Description

Technical Field

[0001] This invention relates to the field of screen printing machine technology, specifically to a screen printing machine that facilitates pre-flattening of paper. Background Technology

[0002] A screen printing machine is a type of printing press used for screen printing. Screen printing involves stretching silk, synthetic fiber, or metal mesh onto a frame, creating a screen printing plate using manual etched film or photochemical methods, and then using a screen printing machine to complete the printing process. A search revealed existing public technology, specifically publication number CN218928912U, which describes a screen printing machine. This technology aims to improve the way the entire printing component moves towards the product to be printed, thus reducing the overall instability of the printing press. The screen printing machine includes a worktable and a support frame mounted on the upper surface of the worktable. A screen printing plate is mounted on the support frame, and a squeegee is movable on the screen printing plate. A drive assembly for driving the squeegee to perform printing is provided on the worktable. A support platform for carrying the product to be printed is also provided on the worktable, along with a lifting assembly for moving the support platform closer to or away from the screen printing plate. This application aims to improve the overall operational stability of the printing press.

[0003] While the above solution addresses the stability of the screen printing machine during operation, it suffers from several drawbacks. The machine places the object to be printed on a support platform, but the lack of a structure to secure the object or paper on the platform allows for displacement during the upward movement, hindering accurate printing. Furthermore, the lack of a paper pre-leveling function in this upward-moving solution results in uneven paper and flawed printed patterns. Additionally, the absence of a drying function means that the paper and objects require a prolonged drying period after printing. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a screen printing machine that facilitates paper pre-flattening. This solves the problem that in the screen printing machines described in the background, the object to be printed is placed on a support platform during operation. However, since the support platform lacks a structure to secure the object or paper, displacement can easily occur during the upward movement, leading to inaccurate printing. Furthermore, the screen printing machines in the rising scheme lack a paper pre-flattening function, resulting in unevenness in the printed pattern and defects. Additionally, the screen printing machines in the aforementioned solutions lack a drying function, requiring a long drying time for the paper and objects after printing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a screen printing machine that facilitates paper pre-flattening, comprising a screen printing machine structure, wherein the screen printing machine structure is provided with a flattening and drying structure inside;

[0006] The screen printing machine structure includes a screen printing machine body with an internal placement platform, and a mounting groove is provided on one side of the placement platform to facilitate the fixed installation of flat drying structural components. Meanwhile, a hollow box is fixedly installed on one side of the inside of the screen printing machine body.

[0007] The hollow box is equipped with a spiral hollow tube with a heating rod wound inside. Both ends of the spiral hollow tube pass through the hollow box and the components in the screen printing machine body and are respectively connected to the fan and the branch pipe with an automatic control valve.

[0008] By adopting the above technical solution, the branch pipes are set up to achieve the purpose of diverting and transporting.

[0009] Preferably, the other end of the fan and the branch pipe are respectively installed and connected to one end of the corrugated connecting pipe, and the other end of the corrugated connecting pipe is respectively installed and connected to the flat drying structure components. A control heater for controlling the heating of the heating rod is fixedly installed above the hollow box.

[0010] By adopting the above technical solution, negative pressure extraction is achieved through the installation of a fan.

[0011] Preferably, the flat drying structure includes a base frame with through holes, and the base frame is fixedly installed on the placement platform. At the same time, a connecting seat is fixedly installed on the base frame. A groove is opened above the surface of the connecting seat, and a guide groove is opened through the groove. Guide sliding grooves are opened on both sides of the inner wall of the groove.

[0012] By adopting the above technical solution, the force of the drive can be adjusted by setting up a placement platform.

[0013] Preferably, a rotary motor is fixedly installed on the placement platform below the base frame, and the output end of the rotary motor extends through the through hole above the base frame. At the same time, a rotating connecting rod assembly is fixedly installed at the output end of the rotary motor. One end of the rotating connecting rod assembly is rotatably fitted with a locking pin, and the other end of the locking pin passes through the guide groove and is fixedly connected to the bottom of the bearing seat with the sliding strip.

[0014] By adopting the above technical solution, the bearing housing is designed to achieve through-rotation matching.

[0015] Preferably, the bearing housing is slidably mounted on the connecting seat via a sliding bar, and the bearing housing is provided with a rotating rod for rotation adjustment. At the same time, one end of the rotating rod is fixedly connected to a contact rod via a connecting plate. The contact rod is slidably connected to a sliding reversing groove, and the sliding reversing groove is opened inside the arched plate. Meanwhile, the arched plate is fixedly installed on one side above the connecting seat.

[0016] By adopting the above technical solution, the contact rod is designed to drive rotation adjustment.

[0017] Preferably, a connecting plate is fixedly installed at the other end of the rotating rod, and a mounting bracket is fixedly installed on one side surface of the connecting plate. A scraper plate is fixedly installed at the bottom of the mounting bracket. A cavity plate is fixedly installed above the base frame, and a vent hole is opened through the surface of the cavity plate. At the same time, a cavity tube is fixedly installed at the bottom of the cavity plate through a grid.

[0018] By adopting the above technical solution, negative pressure adsorption is achieved through the ventilation holes.

