Description

Technical Field

[0001] This utility model relates to the field of box gluing machine technology, and in particular to a hot pressing mechanism for a fully automatic box gluing machine that prevents sticking. Background Technology

[0002] In the packaging and printing industry, the hot pressing mechanism of a fully automatic carton gluing machine is a crucial step in achieving carton forming. Its performance directly affects the forming quality and production efficiency of the carton. The anti-sticking hot pressing mechanism, through automated cleaning and precise hot pressing design, avoids problems such as mold contamination and uneven hot pressing caused by cardboard residue sticking together, reducing the frequency of manual cleaning and downtime, and ensuring production continuity. At the same time, the efficient anti-stick structure reduces the corrosion of the mold surface by glue residue, extends the mold's lifespan, and reduces maintenance costs. This is of great significance for improving the automation level of packaging production, product quality stability, and enterprise economic benefits.

[0003] Most existing carton gluing machines employ a hot pressing mechanism with upper and lower molds pressing against each other. The upper mold is driven to press down by a hydraulic or pneumatic device, and works with the lower mold to complete the hot pressing of the carton. The heating function usually relies on a built-in heating plate or heating rod, which heats the mold through conduction to melt the glue and achieve the bonding of the carton.

[0004] However, existing conventional carton gluing machines' hot pressing mechanisms struggle to automatically clean adhesive residue from the mold surface, leading to decreased production efficiency and product quality. Manual cleaning requires frequent machine downtime, and the cleaning process is prone to damaging the mold surface due to uneven force. Residual paper scraps and glue can cause defects such as indentations and weak adhesion on the carton surface during subsequent hot pressing, and may even clog heating elements, affecting heat transfer efficiency and causing uneven hot pressing temperatures. Long-term accumulation of residue can also accelerate mold corrosion, shorten mold lifespan, and increase equipment maintenance costs and downtime losses. Therefore, a fully automatic carton gluing machine hot pressing mechanism with anti-adhesion technology is proposed to solve these problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 The present invention provides an embodiment of a fully automatic anti-adhesion box gluing machine hot pressing mechanism, comprising a machine body 1, a lower mold 5 disposed inside the machine body 1, a fixed seat 6 fixedly connected to one side of the machine body 1, a slide rod 7 slidably connected inside the fixed seat 6, a fixed block 11 fixedly connected to one side of the slide rod 7, an electric push rod 8 fixedly connected to the top of the fixed seat 6, a connecting block 9 fixedly connected to the output end of the electric push rod 8, a rotating rod 10 rotatably connected inside the connecting block 9, a cleaning component disposed on one side of the rotating rod 10, and a hot pressing component disposed inside the machine body 1;

[0035] The cleaning component includes a scraper 12, one side of which is fixedly connected to the side of the rotating rod 10. The scraper 12 contacts the lower mold 5 and scrapes the surface of the lower mold 5 back and forth to effectively remove residual paper scraps and glue, ensuring the mold surface is clean and improving the quality of subsequent hot pressing. The rotating rod 10 is rotatably connected inside the fixed block 11. When the electric push rod 8 extends or retracts, it drives the connecting block 9 to move up and down, thereby driving the rotating rod 10 to swing around the fixed block 11 as a fulcrum. The hot pressing component includes a support plate 3 and an upper mold 4. The support plate 3 is set inside the machine body 1, and the upper mold 4 is set at the bottom of the support plate 3. A heating wire is set inside the upper mold 4. A hydraulic cylinder 2 is fixedly connected to the top of the machine body 1, and the output end of the hydraulic cylinder 2 is connected to the upper mold 4.

[0036] Reference Figure 1 , Figure 4 and Figure 5The lower mold 5 has a guide post 13 and a guide post 2 16 fixedly connected to its bottom. Both guide posts 13 and 2 16 are slidably connected inside the machine body 1, effectively limiting the lateral displacement of the lower mold 5 during the hot pressing process. A sliding post 14 is fixedly connected to the bottom of the lower mold 5, slidably connected inside the machine body 1. A spring 15 is fitted on the outer wall of the sliding post 14. During hot pressing, the spring 15 compresses to absorb impact force, preventing rigid collisions from damaging the mold. After hot pressing, the spring 15 releases its elastic potential energy, pushing the lower mold 5 to smoothly return to its original position, preventing the cardboard box from deforming or being damaged due to mold jamming. Spring 15 is fixedly connected to the lower mold 5 and the machine body 1 at both ends. A connecting post 17 is slidably connected to the side wall of the lower mold 5. A limiting plate 19 is fixedly connected to one side of the connecting post 17. An arc plate 20 is fixedly connected to the top of the limiting plate 19, which can closely fit the edge of the paper box and ensure that the paper box maintains accurate positioning during the hot pressing process, effectively avoiding poor adhesion caused by the paper box shifting. Spring 2 18 is sleeved on the outer wall of the connecting post 17. Spring 2 18 is fixedly connected to the lower mold 5 and the limiting plate 19 at both ends. Spring 2 18 provides flexible clamping force and automatically adjusts the position of the limiting plate 19 according to the size of the paper box.

[0037] Working principle: When using the hot pressing mechanism of this anti-adhesion fully automatic gluing box machine, firstly, the machine body 1 serves as the overall support structure. The lower mold 5 inside is used to place the paper box to be hot pressed. The hydraulic cylinder 2 is started, which can push the upper mold 4 to move down. Together with the lower mold 5, the paper box is hot pressed and formed. After the hot pressing is completed, when it is necessary to clean the surface of the lower mold 5 to prevent the paper box from sticking, the electric push rod 8 is started. It pushes the connecting block 9 to move, which drives the rotating rod 10 and the scraper 12 to move. The scraper 12 contacts the lower mold 5 and can scrape off the paper scraps and other debris stuck to the surface of the lower mold 5 to ensure the smoothness of the next hot pressing.

[0038] To ensure stability during the hot pressing process, guide pillar 13 and guide pillar 16 at the bottom of the lower mold 5 are slidably connected inside the machine body 1 to guide the mold and prevent it from shifting during hot pressing. Sliding pillar 14 is slidably connected inside the machine body 1 and spring 15 is sleeved on its outer wall. The two ends of spring 15 are connected to the lower mold 5 and the machine body 1 respectively. After hot pressing, spring 15 can assist the lower mold 5 to reset and prevent the cardboard box from getting stuck. It also provides a buffer during hot pressing. In addition, the connecting pillar 17 slidably connected to the side wall of the lower mold 5 has an arc-shaped plate 20 on the top of the limiting plate 19 on one side to limit the placed cardboard box. The two ends of spring 18 on the outer wall of the connecting pillar 17 are connected to the lower mold 5 and the limiting plate 19. It can adapt to the position of the cardboard box through elasticity during the placement and hot pressing process, help fix the cardboard box, and ensure accurate hot pressing position.
