The feeding member 57 is connected to the first driving rod portion 521 of the driving rod 52 by a link transmission mechanism (not shown). The top surface of the feeding member 57 is provided with a plurality of protruding teeth 571 ' for abutting against the cloth 20 In order to drive the fabric 2〇 forward. As shown in FIG. 4 and FIG. 5, the first driving rod portion 521 of the driving rod 52 can be driven by the eccentric shaft portion with the first pivot point 523 as an axis center relative to the substrate 51 at a first swing position (as shown in FIG. 4) moving between a second swing position (such as FIG. 5), when the first drive rod portion 521 is in the first swing position, the second drive rod portion 522 is horizontally adjacent to the front side wall of the casing 22, and The pivot axis 533 of the first link 53 is located at a lowest position in the guide groove 511 of the substrate 51, and the fourth pivot point 535 of the second rod portion 532 is at a point of a point. At this time, the striker 44 of the actuating unit 4 is at A far away from the ultrasonic vibration head 31 and the highest limit position of the cloth 2〇11 M3 00217. When the first driving lever portion 521 is rotated in the needle direction, the second driving lever region is driven: 523: the axial center advances toward the rearward direction, and simultaneously drives the first continuous drying, 2 rotates in a horizontal direction toward the hour hand, and The first pivoting shaft 533 moves downward toward the counter-rotating rod 54 and the second connecting rod 54: the second stem portion 532 pushes the second coupling 42 downward. Until the first driving portion 521:=Γ simultaneously drives the fourth pivot point 53 of the second rod portion 532 of the cylinder to move the position of the first pivoting position, and the striker 44 of the element 4 is at the position of the _ and the Β, The lowest limit position for the action order. _ movement between the abutting ultrasonic vibration horn 31 and the moving position: the moving rod portion 521 moves between the first and second swings, and drives the first continuous drag to make the striker 44 as a point. What is the fabric between the positions? The η I & ultrasonic ultrasonic welding head 31 heats the fabric 20 and matches the striker 4: the effect of the shell is melted. Therefore, the fabric of (4) is produced. 2: When the joint is: When the cylinder 42 is moved up and down, the first: 43 is simultaneously changed between the compressed state and the stretched state, by the sister-flat component. The elastic restoring force of 43 can be increased by the force of the squeezing of the squeezing material. The force can be adjusted by the (four) force adjusting cylinder 41 to the inner casing U. Furnace, on the other hand 'because of the first drive of the feed element 57 and the drive rod 52: two 521: connection' so when the first drive rod portion 521 is moved from the first swing position to the first swing position, the feed element 57 will be - the position of the younger one that is aligned with the top surface of the working platform 21 is moved downward by a vertical distance and then moved forward - the horizontal distance to a second position lower than the top surface of the working platform 21, when the first - 12 M300217 tilts the cup portion 521 When the second swinging element 57 is moved from the second motion to the younger-swing position, the vertical distance is moved upward and then to the first position, by the first driving rod portion. 52丨 reciprocating between the swinging positions, the feeding element ^ will move in the same direction between the two forwards to drive the fabric 2〇 gradually toward the rear two slits: the user can operate the fabric... As shown in Fig. 6 and As shown by 'manually or otherwise, the brake element is brought into position by the horizontal position in the counterclockwise direction to the abutment with the engaging member W." The fourth pivot point of the connecting rod 53 is at the point A. Will be braked at the highest limit and cannot move down to avoid When the impact ultrasonic vibration is on the working platform 21, the striker 44 is heavy and the boring head 31 is worn, causing wear and damage. This is still caused by the eccentric shaft portion of the 2-1th driving member 52 1 The four pivot point 17 is continuously reciprocated between the positions, and the 521 of the first link 53 is restricted to the position A, so that the second drive lever portion 522 is when the first drive lever is in the machine position. The side wall of the first link 53 is located at a lowest position in the substrate/the groove 511. The shifting second tilting lever portion 521 is moved from the first swing position to the second swing position. When moving, when a hit and a catch 53 will rotate with the fourth pivot point 535 as the axis relative to the first turn, the pivot axis 533 5曰21 of the first link 53 will be The lowest position in the slot...5U slides upward until the first drive lever portion reaches the second swing position, and the second drive lever portion 522 abuts against the 13 M3 00217-one drive lever portion 521 in an inclined manner. The pivoting shaft 533 is located at the highest position in the slot 11. Since the first driving lever portion 521 is not subject to the brake element% The pivoting shaft 533, which continues to be in the first and second swing positions, drives the pivot link 533 of the first link 53 to reciprocate up and down between the lowest position and the most squat position in the guide groove 5 ι. - The work cloth is placed in the work translation welding The head 31 causes wear and thereby, and the situation in which the striker 44 strikes the ultrasonic shock when the user is not attached to the table 21 can be avoided.

The swing position. Thereby, the first drive lever 521 is moved between the first and second swing positions (four), and the fourth pivot point 535 of the first link 53 is at the point a (the figure 8 has been marked with the point c) Moving between and the pivot axis 533 of the first link 53 is moved between the lowest position and the D point position in the guide groove to complete the up and down reciprocation of the striker 44. Thereby, when the thick thickness of the cloth 23 is welded The striker 44 can automatically change the displacement between the last limit position and the lowest limit position and the force of depression. 14 M3 00217 In addition, when the thick and thin fabric is attached, the position of the striker will change with the low limit of the fabric and the lower limit of the lower limit, so that the pivot point 535 of the first link 53 is moved to, 丨I door J music moves to different position points in four seconds, so that the first coupling shaft 533 can take the 柩 turning point of the disc cylinder-dry j as the axis at the position, and moves to one in the guiding groove 511, so that the first The pivot shaft 533 of the connecting rod 53 can correspond to the cloth: the t-slot 5U is called the lowest position, and the position of the corresponding point of the money slips, and the reciprocating motion of the 1 striker 44 is 70, the most ήa, and the corresponding point can be moved to the most The same position is the highest position of the pivot shaft 533 as shown in Fig. 7. When the ultrasonic slit _ 2 (9) is running, the thick needle of the cloth can be automatically generated by the striker 44 of the actuating unit 4 The second method is suitable for fusion of thick and thin faults on the fabric. In summary, the welding device of the ultrasonic slitting machine of the present embodiment, the arrangement of the moving unit 5 and the actuating unit 4 is such that the striker 44 can follow the thickness of the object; Automatically change the displacement between the highest limit position and the lowest limit position to fit on the fabric There is a fusion of thick and thin faults, so it is the purpose of the present invention. 1 This is only the preferred embodiment of the present invention, and the scope of the present invention is limited to the scope of the present invention.
