DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the utility model specification. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0036] Embodiment 1

[0037] As a preferred embodiment of the utility model, with reference to the drawings in the specification Figure 1 , the drawings in the specification Figure 2 and the drawings in the specification Figure 3As shown, the embodiment discloses a phase resetting mechanism, which is specially designed to solve a series of problems caused by inaccurate phase during the process of sanitary napkin sorting. The overall structure includes three main parts: feeding conveying assembly 1, equidistant synchronous belt conveying assembly 2 and discharging conveying assembly 3.

[0038] Firstly, the equidistant synchronous belt conveying assembly 2 is the core part of the mechanism, which contains synchronous belt I 4 and synchronous belt II 5. Synchronous belt I 4 and synchronous belt II 5 are arranged side by side with a set distance, which is determined based on the size, thickness and required operation space of the sanitary napkin, etc. to ensure that the sanitary napkin can be provided with a suitable conveying channel. A negative pressure chamber 6 is arranged between synchronous belt I 4 and synchronous belt II 5, which plays a crucial role in the mechanism. The negative pressure chamber 6 can generate stable and uniform negative pressure adsorption force through special design and connection, to ensure the position accuracy of the sanitary napkin during conveying.

[0039] Further, a plurality of pushing blocks 7 are arranged on synchronous belt I 4 and synchronous belt II 5, which are uniformly distributed on the two synchronous belts, and the pushing blocks 7 on synchronous belt I 4 correspond to the pushing blocks 7 on synchronous belt II 5. The number and spacing of the pushing blocks 7 are accurately set according to the size of the sanitary napkin and the required equidistant conveying requirement, which can exert uniform pushing force on the sanitary napkin during the operation of the synchronous belt, to ensure that the sanitary napkin advances at the predetermined interval and speed during conveying, avoiding the inconsistent interval between the front and rear sanitary napkins or the accumulation and extrusion of the sanitary napkin during conveying.

[0040] The end of the feeding conveying assembly 1 extends to between synchronous belt I 4 and synchronous belt II 5 and is connected with the negative pressure chamber 6, which is designed ingeniously to ensure that the sanitary napkin can smoothly enter the equidistant synchronous belt conveying assembly 2 from the feeding conveying assembly 1 and be effectively adsorbed by the negative pressure adsorption force of the negative pressure chamber 6. The feeding conveying assembly 1 plays a role of "pre-protection" in the whole conveying process of the sanitary napkin, which is responsible for orderly conveying the sanitary napkin from the upstream process, and its speed and stability are crucial for the subsequent operation.

[0041] The head of the discharging conveying assembly 3 extends to between synchronous belt I 4 and synchronous belt II 5 and is connected with the negative pressure chamber 6, which will smoothly convey the sanitary napkin to the next production link after the sanitary napkin is processed by the equidistant synchronous belt conveying assembly 2 and the phase is reset. The design of the discharging conveying assembly 3 fully considers the connection with the equidistant synchronous belt conveying assembly 2, to ensure that the sanitary napkin will not be disturbed in position and posture when receiving the sanitary napkin after phase resetting, and to ensure the stability and accuracy of the sanitary napkin during output.

[0042] In the embodiment, the components of the whole resetting phase mechanism cooperate with each other to form an organic whole, from the feeding, through the accurate processing of the equidistant synchronous belt conveying component 2, to the discharging, forming a complete, efficient and stable conveying and phase resetting system, which provides a reliable precondition for the subsequent sanitary napkin sheeting work, greatly improves the sheeting accuracy and efficiency, reduces the defective rate, and improves the quality and efficiency of the whole sanitary napkin production process.

[0043] Embodiment 2

[0044] As another preferable embodiment of the utility model, the embodiment is a further detailed supplement and elaboration of the technical solution of the utility model on the basis of the above-mentioned embodiment 1.

[0045] In the embodiment, referring to the drawings in the specification Figure 2 As shown in the drawings, the feeding conveying component 1 comprises an upper feeding clamping belt 19 and a lower feeding clamping belt 20, which are oppositely arranged to clamp and convey the material. This opposite arrangement has important advantages. The distance between the upper feeding clamping belt 19 and the lower feeding clamping belt 20 can be accurately adjusted according to the thickness of the sanitary napkin being processed, so as to ensure that sufficient clamping force can be provided to the sanitary napkin during feeding to avoid sliding, deviation or turning of the sanitary napkin during conveying. In actual operation, the upper feeding clamping belt 19 and the lower feeding clamping belt 20 work cooperatively, just like two hands firmly holding the sanitary napkin, so that it moves stably along the predetermined conveying path. Moreover, this clamping method not only ensures the stability of material conveying, but also can flexibly adjust the clamping force according to different production speeds and characteristics of the sanitary napkin, so as to ensure that different specifications and types of sanitary napkins can enter the subsequent equidistant synchronous belt conveying component 2 in the best state.

