Description

Technical Field

[0001] This application relates to the field of adsorption, and more particularly to an adsorption device for printing paper. Background Technology

[0002] Currently, printing paper is a crucial tool in daily life, and the positioning accuracy of the paper directly affects the printing quality.

[0003] In the field of paper printing, traditional adsorption devices mostly adopt a fixed negative pressure adsorption structure. Their adsorption pores are unevenly distributed and lack a flexible and adjustable positioning mechanism, causing thin or large-sized paper to easily shift or wrinkle during high-speed printing. Furthermore, existing devices struggle to quickly adapt to different printing materials, resulting in cumbersome adjustment processes and low production efficiency.

[0004] Regarding the aforementioned technologies, the applicant believes that they suffer from poor paper positioning accuracy. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides a paper adsorption device for printing.

[0006] This application provides a paper adsorption device for printing, which adopts the following technical solution:

[0007] A paper adsorption device for printing includes a rigid adsorption platform, a negative pressure mechanism, a manual adjustment mechanism, a support mechanism, and a fan. The negative pressure mechanism is mounted on the support mechanism and is fixedly connected to it. The manual adjustment mechanism is mounted on the upper side of the rigid adsorption platform and is fixedly installed to it. The negative pressure mechanism is mounted on the lower side of the rigid adsorption platform and is fixedly installed to it. The fan is mounted on one side of the negative pressure mechanism and is detachably connected to it.

[0008] By adopting the above technical solution: the rigid adsorption platform is fixed on the upper side of the negative pressure mechanism, and the fan is detachably connected to the negative pressure mechanism. During the printing process, the fan starts to work and affects the adsorption capacity of the rigid adsorption platform through the negative pressure mechanism. The support structure is installed on the lower side of the negative pressure mechanism and is fixedly connected to the negative pressure mechanism. The support structure maintains the stability of the negative pressure mechanism and the rigid adsorption platform, so that the rigid adsorption platform and the negative pressure mechanism can maintain a good working state when working. The manual adjustment mechanism can adjust the paper restriction position according to different paper sizes, making the adsorption work more efficient.

[0009] Preferably, the working surface of the rigid adsorption platform is processed to have uniformly distributed through-holes, which are arranged in a matrix.

[0010] Preferably, the negative pressure mechanism includes a cavity, a guide plate, and a through hole. The cavity is fixed to the bottom of the rigid adsorption platform, the guide plate is installed inside the cavity and is fixedly connected to the cavity, and the through hole is located at the corresponding position below the through adsorption hole, and the diameter of the through hole is slightly larger than the diameter of the through adsorption hole.

[0011] By adopting the above technical solution: the rigid adsorption platform has uniformly distributed through-holes on its working surface, and the negative pressure mechanism also has through holes, with their positions corresponding one-to-one. This allows the airflow from the fan to pass through the cavity of the negative pressure mechanism, transmitting the negative pressure state to the working surface of the rigid adsorption platform, thus allowing the paper to be better adsorbed onto the rigid adsorption platform. Furthermore, the baffle plate inside the cavity makes the airflow through the cavity more uniform, ensuring that the negative pressure state is evenly distributed within the cavity, protecting the paper from damage due to excessive pressure difference.

[0012] Preferably, the manual adjustment mechanism includes an I-beam slide rail and a slidable baffle. The I-beam slide rail is installed on both sides of the rigid adsorption platform and is fixedly connected to the rigid adsorption platform. The slidable baffle is slidably connected to the I-beam slide rail.

[0013] By adopting the above technical solution: during the paper printing process, there will be various sizes of paper. The sliding baffle in the manual adjustment mechanism can move along the rigid adsorption platform on the I-beam slide rail to change the limiting position of the paper, so that the paper adsorption and limiting work can be adjusted according to the required content.

