[0132] A processing device 8 for processing the second assembly 500 into a final product, which can be a tearable small surgical drape.

[0133] Refer to Figure 4 and Figure 5 , Figure 4 which is a top view of the film materials in different processes during processing, Figure 5Schematic diagram of the three-dimensional structure of the film material in different processes during processing. This film material processing and manufacturing equipment can be applied to the manufacture of medical disposable tearable small surgical drapes. This disposable tearable small surgical drape is a disposable consumable used on the operating table, such as Figure 4 and Figure 5 shown. Its production process may successively include processes such as heat synthesis of a tearable transparent PE (A sheet) and a non-tearable transparent PE (B sheet) into a main sheet, corona treatment of the main sheet, punching of a highly absorbent non-woven fabric, heat sealing of the highly absorbent non-woven fabric and the main sheet, pasting a sandwich film on the main sheet, pasting a horizontal double-sided tape on the main sheet, pasting a longitudinal long tape on the tearable transparent PE (A sheet), pasting a longitudinal short tape on the non-tearable PE (B sheet), and punching at the position where the sandwich glue is pasted on the main sheet.

[0134] Refer to Figures 6 to 8 , Figure 6 which is a schematic diagram of the three-dimensional structure of the first feeding device 1, Figure 7 is a top view of the first feeding device 1, Figure 8 is a front view of the first feeding device 1. In some embodiments, the first feeding device 1 may include a first feeding mechanism 11. The first feeding mechanism 11 includes a material rack 111, an air shaft 112, a first powder brake 113, and a clutch 114. The air shaft 112 is installed on the material rack 111 for installing the raw material of the first type of film material 100. One end of the air shaft 112 is connected to the first powder brake 113 through the clutch 114.

[0135] The material rack 111 may be a frame structure. Slots are respectively provided at opposite ends of the material rack 111 for the two ends of the air shaft 112 to be inserted therein. Further, a cylinder 117 may be provided on one side of the material rack 111 close to the slot for limiting the two ends of the air shaft 112 to prevent the air shaft 112 from disengaging from the material rack 111.

[0136] Refer to together Fig. 9 , Fig. 9 which is a partial enlarged view near the clutch 114. The clutch 114 may include a spline shaft 1141, a first clutch part 1142, and a second clutch part 1143. The first feeding mechanism 11 further includes a telescopic cylinder 118 and a cylinder plate 119. The spline shaft 1141 is provided at the shaft end of the first powder brake 113. The first clutch part 1142 is movably installed on the spline shaft 1141 and is connected to the cylinder plate 119. The cylinder plate 119 is connected to the telescopic cylinder 118. The second clutch part 1143 is provided at one end of the air shaft 112.

[0137] Among them, the telescopic movement of the telescopic cylinder 118 can drive the cylinder plate 119 to move along the spline shaft 1141, so that the first clutch part 1142 and the second clutch part 1143 can be separated and connected.

[0138] The first feeding mechanism 11 may further include a slide rail assembly 115 and a deviation rectifying assembly 116. The slide rail assembly 115 is disposed at the lower end of the material rack 111, and the deviation rectifying assembly 116 is connected to the slide rail assembly 115 to drive the material rack 111 to move in the deviation rectifying direction, thereby adjusting the raw material position of the first type of film material 100. The slide rail assembly 115 may be a combination of a slide rail and a slider, and the slider may be disposed at the lower end of the material rack 111. The deviation rectifying assembly 116 may include a deviation rectifying motor, which is connected to the slide rail assembly 115 or the material rack 111 through a connecting member (such as a connecting block) to drive the material rack 111 to move so as to adjust the position of the first type of film material 100. The deviation rectifying motor may be a servo motor. The deviation rectifying direction may be perpendicular to the feeding direction of the first type of film material 100. In some embodiments, devices such as a camera monitor or a displacement sensor may also be configured to monitor the raw material installation position and the feeding direction of the first type of film material 100, so as to determine whether the feeding meets the requirements.

[0139] For another example Figure 2 As shown, the first feeding device 1 further includes a first active traction mechanism 12. The first active traction mechanism 12 is disposed adjacent to the first feeding mechanism 11 to traction the first type of film material 100 to move forward.

[0140] Referring to Figures 10 to 13 , Fig.10 is a three-dimensional structural schematic diagram of the first active traction mechanism 12, Fig.11 is a front view of the first active traction mechanism 12, Fig.12 is a sectional structural schematic diagram of the first active traction mechanism 12 in the A-A direction, Fig.13 is a sectional structural schematic diagram of the first active traction mechanism 12 in the B-B direction. Combining Fig.10 and Fig.13 it can be known that the first active traction mechanism 12 includes a traction frame 121 and a first roller 122, a second roller 123, a third roller 124, a fourth roller 125, a fifth roller 126, a sixth roller 127, a first driving member 128, a second powder brake 129, a first swing rod 1210 and a first displacement sensor 1211 mounted on the traction frame 121. The traction frame 121 may include two relatively disposed side plates 121a, a plurality of first connecting rods 121b that connect the two side plates 121a and are spaced apart, and at least one second connecting rod 121c that connects the two side plates 121a. In some embodiments, the two side plates 121a may be provided with a plurality of card slots for mounting the shafts of the above-mentioned rollers.

[0141] For another example Fig.13As shown, the first roller 122 and the second roller 123 are arranged adjacent to each other and in contact with each other. The first roller 122 is located above the second roller 123, and both are arranged on the traction frame 121 near the first feeding mechanism 11. The second roller 123 is connected to the first driving member 128 to rotate under the drive of the first driving member 128.

[0142] The third roller 124, the fourth roller 125 and the fifth roller 126 are arranged on the side of the traction frame 121 away from the first feeding mechanism 11. Among them, the third roller 124 and the fourth roller 125 are arranged adjacent to each other and in contact with each other. The third roller 124 is located below the fourth roller 125, and both the third roller 124 and the fourth roller 125 are located below the fifth roller 126. The third roller 124 is connected to the second powder brake 129, and the second powder brake 129 can eliminate the rotational inertia of the third roller 124 and the fourth roller 125, so that the film material always has a certain tension. In some embodiments, the plane where the lowermost side of the outer periphery of the fifth roller 126 is located is higher than the plane where the lowermost side of the outer periphery of the first roller 122 is located.

[0143] Again, Fig.13 As shown, the sixth roller 127 is located between the first roller 122 and the third roller 124 and is connected to one end of the first swing rod 1210. The other end of the first swing rod 1210 is connected to the traction frame 121 and can be rotatably connected to the second connecting rod 121c. There are clearance spaces between the two axial ends of the sixth roller 127 and the traction frame 121 respectively, and the first displacement sensor 1211 is connected to the first swing rod 1210.

[0144] During the working process, the first type of film material 100 drawn by the first feeding mechanism 11 winds around the first roller 122 from the gap between the first roller 122 and the second roller 123 to the outer periphery of the fifth roller 126, then winds from the outer periphery of the fifth roller 126 to the sixth roller 127, then winds from the sixth roller 127 to the third roller 124, and finally is sent out from the gap between the third roller 124 and the fourth roller 125 and enters the next mechanism such as the bridge mechanism 13.

[0145] It can be understood that assuming that the speed of the first type of film material 100 at the discharging position (rotating around the fourth roller 125) is constant and the rotating speed of the feeding position (the second roller 123) is slow, the coiling length of the first type of film material 100 from the feeding position (the second roller 123) to the discharging position (the fourth roller 125) will gradually decrease, and the sixth roller 127 drives the first swing rod 1210 to rotate (as Fig.12Rotating in the clockwise direction as shown, the value of the first displacement sensor 1211 decreases. This decreased value is fed back to the servo control system, thereby increasing the rotational speed of the first driving member 128 and increasing the rotational speed at the feeding location (at the second roller 123). Conversely, if the speed of the first driving member 128 is too fast, the length of the first type of film material 100 from the feeding location (at the second roller 123) to the discharging location (at the fourth roller 125) will gradually become longer. The sixth roller 127 will drive the first swing rod 1210 to rotate (as Fig.12 rotating in the counterclockwise direction as shown), causing the value of the first displacement sensor 1211 to increase. This increased value is fed back to the servo control system, causing the speed of the first driving member 128 to slow down. Similarly, when the speed at the discharging location (at the fourth roller 125) of the first type of film material 100 changes, the speed of the first driving member 128 will also change accordingly.

[0146] During the working process, the first type of film material 100 conveyed by the first active traction mechanism 12 first winds around the outer peripheral upper side of the first transition wheel 132, then winds downward around the outer peripheral lower side of the second roller 123, then winds upward from the outer peripheral lower side of the second roller 123 to the upper side of the third roller 124, then enters downward to the lower side of the fourth roller 125, and finally is sent out by the fourth roller 125.

[0147] Refer again to Figure 2 , in some embodiments, the first feeding device 1 further includes a bridging mechanism 13. The bridging mechanism 13 is disposed adjacent to the first active traction mechanism 12, and the bridging mechanism 13 and the first feeding mechanism 11 are respectively located on the front and rear sides of the first active traction mechanism 12.

[0148] Refer to Figures 14 to 16 , Fig.14 is a three-dimensional structural schematic diagram of the bridging mechanism 13, Fig.15 is a front view of the bridging mechanism 13, Fig.16 is a top view of the bridging mechanism 13. The bridging mechanism 13 includes a bridge frame 131, a first transition wheel 132, a second transition wheel 133, a third transition wheel 134, and a fourth transition wheel 135. The bridge frame 131 is generally a frame-shaped structure, and the first transition wheel 132, the second transition wheel 133, the third transition wheel 134, and the fourth transition wheel 135 can all be disposed on the bridge frame 131. Among them, the first transition wheel 132, the second transition wheel 133, and the third transition wheel 134 are sequentially arranged at intervals and in parallel, and can be in the same plane. The first transition wheel 132 can also be disposed closer to one side of the fifth roller 126, and the first transition wheel 132 is located above the fifth roller 126. The fourth transition wheel 135 is disposed below the third transition wheel 134.

[0149] Again, such as Figure 2As shown, in some embodiments, the second feeding device 2 is spaced apart from the first feeding device 1, and the feeding directions of the two are the same. The second feeding device 2 includes a second feeding mechanism 21 and a second active traction mechanism 22. The structure of the second feeding mechanism 21 can be the same as that of the first feeding mechanism 11, and the structure of the second active traction mechanism 22 can be the same as that of the first active traction mechanism 12. The specific structure of the second feeding device 2 can be implemented with reference to the first feeding device 1, and will not be repeated here.

