Description

Technical Field

[0001] This utility model relates to the field of packaging paper production technology, and more specifically, it relates to a rewinding mechanism for linen-textured packaging paper. Background Technology

[0002] In the packaging material manufacturing industry, linen-textured packaging paper is widely used for packaging and protecting various commodities due to its unique texture and feel. To meet the personalized needs of different customers, large rolls of packaging paper often require a rewinding process to adjust them to specific lengths and specifications. However, existing rewinding mechanisms have certain limitations in design and function, affecting production efficiency and cost control.

[0003] Firstly, traditional rewinding mechanisms typically mount the paper tube outside the drive shaft as a carrier for the packaging paper. While this method is stable and reliable, each roll of packaging paper requires one paper tube. As production scales up, the consumption of paper tubes increases significantly, leading to higher production costs.

[0004] Secondly, in an effort to reduce costs, some rewinding machines have attempted to omit the paper tube and pre-wrap the packaging paper directly around the drive shaft. However, this method presents a problem: the packaging paper is in direct contact with the drive shaft, and after rewinding, the packaging paper is prone to sticking or rubbing against the drive shaft, leading to difficulties in unloading and even damage to the surface quality of the packaging paper.

[0005] In view of the above problems, there is an urgent need in the market for a new type of rewinding mechanism that can effectively reduce costs and ensure that the packaging paper can be easily and undamaged after rewinding. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides a rewinding mechanism for linen-textured packaging paper to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rewinding mechanism for linen-textured packaging paper, comprising a support frame, a rotating shaft, a drive motor, an air supply component, and a sealing component. The rotating shaft is rotatably mounted on the support frame. One end of the rotating shaft has two sets of clamping components for fixing and rewinding the packaging paper. Each clamping component has a first air bladder for clamping the packaging paper, a second air bladder for supporting the inside of the packaging paper roll, a mounting rod for mounting the first and second air bladders, and a ventilation pipe communicating with the first and second air bladders. The drive motor is mounted on the support frame and connected to the rotating shaft via a coupling, driving the rotating shaft to rotate. The air supply component is used to inflate or extract gas from the ventilation pipe, thereby inflating or deflating the first and second air bladders. The sealing component is installed inside the ventilation pipe and is used to seal the ventilation pipe after the first and second air bladders are inflated.

[0008] The present invention is further configured such that the sealing assembly includes a first sealing seat, a second sealing seat, a receiving rod, a pressure plate, and a fixing plate. The first sealing seat and the fixing plate are both fixedly installed inside the ventilation pipe, and a through hole is provided through the first sealing seat. The second sealing seat is slidably disposed in the through hole. One end of the receiving rod is fixedly connected to the second sealing seat, and the other end slides through the fixing plate and is fixedly connected to the pressure plate. The pressure plate and the fixing plate are respectively provided with a first through groove and a second through groove for gas to pass through. A return spring is provided between the pressure plate and the fixing plate.

[0009] The present invention is further configured such that the air supply assembly includes a tube and a hose, and the tube is connected to the hose, and the tube has an insertion end for connecting to the air supply pipe.

[0010] The present invention is further configured such that the outer diameter of the insertion end is smaller than the inner diameter of the ventilation pipe, and the insertion end is connected to the first through groove of the pressure plate when it extends into the ventilation pipe.

[0011] The present invention is further configured such that the reset spring is sleeved outside the receiving rod.

[0012] The present invention is further configured such that the second sealing seat is provided with a frustum surface, and the through hole in the first sealing seat cooperates with the frustum surface of the second sealing seat.

The rotating shaft 2 is rotatably mounted on the support frame 1. One end of the rotating shaft 2 has two sets of clamping assemblies 21 for fixing and rewinding the packaging paper. Each clamping assembly 21 has a first airbag 211 for clamping the packaging paper, a second airbag 212 for supporting the inside of the packaging paper roll, a mounting rod 213 for mounting the first and second airbags 211 and 212, and a connecting rod for the first and second airbags 211 and 212. A ventilation duct 214 is connected to a support frame 1. A drive motor 3 is mounted on the support frame 1 and connected to the rotating shaft 2 via a coupling. The drive motor 3 drives the rotating shaft 2 to rotate. An air supply assembly 4 is used to inflate or extract air from the ventilation duct 214, thereby inflating or deflating the first airbag 211 and the second airbag 212. A sealing assembly 5 is installed inside the ventilation duct 214 to seal the ventilation duct 214 after the first airbag 211 and the second airbag 212 are inflated. The sealing assembly 5 includes a first sealing seat 51 and a second sealing seat 52. 52. A receiving rod 53, a pressure plate 54, and a fixing plate 55 are included. The first sealing seat 51 and the fixing plate 55 are both fixedly installed inside the ventilation pipe 214. A through hole 56 is provided through the first sealing seat 51. The second sealing seat 52 is slidably disposed in the through hole 56. One end of the receiving rod 53 is fixedly connected to the second sealing seat 52, and the other end slides through the fixing plate 55 and is fixedly connected to the pressure plate 54. The pressure plate 54 and the fixing plate 55 are respectively provided with a first through groove 57 and a second through groove 58 for gas to pass through. A reset mechanism is provided between the pressure plate 54 and the fixing plate 55. Spring 59; the air supply assembly 4 includes a tube 41 and a hose 42, with the tube 41 communicating with the hose 42. The tube 41 has an insertion end 411 for connecting to the air supply pipe 214. The outer diameter of the insertion end 411 is smaller than the inner diameter of the air supply pipe 214, and when the insertion end 411 extends into the air supply pipe 214, the insertion end 411 communicates with the first through groove 57 of the pressure plate 54. The reset spring 59 is sleeved on the outside of the receiving rod 53. The second sealing seat 52 is provided with a frustum surface, and the through hole 56 in the first sealing seat 51 cooperates with the frustum surface of the second sealing seat 52.

[0030] In use, first insert one end of the packaging paper to be rewound between the two sets of clamping components 21, and then insert the insertion end 411 of the insertion tube 41 into the ventilation pipe 214. During insertion, the insertion end 411 will squeeze the pressure plate 54, causing it to move inward together with the receiving rod 53 and the second sealing seat 52, creating a certain gap between the first sealing seat 51 and the second sealing seat 52. At this time, the hose 42 is connected to an air pump or air source, and air is blown inward through the hose 42, causing the first airbag 211 and the second airbag 212 to inflate. The two first airbags 211 of the two sets of clamping components 21 clamp the packaging paper. Then, the insertion tube 41 is pulled out from the ventilation pipe 214, and the return spring 59 rebounds, causing the pressure plate 54 to return to its original position, thereby causing the second sealing seat 52 to re-engage with the first sealing seat 52. The through holes 56 of the seat 51 fit together to seal the ventilation pipe 214. At this time, starting the drive motor 3 can drive the rotating shaft 2 and the two sets of clamping components 21 to rotate simultaneously, thereby rewinding the packaging paper around the two sets of clamping components 21 and wrapping the packaging paper around the two second airbags 212. After the packaging paper is rewound and cut, the insertion tube 41 is inserted into the ventilation pipe 214, and the pressure plate 54 is squeezed again to release the seal in the ventilation pipe 214. At this time, the air is vented out through the hose 42, and the gas in the first airbag 211 and the second airbag 212 is discharged and retracted, so that there is a certain gap between the rewound packaging paper and the first airbag 211 and the second airbag 212. At this time, the rewound packaging paper roll can be easily removed from the two sets of clamping components 21.
