[0002] Collectibles come in a wide variety of categories, covering multiple fields such as art, history, and culture. Precious metals are one of the categories of collectibles. When precious metals are processed, the text to be printed is pressed onto the gold sheet to form the finished product, such as the logos and information printed on the front and back of the existing gold bars.

[0003] The prior art discloses a deep processing device for precious metals with application number CN202420209808.X. This device can automatically wash, clean and dry the used precious metal bottom molds in sequence. It uses the rotating method to clean the used precious metal bottom molds one by one in combination with the cleaning and re-use of them. This facilitates automatic and synchronous cleaning and printing work, without the need to consume separate washing, cleaning and drying time, saving time and labor, and improving the degree of automation and work efficiency.

[0004] However, this device relies on the rotation of a motor to drive the circular base, which increases the cost and energy consumption of the device. Furthermore, the embossing mold of this device is not easy to replace as needed and cannot change the embossing content, which has significant limitations. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a collectible stamping device to solve the technical problems in the background art mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a collectible stamping device, comprising a worktable, a fixed frame at the top of the worktable, a hydraulic rod mounted on the top of the fixed frame, an installation plate fixed to the output end of the hydraulic rod, a fixed plate at the bottom of the installation plate, a connecting shaft mounted on the inner side of the fixed plate, an upper stamping mold fixed to the outer surface of the connecting shaft via a fixed rod, a worm gear fixed to one end of the connecting shaft, a worm gear mounted on the back of the fixed plate, a toothed rod fixed to the back of the installation plate, a rotating shaft and a guide plate respectively mounted inside the worktable, a rotating frame and a pawl respectively mounted on the outer surface of the rotating shaft, and a spring mounted on the inner side of the pawl, a piston chamber inside the rotating frame, a piston plate inside the piston chamber, a piston rod fixed to the piston plate, a lower stamping mold fixed to one end of the piston rod via a magnetic block, and a rotating cylinder mounted on the back of the worktable via an installation ring, a toothed ring on the outer surface of the rotating cylinder, and ratchet teeth fixed to the inner wall of the rotating cylinder.

[0007] Furthermore, a hot air blower is installed above one side of the workbench, and a hot air nozzle is connected to the air outlet of the hot air blower.

[0008] By adopting the above technical solution, the hot air generated by the hot air blower is sprayed out through the hot air nozzle, which can then dry the lower mold.

[0009] Furthermore, a water pump is installed inside the lower part of the workbench, and the water outlet of the water pump is connected to multiple flushing heads through a water supply pipe.

[0010] By adopting the above technical solution, a water pump can draw up cleaning water, which is then sprayed out through a water pipe and a rinsing head to rinse the lower mold.

[0011] Furthermore, the workbench is provided with a chip discharge port and a material discharge port on both sides.

[0012] By adopting the above technical solution, the chip discharge port facilitates the discharge of chips, while the material discharge port facilitates the discharge of precious metals.

[0013] Furthermore, the top side of the guide plate has several filter holes.

[0014] By adopting the above technical solution, the filter holes facilitate the filtration of cleaning water, thereby facilitating the recycling of the cleaning water.

[0015] Furthermore, a control panel is installed on the outer surface of the workbench, and the hot air blower, water pump, and hydraulic rod are all electrically connected to the control panel.

[0016] By adopting the above technical solution, staff can easily control the hot air blower, water pump, and hydraulic rod through the control panel.

[0017] Furthermore, slide bars are fixed on both sides of the top of the workbench, and the mounting plate slides in conjunction with the slide bars.

[0018] By adopting the above technical solution, the vertical displacement of the mounting plate is made more stable under the action of the sliding rod.

[0019] Furthermore, the bottom of the workbench is fixed with support legs, and the bottom of the support legs is provided with shock-absorbing pads.

[0020] By adopting the above technical solution, the support legs can support the workbench, while the shock-absorbing pads can make the workbench more stable and play a certain role in shock absorption.

[0021] Furthermore, the upper printing mold is provided in four sets, and the four sets of upper printing molds are distributed in a ring shape on the outer surface of the connecting shaft.

