[0045] Please refer to Figure 1 and Figure 2 , Figure 1The figure shows a schematic structural diagram of the outer shell of a packing machine in an embodiment of the present application. A packing machine outer shell 1000 provided in an embodiment of the present application includes: a housing 1100, a sound insulation component 1200, and a first sound insulation cover plate 1300. The housing 1100 has a receiving cavity 1110 for accommodating an object. One side of the housing 1100 along a first direction is provided with an access opening 1120, and the access opening 1120 communicates with the receiving cavity 1110. The sound insulation component 1200 is located inside the housing 1100 to isolate the noise generated by the object in the receiving cavity 1110. The sound insulation component 1200 includes two first sound insulation members 1210 and two second sound insulation members 1220. The two first sound insulation members 1210 are correspondingly arranged on both sides of the receiving cavity 1110 along a second direction, and the two second sound insulation members 1220 are correspondingly arranged on both sides of the receiving cavity 1110 along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other pairwise. The first sound insulation cover plate 1300 covers the access opening 1120.

[0046] In the packing machine outer shell 1000 in this embodiment, when the packing machine (not shown) inside the housing 1100 makes noise, the two first sound insulation members 1210 located on both sides of the receiving cavity 1110 along the second direction absorb and isolate the noise generated by the packing machine in the second direction. The two second sound insulation members 1220 located on both sides of the receiving cavity along the third direction absorb and isolate the noise generated by the packing machine in the third direction. The first sound insulation cover plate 1300 covering the access opening 1120 absorbs the noise generated by the packing machine in the first direction. In summary, by setting the first sound insulation cover plate 1300 to cover the access opening 1120 and using the first sound insulation cover plate 1300 in cooperation with the first sound insulation members 1210 and the second sound insulation members 1220, the receiving cavity 1110 inside the housing 1100 is wrapped with multiple sound insulation devices, and the noise generated by the packing machine in the receiving cavity 1110 can be isolated in multiple directions, thereby improving the noise reduction effect of the packing machine outer shell 1000 and meeting the production requirements.

[0047] Please refer to Figure 1 And Figure 2 In some embodiments, two guiding hole assemblies 1130 are provided on one side of the packing machine outer shell 1000 along the third direction. The two guiding hole assemblies 1130 are arranged at intervals along the second direction. Each guiding hole assembly 1130 includes a guiding through hole 1131. Each guiding through hole 1131 extends along the third direction and communicates with the receiving cavity 1110. The two guiding hole assemblies 1130 are correspondingly arranged with the two first sound insulation members 1210. A first sound insulation member 1210 is inserted into the guiding through hole 1131 of each guiding hole assembly 1130. Each first sound insulation member 1210 is slidably connected to the corresponding guiding through hole 1131 and can slide relative to the corresponding guiding through hole 1131 along the third direction to enter or leave the housing 1100 along the third direction.

[0048] In the present embodiment, each first sound insulation member 1210 passes through the corresponding guide through hole 1131 and extends into the accommodating cavity 1110 of the shell 1100, so as to isolate and absorb the noise generated by the baler in the accommodating cavity 1110 in the second direction. Since each first sound insulation member 1210 is slidably connected with the corresponding guide through hole 1131, and the resistance of sliding friction to movement is small, when the staff disassembles, replaces, and cleans the first sound insulation member 1210, they can use fewer people to apply a smaller force in the third direction, so that the first sound insulation member 1210 slides relative to the guide through hole 1131, and then the corresponding first sound insulation member 1210 is pulled out of the shell 1100. The disassembly and installation of the first sound insulation member 1210 and the shell 1100 are simple to operate, saving time and effort.

[0049] In some embodiments, two slide rails 1140 are provided in the shell 1100, and the two slide rails 1140 are arranged in a one-to-one correspondence with the two first sound insulation members 1210. Each slide rail 1140 extends along the third direction. Each slide rail 1140 is arranged on the side of the corresponding first sound insulation member 1210 close to the shell 1100 along the second direction, and is slidably connected to the corresponding first sound insulation member 1210. By providing the slide rails 1140, when the staff applies external force to the first sound insulation member 1210, the first sound insulation member 1210 always moves along the third direction relative to the corresponding guide through hole 1131.

[0050] In some embodiments, the first sound insulation member 1210 is made of sound insulation cotton (not shown). As a sound insulation material, the sound insulation cotton can reduce the propagation and reflection of sound waves, reduce the noise level in the surrounding environment, and effectively absorb and reduce the noise generated when the baler is running. When the sound insulation cotton absorbs too much noise and its own temperature exceeds a preset value, the staff can remove the sound insulation cotton from the housing 1100 along the third direction through the guide hole 1131 to reduce the temperature of the baler housing 1000 and extend the service life of the baler housing 1000.

[0051] See also Figure 2 In some embodiments, each guide hole assembly 1130 includes two guide through holes 1131, and the two guide through holes 1131 are arranged one-to-one on both sides of the shell 1100 along the third direction, and the axes of the two guide through holes 1131 are collinear, and the two ends of each first sound insulation member 1210 along the third direction are passed through the two guide through holes 1131 of the corresponding guide hole assembly 1130 one-to-one.

[0052] In this embodiment, by passing the two ends of each first sound insulation member 1210 along the third direction through the two guiding through holes 1131 of the corresponding guiding hole assembly 1130 in a one-to-one correspondence, on the one hand, the support of the housing 1100 for the first sound insulation member 1210 can be strengthened; on the other hand, it is convenient for the staff to apply an external force to the first sound insulation member 1210 on any side of the housing 1100 along the third direction, so as to remove it from the housing 1100 along the third direction or install it into the housing 1100.

[0053] In some embodiments, the packing machine housing 1000 includes a decibel detector (not shown), and the decibel detector is located inside the housing 1100 to detect the decibels of the noise generated by the packing machine inside the housing 1100 in various directions. The staff can, according to the detection data of the decibel detector, grasp the noise level inside the packing machine housing 1000 in real time, and then it is convenient to replace the sound insulation component 1200 with better sound insulation effect when the detection data is greater than the target value, so as to control the noise inside the packing machine housing 1000 within the target value.

[0054] In some embodiments, the packing machine housing 1000 includes a central processing unit (not shown) and a display (not shown). The central processing unit and the display are both arranged outside the packing machine housing 1000, and the decibel detector and the display are both communicatively connected to the central processing unit.
