A firing support to prevent deformation of the rim of a ceramic pot

Abstract

This utility model relates to the field of ceramic product firing technology, and more particularly to a firing support for preventing deformation of the rim of a ceramic pot. It includes a base, supports, connecting seats, connecting plates, rotating shafts, stabilizing blocks, and movable frames. Supports are fixedly connected to the top left and right sides of the base, and connecting seats are slidably connected between two supports. A connecting plate is fixedly connected to the bottom center of the connecting seats. Four rotating shafts are fixedly connected in a circular array around the center of the bottom of the connecting plate. A stabilizing block is rotatably connected to each rotating shaft, and a sliding groove is formed on the inner side of each stabilizing block, within which a movable frame is slidably connected. This utility model drives the movable frame to move axially via a threaded rod at the bottom of the connecting seat. The movable frame slides within the sliding groove of the stabilizing block, pushing the stabilizing block to swing outward synchronously around the rotating shaft. This ensures that the inner edges of multiple stabilizing blocks evenly conform to the bottom surface of the rim of the ceramic pot, providing circumferential support and effectively preventing the rim from collapsing or shrinking due to softening during high-temperature firing.

Description

Technical Field

[0001] This utility model relates to the field of ceramic product firing technology, and in particular to a firing support to prevent deformation of the mouth of a ceramic pot. Background Technology

[0002] Ceramic pots, as a widely used traditional cooking utensil, are favored by consumers for their excellent heat retention, uniform heat conduction, and unique cooking flavor. During production, ceramic pots undergo a high-temperature firing process to densify the body and melt the glaze, resulting in good mechanical strength and surface smoothness. Firing is a crucial step in the forming of ceramic products, directly determining the final quality and performance. However, at high temperatures, the ceramic material temporarily softens, and its own weight can cause deformation in structurally weak areas. The rim of the pot, due to its suspended annular structure, lacks effective support and is prone to collapsing or shrinking inwards under gravity, leading to an out-of-round rim, dimensional deviations, and severely affecting the product's appearance and the seal with the lid.

[0003] Currently, in the ceramic firing process, shims, pads, or simple support frames are commonly used to support ceramic products. However, these devices mostly only function at the bottom or lower side walls of the pot, failing to provide targeted support for the rim area. Some manufacturers have attempted to use refractory clay for temporary fixing or custom-made molds, but the former is cumbersome and inconsistent, while the latter is costly and lacks versatility. Furthermore, traditional support methods lack stability, making them prone to tipping or displacement during kiln operation, posing safety hazards. They also lack cushioning capabilities, failing to cope with vibrations in the firing environment and further exacerbating the risk of deformation.

[0004] Therefore, it is necessary to design a firing support to prevent deformation of the rim of the ceramic pot, in order to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing ceramic firing processes, which are prone to collapse or shrinkage deformation of the rim of ceramic pots due to the lack of effective support at the rim, this utility model provides a firing support to prevent deformation of the rim of ceramic pots.

[0006] The technical solution is as follows: A firing support for preventing deformation of the rim of a ceramic pot includes a base, legs, brackets, a connecting seat, and fixing screws. The base has legs symmetrically fixedly connected to both the front and rear sides of its bottom, and brackets fixedly connected to both the left and right sides of its top. A connecting seat is slidably connected between the two brackets. Fixing screws pass through both sides of the connecting seat and are threadedly connected to the brackets. The support also includes a connecting plate, rotating shafts, stabilizing blocks, a movable frame, a threaded rod, and a knob. A connecting plate is fixedly connected to the center of the bottom of the connecting seat. Four rotating shafts are fixedly connected in a circular array around the center of the bottom of the connecting plate. A stabilizing block is rotatably connected to each rotating shaft. A sliding groove is opened on the inner side of each stabilizing block, and a movable frame is slidably connected within the groove. The threaded rod passes through the connecting seat and the connecting plate and is fixedly connected to the movable frame. A knob is fixedly connected to the top of the threaded rod.

[0007] To further explain, it also includes support rods, connecting rings, guide rods, anti-tipping rings, and elastic elements. Four support rods are fixedly connected in a circular array around the center of the top of the base. The top of the four support rods are all fixedly connected to the connecting ring. Four guide rods are arranged in a circular array around the outer periphery of the connecting ring. The guide rods are slidably connected to the connecting ring. The top of the four guide rods is fixedly connected to the anti-tipping ring. An elastic element is connected between the anti-tipping ring and the connecting ring. The elastic element is sleeved on the guide rod.

[0008] To further explain, it also includes a placement frame, with a placement frame located in the center of the top of the base.

[0009] To further explain, the bracket has multiple adjustment screw holes.

[0010] To further explain, the anti-tipping ring is circular, and its inner diameter is larger than the inner diameter of the ceramic pot to be fired.

[0011] To further clarify, both the stabilizing block and the anti-tipping ring are made of high-temperature resistant materials.

[0012] The beneficial effects are as follows: 1. This utility model drives the movable frame to move axially through the threaded rod at the bottom of the connecting seat. The movable frame slides in the inner groove of the stabilizing block, pushing the stabilizing block to swing outward synchronously around the rotation axis, so that the inner edges of multiple stabilizing blocks are evenly attached to the bottom surface of the ceramic pot mouth, achieving circumferential support and effectively preventing the mouth from collapsing or shrinking and deforming due to softening during high-temperature firing.

