Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0023] See also Figure 1-5The present invention provides a technical solution: a cooling mechanism for glass melting and forming, comprising a conveyor belt 1 and a cooling plate 2, a support frame 4 is arranged in the middle of the conveyor belt 1, the top of the support frame 4 is a bending structure, a hydraulic cylinder 6 is fixed to the top inner wall of the support frame 4 by bolts, a connecting plate 7 is fixed to the output end of the hydraulic cylinder 6, the cooling plate 2 is connected and installed at the bottom of the connecting plate 7, and a size sensor 3 and a control system 5 are respectively installed on the side and top of the support frame 4, and the model of the size sensor 3 is Keyence LK-G5000, the control system 5 mainly includes a processor, a drive module, a communication module, a power module, and a temperature monitoring module. The processor is responsible for receiving and processing the signal of the size sensor 3 and calculating the height of the cooling plate 2. The size sensor 3 is used to sense the thickness of the glass product and transmit the signal to the control system 5 through wireless communication. The cooling plate 2 is provided with a plurality of special-shaped cooling channels for cooling water to flow. The size sensor 3 of this structure senses the thickness of the glass product on the conveyor belt 1 and transmits the signal to the control system 5 through wireless communication. After receiving the signal, the control system 5 calculates the required height of the cooling plate 2 and controls the extension and contraction of the hydraulic cylinder 6 through the drive module. The output end of the hydraulic cylinder 6 drives the connecting plate 7 to move up and down, thereby adjusting the height of the cooling plate 2 so that it maintains an optimal contact distance with the surface of the glass product. At the same time, the cooling plate 2 is provided with a plurality of special-shaped cooling channels for cooling water to flow. These channels can ensure that the cooling water is evenly distributed inside the cooling plate 2, avoiding the local overcooling or overheating caused by the uneven distribution of the cooling medium in the traditional cooling plate, ensuring the uniformity and stability of the cooling process, thereby solving the problems in the prior art that the distance between the cooling plate 2 and the glass contact surface cannot be adjusted and the cooling medium is unevenly distributed. The problem of poor cooling effect caused by uneven distribution of quality is solved, which is beneficial to improving the cooling quality and production efficiency of glass products. A cooler 9 is installed at the bottom of the conveyor belt 1 through a bracket, and a circulating pump 10 is installed on one side of the outside of the cooler 9. The two ends of the cooling plate 2 are respectively provided with a liquid inlet pipe and a liquid outlet pipe, and the two ends of the cooler 9 and the liquid inlet pipe and the liquid outlet pipe of the cooling plate 2 are connected with a circulating hose 11. The circulating pump 10 of this structure transports the cooling water in the cooler 9 to the liquid inlet pipe of the cooling plate 2 through the circulating hose 11, and the cooling water flows evenly in the multiple special-shaped cooling channels inside the cooling plate 2 to absorb the heat of the glass products. Finally, it returns to the cooler 9 for cooling through the liquid outlet pipe of the cooling plate 2 and the circulation hose 11. The whole circulation process ensures the continuous supply of cooling water and the stability of the temperature, and improves the uniformity and stability of the cooling effect. The special-shaped cooling channel inside the cooling plate 2 includes an arc-shaped curved channel 22 and a straight-line variable-diameter channel 23, and there are two arc-shaped curved channels 22 and two straight-line variable-diameter channels 23 respectively. The arc-shaped curved channels 22 and the straight-line variable-diameter channels 23 of this structure can form a uniform flow path for the cooling water inside the cooling plate 2, covering a larger cooling area, ensuring the uniform distribution of the cooling water inside the cooling plate 2 and efficient heat exchange.A liquid inlet converging chamber 21 is provided inside the side of the cooling plate 2 close to the liquid inlet pipe, and a liquid outlet converging chamber 24 is provided inside the side of the cooling plate 2 close to the liquid outlet pipe. The liquid inlet converging chamber 21, the arc-shaped curved channel 22, the straight variable diameter channel 23 and the liquid outlet converging chamber 24 are all interconnected. After the cooling water enters the liquid inlet converging chamber 21, it is quickly and evenly distributed