[0046] In addition, the outfeed conveying assembly 3 comprises an upper outfeed clamping belt 21 and a lower outfeed clamping belt 22, which are oppositely arranged and used for clamping and conveying the material. The upper outfeed clamping belt 21 and the lower outfeed clamping belt 22 are also crucial. They play an important role when the sanitary napkin is completed with the phase resetting and is output from the equidistant synchronous belt conveying assembly 2. When the sanitary napkin is pushed by the pushing block 7 and passes through the negative pressure chamber 6 between the synchronous belt I 4 and the synchronous belt II 5, the upper outfeed clamping belt 21 and the lower outfeed clamping belt 22 will play their unique functions. They will clamp the sanitary napkin with a proper clamping force according to the shape and size of the sanitary napkin, and then "pick up" the sanitary napkin from the area of the negative pressure chamber 6 and the synchronous belt, and then safely and stably send the sanitary napkin to the subsequent production process. In the working process, they can effectively prevent the position change of the sanitary napkin caused by its inertia or external factors (such as slight vibration) when the sanitary napkin is outfed, so as to ensure that the sanitary napkin still maintains an ideal posture and phase when it leaves the phase resetting mechanism, and prepares for the subsequent sheeting operation.

[0047] It is worth mentioning that the upper infeed clamping belt 19, the lower infeed clamping belt 20, the upper outfeed clamping belt 21 and the lower outfeed clamping belt 22 all adopt high-quality wear-resistant materials. The materials have good flexibility and friction, which can not only ensure the effective clamping of the sanitary napkin, but also prolong the service life of the components and reduce the maintenance cost of the equipment. At the same time, the running speed of these belts can be accurately adjusted according to the speed requirement of the entire production process, so as to ensure the cooperation with other components and prevent the problems such as material blockage or disconnection caused by speed mismatch.

[0048] Through the detailed supplement of the infeed conveying assembly 1 and the outfeed conveying assembly 3 in the embodiment, the functions of the entire phase resetting mechanism are further improved, so that the entire process from the input of the material to the phase resetting and then to the output is more smooth, stable and efficient, which provides a more powerful guarantee for the accuracy and efficiency of the sheeting of the sanitary napkin.

[0049] Embodiment 3

[0050] As another preferable embodiment of the utility model, the embodiment is a further detailed supplement and elaboration of the technical scheme of the utility model on the basis of the above-mentioned embodiment 1 or embodiment 2.

[0051] Firstly, refer to the drawings in the specification Figure 1As shown, as an embodiment of the present embodiment, the equal-interval synchronous belt conveying assembly 2 is provided with limiting plates 8 on both sides. The limiting plates 8 play an indispensable role in the entire phase resetting mechanism. They are accurately positioned on both sides of the equal-interval synchronous belt conveying assembly 2, and strictly limit the conveying process of the sanitary napkin on the synchronous belt I 4 and the synchronous belt II 5. The distance between the limiting plates 8 and the synchronous belt I 4 and the synchronous belt II 5 is carefully designed, which is neither too wide to effectively limit the position of the sanitary napkin and prevent it from sliding or deviating from the predetermined track, nor too narrow to hinder the normal conveying of the sanitary napkin. In this way, even in the case of high-speed conveying, it can ensure that the sanitary napkin always advances along the set path, providing a stable and reliable position guarantee for the subsequent phase resetting operation. At the same time, the material selection of the limiting plates 8 is also very important. A material with certain hardness and wear resistance is selected to ensure that it will not wear or deform due to frequent friction of the sanitary napkin during long-term use, ensuring the long-term stable operation of the entire mechanism.

