Description
Technical field
The utility model relates to a kind of positioner for polymer-extruded foam sheet surfacing, mainly is a kind of surfacing for polymer-extruded foam sheet, belongs to plant equipment and manufacturing field.
Background technology
The subsequent treatment that is generally used for polymer sheet all adopts tri-roll press machine, and still, tri-roll press machine in the course of the work, sheet material is during through three rollers, distance and the asynchronism(-nization) of two sides institute warp, so, different stretchings can be caused in the two sides, thereby produces the difference of stretching internal stress.High molecular polymer is a kind of backbone, in process, particularly extrudes in the processing, and strand can cause orientation.For extrusion sheet, if the tensile stress on two sides is not simultaneously, the orientation on two sides will be inconsistent.This product, even the quality on the product two sides of harsh output is even, and after tensile stress discharged, the product quality of both sides can cause inhomogeneous.Simultaneously, because two sides pressurized situation is different so that the shaping effect on two sides is also different.For the extrusion foaming sheet material, foaming process is so that the polymer volume when going out die orifice sharply expands, and still, the time of this process is very short, causes expanding rapidly and causes wash boarding.This defective of common tri-roll press machine causes more easily that shaping effect is not good and the shaping effect difference two sides is very large.
The utility model content
Technical problem to be solved in the utility model provides a kind of positioner of polymer-extruded foam sheet surfacing, its lower roll that registration roller is installed rear and tri-roll press machine forms a detent mechanism, need the extrusion foaming sheet material of shaping first by registration roller and lower roll, make between lower roll and the registration roller and begin sheet material is repaired, simultaneously, design governor motion, so that registration roller can change extrusion sheet as required by shaping distance and the time of lower roll, thereby realize through producing the extrusion foaming sheet material of surfacing and two sides quality uniformity behind the tri-roll press machine.And in long-term placement, behind the internal stresses release of extrusion foaming sheet material, still can keep the smooth uniformity with the two sides quality in two sides.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of positioner for polymer-extruded foam sheet surfacing, include the gripper shoe of both sides, be rotatablely equipped with lower roll between the supported on both sides plate, be fixedly connected with steady brace between the gripper shoe of described both sides, laterally be slidingly fitted with regulating block on the gripper shoe, be installed with cover plate on the gripper shoe lateral wall, be screwed with adjusting screw(rod) on the cover plate, the front end overhead of adjusting screw(rod) is in the regulating block outer wall, have the arc groove on the regulating block, be provided with the location roll shaft in the arc groove, the location roll shaft front end turning set of both sides is equipped with registration roller, has the gap between registration roller and the lower roll.
Described registration roller and described steady brace are fixed on the gripper shoe by plain washer, spring washer and nut.
Described cover plate is fixed by screws on the gripper shoe, and described adjusting screw(rod) is fixed on the regulating block by plain washer, spring washer and nut.
Circlip for hole and bearing are installed on the described registration roller, and described registration roller is fixed on the regulating block by plain washer, spring washer and nut.
In the utility model for the surfacing of extrusion foaming sheet material and the uniformity consistency of two sides quality, adopt the registration roller that freely rotates to increase surperficial shaping distance and the time of extrusion foaming sheet material, and so that the shaping distance of two sides process keeps basically identical with the time, thereby the surperficial shaping effect that guarantees the extrusion foaming sheet material is better, simultaneously, so that the two sides molecular chain orientation degree of extrusion foaming sheet material is identical, and the internal stress on the cross section of sheet material keeps uniformity, therefore, better by the extrusion foaming sheet material shaping effect that positioner is repaired out, and the two sides uniformity.A kind of for polymer-extruded foam sheet surfacing device, its feature shows that also registration roller has radially and the design of adjusting along tri-roll press machine lower roll cambered surface direction, and radially adjusted design can change the distance of positioner and tri-roll press machine lower roll to adapt to the thickness of different extrusion foaming sheet materials; Along the design of tri-roll press machine cambered surface direction adjustment can change be trimmed the extrusion foaming sheet material shaping distance and time of process, to adapt to the requirement of different sheet materials.
The implementation of guiding mechanism, realize that the scheme of radially adjusting is, unclamp the nut on the adjusting screw(rod), then with screw rod to the left or to the right (as shown in Figure 1) just can drive regulating block and move to the left or to the right, move to the left or to the right thereby drive registration roller, thereby the distance between registration roller and tri-roll press machine lower roll reduced or increase.Realization along the scheme of tri-roll press machine lower roll cambered surface direction adjustment is, unclamps the nut of location roll shaft, the arc groove of registration roller along regulating block moved up or down, thereby adjustment sheet shaping distance and time of process.This design has increased the applicability of positioner greatly.The positioner that is used for polymer-extruded foam sheet surfacing, thereby improve the extrusion foaming sheet material surperficial shaping effect and also so that two sides shaping effect uniformity, simultaneously, place for a long time at the extrusion foaming sheet material, still can keep good surface effect and the uniformity of two sides effect behind the internal stresses release.
The utility model has the advantages that:
The utility model has the advantage of at common tri-roll press machine and designed a kind of positioner for polymer-extruded foam sheet surfacing, make the extrusion foaming sheet material two sides that is trimmed the distance of process be consistent with the time, thereby improve effect and so that the two sides shaping effect uniformity of the surperficial shaping of extrusion foaming sheet material.Simultaneously, positioner has radially and the function of adjusting along tri-roll press machine lower roll cambered surface direction, thereby has greatly increased the applicability of positioner.
