Description
Technical Field
The invention relates to the technical field of cigarette making machines, in particular to a tool and a method for mounting and dismounting a separating wheel end cover.
Background
Currently, the cigarette separating wheel of the cigarette making machine is used for separating single-length cigarette strips which are delivered by the first cutting wheel and are tightly connected together, the process flow is shown in fig. 1, and the process flow in fig. 1 comprises: a tobacco receiving wheel A, a primary cutting wheel B and a separating wheel C. The rear part of the separating wheel is provided with a cylindrical cam which is fixed on a machine wallboard, when in normal operation, the cigarette separating wheel rotates to drive a cam follower (namely a roller on the push rod) to rotate along the contour of the cam, so that 12 push rods are driven to do reciprocating linear motion on the surface of the separating wheel, and the structure of the separating wheel is shown in figure 2.
The contact surfaces of the roller and the cam are easily abraded due to rolling friction, so that the roller is damaged due to uneven stress, especially in a high-speed machine type; secondly, because the operating characteristics of the push rod and the linear bearing are easy to wear, the roller and the linear bearing on the separating wheel need to be replaced frequently after being used for a period of time, and the separating wheel assembly needs to be disassembled.
As shown in fig. 2, on 12 push rods 100 of the separating wheel, the motion position of the slider is determined by the cam profile curve, each push rod is reset corresponding to one spring 200, the spring force is large, when the end cover 300 of the separating wheel is disassembled, the pressure of the spring needs to be released, if the screw on the end cover is directly screwed off, the end cover can be quickly supported by the push rods due to the action of the huge spring force of 12 compression springs, and the personal injury of the disassembling personnel can be caused in serious cases. During installation, the end cover is easy to incline due to large elasticity and uneven stress, and the end cover is often required to be repeated for many times, so that the screw and the threaded hole are easy to damage. Thus, disassembly and assembly is time and labor consuming.
The technical scheme in the prior art is as follows:
1) When the separating wheel end cover is disassembled, in order to ensure personal safety, a plurality of personnel are required to press the end cover with force, the end cover screw is loosened slowly, and the spring stress is released.
2) When the separating wheel end cover is installed, in order to ensure personal safety, a plurality of persons are required to press the end cover forcibly, and the screw on the end cover can be screwed down after the spring is compressed to a certain degree.
3) At present, no auxiliary tool is provided in the industry for realizing the disassembly and the assembly of the end cover of the separating wheel.
The prior art has the following disadvantages:
1) The separating wheel has 12 springs in total, the elasticity is large, a plurality of maintenance personnel are required to participate in the disassembly and the assembly together, and certain potential safety hazards exist.
2) When installation separating wheel end cover, need evenly push down and contract 12 springs through the end cover, because everyone pushes down the power that the end cover used different, very easily causes the end cover slope, the screw installation is just more difficult, and has the hidden danger that some spring is not correctly installed, leads to the installation back to correspond the slider action and is not smooth even not move, produces and touches the wrinkle cigarette, need pull down again and reprocess, has reduced equipment efficiency.
Therefore, how to provide a tool and a method for mounting and dismounting a separating wheel end cover becomes a technical problem to be solved urgently in the field.
