Technical Field

[0001] This utility model relates to the field of toothbrush handle surface embossing technology, and in particular to a toothbrush handle surface texture embossing device. Background Technology

[0002] Most toothbrushes on the market consist of three parts: the handle, the brush head, and the bristles. The handle serves as the main support structure, used for gripping and transmitting the force of brushing. To improve the anti-slip performance of the toothbrush handle and to some extent enhance the overall aesthetics of the toothbrush, textures are pressed into the handle using an embossing process to reduce slippage during use.

[0003] Currently, the most common embossing method is hot pressing, which uses a heated mold to directly press the design onto the toothbrush handle to form the desired embossed shape. However, the hot pressing molds on common embossing devices are mostly fixed and difficult to replace. Since different customers need different types of toothbrushes, it takes time to replace the entire hot pressing mold assembly when embossing different toothbrush handles, thus reducing embossing efficiency.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1-7The toothbrush handle surface texture embossing device includes: a recessed support base 1, with a rodless cylinder 2 fixed inside the recess of the support base 1; an intermediate connecting frame 3 fixed on its slider; rectangular frame sleeves 4 fixed on both sides of the intermediate connecting frame 3 for holding the toothbrush handle to be embossed; a back support plate 5 fixed inside the recess of the support base 1, with a drive shaft 6 rotatably mounted on it; a cross connecting piece 7 fixed at one end of the drive shaft 6; and a drive motor fixed on one side of the back support plate 5, its output shaft connected to the drive shaft 6. One end is fixedly connected to a cross-shaped connecting piece 7, on which four horizontally protruding support plates 8 are fixedly arranged in a ring array. Each of the four horizontally protruding support plates 8 is fixed with an electric push rod 9. The output shafts of the four electric push rods 9 pass through the corresponding horizontally protruding support plates 8 and are slidably connected to the corresponding horizontally protruding support plates 8. Each of the four electric push rods 9 is fixed with a pressure mold assembly, which is used to emboss the toothbrush handle. The four pressure mold assemblies have different specifications and sizes. The corresponding pressure mold assembly can be quickly selected for embossing by rotating the cross-shaped connecting piece 7, thereby improving the embossing efficiency.

[0025] In the above-mentioned method, any of the proposed molding components includes a hot pressing mold 10, which has an installation port and an electric heating element 11 is fixed inside the installation port.

[0026] In this method, since the length of the toothbrush handle varies depending on customer needs, to ensure the embossing position meets design requirements, adjusting screws 12 are rotatably installed inside both rectangular frames 4. Sliding blocks 13 are threaded onto both adjusting screws 12, and round connecting rods are fixed to the top of each sliding block 13. The tops of both round connecting rods penetrate the tops of the corresponding rectangular frames 4 and slide together with them. End baffles 14 are fixed to the tops of both round connecting rods. By rotating the adjusting screws 12, the position of the end baffles 14 can be changed, allowing for embossing according to different toothbrush handle lengths. Furthermore, two telescopic cylinders 15 are fixed to the tops of both rectangular frames 4, and four... Mounting plates 16 are fixed on the output shaft of each of the four mounting plates 15. Two clamping strips 17 are fixed to the bottom of each of the four mounting plates 16. The bottom of the clamping strips 17 contacts the top of the rectangular frame 4. The height of the clamping strips 17 is lower than the thickness of the toothbrush handle, and the distance between the two clamping strips 17 is relatively long so as not to hinder the normal embossing work. In order to facilitate the rotation of the adjusting screws 12, a rotating handle is fixed to the outside of the corresponding rectangular frame 4 at the ends of the two adjusting screws 12 that are far apart from each other. A connecting ear is fixed on the side of the two rectangular frame 4 that is far apart from each other. A set screw is threaded on the two connecting ears. The ends of the two set screws abut against the two adjusting screws 12 respectively. The set screw can prevent the adjusting screws 12 from rotating naturally.

