DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-3 As shown, a granite arc grinding device comprises a transmission frame 1, a plurality of transmission rollers 2 are installed at the upper position of the transmission frame 1 through roller rotation, and a grinding assembly 3 is arranged at the center position of the transmission frame 1;

[0024] The grinding assembly 3 has a plurality of fixed rods 4, which are respectively installed on both sides of the interior of the transmission frame 1, and a plurality of fixed rods 4 on the same side form a group. Two driving cylinders 13 are installed at the lower position on one side of the transmission frame 1, and the end of the driving shaft of one driving cylinder 13 is fixedly connected with an adjusting plate 12, and the bottom end of a group of fixed rods 4 close to one side of the transmission frame 1 is fixedly connected to the top of the adjusting plate 12, and a group of fixed rods 4 close to the other side of the transmission frame 1 is fixedly connected to the inner wall of the transmission frame 1, and movable rods 5 are movably installed at the top ends of the plurality of fixed rods 4, and the top ends of the plurality of movable rods 5 are fixedly connected with connecting blocks 7, and the opposite sides of the plurality of connecting blocks 7 are installed with mounting frames 8 through locking bolt blocks 9, and the side of the mounting frame 8 away from the connecting block 7 is rotatably installed with a grinding roller 10 through a rotating rod, and a waterproof motor 11 is installed at the top of the mounting frame 8, and the driving shaft of the waterproof motor 11 is connected to the rotating rod of the grinding roller 10, and a strip granite body 18 is provided at the top of the transmission roller 2 and on the inner side of the plurality of grinding rollers 10.

[0025] In this embodiment, a conveying motor is installed at the rear position of the side of the conveying frame 1 away from the driving cylinder 13, and the driving shaft of the conveying motor is connected to the rotating rollers of a plurality of conveying rollers 2 through a transmission wheel group. The driving shaft of the conveying motor rotates, driving the plurality of conveying rollers 2 to rotate, thereby facilitating the conveying of the strip granite body 18.

[0026] In this embodiment, the top end of the strip granite body 18 is fitted with the outer ring of the grinding roller 10 at both sides, and the mounting frame 8 is movably connected to the connecting block 7 through the locking bolt block 9. The locking bolt at the locking bolt block 9 is loosened to release the lock on the mounting frame 8, and then the mounting frame 8 can be rotated to adjust the grinding angle of the grinding roller 10, which has high flexibility in use.

[0027] In this embodiment, a locking knob 6 is threadedly connected to the upper position of one side of the fixed rod 4, and the end of the locking knob 6 extending into the fixed rod 4 is abutted against the outer circle of the movable rod 5. By loosening the locking knob 6, the fixation of the movable rod 5 can be released, and then the grinding height of the grinding roller 10 can be adjusted by pulling out or plugging back the movable rod 5.

[0028] In this embodiment, a plurality of push plates 14 are fixedly installed at the end of the driving shaft of the driving cylinder 13 near the front end of the transmission frame 1 through a mounting plate. The outer rings of the plurality of push plates 14 and the fixed rod 4 do not contact the outer ring of the transmission roller 2. When the strip granite body 18 passes by, the driving cylinder 13 can be started, and the driving shaft of the driving cylinder 13 is extended to drive the push plates 14 to move, thereby pushing the strip granite body 18 to a suitable position, and the push plates 14 and the fixed rod 4 do not contact the transmission roller 2, so as to prevent the transmission roller 2 from interfering with its movement.

[0029] In this embodiment, a storage box 15 is provided on the side of the transmission frame 1 away from the driving cylinder 13 and above a plurality of grinding rollers 10. A pressure block 17 is movably installed at the center of the bottom end of the storage box 15. The bottom end of the pressure block 17 is in contact with the top surface of the strip granite body 18, and the pressure block 17 and the strip granite body 18 are slidably connected. The setting of the pressure block 17 facilitates the pressing of the strip granite body 18 to prevent it from warping upward during grinding, and the sliding connection prevents the pressure block 17 from interfering with the normal transmission of the strip granite body 18.

[0030] In this embodiment, a plurality of cleaning nozzles 16 are arranged at equal distances from each other at the bottom end of the storage box 15, a water inlet pipe is provided at the rear position of the side of the storage box 15 away from the driving cylinder 13, and a drainage pipe is provided at the rear position inside the transmission frame 1. Through the cleaning nozzles 16, the water in the storage box 15 can be sprayed onto the strip granite body 18, so as to facilitate water spraying and dust reduction, and avoid dust flying and affecting the line of sight during the grinding process.

[0031] It should be noted that the utility model is a granite arc grinding device. When in use, first, the strip granite body 18 can be moved to the top of the transmission roller 2 with the help of an external tool. Since the plurality of transmission rollers 2 are connected to the driving shaft of the conveying motor through a transmission wheel group, the plurality of transmission rollers 2 can be driven to rotate by the driving shaft of the conveying motor, thereby conveying the strip granite body 18;

[0032] At the same time, during transportation, a push plate 14 is provided at the front position inside the transmission frame 1, and the bottom end of the push plate 14 is connected to the driving shaft of one of the driving cylinders 13, so that when the bar granite body 18 passes by, the driving cylinder 13 can be started, and the driving shaft of the driving cylinder 13 is extended to drive the push plate 14 to move, thereby pushing the bar granite body 18 to a suitable position;

[0033] After that, the strip granite body 18 is conveyed by the transmission roller 2 and corrected by the push plate 14 and enters between the grinding rollers 10. At this time, the waterproof motor 11 can be started, and the driving shaft of the waterproof motor 11 rotates to drive the grinding rollers 10 to rotate and grind the strip granite body 18, thereby removing its edges and corners.

[0034] During the grinding process, the water in the storage box 15 is sprayed onto the strip granite body 18 through the cleaning nozzle 16, so as to play the role of spraying water to reduce dust, avoid dust flying during the grinding process to affect the line of sight, and can wash away the dust on the strip granite body 18, so that the personnel can observe the grinding situation;

[0035] At the same time, during grinding, because the grinding roller 10 is installed on the connecting block 7 through the mounting frame 8 and the locking bolt block 9, and the connecting block 7 is fixed to the end of the driving shaft of another driving cylinder 13 through various components, the grinding roller 10 can be driven to move away from the grinding roller 10 installed on the other side during the grinding process by extending and retracting the driving shaft of another driving cylinder 13, so as to facilitate adjustment according to the size of the strip granite body 18.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
