Description

Technical Field

[0001] This utility model relates to a heat treatment device for special glass. Background Technology

[0002] Patent CN221094026U discloses a special glass heat treatment processing device, in which the special glass is placed on a conveying grid and fed into a box for heat treatment, and the special glass is limited on the conveying grid by a stop bar. In the above structure, the special glass is in direct contact with the conveyor grid. Considering that the conveyor grid needs to withstand high temperatures, it is generally made of metal. As a result, the special glass is prone to uneven heating during the heat treatment process. On the other hand, the smooth surface of the special glass is prone to sliding on the conveyor grid. Once it collides with the front baffle, it is also easy to damage the relatively fragile end corners. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a heat treatment device for special glass, which improves the conveying grid so that the special glass is in an elevated state during heat treatment and limits and protects the four corners of the glass.

[0004] The technical solution of this utility model is: a heat treatment device for special glass, including a conveying grid, on which multiple sets of brackets and multiple sets of limiting frames are arranged at equal intervals; The bottom of the bracket and the limiting frame are respectively provided with connecting seats. The connecting seats are composed of an upper body and a lower body. The bottom surface of the upper body and the top surface of the lower body are respectively provided with cross-shaped slots. The upper body and the lower body are respectively engaged with the top surface and bottom surface of the conveying grid and fixed to each other. The bracket has a frustum-shaped support portion, and the limiting frame has a column with an elastic abutment portion fixed at the upper end of the column.

[0005] Specifically, the elastic abutment part is a columnar or frustum-shaped steel wool ball.

[0006] Specifically, the conveying grid is made by punching holes in a single thin steel plate, and square holes are evenly distributed on the conveying grid.

[0007] Furthermore, a chain is fixed to each side of the conveying grid, and the two chains are respectively connected to the drive wheels on the drive shaft.

[0008] Furthermore, the upper body and the lower body are respectively provided with cross-shaped support arms, and the slots on the upper body and the lower body extend to the ends of each support arm.

[0009] Specifically, the support portion and the upper body of the bracket are integrally formed.

[0010] Specifically, the uprights and upper body of the limiting frame are integrally formed.

[0011] Furthermore, the column has threads, and the elastic abutment part has a screw connection part, which is screwed to the upper end of the column.

[0012] Specifically, the upper body and the lower body are fixed together by multiple screws.

[0013] The beneficial effects of this utility model are as follows: the bracket and the limiting bracket can be arranged and fixed on the conveying grid according to the specifications of the special glass, which can adapt to the placement and limiting of most specifications of special glass during heat treatment; during the heat treatment process, the bracket reduces the contact area between the special glass and the grid, so that the special glass is in an elevated state during the heat treatment process, which can make the special glass heat more evenly; the four limiting brackets abut against the four corners of the special glass respectively, which on the one hand limits the special glass and prevents the special glass from shifting during the heat treatment process, and on the other hand protects the four corners of the special glass.

[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] Combination Figure 1-3 As shown, a heat treatment apparatus for special glass includes a conveying grid 1, on which multiple sets of brackets 2 and multiple sets of limiting brackets 3 are arranged at equal intervals. The bottom of the bracket 2 and the limiting frame 3 are respectively provided with connecting seats. The connecting seats are composed of an upper body 4 and a lower body 5. The bottom surface of the upper body 4 and the top surface of the lower body 5 are respectively provided with cross-shaped slots 6. The upper body 4 and the lower body 5 are respectively engaged with the top and bottom surfaces of the conveying grid 1 and fixed to each other. The bracket 2 has a frustum-shaped support part 7, and the limiting frame 3 has a column 8, with an elastic abutment part 9 fixed at the upper end of the column 8.

[0018] The working principle of the above structure is as follows: First, according to the length and width of the special glass, fix the positions of the bracket 2 and the limiting frame 3 on the conveying grid 1. The special glass is placed on at least three brackets 2, and the four corners of the special glass abut against the elastic abutting parts 9 on the four limiting frames 3 respectively. Then, it is fed into the machine body for heat treatment under the drive of the conveying grid 1.