[0019] Preferably, one end of the hollow tube is connected to the other end of the corrugated connecting tube via a connecting tube, and the other end of the other corrugated connecting tube is also connected to the hollow tube via a connecting tube embedded and penetrated below one side.

[0020] By adopting the above technical solution, hot air can be transported through the hollow tube.

[0021] Preferably, the base frame is arranged in an "L" shape.

[0022] By adopting the above technical solution, the base frame is set up to achieve synchronous force-driven adjustment during installation.

[0023] Preferably, the connector has an overall "open" structure.

[0024] By adopting the above technical solution, the connection seat is set to enable the setting.

[0025] Compared with the prior art, the beneficial effects of the present invention are: this screen printing machine facilitates paper pre-flattening.

[0026] (1) This case solves the problem that the screen printing machine in the rising scheme does not have the function of pre-flattening the paper by setting the following components in the flat drying structure: rotary motor, rotating connecting rod group, locking pin, guide groove, sliding bar, bearing seat, rotating rod, connecting plate, contact rod, arch plate, sliding reversing groove, connecting plate, mounting frame and scraper plate. When the paper is placed on the cavity plate, the operator controls the rotary motor to run. When the rotary motor runs, it drives the bearing seat to slide by rotating the connecting rod group, locking pin and sliding bar. When the bearing seat slides under force, it drives the rotating rod, connecting plate, contact rod, connecting plate, mounting frame and scraper plate to move synchronously. When the scraper plate moves under force, it scrapes the paper. When the contact rod contacts the curved groove in the sliding reversing groove, the rotating rod drives the mounting frame and scraper plate to rotate under force, thereby driving the mounting frame and scraper plate to rotate 90 degrees to avoid affecting the screen printing of the paper.

[0027] (2) By using the cavity plate, ventilation holes and fan in the flat drying structure and screen printing machine structure, the problem in the above scheme is solved: the screen printing machine places the object to be printed on the carrier platform during operation, but since there is no structure to fix the object or paper on the carrier platform, the object or paper placed on the carrier platform is prone to displacement during the upward process, which makes it impossible to perform accurate printing. When the paper or material is placed on the cavity plate, the fan runs. When the fan runs, it forms a corresponding suction force on the placed paper and object through the ventilation holes, thereby adsorbing and limiting the placed paper and object.

[0028] (3) By using the following components in the screen printing machine structure and flat drying structure: hollow box, spiral cavity tube, heating rod, branch pipe, fan, corrugated connecting pipe, control heater and cavity tube, the problem that the screen printing machine in the above scheme does not have a drying function and that the paper and items after printing need to be dried for a long time is solved. When the paper needs to be dried after printing, the fan will transport the gas drawn in through the corrugated connecting pipe to the inside of the spiral cavity tube and heat it through the heating rod. After the air is heated, it will be transported to the inside of the cavity tube through another corrugated connecting pipe. The hot air entering the cavity tube heats the cavity tube and thus quickly dries the paper printed on the cavity plate. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1-13 This invention provides a technical solution: a screen printing machine that facilitates pre-flattening of paper, such as... Figure 1 , Figure 2 and Figure 3 As shown, the screen printing machine includes a screen printing machine structure 1. The screen printing machine structure 1 includes a screen printing machine body 101 with an internal placement platform 102. The placement platform 102 has an installation groove on one side to facilitate the fixed installation of the drying structure 2 components. At the same time, a hollow box 103 is fixedly installed on one side inside the screen printing machine body 101. A heating rod 105 is wound inside the hollow box 103 and a spiral cavity tube 104 is fixedly installed. Both ends of the spiral cavity tube 104 pass through the hollow box 103 and the components in the screen printing machine body 101 and are respectively installed and connected to a fan 106 and a branch pipe 107 with an automatic control valve. The screen printing machine body 101 and the placement platform 102 adopt the overall structural setting of the screen printing machine disclosed in CN218928912U. When the above-mentioned components are installed using this structure, the normal operation and control drive adjustment of the overall equipment are effectively guaranteed.

[0045] Furthermore, the other ends of the fan 106 and the branch pipe 107 are respectively installed and connected to one end of the corrugated connecting pipe 108, and the other end of the corrugated connecting pipe 108 is respectively installed and connected to the components of the flat drying structure 2. A control heater 109 for controlling the heating of the heating rod 105 is fixedly installed above the hollow box 103. The above components constitute a control heating and control air outlet structure. When the control heating and control air outlet structure constituted by the above components is used, not only is the airflow transported, but also the airflow is discharged and treated, effectively achieving the effect of flexible use of airflow.

