Description

High efficiency polishing machine

Technical field

The invention relates to the technical field of processing equipment, in particular to an efficient polishing machine.

Background technique

The traditional tile polisher design is generally suitable for tile polishing of sizes less than 800x800 to 1000x1000mm. With the increasing demand of consumers, there are new requirements for ceramic tile products: 1. The area of a single tile is required to be larger; 2. The polishing quality is required to be high.

The existing polishing machine, when it is necessary to achieve the grinding of large-area tiles, will face the following core problems:

1. When polishing large-area tiles, the production efficiency is too low: because the tile area is too large, it means that the area to be polished by a single grinding head needs to be increased accordingly (that is, the swing amplitude of a single grinding head needs to be set larger. In other words, a single grinding head requires more working time based on the fact that each grinding head guarantees an equivalent amount of polishing work. That is, if the polishing effect is required, the feeding speed of the tile conveying line will have to be greatly reduced to meet the needs of the polishing operation. Therefore, there is a core problem that the efficiency of the polishing operation is too low.

2. If you want to ensure the efficiency of the polishing operation of large-area tiles, you need to ensure that the feeding speed of the tile conveying line is constant or faster, so it is necessary to increase the polishing area of the grinding head by other schemes.

In order to solve the above problems, the following schemes can be used alone or in combination, but the effects are not satisfactory, as follows:

(1) Speed up the swinging speed of the swinging beam or add a polishing line:

Due to the increase of the polishing area, in order to ensure the efficiency of the polishing operation, it is necessary to speed up the speed of the tile conveying line, so that the swinging speed of the swinging beam must be greatly increased in synchronization. In addition, it is also possible to increase the polishing area by adding a polishing line in the direction of the feed and adding a set of grinding heads.

The problem with this solution is that, due to the increase in the polishing area, the amplitude of the swing of the single grinding head is larger, which tends to cause uneven polishing. For example, different grinding heads may overlap or partially overlap the position of the tile polishing, which may result in uneven polishing, which is more serious due to the greater amplitude of the grinding head.

Even if one or more polishing lines are added to theoretically increase the area of the sanding, it is also impossible to avoid the overlap of the polishing position and the presence of a position that is not sufficiently polished.

In addition, the addition of polishing lines also takes up more work space and greater operating costs.

(2) Increase the diameter of the polishing head:

In principle, the addition of a polishing head does increase the area of the sanding, but it is not feasible to increase the diameter of the polishing head due to the smoothness of the polishing head and power loss. If the grinding head is added in the direction of the feed, it is consistent with the problem of "adding a polishing line".

detailed description

The present invention will be further described below in conjunction with the drawings and specific embodiments.

An efficient polishing machine as shown in FIGS. 1-5 includes a conveying mechanism 40, at least two sets of polishing assemblies 10, and a first driving mechanism 20, and the specific conveying mechanism 40 can convey the external workpiece 60 to be processed in the first direction. At least two sets of polishing assemblies 10 are used to polish the surface to be processed of the workpiece 60 to be processed; and at least two sets of polishing assemblies 10 are spaced apart in the second axial direction. The first driving mechanism 20 can be used to drive at least two sets of polishing assemblies 10 to reciprocate in the second direction. And intersecting the first direction with the second direction.

In this embodiment, the workpiece 60 to be processed is a ceramic tile, and two sets of polishing components 10 are provided as an example, and the conveying mechanism 40, the two sets of polishing components 10, and the first driving mechanism 20 can be mounted on a base. The first direction may be the Y-axis direction (ie, the length direction of the pedestal), and the second direction may be the X-axis direction (ie, the width direction of the pedestal).

Based on the above structure, when the high-efficiency polishing machine of the present invention is used, the ceramic tile to be processed is transported by the transport mechanism 40 along the length of the susceptor, and during the transport process, the two sets of polishing components 10 are to be processed by the tile to be processed. Surface processing. Since the two sets of polishing assemblies 10 can reciprocate along the width direction of the base under the driving of the first driving mechanism 20, That is to say, two sets of polishing assemblies 10 are simultaneously processed in the width direction of the processed surface of the tile to be processed, so that when the surface to be processed of the tile to be processed is too wide, it is not necessary to change the single set of polishing components 10 at the base. The amplitude of the swing in the width direction avoids the problem of uneven polishing caused by the excessive swing amplitude of the single-group polishing assembly 10, thereby ensuring the feed speed, improving the polishing efficiency and quality.

The polishing assembly 10 described above is not limited to the above two groups, and may be specifically set according to the actual width of the tile to be processed.

At the same time, the first direction and the second direction can also be obliquely intersected in both directions. And the first direction and the second direction may also have two directions in which the curves do not intersect. In addition, it should be noted that the processing surface formed by the two groups of polishing assemblies 10 in the width direction of the pedestal may be larger than the surface to be processed in the width direction of the ceramic tile, so that the width direction of the ceramic tile can be ensured when the two sets of polishing assemblies 10 reciprocate.

During the rotation of the drive shaft 21, the transmission gear 23 fixed to the end of the drive shaft 21 will rotate accordingly, and the transmission gear 23 is driven. Engaged with the transmission rack 22, the swinging beam 30 is moved along the extending direction of the rack (i.e., the width of the base) during the rotation of the transmission gear 23.

Further, the transmission shaft 21 may specifically include a plurality of shaft segments, and the adjacent two shaft segments are synchronously coupled by the coupling, so that the disassembly and assembly work when the transmission shaft 21 is too long may be facilitated.
