Description

Technical Field

[0001] This utility model relates to the field of printer platform technology, specifically to a platform specifically designed for printers. Background Technology

[0002] In existing inkjet printing equipment, a platen structure is typically included to support and position the printing paper. The primary function of this platen is to provide a flat support surface, allowing the paper to move or be positioned stably under the printhead for image printing. However, traditional platen designs are relatively simple, offering only basic support and lacking an effective mechanism for securing the paper. During printing, especially at high speeds or when the equipment is moving, the paper is prone to slight displacement or warping due to vibration, airflow disturbances, or the minute forces generated when the printhead sweeps across it. This positional shift directly leads to image distortion such as misalignment, ghosting, or blurring, severely impacting printing accuracy and yield.

[0003] Furthermore, current inkjet printing tables generally lack thermal management capabilities. During inkjet printing, ink is sprayed onto the paper surface in liquid form, and its drying and solidification rely on natural evaporation or external air drying, a relatively slow process. Since the printing table itself lacks cooling or accelerated curing structures, the wet ink requires a considerable amount of time to fully cure after printing, necessitating the transfer of printed parts to a dedicated drying area for post-processing. This not only extends the overall production cycle and increases the storage and handling of semi-finished products but also occupies additional production space, leading to low production efficiency and making it difficult to meet the demands of high-throughput continuous production.

[0004] In summary, the lack of paper adsorption and fixation functions and rapid ink cooling mechanisms in existing printer tabletops has become a technical bottleneck restricting the improvement of printing accuracy and production efficiency. There is an urgent need for a new tabletop structure that integrates adsorption and cooling functions to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dedicated printer platen to solve the problem of low production efficiency caused by the lack of paper adsorption and fixation function and rapid ink cooling mechanism in existing printer platens.

[0006] To solve the above-mentioned technical problems, this utility model achieves the following solution:

[0008] A table body, the upper surface of which is used to place printing paper;

[0009] An adsorption structure, the adsorption structure comprising a plurality of adsorption holes arranged in an array on the upper surface of the platform body;

[0010] A cooling structure, comprising a cooling pipe embedded in the main body of the platform, wherein the water in the cooling pipe regulates the temperature of the upper surface of the main body of the platform by heat transfer.

[0011] A suction device is provided to extract the gas inside the adsorption structure, thereby creating a negative pressure inside the suction hole.

[0015] The water circulation system includes a temperature sensor, a temperature controller, a heating module, and a cooling module. The temperature sensor is embedded in the main body of the platform to detect the real-time temperature of the main body of the platform and transmit the data to the temperature controller. The temperature controller controls the heating module or the cooling module to heat or cool the water entering the cooling pipe based on the real-time temperature detection data.

[0016] Preferably, the adsorption structure further includes a honeycomb plate disposed inside the main body of the platform and at least one air extraction hole disposed at the bottom of the main body of the platform. The honeycomb plate has multiple air chambers, and each air extraction hole is connected to one of the air chambers.

[0017] The inner wall of the air chamber is provided with multiple through holes, and two adjacent air chambers are connected to each other through the through holes;

[0018] The air extraction port is connected to at least one of the air chambers and is connected to the air extraction device through an external air pipe.

[0019] Preferably, the cooling pipes are disposed above the honeycomb panel and are bent and folded along the horizontal plane, with the cooling pipes arranged alternately between the matrix rows and columns formed by the arrangement of multiple suction holes.

[0020] Preferably, an air pipe connector is fixedly installed on the outside of the air extraction port, and the external air pipe is connected to the air pipe connector by a hose clamp;

[0021] The tracheal connector includes a tube body and a sub-plate disposed on the outside of the tube body. A rubber pad is disposed on the side of the sub-plate facing the lower surface of the main body of the platform. When the tracheal connector is installed outside the air extraction hole, the rubber pad is in close contact with the lower surface of the main body of the platform.

[0022] Preferably, at least four positioning windows are provided on one side of the platform body for shooting and positioning by the camera below the platform body;

[0023] The positioning window is a through hole that runs from the upper surface of the table body to the lower surface of the table body. When the position of the table body shifts, the camera passes through the positioning window to capture the position of the printed paper located on the upper surface of the table body, and transmits the captured data to the external main controller.

