Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, and more specifically, to a building decoration cutting device. Background Technology

[0002] As a core sector for enhancing the functionality and aesthetic value of architectural spaces, the building decoration and renovation industry is seeing increasingly widespread application of decorative panels (such as bamboo fiberboard, gypsum board, and calcium silicate board) due to the popularization of prefabricated construction technology and consumers' increasing demands for precision in decoration. These applications have expanded from small residential interior wall cladding to mass-production decoration projects in large commercial complexes, hotels, office buildings, and other public buildings. As a core material for walls and ceilings, the installation quality of decorative panels directly determines the overall flatness, sealing, and lifespan of the building decoration.

[0003] Decorative panels (wall panels) are used in building interior decoration. These panels need to be cut during installation, currently primarily using small handheld cutting machines. The process involves measuring and drawing lines before cutting, and then cutting according to those lines. However, the high-speed operation of the equipment and other factors can easily cause deviations in the cutting trajectory, especially in long straight line cuts exceeding 1.2 meters, where the deviation is even greater, thus affecting the quality of the decoration. Therefore, we propose a new building decoration cutting device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a building decoration and finishing cutting device to solve the technical problem that deviations are easy to occur during cutting.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a building decoration and finishing cutting device, including an adjustment mechanism and a cutting mechanism and a positioning support mechanism provided on the adjustment mechanism. The adjustment mechanism includes a connecting plate and mounting plates provided at both ends of the connecting plate. A bidirectional lead screw is provided between the mounting plates. Moving blocks are symmetrically arranged on the bidirectional lead screw. The cutting mechanism includes a movable sleeve block movably arranged on the connecting plate. The positioning support mechanism includes a limiting rod symmetrically installed on the bottom surface of the moving block. A support rod is provided at the bend of the limiting rod. At least one end of the support rod is provided with a bend that bends upward at 90 degrees. A handle is provided laterally at the end of the bend.

[0006] Preferably, an adjusting handle is rotatably mounted on the side end of the mounting plate, and the adjusting handle is connected to the axis of the bidirectional lead screw.

[0007] Preferably, the upper end of the movable sleeve is provided with a threaded hole, and a threaded crank handle is installed in the threaded hole, the end of which contacts the connecting plate.

[0008] Preferably, the movable sleeve has symmetrical fixing rods on its front and back sides, the end of the fixing rod is connected to the cutting machine body, and the lower part of the fixing rod has a downward and outwardly curved guide rod, the guide rod and the blade of the cutting machine body are on the same straight line.

[0009] Preferably, the limiting rod includes a connecting part, which is bent into a U-shape, and the ends of the connecting part are connected to form a limiting part. The working surface of the limiting part is provided with a first ball bearing.

[0010] Preferably, the support rod includes a support part and a cleaning part along its long axis. The bottom surface of the support part is provided with a second ball bearing. The cleaning part is bent at ninety degrees and located at the end of the support part. The cleaning part is L-shaped and has bristles on its surface.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the design of a limiting rod structure, not only limits the overall device to fit the width of the decorative panel, but also converts the sliding friction between the limiting rod and the side of the decorative panel into rolling friction. The second ball bearing of the supporting rod supports the overall weight of the device. This double ball bearing design reduces resistance when the device moves on the decorative panel surface, making pushing easier and preventing blade "jumping" caused by device vibration, further ensuring the straightness of the cut. Even when cutting extra-long decorative panels, it maintains a stable movement trajectory. Combined with the quick-locking function of the threaded handle, the cutting position can be adjusted at any time to adapt to the cutting needs of different positions on the decorative panel. Cutting can be performed along a straight line by pushing, solving the problem of deviations that easily occur during current cutting methods.

[0012] 2. This utility model also features a support rod structure. The L-shaped cleaning part at the end of the support rod fits tightly against the surface of the decorative panel. The bristles at the bottom of the support rod can simultaneously clean up impurities such as wood chips and plaster chips generated during the cutting process, preventing debris accumulation from affecting the cutting line or scratching the surface of the decorative panel. This design can reduce the cleaning time of the decorative panel after cutting and effectively shorten the construction cycle in interior decoration projects. The bent part at the end of the support rod and the horizontal handle form a grip structure, making it convenient for construction personnel to push and operate. Attached Figure Description

