Description

Technical Field

[0001] This utility model relates to the field of glassware manufacturing technology, and in particular to a temperature-controlled glass material dripping tube. Background Technology

[0002] Glassware, glass bottles, and other light industrial glass products have wide applications in industrial and daily-use sectors. With the expansion of application areas, downstream markets have significantly increased their demands for the quality of glass products, such as high-end daily necessities and high-purity reagent storage containers. Depending on the shape and size of the glass products, the manufacturing process of glassware, bottles, and other light industrial glass products typically utilizes glass bottle-making machines to shape molten glass into various glass products. Common forming processes for glass bottle-making machines are pressing and blowing, which use molds of a specific shape to press or blow glass droplets into the desired shape. The forming quality of glass bottle-making machines mainly depends on the control of the shape and temperature of the glass droplets.

[0003] In modern light industrial glass production lines, a single feeder typically supplies glass to multiple bottle-making machines. Molten glass of a specific shape and weight is cut into glass droplets by a shearing device. These droplets are then transported to each bottle-making machine position via a distributor and a drop pipe. During the shearing process, the shearing device can cause the droplet's fall center to deviate from the distributor's center, affecting the forming quality and potentially causing a glass flying accident. Therefore, a drop pipe is usually installed between the shearing device and the distributor to control the droplet's fall center to be coaxial with the distributor.

[0004] However, during the process of glass droplets falling in the drop tube, they are prone to contact with the inner wall of the drop tube, which can cause changes in the shape and temperature of the glass droplets, and even cause scratches or foreign matter to adhere to the surface of the droplets. This results in unavoidable surface defects during the glass forming process, which seriously affects the forming quality and product yield of glassware and bottles. Utility Model Content

[0005] This invention provides a temperature-controlled glass dropper tube, which can solve the problem of product quality defects caused by the contact between the glass dropper and the tube wall during the dropper process, as mentioned in the background art.

[0006] A temperature-controlled glass material dripping tube includes a receiving funnel and a dripping tube body, wherein the receiving funnel and the dripping tube body are coaxially arranged and fixed to each other.

[0007] The discharge tube is provided with a flow channel, and a number of air holes connected to the flow channel are opened on the inner wall of the discharge tube. By supplying air to the air holes, an air cushion layer structure is formed on the inner wall of the discharge tube. The air cushion layer structure is used to isolate the glass droplets from the inner wall of the discharge tube.

[0008] Preferably, both the receiving funnel and the discharge pipe are sleeve structures with double-walled tubes and an air supply chamber in the middle.

[0009] Preferably, both the outer wall of the receiving funnel and the outer wall of the discharge pipe are provided with air inlets, and the air inlets are connected to the corresponding air supply chambers.

[0010] Preferably, the air supply chamber is connected to the air hole.

[0011] Preferably, the plurality of air holes are staggered in rows on the inner wall of the material discharge tube, and the plurality of air holes in each row are equidistant.

[0012] Preferably, the pores are inclined along the direction of glass droplet movement, and the diameter of the pores gradually increases along the direction of glass droplet movement.

[0013] Preferably, the pore diameter is 0.5mm-1.0mm.

[0014] Preferably, the air inlet is connected to the air supply system.

[0015] Preferably, the gas supply system is equipped with a temperature regulation module.

[0016] Preferably, the inner wall of the receiving funnel is also provided with the air holes.

[0017] The beneficial effects of this utility model are:

[0018] This temperature-controlled glass dropper pipe allows the glass droplets to fall gradually through a receiving funnel, then through the flow channel of the dropper body, and finally outwards. During the droplet's descent, the pressurized gas ejected from the vent forms an air cushion layer between the glass droplet and the dropper body, preventing direct contact between them. This avoids surface scratches and foreign matter adhesion on the glass droplets, improving the forming quality and yield of subsequent glass products. Attached Figure Description

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0028] like Figure 1 , Figure 3 As shown, this utility model proposes a temperature-controlled glass material dripping tube, including a receiving funnel 2 and a dripping tube body 3. The receiving funnel 2 and the dripping tube body 3 are coaxially arranged and fixed to each other by bonding. In some embodiments, the receiving funnel 2 and the dripping tube body 3 are manufactured using an integrated process to form a single unit.

[0029] Both the receiving funnel 2 and the discharge pipe 3 are double-walled sleeve structures with an air supply chamber 4 in the middle. Both the outer wall of the receiving funnel 2 and the outer wall of the discharge pipe 3 have air inlets 5, which are connected to the corresponding air supply chambers 4. The air inlets 5 are connected to an air supply system (not shown in the figure). The air supply system is equipped with a temperature regulation module. Air supply systems that can regulate gas temperature are existing technology and will not be described in detail here.

