Description

Technical Field

[0001] This utility model relates to the field of pad printing technology, specifically to a pad printing ink-drying mechanism for a pad printing pad. Background Technology

[0002] A pad printing machine is an ink printing device. It typically consists of a pad printing head and a heating chamber. The pad printing head absorbs ink from a steel plate by compressing and deforming, then transfers the ink to the surface of the substrate. The heating chamber heats the pad printing head. Pad printing machines are suitable for printing on plastics, toys, glass, metals, ceramics, electronics, IC packaging, etc., and have become a primary device for printing and decorating various object surfaces.

[0003] Traditional pad printing machines heat the printing pad as follows: 1. A centralized heating box is used, and hot air is transmitted to the printing pad area through a long pipeline. However, the hot air is lost during transmission. For example, if the heating box is set to 100°C, the actual temperature when it reaches the printing pad is only about 60°C. Therefore, in order to achieve the target temperature, the set temperature of the heating box needs to be increased, which leads to a significant increase in power consumption. 2. The continuous heat release from the heating box will cause the ambient temperature inside the printing chamber to rise continuously. Since ink is sensitive to temperature, large fluctuations in ambient temperature directly affect the stability of product quality. 3. The PTC heating element used has a short lifespan and is prone to short circuit risk due to high-temperature aging.

[0004] Therefore, how to provide an ink-drying mechanism for pad printing is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide an ink drying mechanism for pad printing heads, aiming to solve the aforementioned technical problems. This invention avoids the use of traditional centralized heating and pipeline transmission modes, and instead proposes a distributed, near-field, on-demand heating solution. Each pad printing head is equipped with an independent, integrated heating unit, i.e., it has an upper drying structure and a lower drying structure, which are directly installed near the working position of the pad printing head, greatly shortening the hot air transmission path and fundamentally eliminating pipeline heat loss. The head blowing and product blowing are completely isolated from each other to avoid mutual interference. At the same time, three heating rods in parallel mode are used, which significantly improves safety and reliability. It also adopts constant temperature start-stop control, which greatly reduces ineffective energy consumption.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A pad printing ink-drying mechanism includes a base, a pad printing head device, a drying component, a Y-axis moving structure, an X-axis moving structure, and a product placement component. The pad printing head device is fixed on a pad printing head support on one side, and the pad printing head support is fixed on the base below. One end of the Y-axis moving structure is connected to the pad printing head support, and the other end of the Y-axis moving structure is connected to the drying component. The drying component is located below the pad printing head device.

[0008] The X-axis moving structure is mounted on the base, and one end of the X-axis moving structure is connected to the product placement component, which is located below the drying component.

[0009] The drying assembly includes an upper drying structure and a lower drying structure, which are independently arranged. The air outlet of the upper drying structure is directed towards the pad printing head device, and the air outlet of the lower drying structure is directed towards the product placement assembly. This invention improves upon the traditional heating method by using independent unit rapid heating. After the pad printing head device picks up ink, it enters the upper drying structure, where it blows hot air onto the ink in the pad printing head device to dry the ink surface. Meanwhile, the lower drying structure dries the surface of the product.

[0010] As a preferred technical solution of this utility model, the upper drying structure includes an upper drying box and a plurality of upper drying vent plates and a plurality of upper heating rods installed inside the upper drying box. The upper drying vent plates are located above the upper heating rods. One end of the upper heating rod extends outward through the upper drying box. The upper end of the upper drying box is provided with an upper air blowing hole. The lower end of the upper drying box is connected to the lower drying structure. The upper drying box is provided with an upper air inlet installation channel and a plurality of upper air inlets.

[0011] As a preferred technical solution of this utility model, the upper drying structure further includes several upper air inlet pipes and several upper throttle valves. One end of the upper air inlet pipe is installed in the upper air inlet mounting channel. The upper air inlet pipe is provided with several upper through holes, and the upper through holes are connected to the upper air inlet holes.

[0012] As a preferred technical solution of this utility model, the lower drying structure includes a lower drying box and a plurality of lower drying vent plates and a plurality of lower heating rods installed inside the lower drying box. The lower drying vent plates are located below the lower heating rods. One end of the lower heating rod extends outward through the lower drying box. The lower end of the lower drying box is provided with a lower air blowing hole. The upper end of the lower drying box is connected to the upper drying box. The lower drying box is provided with a lower air inlet installation channel and a plurality of lower air inlets.

[0013] As a preferred technical solution of this utility model, the lower drying structure further includes several lower air inlet pipes and several lower throttle valves. One end of the lower air inlet pipe is installed in the lower air inlet mounting channel, and several lower through holes are provided below the lower air inlet pipe, which communicate with the lower air inlet.

