[0001] This utility model relates to the field of automated production line technology, and in particular to a packaging box capping device. Background Technology

[0002] Packaging boxes are an important bridge connecting brands and consumers. Their core function is to protect products. Through reasonable material selection and structural design, they can effectively isolate external impacts, moisture, pollution and other factors, ensuring that products remain intact throughout the entire process from transportation and storage to sales. At the same time, the appearance design of packaging boxes bears the important responsibility of brand expression, helping consumers to quickly identify and develop a positive impression among many products.

[0003] The packaging process begins with the preparation of materials and equipment, which is fundamental to ensuring packaging efficiency and quality. Workers first sort out matching boxes, cushioning materials, and sealing supplies based on product characteristics and packaging requirements. Simultaneously, they check the operating status of the packaging equipment to ensure all components are functioning properly. However, during the packaging process, it is often necessary to cap the boxes to prevent defective products. With technological advancements, box capping devices typically consist of a conveying mechanism, positioning components, a capping actuator, and a control system. The cap is pressed down at a set pressure and speed to ensure a perfect fit between the cap and the box. Some devices also include a cushioning structure to prevent excessive pressure from damaging the box. However, stopping this type of packaging equipment requires manual intervention, and the box tongue is prone to deformation and damage during the capping process. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a packaging box sealing device, which aims to improve the problems in the prior art where manual intervention is required when the packaging equipment stops, and the box tongue is prone to deformation and damage during the sealing process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a packaging box pressing device, including a support plate, a pressing mechanism on the front side of the support plate, the pressing mechanism being used to press the packaging box, and a blocking mechanism on the right side of the support plate for preventing the packaging box from moving. The capping mechanism includes a fixed plate, the rear side of which is fixedly connected to the front side of a support plate. A cylinder is provided on the top of the fixed plate, and a push rod is connected to the output end of the cylinder. A connecting plate is fixedly connected to the bottom of the push rod.

A pushing assembly is provided on the rear side of the capping plate, and multiple buffer assemblies are provided on the top of the fixed plate.

[0006] As a further description of the above technical solution: The blocking mechanism includes a driving component 1, the bottom of which is fixedly connected to the front right end of the support plate. The output end of the driving component 1 is connected to a rotating rod 1. A fixing plate 2 is slidably connected to the outer wall of the rotating rod 1. The rear side of the fixing plate 2 is fixedly connected to the front side of the support plate. A rotating rod 2 is fixedly connected to the top of the rotating rod 1. A stop block is fixedly connected to the outer wall of the rotating rod 2. An anti-collision component is provided on the left side of the stop block.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the cylinder pushes downward, causing the push rod to drive the connecting plate and connecting sleeve to move downward. At this time, the cover plate will also move downward, and then the cover rod will move along the packaging box from top to bottom until it reaches the bottom. At this time, the packaging box is pressed tightly. At the same time, there are two springs at the front and back of the connecting plate to buffer and dampen the vibration of the connecting plate, which can reduce the cost and maintenance difficulty of the tongue pressing equipment, while avoiding deformation and damage of the box tongue during the pressing process. 2.

[0020] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 A drive component 4 is fixedly connected to the rear side of the support plate 1. The output end of the drive component 4 is connected to a conveyor belt 7 for conveying the packaging box. A sensor 5 for detecting the position of the packaging box is fixedly connected to the rear side of the support plate 1. A base 8 is fixedly connected to the bottom of the support plate 1. A support column 6 is fixedly connected to the top left side of the fixed plate 201. The other end of the support column 6 is fixedly connected to the cylinder 202. Specifically, a second driving component 4 is fixedly connected to the rear side of the support plate 1. The second driving component 4 provides power for the operation of the conveyor belt 7. The output end of the second driving component 4 is connected to the conveyor belt 7 for conveying the packaging box.

[0021] Working principle: First, the drive component 4 drives the conveyor belt 7 to transport the package that needs to be pressed. When it moves to the appropriate position, the sensor 5 detects the package. At this time, the cylinder 202 is activated and pushes downward, causing the push rod 203 to move the connecting plate 204 and the connecting sleeve 205 downward. At this time, the pressure plate 206 also moves downward. Meanwhile, the pressure rod 2073 is pressed tightly against the package under the elastic force of the connecting rod 2072 and the spring 2071. The pressure rod 2073 will then move from top to bottom along the package until it reaches the bottom, at which point the package is pressed. At the same time, there are springs 2082 at the front and back of the connecting plate 204 to buffer and dampen the vibration of the connecting plate 204, which can reduce the cost and maintenance difficulty of the tongue pressing equipment and avoid deformation and damage of the box tongue during the pressing process. When the drive unit 301 is activated, it will drive the rotating rods 302 and 304 to rotate. The rotating rod 304 will then rotate the stop block 305 to the front. When the packaging box hits the anti-collision pad 3063, the anti-collision pad 3063 will push the spring 3062 backward, causing the spring 3062 to compress and cushion the packaging box to prevent impact. At the same time, the anti-collision pad 3063 will drive the limit rod 3061 to slide inward into the stop block 305. After the packaging box is compacted, the drive unit 301 will restart. The drive unit 301 will then rotate the stop block 305 to the other side, allowing the packaging to continue moving into the next process. This achieves the function of blocking the packaging in a designated position, facilitating subsequent capping operations, and preventing the packaging from being damaged by impact.
