Description

Technical Field

[0001] This utility model relates to the field of air knife technology, specifically to a slanted air knife. Background Technology

[0002] Air knives have numerous applications in industrial fields, including blowing away moisture and dust. For example, they can remove dust and moisture from flat surfaces such as steel plates and aluminum alloy profiles; remove moisture from the surfaces of beverage bottles and cans; remove impurities, dust, residual liquid, and moisture from product surfaces and packaging; and clean conveyor belts. With a compressed air supply, air knives can perfectly meet these applications.

[0003] Traditional air knives are mostly one-piece designs, which easily accumulate dust and impurities inside, making them difficult to clean. After long-term use, the air outlet is prone to blockage, affecting service life and work efficiency. In addition, their vertical air outlet direction results in low utilization of high-pressure air and uneven airflow distribution, which limits the effectiveness in drying, cleaning and other scenarios. Therefore, a slanted air knife is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a slanted air knife to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slanted air knife, comprising an air knife body, a first clamping plate and a second clamping plate respectively provided on the top of the air knife body, a sliding groove provided inside the air knife body, a flow divider plate inserted inside the sliding groove, a plurality of flow divider ports opened on one side of the flow divider plate, a plurality of connecting screws connected between the first clamping plate and the second clamping plate by thread, a first cover plate and a second cover plate respectively installed at both ends of the air knife body, an air inlet opened on one side of the first cover plate, an air outlet provided between the first clamping plate and the second clamping plate, and a limit component provided on one side of the second clamping plate.

[0006] Preferably, both ends of the air knife body are provided with several protrusions, and the interior of the several protrusions is provided with a first internal thread hole.

[0007] Preferably, each of the first and second cover plates has a plurality of through holes on one side, and a connecting bolt passes through the interior of each of the plurality of through holes. One end of the connecting bolt is threaded into the interior of the first internal thread hole.

[0008] Preferably, silicone gaskets are provided between the first and second cover plates and both ends of the air knife body.

[0009] Preferably, a second internal threaded hole is provided on one side of the second cover plate, which is used for the installation of a fixed threaded component.

[0010] Preferably, the aforementioned limiting assembly includes several fixing plates, several fixing bolts, and several limiting posts. The fixing plates are respectively fixedly connected to one side of the second clamping plate and located above several connecting screws. The fixing bolts are respectively threaded to the fixing plates. The limiting posts are rotatably connected to one end of the fixing bolts. The bottom of each limiting post is provided with an arc-shaped groove, and the inner side of the arc-shaped groove is provided with a first anti-slip texture.

[0011] Preferably, one end of each of the aforementioned connecting screws is fixedly connected to a fixing post, the outer side of the fixing post is provided with a second anti-slip texture, and the inner side of the arc-shaped groove abuts against the outer side of the fixing post.

[0012] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0013] 1. This utility model utilizes a tool to rotate a connecting screw, which in turn moves the second clamping plate closer to or further away, thereby adjusting the distance between the first and second clamping plates to facilitate the use of the air knife body. The air outlet formed by the first and second clamping plates has an obliquely cut inner wall at a 15° angle, which improves the entrainment effect of air within the air knife body cavity, providing a stable, continuous, and high-flow-rate air supply. Furthermore, the design of the diverter plate and diverter port evenly distributes airflow, stabilizes airflow pressure, saves energy, reduces ineffective airflow loss, avoids energy waste, and improves the efficiency and performance of the air knife body.

[0014] 2. This utility model uses a forward-rotating fixing bolt to drive the arc-shaped groove on the limiting post to abut against the outside of the fixing post. At the same time, the first anti-slip texture on the arc-shaped groove abuts against the second anti-slip texture on the outside of the fixing post. This can effectively limit the fixing post and prevent the connecting screw from rotating under external force, thereby affecting the normal use of the air knife body.

[0015] 3. This utility model allows for the cleaning of the inside of the air knife body by removing the connecting bolts on the first and second cover plates, removing the silicone gaskets from both ends of the air knife body, and then pulling the diverter plate out from the inside of the slide groove. This extends the service life of the air knife body, prevents the air outlet from becoming blocked, and improves work efficiency. Attached Figure Description

[0025] Example 1

[0026] Please see Figure 1-4This utility model provides a technical solution: a slanted air knife, including an air knife body 1, a first clamping plate 2 and a second clamping plate 3 respectively provided on the top of the air knife body 1, a sliding groove 7 provided inside the air knife body 1, a flow divider 8 inserted inside the sliding groove 7, and a plurality of flow divider ports 9 opened on one side of the flow divider 8. Through the setting of the flow divider 8 and the flow divider ports 9, the airflow is evenly distributed and the airflow pressure is stabilized, and energy is saved and consumption is reduced to reduce the loss of ineffective airflow, avoid energy waste, and improve the efficiency and performance of the air knife body 1.

[0027] Several connecting screws 6 are threadedly connected between the first clamping plate 2 and the second clamping plate 3. A first cover plate 10 and a second cover plate 11 are respectively installed at both ends of the air knife body 1. An air inlet 13 is provided on one side of the first cover plate 10. An air source blower or high-pressure blower is connected to the air inlet 13, and air is introduced into the interior of the air knife body 1 through the air inlet 13. An air outlet 15 is provided between the first clamping plate 2 and the second clamping plate 3. By rotating the connecting screws 6 with a tool, the connecting screws 6 move the second clamping plate 3 closer or further away, thereby adjusting the distance between the first clamping plate 2 and the second clamping plate 3 to facilitate the use of the air knife body 1. The air outlet 15 formed by the first clamping plate 2 and the second clamping plate 3 has an inner wall with a 15° beveled structure, which improves the entrainment effect of air within the air knife body cavity, thus providing stable, continuous, and high-flow-rate air. A limit component is provided on one side of the second clamping plate 3.

