Because the driving element 4 is the cylinder 41, the supporting strip 23 is fixed in the car body 2, and the piston rod of the cylinder 41 is hinged with the hinged block 311 of the mounting frame 31 through the hinged seat 42, so that in a natural state, the surface of the mounting frame 31 is parallel to the surface of the car body 2, when the plastic coiled material needs to be clamped, the cylinder 41 is started to retract the piston rod, because the distance between the hinged block 311 and the cylinder 41 is shortened, the cylinder 41 can rotate in the cavity 22 between the adjacent support frames 21, the hinged block 311 can also rotate upwards so that the other end of the mounting frame 31 rotates downwards, so that the embedded block 34 and the winding drum are positioned on the same horizontal plane, after the clamping of the embedded block 34 is successful, the cylinder 41 is started again to extend the piston rod, because the distance between the hinged block 311 and the cylinder 41 is lengthened, the cylinder 41 can rotate downwards in the cavity 22, the hinged block 311 can also rotate downwards so as to drive the other end of the mounting frame 31 to turn upwards until the mounting frame 31 collides with the seat 42, thereby enabling the plastic coiled material to be positioned above the supporting frame 21, and realizing the effect that the driving part 4 drives the clamping component 3 to rotate.
Because fixed subassembly 5 includes a plurality of mounting 51 at automobile body 2 surface symmetric distribution, a fixed frame 52 for driving mounting 51 simultaneous movement, be located the mount 53 of fixed frame 52 below and be located mount 53 central point and put and the output shaft is located the electric putter 54 of mount 53 center end, make when a plurality of plastic coiled material place the completion back on the support frame 21 surface, promote fixed frame 52 through electric putter 54 and move, thereby drive a plurality of mounting 51 simultaneous movement who links to each other with fixed frame 52, and then make a plurality of mounting 51 can fix plastic coiled material, make plastic coiled material more difficult emergence in the transportation rock, handling is more stable.
Because the fixing member 51 includes the pressing rod 511 rotating on the top surface of the vehicle body 2 through the first rotating seat 512, the guide rod 513 rotating on the bottom surface of the vehicle body 2 through the second rotating seat 514, the driving rod 515 hinged to the pressing rod 511 and the guide rod 513, the pressing block 516 located at the bottom of one end of the pressing rod 511, and the connecting rod 517 for driving the guide rod 513 to rotate, in the original state, the pressing rod 511 is vertical and the sidewall thereof abuts against the sidewall of the through hole 24, the pressing block 516 is located above the vehicle body 2 and does not cross the boundary of the supporting frame 21, the driving shaft 518 on the connecting rod 517 is located at the topmost end of the driving groove 5131, when the plastic coiled material needs to be fixed, the output end of the electric push rod 54 drives the fixing frame 52 to move downward, so that the driving shaft 518 moves downward and abuts against the inner wall of the driving groove 5131, so that one end of the guide rod 513 rotates downward, thereby driving the other end to lift and driving the driving rod 515 to move both laterally and lift upward in the through hole 24, thereby drive and support depression bar 511 one end and upwards rotate, the other end is towards the antiport of diapire in the reel to make support block 516 can support to press on the diapire in the reel, thereby realized mounting 51 to the fixed effect of reel, and a plurality of mountings 51 are simultaneously to reel both ends synchronous fixation, make the reel more difficult emergence rock, further improved transportation stability.
Because the cross section of the pressing block 516 is arc-shaped and made of rubber materials, the pressing block 516 can be better attached to and pressed against the inner wall of the winding drum due to the arc-shaped cross section, the contact area is increased, the fixing effect is improved, and the rubber materials have higher friction coefficient and better elasticity on the surface, so that the friction force between the pressing block 516 and the inner wall of the winding drum can be greatly improved, the winding drum is more slippery and not easy to separate from the support frame 21, and the transportation is more stable.
Because the bottom of the sliding seat 33 is provided with the sliding block 332 with the inverted-T-shaped cross section, the extending plate 314 is provided with the sliding groove 333, the sliding connection of the sliding seat 33 on the extending plate 314 is realized by the sliding of the sliding block 332 in the sliding groove 333, and the sliding seat 33 cannot be separated from the sliding groove 333 along the vertical direction by the limitation of the sliding groove 333 to the sliding block 332, so that the sliding of the sliding seat 33 is more stable and smooth.
Because the guiding arc surface 341 is opened at the end of the insert 34 away from the slide seat 33, in the process of clamping the insert 34 into the end of the winding drum, the insert 34 is more easily aligned and clamped into the winding drum by the guiding action of the guiding arc surface 341, and the clamping operation is more convenient.
