Technical field
The utility model relates to a kind of floating roller, more precisely the floating roller of a kind of PUR.
Background technology
The utility model relates to the application of PUR on the hot coated product of molten condition.For adapting to environmental requirement, in the application of food, medicament packaging container label, people use papery bottle label or neck label gradually, why these paper labels can be attached on vial, carry out hot-rolling coated heat melten gel at the back side of paper exactly, after coating, in order to guarantee the smooth and level property of PUR, just need the floating roller of a kind of special PUR.
PUR is thermoplastic resin, be coated on a kind of base material by T-shaped die extrusion with after plastic extruder EVA plasticizing, or with the compound pressing of another base material, cooling, make the method for laminated film.
PUR is again a kind of solvent-free adhesive, is being heated to after 230 ℃ fluidify after PUR fusing.PUR main application is to do the hot sealing layer of packaging material; Also use as precoating composite base material.
The apparatus and process feature of PUR coating is: all cylinders and coating fluid must heat equably in whole plant width, and in the time using the coating of intaglio plate device, coating roller must heat; In the time of the full-bodied PUR of coating, spreader also needs heating.In order to be coated with evenly, regulate coating thickness, general each cylinder drives respectively.The chill roll that needs to install cooling effect below of apparatus for coating, makes PUR cooling in time, obtains bright and clean heat-seal adhesive glue face.
On base material, be coated with after PUR, because base material itself is cool property, PUR stops flowing after running into cold base material at once, the necking down that adds PUR is larger, so cooling front PUR on microcosmic with regard to rough and uneven in surface, glue is apprehensive unreal, in the time sealing with cup, just envelope is not firm in injustice or glue apprehensive place.Need to use the floating roller of heat first floating cooling again, the PUR of heat coating will be more smooth, bright and clean.
Utility model content
The utility model discloses the floating roller of a kind of PUR, the scraggly shortcoming that its hot coated heat melten gel that can solve prior art existence occurs on microcosmic.
The floating roller of a kind of PUR, comprise a roll body, described roll body inside is provided with a pipeline, and a side of described pipeline send oil pipe to connect a fuel reserve tank by one, the opposite side of described pipeline connects described fuel reserve tank by an oil return pipe, one gear pump is sent to the conduction oil of described fuel reserve tank inside in described pipeline, and then is sent to described fuel reserve tank inside by described oil return pipe.
Described fuel reserve tank inside is provided with a heater.
Described gear pump drives by a pump motor.
The left and right sides of described pipeline respectively by one swivel joint connect oil return pipe and described in send oil pipe.
Described roll body is connected and is driven by a synchronous cog belt, and described synchronous cog belt is connected and driven by a variable-frequency motor.
Also comprise a spacer, described variable-frequency motor is fixed on described spacer.
Described fuel reserve tank inside is provided with a thermocouple.
The beneficial effects of the utility model are, under 230 ℃ of roll surface temperatures, can be floating the glued membrane of uneven wire drawing shape, and after chill roll is cooling, glued membrane light, smooth, smooth after being attached on bottle, there is no bubble, a bulge phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Further set forth the specific embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in Figure 1, the floating roller of a kind of PUR, comprise a roll body 2, described roll body inside is provided with a pipeline, and a side of described pipeline send oil pipe 7 to connect a fuel reserve tank 10 by one, the opposite side of described pipeline connects described fuel reserve tank by an oil return pipe 13, and a gear pump 9 is sent to the conduction oil of described fuel reserve tank inside in described pipeline, and then is sent to described fuel reserve tank inside by described oil return pipe.Described fuel reserve tank inside is provided with a heater 11.Described gear pump drives by a pump motor 8.The left and right sides of described pipeline respectively by a swivel joint 1,3 connect oil return pipes and described in send oil pipe.Described roll body is connected and is driven by a synchronous cog belt 4, and described synchronous cog belt is connected and driven by a variable-frequency motor 5.Also comprise a spacer 6, described variable-frequency motor is fixed on described spacer.Described fuel reserve tank inside is provided with a thermocouple 12.
The utility model is selected the stainless steel rod of an external diameter 78.1mm, and the wheeled litter of getting on the bus becomes slender axles, and axle external diameter car becomes 78mm, and axle outer surface is carried out to polishing.To floating roller cleaning, oil removing after polishing.
The utility model provides a kind of can be heated to 230 ℃ floating stainless steel roller roll surface temperature.This floating roller can High Rotation Speed, simultaneously again with constant surface temperature.The utility model has utilized PUR also not having completely when cooling exactly, protruding local glue is melted again with the floating roller of 230 ℃ of rotation, allow melt, mobile glue flows to recessed place, uses the external force of floating roller to reach the smooth object of glue
Bearing is installed at floating roller two ends, and bearing is set in aluminium alloy post, support support shelves are installed simultaneously, and the outer belt gear that installs of support shelves, the variable-frequency motor of floating roller is installed and is fixed, and motor connection line is connected correctly with frequency converter.
Install left and right at floating roller two ends and use single-pass swivel joint, high temperature resistant soft the connecting of swivel joint, firm junction sealing, must not have the place of seepage with polytetrafluoro adhesive tape.Right side pipeline is connected with gear delivery side of pump, carries out leakproof operation with sealant tape.
