The fineness of the graphic part is ultimately determined by the piston rod and the nearly dozens of material distribution cylinders arranged side by side in the material distribution device. The movement speed of the material distribution cylinder determines the fineness of the pattern, but the movement speed of the cylinders currently on the market is limited. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] Combine the following Figures 1 to 5 Embodiments of the present invention are described.

[0032] The present embodiment relates to a high-speed integrated cylinder for distributing ceramic powder.

[0033] Ceramic powder refers to a powder material used in the production process of ceramic products. In ceramic feeding technology, the feeding cylinder is a key component, which directly affects the accuracy and efficiency of feeding. When feeding, the conveyor belt and the feeding cylinders arrayed along the width of the conveyor belt cooperate with each other, and the feeding cylinders are started in sequence according to the set program to release the powder at the corresponding position, thereby realizing graphical feeding.

[0034] When distributing powder, the running speed of the distributing cylinder determines the fineness and efficiency of the distributing. In order to improve the running speed of the distributing cylinder, the present invention proposes a high-speed integrated cylinder.

[0035] A high-speed integrated cylinder in this embodiment includes:

[0036] A cylinder body 1, wherein a slide rod hole 10 is provided in the cylinder body 1, wherein the slide rod hole 10 includes a propulsion section 101, a return section 102 and a guide section 103 in sequence, wherein the propulsion section 101, the return section 102 and the guide section 103 are arranged in sequence, wherein the inner diameters of the propulsion section 101, the return section 102 and the guide section 103 are successively smaller, wherein a propulsion air port 14 is provided on a side of the propulsion section 101 away from the return section 102, and a second air inlet 15 is provided on the return section 102;

[0037] The push rod 2 includes a straight rod 23, a propulsion block 21, and a return block 22. The propulsion block 21 is located in the propulsion section 101. The propulsion block 21 and the return block 22 are both arranged on the straight rod 23. The propulsion block 21 slides along the axial direction of the propulsion section 101. The propulsion block 21 includes a propulsion surface 212 facing the propulsion air port 14. The outer wall of the propulsion block 21 is sealed with the inner wall of the propulsion section 101. The return block 22 is located in the return section 102. The outer wall of the return block 22 is sealed with the inner wall of the return section 102. The return block 22 includes a return surface 222 facing the second air inlet 15. The area of ​​the propulsion surface 212 is larger than that of the return surface 222. The return block 22 slides along the axial direction of the return section 102. The straight rod 23 slides along the guide section 103 and extends out of the guide section 103. The straight rod 23 is used to drive external components.

[0038] The high-speed integrated cylinder is configured with a propulsion section 101, a return section 102 and a guide section 103 with successively smaller inner diameters. The push rod 2 includes a straight rod 23, a propulsion block 21 and a return block 22. Since the area of ​​the propulsion surface 212 is larger than the return surface 222, when compressed gas is supplied, the propulsion force exerted on the push rod 2 by the pressure of the compressed gas through the propulsion surface 212 is greater than the return force exerted on the return block 22 by the pressure of the compressed gas through the return surface 222. When the compressed gas is supplied to push the push rod 2 out, the pressure difference between the propulsion force and the return force of the push rod 2 is increased, thereby effectively increasing the propulsion force of the push rod 2.

[0039] The propulsion port 14 is connected to a solenoid valve, which controls the opening and closing of the propulsion port 14. When compressed air is introduced into the propulsion port 14, the solenoid valve on the propulsion port 14 is opened, and the compressed gas acts on the propulsion surface 212. Since the area of ​​the propulsion surface 212 is large, a large thrust is generated to push the push rod 2 forward.

[0040] When the push rod 2 needs to return, the solenoid valve is closed. At this time, there is no compressed air pressure in the propulsion section 101, and the compressed air from the second air inlet 15 acts on the return surface 222. Due to the action of the compressed air, the pressure on the surface 222 is greater than that on the surface 212, and the push rod 2 returns under the action of 222.

[0041] The design of this high-speed integrated cylinder achieves efficient and stable pushing and returning actions through precise air port settings, inner diameter changes and push rod 2 structure. Its characteristics are the difference in area between the pushing surface 212 and the returning surface 222, as well as the three-stage design of the slide rod hole 10, which help to improve the working efficiency and stability of the cylinder. In addition, the design of the straight rod 23 enables the cylinder to directly drive external components, increasing its flexibility and wide application.

