[0002] At present, in order to improve the convenience of using packaging bags, a hand buckle is installed on the bag surface of some packaging bag products. In the prior art, in order to improve efficiency, an automatic buckle pressing machine is generally used to buckle the hand buckle on the packaging bag. The current automatic buckle pressing machine has a relatively fixed structure. Basically, after loading the bag, the packaging bag is adsorbed to the buckle pressing position, and the male and female buckles are pressed onto the packaging bag through the male buckle feeding mechanism and the female buckle feeding mechanism and the buckle pressing mechanism on both sides, and then transported to the unloading station. The traditional structure has limited accuracy, and the structure that drives the packaging bag to move after loading the bag is basically a conveyor belt. During the loading and moving process, the packaging bag is easy to shift, resulting in inaccurate buckle positions at subsequent stations and a high defective rate. Utility Model Content

DETAILED DESCRIPTION

[0016] like Figure 1 , Figure 2As shown, an automatic buckle pressing device for handle buckles includes a transport platform 5, and a male buckle feeding device 61, a bagging device 1, a female buckle feeding device 62, and a discharge device 4 are arranged along the periphery of the transport platform 5; the transport platform 5 is provided with a circulating transport line and a bag buckle transfer module 8 arranged on the circulating transport line, and the transport platform 5 has a male buckle feeding station 501, a bagging station 502, an alignment and pressing station 503, a female buckle feeding station 504, a buckle pressing station 505 and a bag discharge station 506 distributed along the circulating transport line; the circulating transport line is used to drive the bag buckle transfer module 8 to move cyclically on multiple stations, and the male buckle feeding station 501 is opposite to the male buckle feeding device 61, and is used to transfer the male buckle The buckle 98 is loaded onto the bag buckle transfer module 8; the bag loading station 502 is opposite to the bag loading device 1, and is used to load the packaging bag 9 onto the bag buckle transfer module 8 with the male buckle 98; the alignment and pressing station 503 is used to align and press the packaging bag 9 with the male buckle 98; the female buckle loading station 504 and the female buckle loading device 62 are used to load the female buckle 99 onto the bag buckle transfer module 8 with the male buckle 98 and the packaging bag, and align and install it with the male buckle 98; the pressing station 505 is used to press the female buckle 99 on the bag buckle transfer module 8 with the male buckle 98; the bag unloading station 506 is opposite to the unloading device 4, and is used to unload the packaging bag 9 after pressing the buckle on the bag buckle transfer module 8 onto the unloading device. The embodiment of the utility model adopts a new type of buckle transfer module, combined with the circular transport line on the transport platform, to complete the entire automated buckle process of putting on the male buckle - putting on the packaging bag, aligning and pressing the packaging bag with the male buckle - putting on the female buckle, and docking the male buckle with the female buckle - unloading on the buckle transfer module, which can complete the transportation between various processes and greatly improve efficiency. In addition, the alignment and pressing station is added to the alignment installation of the packaging bag and the male buckle, and the buckle action is added after the male buckle and the female buckle are docked, which greatly improves the accuracy of the entire buckle process and the quality of the buckle.

[0017] In the embodiment of the utility model, Figures 3 to 5As shown, a bag buckle transfer module 8 with a new structure is adopted to cooperate with a transport platform, wherein the specific structure of the bag buckle transfer module 8 is: it includes a transfer base 81, a first movable seat 82 and a second movable seat 83 which are arranged on the base 81 and can slide relative to the base 81, the front end of the first movable seat 82 is connected with a positioning plate 821, and a rod insertion hole 822 is opened on the positioning plate 821, and the front end of the second movable seat 83 is connected with a bag buckle insertion rod 831, and the bag buckle insertion rod 831 can pass through the insertion rod through hole 822 and extend to the front side of the positioning plate 821, the first movable seat 82 can move relative to the second movable seat 83, and when the bag buckle insertion rod 831 passes through the insertion rod through hole 822 and continues to move forward, it can drive the first movable seat 82 to move synchronously, and the positioning plate 821 is also provided with a bag clamping positioning component 86 which can move with the positioning plate 821. Specifically, the buckle transfer module of this scheme can hang the male buckle and the female buckle on it by passing the buckle rod 831 through the through holes in the middle of the male buckle and the female buckle. In the automated buckle process, the second movable seat 83 first drives the buckle rod 831 to move backward, so that the buckle rod 831 retracts to the rear side of the positioning plate 821. At this time, the male buckle loading station moves the male buckle to the rod through hole 822 of the positioning plate, and then moves the second movable seat 83 to move the buckle rod 831 forward and through the rod through hole 822, so that the male buckle naturally falls on the buckle rod 831. At this time, the entire body is driven to move to other stations through the transfer base 81 to complete the buckle.

[0018] In addition, in the present embodiment, the movement of the first movable seat 82 is mainly driven by the second movable seat 83 moving forward. In order to facilitate the automatic reset of the first movable seat 82 after the second movable seat 83 moves backward, an elastic member is also provided on the transfer base 81 to pull the first movable seat 82 toward the transfer base 81.

[0019] The positioning plate 821 of the present embodiment is mainly used to position the packaging bag 9. In order to enable the packaging bag to be clamped on the positioning plate 821, the positioning plate 821 is also provided with a bag clamping positioning component 86 that can move with the positioning plate 821. The bag clamping positioning component 86 is used to clamp the packaging bag on the positioning plate 821.

[0020] Specifically, in this solution, the specific structure of the bag clamping positioning assembly 86 is as follows: it includes a first fixed seat 861 and a second fixed seat 862 arranged on the positioning plate, a first clamping jaw 8611 hinged on the first fixed seat 861, a second clamping jaw 8622 hinged on the second fixed seat 862, and a clamping release assembly 865 for driving the first clamping jaw 8611 and the second clamping jaw 8622 to rotate, and the clamping release assembly 865 synchronously keeps the first clamping jaw 8611 and the second clamping jaw 8622 in a clamped state or a released state, and in the clamped state, the first clamping jaw 8611 and the second clamping jaw 8622 are pressed against the surface of the positioning plate to clamp the packaging bag on the positioning plate. The first clamping jaw and the second clamping jaw on both sides work together to clamp the packaging bag on the bag buckle transfer module, so that the packaging bag is not easy to loosen during the movement of the buckle transfer module, and the clamping state or the release state is adjusted by the clamping release assembly, which is also convenient for releasing the packaging bag when the buckle is cut.

[0021] In the embodiment of the utility model, the first clamping jaw 8611 and the second clamping jaw 8622 can be driven separately, for example, two corresponding sets of clamp release components 865 are provided. Of course, for the convenience of operation, the clamp release component 865 is connected with the first clamping jaw 8611 and the second clamping jaw 8622 and can drive the first clamping jaw 8611 and the second clamping jaw 8622 to rotate synchronously. In the process of releasing or clamping the packaging bag, the first clamping jaw 8611 and the second clamping jaw 8622 only need to be released or clamped synchronously.

