Description

Technical Field

[0001] This application relates to the technical field of concrete block processing, and particularly relates to a cutting device for concrete block processing. Background Art

[0002] Concrete blocks are building components made mainly from cement, aggregates (such as sand, gravel, cinder, etc.) and water. They have the advantages of high strength, good durability, convenient construction, and being economical, environmentally friendly, etc. They can effectively improve the stability and safety of buildings, and are convenient for construction. They can be made into different specifications and shapes according to needs, and are mainly used in building walls and enclosures.

[0003] The processing of concrete blocks mainly includes links such as raw material proportioning, mixing and stirring, mold forming, curing and hardening, etc. Among them, cutting is a key step in the later stage. Through a special cutting device, the hardened blocks are accurately segmented to meet the requirements of different sizes or special-shaped structures. Common cutting equipment includes metal cutting wires, concrete cutting machines, electric saws, etc.

[0004] Referring to the Chinese patent document with the authorization announcement number CN117734001B and the name of a cutting device for the production of aerated concrete blocks, when the cutting wire breaks, the clamping mechanism can clamp the spare wire and continue to cut the concrete, improving the timeliness of handling the accidental breakage of the cutting wire, saving the time for replacing the cutting wire, and being beneficial to improving the cutting efficiency.

[0005] For the above technical solution, a spare wire is arranged above the cutting wire to prevent the cutting wire from accidentally breaking. However, during the actual operation process, the spare wire will move together with the cutting wire and continuously rub against the concrete block, resulting in its own wear. Compared with the traditional cutting method, during the cutting process, the contact area between the wire and the concrete block is increased, exacerbating the overall wear of the wire, significantly shortening its effective service life, and having a relatively high use cost. Summary of the Invention

[0006] In view of this, this application provides a cutting device for concrete block processing, mainly used to solve the problem that when the cutting device for concrete block processing cuts, it exacerbates the wear of the cutting wire, reduces its service life, and has a relatively high use cost.

[0007] To solve the above technical problems, this application provides a cutting device for concrete block processing, including a frame, a lifting frame and a cutting wire. An elevating assembly for driving the lifting frame to move up and down is arranged on the frame. An movable frame is arranged on the lifting frame. Wire releasing assemblies and wire winding assemblies are respectively arranged on both sides of the bottom of the movable frame for installing the cutting wire. A first clamping member and a second clamping member for fixing the cutting wire are arranged between the wire releasing assembly and the wire winding assembly. A driving assembly for driving the movable frame to reciprocate is arranged on the lifting frame; A connecting member capable of locking with the movable frame is provided at the top of the second clamping member, and a displacement assembly for driving the connecting member to move left and right is provided on the frame. The wire winding assembly includes a second fixing plate, a wire winding reel is arranged on the second fixing plate, and a pressing assembly capable of pressing the cutting wire is arranged on one side of the wire winding reel. A first cylinder is arranged between the second fixing plate and the movable frame.

[0008] By adopting the above technical solution, the cutting wire is arranged between the wire feeding assembly and the wire winding assembly, and its two ends are fixed by the first clamping member and the second clamping member respectively to ensure that it always remains taut during the cutting process. Once the cutting wire breaks accidentally, the second clamping member will quickly drive the broken cutting wire forward to above the wire winding reel. After the pressing assembly presses the end of the cutting wire, the wire winding assembly will immediately start to rotate to automatically complete the reinstallation of the cutting wire. Subsequently, the second clamping member resets, and the first clamping member fixes the cutting wire again, and the cutting operation can be quickly restored. This process does not require manual intervention, significantly improving the replacement efficiency. In addition, the wire feeding assembly and the wire winding assembly cooperate with each other to regularly change the working area of the cutting wire, which not only reduces the risk of accidental breakage of the cutting wire, but also makes full use of the cutting wire on the wire feeding reel, effectively controlling the equipment usage cost.

[0009] Optionally, a side frame is arranged on one side of the second clamping member, a first pressing roller and a second pressing roller are arranged at the top of the side frame, gears meshing with each other are arranged at the bottoms of the first pressing roller and the second pressing roller, and a driving motor for driving the gears to rotate is arranged on the side frame.

[0010] By adopting the above technical solution, when the breaking position of the cutting wire is close to the second clamping member, under the action of the first pressing roller and the second pressing roller, the height of the wire head moving downward can be reduced, avoiding the phenomenon that the cutting wire cannot be fixed after moving to above the wire winding assembly, and reducing the limitations of equipment usage.