[0030] Compared with the prior art, the beneficial effects of this utility model are:

[0031] 1. Traditional printing plates only provide passive support and cannot prevent the slight displacement of the printing paper during dynamic printing. This solution integrates a negative pressure adsorption structure, which firmly adheres the printing paper to the upper surface of the printing plate throughout the entire printing area. This fundamentally avoids defects such as image misalignment, ghosting, or blurred edges caused by paper movement, significantly improving printing accuracy and yield.

[0032] 2. Existing equipment relies on natural evaporation or external air drying, resulting in long drying cycles and impacting continuous production capacity. This solution utilizes a built-in cooling pipe combined with a water circulation system to actively manage the heat of the printing platen and printing media, accelerating ink heat dissipation and promoting rapid cooling and setting. This not only reduces post-printing waiting time but also eliminates the need for additional drying processes and storage space, enabling simultaneous printing and curing, significantly improving overall production efficiency and equipment throughput.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0043] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0044] Example 1: The specific structure of this utility model is as follows:

[0045] like Figure 1 , Figure 5 , Figure 7 and Figure 8 As shown, a printer platform includes...

[0046] Table body 1, the upper surface of which is used to place printing paper;

[0047] Adsorption structure 2, the adsorption structure 2 includes a plurality of suction holes 21 arranged in an array on the upper surface of the platform body 1;

[0048] Cooling structure 3, the cooling structure 3 includes a cooling pipe 33 embedded in the platform body 1, the water in the cooling pipe 33 regulates the temperature of the upper surface of the platform body 1 by heat transfer;

[0049] The gas extraction device extracts the gas inside the adsorption structure 2, creating a negative pressure inside the suction hole 21. It should be noted that the gas extraction device can be a vacuum pump, a centrifugal fan, an electromagnetic gas extraction valve, etc.

[0050] Water circulation system 5 continuously replaces the water in the cooling structure 3.

[0051] In this embodiment, the upper surface of the platen body 1 is provided with an array of suction holes 21. These suction holes 21 are connected to internal air channels and to an air extraction device. When the printing paper is placed on the upper surface of the platen body 1, the air extraction device is activated. It extracts the gas from the internal space of the adsorption structure 2, creating a stable negative pressure at the suction holes 21. This negative pressure is transmitted to the bottom of the paper through the suction holes 21, using atmospheric pressure to firmly adsorb the paper onto the upper surface of the platen body 1, achieving uniform fixation over the entire area. This mechanism effectively suppresses paper slippage or edge warping caused by airflow disturbances, mechanical vibrations, or high-speed movement of the printhead.

[0052] Traditional printing platen 1 only provides passive support and cannot prevent the slight displacement of the printing paper during dynamic printing. This solution integrates a negative pressure adsorption structure 2, which firmly adheres the printing paper to the upper surface of the printing platen 1 throughout the entire printing area. This fundamentally avoids defects such as image misalignment, ghosting, or blurred edges caused by paper movement, and significantly improves printing accuracy and product yield.

[0053] A continuously arranged cooling pipe 33 is embedded inside the main body of the printing plate 1. Water flowing within the cooling pipe 33 acts as a heat exchange medium, continuously absorbing heat carried by the printing paper and the wet ink adhering to it on the upper surface of the main body 1 through heat conduction. A water circulation system 5 is connected to the cooling pipe 33, continuously injecting low-temperature water into the cooling pipe 33 and discharging heated water, maintaining the water temperature within the cooling pipe 33 at a low level. This ensures that the temperature of the upper surface of the main body 1 remains stable within a range conducive to rapid cooling and solidification of the ink. This process significantly shortens the transition time of liquid ink from spraying to curing, improving drying efficiency.

[0054] Existing equipment relies on natural evaporation or external air drying, resulting in long drying cycles and impacting continuous production capacity. This solution utilizes a built-in cooling pipe 33 combined with a water circulation system 5 to actively manage the heat of the printing platen 1 and the printing media, accelerating ink heat dissipation and promoting rapid cooling and setting. This not only reduces post-printing waiting time but also eliminates the need for additional drying processes and storage space, enabling simultaneous printing and curing, significantly improving overall production efficiency and equipment throughput.

