Action process and working principle of the invention:
In conjunction with Fig. 1, the present invention is installed.After being installed, by rotating adjusting nut, the height of upper supporting roller is adjusted
Degree, makes upper supporting roller be covered in the lower surface of transmission belt, and guarantee the planarization of transmission belt in the transmit direction；Pass through spacer
The thickness of plate adjusts the floating elastic intensity of upper supporting roller.When transmission belt is normally carried out transmission, upper rotation brake beam 2 is put in level
It sets.
Upper supporting roller of the invention is close to the lower section of process adhesive tape always, judges whether to disconnected band by the tension of adhesive tape
It arrests.When normal transmission, upper rotation brake beam 2 in horizontal positioned, the process adhesive tape of conveyer since tension covers on upper supporting roller,
Rotation brake beam 2 and weight linear meter 6 is avoided to be rotated, upper rotation brake beam 2 lock is pressed in crank body 8 at this time, avoids down arresting
Mechanism starting, and the length direction of tension spring 10, along the length direction of weight linear meter 6, tension spring 10 does not generate torsion to weight linear meter 6
Power.The upper surface of upper transmission belt is in groove profile and is placed with material, is transmitted.
When disconnected band occurs for adhesive tape, the tension of the defeated band of process can rapidly disappear, and upper rotation brake beam 2 is under the action of weight linear meter 6
It rotates to choose on rapidly and flatten process adhesive tape and bullet flies into material on journey glue band, weight linear meter 6 and the progress of upper rotation brake beam 2
After rotation, the length direction of the length direction and weight linear meter 6 of tension spring 10 is inconsistent, and tension spring 10 provides driving counterweight to weight linear meter 6
Bar 6 carries out the pulling force of accelerating torque, and upper rotation brake beam 2 accelerates rotation, and fixed brake beam 5 is close upwards, clamps and arrests roller 4 and upper
Arc is arrested curved surface and is approached, and realization clamps disconnected band, arrests roller 4 in clamping and upper arc arrests the frictional force effect of curved surface
Under, disconnected band slows down, while clamping is arrested roller 4 and rotated, and arrests the stopper tab on roller 4 when clamping and touches upper fixed system
When the side end face of dynamic beam 5, the disconnected band after deceleration is locked.While the rotation of upper rotation brake beam, upper rotation brake beam 2 liberates song
Handle ontology 8, crank body 8 rotate, and backspin brake beam 9 is rotated under the effect of gravity, carry out clamping to backhaul adhesive tape and arrest,
Realize broken-belt catching.
When needing to reset weight linear meter 6, capstan winch 11 is modulated into flip bit, capstan winch 11 is rotated backward and pulls out steel wire
Rope is connect by linking up with the link on weight linear meter 6, and capstan winch 11 is modulated and is rotated forward, and rotation capstan winch 11 is pulled upwardly weight linear meter 6,
Rotation brake beam 2 gradually resets on driving simultaneously, under the upper reset of rotation brake beam 2 presses crank body 8 to drive by folding shape connecting rod 7 at present
Rotation brake fine strain of millet resets.It resets and completes, conveyer belt unclamps capstan winch 11 after restoring tension, removes hook and all withdraws wirerope
Capstan winch 11.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
