Description

Technical Field

[0001] This invention belongs to the field of building material processing technology, specifically a building material cutting device. Background Technology

[0002] As the construction industry moves towards standardization and industrialization, traditional cutting equipment can no longer meet the needs of modern construction. Cutting materials such as stone, metal profiles, and concrete slabs is an essential part of construction projects. Currently, commonly used building material cutting equipment mainly includes circular saws, plasma cutters, and waterjet cutters. However, these devices still have many limitations in practical applications. Traditional circular saws rely on high-speed rotating saw blades for cutting. Although the equipment cost is low, it is difficult to balance cutting efficiency and precision. On the one hand, the saw blade is prone to wear during the cutting process and needs to be replaced frequently, leading to increased downtime. On the other hand, the saw blade is prone to generating large vibrations during cutting, resulting in uneven cut surfaces with dimensional errors of up to ±3mm, which is difficult to meet the strict precision standards of prefabricated buildings.

[0003] A cutting device for gypsum board building materials with mesh reinforcement, disclosed in CN118596367A, relates to the technical field of gypsum board cutting and processing equipment. This cutting device includes: a main support mechanism, a board placement support mechanism, a board cutting mechanism, and a cutting dust collection mechanism. The main support mechanism includes a base frame, a hydraulic cylinder, a connecting arm, and a U-shaped seat. The hydraulic cylinder is located inside the base frame and is mounted on an inner wall of the base frame. The bottom of the connecting arm is hinged to the output rod end of the hydraulic cylinder. The seat is located above the base frame, and its bottom is fixedly connected to the outer wall of the base frame. The board placement support mechanism includes a support frame, channel steel, a platform, and a connecting plate. The support frame is slidably positioned above the base frame. A material cutting device for construction sites, disclosed in CN109590548A, relates to the field of construction site technology. The cutting component of this invention can also perform chamfering operations on the material to be cut. During chamfering, the gripping and positioning component grips the material to be cut and tilts it according to the required chamfer angle, so that the chamfering cutting of the material can be achieved by the vertical downward cutting of the cutting component. The aforementioned gypsum board building material cutting equipment can recover dust generated during the cutting process. In the use of a construction site material cutting device, it reduces manual labor residue and can recover debris. Both structures aim to recover scraps from building materials, reducing hazards. However, in actual building material cutting operations, the impact of debris and dust is relatively small. There are no structural improvements for cutting various building materials. Instead, when cutting different shapes of various building materials, multiple different cutting materials need to be selected, and secondary grinding is required after cutting, which greatly affects the processing progress of building materials.

[0004] Therefore, a building material cutting device is proposed to address the above problems. Summary of the Invention

[0005] To address the problems mentioned in the background art, the present invention provides a building material cutting device with multiple different cutting modes, which can change the cutting state to complete the cutting of building materials of different shapes and sizes, making it more convenient to use. It also integrates grinding equipment into the cutting device, which allows for quick grinding operations after cutting.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a building material cutting device, including a limiting frame one, a limiting frame on one side of the limiting frame one, both the limiting frame one and the limiting frame two being L-shaped alloy frames, and the limiting frame one having an integrated cutting and grinding assembly inside; The integrated cutting and grinding assembly includes a rotating main frame that is rotatably configured with the limiting frame. A grinding roller is rotatably configured on one side of the rotating main frame, and a cutting motor is slidably configured on the other side of the rotating main frame. A cutting wheel is fixedly configured at the end of the main shaft of the cutting motor, and a deflection assembly is also configured on the outer side of the limiting frame. The deflection assembly includes a connecting plate that is fixed to the limiting frame by screws. A bogie is fixedly provided on the outer side of the connecting plate. A vertical frame is rotatably provided inside the bogie. A turntable is rotatably provided at the bottom end of the vertical frame. A base is fixedly provided at the bottom end of the turntable.

A lifting block is spirally provided on the outer side of the threaded shaft, and a bolt that is spirally provided with the cutting motor is provided through the outer side of the lifting block.

[0009] Preferably, the outer surface of the cutting motor housing is provided with a slot, and a guide plate that slides with the rotating main frame is inserted into the slot. Both ends of the guide plate are fitted with two bolts that spirally penetrate the rotating main frame.

