Description

Technical Field

[0001] The present application relates to the technical field of packaging box production, and particularly to a turnover mechanism for packaging box production. Background Art

[0002] With the development of social economy, people's requirements for packaging boxes are getting higher and higher. Packaging box production equipment has also become a research direction for relevant manufacturers. Packaging boxes are usually made by stamping, cutting, and pasting honeycomb paperboards. Paper corner protectors are pasted at the interfaces of the paperboards to strengthen. They can be designed into different configurations such as integral type, combined type, and integrated bottom support type according to actual needs, which is more conducive to handling and loading and unloading. The packaging box is light in weight and large in load-bearing, and can be customized according to the size and specifications of items. It is mainly used to replace wooden boxes during transportation. When producing packaging boxes, it is necessary to carry out turnover processing on them.

[0003] Regarding the above related technologies, the inventor believes that the traditional turnover device for packaging box production places the workpiece on the corresponding tabletop. After one side is processed, the tabletop is then turned over so that the workpiece is on another tabletop or the surface of the workpiece is turned over to assist and facilitate subsequent operations. This will cause the turnover work to not be continuous. It is necessary to process one after another after one processing is completed, which affects production efficiency. Or an artificial turnover method is adopted. This method has a large labor intensity and is easy to damage the packaging box, and there are defects. Therefore, a turnover mechanism for packaging box production is proposed to solve the above problems.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

[0005] In order to solve the problems of the traditional turnover device for packaging box production, which places the workpiece on the corresponding tabletop, after one side is processed, the tabletop is then turned over so that the workpiece is on another tabletop or the surface of the workpiece is turned over to assist and facilitate subsequent operations. The turnover work cannot be continuous. It is necessary to process one after another after one processing is completed, which affects production efficiency. Or an artificial turnover method is adopted. This method has a large labor intensity and is easy to damage the packaging box, the present application provides a turnover mechanism for packaging box production.

[0006] The turnover mechanism for packaging box production provided by the present application adopts the following technical solutions:

[0007] A turnover mechanism for the production of packing boxes, comprising a conveyor belt and a turnover drive assembly. Three rotating rollers are sleeved inside the conveyor belt. Both ends of the three rotating rollers are rotatably connected to support plates. Among them, mounting plates are fixedly connected to the tops of the support plates at both ends of the middle rotating roller. A rotating shaft is rotatably connected inside one of the mounting plates. A U-shaped plate is fixedly connected to the outside of the rotating shaft. A servo motor is fixedly connected to the outer side wall of one of the flanges of the U-shaped plate. The output end of the servo motor penetrates through the flange of the U-shaped plate and is fixedly connected to a bidirectional lead screw. Two clamping plates are symmetrically threadedly connected to the outside of the bidirectional lead screw. The rotating roller is connected to an external driving device. When the driving device works, it can drive the rotating roller to rotate. The rotation of multiple rotating rollers can drive the conveyor belt to move. First, the opening direction of the U-shaped plate faces the conveying direction of the packing box on the conveyor belt. When the packing box is transported to the position between the two clamping plates, the servo motor is started, which drives the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw will drive the two clamping plates on its outside to approach each other, so as to clamp and fix the packing box. In addition, the turnover drive assembly drives the rotating shaft to rotate. The rotation of the rotating shaft will drive the U-shaped plate, the two clamping plates and the packing box to rotate 180 degrees, so as to realize the turnover of the packing box. After the packing box is turned over, the servo motor reverses, driving the two clamping plates to move away from each other, and the turned-over packing box will fall onto the surface of the conveyor belt, thus realizing the automatic turnover of the packing box.

[0008] Preferably, the turnover drive assembly includes a support table. A hydraulic cylinder is fixedly connected to the top of the support table. The output end of the hydraulic cylinder is fixedly connected to a rack. A gear is meshed with the outside of the rack. One end of the rotating shaft away from the mounting plate penetrates through the other mounting plate and is fixedly connected to the gear. By starting the hydraulic cylinder, the hydraulic cylinder drives the rack to move. The movement of the rack drives the meshing gear to rotate. The rotation of the gear drives the rotating shaft to rotate.

