[0027] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0028] Now, with reference to the drawings, a preferred embodiment of the present utility model will be further described. In combination with Figure 1 and Figure 2 As shown, the automatic box folding device for packaging boxes includes a support frame 10. Along the support frame 10, a storage fixture 100, a folding edge mechanism 200, and a buckling edge mechanism 300 are sequentially arranged. The storage fixture 100 is used to store sheet-shaped box bodies. At the bottom of the storage fixture 100, a handling mechanism 400 is provided. The handling mechanism 400 is used to transport the sheet-shaped box bodies from the bottom of the storage fixture 100 to the folding edge mechanism 200. The folding edge mechanism 200 is used to bend the surrounding edges of the sheet-shaped box bodies upward to form a surrounding around the bottom of the box body. The buckling edge mechanism 300 is used to buckle the tongue edges on both sides of the box body that has already formed a surrounding into the inner side of the box body. Compared with the prior art, through the folding edge mechanism 200 and the buckling edge mechanism 300, the present utility model automatically completes all the operations of further surrounding the surrounding edges of the box body and buckling the tongue edges on the surrounding edges without manual intervention, greatly improving the production efficiency and saving labor costs at the same time.

[0029] Furthermore, on the basis of the above embodiments, as Figure 2As shown, the storage fixture 100 is arranged above the support frame 10 and includes a horizontally arranged bracket 110 and a plurality of limiting rods 120 vertically installed on the bracket 110. The limiting rods 120 limit the length and width of the box body of the sheet material to be compressed on a plane, enabling it to fall by gravity within the range surrounded by the limiting rods 120. Preferably, the connection between the limiting rods 120 and the bracket 110 is detachable, so that the mutual distance between the limiting rods 120 can be adjusted according to the size of different box bodies, thereby enabling this application to adapt to box bodies of different sizes.

[0030] Furthermore, on the basis of the above embodiments, as Figure 2 shown, the handling mechanism 400 includes a first propulsion cylinder 410 and a first guide rail 420, which are arranged in parallel along the direction of the support frame 10. A first sliding seat 430 is arranged on the first guide rail 420, and the first sliding seat 430 can slide along the first guide rail 420. A connecting seat 440 is arranged on the first sliding seat 430, and the connecting seat 440 is connected to the driving end of the first propulsion cylinder 410. When the first propulsion cylinder 410 is started, the connecting seat 440 can move along the first guide rail 420. An adsorption device 450 is arranged on the connecting seat 440, and the adsorption device 450 is used to adsorb the sheet-shaped box body from the bottom of the storage fixture 100.

[0031] Furthermore, on the basis of the above embodiments, as Figure 2 shown, the adsorption device 450 includes a first lifting cylinder 451 and a connecting frame 452. The first lifting cylinder 451 can drive the connecting frame 452 to move up and down. A plurality of suction cups 453 are arranged upward at the top of the connecting frame 452. When it is necessary to move the sheet-shaped box body from the bottom of the storage fixture 100 to the hemming mechanism 200, start the first propulsion cylinder 410 to drive the adsorption device 450 on the connecting seat 440 to move to the bottom of the storage fixture 100, then start the first lifting cylinder 451 to drive the suction cups 453 to rise until they contact the bottom of the sheet-shaped box body to adsorb it, and then start the first propulsion cylinder 410 to drive the adsorption device 450 on the connecting seat 440 to move to the hemming mechanism 200.

[0032] Furthermore, on the basis of the above embodiments, in combination with Figure 1 、 Figure 3 and Figure 4As shown, the hemming mechanism 200 includes a pressing device 210 disposed above the support frame 10, left and right edge gathering devices 220 disposed on both sides of the support frame 10, and front and rear edge gathering devices 230 disposed at the bottom of the support frame 10. When the sheet-shaped box body is placed on the support frame 10 below the pressing device 210 through the handling mechanism 400, first, the pressing device 210 is activated to press the bottom of the box body, and then the left and right edge gathering devices 220 and the front and rear edge gathering devices 230 are activated to bend the surrounding edges around the box body upward to form a gathering around the bottom of the box body.

[0033] Furthermore, on the basis of the above embodiment, in combination with Figure 1 、 Figure 3 and Figure 4 As shown, the pressing device 210 includes a second lifting cylinder 211 disposed at the top of the support frame 10 and a pressing fixture 212 disposed at the bottom of the second lifting cylinder 211. The shape and size of the bottom of the pressing fixture 212 are the same as those of the bottom of the box body. The second lifting cylinder 211 can drive the pressing fixture 212 to move up and down. The left and right edge gathering devices 220 include second pushing cylinders 221 disposed on the left and right sides of the support frame 10 and edge gathering blocks 222. The second pushing cylinders 221 can drive the edge gathering blocks 222 to move towards each other. The front and rear edge gathering devices 230 include a third lifting cylinder 231 disposed at the bottom of the support frame 10 and an edge gathering fixture 232 disposed at the top of the third lifting cylinder 231. When the sheet-shaped box body is placed on the support frame 10 below the pressing device 210 through the handling mechanism 400, the second lifting cylinder 211 drives the pressing fixture 212 to descend to press the bottom of the box body on the support frame 10. Then, the second pushing cylinders 221 can drive the edge gathering blocks 222 to move towards each other to bend the surrounding edges on the left and right sides of the box body upward. Finally, the third lifting cylinder 231 drives the edge gathering fixture 232 to move upward to bend the surrounding edges on the front and rear sides of the box body upward, thereby completing the gathering around the bottom of the box body.

[0034] Furthermore, on the basis of the above embodiment, in combination with Figure 1 、 Figure 3 and Figure 4 As shown, a plurality of suction cups 453 are provided in the middle of the edge gathering fixture 232. After the third lifting cylinder 231 drives the edge gathering fixture 232 to move upward to bend the surrounding edges on the front and rear sides of the box body upward, the gathered box body is adsorbed on the suction cups 453.

[0035] Furthermore, on the basis of the above embodiment, in combination with Figure 1 、 Figure 3 and Figure 4As shown, the third lifting cylinder 231 is also installed on the connecting seat 440, and the distance between it and the first lifting cylinder 451 is the same as the distance between the storage fixture 100 and the pressing device 210. In this way, after the hemming mechanism 200 forms an enclosure around the bottom of the box body, the first propulsion cylinder 410 is started continuously. The connecting seat 440 moves along the first guide rail 420. While moving the adsorption device 450 to the hemming mechanism 200, it also moves the already enclosed box body to the edge-locking mechanism 300. After the edge-locking is completed, the first propulsion cylinder 410 is started to retract. At this time, the hemming fixture 232 returns below the pressing fixture 212 to wait for hemming, and at the same time, the adsorption device 450 returns below the storage fixture 100 to wait for adsorbing the sheet-shaped box body. Repeating this way can further improve the efficiency.

[0036] Furthermore, on the basis of the above embodiments, in combination with Figure 1 、 Figure 3 and Figure 4 As shown, the edge-locking mechanism 300 includes L-shaped edge-locking members 310 and a rotating device 320 arranged on both sides of the support frame 10. The L-shaped edge-locking members 310 are axially connected to the rotating device 320. When the box body that has completed the enclosure moves to both sides of the L-shaped edge-locking members 310, the rotating device 320 drives the L-shaped edge-locking members 310 to rotate, so as to buckle the tongue edges on both sides of the box body into the inner side of the box body, and thus complete the entire box folding work.

[0037] Details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes within the meaning and scope of the equivalent elements of the claims in the present invention.
