Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting equipment, in particular to a flattening and die-cutting device for carton production. Background Art

[0002] Carton die-cutting machine is a machine used for die-cutting cardboard in carton forming process. It is generally divided into two types of die-cutting: flat-to-flat and round-to-round. The die-cutting process can make printed materials or other paper products into die-cutting plates according to pre-designed graphics for cutting, so that the shape of printed materials is no longer limited to straight edges and right angles. With the development of packaging machinery, food packaging, gift packaging, and wine packaging are becoming more and more important. The shapes of packaging boxes are different and each has its own characteristics. Carton die-cutting machines are widely used as product packaging machinery.

[0003] The die-cutting of cartons is mainly for cutting the processed cartons. Since the cartons are made of corrugated board, the surface is prone to unevenness, and some areas of the carton are excessively twisted, which causes the roller to be unable to flatten, resulting in the machine being stuck and affecting subsequent die-cutting work. For this reason, we propose a carton production flattening die-cutting device. Utility Model Content

[0009] Preferably, the pretreatment mechanism further comprises a bracket, the bracket is fixedly connected to the bottom of the telescopic rod, and a first pressing roller and a second pressing roller are sequentially arranged inside the bracket.

[0010] Preferably, the flattening mechanism comprises a flattening roller, and rotating shafts are arranged on both sides of the flattening roller, and the rotating shafts are rotatably connected to the inside of the support frame.

[0011] Preferably, the limiting rod and the supporting rod are symmetrically arranged with respect to the conveyor belt, the height of the limiting rod is equal to the height of the supporting rod, a groove body corresponding to the fixed shell is opened inside the supporting rod, and the fixed shell can slide inside the groove body.

[0012] Preferably, the width of the fixed shell is smaller than the width of the slider, and a groove corresponding to the screw rod is provided inside the slider, so that the slider can play a role in limiting the position of the fixed shell.

[0013] Preferably, the first pressing roller and the second pressing roller are both rotatably connected to the inside of the bracket via a rotating shaft, the height of the plane where the bottom of the first pressing roller is located is higher than the height of the plane where the bottom of the second pressing roller is located, and the first pressing roller can pre-press the bend of the carton, and then use the second pressing roller to flatten it.

[0014] Beneficial effects:

[0015] 1. The carton production flattening die-cutting device detects the carton on the top of the conveyor belt through a detection mechanism. If there is a carton bending problem, the pretreatment mechanism is controlled to pretreatment the bending area, that is, under the action of the infrared sensor, it detects whether there is a bulge on the surface of the carton, and then the first pressing roller and the second pressing roller are driven by the telescopic rod to press down. The height and structure size of the first pressing roller are greater than those of the second pressing roller, so that the first pressing roller can press down the bent carton to reduce its bending degree, and then the second pressing roller performs a flattening operation to facilitate the subsequent flattening of the carton and avoid the problem of machine jamming.

[0016] 2. The carton production flattening die-cutting device can drive the lead screw to rotate inside the slide rail by turning the knob, so as to drive the slider to move, and then drive the fixed shell to drive the infrared sensor to move, so as to complete the adjustment of the infrared sensor position and scan cartons of different specifications, thereby increasing the universality of the device. The length of the telescopic rod can be controlled to match the carton bending problem detected by the infrared sensor, and the structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
