Detailed Implementation

[0035] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0036] Example 1

[0037] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, a high-damping weft bend straightening and weft alignment machine includes:

[0038] 1. A frame, at least one curved roller 2, and at least one straight roller 3 for correcting weft skew in the fabric; wherein,

[0039] The curved roller 2 and the straight roller 3 are respectively rotatably mounted on the frame 1;

[0040] The bending roller 2 is used to correct the weft bending of the fabric, and at least one bending roller 2 is provided with a damping mechanism 4 for applying damping to the rubber sleeve 21 thereof.

[0041] The inventor of the patent finds that the weft straightener with the rubber sleeve 21 of the bending roller 2 passively rotating has a poor weft bending correction effect on the fabric mentioned in the background art which is difficult to straighten, because the bending roller 2 only relies on its own curvature to correct the weft bending, and the correction force is not enough, so the fabric is easy to rebound. Based on this finding, the damping mechanism 4 is arranged on the rubber sleeve 21 of at least one bending roller 2. After the damping mechanism 4 is arranged, the curvature of the bending roller 2 is superimposed with the damping of the passive rotation of the rubber sleeve 21 of the bending roller 2, and the two work together to correct the weft bending of the fabric, thereby avoiding the rebound of the fabric after correction, such as heavy weight fabric, high elasticity fabric and loose weave fabric, and the correction effect is relatively good.

[0042] The damping mechanism 4 is a clutch, which can be an electromagnetic clutch, a pneumatic clutch, a magnetic powder clutch brake 4a, etc., and is preferably a magnetic powder clutch brake 4a. Figure 1 Figure 2 The magnetic powder clutch brake 4a is shown.

[0043] In the embodiment, as shown in Figure 1 Figure 2 The bending roller 2 has two, and the rubber sleeves 21 of the two bending rollers 2 are drivingly connected, and the rubber sleeve 21 of one of the two bending rollers 2 is drivingly connected with the output end of the magnetic powder clutch brake 4a. In this way, damping is applied to the rubber sleeves 21 of the two bending rollers 2 simultaneously by one magnetic powder clutch brake 4a. As shown in Figure 1 Figure 2 The rubber sleeve 21 of each bending roller 2 is provided with a bending roller pulley 5, and the output end of the magnetic powder clutch brake 4a is provided with a clutch pulley 6; the two bending roller pulleys 5 are drivingly connected by a belt 7, and the clutch pulley 6 is drivingly connected with one of the bending roller pulleys 5 by the belt 7.

[0044] It should be noted that one magnetic powder clutch brake 4a can also be arranged for each bending roller 2, and the number of bending rollers 2 is not limited thereto, and one, three, etc. can also be arranged as needed.

[0045] In the embodiment, as shown in Figure 7 Figure 8 The bending roller 2 can include, but is not limited to, an arc-shaped roller core 22, a rubber sleeve 21 and a plurality of sleeves 23; the arc-shaped roller core 22 is rotatably installed on the rack 1; the plurality of sleeves 23 are arranged along the axial direction of the arc-shaped roller core 22, and are all rotatably installed on the arc-shaped roller core 22 through internal bearings 24; the rubber sleeve 21 is sleeved outside all the sleeves 23. The connection mode between the rubber sleeve 21 and the bending roller pulley 5 can be, but is not limited to, that one connecting sleeve connects the rubber sleeve 21 through a connecting piece, and the bending roller pulley 5 is sleeved on the connecting sleeve. ​​​​

[0046] In the embodiment, as shown in Figure 1 The weft straightener further comprises a power mechanism 8 connected with the arc-shaped roller core 22 to drive the rotation of the arc-shaped roller core 22. The power mechanism 8 is a prior art, which can comprise a motor and a speed reducer, the motor and the speed reducer are respectively installed on the frame 1, the output shaft of the motor is connected with the input shaft of the speed reducer, and the output shaft of the speed reducer is connected with the arc-shaped roller core 22 of the bending roller 2 through a chain transmission, so as to drive the rotation of the arc-shaped roller core 22. In the case that two bending rollers 2 are provided, the arc-shaped roller cores 22 of the two bending rollers 2 can also be driven through a chain transmission. This is a prior art, and will not be described in detail.

[0047] Embodiment Two

[0048] As shown in Figure 3 and Figure 4 The main difference between the embodiment and the embodiment one is that the damping mechanism 4 is replaced by a motor-generator dual-purpose device 4b capable of generating electricity by active rotation and passive rotation.

[0049] In this way, the motor-generator dual-purpose device 4b can generate electricity by passive rotation to apply damping to the rubber sleeve 21 of the bending roller 2, and can also actively rotate to drive the rotation of the rubber sleeve 21 of the bending roller 2 by being electrified, so that the weft straightener has two working modes, and can be switched between the two working modes very conveniently, and has strong versatility.

[0050] In the embodiment, as shown in Figure 3 and Figure 4 In the case that two bending rollers 2 are provided, the rubber sleeves 21 of the two bending rollers 2 are drivingly connected, and the rubber sleeve 21 of one of the bending rollers 2 is drivingly connected with the shaft of the motor-generator dual-purpose device 4b. The specific driving mode can be that the rubber sleeve 21 of each bending roller 2 is provided with a bending roller pulley 5, the shaft of the motor-generator dual-purpose device 4b is provided with a device pulley, the two bending roller pulleys 5 are drivingly connected through a belt 7, and the device pulley and one of the bending roller pulleys 5 are drivingly connected through the belt 7.

[0051] As shown in Figure 3 and Figure 4 When the distance between the device pulley and the bending roller pulley 5 is relatively far, a transmission pulley 9 can be rotatably installed at a position between the device pulley and the bending roller pulley 5 on the frame 1 as a transition, and the device pulley and one of the bending roller pulleys 5 are drivingly connected with the transmission pulley 9 through the belts 7.

[0052] Embodiment Three

[0053] As shown in Figure 5 and Figure 6As shown, the main difference between the embodiment and the embodiment one is that the damping mechanism 4 comprises a clutch and a motor generator dual-purpose device 4b capable of driving rotation and passive rotation to generate electricity after being powered.

[0054] As shown, Figure 7 and Figure 8 The magnetic powder clutch brake 4a and the motor generator dual-purpose device 4b are respectively connected with the same bending roller 2.

[0055] In this way, the damping applied to the rubber sleeve 21 of the bending roller 2 by the magnetic powder clutch brake 4a and the motor generator dual-purpose device 4b can be adjusted simultaneously, so that the damping applied has a larger adjustment range and meets various requirements.

[0056] Of course, in the case of removing the transmission between the magnetic powder clutch brake and the bending roller 2 or adjusting the damping applied by the magnetic powder clutch brake to the minimum, the motor generator dual-purpose device 4b can also be used as a motor to drive the rubber sleeve 21 of the bending roller 2 to rotate actively, meeting more types of requirements.

[0057] Based on the above ideal embodiments according to the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content of the specification, and must be determined according to the scope of the claims.
