Description

Technical Field

[0001] The invention relates to the field of roving blowers, in particular to a roving blower capable of changing the air volume. Background Art

[0002] The cotton textile industry is often accompanied by flying dust during the production process. These flying dust falls in a dry place to form cotton balls, affecting the production environment. Flying catkins mixed with roving strips will cause uneven slivers, which will directly reduce the quality of the roving in severe cases. Moreover, these fibers are flammable, and allowing them to scatter will increase hidden dangers in the workshop. Therefore, thorough cleaning is a key link to ensure the workshop environment, product quality, machine life, and especially production. In the existing technology, roving fans are mostly used to collect flying catkins.

[0003] Existing roving fans are mostly installed on a mobile structure and move back and forth on the production line to suck in the flying catkins on the production line. After the flying catkins enter the pipeline, they are uniformly processed by the negative pressure system. A baffle is generally provided at one end of the negative pressure air duct to block the air suction port for collecting the flying catkins. When the amount of flying catkins is large, the existing technology often achieves multi-angle flying catkin collection by increasing the diameter of the roving fan pipeline.

[0004] However, the existing coarse yarn fans are often unable to adjust the air volume of the air intake well, and often operate at the same power. When the amount of flying catkins is small, continuously running the coarse yarn fan at a high speed is likely to cause unnecessary waste. Simply reducing the power of the fan motor is likely to cause insufficient negative pressure at the air inlet, thereby failing to collect the flying catkins well. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a coarse yarn blower with variable air volume, so as to solve the technical problem that the existing coarse yarn blower is often unable to adjust the air volume of the incoming air well.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a coarse yarn blower capable of changing the air volume, comprising a fixed cylinder, the fixed cylinder being connected to a movable cylinder via a connecting structure, the end of the movable cylinder being connected to a mounting box, the mounting box being a columnar structure with openings at both ends, a plurality of groups of wind shields being rotatably connected in the mounting box, one side of the plurality of groups of wind shields being fixedly connected to movable shafts, the plurality of groups of movable shafts being slidably connected in an adjusting ring, an arc groove for matching the movable shaft being provided on the adjusting ring, a gear ring being fixedly connected to the periphery of the adjusting ring, an air outlet adjusting motor being provided on the outer wall of the mounting box, the output end of the air outlet adjusting motor being inserted into the mounting box and fixedly connected to a driving gear, the driving gear being meshed with the gear ring.

[0007] By adopting the above technical solution, an installation box is set at the end of the pipe, and a driving motor is set on the back of the installation box. The driving motor drives the adjustment ring to rotate, and the arc groove on the adjustment ring cooperates with the movable shaft on the wind shield to make the wind shields connected to the installation box rotate at equal intervals in a ring shape and rotate at the same time. Due to the special arc structure of the wind shield itself, when all the wind shields rotate at the same time, the size of the inner diameter of the installation box can be adjusted, thereby achieving the purpose of conveniently adjusting the air volume.

[0008] The present invention is further configured such that one end of the fixed cylinder is rotatably connected to a first swivel, the first swivel is fixedly connected to a first connecting frame, the other end of the first connecting frame is rotatably connected to a second swivel, the other side of the second swivel is fixedly connected to a second connecting frame, the other end of the second connecting frame is rotatably connected to a third swivel, and the third swivel is rotatably connected to a movable cylinder.

[0009] By adopting the above technical solution, the multi-angle adjustment of the air inlet of the fan can be achieved through the structure of multiple groups of connecting frames and rotating rings to adapt to the collection of flying catkins in a larger range.

[0010] The present invention is further configured such that a fan unit is arranged in the fixed cylinder.

[0011] By adopting the above technical solution, negative pressure is created by the operation of the fan unit, and the flying catkins in the air are sucked in by the negative pressure.

[0012] The present invention is further configured such that the connecting structure between the fixed cylinder and the movable cylinder is covered with a flexible sleeve.

[0013] By adopting the above technical solution, the flexible sleeve can maintain good air tightness at the connection structure, and can also enable the connection structure to rotate normally.

