Description

Technical Field

[0001] This utility model belongs to the technical field of fiber cloth cutting equipment, specifically a microfiber cloth cutting device. Background Technology

[0002] Due to its extremely fine fineness, microfiber greatly reduces the stiffness of the silk, making the fabric extremely soft to the touch. The fineness of the fiber also increases the layered structure of the silk, increases the specific surface area and capillary effect, and makes the reflected light inside the fiber more finely distributed on the surface, giving it an elegant luster like silk, as well as good moisture absorption and dissipation properties. Before microfiber fabric is processed into finished products, it needs to be cut into sections using a cutting machine.

The device is equipped with a first drive unit for driving the moving frame and the fixed plate to move laterally; the unwinding roller and the winding roller are located on the lateral sides of the moving frame; the crank handle is connected to the winding roller; a second drive unit is provided on the processing table for driving the winding roller to rotate; the control panel is connected to the first drive unit and the second drive unit respectively. This device can first press the fiber cloth and then cut it, resulting in neat cuts and good cutting quality. However, during the cutting process of microfiber cloth, manual operation is still required for conveying the microfiber cloth roll, etc., which cannot be automated and continuous cutting, resulting in low processing efficiency.

Detailed Implementation

[0015] Please see Figures 1-4This embodiment provides a microfiber cloth cutting device, including a cutting table 1, a concave frame 2 fixedly connected to the upper surface of the cutting table 1, a cutting mechanism provided on the concave frame 2, an adsorption positioning mechanism provided on the side of the concave frame 2 near the microfiber cloth roll feeding end, and a dragging mechanism provided on the side of the cutting table 1 away from the microfiber cloth roll feeding end. The microfiber cloth roll can be directly fixedly sleeved on the unwinding roller. The unwinding roller is set with damping rotation. The unwinding machine and conveying guide roller during fiber cloth roll cutting are common technical devices, so they will not be explained in detail here. The dragging mechanism includes a concave shell 3 fixed to the outer wall of the cutting table 1. A stepper motor 4 is fixedly connected to one side of the concave shell 3. The spindle end of the stepper motor 4 passes through the radial section of the concave shell 3 and is fixedly connected to a rotating rod 5. Two driving gears 7 are fixedly sleeved on the rotating rod 5. Driven gears 8 are rotatably connected to the inner walls of the two transverse sections of the concave shell 3 via rotating shafts. Each driving gear 7 is connected to a driven gear 8 via an internal toothed belt 9. An L-shaped bracket 10 is fixedly connected to the upper surface of each internal toothed belt 9. Slide openings 11 are opened on the upper surfaces of the two transverse sections of the concave shell 3. The two L-shaped brackets 10 pass through the two slide openings 11 respectively and are fixedly connected to a mounting bracket 12. Two symmetrically arranged electric grippers 13 are fixedly connected to the upper part. When the microfiber cloth is continuously and automatically cut, the two electric grippers 13 first hold the end of the microfiber cloth on the adsorption positioning mechanism. Then, the stepper motor 4 is started to drive the rotating rod 5 to rotate. Since the two driving gears 7 are driven by the two internal toothed belts 9 and the two driven gears 8, the two internal toothed belts 9 are synchronously displaced, which in turn drives the mounting frame 12 fixed to the two L-shaped frames 10 to move, thereby driving the two electric grippers 13 to hold the end of the microfiber cloth and drag it, realizing the automatic feeding of the microfiber cloth for subsequent continuous cutting and improving processing efficiency.

[0016] like Figure 1 As shown: The cutting mechanism includes a first push rod 14 vertically fixed on the upper surface of the transverse section of the concave frame 2. The lower end of the first push rod 14 passes through the concave frame 2 and is fixedly connected to a cutting blade 15. Two symmetrically arranged guide rods 16 are fixedly connected to the upper surface of the cutting blade 15. Both guide rods 16 pass through the concave frame 2. When the microfiber cloth roll is dragged to the correct position, the first push rod 14 is activated to extend, pushing the cutting blade 15 downward to cut the microfiber cloth roll.

