Description

Technical Field

[0001] This utility model relates to the field of sintering furnace technology, specifically to a loading and unloading structure for an oxide ceramic product sintering furnace. Background Technology

[0002] Oxide ceramic sintering furnaces are key pieces of equipment specifically designed for high-temperature sintering of oxide ceramic materials (such as alumina, zirconium oxide, and magnesium oxide). By precisely controlling parameters such as temperature, atmosphere, and pressure, they densify the ceramic green body at high temperatures, forming ceramic products with specific microstructures and properties.

[0003] According to CN219674792U, a convenient box-type sintering furnace is disclosed. This technology discloses "a convenient box-type sintering furnace, belonging to the field of box-type sintering furnace technology, including a furnace wall, a furnace door hinged to the side wall of the furnace wall, a set of heat insulation layers fixedly connected to the inner wall of the furnace wall, another set of heat insulation layers fixedly connected to the side wall of the furnace door, a first sliding groove located inside the furnace wall is opened in the heat insulation layer, a sliding table is slidably connected to the inner wall of the first sliding groove, multiple sets of support feet are fixedly connected to the bottom of the furnace wall, and a door handle is fixedly connected to the side wall of the furnace door." This technology has the following technical effects: "The furnace door will remain open under the push of the spring rebound force, thereby preventing the furnace door from accidentally closing and damaging the alumina product when it is taken out of the sintering furnace. Furthermore, keeping the furnace door open also facilitates the placement of alumina products into the furnace, allowing the box-type sintering furnace to conveniently and quickly complete the work of taking out and placing alumina products, thus improving work efficiency."

[0004] The existing technology for handling and loading oxide ceramic products in sintering furnaces has the following main problems: manual handling is not only labor-intensive and inefficient, but also requires operators to be in close contact with the high-temperature furnace body, posing serious safety hazards; at the same time, traditional mechanical handling mechanisms are often complex in structure and occupy a lot of space, making it difficult to complete precise translation and flipping compound actions in a limited space, resulting in instability in the handling process and easy damage to ceramic products. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a picking and placing structure for sintering furnaces of oxide ceramic products. The drive component completes a combined translational and flipping motion to achieve automatic picking and placing of the placement component. The execution component adopts a gripping method of first penetrating and then hooking back to ensure that the hook accurately hooks the crossbar, reducing the risk of manual operation and improving positioning accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a loading and unloading structure for a sintering furnace of oxide ceramic products, comprising a sintering furnace body, wherein a placement component is provided on the sintering furnace body for supporting oxide ceramic products, and a loading and unloading mechanism is provided on the sintering furnace body for pulling the placement component out from inside the sintering furnace body, the loading and unloading mechanism comprising:

[0007] The main component is located at the bottom of the sintering furnace body and is used to support the sintering furnace body.

[0008] The drive assembly includes a slide plate mounted on the main body assembly. A guide rail is fixed to the top of the slide plate, and a slider is slidably mounted on the guide rail. A bearing seat is fixed to the top of the slider, and a shaft frame is pivotally connected to the upper end of the bearing seat. Guide wheels are rotatably mounted at both ends of the shaft frame. Guide frames are fixed to both ends of the top of the slide plate. Guide grooves are opened inside the guide frames, and the guide wheels are located inside the guide grooves. A second cylinder is installed at the rear end of the top of the slide plate and is used to drive the slider to move.

[0009] The execution component is set on the driver component and used to hook the placement component.

[0010] Preferably, the guide groove includes a transverse groove and a longitudinal groove that are interconnected inside the guide frame, and the transverse groove and the longitudinal groove are perpendicular to each other.

[0011] Preferably, the execution component includes a vertical plate fixed to the top of the shaft frame, a third cylinder installed at the front end of the vertical plate, a bracket fixed to the output end of the third cylinder, and hooks rotatably installed on both sides of the lower end of the bracket.

[0012] Preferably, the main component includes a base frame fixed to the bottom of the sintering furnace body, a balance bar fixed inside the base frame, and a sliding plate slidably mounted on the balance bar. A first cylinder is installed at the rear end inside the base frame to drive the sliding plate to move.

