[0002] Packing boxes are mainly used for packaging and transportation of goods, which can facilitate the transportation, loading and unloading, and warehousing of goods. Packing boxes mainly include wooden packing boxes and paper packing boxes. In the specific use process, appropriate packing boxes can be selected for packaging and use according to the characteristics of the goods to be transported or loaded. In the food production process, the produced food needs to be uniformly packed into food packaging boxes, which is convenient for subsequent transportation and storage. Among them, food packaging boxes usually need to be stacked together during actual storage and transportation, which can improve the efficiency of storage and transportation of food packaging boxes. However, in the stacking process of food packaging boxes, workers are usually required to perform manual corrections from time to time to reduce the problem of tilting of food packaging boxes during stacking, thereby increasing the labor intensity of workers. In order to improve the timeliness of correction, workers need to concentrate their attention for a high intensity and for a long time, which will accelerate the mental fatigue of workers, thereby increasing the probability of safety hazards in the production process. If stacking correction is not performed, the edges of the packaging box pile are prone to misalignment, making them not flat enough, which will increase the difficulty of packaging box transportation and increase the probability of damage at the edges of the packaging box, affecting subsequent production efficiency.

DETAILED DESCRIPTION

[0017] Reference Figures 1 to 4 As shown, the utility model provides an automatic stacking machine for food packaging boxes, including: a bottom plate 1 and a fixed plate 7, wherein the lower surface of the bottom plate 1 is symmetrically connected to the support plate 16, and the end surface of the bottom plate 1 is fixedly connected to the fixed plate 7 through the vertical plate 2, and a main slide groove is provided on the surface of the vertical plate 2, and a main screw rod 14 is movably connected in the main slide groove through a bearing, and the lower surface of the vertical plate 2 is fixedly connected to a main motor 13, and the main motor 13 is connected to the main screw rod 14 through a coupling, and at the same time, a main slider 3 is slidably connected in the main slide groove through a screw-connected main screw rod 14, and the end surface of the main slider 3 is fixedly connected to the moving plate 5, and the moving plate 5 is fixedly connected to the moving plate 5.

The two ends of the fixed rod 9 are respectively fixedly connected to the push plate 10 and the moving rod 11, and the end of the moving rod 11 away from the fixed rod 9 is slidably connected to the moving groove opened in the cross plate 15 through a spring, and the cross plate 15 is fixedly connected to the upper surface of the fixed plate 7, and the upper surface of the cross plate 15 is fixedly connected to the auxiliary motor 12, the auxiliary motor 12 is engaged with the rack 17 through an incomplete gear, and the rack 17 is fixedly connected to the groove opened on the surface of the moving rod 11.

[0018] In this embodiment, the food packaging box is transported to the upper surface of the carrier plate 4 by the conveying component, and the pressure sensor transmits the pressure data of the carrier plate 4 to the PLC component in real time. Then, when the pressure data of the carrier plate 4 changes, the PLC component starts the main motor 13, and the main motor 13 drives the main screw 14 to rotate through the coupling, and the main screw 14 drives the moving plate 5, the pressure sensor, the carrier plate 4 and the food packaging box to automatically move down a certain distance through the main slider 3 that is screwed, so that the upper surface height of the food packaging box on the carrier plate 4 is lower than the upper surface height of the transition plate 18, which facilitates the automatic stacking of the subsequent food packaging boxes. At the same time, the PLC component controls the auxiliary motor 12 to rotate at a low speed, and the transmission of the auxiliary motor 12 The output shaft drives the incomplete gear to rotate, and the tooth groove groups on both sides of the incomplete gear will push the corresponding meshing rack 17 to move, and the rack 17 will push the moving rod 11 to move synchronously. While squeezing the corresponding spring, the moving rod 11 will also drive the fixed rod 9 and the push plate 10 to move synchronously.

Therefore, the two groups of push plates 10 can perform periodic relative motion, so that the food packaging boxes can be automatically corrected and sorted during the stacking process, ensuring the flatness of the edge of the food packaging box pile, reducing the labor intensity of workers, and improving the safety of workers in the production process.

[0019] At the same time, the main motor 13, the auxiliary motor 12 and the pressure sensor are electrically connected to the PLC component respectively, and the PLC component is a common brand model on the market, and the parts of the circuits, electronic components and modules involved in this application are all existing technologies, which can be fully implemented by technical personnel in this field, and the content protected by this utility model does not involve improvements to software and methods.

[0020] As a preferred embodiment, the two groups of support plates 16 fixedly connected to the lower surface of the base plate 1 are both rectangular structures, and the cross-section of the support plate 16 is a dovetail structure, while the buffer layer fixedly connected to the lower surface of the support plate 16 is a rectangular structure. At the same time, the cross-section formed by the combination of the base plate 1 and the support plate 16 is a dovetail structure.

[0021] In this embodiment, if Figure 1 and Figure 2 The structural setting of the support plate 16 can help enhance the stability of the automatic stacking machine when it is placed. At the same time, the buffer layer is made of soft rubber material, which can help enhance the shock absorption effect of the automatic stacking machine.

