[0063] The present invention proposes a box pressing mechanism of a cartoning machine, referring to Figures 1 to 3 ,include:

[0064] Mounting frame 100;

[0065] The pressing box assembly 200 is provided on the mounting frame 100. The pressing box assembly 200 includes at least two pressing box parts. The at least two pressing box parts can be relatively close to or far away from each other.

[0066] The press box height adjustment assembly 300 is provided on the mounting frame 100 and connected to the press box assembly 200, and is used to drive the press box assembly 200 to move up and down to adjust the press box height of the press box assembly 200;

[0067] The press box length adjustment assembly 400 is disposed on the mounting frame 100 and connected to the press box assembly 200 , and is used to drive at least two press box members 210 to move closer or farther away from each other to adjust the press box length of the press box assembly 200 .

[0068] The box pressing mechanism of the cartoning machine proposed in the present invention is used to realize the pressing and holding function of the packaging box 10 in the cartoning machine. The cartoning machine involved is a kind of packaging equipment, which is used to put the product into the packaging box 10 to realize the automatic packaging of the product, such as a facial mask cartoning machine. Figure 1 As shown, the packaging box 10 is generally a rectangular parallelepiped or a cube, including a box body 10a and box tongues 10b provided at both ends of the box body 10a. When packaging, the product is first placed in the box body 10a, and then the box tongues 10b are inserted into the box mouth of the box body 10a to seal it, thereby completing the packaging.

[0069] Specifically, the box pressing mechanism of the cartoning machine is mainly composed of a mounting frame 100, a box pressing assembly 200, a box pressing height adjustment assembly 300, and a box pressing length adjustment assembly 400. Among them, the box pressing assembly 200, the box pressing height adjustment assembly 300, and the box pressing length adjustment assembly 400 are all arranged on the mounting frame 100, and can be arranged indirectly or directly, depending on the actual situation. The box pressing mechanism can be connected to other structures on the cartoning machine through the mounting frame 100 to achieve installation on the cartoning machine. The box pressing assembly 200 is used to press and hold the packaging box 10. The box pressing assembly 200 includes at least two box pressing parts, and the at least two box pressing parts can be relatively close to or far away to adapt to the length of the box body 10a of the packaging box 10. There are at least two box pressing parts, that is, as an optional solution, the box pressing parts can be set to two or more. When there are two box pressing parts, the distance between the two box pressing parts can be adjusted so that the two box pressing parts are close to the two ends of the box body 10a of the packaging box 10 and press them; when there are three box pressing parts, the distance between the three box pressing parts can be adjusted so that the two box pressing parts on both sides are close to the two ends of the box body 10a of the packaging box 10 and press them, and the middle box pressing part presses the middle part of the box body 10a of the packaging box 10; when there are other numbers of box pressing parts, they can be set accordingly according to actual conditions, which will not be repeated here. The structural form of the box pressing part can be various, such as Figure 2 As shown, the box pressing member is in the form of a plate body, so as to press the box body 10a of the packaging box 10 through the bottom surface of the plate body. Of course, this is only exemplary and not restrictive.

[0070] Furthermore, the press box height adjustment assembly 300 is used to adjust the press box height of the press box assembly 200, and the press box length adjustment assembly 400 is used to adjust the press box length of the press box assembly 200. The connection relationship between the press box height adjustment assembly 300 and the press box assembly 200, and the press box length adjustment assembly 400 and the press box assembly 200 can be a direct connection or an indirect connection through other structural settings, which can be set according to actual conditions. Taking the press box assembly 200 as an example, which includes two press box parts, the press box height adjustment assembly 300 includes a first motor, a first screw, and a lifting seat. The first screw is vertically arranged, the output shaft of the first motor is connected to one end of the first screw of the first screw, and the lifting seat is connected to the first nut seat on the first screw. The press box length adjustment assembly 400 is arranged on the lifting seat. The press box length adjustment assembly 400 includes a second motor and a second screw. The second screw of the second screw is provided with two second nut seats with opposite thread directions so as to be able to move closer or farther. The second screw is horizontally arranged, the output end of the second motor is connected to one end of the second screw of the second screw, and the two press box parts are respectively connected to the two second nut seats. In this structural setting, the first motor drives the first screw, so that the lifting seat moves and drives the press box assembly 200 to rise and fall as a whole, thereby adjusting the press box height of the press box assembly 200; the second motor drives the second screw, and the two press box parts move closer or farther with the two second nut seats, thereby adjusting the press box length of the press box assembly 200. The above-described structure of the press box height adjustment assembly 300 and the press box length adjustment assembly 400 is only one of many implementation schemes, and other embodiments are possible. It is easy to understand that the press box height adjustment assembly 300 can include one or more power sources to drive the various press box components in the press box assembly 200 in a unified or separate manner; accordingly, the press box length adjustment assembly 400 can also include one or more power units to drive the various press box components in the press box assembly 200 in a unified or separate manner.

