Description

Technical Field

[0001] This utility model relates to the field of nonwoven bag production technology, and in particular to a fully automatic ultrasonic welding device for nonwoven bags. Background Technology

[0002] Ultrasonic welding is used in non-woven bags primarily to efficiently, firmly, aesthetically pleasingly, and environmentally friendly replace traditional sewing. Through high-frequency vibration, the non-woven fabric material is instantly fused together, achieving production efficiency far exceeding that of sewing and significantly reducing production costs. Simultaneously, this process creates a completely sealed seam, giving the bag excellent waterproof and dustproof properties, and its seam strength is close to that of the material itself, making it exceptionally strong and durable. The welding process can also simultaneously complete cutting and edge sealing, resulting in smooth edges without burrs or loose threads, and a cleaner, more upscale appearance. Furthermore, the entire process requires no sewing thread or adhesive, consuming only electricity, perfectly aligning with the environmentally friendly positioning of non-woven bags, making it an advanced manufacturing process that integrates high efficiency, strength, sealing, aesthetics, and sustainability.

[0003] Currently, welding of non-woven bags in the market often relies on manual welding. This method is not only inefficient but also poses a risk of injury to workers during the welding process, such as the welding rollers coming into contact with the worker's hands. Furthermore, manual welding results in poor alignment of the non-woven fabric, often leading to misalignment and wasted fabric. Therefore, there is an urgent need for a fully automated ultrasonic welding device for non-woven bags to solve the technical problem of poor welding results due to low alignment of the non-woven fabric during welding in existing technologies. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fully automatic ultrasonic welding device for nonwoven bags.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic ultrasonic welding device for non-woven bags includes a base, on which a processing table is fixedly mounted. A fixed plate is fixedly mounted on the left side of the processing table, and a movable plate is movably mounted on the right side of the processing table. A sliding plate is slidably connected to the movable plate. Clamping components are provided on both the sliding plate and the fixed plate. A sliding table is fixedly mounted on the processing table, and a welding table is slidably connected inside the sliding table. An ultrasonic component is fixedly mounted inside the welding table, and a welding wheel is provided inside the ultrasonic component.

[0006] Preferably, the clamping assembly includes a first motor, the output end of the first motor is fixedly connected to a rotating block, a movable magnetic block is movably disposed at the upper end of the rotating block, and a movable electromagnetic block is fixedly installed at the lower end of the rotating block.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-10An automatic ultrasonic welding device for non-woven bags includes a base 1, a processing table 2 fixedly mounted on the base 1, a fixed plate 3 fixedly mounted on the left side of the processing table 2, a movable plate 4 movably mounted on the right side of the processing table 2, a sliding plate 7 slidably connected to the movable plate 4, and clamping components 5 on both the sliding plate 7 and the fixed plate 3. A slide table 12 is fixedly mounted on the processing table 2, a welding table 13 slidably connected inside the slide table 12, an ultrasonic component 14 fixedly mounted inside the welding table 13, and a welding wheel 15 inside the ultrasonic component 14. The clamping component 5 includes a first motor 51, a rotating block 52 fixedly connected to the output end of the first motor 51, a movable magnet 53 movably mounted on the upper end of the rotating block 52, and a movable electromagnetic block 54 fixedly mounted on the lower end of the rotating block 52. Several dampers 9 are installed between the lower end of the sliding plate 7 and the movable plate 4. A clamping magnetic block 8 is fixedly and movably installed inside the sliding plate 7. The clamping magnetic block 8 cooperates with the movable magnetic block 53 to clamp the right end of the non-woven fabric on the processing table 2. The sliding plate 7 is made of metal capable of attracting the clamping magnetic block 8. Two connecting blocks 11 are fixedly installed on the left side of the fixed plate 3, one of which is fixedly connected to the output end of the second motor 10. A fixed electromagnetic block 6 is fixedly installed inside the fixed plate 3. The fixed electromagnetic block 6 cooperates with the movable magnetic block 53 to clamp the left end of the non-woven fabric on the processing table 2. The clamping assembly 5 can clamp both ends of the non-woven fabric, keeping them aligned. Rotating the movable plate 4 applies pressure to the non-woven fabric, keeping it flat and ensuring stability during subsequent welding.

[0017] Two symmetrically arranged fixing blocks 16 are rotatably connected to both ends of the welding wheel 15. The fixing blocks 16 are fixedly installed on the welding table 13. A bevel gear set 18 is rotatably arranged inside the fixing blocks 16. One end of the bevel gear set 18 is fixedly connected to one end of the welding wheel 15, and the other end of the bevel gear set 18 is fixedly connected to a friction wheel 17. The other end of the friction wheel 17 is rotatably connected to the inner wall of the welding table 13. By cooperating with the welding wheel 15, the tensile force on the nonwoven fabric during welding can be reduced, avoiding deformation of the nonwoven fabric due to stretching during welding, thereby reducing the offset of the nonwoven fabric during welding and avoiding material waste.

