[0106] Before using the novel cigarette pack conveyor belt corner quick-change device of the above-mentioned design structure, the already manufactured device needs to be installed as a spare.

[0107] The specific installation steps are:

[0108] Installation steps of the first conveying component 2:

[0109] First, the operator installs the first pulley 23 on the first connecting shaft 21, and makes the first pulley pin hole on the first pulley 23 correspond to the first connecting shaft positioning pin hole on the first connecting shaft 21, and then connects the first positioning pin 24 to the first pulley pin hole and the first connecting shaft positioning pin hole;

[0111] Next, the operator sleeves the first rotating assembly 25 onto the first connecting shaft 21, and then installs the first connecting pins 41 into the corresponding connecting pin holes of the base 1;

[0112] Then, the operator installs the first quick release plate 3. When installing the first quick release plate 3, it should be noted that the corresponding first quick release plate connecting hole should correspond to the first connecting pin 41, and the first quick release plate connecting port on the first quick release plate 3 should correspond to the first rotating assembly 25;

[0113] Finally, the operator passes the two first locking members 42 through the corresponding first quick-release plate connecting holes, and then tightens the first quick-release plate 3 to the corresponding side plate of the base 1; then, the operator passes the first fastening screw 254 through the corresponding connecting hole and installs it in the end threaded hole of the first connecting shaft 21 to prevent the first rotating component 25 from axial movement when the equipment is running.

[0114] Installation steps of the second conveying assembly 5:

[0115] The installation steps of the second conveying assembly 5 are the same as those of the first conveying assembly 2, and will not be repeated here. During installation, the first connecting shaft 21 and the second connecting shaft 51 in the accommodating bin 11 are arranged perpendicularly, and the first bevel gear 22 and the second bevel gear 52 are meshed and connected, thus completing the assembly work of the utility model;

[0116] The installation steps of the utility model on the conveyor:

[0117] First, the operator installs the longitudinal conveyor belt 8 on the first pulley 23, and installs the transverse conveyor belt 9 on the second pulley of the second conveying assembly 5. Finally, the operator fixes the corner quick-change device on the first support body 27 and the second support body 29 of the conveyor 10 by tightening the screws, thereby completing the installation of the corner quick-change device on the conveyor 10.

[0118] Installation process of the bevel gear parts of the second connecting shaft 51 and the first connecting shaft 21:

[0119] First, install the bearing in the installation hole of the bevel gear end corresponding to the second connecting shaft 51 on the base 1. There are internal retaining ring grooves on the base 1 corresponding to both ends of the bearing. After installing the bearing, install the corresponding internal retaining ring to ensure that the bearing cannot move axially in the installation hole. Pass the second connecting shaft 51 through the bearing hole of the base 1, install the key in the keyway on the side of the shaft end, align the keyway on the second bevel gear 52 with the key on the shaft, install the second bevel gear 52, and then lock the nut at the end of the second bevel gear 52;

[0120] Then, a bearing is installed in the installation opening of the bevel gear end of the first connecting shaft 21 on the base 1. There are internal retaining ring grooves on the base 1 corresponding to the two ends of the bearing. Two internal retaining rings are installed at the two ends of the bearing respectively. Then, the key is installed on the side of the bevel gear end of the first connecting shaft 21. First, the first bevel gear 22 is placed in the accommodating chamber 11 and meshed with the second bevel gear 52. Then, the end of the first connecting shaft 21 with the key is passed through the bearing and opposite to the keyway of the first bevel gear 22. Install it, and tighten the nut at the end of the first connecting shaft 21. First, the bevel gear end of the second connecting shaft 51 is passed through the bearing and the key is installed, and then the second bevel gear 52 is installed.

[0121] The specific steps are:

[0122] When in use, first, the cigarette packs 10a produced by the upstream equipment pass through the transverse conveyor belt 9 to reach the second conveying component 5, and then, driven by the second pulley of the second conveying component 5, the cigarette packs 10a are conveyed to the longitudinal conveyor belt 8 connected to the first conveying component 2 through the transverse conveyor belt 9 connected thereto, and finally, driven by the longitudinal conveyor belt 8, the cigarette packs 10a are conveyed to the downstream equipment; during use, the corner quick-change device can adjust the direction through the transverse conveyor belt 9 and the longitudinal conveyor belt 8 connected thereto, so that the cigarette packs 10a can change direction smoothly and continue to move forward, avoiding the occurrence of problems such as accumulation, jamming or falling of the cigarette packs 10a at the corners, thereby ensuring the continuous transportation of the cigarette packs 10a and the normal operation of the production line.

[0123] Example 1

[0124] When the first pulley 23 and the first bearing 252 are damaged and need to be replaced, during disassembly: the operator first disassembles the first locking member 42, the first quick release plate 3, the first fastening screw 254, and the assembly components of the first rotating assembly 25 in order, then removes the first inner retaining spring 253, removes the first bearing 252, removes the first positioning pin 24, and finally removes the first pulley 23;

[0125] During installation: the operator first replaces the new first bearing 252, then installs the new first bearing 252 in the first bearing sleeve 251, and then installs the first inner retaining spring 253 to form a new first rotating assembly 25;

[0126] Then, the operator replaces the new first pulley 23, installs the new first pulley 23 on the first connecting shaft 21, and makes the first pulley pin hole on the first pulley 23 correspond to the first connecting shaft positioning pin hole on the first connecting shaft 21, and then connects the first positioning pin 24 to the new first pulley pin hole and the first connecting shaft positioning pin hole;

[0127] Next, the operator installs the new first rotating assembly 25 assembly components on the first connecting shaft 21;

[0128] Then, the operator installs the first quick release plate 3. When installing the first quick release plate 3, it should be noted that the first quick release plate connection hole should correspond to the first connection pin 41, and the first quick release plate connection port on the first quick release plate 3 should correspond to the first rotating assembly 25.

[0129] Finally, the operator passes the two first locking members 42 through the corresponding first quick-release plate connecting holes and tightens the first quick-release plate 3 on the base 1. Subsequently, the operator installs the first fastening screw 254 in the end threaded hole of the first connecting shaft 21, thereby completing the quick replacement of the first pulley 23 and the first bearing 252.

[0130] Example 2

[0131] When the longitudinal conveying belt 8 and the transverse conveying belt 9 are worn or broken and need to be replaced: first, the operator replaces the transverse conveying belt 9, because the transverse conveying belt 9 needs to bypass the second pulley of the second conveying assembly 5, and the transverse conveying belt 9 needs to pass through the gap between the second pulley and the base 1. When replacing, the operator needs to disassemble the second locking member of the second locking assembly 7, remove the second quick release plate 6, and then insert the transverse conveying belt 9 into the gap between the second pulley and the base 1. Finally, the operator installs the second quick release plate 6 and tightens the second locking member to complete the replacement of the transverse conveying belt 9.

[0132] When the operator replaces the longitudinal conveying belt 8, because the longitudinal conveying belt 8 is wound around the first pulley 23 and does not pass through the gap between the first pulley 23 and the base 1, the longitudinal conveying belt 8 only needs to be replaced as follows: Figure 1 Just put it on the first pulley 23 as shown.

[0133] Example 3

[0134] During the above use, if the second pulley and the second bearing of the second conveying assembly 5 also need to be replaced, the replacement steps are the same as those in Example 1 and will not be repeated here.

[0135] Finally, it should be noted that the above is only a preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
