[0074] First embodiment

[0075] Please refer to Figures 1 to 4 In the first aspect, an embodiment of the present invention provides a packaging assembly 100 for packaging a rectangular body 400. The packaging assembly 100 can reduce packaging costs and improve economic benefits while ensuring packaging effects, and can prevent damage to the edges of the rectangular body 400, thereby providing better protection effects.

[0076] It should be noted that the rectangular body 400 includes two first side walls 410 and two second side walls 420 that are arranged opposite to each other, the two first side walls 410 are arranged parallel to each other, the two second side walls 420 are arranged parallel to each other, and the first side wall 410 is perpendicular to the second side wall 420. Specifically, the rectangular body 400 can be a single object, or it can be composed of a plurality of overlapping objects. In this embodiment, the rectangular body 400 is taken as an example of a stack of ceramic bricks, and the packaging assembly 100 is used to package a stack of ceramic bricks for subsequent transportation.

[0077] The packaging component 100 includes two first packaging members and two second packaging members. The two first packaging members are arranged in parallel and spaced apart, and the two first packaging members are respectively wrapped around the two first side walls 410. The two second packaging members are arranged in parallel and spaced apart, and the two second packaging members are respectively wrapped around the two second side walls 420. Specifically, the first packaging member is perpendicular to the second packaging member, and a first packaging member, a second packaging member, another first packaging member and another second packaging member are connected end to end and together form a rectangle to simultaneously package the four side walls of the rectangular body 400. In this way, the packaging component 100 only packages the four side walls of the rectangular body 400, leaving the upper and lower surfaces of the rectangular body 400 partially exposed, which can effectively reduce the packaging area, reduce the packaging cost while ensuring the packaging effect, and improve the economic benefits.

[0078] The first package includes a first covering portion, a connecting portion, and a second covering portion connected in sequence. The first covering portion and the second covering portion are arranged in parallel and spaced apart, and are arranged opposite to each other on the two sides of the rectangular body 400. The connecting portion is attached to the outside of the first side wall 410, and the connecting portion is perpendicular to the first covering portion and the second covering portion at the same time. The first covering portion, the connecting portion, and the second covering portion work together to cover the first side wall 410 of the rectangular body 400. Specifically, the length of the first package is the same as the length of the first side wall 410, and a tongue is protruding from the end of the connecting portion. The tongue is perpendicular to the connecting portion, and the tongue extends into the second package and is attached to the second side wall 420. The connecting portion and the tongue work together to cover the edge between the first side wall 410 and the second side wall 420.

[0079] The second package includes a first shielding portion, a connecting portion, and a second shielding portion connected in sequence. The first shielding portion and the second shielding portion are arranged in parallel and spaced apart, and are arranged oppositely on the two sides of the rectangular body 400. The connecting portion is attached to the outside of the second side wall 420. The connecting portion is perpendicular to the first shielding portion and the second shielding portion at the same time. The first shielding portion, the connecting portion and the second shielding portion work together to cover the second side wall 420 of the rectangular body 400. Specifically, the length of the second package is the same as the length of the second side wall 420. A pressing tongue is protruding from the end of the first shielding portion. The pressing tongue includes a first pressing section and a second pressing section connected to each other. The first shielding portion, the first pressing section and the second pressing section are perpendicular to each other. The first pressing section is attached to the outside of the connecting portion, and the second pressing section is clamped between the inserting tongue and the connecting portion. The first pressing section and the second pressing section work together to cover the edge between the first side wall 410 and the second side wall 420.

[0080] Furthermore, by simultaneously covering the edge between the first side wall 410 and the second side wall 420 with the first package and the second package, the protection of the edge of the rectangular body 400 can be enhanced, and damage to the edge of the rectangular body 400 can be avoided, thereby achieving a better protection effect.

[0081] In this embodiment, the first covering portion and the first shielding portion are both arranged outside the top surface of the rectangular body 400, and the second covering portion and the second shielding portion are both arranged outside the bottom surface of the rectangular body 400, but it is not limited to this. In other embodiments, the first covering portion and the first shielding portion may also be both arranged outside the bottom surface of the rectangular body 400, and in this case, the second covering portion and the second shielding portion are both arranged outside the top surface of the rectangular body 400.

