Description

Technical Field

[0001] The utility model relates to the technical field of toothbrush production, in particular to a hot stamping device for toothbrush production. Background Art

[0002] Hot stamping, also known as thermography, is a printing and decoration process. By heating a metal printing plate and applying foil material, golden characters or patterns are embossed on printed products. With the rapid development of hot stamping foil and the packaging industry, the application of electrothermal aluminum hot stamping is becoming more and more widespread, including its application on toothbrush handles to enhance the appearance and value of products.

[0003] In Chinese Invention CN219769391U, a toothbrush handle hot stamping device is proposed. It clamps the toothbrush handle by the reverse rotation of the first clamping arm and the second clamping arm. After the first clamping arm and the second clamping arm cross, they push the toothbrush handle upward until the top of the toothbrush handle is squeezed against the bottom of the mounting seat, so as to fix the rectangular toothbrush handle. By setting a groove, when the toothbrush handle is round rod-shaped, the round rod-shaped toothbrush handle can be limited by the groove. Multiple rubber strips inside the groove can increase the friction with the toothbrush handle, further improving the stability of fixation.

[0004] Combined with the existing technology, in the process of implementing this application, the inventor found that there are at least the following problems in this technology: the hot stamping plate directly contacts the toothbrush handle, resulting in poor control of the hot stamping temperature, thus affecting the hot stamping effect and even damaging the toothbrush handle. Moreover, there is no structure for receiving and releasing the hot stamping paper to cooperate with the hot stamping plate during the hot stamping process of the toothbrush handle, further affecting the hot stamping effect.

[0023] In this embodiment, the hot stamping mechanism includes a bearing seat 4, which is fixedly installed at the output end of the linear motor 2. A regulating cylinder 5 is fixedly installed on the top of the bearing seat 4. The regulating cylinder 5 penetrates and extends below the bearing seat 4. The output end of the regulating cylinder 5 is fixedly installed with a protective shell 6. A heat-conducting roller 7 is rotatably installed inside the protective shell 6. A heating rod group 10 is fixedly installed inside the protective shell 6. A reduction motor 9 is fixedly installed on the back of the protective shell 6. The output end of the reduction motor 9 is fixedly connected to the back of the heat-conducting roller 7.

[0024] Specifically, when the toothbrush is transported by the conveyor 1 to below the heat-conducting roller 7, the regulating cylinder 5 is started to move the heat-conducting roller 7 downward, so that the hot stamping paper contacts the toothbrush handle. The heat-conducting roller 7 transfers the pattern on the hot stamping paper to the outside of the toothbrush handle. At the same time, the heat-conducting roller 7 is driven by the reduction motor 9 to rotate, so that the other side of the heat-conducting roller 7 is thermally baked by the heating rod group 10 during the hot stamping process. After the other side of the heat-conducting roller 7 rises to the required temperature, hot pressing is performed on the next toothbrush handle, realizing continuous and rapid hot pressing, avoiding direct contact between the heat source and the hot stamping paper and the toothbrush handle, and avoiding damage to the hot stamping paper and the toothbrush handle caused by rapid temperature rise.

A conduction assembly 15 is fixedly installed at the left end of the top of the bracket 11. A unwinding roller 16 is fixedly installed at the left end of the back of the conduction assembly 15. Two positioning plates are arranged outside the winding roller 13. The rear positioning plate is fixedly installed outside the winding roller 13. The front positioning plate is movably sleeved outside the winding roller 13. A fixing sleeve is fixedly installed outside the winding roller 13 through bolts.

The hand-tightening bolts penetrate the receiving frame and extend into the activity hole, and are rotatably connected to the ball bearing.

[0026] It should be noted that the setting of the compression spring, the fixing sleeve and the compression spring enables the hot stamping paper roll to be positioned after use. Cooperating with the conduction assembly 15, it avoids the deviation of the hot stamping paper during use and improves the hot stamping quality.

[0027] Specifically, put the unused hot stamping paper roll on the outside of the unwinding roller 16.
