Description

Technical Field

[0001] The present application relates to the technical field of concrete block processing, and in particular to a cutting device for concrete block processing. Background Art

[0002] Concrete blocks are building components made of cement, aggregate (sand, gravel, cinder, etc.) and water as the main raw materials. They have the advantages of high strength, good durability, convenient construction, economy and environmental protection. They can effectively improve the stability and safety of buildings. They are easy to construct and can be made into different specifications and shapes according to needs. They are mainly used in building walls and fences.

[0003] Concrete block processing primarily involves raw material proportioning, mixing, molding, and curing. Cutting is a critical step in the final stage, using specialized cutting equipment to precisely segment the hardened blocks to meet the needs of varying sizes or shapes. Common cutting equipment includes metal cutting wires, concrete cutters, and electric saws.

[0004] Referring to the Chinese patent document with authorization announcement number CN117734001B, entitled "A cutting device for aerated concrete block production", when the cutting wire is disconnected, the clamping mechanism can clamp the spare wire and continue cutting the concrete, thereby improving the timeliness of handling the accidental disconnection of the cutting wire, saving the time of replacing the cutting wire, and helping to improve cutting efficiency.

[0005] The aforementioned technical solution incorporates a backup wire above the cutting wire to prevent accidental breakage. However, during operation, the backup wire moves with the cutting wire, continuously engaging with the concrete blocks and causing wear. Compared to traditional cutting methods, this increases the contact area between the wire and the concrete blocks, exacerbating overall wear on the wire, significantly shortening its useful life and increasing its cost. Summary of the Invention

[0006] In view of this, the present application provides a cutting device for processing concrete blocks, which is mainly used to solve the problem that the cutting device for processing concrete blocks aggravates the wear of the cutting wire during cutting, reduces its service life, and has high usage costs.

[0007] To solve the above technical problems, the present application provides a cutting device for processing concrete blocks, comprising a frame, a lifting frame, and a cutting wire. The frame is provided with a lifting assembly for driving the lifting frame to move up and down. The lifting frame is provided with a movable frame. A wire-paying assembly and a wire-taking assembly are respectively provided 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 provided between the wire-paying assembly and the wire-taking assembly. The lifting frame is provided with a driving assembly for driving the movable frame to reciprocate.

[0008] A connecting piece that can be locked with the movable frame is provided on the top of the second clamping piece, and a displacement component for driving the connecting piece to move left and right is provided on the frame. The wire taking-up component includes a second fixed plate, and a wire taking-up reel is provided on the second fixed plate. A pushing component that can press the cutting wire is provided on one side of the wire taking-up reel, and a first cylinder is provided between the second fixed plate and the movable frame.

[0009] By adopting the above technical solution, the cutting wire is arranged between the pay-out assembly and the take-up assembly, and its two ends are fixed by the first clamping member and the second clamping member respectively, ensuring 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 the top of the take-up reel. After the pushing assembly presses the end of the cutting wire, the take-up assembly will start to rotate and automatically reinstall the cutting wire. Subsequently, the second clamping member is reset, and the first clamping member fixes the cutting wire again, and the cutting operation can be quickly resumed. This process does not require manual intervention, which significantly improves the replacement efficiency. In addition, the pay-out assembly and the take-up assembly work together 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 pay-out reel, effectively controlling the cost of equipment use.

[0010] Optionally, a side frame is provided on one side of the second clamping member, a first pressure roller and a second pressure roller are provided on the top of the side frame, mutually meshing gears are provided on the bottom of the first pressure roller and the second pressure roller, and a drive motor for driving the gears to rotate is provided on the side frame.

[0011] By adopting the above technical solution, when the breaking position of the cutting wire is close to the second clamping part, under the action of the first pressure roller and the second pressure roller, the height of the wire head can be reduced, avoiding the phenomenon that the cutting wire cannot be fixed after moving to the top of the take-up assembly, thereby reducing the limitations of the equipment use.

[0012] Optionally, brush rollers are provided on the tops of the first pressing roller and the second pressing roller.

[0013] By adopting the above technical solution, after cutting is completed, the rotating brush roller can move left and right following the second clamping member to clean the concrete attached to the surface of the cutting wire, so as to maintain a good cutting effect.

