Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, specifically to a waste paper shredding device for cardboard box processing. Background Technology

[0002] Cardboard boxes are one of the most widely used packaging products. They have advantages such as being lightweight and easy to fold. However, during the processing of cardboard boxes, some excess scraps are generated. These scraps can be recycled by crushing them.

[0003] Existing methods for recycling cardboard box scraps typically involve shredding them in a shredder. However, the scraps produced after shredding vary in size, making them difficult to package and collect. Furthermore, the collected scraps are quite large, taking up considerable space and hindering transportation. Therefore, we propose a waste paper shredding device for cardboard box processing. Utility Model Content

The slider is slidably connected to the inner cavity of the lifting groove. A connecting rod is fixedly connected between the inner sides of the slider, and the bottom of the connecting rod is fixedly connected to the inner side of the slider. A cutter is fixedly connected to the slitting box. Conveying rollers are rotatably connected between the front and rear side walls and the left and right sides of the inner cavity of the slitting box. The rear end of the conveying rollers passes through the slitting box and extends to the rear side of the slitting box. A first gear is fixedly connected to the rear end of the conveying rollers, and the first gear meshes and rotates. A feeding port is opened at the top of the slitting box. Water outlet pipes are embedded in the left and right side walls of the inner cavity of the feeding port. A circular cutter disc assembly is rotatably connected between the front and rear side walls and the left and right sides of the inner cavity of the slitting box, located below the conveying rollers. The rear end of the rotating shaft of the circular cutter disc assembly passes through the slitting box and extends to the rear side of the slitting box. A second gear is fixedly connected to the rear end of the rotating shaft of the circular cutter disc assembly, and the second gear meshes and rotates. Synchronous pulleys are fixedly connected to the rear sides of the first gear and the second gear, and a synchronous belt is rotatably connected between the synchronous pulleys.

[0007] Preferably, the workbench has an internal mounting hole, an electric push rod is fixedly connected to the inner cavity of the mounting hole, and a push plate is fixedly connected to the end of the electric push rod.

[0008] Preferably, a support frame is fixedly connected to the top right side of the workbench, a multi-stage telescopic electric hydraulic cylinder is fixedly connected to the inner side of the support frame, and a pressure plate is fixedly connected to the bottom end of the multi-stage telescopic electric hydraulic cylinder.

[0009] Preferably, a conveying device is provided on the left side of the bottom of the inner cavity of the workbench, and the conveying device includes a conveying motor, a rotating roller and a conveying steel belt.

[0010] Preferably, a variable frequency motor is fixedly connected to the front side wall of the slitting box, the power output shaft of the variable frequency motor passes through the slitting box and extends into the inner cavity of the slitting box, and the power output shaft of the variable frequency motor is fixedly connected to the left conveying roller.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This waste paper shredding device for cardboard box processing uses a variable frequency motor to drive the conveyor rollers to rotate. Under the meshing action of the first gear, the conveyor rollers rotate relative to each other to transport waste paper. At the same time, the synchronous belt drives the synchronous pulley to rotate. Under the meshing action of the second gear, the circular cutter head group rotates relative to each other to perform transverse cutting of waste paper into strips. The strips are then transported by a conveyor device. The rotating motor drives the camshaft to rotate. When the camshaft rotates, it drives multiple sets of cutters at the bottom of the connecting rod to move up and down alternately. The connecting rod moves within the lifting groove by a slider and is reset by a spring, thus achieving longitudinal cutting of waste paper strips into blocks. This allows for uniform shredding and cutting of waste paper, facilitating subsequent packaging and collection.

[0013] This waste paper shredding device for cardboard box processing involves filling the installation trough with water before shredding the waste paper. A conveying pump delivers water to the outlet pipe via a conveying pipeline. Sprayers on the outlet pipe wet the waste paper before shredding it. The shredded waste paper blocks are then conveyed to a filter plate in the installation trough. An electric hydraulic cylinder drives a pressure plate to descend, squeezing and dehydrating the wetted waste paper blocks, thus compressing and shaping them. An electric lifting rod then lifts the compressed paper blocks, and an electric push rod drives a push plate to push the paper blocks out. This process reduces the volume of the shredded waste paper after compression, making it less prone to scattering and facilitating subsequent transportation. Attached Figure Description

[0025] Example: Figures 1-7 As shown, this utility model provides a waste paper crushing device for cardboard box processing, which can uniformly crush and cut waste paper, making it easier for later packaging and collection. It can also compress the crushed waste paper to a smaller volume and make it less likely to scatter, facilitating later transportation. The device includes a workbench 100, a cutting box 200, and a slitting box 300.

[0026] Please see Figure 1 , Figure 2 and Figure 5 The workbench 100 has a mounting groove 110 on the bottom right side of its inner cavity.
