Description

Technical Field

[0001] This application relates to the field of cigarette production technology, and in particular to a cigarette packaging expansion device. Background Technology

[0002] During the cigarette manufacturing process, after the cigarettes are prepared, they need to be packaged into small boxes. Currently, the factory has a type of cigarette with single-layer cardboard packaging. After the cardboard packaging box is folded and glued into shape, the empty cardboard packaging box is transported to a designated position by a conveyor belt or other conveyor tools. Then, a special cigarette pushing tool pushes the entire cigarette pack into the flat packaging box. In actual operation, it has been found that because the entrance of the packaging box has a folded edge for later sealing, during the transportation process, the folded edge will droop downward under the influence of gravity. Therefore, when pushing the cigarette pack into the packaging box, the folded edge on the top side of the packaging box can easily obstruct and interfere with the cigarettes, which can easily cause damage to the cigarettes and affect product quality. Utility Model Content

[0003] The purpose of this application is to provide a cigarette packaging expansion device that can lift the top of the packaging box, causing the top of the packaging box to arch upwards, thereby effectively solving the shortcomings of the prior art.

[0004] Therefore, this application provides a cigarette packaging expansion device, comprising:

[0005] A limiting component is used to position and restrict the movement of the small packaging box along a first direction;

[0006] The nozzle can reciprocate along a first direction, and the nozzle is used to lift the top center of the packaging box;

[0007] A negative pressure pipe is connected to the suction nozzle to generate negative pressure at the suction nozzle and suck up the top of the packaging box or to release the packaging box when the negative pressure is lost.

[0008] A drive device is connected to the suction nozzle to drive the suction nozzle to reciprocate along a first direction;

[0009] The limiting member acts on both sides of the packaging box in a second direction. The first direction is vertical, and the second direction is horizontal and perpendicular to the opening direction of the packaging box.

[0010] In some possible implementations, a conveyor belt and a support frame are also included, with the support frame located above the conveyor belt. A gap space is formed between the conveyor belt and the support frame for conveying small packaging boxes. The conveyor belt is provided with raised ribs, and the support frame is provided with blocking elements. The blocking elements and the raised ribs cooperate to form a limiting element.

[0011] In some possible implementations, the blocking element and the rib act on the two side edges of the packaging box in a second direction, respectively.

[0012] In some possible implementations, the number of the blocking elements is two, and the two blocking elements are arranged on the support frame along the opening direction of the packaging box.

[0013] In some possible implementations, the driving device is a cylinder, which is mounted on a support frame and located between two blocking members, and the suction nozzle is connected to the output end of the cylinder.

[0014] In some possible implementations, the blocking member is an elastic member that can elastically abut against the side of the packaging box in a second direction.

[0015] In some possible implementations, the blocking element is a long, thin sheet, with one end connected to the support frame and the other end extending obliquely toward the conveyor belt.

[0016] In some possible implementations, the end of the blocking member extending toward the conveyor belt is provided with an arched portion, which is arranged in an arc shape toward the conveyor belt.

[0017] In some possible implementations, one end of the blocking member is connected to the support frame, and the other end of the blocking member is inclined toward the conveying direction of the conveyor belt.

[0018] In some possible implementations, the support frame is movably configured relative to the conveyor belt.

[0019] According to the embodiments of this application, the cigarette packaging expansion device includes a limiting member, a mouthpiece, a negative pressure pipe, and a driving device. The limiting member can restrict the movement of the small box in the vertical direction. The negative pressure pipe can generate negative pressure in the mouthpiece, thereby adsorbing the top of the small box. Under the drive of the driving device, the mouthpiece can move in the vertical direction, thereby pulling the top of the small box upward to a certain extent, causing the top of the small box to arch upward, thereby effectively preventing the folded edge of the top of the small box from interfering with the cigarette and avoiding damage to the cigarette.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] like Figures 1-7 As shown, this application provides a cigarette packaging expansion device applied in the cigarette packaging process of a cigarette factory. After the cigarettes are manufactured, they need to be pushed into a small packaging box in groups. For single-layer cardboard packaging, after the cardboard box is folded and glued, the empty cardboard box is transported to a designated location by a conveyor belt or other tools. Then, a special cigarette pushing tool pushes the group of cigarettes into the flat packaging box. In actual operation, it has been found that because the entrance of the packaging box is equipped with a foldable folded edge for easy sealing later, during the transportation of the packaging box, the folded edge on the top of the packaging box will droop slightly due to gravity. When the group of cigarettes is pushed into the packaging box, the drooping folded edge can easily interfere with the cigarettes, which can damage the cigarettes and affect product quality. The cigarette packaging expansion device provided in this application aims to eliminate the interference of the folded edge on the top of the packaging box with the cigarettes.

