Description

Technical Field

[0001] The utility model relates to the technical field of cloth processing, in particular to an anti-deviation device for folding non-woven fabrics. Background Art

[0002] Non-woven fabrics, also known as nonwovens, are made of oriented or random fibers and are a new generation of environmentally friendly materials. They are popular among the public due to their moisture-proof, breathable, flexible, lightweight, non-combustible, easily decomposable, non-toxic and non-irritating, rich colors, low price, and recyclability. The production process of non-woven fabrics is currently semi-mechanical and semi-manual, and the folding process can now be automated by machinery.

[0003] However, during the mechanized folding process of nonwoven fabrics, the wide variety of nonwoven fabrics and their varying physical properties (such as thickness, hardness, and elasticity) can lead to uneven tension or deformation during the folding process, causing deviation. This is especially true when the thickness of the nonwoven roll is inconsistent during the manufacturing process, resulting in uneven thickness on both sides of the roll, which can cause the roll edges to become loose. This phenomenon can also cause the roll to deviate. Furthermore, factors such as the stability, speed, and tension control of the conveyor system can affect the folding process. An unstable conveyor system or improper tension control can also cause the nonwoven fabric to deviate during the folding process. Utility Model Content

[0004] In response to the above-mentioned defects, the present invention provides an anti-deviation device for folding non-woven fabrics, which can provide a certain tension for the non-woven fabrics to prevent deviation during the folding process, and can also perform fine-tuning even if deviation occurs during the folding process.

[0005] The top of described sliding panel also is provided with an interlocking structure, and the interlocking structure of said frame is that of an impeller, and the end of said interlocking structure is that of an impeller, and the end of said interlocking structure is that of an impeller.

[0006] The top of described sliding panel also is provided with an interlocking plate, and the interlocking plate is hinged on the base plate, is fixed with a backing plate, and an end of sliding panel withstands on the backing of the backing plate, and the like is locked.

[0007] As a further improvement of the present invention, a movable groove is provided on the locking block, and the support rod is fitted in the movable groove and fixed by fastening nuts on the upper and lower sides.

[0008] As a further improvement of the present invention, both ends of the deviation-correcting shaft can be rotatably connected to a shaft frame, and the shaft frame is fixedly connected to the frame.

[0009] As a further improvement of the present invention, one end of the deviation-correcting shaft is fixedly connected to a turning handle.

[0010] As a further improvement of the present invention, a fourth cloth guide roller is rotatably connected between the two side plates.

[0011] As a further improvement of the present invention, one end of the bearing sleeve away from the frame is fixedly connected to a handle.

[0012] As a further improvement of the present invention, bosses are provided on the outer sides of the supporting plates at both ends of the discharge shaft.

[0013] As a further improvement of the present invention, the cloth guide rollers include a first cloth guide roller, a second cloth guide roller, and a third cloth guide roller.

[0014] As a further improvement of the present invention, the first cloth guide roller is located in the middle of the mounting plate, and the second cloth guide roller and the third cloth guide roller are located on the same horizontal plane at the lower part of the mounting plate.

[0015] Beneficial effects of the utility model:

[0016] 1. By setting up a belt roller, fix the pulley with a belt fixed on one end to the belt roller, and fix the counterweight block at the end of the belt, the belt is in contact with the non-woven fabric mother roll. Since the counterweight block has a certain gravity, the belt will press the non-woven fabric mother roll, so that the non-woven fabric mother roll always maintains a certain tension, thereby preventing its deformation and avoiding deviation.

[0017] 2. By rotating the grip and handle, lateral fine-tuning can be performed during the folding process of the non-woven fabric. Once deviation occurs, synchronous manual adjustment can be performed in real time to maintain the stability of the system folding and improve the folding quality of the non-woven fabric.

DETAILED DESCRIPTION

[0023] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific examples described herein are merely illustrative of the present invention and are not intended to limit the present invention. Directional terms such as up, down, left, right, front, or back, mentioned in the following embodiments, are merely references to the directions in the accompanying drawings. Therefore, the directional terms used are intended to illustrate and not to limit the present invention. Furthermore, throughout the embodiments, the same reference numerals represent the same elements.

[0024] like Figures 1 to 4 The nonwoven fabric folding anti-deviation device shown includes a frame 1, one end of which is free of a panel. A support plate 2 is provided at this end of the frame 1. Two support plates 2 are fixed to opposite sides of the frame 1. Support holes are formed in the support plates 2, which are open toward the side away from the frame 1.

[0025] A discharge shaft 3 rotatably fits within the support hole of the support plate 2. Bosses 30 are provided at both ends of the shaft, located outside the support plate 2 and spaced a certain distance apart. An annular bearing groove 31 is defined at one end of the shaft 3. A bearing 4 is fitted within this groove. Bearing 4 utilizes an angular contact ball bearing or deep groove ball bearing capable of bearing both radial and axial forces.

[0026] The bearing 4 is fixedly connected to the bearing sleeve 7, and the end of the bearing sleeve 7 away from the frame 1 is fixedly connected to the handle 5. The interior of the bearing sleeve 7 is provided with an internal thread, and the bearing sleeve 7 is matched with the adjustment shaft 6 with an external thread through the internal thread. The adjustment shaft 6 is fixedly connected to the side of the frame 1.

