Referring to fig. 7-11, further, as another preferred embodiment of the elastic top member 42, the arc plate 422 is replaced by a disk-shaped disk, the top member further comprises a disk-shaped disk 425, a plurality of disk-shaped disks 425 are oppositely arranged at the mouth part, oppositely arranged at the bottom part and serially arranged on the core rod 421, the inner arc surface of the disk-shaped disk 425 at the inner end part is arranged towards the tank 50, the edge of the mouth part is used for contacting with the tank 50, and the outer arc surface of the disk-shaped disk 425 at the outer side is arranged towards the fastening nut 423, so that the fastening nut 423 contacts with the outer arc surface of the disk-shaped disk 425. The metal disc of this scheme adoption dish type replaces arc 422, because arc 422 need adjust the edge just to the position when contacting each other, and area of contact is limited, and the position is difficult to master for alignment is aimed at the cost time longer before the top is tight, and the operation is complicated, and dish type dish mouth portion is circular, need not the alignment and aims at, and two adjacent dish shape dishes 425 can be adjusted well to the top is tight simultaneously, and area of contact is big, comparatively stable.

Further, the mouth calibers of the disc-shaped discs 425 are not equal. When the disc-shaped discs 425 with the same caliber are adopted, when two adjacent disc-shaped discs 425 are contacted, the relative contact of the mouth parts can only be ensured, the area of the mouth parts is small, the deformation exists after the disc-shaped discs 425 are used for many times, the two disc-shaped discs can not be just in full contact, and the radial force is transmitted, so the problems of unstable contact, serious deformation or unstable jacking force exist, the disc-shaped discs 425 with different calibers are adopted in the scheme, when the adjacent disc-shaped discs 425 are contacted, the disc-shaped discs 425 with smaller calibers are contacted with the inner arc-shaped surfaces of the disc-shaped discs 425 with larger calibers, so that all the disc-shaped discs 425 with smaller calibers are in full contact with the disc-shaped discs 425 with larger calibers, the contact is stable, the influence caused by the deformation is avoided, and the inner arc-shaped surfaces of the disc 425 with larger calibers wrap the mouth parts of the disc-shaped discs 425.

Further, the caliber of the smaller caliber disk 425 is between 1/4-1/3 of the caliber of the larger caliber disk 425.

Furthermore, a concentric and coaxial outer steel ring 43 is arranged outside the inner steel ring 41, the outer steel ring 43 is fixedly connected with the inner steel ring 41, and the end part of the core rod 421 penetrates through the inner steel ring 41 to be fixed on the inner wall of the outer steel ring 43. The reaction force of the inner steel ring 41 bearing the jacking piece can be transmitted to the outer steel ring 43, the strength of the inner steel ring and the outer steel ring is reinforced under the combined action of the inner steel ring and the outer steel ring, the fixing effect of the core rod 421 is realized by the outer steel ring 43, the inner steel ring 41 forms the limiting and positioning effect on the core rod 421, the stress on the end part of the core rod 421 is distributed, the radial acting force of the stress is borne by the inner steel ring 41, and the radial fixing force is borne by the outer steel ring 43, so that the jacking piece is more stable and reasonable in structure, and the service life of the jacking piece is longer.

Further, since the space between the lower part of the rolling device and the main support 11 is suspended, a support wall 111 is further disposed in the middle of the main support 11, support rollers 112 are disposed above the support wall 111, and bearings are disposed between the two ends of the support rollers 112 and the wall body, so that the support rollers 112 and the support wall 111 roll relatively. Since the shaking device is used as a driving member, the intensity and the supporting capability thereof are limited, and the upper structure thereof also bears the gravity of the tank 50, so the bearing force is also large, in order to enhance the stability thereof, a supporting wall 111 is arranged for bearing the upper gravity, and simultaneously, a supporting roller 112 and a bearing are arranged in order to ensure that the mutual friction force, the resistance and the noise are small when the rolling device rotates.

Further, the flame projecting device 20 includes a plurality of bottom flame projecting heads, two sets of tip flame projecting heads, and the bottom flame projecting head is located the main support 11 below, and sets up for just to the jar body 50 of top, and two sets of tip flame projecting heads set up both ends around the main support 11 respectively, and set up relatively, are used for just to two tip of the jar body 50 in the middle.

The embodiment of the utility model provides a module or unit in the device can merge, divide and delete according to actual need.
