Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing equipment, in particular to a hot air non-woven fabric ultrasonic pressing mechanism. Background Art

[0002] Hot air non-woven fabric can be used as the surface layer, bottom layer and lining in diapers. The ultrasonic pressing mechanism of hot air non-woven fabric is a key component of diaper production equipment. It uses the high-frequency vibration waves of ultrasound to press the hot air non-woven fabric with other diaper rolls (such as water-absorbing layer, guide layer, etc.) to form diaper products with specific structure and function. The mechanism generates high-frequency vibration waves through an ultrasonic generator, and these vibration waves are transmitted to the pressing roller. In the process of contact between the ultrasonic generator and the hot air non-woven fabric and other materials, the high-frequency vibration waves cause frictional heat to be generated on the surface of the material, thereby causing the material molecules to fuse. By using ultrasonic fusion technology, the hot air non-woven fabric can be tightly combined with other materials, thereby improving the sealing of diapers and preventing urine leakage.

[0003] Based on the above situation, in the prior art, the patent application number CN202420348877.9 discloses an ultrasonic welding mechanism for diapers, including a clamping roller and a welding unit. The clamping rollers are arranged in pairs for clamping the diaper roll. The welding unit includes a transducer connected to an external ultrasonic vibration device, a rotating shaft, a roller and a support roller. The rotating shaft is laterally arranged on the side of the transducer and is an integrated structure with the transducer. The roller is sleeved on the rotating shaft. The support roller is rotatable below the roller. The transducer is arranged on both sides of the support roller. The side of the support roller is formed with a strip-shaped depression centered on the axis of the support roller. The roller of the welding unit cooperates with the support roller to achieve continuous welding of the diaper roll during the conveying process. During the process, no moving mechanism is required to drive the transducer to move, which helps to maintain consistent welding force. At the same time, the strip gap on the roller can avoid the welding part from forming a continuous weld line, which can avoid the diaper from becoming hard and affecting the wearing comfort.

[0004] However, there are still some deficiencies in the process of pressing diaper rolls together by the above-mentioned welding mechanism. The ultrasonic welding mechanism in the prior art does not provide the function of automatically adjusting the height between the roller and the support roller to adapt to diaper rolls of different thicknesses. This lack of automatic adjustment capability may result in poor pressing effect between diaper rolls, such as incomplete pressing or excessive pressing. At the same time, during the ultrasonic pressing process, the roller vibrates at high frequency, causing the roller to heat up. If the heat cannot be effectively dissipated, the service life of the roller used for ultrasonic pressing will be reduced. Utility Model Content

The implementation of the present invention is not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0024] like Figures 1 to 7As shown, the utility model provides a technical solution, a hot air non-woven fabric ultrasonic laminating mechanism, comprising a frame 1, the frame 1 is provided with an installation box 11, the top of the installation box 11 is connected to a V-shaped installation frame 12, the V-shaped installation frame 12 is internally installed with an ultrasonic laminating assembly 2 with a bilaterally symmetrical layout, the ultrasonic laminating assembly 2 comprises an ultrasonic laminating component 21 and an adjusting component 22, the adjusting component 22 is fixedly connected to the V-shaped installation frame 12, the ultrasonic laminating component 21 is fixedly connected to the adjusting component 22, a laminating bottom roller 3 is rotatably installed in the installation box 11, the laminating bottom roller 3 is arranged below the ultrasonic laminating component 21, a material receiving plate 5 is provided between the ultrasonic laminating component 21 and the laminating bottom roller 3, a cooling air duct 6 and a cooling air knife 4 are provided above the material receiving plate 5, the cooling air duct 6 is arranged between the ultrasonic laminating components 21 and is fixedly installed on the inner wall of the installation box 11.

