- 1. Technical Field
- The present disclosure relates to a tip holder integrated with polishing tips that is attachable to a tip holder plate of a concrete polishing machine.
- 2. Description of the Related Art
- Generally, to polish a concrete surface C clean and smooth, a
concrete polishing machine 1 having a plurality oftip holders 10 bonded withpolishing tips 20 ontip holder plate 3 at a certain intervals is used. The polishing work is conducted by rotating thetip holder plate 3, which in turn rotates thetip holder 10 andpolishing tips 20 to grind the concrete surface C. - However, the
conventional tip holder 10 shown inFIG. 1 , which is provided withpolishing tips 20 at certain intervals, has disadvantages. For example, with reference toFIG. 1 , hollow tip supports 11 in which thepolishing tips 20 are coupled are formed protrusively at certain intervals on the bottom circumference and thepolishing tips 20 andtip holder 10 are formed as independent members, thetip holder 10 and the hollow tip supports being injection molded with a plastic resin having weak resistance to heat, such as nylon, PE, PP, or ABS, and their function is simply hold and support thepolishing tips 20. As such, the tip supports 11 of thetip holder 10 cannot polish a concrete surface C together with thepolishing tips 20, when thepolishing tips 20 have been worn down. - In addition, when polishing a concrete surface C using the
polishing tips 20 attached to thetip holder 10 made of a plastic material, for example, nylon, PE, PP or ABS, which have weak resistance to heat, as shown inFIG. 2 a andFIG. 2 b, the bottom of thepolishing tips 20, that is, thepolishing tips 20 protruding out of the tip supports 11 of thetip holder 10 is worn down to the end by friction with the concrete surface C. At this condition, by the heat generated by the friction between the end of thetip holder 10, that is the tip supports 11 andpolishing tips 20 and between the concrete surface C, the end of the tip supports 11 of thetip holder 10, made of a plastic material having a weak resistance to heat, melts down and leaves swirling marks with the molten resin from thetip support 11 of thetip holder 10 on the concrete surface C. - Furthermore, when the swirling marks are formed on the concrete surface C by the end of the tip supports 11 of the
tip holder 10, made of a plastic resin having weak resistance to heat, for example, nylon, PE, PP, or ABS and molten into a ball-shape, by the heat generated from grinding the concrete surface C together with thepolishing tips 20, extra polishing work is required to remove the swirling marks from the concrete surface C. - Embodiments of the present invention provide a tip holder, and more particularly, a tip holder, integrated with polishing tips, which is attachable to a tip holder plate of a concrete polishing machine. To replace conventional tip holders, which are made of the plastic materials having weak resistance to heat, such as nylon, PE, PP, ABS, etc., and installed with separate polishing tips in tip holes thereof, the tip holder is compression molded with a heat-resistant material with integrated polishing tips. Beneficially, the ends of tip supports of the tip holder are well adapted to not melt by heat generated during polishing, but rather pulverize and polish the concrete surface together with the polishing tips, preventing the swirling marks otherwise formed on a concrete surface by the tip holders of conventional systems, which become molten when the polishing tips are worn down. In addition, another benefit of embodiments of the present invention is that the compression molded tip holder with integrated polishing tips can help polish the concrete surface as an assistant polishing means, improving the polishing performance and extending the lifecycle of the polishing tips.
- According to embodiments of the present invention, the tip holder is made of a plastic material and installable on a tip holder plate of a concrete polishing machine to polish concrete surfaces with polishing tips which are inserted and bonded with the tip holder, in a manner that the polishing tips protruding from the tip holder are ground while polishing the concrete surface together with the tip holder, so that the scratch of plastic swirl marks otherwise left on the surface by the tip holder and polishing tips can be prevented. In some embodiments, the tip holder is characterized by being made of melamine resin or phenol resin, or in another example embodiment, a mixture of 55% of phenol resin, 23% of silicon carbide (SiC), 11% of carbon (C), and 11% of talc.
- To reiterate, embodiments of the present invention provide a tip holder integrated with polishing tips and made of a heat resistant material by compression molding. Beneficially, the ends of the tip supports of the tip holder are well adapted to not melt by heat generated during polishing, but rather pulverize and polish the concrete surface together with the polishing tips, preventing the swirling marks which can otherwise be formed on the concrete surface when polishing with conventional polishing machines. In addition, the compression molded tip holder with integrated polishing tips can help polish the concrete surface as an assistant polishing means, improving the polishing performance and extending the lifecycle of the polishing tips.

holder socket 30 may be provided with a piece of Velcrotape 35 to bond thetip holder 10 a to another piece of Velcrotape 5 provided on the bottom of thetip holder plate 3 of theconcrete polishing machine 1. - As described above, the
tip holder 10 a, compression molded to enable thepolishing tips 20 to be supported and fixed in the tip supports 11, is configured such that the ends of the tip supports 11 of thetip holder 10 a do not melt down by heat generated during polishing operation, but rather pulverize and polish the concrete surface C together with thepolishing tips 20, since they are made of a heat resistance plastic material, for example, 100% of melamine or phenol resin, or a composition of melamine or phenol resin added with, for example, silicon carbide (SiC), carbon (C), and talc as additives for improving the strength and polishing performance of the polishing tips. For example, in one particular embodiment, the material may be 55% of melamine or phenol resin, 23% of silicon carbide (SiC), 11% of carbon (C), and 11% of talc. - In addition, the
polishing tips 20 which are formed as an integrated body in the tip supports 11 of thetip holder 10 a, are molded in the tip supports 11 of thetip holder 10 a and fixed on thetip holder plate 3 of aconcrete polishing machine 1 and rotated to polish concrete surfaces C. The polishing tips may be formed in a cylindrical body having a convex bottom, and may be comprised of phenol or epoxy resin, silicon carbide (SiC), artificial diamond, tin oxide (SnO2), carbon (C), and Chromium (Cr) 203. An exemplary constitution is 44% of phenol or epoxy resin, 22% of silicon carbide (SiC), 11% of artificial diamond, 11% of tin oxide (SnO2), 6% of carbon (C), and 6% of Chromium 203 (Cr). - With the
