Description

Technical Field

[0001] This utility model belongs to the field of carbon rod production technology, and in particular relates to a core rolling machine. Background Technology

[0002] Carbon rods, as an important industrial raw material, are widely used in metallurgy, power, chemical and other industries, playing a particularly important role in electrode materials and thermal power generation. With the continuous advancement of industrialization, carbon rod production technology has gradually been innovated and developed. The production process of carbon rods involves multiple stages, including raw material selection, forming, drying, and carbonization, among which the forming stage plays a crucial role in improving carbon rod quality and production efficiency.

[0003] Traditional carbon rod production processes mainly involve mixing and pressing carbonized raw materials, followed by drying and carbonization. This process typically requires manual or mechanical pressing, but due to limitations in the molding technology, it often results in unstable molding quality, uneven molding, and even defects such as cracks and deformation, thus affecting the quality of the final product. To improve molding efficiency, reduce manual operation, and improve the overall quality of carbon rods, more and more companies are seeking automated and refined production solutions.

[0004] In the existing carbon rod production process, the application of a core rolling machine is a crucial step. The core rolling machine is used to precisely roll and tumble long strips of carbon rod raw material, making its surface smoother and denser, thus ensuring the density and uniformity of the carbon rods. Traditional core rolling machines use a motor-driven belt or rollers to convey and roll the material, but this method often suffers from low efficiency, high energy consumption, and complex operation.

[0005] To improve the efficiency of core-making machines, many researchers and engineers have proposed various improvement schemes. For example, optimizing the core-making process involves adjusting the motor speed using a frequency converter and adding adjustable mechanical structures. However, existing core-making machines still have some problems. For instance, the material is easily affected by external forces during core-making, resulting in unevenness, and it is difficult to achieve precise core-making and adjustment for materials of different diameters. Furthermore, traditional core-making machines have relatively complex structures and high maintenance costs, which burden production efficiency and economic efficiency. Utility Model Content

[0007] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows:

[0008] A core-rolling machine includes a frame, on which a lower liner and a conveyor belt are provided. The conveyor belt is driven by a first motor and can slide on the upper surface of the lower liner. The frame also includes an upper liner and a pressing belt. The pressing belt extends along the length of the conveyor belt and is located on the lower surface of the upper liner and above the conveyor belt. The lower surface of the pressing belt is parallel to the upper surface of the conveyor belt and is spaced apart from the conveyor belt to form a kneading space for kneading rod-shaped materials to change their diameter.

[0009] As a further improvement to the above technical solution:

[0010] The frame is connected to a support, which is connected to the upper liner and is equipped with multiple rollers. The pressing belt is wound around each roller and can rotate through the rollers.

[0011] The support is also equipped with a second motor, which is driven and connected to one of the rollers and can drive the pressing belt to rotate.

[0012] The conveyor belt and the pressing belt move in the same direction but have a speed difference.

[0013] The frame is also equipped with an emergency stop button, which is electrically connected to the first motor and the second motor via a controller.

[0014] Protective covers are provided at the shafts of the conveyor belt, pressing belt, first motor, and second motor.

[0015] The frame is equipped with a lifting device. The top of the lifting device is connected to the support and can adjust the height of the support to change the diameter of the rod-shaped material.

[0023] To facilitate understanding of this utility model, the following description will be provided in more comprehensive and detailed manner with reference to the accompanying drawings and preferred embodiments. However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0024] Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by those skilled in the art. The technical terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the scope of protection of this invention.

[0025] Unless otherwise specified, all raw materials, reagents, instruments and equipment used in this invention can be purchased from the market or prepared by existing methods.

