On the rear surface (left surface) of the pressing plate 2a of the pressing body 2, a pair of pin receivers 6 penetrating in the vertical direction through pin holes 6a facing each other with a space therebetween are fixed by welding. 7 is a welding part.
The pressing body 2 is given a pressing force in the front direction from the operation mechanism 4 disposed rearward via the pin receiver 6. The pressing body 2 compresses the can K into a plate shape between the pressing body 2 and the inner wall 1d of the pressing processing chamber 1a located at the opposite position.

  The drive source 3 is constituted by a drive motor in the example shown in FIG. The drive motor 3 is provided in a casing 8 installed on the processing case 1. The driving force of the drive motor 3 is transmitted to the operating mechanism 4 via a speed reduction mechanism (not shown) disposed in the casing 8. Reference numeral 9 denotes a power terminal box.

The operating mechanism 4 is disposed in the storage chamber 1b as shown in FIGS. 1 and 2, and is engaged with a driving gear 10 that can be rotated by a driving force from the driving motor 3, and this driving gear. The rotating gear 12, an operating arm 14 connected to the rotating gear via a movable pin 15, and a support pin 17 for connecting the pressing body 2 to the operating arm are provided.
The drive gear 10 is attached to the drive shaft 11, and the rotation gear 12 is attached to the rotation shaft 13. The drive gear 10 is rotatable about the drive shaft 11 and the rotary gear 12 is rotatable about the rotation shaft 13 in opposite directions. The drive force from the drive motor 3 is transmitted to the drive shaft 11 via the speed reduction mechanism.
As shown in FIGS. 1 and 3, the actuating arm 14 has a movable pin 15 formed of a bolt inserted into one end (left end) of the operating arm 14 from the lower side toward the upper side. 16 is a washer. Further, the other end (right end) of the operating arm 14 is provided with a pin hole 14b through which the support pin 17 passes. 18 is a washer.
The operating arm 14 can rotate about the movable pin 15 and can rotate about the support pin 17.

Here, the relationship between the operating arm 14, the rotating gear 12, and the pressing body 2 will be described with reference to FIGS.
The movable pin 15 of the operating arm 14 is screwed into the insertion screw hole 12 a of the rotary gear 12. The working arm 14 is secured between the rotating gear 12 by a washer 16 and can be smoothly rotated around a movable pin.

For example, when the rotation gear 12 rotates in the arrow direction (counterclockwise direction) in FIG. Since it is connected to the rotating gear, it moves in the rotating direction of this rotating gear, and along with this movement, the operating arm moves (moves forward) toward the pressing chamber 1a while rotating around the movable pin. Accordingly, the pressing body 2 is pressed forward via the pin receiver 6, and the pressing body advances for this purpose (see FIGS. 4 and 5). When the rotation angle of the rotary gear 12 exceeds a predetermined angle (for example, 180 °), the movable pin 15 gradually moves in a direction to return to the initial position (the position in FIG. 1), so that the operating arm 14 is pressed via the movable pin. The body 2 is pulled rearward to release the pressing force of the pressing body (see FIG. 6).
The operating arm 14 moves back and forth according to the rotation angle of the rotary gear 12. Through this back-and-forth movement, the pressing body 2 reciprocates to release the can K or release it.

A method of using the can crusher M1 will be described by taking as an example a case of crushing a discarded empty can.
First, the opening / closing lid 5 of the pressing chamber 1a of the processing case 1 is opened, the can K is inserted into the pressing chamber from the insertion port 1a1, and then the opening / closing lid is closed (FIG. 1).
Next, the drive motor 3 is driven. Then, since the driving force of the drive motor 3 is transmitted to the drive shaft 11 and rotationally driven, the drive gear 10 also rotates around the drive shaft. With this rotation, the rotating gear 12 rotates about the rotating shaft 13. When the drive gear 10 rotates in the clockwise direction (arrow direction) in FIG. 2, for example, the rotary gear 12 rotates in the counterclockwise direction (arrow direction) in FIG. As a result of this rotation, the movable pin 15 is moved a predetermined distance counterclockwise around the rotation shaft 13 as shown in FIG. It moves to the front side (right side in FIG. 4) and pushes the pressing body 2 connected to the other end forward. At that time, the operating arm 14 pushes the pressing body 2 while rotating around the support pin 17 on the other end side.
In this way, the operating arm 14 gradually pushes the pressing body 2 forward in conjunction with the rotation of the rotating gear 12, and the pressing body 2 pushes the can K in the pressing processing chamber 1a by this pressing, and the inner wall 1d of the pressing processing chamber 1d. Press towards and compress.
The operating arm 14 shown in FIG. 4 shows a position when the rotary gear 12 is rotated 90 ° counterclockwise from the initial position (position shown in FIG. 2).
Eventually, when the movable pin 15 reaches a position (position shown in FIG. 5) rotated by 180 ° from the initial position in conjunction with the rotation of the rotary gear 12, the operating arm 14 has the inner wall 1d of the pressing process chamber 1a. The can K is pressed into a plate shape, and as a result, the plate-shaped processing can K1 is dropped and discharged downward from the discharge port 1c.
When the rotating gear 12 further rotates counterclockwise, the movable pin 15 returns from the position shown in FIG. 5 to the initial position through the position shown in FIG. 6. At this time, the operating arm 14 is movable as the movable pin moves. When the pin 2 is moved rearward by the pin, the pressing body 2 is pulled backward by this movement, and the operating arm finally returns to the original position, the pressing body also returns to the original position, and preparation for the next pressing process is performed. to go into.
As described above, when the rotary gear 12 rotates 360 °, the operating arm 14 reciprocates in the left-right direction in FIG. 2 via the movable pin 15, and by this reciprocation, the pressing body 2 also approaches the inner wall 1d and reciprocates. Exercise is performed, and the can K is pressed and released by the pressing body.
