What are the safety precautions for blow molding processing?


Author: MULAN -Plastic Molding Manufacturer

(1) Formulate safe operation procedures for blow molding processing. When equipment or personal injury accidents occur, the carelessness of one person or group cannot be simply blamed. The management department must be foreseen and prepared for the safety of the operation, and have a quick response to unsafe situations. What is more important is to formulate and revise safe operation procedures in a timely manner, and the safety procedures must be enforced. (2) Prevent personal accidental injury. In order to prevent personal accidents, safety shields should be installed on the transmission parts of all machines; safety doors should be installed at the product demoulding outlet; safety and heat preservation shields should be installed in the heating area of ​​the machine; Protective devices inside the machine; emergency brake buttons and alarms should be installed on key parts of the equipment; hydraulic pressure tests should be carried out regularly on all pressure vessels. In the blow molding operation, if there are more than two people operating, the division of labor must be clearly defined; when loading and unloading equipment or molds, the power supply and air source should be cut off, and the repair station should be hung up.”sign; in the production of large containers, due to the large volume of the mold cavity, in order to prevent the human body from entering the mold cavity, a safety door should be installed, and the mold cannot be closed when the door is not closed and the personnel are not leaving the mold; Perform high-temperature operations such as welding and gas cutting near the head; when driving a cold car, the operator cannot stand under the machine head to prevent the overheated melt from splashing and hurting people; when performing material crushing operations, do not open the cover for maintenance without cutting off the power . (3) Safety protection of the machine. The machine should be installed with overload protection and safety protection devices. A simple overload protection device is to place a safety pin on the belt pulley. Once the transmission is abnormal and the safety pin breaks, the machine will stop the transmission. Constant temperature start protection device. Install a constant temperature starter on the blow molding machine. If the blow molding machine does not reach the set heating temperature, the blow molding machine cannot be started even if the start button is pressed. Blow molding machine safety explosion-proof device. The explosion-proof diaphragm of the device can withstand a certain range of melt pressure. The magnetic frame is installed in the hopper of the blow molding machine, and uses the magnetic field of the permanent magnet to prevent steel or metal debris from entering the blow molding machine.
