[0035] For further information, see Figure 3 As shown, in this embodiment, the compression mechanism 2 includes a cylinder 21, a guide column 22, a pressure plate unit 23 and the pressure sensor 24; the cylinder 21 is vertically downwardly arranged on the support frame 1; the guide column 22 is vertically downwardly arranged around the cylinder 21, and the guide column 22 passes through the support frame 1 through a linear bearing 25; the pressure plate unit 23 is arranged at the front end of the output shaft of the cylinder 21, and the bottom end of the guide column 22 is fixed on the pressure plate unit 23. When in use, the pressure plate unit 23 can be driven by the cylinder 21 to float up and down, thereby compressing the garbage in the garbage bin; the pressure sensor 24 is arranged in the pressure plate unit 23. In this embodiment, continue to refer to Figure 3 As shown, two groups of guide posts 22 are provided. Of course, the above arrangement is only one implementation mode and is not intended to limit the scope of the present application. When the arrangement is implemented, more groups may be provided, for example, four groups.

[0036] For further information, see Figure 3 As shown, the compression mechanism 2 also includes an air pressure regulating valve 26, which is installed on the support frame 1; when installed, the air pressure regulating valve 26 is connected in series in the pipeline between the cylinder 21 and the air supply device, and the air pressure regulating valve 26 is used to control the output pressure of the cylinder 21 while ensuring the stable operation of the cylinder 21.

[0037] For further information, see Figure 6-9 As shown, the pressure plate unit 23 includes a fixed plate 231 and a movable plate 232 located below the fixed plate 231, the fixed plate 231 and the movable plate 232 are connected by a limiting bolt 233, and a return spring 234 is sleeved on the limiting bolt 233 between the fixed plate 231 and the movable plate 232; during installation, the fixed plate 231 is arranged at the front end of the output shaft of the cylinder 21, and the bottom end of the guide column 22 is fixed on the fixed plate 231, and the pressure sensor 24 is arranged on the fixed plate 231. The movable plate 232 is between the fixed plate 231 and the movable plate 232; when the garbage is compressed, the movable plate 232 is pressed upward and tends to move toward the fixed plate 231, thereby generating a force on the pressure sensor 24, thereby realizing monitoring of the downward pressure during the garbage compression process; after the garbage is compressed, the movable plate 232 tends to move in the opposite direction of the fixed plate 231 under the reaction force of the reset spring 234, thereby eliminating the force of the movable plate 232 on the pressure sensor 24. In order to prevent the pressure sensor 24 from moving between the fixed plate 231 and the movable plate 232, the fixed plate 231 is provided with a mounting groove 2311 for mounting the pressure sensor 24.

[0038] In this embodiment, see Figure 6 and Figure 8 As shown, in order to prevent garbage from entering between the fixed plate 231 and the movable plate 232 during the garbage compression process, causing the pressing machine to be everywhere, or affecting the monitoring result of the pressure sensor 24, a circle of baffles 235 are provided around the fixed plate 231 and the movable plate 232, and the lower end surface of the fixed plate 231 is sealed with the upper end surface of the baffle 235, and the upper half of the movable plate 232 extends into the baffle 235.

[0039] For further information, see Figure 4 and Fig.10 As shown, four groups of positioning pins 32 are arranged on the lower end surface of the positioning plate 3. Of course, the above arrangement is only one implementation mode and is not intended to limit the scope of the present application. When implementing the arrangement, other numbers of groups may also be arranged, but it should be noted that there shall be no less than two groups. Positioning holes 12 adapted to the positioning pins 32 are provided on the support frame 1. Through the cooperation between the positioning pins 32 and the positioning holes 12, the positioning plate 3 and the support frame 1 can be detachably connected, and the positioning plate 3 can be quickly replaced when compressing garbage in garbage bins of different specifications and models.

[0040] For further information, see Figure 5 As shown, the positioning groove 31 includes a body limiting groove 311 for limiting the lower end of the trash can body and a wheel limiting groove 312 for limiting the wheels of the trash can; and in this embodiment, the wheel limiting groove 312 corresponds to the wheels of the trash can one by one.

[0041] For further information, see Figure 2 As shown, the control system includes an electric control box 5 and a control panel 6; the electric control box 5 is fixed to the lower end of the support frame 1, and the control panel 6 is fixed to the upper end of the support frame 1 through a folding support seat.

[0042] The working principle of the utility model is as follows:

[0043] When it is necessary to compress the garbage in the trash can, first open the protective door 4, replace the positioning plate 3 with the corresponding positioning groove 31 into the supporting frame 1 according to the specifications of the trash can, and adjust the air pressure regulating valve 26 to the corresponding pressure and set the pressure value of the pressure sensor 24 through the control panel 6; then place the trash can filled with garbage into the chamber 11, at this time, the trash can body is restricted in the body limiting groove 311, and the trash can wheels are restricted in the wheel limiting groove 312; then start the compression mechanism 2 through the control panel 6, at this time, the pressure plate unit 23 is driven by the cylinder 21 to move downward to compress the garbage in the trash can, and when the pressure sensor 24 reaches the set pressure value, the cylinder 21 drives the pressure plate unit 23 to reset to the initial position; the compression work is completed.

[0044] It should be noted that the air pressure regulating valve 26 controls the output pressure of the air cylinder 21 to be slightly greater than the pressure value set by the pressure sensor 24, so as to ensure that when the garbage in the trash can is compressed, the pressure sensor 24 is given priority to control, so as to ensure automatic compression and resetting during the compression process; and the air pressure regulating valve 26 not only ensures the stable operation of the cylinder 21, but also prevents the pressure sensor 24 or the control system from malfunctioning, thereby avoiding excessive pressure under the pressing machine and damaging the trash can, thus playing a double guarantee role.

[0045] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
