Description

Technical Field

[0001] This invention relates to the field of tissue paper production equipment technology, specifically a flattening device for tissue paper production. Background Technology

[0002] Currently, the two most common paper product packaging forms in daily life are facial tissues and rolls of paper. Facial tissues are more convenient to use, eliminating the step of tearing paper and allowing for quick extraction, thus resulting in a larger demand. The production process of facial tissues requires the use of a folding machine to fold and cut the tissues. Once a certain quantity of tissues is reached, they are conveyed by a conveyor belt to the next process for packaging. However, because facial tissues rely on gravity when folded, and the paper itself is relatively light, the overall structure tends to be loose. Therefore, it is necessary to flatten the tissues before packaging.

[0003] A paper towel flattening device for paper towel production is proposed in invention patent CN221214900U. It uses a shaping roller and slide bar to continuously flatten the folded paper towels during the conveying process, reducing the loosening caused by the rebound between the paper. However, the baffle in this device is fixed to the frame of the conveyor and cannot be adjusted in real time according to the specifications of the paper towels, resulting in poor applicability of the device. At the same time, when the machine jams or other malfunctions occur, the paper can easily get stuck in the flattening area on the conveyor belt. It is necessary to disassemble the flattening device in the flattening area to remove the paper towels, which is cumbersome and affects the continuity of production. Moreover, after disassembly, the position of each component needs to be recalibrated, which can easily lead to the deviation of the subsequent flattening accuracy and further reduce the yield of finished products. The device does not have a component to correct the side deviation of the paper towels, which can easily cause the paper towels to tilt to both sides, resulting in lateral misalignment of the upper and lower layers of paper towels during flattening, affecting the flattening effect.

The limiting shaft 404 is inserted into the limiting groove 405. A first guiding shaft 408 is fixedly connected to the inside of the first guiding plate 301. The slide bar 403 is slidably connected to the first guiding shaft 408. A first spring 409 is sleeved outside the first guiding shaft 408. The two ends of the first spring 409 are respectively fixedly connected with the slide bar 403 and the first guiding plate 301. Two inserting bars 406 are fixedly connected to the slide bar 403. One inserting slot 407 is provided on each side of the top end of the rotating plate 402. The inserting bar 406 is inserted into the inserting slot 407. A handle 410 is fixedly connected to the top end of the slide bar 403. A bolt 411 with a "dry" - shaped cross-section is slidably connected to the slide bar 403. Two inserting holes 412 are provided on the first guiding plate 301. The bolt 411 and the inserting holes 412 are used in cooperation;

The third guide posts 809 are slidably connected to the guide blocks 810. When the equipment jams and the paper towel gets stuck in the flattening area, first stop the equipment, then operate the removal structure 4. Pull the handle 410 to drive the slide bar 403 along the first guide shaft 4. 08 Slides, compressing the first spring 409, causing the limiting shaft 404 to disengage from the limiting groove 405 of the rotating shaft 401 and the insert 406 to disengage from the slot 407 of the rotating plate 402. Then, the pin 411 is inserted into the insertion hole 412 to fix the position of the slide bar 403. At this time, the rotating plate 402 can rotate around the rotating shaft 401, opening the side channel of the flattening area. Subsequently, the third handwheel 808 is rotated, which drives the worm gear 807 to rotate. The worm gear 807 drives the worm wheel 806 and the fourth screw 805 to rotate. The fourth screw 805 drives the lifting rod 803 and the lifting plate 804 to descend, conveying... The upper conveyor belt of machine 1 is elastic. After the lifting plate 804 descends, it will sink slightly, causing the conveyor belt to disengage from the pressure plate 204 and no longer press the paper towel. At this time, the paper towel can be quickly removed through the channel opened by the rotating plate 402. After removal, the pin 411 is pulled out, the first spring 409 resets and drives the slide bar 403 back to its original position, the limit shaft 404 and the insert bar 406 re-engage and fix the rotating plate 402, and the third handwheel 808 is rotated in the opposite direction to reset the lifting plate 804. The equipment can quickly resume production without disassembling the flattening parts, avoiding positional displacement that may affect the subsequent flattening accuracy.