[0014] The present invention is further configured such that both the first connecting frame and the second connecting frame are triangular structures.

[0015] By adopting the above technical solution, the triangular structured connecting frames cooperate with each other so that the movable cylinder can face a more complex angle.

[0016] The present invention is further configured such that a plurality of groups of fixed shafts are evenly spaced in a ring shape in the installation box, and the wind shield is rotatably connected to the fixed shafts.

[0017] By adopting the above technical solution, the wind shield rotates around the fixed axis.

[0018] The present invention is further configured such that the plurality of groups of wind shields are not located in the same plane.

[0019] By adopting the above technical solution, it is avoided that the wind shields affect each other and cannot rotate during the rotation process.

[0020] The present invention is further configured such that the inner wall of the installation box is provided with a ring groove for the adjustment ring to rotate, and a groove for the gear ring to rotate is provided on the periphery of the ring groove.

[0021] By adopting the above technical solution, displacement of the adjusting ring under the drive of the driving gear is avoided.

[0022] The present invention is further configured such that the adjustment ring in the installation box is coaxial with the installation box.

[0023] By adopting the above technical solution, the adjustment ring can evenly move multiple groups of wind shields according to the set trajectory, thereby achieving the purpose of adjusting the opening size.

[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] 1. The present invention arranges a mounting box at the end of the pipeline, arranges a driving motor at the back of the mounting box, drives the adjusting ring to rotate by the driving motor, and uses the arc groove on the adjusting ring to cooperate with the movable shaft on the wind shield to make the wind shield connected to the mounting box rotate at the same time in an annular equidistant interval. Due to the special arc structure of the wind shield itself, when all the wind shields rotate at the same time, the size of the inner diameter of the mounting box can be adjusted, thereby achieving the purpose of conveniently adjusting the air volume;

[0026] 2. The present invention sets a plurality of groups of rotating rings, fixes an inclined frame structure between the rotating rings, and sets a motor on the frame structure to drive the rotating rings to rotate. When the motor is working, each group of rotating rings can rotate about its own axis. When reflected on the entire device, the movable cylinder can be freely adjusted at multiple angles, thereby achieving the purpose of better and more conveniently collecting flying catkins in all directions.

DETAILED DESCRIPTION

[0034] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The following describes an embodiment of the present invention based on its overall structure.

[0036] A roving fan with variable air volume, such as Figure 1-6 As shown, it includes a fixed cylinder 1, which is connected to a movable cylinder 2 through a connecting structure, and the end of the movable cylinder 2 is connected to a mounting box 3, which is a columnar structure with openings at both ends. Multiple groups of wind shields 4 are rotatably connected in the mounting box 3, and one side of the multiple groups of wind shields 4 are fixedly connected with movable shafts 8, and the multiple groups of movable shafts 8 are slidably connected in an adjusting ring 9. The adjusting ring 9 is provided with an arc groove 10 for matching the movable shaft 8, and the periphery of the adjusting ring 9 is fixedly connected with a gear ring 11, and an air outlet regulating motor 5 is provided on the outer wall of the mounting box 3, and the output end of the air outlet regulating motor 5 is inserted into the mounting box 3 and fixedly connected with a driving gear 6, which is meshed with the gear ring 11, and the rotation of the air outlet regulating motor 5 is controlled to realize the rotation adjustment of the wind shield 4, thereby adjusting the air volume passing through the mounting box 3.

[0037] A fan unit 13 is arranged in the fixed cylinder 1. Negative pressure is created by the operation of the fan unit 13, and flying catkins in the air are sucked in by the negative pressure. The motor in the fan unit 13 is specifically a frequency-modulated motor. When necessary, the wind speed can be controlled by adjusting the power of the motor in the fan unit 13, and the opening adjustment mechanism at the movable cylinder 2 can be used to further control the air volume.