[0025] The ultrasonic pressing assembly 2 of the present invention is installed in a symmetrical V-shape on the V-shaped mounting frame 12. The V-shaped layout not only optimizes space utilization, but also makes the pressing process more efficient. The two-side pressing works at the same time, which can effectively improve production efficiency. The adjustment component 22 can accurately adjust the height between the ultrasonic pressing head 215 and the pressing bottom roller 3 through the cooperation between the fixed plate 221, the sliding plate 222, the screw rod 223 and the lifting motor 224, so that the ultrasonic pressing mechanism can adapt to hot air non-woven fabrics and other diaper rolls of different thicknesses, thereby improving the flexibility and adaptability of the ultrasonic pressing mechanism. Adaptability; heat dissipation channels 216 are set through the left and right sides of the ultrasonic pressing head 215, which help to discharge the heat generated during the pressing process in time, prevent the ultrasonic pressing head 215 from overheating, and extend its service life; the cooling air duct 6 and the cooling air knife 4 together constitute a cooling structure on the left and right sides of the ultrasonic pressing head 215, and the cooling air duct 6 provides cooling airflow to the surrounding area of ​​the ultrasonic pressing head 215 through the first main air duct 62 and the first air outlet 63; the cooling air knife 4 blows cooling airflow directly to the ultrasonic pressing head 215 through the second main air duct 43 and the second blowing hole 44, further enhancing the heat dissipation effect.

[0026] As one of the preferred embodiments of the present invention, Figure 1 and Figure 2 As shown, an arc-shaped working surface 31 is symmetrically arranged on the upper and lower surfaces of the laminating bottom roller 3, a rotating shaft 32 is coaxially installed inside the laminating bottom roller 3, and a driving motor 33 is arranged outside the installation box 11. One end of the rotating shaft 32 is rotatably installed on the inner wall of the installation box 11, and the other end of the rotating shaft 32 passes through the side wall of one side of the installation box 11 and is connected to the power output shaft of the driving motor 33.

[0027] One end of the rotating shaft 32 is rotatably connected to the inner wall of the installation box 11, and the other end passes through the installation box 11 and is connected to the power output shaft of the external drive motor 33. When the drive motor 33 is started, it drives the pressing roller 3 to rotate via the rotating shaft 32. During the pressing process, the hot air non-woven fabric is placed on the material receiving plate 5 and enters the pressing area with traction. When the curved working surface 31 of the pressing roller 3 rotates to the bottom of the ultrasonic pressing head 215, a pressing point is formed. At this time, the ultrasonic pressing head 215 emits ultrasonic vibrations, which are transmitted between the curved working surface 31 of the pressing roller 3 and the hot air non-woven fabric through the horn 214, forming a pressing effect.

[0028] At the same time, the curved working surface 31 can fit tightly with the lower surface of the ultrasonic pressing head 215 to ensure the uniformity and stability of the pressing point; different forms of concave and convex patterns can be set on the curved working surface 31, thereby forming a corresponding pattern effect when pressing the hot air non-woven fabric, increasing the aesthetics and added value of the product.

[0029] As one of the preferred embodiments of the present invention, Figure 1 and Figure 3 As shown, the adjusting component 22 includes a fixed plate 221, a sliding plate 222, a screw rod 223 and a lifting motor 224. The fixed plate 221 is tilted and mounted on the V-shaped side wall of the V-shaped mounting frame 12. A sliding groove 225 is provided on the surface of the fixed plate 221. The sliding plate 222 is slidably mounted in the fixed plate 221 through the sliding groove 225. The screw rod 223 is rotatably arranged inside the sliding plate 222. One end of the screw rod 223 is placed in the sliding groove 225 and is rotatably connected to the inner side wall of the fixed plate 221. The other end of the screw rod 223 passes through the fixed plate 221 and is connected to the lifting motor 224 arranged outside the fixed plate 221. The ultrasonic pressing component 2 1 includes a fixing frame 211, a mounting seat 212, a transducer 213, a horn 214, and an ultrasonic pressing head 215. The fixing frame 211 is mounted on the surface of the sliding plate 222. The lower end of the fixing frame 211 is connected to the mounting seat 212. The transducer 213 is connected to the fixing frame 211. The ultrasonic pressing head 215 is arranged in the mounting seat 212. Connecting strips 217 are provided on the left and right surfaces of the ultrasonic pressing head 215. The ultrasonic pressing head 215 is connected to the mounting seat 212 via the connecting strips 217. The transducer 213 and the ultrasonic pressing head 215 are connected via the horn 214. Heat dissipation channels 216 are provided on the left and right sides of the ultrasonic pressing head 215.

