Description

Technical Field

[0001] The utility model relates to the technical field of infrared welding, in particular to a rotating air supply structure. Background Art

[0002] In the technical field of infrared welding, the product clamping mechanism is a key component to ensure welding quality and working efficiency. In the current market, for clamping mechanisms that require both rotation and ventilation functions simultaneously, several key challenges are generally faced. The primary problem lies in the insufficient ventilation stability. Due to the continuous rotational movement of the follower cylinder, its inlet and outlet pipes are often inevitably entangled, which not only limits the movement range of the cylinder but also easily leads to blocked or interrupted gas flow, thereby directly weakening the effectiveness and stability of the clamping mechanism and posing a potential threat to the accuracy and quality of the welding operation.

[0003] Secondly, to overcome the ventilation problem, some manufacturers have adopted complex transmission systems and sealing designs. Although these designs have alleviated the ventilation problem to a certain extent, they have also brought about a significant increase in manufacturing costs and complexity in maintenance. The complex structure not only increases the cost of initial investment but also prolongs the time for troubleshooting and repair, reducing the overall operating efficiency of the equipment.

[0004] Furthermore, although electric clamping mechanisms have shown advantages in solving ventilation problems, they often struggle to fully meet the high-precision requirements such as control accuracy and response speed in infrared welding. Compared with pneumatic clamping mechanisms, electric mechanisms may be slightly inferior in terms of response speed, and in high-cleanliness environments, the maintenance and cleaning of electric components are more cumbersome, which may affect the overall cleanliness of the production line and the final quality of the product.

[0005] In summary, the existing clamping mechanisms in the market have deficiencies in multiple aspects such as ventilation stability, structural complexity, and control convenience when balancing rotation and ventilation functions, and there is an urgent need for a more innovative, efficient, and economical solution to improve the situation. Summary of the Invention

[0006] The purpose of the utility model is to provide a rotating air supply structure to solve the problems raised in the above background art.

[0007] To solve the above technical problems, the utility model provides the following technical solutions:

[0008] The described rotary air supply structure includes a cover, a retaining disc, a driving wheel, an air intake adapter plate, a rotating disc, a sealing ring, and a rotating shaft. The cover is fixedly connected to the retaining disc. One end of the rotating shaft is rotatably connected to the retaining disc, and the other end is connected to the rotating disc. The driving wheel is fixedly installed at one end of the outer surface of the rotating shaft near the retaining disc. The air intake adapter plate is fixedly installed at one end of the outer surface of the rotating shaft away from the retaining disc. The air intake adapter plate consists of a flat portion and a protruding portion. The rotating disc is provided with a cylindrical groove, and the protruding portion of the air intake adapter plate is snap-fitted into the groove of the rotating disc for fixed connection. The rotating disc is fixedly connected to the rotating shaft, and the sealing ring is sleeved on the outer surface of the protruding portion of the air intake adapter plate.

[0009] The cover and the retaining disc are used to limit the axial movement of the rotating disc. The driving wheel is used for power transmission. The air intake adapter plate is used for the delivery of gas from an external cylinder. The rotating disc is used for clamping the product. The sealing ring is used to ensure that the two sets of air paths can provide air pressure simultaneously during rotation while the air intake adapter plate and the rotating disc are rotating, and they do not affect each other. The rotating shaft is used for power transmission and at the same time limits the axial movement of the rotating disc. When an external motor drives the driving wheel to rotate through a synchronous belt, the rotating disc and the air intake adapter plate are driven to rotate synchronously under the transmission of the rotating shaft. The controller controls the air pump to supply air into the air intake adapter plate, and the gas flows out from the rotating disc through the sealing ring, thereby providing air pressure for the rotating rotating disc, ensuring that air pressure is continuously provided while the rotating disc is rotating, and the two sets of air paths do not affect each other, providing a prerequisite for the welding quality of the product, and at the same time ensuring the stability of airtightness.

[0010] Further, the protruding portion of the cover is snap-fitted into the inner ring of the retaining disc.