[0022] In this solution, the bag clamping and positioning assembly also includes a third fixed seat 863 arranged on the bag buckle transfer module 8, and the clamp release assembly 865 is arranged on the third fixed seat 863 and can move relative to the third fixed seat 863. It has a simple structure and is easy to install. In addition, the clamp release assembly 865 includes a linkage plate 8651 and a driving rod 8652 arranged on both sides of the linkage plate 8651. The driving rods 8652 on both sides are respectively connected to the first clamping jaw 8611 and the second clamping jaw 8622. A sliding assembly is also provided between the linkage plate 8651 and the third fixed seat 863. In this solution, the linkage plate 8651 moves forward and backward to synchronously drive the first clamping jaw 8611 and the second clamping jaw 8622 on both sides to rotate, so as to achieve a release or clamping action.

[0023] In order to make the clamping effect more stable, in this solution, an elastic member can be provided on the third fixing seat 863 to press the linkage plate 8651 so that the first clamping jaw 8611 and the second clamping jaw 8622 are kept in a clamping posture.

[0024] In this solution, the driving rod 8652 is hinged at the rear end of the first clamping jaw 8611, and the first clamping jaw 8611 is also provided with a hinge 866. The first clamping jaw 8611 is hinged to the first fixed seat 861 through the hinge 866, and the hinge end of the hinge 866 and the first clamping jaw 8611 is located between the front end of the first clamping jaw 8611 and the hinge end of the driving rod 8652. Its structure is simple, and through the action of the hinge 866, when the driving rod 8652 is translated, the first clamping jaw 8611 is driven to rotate relative to the first fixed seat. In this solution, when the driving rod 8652 is translated forward, it drives the first clamping jaw 8611 to move toward the positioning plate to maintain the clamping state, and when the driving rod 8652 is translated forward and backward, it drives the first clamping jaw 8611 to move in the opposite direction of the bag positioning plate to switch the release state.

[0025] In order to achieve a better clamping effect, the front end of the first clamping jaw 8611 is a clamping end, and the clamping end has a flat clamping surface. In the clamped state, the clamping surface faces the front end surface of the positioning plate. The flat clamping surface cooperates with the front end surface of the positioning plate to form a good clamping surface. Of course, in order to increase the clamping effect, a soft cushion layer can also be added to the clamping surface, which can also prevent the surface of the packaging bag from being crushed.

[0026] Furthermore, in the embodiment of the utility model, a connecting seat 8311 is further provided between the bag buckle insertion rod 831 and the second movable seat 83. When the bag buckle insertion rod 831 passes through the insertion rod through hole 822 and continues to move forward, the connecting seat 8311 abuts against the rear end of the positioning plate 821 to drive the first movable seat 82 to move. The structure is simple, and when the bag buckle insertion rod 831 moves forward, only one set of driving mechanism is needed to drive the second movable seat to move, so that the first movable seat 82 can move synchronously with the second movable seat 83.

[0027] Specifically, the buckle inserting rod 831 includes a first buckle inserting rod and a second buckle inserting rod, the inserting rod through hole 822 includes a first inserting rod through hole corresponding to the first buckle inserting rod and a second inserting rod through hole corresponding to the second buckle inserting rod, and the first buckle inserting rod and the second buckle inserting rod are both provided with a connecting seat 8311. Of course, the first buckle inserting rod and the second buckle inserting rod of this solution are both detachable structures, which facilitates the replacement of the first buckle inserting rod and the second buckle inserting rod of corresponding shapes and sizes for male and female buckles of different models.

[0028] In addition, in order to facilitate the adjustment of the gap between the first buckle insertion rod and the second buckle insertion rod to adapt to different types of male and female buckles, the width of the first insertion rod through hole is greater than the width of the first buckle insertion rod, and the width of the second insertion rod through hole is greater than the width of the second buckle insertion rod. The connecting seat 8311 can drive the first buckle insertion rod and the second buckle insertion rod to move relative to each other, and the direction of relative movement of the first buckle insertion rod and the second buckle insertion rod is perpendicular to the direction of movement of the second movable seat 83. In this embodiment, the lower side of the connecting seat 8311 is provided with a slider, a sliding seat and other structures to achieve relative movement between the first buckle insertion rod and the second buckle insertion rod. Moreover, in this embodiment, a detachable limiting structure is provided between the connecting seat 8311 and the second movable seat, and the limiting structure is used to fix the distance between the connecting seats on both sides. In this embodiment, a limiting column installed on the second movable seat 83 cooperates with a protrusion on the connecting seat.

[0029] In this solution, in order to keep the second movable seat 83 stationary and prevent displacement when only the first movable seat 82 needs to be moved, a limiting portion 830 is further provided at the rear side of the second movable seat 83. A matching groove is provided on the limiting portion, and when the second movable seat 83 does not need to be moved, the hook-shaped structure can be hooked into the groove of the limiting portion.

[0030] In the embodiment of the utility model, connecting arms 8210 extending to both sides are provided on both sides of the positioning plate 821, and notches 82101 are provided on the lower sides of the connecting arms 8210. The upper sides of the connecting arms 8210 on both sides are used to install the first fixing seat 861 and the second fixing seat 862, so the positions of the first clamping jaw 8611 and the second clamping jaw 8622 are opposite to the connecting arm 8210, and the notches 82101 on the lower side of the connecting arm 8210 are conducive to making way. For example, after clamping the packaging bag, the surface of the packaging bag covers the front side of the notch 82101. At this time, an air nozzle can be provided on the rear side of the notch 82101 to assist in unloading the packaging bag.

[0031] like Figures 6 to 9 The scheme shown in the figure is used for loading through the male buckle loading device 61 at the male buckle loading station 501, and the male buckle loading process is as follows: after the bag buckle transfer module 8 is in place, the limiting part 830 cooperates with the hook, and the hook moves backward, thereby driving the second movable seat 83 to move relative to the first movable seat, so that the bag buckle insertion rod 831 moves backward and retracts into the insertion rod through hole 822 of the positioning plate; after the above-mentioned action, the male buckle loading mechanism drives the single male buckle 98 to move downward, so that the through hole of the male buckle is opposite to the insertion rod through hole 822, and then pushes the limiting part 830 forward through the hook, so that the second movable seat 83 moves forward, and the bag buckle insertion rod 831 passes through the male buckle 98. At this time, the male buckle loading mechanism is reset, and the male buckle 98 is naturally hung on the bag buckle insertion rod 831, thereby realizing the male buckle loading.

[0032] In addition, if Figure 10 to Figure 11 As shown, the bag clamping and positioning assembly 86 of this solution moves backward in the bag loading station through the linkage plate 8651, which can be driven by the driving member on the bag loading device, so that the first clamping jaw 8611 and the second clamping jaw 8622 rotate to the released state, and the packaging bag 9 is adsorbed and driven to be attached to the positioning plate 821. The bag loading is completed, and through the limiting of the bag buckle insertion rod 831 of this solution, the positioning hole on the packaging bag is naturally aligned with the convex column on the male buckle after the bag loading, completing the preliminary positioning assembly.

