Technical Field

[0001] This invention relates to the field of disposable hygiene product manufacturing equipment, and more particularly to a low-cost cold-press welding mechanism. Background Technology

[0002] In the production of pull-up diapers, the welding processes for the waistband typically include: adhesive bonding, heat sealing welding, and ultrasonic welding. Each of these processes has its own advantages and disadvantages. For example, adhesive bonding results in cost waste, and excessive glue can reduce breathability and cause skin allergies; heat sealing welding is slow, has limited material options, and produces a rough feel and poor comfort; while ultrasonic welding is expensive, requires specific operating procedures, and is prone to damage. Summary of the Invention

[0003] Therefore, in view of the above problems, the present invention provides a low-cost cold-press welding mechanism with low welding cost, high welding efficiency and wide applicability to a wide range of materials.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A low-cost cold-press welding mechanism includes a frame, a control system, a first drive motor, a rotating shaft, a cam, a slide rod, at least one first guide assembly, two side plates, at least one mounting base, a gas distribution assembly, and at least one welding and cutting assembly. The rotating shaft is rotatably mounted on the frame, and its axial direction is defined as extending laterally. The first drive motor is connected to the rotating shaft. The cam is sleeved on the rotating shaft and rotates relative to it. A groove is provided on the circumferential surface of the cam. One end of the slide rod is embedded in the groove and slides along it. The two side plates are located on the lateral sides of the cam and are fixedly connected to the rotating shaft. Each mounting base is circumferentially mounted on the outer circumferential surface of the side plate. Each first guide assembly is located on the mounting base and is distributed laterally. Each welding and cutting assembly is located on the first guide assembly and connected to the slide rod. The gas distribution assembly is located on one lateral side of the rotating shaft. The welding and cutting assembly includes a second drive motor, a transmission assembly, a support base, an extrusion plate, a swing arm, a drive cylinder, a welding roller, and a cutting roller. The support base is mounted on a first guide assembly. The extrusion plate is located on one lateral side of the support base and has negative pressure adsorption holes connected to a gas distribution assembly. The middle lateral part of the swing arm is hinged to the support base. The welding roller and the cutting roller are rotatably mounted on one lateral end of the swing arm for cooperation with the extrusion plate. The second drive motor is mounted on the swing arm and is connected to the welding roller and the cutting roller respectively through the transmission assembly. The circumferential surface of the welding roller has several rectangularly distributed welding teeth. The two ends of the drive cylinder are hinged to the other lateral end of the support base and the other lateral end of the swing arm, respectively. The control system is electrically connected to the first drive motor, the second drive motor, the drive cylinder, and the air distribution assembly, respectively.

[0005] Furthermore, it also includes at least one mounting plate and a second guide assembly. Each mounting plate is arranged around the outer peripheral surface of the side plate and located below the mounting base. The second guide assembly is disposed on the mounting plate and is distributed in the lateral direction. The slide rod is connected to the second guide assembly to improve the sliding stability of the slide rod.

[0006] Furthermore, an adjustment assembly is provided between the mounting base and the side plate. The adjustment assembly includes a planar cam, a follower, and a third guide assembly. The third guide assembly is located on the outer side of the side plate and is distributed along the radial direction of the rotating shaft. The mounting base is located on the third guide assembly. The planar cam is sleeved on the rotating shaft. The follower connects the planar cam and the mounting base.

[0007] Furthermore, the rotational speed of the welding roller is at least 8 m / s.

[0008] Furthermore, the downward pressure of the welding roller is at least 6000N.

[0009] Furthermore, the tooth depth of the welding teeth on the welding roller is <2mm.

[0010] Furthermore, the tooth profile area of ​​the welding teeth of the welding roller is >1mm. 2 .

[0011] Furthermore, the control system includes a controller, a first encoder connected to the rotating shaft for detecting the rotational speed of the rotating shaft, a second encoder connected to the welding roller for detecting the rotational speed of the welding roller, a third encoder connected to the cutting roller for detecting the rotational speed of the cutting roller, a position sensor for detecting the moving distance of the mounting base, a pressure sensor for detecting the downward pressure of the welding roller, and a touch screen display. The first encoder, second encoder, third encoder, position sensor, and pressure sensor are electrically connected to the controller.

