[0035] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper" and "lower" are used interchangeably with... Figure 1 With the orientation as a reference, the direction of the door panel assembly 1 is "front", the opposite side is "back", the direction of the furnace assembly 2 is "up", and the direction of the base assembly 3 is "down".

[0036] This utility model discloses a glazing kiln, including a door panel assembly, a furnace liner assembly, and a base assembly. The furnace liner assembly is fixedly installed on the top surface of the base assembly, and the left side of the door panel assembly is rotatably connected to the furnace liner assembly. The door panel assembly, from front to back, includes an outer door panel, a movable plate, a compression spring, and a door liner unit. The door liner unit is used to cover the furnace liner assembly. The outer door panel is fixedly connected to the movable plate, and the movable plate and the door liner unit are elastically connected by the compression spring. A door lock unit is provided on the right side of the outer door panel. The door lock unit is used to lock the door panel assembly and the furnace liner assembly. When the door lock unit locks the door panel assembly and the furnace liner assembly, the movable plate compresses the compression spring, generating an inward thrust, so that the door liner unit and the furnace liner are tightly fitted, sealing the furnace liner assembly. Its beneficial effect is that the rebound force of the compression spring enhances the sealing performance of the door liner unit and the furnace liner assembly, reduces heat loss, thereby improving heating efficiency and heat preservation effect, and can solve the technical problem of poor sealing and heat preservation effect of the door panel and furnace liner of existing glazing kilns.

[0037] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0038] Example:

[0039] Reference Figures 1 to 3 This embodiment provides a glazing furnace, including a door panel assembly 1, a furnace chamber assembly 2, and a base assembly 3.

[0040] The furnace chamber assembly 2 is fixedly installed on the top surface of the base assembly 3, and the left side of the door panel assembly 1 is rotatably connected to the furnace chamber assembly 2. The door panel assembly 1, from front to back, includes an outer door panel 10, a movable plate 11, a compression spring 12, and a door chamber unit 13. The door chamber unit 13 is used to cover the furnace chamber assembly 2. The outer door panel 10 is fixedly connected to the movable plate 11, and the movable plate 11 and the door chamber unit 13 are elastically connected by the compression spring 12. A door lock unit 14 is provided on the right side of the outer door panel 10, which is used to lock the door panel assembly 1 and the furnace chamber assembly 2 tightly together. When the door lock unit 14 locks the door panel assembly 1 and the furnace chamber assembly 2, the movable plate 11 compresses the compression spring 12, generating an inward thrust. The thrust of the compression spring 12 creates uniform pressure between the door chamber unit 13 and the furnace chamber assembly 2, ensuring a tight fit between the door chamber unit 13 and the furnace chamber, thus sealing the furnace chamber assembly 2.

[0041] See Figure 4A lock body fixing component 102 is provided on the back of the right side of the outer door panel 10, and two latch limiting posts 103 are provided on the lock body fixing component 102. The door lock unit 14 includes a handle 141, a pressure cover 140, a bushing 142, a limiting screw 143, a door lock main shaft 144, a return spring 145, a door lock fastener 146, and a lock tongue plate 147. The front end of the handle 141 and the pressure cover 140 are exposed on the front of the outer door panel 10. The handle 141 passes through the pressure cover 140, the bushing 142, and the nut in sequence and is inserted into the hole of the door lock main shaft 144, and is fixedly connected together by the limiting screw 143. The door lock main shaft 144 extends from the rear side of the lock body fixing component 102. The handle 141 and the door lock main shaft 144 are rotated and engaged with the bushing 142 as a whole, and the bushing 142 is threadedly connected to the nut and clamped and fixed together with the outer door panel 10. A door lock fastener 146 is fitted onto the rear end of the door lock spindle 144, and the front side of the door lock fastener 146 abuts against the lock body fixing member 102. A limiting screw 143 passes through the rear side of the door lock fastener 146 on the door lock spindle 144 to restrict the forward and backward movement of the door lock fastener 146. The door lock fastener 146 has symmetrically arranged locking protrusions on its upper and lower sides, which cooperate with the lock buckle limiting post 103 to limit the rotation angle of the door lock spindle 144 and prevent the handle 141 from being over-rotated. The latch plate 147 is bolted to the rear end of the door lock spindle 144. A return spring 145 is also fitted onto the door lock spindle 144 to help the handle 141 automatically return to its original position. One end of the return spring 145 is fixed to the outer door panel 10, and the other end is fixed to the door lock fastener 146. The furnace liner assembly 2 is provided with a lock hole adapted to the latch plate 147. By rotating the handle 141, the direction of the latch plate 147 in the keyhole is changed, so that the latch plate 147 is locked in the keyhole or retracted from the keyhole, thereby unlocking or locking.

[0042] Continue reading Figure 4 The door frame unit 13 includes a door frame fixing plate 132, a door panel outer frame 133, a pad plate 131, a side panel mounting component 134, and a side panel body 135. The pad plate 131 and the side panel mounting component 134 are respectively installed on the front side of the door frame fixing plate 132. The two side panel bodies 135 are respectively fixedly connected to the two sides of the side panel mounting component 134. The door panel outer frame 133 is placed on the back side of the door frame fixing plate 132 and is snapped together with the side panel body 135.

[0043] like Figure 5As shown, the pad 131 is welded and fixed to the door liner fixing plate 132. A threaded post is welded to the front of the door liner fixing plate 132, and the threaded post passes through the pad 131 and the movable plate 11 in sequence. A bolt passes through the movable plate 11 and is threadedly connected to the threaded post. A compression spring 12 is sleeved on the threaded post and located between the pad 131 and the movable plate 11. Therefore, when the door lock unit 14 is locked to the furnace liner assembly 2, the movable plate 11 is forced to move backward, compressing the compression spring 12. The rebound force of the compression spring 12 causes the door liner unit 13 to press against the furnace liner assembly 2, enhancing the sealing between the door liner unit 13 and the furnace liner assembly 2, reducing heat loss, thereby improving heating efficiency and heat preservation effect. The heating effect of the furnace liner assembly 2 is better, which can solve the technical problem of poor sealing and heat preservation effect of the existing glazing kiln door panel and furnace liner.

