The two limit guide rods 11 are arranged at intervals in the X-axis direction. The first sliding seat 2 and the second sliding seat 3 are arranged between the two limit guide rods 11. With this structure, the first sliding seat 2 and the second sliding seat 3 can be respectively resisted and limited by the two limit guide rods 11, so that the first sliding seat 2 and the second sliding seat 3 can be limited at the positions between the two limit guide rods 11.

[0046] In one embodiment, please refer to Figure 1 , a first handle 27 is installed on the first sliding seat 2, and the first handle 27 facilitates the operator to pull the first sliding seat 2. A second handle 33 is installed on the second sliding seat 3, and the second handle 33 facilitates the operator to pull the second sliding seat 3.

[0047] In one embodiment, please refer to Figure 2 , the roller shaft support structure further includes a lock 12. The locking part of the lock 12 can be installed on the first sliding seat 2, and the hanging part of the lock 12 can be installed on the second sliding seat 3. With this structure, the first sliding seat 2 and the second sliding seat 3 can be locked and fixed by the lock 12, improving the locking ability between the first sliding seat 2 and the second sliding seat 3.

[0048] In some embodiments, a semi-circular groove portion for one end of the shaft sleeve 10 to extend into is provided on the inner side wall of the first opening 23, and a semi-circular groove portion for the other end of the shaft sleeve 10 to extend into is provided on the inner side wall of the second opening 32. With this structure, the shaft sleeve 10 can be clamped and fixed through the first opening 23 and the second opening 32.

[0049] The embodiment of the present application also provides a laminator, which includes a machine shell and the roller shaft support structure provided in any of the above embodiments. The installation guide rail 1 is installed on the machine shell. Among them, the installation guide rail 1 can be installed on the machine shell through fasteners such as screws and bolts, so that the detachable installation of the installation guide rail 1 can be realized, and then the overall disassembly, assembly and maintenance of the roller shaft support structure are facilitated. With this structure, the first sliding seat 2 and the second sliding seat 3 are respectively slidably installed on the installation guide rail 1. A positioning clamping seat 31 is installed on the second sliding seat 3, and a sliding clamping seat 21 and a sliding driving member 22 are respectively installed on the first sliding seat 2. When the sliding driving member 22 drives the sliding clamping seat 21 to move and engage with the positioning clamping seat 31, the first sliding seat 2 and the second sliding seat 3 approach and lock, and the roller shaft is supported through the first opening 23 and the second opening 32; when the sliding driving member 22 drives the sliding clamping seat 21 to move and unlocks it from the positioning clamping seat 31, the first sliding seat 2 and the second sliding seat 3 move away and unlock, so that the roller shaft can be taken out from the area surrounded by the first opening 23 and the second opening 32, which is convenient for the disassembly and assembly of the roller shaft. The laminator adopting the roller shaft support structure can realize the rapid disassembly and assembly of the roller shaft, thereby improving the operation efficiency of the unwinding roll or the rewinding roll.

[0050] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
