[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1) The support frame provides a stable foundation for the entire lifting and clamping mechanism. The guide shaft, movably inserted into the support frame, acts like a precise track for the lifting seat assembly's lifting movement, effectively preventing deviation or swaying during lifting. The first drive source is dedicated to providing lifting power, driving the lifting seat assembly to move smoothly back and forth vertically along the guide shaft. This allows the mechanism to accurately reach the corresponding height position according to different operational needs. The second drive source, installed on the lifting seat assembly, provides the necessary clamping driving force for the clamping arm assembly. The mirror-shaped and movably inserted clamping arm assemblies on the lifting seat assembly can flexibly move closer or further apart under the drive of the second drive source. This structural design allows the lifting and clamping mechanism to accurately and efficiently complete a series of packaging operations such as gripping, transporting, and placing diapers, greatly improving the working efficiency and quality of the diaper packaging machine.

[0018] 2) The C-shaped arm in the clamping arm assembly is slidably mounted on the lifting seat assembly via a linear guide. The linear guide ensures the smoothness and stability of the C-shaped arm during sliding, enabling the clamping arm assembly to accurately perform the closing and opening actions, thereby improving the clamping accuracy of the diaper. The C-shaped arm is fixedly connected to the output end of the second drive source, ensuring effective power transmission. A detachable clamping plate at one end of the C-shaped arm provides great flexibility. When dealing with diapers of different sizes and specifications, the appropriate clamping plate can be easily and quickly replaced, allowing the mechanism to better adapt to various products. The retractable protective sleeve on one side of the clamping plate plays a crucial protective role. When clamping the diaper, the sleeve cushions the pressure of the clamping plate on the diaper, preventing damage due to direct contact, and also increases the friction between the clamping plate and the diaper, making the clamping effect more secure and reliable.

[0019] 3) The second drive source is a servo motor fixed to the lifting seat assembly. Servo motors are known for their high-precision control performance and fast response speed, enabling precise control of output torque and speed. The belt drive assembly at its output end is fixedly connected to the clamping arm assembly via a pressure plate. Belt drives offer advantages such as smooth transmission and low noise, stably transmitting the power of the servo motor to the clamping arm assembly. This method allows for precise control of the clamping force and operating speed of the clamping arm assembly. Whether the diaper is thin or heavy-duty, appropriate clamping force can be applied according to its actual needs, preventing damage due to excessive clamping force or loss of diaper during handling due to insufficient clamping force, thus ensuring the stability and reliability of the packaging process.

[0020] 4) The lifting seat assembly slides onto the bracket and is connected to the first drive source, allowing the lifting seat to smoothly move up and down along the guide shaft under the drive of the first drive source. The support platform at the top of the lifting seat provides a stable platform for placing diapers. The through-type clamping arm channel formed between the lifting seat and the support platform provides ample space for the movement of the clamping arm assembly, ensuring that the clamping arm assembly is not obstructed during operation and can smoothly complete the clamping and releasing actions. A 2mm thick mirrored protective sleeve on the top of the support platform has multiple benefits. On the one hand, it can effectively protect the diapers from being scratched by the rough parts of the support platform surface during placement and transportation; on the other hand, the mirrored protective sleeve can reduce the friction between the diapers and the support platform, making it easier and more convenient for the clamping arm assembly to grasp the diapers, improving operational efficiency.

[0021] 5) The second servo motor of the first drive source is rotatably mounted on one side of the bracket. Its output end is connected to the second belt drive assembly, which is driven by the second pressure plate to the lifting seat. The second servo motor can precisely control the speed and torque, providing stable power for the lifting seat assembly to rise and fall. The belt drive assembly has the advantages of smooth transmission, high transmission efficiency, and simple structure. It can efficiently transmit the power of the second servo motor to the lifting seat, enabling the lifting seat assembly to achieve rapid and accurate lifting movements, thus improving the efficiency of the entire packaging process.

[0022] 6) A detachable baffle plate on one side of the support frame, with a height significantly greater than that of the clamping arm assembly, greatly enhances the safety of the mechanism during operation. When the lifting and clamping mechanism is handling diapers, diapers may accidentally slip. The baffle plate acts as a sturdy barrier, effectively preventing falling diapers from scattering, thus preventing material waste and reducing the risk of equipment malfunction or personal injury due to falling materials. Furthermore, the detachable baffle plate is highly practical; it can be easily removed for maintenance, cleaning, or layout adjustments based on different packaging scenarios, offering high flexibility. The self-tensioning component on one side of the support frame, and the structure where one end of the second belt drive assembly can be rotatably inserted into the self-tensioning component, play a crucial role in the stable operation of the entire lifting and clamping mechanism. During long-term operation, the belt drive assembly may loosen due to wear, temperature changes, etc. The self-tensioning component can monitor and automatically adjust the tension of the second belt drive assembly in real time. When the drive belt becomes slightly slack, the self-tensioning component automatically applies a suitable force to restore the drive belt to its optimal tension. This not only ensures that the second belt drive assembly can stably transmit power from the second servo motor to the lifting seat, maintaining smooth lifting and lowering movements, but also extends the lifespan of the drive belt, reduces slippage and tooth skipping caused by belt slack, lowers equipment maintenance costs and downtime, and improves production efficiency.

