[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 A double-layer conveying and stacking machine for packaging boxes in this embodiment includes a double-layer conveying platform 1 and a lifting and docking component 2 installed at the head end of the double-layer conveying platform 1 for connecting packaging boxes to the upper layer, and a stacking mechanism 3 installed on the upper layer at the tail end of the double-layer conveying platform 1, and a baffle 7 is fixed at the tail end of the upper layer of the double-layer conveying platform 1.

[0020] In the above structure, first, the docking end of the lifting and docking assembly will dock with the lower layer of the double-layer conveyor platform until the lower layer of the double-layer conveyor platform transports the package box to the docking end, and then the lifting and docking assembly will move the package box to the upper layer until the package box is transported to the connection with the baffle. The stacking mechanism will drive the package box to lift and support, and then repeat the above principle, so that the package boxes can be stacked together, thereby realizing the effect of automatic stacking, thereby reducing production costs and improving work efficiency.

[0021] Among them, the stacking mechanism 3 includes a support frame 301 located at the tail end of the double-layer conveyor platform 1, two relatively distributed upper plates 302 are fixed on the top of the support frame 301, and two side plates 316 are fixed at the border of the support frame 301 and located between the two upper plates 302, and a lifting part is installed at the middle section of the support frame 301, and the lifting part is staggered with the rollers on the double-layer conveyor platform 1, three support plates 303 are fixed on the upper plate 302, and a support part is fixed at the bottom of the support plate 303, and a guide plate 310 is connected to the bottom of the support part. When the double-layer conveyor table moves the package box to the tail end of the upper layer and is located above the lifting part, the lifting part drives the package box to move upward. At the same time, the guide plate can play a guiding and limiting role to prevent the package box from shifting during the upward movement. During the upward movement, the support part will be pushed from bottom to top to change the angle, so that the package box continues to move upward until the package box is above the support part. At the same time, the support part is reset, so the lifting part can also be reset to support the package box through the support part. Repeating the above operations can make the packages stacked together. The support plate and the side plate can limit the stacked packages. In summary, the operation of automated stacking and palletizing can be realized.

[0022] like Figure 3In the direction shown, the lifting part includes a lifting cylinder 313 installed on the left and right sides of the support frame 301 and lifting rods 314 distributed on both sides of the lifting cylinder 313. A lifting frame 315 connected to the lifting rod 314 is fixed between the ejection ends of the two lifting cylinders 313. The lifting surface of the lifting frame 315 is located in the gap between the rollers of the double-layer conveyor 1. When the lifting frame is driven by the lifting cylinder to lift, the lifting frame will be lifted from the rollers of the upper layer of the double-layer conveyor, and can be lifted to a certain height and then reset to the bottom of the rollers, so as not to affect the entry of the lower group of packaging boxes, thereby realizing the lifting effect on the packaging boxes.

[0023] In addition, two propulsion cylinders 311 are installed on the upper plate 302 on the right side, and a push plate 312 opposite to the upper plate on the left side is fixed between the ejection ends of the two propulsion cylinders 311, and three support plates 303 on the right side are fixed on the push plate 312. Through the ejection and recovery of the propulsion cylinders, the support plates can be driven to adjust their positions through the push plates, so that the distance between the relatively distributed guide plates and the support parts can be adjusted, so that it can adapt to the stacking operation of packaging boxes of different sizes.

[0024] like Figure 4 In the direction shown, the support part includes an H-shaped block 304 fixed at the bottom of the support plate 303, and three inner columns 305 are rotatably connected to the inner side of the H-shaped block 304. The three inner columns 305 are divided into a front column, a rear column and a lower column. A wheel block 307 is fixed to the outer side of the rear column. Waist holes 306 are provided on the left and right sides of the wheel block 307 and the H-shaped block 304. The front column is inserted into the waist hole 306 of the wheel block 307 for movement, and the rear column is located in the waist hole 306 on the H-shaped block 304 for movement. The lower column is located at one-third of the lower side of the wheel block 307 for support, and two tension springs 308 connected to the back of the wheel block 307 are installed on the inner side of the H-shaped block 304. When the packing box moves upward, it will contact the wheel block and move in the waist holes of the front column and the rear column, so that the wheel block has room to move, so that one end of the wheel block is pushed upward, and the tension spring is stretched at the same time, until the packing box moves to the top of the wheel block, the tension spring drives the wheel block to reset, the lower column supports the wheel column, and the waist hole on the H-block limits the upward movement of the rear column, so that the wheel block supports the packing box, and when the next packing box is pushed up, the above operation is repeated, and the wheel block can move smoothly on the wheel body of the wheel block.

