The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0037] As attached Figure 2 , Attachment Figure 3The triangular packing box sealing mechanism of the present invention is shown, comprising a frame 8, on which a box feeding conveyor line 9 for conveying cartons 7 is installed, and synchronous belt conveyor lines 10 are installed on both sides of the box feeding conveyor line 9. Push plates 101 for pushing the cartons 7 forward are connected at intervals on the synchronous belts of the synchronous belt conveyor line 10 to prevent the carton 7 from stopping when being folded and pressed, so that the box sealing process can be carried out neatly and orderly.

[0038] As attached Figure 1 As shown, the carton 7 includes a square bottom plate, a first side plate 71 perpendicular to the bottom plate is provided at the long side of the bottom plate, a second side plate 72 perpendicular to the bottom plate and connected to the first side plate 71 is provided at the short side of the bottom plate, the height of the second side plate 72 is less than the height of the first side plate 71, the upper edge of the first side plate 71 has a side fold 73 extending upward, the width of the side fold 73 is less than the width of the second side plate 72, leaving a gap for subsequent folding, and a strip groove 74 is provided at the connection between the side fold 73 and the second side plate 72. When sealing the carton, the carton 7 enters the box feeding conveyor line 9 along the direction of the long side.

[0039] A first folding mechanism 1 , a second folding mechanism 2 , a third folding mechanism 3 , a fourth folding mechanism 4 and a fifth folding mechanism 5 are sequentially installed along the conveying direction of the box-in conveying line 9 .

[0040] As attached Figure 4 As shown, the first folding mechanism 1 includes a first cylinder 11, and a first pressing block 111 is installed at the output end of the first cylinder 11. The bottom surface of the first pressing block 111 is a horizontal surface. The first cylinder 11 is used to fold the side fold 73 on the rear side of the carton 7 toward the inside of the carton 7. A guide plate 12 located above the second side plate 72 is installed between the first folding mechanism 1 and the second folding mechanism 2. When the carton 7 passes through the guide plate 12, the side fold 73 on the front side is blocked and folded backward, while the side fold 73 on the rear side is restricted by the guide plate 12 to maintain a folded state. The strip groove 74 is folded to form a slot 75, and the carton 7 becomes attached. Figure 1 The a form in .

[0041] The second folding mechanism 2 includes a second cylinder 21 installed on both sides of the length direction of the carton 7 and a side push cylinder 22 installed on both sides of the width direction of the carton 7. The second cylinder 21 is installed obliquely above the carton 7. A second pressing block 211 is installed at the output end of the second cylinder 21. The bottom surface of the second pressing block 211 is an inclined surface, which is used to push the second side plates 72 on both sides of the carton 7 so that the upper part is folded inward into a slope shape, so that the carton becomes attached. Figure 1 In the b form, the side push cylinder 22 is used to fold the upper part of the first side plate 71 inward to form an upper folding plate 711, so that the carton becomes an attached Figure 1 The c form in .

[0042] The third folding mechanism 3 and the fifth folding mechanism 5 are connected with side limiters 32 located on both sides of the width direction of the carton 7. The side limiters 32 are used to keep the upper folding plate 711 in a folded state to prevent the upper folding plate 711 from rebounding after being folded.

[0043] As attached Figure 5 As shown, the third folding mechanism 3 includes two third cylinders 31 installed above the carton 7. The third cylinders 31 are pushed out inwardly and are used to fold the upper part of the upper folding plate 711 inwardly to form an upper folding leaf 712, so that the carton 7 becomes an attached Figure 1 The third folding mechanism 3 also includes a forming member 33 located between the upper folding plates 711, and both sides of the forming member 33 are inclined surfaces. When the third cylinder 31 is pushed out, the upper folding leaf 712 fits with the inclined surface of the forming member 33, making the folding and forming more reliable.

[0044] As attached Figure 6 As shown, the fourth folding mechanism 4 includes a fourth cylinder 41 installed above the carton 7, and the fourth cylinder 41 is used to fold the top of the upper hinge 712 downward to form an upper folding edge 713. The output end of the fourth cylinder 41 is installed with a folding member 42, which includes a horizontal pressing plate 421 and a vertical plate 422 located at the center of the pressing plate 421 and inserted between the upper hinges 712 on both sides, so that the carton 7 becomes an attached Figure 1 The e form in .

