[0050] The present invention provides a cutting and forming equipment for the texture of artificial stone surface layer on building exterior walls, such as... Figure 1 As shown, it includes a cutting and forming section and an auxiliary shifting section 300, wherein:

[0051] Please refer to this carefully. Figures 2 to 7 The cutting and forming part includes a handle 100 and a cutting head 200.

[0053] Please refer to this carefully. Figure 17 The auxiliary displacement part 300 includes a body 310. The side of the body 310 is provided with a slot 320 that is open at one end and blocked at the other end. The side of the second outer shell 210 is provided with a locking strip 260 that matches the slot 320. The locking strip 260 can move within the slot 320, thereby using the auxiliary displacement part 300 to limit the cutting position and path of the cutting head 200.

[0054] The above structure helps construction workers to quickly create a surface texture that is uniform, straight, and consistent in depth, significantly improving the efficiency and quality of the surface texture forming work for building exterior walls.

[0055] In some embodiments, please refer to the following: Figure 8 and Figure 9 The first outer casing 110 is provided with a plurality of first partitions 101, which divide the first outer casing 110 into a plurality of first chambers. The circuit board 120 and the motor 130 are respectively disposed in different first chambers and connected by wires. The first partitions 101 facilitate the installation and fixation of each component and avoid mutual interference between the components. Similarly, the second outer casing 210 can also be divided into the same partitions, which will not be described in detail here.

[0056] In some embodiments, please refer to Figure 8 and Figure 9 The first housing 110 is also provided with a built-in battery 160, which is located in the first cavity at the bottom of the first housing 110 and is used to power the circuit board 120; the bottom of the first housing 110 is also provided with a charging interface 161 corresponding to the built-in battery 160.

[0057] In some embodiments, please refer to the following: Figure 2 and Figure 9 The outer side of the first housing 110 is also provided with a power indicator light 170 for indicating the remaining power of the built-in battery 160.

[0058] Specifically, in this embodiment, the first outer shell 110 has a right-angled shape and a rectangular cross-section, which facilitates hand gripping. A switch 140 and a control button 150 are embedded on the front outer surface of the first outer shell 110, and a power indicator light 170 is embedded on the rear outer surface of the first outer shell 110. The switch 140 controls the activation and deactivation of the entire device, the control button 150 controls the device's operating status, and the power indicator light 170 indicates the device's power level by displaying different colors. A control chip 121 mounted on the circuit board 120 drives the motor 130 to rotate. The circuit board 120, the built-in battery 160, and the motor 130 are all placed in an independent first chamber and remain stable during device operation. The switch 140, control button 150, power indicator light 170, built-in battery 160, and motor 130 are all connected to the circuit board 120 via several wires to form a circuit.

[0059] In some embodiments, please refer to the following: Figures 2 to 5 The upper surface of the second outer shell 210 is provided with a first groove 211, and a removable transparent plate 212 is provided in the first groove 211; the lower surface of the second outer shell 210 is provided with a second groove 213, and a removable dust baffle 214 is provided in the second groove 213; a removable protective cover 215 is provided on the side of the second outer shell 210 near the surface to be cut. Specifically, the cross-sectional shape of the second outer shell 210 is U-shaped, wherein each of the two opposite concave front surfaces is provided with an opening, and the cutting blade 240 extends from the opening to contact the surface to be cut and complete the cutting. The overall shape of the protective cover 215 is a hollow cuboid with one open side, and its open side can be fixed to the front side of the second outer shell 210 and cover and protect all the displacement components 250 and cutting components 240 exposed outside the second outer shell 210. The upper and lower surfaces of the second outer casing 210 have continuous first grooves 211 and second grooves 213 at their concave boundaries, respectively, for embedding a transparent plate 212 for easy observation and a dust baffle 214 for easy replacement. In this embodiment, the transparent plate 212 can be made of rectangular transparent glass (such as high-strength tempered glass), acrylic sheet, etc., with each side fixed in the first groove 211 and able to be pulled out from the first groove 211 for easy cleaning or replacement of the transparent plate 212, while preventing the transparent plate 212 from breaking during equipment use. The dust baffle 214 has a rectangular cross-sectional shape, with each side fixed in the second groove 213 and able to be pulled out from the second groove 213 for easy removal of dust and other debris from the dust baffle 214.

[0060] In some embodiments, both the first housing 110 and the second housing 210 can be disassembled to facilitate the repair or replacement of internal components. All edges and corners of the first housing 110 are rounded, and the outer surface of the first housing 110 is roughened to facilitate gripping by construction personnel.

