Description

Technical Field

[0001] This application relates to the field of fireproof core material processing technology, specifically a fireproof core material oven preheating device. Background Technology

[0002] In modern industry, the application of fire-retardant materials is becoming increasingly widespread. Whether in the construction industry, transportation, or electronics, the demand for fire-retardant materials continues to grow. As a key component of fire-retardant materials, the processing quality of the fire-retardant core material directly affects the performance and effectiveness of the fire-retardant material. Before further processing or treatment, the fire-retardant core material is heated to a certain temperature using this device to bring it to a suitable state for subsequent processing. For example, when combining the fire-retardant core material with other materials, preheating can improve the adhesion between the core material and other materials.

[0003] For example, the patent with publication number CN217083229U discloses an automatic feeding thermal insulation cotton core material drying tunnel, which includes a base plate, drying oven, support rod, rotary motor, rotating rod, conveyor belt, feeding box, spring, dropping plate, switch, rotary motor, fixing rod and baffle, thereby realizing automatic transmission of thermal insulation cotton core material for drying, while the internal cotton core material is damaged and falls off when it falls.

[0004] The aforementioned patent describes a method for drying fire-retardant core materials using a conveyor belt. However, in practical use, it has been found that the side of the fire-retardant core material in contact with the conveyor belt cannot be adequately dried. This results in uneven heating of the core material, leading to inconsistent temperatures between areas closer to the heating source and areas further away, causing inconsistent changes in the core material's properties. Therefore, it is necessary to provide a preheating device for a fire-retardant core material drying oven to address these issues.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figures 1-3 As shown, this application provides a preheating device for a fireproof core material oven, including a transmission assembly 1. The transmission assembly 1 includes a transmission belt 11 and side frames 12 disposed at both ends of the transmission belt 11. The transmission belt 11 has multiple sets of through grooves (not shown in the figure), which are suitable for the fireproof core material to be heated on both the top and bottom surfaces. A support leg 13 is fixedly installed at the bottom of the side frame 12, and the support leg 13 is used to support the transmission assembly 1.

[0026] And a preheating assembly 2 is installed on two sets of side frames 12. Two sets of the preheating assembly 2 are symmetrically arranged in the upper and lower parts. In this application, only one set of the preheating assembly 2 is shown to preheat both the upper and lower surfaces of the fireproof core material. The preheating assembly 2 includes a processing box 21 fixedly installed on the two sets of side frames 12. The processing box 21 has a preheating chamber 22 inside, and an electric heating wire 23 is fixedly installed inside the preheating chamber 22.

[0027] When the device is started, the electric heating wire 23 is energized and generates heat, raising the air temperature inside the preheating chamber 22 and creating a hot air environment. As the conveyor belt 11 rotates, the fireproof core material enters between the upper and lower preheating components 2. At this time, the upper surface of the fireproof core material is subjected to heat transfer from the hot air in the upper preheating component 2 (mainly through convection and radiation), while the lower surface is subjected to heat transfer from the hot air in the lower preheating component 2. Because the preheating components 2 are symmetrically arranged, and the through-slot design of the conveyor belt 11 allows both the upper and lower surfaces to be exposed to hot air, the upper and lower surfaces of the fireproof core material can absorb heat simultaneously and relatively evenly, achieving preheating treatment of the fireproof core material.

[0028] The conveyor belt 11 operates continuously, conveying the fireproof core material through the preheating component 2 area, so that the fireproof core material is continuously preheated on the upper and lower surfaces during the movement until the required preheating effect is achieved, and then it is conveyed out of the preheating device to enter the subsequent processing or treatment process.

[0029] An angle adjustment assembly 3 is installed through the processing box 21. The angle adjustment assembly 3 includes a mounting box 310 that is fixedly installed through the processing box 21. Two blowing units are installed inside the mounting box 310. Each blowing unit includes a fixed shaft 31 with bearings mounted on the inner wall of the mounting box 310. A blower 32 is fixedly sleeved on the fixed shaft 31. The blower 32 has two sets of fixing blocks 33. The blower 32 is fixedly sleeved with the fixed shaft 31 through the fixing blocks 33. The blower 32 is adapted to rotate along the axis of the fixed shaft 31.

[0030] Furthermore, the two ends of the fixed shaft 31 are fixedly installed with first gears 34. It should be noted here that the blowing unit on the left side is defined as the first blowing unit, the blowing unit on the right side is defined as the second blowing unit, and the second blowing unit having the first gear 34 is defined as the second gear.

