Description

Technical Field

[0001] The present disclosure relates to the technical field of textile equipment, and in particular to a winding device for a small circular knitting machine. Background Art

[0002] Circular knitting machines are a common type of textile machinery, primarily used to weave a variety of knitted fabrics, such as underwear, T-shirts, and socks. The winding mechanism is a critical component of a circular knitting machine's operation, responsible for winding the woven fabric for subsequent cutting, sewing, and other processes. However, existing circular knitting machine winding mechanisms utilize a fixed-gear transmission system, typically consisting of a series of gears and belts.

[0042] Reference Figures 1-6 A winding device for a small circular knitting machine includes a cloth winding support 1 and a pulling assembly 2. The pulling assembly 2 is arranged on the cloth winding support 1. The cloth winding support 1 includes a bearing seat 11, a first adjustment box 12 and a second adjustment box 13. The first adjustment box 12 and the second adjustment box 13 are respectively provided with two groups and symmetrically distributed on both sides of the bearing seat 11. The pulling assembly 2 includes a traction component 21 and a winding roller 22. The traction component 21 and the winding roller 22 are rotatably arranged between the first adjustment box 12 and the second adjustment box 13. The traction component 21 includes a traction roller 211 and a roller roller 212. The traction roller 211 and the roller roller 212 are used to pull the cloth, so that the cloth flows to the position of the winding roller 22, and the cloth is rolled up by the rotation of the winding roller 22.

[0043] Two groups of symmetrically distributed stepping drive components 3 are provided on the bearing seat 11, and the stepping drive components 3 include a driving motor 31. The driving motor 31 is a servo driving motor in the prior art. The two groups of driving motors 31 are respectively installed in the first adjusting box 12 and the second adjusting box 13. The first adjusting box 12 and the second adjusting box 13 are respectively provided with a traction rotation assembly 4 and a reel rotation assembly 5. The traction rotation assembly 4 includes a first double gear 41 and a second double gear 42. The first double gear 41 and the second double gear 42 are both installed in the first adjusting box 12 through a shaft. A driving gear 311 is installed on the driving motor 31 located in the first adjusting box 12. The driving gear 311 is meshed with the large gear of the first double gear 41. The small gear of the first double gear 41 is connected to the large gear of the second double gear 42 by a chain. One end of the traction roller 211 extends into the first adjusting box 12 and is installed with a driven gear 2111. The driven gear 2111 is meshed with the small gear of the second double gear 42.

[0044] The reel rotating assembly 5 includes a driven sprocket 51 and a driving sprocket 52. The driven sprocket 51 is mounted on the portion of one end of the reel roller extending into the second adjustment box 13. The driving sprocket 52 is mounted on the drive motor 31 in the second adjustment box 13. The driven sprocket 51 and the driving sprocket 52 are connected by a chain.

[0045] A tension adjustment assembly 6 is further provided in the first adjustment box 12 . The tension adjustment assembly 6 is located between the first duplex gear 41 and the second duplex gear 42 .

[0046] Based on the above structure, the traction rotation component 4 is used to drive the traction roller 211 to rotate, and the reel rotation component 5 is used to drive the reel roller 22 to rotate. When the traction roller 211 needs to be rotated, the driving motor 31 located on one side of the first adjustment box 12 drives the first double gear 41 to rotate through the active gear 311, so that the second double gear 42 connected by the chain rotates synchronously and drives the driven gear 2111 to rotate, so that when the cloth is on the traction roller 211, the cloth is pulled by the traction roller 211, and as the rotation speed of the driving motor 31 increases, the traction roller 211 rotates. The rotation speed of 211 will also change synchronously. When the driving motor 31 located in the second adjustment box 13 rotates, it will drive the active sprocket 52 to rotate, and drive the driven sprocket 51 to rotate synchronously through the chain, thereby realizing the rotation of the winding roller 22. The traction roller 211 and the winding roller 22 are driven to rotate by connecting the two sets of stepping drive components 3 with the traction rotation component 4 and the tension adjustment component 6. The traction roller 211 and the winding roller 22 can be adjusted to the frequency and speed of rotation according to actual conditions, thereby solving the problem of the range and step length of the existing cloth winding device, and cannot achieve continuous speed adjustment.

[0047] In one embodiment, referring to Figure 1 、 Figure 2 and Figure 4 The tension adjustment assembly 6 includes a support plate 61, a first tensioning sprocket 62, and a second tensioning sprocket 63. The first tensioning sprocket 62 and the second tensioning sprocket 63 are rotatably arranged on the support plate 61 through a shaft. The first tensioning sprocket 62 and the second tensioning sprocket 63 are spaced apart and distributed at both ends of the support plate 61.

