Description

Technical Field

[0001] This utility model relates to the field of fabric processing, and more specifically, it relates to a guide device for correcting the deviation of a napping machine. Background Technology

[0002] In the fabric napping process, roller sets are usually used as the fabric conveying system. However, during the process of conveying the fabric by the roller sets, the fabric often deviates on the roller sets. At this time, a correction device is needed to correct the fabric deviation. One of the existing correction methods is to use a sensor to detect the fabric deviation, and then use a correction roller that can move horizontally to adjust the position of the fabric. Then, an auxiliary roller picks up the fabric, causing the fabric to detach from the correction roller. The correction roller resets, and then the auxiliary roller resets, so that the fabric re-contacts the correction roller.

[0003] However, when the straightening roller lifts up the fabric, the fabric may still shift, causing the operating frequency of the straightening roller and auxiliary roller to increase, which affects the efficiency of the straightening guide device of the napping machine. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a guide device for correcting the deviation of a napping machine.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a guide device for correcting the deviation of a brushing machine, including an auxiliary roller, on which two limiting plates are slidably connected, and a limiting module for limiting the sliding of the limiting plate is provided on the side of the limiting plate opposite to the other limiting plate.

[0006] The present invention is further configured such that: a plurality of guide grooves are provided on the side wall of the auxiliary roller, and a plurality of sliders are integrally formed on the inner side of the limiting plate, the sliders being slidably connected in the guide grooves.

[0007] The present invention is further configured such that: the limiting module is composed of a plurality of friction blocks, the friction blocks correspond to the slider, the friction blocks are fixedly connected to the side wall of the slider, and the friction blocks are made of elastic material.

[0008] The present invention is further configured such that the sidewall of the guide groove and the sidewall of the auxiliary roller have a circular arc transition.

[0009] The present invention is further configured such that the diameter of the outer edge of the cross section of the limiting plate gradually increases along the direction away from the other limiting plate.

[0010] The present invention is further configured such that the side of the limiting plate near the other limiting plate forms a plane perpendicular to the axis of the auxiliary roller.

[0011] In summary, this utility model has the following beneficial effects: when the straightening roller corrects the fabric to the correct position, the limiting plate prevents the fabric from shifting when it comes into contact with the auxiliary roller, reduces the operating frequency of the straightening roller and the auxiliary roller, thereby improving the efficiency of the straightening guide device of the napping machine, and avoids unnecessary damage to the fabric caused by the edges between the sidewall of the guide groove and the sidewall of the auxiliary roller, thus ensuring the quality of the fabric.

[0015] In the diagram: 1. Auxiliary roller; 2. Limiting plate; 3. Guide groove; 4. Slider; 5. Friction block. Detailed Implementation

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Example: A guide device for correcting the deviation of a napping machine, such as... Figure 1 , Figure 2 , Figure 3 As shown, it includes an auxiliary roller 1, on which two limiting plates 2 are slidably connected. On the side of the limiting plate 2 opposite to the other limiting plate 2, there is a limiting module for limiting the sliding of the limiting plate 2. Several guide grooves 3 are opened on the side wall of the auxiliary roller 1. Several sliders 4 are integrally formed on the inner side of the limiting plate 2. The sliders 4 are slidably connected in the guide grooves 3. The limiting module is composed of several friction blocks 5. The friction blocks 5 correspond to the sliders 4 and are fixedly connected to the side wall of the sliders 4. The friction blocks 5 are made of elastic material.

[0018] Specifically, the web guiding device of the napping machine mainly consists of a frame, a web guiding roller, and an auxiliary roller 1. The two ends of the auxiliary roller 1 are rotatably connected to connecting rods, which are rotatably connected to the frame. These connecting rods drive the auxiliary roller 1 to rotate around the web guiding roller. Three guide grooves 3 are provided on the side wall of the auxiliary roller 1. Three sliders 4 are integrally formed on the inner side of the limiting plate 2. The sliders 4 slide within the guide grooves 3, meaning the limiting plate 2 can slide on the auxiliary roller 1, aligning the position of the limiting plate 2 with the expected position of the fabric. When the web guiding roller corrects the fabric to the correct position, the limiting plate 2 prevents the fabric from shifting when in contact with the auxiliary roller 1, reducing the operating frequency of the web guiding roller and the auxiliary roller 1, thereby improving the efficiency of the web guiding device of the napping machine. The friction block 5 is made of rubber, and its elastic deformation applies pressure to the side wall of the guide groove 3, increasing friction and thus limiting the sliding of the limiting plate 2. The friction block 5 is located on the side of the limiting plate 2 away from the other limiting plate 2, preventing contact between the friction block 5 and the fabric.

[0019] like Figure 2 As shown, the sidewall of the guide groove 3 and the sidewall of the auxiliary roller 1 are connected by a rounded transition. Specifically, the sidewall of the guide groove 3 and the sidewall of the auxiliary roller 1 are rounded to avoid unnecessary damage to the fabric from the sharp edges between them, thus ensuring the quality of the fabric.

[0020] like Figure 2 , Figure 3 As shown, the diameter of the outer edge of the limiting plate 2 gradually increases along the direction away from the other limiting plate 2. The side of the limiting plate 2 closest to the other limiting plate 2 forms a plane perpendicular to the axis of the auxiliary roller 1. Specifically, the limiting plate 2 is a hollow frustum shape. When the fabric still has a slight deviation after being corrected by the correction roller, the inclined sidewall of the limiting plate 2 can further guide the fabric to correct its deviation, causing the fabric to tend to be between the two limiting plates 2. The side of the limiting plate 2 closest to the other limiting plate 2 forms a plane perpendicular to the axis of the auxiliary roller 1, which avoids the edge of the fabric from touching the inclined surface of the limiting plate 2, further ensuring the correct position of the fabric.

[0021] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