[0082] The first covering portion includes a first middle section and a first corner section connected to each other, and the first middle section and the first corner section are both attached to the top surface of the rectangular body 400. The first shielding portion includes a second middle section and a second corner section connected to each other, wherein the second middle section is attached to the top surface of the rectangular body 400, and the second corner section is attached to the outside of the first corner section, that is, the second corner section overlaps with the first corner section, and the pressing tongue is arranged at an end of the second corner section away from the second middle section, so as to realize the covering function of the pressing tongue.

[0083] In this embodiment, there are two first corner sections, which are relatively arranged at the two ends of the first middle section. There are two second corner sections and two pressing tongues, which are relatively arranged at the two ends of the second middle section, and each pressing tongue is arranged at a second corner section. One second corner section is attached to the outside of a first corner section of a first package, and the other second corner section is attached to the outside of a first corner section of another first package, so as to realize the reasonable arrangement of the two first packages and the two second packages, and facilitate the reliable packaging of the rectangular body 400.

[0084] Correspondingly, there are two tongues, which are arranged oppositely at the two ends of the connecting portion, one tongue extending into a second packaging component, and the other tongue extending into another second packaging component, so as to respectively cover the two edges between the first side wall 410 and the two second side walls 420 to enhance the protection effect.

[0085] In this embodiment, the specific structure of the second covering part is the same as the specific structure of the first covering part, and the specific structure of the second shielding part is the same as the specific structure of the first shielding part. One end of the second shielding part is attached to the outside of the second covering part of a first package, and the other end is attached to the outside of the second covering part of another first package, which will not be repeated here.

[0086] Preferably, the first package is made by folding a first paperboard 110, and the first paperboard 110 is provided with a plurality of first folds 115 folded to form a first covering portion, a connecting portion, and a second covering portion. The first paperboard 110 is divided into the first covering portion, the connecting portion, and the second covering portion by folding, which is easy to form and has low production cost. Correspondingly, the second package is made by folding a second paperboard 120, and the second paperboard 120 is provided with a plurality of second folds 125 folded to form a first shielding portion, a connecting portion, and a second shielding portion. The second paperboard 120 is divided into the first shielding portion, the connecting portion, and the second shielding portion by folding, which is easy to form and has low production cost.

[0087] Furthermore, since both the first package and the second package are made of paperboard, the shaping effect is poor, so the relative position of the first package and the second package is fixed by bonding to prevent the first package and the second package from loosening and improve the packaging shaping effect. Specifically, the first covering part is bonded to the first shielding part, and the second covering part is bonded to the second shielding part to simultaneously fix the relative position of the two first packages and the two second packages, thereby improving the reliability of packaging and ensuring the packaging effect.

[0088] In this embodiment, the first package and the second package are both made of cardboard material, but it is not limited to this. In other embodiments, the first package and the second package can also be made of plastic material, and the material of the first package and the second package is not specifically limited.

[0089] In a second aspect, an embodiment of the present invention provides a packaging method, which is applied to the above-mentioned packaging assembly 100. The packaging assembly 100 includes the following steps:

[0090] Step S110: Processing a first paperboard 110 and a second paperboard 120, wherein the first paperboard 110 includes a first plate 111, a second plate 112 and a third plate 113 connected in sequence, an insert block 114 is protruding from the end of the second plate 112, and the second paperboard 120 includes a fourth plate 121, a fifth plate 122 and a sixth plate 123 connected in sequence, a pressing block 124 is protruding from the end of the fourth plate 121, and the pressing block 124 includes a first pressure strip 1241 and a second pressure strip 1242 connected to each other.

