Abstract
The utility model discloses a kind of computerized emboridering machine head crank connecting link driving mechanisms, including main crank link mechanism, compensation crank link mechanism, follower link and lift crank link mechanism, the upper end of the connecting rod and follower link of the main crank link mechanism and compensation crank link mechanism is articulated and connected, the lower end of the follower link and the connecting rod of lift crank link mechanism are articulated and connected, compared with prior art, noise is reduced while can be improved revolving speed and improves stability, and needle top adjustment and enhanced feature can be completed, structure is simple.
Description
[technical field]
The utility model relates to a kind of technical field of computerized emboridering machine head, especially a kind of computerized emboridering machine head is used
The technical field of crank connecting link driving mechanism.
[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.
In chain type computer embroidery machine, eedle height and automatic lifting shank, needle folder, presser feet are automatically adjusted by elevator
Structure is completed, which is generally the double eccentric hoisting mechanisms of twin shaft, is only applicable to open or semi open model actuated by cams
Mechanism.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of computerized emboridering machine head crank
Bar-link drive reduces noise and improves stability, and can complete needle top adjustment and mention while can be improved revolving speed
Rise function.
To achieve the above object, the utility model proposes a kind of computerized emboridering machine head crank connecting link driving mechanism,
Including main crank link mechanism, compensation crank link mechanism, follower link and lift crank link mechanism, the main crank connecting rod
The upper end of the connecting rod and follower link of mechanism and compensation crank link mechanism is articulated and connected, the lower end of the follower link and promotion
The connecting rod of crank link mechanism is articulated and connected.
Preferably, the rear end of the connecting rod of the lift crank link mechanism and the needle bar mechanism of head connect.
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 total by main crank link mechanism and compensation crank link mechanism
It drives the connecting rod of lift crank link mechanism to rotate upwardly and downwardly with driving follower link, is driven instead of traditional cam mechanism, compensation
Crank link mechanism changes follower link to the drive position of the connecting rod of lift crank link mechanism, is allowed to meet driving shank
Cam mechanism curve movement feature；The crank rotation of lift crank link mechanism can carry out needle top adjustment and realize to be promoted
Function.Compared with prior art, noise is reduced while can be improved revolving speed and improves stability, and can complete needle to a high-profile
Section and enhanced feature, structure are simple.
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 computerized emboridering machine head crank connecting link driving mechanism of the utility model.
In figure: 1- main crank link mechanism, 2- compensate crank link mechanism, 3- follower link, 4- lift crank connecting rod machine
Structure.
[specific embodiment]
Refering to fig. 1, a kind of computerized emboridering machine head crank connecting link driving mechanism of the utility model, including main crank connecting rod
Mechanism 1, compensation crank link mechanism 2, follower link 3 and lift crank link mechanism 4, the main crank link mechanism 1 and benefit
The upper end of the connecting rod and follower link 3 of repaying crank link mechanism 2 is articulated and connected, the lower end of the follower link 3 and lift crank
The connecting rod of link mechanism 4 is articulated and connected, and the rear end of the connecting rod of the lift crank link mechanism 4 and the needle bar mechanism of head connect
It connects, the incorgruous rotation synchronous with the compensation crank of crank link mechanism 2 of the crank of the main crank link mechanism 1.
Utility model works process:
A kind of computerized emboridering machine head of the utility model with crank connecting link driving mechanism during the work time, main crank connecting rod
The incorgruous rotation synchronous with the compensation crank of crank link mechanism 2 of the crank of mechanism 1, and drive follower link 3 to move jointly, it is driven
Connecting rod 3 drives the connecting rod of lift crank link mechanism 4 to rotate upwardly and downwardly, and the connecting rod of lift crank link mechanism 4 drives needle bar mechanism
Work.The connecting rod swing that lift crank link mechanism 4 is driven by the crank rotation of lift crank link mechanism 4 realizes that needle is high
Adjust and promoted work.
Compared with prior art, noise is reduced while can be improved revolving speed and improves stability, and can complete needle
Top adjustment and enhanced feature, structure are simple.
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.
