DETAILED DESCRIPTION

[0019] A preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.

[0020] To achieve the above purpose, the embodiments of the present invention adopt the following technical solutions: Figure 1, a chip blowing and removal device for an automatic grinder comprises a grinding and protection mechanism, a grinding tool 20, an air jet mechanism and a chip collecting mechanism, wherein the grinding and protection mechanism is formed with a waste chip accommodating chamber, and the grinding tool 20 is built in the aforementioned grinding and protection mechanism, and the air jet mechanism is used to blow air into the grinding area of ​​the grinding tool, thereby blowing high-pressure gas toward the tool edge of the grinding tool 20, and using the gas impact force to blow electrode chips away from the grinding area, and the chip collecting mechanism is connected to the waste chip accommodating chamber of the grinding and protection mechanism for collecting waste chips. When in use, the grinding tool is used to grind the electrode head. Due to the removal of the electrode head material and the operation of the grinder, a large amount of waste chips will be generated. The waste chips are generally adhered to the grinding blade and accumulated in the chip removal hole of the grinding tool. Air is blown into the electrode grinding area by the air jet mechanism, and the electrode chips are blown away from the grinding area by the high-pressure gas, and the electrode chips blown out from the nozzle are sucked away by the chip collecting mechanism and collected. In addition, the grinding tool of this embodiment is different from the conventional grinding tool, and it can have a larger opening, so as to avoid the waste chips from being blocked inside the tool, making it easier to discharge the waste chips. Therefore, this embodiment blows away the waste chips from the grinding area by means of air blowing, chip extraction, and tool optimization, thus realizing an automatic and efficient chip removal function.

[0021] As a preferred technical solution of this embodiment, the grinding and protection mechanism includes an upper protective shell 110 and a lower protective shell 120. The upper protective shell and the lower protective shell 120 are arranged in cooperation with each other, and the two form a waste chip receiving chamber. It should be noted that the upper protective shell 110 and the lower protective shell 120 are fitted together to form a shell structure, and a waste chip receiving chamber is formed inside the shell structure. When in use, the grinding tool 20 is placed inside the shell structure, so that the electrode chips generated during the grinding process can be placed in the above-mentioned waste chip receiving chamber.

[0022] Furthermore, in order to achieve an effective connection between the upper protective shell 110 and the lower protective shell 120, a locking pin 130 and a locking screw 140 are also provided between the upper protective shell 110 and the lower protective shell 120. Specifically, the locking pin 130 is arranged at the ends of the upper protective shell 110 and the lower protective shell 120, and is used to lock and fix the two from the ends; the locking screw 140 can be arranged on the sides of the upper protective shell 110 and the lower protective shell 120, and is used to pass through the two, so as to achieve effective fixation of the upper protective shell 110 and the lower protective shell 120.

[0023] Furthermore, an upper transparent cover 111 is provided on the top side of the inner cavity of the upper protective shell 110; a lower transparent cover 121 is provided on the bottom of the lower protective shell 120. In this way, by utilizing the light-transmitting characteristics of the upper transparent cover 111 and the lower transparent cover 121, the grinding process can be observed in real time, which facilitates the control of the progress of the grinding operation.

[0024] Furthermore, in order to facilitate the installation of the grinding tool 20, a receiving hole matching the grinding tool is provided on the upper transparent cover 111 and the lower transparent cover 121. When in use, the grinding tool is installed into the upper protective shell 110 and the lower protective shell 120 through the aforementioned receiving hole.

[0025] Reference Figure 2 As a preferred technical solution of this embodiment, the jet mechanism includes a nozzle 310, which is arranged on the side wall of the upper protective shell 110 and / or the lower protective shell 120, and the nozzle is arranged in communication with the waste chip containing chamber. It should be noted that the nozzle 310 is a tubular structure with a certain caliber. The nozzle 310 can be arranged on the side wall of the upper protective shell 110, or on the side wall of the lower protective shell 120, or on the common side wall of the upper protective shell 110 and the lower protective shell 120, and the air outlet of the nozzle faces the grinding area of ​​the grinding tool. In addition, the nozzle is also connected to an air source through an air pipe, and the air source sprays gas to the nozzle through the air pipe. The nozzle sprays the gas to the electrode grinding area, and uses high-pressure gas to blow toward the tool edge to blow away the electrode chips from the grinding area.

[0026] As a preferred technical solution of this embodiment, the chip collection mechanism includes a chip extraction shell 410 and a chip collector 420. The chip extraction shell 410 is arranged on the side wall of the grinding protection mechanism. Specifically, the chip extraction shell is arranged on the outer walls of the upper protective shell 110 and the lower protective shell 120, and is connected to the waste chip containing chamber. The chip collector 420 is connected to the chip extraction shell. The chip collector 420 is used to collect electrode chips. Furthermore, the chip collector is a bag made of flame-retardant and cut-resistant material. When in use, the chip extraction shell 410 absorbs the electrode waste chips blown out by the nozzle 310, and finally transports the electrode chips to the chip collector 420 for storage.

[0027] Furthermore, the chip extraction shell 410 is fixed to the side wall of the grinding protection mechanism by a positioning pin 430. Specifically, the chip extraction shell 410 can be fixedly connected to the side wall of the lower protective shell 120 by a positioning pin, and the chip extraction shell is connected to the waste chip containing chamber; in addition, a bent pipe is provided inside the chip extraction shell for guiding the airflow to the chip collector 420. The built-in bent pipe can be a copper bent pipe, which guides the airflow of compressed gas to the chip collector. The negative pressure formed by the high-speed flow of the airflow can guide the electrode waste chips to fall into the chip collector along the conduit.

[0028] Furthermore, the chip collector 420 is provided with an exhaust hole, and the compressed gas flow can be discharged through the exhaust hole on the chip collector.

[0029] The utility model also provides an automatic grinder, comprising the aforementioned chip blowing and removing device for the automatic grinder.

[0030] When in use, the grinding tool 20 is built into the grinding protection mechanism to ensure that the electrode waste generated during the grinding process is isolated inside the grinding protection mechanism. At the same time, the grinding tool 20 is different from the conventional grinding tool. It has a larger opening, which can prevent the waste from clogging inside the tool and make it easier to discharge the waste. The nozzle 310 is a tubular structure with a certain caliber, and its air outlet is set toward the electrode grinding area. When the compressed gas passes through the nozzle 310, it will be ejected at a high speed and a certain angle, so as to blow away the electrode chips in the electrode grinding area and prevent the waste from sticking to the inside of the grinding tool 20. The chip extraction shell 410 has a built-in copper elbow, which guides the airflow of the compressed gas to the chip collector 420 and discharges it through the exhaust hole on the chip collector. The negative pressure formed by the high-speed flow of the airflow can guide the electrode waste to fall into the chip collector 420 along the conduit.
