Description
Technical Field
[0001] This utility model belongs to the field of melamine tableware production technology, specifically a tableware hot pressing molding device. Background Technology
[0002] Melamine bowls, also known as imitation porcelain bowls, are made by heating and pressing melamine resin powder into shape. Due to their lightweight, attractive appearance, low-temperature resistance, and durability, melamine bowls are widely used in the catering and children's food industries. The production process of melamine bowls mainly includes mixing, weighing, molding, and post-processing. Specifically, the molding and post-processing steps involve hot pressing and edge polishing. The production of melamine bowls involves extruding preheated melamine material through a hot pressing mold to create semi-finished melamine tableware.
[0003] In this process, after the semi-finished melamine tableware is cooled, the edges and corners of the semi-finished melamine bowl need to be polished in the subsequent edge polishing process.
[0004] In existing technologies, some of the melamine material being extruded may overflow from the gaps in the mold. After cooling, this overflows and becomes excess material, which not only wastes material but also increases subsequent polishing work and production costs.
[0005] Therefore, this utility model provides a tableware hot pressing forming device. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A tableware molding device of this utility model includes a worktable; a guide rail is fixedly connected to the middle of the worktable; a top plate is fixedly connected to the top of the worktable; a first cylinder is fixedly connected to the bottom of the top plate; a fixed plate is fixedly connected to the bottom of the first cylinder; a moving mold is fixedly connected to the bottom of the fixed plate; a discharge pipe is connected to the top of the moving mold; a slider is slidably connected to the middle of the guide rail; a first motor is fixedly connected to the top of the slider; a base plate is fixedly connected to the top of the first motor; a fixed mold is fixedly connected to the top of the base plate; a limiting ring is provided on the outer side of the fixed mold; the limiting ring is fixedly connected to the base plate. During operation, the preheated tableware is first... The melamine material is placed inside the limiting ring. The guide rail is activated, moving the slider below the moving mold. The first cylinder is activated, causing the fixed plate to descend, which in turn causes the moving mold to descend, bringing the moving mold into contact with the fixed mold. The outer side of the moving mold then contacts the limiting ring, pressing the melamine material into shape. The limiting ring abuts against the gap between the moving mold and the base plate, reducing the amount of melamine material that overflows from the gap during pressing, thus preventing excess scrap. Then, the first cylinder moves the moving mold away from the base plate. If the semi-finished product is still attached to the moving mold, it can be pressed into the discharge pipe to detach it from the moving mold. The melamine material is then placed on the base plate. The limiting ring fills the gap between the moving mold and the base plate, reducing the amount of melamine material that overflows from the gap during pressing, thus preventing material waste.
[0008] Preferably, air guide plates are provided on both sides of the moving mold. The air guide plates are fixedly connected to the top plate. An external air pipe is connected to one side of the air guide plate, and multiple air holes are connected to the other side of the air guide plate. During operation, after the melamine material is pressed into a semi-finished product, cold air is introduced through the external air pipe. The cold air is released from the air holes and acts on the semi-finished product to cool it down and accelerate its cooling, so as to facilitate subsequent polishing operations. By setting up air guide plates, external air pipes, and air holes to conduct cold air, the cold air carries away the heat of the semi-finished product and accelerates the air circulation around the semi-finished product, thereby achieving the effect of rapid cooling of the semi-finished product.
[0009] Preferably, a second cylinder is provided on one side of the first cylinder. The second cylinder is fixedly connected to the top plate, and a horizontal plate is fixedly connected to the bottom of the second cylinder. Two second motors are fixedly connected to the top of the horizontal plate, and a grinding block is fixedly connected to the bottom of the second motor. During operation, after the moving mold presses the semi-finished product, the external air pipe conducts cold air to cool the semi-finished product. During this process, the guide rail is activated, driving the slider to the bottom of the second cylinder. During transportation, the cold air continuously acts on the fixed mold, cooling the semi-finished product while cleaning its surface to reduce dust and impurities. Subsequently, the second cylinder is activated, driving the horizontal plate to descend, and then the second motor is activated, and the grinding block grinds the fixed mold. During this process, the cold air blows away debris, reducing debris from remaining on the semi-finished product, and also cleans the guide rail, reducing the phenomenon of debris sticking to the guide rail and causing the slider to jam.