[0011] Optionally, brush rollers are arranged at the tops of the first pressing roller and the second pressing roller.

[0012] By adopting the above technical solution, after the cutting is completed, the rotating brush rollers can move left and right following the second clamping member to clean the concrete attached to the surface of the cutting wire, keeping it in a good cutting effect.

[0013] Optionally, the first clamping member includes a first fixing frame fixed at the bottom of the movable frame. A bidirectional lead screw is arranged on the first fixing frame. One end of the bidirectional lead screw penetrates through the first fixing frame and is provided with a driven gear. A first pressing plate and a second pressing plate are respectively threadedly connected to both sides of the bidirectional lead screw. A third motor is arranged below the first fixing frame, and a driving gear meshing with the driven gear is arranged on the output shaft of the third motor.

[0014] Optionally, the second clamping member includes a second fixing frame, and a lower pressing plate, an upper pressing plate and a second air cylinder are arranged inside the second fixing frame. The output end of the second air cylinder is fixedly connected to the lower pressing plate.

[0015] Optionally, the connecting member includes a vertical plate arranged on the top of the second fixing frame. An inserting plate is sleeved inside the vertical plate. A magnetic plate is arranged on the inserting plate. Two horizontally opposed clamping blocks are arranged inside the vertical plate. Fixing blocks are arranged on the clamping blocks. A second spring is arranged between the fixing blocks. After the magnetic plate is electrified, it can generate a magnetic force. The clamping blocks can be adsorbed on the magnetic plate under the action of the magnetic force. An installation groove adapted to the vertical plate is arranged on the movable frame. A clamping groove adapted to the clamping blocks is arranged on the installation groove.

[0016] By adopting the above technical solution, when cutting the concrete block, the second clamping member can be locked on the movable frame to cut the concrete block; when it is necessary to reinstall the broken cutting wire or clean the cutting wire, the second clamping member can be separated from the movable frame and move along with the displacement assembly.

[0017] Optionally, a water inlet pipe is arranged on one side of the vertical plate close to the side frame, and a nozzle is arranged at the bottom end of the water inlet pipe.

[0018] By adopting the above technical solution, while the brush roller cleans the cutting wire, the nozzle synchronously sprays water to wash the cutting wire. The two cooperate with each other to further strengthen the cleaning effect on the cutting wire.

[0019] Optionally, a wire take-up motor for driving the wire take-up reel to rotate is arranged on the second fixing plate, and a baffle is arranged on one side of the wire take-up reel; the wire pay-off assembly includes a first fixing plate, a wire pay-off reel and a wire pay-off motor. The wire pay-off motor is arranged on the first fixing plate and is used for driving the wire pay-off reel to rotate; the pressing assembly includes a sleeve arranged on one side of the wire take-up reel. A first spring is arranged between the sleeve and the wire take-up reel. A metal ring is arranged on one side of the sleeve. A magnetic ring is arranged on the side of the wire take-up reel far from the metal ring. After the magnetic ring is electrified, it can generate a magnetic force. The metal ring can be attached to the baffle under the action of the magnetic force.

[0020] By adopting the above technical solution, when the wire head clamped by the second clamping member falls on the wire take-up reel, the magnetic ring is electrified and adsorbs the metal ring, which can press the wire head on the wire take-up reel. At this time, the wire take-up motor drives the wire take-up reel to rotate, and the cutting wire can be re-wound on the wire take-up reel. The baffle can increase the blocking area, so that the wire head of the cutting wire can be pressed on the wire take-up reel, increasing the success rate of wire head winding.

[0021] Optionally, the lifting assembly includes a first lead screw rotatably connected to the frame. The first lead screw is threadedly connected to the lifting frame.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will combine the Figures 1 - 9 of the embodiments of this application to clearly and completely describe the technical solutions of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by this application.

