Description

Technical Field

[0001] This utility model relates to the field of industrial oven technology, and in particular to an industrial oven that provides uniform heating during baking. Background Technology

[0002] Industrial ovens are equipment used in industrial production for processes such as drying, curing, and heat treatment. Industrial ovens mainly work based on the principle of heat transfer. When the heating system is started, heat is transferred to the heated object through three methods: conduction, convection, and radiation. Conduction refers to the transfer of heat to the surface of the object through solid media such as the inner wall and shelves of the oven.

[0003] Currently available industrial ovens require placing the materials to be baked on racks and pushing the racks into the oven for baking. However, because the racks are made of metal, their surface temperature becomes too high after baking, which can easily cause burns to workers when pushing or pulling them, thus affecting normal operations.

[0004] Chinese patent publication number CN217179079U discloses an industrial drying oven, including a box body and an air outlet. The box body is equipped with a sealed door, and a heating fan is installed at the top of the box body. The heating fan is connected to the air outlet through the box body, and an airflow guiding mechanism is connected to the air outlet. A heating device is installed on the side of the box body, and a control panel is provided on the heating device. A connecting plate is connected to the side of the heating device, and a base plate is installed on the connecting plate. A spring is connected to the upper surface of the base plate, and a heating block is provided at the end of the spring away from the base plate. A corrugated pipe connected to the base plate is provided at the lower end of the heating block. This utility model, by setting a pipe connected to the air outlet inside the box body, can evenly conduct hot air to the internal space of the box body through the air outlet, thereby heating the interior of the box body in conjunction with the airflow guiding mechanism, and achieving dual heating treatment through the heating device, increasing the heating efficiency of the entire device. While this patent document achieves dual heating treatment and increases heating efficiency, it also poses a risk of burns when pushing or pulling material racks. Utility Model Content

The support frame is also partially moved outside the oven to cool down, ensuring the safety of the workers.

[0006] In order to solve the above-mentioned technical problems, the present invention solves the problem that industrial ovens need to place materials on metal racks for baking, but the high temperature of the metal racks can easily burn workers and affect their work.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An industrial oven for baking with uniform heating, comprising an oven body, and further comprising:

[0009] A closed door is installed on the oven body. At least two guide rails are fixed on the oven body. Several support legs are fixed on the guide rails.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This invention provides an industrial oven for evenly heated baking. Through the setting of a positioning mechanism, the position of the support frame can be effectively and precisely controlled during the process of completely pushing the support frame into the oven body. This mechanism ensures that the support frame can be accurately positioned in the designated position inside the oven, thereby avoiding possible displacement problems of the support frame during operation, or the situation where it fails to accurately reach the predetermined position, thus ensuring the stability and reliability of the entire baking process.

[0022] This utility model provides an industrial oven for even heating during baking. By setting up a pushing component, the support frame can be pushed a certain distance outside the oven after the baking operation is completed, preventing the support frame surface from overheating and causing burns to the workers.

Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0035] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0036] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0037] Example 1: Please refer to Figure 1 - Figure 8 An industrial oven for uniform heating includes an oven body 1; it also includes: a closed door 2 installed on the oven body 1; at least two guide rails 3 are fixed on the oven body 1; several support legs 4 are fixed on the guide rails 3; a support frame 5 is installed on the guide rails 3; the support frame 5 is slidably connected to the guide rails 3 via pulleys 6; a cooling unit 7 is installed on the oven body 1 for cooling the support frame 5; and a positioning mechanism 8 installed on the oven body 1 for limiting the position of the support frame 5; two handles are added to the support frame 5 to facilitate the movement of the support frame 5 by the operator.

[0038] The length of the support frame 5 is the same as the internal length of the oven body 1. By setting the length of the support frame 5, it can be ensured that the support frame 5 is completely located inside the oven body 1 for baking operations. The length of the guide rail 3 is greater than the sum of the lengths of the oven body 1 and the support frame 5. By setting the length of the guide rail 3, it can be ensured that the movement trajectory of the oven body 1 meets the baking requirements.

[0039] In addition, a pad is fixed on the side of the support leg 4 away from the guide rail 3. The addition of the pad improves the stability of the guide rail 3 when it is under force. Several pads are fixed on the bottom surface of the oven body 1. The pads provide support for the oven body 1.

[0040] It should be noted that the oven body 1 is equipped with a heating system, which mainly consists of heating tubes and heating plates. When current passes through, the heating wire generates heat, which in turn heats the surrounding air. The heating plate transfers heat to the objects inside the oven body 1 through thermal radiation. This system is suitable for applications where high temperature uniformity is required, so as to achieve precise temperature control of the oven body 1. This is a standard setting in the field, so it will not be described in detail here.

[0041] It should also be noted that the oven body 1 adopts a multi-layer structure. By filling the middle of the oven body 1 with heat insulation material, heat loss to the outside can be effectively reduced, energy consumption can be reduced, and the outer surface temperature of the oven body 1 can be kept from getting too high to avoid burns to the operators. In addition, a sealing material is set between the closed door 2 and the oven body 1 to prevent hot air leakage and ensure the temperature inside the oven is stable and uniform.

[0042] It is worth noting that the support frame 5 adopts a frame structure, and the top of the support frame 5 is composed of several rods arranged in parallel. This makes it convenient for workers to hang materials on the support frame 5, avoiding excessive obstruction that could affect the baking effect of the materials, and thus ensuring that the materials are baked in a uniform state.

