Description

Technical Field

[0001] The utility model relates to the technical field of processing ceramic rock slab integrated basins, and in particular to an arc-shaped forming device for a drain outlet of a ceramic rock slab integrated basin. Background Art

[0002] In the past decade, stone slabs have been widely used in surface decoration, bathroom, furniture countertops, furniture panels and other scenarios due to their large extension surface, strong texture plasticity, light weight, thin thickness, slightly lower firing temperature and energy saving and emission reduction characteristics compared to traditional ceramic tiles.

[0003] In the niche field of bathroom counter basins, the molding process of rock slabs can generally only make straight plates, and it is difficult to use ceramic, plastic, stainless steel and other molding processes (i.e. mold pressing, suction and then heat forming, etc.) to make washbasins with greater depth. Therefore, although rock slab integrated washbasins have a large market, high-quality products are rare.

[0004] In recent years, many manufacturers have paid attention to the use of hot bending technology to shape rock slabs, such as CN111960653A and CN114646218B. The former provides a process for hot bending of rock slabs, so that rock slabs can be shaped into concave and convex arcs, folded edges, waves and other shapes; the latter provides a solution to make the hot bending process more suitable for the mold. However, these solutions can only solve the problem of hot bending shaping of rock slabs with large extension surfaces, but there has been no good solution for the rock slab shape of ceramic rock slab integrated basins, which have a small extension surface, a deep basin depth, and a partially sunken shape.

[0005] In fact, the hot bending forming device of the rock slab generally includes a high-temperature kiln and a prefabricated basin-shaped mold set in the high-temperature kiln. The rock slab is placed in the prefabricated basin-shaped mold. Under high-temperature heating conditions, the rock slab sinks by its own weight along the sunken shape of the basin-shaped mold to form a ceramic rock slab integrated basin. The bottom of the existing ceramic rock slab integrated basin is generally equipped with a drain. Before installing the drain, it is necessary to open a drain hole on the ceramic rock slab integrated basin. In the actual processing procedure, the drain hole is generally obtained by opening the hole using a separate cutting machine after the integrated basin is hot-bent.

[0006] However, the existing integrated basin drains often have the following problems during the manufacturing process:

[0007] 1. The drain of the existing integrated basin is generally located in the middle of the relatively flat bottom of the integrated basin, and is in the shape of a flat circular hole, without involving the drain chamfer (i.e. the drain is funnel-shaped). Therefore, it cannot be guaranteed that the drain position is the lowest position of the basin body, which is not conducive to draining, so that water still accumulates near the drain after draining. In addition, the existing rock plate hot bending forming device cannot achieve hot bending and drain chamfering at one time, nor can it obtain the drain chamfering angle from the subsequent cutting process. The processing process is cumbersome and the production cost is high.

[0008] 2. Due to the differences in the materials of each batch of ceramic rock slabs, the ceramic rock slabs are prone to uneven effects during the high-temperature hot bending process, especially at the drain position, making it difficult to achieve standardized molding of the drain. Utility Model Content

[0009] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide an arc-shaped forming device for the drain outlet of a ceramic rock slab integrated basin, which simultaneously forms a funnel-shaped drain outlet during the hot bending process of the rock slab, so that the arc-shaped chamfer of the drain outlet of the ceramic rock slab integrated basin is formed at one time, and the obtained arc-shaped chamfer of the drain outlet is uniform in size and position, thereby avoiding water accumulation at the bottom of the ceramic rock slab integrated basin, reducing cumbersome processing steps, and reducing production costs.

[0011] When the high-temperature kiln is heating, the ceramic rock slab sinks into the cavity of the integrated basin hot bending mold under the action of its own weight and the counterweight block. During the synchronous sinking process, the central axis rod forms a water outlet groove at the preset water outlet forming position of the ceramic rock slab, and the connection position between the water outlet groove and the bottom of the integrated basin has an arc-shaped chamfer.

[0013] Preferably, before the high-temperature kiln heating operation, the height distance between the outer sleeve and the counterweight block is equal to the depth of the cavity of the integrated basin hot bending mold, and the cavity depth of the lower water groove is obtained according to the sinking of the molded ball according to its own weight under heating conditions.

[0014] Preferably, the arc-shaped forming device for the drain outlet of the ceramic rock slab integrated basin also includes a forming ball arranged below the central axis rod, and the diameter of the forming ball is adapted to the preset inner diameter of the drain outlet of the ceramic rock slab.

