AI Technical Summary
[0002]一次性口罩的口罩布通过多根起皱辊起皱后再通过折叠板定型,最后压片形成可裁切的折叠布,在通过折叠板的走布通道之前,口罩布需要逐步收拢,形成皱褶,并通过口罩布进入走布通道之前调整位置,使口罩布的两端与走布通道的两侧对齐,目前,起皱辊多为固定式的,需要的辊道较多,以平缓的梯次收拢口罩布,数量较少很容易形成多余皱褶,多辊道的方式不仅设备成本高,且占用空间大
[0006]本方案通过磁力控制套管在芯辊上的位置,从而调整口罩布的收幅,使口罩布宽幅、侧边位置可调,在口罩布进入由折叠板组成的走布通道之前,沿线设置多个这种导布装置,进入走布通道之前,各起皱盘直径逐步增大,倾角逐步减小,宽幅逐步收缩,使布逐步收拢,相较于固定式的起皱辊而言,这种导布装置单次收拢的幅度可以更大,在出现不理想牵引状态时,可以通过调整套管的轴向位置和起皱盘的位置来避免口罩布不必要的皱褶的产生。

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mask processing equipment, and in particular to a cloth guiding device for folding and gathering mask fabric. Background Technology
[0002] The fabric of disposable masks is pleated by multiple pleating rollers and then shaped by a folding plate. Finally, it is pressed into a foldable fabric that can be cut. Before passing through the fabric path of the folding plate, the mask fabric needs to be gradually gathered to form pleats. The position of the mask fabric is adjusted before entering the fabric path so that the two ends of the mask fabric are aligned with the sides of the fabric path. At present, most of the pleating rollers are fixed, requiring a large number of rollers to gently gather the mask fabric in stages. If the number is small, it is easy to form excess pleats. The multi-roller method is not only expensive in terms of equipment cost, but also occupies a lot of space. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention proposes a fabric guiding device capable of actively adjusting the traction state of the mask fabric.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a guide device for folding and gathering mask fabric, characterized in that it includes a core roller and two sleeves sleeved at both ends of the core roller, the sleeves being rotatably connected to the core roller, the outer end of the sleeve having a limiting ring, and a magnetic adjustment mechanism being provided between the sleeve and the end of the core roller on the same side, the magnetic adjustment mechanism including a magnetic coil disposed at the end of the core roller and a permanent magnet block fixed outside the limiting ring.
[0005] Furthermore, a pleating disc is fixedly provided on the sleeve at an acute angle to the axis of the core roller.
[0006] This solution uses magnetic force to control the position of the sleeve on the core roller, thereby adjusting the width of the mask fabric. This makes the width and side position of the mask fabric adjustable. Before the mask fabric enters the fabric feeding channel composed of folding plates, multiple such guiding devices are set along the line. Before entering the fabric feeding channel, the diameter of each pleating disc gradually increases, the inclination angle gradually decreases, and the width gradually shrinks, causing the fabric to gradually gather. Compared with fixed pleating rollers, this guiding device can gather a larger range at a time. In case of unsatisfactory traction, the axial position of the sleeve and the position of the pleating discs can be adjusted to avoid unnecessary wrinkles in the mask fabric.

[0009] Legend: 1. Core roller; 2. Sleeve; 3. Limiting ring; 4. Magnetic coil; 5. Permanent magnet; 6. Pleating disc. Detailed Implementation
[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0011] like Figure 1 and Figure 2 As shown, it includes a core roller 1 and two sleeves 2 sleeved at both ends of the core roller 1. The sleeves 2 are rotatably connected to the core roller 1. The outer end of the sleeve 2 has a limiting ring 3. A magnetic adjustment mechanism is provided between the sleeve 2 and the end of the core roller 1 on the same side. The magnetic adjustment mechanism includes a magnetic coil 4 provided at the end of the core roller 1 and a permanent magnet block 5 fixed outside the limiting ring 3. A pleating disc 6 is fixedly provided on the sleeve 2 at an acute angle to the axis of the core roller 1.
[0012] This solution uses magnetic force to control the position of the sleeve 2 on the core roller 1, thereby adjusting the width of the mask fabric. This makes the width and side position of the mask fabric adjustable. Before the mask fabric enters the fabric feeding channel composed of folding plates, multiple such guiding devices are set along the line. Before entering the fabric feeding channel, the diameter of each pleating disc gradually increases, the inclination angle gradually decreases, and the width gradually shrinks, so that the fabric is gradually gathered. Compared with fixed pleating rollers, this guiding device can gather a larger range at a time. When an unsatisfactory traction state occurs, the axial position of the sleeve 2 and the position of the pleating discs can be adjusted to avoid unnecessary wrinkles in the mask fabric.
[0013] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
