Support rods are provided at the four corners of the top of the main body, and a pressure plate is provided at the bottom of the support plate. This utility model uses the positive and negative threads on the outer sides of the two ends of the bidirectional threaded rod and the threaded holes inside the movable blocks to cooperate with each other, so that the two sets of movable blocks drive the clamping plates to move towards each other. The movable blocks and clamping plates are limited by the limiting rods, and the clamping plates clamp and fix the tempered glass and PVB film.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

This makes it easier for operators to remove the double-layered laminated glass and reduces the risk of hand burns. It is very convenient and quick. At the same time, the tray provides a convenient operating platform for operators. When dealing with larger double-layered laminated glass, it also provides some support for the glass, making it easier for them to transfer the glass from the I-shaped plate in the heating chamber, reducing the risk of damaging the glass or injuring the operator.

[0017] 3. By setting rollers, the bottom of the rollers fixed on both sides of the front end of the I-shaped plate is in contact with the bottom surface of the heating box. During the sliding of the I-shaped plate along the guide plate, the rollers can convert the sliding friction into rolling friction, which greatly reduces the resistance when the I-shaped plate moves.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 This embodiment provides a heat curing device, including a heating chamber 103, a heating component at the top of the heating chamber 103 for raising the internal temperature of the heating chamber 103, a sealing component rotatably connected to one side of the heating chamber 103 for sealing the opening of the heating chamber 103; a guide plate 301, which is fixedly installed on the bottom inner wall of the heating chamber 103, and an I-shaped plate 300 slidably connected above the guide plate 301, with a pushing component on the surface of the guide plate 301 to push the I-shaped plate 300 outward for easy removal and handling of double-layer laminated glass by the operator, and a fixing member on the surface of the I-shaped plate 300 for clamping the double-layer laminated glass; a tray 101, which is rotatably connected to the front bottom of the heating chamber 103 via a hinge, and a support member is provided below the heating chamber 103 for supporting the tray 101; and a support frame 100, which is fixedly installed at the bottom of the heating chamber 103.

[0029] The pushing assembly includes a strip groove 304 formed on the top surface of the guide plate 301. A lead screw 305 is rotatably connected inside the strip groove 304. A corresponding nut seat 303 is threaded onto the surface of the lead screw 305. The top of the nut seat 303 is fixedly connected to the bottom surface of the I-shaped plate 300. One end of the lead screw 305 passes through the guide plate 301 and the inner wall of the heating box 103 and extends to the back of the heating box 103. A drive motor 302 is fixedly connected to the back of the heating box 103. The output shaft of the drive motor 302 is connected to one end of the lead screw 305 through a coupling. The pushing assembly and the support plate 101 are designed... Under the rotation of the lead screw 305, the nut seat 303 will move along the lead screw 305, thereby driving the I-shaped plate 300 to slide outward on the guide plate 301, pushing the double-layer laminated glass that has been heated and cured towards the opening of the heating box 103, so that the operator can easily take out the double-layer laminated glass. It is very convenient and quick. At the same time, the tray 101 provides the operator with a convenient operating platform, making it easier for them to transfer the glass from the I-shaped plate 300 in the heating box 103. When dealing with larger double-layer laminated glass, it reduces the risk of damaging the glass or injuring the operator.

[0030] The heating assembly includes a square hole 207 at the top of the heating chamber 103, with an electric heating tube 208 installed inside the hole 207. A mounting cover 201 is fixedly connected to the top of the heating chamber 103 at a position corresponding to the square hole 207. A support plate 210 is fixedly connected to the back of the heating chamber 103, and a blower 209 is fixedly mounted on the top of the support plate 210. The output end of the blower 209 is connected to a connecting pipe 202, the other end of which passes through the surface of the mounting cover 201 and communicates with the inner cavity of the cover 201. A temperature sensor 200 is installed on one inner wall of the heating chamber 103. A mounting plate 205 is fixedly connected to the bottom of one side of the heating chamber 103, and a controller 204 is mounted on the surface of the mounting plate 205. The signal output terminal of sensor 200 is electrically connected to the signal input terminal of controller 204 via a wire. Both electric heating tube 208 and blower 209 are controlled by controller 204. A display screen 203 is fixedly installed on one side surface of heating chamber 103. The signal output terminal of controller 204 is electrically connected to the signal input terminal of display screen 203. Through the setting of the heating components, when the temperature reaches the set value, controller 204 can automatically adjust the power of electric heating tube 208 or stop heating. At the same time, it can also control the wind speed of blower 209, thereby achieving precise control of the temperature inside heating chamber 103. At the same time, it can display the temperature data detected by temperature sensor 200 in real time, so that the operator can intuitively see the temperature changes inside heating chamber 103.

