Referring to fig. 1, in an embodiment of the present application, a cigarette packet buffering structure 100 is provided, which includes a mounting base 110, a blowing head 120, and a buffering member 130. Blowhead 120 is used for circulating gas and comprises a first circulating section 121 and a second circulating section 122 which are communicated, and first circulating section 121 is installed on mounting base 110 and is used for being communicated with a gas source. The buffer 130 is sleeved on the second flow-through section 122 and has a buffering portion 131, and in the extending direction of the second flow-through section 122, the buffering portion 131 is disposed in a protruding manner compared with an end of the second flow-through section 122 departing from the first flow-through section 121.

The cigarette packet buffering structure 100 is mounted on the bearing member through the mounting seat 110, so as to stop the cigarette packet 400 (which may be other workpieces, and in the embodiment of the present application, the cigarette packet is taken as an example) moving to the bearing member. The mounting seat 110 may be shaped like a block or a plate, and is not limited in this embodiment. Alternatively, the mounting seat 110 is provided with a mounting hole 111, and the mounting seat can be mounted on the bearing component by a fastener 113 such as a bolt or a screw passing through the mounting hole 111.

The blowhead 120 has a flow channel s for flowing gas therethrough, and the first flow passage section 121 and the second flow passage section 122 are connected to each other and each define a part of the flow channel s. It is understood that the first flow-through section 121 is arranged in series with the second flow-through section 122 in the gas flow direction, and the first flow-through section 121 is not limited to being directly connected or indirectly connected with the second flow-through section 122. Indirect connection may be achieved via the third flow-through section.

The shapes of the first flow passage section 121 and the second flow passage section 122 are not particularly limited, and may be a circular pipe, a square pipe, or a special pipe, or may be a bent pipe or a straight pipe. In order to ensure the installation stability of blowhead 120, in one example, first flow-through section 121 and second flow-through section 122 are both made of hard material, such as hard plastic (e.g., phenolic plastic, polyurethane plastic, epoxy plastic, unsaturated polyester plastic), ceramic, metal, etc.

The extending direction of the second flow-through section 122 corresponds to the gas flow direction, and when the gas flows through the second flow-through section 122, the gas flows along the extending direction of the second flow-through section 122. Illustratively, the second flow-through section 122 is a straight tube, and then the extending direction thereof is the axial direction thereof. Further, for example, the second flow-through section 122 is an elbow, and the extending direction thereof is the central axis direction of the elbow.

Because the buffer portion 131 is protruded from the end of the second flow-through section 122 away from the first flow-through section 121, the buffer portion 131 is located at the downstream of the second flow-through section 122 in the gas flow direction, and the gas flow flows out through the second flow-through section 122, flows through the buffer portion 131, and is blown out toward the cigarette packet 400 moving toward the cigarette packet buffer structure 100. When cigarette packet 400400 moves toward cigarette packet buffer structure 100, it directly contacts buffer 131. The buffer portion 131 is a member capable of relaxing impact and energy consumption by elastic deformation, and may be a rubber buffer portion 131, a spring buffer portion 131, or the like, which is not limited in this embodiment.

The cigarette packet 400 is fed into the buffer device, and when the cigarette packet 400 moves towards the buffer device of the cigarette packet 400, the cigarette packet 400 is greatly decelerated under the action of the air flow blown by the air blowing head 120. When the cigarette packet 400 moves to the buffer device of the cigarette packet 400, the cigarette packet 400 impacts the buffer part 131, and the buffer part 131 absorbs and consumes the residual kinetic energy of the cigarette packet 400, so that the movement inertia of the cigarette in the cigarette packet 400 relative to the cigarette packet 400 is greatly reduced, and the quality problem that the cut tobacco is sunken towards the direction of the cigarette holder due to the movement inertia of the cigarette can be relieved and avoided. The buffer part 131 can also prevent the cigarette packet 400 from directly contacting the second circulation section 122 to generate surface scratches.

