Description

Technical Field

[0002] During the production process of the film, the raw material is heated and melted and then discharged through the casting machine. The discharged molten material flows to the surface of the cooling roller and is quickly cooled to form a film. The patent announcement number is 202022532334.7, which discloses a CPP cast film bidirectional water flow cooling roller structure, including a cooling roller body, and slide grooves are opened on the left and right sides of the inner cavity of the cooling roller body. The middle part of the cooling roller body is movably connected with a water inlet pipe, and support frames are fixedly installed on both ends of the water inlet pipe. The utility model installs a water collecting trough at the top of the water inlet pipe through a connecting pipe. After the cooling water enters the water inlet pipe from the right end of the water inlet pipe, the cooling water is sent into the water collecting trough through multiple connecting pipes. When the cooling roller body rotates, the inner wall of the cooling roller body contacts the cooling water at the top of the inner cavity of the water collecting trough, so that the top of the cooling roller body is cooled, so that the temperature distribution of the cooling water in the water collecting trough on the axis of the cooling roller body is uniform, thereby avoiding a large temperature difference on the surface of the cooling roller body and improving the rapid cooling film quality of the cast film.

[0003] The above-mentioned prior art solution has the following defects: there is only a single water collecting tank inside the cooling roller, and the water output of the single water collecting tank is limited. When the cooling roller needs to be cooled rapidly, the amount of cooling water provided by the single water collecting tank is limited, resulting in the cooling roller being unable to lower its temperature rapidly, thereby reducing the cooling efficiency of the cooling roller.

When the cooling roller needs to be cooled rapidly, the amount of cooling water provided by the single water collection tank is limited, resulting in the cooling roller being unable to lower the temperature rapidly, thereby reducing the cooling efficiency of the cooling roller.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a CPP cast film bidirectional water flow cooling roller structure, comprising a cooling roller body, a main water pipe is arranged inside the cooling roller body, both sides of the main water pipe extend to both sides of the cooling roller body, the surface of the main water pipe is connected with a water branch pipe group, the number of the water branch pipe groups is four, and the four water branch pipe groups are distributed at equal distances, the side of the water branch pipe group away from the main water pipe is connected with a water spray plate, and both sides of the surface of the main water pipe are fixedly connected with cross brackets.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 3 As shown, the utility model provides a CPP cast film bidirectional water flow cooling roller structure, including a cooling roller body 1, a main water pipe 2 is arranged inside the cooling roller body 1, both sides of the main water pipe 2 extend to both sides of the cooling roller body 1, the surface of the main water pipe 2 is connected with a branch water pipe group 3, the number of the branch water pipe groups 3 is four, and the four branch water pipe groups 3 are distributed at equal distances, the side of the branch water pipe group 3 away from the main water pipe 2 is connected with a water spray plate 4, and both sides of the surface of the main water pipe 2 are fixedly connected with a cross bracket 5.

[0021] refer to Figure 3 A pulley 6 is rotatably connected to the side of the cross bracket 5 away from the main water pipe 2 , and the surface of the pulley 6 contacts the inner wall of the cooling roller body 1 .

[0022] As a technical optimization solution of the utility model, by setting the pulley 6, the cross bracket 5 can be isolated from contact with the cooling roller body 1, avoiding the surface friction between the cooling roller body 1 and the cross bracket 5 when moving, causing the surface of the cross bracket 5 to be worn, thereby improving the installation safety of the cross bracket 5.

[0023] refer to Figure 3 Both sides of the inner side of the water spray plate 4 are fixedly connected with reinforcement plates 7, and the surface of the reinforcement plate 7 is fixedly connected to the surface of the cross bracket 5.

[0024] As a technical optimization solution of the utility model, by setting a reinforcement plate 7, the connection between the water spray plate 4 and the cross bracket 5 can be reinforced to avoid breakage of the water spray plate 4 and the cross bracket 5 during use, to prevent the water spray plate 4 and the cross bracket 5 from failing to cooperate, and to improve the use effect of the water spray plate 4 and the cross bracket 5.

[0025] refer to Figure 3 A water permeable port 8 is provided on the surface of the reinforcing plate 7 , and the water permeable port 8 is located inside the cooling roller body 1 .

[0026] As a technical optimization solution of the utility model, by providing the water permeable port 8, the rotation resistance of the reinforcing plate 7 can be reduced, avoiding a large contact area between the reinforcing plate 7 and water, resulting in water flow being blocked, and improving the fluidity of the cooling water flow.

[0027] refer to Figure 3 Both sides of the reinforcing plate 7 are fixedly connected with reinforcing ribs 9 , and the reinforcing ribs 9 are located inside the cooling roller body 1 .

[0028] As a technical optimization solution of the utility model, by setting the reinforcing ribs 9, the structural strength of the reinforcing plate 7 can be strengthened, so as to avoid deformation of the reinforcing plate 7 during long-term use, which would cause the reinforcing plate 7 to be unable to be used normally, thereby improving the use stability of the reinforcing plate 7.

[0029] refer to Figure 3 A reinforcing member 10 is fixedly connected to the surface of the reinforcing plate 7 , and a surface of the reinforcing member 10 is fixedly connected to the surface of the cross bracket 5 .

[0030] As a technical optimization solution of the utility model, by setting a reinforcement piece 10, the connection between the reinforcement plate 7 and the cross bracket 5 can be reinforced to avoid breakage of the reinforcement plate 7 and the cross bracket 5 during use, to prevent the reinforcement plate 7 and the cross bracket 5 from failing to cooperate, and to improve the use effect of the reinforcement plate 7 and the cross bracket 5.

[0031] refer to Figure 2 There are four water spray plates 4 , and the water spray plates 4 are located at the front and rear sides of the top and bottom inside the cooling roller body 1 .

[0032] As a technical optimization solution of the utility model, by setting the number of water spray plates 4 to four, the discharge volume of cooling water can be increased, avoiding the limited supply of cooling water, which causes the cooling roller body 1 to be unable to cool down rapidly, thereby improving the cooling efficiency of the cooling roller body 1.

[0033] The working principle and use process of the utility model are as follows: when in use, the main water pipe 2 is connected to an external water source, the water inside the main water pipe 2 is distributed to the inside of each water branch pipe group 3, the water branch pipe group 3 evenly delivers water to every inch of space inside the water spray plate 4, four water spray plates 4 are evenly distributed inside the cooling roller body 1, the water spray plates 4 supply water at the same time, the cooling roller body 1 can be evenly cooled as a whole, and the cooling roller body 1 will not be locally cooled, thereby having the advantages of efficient and rapid cooling.

[0034] To sum up: the CPP cast film bidirectional water flow cooling roller structure, through the coordinated use of the cooling roller body 1, the main water pipe 2, the water distribution pipe group 3, the water spray plate 4 and the cross bracket 5, solves the problem that there is only a single water collecting tank inside the cooling roller, and the water output of the single water collecting tank is limited. When the cooling roller needs to be cooled rapidly, the cooling water volume provided by the single water collecting tank is limited, resulting in the cooling roller being unable to reduce the temperature rapidly, thereby reducing the cooling efficiency of the cooling roller.
