Description

[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, glassware, bottles, and other light industrial glass products are typically formed using glass bottle-making machines, which 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] Modern light industrial glass production lines typically use one feeder to supply material to multiple bottle-making machines. The glass droplets are conveyed to each machine position via guide chutes. Under the influence of gravity, the glass droplets slide along the inclined guide chutes into the forming mold. During this sliding process, the glass droplets come into contact with and slide within the chutes, causing changes in their shape and temperature, and even scratches on their surface. These defects can create unavoidable surface defects in the glass products during the forming process, and in severe cases, prevent the glass from being formed at all. Utility Model Content

[0024] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0025] like Figure 1 As shown, this utility model proposes a glass droplet guiding channel device, including: a multi-segment guiding channel body 4, the guiding channel body 4 being provided with a flow channel for the glass droplet 3 to slide.

[0026] The material guide trough 4 is equipped with a ventilation structure, which is used to introduce airflow into the flow channel. The airflow is evenly distributed on the inner wall of the material guide trough 4 to form an air cushion layer, which is used to isolate the glass droplets 3 from the inner wall of the material guide trough 4.

[0027] The glass droplet guiding trough device also includes a first fixing frame 1 and a second fixing frame 2. The guiding trough body 4 includes a feeding section 41, a discharging section 42, and a guiding section 43. The first fixing frame 1 is fixedly connected to the feeding section 41, and the second fixing frame 2 is fixedly connected to the discharging section 42. The first fixing frame 1 and the second fixing frame 2 fix both ends of the guiding trough body 4 in the horizontal and vertical directions. The second fixing frame 2 is also provided with a connecting mechanism 6. The second fixing frame 2 is connected to the guiding section 43 through the connecting mechanism 6. An adjustment mechanism 5 is provided at the end of the guiding section 43 away from the second fixing frame 2. The connecting mechanism 6 can be selected according to actual needs, including but not limited to clamps and grippers. The adjustment mechanism 5 can be an adjusting bracket to facilitate the adjustment of the position of the end of the guiding section 43, so that the feeding section 41, the discharging section 42, and the guiding section 43 cooperate with each other to form a smooth sliding channel for the glass droplet 3.

[0028] The feeding section 41, discharging section 42, and guiding section 43 are all double-walled pipe structures, with the guiding section 43 located between the feeding section 41 and the discharging section 42. The structures of the feeding section 41, the discharging section 42, and the guiding section 43 are identical, but their curvatures differ. The feeding section 41 and the discharging section 42 use bent pipes, while the guiding section 43 uses a straight pipe. The tangent at the inlet of the feeding section 41 and the tangent at the outlet of the discharging section 42 are both in a vertical plane, facilitating the sliding in and out of the glass droplet 3.

[0029] Specifically, such as Figures 2-4As shown, the guide section 43 has a semi-circular cross-section and is provided with a channel 431 (the channel of the feed section 41, the channel of the discharge section 42, and the channel of the guide section 43 are joined together to form a flow channel for the glass droplets). A gas supply chamber 432 is provided between the outer and inner walls of the guide section 43. The guide section 43 is also provided with an air inlet 434 and an air outlet 435. The air inlet 434 is connected to an external gas supply system with adjustable gas temperature (not shown in the figure). The gas supply system with adjustable gas temperature is existing technology and will not be described in detail here. Gas at a preset temperature and pressure can be continuously supplied to the gas supply chamber 432 through the air inlet 434.

[0030] Furthermore, the inner wall of the guide section 43 is provided with several air holes 433 of the same diameter, and the channel 431 is connected to the air supply chamber 432 through the air holes 433. The air supply chamber 432 and the air holes 433 form a ventilation structure, and the gas in the air supply chamber 432 is delivered to the channel 431 through the air holes 433. The air flow is distributed on the inner wall of the guide section 43 to form an air cushion layer.

[0031] It should be noted that a number of vents 433 are staggered in rows on the inner wall of the guide section 43, with each row of vents 433 being equidistant. The vents 433 are inclined along the sliding direction of the glass droplet 3, so that the pressurized gas ejected from the vents 433 is evenly distributed between the glass droplet 3 and the inner wall of the guide section 43, forming a more stable air cushion layer and preventing the glass droplet 3 from contacting the inner wall of the guide section 43 and causing friction and scratches. Furthermore, the diameter of the vents 433 gradually increases along the sliding direction of the glass droplet 3, causing the airflow entering the channel 431 from the vents 433 to diffuse to both sides, facilitating a uniform distribution of airflow in the radial direction. The diameter of the vents 433 is selected according to the weight of the glass droplet 3; in this application, the diameter of the vents 433 is 0.5mm-1.0mm, to avoid excessive gas discharge from the vents 433 from adversely affecting the glass droplet 3.

[0032] Correspondingly, there are air cushion layers between the feeding section 41 and the glass droplet 3, and between the discharging section 42 and the glass droplet 3, so that the glass droplet 3 will not come into contact with the guide trough 4 when it slides in the entire flow channel, thus avoiding scratches on the glass droplet 3 and improving the surface quality of the glass droplet 3 and the forming quality of subsequent glass products.

[0033] The inventors discovered that existing glass droplet guide channels are made of graphite-lined metal to reduce the impact of the guide channel on the droplets. Some manufacturers also introduce lubricant into the channel to reduce surface defects of the droplets. However, these solutions cannot avoid deformation and temperature changes on the side of the glass droplet in contact with the guide channel. In particular, for multi-unit bottle making machines, there are significant differences in forming quality between bottle making machines at different distances from the feeder.

[0034] The air cushion layer used in this application prevents the glass droplet 3 from directly contacting the guide trough 4, avoiding deformation and temperature unevenness caused by contact between the glass droplet 3 and the guide trough 4, thus improving the quality and temperature uniformity of the glass droplet 3. Simultaneously, this invention can further improve the temperature control accuracy of the glass droplet 3 by adjusting the air supply temperature of the air cushion layer in the guide trough 4, significantly improving the feeding quality of the glass droplet 3 and enhancing the forming quality and process stability of the bottle-making machine. In some embodiments, the guide portion 43 in the guide trough 4 can be provided in multiple segments to facilitate segmented temperature control and improve the accuracy of temperature control.

[0035] In this embodiment, a gas supply system delivers gas at a preset temperature and pressure into the guide trough 4. After the gas is discharged into the flow channel, a stable air cushion layer is formed on the inner wall of the guide trough 4. The air cushion layer prevents direct contact between the glass droplet 3 and the guide trough 4, thereby avoiding frictional scratches between the glass droplet 3 and the guide trough 4. The air cushion layer also increases the thermal resistance between the glass droplet 3 and the guide trough 4, reduces the temperature difference between the contact and non-contact surfaces of the glass droplet 3, and minimizes shape changes and temperature differences between different areas of the glass droplet 3 during the sliding process.

[0036] Understandably, the inner wall of the feed trough 4 can also be coated with a high-temperature resistant graphite material to improve the lubricity of the inner wall and further reduce the scratches on the glass droplets 3.

[0037] Working principle: Gas at a preset temperature and pressure is supplied to the material guide tank 4 through the gas supply system. After the gas is discharged into the flow channel, a stable air cushion layer is formed on the inner wall of the material guide tank 4. The air cushion layer prevents the glass droplets 3 from directly contacting the material guide tank 4, thereby avoiding friction and scratches between the glass droplets 3 and the material guide tank 4.

[0038] 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.
