[0024] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] like Figure 1 to Figure 8 As shown, an embodiment of the present application provides a carton side bonding device, including: a workbench 100, a limiting mechanism 200, a folding mechanism 300, and a rolling mechanism 400.

[0026] A through portion 101 is provided on the top surface of one end of the workbench 100 in the length direction, and a plurality of first conveying wheels 102 and second conveying wheels 103 are arranged in a rectangular shape on one side and one end of the through portion 101, and the conveying directions of the first conveying wheels 102 and the second conveying wheels 103 are perpendicular to each other, that is, the rotation axis of the first conveying wheel 102 is parallel to the length direction of the through portion 101, and the rotation axis of the second conveying wheel 103 is parallel to the width direction of the through portion 101, for conveying cardboard; the limiting mechanism 200 includes a side plate 201 installed at one end of the workbench 100 in the length direction and a second conveying wheel 103. The limiting plate 203 in the area is provided with a baffle 202 which is movable along the length direction of the side plate 201. The baffle 202 and the side plate 201 are perpendicular to each other and are used to abut against one end of the cardboard. The side plate 201 applies a limit to one side of the cardboard. The limiting plate 203 is movable along the width direction of the workbench 100, and a pressing plate 204 which is movable along the vertical direction is provided inside. A plurality of limiting wheels 205 are provided at the bottom of the pressing plate 204 along its length direction, which are used to apply a downward force to the bent cardboard, thereby pressing the cardboard tightly to prevent it from shifting during the side gluing process. The folding mechanism 300 includes The first folding assembly includes a first folding assembly and a second folding assembly respectively arranged on both sides of the length direction of the workbench 100. The first folding assembly includes a first top plate 301 arranged in the through-portion 101 and moving synchronously with the limiting plate 203. The first top plate 301 is arranged to move in the vertical direction, and is used to push one end of the paperboard upward and make the paperboard in an L shape. A push plate 302 moving along the width direction of the first top plate 301 is penetrated on the side of the first top plate 301, and is used to apply a horizontal force to the vertical part of the paperboard, so that the vertical part of the paperboard is transformed into a horizontal state, thereby realizing the bending of the paperboard. The second folding assembly includes a first top plate 301 arranged on the inner side of the limiting plate 203. A second top plate 303 is arranged to move vertically and in the width direction of the workbench 100, and is used to lift the other end of the cardboard upwards, so that the cardboard becomes L-shaped again; the rolling mechanism 400 includes a horizontal plate 401 arranged at the other end in the length direction of the workbench 100 and moving vertically and in the width direction of the workbench 100, and a bottom plate of the horizontal plate 401 is provided with a plurality of pressing wheels 402 along its length direction. When the horizontal plate 401 moves along the width direction of the workbench 100, the vertical part of the cardboard is forced to deflect around the fold, thereby converting the vertical part of the other end of the cardboard into a horizontal state, and then the horizontal plate 401 moves downward to press the side of the carton.

[0027] Specifically, a through slot 206 is provided on the side of the side panel 201 at one end, one end of the baffle plate 202 passes through the through slot 206 and a first screw 207 is provided on the side, the first screw 207 is passed through the protrusion 208 and is locked with a nut, and the protrusion 208 is installed on the outside of the side panel 201. When cartons of different sizes need to be processed, the baffle plate 202 is moved along the through slot 206 and then the first screw 207 is locked with a nut.

[0028] Specifically, a plurality of convex plates 209 are provided on the side of the pressing plate 204 along its length direction. The convex plates 209 pass through the limiting plate 203 and are sleeved on the vertical rod 210. Both ends of the vertical rod 210 are installed on the connecting block 211. The connecting block 211 is installed on the outer side of the limiting plate 203. A first spring 212 is sleeved on the vertical rod 210. Both ends of the first spring 212 are respectively abutted against the convex plate 209 and the connecting block 211 located above, and are always in a compressed state. After the paperboard is bent for the first time by the first bending assembly, one end of the paperboard is flush with the inner side of the limiting plate 203. Then the cardboard is moved from the area of ​​the first conveying wheel 102 to the area of ​​the second conveying wheel 102. During the movement of the cardboard, one end of the cardboard is limited by the limiting plate 203, and the cardboard will contact the limiting wheel 205. At the same time, under the action of the first spring 212, the limiting wheel 205 has a margin for moving up and down, so that the cardboard can move smoothly under the action of external force. At the same time, the first spring 212 will apply a downward force. After stopping applying external force to the cardboard, the limiting wheel 205 will press the cardboard again to facilitate the subsequent side bonding operation.

[0029] Specifically, the bottoms of the first top plate 301 and the second top plate 303 are both sleeved on the cross bar 304, one end of the cross bar 304 is connected to the movable end of the first vertical lifting mechanism, and the first vertical lifting mechanism is installed at the bottom of the workbench 100. When the cardboard needs to be bent, the first top plate 301 or the second top plate 303 is driven to move upward by the first vertical lifting mechanism, which will force the end of the cardboard to rotate around the crease until the cardboard is L-shaped, and the top of the first top plate 301 and the second top plate 303 are both curved on one side close to the center of the workbench 100, which is more conducive to deflecting the cardboard and avoiding damage to the cardboard during the bending process due to the side edges of the first top plate 301 or the second top plate 303 being too sharp.

