Description

Technical Field

[0001] The invention relates to the technical field of stone cutting, and in particular to a building stone cutting device with a smooth cut surface. Background Art

[0002] The cutting of building stones is a crucial link in stone processing, which directly affects the use effect and economic benefits of stones. Early building stone cutting mainly relied on manual tools, such as hammers, chisels and wire saws. Although these tools are simple, they are labor-intensive, inefficient, and difficult to ensure cutting accuracy and surface quality. With the advent of the Industrial Revolution, mechanized cutting equipment began to appear, such as circular saws and band saws, which greatly improved the cutting speed and accuracy and reduced labor intensity. For example, a building stone cutting and polishing device in Publication No.: CN105773847A, when in use, the cutting wheel is rotated by starting a motor connected to the cutting wheel, and the cutting wheel moves downward, so that the cutting wheel can cut the stone. After cutting, the second gas is started. Cylinder, makes the stone move to the right, when the first push plate abuts against the left surface of the fifth support rod, the stone is on the right side of the fifth support rod, and then by starting the motor connected to the grinding wheel and the downward movement of the holding rod, the grinding wheel can grind the stone when it contacts the stone. However, during the cutting process, the cutting wheel can only move downward, and the rotating cutting wheel is circular, so that after the stone is cut, the two sides of the bottom of the stone are not cut by the cutting wheel, resulting in the stone being incompletely cut and unable to be separated. In addition, after the first push plate abuts against the left surface of the fifth support rod, the stone will not be able to move to the right again, resulting in the grinding wheel being able to grind only the edge of the cutting surface and unable to grind the entire cutting surface, and after the cutting is completed, the stone needs to be readjusted before it can be cut again, and the cutting efficiency is not high.

Screw rod 3 141 is rotatably installed inside the screw sleeves 23, and the cutting chamber 22 is located between the two screw rods 3 141. A motor 3 222 is fixedly installed inside the cutting chamber 22, and a rotating shaft 229 is fixedly connected to the output shaft of motor 3 222. A blade 1 231 and a blade 2 232 are slidably installed on the outer side of the rotating shaft 229. Blade 1 231 and blade 2 232 are both located inside the cutting chamber 22. Two rotating rods 131 are rotatably installed on both sides of the top of the base 1. The two rotating rods 131 are respectively located above the sliding rod 121 and the screw 2 122, and the support frame 21 is slidably installed on the outer side of the rotating rod 131.

[0030] Among them, the working principle of blade one 231 and blade two 232 is: when the stone is placed on the top of the support plate 11, the jack 111 is started and pushes the support plate 11 upward, so that the support plate 11 drives the stone to move upward, the motor three 222 is started and rotates forward, the blade one 231 and the blade two 232 rotate, the motor two 144 is started, the screw three 141 rotates, and drives the cutting chamber 22 to move back and forth horizontally through the screw sleeve two 23, and the cutting chamber 22 drives the blade one 231 and the blade two 232 to cut the stone. When the stone cuts out the slab, the motor one 124 is started, the screw two 122 rotates, and drives the support frame 21 to move forward, so that the cutting chamber 22 drives the blade one 231 and the blade two 232 to move forward, and continues to perform the next cutting.

[0031] like Figure 3 , Figure 6 and Figure 7 As shown, a rotating frame 223 is integrally formed inside the cutting chamber 22, and an adjusting cylinder 225 is rotatably installed inside the rotating frame 223. Screw hole 1 227 and screw hole 228 are respectively opened at both ends of the adjusting cylinder 225. The side walls of blade 1 231 and blade 232 are respectively integrally formed with screw cylinder 1 235 and screw cylinder 2 236.

Grinding sheets 234 are fixedly installed on the side walls of blade 232, and grinding rings 233 are fixedly installed on the side walls of blade 1 231.

[0032] Among them, the working principle of the adjustment cylinder 225 is: when the motor three 222 rotates forward, the blade one 231 and the blade two 232 drive the outer ratchet 224 to rotate, and at this time the outer ratchet 224 rotates inside the inner ratchet 226; when the motor three 222 rotates reversely, the inner ratchet 226 and the outer ratchet 224 engage with each other, so that the outer ratchet 224 is locked, and the screw cylinder one 235 and the screw cylinder two 236 rotate on the inner walls of the screw hole two 228 and the screw hole one 227 respectively, so that the blade one 231 and the blade two 232 move in opposite directions, adjusting the distance between the blade one 231 and the blade two 232.