[0014] Preferably, the support mechanism includes threaded columns at four corners, adjusting nuts, and rubber pads. The threaded columns are installed at the bottom of the negative pressure mechanism, the adjusting nuts are welded to the negative pressure mechanism, the adjusting nuts are installed on the threaded columns, and the adjusting nuts and threaded columns form a threaded pair. The rubber pads are fitted onto the ends of the threaded columns by interference fit.

[0015] By adopting the above technical solution: the adjusting nut is fixedly installed at the bottom of the four corners of the negative pressure mechanism, and the adjusting nut and the threaded column form a threaded pair. During the printing process, the working position height of the rigid adsorption platform can be changed by turning the adjusting nut and the threaded column, so that the printed paper can fall onto the rigid adsorption platform better. In addition, the rubber pad is fitted at the end of the threaded column through interference fit, which also makes the whole device more stable and reduces the working fluctuation of the device.

[0016] Preferably, the air outlet of the fan is provided with a corrugated pipe, and the negative pressure mechanism is also provided with a corrugated pipe on the connection side, with the two ends of the corrugated pipes connected by flanges.

[0017] By adopting the above technical solution: both the fan and the negative pressure mechanism extend corrugated pipes and are connected by flanges. When the fan is working, there will inevitably be some movement. Practical corrugated pipe connection can reduce the impact of the fan on the negative pressure mechanism. The flange connection can make the corrugated pipes of the two tightly connected, avoiding the leakage of airflow from the fan and the waste of resources.

[0018] Preferably, it also includes a baffle shifting mechanism, which is installed on one side of the rigid adsorption platform and the negative pressure mechanism, with one end of the baffle shifting mechanism fixed to the negative pressure mechanism.

[0019] Preferably, the baffle shifting mechanism includes wooden blocks and springs. Two wooden blocks are connected by the springs. Two baffles are provided at the end of the rigid adsorption platform. The rigid adsorption platform is rotatably connected to the baffles. The baffles are attached to the baffle shifting mechanism to keep it in a compressed state. The baffles are also located below the manual adjustment mechanism.

[0020] By adopting the above technical solution: after the paper is printed, the sliding baffle is moved to the upper side of the baffle shifting mechanism. The two baffles rotate, causing the baffle shifting mechanism to move. The upper wooden block moves upward under the action of the spring, lifting the sliding baffle to move upward along the vertical slide rail of the I-shaped slide rail, leaving a gap between the rigid adsorption platform and the sliding baffle, which facilitates the removal of the printed paper.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The rigid adsorption platform is fixed on the upper side of the negative pressure mechanism. The fan and the negative pressure mechanism are detachably connected. During the printing process, the fan starts to work and affects the adsorption capacity of the rigid adsorption platform through the negative pressure mechanism. The support structure is installed on the lower side of the negative pressure mechanism and is fixedly connected to the negative pressure mechanism. The support structure maintains the stability of the negative pressure mechanism and the rigid adsorption platform, so that the rigid adsorption platform and the negative pressure mechanism can maintain a good working condition. The manual adjustment mechanism can adjust the paper restriction position according to different paper sizes, making the adsorption work more efficient.

[0023] 2. The rigid adsorption platform has uniformly distributed through-holes on its working surface, and the negative pressure mechanism also has through holes. The positions of the two are one-to-one. This allows the airflow from the fan to pass through the cavity of the negative pressure mechanism, so that the negative pressure state is transmitted to the working surface of the rigid adsorption platform, allowing the paper to be better adsorbed on the rigid adsorption platform. In addition, the baffle plate in the cavity makes the airflow through the cavity more uniform, so that the negative pressure state is evenly present in the cavity, protecting the paper from damage due to excessive pressure difference.

