Abstract
A cone yarn contact pressure control device for an automatic bobbin winder is used to solve a problem that the spring extension amount of the cone yarn contact pressure control device of the bobbin winder can not be preset. The technical scheme is that: the cone yarn contact pressure control device is positioned in a transmission case of the automatic bobbin winder; the cone yarn contact pressure control device comprises a bend connecting rod, an articulation piece, a main shaft, a cone yarn support arm and a spring, wherein one end of the spring is connected with the bend connecting rod, and the other end of the spring is fixed by a spring bolt; the spring bolt is in screw fit with a casing; after improvement, the head portion of the spring bolt is provided with an eccentric table, and one end of the spring is sleeved on the eccentric table. When the spring extension amount is needed to be adjusted, the cone yarn contact pressure control device can conveniently preset the spring extension amount by loosening a locknut of the spring bolt and rotating the spring bolt in order to meet production requirements of yarns of different kinds. The cone yarn contact pressure control device is simple in structure and delicate in conception, and solves a long-standing problem that the yarn production quality of the automatic bobbin winder fluctuates with an improved scheme which is relatively easy to achieve.
Description
Technical field
The utility model relates to a kind of automatic winder thread tension device of textile machine parts, particularly adjustable in pressure, belongs to the Weaving device technical field.
Background technology
Automatic winder is a kind of textile machine equipment of new generation, and its effect is that the cop coiled is not had knot tube yarn and in winding process, removes the yarn defect.Automatic winder is provided with a yarn contact pressure control setup, and the tube yarn presses on groove drum, and by the friction force drive tube yarn rotation of positive pressure generation between the two, the size of its friction force depends on the pressure of a yarn to groove drum.Tube yarn contact pressure control setup comprises curved rod, articulation piece, main shaft, tube yarn count arm and spring; One end of its medi-spring is connected with curved rod; The other end is fixed by spring bolt, and the elastic force that spring provided plays and reduces function of friction between a yarn and the groove drum.The problem that this common structure exists is following: because the attachment point position of both ends of the spring is non-adjustable, so the elongation of spring can not be adjusted.The friction force size that yarn produced for different cultivars is consistent relatively, and this causes when product changes, and quality is wayward.As the cotton knot hyperplasia rate of cotton yarn have only 30% and wash/cotton blending cotton knot hyperplasia rate 90%, a day traditional instrument fiber increase cotton knot and give birth to rate 150%; The cotton knot hyperplasia is except outside the Pass having with the fiber self character; Directly related with the friction force that receives in the yarn winding process, and this friction force is size-controlled in the pulling force of spring.Therefore, according to product performance, the elongation of adjustment contact pressure control setup medi-spring is the key that addresses the above problem.
The utility model content
The utility model is used to overcome the defective of prior art and provides a kind of spring elongation can be according to the automatic winding machine barrel yarn contact pressure control setup of product performance adjustment.
The alleged problem of the utility model is that following technical scheme solves:
A kind of automatic winding machine barrel yarn contact pressure control setup; It is positioned at the transmission case body of automatic winder, and its formation comprises curved rod, articulation piece, main shaft, tube yarn count arm and spring, and an end of its medi-spring is connected with curved rod; The other end is fixed by spring bolt; Spring bolt and casing screw, and special feature is: said spring bolt head is provided with eccentric platform, and said spring one end is sleeved on this off-centre platform.
Above-mentioned automatic winding machine barrel yarn contact pressure control setup, the eccentric throw at said eccentric platform to spring bolt center is the 10-15 millimeter.
Above-mentioned automatic winding machine barrel yarn contact pressure control setup is provided with the adjustment mark on the casing of spring bolt periphery.
Above-mentioned automatic winding machine barrel yarn contact pressure control setup, the eccentric platform of said spring bolt is provided with the extension spring groove, and the afterbody of said spring bolt is provided with adjustment mounting board face.
The utility model improves to the problem that automatic winding machine barrel yarn contact pressure control setup spring elongation can not preset, and the structure of spring one side connecting element spring bolt is improved, and at its head eccentric platform is set; Spring one end is sleeved on this off-centre platform; When needs adjustment spring elongation, trip spring bolt jam nut, rotating spring bolt of rear end plate; Promptly can be easily the elongation of spring be carried out preset, to satisfy the production requirement of different cultivars yarn.The utility model is simple in structure, is skillfully constructed, and has solved the problem of long-term puzzlement automatic winder yarn production quality fluctuation with the improvement project of more or less freely realization.

Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of spring bolt;
Fig. 3 is the left view of Fig. 2;
Fig. 4 is the birds-eye view of Fig. 2.
Label is represented as follows in the accompanying drawing: 1. groove drum, 2. a yarn, 3. a yarn count arm, 4. transmission case body, 5. main shaft; 6. curved rod, 7. articulation piece, 8. adjustment mark, 9. spring; 10. spring bolt, the eccentric platform of 10-1., 10-2. hangs spring groove, and 10-3. adjusts the mounting board face.
The specific embodiment
Referring to Fig. 1, the said automatic winder thread tension device of the utility model, it is positioned at the transmission case body 4 of automatic winder, and its formation comprises curved rod 6, articulation piece 7, main shaft 5, tube yarn count arm 3 and spring 9.Articulation piece and main shaft install and are synchronized with the movement, and tube yarn count arm is sleeved on the main shaft, and curved rod and articulation piece are fixed, and an end of spring 9 is connected with curved rod, and the other end is fixing by spring bolt 10, and spring bolt and transmission case body 4 screw.Spring force is granted main shaft 5 through curved rod, makes main shaft receive right handed moment, thereby makes a yarn count arm 3 reduce the pressure to tube yarn 2.For spring force can be adjusted according to yarn product is different, the head of the said spring bolt 10 of the utility model is provided with eccentric platform 10-1, and said spring 9 one ends are sleeved on this off-centre platform.
Referring to Fig. 1-4, eccentric platform 10-1 is the 10-15 millimeter to the eccentric throw at spring bolt center, and rotating spring bolt 10 can change the distance between 9 liang of attachment points of spring, thus the elastic force of adjustment spring.For the adjustment that makes spring bolt quantizes, adjustment mark 8 is set on the casing of spring bolt 10 peripheries.On the eccentric platform 10-1 of spring bolt, be provided with the extension spring groove 10-2 of being convenient to fixing spring, be provided with adjustment mounting board face 10-3 at the afterbody of spring bolt.When the utility model uses; Trip spring bolt jam nut (not shown); Adjustment mounting board face 10-3 with spring 10 steps up to rotate with spanner; Adjust the identification of position adjustment amount of mark relatively according to products characteristics and eccentric platform 10-1,, make the pressure of 1 of a yarn 2 and groove drum satisfy the yarn product characteristics through adjustment spring elongation.
