Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, specifically to a stone processing edge grinding device. Background Technology

[0002] Edge grinding is a key step in stone processing to improve the aesthetics and durability of finished stone products.

[0003] In existing stone processing edge grinding technology, specialized edge grinding machines are already very mature and can automatically grind the edges of stone and chamfer as needed. However, the existing stone processing edge grinding technology can only adapt to the edge grinding and chamfering of regular stone. When grinding slabs, complicated fixing work is required, and after fixing, the slabs must be fixed accurately and not shifted before subsequent grinding work can be carried out. Thus, the overall work efficiency is too low. Therefore, an improved stone processing edge grinding device is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a stone processing edge grinding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stone processing edge grinding device, comprising a fixed frame, wherein two fixed frames are provided and arranged symmetrically at the top and bottom, and a grinding mechanism for grinding the edge of stone is provided between the fixed frames. The grinding mechanism includes a supporting synchronous wheel, a first motor, a driving synchronous wheel, a transmission synchronous belt, a second motor, and a grinding wheel. Several supporting synchronous wheels are evenly and movably arranged on one side of the surface of the fixed frame via a rotating shaft. A first motor is fixedly arranged on one side of the fixed frame. A driving synchronous wheel is fixedly arranged at the power output shaft end of the first motor. A transmission belt is sleeved on the outer surface of the driving synchronous wheel and the supporting synchronous wheel. Several second motors are evenly and fixedly arranged on the surface of the fixed frame. A grinding wheel is fixedly arranged at the power output shaft end of the second motor.

[0006] Preferably, guide wheels are movably arranged between the fixed frames via rotating shafts. By inserting the stone slab to be edged between the two guide wheels, and then clamping the stone slab with a transmission timing belt and transmitting it towards the edge-grinding wheel, the positioning and clamping of the stone can be automatically completed. No special fixing and alignment are required. The stone can be positioned simply by inserting it between the upper and lower transmission timing belts through the guide wheels, which makes it easy to use and highly efficient.

[0007] Preferably, a number of rubber blocks are uniformly fixed on the outer surface of the transmission synchronous belt. The rubber blocks can tightly clamp and fix the stone. When the stone is between two transmission synchronous belts, the rubber blocks are squeezed on the surface of the stone to produce a certain deformation, so that the stone is firmly clamped and fixed by the two transmission synchronous belts and the rubber blocks.

[0008] Preferably, a water spray head is provided on the surface of the fixed frame on one side of the second motor, which can reduce dust and help cool the stone.

[0009] Preferably, a limiting ring is fixedly provided on the outer surface of the supporting synchronous pulley and the driving synchronous pulley, which can prevent the transmission synchronous belt from falling off the outer surface of the supporting synchronous pulley and the driving synchronous pulley.

[0010] Preferably, the second motor and the grinding wheels are provided in multiple ways and are evenly spaced on the surface of the fixed frame. In this way, the grinding depth of the multiple grinding wheels can be increased sequentially, so as to gradually reach the required grinding depth and angle. This can effectively prevent the stone from cracking due to excessive grinding at one time.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When polishing the edges of stone, this utility model only requires inserting the stone slab to be polished between two guide wheels, and then clamping the stone slab with the transmission timing belt and transmitting it towards the polishing wheel. The positioning and clamping of the stone can be completed automatically without special fixing and alignment. The stone can be positioned simply by inserting the stone between the upper and lower transmission timing belts through the guide wheels, which is convenient to use and has high work efficiency.

