[0016] This application relates to a linear forming apparatus for glass spheres, such as... Figures 1-6 As shown, the molding device includes a frame 1 that provides basic support. A hopper 2 for receiving high-temperature glass bulbs is vertically arranged on the top of the frame 1. A molding component 3 with a symmetrical roller rotating structure is horizontally arranged in the middle of the frame 1 to achieve rolling molding and surface cleaning of the glass bulbs.

The discharge hopper 4 is inclined with an inclination angle of 150-160° relative to the horizontal plane. A collection hopper 5 for collecting debris is arranged directly below the molding component 3.

[0017] The forming assembly 3 comprises a motor 6, a frame plate 7, a shaft 8, a roller 9 and a brush 10, the frame plate 7 is vertically fixedly arranged at one end of the upper portion of the rack 1 and serves as the main support structure of the forming assembly 3, two shafts 8 are symmetrically arranged on one side of the frame plate 7, one end of each of the two shafts 8 is connected with the frame plate 7 through a bearing seat to ensure that the shaft 8 can stably and smoothly rotate, the outer portion of the shaft 8 is sleeved with the roller 9 having a hollow structure, the roller 9 and the shaft 8 are connected through a key to realize synchronous rotation of the two, the surface of the roller 9 is uniformly formed with screw grooves 11, the screw grooves 11 are not only used for linear conveying of the glass balls but also used for extrusion forming operation of the glass balls during the conveying process, when the high-temperature ball blank falls between the rollers 9, the ball blank is gradually formed into a smooth glass ball under the action of the screw grooves 11 with the rotation of the roller 9, the brushes 10 are arranged at the end portion of the shaft 8 and adjacent to the roller 9, the brushes 10 are in a rotating mode and are used for cleaning the surface of the formed glass ball to remove the slag and impurities attached to the surface, the cleaned glass ball smoothly slides to the upper portion of the discharge hopper 4 under the action of its own gravity and is ready for the next process, in order to drive the two shafts 8 to rotate synchronously, the motor 6 is arranged in the rack 1, the motor 6 is connected with the shaft 8 through a belt transmission mode to realize power transmission, when the motor 6 is started, the belt is rotated to drive the two shafts 8 to rotate synchronously, so that the roller 9 and the brush 10 can also work synchronously.

[0018] The high-temperature ball blank falls into the rollers 9 through the feeding hopper 2, the motor 6 is started to drive the shaft 8 to rotate through a belt transmission, and then drives the roller 9 and the brush 10 to rotate, the screw grooves 11 on the surface of the roller 9 perform linear conveying and extrusion forming operation on the ball blank to form a smooth glass ball, the brush 10 cleans the surface of the formed glass ball to remove the slag and impurities, the cleaned glass ball slides to the upper portion of the discharge hopper 4 under the action of its own gravity and is ready for the next process, the slag generated in the forming process is collected in the collecting hopper 5 to keep the working environment clean, the linear forming device for the glass ball in the embodiment realizes integrated operation of linear conveying, extrusion forming and surface cleaning of the glass ball through the cooperation of the motor 6 driving, the belt transmission mode and the roller 9 and the brush 10, the shaft 8 adopts unilateral support mode and is combined with the hollow structure of the roller 9 to effectively reduce the self weight of the roller 9 and then meet the stable operation, the device has compact structure, stable operation and convenient maintenance and effectively improves the production efficiency and quality of the glass ball.

[0019] In use, the high-temperature glass ball preform is fed into the device through the hopper 2. The preform falls into the threaded groove 11 between the rollers 9. The speed of the motor 6 is adjusted to control the rotation speed of the rollers 9, thereby adjusting the forming speed and surface smoothness of the glass ball. The forming process of the glass ball in the rollers 9 is observed to ensure that the preform is evenly pressed to form a regular spherical shape. After forming, the glass ball is cleaned by the brush 10 to remove the debris and impurities attached to the surface, and then slides into the discharge hopper 4. The wear of the rollers 9 and brush 10 is checked regularly, and severely worn parts are replaced in time. The debris in the hopper 5 is cleaned to keep the working environment clean. The motor 6 and the transmission belt are regularly maintained to ensure long-term stable operation. Example

