Description

Technical Field

[0001] The invention relates to the technical field of plastic bag production, in particular to a forming and finishing device for the production of mildew-proof bags. Background Art

[0002] Anti-mildew bags are packaging materials that take certain protective measures to prevent the packaging and contents from mildewing. Anti-mildew bags mainly achieve moisture-proof and mildew-proof effects through their special materials and production processes. They can not only effectively isolate moisture from the external environment, but also inhibit the growth of mold, thereby protecting the items in the package from mildew. Among them, polyethylene, polypropylene and polyvinyl chloride (PVC) are plastic materials with good sealing and moisture resistance, and are commonly used materials for making anti-mildew bags; Anti-mildew bags come in a variety of shapes to meet the packaging needs and storage environments of different products. Hanging bags are designed with hanging holes or hooks on the top or side, which makes it easy to hang the anti-mildew bags on shelves, wardrobes or other places. This design makes the storage and retrieval of items more convenient, while also saving floor space; During the inspection, the "cutting device for paper and plastic bag production" in the prior art has a publication number of "CN218257097U". This device clamps the paper and plastic bags by the upper and lower pressure plates to avoid uneven cutting due to loose paper and plastic bags. However, during the transportation process, the anti-mildew bags may be stacked and offset due to material friction and other reasons, resulting in uneven processing and molding positions of the batch-trimmed packaging bags during processing. The poor trimming effect affects the product qualification rate. Summary of the invention

[0005] In one embodiment, the conveying and adjusting assembly includes a guide frame fixedly connected to the bottom wall of the forming and trimming chamber, the guide frame is located below the cutting seat, one end of the guide frame is rotatably connected to a threaded shaft, the other end of the threaded shaft penetrates the outside of the processing frame and is fixedly connected to the output shaft of the second servo motor, the surface of the threaded shaft is threadedly connected to the threaded frame, the upper end of the threaded frame is fixedly connected to a supporting frame, and both sides of the supporting frame are hinged with hinged side frames. When the device is in use, when the two preliminary positioning assemblies place the upper mildew-proof bag on the supporting frame, the hinged side frames on both sides can place the mildew-proof bag in a relatively centered position of the supporting frame to ensure the accuracy of subsequent cutting, and then the second servo motor can be driven to drive the threaded shaft to rotate, so that the threaded frame drives the supporting frame to follow and move synchronously, so that the supporting frame moves to the top of the guide frame, and at this time, the mildew-proof bag above the supporting frame can be trimmed by driving the cutting seat.

[0006] In one embodiment, the pneumatic centering assembly includes a mounting plate fixedly connected to the processing frame away from the surface of the forming and trimming chamber, and the other side of the mounting plate is fixedly connected to two circular cavities, the inner wall of the circular cavity is slidably connected to a piston, the inner wall of the piston is fixedly connected to a connecting round rod, the end of the connecting round rod penetrates the interior of the processing frame and is fixedly connected to the surface of the conveying adjustment assembly, and one side of the piston is fixedly connected to a spring, and the spring is fixedly connected to the inner wall of the circular cavity. The side of the piston near the air guide pipe in the circular cavity is a sealing section, and when the piston moves, the air pressure inside the sealing section gradually increases, and the movement of the connecting round rod is reset by the spring.

[0007] In one embodiment, the preliminary positioning assembly includes two positioning vertical frames fixedly connected to the inner bottom wall of the processing frame, the upper end of the positioning vertical frames is fixedly connected to two fixed tubes, a rotating shaft is rotatably connected between the two fixed tubes, one end of the rotating shaft passes through the outside of the processing frame and is fixedly connected to the output shaft of the first servo motor, the rotating shaft is fixedly connected to a plurality of connecting rods, and the surface of the connecting rod away from the rotating shaft is fixedly connected to two supporting plates. The two first servo motors rotate in opposite directions, the two first servo motors rotate at the same speed, and the connecting rods on the surface of the rotating shaft form an angle of 120 degrees with the adjacent connecting rods. The mildew-proof bag can be placed above the supporting plate between the two rotating shafts, and can be offset by an angle of plus or minus five to plus or minus ten degrees according to the placement state of the mildew-proof bag, so as to reduce the adsorption and adhesion of the edges of the stacked mildew-proof bags, so that the mildew-proof bags are stacked together to form an approximately fluffy state. At this time, the mildew-proof bag placed above the supporting plate is supported by the two supporting plates.

