Description

Technical Field

[0001] The utility model belongs to the technical field of chemical fiber production, and particularly relates to an air volume regulating device for chemical fiber equipment. Background Technique

[0002] Chemical fiber equipment is an indispensable machine in the process of chemical fiber production. It has various types, including spinning equipment, drawing and texturing equipment, deep processing plant equipment, etc. The air volume regulating device for chemical fiber equipment is a key device for controlling the side blowing air volume in the process of chemical fiber production, which directly affects the quality and production efficiency of chemical fiber filaments.

[0003] Most of the existing air volume regulating devices for chemical fiber equipment are manually adjusted according to experience, resulting in low adjustment efficiency, increased waste silk rate, and the air volume regulation does not have the function of decelerating the wind force, resulting in too large blowing wind force, affecting the filament forming effect of chemical fiber and causing greater economic losses. Therefore, we propose an air volume regulating device for chemical fiber equipment. Content of the Utility Model

[0004] The purpose of the utility model is to provide an air volume regulating device for chemical fiber equipment. By setting an air volume regulating component, specifically starting the electric push rod 1 to drive the push block to move left or right, the rack and gear rotate counterclockwise or clockwise, and then the adjusting fan blades rotate counterclockwise or clockwise, so as to control the gap size between the two adjusting fan blades to control the air volume. After the adjusting fan blades rotate, they are in an inclined state. Therefore, the wind force will be decelerated after passing through the adjusting fan blades, thus achieving the effect of speed reduction, improving the adjustment efficiency, eliminating the need for manual adjustment, improving the filament forming effect of chemical fiber, reducing the situation of waste silk, and solving the problems that most of the existing air volume regulating devices are manually adjusted according to experience, resulting in low adjustment efficiency, increased waste silk rate, and the air volume regulation does not have the function of decelerating the wind force, resulting in too large blowing wind force, affecting the filament forming effect of chemical fiber.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is an air volume regulating device for chemical fiber equipment, including an air duct. A blocking plate is fixedly connected to the front of the air duct. A shell is fixedly connected to the top of the air duct. An air volume regulating component is arranged on the back of the blocking plate. An air inlet regulating component is arranged on the back of the air duct. A plurality of air inlet notches are opened on the back of the air duct. An electric push rod 1 is fixedly connected to the top of the shell. A push block is fixedly connected to the right output end of the electric push rod 1. A rack is fixedly connected to the bottom of the push block.

[0007] The air volume adjustment component includes a number of adjusting fan blades. A rotating shaft is fixedly connected inside each of the number of adjusting fan blades. The top and bottom of each of the number of rotating shafts are rotatably connected to the air duct. The top of each of the number of rotating shafts penetrates through the air duct and extends to the outside. A gear is fixedly connected to the top of each of the number of rotating shafts. By setting the air volume adjustment component, specifically, starting the first electric push rod drives the push block to move left or right. The rack and gear rotate counterclockwise or clockwise, and then the adjusting fan blades rotate counterclockwise or clockwise, so as to control the gap size between two adjusting fan blades to control the air volume. After the adjusting fan blades rotate, they are in an inclined state. Therefore, the wind will be decelerated after passing through the adjusting fan blades, thus achieving the effect of speed reduction, improving the adjustment efficiency, eliminating the need for manual adjustment, improving the effect of chemical fiber filament formation, and reducing the situation of waste filaments.

[0008] Further, the bottom of the push block penetrates through the housing and extends to the inside. The push block is slidably connected to the housing. The bottom of the rack contacts the top of the air duct. The back of the rack is slidably connected to a limiting track. The bottom of the limiting track is fixedly connected to the top of the air duct. The front of the rack is meshed with the gear. Starting the first electric push rod to drive the push block to move, the rack moves on the limiting track, which can make the movement of the rack more stable and avoid deviation.

[0009] Further, the air inlet adjustment component includes an air inlet pipe. A fixed limiting ring is fixedly connected to the inner wall of the air inlet pipe. A rotating ring is rotatably connected inside the fixed limiting ring. A number of sealing plates are fixedly connected to the inner wall of the rotating ring. The number of sealing plates are arranged in a circumferential array. A fixed block is fixedly connected to the bottom of the rotating ring.

