[0002] At present, in the field of product packaging, especially in the field of packaging involving paper box-type outer packaging, manual folding and buckling of paper boxes are usually still used, which is not only inefficient, but also affects the sanitary quality of the product. Especially when packaging medical gloves or other products with high requirements for hygiene and safety, manual labor is obviously a safety barrier. In the prior art, there are also automated paper box packaging machines, such as the invention patent with the patent number "201811182041.1" and the patent name "An automatic cartoning machine and its use method". Although it also realizes the automatic boxing of products, its paper box is ultimately sealed by hot melt spraying. The paper box is ultimately only used once and cannot be reused by consumers; and the adhesive seal will also cause secondary pollution to the hygiene of the products in the box.

DETAILED DESCRIPTION

[0030] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] In a specific embodiment of the present invention, Figures 1A to 3 As shown, in the specific embodiment of the present invention, a rectangular paper box packaging box 200 is taken as an example to describe the structure of each mechanism in the entire product box packaging production line 100. The two openings of the packaging box 200, namely the first opening 201 and the second opening 202, can be the same or different structures. In the specific embodiment of the present invention, the two openings are mirror-symmetrical as an example; the rectangular packaging box has four obvious folds 203, so that under the action of the folds 203, the packaging box 200 can be as follows: Figure 1A and 1B In the folded plane state shown in FIG. 1 , the folded plane state can also be supported by the fold 203 as an edge to form a cubic structure under the action of external force. Figure 2A and 2B As shown, the packaging box 200 has two adjacent first side surfaces 204 and second side surfaces 205 as the first surface in a plane state, and the other two adjacent third side surfaces 206 and fourth side surfaces 207 constitute the second surface of the packaging box 200 in a plane state; the first opening 201 and the second opening 202 corresponding to the packaging box are taken as examples of both having two buckles, an upper cover and a lower cover, but it is obvious that there may also be only an upper cover and a lower cover or other types, which will not be described in detail here. In order to clearly indicate the folds of the packaging box 200, Figures 1A to 3 In the figure, each fold is represented by a dotted line. Figure 2A for Figure 1A A schematic diagram of the first side of the package box 200 in a flat state formed by pressing down the fold 203 at the upper left corner after being turned upward from the first opening; Figure 2B for Figure 1A A schematic diagram of the second side of the packaging box 200 in a flat state formed after the fold 203 at the upper left of the middle three-dimensional packaging box 200 is pressed down;

[0032] like Figures 4A to 9 As shown, in a specific embodiment of the present invention, a product box packaging production line 100 includes a product conveying mechanism 1, a box preforming mechanism 2, a box fastening mechanism 3 and a box transfer mechanism 4; the box preforming mechanism 2 preforms a box 200 in a planar state into a box 200 in a three-dimensional state, and the box transfer mechanism 4 conveys the box 200 in a three-dimensional state to the box fastening mechanism 3, and the box 200 has a first opening 201 and a second opening 202 that are relatively arranged; the box fastening mechanism 3 seals the first opening 201 of the box 200, and the box transfer mechanism 4 conveys the box 200 to the product conveying mechanism 1, and the product conveying mechanism 1 conveys the product into the box 200; the box transfer mechanism 4 again transports the box containing the product inside to the box fastening mechanism 3, and the box fastening mechanism 3 seals the second opening 202 of the box 3 containing the product inside, thereby completing the product box packaging process.

[0033] In the state where the first opening 201 and the second opening 202 are sealed by the upper cover 2013, the lower cover 2014 and the two buckles (2011, 2012) that are buckled with each other, in the specific embodiment of the present invention, the first opening 201 and the second opening 202 of the packaging box 200 are sealed without glue by the packaging box buckling mechanism 3. Thus, the packaging box 200 is detachable and the secondary pollution caused by glue coating is avoided, and the packaging box can be reused by the user after being disassembled.

