Description

Technical Field

[0001] The utility model relates to the field of sanitary ware, in particular to a device for translating the edge of a flat burning basin. Background Art

[0002] Ceramic wash basins are divided into thin-edge basins and medium-edge basins in terms of appearance. It is generally believed that basins with a basin panel thickness of less than 20 mm are thin-edge basins, and basins with a basin panel thickness of more than 20 mm are medium-edge basins. Thin-edge basins are lighter and look simpler, while medium-edge basins have thicker edges and look more plump.

[0003] To most people, the structure of a basin is very simple, and the kiln firing is not complicated. In fact, the most difficult product to fire in the sanitary ceramics industry is the thin-edged basin. At present, all ceramic factories use the kiln column to support the kiln plate, put the basin liner into the opening of the kiln plate, and then place the basin panel steadily on the kiln plate for firing.

[0004] Among the current ceramic products, the narrow edge of the flat-fired thin-edge basin or medium-edge basin attached to the kiln plate is always more than 5 cm. The reason is: if the narrow edge of the basin is less than 5 cm, when the basin shrinks, the narrow edge of the basin will be separated from the kiln plate due to shrinkage, and the narrow edge of the basin will sag during high-temperature calcination due to lack of support. For users, the narrower the basin edge, the better.

[0005] Small bathrooms with an actual usable area of ​​less than 2 square meters are generally only suitable for basins with a length of less than 800 mm. Consumers hope that the basin is as large as possible, and would like to use the 800 mm length to design two basins, one large basin that is always kept clean for washing face and clothes, and the other small basin for spitting out toothpaste and saliva when brushing teeth, etc. The hygiene standard can be appropriately lowered to reduce the difficulty of daily basin cleaning.

[0006] As a manufacturer, even if the narrow side of the basin is 50 mm wide, the current production process is very difficult. The main problems are: the narrow side of the basin is not straight, the basin corners are upturned, and the back of the basin corners are cracked. These product quality problems have not been solved well, and the qualified rate of finished products is very low. We are worried about this every day. If we still want to make the narrow side of the basin narrower and realize the double basin design, it is absolutely impossible.

[0007] We have carefully analyzed the causes of the problems existing in flat-fired basins in the current sanitary ceramics industry:

[0008] The narrow edge of the basin is not straight: The current method of firing flat basins in the ceramic industry is to fire the basin panel against the kiln plate and the basin liner suspended in the air. The shrinkage ratio of the basin body before and after calcination is generally 1:1.14. In order to reduce the friction of the basin panel against the kiln plate when the basin panel shrinks, aluminum powder will be evenly coated on the kiln plate before climbing the kiln. Because the basin liner is calcined in the air, after calcination and shrinkage, the distance between the upper edge of the basin liner and the opening of the kiln plate varies greatly in each section. The weight of the basin liner makes the friction of the narrow edge of the basin on the kiln plate in different sections different. The shrinkage is small when the friction is large, and the shrinkage is large when the friction is small. Therefore, the narrow edge of the basin is not straight.

[0009] Distortion of basin panel: When the clay of the basin shrinks after high temperature, the narrow edge of the basin is lighter in weight, the friction force per unit area is smaller, and the distance to the basin is closer, so the gravity of the basin falling down has a more obvious effect on the narrow edge of the basin. When the narrow edge of the basin is displaced more on the horizontal plane of the kiln plate, the places with greater friction on the narrow edge of the basin will turn up due to the difficulty of shrinking, thus causing the basin panel to be distorted.

[0010] The narrow edge of the basin cannot be narrowed to the extreme: For users, the narrower the narrow edge of the basin on the front side of the basin panel close to the standing person, the more convenient it is, and the closer the arm is, the less effort it will take. The current narrow edge width in the industry is 50 mm. If it is too narrow, the narrow edge of the basin will have no kiln plate to support it when the blank shrinks, and the narrow edge of the basin will naturally sag and become waste. In fact, the current 50 mm narrow edge width of the basin is indeed a bit too wide, and it will feel very tiring if you wash things for a long time. As for assuming that you want to make a double basin on a basin with a total length of only 800 mm, and the narrow edge of the basin on the side of the basin cannot be narrowed to the extreme, the width of the basin of the double basin is not ideal.

