Description

Technical Field

[0001] The utility model belongs to the technical field of cardboard processing, and particularly relates to a cardboard processing hot pressing device. Background Art

[0002] Cardboard is a hard or semi-hard sheet material formed by stacking and pressing multiple layers of paper or pulp fibers. It usually has higher thickness, strength, stability and surface smoothness than ordinary paper. Cardboard can be divided into many types according to different raw materials, manufacturing processes and uses, such as corrugated cardboard (for packaging boxes), gray cardboard (for folders, picture frame backboards), white cardboard (for gift boxes, business cards and other high-end printed products), industrial cardboard (for industrial purposes such as pallets and pads), etc. Cardboard is widely used in packaging, printing, construction, decoration, handicraft production and other fields. The cardboard processing hot pressing device is a mechanical device specially designed for heating and pressing cardboard. Its main purpose is to make the glue in each layer of material inside the cardboard tightly combined by applying temperature and pressure. The existing cardboard hot pressing device is prone to glue residue after long-term use, which affects the hot pressing effect and product quality, and the cleaning work is complicated.

[0003] For example, the utility model with announcement number CN209274060U discloses a hot pressing device for cardboard processing. In this patent solution, it cannot automatically scrape and clean the glue liquid overflowing when the cardboard is hot pressed. The overflowed glue liquid may form irregular glue blocks or glue marks during the hot pressing process, affecting the flatness and appearance quality of the cardboard surface, resulting in the final product not meeting the specification requirements or reducing the appearance. Manual cleaning of the glue liquid requires regular interruption of the production process, and workers need to spend extra time on cleaning operations, reducing overall production efficiency. In addition, frequent cleaning may disrupt the production rhythm and affect the continuity of the production line. Utility Model Content

[0004] In view of this, the utility model aims to provide a cardboard processing hot pressing device to address the deficiencies of the prior art. The automatic cleaning system can ensure that each batch of cardboard is not affected by glue overflow during the hot pressing process, thereby ensuring that the product surface is flat and free of impurities, thereby improving product quality. Automated cleaning does not require manual intervention, which helps maintain a stable production rhythm and improve overall production efficiency.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a cardboard processing hot pressing device, including a workbench, a connecting plate is arranged at the upper end of the workbench, a hot pressing plate is slidably connected inside the connecting plate through a sliding column, an electric push rod 1 is arranged at the upper end of the connecting plate, the telescopic end of the electric push rod 1 is connected to the upper end of the hot pressing plate, a limiting mechanism is arranged on the left and right sides of the connecting plate, a scraping brush cleaning mechanism is arranged inside the workbench, a supporting assembly is arranged at the lower end of the workbench, the limiting mechanism includes electric push rods 2 respectively arranged on the left and right sides of the connecting plate, limiting plates are arranged on the telescopic ends of the two electric push rods 2, the scraping brush cleaning mechanism includes a scraping brush plate slidably arranged inside the workbench, two rotating seats are slidably arranged on the front side of the scraping brush plate, and the two rotating seats are The interior of the two frames is rotatably connected with a connecting frame, the middle parts of the two connecting frames are rotatably connected by a pin shaft, a frame plate is provided on the front side of the lower end of the workbench, and two rotating frames are slidingly provided inside the frame plate, the front ends of the two connecting frames are respectively rotatably connected with the adjacent rotating frames, and two screw rods are provided for internal rotation of the frame plate, and the left and right thread directions of the two screw rods are opposite, and the two rotating frames are respectively threadedly connected with adjacent screw rods, and an electric drive unit for driving the two screw rods to rotate is provided on the bottom wall of the frame plate, the electric drive unit includes a double-axis motor provided on the bottom wall of the frame plate, and the left and right side output shafts of the double-axis motor are respectively connected with the opposite inner ends of the two screw rods through couplings, a placing plate is provided on the rear side of the workbench, a collection box is placed on the upper end of the placing plate, and a handle is provided on the rear side of the collection box.

[0006] As a further improvement of the utility model, a control panel is arranged at the upper end of the workbench, and the electric push rod 1, the electric push rod 2 and the dual-axis motor are all electrically connected to the control panel.

[0007] As a further improvement of the utility model, the support assembly includes a support plate arranged at the lower end of the workbench, and a plurality of mounting holes are opened inside the support plate.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] First, by placing the cardboard to be hot-pressed on the workbench, and then controlling the electric push rod to turn on the second operation, the telescopic end drives the limit plates on both sides to move closer to each other to limit the cardboard, preventing the cardboard from moving during hot pressing.

[0010] Secondly, the control panel is used to control the opening of the hot pressing plate and the operation of the electric push rod, so that the telescopic end of the electric push rod drives the hot pressing plate to move downward to the upper end of the cardboard to achieve hot pressing of the cardboard. The glue in the cardboard will overflow onto the workbench due to the pressure. After the hot pressing is completed, the clamping plates on the electric push rod are controlled by the control panel to move away from the left and right sides of the scraper plate, and the control panel is used to control the opening of the electric push rod to move the heating plate upward away from the upper end of the cardboard, so that the hot-pressed cardboard can be taken out, and the cardboard can be hot-pressed quickly.

[0011] Thirdly, the dual-axis motor is turned on through the control panel, and the output shaft rotates to drive the lead screw to rotate, so that the rotating frames approach each other, and the connecting frame on the rotating frame rotates and shrinks with the central pin shaft, so that the two rotating seats slide inside the scraper and brush plate, driving the scraper and brush plate to move backward to scrape the glue overflowing on the workbench and the limit plate to the inside of the collection box. The glue scraped under the brush inside the collection box can be processed through the handle. The automatic cleaning system can ensure that each batch of cardboard is not affected by glue overflow during the hot pressing process, ensure that the product surface is flat and free of impurities, improve product quality, and automatic cleaning does not require manual intervention, which helps to maintain a stable production rhythm and improve overall production efficiency.

[0012] Fourthly, the mounting holes on the support plate can facilitate personnel to fix it on the ground, which can make the operation of the hot pressing device more stable. BRIEF DESCRIPTION OF THE DRAWINGS