[0031] Meanwhile, cylinders 35 are fixedly installed on both sides of the mounting box 310. Each cylinder 35 has a telescopic shaft 36, and a first rack 37 is fixedly installed at one end of the telescopic shaft 36. The first rack 37 meshes with the first gear 34. At the same time, a second rack 38 is connected and fixed on the first rack 37. The second rack 38 meshes with the second gear. It should be noted that the first rack 37 and the second rack 38 are arranged opposite to each other.

[0032] When the telescopic shaft 36 of cylinder 35 extends or retracts, it drives the first rack 37 to move synchronously. Since the first rack 37 meshes with the first gear 34, the linear motion of the first rack 37 is converted into the rotation of the first gear 34, which in turn drives the fixed shaft 31 and the blower 32 fixed thereon to rotate. Similarly, the second rack 38, connected to the first rack 37, also moves synchronously. The second rack 38 meshes with the second gear, causing the second gear to rotate, which in turn drives the blower 32 on the other side to rotate.

[0033] Because the two sets of blowers 32 rotate through the aforementioned transmission structure, and the design aims to bring the air outlets of the two sets of blowers 32 closer to or further apart from each other. When the cylinder 35 drives the first rack 37 and the second rack 38 to move to one side, the two sets of blowers 32 will rotate synchronously, causing their air outlets to gradually move closer to each other; when the cylinder 35 drives the first rack 37 and the second rack 38 to move to the other side, the two sets of blowers 32 will rotate in opposite directions, and their air outlets will gradually move further apart from each other.

[0034] By adjusting the position of the blower 32 outlet as described above, the outlet angle and relative position of the two sets of blowers 32 can be flexibly adjusted according to the different widths of the fireproof core material. When the fireproof core material is wide, the outlets of the two sets of blowers 32 can be adjusted to be further apart to ensure that hot air can cover the entire width of the core material; when the fireproof core material is narrow, the outlets of the two sets of blowers 32 can be adjusted to be closer together to concentrate hot air to preheat the core material, thereby improving thermal efficiency and the uniformity of preheating effect.

[0035] Furthermore, protective covers 39 are fixedly installed on both sides of the mounting box 310. These protective covers 39 are used to protect the cylinder 35, the first gear 34, and the second rack 38 to prevent foreign objects from entering and causing the components to jam, thereby reducing the risk of mechanical damage. A dustproof plate 311 is slidably inserted into the side of the mounting box 310. The dustproof plate 311 has multiple sets of filter holes to protect the blower 32 from dust. At the same time, a receiving groove is provided on the inner wall of the mounting box 310. This receiving groove is suitable for supporting the dustproof plate 311 when it is inside the mounting box 310. A handle 312 is fixed to the side of the dustproof plate 311, which is suitable for pulling the dustproof plate 311 out from the side of the mounting box 310.

[0036] In summary: the through-slot design on the conveyor belt 11 allows the upper and lower surfaces of the fireproof core material to be directly exposed to hot air. Through convection and radiation heat transfer, the upper and lower surfaces are heated synchronously and uniformly, achieving initial preheating.

[0037] The angle adjustment component 3 further optimizes the preheating effect. The blowers 32 of the two blowing units inside the mounting box 310 are connected to the fixed shaft 31 via a fixing block 33, allowing them to rotate around the shaft. When the cylinder 35 is activated, its telescopic shaft 36 drives the first rack 37 to move linearly. The first rack 37 meshes with the first gear 34, converting this into rotation of the first gear 34, which in turn drives the fixed shaft 31 and the blowers 32 to rotate. Simultaneously, the second rack 38, connected to the first rack 37, moves synchronously, driving the second gear to rotate, causing the blowers 32 on the other side to rotate synchronously. Through this transmission structure, the distance between the air outlets of the two sets of blowers 32 can be flexibly adjusted. For fireproof core materials of different widths, the outlet positions can be adjusted as needed: when the core material is wider, the outlets are spaced further apart to ensure comprehensive coverage of hot air; when the core material is narrower, the outlets are brought closer together for concentrated heating, significantly improving thermal efficiency and preheating uniformity.

[0038] In addition, to ensure the long-term stable operation of the equipment, protective covers 39 are installed on both sides of the mounting box 310 to strictly protect key components such as the cylinder 35, the first gear 34, and the second rack 38, preventing foreign objects from entering and causing jamming or mechanical damage. The side-mounted dustproof plate 311, with its multiple filter holes, filters the air entering the mounting box 310, preventing dust from affecting the performance of the blower 32. The receiving slot provides support when the dustproof plate 311 slides in; when cleaning or replacing the dustproof plate 311 is required, the operator only needs to pull it out using the handle 312, making maintenance very convenient.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
