Description

Technical Field

[0001] The utility model relates to the technical field of carton machines, in particular to a transverse slotting component of a carton machine. Background Art

[0002] Cartons are the most widely used packaging products, usually used as wrapping materials for commodities or as outer protective layers for articles. Cartons are formed by bending cardboard during production, and in order to make the carton completely closed, a number of grooves need to be opened at the upper and lower ends of the cardboard to facilitate folding the cardboard to close the carton. The structure for slotting the cardboard is a slotting assembly, which usually consists of an upper knife shaft and a roller. A slotting knife is provided on the upper knife shaft, and the cardboard is slotted by rolling the upper knife shaft. However, cartons of different models or sizes on the market currently require slots of different lengths, so the upper knife shaft with slotting knives of different lengths needs to be replaced, which is very inconvenient and makes the work efficiency very low.

[0019] 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 belong to the scope of protection of the utility model.

[0020] The utility model provides a transverse slotting component for a carton machine, comprising a roller 1 and a knife shaft 2 located above the roller 1. There is at least one knife shaft 2, and two knife shafts 2 are usually provided. The two knife shafts 2 are respectively arranged close to two ends of the roller 1. The knife shaft 2 and the roller 1 are coaxially arranged. A slotting knife 3 is axially arranged on the outer periphery of the knife shaft 2. Cardboard is transmitted between the knife shaft 2 and the roller 1. The slotting knife 3 slots the cardboard as the knife shaft 2 rotates. The two knife shafts 2 are combined by belts, gears and rotating shafts to realize synchronous rotation. The outer wall surface of the roller 1 is made of elastic material, such as a soft rubber pad, so that the slotting knife 3 of the knife shaft 2 will not cut the surface of the roller 1 when slotting, and will not cause damage to the slotting knife 3 itself, and can also stably convey the cardboard, or the roller 1 is a rubber roller.

[0021] In this embodiment, the roller 1 is a long roller with a relatively long length, and the blade shaft 2 is an axial roller with a relatively small length. The length ratio of the blade shaft 2 to the roller 1 is 1:4.

[0022] There is a bracket above the knife shaft 2, which serves as the supporting structure of the entire assembly. The roller 1, slide rail 5 and screw pair 7 are all directly connected to the bracket, and the knife shaft 2 is indirectly connected to the bracket through a transmission structure. The specific form is not repeated here. The bracket is provided with a slide rail 5 along the axial direction of the roller 1, and a slider 6 is slidably matched on the slide rail 5. The bracket is also provided with a screw pair 7. The screw in the screw pair 7 is arranged along the slide rail 5, and the nut in the screw pair 7 is connected to the slider 6, so that the slider 6 can reciprocate along the slide rail 5 under the drive of the screw pair 7. The knife shaft 2 is rotatably connected to the slider 6 and reciprocates with the slider 6, so that the two knife shafts 2 can reciprocate relative to each other. In this embodiment, there is only one slide rail 5 and one screw pair 7, and the two sliders 6 are slidably matched to the same slide rail 5 and screw pair 7. The screw in the screw pair 7 is a left-right rotating screw, so that the two knife shafts 2 can move relative to or oppositely with the corresponding slider 6.

[0023] In another embodiment, there are two slide rails 5, and correspondingly, there are two sliders 6 and two lead screw pairs 7, which are arranged one by one with the two knife shafts 2. The two slide rails 5 are arranged coaxially and side by side on the bracket, and the lead screws in the lead screw pair 7 are also arranged coaxially and side by side. Since there are two lead screw pairs 7, the two slide rails 6 correspond to the lead screw pair 7 separately, so the lead screw in the lead screw pair 7 can be a common single-head lead screw, so that the two slide rails 6 can be controlled separately by the corresponding slide rails 5 and lead screw pair 7, so that the two knife shafts 2 can be translated at the same time or moved separately, which is very flexible. In addition, the driving devices for driving the lead screw, knife shaft 2 and roller 1 to rotate are all conventional belt gear transmission structures, which will not be repeated here.

[0024] The lead screw pair can also be replaced by other mechanical transmission structures, such as a gear-rack transmission method, a slide-rail transmission method, etc., which will not be elaborated here.

[0025] An axial groove is provided on the surface of the cutter shaft 2, and positioning holes are provided at both ends of the groove. The groove cutter 3 is embedded in the groove and fixed by the positioning holes. It should be noted that the groove cutter 3 includes a base 31 and a blade 32 located on the base 31. The base 31 is a plate-like structure and one side is an inwardly concave arc surface adapted to the arc circumference of the cutter shaft 2. The blade 32 is installed on the other side of the base 31. The base 31 is installed in the groove and forms a limit. The base 31 is provided with mounting holes on both sides of the blade 32. Fasteners are installed in the mounting holes to realize the installation of the groove cutter 3 on the groove, thereby realizing the detachable connection of the groove cutter 3 to the cutter shaft 2.

[0026] In this embodiment, there are multiple grooves, which are distributed in a circular array along the outer circumference of the knife shaft 2. The groove cutters 3 are arranged one by one corresponding to the grooves, that is, there are multiple groove cutters 3, which are evenly distributed on the circumferential surface of the knife shaft 2. When the knife shaft 2 rolls, evenly spaced grooves can be opened on the cardboard.

[0027] The blade 32 is a long strip structure, and its blade path can be a U-shape with one end open, or a rectangle with one end open, or a straight strip, etc.

[0028] The knife shaft 2 is rotatably connected to the bracket through a belt gear transmission structure, and is driven to rotate by a driving device, so that the two knife shafts 2 rotate synchronously.

[0029] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
