Description

Technical Field

[0001] The present invention relates to a heat-sealing splicing device, specifically a heat-sealing splicing device for preventing loosening and its application in the production of disposable diapers. Background Art

[0002] The heat-sealing splicing device heats the contact surfaces of two materials to a molten state by heating, and then applies a certain pressure to bond them together. At this time, the device needs to ensure a certain stability of the joint during the merging process to prevent the final bonding effect from being affected by loosening or deformation. The heat-sealing splicing device for preventing loosening is usually used in industrial fields, such as the processing of materials such as disposable diapers, non-woven fabrics, films, plastics, etc. Its main function is to prevent the joint from loosening or the structure from being unstable due to factors such as temperature, pressure, and mechanical force during the heat-sealing process.

[0003] When the current heat-sealing splicing device for preventing loosening is in use, especially when heat-sealing and processing materials such as non-woven fabrics, impurities may be left on the heat-sealing plate due to excessive temperature. Non-woven fabrics are usually made of materials such as polypropylene (PP) and polyester (PET). These materials may melt, adhere, or decompose at high temperatures. Especially if the heat-sealing temperature is inappropriate or the heat-sealing time is too long, melted impurities will remain on the heat-sealing plate. Then, during the next heat-sealing process, the heat-sealing effect will be affected, resulting in incomplete fusion of some parts of the heat-sealed materials, and loose problems will occur at the parts of the materials that are not heat-sealed. When cleaning the impurities on the heat-sealing plate of the heat-sealing splicing device, after the heat-sealing plate completely rises and resets, an external driving device is used to drive the cleaning mechanism for impurity cleaning to clean the impurities on the heat-sealing plate. During this cleaning process, it is necessary to wait for the heat-sealing plate to completely rise and reset to meet the movement stroke of the cleaning mechanism, and the cleaning mechanism can clean the impurities on the surface of the heat-sealing plate. As a result, the downtime of the heat-sealing machine is relatively long, and it needs to wait for the cleaning mechanism to complete the entire cleaning movement stroke before it can operate. This causes more heat loss of the heat-sealing plate and more consumption of the driving energy for generating the heat of the heat-sealing plate, affecting the heat-sealing efficiency and increasing the driving energy consumption of the heat-sealing machine.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] See also Figures 1 to 3 In the embodiment of the present invention, the anti-loose heat-sealing splicing device comprises a body 1, a lifting and mounting plate 3 fixed to one end of a hydraulic cylinder telescopic rod arranged on the body 1, and a heat-sealing plate 2 arranged on the lifting and mounting plate 3, and a linkage clearing structure is arranged on the body 1, and the linkage clearing structure is connected to the heat-sealing plate 2 and the lifting and mounting plate 3;

[0047] The linkage cleaning structure includes two mounting mechanisms symmetrically arranged on both sides of the machine body 1, a lifting mechanism connected to the mounting mechanism, a transmission mechanism connected to the mounting mechanism and the lifting mechanism, and a sliding cleaning mechanism connected to the transmission mechanism. The transmission mechanism is connected to the lifting mounting plate 3, and the scraper 31 in the sliding cleaning mechanism is in sliding contact with the pressing contact surface of the heat-sealing plate 2;

[0048] When the lifting mounting plate 3 and the heat-sealing plate 2 perform lifting heat-sealing operations, they drive the transmission mechanism to act. When the transmission mechanism acts, it drives the sliding cleaning mechanism to slide, so that the scraper 31 in the sliding cleaning mechanism slides and contacts the pressing contact surface of the heat-sealing plate 2. When the transmission mechanism acts, the lifting mechanism lifts and adjusts within the mounting mechanism to drive the sliding cleaning mechanism to lift and lower in linkage with the heat-sealing plate 2 and the lifting mounting plate 3.