[0013] 2. This utility model improves the overall stability of the support by setting support rods in a ring array at the top of the base and connecting them with connecting rings, and then setting guide rods and anti-tipping rings that are slidably connected on the outer periphery of the connecting rings. An elastic element sleeved on the guide rods is set between the anti-tipping rings and the connecting rings. During the firing process, it can effectively absorb the vibration of the kiln and prevent the support from tipping over or shifting, thus ensuring the safety and stability of the firing operation.

[0014] 3. This utility model achieves the effect of adjusting the height of the connecting seat by sliding the connecting seat between two brackets and locking it with the adjusting screw hole on the bracket by fixing screw. With the help of the knob driving the threaded rod to drive the stabilizing block to extend and retract radially, the bracket can adapt to ceramic pots of different heights and diameters, thus improving the versatility and flexibility of the device.

Detailed Implementation

[0021] Example: A firing support to prevent deformation of the rim of a ceramic pot, such as... Figure 1 , Figure 4 and Figure 5As shown, the system includes a base 1, legs 2, brackets 3, connecting seats 4, and fixing screws 5. The legs 2 are symmetrically connected to the bottom front and rear sides of the base 1 via screws. The brackets 3 are connected to the top left and right sides of the base 1 via screws. Each bracket 3 has multiple adjusting screw holes. A connecting seat 4 is slidably connected between two brackets 3. Fixing screws 5 pass through the left and right sides of the connecting seat 4 and are threadedly connected to the brackets 3. The system also includes a connecting plate 11, a rotating shaft 12, a stabilizing block 13, a movable frame 15, a threaded rod 16, a knob 17, and a placement frame 18. 4. A connecting plate 11 is connected to the bottom center by screws. Four rotating shafts 12 are connected to the bottom of the connecting plate 11 in a circular array with the center as the center by screws. Each rotating shaft 12 is rotatably connected to a stabilizing block 13. Each stabilizing block 13 has a sliding groove 14 on its inner side. A movable frame 15 is slidably connected in the sliding groove 14. A threaded rod 16 passes through the connecting seat 4 and the connecting plate 11 and is fixedly connected to the movable frame 15. A knob 17 is connected to the top of the threaded rod 16 by screws. A placement frame 18 is provided in the middle of the top of the base 1. The stabilizing block 13 and the anti-tipping ring 9 are both made of high temperature resistant materials, such as alumina.

[0022] like Figure 2 and Figure 3 As shown, it also includes support rods 6, connecting rings 7, guide rods 8, anti-tipping rings 9, and elastic elements 10. Four support rods 6 are connected to the top of the base 1 in a circular array with the center as the center by screws. The top of the four support rods 6 are connected to the connecting ring 7 by screws. Four guide rods 8 are arranged in a circular array on the outer periphery of the connecting ring 7. The guide rods 8 are slidably connected to the connecting ring 7. The top of the four guide rods 8 are connected to the anti-tipping rings 9 by screws. The anti-tipping rings 9 are circular rings with an inner diameter larger than the inner diameter of the ceramic pot to be fired. An elastic element 10 is connected between the anti-tipping rings 9 and the connecting rings 7. The elastic element 10 is sleeved on the guide rods 8.

[0023] When this device is needed, the operator first places the ceramic pot to be fired stably in the placement frame 18 on the top of the base 1, ensuring that the center of the pot is aligned with the support 3. At this time, the support legs 2 on the front and rear sides of the bottom of the base 1 provide stable support. According to the specific height of the ceramic pot, the operator manually rotates the fixing screws 5 on both sides of the connecting seat 4 to loosen the locking force between it and the support 3, so that the connecting seat 4 slides up and down along the support 3 to a position that matches the height of the opening of the ceramic pot. Then, the fixing screws 5 are tightened again to fix it firmly, thus completing the height adjustment and initial positioning.

[0024] After adjustment, the operator manually turns knob 17 to rotate the threaded rod 16 located at the center of connecting seat 4. Since the threaded rod 16 passes through connecting seat 4 and connecting plate 11 and is fixedly connected to movable frame 15, its rotational motion is converted into axial movement of movable frame 15. Movable frame 15 slides in the groove 14 inside the stabilizing block 13, pushing the four stabilizing blocks 13 to swing outward synchronously around their respective rotation axes 12, so that the inner edge of the stabilizing block 13 is evenly attached to and supported on the bottom surface of the ceramic pot opening, realizing circumferential limiting and support of the opening, preventing it from collapsing or shrinking and deforming at high temperature.

[0025] During the firing process, the anti-tipping ring 9 above the connecting ring 7 connected to the support rod 6 at the top of the base 1 remains stable under the buffering effect of the elastic element 10. The sliding fit of the guide rod 8 on the connecting ring 7 works in conjunction with the elastic element 10 to absorb slight vibrations in the kiln, preventing the support 3 from shaking or tipping over as a whole, thus ensuring the stability of the firing process. After firing, the operator rotates the knob 17 in the opposite direction to make the stabilizing block 13 retract inward and detach from the mouth of the ceramic pot. Then, the fixing screw 5 is loosened, and the fired ceramic pot can be taken out from the placement frame 18, completing a complete work cycle.