[0022] By adopting the above technical solution, the rotation of the connecting shaft enables the four sets of upper printing molds to rotate, and the rotation of the four sets of upper printing molds facilitates replacement according to the printing requirements.

[0023] Furthermore, a knob is fixed to the bottom end of the worm gear.

[0024] By adopting the above technical solution, workers can easily rotate the worm gear using a knob, making the rotation of the worm gear more convenient.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model, by comprising a rack, ratchet, pawl, rotating drum, and toothed ring, allows the rack to mesh with the toothed ring when the hydraulic rod pushes the mounting plate downward, thereby driving the rotating drum to rotate. At this time, the ratchet and pawl are in a non-stressed state, so the rotating drum idles. After the imprinting is completed, the rack moves upward, which drives the toothed ring and rotating drum to reverse. At this time, the ratchet and pawl are in a stressed state, and the rotation of the rotating drum drives the rotating shaft to rotate, thereby causing the rotating frame to rotate 90°. This allows the imprinted precious metal to fall onto the guide plate, while the imprinting groove on the other rotating frame faces upward, making it easier to place the next precious metal. This method eliminates the need for an additional motor-driven rotational power mechanism, reducing the cost of the device and lowering energy consumption.

[0027] 2. This utility model, by comprising a worm gear, a worm shaft, a connecting shaft, and multiple sets of upper printing molds, allows for the printing of different content on the precious metal side. The operator can rotate the worm shaft, which in turn causes the worm gear to rotate, thus lowering the upper printing mold with the corresponding content. This allows for the printing of different content according to customer needs. The device also includes a magnetic block, a lower printing mold, a piston rod, a piston plate, and a piston chamber. When different content needs to be printed on the bottom surface of the precious metal, the operator can use a large magnetic block to lift the lower printing mold, separating it from the magnetic block. Then, a lower printing mold with the corresponding content can be placed on the magnetic block. This method facilitates the replacement of both the upper and lower printing molds, making the device more convenient and increasing its functionality and applicability. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1: A collectible stamping device, such as Figures 1-7As shown, the device includes a workbench 1, with a fixed frame 2 on top. Chip discharge ports 10 and material discharge ports 12 are located on both sides of the workbench 1. Chip discharge ports 10 facilitate the discharge of chips, while material discharge ports 12 facilitate the discharge of precious metals. A hydraulic rod 3 is mounted on the top of the fixed frame 2, and a mounting plate 4 is fixed to the output end of the hydraulic rod 3. Sliding rods 5 are fixed on both sides of the top of the workbench 1, and the mounting plate 4 slides with the sliding rods 5. Under the action of the sliding rods 5, the vertical displacement of the mounting plate 4 is more stable. A fixed plate 6 is located at the bottom of the mounting plate 4, and a connecting shaft 22 is mounted on the inner side of the fixed plate 6. An upper printing mold 24 is fixed to the outer surface of the connecting shaft 22 via a fixed rod 23. Four sets of upper printing molds 24 are arranged in a ring shape on the outer surface of the connecting shaft 22. Rotation of the connecting shaft 22 allows the four sets of upper printing molds to move. The mold 24 can rotate, and the rotation of the four sets of upper printing molds 24 facilitates replacement according to the printing requirements. One end of the connecting shaft 22 is fixed with a worm gear 31. The back of the fixing plate 6 is equipped with a worm 32. The back of the mounting plate 4 is fixed with a toothed rod 25. The inside of the worktable 1 is equipped with a rotating shaft 27 and a guide plate 11. The outer surface of the rotating shaft 27 is equipped with a rotating frame 7 and a pawl 34. A spring 30 is installed on the inner side of the pawl 34. The inside of the rotating frame 7 is equipped with a piston chamber 19. The inside of the piston chamber 19 is equipped with a piston plate 20. A piston rod 17 is fixed on the piston plate 20. One end of the piston rod 17 is fixed with a lower printing mold 21 by a magnetic block 35. The back of the worktable 1 is equipped with a rotating cylinder 28 by a mounting ring 26. The outer surface of the rotating cylinder 28 is equipped with a toothed ring 29. The inner wall of the rotating cylinder 28 is fixed with a ratchet 33.

