Description

Technical Field

[0001] This utility model relates to the field of corrugated paper processing technology, and in particular to a trimming device for corrugated cardboard processing. Background Technology

[0002] Corrugated cardboard, also known as corrugated paperboard, is made of at least one layer of corrugated paper and one layer of linerboard bonded together. It has good elasticity and extensibility and is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods. It is made by pulping straw pulp and waste paper to make a base paperboard similar to yellow cardboard, which is then mechanically processed to be rolled into a corrugated shape. After the corrugated cardboard is shaped, it needs to be trimmed with an edge trimming device.

[0003] However, the existing trimming devices have the following problems: after the cardboard is trimmed, there is usually waste material left on the worktable. After working for a long time, the waste material can easily lift the cardboard placed later, which will cause the device to trim the cardboard unevenly and affect the trimming quality. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the prior art, after the cardboard is trimmed, there is usually waste material left on the worktable. After a long period of work, the waste material can easily lift the cardboard placed later, causing uneven trimming of the cardboard and affecting the trimming quality. Therefore, an trimming device for corrugated cardboard processing is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A trimming device for corrugated cardboard processing includes a workbench with arc-shaped corners on all four sides. Support columns are fixedly connected to the four bottom corners of the workbench. A U-shaped top frame is fixedly connected to both sides of the top of the workbench. Support rods for stability are fixedly installed on the front and rear sides of the top frame. A lifting mechanism for fixing the corrugated cardboard is installed on the top frame. A trimming mechanism for trimming the corrugated cardboard is installed on the lifting mechanism. A pushing mechanism for cleaning up waste material is also installed on the lifting mechanism.

[0007] In one possible design, the lifting mechanism includes a first electric telescopic rod, two side plates, two positioning rods, and a pressure plate. The fixed end of the first electric telescopic rod is fixedly mounted on the top frame. The telescopic end of the first electric telescopic rod slides through the center of the top of the top frame and is fixedly connected to a first plate. The bottom of the first plate is fixedly connected to the top of the pressure plate. The two sides of the pressure plate are fixedly connected to the sides of the two side plates respectively. The top ends of the two positioning rods are fixedly connected to the two sides of the inner top wall of the same top frame respectively. The bottom ends of the two positioning rods are fixedly connected to the top of the same worktable. The two side plates are slidably sleeved on the two positioning rods respectively.

[0008] In one possible design, the trimming mechanism includes a connecting plate, a lead screw, a second motor, a rectangular hole, a connecting block, a first motor, and a trimming disc. The bottom of the connecting plate is fixedly connected to the top of the pressure plate. The rectangular hole is located on the connecting plate, and a rectangular groove is formed on the top of the connecting plate. The two ends of the lead screw are rotatably connected to the inner walls of the two ends of the same rectangular groove via bearings. One side of the second motor is fixedly connected to one side of the connecting plate via bolts. The output shaft of the second motor rotatably passes through one side of the connecting plate and extends into the interior of the rectangular groove. The output shaft of the second motor is fixedly connected to one end of the lead screw. The connecting block is threaded onto the lead screw and slidably connected to the top of the connecting plate. The first motor is fixedly mounted on the connecting block via bolts. The output shaft of the first motor is fixedly located at the center of one side of the trimming disc. A thin blade for trimming is provided on the outer side of the trimming disc, and the bottom of the trimming disc passes through the rectangular hole and is flush with the bottom of the pressure plate.

[0009] In one possible design, the pushing mechanism includes a second electric telescopic rod, a notch, a push plate, and two insert rods. The notch is disposed on the push plate. The fixed end of the second electric telescopic rod is fixedly connected to the inner wall of the notch. The telescopic end of the second electric telescopic rod is fixedly connected to the front side of the push plate. One end of each of the two insert rods is fixedly connected to the two front sides of the same push plate. The two rear sides of the pressure plate are provided with slots that are adapted to the insert rods. The other ends of the two insert rods are slidably inserted into the two slots to position the movement of the push plate.

[0010] In one possible design, lighting lamps are fixedly connected to both sides of the bottom of the connecting plate to facilitate observation of the trimming process.

[0011] In one possible design, a storage box is placed at the bottom rear of the workbench to facilitate the storage of waste materials generated from corrugated paper trimming, and the top of the storage box is set to be open.

[0012] In this application, during use, the corrugated cardboard to be trimmed is placed on the workbench and aligned with the markings on the workbench. The controller activates the first electric telescopic rod, whose telescopic end drives the first plate and the pressure plate downwards. Simultaneously, the two side plates slide on the two positioning rods to ensure the stability of the pressure plate's movement until the pressure plate presses the corrugated cardboard firmly onto the workbench. Then, the controller activates the first and second motors. The output shaft of the first motor drives the trimming disc to rotate, and the output shaft of the second motor drives the lead screw to rotate. The lead screw drives the connecting block to slide on the top of the connecting plate. The connecting block drives the first motor and the trimming disc to move, thereby trimming the corrugated cardboard fixed by the pressure plate. After trimming is completed, the controller activates the second electric telescopic rod, whose telescopic end drives the push plate to move backwards. The push plate pushes the waste material on the workbench into the storage box, reducing the impact of trimming waste on the subsequent placement and trimming of the corrugated cardboard. The two insert rods slide in the slots to ensure the stability of the push plate's movement.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, the lifting mechanism can accurately press the corrugated cardboard onto the worktable, providing a stable and fixed foundation for the trimming operation, improving the accuracy of trimming. The trimming disc in the trimming mechanism performs efficient and precise trimming of the corrugated cardboard. The design of the pushing mechanism can conveniently and quickly push the waste generated during trimming into the storage box, reducing the impact of waste on subsequent operations and improving work efficiency. At the same time, the lighting provided provides illumination for the trimming process, making it convenient for operators to observe the trimming situation and helping to promptly identify and deal with problems that arise during the trimming process.
