4) In a state that the cover body 320 is fixedly clamped by the cover clamping mechanism 50, the flanging mechanism 60 contacts the folded plates 324 on two sides of the cover plate 321, and then flanging is performed to complete the bending of the folded plates 324;

5) The cover clamping mechanism 50 releases the cover body 320, the conveying mechanism 30 drives the packing box to move along the conveying direction, and the packing box is about to reach the position corresponding to the cover closing mechanism 10;

6) The conveying mechanism 30 continues to drive the packing box to move along the conveying direction, and the cover closing mechanism 10 applies force to the cover plate 321 so as to bend the cover plate 321 relative to the box body 310 and press down to be close to the box body 310;

7) The folded plate 324 gradually extends into the box cavity 311 along with the cover 320 gradually approaching the box body 310, and when the cover plate 321 covers the box body 310 and closes the box cavity 311, the folded plate 324 completely enters the box cavity 311;

8) The conveying mechanism 30 continues to operate to drive the packing box to leave the position corresponding to the cover closing mechanism 10 and then enter the position corresponding to the edge folding mechanism 20;

9) The conveyor 30 is again suspended and the flap unit applies a force to the flap 324 to bend the flap 324 relative to the end plate 322;

10 Under the state that the plate 323 keeps the plate 322 bending relative to the plate 322, the folding unit applies force to the plate 322 to drive the plate 322 to bend and rotate relative to the plate 321;

11 End plate 322 rotates with respect to cover plate 321 and gradually approaches one side wall of case 310, while insert plate 323 follows the rotation of end plate 322 to gradually approach case 310 and insert slot 312;

12 When the insertion plate 323 is fully inserted into the insertion slot 312, the packing box is completely covered, and the conveying mechanism 30 is started again to operate so as to drive the packing box to continue moving until the packing box is off line.

Referring to fig. 1, the conveying mechanism 30 includes a conveying line body 31 capable of driving the package boxes to move along a linear track, an object carrying plane for carrying the package boxes is arranged on the conveying line body 31, the object carrying plane is preferably a horizontal plane, and the conveying line body 31 preferably drives the package boxes to move horizontally and linearly along the linear track in the horizontal direction. The frame 40 includes a column 41 protruding in a vertical direction with respect to the carrier plane of the conveying line body 31, and further includes a first carrier 42, a second carrier 43, and a third carrier 44, where the first carrier 42 is suspended with respect to the conveying line body 31, and the conveying line body 31 extends below the first carrier 42, and both the second carrier 43 and the third carrier 44 are located at sides of the conveying line body 31 in a horizontal direction.

Referring to fig. 5 and 6, when the package is placed on the conveyor line 31, the front side of the package cover 321 faces away from the closing mechanism 10 and the hemming mechanism 20, and the front side of the cover 321 faces toward the bottom of the box 310 when the cover 321 is closed to the box 310. The capping mechanism 50 includes a clamping driving member 51 fixedly mounted on the first carrier 42, a front clamping arm 521 rotatably connected to the clamping driving member 51, and a rear clamping arm 522 rotatably connected to the clamping driving member 51, where the front clamping arm 521 and the rear clamping arm 522 are suspended from the conveying mechanism 30, and a clamping opening with an opening facing the conveying mechanism 30 is formed therebetween.

The clamp driving member 51 can drive the front clamp arm 521 and the rear clamp arm 522 to rotate simultaneously, thereby switching the open/close state of the clamp opening or adjusting the opening degree of the clamp opening.

Optionally, when the package is just fed to the conveying mechanism 30, the opening of the holding opening is maximized, the front clamping arm 521 extends reversely in the conveying direction, and the rear clamping arm 522 extends in the conveying direction, so that the package can smoothly reach the lower part of the capping mechanism 50. When the cover 320 reaches the position opposite to the holding opening, the clamping driving member 51 drives the front clamping arm 521 to rotate and gradually bring the front clamping arm 521 close to the front side of the cover 321, and simultaneously drives the rear clamping arm 522 to rotate and gradually bring the rear clamping arm 522 close to the rear side of the cover 321, and when the opening of the holding opening is minimum, the front clamping arm 521 and the rear clamping arm 522 are respectively abutted against the front side and the rear side of the cover 321, so that the flanging mechanism 60 applies force to the folded plates 324 on both sides of the cover 321. After the flanging mechanism 60 finishes bending the folded plate 324, the clamping driving piece 51 drives the front clamping arm 521 and the rear clamping arm 522 to leave the cover plate 321, and the opening degree of the clamping opening is readjusted to be maximum, so that the packaging box is released.