[0033] like Fig.12 , Fig.13 As shown, specifically, in this scheme, the specific structure of the bag loading device 1 is: it includes a bag loading mechanism, a bag pushing mechanism arranged on the bag loading mechanism, the bag loading mechanism is provided with a bag hanging rod group 122 for hanging the packaging bags 9; the bag pushing mechanism includes a bag pushing frame 21, a bag pushing assembly 22 arranged on the bag pushing frame 21 and a bag suction assembly 23 arranged at the end of the bag pushing frame 21, the bag pushing assembly 22 is used to push the packaging bags 9 along the hanging bag rod group 122 to the end, and the bag suction assembly 23 is used to suck the packaging bags 9 located at the front end of the bag hanging rod group 122; the bag pushing frame 21 is also provided with a bag dividing assembly above the bag hanging rod group 122, and the bag dividing assembly is used to be inserted between the packaging bags to separate the packaging bags and adjust the posture to the posture of the end packaging bags. The embodiment of the utility model hangs multiple packaging bags on the bag loading mechanism, and uses the bag pushing mechanism to realize the displacement of the packaging bags on the bag hanging rod group, and uses the bag suction component to absorb and load the packaging bags when moving to the end, thereby realizing automatic loading of the packaging bags. In addition, during the process of the packaging bags moving to the end, the present solution adds a bag dividing component, so that the bag dividing component part inserted between the packaging bags can straighten the part of the packaging bags above the through hole, so that it is convenient for the packaging bags to be adsorbed during the subsequent bag loading and prevent the bag from sticking, thereby ensuring the efficiency of bag loading.

[0034] In the embodiment of the utility model, the bag pushing assembly 22 includes a bag pushing movable seat 211 that can move along the bag pushing frame 21 and a bag pushing plate 212 that can move up and down and is arranged on the bag pushing movable seat 211, and when the bag pushing plate 212 is located at the uppermost position, the lowermost end of the bag pushing plate 212 is higher than the upper side of the packaging bag 9 hung on the bag hanging rod group 122. The simple structural design can meet the continuous bag pushing work, and the bag pushing assembly 22 mainly pushes the packaging bag at the rear side of the packaging bag on the bag hanging rod group 122. In order to facilitate the forward pushing of the bag pushing assembly 22, after the bag hanging rod group 122 is supplemented with a new batch of packaging bags, the bag pushing plate 212 of the bag hanging rod group 122 can move from the upper side of the packaging bag to the rear side of the packaging bag to keep the bag pushing operation smooth.

[0035] In addition, in order to maintain stability during the bag pushing process, the bag pushing plate 212 includes a first bag pushing plate and a second bag pushing plate, and the first bag pushing plate and the second bag pushing plate are respectively located on both sides of the bag hanging rod group 122 after being moved down. Since the packaging bag is relatively wide, it is equivalent to pushing the rear side of the packaging bag from both sides to make it move forward.

[0036] In this solution, the bag suction assembly 23 includes a suction rod assembly 231 and a driving assembly for driving the suction rod assembly 231 to move. The suction rod assembly 231 is opposite to the end of the bag hanging rod assembly 122. When the packaging bag moves to the end, the suction rod assembly 231 moves toward the packaging bag, naturally sucking the frontmost packaging bag, and resetting the suction rod assembly 231, so that the packaging bag is sucked away, completing the loading.

[0037] In addition, in order to separate the multiple packaging bags at the end so that the frontmost one can be easily adsorbed, the bag suction assembly 23 also includes a bag separation air nozzle 232 arranged on the bag pushing frame 21 and opposite to the end of the bag hanging rod group 122.

[0038] like Figures 16 to 18 As shown, in this scheme, the specific structure of the bag dividing assembly is as follows: the bag dividing assembly is close to the end of the bag hanging rod group 122, and the bag dividing assembly includes a driving member 141 arranged on the bag pushing frame 21, a movable seat 142 arranged on the driving member 141, and a bag dividing lever 143 arranged on the movable seat 142 and extending downward, the driving member 141 is used to drive the movable seat 142 and the bag dividing lever 143 to reciprocate along the bag-up direction; the bag dividing lever 143 is hinged on the movable seat 142, and a limiting portion 1432 is provided on the bag dividing lever 143, the bag dividing lever 143 can rotate relative to the movable seat 142 in the bag-up direction, and after the bag dividing lever 143 is inserted into the gap of the packaging bag, the limiting portion 1432 is used to limit the bag dividing lever 143 from rotating in the direction away from the bag-up direction. During the bag pushing process, the bag dividing lever 143 is inserted between the multiple packaging bags 9 of the bag loading mechanism to separate the packaging bags, and the driving member 141 is used to drive the bag dividing lever 143 forward (in the bag loading direction) so that the bag dividing lever portion inserted between the packaging bags can straighten the portion of the packaging bag above the through hole to adjust the posture of the packaging bag so that it is easy to be adsorbed during the subsequent bag loading and prevent the bag from sticking. In addition, the bag dividing lever 143 of this solution is hinged and cooperated with the limiting part 1432, so that when the driving member 141 drives the bag dividing lever 143 to reset (in the opposite direction of the bag loading direction), the bag dividing lever is pushed open by the upper part of the packaging bag and inserted into the gap between the multiple packaging bags. When the driving member drives the bag dividing lever forward, the limiting part 1432 limits the rotation of the bag dividing lever to straighten the packaging bag located in front of the bag dividing lever.

[0039] Specifically, in this solution, the lower end of the bag dividing lever 143 is an insertion end 1431. The main function of the insertion end 1431 is to extend into the gap between multiple packaging bags, thereby separating multiple packaging bags on the bag hanging assembly into two batches, one batch located at the rear side of the insertion end 1431, and the other batch located at the front side of the insertion end 1431, and the bag dividing lever 143 is used to adjust the posture of the upper end of the batch of packaging bags located at the front side of the insertion end 1431 to straighten the upper side of the packaging bags.

[0040] In the embodiment of the utility model, the insertion end 1431 is a pointed end whose width gradually decreases from top to bottom. This shape is conducive to its insertion into the gap between multiple packaging bags. Specifically, since the upper ends of the multiple packaging bags on the bag hanging rod are easily fitted together, the degree of fitting will also cause larger gaps in some positions. The bag dividing lever 143 of this scheme will naturally return to a hanging posture due to its own weight. In this scheme, the packaging bag on the lower side is pushed by the bag pushing mechanism to move forward relative to the bag dividing lever 143, or the driving member 141 drives the bag dividing lever 143 to move backward. The upper ends of the multiple packaging bags will contact the rear side of the insertion end 1431 and push the insertion end 1431 to rotate. Fig.17 The insertion end 1431 rotates counterclockwise in the middle, so it can be seen that the insertion end 1431 is placed on the upper side of multiple packaging bags, and the insertion end 1431 always maintains a tendency to return to a hanging posture. When encountering a larger gap, the insertion end 1431 will naturally be inserted into the gap, thereby separating multiple packaging bags. The principle is equivalent to the bag dividing lever 143 stroking along the upper sides of multiple packaging bags. When a larger gap is found, the sharper insertion end will naturally be inserted into the gap.