[0046] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the screen printing machine structure 1 has a flattening and drying structure 2 inside. The flattening and drying structure 2 includes a base frame 201 with through holes. The base frame 201 is L-shaped. This L-shape not only improves the practicality of the component installation but also ensures sufficient space after the components are fixedly installed with the cavity plate 2019. Furthermore, the L-shape provides structural support and through-connectivity for the component installation. The base frame 201 is fixedly mounted on the placement table 102, and a connecting seat 202 is fixedly mounted on the base frame 201. The body shape is set in an "open" structure. The "open" structure of the above-mentioned components reflects the openness of the surface on which the above-mentioned components are installed, as well as the fixed connection of the above-mentioned components. The "open" structure of the above-mentioned components also reflects the axial symmetry of the installation of the above-mentioned components. A groove 203 is opened above the surface of the connecting seat 202, and a guide groove 204 is opened through the groove 203. At the same time, guide sliding grooves 205 are opened on both sides of the inner wall of the groove 203. There is one set of guide sliding grooves 205. The presence of one set of guide sliding grooves ensures the stable driving and sliding of the bearing seat 209.

[0047] Furthermore, the above scheme includes a rotary motor 206 fixedly mounted on the placement platform 102 below the base frame 201, with the output end of the rotary motor 206 extending through a through hole above the base frame 201. A rotating connecting rod assembly 207 is fixedly mounted at the output end of the rotary motor 206. A locking pin 208 is rotatably mounted at one end of the rotating connecting rod assembly 207, and one end of the locking pin 208 passes through a guide groove 204 and is fixedly connected to the bottom of the bearing seat 209 with the sliding bar 2010. These components constitute the driving sliding motion. During the driving sliding operation, the sliding distance of the bearing seat 209 is effectively changed. By changing the sliding driving distance of the bearing seat 209, the rotating rod 2011 is synchronously and effectively adjusted.

[0048] like Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, in a further embodiment of the above scheme, the bearing housing 209 is slidably mounted on the connecting seat 202 via the sliding bar 2010, and the bearing housing 209 is provided with a rotating rod 2011 for rotation adjustment. One end of the rotating rod 2011 is fixedly connected to the contact rod 2013 via the connecting plate 2012. The contact rod 2013 is slidably connected to the sliding reversing groove 2014, which is located inside the arched plate 2015. The arched plate 2015 is fixedly installed on the connecting seat 202. On one side above seat 202, the sliding reversing groove 2014 is a sliding reversing groove composed of horizontal straight grooves and curved grooves. When the sliding reversing groove 2014 is used, the rotation direction of the contact rod 2013 and the rotating rod 2011 is effectively changed. By changing the rotation direction of the rotating rod 2011, the scraper plate 2018 is prevented from always being above the cavity plate 2019, which would affect the normal screen printing of paper or materials.

[0049] Furthermore, in the above scheme, a connecting plate 2016 is fixedly installed at the other end of the rotating rod 2011, and a mounting bracket 2017 is fixedly installed on one side surface of the connecting plate 2016. A scraper plate 2018 is fixedly installed at the bottom of the mounting bracket 2017. A cavity plate 2019 is fixedly installed above the base frame 201, and a vent hole 2020 is opened through the surface of the cavity plate 2019. At the same time, a cavity tube 2021 is fixedly installed at the bottom of the cavity plate 2019 through a grid. One end of the cavity tube 2021 is connected to the other end of the corrugated connecting tube 108 through a connecting tube. The other end of the other corrugated connecting tube 108 is also connected to the lower side of the cavity tube 2021 through a connecting tube. The above components constitute a driving rotation structure. When the driving rotation structure constituted by the above components is used, the driving sliding rotation angle of the scraper plate 2018 is changed. By changing the driving sliding rotation angle of the scraper plate 2018, normal screen printing processing of paper and items is ensured.

[0050] In the above scheme, when the paper needs to be screen printed, the operator manually places the paper on the cavity plate 2019. When the blower 106 is running, it creates negative pressure to transport the extracted gas into the corrugated connecting pipe 108. If the gas entering the corrugated connecting pipe 108 needs to be heated, it is transported to the cavity pipe 2021 through the branch pipe 107 and another corrugated connecting pipe 108. When the gas does not need to be heated, it is directly discharged through the cavity pipe 2021. When the paper is adsorbed and limited, the drive device in the screen printing machine body 101 controls the placement table 102 to move upward. At this time, the rotary motor 206 runs synchronously and drives the bearing seat 209 to slide by rotating the connecting rod group 207, the locking pin 208 and the sliding bar 2010. When the bearing seat 209 slides under force, it drives the rotating rod 2011, the connecting plate 2012, the contact rod 2013, the connecting plate 2016 and the mounting bracket 2012. 017 and the squeegee 2018 move synchronously. When the squeegee 2018 is subjected to force, it flattens the placed paper. When the contact rod 2013 contacts the curved groove in the sliding reversing groove 2014, the rotating rod 2011 drives the mounting frame 2017 and the squeegee 2018 to rotate under force, thereby causing the mounting frame 2017 and the squeegee 2018 to rotate 90 degrees. At this time, the screen printing equipment in the screen printing machine body 101 prints on the rising paper. When the printed paper needs to be dried, the automatic control valve in the branch pipe 107 is closed, and the heater 109 and the heating rod 105 are controlled to run. The airflow entering the spiral cavity pipe 104 is heated and then transported into the cavity pipe 2021. The hot airflow entering the cavity pipe 2021 heats the cavity pipe 2021, and the heat diffused through the cavity pipe 2021 dries the printed paper.
