Description

Forming equipment for pressing granular aggregate into plates

Technical Field

The utility model relates to a former for being pressed into panel to granule aggregate.

Background

Natural stone is an important part of building materials, and has been widely used since ancient times because of its diversified colors and easy development. However, the mining of natural stones is gradually restricted due to the excessive increase of the mining amount, the low mining utilization rate, and the like, and particularly, the mining of natural stones is prohibited in european countries. Moreover, the products in each mining area have unique colors and varieties, thereby increasing the difficulty in use. People are always looking for alternatives. With the development of economy, building decorative materials are changing day by day, and synthetic stones are greatly developed as a novel decorative material. However, the matching use of the pressurizing system and the vibrating system of the production equipment is a technical problem, so that the equipment is complex to manufacture, the production and operation are unstable, the maintenance and repair rate is high, and the production efficiency cannot reach the scale. The forming equipment in the prior art mainly has two forms, wherein the first form is a grinding and pressing mode of pressing and vibrating, and the second form is a heavy hammer slapping mode.

The first processing mode, like the utility model patent with Chinese patent number CN201120319813.9, discloses a man-made quartz stone press, which comprises a frame, frames arranged at two sides of the frame, a damping spring arranged at the bottom of the frame, an enclosure frame and a punch arranged on the frame, wherein the frame is provided with a guide pillar, the enclosure frame and the punch are provided with a shaft sleeve, the enclosure frame and the punch are movably connected on the guide pillar through the shaft sleeve, the upper end of the guide pillar is fixedly connected with a machine top, the machine top is provided with a punch hydraulic cylinder and an enclosure frame hydraulic cylinder, the punch hydraulic cylinder is connected on the punch through a hydraulic cylinder connecting seat, the enclosure frame hydraulic cylinder is connected on the enclosure frame through a hydraulic cylinder connecting seat, the bottom of the enclosure frame and the part connected with the punch are provided with a vacuum; a transmission belt is arranged above the frame and the machine base, and transmission wheels are arranged at two ends of the transmission belt. In the technical scheme, pressure is applied through hydraulic pressure, and then vibration is carried out through the vibration motor, but the pressure plate mode has the following defects that as the vibration motor works in high-frequency vibration, a hydraulic system is always in a pressurizing and releasing circulation process, the hydraulic pressure is always in a virtual pressure state, and sufficient pressure cannot be applied to the plate. Meanwhile, the processing mode is similar to a kneading processing mode, materials are kneaded like dough kneading, and the strength of the plate is difficult to improve. In order to meet the sheet forming, a great deal of time is wasted.

The second processing mode, for example, the application of the invention with Chinese patent application No. 201510026692.1, discloses a heavy hammer slapping type synthetic stone preparation process and a forming machine, comprising a base, a heavy hammer mounted on the base and a driver for driving the heavy hammer, wherein the base is provided with a material loading area, and the heavy hammer slaps the material loading area. In the processing mode, the heavy hammer is adopted to slap the materials, and because a large enough slapping force is applied to the materials, the gaps among the particle aggregates are reduced as much as possible, so that the strength of the plate is improved. The second processing mode can effectively solve the defects caused by the first processing mode. The technical scheme of using the heavy hammer to carry out up-and-down slapping can be used for manufacturing high-strength plates by carrying out up-and-down slapping on the particles and the powder materials, but the technical scheme is an up-and-down slapping type implementation mode, and the mode has high requirements on the grade configuration of the ratio of the plate materials. If the grade configuration of the plate materials has deviation, the plate materials can cause the phenomena of cracking, bulging, cavities, material movement deviation and the like due to different motion amounts of the plate materials with different sizes when being flapped by a heavy hammer. The high requirement for the grade configuration of the proportioning brought by the technical scheme can cause the batching precision to have high-precision production standard; the phenomenon that the pressed plates with different sizes are not uniformly distributed on the plates can occur due to inconsistent motion amount of the plate materials with different sizes when the heavy hammer is flapped by the technical scheme; the phenomenon of deformation of the pressed plate during baking can occur due to inconsistent motion amount of plate materials with different sizes when the heavy hammer is flapped. The heavy hammer slapping of the technical scheme is that a plurality of vibrators are driven to be synchronously connected together to form a group of synchronous driving groups, and the heavy hammer is provided with at least one group of synchronous driving groups which are arranged on a heavy hammer plate to realize slapping of the heavy hammer up and down. The technical scheme has high requirements on the synchronous driving set, but the synchronous driving set belongs to a mechanical structure, and the mechanical structure has some errors of processing precision, mounting precision and mechanical operation. Because mechanical errors exist finally, the synchronous driving group cannot realize 100% complete synchronization, so that the existence of the errors can often cause the phenomenon that materials are driven to one side when the slapping plate is pressed, and the phenomenon that the plate is thick and thin at one side occurs. In addition, the heavy hammer slapping, pressurizing and vacuumizing are the novel method and equipment for pressing the particles and powder materials into the plate at present, and the resonance of the plate materials can not realize the thin plate pressing due to the easy strike of the heavy hammer. The technical scheme can be called as a 'slapping' mode, the yield of the plate is improved in the plate industry, but the yield of the plate is seriously influenced, and the instability of the yield is always short of a mature plate forming device and process which are applied in a large scale and have high forming speed.