[0041] Specifically, in the embodiment of the utility model, the side of the insertion end 1431 facing the bag loading direction is a straight side surface, which is conducive to straightening the part of the bag on the side located above the through hole 9011 when pushing a batch of bags in front of the bag separation lever 143 to adjust the posture.

[0042] In addition, the side of the insertion end 1431 facing away from the bag-up direction is an inclined side surface, and the inclined side surface and the straight side surface together form an insertion end 1431 whose width gradually decreases from top to bottom. The structure of the inclined side surface is conducive to forming a tip and facilitates the bag-dividing lever 143 to give way.

[0043] In this solution, the limiting portion 1432 is located near the upper side of the bag-dividing lever 143, and when the bag-dividing lever 143 rotates along the hinge until the limiting portion 1432 abuts against the moving seat 142, the bag-dividing lever 143 is limited to continue rotating in this direction. Specifically, the limiting portion 1432 is a protrusion extending from the inner side of the bag-dividing lever 143. It has a simple structure, and is convenient for limiting the backward rotation of the limiting portion 1432 due to the reverse force of the front packaging bag when the driving member 141 drives the limiting portion 1432 to move forward.

[0044] In the embodiment of the utility model, the bag-dividing lever 143 is provided on both sides of the movable seat 142. It keeps the forces on both sides parallel. Of course, multiple bag-dividing levers 143 can also be adjusted and set according to the width of the packaging bag or the through hole 9011.

[0045] In this solution, the movable seat 142 includes a seat body and sidewalls 1421 located on both sides of the seat body and extending backwards, the two bag-dividing levers 143 are respectively hinged on the sidewalls 1421 on both sides, and the limiting parts 1432 on the two bag-dividing levers 143 are both located at the rear side of the sidewalls 1421 and opposite to the corresponding sidewalls 1421. The structure is simple and easy to manufacture.

[0046] In addition, the present solution drives the bag dividing rod 143 to reciprocate through the driving member 141 to assist in adjusting the posture of the packaging bag on the front side. After completion, the bag dividing rod 143 is translated to the front end, and the bag dividing rod 143 is moved backward and reset to be reinserted into the gap between the packaging bags on the original rear side, thereby separating and realizing circulation.

[0047] In the prior art, the through hole 9011 of the packaging bag is generally elliptical or elliptical in shape. When the bag hanging rod is passed through, the outer peripheral surface of the bag hanging rod generally contacts the upper inner wall and the side inner wall of the through hole 9011, which causes the portion of the packaging bag above the through hole 9011 to be easily tilted (such as Fig.19 , 20 and Fig.21 As shown in the left packaging bag, multiple packaging bags in this state will be difficult to separate, resulting in frequent problems such as bag sticking, bag tipping, multiple bags being loaded at one time, or bags not being adsorbed. Figures 19 to 24As shown, in the embodiment of the utility model, bag-supporting guide blocks are additionally provided on the outer periphery of the rod heads of the first hanging rod and the second hanging rod. The bag-supporting guide blocks increase the contact area and angle with the through hole of the packaging bag. When the packaging bag is pushed to the upper bag, it will inevitably move to contact the bag-supporting guide blocks, so that the bag-supporting guide blocks contact the corner position inside the through hole, simulating the effect of pulling the packaging bag from an oblique direction and a side direction, so that the portion of the packaging bag above the through hole can be easily adjusted from a tilted state to a vertical or nearly vertical posture. Specifically, the bag hanging rod group 122 includes at least two first hanging rods 1221 and second hanging rods 1222 arranged side by side and horizontally, and the ends of the first hanging rod 1221 and the second hanging rod 1222 are respectively provided with a first rod head 12211 and a second rod head 12221, and the first hanging rod 1221 and the second hanging rod 1222 are used to hang the packaging bag to be buckled through the through hole 9011 of the packaging bag; in the automatic buckling machine, the packaging bag will be gradually pushed from the rod body of the first hanging rod 1221 and the second hanging rod 1222 to the rod head position through the bag pushing mechanism, and finally be adsorbed at the rod head position. In order to ensure the smooth buckling of the upper bag, it is necessary to ensure that only one packaging bag is adsorbed at a time during adsorption. Therefore, it is very necessary to perform certain separation operations before the packaging bag is adsorbed. The outer peripheries of the first rod head 12211 and the second rod head 12221 are respectively provided with bag-supporting guide blocks 1225 for supporting the packaging bag 9. When the packaging bag 9 moves to the first rod head 12211 and the second rod head 12221, the inner wall of the through hole 9011 of the packaging bag will contact the outer periphery of the bag-supporting guide blocks 1225 to be supported. The bag-supporting guide blocks 1225 increase the contact area and angle with the through hole 9011 of the packaging bag. When the packaging bag is pushed to the upper bag, it will inevitably move to contact with the bag-supporting guide blocks 1225, so that the bag-supporting guide blocks 1225 contact the corner position inside the through hole 9011, simulating the effect of pushing and pulling the packaging bag from the oblique direction and the side direction, so that the part of the packaging bag above the through hole can be easily adjusted from the tilted state to the vertical or nearly vertical posture. Of course, in the embodiment of the utility model, the first hanging rod 1221 and the second hanging rod 1222 can also be processed into an integral hanging rod, that is, the first hanging rod 1221 and the second hanging rod 1222 are an integral structure, and the overall structure is a flat single hanging rod.

[0048] In the embodiment of the utility model, the bag-supporting guide blocks 1225 on the first hanging rod 1221 and the second hanging rod 1222 are both arranged on the outward side of the first rod head 12211 and the second rod head 12221, and the two bag-supporting guide blocks 1225 are arranged at an angle relative to each other. The outer peripheral surfaces of the bag-supporting guide blocks 1225 arranged opposite to each other on both sides jointly form an effect of enlarging the outer diameters of the first rod head 12211 and the second rod head 12221, that is, only when the packaging bag moves to the corresponding position will it be supported by the bag-supporting guide blocks 1225, which has the advantage of facilitating the movement of the packaging bag at the rod body.

[0049] Furthermore, in the embodiment of the utility model, the outer peripheral surface of the bag support guide block 1225 is arc-shaped and faces the corner direction of the packaging bag through hole 9011. This solution mainly adds an outwardly protruding bag support guide block 1225 on the outer periphery of the first rod head 12211 and the second rod head 12221, and faces the corner of the through hole 9011, so that when the packaging bag moves to contact with the bag support guide block 1225, a pull is formed, so that the part of the packaging bag above the through hole is easily adjusted from a tilted state to a vertical or nearly vertical posture.

[0050] In the embodiment of the utility model, the outer peripheral surface of the bag support guide block 1225 is a concave-convex surface, so that when multiple packaging bags move to the bag support guide block 1225, they are naturally separated by the concave-convex surface on the surface thereof, forming a better separation effect.

[0051] Specifically, in this solution, the surface of the bag support guide block 1225 can be provided with a plurality of convex points, or patterns, or grooves and other structures to form an uneven surface, so that the packaging bags will naturally be separated and arranged along the uneven surface.