to the entrances of the four cooling channels, and finally the cooling water is collected through the liquid outlet converging chamber 24 and flows out from the liquid outlet pipe of the cooling plate 2. Elastic contact pads 25 are bonded and fixed to the edges on both sides of the bottom of the cooling plate 2, and the elastic contact pads 25 are of a strip-shaped structure. The elastic contact pads 25 of this structure descend when the cooling plate 2 is in contact with the glass product. When in contact, it can gently fit on the glass surface, provide uniform contact pressure, avoid scratching or other damage to the glass surface, and ensure good heat transfer effect. Guide columns 8 are welded and fixed on both sides of the top of the connecting plate 7, and the upper end of the support frame 4 is symmetrically provided with guide holes that match the guide column 8 structure. The guide column 8 of this structure cooperates with the guide hole on the support frame 4 to ensure the stability and linearity of the connecting plate 7 when it moves up and down under the drive of the hydraulic cylinder 6, avoid the position deviation of the cooling plate 2 caused by deflection or shaking, and ensure that the cooling plate 2 can be accurately and smoothly adjusted to the required height to maintain the best contact distance with the surface of the glass product. The inner wall of the guide hole of the support frame 4 is symmetrically provided with a limit block 12, and the outer walls on both sides of the guide column 8 are provided with a movable groove 13 that matches the limit block 12 structure. This structure ensures the stability and linearity of the guide column 8 when it moves up and down in the guide hole through the cooperation of the limit block 12 and the movable groove 13, and prevents the guide column 8 from deflecting or shaking during the movement. Fastening bolts 14 are inserted through the threaded structure on both sides of the connecting plate 7, and threaded holes that match the fastening bolts 14 structure are symmetrically provided on the top of the cooling plate 2, and hidden handles are provided on both sides of the top of the cooling plate 2. This structure firmly fixes the cooling plate 2 through the fastening bolts 14 On the connecting plate 7, it is ensured that the cooling plate 2 will not loosen or fall off during the up and down movement, and the design of the hidden handle on the cooling plate 2 facilitates the installation and removal of the cooling plate 2, making maintenance and replacement more convenient, while not affecting the appearance and use effect of the cooling plate 2. A number of strip-shaped inserts 15 are evenly arranged in the middle of the bottom of the connecting plate 7, and a number of strip-shaped grooves 16 that are compatible with the strip-shaped inserts 15 are arranged in the middle of the top of the cooling plate 2. This structural connecting plate 7 ensures the precise alignment and firm connection of the cooling plate 2 during installation through the cooperation of the strip-shaped inserts 15 and the strip-shaped grooves 16, preventing the cooling plate 2 from deflecting or shaking during the up and down movement.
[0024] Working principle: When using the cooling mechanism for glass melting and forming, first, the size sensor 3 senses the thickness of the glass product on the conveyor belt 1, and transmits the signal to the control system 5 through wireless communication. After receiving the signal, the processor of the control system 5 calculates the required height of the cooling plate 2, and controls the extension and contraction of the hydraulic cylinder 6 through the drive module. The output end of the hydraulic cylinder 6 drives the connecting plate 7 to move up and down, and the guide column 8 will slide in the guide hole of the support frame 4. At the same time, the limit block 12 cooperates with the movable groove 13 on the guide column 8, and the elastic contact pad 25 at the bottom of the cooling plate 2 is in the cooling state. When the cooling plate 2 descends, it gently fits the surface of the glass product. The cooler 9 transports cooling water to the liquid inlet pipe of the cooling plate 2 through the circulating pump 10. The cooling water enters the liquid inlet convergence chamber 21 inside the cooling plate 2, and then is evenly distributed to the arc-shaped curved channel 22 and the straight variable diameter channel 23. The cooling water flows in these channels, absorbs the heat of the glass product, and then is collected through the liquid outlet convergence chamber 24 and flows out from the liquid outlet pipe of the cooling plate 2, and finally returns to the cooler 9 through the circulating hose 11 for cooling. The whole process ensures the continuous supply of cooling water and the stability of temperature, thereby completing a series of tasks.
