[0064] As a preferred option, such as Figures 1-3 As shown, each surface of the brick 2 is restrained by the alloy body 1.

[0065] Preferably, the two lateral sides of the second part 12 cooperate to limit the brick body 2 laterally; the two vertical sides of the second part 12 cooperate to limit the brick body 2 vertically; and the first part 11 and the third part 13 cooperate to limit the brick body 2 longitudinally.

The second side plate A121 and the second side plate B122 cooperate to limit the two lateral sides of the brick body 2, and the second top plate 123 and the second bottom plate 124 cooperate to limit the two vertical sides of the brick body 2.

[0067] Preferably, the third part 13 further includes a third top plate 133 and a third bottom plate 134 arranged vertically opposite each other, and a longitudinal side plate 135 connected to the longitudinal rear end of the third side plate A131 and the third side plate B132, wherein a wire through hole 130 is provided at the lower part of the longitudinal side plate 135.

[0068] Preferably, the pointed corner A110 of the first part 11 cooperates with the second part 12 to laterally limit the brick body 2.

It also includes a first side plate C115 that completely blocks the longitudinal side of the frame structure away from the brick body 2, and a first side plate D116 that partially blocks the longitudinal side of the frame structure facing the brick body 2. The horizontal end of the first bottom plate 114, the horizontal end of the first side plate C115, the first side plate B112, and the first side plate D116 together form a sharp corner A110. A limiting step 213 is provided at the corner of the brick body 2 that connects to the sharp corner A110.

[0071] Example 3

[0072] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0073] like Figure 3 , Figure 6 As shown, preferably, it also includes a heating unit 3, which is installed on the brick body 2 and at least the working part 301 is accommodated in the heating space. The portion of the heating space that is adapted to the upper and lower calendering rollers has a sharp corner A110, and the working part 301 is shaped similarly to the heating space.

[0074] In this embodiment, a refractory brick body 2 is matched and limited within the alloy body 1. The alloy body 1 has a steel sharp corner A110 that can match and conform to the contours of the upper and lower calendering rolls, thereby effectively preventing edge crystallization during glass calendering. Furthermore, an irregularly shaped heating unit 3 is matched to the alloy body 1 with the sharp corners, so that the heating unit 3 can cover the sharp corner heating space on the working surface of the alloy body 1, thereby achieving sufficient and uniform heating and heat preservation of the edge of the baffle brick, thereby controlling and reducing the lateral temperature difference in front of the calendering roll during glass forming as much as possible, ensuring the glass forming quality and yield. Therefore, the overall structural design of the baffle brick in this embodiment has good practicality and the forming quality of glass products is good when applied to glass calendering production.

[0075] Preferably, the heating unit 3 is shaped to cover the working surface of the alloy body 1.

[0076] In one implementation, the heating unit 3 is configured as an integral structure, that is, a single heating element.

[0077] Preferably, the brick body 2 is configured as a split structure, which includes a quick-installation part A21 that can move laterally. At least the part of the heating unit 3 that is adapted to the pointed corner A110 is installed on the quick-installation part A21 and moves laterally synchronously with the quick-installation part A21 to be removed from the pointed corner A110.

[0078] In this embodiment, a split-structure brick body 2 is set up by further matching the irregularly shaped heating unit 3. It includes a quick-installation part A21 that can move laterally. The part of the heating unit 3 that extends into the heating space in a contoured manner is installed on the quick-installation part A21. Thus, the irregularly shaped heating unit 3 can be quickly moved out and replaced by a combination of lateral movement and lifting of the quick-installation part A21. Therefore, the quick-installation replacement method of the edge brick and the irregularly shaped heating element 3 in this embodiment is ingenious and convenient, which can ensure continuous production efficiency and effectively avoid delaying the production schedule.

[0079] Example 4

[0080] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0081] like Figure 3 , Figure 6 As shown, preferably, the heating unit 3 is configured as a split structure, which includes a first heating element 31 installed on the quick-installation part A21.

The brick body 2 also includes a quick-installation part B22 arranged horizontally alongside the quick-installation part A21. The heating unit 3 also includes a second heating element 32 installed on the quick-installation part B22.

[0082] In this embodiment, by setting the heating unit 3 as a split structure, it can not only fully adapt to the shape of the irregular heating space for arrangement and be adapted to the customized design for edge bricks of different sizes, but also facilitate the replacement of individual heating elements, saving costs.

[0083] As a preferred option, combined with Figure 7As shown, the first heating element 31 and the second heating element 32 both include a working part 301 and a mounting part 302 connected to each other. The quick-release part A21 and the quick-release part B22 are both provided with mounting grooves A211. The mounting part 302 is horizontally arranged and installed in the mounting groove A211.

[0086] As another preferred implementation, such as Figure 5 As shown, the mounting groove A211 is configured as a semi-groove structure formed on the upper surface of the quick-installation part A21.