Specifically, referring to fig. 4 to 5, in some embodiments, the clamping driving member 51 is a clamping cylinder, including a clamping cylinder body 511 fixedly mounted on the first carrier 42, and further including an output rod 512 telescopically connected to the clamping cylinder body 511, where a track of telescopic movement of the output rod 512 relative to the clamping cylinder body 511 is directed to the conveying line body 31; the capping mechanism 50 further includes a front link 531 and a rear link 532, two ends of the front link 531 are respectively hinged to the output rod 512 and the front clamping arm 521, two ends of the rear link 532 are respectively hinged to the output rod 512 and the rear clamping arm 522, the front link 531 and the rear link 532 are respectively disposed on two sides of a straight line where a movement track of the output rod 512 is located, and the front clamping arm 521 and the rear clamping arm 522 are respectively disposed on two sides of the straight line where the movement track of the output rod 512 is located.

Still further, the capping mechanism 50 also includes a common pivot 54, a front pivot 541, and a rear pivot 542. The common pivot 54 rotatably penetrates through the output rod 512, one end of the front connecting rod 531, which is relatively far away from the front clamping arm 521, is hinged to the common pivot 54, and one end of the rear connecting rod 532, which is relatively far away from the rear clamping arm 522, is hinged to the common pivot 54; the front clamping arms 521 are arranged in pairs, the front pivot 541 is connected to the second carrier 43 and penetrates through the two front clamping arms 521, the rear clamping arms 522 are arranged in pairs, and the rear pivot 542 is connected to the second carrier 43 and penetrates through the two rear clamping arms 522. Accordingly, the front clamp arm 521 is indirectly hinged to the frame 40 via a front pivot 541 and is indirectly rotatably coupled to the output rod 512 via a front link 531, and the rear clamp arm 522 is indirectly hinged to the frame 40 via a rear pivot 542 and is indirectly rotatably coupled to the output rod 512 via a rear link 532.

Alternatively, the linear path of movement of the output rod 512 relative to the first carriage 42 is perpendicular to the load plane of the transfer wire body 31 and will always bisect the angle between the front 521 and rear 522 clamp arms.

The flanging mechanisms 60 are provided in pairs on both sides of the conveying mechanism 30 in the horizontal direction, and bend the folded plates 324 located on both sides of the cover 321, respectively. The flanging mechanism 60 comprises a flanging part 61 rotatably installed relative to the frame 40, and further comprises a flanging driving piece 62 installed on the frame 40, wherein the flanging driving piece 62 is connected with the flanging part 61 in a driving manner, and can push the flanging part 61 to rotate relative to the frame 40 so as to drive a folded plate 324 contacting the flanging part 61 to bend and rotate relative to the cover plate 321. The flanging part 61 drives the folded plate 324 to bend at least 90 degrees relative to the cover plate 321, then maintains the current position for a period of time, and continuously abuts against the folded plate 324 to prevent the folded plate 324 from rebounding and resetting. Then the conveying mechanism 30 is restarted, the cover closing mechanism 10 starts to apply force to the cover plate 321 to drive the cover plate 321 to press and bend, and the flanging part 61 continues to abut against the folded plate 324 for a period of time until a part of the folded plate 324 enters the box cavity 311.

Referring to fig. 5 and 6, the automatic packing box closing device 100 further includes a plurality of pivot seats 214, wherein a portion of the pivot seats 214 are fixedly mounted on the third carrier 44, and the turn-up driving member 62 includes a turn-up driving cylinder 621 rotatably mounted on the third carrier 44, a turn-up driving shaft 622 connected to a power output end of the turn-up driving cylinder 621, and a turn-up driving seat 623 fixedly connected to the turn-up driving shaft 622 and fixedly connected to the turn-up portion 213. The flanging driving shaft 622 is rotatably installed in the pivot seat 214, and as the flanging driving cylinder 621 deforms in a telescopic manner, the flanging driving cylinder 621 drives the flanging driving shaft 622 to rotate through the power output end thereof, and the flanging driving seat 623 rotates along with the rotation of the flanging driving shaft 622 and drives the flanging portion 213 to rotate.