[0011] Climbing and unloading the kiln is very troublesome: the clay of the thin-edged basin is very fragile, and the basin panel will break if you are not careful when carrying it. Especially when climbing the kiln, one person must lift the clay close to the top of the kiln hole with great force, and then another person reaches under the kiln hole with both hands to catch the basin, and then gently put the clay on the kiln board, which is both laborious and prone to coordination errors; if a robot is used to climb the kiln, it is not only uneconomical, but also easy to damage the glaze.

[0012] Is there any way to solve the above problems in the production process of thin-edged basins? We have made the following discussion. Utility Model Content

[0013] The utility model provides a device for translating the edge of a flat-fired basin. According to the principle of the action and reaction force of friction, a movable supporting plate which can translate is designed under the narrow edge of the basin. When the clay blank of the basin shrinks during high-temperature calcination, the distance generated by the shrinkage of the blank is realized by the horizontal displacement of the movable supporting plate, and the movable supporting plate supports the narrow edge of the basin for frictionless movement. When the entire edge of the narrow edge of the basin shrinks, the movable supporting plate is supported by the movable supporting plate and realizes overall synchronous displacement, so that no moving surface is generated between the narrow edge of the basin and the movable supporting plate, and the friction between the narrow edge of the basin and the movable supporting plate is eliminated, thereby solving the problems of the narrow edge of the basin being not straight, the panel corner being warped, the panel of the basin being twisted, the narrow edge of the basin being unable to be narrowed to the limit, and the trouble of climbing the kiln and unloading porcelain generated during the calcination of the thin-edge basin.

[0014] The above-mentioned purpose of the utility model is achieved through the following technical solutions:

[0015] In order to facilitate the detailed description of the calcination process of flat-fired pots in the patent document, we draw the kiln plate and the clay body of the pot before climbing the kiln in sections for illustration:

[0016] The kiln plate part includes: movable support plate, support plate horizontal surface, movable platform, roller, kiln hearth, kiln plate and kiln plate horizontal surface.

[0017] The clay body of the basin includes: basin panel, basin liner corners, panel corners, basin narrow edge, and basin liner.

[0018] Since the narrow edge of the basin has weak deformation resistance, it is easy for the stress points with greater friction to be blocked from shrinking freely and cannot shrink freely, causing the entire narrow edge of the basin to be crooked and twisted. Based on the principle of action and reaction of friction, we designed a movable support plate that can move horizontally under the narrow edge of the basin. When the clay blank of the basin shrinks during high-temperature calcination, the distance generated by the shrinkage of the blank is achieved by the horizontal displacement of the movable support plate, and the movable support plate supports the narrow edge of the basin for frictionless movement. The entire edge of the narrow edge of the basin is supported by the movable support plate when it shrinks and achieves overall synchronous displacement, so that no moving surface is generated between the narrow edge of the basin and the movable support plate, eliminating the friction between the narrow edge of the basin and the movable support plate, thereby solving the problems of the crooked narrow edge of the basin, the upturned panel corners, the twisted basin panel, the inability to narrow the narrow edge of the basin, and the trouble of climbing the kiln and unloading porcelain caused by the calcination of thin-edged basins.

[0019] Optionally, the flat-fired basin-type supporting and translating device may be adapted to flat-fired kiln designs of single and double basins.

[0020] Optionally, the movable support plate may be designed to support only the narrow side of the basin, or may be designed to support other sides to achieve synchronous displacement.

[0021] Optionally, the design length of the movable support plate is not limited, and it can be designed to support the entire edge or only support a local portion that is subject to major deformation.

