Description

Technical Field

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

[0002] The label paper suction mechanism of the ZB45 cigarette packaging machine is used to suck the stacked label papers 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.

[0003] The noise generated when the trademark paper is sucked is as high as over 95 decibels, which is the biggest noise source of ZB45. The noise is mainly the wind noise generated when the trademark paper is sucked away from the suction cup.

[0004] In order to reduce noise and protect the health of employees, the ZB45 trademark paper suction mechanism was modified to control the on and off of the suction air. Suction air was supplied when sucking the trademark paper, and the suction air was turned off after the suction of the trademark paper was completed, thereby avoiding the wind noise generated during empty suction and reducing the noise during trademark paper suction to less than 85 decibels. Summary of the invention

[0005] The purpose of the present invention is to provide a trademark paper air valve type 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:

[0007] A trademark paper air valve type suction mechanism for a cigarette packaging machine, comprising:

[0008] Rotate a rotating shaft mounted on the frame;

[0009] 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;

[0010] A 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;

[0011] A suction seat, the suction seat is fixedly mounted on the top of the lifting rod, a suction cup and a connecting pipe are mounted on the suction seat, a connecting hole is opened on the suction seat, and the suction cup and the connecting pipe are connected through the connecting hole;

[0012] An on-off mechanism, the on-off mechanism comprising a support and a valve plate;

[0013] The support is fixedly mounted on the frame, the support is a hollow structure, and two mounting holes are provided on the support, one of the mounting holes is connected to the connecting pipe, and the other mounting hole is connected to the suction pipe;

[0014] The valve plate is located in the support and fixedly mounted on the rotating shaft, and a slot is provided on the valve plate;

[0015] An air release mechanism connected to the connecting pipe;

[0016] When the air release mechanism is in an open state, the connecting pipe is connected to the outside atmosphere;

[0017] When the slotted hole moves to be connected with two mounting holes at the same time, the on-off mechanism is in a connected state;

[0018] When the on-off mechanism is in a connected state, the deflation mechanism is in a closed state;

[0019] During the contact between the suction cup 41 and the trademark paper 60 in the paper bank 6, the on-off mechanism is in a connected state, forming an adsorption of the trademark paper 60;

[0020] When the suction cup 41 drives the trademark paper 60 to leave the paper bank 6 and reach the box mold conveyor belt 61, the degassing mechanism is opened to connect the suction cup 41 with the outside atmosphere;

[0021] Before the deflation mechanism is opened, the on-off mechanism is in a closed state.

[0022] It is further defined that the deflation mechanism includes a secondary hole formed on the support, and the secondary hole is located on the movement trajectory of the slot hole;

[0023] When the slot hole moves to be connected with the mounting holes corresponding to the auxiliary hole and the connecting pipe, and is not connected with the mounting hole corresponding to the air suction pipe, the deflation mechanism is in an open state, and the on-off mechanism is in a connected state.

[0024] This structural design uses the auxiliary hole as the deflation mechanism and cooperates with the slot hole on the valve plate to connect the suction pipe, the connecting pipe and the auxiliary hole respectively at different rotation angles, thereby satisfying the deflation function of the suction cup while meeting the adsorption requirements of the suction cup. It has a simple structure, is easy to use and has strong practicality.

[0025] It is further defined that the two mounting holes are respectively mounted on two sides of the support, and the central axes of the two mounting holes coincide with each other;

[0026] A secondary groove is formed on one side of the valve plate close to the connecting pipe, the depth of the secondary groove is smaller than the thickness of the valve plate, and the secondary groove is connected to the slot hole;

[0027] When the slot hole moves to communicate with the auxiliary hole, the valve plate blocks the air suction pipe.

[0028] Such a structural design, through the setting of the auxiliary groove, after the slot hole rotates over the mounting hole to form a blockage for the mounting hole, utilizes the connection between the auxiliary groove and the slot hole to complete the connection between the connecting pipe and the auxiliary hole, thereby realizing the function of the deflation mechanism being in the open state and the on-off mechanism being in the connected state. The structure is simple and practical.