[0008] In one embodiment, a slideway is provided on the surface of the support plate, a sliding block is slidably connected to the inner wall of the slideway, a plurality of counterweight positioning blocks are provided between the two rotating shafts, and the counterweight positioning blocks are fixedly connected to the upper ends of the adjacent sliding blocks. When the support plate between the two rotating shafts continues to rotate, the sliding block located inside the slideway slides toward the end of the support plate away from the connecting rod under the action of gravity, and at this time, the counterweight positioning block is driven to contact the edge of the anti-mildew bag, and the relatively fluffy stacked anti-mildew bags move to the distance between the two rotating shafts under the action of the counterweight positioning block resisting and offsetting the edge of the anti-mildew bag, so as to help the stacked anti-mildew bags be neatly placed.

[0009] In one embodiment, an airbag is fixedly connected to the upper inclined surface of the articulated side frame, a soft rubber strip is fixedly connected to the surface of the airbag, the lower end of the soft rubber strip is fixedly connected to the surface of the supporting bottom frame, and a resisting protrusion is fixedly connected to the lower inclined surface of the articulated side frame. The airbag inside the articulated side frame assists in guiding the mildew-proof bag so that the mildew-proof bag is located in the middle of the supporting bottom frame, and at the same time, the multiple soft rubber strips are at an approximately vertical angle to the edges of the horizontally stacked mildew-proof bags, so that under the action of the soft rubber strips, air can easily enter between the stacked mildew-proof bags, reducing the airtight adsorption effect between the stacked mildew-proof bags, and assisting the mildew-proof bag alignment and sorting operation.

[0010] In one embodiment, two sliding channels are embedded and installed at the lower end of the supporting frame, and the inner wall of the sliding channel is slidably connected to a sliding seat, and the sliding seat is slidably connected to the inner bottom wall of the processing frame, one side of the sliding seat contacts the surface of the threaded frame, and the other side of the sliding seat is fixedly connected to a magnetic block. When the threaded shaft rotates, the threaded frame threadedly connected thereto is driven to perform a linear translational motion, and at the same time, the opposite sides of the two sliding seats are contacted by the threaded frame to move synchronously toward the direction of the guide frame, the middle of the adjacent side surface of the threaded frame is located between the two sliding seats, and the side surface of the threaded frame close to the end contacts the surface of the sliding seat.

[0011] In one of the embodiments, both sides of the lead-out frame are provided with a resistance frame fixedly connected to the bottom wall of the forming and trimming bin, the upper end of the resistance frame is wavy, and the end of the lead-out frame close to the sliding seat is fixedly connected to two electromagnets, and the electromagnets match the adjacent magnetic blocks. When the threaded frame drives the supporting frame to approach the lead-out frame, the threaded frame drives the two sliding seats to follow and move toward the lead-out frame, at which time the magnetic blocks are synchronously approached to the electromagnets, and then when the anti-mildew bag on the supporting frame is completely located above the lead-out frame, the magnetic block fits with the electromagnet, and the electromagnet is turned on at this time, so that the electromagnet and the adjacent magnetic blocks are tightly adsorbed together, and when the supporting frame is reset, the supporting frame moves while the sliding seat keeps its position relative to the lead-out frame unchanged, so that the cut anti-mildew bag is resisted by the sliding seat when the supporting frame is reset and the sliding seat does not move, and the trimmed anti-mildew bag falls off Above the lead-out rack, the cut waste is discharged to the outside through the square holes of the lead-out rack and the supporting base. When the supporting base is reset, the electromagnet is stopped so that the magnetic suction block is reset through the pneumatic centering component on the surface of the sliding seat. When it runs again, the sliding path can push the anti-mildew bag above the lead-out rack out of the forming and trimming bin. When the articulated side frame moves with the supporting base, the interference protrusion contacts the wavy edge of the interference frame on the same side. At this time, the upper ends of the articulated side frames on both sides are gathered toward the middle of the supporting base, and the anti-mildew bag above the supporting base is assisted in the centering alignment operation.

