Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3 , the present utility model discloses a PVC protective film laminating roller, including a U-shaped frame 1. A bidirectional screw 101 is movably arranged inside the U-shaped frame 1, and a guide rod 107 is fixedly arranged inside the U-shaped frame 1. Opposite threads are symmetrically arranged on both sides of the bidirectional screw 101. One end of the bidirectional screw 101 penetrates through the inside of the U-shaped frame 1 and extends to the outside of the U-shaped frame 1. A locking disc 2 is fixedly arranged at one end of the bidirectional screw 101, and a locking groove is opened at the top of the locking disc 2. A locking device 3 is arranged above the locking disc 2;

[0022] A locking rod 301 is movably arranged inside the locking device 3. One end of the locking rod 301 is located in the locking groove at the top of the locking disc 2. The other end of the locking rod 301 is fixedly provided with a fixing plate 302. A fixing rod 304 is fixedly arranged at the top of the fixing plate 302. A return spring 303 is sleeved on the surface of the fixing rod 304. One end of the fixing rod 304 penetrates through the inside of the locking device 3 and extends to the outside of the locking device 3. A pull ring 305 is fixedly arranged at one end of the fixing rod 304. An installation plate 4 is fixedly arranged on one side of the locking device 3.

[0023] Specifically, a handle 106 is fixedly arranged at one end of the bidirectional screw 101. Hanging plates 102 are movably arranged on both sides of the surface of the bidirectional screw 101. Threaded holes adapted to the bidirectional screw 101 are opened on the inner sides of the hanging plates 102. The connection relationship between the bidirectional screw 101 and the hanging plates 102 is a threaded connection.

[0024] In this implementation scheme, by setting the handle 106, the bidirectional screw 101 and the hanging plate 102, the bidirectional screw 101 is driven to rotate by rotating the handle 106. The rotating bidirectional screw 101 drives the hanging plates 102 on both sides to move. When the distance between the two hanging plates 102 is enlarged, the tube 105 can be disengaged.

[0025] Specifically, a bearing 103 is fixedly arranged on one side of the hanging plate 102, a support shaft 104 is arranged on one side of the bearing 103, and a tube 105 is arranged at one end of the support shaft 104.

[0026] In this implementation scheme, by setting the tube 105, the PVC protective film on the tube 105 is unfolded and attached to the surface of the thin aluminum plate, thereby realizing film pasting.

[0027] Specifically, the mounting plate 4 and the U-shaped frame 1 are movably connected by bolts 5, and a threaded hole adapted to the bolt 5 is opened on one side of the top of the U-shaped frame 1.

[0028] In this implementation scheme, by setting the bolt 5, the mounting plate 4 on one side of the locking device 3 is placed on one side of the top of the U-shaped frame 1, and then the bolt 5 is inserted and screwed. When one end of the bolt 5 is screwed into the threaded hole on the U-shaped frame 1, the installation of the locking device 3 can be realized.

[0029] Specifically, connecting seats 6 are fixedly arranged on both sides of the back of the U-shaped frame 1, and mounting holes are opened on the surfaces of the connecting seats 6.

[0030] In this implementation scheme, by setting the connecting seats 6, the connecting seats 6 are installed at the required positions by screws, thereby completing the fixation of the position of the U-shaped frame 1.

[0031] Specifically, the connection relationship between the locking disc 2 and the locking rod 301 is movable plug-in connection.

[0032] In this implementation scheme, by setting the locking rod 301, the locking rod 301 is moved by pulling the pull ring 305. When one end of the locking rod 301 is removed from the locking hole on the locking disc 2, the locking of the bidirectional screw 101 and the handle 106 can be released, and then the handle 106 can be operated.

[0033] During use, the mounting plate 4 on one side of the locking device 3 is placed on one side of the top of the U-shaped frame 1, and then the bolt 5 is inserted and screwed. When one end of the bolt 5 is screwed into the threaded hole on the U-shaped frame 1, the installation of the locking device 3 can be realized;

[0034] When installing the tube 105, the locking rod 301 is temporarily in a telescopic state by pulling the pull ring 305. Then, the tube 105 is placed between the two hanging plates 102. Then, the bidirectional screw 101 is rotated by turning the handle 106. The rotating bidirectional screw 101 drives the two hanging plates 102 to move. When the distance between the two hanging plates 102 is reduced, the installation of the tube 105 can be achieved.

[0035] When locking the bidirectional screw 101 and the handle 106, the pull ring 305 is released, and the restoring force of the return spring 303 causes the locking rod 301 to move back. When one end of the locking rod 301 is inserted into the locking hole on the locking disc 2, the bidirectional screw 101 and the handle 106 can be locked.

[0036] When unlocking the bidirectional screw 101 and the handle 106, the locking rod 301 is moved by pulling the pull ring 305. When one end of the locking rod 301 is removed from the locking hole on the locking disc 2, the locking of the bidirectional screw 101 and the handle 106 can be released, and then the handle 106 can be operated.

[0037] When disassembling the tube 105, the bidirectional screw 101 is rotated by turning the handle 106. The rotating bidirectional screw 101 drives the two hanging plates 102 to move. When the distance between the two hanging plates 102 is increased, the tube 105 can be disengaged.

[0038] In summary, for this PVC protective film laminating roller, by setting the locking disc 2 and the locking rod 301, after the installation of the tube 105 is completed, the pull ring 305 is released, and the restoring force of the return spring 303 causes the locking rod 301 to move back. When one end of the locking rod 301 is inserted into the locking hole on the locking disc 2, the bidirectional screw 101 and the handle 106 can be locked, effectively restricting the movement of the handle 106 and preventing the handle 106 on the bidirectional screw 101 from being accidentally collided and causing the bidirectional screw 101 to rotate accidentally, thereby improving the stability of the installation of the tube 105.