[0012] Furthermore, the control method of the control system includes the following steps: 1) Operators input the specifications and model of the product being produced via the touch screen, and the controller calls up and displays the corresponding preset parameters, including welding speed, cutting phase, welding pressure, and target position of the mounting base; 2) The controller starts the first drive motor, which drives the rotating shaft to rotate. The rotating shaft drives the cam to rotate. The cam drives the welding and cutting assembly to reciprocate along the first guide assembly through the slide bar. The controller starts the drive cylinder, which applies pressure to the welding roller through the swing arm. The pressure sensor detects the actual downward pressure in real time and feeds the signal back to the controller. The controller compares the actual pressure with the preset value and adjusts the output force of the drive cylinder to ensure the stability and accuracy of the welding pressure. 3) The controller starts the second drive motor, which drives the welding roller and the cutting roller to rotate through the transmission component. The second encoder and the third encoder monitor the rotation speed of the welding roller and the cutting roller in real time and feed the signal back to the controller. The controller adjusts the rotation speed of the second drive motor according to the feedback value to ensure that the rotation speed of the welding roller reaches and stabilizes at the set value. 4) When it is necessary to change the product specifications, the controller drives the plane cam to rotate. The plane cam drives the mounting seat to move radially along the side plate through the follower and the third guide assembly. The position sensor detects the moving distance of the mounting seat in real time and feeds the signal back to the controller until the mounting seat reaches the target position, thereby accurately adjusting the outer diameter of the mechanism to adapt to different product specifications. 5) While the welding roller and the extrusion plate are working together to perform high-speed, high-pressure cold welding on the waistband material, the cutting roller driven by the second drive motor works synchronously to precisely cut the continuous waistband material. The controller ensures the synchronization of welding and cutting actions through encoder signals to ensure the consistency of product dimensions. 6) Throughout the entire operation, the controller continuously receives signals from various sensors to monitor the equipment's operating status in real time. If parameters such as speed, pressure, or position are detected to exceed the set range, the controller will immediately issue an alarm and automatically execute protective actions such as shutdown to ensure production safety and product quality.

[0013] By adopting the aforementioned technical solution, the beneficial effects of this invention are as follows: This low-cost cold-press welding mechanism, by employing a cold-press welding process, eliminates the need for heating or the use of adhesives, effectively avoiding the problem of rough product feel caused by heat sealing welding and the increased costs and skin allergy risks that may be caused by adhesive bonding, making the welded product feel softer and more comfortable. Moreover, the cold-press welding mechanism integrates welding and cutting functions. The second drive motor drives the welding roller and the cutting roller simultaneously through the transmission component, allowing cutting to be performed while the material is being welded, reducing independent cutting processes, simplifying the production process, and lowering equipment costs. Specifically, the first drive motor drives the rotating shaft to rotate, which in turn drives the welding and cutting component to rotate. The welding and cutting component is driven to reciprocate along the first guide component through the cam and slide rod. The drive cylinder applies pressure to the welding roller through the swing arm, while the second drive motor drives the welding roller and the cutting roller to rotate through the transmission component, so that the welding roller cooperates with the extrusion plate to achieve extrusion welding, and the cutting roller cuts the waistband material, improving production efficiency.

Detailed Implementation

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0016] The embodiments of the present invention are as follows: refer to Figures 1 to 4 As shown, a low-cost cold-press welding mechanism includes a frame, a control system 1, a first drive motor 2, a rotating shaft 3, a cam 4, a slide rod 5, two first guide assemblies 6, two side plates 7, two mounting bases 8, a gas distribution assembly 9, and two welding and cutting assemblies 10. The rotating shaft 3 is rotatably mounted on the frame, and its axial direction is defined as its transverse direction. The first drive motor 2 is connected to the rotating shaft 3. The cam 4 is sleeved on the rotating shaft 3 and rotates relative to the rotating shaft 3. The circumference of the cam 4... The surface is provided with a sliding groove 41, one end of the sliding rod 5 is embedded in the sliding groove 41 and slides along the sliding groove 41, the two side plates 7 are provided on the lateral sides of the cam 4 and are fixedly connected to the rotating shaft 3, each mounting seat 8 is arranged around the outer circumferential surface of the side plate 7, each first guide component 6 is respectively provided on the mounting seat 8, the first guide components 6 are distributed in the lateral direction, each welding and cutting component 10 is respectively provided on the first guide component 6 and connected to the sliding rod 5, and the air distribution component 9 is provided on one lateral side of the rotating shaft 3; The welding and cutting assembly 10 includes a second drive motor 101, a transmission assembly 102, a support base 103, an extrusion plate 104, a swing arm 105, a drive cylinder 106, a welding roller 107, and a cutting roller 108. The support base 103 is mounted on the first guide assembly 6. The extrusion plate 104 is located on one lateral side of the support base 103. The extrusion plate 104 has negative pressure adsorption holes (not shown in the figure) connected to the gas distribution assembly 9. The middle lateral part of the swing arm 105 is hinged to the support base 103. The welding roller 107 and the cutting roller 108 are rotatably mounted on one lateral end of the swing arm 105 for cooperation with the extrusion plate 104. The second drive motor 101 is mounted on the swing arm 105 and is connected to the welding roller 107 and the cutting roller 108 respectively through the transmission assembly 102. The welding roller 107 has a plurality of rectangularly distributed welding teeth 109 on its circumferential surface. The two ends of the drive cylinder 106 are respectively hinged to the other lateral end of the support base 103 and the other lateral end of the swing arm 105. The control system 1 is electrically connected to the first drive motor 2, the second drive motor 101, the drive cylinder 106, and the air distribution assembly 9, respectively.

