Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to a cotton sliver anti-pull feeding device. Background Technology

[0002] The following problems exist during the feeding process of roving frames: Due to the difference in friction between the rollers, uneven force is easily caused in some areas of the sliver, resulting in the sliver being stretched and deformed, causing the sliver fibers to shrink and become thinner.

[0003] The aforementioned problems can damage the structural properties of tampons, which is detrimental to subsequent product production and use. Currently, the problem is often mitigated by reducing the feeding speed of the rollers into the tampons. However, the feeding speed directly affects production efficiency. In order to reduce the problem of stretching and deformation during the feeding process of tampons while providing good conveying efficiency, we propose a tampon anti-stretch feeding device.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0028] Tampon anti-pull feeding device, such as Figure 1 and Figure 2 The structure shown specifically includes:

[0029] The feeding and conveying unit includes two symmetrically arranged side fixing frames 1. Each side fixing frame 1 has a mounting hole 101. Two roller rollers 3 are rotatably mounted between the mounting holes 101 and a drive motor 7 mounted on the side fixing frame 1. It should be noted that, in order to avoid tension between the two roller rollers 3, Figure 1 For example, the feeding direction of the tampons is from right to left.

[0030] Specifically, a first transmission wheel 4 and a second transmission wheel 5 are installed on two roller rollers 3. A transmission belt 6 is fitted onto the first transmission wheel 4 and the second transmission wheel 5. In order to avoid pulling, in this embodiment, the tooth pitch of the first transmission wheel 4 and the second transmission wheel 5 is the same, and the number of teeth of the second transmission wheel 5 is less than that of the first transmission wheel 4. That is, a speed difference will be formed between the two. The roller roller 3 corresponding to the first transmission wheel 4 rotates slower than the roller roller 3 on the rear side. Therefore, during the feeding process, a long stack of cotton strips will be formed between the two roller rollers 3. This means that the cotton strips are not pulled.

[0031] In order to better support the cotton strips falling between the two rollers 3, two insertion slots 102 are provided on the side fixing frame 1, a support plate 2 is inserted between the two insertion slots 102, and a support tray 8 is installed between the two support plates 2.

[0032] Meanwhile, in order to better alleviate the problem of localized pulling of cotton strips by the roller roller 3 during the conveying process, the roller roller 3 includes a cylinder 31 with a shaft 311 at the center. The cylinder 31 is provided with a groove 312, and a rubber strip 32 is inserted into the groove 312. The rubber strip 32 has deformation capability and can improve the feeding effect.

[0033] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0034] Furthermore, if the embodiments of this utility model involve descriptions such as "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
