Description

Technical Field

[0001] This utility model relates to the field of hot stamping, specifically a hot stamping device for processing cosmetic bottles. Background Technology

[0002] A cosmetic bottle hot stamping device is a specialized device used to decorate the surface of cosmetic containers with hot stamping. The hot stamping process involves heating and pressing metal foil onto the surface of an item to create exquisite patterns, text, or other design elements. It is often used to enhance the appearance and brand recognition of products.

[0003] When hot stamping the surface of cosmetic bottles of different shapes, in order to ensure that the hot stamping pattern is clear and evenly adhered, it is usually necessary to change the hot stamping mold that matches the bottle shape. During the changeover process, the mounting groove of the new hot stamping mold needs to be aligned with the mounting groove of the hydraulic device and then fixed with bolts. During the installation process, the staff often need to try to fine-tune the position multiple times to make the mounting groove fully aligned, which not only prolongs the mold changeover time but also reduces production efficiency. Utility Model Content

The splicing mechanism includes a positioning post, which is fixedly connected to the top of the hot stamping mold. The surface of the positioning post contacts the inner wall of the cylinder extension end. Two positioning rods are fixedly connected to the inner wall of the positioning post. Each of the two positioning rods has a locking block rotatably connected to its surface. One end of each locking block is fixedly connected to a positioning block, and the other end of each locking block is fixedly connected to a connecting block. A torsion spring is fitted onto the surface of each positioning rod. One end of the torsion spring is fixedly connected to the surface of the positioning rod, and the other end of the torsion spring is fixedly connected to the surface of the locking block. The inner wall of the cylinder extension end has four I-shaped grooves, which are used in conjunction with the locking blocks, positioning blocks, and connecting blocks.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a hot stamping apparatus for processing cosmetic bottles. (See also...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A hot stamping device for processing cosmetic bottles includes a workbench 1, a cylinder 3 is provided on the top of the workbench 1, a hot stamping mold 4 is provided at the bottom of the telescopic end of the cylinder 3, and a splicing mechanism 2 is provided on the top of the hot stamping mold 4. The splicing mechanism 2 includes a positioning post 201, which is fixedly connected to the top of the hot stamping mold 4. The surface of the positioning post 201 contacts the inner wall of the telescopic end of the cylinder 3. Two positioning rods 202 are fixedly connected to the inner wall of the positioning post 201. Each positioning rod 202 has a locking block 203 rotatably connected to its surface. One end of each locking block 203 is fixedly connected to a positioning block 205, and the other end is fixedly connected to a connecting block 206. A torsion spring 204 is fitted onto the surface of each positioning rod 202. One end of the torsion spring 204 is fixedly connected to the surface of the positioning rod 202, and the other end is fixedly connected to the surface of the locking block 203. An I-shaped groove 207 is formed on the inner wall of the telescopic end of the cylinder 3. There are four 7-shaped grooves 207, which work in conjunction with the locking block 203, the positioning block 205, and the connecting block 206. By setting up the splicing mechanism 2, the positioning block 205 on the top of the locking block 203 is inserted into the I-shaped groove 207 at the telescopic end of the cylinder 3, thus connecting the hot stamping mold 4 with the telescopic end of the cylinder 3. Then, by opening the connecting block 206, the locking block 203 can be rotated, which can release the locking between the positioning block 205 and the I-shaped groove 207, and release the locking between the telescopic end of the cylinder 3 and the hot stamping mold 4. This facilitates quick replacement of the hot stamping mold 4 without the need to use tools to disassemble and install multiple bolts. The locking and releasing of the hot stamping mold 4 can be completed simply by operating the connecting block 206, avoiding the problems of hot stamping pattern offset and false printing caused by installation deviation, and improving the replacement speed of the hot stamping mold 4.

