Technical Field

[0001] This utility model belongs to the field of preheater technology, specifically relating to a high-frequency preheater with high-efficiency feeding. Background Technology

[0002] High-frequency preheating machines work on the principle of high-frequency medium heating. High frequency uses a high-frequency electromagnetic field to cause intense collisions between molecules inside the material, generating high temperatures to achieve welding, fusion, and preheating purposes. They are commonly used in the processing of melamine tableware.

[0003] In the current melamine tableware processing, the top cover of the high-frequency preheating machine needs to be opened manually to put the melamine in for preheating. Then, the powder needs to be manually taken out of the high-frequency preheating machine and poured into the mold for stamping. The machine's top cover needs to be opened and closed repeatedly for loading and unloading, resulting in low material loading efficiency, high energy consumption, and low efficiency, which has certain limitations. Utility Model Content

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model adopts an automatic lifting and closing mechanism for opening and closing the lid, eliminating the need for manual opening, which is more convenient. It can also automatically switch positions for feeding, improving preheating efficiency.

[0011] 2. This utility model uses existing technology to generate magnetic adsorption when electricity is applied to adsorb and fix the material tray, making the processing more stable. After processing is completed, the magnetic adsorption effect is canceled when the power is turned off, so that the material tray can be removed and unloaded. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a high-frequency preheating machine for efficient material feeding, including a processing table 1, a fixed bracket 2 fixedly connected to one side of the upper end of the processing table 1, a lifting cylinder 3 fixedly connected to the upper end of the fixed bracket 2, an upper cover plate 4 fixedly connected to one end of the shaft of the lifting cylinder 3, a heating plate 5 fixedly connected to the center of the lower end of the upper cover plate 4, a shifting motor 6 fixedly connected to the lower end of the processing table 1, a shifting turntable 7 fixedly connected to the shifting motor 6 via a shaft, a preheating base 8 fixedly connected to the upper end of the shifting turntable 7, four preheating bases 8, an electric lifting shaft 9 fixedly connected to the center of the preheating base 8, and a material placement tray 10 provided at the upper end of the electric lifting shaft 9.

[0018] In this embodiment, the raw materials are placed inside the material tray 10. After the power is turned on, the positioning motor 6 can drive the preheating base 8 to rotate and change position, so that the material tray 10 can rotate to the bottom of the upper cover plate 4. At this time, the lifting cylinder 3 lifts and moves the upper cover plate 4 to cover the upper end of the preheating base 8, so that the material tray 10 is sealed inside the preheating base 8. At this time, the existing heating plate 5 is powered on to preheat the raw materials inside the material tray 10. This design adopts an automatic lifting and closing method to open and close the cover without manual opening, which is more convenient and can automatically change position for feeding, thus improving the preheating efficiency.

[0019] Specifically, a feeding mechanical gripper 11 is fixedly connected to one side of the upper end of the processing table 1, and a unloading mechanical gripper 12 is fixedly connected to the other side of the upper end of the processing table 1.

[0020] In this embodiment, the feeding mechanical gripper 11 can grab the material tray 10 and place it on the upper end of the electric lifting shaft 9. After rotation for preheating, it can rotate to change position and then the unloading mechanical gripper 12 can grab the material tray 10 for unloading.

[0021] Specifically, the upper four corners of the preheating base 8 are fixedly provided with limit insertion holes 13, and the lower four corners of the upper cover plate 4 are fixedly connected with limit insertion posts 14, which can be inserted into the inside of the limit insertion holes 13.

[0022] In this embodiment, the limiting plug 14 can be inserted into the limiting hole 13, which has a certain positioning function, so that the upper cover plate 4 can be more accurately covered on the upper end of the preheating base 8.

[0023] Specifically, a magnetic chuck 15 is fixedly connected to the upper end of the electric lifting shaft 9, and a metal base plate 16 is fixedly connected to the lower end of the material tray 10.

[0024] In this embodiment, the magnetic chuck 15, after being powered on, can magnetically adhere to the bottom of the metal base plate 16, allowing the material tray 10 to be magnetically fixed, making the preheating of the cover more stable. After preheating and processing, the magnetic chuck 15 can be powered off during unloading, thus canceling its magnetism and facilitating unloading. This design uses existing technology to generate magnetic adsorption when powered on to fix the material tray, making processing more stable. After processing, the magnetic adsorption effect is canceled when the power is turned off, allowing the material tray to be removed for unloading.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
