[0002] Hot melt equipment in PE material processing is mainly used to heat polyethylene (PE) materials to a specific temperature to soften them and make them fluid so that they can be molded, connected or processed. This equipment is usually used in the manufacturing process of PE pipes, pipe fittings, films, sheets and other products. PE materials need to be properly heated during processing to achieve the ideal plastic state in order to perform various processing operations such as extrusion, injection molding, hot melt connection, etc.

[0003] The hot melt equipment usually includes a hot melter that can heat the hot melt material. Generally, hot melt materials such as plastic particles are added to the hot melter through a feeding structure, and then discharged from the discharging structure after being melted by the hot melter. However, the temperature in the hot melter will change with factors such as the material properties of the hot melt material, the heating power, and the pressure change in the hot melter. When the temperature in the hot melter is high, the feeding speed can be appropriately increased to maintain a certain production efficiency; when the temperature in the hot melter is low, the feeding speed can be appropriately reduced to avoid poor product shape. The existing hot melt equipment is not convenient to automatically and synchronously adjust the feeding speed according to the temperature in the hot melter, so it needs to be improved.

The diameter of the adjustment hole 19 is the same as that of the material dispersing hole 14, and the number is equal.

[0019] By providing the temperature sensor 12, the temperature change in the hot melter 2 can be monitored in real time, and the motor 21 can be adjusted to automatically control the sliding plate 20 to slide accordingly, so as to adjust the size of the material discharging hole 14, thereby adjusting the feeding speed accordingly.

[0020] A screw rod 22 fixedly connected to the output shaft of the adjusting motor 21 is rotatably arranged in the adjusting box 16, and a moving block 23 is threadedly connected to the screw rod 22; a connecting tube 24 and a connecting block 25 are fixedly connected to one side of the moving block 23 in sequence, and the connecting block 25 is fixedly connected to the sliding plate 20. The inner wall section of the adjusting box 16 is square, and the moving block 23 is a square corresponding to the inner wall of the adjusting box 16, and the moving block 23 and the inner wall of the adjusting box 16 are in contact with each other.

[0021] The cooperation between the inner wall of the square adjustment box 16 and the moving block 23 can limit the rotation of the moving block 23, thereby converting the rotation of the screw rod 22 into the movement of the moving block 23, and transmitting the movement to the sliding plate 20 through the connecting tube 24 and the connecting block 25.

[0022] The end cover 3 is provided with a rotating motor 4 , the output shaft of which is fixedly connected with a rotating shaft 15 located in the bulk material barrel 13 , and the rotating shaft 15 is fixedly provided with a scraping plate 17 corresponding to the bottom of the bulk material barrel 13 .

[0023] The rotating motor 4 drives the scraper plate 17 to scrape the bottom of the bulk barrel 13, which can promote the movement of plastic particles and prevent the plastic particles from accumulating and clogging the position of the material discharging hole 14, thereby ensuring normal feeding.

[0024] Principle of the utility model

[0025] like Figure 1-2 As shown, when the utility model is used, plastic particles are added into the bulk material barrel 13 through the feed pipe 5, and the rotating motor 4 is started to drive the scraper plate 17 to move in the bulk material barrel 13, thereby pushing the plastic particles into the hot melter 2 from the discharge hole 14 and the adjustment hole 19, and the heating structure 8 can heat the plastic particles. At the same time, the stirring motor 11 drives the stirring blade 9 to rotate to stir the plastic particles in the hot melter 2.

[0026] The temperature sensor 12 can monitor the temperature in the hot melt 2 in real time and transmit the monitoring result to the controller 6; when the temperature in the hot melt 2 is high, the controller 6 controls the regulating motor 21 to work, such as Figure 4 As shown, the sliding plate 20 is driven by the moving block 23 to slide in the chute 18, increasing the overlap area of ​​the adjustment hole 19 and the material discharging hole 14. At this time, more plastic particles can enter the hot melter 2 per unit time, thereby appropriately increasing the feeding speed. When the temperature in the hot melter 2 is low, the regulating motor 21 is reversed to reduce the overlap area of ​​the regulating hole 19 and the material discharging hole 14, thereby reducing the feeding speed. Therefore, the present application can monitor the temperature change in the hot melter 2 in real time, and automatically control the corresponding sliding of the sliding plate 20 by adjusting the motor 21 to adjust the size of the material discharging hole 14, thereby adjusting the feeding speed accordingly.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
