A workbench and a cloth-downward-pulling gear are arranged on the rolling structure, the adjusting mechanism is arranged above the workbench and matched with the sensing assembly set and transmits a cloth thickness judging signal to the control unit, through electric connection of the rolling structure and the adjusting structure, pressure of the adjusting mechanism is further controlled with the match of transmission of the signal and is adjusted to be appropriate to match the speed of cloth pushing conducted by the rolling structure, so that the cloth is smoothly pushed and sewing operation is conducted and the purpose that the stitch quality is kept normal is achieved.

Description

The thick material of sewing of Sewing machines is adjusted foot pressing board device automatically

Technical field

The utility model relates to a kind of thick material of sewing of Sewing machines and automatically adjusts foot pressing board device, mainly provide a kind of in the process of sewing, governor motion coordinate sense component groups and rolling structure both via electrically connect control module control signal, by adjusting cloth, push and make to carry out the flat state of cloth of sewing and keep seam order quality normal.

Background technology

In the sewing operation process of existing Sewing machines, sewing cloth often need be through repeatedly turnover, sewing cloth now because of and connect, the factor such as crease increases thickness, when this thicker sewing cloth is when pushing to pressure foot below, associated component cannot provide pressure to respond thicker sewing cloth, so carry out follow-up sewing, easily produce flaw or incomplete bouncing pilotage situation, cause sewing operation cannot reach consistent and stable quality.

Refer to shown in Fig. 4, it may be bilayer or multilayer that aforesaid cloth 94 increases thickness, its thickness is with the drop of individual layer can be to more than 2～4 times originally, and during normal sewing cloth 94, presser bar 9 can impose to press down or rise and make pressure foot 91 push down cloth 94 with suitable pressure, coordinate cloth conveying teeth part 93 to produce and push strength, the needlework 942 that stitch via suture needle 92 are with bottom line 943, because being subject to suitable pressure to be smooth and smooth and easy, cloth 94 pushes forward, therefore needlework 942 can be around forming correct seam order with bottom line 943; Refer to again shown in Fig. 5, when cloth 94 has convolution place 941, when sewing proceeds to this

convolution place

941,91 of pressure foots can produce unsettled situation with cloth 94 and occur, make needlework 942 and the bottom line 943 cannot be normally around forming correct seam order, and cause the get loose phenomenon of quality flaw of formation bouncing pilotage 944 of needle gage and bottom line 943 for several times; Therefore, how effectively improving cloth 94 and can form in the sewing operation between thick, thin the uniformity that correct seam order is reached quality, will be that the utility model wants actively to improve part.

Prior art

9 presser bar 41 convolution places

91 pressure foot 42 needlework

92 suture needle 43 bottom lines

93 cloth conveying teeth part 44 bouncing pilotages

94 clothes