[0014] Optionally, the first clamping member includes a first fixed frame fixed to the bottom of the movable frame, a bidirectional screw is provided on the first fixed frame, one end of the bidirectional screw passes through the first fixed frame and is provided with a driven gear, and the two sides of the bidirectional screw are respectively threadedly connected with a first pressure plate and a second pressure plate, a third motor is provided below the first fixed frame, and a driving gear meshing with the driven gear is provided on the output shaft of the third motor.

[0015] Optionally, the second clamping member includes a second fixing frame, a lower pressing plate, an upper pressing plate and a second cylinder are provided inside the second fixing frame, and an output end of the second cylinder is fixedly connected to the lower pressing plate.

[0017] By adopting the above technical solution, when cutting concrete blocks, the second clamping member can be locked on the movable frame to cut the concrete blocks; when the broken cutting wire needs to be reinstalled or cleaned, the second clamping member can be separated from the movable frame and move with the displacement assembly.

[0018] Optionally, a water inlet pipe is provided on a side of the vertical plate close to the side frame, and a nozzle is provided at the bottom end of the water inlet pipe.

[0019] By adopting the above technical solution, while the brush roller cleans the cutting wire, the nozzle synchronously sprays water to rinse the cutting wire. The two cooperate with each other to further enhance the cleaning effect of the cutting wire.

[0020] Optionally, a take-up motor for driving the take-up reel to rotate is provided on the second fixed plate, and a baffle is provided on one side of the take-up reel; the pay-off assembly includes a first fixed plate, a pay-off reel and a pay-off motor, and the pay-off motor is provided on the first fixed plate for driving the pay-off reel to rotate; the pushing assembly includes a shell provided on one side of the take-up reel, a first spring is provided between the shell and the take-up reel, a metal ring is provided on one side of the shell, and a magnetic ring is provided on the side of the take-up reel away from the metal ring. The magnetic ring can generate magnetic force when energized, and the metal ring can fit with the baffle under the action of the magnetic force.

[0021] By adopting this technical solution, when the wire end held by the second clamping member falls onto the take-up reel, the magnetic ring is energized and attracts the metal ring, pressing the wire end onto the take-up reel. The take-up motor then drives the take-up reel to rotate, allowing the cutting wire to be rewound onto the reel. The baffle increases the blocking area, allowing the cutting wire end to be pressed tightly onto the take-up reel, thereby increasing the success rate of wire winding.

[0022] Optionally, the lifting assembly includes a first screw rotatably connected to the frame, the first screw is threadedly connected to the lifting frame, a first motor is provided on the top of the frame, and the output shaft of the first motor is fixedly connected to the first screw; the driving assembly includes a connecting frame provided at one end of the movable frame, a connecting rod is hinged on the connecting frame, and a second motor is provided on the lifting frame.

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application Figures 1-9 , the technical solutions of the embodiments of the present application are clearly and completely described. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of this application.

[0038] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5This embodiment provides a cutting device for processing concrete blocks, including a frame 1, a cutting mechanism, a retractable wire assembly, a wire fixing assembly, and a pushing assembly. Among them, the cutting mechanism includes a cutting wire 7, which is mainly responsible for cutting the concrete blocks in the up and down directions and processing them into predetermined sizes; the retractable wire assembly is responsible for the retracting and releasing 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 retractable wire assemblies, which can keep the cutting wire 7 in a taut state at all times, and can flexibly drive the wire head of the cutting wire 7 to move; the pushing assembly ensures that the cutting wire 7 is smoothly wound on the retractable wire assembly by pressing the wire head, ensuring stable operation of the equipment. There are multiple groups of cutting wire 7, retractable wire assembly, wire fixing assembly, and pushing assembly, and in actual production, their number can be adjusted according to production needs.

[0039] Among them, reference 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 drive assembly. The lifting frame 11 is movably mounted on the frame 1 and, under the action of the lifting assembly, can move up and down along the frame 1. The movable frame 2 is movably mounted on the lifting frame 11, and the cutting wire 7 is mounted on the movable frame 2 for cutting concrete blocks. The drive assembly is mounted on the lifting frame 11 and is used to drive the movable frame 2 to move back and forth. The lifting assembly includes a first screw 12 and a first motor 13. The output shaft of the first motor 13 is fixedly connected to the first screw 12 via a coupling. There are two first screws 12 and first motor 13, each of which is symmetrically arranged on the frame 1. The first screw 12 is threadedly connected to the lifting frame 11. The drive 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, which are hinged to each other. One of the connecting rods 24 is hinged at 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 the linkage operation.

