Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot stamping equipment technology, and in particular to a hot stamping device for packaging paperboard. Background Technology
[0002] In the production process of packaging paperboard, hot stamping is widely used as an important decoration and marking method. It can add exquisite patterns, text or trademarks to the surface of packaging paperboard, enhance the visual effect and added value of the product. As the market's requirements for the appearance quality of packaging paperboard continue to increase, higher standards are also being set for the performance of hot stamping equipment.
[0003] Existing technologies have the following problems:
[0004] After extensive searching, it was found that the patent document with application number CN202223234723.7 discloses a surface hot stamping device for packaging carton production. This patent uses an adjustment component to drive the hot stamping head to move and adjust, and uses the hot stamping head to perform hot stamping treatment on the surface of the carton, thereby realizing the hot stamping treatment that is easy to move and adjust.
[0005] Based on the aforementioned patents, it was found that existing patents still have some problems in practical use. One significant issue is the lack of stability in some hot stamping devices. Although many hot stamping devices are equipped with moving mechanisms, such as casters, to facilitate transport, these mechanisms may cause unnecessary displacement due to uneven ground or vibrations during operation. Even if some devices use simple support structures to increase stability, the effect is not ideal. This leads to deviations in the hot stamping position, seriously affecting the quality of hot stamping, increasing the scrap rate, and raising production costs. On the other hand, the cardboard is not properly secured when hot stamping packaging paperboard. Existing hot stamping devices often simply place the cardboard on the worktable without effective pre-fixing measures. At the moment the hot stamping head presses down, the cardboard is prone to displacement due to pressure. This displacement also causes inaccurate positioning of the hot stamped pattern or text, affecting the overall quality and aesthetics of the product.
[0006] To address these shortcomings, we have proposed a hot stamping device for packaging paperboard. Utility Model Content
[0007] The purpose of this invention is to provide a hot stamping device for packaging paperboard in order to overcome the shortcomings of existing technologies.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: a hot stamping device for packaging cardboard, comprising a base, an adjustment seat installed on the top of the base, and an adjustment frame fixedly installed on one side of the adjustment seat. A support plate is welded to the bottom surface of the adjustment frame, and a hot stamping head is fixedly installed on the bottom surface of the support plate. A storage groove is formed on the bottom surface of the base, and a locking plate is slidably connected inside the storage groove. A guide rod and a threaded cylinder are welded to the top surface of the locking plate. A drive motor is fixedly installed on the top surface of the base, and a threaded column is installed in the storage groove at the output end of the drive motor. The threaded column and the threaded cylinder are used in conjunction. A guide groove is formed inside the base, and the guide rod is slidably connected to the guide groove. A sliding rod is provided through the surface of the support plate, and a limit block and a fixing frame are respectively installed at the upper and lower ends of the sliding rod. A clearance hole for use with the hot stamping head is formed on the surface of the fixing frame. A spring is sleeved between the support plate and the fixing frame on the outside of the sliding rod.
[0009] Preferably, the bottom surface of the base is fixedly equipped with self-locking casters, and there are multiple self-locking casters, which are evenly distributed at the four corners of the bottom surface of the base.
[0010] Preferably, a control switch is fixedly installed on the outer wall of the base, and the control switch is electrically connected to the drive motor through a wire.
[0011] Preferably, the lengths of the threaded column, threaded cylinder, and guide rod are all greater than the height of the self-locking caster wheel.
[0012] Preferably, the cross-sectional area of the relief hole is larger than the cross-sectional area of the hot stamping tip.
[0013] Preferably, the thickness of the fixing frame is less than the height of the hot stamping tip.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. In this utility model, by setting a locking plate on the base, after the hot stamping device moves to the working position, the locking plate can extend from the storage groove and make close contact with the ground, increasing the friction and support area between the hot stamping device and the ground. Even if the ground is uneven or vibration occurs during operation, it can effectively prevent the device from moving excessively, ensuring the stability of the device during the hot stamping process, thereby improving the accuracy of hot stamping, reducing the hot stamping position deviation caused by device movement, reducing the scrap rate, and improving production efficiency.
[0016] 2. The fixing frame set below the hot stamping head in this utility model can pre-fix the packaging cardboard before hot stamping. The fixing frame can automatically adjust the clamping force according to the thickness of the cardboard through the cooperation of the sliding rod and spring. When the hot stamping head is pressed down, the fixing frame can effectively limit the displacement of the cardboard, ensure the positional accuracy of the hot stamping pattern and text, improve the hot stamping quality of the packaging cardboard, and meet the market demand for high-quality packaging cardboard.

