Description

Technical Field

[0001] This utility model relates to the field of glass annealing technology, and in particular to a glass annealing temperature gradient furnace. Background Technology

[0002] Chinese patent document CN218058808U discloses a glass annealing furnace, including a fixed platform. The upper part of the fixed platform is respectively provided with an annealing furnace body and two fixed plates. A sliding groove is fixedly installed on the side wall of the fixed plate or the annealing furnace body. A slider is slidably installed on the sliding groove, and a first motor is fixedly installed on the slider. One end of a conveying roller is coaxially mounted on the output shaft of the first motor. The other end of the conveying roller extends through a sealing sleeve into the space between the two fixed plates or into the annealing furnace body. This invention allows adjustment of the length of the conveying roller extending into the fixed plate or the annealing furnace body by adjusting the position of the slider on the sliding groove. This results in a smaller contact area between the conveying roller and the glass plate, less heat transfer from the glass plate to the conveying roller during heating, and less temperature drop at the contact point, thus preventing incomplete annealing of the glass plate.

[0003] The glass annealing furnaces described above are not convenient to control the opening of the furnace according to the size of the glass products. If the furnace opening is too large, the heat inside the furnace will be lost too quickly, while if the furnace opening is too small, larger glass products will not be able to enter the furnace, making them inflexible in use.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a glass annealing temperature gradient furnace, comprising a first furnace body 1 and a furnace opening control mechanism 4. A second furnace body 2 is fixedly installed on one side of the first furnace body 1 via a flange ring, and a third furnace body 3 is fixedly installed on one side of the second furnace body 2 via a flange ring. The furnace opening control mechanism 4 is disposed outside the first furnace body 1 and includes a fixing plate 401, a partition plate 402, and a strip-shaped slide 407. Two sets of fixing plates 401 are fixedly installed on the other side of the first furnace body 1 and one side of the third furnace body 3, respectively. The front and rear adjacent sides of the fixing plates 401 are respectively provided with... A set of strip-shaped chutes 407 are attached to a set of partition plates 402 on the other side of the first furnace body 1 and one side of the third furnace body 3 respectively. The front and rear sides of the partition plates 402 are slidably connected to the inner wall of the strip-shaped chutes 407. A set of furnace openings 8 are opened on one side of the first furnace body 1 and the other side of the third furnace body 3 respectively. Support plates 5 are fixedly installed on the front and rear adjacent sides of the fixing plate 401. A set of electric heating tubes 6 are fixedly installed on the inner top of the first furnace body 1, the second furnace body 2 and the third furnace body 3 respectively. Multiple sets of electric ceramic rollers 7 are respectively provided on the front and rear inner walls of the first furnace body 1, the second furnace body 2 and the third furnace body 3.

[0022] Secondly, the furnace opening control mechanism 4 also includes a connecting plate 403, an internal threaded block 404, a threaded rod 405, and an auxiliary knob 406. A connecting plate 403 is fixedly installed on one side of each of the two sets of partition plates 402. The tops of the two sets of connecting plates 403 are rotatably connected to one end of a threaded rod 405. Two sets of internal threaded blocks 404 are fixedly installed on the front and rear adjacent sides of the fixed plate 401. The outer walls of the two sets of threaded rods 405 are respectively connected to the internal threads of the internal threaded blocks 404. An auxiliary knob 406 is fixedly installed on the other end of the threaded rod 405, which can adjust the partition plate 402 by raising and lowering it. This allows for control of the opening degree of the furnace opening 8 according to the size of the glass products, minimizing heat loss from the furnace while ensuring that glass products of various sizes can enter the furnace smoothly, making it more flexible to use.

[0023] Furthermore, the interiors of the first furnace body 1, the second furnace body 2, and the third furnace body 3 are all interconnected. Multiple sets of support rods 9 are fixedly installed at the bottom of the first furnace body 1, the second furnace body 2, and the third furnace body 3, which can be assembled into separate parts.

[0024] Working principle: In use, the flange rings of the first furnace body 1, the second furnace body 2, and the third furnace body 3 are connected by bolts. The number of second furnace bodies 2 is increased or decreased according to the type of glass products. The threaded rod 405 is rotated by the auxiliary knob 406, causing the threaded rod 405 to move downward in the internal thread block 404. Under the limit of the strip slide 407, the connecting plate 403 is pushed to move up and down, thereby driving the partition plate 402 to slide up and down between the strip slide 407. The partition plate 402 blocks the furnace opening 8. According to the size of the glass products, the furnace opening 8 is adjusted to be just large enough for the glass products to pass through. The electric heating tubes 6 are turned on to heat the glass products, and the temperature in the first furnace body 1, the second furnace body 2, and the third furnace body 3 is controlled in a gradient. The glass products are placed on the electric ceramic roller 7 for conveying, passing through the first furnace body 1, the second furnace body 2, and the third furnace body 3 in sequence, so that the glass products are uniformly annealed and then sent out of the device.