[0027] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0028] This application discloses a paper adsorption device for printing. (Refer to...) Figure 1-2 The system includes a rigid adsorption platform 1, a negative pressure mechanism 2, a manual adjustment mechanism 3, a support mechanism 4, and a fan 5. The working surface of the rigid adsorption platform 1 is machined with evenly distributed through-holes 11 arranged in a matrix. The negative pressure mechanism 2 is installed on the lower side of the rigid adsorption platform 1 and is fixedly installed to it. The negative pressure mechanism 2 includes a cavity 21, a guide plate 22, and a through hole 23. The cavity 21 is fixed to the bottom of the rigid adsorption platform 1, and the guide plate 22 is installed inside the cavity 21 and fixedly connected to it. The through hole 23 is located at a corresponding position below the through-holes 11, and its diameter is slightly larger than that of the through-holes 11. The negative pressure mechanism 2 is installed on the support mechanism 4 and is fixedly connected to it. The support mechanism 4 includes four corners... The system includes a threaded column 41, an adjusting nut 42, and a rubber pad 43. The threaded column 41 is installed at the four corners of the bottom of the cavity 21 in the negative pressure mechanism 2. The adjusting nut 42 is welded to the cavity 21 in the negative pressure mechanism 2 and is installed on the threaded column 41, forming a threaded pair. The rubber pad 43 is fitted onto the end of the threaded column 41 by an interference fit. The manual adjustment mechanism 3 is installed on the upper side of the rigid adsorption platform 1 and is fixedly installed with the rigid adsorption platform 1. The manual adjustment mechanism 3 includes an I-beam slide rail 31 and a sliding baffle 32. The I-beam slide rail 31 is installed on both sides of the rigid adsorption platform 1 and is fixedly connected to the rigid adsorption platform 1. The sliding baffle 32 is slidably connected to the I-beam slide rail 31, and the bottom of the sliding baffle 32 slides in contact with the rigid adsorption platform 1.

[0029] A baffle shifting mechanism 6 is installed on one side of the rigid adsorption platform 1 and the negative pressure mechanism 2. One end of a wooden block 61 in the baffle shifting mechanism 6 is fixed to one side of the cavity of the negative pressure mechanism 2. The two wooden blocks 61 are connected by a spring 62. Two baffles 12 are provided at the end of the rigid adsorption platform 1. The rigid adsorption platform 1 is rotatably connected to the baffles 12. The baffles 12 are attached to the baffle shifting mechanism 6 to keep them in a compressed state. The baffles 12 are also located below the manual adjustment mechanism 3. When the baffles 12 are removed, the unfixed wooden block 61 is made to fit against the bottom of the sliding baffle 32 by the action of the spring 62, and pushes the sliding baffle 32 to move along the vertical slide rail of the I-beam slide rail 31. The fan 5 is installed on one side of the negative pressure mechanism 2. The fan 5 is detachably connected to the cavity 21 of the negative pressure mechanism 2. The air outlet of the fan 5 is provided with a corrugated pipe 51. The negative pressure mechanism 2 is also provided with a corrugated pipe 51 on the connecting side of the cavity 21. The two ends of the corrugated pipe 51 are connected by flanges.

[0030] The working principle of the paper adsorption device for printing according to this application is as follows: the fan 5 provides airflow through the corrugated pipe 51 into the cavity 21 of the negative pressure mechanism 2. The guide plate 22 is evenly distributed in the cavity 21. The airflow is then evenly scraped across the cavity 21 by the guide plate 22 and scraped out from the opening on the other side of the cavity. The airflow passes through the through hole 23 and the through adsorption hole 11 on the rigid adsorption platform 1, so that a pressure difference is formed between the cavity 21 and the working surface of the rigid adsorption platform 1. The printed paper is adsorbed on the rigid adsorption platform 1 by this pressure difference. On the working surface of the attached platform 1, the position of the paper is adjusted by changing the position of the sliding baffle 32 in the manual adjustment mechanism 3 on the I-beam slide rail 31. After the paper is printed, the sliding baffle 32 is moved to the baffle shifting mechanism 6. The unfixed wooden block 61 is made to fit against the bottom of the sliding baffle 32 by the action of the spring 62, and lifts the sliding baffle 32 to move along the vertical slide rail of the I-beam slide rail 31, raising the sliding baffle 32 to facilitate the removal of the printed paper.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the structure, shape, or principle of this application. All such changes should be covered within the protection scope of this application.
