Description

Technical Field

[0001] The utility model relates to the technical field of processing air-conditioner plastic parts, in particular to a feeding mechanism of an air-conditioner plastic part injection molding machine. Background Art

[0002] When the plastic parts on the air conditioner are produced by the injection molding machine, the plastic particles are conveyed to the hopper of the injection molding machine, and the plastic particles fall from the hopper to the screw conveyor rod. During the process of the screw conveyor rod conveying the plastic particles, the heating coil heats the plastic particles to melt them, and the melted raw materials are sent to the mold cavity of the mold in the injection molding machine, and then after cooling and shaping, the plastic parts on the air conditioner can be formed. In the production process of air-conditioning plastic parts, the hopper is the feeding mechanism of the injection molding machine, which is used to feed the injection molding machine. In order to prevent the moist plastic particles from directly entering the injection molding machine and causing pores or bubbles to appear on the surface of the air-conditioning plastic parts, the plastic particles in the hopper need to be dried by hot air drying. The hot air blower blows out hot air to make the hot air pass through the falling plastic particles, thereby achieving drying of the plastic particles.

[0003] After searching, the patent with publication number CN216732721U discloses a feeding device for plastic injection molding that can automatically feed materials, including a feeding barrel main body and a drying component. The top of the feeding barrel main body is provided with a feeding port, and the drying component used to dry the surface moisture of the material is arranged inside the feeding port. The drying component includes a mounting box, a heating plate, a blower, a connecting pipe, a ventilation slot, a first inner circular inclined plate and a second inner circular inclined plate. A heating plate is arranged inside the mounting box, and a blower is arranged below the heating plate. A connecting pipe is arranged at the output end of the blower. The feeding device for plastic injection molding that can automatically feed materials can heat the materials more evenly through the drying component, dry the moisture on the surface of the materials, avoid excessive moisture in the materials, and affect the quality of the finished products, thereby increasing the practicality of the device itself. The quantitative component can be used for automatic feeding, and the amount of feeding can be automatically controlled while ensuring the normal operation of the injection molding machine, thereby increasing the convenience of the device itself.

[0004] The above patent utilizes the cooperation of a blower, a heating plate, a first inner circular inclined plate and a second inner circular inclined plate to allow plastic particles to pass through the first inner circular inclined plate and the second inner circular inclined plate in sequence. The operation of the blower generates an airflow which is heated by the heating plate to form hot air, and the plastic particles are dried by hot air drying. However, in actual use, the moisture content of the plastic particles is different. When the water content of the plastic particles is high, the contact time between the plastic particles and the hot air is short, and it is difficult to effectively dry the plastic particles with a high water content. Therefore, the present application provides a feeding mechanism for an air-conditioning plastic parts injection molding machine to meet the needs. Utility Model Content

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, through the setting of the adjustment component, the servo on the adjustment component is used to adjust the inclination angle of the inclined plate.

[0029] like Figure 1-Figure 5 As shown, the embodiment of the utility model provides a feeding mechanism of an air conditioner plastic parts injection molding machine, including a hopper 1, and also including:

[0030] The drying component 2 includes an air outlet hood 23 fixed on the side of the hopper 1. The air inlet on the side of the air outlet hood 23 is connected to a hot air blower 22 through a pipeline. The pipeline is connected to the front side of the air outlet hood 23. The hot air blower 22 is powered by an external power supply. An air inlet slot and an air outlet slot are respectively provided on both sides of the hopper 1. A plurality of through holes are provided on the side of the air outlet hood 23 corresponding to the air inlet slot. The through holes are provided on the rear side of the air outlet hood 23. The hopper 1 is provided with a plurality of holes for The inclined plate 21 guides the plastic particles, and the inner wall of the air outlet slot is fixed with a wire mesh 25. The wet plastic particles enter the hopper 1 and fall down in sequence along the multiple inclined plates 21. The hot air blower 22 is started during the falling process. The hot air generated by the hot air blower 22 is sent into the air outlet cover 23 through the pipeline, and is sprayed from the through hole position of the air outlet cover 23 and blown to the falling plastic particles, so as to dry the plastic particles and prevent the plastic particles from generating bubbles or gas in the molten state, thereby ensuring the stable and reliable quality of the air conditioner plastic parts;

[0031] The adjusting component 3 includes a steering gear 31 fixed on the side of the hopper 1. The output end of the steering gear 31 movably passes through the hopper 1 and is fixedly connected to the side of the inclined plate 21. The steering gear 31 is used to drive the inclined plate 21 to rotate. The steering gear 31 drives the inclined plate 21 to rotate, changes the inclination angle of the inclined plate 21, and thus changes the falling speed of the plastic particles on the inclined plate 21 to adapt to the use of plastic particles with different humidity. When the water content of the plastic particles is low, the inclination angle of the inclined plate 21 is increased. When the inclination angle of the inclined plate 21 is too large, the inclined plate 21 has less obstruction to the falling of the plastic particles, thereby increasing the falling speed of the plastic particles, shortening the falling time of the plastic particles, thereby shortening the contact time with the hot air and the heating plate 27, and adapting to the use of plastic particles with low water content. When the inclination angle of the inclined plate 21 is small, the inclined plate 21 has greater obstruction to the falling of the plastic particles, thereby reducing the falling speed of the plastic particles, extending the falling time of the plastic particles, and increasing the contact time with the hot air and the heating plate 27, and adapting to the use of plastic particles with high water content.