[0026] Please refer to Figure 1-4 A hot stamping device for packaging cardboard includes a base 1, an adjusting seat 2 mounted on top of the base 1, and an adjusting frame 3 fixedly mounted on one side of the adjusting seat 2. A support plate 4 is welded to the bottom surface of the adjusting frame 3, and a hot stamping head 5 is fixedly mounted on the bottom surface of the support plate 4. A storage groove 12 is formed on the bottom surface of the base 1, and a locking plate 8 is slidably connected inside the storage groove 12. A guide rod 14 and a threaded cylinder 11 are welded to the top surface of the locking plate 8. A drive motor 9 is fixedly mounted on the top surface of the base 1, and the output end of the drive motor 9... A threaded post 10 is installed inside the storage slot 12, and the threaded post 10 is used in conjunction with the threaded cylinder 11. A guide groove 13 is opened inside the base 1, and the guide rod 14 is slidably connected to the guide groove 13. A slide rod 17 is provided through the surface of the support plate 4, and a limit block 18 and a fixing frame 15 are respectively installed at the upper and lower ends of the slide rod 17. A clearance hole 16 is opened on the surface of the fixing frame 15 to cooperate with the hot stamping head 5. A spring 19 is sleeved on the outside of the slide rod 17 between the support plate 4 and the fixing frame 15.
[0027] First, the device is moved to the desired working position using the self-locking casters 7. Then, the drive motor 9 is operated to rotate in both directions. The drive motor 9 drives the threaded column 10 to rotate. Under the limiting action of the guide rod 14 and the guide groove 13, the rotational motion is converted into linear motion, driving the threaded cylinder 11 to rise and fall. This causes the locking plate 8 to extend downwards and make close contact with the ground, fixing the hot stamping device in place. This increases the friction and support area between the hot stamping device and the ground, effectively preventing unnecessary movement of the device even on uneven ground or during operation, ensuring the stability of the device during the hot stamping process, thereby improving the hot stamping efficiency. To ensure accuracy, reduce hot stamping position deviation caused by device movement, lower scrap rate, and improve production efficiency, the packaging cardboard is placed on the worktable. At this time, the fixing frame 15 presses the cardboard downward under the action of the spring 19, completing the pre-fixation of the cardboard. According to the thickness of the packaging cardboard, the height of the adjusting seat 2 is then adjusted to adjust the height of the hot stamping head 5 to a suitable position. After everything is ready, the hot stamping program is started, and the hot stamping head 5 performs hot stamping operation on the packaging cardboard. During the entire hot stamping process, the locking plate 8 ensures that the device will not move, and the fixing frame 15 ensures that the cardboard will not shift, thereby achieving precise and high-quality hot stamping work.
[0028] In this implementation scheme: a self-locking caster wheel 7 is fixedly installed on the bottom surface of the base 1, and there are multiple self-locking caster wheels 7, which are evenly distributed at the four corners of the bottom surface of the base 1.
[0029] Specifically, it improves the convenience of mobile hot stamping equipment, enabling it to be moved to a suitable location for hot stamping operations.
[0030] In this embodiment: a control switch 6 is fixedly installed on the outer wall of the base 1, and the control switch 6 is electrically connected to the drive motor 9 through a wire.
[0031] Specifically, the common circuit connection structure will not be elaborated on here.
[0032] In this implementation scheme: the lengths of the threaded column 10, the threaded cylinder 11, and the guide rod 14 are all greater than the height of the self-locking caster wheel 7.
[0033] Specifically, this allows the locking plate 8 to be completely removed from the storage slot 12 and make contact with the ground.
[0034] In this implementation plan, the cross-sectional area of the clearance hole 16 is larger than the cross-sectional area of the hot stamping head 5.
[0035] Specifically, this allows the hot stamping head 5 to contact the cardboard through the clearance hole 16 and perform hot stamping.
[0036] In this implementation plan: the thickness of the fixing frame 15 is less than the height of the hot stamping head 5.
[0037] Specifically, this ensures that the hot stamping head 5 can contact the cardboard through the clearance hole 16 and perform hot stamping.
[0038] Working Principle: In use, the device is first moved to the desired working position using the self-locking casters 7. Then, the drive motor 9 is operated to rotate in both directions. The drive motor 9 drives the threaded column 10 to rotate. Under the limiting action of the guide rod 14 and guide groove 13, the rotational motion is converted into linear motion, driving the threaded cylinder 11 to rise and fall. This causes the locking plate 8 to extend downwards and make close contact with the ground, fixing the hot stamping device in place. This increases the friction and support area between the hot stamping device and the ground, effectively preventing unnecessary movement of the device even on uneven ground or during operation, ensuring the stability of the device during the hot stamping process. To improve the accuracy of hot stamping, reduce the deviation in hot stamping position caused by device movement, lower the scrap rate, and improve production efficiency, the packaging cardboard is placed on the worktable. At this time, the fixing frame 15 presses the cardboard downward under the action of the spring 19, completing the pre-fixation of the cardboard. According to the thickness of the packaging cardboard, the height of the adjusting seat 2 is then adjusted to adjust the height of the hot stamping head 5 to a suitable position. After everything is ready, the hot stamping program is started, and the hot stamping head 5 performs hot stamping operation on the packaging cardboard. Throughout the hot stamping process, the locking plate 8 ensures that the device will not move, and the fixing frame 15 ensures that the cardboard will not shift, thereby achieving precise and high-quality hot stamping work.
[0039] It should be noted that, as shown in the attached diagram of the instruction manual, the adjusting seat 2 can be raised and lowered, and the adjusting frame 3 can be moved horizontally. The adjustment method, structure and working principle of the adjusting seat 2 and the adjusting frame 3 are the same as the lifting principle of the locking plate 8, and will not be described in detail here.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
