[0013] The present invention will now be described in detail with reference to the accompanying drawings, as shown below. Figure 1 and attached Figure 2 As shown, a feeding machine for producing plastic granules includes a storage bin 1, with the bottom center of the storage bin 1 recessed downwards; support legs 2 are fixedly connected to the lower four sides of the storage bin 1, and a feeding pipe is integrally connected to the opening in the lower center of the storage bin 1, wherein a solenoid valve 3 is fixedly connected to the lower end of the feeding pipe; an air suction pipe 4 is integrally connected to the opening in the upper center of the storage bin 1, and a filter screen 5 is fixedly connected inside the air suction pipe 4; a centrifugal fan 6 is fixedly connected to the upper end of the air suction pipe 4; and a feed pipe 7 is integrally connected to the opening on the upper right side of the storage bin 1.

[0014] One type of feeding machine for producing plastic granules also includes a mixing and suction component 8, which is connected to the outer wall of the feed pipe 7. This facilitates the vacuum suction effect, effectively solving the problem of inconvenient material addition and eliminating the need for operators to use heightening devices, thereby eliminating safety hazards.

[0015] In this implementation plan, in conjunction with the appendix Figure 3As shown, the material mixing and suction assembly 8 includes a suction pipe 81, with a connecting pipe 82 integrally connected to the upper left opening of the suction pipe 81, and the left end of the connecting pipe 82 is inclined upward; a drive motor 83 is fixedly connected to the upper end of the suction pipe 81, and the lower end of the output shaft of the drive motor 83 passes through the upper middle part of the connecting pipe 82; a rotating shaft 84 is provided on the inner side of the suction pipe 81, and the upper end of the rotating shaft 84 is connected to the lower end of the output shaft of the drive motor 83 through a coupling; a spiral stirring plate 85 is fixedly connected to the outer wall of the rotating shaft 84, and the spiral stirring plate 85 is located on the lower side of the suction pipe 81; operating handles 86 are fixedly connected to the front and rear sides of the upper side of the outer wall of the suction pipe 81, respectively.

[0016] In this embodiment, specifically, the left end of the connecting pipe 82 is connected to the right end of the feed pipe 7.

[0017] In this embodiment, specifically, the suction pipe 81 is a stainless steel pipe with a circular cross-section.

[0018] In this embodiment, specifically, the rotating shaft 84 is a stainless steel shaft with a circular cross-section.

[0019] In this embodiment, specifically, the spiral mixing plate 85 is made of spiral stainless steel plate.

[0020] In this implementation scheme, specifically, the filter screen 5 is a primary plate air filter.

[0021] In this embodiment, specifically, the solenoid valve 3, centrifugal fan 6, and drive motor 83 are electrically connected to an external control panel.

[0022] In this implementation scheme, when using this feeding machine, the operator can fix the lower end of the support leg 2 to the external plastic processing equipment and align the solenoid valve 3 with the inlet of the plastic processing equipment. During feeding, the operator can control the solenoid valve 3 to open via the external control panel. At this time, the plastic granules in the storage tank 1 will directly enter the plastic processing equipment through the solenoid valve 3, achieving the effect of convenient feeding. When it is necessary to add raw materials to the storage tank 1, the operator can control the solenoid valve 3 to close via the external control panel and simultaneously control the centrifugal fan 6 to start. The centrifugal fan 6 will draw air from the storage tank 1 through the suction pipe 4, creating a negative pressure inside the storage tank 1. At this time, the feed pipe 7 will produce... The suction force is generated because the feed pipe 7 is connected to the connecting pipe 82 through the pipeline, so the lower end of the suction pipe 81 also has suction force. Then, the operator can insert the suction pipe 81 into the external plastic granules through the operating handle 86. The plastic granules are sucked into the suction pipe 81 and enter the storage tank 1 through the connecting pipe 82, the pipeline and the feed pipe 7, thus completing the addition of raw materials. Compared with the prior art, this utility model does not require the use of a heightening device when adding raw materials to the storage tank 1. It only needs to insert the suction pipe 81 directly into the packaging bag of the plastic granules to achieve the effect of vacuum suction, which can effectively solve the problem of inconvenience in adding raw materials. It eliminates the need for the operator to use a heightening device, thereby eliminating safety hazards. During the process of adding raw materials, the operator can also control the drive motor 83 to start through the external control panel. The drive motor 83 drives the spiral mixing plate 85 to rotate through the rotating shaft 84, thereby making the spiral mixing plate 85 agitate the raw materials and convey them upward, thus ensuring the continuity of suction by the suction pipe 81.

[0023] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution of this utility model, falls within the protection scope of this utility model.
