Working principle: when the semi-curing machine is used, the finished semi-curing sheet is conveyed to the cutting platform and the bearing plate 6.1, the electric telescopic rod 8.2 is contracted to drive the cutting knife 1.2 to move downwards through the lifting plate 8.1, and the cutting knife 1.2 drives the inner clamping plate 4.1 and the outer clamping plate 4.2 to move downwards through the elastic connecting part.
When the inner clamping plate 4.1 and the outer clamping plate 4.2 are abutted to the top of the prepreg together, the inner clamping plate 4.1 and the outer clamping plate 4.2 stop moving downwards, the cutting knife 1.2 continuously moves downwards, and the movable plate presses the compression spring, so that the knife edge of the cutting knife 1.2 moves downwards, stretches out from between the inner clamping plate 4.1 and the outer clamping plate 4.2, and cuts the prepreg below.

After the inner clamping plate 4.1 and the outer clamping plate 4.2 are lifted by the movable plate to be separated from the prepreg, at the moment, the tooth blocks of the long tooth surface part of the vertical rack start to be meshed with the first vertical gear and drive the first vertical gear to rotate, the first vertical gear drives the first vertical bevel gear to rotate through the rotating rod, the first vertical bevel gear drives the first transverse bevel gear to rotate through the rotating rod, the first transverse bevel gear drives the first transmission gear to rotate through the rotating rod, the first transmission gear drives the transverse rack 5.3.3 to displace towards the direction far away from the lower clamping plate 5.1, the transverse rack 5.3.3 drives the pull rod 5.3.2 to synchronously displace, the pull rod 5.3.2 is enabled to be separated from the pull plate which is in contact with the pull rod in the initial state, and the transverse rack 5.3.3 drives the height adjusting gear 5.2.4 which is meshed with the short tooth surface of the pull rod, and the height adjusting gear 5.2.4 drives the adjusting screw 5.2.3 to rotate, and the adjusting screw 5.2.2.2.2 is connected with the transverse lifting rod through the threads through the rotating rod, so that the adjusting screw 5.2.3 drives the transverse lifting rod 5.2.3 to displace towards the direction far away from the lower clamping plate 5.1.2.2.2, and the vertical lifting plate is kept away from the vertical lifting plate through the vertical lifting rod 2.2.2.2.

In this process, the transverse lifting rod 5.2.2 moves up to a certain height to start lifting the bottom end of the supporting rod 7.3 to turn upwards, so that the supporting rod 7.3 is turned over integrally, and because in the initial state, the top end of the supporting rod 7.3 is located at the highest position, the top end of the supporting rod 7.3 forms downward turning motion in this process, namely the top end of the supporting rod 7.3 moves downwards, and the pressing plate 7.2 supported by the top end of the supporting rod 7.3 moves downwards along with the descending of the height of the top end of the supporting rod 7.3 under the thrust action of the second spring column 7.5.

