Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0021] refer to Figure 1 to Figure 4 , a plunger driving mechanism provided by an embodiment of the present invention includes a plunger body 1 for opening / blocking the opening of a container. The plunger body 1 is provided with an air pressure channel A for communicating the outside of the container with the inside of the container. The plunger The body 1 is provided with a movable pressure relief sealing head 12 for opening / sealing the air pressure channel A, the pressure relief sealing head 12 is connected with a pressure relief rod 11, and the pressure relief rod 11 extends out of the plunger body 1 and connects with a drive assembly 70 is connected and moves up and down under drive assembly 70 drives.
[0022] In this embodiment, the opening can be a discharge port, a f...

The invention belongs to the technical field of sealing elements, and provides a plunger driving mechanism and device. The plunger driving mechanism comprises a plunger body used for opening / blockingan opening of a container, the plunger body is provided with an air pressure channel, the plunger body is internally provided with a movable pressure relief sealing head used for opening / sealing the air pressure channel, the pressure relief sealing head is connected with a pressure relief rod, and the pressure relief rod extends out of the plunger body to be connected with a driving assembly and is driven by the driving assembly to move up and down. According to the plunger driving mechanism, the air pressure channel communicated with the container is formed in the plunger body, the pressure relief sealing head is directly arranged in the plunger, and the driving assembly drives the pressure relief rod to move to drive the pressure relief sealing head and the pressure relief rod to move soas to open / seal the air pressure channel and open / block the opening of the container; and therefore, one driving assembly drives the two components to move to achieve material taking and pressure relief operation, a pressure relief opening does not need to be additionally formed in the container, a pressure relief piece does not need to be additionally installed on the container, the structure iscompact, reliability is higher, and application is wider.
Description
technical field [0001] The invention belongs to the technical field of seals, and in particular relates to a plunger driving mechanism and a device using the plunger driving mechanism. Background technique [0002] At present, some containers or material storage equipment are provided with automatic discharge ports, and the automatic discharge ports are often opened or closed by a plunger driven by a motor. Due to the high requirements for storage conditions of some materials, after the plunger closes the discharge port, it is necessary to vacuumize the container or storage equipment. In this way, due to the large negative pressure inside the container or storage device, when the discharge port is opened again, In general, it is difficult to pull out the plunger directly to open the discharge port. It is necessary to set a pressure relief port on the container or storage equipment, and set a pressure relief valve at the pressure relief port. First, release the pressure throu...
