However, there may be positions on the production line where it is necessary to change the conveying direction or turn, and for this, a quick-change device for the corner of the cigarette packet conveyor belt is required. The quick-change device for the corner of the cigarette packet conveyor belt can quickly change the direction at the corner of the cigarette packet conveyor belt or the roller, enabling the cigarette packet to pass through the corner smoothly and continue to be conveyed along the new direction, thus avoiding problems such as accumulation, jamming, or dropping of cigarette packets at the corner, and ensuring the continuous conveyance of cigarette packets and the normal operation of the production line.

[0003] Currently, the Chinese utility model patent with the publication number CN203601904U discloses a quick-change device for the corner of a conveyor belt of a packaging machine, which includes a base. The base is provided with a base horizontal shaft hole and a base vertical shaft hole; a horizontal pulley is arranged on a horizontally rotating shaft; a vertical pulley is arranged on a vertically rotating shaft; a quick-change cover plate, and a cover plate horizontal shaft hole is provided on the side surface of the quick-change cover plate, and a cover plate vertical shaft hole is provided on the bottom surface; one end of the horizontal rotating shaft is fixed in the base horizontal shaft hole, and the other end is fixed in the cover plate horizontal shaft hole, and one end of the vertical rotating shaft is fixed in the base vertical shaft hole, and the other end is fixed in the cover plate vertical shaft hole. However, this utility model has the following problems: 1. Both its horizontal shaft and vertical shaft are fixed to the quick-change cover plate with adjusting bolts, the pulley rotates on the shaft, and there is no bearing designed between the pulley and the shaft, resulting in rapid wear between the pulley and the shaft; 2.

[0114] The specific installation steps are as follows:

[0115] Installation steps of the first conveying assembly 2:

[0116] 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. Subsequently, the first positioning pin 24 is connected to the first pulley pin hole and the first connecting shaft positioning pin hole.

Subsequently, the operator installs the first internal snap ring 253 in the first internal snap ring slot inside the first bearing sleeve 251. In this way, the first bearing 252, the first bearing sleeve 251 and the first internal snap ring 253 are installed into the first rotating assembly 25.

[0118] Immediately afterwards, the operator sleeved the first rotating assembly 25 on the first connecting shaft 21, and then installed the first connecting pins 41 into the corresponding connecting pin holes on the base 1 respectively.

[0119] Then, the operator installs the first quick-release plate 3.

[0120] Finally, after the operator passes two first locking parts 42 through the corresponding first quick-release plate connection holes, the first quick-release plate 3 is tightened on the corresponding side plate of the base 1. Subsequently, the operator installs the first fastening screw 254 through the corresponding connection hole into the end thread hole of the first connecting shaft 21 to prevent axial movement of the first rotating assembly 25 during the operation of the equipment.

[0121] Installation steps of the second conveying assembly 5:

[0122] The installation steps of the second conveying assembly 5 are the same as those of the first conveying assembly 2, which will not be elaborated here. During installation, the first connecting shaft 21 in the accommodating bin 11 is set perpendicular to the first connecting shaft 51, and the first bevel gear 22 is meshed with the second bevel gear 52. Thus, the assembly work of the present invention is completed.

[0123] Installation steps of the present invention on the conveyor:

[0124] First, the operator installs the longitudinal conveying belt 8 on the first pulley 23, installs the transverse conveying 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 27 and the second support 29 of the conveyor 10 through fastening screws, that is, the installation work of the corner quick-change device on the conveyor 10 is completed.

[0126] First, install a bearing in the installation opening at the bevel gear end of the first connecting shaft 51 corresponding to the base 1. There are internal circlip grooves on the base 1 corresponding to both ends of the bearing. After installing the bearing, install the corresponding internal circlip to ensure that the bearing cannot axially move in the installation opening. Pass the first connecting shaft 51 through the bearing hole of the base 1, install a 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;

[0127] Then, install a bearing in the installation opening at the bevel gear end of the first connecting shaft 21 on the base 1. There are internal circlip grooves on the base 1 corresponding to both ends of the bearing. Install two internal circlips at both ends of the bearing respectively, and then install a key on the side of the bevel gear end of the first connecting shaft 21. First, place the first bevel gear 22 into the accommodation bin 11 to mesh with the second bevel gear 52, and then pass the end of the first connecting shaft 21 with the key through the bearing and align it with the keyway of the first bevel gear 22, install it, and tighten the nut at the end of the first connecting shaft 21, and it is installed. First, pass the bevel gear end of the first connecting shaft 51 through the bearing and then install the key, and then install the second bevel gear 52.

