Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and specifically to a nonwoven fabric tension adjustment device. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched nonwoven fabric, etc., is a type of fabric formed without spinning or weaving. In the processing of nonwoven fabric, in order to maintain stable dimensions and ensure tight bonding between layers, the tension of the nonwoven fabric needs to be stably adjusted to prevent folding during winding. In existing nonwoven fabric tension adjustment processes, push rollers are usually used to push the nonwoven fabric during transmission to adjust the tension. However, because the longitudinal movement of the push rollers is manually operated, the real-time tension of the nonwoven fabric cannot be precisely controlled, resulting in poor tension adjustment and easily affecting the stable production of nonwoven fabric.

[0003] Therefore, we propose a nonwoven fabric tension adjustment device to solve the above problems. Utility Model Content

[0008] Both ends of the top of the base plate are fixedly provided with transmission frames. Two symmetrically arranged drive wheels are rotatably provided inside the transmission frame. A drive motor is fixedly provided on the upper end of the outer wall of the transmission frame. The output shaft of the drive motor is fixedly connected to the output end of the drive wheel.

[0009] A PLC controller is fixedly installed on the top of the base plate, and the PLC controller is electrically connected to the magnetic force adjustment mechanism and the tension sensor.

[0010] Preferably, the magnetic force adjustment mechanism includes a fixed electromagnetic block and a sliding electromagnetic block. The fixed electromagnetic block is fixedly disposed at the bottom of the inner wall of the sleeve, and the sliding electromagnetic block is slidably disposed inside the upper end of the sleeve. The bottom of the movable frame is fixedly disposed at the top of the sliding electromagnetic block.

[0011] Preferably, the fixed electromagnetic block and the sliding electromagnetic block have the same magnetic pole at their closest ends.

[0012] Preferably, the fixed electromagnetic block and the sliding electromagnetic block are fixedly provided with two symmetrically arranged telescopic rods at one end close to each other. The sleeve end of the telescopic rod is fitted with a spring, and the two ends of the spring are fixedly connected to the sleeve end and the sleeve end of the telescopic rod, respectively.

[0013] Furthermore, the tension sensor is a strain gauge tension sensor.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a nonwoven fabric tension adjustment device.

[0026] This utility model provides, for example Figure 1-3 The nonwoven fabric tension adjustment device shown includes a base plate 1 and a sleeve 2 fixedly installed on the top of the base plate 1. The sleeve 2 is equipped with a magnetic adjustment mechanism and a movable frame 3 is provided through the magnetic adjustment mechanism. A crossbar 4 is fixedly installed through the upper end of the movable frame 3. A tension sensor 5 is fixedly installed in the middle of the wall of the crossbar 4. The tension sensor 5 is a strain gauge tension sensor. Both ends of the wall of the crossbar 4 are rotatably fitted with transmission wheels 6.

[0027] The top two ends of the base plate 1 are fixedly provided with transmission frames 7. The sides of the transmission frame 7 are U-shaped. Two symmetrically arranged drive wheels 8 are rotatably provided inside the transmission frame 7. The upper end of the outer wall of the transmission frame 7 is fixedly provided with a drive motor 9. The output shaft of the drive motor 9 is fixedly connected to the output end of the drive wheel 8.

[0028] A PLC controller 10 is fixedly mounted on the top of the base plate 1. The PLC controller 10 is electrically connected to the magnetic force adjustment mechanism and the tension sensor 5.

[0029] In order to achieve real-time and precise tension control of the nonwoven fabric during the nonwoven fabric conveying process and ensure the processing effect of the nonwoven fabric, such as Figure 1 and Figure 3 As shown, the magnetic adjustment mechanism includes a fixed electromagnetic block 11 and a sliding electromagnetic block 12. The fixed electromagnetic block 11 is fixedly disposed at the bottom of the inner wall of the sleeve 2, and the sliding electromagnetic block 12 is slidably disposed inside the upper end of the sleeve 2. The magnetic poles of the fixed electromagnetic block 11 and the sliding electromagnetic block 12 are the same at their adjacent ends. The bottom of the movable frame 3 is fixedly disposed at the top of the sliding electromagnetic block 12. Two symmetrically arranged telescopic rods 13 are fixedly disposed at their adjacent ends. Springs 14 are sleeved on the sleeve ends of the telescopic rods 13, and the two ends of the springs 14 are fixedly connected to the sleeve end and the sleeve end of the telescopic rods 13, respectively.

[0030] Working principle:

[0031] When adjusting the tension of the nonwoven fabric, one end of the nonwoven fabric is inserted into the right transmission frame 7 and contacts the top of the movable frame 3, and finally exits through the left transmission frame 7. At this time, the drive motor 9 starts, causing the left drive wheel 8 to rotate and transport the nonwoven fabric. During the transport of the nonwoven fabric, the nonwoven fabric contacts the outer wall of the tension sensor 5, which compresses the tension sensor 5. At this time, the tension sensor 5 generates an electrical signal and transmits it to the PLC controller 10. Since the tension sensor 5 is a pressure-variable type tension sensor, the internal resistance of the sensor increases with the increase of pressure, causing the fixed electromagnetic block 1 connected in the same circuit to... 1. When the internal current decreases, the magnetic field strength between the fixed electromagnetic block 11 and the sliding electromagnetic block 12 decreases. This allows the sliding electromagnetic block 12 to move downwards due to its own weight and the elastic force of the spring 14. Consequently, the moving frame 3 drives the transmission wheel 6 downwards, reducing the pushing force on the nonwoven fabric. This allows the tension of the nonwoven fabric to be adjusted. At the same time, when the tension decreases, the internal resistance of the sensor decreases. The magnetic field strength between the fixed electromagnetic block 11 and the sliding electromagnetic block 12 increases due to the increase in current. This causes the sliding electromagnetic block 12 to be pushed upwards, which in turn causes the transmission wheel 6 to push the nonwoven fabric. This allows for real-time and precise control of the tension of the nonwoven fabric, ensuring stable processing of the nonwoven fabric.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
