Manufacturing method of clutch mechanism for automatic production of dipped gloves

- Oct 07, 2020-

Background technique:


The establishment and development of the labor protection products industry was established and developed following the establishment of my country's socialist system and the development of industry and agriculture. Reform and development have promoted the overall development of China's labor protection products industry.


In the process of producing labor protection gloves, it mainly includes preheating, dipping, primary drying, desalination, immersion, secondary drying, and vulcanization processes. Among them, the dipping process is divided into impregnation with impregnation agent, rubber dipping and anti-slip Salt immersion treatment.


In the known continuous labor protection glove production line, the passive dipping scheme is mainly adopted. For example, the mold bar and the multiple hand molds installed on the mold bar are passed through and temporarily stayed in the corresponding section of the dipping process through a chain conveyor line, that is, dipping The anti-seepage agent pool and rubber pool in the process are actively raised from the anti-seepage agent pool and rubber pool, so that the gloves outside the hand mold come into contact with the materials in the anti-seepage agent pool and rubber pool. After the immersion is completed, they will actively descend to facilitate the gloves. Pass smoothly; in this way, due to the large volume and heavy weight of the anti-seepage agent pool and the rubber pool, frequent lifting and lowering causes high energy consumption, high failure rate, and certain potential safety hazards.


At present, there is also an active impregnation concept. In this scheme, when the mold rod passes through the impregnation section, the power device drives the mold rod and the hand mold on it to approach the impermeable agent pool, which does not require the impregnant pool to rise to achieve impregnation. , Which greatly improves work stability. The disadvantage of this solution is that the solution adopts a follow-up drive, that is, an additional power device is arranged on the mold rod and moves with the mold rod. It is necessary to consider the mobile supply of its power source, such as power supply and air supply, which is obviously inconvenient.