[0028] Referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , this embodiment provides a cutting device for processing concrete blocks, including a frame 1, a cutting mechanism, a wire pay-off and take-up assembly, a wire fixing assembly, and a pressing assembly. Among them, the cutting mechanism includes a cutting wire 7, which is mainly responsible for cutting the concrete block in the up and down direction to process it into a predetermined size; the wire pay-off and take-up assembly undertakes the pay-off and take-up work of the cutting wire 7 and regularly adjusts the working area of the cutting wire 7 to ensure its uniform use; the wire fixing assembly is installed between the wire pay-off and take-up assemblies, which can keep the cutting wire 7 always in a taut state and can flexibly drive the wire head of the cutting wire 7 to move; the pressing assembly presses the wire head to ensure that the cutting wire 7 is smoothly wound on the wire pay-off and take-up assemblies to ensure the stable operation of the equipment. Multiple groups of cutting wires 7, wire pay-off and take-up assemblies, wire fixing assemblies, and pressing assemblies are provided, and their quantities can be adjusted according to production requirements in actual production.

[0029] Among them, with reference to Figure 1 and Figure 2 , the cutting mechanism includes a lifting frame 11, a cutting wire 7, a movable frame 2, a lifting assembly and a driving assembly. The lifting frame 11 is movably sleeved on the frame 1. Under the action of the lifting assembly, the lifting frame 11 can move up and down along the frame 1; the movable frame 2 is movably arranged on the lifting frame 11, and the cutting wire 7 is arranged on the movable frame 2 for cutting concrete blocks; the driving assembly is arranged on the lifting frame 11 for driving the movable frame 2 to reciprocate left and right. The lifting assembly includes a first lead screw 12 and a first motor 13. The output shaft of the first motor 13 is fixedly connected to the first lead screw 12 through a coupling. There are two first lead screws 12 and first motors 13, and the two first lead screws 12 and first motors 13 are symmetrically arranged on the frame 1. The first lead screw 12 is threadedly connected to the lifting frame 11. The driving assembly includes a connecting frame 23, a connecting rod 24 and a second motor 25. The connecting frame 23 is fixedly connected to one end of the movable frame 2. There are two connecting rods 24 in total, and the two are hinged to each other. One of the connecting rods 24 is hinged to the end of the connecting frame 23, and the second motor 25 is installed on the lifting frame 11, and its output shaft is fixedly connected to the other connecting rod 24. The connecting rod 24 is driven by the second motor 25 to realize linkage operation.

[0030] When cutting concrete blocks, the second motor 25 drives one of the connecting rods 24 to pull the end of the connecting frame 23 by the other connecting rod 24, so as to realize linkage operation, make the movable frame 2 drive the cutting wire 7 to reciprocate left and right, ensure that the cutting surface is flat and smooth, and guarantee the cutting quality. The first motor 13 drives the first lead screw 12 to rotate synchronously, so that the lifting frame 11 drives the movable frame 2 to move downward, and the whole concrete block is processed into a predetermined size by the cutting wire 7. Then, when the first motor 13 reverses, the movable frame 2 can drive the cutting wire 7 to move upward and reset.

[0031] Among them, with reference to Figure 2 , Figure 4 and Figure 5, the wire pay-off and take-up assembly includes a wire pay-off assembly and a wire take-up assembly. The wire pay-off assembly and the wire take-up assembly are respectively arranged on both sides of the bottom of the movable frame 2. The wire pay-off assembly includes a first fixed plate 21, a wire pay-off reel 211 and a wire pay-off motor 212. The first fixed plate 21 is fixedly connected to the movable frame 2. The wire pay-off motor 212 is installed on the first fixed plate 21 and is used to drive the wire pay-off reel 211 to rotate. The unused cutting wire 7 is wound around the wire pay-off reel 211. The wire take-up assembly includes a second fixed plate 22, a wire take-up reel 221, a wire take-up motor 222 and a first cylinder 227. The second fixed plate 22 is movably connected to the movable frame 2. The wire take-up motor 222 is arranged on the second fixed plate 22 and is used to drive the wire take-up reel 221 to rotate. The used cutting wire 7 is wound around the wire take-up reel 221. The first cylinder 227 is arranged between the second fixed plate 22 and the movable frame 2 and is used to drive the second fixed plate 22 to move up and down.

