Description

Technical Field

[0001] This utility model belongs to the field of packaging technology, and in particular relates to a folding and sealing machine for boxes. Background Technology

[0002] In the existing technology, when packaging items with stable structure and elasticity when stacked, such as paper bags, non-woven bags, plastic bags, and cotton, these items are generally packed manually in order to allow the packaging box to hold more items.

[0003] However, when sealing boxes manually, after placing stacked or elastic items into the boxes, it is necessary to manually squeeze the items into the boxes to allow the boxes to hold more items, which undoubtedly greatly reduces packing efficiency.

[0004] Taking paper bags as an example, multiple paper bags are usually stacked and placed into a packaging box for packing. After multiple paper bags are stacked, there will be gaps between adjacent paper bags. After multiple paper bags are placed into the packaging box, in order to make the packaging box able to hold more paper bags, the packing staff will stack the paper bags a certain distance beyond the opening of the packaging box, then press the stacked paper bags tightly, and then press the stacked paper bags into the packaging box to ensure that multiple paper bags do not protrude from the opening of the box. Finally, the lid of the packaging box is closed to seal the packaging box.

[0005] Therefore, it is evident that when sealing boxes manually using existing technologies, workers may need to rest due to fatigue during long working hours, which can affect packing efficiency. Utility Model Content

[0006] The purpose of this invention is to solve the problem of low packing efficiency when using manual methods for packing in the prior art.

[0007] To solve the above problems, this utility model provides a folding and sealing carton machine, including a frame, a conveying component extending along the conveying direction of the packaging carton and disposed on the frame, and a folding component installed on the frame, wherein the folding component is located above the conveying component in the height direction of the frame.

[0008] The folding cover assembly includes a pressing component mounted on the frame and located above the conveying component, which can move along the height direction; a pair of first pushing cover components mounted on the frame and movable along the height and conveying directions; and a pair of second pushing cover components mounted on the frame and movable along the width direction of the frame. The pair of first pushing cover components are located on both sides of the pressing component in the conveying direction, and the pair of second pushing cover components are located on both sides of the pressing component in the width direction.

[0009] When the packaging box is conveyed along the conveying direction to the area below the pressing component, the pressing component moves downward along the height direction to press the items inside the packaging box into a pressing state; a pair of first push-cover components move downward along the height direction and move towards each other in the conveying direction, pushing the first box covers on both sides of the packaging box in the conveying direction to flip to the first closed state; the pressing component moves upward along the height direction to exit the pressing state; a pair of second push-cover components move towards each other in the width direction and push their respective second box covers to flip to the second closed state.

[0010] Using the above technical solution, when sealing a box containing items, the conveying component transports the box to the bottom of the pressing component along the conveying direction. The pressing component then moves downward along the height direction to press the items inside the box, preventing them from protruding from the box opening. Next, a pair of first push-top components move downward along the height direction and towards each other in the conveying direction, pushing the first lids on both sides of the box to the first closed state. The first lids limit the pressed items inside the box. At this point, the pressing component moves upward along the height direction to release the items inside the box, exiting the pressing state. The first lids again limit the items inside the box, reducing the risk of the pressed items popping out of the box opening again. Finally, a pair of second push-top components move towards each other in the width direction, pushing their respective second lids to the second closed state, completing the box packing process.

[0011] Therefore, this folding and sealing machine can pack and package boxes containing items by setting up a pressing component. This allows it to compress items placed inside the box that extend beyond the box opening in the height direction, and then fold the lid to seal the box opening. This process requires no manual operation and greatly improves the packing efficiency.

[0012] In addition, the pressing component ensures that the items inside the box are firmly packed, allowing for easy sealing and thus maximizing the use of the box to hold more items.

[0013] Furthermore, the present invention also discloses a box-sealing machine with a folding lid. The pressing component includes a first driving member mounted on the frame and whose driving end can move along the height direction, and a pressing component that is transmittedly connected to the driving end of the first driving member. When the packaging box is conveyed to the lower part of the pressing component along the conveying direction, the first driving member drives the pressing component to move downward along the height direction to press the items inside the packaging box.

[0014] Using the above technical solution, when the packaging box is conveyed to the bottom of the pressing component along the conveying direction, the first driving component drives the pressing component to move downward along the height direction and press the items inside the packaging box, so that the items are located inside the packaging box, thereby facilitating the first box cover to be flipped to the first closed state by a pair of first push cover components. When the first box cover is flipped, the risk of being blocked by the items is reduced.

[0015] Furthermore, the present invention also discloses a box-sealing machine, which further includes a pair of limiting members that are pulsatorically connected to the driving end of the first driving member; wherein, in the width direction, the pair of limiting members are located on both sides of the pressing member, and each limiting member is located on the outer side of the corresponding edge of the first box cover in the first closed state.

[0016] When the packaging box is conveyed along the conveying direction to the area below the pressing component, the first driving component drives the pressing component and a pair of limiting components to move downward along the height direction to the pressing state that presses the items inside the packaging box; a pair of first push-cover components push the first box cover to flip to the first closed state; a pair of limiting components move upward along the height direction to exit the pressing state; and a pair of second push-cover components push their respective second box covers to flip to the second closed state.

[0017] Using the above technical solution, a pair of limiting members maintain a compressed state, thus limiting the items inside the packaging box and preventing them from protruding from the box opening. Then, a pair of first push-lid members push the first lid to the first closed state. Since the items inside the packaging box do not protrude from the box opening, the first lid is not obstructed during the flipping process, ensuring reliable closing. After the first lid is in the first closed state and has limited the items inside, the pair of limiting members can move upwards in the height direction to exit the compressed state. Then, a pair of second push-lid members push their respective second lids to the second closed state, finally reliably loading the items into the packaging box.