[0049] In this embodiment, when heat-sealing the material by lifting the lifting mounting plate 3 and the heat-sealing plate 2, the lifting mounting plate 3 can drive the linkage movement of the transmission mechanism. When the transmission mechanism moves, the sliding cleaning mechanism can be slidably adjusted, so that the scraper 31 abuts against the heat-sealing contact surface of the heat-sealing plate 2 and scrapes, so that the residual molten impurities on the heat-sealing plate 2 are scraped, cleaned and collected. When the transmission mechanism operates, it can make the lifting mechanism slide up and down on the mounting mechanism, so that the transmission mechanism and the sliding cleaning mechanism can be linked up and down following the lifting of the heat-sealing plate 2 and the lifting mounting plate 3. Through the cooperative design, the operating speed of the lifting mechanism is slower than the lifting speed of the heat-sealing plate 2 and the lifting mounting plate 3, so that the transmission mechanism and the sliding cleaning mechanism are slower than the descending speed of the heat-sealing plate 2 and the lifting mounting plate 3. The design of the sliding cleaning mechanism enables the sliding cleaning mechanism to be forced to move downward under the downward pressure of the heat-sealing plate 2 and the lifting mounting plate 3 to meet the movement use. Through the design, it is possible to clean the impurities remaining on the heat-sealing contact surface of the heat-sealing plate 2, avoid the remaining molten impurities on the heat-sealing plate 2, and affect the subsequent heat-sealing processing of the material. If the heat-sealing temperature is too high, materials such as polypropylene or polyester will melt and adhere to the surface of the heat-sealing plate 2, which will cause residues or impurities of non-woven fabric to remain on the heat-sealing plate 2, affecting the heat-sealing effect in the next production process, avoiding incomplete heat-sealing caused by residual impurities, making the material loose, improving the heat-sealing effect. If the temperature is too high, it may also cause local overheating, coking or deformation on the surface of the non-woven fabric, thereby affecting the appearance and quality of the product. If a high temperature reacts with impurities in the air, it may produce carbon deposition or other pollutants on the heat-sealing plate 2, which will affect the heat-sealing quality and increase the cost of cleaning and maintenance. Regularly clean the heat-sealing plate 2 and the equipment to remove the remaining materials or pollutants to avoid affecting subsequent production. Therefore, this solution designs a structure that can perform self-cleaning along with the action during heat-sealing to clean the molten impurities on the heat-sealing plate 2, which can improve the heat-sealing effect and avoid the problem of looseness caused by incomplete heat-sealing.

[0050] Please refer to Figure 5 、 Figure 6 As a further solution of the present invention, the mounting mechanism includes an adjustment frame 4 fixedly mounted on the machine body 1 and two mounting rods 8 symmetrically and fixedly connected to one side of the adjustment frame 4;

[0051] A sliding groove 5 is formed in the adjustment frame 4. One end of the mounting rod 8 away from the adjustment frame 4 is rotatably connected to a second transmission wheel 10. A first hexagonal hole 11 is formed in the central portion of the second transmission wheel 10, and the first hexagonal hole 11 penetrates through the mounting rod 8.

[0052] In this embodiment, the adjustment frame 4 is installed on the body 1 to meet the requirements of installation and use. The two installation rods 8 symmetrically arranged on one side of the adjustment frame 4 are both rotatably connected to the second transmission wheel 10. The second transmission wheel 10 is connected to the transmission mechanism. When the transmission mechanism is running, it can drive the second transmission wheel 10 to rotate at one end of the installation rod 8 to meet the requirements of linkage use.

[0053] See also Figure 5 , Figure 6 As a further solution of the present invention, the adjusting frame 4 is symmetrically rotatably connected to two studs 6, the tops of the two studs 6 are fixedly connected to a first transmission wheel 7, the first transmission wheel 7 is transmission-connected to the second transmission wheel 10 through a belt 9, and the studs 6 are connected to the lifting mechanism;

[0054] The lifting mechanism includes a lifting plate 12, one side of the lifting plate 12 is slidably connected to the sliding groove 5, one side of the lifting plate 12 slidably connected to the sliding groove 5 is symmetrically provided with threaded holes, the threaded holes are threadedly connected to the stud 6, and the other side of the lifting plate 12 is symmetrically provided with round holes with a diameter larger than the first hexagonal hole 11;

[0055] The lifting plate 12 is symmetrically connected with a transmission mechanism.

