Description

Technical Field

[0001] The utility model relates to the technical field of flipping devices, in particular to a bending and flipping device for carton packaging production and processing. Background Art

[0002] At present, with the continuous development of society, cartons, as an indispensable part of modern logistics, undertake the important responsibilities of containing, protecting products, and being aesthetically pleasing. Commonly used cartons have three layers, five layers, and seven layers are less used. Each layer is divided into inner paper, corrugated paper, core paper, and face paper. The inner and face papers are made of tea board paper and kraft paper, and the core paper is made of corrugated paper. The colors and feels of various papers are different, and the papers produced by different manufacturers are also different. For the convenience of storage, cartons are stored in the form of sheets when not in use. When needed, the sheet-shaped cardboard is formed into a rectangular box. When forming a rectangular box, carton packaging equipment is required. And when performing carton packaging, it is often necessary to flip the carton.

[0003] Chinese patent with the authorization publication number CN217320930U discloses a carton lifting and flipping device. By driving the flipping and lifting mechanism to rotate 180 degrees through a rotating shaft, the flipping and lifting of the carton are realized, with high working efficiency and low labor intensity. After the end of the carton is clamped into the flipping die box, the elastic pressing plate applies a certain elastic clamping force to the carton through the pressing block, avoiding the separation of the carton from the flipping die box due to the centrifugal force during the flipping and lifting process;

[0004] Although this carton lifting and flipping device avoids the separation of the carton from the flipping die box due to the centrifugal force during the flipping and lifting process, in the actual use process, there are usually certain limitations when the existing equipment fixes the carton, which results in poor stability of the carton during the flipping process. When the carton is placed on these devices for operation, if the fixation is not firm enough, it is very easy to slide or even fall during the flipping or moving process. This situation will not only increase the risks during the production process, but may also damage the product quality and even pose a safety hazard to the operators. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] 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.

[0025] See also Figures 1 to 4 , the utility model provides a technical solution:

[0026] A bending and turning device for carton packaging production and processing, comprising a workbench 1, support legs 2 are fixedly installed at the four corners of the lower end surface of the workbench 1, a motor 3 is fixedly installed on the front side of the lower end surface of the workbench 1, a fixing mechanism 1 is arranged on the front side of the motor 3, a fixing mechanism 2 is arranged inside the fixing mechanism 1, the fixing mechanism 1 comprises a threaded rod 4 fixedly installed at the end of the output shaft of the motor 3, threaded sleeves 5 are spirally connected to the outer surface of the threaded rod 4 on both sides, connecting rods 6 are rotatably connected to the left and right sides of the outer surface of the threaded sleeve 5, slide grooves 9 are opened on both sides of the upper end surface of the workbench 1, slide grooves 9 are slidably connected to the inside of the slide grooves 9, a top block 7 is fixedly installed on the lower end of the slide rod 8, two groups of connecting rods 6 on the same side are rotatably connected to the corresponding top blocks 7, a fixing part 10 is fixedly installed on the upper end of the slide rod 8, and a motor 2 11 is fixedly installed on the upper end of the fixing part 10.

[0027] A fixed frame 12 is fixedly installed on the end of the output shaft of the motor 2 11, a fixed column 13 is fixedly installed on the end of the fixed frame 12, a top plate 14 is fixedly installed on the end of the fixed column 13, the threaded groove on the outer surface of the threaded rod 4 is a bidirectional threaded groove, the other end of the threaded rod 4 is rotatably connected to the workbench 1, and the top plate 14, the fixed column 13, the fixed frame 12, the slide rod 8 and the slide groove 2 22 are each provided in two groups correspondingly and are symmetrically arranged.