[0029] It is further defined that the mounting hole corresponding to the connecting pipe is located between the mounting hole corresponding to the air suction pipe and the auxiliary hole;

[0030] When the slot hole moves to communicate with the auxiliary hole, the valve plate blocks the air suction pipe.

[0031] Such a structural design limits the position of the secondary hole. When the slot hole passes the mounting hole position corresponding to the suction pipe, the mounting hole corresponding to the suction pipe is blocked, thereby completing the connection between the connecting pipe and the secondary hole, thereby realizing the functions of the air release mechanism being in an open state and the on-off mechanism being in a connected state. The structure is simple and practical.

[0032] It is further defined that a secondary tube is installed in the secondary hole, and a filter membrane is installed on the secondary tube.

[0033] With this structural design, the filter membrane is installed through the auxiliary pipe, which can filter the gas entering the on-off mechanism through the auxiliary hole, thereby preventing dust in the gas from entering the on-off mechanism through the suction pipe, and is highly practical.

[0034] 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;

[0035] 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;

[0036] 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;

[0037] When the free end of the spring sheet contacts the stopper, the sealing plug is separated from the vent hole, so that the suction cup is connected to the outside through the vent hole.

[0038] 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.

[0039] It is further defined that the lifting rod is sleeved with a sliding sleeve, and the sliding sleeve is fixedly mounted on the frame;

[0040] A cross bar is horizontally arranged on the lifting rod, and a sliding groove is vertically arranged on the frame.

[0041] 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.

[0042] It is further defined that the transmission mechanism includes a cam plate, a swing rod and a connecting rod;

[0043] The cam plate is fixedly mounted on the rotating shaft, and a cam ring groove is formed on the side wall of the cam plate;

[0044] The middle part of the swing rod is rotatably mounted on the frame, and one end of the swing rod is rotatably mounted with a roller, which is located in the cam ring groove;

[0045] The connecting rod is rotatably mounted on the free end of the swing rod, and the free end of the connecting rod is rotatably connected to the lifting rod.

[0046] This structural design, through the cam plate, swing rod and connecting rod to form a transmission mechanism, realizes the up and down reciprocating motion of the lifting rod, does not need to occupy too much space under the lifting rod, is convenient for the installation and maintenance of various components, and is highly practical.

[0047] It is further defined that a filter is installed on the connecting pipe.

[0048] Such a structural design filters the external air sucked into the connecting pipe through the suction cup through the filter, thereby preventing dust in the air from entering the suction mechanism through the connecting pipe, and is highly practical.

[0049] The invention adopting the above technical solution has the following advantages:

[0050] 1. Through the cooperation of the rotating shaft, lifting rod, transmission mechanism, suction seat, suction cup, air suction pipe, connecting pipe, on-off mechanism, air release mechanism and valve plate with slots, the on-off mechanism is controlled to be closed when the suction cup is not in contact with the trademark paper by mechanical transmission, so as to avoid wind noise during air suction, thereby reducing the overall noise of the suction mechanism and reducing the noise during trademark paper suction to less than 85 decibels;

[0051] 2. The auxiliary hole is used as the deflation mechanism, and the slot hole on the valve plate is matched. At different rotation angles, the suction pipe, the connecting pipe and the auxiliary hole are connected respectively, so that the deflation function of the suction cup is satisfied on the basis of meeting the adsorption demand of the suction cup. The structure is simple, easy to use and practical.