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.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Please see the appendix Figs. 1-2 As shown: A lifting clamping mechanism mainly consists of a support 1, a first drive source 2, a lifting seat assembly 3, a second drive source 4, and a clamping arm assembly 5. The support 1 provides a stable support structure for the entire mechanism; the first drive source 2 is mounted on the support 1 and is responsible for providing lifting power, enabling the lifting seat assembly 3 to move vertically; the lifting seat assembly 3 is movably inserted into the support 1, with one end fixedly connected to the guide shaft 11, and achieves lifting movement under the drive of the first drive source 2; the second drive source 4 is mounted on the lifting seat assembly 3 and provides clamping driving force for the clamping arm assembly 5; the clamping arm assembly 5 is mirror-image and movably inserted into the lifting seat assembly 3, and under the drive of the second drive source 4, adjacent clamping arm assemblies 5 can move closer or further apart to achieve clamping and releasing actions on the diaper.

[0029] Based on the above embodiments, the support frame 1, as the basic support structure, is made of high-strength metal material to ensure stable support of other components throughout the packaging process. A guide shaft 11 is movably inserted into the support frame 1 to provide precise guidance for the lifting movement of the lifting seat assembly 3, ensuring its smoothness and accuracy. A baffle plate 11 is detachably provided on one side of the support frame 1. The height of the baffle plate 11 is much greater than the height of the clamping arm assembly 5, effectively preventing the diaper from falling during handling and providing protection. A self-tensioning assembly 12 is also provided on one side of the support frame 1. One end of the second belt drive assembly 22 is rotatably inserted into the self-tensioning assembly 12 to automatically adjust the tension of the second belt drive assembly 22, ensuring the stability and reliability of the transmission.

[0030] Based on the above embodiments, the first drive source 2 includes a second servo motor 21 rotatably mounted on one side of the support 1. The second servo motor 21 features high control precision and fast response speed. The output end of the second servo motor 21 is connected to a second belt drive assembly 22, which is connected to the lifting seat 31 via a second pressure plate. Belt drives offer advantages such as smooth transmission, low noise, and simple structure. By driving the second belt drive assembly 22 with the second servo motor 21, the lifting speed and position of the lifting seat assembly 3 can be precisely controlled, enabling the gripping and placement of diapers at different heights.

[0031] Based on the above embodiments, the lifting seat assembly 3 includes a lifting seat 31 slidably inserted into the bracket 1. The lifting seat 31 is connected to the second belt drive assembly 22 of the first drive source 2 via a second pressure plate and moves up and down along the guide shaft 11 under the drive of the first drive source 2. The top of the lifting seat 31 is provided with a support platform 32 for placing the diaper to be grasped. The lifting seat 31 and the support platform 32 form a through-hole clamping arm channel, providing space for the movement of the clamping arm assembly 5. The top of the support platform 32 is provided with a 2mm thick mirror-finished protective sleeve, which can protect the diaper from damage and reduce the friction between the diaper and the support platform, making it easier for the clamping arm assembly 5 to grasp the diaper.

[0032] Based on the above embodiments, the second drive source 4 includes a servo motor 41 fixed on the lifting seat assembly 3, which provides stable and precise power output. The output end of the servo motor 41 is equipped with a belt drive assembly 42, which is fixedly connected to the clamping arm assembly 5 via a pressure plate. By controlling the forward and reverse rotation and speed of the servo motor 41, the belt drive assembly 42 is driven, thereby enabling the clamping arm assemblies 5 to move closer or further apart, precisely controlling the clamping force to meet the clamping requirements of different diaper sizes.

[0033] Based on the above embodiments, the clamping arm assembly 5 includes a C-shaped arm 51 slidably mounted on the lifting seat assembly 3 via a linear guide. The C-shaped arm 51 is fixedly connected to the belt drive assembly 42 of the second drive source 4 via a pressure plate, ensuring stable opening and closing under the drive of the second drive source 4. A clamping plate 52 is detachably mounted on one end of the C-shaped arm 51, facilitating the replacement of appropriate clamping plates according to different sizes of diapers. A retractable protective sleeve 53 is provided on one side of the clamping plate 52. When clamping the diaper, the protective sleeve 53 acts as a buffer to prevent damage to the diaper from the clamping plate, while increasing the friction between the clamping plate and the diaper, making the clamping more secure.

[0034] The working principle of this utility model is as follows: When the diaper is conveyed onto the support platform 32, the second servo motor 21 of the first drive source 2 starts, driving the second belt drive assembly 22 to lower the lifting seat assembly 3 along the guide shaft 11 to a suitable height, ensuring that the clamping arm assembly 5 can reach the diaper gripping position. The servo motor 41 of the second drive source 4 starts, driving the belt drive assembly 42 to make the mirror-set clamping arm assemblies 5 approach each other along the guide rail via the C-shaped arm 51. As the C-shaped arm 51 moves, the clamping plate 52 gradually approaches the diaper, and the retractable sheath 53 contacts and clamps the diaper. Due to the buffering and increased friction of the sheath 53, the diaper can be gripped stably. After gripping the diaper, the second servo motor 21 of the first drive source 2 starts again, driving the second belt drive assembly 22 to move in the opposite direction, causing the lifting seat assembly 3, along with the clamping arm assembly 5 and the gripped diaper, to rise to a suitable height. Then, the entire lifting and clamping mechanism translates or rotates according to the action requirements of the packaging machine. This translation or rotation is controlled by other mechanisms of the packaging machine (not described in detail in this invention). The diaper is then transported to the packaging station. Upon arrival at the packaging station, the servo motor 41 of the second drive source 4 reverses, driving the belt drive assembly 42 to move the clamping arm assemblies 5 apart, and the clamping plate 52 releases the diaper, placing it on the packaging station. Afterwards, the first drive source 2 drives the lifting seat assembly 3 to descend to its initial position, ready for the next gripping operation. In summary, the lifting and clamping mechanism of this utility model for diaper packaging machines can operate efficiently and stably, providing reliable gripping and transporting functions for diaper packaging machines, improving the automation level and production efficiency of diaper packaging, and has good market application prospects.
