[0001] The invention belongs to the technical field of cigarette production equipment, and in particular relates to a trademark paper valve body suction mechanism of a cigarette packaging machine. Background Art

[0002] The ZB45 cigarette packaging machine is the main model of our factory for producing hard box products. It integrates machinery, electricity and gas, and detects, monitors and processes the raw material feeding, product packaging quality, equipment operation status, etc. of the entire automated production process, and displays it on the OPC. Its production capacity can reach 8,000 cigarettes per minute (i.e. 400 packs / minute), which is a highly automated cigarette packaging production line. The unit has the characteristics of good packaging quality, high reliability, stable performance, easy operation and maintenance, and strong adaptability.

[0003] Among them, the trademark paper suction mechanism of the ZB45 cigarette packaging machine is used to suck the trademark papers in the paper warehouse one by one onto the box mold conveyor belt at the bottom, and then send them to the next process by the box mold conveyor belt.

[0004] However, in actual use, after the trademark paper is placed on the box mold conveyor belt, the suction cup needs to be separated from the trademark paper through the air release mechanism. During this process, the suction cup is connected to the outside world, and under the action of the suction pipe, a large amount of external gas passes through the suction cup, generating huge wind noise, which causes great harm to the physical and mental health of employees. Summary of the invention

[0005] The purpose of the present invention is to provide a trademark paper valve body suction mechanism for a cigarette packaging machine, so as to solve the problem of excessive noise caused by structural defects of the existing suction mechanism.

[0006] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows: A label paper valve body suction mechanism for a cigarette packaging machine, comprising: Rotate a rotating shaft mounted on the frame; A lifting rod is located below the paper storage and passes through the box mold conveyor belt, and the lifting rod is vertically slidably mounted on the frame; A first transmission mechanism, which is installed between the rotating shaft and the lifting rod and is used to drive the lifting rod to reciprocate up and down; A suction seat, the suction seat is fixedly mounted on the top of the lifting rod, a suction cup and a suction pipe are mounted on the suction seat, a connecting hole is opened on the suction seat, and the suction cup and the suction pipe are connected through the connecting hole; An air release mechanism, wherein the air release mechanism is installed on the suction seat; A valve, the valve being mounted on the air suction pipe, the valve comprising a valve stem; A second transmission mechanism, which is installed between the rotating shaft and the valve stem and is used to drive the valve stem to rotate back and forth to realize the opening and closing of the valve; When the valve is in an open state, the deflation mechanism is in a closed state; During the contact between the suction cup and the trademark paper in the paper bank, the valve is opened under the action of the second transmission mechanism to form adsorption of the trademark paper; When the suction cup drives the trademark paper to leave the paper bank and reach the box mold conveyor belt, the air release mechanism opens to connect the suction cup with the outside atmosphere; Before the deflation mechanism is opened, the valve is closed under the action of the second transmission mechanism.

[0007] It is further defined that the lifting rod is sleeved with a sliding sleeve, and the sliding sleeve is fixedly mounted on the frame; A cross bar is horizontally arranged on the lifting rod, and a sliding groove is vertically arranged on the frame.

[0008] Such a structural design completes the vertical sliding installation of the lifting rod and the frame through the mutual cooperation between the lifting rod and the sliding sleeve, the cross bar and the sliding groove. It has a simple structure, is easy to install, and is highly practical.

[0009] It is further defined that a bearing is installed on the crossbar, and the bearing is located in the slide groove.

[0010] This structural design uses bearings instead of cross bars to contact the slide slots, thereby converting the sliding friction between the cross bars and the slide slots into rolling friction between the bearings and the frame, reducing frictional resistance while extending service life, and is highly practical.

[0011] There are multiple lifting rods, and a first transmission mechanism is arranged between each lifting rod and the rotating shaft.

[0012] This structural design can absorb piles of trademark paper in multiple paper warehouses simultaneously through multiple lifting rods, thereby improving work efficiency and having strong practicality.

[0013] It is further defined that the first transmission mechanism includes a first cam plate, a first swing lever and a first connecting rod; The first cam plate is fixedly mounted on the rotating shaft, and a first cam ring groove is formed on the side wall of the first cam plate; The middle part of the first swing rod is rotatably mounted on the frame, and one end of the first swing rod is rotatably mounted with a first roller, and the first roller is located in the first cam ring groove; The first connecting rod is rotatably mounted on the free end of the first swing rod, and the free end of the first connecting rod is rotatably connected to the lifting rod.

[0014] Such a structural design forms a first transmission mechanism through the first cam plate, the first swing rod and the first connecting rod to realize the up and down reciprocating motion of the lifting rod, without occupying too much space under the lifting rod, which is convenient for the installation and maintenance of various components and has strong practicality.