[0052] In the embodiment of the utility model, the bag support guide block 1225 on the first rod head 12211 and the second rod head 12221 are both detachably connected. The structure is simple and easy to install.

[0053] In addition, in this embodiment, oblique guide structures 12250 are provided on both sides of the bag support guide block 1225, and the oblique guide structures 12250 are inclined along the length direction of the bag hanging rod group 122. Through the oblique guide structures 12250, the packaging bag can smoothly transition to the surface of the bag support guide block 1225 when moving along the length direction of the hanging rod.

[0054] In this solution, in order to form a better supporting effect, the two bag supporting guide blocks 1225 are arranged at an angle relative to each other. The most ideal angle is toward the upper corners on both sides of the through hole of the packaging bag, but in order to facilitate the adaptation of packaging bags of various specifications, the first rod head 12211 and the second rod head 12221 are further connected to the lower side of the adjusting block 1226, and the adjusting block 1226 is provided with connecting positions on both sides, and the first rod head 12211 and the second rod head 12221 are respectively installed with the connecting positions to adjust the relative angle. Its specific structure is: the lower side of the first rod head 12211 and the second rod head 12221 are provided with concave positions for the adjusting block 1226 to be embedded, and the concave positions are provided with connecting holes, and the connecting positions on both sides of the adjusting block 1226 are long holes. In this solution, screws are used as connectors, which are inserted through the long holes and locked into the connection holes on the lower side of the first rod head 12211 or the second rod head 12221 for fixed installation. After the first rod head 12211 or the second rod head 12221 is rotated to a certain angle, the screw connector can be installed obliquely through the long holes, thereby achieving an angle adjustment effect within a certain range, so that more specifications of packaging bags can be adapted for adjustment and use.

[0055] Moreover, the bag hanging rod set 122 also includes a connecting rod 1223, and connecting parts are provided on both sides of the front end of the connecting rod 1223, and the first hanging rod 1221 and the second hanging rod 1222 are both connected to the connecting parts. The connecting rod 1223 is installed side by side with the first hanging rod 1221 and the second hanging rod 1222 on both sides.

[0056] like Figures 13 to 15 As shown, the embodiment of the utility model improves the bag loading structure of the traditional single-group bag hanging assembly, adopts multiple groups of bag hanging assemblies in conjunction with a rotating switching platform, and realizes uninterrupted bag supply on the automatic buckle machine. When the rotating switching platform drives one group of bag hanging assemblies to rotate to the bag loading station for bag supply, the other group of bag hanging assemblies must be in an idle position, so there is enough time to facilitate manual replenishment of packaging bags, and it does not affect the bag supply to the automatic buckle machine, which greatly improves efficiency. Specifically, the bag loading mechanism includes a first frame 10, a rotating switching platform 11 arranged on the first frame 10, a first driving assembly 111 that drives the rotating switching platform 11 to rotate, and at least two groups of bag hanging assemblies 12 arranged on the rotating switching platform 11, the bag hanging assembly 12 is used to hang the packaging bag 9, one side of the first frame 10 is a bag loading station opposite to the bag pushing mechanism, and the rotating switching platform 11 is used to rotate one group of bag hanging assemblies 12 to the bag loading station.

[0057] In the embodiment of the utility model, the present solution drives the bag hanging assembly 12 to rotate by the rotating switching platform 11, ensuring that only one bag hanging rod group 122 is located at the bag loading station, and the rest are naturally rotated out of the bag loading station, at which time the packaging bags to be buckled can be added through their free ends. The structure is simple, and the rotating switching platform 11 is used for rotation switching, and multiple stations are naturally circulated.

[0058] Therefore, in the embodiment of the utility model, the rotating switching platform 11 is utilized to rotate along its own rotation axis to switch the position of the bag hanging components 12 on its circumference. Therefore, the rotation angle of each rotating switching platform 11 can be set according to the number of bag hanging components 12. For example, when there are two rotating switching platforms 11, the two rotating switching platforms 11 are arranged at 180° relative to each other. At this time, the rotating switching platform 11 only needs to rotate 180° each time to switch different bag loading stations at the bag loading station.

[0059] The rotating switching platform 11 is provided with four groups of bag hanging assemblies 12, and the four groups of bag hanging assemblies 12 are evenly distributed along the circumference of the rotating switching platform 11. That is, the four bag hanging assemblies 12 are arranged at 90° intervals, so that the rotating switching platform 11 can be switched each time by rotating 90°, and the three groups of bag hanging assemblies 12 on the outside are in an idle state, which is convenient for manual replenishment of packaging bags to be buckled.

[0060] In this embodiment, the specific structure of the bag hanging assembly 12 is as follows: the bag hanging assembly 12 includes a mounting seat 121 and a bag hanging rod group 122, one end of the bag hanging rod group 122 is connected to the mounting seat 121, and the other end is a free end for the handle through hole 9011 on the packaging bag 9 to pass through.

[0061] In order to make full use of the space, in this embodiment, the bag hanging assembly 12 further includes a positioning block 123 mounted on the mounting seat 121 and extending along the length direction of the bag hanging rod group 122. The positioning block 123 is used to block and limit the initial position of the packaging bag when it is hung, so that the reset bag pushing mechanism can be located at the rear side of all packaging bags, which is relative to the bag loading station. Similarly, it is also convenient for the rotating switching platform 11 to rotate the bag hanging assembly 12 after replenishing materials to the bag loading station to prevent the packaging bag from interfering with the bag pushing mechanism.

[0062] Specifically, in the embodiment of the utility model, the specific structure of the positioning block 123 is as follows: the positioning block 123 is detachably mounted on the lower side of the mounting seat 121, and includes a connecting plate 1231 connected to the mounting seat 121 and a baffle 1232 provided at the end of the connecting plate 1231 and extending downward, and the baffle 1232 and the connecting plate 1231 form an L-shaped positioning block 123. It has a simple structure, is easy to install and use, and the installation position of the connecting plate 1231 can be adjusted according to needs, thereby adjusting the distance of its limit.

[0063] In the embodiment of the utility model, in order to improve the stability of the rotary switching platform 11 after rotation, a positioning component 14 for limiting the rotation of the rotary switching platform 11 is further provided at the bag loading station on the first frame 10. When the rotary switching platform 11 is switched, the positioning component 14 can be further positioned by correspondingly mounting the lower side of the bag hanging assembly 12 on the rotary switching platform 11 to ensure that the movement is in place and the accuracy of subsequent processing is guaranteed.

[0064] Specifically, in this solution, the first embodiment of the positioning component 14 is: the mounting seat 121 partially extends to the outside of the rotating switching platform 11, and the positioning component 14 includes a detection seat 141 arranged on the first frame 10 and a positioning column 142 on the lower side of the extending end of the mounting seat 121, and the detection seat 141 is provided with a detection port for the positioning column 142 to slide into. Through the detection port on the detection seat 141, when the rotating switching platform 11 is switched, the lower side of the corresponding bag hanging assembly 12 is provided with a positioning column 142 extending downward, and when the positioning column 142 slides into the detection port, the system can detect that it has moved into place. Of course, in this solution, the first driving component 111 that drives the rotating switching platform 11 to rotate can use a servo motor, which can drive the rotating switching platform 11 to rotate accurately, and cooperate with the positioning component 14 in this embodiment to achieve an additional positioning guarantee. In this solution, the detection seat 141 can be implemented by infrared detection.

