Description

Technical Field

[0001] The utility model belongs to the technical field of textile processing, and particularly relates to a drafting device applicable to textile processing. Background Technique

[0002] In the textile process, processes such as drawing and drafting are required. At present, when drafting yarn, a drafting device is usually used to draw the yarn thinner, and at the same time improve the straightness parallelism and separation degree of the fibers in the sliver. Specifically, drafting is the process of stretching and thinning the carded sliver, gradually straightening the fibers therein, gradually eliminating the hooks, and at the same time gradually making the sliver reach the predetermined thickness. During drafting, the fibers are gradually drawn out from the surrounding fiber group one by one. Due to mutual friction, the hooks are gradually eliminated and the curls are gradually straightened. This is achieved through fiber control and speed change. In this way, the transverse connection remaining inside each fiber may be completely eliminated, creating conditions for firmly establishing a regular head-to-tail connection relationship.

[0003] However, the existing drafting devices cannot effectively monitor the drafting force of the yarn, nor can they perform drafting adjustment when the yarn is slack. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a drafting device applicable to textile processing.

[0005] To achieve the above technical purpose, the technical scheme adopted by the utility model is as follows:

[0006] A drafting device applicable to textile processing includes a tension sensor for detecting the drafting force of the yarn, and a guide wheel for adjusting the tightness of the yarn is arranged at the position between the tension sensors;

[0007] The guide wheel is rotatably connected with a slider, the slider is slidably matched with a guide rod, the midpoint connection line of the two tension sensors is recorded as a reference line, the guide rod is perpendicular to the reference line, and the slider only has the freedom to move axially along the guide rod;

[0008] One end of the guide rod is fixedly connected with a mounting plate, a spring is sleeved outside the guide rod, and the spring is distributed at the position between the mounting plate and the slider;

[0009] Both ends of the spring are connected with end plates, the mounting plate is connected with a pressure sensor, and the pressure sensor abuts against the end plate on the side close to the mounting plate;

[0010] The slider is connected with a telescopic power source through a bracket.

[0011] Further defined, it also includes a controller. With such a structural design, the controller is used for signal processing, specifically including signal processing and control of the tension sensor, pressure sensor, and telescopic power source.

[0012] Further defined, the telescopic power source selects an electric telescopic rod. With such a structural design, the electric telescopic rod is more convenient to control.

[0013] Further defined, the bracket is provided with a main board. One side of the main board is provided with a connector for connecting to the electric telescopic rod, and the other side of the main board is provided with a connecting rod for connecting to the slider. With such a structural design, the connector is used to connect to the electric telescopic rod, and the connecting rod is used to connect to the slider.

[0014] Further defined, the end plate near the pressure sensor is provided with a convex column. The mounting plate is provided with a through hole for mounting the pressure sensor. The convex column penetrates into the through hole and abuts against the pressure sensor. With such a structural design, the convex column serves as a concentrated force transfer point, which can concentrate the elastic force from the spring received by the end plate and transfer it to the pressure sensor, avoiding the dispersion of force due to contact with other objects during the force transfer process and enabling accurate measurement of the elastic force magnitude.

[0015] Advantages of the present utility model:

[0016] 1. It can realize the adjustment of the yarn, so that the drafting force is always within the specified range, ensuring the quality of yarn drafting;

[0017] 2. It can realize the measurement of the adjustment distance, and then reflect the magnitude of the adjustment amplitude of the yarn each time. Description of the drawings

[0033] Embodiment

[0034] As Figures 1-3 shown, this embodiment provides a drafting device applicable to textile processing, including a tension sensor 1 for detecting the drafting force of the yarn, and a guide wheel 2 for adjusting the tightness of the yarn is arranged at the position between the tension sensors 1;

[0035] The guide wheel 2 is rotatably connected to the slider 3, the slider 3 is slidably matched with the guide rod 4, the midpoint connection line of the two tension sensors 1 is recorded as the reference line, the guide rod 4 is perpendicular to the reference line, and the slider 3 only has the freedom to move axially along the guide rod 4;

[0036] One end of the guide rod 4 is fixedly connected to the mounting plate 8, a spring 7 is sleeved outside the guide rod 4, and the spring 7 is distributed at the position between the mounting plate 8 and the slider 3;

[0037] Both ends of the spring 7 are connected to the end plate 71, the mounting plate 8 is connected to the pressure sensor 9, and the pressure sensor 9 abuts against the end plate 71 on the side close to the mounting plate 8;

[0038] The slider 3 is connected to the telescopic power source 5 through the bracket 6.

[0039] In this embodiment:

[0040] The yarn to be drafted is wound around the tension sensor 1 and the guide pulley 2 in sequence. When drafting, the tension sensor 1 is responsible for detecting the force on the yarn, and the guide pulley 2 is responsible for the tightness of the yarn.

[0041] When the tension sensor 1 detects that the force on the yarn does not match the specified drafting force, the guide pulley 2 adjusts its position, thereby making the yarn taut or loose. Specifically, the position adjustment of the guide pulley 2 is realized by the telescopic power source 5. The telescopic power source 5 transmits the power to the slider 3 through the bracket 6. The slider 3 moves linearly under the restriction of the guide rod 4, and then drives the guide pulley 2 to move. The movement of the guide pulley 2 will change the drafting state of the yarn. While the yarn changes its state, the magnitude of the force detected by the tension sensor 1 also changes accordingly. When the value is within the specified drafting force range, the telescopic power source 5 stops moving and keeps the position of the slider 3 fixed.

[0042] While the slider 3 moves along the guide rod 4, the slider 3 will also compress or release the spring 7, and the elastic force of the spring 7 will change. Since the elastic coefficient of the spring 7 remains unchanged, therefore, through the pressure difference change measured by the pressure sensor 9, the deformation amount of the spring 7 can be indirectly obtained. The amount of this deformation characterizes the moving distance of the slider 3. This structure realizes the measurement of the adjustment distance and can reflect the magnitude of each adjustment of the yarn.

[0043] Preferably, a controller is further included. With such a structural design, the controller is used for signal processing, specifically including signal processing and control of the tension sensor 1, the pressure sensor 9, and the telescopic power source 5. In fact, other control structures can also be specifically considered according to specific situations.

[0044] Preferably, the telescopic power source 5 is selected as an electric telescopic rod. With such a structural design, the electric telescopic rod is more convenient for control. In fact, other types of the telescopic power source 5 can also be specifically considered according to specific situations.

[0045] Preferably, the bracket 6 is provided with a main board 61. One side of the main board 61 is provided with a joint 63 for connecting with the electric telescopic rod, and the other side of the main board 61 is provided with a connecting rod 62 for connecting with the slider 3. With such a structural design, the joint 63 is used for connecting with the electric telescopic rod, and the connecting rod 62 is used for connecting with the slider 3. In fact, other structural shapes for connecting the power between the telescopic power source 5 and the slider 3 can also be specifically considered according to specific situations.

[0046] Preferably, the end plate 71 on the side close to the pressure sensor 9 is provided with a convex post 72, and the mounting plate 8 is provided with a through hole for mounting the pressure sensor 9. The convex post 72 penetrates into the through hole and abuts against the pressure sensor 9. With such a structural design, the convex post 72 serves as a concentrated force transfer point, which can concentrate the elastic force from the spring 7 received by the end plate 71 and transfer it to the pressure sensor 9, avoiding the dispersion of force due to contact with other objects during the force transfer process and making it impossible to accurately measure the magnitude of the elastic force. In fact, other structural shapes that can avoid the dispersion of the elastic force can also be considered according to specific circumstances.

[0047] The above embodiments merely exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person skilled in the art of this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention.
