controlled to clamp the cloth, and then the staff winds the cloth on the stacking roller 10. After each stacking roller 10 is wound, the stacking roller 10 is immediately installed above the cloth. As the processing mechanism 5 clamps the cloth and moves it, the staff immediately wraps the cloth moved to both ends of the platform 1 around multiple stacking rollers 10 in an S shape, thereby completing the stacking. In the process of pulling and stacking the cloth, the clamping device will move with the cloth, and the leveling roller 7 will contact the stacked cloth under the clamping device during the movement, and cooperate with the moving device to make the processing mechanism 5 move up and down, so that the cloth can be flattened during the pulling and stacking process, so that the cloth stack is flat, which is convenient for subsequent cutting.

[0027] In one embodiment, the moving device includes a linear module B2 installed on the side of the platform 1, a linear module C3 installed on the moving end of the linear module B2, and a lifting mechanism 4 installed on the moving end of the linear module C3, and the processing mechanism 5 is installed on the lifting moving end of the lifting mechanism 4. The lifting mechanism 4 can use hydraulic principles to control the lifting movement of the processing mechanism 5.

[0028] In a specific implementation, the linear module B2 is used to drive the linear module C3 to move along the Z axis of the platform 1, the linear module C3 is used to drive the lifting mechanism 4 to move along the X axis of the platform 1, and the lifting mechanism 4 is used to drive the processing mechanism 5 to move up and down.

[0029] In one embodiment, the clamping device includes a mounting platform 51 installed on the moving end of the mobile device, a laser rangefinder 52 installed on the mounting platform 51, a clamping frame 53 rotatably installed on one end of the mounting platform 51, a motor 54 arranged on the mounting platform 51, and a traction clamp 55 arranged at the other end of the clamping frame 53. The laser rangefinder 52 is used to measure the distance between the traction clamp 55 and the cloth, the motor 54 is used to drive the clamping frame 53 to rotate, and the clamping frame 53 is provided with a power device that drives the traction clamp 55 to clamp or release.

[0030] In a specific implementation, the motor 54 can drive the clamping frame 53 to change the clamping and traction angle, and the power device is used to control the traction clamp 55 to clamp or release the cloth, thereby traction of the cloth. Therefore, when the lifting mechanism 4 mentioned above is in use, it can control the clamping frame 53 to adjust in multiple directions on the platform 1, and can adjust the corresponding clamping and traction angle to clamp the cloth that needs to be pulled into an S shape and stacked. In addition, a bolt member 6 is installed on the clamping frame 53, and the bolt member 6 is used to fix the traction clamp 55, so that the traction clamp 55 has the function of being detachable and maintainable.

[0031] In one embodiment, both sides of the leveling roller 7 are provided with spiral expansion lines extending toward one end away from the center of the leveling roller 7. The expansion lines are used to expand the two sides of the cloth in contact with the leveling roller 7 outward when the leveling roller 7 rotates, so as to reduce the occurrence of cloth wrinkles. In addition, the lines on the leveling roller 7 are unidirectional, so the leveling roller 7 only contacts the cloth when it moves in one direction, and the leveling roller 7 needs to be lifted when it moves in another direction so that it does not contact the bottom cloth.

[0032] In one embodiment, the stacking device includes a support 8 installed on both sides of the platform 1, a scissor-type bracket 9 hingedly installed on the support 8, and a C-type positioning frame 11 installed at each cross-connection point in the middle of the scissor-type bracket 9. Locking plates 12 are installed at both ends of the stacking roller 10, and the locking plates 12 are detachably installed on the C-type positioning frame 11, wherein the scissor-type bracket 9 is used to adjust the relative spacing of each C-type positioning frame 11, and a braking device for limiting the scissor-type bracket 9 is also provided on the support 8.

[0033] In specific implementation, when in use, the staff manually adjusts the scissor-type bracket 9 to fold or unfold it, so that the spacing between the multiple C-type positioning frames 11 is reduced or increased, and the stacking roller 10 is connected to the C-type positioning frame 11 through the locking plate 12, so that the multiple stacking rollers 10 can adjust the spacing between each other to facilitate wrapping of fabrics of different layers of thickness. In actual circumstances, a pin can be installed on the locking plate 12, and the pin extends downward and is inserted into the locking plate 12, so that the structure of the stacking roller 10 when wrapping the fabric is very stable. After the pin is removed, the stacking roller 10 can be rotated and adjusted to return to its position, thereby facilitating the subsequent pressing of the fabric.

[0034] The braking device mentioned above can be a long bolt vertically threadedly installed on the support 8, and the long bolt can be spirally lifted and lowered on the support 8. When the scissor-type bracket 9 is folded or unfolded at different angles, it is only necessary to adjust the height of the long bolt and make one end of the long bolt contact the bottom end of the scissor-type bracket 9 to brake the scissor-type bracket 9, so that the stacking roller 10 is adjusted to the corresponding height and then limited.