[0065] In this solution, the second embodiment of the positioning component 14 is: a positioning hole is provided on the lower side of the extended end of the mounting seat 121, and the positioning component 14 includes a pin seat provided on the first frame 10 and a positioning pin provided on the pin seat, and the positioning pin can be inserted into the positioning hole. Of course, for the convenience of use, the pin seat can be connected to a cylinder, a motor, etc. to achieve automatic insertion and limiting, so as to prevent displacement caused by vibration during the bagging process, and improve the position accuracy of subsequent processes.

[0066] In addition, the utility model is also convenient for integrated installation. Specifically, the first frame 10 is also provided with a frame mounting column 15 extending upward from the middle of the rotating switching platform 11, and the frame mounting column 15 is used for mounting with the bag pushing mechanism. It has a simple structure and is easy to assemble and use.

[0067] In this embodiment, the male buckle loading guide rail 611 of the male buckle loading device is used to store the male buckle 98, and a male buckle pushing assembly 612 is also provided in the male buckle loading guide rail 611. The female buckle loading guide rail 621 of the female buckle loading device is used to store the female buckle 99, and a female buckle pushing assembly 622 is also provided in the female buckle loading guide rail 621.

[0068] like Figure 25 to Figure 29As shown, in the alignment and pressing station 503, in order to make more reasonable use of space, the male buckle feeding guide rail 611 crosses over the top of the transport platform 5, and the male buckle feeding guide rail 611 is also provided with a bag buckle alignment and pressing assembly opposite to the alignment and pressing station on the transport platform 5. Specifically, the bag buckle alignment and pressing assembly includes a connecting seat 781, a top pressing member 78 provided on the connecting seat 781, and a driving member for driving the top pressing member 78 to press against the surface of the packaging bag 9 equipped with the male buckle 98, and a soft pressing pad 780 is also provided on the front side of the top pressing member 78, and a clearance hole 7801 is provided on the soft pressing pad 780 for the bag buckle insertion rod 831 to penetrate. It adds that after the male buckle and the packaging bag are put on, they are first pressed, so that the convex columns on the male buckle 98 can pass through the positioning holes 901 on the packaging bag 9 one by one, and then the subsequent upper female buckle is pressed together to ensure the accuracy of the pressing.

[0069] This solution uses a soft pressure pad to press against the surface of the packaging bag, and its surface can be deformed by the convex column on the male buckle during the pressing process, and the packaging bag is pressed against the male buckle, so that the positioning hole on the packaging bag that is misaligned with the male buckle convex column can smoothly pass through the convex column, thereby completing the alignment installation. The clearance hole 7801 on the soft pressure pad can allow the bag buckle insertion rod 831 on the bag buckle transfer module 8 to pass through, so that the soft pressure pad can smoothly press against the surface of the packaging bag and press the packaging bag and the male buckle against the positioning plate 821 to complete the assembly.

[0070] Specifically, in this new embodiment, the front end surface of the soft pressure pad 780 is a flat pressing surface, and the clearance hole 7801 runs through the front end of the soft pressure pad 780 to the inside. Since it is made of soft material, when the pressing surface touches the convex column, it will be sunken along with the convex column, forming an effect of covering the outer periphery of the convex column, and its deformation process just presses the positioning buckle on the packaging bag that is not aligned to the convex column.

[0071] In addition, the soft pressure pad 780 can be a silicone pad, a sponge pad, etc., and the soft pressure pad 780 can be detachably mounted on the top pressure member 78. It is convenient to replace it after being worn out for a long time.

[0072] In the embodiment of the utility model, the pressing member 78 includes a pressing movable seat 7821 and a pressing head 7822 disposed at the front end of the pressing movable seat 7821, and the soft pressure pad 780 is connected to the pressing head 7822. Moreover, in this solution, the driving member can be a cylinder. The cylinder realizes reciprocating motion to press the pressing head 7822 onto the packaging bag.

[0073] Moreover, the pressing head 7822 is also provided with a through hole opposite to the clearance hole 7801. Moreover, the pressing movable seat 7821 is a hollow structure. This makes it possible to reduce the thickness of the pressing head 7822 and the soft pressure pad 780, and the bag buckle insertion rod 831 passes through the clearance hole 7801 and directly penetrates into the pressing movable seat 7821, which is also convenient for adapting to the extension length of the bag buckle insertion rod 831.

[0074] In the embodiment of the utility model, the connecting seat 781 includes a bottom plate 7811, connecting side plates 7812 arranged on both sides of the bottom plate 7811, and the inner sides of the connecting side plates 7812 on both sides are also provided with sliding components that cooperate with the pressing movable seat 7821. Its structure is simple, and it is convenient for the pressing movable seat 7821 to move back and forth smoothly.

[0075] Moreover, the present invention can form a U-shaped connecting seat through the bottom plate 7811 and the connecting side plates 7812 on both sides, which can be directly installed on the male buckle feeding device and used in conjunction with the transport platform to achieve reasonable utilization of space layout and simplify the structure.

[0076] like Figure 30 to Figure 33 As shown, in the upper female buckle loading station 504, a loading and pre-assembly mechanism for loading the female buckle onto the transport platform 5 and pre-pressing the female buckle with the male buckle is also provided at the end of the female buckle loading guide rail 621. Specifically, the feeding pre-assembly mechanism includes an installation connection seat 911, a push plate 912 and a guide rod 913 arranged on the installation connection seat 911. The end face of the push plate 912 is provided with an avoidance hole 9121 opposite to the handle hole in the female buckle 99. The guide rod 913 is located on one side of the push plate 912 and is opposite to the avoidance hole 9121 and can pass through the handle hole in the female buckle 99 to hang the female buckle 99; the installation connection seat 911 is also provided with a first driving group 9141 for driving the guide rod 913 to translate and a second driving group 9142 for driving the push plate 912 to translate. The first driving group 9141 is used to drive the guide rod 913 to pass through the avoidance hole 9121 on the push plate 912, and the second driving group 9142 is used to drive the push plate 912 to move along the guide rod 913 and push the female buckle 99 on the guide rod 913 to translate. The bag buckle alignment press-fitting assembly of the embodiment of the utility model adds a pre-assembly operation to initially snap-fit ​​the female buckle 99 and the male buckle 98 after the female buckle 99 is installed, thereby ensuring smooth pressing during the subsequent pressing and reducing the problem of failure of the pressing due to alignment deviation. Moreover, this scheme is suitable for the pressing process of first installing the male buckle, then the packaging bag, and finally the female buckle. The guide rod extends to the bag buckle transfer module and is directly inserted into the bag buckle rod, forming a guide overlap in the female buckle feeding process, which can ensure that the female buckle is smoothly loaded onto the bag buckle rod, and then the female buckle is pushed onto the male buckle to complete pre-pressing with the male buckle while the female buckle is pushed by the push plate. In the embodiment of the utility model, Fig.34As shown, the guide rod 913 is a double-rod structure, and the width of the guide rod 913 is smaller than the gap between the bag buckle rods 831 on the bag buckle transfer module 8. Correspondingly, the avoidance hole 9121 is a double-hole structure, and can be inserted into the bag buckle rod 831. The double-rod structure is conducive to the two rods jointly carrying the female buckle 99, so that the female buckle 99 is not easily displaced to the left and right sides. Moreover, in this solution, the width of the guide rod 913 is less than the gap between the bag buckle rods 831, so that the guide rod 913 can be inserted into the gap between the bag buckle rods 831, thereby forming an uninterrupted path from the female buckle feeding point to the male buckle, ensuring that the female buckle can be smoothly pushed to the male buckle and buckled with it.