[0056] In this embodiment, the stud 6 is threadedly connected to the lifting plate 12, and the first transmission wheel 7 at the top of the stud 6 is linked to the second transmission wheel 10 through the belt 9. When the second transmission wheel 10 is driven by the transmission mechanism to rotate, the second transmission wheel 10 will cause the stud 6 and the first transmission wheel 7 to rotate together, and the lifting plate 12, which is threadedly connected to the stud 6 and slidably connected to the sliding groove 5, will slide and rise and fall in the sliding groove 5, thereby achieving the effect of linked lifting. The lifting speed of the lifting plate 12 in the sliding groove 5 is slower than the lifting speed of the heat sealing plate 2 and the lifting installation plate 3. When the heat sealing plate 2 is attached to the material, the sliding removal mechanism slides to both sides of the heat sealing plate 2, which will not hinder its heat sealing work, thereby meeting the use requirements.

[0057] See also Figure 7 , Figure 8 As a further solution of the present invention, the transmission mechanism includes two columns 13 rotatably connected to the lifting plate 12, a first prism 14 fixedly connected to the top of the column 13, and a linkage component connected to the column 13, and the linkage component is installed on the lifting installation plate 3;

[0058] The top of the first prism 14 is fixedly connected to a limiting head 15, and the first prism 14 is slidably inserted into a circular hole provided on the lifting plate 12, and the first prism 14 is slidably inserted into the first hexagonal hole 11;

[0059] The column 13 is respectively provided with a spiral groove 16 and a vertical groove 17 , the spiral groove 16 and the vertical groove 17 are connected, and a second hexagonal hole 18 is provided at the center of the bottom of the column 13 .

[0060] In this embodiment, the linkage component is raised and lowered together with the lifting mounting plate 3. When the lifting mounting plate 3 is raised and lowered, the linkage component drives the column 13 to rotate. The first prism 14 on the top of the column 13 is slidably inserted into the first hexagonal hole 11. Even when the column 13 is lowered for adjustment, the column 13 can still transmit with the second transmission wheel 10. When the column 13 rotates, it drives the second transmission wheel 10 to rotate together, thereby satisfying the linkage use effect.

[0061] See also Figure 9 As a further solution of the present invention, the linkage assembly includes a driving plate 19 and two plug holes 20 symmetrically opened on the driving plate 19;

[0062] The driving plate 19 is fixedly connected to the lifting installation plate 3 at one side away from the plug hole 20, and a convex circle 21 is fixedly connected to the inner wall of the plug hole 20;

[0063] The insertion hole 20 is slidably sleeved on the column 13, the convex circle 21 is correspondingly slidably abutted against the spiral groove 16 and the vertical groove 17, and the column 13 is connected to a sliding clearing mechanism.

[0064] In this embodiment, the plug hole 20 provided on the driving plate 19 is slidably plugged with the column 13, and the convex circle 21 on the inner wall of the plug hole 20 slides and conflicts with the spiral groove 16 and the vertical groove 17 provided on the column 13. The driving plate 19 is installed on the lifting and mounting plate 3. When the lifting and mounting plate 3 descends, since the convex circle 21 on the inner wall of the plug hole 20 cannot rotate, the convex circle 21 will slide and conflict in the spiral groove 16, so that the column 13 rotates, thereby satisfying the lifting and lowering adjustment movement stroke of the driving plate 19. When the column 13 rotates, the column 13 will drive the second transmission wheel 10 to rotate together, and the second transmission wheel 10 will cause the stud 6 to rotate, so that the lifting plate 12 is lifted and lowered in the sliding groove 5. Since one end of the column 13 is rotatably connected to the lifting plate 12, when the lifting plate 12 is lifted and lowered, the column 13 will follow the lifting and lowering adjustment, which meets the movement stroke use effect of the heat-sealed plate 2 and the lifting and mounting plate 3, will not cause movement interference, and satisfies the linkage use.

