Description

Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly of a flip wheel, in particular to a disassembly and assembly kit of a flip wheel. Background Art

[0002] The ZJ118 cigarette making unit is a medium-speed feeding and forming unit with advanced technology produced by Changde Cigarette Machinery Co., Ltd. The function of the YJ26MAX flip wheel of the ZJ118 cigarette making unit is to turn the ignition end or the mouthpiece end of the inner and outer exhaust cigarettes conveyed by the ZJ118 cigarette machine MAX transfer drum into inconsistent directions. Through the flipping of the drum wheel, the filter cigarettes with two rows of filter tips facing each other are turned into the same filter tip ends and arranged in a row and passed to the next drum wheel. Therefore, the cigarette flip wheel device is set on the receiving machine. The device usually adopts two structural devices in the design of the machine model, one is the 90E flip wheel (rotating hand flip wheel) and the other is the conical flip wheel device.

[0003] The conventional disassembly of the existing ZJ118 flip wheel is completely carried out manually, without special tooling, and requires more than two people to knock or even pry and tie with ropes to disassemble and install. The disassembly and installation of the YJ26 MAX turning wheel of this unit is extremely inconvenient. The drum wheel weighs more than 80 kilograms and is large in size. It requires more than two people to disassemble or install it. The function of the ZJ118 YJ26MAX flip wheel is to turn the ignition end or the mouthpiece end of the inner and outer exhaust cigarettes conveyed by the ZJ118 cigarette machine MAX transfer drum part into inconsistent directions. Through the flipping of the drum wheel, the filter cigarettes with two rows of filters facing each other are turned into the same filter end and arranged in a row and passed to the next drum wheel. Therefore, the cigarette flip wheel device is set on the receiving machine, and the device is equipped with a cylindrical cam mechanism and a disc cam mechanism. The cylindrical cam mechanism controls the movement of the rotating hand, and the disc cam mechanism controls the movement of the telescopic hand. During the operation, disassembly and installation of the drum, the telescopic hand will close and retract as the drum rotates. Since there is no effective safety support force point, the maintenance personnel may be pinched if they are not careful.

[0004] The flip wheel is mainly composed of a cylindrical cam mechanism 11 and a disc cam mechanism (the disc cam mechanism is protected by an end protection cover 14, and the outer shaft protection cover 15 is connected to the end protection cover 14 by bolts to protect the outer shaft of the flip wheel). The disc cam controls the telescopic hand 12 to receive a filter cigarette, and at the same time, the cylindrical cam controls the rotating hand 13 to receive another filter cigarette. When the cigarette turns to the intersection of the flip wheel and the detection drum, the disc cam has extended the telescopic hand 12 to accurately send the filter cigarette to the cigarette receiving groove of the detection drum. At this time, the cylindrical cam has rotated the rotating hand 13 180° and is one slot away from the telescopic hand, sending the other filter cigarette to another cigarette receiving groove of the detection drum. In this way, the filter cigarettes transferred from the transmission drum wheel are changed from double rows to single rows after passing through the flip drum, and the filter tips are in the same direction.

[0005] The structure of the flip wheel is relatively complicated. When the whole is disassembled and assembled, the telescopic hand 12 will close and retract with the rotation of the drum wheel. Since there is no effective safety support force point, the maintenance personnel may be pinched if they are not careful. In addition, during the separation process of the disc cam and the cylindrical cam mechanism, since the top force of the compression spring is very strong and the friction between the disc cam and the outer shaft is very small when they are about to separate, the compression spring has a large elastic impact force, which may push the disc cam out of the drum wheel and injure the maintenance personnel.

[0006] Based on this, it is necessary to design a targeted disassembly and installation tool to solve the problems of difficult disassembly and installation and easy injury to maintenance personnel during the disassembly and installation of the flip wheel. Utility Model Content

[0007] In view of the above problems, the utility model provides a flip wheel disassembly and assembly kit to facilitate the removal and installation of the flip wheel from or onto the equipment, as well as the disassembly and assembly of the disc cam mechanism, which is beneficial to improving the disassembly and assembly efficiency of the flip wheel and the safety during the disassembly and assembly process.