[0010] Preferably, an insertion hole is provided on one side of the top of the rotating main frame, and a bolt three is spirally provided inside the insertion hole of the rotating main frame. A limiting shaft that is inserted into the rotating main frame is fixed at the bottom end of the bolt three.

[0011] Preferably, the front side of the limiting frame is fixedly provided with an insertion block, which aligns with the insertion hole after the rotating main frame rotates 90°.

[0012] Preferably, an adjusting long screw is spirally provided on the upper outer side of the first limiting frame and the outer side of the limiting frame, and a telescopic shaft is fixedly provided on the lower outer side of the first limiting frame and the outer side of the limiting frame.

[0013] Preferably, the vertical frame is internally fitted with four bolts that are helically connected to the bogie.

[0014] Preferably, a square frame is fixedly provided on the upper outer side of the connecting plate, a support leg is rotatably provided inside the square frame, a limiting plate is fixedly provided at the top of the support leg, and a groove corresponding to the limiting plate is opened inside the square frame.

[0015] Preferably, in S1, when cutting building materials, three cutting methods can be used. When the building board needs to be placed into the gap between the first limiting frame and the limiting frame for cutting, it can be kept in a vertical position and the cutting and grinding integrated component can be directly pushed to the outside of the building board, or the building board can be pushed between the first limiting frame and the limiting frame, and the cutting wheel can be driven by the cutting motor to perform the cutting operation. After the cutting is completed, the grinding roller can be driven by the driving motor to grind the building board. S2. If the building material is thick, the limiting frame can be unfolded by rotating the adjusting screw on the outside of the limiting frame and cooperating with the guide of the telescopic shaft to leave space for placement. S3. If the building material cannot be placed between the limiting frame one and the limiting frame for cutting, the main frame can be rotated to rotate the cutting wheel to the outside of the limiting frame one, and other blades can be replaced to perform cutting operations, avoiding the inability to complete various cutting operations due to the design of the cutting wheel. S4. If a horizontal cutting operation is required, the deflection component on the outside of the limiting frame can be rotated to open its base and support structure, forming a support structure to support the limiting frame and the limiting frame. Then, the building material can be placed in for horizontal cutting. The operation is simple and convenient, and there are multiple cutting modes. With the grinding component, the cutting and processing of building materials can be further accelerated.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention, through the rotating main frame structure design in the integrated cutting and grinding assembly, can change the cutting mechanism to vertical or horizontal by rotating the main frame in multiple directions. Combined with the integrated grinding roller structure design, it can provide grinding services for the cut building materials, making it more convenient to use and meeting the cutting needs of building materials of various sizes, thus accelerating the construction progress of building materials.

[0017] 2. The present invention uses a base in the deflection component in conjunction with a support structure, which can be rotated and opened to form a support structure to support the upper limiting frame and the integrated cutting and grinding component, and to meet the needs of horizontal cutting.

[0018] 3. The present invention uses a guide plate and bolt structure design to insert the guide plate into the slot of the cutting motor housing for positioning. With the help of the threaded shaft drive, the lifting block moves up and down, thereby driving the cutting motor to move up and down to complete the cutting operation. Attached Figure Description

[0024] like Figures 1 to 10 As shown, the present invention provides a building material cutting device, including a limiting frame 1, a limiting frame 2 on one side of the limiting frame 1, both the limiting frame 1 and the limiting frame 2 are L-shaped alloy frames. The symmetrical L-shaped alloy frame design of the limiting frame 1 and the limiting frame 2 can position the building material and reduce the problem of debris splashing. The limiting frame 1 is equipped with a cutting and grinding integrated component 3 inside. The integrated cutting and grinding assembly 3 includes a rotating main frame 31 that is rotatably mounted with the limiting frame 1. A grinding roller 315 is rotatably mounted on one side of the rotating main frame 31. The integrated grinding roller 315 structure can directly grind the surface of the building material. A cutting motor 32 is slidably mounted on the other side of the rotating main frame 31. A cutting wheel 33 is fixedly mounted at the end of the main shaft of the cutting motor 32. A deflection assembly 6 is also provided on the outside of the limiting frame 2. The deflection assembly 6 includes a connecting plate 61 that is fixed to the limiting frame 2 by screws. A steering frame 62 is fixedly provided on the outside of the connecting plate 61. A vertical frame 63 is rotatably provided inside the steering frame 62. A turntable 65 is rotatably provided at the bottom end of the vertical frame 63. A base 66 is fixedly provided at the bottom end of the turntable 65. Rotating the base 66 unfolds it and supports the cutting and grinding integrated assembly 3.

