A high temperature heating plate mechanism

Abstract

The utility model discloses a high-temperature heating plate mechanism, which relates to the field of heating technology. The mechanism is composed of a heating plate made of ceramic material, a heating tube, a thermocouple and a heat-insulating cover plate. When the heating plate is manufactured, a slot in the shape of a spiral line is integrally formed on its lower surface, and the distance between each turn of the spiral line is equal, and heating tubes of the same shape are installed in the slot. The high-temperature heating plate mechanism is achieved by embedding a small-diameter heating tube into an equidistant spiral line-shaped slot of a ceramic disc, and then sealing the lower layer with a heat-insulating circular plate. The heating tube is coiled around the heating plate in this way, so that the contact surface value between the heating plate and the heating tube is relatively large and uniform. Therefore, the heating plate of this structure is heated more evenly and has a higher heating efficiency.

Description

Technical Field

[0001] The utility model relates to the technical field of heating, in particular to a high-temperature heating disc mechanism. Background Art

[0002] The prior art discloses a ceramic disc heating device (CN116456516A), which adopts a structural design in which a graphene heating wire is placed between two layers of circular ceramic plates. The upper ceramic plate is also dug with a vacuum air guide groove for placing conductive materials at each product position on the entire disc.

[0003] However, the heating plate of the above-mentioned heating mechanism has only a few short heating rods, and the heating plate is not heated evenly, which may easily cause a large difference in temperature of the products at different positions on the material plate. In addition, since the products cannot actually fit tightly to the bottom of the material acupuncture point plate and are affected by heat convection, the negative pressure of the vacuum air guide groove will continue to absorb and take away the heat of the products, resulting in low and unstable temperature of the products.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model provides a technical solution: a high-temperature heating plate mechanism, which is composed of a heating plate 1 made of ceramic material, a heating tube 2, a thermocouple 3 and a heat-insulating cover plate 4. When the heating plate 1 is manufactured, a card slot 11 in the shape of a spiral line is integrally formed on its lower surface, and the distance between each turn of the spiral line is equal. The heating tube 2 of the same shape is installed in the card slot 11, so that the contact area between the heating plate 1 and the heating tube 2 can be relatively large and uniform. Therefore, the high-temperature heating plate mechanism of this embodiment, The heating is more uniform and the heating efficiency is higher; a threaded hole 15 is also reserved on the lower surface of the heating plate 1, and the thermocouple 3 selected in this embodiment is a threaded thermocouple. When installing the thermocouple 3, the thermocouple 3 can be directly screwed into the threaded hole 15 using a thread, so that the detection end of the thermocouple 3 will contact the heating plate 1 to detect the heating temperature of the heating plate 1. The heat-insulating cover plate 4 is installed on the lower part of the heating plate 1 by bolts, which can not only play a role in heat preservation, but also prevent excessive temperature from being transmitted to the following structure and causing damage.

[0026] In order to facilitate the installation of the mechanism into the device, a through hole 12 and a through hole 2 41 are respectively penetrated in the middle of the heating plate 1 and the insulation cover plate 4. In addition, in order to facilitate the power connection end of the heating tube 2 to be led out from the mechanism, a through hole 3 42 connected to the through hole 2 41 is reserved on the insulation cover plate 4. After the thermocouple 3 is installed, the tail end will protrude from the heating plate 1, so in order to make the insulation cover plate 4 adaptable, a through hole 4 43 is also reserved on the insulation cover plate 4.

[0027] Finally, six air holes 13 and six air holes 2 14 are respectively opened on the upper and lower surfaces of the heating plate 1. The air hole 13 is an oblong structure, and the air hole 2 14 is a circular structure, and the two are connected. The purpose of setting the air hole 13 and the air hole 2 14 is that the air holes with negative pressure can help the suction nozzle to discharge the material smoothly. After the heating is completed, the air holes are blown by the blowing device to make the product separate from the upper surface of the hole of the material plate, and the suction nozzle can quickly take away the heated product. This structure has air holes only at the material taking position, which not only ensures that the suction nozzle takes and discharges the material smoothly and efficiently, but also effectively reduces the influence of the negative pressure taking away the heat (arranging air holes is a well-known technology in the field and will not be described in detail here).
