Description

Technical Field

[0001] This application relates to the field of capping, and more specifically, to a device for facilitating the installation of a cap onto a tank. Background Technology

[0002] The main method of installing the lid onto the tank is by using a pressure capping method. The pressure capping process mainly involves applying downward pressure to the lid with a flat surface, and then the lid is fastened to the tank under pressure.

[0003] However, in some cases, the lid and the can are not perfectly aligned, which can lead to difficulties in pressing the lid onto the can. Utility Model Content

[0006] Furthermore, the edge of the pressing surface has an annular pressing portion, which is located above the protrusion; the annular pressing portion matches the edge of the cover.

[0007] Furthermore, the protrusion has a circular surface and an arc-shaped surface, the circular surface being parallel to the pressing surface, and the arc-shaped surface being connected to the circular surface.

[0008] Furthermore, an elastic pad is provided below the annular pressure section.

[0009] Furthermore, the device further includes: a first driving member and a second driving member; the pressure cover structure includes: a first pressure plate and a second pressure plate; the first pressure plate forms the protrusion, and the second pressure plate forms the annular pressure portion; the first driving member is used to drive the first pressure plate to move up and down, and the second driving member is used to drive the second pressure plate to move up and down.

[0010] Furthermore, a connecting ring is provided on the outer side of the second pressure plate, and the connecting ring matches the cover; a buffer pad is provided on the inner wall of the connecting ring.

[0011] The beneficial effect of this application is that the middle part of the lid is first recessed, so that the edge of the lid will be raised outward, so that the lid can be fastened to the can even if it is not completely aligned, thus making it easier to press the lid into the can.

[0025] Reference Figure 1-3 ,

[0026] A device for facilitating the installation of a lid onto a can includes: a lid-feeding structure, a lid-pressing structure 1, and a conveying structure 2. The conveying structure 2 transports the can to the lid-feeding structure; the lid-feeding structure places the lid onto the can; the lid-pressing structure 1 applies downward pressure to the lid to secure it to the can; wherein the lid-pressing structure 1 has a pressing surface with a protrusion in the center. The protrusion allows downward pressure to be applied to the center of the lid initially, causing the center of the lid to indent, reducing the binding force on the edges of the lid from the center, or causing the edges of the lid to expand outwards or fold upwards, making it easier for the lid to be secured to the can. After sealing, the protrusion leaves the lid, and the lid, due to its own resilience, returns to its original state, increasing the sealing speed. The lid-feeding structure can be a robotic arm, which will not be described further. The conveying structure 2 uses a conveyor to directly transport the can. Alternatively, the conveying structure 2 can use a conveyor, a first cylinder, and a second cylinder to turn and transport the tank to the capping structure.

[0027] Specifically, the edge of the pressing surface has an annular pressing part 61, which is located above the protrusion; the annular pressing part 61 matches the edge of the cover.

[0028] Specifically, the protrusion has a circular surface and an arc-shaped surface 3. The circular surface is parallel to the pressing surface, and the arc-shaped surface 3 is connected to the circular surface. The arc-shaped surface 3 is located above the circular surface and is connected to it. The arc-shaped surface 3 is designed to better protect the cover and prevent marks from being left after the cover is deformed. For example, if the arc-shaped surface 3 were a straight surface, the connection between the straight surface and the circular surface would be abrupt, making it easy to leave deformed marks on the cover.

[0029] Specifically, an elastic pad is provided below the annular pressure part 61.

[0030] Specifically, the device further includes: a first driving member 4 and a second driving member 5; the capping structure 1 includes: a first pressure plate 6 and a second pressure plate 7; the first pressure plate 6 forms the protrusion, and the second pressure plate 7 forms the annular pressure part 61; the first driving member 4 is used to drive the first pressure plate 6 to move up and down, and the second driving member 5 is used to drive the second pressure plate 7 to move up and down. Both the first driving member 4 and the second driving member 5 are pneumatic cylinders or hydraulic cylinders. After the cap is closed, the first driving member 4 first drives the first pressure plate 6 to move up, so that the protrusion moves away from the cap. At this time, the annular pressure part 61 presses the cap onto the can, which facilitates the cap's restoration.

[0031] Specifically, a connecting ring is provided on the outer side of the second pressure plate 7, and the connecting ring matches the cover; a buffer pad is provided on the inner wall of the connecting ring.

[0032] In some designs, a vacuum suction cup is installed on the protrusion to make it easier for the cover to return to its original state.

[0033] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
