Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment technology, and in particular to a glass craft heating torch. Background Technology

[0002] Traditional glass craft heating torches typically use a single flame jet method, which suffers from uneven heating and poor operational flexibility, making it difficult to meet the needs of complex glass craft processing. Therefore, a glass craft heating torch is provided. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a glass craft heating torch. It simultaneously heats the glass craft using ring-shaped distributed flame nozzles, while a turntable slowly rotates the craft, ensuring uniform heating. A temperature sensor detects the temperature of one of the flame nozzles outside the inner cylinder. When the temperature of a flame nozzle is too high, the controller activates a solenoid valve, causing the spray nozzle to cool the outer shell of the flame nozzle, thus preventing damage from high temperatures. This design offers advantages such as flexible operation and reliable safety, overcoming the deficiencies of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A glass craft heating torch includes an outer cylinder, an inner cylinder fixed inside the outer cylinder, a gas pipe provided on the top of the outer wall of the inner cylinder, flame nozzles fixed at equal intervals on the gas pipe, one end of each flame nozzle extending into the inner cylinder, a water spray pipe fixed on the outside of the inner cylinder above the gas pipe, a number of spray nozzles equal to the number of flame nozzles installed on the water spray pipe, a support mechanism installed at the bottom of the inner wall of the inner cylinder, and an anti-slip pad provided on the lower end face of the outer cylinder.

[0006] As a further embodiment of this utility model: one end of the gas pipeline extends to the outside of the outer cylinder and is connected to the gas tank.

[0007] As a further embodiment of this utility model: one end of the water spray pipe extends to the outside of the outer cylinder and is connected to a solenoid valve, and one end of the solenoid valve is connected to the water supply pipe.

[0008] As a further embodiment of this utility model: a temperature sensor is fixed to the outer wall of the inner cylinder, and a controller is fixed to the outer wall of the outer cylinder. The temperature sensor and the solenoid valve are both electrically connected to the controller. Drainage holes are provided at equal intervals at the bottom of the side wall of the outer cylinder.

[0009] As a further embodiment of this utility model: the support mechanism includes an electric push rod fixed to the bottom of the inner cylinder, a servo motor is installed at the upper end of the electric push rod, and a turntable is installed at the output end of the servo motor.

[0010] As a further improvement of this utility model, a heat insulation cover is provided on the lower end face of the turntable and on the outer cover of the servo motor.

[0011] The beneficial effects of this utility model are as follows:

[0012] The glass crafts are heated simultaneously by a ring of flame nozzles, and the turntable slowly rotates the glass crafts, thus ensuring uniform heating. A temperature sensor detects the temperature of one of the flame nozzles on the outside of the inner cylinder. When the temperature of the flame nozzle is too high, the controller controls the solenoid valve to open, so that the spray head cools the outer shell of the flame nozzle, thereby preventing the flame nozzle from being damaged by high temperature. It has the advantages of flexible operation and safety and reliability. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1, referring to Figure 1-3A glass craft heating torch includes an outer cylinder 1, an inner cylinder 2 fixed inside the outer cylinder 1, a gas pipe 4 provided on the top of the outer wall of the inner cylinder 2, flame nozzles 5 fixed at equal intervals on the gas pipe 4, one end of the flame nozzles 5 extending into the interior of the inner cylinder 2, a water spray pipe 3 fixed on the outside of the inner cylinder 2 and above the gas pipe 4, and spray nozzles 15 of the same number as the flame nozzles 5 installed at equal intervals on the water spray pipe 3, a support mechanism installed at the bottom of the inner wall of the inner cylinder 2, and an anti-slip pad 12 provided on the lower end face of the outer cylinder 1.

[0019] One end of the gas pipeline 4 extends to the outside of the outer cylinder 1 and is connected to the gas tank. One end of the water spray pipe 3 extends to the outside of the outer cylinder 1 and is connected to a solenoid valve 13. One end of the solenoid valve 13 is connected to the water supply pipeline.

[0020] A temperature sensor 11 is fixed to the outer wall of the inner cylinder 2, and a controller 6 is fixed to the outer wall of the outer cylinder 1. The temperature sensor 11 and the solenoid valve 13 are electrically connected to the controller 6. Drainage holes 7 are opened at equal intervals at the bottom of the side wall of the outer cylinder 1.

[0021] The glass crafts are heated simultaneously by the ring-shaped flame nozzles 5 at the top of the inner cylinder 2, thus ensuring the uniformity of heating. The temperature of one of the flame nozzles 5 is detected by the temperature sensor 11 on the outside of the inner cylinder 2 and the temperature information is transmitted to the controller 6. When the temperature of the flame nozzle 5 is high, the controller 6 controls the solenoid valve 13 to open, so that the spray head 15 cools the outer shell of the flame nozzle 5, thereby preventing the flame nozzle 5 from being damaged due to high temperature.

[0022] Example 2 is an optimization based on Example 1, specifically:

[0023] The support mechanism includes an electric push rod 8 fixed to the bottom of the inner cylinder 2. A servo motor 9 is installed at the upper end of the electric push rod 8. A turntable 10 is installed at the output end of the servo motor 9. A heat insulation cover 14 is provided on the lower end face of the turntable 10 and outside the servo motor 9.

[0024] The glass craft is placed on the turntable 10. By controlling the extension and retraction of the electric push rod 8, the height of the turntable 10 can be adjusted to ensure that the flame emitted by the flame nozzle 5 contacts the glass craft. The turntable 10 is driven to rotate slowly by the servo motor 9, which can drive the glass craft to rotate slowly and evenly, thereby further ensuring that the glass craft is heated evenly.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