[0091] It should be noted that, in step S110, the first paperboard 110 and the second paperboard 120 are cut so that the first paperboard 110 and the second paperboard 120 form a specific shape, so as to facilitate the subsequent folding of the first paperboard 110 into a first package, and facilitate the subsequent folding of the second paperboard 120 into a second package. Specifically, for the first paperboard 110, the first plate 111, the second plate 112 and the third plate 113 are located on the same plane, the first plate 111 forms a first covering portion after folding, the second plate 112 forms a connecting portion after folding, the third plate 113 forms a second covering portion after folding, and the insert block 114 forms an insert tongue after folding. For the second paperboard 120, the fourth plate 121, the fifth plate 122 and the sixth plate 123 are located on the same plane, the fourth plate 121 forms a first shielding portion after folding, the fifth plate 122 forms a connecting portion after folding, the sixth plate 123 forms a second shielding portion after folding, and the pressing block 124 forms a pressing tongue after folding (wherein the first pressing strip 1241 forms a first pressing section after folding, and the second pressing strip 1242 forms a second pressing section after folding).

[0092] Further, in step S110, the first paperboard 110 and the second paperboard 120 are creasing or punching, so that the first paperboard 110 forms a plurality of first folds 115, and the second paperboard 120 forms a plurality of second folds 125. Specifically, for the first paperboard 110, there is a first fold 115 between the first plate 111 and the second plate 112, and there is a first fold 115 between the second plate 112 and the third plate 113, so as to facilitate folding the first paperboard 110. For the second paperboard 120, there is a second fold 125 between the fourth plate 121 and the fifth plate 122, there is a second fold 125 between the fifth plate 122 and the sixth plate 123, and there is a second fold 125 between the fourth plate 121 and the pressing block 124, so as to facilitate folding the second paperboard 120.

[0093] Step S120 : applying glue on the first plate 111 and / or the fourth plate 121 to facilitate bonding of the first plate 111 and the fourth plate 121 .

[0094] In this embodiment, in step S120, glue is dispensed at both ends of the first plate 111 (positions corresponding to the two first corner sections of the first covering portion) to facilitate the subsequent bonding of the fourth plate 121 to the first plate 111. Specifically, glue is dispensed on the first plates 111 of the two first paperboards 110 at the same time to facilitate the bonding of the two second paperboards 120 to the two first paperboards 110 at the same time. However, this is not limited to this. In other embodiments, glue can be dispensed at both ends of the fourth plate 121 alone, or glue can be dispensed at both ends of the first plate 111 and both ends of the fourth plate 121 at the same time.

[0095] Step S130 : overlap the two first paperboards 110 relative to each other on the rectangular body 400 , so that the second plate 112 and the third plate 113 are both protruded from the first side wall 410 .

[0096] It should be noted that, in step S130, two first paperboards 110 are placed on the top surface of the rectangular body 400 at the same time, and the two first paperboards 110 are arranged opposite to each other on both sides of the rectangular body 400, and each first paperboard 110 protrudes from a first side wall 410. Specifically, the first plate 111 is completely attached to the top surface of the rectangular body 400, and the second plate 112 and the third plate 113 both protrude from the first side wall 410 and are suspended.

[0097] In this embodiment, the two first paperboards 110 are overlapped on the top surface of the rectangular body 400 to facilitate the subsequent folding of the first paperboards 110 downwards, but it is not limited to this. In other embodiments, the two first paperboards 110 can also be overlapped on the bottom surface of the rectangular body 400 to facilitate the subsequent folding of the first paperboards 110 upwards, which can also achieve the same packaging effect.

[0098] Step S140 : overlap the two second paperboards 120 relative to the rectangular body 400 , so that the fifth plate 122 and the sixth plate 123 are both protruded from the second side wall 420 , the fourth plate 121 is partially attached to the first plate 111 , and the pressing block 124 is at least partially attached to the second plate 112 .

[0099] It should be noted that, in step S140, two second paperboards 120 are placed on the top surface of the rectangular body 400 at the same time, and the two second paperboards 120 are arranged on both sides of the rectangular body 400 opposite to each other, and each second paperboard 120 protrudes a second side wall 420. Specifically, the middle part of the fourth plate 121 is attached to the top surface of the rectangular body 400, the two ends of the fourth plate 121 are respectively attached to the first plates 111 of the two first paperboards 110, the pressing block 124 is attached to the second plate 112 (the first pressing strip 1241 in the pressing block 124 is attached to the second plate 112, and the second pressing strip 1242 in the pressing block 124 is attached to the insert block 114), and the fifth paperboard and the sixth paperboard both protrude from the second side wall 420 and are suspended.