[0029] The cigarette packaging expansion device includes a limiting member, a mouthpiece 100, a negative pressure pipe 101, and a driving device 200. It operates along a first direction and a second direction, the first direction being vertical and the second direction being horizontal, perpendicular to the opening direction of the small packaging box. The small packaging box is flat and lies horizontally. The limiting member restricts the movement of the small packaging box along the first direction. The mouthpiece 100 can reciprocate along the first direction. The mouthpiece 100 is used to grasp the upper center of the small packaging box and pull it upwards. The top center of the small box refers to the middle part of the top of the small box along the second direction. Pulling the top center upward to a certain extent causes the top center of the small box to bulge upward, thereby widening the opening of the small box. Due to the rigidity of the cardboard, the top of the opening of the small box also arches upward, preventing the top edge from drooping downward. This makes the opening of the small box relatively larger, facilitating the pushing of the cigarette pack into the box. The cigarette pack is pushed in more smoothly, preventing interference with the cigarettes, avoiding damage to the cigarettes, and preventing product quality problems.

[0030] The negative pressure pipe 101 connects to the mouthpiece 100, enabling the mouthpiece 100 to generate negative pressure and adhere to the top of the packaging box, or to release the negative pressure and release the packaging box. When the packaging box moves, a limiting component acts on it to restrict its vertical movement. Then, the drive device 200 drives the mouthpiece 100 downwards to contact the top of the packaging box, generating negative pressure to adhere to the top of the packaging box. The drive device 200 then drives the mouthpiece 100 upwards, pulling up the top of the packaging box and pushing the cigarette into it. When the negative pressure at the suction nozzle 100 disappears, the top of the packaging box is released, and the packaging box is conveyed to the next process. Then, a new packaging box is conveyed to repeat the above steps. The degree to which the suction nozzle 100 pulls the packaging box to the top can be set according to the actual situation. Preferably, after the suction nozzle 100 sucks the packaging box to the top, it moves up 2-5 mm. Preferably, the negative pressure pipe 101 includes a flexible pipe. One end of the flexible pipe is connected to the suction nozzle 100, and the other end of the flexible pipe is connected to the negative pressure fan. The generation and disappearance of negative pressure at the suction nozzle 100 are achieved by controlling the negative pressure fan.

[0031] In one embodiment, the system further includes a conveyor belt 300 and a support frame 400. The support frame 400 is located above the conveyor belt 300, and a gap space for conveying small packaging boxes is formed between the conveyor belt 300 and the support frame 400. The conveyor belt 300 is provided with protruding ribs 502, and the support frame 400 is provided with blocking members 501. The blocking members 501 and the protruding ribs 502 cooperate to form a limiting member. The top of the conveyor belt 300 is used to convey small packaging boxes. The conveying direction of the conveyor belt 300 is horizontal and parallel to a second direction. Multiple protruding ribs 502 are arranged at intervals on the conveyor belt 300, and a gap space for accommodating small packaging boxes is formed between two adjacent protruding ribs 502. The protruding ribs 502 can... The packaging box is restricted in the horizontal direction. One packaging box is accommodated between every two adjacent protruding ribs 502. Two adjacent protruding ribs 502 are selected, and there is a packaging box between the two protruding ribs 502. Along the conveying direction of the conveyor belt 300, the two protruding ribs 502 are the upstream protruding ribs 502 and the downstream protruding ribs 502, respectively. When the conveyor belt 300 moves the packaging box to the blocking member 501, the blocking member 501 and the upstream protruding ribs 502 cooperate to clamp the packaging box to a certain extent to restrict the movement of the packaging box in the vertical direction. At this time, the conveyor belt 300 stops running. After the cigarette pushing tool pushes the cigarette into the packaging box, the conveyor belt 300 resumes running.

[0032] Preferably, the blocking member 501 and the rib 502 act on the two sides of the packaging box in the second direction. In one example, there are two blocking members 501. The two blocking members 501 are arranged on the support frame 400 along the opening direction of the packaging box. The two blocking members 501 act on the downstream side of the packaging box in the second direction. The two blocking members 501 and the rib 502 work together to make the packaging box more stable.

