Glass-ceramics has a wide range of applications in many fields such as building materials, electronic devices, optical instruments, etc. due to its unique physical and chemical properties such as high strength, high hardness, good thermal stability and chemical stability. Before the melting processing of glass-ceramics, the raw materials need to be mixed and then introduced into the interior of the melting equipment. However, since the raw materials are generally introduced into the interior of the melting equipment from the top feeding port, the falling of the raw materials will have a certain impact, causing the raw materials to rebound and splash after contacting the bottom of the interior of the melting equipment, which will cause impact on the interior of the melting equipment and easily damage the melting equipment. SUMMARY

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.

[0018] Example 1

[0019] Please see Figure 1 A melting device for processing microcrystalline glass with a flipping function includes: a melting box 1, a heating element 2 (electric heating device for heating and melting raw materials) in the inner cavity of the melting box 1, a discharge port 3 at the bottom of the melting box 1, a baffle 4 rotatably provided at the bottom of the inner cavity of the melting box 1 for blocking the discharge port 3, a driving element 5 (motor) at the bottom of the inner cavity of the melting box 1, and the output shaft of the motor connected to the baffle 4; a feed port at the top of the melting box 1, a telescopic element 6 at the top of the melting box 1, a mixing box 7 on the moving end of the telescopic element 6, and a discharge conduit 10 connected to the bottom of the mixing box 7, the bottom end of the discharge conduit 10 being inserted into the inner cavity of the feed port.

[0020] Please see Figure 1 The mixing chamber 7 is equipped with a stirring mechanism 8 (the stirring mechanism 8 includes a motor, a stirring shaft mounted on the output shaft of the motor, and blades mounted on the stirring shaft. The motor is mounted on the outer wall of the mixing chamber 7, and the stirring shaft and blades are located in the inner cavity of the mixing chamber 7). The top of the mixing chamber 7 is connected to a feed pipe 9, and a partition 11 is slidably provided at the bottom of the inner cavity of the mixing chamber 7 (the partition 11 can move left and right). The partition 11 is used to block the discharge conduit 10, and a power component is provided on the partition 11.

[0021] Please refer to Figure 1 and Figure 2 The power component is a pull rope 12, which is located between the partition 11 and the kit 61. The telescopic component 6 includes the kit 61 and a support rod 62 that is slidably installed in the kit 61. The kit 61 is installed on the top wall of the melting tank 1. The support rod 62 is connected to the mixing tank 7. A support spring 63 is provided between the kit 61 and the support rod 62. A limiting groove 64 is provided on the side wall of the support rod 62. An installation groove is provided on the inner side wall of the kit 61. A limiting block 65 is slidably installed in the inner cavity of the installation groove. The end of the limiting block 65 away from the kit 61 is inserted into the inner cavity of the limiting groove 64. An elastic element 66 (spring) is provided between the limiting block 65 and the installation groove. A second electromagnet 67 is provided on the side wall of the kit 61. The limiting block 65 is made of a metal material that can be magnetically attracted, such as iron.

[0022] It should be noted that a return spring is installed between the partition 11 and the mixing box 7.

[0023] Working principle: Raw materials are added into the inner cavity of the mixing chamber 7 through the feed pipe 9. Then, the stirring mechanism 8 is activated to mix the raw materials. After mixing, the stirring mechanism 8 stops working. The second electromagnet 67 is energized to generate magnetic force, which is used to attract the limiting block 65, removing the limiting block 65 from the inner cavity of the limiting groove 64 and releasing the restriction on the support rod 62. Because the mixing chamber 7 is filled with raw materials, its gravity is greater and it moves downward, allowing the feeding guide tube 10 to enter the inner cavity of the melting chamber 1. As the mixing chamber 7 gradually moves downward, the pull rope 12 begins to tighten. When the mixing chamber 7 moves to the point where it can no longer move, the pull rope 12 also moves the partition 11, opening the feeding guide tube 10. At this time, the distance between the bottom end of the feeding guide tube 10 and the bottom of the inner cavity of the melting chamber 1 is small, making the mixing chamber... The raw materials inside the mixing box 7 enter the inner cavity of the melting box 1 through the feeding conduit 10. As the amount of raw materials inside the mixing box 7 decreases, the weight of the mixing box 7 decreases. Under the action of the support spring 63, the mixing box 7, along with the feeding conduit 10, gradually moves upward. While moving upward, the raw materials inside the mixing box 7 are discharged into the inner cavity of the melting box 1, preventing the feeding conduit 10 from being blocked by the raw materials entering the melting box 1, until the mixing box 7 is reset. At the same time, the partition 11 is also reset under the action of the reset spring, re-blocking the feeding conduit 10. Then, the heating element 2 is started to melt the raw materials inside the melting box 1. After completion, the heating element 2 is turned off, and the driving element 5 is activated, causing the baffle 4 to rotate and open the feeding port 3, allowing the molten raw materials to be discharged from the feeding port 3.

[0024] In this embodiment, as a further optimization, please refer to... Figure 2 The end of the limiting block 65 furthest from the second electromagnet 67 has an inclined surface. When the support spring 63 moves the support rod 62 upward, the top of the support rod 62 contacts the inclined surface of the limiting block 65. As the support rod 62 continues to move upward, it will press the limiting block 65 into the mounting groove, so that the top of the support rod 62 passes through the limiting block 65. When the limiting block 65 is aligned with the limiting groove 64, under the action of the elastic element 66, the limiting block 65 moves and inserts into the inner cavity of the limiting groove 64, and re-fixes the support rod 62. After the support rod 62 moves downward, the power supply to the second electromagnet 67 is disconnected, saving energy.

[0025] In this embodiment, as a further optimization, please refer to... Figure 3 , Figure 4 and Figure 5The feeding conduit 10 includes a mounting tube 101, a movable tube 102 slidably inserted into the mounting tube 101, and an elastic element (spring) disposed between the mounting tube 101 and the movable tube 102. A first electromagnet 103 is mounted on the mounting tube 101. A magnetic block is mounted on the side of the movable tube 102 facing the first electromagnet 103. The magnetic blocks and the first electromagnet 103 share the same magnetic poles on their sides (they will generate a repulsive force when they approach each other). A conductive plate 104 is mounted on the outer wall of the mounting tube 101, and a conductive plate 104 is also mounted on the inner wall of the feed inlet. The conductive plate 104 of the feed inlet is located on the positive side of the conductive plate 104 of the mounting tube 101. Below, one conductive sheet 104 is connected to the power supply via a wire, and the other conductive sheet 104 is connected to the first electromagnet 103 via a wire. The power supply is also connected to the first electromagnet 103 via a wire. During the process of the feeding conduit 10 moving down into the melting box 1, when the mixing box 7 can no longer move down, the two conductive sheets 104 come into contact, turning on the power supply to the first electromagnet 103, causing it to generate magnetic force to repel the movable tube 102, causing the movable tube 102 to move down, increasing the length of the feeding conduit 10, and bringing the bottom end of the feeding conduit 10 closer to the bottom of the inner cavity of the melting box 1, further preventing the raw material from rebounding and hitting the inside of the melting box 1, thus reducing the probability of the raw material bouncing back into the melting box 1.
