Detailed Embodiments

[0033] The present application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention and are not intended to limit the invention. Additionally, it should be noted that for the sake of description, only the parts related to the invention are shown in the drawings.

[0034] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0035] For the sake of clear and concise description of the following embodiments, a brief introduction to the related art is given first:

[0036] In the prior art, a rabbet is used in a float glass production line to stretch the edge of the glass to ensure the size and flatness of the glass. As Figure 1 shown, a traditional rabbet head usually includes a wheel housing 2, an inner water pipe 1 and a dispersion plate 3; when the rabbet is in the working state, the wheels of the rabbet are in direct contact with the glass ribbon and drive the glass ribbon to move forward on the surface of the tin bath. However, due to the high temperature of the glass ribbon, the phenomenon of coiling the head is very likely to occur, that is: during the cooling process of the glass ribbon, thermal expansion and contraction will occur. If the wheels cannot adapt to this temperature change, curling will occur, resulting in curling, folding or other shape defects on the surface of the glass ribbon. This phenomenon will affect the quality of the finished glass and may even cause the production line to stop running in severe cases. Therefore, the following solutions are designed in this application to solve the current defects.

[0037] In order to make the rabbet cooling water anti-backflow device provided by the embodiments of this application clearer and easier to understand, the device will be introduced below with reference to the accompanying drawings. As Figure 2 shown, this figure is a schematic structural diagram of the rabbet cooling water anti-backflow device provided by the embodiments of this application. The device includes:

[0038] An inner water pipe 1, which is arranged inside the wheel housing 2; the inner water pipe 1 and the wheel housing 2 are coaxially arranged and a water circulation channel 4 is formed between the two; here, the inner water pipe 1 has a water inlet end and a water outlet end, and the water inlet end of the inner water pipe 1 is connected to the water supply port of the water supply tank of the rabbet. Here, the inner water pipe 1 can be connected to the rotary joint of the rabbet to support the rotation of the inner water pipe 1.

[0039] A dispersion plate 3, which is arranged at the water outlet end of the inner water pipe 1 and is communicated with the water outlet end; among them, the dispersion plate 3 has a guiding effect on the cooling water led out from the water outlet end of the inner water pipe 1.

[0040] The positioning structure 5 is in a circular shape and is sleeved on the inner water pipe 1 and is arranged near the water outlet end; a sealing structure 6 is annularly arranged on the outer wall of the positioning structure 5, and the sealing structure 6 contacts the inner wall surface of the dispersion plate 3; wherein, the sealing structure 6 is stably installed between the inner water pipe 1 and the dispersion plate 3 through the positioning structure 5, and the gap between the inner water pipe 1 and the dispersion plate 3 is blocked by the contact between the sealing structure and the inner wall surface of the dispersion plate 3, so that the cooling water flowing out from the water outlet end flows along the dispersion plate 3 and the water circulation channel 4, preventing the cooling water from flowing randomly, thereby reducing the probability of water ripples generated on the glass liquid surface when the cooling water converges, thus ensuring the quality of the finished glass. Moreover, improving the cooling water flow can also enhance the cooling effect to prevent the head of the edge roller from sticking with tin and increase the service life of the edge roller wheels; in addition, when the device is in a working state, the sealing structure separates the inner water pipe 1 and the dispersion plate 3, and can also reduce the friction between the inner water pipe 1 and the dispersion plate 3 and eliminate the abnormal noise generated by the friction.

[0041] When the edge roller is in a working state, the cooling water in the inner water pipe 1 flows out through the water outlet end and the dispersion plate 3 and is introduced into the water circulation channel 4, thereby cooling the roller wheels and edge bars of the edge roller.

[0042] Specifically, as Figure 3 and Figure 4 shown, the sealing structure 6 includes:

[0043] A sealing body 61, the sealing body 61 is in a circular shape and is sleeved on the positioning structure 5; a plurality of grooves 62 are formed on the sealing body 61 along its circumferential direction, and the part of the sealing body 61 between two adjacent grooves 62 forms a sealing area, and the sealing area contacts the inner wall surface of the dispersion plate 3; wherein, the sealing body 61 is a high heat-resistant elastomeric composite material, and the specific material can be selected according to actual requirements. Here, the bottom length of the groove 62 is less than the length of the groove opening of the groove 62. Since the sealing body 61 has elasticity, when the device is in a working state, the vibration between the inner water pipe 1 and the dispersion plate 3 is absorbed by the sealing body 61, that is, the vibration acting force acts on the sealing body 61, and the vibration acting force is dispersed through the groove 62, so that the force distribution of the entire sealing structure 6 is more uniform, thereby improving the durability of the structure and reducing the rapid damage of the sealing structure 6 caused by excessive local stress.

