Description

Technical Field

[0001] The utility model relates to the technical field of weftless fabric processing, in particular to a pre-flattening device for weftless fabric processing. Background Art

[0002] Weftless fabric, also known as weftless braided fabric, is a composite material made from ultra-high-strength, high-modulus fibers. The fibers are evenly laid using advanced high-tech equipment, impregnated with a high-strength elastomeric resin, bonded with a film, and then laminated using a 0° / 90° bi-orthogonal process. During the fabrication process, pre-flattening equipment is required to prevent wrinkles during subsequent cutting or processing, thereby improving the fabric's quality.

[0003] When using pre-flattening equipment, the fabric is pulled and transported by traction rollers, and then flattened by pressure rollers. However, when using this equipment, the pressure rollers are set perpendicular to the direction of movement of the fabric. The pressure rollers are not very effective in flattening the fabric, and even after flattening, small wrinkles may still appear, which will affect subsequent cutting or processing, resulting in poor performance. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figures 1-4 As shown, a pre-flattening device for processing non-woven fabrics includes a base 1, a conveying frame 2 is provided on the base 1, and a traction roller 3 is provided at the end of the conveying frame 2, a support platform 4 is provided at the middle part of the inner side of the conveying frame 2, and a fixed plate 5 is provided on the conveying frame 2, a lifting plate 7 is installed on the fixed plate 5 through a guide column 6, a lifting mechanism 8 is connected between the fixed plate 5 and the lifting plate 7, a flattening structure 9 is installed on the lower surface of the lifting plate 7, and the flattening structure 9 is inclined relative to the conveying frame 2, the flattening structure 9 is symmetrically arranged on the lower surface of the lifting plate 7, and the flattening structure 9 is located on the support platform 4. Above the conveyor frame 2, a reduction motor 10 is provided at one end, and the reduction motor 10 is connected to the traction roller 3. The lifting mechanism 8 includes a mounting plate 801, a servo motor 802, a follower plate 803, a nut seat 804 and a screw rod 805. The mounting plate 801 is fixed on the fixed plate 5, the servo motor 802 is installed on the mounting plate 801, the nut seat 804 is fixed on the follower plate 803, and the follower plate 803 is installed at the end of the lifting plate 7. The screw rod 805 is connected to the servo motor 802, and the screw rod 805 passes through the follower plate 803 and the nut seat 804.

[0020] When pre-flattening the weftless fabric, the pre-flattening equipment is stably placed by the base 1, and the weftless fabric is placed on the support platform 4 on the conveyor frame 2. After starting the reduction motor 10, the traction roller 3 runs to pull and convey the weftless fabric. During this process, the flattening structure 9 under the lifting plate 7 cooperates with the support platform 4 to pre-flatten the weftless fabric. Since the two flattening structures 9 are arranged at an angle, the flattening structure 9 not only flattens the weftless fabric, but also applies a force to the weftless fabric to expand toward both sides, which can improve the flattening effect of the weftless fabric. When necessary, the height of the flattening structure 9 can be adjusted. When adjusting, the servo motor 802 on the mounting plate 801 is started, and the servo motor 802 drives the screw rod 805 to rotate the arm, thereby applying a force to the nut seat 804 on the follower plate 803, causing the nut seat 804 to rise and fall, and the follower plate 803 applies a force to the lifting plate 7, causing the lifting plate 7 to move along the guide column 6 on the fixed plate 5, thereby changing the height of the flattening structure 9, which has high flexibility in use.

[0021] According to the above embodiment, the flattening structure 9 includes a roller frame 901, a mounting seat 902, a flattening roller 903, an end head 904 and an elastic mounting assembly 905. The mounting seat 902 is fixed on the roller frame 901, the flattening roller 903 is rotatably mounted on the mounting seat 902, the end head 904 is fixed to the end of the roller frame 901, and the end head 904 is connected to the elastic mounting assembly 905. The elastic mounting assembly 905 includes a mounting frame 9051, a mounting bolt 9052, a connecting bolt Rod 9053, spring 9054, threaded rod 9055 and limit block 9056, the mounting frame 9051 is fixed to the lower surface of the lifting plate 7 by the mounting bolt 9052, and the mounting frame 9051 is provided with a through hole, the connecting rod 9053 is fixed to the end 904, and the connecting rod 9053 passes through the mounting frame 9051, the spring 9054 is sleeved on the connecting rod 9053, and the spring 9054 is located between the end 904 and the mounting frame 9051, the threaded rod 9055 is fixed The cam 9054 is fixed on the spring 9054, and the threaded rod 9055 passes through the through hole on the mounting frame 9051, and the limit block 9056 is threadedly connected to the threaded rod 9055. Through the two sets of flattening structures 9, the flattening structure 9 is relatively inclined. In the process of the traction roller 3 moving with the cloth, the flattening roller 903 in the flattening structure 9 produces an oblique force on the cloth, thereby effectively performing the pre-flattening of the non-weft cloth, improving the pre-flattening effect, preventing the occurrence of unflattened parts, and ensuring the effect of subsequent processing. The elastic mounting assembly 905 is used to install the entire flattening structure 9. After installation, during the flattening process, the end head 904 can be raised and lowered on the mounting frame 9051 by the spring 9054 and the connecting rod 9053, and the flattening roller 903 on the roller frame 901 can be moved to flatten the non-weft cloth with increased stacking thickness, thereby preventing the non-weft cloth from being stuck due to its large stacking thickness, and having higher flexibility and adaptability in use.

[0022] When installing the flattening structure 9, the flattening roller 903 is installed between the mounting seats 902 on the roller frame 901, and the mounting frame 9051 is fixed to the lower surface of the lifting plate 7 by using the mounting bolts 9052, thereby completing the installation of the entire flattening structure 9. During the flattening process, the traction roller 3 moves with the non-woven fabric. Under the action of the non-woven fabric, the flattening roller 903 rotates on the mounting seat 902. At the same time, the inclined flattening roller 903 applies an oblique force to the non-woven fabric, so that the non-woven fabric will unfold to both sides while moving forward, thereby improving the flattening effect. If a thicker stack of non-woven fabric is encountered, after the flattening roller 903 is pressed onto the non-woven fabric, the end 904 The force moves the connecting rod 9053 upward, and the threaded rod 9055 and other structures move upward. At the same time, the spring 9054 is compressed, and the flattening roller 903 gives way to press the non-weft cloth normally without getting stuck. After the stacking area is removed, under the action of the spring 9054 and gravity, the roller frame 901 and the flattening roller 903 descend until the limit block 9056 contacts the mounting frame 9051 and stops, and then the flattening process can be continued. When necessary, the limit block 9056 on the threaded rod 9055 can be rotated to change the relative position of the end 904 and the mounting frame 9051, thereby changing the compression state of the spring 9054, and it has high adaptability.