[0087] In this embodiment, the mounting groove A211 is configured as a semi-groove structure formed on the upper wall of the quick-installation part A21, thereby supporting and effectively accommodating the straight rod-shaped mounting part 302. Typically, the heating unit 3 uses a silicon carbide rod or a silicon molybdenum rod. The structure of this embodiment can effectively prevent the silicon carbide rod or silicon molybdenum rod from being worn down and falling off, causing electrical conductivity and affecting the safety of personnel and equipment.

[0088] Preferably, a limiting support 5 is provided in the heating space, and the bottom of the working part 301 is limited and installed in the support groove 50 of the limiting support 5 to obtain vertical support and longitudinal limitation.

[0090] Example 5

[0091] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0093] Preferably, the lifting assembly 23 includes a lifting groove 231 formed on the upper surface of the quick-assembly part A21 or the quick-assembly part B22, and a lifting ring 232 arranged around the quick-assembly part A21 or the quick-assembly part B22. After the external hook extends into the lifting groove 231, it hooks the lifting ring 232 to perform the lifting operation.

[0094] In a preferred embodiment, the top structure of the first part 11, the second part 12, and the third part 13 is configured as a top plate 101 integrally formed with each other, that is, the first top plate 113, the second top plate 123, and the third top plate 133 are an integrally formed structure.

[0096] It is worth noting that the use of a single-piece top plate 101 and bottom plate 102 ensures good integrity of the alloy body 1, a stable and reliable structure, and makes it easier and faster to lift the top plate 101 when replacing the heating unit 3.

[0097] Example 6

[0098] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments.

The base part 24 provides positioning support and movement limit for the quick-assembly part, making the brick structure and the quick-assembly operation process stable and reliable, ensuring practicality and effectiveness. Moreover, only a small part of the quick-assembly part needs to be lifted and quick-assembled, while the base part 24 is fixed and does not need to be moved, increasing the convenience of replacement operations and optimizing operational efficiency.

[0101] Preferably, keyway assembly 25 is provided on the connection surface between quick-release part A21 and base part 24 and on the connection surface between quick-release part B22 and base part 24.

[0104] It is worth noting that the brick body 2 is connected by a keyway structure between its various parts, which achieves mutual connection and limitation. Specifically, the keyway assembly 25 guides the lateral movement of the quick-installation parts A21 and B22 and restricts their longitudinal movement relative to the base part 24, thereby ensuring the stability of the overall structure of the edge retaining brick and its reliability during use.

[0105] For the brick 2 with the base portion 24, the specific limiting structure of the alloy body 1 for the brick 2 is as follows:

[0106] The height of the second side plate A121 is adapted to simultaneously limit the lateral movement of the quick-release part B22 and the base part 24; the height of the second side plate B122 is at least adapted to limit the lateral movement of the base part 24; the second top plate 123 limits the top of the quick-release part A21 and the quick-release part B22 vertically; the second bottom plate 124 limits the bottom of the base part 24 vertically; a limiting step 213 is provided at one corner where the base part 24 and the quick-release part A21 connect to the pointed corner A110; the first side plate D116 is matched and locked in the limiting step 213 to simultaneously limit the lateral and longitudinal movement of the quick-release part A21 and the base part 24; the height and position of the third side plate B132 are adapted to cooperate with the first side plate D116 to limit the longitudinal movement of the base part 24 and the quick-release part A21.

[0108] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0109] As another implementation method, such as Figure 1 , Figure 5 As shown, the portion of the brick body 2 that is adapted to the calendering roll has a pointed corner C210. ​​The size of the pointed corner C210 is smaller than the size of the pointed corner A110, thereby forming a step between the two that is adapted to install the calendering roll bushing.

[0110] In this embodiment, the side heights of the sharp corner portions A110 and C210 that directly engage with the calender roll are misaligned, and the structure of this embodiment is adapted to the calender roll structure with bushings.

[0111] Example 7

[0112] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0113] As one implementation method, such as Figure 8 As shown, the portion of the brick body 2 that is adapted to the calendering roll has a sharp corner C210, and the sharp corner C210 has the same size as the sharp corner A110.

[0114] In this embodiment, the height of the side of the sharp corner A110 and the sharp corner C210 that directly engages with the calender roll is consistent, and the structure of this embodiment is adapted to calender roll structures that do not require bushings.

[0115] Work process:

[0116] The composite edge-stopping brick for glass rolling of this utility model has some structures that can be quickly replaced. The specific operation method is as follows:

[0117] When replacing the first heating element 31, first open the top plate 101 of the alloy body 1, and then directly lift out the quick-release part B22 vertically. This leaves a clearance space on one side of the quick-release part A21, and the clearance space is sufficient to allow the first heating element 31 on it to be completely removed from the sharp corner A110 after the quick-release part A21 is moved laterally. The quick-release part A21 is removed by first moving laterally and then lifting vertically, so that the first heating element 31 installed on it can be replaced individually.

[0118] When replacing the second heating element 32, first open the top plate 101 of the alloy body 1, and then directly lift out the quick-release part B22 vertically to replace the second heating element 32 installed on it separately.

[0119] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
