[0002] A medium frequency furnace is a power supply device that converts 50Hz AC power into medium frequency (300Hz to 1000Hz). It rectifies the three-phase AC power into DC power, and then converts the DC power into an adjustable medium frequency current. It supplies the medium frequency alternating current flowing through the capacitor and induction coil, generating high-density magnetic lines in the induction coil, cutting the metal material contained in the induction coil, and generating large eddy currents in the metal material.

[0003] At present, the medium frequency furnace temperature control display screen is one of the most important control units of the medium frequency furnace equipment. Since the sanitary environment in most factories is relatively complex, the medium frequency furnace works in the factory for a long time. Over time, the dust above the factory will inevitably fall on the surface of the medium frequency furnace temperature control display screen. If the dust accumulates and contaminates the surface of the temperature control display screen, it will affect the staff's operation of the temperature control display screen.

[0004] Therefore, it is very necessary to invent a dust cover for the temperature control display screen of a medium frequency tempering furnace. Summary of the Invention

[0006] The dustproof assembly includes a clockwork dustproof roll plate, an auxiliary induction rod, an auxiliary positioning rod, and a second positioning groove. One end of the clockwork dustproof roll plate is sleeved on the outer periphery of the auxiliary induction rod, and the other end of the clockwork dustproof roll plate is connected to the auxiliary positioning rod, and a second positioning groove is opened on the side of the auxiliary positioning rod.

[0007] The arc-shaped guide groove includes an arc-shaped guide portion, a positioning cavity and an induction cavity. One end of the arc-shaped guide portion is connected to the induction cavity, and the other end of the arc-shaped guide portion is connected to the positioning cavity.

[0008] The lower part of the support block is connected to a hydraulic mechanism, the lower part of the hydraulic mechanism is connected to a support member, and a rotating shaft is provided inside the support member.

[0009] The outer side surface of the support member is connected to a U-shaped support frame, the inner side of the U-shaped support frame is connected to a spring, and the lower part of the spring is connected to a scraping and cleaning component.

[0010] The scraping and cleaning assembly comprises a scraping tip and a receiving groove, and the upper portion of the receiving groove is connected with the scraping tip.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The setting of the clockwork dustproof roll plate of the present invention is that first, the auxiliary positioning rod is pulled toward the positioning cavity. Therefore, in the process of pulling the auxiliary positioning rod, the clockwork dustproof roll plate gradually covers the top of the screen assembly, thereby preventing dust from falling from the top.

Implementation Method

[0021] The present invention will be further described below with reference to the accompanying drawings: Example

[0022] As attached Figure 1 To the attached Figure 4 shown

[0023] The utility model provides a dust cover for a temperature-controlled display screen of a medium-frequency tempering furnace, comprising a support frame 1, characterized in that a screen assembly 10 is provided in the middle of the support frame 1, and a support block 11 is connected to the upper end of the support frame 1, an arc-shaped guide groove 2 is provided inside the support block 11, a dust-proof assembly 3 is provided inside the arc-shaped guide groove 2, and a first positioning groove 110 is provided on the side of the support block 11, and the first positioning groove 110 is located at the upper part of the arc-shaped guide groove 2.

[0024] The dustproof assembly 3 includes a spring dustproof roll plate 31, an auxiliary induction rod 30, an auxiliary positioning rod 32, and a second positioning slot 320. One end of the spring dustproof roll plate 31 is sleeved on the outer periphery of the auxiliary induction rod 30, and the other end of the spring dustproof roll plate 31 is connected to the auxiliary positioning rod 32, and a second positioning slot 320 is provided on the side of the auxiliary positioning rod 32. First, the auxiliary positioning rod 32 is pulled toward the positioning cavity 22. Therefore, in the process of pulling the auxiliary positioning rod 32, the spring dustproof roll plate 31 gradually covers the top of the screen assembly 10, thereby preventing dust from falling from the top. When the auxiliary positioning rod 32 reaches the positioning cavity 22, the two corners of the U-shaped pin are respectively clamped into the first positioning slot 110 and the second positioning slot 320, thereby positioning the auxiliary positioning rod 32 inside the positioning cavity 22.

[0025] The arc-shaped guide groove 2 includes an arc-shaped guide portion 21, a positioning cavity 22, and an induction cavity 20. One end of the arc-shaped guide portion 21 is connected to the induction cavity 20, and the other end of the arc-shaped guide portion 21 is connected to the positioning cavity 22. The arrangement of the arc-shaped guide portion 21 is conducive to limiting the mainspring dustproof roll plate 31.

[0026] The support block 11 is connected to a hydraulic mechanism 4 at the bottom, and a support member 40 is connected to the hydraulic mechanism 4 at the bottom. A rotating shaft 5 is provided inside the support member 40, and a rubber cleaning roller 50 is provided on the outer periphery of the rotating shaft 5. The side of the rotating shaft 5 is connected to a motor 51. When it is necessary to clean the dust on the surface of the screen assembly 10, the motor 51 is first turned on to drive the rubber cleaning roller 50 to rotate, and then the hydraulic mechanism 4 is slowly driven to make the rubber cleaning roller 50 slowly contact the screen assembly 10. Therefore, when the rubber cleaning roller 50 rolls on the surface of the screen assembly 10, the friction force generated will wipe off the dust on the surface of the screen assembly 10.

[0027] The outer side of the support member 40 is connected to a U-shaped support frame 6, and the inner side of the U-shaped support frame 6 is connected to a spring 60, and the lower part of the spring 60 is connected to a scraping and cleaning component 61. Since the spring has good buffering characteristics, through the setting of the spring 60, when the scraping and cleaning component 61 cleans the dust on the surface of the rubber cleaning roller 50, the buffering effect of the spring 60 is conducive to the scraping and cleaning component 61 to better scrape and remove the dust on the surface of the rubber cleaning roller 50.

[0028] The scraping and cleaning assembly 61 includes a scraping tip 610 and a receiving groove 620, and the scraping tip 610 is connected to the upper part of the receiving groove 620. When the rubber cleaning roller 50 rolls to wipe the dust on the surface of the screen assembly 10, the scraping tip 610 contacts the surface of the rubber cleaning roller 50. Therefore, the power generated by the rotation of the rubber cleaning roller 50 is used to enable the scraping tip 610 to scrape off the dust on the surface of the rubber cleaning roller 50. In addition, the vibration force generated by the spring 60 is used to vibrate the dust above the scraping tip 610 into the receiving groove 620, thereby making it convenient for workers to clean the dust.

[0029] In the present invention, first, the auxiliary positioning rod 32 is pulled toward the positioning cavity 22. Therefore, in the process of pulling the auxiliary positioning rod 32, the spring dustproof roll plate 31 gradually covers the top of the screen assembly 10, thereby preventing dust from falling from the top. When the auxiliary positioning rod 32 reaches the positioning cavity 22, the two corners of the U-shaped pin are respectively stuck in the first positioning groove 110 and the second positioning groove 320, thereby positioning the auxiliary positioning rod 32 in the positioning cavity 22.

[0030] Utilizing the technical solution described in the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above-mentioned technical effects, all fall within the scope of protection of the present invention.