[0022] Optionally, there are multiple options for the structural method of forming smooth displacement of the movable support plate, including a translation bracket, a temperature-resistant ball, a temperature-resistant roller, a temperature-resistant bearing support, a suspended bracket, a smooth trolley, etc.

[0023] Optionally, the movable support plate is designed either inside or outside the frame of the kiln plate, or the movable support plate is directly used as the frame of the kiln plate.

[0024] Optionally, the movable support plate is designed to be in a straight bar shape or a special shape with a certain curvature.

[0025] Optionally, the movable support plate can be structured in a stepped structure on the kiln plate, or can be a movable device that relies on the lower kiln furniture or kiln floor as a support for a separately designed movable support plate.

[0026] Optionally, the movable support plate may be made of high temperature resistant materials such as mullite, silicon carbide, silicon nitride, etc.

[0027] Compared with the product quality of the existing flat calcining basin kiln furniture structure in the industry, the utility model of the flat calcining basin side support translation device has the following advantages:

[0028] 1. Ensure the straightness and regularity of the narrow edge of the basin. For flat-fired basins, the difficulty lies in the difficulty of firing the narrow edge of the basin straight and flat. Generally speaking, the width of the narrow edge of the basin is 5-6 cm, especially for thin-edge basins, it is extremely difficult to fire straight and flat. Because of this problem that cannot be fundamentally solved, the industry stipulates that the straightness of the porcelain is allowed to have an error of 3 mm. In fact, the error of 3 mm is already very ugly for the appearance of the product, giving people a very unrefined feeling. The reason for the uneven narrow edge of the basin is: the basin is an asymmetric cavity, the front is relatively flat, and the back is close to vertical. When shrinking, the shrinkage force of the center of the basin and the sides of the basin is very different; in addition, when shrinking, the friction between the narrow edge of the basin and the kiln plate will be different at each part due to the difference in gravity and structural force. The reason for the uneven narrow edge of the basin is: because the narrow edge of the basin is relatively narrow, the mass of the blank is light, and when the shrinkage displacement distance of the narrow edge of the basin is different, the upward tilt of the narrow edge of the basin is also different. The utility model of the flat-fired basin edge support translation device supports the easily deformed narrow edge of the entire basin with a movable support plate, and the movable support plate is horizontally displaced to realize frictionless movement of the narrow edge of the basin by the movable support plate. The entire narrow edge of the basin is supported by the movable support plate when it shrinks and realizes overall synchronous displacement, so that no moving surface is generated between the narrow edge of the basin and the movable support plate, and the friction between the narrow edge of the basin and the movable support plate is eliminated. In this way, the straightness of the narrow edge of the basin is guaranteed and the flatness of the narrow edge of the basin is guaranteed. After multiple tests, the straight edge error of the finished porcelain fired by the horizontal displacement of the movable support plate using the utility model can be reduced to less than 0.5 mm, reaching a level of refinement that cannot be distinguished by the naked eye.

[0029] 2. Solved the problem of basin panel distortion. The current method of flat-firing basins in the industry is to make a hole on a whole kiln plate that matches the basin core, and then fit the clay blank of the basin on the kiln plate and lay it flat for calcination. The narrow front edge of the basin is lighter in weight and has less friction. During calcination and shrinkage, it is farther away from the edge of the hole, and the basin core drops more, causing the narrow edge of the basin or the corner of the basin panel to warp up, resulting in distortion of the basin surface. The utility model uses a movable support plate to horizontally displace the narrow edge of the basin to achieve frictionless movement. The entire edge of the narrow edge of the basin is supported by the movable support plate during contraction and achieves overall synchronous displacement. The extent of the basin core dropping is balanced under the support of the entire movable support plate, and there is no possibility of the narrow edge of the basin or the corner of the basin panel warping up. Therefore, the problem of basin panel distortion is perfectly solved.

