Abstract
The utility model relates to a seal tape type cloth feeding device. A recessed space is arranged above the center of a base, and a cantilever type sewing arm is penetrated and arranged in the space. Two groups of time specified belt pulleys are respectively arranged in two bases for the time specified belt pulleys in a rotating way, and time specified belts are wrapped around the outer edges of two groups of feeding specified belt pulleys. One of the time specified belt pulleys is synchronously driven to rotate by a main shaft of sewing machinery, and the time specified belts are coated and wound at the outer edge of the cantilever type sewing arm. The device is safe and practical because the utility model can prevent clothes from being twisted, can not interfere with other sewing work because of small size, and has high cloth feeding efficiency.
Description
The utility model relates to a kind of sealing belt cloth-feeding device, and it is to be installed in edge outside the cantilevered sewing of sewing machine, so that auxiliary boom formula sewing arm carries the clothing in the sewing more efficiently in the sewing process.
Sewing machine is by the different numerous species that are divided into of the different and sewing function of its structure, wherein a kind of sewing machine is shown in Fig. 4,5, it has the purposes that sewing machine that this kind of cantilevered sewing arm B that extends from fuselage A have a cantilevered sewing arm B that extends from fuselage A can be used as blind seam, and (so-called " blind seam " is meant that the suture behind the sewing all is hidden in the clothing, the appearance of clothing is not seen suture fully, and group is referred to as " blind seam ".For example diving suit just must be with blind seam mode sewing).Because the clothing of institute's sewing is thicker, the work feed usefulness deficiency of the existing cloth feeding mechanism of sewing machine, the clothing feeding has some setbacks.
The utility model is intended to provide a kind of sealing belt cloth-feeding device, and it is with sealed design, can prevent clothing twisted into, safe and practical; And its volume is little, can not hinder other sewing work; In addition, it transfers to the trace that the utility model seals the belt cloth-feeding device from the power spindle of sewing machine, is to pass from the rear of cantilevered sewing arm, can not hinder other sewing work; Its time rule belt train convergence car pin and needle plate, the time rule belts to the work feed efficient height of clothing; Its support further has a retaining cloth sheet, and clothing can not gone in the support by strand in the sewing process.
The solution that the utility model provided is: sealing belt cloth-feeding device is to place the sewing machine with cantilevered sewing arm, and sealing belt cloth-feeding device comprises: support, and it has: the space of notch, cantilevered sewing arm is placed through in the space of this notch; Rule belt wheel seat takes shape in the front and back in the space of aforementioned notch respectively in the time of two; The rule belt pulley changes respectively when being located at aforementioned two in the rule belt wheel seat in the time of two groups, and wherein the rule belt pulley is subjected to the driving of aforementioned sewing machine and cooperates sewing action rotation one the time; The time rule belt rule belt pulley outer rim in the time of two groups of unrolling, and be subjected to the driving of aforementioned time rule belt pulley and reverse, and the time rule belt pulley rotation that drives other, the rule belt pack is around in the outer rim of cantilevered sewing arm when aforementioned, the rule belt slides through above the cantilevered sewing arm when making, so that be equipped with, the clothing between compress pin and time rule belt is carried feeding in the compress pin of cantilevered sewing arm top.
Aforesaid sealing belt cloth-feeding device, rule belt passage space when wherein aforementioned support further has, this time rule belts passage space when being arranged at two between the rule belt wheel seat, the time rule belts travel passage space.
Aforesaid sealing belt cloth-feeding device, wherein aforementioned support further has a retaining cloth sheet, this retaining cloth sheet is arranged at the driving that is subjected to aforementioned sewing machine and cooperates the radially position of rule belt pulley in the sewing action rotation, and advise edge outside the belt pulley when giving prominence to this and extend into support, clothing can not gone in the support by strand in the sewing process.
After adopting said structure, the sealing belt cloth-feeding device that the utility model provided has following effect and characteristics:
1, it is with sealed design, can prevent clothing twisted into, safe and practical;
2, its volume is little, can not hinder other sewing work;
3, it transfers to the trace that the utility model seals the belt cloth-feeding device from the power spindle of sewing machine, is to pass from the rear of cantilevered sewing arm, can not hinder other sewing work;
4, its time rule belt pulley convergence car pin and needle plate, the time rule belts to the work feed efficient height of clothing;
5, its support has a retaining cloth sheet, the radially position of rule belt pulley when this retaining cloth sheet is arranged at, and outstanding this time rule belt pulleys outside edge and extend into support, clothing can not be twisted in the support in the sewing process.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the three-dimensional combination figure of the utility model, but enclosing cover is removed;
Fig. 2 is the three-dimensional exploded view of the utility model;
Fig. 3 is the three-dimensional combination figure of the utility model;
Fig. 4 is the stereogram during actual the use for the utility model is installed on the sewing machine;
Fig. 5 is from the seen side view of Fig. 4.
See also shown in Fig. 1-5, the sealing belt cloth-feeding device 10 that the utility model provided is installed on the sewing machine A with cantilevered sewing arm B, and sealing belt feeds device 10 comprises: support 11, rule belt pulley 12a, 12b in time advise main members such as belt 13 two groups the time.Wherein support 11 has: rule belt wheel seat 15a, 15b when the space 14 of notch and two.Wherein the space 14 of this notch is placed through therebetween for cantilevered sewing B.Rule belt wheel seat 15a, 15b then take shape in the front and back in the space 14 of aforementioned notch respectively in the time of two. Rule belt pulley 12a and 12b advise among belt wheel seat 15a, the 15b when then commentaries on classics is located at aforementioned two respectively during as for aforementioned two groups.The main shaft of aforementioned sewing machine A drives variable-speed motors 22 via time rule skin seat 24, and variable-speed motor 22 drives wherein one by connecting rod 23 again and is positioned at the time rule belt pulley 12a of cantilevered sewing arm B behind the time and cooperates the action of Sewing machines and rotation synchronously.13 of belts of the time rule outer rim of in the time of two groups rule belt pulley 12a, 12b of unrolling is reversed so that be subjected to the driving of rule belt pulley 12a when aforementioned, and rule belt pulley 12b rotation when driving other.Rule belt 13 is paperwrapped in the outer rim of cantilevered sewing arm B when aforementioned, rule belt 13 slides through above the cantilevered sewing arm B when making, so that be equipped with, the clothing D between compress pin C and time rule belt 13 is carried feeding forward in the compress pin C of cantilevered sewing arm B top.
Rule belt passage space 16 when support 11 further has, this time rule belts passage space 16 when being arranged at two the rule belt pass between wheel seat 15a, the 15b, for the time rule belts 13 travel therebetween.
