Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a hot pressing device for processing laminated glass. Background Technology

[0002] Laminated glass is a composite glass product consisting of two or more pieces of glass with one or more layers of interlayer film between them. After special high-temperature pre-pressing or vacuum hot pressing, and then high-temperature and high-pressure processing, the glass and interlayer film are permanently bonded together. Because laminated glass is resistant to pressure but not to tension, it is often placed vertically on a platform by a crane to separate the laminated glass pieces one by one, and then heated to melt the interlayer film by heat radiation.

[0003] A search revealed Chinese patent CN220973595U, which discloses a vacuum hot pressing device for laminated glass. This patent uses a lead screw and slider sliding structure to automatically open or close the heating chamber by simultaneously moving the glass to be processed into or out of the chamber. However, placing the semi-finished glass directly upright on the placement plate, with the glass resting against the partition in the middle, may cause the finished glass to tip over during entry or exit. To better protect the glass during processing and enhance core technological competitiveness, this application proposes a new implementation scheme for a vacuum hot pressing device for laminated glass, distinct from existing technologies. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the lack of a support structure for placing glass, and to propose a hot pressing device for processing laminated glass.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hot pressing device for laminated glass processing includes a heating box, a placement plate inside the heating box, a support plate fixedly connected to the top of the placement plate, slots on both sides of the support plate, U-shaped support plates inserted into the slots, mounting openings on both sides and the top of the heating box, multiple heating wires fixedly connected to the mounting openings, side plates fixedly connected to the outside of the mounting openings, hydraulic cylinders fixedly mounted on the side plates on both sides of the heating box, and a pressing plate fixed to one end of the piston rod of the hydraulic cylinder passing through the side plate.

[0007] Furthermore, one end of the heating box is connected to a sealed door via a hinge, a handle is fixedly connected to one side of the outer wall of the sealed door, and an observation window is embedded in one side of the sealed door.

[0008] Furthermore, multiple rollers are fixedly connected to the bottom of the placement plate.

[0009] Furthermore, a handle is provided on one side of the U-shaped support plate.

[0010] Furthermore, a vacuum pump is fixedly connected to the top outer wall of the heating box, and an air inlet pipe is sealed and inserted into the air inlet end of the vacuum pump, while the other end of the air inlet pipe is sealed and inserted into the top of the heating box.

[0011] Furthermore, a motor is fixedly connected to one end of the outer wall of the heating box, a lead screw is keyed to the output end of the motor, a slider is threaded to the outer wall of the lead screw, and the top of the slider is fixedly connected to the bottom of the placement plate.

[0012] Furthermore, a mounting plate is fixedly connected to the bottom inner wall of the heating box, and one end of the lead screw is rotatably mounted to the mounting plate through an interlocking bearing. A lower support plate is fixedly connected to one side of the mounting plate, and a roller rolls on the lower support plate. The lower support plate is provided with a sliding hole, and the slider slides in the sliding hole.

[0013] Furthermore, a guide rod is fixed on the extrusion plate, and the guide rod is sealed and inserted into the heating box and the side plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By setting up a U-shaped support plate and support plate slots, the two slots simultaneously limit the U-shaped support plate, preventing it from shaking and allowing it to be pulled out. This helps to fix vertically placed laminated glass, preventing it from tipping over when being moved into or out of the heating chamber. At the same time, the U-shaped support plate, made of nickel-based alloy plate, serves as a pressure transmission component. Its pressure-resistant material prevents it from easily deforming, ensuring that pressure can be transmitted.

[0016] 2. By setting up the support plate, the device can simultaneously heat-press multiple pieces of glass. The extrusion plate extrudes the U-shaped support plate, and the U-shaped support plate extrudes the laminated glass. Since their contact surfaces are the same size, the extrusion pressure is evenly distributed. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Reference Figures 1-6 A hot pressing device for laminated glass processing includes a heating box 1. A control panel is fixed to one outer wall of the heating box 1 by bolts. A placement plate 14 is provided inside the heating box 1. Multiple support plates 16 are fixed to the top of the placement plate 14 by bolts. The support plates 16 have slots 17 on both sides. U-shaped support plates 18 are inserted into the slots 17. The depth of the slots 17 is greater than the height of the bend of the U-shaped support plates 18.

[0027] The U-shaped support plate 18 has all sides perpendicular to each other. The U-shaped support plate 18 is a nickel-based alloy plate. The glass to be hot-pressed is placed between the U-shaped support plate 18 and the slot 17. When placing it, first put the glass into contact with the vertical surface inside the U-shaped support plate 18, and then slowly insert the U-shaped support plate 18 into the slot 17 to fix the glass vertically.

[0028] A motor 10 is fixed to one end of the outer wall of the heating box 1 by bolts. A lead screw 11 is keyed to the output end of the motor 10. A mounting plate 9 is welded to the bottom inner wall of the heating box 1. One end of the lead screw 11 is rotatably mounted to the mounting plate 9 by an interlocking bearing.