[0061] In some embodiments, please refer to the following: Figure 10 The drive shaft 220 and the main shaft 230 are respectively installed in the second housing 210 through bearings 221. The output end of the motor 130, both ends of the drive shaft 220 and the end of the main shaft 230 are respectively provided with bevel gears 222 that mesh in sequence. In this embodiment, the second housing 210 is provided with several bearing seats at the positions where the drive shaft 220 and the main shaft 230 are installed. Multiple (two in this embodiment) drive shafts 220 mesh sequentially to achieve power transmission and direction change. Each drive shaft 220 is a rod with a circular cross-section. A bearing 221 is fixed at a certain distance from the end of each drive shaft 220. Each bearing 221 is fixed on a bearing seat. A bevel gear 222 is fixed at both ends of each drive shaft 220. The two bevel gears 222 mesh and transmit power between the two drive shafts 220. The main shaft 230 has a circular cross-section. The two ends of the main shaft 230 are fixed inside the second housing 210 by bearings 221 and bearing seats, respectively. The middle section of the main shaft 230 is located in the concave space of the second housing 210.

[0062] In some embodiments, please refer to the following: Figure 15a and Figure 15b and combined Figures 10 to 13 The main shaft 230 includes a main rod 231 and a secondary rod 232, both of which are cylindrical. The main rod 231 includes a smooth section 233 and a threaded section 234. Specifically, one end of the main rod 231 is a smooth section 233 of a certain length, and the surface of the remaining length is threaded, i.e., the threaded section 234. The diameter of the smooth section 233 of the main rod 231 is slightly larger than the outer diameter of the threaded section 234. The secondary rod 232 is hollow and has one open end and the other closed end. The length of the auxiliary rod 232 is equal to the length of the smooth section 233 of the main rod 231. The outer diameter of the auxiliary rod 232 is equal to the diameter of the smooth section 233 of the main rod 231. The inner wall of the auxiliary rod 232 is provided with an internal thread that matches the external thread of the main rod 231. The auxiliary rod 232 can be fitted into the threaded section 234 and screwed onto the threaded section 234, realizing a tight connection between the auxiliary rod 232 and the end of the threaded section 234 of the main rod 231, forming a threaded rod in the middle for mounting the cutting blade 240. Please refer to this carefully. Figure 16The cutting blade 240 is circular, and its center (center) has a threaded hole that matches the threaded section 234. Each cutting blade 240 is threadedly fastened to the main shaft 230 and evenly distributed on the threaded rod in the center of the main shaft 230. A spacer 235 is also provided between every two cutting blades 240. Several spacers 235 are also threadedly fastened to the main shaft 230, with each spacer 235 located between and in close contact with the cutting blades 240 to prevent the cutting blades 240 from shifting during cutting. In some embodiments, the spacing between the cutting blades 240 can be adjusted by changing the width of the spacers 235 or by increasing or decreasing the number of spacers 235. Since the cutting blades 240 are threadedly connected to the main shaft 230, the cutting blades 240 can be repaired or replaced.

[0063] In some embodiments, please refer to the following: Figure 4 The shifting components 250 are four in number, located at the four corners of the cutting head 200 near the surface to be cut. Please refer to the following for details. Figure 11 , 12 14. The surfaces of the second outer shell 210 corresponding to the four displacement components 250 are respectively recessed to form arched grooves 252. The directional wheels 251 are respectively fixed to the bottom of the arched grooves 252 by retractable connectors 253. When the directional wheel 251 is in contact with the surface to be cut and the connector 253 is not under pressure, the cutting blade 240 does not touch the surface to be cut. When the connector 253 is compressed and retracted, the cutting blade 240 cuts into the surface to be cut. Specifically, the displacement components 250 are all located on two surfaces on the front side of the second outer shell 210. The directional wheel 251 is connected to the front end of the connector 253 and can rotate in a direction. The rear end of the connector 253 is fixed to the bottom of the arched groove 252 by a nut. The connector 253 will shrink and deform to a certain extent after being subjected to pressure, and will recover its deformation after the pressure is removed. It should be noted that there needs to be a certain amount of friction between the directional wheel 251 of the shifting component 250 and the surface to be cut, so as to ensure that the equipment moves only along the directional direction and does not deviate in other directions during operation.

[0064] In some embodiments, please refer to the following: Figure 17 The body 310 is also provided with a handle 330 and a verticality gauge 340, which are both located on an adjacent surface of the surface where the slot 320 is located. In this embodiment, the cross-sectional shape of the body 310 is rectangular, and a slot 320 is provided on the right side of the body 310. The slot 320 is vertically continuous and has an open top and a closed bottom. The handle 330 and the verticality gauge 340 are both located at the rear of the body 310.

[0065] After the locking strip 260 is inserted into the slot 320, the cutting and forming part and the auxiliary shifting part 300 remain in close contact. The locking strip 260 can move up and down within the slot 320, thereby allowing relative movement between the cutting and forming part and the auxiliary shifting part 300 of the equipment. As the connecting piece 253 of the shifting component expands and contracts, the locking strip 260 can shift back and forth within the slot 320. Of course, the front of the body 310 should have a certain degree of roughness to ensure that the auxiliary shifting part 300 remains relatively stable with the surface to be cut during the operation of the equipment, preventing accidental shifting or misalignment.

