Description

Technical Field

[0001] The invention relates to a heat-sealing splicing device, in particular to an anti-loosening heat-sealing splicing device and application thereof in diaper production. Background Art

[0002] The heat-sealing device heats the contact surfaces of the two materials to a molten state, and then applies a certain pressure to combine them together. At this time, the device needs to ensure that the joint maintains a certain stability during the merging process to prevent loosening or deformation from affecting the final joining effect. Anti-loose heat-sealing devices are usually used in industrial fields, such as in the processing of diapers, non-woven fabrics, films, plastics and other materials. Its main function is to prevent joint loosening or structural instability caused by temperature, pressure, mechanical force and other factors during the heat-sealing process.

[0003] When the current anti-loosening heat-sealing splicing device is used, especially when heat-sealing materials such as non-woven fabrics, the non-woven fabrics may leave impurities on the heat-sealing plate due to the high temperature. Non-woven fabrics are usually made of materials such as polypropylene (PP) and polyester (PET), which may melt, adhere or decompose at high temperatures. In particular, if the heat-sealing temperature is inappropriate or the heat-sealing time is too long, melted impurities will remain on the heat-sealing plate, which will affect the heat-sealing effect during the next heat-sealing process, resulting in the heat-sealing material partially failing to fully fuse, and the unheat-sealed material parts becoming loose. When cleaning impurities on the heat sealing plate of the device, after the heat sealing plate is completely raised and reset, an external driving device is used to drive the cleaning mechanism for cleaning impurities to clean the impurities on the heat sealing plate. During this cleaning process, the heat sealing plate needs to be completely raised and reset before the movement stroke of the cleaning mechanism can be satisfied, and the cleaning mechanism can clean the impurities on the surface of the heat sealing plate, resulting in a long downtime of the heat sealing machine. The cleaning mechanism needs to complete the entire cleaning movement stroke before it can operate, which causes a large amount of heat loss from the heat sealing plate, and consumes a lot of driving energy for generating heat from the heat sealing plate, which affects the heat sealing efficiency and increases the driving energy consumption of the heat sealing machine.

DETAILED DESCRIPTION

[0030] 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.

[0031] See also Figure 1~Figure 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; 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 mechanisms, a transmission mechanism connected to the mounting mechanisms and the lifting mechanisms, and a sliding cleaning mechanism connected to the transmission mechanism, wherein the transmission mechanism is connected to the lifting mounting plate 3, and a scraper 31 in the sliding cleaning mechanism is in sliding contact with the pressing contact surface of the heat-sealed plate 2; When the lifting installation plate 3 and the heat bonding plate 2 are lifted and lowered for heat bonding, the transmission mechanism is driven to operate. When the transmission mechanism operates, the sliding cleaning mechanism is driven to slide, so that the scraper 31 in the sliding cleaning mechanism slides and contacts the pressing contact surface of the heat bonding plate 2. When the transmission mechanism operates, the lifting mechanism is lifted and lowered in the installation mechanism to drive the sliding cleaning mechanism to lift and lower in conjunction with the heat bonding plate 2 and the lifting installation plate 3.

[0032] When the lifting and lowering of the lifting and lowering mounting plate 3 and the heat-sealing plate 2 is performed, the lifting and lowering mounting plate 3 can drive the transmission mechanism to move in a linked manner. When the transmission mechanism moves, the sliding cleaning mechanism can be slidably adjusted, so that the scraper 31 is abutted against the heat-sealing contact surface of the heat-sealing plate 2 and is scraped, so that the molten impurities remaining on the heat-sealing plate 2 are cleaned and collected by scraping. When the transmission mechanism is in action, the lifting and lowering mechanism can be slidably lifted and lowered on the mounting mechanism, so that the transmission mechanism and the sliding cleaning mechanism can be lifted and lowered in a linked manner following the lifting and lowering of the heat-sealing plate 2 and the lifting and lowering mounting plate 3. Through the coordinated design, the operating speed of the lifting and lowering mechanism is slower than the lifting and lowering speed of the heat-sealing plate 2 and the lifting and lowering 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 and lowering mounting plate 3. The design of the sliding cleaning mechanism can force the sliding cleaning mechanism to move downward under the downward pressure of the heat-sealing plate 2 and the lifting and lowering mounting plate 3, so as to meet the motion use. Through the design, the impurities remaining on the heat-sealing contact surface of the heat-sealing plate 2 can be cleaned. The heat sealing plate 2 is designed to prevent molten impurities from remaining on it, which may affect the subsequent heat sealing processing and use 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 the non-woven fabric to remain on the heat sealing plate 2, affecting the heat sealing effect in the next production process. It is also designed to avoid incomplete heat sealing due to residual impurities, which may cause the material to become loose and improve 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 higher temperature reacts with impurities in the air, carbon deposits or other contaminants may be generated on the heat sealing plate 2, which will affect the heat sealing quality and increase the cost of cleaning and maintenance. The heat sealing plate 2 and equipment should be cleaned regularly to remove residual materials or contaminants to avoid affecting subsequent production. Therefore, the scheme designs a structure that can perform self-cleaning 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.

