School buses are used to transport students to and from schools, and school bus safety has always been a focus of public attention. In order to completely eliminate the hidden dangers of school buses, we must establish a sound legal and regulatory system and safety management system for school bus safety management. Clear priorities for school buses, strengthen supervision of school buses, and ensure the safety of school buses; and require schools to install satellite positioning and speed limit devices. Mainly starting from the following aspects.
I. Formulating a school bus safety management system
(1) Establish school police system. Every day, there is a school police officer on duty, responsible for the student's order and safety in the process of getting on and off the bus, crossing the road and driving. On-board police must carefully fill in the vehicle records.
(2) Formulate drivers' safe driving regulations.
(3) Strengthen violations and handling accidents.
(4) Formulate routine maintenance and repair regulations for automobiles.
II. Strengthening the consolidation and governance of road traffic around schools
(1) Use the police to maintain the traffic order around the school, strictly prevent the emergence of overloading, use of scrapped vehicles, illegal loading of passengers, etc., and strengthen publicity to improve students' safety awareness.
(2) The road traffic environment is also an important part of school bus safety. The investigation of school buses is stepped up, and the control of other vehicles on the road is increased. Strict punishments are imposed on illegal vehicles to increase the safety factor of school buses.
Third, in-depth propaganda, and actively create an atmosphere
(1) Actively promote the safety and civilized knowledge of school buses through publicity and drills, and remind parents to eliminate vehicles with potential safety hazards, and at the same time further improve students' awareness of traffic safety.
(2) At the same time, the people of the whole society are urged to abide by the traffic laws and create a harmonious and healthy traffic environment.
In short, to protect the safety of students going to and from school, besides eliminating the hidden dangers of school buses, we must all increase our safety awareness and jointly create a safe social atmosphere.
Hot Cutting Extrusion Pelletizer
LINA Extrusion Pelletizer
Most of the polymer must be kneaded and then granulated before it is made into a final product. Sorted by pelletizing ways, LINA rubber & plastic granulator can be divided into four categories: 1. Hot-cutting and air-cooling pelletizing method. 2. Under-water granulating method. 3. Water-strand extrusion method. 4. Water-ring granulation method. LINA pelletizer can meet the granulation needs of high-viscosity and low viscosity rubber and plastic materials, as well as some new materials and chemical additives.
LINA Die Surface Hot Cutting Pelletizing Machine
LINA`s die surface hot cutting and air cooling granulating machine is suitable for polymers that are sensitive to heat and long residence time, such as PVC, TPR, PE, cross-linked PE and so on. The flow path of the polymer from the extruder to the pelletizing port should be kept as short as possible with minimal heat. When polymer is extruded through the die surface, the rotating blade cuts the extruded materials into particles. After the pellets are cut, they are removed from the rotary blade and caught by cooling air circulating in the pelletizing room. The air stream preliminary cools the surface of the pellets and takes them out of the pelletizing room and sends them to the cooling zone.

Advantage of LINA Pelletizing Line
1. The unit has the whole unit process chain, sound and light failure alarm and fast lock fault point and other control functions. All parts that are in contact with the material are made of stainless steel.
2. High accuracy of temperature control system to ensure the temperature sensitivity of the material.
3. It adopts the drop type separating method after cutting process, to avoid Particle agglomeration and ensure particle cooling.
4. Feeding system of the pressing machine adopts heater and reversing device to solve problem of power outage, material crash and cleaning.
5. Especially, the barrel and die head adopts advanced foreign techniques to ensure and control the dangerous occurred when the pressure is uncontrollable. The honeycomb filter plate is easy to clean and quickly change the mesh and the die head t easy to leak.
6. The hoist adopts automatic return technology to ensure the working efficiency.
7. The technological combination of dual-pull forced feeder and single screw not only meet the high requirement of secondary continuous mixing, but also solve the problem of time and power consuming of traditional working process.
