Technical Field

[0001] The invention relates to the technical field of crucible processing, and in particular to a crucible cutting machine. Background Art

[0002] As one of the important industries of green energy, the solar photovoltaic industry has a broad future development market. Solar quartz crucible companies are upstream companies in the photovoltaic industry chain and rely heavily on the photovoltaic industry for survival and development. Quartz ceramic crucibles (also known as solar crucibles) are key components of polysilicon ingot furnaces for solar cells. This crucible is a container used in the photovoltaic industry to hold molten silicon and make silicon ingots required for subsequent processes. It is a consumable vessel for pulling large-diameter single crystal silicon and polycrystalline silicon. The working temperature is above 1500℃, and a crucible may be used for each furnace of silicon products produced, which is a consumable item. Thin-walled large-size crucible for polysilicon smelting; Crucible is one of the commonly used containers in the photovoltaic industry. Crucible is a disposable consumable. When placing an order, the square size of the crucible is unchanged, but different customers have different requirements for height size, and even the same customer may ask for different height changes in the middle of the process. Therefore, the manufacturer can only produce the largest height first without prior knowledge, and then cut it according to the height required by different users; In the existing method of cutting crucibles, when cutting, the crucible opening is placed upward, causing the cooling water to enter the inner cavity of the crucible during cutting, so that the cutting wastewater is adsorbed into the micropores of the inner cavity, causing pollution; directly damaging the quality of the crucible, causing huge losses of tens of thousands or even hundreds of thousands to the end customer; How to solve the problem of cooling water not entering the inner cavity of the crucible during crucible cutting is one of the problems that need to be solved urgently; For this reason, we proposed a crucible cutting machine. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a crucible cutting machine which can accurately cut, protect the crucible and reduce the loss.

[0004] The objective of the present invention is achieved in this way: a crucible cutting machine comprises a base, a first motor is arranged inside the base, an output shaft of the first motor is connected to a first rotating shaft, a control panel is arranged outside the base, a workbench is arranged above the base, a supporting platform, a second fixed platform and a first fixed platform are arranged on the first rotating shaft, a second motor is fixedly arranged on the supporting platform, an output shaft of the second motor is connected to a second rotating shaft, the second rotating shaft is threadedly connected to a second fixed platform, the first fixed platform is arranged inside the crucible, pressure sensors are arranged around the second fixed platform, and the outer periphery of the second fixed platform is arranged A buffer pad, a first sleeve is arranged around the workbench, a first stretching rod is arranged inside the first sleeve, a slice is arranged at the front end of the first stretching rod, an arc-shaped protective cover is arranged at the contact position between the first stretching rod and the slice, a second sleeve is arranged around the workbench, a second stretching rod is arranged inside the second sleeve, a chamfering device is arranged at the front end of the second stretching rod, the first sleeve and the first stretching rod, the second sleeve and the second stretching rod are all fixedly connected by bolts, the pressure sensor is wirelessly connected to a control panel, the control panel is electrically connected to a first motor and a second motor, and a sewage outlet is arranged on the side of the workbench.

[0005] The support platform is fixedly arranged on the first rotating shaft.

[0006] The bottom surface of the first fixing platform is provided with a thread groove, and the first fixing platform is threadedly connected with the upper end of the first rotating shaft.

[0007] The material of the buffer pad is silica gel.

[0008] The first stretching rod and the second stretching rod are both L-shaped.

[0009] The second fixing platform can be set in various sizes.

[0010] The beneficial effects of the present invention are as follows: when the present invention is used, the crucible is placed on the support platform, the first fixed platform fixes the bottom of the crucible, and then the second motor is started to raise the second fixed platform. When the pressure sensors around the second fixed platform sense that the pressure applied by the wall reaches the rated value, the pressure signal is converted into a wireless signal and transmitted to the control panel, and then the control panel stops the second motor, so that the second fixed platform is in close contact with the inner wall of the crucible, so that when the crucible is cut, the crucible is not easy to move around, and the cutting accuracy is guaranteed; it also avoids the cooling water from entering the inner cavity of the crucible when the crucible is cut, so that the cutting wastewater is adsorbed into the micropores of the inner cavity, causing pollution to the crucible; the quality damage of the crucible is reduced, and the economic loss is reduced; the slices are set between the second fixed platform and the support platform; The second fixed table can be replaced according to the height required by different users. Since the bottom surface of the first fixed table is provided with a threaded groove, the first fixed table is threadedly connected to the upper end of the first rotating shaft. When the second fixed table needs to be replaced, the first fixed table is first removed, and then a suitable second fixed table is replaced. The second fixed table is provided with a variety of sizes, so it can meet a variety of cutting requirements; buffer pads are provided on the outside around the second fixed table, which can effectively protect the pressure sensor and the inside of the crucible to avoid scratching the inside of the crucible; the setting of the arc-shaped protective cover avoids debris flying around and reduces the cleaning process; the slicing and chamfering devices are both adjustable, so as to facilitate meeting the requirements of different heights; in short, the present invention has the advantages of precise cutting, crucible protection and reduced losses.