[0030] The fixed plate 221 is obliquely mounted on the V-shaped side wall of the V-shaped mounting frame 12, and a sliding groove 225 is provided on its surface. The sliding plate 222 is slidably mounted in the fixed plate 221 through the sliding groove 225, so that the sliding plate 222 can slide on the fixed plate 221; the screw rod 223 is rotatably arranged inside the sliding plate 222, one end of which is placed in the sliding groove 225 and rotatably connected to the inner side wall of the fixed plate 221, and the other end passes through the fixed plate 221 and is connected to the lifting motor 224 provided outside the fixed plate 221; when the lifting motor 22 When started, the lifting motor 224 drives the screw rod 223 to rotate. Due to the threaded engagement between the screw rod 223 and the sliding plate 222, when the screw rod 223 rotates, the sliding plate 222 moves up and down along the axis of the screw rod 223. By controlling the rotation direction and speed of the lifting motor 224, the height of the sliding plate 222 and the ultrasonic laminating component 21 mounted thereon can be accurately adjusted. Thus, the operator can adjust the gap between the ultrasonic laminating head 215 and the laminating bottom roller 3 according to actual needs to meet the laminating requirements of materials of different thicknesses.

[0031] The ultrasonic pressing component 21 is mainly composed of a fixing frame 211, a mounting seat 212, a transducer 213, a variable amplitude rod 214 and an ultrasonic pressing head 215. Its working principle is to use the energy generated by ultrasonic vibration to achieve material pressing; the transducer 213 is connected to the fixing frame 211 to convert electrical energy into mechanical vibration energy; when the transducer 213 receives electrical energy input, the transducer 213 will start to vibrate and generate ultrasonic waves. The ultrasonic vibration generated by the transducer 213 is amplified by the variable amplitude rod 214 to generate sufficient energy during the pressing process; the ultrasonic pressing head 215 is set in the mounting seat 212 and is connected to the mounting seat 212 through a connecting strip 217. The transducer 213 and the ultrasonic pressing head 215 are connected by the variable amplitude rod 214. Therefore, when the transducer 213 vibrates, the ultrasonic pressing head 215 will also vibrate.

[0032] Heat dissipation channels 216 are set on the left and right sides of the ultrasonic pressing head 215, so that the heat generated by the ultrasonic pressing head 215 can be effectively dissipated during use to prevent it from overheating and affecting its service life or pressing effect. When the ultrasonic pressing head 215 contacts the pressing bottom roller 3 and applies a certain pressure, the ultrasonic vibration energy will be transferred to the pressing bottom roller 3 and the material to be pressed. This energy transfer will cause the molecules inside the material to generate friction and heat, so that the material will melt and bond together, thereby realizing the pressing between the hot air non-woven fabrics.

[0033] As one of the preferred embodiments of the present invention, Figure 1 and Figure 2As shown, the side walls on the left and right sides of the installation box 11 are correspondingly penetrated by a material feeding channel 13, a guide rod 54 is provided inside the material feeding channel 13, and a mounting plate 53 connected to the material feeding channel 13 is provided inside the installation box 11, and a lifting electric cylinder 51 corresponding to the position of the guide rod 54 is provided on the upper surface of the mounting plate 53, and the guide rod 54 can slide through the left and right sides of the material receiving plate 5, and the cylinder end of the lifting electric cylinder 51 is connected to the mounting plate 53, and the telescopic rod end of the lifting electric cylinder 51 is connected to the lower surface of the material receiving plate 5, and a pressing channel 52 is set to penetrate the upper and lower parts of the material receiving plate 5, and the length and width of the pressing channel 52 are the same as those of the arc-shaped working surface 31.

