[0002] The rewinding and inspection machine is mainly used to rewind the paper rolls (called base paper rolls) produced by the papermaking machine, and to inspect the paper in the process to ensure the quality of the paper. The rewound paper can be made into finished paper for shipment. It is suitable for inspection and rewinding of printed products in the flexible packaging industry, and is also suitable for material rewinding or inspection operations in the plastics, printing, laminating, coating, bag making, coating and other industries.

[0003] The working principle of the rewinding and inspection machine mainly involves two processes: paper rewinding and inspection. During the rewinding process, the machine unwinds, trims, slits, splices and rewinds the original paper roll to form a finished paper roll with certain specifications and tightness requirements.

[0038] The storage chamber 4 is fixedly mounted on the top of the support base 27 away from the support top frame 30, the displacement cross frame 15 is fixedly mounted between the two connecting extension frames 23, the side end of the connecting side plate 21 close to the first gear 26 is connected to the front of the side end of the support base 27, the first gear 26 is rotatably mounted on both sides of the support base 27 close to the sponge wheel 28, the second gear 32 is vertically aligned with the first gear 26, the tooth distribution angle of the second gear 32 is 180°, the worm wheel 36 is meshed with the worm 33, and the cam 35 is engaged with the round wheel 8 is vertically aligned, a card key is fixedly installed on the side end of the displacement cross frame 15 away from the second spring 18, and card slots are opened on both sides of the inner part of the support base 27 near the lighting lamp 31, and movable slots are opened on both sides of the inner part of the support base 27 near the lighting lamp 31, and the movable slots are located above the card slots, both sides of the bottom of the contact bottom plate 19 are inclined at 45°, the top of the contact top plate 16 is flush with the bottom end of the visual detector 29, and a dripping hole is opened at the bottom end of the storage cavity 4, and the dripping hole is vertically aligned with the sealed rubber plug 11.

[0039] The working principle of embodiment 1 is as follows: when in use, the paper on the external paper roll is first wound around the roller 3, and then the external winding device can be installed on the top of the support base 27 away from the support top frame 30, so that the winding device can wind the paper and move it on the roller 3. When the paper moves on the roller 3, it can first pass through the top front end of the support base 27. When the paper enters above the illuminating lamp 31, the light can shine on the bottom end of the paper, so that the texture inside the paper can be revealed, and the visual detector 29 is located directly above the illuminating lamp 31, so that the texture revealed on the paper can be observed, which is convenient for detecting whether there are large stains and impurities inside the paper, thereby improving the quality of the paper. Then, when the paper passes the bottom end of the sponge wheel 28, through The sponge wheel 28 is in contact with the surface of the paper, and one end of the worm 33 away from the sponge wheel 28 is connected to an external driving motor. When the driving motor is started, the sponge wheel 28 can be driven to rotate. The sponge wheel 28 is in contact with the surface of the paper, and when the sponge wheel 28 rotates, the broken fibers attached to the surface of the paper can be removed. At the same time, the inside of the sponge wheel 28 is in a slightly moist state, so that the disinfectant can be attached to the surface of the paper. At the same time, when the sponge wheel 28 rotates, the worm 33 and the worm wheel 36 can be driven to rotate at the same time, and when the worm wheel 36 rotates, the cam 35 can be driven to rotate, so that when the raised part of the cam 35 rotates to fit the round wheel 8, the round wheel 8 and the alignment top plate 6 can be squeezed to move upward at the same time, and the alignment top plate 6 is slidably sleeved on the guide vertical plate. 7, so that the round wheel 8 can be ensured to move up and down in a straight line. When the alignment top plate 6 moves upward, the sealing rubber plug 11 can be driven by the connecting rod 5 to move out from the dripping hole at the bottom of the storage cavity 4, so that the disinfectant inside the storage cavity 4 can fall into the inside of the sponge wheel 28 through the dripping hole, thereby controlling the wetness inside the sponge wheel 28, making it easier for the sponge wheel 28 to attach the disinfectant to the surface of the paper. Subsequently, when the raised part of the cam 35 rotates and passes the round wheel 8, the elasticity of the first spring 10 will drive the alignment top plate 6 and the round wheel 8 to quickly reset downward, so that the sealing rubber plug 11 can close the dripping hole at the bottom of the storage cavity 4, avoiding excessive flow of disinfectant into the inside of the sponge wheel 28, and preventing the sponge wheel 28 from being over-wet, completing the paper disinfection. The sponge wheel 28 rotates, and the second gear 32 rotates at the same time. When the teeth of the second gear 32 rotate to contact the first gear 26, the first gear 26 and the winding wheel 25 rotate at the same time. When the winding wheel 25 rotates, the connecting extension frame 23 can be pulled to move to the rear end by the connecting rope 24. The connecting extension frame 23 is fixedly installed between the two connecting extension frames 23 through the displacement cross frame 15, and the connecting extension frame 23 can move in the movable groove inside the supporting base 27, so that the displacement cross frame 15 can be displaced in a straight line. When the displacement cross frame 15 moves, the contact top plate 16 and the contact bottom plate 19 can be driven to contact the bottom end of the visual detector 29 and the top surface of the illuminating lamp 31 respectively. Moreover, when the displacement cross frame 15 continues to move,The contact top plate 16 and the contact bottom plate 19 can be driven to pass through the visual detector 29 and the illuminating lamp 31, so that the broken fibers attached to the bottom of the visual detector 29 and the top of the illuminating lamp 31 can be scraped off. Then, when the part with teeth of the second gear 32 rotates through the first gear 26, the first gear 26 will lose the meshing force. At this time, the elasticity of the third spring 22 will drive the connecting extension frame 23 to reset, so that the contact top plate 16 and the contact bottom plate 19 can pass through the visual detector 29 and the illuminating lamp 31 again, and the visual detector 29 and the illuminating lamp 31 can be cleaned again. Moreover, when the connecting extension frame 23 is reset, the winding wheel 25 can be pulled by the connecting rope 24 to rotate and reset, so that the second gear 32 can drive the first gear 26 to rotate again to complete the work.

[0040] Example 2

[0041] On the basis of Example 1, Figure 8 As shown, the support base 27 also includes a positioning top frame 38, a hydraulic cylinder 39 and a contact wheel 40. The positioning top frame 38 is fixedly mounted at the top rear end of the support base 27, the hydraulic cylinder 39 is symmetrically fixedly mounted on the positioning top frame 38, and the contact wheel 40 is fixedly mounted at the bottom end of the hydraulic cylinder 39.

[0042] When implementing this embodiment, when the paper becomes loose while being transmitted on the roller 3, the hydraulic cylinder 39 can be started to drive the contact wheel 40 to move downward until it contacts the paper, thereby squeezing the paper downward, so that the paper can be tensioned to prevent the paper from becoming loose. In addition, by starting the hydraulic cylinder 39 to drive the contact wheel 40 to move downward to a specified height, the squeezing force on the paper can be adjusted to facilitate tensioning of paper with different degrees of looseness.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
