Description

Building drawing crushing apparatus

Technical Field

The invention relates to drawing smashing equipment, in particular to building drawing smashing equipment.

Background

The building drawing mainly expresses the shape and position relation of the building, reflects the forms and positions of roofs, doors, windows, balconies, awning, steps and the like, and is high in all parts in the vertical direction of the building. In construction, the basis of the building drawing is adopted. And the number of the building drawings is also different according to the complexity degree of the building body. The building is generally divided into a front elevation, a back elevation and a side elevation, can be divided into a south elevation, a north elevation, an east elevation and a west elevation according to the orientation of the building, and can be named as the name of the elevation according to the axis number, which is particularly suitable for the building with complex plane shape.

Just because the building drawings need to express many things, the building drawings tend to have larger paper sizes and a large number of paper sizes. After the construction is finished, other drawings except drawings which need to be kept are destroyed, so that the leakage of the drawing content is avoided. When the building drawing is crushed, a common paper crusher can be used, and effective paper crushing is performed. However, a typical shredder is designed for A4 paper size shredding, with the shredding port being the same size as the A4 paper size. Because the building drawing itself has the characteristics of large size and large number, when the common paper shredder pulverizes the building drawing, the drawing needs to be folded first and then is crashed when being plugged into a shredding port. However, after the construction drawing with larger size is folded into the size of A4, the thickness exceeds the gap diameter of the paper shredding opening, and the paper shredding opening cannot be plugged into the paper shredding opening for crushing. Therefore, in the actual crushing process, when the existing paper shredder is used for crushing, the drawing needs to be torn into small pieces firstly for smooth crushing, and then the drawing is folded into the size A4 for crushing, so that the paper crushing operation steps of staff are increased, and time and labor are wasted.

In view of the above, there is a need for a construction drawing comminution apparatus for comminuting construction drawings.
