[0002] A sanitary napkin is a sanitary product used by women during menstruation. Generally, sanitary napkins on the market are in boxed or bagged forms. Their structure is usually a composite form of a single piece + release paper, which is packed into a box or a bag. The production equipment for the single-piece form generally mainly includes a sheet material conveying device, a release paper conveying device, a coating device, and a slicing device. The sheet material conveying device is composed of a belt conveying device, a transfer device, a first air suction conveying device, an alignment device, and a belt conveying device. The sheet material device transports and arranges the sanitary napkins. The release paper conveying device is composed of a glue gun, a material deviation corrector, a second traction device, a tension storage device, a unwind device, and a break and connect device. The release paper conveying device mainly completes operations such as the traction, processing, and material change of the release paper. The coating device is composed of a first traction device, a coating adsorption device, an exhaust compaction device, a sealing and cutting device, a second air suction conveying device, and a pressing device. The coating device directly enables the release paper and the sanitary napkin to be coated. Finally, the slicing device performs slicing, and then it is manually or automatically packed into a box or a packaging bag by a packing device.

[0022] The present invention further provides a production process for a production device of a roll-type sanitary napkin according to the above, and the production process includes the following steps:

[0023] Step A: Preliminary preparation: Place the wrapping paper on the disconnection and feeding device for preparation. Pull out one end of the wrapping paper and perform unwinding operation through the unwinding device. Then, perform tension straightening through the tension storage device, and then sequentially pass through the second traction device, the first traction device, the wrapping adsorption device, the exhaust compaction device, the sealing and cutting device, the second air suction conveying device, the pressing device, and the winding device. The winding device winds one end of the wrapping paper; Insert the paper tube into the middle of the disassembly roller. There are two disassembly rollers, which are directly placed into the telescopic clamp and the bracket.

[0024] Step B: Start operation: Place the sanitary napkin on the belt conveying device. The belt conveying device conveys the sanitary napkin to the transfer device.

Since the glue gun is operating and one side of the wrapping paper has an adhesive layer, the wrapping paper and the sanitary napkin enter the wrapping adsorption device together. The output end of the wrapping adsorption device can directly adhere the side with the adhesive layer to the side without the adhesive layer, so that the wrapping paper wraps the sanitary napkin to form a semi-finished product. Then, the air in the semi-finished product is discharged and compacted through the exhaust compaction device, and it is conveyed to the sealing and cutting device for the setting of an easy-to-tear seal, and then conveyed to the second air suction conveying device and the pressing device for further conveying and pressing, and finally enters the winding device for the winding work of the paper tube and the semi-finished product to form a complete roll-type sanitary napkin.

The semi-finished products can enter the upper and lower conveyor rollers for exhaust and compaction;

[0033] The sealing and cutting device adopts a traditional paper roll sealing device machinery

[0034] The second air suction conveying device is the same as the first air suction conveying device;

[0035] The pressing device is used for re-pressing the semi-finished products;

[0099] In the early stage, the paper tube is inserted into the middle of the disassembly roller, and the disassembly roller is directly placed into the telescopic clip; the semi-finished roll-type sanitary napkin directly enters the rotating cylinder through the first conveying roller and the second conveying roller. The rotating cylinder is rotating, and the rotating frame is rotating. When the paper tube in the disassembly roller is close to the semi-finished roll-type sanitary napkin, due to the friction between the two sides, the disassembly roller can also be driven to rotate, so the semi-finished roll-type sanitary napkin is directly wound around the paper tube. During this process, the rotating frame slowly rotates to the bracket position, and the telescopic clip contracts, then the disassembly roller in the telescopic clip is placed into the bracket, the rotating frame resets, and the operator puts the disassembly roller with the paper tube into the telescopic clip again, waiting for the next operation;

[0100] When the disassembly roller on the bracket continuously winds the semi-finished roll-type sanitary napkin and directly reaches a certain quantity, the swinging air cylinder starts to swing to the right, directly breaks the semi-finished roll-type sanitary napkin, and a bundle of finished roll-type sanitary napkins is formed. The left and right moving air cylinder moves the bracket away, and the operator takes away the disassembly roller. At this time, the rotating frame rotates again, and the subsequent operations are repeated. Just take away a bundle of finished roll-type sanitary napkins from the disassembly roller.

[0101] The lifting air cylinder can adjust the distance between the first conveying roller and the second conveying roller.

[0102] In the present invention, the paper tube can be inserted into the special rotating roller in the toilet. The user can directly pull out the wrapping paper, tear it along the easy-to-tear seal, and then open the wrapping paper to take out the sanitary napkin; in the present invention, by referring to the principle of roll-type tissue paper, the common pumping method of sanitary napkins is changed, so as to achieve the effect of quickly taking the sanitary napkin; at the same time, the wrapping paper directly wraps the sanitary napkin, and the corresponding production equipment and process are directly designed, so that it can be quickly produced on the production line, and the quantity of a roll of sanitary napkins can reach 40-60, reducing unnecessary resource waste. At the same time, the overall production efficiency is improved, so as to achieve the effect of accelerating the production efficiency.