[0025] Specifically, a drive motor 34 is fixedly installed at the top of the limit frame 1, and the end of the main shaft of the drive motor 34 is fixedly installed with the grinding roller 315. The grinding roller 315 is made of abrasive wheel material to facilitate grinding of building materials. A servo motor 35 is fixedly installed on one side of the top of the rotating main frame 31. A threaded shaft 36 is fixedly installed at the end of the main shaft of the servo motor 35 and rotates with the rotating main frame 31. The threaded shaft 36 is driven to control the lifting block 37 to move up and down. The lifting block 37 is spirally installed on the outside of the threaded shaft 36. A bolt 38 spirally installed with the cutting motor 32 is passed through the outside of the lifting block 37. The lifting block 37 is installed on the outside of the cutting motor 32 using the bolt 38 for connection.

[0026] The outer surface of the cutting motor 32 has a slot 39. Inside the slot 39, a guide plate 310 is inserted and slidably disposed with the rotating main frame 31. Both ends of the guide plate 310 are fitted with bolts 311 that spirally penetrate the rotating main frame 31. Tightening the bolts 311 can press the guide plate 310 against the inside of the slot 39, guiding and positioning the cutting motor 32.

[0027] A socket is provided on one side of the top of the rotating main frame 31. A bolt 313 is spirally installed inside the socket of the rotating main frame 31. A limiting shaft 314 is fixed at the bottom of the bolt 313 and is inserted into the rotating main frame 31. The bolt 313 is inserted into the socket through the limiting shaft 314 to position the rotating main frame 31.

[0028] The front side of the limiting frame 1 is fixed with a plug 312, which is aligned with the plug hole after the rotating main frame 31 rotates 90°, so as to facilitate positioning after adjusting the orientation of the rotating main frame 31.

[0029] An adjusting screw 4 is spirally provided on the upper outer side of the first limiting frame 1 and the second limiting frame 2, and a telescopic shaft 5 is fixedly provided on the lower outer side of the first limiting frame 1 and the second limiting frame 2. Rotating the adjusting screw 4 controls the opening or closing distance of the first limiting frame 1 and the second limiting frame 2.

[0030] The interior of the vertical frame 63 is fitted with bolts 64 that are spirally arranged with the bogie 62. The bolts 64 are inserted into the interior of the bogie 62 for positioning.

[0031] A square frame 67 is fixedly installed on the upper outer side of the connecting plate 61. A support leg 68 is rotatably installed inside the square frame 67. A limiting plate 69 is fixedly installed at the top of the support leg 68. A groove corresponding to the limiting plate 69 is opened inside the square frame 67. After the support leg 68 is rotated and unfolded, the limiting plate 69 is inserted into the groove for positioning and to maintain the unfolded state for support.

[0032] S1. When cutting building materials, three cutting methods can be used. When the building board needs to be placed in the gap between the first limit frame 1 and the second limit frame 2 for cutting, it can be kept in a vertical position and the cutting and grinding integrated component 3 can be directly pushed to the outside of the building board, or the building board can be pushed between the first limit frame 1 and the second limit frame 2, and the cutting motor 32 drives the cutting wheel 33 to perform the cutting operation. After the cutting is completed, the grinding roller 315 is driven by the drive motor 34 to grind the building board. S2. If the building material is thick, the adjusting screw 4 on the outside of the limiting frame 1 and the limiting frame 2 can be rotated and guided by the telescopic shaft 5 to unfold the limiting frame 1 and the limiting frame 2 to make room for placement. S3. If the building material cannot be placed between the first limit frame 1 and the second limit frame 2 for cutting, the main frame 31 can be rotated to rotate the cutting wheel 33 to the outside of the first limit frame 1, and other blades can be replaced to perform cutting operations, avoiding the inability to complete various cutting operations due to the design of the cutting wheel 33. S4. For lateral cutting, the deflection component 6 on the outside of the second limiting frame 2 can be rotated to open its base and support structure, forming a support structure to support the first limiting frame 1 and the second limiting frame 2. The building material can then be placed inside for lateral cutting. The operation is simple and convenient, and multiple cutting modes are available. Combined with the grinding component, this further accelerates the cutting and processing of building materials. Among them, the cutting motor 32, the drive motor 34, and the servo motor 35 are existing technologies and will not be described in detail; at the same time, the present invention also includes power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail.

