New description: [New technical field] This is a differential feeding device for a roller type feeding sewing machine, especially one that can produce an upper feeding wheel and a lower feeding wheel by an adjusting mechanism and a linkage mechanism. The relative speed change 'make the position of the sewing upper fabric and the lower fabric meet the desired requirements' while reducing the volume of the sewing machine body occupied by the interlocking mechanism, improving the convenience of the sewing machine, and achieving the practical purpose of the differential feeding device of the sewing machine. Recorded, and is distinguished by the differential feed device or similar structure of each fiber wheel type. [Prior Art] The control mechanism for the differential feed of the seam rush machine, which is combined with the clutch structure of the machine of the applicant of the Republic of China Xinmin Patent No. M335525, 'utilizes two sets of the clutch structure of the seam_ ,, the secret foundation, so that only the upper and lower feed rollers synchronously drive the feed _ machine structure is added to adjust the 2 synchronous speed increase and decrease; but because its structure is finely added to the outer space of the sewing machine body, assembly and adjustment need multiple The position of the step machine is larger than the position of the knob that originally adjusted the stitch length = improving the shortcomings and improving the convenience of operation. _forward-walking two: r-sewing-feeding stroke is divided into: before the needle feeding, before the r-feeding stroke, the needle is threaded through the fabric and the fabric is advanced at the same time. The upper and lower feeding wheels must be synchronized (the line speed is the same) , so that the upper = 3 M368662 fabric will not cause the pull hole or the needle to be bent due to the different feeding catch. 'The needle is tied to the tree and the return action is made. The upper and lower feeding wheels can be adjusted to be out of sync. It is used to control the individual feeding amount of the upper and lower layers of leather. The speed of the feeding wheel is the same as the feeding speed of the needle. The line speed of the wheel and the _ time is the treasury speed. When the Shangshan wheel turns faster than the synchronous speed, it is the secret of the silk. When the top wheel is slack, the differential speed is slow and the feed is reversed. The feeding device of the conventional roller type feeding rib machine has the principle of one-way pumping. The differential feeding device can be used for positive differential and reverse differential feeding, but needs to be adjusted by tools to change the swinging path of the swinging arm. 'Let's _ differential feeding function, so the reading system on the money is _. [New content] The main purpose of this creation is to provide a kind of slit _ differential feeding device 'by the down-selling body one on the mine, the _ _ structure and an adjustment mechanism of the age, scale _ structure hybrid Wei Between the lower secret mechanism and the upper feeding mechanism, for the linkage control of the lower riding touch the feeding mechanism 'and the age of the hitting machine (10) is connected, and by the link configuration and interaction relationship Through the clutch and _ power transmission, the wire speed of the sewing machine can be adjusted to increase the speed of the wire on the needle, and the transmission wire of the (10) casting can be placed in the same body of the sewing machine. Body _, the effect of the purpose of creating the differential feed device of the seam _, and the overall practicality and convenience. M368662 8 Ο, an upper feed clutch group 8 2, an upper transmission component group 8 3 and an upper feed wheel 25, the upper feed shaft 80 is coupled with the upper feed clutch group 8 2, and the upper The feed clutch group 8 2 controls the rotation of the upper feed wheel 25 via the upper transmission element group 8 3 , and an axial cam 821 is disposed on a side parallel to the upper feed clutch group 8 2 . A linkage mechanism 3 is coupled between the upper feeding mechanism and the lower feeding mechanism 2 for interlocking control of the upper feeding mechanism 1 and the downward feeding mechanism 2. An adjusting mechanism 4 is coupled to the linking mechanism 3. The adjusting mechanism 4 is provided with a latch 60, an adjusting arm 61, an adjusting screw 611, a tension spring 612, and a differential ratio adjustment. Button 613, a control link 6 2, an input link 3 6 , a joint pin 7 0 , a slotted swing arm 7 1 , a short rod set (A) 7 2, a short rod set (B) 7 3, a The control arm 74, a shaft 50, an output swing arm 51, a differential swing arm 52 and an output link 5 3 are pivoted and combined with the output swing arm 51 and the differential pendulum The upper end of the input rod 36 is simultaneously pivoted with the short rod group (A) 7 2 and the short rod group (B) 7 3 and moves to the inner side of the trough-shaped swing arm 7 1 , the differential swing arm 5 2 - a short pin 5 21 is arranged on each side of the end, and the other ends of the short rod group (A) 7 2 are respectively pivotally connected to the short pins 5 21 of the differential swing arm 5 2 - end, the trough pendulum The inner end of the arm 71 is provided with two opposite short pins 7 1 1 , and the other ends of the short rod group (B) 7 3 are respectively pivotally connected to the short pins 7 1 1 provided at the inner front end of the slot-shaped swing arm 7 1 . Short pin 7 1 1 forms short rod group (B) 6 M368662 Whole screw 611 is forced forward and belt The adjusting arm 6 i swings upward, and at the same time drives the _ link 6 2 pivotally connected to the adjusting arm 6 i - end, and the lower end of the paving rod 6 2 is pivotally connected to the control arm 7 4 , and the interlocking structural relationship makes the slot arm 7 i is deflected upward, the slotted swing arm 71 is turned to the angular position in the clockwise direction, and the angle between the input link 36 and the short rod set (8) 7 3 is far greater than 9 q degrees by the combination of the above various structural structures, The output stroke of the flail 5 3 is increased, and the right clutch 8 2 2 of the upper feed clutch group 8 2 is applied to the needle feed H _ to increase the feed amount of the upper weighing wheel on the needle feed stroke (positive silk secret); On the other hand, when #丝_调碰6丨3 rotates in the reverse direction, the adjustment screw 6 ! li4 shrinks and stretches the elastic yellow 6 work 2 back, under the force, the adjustment arm 6 1 is driven to swing downward, and its interlocking surface The system deflects the sharp fresh 7 1 downwards, and the position of the groove f 7 i _ counterclockwise (see Figure 6), at which point the input link 3 6 and the swivel (8) 7 3 angles approach 9 The twisting degree reduces the output stroke of the output link 53, and reduces the rotation angle of the right clutch 8 2 2 of the upper-feeder group 8 2 acting on the needle feeding stroke. That is, the feed amount of the upper feed wheel during the upper feeding stroke is reduced (inverse differential feed h is described above), and the power transmission and differential feeding of the clutch group are integrated in the sewing machine body by the structural configuration of the creation and the interaction relationship between the components. The function realizes the adjustment of the rotation speed of the upper feeding wheel on the feeding stroke, effectively reducing the volume occupied by the sewing machine body, improving the working efficiency of the sewing machine, achieving the purpose of creating the differential feeding device of the sewing machine, and increasing the overall practicability and convenience.
