Description

Technical Field

[0001] The utility model relates to the field of textiles, and particularly relates to a fabric weft deviation rectifying device, a warp rectifying machine, and a pattern and warp rectifying machine. Background Art

[0002] During the process of fabric transportation, deviation often occurs. Most of the existing fabric deviation rectifying devices are provided with a roller body, and a roller is rotatably installed on the roller body. During the transportation of the fabric, the fabric contacts the roller and drives the roller to rotate. When deviation rectification is required, deviation rectification is carried out through the inclined transportation of the roller. For example, in the patent application with the application number CN201610081427.8, it is this kind of structure.

[0003] For the deviation rectifying device with this kind of structure, during the rotation of the inclined roller, deviation rectification is realized through the frictional force between the roller surface of the roller and the fabric. However, for fabrics with relatively large warp tension, such as the fabrics in a warp rectifying machine, this kind of deviation rectifying mechanism simply cannot pull the fabric in the weft stretching direction of the fabric and cannot carry out deviation rectification. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a fabric weft deviation rectifying device which can well rectify the fabric, can well grasp the deviation rectifying amount, and is especially suitable for fabrics with large warp tension.

[0005] To solve the above technical problem, the technical solution of the utility model is: a fabric weft deviation rectifying device, comprising:

[0006] Two thorn shafts, distributed on both sides of the fabric along the weft direction of the transported fabric. Each thorn shaft includes a core shaft and at least one thorn ring. The thorn ring is rotatably installed on the core shaft, and a plurality of thorns are arranged on the circumferential surface. The thorns piercing into the fabric drive the thorn ring to rotate during the transportation of the fabric;

[0007] Two moving driving mechanisms, each moving driving mechanism is connected to a core shaft and is used to drive the core shaft to move in the weft direction of the fabric.

[0008] Further, in order to prevent the fabric from falling off the thorn ring during the process of the thorn shaft moving in the weft stretching direction, the... of the thorn ring.

[0009] Further, the included angle β between the central axis of the thorn ring and the central axis of the core shaft is 3° - 45°.

[0010] Further, in order to provide redundancy, at least two thorn rings are axially arranged along the core shaft.

[0011] Further, the included angle β between the central axes of all the thorn rings and the central axis of the mandrel is equal; or the included angles β between the central axes of at least two thorn rings and the central axis of the mandrel are not equal.

[0012] The specific structure of the moving drive mechanism is further provided, and the moving drive mechanism is a cylinder or a linear module or an electric push rod.

[0013] Further, the thorn shaft further includes at least one thorn ring seat, and each thorn ring is rotationally supported on the thorn shaft through a thorn ring seat.

[0014] The present utility model also relates to a warp straightening machine, including a fabric weft deviation correcting device.

[0015] The present utility model also relates to a pattern and warp straightening machine, including a fabric weft deviation correcting device.

[0016] After adopting the above technical solution, when the fabric is offset, the moving drive mechanism on the corresponding side drives the corresponding thorn shaft to move towards the fabric along the weft direction of the fabric. After the thorns on the thorn ring penetrate into the fabric, the thorn ring rotates driven by the fabric, and then the moving drive mechanism drives the thorn shaft to move in the stretching direction of the fabric weft, so that the deviation correction can be well realized. During the deviation correction process, the thorns penetrate into the fabric to prevent the fabric from falling off the thorn ring, and there is also a moving drive mechanism to assist the fabric to move in the stretching direction of the weft. Therefore, the deviation correcting device in the present utility model is particularly suitable for fabrics with large warp tension. Moreover, the present utility model can also control the displacement of the thorn shaft in the stretching direction of the fabric weft through the moving drive mechanism, so as to achieve the purpose of accurately controlling the deviation correction amount.

[0022] In order to make the content of the present utility model easier to be clearly understood, the present utility model will be further described in detail below according to specific embodiments and in conjunction with the drawings.

[0023] Embodiment 1

[0024] As shown in Figures 1 to 4 Figure [not shown], a fabric weft deviation correction device includes:

[0025] Two thorn shafts 1 are distributed on both sides of the fabric 2 along the weft direction of the conveyed fabric 2. Each thorn shaft 1 includes a core shaft 11 and at least one thorn ring 12. The thorn ring 12 is rotatably mounted on the core shaft 11, and a plurality of thorn needles 4 are arranged on the peripheral surface. The thorn needles 4 piercing into the fabric 2 are driven to rotate during the conveyance of the fabric 2;

[0026] Two moving drive mechanisms 3, each moving drive mechanism 3 is connected to a core shaft 11 for driving the core shaft 11 to move in the weft direction of the fabric 2.

[0027] Specifically, when the fabric 2 is offset, the corresponding moving drive mechanism 3 drives the corresponding thorn shaft 1 to move towards the fabric 2 along the weft direction of the fabric 2. After the thorn needles 4 on the thorn ring 12 pierce into the fabric 2, the thorn ring 12 is driven to rotate by the fabric 2, and then the moving drive mechanism 3 drives the thorn shaft 1 to move in the weft stretching direction of the fabric 2, so that the deviation correction can be well realized. During the deviation correction process, the thorn needles 4 pierce into the fabric 2 to prevent the fabric 2 from falling off the thorn ring 12, and there is the moving drive mechanism 3 to assist the fabric 2 to move in the weft stretching direction. Therefore, the deviation correction device in this embodiment is particularly suitable for fabrics 2 with large warp tension. And, the displacement of the thorn shaft 1 in the weft stretching direction of the fabric 2 can also be controlled by the moving drive mechanism 3 to achieve the purpose of accurately controlling the deviation correction amount.

[0028] In this embodiment, the thorn needles 4 can be steel needles. All the thorn needles 4 can be of equal length, or can be gradually lengthened along the axial direction of the thorn shaft 1 from the end close to the fabric 2 to the end far from the fabric 2.

[0029] For the thorn shaft 1, the thorn ring 12 is inclined towards the outside of the fabric 2 along the fabric conveying direction, which is the prior art and will not be elaborated here. Each thorn ring 12 is rotatably supported on the thorn shaft 1 by a thorn ring seat 13. In this embodiment, the included angle β between the central axis of the thorn ring 12 and the central axis of the core shaft 11 is 3° - 45°, preferably 12° - 21°, which is a relatively preferred angle through verification.

[0030] In this embodiment, as shown in Figures 1 to 4 Figure [not shown], at least two thorn rings 12 are axially arranged along the core shaft 11. During the normal conveyance of the fabric 2, it is preferably in contact with at least two thorn rings 12. Even if the fabric 2 falls off the outermost thorn ring 12, there are still the inner thorn rings 12 in contact with the fabric 2 to play a traction role on the fabric 2. Therefore, configuring at least two thorn rings 12 can provide a certain redundancy.

[0031] In this embodiment, the angle β between the central axis of each thorns ring 12 and the central axis of the core shaft 11 may be equal or unequal. In Figure 3 the thorns ring 11 shown, the angles β between the central axes of at least two thorns rings 12 and the central axis of the core shaft 11 are unequal.

[0032] In this embodiment, the moving drive mechanism 3 is a cylinder, a linear module or an electric push rod, and there is no limitation here. In Figure 1 and Figure 2 the moving drive mechanism 3 is a slide cylinder, and the slide cylinder is fixedly installed on the frame 5.