[0030] 3. It creates the possibility of narrowing the narrow edge of the basin to the limit. The size of the basin cavity of the current wash basin is certain, generally 55 cm long, 31 cm wide and 16 cm deep. The width of the basin cavity against the wall must be 12 cm wide to meet the installation size of the faucet. The use area of ​​the residents' bathroom is extremely limited. It is hoped that the width of the basin panel is as narrow as possible under the premise that the size of the basin cavity remains unchanged. Then, the only width that can be compressed is the narrow edge of the front of the basin cavity. From the production process point of view, if the narrow edge of the basin is too narrow, the deformation resistance of the blank itself is poor, especially the shrinkage amplitude during calcination is weaker in resistance to external forces, which will seriously affect the regularity of the narrow edge of the basin. From the current technological level in the industry, for thin-edged basins fired horizontally, the width of the narrow edge of the front of the basin cavity is generally about 6 cm. Therefore, the width of the entire basin must be more than 50 cm. The utility model of the flat-burning basin edge translation device realizes frictionless movement of the movable support plate holding the narrow edge of the basin by the horizontal displacement of the movable support plate. The entire edge of the narrow edge of the basin is supported by the movable support plate when shrinking and realizes overall synchronous displacement. The regularity of the narrow edge of the basin is not determined by its own width, but is forced to move as a whole by the movable support plate. In this way, we can design the narrow edge of the basin to be narrower to reduce the total width of the basin panel and make the bathroom more spacious. After adopting the utility model, the total width of the thin-edge basin we produce has been adjusted from more than 52 cm in the past to less than 49 cm under the premise that the size of the basin cavity remains unchanged, and the regularity of the product has also been further improved. If the user feels that it is convenient to use a basin, the size saved by designing the narrow edge can be used to design a double basin, one basin is specially used for spitting toothpaste foam and cleaning the mouth, and the other basin is kept clean for a long time. In this way, a lot of trouble in cleaning the basin can be reduced.

[0031] 4. Improved kiln climbing efficiency. During the production process, the clay blanks of thin-edged basins are very fragile, and the basin panels will break if not handled with care. When climbing the kiln, one person must lift the clay blank with great force to the top of the kiln plate hole, and then another person's hands must reach under the kiln plate hole to catch the basin, and then gently place the clay blank on the kiln plate. During operation, two people squeezed together in front of a narrow kiln tool are not easy to exert force, which is both laborious and prone to coordination errors; if a manipulator is used to climb the kiln, it is not economical, and the contact part of the manipulator operation is also easy to damage the glaze. The kiln tool design of the utility model of the flat-fired basin support and translation device is more convenient and flexible. The movable support plate can be placed on the roller at will. It can be taken away and placed aside before climbing the kiln. In this way, an open mouth is formed in front of the kiln plate. After the worker lifts the clay blank, he can directly place it on the kiln plate. One person can independently and quickly complete the whole process of climbing the kiln.

[0032] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required for use in the description of the embodiments will be briefly introduced below.

For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0033] Figure 1 It is a schematic diagram of the implementation structure of the side supporting and translating device for flat burning pots of the utility model.

[0034] In the figure: 1—movable support plate, 2—support plate horizontal plane, 3—movable platform, 4—rolling rod, 5—kiln hearth, 6—kiln plate, 7—kiln plate horizontal plane, 8—basin body mud, 9—basin panel, 10—basin liner corner, 11—panel corner, 12—basin narrow side, 13—basin liner. DETAILED DESCRIPTION

[0035] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. The described embodiments are only a part of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0038] Figure 1 The schematic diagram of the implementation structure of the flat-fired basin-type support and translation device of the utility model is shown. As shown in the figure, in order to facilitate the description of the actual process of kiln climbing operation and calcination of the flat-fired basin-type support and translation device, we also include the relevant clay parts in the figure. In fact, the kiln tool part can only include: movable support plate 1, support plate horizontal surface 2, movable platform 3, roller 4, kiln 5, kiln plate 6, kiln plate horizontal surface 7. The relevant clay parts include: basin body clay 8, basin panel 9, basin liner corner 10, panel corner 11, basin narrow edge 12, basin liner 13.

