Description

Technical Field

[0001] The present invention belongs to the technical field of refractory brick production, and specifically relates to a turnover conveying device for safety protection in refractory material production. Background Art

[0002] As the core material of high-temperature industrial kilns, refractory bricks need to have high density, low porosity, and excellent thermal stability. The conveying and turnover processes in their production pose strict requirements: High brittleness and easy damage: The strength of refractory brick blanks is low before sintering, and mechanical contact is likely to cause corner cracking or surface scratches, directly affecting the qualified rate of finished products. Diverse size specifications: Different kiln requirements have given rise to products of various sizes (such as standard bricks and special-shaped bricks) and thicknesses (50 - 300 mm). Traditional equipment has poor adaptability and low production change efficiency. High-temperature pretreatment requirements: Some processes need to immediately enter the drying or pre-burning process after turnover, requiring precise and rapid posture conversion to avoid heat loss. Dust-sensitive environment: If the dust on the brick surface falls off during conveying, it may contaminate the production line or affect subsequent coating processes.

[0003] In traditional formed brick production lines, the conveying and turnover processes of refractory bricks generally have the following technical bottlenecks: Traditional conveying devices mostly use fixed baffles or rigid limiting structures, which cannot dynamically adjust the position of the bricks, and are prone to clamping misalignment due to conveying deviation, requiring frequent manual intervention for rectification, with low efficiency and poor consistency. The posture of the bricks (such as tilting and misalignment) is not pre-corrected, and when directly entering the turnover station, it is easy to cause clamping mistakes or dropping, increasing the scrap rate. Traditional turnover mechanisms mostly use rigid jaws or mechanical buckles, and the clamping force is uncontrollable, and it is easy to cause corner breakage or surface scratches of the bricks due to pressure concentration, especially significantly damaging high-brittleness refractory bricks. There is a lack of a buffering mechanism during the turnover process, and the bricks are prone to break away from the clamping due to inertial impact, posing a safety hazard. The equipment structure is fixed, and changing the brick specifications requires replacing fixtures or re-calibrating, which is time-consuming and laborious, and it is difficult to meet the production requirements of multiple varieties and small batches. The adjustment of the turnover angle and speed depends on mechanical limits or manual operations, with insufficient flexibility and difficult to meet complex process requirements. The transmission system (such as chains and gears) is easily affected by the vibration of the production line and is prone to wear during long-term operation, resulting in turnover angle deviation or jamming faults. Adsorption components such as suction cups rely on a single power source, and the bricks are prone to fall off in case of sudden power failure, causing production line interruption or equipment damage. The key transmission components are exposed, posing a risk of accidental contact by personnel; There is no emergency temporary storage station set in the turnover area, and it is difficult to intervene in time in case of a fault, affecting the continuity of the production line.

[0031] Refer to Figure 1 - Figure 6 : The driving assembly includes a driving motor 7 and a transmission 8. The transmission 8 is fixedly arranged on the outer wall of the transport table 1 through a bracket. The driving motor 7 is fixedly arranged on the outer wall of the transmission 8. The output end of the driving motor 7 is fixedly arranged on the outer wall of the input end of the transmission 8. The output end of the transmission 8 is fixedly arranged on the outer wall of the rotating frame 4.

[0032] Refer to Figure 1 - Figure 6 : One end of the guide rail 601 is triangular. An installation frame 2 is fixedly arranged on the outer wall of the transport table 1, and a plurality of rollers 201 are rotatably embedded in the inner wall of the installation frame 2. A protective shell 102 is sleeved on the outer wall of the transport table 1. A placement table 5 is fixedly arranged on one side of the outer wall of the transport table 1.

[0033] The following details the usage method of a flipping and conveying device for fireproof material production safety protection provided by an embodiment of the present invention. The usage method includes the following steps:

[0034] Refractory bricks are transported to the rollers 201 of the mounting frame 2 through the upstream process. The rollers 201 rotate with the conveyor belt 101, and smoothly transport the brick bodies to the surface of the conveyor belt 101 of the transport table 1. The mounting frame 2 and the rollers 201 provide a continuous brick supply function, ensuring that the brick bodies are evenly distributed and avoiding accumulation. The conveyor belt 101 transports the brick bodies to the sorting component area at a constant speed. When the brick bodies enter the sorting area, the lifting cylinder 302 drives the lifting plate 303 to descend, and contacts the surface of the brick bodies through the rubber pad 305. At the same time, the resistance-reducing wheel 304 slides along the guide rail 601 to adjust the horizontal position of the lifting plate 303. The blocking wheel 306 and the resistance-reducing wheel 304 cooperate to limit the left-right offset of the brick bodies, ensuring that the center line of the brick bodies is aligned with the conveying direction. The triangular end design of the guide rail 601 guides the smooth movement of the lifting plate 303, reducing the frictional resistance. If the specifications of the brick bodies change, the adjustment frame 6 adjusts the spacing of the guide rail 601 through bolts to adapt to brick bodies of different sizes. The brick bodies after deviation correction are continuously transported to the flipping station. The clamping cylinder 403 is activated, driving the driving frame 404 to move towards the brick bodies along the slide rail 402. The suction cup 409 adsorbs the surface of the brick bodies through an external negative pressure system. The convex structure of the mounting ring 408 and the limiting frame 407 limits the displacement of the brick bodies. The buffer spring 406 is compressed and contracted to dynamically compensate for the thickness error of the brick bodies, avoiding clamping overload. The linkage rod 9 is inserted into the linkage hole 405 of the driving frame 404 to ensure the synchronous action of multiple clamping points and the uniform distribution of the clamping force. The driving motor 7 outputs a set rotation speed through the transmission 8, driving the rotating frame 4 to rotate 90° around the shaft seat 401, turning the brick bodies from a lying state to a standing state. The transmission 8 adjusts the flipping speed to ensure a smooth posture conversion and avoid inertial sliding of the brick bodies. The double-support structure of the slide rail 402 and the shaft seat 401 disperses the rotation torque, improving the stability. The negative pressure adsorption of the suction cup 409 still maintains a short-term adsorption when the power is cut off, preventing the accidental detachment of the brick bodies. After flipping is completed, the clamping cylinder 403 resets, and the suction cup 409 releases the negative pressure. The brick bodies fall onto the placement table 5 or directly enter the downstream process (such as stacking and drying). The brick bodies in the standing state do not require secondary positioning and can be directly adapted to subsequent automated equipment. The protective shell 102 covers the transmission components to prevent accidental contact by personnel. The placement table 5 serves as a temporary transfer area, supporting emergency temporary storage during manual intervention. The flipping component resets to the initial position, the lifting plate 303 of the sorting component is lifted, and the conveyor belt 101 continues to transport the next brick body, and the above process is executed cyclically. The double buffering of the resistance-reducing wheel 304 and the buffer spring 406 absorbs the vibration of the production line, reducing the risk of shutdown. The modular design simplifies maintenance and specification switching.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