[0150] In some embodiments, the second feeding device 2 can be arranged in the bridge frame 131, such as being located below the top of the bridge frame 131, so that the layout space of the equipment mechanism can be saved.

[0151] For example Figure 2 As shown, in some embodiments, the film material processing and manufacturing equipment further includes a stacking device 14 for overlapping the first type of film material 100 and the second type of film material 200, and the stacking device 14 is respectively arranged adjacent to the bridge mechanism 13 and the second active traction mechanism 22.

[0152] See also Figures 17 to 20 , Fig.17 is a schematic diagram of the three-dimensional structure of the stacking device 14, Fig.18 is a front view of the folding device 14, Fig.19 is a CC cross-sectional structural diagram of the stacking device 14, Fig. 20 is a schematic diagram of the DD-direction cross-sectional structure of the stacking device 14, combined with Fig.17 and Fig. 20 It can be known that the stacking device 14 includes a stacking frame 141 and a first rubber roller 142, a second rubber roller 143, a third rubber roller 144, a fourth rubber roller 145, a movable roller 146, a second driving member 147 and a second displacement sensor 148 arranged on the stacking frame 141. The stacking frame 141 can be a relatively compact frame structure. The first rubber roller 142, the second rubber roller 143, the third rubber roller 144 and the fourth rubber roller 145 are arranged in sequence and adjacent to each other, and the first rubber roller 142 is arranged close to the side of the fourth transition wheel 135, and the second rubber roller 143 is connected to the second driving member 147.

[0153] For example Fig.19 and Fig. 20 As shown, the movable roller 146 is installed on the stacking frame 141 through a slide bar assembly 149, and is located between the third rubber roller 144 and the fourth rubber roller 145, and is connected to the second displacement sensor 148. The connection between the second displacement sensor 148 and the movable roller 146 is used to obtain the position information of the movable roller 146, so as to obtain the transmission information of the film material. The slide bar assembly 149 may include two slide bars installed on opposite sides of the stacking frame 141, and the two ends of the movable roller 146 are slidably installed on the slide bars through sliders.

[0154] During the working process, the first type of film material 100 first enters the first rubber roller 142 through the fourth transition roller 135, and the second type of film material 200 enters the first rubber roller 142. The lower side edge of the first type of film material 100 and the upper side edge of the second type of film material 200 are overlapped to form a laminated film material. Specifically, the side edge of the first type of film material 100 is overlapped on the side edge of the second type of film material 200 facing the first type of film material 100.

[0155] Further, the laminated film material enters the first rubber roller 142, winds downward from the upper side surface of the outer circumference of the first rubber roller 142 around the lower side surface of the second rubber roller 143 and then reversely upward around the upper side surface of the third rubber roller 144, then winds downward around the lower side surface of the outer circumference of the movable roller 146, and then winds upward around the fourth rubber roller 145 and is sent out.

[0156] In some embodiments, the overlapping size of the first type of film material 100 and the second type of film material 200 is 15 mm to 20 mm in width, and specifically it can be set to 15 mm.

[0157] Again, Figure 2 As shown, in some embodiments, the first heat-sealing device 3 is arranged adjacent to the laminating device 14.

[0158] Refer to Fig.21 , Fig.21 FIG. is a three-dimensional structural schematic diagram of the first heat-sealing device 3. The first heat-sealing device 3 includes a heat-sealing machine frame 31, a third driving member 32 and a heat-sealing pressing rod 33. A workbench 311 is provided on the heat-sealing machine frame 31. The third driving member 32 is located above the workbench 311, and the heat-sealing pressing rod 33 is connected to the output end of the third driving member 32.

[0159] During the working process, the laminated film material is conveyed into the workbench 311, and the third driving member 32 drives the heat-sealing pressing rod 33 to move up and down to heat-seal the heat-sealing required part of the laminated film material, and then heat-seal the first type of film material 100 and the second type of film material 200 together to form a first assembly 400.

[0160] In some embodiments, an installation beam may be provided above the workbench 311 on the heat-sealing machine frame 31. The third driving member 32 is installed on the installation beam, and the output end of the third driving member 32 is connected to the heat-sealing pressing rod 33 through a first floating joint 34. The third driving member 32 may be a cylinder.

[0161] Again, Fig.21 As shown, the first heat-sealing device 3 further includes a flange linear bearing 35 provided on the installation beam and a linear guide rod 36 passing through the flange linear bearing 35 and connected to the heat-sealing pressing rod 33, which is used to guide the heat-sealing pressing rod 33 to make the heat-sealing pressing rod 33 move more stably when moving up and down.

[0162] The specific working process is as follows: At the starting position, the heat-sealing press bar 33 is lifted. After the laminated film material enters the workbench 311 and advances a set length, it stops moving, and the heat-sealing press bar 33 is pressed down. At this time, the heating wire under the heat-sealing press bar 33 instantaneously heats up (generally about 0.2 seconds) under the control of the PLC in the control box, and then cools for a period of time (generally 1 to 2 seconds), and the first type of film material 100 and the second type of film material 200 are heat-sealed together to form the first assembly 400. Then, the heat-sealing press bar 33 is lifted, and the heat-sealing process is cycled. The heating wire can be a heating wire with a width of about 3MM.

[0163] Again, Figure 2 As shown, the film material processing and manufacturing equipment further includes a corona device 15, and the corona device 15 can be arranged adjacent to the first heat-sealing device 3.

[0164] Refer to Figure 22 to Figure 24 , Fig. 22 which is a three-dimensional structure schematic diagram of the corona device 15, Fig.23 and this Fig.23 is a front view of the corona device 15. The corona device 15 includes a corona frame 151 and a first passive roller 152, a second passive roller 153, a third passive roller 154, a fourth passive roller 155, a fifth passive roller 156, a first flattening roller 157, a corona zero-potential roller 158, a high-potential discharge electrode 159 and a discharge power supply 1510 arranged on the corona frame 151.

[0165] Again, Fig.23 As shown, the first passive roller 152 and the second passive roller 153 are respectively arranged close to one side of the first heat-sealing device 3. The first passive roller 152 is located below the second passive roller 153. The first flattening roller 157 is located between the first passive roller 152 and the second passive roller 153. The third passive roller 154 is arranged in parallel at an interval with the second passive roller 153. The fourth passive roller 155 and the fifth passive roller 156 are arranged in parallel at an interval and are located between the second passive roller 153 and the third passive roller 154. The fourth passive roller 155 is arranged close to one side of the second passive roller 153. The corona zero-potential roller 158 is located between the fourth passive roller 155 and the fifth passive roller 156.

[0166] The high-potential discharge electrode 159 is connected to the discharge power supply 1510, and the high-potential discharge electrode 159 can be located above the corona zero-potential roller 158.

[0167] During the working process, the first assembly 400 from the first heat-sealing device 3 sequentially passes through the first passive roller 152, the first flattening roller 157, the second passive roller 153, the fourth passive roller 155, the corona zero-potential roller 158, the fifth passive roller 156, and the third passive roller 154. When passing through the corona zero-potential roller 158, the high-potential discharge electrode 159 corona-treats the part to be corona-treated of the first assembly 400. The start and end times of the discharge of the high-potential discharge electrode 159 can be controlled by the PLC in the control box, and the function of corona treatment is to enhance the bonding strength between the first assembly 400 (main single) and the subsequent sandwich glue.

[0168] Please refer to Figure 2 and Fig.25 , Fig.25 , which is a partial enlarged view of the film material processing and manufacturing equipment. In some embodiments, the third feeding device 4 includes a third feeding mechanism 41 and a third active traction mechanism 42. The structure of the third feeding mechanism 41 can be the same as that of the first feeding mechanism 11, and the structure of the third active traction mechanism 42 can be the same as that of the first active traction mechanism 12, and can be implemented with reference to the first feeding device 1, which will not be elaborated here.

[0169] During the working process, the discharging direction of the third type of film material 300 on the third feeding device 4 can be opposite to the discharging direction of the first type of film material 100. For example, the first type of film material 100 and the second type of film material 200 can be discharged from right to left, and the third type of film material 300 can be discharged from left to right.

[0170] Another example Fig.25 As shown, the film material processing and manufacturing equipment in some embodiments of the present invention provides a first punching device 5, which overcomes the deficiencies of related punching technologies. To better illustrate the working principle and advantages of the first punching device 5, the punching solutions in related technologies will be described in detail below with reference to Figure 26 to Figure 28

[0171] In related technologies, the punching of flexible film materials (such as, highly absorbent non-woven fabrics) mainly has the following three types of forms:

[0172] The first type of form is to use a rotary cutter for rotary cutting (refer to Fig.26 ). This type of punching is particularly suitable for occasions with large quantities and few varieties. It can well solve the conveyance of highly absorbent non-woven fabrics. However, this type of rotary cutting roller is very expensive, it is very troublesome to replace the cutting tool each time, and the maintenance cost of the cutting edge is also very high. Therefore, it is not suitable for the punching process requirements of highly absorbent non-woven fabrics for tearable small surgical drapes with few varieties and small quantities.

[0173] The second type of form is punching in the form of a metal stamping die (refer to Fig. 27), For this type of mold, the service life of the mold is extremely long. When punching materials such as highly absorbent non-woven fabrics, the cost of mold repair hardly needs to be considered. However, it is very difficult to manufacture a mold that can punch materials such as highly absorbent non-woven fabrics with large apertures, and the installation and commissioning are also very difficult. For this type of material, such as highly absorbent non-woven fabrics, this type of mold is only suitable for punching small apertures. For this structure of the mold, it is also very difficult to solve the problem of conveying highly absorbent non-woven fabrics with large holes.

[0174] The third type is the laser knife mold type (refer to Fig.28 ), For this type of mold, the manufacturing cost of the mold itself is very low, and the punching effect is also very good. However, it directly punches with a special conveyor belt as the bottom plate and punches as a whole. As a result, the requirements for the conveyor belt are extremely high, and the requirements for the overall mechanical rigidity are also extremely high. The cost of the special conveyor belt is high, and its service life is low.

