Description

FIELD OF THE INVENTION

[0001] The present invention relates to the technical field of ceramic production, and in particular to a plate polishing method.

BACKGROUD OF THE INVENTION

[0002] The surface polishing of ceramic plates, huge ceramic plates, rock plates and stone plates is an important step of the entire processing. The surface of the plate is continuously polished by a polishing grinding head to make the surface of the plate reach a certain glossiness. The traditional equipment for polishing plates uses multiple polishing grinding heads to sway in unison to polish the plates. However, due to the continuous movement of the plates and the swaying of the polishing grinding heads, the polishing grinding heads bring a motion track on the surface of the plate as shown in figure 1 below, which makes the edge of the plate prone to uneven polishing, missed polishing, and edge yellowing.

[0003] Chinese patent No.: CN208866937U discloses a polishing device for large-sized stone plate. It includes a frame; a belt conveying mechanism; a swing frame slidably installed on the frame through a first linear guide rail extending along the length direction of the frame; a first drive assembly for driving the swing frame to reciprocate along the first linear guide rail; a plurality of movable seats arranged along the length direction of the frame, each movable seat is installed on the swing frame through a second linear guide rail extending along the width direction of the frame, and each movable seat is provided with at least one grinding head; and a plurality of second drive assemblies corresponding to the plurality of movable seats respectively for driving the corresponding movable seats to reciprocate along the second linear guide rail. Although the grinding heads of the polishing device can operate independently, and the grinding heads swing in parallel with and perpendicular to the conveying direction of the plates, so as to avoid the watermelon grain caused by the grinding heads when polishing on the same side of the stone plate surface at the same time, in the course of the retraction of the swing frame, since the retraction direction of the swing frame is opposite to the plate conveying direction, the grinding heads can't sufficiently polish the stone plate surface. Therefore, during the retraction of the swing frame, the stone plate cannot be polished, that is to say, the stone plate needs to be transported at intervals. The polishing device cannot realize continuous production, and the production efficiency is low. Moreover, due to the swing configuration of the swing frame, its structure is complex and prone to failure, which increases maintenance costs and time, and further reduces production efficiency. In addition, the sliding of the movable seats of the polishing device is controlled by pulse, the controllability of the pulse control is poor, and the requirement for the space volume is large, the wiring of the pulse control is difficult, and the problem of signal interference exists when there are too many lines, which leads to the instability of the polishing device.

[0034] In the multi-segment intelligent swing polishing machine of the present invention, each swing beam 4 can swing independently. Adjust the swing speed of the swing beam 4 so that the swinging speed of the swing beam 4 is relatively fast, and the conveying speed of the plate is relatively slow, and the pause time when the swing beam 4 swings in the opposite direction is well controlled, so that the grinding assembly 6 polishes the surface of the plate along a path that forms an approximate square wave shape, as shown in figure 2. This makes the grinding assembly 6 can fully polish the surface of the plate, realizing the continuous production of the plate, that is, two adjacent plates can be transmitted without time intervals, which improves production efficiency, and it has a simple structure, low failure rate, saves maintenance costs and time, reduces production costs, and further improves production efficiency.

[0035] Further, the swinging speed of the swing beam 4 is between 40-80m/min, and the conveying speed of the conveyor 2 is between 20-40m/min. This makes the swinging speed of the swing beam 4 faster than the conveying speed of the conveyor, which makes the surface of the plate be polished fully, and at the same time avoids insufficient grinding due to the excessive swinging speed of the swing beam. Specifically, the conveying speed of conveyor 2 is 30m/min, the swinging speed of the first swing beam is 50 m/min, and the swinging speed of the Nth swing beam is equal to the swinging speed of the N-1 swing beam plus 5 m/min.

[0036] In step 3, during the grinding and polishing of the plate by the grinding assembly 6, the cooling water in the main pipe 9 flows to the surface of the plate after passing through the branch pipe and the through hole in the main shaft 62 in sequence.

[0037] According to the disclosure and teaching of the above-mentioned specification, those skilled in the art to which the present invention belongs can also make changes and modifications to the above-mentioned embodiment. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the invention should also fall within the protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the invention.