[0034] In a specific embodiment of the present invention, Figure 4A (shown in FIG. 1 ), the packaging box preforming mechanism 2 includes a packaging box storage platform 21, a transport mechanism 22 and a straightening mechanism 23 which are arranged in sequence; Figure 1A The packaging boxes 200 in the folded plane state are neatly arranged and placed on the packaging box storage platform 21, and the transport mechanism 22 transports the packaging boxes 200 on the packaging box storage platform 21 to the straightening mechanism 23; Figure 5 and 6 As shown, the transport mechanism 22 includes a rotating shaft 221 and a suction cup rod 222 driven to rotate by the rotating shaft 221, the top of the suction cup rod 222 has a bending portion 223, and the front end of the bending portion 223 is provided with a first suction cup 224, the first suction cup 224 sucks the first side surface 204 of the packaging box 200, and the motor or other driving mechanism drives the rotating shaft 221 to rotate, so that the packaging box 200 is sucked to the position of the straightening mechanism 23 under the drive of the rotating shaft 221.

[0035] like Figure 5 and 6As shown, the straightening mechanism 23 includes a straightening platform 231, a clamping baffle 230 located at the front side of the straightening platform 231, and a straightening arc plate 232 located at the rear side of the straightening platform 231, and the straightening arc plate 232 is backed by the straightening platform 231; in the specific embodiment of the present invention, preferably, the straightening platform 231 is arranged at the position of the packaging box 200 in a flat state when it is turned over to a horizontal state, that is, at this time, the first side surface 204 sucked by the first suction cup 224 faces directly downward, and the second side surface 205 adjacent to the first side surface 204 will first contact the straightening arc plate 231 during the turning process. 2, and there is a first fold 208 between the first side 204 and the second side 205. Therefore, with the help of the arc-shaped back of the straightening arc plate 232, during the rotation and descent of the packaging box 200, the second side 205 of the packaging box 200 is blocked by the back of the straightening arc plate 232 and gradually folded upward along the first fold 208 to straighten. The second side 205 will eventually lean against the back of the straightening arc plate 232 and stand up. After that, the first side 204 is placed on the straightening platform 231, and the packaging box 200 finally fully realizes a cubic structure under the action of multiple folds. This realizes that the packaging box 200 in a flat folded state becomes a three-dimensional state for the first time, such as Figure 1A and 1B As shown, to facilitate the next program action.

[0036] Preferably, in a specific embodiment of the present invention, Figure 5 As shown, the bending portion 223 can be an inverted L-shape, and the first suction cup 224 is arranged to face the first side surface 204, so that the bending portion 223 can just reach the straightening platform 231 after flipping 90 degrees. During this process, the second side surface 205 will be blocked and straightened by the back side of the straightening arc plate 232.

[0037] In a specific embodiment of the present invention, Figure 4A and 4B As shown, the packaging box transfer mechanism 4 preferably includes a guide rail 41 and a second suction cup 42 driven by the guide rail 41. The suction cup sucks the three-dimensional packaging box 200 into the subsequent packaging box folding mechanism 3 to engage the first opening 201. Obviously, other mechanisms can also be used to achieve the transfer of the packaging box 200.

[0038] In a specific embodiment of the present invention, Figures 1A to 3 As shown, the first opening 201 of the packaging box 200 has a left piece buckle 2011 and a right piece buckle 2012 that are relatively arranged. The outer side of the left piece buckle 2011 has a left slot 20111 opened from the upper edge downward, and the outer side of the right piece buckle 2012 has a right slot 20121 opened from the lower edge upward. The right slot 20121 is inserted into the left slot 20111, thereby realizing the combination of the left piece buckle 2011 and the right piece buckle 2012.

[0039] Thus, the packaging box fastening mechanism 3 includes a fastening cover fastening mechanism 31 for fastening the left plate fastener 2011 and the right plate fastener 2012. Figure 7 As shown, the snap-on cover body snap-on mechanism 31 includes a snap-on platform 311 , a left push plate 313 , a right push plate 314 , a tilt push plate 316 and a straightening push plate 317 .