[0042] In this embodiment, the outer diameter of the straight rod 23 matches the inner diameter of the guide section 103, ensuring that the push rod 2 slides smoothly in the guide section 103. One end of the straight rod 23 is connected to the push block 21, and the other end extends out of the guide section 103 to facilitate connection with external equipment or mechanical parts. The shapes of the push block 21 and the return block 22 are designed to be suitable for sliding in their respective sections and closely fit with the inner wall of the cylinder body 1 to reduce gas leakage and improve the sealing performance of the cylinder.

[0043] In practical applications, the high-speed integrated cylinder can be installed on a ceramic material distribution machine to control the release of powder during the material distribution process. By accurately controlling the gas flow and pressure of the propulsion port 14 and the second air inlet 15, the movement speed and force of the push rod 2 can be accurately controlled, thereby improving the accuracy and efficiency of material distribution. In addition, the design of the cylinder also allows it to be used in other industrial applications that require high-speed and high-precision control, such as in automated assembly lines, precision positioning equipment and other fields.

[0044] Furthermore, a chamfered surface is provided on a side of the propulsion block 21 facing the propulsion air port 14 .

[0045] The chamfered bevel is designed to reduce the friction resistance between the propulsion block 21 and the airflow, thereby improving the propulsion efficiency. By optimizing the angle and shape of the bevel, the gas flow can be further optimized to ensure that the airflow passes smoothly through the propulsion port 14 and reduce energy loss. At the same time, the chamfered bevel also has a certain guiding effect, which can guide the airflow to flow in a predetermined direction to ensure stability and accuracy during the propulsion process. This design not only improves the overall performance of the propulsion system, but also reduces operating noise and improves user experience. During the manufacturing process, the accuracy and surface quality of the chamfered bevel are strictly controlled to ensure that it meets the design requirements.

[0046] The straight rod 23 is provided with a sealing pad, which is located on the side of the propulsion block 21 facing the return block 22. A first sealing groove 211 is formed between the propulsion block 21 and the sealing pad. A first sealing ring 3 is provided at the first sealing groove 211. The first sealing ring 3 is sleeved outside the straight rod 23. The outer diameter of the first sealing ring 3 in a free state is the inner diameter of the return section 102, so that when the first sealing ring 3 enters the return section 102 from the top of the return section 102, the bottom side of the first sealing ring 3 can buffer the propulsion block 21 and then enter the return section 102. The provision of the first sealing ring 3 further strengthens the sealing effect between the propulsion block 21 and the return section 102. Under the action of gas pressure, the first sealing ring 3 fits tightly on the inner wall of the return section 102, effectively preventing gas leakage and ensuring the high-pressure environment inside the cylinder, thereby improving the working efficiency of the cylinder and the stability of thrust output. When the push rod 2 is in the process of advancing, the first sealing ring 3 moves with the straight rod 23, and when entering the return section 102, its bottom side first contacts the entrance of the return section 102. Since the outer diameter of the first sealing ring 3 in the free state is slightly larger than the inner diameter of the return section 102, this design enables the first sealing ring 3 to play a buffering role when entering the return section 102, slowing down the direct impact between the thrust block 21 and the inner wall of the return section 102, reducing the noise and vibration during the movement, and improving the stability of the cylinder operation. After the first sealing ring 3 enters the return section 102, the friction between the first sealing ring 3 and the inner wall of the return section 102 helps to decelerate the push rod 2 in advance, reducing the impact force of the thrust head reaching the lower end of the stroke and colliding with the interface between the return section 102 and the thrust section 101, which is conducive to improving the service life of the push rod 2. In addition, the presence of the first sealing ring 3 enables the push rod 2 to maintain better linearity and stability during the movement. Due to the elastic effect of the sealing ring, it can correct the slight deviation of the push rod 2 caused by external load or manufacturing error to a certain extent, thereby improving the movement accuracy and positioning accuracy of the cylinder.

[0047] Specifically, the first sealing ring 3 is provided with a material reduction groove 31 on the side facing away from the propulsion block 21, and the material reduction groove 31 is located in the middle area of ​​the sealing ring. The setting of the material reduction groove 31 affects the stress distribution of the first sealing ring 3 under pressure. When the gas pressure is applied to the first sealing ring 3, due to the existence of the material reduction groove 31, the pressure in the middle area of ​​the sealing ring is released, while the edge area maintains a higher pressure level. This optimized configuration of pressure distribution helps to alleviate the deformation problem of the sealing ring caused by uneven pressure distribution, thereby ensuring its excellent sealing performance. The design of the material reduction groove 31 also enhances the elasticity of the first sealing ring 3. During the movement of the push rod 2, when the first sealing ring 3 contacts the inner wall of the return section 102, the material reduction groove 31 can play a role similar to a spring, absorb part of the impact force, and play an effective buffering effect. This design not only reduces the direct impact between the sealing ring and the inner wall, but also effectively reduces the noise and vibration generated during the movement.

