Description

Technical Field

[0001] The present application relates to the technical field of cardboard processing, and in particular to a waste cardboard shredding device. Background Art

[0002] Corrugated cardboard can be processed into corrugated boxes, the most widely used packaging product. Due to its superior performance and good processing properties, corrugated boxes have become the mainstay of transportation packaging. In addition to protecting products and facilitating storage and transportation, they also enhance and promote products. Furthermore, corrugated boxes are recyclable and green products. After recycling, the waste cardboard is typically shredded to facilitate subsequent processing.

[0003] However, in actual applications, due to its flat shape, after being put into the shredding equipment, the shredding cutter and the cardboard are prone to slippage, which will cause the corrugated cardboard to accumulate in the shredding equipment and cannot be shredded in time. If necessary, the equipment needs to be stopped and the cardboard needs to be cleaned out manually, which is time-consuming and labor-intensive.

[0004] Therefore, those skilled in the art provide a waste cardboard shredding device to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the present application provides a waste cardboard shredding device.

[0007] A waste cardboard crushing device comprises a chassis, a feeding port is provided on the top of the chassis, a shield is installed on the feeding port, and a crushing component and a pushing component are arranged in the chassis;

[0008] The crushing component includes a crushing roller installed horizontally in the chassis, and a plurality of raised blocks are arranged on the surface of the crushing roller along a spiral array, and the horizontal spacing between the plurality of raised blocks is set to be the same;

[0009] The pushing component includes an extrusion block slidably installed in the chassis. The side of the extrusion block facing the crushing roller is processed into an arc surface, and a plurality of grabbing tooth blocks are arranged in the arc surface.

[0010] Preferably, an outwardly convex rib is further provided on the top of the extrusion block, the rib extends laterally to cover the arcuate surface, and a hydraulic push rod is also installed on the back of the extrusion block.

[0023] like Figure 1-3 As shown, the present application discloses a waste cardboard shredding device, comprising a chassis 1, a feeding port 11 being provided on the top of the chassis 1, a baffle 12 being installed on the feeding port 11, a discharge port 13 being further provided on one side of the chassis 1, a cover plate 14 being hingedly installed in the discharge port 13, and an electric-controlled telescopic rod 15 being installed at the bottom of the cover plate 14, the bottom end of which is installed on the chassis 1, a shredding component 2 being provided in the chassis 1, the shredding component 2 comprising a shredding roller 201 being transversely installed in the chassis 1, a plurality of raised blocks 202 being provided on the surface of the shredding roller 201 along a spiral array, the horizontal spacing between the plurality of raised blocks 202 being the same, and when the shredding roller 201 rotates, the raised blocks 202 can grab the cardboard and tear it, thereby facilitating the shredding of the cardboard and making the processing more convenient;

[0024] like Figure 3 As shown, a pushing component 3 is further provided in the chassis 1, and the pushing component 3 includes an extrusion block 301 slidably installed in the chassis 1, and the side of the extrusion block 301 facing the crushing roller 201 is processed into an arc surface, and a plurality of grabbing tooth blocks 302 are provided in the arc surface, and a convex rib 303 is further provided on the top of the extrusion block 301, and the rib 303 extends laterally to cover the arc surface, and a hydraulic push rod 304 is further installed on the back of the extrusion block 301, and in order to prevent the cardboard from sticking to the bottom wall or slipping between the cardboard and the crushing roller 201, with the cooperation of the hydraulic push rod 304, the extrusion block 301 can be pushed to slide toward the crushing roller 201, and the cardboard can be pushed toward the crushing roller 201 and squeezed tightly against the crushing roller 201, at this time, the raised block 202 on the crushing roller 201 can grab the cardboard for processing;

[0025] Example 2

[0026] like Figure 2As shown, on the basis of Example 1, a plurality of cutting blades 203 are further provided on the side of the crushing roller 201 away from the extrusion block 301, and the plurality of cutting blades 203 are all arranged at positions between adjacent raised blocks 202. The plurality of cutting blades 203 are mounted on the same drive shaft 204, and the central axis of the crushing roller 201 and the outer end of the drive shaft 204 are both installed with drive motors 205, and the two drive motors 205 are arranged in opposite directions. With the cooperation of the cutting blades 203, the cardboard torn from the raised block 202 can be quickly shredded, which facilitates shortening the crushing processing time. The cutting blades 203 are arranged at positions between adjacent raised blocks 202, which can avoid collision between the cutting blades 203 and the raised block 202, which is safer.

[0027] Furthermore, in order to avoid the phenomenon that cardboard is stuck between adjacent cutting blades 203, a blocking roller 206 is provided on the side of the cutting blade 203 away from the crushing roller 201, and a plurality of baffles 207 are installed on the blocking roller 206. The baffles 207 are set at the position between adjacent cutting blades 203, and torsion springs 208 are provided between the two ends of the blocking roller 206 and the chassis 1. The baffles 207 set on the blocking roller 206 extend to the position between adjacent cutting blades 203, which can block the cardboard stuck here and stop the cardboard. In addition, the two ends of the blocking roller 206 are installed in the chassis 1 through the torsion springs 208. When the cardboard collides with the baffles 207, the torsion springs 208 can offset part of the impact force, thereby avoiding damage to the cutting blade 203.

[0030] The implementation principle of a waste cardboard shredding device in the embodiment of the present application is as follows:

[0031] During use, waste cardboard is fed into the chassis 1 from the feeding port 11. With the cooperation of the driving motor 205, the crushing roller 201 and the driving shaft 204 can be driven to rotate. When the crushing roller 201 rotates, the raised block 202 can grab the cardboard and tear it, making it convenient to tear the cardboard into pieces. In order to prevent the cardboard from sticking to the bottom wall or slipping between the cardboard and the crushing roller 201, the hydraulic push rod 304 can be used to push the squeezing block 301 to slide toward the crushing roller 201, so that the cardboard can be pushed toward the crushing roller 201 and squeezed tightly against the crushing roller 201. At this time, the raised block 202 on the crushing roller 201 can grab the cardboard for processing.

[0032] Moreover, with the cooperation of the cutting blade 203, the cardboard torn from the raised block 202 can be quickly shredded, which is convenient for shortening the shredding processing time. The cutting blade 203 is set between adjacent raised blocks 202 to avoid collision between the cutting blade 203 and the raised block 202, which is safer.
