Description

Technical Field

[0001] The utility model belongs to the technical field of glass calendering, and particularly relates to a calendering roller device. Background Art

[0002] During the glass production process, the molten glass at high temperature is rolled through the calendering equipment to a constant changing thickness and then rolled to a standard thickness. During the calendering process, the more conventional method is to use a calender to calender the glass, and the calendering rollers on the calendering machine are used to calender the glass.

[0003] Therefore, the calendering roller is in contact with the high-temperature glass material for a long time. Not only is the temperature of the roller body relatively high, but also due to the high temperature, the roller body expands greatly. As a result, during the calendering process, the thermal expansion causes the roller pressure between the glass to be unable to maintain accuracy, resulting in uneven thickness of the rolled glass. If the thermal expansion is relatively large, the calendering force is large and the glass thickness becomes smaller. Otherwise, the glass thickness is relatively large.

[0004] Therefore, in order to solve this problem, the more common practice is to use water cooling to cool the roller body. Specifically, a water inlet pipe is installed on the roller body to enter the roller body, and hot water is discharged through the water outlet pipe on the roller body to achieve cooling by circulating water.

[0005] However, the disadvantages of this method are also very obvious. Specifically, water forms steam in the high-temperature roller body. Under the action of steam pressure, the water pressure of the drainage inside the roller body is unstable. Therefore, when the drainage speed is constantly changing, the water pipe in the roller body is prone to form a cavity, which causes the center of gravity of the entire roller body to change. After the center of gravity of the roller rolled on the glass changes, the stability of the rolling is greatly reduced. Secondly, during the rolling process, the rolling force on the glass varies greatly. This is reflected in the rolling process. Due to the change in the center of gravity of the roller body, the thickness of the rolled glass is uneven, such as the rolling force is large in the heavy part, and the rolling force is small in the light part.

[0006] In addition, during the process of discharging hot water, due to the water pressure and the assistance of high-temperature steam, the discharged hot water is easy to splash, and it is very easy to splash onto the staff or work equipment during the work process, thus posing a potential safety hazard to production.

[0007] Based on the above background, the purpose of the utility model is to provide a calendering roller device.

[0008] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0009] A calendering roller device, comprising a calendering roller body, the calendering roller body being equipped with a water outlet mechanism, the water outlet mechanism comprising an inner water pipe located inside the calendering roller body, the inner water pipe being equipped with a slow flow component located outside the calendering roller body, the slow flow component comprising an outer water pipe equipped with and connected to the inner water pipe;

[0010] The external water pipe is connected with a connecting pipe, and the connecting pipe is connected with a water tank;

[0011] A water divider component for buffering water flow is provided between the external water pipe and the water tank, and the water divider component includes a water divider plate fixedly connected to the water tank, and the water divider plate is provided with a plurality of water inlet holes connected to the water tank, and a conical water guide is fixedly connected to the water divider plate;

[0013] Preferably, the conical water guide is in the shape of a cone;

[0014] The connecting pipe is in a conical shape;

[0015] The conical water guide is located in the conical tube cavity of the connecting pipe.

[0016] Preferably, the water outlet end of the water tank is equipped with an overflow assembly.

[0017] Preferably, the overflow assembly comprises a conical water outlet pipe assembled and connected to the water tank, and the water outlet pipe of the conical water outlet pipe is fixedly assembled and connected with an overflow water outlet plate.

[0018] Preferably, the overflow outlet plate is provided with a plurality of overflow outlet holes.

[0022] Preferably, the water tank is cylindrical in shape.

[0023] The utility model has the following beneficial effects:

[0024] 1. During the working process, when the water flow with a large speed change enters the outer water pipe from the inner water pipe, the water flows through the water divider component. Under the action of the water divider component, the speed of the water flow is initially buffered. During the buffering process, the water flow with uneven flow velocity is damped and slowed down to a gentle state, and then enters the water tank from the water inlet hole on the water divider plate to continue buffering. Under this mode, because the water tank, water divider component, inner water pipe and outer water pipe are in a connected structure, therefore, under the buffering mode, the drainage is slow and the drainage speed is slow, resulting in the water flow in the inner water pipe being fully filled in the pipe, and it is not easy to have gaps in the pipe, resulting in the defects of reduced stability of roller movement and reduced precision of calendering.

