The working method of the automatic film pressing device of the sampling head comprises the following steps:
as shown in fig. 7 and 8, a sampling head 1 to be pressed is placed on a sampling head tray 2, a driving motor 8 is started, the driving motor 8 drives a driving deflector rod 6 to rotate clockwise, a driving groove 61 on the driving deflector rod 6 rotates clockwise along with the driving deflector rod, a driving deflector block 62 clamped in the driving groove 61 is driven to rotate, the driving deflector block 62 rotates to drive a boss 9 to slide along a sliding groove 13, and further a rolling wheel 4 is driven to rotate on a mounting disc 11 by taking a connecting rod rotating shaft 5 as a rotating center, the center distance between the rolling wheel 4 and the sampling head tray 2 is gradually reduced, the rolling wheel 4 starts to contact with a sealing ring of the sampling head 1, the sealing ring is folded and folded, the sealing ring acts on the rolling wheel 4 due to deformation force generated by folding and pressing, and the feeding movement of the rolling wheel 4 is hindered;
when the center distance between the rolling wheel 4 and the sampling head tray 2 is reduced to the extent that the edge sealing ring on the sampling head 1 is folded and pressed with the rolling wheel 4, the rolling wheel 4 is subjected to the deformation force generated by the edge sealing ring and the edge flanging, and cannot move towards the center direction of the sampling head tray 2, the pressing wheel connecting rod 3 cannot rotate around the connecting rod rotating shaft 5 any more, and at the moment, under the driving of the driving deflector rod 6, the mounting plate 11 rotates clockwise along with the pressing wheel connecting rod 3 around the central axis of the sampling head tray 2, so that the rolling wheel 4 is driven to rotate along the circumference of the sampling head 1, and the rolling flanging of the whole circumference edge sealing ring of the sampling head 1 is realized.
Under the rolling action of the rolling wheel 4, the flanging deformation degree of the edge sealing ring of the sampling head 1 is continuously increased, the flanging deformation force of the rolling wheel 4 is gradually reduced, the pinch roller connecting rod 3 is driven by the driving deflector rod 6 to rotate clockwise around the connecting rod rotating shaft 5, the rolling wheel 4 further moves towards the center direction (rolling feeding direction) of the sampling head tray 2, and the whole film pressing flanging process of the edge sealing ring of the sampling head 1 is gradually completed.