[0025] like Figure 2In the direction shown, the lifting and docking assembly 2 includes a frame 201 and a guide rod 202 installed at the head end of the double-layer conveyor platform 1, and lifting cylinders 203 and guide columns 204 distributed on both sides of the lifting cylinders 203 are installed at the front and rear frames of the frame 201. A lifting frame 205 connected to the top of the guide column 204 is fixed between the ejection ends of the two lifting cylinders 203, and the right side of the bottom of the lifting frame 205 is slidably connected to the guide rod 202. A lifting and conveying platform 206 that can be docked with the upper and lower layers of the double-layer conveyor platform 1 is fixedly installed on the frame of the lifting frame 205, and a side stop 207 is fixed on the right side of the lifting and conveying platform 206. First, the filled packaging box will be transported to the tail end through the bottom of the double-layer conveyor table until it is located on the lifting conveyor table and is attached to the side block. The lifting cylinder will drive the lifting conveyor table to move up through the lifting frame until it docks with the upper layer of the double-layer conveyor table. Then the lifting conveyor table will operate to transfer the packaging box to the upper layer, thereby changing the moving direction of the packaging box and completing the transplanting operation.

[0026] In order to prevent the packaging box from being deflected during transportation, two groups of linear modules 4 and upper push cylinders 6 are installed on the lifting and conveying platform 206 and the upper double-layer conveying platform 1, one of which is marked with two, and the moving ends of the two adjacent linear modules 4 are fixed with relatively distributed side plates 5. When the packaging box is located on the upper layer of the lifting and conveying platform or the double-layer conveying platform, the operation of the linear module can drive the two side plates to clamp together, so as to correct and guide the transportation of the packaging box, prevent the packaging box from being deflected during transportation and affect the subsequent palletizing. At the same time, during the transportation process, the lifting of the upper push cylinder can limit the position of the packaging box and achieve the effect of pre-waiting.

[0027] The working principle of the above embodiment is:

[0028] First, start the propulsion cylinder to drive the push plate to move, so that the support plate on the push plate moves, so that the size of the box is matched between the two guide plates, and then the packaged box is placed on the double-layer conveyor table until it is transferred to the lifting conveyor table and abuts against the side stop. At this time, the linear module runs the side plate to clamp the box, so it can correct the box. The lifting cylinder drives the lifting frame to move up, so that the lifting conveyor table docks with the upper layer of the double-layer conveyor table and conveys it to the upper layer. When moving on the upper layer of the double-layer conveyor table, the linear module drives the side plate to clamp and correct the side plate again, and at the same time guides the box to be conveyed to the tail end. When the upper layer of the double-layer conveyor table reaches a certain amount, the upper cylinder on the lifting conveyor table is lifted up to limit the box on the lifting conveyor table to play a pre-waiting role. The lifting cylinder drives the lifting frame to lift up, so that the packaging box can be lifted. During the lifting process, it will be guided to rise by the guide plate, and the wheel block will be pushed up. The wheel block can move on the front column, and the rear column will also move on the H-block, so that the wheel block will be tilted to stretch the tension spring until it reaches a certain angle. After the packaging box is located above the wheel block, the wheel block has no extrusion force and is reset under the elastic force of the tension spring. Then, with the support of the lower column and the limit of the rear column and the waist hole, it can support the packaging box. Then repeat the above operations to realize automatic stacking, which can effectively improve production efficiency and reduce production costs.
