Description

Technical Field

[0001] This utility model belongs to the field of graphene sagger technology, and in particular relates to a graphene sagger core-removing machine. Background Technology

[0002] Graphite saggers, widely used in high-temperature containers in metallurgy, chemical industry, and other sectors, directly impact production efficiency and product quality due to the integrity of their internal structure. In high-temperature industrial applications, graphite saggers serve as critical load-bearing containers, and their internal structural design directly influences production efficiency and product quality. Core-shaving, a core step in graphite sagger manufacturing, effectively solves problems such as uneven heat conduction and material stress concentration inherent in traditional designs by precisely controlling the internal spatial structure. This technological innovation not only improves the mechanical strength and service life of the sagger but also significantly improves the thermal efficiency distribution under high-temperature environments by optimizing internal airflow channels. Practice shows that graphite saggers treated with scientific core-shaving can improve temperature uniformity by more than 30% while reducing energy consumption by approximately 15%. This functional and economical technological improvement has become an important direction for upgrading modern high-temperature industrial equipment.

[0003] Comparing with Chinese Patent CN216578598U, a graphite sagger core-removing machine is disclosed, including a base plate, a machine body fixedly connected to the base plate, a main transmission mechanism on the top of the machine body, an eccentric disc movably connected to the left side of the main transmission mechanism, a connecting rod movably connected to the upper part of the eccentric disc, a sliding plate connected to the right side of the connecting rod, two support rod seats on the sliding plate, and a support rod movably connected to the middle of the support rod seats. By setting up the transmission mechanism, the eccentric disc can be controlled to move back and forth, causing the eccentric disc to drive the support rod seats to move back and forth through the machine base. The back and forth movement of the support rod seats causes the feed mechanism to move up and down, performing reciprocating cutting on the workpiece. This achieves the effect of facilitating operation for workers and improving processing efficiency, solving the problems of large processing area, long processing time, high dust levels, significant material waste, and inconvenience for one person operating multiple machines in existing graphite sagger processing processes.

[0004] However, the aforementioned patent can only remove the core from the graphite sagger from the top and bottom, making it difficult to guarantee the flatness of the bottom surface of the graphite sagger and resulting in poor product consistency; therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a graphite sagger core-removing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A graphite sagger core-removing machine includes a main unit for core removal from graphite saggers, and a feeding device for vertical movement and lifting at one end of the main unit. The feeding device is equipped with a positioning device for clamping, centering, and rotating the graphite sagger from four sides. The main unit includes a main body with a sliding plate frame slidably mounted on it. A drive assembly for providing reciprocating power is located on one side of the sliding plate frame. Two support rod fixing seats are symmetrically arranged on the sliding plate frame, and a support rod body is movably mounted in the middle of each support rod fixing seat. The feeding device includes a column frame with a lead screw mounted in the middle. A second motor is located at the top of the lead screw, and a lifting assembly is mounted in the middle of the lead screw. The positioning device includes a rotating frame with four cantilever frames evenly distributed on its four sides. Telescopic cylinders are mounted on the cantilever frames, and fixed clamps are mounted on the telescopic ends of the telescopic cylinders. A shifting assembly is located on the side of the rotating frame away from the cantilever frames.

[0008] Furthermore, the drive assembly includes a first motor, an eccentric wheel is mounted on the output end of the first motor, a movable connecting rod is mounted on the eccentric wheel, and the movable connecting rod is rotatably connected to the eccentric wheel and the slide frame respectively.

[0009] Furthermore, an adjusting element for adjusting the tension of the saw blade is provided between the two support rod fixing seats.

[0010] Furthermore: the lifting assembly includes a screw sleeve slider installed in the middle of the lead screw, and a lifting frame is provided in front of the screw sleeve slider, the lifting frame being frame-shaped.

[0011] Furthermore: the shifting assembly includes a drive shaft located at the center of the rotating frame, a third motor located at the end of the drive shaft, the third motor being installed inside the lifting frame, and the drive shaft passing through the lifting frame and connecting to the rotating frame.

[0012] Furthermore: the rotating frame is square, and the cantilever frame and the rotating frame are welded together.

[0013] Furthermore, the fixing clamp is rectangular, and the clamping surface is covered with an anti-slip pad.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. The drive component drives the saw blade to reciprocate to achieve efficient core removal. Combined with the 90-degree rotation function of the rotating frame, the bottom surface of the sagger can be cored a second time to ensure the flatness of the bottom surface and avoid the problems of low efficiency and poor flatness of traditional manual operation.

[0016] 2. The positioning device uses a four-sided synchronous telescopic cylinder to drive the fixed clamping plate, realizing automatic centering and stable clamping of the graphite sagger. The anti-slip rubber pad on the surface of the clamping plate further prevents slippage, ensuring the positioning accuracy and safety of the core removal process.

[0017] 3. The main unit, feeding device and positioning device work together to form an automated process of core removal-feeding-positioning, which significantly reduces the need for manual intervention and improves production efficiency. It is especially suitable for batch processing of graphite saggers. While improving core removal efficiency, accuracy and product consistency, it reduces labor intensity and production costs, and is suitable for large-scale processing of graphite saggers.

[0018] 4. The design of the square rotating frame and the four-sided cantilever frame supports the clamping requirements of different sized crucibles. By adjusting the cylinder stroke or the position of the clamping plate, it can be adapted to various specifications, enhancing the versatility of the equipment. Attached Figure Description

When core removal, the main body 101 supports the first motor 102 to drive the eccentric wheel 103 to rotate, and pushes the slide frame 105 to move back and forth through the movable connecting rod 104, which drives the support rod fixing seat 106 and the support rod body 107 to move back and forth, and the saw blade between the support rod bodies 107 removes the core from the graphite crucible.
