Abstract
The technical scheme of the utility model, an online membrane cooling device of multilayer coextrusion casting membrane machine, it includes the platform frame, deflector roll before being equipped with in proper order between the platform frame of both sides, chill roll, upper and lower chill roll, back deflector roll. The front guide roller is arranged below the corona machine, the cooling roller is close to the front guide roller, the distance between the upper cooling roller and the lower cooling roller is 1.2-1.3 meters, and the rear guide roller is arranged behind the upper cooling roller and the lower cooling roller. The utility model has the advantages that: the utility model discloses can make abundant contact between membrane and the chill roll, make the design effect better, can make the film short time just can use behind the machine, shorten to 6 hours by the 24 hours of placement time, the turnover time is short, reduces simultaneously because of the membrane needs dry in the air for a long time and put the stock problem that causes to the machine speed of production has been promoted, has promoted product quality and production efficiency simultaneously on this basis.
Description
Technical Field
The utility model relates to a multilayer is crowded curtain coating membrane machine altogether, especially a multilayer is crowded curtain coating membrane machine altogether is at online film cooling device.
Background
The plastic film extrusion casting production is easy to be large-scale, high-speed and automatic. The produced film has better transparency than a blown film, improved thickness precision, good uniformity and high strength, and the plasticized raw material is extruded by a casting film machine and then the molten material is cast from the lip of a forming die onto a cooling roller for forming. The difference between the production method of the extrusion casting forming film and the production method of the extrusion blow molding forming film is that: extruding and plasticizing to obtain molten material, uniformly flowing out of the lip of the mould at constant speed, casting on the surface of a cooling roller, cooling and shaping, passing through an on-line thickness measuring and corona treatment device, and rolling to obtain the finished product. If the temperature of circulating water in the cooling roller is too high, the film is easy to soften, stick and deform, if the temperature of circulating water in the cooling roller is too low, the film is hard after being formed, the stretching effect is not ideal, the subsequent product cannot be used in a composite way, meanwhile, the film needs to be placed for shaping for a long time and must be produced at a low machine speed, and the quality and the production cost of the product are seriously influenced.
Disclosure of Invention
The utility model aims at designing a rational in infrastructure, the effectual online film cooling device of multilayer coextrusion casting membrane machine of processing.
The technical scheme of the utility model be, an online film cooling device of multilayer coextrusion casting membrane machine, it includes platform frame, its characterized in that: a front guide roller, a cooling roller, an upper cooling roller, a lower cooling roller and a rear guide roller are sequentially arranged between the platform frames at the two sides.
The front guide roller is arranged below the corona machine, the cooling roller is close to the front guide roller, the distance between the upper cooling roller and the lower cooling roller is 1.2-1.3 meters, and the rear guide roller is arranged behind the upper cooling roller and the lower cooling roller.
The film passes through the front guide roller, then passes through the cooling roller, then passes through the space between the upper cooling roller and the lower cooling roller, and finally passes through the rear guide roller.
The utility model has the advantages that: the utility model discloses can make abundant contact between membrane and the chill roll, make the design effect better, can make the film short time just can use behind the machine, shorten to 6 hours by the 24 hours of placement time, the turnover time is short, reduces simultaneously because of the membrane needs dry in the air for a long time and put the stock problem that causes to the machine speed of production has been promoted, has promoted product quality and production efficiency simultaneously on this basis.
Drawings
Fig. 1 is a schematic view of the exploded structure of the present invention.
Detailed Description
In order to make the objects and technical solutions of the present invention more clearly understood, the present invention will be described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
The utility model provides an online film cooling device of multilayer coextrusion casting film machine, it includes platform frame 8, between the platform frame of both sides be equipped with preceding deflector roll 7 in proper order, chill roll 3, go up chill roll 4, lower chill roll 6, back deflector roll 5. The roll shafts of the front guide roll, the cooling roll, the upper cooling roll and the lower cooling roll and the back guide roll are all assembled on the platform frames on the two sides, and each guide roll is driven by a motor.
The front guide roller is arranged below the corona machine 2, the cooling roller is close to the front guide roller, the distance between the upper cooling roller and the lower cooling roller is 1.2-1.3 meters, and the rear guide roller is arranged behind the upper cooling roller and the lower cooling roller.
The film 1 passes through the front guide roller, then passes through the cooling roller, then passes through the space between the upper cooling roller and the lower cooling roller, and finally passes through the rear guide roller.
The above examples are merely illustrative for clarity and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. It is not necessary or necessary to exhaustively enumerate all embodiments herein, and obvious variations or modifications can be made without departing from the scope of the invention.
