Abstract
A three-roller press-polishing device with an improved structure relates to the field of PVC plate processing equipment. The three-roller press-polishing device comprises a frame and an upper side roller, a middle side roller and a lower side roller rotatably arranged on the frame, and is characterized in that at least one heating device is arranged in the circumferential direction of the middle side roller. The heating device comprises a plurality of heating rods arranged parallel to the middle side roller and a lamp housing for fixing the heating rods, the lamp housing is mounted on the frame, and the heating rods adopt quartz heating tubes. The utility model has the advantages that the heating device is arranged in the three-roller press-polishing device, so as to solve in the mode of thermal compensate the difficult problems of crystallization and sticking of PVC plates to be processed in the process of press polishing; and at the same time, the improvement cost is low, and the effect is good.
Description
Technical field
The utility model relates to PVC sheet machining apparatus technical field, specifically a kind of three-roll press-polishing device of architecture advances.
Background technology
In PVC plastic plate production line, use a kind of three-roller calendar, its effect is that the plastics of the molten condition of will come out from mould flatten press polish, finally obtains the higher PVC plastic plate of surface smoothness.The three-roll press-polishing device that the core of three-roller calendar is made up of three identical rollers of diameter, during this three-roll press-polishing device work, plastic sheet to be processed, sheet material therefrom advance sheet between the lower roll, from the top roll slice, three rollers itself have the function of heating, finally roll the plate plane that forms high brightness, be widely used in PVC, PP, PE material by twice.
In the mistake of actual production becomes, the phenomenon of crystallization, roll banding can appear in plastic sheet to be processed, sheet material, find that by analyzing us subject matter goes out: in the process of press polish, because heater is arranged, make three rollers self have certain heating function in all rollers.So produced plastic sheet to be processed, a side that sheet material is adjacent with second roller is in heated condition always, and opposite side is in the state of cooling, make that the temperature of plastic sheet to be processed, sheet material both sides is inconsistent, then caused the phenomenon of crystallization, roll banding, as seen these problems are by excessive the causing of sheet material temperature difference to be processed.
Need transform equipment, mainly be to increase heating device, with the form balance PVC plastic plate both sides temperature of thermal compensation.
The utility model content
The purpose of this utility model is to provide a kind of three-roll press-polishing device of architecture advances, and the difficult problem of crystallization and roll banding can appear in plastic sheet to be processed, sheet material and the roller contact-making surface in the solution three-roller calendar burnishing process.
The technical scheme in the invention for solving the technical problem is: a kind of three-roll press-polishing device of architecture advances, comprise frame and be arranged in rotating top roller, middle limit roller and following roller on the frame, it is characterized in that, at least one heater of circumferential arrangement of middle limit roller.
Described heater comprises some heating rods and is used for fixing the lamp housing of heating rod, and described heating rod and middle limit roller be arranged in parallel, and described lamp housing is installed on the frame.
Described heating rod is a quartz heating tube.
The inboard of described lamp housing is a specular layer, can strengthen the thermal effect that adds of heating rod by emission principle.
The beneficial effects of the utility model are: by increase heater in three-roll press-polishing device, form with thermal compensation has solved the PVC sheet material to be processed crystallization in the long-standing burnishing process, the difficult problem of roll banding, improvement cost is low, effective simultaneously, has outstanding effect.
Description of drawings
Fig. 1 is a PVC line system for producing slabs schematic diagram;
Fig. 2 is a structural representation of the present utility model;
Among the figure: 1 frame, 2 top rollers, limit roller in 3,4 following rollers, 5 quartz heating tubes, 6 lamp housings, 7 extruding machines, 8 hauling machines, 9 three-roller calendars.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of three-roll press-polishing device of architecture advances is the core component of three-roller calendar 9, is arranged between extruding machine 7 and the hauling machine 8, forms a PVC panel production line.
A kind of three-roll press-polishing device of architecture advances, comprise frame 1 and be arranged in top roller 2, middle limit roller 3 and the following roller 4 that the axis on the frame is the level of state, top roller, middle limit roller and following roller are arranged on the vertical vertical line, each limit roller all has an independent Electric Machine Control to rotate, and these are prior art.
Main improvement is, at least one heater of circumferential arrangement of middle limit roller.This heater comprises the microscler quartz heating tube 5 and the fixing lamp housing 6 of quartz heating tube; A side of limit roller during a plurality of quartz heating tubes are arranged in form array arrangement, and quartz heating tube is parallel with middle limit roller.
The inboard of described lamp housing is a specular layer, the reflect heat of quartz heating tube can be added thermal effect.Described lamp housing is installed on the frame.
The course of work is: plastic sheet to be processed, sheet material therefrom advance sheet between the lower roll, from the top roll slice, in this process, in the process of operation, can obtain the thermal compensation of quartz heating tube when plastic sheet to be processed, form with thermal compensation has solved the PVC sheet material to be processed crystallization in the burnishing process, the difficult problem of roll banding, improvement cost is low, effective simultaneously.
The utility model is particularly useful for the art designs transformation to existing three-roll press-polishing equipment.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
