As such, the main body 100 may be installed to be movable in various structures.

In the illustrated embodiment, the guide part 150 is fixedly installed on the main body 100, and the movable shaft bearing housing 140 moves horizontally along the guide part 151 provided in the guide part 150. Illustrative of the possible combination. On the other hand, the main body 100 is provided with a through-hole formed along the moving direction so that the rotating shaft 132 of the driven compression drum 130 can be moved.

On one side of the movable shaft bearing housing 140, the movable shaft bearing housing is movable to maintain the appropriate pressing force while the driven compression drum 130 is movable according to the load generated during the compression of the inputs introduced into the main body 100. An elastic support means for elastically supporting 140 is provided.

In the illustrated embodiment the elastic support means is made of a mechanical spring support structure. That is, the movable rod 160 extending in the horizontal direction is connected to the movable shaft bearing housing 140, and the movable rod 160 is a guide hole of the support part 153 provided on one side of the guide part 150. It is installed to be movable through the 154. The movable rod 160 is provided with a first spring support member 161, and the movable rod 160 is positioned between the first spring support member 161 and the support part 153 of the guide part 150. The pressure spring 170 is installed outside the. The pressure spring 170 elastically supports the movable shaft bearing housing 140 in the forward direction through the first spring support member 161 so that the driven compression drum 130 drives the compression drum when the can is compressed. The spacing can be varied while applying appropriate pressure in the (120) direction.

In addition, a second spring support member 163 is provided at an opposite side of the first spring support member 161 of the movable rod 160, and the second spring support member 163 and the guide part 150 are provided.

The shock absorbing spring 180 elastically supports the movable shaft bearing housing 140 in the retracting direction through the second spring support member 163, so that the driven compression drum 130 drives the compressed compression drum when the compressed can is discharged. Fast forward to 120 to prevent collisions.

Referring to the operation of the can pressing apparatus of the present invention configured as described above are as follows.

When the motor 110 is driven, the rotational power of the motor 110 is transmitted to the driving compression drum 120 through the belt 113, and the rotational force of the driving compression drum 120 is gear teeth 121 and 131. It is transmitted to the driven compression drum 130 through the two compression drums 120, 130 are rotated in the opposite direction to each other.

In this state, the can is introduced into the main body 100 through the hopper 101, and the introduced can is bitten by the gear teeth 121 and 131 on both sides, and is driven between the driving compression drum 120 and the driven compression drum 130. After being forced in, it is compressed flat while passing between the gear teeth 121 and 131 on both sides, and is discharged to the lower portion of the main body 100.

At this time, the driven compression drum 130 is installed to be movable back and forth along the guide portion 150, and is elastically supported by the pressure spring 170, the driving compression drum according to the load generated when the can is pressed ( 120 and the interval between the driven compression drum 130 may be automatically adjusted.

Accordingly, when a hard foreign matter is mixed in the inserted candle, the driven compression drum 130 is moved in a direction away from the driving compression drum 120, and the compression drums 120 and 130 due to excessive load or mechanical shock, and the like. No damage to the drive and the support occurs. Therefore, the service life of the device is extended, there is an advantage that the cost and manpower required for maintenance is reduced.

Therefore, the productivity of the can crimping process is improved, the installation cost of the device is reduced, and the maintenance is also easy.

In particular, when a bottle of high strength is injected, the compressive force transmitted to the compression drum is much greater than the elastic force of the pressure spring installed on the movable rod, so that the driven compression drum has a larger retraction movement distance, so that the bottle is not crushed and discharged naturally to the outlet side. Can be.

On the other hand, in the above-described embodiment illustrates that the mechanical spring is used as the elastic support means of the movable shaft bearing housing 140, the present invention is not limited to this, the elastic support means is a fluid using hydraulic or pneumatic It may be made of a cylinder structure. That is, the movable shaft bearing housing 140 and the guide portion 150 or one side of the main body 100 is connected to the fluid cylinder is stretched in accordance with the pressure installed in the drive compression drum 120 according to the load generated when the can is pressed The position of the driven compression drum 130 relative to may be configured to vary.

In addition, the movement guide means of the movable shaft bearing housing 140 is not limited by the guide unit 150 illustrated in the embodiment, the guide for supporting the movable shaft bearing housing 140 to enable a linear movement. Bars, guide shoes, guide rails and the like can be made of various conventional structures.

Figure 6 shows another embodiment of the can crimping apparatus according to the present invention, it is configured to adjust the installation interval of the drive compression drum 120 and the driven compression drum (130).

Male threads 167 and 168 in opposite directions are formed at ends of the coupling holes to correspond to the respective female threads 192 and 193 of the coupling hole 191. Although not shown, the first rod 160a and the second rod 160b coupled to the coupling hole 191 may be penetrated in both directions of the connector 190 so as to be more firmly fixed. It is preferable that a fixing bolt is pressed in close contact with the outer circumferential surfaces of the first rod 160a and the second rod 160b. More preferably, a fixing groove or a fixing hole into which the fixing bolt is inserted may be formed in the first rod 160a and the second rod 160b.

In such a configuration, when the connector 190 is rotated, the first rod 160a is moved forward or backward with respect to the second rod 160b, so that the installation position of the movable shaft bearing housing 140 is changed. By precisely adjusting the installation interval of the drive compression drum 120 and the driven compression drum 130 according to the specifications or strength, there is an advantage that the compression ratio of the can can be further improved without burdening the device.

Meanwhile, the first rod 160a, the second rod 160b, and the connector 190 are illustrated as position adjusting means of the movable shaft bearing housing 140, and the position adjusting means is movable in addition to the screw coupling method.
