Description
Technical field:
The utility model belongs to sewing device technical field, refers in particular to a kind of low noise rotating shuttle and sewing machine.
Background technique:
Rotating shuttle is most important into seam component in high-speed electronic calculator flat seam machine, and when the revolving speed of main shaft reaches 4000rpm-
When 5000rpm, the revolving speed of rotating shuttle is twice of main shaft, reaches 8000-10000rpm.Rotating shuttle is made of shuttle frame and shuttle gallbladder, and shuttle frame is solid
It is scheduled in lower axle and rotates with it, connected between shuttle gallbladder and shuttle frame with guide rail, guide-track groove, and shuttle gallbladder is fixed on chassis backplane
Location hook limit, in sewing machine work, shuttle frame high-speed rotation.
There are axial gaps for the guide rail of the guide rail of shuttle gallbladder and shuttle frame, when the shuttle gallbladder rotation opposite with high speed of shuttle frame, shuttle frame and
The shuttle gallbladder noise very big to sending there are the collision of subtle high frequency in junction, collides on axially and radially respectively.
With being increased using the time for rotating shuttle, it is further that certain abrasion axial gap occurs for the guide rail, guide-track groove between shuttle frame and shuttle gallbladder
Increase, is further increased so as to cause noise.
Summary of the invention:
The purpose of the utility model is to provide a kind of gaps by reducing between shuttle gallbladder guide rail and shuttle frame guide-track groove, prevent
Collision in axial direction is to reduce the low noise rotating shuttle and sewing machine of noise.
The utility model is realized in this way:
One of purpose of the utility model is to provide a kind of low noise rotating shuttle, including shuttle gallbladder and shuttle frame, shuttle gallbladder it is outer
It is provided with guide rail on side wall, guide-track groove is provided on the inner sidewall of shuttle frame, the shuttle Hymecromone is crossed guide rail and is arranged in guide-track groove
It is connect with shuttle frame, more than one magnet that shuttle gallbladder can be adsorbed toward bottom plate side is provided on the bottom plate of the shuttle frame.
In a kind of above-mentioned low noise rotating shuttle, the magnet is provided with two or more, using the axis line of shuttle frame as the center of circle,
It is evenly distributed.
In a kind of above-mentioned low noise rotating shuttle, there are three the magnet settings.
In a kind of above-mentioned low noise rotating shuttle, it is provided with magnet mounting hole on the bottom plate of the shuttle frame, magnet is embedded in
In magnet mounting hole.
In a kind of above-mentioned low noise rotating shuttle, the magnet is connected by close-fitting or glue is fixed on magnet mounting hole
It is interior.
Another purpose of the utility model is to provide a kind of sewing machine, including above-mentioned low noise rotating shuttle.
The advantage that the utility model protrudes compared with prior art is:
1, the utility model is adsorbed shuttle gallbladder toward the bottom plate direction of shuttle frame by the way that magnet is arranged on the bottom plate of shuttle frame, from
And the gap between shuttle gallbladder and shuttle frame and collision are reduced, reduce noise.
2, absorption of the utility model due to magnet to shuttle gallbladder, it is possible to reduce caused by the collision between guide rail and guide-track groove
Abrasion.
Detailed description of the invention:
Fig. 1 is the perspective view of the explosion of the utility model；
Fig. 2 is the top view of the shuttle frame of the utility model；
Fig. 3 is the perspective view of the shuttle frame of the utility model, and one of magnet is not installed in figure；
Fig. 4 is the schematic diagram that the utility model is mounted on chassis backplane.
In figure: 1, shuttle gallbladder；2, shuttle frame；3, guide rail；4, guide-track groove；5, bottom plate；6, magnet；7, location hook；8, magnet is installed
Hole；9, lower axle；10, chassis backplane.
