Description

Technical Field

[0001] The utility model relates to the technical field of air volume regulation, in particular to a novel side-blowing air volume regulating device. Background Art

[0002] Side-blown air cooling is an important process in the chemical fiber spinning process. After the tow leaves the spinneret, temperature- and humidity-controlled side-blown air is blown into the direction perpendicular to the movement of the tow for cooling. Since different types of tows require different wind speeds, an air volume regulating device is usually provided in the upper air duct of the side-blown bellows. The existing air volume regulating device connects the blades through a connecting rod, and the blades are separated by partitions. The air volume is adjusted by rotating the worm gear and the fan blades. Since there is a gap between the blades and the partition, when the air volume regulating device is not in operation, wind still passes through the gap, making abnormal noise and wasting resources; when in operation, since the structure of the existing blades is too thin, when the distance is too large, the fan blades and the partitions will vibrate under the action of the wind, making abnormal noise.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limitations on the utility model.

[0029] like Figure 1 and Figure 2 As shown, a new side-blowing air volume regulating device of an embodiment of the utility model is used to cool different types of textile yarn bundles by temperature- and humidity-controlled side-blowing air, and includes a plurality of blades 1, a shell 2, and an active component 3 and a driven component 4 fixedly connected to the shell 2.

[0030] like Figure 3 As shown, the blade 1 includes a main body 10, a first bending portion 11 and a second bending portion 12. The first bending portion 11 is formed by folding one end of the blade 1 downward, and the second bending portion 12 is formed by folding the other end of the blade 1 upward; the main body 10 includes a first end surface 100 and a second end surface 101; the first bending portion 11 includes a first folding surface 110, the first end surface 100 is fitted with the first folding surface 110, and the second bending portion 12 includes a second folding surface 120, the second end surface 101 is fitted with the second folding surface 120, which increases the thickness of the edge of the blade 1 and makes the structure of the blade 1 more stable.

[0031] The main body 10 also includes a first groove 102 and a second groove 103 for increasing the mechanical strength of the blade 1. According to the preferred embodiment of the utility model, the first groove 102 and the second groove 103 are preferably V-shaped grooves. A third groove 104 is formed between the first groove 102 and the second groove 103, and a plurality of screw holes 105 are opened on the third groove 104.

[0032] like Figure 4As shown, corresponding to the preferred embodiment of the utility model, the specific number of the plurality of blades 1 is 4 groups. The first bending portion 11 also includes a first fitting surface 111; the second bending portion 12 also includes a second fitting surface 121. When the air volume regulating device is not working, the first fitting surface 111 and the second fitting surface 121 of two adjacent blades 1 fit each other. The shell 2 includes a third side panel 22 and a fourth side panel 23; the inner wall of the third side panel 22 is fixedly connected to the first baffle 24 through a seal, and the inner wall of the fourth side panel 23 is fixedly connected to the second baffle 25 through a seal. Among them, the length of the first baffle 24 and the second baffle 25 is equal to the length of the blade 1. The first baffle 24 is located above the first fitting surface 111 of the first blade 1 and fits with the first fitting surface 111; the second baffle 25 is located below the second fitting surface 121 of the fourth blade 1 and fits with the second fitting surface 121. The mutual contact between the first contact surface 111 and the second contact surface 121, the first contact surface 111 and the first stop bar 24, and the second contact surface 121 and the second stop bar 25 makes the air volume regulating device more sealed when not in operation.

[0033] like Figure 5 and Figure 7 As shown, the distance between the planes where the center lines of the first bending portion 11 and the second bending portion 12 of two adjacent blades 1 are located is the distance H, and the distance H is proportional to the amount of air passing through. The larger the distance H, the larger the air volume and the better the cooling effect. In the non-working state, the first fitting surface 111 fits with the second fitting surface 121, and the distance H is the minimum distance H1, where H1 is equal to 0. In the working state, the active component 3 can adjust the distance H between the blades 1, wherein the shell 2 also includes a first side plate 20, the inner wall of the first side plate 20 is fixedly connected to the stopper 26 through a seal, and the stopper 26 is located directly above the first blade 1. When the second fitting surface 121 of the first blade 1 abuts against the stopper 26, the distance H is the maximum distance H3.

