Description

Technical Field

[0001] This invention relates to the field of ceramic sheet processing technology, and in particular to a sintering apparatus for ceramic sheet processing. Background Technology

[0002] With the increasing application of ceramics, the requirements for sintering quality and dimensional accuracy of ceramic sheet products are gradually increasing. During the sintering process, ceramic sheets are susceptible to warping, deformation, or edge curling due to temperature changes and their own shrinkage, which in turn affects product performance and consistency. Therefore, providing stable support and appropriate pressure for ceramic sheets during sintering is of great importance.

[0003] In existing technologies, ceramic sheets are mostly placed manually one by one onto a firing tray or firing fixture, and then fixed by pressure plates or limiting structures. This method can reduce the displacement and deformation of ceramic sheets to some extent, but manual placement is inefficient, cumbersome, and reduces the sintering efficiency of the ceramic sheets. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a sintering apparatus for ceramic sheet processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sintering apparatus for processing ceramic sheets includes a vacuum sintering machine. A support frame is fixedly installed inside the sintering chamber of the vacuum sintering machine. Multiple horizontal push plates are fixedly installed on both sides of the entrance of the support frame. Multiple pressure frames are fixedly installed above the support frame. A push frame is installed on the outermost pressure frame. Multiple vertical push plates are fixedly installed on both sides of the support frame. The firing rack is horizontally inserted and assembled above the support frame. The firing rack includes multiple firing layers, each layer having multiple ceramic grooves for supporting ceramic pieces. Except for the bottom layer, each layer of the firing rack has a vertical through cavity at one end, and the ceramic pieces pass through the through cavity. The movable frame is pushed and moved by a pusher to transfer ceramic pieces into the ceramic tank; The movable seat is located on the outside of the through cavity of the firing rack and moves in a guiding manner. A horizontal push plate adapted to the horizontal push plate is provided on the outside of the movable seat. Multiple vertical push blocks adapted to the vertical push plate are vertically movably arranged on the movable seat, and each vertical push block is fixedly provided with an insert plate for lifting the ceramic piece and moving it upward.

[0006] Furthermore, in a preferred configuration, the vacuum sintering machine has a door that opens and closes on one side, and a heating ring is installed inside the sintering chamber.

[0007] In addition, the preferred structure is that the top of the support frame is fixedly provided with multiple guide rails, the bottom of the firing frame is provided with guide grooves corresponding to the guide rails, the middle of the firing frame is fixedly provided with a middle plate, and the firing frame is provided with an anti-interference cavity corresponding to the support frame.

[0008] In addition, a preferred structure is that two movable frames are provided above each layer of the firing support on the firing support frame, and the two movable frames of each layer are fixedly connected by a guide plate, and a guide cavity is adapted to be opened on the middle plate corresponding to the guide plate.

[0009] In addition, a preferred structure is that all the pressing frames are adapted to the ceramic sheets, and when the movable frame moves to the outermost side via the push frame, the pressing frames are all located at the top of the ceramic groove and are adapted to press the ceramic sheets.

[0010] In addition, a preferred structure is that fixed uprights are provided on both sides of the support frame facing the end of the firing frame, and multiple horizontal push plates are fixedly provided on the fixed uprights. Multiple horizontal push slopes are provided on the horizontal push plates, and horizontal push slopes are adapted to the horizontal push slopes on the horizontal push plates. The movable seat moves through its slopes.

[0011] Furthermore, in a preferred configuration, the movable seat is provided with multiple adjustable cavities separated by multiple fixed blocks, and the vertical push blocks are all located within the adjustable cavities and move vertically, with the height of the adjustable cavities increasing sequentially from bottom to top.

[0012] In addition, in a preferred configuration, the bottom of each vertical push block is provided with a vertical push inclined surface and a vertical push flat surface, the end of each vertical push plate facing the support frame is provided with a vertical push inclined surface corresponding to the vertical push inclined surface, and the top of each vertical push plate is provided with a vertical push flat surface corresponding to the vertical push flat surface.

[0013] In addition, in a preferred structure, each of the vertical push plates is provided with multiple vertical push blocks, the height of the vertical push plates increases sequentially from bottom to top, the sum of the heights of the vertical push plates and the vertical push blocks is the same as the height of their corresponding adjusting vertical cavity, and the end of the vertical push plate facing the heating frame retracts sequentially from bottom to top.

[0014] In addition, a preferred structure is that the ends of the insert plates are all provided with chamfers, and the chamfers are adapted to the curvature of the edges and corners of the ceramic sheet.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] refer to Figure 1-2 A support frame 2 is fixed inside the sintering chamber 12 of the vacuum sintering machine 1. An openable door 11 is provided on one side of the sintering chamber 12. A heating ring 121 is installed inside the sintering chamber 12, and the heat generated by the heating ring 121 can sinter the ceramic sheet 13. These structures provide the necessary basic environment for the sintering of the ceramic sheet 13, and since this is existing technology, it will not be described in detail further.