[0017] This low-cost cold-press welding mechanism, by employing a cold-press welding process, eliminates the need for heating or the use of adhesives, effectively avoiding the rough texture of products caused by heat sealing welding and the increased costs and skin allergy risks associated with adhesive bonding. This results in a softer and more comfortable feel after welding. Furthermore, the cold-press welding mechanism integrates welding and cutting functions. A second drive motor 101, via a transmission assembly 102, simultaneously drives the welding roller 107 and the cutting roller 108. Cutting can be performed simultaneously with material welding, reducing independent cutting steps, simplifying the production process, and lowering equipment costs. Specifically, the first drive motor 2 drives the rotating shaft 3 to rotate, which in turn drives the welding and cutting assembly 10 to rotate. The cam 4 and slide bar 5 drive the welding and cutting assembly 10 to reciprocate along the first guide assembly 6. The drive cylinder 106 applies pressure to the welding roller 107 via the swing arm 105. Simultaneously, the second drive motor 101, via the transmission assembly 102, drives the welding roller 107 and the cutting roller 108 to rotate, allowing the welding roller 107 to cooperate with the extrusion plate 104 to achieve extrusion welding, while the cutting roller cuts the waistband material, improving production efficiency.

[0018] Furthermore, it also includes two mounting plates 21 and a second guide assembly 22. Each mounting plate 21 is arranged around the outer peripheral surface of the side plate 7 and located on the lower side of the mounting base 8. The second guide assembly 22 is disposed on the mounting plate 21 and is distributed in the transverse direction. The slide rod 5 is connected to the second guide assembly 22 to improve the sliding stability of the slide rod 5. By setting the second guide assembly 22 on the mounting plate 21 and connecting it to the slide rod 5, additional support and guidance are provided for the sliding of the slide rod 5, which effectively improves the stability of the slide rod 5 when sliding in the slide groove 41, thereby ensuring the smoothness of the movement of the welding and cutting assembly 10 and helping to improve the accuracy and quality of welding and cutting.

[0019] Furthermore, an adjustment assembly 20 is provided between the mounting base 8 and the side plate 7. The adjustment assembly 20 includes a planar cam 201, a follower 202, and a third guide assembly 203. The third guide assembly 203 is located on the outer side of the side plate 7 and is distributed along the radial direction of the rotating shaft 3. The mounting base 8 is located on the third guide assembly 203. The planar cam 201 is sleeved on the rotating shaft 3. The follower 202 connects the planar cam 201 and the mounting base 8. By providing the adjustment assembly 20, which consists of the planar cam 201, the follower 202, and the third guide assembly 203, between the mounting base 8 and the side plate 7, the mounting base 8 can be driven to move radially along the side plate 7 when the planar cam 201 rotates. This allows for precise adjustment of the position of the welding and cutting assembly 10, enabling the mechanism to adapt more flexibly and accurately to products of different sizes and specifications, further improving the versatility and production efficiency of the equipment.

[0020] Specifically, the rotational speed of the welding roller 107 is at least 8 m / s, preferably 9.5 m / s, which can achieve extremely high welding efficiency while ensuring welding quality, far exceeding the traditional heat sealing welding process, and meeting the needs of high-speed production lines.

