Description

Technical Field

[0001] The present application relates to the field of packaging equipment technology, and in particular to a packaging device. Background Art

[0002] Rivet nuts, also known as pull rivet nuts and pull caps, are fastening parts used in various metal sheet and pipe manufacturing industries. Since willow nuts have good firmness and do not require tapping internal threads or welding nuts, they are currently widely used in battery pack sealing, metal sheet connection and other places.

[0003] At present, in order to facilitate the quantitative packaging and sale of willow nuts, batch packaging and packaging of willow nuts are often carried out through packaging devices. In the related art, a packaging device includes a frame, on which a material conveying mechanism for conveying materials, a bagging mechanism for packaging materials into bags, and a boxing mechanism for batch boxing of the packaged bags are sequentially arranged. The material conveying mechanism includes a vibrating plate for screening and conveying willow nuts, a feeding track connecting the discharge end of the vibrating plate and the feed end of the bagging mechanism; the boxing mechanism includes a first conveyor belt arranged below the discharge end of the bagging mechanism, a second conveyor belt arranged below the end of the first conveyor belt, and a plurality of cartons are arranged on the belt surface of the second conveyor belt at intervals. When in use, the bagging mechanism quantitatively packs a batch of willow nuts into bags, and then transports the packaged bagged willow nuts to the second conveyor belt through the first conveyor belt, so that the batch bagged willow nuts are boxed in cartons.

[0004] With respect to the above-mentioned related technologies, during the process of packing and packaging bagged willow nuts, the first conveyor belt throws the bagged willow nuts into the cartons on the second conveyor belt. The bagged willow nuts in the thrown state are arranged rather messily in the carton. The bagged willow nuts thrown into the carton are often piled up in a scattered tower shape inside the carton, making it difficult to fill the cartons on the second conveyor belt with bagged willow nuts more fully, so there is room for improvement. Summary of the invention

[0005] In order to improve the problem that it is difficult to fill bagged willow nuts fully in a carton, the present application provides a packaging device.

[0006] The packaging device provided in this application adopts the following technical solution:

[0007] A packaging device comprises a frame, on which a material conveying mechanism and a bagging mechanism are sequentially arranged, a conveyor belt is arranged on the frame below the discharge port of the bagging mechanism, a slide rail is arranged on the frame at the discharge end of the conveyor belt, a receiving tray is slidably arranged on the slide rail in a direction close to or away from the discharge port of the conveyor belt; a conveyor belt for conveying packaging boxes is arranged on the frame below the end of the slide rail away from the conveyor belt; a driving mechanism for driving the receiving tray to slide back and forth and flattening the surface of the bagged material on the upper end of the receiving tray is arranged on the frame; an opening is opened on the upper surface of the receiving tray, a placement plate for closing or opening the opening is arranged on the receiving tray at the opening, and an adjusting component is arranged on the receiving tray for driving the placement plate to open the opening when the receiving tray moves to just above the conveyor belt.

[0008] By adopting the above technical solution, during the packaging process of rivet nuts, the packaged packaging bags are transported along the conveyor belt to the placement plate of the receiving tray, and then the driving mechanism drives the receiving tray to move close to the conveyor belt, and presses the bulk rivet nuts in the packaging bag during the transportation process to improve the distribution uniformity of the rivet nuts inside the packaging bag. When the receiving tray moves to the top of the conveyor belt, the adjustment component drives the placement plate to open the opening, so that the packaging bag falls vertically into the packaging box on the conveyor belt, so as to realize the neat stacking of the packaging bag in the packaging box, which is convenient for filling the bagged rivet nuts in the carton more fully.

[0009] Optionally, the adjustment component includes a driving shaft rotatably set on the placement plate, a driving motor set on the placement plate and used to drive the driving shaft to rotate, a first gear fixedly sleeved on the circumference of the driving shaft, a rotating shaft rotatably set on the placement plate, a second gear fixedly sleeved on the circumference of the rotating shaft and meshing with the first gear, and the side surface of one end of the placement plate is fixedly connected to the circumference of the rotating shaft.

