Description

Technical Field

[0001] This invention relates to the field of equipment housing preparation devices, specifically a housing blowing mechanism for industrial Internet of Things (IoT). Background Technology

[0002] In industrial production, product casings need to be prepared before leaving the factory to ensure product quality. One important step is to blow-dry the casing to remove impurities. Since products come in different specifications and sizes, different specifications of blowing equipment are needed to handle the different sizes of product casings.

[0003] Because it is necessary to avoid the impurities on the casing being blown out of control, existing technologies generally blow the casing within a set space. In order to adapt to different product specifications, the blowing task is usually carried out by ventilating a large area within the set space. However, most casings are not regular in shape, so there are many dead corners that cannot be blown out by large-area ventilation, which greatly limits the blowing of the casing.

[0004] The Industrial Internet of Things (IIoT) is a factory production technology that uses IoT technology to efficiently integrate all aspects of industrial production.

[0005] In the application of Industrial Internet of Things (IIoT), the connection between various links needs to be stable and efficient. Improving equipment utilization is also an important part of the IIoT application process, which can effectively improve production efficiency and reduce production costs. In the process of shell purging, it is not only necessary to complete the shell purging work stably and efficiently, but also to adapt the shell purging mechanism to different shell shapes so that the equipment can be used more effectively. Therefore, how to avoid purging dead spots while ensuring purging of different product specifications has become an urgent problem to be solved in the field of shell preparation equipment. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies in that they cannot cover blind spots and adapt to various product specifications when blowing out housings. It provides a housing blowing mechanism for industrial Internet of Things, which uses several air knife components to blow out the housing surface. By floating the air knife components, the blowing space can be adjusted with the floating of the air knife components, thus covering blind spots and adapting to the blowing of housings of various specifications by changing the boundary of the blowing space.

[0007] The objective of this invention is mainly achieved through the following technical solutions:

[0008] A shell purging mechanism for industrial Internet of Things includes a chassis, wherein a plurality of air knife assemblies are arranged inside the chassis, the air knife assemblies are arrayed inside the chassis, and a purging space is formed between the air knife assemblies;

[0009] The air knife assembly is floatingly installed inside the chassis, and the boundary of the purging space can change with the floating of the air knife assembly.

[0010] Currently, when preparing products, the outer casing needs to be purged. During the purging process, because the outer casing itself has an irregular shape, it is necessary to purge the outer casing from multiple angles. However, the purging space cannot be too wide, as an overly wide purging space will result in poor purging effect and will also lead to a significant waste of resources if the air force cannot be effectively applied to the outer casing.

[0011] In this embodiment, a purging space is composed of several air knife assemblies. Since the air force exerted on the outer shell by the air knife assemblies at the boundary of the purging space maintains a different angle, it can adapt to the irregular shape of the outer shell, allowing more parts of the outer shell to be purged. The boundary of the purging space formed by the multiple air knife assemblies is determined by each air knife assembly. Therefore, when the air knife assembly is set to floating installation, the boundary of the purging space can be adjusted by changing the position of the air knife assembly, thereby adapting to more specifications of outer shells. In this embodiment, the floating installation means that the air knife assembly can adjust its position and purging angle within the range of the chassis, thereby adapting to more purging environments, eliminating purging dead corners, and adapting to more purging specifications.

[0012] Furthermore, the air knife assembly includes a base, which is fixed to the chassis. A guide rod is provided on the base, and a guide rod floating support is provided on the guide rod. An air knife is installed on the guide rod floating support, and the guide rod floating support can slide or be fixed along the guide rod.

[0013] A speed control valve is provided on the air knife.

[0014] In this embodiment, the base is used to fix the guide rod, thereby providing a support foundation for the air knife assembly. The guide rod is used to limit the floating support of the guide rod, so that the floating support of the guide rod can only be adjusted along the direction of the guide rod. This ensures that the position of the air knife is controllable and avoids uncontrolled adjustment of the purging space. The air force of the air knife is controlled by a speed regulating valve.