[0012] In one embodiment, a plurality of supporting rods are provided on both sides of the supporting plate, and the supporting rods on one side are installed on the surface of the adjacent connecting rods, and the adjacent supporting rods are staggered. When the supporting rods on both sides run between the two rotating shafts and are in a horizontal state, a stable placement surface is formed, and the supporting rods on both sides are staggered. When the supporting rods rotate with the connecting rods, they are combined into a shape between the two rotating shafts, and the mildew-proof bag is located in the placement area above the adjacent supporting rods.

[0013] In one embodiment, an air outlet is provided at the end of the circular cavity away from the second servo motor, and a plurality of evenly distributed arc-shaped side grooves are provided on the inner wall of the circular cavity. An air duct is connected to the lower end of the surface of the circular cavity away from the air outlet, and the other end of the air duct penetrates into the interior of the processing frame and is connected to the airbag. When the air pressure in the sealed section inside the circular cavity increases, gas is injected into the airbag through the air duct so that the airbag can expand. Since the arc-shaped side grooves provided on the inner wall of the circular cavity are evenly distributed, when the piston moves on the inner wall of the circular cavity, a periodic high pressure is formed in the sealed section. When the piston moves to the position of the arc-shaped side grooves, the air pressure in the sealed section is balanced with the external air pressure through the arc-shaped side grooves and the air outlet, and the moving speed of the connecting round rod is relatively balanced through the opened air outlet.

[0014] The above-mentioned production forming and trimming equipment of the mildew-proof bag can place the mildew-proof bag on the top of the supporting bottom frame for transportation through the provided conveying adjustment component. Meanwhile, the abutment protrusions on the side of the hinged side frame can cooperate with the abutment frame to gather toward the middle during the transportation process, and assist in trimming the edge of the mildew-proof bag, so that the neat mildew-proof bag can be cut in cooperation with the cutting seat during the cutting process. When cutting, the cutting waste and the trimmed mildew-proof bag can be separately exported to ensure that the subsequent cutting is not affected, so that the mildew-proof bag can be trimmed and cut continuously to maintain a neat and good trimming effect. The device can perform preliminary sorting operations on the placed mildew-proof bags through the preliminary positioning component, and its conveying method is adjusted from the traditional horizontal dragging after clamping to vertical placement, which reduces the deviation of the stacked mildew-proof bags caused by clamping and dragging. At the same time, in the process of vertical transfer, it can also assist in the middle alignment of the stacked mildew-proof bags, which is convenient for subsequent molding and trimming operations; The device cooperates with the pneumatic centering component to drive the conveying adjustment component to drive the stacked mildew-proof bags to move, while driving the connecting round rod to move synchronously, so that the piston will move in the circular cavity. By opening multiple arc-shaped side grooves, the sealing section can form periodic high pressure, and then the gas will be injected into the interior of the airbag through the sliding seat to assist in the alignment of the stacked mildew-proof bags above the supporting frame, thereby ensuring the qualified rate of trimming and forming.

