Description

Technical Field

[0001] The utility model relates to the technical field of pre-presses, in particular to a pre-press for curved laminated glass. Background Technique

[0002] Laminated glass is a composite glass product made of two or more pieces of glass with one or more layers of organic polymer interlayers in between, and is manufactured through special high-temperature pre-pressing (or vacuum pumping) and high-temperature and high-pressure processes. Curved laminated glass is one of them, and pre-pressing work is required during the production process.

[0003] For example, Chinese Patent CN215243539U, which belongs to the technical field of pre-presses, discloses a pre-press for curved laminated glass, including a mounting frame. A pre-pressing assembly is arranged inside the mounting frame. The pre-pressing assembly includes a track motor, a hydraulic cylinder, a connecting frame and a pressing roller. The first heating assembly includes a hot air blower, an air duct and an air outlet. A second heating assembly is arranged inside the base. The track motor drives the hydraulic cylinder to move on the slide rail, so that the connecting frame and the pressing roller move. At the same time, the hydraulic cylinder drives the pressing roller to press down, thereby pre-pressing the curved laminated glass. The hot air blower generates heat, and the heat is transmitted to the inside of the mounting frame through the air duct and the air outlet, thereby performing a preliminary heating treatment on the curved laminated glass to improve the pressing effect of the curved laminated glass. The heating tube generates heat, and at the same time, the fan rotates to dissipate the heat generated by the heating tube through the heat dissipation holes, thereby heating the bottom of the curved laminated glass, so that the curved laminated glass can be uniformly heated.

[0004] The above patent still has certain defects. The patent heats the bottom of the curved laminated glass so that the curved laminated glass can be uniformly heated. After the curved laminated glass is heated and processed, its temperature does not drop completely, resulting in it being relatively soft and extremely easy to deform when subjected to external forces. The natural air cooling rate is relatively low, resulting in an increased probability of damage. Content of the Utility Model

An accelerating mechanism for releasing the heat inside the condensed water is arranged on the right side of the water storage tank;

[0007] The cooling mechanism includes a water delivery pipe connected to the front of the water storage tank. An electromagnetic valve is fixed on the outer side of the water delivery pipe.

On the left and right side walls of the inner cavity of the arc-shaped seat, a connecting block is fixed respectively. On the opposite sides of the left and right connecting blocks, a first blower is fixed respectively.

[0008] Furthermore, the end of the water delivery pipe away from the water storage tank is connected to the front of the right transfer tank. A first connection hole for the water delivery pipe to pass through is opened on the front of the arc-shaped seat, and the water delivery pipe is slidably connected to the inside of the arc-shaped seat through the first connection hole.

[0009] Furthermore, a second connection hole for the water extraction pipe to pass through is opened on the back of the arc-shaped seat, and the water extraction pipe is slidably connected to the inside of the arc-shaped seat through the second connection hole.

[0010] Furthermore, air inlet holes are opened on both the left and right sides of the arc-shaped seat and are located below the connecting blocks. A first dust-proof net is fixed inside the air inlet holes.

A linear module 1 for movement is provided on the top wall of the inner cavity of the mounting frame 3. A pre-pressing device 2 for processing curved laminated glass is provided on the lower surface of the linear module 1. The pre-pressing device 2 is a common pre-pressing machine for processing curved laminated glass on the market. An arc-shaped seat 4 is fixed on the bottom wall of the inner cavity of the mounting frame 3. A water storage tank 6 is fixed on the right side of the mounting frame 3. A threaded groove is provided on the upper surface of the water storage tank 6, and a seal is threadedly connected inside the threaded groove. A cooling mechanism 5 for accelerating the cooling and solidification of the curved laminated glass is provided on the front of the water storage tank 6. An accelerating mechanism 7 for releasing the internal heat of the condensed water is provided on the right side of the water storage tank 6. The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly known power connection technology is not described in the text. Connect the industrial power interface to power on the device, and the PLC system controls the entire device to operate as expected.

[0024] Please refer to Figures 2-3 , In order to accelerate the cooling efficiency of the processed glass, the cooling mechanism 5 in this embodiment includes a water delivery pipe 502 connected to the front of the water storage tank 6. A solenoid valve 501 is fixed on the outer side of the water delivery pipe 502. Both the left and right side walls of the inner cavity of the arc-shaped seat 4 are fixed with transfer boxes 505. A number of not less than two spiral pipes 504 are connected to the opposite sides of the two transfer boxes 505. By extending the flow path of the condensed water through the spiral pipes 504, the flow time is increased, so that the condensed water can fully absorb heat and reduce the temperature of the inner space of the arc-shaped seat 4. A connecting pipe 503 is connected between the opposite sides of the left and right spiral pipes 504. A water pump 508 is fixed on the back of the water storage tank 6. A return pipe 509 connected to the back of the water storage tank 6 is fixed on the right side of the water pump 508. A water suction pipe 507 connected to the back of the left transfer box 505 is fixed on the left side of the water pump 508. Two heating pipes 506 are fixed on the opposite sides of the two transfer boxes 505. Connecting blocks 511 are fixed on the left and right side walls of the inner cavity of the arc-shaped seat 4. First blowers 510 are fixed on the opposite sides of the left and right connecting blocks 511. The first blowers 510 are located below the transfer boxes 505.

