Description

Plug-in tile polishing device

technical field

The invention relates to the field of ceramic product processing machinery design, in particular to a plug-in ceramic tile polishing device.

Background technique

At present, due to the improvement of people's living standards and aesthetic concepts, higher requirements are placed on the quality and surface roughness of ceramic products. Among them, ceramic polished tiles are one of the most widely used ceramic products in modern architectural decoration projects. .

With the continuous update and development of my country's building decoration materials (tiles, stone, etc.), the daily output of ceramic tiles is increasing. In 2008, the daily output of each ceramic tile production line was 13,000 square meters. In 2013, the daily output of ceramic tiles reached 23,000 square meters. meters, which requires tile processing equipment must adapt to the requirements of large output and heavy load.

However, the structure of the existing tile polishing grinding head device limits the improvement of the processing efficiency of the tile polishing grinding head. Unable to meet the needs of current production, it is urgent to improve efficiency. Specifically, among the existing ceramic tile polishing grinding head devices, the swing type polishing grinding head is most widely used.

As shown in Figure 1, the motor 1' in the oscillating polishing grinding head drives the main shaft 3' to rotate through the pulley, and the main shaft 3' drives the grinding head to rotate; at the same time, the main shaft 3' drives the gear 5' to rotate through a rigid connection, and the gear 4' It meshes with gear 5' and gear 6', and forms a gear transmission device inside the grinding head. The gear transmission device reduces the speed of the main shaft 3' and drives the cam 7' to rotate. The cam 7' presses the two rollers 11 of the pendulum 10' ', make the pendulum 10' move up and down, then the grinding block seat 8' and the grinding block 9' swing left and right, so that the grinding block 9' and the adobe are in line contact, thereby controlling the swing frequency of the grinding block seat 8.

It can be seen from the above that the oscillating polishing grinding head includes two sets of operation systems of "grinding head rotation" and "cam rotation". These two systems are related to each other, and the power is driven by the same motor. Among them, the two systems are integrated inside the grinding head. Due to the narrow internal space of the grinding head, under the constraints of size, the difference between the revolution speed of the grinding head and the rotation speed of the cam can only be achieved by one tooth, which brings difficulties for speeding up the grinding head. ; At the same time, the "grinding head rotation" needs to use the belt pulley to change the speed, and then carry out the first-stage transmission, while the "cam rotation" needs to go through the three-stage transmission and speed change, so that the gear transmission is easy to appear in the assembly and maintenance. In addition, if the processing efficiency of the grinding head is improved by increasing the speed of the grinding head, the speed of the cam will also increase, because the wave-shaped cam drives the pendulum to swing, and the gap between the roller and the cam will make the gap between the roller and the cam In addition, the high-frequency swing of the grinding block will produce severe vibration, which may break the tiles. The noise is large and the performance is unstable, which seriously affects the improvement of the processing efficiency of the tile polishing grinding head device.

It should be noted that the oscillating motion of the grinding block seat 70 makes the grinding block 71 always in linear contact with the ceramic tile. The grinding motion of the grinding block 71 is a compound motion composed of two kinds of motions: "the circular rotation of the grinding block 71 around the main shaft 64 of the grinding head" and "the left and right rotation and swinging of the grinding block 71 around the swing arm", so that the grinding block 71 and the ground The planes are in linear contact, the grinding pressure is strong, and the grinding block 71 swings left and right, and the pure abrasive grains can quickly squeeze out new processing edges and corners during this swing, and at the same time, the processed sand can also be compared with the pure abrasive grains. The grains are conveniently discharged in the left and right movement without blocking the gap of the grinding block 71.

Correspondingly, the swinging device for the grinding block seat also includes a grinding head upper casing 60, a grinding head lower casing 68 and an upper casing connecting bearing 61, and the grinding head lower casing 68 is connected to the grinding head main shaft 64 and the grinding head upper The boxes 60 are respectively connected, and the upper box 60 of the grinding head is connected with the cam connection bushing 62 through the upper box connecting bearing 61 .

It can be seen from the above that the plug-in tile polishing device of the present invention is formed by plugging the high-speed grinding head integrated drive module, the cylinder moving module and the grinding head module, which are convenient for installation and maintenance and low in cost. At the same time, the high-speed grinding head integrated drive module and the cylinder moving module are separated from the outside of the grinding head module, so that the volume of the grinding head module is reduced, the weight is reduced, and the vibration is reduced. In addition, the grinding head spindle 64 directly drives the grinding head to revolve at high speed, and at the same time directly drives the wave cam 67 to rotate through the planetary structure, which has a compact structure and high transmission efficiency. And the revolution of grinding head and the rotation of wave cam 67 are no longer associated, and the drive and motion of the two are independent of each other, which brings a lot of space for the speed-up of grinding head. At the same time, the internal structure of the grinding head is greatly simplified, reducing the failure rate.