[0013] Preferably, the storage assembly includes a storage plate that is slidably installed inside the sintering furnace body, with an inner cavity at the front end of the storage plate and a crossbar fixed between the two ends inside the inner cavity.

[0015] Beneficial effects

[0016] This invention provides a loading and unloading structure for a sintering furnace of oxide ceramic products. Compared with the prior art, it has the following advantages:

[0017] 1. The output end of the second cylinder drives the slider to move forward along the guide rail. The slider drives the guide wheel on the shaft frame to move forward along the interior of the transverse groove through the shaft seat. When the guide wheel moves to the front end of the transverse groove, it slides to the longitudinal groove and continues to move upward. At the same time, the guide wheel drives the shaft frame to flip upward. When the guide wheel slides to the top of the interior of the longitudinal groove, it drives the actuation component to flip upward by 90° through the shaft frame, so that the actuation component is located in front of the sintering furnace body, which facilitates the pulling out of the internal placement components, reduces the risk of manual operation, and only requires a single cylinder to drive the translation and flipping combined action, reducing the complexity of the control system. When not in use, the drive component can also drive the actuation component to flip downward to the horizontal for storage and reset, avoiding the occupation of external space of the furnace body.

[0018] 2. After the upright plate is flipped upwards to a vertical position, the output end of the third cylinder drives the bracket to move the hook backwards until the hook moves between the crossbar and the inner cavity. Then, the output end of the third cylinder drives the bracket to move the hook forward slightly, so that the hook hooks the crossbar from back to front. It grabs the crossbar by first going deep and then hooking back, and the hooking back action can automatically compensate for a certain positional error. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a loading and unloading structure for a sintering furnace of oxide ceramic products, including a sintering furnace body 1, a loading assembly 3 for supporting oxide ceramic products on the sintering furnace body 1, and a loading and unloading mechanism 2 for pulling the loading assembly 3 out from inside the sintering furnace body 1. The loading and unloading mechanism 2 includes:

[0028] The main component 21 is located at the bottom of the sintering furnace body 1 and is used to support the sintering furnace body 1;

[0029] The drive assembly 22 includes a slide plate 221 mounted on the main body assembly 21. A guide rail 222 is fixed to the top of the slide plate 221. A slider 223 is slidably mounted on the guide rail 222. A bearing seat 224 is fixed to the top of the slider 223. A shaft frame 225 is pivotally connected to the upper end of the bearing seat 224. Guide wheels 226 are rotatably mounted at both ends of the shaft frame 225. Guide frames 227 are fixed to both ends of the top of the slide plate 221. A guide groove 228 is opened inside the guide frame 227, and the guide wheels 226 are located inside the guide groove 228. A second cylinder 229 is mounted at the rear end of the top of the slide plate 221 and is used to drive the slider 223 to move.

[0030] Execution component 23 is set on drive component 22 and is used to hook the placement component 3.

[0031] In this embodiment, when it is necessary to remove the storage component 3 containing the product, the output end of the second cylinder 229 drives the slider 223 to move forward along the guide rail 222. The slider 223 drives the guide wheel 226 on the shaft frame 225 to move forward along the interior of the transverse groove 2281 through the shaft seat 224. When the guide wheel 226 moves to the front end of the transverse groove 2281, the guide wheel 226 slides to the longitudinal groove 2282 and continues to move upward. At the same time, the guide wheel 226 drives the shaft frame 225 to flip upward. When the guide wheel 226 slides to the uppermost end of the interior of the longitudinal groove 2282, the guide wheel 226 drives the execution component 23 to flip upward by 90° through the shaft frame 225, so that the execution component 23 is located in front of the sintering furnace body 1, which facilitates the pulling out of the internal storage component 3 and reduces the risk of manual operation. When not in use, the drive component 22 can also drive the execution component 23 to flip downward to the horizontal for storage and reset, avoiding the occupation of external space of the furnace body.