[0029] The outer wall of the lead screw 11 is threaded with a slider 12. The top of the slider 12 is fixedly connected to the bottom of the placement plate 14. The motor 10 rotates slowly, driving the lead screw 11 to rotate, thereby driving the slider 12 to move, and then driving the placement plate 14 to move, so as to move the clamped glass into or out of the heating box 1. The two slots 17 simultaneously limit the U-shaped support plate 18, so that the U-shaped support plate 18 will not shake and can only be taken out by pulling.

[0030] Multiple rollers 15 are fixed to the bottom of the placement plate 14 by bolts. A lower support plate 13 is welded to one side of the mounting plate 9. The rollers 15 roll on the lower support plate 13, thereby rolling on the lower support plate 13. The lower support plate 13 is provided with a sliding groove, and the slider 12 slides in the sliding groove.

[0031] The heating box 1 has mounting openings on both sides and top, and multiple heating wires 8 are fixedly connected in the mounting openings. The heating wires 8 are electrically connected to the control panel.

[0032] Side plates 7 are fixedly connected to the outside of the mounting port by bolts. Hydraulic cylinders 20 are fixedly installed on the side plates 7 on both sides of the heating box 1 by bolts. The control system of the hydraulic cylinders 20 is connected to the control panel by wires. An extrusion plate 22 is welded and fixed to one end of the piston rod of the hydraulic cylinder 20 that passes through the side plate 7. The extrusion plate 22 can contact the outer wall of the U-shaped support plate 18. The extrusion plate 22, the U-shaped support plate 18, and the contact surface of the glass to be hot-pressed are the same size.

[0033] One end of the heating box 1 is connected to a sealing door 2 via a hinge. A handle 3 is fixed to one side of the outer wall of the sealing door 2 by bolts. Pulling the handle 3 outward will cause the sealing door 2 to rotate, thereby opening the sealing door 2. An observation window 4 is embedded on one side of the sealing door 2 so as to observe the hot pressing of the laminated glass.

[0034] A vacuum pump 5 is bolted to the top outer wall of the heating chamber 1. An air inlet pipe 6 is sealed and inserted into the air inlet end of the vacuum pump 5. The other end of the air inlet pipe 6 is sealed and inserted into the top of the heating chamber 1. Under the action of the vacuum pump 5, the gas in the heating chamber 1 is drawn into the air inlet pipe 6 and then discharged from the air outlet end of the vacuum pump 5, thereby performing a vacuuming operation on the heating chamber 1. A handle 19 is provided on one side of the U-shaped support plate 18 for easy operation.

[0035] The placement plate 14, support plate 16, U-shaped support plate 18, mounting plate 9, lead screw 11, slider 12, roller 15, extrusion plate 22, etc. are all made of high temperature resistant and pressure resistant metal materials, such as aluminum-magnesium alloy, titanium alloy, nickel-based alloy, etc., to prevent extrusion deformation and avoid failure caused by uneven heat and pressure.

[0036] The working principle of this embodiment is as follows: When in use, first, pull the handle 3 outward to rotate the sealing door 2, thereby opening the sealing door 2. Then, start the motor 10 through the control panel. Under the drive of the motor 10, the lead screw 11 rotates, thereby driving the slider 12 to move, and then driving the placement plate 14 to move outward.

[0037] Then, the laminated glass is attached to the vertical surface inside the U-shaped support plate 18, and the U-shaped support plate 18 is slowly inserted into the slot 17 to fix the glass vertically. Since the surfaces of the U-shaped support plate 18 are perpendicular to each other, the slot 17 provides support for the U-shaped support plate 18 after it is inserted into the slot 17, so that it will not move easily and can remain stable.

[0038] Alternatively, U-shaped support plates 18 can be inserted on both sides of the support plate 16 at the same time, so that the two pieces of glass can be hot-pressed at the same time.

[0039] Next, the motor 10 is reversed via the control panel. Driven by the motor 10, the placement plate 14 and the clamping glass above it are moved into the heating box 1, and then the sealing door 2 is closed.

[0040] Next, the vacuum pump 5 is started by controlling the control panel. Under the action of the vacuum pump 5, the gas in the heating box 1 is drawn into the air inlet pipe 6 and then discharged from the air outlet of the vacuum pump 5, thereby evacuating the heating box 1. At the same time, the heating wire 8 is heated by controlling the control panel to heat the inside of the box. Then, the hydraulic cylinders on both sides of the heating box 1 are extended by controlling the control panel, and the extrusion plate 22 begins to extrude the U-shaped support plate 18. The U-shaped support plate 18 extrudes the laminated glass onto the support plate 16, thereby performing hot pressing treatment on the laminated glass.

[0041] Example 2

[0042] The difference between this embodiment and embodiment 1 is that a guide rod 21 is fixed on the extrusion plate 22, and the guide rod 21 is sealed and inserted into the heating box 1 and the side plate 7, thereby making the stability better.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