[0033] The wiring diagram of the motor in this invention is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the motor will not be explained in detail.

[0034] The working principle of the technical solution provided by this invention: Limiting frame 1 and limiting frame 2 form an L-shaped alloy frame structure, connected to the telescopic shaft 5 via an adjusting screw 4. Initially, the distance between them can be pre-adjusted according to the material dimensions. The telescopic shaft 5 provides horizontal guidance. When the adjusting screw 4 rotates, limiting frame 1 and limiting frame 2 can be simultaneously opened or tightened, forming a stable clamping space. Deflection assembly deployment: The connecting plate 61 of the deflection assembly 6 is fixed to limiting frame 2. The vertical frame 63 inside the steering frame 62 can be adjusted for tightness via bolt 4 64. Before use, if horizontal cutting is required, bolt 4 64 can be loosened, and the vertical frame 63 can be rotated to allow the turntable 65 to drive the base 66 to unfold horizontally. The support leg 68 rotates out from the square frame 67, and the limiting plate 69 engages with the bite groove for fixation, forming a stable support structure. The building material is placed vertically in the gap between the first limiting frame 1 and the second limiting frame 2. The material is clamped by adjusting the long screw 4 and the telescopic shaft 5 to ensure stability and prevent shaking during cutting. The cutting motor 32 drives the cutting wheel 33 to rotate at high speed. The operator pushes the rotating main frame 31 (or pushes the material) to make the cutting wheel 33 move along the material surface to complete the cutting. The cutting motor 32 is connected to the threaded shaft 36 through the lifting block 37. The servo motor 35 drives the threaded shaft 36 to rotate, which drives the lifting block 37 to move up and down along the rotating main frame 31, thereby adjusting the height of the cutting wheel 33 to adapt to materials of different thicknesses. After cutting, the drive motor 34 is started, which drives the grinding roller 315 to rotate. The grinding roller 315 and the rotating main frame 31... The rotating connection allows for grinding against the cutting surface, removing burrs and unevenness. The guide plate 310 is inserted into the slot 39 of the cutting motor 32 and fixed by bolt 311 to ensure component stability during cutting and grinding. When the material thickness exceeds the initial clamping range of the equipment, rotating the adjusting screw 4 causes the telescopic shaft 5 to extend synchronously, widening the distance between the first limit frame 1 and the second limit frame 2 until the material can be smoothly placed in. If a non-standard cutting wheel 33 is required (such as a special blade for special materials), bolt 313 can be loosened, the limit shaft 314 can be pulled out, and the rotating main frame 31 can be rotated 90° so that the cutting motor 32 rotates out to the outside of the first limit frame 1. At this time, the insert block 312 is inserted into the insertion hole of the rotating main frame 31 and... After fixing the new cutter with bolt 313, large materials that cannot be placed between the limiting frames can be edge-cut. Loosen bolt 64 in the deflection assembly 6, rotate the vertical frame 63 to make the base 66 land horizontally, and the support leg 68 rotates out from the square frame 67 and is locked into the bite groove by the limiting plate 69 to form a stable triangular support. Place the building material horizontally between the limiting frame 1 and the limiting frame 2, and adjust the long screw 4 to clamp the material. The cutting motor 32 drives the cutting wheel 33 to move horizontally to complete the horizontal cutting. The grinding roller 315 can also be used for surface treatment after horizontal cutting. The guide plate 310 cooperates with the slot 39 and the bolt 311 is tightened to prevent the cutting motor 32 from shaking when it is running at high speed.The limiting shaft 314 and the insert block 312 lock after the rotating main frame 31 rotates to prevent accidental rotation. The servo motor 35 controls the threaded shaft 36 to achieve electric lifting of the cutting wheel 33. The rotation of the support leg 68 of the deflection assembly 6 and the grooving structure allow for quick switching between vertical and horizontal modes.
