Description

Technical Field

[0001] The utility model relates to the technical field of paper barrel hoop forming, in particular to an automatic forming device for a paper barrel hoop. Background Art

[0002] Paper drum ferrule is a ring or hoop structure fixed to the outer wall of the paper tube to achieve the purpose of strengthening the paper tube structure, improving the sealing performance or meeting specific packaging requirements. There are various types of paper drum ferrules, but in order to increase the durability of the paper tube, metal ferrules are usually used. During the production process of the ferrule, a forming device is usually used to press a strip of metal sheet into a ring structure, and then the two ends of the ferrule are welded together.

[0003] When the existing forming device is in use, when the two semicircular pressing blocks press the metal sheet into a ring structure, due to the close fit of the two semicircular pressing blocks, it is difficult for the welding equipment to weld the two ends of the ferrule. It is necessary to use a clamp to contact the two ends of the ferrule later, and then use a welding device separately to weld the two ends of the ferrule together. This will increase the production process and reduce the production efficiency of the ferrule. Utility Model Content

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figure 1-4In one embodiment of the present invention, an automatic forming device for a paper barrel sleeve comprises a frame 1, a cylindrical block 2, two symmetrical extrusion mechanisms 3, a welding mechanism 4, a limiting mechanism 5, and an adjustment mechanism 6. The frame 1 is fixed to the ground by bolts. An operating panel 11 is fixedly connected to the interior of the frame 1. A sliding hole 12 is formed through one side of the operating panel 11 and is located above the center of the cylindrical block 2. The cylindrical block 2 is detachably connected to one side of the operating panel 11 by bolts. Two symmetrical extrusion mechanisms 3 are provided on one side of the operating panel 11, located above and below the cylindrical block 2. The welding mechanism 4 is fixedly connected to one side of the operating panel 11 and located above the cylindrical block 2. The limiting mechanism 5 is provided on the operating panel 11 and is used to squeeze the ends of the half-formed web toward the center. The limiting mechanism 5 includes two symmetrical abutment plates 51 that are slidably connected within the sliding hole 12. The adjustment mechanism 6 is provided on one side of the operating panel 11 and is used to vertically align the center of the web with the center of the cylindrical block 2.

[0038] Specifically, first place the cut tape under the cylindrical block 2, then start the extrusion mechanism 3 under the cylindrical block 2 to form a U-shaped tape structure, and by the two abutment plates 51 approaching each other, the two ends of the U-shaped tape can be brought closer to the middle, and then the U-shaped tape is pressed into an annular structure by driving the upper extrusion mechanism 3. By restoring the upper extrusion mechanism 3 to its original position, the two abutment plates 51 are now against the outer wall of the annular tape and located above the center of the annular tape, so that the two ends of the annular tape can be stuck together, and then the welding mechanism is used. 4 The two ends of the annular tape are welded together. By restoring the lower extrusion mechanism 3 to their original positions and the two abutment plates 51 to their original positions, the annular tape on the cylindrical block 2 can be removed. The device first brings the two abutment plates 51 closer together to bring the two ends of the U-shaped tape closer together, making it easier for the upper extrusion mechanism 3 to press the U-shaped tape into an annular tape. Then, the two abutment plates 51 are used to stick the two ends of the annular tape together, making it easier for the welding mechanism 4 to weld the annular tape. Therefore, no additional production process is required, which can improve the production efficiency of the ferrule.

