Abstract
Description
Technical Field
[0001] This utility model relates to the field of tunnel furnace technology, specifically a tunnel furnace with good energy-saving effect. Background Technology
[0002] As is well known, energy-efficient tunnel ovens are industrial heating equipment that significantly reduces energy loss and improves energy utilization while achieving continuous heating processes (such as food baking, hardware drying, and plastic molding) by optimizing heating methods, thermal circulation systems, and insulation structures. Their core feature is that, while ensuring uniform heating temperature and process compliance, they reduce energy costs per unit product by minimizing heat radiation and heat conduction losses. They are also compatible with automated production lines and are widely used in industries such as food processing, electronic components, and automotive parts.
[0003] Existing energy-efficient tunnel furnaces have significant limitations in practical use: when the equipment is placed in the same working position for a long time, a certain gap will form between the bottom of the machine and the ground. Dust easily accumulates in this gap due to environmental dust settling and workpiece processing debris falling. Since existing equipment lacks a targeted bottom cleaning structure, to clean this accumulated dust, workers need to use external tools or equipment to move the entire tunnel furnace to another location, clean the dust at the original location, and then move the equipment back to its original position. The whole process is not only cumbersome but also consumes a lot of manpower and time, resulting in increased downtime for equipment maintenance. This indirectly affects the continuity of tunnel furnace heating operations and overall work efficiency, making it difficult to meet the actual needs of convenient equipment maintenance in industrial scenarios.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4A tunnel furnace with good energy-saving effect includes a body 1, a moving mechanism 2, and a cleaning mechanism 6. The moving mechanism 2 has several components, each including a sliding assembly 3, a sliding block 4, and a pulley assembly 5. The pulley assembly 5 is located at the bottom of the body 1, the sliding block 4 is mounted on the sliding assembly 3, and the pulley assembly 5 is mounted on the sliding block 4. The cleaning mechanism 6 includes a connecting plate 7, a T-slot 8, a T-block 9, an electric push rod 10, a brush plate 11, a cylinder 12, and a square block 13. The connecting plate 7 is located at the bottom of the body 1. The T-slot 8 is formed on the connecting plate 7. One end of the T-block 9 extends into the T-slot 8, and the other end of the T-block 9 is connected to one end of the electric push rod 10. The other end of the electric push rod 10 is connected to one end of the brush plate 11. One end of the block 13 is connected to the brush plate 11, and the other end of the block 13 extends into the bottom of the body 1. One end of the cylinder 12 is connected to one end of the T-block 9, and the other end of the cylinder 12 passes through the T-slot 8. A controller 14 is provided on the front of the body 1, and the controller 14 is electrically connected to the body 1.
[0023] Working principle
[0024] First, the entire equipment can be moved to the designated working position via the pulley assembly 5 at the bottom of the machine body 1. The pulley assembly 5 is equipped with a brake assembly. After the equipment is in place, the pulley is locked and fixed by the brake assembly to prevent the equipment from shifting during operation. After the equipment is fixed, the operator can start the machine body 1 to carry out the heating operation. The machine body 1 is a conventional energy-saving tunnel furnace on the market. Its internal heating structure (such as heating elements and hot air circulation system) and basic energy-saving principle are well known to those skilled in the art and will not be described in detail here.
[0025] After prolonged use, dust can easily accumulate in the gap between the machine body 1 and the ground, requiring cleaning (see reference). Figure 1 First, the staff holds the machine body 1 to maintain stability, and then starts the sliding component 3. When the sliding component 3 runs, it drives the sliding block 4 to move, so that the pulley component 5 on the sliding block 4 is off from directly below the machine body 1, so as to avoid the pulley component 5 from obstructing the subsequent cleaning operation. Then, the staff starts the electric push rod 10 at the bottom of the connecting plate 7. The electric push rod 10 extends and drives the brush plate 11 to move downward until the brush bristles at the bottom of the brush plate 11 are in full contact with the ground. At this time, the square 13 at the top of the brush plate 11 will completely separate from the preset groove on the connecting plate 7, releasing the vertical constraint of the brush plate 11.
[0026] Subsequently, the staff grasped the cylinder 12 and pulled it horizontally. The cylinder 12 caused the connected T-block 9 to slide smoothly along the T-slot 8 on the connecting plate 7 (the T-block 9 and the T-slot 8 are designed to match to ensure smooth sliding), which in turn caused the brush plate 11 to move synchronously. During the movement of the brush plate 11, the bristles at its bottom can sweep the dust under the machine body 1 to the edge of the machine body 1. Finally, the staff used a vacuum cleaner or other tools to remove the dust at the edge, thus completing the cleaning operation. The sliding component 3 mentioned in the text is a conventional transmission structure on the market, which includes components such as a slide groove, a slider, a motor, a coupling, and a threaded rod. Its specific transmission principle is a well-known technology in the field and will not be described in detail here.
