Abstract
Description
Technical Field
[0001] This invention relates to a storage device, and more particularly to a storage device for storing precision PVC film embossing rollers. Background Technology
[0002] A PVC decorative film laminating and embossing machine is a specialized piece of equipment used to laminate PVC film to substrates such as engineered wood panels and cardboard, while simultaneously embossing patterns. Its core process combines heating, pressurizing, and cooling techniques to achieve a strong bond between the decorative film and the substrate, as well as fine processing of the surface texture.
[0003] The core component of an embossing machine is the film embossing roller. When the embossing machine is working, it mainly uses the rolling of the film embossing roller to emboss patterns on the substrate.
[0004] As people's requirements for the exquisiteness and texture of substrate patterns continue to increase, the precision of film embossing rollers is constantly improving. In order to be able to emboss a variety of textures and patterns, current embossing machines are equipped with a large number of film embossing rollers. These film embossing rollers are assembled into the embossing machine for production according to production needs. However, idle film embossing rollers are usually placed on the wheel frame.
[0005] like Figure 1 As shown, due to the large weight of the precision PVC film embossing roller, placing it on the wheel frame will inevitably cause it to bend due to its own weight after a long period of time. Once the embossing wheel bends, a bending arc will form on its working outer surface, which will seriously affect the precision of the embossing roller. In severe cases, it will lead to the scrapping of a large number of embossing rollers, which is the main drawback of the existing technology. Summary of the Invention
[0006] The technical solution adopted in this invention is: a storage device for a precision PVC film embossing roller, which is used to accommodate a precision PVC film embossing roller in a non-working state. The embossing roller includes a roller body and a roller body shaft, wherein the roller body shaft is respectively disposed at both ends of the roller body, and the roller body shaft is provided with an assembly groove.
[0007] The storage device includes an active part and a driven part. The shafts of the embossing roller at both ends are respectively inserted into the active part and the driven part. The active part drives the embossing roller to rotate, so that the embossing roller can rotate along its own axis when it is not in operation. The active part drives the embossing roller to rotate, so that the embossing roller rotates at an idle speed.
[0008] The beneficial effects of this invention are as follows: The design concept of this invention is that when the embossing roller is in a non-working state, it is placed in the storage device. The storage device drives the embossing roller so that it can still rotate along its own axis when not in working state, thereby simulating the working conditions of the embossing roller in working state, so that the weight of each part of the roller is balanced, thus avoiding local deformation of the roller and preventing physical deformation of the roller after long-term storage. The storage device of this invention is mainly used to store some precision PVC film embossing rollers. Other ordinary embossing rollers can be stored in the traditional way.

[0021] like Figures 2 to 12As shown, a storage device 100 for a precision PVC film embossing roller is provided. The storage device 100 is used to hold a precision PVC film embossing roller 10 in a non-working state. The embossing roller 10 includes a roller body 11 and a roller body rotating shaft 12. The roller body rotating shaft 12 is respectively disposed at both ends of the roller body 11. The roller body rotating shaft 12 is provided with an assembly groove 13. The outer surface of the roller body 11 is provided with an embossing pattern. When in use, the embossing roller 10 is assembled in an embossing machine through the assembly groove 13. The embossing machine drives the embossing roller 10 to rotate through the roller body rotating shaft 12, and uses the embossing pattern of the roller body 11 to press a pattern on the PVC film.
[0022] The storage device 100 includes an active part 110 and a driven part 120. The shafts 12 of the embossing roller 10 at both ends are respectively inserted into the active part 110 and the driven part 120. The active part 110 drives the embossing roller 10 to rotate, so that the embossing roller 10 can rotate along its own axis when not in operation. The active part 110 drives the embossing roller 10 to rotate at an idle speed. In practice, this idle speed is lower than the speed of the embossing roller 10 when it is in operation, specifically less than one-third of the speed of the embossing roller 10 when it is in operation. The design concept of this invention is that when the embossing roller 10 is in a non-working state, it is placed in the storage device 100. The storage device 100 drives the embossing roller 10 so that it can still rotate along its own axis when not in working state, thereby simulating the working conditions of the embossing roller 10 in working state. This ensures that the weight of each part of the roller 11 is balanced, so as to avoid local deformation of the roller 11 and prevent physical deformation of the roller 11 after long-term storage. The storage device 100 of this invention is mainly used to store some precision PVC film embossing rollers 10. Other ordinary embossing rollers can be stored in the traditional way.
[0023] The active part 110 includes a surrounding rolling gear system 200 and a drive gear 300. The central axis 201 of the surrounding rolling gear system 200 coincides with the central axis 301 of the drive gear 300. The surrounding rolling gear system 200 includes several rotating wheels 210. The drive gear 300 drives the surrounding rolling gear system 200 to rotate as a whole around the central axis 201 of the gear system in a first direction T1. Several rotating wheels 210 are arranged around the rotating shaft 12 of the rod body, and each rotating wheel 210 is rolled and pressed in the mounting groove 13.
[0024] When the surrounding rolling wheel system 200 rotates in the first direction T1, the drive gear 300 simultaneously drives several of the rotating wheels 210 to rotate, so that each of the rotating wheels 210 rotates in the second direction T2 about its own central axis 211. These rotating wheels 210 simultaneously drive the rod shaft 12, so that the rod shaft 12 rotates in the third direction T3 about its own axis 14. In practice, the first direction T1 and the third direction T3 are the same direction of rotation. The first direction T1 and the third direction T3 rotate in opposite directions to the second direction T2. This invention drives the embossing roller 10 through the aforementioned structural design, enabling the roller 10 to rotate along its own axis even when not in operation. This simulates the working conditions of the roller 10 during operation, ensuring balanced gravity across all parts of the roller 11 and preventing localized deformation that could lead to physical deformation over time.
[0025] In practical implementation, the rotating wheel 210 is made of an elastic material, such as silicone or rubber. Each rotating wheel 210 is fitted onto a sub-rotating shaft 400. The sub-rotating shaft 400 includes a limiting protrusion 410, a fitting part 420, a meshing part 430, a limiting disc 440, and a pivot 450.

