Abstract
Description
A roving frame connecting rod swing device Technical Field
[0001] This utility model relates to the field of textile technology, and in particular to a roving frame connecting rod swing device. Background Technology
[0002] After the fiber sliver is drawn thin by the drafting mechanism, it is then rubbed laterally by a reciprocating rubbing plate. During this process, no traditional twist is applied; instead, the fibers are aggregated by mechanical friction. Finally, the connecting rod swing device laterally pushes a connecting rod with several bobbins to reciprocate, winding the coarse sand around the bobbins layer by layer in the circumferential direction, with each layer of coarse sand alternating in the opposite direction, forming a tube yarn structure with truncated conical ends.
[0003] The swing device drives the connecting rod to move laterally and reciprocally through the rotating cam, thereby driving the cylinder installed on it to move synchronously and reciprocally. However, when production needs change, the length of the cylinder also needs to be changed to a different length. In order to adapt to the change in cylinder length, the cam needs to be disassembled and replaced with a cam corresponding to the cylinder length, which makes the replacement operation more complicated and results in a longer downtime, thus affecting the production efficiency of coarse sand. Summary of the Invention
[0004] In view of this, the purpose of this utility model is to propose a roving frame connecting rod swing device to solve the problem that when the bobbin length changes according to production needs, it is necessary to simultaneously disassemble and replace the corresponding cam, which makes the replacement operation more complicated, resulting in a long downtime and affecting the production efficiency of roving.
[0005] To achieve the above objectives, this utility model provides a roving frame connecting rod swing device, including a support base and a strip seat slidably disposed on the top of the support base. The swing device further includes:
[0006] An amplitude adjustment part is provided between the same end of the strip base and the support base. The amplitude adjustment part includes a support block fixed to the end face of the strip base and a slide groove vertically provided on the support block. A sliding column is slidably arranged in the slide groove. A drive motor is fixed on the support base. A rocker arm is fixed to the output end of the drive motor. An adjustment component is provided between the rocker arm and the sliding column. The adjustment component is used to adjust the height of the sliding column in the slide groove so that the diameter of the circular trajectory of the sliding column moving circumferentially under the drive of the drive motor is the same as the amplitude of the horizontal push of the strip base to make reciprocating linear motion.
[0007] Preferably, the adjustment assembly includes a limiting groove on a vertical surface of the rocker arm near the sliding column and a screw rod rotatably disposed in the limiting groove. One end of the sliding column is threaded onto the outside of the screw rod, serving as a driving component for driving the screw rod to rotate.
[0008] Preferably, the driving element is a knob, and the top end of the screw passes through one end of the limiting groove and is fixed at the center of the knob.
[0009] Preferably, the adjustment assembly further includes two grooves provided on the outside of the sliding column and two limiting strips respectively fixed vertically on two opposite vertical surfaces in the limiting groove. One side of the limiting strip is slidably sleeved inside the groove, and the cooperation between the limiting strip and the groove is used to enhance the limiting and supporting strength of the sliding column.
[0010] Preferably, the slide groove is located on a vertical surface of the support block parallel to the direction of movement of the support block, and the slide groove is distributed opposite to the rocker arm.
[0011] Preferably, the rocker arm is located between the drive motor and the support block, and the rocker arm is arranged radially along the output shaft of the drive motor.
[0012] Preferably, the swing device further includes at least one guide located between the outside of the bar seat and the top of the support seat.
[0013] The guide component includes a guide groove located on the top of the support base and a limiting block slidably disposed within the guide groove, the limiting block being fixedly disposed on the outside of the strip base.
[0014] Preferably, the vertical cross-sectional shape of the guide groove is L-shaped or T-shaped, and the cross-sectional shape of the guide groove matches the vertical cross-sectional shape of the limiting block.
[0015] The beneficial effects of this utility model are:
[0016] This invention features an amplitude adjustment mechanism between the strip seat and the support seat. Since the amplitude of the transverse reciprocating motion of the strip seat matches the position of the sliding column in the groove, when the length of the bobbin changes according to production needs, the position of the sliding column in the groove can be adjusted efficiently and flexibly to make the amplitude of the reciprocating motion of the strip seat correspond to the length of the bobbin. This greatly shortens the downtime and reduces the impact on the efficiency of coarse sand winding. Attached Figure Description

[0027] As shown in Figures 1 to 5, a roving frame connecting rod swing device includes a support base 1 and a strip seat 2 slidably disposed on the top of the support base 1. The bobbin is transversely disposed on a winding mechanism on the strip seat 2. The swing device further includes:
[0028] An amplitude adjustment part 3 is provided between the same end of the strip seat 2 and the support seat 1. The amplitude adjustment part 3 includes a support block 31 fixed to the end face of the strip seat 2 and a slide groove 32 vertically provided on the support block 31. A sliding column 33 is slidably provided in the slide groove 32. A drive motor 34 is fixedly provided on the support seat 1. A rocker arm 35 is fixedly provided at the output end of the drive motor 34. An adjustment component 36 is provided between the rocker arm 35 and the sliding column 33. The adjustment component 36 is used to adjust the height of the sliding column 33 in the slide groove 32 so that the diameter of the circular trajectory of the sliding column 33 moving circumferentially under the drive of the drive motor 34 is the same as the amplitude of the horizontal push of the strip seat 2 to make reciprocating linear motion.
