Description

Technical field

[0001] The invention relates to the field of grinding tools, in particular to a helical tooth segmented tooth type roller. [Background Technology]

[0002] Artificial stone is a new composite material composed of natural gravel, quartz sand, resin, fillers, and curing agents. Compared to traditional building materials like natural stone and ceramic tiles, artificial stone boasts diverse functions and a rich variety of colors. It also boasts advantages such as being non-toxic, non-radioactive, flame-retardant, oil-free, antibacterial, mildew-resistant, wear-resistant, impact-resistant, high-gloss, easy to maintain, and seamless. This makes it a widely used material, particularly in kitchen countertops. The rapid growth of the artificial stone industry in recent years has naturally driven the development of artificial stone processing tools and equipment, with processing methods increasingly becoming mechanized, automated, and intelligent.

[0003] Most of the processing tools currently on the market use the existing roller structure of granite or ceramic tiles. However, due to the difference in properties between artificial stone and granite or ceramic tiles, this type of roller has problems such as poor sharpness, low processing efficiency, poor wear resistance, and short life in the actual use of artificial stone thickness determination. To address the aforementioned issues with existing roller structures, a Chinese utility model patent application, filed on March 14, 2019, with application number 201920321685.8, discloses a novel saw blade roller. The saw blade roller comprises a base rod and a plurality of grinding wheel bases, each of which comprises a base ring and a plurality of grinding heads connected to the rim of the base ring. The grinding wheel bases are closely spaced and nested on the base rod. The grinding wheel bases and the grinding heads thereon are arranged in a one-to-one correspondence and gradually staggered arrangement, forming a plurality of groups of stepped grinding elements. The unique structural design of the saw blade roller provides a structural foundation for high-performance grinding, effectively overcoming the problems of poor sharpness, low processing efficiency, poor wear resistance, and short life in the prior art. However, the saw blade roller suffers from the following problems in actual use: 1. Sharpness remains relatively poor, stability is poor, and the stepped grinding elements make chip removal inconvenient; 2. The structure is complex, manufacturing is difficult, and the cost is high. [Summary of the invention]

[0004] The technical problem to be solved by the present invention is to provide a helical tooth segmented tooth roller to solve the problems of the existing saw blade roller, such as poor sharpness, inconvenient chip removal and poor stability in use.

[0005] The present invention is implemented as follows: a helical tooth segmented tooth roller includes a roller base and a plurality of grinding components; the plurality of grinding components are continuously arranged in an annular manner on the outer wall surface of the roller base, and the axial ends of the plurality of grinding components are arranged flush; the grinding components include an axially arranged helical tooth cutter head and a chip removal groove arranged on one side of the helical tooth cutter head.

[0006] Furthermore, the two axial ends of the grinding component are parallel to each other, and the connecting line between the starting point of the end line of one axial end of the grinding component and the end point of the end line of the other axial end is perpendicular to the end lines of the two axial ends.

[0007] Furthermore, the side surface of one side of the helical tooth cutter head is a concave arc surface, and the side surface of the other side is a convex arc surface; the concave arc surface and the convex arc surface between two adjacent helical tooth cutter heads constitute the chip removal groove.

[0008] Furthermore, the inward curvature of the concave arc surface is the same as the outward curvature of the convex arc surface.

[0009] Furthermore, the polished surface of the helical tooth cutter head is an arc surface.

[0010] Furthermore, the two axial ends of the helical cutter head are planes parallel to each other.

[0011] Furthermore, a circular arc convex ring for connecting the helical tooth cutter head is provided on the middle part of the outer wall surface of the roller base.

[0012] Furthermore, the axial height of the arc convex ring is equal to the axial height of the helical tooth cutter head.

[0013] Furthermore, the connecting surface of the helical tooth cutter head is an arc surface, and the radius of the arc surface is equal to half of the outer diameter of the arc convex ring.

[0014] Furthermore, a connecting end surface is provided inwardly on the inner edge of one end of the roller base.

[0015] The advantages of the present invention are:

[0016] 1. The segmented-tooth roller of the present invention can well balance the sharpness of the cutter head and the stability of use. Specifically, the cutter head on the roller is designed as a segmented-tooth helical cutter head, and each helical cutter head has a chip removal groove on one side. The combination of the two designs improves the sharpness of the entire cutter head; at the same time, the helical cutter heads are arranged in a special arrangement so that the effective area of the cutter head in any cross section along the axial direction is consistent, thereby ensuring stability in use.

[0017] 2. The chip groove is composed of concave and convex arc surfaces, so that the rotational force of the toothed roller can be well utilized during the working process to throw the water and chips in the chip groove out from one end of the chip groove in time. Therefore, this design can improve the chip removal effect and ensure the sharpness of the cutter head.

[0018] 3. During manufacturing, the roller base can be formed by integral casting, that is, only one mold needs to be made for casting the roller base. Therefore, compared with the existing saw blade roller, the toothed roller of the present invention has a simple structure, low manufacturing difficulty and low manufacturing cost.

[Specific implementation method]

[0030] The embodiment of the present invention solves the technical problems of the existing saw blade type roller, such as poor sharpness, poor stability in use, and inconvenient chip removal, by providing a helical tooth segmented tooth roller, thereby achieving the technical effect of taking into account both the sharpness of the cutter head and the stability of use.

[0031] The technical solution in the embodiment of the present invention is to solve the above problems. The overall idea is as follows: the cutter head on the drum is designed as a split-tooth helical cutter head, and each helical cutter head has a chip groove on one side. The combination of the two designs improves the sharpness of the entire cutter head; at the same time, the helical cutter heads are arranged in a special arrangement so that the effective area of the cutter head in any cross section along the axial direction is consistent, ensuring smooth use.