[0027] To further improve the stability of the cleaning mechanism 6 during operation and prevent the brush plate 11 from shifting or shaking during the cleaning process, thus affecting the dust cleaning effect, in this embodiment, the two T-slots 8 and the two T-blocks 9 are symmetrically arranged with the central axis of the connecting plate 7 as the reference. This symmetrical design allows the T-blocks 9 to provide bidirectional balanced support to the brush plate 11 through the T-slots 8, preventing the brush plate 11 from tilting due to uneven force on one side and ensuring that the bristles always maintain uniform contact with the ground. On the other hand, it allows the T-blocks 9 to slide smoothly along the symmetrical T-slots 8 when the operator pulls the cylinder 12 to move the brush plate 11, avoiding jamming or shifting. This provides a stable structural foundation for the efficient cleaning of dust at the bottom of the machine body 1 and meets the reliability requirements for long-term use of the equipment.
[0028] To further improve the operational stability of the cleaning mechanism 6 during cleaning operations and prevent jamming or shifting due to excessive gaps in the component fit when the brush plate 11 moves, thus affecting the cleaning efficiency of the dust at the bottom of the machine body 1, this embodiment is specifically designed with a structure in which the T-slot 8 and the T-block 9 are matched. Here, "matching" not only means that the two are perfectly matched in terms of shape and cross-sectional profile, but also that the wobble space between the components is reduced by strictly controlling the fit tolerance, ensuring that the T-block 9 remains stable when sliding along the T-slot 8, and that the brush plate 11 will not tilt or shift due to gaps. This precise matching design allows the T-block 9 to provide stable guiding support for the brush plate 11. Even if the operator pulls the cylinder 12 to drive the brush plate 11 to clean back and forth, it can still ensure that the bristles at the bottom of the brush plate 11 are in uniform contact with the ground, providing a reliable structural guarantee for efficiently cleaning the dust under the machine body 1.
[0029] To further enhance the stability of the equipment during placement and movement, and to prevent the machine body 1 from tilting or shaking due to uneven distribution of the moving mechanisms 2, or even causing equipment displacement or malfunction of internal heating components, in this embodiment, several moving mechanisms 2 are symmetrically arranged with the central axis of the bottom of the machine body 1 as the reference. This symmetrical layout allows the weight of the machine body 1 to be evenly transferred to the ground through the moving mechanisms 2, preventing damage to individual moving mechanisms due to overload. At the same time, it ensures that the equipment maintains its center of gravity balance when moving with the help of the pulley assembly 5 or fixed by the brake assembly. Even if the machine body 1 carries heated workpieces and the overall weight increases, it can still maintain a stable state through the symmetrically distributed moving mechanisms. This provides a solid structural guarantee for the safety of tunnel furnace heating operations and the convenience of moving operations, and better adapts to the needs of multi-position use of equipment in industrial scenarios.
[0030] To further improve the convenience and efficiency of equipment operation and avoid the cumbersome operation or inaccurate parameter control caused by manual operation of the sliding component 3 and the electric push rod 10, in this embodiment, the controller 14 is electrically connected to the sliding component 3 and the electric push rod 10 respectively. This connection design allows operators to complete the operation without close contact with the bottom parts of the equipment, simply by using the controller 14 on the front of the machine body 1. For example, if the position of the pulley component 5 needs to be adjusted, the controller 14 can send signals to control the start, stop and operating parameters of the sliding component 3. If the brush plate 11 needs to be driven to rise and fall for cleaning, the controller 14 can also precisely control the extension and retraction stroke of the electric push rod 10. This reduces the intensity of manual operation and avoids the errors that may occur during manual operation, making the equipment movement and bottom cleaning operations more efficient and precise, and adapting to the needs of convenient operation and maintenance in industrial scenarios.
[0031] To further enhance the stability of the connection between the cleaning mechanism and the machine body, and to ensure that the connecting plate 7 can stably support the weight of cleaning components such as the electric push rod 10 and the brush plate 11 over a long period of time, thus preventing the cleaning mechanism from shifting or failing due to loose connections during cleaning operations (such as pulling the brush plate 11 back and forth for cleaning, or the electric push rod 10 for telescopic drive) or equipment movement, this embodiment specifically employs welding to connect the connecting plate 7 to the machine body 1. Compared to bolt connections, snap-fit connections, and other methods, welding allows the connecting plate 7 and the machine body 1 to form an integrated structure, effectively eliminating the connection gap between them and significantly improving the tensile and shear resistance of the connection parts. Even when faced with external forces during cleaning or vibrations during equipment movement, it can maintain a stable connection state, providing solid structural support for the efficient operation of the cleaning mechanism and precise cleaning of dust at the bottom of the machine body 1, and ensuring the overall reliability of the equipment.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