[0071] When packaging boxes 10 of different sizes are used for cartoning, the present carton pressing mechanism can drive the carton pressing assembly 200 to move up and down through the carton pressing height adjustment assembly 300, thereby adjusting the carton pressing height of the carton pressing assembly 200 to adapt to the height of the carton 10 for carton pressing. Furthermore, the carton pressing length adjustment assembly 400 can drive at least two carton pressing members to move closer or farther apart, thereby adjusting the carton pressing length of the carton pressing assembly 200 to adapt to the length of the carton 10 for carton pressing. In this way, the carton pressing mechanism of the present cartoning machine can be used to press and hold packaging boxes 10 of different sizes.

[0072] It is easy to understand that when the cartoning machine uses this box pressing mechanism, it can adapt to pressing and holding packaging boxes 10 of different specifications and sizes. Accordingly, the cartoning machine can also adapt to the production and packaging of packaging boxes 10 of different specifications and sizes, thereby achieving one machine for universal use, reducing user production costs, and improving production efficiency.

[0073] In some embodiments, reference Figure 2 and Figure 3 , the press box height adjustment component 300 includes:

[0074] A movable base 310, on which the pressing box assembly 200 is disposed;

[0075] The first driving member 320 is connected to the moving base 310 and is used to drive the moving base 310 to move up and down.

[0076] In this embodiment, the press box height adjustment assembly 300 adopts a structural arrangement of a first driving member 320 and a movable base 310. The press box assembly 200 is arranged on the movable base 310. The first driving member 320 drives the movable base 310 to move up and down, thereby driving the press box assembly 200 to move up and down accordingly, thereby achieving adjustment of the press box height of the press box assembly 200. As an optional solution, the first driving member 320 includes a cylinder, the cylinder body of the cylinder is mounted on the mounting frame 100, the piston rod of the cylinder is vertically arranged and can extend downward or retract upward, and the movable base 310 is connected to the piston rod of the cylinder, that is, the movable base 310 is driven to move up and down by the cylinder. Of course, the first driving member 320 can also adopt other linear drive modules.

[0077] In some embodiments, reference Figure 4 and Figure 5 , the press box height adjustment component 300 also includes:

[0078] The supporting member 330 is provided on the movable base 310 and can move along with the movable base 310;

[0079] The mounting base 340 is movably disposed on one side of the movable base 310;

[0080] A plurality of stoppers 350 are sequentially spaced apart and arranged on the mounting base 340 and are height-adjustable;

[0081] The second driving member 360 is used to drive the mounting seat 340 to move;

[0082] When the mounting base 340 moves, one of the plurality of stoppers 350 is located on the moving path of the resisting member 330 to block the resisting member 330 from moving.