[0015] Furthermore, a stabilizing extension rod is provided between the guide rod floating support and the air knife, and there is an angle between the stabilizing extension rod and the guide rod. The stabilizing extension rod can extend and retract on the guide rod floating support.

[0016] In this embodiment, the stabilizing extension rod can not only adjust its position within the chassis by extending and retracting on the guide rod floating support, but also allow the air knife to extend to more positions within the chassis by the angle between the stabilizing extension rod and the guide rod. This makes the boundary adjustment of the purging space more flexible and enhances its adaptability to various product housing specifications.

[0017] Furthermore, the stabilizing extension rod includes an outer tube, inside which a support rod is provided, one end of which extends out of the outer tube and the other end of which is inserted into the outer tube;

[0018] An elastic airbag is provided between the support rod and the inner wall of the outer sleeve. The elastic airbag is provided with a connecting pipe, which is connected to an air pump. The air pump can adjust the internal pressure of the elastic airbag according to the wind speed of the air knife: when the wind speed of the air knife is high, the internal pressure of the elastic airbag is increased; when the wind speed of the air knife is low, the internal pressure of the elastic airbag is decreased.

[0019] In this embodiment, the air force of the air knife can be increased or decreased as needed. When the air speed of the air knife is increased, due to the limited space of the housing, the chassis, guide rod, and other components are prone to violent shaking under the action of the air knife. This shaking can cause the air knife to vibrate, which not only affects the control of the air knife's position but also risks causing localized damage to the housing. The purpose of this application is only to blow the housing, so it is necessary to eliminate the risk of the air knife impacting the housing to the greatest extent possible. Therefore, it is necessary to control the amplitude of the air knife while avoiding fatigue of the support rod. The support rod mentioned in this application is used to interact with the guide rod. The air knife is connected to the support rod, so the vibration of the air knife is transmitted directly through the outer sleeve to the support rod. The elastic airbag forms a buffer between the support rod and the outer sleeve. Depending on the air knife speed, if the air knife speed is high, the vibration will definitely intensify. At this time, the support of the elastic airbag needs to be relatively stiff. Therefore, pressure can be added to the elastic airbag to improve its support capacity. If the air knife speed is low, the vibration is slowed down. At this time, it is even more important to maintain the stability and safety of the support rod. Therefore, the internal pressure of the elastic airbag can be reduced, so its support is relatively soft, thereby improving the buffering capacity of the elastic airbag. This can effectively protect the support rod.

[0020] Furthermore, an internal pressure regulating valve is provided between the connecting pipe and the air pump, which can adjust the gas flow rate by adjusting the pressure difference between the inside and outside of the elastic airbag.

[0021] In this embodiment, the internal pressure of the elastic airbag is assisted by an internal pressure regulating valve. This ensures that the internal pressure of the elastic airbag is adapted to the wind speed of the air knife, and prevents the pressure difference between the inside and outside of the elastic airbag from becoming too large, thus protecting the elastic airbag from damage due to the pressure difference.

[0022] Furthermore, the internal pressure regulating valve includes a pressure regulating pipe, one end of which is connected to an air pump, and the other end of which is connected to a connecting pipe. A conical valve body is provided inside the pressure regulating pipe. The diameter of the opening at the end of the conical valve body near the air pump is smaller than the diameter of the opening at the end near the connecting pipe. A sealing ball capable of blocking the opening at the end of the conical valve body near the air pump is provided inside the conical valve body. A first elastic adjusting element is provided between the sealing ball and the conical valve body. A supporting inclined surface is fixed at the end of the conical valve body near the connecting pipe. A second elastic adjusting element is provided between the supporting inclined surface and the sealing ball.

[0023] In this embodiment, the pressure regulating pipe is used to withstand pressure changes at both ends, and the strength of the material used should be higher than that of the connection end of the connecting pipe and the air pump. The conical valve body is beneficial for the sealing ball to block the channel, and the supporting inclined surface is used to provide fixed support for the second elastic adjusting member.