[0015] Preferably, the arc-shaped forming device for the drain outlet of the ceramic rock slab integrated basin also includes high-temperature cotton or ceramic roller coating placed under the forming ball to prevent the forming ball and the ceramic rock slab from sticking to each other during the sinking process.

DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0034] like Figure 1-5 As shown, a ceramic rock plate integrated basin water outlet arc forming device comprises a high temperature kiln 1, an integrated basin hot bending mold 2 arranged in the high temperature kiln 1, a central axis rod 3, a counterweight block 4, and a mounting bracket 5; the ceramic rock plate piece A to be processed is horizontally placed on the upper surface of the integrated basin hot bending mold 2, and the integrated basin hot bending mold 2 is placed on the kiln frame 13 in the high temperature kiln 1, and the kiln frame 13 can be reciprocated for loading and unloading. Before loading, no water hole is excavated on the ceramic rock plate piece A, and the forming ball 8 is placed on the preset water outlet forming position A0 of the ceramic rock plate piece A; the mounting bracket 5 moves and is erected above the ceramic rock plate piece A, the central axis rod 3 is movably inserted on the mounting bracket 5, the bottom of the central axis rod 3 is located above the preset water outlet forming position of the ceramic rock plate piece, and the counterweight block 4 is fixed on the top of the central axis rod 3. After loading, the kiln frame 13 is sent into the high temperature kiln 1 for firing.

[0035] When the high-temperature kiln 1 is heating, the ceramic rock slab A sinks into the cavity of the integrated basin hot bending mold 2 under the action of its own weight and the counterweight block 4. The central axis rod 3 forms a water outlet groove A1 at the preset water outlet forming position A0 of the ceramic rock slab A during the synchronous sinking process. The water outlet groove A1 has an arc-shaped guide angle A2 at the connection position with the bottom of the integrated basin.

[0036] The molding device in this example increases the mounting bracket 5 for mounting the counterweight 4 and the central axis 3, adjusts the matching connection relationship between the counterweight 4, the central axis 3 and the mounting bracket 5, so as to limit the sinking range of the counterweight 4 and the central axis 3, improve the sinking stability of the central axis 3, improve the molding quality of the cavity and the water tank of the integrated plate, and improve the uniformity of the wall thickness of the water tank. In addition, the use of counterweights to increase the molding speed can effectively reduce production energy consumption. Under the same molding effect, this device can effectively shorten the firing time of the high-temperature kiln 1 and reduce production costs.

[0037] In this solution, the mounting bracket 5 can provide at least one support point for the central axis rod 3. Of course, the more support points there are, the smoother the sinking of the central axis rod 3. Technical personnel in this field can set one or more layers of mounting brackets according to the sinking stability requirements of the central axis rod 3, which will not be repeated here.

[0038] The forming device simultaneously forms a drain groove A1 during the hot bending process of the ceramic rock plate, so that the connection position between the bottom of the ceramic rock plate integrated basin and the drain groove is an arc-shaped chamfer A2, and is formed in one step. Finally, a simple hole is opened at the bottom of the drain groove A1 by using a tool to obtain a ceramic rock plate integrated basin B with a drain groove B1 and a basin body integrally formed. Figure 5The ceramic rock plate integrated basin produced by the molding device has a uniform size and position of the drain port, and a high degree of standardization, which avoids water accumulation at the bottom of the ceramic rock plate integrated basin, reduces cumbersome processing procedures, and reduces production costs.

[0039] As a further preferred embodiment, the arc-shaped forming device for the drain outlet of an integrated ceramic rock slab basin also includes an inner sleeve 6 and an outer sleeve 7, wherein the inner sleeve 6 is sleeved on the outer side of the central axis rod 3, and the inner sleeve 6 and the central axis rod 3 are movably arranged together on the mounting bracket 5; the outer sleeve 7 is sleeved on the outer side of the inner sleeve 6, and the outer sleeve 7 is arranged on the mounting bracket 5.

[0040] The inner sleeve 6 and the central axis rod 3 are movably arranged in the mounting bracket 5, and move downward under the action of the counterweight 4, and the role of the inner sleeve 6 is to provide a certain buffer for the sinking of the central axis rod 3 to prevent the ceramic rock plate from being punctured. In addition, since the height of the central axis rod 3 is relatively high, and the counterweight 4 is fixed on the top of the central axis rod 3, it is easy to produce a top-heavy situation. The additional mounting bracket 5 avoids the above-mentioned shortcomings to a certain extent. In order to further improve the stability of sinking, the present application also adds an outer sleeve 7, which is fixed on the mounting bracket 5. The limiting effect of the outer sleeve 7 is used to increase the contact area between the outer sleeve 7 and the central axis rod 3, and the sinking stability of the counterweight 4 is further improved to a certain extent.

