Description

Technical Field

[0001] This utility model relates to the field of tempering furnace technology, specifically a high-temperature tempering furnace for glass tableware. Background Technology

[0002] A glass tempering furnace is an industrial heating device primarily used in the deep processing of glass. It employs physical or chemical methods to form a compressive stress layer on the glass surface and a tensile stress layer internally, thereby improving the glass's strength and heat resistance. During operation, the tempering furnace heats the glass to near its softening point (approximately 650°C) and then rapidly cools it, creating compressive stress on the glass surface and tensile stress in the inner layer, resulting in a uniform internal stress distribution. This enhances the glass's bending and impact resistance.

[0003] Current glass tempering furnaces generally use physical heating methods, which heat the glass to near its softening point and then rapidly cool it with air. Compared to a solid piece of glass, glass tableware is relatively light, especially some lighter tableware. During the rapid cooling process, the high-speed airflow can cause the glass tableware to move, and the tableware may collide with each other, causing damage. Therefore, a high-temperature tempering furnace for glass tableware is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature tempering furnace for glass tableware, so as to solve the problem that airflow causes glass tableware to move in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature tempering furnace for glass tableware, comprising a tempering furnace body, an equipment base installed at the bottom of the tempering furnace body, a fan fixedly installed at the upper end of the tempering furnace body, a main pipe connected to the fan, a conveyor belt installed inside the tempering furnace body, and a lifting mechanism provided at the outlet of the tempering furnace body. The lifting mechanism includes a positioning bracket fixedly installed inside the tempering furnace body, positioning guide rods fixedly installed at both ends of the positioning bracket, and a protective device fixedly installed at the lower end of the positioning guide rods. The cap is removed. A lifting beam is movably mounted on the positioning guide rod. A cylinder is fixedly mounted on the positioning bracket. The output end of the cylinder is connected to the lifting beam. A blowing assembly is connected to the lifting beam. The blowing assembly includes a limiting pressure rod fixedly mounted on the lifting beam. A blowing nozzle is movably mounted on the limiting pressure rod. An air inlet is opened on the blowing nozzle. A return spring is provided inside the limiting pressure rod. A telescopic rod is movably mounted inside the limiting pressure rod. A pressure block is fixedly mounted at the lower end of the telescopic rod. The telescopic rod can drive the pressure block to move up and down.

[0006] Preferably, the positioning bracket is provided with a fixed support foot, and the fixed support foot is provided with a bolt, and the fixed support foot is fixed to the outlet of the tempering furnace body by the bolt.

[0007] Preferably, the lifting beam has a movable hole, and the lifting beam is movably mounted on the positioning guide rod through the movable hole, and the cylinder can drive the lifting beam to move up and down.

[0008] Preferably, the lifting beam is restricted to move on the positioning guide rod by an anti-detachment cap, and the lifting beam is movably installed at the outlet of the tempering furnace body by a cylinder, and the lifting beam can drive the limiting pressure rod to move up and down.

[0009] Preferably, a docking sleeve is fixedly installed on the blowing nozzle, and an adjusting screw is connected to the docking sleeve, so that the blowing nozzle can blow out a high-speed airflow.

[0010] Preferably, the docking sleeve has a threaded hole, and the adjusting screw is connected to the docking sleeve through the threaded hole.

[0011] Preferably, the docking sleeve is fixed to the limiting pressure rod by adjusting screws. The limiting pressure rod has a movable groove at its bottom. The telescopic rod is movably installed on the limiting pressure rod through the movable groove. One end of the return spring is fixed to the telescopic rod, and the other end of the return spring is fixed to the bottom of the movable groove. The return spring provides elastic force to the telescopic rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this application, after the glass tableware is pressed onto the conveyor belt, the fan can be started to allow high-speed airflow to be discharged through the main pipe. The high-speed airflow discharged from the main pipe will enter the blow nozzle, and the high-speed airflow entering the blow nozzle will blow onto the glass tableware, causing the glass tableware to cool rapidly. This will generate compressive stress on the surface of the glass tableware and tensile stress in the inner layer, forming a uniform internal stress distribution, thereby improving the glass's bending and impact resistance.

