Description

Technical Field

[0001] This utility model relates to the field of glass tempering equipment, and in particular to a support and adjustment structure for a glass heating furnace forming block. Background Technology

[0002] In traditional glass tempering furnaces, pre-drilled forming blocks are typically placed directly on vertically laid ceramic fiber insulation boards. This installation method has significant technical drawbacks: First, because the forming blocks rely entirely on the ceramic fiber board for support, it is difficult to precisely adjust the concentricity between the pre-drilled holes and the ceramic roller conveyor. Once installed, even if misalignment is discovered, it cannot be effectively corrected, leading to friction between the roller conveyor and the hole walls during operation.

[0003] More seriously, ceramic fiber materials undergo thermal shrinkage and collapse deformation under long-term high-temperature operation. This deformation causes the originally horizontally placed molding blocks to gradually tilt, thus generating lateral pressure on the ceramic roller conveyor. On the one hand, this continuous frictional pressure directly damages the roller conveyor surface; on the other hand, the tilted molding blocks hinder the normal rotation of the roller conveyor, causing uneven transmission speed and ultimately forming scratches on the tempered glass surface. The existing installation structure cannot prevent this problem caused by thermal deformation, nor does it have simple and effective adjustment methods. Every time a problem occurs, it requires stopping the machine for cumbersome disassembly and reinstallation, seriously affecting production efficiency and product quality.

[0004] Therefore, there is an urgent need to develop a new type of molded block support and adjustment structure that can effectively overcome the shortcomings of traditional methods and ensure stable support and precise alignment performance in high-temperature environments over a long period of time. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a support and adjustment structure for the forming block of a glass heating furnace, which can effectively avoid the forming block tilting and rubbing against the ceramic roller due to the shrinkage and collapse of the ceramic fiber insulation material caused by heat, thereby causing damage to the surface of the ceramic roller, and the phenomenon of scratches on the surface of tempered glass caused by the forming block tilting and rubbing against the ceramic roller causing it to lose speed.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a support and adjustment structure for a glass heating furnace forming block, comprising a roller conveyor perforated plate and a positioning adjustment assembly for supporting and adjusting the forming block; the roller conveyor perforated plate is generally L-shaped, one side of the forming block is supported on the roller conveyor perforated plate, and the bottom of the other side is supported and fixed by a vertical support plate, a U-shaped guide fixing clip is sleeved on the lower part of the support plate, and a positioning hole is opened at the bottom of the U-shaped guide fixing clip; the positioning adjustment assembly includes an adjusting bolt and an adjusting nut, the adjusting nut is vertically fixed on the bottom plate of the heating furnace, the adjusting bolt passes through the nut and connects to the positioning hole, and the positioning adjustment assembly is used to adjust the height of the support plate to adjust the position of the forming block to ensure concentricity with the ceramic roller conveyor.

[0007] As a preferred embodiment, the system also includes a forming block pull tab, one end of which is fixed to the forming block and the other end is fixed to the support plate for fixing the adjusted forming block; a support pin for lateral reinforcement is provided through the middle of the forming block pull tab.

[0008] As a preferred embodiment, the upper end of the adjusting bolt is provided with a positioning cylinder that mates with the positioning hole at the bottom of the U-shaped guide fixing clip, and the height of the positioning cylinder is the same as the height of the positioning hole.

[0009] As a preferred option, the width of the inner groove of the U-shaped guide fixing card is adapted to the thickness of the support plate.

[0010] As a preferred embodiment, the support plate is a ceramic fiber support plate.

[0011] Based on the above technical solution, the beneficial effects of this utility model are:

[0012] 1. This utility model replaces the traditional pure ceramic fiber soft support with a composite support structure consisting of a perforated metal bending roller conveyor plate and a ceramic fiber support plate. By using rigid support on one side and adjustable support on the other, it effectively solves the problem of molding block tilting caused by thermal shrinkage in traditional pure ceramic fiber supports, significantly improving the overall structural stability. This utility model is low-cost, highly efficient in installation, and eliminates the problem of roller surface damage caused by molding block tilting. It also avoids glass surface scratches caused by roller stalling, greatly improving equipment reliability and service life.

