The conveying belt locking mechanism 2-3-8 is provided with a fastener, and the fastener is screwed to press the conveying belt pressing guide wheel 2-3-7, so as to press the conveying belt 2-3-6-1 by the pressing wheel.

[0070] The rolling equipment of the embodiment can adjust the locking degree of the conveying belt locking mechanism 2-3-8 to the conveying belt 2-3-6-1 by adjusting the fastener. For example, the conveying belt pressing guide wheel 2-3-7 and the conveying belt locking mechanism 2-3-8 can be arranged at the right angle of the outer pressing component rack 2-3-1 in the shape of a right-angled triangle. The fastener can be a screw, and the pressure applied by the fastener to the conveying belt pressing guide wheel 2-3-7 can be adjusted by adjusting the screwing degree of the fastener. The conveying belt locking mechanism 2-3-8 can be fixed to the outer pressing component rack 2-3-1 through a screw.

[0077] As shown in Figure 14 , according to one embodiment of the utility model, the inner supporting base 1-1 is provided with an inner supporting base guide rail 1-3, and the inner support 1-5 is movable along the inner supporting base guide rail 1-3 to approach or move away from the weld joint.

[0078] In the embodiment, the setting stroke direction of the inner supporting base guide rail 1-3 is the radial direction of the melon petal or the head. The inner supporting base guide rail 1-3 can provide guidance and limiting for the inner support 1-5.

[0079] According to one embodiment of the utility model, the inner supporting base 1-1 is provided with a limiting driving cylinder 1-2. The inner support 1-5 is provided with a limiting block 1-4 corresponding to the limiting driving cylinder 1-2. When the inner support 1-5 moves to the rolling position, the limiting driving cylinder 1-2 is extended to limit the inner support 1-5 through the limiting block 1-4.

[0080] In the embodiment, the inner support base guide rail 1-3 can be provided with a rectangular hole on the side facing the limiting driving cylinder 1-2, and the inner support 1-5 can be provided with a limiting block 1-4 on the side facing the rectangular hole, and the limiting block 1-4 can extend out of the rectangular hole. The limiting driving cylinder 1-2 can be a pneumatic cylinder. The limiting block 1-4 can be L-shaped. The limiting driving cylinder 1-2 can include a telescopic cylinder and a (circular arc-shaped) limiting rod. When the inner support 1-5 reaches the rolling position, the telescopic cylinder is elongated to push the limiting rod to extend out, block the limiting block 1-4, and prevent the inner support 1-5 from moving during the entire rolling process.

[0081] As shown in Figure 15 , the inner support base 1-1 is provided with a linear gear guide rail 1-7, and the inner support 1-5 is provided with a gear 1-9 engaged with the linear gear guide rail 1-7. The gear 1-9 moves along the linear gear guide rail 1-7 to drive the inner support 1-5 to move along the inner support base guide rail 1-3.

[0082] In the embodiment, the linear gear guide rail 1-7 is parallel to the inner support base guide rail 1-3. The gear 1-9 can be installed on the rotating shaft of a gear driving motor 1-8 to be driven by the gear driving motor 1-8. The linear gear guide rail 1-7, the gear driving motor 1-8, and the gear 1-9 cooperate to realize the linear motion of the inner support 1-5 relative to the inner support base guide rail 1-3.

[0083] As shown in Figure 2 , 14 and 16, according to an embodiment of the utility model, the outer pressure component rack 2-3-1 is provided with a vertical locking mechanism 2-3-12 near the top end of the storage box, and the top end of the inner support 1-5 is provided with a lock catch 1-6 matched with the vertical locking mechanism 2-3-12. The vertical locking mechanism 2-3-12 includes a ring-shaped rotating rod 2-3-12-3 and a rotating driving machine 2-3-12-2. The rotating driving machine 2-3-12-2 is started to drive the ring-shaped rotating rod 2-3-12-3 to rotate, so that the ring-shaped rotating rod 2-3-12-3 is locked or unlocked with the lock catch 1-6, and the outer pressure component rack 2-3-1 is locked or unlocked with the inner support 1-5.

[0084] In the embodiment, when the longitudinal seam of the short cylinder or the head petal is rolled, the rolling mechanism rack 2-3-4-6 is locked with the inner support 1-5 through the ring-shaped rotating rod 2-3-12-3 and the lock catch 1-6, which ensures the rolling effect of the rolling mechanism.

[0085] For example, the rotary drive machine 2-3-12-2 can be an electric motor. The rotary drive machine 2-3-12-2 can be rotatably connected to the outer pressing component frame 2-3-1 through a rotary motor base 2-3-12-1. The locking buckle 1-6 can be arranged on the top of the non-rolling surface (i.e., the vertical surface) of the inner support 1-5. The annular rotary rod 2-3-12-3 can be an annular rod with an opening, one end of the opening being connected to the rotating shaft of the rotary drive machine 2-3-12-2, and the other end being rotatably connected to the other side (e.g., the right side cover plate 2-3-10) of the outer pressing component frame 2-3-1 through the rotary motor base 2-3-12-1 and the one side (e.g., the left side cover plate 2-3-9) of the outer pressing component frame 2-3-1. When the rotary motor base 2-3-12-1 is started, the rotating shaft of the rotary motor base 2-3-12-1 rotates, driving the annular rotary rod 2-3-12-3 to rotate relative to the outer pressing component frame 2-3-1, so as to approach or move away from the locking buckle 1-6 to lock or unlock the locking buckle 1-6.

[0086] As shown in FIGS. Figure 4 , 17 and 18, according to one embodiment of the present application, the rolling equipment further comprises a top cover column 3 arranged in the middle of the head. The outer pressing component frame 2-3-1 is arranged with a horizontal locking mechanism 2-3-11 near the top end of the head. The horizontal locking mechanism 2-3-11 comprises a horizontal locking motor 2-3-11-1 and a locking rod 2-3-11-2, and the locking rod 2-3-11-2 is rotatably connected to the outer pressing component frame 2-3-1 through the horizontal locking motor 2-3-11-1. When the horizontal locking motor 2-3-11-1 is started, the locking rod 2-3-11-2 is driven to rotate horizontally to approach or move away from the top cover column 3, so as to lock or unlock the locking rod 2-3-11-2 and the top cover column 3, and lock or unlock the outer pressing component frame 2-3-1 and the top cover column 3.

[0087] In the present embodiment, for example, the top cover column 3 can be arranged with a groove corresponding to the locking rod 2-3-11-2, so as to clamp the locking rod 2-3-11-2.

[0088] The above embodiments of the present application can be combined with each other, and have corresponding technical effects.

[0089] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
