Description

[Detailed description of the invention] This invention is a two-stage can lid sealer that improves the tightening mechanism of a can lid sealing machine that seals metal rings such as can lids and can lid seal caps, making the sealing more complete and reliable. It is related to the device.

Conventionally, various sealing machines of this type have been provided, but these sealing machines seal the lid by tightening it inward using a plurality of claws provided in an annular shape from the outer end of the lid.

However, with this type of sealing, the end of the lid curls outward, resulting in frequent accidents such as damage to the right to transport and move the can, which is dangerous.

Therefore, this invention improves the sealing mechanism of conventional sealing machines, and uses a mechanism that tightens the can lid from the outside to the inside and then presses it further upwards, allowing for complete sealing through a series of manual operations. This can be explained based on the drawings as follows.

As shown in FIG. 1, a handle attachment part 10 is fixed to the upper part of the center pipe 1, and handles 8, 8' are rotatably provided thereon, and interlocking rods 11, 11 are attached to the lower part of the handles 8, 8'. ' is slidably provided, and the interlocking rod attachment part 13 is provided at the lower part of the interlocking rod 11.11'.
Attach the claw opening/closing lid 1 to the lower part of the interlocking rod attachment part 13.
2, and then attach the claw rod mounting board 1 to the bottom of the center pipe 1.
6 is fixed, and a plurality of pawl rods 6 are provided on the outer periphery of the pawl rods 6 whose lower part is opened by springs 15, and pawls 7 are provided at the bottom of the pawl rods 6. In a can lid sealing device provided with a bottom plate 5 that is integrated with a bottom plate suspension shaft 5' that can freely slide up and down, the bottom plate suspension shaft 5'
An adjustment bolt 4 is provided on the upper part of the center pipe 1, and a vertically elongated sliding groove 3 is provided in the midsection of the center pipe 1. The pressing pin 2 is fitted into this sliding groove 3 and fixed to the interlocking rod attachment part 13, and the claw 7 is Curve inward like a fishhook.

This is based on the above structure, but when this is actually used for sealing, it is as follows.

As shown in FIG. 1, a lid 19 is sealed over the can 18.
When the sealing machine is placed on top of the sealing machine and the handles 8 and 8' are opened to the left and right, the hook-shaped tips of the handles 8 and 8' descend to open the interlocking rod 11. .11' is lowered, and the interlocking rod attachment part 13, claw opening/closing board 12, and pressing pin 2 are lowered.

At this time, the claw rods 6, 6' are pushed outward and opened according to the tapered shape of the outer surface of the claw opening/closing board 12, and the pins 17°17'
The lower claws 7, 7' of the claw rods 6, 6' move inward using the fulcrums to press the periphery of the lid 19 and seal it.

The steps up to this point are the same as before, but the handles 8 and 8 are
′ is opened to the left and right, the interlocking rod 11.
The interlocking rod attachment part 13 and the claw opening/closing board 12 are lowered, but at the same time, the pressure pin lowering along the sliding groove 3 exerts a force that tries to lower the bottom plate hanging shaft 5' and the bottom plate 5 via the adjustment bolt 4. However, since the bottom plate 5 is placed on the can and does not descend, the claw rod mounting plate 16 is actually pushed upward, and the claws 7 curved inward into a fishhook shape. , 7' press the periphery of the lid 19 further upwards to complete the seal.

In order to make it easier to understand the series of operations, the above explanation of the solid sealing process is based on the symmetrical positions of the claws 6°6', 7,
Only the operation of ' is explained with reference to the drawings, and a plurality of pawl rods 6 are actually provided on the periphery of the pawl rod mounting plate 16.

The most distinctive feature of the present invention is that the center pipe 1 is provided with a sliding groove 3, the pressing pin 2 is fitted into this groove and fixed to the interlocking rod attachment part 13, and the claw 7 is curved inward into a fishhook shape. With this, by simply opening the handles 8 and 8' to the left and right,
The two-stage complete sealing method, in which the lid of the can is pressed inward from the sides and then further upwards, increases the strength of the can body and allows the lid plate to be completely sealed even with thin materials, leading to cost reductions. It is something.

As described above, the present invention is an excellent device that completely seals the can lid and solves the danger of holes caused by warping of the periphery of the can after sealing.

[Brief explanation of the drawing]

Figures 1, 2, and 3 show a series of sealing processes of the sealing machine using the present invention. Figure 1 shows the state before operation, and Figure 2 shows the can lid being opened from the side. FIG. 3 shows the pressed state, and FIG. 3 shows the completely sealed state. 1 is the center pipe, 2 is the pressing pin, 3 is the sliding groove, 4 is the adjustment bolt, 5 is the bottom plate, 5' is the bottom plate hanging shaft, 6 is the pawl rod, 7 is the pawl, 8, 8' is the handle, 9, 9' is the lower end of the handle, 10 is the handle attachment part, 11.11' is the interlocking rod, 12 is the claw opening/closing board, 13
