Technical field
The present invention relates to the method for a kind of foam automatic cutting device of tinuous production and foam surface trimming.
Background technology
Domestic production polyurethane thermal insulation board is formed by the rigid poly urethanes block foam cutting of intermittent mode production at present , this method output is small, far can not meet the needs of China building energy conservation market.Therefore, rigid poly urethanes are block Production is bottleneck, and domestic production rigid polyurethane mass is steeped using irony case mould as mould, by A, B component raw material by foaming machine or The artificial stirring of person is passed through mould and foamed.Existing subject matter has:Production capacity is low, and recruitment is more, and labor intensity is big, automatically Change degree is low, and quality control difficulty is big, is unfavorable for the production in scale, while the performance of foam also can not show a candle to continuous foamed block Shape foam.
Invention production polyurethane block rigid foam used in tinuous production, mainly produce using hard polyurethane foam as Core, one side coated with Cement fibre surface layer composite board production line.And the continuous production device of hard-foam polyurethane block foam Belong to the first at home, the foamed machine foaming of polyurethane foam, finger is cut out by production line curing molding, then cleaved device The polyurethane slabstock foam of measured length.Can cutting be used as a polyurethane foam production process segment process therein, continuously automatic Cut and have a great impact to the production efficiency of foam.Meanwhile automatic cutting device is to the cutting accuracy and bubble of foam The foam side of going out rate also has a certain impact.
The content of the invention
It is an object of the invention to provide a kind of rational in infrastructure, the foam continuously produced can be cut by regular length Separation, improves production efficiency and cutting accuracy, increase volume recovery, reduce waste product tinuous production foam automatic cutting device And the method for foam surface trimming.
The present invention technical solution be:
A kind of foam automatic cutting device of tinuous production, it is characterized in that:Including the base that can be moved on guide rail;Bottom Clamping protection unit on seat, carry out guide and limit for the foam that leading portion production line is sent and clamp righting;On base, press from both sides shield dress The side of postponing sets cutter device, and the foam that shaping is had been cured for continuous production line to be produced is cut into pieces;In base Upper setting travel switch, travel switch and the baffle fit on guide rail;Fast conveyor belts are set at base rear, quickly conveyed Band top sets induction installation, for controlling the unlatching of cutter device and the length of adjustment cutting foam.
The folder protection unit is made up of support, deflector roll, pneumatic actuator and clamping dial plate;It is provided with support some flat The deflector roll of row arrangement, is flushed with leading portion foam conveyer belt;At least two pneumatic actuators with clamping dial plate above support, point The both sides of foam direction of transfer are not dispensed along.
The cutter device is made up of gantry stand, vibration head, head driver, slide rail and cutting knife;Slide rail is distributed In gantry stand both sides, vibration head is vibrated by driver along slide rail in moving up and down drives cutting knife to cut foam.
The induction installation is made up of cross bar and sensing apparatus;Cross bar is fixed on conveyer belt along foam travel direction On, the position on cross bar is fixed on by mobile sensing apparatus to adjust the length of cutting foam.
The bottom of base sets roller, is moved under the driving of motor along fixed guide rail.
A kind of method of the foam surface trimming of tinuous production, it is characterized in that:Including:
(1)Sensing step:When foam front end is sent to induction installation, after induction installation captures signal, filled to control Put and send signal;
(2)Folder shield step:Control device sends instruction to folder protection unit, and pneumatic actuator uses under the driving of air pressure Clamp dial plate and foam is clamped into righting;
(3)Cutting step:Foam takes cutter device movement to after clamping, while cutter device starts, and vibration head is driving The cutting of foam cross-wise direction is completed in the presence of dynamic device.
Further comprise:Cutter device return:After continuous foam cutting, base drive device row to guide rail end, which is met, goes Cheng Kaiguan, control device receive switching signal, send instruction to folder protection unit, unclamp fixture.Meanwhile base is in the drive of motor Under dynamic guide rail front end is back to along guide rail.
Further comprise:Foam transmits:After continuous foam cutting, cut foam is comparatively fast conveyed by transfer rate Band is transported at foam stacking.
The advantage of the invention is that:It is spacing to press from both sides side progress of the protection unit to foam, avoids because position deviation influences to cut Cut precision.The automatic control system that foam surface trimming uses is exported to air-operated solenoid valve and closed after induction installation gives signal Suitable current signal, start folder protection unit using air pressure, while open cutter device.After the completion of cutting, cutter device resets, It is ready for next round cutting.The method realizes the automation of cutting overall process, precision, uses the hard bubble upper surface of production It is relatively flat, material rate height is cut, reduces product cost.Manual, semi-automatic, full automatic working can also be realized, equipment is run accurately and reliably.