[0018] Reference Figure 3 The inner wall of the positioning post 201 is provided with a pressing block 6. The surface of the pressing block 6 contacts the surface of the two connecting blocks 206. By setting the pressing block 6, the pressing block 6 can be pushed between the two connecting blocks 206, so that the two connecting blocks 206 are opened, and the locking block 203 is rotated, which can cancel the locking between the positioning block 205 and the I-shaped groove 207, thereby realizing the automatic disengagement between the positioning block 205 and the I-shaped groove 207. Reference Figure 3 The bottom of the extrusion block 6 is fixedly connected to a guide block 8, and the inner wall of the positioning post 201 is provided with a guide groove 9. The surface of the guide block 8 contacts the inner wall of the guide groove 9. The extrusion block 6 is slidably connected to the inner wall of the positioning post 201 through the guide block 8 and the guide groove 9. The guide block 8 and the guide groove 9 can guide and limit the extrusion block 6, ensuring that the extrusion block 6 moves along the preset path and preventing the extrusion block 6 from deviating when it moves. Reference Figure 3A tension spring 7 is provided between the extrusion block 6 and the inner wall of the positioning post 201. One end of the tension spring 7 is fixedly connected to the surface of the extrusion block 6, and the other end of the tension spring 7 is fixedly connected to the inner wall of the positioning post 201. The tension spring 7 can provide elastic potential energy to the extrusion block 6, ensuring that after the extrusion block 6 is pushed, it can automatically return to its original position without the need for manual removal of the extrusion block 6, thus reducing the number of operation steps. Reference Figure 3 One end of the extrusion block 6 is fixedly connected to a push rod 5. One end of the push rod 5 passes through the inner wall of the positioning post 201 and the telescopic end of the cylinder 3. The push rod 5 is designed to facilitate manual movement of the extrusion block 6 from the outside. There is no need to reach into the narrow area to push the extrusion block 6 directly. You only need to press the push rod 5 from the outside. Reference Figure 4 A rubber pad 10 is fixedly connected to the inner wall of the telescopic end of the cylinder 3. The bottom of the rubber pad 10 contacts the top of the positioning post 201. By setting the rubber pad 10, the position where the inner wall of the telescopic end of the cylinder 3 contacts the top of the positioning post 201 can be filled to prevent gaps from appearing at the connection and ensure the stability of the hot stamping mold 4 during use. Reference Figure 5 The hot stamping mold 4 has a limiting block 12 on its top. The inner wall of the limiting block 12 is in contact with the surface of the push rod 5. An arc-shaped block 13 is fixedly connected to the bottom of the limiting block 12. An arc-shaped groove 11 is opened on the top of the hot stamping mold 4. The surface of the arc-shaped block 13 is in contact with the inner wall of the arc-shaped groove 11. The limiting block 12 is slidably connected to the top of the hot stamping mold 4 through the arc-shaped block 13 and the arc-shaped groove 11. The setting of the limiting block 12 provides lateral support for the push rod 5, indirectly enhancing the stability of the hot stamping mold 4 installation.

[0019] Working Principle: The hot stamping machine uses a built-in heating system to heat the hot stamping mold 4 to a set temperature, sufficient to melt the adhesive layer on the hot stamping foil. The cosmetic bottle is placed on the hot stamping machine's worktable 1, and the automatic positioning device ensures that the area to be stamped on the bottle is aligned with the hot stamping mold 4. The hot stamping mold 4, under heating, contacts the bottle surface while applying appropriate pressure. Under the combined effects of temperature and pressure, the adhesive layer on the hot stamping foil melts, the aluminum layer separates from the base film, and is transferred to the bottle surface. When hot stamping irregularly shaped bottles, the mold needs to be changed. When the user presses the push rod 5, the push rod 5 moves the squeezing block 6 inward. At this time, the tension spring 7 is compressed. The compressed tension spring 7 stores elastic potential energy, which can be automatically released after the external force is removed, so that the push rod 5 and the squeezing block 6 automatically return to their initial positions. As the squeezing block 6 enters, the side of the squeezing block 6 forces the two connecting blocks 206 to open outward. The opening of the connecting blocks 206 causes the connecting locking block 203 to rotate around the positioning rod 202, thereby causing the torsion spring 204 to twist. After the external force is removed, the torsional elasticity of the torsion spring 204 can keep the locking block 203 automatically resets. After the locking block 203 rotates, the top positioning block 205 disengages from the I-shaped groove 207, releasing the mechanical lock. At this point, the entire hot stamping mold 4 can be removed, completing quick disassembly. When installing the hot stamping mold 4, the user inserts the positioning pin 201 into the telescopic end of the cylinder 3. During the pushing process, the positioning block 205 enters the inlet of the I-shaped groove 207. When the top of the positioning block 205 contacts the inner wall of the telescopic end of the cylinder 3, the positioning block 205 will experience resistance, generating a downward force. This force is transmitted to the locking block 203, causing the locking block to... 203 rotates around the positioning post 201, and the torsion spring 204 is twisted to store torsional potential energy. At the same time, it drives the positioning block 205 to deflect downward, temporarily disengaging from the resistance area and forming a yielding state. Under the continuous thrust, the positioning block 205 crosses the step obstacle at the entrance of the I-shaped groove 207 and smoothly slides into the interior of the telescopic end of the cylinder 3. When the positioning block 205 is fully inside the transverse channel of the I-shaped groove 207, the external resistance disappears, the torsion spring 204 releases the stored torsional potential energy, drives the locking block 203 to rotate in the opposite direction, and drives the positioning block 205 back to the center, forming a lock.