A fixed rod is fixedly connected to the left side of the fixed block. A first connecting block is fixedly connected to the left side of the fixed rod. By setting the air inlet adjustment component, specifically, starting the second electric push rod drives the connecting plate to move up or down. Then the connecting plate moves together with the slider, the vertical rod and the second connecting block. The second connecting block drives the rotating ring to rotate clockwise or counterclockwise on the fixed limiting ring through the fixed shaft, the first connecting block, the fixed rod and the fixed block. By the rotation of the sealing plates, the size of the air inlet notch is adjusted, so as to control the air inlet volume, and the blown air volume can be adjusted again to achieve better air volume control.

A connecting block II is fixedly connected to the bottom of the vertical rod. A fixed shaft is fixedly connected to the back surface of the connecting block II. The back surface of the fixed shaft penetrates through the connecting block I and extends to the outside. Since the slider slides inside the connecting plate and the connecting block I rotates on the fixed shaft, the connecting block I will drive the rotating ring to rotate clockwise or counterclockwise on the fixed limiting ring through the fixed rod and the fixed block.

[0011] Further, the connecting block I is rotatably connected to the fixed shaft. The front surface of the connecting block I contacts the back surface of the connecting block II. The front surfaces of the rotating ring and the sealing plate both contact the back surface of the air duct. The front surface of the air inlet pipe is fixedly connected to the back surface of the air duct.

[0012] The utility model has the following beneficial effects:

[0013] 1. By setting the air volume adjustment component, specifically, starting the electric push rod I to drive the push block to move left or right, the rack and gear rotate counterclockwise or clockwise, and then the adjusting fan blades rotate counterclockwise or clockwise, so as to control the gap size between the two adjusting fan blades to control the air volume. After the adjusting fan blades rotate, they are in an inclined state. Therefore, the wind force will be decelerated after passing through the adjusting fan blades, thus achieving the effect of speed reduction, improving the adjustment efficiency, eliminating the need for manual adjustment, improving the effect of chemical fiber filament formation, and reducing the situation of waste filaments.

[0014] 2. By setting the air inlet adjustment component, specifically, starting the electric push rod II to drive the connecting plate to move up or down, the connecting plate will move together with the slider, the vertical rod and the connecting block II.

An air volume regulating component 13 is arranged on the back of the blocking plate 11. An air inlet regulating component 14 is arranged on the back of the air duct 1. A plurality of air inlet notches 15 are formed on the back of the air duct 1. An electric push rod 121 is fixedly connected to the top of the housing 12. A push block 122 is fixedly connected to the right output end of the electric push rod 121. A rack 123 is fixedly connected to the bottom of the push block 122;

[0027] The air volume regulating component 13 includes a plurality of regulating fan blades 131. A rotating shaft 132 is fixedly connected to the inside of each of the plurality of regulating fan blades 131. The top and bottom of the plurality of rotating shafts 132 are rotatably connected to the air duct 1. The top of the plurality of rotating shafts 132 all penetrate through the air duct 1 and extend to the outside. A gear 133 is fixedly connected to the top of each of the plurality of rotating shafts 132. By setting the air volume regulating component 13, specifically, starting the electric push rod 121 drives the push block 122 to move left or right. The rack 123 and the gear 133 rotate counterclockwise or clockwise, and then the regulating fan blades 131 rotate counterclockwise or clockwise, so as to control the gap size between the two regulating fan blades 131 to control the air volume. After the regulating fan blades 131 rotate, they are in an inclined state. Therefore, the wind force will be decelerated after passing through the regulating fan blades 131, thus achieving the effect of speed reduction, improving the regulation efficiency, eliminating the need for manual adjustment, improving the effect of chemical fiber filament formation, and reducing the situation of waste filaments.

[0028] The bottom of the push block 122 penetrates through the housing 12 and extends to the inside. The push block 122 is slidably connected to the housing 12. The bottom of the rack 123 contacts the top of the air duct 1. A limiting track 124 is slidably connected to the back of the rack 123. The bottom of the limiting track 124 is fixedly connected to the top of the air duct 1. The front of the rack 123 is meshed with the gear 133.

