Description

Technical Field

[0001] The utility model belongs to the technical field of flower tea packaging, and particularly relates to a vacuum packaging machine for flower tea. Background Technique

[0002] The vacuum packaging machine for flower tea seals the vacuum chamber, enabling the negative pressure suction system to evacuate the air from the flower tea packaging and perform heat sealing on the flower tea packaging to complete the vacuum packaging of the flower tea. The vacuum chamber of the vacuum packaging machine for flower tea is closed by a cover body and a sealing ring installed at the bottom to prevent external air from entering the vacuum chamber. However, during actual use, since the corresponding fitting parts of the sealing ring are directly exposed, they may be damaged and deformed by external objects, resulting in a decrease in the sealing effect between the sealing ring and the corresponding fitting parts. Moreover, after long-term use, the sealing ring will experience a decrease in its own sealing effect due to oxidation and wear, etc., which will further lead to a decrease in the negative pressure suction effect of the vacuum chamber and affect the vacuum packaging effect of the flower tea. It is necessary for the staff to gradually check each component of the vacuum packaging machine for flower tea to find out the reason for the poor negative pressure suction effect of the vacuum chamber, which is inconvenient to operate. Summary of the Utility Model

[0020] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: a flower tea vacuum packaging machine, including a flower tea vacuum packaging machine main body 1, a vacuum chamber cover 11 and a sealing ring 12. Flip-type protective covers 2 are provided on all four sides of the flower tea vacuum packaging machine main body 1. A torsion spring rotating shaft rod 21 is rotatably connected inside the flip-type protective cover 2, and the torsion spring rotating shaft rod 21 is fixedly connected to the outer wall of the flower tea vacuum packaging machine main body 1. A sealing extrusion ring plate 3 is fixedly connected to the bottom end of the vacuum chamber cover 11. Below the sealing extrusion ring plate 3 is an "L"-shaped support ring plate 4. A plastic film bag 41 is fixedly connected to the bottom end of the "L"-shaped support ring plate 4, and an air flow communication hole 42 is opened at the bottom end of the "L"-shaped support ring plate 4.

[0021] In this implementation: when it is necessary to vacuum pack flower tea, the staff flips and opens the vacuum chamber cover 11, and the sealing extrusion ring plate 3 moves together with the vacuum chamber cover 11. After the sealing extrusion ring plate 3 is separated from the flip-type protective cover 2, the flip-type protective cover 2 flips and covers the top end of the flower tea vacuum packaging machine main body 1 under the elastic force of the torsion spring rotating shaft rod 21, and the top surface of the flower tea vacuum packaging machine main body 1 is protected by the flip-type protective cover 2 to prevent the top surface of the flower tea vacuum packaging machine main body 1 from being damaged by collision and deformed, so as to avoid the sealing effect between the flower tea vacuum packaging machine main body 1 and the sealing ring 12 from decreasing. Subsequently, the staff installs the flower tea package at the corresponding position inside the flower tea vacuum packaging machine main body 1. After the flower tea package is placed, the staff flips and closes the vacuum chamber cover 11, and the various components inside the flower tea vacuum packaging machine main body 1 complete the vacuum pumping and sealing of the flower tea package. During the process of flipping and closing the vacuum chamber cover 11, the sealing extrusion ring plate 3 squeezes the flip-type protective cover 2, driving the flip-type protective cover 2 to flip and open, which will not hinder the contact between the sealing ring 12 and the flower tea vacuum packaging machine main body 1. As the sealing extrusion ring plate 3 further moves downward, the sealing extrusion ring plate 3 contacts the extrusion sealing strip 43, and the extrusion sealing strip 43 seals the gap between the sealing extrusion ring plate 3 and the "L"-shaped support ring plate 4. When the sealing effect between the sealing ring 12 and the flower tea vacuum packaging machine main body 1 is not good, the air inside the "L"-shaped support ring plate 4 will be sucked into the flower tea vacuum packaging machine main body 1, and the plastic film bag 41 will shrink under the action of the internal low air pressure and the external high air pressure. The staff can intuitively observe the change of the plastic film bag 41, so as to judge whether the flower tea vacuum packaging machine main body 1 and the sealing ring 12 are in a good sealing state, without the staff gradually checking whether each component of the equipment is damaged, and the use is more convenient. After the vacuum chamber cover 11 is flipped and opened again, the "L"-shaped support ring plate 4 is in an atmospheric pressure state, and the plastic film bag 41 unfolds downward under the action of the suspension ball 44 for reuse.

