Description
Technical Field
[0001] This utility model relates to the field of foaming furnace technology, and in particular to a natural gas burner for a foaming furnace. Background Technology
[0002] Foaming technology is widely used in many industries, from building insulation materials to daily packaging products. Foamed products are everywhere. As a key piece of equipment, the core component of the foaming furnace, the burner, is of paramount importance. The burner is the core component for achieving efficient heating in the foaming furnace. It is mainly made of high-temperature resistant metal. Through precisely designed gas channels and fire holes, natural gas is introduced and sprayed out in an orderly manner, providing continuous and uniform heat to the foaming material, which then completes the foaming process.
[0003] In existing general foaming furnaces, the overall horizontal position and height of the natural gas burner are mostly fixed, and the horizontal and height positions cannot be adjusted according to the actual needs of the operator, resulting in mediocre performance. At the same time, the flame jet angle of the burner is usually fixed vertically, and the angle of the burner cannot be adjusted according to the actual needs of the operator.
[0004] Based on this, a natural gas burner for a foaming furnace is now provided, which can optimize the shortcomings of existing devices. Utility Model Content

A threaded rod is fixedly connected to the drive end of the second drive motor. A slider is threadedly connected to the outside of the threaded rod. The slider is connected to the lower end of the X-shaped telescopic frame. As the slider moves horizontally, the X-shaped telescopic frame will change the cross angle to adjust the height of the upper frame.
[0009] In a preferred embodiment, the X-shaped telescopic frame includes two fixed rods fixedly connected to the front and rear sides of the top of the lower frame. A sleeve is slidably connected to the outer right side of each fixed rod. A connecting plate is fixedly connected to the top of each sleeve.

A connecting plate is fixedly connected to the front and rear of the left side of the lower frame. A connecting rod is rotatably connected to each connecting plate on its opposite side. The other end of each connecting rod is rotatably connected to a connecting plate on its opposite side. The top of each connecting plate is fixedly connected to the bottom of a sleeve. The sleeves are slidably connected to the outer right side of the fixed rod. The fixed rods are fixedly connected to the front and rear sides of the bottom of the upper frame. Each connecting rod is connected to the connecting rod through a connecting shaft. The other end of each threaded rod is rotatably connected to one side of a fixed block. A connecting block is fixedly connected to the front and rear sides of the slider. The ends of the connecting blocks away from the slider are fixedly connected to the sleeves on their opposite sides.
[0010] In a preferred embodiment, the adjusting assembly includes a mounting base fixedly connected to the top of the upper frame. A fixing plate is fixedly connected to one side of the mounting base. A drive motor is fixedly connected to the top of the fixing plate. A transmission shaft is fixedly connected to the driving end of the drive motor. A gear is fixedly connected to the other end of the transmission shaft. The gear meshes with the gear.

[0015] As can be seen from the above, the natural gas burner for a foaming furnace provided by this utility model has the following technical effects.
[0016] Firstly, by using the lifting assembly, when the height of the fire vent needs to be adjusted, the operator starts the second drive motor to rotate the threaded rod, which in turn drives the slider to move. The movement of the slider is transmitted to the first sleeve through the first connecting block. The first sleeve slides on the second fixed rod, which drives the first connecting rod to move. The linkage mechanism composed of the first and second connecting rods starts to operate, and its included angle changes with the sliding of the first sleeve, causing the upper frame to rise or fall, thereby realizing the adjustment of the fire vent height.
[0017] Secondly, through the set adjustment components, the operator starts the drive motor one, which drives the transmission shaft one and gear two to rotate, and transmits the rotation of gear two to gear one, so that gear one and transmission shaft two rotate, and transmits to the burner body. The burner body rotates through the rotating shaft, and the connecting block two connected to the rotating shaft moves accordingly, causing the ball to slide in the through groove, so as to achieve precise adjustment of the angle of the burner body.

[0025] 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.
[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] Reference Figures 1-4 A natural gas burner for a foaming furnace includes a base 1. Fixing blocks 2 are fixedly connected to both sides of the top of the base 1. Fixing rods 3 are fixedly connected to the front and rear sides of one end of the fixing blocks 2. Mounting blocks 14 are slidably connected to the outer side of the fixing rods 14. An electric push rod 4 is fixedly connected to the middle of one side of the fixing block 2. The driving end of the electric push rod 4 is fixedly connected to one side of the mounting block 14. A lifting component is provided at the top of the mounting block 14. A mounting seat 5 is fixedly connected to the top of the lifting component. An adjustment component is provided inside the mounting seat 5.
