Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production equipment, in particular to a disassembly tool for a rubber roller of a cigarette rolling and connecting unit. Background Art

[0002] The glue roller on the PROTOS70 take-up equipment always runs at high speed with white latex during the operation of the equipment. When the glue scale needs to be cleaned during the after-shift maintenance, the glue roller needs to be removed from the glue roller shaft. Due to the corrosion of the glue scale, the glue roller is sometimes difficult to remove. It requires multiple people to cooperate with screwdrivers, tilt, and hammer to remove it from the glue roller shaft. Even if the glue roller is removed in this way, the surface of the glue roller will be damaged due to a series of operations during the removal process, making the glue roller unusable; and the disassembly process takes about 30 minutes, which is time-consuming and labor-intensive, affecting the effective operation rate of the equipment, and increasing the consumption of accessories, thereby increasing the manufacturing cost.

[0015] The following is a detailed description of an embodiment of the utility model. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0016] See also Figures 1 to 3 This embodiment discloses a disassembly tool for the glue roller of a winding and splicing unit. The glue roller 1 is mounted on the glue roller shaft 2. One end of the glue roller shaft 2 extends out of the glue roller 1 and is provided with a threaded end 3. By screwing a nut on the threaded end 3, the glue roller 1 is press-fitted on the glue roller shaft 2. The inner and outer ends of the outer surface of the glue roller 1 are respectively provided with an inner end annular groove 4 and an outer end annular groove 5.

[0017] The disassembly tool comprises a fixing sleeve 6, a long push rod 7 and a protective sleeve 8. The inner end of the fixing sleeve 6 is open and the outer end is closed by an end plate. The fixing sleeve 6 is placed on the periphery of the upper glue roller 1. The fixing sleeve 6 is provided with two rows of threaded holes, which correspond to the inner and outer annular grooves of the upper glue roller 1. Each row of threaded holes includes at least two threaded holes distributed along the circumference of the fixing sleeve 6. In this embodiment, each row of threaded holes includes three threaded holes evenly distributed along the circumference of the fixing sleeve 6. A limiting bolt 9 is threadedly connected in each threaded hole, and the limiting bolt 9 is embedded in the corresponding annular groove on the upper glue roller 1 to achieve axial limiting of the fixing sleeve 6 and the upper glue roller 1. The end plate of the fixing sleeve 6 is provided with a main screw hole, and the long push rod 7 is threadedly connected to the main screw hole of the end plate of the fixing sleeve 6. The inner end of the protective sleeve 8 is sleeved on the threaded end 3 of the upper glue roller shaft 2. The outer end of the protective sleeve 8 is provided with a positioning groove 10, and the inner end of the long push rod 7 corresponds to the positioning groove 10 of the protective sleeve 8.

[0018] A evasion notch 11 is provided on one side of the fixing sleeve 6 for evading a scraper installed on the rolling and splicing unit.

[0019] When the glue roller 1 needs to be disassembled, first loosen and remove the nut of the threaded end 3 of the glue roller shaft 2, put the protective cover 8 on the threaded end 3 of the glue roller shaft 2, and then put the inner end of the fixed cover 6 on the outer periphery of the glue roller 1 from the outside to the inside, with the avoidance notch 11 facing the scraper, until the inner and outer rows of threaded holes of the fixed cover 6 correspond to the inner and outer annular grooves of the glue roller 1. Then rotate the inner and outer two sets of limit bolts 9 until the inner and outer two sets of limit bolts 9 are respectively embedded in the inner and outer annular grooves of the glue roller 1, so as to realize the axial limit of the fixed cover 6 and the glue roller 1. Then, the outer hexagonal head of the long push rod 7 is rotated with a wrench so that the inner end of the long push rod 7 is against the positioning groove 10 of the protective sleeve 8, and the long push rod 7 is continued to be rotated. Under the action of the threaded cooperation between the long push rod 7 and the fixing sleeve 6, the fixing sleeve 6 is driven to move outward, thereby driving the glue roller 1 to move outward, thereby realizing convenient, safe and non-destructive disassembly of the glue roller 1. The entire disassembly process can be reduced from the original 30 minutes to about 5 minutes, and the disassembled glue roller 1 can be used again, thereby reducing the manufacturing cost.

[0020] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
