Abstract
The utility model discloses a three-roller press for a plastic calender train, which comprises an upper roll, a middle roll and a lower roll, wherein, the diameter of the upper roll is smaller than the equal diameter of the middle roll and the lower roll. A die lip of a head section is arranged near a contact surface of the upper roll and the middle roll. The utility model can obviously shorten the distance between the die lip of the head section and the contact surface of the rolls, increase banding time of plastic sheets and plates, and enable the plastic sheets and the plates with small viscosity and slow crystallization rate to be crystallized and shaped as quickly as possible. The utility model is mainly used for crystallizing and shaping PET plastic sheets and plates, and can also be used for shaping PE, PP, PS, etc. plastic sheets and plates.
Description
The utility model relates to the improvement of plastics calender three-roll press-polishing device.
Three-roller calendar is the extrusion plastic sheet, the critical piece of sheet material subsidiary engine, three-roll press-polishing device is the heart of three-roller calendar, traditional three-roller calendar mainly is suitable for producing PVC, PE, plastic sheets such as PP, sheet material, three roller diameter sizes in the three-roll press-polishing device of this calender are identical, plastic sheet when work, sheet material is from three-roll press-polishing device, advance sheet between the lower roller, from the lower roller slice, or roller therefrom, advance sheet between the lower roller, from the upper roller slice, plastic sheet, the press polish of sheet material, cooling and shaping all is to carry out on the plastics calender of temperature adjustment respectively at three rollers, little to viscosity, the PET plastics that crystallization rate is slow, make its moulding well, then require the distance of die lip outside the roller contact-making surface of calender little, plastic sheet, the banding time of sheet material is long, and the diameter of traditional three rollers of plastics calender is identical, die lip is bigger from the distance at roller contact-making surface place, plastic sheet, the banding time of sheet material is short, is difficult to satisfy plastic sheets such as PET, the requirement of plate forming.
The purpose of this utility model provides a kind of plastics calender three-roll press-polishing device, and it can obviously shorten the distance at head die lip and roller contact-making surface place, and can improve the banding time of plastic sheet, sheet material.
For achieving the above object, the technical solution of the utility model is, a kind of plastics calender three-roll press-polishing device, comprise upper roller, middle roller and lower roller, the diameter of roller and lower roller is little in the diameter ratio of described upper roller, middle roller is identical with the diameter of lower roller, and the head die lip is installed near upper roller and central roll socket joint synapsis.
The utility model has the advantages that: because three rollers of the present utility model are designed to one little two big structure, obviously shortened the distance between head die lip and the roller contact-making surface, increased the banding time of plastic sheet, sheet material, thereby made plastic sheet, sheet material crystallization as soon as possible, the moulding that viscosity is little, crystallization rate is slow.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the right view of Fig. 1.
By Fig. 1 and Fig. 2 as can be known, the utility model comprises upper roller 1, middle roller 2 and lower roller 3, the diameter of roller 2 and lower roller 3 is little in the diameter ratio of upper roller 1, after the diameter of upper roller 1 reduces, upper roller 1 increases with the cylindrical tangential angle of middle roller 2, helps die lip more near the contact-making surface of upper roller 1 with middle roller 2, and middle roller 2 is identical with the diameter of lower roller 3, and diameter is bigger than upper roller 1, and such being provided with can make plastic sheet, sheet material banding time lengthening.Head die lip 4 is installed near the contact-making surface place between upper roller 1 and the middle roller 2, and the plastics extruded stock is from directly delivering to the contact-making surface between upper roller 1 and the middle roller 2 after head die lip 4 comes out.About three rollers are installed in respectively by bearing on two blocks of wallboards 5,6, on three rollers, distance adjustor 7 is set also, distance adjustor 7 is used for regulating three gaps between the roller, be respectively arranged with in the axle head both sides of three rollers can the dancer rools drum surface temperature swivel joint 8, in swivel joint 8, feed the liquid of temperature adjustment, be used for regulating the temperature of roller roll surface, three rollers are connected with power set 10 by sprocket wheel 9.
The utility model is when work, by sprocket wheel 9 power is passed to three rollers by power set 10, three rollers begin to rotate, head die lip 4 is directly delivered to the upper roller 1 of minor diameter and the contact-making surface place between the large diameter middle roller 2 with the plastics extruded stock, the liquid that has regulated temperature in the swivel joint 8 is given three roller temperature adjustments simultaneously, the gap that distance adjustor 7 is regulated between three rollers, the plastics extruded stock is the lengthening of banding time between roller 2 and the lower roller 3 in large diameter, makes plastics extruded stock crystallization and moulding fully well after through three rollers.
The utility model is mainly used in the moulding of PET plastic sheet, sheet material, also is applicable to the moulding of plastic sheets such as PE, PP, PS, sheet material.
