Abstract
The utility model discloses a comdenstion water remove device on coating machine chill roll surface, its characterized in that: the cooling roll water decanting device comprises a water decanting cover which is hermetically buckled on the outer surface of a cooling roll, and the edge contour of the lower part of the water decanting cover, which is jointed with the cooling roll, is of an arc line structure with a low middle part and two high sides. The utility model discloses in strain water cover through lower edge middle low both sides high arc structure for the drop of water that the condensation produced can be when being strickleed off by straining the water cover on the chill roll, quick along this arc lower edge row to both sides, thereby avoided the comdenstion water at the chill roll and strain the long-pending stay between the water cover.
Description
Technical Field
The utility model relates to a film production facility field, especially a comdenstion water remove device on coating machine chill roll surface.
Background
In the production of films, chill rolls are often used. The film is hot after being dried, and the film needs to be sufficiently cooled by a cooling roller to reduce the deformation of the product after being rolled. The existing cooling roller generally adopts a single-pass cooling or double-pass cooling structure, and cooling liquid is introduced into a cooling medium flow passage in the cooling roller, so that the effect of rapidly cooling a film is achieved. However, when the temperature difference between the cooling roller and the external environment is too large, water drops are often condensed on the surface of the cooling roller, and the water drops are stained on the film in the process of cooling the film, so that the quality of the film is seriously affected.
SUMMERY OF THE UTILITY MODEL
The utility model provides a comdenstion water remove device on coating machine chill roll surface can the produced drop of water of the produced condensation of the chill roll surface of efficient removal.
In order to realize the technical effect, the technical scheme of the utility model is as follows:
the condensed water removing device comprises a water decanting cover which is hermetically buckled on the outer surface of the cooling roller, and the edge contour of the lower part of the water decanting cover, which is jointed with the cooling roller, is of an arc line structure with a low middle part and two high sides.
Furthermore, an air nozzle which is right opposite to the cooling roller is arranged in the water decanting cover, the air nozzle is communicated with the air inlet pipe, and at least one air outlet pipe opening is arranged on the end face of the water decanting cover.
Further, the air nozzle and the lower edge of the water decanting cover have the same bending radian.
Furthermore, a water absorption cotton sliver is arranged inside the water decanting cover, and is arranged on the upper edge of the water decanting cover and attached to the surface of the cooling roller.
The utility model has the advantages that: the decanting cover is provided with an arc structure with a lower edge and lower middle parts and two higher sides, so that water drops generated by condensation on the cooling roller can be quickly discharged to two sides along the arc lower edge while being scraped by the decanting cover, and the accumulation of condensed water between the cooling roller and the decanting cover is avoided. And set up the tuyere in decanting the water cover, then can weather the processing to remaining the hydrone that is difficult for decanting on the chill roll surface, promoted the utility model discloses to chill roll surface drying's effect. Meanwhile, the water absorbing cotton sliver arranged in the water decanting cover can promote the dewatering and drying effect of the utility model once again.

fig. 2 is a schematic structural diagram of the present invention.
Reference numerals: 1. the cooling roller 2, the water decanting cover 3, the air nozzle 4, the air inlet pipe 5, the air outlet pipe opening 6 and the absorbent cotton sliver.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The device for removing condensed water on the surface of the cooling roller of the coating machine as shown in fig. 1 and fig. 2 comprises a water decanting cover 2 which is hermetically buckled on the outer surface of the cooling roller 1, wherein the water decanting cover 2 and the cooling roller 1 are in a sliding fit relationship, and in detail, the cooling roller 1 can rotate relative to the water decanting cover. Meanwhile, the edge contour line of the lower part of the decanting cover and the cooling roller is integrally of an upward-tilting arc structure with a low middle and high two sides.
In the present embodiment, it is preferable that a cavity is provided inside the decanting water cover 2, a tuyere 3 is provided in the cavity, which is directed against the surface of the cold zone roller 1, and the rear side of the tuyere 3 is connected to an air inlet pipe 4, wherein the air inlet pipe 4 is connected to an external compressed air generating device. And at least one air outlet pipe opening 5 is arranged on the end surface of the water decanting cover.
In addition to this embodiment, it is preferable that the air volume received by the surface of the cooling roll is equal, and the radian of the outer ring of the air nozzle 3 is equal to that of the lower edge of the decanting cover.
On the basis of the present embodiment, it is preferable that a strip of absorbent cotton sliver 6 is further disposed inside the decanting water cover 2, and it is preferable that the absorbent cotton sliver is mounted along the upper edge of the decanting water cover 2 attached to the cooling roller, and it is ensured that the absorbent cotton sliver itself is also attached to the cooling roller.
The utility model discloses a theory of operation does: when condensed water drops appear on the surface of the cooling roller 1, the rotating cooling roller 1 is scraped by the edge contour lines with the lower middle part and the higher two sides when passing through the lower edge of the water decanting cover 2, and the scraped condensed water can flow to the two sides along the radian of the lower edge contour lines, so that a part of the condensed water still remains in the middle part of the water scraping plate and cannot be discharged like a common water scraping plate. Meanwhile, the condensation roller after moisture removal enters the interior of the decanting water cover 1, and takes away the moisture remaining on the surface of the decanting water cover under the action of the drying air blown out from the air nozzle in the decanting water cover. Finally, the surface of the cooling roller is dried once under the action of the washing cotton sliver when the cooling roller is rotated out of the water decanting cover. Thereby achieving the best effect of removing the condensed water on the surface of the cooling roller.
