Abstract
The utility model discloses a kind of lower controlling type drag links of driving needle folder, including main crank link mechanism, compensate crank link mechanism, follower link and promotion connecting rod, the connecting rod of the compensation crank link mechanism and the connecting rod of main crank link mechanism are articulated and connected, the lower end of the connecting rod of the main crank link mechanism and follower link are articulated and connected, the upper end of the follower link and promotion connecting rod articulated connection, the casing of the front end for promoting connecting rod and head is articulated and connected, compared with prior art, noise is reduced while can be improved revolving speed and improves stability.
Description
[technical field]
The utility model relates to a kind of technical field of embroidery machine, especially a kind of lower controlling type double-crank of driving needle folder connects
The technical field of linkage.
[background technique]
Three sets of mechanisms in chain type computer embroidery machine head (shank, needle folder, presser feet) are all made of cam machine both at home and abroad at present
Structure driving.Cam mechanism operation curve is able to satisfy complete machine and runs demand to each mechanism, but the speed of service be generally 650 ~
1000 revs/min, and noise is big, and stability is poor.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of lower controlling type hyperbolic of driving needle folder
Handle link mechanism reduces noise and improves stability while can be improved revolving speed.
To achieve the above object, the utility model proposes a kind of lower controlling type drag link of driving needle folder, packets
It includes main crank link mechanism, compensation crank link mechanism, follower link and promotes connecting rod, the company of the compensation crank link mechanism
The connecting rod of bar and main crank link mechanism is articulated and connected, and the lower end of the connecting rod of the main crank link mechanism and follower link are hinged
The casing of connection, the upper end of the follower link and promotion connecting rod articulated connection, the front end for promoting connecting rod and head is hinged
Connection.
Preferably, the rear end for promoting connecting rod is connect by connecting rod with the attachment base of needle clamp mechanism.
Preferably, the crank of the main crank link mechanism and the compensation crank of crank link mechanism are incorgruous turn synchronous
It is dynamic.
The utility model has the beneficial effects that the utility model is by main crank link mechanism and compensates crank link mechanism
Cooperation driving changes follower link to the drive position for promoting connecting rod, is allowed to meet the cam mechanism fortune of driving needle clamp mechanism
The feature of moving curve reduces noise and improves stability compared with prior art while can be improved revolving speed.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]
Fig. 1 is a kind of structural schematic diagram of the lower controlling type drag link of driving needle folder of the utility model.
In figure: 1- main crank link mechanism, 2- compensation crank link mechanism, 3- follower link, 4- promote connecting rod, 5- connection
Bar, 6- attachment base.
[specific embodiment]
Refering to fig. 1, a kind of lower controlling type drag link of driving needle folder of the utility model, including main crank connecting rod machine
Structure 1, compensation crank link mechanism 2, follower link 3 and promotion connecting rod 4, the connecting rod and main song of the compensation crank link mechanism 2
The connecting rod of handle link mechanism 1 is articulated and connected, and the lower end of the connecting rod of the main crank link mechanism 1 and follower link 3 are articulated and connected,
The upper end of the follower link 3 and promotion connecting rod 4 are articulated and connected, and the casing of the front end for promoting connecting rod 4 and head hingedly connects
It connects, the rear end for promoting connecting rod 4 is connect by connecting rod 5 with the attachment base 6 of needle clamp mechanism, the main crank link mechanism 1
Crank and the synchronous incorgruous rotation of the compensation crank of crank link mechanism 2.
Utility model works process:
A kind of lower controlling type drag link of driving needle folder of the utility model during the work time, is connected by main crank
The cooperation driving follower link 3 of linkage 1 and compensation crank link mechanism 2 drives promotion connecting rod 4 to rotate upwardly and downwardly, and promotes connecting rod 4
The attachment base 6 of needle clamp mechanism is driven to move by connecting rod 5, compensation crank link mechanism 2 changes 3 pairs of promotions of follower link and connects
The drive position of bar 4 is allowed to meet the feature of the cam mechanism curve movement of driving needle clamp mechanism.
Compared with prior art, noise is reduced while can be improved revolving speed and improves stability.
Above-described embodiment is the explanation to the utility model, is not the restriction to the utility model, and any pair of sheet is practical new
Scheme after type simple transformation belongs to the protection scope of the utility model.
