Abstract
The utility model discloses an uncapping mechanism of a double-chamber vacuum package machine. The uncapping mechanism of the double-chamber vacuum package machine comprises a vacuum chamber and long shafts, wherein the two long shafts are arranged on the middle portion of the vacuum chamber through flange bearings. Connecting bars are respectively arranged at both ends of each long shaft. The other end of each connecting bar is connected with a vacuum cap. Spring pull bars are respectively arranged on the long shafts. Both sides of the spring pull bars are connected with one end of an adjusting screw through rotating shafts. A tension spring is arranged on the adjusting screw. Meanwhile, the other end of the adjusting screw is fixed on a tension spring base through an adjusting screw base. In addition, the tension spring base is arranged on a reinforcing rib inside the vacuum chamber. The uncapping mechanism of the double-chamber vacuum package machine has the advantages that the vacuum cap can easily and flexibly work. At the same time, the purposes that weight of the vacuum cap is divided equally to the two long shafts and stress on one single long shaft is decreased are achieved. Under the effect of the vacuum cap with the same weight, the diameter of the long shafts can be smaller than that of long shafts in a prior designed structure, materials are saved, meanwhile, the service life of the spring is prolonged, and the uncapping mechanism of the double-chamber vacuum package machine is simple in structure and low in production cost.
Description
Technical field
The utility model relates to a kind of cap-opening mechanism, particularly a kind of cap-opening mechanism of double-chamber vacuum packing machine.
Background technology
The mode of the uncapping major part of present domestic double-chamber vacuum packing machine has adopted extension spring mechanism, the mounting means of extension spring mechanism is different, but machine something in common in the course of the work is to only have a major axis to be subjected to all the time the pulling force of spring, another root major axis substantially do not stress (being subjected to initial tension of spring).Therefore major axis is so stressed for a long time, is prone to flexural deformation.As increase the bending strength of major axis, and need to increase major diameter or improve material etc., must increase cost like this.In addition, the spring of present domestic usefulness is circle hook-type spring basically, and this spring such as heat treatment are bad, is prone to the phenomenon that fractures after the circle hook is in long-time stretching work.
Summary of the invention
For the shortcoming of the cap-opening mechanism of existing double-chamber vacuum packing machine, the utility model provides a kind of cap-opening mechanism of novel double-chamber vacuum packing machine.
To achieve these goals, the utility model institute Adopts measure
A kind of cap-opening mechanism of double-chamber vacuum packing machine comprises vacuum chamber, major axis, and described vacuum chamber middle part is provided with two major axis by flange bearing, and the major axis two ends are provided with connecting rod, and the connecting rod other end is connected with vacuum cover; Be provided with the spring pull bar on the major axis; Spring pull bar both sides all are connected with adjusting screw(rod) one end by rotating shaft, are provided with extension spring on the adjusting screw(rod); Simultaneously, the adjusting screw(rod) other end is fixed on the spring base by the adjusting screw(rod) seat; In addition, spring base is arranged on the interior reinforced rib of vacuum chamber.
The beneficial effects of the utility model: the utility model works together more very light, flexible by vacuum cover.Simultaneously, solved in the weight of vacuum cover and divided equally on two major axis, reduced the stressed of single major axis.Under the effect of identical weight vacuum cover, the major diameter in the comparable present project organization of the diameter of major axis is little, economization material, prolonged simultaneously spring service life; Simple in structure, productive costs is low.

The specific embodiment
A kind of cap-opening mechanism of double-chamber vacuum packing machine as shown in Figure 1 and Figure 2, comprises vacuum chamber 1, major axis 2, and described vacuum chamber 1 middle part is provided with two major axis 2 by flange bearing, and major axis 2 two ends are provided with connecting rod 9, and connecting rod 9 other ends are connected with vacuum cover 10; Be provided with spring pull bar 4 on the major axis 2; Spring pull bar 4 both sides all are connected with adjusting screw(rod) 5 one ends by rotating shaft, are provided with extension spring 3 on the adjusting screw(rod) 5; Simultaneously, adjusting screw(rod) 5 other ends are fixed on the spring base 8 by adjusting screw(rod) seat 6; In addition, spring base 8 is arranged on the reinforced rib 7 in the vacuum chamber 1.In the actual implementation process of patent, when the operator is rocked to vacuum cover 10 in the process of Fig. 3 position by Fig. 1 position, connecting rod 9 will swing with vacuum cover 10, and then connecting rod 9 drives major axis 2 and swings with spring pull bar 4; The angle that swings along with spring pull bar 4 is larger, and as shown in Figure 3, the stretching that drives two extension springs 3 in 4 left sides of spring pull bar is longer, and two extension springs 3 in spring pull bar 4 right sides almost are in not extended state, and therefore, the application force of 3 pairs of major axis 2 of extension spring this moment is also larger.Plane certain altitude on vacuum cover 10 is rocked near vacuum chamber 1, as shown in Figure 3, the moment of torsion sum that the moment of torsion that the gravity of vacuum cover 10 produces major axis 2 will produce greater than the 3 pairs of major axis of spring pull bar 4 both sides spring extension springs 2 on the vacuum chamber 1 left side major axis 2, therefore vacuum cover 10 will be pressed together on plane on the vacuum chamber 1 by the deadweight pulsation-free, and machine will be started working automatically.When machine was finished the work, as shown in Figure 3, the operator waved vacuum cover 10 to the process of Fig. 4 position by Fig. 3 position, and the spring pull bar 4 both sides spring extension springs 3 on the vacuum chamber 1 left side major axis 2 will slowly be shunk, as shown in Figure 4 state; Spring pull bar 4 both sides spring extension springs 3 on the vacuum chamber 1 right side major axis 2 will slowly be stretched, as shown in Figure 4 state; Plane certain altitude on vacuum cover 10 is rocked near vacuum chamber 1, the moment of torsion sum that the elastic force of the spring pull bar 4 both sides spring extension springs 3 of the moment of torsion that the gravity of vacuum cover 10 produces major axis 2 on will vacuum chamber 1 right side major axis 2 produces major axis 2, therefore vacuum cover 10 will be pressed together on plane on the vacuum chamber 1 by the deadweight pulsation-free, and machine will be started working automatically.
Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in this area.