[0052] Secondly, as an example of the present embodiment, the equal-interval synchronous belt conveying assembly 2 also includes a driving synchronous pulley set and a driven synchronous pulley set. The driving synchronous pulley set includes a driving shaft 9, a main synchronous pulley I 10 and a main synchronous pulley II 11, both of which are assembled on the driving shaft 9 through tension bearings; the driven synchronous pulley set includes a driven shaft 12, a driven synchronous pulley I 13 and a driven synchronous pulley II 14, both of which are assembled on the driven shaft 12 through tension bearings; the synchronous belt I 4 is sleeved on the main synchronous pulley I 10 and the driven synchronous pulley I 13, and the synchronous belt II 5 is sleeved on the main synchronous pulley II 11 and the driven synchronous pulley II 14. The application of tension bearings is of great significance here, which can ensure that the main synchronous pulley I 10, the main synchronous pulley II 11, the driven synchronous pulley I 13 and the driven synchronous pulley II 14 are assembled on the driving shaft 9 and the driven shaft 12 firmly and with certain adjustability. By adjusting the tension bearing, the tension of the synchronous belt can be accurately controlled, so that the synchronous belt and the synchronous pulley maintain appropriate friction, ensuring the stable operation of the synchronous belt, avoiding the phenomenon of slipping due to too loose synchronous belt, affecting the conveying speed and interval accuracy of the material, or causing additional wear and loss of the synchronous belt and the synchronous pulley due to too tight synchronous belt. In addition, the cooperative work of the driving synchronous pulley set and the driven synchronous pulley set provides a stable power transmission system for the entire equal-interval synchronous belt conveying assembly 2, so that the synchronous belt I 4 and the synchronous belt II 5 can run at a uniform and stable speed, thereby pushing the sanitary napkin to convey at equal intervals and reset the phase. The design of the driving shaft 9 and the driven shaft 12 also fully considers the carrying capacity and rotational stability, and is made of high-strength material to ensure that there is no bending or deformation during high-speed operation, ensuring smooth and reliable power transmission of the entire mechanism.

[0053] Further, as another embodiment of the present embodiment, referring to the drawings attached to the specification Figure 2 and the drawings attached to the specification Figure 3 As shown in the drawings attached to the specification, the negative pressure chamber 6 comprises a negative pressure chamber shell 16, a plurality of negative pressure suction holes 15 are arranged on the upper end of the negative pressure chamber shell 16, and the bottom of the negative pressure chamber shell 16 is connected with a negative pressure source through a gas suction joint 18. The design of the negative pressure chamber shell 16 not only needs to consider its structural strength to withstand a certain pressure, but also needs to consider its cooperation with the synchronous belt I 4 and the synchronous belt II 5 to ensure that it can be closely attached and does not affect the conveying of the sanitary napkin. The negative pressure suction holes 15 are uniformly distributed on the upper end of the negative pressure chamber shell 16, and the number and aperture of the negative pressure suction holes 15 are accurately calculated and tested according to the size and weight of the sanitary napkin and the required suction force, so as to ensure that the sanitary napkin can be firmly adsorbed at the predetermined position under different production speeds, and the stability during the phase resetting process is ensured. The bottom of the negative pressure chamber shell 16 is connected with the negative pressure source through the gas suction joint 18, and this connection mode is convenient for flexibly adjusting the negative pressure according to the actual demand, so that the whole negative pressure system can realize accurate negative pressure control according to sanitary napkins of different specifications and production process requirements.

[0054] More importantly, a pressure sensor 17 for detecting the pressure condition of the negative pressure chamber 6 is arranged on one side of the negative pressure chamber 6. The pressure sensor 17 can monitor the pressure of the negative pressure chamber 6 in real time, and can feed back to the control system in time when the pressure is abnormal. For example, if the pressure is too low, the sanitary napkin may not be adsorbed firmly, which affects the stability of the phase resetting; if the pressure is too high, the sanitary napkin may be damaged or the energy consumption may be increased. Through the monitoring of the pressure sensor 17, the operator can quickly adjust the working state of the negative pressure source according to the feedback information, so as to ensure that the pressure of the negative pressure chamber 6 is always in the best state, and intelligent and accurate protection is provided for the stable conveying and phase resetting of the sanitary napkin, and the reliability and stability of the whole phase resetting mechanism are further improved.

[0055] The present embodiment further perfects the technical scheme of the phase resetting mechanism and improves the accuracy, stability and reliability of the mechanism in actual application through further detailed description and optimization of the limiting plate 8, the driving synchronous pulley set, the driven synchronous pulley set and the negative pressure chamber 6, thereby providing more comprehensive technical support for realizing efficient and high-quality sanitary napkin sheeting operation.

[0056] Embodiment 4

[0057] As another preferable embodiment of the present utility model, the present embodiment is a further detailed supplement and elaboration of the technical scheme of the present utility model on the basis of the above-mentioned embodiment 1, embodiment 2 or embodiment 3. It aims to further optimize the overall performance and stability of the phase resetting mechanism.

[0058] In the embodiment, refer to the attached drawings of the specification Figure 1 The reset phase mechanism further comprises a bottom plate 23, which can be regarded as the "cornerstone" of the entire mechanism, providing a stable mounting base and support structure for other components. The equidistant synchronous belt conveying assembly 2 and the negative pressure chamber 6 are both mounted on the bottom plate 23, which not only ensures the relative positional accuracy between components, but also makes the structure of the entire mechanism more compact and reasonable. The material of the bottom plate 23 is selected to be a high-strength, corrosion-resistant metal material, ensuring that it can withstand the weight of the components and the vibration and stress generated during operation without deforming or being damaged during long-term use, thereby maintaining the stability and reliability of the entire mechanism.