[0014] As a preferred technical solution of this utility model, the Y-axis moving structure includes a Y-axis driving cylinder, a push side seat, a push support seat, a Y-axis guide rod, and a Y-axis guide block. The Y-axis guide block is fixed on the pad printing head support seat. One end of the Y-axis guide rod movably passes through the Y-axis guide block and connects to the push side seat. One end of the push side seat is connected to the output end of the Y-axis driving cylinder. The other end of the push side seat is connected to the push support seat. The upper end of the push support seat is connected to the upper drying oven.

[0015] As a preferred embodiment of this utility model, the X-axis moving structure includes an X-axis rodless cylinder, an X-axis slider is provided on the X-axis rodless cylinder, and the upper end of the X-axis slider is connected to the product placement assembly.

[0016] As a preferred embodiment of this utility model, the upper end of the product placement component is provided with a product placement platform.

[0017] As a preferred embodiment of this utility model, the upper air intake pipe is made of nylon or Teflon, and the lower air intake pipe is made of nylon or Teflon.

[0018] The ink-drying mechanism for pad printing inkjet heads of this utility model has the following beneficial effects:

[0019] 1. Independent unit design: The ink drying mechanism for pad printing pads is equipped with an independent and integrated heating unit (i.e., upper drying box and lower drying box) for each pad printing pad nozzle. It is directly installed near the working position of the pad printing pad, which greatly shortens the hot air transmission path and fundamentally avoids heat loss from the pipeline.

[0020] 2. Long service life: The ink drying mechanism for pad printing pads of this utility model uses high-performance mold upper and lower heating rods to replace the traditional PTC heating element. The PTC heating element has a long service life, avoids the risk of high temperature short circuit, and adopts a three-parallel connection mode, which significantly improves safety and reliability.

[0021] 3. Energy consumption is significantly reduced. The ink drying mechanism for pad printing pads in this utility model changes the traditional mode of "the heating box is always on after the equipment is started" to an intermittent operation mode of "the heating unit maintains a constant temperature at a set value and is only turned on when the pad needs to be blown", thus reducing ineffective energy consumption.

[0022] 4. Optimization of air duct and pipeline: The ink drying mechanism for pad printing head of this utility model has optimized the internal air duct structure of the heating chamber to ensure that hot air blows evenly on the surface of the pad printing head. The single air inlet pipeline has been changed to a dual pipeline, and a throttle valve has been added to achieve precise and flexible adjustment of the air speed to adapt to different ink and process requirements.

[0023] 5. Improve equipment lifespan and safety. The ink drying mechanism for pad printing pads has upgraded the air tube from a 60℃-resistant PU tube to a nylon or Teflon tube with a temperature resistance of over 120℃, thus comprehensively improving the durability and long-term stability of the equipment.

[0024] 6. Modular adaptable design: The structure and size of the drying component of this pad printing pad ink-collecting and drying mechanism can be customized according to different models, different pad shapes and product structures to achieve precise matching;

[0025] 7. Good temperature stability: The ink drying mechanism of this pad printing head completely isolates the pad printing head blower and the product blower from above and below to avoid mutual interference. The close-range heating design of the independent heating unit reduces heat transfer loss and prevents the ambient temperature inside the printing chamber from rising continuously, thus ensuring stable ink performance.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the product of this utility model will be further described in detail below with reference to the embodiments and accompanying drawings.

[0035] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element; when an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] like Figure 1 and Figure 3 As shown, a pad printing ink drying mechanism includes a base 1, a pad printing ink head device 2, a drying component 3, a Y-axis moving structure 4, an X-axis moving structure 5, and a product placement component 6. The pad printing ink head device 2 is fixed on a pad printing ink head support 7 on one side, and the pad printing ink head support 7 is fixed on the base 1 below. One end of the Y-axis moving structure 4 is connected to the pad printing ink head support 7, and the other end of the Y-axis moving structure 4 is connected to the drying component 3. The drying component 3 is located below the pad printing ink head device 2.

[0038] The X-axis moving structure 5 is mounted on the base 1, and one end of the X-axis moving structure 5 is connected to the product placement component 6, which is located below the drying component 3.

[0039] The drying assembly 3 includes an upper drying structure 8 and a lower drying structure 9 that are independently arranged. The air outlet of the upper drying structure 8 is arranged towards the pad printing head device 2, and the air outlet of the lower drying structure 9 is arranged towards the product placement assembly 6.