[0100] Furthermore, in step S140 , since both ends of the fourth plate 121 are respectively attached to the first plates 111 of the two first paperboards 110 , and the first plates 111 are provided with adhesive, the fourth plate 121 and the first plates 111 can be bonded and fixed.

[0101] In this embodiment, the two second paperboards 120 are overlapped on the top surface of the rectangular body 400 to facilitate the subsequent folding of the second paperboards 120 downwards, but it is not limited to this. In other embodiments, the two second paperboards 120 can also be overlapped on the bottom surface of the rectangular body 400 to facilitate the subsequent folding of the second paperboards 120 upwards, which can also achieve the same packaging effect.

[0102] Step S150 : Press the first plate 111 and the fourth plate 121 onto the rectangular body 400 .

[0103] It should be noted that in step S150, the first plate 111 and the fourth plate 121 are pressed against the top surface of the rectangular body 400 to prevent the first paperboard 110 and the second paperboard 120 from shifting during the subsequent folding process, avoiding folding misalignment and ensuring the packaging effect.

[0104] Furthermore, in step S150, the fourth plate 121 is tightly pressed onto the first plate 111, so that the glue between the first plate 111 and the fourth plate 121 can be evenly pressed, and the relative position between the first plate 111 and the fourth plate 121 is fixed before the glue dries, thereby ensuring the bonding and fixing effect.

[0105] Step S160 : fold the second plate 112 and the pressing block 124 relative to the first plate 111 at the same time, and fold the third plate 113 relative to the second plate 112 , so that the first plate 111 and the third plate 113 are relatively arranged outside two surfaces of the rectangular body 400 , and the second plate 112 is attached to the outside of the first side wall 410 .

[0106] It should be noted that in step S160, firstly, the second plate 112 is folded 90 degrees relative to the first plate 111, and the pressing block 124 is folded 90 degrees relative to the fourth plate 121, so that the second plate 112 is completely attached to the first side wall 410. In this process, the insert block 114 is folded along with the second plate 112, and always maintains an attached state with the second pressure strip 1242 in the pressing block 124; then, the third plate 113 is folded 90 degrees relative to the second plate 112, so that the third plate 113 is completely attached to the bottom surface of the rectangular body 400. In this way, the second plate 112 is perpendicular to the first plate 111 and the third plate 113 at the same time, and the first plate 111, the second plate 112 and the third plate 113 work together to cover the first side wall 410 of the rectangular body 400.

[0107] Step S170 : applying glue on the sixth plate 123 and / or the third plate 113 , so as to facilitate bonding of the sixth plate 123 and the third plate 113 .

[0108] In this embodiment, in step S170, glue is dispensed at both ends of the sixth plate 123 (positions corresponding to the two first corner sections of the second covering portion) to facilitate subsequent bonding of the sixth plate 123 to the third plate 113. Specifically, glue is dispensed on the sixth plates 123 of the two second paperboards 120 at the same time to facilitate bonding of the two second paperboards 120 to the two first paperboards 110 at the same time. However, this is not limited to this. In other embodiments, glue may be dispensed at both ends of the third plate 113 alone, or glue may be dispensed at both ends of the sixth plate 123 and both ends of the third plate 113 at the same time.

[0109] Step S180 : fold the insert block 114 relative to the second plate 112 , and fold the second pressure strip 1242 relative to the first pressure strip 1241 , so that the insert block 114 and the second pressure strip 1242 are sequentially attached to the outside of the second side wall 420 .

[0110] It should be noted that in step S180, the insert block 114 is folded 90 degrees relative to the second plate 112, and the second pressure strip 1242 is simultaneously folded 90 degrees relative to the first pressure strip 1241, so that the insert block 114 is completely attached to the second side wall 420, and the second pressure strip 1242 is attached to the outside of the insert block 114. At this time, the first cardboard 110 is folded to form a first package.

