Detailed Implementation

[0025] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] like Figures 1 to 3 As shown, this utility model proposes an automatic plastic granule feeding machine, including: a bracket 1, a support base 2, a stirring device 3, a conveying device 4, a drive motor 5, a filtering mechanism 6, and a recycling device 7; the stirring device 3 is installed on the upper end of the support base 2, and the conveying device 4 is provided below the stirring device 3. The angle between the output direction of the conveying device 4 and the horizontal plane is an acute angle. The upper end of the conveying device 4 is supported by the bracket 1, and the lower end of the conveying device 4 is connected to the bottom output end of the stirring device 3. The output end of the drive motor 5 is connected to the conveying device 4; the bracket 1 has a filtering mechanism 6 at the end opposite to the conveying device 4. The filtering mechanism 6 includes: a... The mounting base 61 and filter screen 62 are provided. One side of the mounting base 61 is connected to the bracket 1. A filter hole is opened in the mounting base 61. A recovery hole 63 is opened on the side of the mounting base 61 near the conveying device 4. The filter screen 62 is installed in the filter hole and divides the filter hole into an upper chamber and a lower chamber. The upper chamber is connected to the recovery hole 63. A through hole 11 is opened at the top of the bracket 1. The filter screen 62 is inclined towards the through hole 11. One end of the bracket 1 is connected to the recovery device 7. The through hole 11 connects the recovery hole 63 and the recovery device 7. The other end of the recovery device 7 is connected to the stirring device 3. The recovery device 7 is used to transport large plastic particles that cannot be filtered back into the stirring device 3. During operation, the drive motor 5 drives the conveying device 4 to operate, and the stirring device 3 stirs the plastic granules, causing them to fall into the inclined rotating conveying device 4 below. The conveying device 4 conveys the plastic granules upward to the filtering mechanism 6 for filtration. After screening and filtration, large plastic granules enter the recycling device 7 through the top through hole 11 of the support 1. The recycling device 7 then conveys them back to the stirring device 3. Small plastic granules pass through the filter screen 62 of the filtering mechanism 6, are discharged from the filter hole through the recycling channel, and finally fall from the recycling hole 63 of the mounting base 61 into the discharge port of the external plastic granule processing equipment directly opposite it.

[0027] The conveying device 4 includes a conveying pipe 41 and a spiral blade 42. The spiral blade 42 is installed inside the conveying pipe 41. The upper end of the conveying pipe 41 is a first discharge port 411, which is supported by a bracket 1. The lower end of the conveying pipe 41 is provided with a first discharge port 412, which is connected to the input end of the stirring device 3. The upper end of the conveying pipe 41 is supported by the bracket 1, and the lower end of the conveying pipe 41 is installed on a support base 2. After being stirred, the plastic granules enter the conveying pipe 41 from the first discharge port 412. The spiral blade 42 pushes the plastic granules upward and discharges them from the first discharge port 411.

[0028] The spiral blades 42 are wrapped around the rotating shaft 43, which is connected to the output end of the drive motor 5. The drive motor 5 drives the spiral blades 42 to rotate inside the conveying pipe 41. The drive motor 5 is mounted on the support base 2, and its output end passes through the conveying pipe 41. By driving the spiral blades 42 to rotate, the drive motor 5 pushes the plastic granules upward along the inner wall of the conveying pipe 41, and then discharges them from the first discharge port 411 at the upper end of the conveying pipe 41, thus completing the plastic granule feeding and conveying process.

[0029] The support base 2 includes a base 21 and a support plate 22. The base 21 and the support plate 22 are connected by support feet 23. The stirring device 3 passes through the support plate 22 and is mounted on the support plate 22. The lower end of the stirring device 3, the first discharge port 412 of the conveying pipe 41, and the drive motor 5 are all located inside the base 21. The support base 2 is used to install the stirring device 3 to fix the relative position of the stirring device 3 and the conveying device 4, ensuring that the plastic granules can smoothly enter the conveying pipe 41 from the stirring device 3.

[0030] The mixing device 3 is a mixer 31. The upper end of the mixer 31 has a second discharge port 32, which is a funnel structure. The lower end of the mixer 31 has a second discharge port 33, through which plastic granules can be conveyed to the first discharge port 412. When the plastic granules enter the mixer 31 from the second discharge port 32, the mixer 31 starts and begins mixing, ensuring the granules are thoroughly mixed inside and move downwards. Finally, the mixed plastic granules are discharged through the second discharge port 33 at the lower end of the mixer 31 and accurately conveyed to the first discharge port 412 at the lower end of the conveying pipe 41 of the conveying device 4, preparing for subsequent conveying and processing.

[0031] The recycling device 7 includes two conveyor plates 71. One end of each conveyor plate 71 is connected to a through hole 11, and the other end of each conveyor plate 71 bypasses a conveying pipe 41 and is connected to a second discharge port 32. The two conveyor plates 71 are symmetrically arranged with the conveying pipe 41 as the center. Large plastic particles enter the recycling channel through the through hole 11 at the top of the support 1 and then fall onto the upper end of the two conveyor plates 71. The two conveyor plates 71 are symmetrically arranged with the conveying pipe 41 as the center, bypassing the conveying pipe 41 to convey the large plastic particles to the second discharge port 32 of the mixer 31, and then circulate and mix them inside the mixer 31 from the side of the second discharge port 32.

[0032] The top of the second discharge port 32 is lower than the mounting base 61. After the plastic particles are screened by the filter screen 62, the large plastic particles slide back from the conveyor plate 71 due to gravity and are repeatedly stirred.

[0033] like Figure 4As shown, a storage hopper 8 is installed on the mounting base 61, into which the conveying pipe 41 extends. The storage hopper 8 is connected to the filter hole. The storage hopper 8 can prevent excessive accumulation of plastic particles on the mounting base 61 after they are discharged from the conveying pipe 41, thus avoiding leakage from the edge of the mounting base 61 and resulting in waste of materials.

[0034] Working Principle: This device utilizes the rotation of the spiral blades 42 within the conveying pipe 41 to generate thrust, transporting plastic granules upwards along the inclined conveying pipe 41. This achieves automatic feeding, replacing manual feeding, improving work efficiency, and providing a stable and continuous supply of raw materials to the plastic granule processing equipment. The filter mechanism 6 is designed based on the principle of sieving; the pore size of the filter screen 62 determines the filtration standard for plastic granules. Fine particles can pass smoothly through the filter screen 62 into the processing equipment, while larger particles are intercepted because their size exceeds the pore size of the filter screen 62. This process effectively screens the plastic granules, ensuring that the particle size of the plastic granules entering the processing equipment meets the processing requirements and improving processing quality. The recycling device 7 returns large plastic granules that do not meet the filtration requirements to the mixing device 3, avoiding resource waste and maintaining the material balance of the entire feeding system, ensuring that the plastic granules are fully utilized and processed.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