[0055] like Figure 2As shown, the cooling structure 3 further includes a water inlet 31 and a water outlet 32. The water inlet 31 and the water outlet 32 ​​are located at the bottom of the platform body 1 and are respectively connected to both ends of the cooling pipe 33. The water inlet 31 and the water outlet 32 ​​are respectively connected to the water circulation system 5 through external water pipes. Water pipe connectors 34 are provided at both the water inlet 31 and the water outlet 32, and the water circulation system 5 is connected to the water pipe connectors 34 through external water pipes.

[0056] like Figure 8 As shown, the water circulation system 5 includes a temperature sensor 51, a temperature controller 52, a heating module 53, and a cooling module 54. The temperature sensor 51 is embedded in the platform body 1 to detect the real-time temperature of the platform body 1 and transmit the data to the temperature controller 52. The temperature controller 52 controls the heating module 53 or the cooling module 54 to heat or cool the water entering the cooling pipe 33 according to the real-time temperature detection data.

[0057] In this embodiment, during operation, the water circulation system 5 sends water of adjusted temperature into one end of the cooling pipe 33 through the water inlet 31. The water flows along a predetermined path in the cooling pipe 33, absorbing the heat from the main body 1 of the platen and the surface of the printing paper, and then returns to the water circulation system 5 from the other end through the water outlet 32, forming a closed or semi-closed circulation loop.

[0058] Temperature sensor 51 monitors the internal temperature of the printing platen 1 in real time and feeds the data back to temperature controller 52. Temperature controller 52 automatically determines whether to raise or lower the temperature based on a preset target temperature range, such as the optimal working temperature for a specific ink or paper type. When the temperature of the printing platen 1 is detected to be too high, such as in summer when the ambient temperature is high or continuous printing causes heat buildup, temperature controller 52 activates cooling module 54 to cool the circulating water, reducing the input water temperature and thus enhancing the cooling effect. When the ambient temperature is too low or when using certain special inks that require preheating and fixing, temperature controller 52 can activate heating module 53 to heat the circulating water, maintaining the printing platen at a suitable higher temperature to prevent the ink from solidifying too quickly or having insufficient adhesion. This closed-loop temperature control system enables on-demand adjustment and precise maintenance of the surface temperature of the printing platen 1, ensuring that the printing process is always in an optimal thermal environment.

[0059] like Figure 4As shown, the adsorption structure 2 further includes a honeycomb plate 22 disposed inside the platform body 1 and at least one air extraction hole 23 disposed at the bottom of the platform body 1. The honeycomb plate 22 has multiple air cavities 221, and each air extraction hole 21 is connected to one air cavity 221. Multiple through holes 2211 are opened on the inner wall of the air cavity 221, and two adjacent air cavities 221 are connected to each other through the through holes 2211. The air extraction hole 23 is connected to at least one air cavity 221 and is connected to the air extraction device through an external air pipe.

[0060] In this embodiment, a honeycomb panel 22 is provided inside the main body 1, which is composed of an array of multiple hexagonal, rectangular, or circular air cavities 221, forming a honeycomb-like porous structure. Each suction hole on the upper surface of the main body 1 corresponds to and connects to an independent air cavity 221, while adjacent air cavities 221 are interconnected through through-holes 2211 on their inner walls, forming a three-dimensional interconnected internal airflow network. This structure makes the entire adsorption area a uniformly distributed, interconnected negative pressure cavity system. When the air extraction device is activated, air is extracted from one or more air cavities 221 connected to it via an external air pipe connected to the air extraction hole 23 at the bottom of the main body 1. Since all air cavities 221 are interconnected through the through-holes 2211, the negative pressure rapidly diffuses throughout the honeycomb panel 22, establishing a stable low-pressure environment in all air cavities 221. Thus, a negative pressure is generated below each suction hole, firmly adsorbing and fixing the paper placed on the upper surface of the main body 1.

[0061] The honeycomb panel 22 not only serves as an airflow channel but also possesses excellent mechanical properties, enhancing the overall structural rigidity and deformation resistance of the main body 1. The design of the through holes 2211 allows for adjustment of airflow resistance and pressure equalization speed, preventing excessively strong or weak local vacuum. Since multiple air chambers 221 are interconnected through the through holes 2211, only one or a few suction holes 23 are needed to achieve negative pressure coverage of all suction holes 21, reducing the number and power requirements of the suction device.

