[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] like Figure 1 As shown, the cutting unit 1 further includes: a blade roller 11 and an anvil roller 12; the blade roller 11 is provided with at least one cutting blade adapted to the anvil roller 12; the anvil roller 12 is provided with a plurality of first adsorption holes and a plurality of second adsorption holes; the plurality of first adsorption holes cooperate to form a first adsorption area for adsorbing the cut strip of sanitary raw material; the plurality of second adsorption holes cooperate to form a second adsorption area for adsorbing the cut strip of sanitary raw material.
[0020] Optionally, the first conveying unit 2 includes: a first transfer wheel 21 and a plurality of first suction cups for adsorbing the cut strip-shaped sanitary raw materials on the first adsorption area; the plurality of first suction cups are arranged at equal intervals on the first transfer wheel 21; the first transfer wheel 21 is disposed on one side of the first discharge end of the anvil roller 12.
[0021] Optionally, the second conveying unit 3 includes: a second transfer wheel 31 and a plurality of second suction cups for adsorbing the cut strip-shaped sanitary raw materials on the second adsorption area; the plurality of second suction cups are equidistantly arranged on the second transfer wheel 31; the first transfer wheel 21 is arranged on one side of the second discharge end of the anvil roller 12 and is arranged in parallel with the first transfer wheel 21.
[0022] In this embodiment, as Figure 1-3 As shown, continuous strip-shaped raw material is cut by the cutter roller 11 and the anvil roller 12 into segmented sheets. The sheets are arranged alternately, and adjacent sheets are symmetrical in shape. The anvil roller 12 has a negative pressure adsorption function through the first and second adsorption holes provided thereon, and the sheets can be adsorbed and transported by the anvil roller 12 to the first transfer wheel 21 or the second transfer wheel 31. The negative pressure adsorption area of the anvil roller 12 is divided into two parts: a number of first adsorption holes cooperate to form a first adsorption area for adsorbing the cut strip-shaped sanitary raw material, and a number of second adsorption holes cooperate to form a second adsorption area for adsorbing the cut strip-shaped sanitary raw material. The first... The area where the adsorption region connects with the transfer wheel is an intermittent negative pressure zone; the second adsorption region on the anvil roller 12 and the area up to the point where the anvil roller 12 connects with the transfer wheel are continuous negative pressure zones; the two negative pressure zones can independently control the on / off state of the negative pressure; during normal operation, the continuous negative pressure zone maintains the negative pressure on, that is, the anvil roller 12 can stably adsorb the sheet in the continuous negative pressure zone; the negative pressure in the intermittent negative pressure zone is periodically on and off, with the negative pressure being off once every other sheet; when the negative pressure in the intermittent negative pressure zone is off, the anvil roller cannot adsorb the sheet, and the sheet is adsorbed and transferred by the transfer wheel; when the negative pressure in the intermittent negative pressure zone is on, the anvil roller 12 continues to adsorb the sheet until it is conveyed onto the second transfer wheel 31.
[0023] Further, the first variable-pitch conveying unit 4 includes: a first variable-pitch wheel 41, several outer suction cups 42 for adsorbing cut strip-shaped sanitary raw materials, several inner suction cups 43 for adsorbing cut strip-shaped sanitary raw materials, a swing arm 44, a cam bearing 45, a cam disk 46, and several lead screws 47; the cam disk 46 is installed on one side of the first variable-pitch wheel 41; the several lead screws are rotatably mounted on the first variable-pitch wheel 41; each end of the suction cups is provided with a lead screw nut 48; the outer suction cups are connected via... The lead screw nut 48 is slidably mounted on one end of the lead screw 47; the inner adsorption disk 43 is slidably mounted on the other end of the lead screw 47 via the lead screw nut 48; the extended end of the lead screw 47 near the outer adsorption disk 42 passes through the side wall of the first variable pitch wheel 41 and is fixedly connected to one end of the swing arm 44; the other end of the swing arm 44 is fixedly connected to the cam bearing 45; the cam disk 46 is provided with a groove adapted to the cam bearing 45; the cam bearing 45 is rotatably housed in the groove.