[0032] Specifically, the guide groove 228 includes a transverse groove 2281 and a longitudinal groove 2282 that are interconnected inside the guide frame 227, and the transverse groove 2281 and the longitudinal groove 2282 are perpendicular to each other.

[0033] In this embodiment, the guide wheel 226 is forced to move along a predetermined path by the guide groove 228, ensuring the repeatability accuracy of the action of the execution component 23. Only a single cylinder is needed to drive the combined translation and flipping action, reducing the complexity of the control system.

[0034] Specifically, the execution component 23 includes a vertical plate 231 fixed to the top of the shaft bracket 225, a third cylinder 232 is installed at the front end of the vertical plate 231, a bracket 233 is fixed at the output end of the third cylinder 232, and hooks 234 are rotatably installed on both sides of the lower end of the bracket 233.

[0035] In this embodiment, when the upright plate 231 is flipped upward to vertical, the output end of the third cylinder 232 drives the bracket 233 to move the hook 234 backward until the hook 234 moves between the crossbar 33 and the inner cavity 32. Then, the output end of the third cylinder 232 drives the bracket 233 to move the hook 234 forward slightly, so that the hook 234 hooks the crossbar 33 from back to front.

[0036] Specifically, the main component 21 includes a base frame 211 fixed to the bottom of the sintering furnace body 1. A balance bar 212 is fixed inside the base frame 211, and a slide plate 221 is slidably mounted on the balance bar 212. A first cylinder 213 is installed at the rear end inside the base frame 211 and is used to drive the slide plate 221 to move.

[0037] In this embodiment, the drive assembly 22 is driven to move horizontally along the balance bar 212 by the output end of the first cylinder 213, so that the main body assembly 21 controls the execution assembly 23 through the drive assembly 22 to pull the placement assembly 3 forward from inside the sintering furnace body 1.

[0038] Specifically, the storage assembly 3 includes a storage plate 31 that is slidably installed inside the sintering furnace body 1. The storage plate 31 has an inner cavity 32 at its front end, and a crossbar 33 is fixed between the two ends inside the inner cavity 32.

[0039] In this embodiment, the inner cavity 32 ensures that the hook 234 can be quickly aligned with the crossbar 33, thereby improving operational efficiency.

[0040] Specifically, the surface of the hook 234 is provided with a high-temperature resistant ceramic coating, and the contact part of the hook 234 has an arc-shaped structure.

[0041] In this embodiment, the high-temperature resistant ceramic coating prevents the metal hook 234 from oxidizing or contaminating the oxide ceramic product at high temperatures, and the arc-shaped structure enhances the fit between the hook 234 and the crossbar 33, preventing slippage or disengagement during pulling.

[0042] The working principle and usage process of this utility model are as follows: First, when it is necessary to remove the storage component 3 containing the product, the furnace door of the sintering furnace body 1 is opened, and then the output end of the second cylinder 229 drives the slider 223 to move forward along the guide rail 222. The slider 223 drives the guide wheel 226 on the shaft frame 225 to move forward along the interior of the transverse groove 2281 through the shaft seat 224. When the guide wheel 226 moves to the front end of the transverse groove 2281, the guide wheel 226 slides to the longitudinal groove 2282 and continues to move upward. At the same time, the guide wheel 226 drives the shaft frame 225 to flip upward. When the guide wheel 226 slides to the uppermost end of the interior of the longitudinal groove 2282, the guide wheel 226 drives the execution component 23 to flip upward by 90° through the shaft frame 225, so that the execution component 23 is located in front of the sintering furnace body 1.

[0043] Then, the output end of the third cylinder 232 drives the bracket 233 to move the hook 234 backward until the hook 234 moves between the crossbar 33 and the inner cavity 32. Then, the output end of the third cylinder 232 drives the bracket 233 to move the hook 234 forward slightly, so that the hook 234 hooks the crossbar 33 from back to front.

[0044] Finally, the drive assembly 22 is driven to move horizontally along the balance bar 212 through the output end of the first cylinder 213, so that the main body assembly 21 controls the execution assembly 23 through the drive assembly 22 to pull the placement assembly 3 forward from inside the sintering furnace body 1.