[0022] An elastic extrusion block 13 is fixedly connected to one side of the main body 1 of the scented tea vacuum packaging machine, and the elastic extrusion block 13 is in contact with the torsion spring rotating shaft 21; by providing the elastic extrusion block 13, an initial force for flipping the flip protective cover 2 can be applied to the flip protective cover 2, so that the flip protective cover 2 can be in an inclined state, so that the flip protective cover 2 can be flipped more smoothly to cover the top surface of the main body 1 of the scented tea vacuum packaging machine.

[0023] The flip protective cover plate 2 corresponds to the sealing extrusion ring plate 3 in position, the flip protective cover plate 2 does not contact the vacuum chamber cover 11, and the flip protective cover plate 2 does not contact the sealing ring 12; the sealing extrusion ring plate 3 has a longer length and corresponds to the position of the flip protective cover plate 2, so that the flip protective cover plate 2 can squeeze the flip protective cover plate 2, driving the flip protective cover plate 2 to flip, and the flip protective cover plate 2 will not contact the vacuum chamber cover 11 and the sealing ring 12 during the flipping process, thereby avoiding blocking the flipping of the flip protective cover plate 2.

[0024] An extrusion sealing strip 43 is fixedly connected to the inner wall of the "L"-shaped support ring plate 4, and the extrusion sealing strip 43 is in contact with the sealing extrusion ring plate 3; by setting the extrusion sealing strip 43, it can interfere with the sealing extrusion ring plate 3 to play a sealing role, preventing external airflow from entering the "L"-shaped support ring plate 4, so that the plastic film bag 41 can be deformed under the action of negative pressure, and can play a secondary sealing role, thereby increasing the sealing effect when the vacuum chamber cover 11 is flipped closed.

[0025] The bottom end of the plastic film bag 41 is fixedly connected to a hanging ball 44 for driving the plastic film bag 41 to fall; by setting the hanging ball 44, the plastic film bag 41 can be driven to expand and open under normal pressure inside the plastic film bag 41, and the staff does not need to manually expand the plastic film bag 41.

[0026] A flip protection plate 45 is hinged at the bottom end of the "L"-shaped support ring plate 4, and the length of the flip protection plate 45 is greater than the bottom height of the plastic film bag 41; by setting the flip protection plate 45, the plastic film bag 41 can be protected to prevent the plastic film bag 41 from being squeezed by staff moving around the equipment.

[0027] The width of the extrusion sealing strips 43 on the front and rear sides is greater than the width of the extrusion sealing strips 43 on the left and right sides; the movement trajectory of the sealing extrusion ring plates 3 on the front and rear sides is arc-shaped, and the wider extrusion sealing strips 43 can produce greater deformation, providing space for the movement of the sealing extrusion ring plates 3.

[0028] Working principle and usage process of the utility model: The staff flips and opens the vacuum chamber cover 11. The sealing extrusion ring plate 3 moves together with the vacuum chamber cover 11. After the sealing extrusion ring plate 3 is separated from contact with the flip-type protective cover plate 2, the flip-type protective cover plate 2 flips under the elastic force of the torsion spring rotating shaft rod 21 and covers the top of the flower tea vacuum packaging machine main body 1. The top surface of the flower tea vacuum packaging machine main body 1 is protected by the flip-type protective cover plate 2 to prevent the top surface of the flower tea vacuum packaging machine main body 1 from being damaged by collision and deformed. Subsequently, the staff installs the flower tea package at the corresponding position in the flower tea vacuum packaging machine main body 1. After the flower tea package is placed, the staff flips and closes the vacuum chamber cover 11. Each component in the flower tea vacuum packaging machine main body 1 completes the vacuum pumping and sealing of the flower tea package. During the process of flipping and closing the vacuum chamber cover 11, the sealing extrusion ring plate 3 squeezes the flip-type protective cover plate 2, driving the flip-type protective cover plate 2 to flip and open, which will not hinder the contact between the sealing ring 12 and the flower tea vacuum packaging machine main body 1. As the sealing extrusion ring plate 3 moves further downward, the sealing extrusion ring plate 3 contacts the extrusion sealing strip 43. The extrusion sealing strip 43 seals the gap between the sealing extrusion ring plate 3 and the "L"-shaped support ring plate 4. When the sealing effect between the sealing ring 12 and the flower tea vacuum packaging machine main body 1 is not good, the air inside the "L"-shaped support ring plate 4 will be sucked into the flower tea vacuum packaging machine main body 1. The plastic film bag 41 will shrink under the action of the internal low air pressure and the external high air pressure. The staff can intuitively observe the change of the plastic film bag 41, so as to judge whether the flower tea vacuum packaging machine main body 1 and the sealing ring 12 are in a good sealing state.