[0010] By adopting the above technical solution, during the operation of the device, the driving motor drives the first gear to rotate through the driving shaft, and then the first gear drives the second gear to rotate, and the rotating second gear drives the placement plate to rotate through the rotating shaft, so that the rotating placement plate can be adjusted to a closed or open state.

[0011] Optionally, the driving mechanism includes a mounting plate slidably disposed on the frame, and a driving member disposed on the frame and used for driving the mounting plate to move in a direction close to or away from a receiving tray; a positioning plate is movably disposed on the upper end of the receiving tray on a side close to the conveyor belt, and a pulling member elastically connecting the two is disposed between the lower end of the receiving tray on a side close to the conveyor belt and the frame, an adjusting member for driving the positioning plate to be raised and lowered is disposed on the receiving tray, and a hook pulling member for hooking and pulling the positioning plate is disposed on the mounting plate.

[0012] By adopting the above technical solution, after the packaging bag is placed on the placement plate, the driving member drives the installation plate to approach the receiving tray, and then the positioning plate on the receiving tray is hooked and pulled by the hook pull member; then the driving member drives the installation plate to move in the direction toward the conveyor belt, thereby driving the receiving tray to move above the conveyor belt. After the adjustment component drives the placement plate to open the opening so that the packaging bag falls into the packaging box, the adjustment member drives the positioning plate to disengage from the hook pull member, and then the receiving tray is pulled to the bottom of the conveyor belt under the restoring force of the pulling member, so that the receiving tray can receive the next packaging bag.

[0013] Optionally, the hook puller includes a pendulum rotatably arranged on a side of the mounting plate away from the conveyor belt, the rotation axis of the pendulum is perpendicular to the movement direction of the receiving plate, and the length of the pendulum is greater than the distance between the rotation connection of the pendulum and the upper end surface of the packaging bag in the vertical direction, and less than the maximum distance between the rotation connection of the pendulum and the upper end surface of the positioning plate in the vertical direction.

[0014] By adopting the above technical solution, in the process of the driving member driving the mounting plate to move over the receiving tray, since the length of the pendulum is greater than the distance between the rotating connection of the pendulum and the upper end surface of the packaging bag in the vertical direction, when the pendulum moves over the receiving tray, the pendulum rotates into an inclined state under the lifting of the upper surface of the packaging bag, so that the pendulum moves through the surface of the packaging bag; after the driving member drives the mounting plate to move over the receiving tray, the receiving tray and the packaging bag no longer lift the pendulum, and at this time the pendulum freely hangs on the side of the receiving tray close to the conveyor belt, and then the driving member drives the mounting plate away from the conveyor belt. Since at this time one side of the pendulum is blocked by the mounting plate and the opposite side is blocked by the positioning plate, when the driving member drives the mounting plate away from the conveyor belt, the pendulum drives the receiving tray to move synchronously, thereby realizing the position adjustment of the receiving tray.

[0015] Optionally, the pendulum includes a rotating arm portion rotatably mounted on a mounting plate, a supporting rod portion fixedly mounted on a movable end of the rotating arm portion, and a pressing roller portion rotatably sleeved on a circumference of the supporting rod portion and used for rolling a surface layer of the bagged material.

[0016] By adopting the above technical solution, when the pendulum moves over the receiving plate, the rolling part thereon rolls the surface of the bagged material under the action of gravity, so that the rivet nuts in the packaging bag are spread more evenly in the packaging bag, which facilitates the subsequent uniform stacking of the packaging bag in the carton.

