Description

Technical Field

[0001] The invention relates to the technical field of wallboard processing, and in particular to a sawing and grooving process and a device for an SPC wallboard. Background Art

[0002] SPC wall panels are a new type of environmentally friendly decorative material that combines the advantages of natural stone powder and polymer materials and is widely used in interior wall decoration. After the wall panels are processed, they usually need to be slotted for easy installation. However, in order to improve the softness and modernity of the space, current wall decoration uses a lot of rounded corners, which puts forward the process requirements of arc slotting for wall panel processing. However, the existing mainstream slotting equipment is mainly suitable for straight line slot processing, and manual intervention is still required when encountering arc segment processing. However, manual operation is difficult to ensure processing consistency, which can easily lead to fluctuations in accuracy and unstable quality of finished products.

[0003] To this end, a Chinese patent application with publication number CN118596361A discloses a CNC grooving machine for wall panel processing, which places the wall panel body on the top of the supporting platform, and the second electric telescopic rod works to drive the clamping plate to move down and press the wall panel body to position it, thereby ensuring the stability and accuracy of the grooving. The rotating motor and the first electric telescopic rod work, the rotating motor drives the grooving drill bit to rotate, and the first electric telescopic rod drives the support to move down, so that the rotating grooving drill bit drills the top of the wall panel body, and then the driving motor works, and the circular gear and the sleeve gear ring are meshed to drive the transposition disk to rotate, and then the grooving drill bit slowly moves in a circular motion to open an arc groove. Since the second guide rod can slide in the limiting slide groove of the first guide rod, the length of the telescopic assembly can be adjusted, and then the spacing between the clamping plates on both sides can be adjusted, so that it can fix wall panel bodies of different lengths, and the positioning effect is better.

[0004] In arc groove processing scenarios, process requirements often need to strictly follow preset radius parameters, especially for arc grooves with high precision requirements, the dimensional tolerance control is more stringent. The technical limitations of current traditional equipment are reflected in two aspects: first, some equipment adopts a fixed processing radius design, which can only adapt to a single arc specification, and its versatility is severely limited; second, the equipment that relies on the dynamic coordinated control of the X-axis and Y-axis moving speeds to achieve arc processing has a certain radius adjustment capability, but when switching between different specifications, it needs to be adjusted through complex parameter trial and error, and the operator needs to repeatedly calibrate the speed ratio and path trajectory. This technical path leads to two core defects: on the one hand, the radius adjustment cannot be completed directly through automatic parameter input, and the process adaptability is insufficient; on the other hand, the debugging process significantly increases non-processing time, resulting in a loss of processing efficiency, and the parameter matching error under manual intervention is prone to fluctuations in the size of the finished product, forming a dual technical shortcoming of precision assurance and efficiency improvement.

When processing straight grooves, the mounting seat and the movable seat are driven to move respectively by two adjustment mechanisms, and then the milling cutter on the movable seat is used to perform slotting.

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figure 1-Figure 3 A sawing and grooving device for SPC wall panels comprises a workbench 1, an adjusting mechanism 2 and a connecting mechanism 3; a mounting seat 11 and a movable seat 12 are arranged on the workbench 1, two adjusting mechanisms 2 are arranged, and the two adjusting mechanisms 2 are respectively connected to the mounting seat 11 and the movable seat 12 through the connecting mechanism 3; a rotating seat 111 is rotatably arranged on the mounting seat 11, and an adjusting component 13 for adjusting the distance between the movable seat 12 and the rotating seat 111 is arranged on the rotating seat 111; a milling cutter 121 for grooving processing is arranged on the movable seat 12; a rotating drive component 14 for controlling the rotation of the rotating seat 111 is arranged on the mounting seat 11.