When the horizontal rack 5.3.3 is in use, when the horizontal rack 5.3.3 is in displacement and is out of engagement with the height adjusting gear 5.2.4, at the moment, the pull rod 5.3.2 is in abutting connection with the surface of another group of pull plates in the displacement direction, the electric telescopic rod 8.2 is continuously extended and drives the vertical rack to continuously move upwards, the first transmission gear still keeps an engagement state with the long tooth surface of the horizontal rack 5.3.3, the horizontal rack 5.3.3 is continuously displaced and drives the pull rod 5.3.2 to displace, the pull rod 5.3.2 pushes the pull plate in abutting connection with the pull rod to displace, the pull plate drives the transmission frame 5.3.1 to displace along the T-shaped sliding groove, the top end of the transmission frame 5.3.1 is rotationally connected with the bottom end of the lower clamping plate 5.1, the bottom end of the lower clamping plate 5.1 is driven by the top end of the transmission frame 5.3.1 to form horizontal displacement, and the lower clamping plate 5.1 is rotationally arranged on the frame 1.1 through the vertical lifting rod 5.2.1 at the moment, and the lower clamping plate 5.1 is in overturning motion.
In the process, the bottom vertical surface of the lower clamping plate 5.1 is abutted with the stop lever 6.2.1 at the bottom of the bearing plate 6.1, and at the moment, the bottom end of the lower clamping plate 5.1 is outwards turned to form horizontal displacement with a certain distance, so that the stop lever 6.2.1 is pushed to generate displacement in the horizontal direction, and the stop lever 6.2.1 drives the bearing plate 6.1 to displace in the direction away from the output end of the frame 1.1.
In the process, the bearing plate 6.1 drives the pressing plate 7.2 to synchronously displace through the limiting frame 7.4, and the pressing plate 7.2 is at the lowest position at the moment, so that the pressing plate 7.2 and the bearing plate 6.1 clamp and cut the prepreg together to synchronously displace, and one end of the prepreg remained on the lower clamping plate 5.1 is completely pulled away from the lower clamping plate 5.1.
In this process, the receiving plate 6.1 drives the guide block 6.2.2 to slide in the guide rail 6.2.3, and the guide block 6.2.2 drives the limiting block to slide along the chute and compress the negative pressure spring.
When the electric telescopic rod 8.2 is continuously extended, when the long tooth surface part of the vertical rack moves upwards to be separated from the engagement with the first vertical gear, the short tooth surface part of the vertical rack starts to be engaged with the second vertical gear, the vertical rack continuously moves upwards along with the continuous extension of the electric telescopic rod 8.2, the second vertical gear is driven to rotate by the rotating rod to drive the second vertical bevel gear to rotate, the second vertical bevel gear drives the second horizontal bevel gear engaged with the second vertical bevel gear to rotate, the second horizontal bevel gear drives the second transmission gear to rotate by the rotating rod, the second transmission gear drives the lifting gear 6.3.3 engaged with the second horizontal bevel gear to rotate, the lifting gear 6.3.3 drives the lifting screw 6.3.2 to rotate, and the top end of the lifting screw 6.3.2 rotates in the whole spiral pipe formed by splicing four groups of spiral pipe branches.

In the process, the ratchet wheel on the rotating rod between the second vertical gear and the second vertical bevel gear synchronously rotates, and the pawl is kept to be lapped on the surface of the ratchet wheel under the action of gravity, so that the steering of the ratchet wheel is limited.
When the electric telescopic rod 8.2 starts to shrink, the vertical rack is subjected to downward moving acting force, the tooth blocks of the short tooth surface part of the vertical rack move downwards, the inclined surface below the tooth blocks are made to be abutted on the tooth surface of the second vertical wheel, and the ratchet tooth surface on the same rotating rod with the second vertical gear is made to be abutted by a pawl, so that the second vertical gear cannot rotate reversely, the tooth blocks overlapped on the tooth surface of the second vertical gear are extruded inwards to retract into the telescopic cavity, and in this way, the tooth blocks of the short tooth surface part of the vertical rack move downwards one by one, so that the vertical rack can complete the downward moving stroke.
When the tooth block of the vertical rack moves down to the lower part of the second vertical gear completely, the vertical rack moves down when the electric telescopic rod 8.2 continuously contracts, the tooth block of the long tooth part of the vertical rack starts to mesh with the first vertical gear and drives the first vertical gear to reversely rotate, the first vertical gear drives the pull rod 5.3.2 to reversely displace through the first transmission structure 9, the pull rod 5.3.2 reversely displaces to push the pull plate close to the lower clamping plate 5.1 to reversely displace through a spring connected with the pull rod, the pull plate drives the transmission frame 5.3.1 to reversely displace integrally, the transmission frame 5.3.1 pushes the bottom end of the lower clamping plate 5.1 to reversely overturn, and the bottom end of the lower clamping plate 5.1 abutted with the stop lever 6.2.1 is promoted to reversely displace until the transmission frame 5.3.1 is reset, and the lower clamping plate 5.1 is restored to a vertical state.
In this process, the bottom end reverse displacement of the lower clamping plate 5.1 provides a displacement space for inward displacement of the stop lever 6.2.1 and the receiving plate 6.1, the extruded return spring 6.2.5 recovers and pushes the limiting block to reversely displace, the limiting block drives the guide block 6.2.2 to reversely slide in the guide rail 6.2.3, and the guide block 6.2.2 drives the receiving plate 6.1 and the stop lever 6.2.1 to inwardly displace, so that the stop lever 6.2.1 and the receiving plate 6.1 inwardly displace to a state of abutting against the lower clamping plate 5.1 in the vertical state again.