Detailed Implementation

[0015] like Figures 1 to 5 As shown, the present invention relates to a building decoration and finishing cutting device, including an adjustment mechanism 100 and a cutting mechanism 200 and a positioning support mechanism 300 provided on the adjustment mechanism 100. The adjustment mechanism 100 includes a connecting plate 101 and mounting plates 102 provided at both ends of the connecting plate 101. A bidirectional lead screw 103 is provided between the mounting plates 102. Moving blocks 105 are symmetrically provided on the bidirectional lead screw 103. The cutting mechanism 200 includes a movable sleeve block 201 movably provided on the connecting plate 101. The positioning support mechanism 300 includes a limiting rod 301 symmetrically installed on the bottom surface of the moving block 105. A support rod 302 is provided at the bend of the limiting rod 301. At least one support rod 302 has a bent portion 3023 bent upward at ninety degrees at its end. A handle portion 3024 is provided laterally at the end of the bent portion 3023. This utility model reduces resistance and bumps by using the cooperation of the limiting rod 301 and the support rod 302 to ensure the straightness of the cut and avoid deviation. The pointing rod 205 assists in precise positioning, the cleaning part 3022 cleans up debris at the same time, and the handle part 3024 facilitates operation. It can improve cutting accuracy and decoration efficiency and is suitable for long straight cutting scenarios.

[0016] Specifically, an adjusting handle 104 is rotatably mounted on the side of the mounting plate 102, and the adjusting handle 104 is connected to the axis of the bidirectional lead screw 103. By rotating the adjusting handle 104, the bidirectional lead screw 103 can be easily driven to rotate, thereby causing the moving block 105 to move symmetrically closer to or further away from the bidirectional lead screw 103. This allows for quick adjustment of the spacing of the positioning support mechanism 300 according to the width of the decorative panel, adapting to the cutting needs of decorative panels of different specifications. The operation is convenient and the adjustment accuracy is high.

[0017] Furthermore, the upper end of the movable sleeve 201 is provided with a threaded hole, and a threaded crank 202 is threadedly installed in the threaded hole. The end of the threaded crank 202 contacts the connecting plate 101. When it is necessary to fix the position of the movable sleeve 201 on the connecting plate 101, the threaded crank 202 is rotated clockwise so that its end is tightly pressed against the connecting plate 101, and the movable sleeve 201 is fixed by friction. When it is necessary to adjust the position of the movable sleeve 201, the threaded crank 202 is rotated counterclockwise to release the pressure on the connecting plate 101, and the movable sleeve 201 can be pushed to slide along the connecting plate 101, which facilitates precise adjustment of the cutting position of the cutting mechanism 200 to meet the needs of different cutting positions.

[0018] It is worth noting that the movable sleeve 201 has symmetrically arranged fixing rods 203 on its front and back sides. The ends of the fixing rods 203 are connected to the cutting machine body 204. The lower part of the fixing rods 203 has a downward and outwardly curved guide rod 205. The guide rod 205 and the blade of the cutting machine body 204 are on the same straight line. The symmetrically arranged fixing rods 203 can provide stable support for the cutting machine body 204, preventing the cutting machine body 204 from shaking during high-speed cutting and ensuring cutting stability. The guide rod 205 is on the same straight line as the blade, which can be used to quickly align with the pre-drawn cutting line on the decorative panel before cutting, helping the operator to accurately position the cutting starting point and reduce cutting deviations caused by inaccurate positioning. Especially in long straight line cutting scenarios, it can effectively improve the accuracy of the cutting trajectory.

[0019] It is worth mentioning that the limiting rod 301 includes a connecting part 3011, which is bent into a U-shape. The ends of the connecting part 3011 are connected to form a limiting part 3012, and the working surface of the limiting part 3012 is provided with a first ball bearing 303. During operation, the limiting part 3012 closely fits the two sides of the decorative panel, providing lateral limiting for the decorative panel and preventing lateral displacement of the device during cutting. The first ball bearing 303 on the working surface of the limiting part 3012 can convert the sliding friction between the limiting part 3012 and the decorative panel into rolling friction, reducing the friction between the device and the decorative panel when the whole device moves. This not only makes it easier for the operator to push the device for cutting, but also avoids scratches on the side of the decorative panel due to friction, protecting the appearance quality of the decorative panel.