[0009] Preferably, a convex block is installed at one end of the rotating shaft away from the gear. Two limiting blocks are symmetrically and fixedly connected to the surface of the mounting plate near the convex block and on both sides of the rotating shaft. When the rotating shaft rotates, the convex block rotates accordingly. When the convex block is blocked by the limiting block, the rotating shaft stops rotating, so as to limit the rotation angle of the rotating shaft. The maximum rotation angle of the rack driving the gear is 180 degrees.

[0010] Preferably, rubber pads are arranged on the opposite sides of the two clamping plates. The rubber pads can prevent the two clamping plates from damaging the packing box when clamping and fixing the packing box.

[0011] Preferably, the side wall of the clamping plate close to the inner wall of the web of the U-shaped plate is closely attached to the inner wall of the web of the U-shaped plate, so as to prevent the clamping plate from rotating and shifting when moving on the outside of the bidirectional lead screw, thus ensuring the stability of the clamping plate when moving on the outside of the bidirectional lead screw.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] The conveyor belt drives the packing box to move. When the packing box is transported to the position between the two clamping plates, under the action of the servo motor and the bidirectional lead screw, the two clamping plates outside it will be driven to approach each other, thereby realizing the clamping and fixing of the packing box. In addition, the rotating shaft is driven to rotate by the flipping drive assembly, and the rotation of the rotating shaft will drive the U-shaped plate, the two clamping plates and the packing box to rotate 180 degrees, thereby realizing the flipping of the packing box. After the packing box is flipped, the servo motor reverses, driving the two clamping plates to move away from each other, and the flipped packing box will fall onto the surface of the conveyor belt, thus realizing the automatic flipping of the packing box. Compared with the prior art, the present application can realize the automatic flipping of the packing box, has a high degree of automation, improves production efficiency, and effectively protects the packing box.

Detailed Description of the Invention

[0019] The following further elaborates on the present application in conjunction with the attached Figures 1-4 drawings.

[0020] The embodiment of the present application discloses a flipping mechanism for the production of packing boxes. Refer to Figure 1 , Figure 2 and Figure 4, including a conveyor belt 1 and a flipping drive assembly. Inside the conveyor belt 1, three rotating rollers 2 are sleeved. Both ends of the three rotating rollers 2 are rotatably connected to support plates 3. Among them, on the top of the support plates 3 at both ends of the middle rotating roller 2, mounting plates 4 are fixedly connected; inside one of the mounting plates 4, a rotating shaft 5 is rotatably connected. Outside the rotating shaft 5, a U-shaped plate 6 is fixedly connected. On the outer side wall of one flange of the U-shaped plate 6, a servo motor 7 is fixedly connected. The output end of the servo motor 7 penetrates through the flange of the U-shaped plate 6 and is fixedly connected to a bidirectional lead screw 8. Outside the bidirectional lead screw 8, two clamping plates 9 are symmetrically threadedly connected. The rotating roller 2 is connected to an external driving device. When the driving device works, it can drive the rotating roller 2 to rotate. The rotation of multiple rotating rollers 2 can drive the conveyor belt 1 to move. First, the opening direction of the U-shaped plate 6 faces the conveying direction of the packaging box on the conveyor belt 1. When the packaging box is transported to the position between the two clamping plates 9, the servo motor 7 is started, which drives the bidirectional lead screw 8 to rotate. The rotation of the bidirectional lead screw 8 will drive the two clamping plates 9 on its outside to approach each other, thereby realizing the clamping and fixing of the packaging box. In addition, the flipping drive assembly drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 will drive the U-shaped plate 6, the two clamping plates 9 and the packaging box to rotate 180 degrees, thereby realizing the flipping of the packaging box. After the packaging box is flipped, the servo motor 7 rotates in reverse, which drives the two clamping plates 9 to move away from each other. Thus, the flipped packaging box will fall onto the surface of the conveyor belt 1, thereby realizing the automatic flipping of the packaging box.