[0020] Based on Example 1, such as Figures 7-8 As shown, in actual production, we found that the roller 9 in Example 1, being a solid structure, absorbs a large amount of heat from the high-temperature glass bulb after running for a period of time and cannot dissipate it in time. To reduce the temperature of the roller 9, it is usually necessary to stop the machine for cooling. To accelerate the cooling rate, operators often spray cooling water on the surface of the roller 9. However, the cooling water is usually tap water or neutral water, which contains a lot of mineral impurities. When this cooling water comes into contact with the high-temperature roller 9, the water evaporates quickly, while the mineral impurities adhere to the surface of the roller 9 and are difficult to remove. Over time, these attached mineral impurities will cause irregular spherical pits to form on the glass bulbs during the forming process, seriously affecting the quality of the finished glass bulbs.

[0021] To address this issue, this embodiment improves the structure of roller 9 by replacing it with a helical spring 12. Spring 12 consists of a working part 13 and a connecting part 14. The connecting part 14 is symmetrically arranged at both ends of the working part 13 and is fixedly connected to the shaft 8, ensuring that spring 12 can be stably mounted on the shaft 8. The working part 13 is sleeved and spaced apart from the shaft 8. This design creates a gap between spring 12 and shaft 8, facilitating airflow and heat dissipation. The helical spring 12 structure increases the heat dissipation area, allowing air to fully contact the surface of spring 12 and carry away more heat, thereby reducing the temperature rise of roller 9 and decreasing the frequency of shutdowns for heat dissipation. Since forced cooling water is not required, mineral impurities are prevented from adhering to the surface of roller 9, effectively preventing the formation of spherical pits and improving the finished quality of glass beads. The elasticity of spring 12 allows it to deform under external force, adapting to the production of glass beads of different specifications and requirements, thus improving the versatility of the device.

[0022] When the device is running, the spiral spring 12 will rotate with the rotation of the shaft 8, due to the interval arrangement between the working part 13 of the spring 12 and the shaft 8, the flowing air can pass through the gap and fully contact with the surface of the spring 12, thereby taking away the heat absorbed by it, this natural cooling method not only has high efficiency, but also does not need additional cooling equipment or cooling water, greatly simplifying the production process, in addition, due to the spiral structure of the spring 12, its surface area is relatively large, which further improves the heat dissipation effect, at the same time, the elasticity of the spring 12 enables it to deform to a certain extent when subjected to external force, thereby adapting to the production of glass balls of different specifications and requirements.

[0023] In use, the spiral structure of the spring 12 greatly increases its surface area, enabling air to more fully contact the surface of the spring 12, effectively taking away the heat generated during operation, the interval arrangement between the spring 12 and the shaft 8 forms an air flow channel, promoting the flow of air and further improving the heat dissipation efficiency, this natural cooling method does not need additional cooling equipment or cooling water, reducing energy consumption and production cost, by adopting the natural cooling method, there is no need to spray cooling water, thus completely avoiding the attachment of mineral impurities on the surface of the roller 9 (now the spring 12), avoiding the formation of spherical pits due to the attachment of mineral impurities, significantly improving the finished product quality and surface finish of the glass balls, the good heat dissipation performance of the spring 12 reduces the frequency of shutdown for heat dissipation due to excessive temperature, improving the continuous operation time of the production line, the elastic design of the spring 12 enables it to adapt to the production of glass balls of different specifications and requirements, enhancing the versatility and stability of the device, the spring 12 structure is relatively simple, easy to disassemble and replace, reducing maintenance difficulty and cost, without the need to regularly clean the cooling water system and deal with the problem of mineral impurity attachment, simplifying the maintenance process of the production line, the spring 12 material has good elasticity and wear resistance, and can withstand pressure and friction for a long time during operation, avoiding the problem of material thermal fatigue and deformation caused by heat accumulation inside the solid roller 9, prolonging the service life of the equipment.
