Another technical scheme that the present invention adopted is that a kind of above-mentioned compounding machine is implemented according to following steps with the processing method of nip rolls:
The bar number of the concave plane of step 1, first diameter, needs processing according to nip rolls; Calculate the pairing angle of each concave plane chord length, the chord length width value of concave plane, the adjacent concave plane corresponding angle of circular arc at interval; On the circumference of the two ends of nip rolls, carry out a cutter mark of all concave planes; Control concave plane width chord length is set to 8～12mm, selects corresponding milling cutter;
Step 2, the value of feeding of lathe and milling cutter controlled well; Make the rotation of nip rolls and the feed velocity of milling cutter coordinate; Each concave plane is milled with the method for milling according to the angle that flattens the angle; The flattening angle of concave plane is 10 °～18 °, and each concave plane is on one side all begun from the termination of nip rolls, is milled near the axis mid point near nip rolls always; The rest may be inferred, and all concave planes that another side is corresponding mill out;
Step 3, the place that the Eight characters intersects in the middle of corresponding concave plane, both sides mill out the transition arc concave surface with the nip rolls periphery again, make two corresponding concave planes be communicated with and get final product.
Compounding machine of the present invention is used nip rolls, has solved the crumple phenomenon of guide roller roll surface when contacting with the aluminium foil material, satisfies the combination process of aluminium foil, and is simple in structure; This compounding machine is unique with the processing method of nip rolls, implements easily.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is elaborated.
As shown in Figure 1; Compounding machine of the present invention is no longer to adopt existing simple flattening line at nip rolls 1 circumferential surface, but evenly be provided with the concave plane 2 of some smooth transition along circumferential surface with the structure of aluminium foil nip rolls embodiment; Each concave plane 2 is a symmetry with the axis mid point of nip rolls 1; Be splayed configuration and tilt to nip rolls 1 two ends, the transition of circular arc concave surface is adopted in the place that the 2 middle Eight characters intersect in the concave plane, both sides.So both reach the purpose of flattening, and can not scratch material again, satisfied the combination process of plastic sheeting.According to the diameter of nip rolls 1, each concave plane 2 is 10 °～18 ° with the axial horizontal flattening angle A of circumference.
As shown in Figure 2, for nip rolls of the present invention is adding a cutter point sketch map of end face in man-hour.Requirement according to technology; Confirm the bar number of concave plane 2 on the circumference; The plane width EF chord length of concave plane 2 just can be set according to the diameter of nip rolls 1; Circular arc FD length between the adjacent concave plane 2 also goes out corresponding angle B of EF chord length and the corresponding angle C of interval circular arc FD with regard to corresponding calculated.It is 8～12mm that the plane width EF chord length of concave plane 2 is provided with scope, and the degree of depth is 0.1～0.3mm.
Nip rolls of the present invention is implemented according to following steps when fabrication and processing:
Step 1, as shown in Figure 2; The bar number of the concave plane 2 of first diameter, needs processing according to nip rolls 1; Calculate the pairing angle B of each concave plane 2 chord length EF, the chord length EF width value of concave plane 2, the adjacent concave plane 2 corresponding angle C of circular arc FD at interval; On the circumference of the two ends of nip rolls 1, carry out a cutter mark of all concave planes 2, control concave plane width EF chord length is set to 8～12mm, selects corresponding milling cutter;
