Abstract

The utility model discloses an automatic adjusting device for adjusting the gap between a pressing belt and a heat plate in the corrugated paper production line, which comprises a hydraulic valve that controls the work of a press roller elevation mechanism, and also comprises a displacement sensor, a data collecting module, a PLC programmable controller and a contactor, wherein, the displacement sensor is installed at the position that can reflect the elevation variation of the press roller and is used for instantly collecting the information of the gap between the pressing belt and the heat plate and for converting the information into an electric signal to be transmitted to the data collecting module, and the data collecting module transmits the collected signal to the PLC programmable controller, and the PLC programmable controller compares the pre-determined gap data with the collected gap data, and the comparison result is used as an order to be transmitted to the contactor, and the contactor controls the work status of the hydraulic valve. The automatic adjusting device can automatically adjust the gap between the pressing belt and the heat plate, and can ensure that the gap stays at the applicable range, thereby reducing the discarded products.

Description

The self-checking device that is used for gap between corrugated paper production line pressure zone and the hot plate

Technical field

The utility model relates to a kind of corrugation production equipment, relates in particular to a kind of self-checking device that is used for gap between corrugated paper production line pressure zone and the hot plate.

Background technology

Corrugated multilayer has some individual layer corrugated papers applyings to form, some individual layer corrugated papers and another layer corrugated paper or facial tissue enter between pressure zone and the hot plate fits, gap between pressure zone and the hot plate is directly connected to the quality of applying quality, if the gap between pressure zone and the hot plate is big, bonding bad coming unstuck between each layer, form empty the subsides, directly produce waste product; If the gap between pressure zone and the hot plate is little, can cause stupefied intensity and the anti-seismic performance that does not reach corrugated paper equally of collapsing.Therefore the control of the appropriateness in described gap is the key that can product qualified, the technical measures in this gap of control are to determine by manual measurement corrugated board finished product whether described gap is suitable at present, this measure has its weak point: when finding defective work, produced a large amount of defective works.In process of production because the gap of pressure roller and hot plate has determined the gap of pressure zone and hot plate, and the lifting of pressure roller is to depend on the promotion of hydraulic cylinder and keep fully, because hydraulic oil itself has compressibility, the cumulative errors of driving member change in the middle of some in addition, cause each uncertainty, inexactness of adjusting and not directly perceived, therefore present corrugated paper production equipment is because this adjustment inconvenience is higher to the percent defective that makes cardboard.

The utility model content

The purpose of this utility model is to provide a kind of can regulate gap between hot plate and the pressure roller in real time, reduces the self-checking device that is used for gap between corrugated paper production line pressure zone and the hot plate of percent defective.

The utility model is used for the self-checking device in gap between corrugated paper production line pressure zone and the hot plate, the hydraulic valve that comprises the work of control pressure roller elevating mechanism, also comprise displacement transducer, data acquisition module, the PLC Programmable Logic Controller, contactor, wherein displacement transducer is installed in the position that can reflect that the pressure roller lifting changes, gather in real time the information in gap between pressure zone and the hot plate and become the signal of telecommunication to reach data acquisition module this information translation, this data acquisition module is delivered to the PLC Programmable Logic Controller with the signal of gathering, this PLC compares the gap data of predefined gap data and collection, comparative result is issued contactor as instruction, by the duty of contactor control hydraulic valve.

Operation principle of the present utility model is: because pressure zone tightly is attached to work under each pressure roller with tensioning state, adjust the spacing of pressure roller and hot plate, the actual spacing that just equals to have adjusted between pressure roller and the hot plate, and because hot plate is fixed, therefore the adjustment up and down of pressure roller has determined the gap between pressure roller and the hot plate, has determined the gap between pressure zone and the hot plate thus.Because the utility model is provided with the automatic control that constitutes with displacement transducer, PLC etc., displacement transducer is installed in the position that can reflect the pressure roller lifting, it is transferred to PLC by data acquisition module in real time with the spacing between pressure roller and the hot plate, analyze computing by PLC by the software of establishment, the gap data of collection and the gap data of setting are compared, comparative result is passed to contactor, by contactor control hydraulic valve.When the actual gap value departs from the interstice coverage of setting, PLC sends instruction to contactor, start hydraulic valve forward or backwards, pressure roller is risen or decline, automatically regulate the gap, therefore the utility model can guarantee gap between pressure zone and the hot plate in applicable scope, thereby reaches the purpose that reduces waste product.

The specific embodiment

From Fig. 1 and Fig. 2 as can be seen corrugated paper production equipment have pressure zone 1, pressure zone strainer 2, hot plate 3, pressure roller 4, pressure roller elevating mechanism 5, the lifting of this elevating mechanism is controlled by hydraulic valve, and what the utility model adopted the control of described hydraulic valve is control automatically in real time.

The formation of the utility model self-checking device as can be seen from Figure 3, the utility model comprises the hydraulic valve of decision pressure roller elevating mechanism, displacement transducer, data acquisition module, the PLC Programmable Logic Controller, contactor, wherein displacement transducer is installed in the position that can reflect that the pressure roller lifting changes, as the pressure roller installing rack, the elevating lever of pressure roller elevating mechanism is first-class, the gap data that displacement transducer will be gathered in real time (gap between pressure zone and the hot plate) converts the signal of telecommunication to and is sent to data acquisition module, data acquisition module is delivered to PLC after reading the data of collection, the gap data that setting is arranged in the PLC Programmable Logic Controller, PLC analyzes computing by the software of establishment, the gap data of collection and the gap data of setting are compared, comparative result is passed to contactor with electrical signal form, contactor is according to the instruction control hydraulic valve of PLC, perhaps forward is connected or is oppositely connected, make pressure roller or liter or fall, the gap of pressure zone and hot plate is either large or small to be regulated in real time.The gap data of setting determines as required that by the user the utility model can be equipped with touch-screen, and the gap data of setting is imported thus, perhaps rewrite the gap data of former setting thus, very convenient, can see on-the-spot gap adjustment situation simultaneously, very directly perceived.Control flow as shown in Figure 2, when the gap width of gathering is in the setting range applicatory, it is stable that system keeps, when the gap width of gathering departs from the scope of application of setting, PLC sends instruction to contactor, start the hydraulic valve forward and connect or oppositely connect, move or move down the purpose that reaches the adjusting gap on the pressure roller thereby make.Gap between pressure zone and the hot plate can automatically accurately be regulated, guaranteed the production of corrugated paper energy continous-stable and good quality is arranged.