[0011] The snap-fitting design of the protruding portion of the cover and the inner ring of the retaining disc facilitates the disassembly and assembly of the cover and the retaining disc while ensuring a tight connection between the two, avoiding vibrations and noises caused by loosening or gaps. This integrated or tightly connected structure enhances the integrity of the entire assembly, making it more stable and reliable during operation.

[0012] Further, a cavity is provided inside the air intake adapter plate, an air intake hole is provided on the side surface of the flat portion of the air intake adapter plate, and an air outlet hole is provided on the side surface of the rotating disc.

[0013] To enable the two sets of air paths to provide air pressure simultaneously during the rotation of the rotating disc without affecting each other.

[0014] Further, there are 3 sealing rings.

[0015] The three-ring design provides multiple sealing barriers for the gas path. Each sealing ring plays an independent and complementary sealing role. This multiple protection mechanism can significantly reduce the risk of gas leakage and ensure that the gas pressure between the two groups of gas paths is effectively isolated. Even during rotation, they will not interfere or affect each other, and can maintain the stability of their respective air pressures.

[0016] Furthermore, a circular plate is provided at the contact end between the rotating shaft and the turntable.

[0017] The circular plate design can effectively limit the axial movement of the turntable during rotation, ensuring a smoother and more controllable motion trajectory. This stability is crucial for the normal operation of precision machinery or equipment, while also preventing severe axial runout from causing damage or failure of transmission components.

[0018] Furthermore, four rectangular grooves are evenly arranged on the surface of the turntable.

[0019] The four rectangular grooves are evenly distributed on the surface of the turntable, so that the clamping mechanism of the welding device below can be evenly stressed during connection, avoiding the unstable clamping phenomenon caused by excessive force at a single point or local area. The design of the rectangular grooves can increase the rigidity of the turntable surface, making the clamping mechanism more stable when clamping the product and less likely to shift or deform.

[0020] Furthermore, the moving wheel is key-connected to the rotating shaft.

[0021] The key connection enables the driven wheel to be axially fixed and effectively transmit torque. The key connection also ensures the stability of the axial position of the driven wheel on the rotating shaft, preventing it from axial sliding or offset during operation.

[0022] Compared with the existing technology, the beneficial effect achieved by the utility model is: the utility model maintains the external air source intake and continuous air supply to the turntable by adding a sealing ring to the protruding part of the air intake adapter plate, ensuring that the turntable continuously provides air pressure while rotating, and the two sets of air circuits do not affect each other, providing the prerequisite for the welding quality of the product, while ensuring the stability of the air tightness.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] The present utility model provides a technical solution:

[0034] As Figure 1 , 2 , 4 shows, a rotary gas supply structure includes a cover 1, a retaining disc 2, a driving wheel 3, an air inlet adapter plate 4, a turntable 5, a sealing ring 6 and a rotating shaft 7. The cover 1 is fixedly connected to the retaining disc 2. One end of the rotating shaft 7 is rotatably connected to the retaining disc 2, and the other end is connected to the turntable 5. The driving wheel 3 is fixedly installed at one end of the outer surface of the rotating shaft 7 close to the retaining disc 2. The air inlet adapter plate 4 is fixedly installed at one end of the outer surface of the rotating shaft 7 away from the retaining disc 2. The air inlet adapter plate 4 is composed of a flat part and a convex part. The turntable 5 is provided with a cylindrical groove. The convex part of the air inlet adapter plate 4 is clamped in the groove of the turntable 5 and fixedly connected. The turntable 5 is fixedly connected to the rotating shaft 7. The sealing ring 6 is sleeved on the outer surface of the convex part of the air inlet adapter plate 4.

