[0002] In the field of atomizer technology, the cotton core is one of the key components, and its quality and shape directly affect the atomization effect, taste and overall performance of the product. Traditionally, the production process of atomizer cotton cores often relies on manual operations, such as manually cutting cotton pieces with scissors or blades. This manual method is not only inefficient, but also difficult to ensure the consistency, uniformity and precision of the cotton core size, which in turn affects the atomization efficiency and stability.

[0003] With the rapid development of the market, the requirements for atomizer performance are increasing day by day, especially the preparation process of cotton cores has put forward higher standards.

DETAILED DESCRIPTION

[0020] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0021] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure. Example

[0022] like Figures 1-4 As shown, the utility model provides a pneumatic cotton cutting jig, including a bottom plate 1, a pad 2 arranged above the bottom plate 1, a cylinder body 4 fixedly connected to the pad 2, an air cavity 41 inside the cylinder body 4, an air valve 8 arranged at the rear of the cylinder body 4, and a shearing head 5 and a shearing handle 51 arranged at the front end of the cylinder body 4, and also includes a storage table 6 for assisting in positioning an atomizer assembly 7, the storage table 6 is installed in front of the shearing head 5 and fixedly connected to the bottom plate 1;

[0023] A cylindrical middle cavity 9 is provided between the air cavity 41 and the air valve 8, and the middle cavity 9 is connected with an air inlet hole 44 and an air outlet hole 45. The air inlet hole 44 and the air valve 8 are coaxially connected to the cylinder wall and the air outlet hole 45 is provided on the side of the middle cavity 9 and is connected to the cylinder. The middle cavity 9 is provided with a normally tilted elastic sheet 81, and one end of the elastic sheet 81 is fixed to the wall of the middle cavity 9.

[0024] When the air valve 8 takes in air, the gas pushes the elastic sheet 81 to block the exhaust hole 45. Continuous inflation pushes the movable block 42 forward to close the scissors and compress the spring 43. When inflation and exhaust stop, the elastic sheet 81 rebounds to open the exhaust hole 45, and the spring 43 rebounds to push the movable block 42 to discharge the gas in the air cavity 41.

[0025] A movable block 42 that can move forward and backward is arranged in the air cavity 41 . The movable block 42 pushes the shear handle 51 to close the shear head 5 . A spring 43 is also arranged on the front side of the movable block 42 .

[0026] When the air valve 8 is closed and the air pressure in the air cavity 41 decreases, the elastic force of the spring 43 pushes the movable block 42 to move backward, thereby separating the shearing head 5 and the shearing handle 51 and returning to the initial state. This reset function ensures that the shears can automatically return to its original position after each shearing, ready for the next shearing.

[0027] When the air valve 8 is opened and the air pressure in the air chamber 41 increases to push the movable block 42 to move forward, the spring 43 is compressed. The compression force of the spring 43 plays an auxiliary shearing role in this process, increasing the force when the cutting head 5 and the cutting handle 51 are closed, which helps to cut the cotton sheet of the atomizer assembly 7 more thoroughly.

[0028] During the shearing process, the spring 43 can absorb part of the impact force and vibration. When the cutting head 5 and the cutting handle 51 contact the cotton sheet and apply the shearing force, the buffering effect of the spring 43 makes the shearing process smoother, reducing the damage to the cutting tool itself and the atomizer assembly 7.

[0029] By adjusting the elastic force of the spring 43, the moving stroke of the movable block 42 can be accurately controlled, which helps to ensure that the cutting head 5 and the cutting handle 51 reach the predetermined shearing position when closed, thus ensuring the shearing accuracy.

[0030] The presence of the spring 43 makes the cutting head 5 and the cutting handle 51 not directly impact each other when closed, but gradually contact through the buffering effect of the spring 43. This design reduces the direct wear between the cutting head 5 and the cutting handle 51 and extends the service life of the cutting tool.