Multiple first guide rods 304 are fixedly connected to both the first guide plate 301 and the second guide plate 302. The first guide rods 304 are slidably connected to the fixing blocks 303. The adjusting component includes a fixing plate 305. Two fixing plates 305 are fixedly connected to the frame of the conveyor 1. A first screw 306 is rotatably connected to the two fixing plates 305. Two drive bars 307 are symmetrically threaded onto the first screw 306. The thread directions at both ends of the first screw 306 are opposite. The two drive bars 307 are fixedly connected to the first guide plate 301 and the second guide plate 302 respectively. Two guide sleeves 308 are fixedly connected to the frame of the feeder 1.

The guide structure 3 is adjusted according to the width specification of the paper towel to be flattened. The second drive component 309 (preferably a motor) is started. The second drive component 309 drives the first screw 306 to rotate. The reverse threads at both ends of the first screw 306 drive the two drive bars 307 to move synchronously towards or away from each other. The drive bar 307 drives the first guide plate 301 and the second guide plate 302 to slide along the first guide rod 304 until the distance between the two guide plates is adapted to the width of the paper towel. The inclined end of the second guide plate 302 can provide preliminary guidance for the paper towel to avoid deviation during paper towel delivery.

[0043] Specifically, such as Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 9 , Figure 10 , Figure 14 and Figure 15As shown, the flattening structure 2 includes a gantry frame 201 and a first driving component 202.

Multiple exhaust channels 209 are linearly arrayed on the pad 205. Several capillary holes 210 are arrayed at the bottom of the pad 205. The capillary holes 210 are connected to the exhaust channels 209. After the paper towel enters the flattening area, the first driving component 202 (preferably a hydraulic cylinder) drives the mounting plate 203 and the pressure plate 204 to move downward. The pad 205 flattens the paper towel for the first time. During the flattening process, the air inside the paper towel flows into the exhaust channel 209 through the capillary holes 210 and is discharged to avoid air bubbles causing the flattening to be loose. Then, it enters the underside of the re-pressing component 208 to perform a second re-pressing on the paper towel to further eliminate the paper towel's rebound and improve the flattening effect.

[0044] Specifically, such as Figure 6 and Figure 9As shown, the mounting structure 5 includes a mounting groove 501 and a mounting rail 502. The mounting plate 203 has a T-shaped mounting groove 501.

When it is necessary to replace the pressure plate 204 or the pad 205, press the pressing strip 503 of the mounting structure 5 to compress the second spring 507, so that the locking block 504 is disengaged from the slot 505. Push the pressure plate 204 to drive the mounting rail 502 to slide along the mounting groove 501 for disassembly. During installation, slide the mounting rail 502 into the mounting groove 501, release the pressing strip 503, and the second spring 507 will reset so that the locking block 504 is locked into the slot 505. The third spring 509 can quickly push out the disassembled mounting rail 502 and pressure plate 204, avoiding the inconvenience of pulling out in a narrow space, improving the convenience of installation, and quickly completing the disassembly and replacement of the pressure plate 204.

A second handwheel 710 is fixedly connected to the end of the third screw 709. Rotating the second handwheel 710 drives the third screw 709 to rotate. The third screw 709 drives the support plate 704 to move along the slide rail 702 through the threaded seat 708, adjusting the position of the correction structure 7 to align it with the side of the paper towel. After completing the initial parameter debugging, the conveyor 1 and the flattening structure 2 are started. The folded paper towel is conveyed by the conveyor 1 and first passes through the correction structure 7. The third driving component 705 (preferably a hydraulic cylinder) drives the correction plate 706 to extend and retract, correcting the offset side of the paper towel in real time to ensure that the paper towel is conveyed in the center.

