Abstract
Description
Technical Field
[0001] This utility model belongs to the field of corrugated paper processing technology, and in particular relates to a high-frequency hot-pressing sealing device for corrugated paper joints. Background Technology
[0002] In the modern commodity circulation system, corrugated paper packaging plays an indispensable role. With the prosperity of global trade and the rapid rise of the e-commerce industry, the usage of corrugated paper packaging has grown exponentially. Due to its low cost, recyclability, and good cushioning and protection performance, it is widely used in the transportation and storage of various products. Ensuring the airtightness of corrugated paper packaging is the key to ensuring the safety and integrity of the contents. High-frequency hot-pressing lamination technology, as an important means of achieving sealing of corrugated paper seams, has been widely used in packaging production lines because it can quickly and effectively fuse the materials at the corrugated paper seams.
[0003] However, the existing high-frequency hot-press bonding corrugated paper joint sealing device has a large impact force on the hydraulic cylinder during use, which can easily damage the sealing mold, thereby reducing the sealing speed and reducing the efficiency of corrugated paper production, thus affecting the corrugated paper processing efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a high-frequency hot-press bonding corrugated paper joint sealing device. By setting a downward pressure buffer mechanism, it solves the problem that the hydraulic cylinder has a large impact force during the use of the existing high-frequency hot-press bonding corrugated paper joint sealing device, which can easily damage the sealing mold, thereby reducing the sealing speed, reducing the efficiency of corrugated paper production, and affecting the corrugated paper processing efficiency.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a high-frequency hot-press bonding corrugated paper joint sealing device, including a base, on which a demolding mechanism and a pressing buffer mechanism are provided;
[0007] The demolding mechanism includes a mold fixedly connected to the top of the base. A limit groove is provided on the base. The pressing and buffering mechanism includes a pressing component and two buffer components. The pressing component includes a bracket fixedly connected to the top of the base. A hydraulic cylinder is fixedly connected to the bottom of the bracket. A fixed plate is fixedly connected to the bottom of the hydraulic cylinder. A pressing mold is fixedly connected to the bottom of the fixed plate. The buffer component includes two hinge blocks fixedly connected to the bottom of the fixed plate. A hinge rod is hinged to each of the two hinge blocks.
[0008] Furthermore, the inner wall of the limiting groove is slidably connected to a second mold, the first mold and the second mold are adapted to each other, and the bottom of the base is fixedly connected to two rectangular supports.
[0009] Furthermore, a threaded rod is rotatably connected between the two rectangular supports. The threaded rod passes through the second mold, and the second mold is threadedly connected to the threaded rod. The front side of the threaded rod passes through the rectangular support located on the front side and extends outward.
[0010] Furthermore, a motor bracket is fixedly connected to the front side of the base, and a motor is fixedly connected to the outer wall of the motor bracket. The output shaft of the motor is fixedly connected to a threaded rod via a coupling.
[0011] Furthermore, a buffer plate is provided at the bottom of the fixed plate, and two trapezoidal grooves are provided at the top of the buffer plate. A slider is slidably connected to the inner wall of each of the two trapezoidal grooves, and the slider is respectively hinged to two hinge rods.
[0012] Furthermore, each of the two trapezoidal grooves is fixedly connected with a sliding rod, which passes through the two sliders respectively, and the two sliding rods are slidably connected to the two sliders respectively.
[0013] Furthermore, springs are fitted on the outer walls of both slide rods. The sides of the two springs that are close to each other are fixedly connected to the two sliders, and the sides of the two springs that are far apart from each other are fixedly connected to the inner walls of the two trapezoidal slides.
[0014] This utility model has the following beneficial effects:
[0015] 1. By setting up a demolding mechanism, the motor is started to drive the threaded rod to rotate clockwise. At this time, the second mold slides in the limiting groove and moves closer to the first mold. The protrusion of the second mold is inserted into the groove on the first mold, thus splicing the molds. After splicing, the motor is stopped, and the heat-treated corrugated paper is placed into the second mold and the first mold for pressing and sealing. After the treatment is completed, the motor is started to drive the threaded rod to rotate counterclockwise. Through the opposite movement process, the second mold moves away from the first mold, making it easier to remove the sealed corrugated paper. This allows for quick removal of the sealed corrugated paper, effectively shortening the processing cycle of a single product, speeding up the production pace, and improving overall production efficiency.
[0016] 2. By setting up a downward pressure buffer mechanism, after the corrugated paper is placed into the mold, the hydraulic cylinder is activated to drive the downward pressure mold on the fixed plate to seal the corrugated paper. When the fixed plate moves downward, it drives the two buffer components to move. At this time, the two hinge blocks drive the buffer plates on the two sliders to move through the two hinge rods and contact the top of the base. Under the action of downward pressure, the buffer plates drive the two hinge rods to move through the two sliders. The two hinge rods rotate through the two hinge blocks as fulcrums and move away from each other. At this time, the angle between the two hinge rods increases, thereby driving the two sliders to slide on the two trapezoidal slides and the two slide rods and move away from each other. At this time, the two sliders compress the two springs to generate deformation and elastic force. After the corrugated paper is sealed, the hydraulic cylinder drives the downward pressure mold to rise through the fixed plate. At this time, under the action of the elastic force of several springs, the buffer plates are reset, avoiding rigid impact directly acting on the equipment base and internal structure, greatly reducing the risk of critical components being damaged by impact, and significantly extending the overall service life of the equipment.

[0028] The downward pressure buffer mechanism 3 includes a downward pressure assembly 31 and two buffer assemblies 32. The downward pressure assembly 31 includes a bracket 311 fixedly connected to the top of the base 1. A hydraulic cylinder 312 is fixedly connected to the bottom of the bracket 311. A fixed plate 313 is fixedly connected to the bottom of the hydraulic cylinder 312. A downward pressure mold 314 is fixedly connected to the bottom of the fixed plate 313.

[0029] A specific application of this embodiment is as follows: In use, the motor 217 is started to drive the threaded rod 215 to rotate clockwise. At this time, the second mold 213 slides within the limiting groove 212 and moves closer to the first mold 211. The protrusion of the second mold 213 then inserts into the groove on the first mold 211, thus assembling the molds. After assembly, the motor 217 is stopped, and the heat-treated corrugated paper is placed into the second mold 213 and the first mold 211 for pressing and sealing. After processing, the motor 217 is started to drive the threaded rod 215 to rotate counterclockwise. Through the opposite movement process, the second mold 213 moves away from the first mold 211, facilitating the removal of the sealed corrugated paper. After the corrugated paper is placed in the mold, the hydraulic cylinder 312 is started to drive the pressing mold 314 on the fixed plate 313 to seal the corrugated paper. When the fixed plate 313 moves downwards, it... When the two buffer components 32 move, the two hinge blocks 321 drive the buffer plates 323 on the two sliders 325 to move through the two hinge rods 322 and contact the top of the base 1. Under the action of the downward pressure, the two sliders 325 drive the two hinge rods 322 to move through the buffer plates 323. The two hinge rods 322 rotate through the two hinge blocks 321 as fulcrums and move away from each other. At this time, the angle between the two hinge rods 322 increases, thereby driving the two sliders 325 to slide on the two trapezoidal slide grooves 324 and the two slide rods 326 respectively and move away from each other. At this time, the two sliders 325 squeeze the two springs 327 to generate deformation and elastic force. After the corrugated paper is sealed, the hydraulic cylinder 312 drives the lower pressing mold 314 to rise through the fixed plate 313. At this time, under the action of the elastic force of several springs 327, the buffer plate 323 is reset.
