Technical Field

[0001] This utility model relates to the field of material receiving equipment, specifically a material receiving equipment based on speed control using a displacement sensor. Background Technology

[0002] In traditional roll material slitting and winding equipment, the moving speed of the wire guide is generally controlled by a fixed-speed motor or mechanical limit device, which has the following drawbacks: the speed adjustment range is limited, and it is impossible to achieve a transition between high speed and low speed; the wire guide position is difficult to automatically correct, and uneven distribution is easy to occur; the tension control response is not timely, which can easily cause the material to wrinkle and stretch unevenly; the overall structure of the equipment is complex and the maintenance cost is high.

[0003] To address the aforementioned issues, there is an urgent need for a compact, responsive wire take-up device capable of closed-loop control and stepless speed regulation, in order to improve production efficiency and product quality. Utility Model Content

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. In the embodiments of the present utility model, the different types of cross-sectional lines are not labeled according to national standards, nor do they specify material requirements for the components; they are used to distinguish the cross-sectional views of the components in the drawings.

[0019] Please see Figure 1-3 A material receiving device based on displacement sensor speed control includes a displacement sensor 1, a tension adjusting cylinder 2, a tension adjusting cylinder assembly 3, a synchronous pulley 4, a synchronous belt 5, a motor 6, a fuma wheel 7, a linear bearing flange 8, a graphite copper sleeve 9, a mechanical tensioning coupling 10, and a deep groove ball bearing 11. The motor 6 is connected to the synchronous pulley 4 via the synchronous belt 5; the synchronous pulley 4 drives the wire feeding mechanism; the displacement sensor 1 is positioned above the wire feeding path and connected to a frequency converter via a signal line, and is used to detect the offset state of the wire feeding mechanism; the tension adjusting cylinder 2... The tension adjustment cylinder assembly 3 works in conjunction with the tension control cylinder to control material tension; the mechanical tension coupling 10 connects the motor output shaft and the take-up shaft; the linear bearing flange 8 and the graphite copper sleeve 9 are used to guide and support the wire laying device; the fuma wheel 7 and the deep groove ball bearing 11 support the movement and rotation of the entire device; the displacement sensor 1 controls the frequency converter through feedback signals, so that the speed of the motor 6 can be infinitely adjusted within the range of 0 to 400 m / min; the tension adjustment cylinder assembly 3 includes a cylinder rod, a bracket, a movable arm and a flexible tension traction structure; the synchronous pulley 4 drives the wire laying shaft through the belt 5 to achieve lateral wire laying action.

[0020] Among them, the mechanical tension coupling 10 adopts an elastic structure design; the linear bearing flange 8 is installed on the guide rail slide, and together with the graphite copper sleeve 9, it forms a low-friction, high-wear-resistant cable guide structure.

[0021] Among them, the Foma wheel 7 has a universal structure and is installed at the four corners of the bottom, which facilitates the movement and adjustment of the overall device.

[0022] Among them, the deep groove ball bearing 11 is used to support the guide roller or rotating shaft of the cable, and has low noise and high load capacity.

[0023] Among them, motor 6 is a closed-loop control motor with an encoder, which works in conjunction with the frequency converter to achieve precise speed control.

[0024] The entire system constitutes a closed-loop control logic. Displacement sensor 1 constantly monitors the position deviation of the cable tray. When it deviates from the center position, the frequency of the inverter is adjusted to achieve automatic correction.

[0025] It should be noted that when the equipment is started, the motor 6 starts working under the control of the frequency converter, and drives the wire guide shaft through the synchronous belt 5 and the synchronous pulley 4. The wire guide moves back and forth on the guide rail, thereby achieving uniform distribution of the roll material.

[0026] The key technology lies in the closed-loop control function of displacement sensor 1. Displacement sensor 1 is fixed on the cable guide rail and continuously detects the current position of the cable guide. When the cable guide deviates to the preset center position to the left or right, the displacement sensor immediately transmits the displacement amount to the frequency converter control system in the form of an electrical signal. The frequency converter then automatically adjusts the operating frequency and speed of motor 6 according to the deviation value.

[0027] For example, if the cable guide moves too quickly to the left off-center, the displacement sensor detects this deviation and controls the frequency converter to reduce the motor frequency, slowing down the leftward movement and allowing the cable guide to return to center. Conversely, if the offset is insufficient or the cable guide is offset to the right, the frequency converter increases the frequency to speed up the cable guide and compensate for the shortfall.

[0028] This closed-loop control system enables the cable guide to dynamically adjust its speed around the center position throughout the entire working process, achieving stepless speed control of the cable guide shaft from 0 to 400 m / min.

[0029] Meanwhile, as the material passes through the equipment, the tension is controlled by the tension regulating cylinder 2 and its component 3. This is achieved by the cylinder pushing the movable arm to change the position of the guide rollers in the material channel, thereby dynamically adjusting the material tension and preventing slack or tightness.

[0030] The mechanical tension coupling 10 absorbs the impact force caused by the reciprocating movement of the cable guide during motor output, ensuring stable operation of the transmission system. The linear bearing flange 8 and the graphite copper sleeve 9 provide a highly wear-resistant, low-resistance movement path, further improving the service life and accuracy of the cable guide.

[0031] During the operation of the entire system, the motor, frequency converter, and displacement sensor form a closed-loop control logic, automatically adjusting the winding speed and wire laying rhythm. The 7-pin wheel and the deep groove ball bearing 11 provide the necessary motion support and a low-noise transmission environment for the equipment structure.
