Device and method for accurate positioning of facial tissue and inner box of packing box

Abstract

The invention provides a device and a method for accurate positioning of a facial tissue and an inner box of a packing box. The device comprises a box falling mechanism (10), a CCD assembly (20), a conveyer belt (30) and a conveyer belt mounting frame (40), wherein the box falling mechanism (10) is used for completing the box falling operation, the CCD assembly (20) is used for detecting the state of the facial tissue and transferring information, the conveyer belt (30) is used for transferring the facial tissue and adjusting the excursion of the facial tissue relative to the X direction and the Y direction of the inner box, and the angular deviation of the facial tissue and the Z direction of the inner box can be eliminated by controlling the rotation of the conveyer belt mounting frame (40); the box falling mechanism (10) comprises a box falling power unit (11), a box falling sliding rail (13), an inner mold (14) and a connecting block (15), a motor in the box falling power unit (11) drives a screw rod to rotate, and the power is transferred to the box falling sliding rail (13) by the connecting block (15), so that the box falling operation is realized. According to the invention, the inner box is fixed, but the facial tissue moves in the alignment process of the inner box and the facial tissue, so that not only is the adhesion precision of the facial tissue and the inner box improved, but also the stability and the reliability of the positioning operation can be improved.

Description

technical field [0001] The invention relates to the technical field of packaging box production, and more specifically relates to a precise positioning device and method for a face paper and an inner box during the forming process of a high-quality packaging box. Background technique [0002] With the continuous development and progress of the market economy and the continuous improvement of people's living standards, the packaging requirements for commodities are also increasing, especially in the fields of consumer electronics, decorations and luxury goods such as mobile phone boxes, gift boxes, jewelry boxes, wine boxes, etc. Boxes, etc., high-quality packaging suitable for high-quality products is essential. The processing and molding process of high-quality packaging boxes is generally formed by wrapping the inner box with tissue paper. The tissue paper is the outer decorative material, and the inner box is a hard cardboard support structure, and the two are glued toget...

AI Technical Summary

Problems solved by technology

The existing technology will have the following problems, making it difficult to further improve the positioning accuracy:

[0004] (1) The inner box is transported to the designated position by the conveyor belt, and it is positioned by the reference based on mutual extrusion, the preformed state of the box body, the cutting state of the gray board, and the stability of the extrusion state, etc., will cause the inner box to be pressed down before pressing It is difficult to improve the positioning accuracy;

[0005] (2) The detection device is installed on the alignment moving parts, and the structure shakes a lot, which reduces the positioning accuracy and makes the product quality unable to be guaranteed stably;

[0006] (3) The process of inner box falling is realized by means of lever amplifying the stroke, which will cause the instantaneous impact force of the inner box on the face paper to be too large, which will cause the position of the box body or face paper to shift, which will also reduce the positioning accuracy and deteriorate the product quality. no guarantee of stability

[0007] Invention patent publication CN101214739A "Blank box surface paper positioning and bonding mechanism of Tiandi cover carton forming machine" adopts the traditional positioning machine positioning method, which has the defects of low positioning accuracy and insufficient structural stability