[0040] It should be noted that previous heating boxes were in full-time heating mode, resulting in a lot of ineffective energy consumption. However, this utility model adopts a constant temperature start-stop design, which uses constant temperature start-stop control: the system only starts the heating and blowing functions of the corresponding unit when it detects that the pad printing head 33 has picked up ink and needs to be dried, and stops after the work is completed, which greatly reduces ineffective energy consumption.

[0041] It should be further explained that traditional heating boxes continuously output heat, requiring the installation of exhaust mechanisms to prevent heat buildup inside the equipment. This new invention, however, reduces unnecessary heat output, helping to maintain a stable temperature inside the printing chamber and thus ensuring product quality.

[0042] This invention employs a close-range heating design with independent heating units, specifically an upper drying structure 8 and a lower drying structure 9 that are independently set up. Each or each group of pad printing heads 33 is equipped with an independent, integrated heating unit, which is directly installed near the working position of the pad printing head 33. This greatly shortens the hot air transmission path, fundamentally reduces heat loss from pipelines and heat transmission, prevents the ambient temperature inside the printing chamber from continuously rising, and ensures stable ink performance.

[0043] like Figure 4 and Figure 5 As shown, the upper drying structure 8 includes an upper drying chamber 10 and several upper drying vent plates 11 and several upper heating rods 12 installed inside the upper drying chamber 10. The upper drying vent plates 11 are located above the upper heating rods 12. One end of the upper heating rods 12 extends outward through the upper drying chamber 10. The upper end of the upper drying chamber 10 is provided with an upper air blowing hole 13. The lower end of the upper drying chamber 10 is connected to the lower drying structure 9. The upper drying chamber 10 is provided with an upper air inlet installation channel and several upper air inlets 14.

[0044] like Figure 4 and Figure 5As shown, the upper drying structure 8 also includes several upper air inlet pipes 15 and several upper throttle valves 16. The upper air inlet pipes 15 are installed in the upper air inlet mounting channel, and several upper through holes are provided on the upper air inlet pipes 15, which communicate with the upper air inlet holes 14. One end of the upper throttle valve 16 is connected to the upper air inlet pipe 15, and the other end can be connected to an external air blowing pipe. In this embodiment, there are six upper air inlet pipes 15, that is, three are distributed side by side on the left and right sides, changing from the traditional single-path to a double-path.

[0045] like Figure 4 and Figure 5 As shown, the lower drying structure 9 includes a lower drying chamber 17 and several lower drying vent plates 18 and several lower heating rods 19 installed inside the lower drying chamber 17. The lower drying vent plates 18 are located below the lower heating rods 19. One end of the lower heating rod 19 extends outward through the lower drying chamber 17. The lower end of the lower drying chamber 17 is provided with a lower air blowing hole. The upper end of the lower drying chamber 17 is connected to the upper drying chamber 10. The lower drying chamber 17 is provided with a lower air inlet installation channel and several lower air inlets.

[0046] It should be noted that this utility model avoids the use of traditional PTC heating elements (with a service life of only about 2000 hours), and instead uses imported S-grade mold heating rods (usually 6X100 specification, 220V voltage, 250W per rod, with a service life of up to 8000 hours). That is, it is equipped with an upper heating rod 12 and a lower heating rod 19, and adopts a three-rod parallel connection (total power of about 750W), which significantly improves safety and reliability and provides good performance.

[0047] like Figure 4 and Figure 5 As shown, the lower drying structure 9 also includes several lower air inlet pipes and several lower throttle valves 20. The lower air inlet pipes are installed in the lower air inlet mounting channel, and several lower through holes are provided at the bottom of the lower air inlet pipes, which communicate with the lower air inlet holes. One end of each lower throttle valve 20 is connected to the lower air inlet pipe, and the other end can be connected to an external blowing pipe. In this embodiment, there are six lower air inlet pipes, that is, three are arranged side by side on the left and right sides, changing from the traditional single-path to a double-path.

[0048] like Figure 4 and Figure 5 As shown, the upper air intake pipe 15 is made of nylon or Teflon, and the lower air intake pipe is made of nylon or Teflon.

[0049] It should be noted that traditional air intake pipes use PU air pipes that are resistant to 60°C, while the upper air intake pipe 15 and the lower air intake pipe of this utility model both use nylon high-temperature resistant pipes or Teflon high-temperature resistant pipes that are resistant to 120°C or higher, which results in better performance and extends the service life of this utility model.

