Abstract
An air cushion roller pressure controlling device comprises an air cushion roller, and a cavity is formed in the air cushion roller. The surface of the air cushion roller is provided with a plurality of air holes communicated with the cavity, a fan which is arranged outside the air cushion roller is communicated with the inner cavity of the air cushion roller through an air conveying pipe. The inner cavity of the air cushion roller is further provided with an air-pressure sensor, and a central controller is further positioned outside the air cushion roller. The air-pressure sensor is connected with the central controller through a signal wire, and the central controller is connected with the fan. The air cushion roller pressure controlling device enables the air pressure of the inner cavity of the air cushion roller to be controlled within a predetermined range, and resolves the problem that the different plastic film width and different air leaking degrees cause the inner air pressure of the air cushion roller to be too large. The air cushion roller pressure controlling device enables plastic films to float on the surface of the roller, and avoids the operational instability of the plastic films.
Description
Technical field
The utility model belongs to the technical field of plastic foil manufacturing equipment, is specifically related to a kind of air cushion roller pressure control device.
Background technology
The air cushion roller can be used for the plastic foil manufacturing equipment, for example is usually used in the blow moulding machine as guide roller.Compare with other conventional roller, the air cushion roller can make the direct friction on film and roller surface reduce, and avoids directly damaging the plastic foil surface.The inside of air cushion roller is formed with cavity, its surface then is provided with some pores that are communicated with cavity, is provided with blower fan in air cushion roller outside, and blower fan is communicated with by the internal cavities of snorkel with the air cushion roller, therefore can make the pore on air cushion roller surface continue to have pressure, thereby the plastic foil pad is floated over the roller surface.
Traditional air cushion roller, though can control the output pressure of blower fan, but because air cushion roller pore is evenly distributed on the whole surface of air cushion roller, all be distributed with pore from the left end of air cushion roller to right-hand member, the horizontal total length that almost runs through the air cushion roller, the fabric width of corresponding various plastic foils then varies in the use of air cushion roller, therefore after the plastic foil of different fabric widths covers the surface of air cushion roller, the pore quantity of its covering is different, unsheltered pore quantity is different thereupon, and these unsheltered pores are passages that air is overflowed easily, and the internal pressure of air cushion roller must reduce after air was overflowed.So, after the plastic foil of different fabric widths covered the surface of air cushion roller, air cushion roller internal pressure was different, and the deficiency if the air pressure in the air cushion roller is too little is so that film and the isolation of roller surface, otherwise, if the air pressure in the air cushion roller is too big then can influence the stable of film.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of air cushion roller pressure control device is provided, and when it can make the air cushion roller be applied to the plastic foil of different fabric widths, can both reach the air pressure size to fit.
Its purpose can realize by following scheme: this air cushion roller pressure control device comprises the air cushion roller, inside at the air cushion roller is formed with cavity, air cushion roller surface is provided with the pore that several are communicated with cavity, be provided with blower fan in air cushion roller outside, blower fan is communicated with by the internal cavities of snorkel with the air cushion roller, be primarily characterized in that, internal cavities at the air cushion roller also is provided with baroceptor, outside at the air cushion roller also is provided with central controller, baroceptor is connected to central controller by signal wire, and central controller connects blower fan.
Be preferably, described snorkel is installed in air cushion roller center, and both form coaxial and relatively turnable installation relation; Described baroceptor and snorkel are fixed together; The signal wire of described baroceptor passes air cushion roller outside by the snorkel inner chamber.
The utlity model has following advantage and effect:
1, the utility model can be controlled at the air pressure of the internal cavities of air cushion roller in the scope of design, avoid causing the air pressure inside of air cushion roller too big because of plastic sheeting fabric width difference, gas leakage degree difference, both can effectively plastic film pad be floated over the roller surface, and can prevent the plastic sheeting fluctuation of service again.
2, the signal wire of baroceptor passes air cushion roller outside by snorkel dexterously, and in air cushion roller rotation process, this signal wire need not rotate, and snorkel, baroceptor also need not rotate, and make the integral installation simple and ingenious structure.

Fig. 1 is the structural principle synoptic diagram of a kind of specific embodiment of the utility model.
Fig. 2 is an air cushion roller inner structure synoptic diagram.
Fig. 3 is an air cushion roller user mode synoptic diagram.
Embodiment
Fig. 1, air cushion roller pressure control device shown in Figure 2 comprise air cushion roller 1, are formed with cavity 11 in the inside of air cushion roller, and air cushion roller surface is provided with several pores that is communicated with cavity 12, and pore 12 almost runs through the horizontal total length of air cushion roller.Be provided with blower fan 3 in air cushion roller outside, blower fan 3 is communicated with the internal cavities 11 of air cushion roller by snorkel 2, and snorkel 2 tube walls are provided with injection well 21; Internal cavities 11 at the air cushion roller also is provided with baroceptor 4(pressure transducer), also be provided with central controller 5 in the outside of air cushion roller 1, baroceptor 4 is connected to central controller 5 by signal wire 6, and central controller 5 connects blower fan 3.
Shown in Figure 2, described snorkel 2 is installed in air cushion roller 1 center, and extends into air cushion roller cavity 11, and snorkel 2 and air cushion roller 1 are equipped with bearing 7 between the two, makes both form coaxial and relatively turnable installation relation; Described baroceptor 4 is fixed together with snorkel 2; The signal wire 6 of described baroceptor passes air cushion roller outside by snorkel 2 inner chambers, is connected with central controller 5.
Shown in Figure 3, the foregoing description in use, the pore quantity difference that the plastic foil 8 of different fabric widths is hidden can produce different flow leakage amounts.If the flow leakage amount causes air cushion roller 1 air pressure inside too hour too greatly, baroceptor 4 is given central controller 5 with the signal feedback that detection obtains, and central controller 5 order blower fans 3 strengthen output pressures, till air cushion roller inner chamber 11 air pressure meet the requirements.Otherwise the too for a short time air cushion roller air pressure inside that causes of flow leakage amount is too big, and then central controller order blower fan 3 reduces output pressure, till air cushion roller 1 air pressure inside meets the requirements.