[0015] It is further defined that the degassing mechanism comprises a reed fixedly mounted on the suction seat, a sealing plug is mounted on the reed, a degassing hole connected to the connecting hole is opened on the suction seat, and a free end of the degassing hole is connected to the outside; The free end of the reed is located outside the suction seat, and a stopper is installed on the frame, and the stopper is located on the movement path of the free end of the reed and below the free end of the reed; When the free end of the spring is not in contact with the stopper, the sealing plug is located in the vent hole to form a blockage for the vent hole; When the free end of the reed contacts the stopper, the sealing plug is separated from the air release hole, so that the suction cup is connected with the outside through the air release hole.

[0016] Such a structural design forms a deflation mechanism through the mutual cooperation of the reed, the sealing plug, the deflation hole and the block. The elastic force of the reed itself is used to drive the sealing plug to seal the deflation hole. The free end of the reed is then moved by the block to achieve the connection between the connecting hole and the outside atmosphere, thereby connecting the suction cup with the outside atmosphere to achieve automatic deflation. The structure is simple, and no additional control mechanism is required. It is very practical.

[0017] It is further defined that the second transmission mechanism includes a second cam plate, a second swing rod, a second connecting rod and a rocker; The second cam plate is fixedly mounted on the rotating shaft, and a second cam ring groove is formed on the side wall of the second cam plate; The middle part of the second swing rod is rotatably mounted on the frame, and one end of the second swing rod is rotatably mounted with a second roller, and the second roller is located in the second cam ring groove; The second connecting rod is rotatably mounted on the free end of the second swinging rod, the rocking arm is rotatably mounted on the free end of the second connecting rod, and the rocking arm is fixedly connected to the valve stem.

[0018] Such a structural design, through the second cam plate, the second swing rod, the second connecting rod and the rocker arm forming the second transmission mechanism, realizes the reciprocating rotation of the valve stem and then realizes the opening and closing of the valve. It has a simple structure, is easy to install and has strong practicality.

[0019] It is further defined that the valve is a ball valve.

[0020] With this structural design, a ball valve is selected as the valve, and the ball valve has the advantage of higher control accuracy.

[0021] It is further defined that a filter is installed on the suction pipe.

[0022] Such a structural design filters the external air sucked into the suction pipe through the suction cup through the filter, thereby preventing dust in the air from entering the suction mechanism through the suction pipe, and is highly practical.

[0023] The invention adopting the above technical solution has the following advantages: 1. Through the cooperation of the rotating shaft, the lifting rod, the first transmission mechanism, the suction seat, the suction cup, the air suction pipe, the air release mechanism, the valve and the second transmission mechanism, the valve is controlled to close when the suction cup is not in contact with the trademark paper by mechanical transmission, thereby avoiding wind noise during air suction and reducing the overall noise of the suction mechanism, so that the noise during trademark paper suction is reduced to less than 85 decibels; 2.

[0026] like Figure 1 to Figure 6 As shown, a label paper valve body suction mechanism of a cigarette packaging machine of the present invention comprises: Rotate a rotating shaft 1 mounted on the frame; A lifting rod 2 is located below the paper storage 7 and passes through the box mold conveyor belt 71, and the lifting rod 2 is vertically slidably mounted on the frame; A first transmission mechanism, which is installed between the rotating shaft 1 and the lifting rod 2, and is used to drive the lifting rod 2 to reciprocate up and down; The suction seat 4 is fixedly mounted on the top of the lifting rod 2. A suction cup 41 and a suction pipe 42 are mounted on the suction seat 4. A connecting hole 43 is opened on the suction seat 4. The suction cup 41 and the suction pipe 42 are connected through the connecting hole 43. The deflation mechanism is installed on the suction seat 4; Valve 5, valve 5 is installed on the air suction pipe 42, valve 5 comprises a valve stem 50; The second transmission mechanism is installed between the rotating shaft 1 and the valve stem 50, and is used to drive the valve stem 50 to rotate back and forth to realize the opening and closing of the valve 5; When valve 5 is in the open state, the deflation mechanism is in the closed state; During the contact between the suction cup 41 and the trademark paper 70 in the paper bank 7, the valve 5 is opened under the action of the second transmission mechanism to form the suction of the trademark paper 70; When the suction cup 41 drives the trademark paper 70 to leave the paper bank 7 and reach the box mold conveyor belt 71, the deflation mechanism opens to connect the suction cup 41 to the outside atmosphere; Before the deflation mechanism opens, the valve 5 is closed under the action of the second transmission mechanism.