[0021] Specifically, the downward pressure of the welding roller 107 is at least 6000N, preferably 6100N, which, in conjunction with the extrusion plate 104, provides sufficient pressure for cold pressing welding, enabling the materials to achieve a firm composite under the combined action of high speed and high pressure, thus ensuring the strength and reliability of the weld.

[0022] Specifically, the depth of the welding teeth 109 of the welding roller 107 is less than 2mm, preferably 3mm, which can avoid excessive damage to the material structure due to excessive tooth depth, thereby maintaining the softness and comfort of the material while ensuring the welding effect.

[0023] Specifically, the welding teeth 109 of the welding roller 107 have a tooth area >1mm2, preferably 1.5mm2, which can ensure that the welding point has sufficient contact area, thereby forming a stable and firm welding effect and preventing the weld from cracking or falling off.

[0024] In this embodiment, the control system 1 includes a controller 11, a first encoder 12 connected to the rotating shaft 3 for detecting the rotational speed of the rotating shaft 3, a second encoder 13 connected to the welding roller 107 for detecting the rotational speed of the welding roller 107, a third encoder 14 connected to the cutting roller 108 for detecting the rotational speed of the cutting roller 108, a position sensor 15 for detecting the moving distance of the mounting base 8, a pressure sensor 16 for detecting the downward pressure of the welding roller 107, and a touch screen 17. The first encoder 12, second encoder 13, third encoder 14, position sensor 15, and pressure sensor 16 are electrically connected to the controller 11. By integrating multiple sensors and connecting them to the controller, real-time and accurate monitoring and control of the rotational speed of the rotating shaft 3, welding roller 107, and cutting roller 108, the moving distance of the mounting base 8, and the welding downward pressure are achieved. Operators can set parameters and monitor status through the touch screen 17, making the entire welding process highly automated and intelligent, ensuring the stability of product quality, and facilitating operation and maintenance.

[0025] Furthermore, the control method of the control system 1 includes the following steps: 1) The operator inputs the specifications and model of the product being produced through the touch screen 17, and the controller 11 calls up and displays the corresponding preset parameters, including welding speed, cutting phase, welding pressure, and target position of mounting base 8; 2) The controller 11 starts the first drive motor 2, which drives the rotating shaft 3 to rotate. The rotating shaft 3 drives the side plate 7 and the mounting base 8 to rotate, and drives the welding and cutting assembly 10 to reciprocate along the first guide assembly 6 through the cam 4 and the slide rod 5. The controller 11 starts the drive cylinder 106, which applies pressure to the welding roller through the swing arm 105. The pressure sensor 16 detects the actual downward pressure in real time and feeds the signal back to the controller 11. The controller 11 compares the actual pressure with the preset value and adjusts the output force of the drive cylinder 106 to ensure the stability and accuracy of the welding pressure. 3) The controller 11 starts the second drive motor 101, which drives the welding roller 107 and the cutting roller 108 to rotate through the transmission component 102. The second encoder 13 and the third encoder 14 monitor the rotation speed of the welding roller 107 and the cutting roller 108 in real time and feed the signal back to the controller 11. The controller 11 adjusts the rotation speed of the second drive motor 101 according to the feedback value to ensure that the rotation speed of the welding roller 107 reaches and stabilizes at the set value. 4) When it is necessary to change the product specifications, the controller 11 drives the plane cam 201 to rotate. The plane cam 201 drives the mounting seat 8 to move radially along the side plate 7 through the follower 202 and the third guide assembly 203. The position sensor 15 detects the moving distance of the mounting seat 8 in real time and feeds the signal back to the controller 11 until the mounting seat 8 reaches the target position, thereby accurately adjusting the outer diameter of the mechanism 20 to adapt to different product specifications. 5) While the welding roller 107 and the extrusion plate 104 are working together to perform high-speed, high-pressure cold welding on the waistband material, the cutting roller driven by the second drive motor 101 works synchronously to precisely cut the continuous waistband material. The controller 11 ensures the synchronization of welding and cutting actions through encoder signals to ensure the consistency of product dimensions. 6) Throughout the entire operation, the controller 11 continuously receives signals from various sensors to monitor the operating status of the equipment in real time. If parameters such as speed, pressure, or position are detected to exceed the set range, the controller will immediately issue an alarm and can automatically perform protective actions such as shutdown to ensure production safety and product quality.
