Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing, and in particular to a nonwoven fabric composite device. Background Technology

[0002] Nonwoven fabric composite equipment plays an important role in industrial production and is widely used in fields such as medical and health care, packaging, and agriculture. The core function of this equipment is to bond multiple layers of nonwoven fabric materials together with adhesives to form composite nonwoven fabric products with specific properties.

[0003] In the nonwoven fabric lamination process, the adhesive coating process is a crucial step in ensuring the quality of the composite material. However, existing nonwoven fabric adhesive coating devices generally suffer from a fixed coating height, meaning the distance between the coating head and the nonwoven fabric is preset and cannot be adjusted. Since the thickness of the multi-layered nonwoven fabric varies, the fixed coating height leads to uneven adhesive application when the nonwoven fabric thickness changes. Thicker areas may receive too little adhesive, while thinner areas may receive too much, even resulting in adhesive overflow. This not only wastes adhesive but also affects the strength and appearance of the composite material. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a nonwoven fabric composite device. By moving the components, the device can be flexibly and precisely adjusted according to the thickness of the nonwoven fabric, ensuring that the coating roller and the nonwoven fabric always maintain the optimal gap, thereby achieving uniform adhesive coating.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nonwoven fabric composite device, including a base, a support frame fixedly connected to the top of the base, a first motor fixedly connected to the right end of the support frame, guide rollers rotatably connected to both the front and rear sides of the inner wall of the support frame, the right end of the rear guide roller fixedly connected to the drive end of the first motor, the left ends of the two guide rollers connected by a belt, a connecting rod rotatably connected inside the support frame, a first gear fixedly connected to the left end of the connecting rod, a moving component provided on the outer wall of the first gear, the first gear displacing the glue storage box through the moving component, and a squeezing chamber fixedly connected to the front end of the support frame, the squeezing chamber being used to cause the glued nonwoven fabric to fall and be stacked.

[0006] Furthermore, the moving component includes a toothed plate meshing with the outer wall of the first gear, a slide rod fixedly connected to the outer wall of the toothed plate, and a glue storage box fixedly connected to the inner wall of the slide rod. The glue storage box is used to hold the adhesive liquid, and the outer wall of the glue storage box slides within the inner wall of the base.

[0007] Furthermore, a second gear is fixedly connected to the right end of the connecting rod, and another toothed plate is meshed with the outer wall of the second gear. The opposite ends of the two toothed plates are used together to ensure the sliding stability of the glue storage box.

[0008] Furthermore, an adhesive applicator roller is rotatably connected to the inner wall of the support frame, with the bottom end of the adhesive applicator roller corresponding to the top end of the adhesive storage box, and the right ends of the adhesive applicator roller and the guide roller are connected by a belt.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3This utility model provides an embodiment of a nonwoven fabric composite device, including a base 1, a support frame 2 fixedly connected to the top of the base 1, a first motor 3 fixedly connected to the right end of the support frame 2, guide rollers 4 rotatably connected to both the front and rear sides of the inner wall of the support frame 2, the right end of the rear guide roller 4 fixedly connected to the drive end of the first motor 3, the left ends of the two guide rollers 4 connected by a belt, a connecting rod 17 rotatably connected inside the support frame 2, a first gear 7 fixedly connected to the left end of the connecting rod 17, and the outer wall of the first gear 7 being provided with... A movable component is provided, through which the first gear 7 moves the glue storage box 15. The movable component includes a toothed plate 8 meshing with the outer wall of the first gear 7. A slide rod 16 is fixedly connected to the outer wall of the toothed plate 8, and the glue storage box 15 is fixedly connected to the inner wall of the slide rod 16. The glue storage box 15 is used to hold the glue liquid. The outer wall of the glue storage box 15 slides within the inner wall of the base 1. A second gear 18 is fixedly connected to the right end of the connecting rod 17. Another toothed plate 8 is meshing with the outer wall of the second gear 18. The opposite ends of the two toothed plates 8 are used together for... To ensure the sliding stability of the glue storage box 15, a glue application roller 19 is rotatably connected to the inner wall of the support frame 2. The bottom end of the glue application roller 19 corresponds to the top end of the glue storage box 15. The glue application roller 19 and the right end of the guide roller 4 are connected by a belt. The two guide rollers 4 are also connected by a belt. When the first motor 3 drives the rear guide roller 4 to rotate, the rear guide roller 4 drives the front guide roller 4 to rotate synchronously. At the same time, the rear guide roller 4 drives the glue application roller 19 to rotate via the belt, so that the glue application roller 19 and the guide roller 4 rotate synchronously. To ensure that the relative speed between the nonwoven fabric and the coating roller 19 and guide roller 4 is moderate during the coating process, and to avoid adhesion due to excessive speed or slow speed, the outer wall of the guide roller 4 is made of polytetrafluoroethylene, so that even if the front guide roller 4 is contaminated by the coating roller 19, the nonwoven fabric will not stick to the guide roller 4. The left end of the support frame 2 is fixedly connected to the second motor 5, and the drive end of the second motor 5 is fixedly connected to the turntable 6. The turntable 6 and the connecting rod 17 are connected by a belt. The second motor 5 is used to drive the first gear 7 to rotate.

