Description

Technical Field

[0001] This utility model relates to the field of noise reduction device technology, specifically a packaging noise reduction device with an air outlet buffer structure. Background Technology

[0002] Vertical packaging machines are typically used for packaging various materials such as powders, granules, liquids, and solids. They require pneumatic systems to drive many key components, such as lifting devices, cutters, and feeding systems. Solenoid valves are the "switching" elements of these systems, responsible for controlling the flow and direction of gas. Since the outlet of the solenoid valve is an important component of the solenoid valve system, it is usually used to regulate and control the direction, flow rate, and pressure of gas flow. In the pneumatic system, the solenoid valve performs the tasks of switching, regulating, or changing by controlling the inlet and outlet of gas. When gas passes through the outlet of the solenoid valve, it generally forms eddies. These eddies will cause vibration, thereby generating noise. Therefore, it is necessary to reduce the noise of the solenoid valves in the vertical packaging machine.

[0003] Because the mesh design of solenoid valve silencers requires a large porosity to allow for smooth airflow, and high-porosity materials are usually thinner, often using thinner, softer metals or plastics, the mechanical strength of these materials is relatively low. This results in these materials typically lacking high impact resistance and being prone to cracking or deformation due to collisions or pressure fluctuations. Therefore, during long-term operation, especially in systems with frequent switching, these pressure fluctuations are more severe, making the solenoid valve silencer susceptible to damage from gas impacts. Thus, we propose a packaging noise reduction device with an exhaust buffer structure. Utility Model Content

[0004] The purpose of this invention is to provide a packaging noise reduction device with an exhaust buffer structure to solve the problem mentioned in the background art, where drastic pressure fluctuations during long-term operation, especially in systems with frequent switching, can easily cause the solenoid valve silencer to break due to gas impact.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a packaging noise reduction device with an air outlet buffer structure, comprising a solenoid valve and a frame plate. The frame plate is sleeved on the outside of the solenoid valve. The inside of the frame plate is sequentially provided with a screw groove and a storage groove. The storage groove is slidably connected to a connecting plate. The upper side of the connecting plate is movably connected to one end of a bolt via a bearing, and the other end of the bolt extends through and out of the inside of the screw groove. The outside of the frame plate is fixed to one end of a support plate. The air outlet of the solenoid valve is connected to an external helical tube, and the outside of the external helical tube is connected to a connecting pipe.

[0006] Preferably, an isolation layer and a connecting layer are sequentially bonded to the outer side of the connecting tube, and the upper side of the connecting tube is fixed to the external spiral tube.

[0007] Preferably, the end of the support plate away from the frame plate is fixed to the perforated box, and the inner side of the perforated box is connected to the internal threaded tube.

[0008] Preferably, the inner helix and the outer helix are connected to each other.

[0009] Preferably, the screw groove is threaded to the bolt, and a rubber pad is bonded to the lower side of the connecting plate.

[0010] Preferably, the external helical tube is threadedly connected to the air outlet of the solenoid valve, and the connecting tube is made of deformable rubber material.

[0011] Preferably, the isolation layer is made of sound-insulating foam material, and the connecting layer is made of deformable nylon film material.

[0012] Preferably, the outer helical tube is threadedly connected to the inner helical tube, and the opening box is made of deformable plastic material.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the solenoid valve is activated, the gas enters the interior of the connecting pipe through the gas outlet of the solenoid valve. The elasticity of the connecting pipe can absorb and weaken the vibration between the airflow and the pipe wall, and the isolation layer can reduce the vibration and sound propagation generated by the connecting pipe. After the air diffuses and flows in the perforated box, it can effectively reduce the impact sound and high-frequency noise of the airflow, so that the packaging noise reduction device can stably reduce the noise of the solenoid valve during long-term operation, especially in systems with frequent switching.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0019] Please see Figures 1-3 This utility model provides a technical solution: a packaging noise reduction device with an air outlet buffer structure, including a solenoid valve 1 and a frame plate 2. The frame plate 2 is sleeved on the outside of the solenoid valve 1. The inside of the frame plate 2 is sequentially provided with a screw groove 201 and a storage groove 202. The storage groove 202 is slidably connected to a connecting plate 203. The upper side of the connecting plate 203 is movably connected to one end of a bolt 204 through a bearing, and the other end of the bolt 204 extends through the inside of the screw groove 201. The outside of the frame plate 2 is fixed to one end of a support plate 205. The air outlet of the solenoid valve 1 is connected to an external screw tube 206, and the outside of the external screw tube 206 is connected to a connecting pipe 207. The outside of the connecting pipe 207 is sequentially bonded with an isolation layer 208 and a connecting layer 209. The upper side of 207 is fixed to the outer threaded tube 210. The end of the support plate 205 away from the frame plate 2 is fixed to the opening box 211, and the inner side of the opening box 211 is connected to the inner threaded tube 212. The inner threaded tube 212 is connected to the outer threaded tube 210. The threaded groove 201 is threadedly connected to the bolt 204. The lower side of the connecting plate 203 is bonded with a rubber pad. The outer threaded tube 206 is threadedly connected to the air outlet of the solenoid valve 1. The connecting tube 207 is made of deformable rubber material. The isolation layer 208 is made of sound-insulating foam material. The connecting layer 209 is made of deformable nylon film material. The outer threaded tube 210 is threadedly connected to the inner threaded tube 212. The opening box 211 is made of deformable plastic material. The inner spacing of the frame plate 2 matches the outer spacing of the solenoid valve 1.