[0062] Furthermore, such as Figure 6 and Figure 7 As shown, the cooling pipe 33 is disposed above the honeycomb panel 22 and is bent and folded along the horizontal plane. The cooling pipe 33 is arranged alternately between the matrix rows and columns formed by the array of multiple suction holes 21.

[0063] In this embodiment, the cooling pipes 33 are not simply buried at any location inside the main body 1, but are precisely positioned above the honeycomb panel 22, i.e., in the area near the upper surface of the main body 1. Simultaneously, the cooling pipes 33 are arranged in a curved and folded manner along the horizontal direction, such as in a serpentine, square, or multi-loop pattern, and are interwoven among the matrix rows and columns formed by the array of multiple suction holes 21. This means that the cooling pipes 33 avoid the path directly below each suction hole 21, but are tightly wrapped around the suction holes 21, forming a dense heat exchange network.

[0064] Because the cooling pipe 33 is in close contact with the upper surface of the platen body 1, its thermal resistance with the printing paper is minimal, enabling it to efficiently absorb the heat released by the paper and wet ink. When the water circulation system 5 drives the temperature-controlled water to flow within the cooling pipe 33, heat is rapidly conducted to the water through the metal pipe wall and carried away. Its serpentine folding design significantly extends the length of the cooling pipe 33 per unit area, increasing the contact area with the platen body 1, thereby improving the overall heat exchange efficiency.

[0065] The cooling pipes 33 are arranged in the gaps between the rows and columns of the suction hole matrix 21, which prevents the cooling pipes 33 from passing directly through the air cavity 221 or through hole 2211 area below the suction hole 21, thus not interfering with the connectivity and sealing of the airflow channel inside the honeycomb panel 22, and ensuring the normal operation of the negative pressure adsorption system.

[0066] Furthermore, an air pipe connector 24 is fixedly installed on the outside of the air extraction hole 23, and the external air pipe is connected to the air pipe connector 24 through a hose clamp; the air pipe connector 24 includes a pipe body 241 and a sub-plate 242 disposed on the outside of the pipe body 241. A rubber pad 2421 is disposed on the side of the sub-plate 242 facing the lower surface of the platform body 1. When the air pipe connector 24 is installed outside the air extraction hole 23, the rubber pad 2421 is tightly fitted to the lower surface of the platform body 1.

[0067] In this embodiment, the endotracheal connector 24 consists of a tube body 241 and a secondary plate 242. The tube body 241 is inserted into the suction port 23 and communicates with the internal air chamber 221. The external endotracheal tube is sleeved on the outer wall of the tube body 241 and secured with a hose clamp to ensure that the endotracheal tube will not fall off or leak air. The secondary plate 242 is fixed to the outside of the tube body 241 and extends in a flange shape. A rubber pad 2421 is provided on the side facing the lower surface of the platform body 1. When the endotracheal connector 24 is installed into the suction port 23, the secondary plate 242 drives the rubber pad 2421 to press against the lower surface of the platform body 1, forming a surface contact seal.

[0068] During installation, align the tube body 241 of the air hose connector 24 with and insert it into the suction hole 23 until the rubber gasket 2421 on the auxiliary plate 242 is completely flush with the lower surface of the platform body 1. Then tighten the hose clamp to securely connect the external air hose to the tube body 241. At this time, the rubber gasket 2421 undergoes slight elastic deformation under the pressure of the auxiliary plate 242, filling the tiny gap between the air hose connector 24 and the platform body 1, effectively blocking the path of gas leakage from around the suction hole 23. The entire connection structure simultaneously achieves the two functions of air passage conduction and static sealing.

[0069] Furthermore, at least four positioning windows 4 are provided on one side of the table body 1 for the camera below the table body 1 to take pictures and position; the positioning window 4 is a through hole that runs from the upper surface of the table body 1 through the lower surface of the table body 1. When the position of the table body 1 is offset, the camera passes through the positioning window 4 to take pictures of the position of the printed paper located on the upper surface of the table body 1, and transmits the captured data to the external main controller. The external main controller controls the table body 1 to move and correct its position.