[0031] See Figure 2 , the shape of the cutting handle 51 is arc-shaped, and the movable block 42 is provided with a groove 421, and the groove 421 is consistent with the shape of the cutting handle 51.

[0032] The matching design of the groove 421 and the arc-shaped cutting handle 51 ensures the accurate guidance of the cutting handle 51 on the movable block 42. When the gas pressure pushes the movable block 42 to move forward, the cutting handle 51 can smoothly move along the track of the groove 421, thus realizing the accurate closing of the cutting head 5. This design reduces the deviation and shaking during the movement of the cutting handle 51 and improves the accuracy of the shearing action.

[0033] The close fit of the arc-shaped cutting handle 51 and the groove 421 enhances the stability of the cutting handle 51 during movement. The groove 421 provides a stable supporting surface for the cutting handle 51, making the cutting handle 51 not easy to tilt or twist when stressed, thus ensuring the stability and consistency of the shearing action.

[0034] The matching design of the groove 421 and the cutting handle 51 also facilitates the maintenance and replacement of the fixture. When the cutting handle 51 or the movable block 42 is worn or damaged, it can be disassembled and replaced more easily, reducing the maintenance difficulty and cost.

[0035] See Figure 1 , the backing plate 2 is provided with strip-shaped holes 3, and the strip-shaped holes 3 are arranged in parallel on both sides of the cylinder block 4. The strip-shaped holes 3 are used to adjust the position of the cylinder block 4.

[0036] The strip-shaped holes 3 allow for fine position adjustment of the cylinder block 4 to adapt to different working requirements or optimize the shearing effect. By adjusting the position of the cylinder block 4 on the backing plate 2, it can be ensured that the cutting head 5 and the cutting handle 51 can accurately align with the material to be sheared, improving the shearing accuracy.

[0037] See Figure 3 and Figure 4 , the elastic sheet 81 is a rubber elastic sheet 81.

[0038] The rubber elastic sheet 81 has good sealing performance, which can effectively prevent gas from leaking from the air inlet hole 44 or the exhaust hole 45 of the intermediate cavity 9, ensuring that the gas pressure in the air cavity 41 can stably act on the movable block 42 to push it to perform the shearing action.

[0039] When the air valve 8 is opened and gas enters the intermediate cavity 9 through the air inlet hole 44, the rubber elastic sheet 81 will undergo elastic deformation and evenly transmit the gas pressure to the inside of the air cavity 41. This uniformity of pressure transmission helps to ensure the smoothness and consistency of the shearing action.

[0040] See Figure 3 and Figure 4 , the elastic sheet 81 is a unidirectional bending spring piece.

[0041] The unidirectional bending spring piece has high bending sensitivity and stiffness in a specific direction, while being relatively less bendable in other directions. This property enables it to produce precise bending deformation when subjected to pressure or force in a specific direction, thereby achieving precise control of the shearing action.

[0042] When the air valve 8 is opened and gas enters the intermediate cavity 9 through the air inlet hole 44, the unidirectional bending spring piece will undergo bending deformation under the action of the gas pressure. This deformation effectively transmits the gas pressure to the movable block 42 inside the air cavity 41 to push it to perform the shearing action. Due to the precision of the unidirectional bending spring piece, this pressure transmission process is more efficient and stable.

[0043] See Figure 3 and Figure 4 , the cross-section of the spring 43 is rectangular.

[0044] Due to the characteristics of its cross-sectional shape, the rectangular spring 43 has greater stiffness than the circular cross-section spring 43 under the same space conditions. This means that under the same pressure, the rectangular spring 43 can generate a greater reaction force, thus more effectively pushing the movable block 42 to perform the shearing action.

[0045] The mechanical property curve of the rectangular spring 43 is closer to a straight line and the stiffness is closer to a constant, which enables it to provide more stable elastic force and supporting force during operation, helping to maintain the accuracy and consistency of the shearing action.