[0032] The present invention realizes the function of quickly and accurately adjusting the processing radius when processing arc grooves through the workbench 1, the adjustment mechanism 2 and the connecting mechanism 3, and solves the problem that the traditional slotting equipment cannot process arc grooves of different sizes. The movable seat 12 is provided with an electric push rod for controlling the lifting and lowering of the milling cutter 121 in the vertical direction and a servo motor for controlling the rotation of the milling cutter 121. The workbench 1 is provided with a controller for human-computer interaction, and the electric push rod and the servo motor are electrically connected to the controller. The workbench 1 is provided with a clamp for fixing the plate 312 material. When processing a straight groove, the two adjustment mechanisms 2 drive the mounting seat 11 and the movable seat 12 to move respectively through the connecting mechanism 3, and make the mounting seat 11 and the movable seat 12 move synchronously in the horizontal direction, and then send a signal to the electric push rod and the servo motor through the controller, and the electric push rod and the servo motor drive the milling cutter 121 to move down and rotate respectively, and then the high-speed rotating milling cutter 121 is used for slotting. When processing the arc groove, first disconnect the connection between the adjustment mechanism 2 and the mounting seat 11 through the connection mechanism 3. At this time, the mounting seat 11 is in a free state, and the movable seat 12 is connected to the adjustment mechanism 2. The position of the movable seat 12 is fixed by the adjustment mechanism 2. Then, the distance between the mounting seat 11 and the movable seat 12 is adjusted by the adjustment component 13, and then the distance between the movable seat 12 and the rotating seat 111 is adjusted to complete the adjustment of the processing radius. Then, the connection mechanism 3 is controlled to connect the adjustment mechanism 2 and the mounting seat 11, and the connection between the movable seat 12 and the adjustment mechanism 2 is disconnected. Then, the rotating seat 111 is driven to rotate by the rotation drive component 14, and the rotating seat 111 drives the movable seat 12 to rotate through the adjustment component 13, and then the arc groove is processed. By controlling the connection mechanism 3, it is possible to quickly switch between the straight groove and the arc groove during the processing process, and the processing radius of the arc groove can be quickly adjusted.

[0033] Reference Figure 1 and Figure 3 : The adjusting mechanism 2 includes two first brackets 21 and two linear drive components 22, and the two linear drive components 22 are used to drive the two first brackets 21 to translate through the connecting mechanism 3; a straight groove is opened on the first bracket 21, and the extension directions of the straight grooves of the two first brackets 21 are perpendicular to each other; the mounting seat 11 and the movable seat 12 are respectively slidably matched with the straight grooves of the first brackets 21 of the two adjusting mechanisms 2.

[0034] The present invention realizes the function of controlling the precise movement of the mounting seat 11 and the movable seat 12 through the first bracket 21 and the linear drive assembly 22. And in cooperation with the control of the connecting mechanism 3, when the first bracket 21 is connected to the linear drive assembly 22 through the connecting mechanism 3, if the linear drive assembly 22 stops driving, the position of the first bracket 21 can be locked by the linear drive assembly 22, and then the positioning of the mounting seat 11 or the movable seat 12 is completed. When the connecting mechanism 3 disconnects the first bracket 21 from the linear drive assembly 22, the first bracket 21 only plays a supporting role and will not affect the movement of the parts that slide with the first bracket 21. Guide rails are provided on the sides of the workbench 1, and the first bracket 21 slides with the guide rails. The mounting seat 11 or the movable seat 12 is controlled to move in the horizontal direction by two mutually perpendicular first brackets 21, thereby completing the precise positioning of the mounting seat 11 and the movable seat 12. When processing the arc groove, the operator disconnects the first bracket 21 that is slidably matched with the mounting seat 11 from the linear drive assembly 22 through the connecting mechanism 3. The connecting mechanism 3 connects the adjusting mechanism 2 and the movable seat 12. At this time, the linear drive assembly 22 of the adjusting mechanism 2 that is transmission-connected to the movable seat 12 stops driving, and the first bracket 21 is fixed by the linear drive assembly 22, and then the processing radius of the arc groove is adjusted by the adjusting assembly 13. Then, the connection state is switched through the connecting mechanism 3, and then the rotating seat 111 is driven to rotate by the rotating drive assembly 14 to process the arc groove. When processing the straight groove, the connecting mechanism 3 is controlled to control the adjusting mechanism 2 to be transmission-connected with the movable seat 12, and then the linear drive assembly 22 is used to control the movement of the two first brackets 21 to accurately adjust the position of the movable seat 12, and the straight groove is processed by the milling cutter 121 on the movable seat 12.

