AI Technical Summary
Traditional V-slot boxes cannot achieve low-cost mass production. The coating is easy to fall off when pressed by the automatic sticker machine. The V-slot processing accuracy is insufficient and the sticking edges cannot be aligned, resulting in poor aesthetics and inability to fold and transport.
The jumping V-slot equipment is used to combine multi-angle V-slots and automatic box stickers with automatic bias correction function to achieve arbitrary V-slot processing and precise alignment of edges. A V-slot structure greater than or equal to 90 degrees is used, and combined with innovative tool line structure and correcting guide rail adjustments ensure that the adhesive edges are aligned with the folded line without gaps.
The V-slot box is realized with low-cost mass production, with the sticky edges aligned with the folded lines, and the box can be folded and transported to avoid the coating falling off, improving production efficiency and product quality.

Abstract
Description
Technical Field
[0001] The present invention relates to a perfect high-precision V-groove box technology, and this box is applied to the low-cost automated mass production of non-top-and-bottom cover boxes or top-and-bottom cover boxes (applied in industries such as gifts, mobile phones, express packaging, jewelry, ornaments, cosmetics, clothing, shoes, glasses, food, health products, pharmaceuticals, household products, home decoration, leather goods, stationery, computers, digital products, household appliances, speakers, etc.). Background Art
[0002] 1. Traditional V-groove boxes are generally used for top-and-bottom cover gift boxes, wine boxes, mobile phone boxes, etc. These boxes have relatively thick walls (generally the wall thickness is greater than 1 mm). Generally, they are made by pasting a piece of face paper on the surface of an internal hard cardboard by hand, with complex processes and high costs. They cannot be mass-produced on a large scale at low cost, and such boxes cannot be folded for transportation, resulting in relatively high logistics costs.
[0003] 2. Traditional non-top-and-bottom cover boxes (boxes with snap positions) basically do not use V-grooves. Even if they do, it is difficult to mass-produce them on a large scale because most of the V-groove boxes made are 90-degree V-grooves, which can only be pasted by hand and cannot be mass-produced, resulting in high costs.
[0004] 3. There is a fatal problem with all 90-degree V-grooves. That is, when using an automatic box pasting machine, after the box pasting is completed, the automatic box pasting machine generally needs to flatten the pasted boxes together for packing and transportation. As shown in Attachment Figure 1 a, the film on the surface of the box will burst due to the large stress at the 90-degree folding edge, resulting in glue and film detachment, and it cannot be flattened smoothly. After strong flattening, the box shown in Attachment Figure 1 b is obtained. ① is the wrinkle generated by the detachment of the surface film, and it cannot be used at all, and all the boxes are scrapped.
[0005] 4. Traditional V-groove machines cannot achieve precise jumping V-grooves. They can only V from one end to the other end, and cannot jump and change the trajectory in the middle, which will V all the places that should not be V-ed. As shown in Attachment Figure 3 a's ②, which causes the left and right sides to be cut off without reason, affecting the beauty of the box. It will also cause ③ to be a straight line and cannot be folded into a box because a normal box must be a high-low line structure. As shown in Attachment Figure 3 b, ① and ④ are at different heights, and the greater the thickness of the paper, the greater the height difference between ① and ④.
[0006] 5. Traditional automatic box pasting machines cannot adjust the position of the pasted edge. The box pasted out is the same as the die-cutting template, and it is impossible to align the pasted edge. As shown in Attachment Figure 4 b's style, only the box shown in Attachment Figure 4 a can be obtained, and there are gaps at the pasted edge and it cannot be aligned with the crease line of the box. Summary of the Invention
[0007] In order to enable the V-groove box to be mass-produced at low cost, the present invention adopts an innovative jumping V-groove device. Through digital control technology, V-groove processing can be carried out at any position on the paper. Combining multiple-angle V-groove combinations can achieve smooth feeding into an automatic box gluer. Moreover, an automatic box gluer with an automatic deviation correction function is adopted, which can make the stress at the folded edge of the box small when the box is flattened, and can align the glued edge position with the box folding line, enabling the V-groove box to be mass-produced in large quantities. Whether it is a paper box, a plastic box, a fiber box, a metal box or a non-metal box, a glass box, large-scale mass production can be achieved.
[0008] Technical solution:
[0009] By combining an innovative jumping V-groove device with two types of angle V-grooves and using an automatic box gluer with an automatic deviation correction function for box gluing, the line parallel to the glued edge of the box uses a V-groove greater than 90 degrees and less than 180 degrees, and other sides such as the insert tongue, the flap, the top cover, and the bottom cover use V-grooves greater than or equal to 90 degrees, and the automatic box gluing problem can be successfully solved. Whether it is a hexahedron box, an octahedron box, a decahedron box, a dodecahedron box, a box with more faces or a lidless box, low-cost mass production can be achieved.
