Technical Field

[0001] This utility model relates to the field of die-cutting equipment technology, and in particular to an automatic feeding device for cardboard die-cutting. Background Technology

[0002] There are many types of cardboard, among which corrugated cardboard has high mechanical strength and can withstand collisions and drops during handling. Therefore, corrugated cardboard is widely used in the production of cartons. Cartons are made from a single sheet of corrugated cardboard through a series of processes including die-cutting, scoring, trimming, folding, and stapling. The die-cutting of cardboard with a cardboard die-cutting machine is a crucial step that determines whether the carton can be formed in the end. The front of the cardboard die-cutting machine has an upper and lower conveyor belt that rotate in opposite directions to feed the cardboard, while the rear has a cutting wheel and a pad wheel that rotate in opposite directions to cut the cardboard. The die-cutting efficiency of the cardboard die-cutting machine is relatively fast, and manual feeding often cannot keep up with the machine's operation. Workers stack the cardboard on the platform in front of the cardboard die-cutting machine's feed port, letting the cardboard wait for the upper and lower conveyor belts to pull it in, similar to a printer pulling out paper.

[0003] The automatic die-cutting feeding device has the following defects: the cardboard moves during feeding, causing a certain offset, which leads to die-cutting position deviation and affects the quality of subsequent die-cutting processes. To address this problem, an automatic cardboard die-cutting feeding device is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic feeding device for cardboard die-cutting, which aims to improve the problem in the prior art where the cardboard moves during feeding, causing a certain offset and resulting in die-cutting position deviation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic feeding device for cardboard die-cutting, comprising a die-cutting platform, a frame, and a die-cutting device. The frame is fixedly connected to the bottom outer wall of the die-cutting platform, and the die-cutting device is fixedly connected to the front outer wall of the die-cutting platform. A leveling mechanism and an auxiliary mechanism are provided on the die-cutting platform. The leveling mechanism includes a slide groove, which is formed on the top inner wall of the die-cutting platform. A threaded rod is rotatably connected to the left inner wall of the slide groove via a bearing. An adjusting disc is fixedly connected to the left end of the threaded rod.

A lever is slidably connected to the top inner wall of the adjusting disc. A limit rod is fixedly connected to the front outer wall of the lever, and a compression spring is fixedly connected to the rear outer wall of the lever.

[0006] As a further description of the above technical solution: the auxiliary mechanism includes a bracket, which is fixedly connected to the front outer wall of the die-cutting processing platform. A movable plate is slidably connected to the top inner wall of the bracket. An insert plate is fixedly connected to the right outer wall of the movable plate. A telescopic spring is fixedly connected to the left outer wall of the movable plate. An adjusting frame is slidably connected to the top inner wall of the bracket.

[0007] As a further description of the above technical solution: a conveyor belt is fixedly connected to the top outer wall of the die-cutting processing platform, and a material unloading rack is fixedly connected to the right outer wall of the die-cutting processing platform.

[0008] As a further description of the above technical solution: the arc-shaped guide frame is slidably connected to the top outer wall of the die-cutting processing platform, and there are a number of rollers, which are rotatably connected to the bottom inner wall of the arc-shaped guide frame.

[0009] As a further description of the above technical solution: the top outer wall of the scale is fixedly connected with a display coating, the front and rear outer walls of the lever are fixedly connected with frosted pads, the limiting rod is snapped into the rear inner wall of the die-cutting platform, and the end of the compression spring away from the lever is fixedly connected to the rear inner wall of the adjustment disc.

[0010] As a further description of the above technical solution: silicone pads are fixedly connected to the outer walls of the left and right sides of the movable plate, and the insert plate is snapped into the inner wall of the left side of the adjustment frame.

[0011] As a further description of the above technical solution: a steel sleeve is fixedly connected to the outer side wall of the insert plate, and the end of the telescopic spring away from the movable plate is fixedly connected to the inner left side wall of the bracket.

[0012] This utility model has the following beneficial effects: In this utility model, through the coordinated design of the straightening mechanism and the auxiliary mechanism, on the one hand, the arc-shaped guide frame in the straightening mechanism can cooperate with the transmission of the threaded rod and the threaded sleeve to realize the spacing adjustment. Combined with the scale, it can accurately adapt to cardboard of different widths. At the same time, the rollers at the bottom of the arc-shaped guide frame can reduce the resistance of cardboard conveying and avoid surface wear, effectively preventing the cardboard from deviating during the conveying process.

[0013] In this invention, the height of the transverse wheel can be adjusted by the adjusting frame, maintaining a suitable distance between the transverse wheel and the conveyor belt for the cardboard thickness. This prevents cardboard stacking during feeding and ensures that cardboard of different specifications can be stably and orderly conveyed along the set track, providing a reliable guarantee for precise processing by subsequent die-cutting equipment and reducing processing defects caused by conveying deviations. 3. In this utility model, the locking and unlocking of the adjustment frame can be quickly completed by the movable plate and the telescopic spring, reducing the difficulty of adjusting the height of the horizontal wheel. In terms of component durability, the steel sleeve on the side of the insertion plate can enhance the structural strength and wear resistance of the insertion plate, and prevent the insertion plate from deforming or wearing due to repeated clamping. The silicone pads on both sides of the movable plate can reduce the frictional wear between the movable plate and the inner wall of the bracket, and extend the service life of the components. The overall design reduces the workload of the operator and the frequency of component replacement, thereby reducing the use and maintenance costs of the device and improving the overall operating cost-effectiveness of the equipment.