[0052] 3. Through the setting of the auxiliary groove, after the slot hole passes the position of the mounting hole and the mounting hole is blocked, the connection between the auxiliary groove and the slot hole is used to complete the connection between the connecting pipe and the auxiliary hole, thereby realizing the function of the deflation mechanism being in the open state and the on-off mechanism being in the connected state, the structure is simple and the practicability is strong;

[0053] 4. By limiting the position of the auxiliary hole, when the slot hole passes the installation hole position corresponding to the air suction pipe, the installation hole corresponding to the air suction pipe is blocked, and the connection between the connecting pipe and the auxiliary hole is completed, thereby realizing the function that the deflation mechanism is in the open state and the on-off mechanism is in the connected state, the structure is simple and the practicality is strong;

[0054] 5. The deflation mechanism is formed by the 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 moved by the block to realize the connection between the connecting hole and the outside atmosphere, thereby connecting the suction cup with the outside atmosphere to realize automatic deflation. The structure is simple, and no additional control mechanism is required, so it is very practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions of the specification, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.

[0080] Embodiment 1:

[0081] like Figure 1 to Figure 7 As shown, a trademark paper air valve type suction mechanism of a cigarette packaging machine of the present invention comprises:

[0082] Rotate a rotating shaft 1 mounted on the frame;

[0083] A lifting rod 2 is located below the paper bank 6 and is inserted into the box mold conveyor belt 61. The lifting rod 2 is vertically slidably mounted on the frame;

[0084] The transmission mechanism 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;

[0085] The suction seat 4 is fixedly mounted on the top of the lifting rod 2. A suction cup 41 and a connecting pipe 420 are mounted on the suction seat 4. A connecting hole 43 is opened on the suction seat 4. The suction cup 41 and the connecting pipe 420 are connected through the connecting hole 43.

[0086] The on-off mechanism includes a support 51 and a valve plate 52;

[0087] The support 51 is fixedly mounted on the frame. The support 51 is a hollow structure. Two mounting holes are provided on the support 51. One mounting hole is connected to the connecting pipe 420, and the other mounting hole is connected to the suction pipe 42.

[0088] The valve plate 52 is located in the support 51 and is fixedly mounted on the rotating shaft 1. A slot 520 is formed on the valve plate 52.

[0089] An air release mechanism connected to the connecting pipe 420;

[0090] When the deflation mechanism is in the open state, the connecting pipe 420 is connected to the outside atmosphere;

[0091] When the slot hole 520 moves to be connected with the two mounting holes at the same time, the on-off mechanism is in a connected state;

[0092] When the on-off mechanism is in the connected state, the deflation mechanism is in the closed state;

[0093] During the contact between the suction cup 41 and the trademark paper 60 in the paper bank 6, the on-off mechanism is in a connected state, forming an adsorption of the trademark paper 60;

[0094] When the suction cup 41 drives the trademark paper 60 to leave the paper bank 6 and reach the box mold conveyor belt 61, the deflation mechanism opens to connect the suction cup 41 to the outside atmosphere;

[0095] Before the deflation mechanism is opened, the on-off mechanism is in the closed state.

[0096] The deflation mechanism includes a secondary hole formed on the support 51, and the secondary hole is located on the movement track of the slot 520;

[0097] When the slot hole 520 moves to communicate with the mounting holes corresponding to the auxiliary hole and the connecting pipe 420 and is not connected with the mounting hole corresponding to the air suction pipe 42, the deflation mechanism is in an open state and the on-off mechanism is in a connected state.

[0098] By using the auxiliary hole as a deflation mechanism in conjunction with the slot hole 520 on the valve plate 52, the suction pipe 42, the connecting pipe 420 and the auxiliary hole are connected respectively at different rotation angles, thereby satisfying the deflation function of the suction cup 41 while satisfying the adsorption demand of the suction cup 41. The structure is simple, the use is convenient, and the practicability is strong.

[0099] The two mounting holes are respectively installed on both sides of the support 51, and the central axes of the two mounting holes coincide with each other;

[0100] A secondary groove 521 is formed on one side of the valve plate 52 close to the connecting pipe 420. The depth of the secondary groove 521 is smaller than the thickness of the valve plate 52. The secondary groove 521 is connected to the slot hole 520.

[0101] When the slot hole 520 moves to the point where it is connected to the auxiliary hole, the valve plate 52 blocks the air suction pipe 42 .