[0017] Optionally, the adjusting member includes a slider which is slidably set on the placing plate along the length direction of the driving shaft, the slider is provided with a threaded hole for the driving shaft thread to pass through, the upper end face of the slider is an inclined surface, and the inclined surface is inclined upward along the direction from the conveyor belt to the slide rail, the positioning plate is slidably set on the receiving plate along the height direction, and the inclined surface is slidably fitted with the bottom surface of the positioning plate.

[0018] By adopting the above technical solution, when the rotating driving shaft drives the placement plate to open the opening through the gear set, the driving shaft also drives the slider to slide in a directional manner away from the positioning plate, so that the positioning plate supported by the inclined surface of the slider gradually descends. After the packaging bag at the opening falls out along the opening, the continuously running driving shaft continues to drive the slider to move, so that the positioning plate continues to descend; and when the vertical distance between the upper end surface of the positioning plate and the highest point of the pendulum is equal to or less than the arm length of the pendulum, the positioning plate no longer blocks the pendulum, so that the pendulum is separated from the positioning plate; then the pulling member pulls the receiving tray back to its original position, and the driving motor drives the driving shaft to rotate in the opposite direction, so that the receiving tray is reset to transfer the next packaging bag.

[0019] Optionally, the mounting plate is provided with a push assembly for pushing the packaging bag onto the upper end surface of the placement plate in a direction toward the conveyor belt.

[0020] By adopting the above technical solution, the provided horizontal push assembly can quickly push the packaging bag to a predetermined position at the upper end of the placement plate, so as to improve the stacking accuracy of the packaging bag in the carton.

[0021] Optionally, the push assembly includes an extension plate arranged at the lower end of the mounting plate, a cross bar elastically connected to the extension plate on one side close to the receiving tray, and a push plate that can be raised and lowered on the cross bar, the bottom surface of the push plate slidingly fits with the upper end surface of the receiving tray, the upper end surface of the receiving tray is provided with a positioning groove for the push plate to sink, and the inner wall of the positioning groove is in the shape of an arc.

[0022] By adopting the above technical solution, during the movement of the mounting plate, the push plate moves along and approaches the receiving tray, so that the push plate can directionally push the packaging bag on the receiving plate; after the packaging bag is pushed to the preset position on the placement plate, the push plate moves just above the positioning groove. At this time, the push plate, which is no longer supported by the upper end surface of the receiving tray, slides into the positioning groove, and the movement of the push plate is limited by the inner wall of the positioning groove, thereby completing the precise pushing of the packaging bag.

[0023] Optionally, a notch is provided at the bottom of the push plate, a vertical pole is vertically fixed to the top wall of the push plate in the notch, a through hole is provided on the cross bar for the vertical pole to pass through, a limiting ring is fixed at the lower end of the vertical pole, and the top surface of the limiting ring can be detachably fitted to the bottom surface of the cross bar.

[0024] By adopting the above technical solution, the vertical rod and the limiting ring limit the stable orientation of the push plate on the cross bar, thereby realizing the sliding setting of the push plate in the height direction on the cross bar and making it difficult for the push plate to loosen from the cross bar.

[0025] Optionally, two guide plates are fixedly provided at intervals on one side of the receiving tray close to the conveyor belt, the two guide plates extend to the upper surface of the conveyor belt from one end away from the receiving tray, and the spacing between the two guide plates gradually decreases along the direction from the conveyor belt to the receiving tray.

[0026] By adopting the above technical solution, during the conveyor belt conveying the packaging bag, the packaging bag is guided by the two guide plates to achieve position correction of the packaging bag, so that the packaging plate falls into the middle position of the receiving tray more accurately.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The driving mechanism drives the receiving tray holding the packaging bag to move closer to the conveyor belt, and presses the bulk rivet nuts in the packaging bag during the conveying process. When the receiving tray moves to the top of the conveyor belt, the adjusting component drives the placement plate to open the opening, so that the packaging bag falls vertically into the packaging box on the conveyor belt, so that the packaging bag is neatly stacked in the packaging box, which is convenient for filling the bagged nuts in the carton with full filling;