[0024] In this embodiment, the blocking ball controls the internal pressure through the combined action of the first and second elastic adjustment components. The elastic support force of the first and second elastic adjustment components can be adjusted to meet different needs. For example, when springs are used as the first and second elastic adjustment components, the elastic force can be adjusted by replacing the springs. The combined action of the first and second elastic adjustment components allows for more flexible setting of the elastic force, thereby enabling the elastic airbag to exert its maximum effectiveness under different working conditions.

[0025] Furthermore, a friction pad is provided between the elastic airbag and the support rod, and the friction pad is fixed to the elastic airbag and in contact with the support rod.

[0026] In this embodiment, the position of the support rod is fixed by the friction of the friction pad, preventing the support rod from coming out of the outer tube during operation.

[0027] Furthermore, the port of the outer tube is provided with a plug, and the plug is fixed to the outer tube;

[0028] The support rod is provided with an inner insert rod. One end of the inner insert rod is inserted into the support rod, and the other end is fixed to the outer tube. Several triangular supports are provided between the inner insert rod and the inner wall of the outer tube. The triangular supports are fixed to the inner insert rod and the inner wall of the outer tube.

[0029] In this embodiment, the outer tube has a plug at its port to prevent excessive deformation of the elastic airbag. The inner rod guides the support rod by inserting into it, preventing the support rod's axis from shifting. Furthermore, the inner part of the outer tube is reinforced by triangular supports, which increases the strength of the outer tube and controls its weight.

[0030] Furthermore, the stabilizing extension rod is provided with a stabilizing floating support, which can slide or be fixed along the stabilizing extension rod;

[0031] The air knife is mounted on the stable floating support.

[0032] The stable floating support provided on the stable extension rod in this embodiment can adjust the position of the air knife by sliding on the stable support rod, thereby increasing the adjustment range of the boundary of the purging space.

[0033] Furthermore, a solenoid valve is provided on the chassis, and the solenoid valve is connected to the inside of the chassis;

[0034] The bottom of the chassis is equipped with a water receiving tank, which is connected to the chassis, and the bottom of the water receiving tank is equipped with a water inlet.

[0035] In this embodiment, the solenoid valve is used to connect the inside and outside of the chassis, so that the pressure inside the chassis is maintained in balance. The water tank can receive impurities, including moisture, that fall from the surface of the outer casing during the purging process. The water inlet can discharge the water in the water tank in a timely manner to prevent it from becoming full.

[0036] In summary, the present invention has the following advantages compared with the prior art:

[0037] (1) The floating installation of the present invention means that the air knife assembly can adjust its position and blowing angle within the range of the chassis, thereby adapting to more blowing environments, eliminating blowing dead angles, and adapting to more blowing specifications.

[0038] (2) The support rod described in this invention is used to connect with the guide rod. Therefore, the vibration of the air knife is transmitted most directly through the outer sleeve to the support rod. The elastic airbag forms a buffer between the support rod and the outer sleeve. According to the change of the air knife wind speed, if the air knife wind speed is high, the vibration will definitely intensify. At this time, the support of the elastic airbag needs to be relatively stiff. Therefore, pressure can be added to the elastic airbag to improve its support capacity. If the air knife wind speed is low, the vibration is slowed down. At this time, it is even more necessary to maintain the stability and safety of the support rod. Therefore, the internal pressure of the elastic airbag can be reduced to make its support relatively soft, thereby improving the buffer capacity of the elastic airbag. This can effectively protect the support rod. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0046] Example:

[0047] like Figures 1-4 As shown, a shell purging mechanism for industrial Internet of Things includes a housing 3, and a plurality of air knife assemblies 2 are provided inside the housing 3. The air knife assemblies 2 are arranged in an array inside the housing 3, and a purging space is formed between the air knife assemblies 2.

[0048] The air knife assembly 2 is floatingly installed inside the chassis 3, and the boundary of the purging space can change with the floating of the air knife assembly 2.

