The wrapping device 600 includes at least one wrapping mechanism and wrapping rollers, where one wrapping roller corresponds to one wrapping mechanism, and the wrapping mechanisms are arranged according to the order of wrapping actions. In this embodiment, two coating mechanisms and two coating press rollers are provided. The two coating mechanisms are respectively a first coating mechanism 601 and a second coating mechanism 603; the two coating press rollers are respectively a first coating press roller 602 and a second coating press roller 604, and the first coating mechanism 601 is located at the rear-stage process position of the composite device 500; the first wrapping pressing roller 602 is arranged above the first wrapping mechanism 601; the wrapping material 1700 includes two side edges parallel to its conveying direction; one side edge of the packaging material 1700 is folded upwards to the middle position of the packaging material 1700 through the first wrapping mechanism 601; the second coating mechanism 603 is located at the post-stage process position of the first coating mechanism 601; the second coating pressing roller 604 is arranged above the second coating mechanism 603; the other side edge of the packaging material 1700 is folded upwards to the middle position of the packaging material 1700 through the second coating mechanism 603; the two side edges are bonded through a composite glue layer. The first and second wrapping press rollers 602 and 604 provide a widthwise folding point for the wrapping material 1700 to be folded upward. The coating process is shown in detail in figure 3. The width folding point created by the first wrapping pressure roller 602 and the second wrapping pressure roller 604 is determined by the dimension of the final packet product in the width direction. In practical applications, a third wrapping mechanism and a third wrapping roller may be provided when the length of the sanitary product 1800 is too long.

The system for manufacturing multi-packet hygienic products of the present invention further includes a counter sensor 605 located above the coating mechanism performing the last coating operation and at a position where the coating mechanism does not complete the coating operation. In this embodiment, the counting sensor 605 is located above the second wrapping mechanism 603 and at a position before the second wrapping is not completed, and the counting sensor 605 is provided to accurately count the hygienic articles 1800 without error, and provide a precondition for the subsequent pull-off press roller device 1200 to start the speed change. Since the hygienic device 1800 is completely wrapped into the wrapping material unit 1701 after the second wrapping mechanism 603 is located, the counting sensor 605 is arranged in a pair-shooting type, it is difficult to accurately count the number of the hygienic devices 1800 in the small package by thickness (if the wrapping material 1700 is thick, the counting sensor 605 has more counting errors), and the process control of the later stage is affected. In this embodiment, the counter sensor 605 is a reflection-type photoelectric sensor, and is placed above the second wrapping mechanism 603 and at a position before the completion of the second wrapping to detect the sanitary product 1800 that has not yet been fully wrapped. If the counting sensor 605 is placed above the first wrapping mechanism 601 or at an upstream position before the first wrapping mechanism 601, when the sanitary product 1800 is actually running at a high speed, the sanitary product 1800 may fall off after being counted and detected by the counting sensor 605 because the sanitary product 1800 is not adhered by the sanitary product fixing glue 401, and an empty bag is generated, so that counting errors occur because the counting sensor 605 is arranged in front and the sanitary product 1800 falls behind, and defective products with wrong counting can be taken as good products and discharged from a good product discharge port, thereby reducing the performance of the equipment and affecting the quality of the products. However, if the counting sensor 605 is placed at a position above the second wrapping mechanism 603 before the second wrapping is not completed, the hygienic device 1800 is already wrapped in the wrapping material 1700 by half under the wrapping of the first wrapping mechanism 601, ensuring that the hygienic device 1800 does not fall off because of no sticking when the second wrapping is performed, and the counting sensor 605 can directly detect the hygienic device 1800 before the second wrapping is not completed, which can ensure the counting accuracy of the counting sensor 605 by one hundred percent.

The packaging material unit 1701 in a continuous state after the completion of the wrapping by the wrapping device 600 is fed into the heat sealing device 700 by the conveyance of the upper and lower nip devices. As shown in fig. 5 and 6, heat-sealing device 700 is configured to form heat seal 1705 between two adjacent packaging material units 1701, and packaging material unit 1701 between two adjacent heat seal bars 1705 is packaging unit 1702.

The embossing pattern of the embossing module 705 can be flexibly changed while ensuring the heat-sealing strength. The heat-seal device 700 heat-seal embosses the wrapping material units 1701 in phase with respect to the packet size, so as to form the wrapping units 1702 in an individual but still continuous state, with a heat-seal bar 1705 being formed between each adjacent wrapping unit 1702, the heat-seal pattern of said heat-seal bar 1705 corresponding to the pattern of the embossing module 705.

Then, the packaging material 1700 is fed by the upper and lower second belt clamping devices 800 into a station where the pre-cutting device 900 is located, and the station is to equally divide the packaging units 1702 with continuous front ends and heat-seal embossing according to the phase position within the range of the heat-seal embossing, and the phase position of the device is consistent with the phase position of the heat-seal device 700, so as to provide a precondition for the subsequent packet stretch-breaking. For the stability of the conveying, the two upper and lower second belt clamping devices 800 in front of the pre-cutting device 900 may also be configured as a vacuum box and press roller corresponding structure, which is specifically referred to as the structure of the third belt clamping device 1001 and the fourth belt clamping device 1002 hereinafter.

As shown in fig. 7 and 8, the pre-cutting device 900 is located at a back stage position of the heat sealing device 700, and the pre-cutting device 900 is used to form a virtual tangent line 1704 in the middle of the heat sealing bar 1705.

In actual construction, the second clamp 906 is angled to form a block structure, and the bed knife blade 907 is fitted into a groove of the bed knife mandrel 905, which is matched with the angle of the bed knife mandrel, and the bed knife blade 907 is fixed by the second clamp 906, which is small at the bottom and large at the top. The second jig 906 is provided at a height of about half the height of the bed blade 907 in order to provide a thickness adjusting member 908 outside the second jig 906, and the thickness adjusting member 908 is fixed to the circumference of the bed blade mandrel 905. The thickness of the thickness adjusting member 908 can be adjusted to cut the packaging unit 1702 with different thicknesses, that is, when the thickness of the packaging unit 1702 is changed, in order to achieve the best effect of cutting dotted lines uniformly in the range of heat-seal embossing, only the thickness adjusting member 908 needs to be replaced without replacing the bed knife blade 907 and the second clamp 906, because the outer circle grinding is needed after the bed knife blade 907 and the second clamp 906 are replaced and installed, so as to ensure the consistency of the bed knife blade 907 on the circumference, thereby greatly saving manpower and material resources and improving the performance of the device. The bed knife blades 907 and the second clamps 906 and the thickness adjusting pieces 305 are uniformly arranged on the circumference and in the same number, and the blades 904 of the upper roller correspond to the bed knife blades 907 of the lower roller in the number and the positions.