[0040] When cutting concrete blocks, the second motor 25 drives one of the connecting rods 24, causing the other connecting rod 24 to pull the end of the connecting frame 23, thereby achieving a coordinated operation. The movable frame 2 drives the cutting wire 7 to reciprocate left and right, ensuring a smooth cut surface and guaranteed cutting quality. The first motor 13 drives the first lead screw 12 to rotate synchronously, causing the lifting frame 11 to move the movable frame 2 downward. The entire concrete block is processed to the predetermined size using the cutting wire 7. The first motor 13 then reverses, causing the movable frame 2 to move the cutting wire 7 upward and reset.

[0041] Among them, reference Figure 2 、 Figure 4 and Figure 5 The pay-off and rewinding assembly includes a pay-off assembly and a take-up assembly. The pay-off assembly and the take-up assembly are respectively arranged on both sides of the bottom of the movable frame 2. The pay-off assembly includes a first fixed plate 21, a pay-off reel 211 and a pay-off motor 212. The first fixed plate 21 is fixedly connected to the movable frame 2. The pay-off motor 212 is installed on the first fixed plate 21 and is used to drive the pay-off reel 211 to rotate. The unused cutting wire 7 is wound on the pay-off reel 211. The take-up assembly includes a second fixed plate 22, a take-up reel 221, a take-up motor 222 and a first cylinder 227. The second fixed plate 22 is movably connected to the movable frame 2. The take-up motor 222 is arranged on the second fixed plate 22 and is used to drive the take-up reel 221 to rotate. The used cutting wire 7 is wound on the 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.

[0042] The unused cutting wire 7 is wound around the pay-off reel 211, and the used cutting wire 7 is wound around the take-up reel 221. When the cutting wire 7 has been working for a certain period of time, the cable fixing assembly is first released to fix it, and then the pay-off motor 212 and the take-up motor 222 are started to wind the used cutting wire 7 onto the take-up reel 221, and the unused cutting wire 7 is unfolded and moved to the working position. Compared with the traditional cutting method, this design does not require the entire cutting wire 7 to be replaced when it is worn. It only needs to adjust its working area regularly during the operation to give full play to the effectiveness of the cutting wire 7, effectively extend its service life and reduce maintenance costs. If broken wires remain on the cutting path, they may rub against the concrete blocks 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 incisions, burrs, and cracks. Therefore, when the cutting wire 7 breaks accidentally, the take-up motor 222 can drive the take-up reel 221 to rotate, winding the broken wire hanging downwards around the outside of the take-up reel 221, and then cooperating with the wire fixing structure to install and fix the cutting wire 7.

[0043] Among them, reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 and Figure 9The 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 fixed frame 26, a bidirectional screw 261, a first pressure plate 262, a second pressure plate 263, a third motor 264, a driving gear 265 and a driven gear 266. The first fixed frame 26 is fixedly set at the bottom of the movable frame 2, the bidirectional screw 261 is rotatably set at the bottom of the first fixed frame 26, the first pressure plate 262 and the second pressure plate 263 are respectively threadedly connected to the two sides of the bidirectional screw 261, the driven gear 266 is set at the end of the bidirectional screw 261, the third motor 264 is installed below the first fixed frame 26, and the driving gear 265 is set on the output shaft of the third motor 264 and is meshed with the driven gear 266; the second clamping member includes a second fixed frame 27, a lower pressure plate 271, an upper pressure plate 272 and a second cylinder 273. The lower pressure plate 271, upper pressure plate 272, and second cylinder 273 are all positioned within the second fixed frame 27. The upper pressure plate 272 is fixedly connected to the second fixed frame 27, and the lower pressure plate 271 is connected to the output end of the second cylinder 273. The connector includes a vertical plate 4, an insert plate 41, a sleeve 411, a clamping block 42, a fixing block 43, a magnetic plate 44, a slot 45, a second spring 46, and a mounting slot 28. The vertical plate 4 is positioned at the top of the second fixed frame 27, with the insert plate 41 inserted within the vertical plate 4, and the sleeve 411 positioned at the top of the insert plate 41. There are two clamping blocks 42, which are positioned horizontally opposite each other within the vertical plate 4. The magnetic plate 44 is positioned on the insert plate 41, with fixing blocks 43 positioned on either side of the clamping block 42, and a second spring 46 positioned between the fixing blocks 43. When energized, the magnetic plate 44 generates a magnetic force, which causes the clamping block 42 to adhere to the magnetic plate 44. Mounting slot 28 is provided on movable frame 2 and mates with vertical plate 4. A retaining slot 45 is provided on mounting slot 28 and mates with retaining block 42. The displacement assembly includes a cross plate 6, a second lead screw 61, and a fourth motor 62. Cross plate 6 is mounted on top of frame 1. Second lead screw 61 is rotatably connected to frame 1. Fourth motor 62 is mounted on frame 1 and drives second lead screw 61 in rotation.