[0111] Step S190 : fold the fifth plate 122 relative to the fourth plate 121 , and fold the sixth plate 123 relative to the fifth plate 122 , so that the fourth plate 121 and the sixth plate 123 are disposed oppositely outside two surfaces of the rectangular body 400 , and the fifth plate 122 is attached to the outside of the second side wall 420 .

[0112] It should be noted that in step S190, firstly, the fifth plate 122 is folded 90 degrees relative to the fourth plate 121, so that the middle of the fifth plate 122 is attached to the second side wall 420, and the two ends of the fifth plate 122 are attached to the outside of the second pressure strips 1242 of the two second paperboards 120; then the sixth plate 123 is folded 90 degrees relative to the fifth plate 122, so that the middle of the sixth plate 123 is attached to the bottom surface of the rectangular body 400, and the two ends of the sixth plate 123 are attached to the third plates 113 of the two first paperboards 110, and the second paperboards 120 are folded to form a second package. In this way, the fifth plate 122 is perpendicular to the fourth plate 121 and the sixth plate 123 at the same time, and the fourth plate 121, the fifth plate 122 and the sixth plate 123 work together to cover the second side wall 420 of the rectangular body 400.

[0113] Furthermore, in step S190 , since both ends of the sixth plate 123 are respectively attached to the third plates 113 of the two first paperboards 110 and adhesive is provided on the sixth plate 123 , the sixth plate 123 and the third plate 113 can be bonded and fixed.

[0114] Please refer to Figures 5 to 13 In a third aspect, an embodiment of the present invention provides a packaging device 200 for implementing the above-mentioned packaging method, which is described by taking the first paperboard 110 and the second paperboard 120 overlapped on the top surface of the rectangular body 400 as an example.

[0115] The packaging device 200 includes a frame 210 and a first conveying mechanism 220, a second conveying mechanism 230, a first folding mechanism 240, a second folding mechanism 250, a third folding mechanism 260, a pressing mechanism 270 and a glue dispensing mechanism 280 installed on the frame 210. The first conveying mechanism 220 is used to overlap the two first paperboards 110 relative to the rectangular body 400, so that the second plate 112 and the third plate 113 are both protruding from the first side wall 410, that is, the first conveying mechanism 220 is used to implement step S130; the second conveying mechanism 230 is used to overlap the two second paperboards 120 relative to the rectangular body 400, so that the fifth plate 122 and the sixth plate 123 are both protruding from the second side wall 420, and the fourth plate 121 is partially attached to the first plate 1 ... The pressing block 124 is attached to the second plate 112, that is, the second conveying mechanism 230 is used to implement step S140; the pressing mechanism 270 is used to press the first plate 111 and the fourth plate 121 to the top surface of the rectangular body 400, that is, the pressing mechanism 270 is used to implement step S150; the first folding mechanism 240 is used to fold the second plate 112 and the pressing block 124 relative to the first plate 111 at the same time, and fold the third plate 113 relative to the second plate 112, so that the first plate 111 and the third plate 113 are relative to each other. The second plate 112 is arranged outside the two surfaces of the rectangular body 400, and the second plate 112 is attached to the outside of the first side wall 410, that is, the first folding mechanism 240 is used to implement step S160; the second folding mechanism 250 is used to fold the plug block 114 relative to the second plate 112, and at the same time fold the second pressure strip 1242 relative to the first pressure strip 1241, so that the plug block 114 and the second pressure strip 1242 are sequentially attached to the outside of the second side wall 420, that is, the second folding mechanism 250 is used to implement step S180; the glue dispensing mechanism 280 is used to Glue is dispensed on the first plate 111 or the sixth plate 123, that is, the glue dispensing mechanism 280 is used to implement step S120 and step S170; the third folding mechanism 260 is used to fold the fifth plate 122 relative to the fourth plate 121, and to fold the sixth plate 123 relative to the fifth plate 122, so that the fourth plate 121 and the sixth plate 123 are relatively arranged outside the two sides of the rectangular body 400, and the fifth plate 122 is attached to the outside of the second side wall 420, that is, the third folding mechanism 260 is used to implement step S190.

