Technical Field

The present invention relates to a polishing technique.

Background

The existing surface polishing of stone or ceramic plate is generally that the stone or ceramic plate is placed on a transmission belt of a movable frame capable of moving left and right, a polishing wheel is driven by a motor to rotate at a high speed to polish the surface of the stone or ceramic plate moving left and right, the left and right moving speed is constant and the diameter of the polishing wheel is smaller than the width of a ceramic tile, so that the polishing amount obtained at the middle part is more than that at the two sides in the polishing process, the polishing result is the middle depression of the ceramic tile, therefore, someone thinks that the polishing time at the two sides is prolonged by changing the speed in the left and right moving process, but because a rack moving left and right is provided with a power transmission mechanism, the structure is complex, the weight is heavy, the difficulty in speed change control is high, and the cost is high.

Disclosure of Invention

The invention aims to provide the polishing machine which has a simple structure, is easy to control, can balance the polishing amount of each part of the surface of a stone or ceramic plate and avoids the middle depression of a polished product.

The invention is realized by the following steps that the polishing machine comprises a rack, a left-right movement driving power device arranged on the rack, a movable frame driven by the left-right movement driving power device, a power transmission belt arranged on the movable frame, and a power polishing mechanism which is arranged on the rack and is positioned above the power transmission belt and is provided with a polishing wheel.

When the ceramic tile polisher is used, a ceramic tile arranged on the power conveying belt moves forwards under the driving of the power conveying belt, meanwhile, the movable frame driven by the power device is driven to move left and right to further drive the ceramic tile on the power conveying belt to move left and right, when the ceramic tile passes through the power polishing mechanism on the upper surface, the polishing wheel polishes the surface of the ceramic tile, when the movable frame driven by the power device driven by the left and right moving moves in the range between the left and right induction devices, the polishing wheel rotates at a constant rotating speed, after the induction devices sense that the movable frame moves from the middle to the two sides and passes through the left or right induction devices, the alternating current frequency of the alternating current power supply is gradually increased through the frequency conversion module controlled by the control device, so that the rotating speed of the polishing wheel is gradually increased until the movable frame returns under, the alternating current frequency of the alternating current power supply is gradually reduced through the control frequency conversion module of the control device, so that the rotating speed of the polishing wheel is gradually reduced until the position of the sensing device of the left sensing device or the right sensing device is reached, the rotating speed of the polishing wheel is kept constant, the polishing quantity of two sides of the ceramic tile is consistent with the polishing quantity of the middle part of the ceramic tile by changing the polishing rotating speed of the polishing wheel, and the situation of sinking of the middle part of a polished product is avoided. The rotating speed of the polishing wheel is controlled by adopting a frequency conversion mode, so that the polishing amount is conveniently controlled, and the problems of complex structure and difficult control caused by changing the speed of the left-right moving process are solved.

The positions of the left induction device and the right induction device on the rack are set in such a way that when the distance of the movable frame moving from left to right is smaller than the diameter of the polishing wheel, the distance from the left induction device to the middle induction device and the distance from the right induction device to the middle induction device are half of the distance of the polishing wheel diameter deactivation moving frame moving from left to right; when the distance of the movable frame moving from left to right is greater than the diameter of the polishing wheel, the distance from the left sensing device to the middle sensing device and the distance from the right sensing device to the middle sensing device are half of the distance of the movable frame moving from left to right minus the diameter of the polishing wheel.

When the distance that the adjustable shelf from left to right removed is less than the throwing aureola diameter, when the adjustable shelf round trip movement cycle, left side induction system, the ceramic tile surface in the range of motion of the adjustable shelf between the induction system on the right all lasts by the throwing aureola polishing, and cross left side induction system toward both sides, the ceramic tile surface polishing time that the throwing aureola behind the induction system on the right acted on is not continuous, and, along with leave left side induction system or the induction system on the right far away toward both sides, the polishing time on the ceramic tile surface that the throwing aureola acted on is shorter, at this moment, the rotational speed of accessible increases the throwing aureola step by step (like the linear rotational speed that increases the throwing aureola) that increases, effectively compensate the polishing time and shorten and the appearance of.

Similarly, when the distance that the movable frame moves from left to right is greater than the diameter of the polishing wheel, a back-and-forth cycle is performed, the polishing time (polishing amount) obtained on the surface of the ceramic tile within the moving range of the movable frame between the left sensing device and the right sensing device is substantially the same, the polishing amount of the surface of the ceramic tile acted by the polishing wheel passing over the left sensing device and the right sensing device towards both sides begins to decrease, and the shorter the polishing time of the surface of the ceramic tile acted by the polishing wheel is, the smaller the polishing amount is, the longer the polishing time is as the polishing wheel leaves the left sensing device or the right sensing device towards both sides is, at this time, the problem of the small polishing amount caused by the decrease of the polishing time can be effectively compensated by gradually increasing the rotating speed of the polishing wheel (for example, linearly increasing the rotating speed of.

Compared with the prior art, the invention has the advantages of simple structure, easy control, capability of balancing the polishing amount of the surface of the stone or ceramic plate and avoiding the occurrence of the middle depression of the polished product.
