[0002] Halogen-free flame retardant particles are a type of plastic particles specially designed to improve the flame retardant properties of materials. These particles do not release halogen elements (such as chlorine, bromine, etc.) when burned, thereby reducing the generation of harmful gases and smoke; halogen-free flame retardant particles are widely used in electronics, electrical appliances, building materials, and transportation, meeting high requirements for environmental protection and safety.

[0003] During the production, the halogen-free flame retardant particles are extruded from the extruder die head through the melt blended materials to form continuous molten strips; the strips are cooled by a cooling water tank or an air cooling system to solidify; the cooled strips are cut into uniform particles by a pelletizer, and these particles are the final halogen-free flame retardant particles. Therefore, during the production process, the strips may break. If the breakage of the strips is not discovered in time, part of the material that has not been extruded in time may degrade, especially some sensitive polymer materials exposed to high temperature for too long, which will affect the performance of the material, increase waste and poor practicality; therefore, in order to solve the above problems, a broken strip alarm device is proposed.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

On both sides of the limiting wheel 3, when producing halogen-free flame retardant particles, the material needs to be melted into strips first, and the strips need to be transported to the cutting equipment to be cut into halogen-free flame retardant particles. Before cutting, the strips are transported through the transmission mechanism, and the strips can be placed on the pressure sensor 4 in the first limiting wheel 3 and transported to the cutting equipment. If the strip is broken, the strip will not continue to be placed on the pressure sensor 4. The pressure sensor 4 will start the alarm light 7, and the alarm light 7 will remind the staff that the strip material is broken, so that the staff can stop the transmission mechanism in time through the stop button 8, so that the staff can deal with the broken strip in time, thereby reducing the generation of waste.

[0021] In one aspect of the present embodiment, after the material is melted into a strip, the spraying structure can be used to spray water to cool the strip. After cooling, the strip will rest on the rubber ring 15 provided in the second limiting wheel 14, and the motor 11 fixedly installed in the mounting groove 9 by the fixing rod 10 is started. The reducer 12 is also fixedly installed in the mounting groove 9. Through the coordination of the motor 11 and the reducer 12, the rotating shaft 13 can rotate slowly, thereby driving the second limiting wheel 14 to rotate to transport the strip. Through the coordination of the rubber ring 15 and the texture groove 16, the friction of the strip can be increased, so that the strip can be better transported and processed.

[0022] In one aspect of the present embodiment, when the height of the mounting frame 1 needs to be adjusted, the first electric push rod 19 fixedly installed in the setting groove 18 can be started to drive the adjusting rod 20 to slide in the setting groove 18, so that the adjusting rod 20 and the supporting leg 17 can be telescoped, thereby adjusting the height of the mounting frame 1, so that the mounting frame 1 can be adjusted to a suitable height to set a broken strip alarm for the strips melted from the material. When the device needs to be moved a short distance or adjusted in direction, the second electric push rod 22 can be started to drive the universal wheel 23 to move out of the hidden groove 21 and lift the supporting leg 17, so that the mounting frame 1 can be pushed or the mounting frame 1 can be rotated to move the device a short distance or adjust the direction, making the device more convenient when moving a short distance or adjusting the direction.

[0023] In one aspect of the present embodiment, when the material is melted into a strip, there will be a certain temperature, and a spraying structure can be used to spray water to physically cool down the strip. The spraying structure can be installed on the upper side of the mounting frame 1, so that the sprayed water can be collected by the mounting frame 1. When the collected water needs to be transported away, the valve 25 can be opened to allow the collected water to flow out through the guide pipe 24. The water used to physically cool the strip can be collected and recycled, thereby reducing the waste of resources.

[0024] Working principle of the utility model: when the broken strip alarm device is in use, after the material is melted into a strip, the spray structure can spray water to cool the strip. After cooling, the strip will be placed on the rubber ring 15 set in the second limiting wheel 14, and the motor 11 fixedly installed in the mounting groove 9 through the fixing rod 10 is started. The reducer 12 is also fixedly installed in the mounting groove 9. Through the arrangement of the motor 11 and the reducer 12, the rotating shaft 13 can be rotated slowly, thereby driving the second limiting wheel 14 to rotate to transport the strip. At the same time, when the strip is transported, the strip will also be placed on The pressure sensor 4 in the first limiting wheel 3 makes the pressure sensor 4 contact with the strip, and when the strip is conveyed, the first limiting wheel 3 will slide outside the fixed shaft 2. If the strip is broken, the strip will not continue to be placed on the pressure sensor 4 and contact the pressure sensor 4. The pressure sensor 4 will start the alarm light 7, and the alarm light 7 will remind the staff that the strip material is broken, so that the staff can stop the motor 11 in time through the stop button 8, so that the broken material can be dealt with in time. In this solution, all electrical equipment is powered by an external power supply.
