Abstract
The utility model discloses a yarn conveying device which can prevent yarns from slipping during conveyance. The device comprises a machine beam, wherein a yarn conveying roller and a leather roller are movably arranged on the machine beam and matched with each other. The yarn conveying device mainly including the yarn conveying roller and the leather roller is used for conveying yarns; after passing through the roller, the yarns are wound on the surface of the leather roller with an iron core, and the leather roller is driven to rotate at a constant speed through the friction transmission between the roller and the leather roller, so that the twisted yarns can be conveyed to a winding area under the traction force of the leather roller; and due to the sufficient driving force of the leather roller on the yarns, the yarns can be conveyed at a constant linear velocity (CLV), so as to avoid the slipping of the yarns during conveyance, as well as the twisting difference and unevenness of the yarns.
Description
Technical field
The utility model relates to the yarn-feeding devices of yarn when two-for-one twister is twisted such as a kind of polyamide fibre of weaving cord fabric, polyester filament.
Background technology
Use the twisting of double twisting technology when producing at existing industrial long filament, the yarn of having twisted is transferred to the line feeding device of winding zone, " the overfeeding wheel " on traditional twisting machine of employing.The shortcoming of this overfeeding wheel line feeding device is: skidding often takes place in yarn in the overfeeding wheel, thereby causes the transmission speed instability of yarn, and the twist that finally produces uneven twist and ingot interdigit is inconsistent.
The utility model content
Technical problem to be solved in the utility model is: the yarn-feeding device that provides a kind of yarn can not skid in course of conveying.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: yarn-feeding device, comprise the machine beam, and be movably set with the defeated leno that cooperatively interacts on the machine beam and draw and roller.
Further technical problem to be solved in the utility model is: a kind of yarn-feeding device that changes the contact position of yarn and roller is provided.
For solving above-mentioned further technical problem, the technical solution adopted in the utility model is: on the described machine beam defeated leno draw below be provided with the silk shifting rod that parallels, does axially reciprocating with roller, silk shifting rod is provided with silk shifting device, the end of silk shifting device is provided with resettlement groove, is provided with the seal wire porcelain spare that the end offers the seal wire groove in the resettlement groove.
Silk rolling guide wheel before below silk shifting device, also being provided with on the described machine beam.
The beneficial effects of the utility model are: the utility model has adopted the yarn-feeding device that mainly is made of roller and roller to fail yarn, yarn is paperwrapped in the roller surface that has iron core behind roller, by roller to the frictional drive of roller and drive the roller uniform rotation, thereby drawing twist yarn carries to the winding zone, because roller has enough driving forces to yarn, yarn is carried in the mode of permanent linear speed, thereby avoided the skidding of yarn in course of conveying, avoided the twist difference and the uneven twist of yarn; In addition, below drawing, be provided with the Traverse mechanism that mainly constitutes by silk shifting rod and silk shifting device at defeated leno, the silk shifting rod band silk shifting device axially reciprocating along roller, and then silk shifting device is reciprocating under the guiding of seal wire porcelain spare for yarn like this, constantly change the contact position of yarn and roller, so can be in a certain position grooving of roller, thus the quality of resultant yarn guaranteed; And, do not need frequent reconditioning roller yet, in the service life of both having improved roller, improved production efficiency again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation that the left apparent direction of Fig. 1 is amplified.
Among Fig. 1 to Fig. 2: 1, machine beam, 2, truss girder, 3, the air ring arresting lever, 4, support, 6, defeated leno draws, 7, roller, 8, carriage, 9, silk shifting rod, 10, silk shifting device, 15, seal wire porcelain spare, 151, the seal wire groove, 17, preceding silk rolling guide wheel, 20, yarn.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, yarn-feeding device described in the utility model, comprise: machine beam 1, be movably set with the defeated leno that cooperatively interacts on the machine beam 1 and draw 6 and roller 7, that is: defeated leno draws 6 to be parallel to each other with roller 7 and closely to contact, and wherein, the structure that specifically is provided with of roller 7 comprises: be arranged on the truss girder 2 on the machine beam 1, truss girder 2 is provided with carriage 8, and described roller 7 is movably arranged on the carriage 8; Machine beam 1 defeated leno draw 6 below be provided with the silk shifting rod 9 that parallels, does axially reciprocating with roller 7, silk shifting rod 9 is provided with silk shifting device 10, as shown in Figure 2, the end of silk shifting device 10 is provided with resettlement groove, is provided with the seal wire porcelain spare 15 that the end offers seal wire groove 151 in the resettlement groove; In the present embodiment, also be provided with support 4 on the described machine beam 1 below silk shifting device 10, support 4 is provided with preceding silk rolling guide wheel 17.
During real work, the yarn 20 of having twisted draws 6 through air ring arresting lever 3 and preceding silk rolling guide wheel 17 to defeated leno, then, is paperwrapped in the surface of roller 7.As everyone knows, a twisting mill has comprised a plurality of ingots position, each ingot position all is provided with yarn-feeding device, and, defeated leno in the yarn-feeding device on complete each ingot position of machine draws 6 by same roller shaft driving, during work, roller shaft is done uniform rotation under the drive of headstock, like this, draw 6 rollers 7 that closely contact to be subjected to the driving of frictional force and to do uniform rotation with defeated leno, and yarn 20 is paperwrapped on the roller 7 with bigger angle of contact, because the characteristic of roller 7 determines, yarn 20 is had enough tractive force, therefore, guaranteed that the constant speed of yarn 20 is carried.Yarn 20 silk rolling guide wheels 17 in the past draws to defeated leno in 6 the course of conveying, under the guiding of the seal wire porcelain spare 15 in silk shifting device 10, constantly change the contact position of yarn 20 and roller 7, so just can not be in a certain position grooving of roller 7, thus guaranteed the quality of resultant yarn; And, do not need frequent reconditioning roller 7 yet, both improved the service life of roller 7, improved production efficiency again.