[0024] In this embodiment, as Figure 1-3 As shown, after being conveyed by the first transfer wheel 21 or the second transfer wheel 31, the sheets are all conveyed onto the first variable-pitch wheel 41. Specifically, for staggered sheets, the conveying distances from the first transfer wheel 21 to the first variable-pitch wheel 41 are unequal compared to those from the second transfer wheel 31 to the first transfer wheel 21. Setting a suitable difference in conveying distance allows each pair of sheets to be aligned directly opposite each other on the transfer wheel. The first variable-pitch wheel 41 has several pairs of outer adsorption disks 42 and inner adsorption disks 43. The adsorption disks can simultaneously move laterally outwards and inwards while rotating. Each outer adsorption disk 42 and inner adsorption disk 43 is equipped with a lead screw nut 48, which is driven by a lead screw 47, which is driven by a swing arm 44. One end of the swing arm 44... Fixed to the lead screw 47, it can rotate around the axis of the lead screw 47; the other end of the swing arm 44 is equipped with a cam bearing 45, which is embedded in the groove of the cam disk 46; when the variable pitch wheel rotates, the cam bearing 45 moves centrifugally or centripetally along the groove, causing the swing arm 44 to swing, thereby causing the lead screw 47 to rotate, thereby causing the adsorption disk and the adsorption plate to move laterally to the outside and inside respectively; in particular, since the swing angle of the swing arm 44 is small, the lead screw 47 needs to be a large lead screw 47 with both positive and negative threads; the lateral movement distance of the outer adsorption disk 42 and the inner adsorption disk 43 is determined by the groove curve of the cam disk 46; by changing the cam disk 46 with different groove curves, the lateral movement distance of the outer adsorption disk 42 and the inner adsorption disk 43 can be changed, thereby changing the lateral spacing of the cut strip of sanitary raw material.
[0025] Furthermore, the second variable-pitch conveying unit 5 includes: a second variable-pitch wheel 51, a plurality of suction cup groups 52 for adsorbing the cut strip-shaped sanitary raw materials conveyed by the outer suction cup 42 or the inner suction cup 43, and a plurality of drive motors; the plurality of suction cup groups 52 are rotatably disposed on the second variable-pitch wheel 51; the plurality of drive motors are all mounted on the second variable-pitch wheel 51, and their outputs are respectively connected to the plurality of suction cup groups 52 in a one-to-one transmission connection.
[0026] In this embodiment, as Figure 1-3 As shown, several suction cup groups 52 are coaxially arranged on the second variable pitch wheel 51, and each suction cup group 52 is driven by an independent servo motor. The speed of the servo motor needs to be controlled according to a specific speed curve. During operation, at the junction of the first variable pitch wheel 41 and the second variable pitch wheel 51, the suction cups adsorb the sheet on the variable pitch wheel at a speed of v1. After adsorption, the speed of the suction cups increases. When in contact with the main material 7 on the main material conveying unit 6, the suction cups rotate at a speed of v2 and release the sheet (cut strip of sanitary raw material) and attach it to the main material 7. After release, the speed of the suction cup group 52 increases to v3 and maintains the speed of v3 for a period of time. Finally, it decelerates to v1 and returns to the junction of the first variable pitch wheel 41 and the second variable pitch wheel 51, and repeats the above process. By increasing the speed v2 when the suction cup group 52 releases the sheet (cut strip of sanitary raw material), the longitudinal distance between the sheets (cut strip of sanitary raw material) can be increased, thereby increasing the longitudinal spacing of the sanitary main material 7 on the composite material.
[0027] Furthermore, the main material conveying unit 6 includes: a rotating roller 61 for conveying the main sanitary material 7; the rotating roller 61 is disposed below the second variable pitch wheel 51 to cooperate with the second variable pitch wheel 51 to attach the cut strip of sanitary raw material to the main sanitary material 7.
[0028] This utility model discloses a hygiene product molding system with a stable overall structure and convenient installation. By utilizing the cooperation of the first variable-pitch conveying unit 4 and the second variable-pitch conveying unit 5, it can realize the production and processing of hygiene products of different sizes, effectively improving production and processing efficiency.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