[0065] See also Figure 10 , Figure 11 As a further solution of the present invention, the sliding clearing mechanism includes a second prism 24 slidably plugged with the column 13 and an abutment plate 22 fixedly connected to the second prism 24;

[0066] The second prism 24 is slidably inserted into a second hexagonal hole 18 formed at the bottom of the column 13. A limiting block 26 is fixedly connected to the top of the second prism 24. The bottom end of the limiting block 26 abuts against a spring 25. The spring 25 is sleeved on the second prism 24, and the outer end of the spring 25 abuts against the inner wall of the second hexagonal hole 18.

[0067] There are two contact discs 22. The two contact discs 22 are fixedly connected by a gear 23. The diameter sizes of the two contact discs 22 are larger than the diameter size of the gear 23. The gear 23 is connected to the rubbing component.

[0068] In this embodiment, since the lifting speed of the lifting plate 12 in the sliding groove 5 is slower than that of the heat-sealing plate 2 and the lifting mounting plate 3, when the heat-sealing plate 2 and the lifting mounting plate 3 descend, the heat-sealing plate 2 will abut against the rubbing component, forcing the rubbing component to descend accordingly. At this time, the second prism 24 will be inserted into the second hexagonal hole 18. When the distance between the limiting block 26 and the port of the second hexagonal hole 18 is reduced, the spring 25 will be compressed and contracted to maintain a resilient force. The insertion stroke of the second prism 24 in the second hexagonal hole 18 can compensate for the descending stroke of the lifting plate 12 in the sliding groove 5 that is slower than that of the heat-sealing plate 2 and the lifting mounting plate 3, ensuring that the descending operation of the heat-sealing plate 2 and the lifting mounting plate 3 will not be hindered. When the second prism 24 is slidably inserted into the second hexagonal hole 18, the rotational force of the column 13 can still drive the contact discs 22 and the gear 23 to rotate, meeting the rotational driving requirement of the rubbing component and ensuring the combined use effect.

[0069] Please refer to Figure 12 , as a further solution of the present invention, the rubbing component includes a telescopic frame 27 and tooth openings 28 provided on both sides of the telescopic frame 27;

[0070] The tooth openings 28 are meshed with the gear 23. The upper and lower sides of the telescopic frame 27 are slidably attached between the two contact discs 22. On the other side of the telescopic frame 27, mounting heads 29 are symmetrically and fixedly connected. The mounting heads 29 are connected to the collection component.

[0071] In this embodiment, the tooth openings 28 are meshed with the gear 23, and the telescopic frame 27 is slidably connected between the two contact discs 22. By fitting the upper and lower sides of the telescopic frame 27 between the two contact discs 22, the telescopic frame 27 can be kept horizontally moved and adjusted. Since a gear 23 meshed with the tooth opening 28 is provided on each side of the telescopic frame 27, when the two gears 23 rotate synchronously in opposite directions, the telescopic frame 27 can be moved and adjusted to meet the driving and adjusting use. By moving and adjusting the telescopic frame 27, the collection component can be made to abut and slide on the heat-sealing contact surface of the heat-sealing plate 2, achieving the use effect of removing the residues on the heat-sealing plate 2 and meeting the use requirements.

[0072] Please refer to Figure 12 , as a further solution of the present invention, the collecting assembly includes a collecting frame 30 with two ends respectively connected to two mounting heads 29, and a scraper 31 fixedly connected to the side of the collecting frame 30 away from the telescopic frame 27; the scraper 31 can be made of ceramic material (such as silicon nitride) or tungsten alloy material. The scraper 31 made of such materials has a high melting point and excellent anti-wear performance. When the scraper 31 scrapes and cleans the heat-sealing contact surface of the heat-sealing plate 2, the force exerted by the scraper 31 on the heat-sealing contact surface of the heat-sealing plate 2 and the sharpness of the cutting edge of the scraper 31 will not cause the heat-sealing contact surface of the heat-sealing plate 2 to be scratched, and only the function of scraping and cleaning impurities can be realized, avoiding the heat-sealing contact surface of the heat-sealing plate 2 from being scratched and ensuring the long-term use of the heat-sealing plate 2;

[0073] The scraper 31 is arranged in a right-angled triangle shape, and both sides of the right-angled side of the scraper 31 coincide with both sides of the right-angled side of the top of the collecting frame 30 away from the telescopic frame 27 respectively.

