Description

Technical Field

[0001] The utility model relates to the technical field of production of microwave oven accessories, in particular to automatic feeding equipment for welding of microwave oven door hinges. Background Art

[0002] Microwaves are a type of electromagnetic wave. A microwave oven consists of a power supply, a magnetron, a control circuit, and a cooking chamber. The power supply provides a high voltage of about 4,000 volts to the magnetron, which, under the excitation of the power supply, continuously generates microwaves, which are then coupled into the cooking chamber through a waveguide system. There is a rotatable stirrer near the entrance of the cooking chamber. Because the stirrer is a fan-shaped metal, it can reflect microwaves in all directions after it is turned on, so it can evenly distribute microwave energy in the cooking chamber, thereby heating food. The power range of a microwave oven is generally 500 to 1,000 watts.

[0003] In the patent with patent number CN207807037U, an automatic feeding device and a hinge pressing system are disclosed. The automatic feeding device includes a feeding box, and an axis channel is formed in the feeding box. The length direction of the axis channel is the X-axis direction. The width of the axis channel is greater than the diameter of the axis and less than twice the diameter of the axis. The length of the axis channel is greater than the length of the axis. The axis channel is inclined in the up and down directions. The axis channel includes an upper opening for the axis to enter and a lower opening for the axis to discharge.

[0004] The above patent has the following problems:

[0005] When the shaft falls on the receiving device, there is a lack of limit on the shaft, and the shaft can easily slide into the groove by itself, resulting in the supply of excess shaft and poor reliability. Therefore, we have launched an automatic feeding equipment for microwave oven door hinge welding. Utility Model Content

[0006] The purpose of the utility model is to provide an automatic feeding device for welding microwave oven door hinges, which can not only automatically feed the hinge shaft, but also automatically provide a limit for the shaft to prevent the supply of excess shaft, and has good reliability, so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A microwave oven door hinge welding automatic feeding device comprises a material receiving device and an automatic feeding device, wherein a groove is provided on the upper side of the material receiving device, a support plate is fixedly provided on the side wall of the material receiving device, and the automatic feeding device comprises an axial channel, wherein the axial channel is fixedly arranged at the upper end of the support plate, a vertical push plate is slidably provided on the side of the axial channel outlet away from the groove, a cylinder is fixedly provided on the side of the support plate away from the groove, a piston rod end of the cylinder passes through the support plate and is fixedly connected to the push plate, and a limiting mechanism is provided on the side of the axial channel outlet close to the groove.