[0013] 2. This utility model achieves precise adjustment of the forming block height through the dual fixing and cooperation design of the positioning adjustment component and the U-shaped guide fixing card, ensuring that the pre-opened hole and the hole of the roller conveyor perforated plate always remain concentric. The adjustment process is simple and quick, which not only ensures the stability of the position after adjustment, but also facilitates daily maintenance and adjustment. Attached Figure Description

[0026] Specifically, the forming block 2 is a pre-drilled forming block, which has a pre-drilled hole that matches the radius of the ceramic roller conveyor 3. The hole diameter is designed to be ΦD+1, where ΦD represents the diameter of the roller conveyor.

[0027] Specifically, the forming block 2 is a pre-drilled forming block, and the size of the opening is adapted to the radius of the roller conveyor.

[0028] In this embodiment, the roller conveyor perforated plate 1 adopts an integral welded structure, and is L-shaped overall. Its vertical surface is connected to the horizontal plate by welding. Specifically, the height of the vertical surface of the roller conveyor perforated plate 1 is the same as the height of the pre-drilled forming block 2.

[0029] The bottom of the furnace wall is covered with an insulation board as an installation reference, and the pre-drilled forming block 2 is set on the insulation board. The forming block 2 adopts a composite support structure. One side of the forming block 2 is supported on the roller conveyor perforated plate 1, and the bottom of the other side is supported and fixed by a vertical support plate 5. A U-shaped guide fixing clip 6 is sleeved on the lower part of the support plate 5, and a positioning hole is opened at the bottom of the U-shaped guide fixing clip 6.

[0030] The positioning adjustment assembly 7 includes an adjusting bolt 701 and an adjusting nut 702. The adjusting nut 702 is vertically fixed to the bottom plate of the heating furnace. The adjusting bolt 701 passes through the nut 702 and connects to the positioning hole.

Specifically, the adjusting nut 702 is fixed to the bottom plate to restrict the retraction and loosening of the adjusting bolt 701. The length of the adjusting bolt 701 is greater than the thickness of the bottom insulation layer inside the furnace.

[0031] The forming block pull tab 4 has one end fixed to the forming block 2 and the other end fixed to the support plate 5, used to fix the adjusted forming block 2. In this embodiment, the two ends of the forming block pull tab 4 are connected to the forming block 2 and the support plate 5 by bolts. A through-type support nail is added to the middle of the forming block pull tab 4 for lateral reinforcement. The support nail penetrates the insulation layer, with one end fixed to the forming pull tab 4 and the other end fixed to the furnace body.

[0032] The upper end of the adjusting bolt 701 is provided with a positioning cylinder that mates with the bottom positioning hole of the U-shaped guide fixing clip 6, and the height of the positioning cylinder is the same as the height of the positioning hole.

[0033] Specifically, the width of the inner groove of the U-shaped guide fixing card 6 is adapted to the thickness of the support plate 5.

[0034] In this embodiment, the support plate 5 is a ceramic fiber support plate.

[0035] How to use this utility model:

[0036] When the molding block tilts due to the thermal shrinkage and collapse of the insulation material, rotate the adjusting bolt 701 to move the U-shaped guide fixing clip 6 upward along the axial direction of the adjusting bolt 701, thereby raising the height of the molding block 2. Observe the concentricity of the pre-drilled hole of the molding block and the ceramic roller conveyor 3 to ensure that they are aligned. After adjustment, use the molding block pull tab 4 to further fix the molding block 2 and the support plate 5 to ensure long-term stability. If the position of the molding block 2 shifts again due to thermal deformation or wear, the adjusting bolt 701 can be rotated again to correct the position of the molding block without disassembling other parts.
