[0040] See also Figure 1 to Figure 6 , a cloth cutting device and a men's trousers cutting method for producing bamboo cotton men's trousers of the present invention, compared with the first embodiment, this embodiment also includes: a material pressing assembly 6 includes a downward pressing displacement frame 61 arranged on the side guide rail of the cutting table 1 by meshing transmission; the front end of the displacement block of the downward pressing displacement frame 61 is fixedly installed with a second mounting frame 62 by bolts; a driving member with an adjusting function is arranged on the inner side of the second mounting frame 62, and a downward pressing plate 63 is fixedly installed on the bottom of the driving member by bolts; a material pulling displacement frame 64 is arranged on the side guide rail of the cutting table 1 by meshing transmission; a second adjusting cylinder 65 with an adjusting function is fixedly installed on the lateral displacement block of the material pulling displacement frame 64 by bolts; a push plate 66 is fixedly installed at the rear end of the piston rod of the second adjusting cylinder 65, and the rear side of the push plate 66 is fixedly connected to the connecting rod on the middle side of the clamping head 67.

[0041] Based on the above-mentioned working principle of a cloth cutting device and a men's trousers cutting method for producing bamboo cotton men's trousers, the following are the working principles:

[0042] First, when using the device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation, and provide air source for the first regulating cylinder 572, the airflow collar 584, the pressure control valve 5762 and the second regulating cylinder 65 related equipment through the external pipeline;

[0043] Second, the staff places the bamboo cotton cloth to be cut on the material rack 7, and then drives the second adjusting cylinder 65 and the clamping head 67 to adjust the horizontal displacement through the material pulling displacement rack 64 through the guide rail on the side of the cutting bed 1, and then the staff pulls the bamboo cotton cloth on the material rack 7 out of the cloth head, and at this time controls the second adjusting cylinder 65 and the clamping head 67 to be close to the bamboo cotton cloth head, and provides the second adjusting cylinder 65 with an air source through an external air pipe so that it pushes the push plate 66 to squeeze the side connecting rod in the clamping head 67, where the clamping head 67 is adjusted and squeezed to open and close the clamping plate and clamp the bamboo cotton cloth head, and then drives the clamping head 67 and the bamboo cotton cloth head to be pulled back and forth horizontally on the top of the cutting bed 1 through the material pulling displacement rack 64, so that a plurality of bamboo cotton cloths are stacked layer by layer and laid flat on the cutting bed 1, and according to the thickness of the flattened cloth, the driving member in the second mounting frame 62 is controlled to drive the lower pressing plate 63 to press and fix the cloth layer on the top of the cutting bed 1;

[0044] Third, according to the size data of men's trousers, the inclination of the front upper crotch of men's trousers is set to be 1CM larger than the standard value, and the looseness of the front and rear upper crotch is controlled between 0.14 and 0.16 according to the inclination angle data M of the hip circumference of men's trousers. At the same time, according to the processing requirements of men's trousers, the inclination angle data M of the hip circumference is set to 14 degrees to 16 degrees, 10 degrees to 15 degrees, and 5 degrees to 10 degrees, respectively, so that close-fitting loose men's trousers, normal loose men's trousers and loose loose men's trousers can be cut respectively; according to the above data, the layout setting is performed after reserving the processing width, and the reserved width path and the standard cutting path are enlarged in equal proportion;

[0045] Fourth, then adjust the spacing data between the marking component 57 and the cutting knife of the cutting component 4. Here, the stepping motor 51 drives the gear plate 53 and the first driven gear 55 through the driving gear 52 to engage and transmit. Here, the electromagnetic sleeve 56 in the first driven gear 55 is energized to drive its internal rotating shaft and the marking component 57 to rotate accordingly, thereby adjusting the deviation angle of the first mounting frame 571 and the pressure rod component 576. At this time, the second driven gear 585 rotates with the gear plate 53 to drive its internal connecting rod 583 to rotate accordingly. Here, the connecting rod 583 and the speed sensor 582 are used to detect the deviation angle of the marking component 57, and then the gear group housing 573 is pushed by the first adjusting cylinder 572 to adjust the displacement, so that the marking rod 5766 is on the standard cutting path of men's trousers, and the cutting knife of the cutting component 4 is on the reserved width cutting path of men's trousers. Since the gear plate 53 adjusts the angle of the cutting knife during rotation Adjustment, at this time, the electromagnetic sleeve 56 is energized to avoid affecting the angle of the marking component 57, and the rotation of the gear plate 53 also drives the spatial position of the first locator 54 to be adjusted, and the distance between the first locator 54 and the second locator 5764 changes. Here, the micro motor 574 drives the internal gear of the gear set housing 573 and the adsorbent 575 to engage and transmit, so that the adsorbent 575 and the sleeve ring 5763 and the second locator 5764 rotate synchronously, and the adsorbent 575 and the gear plate 53 rotate synchronously and cooperate with the first adjustment cylinder 572, so that the distance between the first locator 54 and the second locator 5764 is maintained at the minimum error range value. Here, the detection data between the first locator 54 and the second locator 5764 is calculated by the single body controller 5765, so that the marking rod 5766 and the cutting point of the cutting knife are synchronously adjusted;

[0046] Fifth, the marking component 57 is driven to perform the knife test step through the adjustment action of the cutting displacement frame 2. At this time, the marking rod 5766 contacts the upper surface of the top cloth layer of the cutting bed 1. Here, the top piston plate of the marking rod 5766 slides inside the hollow shaft 5761, and the internal air pressure of the hollow shaft 5761 is used to provide a proper downward pressure action for the marking rod 5766. Here, the cutting knife in the cutting component 4 is controlled to be at the initial point of the workstation without cutting the bamboo cotton cloth layer. Then, the visual camera in the visual component 59 collects the displacement path formed by the squeezing of the marking rod 5766 and the top cloth layer of the cutting bed 1 in real time, and the data collected by the visual component 59 is calculated through the control terminal, and the path correctness is detected;

[0047] Sixth, the top side cloth layer of the cutting bed 1 is cut by the cutting displacement frame 2 and the cutting assembly 4 on the cutting frame 3, and the cutting path of the cutting assembly 4 is monitored by repeating the knife testing process of the marking assembly 57; at this time, the adjustment angle of the cutting knife and the gear plate 53 in the cutting assembly 4 is monitored in real time by the detection assembly 58, and the detection assembly 58 blows away the cloth waste on the cutting knife path, and then removes the cut cloth to complete the cutting work.

[0048] The present invention provides a cloth cutting device and a method for cutting bamboo cotton men's trousers through improvements. By arranging an adjustment component 5 on the top of a cutting frame 3, a transmission action between a stepping motor 51 and a gear plate 53 is performed, and with the cooperation of a marking component 57 and a visual component 59, a marking rod 5766 is synchronously controlled to complete synchronous adjustment with the cutting point of the cutting knife, thereby improving the accuracy of the marking component 57 test knife path data detection and also improving the accuracy of cloth cutting; by arranging a pressing component 6 on the side guide rail of a cutting bed 1, semi-automatic laying and pressing of bamboo cotton cloth is realized, thereby improving the cutting efficiency.
