Description

Technical Field

[0001] This utility model relates to the technical field of glass processing, specifically to a molten glass shearing and guiding device. Background Technology

[0002] The production of glass bottles typically involves the forming process of high-temperature molten glass, which requires strict temperature and flow control. Traditional flow guiding devices play a crucial role in this process, their main function being to guide the molten glass from the furnace to various forming equipment to ensure a stable and uniform glass flow, thereby guaranteeing the continuity of the production line and the quality of the glass bottles.

[0003] Currently, most flow guiding devices used in glass bottle production have several problems. The most widely used flow guiding devices in glass bottle production are traditional metal flow guiding pipe systems, which mainly rely on gravity and physical guidance to transport molten glass. However, existing flow guiding systems have several shortcomings and cannot effectively meet the production line's requirements for high efficiency, stability, low energy consumption, and high-quality glass bottles. The most significant problem is the lack of effective insulation. Because molten glass easily solidifies rapidly upon cooling at high temperatures, the flow guiding device cannot maintain the optimal flow state of the molten glass during operation. The fluidity of glass decreases significantly at excessively low temperatures, which may lead to unstable bottle forming quality and even equipment failure. Furthermore, the flow guiding device itself is constantly exposed to high-temperature environments without insulation, resulting in increased energy waste and equipment wear and tear.

[0004] In addition, the fluid flow in the guide pipe may be uneven, resulting in uneven heat distribution and poor material transfer. Existing guide devices often lack effective design guarantees, which prevents the glass liquid from being homogenized during the guide process, thus affecting the forming effect and quality of the glass bottle. Utility Model Content

[0005] To address the aforementioned shortcomings, this utility model provides the following technical solution:

[0006] A molten glass shearing and guiding device includes a glass melting chamber with a discharge port at the bottom. A mounting block is located at one bottom side of the glass melting chamber, and a fixing block is mounted on the mounting block. Shearing blades are symmetrically arranged on both sides below the discharge port, each shearing blade connected to a shearing arm. Each shearing arm has a vertically oriented rotating shaft at its tail end, and a rotating gear meshing at the bottom end of each rotating shaft. The bottom end of the rotating shaft is located at the bottom end of the fixing block. A feed hopper is located below the shearing blades, opposite the discharge port, and a guide pipe is located at the bottom of the feed hopper, with helical rifling inside the guide pipe.

[0007] Furthermore, the bottom end of the fixing block is provided with two symmetrical rotating shaft seats, and the tail end of the rotating shaft is disposed inside the rotating shaft seats.

[0008] Furthermore, the cutting blades on both sides are semi-circular and staggered, and the bottom of the cutting blade has a trapezoidal support structure.

[0018] Combination Figures 1 to 2 Shown:

[0019] A molten glass shearing and guiding device includes a glass melting chamber 1, a discharge port at the bottom of the glass melting chamber 1, an installation block 3 at one bottom side of the glass melting chamber 1, a fixing block 4 on the installation block 3, symmetrically arranged shearing blades 5 on both sides below the discharge port 2, each shearing blade 5 being connected to a shearing arm 6, each shearing arm 6 having a vertically oriented rotating shaft 7 at its tail end, each rotating shaft 7 having a rotating gear 8 meshing at its bottom end, the bottom end of the rotating shaft 7 being located at the bottom end of the fixing block 4, a feed hopper 9 being located below the shearing blades and opposite the discharge port 2, a guide pipe 10 being located at the bottom of the feed hopper, the guide pipe 10 having helical rifling inside, which can effectively ensure the uniformity of the molten glass during sliding.

[0020] The bottom of the fixed block 4 is provided with two symmetrical rotating shaft seats 7. The tail end of the rotating shaft 7 is set in the rotating shaft seat 7, and the rotating shaft 7 rotates through the rotating shaft seat.

[0021] The blades of the two shearing blades 5 are semi-circular and staggered, and the bottom of the shearing blades 5 has a trapezoidal support structure. The staggered design facilitates the adjustment of the shearing angle.

[0022] The guide pipe 10 includes an upper pipe and a lower pipe. The upper pipe has a hollow inner wall and oil guide pipes at both the upper and lower ends, which are connected to high-temperature hot oil for insulation.

[0023] The glass melting furnace 1 has supports 11 on both sides, and mounting plates 12 are connected to the bottom of the supports 11. The guide pipe 10 passes through the mounting plate 12 and is fixed.

[0024] The shearing arm 6 is equipped with a nozzle, and the bottom of the nozzle is equipped with a conduit. The nozzle faces the blade of the shearing blade 5 and is used to spray water to cool the shearing blade 5.

[0025] A cantilever 13 perpendicular to the shearing arm 6 is provided outward from the middle of the rotating shaft 7. A round shaft 14 is provided on the cantilever 13, and a collar 15 is provided on the round shaft 14. The collar 15 is connected to a hydraulic telescopic rod. The hydraulic telescopic rod is provided on the two side supports 11. The position of the hydraulic telescopic rod is set according to actual needs. The shearing arm 6 is swung by controlling the hydraulic telescopic rod to perform the shearing work.

[0026] Working principle: The material is melted into a liquid state in the glass melting furnace and discharged through the outlet. The extension and retraction of the hydraulic telescopic rod, together with the cantilever and the round shaft, causes the shearing arm to move in and out, driving the shearing blade to cut the flowing molten glass. After the shearing blade returns to its original position, water is sprayed from the nozzle to cool the shearing blade. The cut molten glass flows into the guide pipe and slides out under the action of the spiral rifling and the feed hopper. When it enters the upper pipe of the pipeline, the temperature is maintained by high-temperature hot oil, and finally it flows to the next process.
