Description

A new type of precision fork device

technical field

The invention relates to the technical field of machinery, in particular to a novel precision shifting fork device.

Background technique

Generally speaking, the control mechanism of the winding device stroke (yarn winding track stroke) of the yarn doubling machine currently on the market is divided into: mechanical grooved drum, precision pick and precision ordinary fork structure, new precision fork The shifting fork of the device is specially customized. The mechanical structure of the winding part of the grooved drum type and the paddle type doubling machine is complex and the volume is large. Generally, the motor used has high power, high energy consumption and low efficiency. In addition, the shifting fork is not The common shifting fork used in the spinning frame is heavy in weight, poor in rigidity of the fork legs and insufficient in wear resistance. Due to the large friction between the cotton yarn and the fork feet), there are many problems such as polluting the production environment.

SUMMARY OF THE INVENTION

In order to solve the above problems, the present invention provides a novel precision shifting fork device.

The technical solution adopted by the present invention to solve the technical problem is: a new type of precision shifting fork device, comprising a shifting fork device, characterized in that: the shifting fork device comprises a rotating shaft, a shifting fork fixing rod and a shifting fork guide rod; The fork fixing rod is symmetrically arranged on the outer surface of the rotating shaft and extends laterally, and the width between them gradually decreases to form a "Y"-shaped structure. The end of the fork fixing rod is provided with a fork guide rod. The diameter of the guide rod is slightly smaller than the diameter of the fork fixing rod, and they keep a certain wide distance from each other.

Further, the side surface of the rotating shaft is arc-shaped or rectangular.

Further, the side surface of the fork fixing rod is arc-shaped or rectangular.

Further, the fork guide rod is metal or ceramic with special surface treatment.

Further, the fork fixing rod is made of carbon fiber material.

The beneficial effects of the present invention are as follows: in the present application, the yarn is guided by the fork device, which can effectively reduce the load of the motor and improve the efficiency of the motor. The overall weight is reduced, and the fork guide rod is made of metal or ceramic material with special surface treatment, which prevents the cotton yarn and the fork guide rod from rubbing against each other to produce lint contamination, which affects the air and yarn quality, and further improves the winding. Accuracy, make the yarn winding better, reduce the breakage rate of other processes such as unwinding, save production costs and improve production efficiency.

Detailed ways

In order to make the technical solutions of the present invention clearer, the present invention will be further described below with reference to the specific embodiments of the accompanying drawings.

As shown in Figures 1-2, a novel precision fork device according to an embodiment of the present invention includes a fork device 1, which is characterized in that: the fork device 1 includes a rotating shaft 11, a fork fixing rod 12 and a fork The guide rod 121, the fork fixing rod 12 is symmetrically arranged on the outer surface of the rotating shaft 11, and extends laterally, and the width between them gradually decreases, forming a "Y"-shaped structure, and the end of the fork fixing rod 12 is provided with The fork guide rod 121, the diameter of the fork guide rod 121 is slightly smaller than the diameter of the fork fixing rod 12, and a certain wide distance is maintained between them.

Further, the side surface of the rotating shaft 11 is arc-shaped or rectangular.

Further, the side surface of the fork fixing rod 12 is arc-shaped or rectangular.

Further, the fork guide rod 121 is metal or ceramic with special surface treatment.

Further, the fork fixing rod 12 is made of carbon fiber material.

As shown in Figure 1-2, when the application needs to be used to guide the yarn, first install the application on the motor shaft head of the fork equipment, and then put the yarn through the guide port 2 and put the yarn into the fork. Between the fork guide rods 121, after the preparation is completed, the motor switch of the fork device is turned on. The motor starts and runs to drive the fork device 1 to rotate left and right, and further drives the yarn to reciprocate, so that the yarn is automatically wound on the bobbin. During the reciprocating motion, in the process of guiding the yarn by the fork device 1, because the fork fixing rod 12 is made of carbon fiber, it has strong rigidity and reduces its overall weight, while the fork guide rod 121 has a special surface as a whole. The treated metal or ceramic material has a certain wear resistance on the surface, preventing the yarn from rubbing against each other and affecting the quality of the yarn, achieving the beneficial effects of ensuring product quality and improving operating efficiency.

The above embodiments can be combined with each other under the condition that they are not opposite to each other for further implementation.

The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. The equivalent replacement or modification of the solution and its inventive concept shall be included within the protection scope of the present invention.