Alternatively, the folding portion 213 contacts the flap 324 at a side of the cover 320 facing the cover closing mechanism 10 and the folding mechanism 20 and pushes the flap 324 to fold and rotate. The turning part 213 drives the folded plate 324 to bend and rotate by an angle larger than 90 degrees, so that the connection part of the folded plate 324 and the cover plate 321 is ensured to be fully deformed, and the resilience and resetting capability of the folded plate 324 relative to the cover plate 321 are inhibited.

It should be noted that in some embodiments, the automatic package closing apparatus 100 operates without the flap 324, so the flanging mechanism 60 can be omitted, and as mentioned above, the flap 324 is not an essential structure in the package; in addition, the capping mechanism 50 may be set or set removed according to actual needs. For example, when the product or the goods loaded in the package is heavy and the package can be pressed against the conveyor line body 31, the capping mechanism 50 may be omitted and only the turnup mechanism 60 may be provided, and the turnup mechanism 60 applies a pushing force to the flap 324 so as not to cause the package to deviate from the conveyor mechanism 30; when the material of the package has high rigidity and the cover 321 and the folded plate 324 have been pre-folded, the flanging mechanism 60 can bend the folded plate 324 more easily.

In the utility model, the cover closing mechanism 10 comprises a cover closing member 11 suspended above the conveying mechanism 30, the flanging mechanism 20 comprises a cover closing member 21 suspended above the conveying mechanism 30, and passages for the packing boxes to move through are arranged between the cover closing member 11 and the conveying line body 31 and between the cover closing member 21 and the conveying line body 31. The cover 11 and the cover 21 are arranged in sequence in the conveying direction, i.e. the packages on the conveyor line body 31 pass under the cover 11 first and then under the cover 21 during movement in the conveying direction. The closing cap 11 is formed with a lead-in end 1114 at the end closest to the conveying mechanism 30, and the lead-in end 1114 extends obliquely toward the closing cap 21, and the lead-in end 1114 closest to the conveying mechanism 30 means: the lead-in 1114 is closest to the load plane of the transfer wire body 31 among the various locations in the closure 11.

Further, the end of the cover 11 furthest from the conveyor mechanism 30 forms a start end 1113. Referring to fig. 5 and 7, the cover closing mechanism 10 includes a rod frame support member 12 fixedly disposed relative to the frame 40, the cover closing member 11 includes a bent extension rod frame 111 fixedly connected to the rod frame support member 12, and the bent extension rod frame 111 is suspended relative to the conveying mechanism 30 and is inclined relative to the conveying mechanism 30 in the following direction: the angle between the side of the bent extension rod frame 111, which is relatively close to the conveying mechanism 30, and the conveying line body 31 is provided with an opening which is far away from the flanging mechanism 20, and a channel for the packaging box to pass through is formed between the conveying line body 31 and the bent extension rod frame 111. Both ends of the bent extension rod frame 111 form a start end 1113 and an introduction end 1114, respectively.

The start end 1113 and the lead-in end 1114 are positioned one after the other in the conveying direction, and the packages first reach under the start end 1113 and then reach under the lead-in end 1114 as they move past under the lid 11. The bent extension rod frame 111 is projected onto the conveying line body 31, the initial end 1113 forms a head end projection on the conveying line body 31, the lead-in end 1114 forms a tail end projection on the conveying line body 31, and the head end projection and the tail end projection are sequentially arranged along the conveying direction.

In particular, the bar support 12 is a U-shaped bracket that opens toward the delivery mechanism 30. The curved extension rod frame 111 comprises an arc rod section 1111 and a straight rod section 1112 which are connected into a whole, the straight rod section 1112 is fixedly connected to the U-shaped bracket and is parallel to the supporting plane of the conveying line body 31, and the distance from the supporting plane of the conveying line body 31 to the straight rod section 1112 is matched with the height of the box body 310 of the packing box; the circular arc rod section 1111 is connected to an end of the straight rod section 1112 relatively far from the hemming mechanism 20, an end of the circular arc rod section 1111 relatively far from the straight rod section 1112 forms a start end 1113, and an end of the straight rod section 1112 relatively far from the circular arc rod section 1111 forms an introduction end 1114. The curvature center of the curved extension rod frame 111, that is, the curvature center of the circular arc rod section 1111 is located above the straight line rod section 1112, and on one side of the circular arc rod section 1111 relatively far away from the conveying line body 31, the shape of the circular arc rod section 1111 makes the included angle between one side of the circular arc rod section 1111 relatively near to the conveying line body 31 and the conveying line body 31 be in a decreasing trend along the conveying direction.

