Description
Technical field
The utility model belongs to field of mechanical technique, relates to the thread cutting device of a kind of Sewing machines, particularly a kind of cylindrical sewing machine.
Background technology
Sewing machines is extensive use of as a kind of machine of making.Usually, Sewing machines is whenever being made after one section and need unnecessary line cut off with scissors, and therefore, the operator also will hand scissors in addition line is cut off in using the Sewing machines process.As its inconvenient operation of domestic consumer is clearly, in addition, can obviously reduce production efficiency like this for industrial sewing machines.And, also can damage because of carelessness if use in the scissors process the operator.
For this reason, people make various improvement to Sewing machines, and as " a kind of miniature Sewing machines that tangential knife is housed " that China Patent No. 200420072065.9 provides, it is installed in tangential knife in the head dead ahead of Sewing machines.The operator is in the process of using Sewing machines, and the line that will cut off is drawn in the tangential knife place, thereby line is cut off.As can be seen, this Sewing machines does not need to use scissors.But,, might run into tangential knife when the operator pulls the cloth that need make and hurt the operator because tangential knife is positioned on the head.In addition, operator's arm must lift the head place that line could be drawn in Sewing machines top line is cut off when tangent line, works long hours to cause arm to be ached or tired.Therefore, its result of use still is undesirable.
Existing other Sewing machines also exists similar problem.
Summary of the invention
The purpose of this utility model is at existing in prior technology the problems referred to above, and a kind of thread cutting device of safe, cylindrical sewing machine that production efficiency is high is provided.
The purpose of this utility model can realize by following technical proposal: a kind of thread cutting device of cylindrical sewing machine, this Sewing machines comprises the head on top and the horn of bottom, described horn and feed direction approximate vertical, this thread cutting device comprises thread cutter, it is characterized in that described thread cutter is loaded on the edge with the horn of operator's opposition side.
In the cylindrical sewing machine of the thread cutting device that this cylindrical sewing machine is housed, cloth that needs are made etc. is placed on the horn, by the suture needle that is connected with line on the head cloth is made then.Because the operator is in using the process of Sewing machines, other situation sets about generally can not reach on the horn edge with operator's opposition side during except the need secant, and such structure makes operator's hand in the sewing process can not touch thread cutter.Certainly, the thread cutter place that in the time of line need being cut off line is drawn in the horn edge gets final product.
In the thread cutting device of above-mentioned cylindrical sewing machine, described horn upper surface is equipped with the needle plate fishplate bar, and described thread cutter is loaded on the edge of needle plate fishplate bar.Because thread cutter is positioned at needle plate fishplate bar edge, when needing in the process of making in case after finishing one section unnecessary line cut off, the thread cutter place that line is drawn in needle plate fishplate bar edge just can cut off it.
In the thread cutting device of above-mentioned cylindrical sewing machine, described thread cutter is made up of the edge of a knife and connecting portion, and the edge of a knife is〉shape, connecting portion is connected on the needle plate fishplate bar by screw.
In the thread cutting device of above-mentioned cylindrical sewing machine, described needle plate fishplate bar edge is provided with recess, and the edge of a knife of above-mentioned thread cutter has the gap between indent and the recess and the edge of a knife.Gap between the recess and the edge of a knife makes line can enter the knife-edge part of thread cutter.In the process of making, the line that needs cut off is drawn in indent, the thread cutter by indent just can cut off line.
In the thread cutting device of above-mentioned cylindrical sewing machine, the top of described thread cutter is provided with the convex shoulder of protrusion, described needle plate fishplate bar edge is provided with recessed secant tool rest near indent, the secant tool rest is provided with recessed convex shoulder seat, and above-mentioned thread cutter is loaded in the secant tool rest and the convex shoulder of thread cutter is positioned at the convex shoulder seat.The connecting portion that screw passes thread cutter is connected in thread cutter in the secant tool rest, simultaneously the convex shoulder on the thread cutter cooperates with convex shoulder seat on the secant tool rest and makes that thread cutter is connected on the needle plate fishplate bar firmly, avoids thread cutter to swing around the junction of it and needle plate fishplate bar.
Compared with prior art, the thread cutting device of this cylindrical sewing machine is owing to be installed in thread cutter on the edge with the needle plate fishplate bar of operator's opposition side, and operator's hand generally can not reach on the needle plate fishplate bar edge with its opposition side in the sewing process.Like this, the knife-edge part of in the time of need cutting off line line being drawn in thread cutter gets final product, and because the edge of a knife is in the opposite side of operator, the operator is difficult for touching thread cutter in the process of using Sewing machines, makes that the safety in utilization of Sewing machines is higher.Simultaneously, when needing secant line is drawn in indent along the needle plate fishplate bar and get final product, whole process is simple fast, makes that the operating efficiency of Sewing machines is higher.

Fig. 2 is the syndeton schematic diagram of thread cutter and needle plate fishplate bar in the thread cutting device of this cylindrical sewing machine.
Fig. 3 is the perspective view of thread cutter in the thread cutting device of this cylinder-shaped sewing machine.
Among the figure, 1, thread cutter; 11, the edge of a knife; 12, connecting portion; 13, convex shoulder; 2, head; 3, needle plate fishplate bar; 31, recess; 32, secant tool rest; 321, convex shoulder seat; 4, screw; 5, horn.
The specific embodiment
As shown in Figure 1, cylindrical sewing machine is made up of head 2 and horn 5, and head 2 is positioned at the top of cylindrical sewing machine, and horn 5 is positioned at its underpart.Horn 5 and feed direction approximate vertical, the upper surface of horn 5 is equipped with needle plate fishplate bar 3.
The thread cutting device of this cylindrical sewing machine comprises thread cutter 1, and thread cutter 1 is loaded on the edge of needle plate fishplate bar 3 of cylindrical sewing machine.And thread cutter 1 is on the needle plate fishplate bar 3 of operator's opposition side.
As shown in Figures 2 and 3, thread cutter 1 is made up of the edge of a knife 11 and connecting portion 12, and the edge of a knife 11 is〉shape, connecting portion 12 is connected on the needle plate fishplate bar 3 by screw 4.
Needle plate fishplate bar 3 edges are provided with recess 31, are close to recess 31 places and also are provided with recessed secant tool rest 32, and secant tool rest 32 is provided with recessed convex shoulder seat 321.The top of above-mentioned thread cutter 1 is provided with the convex shoulder 13 of protrusion.After the connecting portion 12 of thread cutter 1 was connected in secant tool rest 32 on the needle plate fishplate bar 3 by screw 4, the convex shoulder 13 on the thread cutter 1 also was positioned at the convex shoulder seat 321 of secant tool rest 32 simultaneously.Simultaneously, the edge of a knife 11 of thread cutter 1 is in recess 31 places, and has the gap between the edge of a knife 11 and the recess 31.
As can be seen, thread cutter 1 can not swung around screw 4 after being connected in needle plate fishplate bar 3 edges by said structure, thereby has improved the stability in use of cylindrical sewing machine.
When use had the cylindrical sewing machine of this thread cutting device, cloth that needs are made etc. was positioned on the needle plate fishplate bar 3, just can make it by the suture needle on the head 2.When making when needing after one section unnecessary line cut off, line to be drawn in the recess 31 along needle plate fishplate bar 3, thread cutter 1 edge of a knife 11 at recess 31 places just can cut off line.
