Example six:

as shown in fig. 9, the present invention also provides an outer box machine which can simultaneously implement an over-molding process after the facial tissue and the inner box are adhered with a short stroke.

The market also has another equipment capable of realizing the coating of the external facial tissue, namely a forming machine of a vertical turntable, wherein a forming cavity is arranged in the turntable, and a mechanism required by the edge shoveling of each surface is arranged outside the turntable. Because of the limitations of the vertical turntable mechanism, this external box machine can only be applied to smaller boxes, and the size of the box body is usually about 90 × 70 × 15 mm. The size of the box body of the open strip box is about 300 multiplied by 80 multiplied by 60 mm, and the defect that the forming turntable is large and bulky when the vertical turntable forming machine is used for wrapping the outer paper of the large-size inner box.

Referring to fig. 7, the outer box machine includes a channel forming mechanism 955 and a box taking mechanism 952, the box taking mechanism 952 capable of moving the facial tissue and the inner box integrally is disposed between the channel forming mechanism 955 and the transfer module 951, and the box taking mechanism 952 can rotate and descend. The cassette picking mechanism 952 includes a rotary cutter and two suction modules 953, which descend synchronously, one of which sucks the facial tissue and the inner cassette, and the other of which pushes the facial tissue and the inner cassette down into the first stroke 71 of the channel forming mechanism 955.

More specifically, the transport module 951 moves the inner box and the facial tissue together to the outer box machine, and then arranges the postures through the two right-angle blocks. The suction module 953 descends to suck the inner box 70, and the part of the outer surface paper which is not adhered slides on the ring rail 954 while rotating, so that the surface paper is kept in shape. After rotating 180 °, the rod enters above the first stroke 71, descends into the channel former 955 and begins to travel the first stroke 71. Meanwhile, another suction module 953 sucks the next tissue and inner box material on the conveying module.

At the end of the first stroke 71 in the channel forming mechanism 955, a first inner box 70a is formed, then a second inner box 70b is formed through a second stroke 72, and the second inner box is lifted upwardly to form the outer box 80. The outer boxes 80 are continuously stacked in the channel where the third stroke 73 is located, and the outer box 80 at the highest layer is pushed out by the air cylinder to be discharged.

The channel forming device of the embodiment has a special beneficial effect on the large-size opening strip box: firstly, the occupied area of the surface paper is not large; compared with the old forming process, the forming step reduces the steps of pre-forming and transferring the inner box and the facial tissue and the corresponding mechanisms, and the forming efficiency is higher.
