Description

Technical Field

[0001] This utility model relates to filling technology, specifically a filling tube sealing device. Background Technology

[0002] A filling production line is a route that connects raw materials to packaging equipment, encompassing processing, conveying, assembly, and inspection. This line offers significant flexibility, adapting to the needs of multi-variety production. The application of filling production lines enables high-volume production in food, pharmaceutical, and daily chemical companies, helping them achieve high-speed manufacturing. Throughout the filling process, containers are transported on the production line, undergoing operations such as container arrangement, paste filling, and container sealing.

[0003] Current filling tube sealing is mainly achieved through tail sealing. The tail sealing device for filling tubes includes a tail clamping mechanism and a tail cutting mechanism.

However, the tail clamping mechanism and the tail cutting mechanism are set independently and need to be driven by two cylinders or electric cylinders. This occupies a lot of machine space, which is not conducive to the design and layout of filling equipment. Moreover, the two cylinders or electric cylinders are difficult to coordinate, require a long time for debugging, have poor stability, and have a slow operating rhythm, which affects the filling production efficiency.

[0024] Example 1:

[0025] like Figure 1 As shown, a filling tube sealing device is installed on a machine base and includes a power component 4, a lifting shaft 3, and an actuation component 1. The power component 4 is installed below the machine base, and the actuation component 1 is installed above the machine base. The lifting shaft 3 passes through the machine base through a bushing 2, and the bushing 2 is installed on the machine base. The power component 4 drives the actuation component 1 to work through the lifting shaft 3.

[0026] like Figure 2 As shown, the actuation component 1 includes a column 11, a lifting seat 12, a fixed seat 13, two pull rods 14, a tail clamping unit, and a tail cutting unit.

The two pull rods 14 are respectively connected to the tail clamping unit and the tail cutting unit. The tail clamping unit and the tail cutting unit are respectively arranged on both sides of the fixed seat 13.

[0027] The filling tube sealing device in this embodiment uses a power component 4 to enable a single power source to drive the tail-cutting unit and the tail-clamping unit to lift and operate simultaneously, which greatly saves space, requires no debugging, and has a fast operating rhythm, which can greatly improve the sealing efficiency.
