[0011] A production process for diapers, comprising the following steps:

[0012] Step 1: fluff forming and pulp board preparation, that is, various raw materials used for diaper filling core materials are transported to the grinder by wet feeding to be crushed and mixed evenly; then the grinder discharges the crushed materials into the roller pressing equipment for compaction process, and the powder of the mixed materials is repeatedly rolled into a filling pulp board; the repeated rolling operation of the mixed material powder in this step is mainly to roll the fluffy material powder densely, enhance the water absorption of the core body, and avoid leakage;

[0013] Step 2, laminating the filling pulp board, the filling pulp board produced in step 1 is transported to the laminating equipment by means of a crawler conveyor for laminating and rolling, and pressed into a water-absorbing core board; wherein the outer laminating film of the filling pulp board includes an upper film and a bottom film, and the upper film and the bottom film are synchronously transported to the laminating equipment with the filling pulp board; before laminating, the contact surfaces of the upper film and the bottom film with the filling pulp board are pre-coated with adhesive; in actual operation, the laminating equipment is equipped with two sets of unwinding rollers and an adhesive coating device at the material input end, and cooperates with the laminating equipment to perform laminating and rolling work; wherein the laminating and rolling can, on the one hand, further compact the core body, and on the other hand, can make the water-absorbing core board fit with the upper film and the bottom film at the same time;

[0014] Step 3: Cutting and dividing the water-absorbent core board. The water-absorbent core board in step 2 is further conveyed to the clamping and pressing device through the crawler conveyor. Before the water-absorbent core board enters the clamping and pressing device, the water-absorbent core board is cut and cut into water-absorbent core bodies of equal size and uniformity by a roller cutter with a mold. According to the actual working situation, the roller cutter is also arranged at the material input end of the clamping and pressing device and cooperates with the clamping and pressing device to work.

[0015] Step 4: Folding of the absorbent core and product forming. The absorbent core in step 3 is folded in half through a 90° turning belt and a sponge compacting belt in turn, and the waist seam of the finished product is cut out by a waist cutter during the conveying process. Then, a waist non-woven fabric and a waist rubber band are added to the waist seam to perform waist seam work.

[0016] Preferably, the raw materials of the diaper filling core material include pulp, fluff, plant fiber and high molecular water-absorbing resin; the rolling equipment in step one, the coating equipment in step two and the clamping and pressing equipment in step three are compensating hammer presses of the diaper production line, and their structures and working principles are the same, and independent auxiliary equipment is installed when each device is actually working; several of the compensating hammer presses are connected by a crawler conveyor; according to actual work needs, in this diaper production process, multiple groups of compensating hammer presses are respectively coordinated with each auxiliary equipment to achieve different functions, and the production line assembly structure is simple and easy to replace and maintain; the auxiliary equipment includes any one of the unwinding rollers for the upper film and the bottom film, a 90° steering belt, a sponge compacting belt, a waist cutter, and a rolling cutter, and the specific application is combined with the actual process requirements.

[0017] It should be added that, in the aforementioned structure, the specific modification scheme of the cylinder structure includes but is not limited to pneumatic dust removal and pneumatic glue spraying; wherein, in the case of pneumatic dust removal, it is mainly aimed at the fluff forming and pulp board preparation in the first step of the production process, and can spray air into the inside of the working box when cooperating with the roller hammer to reciprocate and press the raw materials, and use air pressure to control the diffusion direction of the internal dust to avoid dust splashing; in the case of pneumatic glue spraying, the output end of the slave cylinder is located above the unwinding rollers of the upper film and the bottom film, and the slave cylinder should also be connected and communicated with the storage box of the adhesive. During the reciprocating exhaust process, the adhesive is sprayed onto the surface of the upper film and the bottom film at the same time, so as to realize the synchronization of glue spraying and unwinding.

[0018] The present invention has the following beneficial effects:

[0019] Since the processes of pressing the pulp board, coating the pulp board, pressing the absorbent core board, and folding the pulp board in the production line of diapers all require roller pressing operations, the present invention introduces a compensating hammer press into the original production line. The compensating hammer press is an independent device that can be flexibly applied to the above-mentioned processes in the production process mainly based on the roller pressing process. It can be adjusted and installed according to the actual production and processing needs, and other different processing components can be added before and after the process of the material entering the equipment to realize different functions.

[0020] Among them, for the preparation process of the pulp board, the compensating hammer press in the present invention can complete the compacting and compacting work of the pulp board by itself, that is, by arranging a storage cavity and a driving cavity inside the slidable roller hammer, the roller pressing wheel is used to hammer up and down to fill the core plate while driving the hydraulic transmission structure inside the general equipment to work, and driving the rod pressing hammers on both sides of the working box to compensate the roller pressing wheel, which can make the fluff forming and subsequent compacting processes more complete and improve the product quality; at the same time, the compensating hammer press can, through the cylinder structure arranged inside it, spray air into the working box when cooperating with the roller pressing hammer to reciprocate and hammer the raw materials in the fluff forming and pulp board preparation processes, and use air pressure to control the diffusion direction of internal dust to avoid dust splashing;

[0021] On the other hand, for the coating work of the filling pulp board, when the compensating hammer press of the present invention is actually working, the output end of the driven cylinder is installed above the unwinding rollers of the upper film and the bottom film, and the adhesive is sprayed onto the surface of the upper film and the bottom film at the same time, so as to realize the synchronization of spraying and unwinding; and for other processes of the diaper production process, such as folding of the filling core plate and cutting and forming of the waistline, it is only necessary to add corresponding 90° turning belts, waistline cutters, roller cutting cutters, etc. at the feeding end of the compensating hammer press to complete them. Therefore, the improvement of the existing diaper production process by the compensating hammer press of the present invention is more reflected in the flexible adjustment of the working equipment, and the various processes of the production line can be adjusted at any time according to actual needs to improve work efficiency and broaden the improvement direction of the production line.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
