Description
Affiliated technical field
The utility model relates to a kind of multi-head computerized embroidery machine thread cutting mechanism, specifically to the improvement of existing computer embroidering machine thread cutting mechanism.
Background technology
Existing computer embroidering machine thread cutting mechanism adopts the thread cutting mechanism of Japan " island, field " machine more.Find that through using over several years this thread cutting mechanism exists following defective: 1, the transmission of trimming camshaft is output shaft → lower shaft → sprocket wheel → chain → sprocket wheel → camshaft transmission.After use a period of time, chain produces loosening, the length lengthening, and trimming cam and lower shaft relevant position change, and the trimming moving knife produces displacement, upper thread shearing back length occurs and differs, and the bottom surface line is cut continuous phenomenon, directly influences the embroidery quality.In order to guarantee the normal operation of thread cutting mechanism, adopting method for maintaining is to regulate the tensioner sprocket wheel, but can only temporaryly deal with problems, can't fundamentally solve, and frequent shutdown maintenance, also can directly cause production efficiency to descend.2, chain drive, noise is big during the transmission of trimming case, and working environment is had certain influence.3, body structure complexity, manufacturing cost height, Installation and Debugging inconvenience.For this reason, the continuous feedback opinion of many users wishes that the innovation and creation that overcome above-mentioned defective as early as possible produce as early as possible.
Summary of the invention
The utility model is to solve the problems such as chain, the existing bottom surface of chain gear transmission line are cut constantly, the transmission noise is big that adopt.
In order to reach the purpose that solves the problems of the technologies described above, the technical solution of the utility model is: the novel thread cutting mechanism of a kind of multi-head computerized embroidery machine, it comprises thread cutting mechanism, and it is characterized in that the structure of thread cutting mechanism is: cam is contained on the lower shaft, is fixed with base on the frame, a base part is the U-shaped frame structure, the base below is provided with electromagnet, is the shift fork fulcrum post on this electromagnet, and shift fork fulcrum post shank is with spring, shift fork fulcrum post upper end connects shift fork, and shift fork one end is connected with the cam pin; The other end is a fork-shaped, and the fork-shaped end yoke of this shift fork is on a vertical shift fork power transmission shaft axis body that is provided with, and this shift fork power transmission shaft connects cutter driving axle and trimming pull bar, and these cutter driving axle two ends are versatilely in the hole of plug-in mounting base U-shaped framework biside plate.
In the utility model, also have following feature: connect an axis of guide above base U-shaped framework biside plate, shift fork power transmission shaft upper end is sleeved on the axis of guide versatilely.
In the utility model, also have following feature: described cam is a curve slot type cam.
The utility model compared with prior art has the following advantages and good effect: 1, the trimming cam directly is connected with lower shaft, synchronous when guaranteeing trimming cam and following through-drive, avoided the bottom surface line to cut continuous phenomenon, thereby guarantee embroidery trimming quality, reduce maintenance frequency, save maintenance cost, improve embroidery output.2, adopted novel trimming transmission mechanism, the transmission track is accurate, and is reliable, improved the trimming qualification rate.3, saved parts such as chain, sprocket wheel, noise decline Installation and Debugging are convenient, and case construction is simplified, and weight is existing 1/3, and manufacturing cost descends nearly 2/3.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 2 is the A-A cutaway view among Fig. 1.
1, lower shaft; 2, cam; 3, cam pin; 4, shift fork; 5, the axis of guide; 6, cutter driving axle; 7, base; 8, shift fork power transmission shaft; 9, shift fork fulcrum post; 10, spring; 11, electromagnet; 12, frame; 13, trimming pull bar; 14, thread cutting mechanism.
The specific embodiment
Referring to Fig. 1 and Fig. 2, thread cutting mechanism of the present utility model is used mark 14 chief representatives.In order to overcome the defective that existing thread cutting mechanism exists, an embodiment of the present utility model is as follows: trimming cam 2 (cam is a curve slot type cam) directly is contained on the lower shaft 1, be fixed with base 7 on the frame 12, base 7 parts are the U-shaped frame structure, the base below is provided with electromagnet 11, and these electromagnet 11 tops are shift fork fulcrum posts 9, and shift fork fulcrum post 9 shanks are with spring 10, shift fork fulcrum post 9 upper ends connect shift fork 4, and shift fork 4 one ends are connected with cam pin 3; The other end is a fork-shaped, and the fork-shaped end yoke of this shift fork 4 is on vertical shift fork power transmission shaft 8 axis bodies that are provided with, and this shift fork power transmission shaft 8 connects cutter driving axle 6 and trimming pull bars 13, and these cutter driving axle 6 two ends are versatilely in the hole of the U-shaped framework biside plate of plug-in mounting base 7.Connect an axis of guide 6 above the U-shaped framework biside plate of base 7, shift fork power transmission shaft 8 upper ends are sleeved on the axis of guide 5 versatilely.
Operation principle is as follows: after the computer that electricity takes off embroidery machine sends the trimming signal, mandrel by electromagnet 11 rises, promote to move on shift fork fulcrum post 9 and the shift fork 4, cam pin 3 is inserted in trimming cam 2 curved grooves, during 2 rotations of trimming cam, drive shift fork 4, shift fork power transmission shaft 8 swing, and drive cutter driving axle 6 again and horizontally slip in the side plate hole of base 7, thereby drive front pull bar 13 move left and right, finish the trimming function.
Because trimming cam 2 directly is contained on the lower shaft 1, its kind of drive is: output shaft → lower shaft 1 → cam 2, its drive connection is not only simplified, and transmission is accurate.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