[0175] Refer to Fig.29 and Fig.30 , Fig.29 is a schematic principle diagram of the first punching device 5, Fig.30 is a schematic three-dimensional structure diagram of the first punching device 5. The first punching device 5 may include:

[0176] A frame 51, which can be a frame structure and is used for installing and bearing the relevant components of the first punching device 5;

[0177] A conveyor belt 52, which is used to convey the third type of film material 300. The conveyor belt 52 is annular and is rotatably installed. During the working process, the third type of film material 300 from the third feeding device 4 is placed above the upper part of the conveyor belt 52 and is conveyed forward by the conveyor belt 52. After the third type of film material 300 is punched, it is sent to the next processing link. In some embodiments, the third type of film material 300 includes but is not limited to highly absorbent non-woven fabrics, and the conveyor belt 52 includes but is not limited to a sheet-based flat belt;

[0178] A laser knife mold mechanism 53, which is installed on the frame 51 and is located above the conveyor belt 52;

[0179] A metal thin plate 54, which is installed on the frame 51 and is arranged between the conveyor belt 52 and the third type of film material 300. The metal thin plate 54 is arranged on the conveying path of the third type of film material 300 and is directly below the cutting edge 531 of the laser knife mold; The metal thin plate 54 may include but is not limited to a stainless steel plate. The metal thin plate 54 may be a whole plate structure, and its two ends are installed on the frame 51. Alternatively, the metal thin plate 54 may be installed on the frame 51 through a bracket, and the bracket can adjust the tightness of the metal thin plate 54. The thickness of the metal thin plate 54 may be 0.1-1 mm. Specifically, the thickness of the metal thin plate 54 may be 0.5 mm.

[0180] The roller mechanism 55 is installed on the frame 51 and can be located between the upper part and the lower part of the conveyor belt 52.

[0181] Refer to Fig.32 and Fig.33 , Fig.32 which is a schematic three-dimensional structure diagram of the roller mechanism 55 of the first punching device 5. Fig.33 which is a top view of the roller mechanism 55 of the first punching device 5. The roller mechanism 55 includes a first mounting frame 551 and a roller 552. A track 5511 for the roller 552 to roll on is provided on the first mounting frame 551. A convex platform 5511A protruding upward is provided in the middle of the track 5511. The convex platform 5511A is located below the metal thin plate 54 and below the upper part of the conveyor belt 52. Both ends of the convex platform 5511A are in an inclined transition, so that the roller 552 rolls more smoothly up and down.

[0182] In some embodiments, the moving direction of the roller 552 intersects with the moving direction of the conveyor belt 52. For example, the moving direction of the roller 552 can be set at a certain angle with the conveying direction of the conveyor belt 52 (i.e., the conveying direction of the third type of film material 300). Specifically, the moving direction of the roller 552 can be perpendicular to the conveying direction of the conveyor belt 52.

[0183] Combined with Fig.32 and Fig.33 as shown, in some embodiments, the roller mechanism 55 includes a driving component 553 for driving the roller 552 to move.

[0184] For another example Fig.33 as shown, the first mounting frame 551 is provided with a slide rail 5512 opposite to the track 5511, and a slide plate 5513 movably mounted on the slide rail 5512. The number of the tracks 5511 can be two, and the two tracks 5511 are arranged opposite to each other at intervals. The number of the slide rails 5512 is also two, and the two slide rails 5512 are arranged at a position below the track 5511 and are separated from the track 5511 by a certain distance. The slide plate 5513 can be slidably connected to the slide rail 5512 through a slider.

[0185] In some embodiments, the first mounting frame 551 includes two side plates 5514 arranged opposite to each other, and both the track 5511 and the slide rail 5512 are arranged between the two side plates 5514.

[0186] For another example Fig.32As shown, the drive assembly 553 includes a drive motor 5531 and a transmission lead screw 5532. The drive motor 5531 is installed on a side plate 5514, and the drive shaft of the drive motor 5531 is connected to a drive synchronous pulley 5533. The first end of the transmission lead screw 5532 is installed on the side plate 5514, and a driven synchronous pulley 5534 is connected to one end of the transmission lead screw 5532. The drive synchronous pulley 5533 and the driven synchronous pulley 5534 can be located on the same side of a side plate 5514, and the drive synchronous pulley 5533 and the driven synchronous pulley 5534 are connected by a synchronous belt 5535.

[0187] The nut 5536 of the transmission lead screw 5532 is connected to the slide plate 5513. When the drive motor 5531 drives the transmission lead screw 5532 to rotate, the nut 5536 moves axially along the lead screw 5532, thereby driving the slide plate 5513 to move along the slide rail 5512. In some embodiments, the drive motor 5531 can be a servo motor, and the servo motor has higher precision.

[0188] Again, Fig.33 As shown, in some embodiments, there is a rolling bearing 552A at each end of the roller shaft 552. A support shaft 5515 is provided on the slide plate 5513. The support shaft 5515 is installed on the slide plate 5513 through a mounting seat, and the support shaft 5515 is connected to the roller shaft 552 through a link assembly 554. Combining Fig.32 it can be known that the link assembly 554 can include a connecting plate, and connecting holes are respectively provided at both ends of the connecting plate. Among them, one connecting hole is sleeved on the outer periphery of the axial end of the support shaft 5515, and the other connecting hole is sleeved on the axial end of the roller shaft of the roller shaft 552, so that when the roller shaft 552 moves on the track 5511, the rolling bearing 552A rolls on the track 5511.

[0189] Again, Fig.32 As shown, in some embodiments, the roller shaft mechanism 55 includes a self-rotation drive assembly 555 connected to the roller shaft 552 to drive the roller shaft 552 to rotate. The self-rotation drive assembly 555 can include a self-rotation drive motor installed on the slide plate 5513. The output end of the self-rotation drive motor is connected to a first synchronous pulley, and a second synchronous pulley is provided on the roller shaft 552. A synchronous belt connects the first synchronous pulley and the second synchronous pulley respectively. The self-rotation drive motor drives the roller shaft 552 to rotate through the first synchronous pulley, the synchronous belt and the second synchronous pulley, so that the roller shaft 552 rotates while moving in parallel, so as to ensure that the contact part between the roller shaft 552 and the conveyor belt 52 only rolls and does not slide. In some embodiments, the self-rotation drive motor is a servo motor.

[0190] Please refer to Fig.31 , Fig.31It is a partial enlarged view of the laser die-cutting mechanism 53, which can be installed on the frame 51 through a fixing plate (not shown). The laser die-cutting mechanism 53 may include a mounting plate 532 and a driving member 533 connected to the mounting plate 532. The mounting plate 532 is provided with a laser die-cutting edge 531 on the side facing the metal sheet 54. The driving member 533 may further include a cylinder 5331 and a second floating joint 5332. The cylinder 5331 is connected to the mounting plate 532 through the second floating joint 5332 and is used to drive the laser die-cutting edge 531 to move up and down. The cylinder 5331 can be installed on the above-mentioned fixing plate.

[0191] In some embodiments, the laser die-cutting mechanism 53 further includes a linear bearing 534 and a guide shaft 535 passing through the linear bearing 534 and connected to the mounting plate 532. The linear bearing 534 can also be fixed on the above-mentioned fixing plate.

[0192] In some embodiments, the laser die-cutting mechanism 53 further includes a pull rod 536. Adjusting nuts 537 can be provided at both ends of the pull rod 536 above the mounting plate 532. The adjusting nuts 537 are used to accurately control the descending distance of the laser die-cutting edge 531.

[0193] In some embodiments, the laser die-cutting mechanism 53 further includes a manual nut 538 and a pressing strip 539. The pressing strip 539 is used to support and position the laser die. The manual nut 538 passes through the mounting plate 532 and is connected to the pressing strip 539. During the die change process, the manual nut 538 can be first turned, then the pressing strip 539 can be loosened, and then the laser die can be taken out. Next, a new laser die can be replaced, and finally the manual nut 538 can be tightened to complete the die change work.

[0194] Again, Fig.29 and Fig.32As shown, in some embodiments, the conveyor belt 52 is separated by the metal sheet 54, and supports the third type of film material 300 (such as highly absorbent non-woven fabric) on both sides of the metal sheet 54, and is transported to one side for a required distance and stops (the conveyor belt 52 can be controlled by a control device such as a PLC industrial computer). At this time, the metal sheet 54 does not move, and the laser die cutting edge 531 of the laser die cutting mechanism 53 is downwardly pressed against the highly absorbent non-woven fabric and positioned. The roller 552 rolls along the bottom of the upper part of the conveyor belt 52, and stops at a low position on one side of the track 5511 (such as the left side of the boss 5511A), through the boss 5511A, and then at a low position on the other side of the track 5511 (such as the right side of the boss 5511A). When the roller 552 passes through the boss 5511A, the busbar above the roller 552 partially contacts the conveyor belt 52, the conveyor belt 52 partially contacts the metal sheet 54, and the metal sheet 54 partially contacts the laser cutter edge 531 of the laser cutter mechanism 53 through the third type of film material 300, thereby partially cutting the third type of film material 300 (such as highly absorbent non-woven fabric). The roller 552 continuously rolls along the conveyor belt 52, thereby achieving blanking of the entire laser cutter mechanism 53. After blanking, the laser cutter 53 is lifted.

[0195] As can be seen from the above, as long as the roller 552 can roll smoothly, the laser die edge 531 floats and contacts the metal sheet 54 through the third type film material 300, and the laser die edge 531 can be punched with a very small punching force (only as long as Fig.28 The third type of laser knife die shown in the figure can achieve blanking with a few percent of the blanking force of the laser knife die, so the overall structural rigidity of the machine is not required to be high. Because there is a metal sheet 54 between them, the conveyor belt 52 can be made of an ordinary flat belt with a sheet base to meet the requirements and has a long service life.

[0196] The above-mentioned traction mechanism, driving member 533, driving motor 5531, self-rotating driving motor, etc. can all be controlled by a PLC industrial control computer to realize automated operation.

[0197] See also Fig.34 , Fig.34 300 is a schematic diagram of the structure of the third type of film material 300 after punching. As shown in the figure, the third type of film material 300 is in a rectangular ring shape after punching, wherein film material portion 301, film material portion 303, film material portion 304 and film material portion 305 are the film materials left after punching, and punching hole 302 is the punching position. The third type of film material 300 is a highly absorbent non-woven fabric, and the remaining material cut out by punching ( Fig.34 The area of ​​a single sheet is relatively large. If it is not collected, it will cause material waste. If it is collected manually, additional labor costs will be added, and the efficiency of manual collection is low. For this reason, the film material processing and manufacturing equipment may also include a residual material collection device 9 (such as Figure 2 ), for collecting the remaining material.

