Description

Technical Field

[0001] The utility model relates to the field of deviation-correcting devices, in particular to an intelligent deviation-correcting device for a transmission belt. Background Art

[0002] The two-for-one twister is a twisting device, which is essentially a doubling device (combining multiple strands into one strand) and is an important part of textile equipment.

[0003] In order to meet the needs of different textile production, one or more rows of guide wheels are provided on the two-for-one twisting machine. Multiple guide wheels in one row rotate synchronously through a transmission belt. During the friction between the transmission belt and the rotating shaft of the guide wheel, axial deviation will occur. If the transmission belt deviates from the axial center of the rotating shaft, it is easy to cause unstable transmission. Therefore, a correction device is required to promptly restore the transmission belt that has produced axial deviation to the axial center of the guide wheel rotating shaft. Utility Model Content

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-3 This application is described in further detail.

[0026] The embodiment of the present application discloses an intelligent deviation-correcting device for a transmission belt.

[0027] Reference Figure 1-3 The intelligent belt correction device includes a correction frame 1 and a correction wheel 2. The central axis of the correction wheel 2 is vertically arranged. The correction wheel 2 is rotatably arranged on the correction frame 1. The outer peripheral wall of the correction wheel 2 abuts against the transmission belt 3.

The upper edge 21 of the deviation correction wheel 2 can contact the upper side of the conveyor belt 3, and the lower edge 22 of the deviation correction wheel 2 can contact the lower side of the conveyor belt 3.

[0029] The deviation correction frame 1 is C-shaped. The upper plate 11 and the lower plate 12 of the deviation correction frame 1 are located on both sides in the width direction of the conveyor belt 3. The deviation correction frame 1 is arranged to swing up and down. A driving component 4 for driving the deviation correction frame 1 to swing is provided on the side of the deviation correction frame 1 away from the conveyor belt 3.

[0030] The driving component 4 includes a driving cylinder 41 and a cylinder bracket 42. The piston rod of the driving cylinder 41 is hinged to the deviation correction frame 1, and the cylinder body of the driving cylinder 41 is hinged to the cylinder bracket 42.

[0031] Two connecting plates 5 are provided at the bottom end of the middle plate 13 of the deviation correction frame 1. A connecting shaft 51 is provided between the two connecting plates 5. A connecting ring 52 is rotatably connected to the connecting shaft 51. The connecting ring 52 is connected to the piston rod of the driving cylinder 41. When the piston rod of the driving cylinder 41 extends, the lower plate 12 of the deviation correction frame 1 swings upward. When the piston rod of the driving cylinder 41 retracts, the upper plate 11 of the deviation correction frame 1 swings downward.

[0032] Two support plates 421 are provided on the side of the deviation correction frame 1 away from the conveyor belt 3. A connecting column 422 is provided between the two support plates 421. One support plate 421 corresponds to one connecting column 422. The connecting column 422 is fixedly connected to the support plate 421. A connecting sleeve 423 is provided between the two connecting columns 422. The connecting sleeve 423 is fixedly sleeved on the cylinder body of the driving cylinder 41. The connecting column 422 is rotatably connected to the connecting sleeve 423.

[0033] A support frame 6 is provided below the deviation correction frame 1. The support frame 6 is U-shaped. The bottom plate 61 of the support frame 6 is located on the workbench. A rotating shaft 63 is provided between the two side plates 62 of the support frame 6. The rotating shaft 63 passes through the middle plate 13 of the deviation correction frame 1 and is rotatably connected to the deviation correction frame 1. There is a space for the deviation correction frame 1 to swing between the lower plate 12 of the deviation correction frame 1 and the bottom plate 61 of the support frame 6.

[0034] A detection component 7 is provided beside the deviation correction frame 1. The detection component 7 includes a mounting plate 71. A first probe 72 and a second probe 73 are provided on the mounting plate 71 and are respectively located on both sides in the width direction of the conveyor belt 3. The first probe 72 is located above the second probe 73. The first probe 72 cooperates with the second probe 73 to detect the offset distance of the conveyor belt 3. The first probe 72 and the second probe 73 photograph the position of the conveyor belt 3. Both the first probe 72 and the second probe 73 are electrically connected to the driving cylinder 41.

[0035] Four correction frames 1 are arranged at intervals along the length direction of the transmission belt 3, and the correction frames 1 are staggered with the guide wheel 31. Each correction frame 1 corresponds to a correction wheel 2, and each correction frame 1 corresponds to a group of detection components 7. The first probe 72 and the second probe 73 on each mounting plate 71 are electrically connected to the adjacent driving cylinder 41 and control the stroke of the corresponding driving cylinder 41.

[0036] Each deviation-correcting frame 1 has a corresponding set of driving components 4 at its rear, and the piston rod strokes of the four driving cylinders 41 are different.

[0037] The first probe 72 of each detection component 7 cooperates with the second probe 73 to detect the upward or downward deviation of the transmission belt 3 and the distance between the transmission belt 3 and the axial center of the rotating shaft of the guide wheel 31. The first probe 72 of each detection component 7 cooperates with the second probe 73 to send the information of the upward or downward deviation of the transmission belt 3 and the distance between the transmission belt 3 and the axial center of the rotating shaft of the guide wheel 31 to the control system of each driving cylinder 41.

[0038] When the transmission belt 3 deflects upward, the piston rod of the driving cylinder 41 retracts, and when the transmission belt 3 deflects downward, the piston rod of the driving cylinder 41 extends.

[0039] The control system sets four offset intervals for the distance between the transmission belt 3 and the axial center of the guide wheel 31 shaft. Each offset interval corresponds to a driving cylinder 41, and the stroke of the piston rod of each driving cylinder 41 corresponds to an offset interval. When the distance between the transmission belt 3 and the axial center of the guide wheel 31 shaft reaches the corresponding offset interval of the driving cylinder 41, the piston rod of the corresponding driving cylinder 41 moves the corresponding stroke.

[0040] The implementation principle of the intelligent deviation-correcting device for a transmission belt in the embodiment of the present application is as follows:

[0041] The first probe 72 of the detection component 7 corresponding to each correction frame 1 cooperates with the second probe 73 to detect the upward or downward deviation of the transmission belt 3 and the distance between the transmission belt 3 and the axial center of the guide wheel 31 shaft, and sends the information of the upward or downward deviation of the transmission belt 3 and the distance between the transmission belt 3 and the axial center of the guide wheel 31 shaft to the control system of each driving cylinder 41. When the first probe 72 cooperates with the second probe 73 to detect that the transmission belt 3 is deflected upward, the piston rod of the corresponding driving cylinder 41 contracts, controls the upper edge 21 of the correction wheel 2 to swing downward and pushes the transmission belt 3 downward to the axial center of the guide wheel 31 shaft. When the first probe 72 cooperates with the second probe 73 to detect that the transmission belt 3 is deflected downward, the piston rod of the corresponding driving cylinder 41 extends, controls the lower edge 22 of the correction wheel 2 to swing upward and pushes the transmission belt 3 upward to the axial center of the guide wheel 31 shaft, and automatically and timely restores the transmission belt 3 that has axially deflected to the axial center of the guide wheel 31 shaft, thereby improving the transmission stability of the transmission belt 3.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
