Description

Technical Field

[0001] This utility model relates to the field of toothbrush processing technology, specifically to a bristle end-face trimming device for an oblique bristle toothbrush. Background Technology

[0002] In the manufacturing process of angled bristle toothbrushes, the trimming of the bristle ends is a crucial step in ensuring product quality, improving user comfort, and enhancing aesthetics. This trimming typically relies on operators holding the toothbrush and pressing the bristle ends against a high-speed rotating grinding disc. However, manual operation is highly susceptible to subjective factors such as the operator's hand stability, force applied, and visual judgment accuracy. It's also difficult to control the contact depth between the bristles and the grinding disc, easily leading to uneven bristle ends. This directly results in significant differences in the trimming effect even within the same batch and model of toothbrushes. Some toothbrushes have bristles that are too short, affecting cleaning function, while others retain excessively long stray bristles due to insufficient trimming, severely compromising product consistency. Utility Model Content

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] like Figure 1-3As shown, a bristle end-face trimming device for an oblique-bristle toothbrush includes a worktable 1, a motor 2, a grinding disc 3, and a loading mechanism. The motor 2 is mounted on the lower end of the worktable 1, and the grinding disc 3 is rotatably connected to the upper end of the worktable 1. The output end of the motor 2 passes upward through the worktable 1 and is connected to the grinding disc 3 for transmission. A guide rail is provided on the worktable 1, and the lower end of the loading mechanism is slidably connected to the guide rail. A groove 502 is provided on the upper end of the loading mechanism. The outline and size of the groove 502 correspond to the toothbrush handle. The groove 502 can move with the loading mechanism and face the grinding disc 3. One end of the toothbrush loaded in the groove 502 enters the upper end of the grinding disc 3, with the toothbrush bristles facing downward and aligned with the upper end of the grinding disc 3. The device achieves surface contact for trimming the toothbrush bristles. During the process of the toothbrush bristles entering the upper surface of the grinding disc 3, the bristles move laterally into the area of ​​the grinding disc 3. However, the bristles of a slanted toothbrush are slanted in the front-to-back direction. Therefore, during the contact with the grinding disc 3, the lower end of the bristles is slightly offset by the force exerted by the grinding disc 3 to the left or right, while the contact depth between the bristles and the grinding disc 3 remains essentially constant. If the toothbrush enters the area of ​​the grinding disc 3 tangentially, the bristles will oscillate randomly under the force of the grinding disc 3, resulting in inconsistent contact depths and ultimately uneven bristle trimming. This device enables rapid loading and positioning of toothbrushes, ensuring the trimming effect of toothbrushes of the same model. It also ensures that the contact depth and trimming effect of the bristles on the grinding disc 3 remain essentially constant during trimming of slanted toothbrushes, improving product consistency and aesthetics, and avoiding the uneven bristle end faces caused by instability when manually holding and trimming toothbrushes.

[0018] The loading mechanism includes a slider 4 and a mold 5. The slider 4 is slidably connected to a guide rail, and the mold 5 is mounted on the upper end of the slider 4. The groove 502 is located on the mold 5. The slider 4 is made of metal to ensure smooth sliding connection with the guide rail. The mold 5 is made by 3D printing. Different grooves 502 are formed according to the modeling data of the handles of different toothbrush models, and multiple molds 5 are printed, which is convenient, quick, and saves a lot of mold-making costs. The upper end of the slider 4 is provided with a guide post 401, and the mold 5 is provided with a guide hole 501. The guide post 401 is slidably connected to the guide hole 501. The guide post 401 provides positioning and assembly for the mold 5, ensuring that the mold 5 will not move laterally, and providing stable working conditions for toothbrush bristle trimming. The upper end of the slider 4 is provided with a lifting groove 402, and a lifting platform 6 is slidably connected in the lifting groove 402. The front end of the slider 4 is provided with a first threaded hole 403 that communicates with the lifting groove 402. A first long screw 7 is threadedly connected in the first threaded hole 403. The front end of the lifting platform 6 is an inclined surface, and the first long screw 7 can abut against the inclined surface. The lifting platform 6 can abut against the mold 5 upwards. The front end of the first long screw 7 has a beveled angle, which can fit with the inclined surface of the lifting platform 6. By rotating the first long screw 7, the horizontal thrust is converted into a vertical thrust by means of the inclined surface, thereby lifting the lifting platform 6 and raising the mold 5 mounted on the upper end of the lifting platform 6. This can accommodate toothbrushes of different sizes and adjust the contact depth between the toothbrush bristles and the grinding disc 3, ensuring that different toothbrush models can obtain a good bristle end face trimming effect. The slider 4 has a second threaded hole 404 on its side that connects to the lifting groove 402. A second long screw 8 is threaded into the second threaded hole 404 and abuts against the side of the lifting platform 6. The second long screw 8 is perpendicular to the side of the lifting platform 6 and can lock the lifting platform 6 to prevent displacement of the lifting platform 6 under force during the use of the mold 5, thus providing a stable height for the mold 5 and the toothbrush loaded therein. Two grinding discs 3 and two motors 2 are each provided. The two grinding discs 3 rotate in opposite directions, allowing the toothbrush bristles to be trimmed in two directions on the two grinding discs 3 during a single loading, improving trimming efficiency.

[0019] The angled bristle toothbrush is placed upside down on the groove 502 of the mold 5 of this device. By pressing the toothbrush into the groove 502 by hand, the slider 4 is pushed to move laterally on the guide rail, moving the toothbrush bristles laterally to the area where the grinding disc 3 is located, preferably until the toothbrush is directly facing the center of the grinding disc 3. The bristles of the angled bristle toothbrush come into contact with the grinding disc 3 and are trimmed. During the trimming process, the contact depth between the bristles and the grinding disc 3 remains basically unchanged. After trimming by the two grinding discs 3 on the left and right, the bristles of the angled bristle toothbrush solve the problems of sharp bristle tips and edge burrs, optimize the bristle shape, reduce brushing resistance, and extend the bristle life.