[0083] In the present embodiment, the second driving member 360 drives the mounting base 340 to move so that one of the multiple stoppers 350 is located on the moving path of the resisting member 330. When the box pressing mechanism presses the box, the first driving member 320 drives the mobile base 310, and the resisting member 330 moves downward with the mobile base 310. By being blocked by the stoppers 350 on its moving path, the resisting member 330 and the mobile base 310 cannot continue to move downward, thereby limiting the box pressing height of the box pressing assembly 200. Wherein, the height of the multiple stoppers 350 is adjustable, and the multiple stoppers 350 can be adjusted to different heights, such as 3cm, 4cm, 5cm, etc., so as to adjust the box pressing height when pressing the packaging boxes 10 of different specifications and sizes. As a specific embodiment, the stopper 350 adopts a bolt, and the bolt is threadedly matched with the mounting base 340, and its height position can be adjusted by rotating the bolt. The movement form of the mounting base 340 can be rotation or translation, which is set according to the situation. Taking the case where the mounting base 340 is in a translational motion as an example, the mounting base 340 is a base body having a certain length, and a plurality of stoppers 350 are arranged on the mounting base 340 in a straight line and spaced apart along the length of the mounting base 340. The second drive member 360 can be a combination of a motor and a lead screw, and the mounting base 340 is connected to the nut seat of the lead screw. For example, when the height of the packaging box 10 is 3 cm, the second drive member 360 drives the mounting base 340 to translate a first distance so that the corresponding first stopper 350 is located in the movement path of the abutment 330; when the height of the packaging box 10 is 4 cm, the second drive member 360 drives the mounting base 340 to translate a second distance so that the corresponding second stopper 350 is located in the movement path of the abutment 330. The mounting base 340 is in a rotational motion, which is further described in subsequent embodiments.

[0084] In some embodiments, reference Figure 4 and Figure 5 , the press box height adjustment component 300 also includes:

[0085] A plurality of detection pieces 370 are provided on the mounting base 340 , and each detection piece 340 corresponds to a stopper 350 ;

[0086] a detection pin 380 connected to one of the plurality of detection pieces 370;

[0087] The first proximity switch 391 is located on one side of the mounting base 340 and is used to sense the detection pin 380 and determine that the mounting base 340 is in the reference position when the detection pin 380 is sensed;

[0088] The second proximity switch 392 is used to sense the detection piece 370 and determine the movement position of the mounting base 340 according to the number of times the detection piece 340 is sensed.

[0089] In this embodiment, when the box pressing mechanism stops working, the first driving member 320 drives the movable base 310 to move and reset to the initial position. The second driving member 360 drives the mounting base 340 to move. When the first proximity switch 391 senses the detection pin 380, it is determined that the mounting base 340 is in the reference position. The first proximity switch 391 sends a sensing signal to the controller, which sends a control signal to the second driving member 360, causing the second driving member 360 to stop driving the mounting base 340, thereby returning the mounting base 340 to zero. When the pressing mechanism starts working, the second driving member 360 drives the mounting seat 340 to move from its reference position. During the movement of the mounting seat 340, the second proximity switch 392 sequentially senses the detection piece 370 provided on the mounting seat 340 and sends a sensing signal to the controller. The moving position of the mounting seat 340 is determined according to the number of times the detection piece 370 is sensed. When the mounting seat 340 drives the corresponding stopper 350 to move to the moving path of the supporting member 330, the controller sends a control signal to the second driving member 360, and the second driving member 360 stops driving the mounting seat 340. Specifically, as Figure 5 As shown, the mounting base 340 is provided with eight stoppers 350. The eight stoppers 350 can be set at different heights to correspond to eight different press box adjustment heights. Eight detection plates 370 are also provided, corresponding to each of the eight stoppers 350. The mounting base 340 begins to move from a reference position. When the second proximity switch 392 senses the detection plate 370 once, it indicates that the mounting base 340 is in the reference position and the corresponding first stopper 350 is located in the movement path of the abutment 330. When the second proximity switch 392 senses the detection plate 370 twice, it indicates that the mounting base 340 has moved from the reference position to the next position and the corresponding second stopper 350 has replaced the first stopper 350 in the movement path of the abutment 330, and so on. In other words, each time the second proximity switch 392 senses the detection plate 370, it corresponds to one movement position of the mounting base 340, and thus one press box adjustment height of the press box assembly 200. For example, the press box adjustment height corresponding to the third stopper 350 is 3 cm. If the press box height of the press box assembly 200 needs to be adjusted to 3 cm, the second driving member 360 drives the mounting base 340 to move. When the second proximity switch 392 senses the detection piece 370 three times, the third stopper 350 arrives at the moving path of the supporting member 330 accordingly. The controller can send a control signal to the second driving member 360, and the second driving member 360 stops driving the mounting base 340 to keep the third stopper 350 on the moving path of the supporting member 330, thereby forming a blockage for the supporting member 330, and realizing the adjustment of the press box height of the press box assembly 200 to 3 cm.