[0077] Specifically, if Fig.31 As shown, the mounting connection seat 911 includes a lower bottom plate 9111, connecting side plates 9112 arranged on both sides of the lower bottom plate 9111, the first driving group 9141 and the guide plug rod 913 are arranged on the lower bottom plate 9111, an upper connecting plate 9113 is also arranged on the connecting side plate 9112 above the guide plug rod 913, the second driving group 9142 is arranged at the upper connecting plate 9113, and the push plate 912 is located between the two connecting side plates 9112. It has a simple structure and integrates two sets of driving, which facilitates the movement of the guide plug rod 913 and the push plate 912.

[0078] In an embodiment of the utility model, the female buckle feeding and pre-assembly mechanism is also combined with the female buckle being fed from the female buckle feeding guide rail 621 to the push plate, and the mounting connection seat 911 is also provided with a female buckle feeding seat 921, and the female buckle feeding seat 921 is docked with the female buckle feeding guide rail 621, and the female buckle feeding seat 921 is also provided with a female buckle feeding assembly for moving a single female buckle 99 downward to the front of the lower side push plate 912.

[0079] Specifically, if Fig.32 As shown, the female buckle feeding assembly includes a clamping assembly 922 for clamping a single female buckle 99; and a third driving group for mobilizing the clamping assembly 922 to move up and down. Moreover, the clamping assembly 922 includes a movable plate 9221 and a clamping rod 9222 disposed on the movable plate 9221. The movable plate 9221 is provided with a clamping position 92210 with an opening extending through the lower side, and the clamping rod 9222 is pressed toward the clamping position 92210. The female buckle is fed from the female buckle feeding guide rail 92 to the clamping position 92210, and a single female buckle is pressed in the clamping position 92210 by the clamping rod 9222. At this time, the guide rod 913 is retracted into the avoidance hole 9121 or is located on one side of the push plate 912 so as not to block the female buckle from moving downward. The movable plate 9221 and the clamping rod 9222 are then driven by the third driving group to move downward to the front side of the push plate (such as Fig.33 As shown), the handle hole of the female buckle is aligned with the avoidance hole 9121, and then the guide rod 913 extends out (as shown Fig.34As shown), the third driving group drives the movable plate 9221 and the clamping rod 9222 to move upward and reset through the avoidance hole 9121 and the handle hole of the female buckle. Since the guide rod 913 is inserted in the female buckle, the female buckle is prevented from moving upward with the movable plate 9221, and the female buckle can be loaded to the front side of the push plate (as shown). Fig.35 shown).

[0080] Moreover, the guide rod 913 moves forward to between the two buckle rods 831, and then the push plate moves toward the buckle rod 831 to push the female buckle forward (such as Fig.36 As shown in the figure, and in the process of moving forward, the avoidance hole 9121 on the push plate allows the bag buckle insertion rod 831 to pass through, so that the push plate can push the female buckle into the position of the male buckle to dock with the male buckle. It only needs to control the push plate to push slowly to complete the pre-pressing of the male buckle and the female buckle, so that the convex column on the male buckle can be inserted into the corresponding concave position of the female buckle (as shown in the figure). Fig.37 shown).

[0081] Moreover, if Fig.43 , Fig.44 As shown, the frame corresponding to the male buckle feeding guide rail 611 of this scheme is also provided with an anti-entanglement component for driving the male buckle pushing component 612 to move. Specifically, the anti-entanglement component includes a driving mounting seat 51 installed on the male buckle feeding guide rail 611, a driving member 52 is provided on the driving mounting seat 51, and a driving rope 53 is provided on the output end of the driving member 52. The driving rope 53 is wound around the outer circumference of the output end of the driving member 52 from one side and then wound out from the other side. The driving mounting seat 51 is also provided with a first guide member 551 and a second guide member 552 on both sides of the output end. The first guide member 551 and the second guide member 552 are used to limit the winding side and the winding side of the driving rope 53 to separate the winding section of the driving rope 53 wound on the surface of the output end. A first guide member and a second guide member are added on both sides of the output end of the driving member. The first guide member and the second guide member can effectively separate the winding side and the winding side of the driving rope, thereby separating the winding sections of the driving rope along the surface of the output end, effectively preventing the winding sections from contacting each other, reducing the breakage caused by friction generated by contact during operation, and greatly improving the service life.

[0082] In the prior art, the driving rope is often made of multiple twisted steel wires. In daily use, if the side is often rubbed, it is equivalent to rubbing the surface of the steel wire. If a single steel wire is broken, it is easy to cause the entire driving rope to break. On the feeding device, the driving rope is a ring-shaped whole section, which basically only contacts the surface of the guide wheel. In order to enable the whole section to rotate forward and reverse, it needs to have a section wound around the output end, which is equivalent to winding in from one side of the winding-in end, winding around the surface of the output end, and returning to the winding-in end to wind out from the other side. In the absence of restrictions, the winding-in end and the winding-out end will contact each other.

[0083] In this solution, the side of the winding-in end is the winding-in side, and the side of the winding-out end is the winding-out side. The drive rope is separated on these two sides by the first guide member and the second guide member in the direction perpendicular to the rotation of the drive rope, thereby preventing the winding-in end and the winding-out end from contacting each other.

[0084] In this solution, the first guide member 551 and the second guide member 552 are relatively distributed on both sides of the output end, which is equivalent to the first guide member 551 and the second guide member 552 being arranged on the same plane, which can reduce the influence on the rotation process of the driving rope.

[0085] In addition, in this solution, the first guide member 551 includes a first connecting column 5511 and a first guide wheel 5512 disposed on the upper side of the first connecting column 5511; the second guide member 552 includes a second connecting column 5521 and a second guide wheel 5522 disposed on the upper side of the second connecting column 5521, and the axes of the first guide wheel 5512 and the second guide wheel 5522 are perpendicular to the axis of the output end. Adding the first guide wheel 5512 and the second guide wheel 5522 can adapt to the rotation of the driving rope during the action process and reduce the friction with the surface of the driving rope.