[0024] Specifically, a piece of nonwoven fabric is placed in the extrusion chamber 9 as the bottom layer material for lamination. Then, the first motor 3 is started, which drives the rear guide roller 4 to rotate. The rotation of the guide roller 4 drives the coating roller 19 to rotate via the belt on the right side, and simultaneously drives the front guide roller 4 to rotate via the belt on the left side, forming a continuous material conveying state. At this time, the nonwoven fabric to be laminated can be placed on the rear guide roller 4. The rotation of the rear guide roller 4 pushes the nonwoven fabric through the coating roller 19, so that the adhesive on the coating roller 19 is evenly applied to the surface of the nonwoven fabric. Then, the nonwoven fabric passes through the front guide roller 4 and enters the extrusion chamber 9 through the inlet. In step 9, the coating material falls onto the pre-placed non-woven fabric, achieving the initial superposition of two layers of non-woven fabric. Then, based on the thickness of the placed non-woven fabric, the second motor 5 is started, driving the turntable 6 to rotate. The rotation of the turntable 6 pulls the belt, which transmits force to the connecting rod 17, causing the connecting rod 17 to rotate. The rotation of the connecting rod 17 drives the first gear 7 and the second gear 18 on the left and right sides to rotate, thereby causing the toothed plate 8 to move up or down. Then, the movement of the toothed plate 8 is transmitted through the slide rod 16 to the glue storage box 15 containing the coating liquid, causing the distance between the glue storage box 15 and the coating roller 19 to change, ensuring that the coating liquid can be applied evenly and avoiding glue accumulation or missed coating.

[0025] Reference Figure 1 and Figure 4 The front end of the support frame 2 is fixedly connected to the extrusion chamber 9, which is used to drop and stack the non-woven fabric after the adhesive coating is applied. The upper and lower sides of the left end of the extrusion chamber 9 are fixedly connected to the clips 12. The outer wall of the clips 12 is fitted with buckles 13. The outer wall of the buckles 13 is fixedly connected to the cover 10. The right end of the cover 10 is rotatably connected to the hinge 14. The outer wall of the hinge 14 is fixedly connected to the right end of the extrusion chamber 9. The top end of the extrusion chamber 9 is fixedly connected to the hydraulic cylinder 11. The driving end of the hydraulic cylinder 11 passes through the extrusion chamber 9 and is fixedly connected to the cover plate 20. The inside of the cover plate 20 is equipped with heating elements. The cover plate 20 is used to heat and press the non-woven fabric to be laminated.

[0026] Specifically, after the nonwoven fabric has been stacked to the appropriate number of layers, the first motor 3 and the second motor 5 are turned off to stop the material conveying and gluing operations. The hydraulic cylinder 11 is activated to drive the cover plate 20 to move downwards. At the same time, the heating element in the cover plate 20 is opened to heat and press the nonwoven fabric, completing the curing of the nonwoven fabric and making the multiple layers of nonwoven fabric firmly bonded together. After the lamination is completed, the clamp 12 is pressed to release the clamp 13 from its restriction. Then, the cover 10 is pressed to rotate on the hinge 14, opening the interior of the extrusion chamber 9 and exposing the laminated nonwoven fabric inside, making it easy for the operator to remove it.

[0027] Working principle: Take out a piece of non-woven fabric and place it in the extrusion chamber 9. Then start the first motor 3 to drive the rear guide roller 4 to rotate. The guide roller 4 drives the coating roller 19 to rotate via the belt on the right side and drives the front guide roller 4 to rotate via the belt on the left side. Then, the non-woven fabric to be laminated can be placed on the rear guide roller 4. The rear guide roller 4 pushes the non-woven fabric through the coating roller 19 to apply glue, and then through the front guide roller 4 into the extrusion chamber 9 from the inlet of the extrusion chamber 9, and falls onto the non-woven fabric that was placed beforehand.

[0028] Then, based on the thickness of the nonwoven fabric, the second motor 5 is started, driving the turntable 6 to rotate. The turntable 6 pulls the belt, which transmits force to the connecting rod 17, causing the connecting rod 17 to rotate. The connecting rod 17 then rotates the first gear 7 and the second gear 18 on both sides. The rotation of the first gear 7 and the second gear 18 causes the toothed plate 8 to move up or down. The toothed plate 8 moves the glue storage box 15 containing the adhesive liquid up or down via the slide rod 16, changing the distance between the glue storage box 15 and the glue coating roller 19 to ensure that the adhesive liquid can be applied evenly.

[0029] Then, after reaching the appropriate number of layers, turn off the first motor 3 and the second motor 5, and then start the hydraulic cylinder 11. At the same time, the hydraulic cylinder 11 drives the cover plate 20 to move downward, and opens the heating plate in the cover plate 20, so that the cover plate 20 heats and presses the non-woven fabric to complete the curing of the non-woven fabric. After the composite is completed, press the clip 12 to release the clip 13 from the restriction, and then press the cover 10 to make it rotate on the hinge 14 to unfold the inside of the extrusion chamber 9 and take out the composite non-woven fabric.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