[0090] In some embodiments, reference Figure 4 and Figure 5 The mounting base 340 is rotatably disposed on one side of the movable base 310 , a plurality of stoppers 350 are spaced apart and disposed on the periphery of the mounting base 340 , and the second driving member 360 is used to drive the mounting base 340 to rotate.

[0091] In this embodiment, the second driving member 360 drives the mounting base 340 to rotate, causing the multiple stoppers 350 located around the periphery of the mounting base 340 to sequentially reach the movement path of the abutting member 330. Specifically, the mounting base 340 is circular in structure. The second driving member 360 includes a motor. The motor body is fixed to the mounting frame 100. The motor's output shaft extends vertically upward through the mounting frame 100 and is connected to the mounting base 340. Furthermore, a rotating member 380 can be disposed between the mounting base 340 and the mounting frame 100 to enhance the rotational stability of the mounting base 340. The rotating member 380 includes a first annular disc and a second annular disc disposed opposite each other. The motor's output shaft passes through the first and second annular discs to connect to the mounting base 340. Annular grooves are formed on the opposing surfaces of the first and second annular discs, and a plurality of balls are disposed between the annular grooves of the first and second annular discs. The first annular disc is connected to the mounting base 340, and the second annular disc is connected to the mounting frame 100. When the mounting seat 340 rotates, the first annular disc body is driven to rotate, and the balls in the annular groove roll along the annular groove accordingly.

[0092] In some embodiments, reference Figures 6 to 8 , at least two mounting rods 311 are provided on the movable seat 310, and the pressing box assembly 200 includes a first pressing box member 210 and a second pressing box member 220, the first pressing box member 210 is slidably connected to the at least two mounting rods 311, and the second pressing box member 220 is fixedly connected to the at least two mounting rods 311;

[0093] The press box length adjustment assembly 400 includes a third driving member 410 , which is connected to the first press box member 210 and is used to drive the first press box member 210 to move closer to or away from the second press box member 220 .

[0094] In this embodiment, at least two mounting rods 311 are provided on the movable base 310 to mount the first press box member 210 and the second press box member 220. The first press box member 210 is slidably mounted on the at least two mounting rods 311 of the movable base 310, and the second press box member 220 is fixedly mounted on the at least two mounting rods 311 of the movable base 310. The press box length adjustment assembly 400 drives the first press box member 210 to move on the mounting rods 311 via the third driving member 410 so as to move it closer to or away from the second press box member 220, thereby adjusting the distance between the first press box member 210 and the second press box member 220 and adjusting the press box length of the press box assembly 200. The third driving member 410 can have various structural forms, such as a combination structure of a motor and a lead screw, a combination structure of a motor and a gear rack, etc., and can be configured according to actual conditions.

[0095] In some embodiments, reference Figures 6 to 8 The mounting rod 311 is hollow, and the press box length adjustment assembly 400 also includes at least two screw rods 420, each screw rod 420 is rotatably mounted in a mounting rod 311, and the rod wall of the mounting rod 311 is provided with a through guide hole 311a, a nut seat 421 is provided on the screw rod 420, and the nut seat 421 is formed with a connecting portion 421a, and the connecting portion 421a passes through the guide hole 311a and is connected to the first press box component 210, and the third driving component 410 is connected to one end of the screw rod 420.

[0096] In this embodiment, the screw rod 420 is driven to rotate by the third driving member 410, and the nut seat 421 is limited by the guide hole 311a to move on the screw rod 420, that is, the nut seat 421 moves along the mounting rod 311, thereby driving the first pressing box member 210 to move. It is easy to understand that the screw rod 420 rotates in a clockwise or counterclockwise direction, and the nut seat 421 can correspondingly drive the first pressing box member 210 to move closer to or away from the second pressing box member 220. Among them, as an optional solution, the third driving member 410 can adopt a motor, and it can be provided with one motor, one motor correspondingly connected to at least two screw rods, and the motor is driven by a transmission mechanism to drive the at least two screw rods to rotate, or it can be provided with at least two motors, each motor correspondingly connected to a screw rod, and the motor directly drives the screw rod to which it is connected to rotate.

[0097] In some embodiments, the third driving member 410 is a driving motor, and the press box length adjustment assembly 400 further includes a main synchronous wheel 430 and at least two slave synchronous wheels 440;

[0098] The main synchronous wheel 430 is mounted on the output shaft of the driving motor, and each slave synchronous wheel 440 is mounted on one end of the screw 420 . A synchronous belt 450 is sleeved between the main synchronous wheel 430 and at least two slave synchronous wheels 440 .