[0040] The packaging box transfer mechanism 4 places the packaging box 200 in a three-dimensional state on the buckling platform 311, and the buckling platform 311 is also preferably provided with a clamping mechanism 312, such as Figure 7 As shown, the clamping baffle 312 can clamp the rear end of the packaging box 200, so that the buckling platform 311 clamps the packaging box 200 in a three-dimensional state, so as to facilitate the sealing action of the first opening 201 of the packaging box 200 at the front end position near the first opening 201; wherein, the left push plate 313 is located on the left side of the left piece buckle 2011, and the right push plate 314 is located on the right side of the second side surface 205 of the packaging box 200; the inclined push plate 316 is located on the left side of the packaging box 200, and the straightening push plate 317 is located on the right side of the packaging box 200. In the specific embodiment of the present invention, the inclined push plate 316 is used to push from top to bottom. Taking the example of applying force downward on the edge (fold 203) between the left side (i.e., the fourth side 207) and the top side (i.e., the third side 206) of the packaging box 200, the straightening push plate 317 applies force downward on the left piece buckle 201, thereby driving the packaging box 200 to tilt slightly to the right; at this time, the left push plate 313 pushes the left piece buckle 201 from left to right to fold inward, and the right push plate 314 pushes the right piece buckle 2012 from right to left to fold inward, and because the packaging box 200 is in a tilted state, after the right slot 20121 and the left slot 20111 are folded inward, the two are in an up-and-down tilted opposing state, such as Figure 3 The packaging box 200 is shown in a slightly tilted state. The right side (also the second side 205 in the specific embodiment of the present invention) of the packaging box 200 is pushed by the straightening push plate 317 to insert the right slot 20121 into the left slot 20111. Thus, the automatic engagement of the two buckles is fully automated.

[0041] like Figure 8As shown, both the tilting push plate 316 and the straightening push plate 317 are driven by the first servo motor 315 to rotate or tilt at a certain angle and apply force; and after the straightening push plate 317 pushes the right side (second side 205) of the packaging box 200, the straightening push plate 317 will continue to apply the set thrust to the right side 205 of the packaging box 200, and after receiving the reverse thrust of the packaging box 200, the straightening push plate 314 will feed back the magnitude of the reverse thrust to the control unit (not shown here), and the control unit determines whether the left piece buckle 2011 and the right piece buckle 2012 are accurately combined according to the value of the reverse thrust. If the reverse thrust is less than the value of the reverse thrust set by the control unit, it is assumed that the left piece buckle 2011 and the right piece buckle 2012 are not combined, and the control unit will control the alarm unit to alarm or the display unit to display the current status, etc., thereby avoiding the erroneous operation of the two buckles not being fastened to affect the actions of subsequent programs.

[0042] In a specific embodiment of the present invention, the bottom of the left push plate 313 and the right push plate 314 respectively have push plate grooves 3131 and 3141, and the push plate grooves 3131 and 3141 are both arranged on the push plate rail 3132. The left push plate 313 and the right push plate 314 can be driven to move by the third servo motor 3133 and the fourth servo motor 3143 respectively, so as to stably fold the left piece buckle 2011 and the right piece buckle 2012.