[0198] Please refer to Figure 35 to Figure 37 , Fig.35 which is a schematic perspective view of the residue collection device 9, Fig.36 and Fig.37 is a front view of the residue collection device 9. As shown in the figure, the residue collection device 9 includes a first bracket 91 disposed on the frame 51, a suction mechanism 92 disposed on the first bracket 91 for sucking the residue of the third type of film material 300, a receiving mechanism 93 disposed on the first bracket 91 for placing the residue of the third type of film material 300, and a driving mechanism 94 disposed on the first bracket 91 and connected to the suction mechanism 92 to drive the suction mechanism 92 to move so as to place the residue of the third type of film material 300 into the receiving mechanism 93. The first bracket 91 can be a frame structure. Specifically, it can be a frame assembled by a plurality of cross beams and longitudinal beams.

[0199] Again, as Fig.35 shown, in some embodiments, a pair of guide rails 911 are oppositely disposed on the first bracket 91, and the receiving mechanism 93 is disposed below one end of the guide rails 911 (as Fig.36 shown). The suction mechanism 92 includes a positioning plate 921, and the positioning plate 921 is movably mounted on the pair of guide rails 911 through a slider 922. The driving mechanism 94 is connected to the positioning plate 921 to drive the entire suction mechanism 92 to move back and forth in the horizontal direction.

[0200] Refer to Fig.35 and Fig.36 together. In some embodiments, the suction mechanism 92 may include a cylinder 923 mounted on the positioning plate 921 and a suction cup 924 connected to the cylinder 923. The cylinder 923 is used to drive the suction cup 924 to move up and down to suck the residue of the third type of film material 300.

[0201] In some embodiments, the suction mechanism 92 may further include a linear bearing 925 disposed on the positioning plate 921 and a guide shaft 926 passing through the linear bearing 925 and connecting the suction cup 924, which can play a role of connection and guidance, so that the suction cup 924 moves up and down more accurately and smoothly. In some embodiments, the cylinder 923 can also be replaced by a driving motor, that is, the driving motor is used to drive the suction cup 924 to move up and down. The suction cup 924 can be a needle-type suction cup.

[0202] In some embodiments, the suction mechanism 92 may include a suction cup mounting plate, and the suction cup 924 is detachably mounted on (such as detachably connected by a snap connection method or a threaded connection method) the suction cup mounting plate, which is convenient for replacing the suction cup 924.

[0203] Again, as Fig.35As shown, in some embodiments, the first bracket 91 includes a first side plate 912 and a second side plate 913 respectively arranged at two axial ends of the guide rail 911, and the driving mechanism 94 includes a first driving motor 941 and a translation screw 942. The first driving motor 941 is mounted on the first side plate 912, the driving shaft of the first driving motor 941 is passed through the first side plate 912, and a driving synchronous wheel 943 is installed at the end of the driving shaft.

[0204] In some embodiments, the translation screw 942 and the positioning plate 921 can be connected through a screw nut 944, the first end of the translation screw 942 is mounted on the second side plate 913, the second end of the translation screw 942 is inserted into the first side plate 912, and a driven synchronous wheel 945 is installed on the second end of the translation screw 942. The driving synchronous wheel 943 and the driven synchronous wheel 945 are connected through a transmission belt 946 to rotate under the drive of the first driving motor 941. The first driving motor 941 is a servo motor.

[0205] For example Fig.35 As shown, in some embodiments, the first bracket 91 is provided with a pair of slide rails 914; the receiving mechanism 93 includes a support plate 931, and both ends of the support plate 931 are connected to the slide rails 914 through sliding blocks 932. The receiving mechanism 93 also includes a driving assembly 933 connected to the support plate 931 to drive the support plate 931 to move up and down.

[0206] For example Fig.36 As shown, in some embodiments, the drive assembly 933 includes a mounting seat 9331 , a second drive motor 9332 , and a ball screw 9333 .

[0207] Read also Fig.38 , Fig.38 : is a side view of the residual material collecting device 9, the mounting seat 9331 is fixedly arranged at the lower position of the support plate 931, the second drive motor 9332 is mounted on the mounting seat 9331, and one end of the ball screw 9333 is mounted on the mounting seat 9331 and connected to the second drive motor 9332. The screw nut of the ball screw 9333 is connected to the support plate 931 to drive the support plate 931 to move up and down under the drive of the second drive motor 9332. In some embodiments, the second drive motor 9332 and the ball screw 9333 can be connected through a synchronous wheel assembly, which can refer to the form of the above-mentioned drive mechanism 92, and will not be described in detail here.

[0208] The support plate 931 may be a flat plate structure or a cylindrical structure. In some embodiments, the support plate 931 is a cylindrical structure, which ensures that when the remaining material of the third type of film material 300 is placed in the support plate 931, it will not be separated from the support plate 931 due to factors such as vibration or wind. The second drive motor 9332 is a servo motor.

[0209] In some embodiments, the waste material collection device 9 further includes a position sensor for monitoring the position of the waste material of the third type of film material 300 on the pallet 931. The position sensor can be arranged below the pallet 931. When the position sensor senses, the driving component 933 drives the pallet 931 to descend.

[0210] The first driving motor 941 and the second driving motor 9332 can be connected to the PLC industrial control computer to achieve automatic operation. Alternatively, the first driving motor 941 and the second driving motor 9332 are respectively configured with controllers.

[0211] During the working process, the conveyor belt 52 conveys the cut third type of film material 300 such as highly absorbent non-woven fabric and its waste material together to the lower part of the suction mechanism 92. The air cylinder 923 drives the suction cup 924 downward to suck up the waste material. At the same time, the air cylinder 923 returns to its original position. The first driving motor 941 drives the translation lead screw 942, and the translation lead screw 942 drives the suction mechanism 92 to move above the pallet 931. The air cylinder 923 acts, and the suction cup 924 moves downward. After putting down the waste material onto the pallet 931, it returns to its original position. The first driving motor 941 acts in the reverse direction again, driving the translation lead screw 942 to drive the air cylinder 923 back to the working position. When the waste material on the pallet 931 reaches a certain value, the second driving motor 9332 will automatically drive the ball screw 9333 to drive the pallet 931 to descend to the corresponding position. After reaching the lowest point, an alarm will be issued (which can be issued by the controller or the industrial control computer). After the operator takes away the waste material, the pallet 931 automatically rises to the high-position working state under the drive of the second driving motor 9332.

[0212] It can be seen from this that the waste material collection device 9 can collect the waste material after punching the third type of film material 300, thereby avoiding waste of raw materials. At the same time, compared with manual collection of waste materials, its efficiency is higher, and the production and manufacturing costs can be effectively reduced.

[0213] For another example Fig.34 , if the third type of film material 300 is a flexible material (such as highly absorbent non-woven fabric), after punching, the film materials left on both sides of the punching are not much, and it is very difficult to rely on its own strength and rigidity to convey the punched film material forward. There may be problems in the conveying quality (such as wrinkling, longitudinal stretching and transverse contraction, deviation, etc.) due to uneven force during the conveying process.

[0214] To this end, in some embodiments, in order to improve the conveying quality, as Figure 2 and Fig.25 shown, the film material processing and manufacturing equipment further includes a first delivery and cutting device 6 arranged adjacent to the first punching device 5 to solve the above problems.

[0215] Refer to 39 to Fig.41 , Fig.39Schematic perspective view of the first delivery and cutting device 6 Fig.40 Top view of the first delivery and cutting device 6 Fig.41 Side view of the first delivery and cutting device 6, the first delivery and cutting device 6 comprising:

[0216] A second bracket 61, which may be mounted on the frame 51 or may be considered as part of the frame 51;

[0217] An attracting mechanism 62, mounted on the second bracket 61 or the frame 51 and located above the conveyor belt 52, for attracting a first portion of the third type of film material 300;

[0218] A clamping mechanism 63, mounted on the second bracket 61 or the frame 51, for clamping a second portion of the third type of film material 300 and a portion of the conveyor belt 52 opposite to the second portion, and cooperating with the attracting mechanism 62 to deliver the third type of film material 300 to a predetermined position under the movement of the conveyor belt 52.

[0219] For example, the uncut third type of film material 300 is conveyed to position a, the attracting mechanism 62 returns to the initial position, and then the cutting mechanism 65 cuts the third type of film material 300. The cut single-piece third type of film material 300 is then continuously driven and conveyed by the conveyor belt of the downstream device such as the second heat-sealing device 7, such as being conveyed to the second heat-sealing device 7 for heat-sealing processing. The attracting mechanism 62 returns to the initial position, and its attracting member 625 presses on the third type of film material 300 near the cutting point at approximately Fig.39 the position b shown.

[0220] Another example Fig.39 As shown, in some embodiments, the first delivery and cutting device 6 further comprises:

[0221] A driving mechanism 64, disposed on the second bracket 61 or the frame 51 and connected to the attracting mechanism 62 and the clamping mechanism 63, for driving the attracting mechanism 62 and the clamping mechanism 63 to move together.

[0222] Please refer to Fig.42 , Fig.42 An enlarged schematic view of a partial structure of the first delivery and cutting device 6. As shown in the figure, the driving mechanism 64 includes two guide rails 641, two sliders 642, a fixing plate 643 and a driving assembly 644; the two guide rails 641 are disposed on opposite sides of the second bracket 61, the two sliders 642 are respectively movably mounted on the two guide rails 641, the fixing plate 643 connects the two sliders 642, the attracting mechanism 62 and the clamping mechanism 63 are mounted on the fixing plate 643, and the driving assembly 644 is connected to the fixing plate 643 to drive the fixing plate 643 to move back and forth along the guide rails 641.

[0223] Further, the driving assembly 644 includes two first synchronous pulley assemblies respectively mounted on the second bracket 61; each first synchronous pulley assembly includes two first synchronous pulleys 6441 spaced along the length direction of a guide rail 641, and a first synchronous belt 6442 connecting the two first synchronous pulleys 6441. The two first synchronous pulleys 6441 of the two relatively arranged first synchronous pulley assemblies are connected by a connecting shaft 6443, and the first synchronous belt 6442 is connected to the fixing plate 643.

