Abstract
The utility model relates to a cloth (materials) feeding tooth and lift regulating device of a sewing machine. The utility model is characterized in that the cloth (materials) feeding tooth is fixed by screws and improved into a trapezoidal tenon inserting structure. When the shoving material is lifted, the trapezoidal male tenon and female tenon are squeezed to the narrow one side, and the trapezoidal male tenon and female tenon are not only loosened, but also fixed and can not be released. When fell back, the trapezoidal male tenon and female tenon can not come off because of no friction resistance. In order to achieve the perfection, the trapezoidal male tenon and female tenon are respectively provided with a fixing spiral, a stable stripe, etc. In addition, the cloth (materials) feeding tooth and lift regulating device of a sewing machine is provided with an eccentric skew shaft set of an adjustor. When a movable guard cap plate is removed, the adjustor set is exposed, and thus users can perform a try as well as adjust, and the machine body is not moved. The utility model has the advantages of convenient replacement, time saving, convenience, simplicity and high productive efficiency.
Description
The utility model relates to a kind of Sewing machines work feed (material) tooth and elevating adjusting device, and it belongs to the improvement of Sewing machines parts.
At present, Sewing machines kind both domestic and external is more, function is also many, but deficiency is must push over the body of heaviness, overturn, steeved and could operate in the bottom when adjustment feeding tooth depth is low, this brings difficulty to the worker, particularly for Sewing Machine Factory, tens, last hundreds of sewing machine is arranged, weak woman worker does not bear this kind work, needs the male mechanic who is equipped with some to carry on a shoulder pole this important task, this was both time-consuming, effort, efficient are low, uneconomical again.
The purpose of this utility model is work feed (material) tooth and the elevating adjusting device that will provide the trapezoidal tenon public affairs of a kind of improved Sewing machines work feed (material) tooth, tenon female plug to close and set up the eccentric skew shaft structure of governor, and it can solve the art existing problems effectively.
The purpose of this utility model is achieved in that a kind of Sewing machines work feed (material) tooth and elevating adjusting device, Sewing machines work feed (material) tooth is connected with a feeding tooth trailing arm 2-8, trailing arm 2-8 is connected with the public 2-5 of trapezoidal plug tenon, on the public 2-5 of trapezoidal plug tenon screw is arranged; Feeding tooth mounting seat 2-2 is arranged on feeding carriage release lever 2-1, is the female 2-3 of trapezoidal plug tenon groove in it, has the work feed tooth to stablize line 2-4 at the trapezoidal wide end of bottom land; The public 2-5 of trapezoidal plug tenon of Sewing machines work feed (material) tooth and the female 2-3 of trapezoidal plug tenon groove plug together; Governor eccentric main axis bearing holder (housing, cover) is to the half of shape poise nut cover of external welding one levelling primary spindle 1-6, half of shape poise nut overlaps overhanging terminal one and constitutes a levelling primary spindle trunnion shaft bearing sleeve 1-4, at the one-body molded eccentric skew shaft segment 1-2 that makes of eccentric skew shaft primary spindle section 1-3 right-hand member, the center of eccentric segment skew shaft and primary spindle is askew partially not to form straight line; Eccentric skew shaft primary spindle section 1-3 is limited by the eccentric skew shaft primary spindle of governor bearing holder (housing, cover) 1-4, through the half of shape poise nut cover of levelling primary spindle 1-6, connects governor primary spindle trunnion shaft bearing sleeve 1-4, keeps right at primary spindle and establishes levelling button geometrical clamp 1-7.
Owing to adopt such scheme, changed when adjusting work feed (material) tooth depth in the past and hanging down must be with upturned trouble of positive platform machine and heavy manual labor, reach save time, save trouble, saving of labor, simple and easy, purpose rapidly; This programme can make the operator take care of the adjustment machine voluntarily, does not need to establish male skilled worker in addition, so saved manpower; This product can significantly increase production efficiency and improve the quality.

Details and working condition below in conjunction with Fig. 1～concrete device that 7 detailed description foundations the utility model proposes:
This device comprises that trapezoidal tenon public affairs, the tenon female plug of eccentric skew shaft of one group of adjuster and work feed (material) tooth close structure: transfer device (ring presss from both sides) to be improved to fixedly chuck 1 of adjuster in the feeding tooth in the former sewing unit; The screw that usefulness is adjusted in former conduct up and down changes fixedly spiral shell 1-1 of adjuster into, and adjuster fixedly chuck 1 is fixed on repeatedly on the turning cylinder 18, maintains static.Adjust the half of shape poise nut cover of primary spindle 1-6 at adjuster eccentric main axis bearing holder (housing, cover) to one of external welding, the overhanging terminal one of half of shape poise nut cover 1-6 constitutes one and adjusts primary spindle trunnion shaft bearing sleeve 1-4, in order to hold in the palm the eccentric skew shaft primary spindle of flat adjuster section, make it to keep the equilbrium position constant, the one-body molded eccentric skew shaft segment of making of eccentric skew shaft primary spindle section 1-3 right-hand member, this eccentric segment axle is not because of forming straight line with the center of primary spindle is askew partially, thereby, when primary spindle rotates slightly, eccentric skew shaft segment just departs from rising or reduces, eccentric skew shaft primary spindle section 1-3 is limited by the eccentric skew shaft primary spindle of governor bearing holder (housing, cover) 1-4, the standard rotation system that the connection governor primary spindle trunnion shaft bearing sleeve 1-4 that overlaps 1-6 through the half of shape poise nut of levelling primary spindle is connected as one, its primary spindle is kept right and is established a levelling button geometrical clamp 1-7, this chuck through a levelling button cover fixedly spiral shell 1-8 fix and do not move, as levelling handle knob 1-9, to pull the left-right rotation of the eccentric skew shaft primary spindle of governor section 1-3, move to drive the off-centered of the eccentric skew shaft 1-2 of governor, reach and rise or fall, that is high or low levelling purpose.
When levelling, open the movable protecting cover plate 4 that to remove earlier, the governor lifting levelling of governor fixedly spiral shell 1-1 is exposed with levelling button handle 1-9, rotate fixedly spiral shell 1-1 of governor lifting levelling with spanner, after loosening, pulling levelling button handle 1-9 with another finger can heighten or turn down, but and tries while transferring till suitable.
Work feed (material) tooth is with integrated work feed (material) the tooth mounting seat 2-2 of the female 2-3 device of the trapezoidal plug tenon of work feed (material) tooth group on feeding carriage release lever 2-1, the trapezoidal wide end of its bottom land has work feed (material) tooth of striation to stablize line 2-4, public 2-5 inserts chase mortise imperial mother at trapezoidal plug tenon, add trapezoidal plug tenon hold-down screw 2-7, screw-in end of a year or month back is stable not to be moved; The public 2-5 of trapezoidal plug tenon outwards (right side) extends to feeding tooth trailing arm 2-8, this trailing arm and trapezoidal plug tenon public affairs and the feeding tooth three manufacturing that is formed in one, its feeding tooth 2-9 has different size because of various uses, but public 2-5 is all identical through the make that trailing arm connects for trapezoidal plug tenon, in use, can change feeding tooth 2-9 as required.The reciprocating motion of feeding tooth can not cause screw loosening and come off, because, very firm on the contrary when rising pusher, when returning, there is not frictional resistance, but for for the purpose of perfect, still establish a fixing spiral shell 2-7, stablize line 2-4 etc., to reach purpose safe against all possibilities.