After the folded plate 324 is bent relative to the cover plate 321 through the flanging mechanism 60, the clamping driving piece 51 controls the clamping opening to be opened so as to release the cover body 320, the conveying mechanism 30 restarts to drive the packing box to move, the overturning part 213 continues to keep the abutting action on the folded plate 324, the folded plate 324 slides along with the overturning part 213 along with the movement of the packing box, and the bending angle of the folded plate 324 relative to the cover plate 321 is kept unchanged. The abutting of the folding portion 213 against the flap 324 continues until the start end 1113 applies a pushing force to the rear side of the cover 321, so that the flap 324 follows the bending of the cover 321 to enter the box cavity 311, and the flanging mechanism 60 is disengaged from the flap 324 after the flap 324 enters the box cavity 311. The portion of the bent extension rod holder 111 contacting the cover plate 321 is then gradually moved away from the start end 1113 and gradually approaches the lead-in end 1114 along the bent extension rod holder 111, and in the process, the cover plate 321 is pressed and bent by the circular arc rod section 1111 and the linear rod section 1112 in sequence and gradually approaches the case 310.

Alternatively, the linear rod section 1112 extends linearly in the conveying direction and is adjacent to the capping member 21 to form the lead-in end 1114 directed toward the capping member 21.

Alternatively, a line extending outwardly from the start end 1113 in a direction away from the curved extension bar frame 111 and tangential to the circular arc bar segment 1111 is perpendicular to the conveying direction and perpendicular to the horizontal direction.

Optionally, the linear rod section 1112 and the circular arc rod section 1111 are integrally formed, the linear rod section 1112 is connected to the other end of the circular arc rod section 1111 relatively far from the start end 1113, and the distance from the other end of the circular arc rod section 1111 relatively far from the start end 1113 to the conveying line body 31 is equal to the distance from the linear rod section 1112 to the conveying line body 31.

Alternatively, the cover 11 may be removably and fixedly attached to the pole support 12, and in the embodiment of FIG. 7, the linear pole segment 1112 is removably and fixedly attached to the pole support 12.

It will be appreciated that in other embodiments, the straight bar section 1112 may be omitted, in which case the entire curved extension bar 111 is the circular arc bar section 1111, and in which case the circular arc bar section 1111 forms the lead-in 1114 of the closure 11 relatively close to the conveying mechanism 30 and relatively close to the end of the hemming mechanism 20.

In the embodiment where the straight line bar section 1112 and the curved extension bar frame 111 are both arc bar sections 1111, the arc bar sections 1111 form the leading end 1114 relatively close to the ends of the conveying mechanism 30 and the hemming mechanism 20, and a straight line extending outward from the leading end 1114 in a direction away from the arc bar sections 1111 and tangential to the arc in which the arc bar sections 1111 are located extends in the conveying direction.

Optionally, the conveying mechanism 30 further includes a limiting blocking portion 32, referring to fig. 1, where the limiting blocking portion 32 is fixedly protruding from a supporting plane of the conveying line body 31, and can abut against the box body 310 to limit and restrict the packing box, so as to prevent the packing box from being subjected to the thrust action of the cover closing member 11 and moving in the reverse direction of the conveying direction. The pressure of the cover 11 acting on the cover 320 can be used to bend the cover 321 relative to the case 310 and gradually approach the case 310 by the limiting stopper 32 abutting against the case 310. It can be appreciated that in other embodiments, the limiting blocking portion 32 may be omitted, and a limiting groove may be formed on the conveying line body 31, and the box body 310 may be fixed by being limited by the wall of the limiting groove after being placed in the limiting groove.

Referring to fig. 7, the capping member 21 includes a capping portion 211 suspended above the conveying mechanism 30, a folding portion 212 rotatably connected to an end of the capping portion 211 relatively close to the capping mechanism 10, and a separately provided turning portion 213. The folding portion 212 belongs to a component of the aforementioned folding unit, the folding portion 213 belongs to a component of the aforementioned folding unit, the folding portions 213 are arranged in pairs, and the two folding portions 213 are respectively rotatably disposed at two ends of the folding portion 212 in the width direction of the conveying line body 31, and the width direction of the conveying line body 31 is a horizontal direction perpendicular to the conveying direction. The cover portion 211 is a plate-shaped structure parallel to the supporting plane of the conveying line body 31, and is used for further applying pressure to the cover plate 321 to consolidate the covering effect of the cover plate 321 on the box body 310, a gap channel for the packaging box to pass through is formed between the cover portion 211 and the conveying line body 31, and a gap inlet of the gap channel is formed between one end of the cover portion 211 relatively close to the cover closing mechanism 10 and the conveying line body 31. The fold 212 can rotate relative to the gland 211 to open or close the gap entrance.