[0034] like Figure 8 As shown, the active part assembly 3 includes a power box 38, a spindle 32, a blade shaft 34 and an active lining plate 37. The active lining plate 37 is fixedly connected to the outer wall of the first side plate 20 of the shell 2 by screws, and the bottom of the box body 380 of the power box 38 is fixedly connected to the active part lining plate 37 by screws. A worm gear 30 and a worm 31 meshing with the worm gear 30 are installed inside the power box 38. The worm gear 30 is sleeved on the blade shaft 34, and the worm 31 is penetrated inside and sleeved on the spindle 32. When the spindle 32 is rotated, the worm 31 rotates accordingly, and the worm gear 30 drives the blade shaft 34 to rotate. The screw 6 passes through the screw hole 105 to fix the blade shaft 34 to the third groove 104 of the first blade 1.

[0035] The active part assembly 3 also includes three sets of first bearing assembly 33 fixedly connected to the other three blades 1, and the first bearing assembly includes a first bearing seat 330 and a first shaft 331 matched with the first bearing seat 330. The first side plate 20 is provided with a first through hole 200, and the first bearing seat 330 is embedded in the first through hole 200 and fixedly connected to the first side plate 20 by screws. The screw 6 passes through the screw hole 105 to fix the first shaft 331 to the third groove 104 of the blade 1.

[0036] The active part 3 also includes a pointer sleeve 35 and a dial 36 abutting against the pointer sleeve 35. The dial 36 is fixedly connected to the box cover 381 of the power box 38 by screws. The box cover 381 is provided with a third through hole 382, ​​and the fan shaft 34 passes through the third through hole. The pointer sleeve 35 is sleeved on the fan shaft 24 and fixedly connected to the fan shaft 34 by a bolt 5.

[0037] like Fig. 9 As shown, the driven part assembly 4 includes four groups of swing arms 40, connecting rods 41, four groups of second bearing combinations 43 and driven linings 44. The housing 2 also includes a second side plate 21, and the driven lining 44 is fixedly connected to the outer side of the second side plate 21 by screws. The second bearing combination 43 includes a second bearing seat 430 and a second rotating shaft 431 matched with the second bearing seat 430; a second through hole 210 is opened on the second side plate 21, and the second bearing seat 430 is embedded in the second through hole 210 and fixedly connected to the second side plate 21 by screws. The screw 6 passes through the screw hole 105 to fix one end of the second rotating shaft 431 to the third groove 104 of the blade 1, and the other end is fixedly connected to the swing arm 40 by the bolt 5. The swing arm 40 is fixedly connected to the connecting rod 41 by a pin 42.

[0038] In the working state, the spindle 32 is rotated, and the spindle 32 drives the worm 31 and the worm gear 30 to rotate, and the worm gear 30 drives the blade shaft 34 to rotate. The blade shaft 34 drives the first blade 1 to rotate, and under the linkage action of the connecting rod 41, the other three blades 1 also rotate accordingly. The pointer sleeve 35 and the dial 36 can feedback the rotation angle of the current blade 1. When the second folding surface 14 of the first blade 1 abuts against the stopper 26, the maximum distance H3 is reached. In the non-working state, the spindle 32 is reversed until the first fitting surface 106 and the second fitting surface 107 of the two adjacent blades 1 are in contact with each other; the first stop bar 24 is located above the first fitting surface 111 of the first blade 1 and is in contact with the first fitting surface 111; the second stop bar 25 is located below the second fitting surface 121 of the fourth blade 1 and is in contact with the second fitting surface 121, and is at the minimum distance H1 at this time.

[0039] The new side-blowing air volume regulating device of one embodiment of the utility model increases the mechanical strength of the blade 1 by setting the first groove 102 and the second groove 103 as a V-shaped groove, making the structure more solid. By setting the first bending portion 11 and the second bending portion 12 on the blade, the thickness of the blade 1 is increased, the vibration generated during operation is reduced, and the mute effect is improved. In the non-working state, the first bonding surface 111 and the second bonding surface 121, the first bonding surface 111 and the first baffle 24, and the second bonding surface 121 and the second baffle 25 are mutually bonded, thereby improving the sealing of the device and saving resources. By using the worm wheel 30 and the worm 31 as the active component, its self-locking effect can keep the blade fixed after rotating a certain angle.

[0040] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