[0034] The material receiving plate 5 is located between the ultrasonic laminating component 21 and the laminating bottom roller 3. Its main function is to support and carry the hot air non-woven fabric and other diaper rolls to be laminated. During the laminating process, the hot air non-woven fabric and other diaper rolls will be placed on the material receiving plate 5 to ensure that they can pass through the laminating area smoothly and accurately. The guide rods 54 set inside the material feeding channel 13 are slidably connected to the left and right sides of the material receiving plate 5. Guided by the guide rods 54, the material receiving plate 5 can move up and down smoothly to adapt to the laminating requirements of materials of different thicknesses. The telescopic rod end of the lifting cylinder 51 is connected to the lower surface of the material receiving plate 5. By controlling the telescopic movement of the lifting cylinder 51, the height of the material receiving plate 5 can be precisely adjusted. This lifting and adjusting function enables the material receiving plate 5 to adapt to materials of different thicknesses and ensures that the materials can be tightly attached to the laminating bottom roller 3 during the laminating process. At the same time, the precise control of the lifting cylinder 51 also improves the automation level and production efficiency of the laminating process.

[0035] As one of the preferred embodiments of the present invention, Figure 1 、 Figure 4 and Figure 5 As shown, one end of the cooling air duct 6 is connected to a plug 61, and the other end of the cooling air duct 6 is an air inlet end. A first main air duct 62 is arranged inside the cooling air duct 6, and several rows of evenly distributed first air outlet holes 63 are arranged on the surface of the cooling air duct 6. The first air outlet holes 63 are evenly arranged along the axial direction of the cooling air duct 6 and are connected to the first main air duct 62.

[0036] The cooling air duct 6 is a tubular structure with a first main air duct 62 inside. One end of the duct is connected to a plug 61 to close the end, and the other end serves as an air inlet end. The air inlet end is connected to an external air source through an air supply pipe. When the external air source enters the first main air duct 62 of the cooling air duct 6 through the air inlet end, the gas will flow along the inside of the pipe. When the gas is ejected from the first air outlet 63, the ultrasonic pressing head 215 will generate a lot of heat during the pressing process, so the outflowing gas can take away the heat, thereby achieving heat dissipation of the ultrasonic pressing head 215.

[0037] As one of the preferred embodiments of the present invention, Figure 1 、 Figure 6 and Figure 7 As shown, the cooling air knife 4 is provided with a fixedly connected connecting plate 41, and the cooling air knife 4 is connected to the lower end of the fixed frame 211 through the connecting plate 41. A second main air duct 43 is provided inside the cooling air knife 4, and a plurality of blowing surfaces 42 are provided on the surface of the cooling air knife 4 facing the ultrasonic pressing head 215. Second blowing holes 44 connected to the second main air duct 43 are correspondingly provided on the surface of the blowing surface 42. The second blowing holes 44 are equidistantly arranged along the length direction of the blowing surface 42, and an end of one end of the cooling air knife 4 is provided with an air inlet pipe 45 connected to the second main air duct 43.

[0038] The air inlet pipe 45 is connected to an external air source via a pipe. When external air enters the second main air channel 43 of the cooling air knife 4 through the air inlet pipe 45, the air flows along the interior of the air channel and is ultimately ejected through the second air holes 44. Because the second air holes 44 are arranged equidistantly along the length of the air blowing surface 42, the air can evenly cover the surface of the ultrasonic pressing head 215, achieving an effective heat dissipation effect. When the cooling gas is ejected from the second air holes 44, it exchanges heat with the surface of the ultrasonic pressing head 215. Since the ultrasonic pressing head 215 generates a large amount of heat during the pressing process, the ejected cooling gas can carry away this heat, thereby reducing the temperature of the pressing head and ensuring its continuous and stable operation.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