[0099] In this embodiment, the third drive member 410 is a drive motor that drives the main synchronous pulley 430 to rotate. Under the transmission of the timing belt 450, each of the slave synchronous pulleys 440 rotates accordingly, thereby driving each of the lead screws 420 to rotate. By using a single power source to drive multiple lead screws 420, synchronization is improved and manufacturing costs are reduced.

[0100] In some embodiments, reference Figure 6 , the cartoning machine's box pressing mechanism also includes:

[0101] The press box length detection component 500 is located between the first press box component 210 and the second press box component 220. The press box length detection component 500 includes a third proximity switch 510 and a detection component 520. The third proximity switch 510 is installed on one of the first press box component 210 and the second press box component 220, and the detection component 520 is installed on the other of the first press box component 210 and the second press box component 220. The third proximity switch 510 is used to sense the detection component 520, and when the detection component 520 is sensed, it is determined that the first press box component 210 is in the reference position.

[0102] In this embodiment, when the cartridge pressing mechanism stops operating, the third driving member 410 drives the first cartridge pressing member 210 to move relatively close to the second cartridge pressing member 220, and simultaneously the detection member 520 and the third proximity switch 510 are relatively close. Furthermore, when the third proximity switch 510 senses the detection member 520, it is determined that the first cartridge pressing member 210 is in the reference position. The third proximity switch 510 sends a sensing signal to the controller, which then sends a control signal to the third driving member 410, causing the third driving member 410 to stop driving the first cartridge pressing member 210, thereby returning the position of the first cartridge pressing member 210 to zero.

[0103] In some embodiments, reference Figure 9 , also includes:

[0104] The material guide assembly 600 is provided at one end of the box pressing assembly 200 and is used to guide the packaged items into the packaging box 10 held by the box pressing assembly 200. The material guide assembly 600 includes a first material guide member 610 and a second material guide member 620 that can be relatively close to or away from each other; and

[0105] The material guide width adjustment assembly 700 is provided at one end of the pressing box assembly 200 and connected to the material guide assembly 600 , and is used to drive the first material guide member 610 and the second material guide member 620 to move closer to or farther away from each other to adjust the material guide width of the material guide assembly 600 .

[0106] In this embodiment, when the box pressing mechanism is provided in the cartoning machine, the material guide assembly 600 of the box pressing mechanism corresponds to the loading station of the cartoning machine. At the loading station of the cartoning machine, the material guide assembly 600 is used to guide the pieces to be packaged during the loading process of the packaging box 10, which can prevent the pieces to be packaged from deflecting or moving away, so as to ensure that the pieces to be packaged are accurately placed in the box. Specifically, the material guide assembly 600 defines the moving space of the pieces to be packaged by the first material guide member 610 and the second material guide member 620 that are relatively arranged. The pieces to be packaged move into the box along the defined space of the first material guide member 610 and the second material guide member 620. The structural appearance of the first material guide member 610 and the second material guide member 620 can be the same or different, and can be set according to actual conditions. Figure 9 As shown, the first guide 610 includes a first vertical plate and a horizontal plate connected to the bottom edge of the first vertical plate. The second guide 620 includes a second vertical plate. The spacing between the first and second vertical plates is adapted to the width of the packaged items to prevent them from deflecting or straying during the loading process of the packaging box 10. The horizontal plate supports the movement and transition of the packaged items during the loading process of the packaging box 10. Of course, this is merely exemplary and not restrictive.

[0107] Furthermore, the first material guide 610 and the second material guide 620 can be moved closer or further apart. Specifically, the guide width adjustment assembly 700 is used to drive the first material guide 610 and the second material guide 620 closer or further apart, so that the spacing between the first material guide 610 and the second material guide 620 is adapted to the width of the packaged items. This allows the guide width of the guide assembly 600 to be adjusted, thereby adapting to guiding items of different sizes. The guide width adjustment assembly 700 can have various structural forms. For example, one of the first material guide 610 and the second material guide 620 is fixed, and the other is movable. A corresponding driving power source is provided to provide driving power to the movable material guide. In another example, both the first material guide 610 and the second material guide 620 are movable, and two corresponding driving power sources are provided to provide driving power to each of the two guides, respectively. Furthermore, the specific driving power source used can be selected according to actual conditions.