[0035] Reference Figure 3-Figure 6 : The linear drive assembly 22 includes a first screw 221 rotatably arranged on the workbench 1 and a first rotary driver 222 for driving the first screw 221 to rotate; the connecting mechanism 3 includes a first support 31 and a limiting assembly 32; the first support 31 is arranged on the first bracket 21, and a threaded sleeve 311 threadedly connected to the first screw 221 is rotatably arranged on the first support 31; the limiting assembly 32 is used to limit the rotation of the threaded sleeve 311.

[0036] The present invention realizes the function of controlling the connection between the linear drive assembly 22 and the first bracket 21 through the first screw 221, the first rotation driver 222, the first support 31 and the limiting assembly 32. When the limiting assembly 32 limits the rotation of the threaded sleeve 311, the first rotation driver 222 drives the first screw 221 to rotate, the first screw 221 drives the threaded sleeve 311 threadedly connected thereto to move, and the threaded sleeve 311 drives the first support 31 and the first bracket 21 to move, thereby achieving the effect of adjusting the movement of the mounting seat 11 or the movable seat 12. When the limiting assembly 32 releases the rotation restriction of the threaded sleeve 311, the adjusting assembly 13 controls the movement of the mounting seat 11, the mounting seat 11 will push the first bracket 21 to move, and the first bracket 21 drives the first support 31 and the threaded sleeve 311 to move, and the threaded sleeve 311 will rotate in the corresponding direction when it moves relative to the first screw 221, so as to prevent the first screw 221 from affecting the movement of the first bracket 21. The first rotation driver 222 is preferably a servo motor, and the first rotation driver 222 is electrically connected to the controller. The first screw 221 is a ball screw. Through the transition of the ball, it is prevented that when the first bracket 21 drives the first support 31 and the threaded sleeve 311 to move, the friction between the threaded sleeve 311 and the first screw 221 is too large, which affects the service life of the parts. In the working state, when the arc groove is opened, the rotation restriction of the threaded sleeve 311 on the first bracket 21 matched with the mounting seat 11 is first released through the restriction component 32, and at this time, the first bracket 21 matched with the movable seat 12 is still connected to the linear drive component 22, so the movement of the movable seat 12 is restricted by the linear drive component 22. Then, the spacing between the mounting seat 11 and the movable seat 12 is increased by the adjustment component 13, and the movement of the movable seat 12 is restricted, so the mounting seat 11 moves under the drive of the adjustment component 13 to complete the adjustment of the processing radius of the arc groove.

[0037] Reference Figure 1 and Figure 2 The adjusting assembly 13 includes a second screw rod 132 and a second rotation driver 131 for driving the second screw rod 132 to rotate; the second screw rod 132 is rotatably arranged on the rotating seat 111, and the second screw rod 132 is threadedly connected to the movable seat 12, and the second rotation driver 131 is arranged on the rotating seat 111; a second bracket 15[1] is movably arranged on the workbench 1, a second support 151 is slidably mounted on the second bracket 15, and the second screw rod 132 is rotatably connected to the second support 151.

[0038] The present invention realizes the function of adjusting the distance between the mounting seat 11 and the movable seat 12 through the second rotary driver 131, the second screw 132, the second bracket 15 and the second support 151. The second rotary driver 131 is preferably a servo motor, and the second rotary driver 131 is electrically connected to the controller. An arc guide groove is provided on the second bracket 15, and the second support 151 is slidably matched with the arc guide groove. The distance between the second support 151 and the rotating seat 111 is fixed, and the two ends of the second screw 132 are supported by the second support 151 and the rotating seat 111 respectively. When adjusting the processing radius of the arc groove, the connection between the movable seat 12 and the adjustment mechanism 2 is disconnected, and the transmission connection between the connecting mechanism 3 and the movable seat 12 is maintained. Then, a signal is sent to the second rotation driver 131 through the controller. After receiving the signal, the second rotation driver 131 drives the second screw 132 to rotate, and the movable seat 12 threadedly connected to the second screw 132 is fixed. Therefore, when the second screw 132 rotates, the mounting seat 11 will move relative to the movable seat 12, and when the mounting seat 11 and the rotating seat 111 move, the second support 151 will be pulled to move through the second screw 132 to maintain the distance between the rotating seat 111 and the second support 151.