[0026] Example: Figure 1As shown, the core-rolling machine of this embodiment includes a frame 1, on which a lower liner plate 11 and a conveyor belt 2 are provided. The conveyor belt 2 is driven by a first motor 21 and can slide on the upper surface of the lower liner plate 11. The frame 1 also includes an upper liner plate 12 and a pressing belt 3. The pressing belt 3 extends along the length of the conveyor belt 2, is located on the lower surface of the upper liner plate 12 and above the conveyor belt 2, and its lower surface is parallel to the upper surface of the conveyor belt 2, forming a kneading space between the pressing belt 3 and the upper surface of the conveyor belt 2 to knead the rod-shaped material and change its diameter. Through the cooperative design of the lower liner plate 11 and the conveyor belt 2, stable material transmission can be achieved, and the smooth transmission of the material is ensured by driving the conveyor belt with the first motor 21. Compared with traditional core-rolling equipment, this design reduces friction and resistance during the conveying process, thereby avoiding the problems of material jamming or uneven transmission and improving the overall efficiency of the equipment. Furthermore, the configuration of the upper liner 12 and the pressing belt 3 allows for precise control of the kneading space during the kneading process, thereby effectively adjusting the diameter of the rod-shaped material. This design enables the core-rolling machine to maintain consistency and precision when processing materials of different diameters, overcoming the shortcomings of traditional equipment in material diameter control. In summary, this embodiment improves upon the problems of high friction, poor transmission, and inaccurate diameter control found in traditional equipment, making the core-rolling process more efficient, stable, and adaptable.

[0027] In this embodiment, a support 4 is connected to the frame 1. The support 4 is connected to the upper liner 12 and is equipped with multiple rollers 41. The pressing belt 3 is wound around each roller 41 and can rotate through the rollers 41. This allows the pressing belt 3 to rotate stably, reducing the uneven rotation problem that may occur with the pressing belt 3 in traditional equipment. The roller support not only improves the stability of the pressing belt 3, but also effectively reduces mechanical friction and wear, thereby increasing the service life and working efficiency of the equipment.

[0028] In this embodiment, the support 4 is also equipped with a second motor 42, which is driven by one of the rollers 41 and can drive the pressing belt 3 to rotate. This allows the pressing belt 3 to be independently and precisely controlled to rotate. The second motor 42 provides additional power support, allowing the pressing belt 3 to adjust its speed or reverse its movement as needed, thereby achieving more flexible operation and avoiding excessive pressing or uneven kneading of the material.

[0029] In this embodiment, the conveyor belt 2 and the pressing belt 3 move in the same direction but with a speed difference. By adjusting the speed difference between the two, the kneading process of the material can be precisely controlled, ensuring that the force is uniform during the processing of the rod-shaped material, enhancing the kneading effect, ensuring that the shape change of the material meets the requirements, and improving production efficiency.

[0030] In this embodiment, the frame 1 is also equipped with an emergency stop button, which is electrically connected to the first motor 21 and the second motor 42 via a controller. This ensures that the operator can quickly stop the machine in the event of an emergency, avoiding potential risks caused by mechanical failure or improper operation.

[0031] In this embodiment, protective covers are provided at the shafts of the conveyor belt 2, the pressing belt 3, the first motor 21, and the second motor 42. This effectively prevents the mechanical parts from being exposed, protects operators from injury, and enhances the safety of the equipment.

[0032] In this embodiment, a lifting device 5 is provided on the frame 1. The top of the lifting device 5 is connected to the support 4, and the height of the support 4 can be adjusted to change the diameter of the rod-shaped material. The adjustable height of the support 4 changes the kneading space of the material, adapting to the processing needs of materials with different diameters. The equipment is more flexible, can meet the processing requirements of various specifications of materials, and improves the overall efficiency of the production line.

[0033] In this embodiment, the lifting device 5 includes a lead screw 51 and two connecting rods 52. A connecting groove 53 is provided on the frame 1. The top of the lead screw 51 is connected to the support 4, and the bottom of the lead screw 51 passes through the connecting groove 53. An adjusting nut 54 is threaded onto the lead screw 51, and the adjusting nut 54 abuts against the frame 1. The two ends of the two connecting rods 52 are respectively hinged to the support 4 and the frame 1, forming a parallelogram mechanism. The parallelogram mechanism ensures stability during the adjustment process. By adjusting the adjusting nut 54, the lifting of the support 4 can be precisely controlled, ensuring the accuracy and stability of the height adjustment. This design not only improves the accuracy of the adjustment process but also reduces potential mechanical errors in the equipment, enhancing operational reliability.
