Combined with the limiting effect of the positioning groove itself, the position of the bathtub can be kept stable during the edge-cutting process, preventing the bathtub from shifting due to vibrations or external pushing during edge-cutting, thus ensuring the edge-cutting effect. By setting up a lifting device, lifting platform, and electric slide rail, the lifting device and lifting platform can drive the edge-cutting blade wheel to move up and down, which facilitates the subsequent placement and removal of the bathtub to be processed, making it convenient to use. At the same time, the electric slide rail can drive the edge-cutting blade wheel to move cyclically. By simply adjusting the shape of the electric slide rail, the movement path of the edge-cutting blade wheel can be controlled, thereby realizing the automated edge-cutting work of the edge-cutting blade wheel, which greatly improves work efficiency compared to the previous manual edge-cutting operation.

[0009] Furthermore, this invention also features a protective cover over the outer side of the cutting blade. This cover effectively blocks dust generated during the cutting process, preventing dust from flying everywhere and causing discomfort in the working environment. This improves work comfort and facilitates cleaning, while also preventing injury to operators from flying dust and avoiding accidents caused by direct contact between operators and the cutting blade, thus enhancing safety. Additionally, a pressure sensor is installed on the bottom surface of the protective cover to detect whether the bottom surface of the cover is in contact with the top surface of the edge to be cut on the bathtub, thereby automatically controlling the start time of the cutting motor. This design facilitates use; by framing the protective cover as a frustum (smaller at the top and larger at the bottom), it provides ample operating space for the cutting blade, ensuring operational stability; the cushioning pad on the top surface of the ejector seat absorbs vibrations from the bathtub caused by external forces during the cutting process, and the multiple cushioning elements further limit the bathtub's position, ensuring operational stability; the annular support at the opening of the receiving groove provides support for the ejector seat, reducing the pressure of the bathtub on the ejector cylinder during cutting, thus mitigating damage to the ejector cylinder and extending its service life. Therefore, this invention not only improves work efficiency but also offers advantages such as good cutting effect, ease of use, high safety, high comfort, high operational stability, and long service life.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] Example. An automatic edge-cutting device for bathtub production, configured as follows: Figures 1 to 5 As shown, the bathtub includes a trimming base 1, a trimming motor 2, and a trimming cutter wheel 3 connected to the trimming motor 2. The top surface of the trimming base 1 is provided with a positioning groove 4 for placing the bathtub, and the inner bottom surface of the positioning groove 4 is provided with a push-out device. Each inner side wall of the positioning groove 4 is provided with multiple clamping cylinders 5 for fixing the bathtub. Each clamping cylinder 5 is connected to a clamping element 6, and each clamping element 6 is covered with a first buffer pad 7. A gantry frame 8 is provided directly above the positioning groove 4, and a lifting device is provided on the gantry frame 8. A lifting platform 9 is connected to the lifting device, and an electric slide rail 10 with closed ends is provided on the bottom surface of the lifting platform 9. A trimming moving seat 11 is slidably connected to the electric slide rail 10. The trimming motor 2 and the trimming cutter wheel 3 are both located on the bottom surface of the trimming moving seat 11.

[0018] The lifting device includes two ball screws 14 respectively installed on the inner sidewall of the gantry frame 8. Each ball screw 14 is connected to a servo motor 15 at its end, and a nut seat is slidably installed on each ball screw 14. The lifting platform 9 is fixedly installed on the nut seat. The pushing device includes two symmetrically distributed pushing cylinders 16. A pushing seat 17 is installed between the top ends of all pushing cylinders 16. A second buffer pad 19 is laid on the top surface of the pushing seat 17. A receiving groove is provided on the bottom surface of the positioning groove 4 at the position corresponding to the pushing cylinder 16. A support member 20 for supporting the pushing seat 17 is provided at the top end of the inner sidewall of the receiving groove.