[0013] 2. When edging stone, the stone can pass through multiple grinding wheels in sequence under the action of the synchronous belt. The grinding depth of the multiple grinding wheels can be increased in sequence, so as to gradually reach the required grinding depth and angle. This can effectively prevent the stone from breaking due to excessive grinding in one go. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a stone processing edge grinding device, including a fixed frame 1, two fixed frames 1 are provided and arranged symmetrically at the top and bottom, and a grinding mechanism for grinding the edge of stone is provided between the fixed frames 1. The grinding mechanism includes a supporting synchronous wheel 2, a first motor 3, a driving synchronous wheel 4, a transmission synchronous belt 5, a second motor 6, and a grinding wheel 7. Several supporting synchronous wheels 2 are evenly and movably arranged on one side of the surface of the fixed frame 1 through a rotating shaft. A first motor 3 is fixedly arranged on one side of the fixed frame 1. A driving synchronous wheel 4 is fixedly arranged at the power output shaft end of the first motor 3. A transmission belt is sleeved on the outer surface of the driving synchronous wheel 4 and the supporting synchronous wheel 2. Several second motors 6 are evenly and fixedly arranged on the surface of the fixed frame 1. A grinding wheel 7 is fixedly arranged at the power output shaft end of the second motor 6.

[0021] Guide wheels 8 are movably arranged between the fixed frames 1 via a rotating shaft. By inserting the stone slab to be edged between the two guide wheels 8, the stone slab is clamped by the transmission timing belt and transported towards the edge-grinding wheel 7, the positioning and clamping of the stone can be automatically completed. No special fixing and alignment are required. The stone can be positioned simply by inserting the guide wheel between the upper and lower transmission timing belts, which makes it easy to use and highly efficient.

[0022] A number of rubber blocks 9 are uniformly fixed on the outer surface of the transmission synchronous belt. The rubber blocks 9 can tightly clamp and fix the stone. When the stone is between two transmission synchronous belts, the rubber blocks 9 are pressed on the surface of the stone to produce a certain deformation, so that the stone is firmly clamped and fixed by the two transmission synchronous belts in conjunction with the rubber blocks 9.

[0023] A water spray head 10 is provided on the surface of the fixed frame 1 on one side of the second motor 6. The water spray head 10 can reduce dust and help cool the stone.

[0024] A limiting ring 11 is fixedly provided on the outer surface of the supporting synchronous wheel 2 and the driving synchronous wheel 4. The limiting ring 11 can prevent the transmission synchronous belt 5 from falling off the outer surface of the supporting synchronous wheel 2 and the driving synchronous wheel 4.

[0025] The second motor 6 and the grinding wheels 7 are provided in multiple ways and are evenly spaced on the surface of the fixed frame 1. In this way, the grinding and cutting depth of the multiple grinding wheels 7 can be increased sequentially, so as to gradually reach the required grinding depth and angle. This can effectively prevent the stone from cracking due to excessive grinding at one time.

[0026] Working principle: When using this device to polish the edges of stone, simply insert the stone slab to be polished between the two guide wheels 8, and then the stone slab is clamped by the transmission timing belt and transported towards the polishing wheel 7. The positioning and clamping of the stone can be completed automatically without special fixing and alignment. The stone is simply inserted between the upper and lower transmission timing belts through the guide wheels to complete the positioning of the stone, which makes it easy to use and highly efficient.

[0027] The stone, held and secured by the synchronous belt, is aligned precisely with the grinding position of the grinding wheel 7 at its height. As the stone is conveyed forward by the synchronous belt, it is simultaneously ground and edged by the high-speed rotating grinding wheel 7. After the synchronous belt has conveyed the stone a distance to the left, workers can immediately continue feeding more stone for grinding, creating a streamlined grinding process that improves efficiency. Finally, the ground stone is detached from the conveyor and transported to the next workstation by workers or a conveyor belt system.

[0028] Furthermore, when this device is used for edge grinding of stone, the stone can pass through multiple grinding wheels 7 sequentially under the action of the synchronous conveyor belt 5. The grinding depth of the multiple grinding wheels 7 can increase sequentially, gradually reaching the required grinding depth and angle. This effectively prevents the stone from cracking due to excessive grinding in one go. Another advantage is that the low cutting depth each time allows sufficient time for the stone to dissipate heat during grinding and transport, preventing overheating. Therefore, less water is needed for cooling, or even none at all. Of course, this device is still equipped with a spray nozzle structure for unforeseen circumstances.

[0029] It should be noted that the fixed bracket of the device is not shown in the drawings of this application document. In actual use, crossbars and corresponding support crossbars and bracket assemblies of the fixed frame 1 are installed on both sides of the fixed frame 1.
