Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, and more specifically, to a nonwoven fabric conveying assembly. Background Technology

[0002] When nonwoven fabric is being wound up, it needs to be conveyed to the winding roller via a conveying assembly. To prevent the nonwoven fabric from becoming too loose during winding, a fabric tensioning roller is usually installed between the conveying assembly and the winding roller.

[0003] However, once the existing fabric tensioning roller is adjusted and pressed against the nonwoven fabric, the position of the tensioning roller becomes fixed. After the nonwoven fabric is transported for a long time, slight changes in tension are inevitable, which will have a certain impact on the winding of the nonwoven fabric. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a nonwoven fabric conveying assembly to solve the problems mentioned in the background art.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution:

[0025] A nonwoven fabric conveying assembly, please refer to Figures 1-7 It includes multiple conveying rollers 21, a pressure bar 22 between two adjacent conveying rollers 21, and a take-up roller 31. The nonwoven fabric is taken up by the take-up roller 31 after passing the lower part of the pressure bar 22 and the upper part of the conveying rollers 21.

[0026] Specifically, it also includes two parallel side plates 20, with conveying rollers 21 and pressure rods 22 rotatably connected between the two side plates 20. At least one conveying roller 21 is driven to rotate by a motor, and two adjacent conveying rollers 21 are connected by a sprocket drive. This conveying method is a conventional conveying method. It also includes a base plate 10, with support legs fixedly connected to the bottom of the side plates 20 near both ends. The bottom ends of the support legs are fixed to the base plate 10.

[0027] Furthermore, a nonwoven fabric tension adjustment assembly is provided between the conveying roller 21 and the winding roller 31, which is close to the winding roller 31.

[0028] The nonwoven fabric tension adjustment assembly includes a tension roller 55 and two parallel vertical plates 50. The bottom end of the vertical plates 50 is fixedly connected to the base plate 10. Slide strips 53 are slidably provided on the side of the two vertical plates 50 near the tension roller 55 in the vertical direction. Specifically, a slide seat 52 is fixedly connected to the side of the vertical plate 50 near the tension roller 55, and the slide strips 53 are slidably connected to the slide seat 52.

[0029] The tension roller 55 is rotatably connected between two slide bars 53. Specifically, each of the two slide bars 53 has a fixed seat 54 fixedly connected to one side of each other. The two ends of the tension roller 55 are rotatably connected to the two fixed seats 54 respectively. The lower part of the tension roller 55 presses against the non-woven fabric. A block 51 is provided on the vertical plate 50 below the slide bars 53. It also includes an adjustment component. The adjustment component is used to adjust the position of the block 51 in the vertical direction of the vertical plate 50. The slide bars 53 and the block 51 below them are connected by a tension spring 56.

[0030] The bottom of the slider 53 is provided with a second connecting ear 532, and the top of the block 51 is provided with a first connecting ear 510. Both the first connecting ear 510 and the second connecting ear 532 are provided with hanging holes. Both ends of the tension spring 56 are provided with hooks, and the two hooks of the tension spring 56 are respectively hung in the two hanging holes.

[0031] In this invention, after the tension roller 55 tensions and presses the nonwoven fabric, if the nonwoven fabric becomes too loose after prolonged use, the tension roller 55 will automatically move downward under the action of the tension spring 56 to automatically tighten the nonwoven fabric, thereby preventing the nonwoven fabric from becoming too loose after winding. When the fabric is too tight, the tension force of the fabric itself can also push the tension roller 55 upward, preventing the nonwoven fabric from being too tight for a long time and causing damage due to excessive tension. The tension roller 55 of this application can automatically adjust the tension according to the tightness of the fabric, greatly improving the practicality of the device.

[0032] The adjustment assembly includes a threaded post 511, a nut 512, and a strip groove 500 formed on the vertical plate 50. The middle part of the threaded post 511 is movably disposed in the strip groove 500. One end of the threaded post 511 is fixedly connected to the block 51, and the nut 512 is threadedly connected to the other end of the threaded post 511.

[0033] By loosening the nut 512, the block 51 can be pushed up and down, and the block 51 can be adjusted to a suitable height position. When it is necessary to fix the block 51, make one side of the block 51 abut against the vertical plate 50, and then tighten the nut 512 to lock the block 51 onto the vertical plate 50.

[0034] The adjustable height of block 51 facilitates the adaptation of tension springs 56 with different tension levels, and makes it easy for both ends of tension spring 56 to connect with block 51 and slide bar 53; it also makes it easy to adjust the pressure of tension roller 55 on nonwoven fabric.