[0043] Furthermore, the positioning mechanism 8 includes: a bracket 14 fixed on the oven body 1, with sliders a15 and b16 slidably connected to the bracket 14 respectively, a connecting rod 17 hinged between sliders a15 and b16, a spring 18 fixed between slider a15 and the bracket 14, a limiting sleeve 19 fixed on the support frame 5, and a limiting plate 20 adapted to the limiting sleeve 19 fixed on slider b16. One side of the support frame 5 is chamfered, and one side of the limiting plate 20 is chamfered like that of the support frame 5. A cylinder 21 is fixed on the oven body 1. A channel for the cylinder 21 to pass through is opened on the bracket 14. A mounting block 22 is fixed on the slider a15. The output end of the cylinder 21 is fixed to the mounting block 22. At least two sliding grooves 31 are opened on the bracket 14. Guide blocks 32 are fixed on both the slider a15 and the slider b16. The guide blocks 32 are slidably connected to the inside of the sliding grooves 31. The cross-section of the guide blocks 32 is T-shaped. A guide groove 33 is opened on the oven body 1. The mounting block 22 is slidably connected inside the guide groove 33.

[0044] The oven body 1 is provided with a pushing assembly 23 adapted to the support frame 5. The pushing assembly 23 includes: at least two mounting plates 24 fixed on the mounting block 22; at least two boxes 25 fixed on the oven body 1; two channels 26 are opened between the boxes 25 and the oven body 1; toothed plates a27 and b28 are slidably connected in the two channels 26 respectively; toothed plates a27 are fixed to the mounting plates 24; toothed plates b28 abut against the support frame 5; a rotating shaft 29 is rotatably connected to the boxes 25; a spur gear 30 is fixed on the rotating shaft 29; and the spur gear 30 meshes with the toothed plates a27 and b28.

[0045] It should be noted that, through the setting of the positioning mechanism 8, the position of the support frame 5 can be effectively and precisely limited during the process of pushing the support frame 5 completely into the oven body 1. This mechanism ensures that the support frame 5 can be accurately positioned in the designated position inside the oven, thereby avoiding the displacement problem that may occur during the operation of the support frame 5, or the situation that it fails to reach the predetermined position accurately, thus ensuring the stability and reliability of the entire baking process.

[0046] It should also be noted that by setting the pushing component 23, the support frame 5 can be pushed a certain distance away from the oven body 1 after the baking operation is completed, so as to prevent the surface of the support frame 5 from overheating and causing burns to the staff when the baking operation is just completed. Pushing part of the support frame 5 to the outside of the oven body 1 to cool down before pushing it away provides a certain degree of protection for the staff.

[0047] The principle of positioning the support frame 5 using the positioning component is as follows: by fully pushing the support frame 5 into the oven body 1, the cylinder 21 drives it forward, causing the mounting block 22 to move along the guide groove 33 after being subjected to force, which drives the slider a15 to move synchronously. At this time, the spring 18 is in a compressed state, and with the transmission action of the connecting rod 17, the slider b16 is subjected to force and moves upward along the slide groove 31 until the limiting plate 20 and the limiting sleeve 19 are engaged, thereby completing the positioning of the support frame 5.

[0048] In this plan, the baking process is as follows:

[0049] First, hang the material to be baked on the support frame 5. After opening the closed door 2, push the support frame 5 into the oven body 1. The positioning mechanism 8 positions the support frame 5 to ensure that the support frame 5 is pushed into place.

[0050] Next, the sealing door 2 is closed, and the heating system heats the inside of the oven body 1. When the preset time is reached, the sealing door 2 can be opened, and the mounting block 22 is moved by the cylinder 21, so that the slider a15 moves synchronously. The transmission action of the connecting rod 17 causes the limiting plate 20 to separate from the limiting sleeve 19, which drives the toothed plate a27 to move forward synchronously. The meshing transmission action between the toothed plate a27 and the spur gear 30 causes the rotating shaft 29 to rotate under force. In conjunction with the meshing transmission action between the spur gear 30 and the toothed plate b28, the toothed plate b28 comes into contact with and is pressed against the support frame 5, causing the support frame 5 to move under force.

[0051] Finally, the fan 10 drives the airflow, which causes the cold air to be discharged through the pipe 12 into the air collection hood 11. The air collection hood 11 sprays the cold air onto the support frame 5, thereby cooling the temperature of the support frame 5, so that the staff can manually push the support frame 5 to a suitable position.

[0052] Example 2: Based on Example 1, according to Figure 1 - Figure 5As shown, it is worth noting that the cooling unit 7 includes: a base 9 fixed on the oven body 1, a fan 10 fixed on the base 9, a gas collection hood 11 fixed on the oven body 1, a connecting pipe 12 between the air outlet of the fan 10 and the gas collection hood 11, and a grid 13 fixed on the fan 10 for filtering the air at the air inlet of the fan 10.

[0053] The gas collecting hood 11 is located directly above the two closed doors 2. The cross-section of the gas collecting hood 11 is trapezoidal. By setting the gas collecting hood 11, the portion of the support frame 5 exposed outside the oven body 1 can be cooled over a larger area.

[0054] It should be noted that the cooling unit 7 enables rapid cooling of the support frame 5 exposed outside the oven, thereby saving the time required for natural cooling and allowing staff to come into contact with the support frame 5 in a short time, further improving the efficiency of the baking process.

[0055] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