[0010] Preferably, a sleeve is fixedly connected to the bottom of the horizontal plate, a spring is fixedly connected to the top of the sleeve, and a limiting block is fixedly connected to the bottom of the spring. The limiting block is slidably connected to the sleeve. During operation, the limiting block descends with the horizontal plate and abuts against the top of the semi-finished product. Under the action of the spring, the semi-finished product can be fixed, reducing the shaking phenomenon during grinding, and also reducing the phenomenon of excessive pressure on the semi-finished product causing indentations.
[0011] Preferably, the guide rail is provided with collection grooves on both sides. The collection grooves are opened on the surface of the worktable. During operation, the debris generated by grinding is guided by the cold air emitted from the air hole to drift to both sides of the worktable and gather in the collection grooves, which facilitates the subsequent centralized processing of debris.
[0012] Preferably, a baffle is provided on one side of the collection tank. The baffle is fixedly connected to the workbench. During operation, the baffle prevents debris from scattering everywhere and leaving the workbench, making subsequent cleaning inconvenient.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The tableware molding device of this utility model reduces the phenomenon of melamine material overflowing from the gaps during the pressing process by setting a limiting ring to fill the gap between the top mold and the bottom plate, thus reducing material waste.
[0015] 2. The tableware molding device of this utility model conducts cold air by setting an air guide plate, an external air pipe, and air holes. The cold air carries away the heat of the semi-finished product and accelerates the air circulation around the semi-finished product, thereby achieving the effect of rapid cooling of the semi-finished product.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 3 As shown in the embodiment of this utility model, a tableware molding device includes a workbench 1; a guide rail 11 is fixedly connected to the middle of the workbench 1, a top plate 12 is fixedly connected to the top of the workbench 1, a first cylinder 13 is fixedly connected to the bottom of the top plate 12, a fixed plate 14 is fixedly connected to the bottom of the first cylinder 13, a moving mold 15 is fixedly connected to the bottom of the fixed plate 14, a discharge pipe 16 is connected to the top of the moving mold 15, a slider 17 is slidably connected to the middle of the guide rail 11, a first motor 18 is fixedly connected to the top of the slider 17, a base plate 19 is fixedly connected to the top of the first motor 18, a fixed mold 110 is fixedly connected to the top of the base plate 19, a limiting ring 111 is provided on the outer side of the fixed mold 110, and the limiting ring 111 is fixedly connected to the base plate 19. During operation, preheated melamine material is first placed on the limiting ring 11. Within step 1, the guide rail 11 is activated, moving the slider 17 below the moving mold 15. The first cylinder 13 is activated, causing the fixed plate 14 to descend, which in turn causes the moving mold 15 to descend, making the moving mold 15 fit against the fixed mold 110. The outer side of the moving mold 15 fits against the limiting ring 111, pressing the melamine material into shape. The limiting ring 111 abuts against the gap between the moving mold 15 and the base plate 19, reducing the overflow of melamine material from the gap during the pressing process, thus preventing the generation of excess scrap. Then, the first cylinder 13 drives the moving mold 15 to detach from the base plate 19. If the semi-finished product fits against the moving mold 15, it can be pressed into the discharge pipe 16 to detach the semi-finished product from the moving mold 15. The melamine material is placed on the base plate 19. By setting the limiting ring 111 to fill the gap between the moving mold 15 and the base plate 19, the overflow of melamine material from the gap during the pressing process is reduced, preventing material waste.
[0025] like Figures 1 to 4As shown, air guide plates 2 are provided on both sides of the moving mold 15. The air guide plates 2 are fixedly connected to the top plate 12. An external air pipe 21 is connected to one side of the air guide plate 2, and multiple air holes 22 are connected to the other side of the air guide plate 2. During operation, after the melamine material is pressed into a semi-finished product, cold air is introduced through the external air pipe 21. The cold air is emitted from the air holes 22 and acts on the semi-finished product to cool it down and accelerate the cooling process, so as to facilitate subsequent polishing operations. By setting up the air guide plates 2, external air pipes 21, and air holes 22 to conduct cold air, the cold air carries away the heat of the semi-finished product and accelerates the air circulation around the semi-finished product, thereby achieving the effect of rapid cooling of the semi-finished product.