[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] See also Figures 1 to 8 As shown, a preferred embodiment of a helical tooth segmented gear roller 100 of the present invention, the segmented gear roller 100 includes a roller base 1 and a plurality of grinding components 2. The roller base 1 can be made of aluminum or iron.

[0034] The grinding elements 2 are continuously arranged around the outer wall of the drum base 1. This continuous arrangement means that the grinding elements 2 are arranged one after another in an uninterrupted manner around the outer wall of the drum base 1. The axial ends of the grinding elements 2 are aligned to ensure continuous grinding and polishing of the product surface during operation. The grinding elements 2 include an axially arranged helical cutter head 21 and a chip removal groove 22 provided on one side of the helical cutter head 21. The helical cutter head 21 is specifically made of diamond.

[0035] The present invention adopts a split-tooth helical cutter head 21 design with a small force-bearing area, and a chip groove 22 is provided on one side of each helical cutter head 21 to facilitate water and chip removal. Therefore, the combined design of the split-tooth helical cutter head 21 and the chip groove 22 of the present invention is conducive to improving the sharpness of the entire cutter head, thereby improving processing efficiency.

[0036] In the present invention, the two axial ends of the grinding component 2 are parallel to each other, and the connecting line between the starting point of the end line of one axial end and the end point of the end line of the other axial end of the grinding component 2 is perpendicular to the end lines of the two axial ends. Since the grinding component 2 includes a beveled cutter head 21 and a chip groove 22 provided on one side of the beveled cutter head 21, in other words, for any grinding component 2, the connecting line between the starting point of the beveled cutter head 21 at one axial end and the end point of the chip groove 22 at the other axial end will be perpendicular to the end lines of the two axial ends of the grinding component 2. Through the special arrangement of the beveled cutter heads 21 of the present invention, it can be effectively guaranteed that the effective area of the cutter heads is consistent in any cross section along the axial direction, thereby ensuring that the force area of the product surface is always consistent during operation. Therefore, the toothed roller 100 is more stable during use and will not experience the "cutter jumping" phenomenon.

[0037] In the present invention, the side surface of one side of the helical tooth cutter head 21 is a concave arc surface 211, and the side surface of the other side is a convex arc surface 212; the concave arc surface 211 and the convex arc surface 212 between two adjacent helical tooth cutter heads 21 constitute the chip removal groove 22. Because the segmented tooth drum 100 rotates rapidly during operation, the use of the concave arc surface 211 and the convex arc surface 212 to form the chip removal groove 22 allows the rotational force of the segmented tooth drum 100 to be effectively utilized during operation, and water and chips in the chip removal groove 22 are promptly ejected from one end of the chip removal groove 22. Therefore, this design can improve the chip removal effect and ensure the sharpness of the cutter head.

[0038] In the present invention, in order to ensure that the radial distance of the chip groove 22 is consistent, and thus effectively ensure that the effective area of any cross-section of the cutter head along the axial direction is consistent, the concave curvature of the concave surface 211 is the same as the convex curvature of the convex surface 212.

[0039] In the present invention, in order to ensure the grinding effect, the grinding surface 213 of the helical cutter head 21 is an arc surface.

[0040] In the present invention, the two axial ends of the helical cutter head 21 are parallel planes 214. By designing the two axial ends of the helical cutter head 21 as parallel planes 214, on the one hand, it can effectively ensure that the effective area of the cutter head is consistent in any cross section along the axial direction, and on the other hand, it can save materials and reduce costs.

[0041] In the present invention, an arc-shaped convex ring 11 is provided in the middle of the outer wall of the drum base 1 for connecting the helical-toothed cutter head 21. In practice, the helical-toothed cutter head 21 is welded to the outer wall of the drum base 1. The design of the arc-shaped convex ring 11 not only facilitates the welding operation but also facilitates the alignment of the axial ends of the grinding components 2.

[0042] In the present invention, in order to facilitate the alignment of the grinding components 2 , the axial height of the arc convex ring 11 is equal to the axial height of the helical tooth cutter head 21 .

[0043] In the present invention, the connecting surface 215 of the helical cutter head 21 is an arc surface, and the radius of the arc surface is equal to half the outer diameter of the arc convex ring 11. By designing the radius of the arc surface equal to half the outer diameter of the arc convex ring 11, it is ensured that the connecting surface 215 of the helical cutter head 21 can completely fit the outer surface of the arc convex ring 11, thereby ensuring the security of the connection and ensuring that the polished surface 213 of each helical cutter head 21 is flush.

[0044] In the present invention, in order to facilitate the connection between the toothed roller 100 and other mechanisms (not shown), a connecting end surface 12 is provided inwardly on the inner edge of one end of the roller base 1 .

[0045] During the manufacture of the toothed roller 100 of the present invention, the roller base 1 can be formed by integral casting, that is, only one mold needs to be made for casting the roller base 1. Therefore, compared with the existing saw blade roller, the toothed roller 100 of the present invention has a simple structure, low manufacturing difficulty and low manufacturing cost.

[0046] The production process for artificial stone slabs is as follows: batching → mixing → high-pressure vibration → heating and curing → slabs → rough grinding → trimming and sizing → fine grinding → polishing → semi-finished product. The segmented toothed roller 100, a preferred embodiment of this invention, is used in the rough grinding (thickness sizing) process for artificial stone slabs. This rough grinding eliminates large surface irregularities, ensuring a consistent thickness and slab size, and preparing for fine grinding with metal cloth.

[0047] Although the specific embodiments of the present invention are described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included within the scope of protection of the claims of the present invention.
