Abstract
Disclosed is a wear-reduction yarn selecting mechanism for a sewing machine. The technical proposal is that a sleeve connected with a pendulum block is nested on a thread-taking-up shaft; the lower end of the thread-taking-up shaft passes through a through hole arranged on the pendulum block, and is movably connected with a beating plate in a plug pin type; the pendulum block is hinged with one end of the beating plate; a triangle hook is fixed on the other end of the beating plate; a set of bearings for connecting the beating plate and the pin on the thread-taking-up shaft are arranged in a chute where the beating plate and the thread-taking-up shaft are movably connected; and a set of bearings for hinging the beating plate and the pin on the pendulum block are arranged in a through hole where the beating plate and the pendulum block are hinged with each other. With such structure, the sliding friction between the beating plate and the pin connected with the beating plate is changed into the rolling friction by means of the bearings, which reduces the wearing among parts, effectively prolongs the service life of the parts and improves the working precision of the triangle hook.
Description
Technical field:
The utility model relates to technical field of knitting machinery, refers in particular to a kind of anti-attrition yarn taking-up device of sewing machine.
Background technology:
Sewing machine is one of visual plant of woolens industry, and it is in order to sew up knitting garment piece, neck, cuff etc.In order to simplify the structure of sewing machine, improve the operating efficiency of sewing machine, people have done a lot of effort, have obtained very big effect.But along with the continuous appearance of novel chemical ﹠ blended fabric and the continuous variation of people's demand, the performance of sewing machine has also been proposed more and more higher requirement, original various sewing machine structures are showed its drawback gradually.See accompanying drawing 1,2, this is the stereogram of yarn taking-up device and its three-dimensional exploded view of present a sewing machine, mainly carries out two kinds of motion modes during its work simultaneously and drives and be fixed on the triangle hook of beating on the sheet 05 06 and carry out compound motion, finishes and chooses the yarn action.Its motion mode is a kind of to be that sleeve 02 drives centering block 03 swing; It two is that sliding sleeve 01 drives thread taking-up axle 04 and moves up and down, and drives simultaneously with the hinged sheet 05 of beating of thread taking-up axle 04 and move up and down.Sheet screw 07 is connected by beating for an end of beating sheet 05 and centering block 03, its with thread taking-up axle 04 between be connected for the bearing pin of slip, promptly offer a chute 051 on the sheet 05 beating, play sheet screw 08 and pass thread taking-up axle 04 and chute 051 respectively, thread taking-up axle 04 can be driven play sheet screw 08 along sliding in the chute 051.So, beat the through hole of offering on the sheet 05 052 and beat and be sliding friction between the sheet screw 07, also be sliding friction between the sheet screw 08 and play the chute of offering on the sheet 05 051 and beat, because the coefficient of sliding friction is bigger,, will cause the wearing and tearing of playing sheet screw 07,08 if service time is long slightly, cause the situation of the excesssive gap that cooperation occurs, to directly influence the operating accuracy of triangle hook 06, thereby caused phenomenons such as bouncing pilotage, influenced the quality of product.
Summary of the invention:
The purpose of this utility model provides a kind of minimizing to play through hole and chute on the sheet and beats the anti-attrition yarn taking-up device of the sewing machine of abrasion between the sheet screw with regard to being to overcome the defective of prior art.
The utility model is achieved by the following technical solution: sliding sleeve is connected on the thread taking-up axle, jacket casing is located on the thread taking-up axle, sleeve is connected with centering block, the lower end of thread taking-up axle is passed the through hole of offering on the centering block and is played the flexible connection that sheet is a pin type, centering block with beat sheet one end and be hinged, triangle hook is fixed on the other end of beating sheet, be built-in with one and be set in the bearing that is used to be connected on the bearing pin of beating sheet and thread taking-up axle playing chute that sheet and thread taking-up axle flexibly connect, be built-in with one and be set in the bearing that is used on the hinged bearing pin of beating sheet and centering block beating through hole that sheet and centering block be hinged.
After adopting this structure, will beat sheet and beat between the sheet screw by bearing is sliding friction, changes rolling friction into, has reduced the mutual wearing and tearing between the part, can effectively increase the service life, and has improved the operating accuracy of triangle hook.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the stereogram of existing product;
Fig. 2 is the three-dimensional exploded view of existing product;
Fig. 3 is a stereogram of the present utility model;
Fig. 4 is a three-dimensional exploded view of the present utility model.
The specific embodiment:
See accompanying drawing 3,4, the utility model comprises: sliding sleeve 1, sleeve 2, centering block 3, thread taking-up axle 4 and beat sheet 5.Sliding sleeve 1 is connected on the thread taking-up axle 4, sleeve 2 is set on the thread taking-up axle 4, sleeve 2 is connected with centering block 3, the lower end of thread taking-up axle 4 is passed the through hole of offering on the centering block 3 and is beaten sheet 5 and is the flexible connection of pin type, its concrete structure is: the bottom 41 of thread taking-up axle 4 offers a groove, beating sheet 5 parts places in this groove, offer a chute 51 on the sheet 5 beating, play sheet screw 71 and pass part and the chute 51 that groove is offered in thread taking-up axle 4 bottoms 41 respectively, with thread taking-up axle 4 with beat sheet 5 and be connected, and in playing the chute 51 that sheet 5 and thread taking-up axle 4 flexibly connect, a bearing 7 is installed, its sheathed with beat on the sheet screw 71.
Centering block 3 with beat sheet 5 one ends and be hinged, triangle hook 6 is fixed on the other end of dozen sheet 5.Centering block 3 and beat between the sheet 5 by playing sheet screw 81 hinged, playing sheet screw 81 passes the through hole of offering on the centering block 3 31 respectively and beats the through hole of offering on the sheet 5 52, with centering block 3 with beat sheet 5 and couple together, one bearing 8 is installed in beating the through hole 52 that is hinged between sheet 5 and the centering block 3, and bearing 8 is set in to be beaten on the sheet screw 81.
Originally be that utility model is when work, it mainly drives centering block 3 swings by sleeve 2 and sliding sleeve 1 drive thread taking-up axle 4 moves up and down, and drive simultaneously and drive the triangle hook of beating on the sheet 5 with hinged sheet 5 modes of moving up and down of beating of thread taking-up axle 4 and carry out compound motion, finish and choose yarn and move.
After adopting this structure, will beat sheet 5 and the sliding friction of beating between the sheet screw 71,81 changes rolling friction into, reduce the mutual wearing and tearing between the part, and can effectively prolong its service life, and improve the operating accuracy of triangle hook 6 by bearing 7,8.