[0033] See also Figure 5 , Figure 6 As a further solution of the present invention, the mounting mechanism includes an adjustment frame 4 fixedly mounted on the body 1 and two mounting rods 8 symmetrically fixedly connected to one side of the adjustment frame 4; The adjusting frame 4 is provided with a sliding groove 5 , and one end of the mounting rod 8 away from the adjusting frame 4 is rotatably connected to a second transmission wheel 10 . A first hexagonal hole 11 is provided at the center of the second transmission wheel 10 , and the first hexagonal hole 11 passes through the mounting rod 8 .

[0034] 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.

[0035] 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; 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; The lifting plate 12 is symmetrically connected with a transmission mechanism.

[0036] 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.

[0037] 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; 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; 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 .

[0038] 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.

[0039] See also Fig. 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; 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; 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.

[0040] 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.

[0041] See also Fig.10 , Fig.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; The second prism 24 is slidably inserted into the second hexagonal hole 18 opened at the bottom of the column 13. The top of the second prism 24 is fixedly connected to a limit block 26. The bottom end of the limit block 26 abuts against a spring 25. The spring 25 is sleeved on the second prism 24. The outer end of the spring 25 abuts against the inner wall of the second hexagonal hole 18. The two contact plates 22 are provided, and the two contact plates 22 are fixedly connected by a gear 23. The diameter of the two contact plates 22 is larger than the diameter of the gear 23, and the gear 23 is connected to the scratch assembly.

[0042] In this embodiment, since the lifting and lowering speed of the lifting plate 12 in the sliding groove 5 is slower than that of the heat bonding plate 2 and the lifting and mounting plate 3, when the heat bonding plate 2 and the lifting and mounting plate 3 descend, the heat bonding plate 2 will abut against the scratch assembly, forcing the scratch assembly to descend with it. At this time, the second prism 24 will be inserted into the second hexagonal hole 18. When the limit block 26 is close to the port distance of the second hexagonal hole 18, the spring 25 will be squeezed and contracted to maintain the rebound force. The insertion stroke of the second prism 24 in the second hexagonal hole 18 can compensate for the lowering stroke of the lifting plate 12 in the sliding groove 5 that is slower than that of the heat bonding plate 2 and the lifting and mounting plate 3, ensuring that the lowering operation of the heat bonding plate 2 and the lifting and 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 be linked to make the contact plate 22 and the gear 23 rotate, thereby meeting the rotation drive requirements for the scratch assembly and ensuring the linkage use effect.

[0043] See also Fig.12 As a further solution of the present invention, the scratching assembly includes a telescopic frame 27 and teeth 28 arranged on both sides of the telescopic frame 27; The tooth opening 28 meshes with the gear 23 , and the upper and lower sides of the telescopic frame 27 slide and fit between the two abutment plates 22 . The other side of the telescopic frame 27 is symmetrically fixedly connected with a mounting head 29 , and the mounting head 29 is connected to the collection assembly.

[0044] In this embodiment, the tooth mouth 28 is meshed with the gear 23, and the telescopic frame 27 is slidably connected between the two contact plates 22. The two contact plates 22 fit the upper and lower sides of the telescopic frame 27, so that the telescopic frame 27 can maintain horizontal movement and adjustment. Since a gear 23 is provided on both sides of the telescopic frame 27 to mesh with the tooth mouth 28, when the two gears 23 rotate synchronously in opposite directions, the telescopic frame 27 can be moved and adjusted to meet the drive adjustment requirements. By moving and adjusting the telescopic frame 27, the collecting component can slide in contact on the heat-sealing contact surface of the heat-sealing plate 2, so that the impurities remaining on the heat-sealing plate 2 can be removed, meeting the use requirements.