[0032] The unused cutting wire 7 is wound around the wire pay-off reel 211, and the used cutting wire 7 is wound around the wire take-up reel 221. When the cutting wire 7 has worked for a certain period of time, first release the fixation of the cable fixing component on it, and then start the wire pay-off motor 212 and the wire take-up motor 222 to wind the used cutting wire 7 onto the wire take-up reel 221 and let the unused cutting wire 7 unwind and move to the working position. Compared with the traditional cutting method, in this design, when the cutting wire 7 is worn, there is no need to replace it as a whole. Only by regularly adjusting its working area during the operation process can the use efficiency of the cutting wire 7 be fully exerted, effectively extending its service life and reducing the maintenance cost. If the broken wire remains on the cutting path, it may rub against the concrete block or block the new cutting wire 7, causing the new cutting wire 7 to deviate from the predetermined trajectory during cutting, resulting in defects such as skewed cuts, burrs, and cracks. Therefore, when the cutting wire 7 breaks accidentally, the wire take-up motor 222 can drive the wire take-up reel 221 to rotate, wind the drooping broken wire around the outside of the wire take-up reel 221, and then cooperate with the wire fixing structure to install and fix the cutting wire 7.

[0033] Among them, referring to Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9, the wire fixing assembly includes a first clamping member, a second clamping member, a connecting member, and a displacement assembly. The first clamping member includes a first fixing frame 26, a bidirectional lead screw 261, a first pressing plate 262, a second pressing plate 263, a third motor 264, a driving gear 265, and a driven gear 266. The first fixing frame 26 is fixedly arranged at the bottom of the movable frame 2. The bidirectional lead screw 261 is rotatably arranged at the bottom of the first fixing frame 26. The first pressing plate 262 and the second pressing plate 263 are respectively threadedly connected to both sides of the bidirectional lead screw 261. The driven gear 266 is arranged at the end of the bidirectional lead screw 261. The third motor 264 is installed below the first fixing frame 26. The driving gear 265 is arranged on the output shaft of the third motor 264 and is meshed with the driven gear 266. The second clamping member includes a second fixing frame 27, a lower pressing plate 271, an upper pressing plate 272, and a second cylinder 273. The lower pressing plate 271, the upper pressing plate 272, and the second cylinder 273 are all arranged inside the second fixing frame 27. The upper pressing plate 272 is fixedly connected to the second fixing frame 27. The lower pressing plate 271 is connected to the output end of the second cylinder 273. The connecting member includes a vertical plate 4, an insertion plate 41, a sliding sleeve 411, a clamping block 42, a fixing block 43, a magnetic plate 44, a clamping groove 45, a second spring 46, and an installation groove 28. The vertical plate 4 is arranged at the top of the second fixing frame 27. The insertion plate 41 is inserted inside the vertical plate 4. The sliding sleeve 411 is arranged at the top end of the insertion plate 41. There are two clamping blocks 42, and the two clamping blocks 42 are horizontally arranged opposite to each other inside the vertical plate 4. The magnetic plate 44 is arranged on the insertion plate 41. The fixing blocks 43 are arranged on both sides of the clamping block 42. The second spring 46 is arranged between the fixing blocks 43. After the magnetic plate 44 is energized, it can generate a magnetic force, and the clamping block 42 can be adsorbed on the magnetic plate 44 under the action of the magnetic force. The installation groove 28 is arranged on the movable frame 2 and is adapted to the vertical plate 4. The clamping groove 45 is arranged on the installation groove 28, and the clamping groove 45 is adapted to the clamping block 42. The displacement assembly includes a cross plate 6, a second lead screw 61, and a fourth motor 62. The cross plate 6 is arranged at the top of the frame 1. The second lead screw 61 is rotatably connected to the frame 1. The fourth motor 62 is installed on the frame 1 and is used to drive the second lead screw 61 to rotate.

[0034] After the cutting wire 7 is released from the wire pay-off reel 211, it will pass through the second clamping member and the first clamping member in sequence, and then be wound around the wire take-up reel 221. The first clamping member and the second clamping member will clamp the passing cutting wire 7 to keep it in a taut state to maintain a good cutting effect. When the cutting wire 7 accidentally breaks, the lifting assembly drives the lifting frame 11 and the movable frame 2 to reset upward, and makes the connecting member lock with the second clamping member. Subsequently, the wire take-up assembly is activated to wind the broken cutting wire 7 onto the wire take-up reel 221. Immediately afterwards, the displacement assembly pushes the second clamping member towards the wire take-up assembly through the connecting member, and at the same time the first clamping member opens to make way for the second clamping member. At this time, the first cylinder 227 drives the wire take-up assembly to descend, so that the wire head of the cutting wire 7 clamped by the second clamping member falls on the surface of the wire take-up reel 221. After the pressing assembly presses the wire head, the wire take-up reel 221 starts to rotate, automatically completing the reinstallation of the cutting wire 7 on the wire pay-off and take-up assemblies, and the operation can be quickly restored. During actual use, arc-shaped grooves for the cutting wire 7 to pass through are provided on the opposite surfaces of the first pressing plate 262 and the second pressing plate 263, and on the opposite surfaces of the lower pressing plate 271 and the upper pressing plate 272, which can increase the contact area with the cutting wire 7, improve the friction force, and make the fixation of the cutting wire 7 more reliable. In addition, rollers in contact with the cross plate 6 can be provided at the top of the sliding sleeve 411 to reduce the friction force during the movement of the sliding sleeve 411 and make its movement smoother.