[0049] In this embodiment, the chassis 3 provides sufficient space for purging the outer shell and restricts the purging environment, preventing external influences while ensuring sufficient purging effect. This embodiment uses several air knife assemblies 2 to form the purging space. Since the air force exerted on the outer shell by the air knife assemblies 2 at different angles along the boundary of the purging space, it can adapt to the irregular shape of the outer shell, allowing more parts of the shell to be purged. The boundary of the purging space formed by the multiple air knife assemblies 2 is determined by each air knife assembly 2. Therefore, when the air knife assembly 2 is set to floating installation, the boundary of the purging space can be adjusted by changing the position of the air knife assembly 2, thus adapting to more sizes of outer shells. The floating installation in this embodiment is an adjustable fixed installation; the position of the air knife assembly 2 within the chassis 3 can be adjusted and then fixed in that position.

[0050] The air knife assembly 2 includes a base 27, which is fixed to the chassis 3. A guide rod 21 is provided on the base 27, and a guide rod floating support 22 is provided on the guide rod 21. An air knife 25 is installed on the guide rod floating support 22. The guide rod floating support 22 can slide or be fixed along the guide rod 21.

[0051] A speed regulating valve 26 is provided on the air knife 25.

[0052] A stabilizing extension rod 23 is provided between the guide rod floating support 22 and the air knife 25. There is an angle between the stabilizing extension rod 23 and the guide rod 21. The stabilizing extension rod 23 can extend and retract on the guide rod floating support 22.

[0053] The base is used to fix the guide rod 21, thereby providing a support foundation for the air knife assembly 2. The guide rod 21 is used to limit the guide rod floating support 22, so that the guide rod floating support 22 can only be adjusted along the direction of the guide rod 21. This way, the position of the air knife 25 can be controlled, avoiding the loss of control over the adjustment of the purging space. The air force of the air knife 25 is controlled by the speed regulating valve 26.

[0054] In this embodiment, the blowing angle of the air knife 25 can be adjusted by the fixed position and rotation angle of the stabilizing extension rod 23 on the guide rod floating support 22, thereby targeting the blowing dead angle for different shells and avoiding the existence of blowing dead angles to a certain extent.

[0055] The stabilizing extension rod 23 includes an outer tube 232, and a support rod 231 is provided inside the outer tube 232. One end of the support rod 231 extends out of the outer tube 232, and the other end is inserted into the outer tube 232.

[0056] An elastic airbag 233 is provided between the support rod 231 and the inner wall of the outer sleeve 232. The elastic airbag 233 is provided with a connecting pipe 235, and the connecting pipe 235 is connected to an air pump. The air pump can adjust the internal pressure of the elastic airbag 233 according to the wind speed of the air knife 25: when the wind speed of the air knife 25 is high, the internal pressure of the elastic airbag 233 is increased; when the wind speed of the air knife 25 is low, the internal pressure of the elastic airbag 233 is decreased.

[0057] An internal pressure regulating valve 236 is provided between the connecting pipe 235 and the air pump, which can regulate the gas flow through the pressure difference between the inside and outside of the elastic airbag 233.

[0058] The internal pressure regulating valve 236 includes a pressure regulating pipe 2361, one end of which is connected to an air pump, and the other end of which is connected to a connecting pipe 235. A conical valve body 2362 is provided inside the pressure regulating pipe 2361. The diameter of the opening at the end of the conical valve body 2362 near the air pump is smaller than the diameter of the opening at the end near the connecting pipe 235. A blocking ball 2364 is provided inside the conical valve body 2362, which can block the opening at the end of the conical valve body 2362 near the air pump. A first elastic adjusting member 2363 is provided between the blocking ball 2364 and the conical valve body 2362. A supporting inclined surface 2366 is fixed at the end of the conical valve body 2362 near the connecting pipe 235. A second elastic adjusting member 2365 is provided between the supporting inclined surface 2366 and the blocking ball 2364.

[0059] A friction pad 234 is provided between the elastic airbag 233 and the support rod 231. The friction pad 234 is fixed to the elastic airbag 233 and contacts the support rod 231.

