Description

Technical Field

[0001] The invention relates to the technical field of cloth cutting, in particular to a cloth cutting device for producing police raincoats. Background Art

[0002] Police raincoats have some unique features and requirements to ensure that police can maintain mobility, comfort and professionalism in all kinds of adverse weather conditions. In the production of police raincoats, fabric cutting is a key link. The fabric of the raincoat is cut into a suitable size by a cutting device to facilitate the subsequent processing of the raincoat. Most of the current cutting devices flatten the fabric and cut it directly with a cutting knife during transportation. However, the fabric on both sides of the blade is not pressed tightly during cutting, which leads to deviations when the fabric is cut due to the elasticity of the fabric itself, affecting the accuracy of the cut fabric size. At the same time, the edges of the cut fabric are not smooth, which may produce burrs, derailment or uneven cuts, affecting the appearance and quality of the raincoat, and even affecting the stability of sewing. Summary of the invention

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] First embodiment

[0029] The fabric used in raincoat production usually arrives at the production workshop in the form of rolls. The fabric rolls need to be spread out and ensure that the fabric is flat and wrinkle-free. Then the fabric is cut to a suitable size for processing. Since the prior art often transports the flattened fabric to the cutting position for cutting, the lack of compression of the fabric on both sides of the cutting knife 42 can easily lead to deviations in the cut fabric, affecting the accuracy of the cut fabric size. In order to prevent the fabric from being mechanically stretched or deformed during the cutting process, which affects the accuracy of the cut fabric size, and to ensure the quality of cutting, refer to Figure 1 - Figure 5 The present embodiment provides a cloth cutting device for producing police raincoats, which is composed of a processing table 1, a cutting table 2, a conveyor belt 3 and a cutting mechanism 4. The cutting table 2 is fixedly installed on one end of the top of the processing table 1, and the conveyor belt is fixedly installed on one end of the cutting table 2 to transport the cut cloth to the next raincoat production process.

[0030] A cutting mechanism 4 for cutting the raincoat fabric after rolling it up and flattening it is provided on the processing table 1. The cutting mechanism 4 includes a support frame 41 provided on the cutting table 2, and a cutting knife 42 installed on the inner side of the support frame 41. A servo cylinder 43 is fixedly installed on the top of the support frame 41. The output shaft of the servo cylinder 43 is detachably provided with a driving cross plate 44. The output end of the servo cylinder 43 pushes the driving cross plate 44 downward to move, and the driving cross plate 44 drives the cutting knife 42 downward to cut the fabric. The cutting knife 42 is detachably fixed on the driving cross plate 44, which helps to regularly disassemble and maintain the cutting knife 42 to prevent the cutting knife 42 from affecting the cutting effect due to the blade not being sharp enough.

[0031] In order to effectively fix the fabric on both sides of the cutting mouth, prevent the fabric from moving during the cutting process, and ensure the accuracy of fabric cutting, a flattening component 45 for pressing and flattening the raincoat fabric during cutting is arranged at the bottom of the driving cross plate 44. The flattening component 45 includes a flattening roller group 451 arranged at one side of the bottom of the support frame 41 and fixed to the cutting table 2. The fabric entering the cutting seat 452 first passes through the flattening roller group 451 to further remove wrinkles on the fabric, and a cutting seat 452 arranged at one end of the conveyor belt 3 and located at the bottom of the support frame 41. Active pressing rollers 453 are respectively arranged on both sides of the cutting seat 452. Both ends of the movable pressing roller 453 are respectively provided with inclined seats 454 fixed with the cutting seat 452, and limiting rollers 455 are respectively rotatably arranged on the two inclined seats 454. Both ends of the movable pressing roller 453 are respectively fixed with connecting shafts fixed with the two limiting rollers 455. When the limiting roller 455 moves toward the direction of the cutting knife 42, the limiting roller 455 rolls downward on the inclined seat 454, driving the movable pressing roller 453 to move horizontally and downward at the same time, so that the movable pressing roller 453 rolls on the cloth for a distance and then presses it, which can smooth out the wrinkles on the cloth again and press the cloth on the side of the blade.

[0032] A transmission assembly 456 for simultaneously pushing the two movable pressure rollers 453 to move toward the middle is provided on the top of the cutting seat 452, and the transmission assembly 456 includes a threaded horizontal shaft 4561 respectively provided at the two ends of the top of the two movable pressure rollers 453, and the two ends of the threaded horizontal shaft 4561 are rotatably connected to the support frame 41 through bearing seats, one end of the threaded horizontal shaft 4561 is threadedly connected with a threaded seat 4562, and a return spring is fixedly provided at the bottom of the threaded seat 4562, and the initial position of the return spring is set to a compressed state. When the movable pressure roller 453 moves, the return spring restores the elastic deformation to push the movable pressure roller 453 to move downward, and a limit seat 4563 is fixed at the bottom of the return spring, which rotates with the connecting shaft through a bearing, and a transmission gear 4564 is fixed at the other end of the threaded horizontal shaft 4561, and a driving rack 4565 fixed to the bottom of the driving horizontal plate 44 is provided at the top of the transmission gear 4564.

[0033] When the driving cross plate 44 moves downward, it pushes the driving rack 4565 to move downward, and the driving rack 4565 drives the transmission gear 4564 to rotate, and the transmission gear 4564 drives the threaded cross shaft 4561 at its axis to rotate, and the threaded cross shaft 4561 drives the threaded seat 4562 to move in the direction of the cutting knife 42, and the threaded seat 4562 drives the reset spring and the limit seat 4563 at the bottom to move, and the limit seat 4563 drives the connecting shaft to move, and the connecting shaft drives the limit roller 455 and the movable pressure roller 453 to move at the same time, and the movable pressure roller 453 moves downward at the same time, flattens the wrinkles on the cloth on both sides of the cutting edge of the cutting knife 42, and presses the cloth on both sides of the cutting edge of the cutting knife 42, and then the cutting knife 42 that moves downward cuts the cloth.