[0224] Refer to Fig.43 , Fig.43 for Fig.42 a partially enlarged schematic view of the structure shown in the figure. As shown in the figure, the driving assembly 644 may further include a two-axis powder clutch 6444 and a fourth driving member 6445. One end of the two-axis powder clutch 6444 is connected to a first synchronous pulley 6441, and the other end of the two-axis powder clutch 6444 is connected to a second synchronous pulley 6446. The output end of the fourth driving member 6445 is connected with a third synchronous pulley 6447, and the second synchronous pulley 6446 and the third synchronous pulley 6447 are connected by a second synchronous belt 6448.

[0225] Wherein, the fourth driving member 6445 drives the third synchronous pulley 6447 to rotate, so that the second synchronous pulley 6446 rotates, and then drives the first synchronous pulley assembly to work, so that the attracting mechanism 62 and the clamping mechanism 63 move together.

[0226] Again, Fig.42 as shown in the figure, in some embodiments, the attracting mechanism 62 includes a mounting base 621, a mounting shaft 622, a swinging cylinder 623, a second swing rod 624, an attracting member 625 and a fifth driving member 626; there are two mounting bases 621, and the two mounting bases 621 are respectively arranged at both ends of the fixing plate 643 or on the slider 642; the swinging cylinder 623 is sleeved on the mounting shaft 622, and both ends of the mounting shaft 622 are respectively mounted on the two mounting bases 621; one end of the second swing rod 624 is fixedly connected to the swinging cylinder 623, and the attracting member 625 is connected to the end of the second swing rod 624 far away from the swinging cylinder 623; there may be two second swing rods 624, and each second swing rod 624 is arranged at one end of a swinging cylinder 623 far away from the other swinging cylinder 623.

[0227] The attracting member 625 is in a long strip structure, and its length direction is perpendicular to the moving direction of the third type of film material 300. Both ends of the attracting member 625 in the length direction are connected to the opposite surfaces of the two second swing rods 624, and may be detachably connected, such as by a threaded connection method. In some embodiments, the attracting member 625 is a needle-type suction cup.

[0228] Refer to Fig.44 and Fig.45 , Fig.44is Fig.43 a partially enlarged schematic view of the structure shown Fig.45 is Fig.42 another partially enlarged schematic view of the structure shown. As shown in the figure, the fifth driving member 626 is connected to the swing cylinder 623 and is used to drive the swing cylinder 623 to rotate so as to drive the attracting member 625 to move upward or downward, so that the attracting member 625 attracts a part of the third type of film material 300 or releases and moves away from the third type of film material 300.

[0229] In some embodiments, the attracting mechanism 62 includes a mounting plate 627 mounted on the fixing plate 643, and the mounting plate 627 can be mounted at the middle position of the fixing plate 643.

[0230] Again Fig.44 as shown, the fifth driving member 626 is mounted on the mounting plate 627, and the output end of the fifth driving member 626 is connected to the connecting portion of the swing cylinder 623 through a ring head member 628. Each swing cylinder 623 is provided with a plate-shaped connecting portion 6231 near the position of another swing cylinder 623, and through holes are provided at the ends of the two connecting portions 6231 far away from the swing cylinder 623. The ring portion of the ring head member 628 extends between the two connecting portions 6231, and a rotating shaft passes through the through hole and the ring portion to connect the connecting portion 6231 with the ring head member 628, and then connects the fifth driving member 626 with the swing cylinder 623 together.

[0231] The fifth driving member 626 can be a driving motor or a cylinder. In some embodiments, when a driving motor is adopted, the driving motor can be connected to the swing cylinder 623 through a lead screw transmission assembly.

[0232] Again Fig.42 as shown, in some embodiments, the clamping mechanism 63 includes a positioning plate 631 connected to the fixing plate 643 and a stop block 632 connected to one end of the positioning plate 631 far away from the fixing plate 643. The stop block 632 is located below the upper part of the conveyor belt 52. The positioning plate 631 can be one or two; when two are provided, the two positioning plates 631 are connected to one end of the fixing plate 643 close to the inner side of the guide rail 641. The stop block 632 is in a long strip structure, and its inner surface facing the conveyor belt 52 can be a flat structure to ensure sufficient contact area. In some embodiments, the length direction of the stop block 632 is perpendicular to the moving direction of the third type of film material 300.

[0233] Again Fig.45 as shown, in some embodiments, the clamping mechanism 63 further includes a sixth driving member 633 connected to the fixing plate 643, and a pressing block 634 is connected to the output end of the sixth driving member 633. The pressing block 634 is located above the third type of film material 300, and the sixth driving member 633 is used to drive the pressing block 634 to move up and down.

[0234] During the working process, the sixth driving member 633 drives the pressing block 634 to move downward, so as to cooperate with the stop block 632 to clamp and fix the third type of film material 300 and a part of the conveyor belt 52 opposite thereto together, so that the third type of film material 300 can move along with the conveyor belt 52. When the sixth driving member 633 drives the pressing block 634 to move upward away from the third type of film material 300, the clamping mechanism 63 returns to its original position.

[0235] For another example Fig.39 As shown, in some embodiments, the first delivery and cutting device 6 further includes a cutting mechanism 65 for cutting the third type of film material 300.

[0236] Refer to Figures 46 to 51 , Fig.46 which is another partial enlarged schematic view of the first delivery and cutting device 6, Fig.47 is Fig.46 a partial enlarged schematic view of the circled part of the structure shown, Fig.48 is Fig.46 a three-dimensional structure schematic view of the structure shown from another perspective, Fig.49 is Fig.46 a three-dimensional structure schematic view of the cutting mechanism 65 shown, Fig.50 is Fig.49 a partial structure schematic view of the cutting mechanism 65 shown, Fig.51 is Fig.50 a partial enlarged view of the circled part of the cutting mechanism 65 shown.

[0237] As Fig.46 shown, the cutting mechanism 65 includes a cutting track 651 provided on the second bracket 61, two second synchronous wheel assemblies 652 provided on both sides of the second bracket 61 and located in the length direction of the cutting track 651 (as Fig.48 shown), and a third synchronous belt 6523 connecting the two second synchronous wheel assemblies 652.

[0238] As Fig.49 shown, each second synchronous wheel assembly 652 includes a fixed seat 6521 and two fourth synchronous wheels 6522 mounted on the fixed seat 6521. The two fourth synchronous wheels 6522 are spaced apart in the up-down direction, and the third synchronous belt 6523 connects the four fourth synchronous wheels 6522.

[0239] For another example Fig.46 shown, the cutting mechanism 65 further includes a seventh driving member 653. The output end of the seventh driving member 653 is connected with a fifth synchronous wheel 654, and one of the fourth synchronous wheels 6522 is connected with a sixth synchronous wheel 655. The fifth synchronous wheel 654 and the sixth synchronous wheel 655 are connected by a fourth synchronous belt 656.

[0240] Further, the cutting mechanism 65 further includes a cutting assembly 657 connected to the third synchronous belt 6523 (such as Fig.48 shown).

[0241] Another example is Fig.49 shown. The seventh driving member 653 drives the second synchronous wheel assembly 652 to rotate, so as to drive the cutting assembly 657 to move along the cutting track 651 to cut the third type of film material 300. In some embodiments, the seventh driving member 653 can be a servo motor.

[0242] In some embodiments, the cutting assembly 657 includes a base 6571 connected to the third synchronous belt 6523 and a cutting tool holder 6572 provided on the base 6571. A cutting tool 6573 is provided on the cutting tool holder 6572. The cutting assembly 657 further includes an eighth driving member 6574 connected to the cutting tool 6573 to drive the cutting tool 6573 to rotate. The eighth driving member 6574 is a servo motor.

[0243] During the working process, the seventh driving member 653 and the eighth driving member 6574 cooperate with each other to ensure that the advancing speed of the cutting assembly 657 matches the tangential speed at the cutting edge of the cutting tool 6573. The tangential speed at the cutting edge of the cutting tool 6573 is slightly greater than or equal to the advancing speed of the cutting assembly 657, which is beneficial to ensuring their cutting quality.

[0244] Another example is Fig.46 shown. A moving channel 6511 is provided on the cutting track 651 along its length direction. The upper part of the base 6571 and the third synchronous belt 6523 can be placed in the moving channel 6511, and the moving channel 6511 can provide a moving guiding space for the base 6571 and the third synchronous belt 6523.

[0245] Referring together to Figures 49 to 51 , the base 6571 can be a plate-like structure. The cutting tool holder 6572 is connected to the base 6571 through a support member 65711. A cutting groove 65712 is provided on the base 6571. The cutting tool 6573 is disposed opposite to the cutting groove 65712, and the lower end of the cutting tool 6573 can extend into the cutting groove 65712. A pulley assembly 65713 can also be provided on the base 6571, so that the resistance is smaller when the base 6571 contacts the cutting track 651.

[0246] Another example is Fig.39 shown. In some embodiments, the first feeding and cutting device 6 further includes a cutting frame 66 installed on the second bracket 61. Referring together to Fig.46The cutting frame 66 may include a lower beam 661, an upper beam 662 and a support beam 663. The lower beam 661 and the upper beam 662 are arranged opposite to each other at intervals, and the support beam 663 is connected between the lower beam 661 and the upper beam 662. There may be a plurality of support beams 663, and the upper beam 662 may be mounted to the upper end of the support beam 663 through a fixing member, and the cutting track 651 may be arranged on the lower beam 661.

[0247] For example Fig.49 and Fig.50 As shown, the cutting mechanism 65 also includes a guide rod 658 disposed on the cutting frame 66 and parallel to the cutting track 651 , and a guide member 659 is provided on the guide rod 658 which can move axially along the guide rod 658 , and the guide member is connected to the cutting knife seat 6572 through a connecting member 6510 .