[0074] In this embodiment, collecting assemblies are arranged on both sides of the machine body 1, as well as the components connected to the collecting assemblies. When the heat-sealing plate 2 and the lifting mounting plate 3 rise to the original position after heat-sealing, the two scrapers 31 will fit together. The two scrapers 31 are at the middle line position of the heat-sealing plate 2. And because the lifting speed of the lifting plate 12 in the sliding groove 5 is slower than the lifting speed of the heat-sealing plate 2 and the lifting mounting plate 3, at this time, the two scrapers 31 are in a state of leaving a certain distance from the heat-sealing plate 2. When the heat-sealing plate 2 and the lifting mounting plate 3 are lowered, when the two scrapers 31 are about to separate, the heat-sealing contact surface of the heat-sealing plate 2 will abut against the two scrapers 31. At this time, the lifting mounting plate 3 will drive the driving plate 19 to descend, the driving plate 19 will drive the column 13 to rotate, and the gear 23 will drive the telescopic frame 27 to slide and adjust. At this time, under the sliding adjustment of the two telescopic frames 27, the distance between the two scrapers 31 gradually increases, so that the two scrapers 31 scrape synchronously to both sides at the middle line position of the heat-sealing plate 2. When the scraper 31 scrapes the heat-sealing plate 2, the molten impurities remaining on the heat-sealing plate 2 can fall into the collecting frame 30 for collection;

[0075] The descending speed of the heat-sealing plate 2 and the lifting mounting plate 3 is greater than the descending speed of the lifting plate 12 in the sliding groove 5, and the insertion stroke of the second prism 24 in the second hexagonal hole 18 can make up for the slower descending stroke of the scraping component and the collecting component than that of the heat-sealing plate 2 and the lifting mounting plate 3. Therefore, it does not affect the descending movement of the heat-sealing plate 2 and the lifting mounting plate 3. When the heat-sealing plate 2 is about to contact the material to be heat-sealed, at this time, the two scrapers 31 are at the two end edges of the heat-sealing plate 2. As the heat-sealing plate 2 and the lifting mounting plate 3 are pressed down, at this time, the convex circle 21 at the driving plate 19 will move to the position of the vertical groove 17. Since the vertical groove 17 is vertically opened, when the convex circle 21 moves to the position of the vertical groove 17, the column 13 will not rotate accordingly. Therefore, the lifting plate 12 will not be adjusted in the sliding groove 5, and the telescopic frame 27 will not move between the two abutting discs 22. At this time, the scraper 31 has moved to both ends of the heat-sealing plate 2, and it will not affect the heat-sealing operation of pressing down the heat-sealing plate 2 either, meeting the use requirements. When the heat-sealing plate 2 needs to be reset after heat-sealing, since the rising speed of the lifting plate 12 in the sliding groove 5 is slower than the rising speed of the heat-sealing plate 2 and the lifting mounting plate 3, when the heat-sealing plate 2 and the lifting mounting plate 3 rise and reset along the original path, when the hot-pressing contact surface of the heat-sealing plate 2 is higher than the scraper 31, the driving plate 19 will drive the column 13 to rotate, so that the two scrapers 31 are combined and attached again, and are located below the center line of the heat-sealing plate 2, waiting to remove the molten residues caused by excessive pressure or excessive pressure on the contact surface of the heat-sealing plate 2 during the next heat-sealing, improving the heat-sealing effect.
