Description
Technical Field
[0001] This utility model relates to the field of sewing machine equipment, specifically to an edge scraper. Background Technology
[0002] A dial linking machine, also known as a circular sewing machine or circular stitching machine, is a machine that uses sewing thread to sew the edges of sweaters. It can efficiently and quickly complete the sewing of sweater pieces, significantly improving efficiency compared to hand sewing. However, current technology is limited in function, requiring manual loading of material stitch by stitch onto the needles, greatly reducing production efficiency and increasing labor costs. To address these shortcomings, application number: 202121782588 .2 A high-stability sewing machine is proposed, which is equipped with an edge scraper, including an edge scraper base, a movable sleeve rod, a connecting rod, a bearing, an edge scraper block, and a handle. In the above structure, the edge scraper block is set on a plurality of sewing needles. By holding the handle and moving it back and forth, the upper edge scraper block scrapes the material into the needle plate. However, the above-mentioned single edge scraper block can only ensure that the material placed on the side above the sewing needle is smoothly scraped into the needle plate. Some of the material is still placed below the sewing needle. The edge scraper block on the upper side cannot take care of the material below the sewing needle. The material on the lower side is prone to jamming when scraping into the needle plate, resulting in reduced production efficiency. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology.
[0004] A scraper is provided, which has scraping blocks coaxially positioned above and below the needle plate. It simultaneously scrapes the material above and below the needle plate, avoiding jamming and ensuring production efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an edge scraper, comprising an edge scraper base connected to a fixed plate, the edge scraper base being rotatably provided with a rotating rod, the rotating rod being provided with a connecting rod, and the connecting rod being provided with an mounting rod for mounting edge scraping blocks and a handle for hand gripping at one end relative to the rotating rod, characterized in that: the mounting rod is mirror-mounted with adjustable spacing limit seats, and an edge scraping assembly capable of displacement between the limit seats is provided between the limit seats, the edge scraping assembly comprising a sleeve rod, the sleeve rod being movably sleeved on the mounting rod and placed between the two limit seats, the sleeve rod being provided with positioning seats at both ends, and the sleeve rod being rotatably provided with two edge scraping blocks between the positioning seats, the two edge scraping blocks forming an edge scraping gap capable of allowing the disc needle to pass through.
[0006] The present invention, which has the above-mentioned features, has the following characteristics: the scraping component can be displaced between the limiting seats. When the scraping block abuts against the disc needle, due to the force, the disc needle pushes the scraping block to move until the disc needle enters the scraping gap. It has adaptive height adjustment and the scraping block can rotate, reducing damage to the disc needle. The two scraping blocks are respectively placed above and below the disc needle, taking into account the material above and below the disc needle and scraping it into the needle disc simultaneously, avoiding jamming and ensuring production efficiency.
[0007] A further feature of this invention is that the positioning seat is threadedly connected to the sleeve rod.
[0008] The present invention, which has the above-mentioned features, has a detachable connection, making it convenient to assemble and disassemble.
[0009] A further feature of this invention is that the scraping block includes a bearing and an annular outer wheel body, the outer wheel body being connected to the outer ring of the bearing, and the positioning seat abutting against the inner ring of the bearing.
[0010] The present invention, which has the above-mentioned features, avoids the positioning seat from affecting the rotation of the scraping block.
[0011] A further feature of this invention is that the connecting rod is provided with a groove, the width of which is smaller than the diameter of the rotating rod, and a first positioning screw is threadedly fitted at the end of the rotating rod. The first positioning screw passes through the groove and is threadedly fitted to the end of the rotating rod, and the rotating rod abuts against the connecting rod.
[0012] The present invention having the above features includes: the distance between the rotating rod and the mounting rod is adjustable.
[0013] A further feature of this invention is that the connecting rod is provided with a first mounting groove, the handle abuts against the connecting rod, and the end of the handle is provided with a second positioning screw, which passes through the first mounting groove and is threadedly connected to the end of the handle.
[0014] A further feature of this invention is that: the end of the mounting rod abuts against the connecting rod; the connecting rod has a bracket on one side opposite the mounting rod; the bracket has a second mounting groove; the end of the mounting rod has a third positioning screw; the third positioning screw passes through the first mounting groove and the second mounting groove and is threadedly connected to the end of the mounting rod; the bracket has a rod body; the rod body has a rolled edge unfolding head; the rolled edge unfolding head has an opening; the opening has a bevel; and the bevel has several grooves.
[0015] The present invention, which has the above features, allows for the following: when the width of the fabric hem is short, the end of the fabric hem is placed in the groove, and the other parts of the fabric abut against the opening of the opening. Pulling the fabric will unfold the hem. When the length of the fabric hem is long, the end of the fabric hem is placed at the upper opening of the opening, and the other parts of the fabric abut against the lower opening of the opening. Pulling the fabric will unfold the hem.
[0016] The beneficial effects of this utility model are: it is coaxially provided with scraping blocks that are placed both above and below the needle, so as to take care of the material above and below the needle and scrape it into the needle plate at the same time, avoiding jamming and ensuring production efficiency.
[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description
