Description
Technical field
The utility model relates to a kind of Sewing machines parts, particularly a kind of multineedle sewing machine bottom line take-up device.
Background technology
Multineedle sewing machine is a kind of chain sitch sewing machine that can adorn some pins.Upper thread of every pin band pass sewing and corresponding looper with bottom line be intertwined to form double chainstitch.Such as, the machine of 12 pins just has 12 pins and 12 loopers, and 12 upper threads and 12 foundation lines are also just arranged, and can stitch out 12 chain-type stitchs during work simultaneously.Multineedle sewing machine is provided with upper thread take-up device and bottom line take-up device, plays the wire loop that tightens up separately and pulls out the effect of one section reserve suture there from a ball of string separately, and reserve suture is required for next pin of seam, and the length of reserve suture is called the take-up amount.
Existing bottom line take-up device as shown in Figure 1, its design feature is on the take-up frame 4 two to be crossed line plates 6 and is parallel to each other, crossing on the line plate 6 respectively has several cable-through holes 7, all bottom lines 8 all are respectively from 7 li passing of being parallel to each other of these several cable-through holes.During work, thread take-up tension lever 3 swings up and down around thread taking-up axle 2, to lower swing the time, thread take-up tension lever 3 pulls down some foundation lines 8, plays the effect of bottom line 8 being tightened up and pulling out from a ball of string one section suture there, as can be seen from Figure 1, be drawn out come less apart from the near bottom line 8 in thread taking-up axle 2 (failing among Fig. 1 to draw) axle center, and be drawn out come more, make the tightness of stitching inconsistent apart from thread taking-up axle 2 axle center bottom line 8 far away, cause bottom line tension to have nothing in common with each other, influenced sewing efficiency.
Summary of the invention
The purpose of this utility model is to cause bottom line tension to have nothing in common with each other influence the defective of sewing efficiency in order to overcome existing bottom line take-up device, thereby two mistake line plates inventing on a kind of take-up frame have an angle to make the take-up amount approximately equal of many foundation line make the multineedle sewing machine bottom line take-up device of the tightness unanimity of stitching.
The purpose of this utility model is to realize by following technical scheme: described multineedle sewing machine bottom line take-up device, comprise thread take-up crank, thread taking-up axle, thread take-up tension lever, take-up frame and base, base is provided with thread taking-up axle and take-up frame, thread taking-up axle is provided with thread take-up crank, one end of thread take-up tension lever is located on the thread take-up crank, the take-up frame comprises that two are crossed the line plate, the other end of thread take-up tension lever is located at two and is crossed between the space of line plate, cross several cable-through holes are respectively arranged on the line plate, all bottom lines all are passing of being parallel to each other in these several cable-through holes respectively, it is characterized in that: crossing for two on the take-up frame has an outwards open angle α between the line plate, correspondence two pitchs of holes near apart from the thread taking-up axle axle center are little, and correspondence two pitchs of holes far away apart from the thread taking-up axle axle center are big.
Described take-up frame is to be screwed on base, and the take-up frame can be regulated in vertical direction.
Described some cable-through holes of crossing on the line plate can be point-blank, also can be not point-blank.
The spacing of the some cable-through holes on the line plate is crossed in described the same side, can equate, also can be not unequal.
Good effect of the present utility model is as follows: because two on the take-up frame have an outwards open angle excessively between the line plate, no matter so can make the bottom line take-up amount far away or near can both approximately equal apart from the thread taking-up axle axle center, thereby the consistent stitching of the tightness of guaranteeing stitching is more attractive in appearance, guarantee that bottom line tension is identical, has improved sewing efficiency.

The specific embodiment
As shown in Figure 2, described multineedle sewing machine bottom line take-up device, comprise thread take-up crank 1, thread taking-up axle 2, thread take-up tension lever 3, take-up frame 4 and base 5, base 5 is provided with thread taking-up axle 2 and take-up frame 4, thread taking-up axle 2 is provided with thread take-up crank 1, one end of thread take-up tension lever 3 is located on the thread take-up crank 1, take-up frame 4 comprises that two are crossed line plate 6, the other end of thread take-up tension lever 3 is located at two and is crossed between the space of line plate 6, cross several cable-through holes 7 are respectively arranged on the line plate 6, all bottom lines 8 all are respectively from 7 li passing of being parallel to each other of these several cable-through holes, it is characterized in that: crossing for two on the take-up frame 4 has an outwards open angle α (see figure 3) between the line plate 6, correspondence two pitchs of holes near apart from thread taking-up axle 2 axle center are little, and correspondence two pitchs of holes far away apart from thread taking-up axle 2 axle center are big.
Described take-up frame 4 is to be fixed on the base 5 with screw 9, and take-up frame 4 can be regulated in vertical direction.
Described some cable-through holes 7 of crossing on the line plate 6 can be point-blank, also can be not point-blank;
The spacing of the some cable-through holes 7 on the line plate 6 is crossed in described the same side, can equate, also can be not unequal.
During work, because thread take-up crank is swung around thread taking-up axle, so being the line plate space spaced winding thread taking-up axle of crossing on the take-up frame, thread take-up tension lever swings up and down, all bottom lines all from right side passing of crossing that cable-through hole on the line plate is parallel to each other around to and be positioned at below the thread take-up tension lever, the cable-through hole of crossing on the line plate from the left side passes again, when thread take-up tension lever during to lower swing, just bottom line is pulled down, play the effect of bottom line being tightened up and pulling out from a ball of string one section suture there, owing to cross an outwards open angle arranged between the line plate for two on the take-up frame, no matter so can make the bottom line take-up amount far away or near can both approximately equal apart from the thread taking-up axle axle center, thereby the consistent stitching of the tightness of guaranteeing stitching is more attractive in appearance, guarantee that bottom line tension is identical, has improved sewing efficiency.
