Description

Technical Field

[0001] This utility model relates to the field of yarn feeding technology for knitting machines, and in particular to a novel yarn feeding device for knitting machines. Background Technology

[0002] The knitting mechanism is the heart of a circular knitting machine, and the yarn feeder is a part of it. The main body of the yarn feeder is usually supported and fixed on the cutting plate by the yarn feeder arm.

[0003] During the installation, fabric feeding, and debugging of the knitting machine, the position of the yarn feed ring needs to be adjusted left and right. The center position of the adjusted yarn feed ring must be consistent to ensure the correct yarn feeding position. The existing yarn feed ring body is usually supported and fixed on the cutting plate by the yarn feed support arm. The yarn feed ring is pressed into the yarn feed support arm by bolts and washers. In order to ensure that the bolts drive the washers to provide sufficient clamping force to the yarn feed ring, the bolts and the yarn feed ring are very close. During subsequent maintenance and adjustment of the yarn feed ring, the bolts will hinder the movement of the yarn feed ring.

[0004] In the existing technology, the support frame and the main structure of the yarn feeding ring are firmly fixed with bolts or other fixing methods, which makes it inconvenient to separate them during subsequent inspection and maintenance, resulting in inconvenience in use and making it impossible to achieve portable disassembly. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of knitting machine feed ring, which solves the problem that the support frame and the main structure of the feed ring are fixed firmly with bolts or other fixing methods, making it inconvenient to separate them during subsequent inspection and maintenance, resulting in inconvenience in use and making it impossible to achieve portable disassembly operation.

[0006] To achieve the above objectives, a novel knitting machine yarn feeder is provided, comprising: a yarn feeder body, four support frames equidistantly supported at the bottom end of the yarn feeder body, a fixing block fixedly connected to the top end of each support frame, the fixing block and the yarn feeder body engaging in abutment; a plurality of yarn feed nozzles equidistantly fitted to the top end of the yarn feeder body, a bolt rod passing through the yarn feed nozzles and the yarn feeder body; and slots provided between the yarn feeder body and the support frames, with L-shaped locking blocks inserted into the slots.

[0007] The fixed block has a groove inside, and a support spring is fixedly connected to the bottom of the groove.

[0008] A slider is fixedly connected to the top of the support spring, and a connecting rod is fixedly connected to the inner side of the slider. The connecting rod is sleeved inside the support spring.

[0009] A connecting protrusion is fixedly connected to the top of the slider, and a control rod is fixedly connected to the outside of the connecting protrusion.

[0010] An opening is provided between the control rod and the fixing block.

[0011] The connecting rod and the L-shaped locking block are fixedly connected.

[0012] A mounting plate is fixedly connected to the bottom end of the support frame.

[0013] A bolt is fixedly connected to the top end of the bolt rod, and a nut is threadedly connected to the bottom end of the bolt rod.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. By aligning the slots between the support frame and the main body of the yarn feeding ring, the L-shaped locking block can engage with the slots, achieving an integrated structure of the main body of the yarn feeding ring and the support frame. Simultaneously, the support spring provides elastic support, lifting the slider upwards. After lifting, the control rod moves upwards, and then the bolt rod passes through the top of the main body of the yarn feeding ring and the top of the yarn feeding nozzle, and is tightened with a nut to achieve the installation function.

[0016] 2. Press down the control lever. At this time, the support spring will press down elastically, the connecting rod will move downward, and the L-shaped locking block at the bottom will slide downward. Then the L-shaped locking block will disengage from the slot, thus achieving the separation function. This facilitates the disassembly of the yarn feeding ring body and the support frame, and achieves the disassembly and removal function. Attached Figure Description

[0023] Reference Figure 1-4This utility model relates to a novel yarn feeder for a knitting machine, comprising a yarn feeder body 1. Four support frames 3 are equidistantly supported at the bottom end of the yarn feeder body 1. A fixing block 5 is fixedly connected to the top of each support frame 3. The yarn feeder body 1 is supported on the upper surface of the support frame 3, and then the fixing blocks 5 abut against the outer side of the yarn feeder body 1, forming abutting engagement. A plurality of yarn feed nozzles 2 are equidistantly attached to the top of the yarn feeder body 1. A bolt rod 15 passes through the yarn feed nozzles 2 and the top of the yarn feeder body 1, and is connected via a screw... The mother 14 is threaded to fasten the yarn feeder body 1 and the support frame 3. The two are provided with slots 10. The slots 10 between the support frame 3 and the yarn feeder body 1 are aligned. The L-shaped block 11 can be engaged with the slot 10. The L-shaped block 11 is inserted into the slot 10.