[0048] A support shaft 121 is provided in the first adjustment box 12, and the support plate 61 is rotatably provided on the support shaft 121. The support shaft 121 is located below the support plate 61, so that the first tensioning sprocket 62 and the second tensioning sprocket 63 have a degree of rotational freedom with the support shaft 121 as the center.

[0049] The chain mounted on the first duplex gear 41 and the second duplex gear 42 is connected to the first tensioning sprocket 62 and the second tensioning sprocket 63. The tension adjustment assembly 6 further includes a tension spring 64. A mounting seat 122 is further provided in the first adjustment box 12. The mounting seat 122 is located on one side of the support plate 61.

[0050] A protrusion 611 is provided on one side of the support plate 61 close to the support shaft 121, and the two ends of the tension spring member 64 are respectively connected to the mounting seat 122 and the protrusion 611. Through the setting of the tension spring member 64, the degree of deformation of the tension spring member 64 can be adjusted to change the rotation angle of the support plate 61. Since the first tensioning sprocket 62 and the second tensioning sprocket 63 are both connected to the chain, when the support plate 61 rotates, the angles of the first tensioning sprocket 62 and the second tensioning sprocket 63 change synchronously, thereby changing the chain, thereby changing the rotation speed and frequency of the second double gear 42, and realizing the change of the rotation speed of the traction roller 211, so as to be suitable for different types of fabrics.

[0051] In one embodiment, referring to Figure 1 、 Figure 2 and Figure 5 A sliding seat 14 is provided on the opposite side of the first adjustment box 12 and the second adjustment box 13. A screw component 141 is rotatably provided in the sliding seat 14. One end of the screw component 141 is set to the outside of the sliding seat 14 and is installed with a handwheel. A slider 142 is installed on the screw component 141. Both ends of the roller roller 212 are rotatably provided on the slider 142. When the operator rotates the handwheel at the same time to rotate the screw component 141, the slider 142 drives the roller roller 212 to move along the rotation direction of the screw component 141.

[0052] Through the cooperation of the screw component 141 and the slider 142, the roller roller 212 is moved closer to or away from the traction roller 211, and an accommodating area for the cloth to pass through is formed between the roller roller 212 and the traction roller 211. By adjusting the distance between the roller roller 212 and the traction roller 211, it can adapt to cloths of different specifications, and the tension of the cloth can be controlled more accurately to avoid wrinkles or loosening of the cloth during transmission, thereby improving the flexibility of the traction component 21.

[0053] In one embodiment, referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The stepping drive component 3 further includes a driver 32, which is a servo driver in the prior art. The driver 32 is electrically connected to the drive motor 31, and the driver 32 provides power for the rotation of the drive motor 31. The driver 32 is located on the supporting base 11, and a protective cover 15 is movably installed on the supporting base 11. When the protective cover 15 is installed on the supporting base 11, the driver 32 is located inside the protective cover 15;

[0054] A magnetic layer 151 is provided on the inner walls on both sides of the protective cover 15. When the protective cover 15 is installed on the supporting base 11, the supporting base 11 is made of metal iron, and the protective cover 15 is magnetically connected to the supporting base 11. The protective cover 15 can be quickly installed on the supporting base 11 through the magnetic connection, and the protective cover 15 can be quickly taken away through the magnetic connection, thereby realizing maintenance or replacement of the stepping drive component 3.

[0055] In one embodiment, referring to Figure 1 and Figure 2 The small gear of the first duplex gear 41 and the large gear of the second duplex gear 42 are both sprockets. The arrangement of the sprockets enables the first duplex gear 41 and the second duplex gear 42 to be connected through a chain.

[0056] In one embodiment, referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 Two sets of symmetrically distributed limit rods 16 are arranged between the first adjustment box 12 and the second adjustment box 13. The two sets of limit rods 16 are located above the traction component 21. The limit rods 16 can serve as safety components to prevent equipment damage or personal injury caused by operator misoperation, and by adjusting the position of the limit rods 16, the maximum diameter of the package can be easily changed to adapt to different production requirements.

[0057] In one embodiment, referring to Figure 1-Figure 3 A supporting turntable 111 is provided at the bottom of the supporting seat 11. Through the rotation of the supporting turntable 111, the supporting seat 11 can drive the first adjustment box 12 and the second adjustment box 13 to rotate synchronously, so that the pulling assembly 2 rotates along the rotation direction of the supporting seat 11, and the fabric is rolled up.