[0116] The first conveying mechanism 220 includes a storage unit 221, a transfer unit 222 and a sheet feeding unit 223. The transfer unit 222 is connected between the storage unit 221 and the sheet feeding unit 223. The storage unit 221 is used to store the first paperboard 110 after processing, the transfer unit 222 is used to transfer the first paperboard 110 in the storage unit 221 to a preset position, and the sheet feeding unit 223 is used to transport the first paperboard 110 at the preset position to the rectangular body 400, so that the first paperboard 110 overlaps the top surface of the rectangular body 400, which is convenient for subsequent folding.

[0117] The transfer unit 222 includes a first transfer module 2221 and a second transfer module 2222. The first transfer module 2221 is used to take out the first paperboard 110 in the storage unit 221 and translate and lift it to a preset height to achieve the first transfer; the second transfer module 2222 is used to translate and pull the first paperboard 110 lifted to the preset height onto the paper placing platform 2223, so that the first paperboard 110 reaches a preset position to achieve the second transfer, at which time the first paperboard 110 is arranged parallel to the first side wall 410 of the rectangular body 400; thereafter, the sheet feeding unit 223 translates and transports the first paperboard 110 at the preset position to the rectangular body 400, so that the first paperboard 110 overlaps the top surface of the rectangular body 400, which is convenient for subsequent folding.

[0118] In this embodiment, there are two first conveying mechanisms 220, each of which is used to convey one first paperboard 110. The two first conveying mechanisms 220 are respectively disposed on both sides of the two ends of the conveying mechanism 290 and are arranged in a cross shape to avoid mutual interference.

[0119] The sheet feeding unit 223 includes a mechanical arm 2231 and a vacuum suction cup 2232. The vacuum suction cup 2232 is installed on the mechanical arm 2231, and the vacuum suction cup 2232 is used to absorb the first paperboard 110, and the mechanical arm 2231 is used to drive the vacuum suction cup 2232 to move. The mechanical arm 2231 and the vacuum suction cup 2232 work together to first suck up the first paperboard 110 at a preset position, and then drive the first paperboard 110 to move onto the rectangular body 400, and then place the first paperboard 110 on the top surface of the rectangular body 400.

[0120] It should be noted that the conveying principle of the second conveying mechanism 230 is similar to that of the first conveying mechanism 220, except that the conveying direction is different. The main difference is that the second conveying mechanism 230 does not need to perform a second transfer, which will not be described in detail here. In this embodiment, there are two second conveying mechanisms 230, each of which is used to convey one second cardboard 120, and the two second conveying mechanisms 230 are symmetrically arranged on both sides of the conveying mechanism 290 to avoid mutual interference.

[0121] Furthermore, the first conveying mechanism 220 and the second conveying mechanism 230 adopt a compact frame design, which reduces the space occupied by the equipment and facilitates efficient transportation. The first conveying mechanism 220 and the second conveying mechanism 230 cooperate to realize the step-by-step implementation of the paper picking and paper placing actions of the first paperboard 110 and the second paperboard 120, and avoid mutual influence with the paper stacking action, which is conducive to the synchronous or partial synchronous implementation of the paper picking, paper placing, and paper stacking actions. Compared with the method of sequentially implementing the paper picking, paper placing, and paper stacking actions, the time is greatly reduced, and the packaging efficiency is effectively improved. In addition, the cooperation of the two first conveying mechanisms 220 and the two second conveying mechanisms 230 can realize simultaneous paper picking from four directions, and adjust the paper placing position according to the size of the rectangular body 400, so as to realize the packaging of rectangular bodies 400 of different sizes, thereby improving the compatibility of the equipment.

[0122] The first folding mechanism 240 includes a folding unit 241 and an inner folding unit 242 which are arranged at intervals. The folding unit 241 is used to fold the second plate 112 and the pressing block 124 downward along the first side wall 410 so that the second plate 112 and the pressing block 124 are arranged perpendicular to the first plate 111, and the first folding is completed. During this process, the second plate 112 is folded 90 degrees relative to the first plate 111, and the pressing block 124 is folded 90 degrees relative to the fourth plate 121, so that the second plate 112 is completely attached to the first side wall 410, and the insert block 114 is folded along with the second plate 112, and always maintains an attached state with the second pressing strip 1242 in the pressing block 124. The inner folding unit 242 is used to fold the third panel 113 inward along the bottom surface of the rectangular body 400 so that the third panel 113 is arranged perpendicular to the second panel 112, completing the second folding. During this process, the third panel 113 is folded 90 degrees relative to the second panel 112 so that the third panel 113 is completely attached to the bottom surface of the rectangular body 400.

