Description

Technical Field

[0001] The utility model relates to the technical field of stone processing, in particular to a stone ball grinding production line. Background Art

[0002] The rough stone blocks mined from the mountains are processed into building materials after cutting, grinding, chiseling and polishing. These building materials are widely used in engineering construction, including round stone balls. These round stone balls can not only be used for scenery, but also as isolation piers or road piers, especially suitable for squares, parks and parking lots.

[0003] At present, the processing of round stone balls mainly adopts manual chiseling, grinding and polishing. This manual method not only has relatively high labor intensity, slow speed, small quantity, low efficiency and high labor cost, but also has uneven quality of processed round stone balls, especially diameter difference and spherical curvature difference. With the continuous rise of labor cost and the continuous development of automation technology, automatic grinding and polishing machines are usually used in existing stone production to grind and polish stones. However, most of the grinding machines are single-station and can only process one stone at a time. The grinding and polishing process usually requires multiple grinding processes from coarse to fine, and the grinding disc needs to be replaced. When replacing, it is often necessary to manually disassemble the original grinding head and then install a new grinding head. Moreover, multiple stones cannot be processed at the same time, resulting in slow processing efficiency.

[0004] In view of this, the inventor of this case conducted in-depth research on the above-mentioned issues, which resulted in this case. Utility Model Content

DETAILED DESCRIPTION

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Reference Figures 1 to 5

[0023] A stone ball grinding production line includes a central controller (not shown in the figure), an annular guide rail 1, a plurality of positioning devices 2 arranged on the annular guide rail 1 at equal intervals, a stone ball device 3 arranged on the corresponding positioning device 2, and a grinding device 4 for grinding and trimming the surface of the stone ball 5. The annular guide rail 1 is a continuous and closed annular guide rail 1, and the positioning device 2 is movably arranged on the annular guide rail 1.

[0024] Driving wheels 11 are provided at both ends of the circular guide rail 1, and driving belts 12 are wound around the two driving wheels 11. The driving wheels 11 drive the driving belts 12 to rotate. The driving belts 12 rotate and drive the driving member 13 installed on the upper side of the driving belts 12 to move. The driving member 13 extends upward and is fixedly connected to the positioning device 2 to drive the positioning device 2 to rotate the circular guide rail 1 to the work station to be processed. The driving belt 12 is located inside the circular guide rail 1. According to actual needs, several workstations 6 can be installed on both sides of the circular guide rail 1, and each workstation 6 is set to a different working area to complete different degrees of grinding of the stone ball 5, such as rough processing, fine processing, polishing and other processing procedures.

[0025] The inner and outer surfaces of the annular guide rail 1 are provided with annular guide grooves 14. The upper surface of the annular guide rail 1 is evenly spaced and slidably connected with the positioning device 2. The lower surface of the positioning device 2 is symmetrically distributed and fixedly connected with the driving member 13. By fixing the stone ball device 3 with the stone ball 5 on the driving member 13, and then conveying the stone ball 5 intermittently and uniformly on the outer surface of the annular guide rail 1 through the driving member 13, the production and processing of the stone ball 5 can be realized. By setting the annular guide rail 1, the stone ball 5 above the driving member 13 can be conveyed in an annular manner during the annular conveying process to complete the processing of its surface, thereby avoiding the manual transfer of the stone ball 5 and greatly reducing its production efficiency.

[0026] The workstation 6 includes a workbench 61, a card reader (not shown in the figure), and a driving device for pushing the grinding device 4 to approach or move away from the stone ball 5. The grinding device 4 is arranged on the workbench 61, and the card reader is located at the front end of the workstation 6. The end of the positioning device 2 facing the card reader is provided with a sensor 21 electrically connected to the card reader. The sensor 21 and the card reader are both connected to the central controller signal. The card reader and the sensor 21 can read the information of the stone ball 5 and can be used for counting. The circular guide rail 1 drives a plurality of grinding and positioning devices 2 to rotate in a circular manner, and the grinding device 4 completes the grinding and trimming of the stone ball 5 during the rotation process.

[0027] Furthermore, the grinding device 4 includes a suspension 41, a guide rail 42, a transverse cylinder 43, a water spray head 44 with a water pipe, an arc-shaped grinding disc 45 and a diamond bit 46. A workbench 61 is correspondingly configured with a suspension 41 and a transverse cylinder 43. The workbench 61 is provided with a guide rail 42 for placing the suspension 41. The suspension 41 is movably mounted on the guide rail 42 by being pushed by the transverse cylinder 43, so that the suspension 41 with the diamond bit 46 is pushed toward or away from one side of the annular guide rail 1, so that the diamond bit 46 is attached to the surface of the stone ball 5 and ground.

