Description
Technical field
The utility model relates to a kind of novel three-roller calendar, belongs to plastics-production apparatus field.
Background technology
Three-roller calendar often needs to compress into fleece when plastic plate spreading in plastics burnishing process, 2011, applicant has applied for that name is called a kind of utility model patent of three-roller calendar, the patent No. is 201120496304.3, this patent includes frame, frame is provided with top roll, central roll and lower roll three roller, frame is provided with electric heater unit, electric heater unit is arranged on the middle position near top roll and central roll, or/and heater is arranged on the middle position near central roll and lower roll.Although the utility model solves roller easily causes roller and sheet material adhesion to plastic plate intensification, but, less for each roller heating surface (area) (HS, make plastic plate heating surface area less, therefore the calendaring effect does not add, and spreading is entered after fleece, cooling not in time, have impact on the fineness of plastics.
Utility model content
The utility model is intended to solve the problem, and provide a kind of novel three-roller calendar, the technical solution adopted in the utility model is as follows:
A kind of novel three-roller calendar, comprise frame, frame is provided with top roll, central roll and lower roll, three rollers be parallel to each other and top roll and lower roll on a vertical plane, middle roll axis is greater than the distance of upper roll axis to frame to the distance of frame, and middle roll axis is less than the radius of central roll to the distance of frame and upper roll axis to the difference of the distance of frame, and frame is provided with electric heater unit, electric heater unit is arranged on the middle position near top roll and central roll, and frame is provided with the control device of heater.
On the basis of technique scheme, described electric heater unit is circular arc, and described electric heater unit is electric baking lamp, and this structure increases the heating surface area of roller.
On the basis of technique scheme, described control device and electric heater unit electrical connection.
On the basis of technique scheme, in described electric baking lamp, electrical heating wire is set.
On the basis of technique scheme, described middle roll axis is the half of central roll radius to the distance of frame and upper roll axis to the difference of the distance of frame.
On the basis of technique scheme, described top roll, central roll are identical with the radius of lower roll roller.
The utility model tool has the following advantages: top roll, central roll and lower roll be not on same vertical plane, increase the contact area of sheet material and roller, electric heater unit is set to arc, increase the heating surface area of top roll and central roll, fleece is conducive to compress into plastic plate, and increase the cornerite of plastic plate on central roll, utilize plastic plate to cool, improve the fineness of plastic plate.
