Description

Technical Field

[0001] The utility model relates to deviation-correcting equipment, in particular to a deviation-correcting device with a flattening function. Background Art

[0002] During the fabric processing, the fabric needs to be guided by rollers so that the fabric can be transported along a predetermined path to meet the fabric processing requirements. During the fabric transportation process, the fabric may deviate to a certain extent, causing the fabric to twist during the transportation process, affecting the flatness of the fabric and the subsequent processing of the fabric.

[0003] Current fabric deviation correction equipment generally uses a deflection roller to achieve deviation correction. When the deviation correction roller is deflected, the fabric will be deflected in the wide direction, thereby achieving fabric deviation correction. In addition, some deviation correction equipment uses two upper and lower pressure rollers to press the fabric up and down, and the fabric deviation correction can also be achieved by moving the two pressure rollers.

[0004] The utility model proposes a new solution to solve the problem of cloth deviation correction. Utility Model Content

In addition, the two rollers can be independently driven to rotate by two drivers, and by adjusting the differential rotation of the two rollers, the forces exerted by the two rollers on the width direction of the fabric will differ, thereby correcting the deviation of the fabric.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] This embodiment discloses a deviation correction device with a flattening function. Figure 1 , 2 As shown, it includes a roller body 1 3, a roller body 2 4, a rotary drive 1 5 and a rotary drive 2 7; the roller body 1 3 and the roller body 2 4 are coaxially arranged, and the roller body 1 3 and the roller body 2 4 can rotate relative to each other around a common rotating shaft axis.

[0027] The outer parts of the roller body 1 3 and the roller body 2 4 are both provided with spiral parts, wherein the outer periphery of the roller body 1 3 is formed with a spiral part 1 32, and the outer periphery of the roller body 2 4 is formed with a spiral part 2 42. The parameters of the spiral part 1 32 and the spiral part 2 42 are substantially similar, and the rotation directions are opposite.

[0028] Roller body 1 3 and roller body 2 4 are assembled into a whole, and both spiral part 1 32 and spiral part 2 42 are spiral protrusion structures, and the rotation direction is opposite, forming a structure similar to a wire separation roller. Roller body 1 3 and roller body 2 4 have roughly the same outer diameter, and the parameters such as the pitch, protrusion height and spiral diameter of spiral part 1 32 and spiral part 2 42 are roughly the same, and only the rotation direction of the spiral part is opposite.

[0029] Reference Figure 4 As shown, when the cloth 9 passes through the spiral parts on the outer periphery of the roller body 1 3 and the roller body 2 4, the cloth 9 passes around the roller body 1 3 and the roller body 2 4 on both sides. The spiral part 1 32 on the outer periphery of the roller body 1 3 will contact with the surface of the cloth 9, generating a certain amount of extrusion. During the rotation process, the spiral part 1 32 will generate axial friction on the cloth 9, thereby generating a force on the cloth 9 in the direction opposite to the roller body 2 4; similarly, the spiral part 2 42 on the outer periphery of the roller body 2 4 will also generate axial friction on the cloth 9, thereby generating a force on the cloth 9 in the direction opposite to the roller body 1 3. Under the action of the roller body 1 3 and the roller body 2 4, the cloth 9 is expanded.

[0030] The rotary driver 15 can drive the roller 13 to rotate, and the rotary driver 27 can drive the roller 24 to rotate. The roller 13 and the roller 24 can be driven by two drivers respectively, and can realize independent rotation, and the roller 13 and the roller 24 can rotate relative to each other around the axis, so that the roller 13 and the roller 24 can form a rotation speed difference during the rotation process. The roller 13 and the roller 24 with different rotation speeds will generate a difference in the force on the cloth 9, and the two force differences will play a role in correcting the deviation of the cloth 9.

[0031] Reference Figure 3 As shown, the deviation correction device of this embodiment further includes an axis body 1, so that the axis body 1 can rotatably support the roller body 1 3 and the roller body 2 4, so that the roller body 1 3 and the roller body 2 4 can rotate independently around the axis body 1.

