Description

Folding and pasting forming mechanism in the carton

technical field

The invention relates to a carton forming machine, in particular to a mechanism for inner folding and pasting of cartons.

Background technique

At present, the blank boxes used for forming cartons (such as shoe boxes, shirt boxes, gift boxes, mobile phone boxes, etc.) are first die-cut by gray cardboard, conveyed, and the four corners are pasted together, and then the blank boxes are processed. 1. The surface paper (the glued surface paper is under the base box) is positioned and glued, and then transported to the pasting forming mechanism through the extraction mechanism and the feeding mechanism for pasting to form the finished carton. Among them, the pasting forming mechanism includes the inner folding forming of the carton, the inner folding pressing, and the pasting positioning process. Small pieces of paper make the whole look uneven and unattractive, which affects the quality of carton forming. When it is required that the inner fold exceeds the middle line of the carton (especially when the full carton height face paper is folded inward), it cannot be realized due to the blocking of the slide bar above the carton.

Contents of the invention

The object of the present invention is to overcome the above-mentioned disadvantages, and provide a carton inner-folding and pasting forming mechanism for the inner-folding of the carton to be full-height face paper.

The purpose of the present invention is achieved through the following technical solutions: the folding and pasting forming mechanism in the carton includes a device for pressing the folding in the carton, a device for forming the folding inside the carton, and a positioning device for the paper and the paper box. The slide bar of the edge pressing device is equipped with a mold through the end block of the slide bar, and a cylinder for ejecting paper is installed on the end block of the slide bar and inside the mold; A wooden mold is housed on the knife and the lower movable rod; a spring assembly is housed in the supporting cylinder of the paper box positioning device, and the spring assembly and the cylinder shaft of the one-way cylinder abut against each other laterally.

After adopting the structure of the present invention, when the face paper on the four sides is folded inward by the jackknife to the semi-finished carton to the height of the carton, the top paper cylinder starts to pre-press the inner fold paper downwards, and the cylinder shaft and the wooden mold are aligned. The carton is positioned. Immediately afterwards, the slide bar is pressed down, the paper jacking cylinder is retracted, and the mold is pressed to the inner side and inner bottom of the semi-finished carton to flatten the folded full carton height face paper. In this way, the inner folding of the carton is completed, and the folding, flattening, and forming actions of the full carton height are completed, making the overall look smooth and beautiful, thereby improving the quality of carton forming.

Detailed ways

Referring to Fig. 1, it can be seen that the present invention is applied to the carton inner folding paper forming mechanism of the carton forming machine, including the carton inner folding pressing device 21, the carton inner folding forming device 22, and the carton paper positioning device 23, The slide bar 2 of the inner folding press-in device 21 of the carton is equipped with a mold 4 through a slide bar end block 19, and a top paper cylinder 3 is housed on the slide bar end block 19 and in the mold 4; Folding knife 5 is housed on the upper movable rod 17 of box internal flanging forming device 22, and wooden mold 6 is housed on the lower movable rod 18; It abuts laterally with the cylinder shaft 10 of the one-way cylinder 11.

Wherein, the slide bar 2 of the folded edge pressing device 21 in the carton is installed on the slide bar seat 1, and the top paper cylinder 3 has included the top cardboard, and the upper part of the top paper cylinder 3 is on the slide bar end block 19, and the top paper cylinder 3 is placed on the slide bar end block 19. The bottom of cylinder 3 is in mold 4; Parts such as described slide bar seat 1, slide bar 2, slide bar end piece 19, mold 4, top paper cylinder 3 constitute hemming press-in device 21 in the carton. The upper movable rod 17 and the lower movable rod 18 of the folding forming device 22 in the carton are mounted on the work seat 12, and the upper movable rod 17 and the lower movable rod 18 are controlled by respective control components to move left and right; Parts such as described work seat 12, upper movable bar 17, jackknife 5, lower movable bar 18, wood mold 6 constitute hemming forming device 22 in the carton. The one-way cylinder 11 of carton pasting positioning device 23 is contained on the guide rail 15, and supporting plate 8 is housed on the top of cylinder shaft 10, is used for laying blank box 20 (bonded with face paper); Consists of parts such as cylinder 11 (comprising cylinder shaft 10), guide rail 15, supporting plate 8, spring assembly 16 and paper box paper positioning device 23. The spring assembly 16 is composed of a spring seat 9, a limit spring 13 installed in the spring seat 9, a spring top 7 installed in the spring seat 9 and facing the limit spring, and the spring seat 9 is connected to the cylinder shaft 10 side. To the top.

The working principle of the present invention is: at first, the slide bar 2 of the folding edge pressing device 21 in the carton drives the slide bar end block 19, the top paper cylinder 3, the mold 4 to move downwards and the carton semi-finished product (has been stuck with facial tissue) ) to the folding station of the carton forming, between the folding knife 5 and the wood mold 6 of the folding forming device 22 in the carton, the supporting plate 8 on the top of the cylinder shaft 10 of the carton pasting positioning device 23 is close to the The bottom of the carton blank moves down here. Then, the slide bar rises, and the mold and the top paper cylinder are pulled away from the semi-finished carton formed by bonding the base box and the face paper. The folding knife 5 and wooden mold 6 of the hemming forming device 22 in the carton carry out the inner and outer hemming process of the face paper to the blank box, and the wooden mold is close to the outside of the paper box.

When the four sides of the paper are folded inwards at the full carton height to the semi-finished carton, the top paper cylinder receives a signal to start, stretches out the cylinder head, and pushes the top paper board downward to pre-press the paper The origami and jackknife in the box will be returned. Immediately afterwards, the slide bar is pressed down, and as the slide bar is pressed down, the paper ejector cylinder is retracted, and the mold is pressed to the inner side and inner bottom of the semi-finished carton, and the folded inward full carton height surface The paper is flattened, and the wooden mold is pressed tightly against the outside of the carton. Then the slider goes up. In this way, the inner origami of the carton is folded and flattened by the full carton height of the paper box, and the inner fold is made of a full paper carton (as shown in Figure 2).

Simultaneously, when the slide bar presses down the supporting plate 8 of the carton pasting positioning device 23 and the blank box face paper on it, it moves down to the place between the jackknife 5 and the wooden mold 6 of the hemming forming device 22 in the carton. Finally, the support tube 14 pushes the spring seat 9 to move the spring assembly 16 to the inside (that is, to the side of the cylinder shaft 10), and just clamps the spring assembly on the cylinder shaft to lock the cylinder shaft in this position, so that the cylinder shaft The blank box face paper on the top pallet completes the outside and inside folding and pasting process, and completes the full carton height face paper type inner folding of the carton (the finished carton is shown in Figure 2). After finishing the outer and inner folding and pasting actions of the whole blank box face paper, the limit spring 13 begins to return, and because the spring top 7 is fixed, so the spring seat is promoted to unclamp the locking of the cylinder shaft. At this time, the pallet and the finished carton on it can be pushed by the cylinder shaft of the one-way cylinder and rise with the slide bar.

This is especially applicable to the carton packaging of Apple brand mobile phones. Comparing Figure 2 and Figure 3, we can see that the overall appearance and workmanship of the carton with the full carton height surface paper folded inward (also called the full paper height) is different from the ordinary carton by comparing the two. Of course, it is also possible to complete the facial paper folded halfway through the middle line of the carton.