[0014] In this application, after the glass tableware is conveyed to the outlet of the tempering furnace body, the cylinder can be controlled to extend, thereby driving the lifting beam to move downward. After the lifting beam moves downward, it will drive the limiting pressure rod to move downward. After the limiting pressure rod moves downward, it will drive the pressure block to move downward, so that the pressure block abuts against the glass tableware, thereby pressing the glass tableware tightly on the conveyor belt, preventing the glass tableware from being blown away by the high-speed airflow, and reducing the risk of the glass tableware colliding with each other.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a high-temperature tempering furnace for glass tableware, including a tempering furnace body 2, an equipment base 1 installed at the bottom of the tempering furnace body 2, a fan 3 fixedly installed at the upper end of the tempering furnace body 2, a main pipe 4 connected to the fan 3, a conveyor belt 5 installed inside the tempering furnace body 2, a lifting mechanism 6 provided at the outlet of the tempering furnace body 2, and a blowing assembly 7 connected to the lifting beam 604. During the cooling process of the tableware, the pressure block 708 can fix the glass tableware, thereby preventing the glass tableware from being blown by the high-speed airflow and reducing the risk of the glass tableware colliding with each other.

[0022] like Figure 2 and Figure 3 As shown, the lifting mechanism 6 includes a positioning bracket 601 fixedly installed inside the tempering furnace body 2. Positioning guide rods 605 are fixedly installed at both ends of the positioning bracket 601. Anti-detachment caps 606 are fixedly installed at the lower end of the positioning guide rods 605. A lifting beam 604 is movably installed on the positioning guide rods 605. A cylinder 603 is fixedly installed on the positioning bracket 601. The output end of the cylinder 603 is connected to the lifting beam 604. The positioning bracket 601 is provided with a fixed support foot 602, and the fixed support foot 602 is provided with bolts. The fixed support foot 602 is fixed to the outlet of the tempering furnace body 2 by bolts. The lifting beam 604 is provided with a movable hole, and the lifting beam 604 is movably installed on the positioning guide rods 605 through the movable hole.

[0023] Specifically, after the glass tableware is conveyed to the outlet of the tempering furnace body 2, the cylinder 603 can be extended, thereby driving the lifting beam 604 to move downward. After the lifting beam 604 moves downward, it will drive the limiting pressure rod 703 to move downward. After the limiting pressure rod 703 moves downward, it will drive the pressure block 708 to move downward, so that the pressure block 708 abuts against the glass tableware, thereby pressing the glass tableware tightly on the conveyor belt 5, preventing the glass tableware from being blown away by the high-speed airflow, and reducing the risk of the glass tableware colliding with each other.

[0024] like Figure 2 and Figure 4 As shown, the blowing assembly 7 includes a limiting pressure rod 703 fixedly installed on the lifting beam 604, a blowing nozzle 701 movably installed on the limiting pressure rod 703, an air inlet 704 opened on the blowing nozzle 701, a return spring 707 provided inside the limiting pressure rod 703, a telescopic rod 706 movably installed inside the limiting pressure rod 703, a pressure block 708 fixedly installed at the lower end of the telescopic rod 706, a docking sleeve 702 fixedly installed on the blowing nozzle 701, an adjusting screw 705 connected to the docking sleeve 702, a threaded hole opened on the docking sleeve 702, and the adjusting screw 705 connected to the docking sleeve 702 through the threaded hole. An air supply pipe is provided on the air inlet 704, and the air supply pipe is connected to the main pipe 4.

[0025] Specifically, after the glass tableware is pressed onto the conveyor belt 5, the fan 3 can be started to discharge high-speed airflow through the main pipe 4. The high-speed airflow discharged from the main pipe 4 will enter the blow nozzle 701. The high-speed airflow entering the blow nozzle 701 will blow onto the glass tableware, causing the glass tableware to cool down rapidly. This will generate compressive stress on the surface of the glass tableware and tensile stress in the inner layer, forming a uniform internal stress distribution, thereby improving the glass's bending and impact resistance.

[0026] Working principle: During operation, the glass tableware is first transported to the tempering furnace body 2 via conveyor belt 5 for heating. After heating, the tableware is transported to the outlet of the tempering furnace body 2 via conveyor belt 5. Once at the outlet, cylinder 603 extends, causing the lifting beam 604 to move downwards. This movement in turn causes the limiting rod 703 to move downwards, which in turn causes the pressing block 708 to move downwards, pressing it against the glass tableware and thus securing it firmly. After the glass tableware is pressed onto the conveyor belt 5, the fan 3 can be started to discharge high-speed airflow through the main pipe 4. The high-speed airflow discharged through the main pipe 4 will enter the blow nozzle 701. The high-speed airflow entering the blow nozzle 701 will blow onto the glass tableware, causing the glass tableware to cool down rapidly. This will generate compressive stress on the surface of the glass tableware and tensile stress in the inner layer, forming a uniform internal stress distribution, thereby improving the bending and impact resistance of the glass. During the cooling process, the pressure block 708 can fix the glass tableware, thereby preventing the glass tableware from being blown away by the high-speed airflow and reducing the risk of the glass tableware colliding with each other.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
