Description

Technical Field

[0002] The dyeing machine is made of all stainless steel, and the mechanical speed regulation has the advantages of no noise and convenient speed regulation, and is suitable for dyeing operations of knitted or woven fabrics such as hemp, cotton, rayon, and blended fabrics. The untwisting device in the dyeing machine is used to relax the rope-shaped fabric to improve the dyeing quality.

[0003] When the fabric is running for dyeing, driven by the nozzle impact force, it circulates in the dyeing machine in the form of a rope-shaped fabric. In this process, the quality of fabric coloring is closely related to the twist of the fabric. If the twist of the fabric is too large during the running process, it will affect the infiltration and coloring of the dyeing assistant components in the dye liquor into the inner fabric, resulting in uneven fabric dyeing and poor dye uptake rate, seriously affecting the fabric dyeing quality and production efficiency.

[0004] Most of the traditional fabric untwisting devices are of fixed structure, and are limited by the structure of the dyeing machine and cannot be adjusted at any time, and cannot fully meet the dyeing treatment of various different types of fabrics and the untwisting effects required by different rules. It can be seen that there are many defects and deficiencies in the existing untwisting devices in the industry, and it is urgent to improve the device. Summary of the Utility Model

[0027] The following are specific embodiments of the present utility model and, in conjunction with the accompanying drawings, further describe the technical solutions of the present utility model. However, the present utility model is not limited to these embodiments.

[0028] Embodiment 1

[0029] As Figures 1 to 3 shown, an adjustable fabric untwisting device includes a housing assembly having a nozzle opening. The housing assembly is fixedly connected to a mounting seat 5 through a bracket 4. A driving assembly is rotatably connected to the mounting seat 5, and the driving assembly is telescopically connected to an adjusting assembly. The adjusting assembly extends into the nozzle opening to control the change of the aperture.

[0030] The housing assembly includes an annular body 1. A connecting pipe 2 communicating with the inner cavity of the annular body 1 is arranged on the outer periphery of the annular body 1. A U-shaped plate 3 is arranged inside the annular body 1. The inner pipe orifice of the connecting pipe 2 is connected to the U-shaped cavity of the U-shaped plate 3. The axis of the connecting pipe 2 is parallel to the center line of the U-shaped plate 3. The unobstructed part of the U-shaped cavity forms the nozzle opening. The outside space is communicated with the U-shaped cavity of the U-shaped plate 3 through the connecting pipe 2 to provide an installation space for other components. Through the relative position arrangement of the connecting pipe 2 and the U-shaped cavity, a guiding and assembling space is provided.

[0031] The bracket 4 includes bent rods that are symmetrically arranged left and right. One end of the bent rod is fixedly connected to the outer wall of the annular body 1, and the other end of the bent rod is fixedly connected to the outer wall of the mounting seat 5. The mounting seat 5 is arranged on the center line of the annular body 1. The main structure is symmetrically arranged left and right, thereby improving the stability and accuracy of equipment adjustment.

[0032] The driving assembly includes a crank. A lead screw 8 is fixedly penetrated inside the crank. The mounting seat 5 is provided with a mounting hole. A bearing 10 is installed in the mounting hole. A nut sleeve 9 is fixedly sleeved on the outer periphery of the lead screw 8. The nut sleeve 9 passes through the bearing 10 to form a rotational connection. The lead screw 8 passes through the mounting hole to form a driving screw segment.

[0033] The crank includes a seat body 6 and a handle 7 that are perpendicularly connected to each other. A connection hole is opened on the seat body 6 for passing through the lead screw 8. A screw is penetrated on the side wall of the connection hole, and the inner end of the screw fixes the lead screw 8. The handle 7 is vertically fixedly installed at the distal end of the seat body 6 through a bolt assembly. By holding the handle 7 with the hand to rotate the seat body 6 forward and backward, the seat body 6 synchronously drives the lead screw 8 and the nut sleeve 9 to rotate self, and the relative rotational movable connection is realized by using the bearing 10.

[0034] The adjusting assembly includes a threaded pipe 11 and a slider 12. The threaded pipe 11 is sleeved on the outer periphery of the driving screw segment to form a threaded meshing connection. The threaded pipe 11 penetrates through the connecting pipe 2 and extends into the U-shaped cavity of the U-shaped plate 3. A rotational connection is formed between the threaded pipe 11 and the connecting pipe 2. A joint is arranged at the extending end of the threaded pipe 11. A clamping groove is concavely arranged on the side of the slider 12. The joint is clamped into the clamping groove to form an axial fixed connection and a circumferential rotational connection. The slider 12 is embedded in the U-shaped cavity of the U-shaped plate 3 to form a sliding connection.

[0035] When the lead screw 8 rotates forward or backward, a clockwise or counterclockwise thread drive is formed through thread engagement. Since the slider 12 is restricted by the U-shaped cavity, the slider 12 moves forward or backward along the U-shaped cavity accordingly, thereby realizing the regulation of the nozzle orifice size.

[0036] The slider 12 is provided with a guiding inclined surface facing the U-shaped cavity, and the inclination angle of the guiding inclined surface is 60°. First, the guiding inclined surface can contact the rope-shaped fabric first, and through the impact action, the tension generated by the fabric due to the dyeing movement cycle is eliminated, so that the fibers of the fabric to be dyed are relaxed, and the shrinkage rates of the warp and weft are the same, ensuring the quality of the fabric and the dyeing effect.

[0037] A locking flange 13 is provided on the outer pipe orifice of the connecting pipe 2, and the locking flange 13 is detachably assembled with the outer pipe orifice of the connecting pipe 2 through bolts.

[0038] A scale plate 14 is provided between the mounting seat 5 and the locking flange 13, and the scale values on the scale plate 14 increase from the mounting seat 5 to the locking flange 13. After the lead screw 8 rotates to drive the threaded pipe 11 to move forward and backward, the value of the scale plate 14 aligned with the outer end of the threaded pipe 11 is the length of elongation of the threaded pipe 11, so as to display the position where the slider 12 enters the U-shaped cavity of the U-shaped plate 3, that is, the diameter of the nozzle orifice is obtained.

[0039] The operation mode of this adjustable fabric untwisting device is as follows:

[0040] As Figure 3 shown, when it is necessary to reduce the diameter of the nozzle orifice, rotate the crank in the forward direction to drive the lead screw 8 to rotate clockwise self-rotation. Through the thread engagement drive, the threaded pipe 11 is driven to push the slider 12 forward, so that the width between the slider 12 and the bottom edge of the U-shaped cavity becomes smaller.

[0041] As Figure 1 shown, when it is necessary to increase the diameter of the nozzle orifice, rotate the crank in the reverse direction to drive the lead screw 8 to rotate counterclockwise self-rotation. Through the thread engagement drive, the threaded pipe 11 is driven to pull the slider 12 backward, so that the width between the slider 12 and the bottom edge of the U-shaped cavity becomes larger.

[0042] When the rope-shaped fabric reaches the nozzle orifice, it impacts the guiding inclined surface of the slider 12, thereby eliminating the tension generated by the fabric due to the dyeing movement cycle, making the fibers of the fabric to be dyed relaxed, and the shrinkage rates of the warp and weft are the same, ensuring the quality of the fabric and the dyeing effect. After untwisting, the fabric passes through the nozzle orifice.