[0035] In addition, referring to Figure 5 and Figure 6 , the pressing assembly includes a housing 223, a baffle 224, a metal ring 225, a magnetic ring 226, and a first spring 228. The housing 223 is movably sleeved on one side of the wire take-up reel 221. The first spring 228 is arranged between the housing 223 and the wire take-up reel 221. The metal ring 225 is arranged on one side of the housing 223. The magnetic ring 226 is arranged on the side of the wire take-up reel 221 away from the metal ring 225. The baffle 224 is arranged on the side of the wire take-up reel 221 away from the housing 223. After the magnetic ring 226 is energized, it can generate a magnetic force, and the metal ring 225 can fit with the baffle 224 under the action of the magnetic force.

[0036] The baffle 224 can increase the blocking area, so that the wire head of the cutting wire 7 can be pressed tightly on the wire take-up reel 221, increasing the success rate of wire head winding. After the wire head of the cutting wire 7 clamped by the second clamping member falls on the surface of the wire take-up reel 221, the magnetic ring 226 is energized to generate a magnetic force to adsorb the metal ring 225. Under the action of the metal ring 225 and the baffle 224, the wire head is pressed tightly. Subsequently, the wire take-up motor 222 drives the wire take-up reel 221 to rotate, and the cutting wire 7 can be rewound on the wire take-up reel 221.

[0037] Referring to Figure 2 and Figure 3, a rotating assembly is provided on one side of the second clamping member. The rotating assembly includes a side frame 3, a first pressing roller 31, a second pressing roller 32, a gear 34, and a driving motor 35. The side frame 3 is fixedly installed on one side of the lower pressing plate 271, and the first pressing roller 31 and the second pressing roller 32 are horizontally arranged at its top. Mutually meshing gears 34 are correspondingly installed at the bottoms of the two pressing rollers. The driving motor 35 is installed on the side frame 3 and serves as a power source to drive the gear 34 to rotate, thereby driving the first pressing roller 31 and the second pressing roller 32 to rotate synchronously.

[0038] During normal operation, the cutting wire 7 passes between the first pressing roller 31 and the second pressing roller 32. Due to the uncertainty of the position where the cutting wire 7 accidentally breaks, when the break point is close to the second clamping member, the sagging distance of the wire head is limited, and it is easy to have the problem of being unable to contact the take-up reel 221, thus affecting its installation. Therefore, when the wire head is too short, the driving motor 35 drives the first pressing roller 31 and the second pressing roller 32 to rotate synchronously through the driving gear 34, and at the same time, cooperates with the wire feeding assembly to feed the wire, effectively increasing the sagging length of the wire head and improving the success rate of installing and fixing the cutting wire 7.

[0039] Refer to Figure 3 , brush rollers 33 are provided at the tops of both the first pressing roller 31 and the second pressing roller 32. Brush hairs are circumferentially arranged on the outer side of the brush roller 33.

[0040] After each cutting operation is completed, the lower pressing plate 271 drives the first pressing roller 31 and the second pressing roller 32 to move downward, so that the cutting wire 7 is located between the brush rollers 33. The output shaft of the driving motor 35 drives the first pressing roller 31 and the second pressing roller 32 to rotate through the gear 34, and the first pressing roller 31 and the second pressing roller 32 drive the brush rollers 33 at their tops to rotate. Along with the movement of the second clamping member, the brush rollers 33 can clean the concrete attached to the surface of the cutting wire 7 to ensure that the cutting wire 7 maintains good cutting performance.

[0041] Refer to Figure 3 , a water inlet pipe 5 communicating with an external water source is provided on one side of the vertical plate 4 close to the side frame 3, and a nozzle 51 is provided at the bottom end of the water inlet pipe 5.

