Description
Technical Field
The utility model relates to the technical field of coated paper production, in particular to a cooling roller for coated paper production.
Background
In the production equipment of the coated paper, a cooling roller is generally required to absorb heat and cool and shape the coated paper, so that the product scrapped due to the adhesion of the high-temperature coated paper after being wound is avoided. In order to realize uniform heat absorption of paper, a hollow structure is generally adopted for the cooling roller, a spiral pipeline is arranged in the cooling roller, and high-speed flow of high-pressure cooling water in the spiral pipeline is used for absorbing heat and cooling the paper outside the cooling roller.
However, when the cooling roller is used, cooling water needs to transfer heat with paper through the pipe wall of the spiral pipeline and the inner wall of the cooling roller, so that the heat exchange efficiency of the coated paper is low.
Disclosure of Invention
The utility model aims to overcome the defects and shortcomings of the prior art and provide a cooling roller for producing coated paper.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a chill roll for laminating paper production, including urceolus and interior axle, its innovation point lies in: the cooling device comprises an outer cylinder, an inner shaft, a plurality of water inlets, a plurality of water outlets, a plurality of water drainage channels, a plurality of plugs, a sealing cover, a water pipe, an external thread, a water inlet and a water outlet, wherein the annular cooling flow channel is formed between the outer cylinder and the inner shaft, the water inlets and the water outlets are respectively formed in the left side and the right side of the inner shaft, the plurality of water drainage channels are formed in an annular array in the outer ring of the water inlets and the water outlets and are communicated with the cooling flow channel, the annular plugs are arranged in the left side and the right side of the inner shaft and seal the left side and the right side of the cooling flow channel, the plugs and the inner shaft are integrally formed, the sealing cover is arranged in the left side and the right side of the outer cylinder and the inner shaft, the water pipe is arranged in the center of the sealing cover, and one end of the water pipe is provided with the external thread and is in threaded connection with the water inlets and the water outlets.
Further, the sealing cover and the water delivery pipe are integrally formed.
After the structure is adopted, the utility model has the beneficial effects that:
according to the utility model, the annular cooling flow channel is arranged, so that cooling liquid can directly exchange heat with the coated paper through the outer cylinder, and the cooling efficiency is accelerated.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Reference numerals illustrate:
1 outer cylinder, 2 inner shaft, 3 cooling flow channel, 4 water inlet, 5 water outlet, 6 drainage water channel, 7 plug, 8 sealing cover and 9 water pipe.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be further described in detail below with reference to the accompanying drawings and detailed description. It should be understood that the detailed description is presented by way of example only and is not intended to limit the utility model.
Referring to fig. 1, a chill roll for laminating paper production, including urceolus 1 and interior axle 2, form annular cooling runner 3 between urceolus 1 and the interior axle 2, water inlet 4 and delivery port 5 are offered respectively to interior axle 1's the left and right sides, a plurality of drainage water course 6 and cooling runner 3 intercommunication are offered to the outer lane annular array of water inlet 4 and delivery port 5, interior axle 2's left and right sides sets up annular end cap 7, end cap 7 seals cooling runner 3's left and right sides, end cap 7 and interior axle 2 integrated into one piece, urceolus 1 and interior axle 2's left and right sides all set up sealed lid 8, sealed lid 8's center sets up raceway 9, the one end of raceway 9 possesses the external screw thread, and through external screw thread and water inlet 4 and delivery port 5 threaded connection. Specifically, after the cooling liquid enters from one of the water delivery pipes 9, the cooling liquid enters into the cooling flow channel 3 through the water inlet 4 and the drainage water channel 6, so that the cooling liquid can directly exchange heat with the coated paper through the outer cylinder 1, the cooling efficiency is accelerated, and then the cooling liquid is discharged through the drainage water channel 6, the water outlet 5 and the water delivery pipe 9 at the other end.
In this embodiment, the sealing cover 8 and the water pipe 9 are integrally formed, so that the sealing performance of the sealing cover is improved, and the sealing ring can be added to improve the sealing performance.
The foregoing is merely illustrative of the present utility model and not restrictive, and other modifications and equivalents thereof may occur to those skilled in the art without departing from the spirit and scope of the present utility model.