[0102] Through the setting of the auxiliary groove 521, after the slot hole 520 rotates past the position of the mounting hole and the mounting hole is blocked, the connection between the auxiliary groove 521 and the slot hole 520 is utilized to complete the connection between the connecting pipe 420 and the auxiliary hole, thereby realizing the functions of the air release mechanism being in the open state and the on-off mechanism being in the connected state. The structure is simple and the practicability is strong.

[0103] A secondary pipe 421 is installed in the secondary hole, and a filter membrane is installed on the secondary pipe 421 .

[0104] By installing the filter membrane through the auxiliary pipe 421, the gas entering the on-off mechanism through the auxiliary hole can be filtered to prevent dust in the gas from entering the on-off mechanism through the suction pipe, which is highly practical.

[0105] Graphite rings 53 are provided inside the support 51 on both sides of the valve plate 52. The graphite rings 53 are used to close the gap between the valve plate 52 and the support 51.

[0106] The graphite ring 53 is provided with through holes at positions corresponding to the mounting hole and the auxiliary hole.

[0107] The gap between the valve plate 52 and the support 51 is blocked by the graphite ring 53, which reduces the precision requirement for manufacturing, prolongs the service life, and has strong practicality.

[0108] 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;

[0109] A cross bar 22 is horizontally arranged on the lifting rod 2, and a slide groove 23 is vertically arranged on the frame.

[0110] 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.

[0111] 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 .

[0112] 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.

[0113] There are multiple lifting rods 2, and a transmission mechanism is provided between each lifting rod 2 and the rotating shaft 1.

[0114] 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 stacked trademark papers 60 in multiple paper storage bins 6, thereby improving work efficiency and having strong practicality.

[0115] like Figure 1 and Figure 2 As shown, the transmission mechanism includes a cam plate 3, a swing rod 31 and a connecting rod 32;

[0116] The cam disc 3 is fixedly mounted on the rotating shaft 1, and a cam ring groove 30 is formed on the side wall of the cam disc 3;

[0117] The middle part of the swing rod 31 is rotatably mounted on the frame, and a roller 310 is rotatably mounted on one end of the swing rod 31 , and the roller 310 is located in the cam ring groove 30 ;

[0118] The connecting rod 32 is rotatably mounted on the free end of the swing rod 31 , and the free end of the connecting rod 32 is rotatably connected to the lifting rod 2 .

[0119] 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, a transmission mechanism is formed by the cam plate 3, the swing rod 31 and the 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.

[0120] A filter 45 is installed on the connecting pipe 420 .

[0121] The external air sucked into the connecting pipe 420 through the suction cup 41 is filtered by the filter 45 to prevent dust in the air from entering the suction mechanism through the connecting pipe 420, which is highly practical.

[0122] In this embodiment, when in use, the external mechanism drives the rotating shaft 1 to rotate, thereby driving the cam plate 3 and the valve plate 52 to rotate;

[0123] During the rotation of the cam plate 3, the lifting rod 2 is driven to move up and down through the transmission mechanism;

[0124] During the rotation of the valve plate 52, the positions of the slot 520 and the auxiliary slot 521 in the support 5 change;

[0125] When the lifting rod 2 rises to the point where the suction cup 41 contacts the trademark paper 60 in the paper bank 6, the slot hole 520 rotates to be connected to the two mounting holes at the same time, and the auxiliary slot 521 is not connected to the auxiliary hole, the on-off mechanism is in a connected state, and the deflation mechanism is in a closed state. At this time, the suction cup 41 is in a negative pressure state under the action of the suction pipe 42, and the trademark paper 60 in the paper bank 6 is adsorbed. Figure 3-Figure 5 As shown;

[0126] After the adsorption is completed, the cam plate 3 and the valve plate 52 continue to rotate, and the transmission mechanism drives the lifting rod 2 to move downward, and the suction cup 41 drives the adsorbed trademark paper 60 to move downward, so that the trademark paper 60 is separated from the paper bank 6. In this process, the valve plate 52 rotates to block the installation hole corresponding to the suction pipe 42, that is, the on-off mechanism is in the off state, such as Figure 6 As shown;