[0042] When cleaning the cutting wire 7, the external water source continuously supplies water to the nozzle 51 through the water inlet pipe 5. While the brush rollers 33 mechanically clean the cutting wire 7, the nozzle 51 simultaneously sprays water for rinsing. The two work together, and through the dual cleaning of mechanical friction and water flow scouring, the cleaning effect on the cutting wire 7 is further improved.

[0043] The implementation principle of a cutting device for processing concrete blocks in an embodiment of the present application is: When the equipment is running, the unused cutting wire 7 is wound on the unwinding reel 211, and then wound on the take-up reel 221 after passing through the second clamping member and the first clamping member, and is clamped by the first clamping member (the output shaft of the third motor 264 drives the driving gear 265 to rotate the driven gear 266, and the driven gear 266 drives the bidirectional lead screw 261 to move the first pressing plate 262 and the second pressing plate 263 in opposite directions at the same time, thereby clamping the passing cutting wire 7) and the second clamping member (the output end of the second cylinder 273 drives the lower pressing plate 271 to move upward, and clamps the passing cutting wire 7 between the lower pressing plate 271 and the upper pressing plate 272), so that the cutting wire 7 is in a taut state. The first motor 13 drives the first lead screw 12 to rotate, so that the lifting frame 11 moves downward along the frame 1, and at the same time, the second motor 25 drives the connecting rod 24 to work in conjunction, and drives the movable frame 2 to make the cutting wire 7 reciprocate left and right to cut the concrete blocks. After the cutting is completed, the first motor 13 rotates in the reverse direction to move the lifting frame 11 and the movable frame 2 upward and reset.

[0044] When the cutting wire 7 is worn out after working for a long time, the first clamping member and the second clamping member loosen the cutting wire 7, and the pay-off motor 212 and the take-up motor 222 operate synchronously to move the unused cutting wire 7 on the pay-off reel 211 to the working area, and the worn cutting wire 7 is wound around the take-up reel 221, so that the cutting wire 7 is fully utilized, its service life is extended and the maintenance cost is reduced.

[0045] After the cutting wire 7 is accidentally broken, the first motor 13 drives the first lead screw 12 to rotate, so that the lifting frame 11 and the movable frame 2 are quickly reset upward, and the magnetic plate 44 in the connecting member is energized to attract the card block 42, and the second spring 46 is compressed. At this time, the card block 42 completely enters the vertical plate 4. When the vertical plate 4 is sleeved on the plug plate 41, the magnetic plate 44 is powered off, and under the action of the second spring 46, the card block 42 is inserted into the card slot 45, completing the locking of the vertical plate 4 and the second fixed frame 27. At the same time, the take-up motor 222 drives the take-up reel 221 to rotate, and the broken cutting wire 7 is wound on the take-up reel 221. The fourth motor 62 drives the second lead screw 61 to rotate, pushing the second clamping member to move toward the take-up assembly, and at the same time the first clamping member opens to allow the second clamping member to pass. The first cylinder 227 drives the take-up assembly to descend, so that the wire head clamped by the second clamping member falls on the take-up reel 221. Subsequently, the magnetic ring 226 is energized to attract the metal ring 225, pressing the wire head onto the take-up reel 221, and the take-up motor 222 drives the take-up reel 221 to rotate, reinstalling the cutting wire 7, and restoring the device to normal operation. If the broken wire head is too short, the drive motor 35 drives the first pressure roller 31 and the second pressure roller 32 to rotate through the gear 34, and cooperates with the release reel 211 to increase the sagging length of the cutting wire 7, thereby improving the success rate of the installation and fixation of the cutting wire 7.

[0046] After the cutting operation is completed, the first motor 13 drives the first lead screw 12 to rotate, causing the lifting frame 11 and the movable frame 2 to move upward and reset. The second cylinder 273 drives the lower pressing plate 271 to move downward, causing the first pressing roller 31 and the second pressing roller 32 to descend, and placing the cutting wire 7 between the brush rollers 33. The drive motor 35 drives the first pressing roller 31 and the second pressing roller 32 to drive the brush rollers 33 to rotate, cleaning the concrete adhering to the surface of the cutting wire 7. At the same time, the water inlet pipe 5 sprays water through the nozzle 51 to wash the cutting wire 7, and the cleaning operation is carried out by the cooperation of mechanical friction and water flow scouring. After cleaning, the second clamping member resets to prepare for the next operation.

[0047] The above are the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art of the present technology, without departing from the principle described in the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