[0028] The blade of the second clamping plate 3 utilizes the Coanda effect to guide air to adhere to the surface of the blade. This maintains the integrity of the airflow all the way downstream and creates an environment for entraining surrounding air, ultimately increasing the total air volume. As a result, a balanced, high-flow, and continuous airflow is guaranteed throughout the air knife blade.

[0029] To facilitate cleaning of the air knife body 1, several protrusions 4 are provided at both ends of the air knife body 1. The interior of each protrusion 4 is provided with a first internal threaded hole 5. Several through holes 12 are provided on one side of the first cover plate 10 and the second cover plate 11. A connecting bolt passes through the interior of each through hole 12. One end of the connecting bolt is threaded into the interior of the first internal threaded hole 5. By removing the connecting bolts on the first cover plate 10 and the second cover plate 11 and removing the silicone gasket from both ends of the air knife body 1, the diverter plate 8 can be pulled out from the interior of the slide groove 7. This facilitates cleaning of the interior of the air knife body 1, extends the service life of the air knife body 1, prevents the air outlet 15 from becoming blocked, and improves work efficiency.

[0030] Silicone gaskets are provided between the first cover plate 10 and the second cover plate 11 and both ends of the air knife body 1. The silicone gaskets can ensure the sealing when the first cover plate 10 and the second cover plate 11 are fixed. A second internal threaded hole 14 is provided on one side of the second cover plate 11. The second internal threaded hole 14 is used for the installation of fixed threaded parts. The second internal threaded hole 14 can facilitate the installation of the air knife body 1 on the production equipment. This is the prior art and will not be described in detail here.

[0031] The working principle or structural principle is as follows: when it is necessary to adjust the distance between the first clamping plate 2 and the second clamping plate 3, the connecting screw 6 is rotated by a tool. The connecting screw 6 drives the second clamping plate 3 to move closer or further away, thereby adjusting the distance between the first clamping plate 2 and the second clamping plate 3 to facilitate the use of the air knife body 1. The air outlet 15 formed by the first clamping plate 2 and the second clamping plate 3 has an oblique cut structure with a 15° oblique cut angle, which can improve the entrainment effect of air in the inner wall of the air knife body cavity, thereby providing stable, continuous, and large-flow air. Moreover, through the setting of the diverter plate 8 and the diverter port 9, the airflow is evenly distributed and the airflow pressure is stabilized, which also saves energy and reduces ineffective airflow loss, avoids energy waste, and improves the efficiency and performance of the air knife body 1.

[0032] When it is necessary to clean the air knife body 1, the connecting bolts on the first cover plate 10 and the second cover plate 11 are removed, and the silicone gaskets are removed from both ends of the air knife body 1. At this time, the diverter plate 8 can be pulled out from the inside of the slide groove 7, which facilitates the cleaning of the inside of the air knife body 1, extends the service life of the air knife body 1, prevents the air outlet 15 from being blocked, and improves work efficiency.

[0033] Example 2

[0034] Please see Figure 5 Unlike Embodiment 1, the limiting assembly includes several fixing plates 16, several fixing bolts 17, and several limiting posts 18. The fixing plates 16 are respectively fixedly connected to one side of the second clamping plate 3 and located above several connecting screws 6. The fixing bolts 17 are respectively threaded to the fixing plates 16. The limiting posts 18 are rotatably connected to one end of the fixing bolts 17. The bottom of each limiting post 18 is provided with an arc-shaped groove 19. By rotating the fixing bolts 17 in the forward direction, the fixing bolts 17 move on the fixing plates 16 and drive the arc-shaped grooves 19 on the limiting posts 18 to abut against the outside of the fixing posts 20, preventing the connecting screws 6 from rotating under external force, thereby affecting the normal use of the air knife body 1.

[0035] The inner side of the arc-shaped groove 19 is provided with a first anti-slip texture; one end of each of the several connecting screws 6 is fixedly connected to a fixing post 20, and the outer side of the fixing post 20 is provided with a second anti-slip texture. The inner side of the arc-shaped groove 19 abuts against the outer side of the fixing post 20. Through the provision of the first anti-slip texture on the arc-shaped groove 19 and the second anti-slip texture on the outer side of the fixing post 20, the arc-shaped groove 19 can effectively limit the fixing post 20.

[0036] Working principle or structural principle: After the first clamping plate 2 and the second clamping plate 3 are adjusted by the connecting screw 6, the fixing bolt 17 is rotated in the forward direction. The fixing bolt 17 moves on the fixing plate 16 and drives the arc-shaped groove 19 on the limiting post 18 to abut against the outside of the fixing post 20. Through the setting of the first anti-slip texture on the arc-shaped groove 19 and the second anti-slip texture on the outside of the fixing post 20, the arc-shaped groove 19 can effectively limit the fixing post 20, preventing the connecting screw 6 from rotating under external force, thereby affecting the normal use of the air knife body 1.
