[0002] Tableware made from processed melamine is safe, reliable, non-toxic, odorless, and highly durable, offering exceptional hardness and resistance to breakage. Another key feature is its ease of coloring, resulting in rich, delicate colors. Due to its comprehensive properties, melamine tableware has become an increasingly popular item in daily life.

[0003] When preheating melamine tableware, the raw materials are weighed on a tray according to the desired weight. The weighed materials are then placed in a high-frequency preheater for uniform heating, allowing the powdered raw materials to form into blocks. However, after preheating a batch of raw materials, the preheating device must be shut down, the top cover opened, and the raw materials removed before the next batch can be placed and preheated. This is inefficient. Furthermore, the preheating device needs to be reheated, increasing energy consumption and hindering energy conservation. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-4 The present invention provides a technical solution: a preheating device for a melamine tableware forming machine, comprising a main cabinet 1, a preheating chamber 2 disposed on the top of the main cabinet 1, and a preheating support plate 3 disposed within the interior of the preheating chamber 2. One end of a platform 4 is fixed to the top surface of the main cabinet 1, and the bottom ends of the preheating chamber 2 and the preheating support plate 3 are respectively connected to the top surface of the platform 4. A rectangular opening 2.1 is provided on the side of the preheating chamber 2 corresponding to the extension direction of the platform 4, corresponding to the top surface of the preheating support plate 3.

[0031] One end of the slide 5 is fixed to the side wall of the preheating chamber 2 at a position corresponding to the lower edge of the rectangular hole 2.1; a slide groove 5.1 is provided in the middle of the slide 5, and a support beam 5.2 is connected between the bottom surface of the outer end of the slide 5 and the top surface of the platform 4.

[0032] The bottom ends of the tunnel cavity 6 are respectively fixed to the front and rear walls on the inner side of the middle portion of the slide plate 5 , and the inner end of the tunnel cavity 6 is sealedly connected to the outer edge of the rectangular opening 2 . 1 .

[0033] The sealing plate 7 is slidably sleeved in the rectangular hole 2.1.

[0034] The second sealing plate 8 is slidably connected with the rectangular opening 2.1 and the inner cavity of the tunnel cavity 6. A top block 8.1 is fixed in the middle of the inner wall of the second sealing plate 8, and a through hole 8.2 is provided near the front and rear ends of the second sealing plate 8.

[0035] The inner end of the telescopic rod 9 is vertically fixed to the outer wall of the sealing plate 1 7 near the front and rear ends, and the outer end of the telescopic rod 9 is slidably connected to the sealing plate 2 8. The push-pull connector 10 is fixedly connected to the outer end of the telescopic rod 9. The telescopic rod 9 includes an outer sleeve 9.1 whose inner end is vertically fixed to the outer wall of the sealing plate 1 7, and an inner rod body 9.2 that is movably connected to the inner cavity of the outer sleeve 9.1 and slidably connected to the through hole 8.2. The outer edge of the inner end of the inner rod body 9.2 is equipped with a flange with an outer diameter larger than the inner diameter of the outer sleeve 9.1.

[0036] The push-pull connector 10 comprises a slider 10.2 which is slidably engaged in the slide groove 5.1, a slat 10.1 fixed to the top of the slider 10.2 at the middle of the bottom surface, and a threaded sleeve 10.3 fixedly sleeved between the two side walls of the bottom end of the slider 10.2. The front and rear ends of the slat 10.1 are provided with sleeve holes 10.1.1 fixedly connected to the outer end of the inner rod body 9.2.

[0037] The servo motor 12 is installed in the middle of the outer side wall of the support beam 5.2, and the power output shaft of the servo motor 12 is fixedly connected to a screw rod 11 that matches the threaded sleeve 10.3.

[0038] In summary, before the melamine tableware is formed and processed, the melamine raw materials are preheated, and the melamine powder to be preheated is first placed in a tray. The tray is then placed on the top surface of the slide 5 and located inside the second sealing plate 8. The servo motor 12 drives the screw 11 to rotate. The rotating screw 11 drives the push-pull connector 10 to move inward as a whole through the threaded sleeve 10.3, thereby pushing the second sealing plate 8. At the same time, the inner rod body 9.2 gradually retracts into the outer sleeve 9.1. When the second sealing plate 8 is inserted into the outer end of the inner cavity of the tunnel cavity 6, the inner rod body 9.2 is completely retracted into the outer sleeve 9.1. The push-pull connector 10 continues to move inward under the action of the screw drive mechanism. At this time, the slats 10.1 will directly push the sealing plate 1 7 through the outer sleeve 9.1 to move toward the inner cavity of the preheating cavity 2 until the tray is pushed to the top surface of the preheating support plate 3, and the second sealing plate 8 is just inserted into the rectangular hole 2.1.

[0039] After the melamine powdered raw material is preheated in the preheating chamber 2, the servo motor 12 drives the screw 12 to rotate in the opposite direction, thereby causing the push-pull connector 10 to move outward, first pulling the inner rod 9.2 outward. After the inner rod 9.2 is completely pulled out of the outer sleeve 9.1, the outer sleeve 9.1 will be pulled. When the outer sleeve 9.1 moves outward, it pushes the sealing plate 2 8 from the inside to move outward while pulling the sealing plate 1 7. When the sealing plate 1 7 is re-inserted into the rectangular hole 2.1, the sealing plate 2 8 also moves to the outer end of the inner cavity of the tunnel cavity 6. The push-pull connector 10 returns to its original position, and the sealing plate 2 8 is manually moved to the outer end of the top surface of the slide 5 to facilitate the removal of the preheated melamine powdered raw material and the addition of new melamine powdered raw material to be preheated. During the entire feeding and discharging process, the inner cavity of the preheating chamber 2 is always isolated from the external environment, thereby preventing heat loss. In order to facilitate pulling the closing plate 2 8 and the tray outward, pulling handles are respectively provided on the outer side wall of the closing plate 2 8 and the outer side of the tray.

[0040] The top block 8.1 on the inner wall of the second sealing plate 8 facilitates pushing the tray onto the preheating support plate 3 while the second sealing plate 8 is inserted into the rectangular hole 2.1. The main cabinet 1, the preheating cavity 2 and the preheating support plate 3 are respectively components of an existing high-frequency preheating machine.

[0041] The inner end of the top surface of the tunnel cavity 6 is provided with a plurality of vertical holes 6.1. Positions corresponding to the vertical holes 6.1 are provided on the top surface of the tunnel cavity 6, respectively, with pressing locators 13. These pressing locators 13 comprise a cylindrical body 13.1 with its bottom end fixed to the outer edge of the top end of the vertical hole 6.1, a spring 13.2 with its top end connected to the top surface of the inner cavity of the cylindrical body 13.1, and a conical head 13.3 with its top surface connected to the bottom end of the spring 13.2 and slidably engaged with the vertical hole 6.1. The pressing action of the pressing locators 13 facilitates the compression of the sealing plate inserted into the rectangular opening 2.1, providing a certain resistance to its lateral sliding, thereby preventing the sealing plate from moving even when subjected to slight force.
