The sensor measuring assembly 3 is directly arranged on the frame assembly 1, so that the sensor measuring assembly 3 is convenient to maintain, the maintenance cost is reduced, and the service life of a sensor cable is prolonged.
The density door assembly 5 includes an upper density door 501 and two side density doors 502, where the two side density doors 502 are vertically disposed and located on the left and right sides of the floor of the frame assembly 1, and the upper density door 501 is located above the space between the two side density doors 502. Specifically, the upper density door 501, the two side density doors 502 and the bottom plate of the frame assembly 1 enclose a chamber, and a square material bag is arranged in the chamber. The oil cylinder of the density gate extrudes three density gates to move inwards, so that the internal cavity is reduced, and the aim of increasing the density of the square material bag is fulfilled. The density of the material square bag can be controlled by controlling the oil pressure of the oil cylinder of the density gate. The control of the pressure of the density gate cylinder is regulated according to the data measured by the sensor measuring assembly 3.

In one specific example, the density control method is:
The method comprises the steps that a preset deformation amount is set in a controller, and the controller obtains the actual frame deformation amount of the frame upper beam 102 through a force sensor 302;
The controller compares the preset deformation with the actual frame deformation; if the actual frame deformation is larger than the preset deformation, reducing the pressure of the density gate cylinder, and thus adjusting the position of the density gate assembly 5, so that the difference between the actual frame deformation and the preset deformation is within an error range; if the actual frame deformation is smaller than the preset deformation, the pressure of the density door cylinder is increased, so that the position of the density door assembly 5 is adjusted, and the difference between the actual frame deformation and the preset deformation is within an error range.