[0039] See Figure 2 In the above embodiment, the top side of the guide plate 11 has several filter holes, which facilitate the filtration of the cleaning water and thus facilitate the recycling of the cleaning water.

[0040] See Figure 1 In the above embodiment, the outer surface of the workbench 1 is equipped with a control panel 8, and the hot air blower 9, water pump 14 and hydraulic rod 3 are all electrically connected to the control panel 8. The operator can easily control the hot air blower 9, water pump 14 and hydraulic rod 3 through the control panel 8.

[0041] See Figures 1-3 In the above embodiment, the bottom of the workbench 1 is fixed with a support leg 13, and the bottom of the support leg 13 is provided with a shock-absorbing pad. The support leg 13 can support the workbench 1, and the shock-absorbing pad can make the workbench 1 more stable and play a certain role in shock absorption.

[0042] See Figure 3 and Figure 5In the above embodiment, a knob is fixed at the bottom end of the worm gear 32, which allows the operator to easily rotate the worm gear 32, making the rotation of the worm gear 32 more convenient.

[0043] Example 2: To facilitate cleaning of the lower mold, Example 2 is an improvement on Example 1. (See attached document for details.) Figure 1 , Figure 2 and Figure 6 A water pump 14 is installed inside the lower part of the workbench 1, and the water outlet of the water pump 14 is connected to multiple rinsing heads 16 through a water supply pipe 15. The water pump 14 can draw cleaning water, which is sprayed out through the water supply pipe 15 and the rinsing heads 16. The sprayed cleaning water can rinse the lower mold 21. A hot air blower 9 is installed on the upper side of one side of the workbench 1, and the air outlet of the hot air blower 9 is connected to a hot air nozzle 18. The hot air generated by the hot air blower 9 is sprayed out through the hot air nozzle 18, which can dry the lower mold 21.

[0044] The implementation principle of this utility model is as follows: First, if the operator needs to imprint different content according to the type of precious metal, the operator can replace the upper imprint mold 24 and the lower imprint mold 21. During replacement, the operator can rotate the worm gear 32. The rotation of the worm gear 32 causes the worm wheel 31 to drive the connecting shaft 22 to rotate, thereby causing the upper imprint mold 24 with the corresponding content to face downwards, so that different content can be imprinted according to customer needs. At the same time, a magnetic block 35, a lower imprint mold 21, a piston rod 17, a piston plate 20, and a piston chamber 19 are also provided. When different content needs to be imprinted on the bottom surface of the precious metal, the operator can use a larger magnetic block 35 to pick up the lower imprint mold 21, thereby separating the lower imprint mold 21 from the magnetic block 35. Then, a lower imprint mold 21 with the corresponding content can be placed on the magnetic block 35. Then, the operator places the precious metal on the lower imprint mold 21 and then starts the hydraulic rod 3. When the hydraulic rod 3 pushes the mounting plate 4 downwards, the gear 25 will engage with the gear ring 2. 9. Engagement causes the rotating drum 28 to rotate. At this time, the ratchet 33 and pawl 34 are not under stress, so the rotating drum 28 idles. The upper mold 24 and lower mold 21 can then imprint the precious metal. After imprinting, the rack 25 moves upward, which causes the gear ring 29 and the rotating drum 28 to reverse. At this time, the ratchet 33 and pawl 34 are under stress, and the rotation of the rotating drum 28 causes the rotating shaft 27 to rotate, thereby causing the rotating frame 7 to rotate 90°. This causes the imprinted precious metal to fall onto the guide plate, while the imprinting groove on the other rotating frame 7 faces upwards, making it easier to place the next precious metal. The imprinted precious metal will fall onto the guide plate 11 and then be discharged from the guide plate 11. At this time, the operator can start the water pump 14 and the hot air blower 9. The water pump 14 uses the water pipe 15 and the cleaning head to rinse the lower mold 21. After rinsing, the filter hole filters the cleaning water, and the hot air blower 9 dries the lower mold 21.
