The device includes a housing with feeding pipes connected to both sides of the top of the housing. A screening mechanism is installed at the top of the feeding pipes. Heating mechanisms are installed on both sides of the housing. A temperature sensor is installed through the top of the housing. A support frame is installed at the bottom of the housing, and an adjustment mechanism is installed at the bottom of the support frame. This invention, through the cooperation of a limiting sliding hole, a mounting slide cylinder, a screening frame, a fixing plate, an electric push rod, and a connecting plate, can screen materials, preventing impurities from entering the equipment during material addition. The cooperation of a first motor, a stirring shaft, a heater, and a heat-conducting plate can heat the materials, preventing solidification during storage and thus increasing the practicality of the equipment.

[0004] An investigation revealed that existing injection molding equipment uses granular raw materials. However, plastic granules vary in size, and larger granules melt more slowly, ultimately leading to a decrease in the quality of products produced in the injection molding equipment. Furthermore, the screening plates are easily clogged by larger plastic granules during use, affecting the processing.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0021] Please see Figure 1-5 A material feeding structure includes a processing cabinet 1, with a feed end 11 fixedly connected to the upper end of the processing cabinet 1 and a discharge end 12 fixedly connected to the lower end of the processing cabinet 1; a feeding assembly, which is disposed inside the processing cabinet 1 and is used to supply raw materials. The feeding assembly includes a limiting frame 3, a movable frame 31, cleaning blocks 41, and a micro motor 5. The limiting frame 3 is fixedly connected to the inner wall of the processing cabinet 1, the movable frame 31 is elastically connected to the limiting frame 3, the micro motor 5 is symmetrically disposed on the limiting frame 3, and the micro motor 5 is driven by the movable frame 31. The cleaning blocks 41 are arranged in an array inside the processing cabinet 1. Raw materials are fed into the processing cabinet 1 through the feeding end 11. The raw materials fall into the movable frame 31. The micro motor 5 drives the movable frame 31 to continuously lift and lower through the working transmission and the cooperation of the elastic setting. The vibration force generated by the lifting and lowering screens the raw materials and sends the plastic raw materials of suitable particle size to the discharge end 12 for subsequent processing. During the lifting and lowering, the movable frame 31 intermittently contacts the cleaning block 41. The cleaning block 41 pushes out the blocked plastic raw materials through the holes on the movable frame 31 to avoid blockage and affect subsequent processing.

[0022] Among them, a spring 32 is arranged around the limiting frame 3 and the movable frame 31. The end of each spring 32 is fixedly connected to the limiting frame 3 and the movable frame 31 respectively. A filter plate 33 is fixedly connected to the bottom of the movable frame 31. The movable frame 31 is slidably connected to the limiting frame 3 and the processing cabinet 1. Each micro motor 5 is fixedly connected to the limiting frame 3. The output end of each micro motor 5 and the coupling are connected to a turntable 51. A driving rod 52 is fixedly connected to the edge of each turntable 51. A fixed rod 54 is fixedly connected to the bottom of the movable frame 31. A transmission belt 53 is arranged between the corresponding fixed rod 54 and the driving rod 52. The end of the transmission belt 53 is sleeved with the corresponding driving rod 52 and the fixed rod 54 respectively. Mounting strips 4 are symmetrically arranged inside the processing cabinet 1. Each mounting strip 4 is fixedly connected to the inner wall of the processing cabinet 1. Cleaning blocks 41 are arranged in an array between the mounting strips 4. Each cleaning block 41 is fixedly connected to the corresponding mounting strip 4. The micro motor 5 drives the turntable 51 to rotate through the output end and coupling. As the turntable 51 rotates, it drives the driving rod 52 to pull the transmission belt 53 downward. The transmission belt 53 pulls the fixed rod 54 at the other end. The fixed rod 54 drives the movable frame 31 to slide in the limiting frame 3. As the movable frame 31 slides, the spring 32 is compressed. The spring 32 deforms and applies the deformation force to the movable frame 31. As the micro motor 5 and the turntable 51 intermittently pull the movable frame 31, the deformation of the spring 32 is applied to realize the reset of the movable frame 31 and the filter plate 33, thereby performing continuous lifting and lowering. During the lifting and lowering, the plastic raw materials are screened. The movable frame 31 and the filter plate 33 are set to select suitable raw materials, avoiding the slow melting speed of large particles, which ultimately leads to a decrease in the quality of the products produced in the injection molding equipment. As the movable frame 31 continues to rise and fall, it drives the filter plate 33 to rise and fall. The screening holes on the filter plate 33 intermittently contact the cleaning block 41. Through the setting of the cleaning block 41, the raw material blocked in the holes of the filter plate 33 is pushed out, so as to avoid the raw material from continuously accumulating on the filter plate 33 and affecting the subsequent screening and processing. It is worth noting that the upper part of the processing cabinet 1 can be disassembled, which facilitates the subsequent cleaning of the movable rack 31; It is worth noting that the micro motor 5 includes a bottom cover, a receiving base, a housing mounted on the receiving base, a support frame mounted inside the housing, four permanent magnets and a coil mounted on the support frame, an output shaft mounted on the receiving base and extending outside the housing, and an iron core mounted on the output shaft. Each pair of permanent magnets is symmetrically located on the side of the support frame, and the angle formed by the line connecting the centers of the two permanent magnets on the same side of the support frame and the axis of the output shaft is 50° to 60°. The iron core includes a sleeve portion fitted onto the output shaft and swing arms symmetrically arranged on both sides of the sleeve portion, with the swing arms opposite to the permanent magnets. In this micro DC motor, the permanent magnets generate a large auxiliary force, have sufficient force travel, and a large swing amplitude. During the gap in current direction change, it is not necessary to use a return spring to compensate for insufficient power during circuit switching, nor is it necessary to use a current commutator to determine the current direction. The structure is simple and the noise is low. The micro motor 5 has already been fully disclosed in the prior art CN107394982B micro DC motor and will not be described in detail here.