[0108] In some embodiments, reference Figure 9 The material guide width adjustment assembly 700 includes:

[0109] The movable frame 710 is movably disposed on the second box pressing member 220 , the first material guide member 610 is connected to the movable frame 710 , and the second material guide member 620 is fixed to the second box pressing member 220 ;

[0110] The fourth driving member 720 is used to drive the movable frame 710 to move so that the first material guiding member 610 approaches or moves away from the second material guiding member 620 .

[0111] In this embodiment, the guide width adjustment assembly 700 adopts a structure of a fourth driving member 720 and a movable frame 710, and the movable frame 710 is movably arranged on the second pressing box member 220. The second guide member 620 is fixed to the second pressing box member 220, and the first guide member 610 is connected to the movable frame 710. The movable frame 710 is driven by the fourth driving member 720 to move horizontally, thereby driving the first guide member 610 to move closer to or away from the second guide member 620 accordingly, thereby achieving the adjustment of the guide width. As an optional solution, refer to Figure 9 The fourth driving member 720 adopts a combination structure of a motor and a screw, the motor is connected to one end of the screw, and the movable frame 710 is connected to the nut seat of the screw, that is, the movable frame 710 is driven to move by the combination structure of the motor and the screw.

[0112] In some embodiments, reference Figure 10 , also includes:

[0113] The box opening assembly 800 is disposed on the movable frame 710 and is used to open the box tongue 10b of the packaging box 10. The box opening assembly 800 includes a tongue member 810 and a fifth driving member 820. The tongue member 810 is located on the side of the second box pressing member 220 facing away from the first box pressing member 210. The fifth driving member 820 is used to drive the tongue member 810 to move closer to or away from the second box pressing member 220.

[0114] Among them, the side wall of the tongue piece 810 facing the second box pressing piece 220 is provided with a tongue groove 811 and a guide tongue portion 812 connected to an opening at one end of the tongue groove 811, and the guide tongue portion 812 is used to hold the box tongue 10b of the packaging box 10 and guide it into the tongue groove 811, and the tongue groove 811 holds the box tongue 10b of the packaging box 10 to open it.

[0115] In this embodiment, when the box pressing mechanism is provided in the cartoning machine, the box opening assembly 800 of the box pressing mechanism corresponds to the loading station of the cartoning machine. At the loading station of the cartoning machine, the box opening assembly 800 is used to open the box tongue 10b of the packaging box 10 so that the package to be packaged can be put into the box for packaging. Specifically, when the packaging box 10 is loaded, the box tongue 10b at the feeding end of the packaging box 10 is automatically placed on the guide tongue portion 812 of the tongue member 810, and as the packaging box 10 moves along the packaging direction, at the loading station, the box tongue 10b of the packaging box 10 moves along the guide tongue portion 812 into the tongue groove 811. At this time, the tongue member 810 is driven by the fifth driving member 820 to move close to the second box pressing member 220, so as to drive the box tongue 10b of the packaging box 10 to flip upward, so that the box tongue 10b is opened to the outside of the box opening of the packaging box 10. Among them, the guide tongue portion 812 on the tongue member 810 can be set in a streamlined shape to make the box tongue 10b move smoothly, and the groove length of the tongue groove 811 is greater than the box width of the packaging box 10 of the largest specification size, so as to adapt to packaging boxes 10 of different specifications and sizes. It is easy to understand that when packaging boxes 10 of different specifications and sizes are used for box packing, the position of the box tongue 10b relative to the tongue member 810 is different, so the fifth driving member 820 can be driven and adjusted to make the tongue member 810 adapt to the position of the box tongue 10b of the packaging box 10, which is flexible in use. As an optional solution, refer to Figure 10 The fifth driving member 820 adopts a combination structure of a motor and a lead screw, the motor is connected to one end of the lead screw, and the tongue member 810 is connected to the nut seat of the lead screw, that is, the tongue member 810 is driven to move by the combination structure of the motor and the lead screw.