[0025] 2. During operation, under the damping of the overflow water plate, the water flow speed is further reduced to a gentle state and discharged from the overflow water outlet hole on the overflow water plate. In this way, the speed of water discharge from the roller body under high temperature is further reduced and the gentleness of water discharge is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Example 1

[0038] like Figure 1-6 As shown, a calendering roller device includes a calendering roller body 1 (the calendering roller body 1 is a calendering roller used on an existing calendering machine), and a water outlet mechanism 2 is assembled and connected to the calendering roller body 1. The water outlet mechanism 2 includes an inner water pipe 12 located in the calendering roller body 1, and at the same time, the calendering roller body 1 is connected with a water inlet pipe 11, which is used to pass cooling water into the calendering roller body 1, and because the water inlet pipe 11 is connected to the inner water pipe 12, high-temperature water is output from the inner water pipe 12 to the outside.

[0039] Since the high-temperature water in the pipeline generates water vapor, the water flow velocity changes greatly under the action of vapor pressure, resulting in cavity positions inside the pipeline during drainage (that is, the water flow velocity changes too much, resulting in the water flow being unable to completely fill the pipeline, causing gaps to form in the pipeline), and when water is discharged, the air pressure changes significantly, resulting in high-temperature water splashing. The water outlet end of the above-mentioned inner water pipe 12 is equipped with a slow-flow component located outside the calendering roller body 1, and the slow-flow component includes an outer water pipe 21 that is equipped with and connected to the inner water pipe 12.

[0040] The external water pipe 21 is connected with a connecting pipe 22 , and the connecting pipe 22 is connected with a water tank 23 .

[0041] Specifically, the water tank 23 is designed to initially temporarily store the high-temperature sprayed water, forming a buffer in the process.

[0042] Secondly, a water divider component for buffering water flow is provided between the external water pipe 21 and the water tank 23, and the water divider component includes a water divider plate 26 fixedly connected to the water tank 23, and the water divider plate 26 is provided with a plurality of water inlet holes 261 connected to the water tank 23, and a conical water guide 27 is fixedly connected to the water divider plate 26; the conical water guide 27 is located in the tube cavity of the connecting pipe 22.

[0043] Specifically, the conical water guide 27 is in the shape of a cone; the corresponding connecting pipe 22 is in the shape of a cone. The conical water guide 27 is located in the conical tube cavity of the connecting pipe 22. Specifically, a mounting hole is provided on the water tank 23, and the water dividing plate 26 is fixedly connected in the mounting hole; the pipe mouth of the connecting pipe 22 is fixedly connected to the right side wall of the water tank 23, and the pipe mouth fixing part of the connecting pipe 22 is located at the edge of the mounting hole (the shape of the water tank 23 is cylindrical).

[0044] During operation, when the water flow with a large speed change enters the outer water pipe 21 from the inner water pipe 12, the water flow passes through the water divider component. Under the action of the water divider component, the speed of the water flow is initially buffered. During the buffering process, the water flow with uneven flow velocity is damped and slowed down to a gentle state, and then enters the water tank 23 from the water inlet hole on the water divider plate 26 to continue buffering. Under this mode, because the water tank 23, the water divider component, the inner water pipe 12, and the outer water pipe 21 are in a connected structure, therefore, under the buffering mode, the drainage is slow and the drainage speed is slow, resulting in the water flow in the inner water pipe 12 being completely filled in the pipeline, and it is not easy to have gaps in the pipeline, resulting in the defects of reduced stability of roller movement and reduced precision of calendering.

[0045] Example 2

[0046] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 1, the water outlet end of the water tank 23 is equipped with an overflow component.

[0047] Specifically, the overflow assembly includes a conical water guide 24 connected to the water tank 23, and the outlet pipe of the conical water guide 24 is fixedly connected to an overflow water outlet plate 25. The overflow water outlet plate 25 is provided with a plurality of overflow water outlet holes 251.

[0048] Specifically, the conical water guide 24 is connected to the water tank 23 by means of a flange. Specifically, the water outlet end of the water tank 23 is connected with a water outlet connecting pipe 22, and the water outlet end of the water outlet connecting pipe 22 is connected to the water inlet end of the conical water guide 24 by means of a flange.

[0049] During operation, under the damping of the overflow water outlet plate 24, the water flow speed is further reduced to a gentle state and discharged from the overflow water outlet hole 241 on the overflow water outlet plate 24. In this way, the speed of water discharge from the roller body at high temperature is further reduced and the gentleness of water discharge is improved.

[0050] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
