As shown in fig. 10, the vertical sealing module 333 includes a second supporting member 3331 and a vertical sealing assembly 3332 disposed on the first supporting member 3331, wherein the vertical sealing assembly 3332 includes a second heating member and at least two heat sealing strips 3334 disposed on a surface of the second heating member 3333 and opposite to each other.

It should be noted that, in this embodiment, the position adjusting structure of the horizontal sealing wheel 3323 and the adjusting structure and manner of the heat sealing strip 3334 are not limited, and any structure capable of achieving position adjustment is applicable to this embodiment, and may be implemented by adjusting screws, sliding rails, and the like.

Preferably, the slitting module 334 comprises a slitting driving knife (not shown), a driven rotary knife (not shown) and an adjustable fixing base (not shown). Wherein, the passive rotary cutter is fixed on the adjustable fixing seat, so that the center is adjustable. The cutting driving knife can drive the driven rotary cutter, and the cutting driving knife is made of high-hardness materials, so that abrasion of the driven rotary cutter to the cutting driving knife due to high force can be reduced.

Of course, the packaging mechanism 330 further includes a plurality of pulling members, deviation correcting members, etc. to improve the slitting accuracy.

In conclusion, the multi-column production packaging equipment provided by the embodiment effectively improves the production universality by optimizing the specific structures of the raw material feeding device, the production device and the packaging device on the premise of ensuring continuous production so as to meet the production requirements of products with different sizes.

Example 2

As shown in fig. 1 and 11, the present embodiment provides a wet towel production apparatus which is further optimized to be formed for the production of wet towels on the basis of the multi-line type production packaging apparatus described in embodiment 1.

Compared with the multi-row type production packaging equipment in the embodiment 1, the wet tissue production equipment has the following differences: the production apparatus 200 further includes a filling mechanism 280, and the filling mechanism 280 is disposed downstream of the vertical folding mechanism 230.

Specifically, the filling mechanism 280 includes a liquid delivery module (not shown) and at least two filling members 281 disposed side by side for filling the third semi-finished product.

In one embodiment, the speed of the liquid adding member 281 is constant, and the liquid adding amount of the third semi-finished product is controlled by controlling the liquid adding speed so as to meet different liquid adding requirements.

Of course, in order to meet the requirement of sterility in the process of producing wet wipes, the wet wipe production apparatus further comprises a housing (not shown) for accommodating the raw material feeding device 100, the production device 200 and the packaging device 300.

Similar to the previous embodiment, the wet tissue production equipment provided by the embodiment effectively improves the production universality by optimizing the specific structures of the raw material feeding device, the production device and the packaging device on the premise of ensuring continuous production so as to meet the production requirements of products with different sizes;

and the liquid adding mechanism is arranged to meet different liquid adding quantity requirements, so that the product universality is further improved.

All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present invention, that is, any multiple embodiments may be combined to meet the requirements of different application scenarios, which are within the protection scope of the present application and are not described herein again.

It should be understood that the above-mentioned embodiments are merely preferred embodiments of the present invention, and not intended to limit the present invention, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
