Description
Technical field
The utility model relates to the button holing sewing machine technical field, and particularly a kind of eyelet buttonhole sewing machine directly drives structure.
Background technology
The driving synchronizing wheel of existing button holing sewing machine brings synchronously with the common employing of lower shaft synchronizing wheel and is connected, in order to prevent that band has phenomenons such as displacement, vibration when running up synchronously, synchronous band is provided with directive wheel and transition is regulated and located to tension assembly, makes its transmission system stable.But the position of existing directive wheel and tension assembly setting has nothing in common with each other, and particularly the vertical height setting between directive wheel and the tension assembly differs, and this just badly influences the stability of synchronous band when running up.Therefore, how to guarantee that problems such as synchronous band can keep stablizing have become the much-talked-about topic of research in the industry when running up.
The utility model content
The purpose of this utility model is at the defective of prior art and deficiency, provides eyelet buttonhole sewing machine a kind of simple in structure, reasonable in design, easy to use directly to drive structure.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of eyelet buttonhole sewing machine described in the utility model directly drives structure, comprise spindle motor, drive synchronizing wheel, main shaft, synchronously band, if a directive wheel, tension assembly, lower shaft synchronizing wheel and lower shaft, the quantity of described directive wheel is two, two directive wheels are respectively directive wheel one and directive wheel two, distance between the vertical direction of described directive wheel one and directive wheel two is height one, and described height one is 18～28mm; Distance between the vertical direction of described directive wheel two and tension assembly is height two, and described height two is 25～35mm; The external diameter of described directive wheel one is greater than the external diameter of directive wheel two, and described directive wheel one is positioned at the top of directive wheel two, and described tension assembly is positioned at the below of directive wheel two.
Further, described height one is 23mm.
Further, described height two is 28mm.
After adopting said structure, the utility model beneficial effect is: a kind of eyelet buttonhole sewing machine described in the utility model directly drives structure, comprise spindle motor, drive synchronizing wheel, main shaft, synchronously band, if a directive wheel, tension assembly, lower shaft synchronizing wheel and lower shaft, the quantity of described directive wheel is two, two directive wheels are respectively directive wheel one and directive wheel two, distance between the vertical direction of described directive wheel one and directive wheel two is height one, and described height one is 18～28mm; Distance between the vertical direction of described directive wheel two and tension assembly is height two, and described height two is 25～35mm; The external diameter of described directive wheel one is greater than the external diameter of directive wheel two, and described directive wheel one is positioned at the top of directive wheel two, and described tension assembly is positioned at the below of directive wheel two.When using the utility model, compared with prior art have the following advantages:
1, the stability height of synchronous band when running up.
2, the error of this transmission mechanism is little, and mechanical breakdown is few, and noise is little, high efficiency.
Advantages such as 3, this is simple in structure, arranges rationally, and cost of manufacture is low.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Description of reference numerals:
1, spindle motor; 2, drive synchronizing wheel; 3, main shaft; 4, be with synchronously; 51, directive wheel one; 52, directive wheel two; 6, tension assembly; 7, lower shaft synchronizing wheel; 8, lower shaft.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of eyelet buttonhole sewing machine described in the utility model directly drives structure, comprise spindle motor 1, drive synchronizing wheel 2, main shaft 3, be with 4 synchronously, if a directive wheel, tension assembly 6, lower shaft synchronizing wheel 7 and lower shaft 8, connected mode between these parts is with technology is identical now, so do not do explanation one by one at this.The quantity of described directive wheel is two, and two directive wheels are respectively directive wheel 1 and directive wheel 2 52, and the distance between the vertical direction of described directive wheel 1 and directive wheel 2 52 is height one H1, and described height one H1 is 18～28mm; Distance between the vertical direction of described directive wheel 2 52 and tension assembly 6 is height two H2, and described height two H2 are 25～35mm.The external diameter of described directive wheel 1 is greater than the external diameter of directive wheel 2 52, and described directive wheel 1 is positioned at the top of directive wheel 2 52, and described tension assembly 6 is positioned at the below of directive wheel 2 52; By the directive wheels of different sizes are set, by the position of directive wheel and tension assembly 6 is set like this, this device can be controlled synchronously the balance with 4 well.
Height one H1 of the present utility model is preferably 23mm; Height two H2 of the present utility model are preferably 28mm; Like this, avoid in the past because of phenomenons such as the excessive or too small displacement that causes of the distance between the vertical direction of directive wheel and tension assembly 6 or vibrations, simultaneously can effectively control synchronous band and phenomenons such as displacement, vibration when running up, occur, further guarantee the stability of band when running up synchronously.
When using the utility model, compared with prior art have the advantage of following several respects:
1, the stability height of synchronous band when running up.
2, the error of this transmission mechanism is little, and mechanical breakdown is few, and noise is little, high efficiency.
3, this is simple in structure, reasonable in design, low cost of manufacture.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