[0041] As a further preferred solution, before the high-temperature kiln 1 is heated, the height distance H1 between the outer sleeve 7 and the counterweight block 4 is equal to the depth H2 of the cavity of the integrated basin hot bending mold 2, and the cavity depth of the lower water groove A1 is obtained according to the sinking of the molding ball 8 according to its own weight under heating conditions. Preferably, the cavity depth H3 of the lower water groove A1 is equal to the diameter width of the molding ball 8.

[0042] The present application designs and adjusts the height distance between the outer sleeve 7 and the counterweight 4 to match the depth of the cavity of the integrated basin hot bending mold 2, so that after the counterweight 4 sinks and abuts against the outer sleeve 7, the counterweight 4 no longer sinks. At this time, the molding ball 8 sinks according to its own weight under high temperature conditions to form a cavity for the water channel A1, and the depth of the cavity is matched with the diameter width of the central axis rod 3, which can improve the stability and smoothness of the molding of the water channel A1. The resulting water channel A1 has a uniform shape and size and a high degree of standardization.

[0043] As a further preferred embodiment, the arc-shaped forming device for the drain outlet of the ceramic rock slab integrated basin also includes a forming ball 8 arranged below the central axis rod 3, and the diameter of the forming ball 8 is adapted to the preset inner diameter of the drain outlet of the ceramic rock slab component A.

[0044] As a further preferred embodiment, the arc-shaped forming device for the drain outlet of the integrated ceramic rock plate basin further includes high-temperature cotton or ceramic roller coating (not shown) placed under the forming ball 8 to prevent the forming ball 8 and the ceramic rock plate part A from sticking to each other during the sinking process. The high-temperature cotton is placed directly under the central axis rod 3 or the forming ball 8 before being heated by the high-temperature kiln 1 to separate the central axis rod 3 or the forming ball 8 from the ceramic rock plate part A.

[0045] As a further preferred solution, the arc-shaped forming device for the drain outlet of the ceramic rock plate integrated basin further includes an automated sliding device 9 and a control system (not shown in the figure), wherein the automated sliding device 9 is installed at the bottom of the mounting bracket 5, and the control system controls the mounting bracket 5 to slide back and forth along the length direction of the automated sliding device 9. The present application improves the automation level of the entire forming device and improves production efficiency by designing an automated controlled sliding device.

[0046] As a further preferred solution, the integrated basin heat bending mold 2 is provided with an indented cavity that matches the indented depth and shape of the ceramic rock plate integrated basin, and the bottom of the indented cavity is provided with a slot opening for forming the drain trough A1 after the ceramic rock plate A is heat-bent. The integrated basin heat bending mold 2 of the present application can utilize the existing heat bending mold, and a slot opening is provided at the bottom of the mold to produce an integrated tray with an arc-shaped chamfer A2, without the need for additional mold opening costs, thereby reducing production costs.

[0047] As a further preferred embodiment, the arc-shaped forming device for the drain outlet of the ceramic rock plate integrated basin further includes a base 10 disposed below the integrated basin hot bending mold 2, and the base 10 is located directly below the central axis 3. The design of the base 10 is conducive to cooperating with the sinking of the central axis 3 or the forming ball 8, thereby improving the stability of the drain outlet A1.

[0048] As a further preferred solution, a silicon carbon rod 11 for heating is provided in the high temperature kiln 1. The present application designs the silicon carbon rod 11 as a heating device to replace the existing heating wire, thereby preventing the heating wire from being easily oxidized and thereby increasing the production service life of the equipment. Under the action of the counterweight block 4, the sinking and forming speed of the one-piece basin is accelerated, the heating time and temperature are reduced, and energy consumption is greatly saved.

[0049] As a further preferred solution, the high temperature kiln 1 is provided with a plurality of temperature control sensors 12 for monitoring the kiln temperature, and the temperature control sensors 12 are arranged on the side walls and the top wall of the high temperature kiln 1. Designing a plurality of temperature control sensors 12 can accurately ensure the heating temperature in the high temperature kiln 1 and improve the energy-saving controllable effect.

[0050] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