[0070] In this embodiment, the positioning windows 4 have a defined geometric shape, such as a circle or square, and are distributed in an array at specific intervals. Their positions are precisely designed, typically located in the edge area of ​​the platen body 1, so as not to affect the effective area of ​​the printing area, while providing sufficient reference points for the camera's field of view. When the printing paper is placed on the upper surface of the platen body 1, the camera located below the platen body 1 takes an upward picture through the positioning windows 4 to acquire an image of the position of the paper edge or preset mark relative to the positioning windows 4, such as corner points or alignment lines. The image data captured by the camera contains deviation information between the actual position and the ideal position of the paper, such as offset and rotation angle.

[0071] Image data is transmitted in real time to an external main controller, such as the printer's central control system. The external main controller analyzes deviations using image recognition algorithms and calculates the necessary correction actions. The external main controller drives the moving mechanism of the printing platen 1, such as a servo motor or linear guide rail, to fine-tune the printing platen 1, ensuring that it precisely returns the paper to the preset printing coordinate system, completing automatic positioning and correction. This process can be performed automatically before printing or periodically during multi-layer printing or continuous paper feeding, ensuring that each sheet of paper is in a high-precision alignment state.

[0072] like Figure 3 and Figure 5As shown, further, a first slot 41 is provided on the top outer side of the positioning window 4, and a first cover plate 42 is installed in the first slot 41. The first cover plate 42 is made of transparent material. When the first cover plate 42 is installed in the first slot 41, the upper surface of the first cover plate 42 is at the same level as the upper surface of the platform body 1. A second slot 43 is provided on the bottom outer side of the positioning window 4, and a second cover plate 44 is installed in the second slot 43. The second cover plate 44 is made of transparent material. A receiving plate 45 is also fixedly installed on the bottom outer side of 4. A camera window 451 is opened in the middle of the receiving plate 45. The camera located below the table body 1 takes pictures of the position of the printing paper on the upper surface of the table body 1 through the camera window 451, the first cover plate 42 and the second cover plate 44. The minimum inner diameter of the camera window 451 is smaller than the minimum inner diameter of the positioning window 4. When the receiving plate 45 is fixedly connected to the lower surface of the table body 1, the second cover plate 44 is fixedly installed in the second slot 43.

[0073] In this embodiment, the transparent material can be optical glass or acrylic. After installation, the upper surface of the first cover plate is flush with the upper surface of the main body of the printing plate, forming a continuous, stepless, flat printing support surface, avoiding jamming or scratches caused by steps when the paper moves. The first cover plate 42 and the second cover plate 44 together seal both ends of the positioning window 4 to prevent external contaminants from entering the interior of the positioning window 4 and affecting the camera's image capture.

[0074] The receiving plate 45 is fixed to the lower surface of the platform by screws or clips. During installation, upward pressure is applied to the second cover plate 44, firmly pressing it into the second slot 43 to achieve mechanical limiting fixation. When the camera is located below the platform, its shooting path passes sequentially through the camera window 451, the second cover plate 44, the internal space of the positioning window 4, the first cover plate 42, and the printing paper on the upper surface of the platform body 1. The entire optical path remains unobstructed through the transparent first cover plate 42 and the second cover plate 44, while being protected by the physical structure.

[0075] During the print preparation stage, the camera captures the paper position on the upper surface of the platen body 1 through the aforementioned optical channel. The transparent first cover plate 42 and second cover plate 44 do not affect light transmission, and the image recognition system can clearly capture the paper edges or markings. The external main controller determines the positional deviation based on the image data and drives the platen body 1 to perform automatic correction. Throughout the process, the structure of the first cover plate 42, second cover plate 44, and receiving plate 45 ensures the cleanliness, stability, and sealing of the optical channel.

[0076] Furthermore, multiple threaded holes 11 are equidistantly provided on both sides of the table body 1, and the table body 1 is mounted on the printer by bolts passing through the threaded holes 11.

[0077] In this embodiment, the equally spaced threaded holes 11 ensure uniform force distribution on the platen and avoid torsional deformation caused by single-point or asymmetrical fixing; the bolt connection method has high mechanical strength and vibration resistance, and can effectively resist the vibration and impact generated when the print head reciprocates at high speed; the platen body 1 can be quickly disassembled and replaced at any time by unscrewing the bolts, which is convenient for cleaning, maintenance or replacement of platen modules with different functions.

[0078] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