[0023] The bottom of the limiting frame 3 is symmetrically provided with guide covers 23. Each guide cover 23 is fixedly connected to the inner wall of the processing cabinet 1. Each guide cover 23 is provided with a heating module 24 at its bottom. The heating module 24 is fixedly connected to the inner wall of the processing cabinet 1 and fits against the bottom of the guide cover 23.

[0024] The processing cabinet 1 is fixedly connected to a drive motor 2, and a crushing roller 21 is arranged between the bottom of the guide cover 23. The crushing roller 21 is rotatably connected to the inner wall of the processing cabinet 1. The output end of the drive motor 2 is fixedly connected to the crushing roller 21 through a coupling. Scrapers 22 are arranged around the crushing roller 21, and each scraper 22 is fixedly connected to the crushing roller 21. The screened raw materials are guided by the guide cover 23, and then the drive motor 2 drives the crushing roller 21 through the output end and the coupling. The crushing roller 21 crushes the screened raw materials as it rotates, making the raw materials finely crushed, which is convenient for subsequent melting and processing. In addition, the crushing roller 21 drives the scraper 22 to contact the wall surface of the guide cover 23, and friction is achieved during rotation to remove the raw materials adhering to the wall surface of the guide cover 23, so as to avoid the impact on the quality of subsequent processing due to different types of raw materials. Furthermore, the heating module 24 continuously heats the bottom of the guide cover 23, preheating the raw material through the heating of the heating module 24. The preheated raw material has a certain amount of heat, which shortens the processing time required for melting in the subsequent melting process.

[0025] An injection molding machine comprising all of the above-mentioned feeder structures; Raw materials are fed into the processing cabinet 1 through the feeding end 11. The raw materials fall into the movable frame 31. The micro motor 5 drives the movable frame 31 to continuously lift and lower through the working transmission and the cooperation of the elastic setting. The vibration force generated by the lifting and lowering screens the raw materials and sends the plastic raw materials of suitable particle size to the discharge end 12 for subsequent processing. During the lifting and lowering, the movable frame 31 intermittently contacts the cleaning block 41. The cleaning block 41 pushes out the blocked plastic raw materials through the holes on the movable frame 31 to avoid blockage and affect subsequent processing.

[0026] Working principle: Raw materials are fed into the processing cabinet 1 through the feed end 11. The raw materials fall into the movable frame 31. The micro motor 5 drives the movable frame 31 to continuously lift and lower through the working transmission and the cooperation of the elastic setting. The vibration force generated by the lifting and lowering screens the raw materials, and sends the plastic raw materials of suitable particle size to the discharge end 12 for subsequent processing. During the lifting and lowering, the movable frame 31 intermittently contacts the cleaning block 41. The cleaning block 41 pushes out the plastic raw materials that are blocked by the holes on the movable frame 31, so as to avoid blockage and affect subsequent processing. The micro motor 5 drives the turntable 5 through the output end and coupling. 1. Rotation: As turntable 51 rotates, it drives drive rod 52 to pull transmission belt 53 downward. Transmission belt 53 pulls fixed rod 54 at the other end. Fixed rod 54 drives movable frame 31 to slide within limiting frame 3. During the sliding of movable frame 31, spring 32 is compressed, causing deformation and applying the deformation force to movable frame 31. Through the deformation of spring 32, the movable frame 31 and filter plate 33 are reset by the intermittent pulling of micro motor 5 and turntable 51, thus achieving continuous lifting and lowering. During the lifting and lowering, plastic raw materials are screened. The arrangement of movable frame 31 and filter plate 33 is used to screen the plastic raw materials. Appropriate raw materials are selected to avoid slow melting of large particles, which could lead to a decline in product quality during injection molding. As the movable frame 31 continuously rises and falls, it drives the filter plate 33 to rise and fall as well. The screening holes on the filter plate 33 intermittently contact the cleaning block 41. The cleaning block 41 pushes out raw materials clogging the holes in the filter plate 33, preventing continuous accumulation and impact on subsequent screening processes. The guide cover 23 guides the screened raw materials, and then the drive motor 2, through its output end and coupling, drives the crushing roller 21. The crushing roller 21 crushes the screened raw materials as it rotates, making them finely pulverized to facilitate subsequent melting processing. The rotation of the crushing roller 21 also causes the scraper 22 to contact the wall of the guide cover 23, generating friction to remove any raw materials adhering to the wall of the guide cover 23, thus preventing quality issues caused by different types of raw materials in subsequent processing. Furthermore, the heating module 24 continuously heats the bottom of the guide cover 23, preheating the raw materials. This preheated material possesses sufficient heat to shorten the melting processing time required in subsequent melting processes.
