Description

Technical Field

[0001] This utility model relates to the field of material edge spreading and expansion technology, specifically to an edge spreading and expansion device. Background Technology

[0002] Edge spreading and width expansion involves unfolding or widening the material. This is generally achieved by increasing the lateral tension of the material through mechanical action, in order to achieve the purpose of edge spreading or wrinkle prevention, in order to meet the needs of the production process.

[0003] Existing edge-expanding devices are generally either threaded edge-expanding devices or bending roller edge-expanding devices. The advantages and disadvantages of these two devices are as follows:

[0004] 1. Threaded edge spreading and expansion device: The roller is symmetrically engraved with oblique groove threads from the center direction. The oblique groove threads have a certain angle with the axis. The material is spread by the friction generated on both sides of the threaded edge spreading roller when the material passes through it.

[0005] The device has a simple structure and low cost, but the angle of edge expansion is fixed, and it is easy to scratch the material during the edge expansion process, and it is easy to leave thread marks on the material during the edge expansion process.

[0006] 2. Bending Roller Edge Expanding Device: The bending roller is an arc-shaped roller made of elastic rubber, with both ends fixed and the roller body having an arc-shaped protrusion. When the material moves tightly against the roller surface under pressure, the bending roller rotates around its arc axis due to the friction between the material and the roller surface. The material is subjected to unevenly distributed friction in the weft direction (transverse direction), forming a tension gradient that increases from the center to both sides, thereby achieving edge expansion.

[0007] The device has a simple structure and low cost, but the angle of the expansion is fixed and cannot adapt to different expansion ratios. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides an edge-expanding device. The edge-expanding ratio is adjusted by two rotating seats with adjustable rotation angles. Each rotating seat is equipped with two pairs of upper and lower clamping tracks that can clamp the material while ensuring that the material is not scratched.

[0009] This utility model provides the following technical solution:

[0010] An edge-expanding device includes a bottom support plate, a rotating base, a track, and a motor;

[0011] Two rotating seats are symmetrically arranged on the bottom support plate, and the rotation angle of each rotating seat can be adjusted according to actual needs;

[0012] Each of the rotating seats is provided with two pairs of upper and lower clamping tracks to clamp the opposite sides of the material to be expanded.

[0013] Each pair of tracks is equipped with a motor to drive the tracks independently.

[0014] Furthermore, the upper tracks of the two pairs of tracks on the same rotating base are at the same height, and the lower tracks of the two pairs of tracks on the same rotating base are at the same height.

[0015] Furthermore, the track is a flexible rubber track.

[0016] Furthermore, the track surface is provided with a silicone protective layer.

[0017] Furthermore, the thickness of the silicone protective layer is 0.5mm to 5mm.

[0018] Furthermore, the rotating seat includes a side plate, a bottom plate, and two support plates for supporting the side plate and the bottom plate. The track is disposed on the side plate, and the bottom plate is fixed on the bottom support plate.

[0019] Furthermore, the base plate of the rotating seat is provided with two arc-shaped grooves for adjusting the rotation angle of the rotating seat, and the two arc-shaped grooves are arranged concentrically.

[0020] Furthermore, the angle adjustment range of the arc-shaped groove is 5° to 30°.

[0021] Furthermore, the driving speed of the motor is adjusted according to the linear speed of the material production line.

[0022] Furthermore, the driving speed of the motor is also adjusted according to the rotation angle of the rotating base.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] The material is clamped by the upper and lower clamping track to ensure that the material does not loosen. At the same time, the track is a flexible rubber track with a silicone protective layer on the track surface to prevent the material from being scratched when the edge is expanded.

[0025] Each pair of upper and lower clamping tracks is equipped with a motor. The motor's drive speed is adjustable and tracks and matches the linear speed of the customer's production line, thereby preventing material breakage or accumulation due to speed mismatch.

[0026] The base plate of the rotating seat is equipped with an arc groove, which can adjust the angle of the material's edge expansion to meet the requirements of different processes and different edge expansion ratios. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings:

[0034] This embodiment provides an edge-stretching and width-expanding device, the overall structure of which is as follows: Figure 1 , Figure 2 As shown, the device includes a bottom support plate 1, a rotating seat 2, a track 3, and a motor 4.

[0035] Two rotating seats 2 are symmetrically arranged on the bottom support plate 1, and the rotation angle of each rotating seat 2 can be adjusted according to actual needs.

[0036] The specific structure of the rotating seat 2: The rotating seat 2 includes an L-shaped side plate 21 and a bottom plate 23, as well as two support plates 22 for supporting the side plate 21 and the bottom plate 23. The side plates 21 of the two rotating seats 2 are provided with opposing tracks 3. The bottom plate 23 is provided with concentric arc-shaped grooves 24. The bottom plate 2 is fixed to the bottom support plate 1 by bolts passing through the arc-shaped grooves 24 and threaded holes on the bottom support plate 1. After loosening the bolts, rotating the rotating seat 2 can adjust the installation angle of the rotating seat 2 on the bottom support plate 1. The position of the arc-shaped grooves 24 on the bottom plate 23 is as follows: Figure 3 As shown.

[0037] The angle adjustment range of the arc groove 24 is 5° to 30° to adapt to the edge expansion requirements of different materials and processes.

[0038] To clamp the material 5 securely during actual use and prevent it from shifting, each rotating seat 2 is equipped with two pairs of upper and lower clamping tracks 3. The opposite sides of the material 5 are clamped between the upper and lower clamping tracks 3 on both sides. The actual operating state of the device is as follows: Figure 4 As shown.

[0039] Furthermore, in order to protect the material during the expansion of the edge and prevent the material from being scratched by the device, the track 3 is a flexible rubber track, and a silicone protective layer is provided on the surface of the track 3, with a thickness of 0.5mm to 5mm.

[0040] Furthermore, in order to prevent the material from stacking between the two pairs of tracks 3, to prevent the material from wrinkling when expanding the edge, and to further ensure the stability of the material clamping, the upper tracks 31 of the two pairs of tracks 3 on the same rotating seat 2 are at the same height, and the lower tracks 31 of the two pairs of tracks 3 on the same rotating seat 2 are at the same height.

[0041] Each pair of tracks 3 is equipped with a motor 4 to independently drive the track 3, and the driving speed of each motor 4 is adjusted according to the linear speed of the material production line. The device is set after the production line to expand the edges of the produced material. Each motor 4 tracks and matches the linear speed of the customer's production line, thereby preventing material breakage or accumulation due to speed mismatch. At the same time, the speed of each motor 4 can also be finely adjusted according to the rotation angle of the rotating seat 2 in actual production to prevent wrinkles from occurring in the material during edge expansion.
