Description

Technical Field

[0001] The utility model relates to the technical field of textile processing, in particular to a thread-breaking prevention yarn seat for a computerized flat knitting machine. Background Art

[0002] A textile yarn bobbin is a device used for spinning, winding and storing yarn, and needs to cooperate with the textile machine to release the yarn when the textile machine is working. Therefore, it is widely used in textile production and processing sites.

[0003] When the computerized flat knitting machine is working, a bobbin needs to be placed on the top of the machine body for thread feeding, and the yarn wound on the bobbin is pulled into the computerized flat knitting machine through the yarn mouth for knitting. In actual operation, for convenience, the operator usually directly places the bobbin with the yarn wound on the frame of the computerized flat knitting machine.

[0004] The yarn used is usually a lighter filament such as polyester. The filament is not only light but also elastic. The yarn wound on the bobbin presents an inverted cone shape near the bottom of the bobbin. When the bobbin is placed on the top of the machine body, the yarn mouth brings the filament into the computer flat knitting machine for use until it stops. Due to inertia, a section of the filament on the bobbin will fall on the top of the computer flat knitting machine body, and at this time it will be located at the bottom of the inverted cone of the yarn on the bobbin. When the filament is brought into the computer flat knitting machine by the yarn mouth after use again, this section of the filament will be stuck at the bottom of the bobbin and break at the moment of use. The probability of this breakage reaches more than 80% of the total number of breakages. The breakage will make the woven fabric become waste pieces, affecting the quality of the fabric, and thus reducing the efficiency of weaving. Reducing the number of filament breakages in order to reduce the generation of waste pieces and improve production efficiency is an important issue that needs to be solved urgently.

[0010] Option 4 is a preferred option of Option 3. A positioning block is connected to the base, the positioning block is located in the middle of the base, and the elastic member is sleeved on the positioning block. By setting the positioning block, it is convenient to sleeve the elastic member on the positioning block, so that the elastic member can remain stable and avoid sliding.

[0011] Option 5 is a preferred option of Option 4, in which a suction cup is connected to the bottom of the base; by providing the suction cup, the base can be more stable when placed on the top of the computer flat knitting machine body.

[0012] Option six is ​​a preferred option of option two. The thickness of the elastic member is 2 cm, and the diameter of the elastic member is 20 cm. The size of the elastic member is set to match the size of the base to better support the yarn tube and receive the temporarily fallen yarn.

[0013] Option seven, which is a preferred option of Option five, is that the distance between the top of the elastic member and the top of the base accounts for 1 / 3 of the total height of the base; when the yarn bobbin is placed in the base, the elastic member can rest against the portion with the maximum radius of the yarn wound around the yarn bobbin, thereby preventing the elastic member from being squeezed and unable to rest against the yarn of the yarn bobbin when the yarn bobbin is placed on the elastic member due to the low height of the elastic member.