[0017] like Figure 1 and Figure 4As shown: The adsorption positioning mechanism includes a negative pressure pump 17 fixed to the bottom of the cutting table 1 and a frame 18 fixed to one side of the concave frame 2. A vertically arranged second push rod 19 is fixedly connected to the upper surface of the frame 18. The second push rod 19 passes through the frame 18 and is fixedly connected to a negative pressure pipe 20. A number of suction cup heads 21 arranged at equal intervals are connected to the lower surface of the negative pressure pipe 20. The negative pressure pump 17 is connected to the negative pressure pipe 20 through a hose 22. A pressure relief valve 23 is provided on the negative pressure pipe 20. When the microfiber cloth is dragged to the desired length position, the pump is activated. The second push rod 19 extends to push the suction head 21 downwards to press the microfiber cloth, preventing the microfiber cloth from shifting during cutting and ensuring cutting stability. At the same time, the negative pressure pump 17 is activated to generate negative pressure suction on the suction head 21 to adsorb and fix the cut end of the microfiber cloth. After cutting, the second push rod 19 can be activated to retract, lifting the cut end of the microfiber cloth so that the electric gripper 13 can clamp it for subsequent dragging operations, ensuring the continuity of cutting processing, high degree of automation, and improved work efficiency.

[0018] like Figure 2 As shown: The mounting bracket 12 and the electric gripper 13 are fixedly connected by locking bolts and are detachable so that the position of the electric gripper 13 can be adjusted.

[0019] like Figure 3 As shown: The inner walls of the two transverse sections of the concave shell 3 are fixedly connected with support slide plates 24. The support slide plates 24 are set against the inner upper wall of the inner toothed belt 9 to prevent the inner toothed belt 9 from bending and deforming.

[0020] like Figure 1 As shown: A control panel 6 is fixedly connected to one end of the outer wall of the cutting table 1. The control panel 6 is electrically connected to the cutting mechanism, the adsorption positioning mechanism, and the dragging mechanism. The control panel 6 uses an STM32F103 microcontroller as the control core. The peripheral circuit includes a power module, a signal acquisition module, and a drive module. It is easy to operate and has an external power supply. The circuit involved is existing technology and can be fully implemented by those skilled in the art, so there is no need to elaborate.

[0021] like Figure 2 As shown: A distance sensor 25 is fixedly connected to the middle of the upper surface of the mounting frame 12. The distance sensor 25 is set to the cutting mechanism and is used to monitor the cutting length of the microfiber cloth roll. Any errors can be compensated for by adjusting the monitored value.

[0022] Working principle: When performing continuous automated cutting of microfiber cloth, the two electric grippers 13 first clamp the end of the microfiber cloth on the adsorption positioning mechanism. Then, the stepper motor 4 is started, driving the rotating rod 5 to rotate. Since the two driving gears 7 are transmitted to the two driven gears 8 through the two internal toothed belts 9, the two internal toothed belts 9 are synchronously displaced, thereby driving the mounting frame 12 fixed to the two L-shaped frames 10 to move, thus driving the two electric grippers 13 to clamp the end of the microfiber cloth for dragging operation, realizing automatic feeding of the microfiber cloth for subsequent continuous cutting processing and improving processing efficiency; after the microfiber cloth is dragged to the desired length position, the stepper motor 4 is started. The second push rod 19 extends, pushing the suction head 21 downward to press the microfiber cloth, preventing the microfiber cloth from shifting during cutting and ensuring cutting stability. At the same time, the negative pressure pump 17 is activated, causing the suction head 21 to generate negative pressure to adsorb and fix the cut end of the microfiber cloth. After cutting, the second push rod 19 can be activated to retract, driving the cut end of the microfiber cloth to rise so that the electric gripper 13 can clamp it for subsequent dragging operations, ensuring the continuity of cutting processing, high degree of automation, and improved work efficiency. Then, the first push rod 14 extends, pushing the cutting blade 15 downward to cut the microfiber cloth roll. After cutting, the cloth can be removed.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