[0029] 2. When the pendulum moves over the receiving tray, the rolling part on it rolls the surface of the bagged material under the action of gravity, so that the rivet nuts in the packaging bag are spread more evenly in the packaging bag, which is convenient for the subsequent uniform stacking of the packaging bag in the carton;

[0030] 3. During the movement of the mounting plate, the push plate moves along with it and pushes the packaging bag on the placement plate. After the packaging bag is pushed to the preset position on the placement plate, the push plate is directly above the positioning groove. At this time, the push plate, which is no longer supported by the upper end surface of the receiving tray, slides into the positioning groove, thereby limiting the movement of the push plate through the inner wall of the positioning groove, thereby completing the precise pushing of the packaging bag.

[0039] The following is combined with Figure 1-7 This application is described in further detail.

[0040] The present application embodiment discloses a packaging device. Figure 1 and Figure 2 The packaging device includes a frame 1, on which a material conveying mechanism and a bagging mechanism (not shown) are sequentially arranged, a conveyor belt 11 is arranged on the frame 1 below the discharge port of the bagging mechanism, a slide rail 12 is arranged on the frame 1 at the discharge end of the conveyor belt 11, and a receiving tray 2 is slidably arranged on the slide rail 12 in a direction close to or away from the discharge port of the conveyor belt 11. The material conveying mechanism and the bagging mechanism are prior art and will not be described in detail here.

[0041] A conveyor belt 13 for conveying packaging boxes is provided below the end of the slide rail 12 away from the conveyor belt 11 on the frame 1; a driving mechanism is also provided on the frame 1 for driving the receiving tray 2 to slide back and forth and pressing the surface of the bagged material on the upper end of the receiving tray 2. The receiving tray 2 is hollow inside, and an opening is provided on its upper surface that penetrates the upper and lower end surfaces. A placement plate 14 for closing or opening the opening is provided at the opening of the receiving tray 2. The receiving tray 2 is provided with an adjustment component 3 for driving the placement plate 14 to open the opening when the receiving tray 2 moves to the top of the conveyor belt 13.

[0042] Reference Figure 1 and Figure 2 In order to realize the position adjustment of the receiving tray 2, the driving mechanism includes a mounting plate 41 slidably arranged on the frame 1 along the conveying direction of the conveyor belt 11, and a driving member 42 arranged on the frame 1 and used to drive the mounting plate 41 to move in a direction close to or away from the receiving tray 2; a positioning plate 43 is provided on the upper end of the receiving tray 2 close to the conveyor belt 11 and can be raised and lowered, and a pulling member 44 is provided between the lower end of the receiving tray 2 close to the conveyor belt 11 and the frame 1 to elastically connect the two, a hook and pull member for hooking the upper end of the positioning plate 43 is provided on the mounting plate 41, and an adjusting member for driving the positioning plate 43 to be raised and lowered is provided on the receiving tray 2.

[0043] Specifically, the driving component 42 can be any one of a linear motor, a cylinder, and a hydraulic cylinder. In this embodiment, the driving component 42 is preferably a linear motor fixed on the frame 1, and one end of the mounting plate 41 is fixed on the slide rail 12 of the linear motor. The linear motor drives the mounting plate 41 to reciprocate along the conveying direction of the conveyor belt 11.

[0044] Specifically, the pulling member 44 can be a spring, an elastic rope, etc. In this embodiment, the pulling member 44 is preferably a spring. A plurality of springs are arranged on the frame 1, and the two ends of the spring in the length direction are connected to the frame 1 and the receiving tray 2.

[0045] Specifically, refer to Figure 3 The hook puller includes a pendulum 45 rotatably arranged on a side of the mounting plate 41 away from the conveyor belt 11, the rotation axis of the pendulum 45 is perpendicular to the moving direction of the receiving tray 2, and the length of the pendulum 45 is greater than the distance between the rotation connection of the pendulum 45 and the upper end surface of the packaging bag in the vertical direction, and less than the maximum distance between the rotation connection of the pendulum 45 and the upper end surface of the positioning plate 43 in the vertical direction.