[0035] The cover 1 and the retaining disc 2 are used to limit the axial movement of the turntable 5. The driving wheel 3 is used for power transmission. The air intake adapter plate 4 is used for the delivery of gas from an external cylinder. The turntable 5 is used for clamping the product. The sealing ring 6 is used to ensure that the two groups of air circuits can provide air pressure simultaneously during rotation between the air intake adapter plate 4 and the turntable 5 without affecting each other. The rotating shaft 7 is used for power transmission and also limits the axial movement of the turntable 5. When an external motor drives the driving wheel 3 to rotate through a synchronous belt, the turntable 5 and the air intake adapter plate 4 are driven to rotate synchronously under the transmission of the rotating shaft 7. The controller controls the air pump to supply air into the air intake adapter plate 4, and the gas flows out from the turntable 5 through the sealing ring 6, thereby providing air pressure for the rotating turntable 5, ensuring that air pressure is continuously provided while the turntable 5 is rotating, and the two air circuits do not affect each other, providing a prerequisite for the welding quality of the product and ensuring the stability of airtightness at the same time.

[0036] As Figure 4 shown, the protruding part of the cover 1 is snap-fitted into the inner ring of the retaining disc 2.

[0037] The snap-fitting design of the protruding part of the cover 1 and the inner ring of the retaining disc 2 facilitates the disassembly and assembly of the cover 1 and the retaining disc 2 while ensuring a tight connection between the two, avoiding vibration and noise caused by loosening or gaps. This integrated or tightly connected structure enhances the integrity of the entire assembly, making it more stable and reliable during operation.

[0038] As Figure 4 、 5 、6 shown, the air intake adapter plate 4 is internally provided with a cavity, an air intake hole is provided on the side of the flat part of the air intake adapter plate 4, and an air outlet hole is provided on the side of the turntable 5.

[0039] In order to enable the turntable 5 to maintain the ability to provide air pressure for the two groups of air circuits simultaneously during rotation without affecting each other.

[0040] As Figure 5 shown, there are 3 sealing rings 6.

[0041] The design of the 3 sealing rings 6 provides multiple sealing barriers for the air circuit. Each sealing ring 6 plays an independent and complementary sealing role. This multiple safeguard mechanism can significantly reduce the risk of gas leakage, ensure that the gas pressure between the two groups of air circuits is effectively isolated, and will not interfere or affect each other even during rotation, and can maintain the air pressure stability of each.

[0042] As Figure 7 shown, a circular plate is provided at the contact end of the rotating shaft 7 and the turntable 5.

[0043] The design of the circular plate can effectively limit the axial movement of the turntable 5 during rotation, ensuring that the movement trajectory of the turntable 5 is smoother and more controllable. This stability is crucial for the normal operation of precision machinery or equipment, while avoiding severe axial runout that may cause damage or failure of transmission components.

[0044] like Figure 3 As shown, four rectangular grooves are evenly arranged on the surface of the turntable 5.

[0045] The four rectangular grooves are evenly distributed on the surface of the turntable 5, so that the clamping mechanism below can be evenly stressed during connection, avoiding the clamping instability caused by excessive force at a single point or local area. The design of the rectangular grooves can increase the rigidity of the surface of the turntable 5, making the clamping mechanism of the welding device more stable when clamping the product and less prone to displacement or deformation.

[0046] like Figure 2 As shown, the driving wheel 3 is key-connected to the rotating shaft 7 .

[0047] The key connection enables the moving wheel 3 to be axially fixed and effectively transmit torque. The key connection can also ensure that the axial position of the moving wheel 3 on the rotating shaft 7 is stable, preventing it from axial sliding or deviation during operation.

[0048] The working principle of this utility model:

[0049] When the external motor drives the driving wheel 3 to rotate through the synchronous belt, the turntable 5 and the air intake adapter plate 4 are driven to rotate synchronously under the transmission action of the rotating shaft 7. The controller controls the air pump to ventilate the inside of the air intake adapter plate 4, and the gas flows out from the turntable 5 through the sealing ring 6, thereby providing air pressure for the rotating turntable 5, ensuring that the turntable 5 continues to provide air pressure while rotating, and the two sets of air paths do not affect each other, providing the prerequisite for the welding quality of the product, while ensuring the stability of the air tightness.
