[0002] Among tobacco packaging machines, the ZB416 hard box packaging machine is a common packaging equipment. As a high-speed packaging unit specially used for cigarette pack production, its designed production capacity is 600 packs / minute. The nozzle needs to suck 600 times per minute, so it is a consumable part and needs to be replaced frequently.

[0003] However, the nozzle on the extractor will wear out or be damaged during long-term use and needs to be replaced regularly. The traditional way to replace the nozzle requires disassembling the entire device, removing the nozzle device from the extractor, and then squeezing the nozzle into the hole of the front suction plate. Since the bottom of the nozzle is relatively thick, it is not easy to squeeze into the narrow hole. This process can also easily cause the new nozzle to be damaged. The damaged nozzle does not meet the use requirements. The replacement operation is cumbersome, the maintenance efficiency is low, and it is easy to cause damage to the equipment.

[0004] Therefore, designing a device that can quickly replace suction nozzles is of great significance for improving equipment maintenance efficiency and reducing maintenance costs, and is a technical difficulty that technical personnel in this field urgently need to solve. Utility Model Content

[0039] Please refer to Figures 1 to 3 , the technical scheme of the utility model is specifically described as a device for quickly replacing and installing a suction nozzle 3 on an extractor of a ZB416 hard box packaging machine, comprising: a first support 1, a second support 2, a suction nozzle 3, and a rear support 4;

[0040] Compared with the fixed suction nozzle 3 mounting seat in the prior art, the suction nozzle 3 with high toughness needs to be deformed by a large external force for press-fitting; in the present technical solution, the first support 1 and the second support 2 are combined by a detachable connection, a split assembly design is adopted, and a cavity 5 for accommodating the suction nozzle 3 is formed between them, so that the installation process of the suction nozzle 3 is simplified;

[0041] like Figure 1 , Figure 3 as well as Figure 4 The back of the suction nozzle 3 is also provided with the rear support 4, which is connected to the first support 1 and the second support 2 through a detachable connection, and the rear support 4 is also provided with an air hole 6 connected to the suction nozzle 3, and negative pressure is generated through the air hole 6, so that the suction nozzle 3 generates suction to suck and release the cigarette pack;

[0042] As a split-type nozzle 3 mounting seat in the present technical solution, its important innovation lies in that an opening is provided at the top of the first support 1, and the width of the opening is smaller than the volume of the nozzle 3, so that the nozzle 3 can be snap-fitted into the cavity 5 in the first support 1 and abutted and fixed by the second support 2; specifically, Figure 5 As shown, when the suction nozzle 3 needs to be pressed into the first support 1, compared with the fixed mounting seat in the prior art, an opening is provided in the first support 1, which can make it more convenient for the suction nozzle 3 to be pressed into the cavity 5 in the first support 1.

[0043] As a preferred example, Figure 5 As shown, in this embodiment, the air hole 6 is provided on the back of the rear support 4, and its function is to connect the negative pressure air pipe to provide negative pressure for the suction nozzle 3. By switching the negative pressure air pipe on and off, the air hole 6 and thus the suction force of the suction nozzle 3 are controlled, thereby switching the suction and release of the cigarette box during the production process.

[0044] Further, such as Figure 5 As shown, in this embodiment, the air hole 6 is arranged at the center of the rear support 4. The air hole 6 arranged at the center can enable the suction nozzle 3 to provide suction to the cigarette box more evenly, thereby ensuring the reliability of the suction process.

[0045] Preferably, compared with the fixed mounting seat in the prior art, the present application scheme uses the first support 1 and the second support 2 as split bodies, and an opening is provided on the first support 1, so that the suction nozzle 3 can be conveniently pressed into the first support 1; therefore, in order to facilitate the press-fitting of the suction nozzle 3, as Figures 1 to 5As shown, in this embodiment, the opening of the first support 1 is set as an inclined surface, and the inclined surface of the first support 1 is set to expand from the center of the opening toward the second support 2. Specifically, the opening gradually expands from the inside to the outside; through such a structural setting, the suction nozzle 3 can be easily pressed and installed into the first support 1.

[0046] Better, such as Figure 1 and Figure 5 As shown, in the present embodiment, the specific method of the detachable connection between the first support 1 and the second support 2 is a threaded connection through bolts, and a threaded hole is set through the contact assembly surface of the first support 1 and the second support 2, so that the bolt can penetrate the contact assembly surface of the first support 1 and the second support 2 to fix and lock them.

[0047] As a preferred example, Figure 1 and Figure 5 As shown, in the present embodiment, in order to allow the device for quickly replacing and installing the suction nozzle 3 provided by the present application scheme to be stably set on the extractor, a mounting hole 7 is further provided on the side of the first support 1 for detachable connection with the extractor; specifically, the mounting holes 7 are stacked and arranged on both sides of the first support 1, and are generally connected to the extractor by bolts.

[0048] As a preferred example, Figure 5 As shown, in order to facilitate the suction nozzle 3 to be easily pressed into the first support 1, the side of the suction nozzle 3 is symmetrically provided with an arc structure. Specifically in this embodiment, the cross-sectional shape of the suction nozzle 3 is an elliptical structure.

[0049] Further, such as Figure 5 As shown, the suction nozzle 3 as a whole is forward from the rear support 4, and according to the specific functional layout, the specific parts are sequentially distinguished as: a plane abutment part 8, a middle support part 9, and an arc-shaped suction part 10;

[0050] The plane abutting portion 8 is used to abut against the rear support 4, and its width is greater than the size of the cavity 5 of the first support 1, and is used to be clamped with the first support 1 and the back of the second support 2;

[0051] The intermediate support portion 9 is used as the main support portion of the nozzle 3, and its outer surface is engaged with the first support 1 and the second support 2 for support;

[0052] The arc-shaped suction part 10 is the main action part of the suction nozzle 3 for providing negative pressure suction. By providing the arc-shaped suction part 10, the suction is carried out as close to the surface of the cigarette box as possible during contact with the cigarette box.

[0053] Furthermore, the widths of the first support 1 and the second support 2 are set corresponding to the middle support portion 9. Figure 1 , Figures 3 to 5 As shown, in order to ensure that the suction nozzle 3 fits tightly with the first support 1 and the second support 2, the width of the intermediate support portion 9 is equal to the width of the first support 1 and the second support 2 to ensure that there is no gap.

[0054] Furthermore, the suction nozzle 3 is an integrally formed rubber molded part, which has the characteristics of high flexibility and high strength, ensuring that it can be pressed into the first support 1.

[0055] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