[0027] like Figure 1 As shown, the lifting rod 2 is sleeved with a sliding sleeve 21, and the sliding sleeve 21 is fixedly mounted on the frame; A cross bar 22 is horizontally arranged on the lifting rod 2, and a slide groove 23 is vertically arranged on the frame.

[0028] In fact, according to actual conditions, a lifting rod 2 with a rectangular cross-section can be used to cooperate with the rectangular through hole opened on the frame to realize the vertical sliding installation of the lifting rod 2. In this embodiment, the lifting rod 2 and the frame are vertically slidably installed through the cooperation between the lifting rod 2 and the sliding sleeve 21, the cross bar 22 and the sliding groove 23. The structure is simple, the installation is convenient, and the practicability is strong.

[0029] like Figure 1 As shown, a bearing 220 is installed on the cross bar 22 , and the bearing 220 is located in the slide groove 23 .

[0030] The bearing 220 replaces the cross bar 22 in contact with the slide groove 23, thereby converting the sliding friction between the cross bar 22 and the slide groove 23 into rolling friction between the bearing 220 and the frame, thereby reducing friction resistance and extending service life, and having strong practicality.

[0031] There are multiple lifting rods 2, and a first transmission mechanism is provided between each lifting rod 2 and the rotating shaft 1.

[0032] In fact, only one lifting rod 2 may be provided according to actual conditions. In this embodiment, multiple lifting rods 2 are used to simultaneously absorb the piles of trademark papers 70 in multiple paper storage bins 7, thereby improving work efficiency and having strong practicality.

[0033] like Figure 1 and Figure 2 As shown, the first transmission mechanism includes a first cam plate 3, a first swing rod 31 and a first connecting rod 32; The first cam plate 3 is fixedly mounted on the rotating shaft 1, and a first cam ring groove 30 is formed on the side wall of the first cam plate 3; The middle part of the first swinging rod 31 is rotatably mounted on the frame, and one end of the first swinging rod 31 is rotatably mounted with a first roller 310, which is located in the first cam ring groove 30; The first connecting rod 32 is rotatably mounted on the free end of the first swing rod 31 , and the free end of the first connecting rod 32 is rotatably connected to the lifting rod 2 .

[0034] In fact, according to actual conditions, a rolling wheel can be set at the lower end of the lifting rod 2, and a cam can be installed on the rotating shaft 1 so that the rolling wheel rests on the cam. A compression spring can be set between the lifting rod 2 and the frame to compress the lifting rod 2 downward to achieve the up and down reciprocating motion of the lifting rod 2. In this embodiment, the first transmission mechanism is formed by the first cam plate 3, the first swing rod 31 and the first connecting rod 32 to achieve the up and down reciprocating motion of the lifting rod 2. There is no need to occupy too much space under the lifting rod 2, which is convenient for the installation and maintenance of various components and has strong practicality.

[0035] like Figure 5 and Figure 6 As shown, the deflation mechanism includes a reed 44 fixedly mounted on the suction seat 4, a sealing plug 440 is mounted on the reed 44, a deflation hole connected to the connecting hole 43 is opened on the suction seat 4, and the free end of the deflation hole is connected to the outside; The free end of the reed 44 is located outside the suction seat 4, and a stopper 441 is installed on the frame. The stopper 441 is located on the movement path of the free end of the reed 44 and below the free end of the reed 44; When the free end of the spring 44 is not in contact with the stopper 441, the sealing plug 440 is located in the vent hole to block the vent hole; When the free end of the spring 44 contacts the stopper 441 , the sealing plug 440 is separated from the vent hole, so that the suction cup 41 is connected to the outside through the vent hole.

[0036] In fact, according to the actual situation, it is also possible to choose to install a travel switch and a piston rod on the suction seat 4, monitor the movement position of the suction seat 4 with the travel switch, and then control the piston rod to complete the sealing and releasing of the venting hole according to the monitoring data. In this embodiment, the spring 44, the sealing plug 440, the venting hole and the block 441 cooperate with each other to form a venting mechanism, and the elastic force of the spring 44 itself is used to drive the sealing plug 440 to seal the venting hole, and then the block 441 is used to move the free end of the spring 44 to achieve the connection between the connecting hole 43 and the outside atmosphere, and then the suction cup 41 is connected with the outside atmosphere to achieve automatic deflation. The structure is simple and no additional control mechanism is required, so it is very practical.