[0248] During operation, the third type of film material 300 is located on the cutting track 651, and the suction member 625 of the suction mechanism 62 presses the third type of film material 300 onto the cutting track 651. The seventh driving member 653 and the eighth driving member 6574 start and run at a certain proportional speed at the same time. The seventh driving member 653 drives the fourth synchronous belt 656, and the fourth synchronous belt 656 drives the third synchronous belt 6523 to move. The third synchronous belt 6523 drives the cutting assembly 657 to move on the cutting track 651. At the same time, the eighth driving member 6574 drives the cutting knife 6573 to rotate and cut. After the third type of film material 300 is cut horizontally, the seventh driving member 653 moves in the opposite direction, driving the cutting assembly 657 back to the original position or initial position to prepare for the next working cycle. The third type of film material 300 cut into single pieces is conveyed to the second heat sealing device 7 by the conveyor belt of the second heat sealing device 7, and the heat sealing process is performed at the second heat sealing device 7. The conveyor belt of the second heat sealing device 7 and the conveyor belt 52 can be driven by respective driving mechanisms.

[0249] Furthermore, after the cutting assembly 657 returns to the initial position, the suction member 625 sucks the third type of film material 300 and lifts it up, and the clamping mechanism 63 at the back clamps the third type of film material 300 and the corresponding part of the conveyor belt 52 together (at this time, the dual-axis powder clutch 6444 is powered off), and the conveyor belt 52 sends the third type of film material 300 forward, while sending the suction mechanism 62 and the clamping mechanism 63 forward together. Fig.39At the position a shown, the conveyor belt 52 stops, the attracting member 625 touches the conveyor belt of the second heat-sealing device 7 downward, releases the third type of film material 300 and then lifts up. The clamping mechanism 63 opens, that is, the stopper 632 and the pressing block 634 are separated. The conveyor belt 52 does not move. The attracting mechanism 62 and the clamping mechanism 63 are driven by the driving mechanism 64 (at this time, the two-shaft powder clutch 6444 is electrified) and return to the starting position, that is, the attracting member 625 is at the cutting track 651 position and presses down to fix the third type of film material 300 (the front end of the attracting member 625 is at Fig.39 the position b shown), facilitating the cutting assembly 657 to cut the third type of film material 300.

[0250] As can be seen from the above, the third type of film material 300 can be completely supported and conveyed by the conveyor belt 52, avoiding the influence on the conveying quality (such as wrinkling, longitudinal stretching and transverse contraction, deviation, etc.) of the third type of film material 300 due to uneven force during the conveying process. At the same time, the cutting mechanism 65 uses a combination of two driving members (such as two servos) to control the cutting, and the advantage is that no or significantly less burrs are generated.

[0251] For another example Figure 2 and Fig.25 shown, in some embodiments, the second heat-sealing device 7 is respectively adjacent to the cutting mechanism 65 and the first heat-sealing device 3 or the corona device 15, and is used to thermally combine the third type of film material unit with the first assembly 400 into the second assembly 500.

[0252] Refer to Fig.52 and Fig.53 , Fig.52 which is a three-dimensional structure schematic diagram of the second heat-sealing device 7, Fig.53 and

[0253] is a side view of the second heat-sealing device 7. As shown in the figure, the second heat-sealing device 7 includes a third bracket 71, and the third bracket 71 can be a part of the frame 51 or an independently arranged frame structure.

[0254] The second heat-sealing device 7 further includes a first conveying mechanism 72 installed on the third bracket 71 for conveying the third film material unit and a second conveying mechanism 73 installed on the third bracket 71 for conveying the first assembly 400. The first conveying mechanism 72 and the second conveying mechanism 73 are arranged at intervals. Fig.53 shown

[0255] Refer to together Fig.54 , Fig.54It is a cross-sectional view of the second heat-sealing device 7 in the horizontal direction. As shown in the figure, during the working process, the first conveying mechanism 72 sends the third film unit cut in the previous process to the exact position below the picking mechanism 75, and the second conveying mechanism 73 conveys the part of the first assembly 400 that needs to be heat-sealed with the reinforcement sheet (the part that needs to be heat-sealed with the third film unit) to the position below the heat-sealing mechanism 74. The picking mechanism 75 picks up the third type of film unit, translates and places it on the part to be heat-sealed of the first assembly 400, and then moves back to the initial position, that is, above the first conveying mechanism 72. At this time, the heat-sealing mechanism 74 moves downward to heat-seal the third type of film unit and the first assembly 400 together to form the second assembly 500. Then the heat-sealing mechanism 74 moves upward and resets to the initial position. At this time, the second conveying mechanism 73 conveys the assembly to the next process equipment, and the second heat-sealing device 7 circulates to perform the heat-sealing process.

[0256] The third type of film unit can be a cut strong water-absorbent non-woven fabric, and the first assembly 400 can be an assembly formed by heat-sealing transparent PE (A single) and non-tearable PE (B single).

[0257] Again, Fig.52 As shown, in some embodiments, a frame body 711 is further provided on the third support 71, and two guide rails 712 are oppositely provided on the frame body 711. The picking mechanism 75 is movably installed on the two guide rails 712 through at least one moving mechanism 76, so that during the working process, driven by the moving mechanism 76, the picking mechanism 75 moves from above the first conveying mechanism 72 to above the second conveying mechanism 73.

[0258] The frame body 711 may include two first mounting beams 7111, two second mounting beams 7112, two front beams 7113 and two rear beams 7114. The two first mounting beams 7111 are arranged relatively parallel, and the two second mounting beams 7112 are arranged relatively parallel and both extend from above the first conveying mechanism 72 to above the second conveying mechanism 73. The two second mounting beams 7112 are arranged above the two first mounting beams 7111, and one first mounting beam 7111 is correspondingly arranged with one second mounting beam 7112. The two ends of the two first mounting beams 7111 and the two second mounting beams 7112 are respectively connected to the two front beams 7113 and the two rear beams 7114. The aforementioned guide rails 712 may be provided on the first mounting beam 7111.

[0259] In some embodiments, the moving mechanism 76 can be set to one or two. Referring together Fig.55 and Fig.56 , Fig.55 It is a partial structural schematic diagram of the second heat-sealing device 7, Fig.56 is Fig.55Side view of the structure shown. As shown in the figure, the moving mechanism 76 includes two connecting plates 761. A slider that can be movably installed on a guide rail 712 is provided at the lower end of each connecting plate 761. The picking mechanism 75 is connected to the two connecting plates 761.

[0260] Again, Fig.56 As shown, the moving mechanism 76 may further include at least one driving motor 763 and a transmission lead screw 764 connected to the driving motor 763. The driving motor 763 is fixed on the frame body 711. The part of the transmission lead screw 764 close to the driving motor 763 is connected to the connecting plate 761 through a lead screw seat 765. One end of the transmission lead screw 764 far from the driving motor 763 is installed on one side of the frame body 711 close to the heat sealing mechanism 74. The driving motor 763 can drive the transmission lead screw 764 to rotate to drive the picking mechanism 75 to move back and forth.

[0261] Again, Fig.55 As shown, in some embodiments, the picking mechanism 75 includes two cross beams 751, a first mounting plate 752, a ninth driving member 753, and a suction member 754. The two cross beams 751 are arranged oppositely and are respectively connected to the two connecting plates 761. The first mounting plate 752 is respectively connected to the two cross beams 751. The ninth driving member 753 is installed on the first mounting plate 752 and the output end of the ninth driving member 753 is connected to the suction member 754 to drive the suction member 754 to move up and down. The ninth driving member 753 can be a driving device such as a driving motor, a hydraulic cylinder, or a pneumatic cylinder. The suction member 754 can adopt a needle type suction cup or a vacuum suction cup.

[0262] In some embodiments, the picking mechanism 75 further includes at least two first guiding assemblies. Each first guiding assembly includes a first fixing plate 755, a first linear bearing 756, and a first guiding shaft 757. The first fixing plate 755 is respectively connected to the two cross beams 751. The first linear bearing 756 is installed on the first fixing plate 755. The first guiding shaft 757 passes through the first linear bearing 756 and is vertically connected to the suction member 754.

[0263] Again, Fig.55 As shown, in some embodiments, the heat sealing mechanism 74 includes a second mounting plate 741, a tenth driving member 742, and a heat sealing member 743. The second mounting plate 741 is installed on the third bracket 71, and the second mounting plate 741 is located above the moving mechanism 76 in the height direction. The tenth driving member 742 is installed on the second mounting plate 741 and the output end of the tenth driving member 742 is connected to the heat sealing member 743 to drive the heat sealing member 743 to move up and down. When the heat sealing member 743 presses the third film material unit and the first assembly 400, it heat seals the third film material unit and the first assembly 400.

[0264] In some embodiments, the heat-sealing member 743 may be a disc structure or a plate structure. The heat-sealing member 743 has at least one of a heating wire, a heating tube, or a heating sheet, and can instantaneously generate heat to heat-seal the third type of film unit and the first assembly 400.

[0265] Referring together Fig.55 and Fig.56 , the heat-sealing mechanism 74 may further include at least two second guiding components. Each second guiding component includes a second fixing plate 744, a second linear bearing 745, and a second guiding shaft 746. The second fixing plate 744 is respectively connected to two third brackets 71. The second linear bearing 745 is installed on the second fixing plate 744, and the second guiding shaft 746 passes through the second linear bearing 745 and is vertically connected to the heat-sealing member 743.

[0266] A plurality of the second guiding components may be provided, and the plurality of second guiding components may be evenly distributed on both sides of the tenth driving member 742, playing a guiding role, and enabling the tenth driving member 742 to drive the heat-sealing member 743 to move up and down more smoothly and stably.

[0267] For another example Fig.53 as shown, the first conveying mechanism 72 may include a conveyor belt 721 for carrying the third film unit and a driving mechanism 722 that cooperates with the conveyor belt 721 to drive the conveyor belt 721 to rotate to convey the third film unit to below the picking mechanism 75. The third frame body 711 has a first working platform 713. The first working platform 713 is arranged below the picking mechanism 75. The conveyor belt 721 can be wound around the outer periphery of the first working platform 713. The driving mechanism 722 may be a driving mechanism of a roller cooperating with a motor, and the form of the driving mechanism 722 may have various forms, which are not specifically limited here.

[0268] For another example Fig.52 as shown, the part of the third bracket 71 located on the conveying path of the first assembly 400 is divided into a first side and a second side, and the first side and the second side are arranged oppositely. The third bracket 71 has a second working platform 714. The second working platform 714 is located below the heat-sealing mechanism 74. The side of the second working platform 714 away from the first conveying mechanism 72 is the above-mentioned first side, and the side of the second working platform 714 facing the first conveying mechanism 72 is the above-mentioned second side.