[0050] The air intake pipe of this utility model has been changed from a "single PU pipe with an outer diameter of 12mm and an inner diameter of 8mm" to a "dual air intake pipe with an outer diameter of 8mm and an inner diameter of 5mm". The single-path has been changed to a dual-path, and its total inner diameter circular area has been adjusted from 50.3mm² to 19.6mm²×2. Under the same air source, the air intake volume is larger. The internal air duct has been re-optimized to ensure more uniform air blowing and to meet the production requirements of mass production models. At the same time, an upper throttle valve 16 and a lower throttle valve 20 are set to adjust the wind speed. The internal air duct has been re-optimized to ensure more uniform air blowing and to meet the production requirements of mass production models.

[0051] like Figure 2 and Figure 3 As shown, the Y-axis moving structure 4 includes a Y-axis drive cylinder 21, a push side seat 22, a push support seat 23, a Y-axis guide rod 24, and a Y-axis guide block 25. The Y-axis guide block 25 is fixed to the pad printing head support seat 7 via a connecting plate. One end of the Y-axis guide rod 24 movably passes through the Y-axis guide block 25 and connects to the push side seat 22. One end of the push side seat 22 is connected to the output end of the Y-axis drive cylinder 21, and the other end of the push side seat 22 is connected to the push support seat 23. The upper end of the push support seat 23 is connected to the upper drying chamber 10. The Y-axis moving structure 4 is used to drive the drying assembly 3 to move.

[0052] like Figure 6 As shown, the X-axis moving structure 5 includes an X-axis rodless cylinder 26, on which an X-axis slider 27 is provided. The upper end of the X-axis slider 27 is connected to the product placement assembly 6. In this embodiment, the X-axis rodless cylinder 26 can be a magnetically coupled rodless cylinder or a mechanically coupled rodless cylinder. The X-axis moving structure 5 is used to move and adjust the position of the product.

[0053] like Figure 6 As shown, the product placement assembly 6 includes a product placement platform 28. The product placement platform 28 can be a vacuum adsorption platform used to adsorb and place products to be sprayed with ink. The product placement platform 28 in this embodiment is prior art, so it will not be described in detail here.

[0054] like Figure 6 As shown, the product placement assembly 6 also includes a CCD correction device 29 for detecting and correcting the position of the product. The CCD correction device 29 is existing technology, so it will not be described in detail here.

[0055] like Figure 2 and Figure 3 As shown, the pad printing head support 7 is also provided with a movable opening in the steel plate.

[0056] like Figure 2 and Figure 3As shown, it also includes a steel plate 30 and a steel plate driving cylinder 31. One end of the steel plate driving cylinder 31 is connected to a connecting plate, and the output end of the steel plate driving cylinder 31 is connected to the steel plate 30. The steel plate 30 is movably disposed within a movable opening in the steel plate. The steel plate driving cylinder 31 can drive the steel plate 30 to move along the Y-axis. The steel plate driving cylinder 31 can be replaced with a steel plate driving motor. The steel plate 30 is used to hold pattern ink.

[0057] like Figure 1 and Figure 2 As shown, the pad printing head device 2 includes a head driving cylinder 32 and a pad printing head 33. The output end of the head driving cylinder 32 is connected to the pad printing head 33. The head driving cylinder 32 can be replaced by a head driving motor. The pad printing head device 2 in this embodiment is prior art, so it will not be described in detail here.

[0058] It should be noted that the size of the pad printing pad device 2 in this embodiment can be adjusted according to actual needs to adapt to round or irregularly shaped pads;

[0059] The structure and dimensions of the upper drying structure 8 and the lower drying structure 9 in this embodiment can be customized according to different machine models, different pad shapes (such as round, irregularly shaped pads, etc.) and product structures to achieve precise matching, facilitate modular adaptation design, and provide high flexibility. That is, if the space in the pad printing equipment allows, it can be modified and applied to different pad printing equipment, demonstrating strong adaptability.

[0060] like Figures 1 to 6 As shown, the heating operation mode of the pad printing head of this utility model is as follows:

[0061] 1. The robot places the product on the product placement platform 28, and the CCD correction device 29 detects and corrects the position of the product;

[0062] 2. The pattern extends out of the steel plate 30, and then the printing head 33 removes the pattern ink from the steel plate 30, and the steel plate 30 is reset;

[0063] 3. The Y-axis moving structure 4 drives the upper drying box 10 and the lower drying box 17 to move, and the pad printing head 33 enters the upper drying box 10 to dry the ink;

[0064] 4. The pad printing head 33 transfers the ink onto the product, and the product is dried in the drying oven 17.

[0065] 5. The robot picks up the printed product.

[0066] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
