Technical Field

[0001] This invention belongs to the field of tableware forming equipment, specifically a two-color melamine tableware forming equipment and its process. Background Technology

[0002] The two-color melamine tableware molding equipment is a device for processing two-color melamine tableware. The processing steps are as follows: Install and preheat the mold on the molding machine. The mold preheating temperature is 170-180 degrees Celsius for 1 hour. The mold temperature during molding is 175 degrees Celsius. Prepare two custom-made raw material boxes of the same shape but different sizes, one large and one small. The diameter of the smaller box is 70%-80% of the diameter of the larger box. Based on the weight of the product, prepare two colors of melamine powder and add them to the two raw material boxes. The two boxes are filled with melamine powder in proportions: a large box containing 30-50mm of powder and a small box containing 15-25mm of powder. The boxes containing the raw materials are then placed in a 10KW high-frequency machine to bake the raw materials into cakes. The large box is baked for 50 seconds, and the small box for 65 seconds. After baking, the raw materials are formed into cakes. The larger cake is placed on a preheated mold, and the smaller cake is placed on top, aligned in the center. The pre-set molding program is then started to shape the product. The initial molding pressure is 100 tons, the molding pressure is 200 tons, with two venting cycles, each lasting 1.5 seconds, and the molding time is 80 seconds. After molding, the product is removed, and the rough edges are removed with tools, completing the molding process.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, an upper storage tank and a lower storage tank are respectively opened from top to bottom in the inner cavity of the storage tank. The inner diameter of the upper storage tank is larger than that of the lower storage tank, and the heating time of melamine in the lower storage tank is longer than that of melamine in the upper storage tank. This facilitates the sequential introduction of two-color melamine slurry, thereby facilitating the simultaneous heating and molding of the two-color melamine slurry and improving processing efficiency. 2. In this invention, a rotating shaft is driven by a rotating drive motor, which in turn drives the storage box to rotate. After the two-color melamine cake is heated and formed, it is inverted above the mold. The storage box and the pusher plate are moved relative to each other by a lifting drive motor, thereby extruding the formed two-color melamine cake onto the mold. This fixes the small-diameter melamine cake in the middle of the large-diameter melamine cake, improving processing efficiency and processing effect. 3. In this invention, two transverse tubes correspond to the lower transverse tube and the upper transverse tube respectively. By moving the transverse tubes, the required melamine slurry can be introduced into the lower and upper storage tanks, which facilitates the formation of two-color melamine cake blocks. At the same time, the end stop can seal one end of the transverse tube, which improves the melamine cake block forming effect. 4. In this invention, both the lower and upper horizontal pipes are connected to storage cylinders. The lower and upper horizontal pipes are respectively matched with corresponding horizontal pipes. An output pump can be used to input melamine slurry into the storage tank, while a suction pump can be used to suck the melamine slurry in the horizontal pipes, lower horizontal pipes, and upper horizontal pipes back into the storage cylinders, which is convenient for subsequent use.

[0023] Working principle: During use, two different colors of melamine raw materials are stored in two storage cylinders 5071 respectively. The mold on the molding machine is preheated at a temperature of 170-180 degrees Celsius for 1 hour. The mold temperature is 175 degrees Celsius during molding to complete the pre-processing preparation. Then, the fixing frame 1 is fixed to the bottom cylinder 301. The fixing block 3041 on the upper fixing member 304a is inserted into the inside of the U-shaped frame 4021 on the upper snap-fit ​​member 402a, and the fixing block 3041 on the lower fixing member 304b is inserted into the inside of the U-shaped frame 4021 on the lower snap-fit ​​member 402b, so that the snap-fit ​​rod 4023 is snapped into the inside of the side cylinder 4022, thereby fixing the fixing frame 1 and the bottom cylinder 301. Then, the moving drive motor 506 corresponding to the lower horizontal tube 501 is turned on, driving the lower horizontal tube 501 to move towards the storage tank 201, so that the lower horizontal tube 501 is inserted into the inner side of the transverse tube 2043 on the lower feed component 204a. After the end of the lower horizontal tube 501 contacts the fixing ring 2046, it pushes the transverse tube 2043 towards the inner cavity of the upper storage tank 203 until the feed hole 2045 moves above the lower storage tank 202. Then, the output pump 5074 on the connecting pipeline 5072 between the lower horizontal tube 501 and the storage cylinder 5071 is turned on, thereby driving the storage cylinder 5071. The monochromatic melamine inside is fed into the lower storage tank 202 through the lower horizontal pipe 501 and the horizontal pipe 2043. After the feeding is completed, the lower horizontal pipe 501 is driven to move back, and the horizontal pipe 2043 moves back under the elastic force of the first spring 2049, so that the end stop 2044 enters the side inner tank 2041. Then the suction pump 5075 is turned on to recover the monochromatic melamine in the lower horizontal pipe 501 and the horizontal pipe 2043 into the storage cylinder 5071. Finally, the lower horizontal pipe 501 is controlled to move back completely. During use, the valve 5076 on the connecting pipeline 5072 needs to be controlled to open and close. The material storage box 201 is fed into the 10KW high-frequency machine via a moving mechanism to heat the monochromatic melamine in the lower storage tank 202 inside the material storage box 201. After heating for 15 seconds, the monochromatic melamine in the lower storage tank 202 is heated and solidified. Then, the 10KW high-frequency machine is turned on, and through the above operation, the melamine on the other side is fed into the upper storage tank 203 through the upper horizontal pipe 502. Then, the 10KW high-frequency machine heats the two-color melamine simultaneously for 50 seconds, realizing the synchronous heating treatment of the two-color melamine and improving processing efficiency. After heating, the two-color melamine forms a cake shape and is then moved to the molding machine via a moving mechanism, causing the storage tank 201 to move above the mold. The drive motor 406 is then activated, driving the drive gear 405 to rotate. The drive gear 405 meshes with the driven gear 404 at one end of the rotating shaft 403, thereby rotating the longitudinal sliding frame 401 180 degrees, which in turn rotates the storage tank 201 180 degrees, inverting it. Then, the lifting drive motor 409 is activated, driving the first screw 408 to rotate, which in turn moves the sliding block 407 along the longitudinal sliding frame 401, causing the pusher plate 302 to engage with the storage tank. The material bins 201 move relative to each other, thereby extruding the two-color melamine cake blocks from the storage bins 201 onto the mold. At this time, the two-color melamine cake blocks are convex in shape. Then, the molding machine is turned on to extrude the two-color melamine cake blocks from top to bottom and press them into the mold. After molding, the processed tableware can be taken out and the burrs can be removed. The thickness of the one-color melamine cake blocks in the lower storage tank 202 is 15mm-25mm, and the thickness of the other-color melamine cake blocks in the upper storage tank 203 is 30mm-50mm. The initial pressure of the molding machine is 100 tons, the molding pressure is 200 tons, the venting is done twice, the venting time is 1.5 seconds each time, and the molding time is 80 seconds.
