DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure.

[0039] Two first edge clamping assemblies are symmetrically arranged above and below the first conveyor 100, a side trimming assembly is arranged in the middle of the first conveyor 100, a second edge clamping assembly is arranged on the connecting plate 103, and a flipping assembly is arranged in the connecting plate 103. When the stopper 102 moves to the first edge clamping assembly, it drives the first edge clamping assembly to move synchronously with the packaging box and perform edge clamping on the upper and lower sides of the packaging box. When the packaging box moves to the side trimming assembly, it triggers the edge trimming assembly to perform inward edge trimming on the two side edges of the packaging box. When the packaging box moves to the second edge clamping assembly, the stopper 102 drives the second edge clamping assembly to perform edge trimming on the two side edges of the packaging box, and then the flipping assembly drives the packaging box to flip.

[0040] The present invention sets a stopper 102 which moves synchronously with the packaging box. When the packaging box moves to the first edge pressing component, the stopper 102 drives the first edge pressing component to passively move synchronously with the packaging box and perform edge pressing on the upper and lower sides of the packaging box. When the packaging box moves to the edge closing component, the edge closing component is triggered to close the two side edges of the packaging box inward. When the packaging box moves to the second edge pressing component, the stopper 102 drives the second edge pressing component to press the two side edges of the packaging box, and then the flipping component drives the packaging box to flip. When the packaging box is transported, there is no need for manual edge sealing operation on the bottom of the packaging box, but the bottom of the packaging box is automatically and passively sealed and flipped to the opening facing upward.

[0041] Furthermore, a plurality of stoppers 102 are provided according to the length of the first conveyor 100 , and are arranged in an array and at equal intervals on the first conveyor 100 .

[0042] Furthermore, the position of the stop block 102 is close to the side edge of the packaging box, and the stop block 102 is connected to the conveyor belt in the first conveyor 100. The shape of the first positioning groove 101 is consistent with the conveyor belt, so that after the edge pressing is completed, the stop block 102 continues to move along with the other side of the conveyor belt until it returns to the initial position to continue the next edge pressing.

[0043] In an embodiment further provided by the present invention, the first edge clamping assembly includes a fixed bar 201 fixedly connected to the upper surface of the first conveyor 100, and one end of the fixed bar 201 is fixedly connected to the glue box 200, and the lower surface of the glue box 200 is connected to a limiting plate 202, and a limiting groove 203 is provided on one side surface of the limiting plate 202, and a moving wheel 204 is slidably connected in the limiting groove 203, and one end of the moving wheel 204 is connected to a glue delivery strip 206, and a first tension spring 205 is connected between the glue delivery strip 206 and the limiting plate 202, and one side of the glue delivery strip 206 is fixedly connected to a connecting bar 211, and one end of the connecting bar 211 is connected to a telescopic tube 212.

[0044] In an embodiment further provided by the present invention, the first pressing assembly also includes a second connecting bar 209 fixedly connected to the lower end of the glue feeding strip 206, and the lower end of the second connecting bar 209 is rotatably connected to the second pressing wheel 210, and one side of the second connecting bar 209 is rotatably connected to the first connecting bar 207, and one end of the first connecting bar 207 is rotatably connected to the first pressing wheel 208.

[0045] Furthermore, sealing glue is stored in the glue box 200, a hose for conveying glue is connected between the glue box 200 and the glue delivery strip 206, and a hole is provided at the connection between the glue delivery strip 206 and the second connecting strip 209 for circulating glue.

[0046] Furthermore, the limiting groove 203 is a right-angled triangular groove structure, the initial position of the moving wheel 204 is located in the hypotenuse of the limiting groove 203, and the lower end of the telescopic tube 212 abuts against the upper surface of the first conveyor 100.

[0047] Specifically, when the packaging box is being transported, the stopper 102 moves synchronously with the packaging box. When it reaches the telescopic tube 212, it drives the telescopic tube 212 to move forward. The telescopic tube 212 drives the glue delivery strip 206 to move, so that the moving wheel 204 slides downward and obliquely in the oblique edge of the limiting groove 203, so that the second pressing wheel 210 abuts against the upper and lower sides of the packaging box and rolls along the packaging box, pressing the upper and lower sides of the packaging box to make it folded. After folding, the moving wheel 204 moves to the straight edge of the limiting groove 203, and is pulled upward by the action of the first tension spring 205, thereby leaving the surface of the packaging box to complete the pressing, and causing the stopper 102 to disengage from the telescopic tube 212, and finally reset to the origin along the horizontal edge of the limiting groove 203 to wait for the next pressing.

