Description

Technical Field

[0001] This utility model relates to the field of automatic pressing and conveying devices, specifically an automatic pressing and conveying device for green paper printing. Background Technology

[0002] Green printing refers to the use of environmentally friendly materials and technologies in the printing process to reduce pollution, conserve resources, and achieve sustainable development of the printing industry. The development of this technology mainly focuses on solving the environmental problems existing in traditional printing processes, such as the use of harmful solvents, high energy consumption, and large amounts of waste emissions. Moreover, the automatic pressing and conveying of paper is very important in the printing process.

[0003] In existing printing equipment, the paper moves with the conveyor, and the paper needs to be positioned during the paper cutting process. The limiting plate is used to firmly fix the paper on the conveyor belt for the cutting component to cut. The existing fixed limiting device is mainly closed manually, which requires human intervention to sort the conveyed paper.

[0004] The existing limit plate requires manual adjustment of the fixed limit device before the paper can be fixed on the conveyor belt. Manually operating the fixed limit device will bring great inconvenience to the printing workers and easily cause damage to the paper. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an automatic pressing and conveying device for green paper printing, so as to solve the technical problem that it is inconvenient for fixed limit devices to automatically clamp paper.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic pressing and conveying device for green paper printing, comprising an operating platform, two sets of rotating shafts installed inside the operating platform, a conveying assembly between the operating platform, a conveyor belt fitted on the outer wall of the two sets of rotating shafts, clamping assemblies on both sides of the conveyor belt, the clamping assemblies including fixed plates fixed to both sides of the conveyor belt, a rotating inner rod installed on one side of the fixed plates, a clamping plate fitted on the outer wall of the rotating inner rod, and a torsion spring fitted on the outer wall of the rotating inner rod, a fixing hole opened at the top of the fixed plate, a guide groove fixed at the top of the operating platform, a limit plate opened on one side of the guide groove, and a clamping assembly provided at the bottom of the guide groove, a guide groove fixedly installed on one side of the operating platform, a perforated protrusion provided on one side of the guide groove, and a roller provided at the bottom of the guide groove.

[0007] By adopting the above technical solution, the problem of inconvenience in automatically clamping paper with a fixed limiting device is solved. With the set guide groove and clamping plate, when the conveyor belt rotates, the guide groove constrains the clamping plate to rotate horizontally along the curved surface, thereby clamping the paper. A movable curved edge pressure plate is set on one side of the guide groove. After the clamping plate passes through the curved surface, it will contact the curved edge pressure plate. The curved edge pressure plate will further press one end of the clamping plate downward by its own weight, preventing the torsion spring from causing the clamping plate to warp, ensuring the clamping plate's ability to hold the paper, preventing the clamping plate from loosening and causing paper displacement. After the clamping plate passes through the guide groove, the torsion spring will bounce the clamping plate up and reset it. By rotating the conveyor belt, it will rotate to the initial position, thus allowing for repeated use.

[0008] The present invention is further configured such that the operating platform is provided with multiple sets of rollers inside, and the rollers are located at the top of the inner wall of the rotating roller.

[0009] By adopting the above technical solution, multiple sets of rollers set at the top of the inner wall of the rotating roller support the operation of the conveyor belt and improve the load-bearing capacity of the conveyor belt.

[0010] The present invention is further configured such that the diameters at both ends of the rotating roller and the shaft are smaller than those of the conveyor belt.

[0011] By adopting the above technical solution, the fixed plate fixed on one side of the conveyor belt can rotate cyclically, avoiding collisions with other components.

[0012] The present invention is further configured such that a horizontal groove is provided at the bottom of the guide groove, and a roller is movably installed at the top of the inner wall of the horizontal groove.

[0013] By adopting the above technical solution, direct contact between the guide groove and the clamping plate is avoided. The rollers are movably connected to the clamping plate, which reduces the friction between the two and increases the clamping plate's mobility at the bottom of the guide groove.

[0014] The present invention is further configured such that a perforated protrusion is fixed on one side of the guide groove, and a fixing bolt is movably installed inside the perforated protrusion, and a curved pressure plate is movably installed at the end of the fixing bolt.

[0015] By adopting the above technical solution, the curved edge pressure plate is movably installed on one side of the guide groove. When the clamping plate passes through the top of the guide groove, the curved edge pressure plate automatically presses the end of the clamping plate to prevent the torsion spring from causing the clamping plate to warp.

[0016] The present invention is further configured such that the end of the curved edge pressure plate is inclined.

[0017] By adopting the above technical solution, when the clamping plate comes into contact with the curved edge pressure plate, it can slide into the bottom of the curved edge pressure plate better through the inclined surface at the end of the curved edge pressure plate, thereby lifting the curved edge pressure plate.

[0018] The present invention is further configured such that one side of the limiting plate is a torsional curved surface, and a baffle is provided on the top of the fixing plate.