[0032] Specifically, the two ends of the shaft body 1 are supported and fixed by the support frame 2, and the roller body 1 3 and the roller body 2 4 are both hollow structures. The roller body 1 3 and the roller body 2 4 are both sleeved outside the shaft body 1 and rotatably connected to the outside of the shaft body 1. The roller body 1 3 and the shaft body 1 are rotationally supported by the bearing 1 31, and the roller body 2 4 and the shaft body 1 are rotationally supported by the bearing 2 41, so that the roller body 1 3 and the roller body 2 4 can rotate smoothly around the shaft body 1, and the roller body 1 3 and the roller body 2 4 can rotate relatively independently. The rotation support is realized by the shaft body 1 at the center of the roller body 1 3 and the roller body 2 4, which can maintain the rotation stability of the roller body 1 3 and the roller body 2 4.

[0033] The ends of roller body 1 3 and roller body 2 4 are close to each other, and a partition plate 11 is installed between roller body 1 3 and roller body 2 4. The partition plate 11 is a disc-shaped structure, installed between the ends of roller body 1 3 and roller body 2 4, and can separate roller body 1 3 and roller body 2 4 from each other, and can avoid contact interference between roller body 1 3 and roller body 2 4. The partition plate 11 can be fixedly connected to the outside of the rotating shaft, connected to the rotating shaft as an integral structure, and can rotate synchronously with the rotating shaft.

[0034] Specifically, the rotary driver 5 includes a rotating part 51, which can rotate and drive the roller body 3. The rotating part 51 has a through hole, is sleeved outside the shaft body 1, and is supported by a bearing for rotation between the rotating part 51 and the shaft body 1, so that it can rotate smoothly relative to the roller body. The rotating part 51 is coaxially installed with the roller body 3, and the rotating part 51 and the roller body 3 are rotated by a coupling 1, so that the roller body 3 can be driven to rotate through the coupling 1.

[0035] The structures of the rotary driver 1 5 and the rotary driver 2 7 are roughly the same and symmetrical. Specifically, the rotary driver 2 7 includes a rotary part 2 71, which can rotate and drive the roller body 2 4. The rotary part 2 71 has a through hole, is sleeved outside the shaft body 1, and is supported by a bearing for rotation between the rotary part 2 71 and the shaft body 1, so that it can rotate smoothly relative to the roller body. The rotary part 2 71 is coaxially installed with the roller body 2 4, and the rotary part 2 71 and the roller body 2 4 are rotated in linkage through the coupling 2, and the roller body 2 4 can be driven to rotate through the coupling 2.

[0036] The rotary driver 1 5 can be a motor, and the output end of the motor is the rotary part 1 51; similarly, the rotary driver 2 7 can also be a motor, and the output end of the motor is the rotary part 2 71. Alternatively, the rotary driver 1 5 and the rotary driver 2 7 can also be driven by other power, as long as they can achieve rotary drive.

[0037] Furthermore, the coupling 1 and the coupling 2 may adopt clutch couplings, namely clutch coupling 1 6 and clutch coupling 2 8. The clutch coupling can realize linkage between the corresponding rotating part and the corresponding roller body, and the clutch coupling can realize switching between the connection state and the separation state. Specifically, the clutch coupling can adopt an electromagnetic or other mechanical clutch structure.

[0038] Taking coupling 1 as an example, when coupling 1 is in a separated state, the rotating part 151 of the rotary driver 15 is separated from the roller body 13, the roller body 13 is not driven and can rotate freely around the shaft body 1, and the roller body 13 is passively rotated by the cloth 9; when coupling 1 is in a connected state, the rotating part 151 of the rotary driver 15 is connected to the roller body 13, and the rotary driver 15 can drive the roller body 13 to rotate actively.

[0039] During operation, the cloth 9 bypasses the outer periphery of the roller body 1 3 and the roller body 2 4, the coupling 1 and the coupling 2 are both in a separated state, and the roller body 1 3 and the roller body 2 4 are passively rotated by the bypassing of the cloth 9, and the spiral portion 1 32 outside the roller body 1 3 and the spiral portion 2 42 outside the roller body 2 4 can pull the cloth 9 in the wide direction, which can expand the cloth 9, thereby keeping the cloth 9 in a good flat state.

[0040] When the cloth 9 is in an offset state and needs to be corrected, the coupling 1 on one side will switch from a separated state to a connected state, and the corresponding rotary driver 1 5 on this side will drive the roller 1 3 on this side to actively rotate, so that a speed difference can be generated between the roller 1 3 and the roller 2 4, thereby causing a difference in the axial effects of the roller 1 3 and the roller 2 4 on the cloth 9, so that the cloth 9 can be offset along the axial direction of the roller body, thereby achieving cloth 9 correction.

[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
