Description

Non-woven fabrics rolling dabber Technical Field The utility model relates to the technical field of non-woven fabric production, in particular to a non-woven fabric winding mandrel. Background The non-woven fabric is a flexible material formed by combining oriented or randomly arranged fibers through mechanical, thermal or chemical methods, and is widely applied to the fields of medical treatment, sanitation, packaging, agriculture and the like. During production, the nonwoven fabric is typically wound onto a paper or plastic tube by a winding device to form a roll for storage and transport. The traditional non-woven fabric winding device generally adopts a mandrel structure, a paper tube needs to be sleeved outside the mandrel, and winding is realized by means of friction force or simple mechanical fixation. However, in the actual production process, the nonwoven fabric is easy to slide relatively between the paper tube and the mandrel during rapid winding, so that winding is irregular, tightness is uneven, and even the paper tube falls off. In addition, the matching precision requirement of the paper tube and the mandrel is higher, and if the mandrel is worn or the paper tube has deviation in size, the sliding problem can be further aggravated, and the production efficiency and the quality of finished products are affected. Disclosure of utility model The utility model provides a non-woven fabric winding mandrel which can prevent paper tubes from shifting and solves the technical defects. The utility model discloses a non-woven fabric winding mandrel which comprises a shaft barrel, wherein end heads are arranged on end faces of two ends of the shaft barrel, mounting holes penetrating through the shaft barrel are formed in the side faces of two ends of the shaft barrel in the radial direction, rotating shafts are arranged in the mounting holes in a rotating mode, two ends of the rotating shafts are flush with the outer side faces of the shaft barrel, inner hexagonal counter bores are formed in the two ends of the rotating shafts, eccentric wheels are arranged in the middle of the rotating shafts, pistons are arranged in the shaft barrel far away from the end heads in a sliding mode, the eccentric wheels are abutted against the pistons, a bag body is arranged in the shaft barrel between the pistons, liquid is filled in the bag body, two ends of the bag body are abutted against the pistons at the two ends respectively, hollow parts in the length direction of the shaft barrel are uniformly arranged on the periphery of the shaft barrel, supporting pieces are arranged in the hollow parts, and the inner sides of the supporting pieces are fixedly bonded with the bag body. The principle of the technical scheme is that the paper tube is sleeved on the shaft tube, the length of the paper tube is required to be smaller than that of the shaft tube, then the inner hexagonal counter bore on the rotating shaft is screwed by the inner hexagonal wrench, so that the maximum radial point of the eccentric wheel is pressed against the piston, the piston further extrudes the bag body, the bag body bulges to enable the supporting piece to support the paper tube outwards, thereby fixing the paper tube, and when the paper tube needs to be taken down, the rotating shaft is reversely rotated. In order to increase friction, a rubber layer is adhered to the outer side surface of the supporting piece, and the friction force is larger when the rubber layer is contacted with the paper tube, so that the paper tube can be prevented from shifting. In order to limit the axial movement of the rotating shaft, elastic rings are sleeved and fixed at the two ends of the rotating shaft, and the elastic rings are propped against the inner wall of the shaft cylinder. The non-woven fabric winding mandrel has the beneficial effects that the eccentric wheel and the piston can be used for extruding the bag body through screwing the rotating shaft, so that the supporting piece can support the paper tube outwards, the non-woven fabric winding mandrel is simple and efficient, and when the paper tube needs to be taken down, the rotating shaft only needs to be screwed reversely.
