Description

Technical Field

[0001] The utility model relates to the field of textiles, and more specifically, it relates to a cutting device for a chenille yarn spinning machine. Background Art

[0002] Chenille yarn is a special yarn, which is famous for its unique fluffy texture and soft handfeel. In the chenille yarn production industry, most chenille spinning machines are low-speed machines, with a rotational speed between 4000 and 6000, and the working efficiency is relatively low. In order to improve the working efficiency of chenille spinning machines, in addition to increasing the number of yarn spindles, it is also necessary to increase the rotational speed of the spinning machines. The traditional cutting device of chenille spinning machines cannot meet the processing requirements of high-speed spinning machines, which will seriously affect their working efficiency. To solve this problem, the cutting device for a high-speed chenille spinning machine disclosed in the Chinese patent with the publication number CN214992118U is provided.

[0003] After long-term use, the cutting edge of the blade will decline in cutting effect due to wear, and it will also affect the cutting effect due to adhesion and adsorption of impurities such as dust and fiber residues. Therefore, in order to ensure stable cutting effect, it is necessary to regularly remove the blade for cleaning and maintenance. In this solution, the blade is fixed on the fixed seat through clip pieces, multiple fixing holes, multiple bolt holes and multiple bolts. To disassemble and assemble the blade, it is necessary to first disassemble multiple bolts, which is rather troublesome and time-consuming. During the process of disassembling and assembling the blade, the spinning machine needs to stop, which also indirectly reduces the production efficiency.

[0004] Based on the above, the purpose of the present utility model is to provide a cutting device for a chenille yarn spinning machine to solve the above problems. Content of the Utility Model

[0025] Furthermore, the fixing seat 1 is provided with an abutment portion 9 for limiting the blade 2. The abutment portion can be the inner wall of the mounting groove. The limiting portion 6 and the limiting groove 7 are both inclined toward the abutment portion 9 and can also be a hook-shaped structure or a circular structure.

[0026] Furthermore, a baffle 10 is slidably connected in the insertion groove 8, and magnetic attracting parts that can be attracted to each other are fixedly connected on the baffle 10 and the inner wall of the insertion groove 8.

[0027] Furthermore, a spring 11 is installed in the slide groove 5 , and two ends of the spring 11 abut against the inner wall of the slide groove 5 and the mounting block 4 respectively.

[0028] Furthermore, clamping plates 12 are slidably connected to both sides of the installation groove 3, and a driving mechanism for driving the clamping plates 12 on both sides to gather inwards is provided on the fixing seat 1.

[0029] Furthermore, the driving mechanism includes a plurality of connecting rods 13 respectively arranged on both sides of the mounting block, one end of the connecting rod 13 is fixedly connected to the mounting block 4, the other end of the connecting rod 13 is fixedly connected to a pressure plate 14, a pressure block 15 is fixedly connected to the pressure plate 14, and the sides of the pressure block 15 and the clamping plate 12 that are in contact with each other are both inclined.

[0030] Furthermore, chamfers 16 are formed on the clamping plates 12 on both sides.

[0031] Working principle: When the blade 2 needs to be installed, insert the blade 2 into the installation slot 3. The chamfer 16 can make it easier for the blade 2 to be inserted into and pass through the two side clamps 12 until the limit portion 6 is inserted into the limit slot 7. Then rotate the bolt 17 to move the bolt into the slide slot 5.

Under the action of the spring 11, the mounting block 4 moves in the reverse direction until the limiting portion 6 moves to the other side of the limiting groove 7. At this time, the clamping plates 12 on both sides also lose the restriction of the pressing block 15 and loosen the blade 2. At this time, the blade 2 can be pulled out, making the disassembly and assembly of the blade 2 more convenient.

[0033] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments.