In some embodiments, referring to fig. 1 and fig. 2, the second flow-through section 122 has a position-limiting portion 122a disposed on the periphery thereof, the buffer 130 further has a sleeve portion 132 connected to the buffer portion 131, and the sleeve portion 132 is sleeved on the second flow-through section 122 and is limited between the first flow-through section 121 and the position-limiting portion 122 a.

The limiting portion 122a may be a limiting convex point or a limiting convex ring, and is not limited in particular. The socket 132 may be a socket or the like, and is not limited in particular.

At this time, the limiting portion 122a is provided to prevent the buffer 130 from separating from the blowhead 120, thereby ensuring the mounting reliability of the buffer 130.

In a further embodiment, the socket 132 is interferingly socket with the second flow-through section 122. Specifically, the inner diameter of the socket portion 132 is slightly smaller than the outer diameter of the second flow-through section 122, so that the socket portion 132 is tightly sleeved on the second flow-through section 122. For example, the inner diameter of the socket portion 132 is 7.5mm, and the outer diameter of the second flow-through section 122 can be 7.6 mm. The socket 132 may be made of soft rubber (e.g., nitrile rubber, butyl rubber).

Preferably, the socket portion 132 and the buffer portion 131 are integrally formed. Such as via injection molding of rubber (e.g., nitrile rubber, butyl rubber), is low cost and easy to manufacture.

In some embodiments, referring to fig. 1 and fig. 2, the limiting portion 122a is located at an end of the second flow-through section 122 away from the first flow-through section 121, the buffering portion 131 is disposed around the periphery of the limiting portion 122a, and in the extending direction of the second flow-through section 122, a portion of the buffering portion 131 extends beyond the range of the limiting portion 122 a.

The limiting portion 122a is disposed at one end of the second flow-through section 122, so that the length of the sleeving portion 132 can be increased as much as possible, and the installation of the buffer 130 is more reliable. When the cigarette packet 400 moves to the cigarette packet buffering structure 100, the buffer part 131 contacts with the part of the cigarette packet outside the range of the limiting part 122a, so that the buffer part 131 absorbs and consumes the kinetic energy of the buffer part, and the cigarette packet 400 is prevented from contacting with the limiting part 122 a.

Further, in the extending direction of the second flow-through section 122, the length of the portion of the buffer portion 131 that extends beyond the limit portion 122a is not less than 1.5 mm. Illustratively, the length of the portion of the buffer portion 131 extending beyond the stopper portion 122a is 2 mm. At this time, when the buffer portion 131 itself elastically deforms to absorb and consume the kinetic energy of the cigarette packet 400, it can be ensured that the cigarette packet 400 does not contact with the limiting portion 122a, and the limiting portion 122a is prevented from scratching the surface of the cigarette packet 400.

In some embodiments, referring to fig. 1 and fig. 2, the buffering portion 131 encloses to form a gas passage s, and the gas passage s is communicated with the second flow section 122. In the extending direction of the second flow passage section 122, the gas passage channel s is in a trumpet shape with the diameter gradually increasing towards the direction departing from the first flow passage section 121.

The gas flow is communicated with the second flow passage section 122, and the gas flows out of the second flow passage section 122, passes through the gas flow passage s and is blown to the cigarette packet 400. At this moment, the air passing flow channel s is in a horn shape with gradually increasing drift diameter, so that the larger contact area between the air passing flow channel s and the cigarette packet 400 can be ensured under the condition that the drift diameter of the second flowing section 122 is smaller to ensure the gas pressure, the absorption and the consumption of kinetic energy of the cigarette packet 400 can be accelerated, and the phenomenon that the surface of the cigarette packet 400 is scratched due to the contact with the second flowing section 122 is avoided.

Specifically, referring to fig. 2, the limiting portion 122a includes an annular protrusion surrounding the outer periphery of the second flow-through section 122, and the outer periphery of the annular protrusion is inclined relative to the outer periphery of the second flow-through section 122 to match the inner wall of the buffering portion 131.