[0039] Example 1

[0040] like Figure 3As shown, in this embodiment, one end of the push plate 51 located on the back of the operating panel 11 is fixedly connected to a connecting block 52, and the two connecting blocks 52 are provided with telescopic parts on the side opposite to each other. The two telescopic parts are fixedly connected to a connecting plate 55 on the side opposite to each other, and a double-headed cylinder 56 is fixedly connected between the two connecting plates 55. The back of the operating panel 11 is fixedly connected to a fixing seat fixedly connected to the double-headed cylinder 56. The telescopic part includes a sleeve 53 fixedly connected to one side of the connecting plate 55 at the corresponding position, and a sleeve rod 54 is slidably sleeved in the sleeve 53 at the corresponding position and fixedly connected to the connecting block 52 at the corresponding position. A spring 1 is fixedly connected between the sleeve 53 and the sleeve rod 54 at the corresponding position. The top surface of the push plate 51 is fixedly connected to an inclined plate 57. The outer side of the push plate 51 located on the front of the operating panel 11 is fixedly connected to a limit sleeve 58 that abuts against the operating panel 11. The front of the operating panel 11 and below the cylindrical block 2 are fixedly connected to two symmetrical supporting plates 13.

[0041] When the upper extrusion mechanism 3 moves downward, the two anti-plates 51 are in contact with the outer wall of the strip under the action of the spring 1 at the corresponding position, and the downward movement of the upper extrusion mechanism 3 contacts the inclined plate 57, which can make the anti-plate 51 at the corresponding position move in the opposite direction and compress the spring 1 at the corresponding position. When the upper extrusion mechanism 3 presses the U-shaped strip into an annular strip, the upper extrusion mechanism 3 returns to its original position and disengages from the two anti-plates 51. At this time, the compressed spring 1 is released, so that the two anti-plates 51 contact the outer wall of the strip again. If the two anti-plates 51 cannot stick the two ends of the annular strip together, the double-headed cylinder 56 can be started again until the two anti-plates 51 can stick the two ends of the annular strip together, and then the two ends of the annular strip are welded together by the welding mechanism 4.

[0042] Example 2

[0043] like Figure 4 As shown, in this embodiment, a scale 14 is engraved on the front of the operating panel 11, and a fixed block 15 is fixedly connected to one side of the front of the operating panel 11. The adjustment mechanism 6 includes a screw 61 that passes through and is screwed on the side of the fixed block 15, a contact plate 62 that is rotatably connected to one end of the screw 61 and abuts against the operating panel 11, a rotating block 63 is fixedly connected to the other end of the screw 61, and a spring 2 64 is fixedly connected between the fixed block 15 and the contact plate 62.

[0044] In this embodiment, the cut tape is placed on two supporting plates 13 with one end of the tape in contact with the contact plate 62, and then the screw 61 is rotated by rotating the rotating block 63. Since the screw 61 is screwed through and engaged with the fixed block 15, the rotation of the screw 61 can move the contact plate 62, thereby moving the tape until the contact plate 62 reaches the appropriate position on the scale 14, at which time the center of the tape is vertically aligned with the center of the cylindrical block 2 (for example, if a hoop with a circumference of 20CM is required, a tape with a length of 20cm is placed on the two supporting plates 13 with one end of the tape in contact with the contact plate 62, as shown in FIG. Figure 2 As shown, the starting position of the scale 14 is at the center of the cylindrical block 2, so it is only necessary to move the contact plate 62 to the position of the imprint 10 cm, at which time the center of the 20 cm long tape is vertically aligned with the center of the cylindrical block 2), and then the tape is pressed into a ring structure by successively starting the two extrusion mechanisms 3.

[0045] Example 3

[0046] like Figure 2 As shown, in this embodiment, the top and bottom ends of the front side of the operating panel 11 are fixedly connected to the fixed plate 16, and the extrusion mechanism 3 includes two symmetrical hydraulic cylinders 31, a mounting plate 32, and an extrusion block 33. The two symmetrical hydraulic cylinders 31 are fixedly connected to the fixed plate 16 at corresponding positions, the mounting plate 32 is fixedly connected to the output ends of the two hydraulic cylinders 31 at corresponding positions, and the extrusion block 33 is fixedly connected to the mounting plate 32 at corresponding positions by bolts.

[0047] In this embodiment, the cylindrical block 2 and the two extrusion blocks 33 are detachably connected, so that the sizes of the cylindrical block 2 and the two extrusion blocks 33 can be easily replaced according to the size of the ferrule to be produced.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