[0019] Working principle: When performing the trimming operation, first connect the entire device to an external safe mains power supply to power and activate the pressure sensor 13 (the pressure sensor 13 used in this invention can be a PX309-200A5V, PXM600MU-350BARGV, or PXM600MU-70BARGV model, etc.); then, control the ejection cylinder 16 to start, which will push the ejection seat 17 upward until its top surface is level with the top surface of the trimming base 1; then, place the bathtub to be trimmed on the ejection seat 17. After the bathtub is in place, control the ejection cylinder 16 to stop. This will cause the ejector seat 17 to move into the positioning groove 4. During the movement of the ejector seat 17, the bathtub will move simultaneously, allowing the bathtub to enter the positioning groove 4. Until the bottom surface of the ejector seat 17 contacts the inner bottom surface of the positioning groove 4, the support member 20 at the opening of the receiving groove can also reduce the pressure of the ejector seat 17 on the ejector cylinder 16, thereby reducing damage to the ejector cylinder 16 and extending its service life. After the ejector seat 17 has moved the entire bathtub into the positioning groove 4 and stopped moving (at this time, the edge of the bathtub that needs to be trimmed is attached to the top surface of the trimming base 1 and located outside the positioning groove 4), the clamping cylinder 5 is activated. After the clamping cylinder 5 is activated, it will cause the clamping member 6 to move in the opposite direction towards the bathtub. This allows all clamping components 6 to fix the position of the bathtub's side, ensuring that the bathtub will not shift during the subsequent edge trimming process. After the clamping components 6 are in place, the servo motor 15 is started. The servo motor 15 drives the ball screw 14 to rotate, which in turn moves the nut seat towards the edge trimming base 1. During the movement of the nut seat, the lifting platform 9 moves together, which in turn moves the edge trimming motor 2 and the edge trimming cutter wheel 3. As the lifting platform 9 continues to move, the telescopic sleeve at the bottom of the protective cover 12 will first contact the top surface of the bathtub's side. At this time, the pressure sensor 13 will generate a sensing signal and send it to the external controller (this controller is located on the edge trimming base 1). On the side, a programmable controller such as FX2C-20MRD, Cortex-R8, or Cortex-M7 can be used. After receiving the signal from the pressure sensor 13, the controller will start the cutting motor 2 and stop the servo motor 15 after 2 seconds. The electric slide rail 10 will start after 2 seconds. After the cutting motor 2 starts, it will drive the cutting blade wheel 3 to rotate at high speed. With the ball screw 14, it will continue to drive the lifting platform 9 to move downward. The cutting blade wheel 3 will cut the bathtub in the opposite position. When the servo motor 15 stops after 2 seconds, the cutting blade wheel 3 will have just cut the edge of the bathtub. At this time, the lifting platform 9 will stop moving, and the cutting blade wheel 3 will no longer move downward.Simultaneously, the electric slide rail 10 is activated, which drives the trimming moving seat 11 to move cyclically along the electric slide rail 10. When the trimming moving seat 11 moves, it drives the trimming motor 2 and the trimming cutter wheel 3 to move together, so that the highly rotating trimming cutter wheel 3 can automatically trim the bathtub. After the trimming moving seat 11 drives the trimming cutter wheel 3 to move one revolution along the electric slide rail 10, the electric slide rail 10 and the trimming motor 2 are stopped, so that the trimming cutter wheel 3 stops rotating and moving. Then, the servo motor 15 is started in reverse. After the servo motor 15 starts in reverse, it drives the lifting platform 9 to move upward. During the upward movement of the lifting platform 9, the trimming process is carried out. The cutting wheel 3 moves upward together, separating the cutting wheel 3 and the protective cover 12 from the top side of the bathtub. After the lifting platform 9 returns to its initial position, the clamping cylinder 5 is stopped. After the clamping cylinder 5 stops, it will drive the clamping part 6 to move towards the inner wall of the positioning groove 4, thus separating the clamping part 6 from the side wall of the bathtub. Finally, the ejection cylinder 16 is started. After the ejection cylinder 16 starts, it will drive the ejection seat 17 to move upward. As the ejection seat 17 moves, the bathtub that has completed the cutting work on the ejection seat 17 will also be ejected from the positioning groove 4. After the entire bathtub is completely ejected from the positioning groove, the bathtub that has completed the cutting work can be taken out, and then a new bathtub can be placed on it for the next cutting work.
