Description

Technical Field

[0001] This utility model relates to the technical field of horizontal sealing devices, specifically a horizontal sealing device for multi-layer aseptic composite film filling equipment. Background Technology

[0002] In the filling process of multi-layer aseptic composite films, the horizontal sealing device of the filling equipment plays a crucial role. Currently, most multi-layer aseptic composite film filling equipment on the market mainly uses mechanical transmission for its horizontal sealing device. This traditional mechanical transmission method has gradually revealed some problems over long-term use. On the one hand, the mechanical transmission structure is often quite complex, composed of numerous precise and interconnected mechanical parts. This not only increases the difficulty of equipment design and manufacturing but also makes the installation and commissioning process cumbersome, requiring professional technicians to spend a significant amount of time and effort on operation. On the other hand, in daily operation, the complex mechanical structure makes operation relatively inconvenient, requiring operators to undergo specialized training to master the equipment's operating skills. Moreover, once the equipment malfunctions, due to the large number of mechanical parts and the complex structure, repair is difficult, requiring professional maintenance personnel to check and repair each component one by one. This not only consumes a lot of repair time but also leads to high maintenance costs.

[0003] Therefore, there is an urgent need for a horizontal sealing device for multi-layer aseptic composite film filling equipment that is simple in structure, easy to operate, and has low maintenance costs. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a horizontal sealing device for a multi-layer aseptic composite film filling equipment to solve the problems involved in the background art.

[0010] Furthermore, a guide sleeve oilless bearing is provided between the front cylinder fixing plate and the rear transverse sealing fixing plate, and the first guide rod and the cylinder rod extension rod are both located inside the guide sleeve oilless bearing.

[0011] The first guide rod passes through the rear horizontal sealing plate and connects to the front horizontal sealing plate.

Each of the two guide rod fixing plates 10 is provided with a first guide rod 11. The first guide rod 11 and the cylinder rod extension rod 3 both pass through the cylinder front fixing plate 1 and are connected to the horizontal sealing mechanism.

[0025] The transverse sealing mechanism includes a rear transverse sealing fixing plate 12, a front transverse sealing fixing plate 13, two second guide rods 14 disposed between the front transverse sealing fixing plate 13 and the rear transverse sealing fixing plate 12, and a front transverse sealing mechanism and a rear transverse sealing mechanism sleeved between the two second guide rods 14. A guide sleeve oil-free bearing 15 is provided between the cylinder front fixing plate 1 and the rear transverse sealing fixing plate 12. The first guide rod 11 and the cylinder rod extension rod 3 are both disposed within the guide sleeve oil-free bearing 15. The first guide rod 11 passes through the rear transverse sealing fixing plate 12 and connects to the front transverse sealing fixing plate 13. The cylinder rod extension rod 3 is connected to the rear transverse sealing fixing plate 12. A rear transverse sealing positioning guide seat 16 is provided on the guide sleeve oil-free bearing 15 outside the first guide rod 11. The second guide rod 14 passes through the rear transverse sealing fixing plate 12 and is fixedly connected to the rear transverse sealing positioning guide seat 16.

[0026] The front and rear horizontal sealing mechanisms have identical structures and are arranged opposite to each other.

[0027] The double-rod double-acting cylinder 2 is provided with hole A and hole B.

[0028] Working principle:

[0029] When the multi-layer sterile composite film is in production, the packaging film passes between the front horizontal sealing mechanism and the rear horizontal sealing mechanism.

[0030] This application uses fixing screws to fix the front fixing plate 14 of the cylinder to the multi-layer sterile composite film equipment. When air is supplied to port A of the double-rod double-acting cylinder 2, the cylinder rod 4 drives the cylinder rod extension rod 3 to push the rear horizontal sealing mechanism forward. At the same time, the forward movement of the cylinder rod 4 will drive the linkage mechanism to move, which in turn causes the first guide rod 11 to move backward, and the front horizontal sealing mechanism to move backward. At this time, the packaging film is between the front horizontal sealing mechanism and the rear horizontal sealing mechanism. The front and rear horizontal sealing mechanisms move relative to each other at the same time, and come into contact with the packaging film to generate pressure cutting and heat sealing. After sealing is completed, air is supplied to port B of the double-rod double-acting cylinder 2. The cylinder rod 4 drives the cylinder rod extension rod 3 to move backward, pulling the rear horizontal sealing mechanism to move backward. At the same time, the linkage mechanism pulls the first guide rod 11 forward, pulling the front horizontal sealing mechanism forward, so that the front and rear horizontal sealing mechanisms open, and the horizontal sealing frame 17 is reset under the action of the horizontal sealing spring 19 and the second guide rod 14.
