The attaching process of the tencel can be realized by the steps that the suction module rubs and glues the upper part of the roller in the roller glue mechanism in a tangential direction and continuously moves to the upper part of the tencel cover, and the tencel is pressed into the tencel cover for attaching. In the second embodiment described above, the crown 20a is inverted and the opening is upward during the process of manufacturing the first crown 20b. Therefore, the device of the space card attaching process can be directly added to the side of the process device, and the device can be directly put down to realize the attaching. Or, the material and the top card can be adhered directly before the top cover material 20a is formed. And after the day card is stuck, the assembly of the day cover and the inner box is continued according to the original process flow.

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 tissues and the inner box are adhered with a short stroke.

There is another device for wrapping paper on the market, a forming machine of a vertical turntable, in which a forming cavity is provided and the required mechanisms for each side of the turntable are provided on the outside of the turntable. Because of the mechanical limitations of the vertical turntable, such a box-out machine can only be adapted to smaller boxes, the box body size typically being around 90 x 70 x 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 of huge and bulkiness of the forming turntable can occur 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, wherein the box taking mechanism 952 capable of integrally moving the facial tissues and the inner box is arranged between the channel forming mechanism 955 and the transmission module 951, and the box taking mechanism 952 can be rotated and lowered. The box taking mechanism 952 comprises a rotary divider and two suction modules 953, wherein the two suction modules synchronously descend, one suction facial tissue and an inner box, and the other pressing facial tissue and the inner box enter a first stroke 71 in a channel forming mechanism 955.

More specifically, the transfer module 951 arranges the inner box and the facial tissues into two right angle blocks before moving to the outer box machine. The suction module 953 descends to suck the inner case 70, and the non-adhered portion of the outer sheet is held by sliding on the ring rail 954 while rotating. After 180 ° rotation, the first stroke 71 is entered above and lowered into the channel forming mechanism 955 to start the first stroke 71. Meanwhile, another sucking module 953 sucks the next facial 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 then the second inner box is lifted upward to form an 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 through the air cylinder to discharge materials.

The channel forming device of the embodiment has special beneficial effects on the large-size opening strip box: firstly, the floor paper is not large; and 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.
