Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a tension regulating device for non-woven fabric processing equipment. Background Art

[0002] Spunbond is one of the main methods for producing nonwoven materials, also known as spinning web method or polymer extrusion web method. The principle of spunbond is to use the method of chemical fiber spinning to spin, draw, and lay polymers into a web, and finally reinforce them by needle punching, hydroentanglement, hot rolling or self-bonding to form a nonwoven material. Nonwoven fabrics made by spunbond have the characteristics of moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in colors, low price, and recyclable. In the process of nonwoven fabric production, it is necessary to adjust the surface tension of the nonwoven fabric so that its surface tension reaches a balanced state to improve the quality of the nonwoven fabric.

[0003] Existing non-woven fabric processing equipment generally only adjusts the tension of the non-woven fabric by changing the position of a supporting roller, which makes the tension adjustment slow and not sensitive enough. The tension adjustment device cannot adapt to non-woven fabrics of different widths. It has few usage scenarios and cannot limit the passing non-woven fabric. The non-woven fabric may be skewed and wrinkled during the transportation process. Utility Model Content

[0004] In order to solve the problems mentioned in the above background technology, the utility model provides a tension adjustment device for non-woven fabric processing equipment.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A tension adjustment device for non-woven fabric processing equipment comprises a support seat, a first adjustment box is fixed on the top of the support seat, three slide rails are fixed inside the first adjustment box, a slider is installed on the slide rail, a one-way threaded rod is provided on both sides of the slide rail, threaded sleeves are fixed on both sides of the slider, the two threaded sleeves are respectively threadedly installed on the outside of the two one-way threaded rods, a first gear is fixed at one end of the one-way threaded rod, a second gear is rotatably installed at one end of the slide rail, the second gear is located between the two first gears and meshes with the two first gears, a third gear is coaxially fixed on the side of the second gear away from the slide rail, a connecting rod is fixed on the slider, one end of the connecting rod extends to the outside of the first adjustment box and is connected to the non-woven fabric support mechanism.

[0007] Preferably, a first rotating motor is fixed to one side of the first adjusting box, an output shaft of the first rotating motor extends into the interior of the first adjusting box and is fixed with a driving gear ring, and the three third gears are all meshed with the driving gear ring.

[0008] Preferably, the nonwoven fabric supporting mechanism comprises a second adjusting box, on which two movable mounting frames are provided, and the first supporting half-roller and the second supporting half-roller are rotatably mounted on the sides of the two movable mounting frames close to each other.

[0009] Preferably, a plurality of horizontally arranged guide rods are fixed to a side of the first supporting half-roller close to the second supporting half-roller, and the second supporting half-roller is provided with guide grooves corresponding to the guide rods.

[0010] Preferably, a bidirectional threaded rod is rotatably installed inside the second adjustment box, a second rotating motor is fixed outside the second adjustment box, the output shaft of the second rotating motor is fixed to the bidirectional threaded rod, and two horizontal moving blocks are installed on the external threads of the bidirectional threaded rod, and the two horizontal moving blocks are respectively fixed to two movable mounting frames.

[0011] Preferably, a plurality of elastic lifting and retracting rods are fixed to the outer sides of the ends of the first supporting half-roller and the second supporting half-roller which are away from each other through a fixing ring, and a limiting roller is rotatably installed on the telescopic end of the elastic lifting and retracting rod, and the plurality of limiting rollers are evenly distributed around the first supporting half-roller or the second supporting half-roller.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The first adjustment box is a disc-shaped structure. When the second gear rotates, the one-way threaded rods on both sides of the slider can be driven to rotate synchronously through the meshing of the second gear and the first gear, so as to drive the slider to slide on the slide rail. When the three sliders move synchronously, the three non-woven fabric support mechanisms can be driven to move away from and close to the center of the first adjustment box synchronously. The non-woven fabric support mechanism is a movable roller, and the non-woven fabric is stretched straight by the movable roller (as shown in the figure). By moving the positions of the non-woven fabric support mechanisms away from each other, the non-woven fabric can be stretched to increase the tension, otherwise it can reduce the tension. Compared with moving only one movable roller during the adjustment process, the adjustment is more sensitive and the tension can be changed more quickly;

[0014] 2. The second adjustment box can drive the first supporting half roller and the second supporting half roller to move closer to or farther from each other. By changing the distance between the first supporting half roller and the second supporting half roller, the first supporting half roller and the second supporting half roller can support non-woven fabrics of different widths, and the application scenarios are more extensive;

[0015] 3. The edge of the non-woven fabric can extend between the limiting roller and the first supporting half roller or the second supporting half roller, so that the limiting roller can be pushed by the elastic force of the elastic lifting and shrinking rod to press the non-woven fabric tightly, making it difficult for the non-woven fabric to deviate or wrinkle during transportation.