[0046] Reference Figure 1 In this embodiment, the pendulum 45 includes a rotating arm portion 451 rotatably mounted on the mounting plate 41, a support rod portion 452 fixedly mounted on the movable end of the rotating arm portion 451, and a pressure roller portion 453 rotatably sleeved on the circumference of the support rod portion 452 and used for rolling the surface of the bagged material. Two support rod portions 452 are fixedly arranged on the rotating arm portion 451 at intervals along a direction perpendicular to the conveying direction of the conveyor belt 11, and the pressure roller portions 453 are rotatably sleeved on both support rod portions 452.

[0047] Reference Figure 4 In another embodiment, the support rod 452 is ball-hinged at the lower end of the rotating arm, and two support rods 452 are provided in a direction away from the conveyor belt 11, and the two support rods 452 form a V shape. When the pendulum 45 moves across the surface of the packaging bag, the rollers 453 on the two support rods 452 roll the surface of the packaging bag, so that the rivet nuts in the packaging bag are spread on both sides in a direction away from the rotating arm 451, so that the rivet nuts are evenly spread in the packaging bag.

[0048] After a packaging bag is transferred and placed on the placement plate 14, the driving member 42 drives the mounting plate 41 to move over the receiving tray 2. Since the length of the pendulum 45 is greater than the distance between the rotating connection of the pendulum 45 and the upper end surface of the packaging bag in the vertical direction, when the pendulum 45 moves over the receiving tray 2, the pendulum 45 rotates into an inclined state under the lifting of the upper surface of the packaging bag, so that the pendulum 45 moves through the surface of the packaging bag and rolls and flattens the surface of the packaging bag.

[0049] After the driving member 42 drives the mounting plate 41 to move through the receiving tray 2, the receiving tray 2, the positioning plate 43 and the packaging bag no longer lift the pendulum 45. At this time, the pendulum 45 hangs freely on the side of the receiving tray 2 close to the conveyor belt 11; then the driving member 42 drives the mounting plate 41 away from the conveyor belt 11. At this time, one side of the pendulum 45 is blocked by the mounting plate 41 and the opposite side is blocked by the positioning plate 43. When the driving member 42 drives the mounting plate 41 away from the conveyor belt 11, the pendulum 45 drives the receiving tray 2 to move synchronously, so that the receiving tray 2 moves to be directly above the carton on the conveyor belt 13.

[0050] Reference Figure 1 and Figure 2 When the conveyor belt 11 conveys the packaging bag to the placement plate 14 on the receiving tray 2, the packaging bag may lie crookedly on the placement plate 14; for this reason, two guide plates 15 are fixedly arranged on the side of the receiving tray 2 close to the conveyor belt 11, and the ends of the two guide plates 15 away from the receiving tray 2 extend to the upper surface of the conveyor belt 13. The two guide plates 15 form a guiding space for the packaging bag, and the spacing between the two guide plates 15 gradually decreases along the direction from the conveyor belt 13 to the receiving tray 2. The minimum spacing between the two guide plates 15 is equal to the width of the packaging bag.

[0051] Furthermore, in order to prevent the packaging bags transported by the conveyor belt 11 from partially slipping off the placement plate 14 on the receiving tray 2 due to inertia, a push assembly 5 is provided on the mounting plate 41 for pushing the packaging bags to the upper end surface of the placement plate 14 in the direction toward the conveyor belt 13, so that the packaging bags can be pushed to the center of the upper end surface of the placement plate 14 through the push assembly 5.