[0023] Combine the following Figure 1-Figure 9The molding and trimming equipment for producing mildew-proof bags of the present invention comprises: a processing frame 100, a molding and trimming chamber 200 is installed on one side of the processing frame 100, and a cutting seat 210 is fixedly connected to the inner top wall of the molding and trimming chamber 200; a trimming mechanism 300, the trimming mechanism 300 is installed inside the processing frame 100, and the surface of the trimming mechanism 300 penetrates to the outside of the processing frame 100 and extends to the bottom of the cutting seat 210; wherein the trimming mechanism 300 comprises two preliminary positioning components 310 arranged inside the processing frame 100, the upper end of the preliminary positioning component 310 penetrates to the top of the processing frame 100, and the preliminary positioning component 310 is provided at the bottom of the processing frame 100. One end of the positioning assembly 310 penetrates to the outside of the processing frame 100, and two pneumatic centering assemblies 330 are installed on the side of the processing frame 100 away from the forming and trimming chamber 200. The pneumatic centering assembly 330 is connected to the surface of the preliminary positioning assembly 310. A conveying adjustment assembly 320 is arranged below the preliminary positioning assembly 310. One end of the conveying adjustment assembly 320 away from the first servo motor 340 penetrates to the bottom of the cutting seat 210. A second servo motor 350 installed on the side of the processing frame 100 is arranged below the first servo motor 340, and the second servo motor 350 is connected to the surface of the conveying adjustment assembly 320. like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the conveying adjustment assembly 320 includes a guide frame 3213 fixedly connected to the inner bottom wall of the forming and trimming chamber 200, the guide frame 3213 is located below the cutting seat 210, one end of the guide frame 3213 is rotatably connected to a threaded shaft 321, the other end of the threaded shaft 321 penetrates the outside of the processing frame 100 and is fixedly connected to the output shaft of the second servo motor 350, the surface of the threaded shaft 321 is threadedly connected to a threaded frame 322, the upper end of the threaded frame 322 is fixedly connected to a supporting frame 323, and both sides of the supporting frame 323 are hingedly connected to an articulated side frame 326. An airbag 329 is fixedly connected to the upper inclined surface of the articulated side frame 326, a soft rubber strip 3210 is fixedly connected to the surface of the airbag 329, the lower end of the soft rubber strip 3210 is fixedly connected to the surface of the supporting frame 323, and a resisting protrusion 328 is fixedly connected to the lower end inclined surface of the articulated side frame 326. Two sliding channels 324 are embedded and installed at the lower end of the supporting base frame 323. The inner wall of the sliding channel 324 is slidably connected with a sliding seat 325. The sliding seat 325 is slidably connected to the inner bottom wall of the processing frame 100. One side of the sliding seat 325 contacts the surface of the threaded frame 322, and the other side of the sliding seat 325 is fixedly connected to a magnetic suction block 3211. Both sides of the lead-out frame 3213 are provided with a contact frame 327 fixedly connected to the inner bottom wall of the forming and trimming chamber 200. The upper end of the contact frame 327 is wavy. The end of the lead-out frame 3213 close to the sliding seat 325 is fixedly connected with two electromagnets 3212, and the electromagnets 3212 match the adjacent magnetic suction blocks 3211. When the device is in use, the two preliminary positioning components 310 place the upper mildew-proof bag on the supporting frame 323, and the hinged side frames 326 on both sides can place the mildew-proof bag in a relatively centered position on the supporting frame 323 to ensure the accuracy of subsequent cutting. After that, the second servo motor 350 can be driven to drive the threaded shaft 321 to rotate, so that the threaded frame 322 drives the supporting frame 323 to follow and translate synchronously, so that the supporting frame 323 moves to the top of the export frame 3213. At this time, the cutting seat 210 can be driven to trim the mildew-proof bag above the supporting frame 323. The airbag 329 on the inner side of the hinged side frame 326 assists in guiding the mildew-proof bag so that the mildew-proof bag is located in the middle of the supporting bottom frame 323. At the same time, the multiple soft rubber strips 3210 are at an approximately vertical angle to the edges of the horizontally stacked mildew-proof bags, so that under the action of the soft rubber strips 3210, air can easily enter between the stacked mildew-proof bags, reducing the airtight adsorption effect between the stacked mildew-proof bags and assisting the alignment and sorting of the mildew-proof bags. When the threaded shaft 321 rotates, it drives the threaded frame 322 threadedly connected thereto to perform a linear translational motion. At the same time, the opposite sides of the two sliding seats 325 are resisted by the threaded frame 322 and move synchronously toward the direction of the guide frame 3213. The middle of the adjacent side of the threaded frame 322 is located between the two sliding seats 325, and the side of the threaded frame 322 close to the end contacts the surface of the sliding seat 325. When the threaded frame 322 drives the supporting frame 323 to approach the lead-out frame 3213, the threaded frame 322 drives the two sliding seats 325 to move toward the lead-out frame 3213, and at this time, the magnetic block 3211 is synchronously close to the electromagnet 3212, and then when the mildew-proof bag on the supporting frame 323 is completely located above the lead-out frame 3213, the magnetic block 3211 fits with the electromagnet 3212, and the electromagnet 3212 is turned on at this time, so that the electromagnet 3212 and the adjacent magnetic block 3211 are tightly adsorbed together, and when the supporting frame 323 is reset, the supporting frame 323 moves while the sliding seat 325 keeps its position relative to the lead-out frame 3213 unchanged, so that the cut mildew-proof bag is resisted by the sliding seat 325 when the supporting frame 323 is reset and the sliding seat 325 is not moved. The trimmed mildew-proof bag falls