When the buffer 130 is installed, the sleeve-joint portion 132 is sleeved on the second flow-through section 122, the flared airflow channel of the buffer portion 131 is abutted against and matched with the periphery of the annular protrusion, and the buffer portion 131 can be limited and positioned by the annular protrusion, which is beneficial to realizing the rapid installation of the buffer 130.

Optionally, the length of the socket 132 is equal to the length of the second flow-through section 122. Therefore, when the buffer piece 130 is installed at the bottom, the inclined periphery of the annular protrusion can be just clamped on the bell mouth of the buffer rubber pad, and the installation is convenient.

In a further embodiment, referring to fig. 2, an end of the annular protrusion in the extending direction of the second flow-through section 122 is configured to form a groove f, and the groove f is used for an external force to operate to mount the first flow-through section 121 on the mounting error.

Specifically, the recess f may be a straight groove, a cross groove, or the like, which facilitates an installer to rotate the first circulation section 121 and install it on the mounting seat 110 by using a screwdriver.

In some embodiments, the first flow-through section 121 has at least two fastening locations capable of being fixedly connected with the mounting base 110 in the extending direction thereof, and the first flow-through section 121 is operable to select one of the fastening locations to be fixedly connected with the mounting base 110 so as to adjust the spacing distance between the buffer 130 and the mounting base 110.

The first flow-through section 121 extends in a direction corresponding to the gas flow direction. When the gas flows through the first flow-through section 121, the gas flows in the extending direction of the first flow-through section 121. Illustratively, the first flow-through section 121 is a straight pipe, and then the extending direction thereof is the axial direction thereof. Further, for example, the first flow-through section 121 is a bent pipe, and then the extending direction thereof is the central axis direction of the bent pipe.

The buffer member 130 is mounted on the second flow-through section 122, and when the mounting seat 110 is fixedly connected to the fixed connection position closer to the second flow-through section 122, the buffer member 130 is closer to the mounting seat 110.

During actual operation, an installer can select one of the fixed connection positions to be fixedly connected with the mounting base 110 as required to adjust the distance between the buffer member 130 and the mounting base 110, so that the installer can conveniently adjust the position of the buffer member 130 according to conditions such as the actual size of the cigarette packet 400 and the like, and the buffering effect of the buffer member 130 is ensured.

Preferably, referring to fig. 1 and 2, the first flow-through section 121 is provided with an external thread portion 121a on the outer circumference, and the mounting seat 110 is provided with a threaded hole 112 matching with the external thread portion 121 a. At this time, the external thread portion 121a is configured to form a plurality of fixing positions of the second flow-through section 122 in the extending direction of the second flow-through section, and the fixing positions can be switched continuously. Further, a nut 140 is fitted over the external thread portion 121a for locking the first flow-through section 121 to the mounting seat 110. The nut 140 may be located on the same side of the mount 110 as the bumper 130, or may be located on a different side.

Of course, in other embodiments, the manner of realizing that the first circulation section 121 has at least two fixed fastening positions may also be: the first flow-through section 121 has a plurality of connection holes, each of which forms a fixing position, and the mounting base 110 has a connection member and a fitting hole, the connection member selectively connects the fitting hole and one of the connection holes to fixedly connect the mounting base 110 with the first flow-through section 121.

In some embodiments, the cigarette packet buffering structure 100 further comprises an air connector (not shown) for connecting an air source, and the air connector is mounted on the first circulation section 121 and is communicated with the first circulation section 121. The gas connector is specifically selected according to the type of gas source and is not limited herein.

Preferably, the air terminal and the bumper 130 are located on different sides of the mount 110. In this way, the first flow-through section 121 is partially located on one side of the mounting seat 110 and partially located on the other side of the mounting seat 110, and the first flow-through section 121 can be prevented from falling out of the mounting seat 110 by the air joint. Further, the first flow passage section 121 has an internal threaded portion 121b therein, and the air connector is threadedly coupled to the internal threaded portion 121b, so that the air connector is easily installed.