[0048] In an embodiment further provided by the present invention, a through hole is provided on the surface of the second pressing wheel 210, a glue outlet pipe 302 is connected in the through hole, a glue outlet hole 303 is provided on the upper surface of the glue outlet pipe 302, a contact 300 is slidably connected in the glue outlet hole 303, a sealing plate 301 is connected at the lower end of the contact 300, the sealing plate 301 is located inside the glue outlet pipe 302 and abuts against below the glue outlet hole 303, a first spring 304 is connected between the lower end of the sealing plate 301 and the inside of the second pressing wheel 210.

[0049] Specifically, when the edge is pressed, the contact 300 contacts the packaging box, so that the contact 300 moves inward, and the sealing plate 301 no longer contacts the glue outlet hole 303, so that the glue in the glue outlet tube 302 flows out and is smeared on the surface of the packaging box.

[0050] Furthermore, when the glue liquid at the front flows out, the first pressing wheel 208 above it then rolls and presses the glue, so that the glue liquid is evenly distributed and the packaging box is further pressed and closed.

[0052] Furthermore, the shrink block 403 is a truncated cone block structure.

[0053] Specifically, when the shrink block 403 contacts the two sides of the packaging box during edge pressing, it is squeezed by the packaging box and slides inward along the shrink slope 402, so that the shrink block 403 no longer blocks the glue coating groove 401, thereby allowing the glue in the glue coating groove 401 to flow out and be smeared on the two sides of the packaging box.

[0054] In an embodiment further provided by the present invention, the edge trimming assembly includes a first connecting seat 504 and a second connecting seat 506 fixedly connected to the upper surface of the first conveyor 100, and the upper end of the first connecting seat 504 is rotatably connected to a connecting rod 503, and a second tension spring 505 is connected between the connecting rod 503 and the second connecting seat 506, and one end of the connecting rod 503 is rotatably connected to an edge trimming strip 500, and an edge trimming groove 501 is provided on one side surface of the edge trimming strip 500, and a friction strip 502 is rotatably connected in the edge trimming groove 501.

[0055] Furthermore, a small spring with relatively low elasticity is provided on the surface of the edge trimming groove 501. After the friction strip 502 is squeezed into the edge trimming groove 501, the small spring is compressed, and after the edge trimming is completed, the friction strip 502 is ejected and restored to its initial position.

[0056] Specifically, after the upper and lower sides of the packaging box are pressed, the packaging box is transported to the friction strip 502, and the two side edges of the packaging box opening are abutted against the friction strip 502. Under the friction force of the friction strip 502, the friction strip 502 is squeezed, and the edge strip 500 is driven to push the connecting rod 503 to rotate. Due to the inclined placement of the connecting rod 503, the side edges of the packaging box will be squeezed synchronously, causing it to retract inward, and under the initial bonding of the glue, it will form an inward-retracted state and no longer remain vertical.

[0057] In an embodiment further provided by the present invention, the second edge clamping assembly includes a second positioning groove 104 and a connecting tube 706 arranged on the upper surface of the connecting plate 103, and a moving part 701 is slidably connected in the second positioning groove 104, and the upper end of the moving part 701 is rotatably connected to a transmission bar 700, and the upper surface of the transmission bar 700 is rotatably connected to a driving bar 702, and one end of the driving bar 702 is rotatably connected to a driving block 703, and one end of the driving block 703 is fixedly connected to a driving plate 704, and a third tension spring 705 is connected between the connecting tube 706 and the transmission bar 700.

[0058] In an embodiment further provided by the present invention, the second edge clamping assembly also includes a vertical rod 801 rotatably connected to the upper surface of the connecting plate 103, and the surface of the vertical rod 801 is rotatably connected to a first transmission bar 802, and one end of the first transmission bar 802 is rotatably connected to a second transmission bar 803, and one end of the second transmission bar 803 is rotatably connected to a third transmission bar 804, and one end of the third transmission bar 804 is rotatably connected to the edge clamping plate 800, and the middle part of the third transmission bar 804 is rotatably connected to a cross bar 805, and the cross bar 805 is fixedly connected to the driving plate 704.

[0059] Furthermore, one end of the transmission bar 700 is located directly above the first positioning groove 101 .

[0060] Furthermore, after the trimming is completed, the packaging box and the stop block 102 move together to the end of the first conveyor 100. At this time, the two side edges of the packaging box are abutted against the edge holding plate 800, and the stop block 102 moves until it abuts against the transmission bar 700, thereby pushing the transmission bar 700 to move, thereby driving the drive bar 702 to move, and under the action of the moving part 701 and the second positioning groove 104, the movement direction of the drive bar 702 is fixed, thereby driving the drive bar 702 to horizontally push the drive plate 704.

[0061] Specifically, when the driving plate 704 moves horizontally, it drives the horizontal bar 805 to move horizontally, thereby driving the first transmission bar 802, the second transmission bar 803 and the third transmission bar 804 to unfold, so that the edge pressing plate 800 moves horizontally to the front end, thereby pressing the two side edges of the packaging box inward to complete the edge pressing.