[0018] Furthermore, the present invention also discloses a box-sealing machine with a folding lid. The first driving component includes a driving cylinder mounted on a frame and whose driving end can move along the height direction, and a base plate fixedly mounted on the driving end of the driving cylinder. On the side of the base plate away from the driving cylinder, a pair of telescopic cylinders whose driving ends can move along the height direction are arranged at intervals along the conveying direction. The pressing component includes a pair of pressing plates respectively arranged on the driving ends of the pair of telescopic cylinders.

[0019] Furthermore, in the width direction, one end of each limiting member is mounted to the substrate, and the other end extends along the height direction and is located between the corresponding lower pressure plate side and the second push cover member in the width direction.

[0020] Using the above technical solution, when the packaging box is conveyed to the bottom of the pressing component along the conveying direction, the base plate can be driven to move downward along the height direction by the driving cylinder, so that a pair of pressing plates and a pair of limiting components press the items into the packaging box. Since the contact area between the pair of pressing plates and the items contained in the packaging box is large, items that are a certain distance away from the opening of the packaging box can be stably pressed into the packaging box.

[0021] Furthermore, the present invention also discloses a box-sealing machine, wherein each limiting component includes a connecting rod with one end rotatably connected to the base plate about the conveying direction and the other end extending downward along the height direction, a connecting seat rotatably connected to the other end of the connecting rod about the conveying direction, a pair of pressure rods correspondingly disposed on both sides of the connecting seat in the conveying direction and extending away from each other in the conveying direction, and a pair of elastic members correspondingly disposed on both sides of the connecting rod; and, one end of each pressure rod is rotatably connected to the corresponding side of the corresponding connecting seat about the width direction, and one end of each elastic member is fixedly connected to the corresponding side of the corresponding connecting rod, and the other end extends to a part near the connecting rod and is fixedly connected to the corresponding pressure rod.

[0022] Using the above technical solution, when the pair of first box lids are flipped to the first closed state, the drive cylinder drives the base plate to move a pair of limiting members upward along the height direction away from the packaging box. If the pressure rod collides with the first box lid, pressure can be applied to the pressure rod through the first box lid, causing the elastic element to be stretched and deformed. The end of the pressure rod away from the connecting seat in the conveying direction swings downward. At the same time, the connecting seat is pushed by the pressure rod end and will swing the connecting rod around the conveying direction, causing the connecting rod to displace in the width direction. At this time, the connecting rod and the pressure rod are displaced in the width direction, thus separating from the first box lid and realizing the retraction of the pressure rod. During this process, when the pressure rod collides with the first box lid, the pressure rod will avoid the first box lid when under force, thus avoiding the problem of the pressure rod lifting the first box lid again during the upward movement.

[0023] Furthermore, the present invention also discloses a box-sealing machine, which further includes a limiting member fixedly installed in the middle of the substrate and extending toward the conveying assembly along the height direction; and the limiting member includes a mounting seat protruding from the middle of the substrate toward the conveying assembly, and a pair of connecting rods corresponding to a pair of limiting members respectively, one end of each connecting rod being rotatably connected to the side of the mounting seat near the corresponding limiting member around the conveying direction, the other end extending toward the connecting seat of the corresponding limiting member, and being rotatably connected to the corresponding connecting seat around the conveying direction.

[0024] By adopting the above technical solution, when the connecting seat is subjected to the pushing force at one end of the pressure rod and the connecting rod swings around the conveying direction, causing the connecting rod to move in the width direction, the displacement distance of the corresponding connecting rod can be limited by the connecting rod, thereby limiting the displacement of the pressure rod in the width direction. This reduces the risk of the pressure rod moving too far in the width direction, which could squeeze the inner wall of the box and cause damage to the packaging box.

[0025] Furthermore, the present invention also discloses a box-sealing machine with a folding lid. A first guiding mechanism is provided between the substrate and the frame. The first guiding mechanism includes a pair of first guide rods spaced apart on both sides of the drive cylinder in the width direction. The pair of first guide rods extend from the substrate toward the frame in the height direction, and one end of each first guide rod is slidably connected to the substrate, while the other end is fixedly connected to the frame.

[0026] Furthermore, a second guide mechanism is provided between each lower pressure plate and the base plate. The second guide mechanism includes a pair of second guide rods spaced apart on both sides of the telescopic cylinder in the width direction. The pair of second guide rods extend from the base plate toward the lower pressure plate in the height direction, and one end of each second guide rod is fixedly connected to the base plate and the other end is slidably connected to the corresponding lower pressure plate.

[0027] By adopting the above technical solution, a pair of first guide rods can guide and limit the substrate during its movement along the height direction, making the substrate more stable during movement and preventing positional deviation; furthermore, the first guide rods can also improve the synchronicity of the two sides of the substrate in the width direction during movement. Similarly, a second guide rod can guide and limit the lower pressure plate during its movement along the height direction, making the lower pressure plate more stable during movement and preventing positional deviation; furthermore, the second guide rods can also improve the synchronicity of the two sides of the lower pressure plate in the width direction during movement.

[0028] Furthermore, the present invention also discloses a folding and sealing box machine, wherein each first push-top component includes a lifting component mounted on a frame and whose drive end can move along the height direction, a connecting base fixedly mounted on the drive end of the lifting component, a second drive component fixedly mounted on the connecting base and whose drive end can move along the conveying direction, and a first push plate pulsator connected to the drive end of the second drive component.

[0029] A third guide mechanism is provided between the connecting base and the frame. The third guide mechanism includes a pair of third guide rods that are spaced apart on the connecting base in the width direction and are located on both sides of the second drive member. The pair of third guide rods extend from the connecting base plate toward the frame in the height direction, and one end of each third guide rod is fixedly connected to the frame and the other end is slidably connected to the connecting base.

[0030] Furthermore, the pressing component and a pair of limiting components move downward along the height direction to the pressing state that compresses the items inside the packaging box. The lifting component drives the connecting base and moves the second driving component downward along the height direction. The second driving component drives the first push plate to move towards the corresponding first box cover along the conveying direction and pushes the first box cover to flip to the first closed state.

[0031] By adopting the above technical solution, since the lifting component can drive the connecting base to move along the height direction, and the second driving component can drive the first push plate to move, the purpose of adapting to different sized packaging boxes can be achieved by changing the displacement distance of the base in the height direction and the displacement distance of the first push plate. Therefore, this folding and sealing machine also has the advantage of wide applicability.

[0032] Furthermore, the present invention also discloses a folding and sealing box machine, wherein each second push-top component includes a mounting plate mounted on a frame, a third drive component fixedly mounted on the mounting plate, a second push plate driven by the third drive component, and a pair of slide rails symmetrically arranged on the mounting plate and located on both sides of the third drive component in the conveying direction. The pair of slide rails are slidably connected to the mounting plate, and the end of the slide rails near the second push plate in the width direction is fixedly connected to the second push plate.

[0033] When the second push cover component pushes the corresponding second box cover to flip, the third drive component drives the second push plate to move toward the corresponding second box cover along the width direction and pushes the second box cover to flip to the second closed state.

[0034] Using the above technical solution, when it is necessary to flip a pair of second lids of a packaging box to the second closed state, the second push plate is driven by the third driving component to move along the width direction toward the corresponding second lid and push the second lid to flip to the second closed state. Therefore, when the size of the packaging box changes in the width direction, the movement distance of the second push plate driven by the third driving component in the width direction can be changed to achieve the purpose of pushing the second lid. Therefore, this lid-folding and sealing machine can be applied to packaging boxes of different widths and has a wide range of applications.

[0035] Furthermore, an embodiment of the present invention also discloses a box-sealing machine, wherein the conveying assembly includes a support platform extending along the conveying direction and disposed on the frame, and a pair of clamping components extending along the conveying direction and located on both sides of the support platform in the width direction.

[0036] During the conveying of the packaging box, the packaging box is placed on the support platform, and a pair of clamping parts are respectively attached to the corresponding side of the packaging box body.

[0037] By adopting the above technical solution, by setting up a support platform and a pair of clamping components, when the packaging box is conveyed along the conveying direction, the support platform can support the packaging box in the height direction, so that the packaging box can be conveyed stably; the pair of clamping components can limit the packaging box in the width direction, thereby avoiding the risk of the packaging box shifting during the conveying process, and enabling the first and second lids of the packaging box to be accurately flipped by the folding assembly.

[0038] Furthermore, the present invention also discloses a folding and sealing machine, wherein a pair of clamping components are mounted on a frame and can be moved along the width direction, the conveying assembly further includes an adjusting component mounted on the frame and connected to the pair of clamping components in a transmission manner, and a limiting part located below the folding assembly in the height direction is also provided on the frame; wherein, when the packaging box is conveyed to the lower part of the folding assembly along the conveying direction, the limiting part limits the box body on both sides in the width direction and the front side in the conveying direction.

[0039] Using the above technical solution, the spacing between a pair of clamping components in the width direction can be adjusted by adjusting the component, so that the pair of clamping components can adapt to packaging boxes of different sizes. For example, when the size of the packaging box in the width direction decreases, the pair of clamping components can be driven to move towards each other in the width direction by adjusting the component to limit the packaging box.

[0040] In addition, by setting limiting parts, the box body is limited on both sides in the width direction and the front side in the conveying direction, so that the position of the box will not shift when the folding assembly folds the box, and the folding assembly can accurately fold the box.

[0041] Furthermore, the present invention also discloses a folding and sealing machine, wherein the limiting part includes a side limiting component and a front limiting component disposed on the frame; wherein, when the packaging box is conveyed along the conveying direction to the bottom of the folding assembly, the side limiting component limits the box body on both sides in the width direction, and the front limiting component limits the box body on the front side in the conveying direction.

[0042] By adopting the above technical solution, and by setting a front-end limiting component, when the packaging box is conveyed along the conveying direction to the area below the folding assembly, the packaging box can be limited in the conveying direction, avoiding the risk of positional displacement of the packaging box in the conveying direction during the folding process. This allows a pair of first push-lid components to accurately push the first lid of their respective packaging boxes, and the first lids on both sides of the packaging box in the conveying direction can accurately flip to the first closed state. By setting a side-end limiting component, when the packaging box is conveyed along the conveying direction to the area below the folding assembly, the packaging box can be limited in the width direction, avoiding the risk of positional displacement of the packaging box in the width direction during the folding process. This allows a pair of second push-lid components to accurately push the second lid of their respective packaging boxes, and the second lids on both sides of the packaging box in the width direction can accurately flip to the second closed state.

[0043] Furthermore, the present invention also discloses a folding and sealing box machine, which further includes a sealing assembly mounted on a frame and located downstream of the folding assembly, and the sealing assembly is located above the conveying assembly in the height direction; wherein, the sealing assembly includes a mounting frame mounted on the frame that can move in the height direction, and a sealing component mounted on the mounting frame, and the support platform is located directly below the sealing component in the height direction.

[0044] By adopting the above technical solution, when the packaging box is conveyed along the conveying direction to the bottom of the folding assembly, the pair of second box lids can be sealed by adhesive tape through the sealing component, which reduces the risk that the pair of first box lids and the pair of second box lids of the packaging box will be opened again due to the rebound of the items inside the packaging box, making the subsequent transportation of packaging boxes containing items safer and more reliable.

[0070] As described in the background art, when packing by hand, after placing stacked elastic items or items that are elastic on their own into the packaging box, it is necessary to manually squeeze the items into the box so that the packaging box can hold more items. However, in the prior art, when sealing the box manually, the workers may need to rest due to fatigue during long working hours, which will affect the packing efficiency.

[0071] To address the aforementioned problems, this utility model provides a folding and sealing carton machine, comprising a frame, a conveying assembly extending along the conveying direction of the packaging carton and mounted on the frame, and a folding assembly mounted on the frame. The folding assembly includes a pressing component mounted on the frame, located above the conveying assembly and movable along the height direction, a pair of first pushing components mounted on the frame and movable along both the height and conveying directions, and a pair of second pushing components mounted on the frame and movable along the width direction of the frame. When sealing a packaging carton containing items, this folding and sealing carton machine conveys the packaging carton containing items along the conveying direction to the area below the pressing component. Then, the pressing component moves downward along the height direction to press the items inside the packaging carton firmly, preventing the items from protruding from the opening of the packaging carton. Then, the lid is folded to seal the opening of the packaging carton. During this process, no manual operation is required, greatly improving the packing efficiency of the packaging carton.

[0072] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0073] First, the overall structure of this folding and sealing box machine will be explained.

[0074] like Figure 1 As shown, a box-sealing and folding machine includes a frame 1, a conveying assembly 2 extending along the conveying direction L of the packaging box and disposed on the frame 1, and a folding assembly 3 installed on the frame 1, wherein the folding assembly 3 is located above the conveying assembly 2 in the height direction of the frame 1; the conveying assembly 2 conveys the packaging box along the conveying direction L, and the folding assembly 3 folds the packaging box during the process of the packaging box being conveyed by the conveying assembly 2.

[0075] Specifically, the folding cover assembly 3 includes a pressing member 30 mounted on the frame 1, located above the conveying assembly 2 and movable in the height direction; a pair of first push cover members 31 mounted on the frame 1 and movable in the height direction and the conveying direction L; and a pair of second push cover members 32 mounted on the frame 1 and movable in the width direction W of the frame 1. The pair of first push cover members 31 are located on both sides of the pressing member 30 in the conveying direction L, and the pair of second push cover members 32 are located on both sides of the pressing member 30 in the width direction W.

[0076] More specifically, when the packaging box is conveyed along the conveying direction L to the area below the pressing component 30, the pressing component 30 moves downward along the height direction to a pressing state that presses the items inside the packaging box tightly; a pair of first push-cover components 31 move downward along the height direction and move towards each other in the conveying direction L, pushing the first box covers on both sides of the packaging box to flip to the first closed state; the pressing component 30 moves upward along the height direction to exit the pressing state; a pair of second push-cover components 32 move towards each other in the width direction W, and push their respective second box covers to flip to the second closed state.

[0077] It should be understood that when the packaging box is conveyed along the conveying direction L by the conveying component 2, the items inside the packaging box will protrude from the box opening. Therefore, the pair of first box lids and the pair of second box lids of the packaging box are all vertically arranged along the height direction to limit the items that exceed the box opening. In addition, this embodiment is not limited to the type of packaging box, such as cardboard boxes, plastic boxes, etc.

[0078] More specifically, the working principle of this folding and sealing machine is as follows: When sealing a package containing items, the conveying component 2 transports the package containing items to below the pressing component 30 along the conveying direction L. Then, the pressing component 30 moves downward along the height direction to press the items inside the package, so that the items inside the package do not protrude from the opening of the package. Then, a pair of first push-top components 31 move downward along the height direction and move towards each other in the conveying direction L, pushing the package on both sides in the conveying direction L. The first box lid flips to the first closed box state, limiting the compressed items inside the box. At this time, the pressing component 30 moves upward along the height direction to loosen the items inside the box and remove the compressed state. The first box lid limits the items inside the box, thereby reducing the risk of the compressed items popping out of the box opening again. Then, a pair of second push-cover components 32 move towards each other along the width direction W, thereby pushing their respective second box lids to flip to the second closed box state, realizing the box sealing process.

[0079] Therefore, this folding and sealing machine, when packing boxes containing items, uses a pressing component 30 to compress items placed inside the box that protrude from the box opening in the height direction, and then folds the lid to seal the box opening. During this process, the pressing component 30 ensures that the items inside the box are firmly compressed, allowing for smooth sealing. This ensures that more items can be packed into the box without manual operation, greatly improving the packing efficiency.

[0080] Furthermore, such as Figure 3As shown below, the structure and configuration of the folding cover assembly 3 will be further explained.

[0081] Optionally, in one embodiment, the pressing component 30 includes a first driving member 300 mounted on the frame 1 and whose driving end is movable in the height direction, and a pressing component 301 that is pulsatorically connected to the driving end of the first driving member 300.

[0082] Specifically, when the packaging box is conveyed along the conveying direction L to the lower part of the pressing component 30, the first driving component 300 drives the pressing component 301 to move downward along the height direction and press the items inside the packaging box so that the items are located inside the packaging box. This makes it easier to push the corresponding first box lids to the first closed state by a pair of first push-cover components 31. When the first box lids are flipped, the risk of being blocked by the items is reduced.

[0083] Alternatively, in one feasible implementation, such as Figures 4-6 As shown, in order to prevent the items inside the packaging box from popping out of the box again due to the extrusion force between adjacent items caused by their own elasticity or the overlapping and pressing of multiple adjacent items after the pressing component 30 has compressed the items, this box-sealing machine also includes a pair of limiting components 4 that are drivenly connected to the drive end of the first driving component 300. In the width direction W, the pair of limiting components 4 are located on both sides of the pressing component 301, and each limiting component 4 is located on the outer side of the corresponding edge of the first box lid in the first closed state.

[0084] Specifically, when the packaging box is conveyed along the conveying direction L to the area below the pressing component 30, the first driving component 300 drives the pressing component 301 and a pair of limiting components 4 to move downwards along the height direction to a pressing state that presses the items inside the packaging box tightly. The pair of limiting components 4 limit the items in the pressing state inside the packaging box, preventing the items from protruding from the opening of the packaging box. Then, a pair of first push-cover components 31 push the first box cover to flip to the first closed state, ensuring that the first box cover is not blocked when flipping because the items inside the packaging box do not protrude from the opening of the packaging box, thus ensuring that the first box cover can reliably close. After the first box cover flips to the first closed state and limits the items inside the packaging box, the pair of limiting components 4 can move upwards along the height direction to exit the pressing state. Then, a pair of second push-cover components 32 push their respective second box covers to flip to the second closed state, ultimately achieving reliable loading of items into the packaging box.

[0085] Furthermore, it should be understood that when the pair of first box lids on both sides of the packaging box are flipped to the first closed state in the conveying direction L, there is a gap area between them (that is, a clearance area), so that they can avoid each other with the pressing member 301. After the pressing member 301 and the pair of limiting members 4 move downward in the height direction to the pressing state to press the items in the packaging box, if the area pressed by the pressing member 301 is smaller than the gap area between the pair of first box lids, after the pressing member 301 presses the items, the pressing member 301 does not need to move upward in the height direction to exit the pressing state. The pair of limiting members 4 maintain the pressing state and together with the pressing member 301 limit the items in the packaging box, and do not need to move upward in the height direction to exit the pressing state. After the pair of first box lids are flipped to the first closed state, the pressing member 301 and the limiting members 4 then exit the pressing state together.

[0086] Furthermore, if the area pressed by the pressing member 301 is larger than the interval between the pair of first box lids, before the pair of first box lids flip to the first closed state, the pressing member 301 can be moved upward along the height direction to exit the pressing state, but the pair of limiting members 4 remain in the pressing state to limit the items inside the packaging box. After the pair of first box lids flip to the first closed state, the pair of limiting members 4 then exit the pressing state.

[0087] Furthermore, the structure and arrangement of the first driving member 300 and the pressing member 301 of the pressing member 30 are not limited, but are provided as examples.

[0088] Optionally, in one implementation, such as Figure 5 and Figure 6 As shown, the first driving component 300 includes a driving cylinder 302 mounted on the frame 1 and whose driving end can move along the height direction, and a base plate 303 fixedly mounted on the driving end of the driving cylinder 302; a pair of telescopic cylinders 304 whose driving ends can move along the height direction are provided at intervals along the conveying direction L on the side of the base plate 303 away from the driving cylinder 302; and the pressing component 301 includes a pair of pressing plates 305 respectively disposed on the driving ends of the pair of telescopic cylinders 304.

[0089] Furthermore, in the width direction W, one end of each limiting member 4 is mounted to the base plate 303, and the other end extends along the height direction and is located in the width direction W between the side of the corresponding lower pressure plate 305 and the second push cover member 32.

[0090] It is important to understand that there is a gap between the first lids on both sides of the packaging box in the conveying direction L and the box body in the width direction W; that is, there is a gap between the two sides of the first lids in the width direction W and the inner wall of the corresponding packaging box. Taking a cardboard box as an example, the first lid is the short lid of the cardboard box, and the short lid of the cardboard box is generally trapezoidal, which has a gap with the box body. By installing one end of each limiting member 4 to the base plate 303, and the other end extending along the height direction and located in the width direction W between the side of the corresponding lower pressure plate 305 and the second push-cover member 32, it can be realized that the limiting member 4 will not interfere with the second push-cover member 32 when it moves upward.

[0091] Specifically, when the packaging box is conveyed along the conveying direction L to the area below the pressing component 30, the driving cylinder 302 can drive the base plate 303 to move downward along the height direction, thereby pressing the items inside the packaging box with a pair of pressing plates 305 and a pair of limiting members 4. Since the contact area between the pair of pressing plates 305 and the items inside the packaging box is large, items that are a certain distance beyond the opening of the packaging box can be reliably pressed into the packaging box. Then, the pair of pressing plates 305 are driven upward along the height direction by a pair of telescopic cylinders 304, thereby avoiding the risk of pressing the pressing plates 305 into the packaging box during the process of flipping the pair of first box lids to the first closed state by the pair of first push-cover components 31. After the pair of first box lids are flipped to the first closed state, the driving cylinder 302 drives the base plate 303 to move the pair of limiting members 4 upward along the height direction away from the packaging box. At this time, the items inside the packaging box have been confined inside the packaging box by the pair of first box lids. This makes it easier for the pair of second push-cover components 32 to push the corresponding pair of second box lids to flip to the second closed state.

[0092] Optionally, in another embodiment, the first driving member 300 can be configured as an electric telescopic push rod with one end fixedly connected to the frame 1 and the other end movable in the height direction. The pressing member 301 is provided with a pressure roller arranged in the width direction and fixedly connected to the driving end of the electric telescopic push rod. When the packaging box is conveyed to the lower part of the pressing member 30 along the conveying direction L, the pressure roller can be driven to move downward in the height direction by the electric telescopic push rod, so that the pressure roller presses the item into the packaging box.

[0093] Furthermore, the structure and arrangement of the limiting component 4 are not limited.

[0094] In one feasible implementation, such as Figure 6As shown, to further ensure that the limiting member 4 will not lift the first box cover again during the upward movement, each limiting member 4 is configured to include a connecting rod 40, one end of which is rotatably connected to the base plate 303 about the conveying direction L and the other end extending downward along the height direction; a connecting seat 41 rotatably connected to the other end of the connecting rod 40 about the conveying direction L; a pair of pressure rods 42 correspondingly disposed on both sides of the connecting seat 41 in the conveying direction L and extending away from each other in the conveying direction L; and a pair of elastic members 43 correspondingly disposed on both sides of the connecting rod 40. Furthermore, one end of each pressure rod 42 is rotatably connected to a corresponding side of the corresponding connecting seat 41 about the width direction W, and one end of each elastic member 43 is fixedly connected to a corresponding side of the corresponding connecting rod 40, and the other end extends to a position near the connecting rod 40 where it is fixedly connected to the corresponding pressure rod 42. It should be understood that one end of each pressure rod 42 is rotatably connected to the connecting seat 41.

[0095] Specifically, when the first box lids are flipped to the first closed state, the drive cylinder 302 drives the base plate 303 to move the pair of limiting members 4 upwards along the height direction away from the packaging box. If the pressure rod 42 collides with the first box lid, pressure can be applied to the pressure rod 42 through the first box lid. After the elastic member 43 is stretched and deformed, the end of the pressure rod 42 away from the connecting seat 41 in the conveying direction L swings downwards. At the same time, the connecting seat 41 is pushed by the pressure rod 42 and will swing the connecting rod 40 around the conveying direction L, thereby causing the connecting rod 40 to move in the width direction W. At this time, the connecting rod 40 and the pressure rod 42 move in the width direction W, thus separating from the first box lid and realizing the retraction of the pressure rod 42. During this process, when the pressure rod 42 collides with the first box lid, the pressure rod 42 will avoid each other when under force, thus avoiding the problem of the pressure rod 42 lifting the first box lid again during the upward movement. The elastic element 43 that needs to be understood can be set as a telescopic spring, an elastic rubber column, etc., but this embodiment does not limit it.

[0096] It should be understood that when the first box lid is flipped to the first closed state, the first push-lid component 31 still limits the first box lid in the height direction. Only after the limiting component 4 leaves the packaging box will the first push-lid component 31 release the limitation on the first box lid.

[0097] Furthermore, in one implementation, such as Figure 6As shown, to limit the swing amplitude of the connecting rod 40 in the width direction W when under force, this folding and sealing machine also includes a limiting member 5 fixedly installed in the middle of the base plate 303 and extending toward the conveying assembly 2 in the height direction; and the limiting member 5 includes a mounting base 50 protruding from the middle of the base plate 303 toward the conveying assembly 2, and a pair of connecting rods 51 corresponding to a pair of limiting members 4 respectively. One end of each connecting rod 51 is rotatably connected to the side of the mounting base 50 near the corresponding limiting member 4 about the conveying direction L, and the other end extends toward the connecting seat 41 of the corresponding limiting member 4 and is rotatably connected to the corresponding connecting seat 41 about the conveying direction L.

[0098] Specifically, when the connecting seat 41 is subjected to the pushing force of one end of the pressure rod 42, the connecting rod 40 swings around the conveying direction L, causing the connecting rod 40 to move in the width direction W in conjunction with the pressure rod 42. The displacement distance of the corresponding connecting rod 40 can be limited by the connecting rod 51, thereby limiting the displacement of the pressure rod 42 in the width direction W. This reduces the risk of the pressure rod 42 moving too far in the width direction W, which could squeeze the inner wall of the box and cause damage to the packaging box.

[0099] Furthermore, in one implementation, such as Figure 4 and Figure 5 As shown, to improve the stability of the substrate 303 and the lower pressure plate 305 during the movement along the height direction, a first guide mechanism is also provided between the substrate 303 and the frame 1. The first guide mechanism includes a pair of first guide rods 306 spaced apart on both sides of the drive cylinder 302 in the width direction W. The pair of first guide rods 306 extend from the substrate 303 toward the frame 1 in the height direction, and one end of each first guide rod 306 is slidably connected to the substrate 303, while the other end is fixedly connected to the frame 1. Thus, during the movement of the drive cylinder 302 in the height direction, the first guide rods 306 can guide and limit the substrate 303, making the substrate 303 more stable during movement and preventing positional deviation. Furthermore, the first guide rods 306 can also improve the synchronization of the two sides of the substrate 303 in the width direction W during movement.

[0100] In addition, a second guide mechanism is provided between each lower pressure plate 305 and the base plate 303. The second guide mechanism includes a pair of second guide rods 307 spaced apart on both sides of the telescopic cylinder 304 in the width direction W. The pair of second guide rods 307 extend from the base plate 303 toward the lower pressure plate 305 in the height direction, and one end of each second guide rod 307 is fixedly connected to the base plate 303, and the other end is slidably connected to the corresponding lower pressure plate 305. Thus, when the telescopic cylinder 304 drives the pressure plate 305 to move in the height direction, the second guide rods 307 can guide and limit the lower pressure plate 305, making the lower pressure plate 305 more stable when moving and preventing positional deviation. Furthermore, the second guide rods 307 can also make the synchronization of the lower pressure plate 305 on both sides in the width direction W higher during the movement.

[0101] The structure and arrangement of the pair of first push-cover components 31 will be further explained below.

[0102] Specifically, such as Figure 4 As shown, each first push cover component 31 includes a lifting component 310 mounted on the frame 1, a connecting base 311 mounted on the driving end of the lifting component 310, a second driving component 312 fixedly mounted on the connecting base 311, and a first push plate 313 transmissionally connected to the driving end of the second driving component 312; and the driving end of the lifting component 310 can move along the height direction, and the driving end of the second driving component 312 can move along the conveying direction L.

[0103] Specifically, when the packaging box is conveyed along the conveying direction L to the area below the pressing component 30, and the contents of the packaging box are pressed down by the pressing component 30, the connecting base 311 can be driven to move downward along the height direction by the lifting component 310 of each first push cover component 31, so that the first push plate 313 is directly opposite the first cover of the packaging box in the conveying direction L. Then, the second driving component 312 drives the first push plate 313 to move toward the corresponding first cover and pushes the first cover to flip to the first closed state. During this process, since the lifting component 310 can drive the connecting base 311 to move along the height direction, the first push plate 313 will not interfere with the conveying of the packaging box when the packaging box is conveyed along the conveying direction L to the area below the pressing component 30.

[0104] More specifically, since the lifting component 310 can drive the connecting base 311 to move along the height direction, and the second driving component 312 can drive the first push plate 313 to move, by changing the displacement distance of the base in the height direction and the displacement distance of the first push plate 313, this folding and sealing machine can be applied to packaging boxes of different height and length dimensions, and has the advantage of wide applicability.

[0105] Furthermore, a third guide mechanism is provided between the connecting base 311 and the frame 1. The third guide mechanism includes a pair of third guide rods 308 that are spaced apart on the connecting base 311 in the width direction W and located on both sides of the second driving member 312. The pair of third guide rods 308 extend from the connecting base plate 303 toward the frame 1 in the height direction. One end of each third guide rod 308 is fixedly connected to the frame 1, and the other end is slidably connected to the connecting base 311. Thus, when the second driving member 312 drives the base to move in the height direction, the pair of third guide rods 308 can guide and limit the base, making the base more stable during movement and preventing positional deviation. In addition, the third guide rods 308 can also make the synchronicity of the two sides of the base in the width direction W higher during movement.

[0106] It should be understood that the structure and arrangement of the lifting component 310 are not limited, such as being a lifting cylinder, a linear motor, an electric push rod, etc. The structure and arrangement of the second driving component 312 are not limited, such as being a driving cylinder, a telescopic cylinder, a linear motor, etc. This embodiment does not make specific limitations here.

[0107] The structure and arrangement of the second push cover component 32 will be further explained below.

[0108] Specifically, such as Figure 5 As shown, each second push cover component 32 includes a mounting plate 320 mounted on the frame 1, a third drive component 323 fixedly mounted on the mounting plate 320, a second push plate 321 driven by the third drive component 323, and a pair of slide rails 322 symmetrically arranged on the mounting plate 320 and located on both sides of the third drive component 323 in the conveying direction L. The pair of slide rails 322 are slidably connected to the mounting plate 320, and one end of the slide rails 322 near the second push plate 321 in the width direction W is fixedly connected to the second push plate 321.

[0109] Specifically, when it is necessary to flip the pair of second lids of the packaging box to the second closed state, the third driving component 323 drives the second push plate 321 to move along the width direction W toward the corresponding second lid, and the second push plate 321 pushes the second lid to flip to the second closed state. Therefore, when the size of the packaging box changes in the width direction W, the purpose of pushing the second lid can be achieved by changing the moving distance of the second push plate 321 along the width direction W driven by the third driving component 323. Therefore, this lid-folding and sealing machine also has the advantage of adapting to packaging boxes of different width sizes in the width direction W when folding lids.

[0110] It should be understood that the structure and arrangement of the third drive component 323 are not limited, and can be a telescopic cylinder, an electric push rod, etc. This embodiment does not limit it to a single one.

[0111] The structure and configuration of the conveying component 2 will be further explained below.

[0112] like Figure 1 and Figure 2 As shown, the conveying assembly 2 includes a support platform 20 extending along the conveying direction L and disposed on the frame 1, and a pair of clamping members 21 extending along the conveying direction L and located on both sides of the support platform 20 in the width direction W.

[0113] Specifically, during the transport of the packaging boxes, the boxes are placed on the support platform 20. The support platform 20 provides height support for the boxes, ensuring stable transport. Furthermore, a pair of clamping components 21 are respectively attached to the corresponding side of the packaging box body, thereby limiting the width W of the box and preventing positional shifts during transport. This allows both the first and second lids of the packaging box to be accurately flipped using the folding assembly 3.

[0114] More specifically, the structure and arrangement of the clamping component 21 are not limited. For example, it can be a limiting plate or a limiting seat that extends along the conveying direction L and is arranged on the frame 1. This embodiment does not make specific limitations here.

[0115] In addition, there are various ways to set up the transportation method of the packaging box. This embodiment does not make specific limitations here. The following examples will be used for illustration.

[0116] Optionally, in one embodiment, a conveyor belt that can move along the conveying direction L is provided on the support platform 20, and the packaging box is then conveyed by the conveyor belt.

[0117] Optionally, in another embodiment, each clamping component 21 includes a mounting frame 61 extending along the conveying direction L and mounted on the mounting frame 61 along the conveying direction L. The conveying surfaces of the conveyor belts of the pair of clamping components 21 are opposite to each other in the width direction W. When conveying the packaging box, the packaging box is clamped by the pair of clamping components 21 and then moved along the conveying direction L by the conveyor belt to realize the conveying of the packaging box.

[0118] Furthermore, when the clamping component 21 is configured to include a conveyor belt, the support platform 20 is configured to include a plurality of rotating rollers spaced apart on the frame 1 along the conveying direction L. Each rotating roller is arranged along the width direction W and its two ends are rotatably connected to the frame 1. When the conveying assembly 2 conveys the carton, the carton is placed on the support platform 20, and a pair of clamping components 21 clamp the carton body and drive the carton to move on the support platform 20 along the conveying direction L. Since the two ends of each rotating roller are rotatably connected to the frame 1, the friction between the support platform 20 and the carton can be reduced.

[0119] Furthermore, in order to enable the pair of clamping components 21 to adapt to packaging boxes of different widths, in one embodiment, the pair of clamping components 21 are mounted on the frame 1 and can move along the width direction W. The conveying assembly 2 also includes an adjustment component 22 mounted on the frame 1. The adjustment component 22 is connected to the pair of clamping components 21 in a transmission manner, so that the spacing between the pair of clamping components 21 in the width direction W can be adjusted by the adjustment component 22, thereby enabling the pair of clamping components 21 to adapt to packaging boxes of different sizes. For example, when the size of the packaging box in the width direction W decreases, the pair of clamping components 21 can be driven to move towards each other in the width direction W by the adjustment component 22 to limit the packaging box.

[0120] In addition, the frame 1 is also provided with a limiting part 10 located below the folding assembly 3 in the height direction; wherein, when the packaging box is conveyed to the lower part of the folding assembly 3 along the conveying direction L, the limiting part 10 limits the two sides of the packaging box in the width direction W and the front side in the conveying direction L, so that the position of the packaging box will not be shifted when the folding assembly 3 folds the packaging box, so that the folding assembly 3 can accurately fold the packaging box.

[0121] Specifically, the structure and setting of the adjustment component 22 are not limited.

[0122] Optionally, in one embodiment, the adjusting component 22 includes a screw arranged along the width direction W and rotatably connected to the frame 1 at both ends, a drive handwheel fixedly installed at one end of the screw, and a first transmission rod and a second transmission rod spaced apart along the width direction W on the screw; and the screw has a positive thread section and a negative thread section formed thereon. In the height direction, one end of the first transmission rod is threaded to the positive thread section, and the other end is fixedly connected to one of the corresponding pair of clamping components 21; one end of the second transmission rod is threaded to the negative thread section, and the other end is fixedly connected to the other clamping component 21 in the corresponding pair of clamping components 21.

[0123] Specifically, when it is necessary to change the distance between a pair of clamping components 21, the drive handwheel can be rotated in the forward or reverse direction to rotate the screw, thereby adjusting the spacing between the pair of clamping components 21 in the width direction W.

[0124] Optionally, in another embodiment, the adjustment component 22 includes a pair of linear motors mounted on the frame 1 and corresponding one-to-one with and connected to a pair of clamping components 21. The drive end of each linear motor can move along the width direction W. Each linear motor is used to drive the corresponding clamping component 21 to move along the width direction W, thereby changing the spacing between the pair of clamping components 21 in the width direction W.

[0125] The structure and arrangement of the limiting part 10 will be further explained below.

[0126] Specifically, such as Figure 1 and Figure 2 As shown, the limiting part 10 includes a side limiting component 11 and a front limiting component 12 disposed on the frame 1; wherein, when the packaging box is conveyed along the conveying direction L to the bottom of the folding assembly 3, the side limiting component 11 limits the two sides of the packaging box body in the width direction W, and the front limiting component 12 limits the front side of the packaging box body in the conveying direction L.

[0127] Therefore, by setting the front limiting component 12, when the packaging box is conveyed along the conveying direction L to the bottom of the folding assembly 3, the packaging box can be limited in the conveying direction L, avoiding the risk of the packaging box shifting in the conveying direction L during the folding process. This allows the pair of first push-lid components 31 to accurately push the first lid of their respective packaging boxes, and the first lids on both sides of the packaging box in the conveying direction L can accurately flip to the first closed state. By setting the side limiting component 11, when the packaging box is conveyed along the conveying direction L to the bottom of the folding assembly 3, the packaging box can be limited in the width direction W, avoiding the risk of the packaging box shifting in the width direction W during the folding process. This allows the pair of second push-lid components 32 to accurately push the second lid of their respective packaging boxes, and the second lids on both sides of the packaging box in the width direction W can accurately flip to the second closed state.

[0128] Specifically, the structure and arrangement of the side limiting component 11 and the front limiting component 12 are not limited, and the following is an example.

[0129] Optionally, in one embodiment, the side-end limiting member 11 includes a pair of side-end limiting brackets located on both sides of the support platform 20 in the width direction W, and the pair of side-end limiting brackets corresponds one-to-one with a pair of clamping members 21. In the height direction, each side-end limiting bracket is located above the corresponding clamping member 21.

[0130] Specifically, each side-end limiting bracket includes a base plate 303 fixedly mounted on the frame 1, multiple fixing rods spaced apart along the conveying direction L, and a limiting seat located directly above the corresponding clamping component 21. One end of each fixing rod is fixedly connected to the base plate 303, and the other end extends along the width direction W and is fixedly connected to the limiting seat. When the packaging box is conveyed to the area directly below the folding assembly 3, the box body fits against the outer wall surface of the limiting seat of the pair of side-end limiting brackets, thereby limiting the upper end of the box body in the height direction and further ensuring that the position of the packaging box will not shift when the folding assembly 3 folds the box.

[0131] More specifically, the front limiting component 12 includes a fixed plate fixedly installed on the frame 1, a telescopic component installed on the fixed plate, and a limiting plate fixedly installed on the drive end of the telescopic component; wherein, when the packaging box is conveyed to the underside of the folding assembly 3, the telescopic component of the front limiting component 12 moves along the width direction W, and the box body fits against the limiting plate of the front limiting component 12, thereby limiting the packaging box in the conveying direction L and avoiding the risk of the packaging box shifting in the conveying direction L during the folding process.

[0132] It should be understood that the telescopic component can be set as an electric telescopic push rod, a telescopic cylinder 304, etc., and this embodiment does not limit it.

[0133] Furthermore, in one embodiment, to prevent the items inside the packaging box from opening the first and second lids again after the box is closed by the folding assembly 3, the folding and sealing machine also includes a sealing assembly 6 mounted on the frame 1 and located downstream of the folding assembly 3, and the sealing assembly 6 is located above the conveying assembly 2 in the height direction; wherein the sealing assembly 6 includes a mounting frame 61 mounted on the frame 1 that is movable in the height direction, and a sealing component 60 mounted on the mounting frame 61, and the support platform 20 is located below the sealing component 60 in the height direction.

[0134] Specifically, when the packaging box is conveyed along the conveying direction L to the bottom of the flap assembly 3, the pair of second box flaps can be sealed by adhesive tape through the sealing component 60, which reduces the risk that the pair of first box flaps and the pair of second box flaps of the packaging box will be opened again due to the rebound of the items inside the packaging box, making the subsequent transportation of the packaging box containing the items safer and more reliable.

[0135] Furthermore, by providing a mounting bracket 61 that can move along the height direction, the distance between the sealing component 60 and a pair of second box lids can be adjusted to accommodate further sealing of boxes of different heights.

[0136] It should be understood that the sealing component 60 is a commonly used sealing mechanism in the field, the purpose of which is to seal the lid of the packaging box with tape. This embodiment does not limit its specific structure.