[0033] Further references Figure 3 and Figure 7To explain, the rotation directions of screw hole 1 227 and screw hole 2 228 are opposite, and the rotation directions of screw barrel 1 235 and screw barrel 2 236 are also opposite. When motor 3 222 reverses, motor 1 124 also reverses, and the support frame 21 drives the cutting chamber 22 to move backward, so that the distance between the side wall of blade 1 231 and the cutting surface of the stone remains unchanged, and the grinding sheet 234 rotates with blade 2 232. In the process of blade 2 232 cutting the stone, the grinding sheet 234 grinds the cutting surface to make the cut surface smooth and flat, and the grinding ring 233 rotates with blade 1 231. When the cutting range of blade 1 231 is entirely located inside the stone, the grinding ring 233 grinds the edges and corners of the stone and the slab, so that the edges and corners do not need to be chamfered again after the stone slab is cut.

[0034] like Figure 2-Figure 5 As shown, a moving ring 314 and a slide cylinder 211 are slidably installed inside one of the support frames 21, the moving ring 314 is slidably installed on the outside of the slide cylinder 211, the slide cylinder 211 is slidably installed on the outside of the slide rod 121, and a rack 4 315 is integrally formed on the top of the moving ring 314. A gear 5 313 ​​is rotatably installed inside one of the support frames 21, and the rack 4 315 and the gear 5 313 ​​are meshed. The side walls on both sides of the slide cylinder 211 are respectively integrally formed with a positioning ring 1 213 and a positioning ring 2 214. The movable ring 314 is located between the positioning ring 1 213 and the positioning ring 2 214. The side wall of the blade 1 231 is rotatably installed with a push rod 31. The push rod 31 is located between the blade 1 231 and the rotating frame 223. The side wall of the push rod 31 is integrally formed with a rack 311. A slide groove 1 212 is opened on the side wall of one of the support frames 21. The rack 311 is slidably installed inside the slide groove 1 212. The top of the gear 5 313 ​​is integrally formed with a gear 4 312, and the gear 4 312 and the rack 3 311 are meshed.

[0035] Among them, the working principle of the moving ring 314 is: when the motor three 222 is reversed, the blade one 231 drives the push rod 31 to move, so that the rack three 311 slides inside the slide groove one 212 and meshes with the gear four 312, the gear four 312 drives the gear five 313 to rotate, the gear five 313 and the rack four 315 mesh with each other, so that the rack four 315 drives the moving ring 314 to move toward the positioning ring one 213.

[0036] like Figure 4 and Figure 5As shown, the positioning ring 214 is located inside the support frame 21, and a spring 215 is provided between the positioning ring 214 and the inner wall of the support frame 21. The side walls of the movable ring 314 and the positioning ring 214 are respectively integrally formed with a side plate 216 and a stop block 316. The side wall of the side plate 216 is fixedly installed with an electromagnetic block 217, and the electromagnetic block 217 is located between the side plate 216 and the stop block 316. A spring lock block 218 is slidably installed on the top of the electromagnetic block 217. A lock tooth 123 is provided on the side wall of the slide rod 121, and the spring lock block 218 and the lock tooth 123 cooperate with each other.

[0037] The working principle of the electromagnetic block 217 and the spring lock block 218 is as follows: when the motor 3 222 is reversed, the electromagnetic block 217 is started, so that the spring lock block 218 is contracted, and the slide 211 is unlocked. When the moving ring 314 moves, the slide 211 moves with the moving ring 314 through the spring 215. When the motor 3 222 stops reversing, the electromagnetic block 217 is closed, the spring lock block 218 contacts the lock tooth 1 123, and the slide 211 is locked again. When the side wall of the support frame 21 contacts the positioning After the ring 1 213 is moved, the motor 124 is turned off, the electromagnetic block 217 is started, the support frame 21 drives the cutting chamber 22 to move one station, the slide 211 is unlocked and moves toward the moving ring 314, and when the positioning ring 214 contacts the moving ring 314, the electromagnetic block 217 is turned off, the slide 211 is locked again, and the slide 211 moves one station. The one station that the support frame 21 drives the cutting chamber 22 to move and the one station that the slide 211 moves are equal to the distance between the blade 1 231 and the blade 2 232.