[0030] Specifically, one side of the push plate 302 away from the baffle 202 is arc-shaped, and the other side is connected to the moving end of the first horizontal linear mechanism. The first horizontal linear mechanism is installed on the first top plate 301. When the cardboard is bent for the first time and the cardboard is L-shaped, the push plate 302 is driven to move by the first horizontal linear mechanism, thereby forcing the vertical part of the cardboard to continue to deflect until the vertical part of the cardboard is deflected to a horizontal state, and then an external force can be applied to the cardboard to move it to the inner side of the limiting plate 203.

[0031] Specifically, in order to avoid interference between the second top plate 303 and the second conveying wheel 103, the second top plate 303 is configured to be toothed, and a plurality of elongated holes 104 are provided on the workbench 100 which pass through the workbench 100 vertically, and the elongated holes 104 and the plurality of rows of second conveying wheels 103 are alternately arranged, and the teeth of the second top plate 303 are located in the elongated holes 104.

[0032] Specifically, a vertically arranged slide groove 305 is provided on the side of the second top plate 303 and penetrates on both sides. A movable ring 306 is slidably fitted in the slide groove 305. The movable ring 306 is sleeved on the second screw rod 307 and locked with a nut. The second screw rod 307 is installed at the bottom of the workbench 100, so that the distance between the second top plate 303 and the limit plate 203 can be adjusted according to the size of the cardboard, thereby improving versatility. The adjustment process only requires moving the second top plate 303 along the axis of the second screw rod 307, and then locking the movable ring 306 with a nut.

[0033] Specifically, a plurality of connecting rods 403 are provided on the top surface of the transverse plate 401, and the connecting rods 403 are penetrated in the mounting plate 404. A second spring 406 is sleeved on the connecting rod 403. The two ends of the second spring 406 respectively abut against the mounting plate 404 and the transverse plate 401, and are always in a compressed state. A retaining ring 407 is provided on the upper end of the connecting rod 403 for abutting against the top surface of the mounting plate 404. The mounting plate 404 is connected to the moving end of the second vertical lifting mechanism. The second vertical lifting mechanism is installed on a moving frame 405, and the moving frame 405 is sleeved on a guide rod 408 and connected to the moving end of the second horizontal linear mechanism. The guide rod 408 and the second horizontal linear mechanism are both installed above the workbench 100 and arranged along its width direction. After the cardboard has undergone the first bend and is located in the area of ​​the second conveying wheel 103, the other end of the cardboard is moved in through the second top plate 303. The paperboard is deflected to make it L-shaped again. Before the vertical part of the paperboard is deflected to the horizontal state, glue is dripped on the side of the paperboard. The process of dripping glue can be performed manually or by using an automated dripping device. Then, the second horizontal linear mechanism drives the movable frame 405 to move toward the limiting plate 203, and the horizontal plate 401 will contact the vertical part of the paperboard and force it to rotate around the fold until the vertical part of the paperboard is transformed into a horizontal state. At this time, the second vertical lifting mechanism drives the mounting plate 404 to move downward, so that the pressing wheel 402 contacts the paperboard. At this time, the second spring 406 is further compressed, so that the two side edges of the paperboard are bonded together. At the same time, an external force is applied to the paperboard to make it move along the length direction of the workbench 100. Under the pressure of the pressing wheel 402, the side edges of the paperboard are bonded more firmly.

[0034] Specifically, a protrusion is provided at one end of the first top plate 301 close to the limiting plate 203. The protrusion is located outside the limiting plate 203 and slidably cooperates with it, so that the first top plate 301 can move synchronously with the limiting plate 203 to ensure the bending effect of the paperboard.

[0035] Specifically, the workbench 100 is provided with a plurality of through grooves 105 arranged along its length direction and located on one side of the through portion 101. A movable plate 106 is penetrated in the through groove 105. The movable plate 106 is in an inverted L shape and is connected to a bottom plate 107. The movable plate 106 is used to move the bent cardboard from the area of ​​the first conveying wheel 102 to the area of ​​the second conveying wheel 103. The bottom plate 107 is connected to the moving end of the third horizontal linear mechanism. The third horizontal linear mechanism is installed at the bottom of the workbench 100. When the cardboard is pushed to the area of ​​the first conveying wheel 102 on the workbench 100, the cardboard is located on the movable plate 106. Below the horizontal part, the movable plate 106 can provide vertical limitation for the cardboard during the first bending, so as to ensure the smooth progress of the first bending operation. After the first bending, the deflected part of the cardboard is located above the horizontal part of the movable plate 106. In order to ensure the smooth progress of the subsequent bonding operation, it is necessary to limit the cardboard through the limiting wheel 205 during the process of moving it to the area of ​​the second conveying wheel 103. For the transfer of the cardboard after the first bending, it is only necessary to drive the movable plate 106 toward the second conveying wheel 103 through the third horizontal linear mechanism.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
