DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-6 As shown, an air flow driving device of a silicone knitting machine includes a fixing base 1 and a blowing component 4; the blowing component 4 is connected to the fixing base 1 through a hole;

[0028] The blowing assembly 4 consists of a No. 1 through pipe 41, a No. 2 through pipe 44, a connecting plate 42 and a connecting pipe 45; the No. 1 through pipe 41 is connected to one end of the connecting plate 42 through a hole; the No. 2 through pipe 44 is connected to the connecting pipe 45; a limiting plate 43 is fixedly connected to the bottom surface of one end of the connecting pipe 45; the other end of the connecting plate 42 is fixedly connected to the limiting plate 43; evenly spaced air holes 451 are provided on the top surface of the connecting pipe 45; a No. 3 cavity 452 is provided inside the connecting pipe 45; the No. 2 through pipe 44 is connected to the No. 3 cavity 452; the air holes 451 are connected to the No. 3 cavity 452.

[0029] When the air blowing assembly 4 is working, the No. 1 through-tube 41 is connected to the air pipe, and a hose is connected between the No. 2 through-tube 44 and the No. 1 through-tube 41, so that the No. 1 through-tube 41 and the No. 2 through-tube 44 are connected to each other during operation, and the connection between the No. 1 through-tube 41 and the connecting tube 45 is indirectly realized. The No. 1 through-tube 41 is connected to the air pipe. When the air blowing assembly 4 is working, the air flows through the No. 1 through-tube 41, enters the connecting tube 45 through the No. 2 through-tube 44, and is discharged through the air holes 451 evenly spaced in the connecting tube 45, thereby supporting the upper silicone tube body 3, thereby On the basis of the principles of fluid mechanics and Coanda theory, when the gas is blown toward the surface of the silicone tube body 3, the gas will move along the surface of the silicone tube body 3, wrap the silicone tube body 3, and make the silicone tube body 3 suspended and reach balance at the center of the blowing, so that the silicone tube body 3 can smoothly pass through the No. 1 through hole 13 and be knitted, wherein the blowing component 4 is fixed to the limiting seat 21 of the sleeve 2 by the limiting plate 43, so as to fix the blowing component 4, and by fixing the connecting plate 42 on one side of the limiting plate 43, it is used to fix the No. 1 through tube 41.

[0030] As an embodiment of the present invention, an operating groove 12 is opened inside the fixing seat 1; symmetrical through holes 13 are opened on the side walls at both ends of the operating groove 12; a sleeve 2 is connected through the through hole 13 on the right side of the fixing seat 1; the blowing component 4 is arranged in the sleeve 2; a cavity 221 is arranged inside the sleeve 2; the blowing component 4 is arranged in the cavity 221.

[0031] During operation, the operating groove 12 is the position where the silicone tube body 3 is knitted, and the No. 1 through hole 13 on both sides of the fixed seat 1 is used for the passage of the unknitted silicone tube body 3 and the passage of the knitted silicone tube body 3, wherein the sleeve 2 is arranged in the No. 1 through hole 13 on one side of the fixed seat 1, and the two sides of the sleeve 2 are through structures, so that during actual operation, the movement of the silicone tube body 3 will not be affected.

[0032] As an embodiment of the present invention, the sleeve 2 is composed of a limit seat 21 and a cylinder shell 22; the limit seat 21 is fixedly connected to one end of the cylinder shell 22; the limit seat 21 is fixedly connected to the outer wall of the fixed seat 1; a No. 1 cavity 221 is opened inside the cylinder shell 22; a No. 2 through hole 222 is opened on the side wall of the end of the cylinder shell 22 away from the limit seat 21; the No. 2 through hole 222 is connected to the No. 1 cavity 221.

[0033] During operation, the No. 1 cavity 221 inside the sleeve 2 can be filled with gas when the blowing component 4 blows air. Since the structure of the sleeve 2 is a cylindrical structure, after the airflow fills the interior, it will support the silicone tube body 3 and further support the silicone tube body 3 along the inner wall of the No. 1 cavity 221, thereby enhancing the supporting effect of the airflow on the silicone tube body 3 and preventing the hot-melt silicone tube body 3 from deforming during the movement and adhering to the position of the knitting machine head, wherein the No. 2 through hole 222 at the front end of the sleeve 2 corresponds to the position of the knitting machine head.

[0034] As an embodiment of the present invention, a plurality of symmetrically arranged adjustment grooves 223 are provided on the outer wall of one end of the cylinder shell 22 away from the limiting seat 21; two groups of buckle grooves 224 are provided inside the adjustment grooves 223; and an adjustment part 23 is slidably connected inside a plurality of the adjustment grooves 223.

[0035] During operation, the adjusting portion 23 can slide in the adjusting groove 223 to adjust the opening size of the No. 2 through hole 222 at the front end of the sleeve 2. Therefore, when the silicone tube body 3 has different inner diameters, the size of the No. 2 through hole 222 at the front end of the sleeve 2 can be indirectly changed by adjusting the adjusting portion 23. This avoids the gas leaking through the No. 2 through hole 222 when the blowing assembly 4 is blowing, causing the air pressure inside the sleeve 2 to decrease, affecting the airflow supporting the silicone tube, causing the silicone tube body 3 to deform and adhere to the device, further resulting in the subsequent silicone tube being unable to pass through.

