Description

Technical Field

[0001] This utility model relates to the technical field of nonwoven fabric production equipment, and more specifically, it relates to a winding mechanism for nonwoven fabric production. Background Technology

[0002] Nonwoven fabric winding machines are used to wind pre-produced nonwoven fabric into rolls. During production, the roll core is placed on two unpowered rollers, and then the two ends of the roll core are fixed by air shafts. The air shafts drive the roll core to rotate, and the two unpowered rollers assist in winding the nonwoven fabric. When the nonwoven fabric roll reaches the set length, the winding stops, the nonwoven fabric is cut, and the nonwoven fabric roll is removed. This step is called unwinding, which is also the unloading process. Packaging and other operations are then carried out.

[0003] When the finished nonwoven fabric roll is unwound from the equipment, a receiving platform is placed below the roll. The air shaft is fixed and disassembled from both ends of the roll core. The nonwoven fabric roll is then manually moved from the receiving platform to a trolley for transport to the next process. For nonwoven fabric rolls with relatively large mass, the cylindrical shape makes them difficult to grip, causing great inconvenience in transferring the nonwoven fabric from the platform to the trolley and wasting a lot of physical effort. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a non-woven fabric production unwinding mechanism that saves labor and has high work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nonwoven fabric production unwinding mechanism, comprising lifting devices located on both sides of a non-powered winding roller, and a guide device located in front of the non-powered winding roller. The lifting device includes a support rod driven up and down by a cylinder. A rotatable support bracket is hinged to the first end of the support rod. A limiting sleeve is provided over the support rod, and a flipping notch is provided at the opening of the limiting sleeve. The support rod is driven upward by the cylinder until the support bracket is moved to the flipping notch, at which point the support bracket flips towards the guide device. The guide device includes a connecting part and a conveying part. The connecting part can flip towards the conveying part, and the conveying part is inclined, tilting downward from the connecting part end towards the other end.

[0006] The present invention is further configured such that: the connecting part includes a connecting plate, one end of the connecting plate is inserted with a rotating shaft, and the connecting plate can be flipped toward the conveying part along the rotating shaft.

[0007] The present invention is further configured such that: the conveying part includes an inclined frame and a plurality of transmission rollers disposed within the inclined frame, the transmission rollers being laid out as a guide conveying surface.

[0008] The present invention is further configured such that: the support bracket includes a U-shaped frame, the bottom of the frame is provided with a movable block having a movable groove, the end of the support rod is provided with an insert block, the insert block is inserted into the movable groove of the movable block and is engaged by a rotating pin.

[0009] The present invention is further configured such that a guide slope is provided on the side of the frame near the guide device.

[0010] By adopting the above technical solution and adding a lifting device, the non-woven fabric roll can be automatically dropped onto the guide device by flipping. Then, through the connecting part and the conveying part, the non-woven fabric roll can automatically slide down to the designated work position along the guide conveying surface, reducing the labor output of manual handling and improving work efficiency.

[0017] Reference Figures 1 to 5 The embodiments of this utility model will be further described below.

[0018] A nonwoven fabric production unwinding mechanism includes lifting devices 2 located on both sides of a non-powered winding roller 1, and a guide device 3 located in front of the non-powered winding roller 1. The lifting devices 2 include a support rod 20 driven up and down by a cylinder. A rotatable support bracket 21 is hinged to the first end of the support rod 20. A limiting sleeve 22 is provided on the support rod 20. A flipping notch 23 is provided at the opening of the limiting sleeve 22. The support rod 20 is driven upward by the cylinder until the support bracket 21 is moved to the flipping notch 23. The support bracket 21 will then flip towards the guide device 3. The guide device 3 includes a connecting part and a conveying part. The connecting part can flip towards the conveying part. The conveying part is inclined and tilted downward from the connecting part end towards the other end. The support bracket 21 includes a U-shaped frame 24. The bottom of the frame 24 is provided with a movable block 25 having a movable groove 28. The end of the support rod 20 is provided with an insert 26, which is inserted into the movable groove 28 of the movable block 25 and engaged by a rotating pin. The side of the frame 24 near the guide device 3 is provided with a guide slope 27.

[0019] The connecting part includes a connecting plate 30, one end of which is inserted with a rotating shaft. The connecting plate 30 can be flipped along the rotating shaft toward the conveying part. The conveying part includes an inclined frame 31 and a plurality of drive rollers 32 disposed within the inclined frame 31. The drive rollers 32 are laid out to form a guide conveying surface 33.

[0020] Working principle: When the roll core completes the winding of the nonwoven fabric and needs to be unwound, the air shaft is disassembled from both ends of the roll core. The cylinder on the lifting device 2 drives the support rod 20 to move upward, and the support bracket 21 moves to the end of the roll core, lifting the roll core. As the support rod 20 moves upward, it lifts the nonwoven fabric roll 4 above the non-powered roller 1. When the height of the support bracket 21 rises to the flipping notch 23 of the limit sleeve 22, the support bracket 21 will flip in the direction of the guide device 3, and the nonwoven fabric roll 4 will fall onto the connecting part. Since the connecting plate 30 on the connecting part only has a rotating shaft on the side close to the non-powered roller 1, when the nonwoven fabric roll 4 falls, it will be subjected to gravity and flip along the rotating shaft towards the conveying part. Then, it will roll down along the guide slope 27 on the conveying part to the designated station. The transmission roller 32 plays a role in assisting the rolling of the nonwoven fabric roll 4, speeding up the unwinding and unloading efficiency. The above structural improvements reduce the labor required for manual handling and have the advantage of improving work efficiency.

[0021] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