[0029] The air inlet adjusting assembly 14 includes an air inlet pipe 141. A fixed limiting ring 142 is fixedly connected to the inner wall of the air inlet pipe 141. A rotating ring 143 is rotatably connected inside the fixed limiting ring 142. A plurality of sealing plates 431 are fixedly connected to the inner wall of the rotating ring 143. The plurality of sealing plates 431 are arranged in a circumferential array. A fixed block 432 is fixedly connected to the bottom of the rotating ring 143. The bottom of the fixed block 432 penetrates through the air inlet pipe 141 and extends to the outside. The fixed block 432 is slidably connected to the air inlet pipe 141. A fixed rod 433 is fixedly connected to the left side of the fixed block 432. A first connecting block 434 is fixedly connected to the left side of the fixed rod 433. By providing the air inlet adjusting assembly 14, specifically, starting the second electric push rod 161 drives the connecting plate 162 to move upward or downward. Then, the connecting plate 162 moves together with the slider 163, the vertical rod 164, and the second connecting block 165. The second connecting block 165 drives the rotating ring 143 to rotate clockwise or counterclockwise on the fixed limiting ring 142 through the fixed shaft 166, the first connecting block 434, the fixed rod 433, and the fixed block 432. The size of the air inlet notch 15 is adjusted by the rotation of the sealing plate 431, thereby controlling the air intake volume, and the air volume blown out can be adjusted again to achieve better air volume control.

[0030] A support plate 16 is fixedly connected to the left rear side of the air duct 1. A second electric push rod 161 is fixedly connected to the top of the support plate 16. The output end of the second electric push rod 161 at the bottom is fixedly connected to a connecting plate 162. A chute is formed inside the connecting plate 162. A slider 163 is slidably connected to the inner wall of the chute. A vertical rod 164 is fixedly connected to the bottom of the slider 163. A second connecting block 165 is fixedly connected to the bottom of the vertical rod 164. A fixed shaft 166 is fixedly connected to the rear side of the second connecting block 165. The rear side of the fixed shaft 166 penetrates through the first connecting block 434 and extends to the outside. Since the slider 163 slides inside the connecting plate 162 and the first connecting block 434 rotates on the fixed shaft 166, the first connecting block 434 drives the rotating ring 143 to rotate clockwise or counterclockwise on the fixed limiting ring 142 through the fixed rod 433 and the fixed block 432.

[0031] The first connecting block 434 is rotatably connected to the fixed shaft 166. The front side of the first connecting block 434 contacts the rear side of the second connecting block 165. The front sides of the rotating ring 143 and the sealing plate 431 both contact the rear side of the air duct 1. The front side of the air inlet pipe 141 is fixedly connected to the rear side of the air duct 1.

[0032] A specific application of this embodiment is:

[0033] Start the fan 2 to generate suction, suck in external air through the air inlet slot 15, and then discharge it from the front of the air duct 1. Start the first electric push rod 121 to drive the push block 122 to move to the left, then the rack 123 moves to the left on the limit track 124, and the rack 123 drives the gear 133 to rotate counterclockwise. The rotating shaft 132 drives the adjusting fan blades 131 to rotate counterclockwise, so that the gap between the two adjusting fan blades 131 decreases, reducing the air volume. And after the adjusting fan blades 131 rotate, they are in an inclined state. Therefore, the wind will be decelerated after passing through the adjusting fan blades 131, thus achieving the effect of speed reduction. When the first electric push rod 121 drives the push block 122 to move to the right, the adjusting fan blades 131 reverse and flip, thus increasing the gap between the two adjusting fan blades 131 and increasing the air volume, thereby improving the adjustment efficiency. There is no need for manual adjustment, improving the effect of chemical fiber filament formation and reducing the situation of waste filaments. By starting the second electric push rod 161 to drive the connecting plate 162 to move up or down, the connecting plate 162 drives the second connecting block 165 to move together through the slider 163 and the vertical rod 164. The second connecting block 165 drives the first connecting block 434 to move through the fixed shaft 166. Since the slider 163 slides in the connecting plate 162 and the first connecting block 434 rotates on the fixed shaft 166, the first connecting block 434 drives the rotating ring 143 to rotate clockwise or counterclockwise on the fixed limit ring 142 through the fixed rod 433 and the fixed block 432. The sealing plate 431 rotates together with the rotating ring 143. By rotating the sealing plate 431, the size of the air inlet slot 15 is adjusted. When the rotating ring 143 rotates clockwise, the air inlet slot 15 decreases. When the rotating ring 143 rotates counterclockwise, the air inlet slot 15 increases, thus controlling the air intake volume. The blown air volume can be adjusted again. When the adjustment effect of the air volume adjustment assembly 13 is not good enough, the air intake of the air intake adjustment assembly 14 can be controlled to achieve better air volume control.
