Description

Technical Field

[0001] The utility model relates to the technical field of tire production equipment, in particular to a fabric take-up and spreading roller device. Background Art

[0002] At the fabric guiding and unwinding station, the fabric unwound from the fabric roll is wound onto the fabric roll after being reversed by the reversing roller, while the fabric unwound from the fabric roll is conveyed backward above the fabric roll. Since the reversing roller is a smooth roller, the fabric is prone to wrinkling during winding. The wrinkles on the surface of the fabric roll will affect the fabric conveyed backward above it, causing it to deform, and further affecting the subsequent cutting.

[0003] Therefore, there is an urgent need to design a spreading roller device that can be adjusted according to the state of the fabric. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fabric take-up and spreading roller device for the defects existing in the prior art.

[0005] The technical solution of the utility model is: a fabric take-up and spreading roller device, including a smooth roller and two spreading rollers. The smooth roller and the two spreading rollers are arranged in a circumferential array, and the ends of the three are connected by a connecting plate, and the ends of the three are rotatably installed on the connecting plate; at the centers of the outer walls of the two connecting plates, there are horizontal rotating shafts, the rotating shafts are rotatably installed on the frame, and the connecting plates are drivingly connected with a driving component for driving the connecting plates to rotate.

[0006] Preferably, the connecting plate is a disc.

[0007] Preferably, the two groups of driving components are symmetrically arranged and include cylinders; the cylinder body of the cylinder is hinged on the frame, and the end of the cylinder rod is hinged on the edge of the outer wall of the disc.

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] The device has a simple structure and strong practicability, and can switch the contact roller according to the states of the fabric and the curtain fabric; the device can make the fabric winding more stable, effectively reduce the phenomena of folding and poor winding, so as to stabilize the width of the curtain fabric and make the cutting stable. Brief Description of the Drawings

[0010] Figure 1 is a three-dimensional structural schematic diagram of the utility model;

[0011] Figure 2 is a schematic diagram of the use state of the utility model.

[0012] In the figure: 1, frame; 2, cord fabric roll; 3, backing fabric roll; 4, cord fabric; 5, backing fabric; 6, light roller; 7, fabric spreading roller; 8, disc; 9, rotating shaft; 10, air cylinder. Detailed implementation mode

[0013] The following further describes the present utility model in conjunction with the accompanying drawings and embodiments. Embodiment 1

[0014] Referring to Figure 1-2 As shown, a device for winding and spreading the backing fabric 5 on the fabric spreading roller 7 includes a light roller 6 and two fabric spreading rollers 7. The light roller 6 and the two fabric spreading rollers 7 are arranged in a circumferential array, and the ends of the three are connected by a connecting plate, and the ends of the three are rotatably installed on the connecting plate; horizontal rotating shafts 9 are provided at the centers of the outer walls of the two connecting plates, the rotating shafts 9 are rotatably installed on the frame 1, and the connecting plate is drivingly connected with a driving assembly for driving the connecting plate to rotate.

[0015] More specifically, the connecting plate is a disc 8.

[0016] The two groups of driving assemblies are symmetrically arranged, and each includes an air cylinder 10; the cylinder body of the air cylinder 10 is hinged on the frame 1, and the end of the rod of the air cylinder 10 is hinged on the edge of the outer wall of the disc 8.

[0017] During use, it is necessary to ensure that the two rollers are located below to keep in contact with the backing fabric 5, and the disc 8 is driven to rotate by the air cylinder 10, so as to switch the three rollers; in the normal state, the backing fabric 5 is wound stably. At this time, the light roller 6 and one fabric spreading roller 7 are located below. The backing fabric 5 exported from the cord fabric roll 2 first contacts the light roller 6, then contacts the fabric spreading roller 7, and finally is wound onto the backing fabric roll 3; when the winding of the backing fabric 5 is poor and wrinkles appear, the air cylinder 10 is started, and the rod of the air cylinder 10 extends to drive the disc 8 to rotate counterclockwise, so as to turn the two fabric spreading rollers 7 to the lower part to contact the backing fabric 5. Subsequently, the two fabric spreading rollers 7 spread the backing fabric 5 successively, so as to eliminate the wrinkles of the backing fabric 5, weaken the phenomenon of poor winding, and further stabilize the width of the cord fabric 4, making the cutting stable.

[0018] The structure of this device is simple and has strong practicability. The contact rollers can be switched according to the states of the backing fabric 5 and the cord fabric 4; this device can make the winding of the backing fabric 5 more stable, effectively reduce the phenomena of wrinkling and poor winding, and thus can stabilize the width of the cord fabric 4 and make the cutting stable.

[0019] The present utility model is not limited to the above-mentioned implementation modes. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present utility model, and the changed content still belongs to the protection scope of the present utility model.
