Description

Technical Field

[0001] This utility model relates to the field of fitted sheets, and more particularly to a semi-automatic sewing device for fitted sheets in the home textile industry. Background Technology

[0002] In existing technology, a fitted sheet is simply a fabric cover that is directly put over a mattress. It consists of elastic bands, a skirt, and the mattress itself. Its main purpose is to cover the mattress. Mattresses are very easy to get dirty and are easily damaged by people. They are also very inconvenient to clean. Fitted sheets solve this problem. In China, fitted sheets are usually used to protect the mattress. They can also be used as bed sheets. When used as bed sheets, they are easier to fix and prevent slipping than ordinary bed sheets.

[0003] In the home textile industry, the production of fitted sheets is a labor-intensive industry with complex processes, a lot of manual operation, and a large production volume. The production process involves manually sewing the mattress and skirt first. The skirt size must be calculated to match the mattress. If the calculation is wrong, it will undoubtedly cause waste. Then, elastic is attached to the skirt. During the sewing process of the elastic and skirt, it needs to be stretched and tightened by hand on both sides to prevent wrinkles. This also increases the difficulty of manual operation. The many manual operation processes also increase the factory's floor space. Utility Model Content

[0004] This application provides a semi-automatic sewing equipment for home textile fitted sheets, which solves the problems of increased manual operation difficulty, numerous manual operation procedures, and increased factory floor space in the prior art.

[0005] The technical solutions adopted in the embodiments of this application are as follows.

[0006] A semi-automatic sewing machine for fitted sheets in home textiles includes a frame, a front fabric rolling head mounted on the frame, an elastic band sewing head for sewing elastic bands onto the fitted sheet, a thread breakage stop sensor for stopping when a thread breaks, a rear fabric rolling head for pulling the fitted sheet, a fabric edge alignment sensor for detecting the opposite edges of the fabric, a thread frame mounted on the frame, and a fabric spreading plate for preventing unevenness of the fabric. The frame has a first plane and a second plane. The elastic band sewing heads are mounted on both the first and second planes. Two sets of elastic band sewing heads are arranged opposite each other on both sides of the fitted sheet. The thread breakage stop sensor is located on the first plane. The rear fabric rolling head is located on the first plane. The fabric edge alignment sensor is located on the first plane and on one side of the rear fabric rolling head. Several sets of thread frames are arranged opposite each other. Two sets of fabric spreading plates are arranged perpendicularly. Both sets of fabric spreading plates are located on the first plane.

[0007] As a further improvement to the above technical solution: a first connecting member is provided on the frame; a cloth roll is provided on the first connecting member; the cloth roll is located on one side of the rear cloth rolling head.

[0008] As a further improvement to the above technical solution: a first plate is provided on the first plane; the fabric edge sensor and the rubber band sewing machine head are both provided on the first plate; the first plate slides on the first plane via a guide rail slider.

[0009] As a further improvement to the above technical solution, an automatic start-stop device is also included.

[0010] As a further improvement to the above technical solution, a thick material overlock sewing machine head is also included.

[0011] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0012] 1. By employing two sets of opposing sewing units, simultaneous sewing on both sides of the fitted sheet is achieved, significantly improving production efficiency and greatly reducing manual labor. This innovation not only simplifies the production process but also significantly shortens the production cycle, bringing higher capacity and lower production costs to the home textile industry. Furthermore, this invention introduces a thread breakage sensor for automatic stop and a fabric edge alignment sensor for fabric edge detection, effectively ensuring sewing accuracy, reducing material waste caused by operational errors, and significantly improving product quality. For example, during the sewing of elastic bands and hemlines, real-time monitoring by the sensing device ensures the uniform distribution of elastic bands and the neatness of the hemlines, effectively avoiding quality defects such as pleats. In addition, the unique fabric spreading plate design of this invention effectively avoids unevenness of the fabric during sewing, improving the appearance quality of the fitted sheet and meeting the market's demand for high-quality home textile products. The vertical layout of the fabric spreading plate facilitates operation and reduces the need for manual adjustments. Regarding fabric supply, the invention adds a first connecting piece and fabric roll to the frame, making fabric replacement more convenient, significantly saving changeover time, and further improving production efficiency. Simultaneously, the sliding design of the first plate via a guide rail slider allows for more flexible movement of the elastic band sewing machine head and sensing device, adapting to the production requirements of different sized fitted sheets, thereby achieving automated sewing.