[0043] like Figures 1A to 3 As shown, when the first opening 201 of the packaging box 200 has an upper cover 2013 and a lower cover 2014 that are opposed to each other, the buckle cover body buckling mechanism 31 also includes an upper opening mechanism 37 and a lower opening mechanism 38. The upper opening mechanism 37 props up the upper cover 2013 outward, and the lower opening mechanism 38 presses the lower cover 2014 downward to be horizontal or in other states, so that the buckling process of the left sheet buckle 2011 and the right sheet buckle 2012 will not be affected by the upper cover 2013 and the lower cover 2014. Preferably, the upper opening mechanism 37 can be driven by an electric cylinder to move the height to adapt to paper boxes of different heights, and the lower opening mechanism 38 can be driven by a pneumatic cylinder to achieve stable movement forward and backward to press the lower cover 2014. After the upper cover 2013 and the lower cover 2014 are propped open, operating space can be reserved for the buckling of the left sheet buckle 2011 and the right sheet buckle 2012 of the packaging box 200. Figures 1A to 3As shown, preferably, the first opening 201 of the packaging box 200 has an upper cover 2013, and the outer edge of the upper cover 2013 is connected to a pre-folded edge 2017 inserted into the packaging box 200 through a second fold 2015; thus, the packaging box buckling mechanism 3 includes a first flip-type cover folding mechanism 32 for buckling the upper cover 2013 and inserting the pre-folded edge 2017 into the packaging box 200, as shown in Figure 8, the first flip-type cover folding mechanism 32 includes a first auxiliary shaft 321, a second auxiliary shaft 322, a first folding mechanism 323, a pushing plate 324 and a first folding platform 325 for clamping the packaging box 200 in a three-dimensional state; the first auxiliary shaft 321 is driven by the first driving mechanism 326 to press the upper cover 2013 downward on the outer side of the upper cover 2013, wherein the first driving mechanism 326 can be an electric cylinder; Driven by the second driving mechanism 327, the second auxiliary shaft 322 extends from one side of the upper cover to the bottom side of the pre-folded edge 2017 and is located above the second fold 2015, wherein the second driving mechanism 327 can be a cylinder; the first auxiliary shaft 321 and the second auxiliary shaft 322 are arranged horizontally; the first folding mechanism 323 is arranged on the front side of the first opening 201, and the first folding mechanism 323 pushes the pre-folded edge 2017, and the pre-folded edge 2017 is folded inward from the second fold 2015 under the action of the first folding mechanism 323 and the second auxiliary shaft 322; the pushing plate 324 is located above the first folding mechanism 323, and the pushing plate 324 pushes the outer side surface of the upper cover 2013 and moves toward the inside of the packaging box 200, and the pre-folded edge 2017 is inserted into the packaging box 200 driven by the upper cover 2013 to complete the buckling of the upper cover 2013.

[0044] Preferably, in order to prevent the upper cover 2013 from failing to be truly fastened due to misoperation, a first suction cup structure 3241 may be provided on the outer surface of the push plate 324. After the pre-folded edge 2017 is fastened, the first suction cup structure 3241 of the push plate 324 adsorbs the outer side surface of the upper cover 2013 through the air pump control. The negative pressure value generated by the first suction cup structure 3241 adsorbing the upper cover 2013 will be fed back to the control unit. The control unit compares the set negative pressure value with the feedback negative pressure value to determine whether the upper cover 2013 is fastened. If the feedback negative pressure value is higher than the negative pressure value set by the control unit, it indicates that the upper cover 2013 is not fastened. The control unit will control the alarm unit to alarm or the display unit to display the current status, etc., thereby preventing the upper cover 2013 from not being fastened and affecting the actions of subsequent programs.

[0045] In a specific embodiment of the present invention, Figures 1A to 3As shown, the first opening of the packaging box 200 has a lower cover 201 opposed to the upper cover 2013, the upper cover 2013 and the top side of the packaging box 200 are connected at a third fold 209, a gap 2091 is provided in the middle of the third fold 209, and a latch 2018 is connected to the outer edge of the lower cover 2014 through a fourth fold 2016, and the latch 2018 fits the gap 2091 and can be inserted into the packaging box 200 from the gap 2091. The gap 2091 can be set on the third fold 209, or can be located at a position close to the third fold 209 on the edge of the top side, or can be located at a position close to the third fold 209 on the edge of the upper cover 2013, which will not be described in detail here, as long as the latch 2018 can be inserted and fixed into the gap 2091.