[0021] Refer to Figure 1 and Figure 3 , the flipping drive assembly includes a support platform 10. On the top of the support platform 10, a hydraulic cylinder 11 is fixedly connected. The output end of the hydraulic cylinder 11 is fixedly connected to a rack 12. Outside the rack 12, a gear 13 is meshed. One end of the rotating shaft 5 far from the mounting plate 4 penetrates through the other mounting plate 4 and is fixedly connected to the gear 13. By starting the hydraulic cylinder 11, the start of the hydraulic cylinder 11 drives the rack 12 to move. The movement of the rack 12 will drive the meshed gear 13 to rotate. The rotation of the gear 13 will drive the rotating shaft 5 to rotate.

[0022] Refer to Figure 4 , on one end of the rotating shaft 5 far from the gear 13, a convex block 14 is installed. On the surface of the mounting plate 4 close to the convex block 14 and symmetrically on both sides of the rotating shaft 5, two limiting blocks 15 are fixedly connected. When the rotating shaft 5 rotates, the convex block 14 rotates accordingly. When the convex block 14 is blocked by the limiting block 15, the rotating shaft 5 stops rotating, thereby limiting the rotation angle of the rotating shaft 5. The maximum rotation angle of the rack 12 driving the gear 13 is 180 degrees.

[0023] Refer to Figure 2 and Figure 4, rubber pads 16 are provided on the opposite sides of the two clamping plates 9. By means of the rubber pads 16, damage to the packing box can be avoided when the two clamping plates 9 clamp and fix the packing box.

[0024] Referring to Figure 2 and Figure 4 , the side wall of the clamping plate 9 close to the inner wall of the web of the U-shaped plate 6 is in close contact with the inner wall of the web of the U-shaped plate 6, so that the rotation deviation of the clamping plate 9 can be avoided when it moves outside the bidirectional lead screw 8, thereby enhancing the stability of the clamping plate 9 when it moves outside the bidirectional lead screw 8.

[0025] The implementation principle of the flipping mechanism for packing box production in the embodiment of the present application is as follows: The rotating roller 2 is connected to an external driving device. When the driving device operates, it can drive the rotating roller 2 to rotate. The rotation of multiple rotating rollers 2 can drive the conveyor belt 1 to move. First, the opening direction of the U-shaped plate 6 faces the conveying direction of the packing box on the conveyor belt 1. When the packing box is transported to the position between the two clamping plates 9, the servo motor 7 is started. The servo motor 7 is preferably of the HBS57 type, which drives the bidirectional lead screw 8 to rotate. The rotation of the bidirectional lead screw 8 will drive the two clamping plates 9 outside it to approach each other, thereby realizing the clamping and fixing of the packing box. By means of the rubber pads 16, damage to the packing box can be avoided when the two clamping plates 9 clamp and fix the packing box. In addition, by starting the hydraulic cylinder 11, the hydraulic cylinder 11 is preferably of the TN16-20 type. When the hydraulic cylinder 11 is started, it drives the rack 12 to move. The movement of the rack 12 will drive the engaged gear 13 to rotate. The rotation of the gear 13 will drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 will drive the U-shaped plate 6, the two clamping plates 9 and the packing box to rotate 180 degrees, thereby realizing the flipping of the packing box. After the packing box is flipped, the servo motor 7 rotates in the reverse direction, driving the two clamping plates 9 to move away from each other. Then the flipped packing box will fall onto the surface of the conveyor belt 1, thus realizing the automatic flipping of the packing box. When the rotating shaft 5 rotates, the convex block 14 rotates accordingly. When the convex block 14 is blocked by the limiting block 15, the rotating shaft 5 stops rotating, so that the rotation angle of the rotating shaft 5 can be limited. The maximum angle of rotation of the rack 12 driving the gear 13 is 180 degrees.