[0020] It is worth noting that the support rod 302 includes a support part 3021 and a cleaning part 3022 along its long axis. The two cleaning parts 3022 are staggered. The bottom surface of the support part 3021 is provided with a second ball bearing 304. The cleaning part 3022 is bent at ninety degrees and located at the end of the support part 3021. The cleaning part 3022 is L-shaped, and the ground surface of the cleaning part 3022 is provided with bristles 305. The second ball bearing 304 on the bottom surface of the support part 3021 supports the overall weight of the equipment, making the equipment move more smoothly and stably on the surface of the decorative panel, further reducing the cutting deviation caused by equipment bumps. The L-shaped cleaning part 3022 can fit against the surface of the decorative panel, and the bristles 305 at its bottom can simultaneously clean the cutting debris and dust on the surface of the decorative panel during the equipment's movement and cutting process, reducing the workload of cleaning the decorative panel after cutting and improving the efficiency of decoration construction.

[0021] Working Principle: This embodiment provides a building decoration cutting device. In use, the spacing of the positioning support mechanism 300 needs to be adjusted according to the width of the decorative panel to be cut. The operator rotates the adjusting handle 104 on the side of the mounting plate 102. Since the adjusting handle 104 is directly connected to the axis of the bidirectional lead screw 103, rotating the handle will cause the bidirectional lead screw 103 to rotate synchronously. The symmetrically arranged moving blocks 105 on the bidirectional lead screw 103, due to their threaded engagement with the lead screw, will move symmetrically closer or further away along the length of the connecting plate 101 when the lead screw rotates. This, in turn, causes the limiting rods 301 mounted on the bottom surface of the moving blocks 105 to move synchronously until the limiting rods 301 on both sides... The limiting part 3012 is aligned and adapted with both sides of the decorative panel. At this time, stop rotating the adjusting handle 104 to complete the width adaptation adjustment of the positioning support mechanism 300, ensuring that the equipment can be stably locked onto the decorative panel. Then, perform precise positioning of the cutting position: the operator first draws the cutting line on the surface of the decorative panel according to the cutting requirements, and then loosens the threaded handle 202 at the upper end of the movable sleeve 201 in the cutting mechanism 200 (rotate the threaded handle 202 counterclockwise to separate its end from the surface of the connecting plate 101, releasing the fixation of the movable sleeve 201), and pushes the movable sleeve 201 to slide along the connecting plate 101. During the process, observe the lower part of the fixing rods 203 on both sides of the movable sleeve 201. The guide rod 205 is bent downwards and outwards, and is aligned with the blade of the cutting machine body 204. When the end of the guide rod 205 is completely aligned with the cutting line on the decorative panel surface, the movable sleeve 201 is stopped from being pushed. Then, the threaded handle 202 is rotated clockwise, so that the end of the threaded handle 202 is tightly pressed against the surface of the connecting plate 101. The movable sleeve 201 is fixed to the connecting plate 101 by the self-locking of the threads and friction, thereby achieving precise alignment between the blade of the cutting machine body 204 and the cutting line, avoiding positional deviations in subsequent cutting. Then, the power to the cutting machine body 204 is turned on, and the blade rotates at high speed. At this time, the operator... The operator holds the handle 3024 at the end of at least one support rod 302 with both hands and slowly pushes the entire device forward. During the pushing process, the limiting part 3012 of the limiting rod 301 closely fits the two sides of the decorative panel through the first ball bearing 303 set on the working surface. The first ball bearing 303 converts the sliding friction between the limiting part 3012 and the side of the decorative panel into rolling friction, which not only limits the lateral deviation of the device during the cutting process, but also reduces the resistance of the device movement. At the same time, the second ball bearing 304 set on the bottom surface of the support part 3021 of the support rod 302 supports the overall weight of the device, so that the device remains stable when moving on the surface of the decorative panel and avoids the blade cutting trajectory deviation caused by the device bumping.As the equipment moves forward, the high-speed rotating cutting machine body 204 blades cut the decorative panel along a pre-aligned cutting line. Simultaneously, the L-shaped cleaning section 3022, bent at a 90-degree angle at the end of the support rod 302, moves with the equipment. Its bottom bristles 305 adhere to the surface of the decorative panel, cleaning away debris and dust generated during cutting, preventing debris accumulation from affecting cutting accuracy or subsequent cleaning. Throughout the cutting process, because the movable sleeve 201 is fixed to the connecting plate 101 via the threaded handle 202, the position of the cutting machine body 204 remains stable. Even in long, straight-line cutting scenarios, this ensures the blades always move along the cutting line, ultimately completing a precise and deviation-free decorative panel cutting operation.