[0026] like Figures 1 to 5 As shown, a second cylinder 3 is provided on one side of the first cylinder 13. The second cylinder 3 is fixedly connected to the top plate 12. A horizontal plate 31 is fixedly connected to the bottom of the second cylinder 3. Two second motors 32 are fixedly connected to the top of the horizontal plate 31. A grinding block 33 is fixedly connected to the bottom of the second motor 32. During operation, after the moving mold 15 presses the semi-finished product, the external air pipe 21 conducts cold air to cool the semi-finished product. During this process, the guide rail 11 starts, driving the slider 17 to the bottom of the second cylinder 3. During transportation, the cold air continuously acts on the fixed mold 110, cooling the semi-finished product and cleaning its surface to reduce dust and impurities. Then, the second cylinder 3 starts, driving the horizontal plate 31 to descend, and then the second motor 32 starts, and the grinding block 33 grinds the fixed mold 110. During this process, the cold air blows away debris, reducing debris from remaining on the semi-finished product, and also cleans the guide rail 11, reducing debris from sticking to the guide rail 11 and causing the slider 17 to jam.
[0027] like Figures 1 to 5 As shown, a sleeve 4 is fixedly connected to the bottom of the horizontal plate 31, a spring 41 is fixedly connected to the top of the sleeve 4, and a limiting block 42 is fixedly connected to the bottom of the spring 41. The limiting block 42 is slidably connected to the sleeve 4. During operation, the limiting block 42 descends with the horizontal plate 31 and abuts against the top of the semi-finished product. Under the action of the spring 41, the semi-finished product can be fixed, reducing the shaking phenomenon during grinding, and also reducing the phenomenon of excessive pressure on the semi-finished product causing indentations.
[0028] like Figure 2 As shown, the guide rail 11 is provided with collection grooves 5 on both sides. The collection grooves 5 are opened on the surface of the workbench 1. During operation, the grinding debris is guided by the cold air emitted from the air hole 22 to drift to both sides of the workbench 1 and gather in the collection grooves 5, which facilitates the subsequent centralized processing of debris.
[0029] like Figure 1As shown, a baffle 6 is provided on one side of the collection tank 5. The baffle 6 is fixedly connected to the workbench 1. During operation, the baffle 6 prevents debris from scattering everywhere and leaving the workbench 1, making subsequent cleaning inconvenient.
[0030] Working principle: First, the preheated melamine material is placed inside the limiting ring 111. The guide rail 11 is activated, moving the slider 17 below the moving mold 15. The first cylinder 13 is activated, causing the fixed plate 14 to descend, which in turn causes the moving mold 15 to descend, bringing it into contact with the fixed mold 110. The outer side of the moving mold 15 then contacts the limiting ring 111, pressing the melamine material into shape. The limiting ring 111 abuts against the gap between the moving mold 15 and the base plate 19, reducing the amount of melamine material overflowing from the gap during pressing and preventing excess scrap. Then, the first cylinder 13 moves the moving mold 15 away from the base plate 19. If the semi-finished product is attached... The moving mold 15 can press into the discharge pipe 16, causing the semi-finished product to detach from the moving mold 15. The melamine material is placed on the base plate 19. The gap between the moving mold 15 and the base plate 19 is filled by the limiting ring 111 to reduce the overflow of melamine material from the gap during the pressing process, thus reducing material waste. After the melamine material is pressed into a semi-finished product, cold air is introduced through the external air pipe 21 and emitted from the air hole 22, acting on the semi-finished product to cool it down and accelerate the cooling process, which is conducive to subsequent polishing operations. The cold air is conducted through the air guide plate 2, the external air pipe 21, and the air hole 22, and the cold air carries away the heat of the semi-finished product, accelerating the cooling process. Air circulation around the semi-finished product enables rapid cooling. After the moving mold 15 presses the semi-finished product, the external air pipe 21 conducts cold air to cool it. During this process, the guide rail 11 is activated, moving the slider 17 to the bottom of the second cylinder 3. During transport, the cold air continuously acts on the fixed mold 110, cooling the semi-finished product while cleaning its surface to reduce dust and impurities. Subsequently, the second cylinder 3 is activated, causing the horizontal plate 31 to descend, which in turn activates the second motor 32. The grinding block 33 grinds the fixed mold 110. During this process, the cold air disperses debris, reducing its accumulation on the semi-finished product. The guide rail 11 is cleaned to reduce debris from sticking to it and causing the slider 17 to jam. The limiting block 42 descends with the horizontal plate 31 and abuts against the top of the semi-finished product. Under the action of the spring 41, the semi-finished product is fixed, reducing shaking during grinding, and also reducing the possibility of indentation caused by excessive pressure on the semi-finished product. The debris generated during grinding is guided by the cold air emitted from the air hole 22 to drift to both sides of the worktable 1 and gather in the collection tank 5, which facilitates the subsequent centralized treatment of debris. The baffle 6 prevents debris from drifting everywhere and leaving the worktable 1, making it inconvenient for subsequent cleaning.