[0127] The rotating shaft 1 continues to rotate until the trademark paper 60 reaches the box mold conveyor belt 61. At this time, the auxiliary groove 521 is connected to the auxiliary hole, the negative pressure state in the suction cup 41 is destroyed, and the suction cup 41 no longer forms adsorption on the trademark paper 60. Figure 7 As shown;

[0128] When the suction cup 41 no longer forms suction on the trademark paper 60, the suction cup 41 is driven by the lifting rod 2 to fall below the box mold conveyor belt 61, and the trademark paper 60 is located on the box mold conveyor belt 61, and the box mold conveyor belt 61 drives the trademark paper 60 to move to the next station;

[0129] When the box mold conveyor belt 61 drives the trademark paper 60 to leave from directly above the suction cup 41, the lifting rod 2 moves upward again under the action of the cam plate 3 and the transmission mechanism, and before the on-off mechanism is reopened, that is, before the two mounting holes are connected again through the slot hole 520, the auxiliary slot 521 is disconnected from the auxiliary hole until the lifting rod 2 rises to the point where the suction cup 41 contacts the trademark paper 60 in the paper bank 6, and the slot hole 520 rotates again to be connected with the two mounting holes at the same time, so that the on-off mechanism is reopened, and the trademark paper 60 in the paper bank 6 is adsorbed for the second time.

[0130] Embodiment two:

[0131] like Figure 8-13 As shown, the only difference between this embodiment and the first embodiment is that the mounting hole corresponding to the connecting pipe 420 is located between the mounting hole corresponding to the air suction pipe 42 and the auxiliary hole;

[0132] When the slot hole 520 moves to the point where it is connected to the auxiliary hole, the valve plate 52 blocks the air suction pipe 42 .

[0133] Apart from this, the rest of the structures are the same as those in the first embodiment.

[0134] By limiting the position of the secondary hole, after the slot hole 520 rotates through the mounting hole position corresponding to the air suction pipe 42 and the mounting hole corresponding to the air suction pipe 42 is blocked, the connection between the connecting pipe 420 and the secondary hole is completed, thereby realizing the functions of the air release mechanism being in an open state and the on-off mechanism being in a connected state. The structure is simple and the practicability is strong.

[0135] In this embodiment, when in use, the external mechanism drives the rotating shaft 1 to rotate, thereby driving the cam plate 3 and the valve plate 52 to rotate;

[0136] During the rotation of the cam plate 3, the lifting rod 2 is driven to move up and down through the transmission mechanism;

[0137] During the rotation of the valve plate 52, the position of the slot 520 in the support 5 changes;

[0138] When the lifting rod 2 rises to the point where the suction cup 41 contacts the trademark paper 60 in the paper bank 6, the slot 520 rotates to be connected to the two mounting holes at the same time and is not connected to the auxiliary hole, the on-off mechanism is in a connected state, and the deflation mechanism is in a closed state. At this time, the suction cup 41 is in a negative pressure state under the action of the suction pipe 42, and the trademark paper 60 in the paper bank 6 is adsorbed. Fig.11 As shown;

[0139] After the adsorption is completed, the cam plate 3 and the valve plate 52 continue to rotate, and the transmission mechanism drives the lifting rod 2 to move downward, and the suction cup 41 drives the adsorbed trademark paper 60 to move downward, so that the trademark paper 60 is separated from the paper bank 6. In this process, the valve plate 52 rotates to block the installation hole corresponding to the suction pipe 42, that is, the on-off mechanism is in the off state, such as Fig.12 As shown;

[0140] The rotating shaft 1 continues to rotate until the trademark paper 60 reaches the box mold conveyor belt 61. At this time, the slot hole 520 is connected with the auxiliary hole and the mounting hole corresponding to the connecting pipe 420 at the same time, and the negative pressure state in the suction cup 41 is destroyed. The suction cup 41 no longer forms adsorption on the trademark paper 60. Fig.13 As shown;

