A fixing process of a fixing device for PVC wood grain sheet production comprises the following steps:

s1, when the wood grain piece rolling material support is used, the pull rod is pulled upwards firstly, the pull rod drives the two moving rods 510 to move upwards, the moving rods 510 drive the inclined blocks 511 to ascend and press the trapezoidal blocks 507 to slide, at the moment, the trapezoidal blocks 507 drive the pin rods 505 to move towards the inner part of the clamping grooves 503, the two pin rods 505 are released from clamping with the pin holes 508, the second backing plate 502 is pulled upwards to hang the pull rod on the hook at the bottom of the support plate 9, and then the wood grain piece rolling material on the support rod 4 can be taken out for replacement.

S2, after replacement, the second backing plate 502 slides to the top of the base 1 along the sliding groove 501, at the moment, the two pin rods 505 are respectively pressed by the compression springs 506 to move and are clamped inside the pin holes 508 formed in the support rod 4, the support rod 4 is supported, the use and replacement are convenient and simple, and the processing efficiency is improved.

S3, placing one end of the wood grain sheet roll between the transmission press roll 2109 and the guide roll 18, and then starting the motor 2104 to enable the motor 2104 to rotate to drive the transmission press roll 2109 to be matched with the guide roll 18 for transmission, so that the wood grain sheet roll is transmitted to be automatically cut.

S4, starting the hydraulic rod 10 and the cutting head 13, enabling the hydraulic rod 10 to drive the cutting head 13 to move downwards to cut the wood grain pieces, enabling the rectangular plate 11 to move downwards to drive the connecting rod 2107 to deflect through the lever principle, enabling the other end of the connecting rod 2107 to drive the movably connected moving plate 2106 to move, enabling the moving plate 2106 to drive the transmission sleeve 2102 to slide on the surface of the transmission plate 2101, enabling the transmission pressure roller 2109 to move upwards along with the transmission sleeve 2102 to remove the transmission effect between the transmission pressure roller 2109 and the guide roller 18, avoiding the reduction of the service life of the motor 2104 caused by the repeated closing of the motor 2104, and reducing the production cost.

S5, when the cutting aircraft nose 13 cut the wood grain piece, the wood grain piece coiled material can't transmit with guide roll 18 through transmission compression roller 2109, and the column cap 7 is through the cooperation joint of extrusion spring' S support and arc wall 8 this moment, prevents that the wood grain piece coiled material from carrying out the rotation, and main magnet 15 moves down along with connecting plate 12 simultaneously and adsorbs with the cooperation from magnet 20, makes the wood grain piece cutting position by injecing, avoids taking place the skew among the cutting process, promotes the cutting quality.
