The wind-up roller 22 is located on the front side of the guide roller assembly 21, and is slightly higher (located lower) than the first guide roller 211. The cooperation of the guide roller assembly 21 and the edge rollers 22 guides the leading end of the skirt blank to bend upwardly to form the annular skirt 100. The feed roller assembly 23 and the guide roller assembly 21 may be rotated by a second drive motor (not shown) via a sprocket chain assembly.

When skirtboards with different specifications need to be processed, an operator can directly connect the limit stop lever 32 to different connecting positions 3100, for example, when a skirtboard blank with a relatively large size needs to be processed, the limit stop lever 32 can be mounted on the corresponding connecting position 3100 close to the front (the position is also relatively high) of the limit bracket 31; when it is desired to machine apron blanks of relatively small dimensions, the limit stop 32 can be mounted on a corresponding rearward (also relatively lower) attachment site 3100 of the limit bracket 31.

The above-mentioned turnover driving member 33 can adopt various existing technologies such as air cylinder, electric push rod, etc., and the turnover driving member 33 in this embodiment is preferably an air cylinder, which is substantially vertically disposed and the bottom of which is hinged on the frame 1.

The positioning rod 44, the positioning post 46, and the tension spring 47 together constitute the lock mechanism of the present embodiment.

The design of the locking mechanism also facilitates the operator to correspondingly adjust the skirtboards of different specifications, for example, when the large-size skirtboard workpiece needs to be subjected to edge rolling welding processing, the operator can lift the positioning rod 44 to separate the positioning notch 440 from the positioning column 46 on the rack 1, then move the limiting baffle plate 41 backwards, after the positioning rod is moved in place, under the elastic action of the tension spring 47, the positioning rod 44 automatically swings downwards, and the positioning notch 440 at the corresponding position on the positioning rod is clamped with the positioning column 46 and cannot be easily separated.

On the other hand, the edge rolling processing and the welding processing of the apron board blank are centralized on the same position, so that the volume of the whole equipment can be effectively reduced, and the occupied space is reduced.

With reference to fig. 3 and 4, in order to firmly press the front and rear ends of the annular skirt board 100 after being aligned, the first pressing assembly and the second pressing assembly are arranged at an interval in the horizontal direction (i.e., the front and rear direction of the rack 1), wherein the first pressing assembly and the second pressing assembly are located at the end position of the annular skirt board 100, and may be specifically disposed on the second vertical plate 96.

After the adjustment process of the lifting assembly, the rear end of the annular skirt 100 slightly moves upward to be displaced between the welding socket 12 and the welding platform 11, and then the vibrator 72 of the skirt vibration pressing mechanism acts on the top of the annular skirt 100 to move the rear end of the annular skirt 100 toward the front end of the annular skirt 100 to be aligned with the front end of the annular skirt 100, at this time, the second pressing assembly is actuated to make the second pressing arm 66 thereof press the rear end of the annular skirt 100 against another stop of the rack 1 along the axial direction thereof.
