At this time, the driving assembly drives the locking piece 6 to move relative to the rotation piece 3 to expose the escape through hole 304. And then the oil cylinder 5 drives the bearing seat 2 to retreat, the ejector rod 4 synchronously moves along with the bearing seat 2 and penetrates through the avoiding through hole 304, and the first bearing seat 28 on the bearing seat 2 is separated from the shaft head of the scale breaking roller 22 to finish unlocking.

Make the cover have the dust cover all the time on the outer wall of guiding axle 10 and protect, avoid having impurity to fall on guiding axle 10, cause the wearing and tearing of guiding axle 10 and axle sleeve 11 when axle sleeve 11 moves on guiding axle 10.

In the present embodiment, referring to fig. 2 and fig. 7, the detecting assembly further includes a second detecting element 9, and the second detecting element 9 is disposed on the bottom plate 16. When the bearing seat 2 moves to the partition 17 to coincide with the bottom plate 16, the bearing seat 2 moves away relative to the front baffle plate 24 and slides to a stroke detection triggering position, and the first bearing seat 28 on the bearing seat 2 is separated from the shaft head of the scale breaking roller 22, so that unlocking is completed. The partition 17 moves to the side of the second detection part 9, the second detection part 9 detects the partition 17 and sends out a detection signal, and the controller controls the oil cylinder 5 to stop working according to the detection signal. Thereby avoiding the continuous work of the oil cylinder 5 to drive the bearing seat 2 to retreat all the time and collide and interfere with other parts.

Meanwhile, as shown in fig. 5, a limiting member is further provided in the present embodiment, the limiting member is a limiting rod 20, the limiting rod 20 is disposed on the rear baffle 25, and the limiting rod 20 extends toward the front baffle 24 along the length direction of the guide shaft 10. When the bearing seat 2 moves away from the front baffle 24 and slides to the stroke detection triggering position, the tail end of the bearing seat 2 abuts against the rod head of the limiting rod 20. If the second detection piece 9 is damaged, the bearing seat 2 is limited through the limiting rod 20, so that the bearing seat 2 is prevented from always returning to collide with other parts to interfere with the other parts, and the safety of the equipment is further improved. And at the moment, a gap is still left between the first bearing seat 28 and the bottom plate 16 in the horizontal direction, so that the collision interference between the bearing seat and the bottom plate 16 in the process of retraction is avoided.

In this embodiment, the rear baffle 25 is provided with a through hole, and a nut is disposed at the through hole. The outer wall of the limiting rod 20 is provided with external threads, and the limiting rod 20 is in threaded fit with the nut. The limiting rod 20 is matched with the nut in a threaded mode so that the limiting rod 20 can be conveniently disassembled and assembled. When the stop rod 20 is damaged, the stop rod 20 can be replaced quickly. And because the stop lever 20 is in threaded fit with the nut, the positioning distance between the bearing seat 2 and the rear baffle 25 can be adjusted only by turning the stop lever 20.

It should be noted that, in the present embodiment, the limiting rod 20 is disposed on the rear flap 25, but the limiting rod 20 is disposed on the side plate 15, and the limiting rod 20 extends along the width direction of the base 1, so that when the carrying seat 2 slides to the stroke detection triggering position relative to the front flap 24 by moving away, the carrying seat 2 may abut against the rod wall of the limiting rod 20.

Example 2: as shown in fig. 9, the main difference between the present embodiment and the shaft seat drive lock control mechanism in embodiment 1 is that the pivot 601 is located obliquely above the escape through hole 304 on the rotating member 3, and when the push rod of the cylinder 26 extends to press the first portion 602 of the locking member 6 to rotate downward around the pivot 601, the first portion 602 of the locking member 6 blocks the escape through hole 304. When the first portion 602 of the locking member 6 is rotated upward about the fulcrum 601 by the contraction of the push rod of the cylinder 26, the first portion 602 of the locking member 6 is rotated about the fulcrum 601 to expose the escape through hole 304. In the embodiment, the weight of the locking member 6 in the first portion 602 is greater than that of the second portion 603, and if the cylinder 26 fails, the first portion 602 falls down around the fulcrum 601 by its own weight to shield the escape through hole 304 after losing the force of the cylinder 26.

It should be noted that, although in the above two embodiments, the cylinder 26 is connected to the first portion 602 of the locking member 6, the cylinder 26 may be connected to the second portion 603 of the locking member 6 by driving the second portion 603 of the locking member 6 to rotate up and down around the fulcrum 601 to shield or expose the escape through hole 304.
