Description

Technical Field

[0001] This utility model relates to a textile equipment, specifically, to a textile fabric leveling device. Background Technology

[0002] During the printing and dyeing process, fabrics often require soaking, rinsing, and dehydration. After dehydration, the fabric easily twists into a rope-like structure. Before proceeding to the next processing step, a detwisting and unfolding machine is needed to unfold the rope-like fabric into a sheet. For example... Figure 1 As shown, a traditional untwisting and opening machine mainly consists of a feeding mechanism 1, an untwisting mechanism 2, an opening mechanism 3, and an output mechanism 4. The feeding hopper 5 holds rope-like fabric, which is guided into the untwisting mechanism 2 by the feeding mechanism 1. The untwisting mechanism 2 uses counter-rotating rollers to untwise the fabric. A beating mechanism 7 is set at the connection between the untwisting mechanism 2 and the opening mechanism 3. The beating mechanism 7 has 2-3 arc-shaped rods around a central rotating shaft. As the central rotating shaft rotates, the arc-shaped rods intermittently beat the untwisted fabric, causing it to gradually unfold. The fabric enters the opening mechanism 3 and passes through multiple rollers with bidirectional spiral patterns on their surfaces, gradually flattening it. Finally, the reciprocating swing of the output mechanism 4 stacks the flattened material into the receiving hopper 6.

[0003] When the twist of textile fabric is large, the existing beating mechanism does not provide a high degree of unfolding. Directly entering the opening mechanism can easily cause folding on the conveyor rollers, affecting the flattening effect and the stability of the equipment operation. To this end, a paper with application number 201821537093.1 discloses an opening machine, which can blow air towards the fabric while beating it by opening an air outlet on the secondary shaft (i.e., the arc-shaped rod). Since the airflow is also arc-shaped, it can further blow open the two sides of the fabric, increase the opening width at this position, facilitate the subsequent processing of the opening mechanism, and is suitable for untwisting operations of fabrics with large twist. However, it has the following disadvantages: (1) If the airflow is too small, it is not easy to blow open the fabric; if the airflow is too large, it is easy to blow the fabric away, resulting in the secondary shaft not being able to hit it, which is difficult to control; (2) It requires a large modification to the existing beating mechanism and the structure is relatively complex.

[0004] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a scientifically designed textile fabric leveling device that offers excellent flattening effects for fabrics with high twist, has a simple structure, and is highly practical.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a textile fabric leveling device, comprising a de-twisting mechanism, a width-opening mechanism, and a beating mechanism connected between the de-twisting mechanism and the width-opening mechanism. The beating mechanism includes a central rotating shaft and multiple beating rods arranged at equal intervals. Each beating rod includes an arc-shaped segment and a straight rod segment connected to both ends of the arc-shaped segment. The straight rod segments at both ends of the beating rod are installed at both ends of the central rotating shaft. According to the beating sequence, the distance from the arc-shaped segment of each beating rod to the central rotating shaft increases progressively.

[0007] Based on the above, a telescopic mechanism is provided between the central rotating shaft and each of the straight rod segments to adjust the extension distance of each of the striking rods.

[0008] Based on the above, the telescopic mechanism includes a sleeve disposed on the central rotating shaft and a row of threaded holes opened on the straight rod section, the straight rod section being inserted into the sleeve, and a locking bolt being disposed on the sleeve corresponding to the threaded holes.

[0009] Based on the above, two silicone sleeves are movably fitted on each of the arc segments, and the two silicone sleeves are symmetrically arranged with respect to the central cross section of the arc segment; on the outer convex side of the arc segment, the outer end of the silicone sleeve protrudes more than the inner end.

[0010] Based on the above, the striking rod is provided with a total of three rods.

[0011] This invention has substantial features and advancements compared to the prior art. Specifically, by progressively increasing the distance from the arc-shaped segment of each of the striking rods to the central pivot, the invention gradually increases the contact width with the fabric during striking, allowing the fabric to gradually unfold and thus making it easier to untwist. It also achieves a good unfolding effect for fabrics with high twist. Compared to the prior art, the structure is simpler and more convenient to use.

[0012] Furthermore, the telescopic mechanism facilitates adjustment of the extension distance of each of the striking rods, thereby adjusting the contact width with the fabric; the movement of the two silicone sleeves on the arc segment can slightly adjust the outer curvature, improving adaptability.

[0019] The technical solution of this utility model will be further described in detail below through specific embodiments. Example 1

[0020] like Figure 2-4 As shown, a textile fabric leveling device includes a de-twisting mechanism 2, a spreading mechanism 3, and a beating mechanism 7 connected between the de-twisting mechanism 2 and the spreading mechanism 3. This part belongs to the common structure of de-twisting spreading machines in the prior art. This patent mainly improves the beating mechanism 7.

[0021] The beating mechanism 7 includes a central rotating shaft 8 and three equally spaced beating rods. Each beating rod includes an arc-shaped segment 9 and straight rod segments 10 connected to both ends of the arc-shaped segment 9. The straight rod segments 10 at both ends of the beating rod are installed at both ends of the central rotating shaft 8. A telescopic mechanism is provided between the central rotating shaft 8 and each straight rod segment 10. The telescopic mechanism specifically includes a sleeve 11 provided on the central rotating shaft 8 and a row of threaded holes 12 opened on the straight rod segment 10. The straight rod segment 10 is inserted into the sleeve 11. A locking bolt 13 is provided on the sleeve 11 corresponding to the threaded holes 12 to adjust the extension distance of each beating rod. When the fabric twist is high, the distance from the arc-shaped segment 9 of each beating rod to the central rotating shaft can be adjusted to increase in sequence according to the beating order.

[0022] Working principle:

[0023] Adjust the extension distance of each of the beating rods according to the fabric condition. The fabric passes in front of it, and the central rotating shaft 8 carries the beating rods to intermittently beat the fabric. Since the distance from the arc segment 9 of each beating rod to the central rotating shaft 8 is set to increase progressively, the contact width with the fabric can be gradually increased when beating the fabric, so that the fabric can be gradually unfolded, making it easier to untwist. It can also achieve a good unfolding effect for fabrics with high twist. Example 2

[0024] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that two silicone sleeves 14 are movably fitted onto each of the arc-shaped segments 9 (the silicone sleeves 14 should be tightly fitted onto the arc-shaped segment 9 and remain stationary in their natural state). The two silicone sleeves 14 are symmetrically arranged relative to the central cross-section of the arc-shaped segment 9; on the outer convex side of the arc-shaped segment 9, the outer end of the silicone sleeve 14 protrudes more than the inner end. In use, by moving the two silicone sleeves 14 on the arc-shaped segment 9, the outer curvature can be slightly adjusted, further improving adaptability.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