[0044] After the cutting wire 7 is released from the payout reel 211, it passes through the second clamping member and the first clamping member in sequence before being wound onto the takeup reel 221. The first and second clamping members clamp the passing cutting wire 7, keeping it taut to maintain a good cutting effect. If the cutting wire 7 accidentally breaks, the lifting assembly drives the lifting frame 11 and the movable frame 2 to reset upward, and the connecting member and the second clamping member are locked. The takeup assembly then activates, winding the broken cutting wire 7 onto the takeup reel 221. Next, the displacement assembly pushes the second clamping member toward the takeup assembly via the connecting member, while the first clamping member opens to make way for the second clamping member. At this point, the first cylinder 227 drives the takeup assembly downward, causing the end of the cutting wire 7 held by the second clamping member to fall onto the surface of the takeup reel 221. After the pushing assembly compresses the end of the cutting wire, the takeup reel 221 begins to rotate, automatically reinstalling the cutting wire 7 on the payout assembly, allowing operation to resume quickly. In actual use, the opposing surfaces of the first and second pressing plates 262, 263, as well as the opposing surfaces of the lower and upper pressing plates 271, 272, are provided with arcuate grooves for the passage of the cutting wire 7. This increases the contact area with the cutting wire 7, improves friction, and securely secures the cutting wire 7. Furthermore, a roller that contacts the cross plate 6 can be provided on the top of the sliding sleeve 411 to reduce friction during movement of the sliding sleeve 411, making its movement smoother.

[0045] In addition, refer to Figure 5 and Figure 6 The pushing 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 mounted on one side of the take-up reel 221. The first spring 228 is disposed between the housing 223 and the take-up reel 221. The metal ring 225 is disposed on one side of the housing 223, and the magnetic ring 226 is disposed on the side of the take-up reel 221 away from the metal ring 225. The baffle 224 is disposed on the side of the take-up reel 221 away from the housing 223. When energized, the magnetic ring 226 generates a magnetic force, which causes the metal ring 225 to adhere to the baffle 224.

[0046] Baffle 224 increases the blocking area, allowing the end of the cutting wire 7 to be pressed tightly against the take-up reel 221, thereby increasing the success rate of wire winding. When the end of the cutting wire 7, clamped by the second clamping member, falls onto the surface of the take-up reel 221, the magnetic ring 226 is energized to generate a magnetic force that attracts the metal ring 225. Under the action of the metal ring 225 and baffle 224, the wire end is pressed tightly. Subsequently, the take-up motor 222 drives the take-up reel 221 to rotate, allowing the cutting wire 7 to be rewound onto the take-up reel 221.

[0047] Reference Figure 2 and Figure 3A rotating assembly is provided on one side of the second clamping member. The rotating assembly includes a side frame 3, a first pressure roller 31, a second pressure roller 32, a gear 34, and a drive motor 35. The side frame 3 is fixedly mounted on one side of the lower pressure plate 271, with the first pressure roller 31 and the second pressure roller 32 horizontally arranged on its top. Gears 34 that mesh with each other are installed at the bottom of the two pressure rollers. The drive motor 35 is mounted on the side frame 3 and serves as a power source to drive the gear 34 to rotate, thereby driving the first pressure roller 31 and the second pressure roller 32 to rotate synchronously.

[0048] During normal operation, the cutting wire 7 passes between the first pressure roller 31 and the second pressure roller 32. Due to the uncertainty of the location of the accidental breakage of the cutting wire 7, when the breakage point is close to the second clamping member, the wire head can only droop a limited distance, which can easily lead to the problem of not being able to contact the take-up reel 221, thus affecting its installation. To this end, when the wire head is too short, the drive motor 35 drives the first pressure roller 31 and the second pressure roller 32 to rotate synchronously via the drive gear 34, and at the same time cooperates with the pay-off assembly to pay off the wire, effectively increasing the length of the wire head that droops and improving the success rate of the installation and fixation of the cutting wire 7.