[0027] As a further illustration of this example, rotating the handle 5 causes the bearing sleeve 7 and the bearing 4 to shift along the adjustment shaft 6. During movement, since the bearing 4 matches the bearing matching groove 31 on the discharge shaft 3, the discharge shaft 3 will be pushed to move slightly through the bearing 4.

[0028] A nonwoven fabric roll 8 is wrapped around the unwinding shaft 3. Two mounting plates 19 are mounted on the frame 1 inside the unwinding shaft 3. These mounting plates 19 are fixed to either side of the frame 1, with several rollers positioned between them. A belt roller 12 is fixed to the top of the mounting plates 19. A pulley 9 is fixed to the middle of the belt roller 12. A belt 10 is secured to one end of the pulley 9. The belt 10 passes over the nonwoven fabric roll 8, maintaining constant contact and enabling flexible engagement with it. A counterweight 11 is fixedly attached to the end of the belt 10, extending vertically downward.

[0029] As a further illustration of this example, a counterweight 11 is fixed to the end of the belt 10. The counterweight 11 will tighten the belt 10 under the force of gravity, and the belt 10 will be pressed on the non-woven fabric roll 8. Since the weight of the counterweight 11 remains unchanged, the belt 10 will be pressed on the non-woven fabric roll 8, so that it always maintains a certain tension.

[0030] The middle part of the mounting plate 19 is rotatably connected to the first cloth guide roller 13, and the lower part of the mounting plate 19 is rotatably connected to the second cloth guide roller 14 and the third cloth guide roller 15. The second cloth guide roller 14 and the third cloth guide roller 15 are both located at the same horizontal height and are arranged side by side.

[0031] A correction device is fixedly connected to the frame 1 on the side of the mounting plate 19 away from the support plate 2. The correction device includes side plates 17 fixedly connected to both ends of the frame 1, and a fourth cloth guide roller 16 is rotatably connected between the two side plates 17. A top plate 18 is fixedly connected to the top of one end of the two side plates 17 away from the fourth cloth guide roller 16. A shaft plate 180 is fixedly connected to both sides of the bottom of the top plate 18, and a shaft hole is provided in the middle of the shaft plate 180, in which a correction shaft 27 is rotatably connected. Both ends of the correction shaft 27 can be rotatably engaged on the shaft frame 28, and the shaft frame 28 is fixedly connected to the frame 1. A turning handle 29 is fixedly connected to the end of one side of the correction shaft 27.

[0032] A correcting thread 270 is provided in the middle of the correcting shaft 27 , and a correcting block 26 with an internal thread is matched in the middle of the correcting shaft 27 . The top of the correcting block 26 abuts against the top plate 18 to prevent the correcting block 26 from rotating.

[0033] As a further illustration of this example, rotating the handle 29 can cause the correction shaft 27 to rotate, and the correction block 26 in the middle of the correction shaft 27 will be offset due to the threaded fit, thereby driving the guide plate 20 fixed thereto to move, thereby achieving correction during the folding process of the non-woven fabric.

[0034] The side of the deflection correction block 26 near the fourth cloth guide roller 16 is fixedly connected to the lower vertical portion of the guide plate 20. The upper-middle portion of the guide plate 20 is located above the top plate 18 and is tilted at a certain angle to the horizontal plane. A support plate 21 is fixed to the bottom of the guide plate 20. The bottom of the support plate 21 is hinged to the top of a support rod 22, which is tilted and bent at its top. The lower-middle portion of the support rod 22 is vertically arranged, and the lower portion of the support rod 22 fits within a movable groove 230 in the middle of the locking block 23. Fastening nuts 25 are provided on the support rod 22 on both the upper and lower sides of the movable groove 230, clamping the support rod 22 to the locking block 23 via the fastening nuts 25. A certain distance is left between the locking block 23 and the frame 1. One end of the locking block 23 is fixedly connected to the bottom of the top plate 18, and the other end is fixedly connected to the top of a pad 24, which is laterally fixed to the frame 1.

[0035] As a further explanation of this example, when the height of the guide plate 20 needs to be adjusted according to the width of the non-woven fabric, the fastening nut 25 on the upper side of the support rod 22 can be screwed, and then the position of the support rod 22 can be adjusted, so that the contact position between the support plate 21 at the top of the support rod 22 and the guide plate 20 changes, thereby changing the angle between the guide plate 20 and the horizontal plane, thereby achieving adjustment of the height of the guide plate 20.

[0036] The working principle and use process of this utility model:

[0037] Place the discharge shaft 3 wrapped with the non-woven masterbatch on the support plate 2, place the belt 10 with the counterweight 11 on top of the non-woven masterbatch, and then guide the non-woven fabric through the first guide roller 13, the third guide roller 15, and the second guide roller 14 in sequence, and then pass under the fourth guide roller 16 and fall onto the guide plate 20. Since the guide plate 20 is triangular, when the non-woven fabric moves along the guide plate 20 to reach the end, the two ends of the non-woven fabric will fall to both sides of the guide plate 20, thereby achieving a single folding of the non-woven fabric. When it is observed that the folding of the non-woven fabric is offset, the movement trajectory of the non-woven fabric is fine-tuned by turning the handle 5 or the turning handle 29, so that the folding of the non-woven fabric returns to normal. The above is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above-mentioned implementation measures. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications without departing from the principle of the present invention should also be regarded as within the scope of protection of the present invention.
