Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 2, the PVC film for water-based ink comprises a PVC film wound on a core 1, the core 1 is made of paper material, and is environmentally friendly and low in cost.

The PVC film is a high-temperature laminating film.

The inner core 1 of this embodiment is a cylinder, and it is a commercial product, and the annular groove 10 is respectively arranged at both ends of the inner wall of the inner core 1, specifically, the inner step is arranged at both ends of the inner wall of the inner core 1, and the stop ring is arranged at the outer end of the inner step, and the stop ring and the inner step form the above-mentioned annular groove 10.

The barrier ring is the ring of paper material, and it is fixed on the step including through the viscose, and secondly, it can be convenient for to the metal axle sleeve of packing into in the ring channel to and the circumferential position adjustment of the metal bearing of being convenient for of this kind of design.

The inner diameter of the blocking ring is equal to the inner diameter of the inner core 1. And interference of the mandrel inserted in the metal shaft sleeve is prevented.

And metal shaft sleeves 2 which are fixedly connected with the circumferential direction of the annular grooves 10 are respectively arranged in each annular groove 10, a threaded hole is formed in the outer wall of each metal shaft sleeve 2, and screws 11 which are in threaded connection with the threaded holes are arranged at two ends of the inner core 1 in a penetrating manner. The screw 11 is a countersunk head screw to prevent the cap from bulging and injuring the operator.

The circumference is fixed and can prevent the free rotation of the inner core circumference relatively due to the stress of the metal shaft sleeve, and the subsequent winding processing of the PVC film can not be met.

The axial lead coincidence of two metal axle sleeves 2 and the internal diameter of metal axle sleeve 2 is less than the internal diameter of inner core 1, and the internal diameter is little, can match with the dabber on the coiling equipment, in order to avoid dabber and inner core contact and damage the inner core, the inner core just also can't be used repeatedly, promptly, the dabber penetrates to the metal axle sleeve, and it can form the alignment to a certain extent to the inner core with the contact of dabber of two metal axle sleeves, just also can ensure the alignment of the interior outer layer after the PVC membrane is convoluteed, has improved the coiling quality.

Next, as shown in fig. 3, an adhesive sheet 12 is provided in the length direction of the core 1, and the length of the adhesive sheet 12 is shorter than the width of the PVC film, so as to prevent external dust from sticking to the PVC film due to the excessive length of the adhesive sheet 12 during subsequent transportation, which may affect the quality, and the inner end of the PVC film is stuck by the adhesive sheet 12. The adhesive sheet is, for example, a sheet with adhesive, and the thickness of the sheet is less than 0.1mm to ensure the roundness of the winding.

The sheet body is a plastic sheet, and the viscose is a commercial product.

As shown in fig. 4, the PVC film includes a PVC base film 30, a PVC top film 31, and a water-based ink layer 32, and the water-based ink layer 32 is located between the PVC base film 30 and the PVC top film 31. The PVC base film 30 and the PVC face film 31 are both transparent PVC film materials.

PVC basement membrane 30, PVC facial mask 31 and waterborne printing ink layer 32 form through the hot pressing pressfitting, through the waterborne printing ink layer 32 of designing in this embodiment, and it can improve the grade of PVC membrane, just also can improve the income of enterprise, and simultaneously, it can be directly diluted with water on the waterborne printing ink layer, and the batching is convenient more and simple.

During winding, the inner core 1 is sleeved on a mandrel of a winding device, namely, the metal shaft sleeve is contacted with the mandrel;

and adhering the inner end of the PVC film on the adhesive sheet 12, then starting a winding device to wind, finishing winding and cutting, and repeating the actions.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