[0031] The controller 204 is model TMS320F2812, and the temperature sensor 200 is model pt100.

[0032] It is worth noting that the fasteners include U-shaped sleeves 311 that are slidably connected to the lower end of the I-shaped plate 300. Both sides of the end of the I-shaped plate 300 are provided with limiting members to restrict the sliding trajectory of the U-shaped sleeves 311 and prevent them from disengaging. Connecting strips 310 are fixedly connected to both sides of one end of the U-shaped sleeves 311. One end of two sets of connecting strips 310 in the same position extends to the corresponding side. A nut 309 is fixedly connected between one end of the two sets of connecting strips 310 in the same position. The inner cavity of the nut 309... A threaded rod 308 is connected to the top of the threaded rod 308, and an abutment plate 307 is fixedly connected to the top of the abutment plate 307. A handwheel 306 is fixedly connected to the top of the abutment plate 307. A rubber strip 312 is adhered to the top of the I-shaped plate 300. By setting the fasteners, rotating the handwheel 306 causes the threaded rod 308 to pass through the corresponding side nut 309 downwards, and at the same time, it drives the abutment plate 307 to move downwards and abut against the surface of the double-layer laminated glass, thereby fixing the double-layer laminated glass and preventing the glass from shifting due to vibration or thermal expansion during heating.

[0033] Preferably, the support includes two sets of second connecting rods 403. One end of each set of second connecting rods 403 is located on both sides of the support plate 101. The other end of each set of second connecting rods 403 has a receiving groove 405. A limiting rod 406 is fixedly connected to the inner cavity of the receiving groove 405. A connecting piece 407 is rotatably connected to the surface of the limiting rod 406. A first connecting rod 401 is fixedly connected to one end of the connecting piece 407. An external thread 408 is provided on the surface of the first connecting rod 401 near the connecting piece 407. A sleeve 402 is slidably fitted on the surface of the second connecting rod 403 near the connecting piece 407. An internal thread 409 corresponding to the external thread 408 is provided in the inner cavity of one end of the sleeve 402. The ends of the first connecting rod 401 and the second connecting rod 403 that are far apart from each other are rotatably inserted into the limiting rod. The positioning post 404 and the limiting post 404 are both fixedly connected to the limiting piece 400 at one end. The two sets of limiting posts 404 located at one end of the first connecting rod 401 are fixedly connected to the corresponding side surface of the pallet 101. The two sets of limiting posts 404 located at one end of the second connecting rod 403 are fixedly connected to the corresponding side surface of the support frame 100. Through the setting of the support member, after the pallet 101 is unfolded, the pallet 101 is supported to prevent the pallet 101 from overturning due to excessive force. At the same time, the sleeve 402 located on the surface of the second connecting rod 403 is slid downward and the internal thread 409 on one side of the sleeve 402 is threaded to the surface of the external thread 408 at one end of the first connecting rod 401, thereby enhancing the strength of the connection between the first connecting rod 401 and the second connecting rod 403.

[0034] Furthermore, two sets of fixing strips 315 are fixedly connected to the bottom of both sides of the front end of the I-shaped plate 300. Rollers 316 are rotatably connected between the two sets of fixing strips 315 on the same side. The bottom of the rollers 316 contacts the bottom inner wall surface of the heating box 103. Through the setting of the rollers 316, the bottom of the rollers 316 fixed to the bottom of both sides of the front end of the I-shaped plate 300 contacts the bottom surface of the heating box 103. During the sliding process of the I-shaped plate 300 along the guide plate 301, the rollers 316 can convert the sliding friction force into rolling friction force, which greatly reduces the resistance when the I-shaped plate 300 moves. At the same time, it supports the double-layer laminated glass and plays an auxiliary role in balancing and distributing the weight after the glass is placed, thereby reducing the force on the lead screw 305.

