Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0026] Reference Figure 1-3 A cloth roll cutting machine comprises a carrying table 1, a supporting mechanism 2 is fixedly connected to the rear end of the upper surface of the carrying table 1, an encoder 3 is installed at the front end of the supporting mechanism 2, a limiting mechanism 4 is fixedly connected to the middle of the upper surface of the carrying table 1, a cutting device 7 is slidably connected inside the limiting mechanism 4, a pressing block 8 is fixedly connected to the upper surface of the carrying table 1 and located on the side of the limiting mechanism 4 away from the supporting mechanism 2, a fixing mechanism 6 is fixedly connected to both sides of the pressing block 8 and located on the upper surface of the carrying table 1, a magnetic attraction mechanism 5 is installed below the fixing mechanism 6, and the magnetic attraction mechanism 5 is located between the fixing mechanism 6 and the pressing block 8, a controller 9 is installed on the upper surface of the carrying table 1, and the controller 9 is electrically connected to the encoder 3, the magnetic attraction mechanism 5, and the fixing mechanism 6.

[0027] Reference Figure 1-3 The support mechanism 2 includes two support plates 201, a cloth roll 202 is rotatably connected to one side near the upper end of the support plate 201, a connecting plate 203 is fixedly connected to the front end of the support plate 201, a cloth pressing roller 204 is rotatably connected to the lower end of the connecting plate 203 near the support plate 201, a support plate 205 is fixedly connected to the lower end of the connecting plate 203 away from the support plate 201, and a connecting plate 203 is fixedly connected to the upper end of the connecting plate 203 away from the support plate 201. First, the required cloth length needs to be input on the controller 9, and then the cloth is dragged from the cloth roll 202 to bypass the cloth pressing roller 204, and then dragged forward from the position above the support plate 205 and below the encoder 3 to ensure that the cloth located above the support plate 205 and below the encoder 3 is in contact with the upper surface of the support plate 205, and the preparation operation is completed.

[0028] Reference Figure 1-3 The limiting mechanism 4 includes a limiting plate 401, which is slidably connected to the upper surface of the load-bearing table 1, and L-shaped plates 402 are fixedly connected on both sides of the limiting plate 401. The L-shaped plates 402 are slidably connected to the positions on both sides of the load-bearing table 1, and bolts are threadedly connected at the lower ends of the L-shaped plates 402. The limiting plate 401 is slid forward and backward to a proper position, and the limiting mechanism 4 is fixed to the upper end of the load-bearing table 1 through the bolts at the lower end of the L-shaped plate 402, and the fixing of the limiting mechanism 4 is completed. When in use, the cloth needs to be covered above the limiting plate 401.

[0029] Reference Figure 1-3The magnetic attraction mechanism 5 includes a support column 501, which is fixedly connected to both sides of the upper surface of the support table 1. A connecting plate 502 is fixedly connected to the upper end of the support column 501, and two first electromagnetic blocks 503 are fixedly connected to both sides of the lower surface of the connecting plate 502 and located between the support columns 501. The cloth passes between the fixing mechanism 6 and the lower pressing block 8. When the cloth dragging distance is less than the set length, the first electromagnetic block 503 is energized, and the first electromagnetic block 503 generates a magnetic field to attract the fixing mechanism 6 to move upward, so that a distance is generated between the fixing mechanism 6 and the lower pressing block 8, which can be used to drag the cloth to move, thereby ensuring the passage of the cloth.

[0030] Reference Figure 1-3 The fixing mechanism 6 includes a spring 601, which is sleeved on the side of the support column 501, and the lower end of the spring 601 is fixedly connected to the upper surface of the load-bearing table 1. The upper end of the spring 601 is fixedly connected to a fixing plate 602, and an upper pressure plate 603 is fixedly connected to a side close to the fixing plate 602. The upper surface of the upper pressure plate 603 is fixedly connected to the second electromagnetic block 604 at a corresponding position above and below the second electromagnetic block 604. The upper surface of the upper pressure plate 603 is stepped, and the upper surface of the lower pressure block 8 is complementary in shape to the lower surface of the upper pressure plate 603. When the dragging distance of the cloth is less than the set length, the first electromagnetic block 503 and the second electromagnetic block 604 are both energized, and the first electromagnetic block 503 and the second electromagnetic block 604 attract each other. When the dragging distance is equal to the set length, the first electromagnetic block 503 and the second electromagnetic block 604 stop being energized, so that the fixing mechanism 6 moves downward under the action of the spring 601, driving the upper pressure plate 603 to press down on the lower pressure block 8, clamping the cloth between the upper pressure plate 603 and the lower pressure block 8, thereby realizing the positioning of the cloth, and then the cloth can be cut by the cutting device 7.

[0031] Reference Figure 1-3 The horizontal height of the upper surface of the support plate 205 is greater than the horizontal height of the lower end of the cloth pressing roller 204, and the encoder 3 is installed on the connecting plate 203. The horizontal height of the upper surface of the support plate 205 is greater than the horizontal height of the lower end of the cloth pressing roller 204, which can make the surface of the cloth stick to the upper surface of the support plate 205. The encoder 3 calculates the movement distance by detecting the pattern of the surface of the cloth on the upper surface of the support plate 205, thereby determining the interception length.

[0032] Working principle: First, input the required cloth length on the controller 9, then drag the cloth from the cloth roll roller 202 to bypass the cloth pressing roller 204, and then drag it forward from the position above the support plate 205 and below the encoder 3 to ensure that the cloth above the support plate 205 and below the encoder 3 fits the upper surface of the support plate 205, and the preparation operation is completed. Slide the limit plate 401 forward and backward to the appropriate position, and fix the limit mechanism 4 to the upper end of the load table 1 through the bolts at the lower end of the L-shaped plate 402, and the limit mechanism 4 is fixed. When using, the cloth needs to be covered above the limit plate 401;

[0033] The cloth passes between the fixing mechanism 6 and the lower pressing block 8. When the cloth dragging distance is less than the set length, the first electromagnetic block 503 is energized, and the first electromagnetic block 503 generates a magnetic field, attracting the fixing mechanism 6 to move upward, so that a distance is generated between the fixing mechanism 6 and the lower pressing block 8, which can be used to drag the cloth to move, thereby ensuring the passage of the cloth. When the cloth dragging distance is less than the set length, the first electromagnetic block 503 and the second electromagnetic block 604 are both energized, and the first electromagnetic block 503 and the second electromagnetic block 604 attract each other. When the dragging distance is equal to the set length, the first electromagnetic block 503 and the second electromagnetic block 604 stop energizing, so that the fixing mechanism 6 moves downward under the action of the spring 601, driving the upper pressing plate 603 to press down on the lower pressing block 8, clamping the cloth between the upper pressing plate 603 and the lower pressing block 8, thereby realizing the positioning of the cloth, and then the cloth can be cut by the cutting device 7;

[0034] The horizontal height of the upper surface of the support plate 205 is greater than the horizontal height of the lower end of the cloth pressing roller 204, which can cause the cloth surface to fit the upper surface of the support plate 205. The encoder 3 calculates the movement distance by detecting the pattern of the cloth surface on the upper surface of the support plate 205, thereby determining the interception length.

[0035] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
