DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Embodiment 1
[0024] See also Figure 1-4 A low-temperature co-firing device for ceramic ring ferrite includes a shell 1 and a heating block 16. A mounting frame 9 is arranged inside the shell 1, and four placement plates 15 are fixedly installed on the inner wall of the mounting frame 9. A motor 4 is installed on the top surface of the shell 1, and a second threaded rod 12 is arranged below the motor 4. A resistance plate 14 is threadedly connected to the outer wall of the second threaded rod 12, and the resistance plate 14 is located between the gaps of the four placement plates 15.
[0025] For further information, see Figure 3 A limit block 13 is fixedly installed on the inner wall of the housing 1, and the contact plate 14 is slidably located inside the limit block 13. By setting the limit block 13 and setting the contact plate 14 to be slidable inside the limit block 13, the movement of the contact plate 14 is limited by the limit block 13 and cannot be rotated, and can only move in a predetermined direction.
[0026] For further information, see Figure 3 The number of the second threaded rods 12 is two, and the outer walls of the two second threaded rods 12 are threadedly connected with a contact plate 14. A transmission assembly 5 is connected above the two second threaded rods 12. A mounting frame 3 is fixedly installed on the top surface of the outer shell 1, and the motor 4 is fixedly installed on the bottom surface of the mounting frame 3. The transmission assembly 5 includes two pulleys and a transmission belt, one of which is rotatably connected to the bottom surface of the motor 4, and the second threaded rod 12 is fixedly connected to the bottom surface of the transmission wheel. By setting the transmission assembly 5 and setting a transmission wheel rotatably connected to the bottom of the motor 4, the power of the motor 4 can drive the two second threaded rods 12 to rotate, and the number of the contact plates 14 with a height is two, so that the contact plates 14 can be more stable when supporting the co-fired objects and will not easily cause the objects to fall.
[0027] In specific implementation, the user places the object on the placement plate 15, then puts it inside and starts the heating block 16 for low-temperature co-firing. During the firing process, the object cannot be fully heated, and its placement surface will be blocked by the placement plate 15, so that the object is not heated evenly, thereby affecting the overall quality of the finished product.
[0028] In the present invention, the motor 4 can be started after heating for a period of time, and the two second threaded rods 12 can be rotated simultaneously through the transmission assembly 5. After the two second threaded rods 12 rotate simultaneously, the resistance plate 14 threadedly connected to the outer wall of the second threaded rod 12 is driven upward by the second threaded rod 12, and will rise from the gap between the placement plate 15, and lift the object, so that the covered area of the object can also be fired, so that the object is heated more evenly, and the quality of the finished product is improved.
[0029] By providing the second threaded rod 12 and the abutment plate 14, the device can make the articles fired more evenly during use, improve the quality of the finished products, and increase the practicability of the device.
[0030] Embodiment 2
[0031] Based on Example 1, please refer to Figure 1-4 A low-temperature co-firing device for ceramic ring ferrite, wherein a slide rod 10 is fixedly installed inside the shell 1, a rotatable first threaded rod 11 is installed on the inner wall of the shell 1, a moving block 8 is threadedly connected to the outer wall of the first threaded rod 11, and the moving block 8 is fixedly connected to the mounting frame 9.
[0032] For further information, see Figure 1 The front end of the first threaded rod 11 is fixedly connected with a rotating rod 6, and the rotating rod 6 is provided to make the rotation of the first threaded rod 11 easier.
[0033] In addition, a front cover 2 is fixedly installed at the front end, and two square grooves are penetrated on the outer wall of the front cover 2. A sealing cover 7 is fixedly connected to the front end of the mounting frame 9. The sealing cover 7 is located inside the square groove in the initial state. By setting the square groove, the mounting frame 9 and the sealing cover 7 can be moved out of the square groove.
[0034] During specific implementation, under normal conditions, when the user takes or places items during the firing process, a large amount of heat will be lost inside the device, so that the items inside the device cannot be fired at a stable temperature, which will also affect the firing quality. In this embodiment, the first threaded rod 11 can be driven to rotate by rotating the rotating rod 6. A moving block 8 is threadedly connected to the outer wall of the first threaded rod 11, and one side of the moving block 8 is fixedly connected to the mounting frame 9. Therefore, the mounting frame 9 will be driven to move forward during the rotation of the first threaded rod 11 and move out of the square groove on the front side of the front cover 2. Compared with the traditional method of directly opening the cabinet door, this method undoubtedly reduces the loss of heat and is convenient for placing and taking out items.
[0035] By providing the first threaded rod 11 and the moving block 8, and connecting one side of the moving block 8 to the mounting frame 9, the mounting frame 9 can be pushed out separately, thereby reducing the heat loss inside the shell 1, preventing the temperature change inside the shell 1 from being too large, and maintaining the temperature when firing the object, thereby improving the quality of the finished product.
[0036] Working principle: The user places the object on the placement plate 15, then puts it inside and starts the heating block 16 for low-temperature co-firing. During the firing process, the object cannot be fully heated, and its placement surface will be blocked by the placement plate 15, so that the object is not heated evenly, which in turn affects the overall quality of the finished product.
[0037] In the present invention, the motor 4 can be started after heating for a period of time, and the two second threaded rods 12 can be rotated simultaneously through the transmission assembly 5. After the two second threaded rods 12 rotate simultaneously, the resistance plate 14 threadedly connected to the outer wall of the second threaded rod 12 is driven upward by the second threaded rod 12, and will rise from the gap between the placement plate 15, and lift the object, so that the covered area of the object can also be fired, so that the object is heated more evenly, and the quality of the finished product is improved.
[0038] Under normal conditions, when the user takes or places items during the firing process, a large amount of heat will be lost inside the device, so that the items inside the device cannot be fired at a stable temperature, which will also affect the firing quality. In this embodiment, the first threaded rod 11 can be driven to rotate by rotating the rotating rod 6. A moving block 8 is threadedly connected to the outer wall of the first threaded rod 11, and one side of the moving block 8 is fixedly connected to the mounting frame 9. Therefore, the mounting frame 9 will be driven to move forward during the rotation of the first threaded rod 11 and move out of the square groove on the front side of the front cover 2. Compared with the traditional method of directly opening the cabinet door, this method undoubtedly reduces the loss of heat and is convenient for placing and taking out items.
[0039] By providing the second threaded rod 12 and the abutment plate 14, the device can make the articles fired more evenly during use, improve the quality of the finished products, and increase the practicability of the device.
[0040] By providing the first threaded rod 11 and the moving block 8, and connecting one side of the moving block 8 to the mounting frame 9, the mounting frame 9 can be pushed out separately, thereby reducing the heat loss inside the shell 1, preventing the temperature change inside the shell 1 from being too large, and maintaining the temperature when firing the object, thereby improving the quality of the finished product.