[0060] The outer tube 232 is provided with a plug 237 at its port, and the plug 237 is fixed to the outer tube 232;

[0061] The support rod 231 is provided with an inner insertion rod 239. One end of the inner insertion rod 239 is inserted into the support rod 231, and the other end is fixed to the outer tube 232. A plurality of triangular supports 238 are provided between the inner insertion rod 239 and the inner wall of the outer tube 232. The triangular supports 238 are fixed to the inner insertion rod 239 and the inner wall of the outer tube 232.

[0062] The stabilizing extension rod 23 is provided with a stabilizing floating support 24, which can slide or be fixed along the stabilizing extension rod 23.

[0063] The air knife 25 is mounted on the stable floating support 24.

[0064] In this embodiment, the air force of the air knife 25 can be increased or decreased as needed. When the air speed of the air knife 25 is increased, due to the limited space of the outer casing, components such as the chassis 3 and guide rod 21 are prone to violent shaking under the action of the air knife 25. This shaking can cause the air knife 25 to vibrate, which not only affects the control of the air knife 25's position but also risks causing local damage to the outer casing. The purpose of this application is only to blow the outer casing, so it is necessary to eliminate the risk of the air knife 25 impacting the outer casing to the maximum extent. Therefore, it is necessary to control the amplitude of the air knife 25 while avoiding fatigue of the support rod 231. In this application, the support rod 231 is used to connect with the guide rod 21, so the air knife 25's... The vibration is transmitted most directly through the outer sleeve 232 to the support rod 231. The elastic airbag 233 forms a buffer between the support rod 231 and the outer sleeve 232. Depending on the wind speed of the air knife 25, if the wind speed of the air knife 25 is high, the vibration will definitely intensify. At this time, the support of the elastic airbag 233 needs to be relatively stiff. Therefore, pressure can be added to the elastic airbag 233 to improve its support capacity. If the wind speed of the air knife 25 is low, the vibration is reduced. At this time, it is even more necessary to maintain the stability and safety of the support rod 231. Therefore, the internal pressure of the elastic airbag 233 can be reduced to make its support relatively soft, thereby improving the buffering capacity of the elastic airbag 233. This can effectively protect the support rod 231.

[0065] In this embodiment, the pressure regulating pipe 2361 is used to withstand pressure changes at both ends, and the strength of the material used should be higher than that of the connecting pipe 235 and the connection end of the air pump. The conical valve body 2362 is beneficial for the sealing ball 2364 to block the channel. The supporting inclined surface 2366 is used to provide fixed support for the second elastic adjusting member 2365.

[0066] In this embodiment, the sealing ball 2364 controls the internal pressure through the combined action of the first elastic adjusting member 2363 and the second elastic adjusting member 2365. The elastic support force of the first elastic adjusting member 2363 and the second elastic adjusting member 2365 can be adjusted to adapt to different needs. In this embodiment, the first elastic adjusting member 2363 and the second elastic adjusting member 2365 can be implemented by springs, tension ropes or other elastic components. Without affecting the ventilation in the pressure regulating pipe 2361, the pressure dynamic balance at the sealing ball 2364 can be achieved, so that the sealing ball 2364 can seal the conical valve body 2362 when needed, thereby protecting the elastic airbag 233 from bursting or preventing the elastic airbag 233 from having too soft a support force.

[0067] A solenoid valve 1 is provided on the chassis 3, and the solenoid valve 1 is connected to the inside of the chassis 3.

[0068] The bottom of the chassis 3 is provided with a water receiving tank 4, which is connected to the chassis 3, and the bottom of the water receiving tank 4 is provided with a water inlet 5.

[0069] In this embodiment, the solenoid valve 1 is used to connect the inside and outside of the housing 3, so that the pressure inside the housing 3 is kept balanced. The water tank 4 can receive impurities, including moisture, that fall from the surface of the housing during the purging process. The water inlet 5 can drain the water in the water tank 4 in a timely manner to prevent it from becoming full.

[0070] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