[0123] The inner folding unit 242 includes a first driving member 2421, a lifting frame 2422, a second driving member 2423 and a push plate 2424. The first driving member 2421 is connected to the lifting frame 2422, the second driving member 2423 is installed on the lifting frame 2422 and connected to the push plate 2424, the first driving member 2421 is used to drive the lifting frame 2422 to rise or fall, so as to adjust the height of the push plate 2424 to ensure the folding accuracy, and the second driving member 2423 is used to drive the third plate 113 to move through the push plate 2424 to achieve the folding function.

[0124] In this embodiment, in order to ensure the packaging effect and improve the packaging efficiency, the folding unit 241 and the pressing mechanism 270 are both integrated and installed on the mechanical arm 2231. The mechanical arm 2231 can synchronously drive the vacuum suction cup 2232, the folding unit 241 and the pressing mechanism 270 to move, that is, the sheet feeding function (step S130) of the first paperboard 110, the folding function (the first folding in step S160) of the first paperboard 110, and the pressing function (step S150) of the first paperboard 110 and the second paperboard 120 are integrated into one, which is conducive to quickly pressing (step S150) after the sheet feeding (step S130 and step S140) of the first paperboard 110 and the second paperboard 120 is completed, and is conducive to quickly folding the first paperboard 110 (the first folding in step S160) after the pressing (step S150) is completed, thereby improving the packaging efficiency. In addition, the various components are closely arranged, so that the packaging device 200 has a compact structure and can meet the requirements of fast packaging of rectangular bodies 400 of different sizes. However, it is not limited to this. In other embodiments, the folding unit 241, the pressing mechanism 270 and the sheet feeding unit 223 can be set separately, or any two of them can be integrated. There is no specific limitation on the setting method of the folding unit 241, the pressing mechanism 270 and the sheet feeding unit 223.

[0125] Preferably, the first folding mechanism 240 further includes an adjustment unit 243. There are two inner folding units 242, which are arranged opposite to each other and can be slidably mounted on the adjustment unit 243. The two inner folding units 242 work together to simultaneously realize the folding function of the two first paperboards 110, thereby improving the folding efficiency and thus improving the packaging efficiency. Specifically, the adjustment unit 243 is used to drive the two inner folding units 242 to move closer to or away from each other, so as to adjust the spacing between the two inner folding units 242, so that the two inner folding units 242 can fold the rectangular bodies 400 of different sizes, thereby improving the versatility of the packaging device 200.

[0126] It should be noted that the folding principle of the folding unit 241 is similar to that of the inner folding unit 242, except that the folding direction is different, which will not be described here. In addition, the number of the folding units 241 is also two, and the two folding units 241 work together to simultaneously realize the folding function of the two first paperboards 110, thereby improving the folding efficiency. In addition, the number of the sheet feeding units 223 and the clamping mechanism 270 is two, and the mechanical arm 2231 in each sheet feeding unit 223 can drive a clamping mechanism 270 and a folding unit 241 to move. On the one hand, the two folding units 241 can be moved closer to or farther from each other, thereby adjusting the distance between the two folding units 241, so that the two folding units 241 can fold the rectangular bodies 400 of different sizes; on the other hand, the two clamping mechanisms 270 can be moved closer to or farther from each other, thereby adjusting the distance between the two clamping mechanisms 270, so that the two clamping mechanisms 270 can clamp the rectangular bodies 400 of different sizes, thereby improving the versatility of the packaging device 200.