[0038] On the basis of the above structure, in this embodiment, one end of the fixed cylinder 1 is rotatably connected to the first rotating ring 14, the first rotating ring 14 is fixedly connected to the first connecting frame 15, the other end of the first connecting frame 15 is rotatably connected to the second rotating ring 16, the other side of the second rotating ring 16 is fixedly connected to the second connecting frame 17, the other end of the second connecting frame 17 is rotatably connected to the third rotating ring 18, the third rotating ring 18 is rotatably connected to the movable cylinder 2, and the multi-angle adjustment of the air inlet of the fan is realized through the structure of multiple groups of connecting frames and rotating rings to adapt to a larger range of flying catkins collection work. Specifically, the first rotating ring 14, the second rotating ring 16, and the third rotating ring 18 are all structures in which two groups of circular rings are connected by bearings, and encoding motors are arranged at the first rotating ring 14, the second rotating ring 16, and the third rotating ring 18. The output end of the encoding motor is provided with a gear, and the gear is meshed with the gear ring on the inner surface of the first rotating ring 14, the second rotating ring 16, and the third rotating ring 18. The working state of the encoding motor is controlled by the editing program in the prior art, so as to conveniently achieve the purpose of controlling the direction of the movable cylinder 2.

[0039] On the basis of the above structure, in this embodiment, negative pressure is created by the operation of the fan unit 13, and the flying catkins in the air are sucked in by the negative pressure. The flexible sleeve 12 maintains good air tightness at the connection structure and also enables the connection structure to rotate normally.

[0040] On the basis of the above structure, in this embodiment, the first connecting frame 15 and the second connecting frame 17 are both triangular structures, and the connecting frames of the triangular structure cooperate with each other to enable the movable cylinder 2 to be oriented to more complex angles. Specifically, the first connecting frame 15 and the second connecting frame 17 of the triangular structure are both fixedly connected to one side of the adjacent rotating ring structure, that is, a group of circular rings close to two adjacent groups of rotating ring structures are fixedly connected and rotate synchronously. Furthermore, the first connecting frame 15 and the second connecting frame 17 are both cylindrical connecting rod structures, which can avoid flying catkins adhering to the connecting frame structure and causing blockage as much as possible.

[0041] On the basis of the above structure, in the present embodiment, a plurality of fixed shafts 7 are evenly spaced in an annular shape in the installation box 3, and the wind shield plate 4 is rotatably connected to the fixed shaft 7, and the wind shield plate 4 rotates around the fixed shaft 7, and the plurality of wind shield plates 4 are not in the same plane, so as to avoid the wind shield plates 4 affecting each other and being unable to rotate during the rotation process. The inner wall of the installation box 3 is provided with an annular groove for the rotation of the adjusting ring 9, and a groove for the rotation of the gear ring 11 is provided on the periphery of the annular groove, so as to avoid the displacement of the adjusting ring 9 under the drive of the driving gear 6. The adjusting ring 9 in the installation box 3 is coaxial with the installation box 3, so that the adjusting ring 9 can evenly make the plurality of wind shield plates 4 move according to the set trajectory. Specifically, when the adjusting ring 9 rotates, the movable shaft 8 on the wind shield plate 4 slides in the arc groove 10 in the adjusting ring 9, and since the wind shield plate 4 is rotatably connected to the fixed shaft 7, the plurality of wind shield plates 4 will rotate around the fixed shaft 7, thereby achieving the purpose of adjusting the opening size.

[0042] The present invention creatively sets up a fan structure that can easily adjust the direction and opening angle, thereby avoiding the shortcoming that existing coarse yarn fans are often unable to adjust the air volume of the incoming air well; in this solution, a mounting box is arranged at the end of the pipe, and a driving motor is arranged on the back of the mounting box. The driving motor drives the adjustment ring to rotate, and the arc grooves on the adjustment ring are used to cooperate with the movable shafts on the wind shields to make the wind shields connected to the mounting box in a ring-shaped and equidistant rotation at intervals rotate at the same time. Due to the special arc structure of the wind shields themselves, when all the wind shields rotate at the same time, the size of the inner diameter of the mounting box can be adjusted, thereby achieving the purpose of conveniently adjusting the air volume.
