Abstract

The invention discloses a gold plaque and bead tube cutting device, of which a blade of a moving cutter cannot exceed the lower bottom surface of a stationary cutter, and the quality of embroidery is high. The gold plaque and bead tube cutting device comprises the stationary cutter, and the moving cutter matched with the stationary cutter, wherein the moving cutter comprises the blade and a cutter back; the moving cutter is driven by a needle bar with a needle clamp; an extension part is formed at the front end of the cutter back of the moving cutter; the end face of the extension part of the cutter back is contacted with the bottom face of the needle clamp during the descending of the needle bar; and after the moving cutter is matched with the stationary cutter so as to cut off the gold plaque or the bead tube, the end face of the extension part of the cutter back is separated from the bottom face of the needle clamp before the blade of the moving cutter and the lower bottom face of the stationary cutter are horizontal. The gold plaque and bead tube cutting device is suitable for cutting the gold plaque or the bead tube in a computer embroidery machine.

Description

Gold plaque and pearl tube cutting device

Technical field

The present invention relates to a kind of computerized emboridering machine, relate 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.

Summary of the invention

The technical problem to be solved in the present invention 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 present invention is achieved through the following technical solutions:

The moving knife that the present invention includes stationary knife, 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 present invention compared with prior art has following outstanding feature and remarkable result:

1, the moving knife blade can not surpass the stationary knife bottom surface.Since the present invention 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 present invention 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 invention;

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

The present invention is described in further detail below in conjunction with the drawings and the specific embodiments:

As shown in Figure 1 and Figure 2: the moving knife 2 that the present invention includes stationary knife 1, 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 present invention 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.
