[0025] In this embodiment, a casing clamping mechanism of a sealing machine is disclosed, which includes an outer sleeve 1, an inner sleeve 10 coaxially inserted into the outer sleeve 1, a deflection mechanism for adjusting the relative rotation of the inner sleeve 10 with respect to the outer sleeve 1, and a lead screw mechanism for adjusting the synchronous expansion and contraction of the outer sleeve 1 and the inner sleeve 10.

[0026] In this embodiment, as shown in Figure 1 and Figure 2As shown, the screw mechanism includes a first screw support plate 201, a second screw support plate 202, two sliding bearing guide rods 4 connecting the first screw support plate 201 and the second screw support plate 202, screws 2 respectively mounted on the first screw support plate 201 and the second screw support plate 202 through bearings, and a screw motor 3 driving the screw 2 to rotate. The first screw support plate 201 is mounted on the frame through the rear mounting flange 102, and the second screw support plate 202 is mounted on the frame through the front mounting flange 101; the two ends of the outer sleeve 1 respectively penetrate the front mounting flange 101 and the rear mounting flange 102; a ball screw seat 203 is fixed on the outer wall of the outer sleeve 1, a screw nut adapted to the screw 2 is mounted on the ball screw seat 203, and the sliding bearing guide rod 4 is also mounted on the ball screw seat 203 through a straight bearing. A belt drive pulley is installed at the shaft end of the screw 2, the screw motor 3 is installed on the frame, and a pulley is installed at the power output end of the screw motor 3, and is connected to the belt drive pulley at the shaft end of the screw 2 through a belt 301.

[0027] When working, the screw motor 3 is started, and the screw 2 is driven to rotate through the belt 301, thereby driving the ball screw seat 203 installed on the screw 2 to move relative to the first screw support plate 201 and the second screw support plate 202 at both ends of the screw 2, thereby adjusting the displacement of the outer sleeve 1 relative to the front mounting flange 101 and the rear mounting flange 102. Figure 3 As shown, since the inner sleeve 10 is limitedly connected to the outer sleeve 1 through the rotating bracket 503, the screw mechanism can be used to adjust the synchronous telescopic action of the outer sleeve 1 and the inner sleeve 10.

[0028] In this embodiment, Figure 5 and Figure 6 As shown, the adjusting necking member 9 is an arc-shaped plate, and a stepped structure with a drop is designed in the middle of the arc-shaped plate, wherein one end of the adjusting necking member 9 is provided with a limiting long hole 902 which is limitedly connected to the inner ring 8, and the other end thereof is provided with a hinge hole 901 which is hingedly connected to the outer ring 7.

[0029] In this embodiment, Figure 2 and Figure 3 As shown, a reserved arc groove 103 is provided on the side wall of the outer sleeve 1, and a rotating bracket 503 extending out of the reserved arc groove 103 is fixed on the inner sleeve 10; wherein the rotating bracket 503 is deflected and adjusted in the reserved arc groove 103 by the deflection mechanism; wherein the deflection mechanism includes a pull rod 502 transmission-connected to the rotating bracket 503, and a deflection motor 5 driving the pull rod 502 to deflect.

[0030] In this embodiment, Figure 2 and Figure 3 As shown, a rotating pin 501 is installed on the power output shaft of the deflection motor 5, and one end of the pull rod 502 is hingedly connected to the rotating pin 501. A clamping bracket 601 is rotatably installed on the front mounting flange 101 and the rear mounting flange 102 respectively; two rotating bracket guide rods 6 are installed between the two clamping brackets 601; one of the rotating bracket guide rods 6 is hingedly connected to the other end of the pull rod 502, and the other rotating bracket guide rod 6 is hingedly connected to the rotating bracket 503.

[0031] During operation, the deflection motor 5 drives the rotating pin 501 to rotate, thereby driving the pull rod 502 to deflect, and then driving the clamping bracket 601 to deflect relative to the front mounting flange 101 and the rear mounting flange 102, thereby driving the rotating bracket 503 to rotate, and finally driving the inner sleeve 10 to rotate relative to the outer sleeve 1, thereby cooperating with the adjusting necking piece 9 installed at the end of the inner sleeve 10 to adjust the necking.

[0032] like Figure 5 As shown, an outer ring 7 is installed at the end of the outer sleeve 1, and an inner ring 8 is installed at the end of the inner sleeve 10; wherein three adjusting shrinking parts 9 are transmission-connected between the outer ring 7 and the inner ring 8.

A plurality of hinge holes 701 adapted to the hinge holes 901 are installed at even angle intervals on the outer ring 7.

[0033] During operation, the deflection motor 5 in the deflection mechanism is driven by transmission to drive the inner sleeve 10 to rotate relative to the outer sleeve 1, thereby driving the inner ring 8 to rotate relative to the outer ring 7; since the limiting long hole 902 at one end of the adjusting necking piece 9 is adapted and plugged with the column pin 802 on the inner ring 8, the hinge hole 901 at the other end of the adjusting necking piece 9 is hingedly connected with the hinge hole 701 on the outer ring 7 through a pin shaft;

[0034] When the inner ring 8 drives one end of the adjusting necking piece 9 to deflect, since one end of the adjusting necking piece 9 is relatively fixed, it is convenient to adjust the three adjusting necking pieces 9 to shrink or diverge relative to each other through the deflection mechanism, so as to achieve the purpose of shrinking; in this embodiment, the adjusting necking piece 9 is an arc-shaped plate, and the middle part of the arc-shaped plate is designed as a stepped structure with a drop, so that when adjacent adjusting necking pieces 9 shrink, a gap is reserved for overlapping.