Specific embodiment:
The utility model is further described with specific embodiment below, referring to Fig. 1-4:
A kind of low noise rotating shuttle, including shuttle gallbladder 1 and shuttle frame 2 are provided with guide rail 3 on the lateral wall of shuttle gallbladder 1, in shuttle frame 2
Guide-track groove 4 is provided on inner sidewall, the shuttle gallbladder 1 is connect in guide-track groove 4 with shuttle frame 2 by the setting of guide rail 3, the shuttle frame 2
Bottom plate 5 on be provided with more than one magnet 6 that shuttle gallbladder 1 can be adsorbed toward 5 side of bottom plate.Wherein, shuttle gallbladder 1 be magnetic material or
Non-magnetic material is made.When shuttle gallbladder 1 is magnetic material, there is magnetism, magnet 6 is by shuttle gallbladder 1 toward shuttle between magnet 6 and shuttle gallbladder 1
It adsorbs in 5 direction of bottom plate of frame 2.It, can be on the side adjacent with 2 bottom plate 5 of shuttle frame of shuttle gallbladder 1 when shuttle gallbladder 1 is non-magnetic material
Magnetic sheet or magnet are set, to achieve the purpose that the magnet 6 on shuttle frame 2 adsorbs shuttle gallbladder 1 toward 2 bottom plate of shuttle frame, 5 direction.
Since during sewing machine works, shuttle frame 2 is high-speed rotation, shuttle gallbladder 1 is limited by location hook 7, shuttle gallbladder 1
It is relative rotation between guide rail 3 and the guide-track groove 4 of shuttle frame 2.Under the action of magnet 6, shuttle gallbladder 1 is by the direction of past 2 bottom plate 5 of shuttle frame
Absorption, can limit the axial displacement of shuttle gallbladder 1 to a certain extent, reduce the axial gap between shuttle gallbladder 1 and shuttle frame 2, together
When also avoid that the slight collision of high frequency occurs between shuttle gallbladder 1 and the axial direction of shuttle frame 2, to reduce noise.
In the case where the guide-track groove of the guide rail 3 of shuttle gallbladder 1 and shuttle frame 2 causes axial gap to increase because of 4 abrasions, can still protect
The stability for holding the axial position of shuttle gallbladder 1 prevents collision in the axial direction, and the effect for reducing noise is more obvious.
Further, magnet 6 described in the utility model is provided with two or more, using the axis line of shuttle frame 2 as the center of circle, along week
To uniformly.
Specifically, there are three the settings of magnet 6.Certainly, one or two can be set in the magnet 6 of the utility model,
But three magnet 6 uniformly can achieve better counterbalance effect.
The mounting structure of the magnet 6 of the utility model is as follows: it is provided with magnet mounting hole 8 on the bottom plate 5 of the shuttle frame 2,
Magnet 6 is embedded in magnet mounting hole 8.
Specifically, the magnet 6 is connected by close-fitting or glue is fixed in magnet mounting hole 8.
Working principle of the utility model is:
The shuttle frame 2 of the utility model is fixed in lower axle 9, and shuttle gallbladder 1 is arranged in guide-track groove 4 by guide rail 3 to be connected with shuttle frame 2
It connects, is provided with location hook 7 on the chassis backplane 10 of 1 side of shuttle gallbladder, be arranged on shuttle gallbladder 1 fluted, the hook portion of location hook 7 is set
It sets and it is positioned in the groove of shuttle gallbladder 1.Machine spindle rotation, drives lower axle 9,2 high-speed rotation of shuttle frame, shuttle gallbladder 1
It is relative rotation between guide rail 3 and the guide-track groove 4 of shuttle frame 2.The setting of magnet 6 reduces rotating shuttle shuttle in high-speed rotation process
Because of the high frequency minor impact event occurred there are axial gap between gallbladder 1 and shuttle frame 2, to generate noise, and this advantage
It can become more to have obvious as the abrasion of rear rail 3 is used for a long time in rotating shuttle.
Above-described embodiment is only one of preferred embodiment of the utility model, and the implementation of the utility model is not limited with this
Range, therefore: the equivalence changes that all shape, structure, principles according to the utility model are done should all be covered by the guarantor of the utility model
Within the scope of shield.
