Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology and relates to an automatic alarm device for stopping the cutting edge of the machine. Background Technology

[0002] Trimming structures are mainly used in the garment processing field to cut woven fabrics. As the trimming capacity of processing machines increases and the types of trimmed fabrics become more diversified, abnormalities, especially breakage, are becoming more and more common in trimmed fabrics.

[0003] Because of abnormalities such as poor selvage twisting, broken edges, and fraying in the weaving section, the ear fabric often breaks. If not detected in time, it will get tangled in the guide roller, causing damage to the fabric surface and yarn shifting. This is especially true for fabrics with abnormal width shrinkage, which are more likely to have issues such as the selvage not being cut on both sides, the ear fabric breaking on both sides, and the feathering not being cut. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic alarm device for the interruption of ear material in the edge cutting area of ​​a processing machine. By monitoring the ear material structure, it can promptly detect ear material abnormalities, prompt personnel to handle them, and promptly detect ear material breakage problems, thereby improving the edge cutting effect of fabric weaving.

[0005] To address the aforementioned problems, the present invention provides an automatic alarm device for stopping the cutting edge material in the edge-cutting area of ​​a processing machine, comprising:

[0006] Guide braces, at least two parallel ones;

[0007] Fiberglass cloth is wound around the outer periphery of the guide roller, which rotates to convey the fiberglass cloth; an edge trimming structure is provided on the side of the fiberglass cloth to cut off the fiberglass cloth ear material as the fiberglass cloth is conveyed.

[0008] Ear material guide rollers transport the fiberglass cloth ear material to an external ear material box;

[0009] A tachometer is used to monitor the rotational speed of the ear material guide rollers;

[0010] An alarm is electrically connected to the speed measuring instrument; when the speed measuring instrument detects an abnormal rotation speed of the fiberglass cloth guide roller, it transmits a signal to the alarm. This allows for timely detection of abnormalities in the fiberglass cloth guide roller and alerts operators, reducing material loss during weaving.

[0011] According to this utility model, the trimming structure further includes a cutting blade and a blade pad used in conjunction with it, forming a cutting angle between the two to trim the fiberglass cloth ear material.

[0012] According to this utility model, the trimming structure is further provided in two parts, which are respectively disposed on both sides of the glass fiber cloth.

[0013] According to this utility model, the virtual connecting line of the cutters on both sides is perpendicular to the glass fiber cloth conveying direction.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model uses a speed measuring instrument and an alarm connected to it to detect problems in a timely manner and reduce material loss caused by abnormal trimming;

[0016] 2. Saves workers' working time, eliminating the need for constant monitoring of the cutting edges and reducing labor intensity;

[0017] 3. Save company costs and improve product quality. Attached Figure Description

[0021] To make this utility model more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings:

[0022] like Figure 1 and Figure 2 As shown in the embodiment of this application, the technical solution provided is an automatic alarm device for interruption of fiberglass cloth cutting area in a processing machine. This device monitors the rotational speed of the cutting guide rollers and issues an alarm when the rollers' speed becomes abnormal, promptly alerting the operator to take action. The automatic alarm device includes parallel guide rollers 1, which guide fiberglass cloth 2 into and out of the machine frame. A cutting structure is provided on the side of the fiberglass cloth 2, cutting off fiberglass cloth cutting material 3 as the cloth 2 is conveyed, ensuring the cut fiberglass cloth 2 meets customer requirements. Preferably, the cutting structure includes a cutter 5 and a cutting pad 6 used in conjunction with it, forming a cutting angle to cut the fiberglass cloth cutting material 3. One end of the fiberglass cloth cutting material 3 is guided to the cutting box via the cutting guide roller 4. There are two cutting blades 5, one on each side of the fiberglass cloth 2 in the width direction, which simultaneously cut the fiberglass cloth ear pieces 3 on both sides, improving cutting efficiency; correspondingly, there are also two ear piece guide rollers 4, which correspond to the positions of the fiberglass cloth ear pieces 3 on the corresponding sides. It should be noted that "both sides" here refers to... Figure 1The left and right sides of the fiberglass cloth 2 in the indicated direction.

[0023] Specifically, a speed measuring instrument 7 is also installed to monitor the rotational speed of the guide roller 4, and the speed measuring instrument 7 is electrically connected to an alarm 8. When the speed measuring instrument 7 detects an abnormal rotational speed of the guide roller 4, it transmits a signal to the alarm 8, which then alarms to remind the operator to handle the situation in a timely manner and reduce processing losses.

[0024] The working principle of this utility model is as follows: Fiberglass cloth 2 is conveyed into the trimming area composed of cutter 5 and cutter pad 6 via guide roller 1. The cutter 5 and cutter pad 6 cut the fiberglass cloth 2 at the required angle, trimming it to the width specified by the customer. The cut fiberglass cloth earpiece 3 enters the earpiece box via earpiece guide roller 4. A speed meter 7 continuously monitors the rotation speed of the earpiece guide roller 4. When the trimming equipment is in normal production, the fiberglass cloth earpiece 3 continuously drives the earpiece guide roller 4, which maintains a constant rotation speed. When an abnormality occurs during trimming, the fiberglass cloth earpiece 3 breaks off, causing the earpiece guide roller 4 to decrease in speed until it stops. The speed meter 7 detects the abnormal speed, and the alarm 8 immediately alerts the operator to handle the abnormality.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model in any form or substance. It should be noted that those skilled in the art can make several improvements and additions without departing from this utility model, and these improvements and additions should also be considered within the protection scope of this utility model. Any modifications, alterations, and equivalent changes made by those skilled in the art based on the above-disclosed technical content without departing from the spirit and scope of this utility model are equivalent embodiments of this utility model. Furthermore, any modifications, alterations, and evolutions made to the above embodiments based on the essential technology of this utility model still fall within the scope of the technical solution of this utility model.