[0027] The first adjustment box 2 is a disc-shaped structure. When the second gear 10 rotates, the one-way threaded rods 7 on both sides of the slider 5 can be driven to rotate synchronously through the meshing of the second gear 10 and the first gear 9, so as to drive the slider 5 to slide on the slide rail 4. When the three sliders 5 move synchronously, the three non-woven fabric support mechanisms can be driven to move away from and close to the center of the first adjustment box 2 synchronously. The non-woven fabric support mechanism is a movable roller, and the non-woven fabric is stretched straight by the movable roller (such as Figure 3 ), by moving the non-woven fabric support mechanisms away from each other, the non-woven fabric can be tightened to increase the tension, and vice versa to reduce the tension. Compared with moving only one movable roller during the adjustment process, the adjustment is more sensitive and the tension can be changed more quickly.

[0028] A first rotating motor 3 is fixed to one side of the first adjusting box 2, an output shaft of the first rotating motor 3 extends to the inside of the first adjusting box 2 and is fixed with a driving gear ring 12, and the three third gears 11 are all meshed with the driving gear ring 12;

[0029] The first rotating motor 3 can drive the driving gear ring 12 to rotate. When the driving gear ring 12 rotates, it can simultaneously drive the three third gears 11 to rotate, thereby simultaneously driving the three second gears 10 to rotate, and further simultaneously driving the six unidirectional threaded rods 7 to rotate, thereby simultaneously changing the positions of the three non-woven fabric support mechanisms.

[0030] The nonwoven fabric support mechanism includes a second adjustment box 13, on which two movable mounting frames 17 are provided, and a first supporting half roller 18 and a second supporting half roller 19 are rotatably mounted on the sides of the two movable mounting frames 17 close to each other, and a plurality of horizontally arranged guide rods 20 are fixed on the side of the first supporting half roller 18 close to the second supporting half roller 19, and a guide groove corresponding to the guide rod 20 is opened on the second supporting half roller 19;

[0031] The second adjustment box 13 can drive the first supporting half-roller 18 and the second supporting half-roller 19 to move closer to and away from each other. By changing the spacing between the first supporting half-roller 18 and the second supporting half-roller 19, the first supporting half-roller 18 and the second supporting half-roller 19 can support non-woven fabrics of different widths, which has a wider range of usage scenarios.

[0032] A bidirectional threaded rod 15 is rotatably mounted inside the second adjustment box 13, a second rotary motor 14 is fixed outside the second adjustment box 13, an output shaft of the second rotary motor 14 is fixed to the bidirectional threaded rod 15, two horizontal moving blocks 16 are installed on the external threads of the bidirectional threaded rod 15, and the two horizontal moving blocks 16 are respectively fixed to two movable mounting frames 17;

[0033] The second rotary motor 14 can drive the bidirectional threaded rod 15 to rotate, and further drive the two horizontal moving blocks 16 to move closer to or away from each other, so as to adjust the distance between the first supporting half roller 18 and the second supporting half roller 19 .

[0034] Among them, multiple elastic lifting and shrinking rods 22 are fixed to the outer sides of the ends of the first supporting half roller 18 and the second supporting half roller 19 that are away from each other through a fixing ring 21, and the telescopic ends of the elastic lifting and shrinking rods 22 are rotatably installed with limiting rollers 23, and the multiple limiting rollers 23 are evenly distributed around the first supporting half roller 18 or the second supporting half roller 19;

[0035] The edge of the non-woven fabric can extend between the limiting roller 23 and the first supporting half roller 18 or the second supporting half roller 19, so that the elastic force of the elastic lifting rod 22 can push the limiting roller 23 to press the non-woven fabric, making it less likely for the non-woven fabric to shift or wrinkle during transportation.