[0044] Elastic connectors 63 are located in the grooves 62, and both ends of the elastic connectors 63 are respectively connected to the side walls of the corresponding grooves 62. Among them, since stress concentration may occur at the corner positions of the grooves 62, there is a problem of damage to these areas first, so elastic connectors 63 are arranged inside the grooves 62 to use the elastic connectors 63 to assist in bearing part of the vibration acting force, further reducing the probability of damage to the sealing body 61 and ensuring the service life of the sealing structure 6.

[0045] Here, the number and distribution pattern of the elastic connectors 63 inside each groove 62 are not restricted and can be set according to actual requirements. Moreover, the elastic connector 63 is a high heat-resistant elastic composite material, and the specific material can be selected according to the actual situation.

[0046] Furthermore, as Figure 3 and Figure 4 shown, auxiliary gaskets 64 are provided both in the sealing area and around the notch of the groove 62. Among them, the auxiliary gasket 64 can increase the volume of the sealing body 61. When the positioning structure 5 and the sealing structure 6 are installed between the inner water pipe 1 and the dispersion plate 3, the auxiliary gasket 64 and the sealing body 61 are deformed, and their acting forces act on the inner water pipe 1 and the dispersion plate 3, thereby stably blocking the gap between the inner water pipe 1 and the dispersion plate 3, effectively preventing the cooling water from flowing randomly. And when the device is in the working state, the auxiliary gasket 64 and the dispersion plate 3 are preferentially rubbed to protect the sealing body 61, and to a certain extent, the service life of the sealing body 61 can also be extended.

[0047] In addition, when two sealing structures 6 are installed on the positioning structure 5, a double-layer sealing structure is formed; among them, the double-layer sealing structure can improve the sealing effect between the water pipe 1 and the dispersion plate 3, effectively prevent the cooling water from flowing randomly, and reduce the probability of water ripples on the glass liquid surface caused by the intersection of the cooling water, thereby ensuring the quality of the finished glass.

[0048] Specifically, as Figure 5 and Figure 6 shown, the positioning structure 5 includes:

[0049] A positioning body 51, the positioning body 51 is sleeved on the inner water pipe 1 near the water outlet end; a clamping groove is provided on the outer wall of the positioning body 51 for installing the sealing structure 6; among them, the positioning body 51 is made of a high-temperature resistant material. The clamping groove can be engaged with the inner ring of the sealing body 61, facilitating the fixed installation of the sealing structure 6 on the inner water pipe 1 through the positioning structure 5.

[0050] Clamping plates 52, the number of clamping plates 52 is multiple, and all the clamping plates 52 are arranged on the same side of the positioning body 51 and are evenly distributed along the circumferential direction of the positioning body 51; among them, the type of the clamping plate 52 is, for example, a spring piece.

[0051] When the clamping plates 52 are in the non-working state, the cross-sectional area of the accommodation space formed by all the clamping plates 52 gradually decreases from the side close to the positioning body 51 to the side far from the positioning body 51.

[0052] During assembly, the clamping plate 52 is sleeved on the inner water pipe 1 from the side away from the positioning body 51 and the positioning structure 5 is moved. The clamping plate 52 is squeezed by the inner water pipe 1 and adheres to the side wall of the inner water pipe 1 due to its own acting force, thereby installing the positioning structure 5 on the inner water pipe 1.

[0053] Further, as Figure 5 shown, the device further includes: a locking sleeve 7. The locking sleeve 7 is arranged outside all the clamping plates 52 and is used to assist in restricting the position of the positioning structure 5. To prevent the positioning structure 5 from shifting along the central axis direction of the inner water pipe 1, when assembling the positioning structure 5, the locking sleeve 7 is fixed outside the clamping plate 52 to restrict the position of the positioning structure 5. Here, one side of the locking sleeve 7 is locked by a screw. During use, the screw is unscrewed, the locking sleeve 7 is closely attached to the outer wall of the clamping plate 52, and then the screw is tightened.

[0054] In this application, a positioning structure 5 and a sealing structure 6 are designed at the connection position between the inner water pipe 1 and the dispersion plate 3. On the one hand, the friction between the inner water pipe 1 and the dispersion plate 3 is reduced, and the abnormal noise generated by the friction is eliminated. On the other hand, the gap between the inner water pipe 1 and the dispersion plate 3 is blocked by a flexible sealing method to prevent the cooling water from flowing randomly, reduce the probability of water ripples on the glass liquid surface caused by the intersection of the cooling water, thereby ensuring the quality of the finished glass. Moreover, after improving the flow of the cooling water, the cooling effect can be enhanced to prevent the head of the edge roller from sticking with tin and improve the service life of the edge roller wheels.

[0055] The embodiment of this application also provides an edge roller, including: the above-mentioned edge roller cooling water anti-backflow device. This edge roller has the functions and advantages of the above-mentioned edge roller cooling water anti-backflow device, which will not be elaborated here in detail.

[0056] The above description is only the preferred embodiment of this application and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to the technical solution formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features with similar functions disclosed in this application.