[0025] One end of the water delivery pipe 502 far from the water storage tank 6 communicates with the front of the right transfer tank 505. A first connection hole for the water delivery pipe 502 to pass through is provided on the front of the arc-shaped seat 4. The upper surface of the arc-shaped seat 4 is provided with no less than two through holes, and the water delivery pipe 502 is slidably connected to the inside of the arc-shaped seat 4 through the first connection hole. A second connection hole for the water extraction pipe 507 to pass through is provided on the back of the arc-shaped seat 4, and the water extraction pipe 507 is slidably connected to the inside of the arc-shaped seat 4 through the second connection hole. Air inlet holes are provided on both the left and right sides of the arc-shaped seat 4 below the connection block 511. A first dust-proof net is fixed inside the air inlet holes. Through the air inlet holes, the first fan 510 can extract external air, and the first dust-proof net prevents external dust from entering the inside of the arc-shaped seat 4.

[0026] It can be seen that the cooling mechanism 5 ensures the processing work on the bottom of the curved laminated glass through the setting of the heating pipe 506 so that it is evenly heated. At the same time, through the cooperation of the spiral pipe 504 and the connecting pipe 503, the air inside the arc-shaped seat 4 is cooled when the processing is completed, so that it is in a lower temperature state, thereby cooperating with the first fan 510 to accelerate the cooling and solidification rate of the curved laminated glass.

[0027] Please refer to Figure 4 In order to further improve the cooling rate, the acceleration mechanism 7 in this embodiment includes a connection box 701 fixed to the right side of the water storage tank 6. A second fan 702 is fixed to the right side wall of the inner cavity of the connection box 701. Second dust-proof nets 703 are fixed to both the front and back of the connection box 701. A semiconductor radiator 705 located inside the connection box 701 is fixed to the right side of the water storage tank 6. Heat dissipation fins 704 are fixed to both the left and right sides of the semiconductor radiator 705. The control mode of this application is controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art, and this utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of this utility model will not be explained in detail.

[0028] Ventilation holes are provided on both the front and back of the heat dissipation fins 704. The second dust-proof net 703 is fixed inside the ventilation holes. A heat dissipation hole for inserting the left heat dissipation fin 704 is provided on the right side of the water storage tank 6, and the heat dissipation fin 704 is slidably connected to the inside of the water storage tank 6 through the heat dissipation hole. A sealing ring that fits on the outside of the left heat dissipation fin 704 is fixed inside the water storage tank 6.

[0029] Therefore, the acceleration mechanism 7 absorbs and releases the heat absorbed by the condensate water inside the arc-shaped seat 4 through the cooperation of the connection box 701, the second fan 702, the second dust-proof net 703, the heat dissipation fins 704 and the semiconductor radiator 705, avoiding the problem that the temperature of the condensate water rises due to excessive heat accumulation in the condensate water, resulting in the inability to absorb the heat inside the arc-shaped seat 4 to lower the air temperature, and further leading to the reduction of the cooling rate of the glass again.

[0030] The working principle of the above embodiment is as follows:

[0031] (1) When it is necessary to heat the bottom of the curved arc-shaped laminated glass, start the first fan 510 and the heating tube 506. The first fan 510 cooperates with the heating tube 506 and the through holes on the upper surface of the arc-shaped seat 4 to heat the bottom of the glass. When it is necessary to cool and solidify it, turn off the heating tube 506, start the water pump 508 and open the solenoid valve 501. The condensate water flows into the internal part of the right transfer box 505 through the water delivery pipe 502, and flows to the internal part of the right spiral tube 504 through the right transfer box 505. The condensate water in the right spiral tube 504 flows into the internal part of the left spiral tube 504 through the connecting pipe 503, and flows into the internal part of the left transfer box 505. The water pump 508 pumps out the condensate water through the water suction pipe 507 and transports it back to the water storage tank 6 through the return pipe 509. When the condensate water flows through the spiral tube 504 and the connecting pipe 503, it affects the surrounding air and completes heat exchange with the surrounding air, absorbing the heat in the air to lower the temperature. The first fan 510 blows the air with a lower temperature towards the curved arc-shaped laminated glass to accelerate its cooling and solidification under the action of low temperature. The cooling mechanism 5 ensures the processing work on the bottom of the curved arc-shaped laminated glass through the setting of the heating tube 506 to make it uniformly heated. At the same time, through the cooperation of the spiral tube 504 and the connecting pipe 503, the air inside the arc-shaped seat 4 is cooled when the processing is completed, making it in a lower temperature state, so as to cooperate with the first fan 510 to accelerate the cooling and solidification rate of the curved arc-shaped laminated glass.

[0032] (2) When the pre-pressing device 2 is started, start the second fan 702 and the semiconductor radiator 705 at the same time. The semiconductor radiator 705 absorbs the heat inside the water storage tank 6 through the heat dissipation fins 704 on the left side, reducing the temperature of the condensate water inside the water storage tank 6. At the same time, the second fan 702 blows air to cool the heat dissipation fins 704 on the right side, accelerating the release of heat, so as to improve the rate of heat absorption of the heat dissipation fins 704 on the left side, enabling the heat absorbed by the condensate water when flowing through the arc-shaped seat 4 to be quickly absorbed and released to the outside. The acceleration mechanism 7 absorbs and releases the heat absorbed by the condensate water inside the arc-shaped seat 4 through the cooperation of the connection box 701, the second fan 702, the second dust-proof net 703, the heat dissipation fins 704 and the semiconductor radiator 705, avoiding the problem that the temperature of the condensate water rises due to excessive heat accumulation in the condensate water, resulting in the inability to absorb the heat inside the arc-shaped seat 4 to lower the air temperature, and further leading to the reduction of the cooling rate of the glass again.