On the other hand, the embodiment of the present application further provides a tobacco bale conveying system, referring to fig. 5, the tobacco bale conveying system includes the first conveying passage 200, the second conveying passage 300, and the tobacco bale buffering structure 100 mentioned in any of the above embodiments. The outlet of the first conveying channel 200 intersects with the inlet of the second conveying channel 300, the cigarette packet buffering structure 100 is arranged at the inlet of the second conveying channel 300, and the buffering member 130 is arranged towards the first conveying channel 200. The cigarette packet buffer structure 100 is used for stopping the cigarette packets 400 conveyed through the first conveying channel 200, and the second conveying channel 300 is used for conveying the cigarette packets 400 stopped at the second conveying channel.

The first conveying path 200 and the second conveying path 300 may be based on conveying mechanisms such as a conveyor belt and a conveyor roller for transportation, and the specific form is not limited herein.

In actual operation, the cigarette packet 400 is conveyed from the first conveying channel 200 to the inlet of the second conveying channel 300, then the cigarette packet buffer structure 100 stops, and the second conveying channel 300 is started after the cigarette packet 400 stops and conveys the cigarette packet to a downstream station.

In the cigarette packet conveying system, when the cigarette packet 400 moves from the first conveying channel 200 to the cigarette packet 400 buffer device, the cigarette packet 400 is greatly decelerated under the action of the air flow blown by the air blowing head 120. When the cigarette packet 400 moves to the buffer device of the cigarette packet 400, the cigarette packet 400 impacts the buffer part 131, and the buffer part 131 absorbs and consumes the residual kinetic energy of the cigarette packet 400, so that the movement inertia of the cigarette in the cigarette packet 400 relative to the cigarette packet 400 is greatly reduced, and the quality problem that the cut tobacco is sunken towards the direction of the cigarette holder due to the movement inertia of the cigarette can be relieved and avoided. The buffer part 131 can also prevent the cigarette packet 400 from directly contacting the second circulation section 122 to generate surface scratches.

Understandably, the tobacco bale conveying system also comprises all the beneficial effects, which are not described in detail herein.

In some embodiments, the cigarette packet conveying system further comprises a sensor (not shown) disposed at the entrance of the second conveying passage 300 and used for detecting whether there is a stopped cigarette packet 400 on the second conveying passage 300. The second conveyor lane 300 is configured to act when the sensor detects a stopped cigarette packet 400.

The sensor can be a non-contact sensor such as a photoelectric sensor, an infrared sensor, a laser sensor and the like. Specifically, the sensor is arranged close to the cigarette packet buffering structure 100, and when the cigarette packet 400 is stopped after contacting the buffering part 131, the sensor can sense the stopped cigarette packet 400.

At this time, the second conveying channel 300 starts to operate after the sensor determines that the cigarette packet 400 is stopped on the second conveying channel, and the stopped cigarette packet 400 is conveyed to the next station, which is beneficial to ensuring that the conveyed cigarette packet 400 can be accurately conveyed to the next station without the problem that the cigarette packet 400 cannot smoothly enter the next station due to position deviation and the like.

According to the cigarette packet buffer structure 100 and the cigarette packet conveying system, when the cigarette packet 400 moves towards the cigarette packet 400 buffer device, the cigarette packet 400 is greatly decelerated under the action of the air flow blown out by the air blowing head 120. When the cigarette packet 400 moves to the buffer device of the cigarette packet 400, the cigarette packet 400 impacts the buffer part 131, and the buffer part 131 absorbs and consumes the residual kinetic energy of the cigarette packet 400, so that the movement inertia of the cigarette in the cigarette packet 400 relative to the cigarette packet 400 is greatly reduced, and the quality problem that the cut tobacco is sunken towards the direction of the cigarette holder due to the movement inertia of the cigarette can be relieved and avoided. The buffer part 131 can also prevent the cigarette packet 400 from directly contacting the second circulation section 122 to generate surface scratches.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