[0032] like Figure 3 As shown, in this embodiment, a plurality of inclined plates 21 are staggered up and down, and the plastic particles slide down from the plurality of inclined plates 21 staggered up and down in sequence, and finally fall into the injection molding machine along the inner wall of the hopper 1. The falling time of the plastic particles is extended by the staggered up and down inclined plates 21, and the plastic particles are heated and dried by hot air drying during the falling process to prevent wet plastic particles from entering the injection molding machine.

[0033] like Figure 3 As shown, in this embodiment, a curved surface is provided on one side of the inclined plate 21 close to the inner wall side of the hopper 1, the left side of the left inclined plate 21 is a curved surface, and the right side of the right inclined plate 21 is a curved surface. Through the design of the curved surface, it is ensured that the side of the inclined plate 21 will not hinder the rotation of the inclined plate 21.

[0034] like Figure 4 As shown, in this embodiment, a wire mesh 24 is fixed to the inner wall of the air inlet slot, and the wire mesh 24 prevents plastic particles from entering the air outlet cover 23 from the through hole position.

[0035] like Figure 3 As shown, in this embodiment, a heating plate 27 is provided inside the inclined plate 21, and the heating plate 27 is used to heat and dry the plastic particles. During the hot air drying process of the plastic particles, the heating plate 27 heats and dries the plastic particles on the inclined plate 21 again, thereby improving the drying capacity of the plastic particles.

[0036] like Figure 3 As shown, in this embodiment, a convex strip 26 is fixed on the surface of the inclined plate 21. The convex strip 26 has a slight blocking effect on the falling of plastic particles, which can prolong the contact time between the plastic particles and the inclined plate 21, thereby further increasing the drying capacity of the plastic particles.

[0037] like Figure 3 As shown, in this embodiment, the surface of the convex strip 26 is provided with a curved surface, which prevents the plastic particles from remaining on the inclined plate 21 and ensures that the plastic particles on the inclined plate 21 will not accumulate.

[0038] like Figure 5 As shown, in this embodiment, an axle seat 32 is fixed to the side of the hopper 1, and a rotating shaft is fixed to the side of the inclined plate 21. The rotating shaft passes through the hopper 1 and is fixedly connected to the inner wall of the axle seat 32. The axle seat 32 is connected to the inclined plate 21 through the rotating shaft. The axle seat 32 is used to rotationally support the rear side of the inclined plate 21, so that the inclined plate 21 can rotate more smoothly.

[0039] like Figure 3 As shown, in this embodiment, the rotation angle range of the inclined plate 21 is from zero to fifteen degrees, and the rotation angle of the inclined plate 21 is adjustable, thereby changing the falling speed of the plastic particles on the inclined plate 21 to adapt to the use of plastic particles with different humidity.

[0040] Working principle: wet plastic particles enter the hopper 1 and fall down in sequence along a plurality of inclined plates 21 staggered up and down. During the falling process, the hot air blower 22 is started, and the hot air generated by the hot air blower 22 is sent into the air outlet hood 23 through a pipe, and is sprayed out from the through hole position of the air outlet hood 23 and blown to the falling plastic particles to achieve drying of the plastic particles. After the airflow passes through the plastic particles, it is discharged from the position of the wire mesh 25. When the plastic particles fall onto the inclined plate 21, the heating plate 27 in the inclined plate 21 is started to heat them again, thereby improving the drying effect of the plastic particles. The dried plastic particles then enter the injection molding machine for injection molding. The inclined plate 21 is fixed with a convex strip 26, which has a slight blocking effect on the falling of the plastic particles and can prolong the plastic particles. The contact time between the particles and the inclined plate 21 is increased, thereby further increasing the drying capacity of the plastic particles; the steering gear 31 is started, and the steering gear 31 drives the inclined plate 21 to rotate and adjust the inclination angle of the inclined plate 21. When the inclination angle of the inclined plate 21 is too large, the inclined plate 21 has less obstruction to the falling of the plastic particles, thereby increasing the falling speed of the plastic particles, shortening the falling time of the plastic particles, thereby shortening the contact time with the hot air and the heating plate 27, and adapting to the use of plastic particles with a lower water content. When the inclination angle of the inclined plate 21 is small, the inclined plate 21 has greater obstruction to the falling of the plastic particles, thereby reducing the falling speed of the plastic particles, extending the falling time of the plastic particles, and increasing the contact time with the hot air and the heating plate 27, and adapting to the use of plastic particles with a higher water content.

In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