[0039] Reference Figure 4 , Figure 6 and Figure 7 : The limiting component 32 includes a fixing ring 321 and a connecting ring 322; the fixing ring 321 is fixedly connected to the first support 31; the connecting ring 322 is fixedly connected to the threaded sleeve 311, and when the fixing ring 321 and the connecting ring 322 are in contact, the fixing ring 321 limits the rotation of the connecting ring 322; a control component 33 for controlling the movement of the connecting ring 322 is provided on the first bracket 21.

[0040] The present invention realizes the function of limiting the rotation of the threaded sleeve 311 through the fixing ring 321 and the connecting ring 322. And the connection between the linear drive assembly 22 and the first bracket 21 can be controlled by the control assembly 33. The connecting ring 322 is provided with a docking column 3221 and a first elastic member 313, and the connecting ring 322 is provided with a receiving groove for accommodating the docking column 3221. The docking column 3221 is slidably mounted on the connecting ring 322, and the two ends of the second elastic member 3222 are respectively connected to the docking column 3221 and the connecting ring 322, and the fixing ring 321 is provided with a docking groove 3211 that cooperates with the docking column 3221. In the working state, when the control component 33 controls the connection ring 322 to move toward the direction close to the fixed ring 321, when the docking column 3221 contacts the fixed ring 321, if the docking column 3221 is not aligned with the docking groove 3211, the docking column 3221 will be squeezed and contracted. When the connection ring 322 abuts against the fixed ring 321, the docking column 3221 contracts into the receiving groove. Then the first rotary driver 222 drives the first screw 221 to rotate. When the first screw 221 rotates, the threaded sleeve 311 is subjected to less resistance when rotating synchronously with the first screw 221. Therefore, the screw sleeve rotates synchronously with the first screw 221 first. The threaded sleeve 311 drives the connection ring 322 to rotate, and the connection ring 322 drives the docking column 3221 to rotate. When the docking column 3221 is aligned with the docking groove 3211, the docking column 3221 is plugged and matched with the docking groove 3211 under the elastic force of the first elastic member 313. Then, the connection ring 322 is restricted from rotating by the fixing ring 321, and the rotation of the threaded sleeve 311 is restricted. Then, the first screw 221 drives the threaded sleeve 311 to move, completing the transmission connection between the linear drive assembly 22 and the first bracket 21. When the control assembly 33 controls the connection ring 322 to separate from the fixing ring 321, the connection between the linear drive assembly 22 and the first bracket 21 is disconnected.

[0041] Reference Figure 6 and Figure 8 : The control component 33 includes a support ring 331, a guide rod 332 and a linear driver 333; the support ring 331 is rotatably connected to the connecting ring 322; the guide rod 332 is connected to the support ring 331, and the guide rod 332 is slidably matched with the first support 31; the linear driver 333 is arranged on the first bracket 21; a transmission component 34 is provided on the first bracket 21, and the linear driver 333 is transmission-connected to the guide rod 332 through the transmission component 34.

[0042] The present invention realizes the function of controlling the movement of the connecting ring 322 through the support ring 331, the guide rod 332, the linear driver 333 and the transmission assembly 34. The linear driver 333 is preferably a linear cylinder, and the linear driver 333 is electrically connected to the controller. When controlling the linear drive assembly 22 to be transmission-connected with the first bracket 21, the controller sends a signal to the linear driver 333. After receiving the signal, the linear driver 333 drives the guide rod 332 to move through the transmission assembly 34, and the guide rod 332 drives the support ring 331 to move, and the support ring 331 drives the connecting ring 322 and the threaded sleeve 311 to move until the connecting ring 322 abuts against the fixed ring 321, and the connecting ring 322 is restricted from rotating by the fixed ring 321 fixedly connected to the first support 31. Then the first bracket 21 is driven to move by the first rotation driver 222 and the first screw 221.