[0037] like Figure 2-Figure 4 As shown, the second transmission mechanism includes a second cam plate 6, a second swing rod 61, a second connecting rod 62 and a rocker 63; The second cam plate 6 is fixedly mounted on the rotating shaft 1, and a second cam ring groove 60 is formed on the side wall of the second cam plate 6; The middle part of the second swinging rod 61 is rotatably mounted on the frame, and a second roller 610 is rotatably mounted on one end of the second swinging rod 61 , and the second roller 610 is located in the second cam ring groove 60 ; The second connecting rod 62 is rotatably mounted on the free end of the second swing rod 61 , and the rocking arm 63 is rotatably mounted on the free end of the second connecting rod 62 . The rocking arm 63 is fixedly connected to the valve stem 50 .

[0038] The second transmission mechanism is formed by the second cam plate 6, the second swing rod 61, the second connecting rod 62 and the rocker 63 to realize the reciprocating rotation of the valve stem 50, and then realize the opening and closing of the valve 5. The structure is simple, the installation is convenient, and the practicability is strong.

[0039] The second transmission mechanism includes a first gear, a door frame, a first rack, a second rack and a second gear; The first gear is mounted on the rotating shaft 1; The door frame is installed on the frame in a vertical sliding manner; There are two first racks, which are respectively located on both sides of the inner wall of the door frame, and the two first racks are located at different heights on the inner wall of the door frame; The second rack is fixedly arranged on the top of the gate frame, and the second gear is fixedly installed on the valve stem 50 and meshed with the second rack.

[0040] By locating the two first racks at different heights on the inner wall of the gate frame, the two first racks can mesh with the first gear at different times, thereby driving the gate frame to reciprocate. Then, the second rack arranged at the upper end of the gate frame cooperates with the second gear mounted on the valve stem 50 and meshing with the second rack. The gate frame drives the second rack to reciprocate, thereby driving the valve stem 50 to reciprocate, thereby realizing the opening and closing of the valve 5.

[0041] Valve 5 is a ball valve.

[0042] In fact, a butterfly valve may be selected as the valve 5 according to actual conditions. In this embodiment, a ball valve is selected as the valve 5, and the ball valve has the advantage of higher control accuracy.

[0043] A filter 45 is mounted on the air suction pipe 42 .

[0044] The external air sucked into the suction pipe 42 through the suction cup 41 is filtered by the filter 45 to prevent dust in the air from entering the suction mechanism through the suction pipe 42, which is highly practical.

[0045] In this embodiment, when in use, the external mechanism drives the rotating shaft 1 to rotate, thereby driving the first cam plate 3 and the second cam plate 6 to rotate; During the rotation of the first cam plate 3, the lifting rod 2 is driven to move up and down through the first transmission mechanism; During the rotation of the second cam plate 6, the valve stem 50 is driven to reciprocate through the second transmission mechanism; When the lifting rod 2 rises to the point where the suction cup 41 contacts the trademark paper 70 in the paper bank 7, the valve 5 is opened under the action of the second transmission mechanism, the free end of the reed 44 does not contact the stopper 441, the sealing plug 440 is located in the air release hole, and the air release mechanism is in a closed state. At this time, the suction cup 41 is in a negative pressure state under the action of the air suction pipe 42, and the trademark paper 70 in the paper bank 7 is adsorbed; After the adsorption is completed, the lifting rod 2 moves downward, and the adsorbed trademark paper 70 is driven downward by the suction cup 41, so that the trademark paper 70 is separated from the paper bank 7, until the trademark paper 70 reaches the box mold conveyor belt 71. At this time, the free end of the reed 44 contacts the stopper 441, so that the sealing plug 440 is separated from the vent hole, and the negative pressure state in the suction cup 41 is destroyed, and the suction cup 41 no longer adsorbs the trademark paper 70; At the same time, after the adsorption is completed and before the degassing mechanism is opened, the valve 5 is closed under the action of the second transmission mechanism; When the suction cup 41 no longer forms suction on the trademark paper 70, the suction cup 41 is driven by the lifting rod 2 to fall below the box mold conveyor belt 71, and the trademark paper 70 is located on the box mold conveyor belt 71, and the box mold conveyor belt 71 drives the trademark paper 70 to move to the next station; When the box mold conveyor belt 71 drives the trademark paper 70 to leave from directly above the suction cup 41, the lifting rod 2 moves upward again under the action of the first cam plate 3 and the first transmission mechanism, and the deflation mechanism is closed again before the valve 5 is reopened. Until the lifting rod 2 rises to the point where the suction cup 41 contacts the trademark paper 70 in the paper bank 7, the valve 5 is reopened to adsorb the trademark paper 70 in the paper bank 7 for the second time.

[0046] The above is a detailed introduction to the trademark paper valve body suction mechanism of a cigarette packaging machine provided by the present invention. The description of the specific embodiment is only used to help understand the method and core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