[0044] In some feasible solutions, four threaded posts are evenly distributed at the four corners of the door panel fixing plate 132, and four corresponding compression springs 12 are provided. These effectively apply force to the outer door panel 133, pressing it tightly against the furnace assembly 2, thus improving the sealing and insulation effect. The compression springs are made of high-temperature alloy material, such as a nickel-based high-temperature alloy, with a stiffness coefficient of 48 N / mm. The initial pre-compression is 6 mm, increasing to 12 mm after locking, generating a single spring thrust of 240 N. The four sets of springs provide a total sealing thrust of 960 N, ensuring a tight fit between the metal mating surfaces of the door panel unit 13 and the furnace shell 21. In actual use, the number and parameters of the compression springs 12 are adjusted according to the actual situation of the door panel assembly.

[0045] See Figure 4 In actual production applications, two U-shaped plates 101 are symmetrically welded to the back of the outer door panel 10. The two U-shaped plates 101 are perpendicular to the ground and their openings face the outer door panel 10. Bolts pass through the movable plate 11 and connect it to the U-shaped plates 101, making the movable plate 11 and the outer door panel 10 a whole. When the outer door panel 10 is locked to the furnace assembly 2 through the door lock unit 14, the movable plate 11 is thus subjected to force to compress the spring 12, thereby pressing the outer door panel 133 tightly against the front of the furnace assembly 2.

[0046] See Figure 6In some feasible solutions, the furnace assembly 2 includes a furnace shell 21, an inner furnace body 22, a support plate 23, an aluminum plate 24, and a temperature controller 221. The inner furnace body 22 uses an existing furnace shell. The temperature controller 221 is installed on the rear side of the inner furnace body 22 to monitor the operating temperature of the inner furnace body 22. The temperature controller 221 is a thermocouple, connected to the control circuit board 32 via wires, and collects temperature data in real time and feeds it back to the display screen 31. The temperature controller 221 adjusts the heating power in real time through the control circuit board 32, and automatically cuts off the power when the temperature exceeds the preset temperature. The inner furnace body 22 and the support plate 23 are fixed together, and the lower end of the support plate 23 is bolted to the aluminum plate 24. The furnace shell 21 covers the inner furnace body 22 and is bolted to the aluminum plate 24. The aluminum plate 24 covers the top surface of the base assembly 3 and is connected to the base assembly 3.

[0047] In practical applications, the furnace liner assembly 2 also includes a U-shaped strip 26, which is used to snap onto the outer wall of the inner liner body 22 and to connect the support plate 23. Specifically, the inner wall of the U-shaped strip 26 fits against the outer wall of the inner liner body 22, and the lower end of the U-shaped strip 26 is connected to the support plate 23 by bolts to fix the inner liner body 22 and the support plate 23 together.

[0048] It should be noted that the front of the furnace shell 21 has a window, and the opening of the inner furnace body 22 is located in the window, revealing a U-shaped area within the window. When the door panel assembly 1 is locked, the edge of the outer door panel 133 is pressed together with the U-shaped area of ​​the inner furnace body 22, and the two together form the furnace structure.

[0049] like Figure 4 and Figure 6 As shown, a hinge connecting plate 111 is bolted to one side of the movable plate 11. The hinge connecting plate 111 is hinged to the furnace shell 21 through the hinge body 211. In other words, the door panel assembly 1 is hinged to the furnace shell 21, and the door panel assembly 1 opens to one side.

[0050] See Figure 2 and Figure 3 To ensure smoother opening and closing of the door panel assembly 1, the aluminum plate 24 is provided with a sliding groove, and a sliding member 105 is installed at the lower end of the outer door panel 10. The end of the sliding member 105 is bent downward at 90 degrees to form a hook-shaped structure, which is adapted to the sliding groove. When the door panel assembly 1 is opened or closed, the hook-shaped structure of the sliding member 105 slides in the sliding groove.

[0051] See Figure 6Furthermore, a limit switch 25 for detecting the opening and closing state of the door panel assembly 1 is installed on the bottom surface of the aluminum plate 24. The limit switch 25 adopts a commercially available switch. When the hook-shaped structure of the sliding member 105 slides in the sliding groove, a signal is triggered, and the control circuit board 32 cuts off the heating power. When the door is closed, the hook-shaped structure of the sliding member 105 at the lower end of the outer door panel 10 slides completely into the sliding groove, the limit switch 25 triggers a closing signal, and the control circuit board 32 starts the heating program; when the door is opened, the hook-shaped structure moves away from the sliding groove, the limit switch 25 disconnects and cuts off the heating power.

[0052] See Figure 7 The base assembly 3 includes a base plate 36, a base housing 30, a display screen 31, a control circuit board 32, and a control knob 33. The base plate 36 is bolted to the bottom surface of the base housing 30. The display screen 31 is mounted on the front of the base housing 30, and the control circuit board 32 is mounted inside the base housing 30, with a microprocessor connected to it. The control knob 33 is mounted on the front of the base housing 30, and the control knob 33, display screen 31, and temperature controller 221 are connected to the control circuit board 32 via wires. A power switch 34 and a power socket 35 are mounted on the rear wall of the base housing 30.

[0053] It should be noted that the outer door panel 10, the furnace shell 21, the base shell 30, and the bottom plate 36 are all provided with heat dissipation holes.