[0128] The specific usage steps are as follows:

[0129] During use, first, the cigarette pack 10a produced by the upstream equipment reaches the second conveying assembly 5 through the horizontal conveying belt 9. Then, driven by the second pulley of the second conveying assembly 5, the cigarette pack 10a is conveyed to the longitudinal conveying belt 8 connected to the first conveying assembly 2 through the connected horizontal conveying belt 9. Finally, driven by the longitudinal conveying belt 8, the cigarette pack 10a is conveyed to the downstream equipment; during the use process, the corner quick-change device can adjust the direction through the connected horizontal conveying belt 9 and longitudinal conveying belt 8, so that the cigarette pack 10a can smoothly change the direction and continue to move forward, avoiding problems such as accumulation, jamming or dropping of the cigarette pack 10a at the corner, ensuring the continuous conveying of the cigarette pack 10a and the normal operation of the production line.

[0130] Embodiment 1

[0133] 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. Subsequently, the first positioning pin 24 is connected to the new first pulley pin hole and the first connecting shaft positioning pin hole;

[0134] Immediately afterwards, the operator installs the new assembly component of the first rotating assembly 25 on the first connecting shaft 21;

[0135] 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 connecting 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;

[0136] Finally, after the operator passes two first locking parts 42 through the corresponding first quick-release plate connection holes, the first quick-release plate 3 is tightened on the base 1. Subsequently, the operator installs the first fastening screw part 254 in the threaded hole at the end of the first connecting shaft 21, and the quick replacement of the first pulley 23 and the first bearing 252 is completed.

[0137] During the above usage process, 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 Embodiment 1 and will not be elaborated here.

Since the transverse conveying belt 9 needs to bypass the second pulley of the second conveying assembly 5 and pass through the gap between the second pulley and the base 1, when replacing, the operator needs to remove the second locking part of the second locking assembly 7, remove the second quick-release plate 6, then put 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 part to complete the replacement of the transverse conveying belt 9;

[0141] When the operator replaces the longitudinal conveying belt 8, since 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, when replacing the longitudinal conveying belt 8, onlyFigure 1 It can be sleeved on the first pulley 23 as shown.

[0142] Embodiment 3

[0143] The other structures are the same as those in Embodiment 1 and Embodiment 2. The only difference is that when one end of the second quick-release plate 6 is a stepped structure and the base 1 is provided with a connection structure adapted to the stepped structure:

[0144] When the longitudinal conveyor belt 8 and the transverse conveyor belt 9 are worn or broken and need to be replaced: First, when the operator replaces the transverse conveyor belt 9, the operator only needs to remove the second locking assembly 7 or remove the second connecting pin of the second locking assembly 7 and loosen the second locking member of the second locking assembly 7. Then, the operator rotates the second quick-release plate 6 clockwise by 180 degrees. Immediately afterwards, the transverse conveyor belt 9 is sleeved into the gap between the second pulley and the base 1. Finally, the operator rotates the second quick-release plate 6 counterclockwise by 180 degrees, installs the second connecting pin and tightens the second locking member to complete the replacement of the transverse conveyor belt 9;

[0145] When the operator replaces the longitudinal conveyor belt 8, since the longitudinal conveyor 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, when replacing the longitudinal conveyor belt 8, only as Figure 1 shown, it can be sleeved on the first pulley 23.

[0146] When replacing the transverse conveyor belt 9 as described above, it is not necessary to disassemble the second quick-release plate 6, and the replacement of the transverse conveyor belt 9 can be completed faster.