[0020] See Figure 3-11 The top of the support frame 2 is fixed with multiple guide rails 21. The bottom of the firing rack 3 is provided with guide grooves 31 corresponding to the positions of the guide rails 21. This matching design allows the firing rack 3 to be inserted horizontally above the support frame 2 along the guide rails 21. The guide rails 21 and guide grooves 31 are existing technologies, so they will not be described in detail.

[0021] It is worth noting that the firing support 3 is moved by an external conveying mechanism. The method of moving the firing support 3 is existing technology, so it will not be described in detail.

[0022] A middle plate 35 is fixed in the middle of the firing support 3 to support the multiple firing layers on the firing support 3. In order to avoid structural collision, an anti-interference cavity 34 is provided on the firing support 3 at the position corresponding to the support frame 2, so as to ensure that the firing support 3 is more stable during movement.

[0023] See Figure 4-10 The movable seat 5 is located outside the cavity 33 on the firing rack 3. In the initial state, the movable rack 4 and the cavity 33 are aligned. The user can stack ceramic pieces 13 in the space formed by the movable rack 4 and the cavity 33, and the number of stacked ceramic pieces 13 is adapted to the number of ceramic grooves 32.

[0024] Among them, a fixed upright 24 is provided on the end of the support frame 2 facing the heating frame 3, and multiple horizontal push plates 241 are fixed on the fixed upright 24. The horizontal push plates 241 are provided with horizontal push slopes 242. A horizontal push plate 53 is provided on the outer side of the movable seat 5, and a horizontal push slope 531 is provided on the horizontal push plate 53.

[0025] When the sintering support 3 is pushed into the sintering chamber 12, the horizontal pushing inclined surface 242 contacts and presses against the horizontal receiving inclined surface 531. Through this inclined surface transmission, the movable seat 5 is pushed inward. At this time, the insert plate 543 fixed on the vertical receiving block 54 will smoothly enter the gap between the stacked ceramic sheets 13. The end of the insert plate 543 is chamfered, and the chamfer is adapted to the corner radius of the ceramic sheet 13, which makes it easier for the insert plate 543 to be inserted under the ceramic sheet 13, while avoiding damage to the ceramic sheet 13. Since the insert plate 543 is thin and the spacing of the sintering layers is designed to allow for the insertion space of the insert plate 543, the lifting of the ceramic sheet 13 caused by the thickness of the insert plate 543 is negligible.

[0026] See Figure 11-12 Multiple vertical push plates 25 are fixed on both sides of the support frame 2. Multiple adjusting vertical cavities 52 are divided on the movable seat 5 by multiple fixing blocks 51. A vertical push block 54 is located within the adjusting vertical cavity 52 and can move vertically. A vertical push inclined surface 541 and a vertical push flat surface 542 are provided at the bottom of the vertical push block 54. Correspondingly, vertical push inclined surfaces 251 and vertical push flat surfaces 252 are provided on the vertical push plates 25.

[0027] As the firing rack 3 continues to move inward, the vertical push plate 25 will come into contact with the vertical push block 54. The vertical push block 54 is lifted up by the vertical push slope 251, and then the ceramic sheet 13 can be lifted up by the insert plate 543.

[0028] Once the lifting is complete, the vertical pushing plane 252 will support the vertical pushing plane 542, stabilizing the vertical pushing block 54 at the top of the adjusting cavity 52, so that the insert plate 543 can stably lift the ceramic sheet 13 when the firing rack 3 continues to move.

[0029] To achieve layered conveying, the height of the vertical push plate 25 increases sequentially from bottom to top, and the end of the vertical push plate 25 facing the firing rack 3 retracts sequentially from bottom to top. At the same time, the height of the adjusting cavity 52 also increases sequentially from bottom to top. This staggered distribution design allows the insert plate 543 to move upward in segments. Through this movement, the stacked ceramic pieces 13 are sequentially lifted into the movable racks 4 of different firing layers.

[0030] Since the total height of the vertical push plate 25 and the vertical push block 54 is the same as the height of its corresponding adjusting cavity 52, it can be ensured that the vertical push plate 252 on the vertical push plate 25 can be stably pushed up when it comes into contact with the vertical push plate 542 on the vertical push block 54.

[0031] See Figure 4-13The firing rack 3 includes multiple firing layers, each layer having multiple ceramic grooves 32 for holding ceramic pieces 13. Above each firing layer are two movable racks 4, which are fixedly connected by guide plates 41. A guide cavity 351 is provided on the middle plate 35 corresponding to the guide plate 41. Through the adaptive arrangement between the guide plate 41 and the guide cavity 351, the movable racks 4 can be guided and moved.