[0269] Referring together Fig.56 , the second conveying mechanism 73 may include a first roller 731, a second flattening roller 732, a second roller 733, a driving roller assembly 734 (such as Fig.52As shown). The first roller 731 and the driving roller assembly 734 are located on the aforementioned first side, and the driving roller assembly 734 is located above the first roller 731; the second flattening roller 732 and the second roller 733 are located on the aforementioned second side, and the second roller 733 is located above the second flattening roller 732.

[0270] The first roller 731 and the second flattening roller 732 can be at the same horizontal height, and the second roller 733 and the driving roller assembly 734 are at the same horizontal height; in some embodiments, the first roller 731 and the second flattening roller 732 do not necessarily need to be at the same horizontal height, and the second roller 733 and the driving roller assembly 734 do not necessarily need to be at the same horizontal height either. Their positions can be appropriately adjusted according to actual needs and are not specifically limited here.

[0271] During the working process, the first assembly 400 is sequentially conveyed through the first roller 731, the flattening roller 732, the second roller 733, and the driving roller assembly 734. When the first assembly 400 is located between the second roller 733 and the driving roller assembly 734, the portion to be heat-sealed of the first assembly 400 is disposed opposite to the heat-sealing mechanism 74. Among them, the portion to be heat-sealed of the first assembly 400 is the back surface of the first assembly 400. After being conveyed through the first roller 731, the second flattening roller 732, the second roller 733, and the driving roller assembly 734, when the first assembly 400 is located below the heat-sealing mechanism 74, the side of the first assembly 400 facing the heat-sealing mechanism 74 is the back surface of the first assembly 400.

[0272] Again, Fig.56 As shown, the driving roller assembly 734 may include a third roller 7341, a driving roller 7342, and a driving component 7343. The third roller 7341 and the driving roller 7342 are at the same horizontal height and a gap is formed between them for the heat-sealed second assembly 500 to pass through. The driving component 7343 is connected to the driving roller 7342 to drive the driving roller 7342 to rotate. The driving component 7343 may include a driving motor, a first synchronous pulley, a second synchronous pulley, and a synchronous belt. The output end of the driving motor is connected to the first synchronous pulley, the second synchronous pulley is connected to the driving roller 7342, and the synchronous belt is respectively connected to the first synchronous pulley and the second synchronous pulley. The output end of the driving motor drives the first synchronous pulley to rotate to drive the driving roller 7432 to rotate.

[0273] During the working process, the heat-sealed second assembly 500 passes through the upper circumferential surface of the driving roller 7342, enters the gap, and is conveyed upward from the lower side of the gap through the lower circumferential surface of the third roller 7341 to the downstream process device such as the first gluing device 81.

[0274] The second heat-sealing device 7 may also be configured with relevant sensors to detect the position states of mechanisms such as the heat-sealing mechanism 74 and the picking mechanism 75, as well as the working state of the conveying mechanism, etc. The drive motor, drive components, etc. can be controlled by an industrial control computer such as a PLC industrial control computer.

[0275] Combined with Fig.57 as shown, Fig.57 FIG. is a simplified application diagram of the second heat-sealing device 7. The working principle of the second heat-sealing device 7 is as follows:

[0276] Initial state: The picking mechanism 75 is at the original position above the first working platform, and the heat-sealing mechanism 74 is at the original position above the second working platform. The conveyor belt 721 conveys the previously cut third film material unit, such as a highly absorbent non-woven fabric, to the lower part of the picking mechanism 75. The picking mechanism 75 sucks down the third film material unit and returns. Driven by the moving mechanism 76, it translates to the right to the lower part of the heat-sealing mechanism 74 and places the third film material unit at the first assembly 400. The picking mechanism 75 lifts and returns to the original position. The heat-sealing mechanism 74 presses down, pressing the third film material unit and the first assembly 400. At this time, the heating wire installed on the heat-sealing mechanism 74 instantaneously heats up to heat-seal the third film material unit and the first assembly 400. The heat-sealing mechanism 74 rises back to the original position, preparing for the next action cycle.

[0277] As can be seen from the above, the second heat-sealing device 7 can automate the heat-sealing of the third type of film material unit and the first assembly 400. Compared with the manual heat-sealing method, it can effectively improve production efficiency and maintain the consistency of product quality.

[0278] Again, for example Figure 2 as shown, in some embodiments, the processing device 8 includes a first gluing device 81; the first gluing device 81 is located above the second heat-sealing device 7 and is close to the corona device 15 or the first heat-sealing device 3 for gluing the first type of glue 600 to the second assembly 500 (such as Fig.58 as shown).

[0279] Referring to Figures 58 to 60 , Fig.58 FIG. is a three-dimensional structure diagram of the first gluing device 81, Fig.59 FIG. is a three-dimensional structure diagram of the first gluing device 81 from another perspective, Fig.60 FIG. is an application diagram of the first gluing device 81. As shown in the figure, the first gluing device 81 may include: a fourth bracket 811, a conveying mechanism 812 provided on the fourth bracket 811 for conveying the second assembly 500, and a gluing device 813 provided on the fourth bracket 811 and located above the conveying mechanism 812 for gluing the second assembly 500.

[0280] Referring together to Fig.61 and Fig.62, Fig.61 It is a schematic three-dimensional structure diagram of the glue pasting device 813. Fig.62 It is a schematic three-dimensional structure diagram of the glue pasting device 813 from another perspective. The glue pasting device 813 includes a second mounting bracket 8131 (as shown in Fig.58 ), a glue supply mechanism 8132 provided on the second mounting bracket 8131 for supplying the first type of glue 600, a glue feeding mechanism 8133 provided on the second mounting bracket 8131 for conveying the first type of glue 600, and a glue pasting mechanism 8134 provided on the second mounting bracket 8131 and adjacent to the glue feeding mechanism 8133 for cutting the first type of glue 600 conveyed by the glue feeding mechanism 8133 and pasting the cut glue units on the second assembly 500 (as shown in Fig.62 ).

[0281] Again, as shown in Fig.59 , in some embodiments, the second mounting bracket 8131 includes a mounting plate 81311, and the glue supply mechanism 8132 is provided on the mounting plate 81311. The glue supply mechanism 8132 includes a mounting component, and the mounting component includes a mounting shaft 81321, a powder clutch 81322, and a bearing seat 81323. The mounting shaft 81321 is inserted through the bearing seat 81323, and the first end of the mounting shaft 81321 is connected to the powder clutch 81322, and the second end of the mounting shaft 81321 is for mounting the first type of glue 600. In some embodiments, the mounting shaft 81321 can be an air shaft.

[0282] Again, as shown in Fig.62 , the glue supply mechanism 8132 may further include a positioning plate 81324, and the mounting component is provided on the positioning plate 81324. The glue supply mechanism 8132 may further include a deviation rectifying component. The deviation rectifying component includes a first slide rail group 81325, an eleventh driving member 83126, and a first connecting block 81327. The first slide rail group 81325 connects the positioning plate 81324 and the mounting plate 81311. The eleventh driving member 83126 is connected to the positioning plate 81324 through the first connecting block 81327 to drive the positioning plate 81324 to move in the deviation rectifying direction to adjust the position of the first type of glue 600. The deviation rectifying direction may be perpendicular to the conveying direction of the second assembly 500. The first slide rail group 81325 can be a combination of a guide rail and a guide block. For example, the mounting plate 81311 is provided with a guide rail, and the lower side surface of the positioning plate 81324 is provided with a guide block, and the guide block is movably fitted on the guide rail. The eleventh driving member 83126 can be a servo motor.

[0283] The second mounting bracket 8131 may further include a support bracket 81312. The glue feeding mechanism 8133 includes a first idler wheel 81331, a second idler wheel 81332, a third idler wheel 81333, a fourth idler wheel 81334, a driving roller 81335, a first driven roller 81336, a conveyor belt 81337 and a twelfth driving member 81338 disposed on the support bracket 81312. The first idler wheel 81331, the second idler wheel 81332 and the third idler wheel 81333 are arranged side by side at intervals to form an idler wheel group, and the first idler wheel 81331 is disposed close to the glue feeding mechanism 8132, and the fourth idler wheel 81334 is disposed below the third idler wheel 81333.

[0284] Refer to Fig.63 , Fig.63 FIG. is a schematic perspective view of the glue feeding mechanism 8133. As shown in the figure, the conveyor belt 81337 is respectively wound around the driving roller 81335 and the first driven roller 81336, and the driving roller 81335 is disposed on the side close to the fourth idler wheel 81334. The first driven roller 81336 is disposed on the side close to the glue pasting mechanism 8134. The twelfth driving member 81338 is connected to the driving roller 81335 to drive the driving roller 81335 to rotate, thereby driving the conveyor belt 81337 to convey the first type of glue 600.

[0285] During the working process, the first type of glue 600 on the glue feeding mechanism 8132 passes through the gap between the first idler wheel 81331 and the second idler wheel 81332, winds around the second idler wheel 81332 from the gap between the second idler wheel 81332 and the third idler wheel 81333 upwards around the third idler wheel 81333, and then winds around the fourth idler wheel 81334 downwards from the third idler wheel 81333 and enters the conveyor belt 81337.

[0286] Again, as Fig.61 shown, in some embodiments, the glue pasting device 813 further includes a paper collecting mechanism 8135 mounted on the second mounting bracket 8131 and located above the conveyor belt 81337 for winding up the separator paper of the first type of glue 600. Refer to Fig.62, the sheet receiving mechanism 8135 includes a receiving shaft 81351 and a thirteenth driving member 81352 connected to the receiving shaft 81351 for driving the rotation of the receiving shaft 81351. One end of the receiving shaft 81351 away from the thirteenth driving member 81352 can be located above the conveyor belt 81337. During operation, an operator can first fix one end of the release paper on the first rubber material 600 to the receiving shaft 81351. During the conveying process of the first rubber material 600, when it is on the conveyor belt 81337, the receiving shaft 81351 rotates to wind the release paper on the first type of rubber 600 away from the first type of rubber 600, so that the adhesive surface of the first type of rubber 600 is exposed. The first type of rubber 600 with the release paper peeled off continues to be conveyed forward into the rubber pasting mechanism 8134.

