[0060] In some embodiments, the first shell 110 and the second shell 210 can be disassembled to facilitate the repair or replacement of internal components. The edges and corners of the outside of the first shell 110 are rounded, and the outer surface of the first shell 110 is roughened to facilitate the grip of construction workers.

[0061] In some embodiments, please refer to Fig.10 The transmission shaft 220 and the main shaft 230 are respectively installed in the second housing 210 through bearings 221, and the output end of the motor 130, the two ends of the transmission 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 a plurality of bearing seats at the position for mounting the transmission shaft 220 and the main shaft 230. A plurality of (two in this embodiment) transmission shafts 220 are meshed in sequence to realize power transmission and direction change. Each transmission shaft 220 is a rod with a circular cross-section. A bearing 221 is fixed at both ends of each transmission shaft 220 at a certain distance from the end. Each bearing 221 is fixed on each bearing seat. A bevel gear 222 is fixed at both end heads of each transmission shaft 220. The two bevel gears 222 between the two transmission shafts 220 are meshed for transmission. The cross-sectional shape of the main shaft 230 is circular. The two ends of the main shaft 230 are respectively fixed to the inside of the second housing 210 by bearings 221 and bearing seats. 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 Fig.15a and Fig.15b , and combined with Figures 10 to 13 The main shaft 230 includes a main rod 231 and a secondary rod 232. The main rod 231 and the secondary rod 232 are both cylindrical in shape. 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 portion is provided with threads, 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 an open end and a closed end. The secondary rod 23 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, and the inner wall of the auxiliary rod 232 is provided with an internal thread matching the external thread of the main rod 231. The auxiliary rod 232 can be inserted into the threaded section 234 and screwed with the threaded section 234 to achieve a fastening 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 installing the cutting blade 240. Please refer to Fig.16The cutting blade 240 is circular, and a threaded hole matching the threaded section 234 is provided in the middle (center) of the cutting blade 240. Each cutting blade 240 can be fastened to the main shaft 230 through a thread and evenly arranged on the threaded rod in the middle of the main shaft 230. A pad 235 is also provided between each two cutting blades 240. Several pads 235 are also fastened to the main shaft 230 through a thread. Each pad 235 is respectively located between each cutting blade 240 and fits closely with the cutting blade 240 to prevent the cutting blade 240 from shifting during the cutting process. In some embodiments, the spacing between the cutting blades 240 can also be adjusted by changing the width of the pad 235 or increasing or decreasing the number of the pads 235. Since the cutting blade 240 is threadedly connected to the main shaft 230, the cutting blade 240 can be repaired or replaced.

[0063] In some embodiments, please refer to Figure 4 There are four displacement components 250, which are respectively located at the four corners of the cutting head 200 close to the surface to be cut. Fig.11 , 12 and 14, the surfaces of the second housing 210 corresponding to the four shifting assemblies 250 are respectively concave inward to form an arch groove 252, and the directional wheels 251 are respectively fixed to the bottom of the arch groove 252 through retractable connectors 253; when the directional wheels 251 are 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 shifting assemblies 250 are all located on the two surfaces on the front side of the second housing 210, the directional wheels 251 are connected to the front end of the connector 253 and can be directional and rotatable, and the rear end of the connector 253 is fixed to the bottom of the arch groove 252 through a nut, and the connector 253 will shrink and deform to a certain extent after being under pressure, and will recover after the pressure is removed. It should be noted that there needs to be a certain friction between the directional wheel 251 of the shifting assembly 250 and the surface to be cut to ensure that the device only moves in a directional direction without deviation in other directions when in operation.

[0064] In some embodiments, please refer to Fig.17 The body 310 is also provided with a handle 330 and a verticality meter panel 340, which are disposed on a surface adjacent to the surface of the body 310 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 through-through and has an open upper end and a closed lower end. The handle 330 and the verticality meter panel 340 are disposed on the back of the body 310.

[0065] When the clamping strip 260 is inserted into the clamping slot 320, the cutting and forming part and the auxiliary displacement part 300 always keep close contact, and the clamping strip 260 can move up and down in the clamping slot 320, so that the cutting and forming part and the auxiliary displacement part 300 of the equipment can move relative to each other; with the expansion and contraction deformation of the connecting member 253 of the displacement assembly, the clamping strip 260 can shift forward and backward in the clamping slot 320. Of course, the front of the body 310 should have a certain degree of roughness to ensure that the auxiliary displacement part 300 and the surface to be cut remain relatively stable when the construction personnel use the equipment, and no accidental shift or dislocation occurs.

[0066] In addition, in order to reduce the overall weight of the equipment and facilitate operation by construction personnel, the equipment's outer shell (including the first outer shell 110 and the second outer shell 210), partitions, body 310 and other enclosure parts can be made of ABS plastic, and the equipment's bearing seat, transmission shaft 220, bearings 221, gears, main shaft 230, cutting blade 240, pad 235 and other parts that play a mechanical transmission and cutting role can be made of lightweight alloy steel.

[0067] The present invention also provides a method for cutting and molding a texture of a building exterior wall artificial stone surface layer, using the above-mentioned building exterior wall artificial stone surface layer texture cutting and molding equipment, comprising the following steps:

[0068] Step 1: Turn on the switch 140 and check the power status of the device. If the power indicator light 170 shows that the power is low, charging is required to ensure that the device has sufficient power.

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

[0070] Step 3: Perform a trial cut at a local position of the surface to be cut, so that the cutting blade 240 can normally and smoothly cut a texture of a certain depth on the artificial stone surface layer.

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

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

[0073] Step 6: Press and hold the control button 150 to put the cutting blade 240 into a rotating state, and apply pressure perpendicular to the surface to be cut to the cutting forming part, so that the connecting parts 253 of each shifting assembly 250 are compressed and contracted at the same time, and each cutting blade 240 cuts the same depth on the surface to be cut.

[0074] Step 7: Press the auxiliary displacement 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 constant speed until the card strip 260 contacts 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 displacement part 300 downward until the card strip 260 moves to the open end of the card slot 320 , and the card strip 260 must not fall out of the card slot 320 .

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

[0077] Step 10: Reposition the device to the upper boundary of the surface to be cut, and shift the device to the left by a certain distance compared to the previous position, and use the verticality instrument panel 340 again to ensure that the entire device is in a vertical state.

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

[0079] It should be noted that in step 10, if the spacing of the cutting blades 240 of the equipment can meet the design requirements of the spacing of the artificial stone surface texture, that is, the two are equal in size, then when the equipment moves to the left, it is only necessary to control the rightmost cutting blade 240 to just embed into the leftmost texture; if the design spacing of the artificial stone surface texture is too small, and the spacing of the cutting blades 240 cannot be directly adjusted 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, and then, based on the formed texture, the surface layer between each texture is supplemented by moving the equipment to the left in turn. The distance the equipment is offset at one time is the spacing of the surface texture, and markings can be made with the help of tools such as rulers and charcoal pencils to assist positioning.

[0080] In addition, in the actual construction process of the project, if the area of ​​the artificial stone surface layer of the building exterior wall to be cut is large or there are local problems such as columns, waistlines, door and window openings, etc., the surface layer to be cut can be planned into several partitions according to the specific situation, and then the construction work can be carried out in each partition in sequence or simultaneously according to the above steps.