An end cap 411 is fitted on the limiting protrusion 410. The end cap 411 can limit the depth of the embossing rod 10 inserted into the active part 110.
[0027] The limiting plate 440 is disposed between the meshing part 430 and the pivot 450. The limiting plate 440 is provided with a convex ring rib 441, which corresponds to the wheel side of the drive gear 300. The convex ring rib 441 can limit the lateral position of the drive gear 300 and prevent the drive gear 300 from colliding with other components.
[0028] The pivot 450 is fitted with a bearing 451. The active part 110 also includes a structural disk 500, which has a groove 510. The bearing 451 on the pivot 450 of each sub-shaft 400 is rolled in the groove 510. The active gear 300 is fitted on the gear shaft 310, which is inserted into the central bearing 320. The central bearing 320 is fixedly located in the center of the structural disk 500, and the groove 510 is arranged around the central bearing 320.
[0029] In a specific implementation, the structural disk 500 is fixedly connected to the frame 20 by several connecting ribs 520. The present invention can connect the surrounding rolling wheel system 200 and the driving gear 300 to the frame 20 through the structural disk 500. In a specific implementation, the gear shaft 310 is connected to the power output shaft of the motor through the coupling 21, and the motor can drive the gear shaft 310 and the driving gear 300 to rotate.

Each driven rotating wheel 210B is rolled and pressed in the mounting groove 13.
[0031] In practical implementation, the driven wheel 210B is made of an elastic material, such as silicone or rubber. Each driven wheel 210B is fitted onto the driven shaft 400B. The driven shaft 400B includes a limiting protrusion 410B, a fitting part 420B, a limiting disc 440B, and a pivot 450B. The driven wheel 210B is fitted onto the fitting part 420B.
[0032] The limiting protrusion 410B protrudes from the end of the fitting part 420B on one side of the driven shaft 400B. The limiting protrusion 410B corresponds to the end side of the other side of the rod body 11. An end cap 411B is fitted on the limiting protrusion 410B. The end cap 411B can limit the depth of the embossing rod 10 inserted into the driven part 120. A protruding ring rib 441B is provided on the limiting disc 440B. A bearing 451B is fitted on the pivot 450B.
[0033] The driven part 120 also includes a driven structure disk 500B, which is provided with a roller groove 510B. The bearing 451B on the pivot 450B of each driven sub-shaft 400B is rotatably disposed in the roller groove 510B. In specific implementation, the driven structure disk 500B is fixedly connected to the frame 20 by several connecting ribs 520B. The present invention can connect the driven surrounding rolling wheel system 200B to the frame 20 through the driven structure disk 500B.

When the surrounding rolling wheel system 200 rotates in the first direction T1, the driving gear 300 simultaneously drives several of the rotating wheels 210 to rotate, so that each of the rotating wheels 210 rotates in the second direction T2 with its own rotating wheel central axis 211. Several of the rotating wheels 210 simultaneously drive the rotating shaft 12 of the rod body, so that the rotating shaft 12 of the rod body rotates in the third direction T3 with its own rotating shaft axis 14.
