Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a feeding platform for polypropylene production. Background Technology

[0002] Polypropylene is a polymer material widely used in industry and daily life. To acquire specific properties or meet the needs of practical applications, ordinary polypropylene purchased directly from the market often requires further processing. Specifically, this involves adding small amounts of specific additives to ordinary polypropylene. These additives can improve its physical, chemical, or mechanical properties. The mixed material is then fed back into processing equipment, thoroughly stirred to ensure uniform dispersion, and then extruded at high temperature. Finally, it undergoes cooling and granulation processes to obtain modified polypropylene granules with the desired characteristics, meeting the requirements of different applications.

[0003] Before mixing, bagged polypropylene raw materials need to be manually placed at the feeding port on a high platform. However, bagged polypropylene raw materials are usually lifted upwards by forklifts and have to be carried a long distance from the forklifts to reach the platform, which makes feeding extremely inconvenient. Therefore, it is necessary to design a feeding platform for polypropylene production. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a feeding platform for polypropylene production.

[0005] The objective of this utility model can be achieved through the following technical solution: A feeding platform for polypropylene production includes a mounting frame, a platform fixed on the mounting frame, and at least one feeding port on the platform. The platform is characterized by having several cantilever beams fixed on it, a base arranged below the platform, a movable frame horizontally slidably connected to the base, the movable frame being horizontally moved by a power motor, and an L-shaped lifting platform vertically slidably connected to the movable frame. One end of the L-shaped lifting platform is fixedly connected to one end of several placement beams, and the other end of each placement beam is fixedly connected to the other end of the L-shaped lifting platform via a support column, allowing the placement beams to pass through the cantilever beams. A cylinder is mounted on the movable frame via a fixing block, the piston rod of the cylinder is rotatably connected to the middle of a linkage shaft, a sprocket is fixed to the end of the linkage shaft, the fixing block is also fixedly connected to one end of a chain, and the other end of the chain is fixedly connected to one end of the L-shaped lifting platform, with the chain meshing with the sprocket.

[0006] A guide rail is fixed on the base, and a movable plate is slidably connected to the guide rail. The movable plate is fixedly connected to the movable frame. A guide rail is fixed on the movable frame, and the L-shaped lifting platform is slidably connected to the guide rail via guide wheels.

[0007] A ladder is also fixed to the mounting frame.

[0008] Both the mounting frame and the platform are equipped with guardrails.

[0009] Compared with existing technologies, this polypropylene production feeding platform has the following advantages:

[0010] In this invention, bagged polypropylene raw materials are placed on a placement beam, and the direction of the feeding port is moved. When the placement beam moves above the cantilever beam, the distance between the bagged polypropylene raw materials and the feeding port is relatively close, and the raw materials on the placement beam can be manually moved to the feeding port for manual feeding, which is convenient.

Detailed Implementation

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figures 1-2As shown, this polypropylene production feeding platform includes a mounting frame 4, on which a platform 6 is fixed. The platform 6 has at least one feeding port 5; in this embodiment, there are two feeding ports 5. Several cantilever beams 8 are fixed on the platform 6. In this embodiment, the distance between two connected cantilever beams 8 is just enough to allow a beam 9 to pass through, while also allowing workers to walk normally on the cantilever beams 8. A base 1 is arranged below the platform 6, and a movable frame 12 is horizontally slidably connected to the base 1. The movable frame 12 is horizontally moved by a power motor 14, which is a prior art technique. An L-shaped lifting platform 11 is vertically slidably connected to the movable frame 12. One end of the placement beam 9 is fixedly connected to one end of several placement beams 9. The other end of the placement beam 9 is fixedly connected to the other end of the L-shaped lifting platform 11 through the support column 15. The placement beam 9 can pass through the cantilever beam 8. In this embodiment, multiple bags of packaged polypropylene raw materials can be normally placed on the several placement beams 9. A cylinder 10 is installed on the moving frame 12 through a fixing block 16. The piston rod of the cylinder 10 is rotatably connected to the middle of the linkage shaft 18. A sprocket 19 is fixed at the end of the linkage shaft 18. The fixing block 16 is also fixedly connected to one end of the chain 17. The other end of the chain 17 is fixedly connected to one end of the L-shaped lifting platform 11. The chain 17 and the sprocket 19 mesh. With this structure, the L-shaped lifting platform 11 can be smoothly raised and lowered through the cooperation of the cylinder 10, the chain 17 and the sprocket 19.

[0016] A guide rail 1 is fixed on the base 1, and a movable plate 13 is slidably connected to the guide rail 12. The movable plate 13 is fixedly connected to the movable frame 12. A guide rail 20 is fixed on the movable frame 12, and the L-shaped lifting platform 11 is slidably connected to the guide rail 20 via guide wheels 21.

[0017] A ladder 3 is also fixed to the mounting frame 4. This structure allows workers to easily access the platform 6 via the ladder 3.

[0018] Both the mounting bracket 4 and the platform 6 are fixed with guardrails 7.

[0019] In this invention, bagged polypropylene raw materials are placed on the placement beam 9, and the direction of the feed inlet is moved. When the placement beam 9 moves above the cantilever beam 8, the distance between the bagged polypropylene raw materials and the feed inlet 5 is relatively close, and the raw materials on the placement beam 9 can be manually transported to the feed inlet 5 for manual feeding, which is convenient.

[0020] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