[0028] The mounting base 5 has an upper frame 11 and a lower frame 15 on its top. An X-shaped telescopic frame is provided between the upper frame 11 and the lower frame 15. A fixing plate 2 13 is fixedly connected to the middle right side of the lower frame 15. A drive motor 2 12 is fixedly connected to the top of the fixing plate 2 13. A threaded rod 10 is fixedly connected to the drive end of the drive motor 2 12. A slider 25 is threadedly connected to the outside of the threaded rod 10. The slider 25 is connected to the lower end of the X-shaped telescopic frame. As the slider 25 moves horizontally, the X-shaped telescopic frame will change its cross angle to adjust the height of the upper frame 11.
[0029] In this embodiment, when using the natural gas burner in the foaming furnace, the operator first determines whether the lateral position of the burner needs adjustment based on the requirements of the foaming process. If adjustment is needed, the electric push rod 4 is activated, and the drive end of the electric push rod 4 begins to extend and retract, pushing or pulling the mounting block 14. The mounting block 14 slides on the fixed rod 3. Since the mounting block 14 is connected to the lifting assembly and the mounting base 5, the entire burner device will move laterally to a suitable position as the mounting block 14 slides, preparing for subsequent foaming work. When the height of the burner needs to be adjusted, the operator activates the drive motor 12, which drives the threaded rod 10 to begin... As the threaded rod 10 rotates, the slider 25 moves linearly along the threaded rod 10. The movement of the slider 25 is transmitted to the sleeve 18 through the connecting block 26. The sleeve 18 slides on the fixed rod 27. The sliding of the sleeve 18 drives the connecting rod 19 to move. The linkage mechanism composed of the connecting rod 19 and the connecting rod 21 starts to operate, so that its included angle changes with the sliding of the sleeve 18, causing the upper frame 11 to rise or fall, thereby realizing the adjustment of the height of the burner. The operator can precisely adjust the height of the burner by controlling the rotation time and direction of the drive motor 212 to meet the requirements of different foaming materials and processes for the height of the burner.
[0030] Reference Figures 1-4 In a preferred embodiment, the X-shaped telescopic frame includes a second fixed rod 17 fixedly connected to the front and rear sides of the top of the lower frame 15. A first sleeve 18 is slidably connected to the outer right side of each fixed rod 17. A fourth connecting plate 36 is fixedly connected to the top of each sleeve 18. A first connecting rod 19 is rotatably connected to each connecting plate 36 on its opposite side. The other end of each connecting rod 19 is rotatably connected to a second connecting plate 23. The second connecting plate 23 is fixedly connected to the front and rear sides of the bottom of the upper frame 11. A first connecting plate 22 is fixedly connected to the front and rear of the left lower frame 15. A first connecting plate 22 is rotatably connected to each connecting plate 22 on its opposite side. The other end of rod 21 and connecting rod 21 are rotatably connected to connecting plate 35 on opposite sides. The top end of connecting plate 35 is fixedly connected to the bottom end of sleeve 24. Sleeve 24 is slidably connected to the right side outside of fixed rod 34. Fixed rod 34 is fixedly connected to the front and rear sides of the bottom of upper frame 11. Connecting rod 19 is connected to connecting rod 21 through connecting shaft 20. The other end of threaded rod 10 is rotatably connected to one side of fixed block 29. Connecting block 16 is fixedly connected to the front and rear sides of slider 25. The end of connecting block 126 away from slider 25 is fixedly connected to sleeve 18 on opposite sides.
[0031] In this embodiment, when the drive motor 12 drives the threaded rod 10 to rotate, the slider 25 moves linearly along the threaded rod 10, and drives the sleeve 18 to slide on the fixed rod 17 through the connecting block 26. The sliding of the sleeve 18 causes the linkage mechanism composed of the connecting rod 19 and the connecting rod 21 to move. As the sleeve 18 slides, the angle of the connecting rod changes accordingly, and the upper frame 11 rises or falls, thereby realizing the adjustment of the fire vent height.
[0032] Reference Figure 1 , Figure 5 and Figure 6 In a preferred embodiment, the adjustment assembly includes a mounting base 5 fixedly connected to the top of the upper frame 11. A fixing plate 6 is fixedly connected to one side of the mounting base 5. A drive motor 7 is fixedly connected to the top of the fixing plate 6. A drive shaft 30 is fixedly connected to the drive end of the drive motor 7. A gear 33 is fixedly connected to the other end of the drive shaft 30. The gear 33 meshes with a gear 31. A drive shaft 32 is fixedly connected to the middle of the inner side of the gear 31. A burner body 8 is fixedly connected to one end of the drive shaft 32. A rotating shaft 16 is fixedly connected to the middle of the other end of the burner body 8. A connecting block 27 is fixedly connected to the top of the rotating shaft 16. A ball bearing 28 is rotatably connected to the other end of the connecting block 27. The ball bearing 28 is slidably connected to the inner side of the through groove 29.
