Description

Technical Field

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

[0002] Cartons are the most widely used packaging products. Depending on the materials used, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. As an indispensable part of modern logistics, packaging cartons bear the important responsibilities of containing, protecting products, and aesthetics. During the production and processing of packaging cartons, flattening equipment is needed to flatten the cardboard.

[0003] However, in the prior art, most of the packaging carton flattening devices cannot be adjusted. When the pressing plate is small, it is necessary to manually adjust the position of the carton continuously to flatten all the cartons. Multiple operations increase the flattening time and reduce the flattening efficiency of the packaging carton flattening device. In addition, the existing packaging carton flattening device lacks a positioning structure. The carton may be displaced during the flattening process, so the position of the carton needs to be readjusted to place it in a suitable position before it can continue to be flattened. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a packaging carton flattening device, comprising: a base, a plurality of supporting legs are fixedly installed on the bottom surface of the base, two U-shaped support frames are fixedly installed on the top surface of the base, vertical grooves are opened on the inner wall surfaces on both sides of the two U-shaped support frames, vertical rods are fixedly installed between the inner walls at the upper and lower ends of the vertical grooves, slides are slidably connected on the surfaces of the vertical rods, support plates are fixedly installed between the opposite sides of the slides, cylinders are fixedly installed on the top surfaces of the two U-shaped support frames, the output ends of the two cylinders are fixedly connected to the support plates, an adjustment component is provided on the surface of the support plate, and a positioning component is provided on the top surface of the base.

[0006] As a preferred embodiment, the adjustment assembly includes two cross slides, and two sliders are slidably connected inside the two cross slides. Four sliders are grouped in pairs and are connected to flattening rollers via bearings.

[0007] As a preferred implementation, a motor frame is fixedly mounted on the top surface of the support plate, a forward and reverse motor is fixedly mounted on the top surface of the motor frame, and a rotating plate is fixedly mounted on the output end of the forward and reverse motor.

[0008] As a preferred embodiment, both sides of the top surface of the rotating plate are movably connected with hinged plates via connecting shafts, and one end of the two hinged plates is hinged to two of the sliding blocks.

[0009] As a preferred embodiment, the positioning assembly includes a groove, which is opened on the top surface of the base, and long grooves are opened on both sides of the inner wall surface of the bottom of the groove, and long rods are fixedly installed between the inner walls at both ends of the two long grooves.

[0010] As a preferred embodiment, two baffles are slidably connected between the two long rods, and two springs are fixedly installed between one side surface of the two baffles and one side inner wall surface of the two long grooves.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. The utility model, by setting an adjustment component, when it is necessary to flatten packaging cartons of different sizes, firstly, the packaging cartons to be flattened are placed inside the groove, and then two cylinders are operated by an external controller, and the operation of the two cylinders drives the support plate to move downward, and the downward movement of the support plate drives the two flattening rollers to move downward, when the two flattening rollers can flatten the carton, then the operation of the two cylinders is stopped and the forward and reverse motors are operated by the external controller, and the operation of the forward and reverse motors drives the rotating plate to rotate, and the rotation of the rotating plate drives the two hinged plates to move, and the movement of the two hinged plates drives two sliders to move in the directions away from each other inside the two cross slides, wherein the two sliders move in the directions away from each other inside the two cross slides and drive the two flattening rollers to move in the directions away from each other, and the two flattening rollers move in the directions away from each other, so as to comprehensively flatten the packaging carton, and the forward and reverse motors drive the rotating plate to rotate back and forth, and then the packaging carton is repeatedly flattened, and through the cooperation of the above structure, the distance between the two flattening rollers can be adjusted, so that packaging cartons of different sizes can be flattened, and there is no need to manually adjust the position of the packaging carton, thereby improving the flattening efficiency of the device.

[0013] 2. The utility model sets a positioning component. When it is necessary to fix the packaging carton in a suitable position, the two baffles are first pulled to make the two baffles move away from each other on the surfaces of the two long rods. The movement of the two baffles away from each other on the surfaces of the two long rods will squeeze multiple springs, thereby causing the multiple springs to be compressed. When the distance between the two baffles is sufficient to place the packaging carton, the packaging carton is placed inside the groove, and then the two baffles are released. The rebound force of the multiple springs is used to clamp and limit the packaging carton. Through the cooperation of the above structure, the two baffles cooperate with the multiple springs to position the packaging carton, avoid displacement of the packaging carton during flattening, and improve the practicality of the device.