[0019] By adopting the above technical solution, the curved surface of the limiting plate facilitates the automatic rotation of the clamping plate, enabling it to automatically perform the clamping process and clamp the paper, avoiding manual intervention. The top of the fixing plate is equipped with a baffle to prevent the torsion spring from excessively pushing the clamping plate, thus preventing the clamping plate from aligning with the torsional curved surface of the limiting plate.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention solves the problem of inconvenient automatic paper clamping in fixed limiting devices by setting up guide grooves, fixing plates, curved edge pressure plates, torsion springs, and clamping plates. Through the guide grooves and clamping plates, when the conveyor belt rotates, the guide grooves constrain the clamping plates to rotate horizontally along the curved surface, thereby clamping the paper. A movable curved edge pressure plate is provided on one side of the guide groove. After the clamping plate passes the curved surface, it comes into contact with the curved edge pressure plate. The curved edge pressure plate, through its own weight, further presses one end of the clamping plate downwards, preventing the torsion spring from causing the clamping plate to warp, ensuring the clamping plate's ability to hold the paper, preventing the clamping plate from loosening and causing paper displacement. After the clamping plate passes through the guide groove, the torsion spring will spring the clamping plate back up, allowing it to reset. The rotation of the conveyor belt then returns it to its initial position, thus enabling cyclical use. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] An automatic pressing and conveying device for green paper printing, such as Figure 1 - Figure 6 As shown, the system includes an operating platform 1, with two sets of rotating rollers 2 installed inside the operating platform 1. A conveyor assembly is set between the operating platform 1. A conveyor belt 3 is fitted on the outer wall of the two sets of rotating rollers 2. Clamping assemblies are set on both sides of the conveyor belt 3. The clamping assemblies include fixed plates 7 fixed on both sides of the conveyor belt 3. A rotating inner rod 14 is installed on one side of the fixed plate 7. A clamping plate 9 is fitted on the outer wall of the rotating inner rod 14. A torsion spring 8 is fitted on the outer wall of the rotating inner rod 14. A guide groove 51 is fixed on the top of the operating platform 1. A limit plate 5 is opened on one side of the guide groove 51. A clamping assembly is set at the bottom of the guide groove 51. The guide groove 51 is fixedly installed on one side of the operating platform 1. A perforated protrusion 11 is set on one side of the guide groove 51. A roller 12 is set at the bottom of the guide groove 51.

[0032] Please see Figure 3 The operating platform 1 is equipped with multiple sets of rollers 4, and the rollers 4 are located at the top of the inner wall of the roller 2. The multiple sets of rollers 4 located at the top of the inner wall of the roller 2 support the operation of the conveyor belt 3 and improve the load-bearing capacity of the conveyor belt 3.

[0033] Please see Figure 3 The diameters at both ends of the roller 2 and the roller 4 are smaller than those of the conveyor belt 3, which facilitates the cyclic rotation of the fixed plate 7 fixed on one side of the conveyor belt 3 and avoids collisions with other components.

[0034] Please see Figure 4 and Figure 5 The bottom of the guide groove 51 is provided with a horizontal groove 52, and a roller 12 is movably installed on the top of the inner wall of the horizontal groove 52. This avoids direct contact between the guide groove 51 and the clamping plate 9. The roller 12 is movably connected to the clamping plate 9, which reduces the friction between the two and increases the mobility of the clamping plate 9 at the bottom of the guide groove 51.

[0035] Please see Figure 4 and Figure 5 A perforated protrusion 11 is fixed on one side of the guide groove 51, and a fixing bolt 10 is movably installed inside the perforated protrusion 11. A curved edge pressure plate 6 is movably installed at the end of the fixing bolt 10, so that the curved edge pressure plate 6 is movably installed on one side of the guide groove 51. When the clamping plate 9 passes through the top of the guide groove 51, the curved edge pressure plate 6 automatically presses the end of the clamping plate 9 to prevent the torsion spring 8 from causing the clamping plate 9 to warp.

[0036] Please refer to 5. The end of the curved edge pressure plate 6 is inclined. When the clamping plate 9 contacts the curved edge pressure plate 6, it can slide into the bottom of the curved edge pressure plate 6 better through the inclined surface of the end of the curved edge pressure plate 6, thereby lifting the curved edge pressure plate 6.

[0037] Please see 4 and Figure 6 The limiting plate 5 has a torsional curved surface on one side, and the top of the fixing plate 7 is equipped with a baffle. The torsional curved surface of the limiting plate 5 facilitates the rotation of the clamping plate 9, enabling it to automatically perform the clamping process and clamp the paper, avoiding manual intervention. The baffle at the top of the fixing plate 7 prevents the torsion spring 8 from excessively pushing the clamping plate 9, thus preventing the clamping plate 9 from aligning with the torsional curved surface of the limiting plate 5.

[0038] The working principle of this utility model is as follows: After the paper is placed on the conveyor belt 3, it is driven forward by the conveyor belt 3. The clamping component on the side of the conveyor belt 3 is in a spring-up state. As the conveyor belt 3 moves, the clamping plate 9 in the clamping component comes into contact with the torsional surface of the limiting plate 5. The clamping plate 9 rotates along the torsional surface and tends to be horizontal. After passing the torsional surface, the clamping plate 9 is in close contact with the bottom of the guide groove 51. The bottom of the guide groove 51 is provided with a roller 12, which makes it contact the surface of the clamping plate 9 to reduce friction. A curved edge pressure plate 6 is movably installed on one side of the guide groove 51. After the clamping plate 9 passes the curved surface, it will come into contact with the curved edge pressure plate 6. The curved edge pressure plate 6 will further press one end of the clamping plate 9 downward by its own weight to prevent the torsion spring 8 from causing the clamping plate 9 to warp.

[0039] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