[0127] The second folding mechanism 250 includes a third driving member 251, a lifting seat 252, a fourth driving member 253 and a folding plate 254. The third driving member 251 is connected to the lifting seat 252, the fourth driving member 253 is installed on the lifting seat 252 and connected to the folding plate 254, the third driving member 251 is used to drive the lifting seat 252 to rise or fall, so as to adjust the height of the folding plate 254 to ensure the folding accuracy, and the fourth driving member 253 is used to synchronously drive the insertion block 114 and the second pressure strip 1242 to move through the folding plate 254 to achieve the folding function.

[0128] It should be noted that the folding principle of the third folding mechanism 260 is similar to that of the first folding mechanism 240, except that the folding directions are different. The first folding mechanism 240 is first folded downward along the first side wall 410, and then folded inward along the bottom surface of the rectangular body 400, while the third folding mechanism 260 is first folded downward along the second side wall 420, and then folded inward along the bottom surface of the rectangular body 400, which will not be repeated here.

[0129] In this embodiment, in order to ensure the packaging effect and improve the packaging efficiency, the folding unit in the third folding mechanism 260 (similar to the folding unit 241 in the first folding mechanism 240) is integrated into the second folding mechanism 250, that is, the folding function (step S180) of the insert block 114 and the second pressure strip 1242 and the folding function (the first folding in step S190) of the second paperboard 120 are integrated into one body, which is conducive to quickly folding the second paperboard 120 (the first folding in step S190) after the folding (step S180) of the insert block 114 and the second pressure strip 1242 is completed, thereby improving the packaging efficiency. In addition, the various components are closely arranged, so that the packaging device 200 has a compact structure and can meet the requirements for fast packaging of rectangular bodies 400 of different sizes and specifications. However, it is not limited to this. In other embodiments, the folding unit and the second folding mechanism 250 can also be separately arranged, and the arrangement method of the folding unit and the second folding mechanism 250 is not specifically limited.

[0130] Specifically, the third folding mechanism 260 includes a pressing plate 261. The pressing plate 261 is connected to the lifting seat 252. The pressing plate 261 is arranged above the folding plate 254 in parallel and at intervals. The third driving member 251 can synchronously drive the pressing plate 261 and the folding plate 254 to rise and fall through the lifting seat 252. During the folding process, the fourth driving member 253 first drives the folding plate 254 to retract; then the entire third folding mechanism 260 moves to the side of the rectangular body 400, so that the pressing plate 261 is arranged above the second paperboard 120, and the folding plate 254 is arranged outside the second side wall 420; then the fourth driving member 253 drives the folding plate 254 to extend, so as to fold the insert block 114 and the second pressure strip 1242 to fit the second side wall 420. At this time, the pressing plate 261 remains stationary, and the folding plate 254 is extended and located at the pressing plate 114. Then the third driving member 251 is used to synchronously drive the pressing plate 261 and the folding plate 254 to descend. During this process, the pressing plate 261 folds the second paperboard 120 downward (folds the fifth board 122 90 degrees relative to the fourth board 121), so that the fifth board 122 is partially attached to the second side wall 420, and the insert block 114 and the second pressure strip 1242 are clamped between the fifth board 122 and the second side wall 420, and the folding plate 254 gradually separates from the second pressure strip 1242 from top to bottom. In this way, the folding of the insert block 114 and the second pressure strip 1242 and the folding of the second paperboard 120 are completed successively, and the interval time is very short, which further improves the packaging efficiency.

[0131] In an optional embodiment, the size of the rectangular body 400 is relatively large, that is, the length of the fifth plate 122 is relatively long, and the packaging device 200 further includes a fourth folding mechanism 310. In the process of folding the fifth plate 122 relative to the fourth plate 121 (the first folding in step S190), the pressing plate 261 of the third folding mechanism 260 presses the end of the fifth plate 122 downward, and the fourth folding mechanism 310 assists in pressing the middle of the fifth plate 122 downward. The fourth folding mechanism 310 and the pressing plate 261 of the third folding mechanism 260 work together to ensure that the entire fifth plate 122 is folded downward synchronously, to avoid the fifth plate 122 from being twisted and deformed, to ensure the packaging effect, and to improve the flatness of the packaging of the large-sized rectangular body 400.

[0132] Preferably, the packaging device 200 further includes a conveying mechanism 290.