on the top of the lead-out rack 3213, and the cut waste is discharged to the outside through the square holes of the lead-out rack 3213 and the supporting bottom rack 323. When the supporting bottom rack 323 is reset, the electromagnet 3212 is stopped so that the magnetic suction block 3211 is reset through the pneumatic centering component 330 on the surface of the sliding seat 325. When it is running again, the sliding channel 324 can push the mildew-proof bag on the top of the lead-out rack 3213 out of the forming and trimming bin 200. When the articulated side rack 326 moves with the supporting bottom rack 323, the abutting protrusion 328 contacts the wavy edge of the abutting rack 327 on the same side, so that the upper ends of the articulated side racks 326 on both sides are gathered toward the middle of the supporting bottom rack 323, and the mildew-proof bag on the supporting bottom rack 323 is assisted in the centering alignment operation. like Figure 1 , Figure 2 , Figure 5 , Figure 8 , Fig. 9 As shown, the pneumatic centering assembly 330 includes a mounting plate 331 fixedly connected to the surface of the processing frame 100 away from the forming and trimming chamber 200, and two circular cavities 332 are fixedly connected to the other side of the mounting plate 331. The inner wall of the circular cavity 332 is slidably connected with a piston 334, and the inner wall of the piston 334 is fixedly connected with a connecting round rod 333. The end of the connecting round rod 333 penetrates into the interior of the processing frame 100 and is fixedly connected to the surface of the conveying adjustment assembly 320. A spring 337 is fixedly connected to one side of the piston 334, and the spring 337 is fixedly connected to the inner wall of the circular cavity 332. An air outlet 336 is provided at the end of the circular cavity 332 away from the second servo motor 350, and a plurality of evenly distributed arc-shaped side grooves 338 are provided on the inner wall of the circular cavity 332. The lower end of the surface of the circular cavity 332 away from the air outlet 336 is connected with an air guide tube 335, and the other end of the air guide tube 335 penetrates into the interior of the processing frame 100 and is connected to the air bag 329. The side of the piston 334 near the air guide tube 335 in the circular cavity 332 is a sealing section. When the piston 334 moves, the air pressure inside the sealing section gradually increases, and the movement of the connecting rod 333 is reset by the spring 337. When the air pressure in the sealing section inside the circular cavity 332 increases, gas is injected into the airbag 329 through the air guide tube 335, so that the airbag 329 can expand. Since the arc-shaped side grooves 338 opened on the inner wall of the circular cavity 332 are evenly distributed, when the piston 334 moves on the inner wall of the circular cavity 332, periodic high pressure is formed in the sealing section. When the piston 334 moves to the position of the arc-shaped side grooves 338, the air pressure in the sealing section is balanced with the external air pressure through the arc-shaped side grooves 338 and the air outlet 336, and the movement speed of the connecting rod 333 is relatively balanced through the opened air outlet 336. like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the preliminary positioning assembly 310 includes two positioning vertical frames 311 fixedly connected to the inner bottom wall of the processing frame 100, two fixed tubes 312 are fixedly connected to the upper ends of the positioning vertical frames 311, a rotating shaft 313 is rotatably connected between the two fixed tubes 312, one end of the rotating shaft 313 penetrates the outside of the processing frame 100 and is fixedly connected to the output shaft of the first servo motor 340, a plurality of connecting rods 314 are fixedly connected to the rotating shaft 313, and two supporting plates 315 are fixedly connected to the surface of the connecting rod 314 away from the rotating shaft 313. A slideway 317 is provided on the surface of the supporting plate 315, and a sliding block 318 is slidably connected to the inner wall of the slideway 317, and a plurality of counterweight positioning blocks 319 are arranged between the two rotating shafts 313, and the counterweight positioning blocks 319 are fixedly connected to the upper ends of adjacent sliding blocks 318. A plurality of supporting rods 316 are provided on both sides of the supporting plate 315. The supporting rods 316 on one side are installed on the surface of the adjacent connecting rod 314, and the adjacent supporting rods 316 are staggered. The two first servo motors 340 rotate in opposite directions, and the rotation speeds of the two first servo motors 340 are consistent. The connecting rods 314 on the surface of the rotating shaft 313 form an angle of 120 degrees with the adjacent connecting rods 314. The mildew-proof bag can be placed on the supporting plate 315 between the two rotating shafts 313. The angle can be shifted by plus or minus five degrees to plus or minus ten degrees according to the placement state of the mildew-proof bag, so as to reduce the adsorption and adhesion of the edges of the stacked mildew-proof bags, so that the mildew-proof bags are stacked together to form a nearly fluffy state. At this time, the mildew-proof bag placed on the supporting plate 315 is supported by the two supporting plates 315. When the supporting plate 315 located between the two rotating shafts 313 continues to rotate, the sliding block 318 located inside the slide 317 slides toward the end of the supporting plate 315 away from the connecting rod 314 under the action of gravity, and at this time drives the counterweight positioning block 319 to contact the edge of the mildew-proof bag. The relatively fluffy stacked mildew-proof bags move to the distance between the two rotating shafts 313 under the action of the counterweight positioning block 319 resisting the edge of the mildew-proof bag, so as to assist the stacked mildew-proof bags to be neatly placed. When the supporting rods 316 on both sides run to between the two rotating shafts 313 and are in a horizontal state, a stable placement surface is formed, and the supporting rods 316 on both sides are staggered. When the supporting rods 316 follow the connecting rod 314 to rotate, they are combined into an X shape between the two rotating shafts 313. At this time, the mildew-proof bag is located in the placement area above the adjacent supporting rods 316.

