Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a tension device for a flat-width washing machine. Background Technology

[0002] A flat-width washing machine is a professional piece of equipment used for washing and processing fabrics. It is mainly used in the dyeing and printing industry for processes such as scouring, dyeing, printing, and resin finishing of fabrics. It is used to remove impurities, dyes, auxiliaries, and other substances from fabrics to improve the cleanliness of the fabrics and the effect of subsequent processing. Its core feature is that it washes the fabrics in a flat state to avoid wrinkles or deformation, and to ensure the flatness and quality stability of the processed fabrics.

[0003] Chinese Patent CN219364042U discloses a flat-width washing machine. The flat-width washing machine includes a machine body, a washing tank mounted on the machine body, and multiple washing rollers disposed within the washing tank. The multiple washing rollers are spaced apart along the fabric transport direction, with each washing roller parallel to the others and adjacent washing rollers arranged alternately vertically. The machine body is equipped with multiple beating components for beating the fabric. The beating components oscillate perpendicular to the fabric transport direction, and the machine body is equipped with a driving component for driving the beating components to oscillate. This application has the following effects: the driving component drives the beating components to oscillate, and during the oscillation process, the beating components repeatedly beat the fabric immersed in the washing tank, removing as much lint and other debris as possible from the fabric. Furthermore, the oscillation of the beating components increases the impact of the washing liquid on the fabric, further improving the cleaning effect of the washing machine and enhancing the overall quality of the finished fabric.

[0004] The above-mentioned solutions and existing technologies for flat-width washing machines typically use guide rollers on the support frame at the inlet of the washing machine to apply tension to the fabric and pull it to the washing rollers in the washing tank for washing. However, when processing fabrics of different materials and thicknesses, the guide rollers show insufficient adaptability and uneven tension. When the tension is too high, the rigid guide rollers are prone to causing excessive local stretching of the fabric, especially causing damage to thin or elastic fabrics. There is a lack of corresponding adjustable and adaptable tension device structure for flat-width washing machines, which needs to be improved and optimized. Utility Model Content

Detailed Implementation

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figures 1 to 5 This utility model provides the following two technical solutions: Example 1: A tension device for a flat-width washing machine includes a support frame 1. A first limiting groove 2 is symmetrically arranged on one side of the support frame 1, and a second limiting groove 3 is symmetrically arranged on the other side. A first slider 4 is slidably engaged within the first limiting groove 2. A first buffer roller 5 is rotatably inserted into one side of the first slider 4. A second slider 6 is slidably engaged within the second limiting groove 3. A second buffer roller 7 is rotatably inserted into the second slider 6. A tension adjusting guide fabric assembly is installed on the support frame 1. Fabric 13 is squeezed between the first buffer roller 5 and the second buffer roller 7. A first spring 9 is fixedly connected to one end of the first slider 4, and one end of the first spring 9 is fixedly connected to the first... The inner wall of the limiting slide groove 2 is provided with a second spring 10 fixedly connected to one end of the second slider 6, and the second spring 10 is fixedly connected to the inner wall of the second limiting slide groove 3. The support frame 1 consists of two sets, one of which is fixedly connected to a support plate 11. A motor 12 is fixedly connected to one end of the support plate 11. The first buffer roller 5 and the second buffer roller 7 are made of aluminum alloy roller body 501. The outer side of the aluminum alloy roller body 501 is coated with a polyurethane-nano-ceramic composite layer 502. A third limiting slide groove 14 is provided on one side of the support frame 1. A threaded hole 15 is provided on one side of the third limiting slide groove 14. Pin grooves 16 are symmetrically provided on both sides of the third limiting slide groove 14.

[0018] In use, the fabric 13 is passed sequentially through the gap between the two first buffer rollers 5 and the gap between the two second buffer rollers 7, and then through the tension adjusting guide fabric assembly and the washing roller in the water tank of the flat washing machine for washing. The elastic force of the first spring 9 in the first limiting groove 2 is less than the elastic force of the second spring 10 in the second limiting groove 3. That is, the tension of the first buffer roller 5 on the fabric 13 is greater than the tension of the second buffer roller 7 on the fabric 13, which plays a role in buffering and adjusting the fabric inlet, gradually increasing the tension, and avoiding the fabric 13 from being damaged by suddenly bearing a large tension.

[0019] Example 2: Based on Example 1, the tension adjusting guide assembly includes an adjusting slider 801, a pressing screw 804, a locking pin 806, and a drive roller 811. The adjusting slider 801 is slidably engaged with the third limiting groove 14. A third spring 802 is fixedly connected to one end of the adjusting slider 801, and a third slider 803 is fixedly connected to one side of the third spring 802. The third slider 803 is slidably engaged with the third limiting groove 14, and a guide roller 805 is fixedly connected to one end of the third slider 803. The pressing screw 804 is threaded into the threaded hole 15, and the locking pin 806 is inserted through into the pin groove 16. The drive roller 811 is rotatably connected to the support frame 1, and one end of the drive roller 811 is connected to the motor. 12; One end of the locking pin 806 is fixedly connected to a lifting connecting block 807, and one end of the lifting connecting block 807 is fixedly connected to a fourth spring 808. One side of the fourth spring 808 is fixedly connected to the support frame 1; The adjusting slider 801 is symmetrically provided with locking holes 809 on both sides, and a locking pin 806 is inserted into the locking hole 809; One end of the extrusion screw 804 is fixedly connected to an extrusion rubber head 810, and one end of the extrusion rubber head 810 extrudes the adjusting slider 801; Fabric 13 is extruded between the guide roller 805 and the drive roller 811; The guide roller 805 and the drive roller 811 are made of aluminum alloy roller body 501, and the outer side of the aluminum alloy roller body 501 is coated with a polyurethane-nano-ceramic composite layer 502.

[0020] In use, when the fabric 13 passes between the drive roller 811 and the guide roller 805 on the tension adjusting guide assembly, the drive roller 811 can be rotated by starting the motor 12 to feed and wash the fabric 13. To adjust the tension for different fabrics 13, pull the lifting connecting block 807 to disengage the locking pin 806 from the locking hole 809 on the adjusting slider 801. Then, rotate the pressing screw 804 to press the adjusting slider 801 to the appropriate position, release the lifting connecting block 807, and allow the fourth spring 808 to return to its original position. The locking pin 806 is re-inserted into the locking hole 809 for fixation, thus completing the adjustment. The compression screw 804 is fixedly connected on one side for protection. The compression force of the third spring 802 on the third slider 803 is changed, that is, the compression tension of the guide roller 805 and the drive roller 811 on the fabric 13 is changed, which can adapt to different fabrics 13. The roller body is composed of an inner aluminum alloy roller body 501 and an outer polyurethane-nano-ceramic composite layer 502, which reduces surface friction and further prevents the fabric from being damaged.