[0033] In this embodiment, if the angle of the flame burner needs to be adjusted, the operator starts the drive motor 7. The drive end of the drive motor 7 drives the transmission shaft 30 to rotate, which in turn drives the gear 33 to rotate. The gear 33 meshes with the gear 31, transmitting the rotation of the gear 33 to the gear 31, causing the gear 31 to rotate in the opposite direction. The rotation of the gear 31 is transmitted to the flame burner body 8 through the transmission shaft 32. The flame burner body 8 rotates through the connected rotating shaft 16. During the rotation, the connecting block 27 connected to the rotating shaft 16 moves accordingly. The ball bearing 28 at the end of the connecting block 27 slides in the through groove 29. The through groove 29 provides space for the ball bearing 28 to move, ensuring the stability of the rotation of the flame burner body 8. The operator can precisely adjust the angle of the flame burner body 8 according to actual needs, so that the flame can accurately act on the foaming material, improving the foaming quality and efficiency.
[0034] Specifically, refer to Figure 6 The other end of the drive shaft 32 is fixedly connected to one side of the inner wall of the mounting base 5, which makes the drive shaft 32 more stable when rotating and can accurately transmit the rotation of the gear 31 to the fire plate body 8, ensuring the accuracy of the angle adjustment of the fire plate body 8.
[0035] Specifically, refer to Figure 5 The other end of the rotating shaft 16 is rotatably connected to the other side of the inner wall of the mounting base 5, providing a reliable support point for the rotation of the fire duct body 8, so that the fire duct body 8 can rotate smoothly through the rotating shaft 16 when the angle is adjusted.
[0036] Furthermore, refer to Figure 5 The through groove 29 is U-shaped, which provides sliding space for the ball bearing 28. When the angle of the burner body 8 is adjusted, the ball bearing 28 can slide flexibly in the U-shaped through groove 29. At the same time, the U-shaped structure also plays a certain limiting role for the ball bearing 28, limiting its maximum rotation angle, preventing the burner body 8 from rotating excessively, and ensuring the stability of the burner body 8 rotation.
[0037] Furthermore, refer to Figure 5 The connecting block 27 is set in an L shape, and the L-shaped connecting block 27 can effectively connect the rotating shaft 16 and the ball 28.
[0038] Working principle: When the device height needs to be adjusted, the electric push rod 4 is activated. The drive end of the electric push rod 4 begins to extend and retract, pushing or pulling the mounting block 14. The mounting block 14 slides on the fixed rod 3. Since the mounting block 14 is connected to the lifting assembly and the mounting seat 5, the entire fire grill device will move laterally to the appropriate position as the mounting block 14 slides, preparing for subsequent foaming work. When the height of the fire grill needs to be adjusted, the operator activates the drive motor 12, which drives the threaded rod 10 to rotate. As the threaded rod 10 rotates, the slider 25 moves linearly along the threaded rod 10. The movement of the slider 25 is transmitted to the sleeve 18 through the connecting block 26. The sleeve 18 slides on the fixed rod 17. The sliding of the sleeve 18 drives the connecting rod 19 to move. The linkage mechanism composed of the connecting rod 19 and the connecting rod 21 begins to operate, causing its included angle to change with the sliding of the sleeve 18, making the upper frame 11 rise or fall, thereby realizing the adjustment of the height of the fire grill body 8. Operators can precisely adjust the height by controlling the rotation direction of drive motor 12 to meet the requirements of different foaming materials and processes for the height of the burner. When it is necessary to adjust the angle of the burner body 8, the operator starts drive motor 7. The drive end of drive motor 7 drives transmission shaft 30 to rotate, which in turn drives gear 33 to rotate. Gear 33 meshes with gear 31, transmitting the rotation of gear 33 to gear 31, causing gear 31 to rotate in the opposite direction. The rotation of gear 31 is transmitted to the burner body 8 through transmission shaft 32. The burner body 8 rotates through the connected rotating shaft 16. During the rotation, connecting block 27 connected to the rotating shaft 16 moves accordingly. The ball bearing 28 at the end of connecting block 27 slides in the through groove 29. The through groove 29 provides space for the ball bearing 28 to move, ensuring the stability of the burner body 8's rotation. Operators can precisely adjust the angle of the burner body 8 according to actual needs, so that the flame can accurately act on the foaming material, improving foaming quality and efficiency.
[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