[0038] like Figure 2 , Figure 8 and Fig. 9 As shown, the side wall of the cutting chamber 22 is integrally formed with a rack 221, and the side wall of the support frame 21 is rotatably installed with an intermittent gear 133, the rack 221 and the intermittent gear 133 are meshed, and the intermittent gear 133 is slidably installed on the outer side of the rotating rod 131, and the side walls of the two rotating rods 131 are respectively fixedly installed with pulleys 134 and 135, and the side wall of the base 1 is rotatably installed with pulley 3 152, a belt 132 is provided between pulley 1 134 and pulley 3 152, and the side wall of pulley 3 152 is integrally formed with pulley 4 153, and a belt 132 is also provided between pulley 4 153 and pulley 2 135, the bottom of the support plate 11 is integrally formed with a rack 112 and a screw 113, and the side wall of pulley 3 152 is integrally formed with gear 3 151, and gear 3 151 and rack 1 112 are meshed.

[0039] The working principle of the intermittent gear 133 is as follows: the jack 111 drives the support plate 11 to move upward, so that the stone moves to a height of three quarters of the distance between the bottom of the cutting chamber 22 and the top of the base 1, and the cutting height of the blade 1 231 is half of the cutting height of the blade 2 232. When the cutting chamber 22 drives the blade 1 231 and the blade 2 232 to cut, the blade 1 231 cuts a quarter of the height of the stone, and the blade 2 232 cuts three quarters of the height of the stone. When the blade 1 231 and the blade 2 232 are moved out of the stone, the rack 2 221 and the intermittent gear 133 engage with each other, so that the rotating rod 131 rotates and drives the pulley 2 135 to rotate. The pulley 2 135 drives the gear 3 151 to rotate forward through the belt 132 and the pulley 4 153. The gear 3 151 is meshed with the rack 1 112, and the rack 1 112 drives the support plate 11 to move upward, so that the support plate 11 drives the stone. Move to the maximum height of the distance between the bottom of the cutting chamber 22 and the top of the base 1. When the cutting chamber 22 drives the blade 1 231 and the blade 2 232 to cut, the blade 1 231 and the blade 2 232 both cut downward by a quarter of the height at the previous cutting position. At this time, the blade 1 231 cuts half of the stone, and the blade 2 232 cuts the entire height of the stone. When the blade 1 231 and the blade 2 232 move out of the stone again, the rack 2 221 and the intermittent gear 133 engage with each other, so that the rotating rod 131 rotates and drives the pulley 1 134 to rotate. The pulley 1 134 drives the gear 3 151 to reverse through the belt 132 and the pulley 3 152. The gear 3 151 engages with the rack 1 112. The rack 1 112 drives the support plate 11 to move downward, so that the support plate 11 drives the stone to move to a height of three quarters of the distance between the bottom of the cutting chamber 22 and the top of the base 1.

[0040] like Figure 8 and Fig. 9 As shown, rack 112 and screw 113 are both slidably inserted into the bottom of the base 1, a screw sleeve 114 is rotatably installed at the bottom of the base 1, and the screw sleeve 114 is rotatably installed on the outside of the screw 113.

[0041] Among them, the working principle of the lock bar 154 is: when the gear three 151 rotates, the tooth surface 156 and the gear three 151 are meshed with each other, the tooth surface 156 drives the lock bar 154 to slide, the lock bar 154 drives the spring lock block 116 to move out of the lock groove 115, the screw sleeve 114 is unlocked, and the screw 113 slides; when the gear three 151 stops rotating, the spring 155 drives the lock bar 154 to return to its position, the spring lock block 116 contacts the lock groove 115, the screw sleeve 114 is locked, and the screw 113 is locked.

[0042] The specific working principle and use method of the present invention are explained in detail below: when the stone is placed on the support plate 11, the jack 111 is started, the jack 111 drives the support plate 11 to move upward, and the support plate 11 drives the stone to move upward. When the stone moves to a height of three-quarters of the distance between the bottom of the cutting chamber 22 and the top of the base 1, the motor three 222 and the motor two 144 are started and rotated forward, the motor three 222 drives the blade one 231 and the blade two 232 to rotate, the motor two 144 drives the screw three 141 to rotate, the screw three 141 drives the cutting chamber 22 to move, and the cutting chamber 22 drives the blade one 231 and the blade two 232 to cut When blade one 231 and blade two 232 move out of the stone, the cutting chamber 22 continues to move and drives the support plate 11 to move upward by one quarter of the height through rack two 221, so that the stone moves to the maximum height of the distance between the bottom of the cutting chamber 22 and the top of the base 1, and the cutting chamber 22 drives blade one 231 and blade two 232 to move in the opposite direction for cutting, so that blade one 231 cuts half of the stone, and blade two 232 cuts the entire height of the stone. When blade one 231 and blade two 232 move out of the stone again, the support plate 11 drives the stone to move downward by one quarter of the height, and at the same time, the motor one 124 drives the support frame 21 to move forward one station and continue cutting.

[0043] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.