[0046] In order to push the latch 2018 of the lower cover 201 into the gap 2091, as shown in FIG. Fig. 9 As shown, the packaging box fastening mechanism 3 further includes a second flip cover folding mechanism 33. The packaging box transfer mechanism 4 transfers the packaging box 200 after the first flip cover folding mechanism 32 has folded the upper cover to the second flip cover folding mechanism 33.

[0047] The second flip cover folding mechanism 33 includes an auxiliary shaft 331, an auxiliary push plate 332, an outer push plate 333, a second folding mechanism 334 and a second folding platform 335 that clamps the packaging box 200 in a three-dimensional state; the auxiliary push plate 332 pushes the outer side of the upper cover 2013 that has been buckled under the drive of the second servo motor 335, and the front end of the auxiliary push plate 332 has two opposite lugs 3321, which are respectively pressed on the outer side of the upper cover 2013 and are located near the two ends of the gap 2091, and the gap 2091 will be split; the auxiliary shaft 331 is located on the outer side of the lower cover 201, and moves upward under the drive of the fourth driving mechanism, thereby driving the lower cover 201 to fold from bottom to top. Similarly, the fourth driving mechanism The outer push plate 333 is located at the front side of the first opening 201 and outside the lower cover 201. The outer push plate 333 pushes the outer side of the lower cover 2014 to flip the inner cover of the packaging box under the drive of the third driving mechanism 336. The third driving mechanism is preferably an electric cylinder, so that the outer push plate 333 can be stably adjusted to different positions according to the height of the packaging box 200. The second folding mechanism 334 is located at the upper part of the outer push plate 333, and is driven by the fifth driving mechanism to push and fold the tongue 2018 inward along the fourth fold 2016. The tongue 2018 is inserted into the cracked gap 2091. Preferably, the fifth driving mechanism is a cylinder, thereby driving the outer push plate 333 to move forward and backward stably. In this way, the lower cover 2014 can be inserted into the cracked gap. When a portion of the latch 2018 has been inserted into the cracked gap 2091 , the auxiliary push plate 332 with the lug 3321 can be withdrawn so that the outer push plate 333 continues to push the lower cover 201 to drive the latch 2018 to be fully inserted into the gap 2091 , thereby achieving the fastening of the lower cover 201 .

[0048] Preferably, in order to prevent the lower cover 2014 from failing to be truly fastened due to misoperation, a second suction cup structure 3331 can be provided on the outer surface of the outer push plate 333. After the latch 2018 is fastened, the suction cup structure of the outer push plate 333 is controlled by the air pump to adsorb the outer side surface of the lower cover 2014. The negative pressure value generated by the second suction cup structure 3331 sucking the lower cover 2014 will be fed back to the control unit. The control unit compares the set negative pressure value with the feedback negative pressure value to determine whether the lower cover 2014 is fastened. If the feedback negative pressure value is higher than the negative pressure value set by the control unit, it indicates that the lower cover 2014 is not fastened. The control unit will control the alarm unit to alarm or the display unit to display the current status, etc., thereby avoiding the lower cover 2014 not being fastened and affecting the actions of subsequent programs.

[0049] As described above, after the first opening of the packaging box 200 is completely closed, the packaging box transfer mechanism 4 transfers the packaging box to the product conveying mechanism 1, and the product conveying mechanism 1 loads the transported product into the packaging box 200 from the second opening 202 of the packaging box 200; subsequently, the packaging box transfer mechanism 4 transfers the packaging box to the packaging box fastening mechanism 3 again, and the packaging box fastening mechanism 3 seals the second opening 202 of the packaging box. In a specific embodiment of the present invention, the packaging box fastening mechanism 3 used to seal the first opening 201 and the second opening 202 can be the same mechanism, or another identical mechanism set oppositely, which will not be described in detail here.

[0050] In a specific embodiment of the present invention, it is preferred that sensors are provided on each platform, namely, the straightening platform 231, the fastening platform 311, and the folding platform.