[0022] As a preferred embodiment, the vertical plate 2 has a rectangular structure, a group of main slide grooves are opened in the middle of the surface of the vertical plate 2, and two groups of auxiliary slide grooves are opened symmetrically on both sides of the surface of the vertical plate 2, and the main slide grooves and the auxiliary slide grooves are both long strip structures. At the same time, the vertical plate 2, the main slide grooves and the auxiliary slide grooves are combined together to form a U-shaped structure.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the formation of the main chute and the secondary chute can assist in enhancing the stability of the moving plate 5 when moving on the surface of the vertical plate 2, thereby ensuring that the moving plate 5 can drive the load plate 4, the pressure sensor, and the food packaging box to move smoothly.

[0024] As a preferred embodiment, two groups of fixing plates 7 are fixedly connected to both sides of the upper end of the vertical plate 2. Both groups of fixing plates 7 are square structures, and the side cross-section formed by the combination of the fixing plates 7, the vertical plate 2, and the bottom plate 1 is a U-shaped structure. At the same time, a transition plate 18 is fixedly connected to the lower end of the side of the fixing plate 7 away from the vertical plate 2. The transition plate 18 is an I-shaped structure, and the auxiliary roller 19 movably connected through a bearing inside the transition plate 18 is a cylindrical structure. An auxiliary motor is fixedly connected to the outer end face of the transition plate 18, and the auxiliary motor is connected to the auxiliary roller 19 through a coupling.

[0025] In this embodiment, as Figure 2 and Figure 3 , when it is necessary to enhance the stacking effect of the food packaging boxes, the PLC component starts the electrically connected auxiliary motor. The auxiliary motor drives the auxiliary roller 19 to rotate. Then, when the food packaging box passes through the upper surface of the transition plate 18, the auxiliary roller 19 can assist in pushing the movement of the food packaging box, so that after the food packaging box leaves the conveying component, it can smoothly move above the load plate 4, avoiding the situation that the food packaging box stays on the surface of the transition plate 18, and ensuring the quality and efficiency of subsequent stacking.

[0026] As a preferred embodiment, both the moving plate 5 and the load plate 4 are rectangular structures.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the main slider 3 and the secondary sliders 6 are respectively adapted to the sizes of the main chute and the secondary chute, thereby being able to assist in enhancing the stability of the moving plate 5 during movement. At the same time, the setting of the convex strips on the upper surface of the load plate 4 enables the group of food packaging boxes at the bottom of the food packaging box stack not to completely fit the surface of the load plate 4, thus facilitating subsequent workers to quickly remove the food packaging box stack.

[0028] As a preferred embodiment, the fixing rod 9 has a rectangular structure, and the push plate 10 to which the fixing rod 9 is fixed has a square structure, and the push plate 10 is symmetrically connected to one side of the fixing plate 7 close to four groups of guide rods 8, the four groups of guide rods 8 are all cylindrical structures, and guide holes are opened on the surface of the fixing plate 7 corresponding to the position of the guide rods 8.

[0029] In this embodiment, if Figure 1 , Figure 2 and Figure 3 The sizes of the guide rod 8 and the guide hole are matched, which can reduce the probability of accidental shaking of the guide rod 8. The setting of the guide rod 8 can help enhance the stability of the push plate 10 when it moves, and ensure the correction and leveling effect of the push plate 10 at the edge of the food packaging box pile.

[0030] As a preferred embodiment, the horizontal plate 15 has a rectangular structure, and the two groups of movable grooves opened in the horizontal plate 15 are both long strip structures, and the two groups of movable grooves are symmetrically distributed around the center, and the opposite ends of the two groups of movable grooves are connected through a transmission groove, and the movable rod 11 slidingly connected in the movable groove has an L-shaped structure. At the same time, the incomplete gear connected to the auxiliary motor 12 is movably connected in the transmission groove, and two groups of arc-shaped tooth grooves are symmetrically opened on both sides of the incomplete gear.

[0031] In this embodiment, if Figure 1 , Figure 2 and Figure 4 The sizes of the moving groove and the moving rod 11 are matched, which can help enhance the stability of the moving rod 11 when it moves, and during the rotation of the incomplete gear, the two sets of tooth grooves will synchronously engage with the racks 17 on both sides, and will also synchronously disengage the engaged racks 17. Therefore, when the incomplete gear is not connected to the rack 17, the rack 17 and the moving rod 11 can be reset under the action of the corresponding spring, so it is convenient for the next meshing connection between the incomplete gear and the rack 17, thereby realizing the periodic reciprocating movement of the push plate 10 and the moving rod 11.

[0032] The automatic stacking machine for food packaging boxes of the present invention enables the push plate 10 to perform periodic relative movement through the cooperation of the vertical plate 2, the main screw rod 14, the main motor 13, the horizontal plate 15, the auxiliary motor 12, the moving rod 11 and the fixed rod 9, and then can perform corresponding stacking corrections on the food packaging boxes on the surface of the loading plate 4, thereby improving the quality of stacking of food packaging boxes, reducing the workload of workers, and avoiding workers from being highly concentrated for a long time, thereby effectively improving the safety of workers in the production process.