[0036] As an embodiment of the present invention, a handle 231 is fixedly connected to the surface of the adjusting portion 23 ; a second cavity 232 is opened inside the adjusting portion 23 ; a spring buckle 233 is provided in the second cavity 232 ; and the spring buckle 233 is snapped into the buckle groove 224 .

[0037] During operation, when it is necessary to adjust the No. 2 through hole 222 at the front end of the sleeve 2, the handle 231 is held by human hand to drive the adjusting part 23 to slide in the adjusting groove 223. During the movement of the adjusting part 23, the spring buckle 233 inside it will be squeezed by the bottom surface of the adjusting groove 223 and shrink in the No. 2 cavity 232. As the adjusting part 23 moves to the corresponding position of another set of buckle grooves 224, the spring buckle 233 is buckled downward and connected in the buckle groove 224, thereby realizing the adjustment of the size of the No. 2 through hole 222 by the adjusting part 23.

[0038] As an embodiment of the present invention, the internal perforation of the sleeve 2 is connected to a silicone tube body 3; the silicone tube body 3 is arranged above the blowing assembly 4; the middle perforation of the silicone tube body 3 is connected to the No. 2 through hole 222; the front end perforation of the silicone tube body 3 is connected to the No. 1 through hole 13.

[0039] During operation, the silicone tube moves from right to left inside the sleeve 2 and is supported by the blowing assembly 4, so that it can be suspended under the drive of the airflow and keep balance in the center of the sleeve 2, so that it can smoothly pass through the No. 2 through hole 222 and be knitted along its path from right to left.

[0040] As an embodiment of the present invention, the limit plate 43 is fixedly connected to the outer side of the limit seat 21; the No. 1 through pipe 41 is arranged on the outer side of the limit plate 43; and the structure of the connecting plate 42 is L-shaped.

[0041] As an embodiment of the present invention, the moving speed of the silicone tube is 3-20 m / min; the compressed air pressure in the No. 1 through pipe 41 and the No. 2 through pipe 44 is 0.1-0.2 Mpa, and the air consumption is 3.33 m³ / h.

[0042] Working principle: when working, the silicone tube moves from right to left inside the sleeve 2, and is supported by the blowing assembly 4, so that it can be driven by the airflow to produce a suspended state and keep balance in the center of the sleeve 2, so that it can smoothly pass through the No. 2 through hole 222 and knit as it moves from right to left. Specifically, when the blowing assembly 4 is working, the No. 1 through pipe 41 is connected to the air pipe, and a hose is connected between the No. 2 through pipe 44 and the No. 1 through pipe 41, so that when working, the No. 1 through pipe 41 and the No. 2 through pipe 44 are kept in a connected state, indirectly realizing the No. 1 through pipe 4 1 is connected to the connecting pipe 45, and the No. 1 connecting pipe 41 is connected to the air pipe. When working, the air flows through the No. 1 connecting pipe 41, enters the connecting pipe 45 through the No. 2 connecting pipe 44, and is discharged through the air holes 451 arranged at uniform intervals in the connecting pipe 45, thereby achieving a supporting effect on the upper silicone tube body 3. Therefore, based on the principles of fluid mechanics and Coanda theory, when the gas is blown to the surface of the silicone tube body 3, the gas will move along the surface of the silicone tube body 3, wrap the silicone tube body 3, make the silicone tube body 3 suspended and reach equilibrium at the center of the blowing, so that the silicone tube body 3 The hose body 3 can smoothly pass through the No. 1 through hole 13 and be knitted, wherein the blowing assembly 4 is fixed on the limiting seat 21 of the sleeve 2 by the limiting plate 43, so as to realize the fixing effect on the blowing assembly 4, and the connecting plate 42 is fixed on one side of the limiting plate 43 to fix the No. 1 through pipe 41, and when the size of the No. 2 through hole 222 needs to be adjusted, the adjusting part 23 is driven to slide in the adjusting groove 223 by the human hand holding the handle 231, wherein during the movement of the adjusting part 23, the spring buckle 233 inside it will be squeezed by the bottom surface of the adjusting groove 223 and shrink in the No. 2 cavity 2 32, as the adjusting portion 23 moves to the corresponding position of another set of buckle grooves 224, the spring buckle 233 is buckled downward and connected in the buckle groove 224, so that the size of the No. 2 through hole 222 is adjusted by the adjusting portion 23. By adjusting the adjusting portion 23, the size of the No. 2 through hole 222 at the front end of the sleeve 2 is indirectly changed, thereby avoiding that when the blowing component 4 blows, the gas leaks through the No. 2 through hole 222, causing the air pressure inside the sleeve 2 to decrease, affecting the airflow supporting the silicone tube, causing the silicone tube body 3 to be deformed and adhere to the device, further resulting in the subsequent silicone tube being unable to pass.