[0035] In use, pushing the slider 53 downward will cause the tension roller 55 to move downward, so that the tension roller 55 abuts against the nonwoven fabric. Then, by adjusting the block 51 downward, the tension spring 56 can pull the slider 53 and the tension roller 55 downward, thereby facilitating the adjustment of the tension of the tension roller 55 pressing the nonwoven fabric. After adjustment, the nut 512 can be tightened to lock and fix the block 51.

[0036] To facilitate pushing the slide bar 53, a limit stop 530 is fixedly connected to the top of the slide bar 53, and a handle 531 is fixedly connected to the top of the limit stop 530.

[0037] In this invention, the lengths of the take-up roller 31 and the tension roller 55 are greater than the length of the conveyor roller 21, and the length of the conveyor roller 21 is greater than the width of the nonwoven fabric.

[0038] See Figures 3-5 A fixing block 60 is fixedly connected to the vertical plate 50, and a horizontally arranged guide rod 61 is fixedly connected to the fixing block 60. A sliding sleeve seat 62 is slidably sleeved on the guide rod 61. An infrared detector 64 is installed on the top of the sliding sleeve seat 62. It also includes a locking bolt 63 for locking the sliding sleeve seat 62 onto the guide rod 61. The sliding sleeve seat 62 is provided with a threaded hole, and the locking bolt 63 is threadedly connected to the threaded hole. Tightening the locking bolt 63 so that its end abuts against the guide rod 61 can lock the sliding sleeve seat 62 onto the guide rod 61.

[0039] The position of the infrared detector 64 is adjustable, making it easy to adapt to nonwoven fabrics of different widths.

[0040] Two infrared detectors 64 are located at the two sides of the non-woven fabric and are used to detect the non-woven fabric. Specifically, the distance between the two infrared detectors 64 and the two sides of the non-woven fabric can be adjusted to 1cm-3cm to ensure that the distance between the two infrared detectors 64 and the two sides of the non-woven fabric is the same.

[0041] It also includes an alarm and a controller. The alarm and infrared detector 64 are electrically connected to the controller. When one of the infrared detectors 64 fails to detect the non-woven fabric (indicating that the non-woven fabric has shifted), the infrared detector 64 that fails to detect the non-woven fabric transmits a signal to the controller. The controller then controls the alarm to sound an alarm, thereby reminding the staff to perform timely non-woven fabric correction and maintenance.

[0042] It also includes a drive assembly for driving the take-up roller 31 to move axially. The drive assembly includes a guide rail 41 and a movable seat 40 slidably disposed on the guide rail 41. The guide rail 41 is fixedly mounted on the base plate 10. The guide rail 41, the movable seat 40 and the take-up roller 31 are parallel to each other. It also includes a cylinder 43 for driving the movable seat 40 to move along the guide rail 41. The cylinder 43 is mounted on the base plate 10. A fixed plate 42 is fixedly connected to the side of the movable seat 40 near the cylinder 43. The extended end of the cylinder 43 is fixedly connected to the fixed plate 42. By controlling the extension and retraction of the cylinder 43, the movable seat 40 can be driven to move on the guide rail 41. Two support plates 30 are fixedly connected to the movable seat 40. The take-up roller 31 is rotatably disposed between the two support plates 30. By controlling the extension and retraction of the cylinder 43, the movable seat 40 can be driven to move on the guide rail 41, thereby adjusting the horizontal movement of the take-up roller 31, which is convenient for adjusting the take-up roller 31 to a suitable position before winding up the nonwoven fabric.

[0043] It is worth noting that the winding roller 31 is driven by a motor when winding. This drive is a conventional setting, but the winding roller 31 and the two support plates 30 can also be set to be detachably connected as needed.

[0044] Optionally, cylinder 43 can also be electrically connected to the controller. When one of the infrared detectors 64 fails to detect the nonwoven fabric (indicating that the nonwoven fabric has shifted), the infrared detector 64 that fails to detect the nonwoven fabric transmits a signal to the controller. The controller then controls the alarm to sound, and simultaneously controls cylinder 43 to move the winding roller 31 a certain distance toward the side of the nonwoven fabric that has shifted (this distance is the distance between the two infrared detectors 64 located at the two edges of the nonwoven fabric). This prevents wrinkles from forming in the nonwoven fabric when workers attempt to correct the nonwoven fabric in time.