[0029] When the untwisted roving frame is stopped, the free end of the rocker arm 35 is positioned vertically downwards. At this time, the sliding column 33 is at its lowest position within the groove 32. After the untwisted roving frame is stopped, the previously used bobbin is replaced with a bobbin of a different length. By operating the adjusting component 36, the sliding column 33 is moved closer to or further away from the output shaft of the drive motor 34. This adjusts the diameter of the sliding column 33 as it rotates along a circular trajectory driven by the drive motor 34. The sliding column 33 and the groove 32 are coordinated such that each rotation causes the sliding column 33 to reciprocate vertically within the groove 32. With each slide, since there is only a relative vertical displacement between the sliding column 33 and the groove 32, as the sliding column 33 slides from the lowest end to the highest end of the groove 32 and then returns, the sliding column 33 pushes the support block 31 and the strip seat 2 to make one reciprocating linear movement in the horizontal direction. Since the rotation trajectory of the sliding column 33 is a fixed circle, the amplitude of the horizontal reciprocating movement of the strip seat 2 is the same as the horizontal diameter of the circular trajectory of the sliding column 33. Therefore, the amplitude of the horizontal linear reciprocating movement of the strip seat 2 can be adjusted by adjusting the distance between the sliding column 33 and the output shaft of the drive motor 34.
[0030] As shown in Figures 4 and 5, the adjustment assembly 36 includes a limiting groove 361 on the vertical surface of the rocker arm 35 near the sliding column 33 and a screw 362 rotatably disposed in the limiting groove 361. One end of the sliding column 33 is threaded onto the outside of the screw 362, and a driving component 363 is used to drive the screw 362 to rotate.
[0031] The driving component 363 is a knob. The top end of the screw 362 passes through one end of the limiting groove 361 and is fixed at the center of the knob. With this design, when it is necessary to adjust the amplitude of the horizontal linear reciprocating motion of the strip seat 2, it is only necessary to turn the knob clockwise or counterclockwise to drive the screw 362 to rotate synchronously, thereby driving the sliding column 33 to move along the axial direction of the screw 362, realizing the adjustment of the distance between the sliding column 33 and the output shaft of the drive motor 34, thereby indirectly realizing the adjustment of the amplitude of the horizontal reciprocating linear motion of the strip seat 2.
[0032] As shown in Figures 4 and 5, the adjustment assembly 36 also includes two grooves 364 located outside the sliding column 33 and two vertically fixed vertical surfaces opposite each other in the limiting groove 361. One side of the limiting strip 365 is slidably sleeved inside the groove 364. The cooperation between the limiting strip 365 and the groove 364 is used to strengthen the limiting and supporting strength of the sliding column 33, reduce the stress on the screw 362 during the reciprocating linear motion of the sliding column 33 pushing the strip seat 2, and prevent the sliding column 33 and the screw 362 from bending due to large stress, which would affect the subsequent adjustment accuracy.
[0033] As shown in Figures 1 to 3, the slide groove 32 is located on the vertical surface of the support block 31 parallel to the direction of movement of the support block 31, and the slide groove 32 is distributed opposite to the rocker arm 35, so that the strip seat 2 can be smoothly pushed to move linearly in the horizontal direction.
[0034] As shown in Figures 1 to 3, the rocker arm 35 is located between the drive motor 34 and the support block 31, and the rocker arm 35 is arranged radially along the output shaft of the drive motor 34. This design allows the sliding column 33 and the slide groove 32 to form a vertical relative displacement, while keeping them relatively stationary in the lateral direction. Thus, when the sliding column 33 slides from the highest point to the lowest point in the slide groove 32, it pushes the support block 31 to move laterally in a reciprocating linear motion, converting the circumferential rotation trajectory of the rocker arm 35 and the sliding column 33 into the linear reciprocating movement trajectory of the strip seat 2.
[0035] As shown in Figures 1 to 3, the swing device also includes at least one guide 4 located between the outside of the strip seat 2 and the top of the support seat 1.
[0036] The guide member 4 includes a guide groove 41 located on the top of the support base 1 and a limiting block 42 slidably located in the guide groove 41. The limiting block 42 is fixedly located on the outside of the strip base 2.
[0037] The vertical cross-sectional shape of the guide groove 41 is L-shaped or T-shaped, and the cross-sectional shape of the guide groove 41 matches the vertical cross-sectional shape of the limiting block 42. This design restricts the degree of freedom of the strip seat 2 except for the direction of transverse linear reciprocating motion, improves the stability of the transverse linear reciprocating motion of the strip seat 2, and thus enables the coarse sand to be evenly wrapped around the outside of the cylinder layer by layer.
[0038] Working principle: When the untwisted roving frame is stopped, the free end of the rocker arm 35 is vertically downward. At this time, the sliding column 33 is at its lowest position in the groove 32. After the untwisted roving frame is stopped, the original bobbin is replaced with a bobbin of another length. By operating the adjusting component 36, the sliding column 33 is driven to move closer to or further away from the output shaft of the drive motor 34. This adjusts the diameter of the sliding column 33 as it rotates along a circular trajectory driven by the drive motor 34. The sliding column 33 and the groove 32 work together; for every revolution of the sliding column 33, it slides vertically back and forth once within the groove 32. There is only a relative vertical displacement between 32. During the process of sliding column 33 sliding from the lowest end to the highest end of slide groove 32 and then returning, sliding column 33 pushes support block 31 and strip seat 2 to make a reciprocating linear movement in the horizontal direction. Since the rotation trajectory of sliding column 33 is a fixed circle, the amplitude of the horizontal reciprocating movement of strip seat 2 is the same as the horizontal diameter of the circular trajectory of sliding column 33. The amplitude of the horizontal linear reciprocating movement of strip seat 2 can be adjusted by adjusting the distance between sliding column 33 and the output shaft of drive motor 34. The adjustment operation can be completed by simply turning the knob, which is more efficient and simpler than disassembling and replacing cam.