[0032] After the ceramic sheet 13 is delivered to the movable rack 4 of each layer, the movable rack 4 is moved by the pusher 23. The movable rack 4 will transfer the ceramic sheet 13 above the corresponding ceramic groove 32 and make it fall into the groove, and the pressure frame 22 is adapted to the shape of the ceramic sheet 13.

[0033] As the firing support 3 moves, when the movable frame 4 is pushed to its outermost position by the pusher 23, the pressure frame 22 will move to the top of the ceramic tank 32. This will hold the ceramic sheet 13 in place, thus preventing warping or deformation of the ceramic sheet 13 during sintering and ensuring the stability of the production process.

[0034] It is worth noting that both the movable seat 5 and the vertical push block 54 are guided to move by the guide mechanism in the prior art, which is prior art and will not be described in detail here.

[0035] In this embodiment, during the sintering process of the ceramic sheets, the movable frame 4 and the through cavity 33 are initially aligned. At this time, the user only needs to stack multiple ceramic sheets 13 in the internal space formed by the movable frame 4 and the through cavity 33, then open the hatch 11, and then push the sintering support frame 3 into the sintering chamber 12 along the guide rail 21.

[0036] As the firing support 3 moves inward, the horizontal push plate 241 on the fixed upright 24 approaches and contacts the movable seat 5, causing the horizontal push slope 242 and the horizontal push-receiving slope 531 to come into contact and compress each other. Since the horizontal push plate 241 is fixed, the movement of the firing support 3 forces the movable seat 5 to move inward under the action of the slope transmission. When the movable seat 5 moves inward, the insert plate 543 on the vertical push-receiving block 54 also moves synchronously and inserts into the gap between the ceramic sheets 13 under the stacked ceramic sheets 13. It is worth noting that since the insert plate 543 is relatively thin, and the spacing of the firing layers is designed to allow for the insertion space of the insert plate 543, the lifting of the ceramic sheets 13 caused by the thickness of the insert plate 543 can be ignored.

[0037] As the firing rack 3 continues to move deeper, the vertical push slope 251 on the vertical push plate 25 contacts the vertical push slope 541 at the bottom of the vertical push block 54. With the relative sliding of the contact surfaces, the vertical push block 54 is pushed upwards by the vertical push plate 25. Since the height of the different vertical push plates 25 increases sequentially from bottom to top and retracts sequentially in the direction the firing rack 3 is pushed in, each insert plate 543 is lifted upwards in a segmented manner according to a preset sequence. This activity can lift the ceramic pieces 13 that were originally stacked together one by one and send them into the internal space of each corresponding movable rack 4. After the lifting is completed, the vertical push plane 252 supports the vertical push plane 542, stabilizing the vertical push block 54 at the top of the adjusting cavity 52, so that the insert plate 543 can stably lift the ceramic pieces 13.

[0038] Once all ceramic pieces 13 have been lifted into the corresponding movable frame 4, the firing support frame 3 continues to move inward. Since the pusher 23 is fixed above the support frame 2, the displacement of the firing support frame 3 causes the movable frame 4 to come into contact with the pusher 23. The pusher 23 prevents the movable frame 4 from continuing to move with the firing support frame 3, thereby forcing the movable frame 4 to undergo relative displacement along the guide cavity 351.

[0039] During the movement, the ceramic sheets 13 move synchronously with the movable frame 4 and fall into the corresponding ceramic grooves 32 in sequence. When the firing support frame 3 moves to the predetermined position, the ceramic sheets 13 in each firing layer fall into the ceramic grooves 32, and the pressure frame 22 moves to the top surface of the ceramic sheets 13 to achieve stable pressing of the ceramic sheets 13. This pressing method can avoid the problem of edge warping or deformation of the ceramic sheets 13 during high-temperature sintering. Finally, the user only needs to close the hatch 11 and start the heating ring 121 to complete the sintering operation.

[0040] After the ceramic sheet 13 is sintered, simply remove the firing support 3, then remove all the ceramic sheets 13, and manually reset the movable support 4 and movable seat 5.

[0041] In this invention, the vacuum sintering process of ceramic sheet 13 can be realized by the vacuum sintering machine 1. Through the cooperative arrangement of the support frame 2, the sintering frame 3, the movable frame 4 and the movable seat 5, the stacked ceramic sheet 13 can be transferred sequentially to each layer of ceramic tank 32 during the process of the sintering frame 3 being pushed into the sintering chamber 12, and the ceramic sheet 13 is pressed by the pressure frame 22 at the moving end.

[0042] This allows users to simply stack ceramic sheets 13 on the firing rack 3. When the firing rack 3 enters the vacuum sintering machine 1, it can automatically lay and press the ceramic sheets 13 on the multi-layer firing layer, thereby reducing the manual step of placing each sheet individually and improving the loading efficiency.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