[0066] In addition, to reduce the overall weight of the equipment and facilitate operation by construction personnel, the protective components such as the outer shell (including the first outer shell 110 and the second outer shell 210), partitions, and body 310 can be made of ABS plastic, while the mechanical transmission and cutting components such as the bearing seats, drive shaft 220, bearings 221, gears, main shaft 230, cutting blades 240, and pads 235 can be made of lightweight alloy steel.

[0067] This invention also provides a method for cutting and shaping the texture of artificial stone surface layer on building exterior walls, using the aforementioned equipment for cutting and shaping the texture of artificial stone surface layer on building exterior walls, and including the following steps:

[0068] Step 1: Turn on switch 140 and check the device's battery level. If the power indicator light 170 shows low battery, charge the device first to ensure it has sufficient power.

[0069] Step 2: Remove the protective cover 215, check whether the shifting assembly 250, the cutting blade 240 and other components are intact, and whether the connection between the cutting blade 240 and the spindle 230 is tight. Then press the control button 150 to check whether the cutting blade 240 is operating normally.

[0070] Step 3: Perform a trial cut on a localized area of ​​the surface to be cut, so that the cutting blade 240 can smoothly cut a texture of a certain depth on the surface of the artificial stone.

[0071] Step 4: Place the auxiliary displacement part 300 in one corner of the surface to be cut, such as the upper right corner, so that the rough surface of the body 310 is in contact with the surface to be cut, and the slot 320 is located on the right side of the auxiliary displacement part 300 with one end of the opening facing upward. Adjust the auxiliary displacement part 300 with the help of the verticality gauge 340 to keep the auxiliary displacement part 300 in a vertical state.

[0072] Step 5: Hold the handle 330 of the auxiliary shifting part 300 with your left hand and press the auxiliary shifting part 300 against the surface to be cut to ensure that the auxiliary shifting part 300 does not shift; hold the handle 100 of the cutting forming part with your right hand, insert the retaining strip 260 on the side of the cutting head 200 into the opening end of the slot 320 of the auxiliary shifting part 300, and make the directional wheels 251 of all the shifting components 250 of the cutting forming part contact the surface to be cut.

[0073] Step 6: Press and hold the control button 150 to make the cutting blade 240 rotate, and apply pressure perpendicular to the surface to be cut to the cutting forming part, so that the connecting parts 253 of each displacement component 250 are simultaneously compressed and contracted, and each cutting blade 240 cuts the same depth on the surface to be cut.

[0074] Step 7: Press down the auxiliary shifting part 300 with your left hand, hold the cutting and forming part with your right hand, press the control button 150 and maintain the pressure on the cutting and forming part, and then move the cutting and forming part downward at a certain speed until the card strip 260 abuts against the lower closed end of the card slot 320.

[0075] Step 8: Release the control button 150, maintain the pressure on the cutting and forming part to ensure that the cutting and forming part does not shift, and then move the auxiliary shifting part 300 downward until the card strip 260 moves to the opening end of the card slot 320, and the card strip 260 must not be dislodged from the card slot 320.

[0076] Step 9: Repeat steps 7 to 8 until the device reaches the other side (lower) boundary of the surface to be cut.

[0077] Step 10: Reposition the device back to the upper boundary of the surface to be cut, and shift the device to the left a certain distance from its previous position. Again, use the verticality gauge 340 to ensure that the entire device is vertical.

[0078] Step 11: Repeat steps 6 to 10, cutting from top to bottom and from right to left, until the texture of the surface to be cut is formed.

[0079] It should be noted that in step 10, if the spacing of the cutting blades 240 of the device can meet the design requirements of the spacing of the surface texture of the fake stone, that is, the two are equal in size, then when the device moves to the left, it is only necessary to control the rightmost cutting blade 240 to be just embedded in the leftmost texture; if the design spacing of the surface texture of the fake stone is too small, and it is not possible to directly adjust the spacing of the cutting blades 240 to the same size as the spacing of the surface texture, then the spacing of the cutting blades 240 should be controlled to be a certain integer multiple of the spacing of the surface texture. First, the entire surface layer is cut according to the aforementioned method. Then, based on the formed texture, the surface layer between each texture is cut in sequence by moving the device to the left. The distance of the device offset once is the spacing of the surface texture. A ruler and charcoal pencil can be used to mark the position to assist in positioning.

[0080] In addition, during the actual construction of engineering projects, if the area of ​​the artificial stone surface of the building exterior wall to be cut is large or there are problems such as columns, waistlines, door and window openings, the surface to be cut can be divided into several zones according to the specific situation, and then the construction work can be carried out in each zone in sequence or simultaneously according to the above steps.

[0081] In summary, the present invention provides a cutting and forming device and method for creating artificial stone surface texture on building exterior walls. The device includes a cutting and forming section and an auxiliary shifting section 300. The cutting and forming section includes a handle 100 and a cutting head 200.