[0018] In this invention, when ultrasonic welding is required on the non-woven bag, a long strip of non-woven fabric is placed on the upper end of the fixed plate 3 and the movable plate 4, so that the center line of the non-woven fabric is kept at the junction of the fixed plate 3 and the movable plate 4.

[0019] After the nonwoven fabric is placed, the two sets of first motors 51 are started respectively, so that the output shafts of the two sets of first motors 51 rotate in the direction from the outside to the inside. The rotation of the first motor 51 will drive the rotating block 52 to rotate coaxially through the output shaft. The rotation of the rotating block 52 will drive the movable magnetic block 53 to move synchronously. When the movable magnetic block 53 contacts the nonwoven fabric, the rotation of the first motor 51 is stopped, and then the movable electromagnetic block 54 is turned off, so that the movable electromagnetic block 54 releases the restriction on the movable magnetic block 53. At this time, the movable electromagnetic block 54 no longer exerts an attraction on the movable magnetic block 53. Then, the fixed electromagnetic block 6 fixedly installed on the fixed plate 3 is started, so that the fixed electromagnetic block 6 exerts an attraction on the movable electromagnetic block 54 on the fixed plate 3, thereby making the movable electromagnetic block 54 and the fixed electromagnetic block 6 cooperate to clamp one end of the nonwoven fabric. Since the sliding plate 7 inside the movable plate 4 is equipped with a clamping magnetic block 8, when the movable electromagnetic block 54 on the movable plate 4 releases the restriction on the movable magnetic block 53, the movable magnetic block 53 on the movable plate 4 will cooperate with the clamping magnetic block 8 to form a clamping effect on the other end of the non-woven fabric. At this time, both ends of the non-woven fabric are clamped respectively.

[0020] Then, the second motor 10 is started, so that the output end of the second motor 10 drives the movable plate 4 to rotate along the axis of the output end of the second motor 10 through the connecting block 11. At this time, since both ends of the non-woven fabric are clamped, the non-woven fabric will not shift during the flipping process. Furthermore, since the movable plate 4 is equipped with a sliding plate 7 and the lower end of the sliding plate 7 is fixedly connected to a damper 9, when the movable plate 4 is in contact with the fixed plate 3, the sliding plate 7 can slide along the inner wall of the movable plate 4 when it is resisted, so that the non-woven fabric can be flatly attached to the surface of the fixed plate 3. When the movable plate 4 and the fixed plate 3 are fully attached, the attractive force of the fixed electromagnetic block 6 is increased. At this time, both the movable magnetic block 53 and the clamping magnetic block 8 on the movable plate 4 are attracted by the fixed electromagnetic block 6. This drives the second motor 10 to reset, causing the movable plate 4 to reset. Because the movable magnetic block 53 and the clamping magnetic block 8 are attracted by the fixed electromagnetic block 6, the movable plate 4 separates from the clamping magnetic block 8 during reset. At this point, the clamping magnetic block 8 adheres to the two sets of movable magnetic blocks 53 and remains on the non-woven fabric, forming a clamping effect. This allows the non-woven fabric to remain aligned before ultrasonic welding, improving the welding effect while reducing waste of non-woven fabric material.

[0021] After the nonwoven bag is clamped by the clamping magnetic block 8, two sets of movable magnetic blocks 53 and fixed electromagnetic block 6, the welding table 13 is activated, causing the welding table 13 to slide along the inner wall of the slide table 12 to adjust the welding position. When the welding table 13 reaches the welding position, the ultrasonic component 14 is activated, causing the ultrasonic component 14 to generate high-frequency vibration on the welding wheel 15. At this time, the nonwoven fabric can be welded. During welding, the welding wheel 15 rolls along the edge of the nonwoven fabric to perform ultrasonic welding. When the welding wheel 15 rolls along the surface of the nonwoven fabric, the welding wheel 15 will drive the friction wheel 17 to rotate in the opposite direction of the rolling direction of the welding wheel 15 through the bevel gear set 18. Since the nonwoven fabric is relatively soft, the welding wheel 15 will stretch the nonwoven fabric to a certain extent during welding, which will lead to welding deviation. By rotating the friction wheel 17 in the opposite direction of the rolling direction of the welding wheel 15, the stretching force generated by the rolling of the welding wheel 15 can be offset, thereby keeping the nonwoven fabric flat during welding and further improving the welding effect.

[0022] Once the nonwoven bag is welded, simply return the movable magnetic block 53 and the clamping magnetic block 8 to their original positions to proceed with the next welding operation.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