[0049] Reference Figure 3 The tops of the first pressing roller 31 and the second pressing roller 32 are both provided with a brush roller 33. The outer circumference of the brush roller 33 is provided with bristles.

[0050] After each cutting operation is completed, the lower pressing plate 271 drives the first and second pressing rollers 31, 32 to move downward, positioning the cutting wire 7 between the brush rollers 33. The output shaft of the drive motor 35 drives the first and second pressing rollers 31, 32 to rotate via the gear 34. The first and second pressing rollers 31, 32 drive the brush rollers 33 on top of them to rotate. As the second clamping member moves, the brush rollers 33 clean the concrete adhering to the surface of the cutting wire 7, ensuring that the cutting wire 7 maintains good cutting performance.

[0051] Reference Figure 3 A water inlet pipe 5 connected to 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.

[0052] 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 roller 33 mechanically cleans the cutting wire 7, the nozzle 51 simultaneously sprays water for flushing. The two work together to further improve the cleaning effect of the cutting wire 7 through the dual cleaning of mechanical friction and water flushing.

[0053] The implementation principle of a cutting device for processing concrete blocks in the embodiment of the present application is as follows:

[0054] During operation, unused cutting wire 7 is wound around payout reel 211, passed through the second and first clamping members, and then wound onto takeup reel 221. The wire is then 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, which in turn drives the bidirectional lead screw 261 to simultaneously move the first and second pressure plates 262, 263 in opposite directions, thereby clamping the passing cutting wire 7) and the second clamping member (the output end of the second cylinder 273 drives the lower pressure plate 271 upward, clamping the passing cutting wire 7 between the lower and upper pressure plates 271, 272). This tightens the cutting wire 7, keeping it taut. The first motor 13 rotates the first lead screw 12, causing the lifting frame 11 to move downward along the frame 1. Simultaneously, the second motor 25 drives the connecting rod 24, which in turn drives the movable frame 2 to cause the cutting wire 7 to reciprocate left and right, thereby cutting 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.

[0055] 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, so that the unused cutting wire 7 on the pay-off reel 211 is moved 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.

[0056] After the cutting wire 7 accidentally breaks, the first motor 13 drives the first screw 12 to rotate, causing the lifting frame 11 and the movable frame 2 to quickly return to the upward position. The magnetic plate 44 in the connecting member is energized to attract the block 42, and the second spring 46 is compressed. At this time, the block 42 is completely inserted into the vertical plate 4. When the vertical plate 4 is mounted on the plug plate 41, the magnetic plate 44 is de-energized. Under the action of the second spring 46, the block 42 is snapped into the 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, winding the broken cutting wire 7 onto the take-up reel 221. The fourth motor 62 drives the second screw 61 to rotate, pushing the second clamping member to move toward the take-up assembly. At the same time, the first clamping member opens to allow the second clamping member to pass through. The first cylinder 227 drives the take-up assembly to descend, causing the wire head clamped by the second clamping member to fall onto the take-up reel 221. Subsequently, the magnetic ring 226 is energized to attract the metal ring 225, pressing the wire end tightly against the take-up reel 221. The take-up motor 222 drives the take-up reel 221 to rotate, reinstalling the cutting wire 7 and restoring normal operation of the device. If the broken wire end is too short, the drive motor 35 drives the first and second pressure rollers 31 and 32 to rotate via the gear 34, cooperating with the release reel 211 to increase the sagging length of the cutting wire 7 and improve the success rate of the installation and fixation of the cutting wire 7.

[0057] After the cutting operation is completed, the first motor 13 rotates the first lead screw 12, causing the lifting frame 11 and movable frame 2 to move upward and reset. The second cylinder 273 then moves the lower pressure plate 271 downward, lowering the first and second pressure rollers 31, 32, placing the cutting wire 7 between the brush rollers 33. The drive motor 35 drives the first and second pressure rollers 31, 32, rotating the brush rollers 33 to clean the concrete adhering to the surface of the cutting wire 7. Simultaneously, the water inlet pipe 5 sprays water through the nozzle 51 to rinse the cutting wire 7, utilizing mechanical friction and water flow to perform the cleaning operation. After cleaning, the second clamping member is reset, ready for the next operation.

[0058] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
