Wherein, the movable track of the cylinder connecting groove 523 and the movable track of the axial line of the clamping piece 3 have an intersection point; when the bobbin feeding part 52 needs to be controlled to receive a bobbin, the upper end of the sector plate 522 is controlled to rotate towards the direction far away from the clamping arm assembly 2 only by the second driving device 53 until each bobbin receiving groove 523 is communicated with the lower end of the discharge hopper 51, at this time, the bobbin stored in advance in the discharge hopper 51 rolls down under the action of gravity and finally falls into each bobbin receiving groove 523, and thus the bobbin receiving work of the bobbin feeding part 52 is completed; when the bobbin feeding part 52 needs to be controlled to transfer the bobbin to the clamping arm assembly 2, the upper end of the sector plate 522 is controlled to rotate towards the direction close to the clamping arm assembly 2 only by the second driving device 53 until the axis of the bobbin receiving groove 523 coincides with the axis of the clamping part 3, wherein in the rotating process towards the direction close to the clamping arm assembly 2 at the upper end of the sector plate 522, the outlet at the lower end of the discharging hopper 51 can be blocked by the cambered surface of the sector plate 522, so that the effect of preventing the bobbin in the discharging hopper 51 from directly falling off from the discharging hopper 51 is achieved.

As shown in fig. 3 and 5, the rotating shaft mechanism 6 includes a first rotating shaft 61 rotatably connected to the frame 1 and a first driving device 62 for driving the first rotating shaft 61 to perform reciprocating rotation; wherein, two fixed parts 21 are both fixed on the first rotating shaft 61 and are respectively arranged near two sides of the frame 1.

When the rotating shaft mechanism 6 is required to control the clamping piece 3 to be close to the cylinder access slot 523 or the friction roller assembly 4, the first rotating shaft 61 is only required to be controlled to rotate by the first driving device 62.

The first driving device 62 and the second driving device 53 may adopt a belt pulley transmission mechanism, a chain sprocket transmission mechanism or a link transmission mechanism, an implementation schematic diagram of the link transmission mechanism is specifically disclosed in the drawings of the present specification, specifically, the link transmission mechanism includes at least one cylinder, a piston rod of the cylinder is indirectly rotatably connected with a rotating shaft (the first rotating shaft 61 or the second rotating shaft 521), and a cylinder body end of the cylinder is rotatably connected with the frame 1, at this time, end points at two ends of the cylinder and an axis of the rotating shaft are arranged in a triangle, and when the cylinder is ejected, an end of the cylinder close to the rotating shaft rotates around the axis of the rotating shaft, thereby achieving an effect of driving the rotating shaft to rotate.

As shown in fig. 6 and 7, the outer support assembly 7 includes a guide block 71 disposed on the frame 1 and located between the two movable arms 22, and two opposite surfaces of the two movable arms 22 are respectively attached to two sides of the guide block 71; wherein, the front view of guide block 71 is the setting of isosceles trapezoid, and the upside length of guide block 71 is less than downside length, and the side view of guide block 71 is the setting of arc form, and the cambered surface of guide block 71 and first pivot 61 coaxial line set up.

Because the width between the two isosceles sides of the guide block 71 is gradually increased from top to bottom, when the end of the two movable arms 22 away from the frame 1 rotates downward, the two movable arms 22 are limited by the two isosceles sides of the guide block 71, so that the two movable arms 22 move in opposite directions, and the distance between the two movable arms 22 is increased to complete the action of releasing the roving roll.

As shown in fig. 8, the pushing-in assembly 8 includes two extending portions 81 respectively disposed on opposite sides of the two fixing portions 21, two guide rods 82 respectively disposed on opposite sides of the two movable arms 22 and respectively passing through the two extending portions 81, and two second springs 83 respectively sleeved on the two guide rods 82; the two extending portions 81 are located on a side surface of the fixing portion 21 away from the first rotating shaft 61, the second springs 83 are located on a side surface of the two movable arms 22 opposite to each other, and two ends of the second springs are respectively attached to the extending portions 81 and the movable arms 22.

When the two movable arms 22 move in opposite directions, the two second springs 83 are both stressed and compressed, and when the rotating shaft assembly drives one end of the two movable arms 22 away from the rack 1 to rotate upwards, the distance between the two movable arms 22 is limited by the guide block 71 to be smaller, so that the two movable arms 22 can move in opposite directions under the pushing of the second springs 83.
