Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of vacuum cup manufacturing, and particularly relates to a vacuum cup constant-temperature heating box. BACKGROUND

[0002] At present, in the metal vacuum cup industry, in order to detect the performance of the vacuum cup, a heating mode is adopted to detect the heat preservation effect. There are usually two traditional modes. Mode one of the traditional mode: hot water is placed in the cup, the outer wall of the cup is touched by hand, and the heat of the outer wall is felt to determine the heat preservation effect. The working environment of this mode is harsh, the safety is not high, the efficiency is low, and the operation is complex. Mode two of the traditional mode: a semi-automatic mode of hot air blowing in the cup, the outer wall of the cup is touched by hand, and the heat of the outer wall is felt to determine the heat preservation effect. The heating of this mode is unstable, which affects the measurement accuracy of the cup, and the heat source cannot be recycled, and the energy loss is large. SUMMARY

[0003] The utility model aims at overcoming the defects of the prior art, and provides a vacuum cup constant-temperature heating box, so that the temperature of the heat source is stable and adjustable.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] A vacuum cup constant-temperature heating box comprises a heating box and an electric control box. The heating box comprises a box body and a heating cover plate arranged on the top of the box body. A plurality of heating station openings for placing the vacuum cup are formed in the heating cover plate. An electric heating plate controlled by the electric control box is arranged on the inner bottom of the box body.

[0006] In the utility model, when the vacuum cup needs to be heated, the vacuum cup is placed in the heating station opening, and then the electric heating plate is started to heat by the electric control box. The heating temperature of the electric heating plate is controlled by the electric control box. In the utility model, the electric heating mode can make the temperature of the heat source stable and adjustable, ensure the stable heating temperature of the vacuum cup, improve the measurement accuracy, and the heating operation is convenient and fast.

[0007] Preferably, the electric heating plate is provided with a high-temperature Teflon cloth.

[0008] In the utility model, the high-temperature Teflon cloth is arranged on the upper surface of the electric heating plate, which can effectively protect the surface of the heating plate and reduce the influence of the vacuum cup workpiece on the heating plate.

[0009] Preferably, the electric heating plate is provided with a temperature sensor.

[0010] In the utility model, the temperature of the electric heating plate can be accurately obtained by the temperature sensor, and the temperature control data information of the electric control box is provided.

[0011] In this invention, there are various options for the temperature sensor. As a preferred option, the temperature sensor is a PT100 temperature sensor.

[0012] To facilitate the side-mounting of the thermos cup, this invention can provide a notch along the edge of the heating station opening. The notch can take various shapes. Preferably, the heating station opening has a V-shaped notch to facilitate the side-mounting of the thermos cup.

[0013] Preferably, the edge of the heating station port has a high-temperature resistant silicone seal.

[0014] The high-temperature resistant silicone seal in this invention can provide heat insulation while effectively protecting the surface of the thermos cup workpiece and preventing the heating station port from scratching the outer wall of the thermos cup.

[0015] There are multiple ways to fix the electric heating plate to the box body in this utility model. For ease of disassembly and assembly, the electric heating plate is preferably fixed to the bottom of the inner side of the box body with heat-insulating bolts.

[0016] Preferably, the bottom and sides of the box are provided with heat insulation cotton, the heating cover is a cover with a double-layer heat insulation structure, and there are 4 heating ports.

[0017] The heating cover plate in this invention can have various structural forms. To achieve heat insulation, a double-layer heat insulation structure can be set, and various existing heat insulation structures can be used. Furthermore, the number of heating station ports can be set according to requirements. In this invention, it can be set to four, and station port identification signs can be set at each heating station port. For example, when there are four ports, station port identification signs (A, B, C, D) can be laser-engraved. Additionally, heating chamber identification signs can also be set on the heating chamber body. For example, when there are multiple heating chambers in a testing workshop, they can be distinguished by heating chamber identification signs.

[0018] Preferably, the electrical control box is fixed to one side of the heating box, and a heat insulation pad is provided between the heating box and the electrical control box.

[0019] In this utility model, the electrical control box is installed on one side of the heating box and can be fixed with screws for easy disassembly and assembly. In addition, a heat insulation pad is set between the heating box and the electrical control box to prevent the temperature of the heating box from being conducted to the electrical control box, which would cause the temperature of the electrical control box to be too high and affect its operation.

[0020] The electrical control box of this utility model has various structural forms. Preferably, the side of the electrical control box adopts a honeycomb panel structure for convenient heat dissipation and power cable entry / exit wiring. The electrical control box is equipped with a switch with indicator lights, a thermostat, a voltage regulating module, and a fuse. The top of the electrical control box has a hinged cover for easy inspection and maintenance. The electrical control box of this utility model, equipped with a switch with indicator lights, a thermostat, a voltage regulating module, and a fuse, can precisely control the temperature of the control panel.

[0021] The advantages of this utility model compared with the prior art are:
