Description

Technical Field

[0001] This utility model relates to the technical field of cartoning equipment, and in particular to a sealing device for a cartoning machine. Background Technology

[0002] In the field of automated packaging equipment, the sealing device of a cartoning machine is a key functional unit for achieving the closure of the packaging box.

[0003] In some product packaging, horizontal cartoning machines are used. Existing technology discloses a folding and labeling device and method for automatic packaging of electronic products, patent number CN111661435A. This device can be classified as a horizontal cartoning machine. Structurally, the surface of the turntable has multiple clamping structures arranged along the circumference. The filling component and sealing component are distributed around the turntable. When this device is used for cartoning, the opening on one side of the cardboard box needs to be manually sealed beforehand. The opening on the other side of the cardboard box is used to allow the product to enter the box. Then, the cardboard box is laid flat in the clamping structure. At this time, the opening of the cardboard box is close to the outer circumference of the turntable. The filling component pushes the opening of the cardboard box into the product, and then the sealing component seals the opening of the cardboard box.

[0004] However, existing sealing components can only seal one opening of the carton on the outer periphery of the turntable. Since the other opening of the carton is close to the rotation axis of the turntable, this opening can only be sealed manually in advance, which requires more sealing personnel. Furthermore, the low level of automation of the cartoning equipment reduces the efficiency of the cartoning operation. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a sealing device for a cartoning machine that eliminates the need for manual sealing operations, thereby improving the automation level of the cartoning equipment and increasing cartoning efficiency.

[0006] A sealing device for a cartoning machine according to an embodiment of the present invention, the cartoning machine including a turntable, the turntable having a support surface and a positioning component disposed on the support surface, the positioning component being used to limit the position of the carton, characterized in that the sealing device includes an ear-folding mechanism, a cover-folding mechanism, a tongue-folding mechanism and a closing mechanism located on the side of the positioning component near the rotation axis of the turntable, the ear-folding mechanism being used to fold two ears of the carton toward the opening of the carton, the cover-folding mechanism being used to fold the cover plate of the carton toward the opening of the carton, the tongue-folding mechanism being used to fold the tongue of the cover plate toward the opening of the carton, and the closing mechanism being used to insert the tongue of the cover plate into the opening of the carton.

[0007] A sealing device for a cartoning machine according to an embodiment of the present invention has at least the following beneficial effects:

[0008] This invention employs a folding ear mechanism, a folding lid mechanism, a folding tongue mechanism, and a closing mechanism. These mechanisms are positioned between the positioning component and the rotating shaft of the turntable. This arrangement positions the sealing device close to the opening of the cardboard box facing the rotating shaft of the turntable. During the box sealing process, the folding ear mechanism folds the two ears of the cardboard box towards the opening. Next, the folding lid mechanism folds the lid towards the opening. Then, the folding tongue mechanism folds the tongue of the lid towards the opening. Finally, the closing mechanism inserts the tongue of the lid into the opening of the cardboard box, thus sealing the opening facing the rotating shaft of the turntable. This eliminates the need for manual sealing, increasing the automation level of the cartoning equipment, improving cartoning efficiency, and reducing labor costs. Furthermore, the folding ear mechanism, folding lid mechanism, folding tongue mechanism, and closing mechanism fully utilize the space between the positioning component and the rotating shaft of the turntable, reducing the footprint of the sealing device.

[0009] According to an embodiment of the present invention, a sealing device for a cartoning machine includes a folding lug mechanism comprising two folding lug components, with the rotating shaft of the turntable housed between the two folding lug components. The two folding lug components can move relative to each other and approach each other so that the two lugs fold toward the opening of the carton.

[0010] The advantage is that, due to the narrow space between the positioning component and the rotation axis of the turntable, this utility model solves the problem of the narrow space between the positioning component and the rotation axis of the turntable, which makes it difficult to arrange the folding mechanism structure. Thus, the space on the turntable can be fully utilized.

[0011] In addition, the two folding lugs fold the two lugs of the cardboard box toward the opening of the cardboard box, and the two folding lugs fold at the same time, which can improve the folding efficiency of the cardboard box.

[0012] According to an embodiment of the present invention, a sealing device for a cartoning machine includes a folding ear mechanism that further includes a first moving component. The first moving component includes a moving frame and a first power component that drives the moving frame to move. The moving frame is located on the side of the positioning component away from the sealing station on the rotation axis of the turntable. Two folding ear components are connected to the moving frame to move closer to the opening of the carton.

[0013] The advantages of this invention are: by setting up a movable frame and a first power component, the first power component drives the movable frame to approach the opening of the cardboard box, and the movable frame moves the folding ear assembly to the folding ear position, which facilitates the precise folding of the folding ear assembly. Furthermore, by using the first power component to drive the movable frame away from the opening of the cardboard box, the folding ear assembly is moved away from the positioning component, thus avoiding interference between the positioning component and the folding ear assembly during the rotation of the turntable.

[0014] In addition, the movable frame is located on the side of the turntable's rotation axis away from the positioning component. The space on the side of the turntable's rotation axis away from the positioning component is larger, which makes it easier to arrange the movable frame and allows for the design of a larger movable frame, which is beneficial to improving the stability of the movable frame.

[0015] According to an embodiment of the present invention, a sealing device for a cartoning machine includes a cantilever, a first push block connected to the end of the cantilever, and a second power component that drives the cantilever to move. The cantilever extends along the radial direction of the turntable and toward the positioning component near the sealing station. The first push block is used to push one ear of the carton.

[0016] The advantages of this invention are: by setting up a cantilever, a first push block and a second power component, the second power component drives the cantilever to move, so that the first push block moves with the cantilever and folds the ear of the cardboard box toward the opening of the cardboard box. Furthermore, the second power component does not need to be directly connected to the first push block, so that the second power component can be kept away from the positioning component, reducing the space occupied around the positioning component and facilitating the arrangement of the folding cover mechanism, the folding tongue mechanism and the closing mechanism around the positioning component.

[0017] A sealing device for a cartoning machine according to an embodiment of the present invention further includes a bracket, the bracket being located between the two folding lug assemblies, and the flap folding mechanism, the tongue folding mechanism, and the closing mechanism being mounted on the bracket.

[0018] The advantages of this invention are: by setting up a bracket and arranging the bracket in the space between the two folding lug components, and by installing the folding cover mechanism, the folding tongue mechanism and the closing mechanism on the bracket, the folding cover mechanism, the folding tongue mechanism and the closing mechanism can make full use of the space between the two folding lug components, making the sealing device structure more compact.

[0019] According to an embodiment of the present invention, a sealing device for a cartoning machine includes a folding mechanism comprising a folding block and a third power component for moving the folding block, wherein the folding block is used to push the cover plate.

[0020] The advantages of this invention are: by setting a folding block and a third power component, the third power component drives the folding block to move, and the folding block can push the cover plate so that the cover plate folds towards the opening of the cardboard box, which makes it easier for the folding tongue mechanism to accurately fold the tongue towards the opening of the cardboard box.

[0021] According to an embodiment of the present utility model, a sealing device for a cartoning machine further includes a suction mechanism. The suction mechanism is located on the side of the positioning component away from the support surface at the sealing station. The suction mechanism includes a suction component and a fourth power component that drives the suction component to move. The suction component is used to suction the side wall of the carton connected to the cover plate.

[0022] The advantage of this invention is that by setting up a suction box mechanism, the positioning component of the suction box mechanism at the sealing station is located on the side away from the support surface, which allows for a larger arrangement space for the suction box mechanism and facilitates its installation and fixation.

[0023] Furthermore, by setting up a suction component and a fourth power component, the present invention uses the fourth power component to drive the suction component to move, and the suction component sucks up the opposite side wall of the paper box side wall connected to the cover plate to prevent the paper box side wall from sinking inward, so as to facilitate the subsequent accurate insertion of the tongue into the opening of the paper box.

[0024] According to an embodiment of the present utility model, a sealing device for a cartoning machine includes a flap mechanism comprising a flap component and a fifth power component for moving the flap component. The flap component includes a first abutting plate and a second abutting plate connected to each other. The first abutting plate is used to abut against the tongue piece, and the second abutting plate is used to abut against the cover plate.

[0025] The advantages of this invention are: by setting up a folding tongue and a fifth power component, the fifth power component drives the folding tongue to move. The folding tongue abuts against the tongue piece with the first abutting plate, so that the tongue piece folds towards the opening of the cardboard box. The second abutting plate abuts against the cover plate, so as to push the cover plate to a vertical state, which makes it easier for the closing mechanism to push the cover plate, so that the tongue piece can be accurately inserted into the opening of the cardboard box.

[0026] According to an embodiment of the present invention, a sealing device for a cartoning machine includes a lid-closing mechanism comprising two lid-closing components. The two lid-closing components are distributed along the support surface on opposite sides of the flap mechanism. Each lid-closing component includes a second push block and a sixth power component that drives the second push block to move. The second push block is used to push the lid.

[0027] The advantages are: by setting two cover-closing components, which are distributed on opposite sides of the flap mechanism along the support surface, the cover-closing components are positioned close to the middle of the carton thickness direction. Furthermore, by setting a second push block and a sixth power component, the sixth power component drives the second push block, and the second push blocks of the two cover-closing components simultaneously push the cover plate, allowing the flap to be smoothly inserted into the carton.

[0028] According to an embodiment of the present invention, a sealing device for a cartoning machine further includes a guide, the guide having a first guide plate and a second guide plate disposed opposite to each other, and the cover plate passing between the first guide plate and the second guide plate before the positioning component moves to the sealing station.

[0029] The advantages are: by setting a guide, the positioning component follows the turntable to rotate. Before the box is sealed, the positioning component passes through the guide. The guide uses the first guide plate and the second guide plate to limit the position of the box cover, so as to prevent the box cover from tilting up higher than the standard working position, which would prevent the folding mechanism from being unable to perform the folding operation. It also prevents the box cover from drooping down lower than the standard working position, which would cause the ear of the box and the cover to interfere with each other when the ear folding mechanism is folding.

[0030] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0043] The sealing device of a cartoning machine according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0044] Reference Figure 1 The present invention aims to provide an embodiment of a sealing device for a cartoning machine.

[0045] In the construction of the cardboard box, refer to Figure 6 The cardboard box includes a box body 370, ears 380 and a cover 390. The box body 370 has openings at both ends. Each opening is provided with a cover 390 and two ears 380. The two ears 380 are respectively connected to the opposite side walls of the opening of the box body 370. The cover 390 is connected to one side wall of the box body 370 and is located between the two ears 380. The edge of the cover 390 away from the box body 370 has a tongue 400.

[0046] It should be noted that the openings at both ends of the box body 370 are arranged along the length of the box body 370. On the plane where the openings are located, the two ears 380 are arranged along the width of the box body 370, and the cover plate 390 is arranged along the thickness of the box body 370.

[0047] Typically, cartoning machines include horizontal disc cartoning machines and vertical disc cartoning machines. Horizontal disc cartoning machines can operate on horizontally placed cartons with the length of the cartons in the horizontal direction, while vertical disc cartoning machines can operate on vertically placed cartons with the length of the cartons in the vertical direction. In this embodiment, a horizontal disc cartoning machine is used as an example.

[0048] A sealing device for a cartoning machine according to an embodiment of this utility model, referring to... Figure 5 The cartoning machine includes a turntable 100, which has a support surface and a positioning component 110 disposed on the support surface. The positioning component 110 is used to limit the position of the carton.

[0049] Furthermore, referring to Figure 1 and Figure 5 The sealing device includes an ear folding mechanism 120, a cover folding mechanism 130, a tongue folding mechanism 140, and a closing mechanism 150 located on the side of the positioning assembly 110 near the rotation axis of the turntable 100. The ear folding mechanism 120 is used to fold the two ears 380 of the paper box toward the opening of the paper box. The cover folding mechanism 130 is used to fold the cover plate 390 of the paper box toward the opening of the paper box. The tongue folding mechanism 140 is used to fold the tongue 400 of the cover plate 390 toward the opening of the paper box. The closing mechanism 150 is used to insert the tongue 400 of the cover plate 390 into the opening of the paper box.

[0050] It is understood that in this embodiment, by setting up an ear-folding mechanism 120, a cover-folding mechanism 130, a tongue-folding mechanism 140, and a closing mechanism 150, and arranging these mechanisms between the positioning assembly 110 and the rotation axis of the turntable 100, the sealing device is positioned close to the opening of the cardboard box facing the rotation axis of the turntable 100. Therefore, during the cardboard box sealing process, the ear-folding mechanism 120 folds the two ears 380 of the cardboard box towards the opening of the cardboard box, and then the cover-folding mechanism 130 folds the cover plate 390 of the cardboard box towards the opening of the cardboard box. Next, the folding tongue mechanism 140 folds the tongue 400 of the cover plate 390 toward the opening of the carton. Finally, the closing mechanism 150 inserts the tongue 400 of the cover plate 390 into the opening of the carton, thus sealing the opening of the carton facing the rotation axis of the turntable 100. This eliminates the need for manual sealing operations, improves the automation level of the cartoning equipment, increases cartoning efficiency, and reduces labor costs. Furthermore, the folding ear mechanism 120, the folding lid mechanism 130, the folding tongue mechanism 140, and the closing mechanism 150 make full use of the space between the positioning component 110 and the rotation axis of the turntable 100, reducing the footprint of the sealing device.

[0051] In some embodiments of this utility model, reference is made to Figure 3 It also includes a guide 340, which has a first guide plate 350 and a second guide plate 360 ​​arranged opposite to each other. Before the positioning assembly 110 moves to the sealing station, a cover plate 390 is accommodated between the first guide plate 350 and the second guide plate 360.

[0052] It is understood that in this embodiment, by setting the guide 340, the positioning component 110 rotates with the turntable 100. Before the box sealing operation of the positioning component 110, it will pass through the guide 340. The guide 340 uses the first guide plate 350 and the second guide plate 360 ​​to restrict the position of the box cover 390, so as to prevent the box cover 390 from tilting up higher than the standard working position, which would prevent the folding mechanism 130 from performing the folding operation. It also prevents the box cover 390 from drooping down lower than the standard working position, which would cause the ear 380 of the box and the cover 390 to interfere with each other when the ear folding mechanism 120 folds the ear.

[0053] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 The folding mechanism 120 includes two folding assemblies 160, with the rotation axis of the turntable 100 housed between the two folding assemblies 160. The two folding assemblies 160 can move relative to each other and approach each other so that the two ears 380 fold toward the opening of the cardboard box.

[0054] Understandably, due to the narrow space between the positioning component 110 and the rotation axis of the turntable 100, this utility model solves the problem of the narrow space between the positioning component 110 and the rotation axis of the turntable 100, which makes it difficult to arrange the folding mechanism 120 structure. This is achieved by setting two folding lug components 160 with a clearance space between them, which can avoid the rotation axis of the turntable 100.

[0055] In addition, the two folding lug assemblies 160 fold the two lugs 380 of the cardboard box toward the opening of the cardboard box respectively. The two folding lug assemblies 160 perform the folding work at the same time, which can improve the folding efficiency of the cardboard box.

[0056] In some embodiments of this utility model, reference is made to Figure 2 The folding mechanism 120 also includes a first moving component, which includes a moving frame 170 and a first power component 180 that drives the moving frame 170 to move. The moving frame 170 is located on the side of the rotating axis of the turntable 100 away from the positioning component 110 at the sealing station. Two folding components 160 are connected to the moving frame 170 to move closer to the opening of the carton. It should be noted that the first power component 180 can be powered by a cylinder, which is not specifically limited here.

[0057] It is understood that in this embodiment, by setting a movable frame 170 and a first power member 180, the first power member 180 drives the movable frame 170 to approach the opening of the cardboard box. The movable frame 170 can move along the length direction of the cardboard box, which can be consistent with the Y-axis of the horizontal direction. The movable frame 170 moves the folding ear assembly 160 to the folding ear position, so that the folding ear assembly 160 can fold the ear accurately. Furthermore, the first power member 180 drives the movable frame 170 away from the opening of the cardboard box, so that the folding ear assembly 160 is away from the positioning component 110, thus avoiding interference between the positioning component 110 and the folding ear assembly 160 during the rotation of the turntable 100.

[0058] In addition, the movable frame 170 is located on the side of the rotating axis of the turntable 100 away from the positioning component 110 at the sealing station. The space on the side of the rotating axis of the turntable 100 away from the positioning component 110 is larger, which makes it easier to arrange the movable frame 170 and allows for the design of a larger movable frame 170, which is beneficial to improving the stability of the movable frame 170.

[0059] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4The folding ear assembly 160 includes a cantilever 210, a first push block 220 connected to the end of the cantilever 210, and a second power component 200 that drives the cantilever 210 to move. The cantilever 210 extends along the radial direction of the turntable 100 and toward the positioning assembly 110 near the sealing station. The first push block 220 is used to push one ear 380 of the carton. It should be noted that the second power component 200 can use a cylinder as a power source, which is not specifically limited here.

[0060] It is understood that in this embodiment, by setting up a cantilever 210, a first push block 220 and a second power member 200, the second power member 200 drives the cantilever 210 to move, so that the first push block 220 moves with the cantilever 210. The first push block 220 can move along the width direction of the cardboard box, and the width direction of the cardboard box can be consistent with the horizontal X-axis, so that the first push block 220 folds the ear 380 of the cardboard box toward the opening of the cardboard box. Furthermore, the second power member 200 does not need to be directly connected to the first push block 220, so that the second power member 200 can be away from the positioning component 110, reducing the space occupied around the positioning component 110, and facilitating the arrangement of the folding cover mechanism 130, the folding tongue mechanism 140 and the closing mechanism 150 around the positioning component 110.

[0061] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 It also includes a bracket 230, which is located between two folding lug assemblies 160. The folding cover mechanism 130, the folding tongue mechanism 140, and the closing mechanism 150 are mounted on the bracket 230.

[0062] It is understood that in this embodiment, by setting up a bracket 230, the bracket 230 is arranged in the space between the two folding lug assemblies 160, and the folding cover mechanism 130, the folding tongue mechanism 140 and the closing mechanism 150 are installed on the bracket 230, so that the folding cover mechanism 130, the folding tongue mechanism 140 and the closing mechanism 150 make full use of the space between the two folding lug assemblies 160, making the sealing device structure more compact.

[0063] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 The cover-folding mechanism 130 includes a cover-folding block 240 and a third power component 250 that drives the cover-folding block 240 to move. The cover-folding block 240 is used to push the cover plate 390. It should be noted that the third power component 250 can be powered by a cylinder, and no specific limitation is made here.

[0064] It is understood that in this embodiment, by setting a folding block 240 and a third power component 250, the third power component 250 drives the folding block 240 to move. The folding block 240 can move along the thickness direction of the cardboard box, and the thickness direction of the cardboard box can be consistent with the vertical Z-axis. The folding block 240 can push the cover plate 390, so that the cover plate 390 folds towards the opening of the cardboard box, which facilitates the subsequent folding tongue mechanism 140 to accurately fold the tongue 400 towards the opening of the cardboard box.

[0065] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 It also includes a suction box mechanism 260, which is located on the side of the positioning component 110 away from the support surface. The suction box mechanism 260 includes a suction component 270 and a fourth power component 280 that drives the suction component 270 to move. The suction component 270 is used to suction the side wall of the cardboard box connected to the cover plate 390. It should be noted that the fourth power component 280 can be powered by a cylinder, which is not specifically limited here.

[0066] It is understood that in this embodiment, by setting up a suction box mechanism 260, the suction box mechanism 260 is located on the side of the positioning component 110 at the sealing station away from the support surface. This allows for a larger arrangement space for the suction box mechanism 260, making it easier to install and fix the suction box mechanism 260.

[0067] Furthermore, by setting up a suction component 270 and a fourth power component 280, the fourth power component 280 drives the suction component 270 to move. The suction component 270 can move along the thickness direction of the paper box, and the thickness direction of the paper box can be consistent with the vertical Z-axis. The suction component 270 sucks up the side wall of the paper box connected to the cover plate 390 to prevent the side wall of the paper box from sinking inward, so as to facilitate the subsequent precise insertion of the tongue 400 into the opening of the paper box.

[0068] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 The folding tongue mechanism 140 includes a folding tongue piece 290 and a fifth power member 300 that drives the folding tongue piece 290 to move. The folding tongue piece 290 includes a first abutting plate and a second abutting plate that are connected to each other. The first abutting plate is used to abut against the tongue piece 400, and the second abutting plate is used to abut against the cover plate 390. It should be noted that the fifth power member 300 can be powered by a cylinder, and no specific limitation is made here.

[0069] It is understood that in this embodiment, by setting a folding tongue 290 and a fifth power component 300, the fifth power component 300 drives the folding tongue 290 to move. The folding tongue 290 can move along the length direction of the cardboard box, and the length direction of the cardboard box can be consistent with the horizontal Y-axis. The folding tongue 290 abuts against the tongue 400 using the first abutting plate, so that the tongue 400 folds towards the opening of the cardboard box. The second abutting plate abuts against the cover plate 390 to push the cover plate 390 to tend to a vertical state, so that the subsequent closing mechanism 150 can push the cover plate 390, so that the tongue 400 can be accurately inserted into the opening of the cardboard box.

[0070] In some embodiments of this utility model, reference is made to Figure 3 The cover closing mechanism 150 includes two cover closing components 310, which are distributed along the support surface on opposite sides of the flap mechanism 140. Each cover closing component 310 includes a second push block 320 and a sixth power member 330 that drives the second push block 320 to move. The second push block 320 is used to push the cover plate 390. It should be noted that the sixth power member 330 can be powered by a cylinder, which is not specifically limited here.

[0071] It is understood that in this embodiment, two cover-closing components 310 are provided, which are distributed on opposite sides of the flap mechanism 140 along the support surface. This arrangement makes the cover-closing components 310 close to the middle position in the thickness direction of the paper box.

The second push blocks 320 of the two cover-closing components 310 simultaneously push the cover plate 390, so that the tongue 400 can be smoothly inserted into the inside of the paper box.

[0072] In summary, the working principle of the sealing device of the cartoning machine in this embodiment is as follows:

[0073] First, before the carton sealing operation of the positioning component 110, it passes through the guide 340. The guide 340 uses the first guide plate 350 and the second guide plate 360 ​​to restrict the position of the carton cover 390. Then, the first power component 180 drives the moving frame 170 to approach the opening of the carton. The moving frame 170 can move along the length direction of the carton. The length direction of the carton can be consistent with the horizontal Y-axis. The moving frame 170 moves the folding ear component 160 to the folding ear position, so that the folding ear component 160 can fold the ear accurately.

[0074] Then, the second power component 200 drives the cantilever 210 to move, so that the first push block 220 moves with the cantilever 210. The first push block 220 can move along the width direction of the cardboard box, and the width direction of the cardboard box can be consistent with the horizontal X-axis, so that the first push block 220 folds the ear 380 of the cardboard box toward the opening of the cardboard box.

[0075] Next, the third power component 250 drives the folding block 240 to move. The folding block 240 can move along the thickness direction of the cardboard box. The thickness direction of the cardboard box can be consistent with the vertical Z-axis. The folding block 240 can push the cover plate 390, so that the cover plate 390 folds towards the opening of the cardboard box.

[0076] In addition, the fourth power component 280 drives the suction assembly 270 to move. The suction assembly 270 can move along the thickness direction of the paper box. The thickness direction of the paper box can be consistent with the vertical Z-axis. The suction assembly 270 sucks up the opposite side wall of the paper box side wall connected to the cover plate 390 to prevent the paper box side wall from sinking inward.

[0077] Next, the fifth power component 300 drives the folding tongue component 290 to move. The folding tongue component 290 can move along the length direction of the cardboard box. The length direction of the cardboard box can be consistent with the horizontal Y-axis. The folding tongue component 290 abuts against the tongue piece 400 using the first abutting plate, so that the tongue piece 400 folds towards the opening of the cardboard box.

[0078] Finally, the sixth power component 330 drives the second pusher 320, which can move along the length of the carton. The length of the carton can be aligned with the horizontal Y-axis. The second pushers 320 of the two closing components 310 simultaneously push the cover plate 390, so that the tongue 400 can be smoothly inserted into the inside of the carton to complete the sealing operation.
