Technical Field

[0001] This utility model belongs to the field of porcelain painting firing, and specifically relates to a porcelain painting firing clamping device. Background Technology

[0002] In porcelain painting production, the clamping operation during the firing process has a significant impact on the quality of the finished product and production efficiency. Porcelain paintings consist of porcelain plates and glaze. If the plates are not placed stably during firing, the porcelain plates are prone to deformation or displacement, or the glaze may run, seriously affecting the artistic effect and yield of the porcelain painting.

[0003] Currently, the most widely used porcelain painting firing clamping devices in the industry are frame structures. These devices have obvious defects when placing and removing porcelain paintings layer by layer. Because the frames are mostly fixed connections, the space adjustment between each layer is limited. The porcelain paintings need to be inserted from the side and fixed. When the operator places or removes the porcelain paintings, they may accidentally collide with the frame components, which not only increases the difficulty of operation but may also cause wear and tear on the edges of the porcelain paintings.

[0004] Therefore, we propose a porcelain painting firing clamping device to solve the above problems. Utility Model Content

[0005] In view of the fact that most of the porcelain painting firing clamping devices widely used in the industry are frame structures, which have obvious defects when the porcelain paintings are picked up and put down layer by layer, this utility model provides a porcelain painting firing clamping device.

[0006] The solution adopted by this utility model to solve its technical problem is: a porcelain painting firing clamping device, including a base, a support shaft, a limiting shaft and N sets of porcelain painting positioning units, wherein the bottom end of the support shaft is welded and fixed to one corner of the base.

[0007] The N sets of porcelain painting positioning units are arranged sequentially from top to bottom. Each porcelain painting positioning unit includes a rotating plate, a support plate, and a U-shaped limiting strip. One end of the rotating plate is rotatably mounted on the support shaft. Two placement seats for supporting the porcelain painting are welded and fixed to the top of the rotating plate and the top of the support plate.

[0008] A baffle strip for blocking the edge of the porcelain painting is welded and fixed to the top of the placement base. A U-shaped limiting strip is detachably installed on the top of the two placement bases through two connectors. The porcelain painting is clamped and positioned between the U-shaped limiting strip and the two baffle strips.

[0009] The support plate has a through hole in the middle, and the bottom end of the limiting shaft passes through N through holes in sequence and is detachably connected to the base.

[0010] Preferably, the placement seat has a recessed cavity inside, with openings at both ends.

[0011] Preferably, the placement base has multiple insertion holes arranged from left to right.

[0012] Preferably, the connector is a plug that is welded and fixed to the bottom of the U-shaped limiting strip, and the bottom end of the plug is inserted into the corresponding socket.

[0013] Preferably, the top of the base is provided with a threaded groove, and the bottom end of the limiting shaft is provided with an external thread, so that the bottom end of the limiting shaft is threadedly connected in the threaded groove.

[0014] Preferably, a lifting ring one is welded and fixed to the top of the support shaft, and a lifting ring two is welded and fixed to the top of the limiting shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model connects the rotating plate to the support shaft in a rotating manner. When placing the porcelain painting, the limiting shaft can be pulled out and the rotating plate can be flipped outward to completely open the porcelain painting placement area. This open operating space makes the process of taking and placing the porcelain painting more intuitive and convenient, completely avoids the risk of collision with the frame components, and significantly reduces the difficulty of operation and the probability of wear on the edges of the porcelain painting.

[0017] 2. This utility model adopts a detachable structure of U-shaped limiting strip and insertion hole, combined with multi-position insertion hole design, which can flexibly adapt to the fixing needs of porcelain paintings of different sizes. In addition, the U-shaped limiting strip and two stop strips form a stable clamping space to ensure that the porcelain painting will not shift during the firing process.

[0018] 3. This utility model ensures the stability of the multi-layer ceramic painting positioning unit during the overall loading and unloading process by passing through multiple through holes at the bottom end of the limiting shaft and connecting it with the threaded groove.

