Can compression equipment

A can compression equipment, comprising:

• a frame;
• a pressing block arranged at an end of an interior of the frame, wherein an accommodating space is defined between the pressing block and a bottom of the frame and configured for accommodating a can to-be-compressed;
• and
• a driving device connected to the pressing block and configured for driving the pressing block to move forward or backward along a lengthwise direction of the frame to thereby change a size of the accommodating space;
• wherein the driving device comprises:
• a drive cylinder mounted at the end of the frame, and an end of a piston rod of the drive cylinder is arranged in the interior of the frame and fixedly connected to the pressing block;
• and
• a control valve connected to the drive cylinder and configured for controlling the piston rod of the drive cylinder to extend or retract;
• wherein the can compression equipment further comprises:
• an automatic feeding device arranged on an opened end of the frame, wherein the automatic feeding device is configured for placing another can to-be-compressed located outside of the frame into the interior of the frame through the opened end of the frame when the driving device completes a compression on the can to-be-compressed located in the interior of the frame;
• wherein the automatic feeding device comprises:
• a transportation passage arranged above the opened end of the frame and configured for accommodating a plurality of cans to-be-compressed arranged juxtaposedly, and an outlet end of the transportation passage is aligned with the opened end of the frame;
• and
• a blocking apparatus arranged between the opened end of the frame and the outlet end of the transportation passage and configured for limiting number of the plurality of cans to-be-compressed falling into the interior of the frame to be 1 each time;
• wherein the blocking apparatus comprises:
• a pre-extended cylinder and a pre-retracted cylinder oppositely arranged below the transportation passage, a rod cavity of the pre-extended cylinder and a rodless cavity of the pre-retracted cylinder are both communicated with a rodless cavity of the drive cylinder of the driving device.