[0033] In some embodiments, the driving device 200 is a cylinder, which is mounted on the support frame 400 and located between two blocking members 501. The suction nozzle 100 is connected to the output end of the cylinder. The support frame 400 is generally plate-shaped. The space formed between the support frame 400 and the conveyor belt 300 allows the packaging box to move. When the support frame 400 is horizontally placed above the conveyor belt 300, the gap between the bottom of the support frame 400 and the conveyor belt 300 is greater than the thickness of the packaging box to ensure that the top of the packaging box can bulge upward. A mounting frame 402 can be provided on the top of the support frame 400. The cylinder body is mounted on the mounting frame 402. The output end of the cylinder extends vertically downward. The suction nozzle 100 is located at the output end of the cylinder. Under the driving action of the cylinder, the suction nozzle 100 can move in the vertical direction. A through window is provided on the support frame 400 for the suction nozzle 100 to move so that the suction nozzle 100 can adsorb the packaging box.

[0034] More preferably, the blocking member 501 is an elastic member, which can elastically abut against the side of the packaging box in the second direction. More preferably, the blocking member 501 is a long thin sheet, with one end connected to the support frame 400 and the other end extending inclinedly toward the conveyor belt 300. That is, one end of the blocking member 501 is connected to the support frame 400, and the other end extends inclinedly toward the conveying direction of the conveyor belt 300. The minimum distance between the blocking member 501 and the conveyor belt 300 is... The distance is slightly less than the thickness of the packaging box. Thus, when the packaging box moves to the blocking member 501, the blocking member 501 and the rib 502 cooperate to act on the two sides of the packaging box in the second direction, thereby limiting the packaging box. After the cigarette is pushed, under the conveying of the conveyor belt 300 and the limiting action of the rib 502, the packaging box applies a force to the blocking member 501. Under the elastic action of the blocking member 501, the blocking member 501 is lifted up, thereby conveying the packaging box that has been pushed away. In this way, the packaging box can be limited so that it can be pulled up and pushed, without affecting the normal operation and conveying of the packaging box.

[0035] More preferably, the end of the blocking member 501 extending toward the conveyor belt 300 is provided with an arched portion 5011. The arched portion 5011 is arc-shaped in the direction toward the conveyor belt 300. The arched portion 5011 is used to contact the top edge of the downstream side of the packaging box in the second direction. The blocking member 501 is long and thin. One end of the blocking member 501 is connected to the support frame 400, and the other end of the blocking member 501 is arc-shaped downward and downstream. Near the end of this other end, an arc-shaped arch with a smaller arc angle is formed, arching toward the conveyor belt 300 to form the arched portion 5011. Thus, in the direction of the conveyor belt 300, the arched portion 5011 is formed. Under the conveying action of 00, when the small packaging box moves to the cigarette pushing station, the arched part 5011 just abuts against the top of the upstream edge of the small packaging box. Only the arched part 5011 contacts the small packaging box, making the subsequent forward conveying of the small packaging box smoother. Moreover, when limiting the small packaging box, the contact area between the blocking part 501 and the small packaging box is smaller, avoiding interference with the upper arch. In this embodiment, the material of the blocking part 501 is an elastic material, and the plane where the bending direction of the blocking part 501 is located is perpendicular to the plane where the flat surface of the blocking part 501 is located, making the elastic deformation of the blocking part 501 smoother. After the cigarette pushing is completed, the small packaging box is prevented from getting stuck during conveying.

[0036] More preferably, a through groove 401 is provided on the support frame 400. The through groove 401 has a certain length and extends through the support frame 400 along the thickness direction. One end of the blocking member 501 is connected to the top of the support frame 400. The width of the blocking member 501 is smaller than the width of the through groove 401. The other end of the blocking member 501 extends downward from the through groove 401 to touch the packaging box. In this way, the blocking member 501 avoids occupying the space between the support frame 400 and the conveyor belt 300, and prevents the packaging box from getting stuck. The length direction of the through groove 401 is parallel to the second direction, and the extension direction of the blocking member 501 is parallel to the second direction. After the cigarette pushing action is completed, the packaging box can more easily overcome the elasticity of the blocking member 501 to complete the conveying. The two blocking members 501 are arranged along the opening direction of the packaging box. In the opening direction of the packaging box, the mouthpiece 100 is located between the two blocking members 501, which makes it more stable when pulling the packaging box upward.

[0037] The support frame 400 is movable relative to the conveyor belt 300. Preferably, the support frame 400 can be hinged to the conveyor belt 300 to facilitate the opening of the support frame 400 for inspection of parts, packaging boxes, etc.