[0052] Specifically, refer to Figure 5 The push assembly 5 includes an extension plate 51 arranged at the lower end of the mounting plate 41, a cross bar 52 elastically connected to the extension plate 51 close to the receiving tray 2 through a spring, and a push plate 53 is arranged at the end of the cross bar 52 away from the extension plate 51. The length direction of the push plate 53 is perpendicular to the conveying direction of the conveyor belt 11. The bottom surface of the push plate 53 is in an arc chamfered shape. A notch is opened in the middle of the bottom of the push plate 53, and a vertical rod 54 is vertically fixed to the inner top wall of the notch of the push plate 53.

[0053] The crossbar 52 is provided with a through hole for the vertical bar 54 to pass through, and a limiting ring 55 is fixed at the lower end of the vertical bar 54. The top surface of the limiting ring 55 can be detachably attached to the bottom surface of the crossbar 52. Figure 2 The upper end surface of the receiving tray 2 is provided with a positioning groove 21 for the push plate 53 to sink, and an inner wall of the positioning groove 21 away from the conveyor belt 11 is in an arc shape. In this embodiment, when the spring at the push plate 53 is not subjected to external force, the push plate 53 is located on the side of the pendulum 45 close to the conveyor belt 11. In another embodiment, when the spring at the push plate 53 is not subjected to external force, the push plate 53 is located on the side of the pendulum 45 away from the conveyor belt 11.

[0054] When the driving member 42 drives the mounting plate 41 to move over the receiving tray 2, the arc bottom surface of the push plate 53 first slides and fits with the upper end surface of the receiving tray 2, so that the push plate 53 is pushed by the upper end surface of the receiving tray 2 and moves upward. During the continuous movement of the mounting plate 41, if the side of the packaging bag away from the conveyor belt 11 is located on the placement plate 14, the push plate 53 will approach and push the packaging bag on the receiving tray 2, so that the packaging bag is pushed and moved to the middle of the placement plate 14. After the packaging bag is pushed onto the placement plate 14, the push plate 53 is directly above the positioning groove 21. At this time, the push plate 53, which is no longer supported by the upper end surface of the receiving tray 2, slides into the positioning groove 21, and the movement of the push plate 53 is limited by the inner wall of the positioning groove 21, so that the packaging bag is accurately pushed. Then the driving member 42 continues to drive the mounting plate 41 to move. During this process, the spring at the cross plate is continuously compressed to ensure that the position of the push plate 53 remains unchanged, so that the pendulum 45 moves over the receiving tray 2 and pulls the positioning plate 43.

[0055] 6, in order to realize the falling of materials on the receiving tray 2, the adjusting component 3 includes a driving shaft 31 rotatably arranged on the receiving tray 2, a driving motor 32 arranged on the placement plate 14 and used to drive the driving shaft 31 to rotate, a first gear 33 fixedly sleeved on the circumference of the driving shaft 31, a rotating shaft 34 rotatably arranged on the receiving tray 2, and a second gear 35 fixedly sleeved on the circumference of the rotating shaft 34 and meshing with the first gear 33. The rotation axes of the driving shaft 31, the first gear 33 and the second gear 35 are all consistent with the conveying direction of the conveyor belt 11; the side surface of one end of the placement plate 14 is fixedly connected to the circumference of the rotating shaft 34.

[0056] When in use, the driving motor 32 drives the first gear 33 to rotate through the driving shaft 31, and then the first gear 33 drives the second gear 35 to rotate, and the rotating second gear 35 drives the placement plate 14 to rotate through the rotating shaft 34, so that the rotating placement plate 14 can be adjusted to a closed or open state.

[0057] Reference Figure 7 In another embodiment, another placement plate 14 is rotatably disposed on the receiving tray 2, and another rotating shaft 34 is fixedly disposed on the side of the other placement plate 14 away from the placement plate 14, and a third gear 36 is coaxially fixed to the end of the other rotating shaft 34. A fourth gear 37 is rotatably disposed between the first gear 33 and the third gear 36 on the receiving tray 2, and the fourth gear 37 is respectively meshed with the first gear 33 and the third gear 36, so that the first gear 33, the second gear 35, the third gear 36 and the fourth gear 37 are combined into a gear set. When the driving motor 32 drives the driving shaft 31 to rotate, the rotating driving shaft 31 drives the two placement plates 14 to open and close the openings through the gear set, so that the packaging bags located on the two placement plates 14 can fall smoothly and vertically into the carton.

