Description

Technical Field

[0001] The invention relates to the technical field of liquid crystal glass manufacturing, and in particular to a device for improving the longitudinal cutting quality of semi-finished products. Background Art

[0002] Semi-finished product processing is an important part of the production of liquid crystal glass substrates. Semi-finished product processing is mainly used for horizontal segment cutting, Robot loading, weighing, longitudinal cutting, cooling, thickness measurement, automatic detection, manual sampling, sorting, and unloading of glass after it flows out of the muffle furnace. The process task is to convey, weigh, longitudinally cut, sort, package, and feed the glass plates that have been formed, pulled down, and transversely cut and divided into blocks. In the actual production process, the product is frequently cut and broken longitudinally. The dust generated by cutting and breaking during this period will enter the cutting wheel and cause it to jam, thereby reducing the service life and cutting quality of the cutting wheel, and at the same time affecting the utilization rate of the production line. Summary of the invention

[0020] Figure 2 This is a schematic diagram of the lubricating oil delivery route in the device for improving the longitudinal cutting quality of semi-finished products proposed by the present invention. DETAILED DESCRIPTION

[0021] Reference Figure 1 The present invention provides a device for improving the longitudinal cutting quality of semi-finished products, comprising: a cover body 1 and a cutting wheel 2, wherein:

[0022] The cover body 1 has a receiving chamber 1a and an oil storage chamber 1b located below the receiving chamber 1a. One side of the receiving chamber 1a has an opening, and the oil storage chamber 1b is connected to the receiving chamber 1a. Lubricating oil is stored in the oil storage chamber 1b. The cutter wheel 2 is installed in the receiving chamber 1a, and a part of it passes through the opening of the receiving chamber 1a and is exposed to the outside of the receiving chamber 1a to form a cutting surface. The lower end of the cutter wheel 2 contacts the lubricating oil, so that when the cutter wheel 2 rotates, it continuously passes through the lubricating oil and brings the lubricating oil into the cutting part. This can not only improve the neatness of the incision, but also reduce the flying degree of dust generated by cutting, and then reduce the probability of dust entering the bearing of the cutter wheel 2 and causing the cutter wheel 2 to jam.

[0023] In addition, in this embodiment, a main nozzle 3 is arranged at a position of the cover body 1 above the opening. The main nozzle 3 is connected to an air compressor through a pipeline so that the air compressor delivers high-pressure airflow to it, and the airflow ejected by the main nozzle 3 is directed toward the opening to form an air curtain at the opening, so as to block external dust from entering the accommodating chamber 1a through the air curtain, and form a relatively independent spatial environment inside the accommodating chamber, so that the transmission part of the cutting wheel 2 installed therein is not in contact with the outside world.

[0024] Furthermore, the cover body 1 is provided with a secondary nozzle 4 at a position above the opening. The pipeline connecting the main nozzle 3 and the air compressor is divided into two paths, one of which is connected to the main nozzle 3 and the other is connected to the secondary nozzle 4. The airflow ejected by the secondary nozzle 4 is directed toward the cutting surface, which can not only cool the cutting part, but also prevent the cutter wheel 2 from bringing dust into the accommodating chamber 1a. At the same time, it can also accelerate the volatilization of the lubricating oil, thereby improving the cooling effect on the cutter wheel 2. In order to increase the cooling effect of the lubricating oil on the cutter wheel 2, the lubricating oil in this embodiment is selected from lubricating oil containing harmless volatile substances.

[0025] Furthermore, oiling grooves 2a are provided on the side surfaces of one or both sides of the cutter wheel 2 to increase the amount of oiling on the surface of the cutter wheel 2 .

[0026] In addition, a regulating valve for controlling on-off and adjusting flow rate is installed in the pipeline connecting the main nozzle 3 and the air compressor. During operation, the regulating valve is used to control on-off of the airflow and adjust the flow rate.

[0027] Reference Figure 2 The device for improving the slitting quality of semi-finished products proposed by the present invention further includes an oil storage container 5 for storing lubricating oil, and the oil storage container 5 is connected to the oil storage chamber 1b through a pumping pipeline. During the cutting operation, when the amount of oil stored in the storage chamber is insufficient, the lubricating oil is added to the inside through the oil storage container 5 to ensure that the liquid level in the oil storage chamber 1b always keeps in contact with the bottom of the cutter wheel 2.

[0028] Furthermore, a nozzle 6 with a nozzle toward the cutter wheel 2 is provided in the accommodating chamber 1a. Specifically, the nozzle 6 can be provided on the top and / or the side of the cutter wheel 2. The pumping pipeline is divided into two paths, one of which is connected to the oil storage chamber 1b, and the other is connected to the nozzle 6. During operation, the lubricating oil is sprayed to the cutter wheel 2 through the nozzle 6, which can help the cutter wheel 2 to cool quickly on the one hand, and ensure that the cutting part thereof is filled with lubricating oil on the other hand.

[0029] Furthermore, a regulating valve for controlling the on-off of the pumping pipeline and adjusting the flow rate is installed in the pumping pipeline. During operation, the regulating valve is used to control the on-off of the pumping pipeline and adjust the pumping volume.

[0030] The present invention proposes a device for improving the longitudinal cutting quality of semi-finished products, which also includes a transfer container 7, an oil supply pipeline connecting the transfer container 7 and the oil storage chamber 1b to deliver oil from the transfer container 7 to the oil storage chamber 1b, and an oil return pipeline connecting the transfer container 7 and the oil storage chamber 1b to deliver oil from the oil storage chamber 1b to the transfer container 7, and a cooler 8 is installed in the oil return pipeline. When working, the transfer container 7, the oil supply pipeline and the oil return pipeline are used to realize the circulation of the lubricating oil in the oil storage chamber 1b, and the lubricating oil is cooled during the circulation process to ensure that the lubricating oil entering the oil storage chamber 1b is in a low temperature state, so that the low-temperature lubricating oil can be used to cool the cutting wheel 2.

[0031] Furthermore, a filter 9 is provided in the oil return pipeline and at the front side of the oil inlet end of the cooler 8 , so that the filter 9 can filter impurities in the lubricating oil.

[0032] As can be seen from the above, the present invention provides a cover body 1 on the outside of the cutting wheel 2, and provides an oil storage chamber 1b inside the cover body 1, and lubricating oil is stored in the oil storage chamber 1b, and the lower end portion of the cutting wheel 2 is in contact with the lubricating oil, so that when the cutting wheel 2 performs a cutting operation, its cutting portion is continuously immersed in the lubricating oil and the lubricating oil is brought to the cutting portion. This design can form lubrication at the contact portion between the cutting wheel 2 and the glass during the cutting process, thereby improving the neatness of the incision. At the same time, the lubricating oil wrapped around the cutting portion can reduce the degree of dust flying generated by cutting, thereby reducing the probability of dust entering the bearing of the cutting wheel 2 and causing the cutting wheel 2 to get stuck.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
