Abstract
The utility model relates to a pleating device for a sewing machine. The structure of the utility model is composed of a base, a supporting frame, a small gear, a big gear, an eccentric roller, a groove rod, a shift fork, a swing rod, a swing shaft, a perching knife seat and a perching knife. The utility model is characterized in that both ends of the groove rod can be respectively provided with strip-shaped groove holes, the eccentric roller which is fixed on the big gear is positioned in the strip-shaped groove hole of the right end of the groove rod, and a driven roller which is fixedly connected to the swing rod is positioned in the strip-shaped groove hole of the left end of the groove rod. The middle of the groove rod is fixed to the right end of the shift fork of which the top end is fixed to the base, and the left end of the shift fork is connected with an adjusting rod which is arranged on the base. The utility model can be used for adjusting the pleating depth in the course of operation.
Description
The utility model relates to a kind of tucker that is used for Sewing machines.
Sewings (as bedcover and pillowcase) is a kind of pleating trailing of normal employing in the process of making.The structure of existing sewing machine tucker comprises cam, roller, roller rod, connecting rod, channel bar, crank, balance staff, shovel seat and perching knife.Cam and Sewing machines rotating shaft are in transmission connection, one end of roller rod is fixed, the other end is installed roller, roller is pressed on the cam, the central stationary links of roller rod, and the other end of connecting rod is installed in the bar shape trench hole of channel bar, can move along slotted eye, channel bar is connected with fork, and fork is connected with balance staff again, and the other end of balance staff is installed shovel seat and perching knife.After cam is driven by the Sewing machines rotating shaft, the promotion roller moves up and down, roller rod is swung around fixed pivot, the connecting rod that is connected with roller rod promotes channel bar, make fork prop up spot wobble around balance staff, the transmission balance staff makes shovel seat and perching knife reciprocating, perching knife is sent sewing forward to continuously, finishes pleating action.Regulate the position of connecting rod in the channel bar bar shape trench hole, can change the corner size of the fork that is connected with channel bar, thereby change the reciprocating stroke of perching knife, promptly change the pleating degree of depth.The pleating degree of depth is meant the folding width of sewing between two pleats.Above-mentioned tucker can be realized pleating, but the position of connecting rod in bar shape trench hole can't change in operating process, thereby this tucker can't be regulated the pleating degree of depth in pleating process.
The purpose of this utility model provides a kind ofly can regulate the Sewing machines tucker of the pleating degree of depth in pleating process.
The structure of the Sewing machines tucker that the utility model proposes comprises base, support, pinion, gear wheel, eccentric roller, channel bar, shift fork, fork, balance staff, shovel seat and perching knife, pinion is fixed in the Sewing machines rotating shaft and with gear wheel and meshes, eccentric roller off-centre is installed on the gear wheel, balance staff is installed on support and the base, one end is connected with fork, the other end is installed shovel seat and perching knife, it is characterized in that the channel bar two ends offer bar shape trench hole respectively, the eccentric roller that is fixed on the gear wheel is arranged in channel bar right-hand member bar shape trench hole, and the return idler of fixedlying connected with fork is arranged in channel bar left end bar shape trench hole; Fix with the shift fork right-hand member in the middle of the channel bar, base is fixed on the shift fork top, and the left end of shift fork is connected with the adjusting rod that is installed on base.
The tucker that the utility model proposes not only can be realized pleating, and can regulate the pleating degree of depth in the pleating course of work.The tension and compression adjusting rod, the shift fork right-hand member is to left movement, the channel bar that is fixed in the driving lever right-hand member is also to left movement, and at this moment, the distance of return idler and channel bar fulcrum reduces, the distance of eccentric roller and channel bar fulcrum increases, the rotational angle of the fork that is connected with return idler increases, and the corner of balance staff also increases thereupon, and the reciprocating motion stroke of shovel seat and perching knife increases, so, increased the pleating degree of depth.Otherwise, push adjusting rod open, the shift fork right-hand member moves right, the distance of return idler and channel bar fulcrum increases, and the distance of eccentric roller and channel bar fulcrum reduces, and the corner of fork and balance staff diminishes like this, the reciprocating motion stroke of shovel seat and perching knife reduces, so reduced the pleating degree of depth.
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is further described.
Shown in Figure 1 is the front view of this tucker;
Shown in Figure 2 is the right view of this tucker;
Shown in Figure 3 is the left view of this tucker.
The structure of the tucker that the utility model proposes comprises base 3, support 12, pinion 1, gear wheel 2, eccentric roller 7, channel bar 5, shift fork 11, fork 6, balance staff 8, shovel seat 13 and perching knife 14, pinion 1 is installed in the Sewing machines rotating shaft and with gear wheel 2 and meshes, eccentric roller 7 off-centre are installed on the gear wheel 2, balance staff 8 two ends are installed in respectively on base 3 and the support 12, one end is connected with fork 6, the other end is installed shovel seat 13 and perching knife 14, it is characterized in that channel bar 5 two ends are respectively equipped with bar shape trench hole, the eccentric roller 7 that is fixed on the gear wheel 2 is arranged in channel bar 5 right-hand member bar shape trench holes, and the return idler 4 of fixedlying connected with fork 6 is arranged in channel bar 5 left end bar shape trench holes; Fix with shift fork 11 right-hand members in the middle of the channel bar 5, base 3 is fixed on shift fork 11 tops, and the left end of shift fork 11 is connected with the adjusting rod 9 that is installed on base 3, and shift fork 11 is equipped with back-moving spring 10, and back-moving spring 10 1 ends catch on shift fork 11, and the other end is fixed in base 3.
