Description

Technical Field

[0001] The present application relates to cardboard processing, and in particular to a square board feeding structure. Background Art

[0002] Cardboard, a sturdy material made from layers of tightly bonded paper, has seen its applications expand rapidly over time, encompassing advertising displays, product packaging, architectural model making, jigsaw puzzles, and more. Precise cutting of square cardboard is a key step in its production.

[0003] A square cardboard cutting device currently available on the market consists of a stable base, a rotating cutting wheel mounted on top of the base, and a power system that drives the cutting wheel. This system is supported by a support arm on the base. The power system specifically includes an electric cylinder vertically fixed to the support arm and a motor directly connected to the cutting wheel. The electric cylinder drives the motor and cutting wheel in a vertical reciprocating motion, achieving precise cutting of the cardboard placed below the base.

[0004] However, in practice, the feeding process for square cardboard is relatively inefficient. Traditionally, workers manually load the entire stack onto a platform, then manually separate and select the top cardboard for processing. This process is not only labor-intensive but also requires frequent manual handling and selection, leaving room for improvement. Utility Model Content

[0005] The purpose of this application is to provide a square board feeding structure to solve the problem of low square cardboard feeding efficiency in the above-mentioned related technologies.

[0006] The square plate feeding structure provided in this application adopts the following technical solution:

[0007] A square plate feeding structure includes a base and a pedestal, the upper side surface of the pedestal is lower than the upper surface height of the pedestal, a vertical plate is fixed on the pedestal, a lifting plate for stacking cardboards is slidably provided on the vertical side surface of the vertical plate, and a power source for driving the lifting plate to slide up and down is fixed; a support arm is fixed on the pedestal, a pneumatic suction cup is slidably provided on the support arm, and a driving source for driving the pneumatic suction cup to slide is fixed, and the pneumatic suction cup can slide back and forth between above the lifting plate and above the pedestal.

[0008] By adopting the above technical solution, when clamping the cardboard to the upper surface of the base, due to the coordinated setting of the lifting plate, power source, pneumatic suction cup and driving source, the staff will pre-stack the cardboard on the upper surface of the lifting plate, and then move the pneumatic suction cup to the top of the lifting plate through the driving source to clamp the uppermost cardboard, and then move the pneumatic suction cup and the clamped cardboard to the top of the base through the driving source, and then the pneumatic suction cup stops clamping the cardboard, thereby realizing the feeding of the cardboard; when clamping again, the power source drives the lifting plate to move upward as a whole by the thickness of a cardboard, and this cycle is repeated, thereby realizing automatic feeding of the cardboard and improving the feeding efficiency of the cardboard.

[0009] Optionally, a crossbeam extending to above the base is fixed on the support arm, and the driving source includes a support block slidingly arranged on the crossbeam, and a linear motor fixed on the crossbeam to drive the support block to slide back and forth. A driving cylinder is fixed on the support block in the vertical direction, and the telescopic rod of the driving cylinder faces downward and is fixedly connected to the pneumatic suction cup.

[0010] By adopting the above technical solution, due to the combined arrangement of the crossbeam, linear motor, support block and drive cylinder, the pneumatic suction cup can move back and forth in the horizontal and vertical directions, ensuring the smooth progress of the cardboard feeding process.

[0011] Optionally, a vertical cylinder located above the lifting plate is fixed on the crossbeam, the telescopic rod of the vertical cylinder faces downward, and a lifting suction cup is fixed on the end of the telescopic rod of the vertical cylinder.

[0012] By adopting the above technical solution, when clamping the cardboard, due to the installation arrangement of the lifting suction cup, the lifting suction cup can be used to lift one side edge of the uppermost cardboard to a certain height, and then the pneumatic suction cup can be used to suck the middle part of the cardboard tightly, and then the lifting suction cup stops sucking, and it is clamped to the base only by the pneumatic suction cup; thereby, the height of the uppermost cardboard when it is sucked by the pneumatic suction cup is increased, which facilitates the pneumatic suction cup to suck the cardboard tightly.

[0013] Optionally, a protruding plate is fixed on the side of the lifting plate close to the vertical plate, and the power source includes a power motor fixed on the side of the vertical plate in the vertical direction, and a power screw fixed coaxially with the output shaft of the power motor. An adjusting screw hole for the power screw to be screwed in is provided on the protruding plate, and the side of the protruding plate away from the lifting plate abuts against the side of the vertical plate.

[0014] By adopting the above technical solution, after the lifting plate is installed, the protruding plate is away from the side of the lifting plate and abuts against the side of the vertical plate. Due to the coordinated setting of the power motor and the power screw, when the power motor is started, it can drive the power screw to rotate synchronously, thereby driving the lifting plate to move up and down.

[0015] Optionally, a guide plate is fixedly provided on the side of the lifting plate close to the vertical plate, and a guide groove for the guide plate to be inserted and slide is opened on the side of the vertical plate in the vertical direction.

[0016] By adopting the above technical solution, due to the coordinated arrangement of the guide plate and the guide slot, when the lifting plate slides up and down, the guide plate slides up and down synchronously in the guide slot, thereby improving the stability of the lifting plate during the sliding process.

[0017] Optionally, a guide rod is fixedly provided inside the guide slot on the vertical plate, and a guide through hole for the guide rod to pass through is opened on the guide plate.

[0018] By adopting the above technical solution, due to the setting of the guide rod, the guide plate is further limited in sliding by the guide rod during the sliding process in the guide groove, thereby further enhancing the stability of the lifting plate during the up and down sliding process.

[0019] Optionally, an extension plate is hinged on the side of the lifting plate away from the vertical plate, and the extension plate can be flipped downward and detachably connected to the bottom side of the lifting plate; a receiving rod is hinged on the side of the lifting plate facing the base, and the rotating surface of the receiving rod is parallel to the bottom side of the lifting plate; when the extension plate is rotated to a position flush with the side surface of the lifting plate, the end of the receiving rod can be rotated to the bottom side of the extension plate for support

[0020] By adopting the above technical solution, due to the arrangement of the extension plate and the receiving rod, when the size of the cardboard being fed is large, the extension plate can be rotated upward to a position flush with the side surface of the lifting plate, and then the receiving rod can be rotated so that the end of the receiving rod is rotated to the bottom side of the extension plate for support; thereby improving the application range of the feeding structure.

[0021] Optionally, an elastic positioning piece is fixed on the receiving rod, and a positioning slot for inserting the elastic positioning piece is provided on the extension plate.

[0022] By adopting the above technical solution, when one end of the receiving rod moves to the bottom side of the extension plate to support it, the elastic positioning piece on the receiving rod is inserted into the positioning slot on the bottom side of the extension plate, thereby improving the installation stability of the extension plate in this state.

[0024] 1. When clamping the cardboard to the upper surface of the base, the staff will first place the cardboard stack on the upper surface of the lifting plate, and then use the driving source to move the pneumatic suction cup to the top of the lifting plate to clamp the uppermost cardboard. The driving source will then move the pneumatic suction cup and the clamped cardboard to the top of the base, and then the pneumatic suction cup will stop clamping the cardboard to achieve the feeding of the cardboard. When clamping again, the power source will drive the lifting plate to move upward as a whole by the thickness of a cardboard, and this cycle will be repeated. BRIEF DESCRIPTION OF THE DRAWINGS
