[0002] In the modern daily necessities manufacturing industry, toothbrushes are daily necessities, and their production efficiency and product quality are crucial. Toothbrush handles are usually molded using the injection molding process, which has the advantages of high production efficiency, low cost and large-scale production. However, the edges of the toothbrush handles after injection molding often have burrs and unevenness. These defects not only affect the aesthetics of the product, but may also cause harm to users during use, reducing user experience. Therefore, edge trimming of injection molded toothbrush handles is an indispensable part of the production process.

[0003] When trimming existing injection-molded toothbrushes, they usually rely on manual loading and unloading or demoulding operations.

[0029] Next, please refer to Figures 7 to 12 The storage assembly 21 includes a processing table 211 fixedly connected to the left side of the bracket 111, a drainage cover 212 is fixedly installed in the middle of the inner cavity of the processing table 211, and a box door 213 is hinged at the bottom of the front of the processing table 211; The clamping assembly 22 includes a rotating frame 221 rotatably connected to the middle part of the inner cavity of the processing table 211, a motor 222 is fixedly installed on the rear side of the processing table 211, the output shaft of the motor 222 is fixedly connected to the rear side of the rotating frame 221, a clamping rod 223 is slidably connected to the inner cavity of the rotating frame 221, a motor 224 is fixedly installed on the inner cavity of the clamping rod 223, a rotating shaft 225 is fixedly connected to the output shaft of the motor 224, the outer end of the rotating shaft 225 extends out of the clamping rod 223 and is fixedly connected to a clamping pad 226, a positioning groove 227 is provided in the inner cavity of the clamping rod 223, a positioning ball 228 is slidably connected to the inner cavity of the rotating shaft 225, the positioning ball 228 is movably sleeved in the positioning groove 227, and a spring 229 is fixedly connected to the bottom of the inner cavity of the rotating shaft 225. The fixing assembly 33 includes a flip rod 331 rotatably connected to the left side of the inner cavity of the processing table 211, a motor 5 332 is fixedly installed in the left inner cavity of the processing table 211, the output shaft of the motor 5 332 is fixedly connected to the axis of the flip rod 331, and a mechanical claw 2 333 is fixedly installed on the bottom surface of the flip rod 331; Electric drive rails are installed on both the left and right sides of the rotating frame 221, and the clamping rod 223 is slidably connected in the electric drive rails.

[0030] It should be noted that the contact portion between the processing table 211 and the rotating frame 221 is provided with a contact-type ring-shaped power supply device, and the power supply device is connected to the mains to supply energy to the electrical components in the rotating frame 221; The clamping pad 226 is a concave non-slip material pad, which is intended to improve the stability of clamping; The clamping jaws of the mechanical claw 2 333 are provided with retractable anti-slip strips, so that when clamping the toothbrush, the anti-slip strips can be squeezed and retracted into the inside of the clamping jaws, thereby increasing the clamping strength and improving the clamping stability; The length of the flip rod 331 is smaller than the height of the fixing frame 311, so that the flip rod 331 can be rotated upward when not needed, so as to avoid affecting the trimming operation of the toothbrush.

[0031] In this embodiment, during trimming, the mechanical claw 136 transports the toothbrush to the middle of the front and rear clamping pads 226, and then the front and rear clamping rods 223 approach each other to clamp and fix the two ends of the toothbrush, and perform the grinding and trimming operation. The residues generated during the trimming are recovered to the bottom of the inner cavity of the processing table 211 through the drainage cover 212. After the processing is completed, the box door 213 is opened to collect it. At the same time, the motor 224 will drive the rotating shaft 225 and the clamping pad 226 to rotate, and then drive the toothbrush to flip and adjust the direction, so as to perform fine grinding. During the rotation process, the positioning ball 228 will be separated from the positioning groove 227.

[0033] It should be noted that the grinding disc 328 located at the right station is a disc-shaped grinding wheel, while the grinding disc 328 located at the left station is a conical grinding wheel, which is designed to allow the toothbrush to be roughly ground at the right station and then transferred to the left station for detailed grinding, thereby improving the comfort and completeness of the trimming and improving the efficiency of grinding.

[0034] In this embodiment, during the grinding process, the electric guide rail four 312 and the electric guide rail five 313 operate to adjust the position of the sliding frame 314, and then the electric push rod three 323 pushes the grinding disc 328 down to approach the toothbrush, and then the electric push rod four 326 operates to push the mounting box 325 to rotate and adjust the inclination angle of the grinding disc 328, and the motor three 321 drives the rotating plate 322 to rotate and adjust the rotation direction of the grinding disc 328, thereby realizing all-round control of the grinding disc 328 and improving the comprehensiveness and efficiency of toothbrush grinding.

[0035] The working principle of the present invention is as follows: before trimming, the conveyor belt 112 transports the injection block 121 to the crawler 113, at which time the electric push rod 133 pushes the limit plate 134 close to the injection block 121, and the injection molded toothbrush is cut off by the cutting knife 135, and then the slider 125 slides in the electric guide rail 124, so that the push rod 127 is aligned with the continuous groove 123 of the injection block 121, and the electric push rod 126 extends to push the push rod 127 to eject the toothbrush from the injection block 121, and then the mechanical claw 136 clamps and fixes the toothbrush, and through the operation of the electric guide rail 2 131 and the electric guide rail 3 132, the toothbrush is transported to the middle of the front and rear clamping pads 226. Then the front and rear clamping rods 223 approach each other to clamp and fix the two ends of the toothbrush, and the trimming operation is performed. At the same time, the motor 224 drives the rotating shaft 225 and the clamping pad 226 to rotate, and then drives the toothbrush to flip and adjust the direction, so as to perform all-round grinding. During the grinding process, the electric guide rail 4 312 and the electric guide rail 5 313 ​​operate to adjust the position of the sliding frame 314, and then the electric push rod 3 323 pushes the grinding disc 328 to descend close to the toothbrush, and then the electric push rod 4 326 operates to push the installation box 325 to rotate and adjust the inclination angle of the grinding disc 328, and the motor 3 321 drives the rotating plate 322 to rotate and adjust the rotation direction of the grinding disc 328, thereby realizing all-round control of the grinding disc 328. After the toothbrush is polished and corrected, the motor 1 222 drives the rotating frame 221 to flip, so that the toothbrush is flipped to another station, and the other station can receive a new injection molded toothbrush for grinding and trimming. The toothbrush in the new station will be polished more finely, and the motor 5 332 will drive the flip rod 331 to descend, and use the mechanical claw 2 333 to clamp the middle of the toothbrush, and then release the two ends of the toothbrush to polish and trim the two ends of the toothbrush. After the toothbrush is trimmed, it will be transferred to the station on the right, and then the mechanical claw 1 136 will take back the trimmed toothbrush and place it on the top of the injection block 121. After the toothbrushes in the injection block 121 are trimmed, they can be transported to the subsequent process through the crawler 113 and the conveyor belt 112.

[0036] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the art unless otherwise specified and limited.
