[0024] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0025] Reference Figures 1 to 3 As shown, a tension adjustment device for an interlocking armoring machine is provided, comprising a cylinder seat 1, a push plate 2 is mounted on one side of the cylinder seat 1, a cylinder 3 for controlling the push plate 2 to move back and forth is symmetrically mounted on the other side of the cylinder seat 1, a bearing 4 is mounted on the push plate 2, the bearing 4 is connected to a rotatable three-claw connecting plate 5, the three-claw connecting plate 5 extends outwardly with three claws 51, and brake assemblies 6 are fixedly mounted on the three claws 51.

[0026] In this embodiment, the push plate 2 is controlled to move forward or backward by the cylinder 3, and the tension of the tape is observed according to the actual situation. If the tape tension is insufficient, the cylinder 3 pushes the push plate 2 forward, and the brake assembly 6 arranged on the three-claw connecting plate 5 pushes the tape to increase the tape tension. If the tape tension is too tight, the cylinder 3 can be properly adjusted to make the push plate 2 retreat so that the tape is at a position with appropriate tension. The bearing 4 mainly plays a buffering role to avoid mutual wear between the tape and the brake assembly 6, which affects the product quality.

[0027] In one embodiment of the utility model, the brake assembly 6 is composed of a brake flange seat 61 and a brake rod 62. The brake flange seat 61 is fixedly mounted on the claw portion 51 of the three-claw connecting plate 5. The brake rod 62 is inserted into the brake flange seat 61, and the top of the brake rod 62 is clamped on the outer surface of the top end of the brake flange seat 61. Preferably, a brake pad is fixedly mounted on the top of the brake rod 62.

[0028] Furthermore, in order to prevent the brake flange seat 61 from rotating during operation, a limit seat 7 is arranged at the bottom of the brake flange seat 61, and a locking portion 71 is arranged on the limit seat 7. A limit groove 611 cooperating with the locking portion 71 is opened at the bottom of the brake flange seat 61. The limit seat 7 is fixedly installed on the claw portion 51 of the three-claw connecting plate 5 by screw connection, and the locking portion 71 of the limit seat 7 is inserted into the limit groove 611 of the brake flange seat 61. The limit seat 7 is fixedly connected to the brake rod 62 by screws, so that the brake rod 62 cannot rotate during operation, and the entire three-claw connecting plate 5 can only be rotated through the bearing 4.

[0029] In one embodiment of the utility model, a sliding rod 21 is fixedly connected to one side of the push plate 2 close to the cylinder 3. The sliding rod 21 is used to be inserted into the flange-type linear bearing 8 to facilitate the directional movement of the push plate 2. The flange-type linear bearing 8 is connected to the side of the cylinder seat 1 close to the cylinder 3 by screws. The sliding rod 21 is inserted into the flange-type linear bearing 8. The sliding rod 21 slides back and forth in the flange-type linear bearing 8 by controlling the cylinder 3.

[0030] Preferably, the three-claw portions 51 are evenly distributed on the periphery of the three-claw connecting plate 5, so that the force exerted on the unwinding tape is evenly distributed.

[0031] In one embodiment of the utility model, in order to adjust the unwinding tension more conveniently and accurately without stopping the machine, the cylinder 3 is connected to an external precision digital pressure regulating valve or a touch screen for inputting the displacement data of the push plate 2, so that the unwinding tension can be adjusted quickly and conveniently.

[0032] In one embodiment of the utility model, a bearing seat 9 is installed on one side of the cylinder seat 1 close to the cylinder 3. Since the available space of the armoring machine is limited, the bearing seat 9 can be easily installed on some original installation surfaces of the armoring machine. After installation, pneumatic operation can be realized, and the tension of the tape can be adjusted more conveniently and accurately.

[0033] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
