Description

Technical Field

[0001] This utility model relates to the field of cardboard box production and processing technology, and in particular to a die-cutting device for cardboard box production. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and various specifications and models are available. Three-layer and five-layer cardboard boxes are commonly used, while seven-layer boxes are less common. Each layer consists of linerboard, corrugated paper, core paper, and facing paper. Linerboard and facing paper are made of kraft paper or corrugated cardboard, while the core paper is made of corrugated paper. The colors and textures of different types of paper vary, and the paper produced by different manufacturers also differs. In the cardboard box production process, die-cutting is one of the key steps, used to cut cardboard into specific shapes for folding into cardboard boxes. Existing die-cutting equipment has the following problems:

[0003] 1. When clamping and fixing cardboard, manual adjustment or simple clamping mechanisms are usually used, which makes it difficult to ensure the precise positioning of the cardboard, resulting in cutting deviations and affecting the quality of the finished product.

[0004] 2. Existing die-cutting equipment usually uses fixed die-cutting molds. Fixed die-cutting equipment is difficult to adapt to cardboard of different sizes. Adjusting the clamping position is cumbersome and affects production efficiency. Utility Model Content

Fixed columns 2 are fixedly connected to the rear outer surfaces of the two support blocks. Two clamping plates are provided on the front outer surfaces of the fixed columns 2.

[0007] A support frame is fixedly connected to the upper rear surface of the workbench, and a fixed column three is fixedly connected to the lower top surface of the support frame. An electric telescopic rod is provided on the lower surface of the fixed column three, and a cutter is fixedly connected to the output end of the electric telescopic rod.

[0008] According to the die-cutting device for carton production, a first drive motor is fixedly connected to the upper outer surface of the fixed column on the right side. A first threaded rod is fixedly connected to the output end of the first drive motor. A first threaded block is threadedly connected to the outer surface of the first threaded rod. A first moving block is fixedly connected to the left outer surface of the first threaded block. The first moving block is fixedly connected to the right outer surface of the support block on the right side. The first drive motor drives the first threaded rod to rotate, thereby causing the first threaded block to move downward, further causing the first moving block to move downward, and causing the support block to be adjusted. In this way, the height of the two clamping plates can be adjusted according to the actual height of the cardboard, so as to satisfy the clamping and limiting of cardboard of different heights and improve the practicality of the device.

A bidirectional threaded rod is fixedly connected to the output end of the second drive motor. A second threaded block is threadedly connected to the outer surface of the bidirectional threaded rod. A second moving block is fixedly connected to the front outer surface of the second threaded block. The second moving block is fixedly connected to the rear outer surface of the clamping plate. The bidirectional threaded rod is driven to rotate by the second drive motor, thereby driving the second threaded block to move. Then, the second moving block slides linearly in the moving groove. According to the actual width of the cardboard, the position of the two clamping plates is adjusted to achieve symmetrical clamping of the cardboard and avoid the offset problem caused by unilateral force.

[0011] According to the die-cutting device for carton production, a movable groove is provided on the front outer surface of the second fixed column, and the second movable block slides on the inner surface of the movable groove. The movable groove serves to limit the movement of the second movable block and ensure the stable adjustment of the clamping plate.

[0012] According to the die-cutting device for carton production, a third drive motor is fixedly connected to the outer right side of the fixed column three. A lead screw is fixedly connected to the output end of the third drive motor. A third moving block is threadedly connected to the outer surface of the lead screw. An installation block is fixedly connected to the lower side of the third moving block. The electric telescopic rod is fixedly installed on the lower surface of the installation block. The lead screw is driven to rotate by the third drive motor, thereby driving the third moving block to move and adjusting the position of the installation block, thereby realizing the longitudinal position adjustment of the cutter.

[0013] According to the die-cutting device for carton production, a limiting member is fixedly connected to the top lower surface of the support frame, and the movable end of the limiting member is fixedly connected to the upper surface of the cutter. The limiting member provides guiding support for the up-and-down movement of the cutter, ensuring the stability of the cutting process.

[0029] Working principle: In use, by starting the first drive motor 21, the first threaded rod 22 is driven to rotate, causing the first threaded block 23 to move longitudinally along the first threaded rod 22, which drives the support block 25 to adjust its position, thereby driving the two clamping plates 35 to adjust their height. After adjusting to the appropriate height, the second drive motor 31 is started to drive the bidirectional threaded rod 32 to rotate, causing the two second threaded blocks 33 to move towards each other, thereby driving the clamping plates 35 to clamp the cardboard, preventing displacement during die-cutting, ensuring cutting accuracy, and simultaneously satisfying the clamping and positioning of cardboard of different sizes, reducing the time for workers to change clamping parts. When cutting the cardboard, by starting the third drive motor 51, the lead screw 52 is driven to rotate, causing the third moving block 53 to move along the lead screw 52, ​​adjusting the longitudinal position of the electric telescopic rod 6 and the cutter 7, and then the electric telescopic rod 6 drives the cutter 7 to punch the cardboard, thereby achieving precise positioning of the cutter 7 according to the die-cutting requirements, adapting to the die-cutting of different specifications of cartons.
