[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model is a PVC plastic film embossing forming device, including an embossing roller, which is composed of a center roller 8 and a plurality of embossing plates 1 with an arc-shaped structure. The embossing plates 1 are arranged on the outside of the center roller 8 and combined to form an embossing tube. One end of the embossing plate 1 is bent toward the end face of the center roller 8 to form a fixed portion 9. Roller shafts 5 are installed at both ends of the center roller 8. A locking mechanism for pressing the fixed portion 9 and positioning the embossing plate 1 is installed on the outside of the roller shaft 5 on one side. A plurality of grooves are provided on the end of the center roller 8 facing the fixed portion 9, and elastic mechanisms for pushing the embossing plate 1 outward are installed in the grooves.

[0023] In this embodiment, the locking mechanism includes an end cover 2 and a sleeve. An arc groove 10 is provided on the outer side of the pressure plate portion. The upper and lower arc grooves 10 are combined to form a positioning groove of an annular structure. The sleeve is installed on the outer side of the end cover 2. The sleeve and the end cover 2 are both sleeved on the roller shaft 5 on one side. A positioning ring 17 is installed on the inner side surface of the end cover 2, and the positioning ring 17 is inserted into the positioning groove.

[0024] In this embodiment, the locking mechanism also includes a grip 3, a screw 16 and a hand-held ball 4. The grip 3 is installed on the outer wall of the sleeve. A first screw hole is provided inside the grip 3, which passes through the grip 3 and the sleeve. A second screw hole 11 is provided on the roller shaft 5 on one side opposite to the first screw hole. The screw 16 is threadedly connected to the first screw hole. One end of the screw 16 is threadedly connected to the second screw hole 11, and the other end extends to the outside and is fixedly connected to the hand-held ball 4.

[0025] In this embodiment, the elastic mechanism includes a push block 15 and a compression spring. The push block 15 is arranged in the opening of the groove. One end of the push block 15 is set to abut against the inner side surface of the fixing part 9. The other end of the push block 15 is fixedly connected to the compression spring. The other end of the compression spring is installed on the inner wall surface of the groove.

[0026] In this embodiment, a slide groove 6 is provided on the roller shaft 5 on one side, and a slider 7 is installed on the inner wall surface of the sleeve facing the slide groove 6. The slider 7 is slidably arranged in the slide groove 6.

[0027] The sleeve and the end cover can be positioned by the slide groove and the slider so that the sleeve and the end cover can only move along the axial direction of the slide groove, thereby avoiding misalignment between the first screw hole and the second screw hole and facilitating the alignment of the screw rod with the second screw hole.

[0028] In this embodiment, a plurality of connecting grooves 14 are axially provided on the outer wall surface of the center roller 8. One end of each connecting groove 14 is expanded outward to form an inlet and outlet 12. Connecting blocks 13 are installed on the inner side surface of the embossed plate 1 facing the connecting grooves 14. The connecting blocks 13 are slidably arranged in the connecting grooves 14.

[0029] The cross-sections of the connecting block 13 and the connecting groove 14 are both arranged in a trapezoidal structure, so that the connecting block and the embossed plate can only move along the axial direction of the connecting groove, thereby increasing the stability of the embossed plate after installation.

[0030] In this embodiment, embossing is provided on the outer side of the embossed plate 1. Different embossing is provided on different embossed plates. Different patterns can be embossed on the PVC plastic film by replacing the embossed plates, thereby increasing adaptability.

[0031] Installation process: Align the connecting block on the embossed plate with the inlet and outlet and move it. After the connecting block enters the inlet and outlet, the inner side of the embossed plate can contact the outer wall of the center roller. After the two embossed plates are installed, you can use the handle to push the sleeve and end cover so that the positioning ring on the end cover is inserted into the positioning groove. The embossed plates can be connected together at one time through the positioning ring and the fixing part is squeezed. The movement of the fixing part drives the embossed plate until the connecting block on the embossed plate slides into the connecting groove, and the inner side of the fixing part contacts the end face of the center roller.

[0032] After the above is completed, the screw is exactly arranged opposite to the second screw hole. The screw can be rotated by holding the ball to make the screw enter the second screw hole, thereby positioning the moved end cover. The end cover can be pressed while positioning the embossed plate. The embossed plate can be axially positioned by the locking mechanism and the fixing part, and the embossed plate can be radially positioned by the connecting groove and the connecting block to ensure the stability of the embossed plate installation.

[0033] Disassembly process: The screw can be rotated in the opposite direction by holding the ball. After the screw is removed from the second screw hole, the push block can be pushed outward by the rebound of the compression spring. The push block moving outward can push the fixing part and the embossed plate. The movement of the embossed plate drives the connecting block, so that the connecting block moves out of the connecting groove and enters the inlet and outlet. At this time, the embossed plate can be directly taken out to facilitate the disassembly of the embossed plate; the embossed plate with different embossing can be quickly installed by disassembly, which increases adaptability.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
