Description

Technical Field

[0001] The utility model relates to the technical field of acoustic bag production equipment, in particular to an oven device for acoustic bag production. Background Art

[0002] At present, the noise of motors usually causes a lot of troubles. For example, the motors of vehicles will seriously affect the riding experience of passengers. Therefore, the noise of motors is a major problem that needs to be solved in the production and testing of motors. Because the noise of the motors can only be tested after the product assembly is completed during the testing and development process, this will shorten the working time of subsequent optimization and waste a lot of mold development costs. Therefore, the existing technology controls the noise of the motors during the motor design stage. Common methods include harmonic injection, adding acoustic packages, changing the motor electromagnetic scheme, and vehicle path optimization. Among them, acoustic packages are more widely used due to their low cost and simple operation.

[0003] The existing production method of acoustic packages is usually to heat and soften the material and then use a stamping device to stamp it into an upper part and a lower part with a receiving cavity, and then perform processes such as trimming, and then connect and fix the upper and lower parts after placing the motor. Among them, the material is usually heated by using a heating mechanism to bake the sheet to soften its texture for easy molding. Ordinary heating mechanisms have poor airtightness and poor heat preservation during heating, which easily leads to waste of heating efficiency and insufficient heating of the sheet. If you want to ensure heating efficiency and heating sufficiency, you usually consider a closed oven structure. Conventional ovens generally use manual picking and placing of materials, which is inefficient and has high labor costs. If automated equipment is used to replace manual operation, it is necessary to ensure that the material can automatically enter and exit the oven without interfering with the oven. The existing oven structure cannot solve this problem.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a new technical solution. Utility Model Content
