Abstract

The utility model discloses a cutting-off device of gold slices and bead tubes, which has the advantages that a knife edge of a moving knife cannot go beyond the lower bottom surface of a fixed knife, and the quality of embroideries is good. The cutting-off device comprises the fixed knife, and the moving knife matched with the fixed knife, wherein the moving knife comprises the knife edge and a knife back and is driven by a needle bar provided with a needle clamp; an extension part is arranged at the front end of the knife back of the moving knife; the end surface of the extension part of the knife back can be in contact with the bottom surface of the needle clamp when the needle bar goes downwards; and when the moving knife and the fixed knife are matched to cut off the gold slices or the bead tubes and before the knife edge of the moving knife is level with the lower bottom surface of the fixed knife, the end surface of the extension part of the knife back is detached from the bottom surface of the needle clamp. The cutting-off device is suitable for cutting off the gold slices or the bead tubes in a computerized embroidery machine.

Description

Gold plaque and pearl tube cutting device

Technical field

The utility model relates to a kind of computerized emboridering machine, relates in particular to a kind of shearing device that is used for gold plaque or the cut-out of pearl pipe.

Background technology

In computerized emboridering machine gold plaque or pearl pipe anglicanum, because what transport was carried is gold plaque chain or pearl pipe chain, gold plaque chain is made up of the end to end gold plaque of slices, have only blocks of gold plaque just can be carried out gold plaque embroidery after gold plaque chain downcuts, and pearl pipe chain is made up of interconnective pearl pipe one by one, have only and just can carry out the embroidery of pearl pipe after will be one by one downcutting on the pearl Guan Congzhu pipe chain, so adopt at every turn foremost gold plaque or pearl pipe be transported to the moving knife below, make the edge of this gold plaque or pearl pipe corresponding with moving knife blade place, when moving knife descending, by moving knife with after stationary knife cooperates, this gold plaque or pearl pipe are downcut from gold plaque chain or pearl pipe chain, then gold plaque or pearl pipe are embroidered on the cloth with the embroidery pin that moving knife is simultaneously descending.Moving knife motion at present generally adopts shank to drive, promptly when shank is descending, pin folder on the shank will be run into the moving knife knife back, thereby make moving knife descending and descending along with shank, in the ordinary course of things, even surpassing the stationary knife bottom surface, the descending blade of moving knife can not run into embroidery yet, but for the combination embroidery, especially make up and comprise the rope embroidery in the embroidery, band is embroidered, beading embroidery or towel embroidery etc. because the height of embroidery is higher, make the close together of embroidery from the stationary knife bottom surface, when the moving knife blade surpasses stationary knife bottom surface position, then can make the moving knife blade cut to embroidery, cause embroidery impaired, thereby influence the embroidery quality.

The utility model content

The technical problems to be solved in the utility model provides a kind of moving knife blade can not surpass stationary knife bottom surface, the measured gold plaque of embroidery matter and pearl tube cutting device.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises stationary knife, the moving knife that matches with stationary knife, described moving knife comprises the blade and the knife back, described moving knife is driven by the shank that has the pin folder, described moving knife knife back front end is provided with extension, described knife back extension end face can press from both sides the bottom surface with pin and contact when shank is descending, when moving knife cooperates gold plaque or the cut-out of pearl pipe with stationary knife after, and before moving knife blade and stationary knife bottom surface level, described knife back extension end face and pin folder bottom surface are separated.

The utility model compared with prior art has following evident characteristic and beneficial effect:

1, the moving knife blade can not surpass the stationary knife bottom surface.Since the utility model adopts moving knife to finish gold plaque or pearl pipe cut off after, knife back extension end face is separated with pin folder bottom surface, what moving knife can be with shank is descending and descending, thereby avoids the generation of moving knife blade above stationary knife bottom surface phenomenon.

2, the embroidery quality is good.Because the utility model has avoided the moving knife blade to surpass the generation of stationary knife bottom surface phenomenon, thereby the moving knife blade can not cut to embroidery, makes the embroidery avoid impaired, guaranteed the embroidery quality.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of moving knife among Fig. 1;

Fig. 3 is the state diagram when moving knife knife back extension end face and pin folder bottom surface is separated among Fig. 1;

Fig. 4 is the state diagram when shank arrives extreme lower position among Fig. 1.

The specific embodiment

Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:

As shown in Figure 1 and Figure 2: the utility model comprises stationary knife 1, the moving knife 2 that matches with stationary knife 1, moving knife 2 comprises the blade 5 and the knife back 6, moving knife 2 is driven by the shank 8 that has pin folder 7, the moving knife knife back 6 front ends are provided with extension 9, knife back extension 9 end faces can press from both sides 7 bottom surfaces with pin and contact when shank 8 is descending, when moving knife 2 cooperates gold plaque or the cut-out of pearl pipe with stationary knife 1 after, and before moving knife blade 5 and stationary knife 1 bottom surface level, knife back extension 9 end faces and pin press from both sides 7 bottom surfaces and are separated.

Fig. 1 is to shown in Figure 4: when the utility model uses in reality, when shank descending, pin folder bottom surface on the shank contacts with moving knife knife back extension, make moving knife descending and descending along with shank, so moving knife cooperates with stationary knife, gold plaque or pearl pipe are downcut from gold plaque chain or pearl pipe chain, after gold plaque or pearl pipe cutting-off process is finished, do not come downwards to extreme lower position as yet as shank, then need continue descending, at this moment because moving knife center rotation around the shaft, moving knife knife back extension carries out circular motion with the rotating shaft center, the air line distance at moving knife knife back extension and rotating shaft center remains unchanged, but moving knife is descending, with the horizontal range at rotating shaft center then can be more and more far away, and shank is to move vertically downward, pin folder on the shank will remain unchanged with the horizontal range at rotating shaft center, shape and size design by the moving knife knife back, before moving knife blade and stationary knife bottom surface level, knife back extension end face and pin folder bottom surface is broken away from fully, even thereby shank continue descending, moving knife can be not descending thereupon yet, make the moving knife blade can not surpass the stationary knife bottom surface all the time, thereby avoid making embroidery impaired, guaranteed the embroidery quality.

Claims

1. gold plaque and pearl tube cutting device, comprise stationary knife, the moving knife that matches with stationary knife, described moving knife comprises the blade and the knife back, described moving knife is driven by the shank that has the pin folder, it is characterized in that described moving knife knife back front end is provided with extension, described knife back extension end face can press from both sides the bottom surface with pin and contact when shank is descending, when moving knife cooperates gold plaque or the cut-out of pearl pipe with stationary knife after, and before moving knife blade and stationary knife bottom surface level, described knife back extension end face and pin folder bottom surface are separated.