[0086] Specifically, the driving mounting seat 51 includes a bottom plate 511, a mounting plate 512 disposed on the bottom plate 511 and extending upward, the driving member 52 is mounted on the inner side of the mounting plate 512 and the output end extends from the outer side of the mounting plate 512, and one end of the bottom plate 511 extends from the outer side of the mounting plate 512 to form a mounting platform 5110 for mounting the first guide member 551 and the second guide member 552. It has a simple structure, is easy to install, and can form an installation space at the lower side of the feeding device.

[0087] In this solution, in order to adapt to the driving of two sets of pusher assemblies, two sets of the driving members 52 , driving ropes 53 , and first guide members 551 and second guide members 552 are provided on the driving mounting seat 51 .

[0088] like Fig.38 , Fig.39 As shown, in order to ensure further installation and fastening, at the fastening station 505, the bag buckle transfer module 8 moves to the fastening mechanism 79, and the pushing assembly 790 pushes the first movable seat 82 and the second movable seat 83 to move toward the fastening baffle 793, so that the pre-aligned male and female buckles hung on the bag buckle insertion rod 831 are pressed upward to the cushion layer 7931. Through the cushion layer 7931, the male buckle protrusion can be fully fastened with the female buckle groove to realize the fastening of the packaging bag. At this time, the work of pressing the handle buckle on the packaging bag is completed.

[0089] Specifically, at the unloading station 506, there is also an ejection blowing assembly and an adjustable release position. The positioning cover 71 is provided with an ejection arm 72 that can move relative to the positioning cover 71 and an air nozzle 73 arranged at the front end of the ejection arm 72. The positioning cover 71 is also provided with a driving member connected to the ejection arm 72. The ejection arm 72 is used to push the first movable seat 82 of the buckle transfer module 8 forward. The front end of the positioning cover 71 is an open end. The front end of the positioning cover 71 is also provided with a limit adjustment assembly 77 for limiting the bag positioning assembly 86 and releasing it when the first movable seat 82 is pushed forward. The new buckle transfer module of this embodiment is combined with a bag clamping positioning component, and adopts a buckle transfer module on a positioning cover to limit the transport platform, and at the unloading position, the first moving seat is ejected separately by the ejection arm, so that its positioning plate drives the buckled packaging bag to move forward to the position docking with the unloading mechanism, and in the process of the first moving seat driving the packaging bag forward, the bag clamping positioning component on the first moving seat is limited by the limit adjustment component to achieve the release of the packaging bag at a suitable position, thereby ensuring that the unloading of the packaging bag can smoothly fall on the unloading device. In this scheme, the air nozzle 73 is opposite to the notch 82101. Since the packaging bag is positioned on the positioning plate 821, it can be fixed by being clamped or adsorbed, and the surface of the packaging bag is also covered on the front side of the notch 82101. After the fixation on the packaging bag is released, the airflow blown out by the air nozzle 73 on the rear side can pass through the notch 82101 to act on the packaging bag, thereby playing an auxiliary bag unloading effect.

[0090] Therefore, in this solution, when the positioning plate moves forward, the limit adjustment components 77 on both sides can pass through the recessed position above the connecting arm and contact the bag clamping positioning component to release it.

[0091] Furthermore, in this embodiment, the positioning cover 71 includes a top plate 711, a back plate 712 and a front side plate 713, the back plate 712 is connected to the rear side of the top plate 711, the front side plate 713 is connected to the front side of the top plate 711 and extends downward, and the limit adjustment component 77 is arranged on the front side plate 713.

[0092] Specifically, the specific structure of the limit adjustment component 77 is as follows: the limit adjustment component 77 includes a push rod extending toward the rear side, and the end of the push rod is opposite to the linkage plate 8651 of the bag clamping positioning component.

[0093] In order to facilitate the adjustment of the release position, the push rod is movably arranged on the front side plate 713 and its rearward extension length can be adjusted. The push rod in this solution is a screw rod structure, and the front side plate 713 is provided with a screw hole adapted to be installed therewith. Its structure is simple and easy to adjust. In addition, the limit adjustment assembly 77 is provided on both sides of the front side plate 713.

[0094] In this solution, the ejector arm 72 includes a first ejector arm and a second ejector arm that are arranged opposite to each other, and the front ends of the first ejector arm and the second ejector arm are abutting ends, and the air nozzle 73 is arranged on the abutting ends. The positioning cover is used to limit the buckle transfer module on the transport platform, and at the unloading position, the first moving seat is ejected separately by the ejector arm, so that its positioning plate drives the buckled packaging bag to move forward to the position where it docks with the unloading mechanism, and after it is in place, the air nozzle of the ejector arm can blow air to assist the packaging bag to separate from the buckle transfer module.

[0095] In this embodiment, in order to facilitate the ejection of the first movable seat 82, the ejection arm 72 includes a first ejection arm and a second ejection arm that are arranged opposite to each other, and the front ends of the first ejection arm and the second ejection arm are abutting ends, and the air nozzle 73 is arranged on the abutting ends. The two sides work together to facilitate the smooth sliding of the first movable seat, and in this solution, the first ejection arm and the second ejection arm are opposite to the notches 82101 on both sides, and it is sufficient to ensure that the abutting ends are larger than the notches on both sides. In this solution, the first ejection arm and the second ejection arm are both provided with an air path connector that is the same as the air nozzle 73. It has a simple structure and is easy to install and use.

[0096] In this embodiment, a limiting member 74 for limiting the second movable seat 83 is further provided in the positioning cover 71. Specifically, the limiting member 74 is in the shape of an L-shaped inverted hook. In order to keep the second movable seat 83 stationary and prevent displacement when only the first movable seat 82 needs to be moved, a limiting portion 830 is further provided at the rear side of the second movable seat 83. A matching groove is provided on the limiting portion, and when the second movable seat 83 does not need to be moved, the limiting member 74 with a hook structure can be hooked into the groove of the limiting portion.

[0097] During the feeding process, Figure 40 to Figure 42 As shown, the first ejector arm and the second ejector arm are opposite to the rear end of the positioning plate 821, and the limiting portion 830 cooperates with the limiting member 74. During the forward movement of the first ejector arm and the second ejector arm, they contact the rear end of the positioning plate 821, and the air nozzle 73 falls into the notch 82101 and is opposite to the packaging bag 9. At this time, the first ejector arm and the second ejector arm continue to move forward, which will drive the positioning plate 821 and the first movable seat 82 to move forward. At this time, the second movable seat 83 is hooked by the limiting member 74 and remains motionless, so that during the forward movement of the positioning plate 821, the bag buckle rod 831 will be separated from the through hole of the packaging bag. In the process of moving to the linkage plate 8651 to abut against the limiting adjustment component 77 and continue to move, the limiting adjustment component 77 causes the linkage plate 8651 to move backward, thereby causing the first clamping jaw 8611 and the second clamping jaw 8622 to rotate and transform into a released state, which is now the bag lowering position, and then air is blown through the air nozzle, and the air flow enables the packaging bag to be separated from the positioning plate and fall onto the unloading device.

[0098] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
