Description

Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a flattening device for packaging carton production. Background Technique

[0002] A flattening machine is a common mechanical device widely used in industrial production. It is mainly used to flatten the surface of materials. The flattening machine mainly consists of a frame, a roller system, an electrical control system, etc. Among them, the frame provides stable support for the flattening machine, and the roller system is the key part to achieve the flattening effect.

[0003] When optimizing the existing flattening device for packaging carton production, most of them are reflected in improving the buffering ability during flattening to prevent the cartons from being damaged and improving the product quality. For example, the Chinese utility model patent with the application number CN202020431390.9 discloses "A flattening device for packaging carton production". In this device, it includes a frame, a conveying mechanism, the conveying mechanism is arranged inside the frame, a limiting mechanism, the limiting mechanism is fixedly connected to the left side of the top of the frame, a pretreatment mechanism, the pretreatment mechanism is fixedly connected to the top of the frame, and a flattening mechanism, the flattening mechanism is fixedly connected to the right side of the top of the frame. Through the limiting mechanism, it can be ensured that the cartons will not be skewed when being conveyed on the conveying mechanism, preventing carton damage caused by flattening mistakes. Through the pretreatment mechanism, the cartons can be preliminarily flattened first, reducing the height of the cartons and making it more convenient for the subsequent flattening mechanism to work. Through the buffer rods, buffer springs and rubber pads, the buffering ability during flattening can be greatly improved, preventing the cartons from being damaged and improving the product quality.

[0004] Although the above-mentioned flattening device for packaging carton production has certain advantages in improving the buffering ability during flattening, preventing the cartons from being damaged and improving the product quality, it still has certain drawbacks: when different cartons are being flattened, the required roller specifications are different, so personnel need to frequently replace the rollers. The disassembly and assembly are inconvenient and easily increase the operability of personnel. And after the rollers are installed, if the width is less than the width of the block frame, they cannot be installed properly, resulting in the phenomenon of the rollers moving left and right.

The bearing seats 42 are fixedly installed on the inner wall surfaces at the left and right ends of the block frame 41. The shaft rod 43 is connected to the bearing seats 42 and movably matched. The anti-offset structure 44 is arranged on the inner side of the block frame 41. The shaft rod 43 passes through the inside of the clamping structure 45. The clamping structure 45 is installed at the side end of the flattening roller 46 with a gap. The side end of the block frame 41 is slidably matched with the vertical frame 3. The middle of the upper end surface of the block frame 41 is fixedly connected to the output end of the hydraulic cylinder 5. The anti-offset structure 44 and the clamping structure 45 are respectively provided with two groups and are symmetrically arranged left and right. The flattening roller 46 is installed through the shaft rod 43 and can be replaced with flattening rollers 46 of different diameter widths according to the flattening requirements.

[0028] Please refer to Figure 3-4 , a flattening device for packaging carton production, the anti-offset structure 44 includes a rotating gear 441, a lifting plate 442, and a contact block 443. The lifting plate 442 is located on the side of the rotating gear 441 and is meshed. The contact block 443 is fixedly connected to the lower end of the lifting plate 442. The contact block 443 includes a block body 4431 and a matching groove 4432. The matching groove 4432 and the block body 4431 are an integrated structure.

[0029] Please refer to Figure 5, A flattening device for the production of packaging cartons. The clamping structure 45 includes a large ring opening 451, a tapered plate 452, a small ring opening 453, and a flexible plate 454. The large ring opening 451, the tapered plate 452, and the small ring opening 453 are of an integrated structure. The small ring opening 453 is located above the large ring opening 451. The rear end of the flexible plate 454 is fixedly connected to the inner wall of the tapered plate 452. The small ring opening 453, the large ring opening 451, and the shaft rod 43 penetrate through each other.

After passing the shaft rod 43 through the flattening roller 46, then penetrate the clamping structure 45 through the shaft rod 43 and place it on the left and right sides of the flattening roller 46. Due to the toughness structure of the flexible plate 454 and its annular setting, when the shaft rod 43 passes through the flexible plate 454 and passes through the center of the ring formed by it, adjust the tapered plate 452 to the side of the flattening roller 46, and the flexible plate 454 can abut against the outer circumference of the shaft rod 43, playing a role in laterally blocking the left and right displacement of the flattening roller 46 and preventing the lateral deviation of the flattening roller 46, so as to make the flattening operation proceed better.