[0028] Existing equipment usually has certain limitations when fixing cartons, which leads to poor stability of cartons during the flipping process. When cartons are placed on these devices for operation, if the fixation is not firm enough, they are prone to sliding or even falling during the flipping or moving process. This situation will not only increase the risk in the production process, but also may cause product quality damage and even bring safety hazards to operators. Therefore, the utility model can flexibly adjust according to cartons of different sizes and shapes by setting a fixing mechanism, ensuring that each carton can be properly supported and fixed, which not only helps to improve the processing quality and reduce the scrap rate caused by instability, but also fully considers the convenience and safety of operation, so that workers can quickly and accurately complete the cartons. Fixed work not only reduces the labor intensity of workers, but also greatly shortens the preparation time, thereby improving the efficiency of the entire production line. Specifically: first, place the carton between the two groups of top plates 14, and then start the motor 3 to rotate the threaded rod 4 of the motor 3, and the two groups of threaded sleeves 5 connected by the spiral transmission on the outer surface of the threaded rod 4 will move toward each other, and the two groups of threaded sleeves 5 respectively carry the two groups of connecting rods 6 for displacement, and the connecting rods 6 on the same side are rotatably connected with the top blocks 7 on the corresponding sliding rods 8. Therefore, as the threaded rod 4 rotates, the two groups of sliding rods 8 will be displaced toward each other, and the top plates 14 on the sliding rods 8 will move toward each other, so that the carton is initially clamped and fixed.

[0029] The second fixing mechanism includes an inner cavity 15 opened inside the fixing column 13, and a transmission column 16 is slidably connected inside the inner cavity 15. A limit plate 18 is fixedly installed at one end of the transmission column 16, and a spring 19 is fixedly installed between the limit plate 18 and the transmission column 16. The limit plate 18 is arranged inside the fixing frame 12. A notch 20 is opened on the outer surface of the top plate 14, and a cross bar is fixedly installed inside the notch 20. A transmission rod 21 is arranged inside the notch 20. A second slide groove 22 is opened on the front end surface of the transmission rod 21, and the second slide groove 22 is slidably connected to the cross bar inside the notch 20. A block 23 is fixedly installed at one end of the transmission rod 21. A connecting piece 17 is fixedly installed on the outer surface of the transmission column 16, and the other end of the transmission rod 21 is rotatably connected to the connecting piece 17.

[0030] When the top plate 14 is in close contact with the carton, the fixed column 13 will be driven to move toward the inner cavity 15, and the connecting piece 17 on the fixed column 13 will be moved synchronously. The connecting piece 17 is rotatably connected to one end of the transmission rod 21, and the connecting piece 17 synchronously pulls the transmission rod 21 to move backward, so that the slide groove 22 on the transmission rod 21 is slidably connected with the cross bar in the groove 20. The setting of the slide groove 22 can offset the deviation caused by the deflection of the transmission rod 21, and the block 23 at the other end of the transmission rod 21 will be in close contact with the carton. The four groups of blocks 23 are respectively in close contact with the four sides of the carton, thereby fixing the carton for a second time, and the setting of the motor 2 11 can drive the carton in the fixed state to flip.

[0031] Working principle: First, place the cardboard box between the two groups of top plates 14. Then, start the first motor 3 to rotate the threaded rod 4 of the first motor 3. The two threaded sleeves 5 spirally connected to the outer surface of the threaded rod 4 will move towards each other. The two threaded sleeves 5 respectively carry the two connecting rods 6 for displacement. The connecting rods 6 on the same side are rotatably connected to the top blocks 7 on the corresponding sliding rods 8. Therefore, with the rotation of the threaded rod 4, the two sliding rods 8 will move towards each other, and the top plates 14 on the sliding rods 8 will move towards each other to initially clamp and fix the cardboard box.

[0032] When the top plate 14 is in close contact with the cardboard box, it will drive the fixed column 13 to displace towards the inside of the inner cavity 15. The connecting piece 17 on the fixed column 13 will displace synchronously. The connecting piece 17 is rotatably connected to one end of the transmission rod 21. The connecting piece 17 synchronously pulls the transmission rod 21 to displace backward, so that the second chute 22 on the transmission rod 21 is slidably connected to the cross bar in the notch 20. The setting of the second chute 22 can offset the deviation generated by the deflection of the transmission rod 21. The clamping block 23 at the other end of the transmission rod 21 will be in close contact with the cardboard box. The four clamping blocks 23 are respectively in close contact with the four sides of the cardboard box, thereby performing secondary fixation on the cardboard box. The setting of the second motor 11 can drive the fixed cardboard box to flip.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