[0013] The disc cam mechanism disassembly and assembly tool comprises:

[0016] The nut is threadably connected to the screw rod and is located at a side of the pressing block away from the disc cam mechanism.

[0017] Furthermore, a hexagonal structure is provided at one end of the screw rod away from the disc cam mechanism.

[0018] Furthermore, a clamping assembly is provided on one side of the pressing block close to the hexagonal structure, and the clamping assembly is matched with the hexagonal structure and is used to rotate the screw.

[0019] Furthermore, the clamping assembly comprises: two symmetrically arranged clamping bodies, both of which are hinged to the pressing block, and the two clamping bodies clamp the hexagonal structure when closed.

[0020] Furthermore, a handle is provided on the clamping body.

[0021] Furthermore, the clamping block is fixedly connected to the nut, and the clamping block is threadedly connected to the screw rod.

[0023] Furthermore, a sink is provided in the middle of the connection part, and a plurality of mounting holes matching with the screw holes of the end protection cover are provided on the connection part, and the bolts are connected with the screw holes after passing through the mounting holes.

[0024] The working principle of this utility model:

[0025] Separation of the flip wheel from the equipment: first remove the outer shaft protective cover 15 at the outermost end of the flip wheel (the outer shaft protective cover 15 is connected to the end protective cover 14 by bolts) to expose the screw holes on the end protective cover 14, and then align the mounting holes on the connecting part 21 of the overall disassembly and assembly tool with the screw holes on the end protective cover 14 and fix them with bolts, and then hold the holding part 22 to fix the flip wheel to prevent it from rotating. After the mounting bolts of the flip wheel and the equipment are removed, drag the flip wheel outward through the holding part 22 and then lift it up to complete the separation of the flip wheel from the equipment.

[0026] Disassembly of the disc cam mechanism: After removing the end protective cover 14, the disc cam mechanism is exposed. After removing the outer shaft, the screw 31 of the disc cam mechanism disassembly tool is passed through the disc cam 16 and connected to the inner shaft of the flip wheel through the sink hole 32 (the screw 31 is moved axially by rotating the screw 31, thereby realizing connection and separation with the inner shaft), and then the nut 34 is rotated to make the clamping block 33 press against the disc cam 16, and then the telescopic hand 12 is completely removed to release its connection with the disc cam mechanism connecting rod 17. Under the action of the compression spring 18, the disc cam 16 tends to move toward the outer end, and then the nut 34 is rotated outward. Under the action of the compression spring 18, the disc cam 16 is gradually withdrawn outward, and finally the disc cam mechanism is disassembled.

[0027] When installing the flip wheel, just follow the disassembly process in reverse.

[0028] Compared with the prior art, the utility model has the following beneficial effects:

DETAILED DESCRIPTION

[0044] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0045] Example 1

[0046] This embodiment provides a flip wheel disassembly and assembly kit, including: an overall disassembly and assembly tool and a disc cam mechanism disassembly and assembly tool, wherein the overall disassembly and assembly tool is used to disassemble and assemble the flip wheel as a whole, and the disc cam mechanism disassembly and assembly tool is used to disassemble and assemble the disc cam mechanism at the front end of the flip wheel.

[0047] like Figure 2-3 As shown, the overall disassembly and assembly tool includes: a connecting part 21 and a gripping part 22. The connecting part 21 is a disc-shaped structure, with a sinking platform 23 in the middle and mounting holes matching the screw holes of the end protection cover 14 around it. When in use, the connecting part 21 is fixed to the end protection cover 14 by bolts, and the end of the transmission shaft (outer shaft of the flip wheel) of the disc cam mechanism is located in the sinking platform 23. The gripping part 22 is located at the end of the connecting part 21 away from the end protection cover 14. By holding the gripping part 22, axial rotation can be avoided when disassembling and assembling the flip wheel, thereby avoiding the situation where the maintenance personnel are clamped by the telescopic hand 12.

