Description

Technical Field

[0001] The utility model relates to the technical field of flattening equipment, in particular to an automatic carton flattening device. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, they can be divided into corrugated boxes and single-layer cardboard boxes. During the processing of cartons, they usually need to be flattened, and thus a carton flattening device is needed.

[0003] In order to facilitate the flattening of cartons, the prior art has made many improvements to the automatic flattening device for cartons, such as the patent publication number CN220594223U, which discloses an automatic flattening device for cartons, including a feeding mechanism, the feeding mechanism includes a mounting plate, the two sides of the top of the mounting plate are symmetrically fixed with side plates, the top of the mounting plate is fixedly installed with a baffle on one side between the two sets of side plates, the bottom of the mounting plate is fixedly installed with four groups of connecting columns, the bottom end of the connecting column is fixedly installed with a bottom plate, the top of the connecting column is slidably installed with a moving plate, and the surface of the connecting column between the bottom plate and the moving plate is sleeved with a spring. The automatic flattening device for cartons, by setting a feeding mechanism and a guide mechanism, places the cartons on the top of the top plate, lifts the moving plate under the elastic action of the spring to drive the top plate to move up, loosens the locking screw sleeve according to the size of the cartons to adjust the distance between the two sets of moving guide plates, so that the cartons can be flattened in parallel through the flattening mechanism after passing through the two sets of moving guide plates.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] In the above-mentioned comparative document, batches of cartons are clamped between the friction wheel and the top plate by the tension of the spring, and the cartons are transferred one by one to between the two flattening rollers for flattening through the rotation of the friction wheel. However, in reality, the force of the spring is mutual. The longer the spring is stretched, the greater the clamping force of the friction wheel and the top plate on the batch of cartons. The greater the clamping force on the cartons, the greater the friction between the cartons. There may be a situation where the friction wheel cannot push the carton to the guide plate position in the above-mentioned comparative document. On the contrary, the shorter the spring is stretched, the smaller the clamping force of the friction wheel and the top plate on the batch of cartons, and the smaller the friction between the friction wheel and the carton. There may also be a situation where the friction wheel cannot push the carton to the guide plate position in the above-mentioned comparative document, and when it is necessary to add cartons, the flattening process of the carton needs to be interrupted, thereby reducing the efficiency of flattening the carton. Therefore, there is an urgent need in this field to improve the automatic carton flattening device to solve the defects of the prior art. Utility Model Content
