Compounding machine nip rolls and processing method thereof

Technical field

The invention belongs to the printing mechanism technical field, relate to a kind of compounding machine nip rolls, also relate to the processing method of this kind compounding machine with nip rolls.

Background technology

In food or medicine packing, often to use the composite of aluminium foil and PE or PET etc.At the compound tense that carries out of materials such as aluminium foil and PE or PET, wrinkle phenomenon appears in existing aluminum guide roller roll surface in the compounding machine when contacting with the aluminium foil material, influences the quality of product.At this phenomenon,, we walk to expect route, reduce the cornerite of aluminium foil on guide roller, improve various ways such as guide roller surface smoothness and attempt that effect is also not obvious although adopting to shorten; Though can solve the problem that aluminium foil is crumpled with the steel guide roller,, can not satisfy the combination process of plastic sheeting and plastic sheeting again because of its rotary inertia is bigger.

Summary of the invention

The objective of the invention is, a kind of compounding machine nip rolls is provided, substitute the guide roller in the existing compounding machine, can satisfy the technological requirement of carrying out compound tense of materials such as aluminium foil and PE or PET, can satisfy the combination process requirement of plastic sheeting and plastic sheeting compound tense again.

Another object of the present invention is, the processing method of this kind compounding machine with nip rolls is provided, and this processing method is simple, easily operation.

The technical solution adopted in the present invention is, a kind of compounding machine nip rolls, evenly be provided with some concave planes at the nip rolls circumferential surface, each concave plane is a symmetry with the axis mid point of nip rolls, being splayed configuration tilts to the nip rolls two ends, the transition of circular arc concave surface is adopted in the place that the Eight characters intersects in the middle of the concave plane, both sides.

Compounding machine nip rolls of the present invention, its feature also is:

The flattening angle of concave plane is 10 °～18 °.

The concave surface width of concave plane is 8～12mm.

Another technical scheme of the present invention is, 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 angle of circular arc correspondence 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 °, each concave plane on one side all 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 of another side correspondence are milled 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 nip rolls of the present invention has solved the wrinkle 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 implemented easily with the processing method uniqueness of nip rolls.

The specific embodiment

The present invention is described in detail below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, compounding machine of the present invention with the structure of aluminium foil nip rolls embodiment is, no longer 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, 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, adding a cutter point schematic diagram of end face in man-hour for nip rolls of the present invention.Requirement according to technology, determine 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 the angle B of EF chord length correspondence and the angle C of circular arc FD correspondence at interval 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 adds man-hour in making, implements according to following steps:

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 angle C of circular arc FD correspondence 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;

Step 2, more as shown in Figure 1, control the value of feeding of lathe and milling cutter well, make the rotation of nip rolls 1 and the feed velocity of milling cutter coordinate, each concave plane 2 is milled with the method for milling according to the angle that flattens angle A, each concave plane 2 on one side all from the termination of nip rolls 1, is milled near the axis mid point near nip rolls 1 always; The rest may be inferred, and all concave planes 2 of another side correspondence are milled out;

Step 3, as shown in Figure 1, the place that the Eight characters intersect in the middle of corresponding concave plane 2, both sides mills out the transition arc concave surface with the nip rolls periphery again, makes two corresponding concave planes 2 be communicated with and gets final product.
