Description

Vertical turntable automatic glaze dipping device

technical field

The invention relates to daily-use ceramic production equipment, in particular to an automatic glazing device for daily-use ceramics.

Background technique

In the production of daily-use ceramics in the past, due to the difference in the performance of raw materials or the limitation of the shape of various products, the glazing process of various ceramic manufacturers can only be performed by manual glazing. The production efficiency of manual glazing is low. During the glazing process, fingers touch the green body, leaving fingerprints on the green body after glazing, which affects the glazing quality of the green body. In addition, since there are various chemical materials added to the glaze water, these chemical materials have a corrosive effect on the human body, and long-term manual glazing is harmful to the human body.

In order to improve production efficiency, improve product quality, improve the production environment for workers, and reduce costs, technicians are constantly improving the production technology and production equipment of daily-use ceramics. In the existing ceramic production technology, the technical literature on the ceramic glazing process includes:

1. The patent document [publication number: CN202373397U] discloses a "glazing device for the head of a disc-shaped suspended porcelain insulator porcelain clay blank", which includes a rotatable station platform on which an inverted porcelain clay blank is placed, The outer peripheral surface dipping device of the head for distributing glaze on the outer peripheral surface of the porcelain clay blank, the head inner hole glaze injecting device for distributing glaze on the inner surface of the porcelain clay blank, and the electric control cabinet. The device realizes the continuous completion of the porcelain clay blank step by step by placing the inversion of the "∩"-shaped head of the porcelain clay blank on the rotary platform station and rotating 360° with the help of electrical control. Glazing process for the peripheral surface of the head. The device has a high degree of automation, but is complex in structure and high in cost, and can only achieve glazing on a certain part of the blank.

2. The patent document [publication number: CN2647444] discloses a "glazing machine". The glazing machine achieves glazing by combining the reciprocating mechanism and the corner mechanism with the spray gun mechanism and using the motor controlled by the controller as the power source. The spray gun mechanism is arranged on the frame, and the workpiece clamping mechanism is also arranged on the frame. wait. The glazing machine is suitable for glazing treatment on the outer surface of cylindrical workpieces with corrugated rings, and is not suitable for glazing treatment of special-shaped workpieces.

3. The patent document [publication number: CN1090834] discloses a kind of "partial surface glazing of ceramic products". Cooling of the molten region achieves localized surface glazing by limiting thermal stresses developed in the article proximate to the molten region to less than the fracture stress of the ceramic material on the surface of the article. The utility model is mainly used for repairing glaze defects and as decoration. The energy consumption of glazing in this way is huge, and it is not suitable for a mass production process.

4. The patent document [publication number: CN202246453U] discloses "a glazing device", which is mainly composed of three parts: a glazing tank, a pressure-stabilizing tank, and a glazing pump. Add the glaze to the glaze adding tank first, send the glaze into the pressure-stabilizing tank through the glaze pump, and then apply the glaze on the surface of the rubber roller through the discharge valve to realize the glaze process. The device can realize a relatively uniform glazing process, but this process is too complicated and the production efficiency is low, and the thickness of the glazing layer is also changed by the wear and purity of the rubber roller, resulting in unstable glazing quality.

5. Patent literature [publication number: CN202422887U] discloses a "line post type insulator glazing device", which includes a support frame, a motor and a chuck for fixing the green body, the motor is fixed on the support frame; the motor, the chuck Rotate coaxially with the embryo body. The device can be used in the glazing process in the production process of electric porcelain insulators. The chuck-type fixing method increases the contact area between the embryo body and the glazing device, reduces the area of one-time glazing, and affects production efficiency.

6. The patent document [publication number: CN1223926] discloses a "rotary glazing machine especially for ceramic tiles". Unhindered contact rolls on the upper surface of the tile to transfer the glaze to the tile, while the second roller rotates in the opposite direction to the first roller. This device is suitable for the glazing process of tiles, but it has very strict requirements on the rheological dynamic parameters of the glaze water. If the glaze water changes or the composition of the glaze water is not uniform enough, it will easily cause the thickness of the glaze layer to be inconsistent, which will directly affect the yield.

7. Patent literature [publication number is CN203187583U] In the utility device patent titled "Automatic Glazing Device for Daily Use Ceramics", there are glaze suction holes on the wall of the glaze storage cylinder, so that the glaze water can be sucked into the glaze storage cylinder and used as a glaze for the bottom of the bowl In the production process, it was found that when the suction cup mechanism sucks the bowl body and swings to the glaze pool for glazing, the time for the bottom of the bowl to contact the glaze water is relatively longer than the time for the bowl surface to contact the glaze water. For some bodies with strong water absorption, use this If the glaze is glazed by this method, the thickness of the glaze layer on the bottom of the bowl is obviously greater than that on the surface of the bowl, and the glaze on the green body is unqualified.

To sum up, the existing existing glazing devices mainly have defects such as low efficiency, poor glazing quality, complex structure, excessive labor intensity of workers, and the degree of automation needs to be improved.

Among them, A is the loading station, B is the unloading station, and the arrow indicates the production flow.

Detailed ways

As shown in Figures 1 and 2, firstly, the bowl blank 6 is transferred to the A station by the feeding bracket 12 and the feeding conveyor belt 13, and the frequency conversion motor 1 drives the small pulley 14 to rotate, and the rotation of the small pulley 14 is transmitted to the The big pulley 3, the big pulley 3 drives the vertical turntable 15 to shift to the A station, and then the feeding suction cup 10 moves the unglazed bowl blank 6 on the feeding conveyor belt 13 to the L-shaped bowl support 5, and completes the process. During the feeding process of the bowl blank 6, the bottom surface of the L-shaped bowl support 5 is always parallel to the ground due to the effect of gravity, so as to ensure that the bowl blank 6 does not fall from the L-shaped bowl support 5.

Then the frequency conversion motor 1 drives the vertical turntable 15 through the small pulley 14, the belt 2 and the large pulley 3 to rotate, and brings the L-shaped bowl support 5 and the bowl blank 6 into the glaze pool 11 to glaze the bowl blank 6 and wait for the glaze to be applied. After the completion, the vertical turntable 15 continues to rotate to bring the L-shaped bowl holder 5 and the bowl blank 6 out of the glaze pool 11. During the rotation of the vertical turntable 15, the glaze water staying on the L-shaped bowl holder 5 will fall off under the action of gravity. into the glaze pool 11 to avoid wasting glaze water. When the vertical turntable 15 is turned to the B station, the unloading suction cup 9 moves to move the bowl blank 6 to the unloading conveyor belt 7, and the unloading conveyor belt 7 transmits the bowl blank 6 to the bottom. One process completes the entire glazing process. When the vertical turntable 15 is indexed to station A again, the aforementioned process is repeated for the next glazing cycle, and the cycle reciprocates.
