Description

Technical Field

[0001] The utility model relates to the technical field of UD cloth cutting, in particular to an automatic UD cloth cutting device. Background Art

[0002] UD cloth, also known as unidirectional cloth, is a type of non-textile material / cloth, which is characterized by a large amount of textile glass yarn or roving in one direction (usually the warp direction), and only a small amount of usually finer yarn in the other direction. This structure makes the entire strength of the UD cloth mainly concentrated in the first direction, while the yarn in the weft direction mainly plays a reinforcing role. UD cloth is widely used in many fields.

[0003] For example, a cutting device for UD non-woven fabric production with announcement number CN215856906U includes a workbench, symmetrically placed positioning wheel support columns are welded at both ends of the upper surface of the workbench, two positioning wheels are rotatably connected between the positioning wheel support columns, a UD non-woven fabric passes between the two positioning wheels, a moving device is welded above the right surface of the workbench, a cutting device is connected to the moving device, a collecting device is placed on the right side of the workbench, and the UD non-woven fabric is connected to the collecting device. During the cutting process of the UD non-woven fabric, the blade can be moved together with the movement of the UD non-woven fabric in the workbench through the moving device, ensuring that the blade and the UD non-woven fabric remain relatively stationary during the processing, thereby improving the situation where traditional cutting devices cannot cut UD non-woven fabrics quickly, so that the machine needs to be paused to ensure smooth cutting.

[0023] like Figure 1-4As shown, an automatic cutting device for UD cloth comprises a workbench 1, a mounting frame 2 is slidably mounted on the top of the workbench 1, a cutting mechanism 3 for cutting UD cloth is arranged inside the mounting frame 2, the cutting mechanism 3 comprises two groups of electric cylinders 31, the two groups of electric cylinders 31 are symmetrically fixedly mounted on the inner top of the mounting frame 2, one end of the piston rod of the two groups of electric cylinders 31 is fixedly connected with a mounting plate 32, a cutting knife 33 is fixedly mounted at the center of the bottom of the mounting plate 32, three groups of buffer assemblies 34 are mounted on both sides of the mounting plate 32, and limiting plates 35 for limiting UD cloth are mounted at the bottom of the three groups of buffer assemblies 34, grooves 4 are provided on both sides of the workbench 1, driving mechanisms 5 for driving the mounting frame 2 are installed inside the two groups of grooves 4, and a guiding mechanism 6 for guiding UD cloth is installed at one end of the workbench 1.

[0024] The utility model drives the mounting plate 32 and the cutting knife 33 at the bottom thereof to descend by extending and retracting the piston ends of the two groups of electric cylinders 31 in the cutting mechanism 3, so as to cut the UD cloth on the workbench 1. When the cutting knife 33 descends, the limiting plates 35 at both sides thereof first contact the UD cloth with the cutting knife 33, and the UD cloth is pressed and limited by the limiting plates 35, so as to improve the cutting accuracy of the UD cloth.

[0025] Furthermore, the buffer assembly 34 includes a sleeve 341, which is fixedly embedded on the mounting plate 32, a spring 342 is fixedly installed on the inner top of the sleeve 341, a sliding plate 343 is fixedly installed on the bottom of the spring 342, an inner rod 344 is fixedly connected to the bottom of the sliding plate 343, and the bottom of the inner rod 344 extends to the bottom of the sleeve 341 and is fixedly connected to the top of the limiting plate 35. The above design facilitates squeezing the inner rods 344 in the three groups of buffer assemblies 34 through the limiting plate 35, and squeezing the sliding plate 343 through the inner rod 344 drives the spring 342 to contract, so that the cutting knife 33 cuts the UD cloth.

[0026] Furthermore, six groups of buffer components 34 are symmetrically distributed on both sides of the cutting blade 33, and the top of the limiting plate 35 is lower than the bottom of the cutting blade 33. The above design facilitates the limiting plate 35 to contact the UD cloth before the cutting blade 33, and the limiting plate 35 is used to press and limit the UD cloth, thereby improving the stability of the UD cloth when cutting.

[0027] Furthermore, the guiding mechanism 6 includes a fixed frame 61, which is fixedly installed on one end of the workbench 1, and an electric push rod 62 is fixedly installed on the top of the fixed frame 61. One end of the piston rod of the electric push rod 62 passes through the fixed frame 61 and is fixedly connected to a concave frame 63. A first traction roller 64 is rotatably installed inside the concave frame 63. The fixed frame 61 is located below the first traction roller 64 and is rotatably installed with a second traction roller 65, and one end of the second traction roller 65 passes through the fixed frame 61 and is connected to a second drive motor 66.

[0028] The above design facilitates the movement of the first traction roller 64 in the concave frame 63 toward the second traction roller 65 by extending and retracting the piston rod of the electric push rod 62, and facilitates the adjustment of the distance between the first traction roller 64 and the second traction roller 65 according to the thickness of the UD cloth.

[0029] Furthermore, the second driving motor 66 is fixedly mounted on one side of the fixing frame 61, and one end of the output shaft of the second driving motor 66 is fixedly connected to one end of the second traction roller 65. The above design facilitates the second traction roller 65 to rotate through the output shaft of the second driving motor 66, so that the second traction roller 65 can guide the UD cloth.

[0030] Furthermore, the first traction roller 64 and the second traction roller 65 are arranged correspondingly up and down, and the top of the second traction roller 65 is located on the same horizontal line as the surface of the workbench 1, so that the UD cloth guided by the first traction roller 64 and the second traction roller 65 slides against the surface of the workbench 1.

[0031] Furthermore, the driving mechanism 5 includes a threaded rod 51, which is rotatably mounted on one inner wall of the groove 4, one end of the threaded rod 51 is fixedly connected to a first driving motor 52, the outer wall of the threaded rod 51 is threadedly connected to a sliding block 53, and the inner walls on both sides of the mounting frame 2 are respectively fixedly connected to the opposite sides of the two sets of sliding blocks 53.

[0032] Furthermore, the outer wall of the sliding block 53 is slidably connected to the inner wall of the groove 4, and the two sets of first driving motors 52 are synchronously arranged. The above design facilitates the sliding block 53 to move only linearly in the groove 4.

[0033] Working principle: When the utility model is used, the piston rod of the electric push rod 62 in the guide mechanism 6 is extended and retracted to drive the first traction roller 64 in the concave frame 63 to move toward the second traction roller 65, so as to adjust the distance between the first traction roller 64 and the second traction roller 65 according to the thickness of the UD cloth. The first traction roller 64 and the second traction roller 65 cooperate with each other to tighten the UD cloth and guide it at the same time. The piston ends of the two groups of electric cylinders 31 in the cutting mechanism 3 are extended and retracted to drive the mounting plate 32 and the cutting knife 33 at its bottom to descend, so as to cut the UD cloth on the workbench 1. When the cutting knife 33 descends, the limiting plates 35 on both sides thereof contact the UD cloth before the cutting knife 33, and the UD cloth is pressed and limited by the limiting plates 35. The inner rods 344 in the three groups of buffer components 34 are squeezed by the limiting plates 35, and the sliding plate 343 is squeezed by the inner rods 344 to drive the spring 342 to contract, so that the cutting knife 33 cuts the UD cloth, which has the advantage of improving the cutting accuracy of the UD cloth.
