Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0020] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components.

[0022] Example 1:

[0023] like Figure 1 -2, a material cutting device includes a base plate 1, with side frames 2 on both sides of the base plate 1, and a feed roller 3, a cutting roller 5, a flat knife rod 8, and a discharge roller 10 arranged in sequence between the two side frames 2. The cutting roller 5 is located between the feed roller 3 and the discharge roller 10, and the flat knife rod 8 is located between the discharge roller 10 and the cutting roller 5. The cutting roller 5 is provided with a plurality of circular blades 6, and the flat knife rod 8 is provided with a plurality of flat knives 9, and the flat knives 9 correspond one to one with the circular blades 6.

[0024] The circular blade 6 is a single circular blade with a double-sided edge. A shearing roller can also be provided below the cutting roller 5, and a circular blade 6 is also provided on the shearing roller. The two circular blades 6 on the shearing roller and the cutting roller 5 are both single-sided shearing circular blades. The material is cut by the shearing action of the two circular blades 6, which is mainly suitable for warp and weft woven materials.

[0025] The material cutting device of this embodiment uses a circular knife to cut the material before winding, and the blade 95 completely divides the material into material strips to avoid uncut material strips. There is no need to cut the material roll after winding.

[0026] A guide roller 4 is provided between the feed roller 3 and the cutter roller 5 ; the guide roller 4 is used to guide the movement of the material and to tension the material between the cutter roller 5 and the feed roller 3 so that the circular knife on the cutter roller 5 can cut the material.

[0027] There are two feed rollers 3 and two discharging rollers 10, and the material is fed from between the two feed rollers 3 and discharged from between the two discharging rollers 10; a single feed roller 3 and a discharging roller 10 mainly rely on friction for feeding and discharging. When the material tension is small, slipping is likely to occur, making it impossible to feed and discharge the material. The cooperation of two feed rollers 3 or two discharging rollers 10 can effectively maintain friction through extrusion to avoid slipping.

[0028] A motor 7 is provided under the base plate 1, and the output shaft of the motor 7 and the cutting roller 5 are both provided with pulleys, and the two pulleys are connected by a belt; the motor 7 drives the pulley to rotate, and transmits power to the cutting roller 5 through the belt, so that the cutting roller 5 drives the circular blade 6 to rotate, thereby completing the cutting of the material.

[0029] like Figure 3 As shown, the flat knife 9 includes a clamping block 91, a clamping plate 92, a pressure block 93 and a blade 95. The clamping block 91 cooperates with the clamping plate 92 to clamp the flat knife rod 8. One end of the clamping plate 92 is hinged to the clamping block 91, and the other end of the clamping plate 92 is fixed to the clamping block 91 by a screw. The clamping block 91 is provided with a mounting groove on one side of the clamping plate 92, and the pressure block 93 presses the blade 95 in the mounting groove through a bolt 94, and the cutting edge of the blade 95 faces the circular blade 6; when fixing the blade 95, the bolt 94 is rotated so that the pressure block 93 presses the blade 95 into the mounting groove, and the upper end of the blade 95 is exposed from the pressure block 93 to cut the material. When the flat knife 9 is fixed to the flat knife rod 8, it is only necessary to rotate the clamping plate 92 to clamp the clamping block 91 on the flat knife rod 8, and then lock the clamping block 91 and the clamping plate 92 by screws, so that the clamping plate 92 and the clamping block 91 cooperate to be firmly fixed on the flat knife rod 8.

[0030] Working principle: The material passes between the two feed rollers 3 and is squeezed and fed by the two feed rollers 3. After being guided and tensioned by the top of the guide roller 4, it enters the bottom of the cutting roller 5 and is cut by the circular blade 6 to form multiple material strips. Then the material strips pass around the top of the flat knife rod 8, and the flat knife 9 cuts off the material strips that are still connected. Finally, the material strips are squeezed out through the two discharge rollers 10.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