[0039] from Figure 1 It can be seen that the kiln plate 6 is a whole plate that matches the basin body mud blank 8. The kiln plate horizontal plane 7 coincides with the bottom plane of the basin body mud blank 8. The kiln sill 5 supports the kiln plate 6. The movable platform 3 and the kiln plate 6 are a whole. The rolling rod 4 is placed on the movable platform 3 and can roll freely forward and backward within a certain stroke. The movable support plate 1 is placed on the rolling rod 4 and can slide freely forward and backward in parallel within a certain stroke, and ensure that the support plate horizontal plane 2 is always on the same plane as the kiln plate horizontal plane 7.

[0040] During the kiln climbing process, after the basin body clay blank 8 is placed on the kiln plate 6, the basin liner 13 will automatically push the movable support plate 1 outward. In this way, the bottom plane of the basin body clay blank 8 is closely attached to the kiln plate horizontal plane 7 and the movable support plate horizontal plane 2, and the movable support plate 1 is at a certain distance from the kiln plate horizontal plane 7.

[0041] During the calcination process, when the kiln temperature reaches more than 1200 degrees, as the temperature drops, the clay body of the basin begins to shrink, and the final shrinkage is about 14%. During the shrinkage process, the bottom plane of the narrow edge 12 of the clay body 8 of the basin presses the movable support plate 1 and shrinks at the same time. It should be noted here that the narrow edge 12 of the basin is a long straight edge. When shrinking, the friction force at a certain point is greater and the shrinkage force is also greater. This straight edge is the entire side of the movable support plate 1. When a point on this straight edge generates a force that shrinks inward, the movable support plate 1 cannot be brought to slide inward. Only when every point of the entire narrow edge 12 of the basin has a force that shrinks inward can the entire edge shrink at the same time. In this way, it is ensured that the entire edge of the narrow edge 12 of the basin is both flat and straight.

[0042] In specific implementation, there are many options for the overall method and application range of realizing the narrow edge of the basin 12:

[0043] 1. The utility model is applicable to the flat-firing support plate for pans with side supports and pan shifting, including the flat-firing kiln designs for single and double pans. As long as it is necessary to ensure that the narrow side 12 of the pan is a designed straight line or an artistically curved shape, the kiln design and process method are universal.

[0044] 2. The movable support plate 1 can be designed to only support the narrow side 12 of the basin, or it can be designed to support other sides to achieve synchronous displacement.

[0045] 3. The design length of the movable support plate 1 is not limited. It can be designed to support the entire edge or only support the local part with key deformation.

[0046] 4. There are many structural options for forming a smooth displacement of the movable support plate 1, including a translation bracket, a temperature-resistant ball, a temperature-resistant roller, a temperature-resistant bearing support, a suspended bracket, a smooth trolley, etc.

[0047] 5. The movable support plate 1 is either designed inside or outside the frame of the kiln plate 6, or the movable support plate 1 is directly used as the frame of the kiln plate 6.

[0048] 6. The design shape of the movable support plate 1 is either a straight bar or a special shape with a certain curvature.

[0049] 7. The structure of the movable support plate 1 is either a stepped structure on the kiln plate 6, or a movable device of the movable support plate 1 is designed separately by relying on the lower kiln furniture or kiln 5 as a support.

[0050] 8. The material of the movable support plate 1 may be mullite, silicon carbide, silicon nitride or other high temperature resistant materials.

[0051] Undoubtedly, the utility model of the flat-burning pot side support translation device can also have a variety of changes and modifications, and is not limited to the specific structure of the above-mentioned embodiment, such as the various changes in the positioning structure of the heat-resistant pot bottom support, etc. In short, the protection scope of the utility model of the flat-burning pot side support translation device should also include those obvious exchanges, substitutions and modifications to ordinary technicians in the field.
