[0002] In the film production process (such as copper film), a roller assembly is required to tension the film, and at the same time, it also plays a role in conveying the film under the action of traction. In the prior art, the roller is generally connected to the installation base through a connecting structure set at both ends. The installation base is a frame. Usually, the connecting structure generally includes a mounting plate connected to the end of the roller and a mounting shaft connected to the frame.

[0023] In an exemplary embodiment, Figure 1-4 As shown, this embodiment provides a roller connection structure, which is installed on a frame. The frame includes a pair of mounting seats 1, and the connection structure includes mounting shafts 2 respectively connected to the two mounting seats 1, and mounting rings 3 respectively detachably connected to the two mounting shafts 2, and mounting plates 5 respectively detachably connected to the two ends of a roller 4, and telescopic connectors 6 respectively detachably connected to the two mounting rings 3, the telescopic connectors 6 are located between adjacent mounting rings 3 and mounting plates 5, and the mounting plates 5 can be relatively telescopic and locked with the telescopic connectors 6.

[0024] In the above embodiment, the mounting ring 3 is connected to the mounting shaft 2, the mounting disk 5 is connected to the end of the roller 4, and a telescopic connector 6 is provided between the mounting ring 3 and the mounting disk 5. The telescopic connector 6 and the mounting disk 5 can have a one-to-many (such as a one-to-two in the present embodiment) connection relationship, so that the present structure can provide connection for at least two lengths of rollers 4, simplifying the installation steps, thereby solving the problem in the prior art that there is a one-to-one correspondence between rollers 4 of different lengths and the connection structure, resulting in a more complicated replacement process; specifically, during installation, it is only necessary to disassemble the mounting disk 5 and the roller 4, then loosen the mounting disk 5 and the telescopic connector 6, adjust the position, replace with another roller 4, and reinstall it.

[0025] like Figure 1-4 As shown, in a specific exemplary embodiment, the telescopic connector 6 includes a connecting tube 7, one end of which is connected to the mounting ring 3 and the mounting shaft 2 through a first connecting member 8, and the other end is provided with a telescopic hole 9 and at least two connecting holes 10 vertically connected to the telescopic hole 9 are also provided on its wall surface, the mounting plate 5 is also fixedly connected to a telescopic shaft 11 and the telescopic shaft 11 is provided with at least two docking holes that can dock with the connecting hole 10, and a second connecting member 12 is provided between the connecting hole 10 and the docking hole docking therewith. The telescopic setting is realized by the telescopic shaft 11 and the connecting tube 7, that is, the connecting tube 7 is connected to the mounting ring 3, and the telescopic shaft 11 is fixedly connected to the mounting plate 5. The different degrees of the telescopic shaft 11 extending into the telescopic hole 9 can adjust the distance between the two mounting plates 5. After the adjustment, it can be locked by the second connecting member 12. More specifically, the connecting hole 10 includes at least two pairs symmetrically arranged on both sides of the telescopic hole 9, the docking hole is a through hole, and the second connecting member 12 is a long rod bolt that penetrates the docking hole and the corresponding two connecting holes 10. The two ends of the long rod screw are located on both sides of the connecting tube 7, and then the installation is realized by locking the nut. When disassembling, the nut can be removed to pull out the long rod bolt, and then the telescopic shaft 11 can be adjusted;

[0026] Furthermore, a short-rod bolt may be screwed into another connecting hole 10 (not connected with a long-rod bolt) to seal the hole and prevent external impurities from entering.

[0027] like Figure 1-4 As shown, further exemplary, a first mounting groove 13 is provided on the outer wall of the connecting tube 7 along the axial direction thereof, and the second connecting member 12 is located in the first mounting groove 13, so that the long-rod bolt structure (short-rod bolts are also included in the above) cannot be seen outside the connecting tube 7. Similarly, a second mounting groove 14 is provided on the outer wall of the connecting tube 7 along the axial direction thereof, and the first connecting member 8 is located in the second mounting groove 14, so that the first connecting member 8 is also prevented from being seen from the outside;

[0028] In more detail, a flared hole is provided at one end of the connecting tube 7 away from the telescopic hole 9, and the mounting ring 3 is accommodated in the flared hole. The first connecting member 8 includes a short rod bolt connected to the outer wall of the connecting tube 7 and the mounting ring 3. After the short rod bolt is unloaded, the telescopic connector 6 can be removed. Furthermore, the flared hole and the telescopic hole 9 are arranged coaxially and the two are connected, so that a longer space is left in the axial direction of the connecting tube 7, which is convenient for removing or installing the roller 4.

[0029] like Figure 1-4 As shown, in a further exemplary embodiment, the mounting plate 5 is sleeved on the end of the roller 4 and connected to the roller 4 through a third connecting member 15. Similar third connecting member 15 can also be a short-rod bolt.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