[0047] In use, the present invention first adjusts the guide structure 3 according to the width of the tissue paper to be flattened, and then starts the second drive component 309. The second drive component 309 drives the first screw 306 to rotate. The reverse threads at both ends of the first screw 306 drive the two drive bars 307 to move synchronously towards or away from each other. The drive bars 307 drive the first guide plate 301 and the second guide plate 302 to slide along the first guide rod 304 until the distance between the two guide plates matches the width of the tissue paper. The inclined end of the second guide plate 302 can provide preliminary guidance for the tissue paper to prevent it from deviating during the tissue paper conveying process. At the same time, the second handwheel 710 is rotated, which drives the third screw 709 to rotate. The third screw 709 drives the support plate 704 to move along the slide rail 702 through the threaded seat 708, adjusting the position of the correction structure 7 to align it with the side of the tissue paper, thus completing the initial parameter adjustment.

[0048] Then, the conveyor 1 and the flattening structure 2 are started. The folded paper towel is conveyed by the conveyor 1 and first passes through the correction structure 7. The third driving component 705 (preferably a hydraulic cylinder) drives the correction plate 706 to extend and retract, and corrects the offset side of the paper towel in real time to ensure that the paper towel is conveyed in the center. After the paper towel enters the flattening area, the first driving component 202 (preferably a hydraulic cylinder) drives the mounting plate 203 and the pressure plate 204 to move downward. The pad plate 205 flattens the paper towel for the first time. During the flattening process, the air inside the paper towel is discharged through the capillary pores 210 into the exhaust channel 209 to avoid air bubbles causing the flattening to be loose. Then, it enters the underside of the re-pressing component 208 to perform a second re-pressing of the paper towel to further eliminate the paper towel rebound and improve the flattening effect.

[0049] When the equipment malfunctions and the tissue gets stuck in the flattening area, first stop the equipment. Then, operate the removal structure 4. Pull the handle 410 to move the slide bar 403 along the first guide shaft 408, compressing the first spring 409. This causes the limiting shaft 404 to disengage from the limiting groove 405 of the rotating shaft 401 and the insert bar 406 to disengage from the slot 407 of the rotating plate 402. Then, insert the pin 411 into the insertion hole 412 to fix the position of the slide bar 403. At this time, the rotating plate 402 can rotate around the rotating shaft 401, opening the side channel of the flattening area. Then, rotate the third handwheel 808, which drives the worm gear 807 to rotate. The worm gear 807 drives the worm wheel 806 and the fourth screw 805 to rotate. The fourth screw 805 drives the lifting rod 803 and the lifting plate 804 to descend. The upper conveyor belt of the conveyor 1 is elastic, and under the lifting plate 804... After lowering, it will sink slightly, causing the conveyor belt to disengage from the pressure plate 204 and no longer press the paper towel. At this time, the paper towel can be quickly removed through the channel opened by the rotating plate 402. After removal, the pin 411 is pulled out, the first spring 409 resets and drives the slide bar 403 back to its original position, the limit shaft 404 and the insert bar 406 re-engage and fix the rotating plate 402, and the third handwheel 808 is rotated in the opposite direction to reset the lifting plate 804. The equipment can quickly resume production without disassembling the flattening component, avoiding positional displacement that may affect the subsequent flattening accuracy. When the paper towel gets stuck in the re-pressing area, the first handwheel 603 can be rotated, which will drive the second screw 602 to rotate, driving the slide bar 601 and the re-pressing component 208 to rise, thereby removing the paper towel pressed below. The setting of the second guide column 604 improves the stability of the re-pressing component 208 moving up and down.

[0050] Finally, when it is necessary to replace the pressure plate 204 or the pad 205, press the pressing strip 503 of the mounting structure 5 to compress the second spring 507, causing the locking block 504 to disengage from the slot 505. Push the pressure plate 204 to drive the mounting rail 502 to slide along the mounting groove 501 for disassembly. During installation, slide the mounting rail 502 into the mounting groove 501, release the pressing strip 503, and the second spring 507 will reset so that the locking block 504 is locked into the slot 505. The third spring 509 can quickly push out the disassembled mounting rail 502 and the pressure plate 204, avoiding the inconvenience of pulling out in a narrow space, improving the ease of installation, and quickly completing the disassembly and replacement of the pressure plate 204.
