[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, an injection molding feeding device for automotive plastic parts includes a housing body 1. A first motor 101 is fixedly connected to the side of the housing body 1. A feed pipe 109 is connected through the surface of the housing body 1. A conveying housing 105 is fixedly connected to the end of the feed pipe 109. A second motor 106 is fixedly connected to the side wall of the conveying housing 105. A conveyor belt 107 is provided inside the conveying housing 105. A long rod 108 is fixedly connected to the inner wall of the conveying housing 105. During operation, the first motor 101 and the second motor 106 are started. The first motor 101 drives the components inside the housing body 1 to rotate, and the second motor 106 drives the conveyor belt 107 to convey the components. The raw material is introduced onto the surface of the conveyor belt 107 and moves with it. When the conveyor belt 107 moves to the long rod 108, the accumulated raw material is smoothed out by the height limit of the long rod 108, preventing the raw material from accumulating on the surface of the conveyor belt 107. As the conveyor belt 107 moves to the top of the discharge pipe 109, the raw material falls into the outer shell 1. With the rotation of the internal components of the outer shell 1, the raw material is pushed forward and finally moves to the output end of the outer shell 1, from which it is ejected. Thus, during the conveying of raw materials, the device will not be blocked due to excessive accumulation of raw materials, thus saving time on cleaning.

[0026] like Figure 2 As shown, grooves 2 are provided on both sides of the feed pipe 109; heating rods 201 are installed in the grooves 2; multiple heating rods 201 are provided; during operation, when the raw material is fed into the feed pipe 109 by the conveyor belt 107 and falls into the outer shell body 1, the raw material will be heated by the multiple heating rods 201 in the grooves 2, thereby drying the wet material; thus, drying the raw material during the injection molding process of automotive plastic parts can improve product quality and processing stability by reducing moisture content, protect equipment life and reduce losses and energy consumption.

[0027] like Figures 1 to 4 As shown, a dust cover 3 is installed at the end of the conveyor housing 105; a feed inlet 301 is connected through the surface of the dust cover 3; during operation, raw materials are poured into the conveyor belt 107 through the feed inlet 301. When the raw materials are poured in, a large amount of dust is generated. During the conveying process, the dust cover 3 will block the generated dust inside the conveyor housing 105, so that the dust will not spread in the air; thereby reducing the spread of dust in the work area, improving the air quality in the work area, and improving the working environment.

[0028] like Figures 1 to 4As shown, a dust suction pipe 4 is connected through the side wall of the conveying housing 105; an air inlet 401 is provided on the surface of the dust cover 3; during operation, after connecting the dust suction pipe 4 to the dust suction device, the dust suction device is started, and suction is generated from the dust suction pipe 4, air is introduced into the air inlet 401, and then the raw material is poured in through the feed port 301. At this time, the dust generated inside the conveying housing 105 will be sucked out from the dust suction pipe 4 by the suction of the dust suction device, reducing the amount of dust inside the conveying housing 105 falling onto the raw material and into the housing body 1. Therefore, when there is too much dust generated by the raw material, it is not necessary to clean the conveying housing 105; thereby, the risk of dust explosion and equipment fire can be eliminated, the raw material can be prevented from being contaminated to improve the product qualification rate, the accuracy of process parameters can be ensured, the equipment maintenance cost can be reduced, the pressure of excessive dust in the environment can be reduced, and the workshop working environment can be improved.

[0029] like Figure 5 As shown, a magnet 5 is fixed to the inner wall of the dust cover 3; multiple magnets 5 are provided; during operation, when the raw material moves on the conveyor belt 107 and is fed into the outer shell 1, due to the presence of magnetic substances in the raw material, the raw material will be attracted by multiple magnets 5 on the inner wall of the dust cover 3 as it moves on the conveyor belt 107. When too much magnetic substance is attracted by the magnets 5, the magnets 5 can be cleaned by opening the dust cover 3 with the handle; thereby attracting magnetic substances in the injection molding raw material of automotive plastic parts, it can eliminate appearance defects and functional hazards caused by metal impurities in the product, ensure the consistency of material performance, reduce wear of key components, reduce the frequency of equipment downtime, extend the service life of the mold and reduce maintenance costs, and the magnets 5 can be cleaned by opening the dust cover 3, so that the magnets 5 can be recycled.

[0030] like Figure 1 and Figure 5 As shown, a baffle 6 is rotatably connected inside the feed inlet 301. During operation, the rotatable connection between the feed inlet 301 and the baffle 6 is achieved through a torsion spring. Thus, after the raw material is poured through the feed inlet 301, the baffle 6 will reset and close the feed inlet 301. Therefore, the baffle 6 will reset after the raw material is poured, which will block the dust generated when the raw material is poured into the conveying housing 105 and prevent it from drifting away with the opening of the feed inlet 301. It can also prevent the entry of foreign objects such as insects.

[0031] Working principle: By starting the first motor 101 and the second motor 106, the first motor 101 drives the components inside the outer casing 1 to rotate, and the second motor 106 drives the conveyor belt 107 to transport materials. When raw materials are introduced onto the surface of the conveyor belt 107, they move along with it. When the conveyor belt 107 reaches the long rod 108, any accumulated material is smoothed out by the height limit set by the long rod 108, preventing material buildup on the surface of the conveyor belt 107. The material falls from above the discharge pipe 109 into the outer casing 1. As the internal components of the outer casing 1 rotate, the material is propelled forward, eventually reaching the output end of the outer casing 1 and being ejected from it. When the raw material is fed into the discharge pipe 109 via the conveyor belt 107 and falls into the outer casing 1, it is heated by multiple heating rods 201 within the groove 2, thus drying the wet material. The raw material is then poured onto the conveyor belt 107 through the feed inlet 301. During this pouring process, a large amount of dust is generated, which is then discharged during the conveying process. During the process, the dust cover 3 will block the generated dust inside the conveyor housing 105, preventing the dust from spreading in the air. After connecting the suction pipe 4 to the vacuum cleaner, the vacuum cleaner is started, and suction is generated from the suction pipe 4, air is drawn in through the air inlet 401, and then the raw material is poured in through the feed inlet 301. At this time, the dust generated inside the conveyor housing 105 will be sucked out from the suction pipe 4 by the suction of the vacuum cleaner, reducing the amount of dust inside the conveyor housing 105 falling onto the raw material and into the housing body 1. Therefore, if there is too much dust generated by the raw material, it is not necessary to... The conveyor housing 105 needs to be cleaned. When the raw material moves on the conveyor belt 107 and is fed into the housing body 1, it will be attracted by multiple magnets 5 on the inner wall of the dust cover 3 due to the presence of magnetic substances in the raw material. When the magnets 5 are attracted by too much magnetic substances, the magnets 5 can be cleaned by opening the dust cover 3 with the handle. The rotational connection between the feed inlet 301 and the baffle 6 is connected by a torsion spring. Thus, after the raw material is poured out through the feed inlet 301, the baffle 6 will reset and close the feed inlet 301.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