[0141] When the suction cup 41 no longer forms suction on the trademark paper 60, the suction cup 41 is driven by the lifting rod 2 to fall below the box mold conveyor belt 61, and the trademark paper 60 is located on the box mold conveyor belt 61, and the box mold conveyor belt 61 drives the trademark paper 60 to move to the next station;

[0142] When the box mold conveyor belt 61 drives the trademark paper 60 to leave from directly above the suction cup 41, the lifting rod 2 moves upward again under the action of the cam plate 3 and the transmission mechanism, and before the on-off mechanism is reopened, that is, before the two mounting holes are connected again through the slot hole 520, the slot hole 520 is disconnected from the auxiliary hole until the lifting rod 2 rises to the point where the suction cup 41 contacts the trademark paper 60 in the paper bank 6, and the slot hole 520 rotates again to be connected with the two mounting holes at the same time, so that the on-off mechanism is reopened, and the trademark paper 60 in the paper bank 6 is adsorbed for the second time.

[0143] Embodiment three:

[0144] like Figure 14-15 As shown, the only difference between this embodiment and the first embodiment is that 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;

[0145] 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;

[0146] 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;

[0147] 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.

[0148] Apart from this, the rest of the structures are the same as those in the first embodiment.

[0149] The deflation mechanism is formed by the cooperation of the spring 44, the sealing plug 440, the deflation hole and the stopper 441. The elastic force of the spring 44 is used to drive the sealing plug 440 to seal the deflation hole. The stopper 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, thereby connecting the suction cup 41 with the outside atmosphere to achieve automatic deflation. The structure is simple and no additional control mechanism is required. It is very practical.

[0150] In this embodiment, when in use, the external mechanism drives the rotating shaft 1 to rotate, thereby driving the cam plate 3 and the valve plate 52 to rotate;

[0151] During the rotation of the cam plate 3, the lifting rod 2 is driven to move up and down through the transmission mechanism;

[0152] During the rotation of the valve plate 52, the positions of the slot 520 and the auxiliary slot 521 in the support 5 change;

[0153] When the lifting rod 2 rises to the point where the suction cup 41 contacts the trademark paper 60 in the paper bank 6, the slot 520 rotates to be connected with the two mounting holes at the same time, so that the on-off mechanism is in a connected state, the free end of the spring 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 60 in the paper bank 6 is adsorbed;

[0154] After the adsorption is completed, the lifting rod 2 moves downward, and the adsorbed trademark paper 60 is driven downward by the suction cup 41, so that the trademark paper 60 is separated from the paper bank 6, until the trademark paper 60 reaches the box mold conveyor belt 61. At this time, the free end of the reed 44 contacts the stopper 441, and then the sealing plug 440 is separated from the venting hole. At this time, the negative pressure state in the suction cup 41 is destroyed, and the suction cup 41 no longer adsorbs the trademark paper 60;

[0155] At the same time, after the adsorption is completed and before the deflation mechanism is opened, the valve plate 52 is driven by the rotating shaft 1 so that the valve plate 52 blocks the two mounting holes, thereby making the on-off mechanism in a closed state;

[0156] When the suction cup 41 no longer forms suction on the trademark paper 60, the suction cup 41 is driven by the lifting rod 2 to fall below the box mold conveyor belt 61, and the trademark paper 60 is located on the box mold conveyor belt 61, and the box mold conveyor belt 61 drives the trademark paper 60 to move to the next station;

[0157] When the box mold conveyor belt 61 drives the trademark paper 60 to leave from directly above the suction cup 41, the lifting rod 2 moves upward again under the action of the cam plate 3 and the transmission mechanism, and before the slot hole 520 rotates to be connected with the two mounting holes at the same time, so that the on-off mechanism is in a connected state again, the deflation mechanism is closed again, until the lifting rod 2 rises to the suction cup 41 and contacts the trademark paper 60 in the paper library 6, the on-off mechanism is reopened, and the trademark paper 60 in the paper library 6 is adsorbed for the second time.

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.
