The adjusting shaft can be manually rotated, and the rotation of the adjusting shaft drives the gear, the rack and the movable yarn guide plate to move up and down, so that the tension of yarns between the upper yarn guide plate and the lower yarn guide plate is adjusted, and the loop pile size of the woven tufted blanket is consistent. Has simple structure and convenient adjustment, and ensures the quality of the tufted blanket.

Description

Position adjustable device for yarn guide plate of tufting machine

Technical Field

The utility model relates to a piece manufacturing equipment of carpet production together, in particular to adjustable device in tufting machine yarn guide plate position.

Background

Modular carpet is commonly known as "carpet tile," also known as modular carpet. The carpet is convenient to transport, install, remove and replace, and is the first choice for the carpet for business and office. A typical carpet tile is a broad carpet blank made by adhesively bonding a tufted carpet to an underlying backing material, which is then cut into smaller carpet tiles as desired. The tufting carpet is made by tufting yarn on non-woven fabric by tufting machine, the tufting on the tufting machine is mainly completed by tufting needle row, which includes straight needle with yarn moving up and down on needle board and hook moving back and forth under the needle board. During tufting, the straight needle with yarn pierces the non-woven fabric spread on the cloth supporting fork, the yarn is fed to the lower part of the non-woven fabric and hooked to form loop, i.e. the hook below the needle plate moves forward to hook the yarn, the straight needle is lifted at this moment to form loop below the non-woven fabric, and the carpet surface moves forward by one needle pitch for the next cycle. As the width of the tufted blanket is 1-2 meters, the yarn number is about thousand. In actual tufting, due to the numerous yarns, in order to prevent the yarns in the rows from being mixed together, a yarn plate guide device is adopted in the whole wire guiding process. The yarn guide plate is a plate, more than 1000 holes for single yarn to pass through are formed in the plate, and a porcelain ring is inlaid in each hole and is wear-resistant, so that the yarn can pass through smoothly. The loop pile formed by looser yarns on the straight needle is larger, and the loop pile formed by tighter yarns is smaller, so that the loop size and height on the carpet surface are different, the carpet surface style is messy, and the requirements of designers are often not met.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple structure, adjustment convenience's adjustable device of tufting machine feed carrier position.

In order to meet the requirements, the utility model discloses a realize through following technical scheme: the tufting machine is characterized in that a movable yarn guide plate with an adjustable vertical position is additionally arranged between an upper yarn guide plate and a lower yarn guide plate which are originally fixed on the tufting machine, the movable yarn guide plate is aluminum alloy angle steel, more than 1000 yarn guide holes with abrasion-resistant porcelain rings embedded in inner holes are formed in one surface of the aluminum alloy angle steel, two ends of the movable yarn guide plate are respectively fixed with a rack, the rack is pushed through a gear meshed with the rack, and the two gears are fixed on the same adjusting shaft and connected with a tufting machine frame through a shaft seat.

One end of the adjusting shaft is provided with a flat driver for rotating the adjusting shaft.

According to the device with the adjustable yarn guide plate position for the tufting machine manufactured by the scheme, the adjusting shaft can be manually rotated, the gear, the rack and the movable yarn guide plate are driven to move up and down by the rotation of the adjusting shaft, the tension of yarns between the upper yarn guide plate and the lower yarn guide plate is adjusted, and the loop pile size of the woven tufting blanket is consistent. It has simple structure, convenient adjustment and ensures the quality of the tufted blanket.

Drawings

FIG. 1 is a front view of a tufting machine guide plate position adjustment device;

fig. 2 is an enlarged right view of fig. 1.

In the figure: 1. an upper yarn guide plate; 2. a lower yarn guide plate; 3. a movable yarn guide plate; 4. a yarn guide hole; 5. a rack; 6. a gear; 7. an adjustment shaft; 8. a flat part; 9. a shaft seat; 10. a frame; 11. a yarn.

Detailed Description

The invention is further described with reference to the accompanying drawings and specific embodiments.

Fig. 1 and 2 are schematic structural diagrams of a position adjustable device of a yarn guide plate of a tufting machine. It is seen from the figure that a movable yarn guide plate 3 with adjustable up-down position is added between an upper yarn guide plate 1 and a lower yarn guide plate 2 which are originally fixed on a tufting machine, the movable yarn guide plate 3 is an aluminum alloy angle steel, one surface of the aluminum alloy is provided with more than 1000 yarn guide holes 4 with inner holes embedded with wear-resistant porcelain rings, two ends of the movable yarn guide plate 3 are respectively fixed with a rack 5, the rack 5 is pushed by a gear 6 engaged with the rack, the two gears 6 are fixed on the same adjusting shaft 7, one end of the adjusting shaft 7 is provided with a flat part 8 for rotating the adjusting shaft 7, and the adjusting shaft 7 is connected with a frame 10 of the tufting machine through a shaft seat 9. When the tension of the yarn 11 needs to be adjusted, a common wrench or a handle sleeved on the flat driver 8 can be adopted to rotate the adjusting shaft 7, the gear 6 drives the rack 5 and the movable yarn guide plate 3, so that the movable yarn guide plate 3 moves up and down, the aim of adjusting the tension of the yarn is achieved, and the yarns have similar tension.