[0019] 4. The placement base of this utility model has a concave cavity inside, with open ends, which can reduce the contact area with the bottom of the porcelain painting. In addition, the concave cavity inside the placement base forms a bottom ventilation channel, which allows the hot gas generated during the firing process to flow smoothly, avoiding local airflow obstruction that may cause firing defects in the porcelain painting, and thus improving the overall firing quality of the porcelain painting.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1-2 This utility model provides a technical solution for a porcelain painting firing clamping device:

[0025] Example 1:

[0026] according to Figure 1 and Figure 2 As shown, it includes a base 1, a support shaft 21, a limiting shaft 31, and N sets of porcelain painting positioning units. The bottom end of the support shaft 21 is welded and fixed to one corner of the base 1. The support shaft 21 has N sets of retaining rings 44 arranged from top to bottom, and there are two retaining rings 44 in each set.

[0027] N sets of porcelain painting positioning units are arranged sequentially from top to bottom. Each porcelain painting positioning unit includes a rotating plate 41, a support plate 42, and a U-shaped limiting strip 46. One end of the rotating plate 41 has a through hole through which a support shaft 21 passes. The rotating plate 41 is located between two upper and lower retaining rings 44. The upper and lower retaining rings 44 limit the rotation of the rotating plate 41, allowing the rotating plate 41 to rotate around the support shaft 21. Two placement seats 43 for supporting the porcelain painting are welded and fixed to the top of the rotating plate 41 and the top of the support plate 42.

[0028] The placement base 43 has a recessed cavity inside, with openings at both ends, which reduces the contact area with the bottom of the porcelain painting. The recessed cavity inside the placement base 43 forms a bottom ventilation channel, allowing the hot gas generated during firing to flow smoothly. This avoids local airflow obstruction that could cause firing defects in the porcelain painting, and helps improve the overall firing quality of the porcelain painting.

[0029] A baffle 45 for blocking the edge of the porcelain painting is welded and fixed to the top of the placement base 43. Multiple insertion holes 48 are opened on the placement base 43 from left to right. A U-shaped limiting strip 46 is detachably installed on the top of the two placement bases 43 through two connectors. The connectors are plugs 47 welded and fixed to the bottom of the U-shaped limiting strip 46. The bottom end of the plug 47 is inserted into the corresponding insertion hole 48. By adopting the detachable matching structure of the U-shaped limiting strip 46 and the insertion hole 48, and with the multi-position insertion hole 48 design, it can flexibly adapt to the fixing needs of porcelain paintings of different sizes. The porcelain painting is clamped and positioned between the U-shaped limiting strip 46 and the two baffles 45 to ensure that the porcelain painting will not shift during the firing process.

[0030] The support plate 42 has a through hole in the middle, the base 1 has a threaded groove on the top, and the bottom of the limiting shaft 31 has an external thread 33. The bottom of the limiting shaft 31 passes through N through holes in sequence and is threadedly connected to the threaded groove to ensure the stability of the multi-layer ceramic painting positioning unit during the overall picking and placing process.

[0031] A lifting ring 22 is welded and fixed to the top of the support shaft 21, and a lifting ring 32 is welded and fixed to the top of the limiting shaft 31, so that the user can use the lifting ring 22 and the lifting ring 32 to pick up and put down the device.

[0032] The entire device is made of 310S stainless steel, which has excellent high temperature resistance and oxidation resistance. It can maintain structural stability in the high temperature environment of firing, and is not easily deformed or damaged, thus extending the service life of the device.

[0033] In practical use, the ceramic painting firing clamping device of this utility model first flips the rotating plate 41 outward to completely open the ceramic painting placement area. Then, the ceramic painting is placed flat on the top of the two placement seats 43, and one side of the ceramic painting contacts the two baffles 45. Then, the insertion hole 48 that matches the width of the ceramic painting is selected, and the insertion block 47 at the bottom of the U-shaped limiting strip 46 is inserted into the corresponding insertion hole 48 of the two placement seats 43 to position the ceramic painting and ensure that the ceramic painting will not shift during the firing process. After that, the rotating plate 41 is rotated in the opposite direction to reset the rotating plate 41 and the support plate 42.

[0034] Repeat the above steps to place and fix the porcelain painting on each layer of the porcelain painting positioning unit. Then, the bottom end of the limiting shaft 31 is threaded through multiple through holes and connected to the threaded groove to ensure the stability of the multi-layer porcelain painting positioning unit during the overall lifting and placing process. Finally, the entire unit is lifted and placed into the kiln smoothly through the lifting ring 22 and lifting ring 32.