[0030] Specifically, such as Figures 2-4 As shown, the discharge tube 3 can be fixed in use by a fixing bracket 7, generally by insertion. The discharge tube 3 has an outlet 31 at its bottom and a longitudinal channel 32. When the glass droplet 1 falls, it first passes through the inner cavity 21 of the receiving funnel 2, gradually descends, and then flows out through the channel 32 and is discharged from the outlet 31. Several air holes 6 connected to the channel 32 are formed on the inner wall of the discharge tube 3, allowing the air chamber 4 to communicate with the air holes 6. Each air hole 6 has the same diameter. The air holes 6 are staggered in rows on the inner wall of the discharge tube 3, with each row of air holes 6 evenly spaced. Optionally, the inner wall of the receiving funnel 2 also has air holes 6.

[0031] Furthermore, such as Figures 5-6As shown, the air holes 6 in the dropper tube 3 are inclined along the direction of glass droplet 1's movement, so that the pressurized gas ejected from the air holes 6 is evenly distributed between the glass droplet 1 and the inner wall of the dropper tube 3. This not only positions the glass droplet 1 but also effectively controls its descent along the central axis of the dropper tube 3, preventing contact between the droplet and the tube wall. The diameter of the air holes 6 gradually increases along the direction of glass droplet 1's movement, causing the airflow entering the flow channel 32 from the air holes 6 to diffuse to both sides, facilitating a uniform radial distribution of the airflow. The diameter of the air holes 6 is selected based on the weight of the glass droplet 1. In this application, the diameter of the air holes 6 is 0.5mm-1.0mm to avoid excessive gas discharge from the air holes 6 from adversely affecting the glass droplet 1.

[0032] In this embodiment, a gas supply system delivers gas at a preset temperature and pressure to the air inlet 5. After the gas fills the air supply chamber 4, the system continues to supply gas, and the airflow is discharged into the flow channel 32 through the air hole 6, forming an air cushion layer structure on the inner wall of the drop tube 3. This air cushion layer structure isolates the glass droplet 1 from the inner wall of the drop tube 3. When the glass droplet 1 falls, it first passes through the funnel cavity 21 of the receiving funnel 2, gradually falls, and then passes through the flow channel 32 and is discharged outward from the outlet 31. During the fall of the glass droplet 1 in the flow channel 32, the air cushion layer structure formed between the glass droplet 1 and the drop tube 3 by the pressurized gas ejected from the air hole 6 prevents direct contact between the glass droplet 1 and the drop tube 3, thereby avoiding surface scratches and foreign matter adhesion on the glass droplet 1. Moreover, the staggered distribution of the pores 6 can make the gas distribution in the flow channel 32 more uniform, making the air cushion layer more stable and preventing the glass droplet 1 from contacting the inner wall of the drop tube 3 and causing friction and scratches.

[0033] In addition, the temperature of the gas supply can be adjusted during gas supply to further improve the temperature uniformity of the glass droplet 1, avoid excessive cooling of the glass droplet 1, and facilitate the formation of homogeneous glass droplets 1 that meet the requirements of the bottle making machine.

[0034] In some embodiments, a multi-segment material tube body 3 can be provided, with the ends of the multi-segment material tube body 3 spliced ​​together, which facilitates segmented temperature control of the glass droplet 1, thereby further improving the accuracy of temperature control.

[0035] The inventors discovered that existing drop tubes are generally made of stainless steel, with lubricant introduced into the inner wall to reduce surface defects in the droplets. However, this solution cannot prevent the glass droplets from contacting the inner wall of the drop tube, and the drop tube also causes the glass droplets to cool down, affecting the forming quality of the droplets in the bottle-making machine.

[0036] This application employs a gas-introducing method within the feeding tube, preventing direct contact between the glass droplet 1 and the inner wall of the feeding tube 3. This avoids deformation and temperature unevenness caused by contact between the glass droplet 1 and the feeding tube 3, improving the quality and temperature uniformity of the glass droplet 1. This effectively enhances the forming quality and yield of subsequent glassware and bottles. Furthermore, this invention can further improve the temperature control precision of the glass droplet 1 by controlling the temperature of the gas introduced into the feeding tube 3, significantly improving the feeding quality of the glass droplet 1 and enhancing the forming quality and process stability of the bottle-making machine.

[0037] It is understood that in some embodiments, the receiving funnel 2 and the discharge pipe 3 adopt a single-layer pipe wall structure. In this case, it is necessary to connect an air supply system to each air hole 6, which is not only cumbersome to operate, but also costly. Therefore, the sleeve structure with double-layer pipe wall and an air supply chamber 4 in the middle is the preferred structure of this application.

[0038] Working principle: When the glass droplet 1 falls, it first passes through the inner cavity 21 of the receiving funnel 2 and gradually falls down. Then it passes through the flow channel 32 and is discharged outward from the outlet 31. During the process of the glass droplet 1 falling down the flow channel 32, the pressurized gas ejected from the air hole 6 forms an air cushion layer structure between the glass droplet 1 and the drop tube 3, which can prevent the glass droplet 1 from directly contacting the drop tube 3.

[0039] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