[0024] Working principle: The two first servo motors 340 are driven to drive the rotating shaft 313 to rotate accordingly, and the mildew-proof bag is placed above the supporting plate 315 and the supporting rod 316 between the two rotating shafts 313. When the supporting rods 316 on both sides run between the two rotating shafts 313 and are in a horizontal state, a stable placement surface is formed, and the supporting plate 315 between the rotating shafts 313 continues to rotate accordingly, and the sliding block 318 located in the slideway 317 slides toward the end of the supporting plate 315 away from the connecting rod 314, driving the counterweight positioning block 319 to collide with the edge of the mildew-proof bag. Finally, the supporting rods 316 on both sides are separated to place the mildew-proof bag above the supporting base frame 323, and the mildew-proof bag is located in the middle of the supporting base frame 323. The second servo motor 350 is driven to drive the threaded shaft 321 to rotate so that the threaded frame 322 drives the supporting base frame 323 approaches the lead-out frame 3213, and the two sliding seats 325 are driven to move toward the lead-out frame 3213 by the threaded frame 322, and the magnetic block 3211 approaches the electromagnet 3212 synchronously, and when the mildew-proof bag on the supporting frame 323 is completely located above the lead-out frame 3213, the magnetic block 3211 fits with the electromagnet 3212, and the electromagnet 3212 is turned on to attract the magnetic block 3211, and the supporting frame 323 moves the sliding seat 325 to keep the position unchanged relative to the lead-out frame 3213, and the cut mildew-proof bag is resisted by the sliding seat 325 when the supporting frame 323 is reset and the sliding seat 325 is not moved, and the trimmed mildew-proof bag falls on the top of the lead-out frame 3213, and the cut waste is discharged to the outside through the square holes of the lead-out frame 3213 and the supporting frame 323; When the holding base frame 323 is reset, the stop electromagnet 3212 and the magnetic block 3211 are reset through the pneumatic centering component 330 on the surface of the sliding seat 325. When it is running again, the sliding channel 324 pushes the mildew-proof bag above the guide frame 3213 out of the forming and trimming chamber 200. When the hinged side frame 326 moves with the holding base frame 323, the abutment protrusion 328 contacts the wavy edge of the abutment frame 327 on the same side. The upper ends of the hinged side frames 326 on both sides are gathered toward the middle of the holding base frame 323 to assist the centering and alignment operation of the mildew-proof bag above the holding base frame 323. When the air pressure in the sealed section of the circular cavity 332 increases, gas is injected into the air chamber through the air guide pipe 335. In the bag 329, the air bag 329 expands, and when the piston 334 moves on the inner wall of the circular cavity 332, a periodic high pressure is formed in the sealing section. When the piston 334 moves to the position of the arc-shaped side groove 338, the air pressure in the sealing section is balanced with the external air pressure through the arc-shaped side groove 338 and the air outlet 336, and the moving speed of the connecting round rod 333 is relatively balanced through the opened air outlet 336, so that the air bag 329 can be expanded in stages during the movement of the pneumatic centering component 330. The soft rubber strip 3210 on the surface of the air bag 329 will form a staged resistance to the edge of the anti-mildew bag, which will assist the alignment operation before cutting and trimming of the anti-mildew bag and ensure the qualified rate of cutting and trimming of the anti-mildew bag.