[0287] Again, Fig.62 As shown, the sheet receiving mechanism 8135 further includes a pressing plate 81353 provided on the bracket 81312. The pressing plate 81353 can be inclined downward from the side away from the rubber pasting mechanism 8134 to the side close to the rubber pasting mechanism 8134. One end of the pressing plate 81353 abuts against the release paper of the first type of rubber 600 located on the conveyor belt 81337, so that the first type of rubber 600 after the release paper is peeled off is smoothly transported into the rubber pasting mechanism 8134.

[0288] Refer to Fig.64 and Fig.65 , Fig.64 is a schematic three-dimensional structure diagram of the rubber pasting mechanism 8134, Fig.65 is a partially enlarged view of the rubber pasting mechanism 8134. As shown in the figure, the rubber pasting mechanism 8134 includes an upper roller 81341, a lower roller 81342, a first shaft 81343, a second shaft 81344, a first gear 81345, a second gear 81346, a first synchronous pulley 81347, a second synchronous pulley 81348, a synchronous belt 81349, and a fourteenth driving member 813410. The upper roller 81341 and the lower roller 81342 are arranged oppositely, and the upper roller 81341 is directly above the lower roller 81342.

[0289] The first end of the first shaft 81343 is connected to the upper roller 81341. The second end of the first shaft 81343 is sleeved with a first gear 81345 and a first synchronous pulley 81347. The first end of the second shaft 81344 is connected to the lower roller 81342. The second end of the second shaft 81344 is sleeved with a second gear 81346. The first gear 81345 and the second gear 81346 are meshed with each other.

[0290] The output end of the fourteenth driving member 813410 is connected to the second synchronous pulley 81348, and the synchronous belt 81349 connects the first synchronous pulley 81347 and the second synchronous pulley 81348 to drive the upper roller 81341 and the lower roller 81342 to rotate under the drive of the fourteenth driving member 813410; the first type of glue 600 for peeling the release paper is conveyed to the lower roller 81342.

[0291] For another example Fig.65 As shown, a cutter 813411 for cutting the first type of glue 600 located on the outer periphery of the lower roller 81342 into glue material units is provided on the upper roller 81341; the lower roller 81342 is connected to a vacuum source (not shown) to attract the glue material units and attach the glue material units to the second assembly 500. The length of the glue material units is controlled by the driving servo 81338. In some embodiments, a vacuum chamber is formed inside the lower roller 81342, and suction holes are provided on the surface of the lower roller 81342 for sucking and releasing the first type of glue 600 or the glue material units.

[0292] For another example Fig.58 and Fig.59 As shown, the conveying mechanism 812 includes a first roller 8121, a second roller 8122, a conveyor belt 8123, and a fifteenth driving member 8124. The first roller 8121 is provided at the first end of the fourth bracket 811, the second roller 8122 is provided at the second end of the fourth bracket 811, the conveyor belt 8123 connects the first roller 8121 and the second roller 8122, and the fifteenth driving member 8124 is connected to the second roller 8122 to drive the second roller 8122 to rotate to drive the conveyor belt 8123 to move.

[0293] The first gluing device 81 further includes a tensioning mechanism 814 installed on the fourth bracket 811 and located below the conveyor belt 8123. The tensioning mechanism 814 includes a third roller 8141 (as Fig.59 shown), a third flattening roller 8142, a slider 8143, and a slide bar 8144. The third roller 8141 is provided at the first end of the fourth bracket 811 and below the first roller 8121. The number of slide bars 8144 is two. The two slide bars 8144 are arranged relatively spaced apart and are inclined downward from the first end of the fourth bracket 811 to the second end of the fourth bracket 811. The two ends of the third flattening roller 8142 are movably connected to the slide bars 8144 through the sliders 8143 respectively.

[0294] During the working process, the second assembly 500 first enters the third flattening roller 8142 from the third roller 8141, and then enters the conveyor belt 8123 from one side of the first roller 8121 by winding around the third flattening roller 8142 in the reverse direction. Referring to Fig.60 , the conveying sequence of the second assembly 500 is 500a - 500b - 500c - 500d - 500e. When the second assembly 500 is located below the gluing device 813, gluing operation is performed.

[0295] The third flattening roller 8142 mainly ensures the smoothness and flatness of the second assembly 500 during the conveying process. When the speed at the outlet (labeled 500e) of the second assembly 500 is greater than the speed at the inlet (labeled 500a), the length of the second assembly 500 from label 500c to label 500e will become shorter and shorter, and the third flattening roller 8142 will be lifted to the left to make up for the insufficient length of the second assembly 500; when the speed at the outlet (labeled 500e) is less than the speed at the inlet (labeled 500a), the length of the second assembly 500 from label 500c to label 500e will become longer and longer, and the third flattening roller 8142 will slide downward to the right along the sliding rod 8144 under its own weight to ensure that the second assembly 500 always has a certain tension.

[0296] The working principle of the first rubber pasting device 81 is as follows: The conveying mechanism 812 conveys the second assembly 500, such as the main sheet heat-sealed with a highly absorbent non-woven fabric. The first type of glue 600 on the glue material mechanism 8132 enters the glue pasting material mechanism 8134 through the glue feeding mechanism 8133, and is cut into appropriate size specifications of glue material units in the glue pasting material mechanism 8134, and is rotationally pasted onto the appropriate position of the second assembly 500 by the lower roller 81342. The product after pasting the glue (which can be defined as an assembly in some embodiments) continues to be conveyed forward to the next processing procedure device.

[0297] In some embodiments, when pasting the clip core glue and the horizontal glue for the tearable small sheet, the first rubber pasting device 81 can be configured with two, and the two first rubber pasting devices 81 are arranged at intervals. One first rubber pasting device 81 is used for pasting the clip core glue, and the other first rubber pasting device 81 is used for pasting the horizontal glue. Their principles are the same, and the first rubber pasting device 81 for the horizontal glue part does not need to collect the release paper, etc. This will not be elaborated here.

[0298] Again Figure 2 As shown, in some embodiments, the processing device 8 may further include a second rubber pasting device 82; the second rubber pasting device 82 is arranged adjacent to the first rubber pasting device 81 and is used for pasting the second type of glue 700 on part of the first type of film material 100 and / or part of the second type of film material 200 in the second assembly 500 that has already been pasted with the first type of glue 600.

[0299] Refer to Figure 66 to Figure 68 , Fig.66 is a three-dimensional structural schematic diagram of the second rubber pasting device 82, Fig.67 is a top view of the second rubber pasting device 82, Fig.68 is a side view of the second rubber pasting device 82. The second rubber pasting device 82 may include:

[0300] The fifth bracket 821;

[0301] A traction mechanism 822 installed on the fifth bracket 821 for conveying the second assembly 500 (the second assembly 500 that has been pasted with the first type of adhesive 600) into the device. The function of the traction mechanism 822 is to ensure the feeding of the second assembly 500 and synchronize with the length of the conveying mechanism 823;

[0302] A conveying mechanism 823 installed on the fifth bracket 821, and the conveying mechanism 823 is used to convey the second assembly 500; and

[0303] An adhesive pasting mechanism 824 installed on the fifth bracket 821 and located above the conveyor belt 8231 of the conveying mechanism 823.

[0304] Refer to together Figure 69 to Figure 71 , Fig.69 is a partial structural schematic diagram of the second adhesive pasting device 82, Fig.70 is a partial structural schematic diagram of the second adhesive pasting device 82 from another perspective, Fig.71 is Fig.70 As shown in the partial enlarged view of the second adhesive pasting device 82 shown, as shown in the figure, the traction mechanism 822 includes a first driving motor 8221, a first roller 8222, a second roller 8223, two slide rails 8224 and a flattening roller 8225. The first roller 8222 and the second roller 8223 are arranged at the first end of the fifth bracket 821. There is a certain gap between the first roller 8222 and the second roller 8223 as the inlet for the second assembly 500. The first driving motor 8221 can drive the first roller 8222 to rotate through mechanisms such as synchronous wheels and synchronous belts to traction the second assembly 500 to be transported forward. The two slide rails 8224 are relatively arranged on the fifth bracket 821 and are located below the conveyor belt 8231, and the two slide rails 8224 are inclined downward from the side close to the first roller 8222 to the side far from the first roller 8222. The flattening roller 8225 can be movably installed on the two slide rails 8224 through sliders.

[0305] During the working process, the second assembly 500 can first enter the second adhesive pasting device 82 from the gap between the first roller 8222 and the second roller 8223, and then go down around the flattening roller 8225 and then go up reversely onto the conveyor belt 8231, and the conveyor belt 8231 conveys the second assembly 500.

[0306] Combined with Fig.68 As shown, the flattening roller 8225 mainly ensures the stability and flatness of the second assembly 500 during the conveying process. The conveying sequence of the second assembly 500 is 500f - 500g - 500h - 500i - 500j - 500k. When the speed at the outlet of the second assembly 500 (as shown at the label 500k in the figure) is greater than the inlet (such as Fig.68When the speed at the label 500f), the length of the second assembly 500 from the label 500h to the label 500k will become shorter and shorter, and the flattening roller 8225 will be lifted to the right to make up for the shortage of the length of the second assembly 500; when the speed at the outlet (such as the label 500k) is less than the speed at the inlet (the label 500f), the length of the second assembly 500 from the label 500h to the label 500k will become longer and longer. Fig.68 Under the action of its own weight, the flattening roller 8225 in Fig.68 will slide downward to the left along the slide rail 8224 to ensure that the second assembly 500 always has a certain tension.

[0307] For another example Fig.70 As shown in Fig.70 , in some embodiments, the conveying mechanism 823 includes a conveyor belt 8231, a second driving motor 8232, a driving roller 8233 and a second driven roller 8234. The driving roller 8233 is arranged at the second end of the fifth bracket 821, and the second driven roller 8234 is arranged at the first end of the fifth bracket 821 and above the first roller 8222. The driving roller 8233 and the second driven roller 8234 can be arranged on the same horizontal plane. The conveyor belt 8231 can be wound around the driving roller 8233 and the second driven roller 8234. The second driving motor 8232 is connected to the driving roller 8233 to drive the driving roller 8233 to rotate. The second driving motor 8232 can be connected to the driving roller 8233 through a combination of a synchronous pulley and a synchronous belt.

[0308] As Fig.68 shown in Fig.68 , when the second assembly 500 is between 500i - 500j, the gluing operation can be performed.