When the hinge 212 is rotated to open the gap entrance, the gap passage is opened, which allows the package to enter and pass therethrough. When the package reaches the position below the cover pressing portion 211, the conveying mechanism 30 pauses again, the flanging mechanism 20 firstly controls the turning portion 213 to rotate relative to the folding portion 212, the pressing force of the turning portion 213 acts on the inserting plate 323 to enable the inserting plate 323 to bend relative to the end plate 322 until the inserting plate 323 rotates to be aligned with the inserting slot 312 of the box body 310, and then the turning portion 213 is static and continuously contacts the inserting plate 323; after the turning portion 213 stops rotating, the flanging mechanism 20 controls the turning portion 212 to rotate relative to the capping portion 211 and close the gap entrance, in this process, the pressure of the turning portion 212 acts on the end plate 322 of the cover 320 and bends the end plate 322, so that the end plate 322 bends relative to the cover 321 and covers one side of the box 310, and meanwhile, the insert plate 323 gradually inserts into the slot 312 along with the bending rotation of the end plate 322.

In some embodiments, the distance from the conveying mechanism 30 to the lead-in end 1114 is greater than or equal to the distance from the conveying mechanism 30 to the capping portion 211, and referring to fig. 7, specifically, the distance from the conveying mechanism 30 to the lead-in end 1114 is equal to the distance from the linear rod section 1112 to the lead-in end 1114, the distance from the conveying mechanism 30 to the capping portion 211 is equal to the distance from the lead-in end 1114 to the load-carrying plane of the conveying line body 31, the distance is the height dimension of the clearance channel, and the height dimension of the clearance channel is equal to the height dimension of the packing box in the capping state. The following classification discusses the meaning of the relationship of the distance of the conveying mechanism 30 to the lead-in 1114 and the distance of the conveying mechanism 30 to the capping portion 211.

In the case where the distance from the conveying mechanism 30 to the lead-in end 1114=the conveying mechanism 30 to the capping portion 211, from when the pressure is applied to the cover plate 321 entirely by the lead-in end 1114, to when the pressure is applied to both the lead-in end 1114 and the capping portion 211 simultaneously to the cover plate 321, and to when the cover plate 321 is separated from the lid 11 and is acted on by the capping portion 211 entirely, the position state of the cover plate 321 with respect to the case 310 is unchanged all the time, and the cover plate 321 always covers the case 310 and always closes the case cavity 311.

In the case where the distance from the feeding mechanism 30 to the lead-in end 1114 is greater than the distance from the feeding mechanism 30 to the capping portion 211, from the time when the pressure is applied to the cover plate 321 entirely by the lid 11, to the time when the pressure is applied to the cover plate 321 by both the lead-in end 1114 and the capping portion 211, the cover plate 321 is always rotated to be gradually brought close to the case 310, from the time when the pressure is applied to the cover plate 321 by both the lead-in end 1114 and the capping portion 211, to the time when the cover plate 321 is separated from the lid 11 and the pressure is applied entirely by the lid 21, the cover plate 321 is further pressed down, and the cover plate 321 is further rotated to be folded with respect to the case 310 until the cover plate 321 is completely covered on the case 310.

It can be seen that the cover 321 is not rebounded and reset to rotate relative to the case 310 under the pressure constraint of the lid 11 and the lid 21 during the transfer of the package from under the lid 11 to under the lid 21 until the package is completely under the lid 21. This is of great importance for closing the aircraft box 300 with the flap 324 of the cover 320: if the package is transferred from under the lid 11 to under the cover 21, the flap 324 extending into the cavity 311 is likely to be separated from the cavity 311, and if the flap 324 is separated from the cavity 311, the cover 21 applies pressure to the cover 321 again to bend the cover 321 back toward the box 310, so that the flap 324 is easily exposed to the box 310, which may result in incorrect closing of the aircraft box 300.