[0035] Furthermore, the limiting component includes guide strips 314 fixedly connected to the inner wall surfaces on both sides of the U-shaped sleeve 311, and guide grooves 313 are provided at the ends of the I-shaped plate 300 and at positions corresponding to the guide strips 314. The guide strips 314 are slidably connected to the inner cavities of the guide grooves 313 at the corresponding positions. Through the setting of the limiting component, the guide strips 314 on the inner walls on both sides of the U-shaped sleeve 311 cooperate with the guide grooves 313 at the ends of the I-shaped plate 300, providing precise guidance for the left and right sliding of the U-shaped sleeve 311. At the same time, the cooperation between the guide strips 314 and the guide grooves 313 can enhance the connection stability between the U-shaped sleeve 311 and the I-shaped plate 300.

[0036] Working principle;

[0037] Place the double-layer laminated glass stably on the surface of the I-beam plate 300. Then, first slide each set of U-shaped sleeves 311 towards the edge of the glass, so that the threaded rod 308 in the nut 309 on one side of the U-shaped sleeve 311 approaches the edge of the double-layer laminated glass. Then, turn the handwheel 306 in sequence. The threaded rod 308 passes through the corresponding nut 309 downwards, and at the same time, it drives the abutment plate 307 to move downwards and abut against the surface of the double-layer laminated glass, thereby fixing the double-layer laminated glass.

[0038] After the glass is fixed, the door 102 is rotated to cover and seal the opening of the heating chamber 103, forming a relatively sealed heating space. Then, the controller 204 controls the heating components to start working according to the preset temperature parameters. The electric heating tube 208 generates heat after being powered on, and the heat is dissipated into the heating chamber 103. At the same time, the blower 209 installed on the top of the support plate 210 is started, and air is blown into the mounting cover 201 through the connecting pipe 202 connected to its output end. The hot air circulates in the channel formed by the mounting cover 201 and the connecting pipe 202, and is continuously blown into the heating chamber 103. The hot air circulates continuously in the heating chamber 103, so that the temperature inside the entire heating chamber 103 rises rapidly and evenly.

[0039] During the heating process, a temperature sensor 200 installed on the inner wall of one side of the heating chamber 103 monitors the temperature inside the chamber in real time and transmits the temperature signal to the controller 204 via a wire. The controller 204 continuously compares and analyzes the received actual temperature with the preset temperature. If the actual temperature is lower than the preset temperature, the controller 204 will automatically increase the power of the electric heating tube 208 and appropriately increase the wind speed of the blower 209 to allow more hot air to enter the heating chamber 103 and promote temperature rise. If the actual temperature is higher than the preset temperature, the controller 204 will correspondingly reduce the power of the electric heating tube 208 or stop the operation of the electric heating tube 208, and make appropriate adjustments to the working status of the blower 209, such as reducing the wind speed, so that the temperature inside the heating chamber 103 drops to a suitable range. In addition, the temperature information will be transmitted to the display screen 203 simultaneously, and the operator can intuitively view the real-time temperature inside the heating chamber 103 through the display screen 203 to keep track of the heating process.

[0040] After a certain period of heating, the double-layered laminated glass has cured and needs to be removed. First, open the door 102, then lift the tray 101 upwards so that the top surface of the tray 101 is flush with the bottom inner wall of the heating box 103. As the tray 101 is opened, the first connecting rod 401 is connected to the second connecting rod 403 through the connecting piece 407 and the limiting rod 406. As the tray 101 rotates, the relative distance between the first connecting rod 401 and the second connecting rod 403 changes, and the ends of the first connecting rod 401 and the second connecting rod 403 are aligned. Then, the sleeve 402 located on the surface of the second connecting rod 403 is slid downwards, and the internal thread 409 on one side of the sleeve 402 is threaded to the surface of the external thread 408 at one end of the first connecting rod 401, thereby enhancing the strength of the connection between the first connecting rod 401 and the second connecting rod 403.

[0041] At this time, the drive motor 302 is started. The output shaft of the drive motor 302 drives the lead screw 305 to rotate through the coupling. The lead screw 305 is threadedly connected to the nut seat 303. The nut seat 303 is fixed on the bottom surface of the I-shaped plate 300. At the same time, the rollers 316 installed on the bottom of the front two sides of the I-shaped plate 300 contact the bottom inner wall surface of the heating box 103 to support the double-layer laminated glass. Under the rotation of the lead screw 305, the nut seat 303 will move along the lead screw 305, thereby driving the I-shaped plate 300 to slide outward on the guide plate 301, pushing the double-layer laminated glass that has been heated and cured towards the opening of the heating box 103, so that the operator can easily take out the double-layer laminated glass, which is very convenient and quick.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