[0020] In specific implementation, according to Figures 1-3Solenoid valve 1 controls the pneumatic system in the vertical packaging machine. By controlling the on / off state, direction, and flow rate of the airflow, solenoid valve 1 can precisely adjust various working stages of the packaging machine, thereby improving packaging accuracy and efficiency, and ensuring the stability and safety of the packaging process. When noise reduction is required for solenoid valve 1, frame plate 2 is fitted onto the outside of solenoid valve 1. The inner spacing of frame plate 2 matches the outer side of solenoid valve 1, making it less prone to shaking. At this time, rotating bolt 204, through the threaded connection between bolt 201 and threaded groove 201, causes bolt 204 to move down along threaded groove 201, pushing connecting plate 203 down to press against the surface of solenoid valve 1. A rubber pad is then adhered to the lower side of connecting plate 203, making... The connecting plate 203 can strengthen the compression limit between the connecting plate and the solenoid valve 1, so that the frame plate 2 is restricted to the outside of the solenoid valve 1. At this time, the opening box 211 is located above the air outlet of the solenoid valve 1. Then, the outer threaded tube 206 is rotated and connected to the air outlet of the solenoid valve 1. The outer threaded tube 206 is threadedly connected to the air outlet of the solenoid valve 1, so that the outer threaded tube 206 is restricted to the air outlet of the solenoid valve 1. Then, the outer threaded tube 210 is rotated and connected to the inner threaded tube 212. The outer threaded tube 210 is threadedly connected to the inner threaded tube 212, so that the outer threaded tube 210 is restricted to the inner threaded tube 212. At this time, the two ends of the connecting tube 207 are restricted to the solenoid valve 1 and the opening box 211 respectively through the outer threaded tube 206 and the outer threaded tube 210. After solenoid valve 1 is activated, gas enters the connecting pipe 207 through the outlet of solenoid valve 1. The connecting pipe 207, made of deformable rubber, provides excellent cushioning and shock absorption. When airflow enters the connecting pipe 207 through the outlet of solenoid valve 1, the elasticity of the connecting pipe 207 absorbs and weakens the vibration between the airflow and the pipe wall, reducing resonance and thus reducing vibration transmission to the external environment. Furthermore, the larger inner diameter at one end of the connecting pipe 207 allows for smoother airflow and reduces abrupt changes in compressed gas within the pipe, thereby reducing the noise generated by solenoid valve 1. The sound-absorbing foam material in the isolation layer 208 further absorbs and dampens vibrations, reducing noise transmission and further minimizing the vibration and sound propagation generated by the connecting pipe 207, thus reducing noise. Noise generated by vibration is mitigated by the use of a deformable nylon film material in the connecting layer 209, which possesses high mechanical strength and wear resistance. This effectively protects the isolation layer 208 from external physical damage, especially during long-term use. The connecting layer 209 prevents wear, tearing, or breakage of the isolation layer 208 surface, thus extending its service life. When airflow exits through the perforated box 211, its speed is reduced. The diffusion and flow of air within the perforated box 211 effectively reduces the impact sound and high-frequency noise of the airflow. Furthermore, the perforation design of the perforated box 211 typically avoids sudden changes in airflow, thereby reducing noise generated by airflow impact. The use of a deformable plastic material in the perforated box 211 provides a degree of elasticity.This further reduces the vibration or impact generated during the operation of solenoid valve 1, preventing vibration from propagating through the pipeline and affecting other components or increasing noise. This ensures that the packaging noise reduction device can stably reduce noise from solenoid valve 1 during long-term operation, especially in systems with frequent switching.

[0021] In summary, when noise reduction is required for solenoid valve 1, frame plate 2 is placed outside solenoid valve 1, and the two ends of connecting pipe 207 are respectively bound to solenoid valve 1 and opening box 211 through external helical tube 1 206 and external helical tube 210. When solenoid valve 1 is activated, gas enters the interior of connecting pipe 207 through the gas outlet of solenoid valve 1. The elasticity of connecting pipe 207 can absorb and weaken the vibration between airflow and pipe wall, and the isolation layer 208 can reduce the vibration and sound propagation generated by connecting pipe 207. When airflow is discharged through opening box 211, the air diffusion and flow within opening box 211 can effectively reduce the impact sound and high-frequency noise of airflow. This allows the packaging noise reduction device to stably reduce noise for solenoid valve 1 during long-term operation, especially in systems with frequent switching.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
