[0028] like Figure 1 , Figure 2 and Figure 4 As shown, an embodiment of the utility model proposes a cloth cutting device for tent production, including a cutting machine tool, which includes a support frame 1, two front side plates 2 are fixedly installed on the front side of the support frame 1, a screw rod 3 is rotatably installed on the front side plate 2, a lifting plate 4 is threadedly installed on the outer side of the screw rod 3, and two inclined plates 5 are fixedly installed on one side of the lifting plate 4, a plurality of circular shafts 6 are fixedly installed on the front and rear sides of the inclined plate 5, a rotating plate 7 with an inclined arrangement is rotatably installed on the outer side of the circular shaft 6, a friction cylinder 8 is fixedly installed on the bottom of the rotating plate 7, a plurality of extension plates 9 are fixedly installed on the front and rear sides of the inclined plate 5, a bent rod 10 is fixedly installed on the top of the extension plate 9, the rotating plate 7 is slidably sleeved on the outer side of the corresponding bent rod 10, and a same limit spring 11 is fixedly installed between the top of the extension plate 9 and the bottom of the corresponding rotating plate 7, and the limit spring 11 is wound around the outer side of the corresponding bent rod 10.

[0029] like Figure 5 As shown, two square grooves 12 are provided on the top of the lifting plate 4, and a pressure plate 13 is vertically slidably installed in the square groove 12. A plurality of pressure springs 14 are fixedly installed between the top of the pressure plate 13 and the corresponding inner wall of the top of the square groove 12. The cooperation between the pressure spring 14 and the pressure plate 13 enhances the stabilizing effect of pressing the cloth.

[0030] like Figure 1 and Figure 3 As shown, a driving motor 15 is fixedly installed at the bottom of the front side plate 2 on the right side, and the output shaft of the driving motor 15 is fixedly connected to the corresponding screw rod 3. A pulley 16 is provided on the outer fixed sleeve of the screw rod 3. The same belt 17 is installed on the two pulleys 16 for transmission. The lifting plate 4 is driven by the screw rod 3 to perform vertical movement to press and fix the cloth.

[0031] like Figure 1 As shown, two rear side plates are fixedly installed on the rear side of the support frame 1, and a guide plate 18 is fixedly installed on the top of the rear side plate. The lifting plate 4 is slidably sleeved on the outer side of the corresponding guide plate 18 to guide the movement of the lifting plate 4.

[0032] like Figure 1 and Figure 3 As shown, a conveyor belt 19 is arranged in the support frame 1, and a support plate 20 is fixedly installed in the support frame 1. The top of the support plate 20 is movably abutted against the inner wall of the conveyor belt 19, and the function of loading and unloading the cloth is realized through the movement of the conveyor belt 19. The support plate 20 supports the conveyor belt 19 to prevent the conveyor belt 19 from being deformed when subjected to the pressure of the lifting plate 4, thereby affecting the stability of pressing the cloth.

[0033] like Figure 1 As shown, the cutting machine tool further comprises a moving mechanism 21 , an electrical cabinet 22 is arranged on the top of the moving mechanism 21 , a lifting and rotating mechanism 23 is arranged on one side of the electrical cabinet 22 , and a cutting knife is arranged at the bottom end of the lifting and rotating mechanism 23 .

[0034] It should be noted that the cutting machine is a CNC cutting machine, which is a machine that uses computer numerical control technology to perform cutting operations. It can accurately control the tool to cut the material according to the pre-input CNC program to achieve a high-precision and high-efficiency production process. The crossbeam moves along the lateral track of the cutting machine frame to cover the entire cutting area on the workbench.

[0035] Furthermore, the moving mechanism 21 drives the electrical cabinet 22 to move in the X or Y axis direction to cover the entire cutting area on the top of the cutting machine. The lifting and rotating mechanism 23 enables the cutting head to move up and down and has a rotation function to perform cutting of complex contours. These functions are usually controlled by a CNC system and adjusted according to a preset cutting path to cut out fabric of the required shape of the tent.

[0036] Working principle: The cloth is transported to the center of the cloth and coincides with the center of the cutting machine by the conveyor belt 19. At this time, the four corners of the cloth are respectively located directly below the corresponding inclined plates 5. The drive motor 15 is started. The output shaft of the drive motor 15 drives the two screws 3 to rotate synchronously through the cooperation of the pulley 16 and the belt 17, thereby driving the two lifting plates 4 to move downward until the friction cylinder 8 abuts against the cloth. During the descent of the lifting plates 4, the bottom of the rotating plate 7 abuts against the cloth and cannot move downward, so that it swings upward with the circular shaft 6 as the axis, thereby driving the top of the rotating plate 7 to swing downward, thereby compressing the limit spring 11, pressing The contracted limit spring 11 provides resistance to the upward swinging of the bottom of the rotating plate 7, so that friction is generated between the friction cylinder 8 and the cloth. The direction of the friction is the same as the horizontal direction of the movement of the friction cylinder 8, thereby driving the four corners of the cloth to move gradually outward synchronously, so that the cloth gradually stretches on the diagonal, and the wrinkles and creases on the cloth gradually decrease or disappear completely. Afterwards, the pressing plate 13 abuts against the cloth, and the lifting plate 4 continues to move downward, thereby driving the pressing plate 13 to move upward relative to the lifting plate 4 to compress multiple pressure springs 14. The cooperation between the pressure springs 14 and the pressing plate 13 enhances the stable pressing effect on the cloth.

[0037] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