[0043] Reference Figure 6 , Figure 8 and Fig. 9 : The transmission assembly 34 includes a push block 341, a third elastic member 342 and a connecting strip 343; the push block 341 is slidably arranged on the first support 31, and a limit block 3411 is provided at the end of the push block 341 away from the first support 31; an inclined guide groove 3321 is provided on the guide rod 332, which is slidably matched with the push block 341; the two ends of the third elastic member 342 are respectively connected to the first support 31 and the limit block 3411; the connecting strip 343 is connected to the driving end of the linear driver 333.

[0044] The present invention realizes the function of simultaneously driving the guide rods 332 on the plurality of first brackets 21 to move through the linear driver 333 by means of the push block 341, the third elastic member 342 and the connecting strip 343. In the working state, when the linear driver 333 drives the connecting strip 343 to move downward, the connecting strip 343 drives the push block 341 on the first support 31 located below it, the third elastic member 342 contracts under the pressure, the push block 341 squeezes the oblique guide groove 3321 on the guide rod 332, and then drives the guide rod 332 to move, the guide rod 332 drives the support ring 331 to move in the direction close to the fixed ring 321, the support ring 331 drives the connecting ring 322 to move, so that the connecting ring 322 abuts against the fixed ring 321, and then the connecting ring 322 is restricted from rotating by the fixed ring 321.

[0045] Reference Figure 6 and Fig. 9 : A fixing plate 312 and a first elastic member 313 are provided on the first support 31; the fixing plate 312 is connected to the first support 31; one end of the first elastic member 313 is connected to the fixing plate 312, and the other end of the first elastic member 313 is abutted against the threaded sleeve 311 through a gasket.

[0046] The present invention realizes the function of controlling the threaded sleeve 311 to reset through the fixing plate 312 and the first elastic member 313. A through hole is provided on the fixing ring 321 for the first screw rod 221 to pass through. The two ends of the first elastic member 313 are respectively connected to the fixing plate 312 and the gasket, and the gasket is slidably matched with the threaded sleeve 311. The gasket is made of graphite, and the wear resistance and lubricity of the gasket reduce the obstruction to the rotation of the threaded sleeve 311. When the linear drive 333 controls the connection strip 343 to separate from the guide rod 332, the limit block 3411 on the push block 341 is reset by the elastic force of the third elastic member 342, thereby resetting the push block 341, and the push block 341 no longer applies an extrusion effect to the guide rod 332. At this time, the threaded sleeve 311 is reset under the elastic force of the first elastic member 313, thereby separating the connection ring 322 from the fixing ring 321.

[0048] The present invention realizes the function of driving the rotating seat 111 to rotate through the third rotating driver 141, the transmission shaft 142, the first rotating gear 143 and the second rotating gear 144. The third rotating driver 141 is preferably a servo motor, and the third rotating driver 141 is electrically connected to the controller. The driving end of the third rotating driver 141 and the transmission shaft 142 are both sleeved with a bevel gear 145, and the two bevel gears 145 are meshed and connected. When performing arc grooving, the control mounting seat 11 is connected to the adjusting mechanism 2 in transmission, and the connection between the movable seat 12 and the adjusting mechanism 2 is disconnected.

[0049] The controller sends a signal to the third rotation driver 141. After receiving the signal, the third rotation driver 141 drives the transmission shaft 142 to rotate through the bevel gear 145. The transmission shaft 142 drives the first rotating gear 143 to rotate. The first rotating gear 143 drives the second rotating gear 144 meshing with it to rotate. The second rotating gear 144 drives the rotating seat 111 to rotate. The rotating seat 111 drives the movable seat 12 to rotate through the second screw 132, and the arc groove is processed by the milling cutter 121 on the movable seat 12.
