Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic product production, and particularly relates to an anti-crack conveying device during the drying process of high-moisture ceramic tile blanks. Background Technique

[0002] During the production process of ceramic products, the drying of the blank is a key step. Traditional drying methods usually adopt a fixed support method, such as pallet support. However, for high-moisture blanks, during the drying process, due to the evaporation of moisture and the shrinkage of the blank, the fixed support will cause the blank to be unable to move freely, resulting in cracks. This not only affects the product quality but also increases the production cost.

[0003] Currently, there are already some improved drying equipment on the market, but most of them still have the following problems:

[0004] Cracks caused by fixed support: High-moisture blanks shrink significantly during the drying process, and the fixed support cannot adapt to this change, easily causing cracks in the blank.

[0005] Improper material selection: Some equipment uses steel rollers for transmission, but during the microwave heating process, the steel rollers are easily affected, resulting in the equipment being unable to work properly.

[0006] Lack of flexibility: Existing equipment lacks flexibility in design and cannot achieve the free movement of the blank during the drying process, further increasing the risk of crack generation.

[0007] Roller deformation: Due to the thin rollers, they are easily deformed under the pressure of the ceramic tile blank, thus requiring additional support to maintain their stability. Content of the Utility Model

[0008] The technical problems solved by this implementation scheme: Solve the problem of cracks generated by the shrinkage of high-moisture blanks during the drying process, while reducing the density between the rollers, improving the supporting force of the rollers on the ceramic tile blank, and preventing the high-level ceramic tile blank from sinking and deforming due to the action of gravity.

[0009] The technical scheme adopted by this implementation scheme: An anti-crack conveying device during the drying process of high-moisture ceramic tile blanks, including a machine body, a transmission mechanism, ceramic rollers, and supporting wheels. The transmission mechanism is installed on the machine body and drives the ceramic rollers to rotate, so that the blank is in a non-fixed state during the drying process. The ceramic rollers are in contact with the blank and are connected to the machine body through a support frame and can rotate freely. The center distance between the ceramic rollers is controlled within 1 - 5 cm, and supporting wheels are arranged at the bottom to support the upper ceramic rollers, and the circumferences of the ceramic rollers and the supporting wheels are externally tangent.

[0010] Beneficial effects produced by this implementation scheme: Avoid cracks in the green body during the drying process due to fixed support, and improve product quality. Since the distance between the ceramic rollers is narrow, the diameter of the ceramic rollers is relatively thin, and the ceramic rollers are prevented from bending through the action of the support wheels.

[0011] Working principle adopted in this implementation scheme: Drive the ceramic rollers to rotate through the transmission mechanism, so that the green body is in a non-fixed state during the drying process, thus avoiding the generation of cracks.

The motor drives the gear to rotate through the transmission chain, and the gear is connected to the shaft of the ceramic roller through a keyway and fixed on the shaft of the ceramic roller, thus driving the ceramic roller to rotate.

[0018] In the preferred implementation case, the beneficial effects produced: Realize the automatic rotation of the ceramic rollers and improve the drying efficiency.

[0019] Adopted working principle: Drive the ceramic rollers to rotate by driving the transmission chain and the gear with the motor.

[0020] In the preferred implementation case, the technical problem to be solved: Reduce the pressure of the ceramic rollers on the green body.

[0022] In the preferred implementation case, the beneficial effects produced: Reduce the pressure of the ceramic rollers on the green body and avoid damage to the green body.

[0023] Adopted working principle: Reduce the pressure on the green body by setting a flexible cushion layer on the surface of the ceramic roller.

[0024] In the preferred implementation case, the technical problem to be solved: Achieve periodic contact and separation between the ceramic rollers and the green body.

[0025] In the preferred embodiment, the adopted technical solution is that the rotation and stop of the ceramic roller are controlled by a controller.

[0026] In the preferred embodiment, the beneficial effect produced is to achieve the periodic contact and separation between the ceramic roller and the green body, avoiding damage to the green body.

[0034] In the preferred embodiment, the beneficial effect produced is to adjust the position of the supporting wheel as needed to ensure the smooth rotation of the ceramic roller.
