Specifically, the steering limiting member comprises a ball 16, the outer side wall of the inner cylinder 13 is provided with a plurality of clamping grooves 17 uniformly distributed along the circumferential direction, the groove depth of the clamping grooves 17 is linearly increased along the forward rotation direction of the outer cylinder 14, the ball 16 is arranged in the clamping grooves 17, when the outer cylinder 14 rotates along the forward rotation direction, the outer cylinder 14 drives the ball 16 to roll towards one end with larger groove depth dimension of the clamping grooves 17, at the moment, the ball 16 is in clearance fit with the inner side wall of the outer cylinder 14, otherwise, when the outer cylinder 14 rotates along the reverse rotation direction, the outer cylinder 14 drives the ball 16 to roll towards one end with smaller groove depth dimension of the clamping grooves 17, at the moment, the ball 16 is in tight fit with the inner side wall of the outer cylinder 14, so that the outer cylinder 14 is fixed with the clamping grooves 17 on the inner cylinder 13 through the ball, and therefore, the outer cylinder 14 can only rotate along the forward rotation direction and the reverse direction with the inner cylinder 13. Further, the two capturing heads 8 of the same capturing mechanism are arranged in opposite rotation directions of the outer cylinder 14, as shown in fig. 7, the forward rotation direction of the outer cylinder 14 of the capturing head 8 at the left end in any capturing mechanism is opposite to the forward rotation direction of the outer cylinder 14 of the capturing head 8 at the right end, so that when the conveyor belt 300 moves leftwards or rightwards, the outer cylinder 14 of at least one capturing head 8 of the two capturing heads 8 rotates along with the linear motion of the conveyor belt 300, and the outer cylinder 14 on the other capturing head 8 slides and rubs with the conveyor belt 300, thereby ensuring that no matter the conveyor belt 300 breaks in front of or behind the frame 1, when the two capturing heads in the capturing mechanism simultaneously abut against the conveyor belt 300, at least one capturing head can slide and rub with the conveyor belt 300, so that the conveyor belt 300 can be fastened quickly.
According to a further preferred example of the present embodiment, as shown in fig. 7, the conveyor belt 300 has an inertial tendency of moving to the left, and at this time, the outer cylinders 14 in the capturing heads 8 located at the right end position in the capturing mechanism are driven by the conveyor belt 300 to rotate in the forward and reverse directions relative to the corresponding inner cylinders 13, and at the same time, the outer cylinders 14 in the capturing heads 8 located at the left end position slide and rub with the conveyor belt 300 under the action of the steering limiting member; similarly, when the conveyor belt 300 has an inertia tendency of moving to the right, the outer cylinders 14 in the capturing heads 8 at the left end position in the capturing mechanism are driven by the conveyor belt 300 to rotate in the forward and reverse directions relative to the corresponding inner cylinders 13, and at the same time, the outer cylinders 14 in the capturing heads 8 at the right end position slide and rub with the conveyor belt 300 under the action of the steering limiting piece. The preferred example of this embodiment aims at that the catching mechanism performs a guiding action in the preceding contact of the catching head in the moving direction of the conveyor belt 300 during the catching of the conveyor belt 300, that is, the outer cylinder 14 on the catching head 8 rolls on the conveyor belt 300, while the other catching head in the following contact enables the conveyor belt 300 to be quickly fastened to a stationary state by sliding friction, and in this process, the conveyor belt 8 is not likely to bend or shake due to excessive instantaneous impact force in the preceding stage of contact with the catching mechanism due to the guiding action of the preceding catching head 8, affecting the catching effect of the following catching head 8.