[0059] The reset phase mechanism can be modularized for easy assembly with the film processing machine. As shown in the attached drawings of the specification Figure 1 The hexagonal mounting studs are provided on the rear side of the bottom plate 23 for assembly with the film processing machine.

[0060] Specifically, the driving shaft 9 of the equidistant synchronous belt conveying assembly 2 is mounted on the bottom plate 23 through a shaft mounting seat, and the driving shaft 9 passes through the bottom plate 23 to connect with the power source; the driven shaft 12 is also mounted on the bottom plate 23 through a shaft mounting seat. The shaft mounting seat is designed with precision, which not only provides reliable positioning and support for the driving shaft 9 and the driven shaft 12, but also effectively reduces the shaking and deviation of the shaft during rotation. The shaft mounting seat adopts high-precision processing technology to ensure the mating accuracy with the driving shaft 9 and the driven shaft 12, thereby reducing noise and wear caused by excessive mating clearance. The driving shaft 9 passes through the bottom plate 23 to connect with the power source, which ensures that the power can be efficiently and stably transmitted to the equidistant synchronous belt conveying assembly 2 to drive the synchronous belt I 4 and the synchronous belt II 5 to operate. The power source is carefully matched according to the operating requirements and load conditions of the entire mechanism to ensure that it can provide sufficient torque and speed to meet the requirements of sanitary napkin equidistant conveying and phase resetting at different production speeds.

[0061] In addition, the bottom plate 23 is provided with an upper feeding pulley 24 and a lower feeding pulley 25, which are oppositely arranged and are both assembled on the bottom plate 23 through a pulley mounting bracket 26. The upper feeding pulley 24 is used to wrap the upper feeding clamping belt 19, and the lower feeding pulley 25 is used to wrap the lower feeding clamping belt 20. This design enables the upper feeding clamping belt 19 and the lower feeding clamping belt 20 to be stably supported and guided during operation, ensuring the accurate relative position between them and thus guaranteeing the clamping effect on sanitary napkins. The design of the pulley mounting bracket 26 fully considers the tension adjustment needs of the belts. Through the adjustable structure, the operator can easily adjust the tensioning degree of the upper feeding clamping belt 19 and the lower feeding clamping belt 20 according to the actual situation to adapt to the feeding needs of sanitary napkins of different thicknesses and materials. At the same time, the surfaces of the upper feeding pulley 24 and the lower feeding pulley 25 are specially treated to increase the friction between them, preventing the phenomenon of belt slipping during conveying and further improving the stability and reliability of the feeding conveying assembly 1.

[0062] Similarly, the bottom plate 23 is also provided with an upper discharging pulley 27 and a lower discharging pulley 28, which are oppositely arranged and are both assembled on the bottom plate 23 through a pulley mounting bracket 26. The upper discharging pulley 27 is used to wrap the upper discharging clamping belt 21, and the lower discharging pulley 28 is used to wrap the lower discharging clamping belt 22. The upper discharging pulley 27 and the lower discharging pulley 28 play a crucial role in the discharging process. They closely cooperate with the upper discharging clamping belt 21 and the lower discharging clamping belt 22 to ensure that the sanitary napkins after phase resetting can be smoothly and accurately conveyed to the next process. Similar to the feeding pulley, the pulley mounting bracket 26 also has adjustability, which can adjust the tensioning degree of the upper discharging clamping belt 21 and the lower discharging clamping belt 22 according to the actual situation to adapt to different discharging speeds and sanitary napkin characteristics. In addition, the design of the upper discharging pulley 27 and the lower discharging pulley 28 also fully considers the compatibility with the discharging clamping belts, ensuring that the wear between them is minimized during long-term operation, prolonging the service life of the entire discharging conveying assembly 3.

[0063] Through the detailed description of the bottom plate 23 and its related component installation and functions in this embodiment, the overall architecture of the phase resetting mechanism is further improved, making the collaborative work between various components more smooth and stable, providing a solid foundation for achieving efficient and accurate sanitary napkin phase resetting. This not only helps to improve production efficiency, but also further guarantees product quality, meeting the needs of the modern sanitary product production industry for high-precision and high-efficiency production equipment.

[0064] Although the present inventive concept has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details can be made therein without departing from the spirit and scope of the present inventive concept as defined by the appended claims.
