Description

Roller mill grinding roller supercharging vibration absorbing device Technical Field The utility model relates to the technical field of roller mill equipment, in particular to a roller mill grinding roller pressurizing vibration absorbing device. Background The roller mill is one kind of crushing equipment for mine, metallurgy, building material and other industry, and one of the core parts is grinding roller. The grinding roller bears the key effect of extruding and grinding materials in the running process of equipment, and the working state of the grinding roller directly influences the production efficiency, the energy consumption level and the service life of the whole machine. In order to improve the working performance of the grinding roller, in particular to keep stable running under high-pressure and high-vibration environments, a pressurizing and vibration absorbing device is usually required to be equipped to realize effective support and dynamic buffering of the grinding roller. The utility model patent CN 203253484U discloses a pressurizing vibration absorbing device of a grinding roller of a torch roller grinder, which comprises a rotary table arranged on a main shaft, wherein a plurality of pressurizing vibration absorbing grooves are uniformly distributed on the rotary table on the periphery of the main shaft, a pressurizing vibration absorbing assembly is arranged in the pressurizing vibration absorbing grooves, the pressurizing vibration absorbing assembly comprises a push rod and a spring sleeved on the push rod, the upper end of the push rod is propped against the grinding roller assembly, a pre-pressing sheet is arranged at the lower end of the push rod, and the pre-pressing sheet is fixed on the rotary table through a nut and a bolt. The device is fixed the pre-compaction piece on the carousel through nut and bolt, thereby the reuse ejector pin carries out the pressure boost pretension to the grinding roller subassembly and reaches the purpose that the pressure boost was inhaled and shake to its compact structure does not increase equipment volume, rationally distributed. However, in practice it has been found that the device is not provided with an effective buffer guide. Because the elastic piece (such as a spring) lacks limiting measures of the movement direction in the shock absorption process, the elastic piece is easy to deviate or twist in the compression or rebound process, and uneven stress is caused. The unstable motion state not only weakens the vibration absorbing effect, but also accelerates the fatigue damage of the elastic element, obviously shortens the service life of the elastic element, and simultaneously can cause abnormal vibration and even failure of the grinding roller assembly, thereby affecting the operation safety and stability of the whole machine. Therefore, in order to solve the above-mentioned problems, a pressurizing and vibration absorbing device for the grinding roller of a roller grinder is needed. The novel device can be additionally provided with a reasonable guiding and limiting mechanism on the basis of keeping the compact structure, effectively control the movement track of the elastic element, improve the vibration absorption efficiency and the system stability, prolong the service life of the device, better meet the high-standard requirements of modern industrial production on high efficiency, safety and continuous operation, and provide powerful support for the technical upgrading of equipment in related industries. Disclosure of utility model The utility model aims to provide a roller pressurizing and vibration absorbing device of a roller mill, which solves the problem that an effective buffering and guiding structure is not arranged in the prior art. Because the elastic piece lacks the spacing measure of direction of motion in the shock absorption process, lead to its skew or distortion phenomenon easily to appear in compression or resilience in-process, and then cause the uneven problem of atress. In order to achieve the aim, the utility model provides a roller pressurizing and vibration absorbing device of a roller mill, which comprises a mounting plate and two mounting rods, wherein the two mounting rods are respectively connected to two side positions of the mounting plate; One side of each mounting rod is connected with a grinding roller through a rotatably connected suspension roller bracket, the top of the mounting plate is provided with a top plate, the top plate is connected with the top of the mounting plate through a plurality of support columns, the bottom of the top plate is provided with a top cylinder and a bottom cylinder, the top cylinder is connected with the bottom cylinder through an elastic piece, the bottom of the bottom cylinder is connected with a guide rod, one end of the guide rod penetrates through the mounting plate in a sliding mode, and the top of the top cylinder is connected with the top of the top plate thro
