Description

Technical Field

[0001] This utility model relates to the field of roller sheath technology, and in particular to a roller structure for zoned control of traction force. Background Technology

[0002] In textile machinery, the roller is a key component, its main function being to generate friction between the front and rear roller skins and the fabric, thereby achieving traction and control of the fabric. However, the uniform distribution of tension force in traditional rollers results in no difference in tension force between the working area (i.e., the area where the roller skin contacts the fabric) and the non-working area (the areas where the roller ends contact the yarn or the idle portion). This structure cannot provide a sufficiently large and stable tension force in the working area, affecting the fabric's drafting effect and quality. Simultaneously, the unnecessarily large friction force in the non-working area not only increases energy loss but also easily causes yarn wear and breakage, leading to yarn waste, reduced yarn utilization, and increased production costs. Therefore, there is an urgent need to improve the existing roller structure. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a roller structure for zoned control of tensile force.

[0004] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0005] A roller structure for zoned control of traction force includes a drive unit and a roller sleeve fitted on the drive unit. The roller sleeve includes an integrally formed working roller sleeve and a non-working roller sleeve. The working roller sleeve is located in the middle and has a protrusion extending axially along the drive unit. There are two non-working roller sleeves located on the left and right sides of the working roller sleeve. The non-working roller sleeves have grooves, the width of which is greater than the width of the protrusion, and the interval between the grooves is greater than the interval between the protrusions.

[0006] Preferably, the ribs are evenly distributed on the working roller sleeve, with a width of 2mm to 5mm and a spacing of 4mm to 10mm between the ribs.

[0007] Preferably, the grooves are evenly distributed on the non-working roller sleeve, with a groove width of 4mm to 8mm and a groove spacing of 8mm to 12mm.

[0008] Preferably, the groove is a serrated annular groove.

[0009] Preferably, the drive unit includes a main rotating shaft and a driven rotating shaft, with a spacer block installed between the main rotating shaft and the driven rotating shaft; both the main rotating shaft and the driven rotating shaft are round shafts, with the diameter of the main rotating shaft being larger than the diameter of the driven rotating shaft, and the spacer block having arc surfaces that respectively mate with the main rotating shaft and the driven rotating shaft.

[0010] Preferably, the drive unit also includes a transmission gearbox and a roller mounting base, with one end of the main rotating shaft and the driven rotating shaft fixedly connected to the transmission gearbox, and the other end of the main rotating shaft and the driven rotating shaft mounted on the roller mounting base.

[0011] This utility model has significant technical effects due to the adoption of the above technical solutions: The purpose of this utility model is to provide a roller structure for zoned control of tension force. By differentiating the contact surfaces of the roller skin, it can enhance the tension force in the working area and provide intermittent tension force in the non-working area, thereby improving the stability of tension force, reducing yarn waste and reducing energy consumption.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0017] Example 1

[0018] A roller structure for zoned control of traction force, as shown in the figure, includes a drive unit and a roller sleeve 1 sleeved on the drive unit. The roller sleeve 1 includes an integrally formed working roller sleeve 11 and non-working roller sleeves 12. The working roller sleeve 11 is located in the middle and has a protrusion 111 extending axially along the drive unit. There are two non-working roller sleeves 12 located on the left and right sides of the working roller sleeve 11. The non-working roller sleeves 12 have grooves 121, the width of which is greater than the width of the protrusion 111, and the spacing between the grooves 121 is greater than the spacing between the protrusions 111.

[0019] Example 2

[0020] Similar to Example 1, except that the ridges 111 are evenly distributed on the working roller sleeve 11, the width of the ridges 111 is 4mm, and the interval between the ridges 111 is 7mm.

[0021] The raised strips 111 are parallel to each other and evenly distributed, which can maximize the friction between the roller skin and the fabric while ensuring the normal passage of the fabric, thereby improving the tension in the working area.

[0022] Example 3

[0023] Similar to Example 1, except that the grooves 121 are evenly distributed on the non-working roller sleeve 12, the width of the grooves 121 is 6mm, and the interval between the grooves 121 is 10mm.

[0024] Groove 121 is a serrated annular groove.

[0025] The texture of the groove 121 can effectively pull the yarn so that it will not spring back due to the loss of tension. The concave part of the groove 121 can reduce the contact between the roller skin and the yarn, and the yarn will temporarily lose tension. The relatively raised part at the interval of the groove 121 and the groove 121 circulate in contact with the yarn, which can exert a certain tension on the yarn without wasting yarn due to continuous contact. This improves the effective utilization rate of the yarn and ensures the efficient and stable operation of textile production.

[0026] Example 4

[0027] Similar to Embodiment 1, the difference is that the drive unit includes a main rotating shaft 2 and a driven rotating shaft 3, with a spacer block 4 installed between them. Both the main rotating shaft 2 and the driven rotating shaft 3 are round shafts, with the diameter of the main rotating shaft 2 being larger than that of the driven rotating shaft 3. The spacer block 4 has arc surfaces that respectively mate with the main rotating shaft 2 and the driven rotating shaft 3. The spacer block 4 serves as support and spacing between the main rotating shaft 2 and the driven rotating shaft 3, and the roller skin is tightly fitted onto the outer surfaces of the main rotating shaft 2 and the driven rotating shaft 3.

[0028] The drive unit also includes a transmission gearbox 5 and a roller mounting base 6. One end of the main rotating shaft 2 and the driven rotating shaft 3 are fixedly connected to the transmission gearbox 5, and the other end of the main rotating shaft 2 and the driven rotating shaft 3 are mounted on the roller mounting base 6.

[0029] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
