Abstract
The utility model discloses a sewing machine synchronous belt tension device which is characterized in that the main component is a tensioner component which consists of a tensioner pedestal, a tensioner bearing bracket, an adjusting bolt, a pedestal pin, a gasket, a bearing, a bearing pin, a pin fixing bolt and a tensioner installing bolt. The tensioner component is installed inside a sewing machine head, and the adjusting bolt is used for adjusting the position of the bearing to adjust the tightness degree of a synchronous belt. When the synchronous belt is too loose, an inner hexagon spanner is used for rotating the adjusting bolt and rotates clockwise to ensure that the synchronous belt gets more and more tight, and on the contrary the synchronous belt gets more and more loose. The required tightness degree of the synchronous belt can be achieved, and the sewing machine synchronous belt tension device ensures that the rotation driven by the synchronous belt is stable and a rotating shuttle takes up thread stably, so as to improve the product quality.
Description
Technical field
A kind of guiding mechanism and method of adjustment when the utility model relates to the synchronous band of Sewing machines than pine are specifically related to a kind of Sewing machines and are with adjustable tensioning apparatus synchronously.
Background technology
Using synchronously now, the Sewing machines of band all may produce the synchronous band phenomenon of pine excessively, be with when pine when synchronous, the rotation of transmitting will be unstable, thereby cause the rotational hysteresis of Sewing machines lower shaft, be with nonsynchronous phenomenon synchronously, when synchronous band is unstable, can produces rotating shuttle and collude the line instability, thereby bouncing pilotage broken string phenomenon takes place, so just the product quality to the client produces certain influence, and also the quality reputation to Sewing machines has produced inevitable influence.When the synchronous band of needs was longer, the assembly unit of Sewing machines, the quality of being with synchronously all can cause the loose excessively of synchronous band, and be inevitable.
Therefore, the tightness of how regulating synchronous band by a kind of guiding mechanism and method of adjustment just becomes the improved importance of present Sewing machines.
The utility model content
The utility model is to provide a kind of Sewing machines to be with adjustable tensioning apparatus synchronously, solve Sewing machines because assembly unit and synchronously band length produce be with loose phenomenon synchronously, thereby make the degree of tightness energy free adjustment of synchronous band, reach the demand of assembling, satisfy the designing requirement of Sewing machines.
Goal of the invention of the present utility model is achieved by the following technical solution:
A kind of Sewing machines is with adjustable tensioning apparatus synchronously, comprises regulating wheel base 3, tension wheel shaft bolster 6, adjustment screw 5, heel pin 7, pad 8, bearing 9, bearing pin 10, pin hold-down screw 11 and mounting screw 4; Described bearing 9 is formed the rotating group component with bearing pin 10, is installed in by bearing pin 10 in the C hole of tension wheel shaft bolster 6 bottoms, by pin hold-down screw 11 location; Described tension wheel shaft bolster 6 is installed in by the heel pin 7 of being located at top and constitutes the rotating mechanism of tension wheel shaft bolster 6 around heel pin 7 in the B hole of regulating wheel base 3; Described heel pin 7 usefulness pin hold-down screws 11 are fixing, integrant thus tensioner apparatus assembly 2.
Described adjustment screw 5 is installed on the regulating wheel base 3.
Described tensioner apparatus assembly 2 usefulness mounting screws 4 are fixed on the head of sewing machine 1.
Use this Sewing machines to be with adjustable tensioning apparatus synchronously, during pine, screw 5 is adjusted in turn at synchronous band, and the synchronous band degree of tightness that can obtain requiring makes the slow-roll stabilization of synchronous band transmission, and rotating shuttle colludes line stabilization, thereby improves the quality of products.
Description of drawings
Fig. 1 is an installation diagram of the present utility model;
Fig. 2 is the installation diagram of the utility model on Sewing machines;
Among the figure: 1-head of sewing machine 2-tensioner apparatus assembly 3-regulating wheel base 4-mounting screw 5-adjusts screw 6-tension wheel shaft bolster 7-heel pin 8-pad 9-bearing 10-bearing pin 11-pin hold-down screw
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Described a kind of Sewing machines is with tensioning apparatus when mounted synchronously, at first tension wheel shaft bolster 6 usefulness heel pins 7 are installed on the hole B of regulating wheel base 3, the two ends of heel pin 7 are concordant with the end flat of regulating wheel base 3, and it is fixing with pin hold-down screw 11, bearing 9 (two) and pad 8 are also together, be installed in bearing pin 10 on the hole C of bearing bracket stand 6, the two ends of bearing pin 10 are concordant with the end flat of bearing bracket stand 6, and with pin fixedly two ends 11 are fixing, to adjust screw 5 and be installed on the regulating wheel base, like this, just form tensioner apparatus assembly 2, at last, tensioner apparatus assembly 2 is fixed on the head of sewing machine with mounting screw 4 by diagram.
Described Sewing machines is to adjust like this with tensioning apparatus synchronously: when synchronous when being with pine, adjust screw 5 with inner hexagon spanner by the hole A turn on the Sewing machines, turn can make synchronous band more and more tighter clockwise, otherwise, synchronous band pine more and more is adjusted to synchronous band degree of tightness and satisfies specification requirement and get final product.