[0048] Specifically, Figure 4 As shown, when disassembling the flip wheel, first remove the outer shaft protective cover 15 at the outermost end of the flip wheel to expose the screw holes on the end protective cover 14, then align the mounting holes on the connecting part 21 with the screw holes on the end protective cover 14, and fix them with bolts, then hold the holding part 22 to fix the flip wheel to prevent it from rotating. After the mounting bolts of the flip wheel and the equipment are removed, drag the flip wheel outward through the holding part 22 and then lift it up to complete the separation of the flip wheel from the equipment.

[0049] After the turning wheel is separated from the equipment, the parts of the turning wheel need to be disassembled, and then the end protection cover 14 is removed to expose the disc cam structure at the outer end of the turning wheel. The disc cam structure is disassembled using the disc cam mechanism disassembly tool. Figure 5As shown, the assembly and disassembly tool of the disc cam mechanism includes: a screw 31, a clamping block 33 and a nut 34. A sink hole 32 is provided at one end of the screw 31, and the sink hole 32 is provided with an internal thread for connecting the inner shaft of the flip wheel; the other end of the screw 31 is a hexagonal structure 35, which is used to rotate the screw 31 to install the screw 31 on the inner shaft of the flip wheel. The clamping block 33 and the nut 34 are integrally formed, and the nut 34 is located on the side of the clamping block 33 away from the disc cam 16. When in use, the clamping block 33 fits the end face of the disc cam 16, and the clamping block 33 is moved axially along the screw 31 by rotating the nut 34, thereby slowly withdrawing the disc cam 16 or slowly pushing it onto the flip wheel body.

[0050] Furthermore, a clamping assembly is provided on one side of the clamping block 33 close to the hexagonal structure 35, and the clamping assembly includes: two symmetrically arranged clamping bodies 41, both of which are hinged to the clamping block 35, and a handle 42 is provided on the clamping body 41. The two clamping bodies 41 clamp the hexagonal structure 35 after closing, and the screw 31 can be rotated by holding the two handles 42 to achieve the screwing in / out of the screw 31, so as to complete the installation and disassembly of the disc cam mechanism disassembly tool. When in use, the screw 31 passes through the middle of the disc cam 16 and then extends into the inside of the flip wheel, and is threadedly connected to the end of the inner shaft of the flip wheel through the sinking hole 32. After completing the installation of the screw 31, the two clamping bodies 41 are opened, and the handle 42 is pushed to rotate the clamping block 33, thereby pushing the disc cam mechanism inward for installation or withdrawing it outward for disassembly.

[0051] Specifically, the disassembly process of the disc cam mechanism is as follows: after the flip wheel is separated from the equipment and the end protective cover 14 is removed, the disc cam structure at the outer end of the flip wheel is exposed, and then the outer shaft is removed, and the connection of the remaining inner shafts is released. The two clamping bodies 41 clamp the hexagonal structure 35 and then rotate to connect the screw 31 to the inner shaft, and then unfold the clamping body 41, rotate the clamping block 33 to make it fit the outer end surface of the disc cam 16, and then completely remove the telescopic hand 12 to release its connection with the disc cam mechanism connecting rod 17. Under the action of the compression spring 18, the disc cam 16 tends to move toward the outer end, and then the clamping block 33 is rotated outward, and under the action of the compression spring, the disc cam 16 gradually withdraws outward, and finally the disc cam mechanism is disassembled.

[0052] like Figure 8-11 As shown, when installing the disc cam mechanism, first connect the screw rod 31 with the inner shaft, then rotate the clamping block 33 to push the disc cam 16 inward, drive the connecting rod to extend forward, and after it is in place, install the telescopic hand 12. After the telescopic hand 12 is fully installed, the disc cam mechanism disassembly tooling can be removed.

[0054] In this embodiment, the screw rod 31 is screwed by a hexagonal wrench matched with the hexagonal structural member 35 , and a hand wheel 5 is provided on the nut, and the rotation of the nut 34 and the pressing block 33 is realized by the hand wheel 5 .

[0055] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