[0062] Furthermore, after the stopper 102 leaves, under the action of the third tension spring 705, the edge pressure plate 800 and the transmission bar 700 return to their original positions.

[0063] In an embodiment further provided by the present invention, the flipping assembly includes a transmission rod 600 rotatably connected to the output end of the first conveyor 100, and the lower end of the transmission rod 600 is rotatably connected to the first bevel gear 601, and the first bevel gear 601 is meshed with the second bevel gear 602, and one end of the second bevel gear 602 is connected to a transmission tube 603, and one end of the transmission tube 603 is connected to the third bevel gear 605, and the third bevel gear 605 is meshed with a fourth bevel gear 606, and a bearing seat 604 is provided on the surface of the transmission tube 603, and the upper surface of the bearing seat 604 is fixedly connected to the lower surface of the connecting plate 103, and the fourth bevel gear 606 is penetrated and connected with a steering rod 607, and one end of the steering rod 607 is rotatably connected to the surface of one side of the connecting plate 103, and the other end of the steering rod 607 is connected to a steering seat 608, and one end of the steering seat 608 is rotatably connected to the surface of one side of another connecting plate 103, and a plurality of steering plates 609 are provided on the side surface of the steering seat 608.

[0064] Furthermore, after limited experiments, the gear ratios between the bevel gears are just satisfied, and when the packaging box moves onto the steering plate 609, the steering seat 608 rotates.

[0065] Specifically, when the first conveyor 100 is moving, it drives the first bevel gear 601 to rotate, thereby driving the second bevel gear 602 and the third bevel gear 605 to rotate, and then driving the fourth bevel gear 606 to rotate, so that the steering seat 608 rotates.

[0066] In an embodiment further provided by the present invention, one end of the connecting plate 103 is fixedly connected to a second conveyor 105, an edge banding machine 106 is provided at the lower middle part of the second conveyor 105, and a plurality of support seats 107 are fixedly connected to the lower surface of the first conveyor 100 and the lower surface of the second conveyor 105 respectively.

[0067] In the present invention, the staff first places the packaging box between the two first conveyors 100, and makes the bottom of the packaging box face forward. When the packaging box is transported, the block 102 moves synchronously with the packaging box, and first, it will be transported to the telescopic tube 212, where the block 102 will drive the telescopic tube 212 to move forward, and the telescopic tube 212 drives the glue delivery strip 206 to move, so that the moving wheel 204 slides downward in the inclined edge of the limit groove 203, so that the second edge pressing wheel 210 abuts against the upper and lower sides of the packaging box, and rolls along the packaging box, pressing the upper and lower sides of the packaging box down to make it close; synchronously, when the edge pressing is in progress, the contact 300 touches the packaging box, so that the contact 300 moves inward, and the sealing plate 301 no longer abuts against the glue outlet hole 303, so that the glue outlet tube 303 is The glue in 02 flows out and is smeared on the surface of the packaging box. When the glue in the front flows out, the first pressing wheel 208 above it then rolls and presses the glue to make the glue evenly distributed and further press the packaging box. When the shrink block 403 contacts the two sides of the packaging box, it slides inward along the shrink slope 402 due to the compression of the packaging box, so that the shrink block 403 no longer blocks the glue coating groove 401, so that the glue in the glue coating groove 401 flows out and is smeared on the two sides of the packaging box, so that the upper and lower sides and the left and right sides of the packaging box are all coated with glue; after the pressing and gluing of the upper and lower sides are completed, the packaging box continues to be transported and reaches the friction The left and right sides of the packaging box opening are in contact with the friction strip 502, and the friction strip 502 is squeezed under the friction force of the friction strip 502, and the edge strip 500 is driven to push the connecting rod 503 to rotate. Due to the inclined placement of the connecting rod 503, the side edges of the packaging box are squeezed synchronously, so that they are retracted inward, and under the initial bonding of the glue, they form an inwardly retracted state and no longer remain vertical; then, after the edge is completed, the packaging box and the stopper 102 move together to the end of the first conveyor 100. At this time, the two side edges of the packaging box are abutted against the edge pressing plate 800, and the stopper 102 moves until it abuts against the transmission strip 700, and then pushes The dynamic transmission bar 700 moves, thereby driving the driving bar 702 to move, and under the action of the moving member 701 and the second positioning groove 104, the moving direction of the driving bar 702 is fixed, thereby driving the driving bar 702 to horizontally push the driving plate 704. When the driving plate 704 moves horizontally, it drives the horizontal bar 805 to move horizontally, thereby driving the first transmission bar 802, the second transmission bar 803 and the third transmission bar 804 to unfold, so that the edge pressing plate 800 moves horizontally to the front end, thereby pressing the two side edges of the packaging box to close inward, so that the glue completely adheres to the packaging box, and the two side edges are completely closed, thereby completing the edge pressing closure of the entire bottom surface of the packaging box;Then, the packaging box is transported to the steering plate 609.
