Description

Technical Field

[0001] This utility model relates to the field of carton sealing machine technology, specifically a folding cap structure for a carton sealing machine. Background Technology

[0002] Carton sealing machines, through their automated and intelligent design, can complete a large number of sealing tasks in a short time, significantly improving packaging efficiency. For example, fully automatic servo-controlled I-beam carton sealing machines achieve precise sealing position control through a servo control system, ensuring that each carton is uniformly sealed. This is particularly suitable for handling the challenges of order surges in e-commerce packaging. Traditional manual sealing is not only time-consuming but also prone to problems such as insecure sealing and non-standard packaging. Carton sealing machines can replace manual operation, reducing labor costs and lowering the incidence of human error. Through precise control and stable operation, carton sealing machines can ensure the standardization and sturdiness of packaging, avoiding packaging quality problems caused by human factors.

[0003] However, traditional carton sealing machines have the following drawbacks:

[0004] Traditional carton sealing machines can only fold and flap the lids of fixed cartons. If the carton is changed, the installation position of the folding and flap structure needs to be adjusted manually, which is very cumbersome and reduces the efficiency of carton folding and flap flapping. Utility Model Content

[0005] The purpose of this utility model is to provide a folding structure for a carton sealing machine, so as to solve the problem mentioned in the background art that traditional carton sealing machines can only fold the lids of fixed cartons. If the carton is changed, the installation position of the folding structure needs to be adjusted manually, which is very cumbersome and reduces the folding efficiency of the carton.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a folding cap structure for a carton sealing machine, comprising a conveyor housing, a height frame fixedly installed in the middle of the conveyor housing, lifting grooves on both sides of the inner wall of the height frame, lifting blocks slidably connected inside the two lifting grooves, a movable shell fixedly installed between the two lifting blocks, two movable blocks at the bottom of the movable shell, and folding cap assemblies fixedly installed on one side of each of the two movable blocks, each of the two folding cap assemblies comprising a length plate and a connecting seat, one side of the bottom of the length plate being fixedly connected to the top of the connecting seat, a connecting rod rotatably connected inside the connecting seat, a height plate fixedly installed at the bottom of the connecting rod, and a connecting platform fixedly installed at the bottom of the height plate.

[0007] Preferably, a first sliding groove is formed in the middle of the length plate, and a first sliding block is slidably connected inside the first sliding groove. A second sliding groove is formed in the middle of the height plate, and a second sliding block is slidably connected inside the second sliding groove. A displacement cylinder is fixedly installed on one side of the inner wall of the first sliding groove. The movable end of the displacement cylinder is fixedly connected to the side opposite to the first sliding block. Reinforcing rods are rotatably connected between the two ends of the first sliding block and the two ends of the second sliding block. When the displacement cylinder performs telescopic movement, it pushes the first sliding block from one side, and the first sliding block slides along the first sliding groove. The first sliding block drives the second sliding block to slide along the second sliding groove through the reinforcing rods. Under the push of the reinforcing rods, the connecting rod deflects along the connecting seat, adjusting the folding angle of the folding assembly, which facilitates different angle folding operations of the carton.

[0008] Preferably, one end of each of the two length plates is fixedly connected to one end of each of the two movable blocks that are directly opposite each other.

[0009] Preferably, a lifting cylinder is fixedly installed at the top of the height frame. The movable end of the lifting cylinder is fixedly connected to the middle of the top of the movable shell.