[0045] See also Fig.12As a further solution of the present invention, the collection component includes a collection frame 30 connected to two mounting heads 29 at both ends and a scraper 31 fixedly connected to the collection frame 30 on a side 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 material has a high melting point and excellent wear resistance. When the scraper 31 scrapes and cleans the heat-sealed contact surface of the heat-sealed plate 2, the force applied by the scraper 31 on the heat-sealed contact surface of the heat-sealed plate 2 and the sharpness of the scraper 31 will not cause the heat-sealed contact surface of the heat-sealed plate 2 to be scratched, and only the scraping and cleaning effect of impurities can be achieved, thereby avoiding scratching the heat-sealed contact surface of the heat-sealed plate 2 and ensuring the long-term use of the heat-sealed plate 2; The scraper 31 is arranged in a right-angled triangle shape, and two sides of the right-angled side of the scraper 31 overlap with two sides of the right-angled side of the top of the collecting frame 30 away from the telescopic frame 27 respectively.

[0046] In this embodiment, both sides of the machine body 1 are provided with a collecting assembly and various components connected to the collecting assembly. When the heat-sealing plate 2 and the lifting and mounting plate 3 are raised to the original position after heat-sealing, the two scrapers 31 will be in contact with each other, and the two scrapers 31 are located at the middle line of the heat-sealing plate 2. Since the lifting and lowering speed of the lifting plate 12 in the sliding groove 5 is slower than the lifting and lowering speed of the heat-sealing plate 2 and the lifting and mounting plate 3, the two scrapers 31 are at a distance from the heat-sealing plate 2 at this time. When the heat-sealing plate 2 and the lifting and mounting plate 3 are lowered, there is a gap between the two scrapers 31. When the heat-sealed plate 2 is to be separated, the heat-sealed contact surface will contact the two scrapers 31. At this time, the lifting installation plate 3 will drive the driving plate 19 to descend, and the driving plate 19 will drive the column 13 to rotate. The gear 23 will drive the telescopic frame 27 to slide and adjust. At this time, the two scrapers 31 are gradually spaced apart under the sliding adjustment of the two telescopic frames 27, so that the two scrapers 31 are scraped synchronously to both sides at the middle line of the heat-sealed plate 2. When the scrapers 31 scrape the heat-sealed plate 2, the molten impurities remaining on the heat-sealed plate 2 can fall into the collection frame 30 for collection. The descending speed of the heat-sealing plate 2 and the lifting and 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 compensate for the fact that the scratch component and the collecting component are slower than the descending stroke of the heat-sealing plate 2 and the lifting and mounting plate 3, so it does not affect the descending movement of the heat-sealing plate 2 and the lifting and mounting plate 3. When the heat-sealing plate 2 is about to contact the heat-sealed material, the two scrapers 31 are at the edges of both ends of the heat-sealing plate 2. As the heat-sealing plate 2 and the lifting and mounting plate 3 are pressed downward, the convex circle 21 at the driving plate 19 will move to the vertical groove 17. Since the vertical groove 17 is vertically opened, when the convex circle 21 moves to the vertical groove 17, the column 13 will not rotate, so the lifting plate 12 will not be adjusted in the sliding groove 5. The telescopic frame 27 will not move between the two abutment plates 22. At this time, the scraper 31 moves to the two ends of the heat sealing plate 2, which will not affect the downward pressing heat sealing operation of the heat sealing plate 2, and meets the use requirements. When the heat sealing plate 2 needs to be reset after the heat sealing is completed, since 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 and the lifting installation plate 3 are lifted and reset in the original way, 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 merged and fitted again, and are located below the center line of the heat sealing plate 2, waiting for the next heat sealing, the molten residue caused by excessive pressure or excessive pressure on the contact surface of the heat sealing plate 2 is cleared, thereby improving the heat sealing effect.

[0047] The application of the anti-loosening heat-sealing splicing device as described above in the production of diapers.

[0048] The above embodiments are exemplary rather than restrictive, so the technical solutions of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention are all included in the present invention.