[0045] An upper limit member 43 is installed between the fourth folding mechanism 4 and the fifth folding mechanism 5 , and the upper limit member 43 is used to keep the upper hinge 712 in an inclined state after being folded.

[0046] As attached Figure 7 As shown, the fifth folding mechanism 5 includes a pressure guide 51 installed above the carton 7. The pressure guide 51 is located in the middle of the box feeding conveyor line 9. When the carton 7 passes through the fifth folding mechanism 5, the pressure guide 51 passes between the upper folding edges 713 on both sides, so that the upper folding edges 713 are inserted downward into the slot 75, and the carton 7 becomes attached. Figure 1 The f form in the Fig. 9 As shown, the pressure guide 51 is a strip-shaped body installed along the conveying direction. The strip-shaped body includes two side surfaces that gradually converge downward into a line. A gradually converging guide surface 511 is formed at the end of the strip-shaped body opposite to the conveying direction, so that the pressure guide 51 can be more smoothly inserted between the two upper folded edges 713 when the carton 7 advances along the box feeding conveyor line 9, so that the upper folded edge 713 is bent downward under the guidance of the outer shape of the pressure guide 51.

[0047] As attached Figure 8As shown, a sixth folding mechanism 6 is installed after the fifth folding mechanism 5, and a pressure guide 51 extends to the sixth folding mechanism 6. Top stoppers 61 are installed on both sides of the pressure guide 51 located at the sixth folding mechanism 6. The entrance of the top stopper 61 expands outward to facilitate the entry of the carton 7. Under the height limit of the top stopper 61, the upper folding leaf 712 is pressed downward to insert the upper folding edge 713 into the slot 75, and the upper folding leaf 712 is kept in a horizontal state, so that the carton 7 becomes attached. Figure 1 The g shape in the middle keeps the whole thing flat and solid to complete the box sealing.

[0048] The third folding mechanism 3, the fourth folding mechanism 4 and the fifth folding mechanism 5 all include a support frame 20 connected to both sides of the frame 8, as shown in the attached Figure 5 As shown, a mounting member 30 is mounted on the support frame 20, and the side limiting member 32 is sequentially connected to the mounting members 30 of the third folding mechanism 3, the fourth folding mechanism 4 and the fifth folding mechanism 5. The side limiting member 32 includes an upper limiting strip 321 and a lower limiting strip 322 in the shape of a long strip, and the distance between the upper limiting strips 321 on both sides is smaller than the distance between the lower limiting strips 322, so that the upper folding plate 711 maintains a corresponding inclination.

[0049] A transition bracket 50 is installed between the second folding mechanism 2 and the third folding mechanism 3. The upper limit bar 321 and the lower limit bar 322 extend to the transition bracket 50 to further stabilize the shape of the upper folding plate 711 before subsequent folding and pressing to avoid deformation caused by subsequent folding and pressing. The entrances of the upper limit bar 321 and the lower limit bar 322 expand outwards to facilitate the entry of the carton 7.

[0050] As attached Figure 7 As shown, a fixing member 40 is installed on the support frame 20, and the mounting member 30 is connected to the fixing member 40. The fixing member 40 is processed with a center hole and adjustment holes 401 located on both sides of the center hole. The mounting member 30 is processed with a mounting hole 301 and an arc hole 302 surrounding the mounting hole 301. The distance between the center hole and the adjustment hole 401 is the same as the distance between the mounting hole 301 and the arc hole 302, so that the mounting member 30 can rotate around the fixing member 40. The center hole and the mounting hole 301, the adjustment hole 401 and the arc hole 302 are connected by fasteners respectively. The mounting member 30 can be rotated and adjusted according to the inclination requirements of the upper folding plate 711, which is convenient to adjust and reduces the requirements for processing accuracy. In addition to the connection between the upper limit bar 321 and the lower limit bar 322, the connection structure of the mounting member 30 and the fixing member 40 can also be used in other structures, making the installation adjustment more flexible, more adaptable, and more versatile.
