Abstract
The utility model discloses an adjustable supporting device of a trimming mechanism of an automatic trimming sewing machine. The trimming mechanism comprises a movable knife used for trimming and a fixed knife arranged on the upper part of the movable knife; the movable knife is arranged on a shuttle rotating platform; the bottom of the movable knife is provided with an auxiliary supporting plate of the movable knife used for supporting the movable knife; the bottom of the auxiliary supporting plate of the movable knife is provided with a supporting pin rod used for pushing against the auxiliary supporting plate of the movable knife; the pin rod is arranged in an elastic supporting barrel with an adjustable height; a spring hole is arranged in the elastic supporting barrel along the axial direction; a spring is arranged in the spring hole; and the supporting pin rod is arranged in the spring hole. The adjustable supporting device of the utility model can lead the automatic trimming sewing machine to have reliable nip line when trimming, and can adjust the elasticity of the nip line after being used for a long time; and the trimming effect is stable.
Description
Technical field
The utility model relates to the electric sewer technical field, the concrete adjustable supporting device that relates to the thread cutting mechanism on a kind of automatic shearing Sewing machines.
Background technology
The comprehensive feeding flat seam machine of existing automatic shearing, clamp mechanism in its thread cutting mechanism is as depicted in figs. 1 and 2: moving knife auxiliary support plate 2 ' by gripper shoe spring 1 ' support, be gripper shoe spring 1 ' the A position be supported on moving knife auxiliary support plate 2 ' the B position, behind moving knife 4 ' cut line, by moving knife auxiliary support plate 2 ' with bottom line the end of a thread 3 ' be clipped in moving knife 4 ' and moving knife auxiliary support plate 2 ' between, for sewing next time ready.
After long use, gripper shoe spring 1 ' elasticity can slowly weaken, so, moving knife 4 ' and stationary knife 5 ' between pressure will reduce, cause Sewing machines trimming instability, and gripper shoe spring 1 ' elasticity reduce and also can cause clamp unreliable, sewing adverse consequences such as do not reach the standard grade once more.Gripper shoe spring 1 in this structure ' elasticity can't adjust.
The utility model content
Technical problem to be solved in the utility model is, overcomes problems of the prior art, and a kind of adjustable supporting device of automatic shearing Sewing machines thread cutting mechanism is provided.
In order to address the above problem the technical solution of the utility model is such:
A kind of adjustable supporting device of automatic shearing Sewing machines thread cutting mechanism, described thread cutting mechanism comprises a moving knife that is used for trimming, be arranged on the stationary knife on moving knife top, described moving knife is arranged on the rotating shuttle platform, described moving knife bottom is provided with a moving knife auxiliary support plate that is used to support moving knife, described moving knife auxiliary support plate bottom is provided with a support pin rod that is used to prop up the moving knife auxiliary support plate, and described pin rod is arranged in the adjustable for height resiliency supported swivel nut.
Described resiliency supported swivel nut inner shaft is provided with spring to being provided with spring eye in the spring eye, described support pin rod is arranged in the spring eye.
Described resiliency supported swivel nut is arranged on the gripper shoe spring(-supported) mount, also is provided with an adjustment screw that is used to regulate resiliency supported swivel nut elasticity on the gripper shoe spring(-supported) mount; Described gripper shoe spring(-supported) mount is fixed on the rotating shuttle platform.
Beneficial effect: clamp was reliable when adjustable supporting device described in the utility model can make automatic shearing Sewing machines trimming, and after using for a long time, can adjust the degree of tightness of clamp, the trimming effect stability.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is an existing clamp mechanism structural representation;
Fig. 2 is the partial exploded view of Fig. 1;
Fig. 3 is the structural representation of the adjustable supporting device of a kind of automatic shearing Sewing machines thread cutting mechanism described in the utility model.
Wherein 1 gripper shoe spring(-supported) mount, 2 resiliency supported swivel nuts, 3 springs, 4 support pin rod, 5 stationary knifes, 6 moving knife, 7 screws, 8 screws, 9 rotating shuttle platforms, 10 moving knife auxiliary support plates
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 3
In order to make moving knife auxiliary support plate 10 prop up moving knife 6 preferably, be provided with a support pin rod 4 in the lower end of moving knife auxiliary support plate 10, support the tongue below that pin rod 4 is supported on moving knife auxiliary support plate 10.Supporting pin rod 4 is arranged in the resiliency supported swivel nut 2, further resiliency supported swivel nut 2 inner shafts are to being provided with spring eye, be provided with spring 3 in the spring eye, described support pin rod 4 is arranged in the spring eye, support like this pin rod 4 can be in the elastic range of spring 3 wander up and down.
Described resiliency supported swivel nut 2 is arranged on the gripper shoe spring(-supported) mount 1, also be provided with one on the gripper shoe spring(-supported) mount 1 and be used to regulate the screw 8 of resiliency supported swivel nut 2 elasticities, when moving knife auxiliary support plate 10 or spring 3 takes place when lax, can further regulate resiliency supported swivel nut 2 it is moved up, move the fastening adjustment screws 8 that finishes and to fix.Described gripper shoe spring(-supported) mount 1 is fixed on the rotating shuttle platform 9 by a screw 7.
After long-time use, if it is unstable or when sewing is not reached the standard grade once more trimming to occur, can unscrew screw 8, adjust the position of supporting swivel nut 2, the pressure change that makes spring 3 is tightened screw 8 then to the requirement that needs, and realizes the trimming reliable effect of stablizing, sew.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
