Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a grinding machine with a double support structure. Background Technology

[0002] A grinding machine is a device that uses abrasive brushes containing silicon carbide or alumina to grind the surface of materials. This grinding process significantly improves defects remaining on the surface of materials from previous processes, such as oxidation, scratches, peeling, spots, and stubborn contaminants, enhancing the consistency of surface quality. With the continuous iteration and development of science and technology, high-tech products are increasingly demanding higher quality raw materials. This presents new challenges to the quality of finished raw materials in processing plants. Therefore, in the copper processing field, the requirements for the smoothness and consistency of copper strip surfaces have reached a new level. Currently, one way to improve the surface quality of copper strips is through grinding or brushing processes. These processes generally include: 1. Belt sander treatment; 2. Wire brush treatment; 3. Nylon belt abrasive brush treatment; 4. Abrasive brush treatment. Among these, finished copper strip treatment typically uses nylon belt abrasive brush treatment and abrasive brush treatment. Modern high-precision copper strip surface treatment primarily uses abrasive brush treatment. With the continuous development of technology, the manufacturing requirements for grinding machines are also becoming increasingly stringent.

[0003] Existing grinding machines have certain drawbacks in use. Whether it's a nylon belt abrasive brush machine or an abrasive brush machine, the basic structure involves a brush roller and a back roller used in pairs. Both the brush roller and the back roller are single-supported and suspended. The advantage of this structure is its simplicity and high economy, but it also has a significant problem: it can only handle narrow and thin copper strips, and the brush's pressure cannot be too high. This results in poor versatility and is not conducive to obtaining better strip surface quality. To solve this problem or broaden its application range, a new structure needs to be proposed to optimize it. Therefore, a double-support structure is proposed, where both the brush roller and the back roller are supported at both ends. Because the rollers are supported on both sides, they can withstand greater pressure. Thus, the brush roller can withstand greater pressure, which makes the texture on the copper strip surface more uniform, and the treatment of some defects (oxidation, peeling, etc.) will be more thorough. After theoretical and experimental testing (increasing the brush pressure), the surface defects of the strip were significantly improved, and even a "wire drawing" effect was produced. The consistency of the material surface quality was fully guaranteed. Therefore, we propose a grinding machine with a double support structure. Utility Model Content

[0028] Furthermore, the brush roller shaft 5 is supported simultaneously by the first brush roller bearing seat 3 and the second brush roller bearing seat 8.

[0029] Furthermore, the back roller shaft 14 is supported simultaneously by the first back roller bearing seat 12 and the second back roller bearing seat 17.

[0030] Working principle: This utility model includes an upper fixed support 1, a servo motor 2, a first brush roller bearing seat 3, a first brush roller lifting mechanism 4, a brush roller shaft 5, a brush roller assembly 6, a second brush roller lifting mechanism 7, a second brush roller bearing seat 8, a brush roller motor 9, a support frame 10, a back roller motor 11, a first back roller bearing seat 12, a first back roller lifting cylinder 13, a back roller shaft 14, a back roller assembly 15, a second back roller lifting cylinder 16, a second back roller bearing seat 17, a lower fixed support 18, abrasive material 19, a first motor support 20, and a second motor support 21. It solves the problem of short brush life in the actual operation of cantilever structures. Furthermore, because it can increase the brush pressure, it can also solve or improve material surface defects that cannot be solved by cantilever structures to a certain extent, thereby improving the yield of finished materials. The actual test results show significant improvement.

[0031] The dual-support structure consists of five main parts: brush roller assembly, brush roller lifting assembly, back roller assembly, back roller lifting assembly, and drive assembly.

[0032] The brush roller assembly consists of a left and right brush roller bearing housing as supports, a brush roller shaft, and a brush roller, ensuring the stability of the brush's operation.

[0033] Brush roller lifting assembly: The left and right brush roller bearing seats are respectively connected to the corresponding lifting platforms. The lifting platforms are connected in series and driven by a servo motor to realize the adjustment and control of the brush pressing amount.

[0034] Back roller assembly: It consists of a left back roller bearing seat and a right back roller bearing seat as support, which realizes the reliability of back roller support and stable operation.

[0035] Back roller lifting assembly: The left and right back roller bearing seats are respectively connected to the corresponding hydraulic cylinders to realize the raising and lowering of the back roller.

[0036] Drive components: The motor is connected to the brush roller assembly and the back roller assembly respectively through couplings, so that each can operate independently.

[0037] In a double-support structure, the brush is supported on both sides, so its shape only changes with the width of the belt during use, resulting in a "dumbbell" shape. In a cantilever structure, however, the force is greater on one side and less on the other, leading to uneven deformation on both sides of the brush. This causes the brush to gradually become conical during use, resulting in a greater amount of brush wear and a reduced brush lifespan. A reduced brush lifespan means increased production costs on the production line.

[0038] In addition, the dual-support structure allows the brush to withstand greater pressure, and greater pressure means that the brush can increase the grinding "depth". This allows the grinding machine to more thoroughly remove or even completely remove surface defects of the material, such as oxide scale, blemishes, and scratches, thereby improving the surface quality of the strip.

[0039] It should be noted that, in this document, relational terms such as first and second (number one, number two), etc., are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
