Description

Technical Field

[0001] This utility model relates to the field of spunlace nonwoven fabric processing technology, specifically to an adhesive device for the composite process of spunlace nonwoven fabric. Background Technology

[0002] As is well known, the principle of hydroentangling for reinforcing fiber webs is similar to that of needle punching, but instead of needles, it uses high-pressure multi-jet micro-water jets to spray the fiber web. After passing through the fiber web, the water jets are rebounded by the support curtain and penetrate the fiber web again. Thus, under the hydraulic action of the high-speed water jets penetrating in different directions, the fibers in the fiber web undergo displacement, penetration, entanglement, and cohesion, thereby entangled the fibers together and reinforcing the fiber web to a certain strength. The resulting fabric is hydroentangled nonwoven fabric. Its fiber raw materials are widely available, including polyester, nylon, polypropylene, viscose fiber, chitosan fiber, microfiber, Tencel, silk, bamboo fiber, wood pulp fiber, and seaweed fiber, etc. A bonding machine is required in the composite production of hydroentangled nonwoven fabrics. However, the bonding machines in the existing technology are not convenient for adjusting the height of the pressure rollers and are not convenient for handling and moving. Therefore, we propose a bonding machine for the composite process of hydroentangled nonwoven fabrics.

[0003] To solve the above-mentioned technical problems, Chinese Patent No. CN220450434U discloses a bonding machine for the composite process of spunlace nonwoven fabric, which includes a substrate, an adjustment box fixedly installed on the right side of the top of the substrate, a stepper motor fixedly installed at the bottom of the inner cavity of the adjustment box, a one-way threaded rod fixedly installed on the output shaft of the stepper motor, and a screw block threadedly connected to the surface of the one-way threaded rod.

[0004] While the aforementioned existing technical solutions, by setting conveyor rollers, can apply pressure to the fabric, effectively bond the fibers inside the fabric, and ensure the flatness of the bonded fabric with a short bonding time, thus effectively improving production efficiency, their heating plates and heat-conducting plates are directly fixed in the inner cavity of the substrate, and as such... Figure 1 and Figure 2 As shown, the position adjustment of its support box is limited, and therefore the above factors prevent workers from quickly replacing the aging and damaged heating plate and heat conduction plate, which in turn affects work efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figures 1-3 This utility model provides a technical solution:

[0022] A bonding device for a spunlace nonwoven fabric lamination process includes a base 1. Support feet are installed at the bottom corners of the base 1. A placement groove is formed on the top of the base 1, and a heating plate 2 overlaps inside the placement groove. A heat-conducting plate 3 is installed on one side of the heating plate 2. A fixing frame 4 is installed on one side of the outer wall of the base 1, and a movable pressing mechanism is installed on the fixing frame 4. The heat-conducting plate 3 is engaged with the base 1 via a locking mechanism. The locking mechanism includes a pressing component, a pulling component, and a protective component. The pressing component locks the positions of the heating plate 2 and the heat-conducting plate 3, the pulling component unlocks the heating plate 2 and the heat-conducting plate 3, and the protective component... The protective component is used to protect the operating parts of the pressing assembly. During use, the heating plate 2 and the heat-conducting plate 3 can be locked in position by the pressing assembly, and the heating plate 2 and the heat-conducting plate 3 can be unlocked by the pulling assembly. The protective component protects the operating parts of the pressing assembly. The structure is simple and easy to operate. The operator can quickly disassemble the heating plate 2 and the heat-conducting plate 3 for inspection and maintenance according to the actual situation. It can also avoid the pressure roller 23 pressing down too fast. While applying a certain force to the fabric, it avoids the pressure roller 23 from damaging the fabric, the heat-conducting plate 3 and the heating plate 2, further improving work efficiency and the practicality of the device.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the pressing assembly includes overlapping plates 5 installed on both ends of the outer wall of the heat-conducting plate 3. The top of the base 1 has overlapping grooves on both sides of the placement groove that are slidably connected to the overlapping plates 5. A rubber pad 6 is embedded in the bottom end of the overlapping plate 5. A through hole is opened at one end of the rubber pad 6. A pressure block 7 is installed at the through hole at the bottom end of the overlapping plate 5. First, during installation and use, the heating plate 2 and the heat-conducting plate 3 can be placed inside the placement groove, so that the rubber pad 6 on the overlapping plate 5 contacts the inner wall of the overlapping groove and the rubber pad 6 is pressed down. At the same time, the pressure block 7 will enter the inner side of the pressure groove and contact the reset plate 8, so that the inclined surfaces 10 on the two opposite ends fit together, forcing the reset plate 8 to compress the two sets of first springs 9 to retract.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the base 1 has a pressure groove on one side of the overlapping groove that is slidably connected to the pressure block 7. A reset groove is also provided on one side of the pressure groove inside the base 1. A reset plate 8 is slidably connected inside the reset groove. First springs 9 are installed between both ends of one side of the reset plate 8 and the inner wall of the reset groove. The protruding ends of the reset plate 8 and the pressure block 7 both have mutually fitting inclined surfaces 10. The pressure block 7 has an L-shaped cross-section, and the reset plate 8 has a T-shaped cross-section. The protective assembly includes an extension plate 14 slidably connected to the inner side of the extension groove. The extension plate 14 is hinged to the outer wall of the base 1 via a hinge. One end of the extension plate 14... A magnetic block 15 is embedded in the extension groove, and an iron block that attracts the magnetic block 15 is embedded in the inner wall of the extension groove. A first latching groove is opened on one side of the extension plate 14, and a second latching groove is opened on the top of the overlapping plate 5. Then, after the pressure block 7 is fully pushed into the pressure groove, the two sets of first springs 9 can drive the reset plate 8 to pop out and abut against the other side of the protruding end of the pressure block 7, locking the position of the heating plate 2 and the heat-conducting plate 3. After locking, the extension plate 14 can be flipped with the hinge to lock it into the extension groove. The magnetic block 15 will attract the iron block and temporarily position it, thereby protecting the pull ring 13 to prevent accidental contact.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the pull assembly includes a movable rod 11 installed on one side of the reset plate 8 between two sets of first springs 9. An extension groove is provided on the outer wall of the base 1 below the overlapping groove. A pull plate 12 is installed at one end of the extension groove of the movable rod 11. A second spring is installed between the pull plate 12 and the inner wall of the extension groove. A pull ring 13 is rotatably connected to one end of the outer wall of the pull plate 12 near the movable rod 11. Furthermore, when repairing and maintaining the aged and damaged heating plate 2 and heat-conducting plate 3, the pull ring 13 can be fastened to move the movable rod 11 and the pull plate 12, compressing the second spring while stretching the first spring 9, so that the reset plate 8 moves away from the pressure block 7. At this time, the rubber pad 6 loses pressure and rebounds instantly, causing the pressure block 7 to move upward. At this time, releasing the pull ring 13 will not cause it to snap again. Fastening the second pull groove can drive the two sets of overlapping plates 5 together with the heat-conducting plate 3 and the heating plate 2 to be taken out.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the movable pressing mechanism includes an adjustment groove on one side of the inner wall of the fixed frame 4. A threaded rod 16 is rotatably connected to the inner side of the adjustment groove, and an adjustment plate 17 is threadedly connected to the outer side of the threaded rod 16. A retraction frame 18 is installed on one side of the adjustment plate 17. A motor 19 is installed at one end of the top of the fixed frame 4. The drive end of the motor 19 extends to the inner side of the adjustment groove and is fixedly connected to one end of the threaded rod 16. The retraction frame 18 has a U-shaped cross-section. Sliding grooves are provided on both sides of the inner wall of the retraction frame 18. Sliding blocks are slidably connected to the inner side of the sliding grooves. The cross-sections of the sliding grooves and the sliding blocks are both T-shaped. A pressing plate 21 is installed between the two sets of sliding blocks. The pressing plate 21 and the retraction frame... A third spring 20 is installed between the inner walls of the 18. A connecting plate is installed at the bottom of the lower pressure plate 21. A movable frame 22 is installed at the other end of the connecting plate. Multiple sets of pressure rollers 23 are rotatably connected inside the movable frame 22. Furthermore, during processing, the motor 19 can be started to drive the threaded rod 16 to rotate, so that the adjusting plate 17 drives the retraction frame 18 to move closer to the fabric direction until the pressure rollers 23 are pressed on the fabric surface. When the pressure rollers 23 move too fast or move down too far, the lower pressure plate 21 can cooperate with the sliding groove and sliding block to slide inside the retraction frame 18 and squeeze the third spring 20 to a certain extent to avoid damage to the fabric, the heat-conducting plate 3, and the heating plate 2.

[0027] The implementation principle of the bonding device for the composite process of spunlace nonwoven fabric in this application embodiment is as follows: During installation and use, the heating plate 2 and the heat-conducting plate 3 can be placed inside the placement groove, so that the rubber pad 6 on the overlapping plate 5 contacts the inner wall of the overlapping groove and is pressed downward. At the same time, the pressure block 7 will enter the inner side of the pressure groove and contact the reset plate 8, so that the inclined surfaces 10 on the two opposite ends are in contact with each other, forcing the reset plate 8 to compress the two sets of first springs 9 to retract. After the pressure block 7 is fully pushed into the inner side of the pressure groove, the two sets of first springs 9 can drive the reset plate 8 to pop out and abut against the other side of the protruding end of the pressure block 7, locking the position of the heating plate 2 and the heat-conducting plate 3. After locking, the extension plate 14 can be flipped with the hinge to engage with the extension groove. The magnetic block 15 will be attracted to the iron block and temporarily positioned, thereby protecting the pull ring 13 to prevent accidental contact. When the hot plate 3 is being inspected and maintained, the pull ring 13 can be fastened to move the movable rod 11 and the pull plate 12, compressing the second spring while stretching the first spring 9, causing the reset plate 8 to move away from the pressure block 7. At this time, the rubber pad 6 loses pressure and rebounds instantly, causing the pressure block 7 to move upward. At this time, releasing the pull ring 13 will not cause it to lock again. Fastening the second pull groove can drive the two sets of overlapping plates 5 together with the heat-conducting plate 3 and the heating plate 2 to be taken out. During processing, the motor 19 can be started to drive the threaded rod 16 to rotate, causing the adjusting plate 17 to drive the retraction frame 18 to move closer to the fabric direction until the pressure roller 23 is pressed on the fabric surface. When the pressure roller 23 moves too fast or moves too far down, the lower pressure plate 21 can cooperate with the sliding groove and sliding block to slide inside the retraction frame 18 and squeeze the third spring 20 to a certain extent to avoid damage to the fabric, heat-conducting plate 3 and heating plate 2.

[0028] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