[0048] Furthermore, the material reduction groove 31 is in a "V" shape, and the first sealing ring 3 is tilted outward outside the material reduction groove 31. The "V"-shaped material reduction groove 31 and the outward tilting design work together to enable the first sealing ring 3 to better fit the inner wall of the return section 102 when under pressure, forming a tight seal to prevent gas leakage. The outward tilting design reduces the contact area between the sealing ring and the inner wall of the return section 102, thereby reducing the movement resistance. This not only makes the movement of the push rod 2 smoother, but also reduces the energy consumption of the cylinder.

[0049] Furthermore, the portion of the first sealing ring 3 within the material reduction groove 31 is tilted inward. When the gas pressure acts on the first sealing ring 3, the inward tilting design can guide the pressure to concentrate on the center of the sealing ring and disperse it through the material reduction groove 31. This design helps to avoid the pressure from forming local high pressure on the surface of the sealing ring, thereby reducing the risk of deformation and damage to the sealing ring. A wedge-shaped sealing structure is formed between the inward tilted portion and the inner wall of the return section 102. Under the action of gas pressure, this structure can fit together more closely, thereby enhancing the sealing effect. Even under high pressure conditions, stable sealing performance can be maintained. At the same time, the inward tilting design makes it easier for the first sealing ring 3 to be compressed and slide into the return section 102 during installation, reducing the difficulty of installation. Similarly, during disassembly, this design also helps the sealing ring to slide out of the return section 102 more easily, reducing the time and effort during maintenance.

[0050] The return block 22 is provided with a second sealing groove 221, and the second sealing groove 221 is located at the second air inlet 15, and a second sealing ring 4 is provided near the second sealing groove 221, and the inner wall of the second sealing ring 4 abuts against the inner wall of the second sealing groove 221, and the outer wall of the second sealing ring 4 abuts against the return section 102. The arrangement of the second sealing groove 221 and the second sealing ring 4 can ensure that when the compressed gas enters from the second air inlet 15, it is effectively blocked by the second sealing ring 4 to prevent gas leakage.

[0051] Specifically, the cylinder body 1 includes an upper body 11 and a lower body 12, the lower side of the upper body 11 is provided with the propulsion section 101, the lower body 12 is provided with a return section 102, and the upper body 11 and the lower body 12 are sealed and connected. The cylinder body 1 of the cylinder is composed of the upper body 11 and the lower body 12, and the two are sealed and connected by a strict method such as threaded connection or welding, thereby ensuring the airtightness of the cylinder. The guide plate 13 is firmly installed on one side of the lower cylinder body 1, and the sliding hole provided thereon is used to guide the sliding of the straight rod 23. The design of the guide plate 13 is intended to optimize the motion trajectory of the push rod 2 and effectively reduce the deviation and vibration phenomenon.

[0052] In addition, the sealing connection between the upper body 11 and the lower body 12 adopts a threaded connection or welding connection method, which not only has a high degree of firmness and reliability, but also can effectively prevent gas leakage, thereby further ensuring the airtightness of the cylinder. The modular design of the cylinder allows its various components to be processed in parallel, significantly shortening the overall production cycle. At the same time, the design also makes the assembly process simpler and faster, effectively reducing the manufacturing cost.

[0053] The cylinder body 1 further includes a guide plate 13, which is arranged on a side of the lower cylinder body 1 away from the upper cylinder body 1, and the slide hole is arranged on the guide plate 13. The separate structural design allows the guide plate 13 and its slide hole to be maintained and replaced independently of other components of the cylinder body 1. When the guide plate 13 or the slide hole needs to be repaired due to wear, there is no need to disassemble the entire cylinder body 1, which effectively reduces the complexity and cost of maintenance. The guide plate 13 and its slide hole have been treated with wear resistance and lubrication, which can significantly reduce friction and wear, thereby extending the service life of the cylinder. In addition, this design also reduces the heat and noise generated by friction, and improves the working efficiency of the cylinder.

[0054] The present invention also provides an embodiment of a material distributing device, comprising the high-speed integrated cylinder described in any one of the embodiments, wherein the number of the high-speed integrated cylinders is multiple, and the high-speed integrated cylinders are all driven and connected to a discharge baffle, and the high-speed integrated cylinder drives the discharge baffle to move to discharge the powder.

These equivalent modifications or substitutions are all included in the scope defined by the claims of the present disclosure.