[0058] In order to separate the pendulum 45 from the positioning plate 43 so that the receiving tray 2 returns to its original position; Figure 6 The adjusting member includes a slider 46 which is slidably arranged on the inner bottom wall of the placing plate 14 along the length direction of the driving shaft 31. The driving shaft 31 is a mounting shaft with a thread on the outer circumference. A threaded hole for the driving shaft 31 to pass through is arranged on one side of the slider 46. The upper end surface of the slider 46 is an inclined surface, which is inclined upward along the direction from the conveyor belt 11 to the slide rail 12. The positioning plate 43 is slidably arranged on the receiving tray 2 along the height direction, and the inclined surface is slidably fitted with the bottom surface of the positioning plate 43.

[0059] In the process of the rotating driving shaft 31 driving the placing plate 14 to open the opening through the gear set, the driving shaft 31 also drives the slider 46 to slide in a directional manner away from the positioning plate 43, so that the positioning plate 43 supported by the inclined surface of the slider 46 gradually descends. After the packaging bag at the opening falls out along the opening, the continuously running driving shaft 31 continues to drive the slider 46 to move, so that the positioning plate 43 continues to descend; and when the vertical distance between the upper end surface of the positioning plate 43 and the highest point of the pendulum 45 is equal to or less than the arm length of the pendulum 45, the positioning plate 43 no longer blocks the pendulum 45, so that the pendulum 45 is separated from the positioning plate 43; then the pulling member 44 pulls the receiving tray 2 back to its original position, and the driving motor 32 drives the driving shaft 31 to rotate in the opposite direction, so that the receiving tray 2 is reset to transfer the next packaging bag.

[0060] The implementation principle of a packaging device in the embodiment of the present application is as follows: during the packaging process of rivet nuts, the rivet nuts quantitatively delivered by the material conveying mechanism are packaged into bags one by one by the bagging mechanism, and then the packaging bags are dropped into the conveyor belt 11 one by one, and are transported along the conveyor belt 11 to the placement plate 14 of the receiving tray 2. Then the driving mechanism drives the receiving tray 2 to move closer to the conveyor belt 13, and during the transportation process, the packaging bag is first pushed to the middle of the placement plate 14 by the push plate 53, and then the bulk rivet nuts in the packaging bag are rolled and flattened by the pendulum 45.

[0061] After the pendulum 45 in the drive mechanism passes over the receiving tray 2, the drive member 42 in the drive mechanism drives the pendulum 45 away from the conveyor belt 11, so as to push the positioning plate 43 on the receiving tray 2 through the pendulum 45, so as to push the receiving tray 2 to the top of the conveyor belt 13. When the receiving tray 2 moves to the top of the conveyor belt 13, the adjustment component 3 first drives the placement plate 14 to rotate, so that the packaging bag on the placement plate 14 falls into the carton, and then under the continuous operation of the adjustment component 3, the adjustment component 3 drives the slider 46 to gradually move away from the positioning plate 43, so that the positioning plate 43 gradually descends, and when the vertical distance between the upper end surface of the positioning plate 43 and the highest point of the pendulum 45 is no longer higher than the arm length of the pendulum 45, the positioning plate 43 no longer blocks the pendulum 45, so that the pendulum 45 is separated from the positioning plate 43; then the pulling member 44 pulls the receiving tray 2 back to its original position, and the adjustment component 3 drives the placement plate 14 to close the opening, so that the receiving tray 2 is reset to transfer the next packaging bag.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