[0027] In this method, in order to cool down the toothbrush handle which is hot after embossing, a through groove 18 is provided on the recessed support 1, and a fan 19 is fixed inside it. The same air duct 20 is fixed on the inner walls of both sides of the through groove 18. The air outlet of the fan 19 is fixedly connected to the air duct 20. One end of two air guide bends 21 is fixed on the air duct 20. The other end of the two air guide bends 21 extends to the top of the rectangular frame 4 and is fixed with a spray hood 22. Each of the two air guide bends 21 is equipped with an air valve. Whenever the embossed toothbrush handle moves to the bottom of the corresponding spray hood 22, the corresponding air valve is opened and the fan 19 is run to use strong air to blow and cool down the toothbrush handle, thereby further accelerating the embossing efficiency.

[0028] In this method, in order to ensure that the sliding block 13 can only perform linear movement, guide slides are provided at the top of the two rectangular frames 4, and the two round connecting rods pass through the two guide slides respectively and contact the inner wall of the corresponding guide slides.

[0029] The working principle of the toothbrush handle surface texture embossing device provided by this utility model is as follows:

[0030] In this device, the hot pressing molds 10 in the four pressing mold assemblies are all different, and the four hot pressing molds 10 are all commonly used embossing molds.

[0031] When it is necessary to emboss the upper surface of the toothbrush handle, first adjust the position of the end baffle 14 according to the length of the toothbrush handle to be embossed. During adjustment, reverse the two set screws to separate the two set screws from the corresponding adjusting screws 12. Then rotate the two adjusting screws 12 so that the end baffle 14 can be moved horizontally. After adjusting it to the specified position, tighten the two set screws again. Then place the two toothbrush handles on the two rectangular frame sleeves 4 and make the ends of the two toothbrush handles away from the brushes contact the two end baffles 14 respectively. Then activate the output shafts of the four telescopic cylinders 15 to extend, and the corresponding two mounting plates 16 move towards each other. Finally, clamp the toothbrush handle from the side using the clamping bar 17.

[0032] Then, select the specified hot press mold 10 according to the requirements. When selecting, start the drive motor in the forward direction. Its output shaft drives the transmission shaft 6 to rotate, which in turn can rotate the cross connecting piece 7. Whenever the cross connecting piece 7 rotates 90°, the drive motor stops for a moment until the required hot press mold 10 is rotated to the bottom and the drive motor is locked. Then, start the output shaft of the corresponding electric push rod 9 to extend. Its output shaft will bring the corresponding hot press mold 10 down. When it contacts the toothbrush handle, the embossing process begins.

[0033] After the embossing is completed, the output shaft of the electric push rod 9 is retracted, bringing the hot press mold 10 back to its original position. Then, the rodless cylinder 2 is activated, and the slider on it moves horizontally with the intermediate connecting frame 3 until the slider on the rodless cylinder 2 moves from one side to the other side. The rectangular frame 4 that was originally under the hot press mold 10 is completely removed, and another rectangular frame 4 moves to the bottom of the hot press mold 10. Then, the next embossing work continues.

[0034] While the embossing process is underway, the corresponding air valve is opened and the blower 19 is started. The blower 19 delivers a powerful airflow into the corresponding air guide duct 21, which is then sprayed out through the air spray hood 22. This allows for rapid cooling of the toothbrush handle that has just been embossed. After cooling, the toothbrush handle is removed, and the next toothbrush handle to be embossed is fixed in place. This process continues until the previous embossing process is completed. Then, the rodless cylinder 2 is started again to change the position of the two rectangular frames 4. Based on the same principle, the embossing process continues while the cooling and shaping process is being carried out. This process is repeated.

[0035] Compared with related technologies, the toothbrush handle surface texture embossing device provided by this utility model has the following beneficial effects:

[0036] This utility model provides a toothbrush handle surface texture embossing device. With the setting of a rotatable cross connecting piece 7, and four pressing mold components set on the cross connecting piece 7, the corresponding hot pressing mold 10 can be quickly selected for use according to actual needs, without the need for time-consuming and laborious disassembly and replacement of the entire pressing mold assembly, thus improving embossing efficiency. Furthermore, at the end of embossing, the embossed toothbrush handle can be quickly cooled and shaped by the operation of the fan 19, thereby ensuring that the embossed shape can be as perfect as possible and improving the embossing effect.