[0028] Furthermore, a water spray head 44 with a water pipe is arranged above the suspension 41 and facing the stone ball 5, and is used to clean the dust of the stone ball 5 during grinding or to cool the stone ball 5 during grinding. The side of the suspension 41 facing the stone ball 5 is made into an arc-shaped depression and can touch the spherical surface of the stone ball 5. The arc-shaped grinding disc 45 is arranged in the arc-shaped depression of the suspension 41, and a plurality of diamond bits 46 are arranged on the surface of the arc-shaped grinding disc 45.

[0029] Furthermore, the diamond bit 46 includes a first side 461 and a second side 462, both of which are in a concave-convex wave shape, and the concave-convex wave shape is composed of a plurality of wave crests and wave troughs alternatingly, that is, the first side 461 includes a first wave crest 4611 and a first wave trough 4612, and the second side 462 includes a second wave crest 4621 and a second wave trough 4622, the second wave crest 4621 is arranged opposite to the first wave crest 4611, and the second wave trough 4622 is arranged opposite to the first wave trough 4612. When the diamond bit 46 is unfolded, the width along the vertical direction is the same everywhere.

[0030] like Figure 5 As shown, the height (i.e. Figure 5 The position of the middle line segment b) is located at the height (i.e. Figure 5 The position of the midline segment a) is below the first wave valley 4612 of the first side wall 461, so that the first wave valley 4612 of the first side wall 461 always falls between the two adjacent second wave peaks 4621 of the second side edge 462, avoiding the appearance of annular lines on the surface of the stone ball 5 during polishing, achieving a non-polished discontinuity on the surface of the stone ball 5, optimizing the product appearance, and improving the aesthetics of the stone ball 5.

[0031] Further, the second side 462 of the diamond bit 46 disposed at the top completely overlaps with the first side 461 of another diamond bit 46 disposed at the bottom, and is tightly matched, so as to be disposed on the arc-shaped grinding disc 45 by means of threads, snaps or bonding, and each diamond bit 46 is pressed against each other. When the diamond bit 46 is unfolded, the cross section along the vertical direction is a parallelogram structure, and two adjacent diamond bits 46 can be stacked together, connected to each other and closed along the side. Specifically, the first side 461 and the second side 462 are both provided with overlapping bevels (a first overlapping bevel 4613 and a second overlapping bevel 4623), the bevel angle of the first overlapping bevel 4613 is 45 degrees, and the bevel angle of the second overlapping bevel 4623 is -45 degrees. The second overlapping bevel 4623 can perfectly match with the first overlapping bevel 4613 of the adjacent diamond bit. After the diamond bit 46 is positioned and installed with the arc grinding disc 45, it is fixed by bolts. Each diamond bit 46 is locked with the arc grinding disc 45, which is not easy to swing or detach, so as to achieve the effect of overall stability. By setting the concave and convex wavy diamond bit 46, it is avoided that annular lines appear on the surface of the stone ball 5 during grinding; at the same time, each diamond bit 46 is connected with the arc grinding disc 45 by connecting bolts or bonding, and there is no need to frequently replace the arc grinding disc 45, and the cost is relatively low; in addition, the first side edge 461 and the second side edge 462 of the overlapping bevel are provided, so that the adjacent two diamond bits 46 overlap each other, so that each diamond bit 46 is locked with the arc grinding disc 45, which is not easy to swing or detach, so as to achieve the effect of overall stability. The utility model has a simple and reasonable structure, high strength, uniform force, convenient installation, strong stability and long service life.

[0032] Furthermore, the thickness of the diamond bit 46 is 2-10 mm.

[0033] Furthermore, the positioning device 2 is fixedly set on the annular guide rail 1, and the stone ball device 3 includes a placing table 33, a first roller 31 and at least two second rollers 32 arranged on the placing table 33, and a rotating disk 34 rotatably installed on the placing table 33. The first roller 31 and each second roller 32 are respectively rotatably installed on the placing table 33, and the first roller 31 is slidably installed on the placing table 33 in a direction approaching or away from the rotating disk 34. When the grinding equipment is in working state, the first roller 31 and each second roller 32 are both in contact with the lower part of the stone ball 5, and the first roller 31 and each second roller 32 are respectively arranged around the axis of the rotating disk 34.

[0034] Furthermore, an identifiable device (not shown in the figure) is provided on the stone ball 5, and coded information of the product model and process flow is written in the identifiable device.

[0035] By adopting the above-mentioned design scheme, the beneficial effects of the utility model are: by using mechanical processing to perform polishing treatment on the stone ball 5 in multiple steps, it is possible to monitor the working status, operating position, name and number of the automatic conveying device, which is beneficial to the information of the stone ball 5 production line and coordinate the production progress between the workstations 6. The utility model has the characteristics of novel structure, fast processing speed, large processing quantity, high work efficiency, low cost, and uniform and stable processing quality.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