[0116] In some embodiments, reference Figure 10 and Figure 11 , also includes:

[0117] The box opening detection assembly 900 is provided on the movable frame 710 and is located on the side of the second box pressing member 220 facing away from the tongue member 810. The box opening detection assembly 900 includes a movable connecting frame 910 and a trigger member 920 and a fourth proximity switch 930 provided on the connecting frame 910. The trigger member 920 is rotatable and includes a contact end 921 and a sensing end 922 that are oppositely arranged. The connecting frame 910 is provided with an avoidance opening 911. The trigger member 920 is located between the avoidance opening 911 and the fourth proximity switch 930. The contact end 921 passes through the avoidance opening 911, and the sensing end 922 faces the fourth proximity switch 930.

[0118] The contact end 921 is used to be contacted by the tongue 10b of the packaging box 10 to push the trigger 920 to rotate and make the sensing end 922 approach the fourth proximity switch 930. The fourth proximity switch 930 is used to sense the sensing end 922 and, when sensing the sensing end 922, determine that the tongue 10b of the packaging box 10 is in an open state.

[0119] In this embodiment, the box opening detection assembly 900 is used to detect whether the box tongue 10b of the packaging box 10 is open to ensure that the box loading process proceeds normally. Specifically, when the box opening assembly 800 opens the box tongue 10b of the packaging box 10, the box tongue 10b of the packaging box 10 contacts and squeezes the contact end 921 of the trigger member 920, thereby pushing the trigger member 920 to rotate and causing the sensing end 922 of the trigger member 920 to move upward toward the fourth proximity switch 930. When the fourth proximity switch 930 senses the sensing end 922 of the trigger member 920, it is determined that the box tongue 10b of the packaging box 10 is in the open state. The fourth proximity switch 930 sends a detection signal to the controller, which can then send a control signal to the loading mechanism to execute the subsequent loading process. On the contrary, if the opening assembly fails to open the tongue 10b of the packaging box 10, the fourth proximity switch 930 does not sense the sensing end 922 of the trigger 920, and the controller does not receive the detection signal from the fourth proximity switch 930 indicating that the tongue 10b of the packaging box 10 is successfully opened, the controller can control the alarm mechanism to sound an alarm to remind the user to stop the machine for inspection. Figure 11 As shown, the trigger member 920 can be a V-shaped structure, with the two ends of the trigger member 920 forming its contact end 921 and sensing end 922 respectively. The trigger member 920 is rotatably connected to the connecting frame 910 at the corner position. The contact end 921 of the trigger member 920 is also formed with a bent portion so that it can be carried to the edge of the avoidance opening through its bent portion. As a preferred design, the connecting frame 910 can be driven by the sixth driving member 940, and the trigger member 920 and the fourth proximity switch 930 on the connecting frame 910 can move therewith, thereby adaptively adjusting the detection position according to the box tongue 10b of the packaging box 10. As an alternative, the sixth driving member 940 may include a cylinder, which drives the connecting frame 910 to move.

[0120] In some embodiments, reference Figure 2 and Figure 3 A first tongue guide plate 211 with adjustable height is installed on the side of the first box pressing member 210 facing away from the second box pressing member 220. The first tongue guide plate 211 is used to press or support the box tongue 10b on one side of the packaging box 10; and / or

[0121] A second tongue guide plate 221 with adjustable height is installed on the side of the second box pressing member 220 facing away from the first box pressing member 210 . The second tongue guide plate 221 is used to press or support the box tongue 10 b on the other side of the packaging box 10 .

[0122] In this embodiment, the first tongue guide plate 211 and the second tongue guide plate 221 are used to press or support the box tongues 10b at both ends of the packaging box 10 when it is moved, so as to limit the position of the box tongue 10b within the range of the box opening, making it easier to insert. However, due to different designs of the packaging box 10, the insertion forms of the box tongues 10b at both ends may be different. Figure 1 and Figure 2As shown, when one of the box tongues 10b at both ends of the packaging box 10 is flipped downward for insertion and the other is flipped upward for insertion, the position height of the first tongue guide plate 211 can be relatively lowered to press the box tongue 10b that is flipped upward for insertion by the first tongue guide plate 211, and the position height of the second tongue guide plate 221 can be relatively lowered to support the box tongue 10b that is flipped upward for insertion by the second tongue guide plate 221.
