Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, and in particular to a packaging barrel equipped with a top-mounted vacuum device. Background Technology

[0002] Packaging drums are storage containers manufactured using injection molding and hollow blow molding. They come in a wide variety of sizes and are primarily used for filling materials to improve their safety. Current packaging drums have a simple structure, using a top lid to ensure internal sealing. However, because a significant amount of air remains inside even when the lid is closed, the safety of the stored contents remains somewhat limited. Utility Model Content

[0003] The technical problem this invention aims to solve is that current packaging barrels have simple structures and limited internal sealing, resulting in low safety of the stored items.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a packaging barrel with a top vacuum device, including a main barrel body, a top barrel cover is provided at the upper opening of the main barrel body, a top guide tube is provided on the upper surface of the top barrel cover, a detachable vacuum extraction cover is threaded on the outer side of the top guide tube, and an inner limiting frame is provided at the inner opening of the top guide tube.

[0005] The outer arc-shaped surface of the top guide tube is an external thread assembly surface.

[0006] The detachable vacuum extraction cover is threaded onto the external threaded mounting surface of the top guide tube.

[0007] The detachable vacuum extraction cover includes an internally threaded assembly tube that is threaded to the top guide tube, a centrifugal air pump that is axially fixed to the upper end of the internally threaded assembly tube, a detachable internal plug, and a magnetically controlled limiting mechanism.

[0008] The diameter of the top guide tube gradually decreases from the outside to the inside.

[0009] The inner wall of the internally threaded assembly tube is provided with a plurality of lateral flip-over grooves for installing and magnetically controlling the limiting mechanism. The lateral flip-over grooves are connected to the inner air inlet of the centrifugal air pump.

[0010] The beneficial effects of this utility model are:

[0011] (1) A packaging barrel with a top vacuum device of the present invention is provided with a detachable vacuum extraction cover by threading a top guide tube on the outer side of the top surface of the top barrel cover. The detachable vacuum extraction cover can quickly remove the air in the barrel, reduce the internal air, and thus enhance the safety of the internal stored items.

[0012] (2) The detachable vacuum extraction cover can not only extract the air inside the barrel, but also test the overall sealing performance of the packaging barrel. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] Figure 1 This is a schematic diagram of the structure of this utility model.

[0015] Figure 2 This is an internal schematic diagram of the detachable vacuum extraction cover assembly end in this utility model. Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Figure 1 and Figure 2 The packaging barrel shown includes a main barrel body 1, a top barrel cover 2 at the upper opening of the main barrel body 1, a top guide tube 3 on the upper surface of the top barrel cover 2, a detachable vacuum extraction cover 4 threaded on the outer side of the top guide tube 3, and an inner limiting frame 5 at the inner opening of the top guide tube 4.

[0019] For threaded assembly, the outer arc-shaped surface of the top guide tube 3 is the external threaded assembly surface.

[0020] To accommodate the threaded assembly, the detachable vacuum extraction cover 4 is threaded onto the external threaded mounting surface of the top guide tube 3.

[0021] To facilitate electronically controlled vacuuming, the detachable vacuum extraction cover 4 includes an internally threaded assembly tube 41 that is threadedly fitted to the top guide tube 3, a centrifugal vacuum pump 42 that is axially fixed to the upper end of the internally threaded assembly tube 41, a detachable internal plug 43, and a magnetically controlled limiting mechanism 44.

[0022] The centrifugal pump 42 operates at high speed, drawing air out of the main barrel 1 and the top guide pipe 3. When the internal air pressure drops to the set minimum value, the magnetic control limit mechanism 44 closes. The detachable internal plug 43, no longer limited by the magnetic control limit mechanism 44, is then drawn into the top guide pipe 3, thus closing the top guide pipe 3. The detachable vacuum extraction cover 4 is then removed, and an internally threaded sealing cap is threaded onto the outside of the top guide pipe 3 to enhance safety.

[0023] To improve the internal sealing effect, the inner diameter of the top guide pipe 3 gradually decreases from the outside to the inside.

[0024] To facilitate internal flipping and limiting, and to guide the flow, two lateral flipping grooves 411 are provided on the inner wall of the internal thread assembly tube 41 for installing and magnetically controlling the limiting mechanism 44. The lateral flipping grooves 411 are connected to the inner air inlet of the centrifugal air pump 42.

[0025] The outer side of the internally threaded assembly pipe 41 is connected to the inner air inlet of the centrifugal air pump 42 through an external guide pipe. An electric control valve is installed on the external guide pipe to control the flow state inside the external guide pipe.

[0026] The measurement and control limiting mechanism 44 includes a flipping limiting arm installed inside the lateral flipping groove 411, an electromagnet installed inside the lateral flipping groove 411, and an iron spring. After the electromagnet is energized and started, the iron spring contracts, causing the flipping limiting arm to flip inside the internal threaded assembly tube 41, limiting the removable internal plug 43. This prevents the removable internal plug 43 from being inserted into the top guide tube 3 during internal vacuuming.

[0027] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