In some embodiments, the controller is disposed in the middle chamber 10, so that the controller can give a control signal while the conveyor belt 300 breaks or in a shorter reaction time and is used to capture the broken conveyor belt 300, and the embodiment should further include a detection mechanism capable of quickly acquiring the breaking information of the conveyor belt 300, so that the improvement of the embodiment is that: as shown in fig. 7, the carrier plate is provided with two capturing mechanisms uniformly arranged along the circumferential direction of the main channel 2, one of the fixing members 6 in each capturing mechanism is provided with a torsion spring (not shown in the figure) for driving the corresponding swing arm 7 to drive the capturing head 8 to abut against the conveying belt 300, the capturing head 8 where the torsion spring is located is provided with a sensor for detecting the rotation direction and rotation speed of the capturing head 8, and preferably the sensor is an angular velocity sensor. As shown in fig. 7, the four capturing heads 8 include an upper left capturing head 8, an upper right capturing head 8, a lower left capturing head 8 and a lower right capturing head, wherein the lower left capturing head and the lower right capturing head 8 are located on the first capturing mechanism, the upper left capturing head 8 and the upper right capturing head 8 are located on the second capturing mechanism, torsion springs are respectively arranged on the upper right capturing head 8 in the first capturing mechanism and the upper left capturing head 8 in the second capturing mechanism, the torsion springs are sleeved outside a hinge shaft between the fixing piece 6 and the swing arm 7, two ends of the torsion springs are respectively connected with the fixing piece 6 and the swing arm 7, one end of the swing arm 7 with the capturing head 8 is applied to move towards the conveying belt 300 and lightly touches the conveying belt 300 through the elasticity of the torsion springs, so that the lower right capturing head 8 and the upper left capturing head 8 with the torsion springs can rotate along with the conveying belt 300 in the normal conveying direction, namely, the upper left capturing head 8 and the upper left capturing head 8 can be driven by the torsion springs to rotate along the conveying direction, and the upper left capturing head 8 can rotate along the normal rotation range of the upper left capturing head 8 and the upper right capturing head 8 in the normal rotation range of the conveying direction, and the upper right capturing head 8 can be driven by the normal rotation range of the upper right capturing head speed range of the upper right capturing head 8 in the normal rotation range of the rotating speed along the conveying direction. When the conveyer belt 8 breaks, the angular velocity sensors on the right lower capture head 8 and the left upper capture head 8 respond to the velocity change of the conveyer belt 300 to give detection signals, the controller can rapidly control the telescopic push rod in the capture mechanism to work after acquiring the detection signals, the telescopic push rod rapidly stretches, and at the moment, the telescopic push rod drives the right upper capture head 8 and the left lower capture head 8 to be in contact with the conveyer belt 300, and further, the four capture heads 8 are in tight fit with the conveyer belt 300. The advantage of this embodiment is that the four capturing heads in the two capturing mechanisms are not only used as capturing execution components for fastening the conveyor belt, but also two capturing heads can be used as detection components, the outer cylinders on the capturing heads and the conveyor belt 300 are lightly touched and rubbed in a rolling manner during normal feeding of the conveyor belt 300, the influence on the conveyor belt 300 is small, and rapid response can be achieved when belt breakage occurs, so that the four capturing heads 8 simultaneously clamp the conveyor belt 300, and the conveyor belt 300 is stationary relative to the frame 1 under the action of friction force.

As shown in fig. 10, the outer side wall of the outer cylinder 14 is provided with a plurality of grooves 15 formed by inscription, each groove 15 is uniformly distributed along the circumferential direction, the groove 15 comprises a stress surface 15.1 extending along the radial direction and a guiding surface 15.2 extending along the tangential direction, and the stress surface 15.1 and the outer side wall of the outer cylinder 14 and the guiding surface 15.2 and the outer side wall of the outer cylinder 14 are connected through arc surfaces in a transitional manner. The force bearing surface 15.1 faces away from the movement direction of the conveyor belt 300 when the outer cylinder 14 is rotationally matched with the inner cylinder 13 along the forward rotation direction due to the acting force of the conveyor belt 300 on the capturing head 8, and the force bearing surface 15.1 faces towards the movement direction of the conveyor belt 300 when the outer cylinder 14 and the conveyor belt 300 are in sliding friction due to the acting force of the conveyor belt 300 on the capturing head 8.

The embodiment is intersected with the technical scheme that the belt 300 is stationary only by virtue of the sliding friction force between the outer surface of the outer cylinder 14 and the outer surface of the belt 300, so that the time from the belt breakage to the fastening of the caught head 8 to the stationary state of the belt can be obviously shortened, and the catching efficiency and reliability are improved.
In each of the above embodiments, the movement direction of the conveyor belt 300 is S1, and the forward rotation direction of the outer cylinder 14 of the catcher 8 with respect to the inner cylinder 13 is S2.
