Abstract
Description
Technical Field
[0001] The utility model relates to the field of packaging equipment, in particular to a multi-column machine horizontal sealing guide shaft support structure. Background Art
[0002] In the traditional multi-column machine horizontal sealing mechanism, the front sealing plate and the rear sealing plate are respectively driven by their corresponding power shafts. However, in the actual process, we found that the service life of the power shaft of the front sealing plate is much shorter than expected. Since there is only one power shaft for the front sealing plate, and its diameter is short, and the front sealing plate is far away from the horizontal sealing fixed support base. After technical analysis, it is found that, firstly, due to the lever effect, the power shaft of the front sealing plate needs to bear the moment at both ends, and due to the distance relationship, the lever effect will be amplified on the power shaft of the front sealing plate, exacerbating the force it receives; secondly, bending moment and shear force, the power shaft of the front sealing plate not only has to bear the axial forces from the front sealing plate and the rear sealing plate, but also has to bear the bending moment and shear force. The combination of these forces will cause stress concentration on the power shaft of the front sealing plate, thereby increasing its stress. Although the situation of the rear sealing plate is slightly better than that of the front sealing plate, its power shaft also bears a lot of pressure. Through the above technical analysis, it is not difficult to find that the current structure of the existing technology is obviously very unreasonable.
[0003] In order to solve the above problems, a series of improvements have been made. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a multi-column machine horizontal sealing guide shaft support structure to overcome the above-mentioned drawbacks and deficiencies of the existing technology.
[0005] A multi-column machine horizontal sealing guide shaft support structure includes: a front sealing plate, a front sealing plate power shaft, a guiding support shaft, a horizontal sealing fixed support base, a rear sealing plate and a rear sealing plate power shaft. The bottom ends on both sides of the front sealing plate are connected to one end of the guiding support shaft, the top ends on both sides of the front sealing plate are connected to one end of the front sealing plate power shaft, the guiding support shaft and the front sealing plate power shaft are connected through the rear sealing plate, the top ends on both sides of the rear sealing plate are connected to the rear sealing plate power shaft, the other ends of the front sealing plate power shaft and the guiding support shaft are connected to the horizontal sealing fixed support base, and the horizontal sealing fixed support base is connected to the swing arm.
[0006] Further, the number of the guiding support shafts is 2.
[0007] Advantages of the Utility Model
[0008] Compared with the traditional technology, the utility model provides stronger support force for the front sealing plate by re-designing the structures and connection relationships of the front sealing plate power shaft, the guiding support shaft and the rear sealing plate power shaft, and improves the service life of the overall parts.

[0013] The following further describes the present utility model in conjunction with specific embodiments. It should be understood that the following embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model.
[0014] Embodiment 1
[0015] Figure 1 This is a schematic structural diagram of the present utility model. Figure 2 This is a schematic structural diagram of a traditional device.
[0016] As Figure 1 shown, a multi-column machine horizontal sealing guide shaft support structure includes: a front sealing plate 100, a front sealing plate power shaft 200, a guiding and supporting shaft 300, a horizontal sealing fixed support base 400, a rear sealing plate 500, and a rear sealing plate power shaft 600. The bottom ends on both sides of the front sealing plate 100 are connected to one end of the guiding and supporting shaft 300, the top ends on both sides of the front sealing plate 100 are connected to one end of the front sealing plate power shaft 200, the guiding and supporting shaft 300 and the front sealing plate power shaft 200 are connected through the rear sealing plate 500, the top ends on both sides of the rear sealing plate 500 are connected to the rear sealing plate power shaft 600, the other ends of the front sealing plate power shaft 200 and the guiding and supporting shaft 300 are connected to the horizontal sealing fixed support base 400, and the horizontal sealing fixed support base 400 is connected to the swing arm.
[0017] The number of guiding and supporting shafts 300 is 2.
[0018] The working principle of the present utility model is as follows: The front sealing plate 100 moves back and forth by two left and right front sealing plate power shafts 200. Since the number of guiding and supporting shafts 300 is 2, a total of 4 guiding and supporting shafts 300 on the left and right play a role of supporting and guiding. The weight of the entire front sealing plate is supported by a total of 6 shafts on the left and right. And since the front sealing plate power shaft 200 and the guiding and supporting shaft 300 both penetrate the rear sealing plate 500, they are both connected to the horizontal sealing fixed support base 400. Therefore, the front sealing plate 100 is supported on the horizontal sealing fixed support base 400 through the front sealing plate power shaft 200 and the guiding and supporting shaft 300.
[0019] The rear sealing plate is moved forward and backward by the two rear sealing plate power shafts 600 on the left and right. Since the front sealing plate power shaft 200 and the guide support shaft 300 penetrate the rear sealing plate 500, the rear sealing plate is actually supported and guided by the remaining four guide support shafts 300 on the left and right. The weight of the entire front sealing plate 100 is actually supported by a total of eight shafts on the left and right: two front sealing plate power shafts 200, four guide support shafts 300 and two rear sealing plate power shafts 600, and supported on the horizontal sealing fixed support base 400.
[0020] like Figure 2 As shown, compared with the traditional technology, the utility model firstly has a more uniform force distribution: increasing the number of shafts, so that the weight of the front sealing plate and the rear sealing plate is distributed on more shafts, thereby reducing the force borne by each shaft. This helps to reduce the stress of a single shaft and improve the stability of the overall structure. Secondly, reduce stress concentration: more guide support shafts 300 can disperse external forces and reduce stress concentration. Stress concentration is one of the main causes of structural fatigue and damage. By dispersing stress, the service life of the structure can be extended. Thirdly, improve stiffness and stability: increase the number of guide support shafts 300, improve the stiffness and stability of the structure. More support points make the front sealing plate 100 and the rear sealing plate 500 deform less when subjected to force, thereby improving the stiffness and stability of the overall structure. Finally, the improved connection method: the front sealing plate power shaft 200 and the guide support shaft 300 pass through the rear sealing plate 500 and are connected to the horizontal sealing fixed support base 400. This connection method makes the force of the front sealing plate 100 and the rear sealing plate 500 more reasonable and reduces the stress concentration at the connection point.
[0021] In general, by adding the guide support shaft 300 and improving the connection method, the stress conditions of the front cover plate 100 and the rear cover plate 500 are significantly improved. The stability and durability of the structure are improved, the stress concentration phenomenon of a single shaft is reduced, and the service life of the structure is extended.
[0022] The specific implementation modes of the present invention are described above, but the present invention is not limited thereto. The present invention can also have various changes without departing from the purpose of the present invention.
