Abstract
The utility model discloses a three-roll calender, which comprises a framework. An upper roll, a middle roll and a lower roll are arranged on the framework, and an electric heating device is disposed on the framework, is mounted close to the middle of a space between the upper roll and the middle roll, and/or is mounted close to the middle of a space between the middle roll and the lower roll. The electric heating device is an electric baking lamp fixed onto the framework by a bolt. The three-roll calender has the advantages that when passing through the calender, a laminated plastic plate can be heated, a laminating film and the plastic plate are assuredly combined, the problem that a plate is adhered with rollers when a three-roll barrel is used for heating is avoided, and the plate is prevented from being excessively heated to generate wrinkles due to the fact that the heating device faces to contact surfaces of the two rolls.
Description
Technical field
The utility model belongs to extrusion plastic plate production equipment field, relates in particular to a kind of three-roller calendar that has roasting lamp.
Background technology
Three-roller calendar is usually used in the press polish in plastic sheet, the panel production lines such as extrusion type PVC, PP, PE; Yet the plastic plate that in engineering, often needs reinforcement; So just need in plastic plate, roll into fleece; Yet this technology needs in calendaring technology the temperature of plastic plate higher, and if with the adhesion to plastic plate intensification being prone to cause cylinder and sheet material of the roller of three-roller calendar.
With the immediate technology of this technical scheme be that the patent No. is 99228990.4 Chinese patent; Its technical scheme is: a kind of plastic plate calendering 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, and middle roller is identical with the diameter of lower roller, and the head die lip is installed in the contact-making surface place near upper roller and middle roller.Yet the three-roller calendar that this patent is announced is being used to produce when having the plastic plate that strengthens overlay film because the difficult plate forming difficulty that heats up.
Summary of the invention
The utility model provides a kind of a kind of three-roller calendar that has roasting lamp of producing overlay film sheet material that is applicable in order to solve deficiency of the prior art.
The utility model is realized through following technical measures: a kind of three-roller calendar; Include frame; Frame is provided with top roll, central roll and lower roll three rollers, and three rollers are parallel to each other and on a vertical plane, frame is provided with electric heater unit; Electric heater unit is installed in the midway near top roll and central roll, or/and heater is installed in the midway near central roll and lower roll.
The temperature that control is for ease produced, the further characteristic of this utility model also has, and above-mentioned frame is provided with the control device of heater, and control device and electric heater unit are electrically connected.
As preferably, above-mentioned electric heater unit is an electric baking lamp, is provided with electrical heating wire in the said electric baking lamp.
As preferably, above-mentioned electric baking lamp is through being bolted on the frame.
The beneficial effect of the utility model is: frame is provided with electric heater unit; Electric heater unit is installed near the contact-making surface place of top roll and central roll or is installed in the contact-making surface place near central roll and lower roll; Like this to heating sheet material during through calender through the plastic plate behind the overlay film; With the fusion of assurance overlay film and plastic plate, and avoid adding heat energy and avoid sheet material and roller adhesion with three rollers.And heater can be avoided making sheet material fold occur after the superheated over against two roller contact-making surfaces.

Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structural representation of roasting lamp.
Among the figure, 1, frame, 2, top roll, 3, central roll, 4, lower roll, 5, control device, 6, electric baking lamp, 7, electrical heating wire, 8, bolt.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below through a specific embodiment, and combine its accompanying drawing, this programme is set forth.
[0015] a kind of three-roller calendar shown in Figure 2 like Fig. 1 includes frame 1, and frame 1 is provided with top roll 2, central roll 3 and lower roll 4 three rollers; Three rollers are parallel to each other and on a vertical plane; Frame 1 is provided with electric heater unit, and the electric heater unit in the present embodiment is an electric baking lamp 6, and two roasting lamps have been installed in the present embodiment; First roasting lamp is installed near the contact-making surface place of top roll 2 with central roll 3, and second roasting lamp is installed near the contact-making surface place in the middle of central roll 3 and the lower roll 4.Frame one side is provided with the control device 5 of electric baking lamp, and control device 5 is electrically connected with electric baking lamp.Electric baking lamp is fixed on the frame through bolt 8.
As Fig. 3 wherein electric baking lamp 6 be rectangle, the length of its length is provided with electrical heating wire 7 greater than the length of three rollers in the said electric baking lamp.
This plastic plate strengthens the extruding production line that film covering device is mainly used in plastic plates such as comprising PET, PE, PP.
The utility model can pass through existing techniques in realizing without the technical characterictic of describing, and repeats no more at this.Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also should belong to the protection domain of the utility model.
